    Practical abilities are important for students from majors including Computer Science and Engineering, and Electrical Engineering. Along with the popularity of ACM International Collegiate Programming Contest (ACM/ICPC) and other programming contests, online judge (OJ) websites achieve rapid development, thus providing a new kind of programming practice, i.e. online practice. Due to fair and timely feedback results from OJ websites, online practice outperforms traditional programming practice. In order to promote students' practical abilities in programming and algorithm designing, this article presents a novel teaching idea, online judge & practice oriented teaching (OJPOT). OJPOT is applied to Programming Foundation course. OJPOT cultivates students' practical abilities through various kinds of programming practice, such as programming contests, online practice and course project. To verify the effectiveness of this novel teaching idea, this study conducts empirical research. The experimental results show that OJPOT works effectively in enhancing students' practical abilities compared with the traditional teaching idea.

    2014-01-01

    Objective. To design, implement, and evaluate a faculty development program intended to orient nonpharmacist faculty members to pharmacy practice. Design. A multifaceted program was implemented in 2012 that included 4 shadowing experiences in which faculty members visited acute care, ambulatory care, hospital, and community pharmacy settings under the guidance of licensed preceptors. Itineraries for each visit were based on objective lists of anticipated practice experiences that define the role of the pharmacist in each setting. Assessment. The 4 shadowing experiences culminated with reflection and completion of a survey to assess the impact of the program. All of the faculty participants agreed that the experience improved their conceptual understanding of contemporary pharmacy practice and the role of the pharmacist in the healthcare setting. The experience also improved faculty comfort with creating practice-relevant classroom activities. Conclusions. A shadowing experience is an effective way of orienting nonpharmacist faculty members to the practice of pharmacy. This program inspired the creation of an experience to introduce pharmacy practice faculty to pharmaceutical science faculty research initiatives. PMID:24954946

  8. Social Workers’ Orientation Toward the Evidence-Based Practice Process

    PubMed Central

    Kolmer, Deirdre M. Beneken genaamd; Schalk, René

    2014-01-01

    Objectives: This study assesses social workers’ orientation toward the evidence-based practice (EBP) process and explores which specific variables (e.g. age) are associated. Methods: Data were collected from 341 Dutch social workers through an online survey which included a Dutch translation of the EBP Process Assessment Scale (EBPPAS), along with 13 background/demographic questions. Results: The overall level of orientation toward the EBP process is relatively low. Although respondents are slightly familiar with it and have slightly positive attitudes about it, their intentions to engage in it and their actual engagement are relatively low. Respondents who followed a course on the EBP process as a student are more oriented toward it than those who did not. Social workers under 29 are more familiar with the EBP process than those over 29. Conclusions: We recommend educators to take a more active role in teaching the EBP process to students and social workers.

    Petchey, R

    1994-01-01

    BACKGROUND. Research into general practitioners' responses to the changes in the health service has focused on the quantifiable dimensions of workload, stress, job satisfaction and mental health. AIM. This study set out to investigate general practitioners' practice orientations and responses to change. METHOD. The study was undertaken in 1992. 'Young principals' who had attended MSD Foundation regional courses were invited by letter to reflect on recent change in general practice and to give their views on morale and recruitment. RESULTS. Forty nine young principals responded (response rate 45%). Responses were found to cluster around four orientations to practice: collectivism, pragmatism, traditionalism, and alienation. These varied in terms of four underlying values: autonomy, individualism, external referent and optimism. CONCLUSION. General practitioners' responses to change are more complex than is currently understood and are influenced by orientation to practice. In a relatively homogeneous 'enthusiastic' subgroup of general practitioners there is striking variation in practice orientation. PMID:7748665

    PubMed

    Lukasczik, M; Löffler, S; Gerlich, C; Wolf, H-D; Neuderth, S

    2011-06-01

    Vocational orientation in medical rehabilitation has become an important issue in rehabilitation science and practice in Germany. Although a variety of vocationally oriented interventions has been developed in recent years, there is still a lack of consensus with regard to the definition of specific types of interventions as well as relevant criteria (e. g., methods; instruments; duration/frequency; patient groups). Building on preliminary definitions, basic types of vocationally oriented measures/interventions were conceptually modified and refined in the context of a consensual process. 39 experts of various professions were contacted during a 2-stage Delphi survey to evaluate existing definitions of vocationally oriented interventions using key questions. Standardized descriptions of 5 vocationally oriented basic interventions were specified in cooperation with an interdisciplinary panel of experts. Descriptions were published in a workbook and a homepage for researchers and clinicians, which also contain information on the implementation of measures into rehabilitative care as well as good practice examples. The media developed in this project may contribute to the transfer of research results on vocationally oriented rehabilitation into health care practice. PMID:21626462

    This article continues a fairly recent trend of research examining the teaching practice of university mathematics lecturers. A lecturer's pedagogical practices in a course in linear algebra were discussed via a supportive community of inquiry. We use Schoenfeld's framework describing the relationship of resources, orientations and goals to decision-making to analyse this practice. The lecturer's overarching goal of assisting students to see the 'big picture' and the methods he employed to do so, arising from his beliefs, values and preferences are described. An example of this approach in action is presented along with possible pedagogical implications.

  17. Employee orientation: the key to lasting and productive results.

    PubMed

    Mishra, J M; Strait, P

    1993-03-01

    A large body of research emphasizes the importance of planning, commitment, and communication of the corporate culture, and the role of key personnel, supervisors, and colleagues in shaping the attitude of the new employee. Ineffective orientation programs usually fall short in meeting these requirements and therefore are costly to the organization. An endless cycle ensues: recruitment, selection, ineffective orientation, improper training, job dissatisfaction, poor performance, turnover, and loss of productivity; recruitment, selection, and so on. Effective orientation programs are designed as a process, customized to meet the needs of the organization, and they consider all of the requirements needed to be successful. The resulting picture can be painted differently: recruitment, selection, effective orientation, training, job satisfaction, improved performance, retention, and increased productivity. Of course this cycle also must be repeated under certain circumstances, but not for the same reasons and certainly not as often. Instead of increased costs, there is actually a cost savings.

  18. The orginization of medical practice and practice orientations among physicians in prepaid and nonprepaid primary care settings.

    PubMed

    Mechanic, D

    1975-03-01

    Data are presented on office-based general practitioners and pediatricians working in varying practice settings. Fee-for-service physicians spend more time in direct patient care activities than those in prepaid practice, and devote more time to each patient. The data suggest that the patient load characteristic of general practice in prepaid groups encourages a more assembly line practice which is less responsive to patients than the pattern characteristic of fee-for-service practice. Prepaid physicians work during scheduled hours and may deal with increased load by processing patients more rapidly. Fee-for-service physicians tend to respond to increased demand by working longer hours. The responsiveness of primary care physicians to patient problems seems to reflect primarily their social orientations to medical practice and the time pressures they face. Varying practice settings result in different techniques of coping with the pressures of practice. Data are also presented on sociodemographic and professional characteristics of primary care physicians in varying settings, workload, use of diagnostic and laboratory procedures, social orientations to medical practice, satisfactions and dissatisfactions, and attitudes toward sociopolitical aspects of medical care. Suggestions are offered for improving the responsiveness of prepaid practice. PMID:1113557

    2016-01-01

    Health professionals need to have current knowledge and skills in nutrition. The knowledge and skills have to be acquired in programs of continuing medical education, but also in undergraduate medical education. The main purpose of this work was to develop and implement a practice-oriented training program in nutrition and healthy eating for medical students. The subject named "Nutrition" was implemented into second-year medical curriculum. We defined a theoretical framework and terms such as nutrition, healthy eating, and evidence-based nutrition. In order to get learning outcomes we constructed a method of patients counseling and training "Individual food pyramid". The making of "Individual food pyramid" is a key integrate element of the program. It helps to memorize, understand and apply the basic principles of healthy eating in real life contexts. The final program consists of two sections: "General Nutrition" and "Special Nutrition". The most important intended learning outcome is student's lifestyle improvement. The program is practice-oriented and outcome-based. PMID:27228710

    1997-07-01

    Dielectric constant measurements of a K0.989Li0.011TaO3 crystal are performed in the orientational glass low-temperature phase. Aging and ergodicity breaking are studied through isothermal decays and temperature cycles. New results are obtained on the response of the sample to temperature jumps: three processes, with very different time scales, are put in evidence. This allows to propose a new interpretation of previous experiments and, in particular, to present a new solution of the paradox observed for the negative temperature cycles.

  6. Instructional practices in chemistry classrooms across North Carolina: An investigation of inquiry-oriented instruction

    NASA Astrophysics Data System (ADS)

    McDuffie, Sarah Faye

    The purpose of this study was to determine the extent to which chemistry teachers across North Carolina were engaging in inquiry-oriented instruction and the relationship between inquiry-oriented instruction and the eight demographic factors: level of teacher's education, years of teaching experience, gender, ethnicity, academic level of class, class size, school setting, and type of class schedule. The behaviors used to identify inquiry-oriented instruction practiced by North Carolina chemistry teachers (Flick, 1997; Keys, 1994; Layman, 1996; Priestley, Priestley & Schmucker, 1997; Rowe, 1973; Young, Brett, Squires & Lemire, 1995) were: (1) Teacher encourages student inquiry by posing thoughtful, open-ended questions or by posing authentic problems. (2) Teacher emphasizes process and uses terminology such as classify, analyze, predict, and create. (3) Teacher organizes small cooperative-learning groups for the purpose of generating, sharing or interpreting information, or for practicing skills. (4) Teacher engages students in experimentation that is integrated with theories from disciplines. (5) Teacher uses raw data as a primary source of post-laboratory student/student and student/teacher interaction. (6) Teacher models or demonstrates problem clarification, collection and interpretation of information, and application to new situations. A survey containing 10 items on demographic factors and 12 items on teaching practices was mailed to a random sample of 412 chemistry teachers (from a comprehensive list of 624 chemistry teachers provided by the North Carolina Department of Public Instruction). After 12 weeks, 252 chemistry teachers returned completed surveys. Data were analyzed to determine the respondents' reported level of inquiry-oriented instruction, which was designated, on a continuum from engaging in no inquiry-oriented instruction to engaging in total inquiry-oriented instruction. Subsequent telephone interviews were conducted with a random sample of 12

  8. Practicing the practice: Learning to guide elementary science discussions in a practice-oriented science methods course

    NASA Astrophysics Data System (ADS)

    Shah, Ashima Mathur

    University methods courses are often criticized for telling pre-service teachers, or interns, about the theories behind teaching instead of preparing them to actually enact teaching. Shifting teacher education to be more "practice-oriented," or to focus more explicitly on the work of teaching, is a current trend for re-designing the way we prepare teachers. This dissertation addresses the current need for research that unpacks the shift to more practice-oriented approaches by studying the content and pedagogical approaches in a practice-oriented, masters-level elementary science methods course (n=42 interns). The course focused on preparing interns to guide science classroom discussions. Qualitative data, such as video records of course activities and interns' written reflections, were collected across eight course sessions. Codes were applied at the sentence and paragraph level and then grouped into themes. Five content themes were identified: foregrounding student ideas and questions, steering discussion toward intended learning goals, supporting students to do the cognitive work, enacting teacher role of facilitator, and creating a classroom culture for science discussions. Three pedagogical approach themes were identified. First, the teacher educators created images of science discussions by modeling and showing videos of this practice. They also provided focused teaching experiences by helping interns practice the interactive aspects of teaching both in the methods classroom and with smaller groups of elementary students in schools. Finally, they structured the planning and debriefing phases of teaching so interns could learn from their teaching experiences and prepare well for future experiences. The findings were analyzed through the lens of Grossman and colleagues' framework for teaching practice (2009) to reveal how the pedagogical approaches decomposed, represented, and approximated practice throughout course activities. Also, the teacher educators

    2014-08-01

    Despite the salience of behavioral autonomy and independence to parent-child interactions during middle adolescence, little is known about parenting processes pertinent to youth autonomy development for Latino families. Among a diverse sample of 684 Latino-origin parent-adolescent dyads in Houston, Texas, this study examines how parents' cultural orientations are associated directly and indirectly, through parental beliefs, with parenting practices giving youth behavioral autonomy and independence. Informed by social domain theory, the study's parenting constructs pertain to youth behaviors in an "ambiguously personal" domain-activities that adolescents believe are up to youth to decide, but which parents might argue require parents' supervision, knowledge, and/or decision-making. Results for latent profile analyses of parents' cultural identity across various facets of acculturation indicate considerable cultural heterogeneity among Latino parents. Although 43% of parents have a Latino cultural orientation, others represent Spanish-speaking/bicultural (21%), bilingual/bicultural (15%), English-speaking/bicultural (15%), or US (6%) cultural orientations. Structural equation modeling results indicate that bilingual/bicultural, English-speaking/bicultural, and US-oriented parents report less emphasis on the legitimacy of parental authority and younger age expectations for youth to engage in independent behaviors than do Latino-oriented parents. Parental beliefs endorsing youth's behavioral independence and autonomy, in turn, are associated with less stringent parental rules (parental report), less parental supervision (parental and youth report), and more youth autonomy in decision-making (parental and youth report). Evidence thus supports the idea that the diverse cultural orientations of Latino parents in the US may result in considerable variations in parenting processes pertinent to Latino adolescents' development.

    There is great variability in acetabular component orientation following hip replacement. The aims of this study were to compare the component orientation at impaction with the orientation measured on post-operative radiographs and identify factors that influence the difference between the two. A total of 67 hip replacements (52 total hip replacements and 15 hip resurfacings) were prospectively studied. Intra-operatively, the orientation of the acetabular component after impaction relative to the operating table was measured using a validated stereo-photogrammetry protocol. Post-operatively, the radiographic orientation was measured; the mean inclination/anteversion was 43° (sd 6°)/ 19° (sd 7°). A simulated radiographic orientation was calculated based on how the orientation would have appeared had an on-table radiograph been taken intra-operatively. The mean difference between radiographic and intra-operative inclination/anteversion was 5° (sd 5°)/ -8° (sd 8°). The mean difference between simulated radiographic and intra-operative inclination/anteversion, which quantifies the effect of the different way acetabular orientation is measured, was 3°/-6° (sd 2°). The mean difference between radiographic and simulated radiographic orientation inclination/anteversion, which is a manifestation of the change in pelvic position between component impaction and radiograph, was 1°/-2° (sd 7°). This study demonstrated that in order to achieve a specific radiographic orientation target, surgeons should implant the acetabular component 5° less inclined and 8° more anteverted than their target. Great variability (2 sd about ± 15°) in the post-operative radiographic cup orientation was seen. The two equally contributing causes for this are variability in the orientation at which the cup is implanted, and the change in pelvic position between impaction and post-operative radiograph.

    2014-01-01

    Background Lesbian, gay, bisexual, and transgender individuals are at higher risk for substance use and substance use disorders than heterosexual individuals and are more likely to seek substance use treatment, yet sexual orientation and gender identity are frequently not reported in the research literature. The purpose of this study was to identify if sexual orientation and gender identity are being reported in the recent substance use literature, and if this has changed over time. Method The PsycINFO and PubMed databases were searched for articles released in 2007 and 2012 using the term “substance abuse” and 200 articles were randomly selected from each time period and database. Articles were coded for the presence or absence of sexual orientation and gender identity information. Results Participants’ sexual orientation was reported in 3.0% and 4.9% of the 2007 and 2.3% and 6.5% of the 2012 sample, in PsycINFO and PubMed sample articles, respectively, while non-binary gender identity was reported in 0% and 1.0% of the 2007 sample and 2.3% and 1.9% of the 2012 PsycINFO and PubMed sample articles. There were no differences in rates of reporting over time. Conclusions Sexual orientation and gender identity are rarely reported in the substance abuse literature, and there has not been a change in reporting practices between 2007 and 2012. Recommendations for future investigators in reporting sexual orientation and gender identity are included. PMID:25496705

    We perform the rigorous analysis of the relaxation to equilibrium for some facilitated or kinetically constrained spin models (KCSM) when the initial distribution ν is different from the reversible one, μ. This setting has been intensively studied in the physics literature to analyze the slow dynamics which follows a sudden quench from the liquid to the glass phase. We concentrate on two basic oriented KCSM: the East model on ℤ, for which the constraint requires that the East neighbor of the to-be-update vertex is vacant and the AD model on the binary tree introduced in Aldous and Diaconis (J. Stat. Phys. 107(5-6):945-975, 2002), for which the constraint requires the two children to be vacant. It is important to observe that, while the former model is ergodic at any p≠1, the latter displays an ergodicity breaking transition at p c =1/2. For the East we prove exponential convergence to equilibrium with rate depending on the spectral gap if ν is concentrated on any configuration which does not contain a forever blocked site or if ν is a Bernoulli( p') product measure for any p'≠1. For the model on the binary tree we prove similar results in the regime p, p'< p c and under the (plausible) assumption that the spectral gap is positive for p< p c . By constructing a proper test function, we also prove that if p'> p c and p≤ p c convergence to equilibrium cannot occur for all local functions. Finally, in a short appendix, we present a very simple argument, different from the one given in Aldous and Diaconis (J. Stat. Phys. 107(5-6):945-975, 2002), based on a combination of some combinatorial results together with "energy barrier" considerations, which yields the sharp upper bound for the spectral gap of East when p↑1.

    For the protozoan species Tetrahymena a series of airplane experiments are reported, which varied gravity as an active laboratory parameter and tested for corresponding changes in geotaxic orientation of single cells. The airplane achieved alternating periods of low (0.01 g) and high (1.8 g; g = 980 cm/s) gravity by flying repeated Keplerian parabolas. The experimental design was undertaken to clearly distinguish gravity from competing aerodynamic and chemical gradients. In this way, each culture served as its own control, with gravity level alone determining the orientational changes. On average, 6.3% of the Tetrahymena oriented vertically in low gravity, while 27% oriented vertically in high-gravity phases. Simplified physical models are explored for describing these cell trajectories as a function of gravity, aerodynamic drag, and lift. The notable effect of gravity on turning behavior is emphasized as the biophysical cause of the observed negative geotaxis in Tetrahymena. A fundamental investigation of the biological gravity receptor (if it exists) and improved modeling for vertical migration in important types of ocean plankton motivate the present research.

    2008-01-01

    The concern of academics and clinicians about the alleged dichotomy between theoretical concepts and the practice of nursing has been the catalyst for the development of a pocket-sized aid for nurses, known as the Knowledge Underpinning Practice Orientation Dial (KUPOD [N]/The Dial). A mixed method approach was used incorporating a questionnaire and a focus group of educators. The Dial was introduced, as part of a module, undertaken by a cohort of second-year Diploma in Nursing (Adult Branch) students. Twenty-eight students returned the questionnaire (response rate=85%). Results revealed that the Dial was easy to use in a variety of situations and locations. Respondents used the Dial within clinical and classroom settings and for self directed study. They reported that it was a practical and effective aid to learning, assisting in correlating theory and practice. It supported reflection and enhanced confidence in the clinical area, indicating that this economically produced tool helps to bridge the theory-practice gap. The Dial is now being introduced as a learning resource to a wider range of students. PMID:18086449

  7. Hospital process orientation from an operations management perspective: development of a measurement tool and practical testing in three ophthalmic practices

    PubMed Central

    2013-01-01

    Background Although research interest in hospital process orientation (HPO) is growing, the development of a measurement tool to assess process orientation (PO) has not been very successful yet. To view a hospital as a series of processes organized around patients with a similar demand seems to be an attractive proposition, but it is hard to operationalize this idea in a measurement tool that can actually measure the level of PO. This research contributes to HPO from an operations management (OM) perspective by addressing the alignment, integration and coordination of activities within patient care processes. The objective of this study was to develop and practically test a new measurement tool for assessing the degree of PO within hospitals using existing tools. Methods Through a literature search we identified a number of constructs to measure PO in hospital settings. These constructs were further operationalized, using an OM perspective. Based on five dimensions of an existing questionnaire a new HPO-measurement tool was developed to measure the degree of PO within hospitals on the basis of respondents’ perception. The HPO-measurement tool was pre-tested in a non-participating hospital and discussed with experts in a focus group. The multicentre exploratory case study was conducted in the ophthalmic practices of three different types of Dutch hospitals. In total 26 employees from three disciplines participated. After filling in the questionnaire an interview was held with each participant to check the validity and the reliability of the measurement tool. Results The application of the HPO-measurement tool, analysis of the scores and interviews with the participants resulted in the possibility to identify differences of PO performance and the areas of improvement – from a PO point of view – within each hospital. The result of refinement of the items of the measurement tool after practical testing is a set of 41 items to assess the degree of PO from an OM

    The preclinical compulsory elective course "Ready for the Operating Room (OR)!?" [in German]: "Fit für den OP (FOP)"] was implemented for students in their second year, who were simultaneously enrolled in the gross anatomy course. The objective of the study was to determine whether the direct practical application of anatomical knowledge within the surgical context of the course led to any improvement in learning motivation, learning orientation, and ultimately examination results in the gross anatomy course, as compared with a control group. Within the scope of five teaching sessions, the students learned surgical hand disinfection, suturing techniques, and the identification of commonly used surgical instruments. In addition, the students attended five surgical demonstrations performed by surgical colleagues on cadavers. Successful learning of these basic skills was then assessed based on an Objectively Structured Practical Examination. Learning motivation and learning orientation in both subgroups was determined using the SELLMO-ST motivation test and the Approaches and Study Skills Inventory test. While a significant increase in work avoidance was identified in the control group, this was not the case for FOP participants. Similarly, an increase in the "deep approach" to learning, as well as a decrease in the "surface approach," was able to be documented among the FOP participants following completion of the course. The results suggest that students enrolled in the gross anatomy course, who were simultaneously provided with the opportunity to learn in clinical context, were more likely to be successful at maintaining learning motivation and learning orientation required for the learning process, than students who attended the gross anatomy course alone.

This survey attempts to provide insight into the current simulation practices at medical schools, hospitals, university nursing programs and community college nursing programs. Students within the MBA program at Saint Joseph's University conducted a survey of medical simulation practices during the summer 2010 semester. A total of 115 institutions responded to the survey. The survey resus discuss overall effectiveness of current simulation centers as well as the tools and techniques used to conduct the simulation activity

  10. Action versus Result-Oriented Schemes in a Grassland Agroecosystem: A Dynamic Modelling Approach

    PubMed Central

    2012-01-01

    Effects of agri-environment schemes (AES) on biodiversity remain controversial. While most AES are action-oriented, result-oriented and habitat-oriented schemes have recently been proposed as a solution to improve AES efficiency. The objective of this study was to compare action-oriented, habitat-oriented and result-oriented schemes in terms of ecological and productive performance as well as in terms of management flexibility. We developed a dynamic modelling approach based on the viable control framework to carry out a long term assessment of the three schemes in a grassland agroecosystem. The model explicitly links grazed grassland dynamics to bird population dynamics. It is applied to lapwing conservation in wet grasslands in France. We ran the model to assess the three AES scenarios. The model revealed the grazing strategies respecting ecological and productive constraints specific to each scheme. Grazing strategies were assessed by both their ecological and productive performance. The viable control approach made it possible to obtain the whole set of viable grazing strategies and therefore to quantify the management flexibility of the grassland agroecosystem. Our results showed that habitat and result-oriented scenarios led to much higher ecological performance than the action-oriented one. Differences in both ecological and productive performance between the habitat and result-oriented scenarios were limited. Flexibility of the grassland agroecosystem in the result-oriented scenario was much higher than in that of habitat-oriented scenario. Our model confirms the higher flexibility as well as the better ecological and productive performance of result-oriented schemes. A larger use of result-oriented schemes in conservation may also allow farmers to adapt their management to local conditions and to climatic variations. PMID:22496746

  11. Preserving the person: The ethical imperative of recovery-oriented practices.

    PubMed

    Atterbury, Kendall

    2014-03-01

    For more than a decade the principles of mental health recovery have been promoted as an alternative to traditional models of care. Recovery-oriented practices are those that recognize the strengths of service users and empower them within the mental health system. In contrast to a more hierarchical model of care in which service providers make decisions with a pronounced absence of input from service users, recovery-oriented practices emphasize shared decision-making, respect for service user goals, and the recognition of the full humanity of all persons in care relationships. Recovery-oriented care has yet to be embraced by the majority of service providers, however. There are several reasons for this failure but among them is the lack of attention given to the ethical ground of recovery. This article seeks to bring recovery into conversation with moral philosophy by arguing that recovery-oriented care is essentially linked to fundamental rights and values of personhood within a liberal democracy. By joining together a conception of personhood rooted in essential vulnerability and a Rawlsian perspective on justice, this article argues that recovery is not only a desirable approach to mental health practice but that it is ethically necessary. It argues that recovery practices are not exceptional interventions to be reserved for a few but that a recovery-orientation entails fundamental elements of justice and respect to which all persons are entitled.

    Investigation in the field of Alzheimer’s disease (AD), the commonest cause of dementia, has been very active in recent years and it may be difficult for the clinician to keep up with all the innovations and to be aware of the implications they have in clinical practice. The authors, thus, reviewed recent literature on the theme in order to provide the clinician with an updated overview, intended to support decision-making on aspects of diagnosis and management. This article begins to focus on the concept of AD and on its pathogenesis. Afterward, epidemiology and non-genetic risk factors are approached. Genetics, including genetic risk factors and guidelines for genetic testing, are mentioned next. Recommendations for diagnosis of AD, including recently proposed criteria, are then reviewed. Data on the variants of AD is presented. First approach to the patient is dealt with next, followed by neuropsychological evaluation. Biomarkers, namely magnetic resonance imaging, single photon emission tomography, FDG PET, PiB PET, CSF tau, and Aβ analysis, as well as available data on their diagnostic accuracy, are also discussed. Factors predicting rate of disease progression are briefly mentioned. Finally, non-pharmacological and pharmacological treatments, including established and emerging drugs, are addressed.

  13. A response to reform: Teachers' attitudes and practice of inquiry-oriented instruction

    NASA Astrophysics Data System (ADS)

    Thomas, Jeffrey D.

    The intention of the current reform effort in Connecticut is to influence the way science is taught to improve student achievement. To meet this goal, the State aligned curriculum, instruction, and assessment practices with the most recent versions of the Core Science Curriculum Framework, CAPT Handbook for Science, and the Connecticut Aptitude Performance Test (CAPT). The lack of widespread and sustainable implementation of instructional reforms, such as implementing inquiry-oriented standards-based curriculum, is an issue that has evolved out of reform efforts similar to the one in Connecticut. A possible explanation for this problem might be traced back to teacher attitudes towards the proposed instructional changes. The purpose of this qualitative case study was to explore the attitudes of six high school earth science teachers toward reform in one Connecticut suburban school district and the impact these attitudes may have had on the implementation of inquiry-oriented instructional reforms. Initially, semi-structured interviews were conducted to assess teacher attitudes toward the reform and the expected impact on the way they would enact inquiry-oriented instruction. This was followed by classroom observations of each teacher's implementation of one of the State released inquiry-oriented labs found in the CAPT Handbook for Science, so as to determine whether the labs were carried out as the teachers had intended and as was expected by the State. At the end of year, semi-structured interviews were also conducted to verify whether their attitudes changed over the course of the year. Originally, it was thought that teacher attitudes would impact the way they would carry out the State recommended labs. However, teacher attitudes in this study were only one predictor of the way the inquiry-oriented labs were implemented. Teacher experience, familiarity with the content, and knowledge of inquiry-based pedagogy also were found to be possible influences on how they

    Growing evidence from recent curriculum documents and previous research suggests that reform-oriented science teaching practices promote students' conceptual understanding, levels of achievement, and motivation to learn, especially when students are actively engaged in constructing their ideas through scientific inquiries. However, it is difficult to identify to what extent science teachers engage students in reform-oriented teaching practices (RTPs) in their science classrooms. In order to exactly diagnose the current status of science teachers' implementation of the RTPs, a valid and reliable instrument tool is needed. The principles of validity and reliability are fundamental cornerstones in developing a robust measurement tool. As such, this study was motivated by the desire to point out the limitations of the existing statistical and psychometric analyses and to further examine the validation of the RTP survey instrument. This paper thus aims at calibrating the items of the RTPs for science teachers using the Rasch model. The survey instrument scale was adapted from the 2012 National Survey of Science and Mathematics Education (NSSME) data. A total of 3701 science teachers from 1403 schools from across the USA participated in the NSSME survey. After calibrating the RTP items and persons on the same scale, the RTP instrument well represented the population of US science teachers. Model-data fit determined by Infit and Outfit statistics was within an appropriate range (0.5-1.5), supporting the unidimensional structure of the RTPs. The ordered category thresholds and the probability of the thresholds showed that the five-point rating scale functioned well. The results of this study support the use of the RTP measure from the 2012 NSSME in assessing usage of RTPs.

    2015-01-01

    Objective. This study aims to examine the relationship of diabetes care processes and patient outcomes with an expanded set of indicators regarding patient-oriented care delivery, such as treatment satisfaction, the quality of patient-physician relationship, and a wider range of patient outcomes such as self-management, health behaviour, disease-related burden, and health-related quality of life (HRQL). Methods. The study population consisted of 486 participants with type 2 diabetes in two population-based follow-up surveys, conducted in 2003 to 2005 and 2006 to 2008 in Southern Germany. Data were self-reported and questionnaire-based, including the SF-12 for HRQL. Multiple regression models were used to identify associations between care processes and outcomes with adjustment for confounders. Results. Frequent medical examinations increased the likelihood of self-monitoring activities, such as foot care. A positive patient experienced relationship with their physician is associated with higher adherence to medical recommendations, such as medication intake, and the score of the SF-12 mental component. Participants with diabetes-related complications reported higher levels of medical examinations and multiprofessional care. Conclusions. Indicators of patient-oriented care should become an indispensable part of diabetes clinical practice guidelines with the aim of striving for more effective support of patients. PMID:25859544

Results Lesbian women were 0.803 times (95% CI 0.755 to 0.854) less likely to have seen a family practitioner in the past 3 months relative to heterosexual women (bisexual women OR=0.887, 95% CI 0.817 to 0.963). Gay men were 1.218 times (95% CI 1.163 to 1.276) more likely to have seen a family practitioner relative to heterosexual men (bisexual men OR=1.084, 95% CI 0.989 to 1.188). Our results are robust to the timing of the family practitioner visit (0–3, 0–6, 0–12 months). Gay men were more likely to have seen a family practitioner than heterosexual men where the proportion of women practitioners in the practice was higher (OR=1.238, 95% CI 1.041 to 1.472). Conclusions Inequalities in the use of primary care across sexual orientation in England exist having conditioned on several measures of health status, demographic and family practitioner characteristics. The findings suggest these differences may be reduced by policies targeting a reduction of differences in patient acceptability of primary care. In particular, further research is needed to understand whether lower use among heterosexual men represents unmet need or overutilisation among gay men, and the barriers to practitioner use seemingly occurring due to the gender distribution of practices.

    A teacher's orientation toward science teaching has been proposed as very influential to a teacher's pedagogical content knowledge (PCK) and teaching practice. Experienced teachers' orientation toward science teaching and its connections to their practice has not been well explored. Focusing on a unit about the periodic table, this study provides a case study using a respected, experienced high-school chemistry teacher's orientation toward science teaching to make sense of her observed teaching practice. Aspects of her practice, which aligned and misaligned with current recommendations for science teaching, were explored. Using observations, interviews, and class documents, the study concluded that the teacher's orientation toward science teaching was an appropriate way of understanding her teaching practice. While also being shown to be a useful tool for researchers, this case provides an example how a teacher's orientation toward science teaching could help in the development of professional development, specifically professional development for the recently released Next Generation Science Standards.

  12. Professional development for primary science teaching in Thailand: Knowledge, orientations, and practices of professional developers and professional development participants

    NASA Astrophysics Data System (ADS)

    Musikul, Kusalin

    The purpose of this study was to examine an entire PD project as a case to understand the dynamic nature of science PD in a holistic manner. I used a pedagogical content knowledge model by Magnusson, Krajcik, and Borko (1999) as my theoretical framework in examining the professional developers' and teacher participants' knowledge, orientation, and practice for professional development and elementary science teaching. The case study is my research tradition; I used grounded theory for data analysis. The primary data sources were interview, card sort activity, and observation field notes collected during the PD and subsequently in teacher participants' classrooms. Secondary data sources were documents and artifacts that I collected from the professional developers and teachers. An analysis of the data led me to interpret the following findings: (a) the professional developers displayed multiple orientations. These orientations included activity-driven, didactic, discovery, and pedagogy-driven orientations. The orientations that were found among the professional developers deviated from the reformed Thai Science Education Standards; (b) the professional developers had limited PCK for PD, which were knowledge of teachers' learning, knowledge of PD strategies, knowledge of PD curriculum, and knowledge of assessment.; (c) the professional developers' knowledge and orientations influenced their decisions in selecting PD activities and teaching approaches; (d) their orientations and PCK as well as the time factor influenced the design and implementation of the professional development; (e) the elementary teachers displayed didactic, activity-driven, and academic rigor orientations. The orientations that the teachers displayed deviated from the reformed Thai Science Education Standards; and (f) the elementary teachers exhibited limited PCK. It is evident that the limitation of one type of knowledge resulted in an ineffective use of other components of PCK. This study

    Pascual, R.

    2010-03-01

    This article describes an extension to project-oriented learning to increase social construction of knowledge and learning. The focus is on: (a) maximising opportunities for students to share their knowledge with practitioners by joining communities of practice, and (b) increasing their intrinsic motivation by creating conditions for student's relatedness. The case study considers a last year capstone course in Mechanical Engineering. The work addresses innovative practices of active learning and beyond project-oriented learning through: (a) the development of a web-based decision support system, (b) meetings between the communities of students, maintenance engineers and academics, and (c) new off-campus group instances. The author hypothesises that this multi-modal approach increases deep learning and social impact of the educational process. Surveys to the actors support a successful achievement of the educational goals. The methodology can easily be extended to further improve the learning process.

    The rapidly growing industrial activities in emerging economies such as China have been causing resource depletion and pollution problems. This reality requires China to adopt an integrated management approach to resolve the conflict between industrial development and environmental protection, and the concept of circular economy (CE) serves this purpose. In this paper, we examine if different types of manufacturing enterprises on environmental-oriented supply chain cooperation (ESCC) exist. We also determine if the Chinese manufacturer types varying in ESCC differ in their implementation of the CE practices towards achieving the CE-targeted goals on improving both environmental and economic performance. Our cluster analytic results with multivariate analysis of variance (MANOVA) among the four identified types of Chinese manufacturers varying in environmental-oriented supply chain cooperation highlight the importance to intensify the cooperation with upstream and downstream supply chain partners for a CE initiative to succeed.

    The aim of this study was to develop and evaluate an online, interprofessional education programme for clinicians commencing work in rural mental health services in New South Wales, Australia. Twenty-eight participants, including nurses, psychologists, social workers and occupational therapists, completed a 24-week education programme (Introduction to Rural Mental Health Practice programme) that orientated clinicians to working in rural settings. The online programme included an orientation to online learning and clinical skills such as risk assessment, therapeutic communication and de-escalation skills applied in rural settings. Twenty-four participants provided pre- and post-evaluation responses that were matched and analysed using paired t-tests to identify any significant differences in mean scores across the domains of interest. Fifty per cent (n= 13) of participants had a background in nursing and 49% were allied health clinicians (psychologists, social workers and occupational therapists). Statistically significant improvements (P < 0.05) were detected in participant confidence in responding to common mental health problems, knowledge about the role of different services in rural mental health care, perceived safety of work and perceived self-efficacy in dealing with challenging or aggressive behaviours. The Introduction to Rural Mental Health Practice programme was successful in orienting clinicians to rural mental health but the small sample size highlights the need to evaluate the programme with a larger cohort of rural clinicians. The attrition at the early stages of the study highlights significant challenges in the retention of rural clinicians in online education programmes. Factors that promoted participation and retention included the provision of study leave and orientation to the online environment. PMID:21848598

    Since an increasing number of returning military personnel are presenting with neurological manifestations of traumatic brain injury (TBI), there has been a great focus on the effects resulting from blast exposure. It is paramount to resolve the physical mechanism by which the critical stress is being inflicted on brain tissue from blast wave encounters with the head. This study quantitatively measured the effect of head orientation on intracranial pressure (ICP) of rats exposed to a shock wave. Furthermore, the study examined how skull maturity affects ICP response of animals exposed to shock waves at various orientations. Results showed a significant increase in ICP values in larger rats at any orientation. Furthermore, when side-ICP values were compared to the other orientations, the peak pressures were significantly lower suggesting a relation between ICP and orientation of the head due to geometry of the skull and location of sutures. This finding accentuates the importance of skull dynamics in explaining possible injury mechanisms during blast. Also, the rate of pressure change was measured and indicated that the rate was significantly higher when the top of the head was facing the shock front. The results confirm that the biomechanical response of the superior rat skull is distinctive compared to other areas of the skull, suggesting a skull flexure mechanism. These results not only present insights into the mechanism of brain injury, but also provide information which can be used for designing more effective protective head gear. PMID:22947434

    This study was an examination of how science teachers' teaching abilities---content and pedagogical knowledge and skills---were affected by an inquiry-oriented science education professional development program. The study researched the characteristics of an inservice program, Microcosmos, designed to equip teachers with new perspectives on how to stimulate students' learning and to promote a self-reflective approach for the implementation of instructional practices leading to improving teachers' and students' roles in the science classroom. The Microcosmos Inservice Program, which focused on the use of microorganisms as a vehicle to teach science for middle and high school grades, was funded by the National Science Foundation and developed by the Microcosmos Project based at the School of Education, Boston University. The teacher-training program had as its main objective to show teachers and other educators how the smallest life forms---the microbes---can be a usable and dynamic way to stimulate science interest in students of all ages. It combines and integrates a number of training components that appear to be consistent with the recommendations listed in the major reform initiatives. The goal of the study was to explore weather the program provoked any change(s) in the pedagogical practices of teachers over time, and if these changes fostered inquiry-based practices in the classroom. The exploratory analysis used a qualitative methodology that followed a longitudinal design for the collection of the data gathered from a sample of 31 participants. The data was collected in two phases. Phase One - The Case History group, involved 5 science teachers over a period of seven years. Phase Two - The Expanded Teacher sample, involved 26 teachers---22 new teachers plus four teachers from Phase One---contacted at two different points on time during the study. Multiple data sources allowed for the collection of a varied and rigorous set of data for each individual in the

    Wind-blown dunes are a record of the climatic history in Titan's equatorial region. Through modeling of the climatic conditions associated with Titan's historical orbital configurations (arising from apsidal precessions of Saturn's orbit), we present evidence that the orientations of the dunes are influenced by orbital forcing. Analysis of 3 Titan general circulation models (GCMs) in conjunction with a sediment transport model provides the first direct intercomparison of results from different Titan GCMs. We report variability in the dune orientations predicted for different orbital epochs of up to 70°. Although the response of the GCMs to orbital forcing varies, the orbital influence on the dune orientations is found to be significant across all models. Furthermore, there is near agreement among the two models run with surface topography, with 3 out of the 5 dune fields matching observation for the most recent orbital cycle. Through comparison with observations by Cassini, we find situations in which the observed dune orientations are in best agreement with those modeled for previous orbital configurations or combinations thereof, representing a larger portion of the cycle. We conclude that orbital forcing could be an important factor in governing the present-day dune orientations observed on Titan and should be considered when modeling dune evolution.

    Introduction There has been limited investigation of the sexuality and sexual dysfunction in non-heterosexual subjects by the sexual medicine community. Additional research in these populations is needed. Aims To investigate and compare sexuality and sexual function in students of varying sexual orientations. Methods An internet-based survey on sexuality was administered to medical students in North American between the months of February and July of 2008. Main Outcome Measures All subjects provided information on their ethnodemographic characteristics, sexual orientation, and sexual history. Subjects also completed a series of widely-utilized instruments for the assessment of human sexuality (International Index of Erectile Function [IIEF], Female Sexual Function Index [FSFI], Premature Ejaculation Diagnostic Tool [PEDT], Index of Sex Life [ISL]). Results There were 2,276 completed responses to the question on sexual orientation. 13.2% of male respondents and 4.7% of female respondents reported a homosexual orientation; 2.5% of male and 5.7% of female respondents reported a bisexual orientation. Many heterosexual males and females reported same-sex sexual experiences (4% and 10%, respectively). Opposite-sex experiences were very common in the male and female homosexual population (37% and 44%, respectively). The prevalence of premature ejaculation (PEDT > 8) was similar among heterosexual and homosexual men (16% and 17%, P = 0.7, respectively). Erectile dysfunction (IIEF-EF < 26) was more common in homosexual men relative to heterosexual men (24% vs. 12%, P = 0.02). High risk for female sexual dysfunction (FSFI < 26.55) was more common in heterosexual and bisexual women compared with lesbians (51%, 45%, and 29%, respectively, P = 0.005). Conclusion In this survey of highly educated young professionals, numerous similarities and some important differences in sexuality and sexual function were noted based on sexual orientation. It is unclear whether the

Results of the PCA/EFA revealed three dimensions of perceived classroom assessment environment: learning-, harsh-, and public-oriented assessment environments; and three dimensions of achievement goal orientations: mastery, performance-approach, and performance-avoidance goals. Results of the HLM showed that class contextual features and teacher's teaching experience and assessment practices interacted significantly with student characteristics in influencing students' perceptions of classroom assessment environment and achievement goal orientations. The findings were compared with findings from previous studies related to classroom assessment environment and achievement goal orientations. Recommendations, implications, and suggestions for future research were discussed.

  4. Orientation patterns of stone pavements as a result of modern geomorphologic processes

    NASA Astrophysics Data System (ADS)

    Dietze, Michael; Kleber, Arno

    2010-05-01

    Stone pavements are typical surface features of climate-sensitive, arid environments. They form a tightly interlocking mosaic of clasts, covering virtually stone-free aeolian material. However, this mosaic does not generally exhibit random orientation of its constituents. Rather, there are systematic unimodal to bimodal distributions of stone length axes present. These orientation patterns may be the result of active geomorphologic processes, implying the unstable and fragile nature of this landform as well as a dominant lateral geomorphologic component, not considered in existing models of stone pavement formation. Responsible processes should be controlled by relief properties and may thus be described by topographic attributes. From three study areas (Laguna Salada, Mexico, eastern Mojave Desert and southern Sevier Basin, USA) we present measurements of pavement stone orientations and their relationship to landscape parameters. From 1 by 1 m sized plots azimuthal digital images were taken, corrected, georeferenced and length as well as orientation angle of the a- and b-axes of at least 100 stones were digitised. Subsequently, statistical parameters of circular data were calculated. From a digital elevation model relief attributes were derived to test their influence on pavement patterns. Three general types of orientation patterns were identified from all study areas: unimodal, bimodal and unoriented. These types are clustered together and may change within small lateral distance. The type of pattern is not influenced by stone dimensions or the formation character of the site (i.e. basalt flow vs. alluvial fan). Relief properties (e.g. slope length, specific catchment, inclination), controlling lateral geomorphologic processes appear to play a major role in generating orientation patterns in stone pavement surfaces. Hence, from pattern analysis the dynamic nature of these features can be drawn.

    At the Solothurn Hospitals (soH), 13 academically educated nurses are responsible for the development of nursing care with the goal to improve patient-oriented, effective, appropriate, and economic care. The strategy contains three priorities: a) expert care of single patients in demanding situations, b) sustained application of organisational methods such as primary nursing, nursing process, and skill/grade mix, and c) design and management of practice development projects related to specific patient groups. A first evaluation with qualitative and quantitative methods showed that the exemplary care of single patients by expert nurses was evaluated as positive for the patients as well as for the teams on two wards by nurses who were interviewed. After the introduction of primary nursing, the application rate was 81 to 90 % and the introduction of fall prevention methods in geriatric rehabilitation decreased the fall rate from 8.2 to 5.5 per 1000 patient days. A comparision with the literature shows that the expert nurses of soH perform both, working at the bedside and being responsible for practice development projects, as specialised Advanced Practice Nurses (APNs). APNs at the Solothurn Hospitals work also as generalists when organisational methods need to be consolidated. Their successes depend from their integration into the hierarchy and both, into the nursing as well as into the interprofessional teams. Competencies in Transformational Leadership also are essential at all management levels. PMID:21274841

    This paper describes a proposed best-practices system that will present expert knowledge in the use of CFD. The best-practices system will include specific guidelines to assist the user in problem definition, input preparation, grid generation, code selection, parameter specification, and results interpretation. The goal of the system is to assist all CFD users in obtaining high quality CFD solutions with reduced uncertainty and at lower cost for a wide range of flow problems. The best-practices system will be implemented as a software product which includes an expert system made up of knowledge databases of expert information with specific guidelines for individual codes and algorithms. The process of acquiring expert knowledge is discussed, and help from the CFD community is solicited. Benefits and challenges associated with this project are examined.

    This paper presents findings of a study, The Community Practice Project, that examined the situation of occupational therapists practising in community based settings in the province of Ontario, Canada in 1992. In addition to providing a profile of the typical community based therapist, the study considered issues relating to: the principal roles in places of employment; specific job skills and areas of professional expertise utilized in the community; and how well occupational therapists; formal training prepared them for their community oriented roles and tasks. Results indicate that great opportunities exist and job satisfaction is high in community settings. Nonetheless, therapists feel inadequately prepared for the new role of consultant and its concomitant skills in a field that has re-oriented itself toward the client and is increasingly focused on health promotion and disability prevention.

    Objective: Already during their studies, medical students should intensively train their clinical thinking and practice skills, enhancing their clinical expertise in theoretical and practical terms. Methods: Based on the findings of educational research, a new curriculum for clinical training was developed at Duesseldorf University, focussing on workplace-based teaching, learning and assessment. Results: For students in their 3rd, 4th and 5th year of study, our curriculum is based on learning with patient complaint items in regard to multidisciplinary areas of outpatient and inpatient care. For this educational format, 123 complaint items were defined and their compatibility with diseases from various disciplines was tested. Based on the complaint of a specific case, students locate the underlying disease pattern, the differential diagnostic and therapeutical procedures and thereby deepen the required knowledge in the basic subjects. Study books have been created by the clinical departments to support this process. Learning is integrated in competence-oriented and workplace-based learning and assessment, offering a close-knit contact between students and doctors. Conclusion: The concept allows the integration of theory into practice and the integration of knowledge from the basic, clinical-theoretical and clinical subjects into clinical thinking and action.

    1997-04-01

    In Germany a pilot project in patient-oriented pharmacy has been started in the Berufsgenossenschaftliche Unfallklinik Ludwigshafen to demonstrate the efficiency of this modem way of practising pharmacy in hospital. A special ward of the orthopaedic department (spinal injuries, 25 beds) was chosen for this project. Since February 1st, 1994, the pharmacists have taken over the stock management on the ward and dispense oral drugs in unit-dose systems for each patient. The pharmacists participate also in ward rounds and check the patients' medication charts in order to support and inform the physicians. So the project is a combination of improved patient care and an advisory service in pharmaceutical questions for the medical staff. In the first year of this project, which is still ongoing (February 1994-January 1995), 123 patients were treated on the ward; the average duration of stay was about 77 days. During this first year the pharmacists registered 111 questions and events leading to pharmaceutical interventions. The most important results of the project are the improvement in drug safety and more effective drug use. Other positive results are: during the course of the project the cooperation between the medical and pharmaceutical staff has been improved and the drug management by the pharmacy has resulted in a 17 per cent reduction of medication costs in comparison to the year before. All these results clearly demonstrate the success of these first steps in patient-oriented pharmacy. PMID:9151349

    Objective The purposes of this study were to (1) quantify dentists' practice patterns regarding caries prevention and (2) test the hypothesis that certain dentists' characteristics are associated with these practice patterns. Design The study used a cross-sectional study design consisting of a questionnaire survey. Participants The study queried dentists who worked in outpatient dental practices who were affiliated with the Dental Practice-Based Research Network Japan, which seeks to engage dentists in investigating research questions and sharing experiences and expertise (n=282). Measurement Dentists were asked about their practice patterns regarding caries preventive dentistry. Background data on patients, practice and dentist were also collected. Results 38% of dentists (n=72) provided individualised caries prevention to more than 50% of their patients. Overall, 10% of the time in daily practice was spent on caries preventive dentistry. Dentists who provided individualised caries prevention to more than 50% of their patients spent significantly more time on preventive care and less time on removable prosthetics treatment, compared to dentists who did not provide individualised caries prevention. Additionally, they provided oral hygiene instruction, patient education, fluoride recommendations, intraoral photographs taken and diet counselling to their patients significantly more often than dentists who did not provide individualised caries prevention. Multiple logistic regression analysis suggested that the percentage of patients interested in caries prevention and the percentage of patients who received hygiene instruction, were both associated with the percentage of patients who receive individualised caries prevention. Conclusions We identified substantial variation in dentists' practice patterns regarding preventive dentistry. Individualised caries prevention was significantly related to provision of other preventive services and to having a higher percentage

    This is an update of the report about an Object Oriented (OO) track reconstruction model, which was presented in the previous AIHENP'99 at Crete, Greece. The OO model for the Kalman filtering method has been designed for high energy physics experiments at high luminosity hadron colliders. It has been coded in the C++ programming language and successfully implemented into a few different OO computing environments of the CMS and ATLAS experiments at the future Large Hadron Collider at CERN. We shall report: (1) more performance result: (2) implementing the OO model into the new SW OO framework "Athena" of ATLAS experiment and some upgrades of the OO model itself.

    Background Reflection is defined here as a process by which, through self-conversation, one’s self and one’s behavior acquire meaning. However, people have limitations in terms of what they can express and be aware of during reflection. This finding points to the importance of facilitators. The purpose of this study was to determine what changes can be brought about through reflection dialogues on nursing practice. Methods The Participants were 9 nurses who worked at three institutions in City A, each with about 200 beds. Workplace topics were examined through self-reflections and reflection dialogues. The depth of reflection was assessed using the three levels of reflection described by Mezirow—{reflecting on the content}, {reflecting on the process} and {reflecting on the assumptions}. Results In reflecting on nursing practice, the participants were also divided into those who had already reached the highest level, {reflecting on assumptions}, via self-reflection, and those who remained at the level of {reflecting on processes}, despite the use of reflection dialogues. Conclusion The development of reflective thinking on nursing practice was connected not only to the participants’ desire to explore ways of accepting their individual experiences, but may also be connected to whether or not they are able to question themselves about their thoughts and preconceptions about nursing work.

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening. PMID:24740973

    Concepts of personal and social recovery in mental illness are constantly evolving because the journey is fluid and subject to change over time. Dynamic interactions between the complexities of human nature and mental illness create ever-altering landscapes of perplexity. The acknowledged ebb and flow of recovery in the presence of chronic and serious mental illness requires health professionals to provide a flexible suite of care, delivered through skills and methods that are responsive and meaningful to the recipient. We conducted a systematic search for qualitative literature that articulated the work of personally-supportive recovery-oriented practice (ROP) to determine the specific components of recovery-supportive work. Twenty-one articles were identified as meeting the inclusion criteria and were synthesized using a coding framework derived from Normalization Process Theory. We identified three kinds of recovery-supportive work required from health professionals: alleviating stigma, delivering effective recovery-supportive responses in the presence of complex health and social situations and managing challenges associated with the work of ROP. We discuss the resources needed for ROP and the barriers that inhibit health professionals' engagement in this work. By elucidating the work of ROP, we highlighted a disparity between health professionals' aspirations and achievements. These revelations could inform service delivery in order to better support consumer recovery in serious mental illness. PMID:27381002

    Perception of body orientation and apparent location of objects are altered when humans are using assisted means of locomotion and the resultant of the imposed acceleration and gravity is no longer aligned with the gravitational vertical. As the otolithic system cannot discriminate the acceleration of gravity from sustained inertial accelerations, individuals would perceive the resultant acceleration vector (GiA) as the vertical. However, when subjects are aligned on the GiA, an increase in the magnitude of GiA induced a lowering of the apparent visual horizon (i.e. "elevator illusion"). The main aim of this study was to quantify the contribution of body and egocentric perception in the elevator illusion. While being exposed to 1G and 1.3G and aligned on the GiA acceleration, subjects (N=20) were asked (1) to set a luminous target to the subjective horizon, (2) to set a luminous target on "straight ahead" position (egocentric task) and (3) to rotate a tilting tube to their subjective perception of body orientation. Results showed that increasing GiA lowered horizon and egocentric settings and induces a backward body tilt perception. Moreover, the elevator illusion can be expressed as the additive combination of two processes: one that is dependent on body tilt perception, and the other that is dependent on egocentric perception. Both misperceptions in hypergravity may be considered to be a consequence of excessive shearing of the otolith organs. However large inter-individual differences in body tilt perception were observed. This last result was discussed in terms of the contribution of extravestibular graviceptors. PMID:19683558

    This paper proposes a method for automatic selection of beam orientations in non-coplanar cranial IMRT. Methods of computer vision, beam's eye view techniques and neural networks are used to define a new geometry-based methodology that leads to treatment plans for cranial lesions that are comparable in quality to those generated by experienced radiation physicists. The automatic beam selection (ABS) process can be carried out in clinically useful computation times, in 1 min or less for most cases. In the process of describing the ABS process, it is shown that the cranial beam orientation optimization problem is mathematically ill posed, with the expectation that a large number of solutions will lead to similar results. Nevertheless, there are better and worse solutions and we show that the proposed ABS process, by its design, has to lead to one of the better ones. We have carried out extensive tests with 14 patients with beam selection tasks ranging from the rather simple to quite complex. The ABS process has always yielded optimizations with results that are considered good for clinic use. Seven-beam coplanar optimizations for some of the patients have also been investigated. Comparisons with non-coplanar optimizations indicate in which cases the simpler coplanar plans can be used to advantage. Parameters used in the comparisons are dose-volume histograms, minimum and maximum PTV doses, equivalent uniform doses for the PTV and OARs, and treatment volume, conformity and normal tissue indices. It is felt that the current ABS methodology is ready for extensive clinical tests.

    In this paper we present a model for coalition formation and payoff distribution in general environments. We focus on a reduced complexity kernel-oriented coalition formation model, and provide a detailed algorithm for the activity of the single rational agent. The model is partitioned into a social level and a strategic level, to distinguish between regulations that must be agreed upon and are forced by agent-designers, and strategies by which each agent acts at will. In addition, we present an implementation of the model and simulation results. From these we conclude that implementing the model for coalition formation among agents increases the benefits of the agents with reasonable time consumption. It also shows that more coalition formations yield more benefits to the agents.

    INTRODUCTION. Eslicarbazepine acetate (ESL) is a new antiepileptic drug (AED) licensed in Spain in February 2011 as an adjunctive therapy in adults with partial seizures with or without secondary generalization. Clinical trials with ESL have demonstrated acceptable efficacy and safety. AIM. To evaluate the results of ESL in our epilepsy unit during its first year of clinical experience with this AED. PATIENTS AND METHODS. We included all patients who started treatment with ESL at our epilepsy unit from March 2011 to May 2012. We collected the following variables: gender, aetiology of epilepsy, epileptogenic area, reason for switch to ESL, clinical response after initiation of ESL, adverse effects of ESL, refractoriness criteria and treatment discontinuation. A bivariate factor-to-factor correlation study was carried out to establish associations between the independent variables and the clinical response. RESULTS. We recruited 105 patients (51.4% male). 20,7% of patients remained seizure-free and 58.4% showed > 50% improvement after introduction of ESL. At 6 months, 18.1% had experienced some type of side effect, with cognitive disorders being the most common, and 11.5% had discontinued treatment. Combination with lacosamide proved to be significantly less effective in the control of seizures. Combination of ESL with the rest of sodium channel inhibitors was similar in efficacy to others combinations. CONCLUSIONS. ESL is a well-tolerated and effective AED when is used as adjunctive treatment with most of other AED in clinical practice. PMID:23483464

    A total of 1,023 urine samples sent for routine culture were plated onto sheep blood and MacConkey agars and a BBL CHROMagar Orientation (CO; Becton Dickinson, Cockeysville, Md.) plate, and the results were compared. Of these, 250 urine samples (24%) grew >10,000 CFU of one or two putative pathogens/ml and 773 showed no growth (NG), mixed growth of <10,000 CFU/ml, or three or more strains (mixed). The CO and conventional medium results agreed completely for 595 cultures with NG or <10,000 CFU/ml. An additional 178 urine samples yielded clinically insignificant differences. Both medium sets essentially agreed on quantities and identification for 400 single-pathogen cultures and 9 mixed cultures. With the caveat that CO cannot differentiate Klebsiella, Enterobacter, and Serratia spp., enteric pathogens were identified only by morphology and color on CO. Direct visual differentiation of group B streptococci from lactobacilli is not possible, but lactobacillus cells always exhibited easily recognizable morphology on Gram stain. Of 108 paired organism susceptibility results encompassing 2,268 drug-pathogen combinations, there were 3% errors and only 1% very major errors. Use of CO allowed a >50% reduction in inoculation time and a >20% reduction in work-up time. For our laboratory, with 50% “no growth” and ca. 25% significant results (50% Escherichia coli), CO allowed time and workup cost savings for a majority of cultures. A cost analysis (time and supplies for our laboratory) showed that if CO is used alone, the break-even level for CO pricing is $1.78; if CO and blood agar are both used, the break-even pricing for CO is $1.53.

  11. Practicalities and challenges in re-orienting the health system in Zambia for treating chronic conditions

    PubMed Central

    2014-01-01

    Background The rapid evolution in disease burdens in low- and middle income countries is forcing policy makers to re-orient their health system towards a system which has the capability to simultaneously address infectious and non-communicable diseases. This paper draws on two different but overlapping studies which examined how actors in the Zambian health system are re-directing their policies, strategies and service structures to include the provision of health care for people with chronic conditions. Methods Study methods in both studies included semi-structured interviews with government health officials at national level, and governmental and non-governmental health practitioners operating from community-, primary health care to hospital facility level. Focus group discussions were conducted with staff, stakeholders and caregivers of programmes providing care and support at community- and household levels. Study settings included urban and rural sites. Results A series of adaptations transformed the HIV programme from an emergency response into the first large chronic care programme in the country. There are clear indications that the Zambian government is intending to expand this reach to patients with non-communicable diseases. Challenges to do this effectively include a lack of proper NCD prevalence data for planning, a concentration of technology and skills to detect and treat NCDs at secondary and tertiary levels in the health system and limited interest by donor agencies to support this transition. Conclusion The reorientation of Zambia’s health system is in full swing and uses the foundation of a decentralised health system and presence of local models for HIV chronic care which actively involve community partners, patients and their families. There are early warning signs which could cause this transition to stall, one of which is the financial capability to resource this process. PMID:25005125

  12. Orientation effect on cone calorimeter test results to assess fire hazard of materials.

    2009-12-30

    A cone calorimeter can provide material "reaction to fire" information for use in evaluating the fire hazard of materials. Two orientations can be selected, vertical or horizontal, depending on the geometry of materials in their final use. However, most fire models and material evaluation reports fail to consider the effects of the orientation and applied the horizontal case data. To assess the validity of using data with "horizontal" samples for further applications, a systematic experimental was performed using materials including PMMA, wooden products and polystyrene foams. Besides critical heat flux for ignition, other "reaction to fire" material properties were measured, including ignition time, ignition temperature, heat release rate history and mass loss rate when exposed to three heating irradiances, namely 15, 30 and 50 kW/m(2). For the horizontal orientation in comparison to the vertical orientation, the study data reveal relatively constant temperature distribution before ignition, lower critical heat flux for pilot ignition, shorter time to ignition, lower peak heat release rate, identical total heat release, longer burning time and almost identical combustion completeness for all the tested materials except polystyrene foams. Ignition temperature displaced no clear trend. Vertical orientation tests are consequently recommended for evaluating material fire performance. PMID:19665837

    This work presents a method for the thorough research of the orientation of monuments, based on state-of-the-art geodetic and astronomical measurements. These measurements permit the production of an astronomically-oriented, digital plan of the monument, a digital diagram of the perceptible horizon around the monument, and a digital reconstruction of the apparent path of the Sun, as it rises above the horizon at characteristic dates. The data reduction procedures are rigorous and lead to an accurate determination of the orientation of the monument. The orientation is then interpreted in terms of other, mostly cultural, information about the scope of the monument and its time of construction. In retrospect, therefore, the method provides an independent determination of the time of construction of the monument within a narrow chronological range. The effectiveness and accuracy of the method is demonstrated by its application to the late Byzantine church of the Assumption of the Virgin Mary in the Greek town of Kalabaka. The orientation of the main axis of the church is geometrically determined to an accuracy of 0.6 arcminutes. Combining all geometric data with cultural and historical information, we determine the time of construction of the church (AD 1000 ± 13 years).

    The organization of cells and extracellular matrix (ECM) in native tissues plays a crucial role in their functionality. However, in tissue engineering, cells and ECM are randomly distributed within a scaffold. Thus, the production of engineered-tissue with complex 3D organization remains a challenge. In the present study, we used contact guidance to control the interactions between the material topography, the cells and the ECM for three different tissues, namely vascular media, corneal stroma and dermal tissue. Using a specific surface topography on an elastomeric material, we observed the orientation of a first cell layer along the patterns in the material. Orientation of the first cell layer translates into a physical cue that induces the second cell layer to follow a physiologically consistent orientation mimicking the structure of the native tissue. Furthermore, secreted ECM followed cell orientation in every layer, resulting in an oriented self-assembled tissue sheet. These self-assembled tissue sheets were then used to create 3 different structured engineered-tissue: cornea, vascular media and dermis. We showed that functionality of such structured engineered-tissue was increased when compared to the same qnon-structured tissue. Dermal tissues were used as a negative control in response to surface topography since native dermal fibroblasts are not preferentially oriented in vivo. Non-structured surfaces were also used to produce randomly oriented tissue sheets to evaluate the impact of tissue orientation on functional output. This novel approach for the production of more complex 3D tissues would be useful for clinical purposes and for in vitro physiological tissue model to better understand long standing questions in biology.

    Children and adolescents who are growing up gay, lesbian, bisexual, gender nonconforming, or gender discordant experience unique developmental challenges. They are at risk for certain mental health problems, many of which are significantly correlated with stigma and prejudice. Mental health professionals have an important role to play in fostering healthy development in this population. Influences on sexual orientation, gender nonconformity, and gender discordance, and their developmental relationships to each other, are reviewed. Practice principles and related issues of cultural competence, research needs, and ethics are discussed. PMID:22917211

    2007-11-01

    Previous research on organizational practices is replete with contradictory evidence regarding their effects. Here, the authors argue that these contradictory findings may have occurred because researchers have often examined complex practice combinations and have failed to investigate a broad variety of firm-level outcomes. Thus, past research may obscure important differential effects of specific practices on specific firm-level outcomes. Extending this research, the authors develop hypotheses about the effects of practices that (a) enable information sharing, (b) set boundaries, and (c) enable teams on 3 different firm-level outcomes: financial performance, customer service, and quality. Relationships are tested in a sample of observations from over 200 Fortune 1000 firms. Results indicate that information-sharing practices were positively related to financial performance 1 year following implementation of the practices, boundary-setting practices were positively related to firm-level customer service, and team-enabling practices were related to firm-level quality. No single set of practices predicted all 3 firm-level outcomes, indicating practice-specific effects. These findings help resolve the theoretical tension in the literature regarding the effects of organizational practices and offer guidance as to how to best target practices to increase specific work-related outcomes. Implications for theory, research, and practice are discussed. PMID:18020790

    Preventive health messages are often tailored to reach broad sociodemographic groups. However, within groups, there may be considerable variation in perceptions of preventive health practices, such as colorectal cancer screening. Segmentation analysis provides a tool for crafting messages that are tailored more closely to the mental models of targeted individuals or subgroups. This study used cluster analysis, a psychosocial marketing segmentation technique, to develop a typology of colorectal cancer screening orientation among 102 African American clinic patients between the ages of 50 and 74 years with limited literacy. Patients were from a general internal medicine clinic in a large urban teaching hospital, a subpopulation known to have high rates of colorectal cancer and low rates of screening. Preventive screening orientation variables included the patients' responses to questions involving personal attitudes and preferences toward preventive screening and general prevention practices. A k-means cluster analysis yielded three clusters of patients on the basis of their screening orientation: ready screeners (50.0%), cautious screeners (30.4%), and fearful avoiders (19.6%). The resulting typology clearly defines important subgroups on the basis of their preventive health practice perceptions. The authors propose that the development of a validated typology of patients on the basis of their preventive health perceptions could be applicable to a variety of health concerns. Such a typology would serve to standardize how populations are characterized and would provide a more accurate view of their preventive health-related attitudes, values, concerns, preferences, and behaviors. Used with standardized assessment tools, it would provide an empirical basis for tailoring health messages and improving medical communication. PMID:24673248

  5. Crystal orientation results in different amorphization of olivine during solar wind implantation

    Crystal orientation plays an important role in mineral amorphization during solar wind implantation. To discuss these effects, ion implantation experiments were carried out to irradiate natural olivine grains by 1 × 1017 cm-2 50 keV He+. Based on the olivine grains irradiated in our experiment, residual crystal planes have been identified by reference to the crystal plane's spacing shown in diffraction images. It is found that He+ ions injected along [010] damages the olivine structure more effectively than with other orientations and that this possibly relates to the higher atomic density and the vertical impact of the flux on MO6 (where M commonly represents Fe2+ and Mg2+) octahedra chains. Crystal planes perpendicular or approximately perpendicular to [010] may be destroyed easily during the early stages of irradiation, particularly for (040). However, crystal planes, such as (041), (021), (022), (120), and (140), parallel to [100] or [001] may survive until the final stages of olivine amorphization. These different characteristics affected by crystal orientation in ion implantation might help researchers to better understand the process of solar wind weathering and in dating the exposure time of lunar and asteroidal soil grains as well as interplanetary dust particles affected by the solar wind.

  8. Brahms An Agent-Oriented Language for Work Practice Simulation and Multi-Agent Systems Development

    NASA Astrophysics Data System (ADS)

    Sierhuis, Maarten; Clancey, William J.; van Hoof, Ron J. J.

    Brahms is a multi-agent modeling language for simulating human work practice that emerges from work processes in organizations. The same Brahms language can be used to implement and execute distributed multi-agent systems, based on models of work practice that were first simulated. Brahms demonstrates how a multi-agent belief-desire-intention language, symbolic cognitive modeling, traditional business process modeling, activity-and situated cognition theories are brought together in a coherent approach for analysis and design of organizations and human-centered systems.

    The Research Network Prevention and Rehabilitation for Mothers and Children is an association of currently 24 rehabilitation centres for mothers, fathers and their children, and a scientific team at the Hannover Medical School. The Research Network combines practice-oriented research on mother and child health with the further development of treatment programmes and the implementation of internal quality management in mother-/father-child rehabilitation centres in accordance with DIN EN ISO 9001. The present paper describes the concept of the Research Network and the work contents addressed over the last three years. The advantages and disadvantages of this association and the changes initiated in practice were evaluated from the point of view of 19 quality managers of the participating clinics. The data were collected by means of semi-structured interviews, and a qualitative content analysis was performed in order to quantify the responses. The concept of the Research Network has proven successful. In the view of the quality managers of the clinics, implementation of DIN EN ISO 9001 has lead to structuring of the processes, improved internal communication, and increased motivation in the team. The major obstacles were the lack of time and human resources. In all clinics, the participation in practice-related research projects und scientifically monitored concept development has contributed to optimizing everyday practice. The exchange between the quality managers in external quality circle meetings was of central importance. The conjunction of internal quality management, practice-related research and concept development in a network can be recommended also for other associations of clinics, health centres or medical practices.

    The size and direction of orienting movements are represented systematically as a motor map in the optic tectum of the barn owl (du Lac and Knudsen, 1990). The optic tectum projects to several distinct regions in the medial brainstem tegmentum, which in turn project to the spinal cord (Masino and Knudsen, 1992). This study explores the hypothesis that a fundamental transformation in the neural representation of orienting movements takes place in the brainstem tegmentum. Head movements evoked by electrical microstimulation in the brainstem tegmentum of the alert barn owl were cataloged and the sites of stimulation were reconstructed histologically. Movements elicited from the brainstem tegmentum were categorized into one of six different classes: saccadic head rotations, head translations, facial movements, vocalizations, limb movements, and twitches. Saccadic head rotations could be further subdivided into two general categories: fixed-direction saccades and goal-directed saccades. Fixed-direction saccades, those whose direction was independent of initial head position, were elicited from the midbrain tegmentum. Goal-directed saccades, those whose direction changed with initial head position, were elicited from the central rhombencephalic reticular formation and from the efferent pathway of the cerebellum. Particular attention was paid to sites from which fixed-direction saccadic movements were elicited, as these movements appeared to represent components of orienting movements. Microstimulation in the medial midbrain tegmentum elicited fixed-direction saccades in one of six directions: rightward, leftward, upward, downward, clockwise roll, and counterclockwise roll. Stimulation in and around the interstitial nucleus of Cajal (InC; a complete list of anatomical abbreviations is given in the Appendix) produced ipsiversive horizontal saccades. Stimulation in the ventral InC and near the dorsal and medial edges of the red nucleus produced upward saccades. Stimulation

    Few population-based surveys in the United States include sexual orientation as a demographic variable. As a result, estimating the proportion of the U.S. population that is gay, lesbian, or bisexual (GLB) is a substantial challenge. Prior estimates vary widely, from 1-21%. In 2001, questions on sexual orientation and sexual behavior were added to the Massachusetts Behavioral Risk Factor Surveillance System (MA BRFSS) and have been asked continually since that time. The purpose of this study was to determine the prevalence of adults in Massachusetts identifying as GLB and providing a demographic description of this group. The study also examined the correlation of reported sexual behavior and sexual identity within this group. Overall, 1.9% of Massachusetts adults identified as gay or lesbian and 1.0% of Massachusetts adults identified as bisexual. Of those identifying as gay or lesbian, 95.4% reported sexual behavior concordant with this identification, and 99.4% of respondents identifying as heterosexual reported behavior concordant with heterosexual sexual orientation. Among those reporting a GLB sexual orientation, men were more likely than women to identify as gay, and women were more likely than men to identify as bisexual. Younger adults (18-25 years old) were more likely than people in other age groups to identify as bisexual. Respondents with 4 or more years of education were more likely to identify as gay or lesbian than those in all other education categories. The addition of sexual orientation to population-based surveys will allow for research on the health of GLB adults and provide critical information for those charged with the creation of public policy regarding sexual orientation.

    1998-12-01

    This study examines how experiences in the family domain may magnify or mitigate experiences in the peer domain, and how processes in both milieus may influence adolescent substance use. The data derived from 666 European American mother-adolescent dyads and 510 European American father-adolescent dyads. Consistent with individuation-connectedness theory, mothers' responsiveness lessened their adolescents' orientation to peers, which, in turn, reduced adolescent substance use. This process was moderated by maternal values regarding adolescent alcohol use; that is, the relation of maternal responsiveness to adolescent substance use depended on the extent of maternal approval or disapproval of adolescent alcohol use. Among fathers, closer monitoring was directly associated with less adolescent substance use, with stronger effects among fathers who held more disapproving values regarding adolescent alcohol use. Theoretical, methodological, and pragmatic implications are given. PMID:9914646

    2014-02-01

    The advanced registered nurse practitioner (ARNP) began in the 1960s as an alternative provider to meet the demands of an escalating healthcare resource deficit. As the role evolved and ARNPs demonstrated safe and effective care, these providers began to appear in critical care settings. It is believed that in the specialty of Neurocritical Care, about half the providers are ARNPs. Hiring and training practitioners for this complex environment is daunting. At the University of Florida & Shands Jacksonville, an innovative orientation and competency model for ARNPs hired for the newly opened Neurocritical Care unit was developed and implemented. The program contains a roadmap for knowledge base and skill acquisition as well as competency training and maintenance. Experience with appropriate hiring and screening standards, internally developed training tools, and identification of necessary advanced classes are discussed. This model may be used as a guideline for Neurocritical Care ARNP training as well as adapted for all other critical care settings. PMID:24399169

  17. Speculation on martian north polar wind circulation and the resultant orientations of polar sand dunes

    1983-01-01

    Dunes in the Martian north polar erg show two dominant orientations. When seen at frost cap minimum, dunes north of 80??N record east winds, dunes south of 80??N record west winds. Many of the transverse dunes are considered to be reversing dunes. Dunes in two fields may have reversed at least once during the lifetime of the Viking Orbiters. Poor agreement exists among published predictive models of north polar winds and the interpretations derived from the major published map of the north polar dunes. We propose that the average polar winds are: (1) strong, off-pole northwest winds in fall; (2) moderate west winds in winter; (3) latitude-dependent weak to strong off-pole northeast winds in spring; and (4) weak west winds in summer. Viking images of near-polar clouds confirm much of the hypothesis. Images discussed in other studies can be given alternative interpretations that support this hypothesis also. Over millenia, the combination of reversing west and east winds could produce the binodal distributions of dune orientations observed at the north pole. ?? 1983.

    This study examined substance abuse treatment utilization across three dimensions of sexual orientation (identity, attraction, and behavior) in a large national sample of adults in the United States. Prevalence estimates were based on data collected from the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions. The sample consisted of 34,653 adults 20 years and older, and represented a population that was 52% women, 71% White, 12% Hispanic, 11% African American, 4% Asian, and 2% other race/ethnicities. An estimated 2% of the target population self-identified as lesbian, gay or bisexual; 4% reported same-sex sexual behavior, and 6% reported same-sex sexual attraction. Sexual minorities, especially women, had a greater likelihood of lifetime substance use disorders and earlier age of drinking onset. The majority of respondents with substance use disorders were untreated and lifetime substance abuse treatment utilization differed based on sexual orientation. Sexual minorities were found to have more extensive family histories of substance abuse problems. The findings indicate the underutilization of substance abuse treatment among all adults, and highlight some important factors to consider when working with sexual minorities. PMID:22444421

  19. The effect of quality management practices on operational and business results in the petroleum industry in Iran

    The trend toward globalization has challenged management thinking, organizational practices, and the ways companies interact with their customers and suppliers as well as with other segments of society. One such practice, Total Quality Management (TQM), has emerged as a management paradigm for enhancing organizational performance and profitability, to the extent that it has been regarded as "the second industrial revolution" (Kanji, 1990). Despite extensive research in quality management, little empirical research has been done on this in an international context, especially in the Middle East. This study attempts to investigate: (1) the relationship among quality management constructs based on the Malcolm Baldrige National Quality Award; and (2) the effect of quality management practices on operational and business results in the petroleum industry. A validated and reliable survey instrument was used for the study to collect data from 31 project managers/consultants in the petroleum industry in Iran. The results of the correlation analysis show that top management support is the major driver of quality management, which significantly correlates with other quality management practices. It was also found that customer orientation is not significantly correlated with external quality results (profitability). A regression analysis indicated top management support, employee training, and employee involvement as the three statistically significant variables in explaining the variability in internal quality results. Furthermore, it was found that internal quality results was statistically significant in explaining the variability of external quality results.

    The Design for Usability project aims at improving the usability of electronic professional and consumer products by creating new methodology and methods for user-centred product development, which are feasible to apply in practice. The project was focused on 5 key areas: (i) design methodology, expanding the existing approach of scenario-based design to incorporate the interaction between product design, user characteristics, and user behaviour; (ii) company processes, barriers and enablers for usability in practice; (iii) user characteristics in relation to types of products and use-situations; (iv) usability decision-making; and (v) product impact on user behaviour. The project team developed methods and techniques in each of these areas to support the design of products with a high level of usability. This paper brings together and summarizes the findings.

    2016-04-01

    The market-oriented reform in the Dutch health care system is now in its 10th year. This article offers a concise overview of some of its effects thus far on health insurance, healthcare purchasing and healthcare provision. Furthermore, attention is given to its impact on healthcare expenditures, power and trust relationships as well as the relationship between the Minister of Health and the Dutch Healthcare Authority. The reform triggered various alterations in Dutch health care some occurring quickly (e.g. health insurance), others taking longer (e.g. purchasing). These developments suggest a process of gradual transformation. The reform has instigated controversy which is increasingly framed as a power conflict between insurers and providers. Weakened consumer trust in insurers threatens the legitimacy of the reform. The relationship between Minister and Healthcare Authority appears to be more intimate than the formal independent status of this regulatory agency would suggest. PMID:26278627

    An understanding of recovery as a personal and subjective experience has emerged within mental health systems. This meaning of recovery now underpins mental health policy in many countries. Developing a focus on this type of recovery will involve transformation within mental health systems. Human systems do not easily transform. In this paper, we identify seven mis-uses (“abuses”) of the concept of recovery: recovery is the latest model; recovery does not apply to “my” patients; services can make people recover through effective treatment; compulsory detention and treatment aid recovery; a recovery orientation means closing services; recovery is about making people independent and normal; and contributing to society happens only after the person is recovered. We then identify ten empirically-validated interventions which support recovery, by targeting key recovery processes of connectedness, hope, identity, meaning and empowerment (the CHIME framework). The ten interventions are peer support workers, advance directives, wellness recovery action planning, illness management and recovery, REFOCUS, strengths model, recovery colleges or recovery education programs, individual placement and support, supported housing, and mental health trialogues. Finally, three scientific challenges are identified: broadening cultural understandings of recovery, implementing organizational transformation, and promoting citizenship. PMID:24497237

    Optimal adjuvant endocrine therapy for premenopausal women with hormone-receptor positive breast cancer has long been debated. In particular, the role of ovarian function suppression in addition to standard tamoxifen divided oncologists worldwide, and more recently, the role of aromatase inhibitors as an alternative to tamoxifen in the setting of ovarian suppression became a key question. In 2014, the long awaited results of the International Breast Cancer Study Group (IBCSG) led randomized, phase 3 trials, Suppression of Ovarian Function Trial (SOFT) and Tamoxifen and Exemestane Trial (TEXT), provided additional evidence to inform the discussion. The interpretation of the SOFT and TEXT trial data can facilitate better selection of appropriate endocrine therapy according to individual disease characteristics, recognizing the complexity of the puzzle, which is still not complete.

    Conversely to the transit photometry and radial velocity methods, the astrometric discovery of exoplanets is still limited by the sensitivity of available instruments. Furthermore, the signature of a planet (described by 7 free parameters) is orders of magnitude smaller than the standard motion of a star (5 free parameters), which has to be solved for first. This has important implications in the design and implementation of astrometric planet search surveys and the large parameter space to be explored calls for efficient fitting algorithms. I will present results of the so-far most precise astrometric planet search from the ground, targeting 20 very low-mass stars and brown dwarfs with an accuracy of 100 micro-arcseconds, which include the discovery of binaries with components in the planetary mass regime and several planet candidates with Neptune-to-Jupiter masses. The employed genetic and MCMC algorithms were shown to be efficient in constraining all astrometric parameters, which makes them important tools for the exploitation of the data currently collected by the Gaia satellite. Gaia is expected to astrometrically discover thousands of giant exoplanets and I will report on several ongoing projects in preparation of this unique harvest, including the expected yield of circumbinary planets.

  10. The classification of specialist student practice: results of an exploratory study.

    2001-08-01

    An exploratory study investigating the feasibility and acceptability of an assessment tool designed to allow practice educators(1)to classify Specialist Practitioner student practice, identifies issues of interest to all educators involved with practice assessment. Within 3 months of commencing education leading to Specialist Practitioner Awards, the spread of marks awarded for practice achievements was already consistent with final degree classification and within 6 months slightly higher than normal. By the end of the course, continued improvements in practice achievements resulted in 73% of practice marks being 70% and over. The implications for total degree classification are less catastrophic than they appear; even if this trend continues there will only be a slight increase in first class Honours degrees. Although the strategy for practice assessment includes practice educators and students working together to discuss and agree marks for practice achievements, in the study practice educators and students provided marks intentionally without discussion or consultation with each other. Two comparisons of these marks showed that many students overestimate or underestimate their practice achievements as perceived by practice educators. Continuous monitoring of how marks are determined will be a priority for the Specialist Practice team. In most cases, practice educators considered the marked assessment of practice to be a reasonable working proposition, though there were concerns about the timing of assessments and the applied terminology. The main conclusions are that some practice educators may award marks for effort, despite contradictory written comments, and that the ability of specialist students to self-assess remains an unknown quantity but a potential moderating influence. The role of the HEI will be to ensure essential preparation and ongoing support for practice educators to enable a tri-partite assessment process and to provide a robust strategy for

    2015-01-01

    Performance prediction of turbomachines is a significant part of aircraft propulsion design. In the conceptual design stage, there is an important need to quantify compressor and turbine aerodynamic performance and develop initial geometry parameters at the 2-D level prior to more extensive Computational Fluid Dynamics (CFD) analyses. The Object-oriented Turbomachinery Analysis Code (OTAC) is being developed to perform 2-D meridional flowthrough analysis of turbomachines using an implicit formulation of the governing equations to solve for the conditions at the exit of each blade row. OTAC is designed to perform meanline or streamline calculations; for streamline analyses simple radial equilibrium is used as a governing equation to solve for spanwise property variations. While the goal for OTAC is to allow simulation of physical effects and architectural features unavailable in other existing codes, it must first prove capable of performing calculations for conventional turbomachines. OTAC is being developed using the interpreted language features available in the Numerical Propulsion System Simulation (NPSS) code described by Claus et al (1991). Using the NPSS framework came with several distinct advantages, including access to the pre-existing NPSS thermodynamic property packages and the NPSS Newton-Raphson solver. The remaining objects necessary for OTAC were written in the NPSS framework interpreted language. These new objects form the core of OTAC and are the BladeRow, BladeSegment, TransitionSection, Expander, Reducer, and OTACstart Elements. The BladeRow and BladeSegment consumed the initial bulk of the development effort and required determining the equations applicable to flow through turbomachinery blade rows given specific assumptions about the nature of that flow. Once these objects were completed, OTAC was tested and found to agree with existing solutions from other codes; these tests included various meanline and streamline comparisons of axial

    The study examined US elementary teachers' knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers' knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five-year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first-year implementation of the intervention. Based on teachers' questionnaire responses and classroom observation ratings, results indicated that (1) teachers' knowledge and practices were within the bounds of acceptability but short of reform-oriented practices and (2) grade-level differences existed, especially between Grades 3 and 5.

    The paper describes stable growth of Sr(0.61)Ba(0.39)Nb2O6 (SBN) single-crystal optical fibers (grown by the laser-heated pedestal growth method) along the 100-line and 110-line crystallographic axes. The orientation of SBN fibers was investigated using transmission holograms recorded by focusing two separate, but mutually coherent, optical wavefronts into one end of the fiber. Results showed that the crystal quality of 100-line and 110-line SBN fibers grown at a given pull velocity strongly depended on the fiber diameter; generally, the quality improves with decreasing diameter.

  18. Social aspects of classroom learning: Results of a discourse analysis in an inquiry-oriented physical chemistry class

    Becker, Nicole M.

    Engaging students in classroom discourse offers opportunities for students to participate in the construction of joint understandings, to negotiate relationships between different types of evidence, and to practice making evidence-based claims about science content. However, close attention to social aspects of learning is critical to creating inquiry-oriented classroom environments in which students learn with understanding. This study examined the social influences that contribute to classroom learning in an inquiry-oriented undergraduate physical chemistry class using the Process Oriented Guided Inquiry Learning (POGIL) approach. A qualitative approach to analyzing classroom discourse derived from Toulmin's (1968) model of argumentation was used to document patterns in classroom reasoning that reflect normative aspects of social interaction. Adapting the constructs of social and sociomathematical norms from the work of Yackel and Cobb (1996), I describe social aspects of the classroom environment by discussing normative aspects of social interaction (social norms) and discipline-specific criteria related to reasoning and justification in chemistry contexts, referred to here as sociochemical norms. This work discusses four social norms and two sociochemical norms that were documented over a five-week period of observation in Dr. Black's POGIL physical chemistry class. In small group activities, the socially established expectations that students explain reasoning, negotiate understandings of terminology and symbolic representations, and arrive at a consensus on critical thinking questions shaped small group interactions and reasoning. In whole class discussion, there was an expectation that students share reasoning with the class, and that the instructor provide feedback on student reasoning in ways that extended student contributions and elaborated relationships between macroscopic, particulate, and symbolic-level ideas. The ways in which the class constructed

    Assessment of the impact of Aviation Resource Management Programs on aviation culture and performance has compelled a considerable body of research (Taylor & Robertson, 1995; Taylor, 1998; Taylor & Patankar, 2001). In recent years new methods have been applied to the problem of maintenance error precipitated by factors such as the need for self-assessment of communication and trust. The present study - 2002 -- is an extension of that past work. This research project was designed as the conclusion of a larger effort to help understand, evaluate and validate the impact of Maintenance Resource Management (MRM) training programs, and other MRM interventions on participant attitudes, opinions, behaviors, and ultimately on enhanced safety performance. It includes research and development of evaluation methodology as well as examination of psychological constructs and correlates of maintainer performance. In particular, during 2002, three issues were addressed. First, the evaluation of two (independent & different) MRM programs for changing behaviors was undertaken. In one case we were able to further apply the approach to measuring written communication developed during 2001 (Taylor, 2002; Taylor & Thomas, 2003). Second, the MRM/TOQ surveys were made available for completion on the internet. The responses from these on-line surveys were automatically linked to a results calculator (like the one developed and described in Taylor, 2002) to aid industry users in analyzing and evaluating their local survey data on the internet. Third, the main trends and themes from our research about MRM programs over the past dozen years were reviewed.

    The crystallographic preferred orientations (CPOs) were measured on a suite of samples representative of different structural depths along the West Cycladic Detachment System, Greece. Electron backscatter diffraction (EBSD) analyses were conducted on calcitic and mica schists, impure quartzites, and a blueschist, and the average seismic properties of the rocks were calculated with the Voigt-Reuss-Hill average of the single minerals' elastic stiffness tensor. The calcitic and quartzitic rocks have P- and S-wave velocity anisotropies (AVp, AVs) averaging 8.1% and 7.1%, respectively. The anisotropy increases with depth represented by the blueschist, with AVp averaging 20.3% and AVs averaging 14.5%, due to the content of aligned glaucophane and mica, which strongly control the seismic properties of the rocks. Localised anisotropies of very high magnitudes are caused by the presence of mica schists as they possess the strongest anisotropies, with values of ~ 25% for AVp and AVs. The direction of the fast and slow P-wave velocities occurs parallel and perpendicular to the foliation, respectively, for most samples. The fast propagation has the same NE-SW orientation as the lithospheric stretching direction experienced in the Cyclades since the Late Oligocene. The maximum shear wave anisotropy is subhorizontal, similarly concordant with mineral alignment that developed during extension in the Aegean. Radial anisotropy in the Aegean mid-crust is strongly favoured to azimuthal anisotropy by our results.

    Background The role of the GP in the care of sexually transmitted infections (STIs) is unclear. Aim We studied the prevalence of STI related consultations in Dutch general practice in order to obtain insight into the contribution of the GP in STI control. Design of study A descriptive study. Setting The study took place within the framework of the second Dutch National Survey of General Practice in 2001, a large nationally representative population-based survey. Method During 1 year, data of all patient contacts with the participating GPs were recorded in electronic medical records. Contacts for the same health problem were clustered into disease episodes and their diagnosis coded according to the International Classification of Primary Care. All STI and STI related episodes were analysed. Results In total, 1 524 470 contacts of 375 899 registered persons in 104 practices were registered during 1 year and 2460 STI related episodes were found. The prevalence rate of STI was 39 per 10 000 persons and of STI/HIV related questions 23 per 10 000. More than half of all STIs were found in highly urbanised areas and STIs were overrepresented in deprived areas. Three quarters of all STIs diagnosed in the Netherlands are made in general practice. An important number of other reproductive health visits in general practice offer opportunities for meaningful STI counselling and tailored prevention. Discussion GPs contribute significantly to STI control, see the majority of patients with STI related symptoms and questions and are an important player in STI care. In particular, GPs in urban areas and inner-city practices should be targeted for accelerated sexual health programmes. PMID:16464323

    first statistical study of the relative orientation between the matter structures and the magnetic field in the ISM points out that, at the angular scales probed by Planck, the field geometry projected on the plane of the sky is correlated with the distribution of matter. In the diffuse ISM, the structures of matter are usually aligned with the magnetic field, while perpendicular structures appear in molecular clouds. We discuss our results in the context of models and MHD simulations, which attempt to describe the respective roles of turbulence, magnetic field, and self-gravity in the formation of structures in the magnetized ISM.

    Background The number of blood tests ordered in primary care continues to increase and the timely and appropriate communication of results remains essential. However, the testing and result communication process includes a number of participants in a variety of settings and is both complicated to manage and vulnerable to human error. In the UK, guidelines for the process are absent and research in this area is surprisingly scarce; so before we can begin to address potential areas of weakness there is a need to more precisely understand the strengths and weaknesses of current systems used by general practices and testing facilities. Methods We conducted a telephone survey of practices across England to determine the methods of managing the testing and result communication process. In order to gain insight into the perspectives from staff at a large hospital laboratory we conducted paired interviews with senior managers, which we used to inform a service blueprint demonstrating the interaction between practices and laboratories and identifying potential sources of delay and failure. Results Staff at 80% of practices reported that the default method for communicating normal results required patients to telephone the practice and 40% of practices required that patients also call for abnormal results. Over 80% had no fail-safe system for ensuring that results had been returned to the practice from laboratories; practices would otherwise only be aware that results were missing or delayed when patients requested results. Persistent sources of missing results were identified by laboratory staff and included sample handling, misidentification of samples and the inefficient system for collating and resending misdirected results. Conclusions The success of the current system relies on patients both to retrieve results and in so doing alert staff to missing and delayed results. Practices appear slow to adopt available technological solutions despite their potential for

  4. Control of gravitropic orientation. I. Non-vertical orientation by primary roots of maize results from decay of competence for orthogravitropic induction

    Plant organs may respond to gravity by vertical (orthogravitropic), oblique (plagiogravitropic) or horizontal (diagravitropic) growth. Primary roots of maize (Zea mays L.) provide a good system for studying such behaviours because they are reportedly capable of displaying all three responses. In current work using maize seedlings of the Silver Queen cultivar, stabilisation of growth at an oblique orientation was commonplace. Hypothetically, plagiogravitropism may be accomplished either by a process we call graded orthogravitropism or by hunting about a sensed non-vertical setpoint. In graded orthotropism primary bending is unidirectional and depends on facilitative stimuli that determine its extent. The hallmark of the setpoint mechanism is restorative curvature of either sign following a displacement; both diagravitropism and orthogravitropism are based on setpoints. Roots settled in a plagiogravitropic orientation were tested with various illumination and displacement protocols designed to distinguish between these two hypotheses. The tests refuted the setpoint hypothesis and supported that of graded orthotropism. No evidence of diagravitropism could be found, thus, earlier claims were likely based on inadequately controlled observations of graded orthotropism. We propose that orthotropism is graded by the sequential action of dual gravity receptors: induction of a vectorial gravitropic response requires gravitational induction of a separate facilitative response, whose decay in the absence of fresh stimuli can brake gravitropism at plagiotropic angles.

    A non-scientific poll of fellow practicing professionals suggests that there is a range of opinions regarding the effectiveness of different ways of becoming acquainted with and using the results of academic research in their practice. Journal articles remain the dominant path for transferring research results to the profession, even though accessing them is becoming more difficult with time. Driven primarily by cost considerations personal and corporate subscriptions seem to be on the decline. Libraries are one of the first victims of cost cutting measures in the industry. Even though the availability of journal articles in electronic form facilitates their availability, their prices are prohibitive. This is especially true during when a professional is searching for a solution to a problem and may have to review several papers on the subject. One colleague suggested that the professional organizations and other publishers of research articles could learn from the experience of the music industry, by lowering the cost of downloading individual papers to something like a dollar per article, recovering thus their production costs through the increase in the volume of purchased articles. The posting on the internet of special reports and dissertations by research institutions is viewed as very useful by those working in practice. The distribution through the internet of reports by federal organizations conducting or sponsoring research, such as the U.S. Geological Survey and the U.S. Environmental Protection Agency is greatly appreciated by the practicing professionals. The use of leading researchers as consultants provides a direct path for bringing research results to the practice, but it is limited to a small number of cases where bringing in a consultant can be justified. Short courses are viewed as an effective way of familiarizing professionals with the latest research findings on specific subjects. The notes distributed in such courses are considered

  6. Analyzing Orientations

    NASA Astrophysics Data System (ADS)

    Ruggles, Clive L. N.

    Archaeoastronomical field survey typically involves the measurement of structural orientations (i.e., orientations along and between built structures) in relation to the visible landscape and particularly the surrounding horizon. This chapter focuses on the process of analyzing the astronomical potential of oriented structures, whether in the field or as a desktop appraisal, with the aim of establishing the archaeoastronomical "facts". It does not address questions of data selection (see instead Chap. 25, "Best Practice for Evaluating the Astronomical Significance of Archaeological Sites", 10.1007/978-1-4614-6141-8_25) or interpretation (see Chap. 24, "Nature and Analysis of Material Evidence Relevant to Archaeoastronomy", 10.1007/978-1-4614-6141-8_22). The main necessity is to determine the azimuth, horizon altitude, and declination in the direction "indicated" by any structural orientation. Normally, there are a range of possibilities, reflecting the various errors and uncertainties in estimating the intended (or, at least, the constructed) orientation, and in more formal approaches an attempt is made to assign a probability distribution extending over a spread of declinations. These probability distributions can then be cumulated in order to visualize and analyze the combined data from several orientations, so as to identify any consistent astronomical associations that can then be correlated with the declinations of particular astronomical objects or phenomena at any era in the past. The whole process raises various procedural and methodological issues and does not proceed in isolation from the consideration of corroborative data, which is essential in order to develop viable cultural interpretations.

    Despite advances in lesbian, gay, bisexual and transgender equality in recent years, some men who have sex with men remain at increased risk of ill-health. Positive interventions in primary care include psychological support and strategies for risk reduction. It is important that men who have sex with men can disclose sexual orientation in primary care. To quantify disclosure of sexual orientation by men who have sex with men attending general practice and identify barriers to disclosure we surveyed a group of Scottish men. A questionnaire was distributed by voluntary organisations and the National Health Service in the West of Scotland, to rural and urban populations. Two hundred and four gave evaluable responses, with all ages represented. A total of 199 (98%) were registered with a General Practitioner and 167 (83%) attended in the previous year. A total of 81 (40%) stated staff were aware of their sexual orientation. A total of 93/121 (75%) men who have sex with men whose GP was unaware stated this was because they had never been asked. A total of 36/81(44%) men who have sex with men rated support from practices since disclosure as 'excellent' and qualitative responses were positive. It is reassuring that almost all respondents were registered with GPs and attending primary care services. However, only 40% had disclosed sexual orientation. This was not because of fear of negative impact on care but because men who have sex with men felt it was irrelevant to their attendance. GPs appear to be reluctant to raise the issue of sexual orientation without prompting. PMID:25527656

    Background. Yoga shows promise as a therapeutic intervention, but relationships between yoga practice and health are underexplored. Purpose. To examine the relationship between yoga practice and health (subjective well-being, diet, BMI, smoking, alcohol/caffeine consumption, sleep, fatigue, social support, mindfulness, and physical activity). Methods. Cross-sectional, anonymous internet surveys distributed to 4307 randomly selected from 18,160 individuals at 15 US Iyengar yoga studios; 1045 (24.3%) surveys completed. Results. Mean age 51.7 (± 11.7) years; 84.2% female. Frequency of home practice favorably predicted (P < .001): mindfulness, subjective well-being, BMI, fruit and vegetable consumption, vegetarian status, sleep, and fatigue. Each component of yoga practice (different categories of physical poses, breath work, meditation, philosophy study) predicted at least 1 health outcome (P < .05). Conclusions. Home practice of yoga predicted health better than years of practice or class frequency. Different physical poses and yoga techniques may have unique health benefits. PMID:22927885

    Controlled Ecological Life Support System (CELSS) technology is critical to the Space Exploration Initiative. NASA's Kennedy Space Center has been performing CELSS research for several years, developing data related to CELSS design. We have developed OCAM (Object-oriented CELSS Analysis and Modeling), a CELSS modeling tool, and have used this tool to evaluate CELSS concepts, using this data. In using OCAM, a CELSS is broken down into components, and each component is modeled as a combination of containers, converters, and gates which store, process, and exchange carbon, hydrogen, and oxygen on a daily basis. Multiple crops and plant types can be simulated. Resource recovery options modeled include combustion, leaching, enzyme treatment, aerobic or anaerobic digestion, and mushroom and fish growth. Results include printouts and time-history graphs of total system mass, biomass, carbon dioxide, and oxygen quantities; energy consumption; and manpower requirements. The contributions of mass, energy, and manpower to system cost have been analyzed to compare configurations and determine appropriate research directions.

    Despite powerful evidence that informal social support contributes to survivors' safety and well-being, mainstream domestic violence (DV) programs have not developed comprehensive models for helping isolated survivors re-engage with these networks. Although many advocates use network-oriented strategies informally, they often do so without resources, funding, or training. This qualitative focus group study explored advocates' use and perceptions of network-oriented strategies. Advocates working in a range of DV programs across one state described the importance of network-oriented work and articulated its five dimensions, including helping survivors build their capacity to form healthy relationships, identify helpful and harmful network members, re-engage with existing networks, develop new relationships, and respond more effectively to network members.

    1993-01-01

    Using the experimental data obtained with killed cells of Schizosaccharomyces pombe (1), we have formulated a theoretical model that is able to predict cell orientation for microorganisms with ellipsoidal or cylindrical shapes as a function of the frequency of the electric field and of the conductivity of the external medium. In this model, comparison of the difference in potential energy for both orientations parallel-perpendicular with the thermal agitation energy allows one to interpret the intervals where these orientations occur. The model implies that the conductivity of the cytoplasm is slightly higher than that of the external medium. This assumption is easy to understand taking into account that not all the intracytoplasmic material is released to the exterior during cell death. PMID:8324197

    Objective Opioid pharmacotherapy is now the leading treatment for chronic pain, a problem that affects nearly one-third of the United States population. Given the dramatic rise in prescription opioid misuse and opioid-related mortality, novel behavioral interventions are needed. The purpose of this study was to conduct an early stage randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE), a multimodal intervention designed to simultaneously target mechanisms underpinning chronic pain and opioid misuse. Method Chronic pain patients (N=115; mean age = 48±14; 68% female) were randomized to 8 weeks of MORE or a Support Group (SG). Outcomes were measured at pre- and post-treatment, and at 3-month follow-up. The Brief Pain Inventory assessed changes in pain severity and interference. Changes in opioid use disorder status were measured by the Current Opioid Misuse Measure. Desire for opioids, stress, nonreactivity, reinterpretation of pain sensations, and reappraisal were also evaluated. Results MORE participants reported significantly greater reductions in pain severity (p = .038) and interference (p = .003) than SG participants, which were maintained by 3-month follow-up and mediated by increased nonreactivity and reinterpretation of pain sensations. Compared with SG participants, participants in MORE evidenced significantly less stress arousal (p = .034) and desire for opioids (p = .027), and were significantly more likely to no longer meet criteria for opioid use disorder immediately following treatment (p = .05); however, these effects were not sustained at follow-up. Conclusions Findings demonstrate preliminary feasibility and efficacy of MORE as a treatment for co-occurring prescription opioid misuse and chronic pain. PMID:24491075

    1993-02-01

    This article, which is the first of a two-part series, presents results for the first objective of The American Dietetic Association (ADA) 1991 Dietetic Practice Study: to determine the characteristics of advanced-level dietetics practice. A nationwide mail survey of ADA members was conducted on a stratified random sample of 8,012 beyond-entry-level (registered before April 1988) registered dietitians who were members of dietetic practice groups (DPGs). The sample was supplemented with two randomly selected control groups of 1,000 entry-level and 1,000 beyond-entry-level registered dietitians. The overall response rate was 63.1%. The 5,852 usable returns were representative of the dietetics population surveyed. A model of advanced-level professional practice was developed that specified minimum necessary requirements for advanced practitioners on five components: education and experience, professional achievement, approach to practice, professional role positions, and professional role contacts; measurement of a sixth component, advanced-level practice performance, was unsuccessful. A series of validation analyses found the model to be a statistically sound and reliable means of distinguishing advanced practitioners from other groups of dietitians in 8 of every 10 cases. A total of 461 (8.9%) dietitians met all requirements of the model and were classified as advanced practitioners. Projected estimations of advanced practitioners in the population of beyond-entry-level ADA members who are also members of DPGs ranged between 2,126 and 2,640 dietitians (3.5% to 4.3% of the ADA membership).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8423288

    Practice-based research networks (PBRNs) create continuous collaborations among academic researchers and practitioners. Most PBRNs have operated in primary care, and less than 5% of federally registered PBRNs include mental health practitioners. In 2012 the first PBRN in the nation focused on individuals with serious mental illnesses-the Recovery-Oriented Care Collaborative-was established in Los Angeles. This column describes the development of this innovative PBRN through four phases: building an infrastructure, developing a research study, executing the study, and consolidating the PBRN. Key lessons learned are also described, such as the importance of actively engaging direct service providers and clients. PMID:26130004

    Sport plays an important role within society and sports stadia provide significant settings for public health strategies. In addition to being places of mass gathering, stadia are often located in less affluent areas and are traditionally attended by 'harder to reach' communities. Unfortunately sports stadia and the clubs they host are rarely perceived as places that promote healthy lifestyles. Fast food, alcohol and tobacco are commonly advertized, served and consumed during sports games giving the spectators and TV fans contradictory messages concerning healthy choices. As part of a wider programme of work part-funded by the European Union, a study was therefore designed to explore current 'good practice' relating to positive health interventions in sports stadia across a number of European countries. Using a specially designed questionnaire, information about health policies and good practices relating to food offerings in stadia, physical activity promotion among local communities, tobacco policy, positive mental health initiatives, environmental sustainability practices and social responsibility policies were collected in 10 European countries (England and Northern Ireland, Finland, Georgia, Greece, Ireland, Italy, Latvia, Poland, Spain and Sweden) involving 88 stadia. The audit results show that stadia health policies differ considerably between specific countries and sports. Based on the literature analysed, the examples of good practices collected through the study, and the subsequent instigation of a European Healthy Stadia Network, it shows that there is considerable potential for stadia to become health promoting settings.

    In our opinion German gynaecology has failed to adequately face what came to pass during the Nazi period. This can be proved objectively, for there is no evidence that, after 1945, gynaecology had in any way cared to take notice--either thermatically or medically--of the thousands of victims of inhuman practices such as forced termination of pregnancy, compulsory sterilisation and the like. During the past 50 years recollections of enforced sterilisations, compulsory abortions, deliberate and hence criminal negligence and problematic approaches in research and teaching were almost completely banished from the area of conscious awareness and largely suppressed or silently ignored. Most of the medical directors of Departments of Gynaecology of German universities shared this view whenever they were questioned on the connections between gynaecology and Nazism. Now that two generations have passed it seems possible to examine and explore with less guilt feelings and shame the immensely fateful rôle of gynaecology in that context. Accent should be on the fate of the victims of that period. To bring back these events to memory, however, does not permit to conceal the part played by the physicians committing of these inhuman Nazi crimes. Data collected from a psychosomatically oriented examination of victims exemplify that to concretely recall gynaecology during Nazism a1-so offers a chance in several respects. One of the possibilities in this context is to signal "late apology" and regret to patients who had been victims, in one's own area of work, after one has psychically worked over their fate. Besides, a gynaecological-psychosomatic expertise will help e.g. that compulsorily sterilised women are granted financial aid that has at long last become a legal possibility and can be applied for since 1980. However, the relevant patient records do show very clearly that the inhuman practice of gynaecology during the so-called "Third Reich" was not only a collective problem

    Objective To examine the mediating effect of childhood abuse on sexual orientation disparities in tobacco and alcohol use during adolescence. Methods We carried out analyses with data from over 62,000 women in the ongoing Nurses’ Health Study II cohort who provided information on sexual orientation, childhood abuse occurring by age 11, and tobacco and alcohol use in adolescence. We used multivariate regression analyses, controlling for confounders, to estimate the mediating effect of childhood abuse on the association between sexual orientation and tobacco and alcohol use in adolescence. Results Lesbian and bisexual orientation and childhood abuse were positively associated with greater risk of tobacco and alcohol use during adolescence. For lesbians, the estimated proportion of excess tobacco and alcohol use in adolescence relative to use among heterosexual women that was mediated by abuse in childhood ranged from 7 to 18%; for bisexual women, the estimated proportion of excess use mediated by abuse ranged from 6 to 13%. Conclusions Elevated childhood abuse in lesbian and bisexual women partially mediated excess tobacco and alcohol use in adolescence relative to heterosexual women. Interventions to prevent child abuse may reduce sexual orientation disparities in some of the leading causes of cancer in women. PMID:20640883

    Meditation and spiritual practices are conceptually similar, eliciting similar subjective experiences, and both appear to provide similar benefits to the practicing individuals. However, no research has examined whether the mechanism of action leading to the beneficial effects is similar in both practices. This review examines the neuroimaging research that has focused on groups of meditating individuals, groups who engage in religious/spiritual practices, and research that has examined groups who perform both practices together, in an attempt to assess whether this may be the case. Differences in the balance of activity between the parietal and prefrontal cortical activation were found between the three groups. A relative prefrontal increase was reflective of mindfulness, which related to decreased anxiety and improved well-being. A relative decrease in activation of the parietal cortex, specifically the inferior parietal cortex, appears to be reflective of spiritual belief, whether within the context of meditation or not. Because mindful and spiritual practices differ in focus regarding the 'self' or 'other' (higher being), these observations about neurological components that reflect spirituality may continue work towards understanding how the definition of 'self' and 'other' is represented in the brain, and how this may be reflected in behaviour. Future research can begin to use cohorts of participants in mindfulness studies which are controlled for using the variable of spirituality to explicitly examine how functional and structural similarities and differences may arise.

    Not only climate change affects hydrological systems but also land use change and agricultural tillage practises have an important impact on infiltration and runoff generation. In the last five to six decades monocropping, drainage and rectification of small rivers were carried out to optimize crop yields and economic benefits. However, in recent years more holistic and sustainable management concepts are required. The advantages of ecological management of land, soil and water resources are manifold: the biodiversity is higher, the buffer function of soils will be conserved and both low water and floods are positive affected. The target of the presented research project which is financed by the Bavarian environment agency, is to establish an optimal flood retention concept in a mesoscale catchment of 150 km² which emphasizes ecological flood measures like best tillage practices, small retention basins and renaturation of small rivers. To quantify the effects of these measures the water balance model WaSiM-ETH was used. The grid-based water flow and balance simulation model WaSiM-ETH is a well-established tool for investigating the spatial and temporal variability of hydrological processes in complex river basins. The model can be seen as a reasonable compromise between detailed physical basis and minimum data requirements (http://www.wasim.ch/en/index.html). WaSiM was coupled with a 2d-ground water model and an additional drainage tool. Different vegetation was parameterized with high spatial and temporal resolution. Additionally, future climate scenarios like the extension of vegetation periods were considered. The effectiveness of decentralized retention basins could be simulated by a new implemented see storage tool. The presentation will give quantitative results for different flood control measures. The pros and cons of physically based approaches in hydrological modelling will be discussed.

    Correctional nursing has been recognized as a specialty since 1985, but research to describe and support nursing practice in the criminal justice system has been sparse. The development of a research agenda can stimulate the research necessary to provide an evidence base for specialty practice development. A three-round Delphi study was undertaken to elicit a prioritized list of research topics to guide future research efforts for meaningful results. Six predominant themes emerged from an analysis of top research questions generated by a panel of 18 correctional nursing experts. Research priorities include critical thinking and clinical judgment, competency and educational level, assessment, nursing protocols, effect on patient outcomes, and the environment of care.

    At present, it appears to be probable that both dietary changes and medicinal treatment can reduce the risk of development of coronary disease in middle-aged men with moderately to severely raised blood cholesterol values. Internationally, the limits for cholesterol intervention are considerably lower than in Denmark. Extensive cholesterol screening is, however, very expensive and the identified persons with high cholesterol values will frequently be found in sex and age groups where the beneficial effect of intervention is probably limited. A model for selective cholesterol screening in high risk groups in general practice is described here. In 20 general practices, all of the men aged 45-59 years belonging to the practice were invited to examination of cholesterol and blood pressure. Plasma cholesterol was measured by means of a Reflotron (results are available within three minutes) and the blood pressure and tobacco consumption were registered. After this, the patient's own general practitioner calculated with each of the persons the risk for development of myocardial infarction within the next ten years and intervention could be commenced immediately. 41% of those invited came for examination. Out of these, 29% had cholesterol values greater than or equal to 7.0 mmol/l (Danish limiting value), 44% greater than or equal to 6.5 mmol/l (limiting value in the remainder of Western Europe), and 5% greater than or equal to 9.0 mmol/l (severe hypercholesterolaemia) while only 18% had completely normal cholesterol less than 5.2 mmol/l. In every practice, two patients on an average were found with severe hypercholesterolaemia greater than or equal to 9.0 mmol/l. 28% of the participants had at least two of the three risk factors investigated.

    2011-01-01

    Background Substance use and poor dietary practices are prevalent among adolescents. The purpose of this study was to examine frequency of substance use and associations between cigarette, alcohol and marijuana use and selected dietary practices, such as sugar-sweetened beverages, high-fat foods, fruits and vegetables, and frequency of fast food restaurant use among alternative high school students. Associations between multi-substance use and the same dietary practices were also examined. Methods A convenience sample of adolescents (n = 145; 61% minority, 52% male) attending six alternative high schools in the St Paul/Minneapolis metropolitan area completed baseline surveys. Students were participants in the Team COOL (Controlling Overweight and Obesity for Life) pilot study, a group randomized obesity prevention pilot trial. Mixed model multivariate analyses procedures were used to assess associations of interest. Results Daily cigarette smoking was reported by 36% of students. Cigarette smoking was positively associated with consumption of regular soda (p = 0.019), high-fat foods (p = 0.037), and fast food restaurant use (p = 0.002). Alcohol (p = 0.005) and marijuana use (p = 0.035) were positively associated with high-fat food intake. With increasing numbers of substances, a positive trend was observed in high-fat food intake (p = 0.0003). There were no significant associations between substance use and fruit and vegetable intake. Conclusions Alternative high school students who use individual substances as well as multiple substances may be at high risk of unhealthful dietary practices. Comprehensive health interventions in alternative high schools have the potential of reducing health-compromising behaviors that are prevalent among this group of students. This study adds to the limited research examining substance use and diet among at-risk youth. Trial registration number ClinicalTrials.gov: NCT01315743 PMID:21518437

  14. A method for obtaining practical flutter-suppression control laws using results of optimal control theory

    1979-01-01

    The results of optimal control theory are used to synthesize a feedback filter. The feedback filter is used to force the output of the filtered frequency response to match that of a desired optimal frequency response over a finite frequency range. This matching is accomplished by employing a nonlinear programing algorithm to search for the coefficients of the feedback filter that minimize the error between the optimal frequency response and the filtered frequency response. The method is applied to the synthesis of an active flutter-suppression control law for an aeroelastic wind-tunnel model. It is shown that the resulting control law suppresses flutter over a wide range of subsonic Mach numbers. This is a promising method for synthesizing practical control laws using the results of optimal control theory.

    Background One of the greatest challenges facing health promotion and disease prevention is translating research findings into evidence-based practices (EBP). There is currently a limited research base to inform the design of dissemination action plans, especially within medically underserved communities. Objective The objective of this paper is to describe an innovative study protocol to disseminate colorectal cancer (CRC) screening guidelines in seven Asian subgroups. Methods This study integrated a market-oriented Push-Pull-Infrastructure Model, Diffusion of Innovation Theory, and community-based participatory research approach to create a community-centered dissemination framework. Consumer research, through focus groups and community-wide surveys, was centered on the adopters to ensure a multilevel intervention was well designed and effective. Results Collaboration took place between an academic institution and eight community-based organizations. These groups worked together to conduct thorough consumer research. A sample of 72 Asian Americans participated in 8 focus groups, and differences were noted across ethnic groups. Furthermore, 464 community members participated in an Individual Client Survey. Most participants agreed that early detection of cancer was important (434/464, 93.5%), cancer could happen to anyone (403/464, 86.9%), CRC could be prevented (344/464, 74.1%), and everyone should screen for CRC (389/464, 83.8%). However, 35.8% (166/464) of participants also felt that people were better off not knowing it they had cancer, and 45.5% (211/464) would screen only when they had symptoms. Most participants indicated that they would screen upon their doctor’s recommendation, but half reported that they only saw a doctor when they were sick. Data collection currently is underway for a multilevel intervention (community health advisor and social marketing campaign) and will conclude March 2016. We expect that analysis and results will be available by

    The Clinical Decision Support Consortium has completed two demonstration trials involving a web service for the execution of clinical decision support (CDS) rules in one or more electronic health record (EHR) systems. The initial trial ran in a local EHR at Partners HealthCare. A second EHR site, associated with Wishard Memorial Hospital, Indianapolis, IN, was added in the second trial. Data were gathered during each 6 month period and analyzed to assess performance, reliability, and response time in the form of means and standard deviations for all technical components of the service, including assembling and preparation of input data. The mean service call time for each period was just over 2 seconds. In this paper we report on the findings and analysis to date while describing the areas for further analysis and optimization as we continue to expand our use of a Services Oriented Architecture approach for CDS across multiple institutions.

    2014-01-01

    In this paper, a physical method to obtain control-oriented dynamical models of large scale cryogenic refrigerators is proposed, in order to synthesize model-based advanced control schemes. These schemes aim to replace classical user experience designed approaches usually based on many independent PI controllers. This is particularly useful in the case where cryoplants are submitted to large pulsed thermal loads, expected to take place in the cryogenic cooling systems of future fusion reactors such as the International Thermonuclear Experimental Reactor (ITER) or the Japan Torus-60 Super Advanced Fusion Experiment (JT-60SA). Advanced control schemes lead to a better perturbation immunity and rejection, to offer a safer utilization of cryoplants. The paper gives details on how basic components used in the field of large scale helium refrigeration (especially those present on the 400W @1.8K helium test facility at CEA-Grenoble) are modeled and assembled to obtain the complete dynamic description of controllable subsystems of the refrigerator (controllable subsystems are namely the Joule-Thompson Cycle, the Brayton Cycle, the Liquid Nitrogen Precooling Unit and the Warm Compression Station). The complete 400W @1.8K (in the 400W @4.4K configuration) helium test facility model is then validated against experimental data and the optimal control of both the Joule-Thompson valve and the turbine valve is proposed, to stabilize the plant under highly variable thermals loads.

    Dissolved organic carbon (DOC) fluxes are recently increasing in surface waters of humid climate regions. Due to its substantial importance for leaching processes, aquatic foodwebs, and drinking water purification a better understanding of sources and pathways of DOC is needed. Therefore this study aims to analyse and simulate DOC fluxes in agricultural ecosystems with selected crop rotations. A data set of 24 lysimeters of the UFZ Lysimeter station at Falkenberg (Saxony-Anhalt) covering nine years of DOC investigation has been selected and examined. The data set covers a wide range of climatic conditions with deviating management practices for grasslands and agricultural crop rotations. The monthly DOC concentrations assessed in the leached water range from 2.4 to 34.1 mg /l. DOC concentrations depend on temperature, precipitation and discharge. The type of crop grown on the lysimeter is an important trigger for DOC leaching - especially lysimeters used as pasture, or planted with rape and carrots exhibit high DOC concentrations. Management practices and fertilizer application modify the leaching of DOC and offer potentials to reduce DOC losses. The results form the basis of further process simulation studies and upscaling of the results to the small catchment scale.

    An overview of the conception and development of the MIDAS system at Arizona State University is given: a Microscope for Imaging, Diffraction and Analysis of Surfaces. John Cowley's vision in the early 1980s was ambitious and far-reaching, and it was because of him the authors came to ASU. We were centrally involved in the design and implementation of MIDAS from the mid 1980s onwards; the novel design features are briefly reviewed. Practical results obtained using this instrument are listed, and the scope for future development and applications are indicated. While it is clear that many new results have been demonstrated, even more possibilities still remain to be explored. Some comments are made about the feasibility of such developments in the light of competing instrumentation. PMID:16123069

    Guidelines were introduced in hospital and practice-based otorhinolaryngology in the 1990s, and have been undergoing further development ever since. There are currently 20 guidelines on file at the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery. The Society has cooperated in a further 34 guidelines. The quality of the guidelines has been continually improved by concrete specifications put forward by the Association of the Scientific Medical Societies in Germany [Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e.V.]. Since increasing digitalisation has made access to scientific publications quicker and more simple, relevant study results can be incorporated in guidelines more easily today than in the analogue world. S2e and S3 guidelines must be based on a formal literature search with subsequent evaluation of the evidence. The consensus procedure for S2k guidelines is also regulated. However, the implementation of guidelines in routine medical practice must still be considered inadequate, and there is still a considerable need for improvement in adherence to these guidelines.

    Repository-oriented leaching experiments involving Savannah River Laboratory (SRL) 165 type glass under a {gamma}-radiation field (1 = 0.2 x 10{sup 4} R/h) have been performed by the Nevada Nuclear Waste Storage Investigations (NNWSI) project. In this communication, we discuss glass surface analyses obtained by SEM, nuclear resonance profiling, and SIMS together with leachate solution data in relation to a mechanism that couples diffusion, hydrolysis (etching and gelation), and precipitation to qualitatively describe the release of different glass components to the leachant solutions. The release of mobile (e.g., Li) and partly mobile (e.g., B) species is controlled primarily by interdiffusion with water species across the interdiffusion zone. Glass components that are immobile in the interdiffusion zone are released to the solution by etching. For prediction of long-term steady-state concentrations of glass components with low solubility, the relative rates of release from the glass and secondary mineral precipitation must be taken into account.

    This prospective, mixed-methods study investigated how the nature of joint activities between volunteer mentors and student mentees corresponded to relationship quality and youth outcomes. Focusing on relationships in school-based mentoring programs in low-income urban elementary schools, data were obtained through pre-post assessments, naturalistic observations, and in-depth interviews with mentors and mentees. Adopting an exploratory approach, the study employed qualitative case study methods to inductively identify distinctive patterns reflecting the focus of mentoring activities. The activity orientations of relationships were categorized according to the primary functional role embodied by the mentor and the general theme of interactions: teaching assistant/tutoring, friend/engaging, sage/counseling, acquaintance/floundering. Next, these categories were corroborated by comparing the groups on quantitative assessments of relationship quality and change in child outcomes over time. Relationships characterized by sage mentoring, which balanced amicable engagement with adult guidance, were rated most favorably by mentees on multiple measures of relationship quality. Furthermore, students involved in sage mentoring relationships showed declines in depressive symptoms and aggressive behaviors. For disconnected pairs (acquaintances), students reported more negative relationship experiences. Findings suggest effective mentoring relationships represent a hybrid between the friendly mutuality of horizontal relationships and the differential influence of vertical relationships.

    Although parent education after separation in Canada is relatively new, most provinces and territories now have some type of program that provides separating parents with information on their children's needs, co-parenting options, and strategies for improving communication. A 1999-2000 survey of parents in 10 such program sites throughout Canada: (a) demonstrates a high level of parent satisfaction with the programs, (b) chronicles benefits related to reduced conflict and improved child well-being 3 to 4 months following program attendance, and (c) identifies several implications for best practices. Results of this study suggest that parent education is but one program within a network of services needed to support both parents and children after separation. PMID:14664107

    Background On the range of diagnoses, course of treatment, and long-term outcome in patients who chose to receive homeopathic medical treatment very little is known. We investigated homeopathic practice in an industrialized country under everyday conditions. Methods In a prospective, multicentre cohort study with 103 primary care practices with additional specialisation in homeopathy in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: Patient and physician assessments (numeric rating scales from 0 to 10) and quality of life at baseline, and after 3, 12, and 24 months. Results A total of 3,981 patients were studied including 2,851 adults (29% men, mean age 42.5 ± 13.1 years; 71% women, 39.9 ± 12.4 years) and 1,130 children (52% boys, 6.5 ± 3.9 years; 48% girls, 7.0 ± 4.3 years). Ninety-seven percent of all diagnoses were chronic with an average duration of 8.8 ± 8 years. The most frequent diagnoses were allergic rhinitis in men, headache in women, and atopic dermatitis in children. Disease severity decreased significantly (p < 0.001) between baseline and 24 months (adults from 6.2 ± 1.7 to 3.0 ± 2.2; children from 6.1 ± 1.8 to 2.2 ± 1.9). Physicians' assessments yielded similar results. For adults and young children, major improvements were observed for quality of life, whereas no changes were seen in adolescents. Younger age and more severe disease at baseline were factors predictive of better therapeutic success. Conclusion Disease severity and quality of life demonstrated marked and sustained improvements following homeopathic treatment period. Our findings indicate that homeopathic medical therapy may play a beneficial role in the long-term care of patients with chronic diseases. PMID:16266440

Final results based on the full study sample (full data available February 1998) details of payor costs such as provider, facility, NICU, and ancillary along with costs from the health care system perspective and patient satisfaction results will be presented.Conclusion: Current results suggest similar morbidity and mortality between the birth center program and traditional care groups, with less resource utilization translating to lower costs in the collaborative practice model. Results suggest that collaborative practice using a freestanding birth center as an adjunct to an integrated perinatal health care system may provide a quality, lower-cost alternative for the provision of perinatal services.

    We compared the clinical trial transparency practices of US/European pharma by analyzing the publicly-accessible clinical trial results databases of major drugs (doripenem, varenicline, lapatinib, zoledronic acid, adalimumab, insulin glargine, raltegravir, gefitinib). We evaluated their accessibility and utility from the perspective of the lay public. We included databases on company websites, http://www.clinicalstudyresults.org, http://www.clinicaltrials.gov and http://clinicaltrials.ifpma.org. Only 2 of 8 company homepages provide a direct link to the results. While the use of common terms on company search engines led to results for 5 of the 8 drugs following 2-4 clicks, no logical pathway was identified. The number of clinical trials in the databases was inconsistent: 0 for doripenem to 45 for insulin glargine. Results from all phases of clinical development were provided for 2 (insulin glargine and gefitinib) of the 8 drugs. Analyses of phase III reports revealed that most critical elements of the International Conference of Harmonization E3 Structure and Content of Synopses for Clinical Trial Reports were provided for 2 (varenicline, lapatinib) of the 8 drugs. For adalimumab and zoledronic acid, only citations were provided, which the lay public would be unable to access. None of the clinical trial reports was written in lay language. User-friendly support, when provided, was of marginal benefit. Only 1 of the databases (gefitinib) permitted the user to find the most recently updated reports. None of the glossaries included explanations for adverse events or statistical methodology. In conclusion, our study indicates that the public faces significant hurdles in finding and understanding clinical trial results databases. PMID:19348964

    Practice refers to a characteristic way professionals use common standards to customize solutions to a range of problems. Practice includes (a) standards for outcomes and processes that are shared with one's colleagues, (b) a rich repertoire of skills grounded in diagnostic acumen, (c) an ability to see the actual and the ideal and work back and forth between them, (d) functional artistry, and (e) learning by doing that transcends scientific rationality. Communities of practice, such as dental offices, are small groups that work together in interlocking roles to achieve these ends. PMID:19413050

    1990-05-01

    A national survey of over 300 commercial design architects was conducted to develop baseline information on their knowledge, perceptions, and use of daylighting in commercial building designs. Pacific Northwest Laboratory conducted the survey for the US Department of Energy's (DOE) Office of Building and Community Systems (BCS). In the survey daylighting was defined as the intentional use of natural light as a partial substitute for artificially generated light. The results suggested that architects need to be educated about the true benefits of daylighting and the impacts it can have on a building's energy performance. Educational programs that will increase the architects' understanding and awareness of modern daylighting technologies and practices should be developed by utilities, stage agencies, and the federal government. If more architects can be made aware of the true effectiveness and positive attributes of daylighting systems and technologies, daylighting may be used in more commercial buildings. The results of the survey show that the more familiar architects feel they are with daylighting, the more they use daylighting. 3 refs., 19 tabs.

    Evidence-based practice is currently one of the most important developments in health care. Research in nursing science is rapidly growing; however, translating the knowledge based on this research into clinical practice is often hampered, and may be dependent on reflective skills. The aim of this study was to see how undergraduate nursing students in nursing should increase their skills and knowledge related to evidence-based practice through participation in clinical research projects. A qualitative approach was used in collecting and analyzing the data. Students participated in a pilot clinical research project and a received guidance related to their bachelor thesis. After the project was completed, all students filled in a questionnaire. The students' motivation to participate in this study was reported to be high, but they reported low knowledge related to evidence-based practice. All students reported that their attitude towards evidence-based practice changed in a positive direction during their participation in the project. Evidence-based practice influenced nursing practices by putting more focus on critical thinking, increasing pride and giving a sense of ownership in the clinical field. The curricula and the pedagogical perspectives in nursing education can influence the attitude towards evidence-based practice and skills among nursing bachelor students. PMID:27235563

    Zha, Z.; Zhou, X.

    2011-08-01

    Based on the analysis and research on the current geographic information sharing and metadata service,we design, develop and deploy a distributed metadata service system based on GeoNetwork covering more than 30 nodes in provincial units of China.. By identifying the advantages of GeoNetwork, we design a distributed metadata service system of national surveying and mapping results. It consists of 31 network nodes, a central node and a portal. Network nodes are the direct system metadata source, and are distributed arround the country. Each network node maintains a metadata service system, responsible for metadata uploading and management. The central node harvests metadata from network nodes using OGC CSW 2.0.2 standard interface. The portal shows all metadata in the central node, provides users with a variety of methods and interface for metadata search or querying. It also provides management capabilities on connecting the central node and the network nodes together. There are defects with GeoNetwork too. Accordingly, we made improvement and optimization on big-amount metadata uploading, synchronization and concurrent access. For metadata uploading and synchronization, by carefully analysis the database and index operation logs, we successfully avoid the performance bottlenecks. And with a batch operation and dynamic memory management solution, data throughput and system performance are significantly improved; For concurrent access, , through a request coding and results cache solution, query performance is greatly improved. To smoothly respond to huge concurrent requests, a web cluster solution is deployed. This paper also gives an experiment analysis and compares the system performance before and after improvement and optimization. Design and practical results have been applied in national metadata service system of surveying and mapping results. It proved that the improved GeoNetwork service architecture can effectively adaptive for distributed deployment

    BACKGROUND AND OBJECTIVES: Riyadh and central province falls in a moderate prevalent zone of hemoglobinopathies in Saudi Arabia. However, it has been observed that the physicians working in Saudi Arabia invariably advise all cases of anemia for hemoglobin electrophoresis (HE). The present work was carried out to study the yield of the HE in Riyadh and the investigative practices of the physicians advising HE. SETTINGS AND DESIGN: The study was carried out in the hospitals of King Saud University from 2009 to 2011 in order to assess the yield of HE in referred cases of clinical anemia. MATERIALS AND METHODS: A total of 1073 cases divided in two groups of males and females had undergone complete blood count and red blood cell morphology. Cellulose acetate HE was performed and all the positive results were reconfirmed on the high performance liquid chromatography (HPLC). The results were analyzed for the type of hemoglobinopathies. For statistical analysis Statistical Package for Social Sciences 15 version (SPSS Inc., Chicago, IL, USA) was used. RESULTS: A total of 405 males and 668 females blood samples were included in the present study. 116 (28.5%) males and 167 (25%) females showed an abnormal pattern on HE. The incidence of beta thalassemia trait was higher in females while sickle cell trait was predominantly seen in males. Red cell indices were reduced considerably in thalassemias, but were unaffected in sickle cell disorders, except those which had concurrent alpha trait. The total yield of HE was 26.6% which was much less than expected. CONCLUSION: The physicians are advised to rule out iron deficiency and other common causes of anemia before investigating the cases for hemoglobinopathies, which employs time consuming and expensive tests of HE and HPLC.

    Following a meta-analysis of test accuracy studies, the translation of summary results into clinical practice is potentially problematic. The sensitivity, specificity and positive (PPV) and negative (NPV) predictive values of a test may differ substantially from the average meta-analysis findings, because of heterogeneity. Clinicians thus need more guidance: given the meta-analysis, is a test likely to be useful in new populations, and if so, how should test results inform the probability of existing disease (for a diagnostic test) or future adverse outcome (for a prognostic test)? We propose ways to address this. Firstly, following a meta-analysis, we suggest deriving prediction intervals and probability statements about the potential accuracy of a test in a new population. Secondly, we suggest strategies on how clinicians should derive post-test probabilities (PPV and NPV) in a new population based on existing meta-analysis results and propose a cross-validation approach for examining and comparing their calibration performance. Application is made to two clinical examples. In the first example, the joint probability that both sensitivity and specificity will be >80% in a new population is just 0.19, because of a low sensitivity. However, the summary PPV of 0.97 is high and calibrates well in new populations, with a probability of 0.78 that the true PPV will be at least 0.95. In the second example, post-test probabilities calibrate better when tailored to the prevalence in the new population, with cross-validation revealing a probability of 0.97 that the observed NPV will be within 10% of the predicted NPV.

    2003-09-24

    Within the U.S. Department of Energy (DOE), the Office of Energy Efficiency and Renewable Energy (EERE) has a vision of a future with clean, abundant, reliable, and affordable energy. Within EERE, the Industrial Technologies Program (ITP), formerly the Office of Industrial Technologies, works in partnership with industry to increase energy efficiency, improve environmental performance, and boost productivity. The BestPractices (BP) Program, within ITP, works directly with industries to encourage energy efficiency. The purpose of the BP Program is to improve energy utilization and management practices in the industrial sector. The program targets distinct technology areas, including pumps, process heating, steam, compressed air, motors, and insulation. This targeting is accomplished with a variety of delivery channels, such as computer software, printed publications, Internet-based resources, technical training, technical assessments, and other technical assistance. A team of program evaluators from Oak Ridge National Laboratory (ORNL) was tasked to evaluate the fiscal year 2002 (FY02) energy savings of the program. The ORNL assessment enumerates levels of program activity for technology areas across delivery channels. In addition, several mechanisms that target multiple technology areas--e.g., Plant-wide Assessments (PWAs), the ''Energy Matters'' newsletter, and special events--are also evaluated for their impacts. When possible, the assessment relies on published reports and the Industrial Assessment Center (IAC) database for estimates of energy savings that result from particular actions. Data were also provided by ORNL, Lawrence Berkeley National Laboratory (LBNL) and Project Performance Corporation (PPC), the ITP Clearinghouse at Washington State University, the National Renewable Energy Laboratory (NREL), Energetics Inc., and the Industrial Technologies Program Office. The estimated energy savings in FY02 resulting from activities of the BP Program are almost

    The paper will describe two manned flights made in polyethylene zero pressure balloons with liquid helium carried to provide all in-flight buoyancy adjustment. These balloons were of 1,600 and 8,000 cubic meter volumes. Two flights have been made, both lasting 24 hours. The first flight cruised and flew through the sunset at 18,000 feet / 5,500 meters. The second flight using a pressurized cabin included flying through the night at about 32,000 feet / 10,000 meters. These flights highlight a wide range of theoretical and practical design concerns. For a craft carrying a crew, structural integrity and manageability &control in flight are naturally important. These flights demonstrated the complete feasibility of this system which will be described in detail. In addition the author constructed a 1,600 cubic meter pumpkin balloon used for a two day fight across Australia with a crew of two. Considerable problems were discovered during construction with distortion of the balloon. Although this work was done some time ago, the results have not been published in detail. The reason for publications at this time is that the work is very relevant to the problems recently encountered with the ULDB pumpkin design. The author, who is a physicist as well as a member of the Society of Experimental Test Pilots, was the principal desig ner as well as pilot of these craft. Ends...

    In connection with a screening investigation for high blood cholesterol in middle-aged men in general practice in the Municipality of Copenhagen, all participants with cholesterol values greater than or equal to 7.5 mmol/l were given brief advice by their own general practitioner and were invited to come for fasting blood lipid tests approximately ten days later. In cases with continued cholesterol greater than or equal to 6.8 mmol/l, the participants together with wives or partners were invited to formalized dietary advice in small groups. Already before the formalized dietary advice, an average decrease in serum cholesterol of 10% was observed. This was attributed to biological variation, absence of fasting, the degree of error between the measuring methods and also a genuine decrease on the basis of the brief dietary advice by the general practitioner. On control after dietary advice, a further decrease in cholesterol of 15% was observed while low density lipoprotein cholesterol fell by 20% and triglycerides by 23%. These decreases must be considered to result mainly from the dietary advice. It is concluded that a single but professional session of dietary advice in small groups and with involvement of the wives or partners is an effective method of treatment in hypercholesterolaemia. If the decrease in cholesterol obtained can be maintained, the literature suggests that the risk of development of ischaemic heart disease during the subsequent 5-7 years is reduced by 20-30%.

    Objective The pelvic floor is an integrated structure; dysfunctions may lead to a wide range of symptoms, involving voiding, defecation and sexual functioning (SF). Functional symptoms such as constipation and lower abdominal pain are often caused by pelvic floor dysfunction (PFD), and they highly impact the quality of life. Multiple specialists are responsible for a specific part of the pelvic floor, but its treatment asks for a holistic approach. The authors are still unaware of gastroenterologists' knowledge on PFD or whether they are addressing pelvic floor complaints in their daily practice. Design A 42-itemed anonymous questionnaire was mailed to all 402 members of the Dutch Society of Gastroenterology (gastroenterologists and residents-in-training). Results 169 (42%) questionnaires were analysed. Most gastroenterologists address lower urinary tract symptoms in their history-taking, 92% in female patients and 84% in male patients. When patients indicate irritable bowel syndrome-like complaints, more than 60% of the physicians inquire about SF to their female patients, compared with 38% inquiries to male patients (p<0.001). A reason not to inquire about SF is a lack of knowledge about female and male sexuality (19% and 23%, respectively). Forty-six per cent of the respondents regard it rather important to receive more training on PFD in male patients versus 61% in female patients. Conclusion Awareness of PFD is not yet routinely integrated into the history taken by gastroenterologists. PMID:24124626

    2015-08-01

    Maca, Lepidium meyenii Walpers (Brassicaceae), is an annual herbaceous plant native to the high plateaus of the Peruvian central Andes. Its underground storage hypocotyls have been a traditional medicinal agent and dietary staple since pre-Columbian times. Reported properties include energizing and fertility-enhancing effects. Published reports have focused on the benzylalkamides (macamides) present in dry hypocotyls as one of the main bioactive components. Macamides are secondary amides formed by benzylamine and a fatty acid moiety, with varying hydrocarbon chain lengths and degree of unsaturation. Although it has been assumed that they are usually present in fresh undamaged tissues, analyses show them to be essentially absent from them. However, hypocotyls dried by traditional Andean postharvest practices or industrial oven drying contain up to 800μgg(-1) dry wt (2.3μmolg(-1) dry wt) of macamides. In this study, the generation of macamides and their putative precursors were studied during nine-week traditional drying trials at 4200m altitude and in ovens under laboratory conditions. Freeze-thaw cycles in the open field during drying result in tissue maceration and release of free fatty acids from storage and membrane lipids up to levels of 1200μgg(-1) dry wt (4.3μmolg(-1) dry wt). Endogenous metabolism of the isothiocyanates generated from glucosinolate hydrolysis during drying results in maximal benzylamine values of 4300μgg(-1) dry wt (40.2μmolg(-1) dry wt). Pearson correlation coefficients of the accumulation profiles of benzylamine and free fatty acid to that of macamides showed good values of 0.898 and 0.934, respectively, suggesting that both provide sufficient substrate for amide synthesis during the drying process.

  9. Foreign exam management in practice: seamless access to foreign images and results in a regional environment.

    2015-04-01

    A challenge for many clinical users is that a patient may receive a diagnostic imaging (DI) service at a number of hospitals or private imaging clinics. The DI services that patients receive at other locations could be clinically relevant to current treatments, but typically, there is no seamless method for a clinical user to access longitudinal DI results for their patient. Radiologists, and other specialists that are intensive users of image data, require seamless ingestion of foreign exams into the picture archiving and communication system (PACS) to achieve full clinical value. Most commonly, a clinical user will depend on the patient to bring in a CD that contains imaging from another location. However, a number of issues can arise when using this type of solution. Firstly, a CD will not provide the clinical user with the full longitudinal record of the patient. Secondly, a CD often will not contain the report associated with the images. Finally, a CD is not seamless, due to the need to manually import the contents of the CD into the local PACS. In order to overcome these limitations, and provide clinical users with a greater benefit related to a patient's longitudinal DI history, the implementation of foreign exam management (FEM) at the local site level is required. This paper presents the experiences of FEM in practice. By leveraging industry standards and edge devices to support FEM, multiple sites with disparate PACS and radiology information system (RIS) vendors are able to seamlessly ingest foreign exams within their local PACS as if they are local exams.

    Background: older people often experience complex problems. Because of multiple problems, care for older people in general practice needs to shift from a ‘problem-based, disease-oriented’ care aiming at improvement of outcomes per disease to a ‘goal-oriented care’, aiming at improvement of functioning and personal quality of life, integrating all healthcare providers. Feasibility and cost-effectiveness of this proactive and integrated way of working are not yet established. Design: cluster randomised trial. Participants: all persons aged ≥75 in 59 general practices (30 intervention, 29 control), with a combination of problems, as identified with a structured postal questionnaire with 21 questions on four health domains. Intervention: for participants with problems on ≥3 domains, general practitioners (GPs) made an integrated care plan using a functional geriatric approach. Control practices: care as usual. Outcome measures: (i) quality of life (QoL), (ii) activities of daily living, (iii) satisfaction with delivered health care and (iv) cost-effectiveness of the intervention at 1-year follow-up. Trial registration: Netherlands trial register, NTR1946. Results: of the 11,476 registered eligible older persons, 7,285 (63%) participated in the screening. One thousand nine hundred and twenty-one (26%) had problems on ≥3 health domains. For 225 randomly chosen persons, a care plan was made. No beneficial effects were found on QoL, patients' functioning or healthcare use/costs. GPs experienced better overview of the care and stability, e.g. less unexpected demands, in the care. Conclusions: GPs prefer proactive integrated care. ‘Horizontal’ care using care plans for older people with complex problems can be a valuable tool in general practice. However, no direct beneficial effect was found for older persons. PMID:26764392

  11. Renegotiating cultural practices as a result of HIV in the eastern region of Malawi.

    2015-01-01

    A number of studies have shown that HIV awareness is very high among Malawians and yet infection rates are rising. Local cultural practices have been identified as contributing to this contradictory situation. Using data from 12 focus-group discussions collected in Balaka, Zomba, Machinga and Mangochi, the paper explores the reformulation of nine cultural practices as a preventive measure against HIV. The study reveals that cultural practices that involve sexual acts for completion are mediated through condoms and HIV tests. The study also shows that traditional herbs known for healing ailments are repurposed to symbolise sexual acts. We conclude that the idea of repurposing offers an avenue in which initiation and cleansing rites that involve sexual acts are replaced by other semiotics such as a traditional medicine called mtela. We also conclude that the modifications to cultural practices do not indicate complete abandonment of associated traditions, rather, they constitute the renegotiation of cultural practices and meanings associated with particular rites of passage. Lastly, we propose that a comprehensive prevention programme needs to be part of a wider national HIV-prevention effort combining a women and child rights and empowerment agenda and, critically, lifestyle lessons in a process of cultural renegotiation.

    Despite extensive knowledge of how to prevent or ameliorate serious diseases, natural disasters, environmental degradation, and a wide range of other problems, we often fail to take action that that would prevent or mitigate these problematic outcomes. In short, although we may have sound scientific knowledge about threats to future wellbeing, we appear to have limited insight into how to benefit from this knowledge. With this paper, we argue that our current scientific understanding of how to act in light of the future is limited, but we offer a theoretical analysis of future-oriented behavior at both individual and organizational levels. Specifically, the paper draws on a functional contextualist account of human language and cognition, Relational Frame Theory (RFT), and its integrated therapeutic approach, Acceptance and Commitment Therapy (ACT), and extends this framework to analyzing the evolution of the practices of groups and organizations. This framework can provide an understanding of how human behavior may be modified in the present to serve improving human wellbeing in the future at individual, organizational, and even national levels.

    Informal benchmarking using personal or professional networks has taken place for many years at the Kennedy Space Center (KSC). The National Aeronautics and Space Administration (NASA) recognized early on, the need to formalize the benchmarking process for better utilization of resources and improved benchmarking performance. The need to compete in a faster, better, cheaper environment has been the catalyst for formalizing these efforts. A pioneering benchmarking consortium was chartered at KSC in January 1994. The consortium known as the Kennedy Benchmarking Clearinghouse (KBC), is a collaborative effort of NASA and all major KSC contractors. The charter of this consortium is to facilitate effective benchmarking, and leverage the resulting quality improvements across KSC. The KBC acts as a resource with experienced facilitators and a proven process. One of the initial actions of the KBC was to develop a holistic methodology for Center-wide benchmarking. This approach to Benchmarking integrates the best features of proven benchmarking models (i.e., Camp, Spendolini, Watson, and Balm). This cost-effective alternative to conventional Benchmarking approaches has provided a foundation for consistent benchmarking at KSC through the development of common terminology, tools, and techniques. Through these efforts a foundation and infrastructure has been built which allows short duration benchmarking studies yielding results gleaned from world class partners that can be readily implemented. The KBC has been recognized with the Silver Medal Award (in the applied research category) from the International Benchmarking Clearinghouse.

    Objectives. We examined disparities in risk determinants and risk behaviors for sexually transmitted infections (STIs) between gay-identified, bisexual-identified, and heterosexual-identified young men who have sex with men (YMSM) and heterosexual-identified young men who have sex with women (YMSW) using a school-based sample of US sexually active adolescent males. Methods. We analyzed a pooled data set of Youth Risk Behavior Surveys from 2005 and 2007 that included information on sexual orientation identity, sexual behaviors, and multiple STI risk factors. Results. Bisexual-identified adolescents were more likely to report multiple STI risk behaviors (number of sex partners, concurrent sex partners, and age of sexual debut) compared with heterosexual YMSW as well as heterosexual YMSM and gay-identified respondents. Gay, bisexual, and heterosexual YMSM were significantly more likely to report forced sex compared with heterosexual YMSW. Conclusions. Our results provide evidence that sexual health disparities emerge early in the life course and vary by both sexual orientation identity and sexual behaviors. In particular, they show that bisexual-identified adolescent males exhibit a unique risk profile that warrants targeted sexual health interventions. PMID:24825214

    Although practice has long been known to improve perceptual performance, the neural basis of this improvement in humans remains unclear. Using fMRI in conjunction with a novel signal detection-based analysis, we show that extensive practice selectively enhances the neural representation of trained orientations in the human visual cortex. Twelve observers practiced discriminating small changes in the orientation of a laterally presented grating over 20 or more daily one-hour training sessions. Training on average led to a two-fold improvement in discrimination sensitivity, specific to the trained orientation and the trained location, with minimal improvement found for untrained orthogonal orientations or for orientations presented in the untrained hemifield. We measured the strength of orientation-selective responses in individual voxels in early visual areas (V1–V4) using signal detection measures, both pre- and post-training. Although the overall amplitude of the BOLD response was no greater after training, practice nonetheless specifically enhanced the neural representation of the trained orientation at the trained location. This training-specific enhancement of orientation-selective responses was observed in the primary visual cortex (V1) as well as higher extrastriate visual areas V2–V4, and moreover, reliably predicted individual differences in the behavioral effects of perceptual learning. These results demonstrate that extensive training can lead to targeted functional reorganization of the human visual cortex, refining the cortical representation of behaviorally relevant information.

    Background Although medical students’ initial orientation is an important point of transition in medical education, there is a paucity of literature on the subject and major variations in the ways that different institutions orient incoming medical students to their programs. Methods We conducted a discourse analysis of medical education orientation in the literature and on data from a survey of peer institutions’ approaches to orientation. Results These two discourses of orientation had clear similarities, in particular, the critical role of ceremony and symbols, and the focus on developing professionalism and physician identities. There were also differences between them, in particular, in the way that the discourse in the literature focused on the symbolic and professional aspects of orientation; something we have called ‘cultural orientation’. Meanwhile, those who were responsible for orientation in their own institutions tended to focus on the practical and social dimensions. Conclusion By examining how orientation has been described and discussed, we identify three domains of orientation: cultural, social, and practical. These domains are relatively distinct in terms of the activities associated with them, and in terms of who is involved in organizing and running these activities. We also describe orientation as a liminal activity system on the threshold of medical school where incoming students initially cross into the profession. Interestingly, this state of ambiguity also extends to the scholarship of orientation with only some of its aspects attracting formal enquiry, even though there is a growing interest in transitions in medical education as a whole. We hope, therefore, that this study can help to legitimize enquiry into orientation in all its forms and that it can begin to situate the role of orientation more firmly within the firmament of medical education practice and research.

    A questionnaire survey was performed to obtain pharmacy students' impressions of pharmacists' behavior, to classify these based on professionalism, and to analyze the relationship between these experiences and students' satisfaction with their clinical practice in Japan. The questionnaire was answered by 327 5th-year pharmacy school students upon completing clinical practice at community pharmacies from 2011 to 2012. They rated their satisfaction with their clinical practice using a 6-point Likert scale, and provided descriptions of their experience such as, "This health provider is professional", or "What a great person he/she is as a health provider". We counted the words and then categorized the responses into 10 traits, as defined by the American Pharmaceutical Association Academy of Students of Pharmacy-American Association of Colleges of Pharmacy, Council of Deans Task Force on Professionalism 1999, using text mining. We analyzed the relationship between their experiences with respectful persons, and satisfaction, using the Mann-Whitney U-test (significance level<0.05). Most students (337 of 364, 92.6%) reported experiences with respectful health providers. These students experienced significantly more satisfaction than did other students (p<0.001). We analyzed 343 sentences written by 261 students, using text mining analysis after excluding unsuitable responses. The word most used was "patient" (121 times). Many students noted their impression that the pharmacists had answered patients' questions. Of the 10 trait categories, "professional knowledge and skills" was mentioned most often (151 students).

    Numerous cases and outbreaks of Salmonella infection are attributable to shell eggs each year in the United States. Safe handling and consumption of shell eggs at home can help reduce foodborne illness attributable to shell eggs. A nationally representative Web survey of 1,504 U.S. adult grocery shoppers was conducted to describe consumer handling practices and consumption of shell eggs at home. Based on self-reported survey data, most respondents purchase shell eggs from a grocery store (89.5%), and these eggs were kept refrigerated (not at room temperature; 98.5%). As recommended, most consumers stored shell eggs in the refrigerator (99%) for no more than 3 to 5 weeks (97.6%). After cracking eggs, 48.1% of respondents washed their hands with soap and water. More than half of respondents who fry and/or poach eggs cooked them so that the whites and/or the yolks were still soft or runny, a potentially unsafe practice. Among respondents who owned a food thermometer (62.0%), only 5.2% used it to check the doneness of baked egg dishes when they prepared such a dish. Consumers generally followed two of the four core "Safe Food Families" food safety messages ("separate" and "chill") when handling shell eggs at home. To prevent Salmonella infection associated with shell eggs, consumers should improve their practices related to the messages "clean" (i.e., wash hands after cracking eggs) and "cook" (i.e., cook until yolks and whites are firm and use a food thermometer to check doneness of baked egg dishes) when preparing shell eggs at home. These findings will be used to inform the development of science-based consumer education materials that can help reduce foodborne illness from Salmonella infection. PMID:26197282

    More than two-thirds of patients in Germany use complementary and alternative medicine (CAM) provided either by physicians or non-medical practitioners (“Heilpraktiker”). There is little information about the number of family physicians (FPs) providing CAM. Given the widespread public interest in the use of CAM, this study aimed to ascertain the use of and attitude toward CAM among FPs in Germany. A postal questionnaire developed based on qualitatively derived data was sent to 3000 randomly selected FPs in Germany. A reminder letter including a postcard (containing a single question about CAM use in practice and reasons for non-particpation in the survey) was sent to all FPs who had not returned the questionnaire. Of the 3000 FPs, 1027 (34%) returned the questionnaire and 444 (15%) returned the postcard. Altogether, 886 of the 1471 responding FPs (60%) reported using CAM in their practice. A positive attitude toward CAM was indicated by 503 FPs (55%), a rather negative attitude by 127 FPs (14%). Chirotherapy, relaxation and neural therapy were rated as most beneficial CAM therapies by FPs, whereas neural therapy, phytotherapy and acupuncture were the most commonly used therapies in German family practices. This survey clearly demonstrates that CAM is highly valued by many FPs and is already making a substantial contribution to first-contact primary care in Germany. Therefore, education and research about CAM should be increased. Furthermore, with the provision of CAM by FPs, the role of non-medical CAM practitioners within the German healthcare system is to be questioned. PMID:19293252

    Objective To study the impact that physician, practice, and patient characteristics have on physician stress, satisfaction, mental, and physical health. Data Sources Based on a survey of over 5,000 physicians nationwide. Four waves of surveys resulted in 2,325 complete responses. Elimination of ineligibles yielded a 52 percent response rate; 1,411 responses from primary care physicians were used. Study Design A conceptual model was tested by structural equation modeling. Physician job satisfaction and stress mediated the relationship between physician, practice, and patient characteristics as independent variables and physician physical and mental health as dependent variables. Principle Findings The conceptual model was generally supported. Practice and, to a lesser extent, physician characteristics influenced job satisfaction, whereas only practice characteristics influenced job stress. Patient characteristics exerted little influence. Job stress powerfully influenced job satisfaction and physical and mental health among physicians. Conclusions These findings support the notion that workplace conditions are a major determinant of physician well-being. Poor practice conditions can result in poor outcomes, which can erode quality of care and prove costly to the physician and health care organization. Fortunately, these conditions are manageable. Organizational settings that are both “physician friendly” and “family friendly” seem to result in greater well-being. These findings are particularly important as physicians are more tightly integrated into the health care system that may be less clearly under their exclusive control.

    Blood components have been in use in clinical practice for many decades now. In spite of fairly clear guidelines regarding their use, inappropriate prescriptions for components are still rampant. We undertook this work to assess the appropriateness of fresh frozen plasma (FFP) transfusions in our hospital. A prospective audit of 504 transfusion orders for 1761 FFP units was conducted over a 6-month period which was followed by a re-audit of 294 FFP prescriptions for 961 units. In the initial audit, we identified 304 (60.3%) prescriptions which were inappropriate according to the British Committee for Standardization in Hematology (BCSH) guidelines. The re-audit performed after an educational campaign among clinicians showed a reduction in inappropriate requests by 26.6%. The specific areas of misuse were FFP transfusions in patients with hypoproteinaemic states (40.5%), anaemia (36.5%), bleeding without coagulation factor deficiency (10.2%) and volume depletion (9.2%). A significant 50.3% of requests in the initial audit and 38.4% in the re-audit were for single- or two-unit transfusions, which were subtherapeutic. FFP transfusions carry the same risks to the patients as any other blood component. Prescribers of these transfusions need to be aware of the clinical setting where their use is appropriate. Local hospital transfusion committees can play a vital role in overseeing transfusion practices to ensure optimal use of blood/component therapy. PMID:15180815

    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. PMID:24761922

  11. New circuit theory of multiconductor transmission lines resulting from a new practice of noise reduction

    TOKI, Hiroshi; SATO, Kenji

    2014-01-01

    In modern life, we are surrounded by and filled with electromagnetic noise caused by the dominant use of energy in the form of electricity. This situation is brought about by the fact that the noise is not understood theoretically. A new practice of noise reduction was introduced for the construction of Heavy Ion Medical Accelerator in Chiba (HIMAC). The key concept is a symmetric three-line circuit that arranges power supplies, noise filters and magnets around a third central ground line. A continuous theoretical effort forced us to find a new circuit theory involving a multiconductor transmission-line system starting from Maxwell’s equations without any approximation. We discuss the essence of all of these experimental and theoretical developments with the hope to remove unnecessary electromagnetic noise not only from power supplies, but also from all electric devices. The newly derived circuit theory of multiconductor transmission lines is universal, and establishes the validity of the practice of noise reduction. PMID:24522153

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

    2009-01-01

    Nursing has experienced an important methodological development, in which it gives priority to the individual, although at a socioeconomic level a marked interest is seen in the health care of the family unit and the NANDA (North American Nursing Diagnosis Association), NIC (Nursing Interventions Classification) and NOC (Nursing Outcomes Classification) nursing guidelines, using diagnoses, criteria of results and interventions orientated towards this aim. We consider to the family as an opened system consisted of human elements, with a common history, which they form a functional unit been ruled by own procedure. In this paper we look at those aspects that must be taken into account in nursing assessment of families from a systemic perspective, including some tools for data collection and analysis of information. In addition, we identify specific areas of intervention. We believe that the family must be studied from a nursing care point of view with its own characteristics as opposed to those possessed individually by each of its members. We also believe that, when assessment is centred on the Henderson unaided activities study or the Gordon functional health patterns, they are not useful in assessing the family unit. This work offers an assessment method centred on the family unit, which helps to identify the nursing diagnoses applicable to it. Our proposal, which has been successfully used by nursing students over the last few years, hopes to contribute to quality clinical practice with a tool orientated towards the family. PMID:19726212

  17. Catastrophic regime shifts in coral communities exposed to physical disturbances: simulation results from object-oriented 3-dimensional coral reef model.

    2009-07-21

    A 3-dimensional individual-based model, the ReefModel, was developed to simulate the dynamical structure of coral reef community using object-oriented techniques. Interactions among functional groups of reef organisms were simulated in the model. The behaviours of these organisms were described with simple mechanistic rules that were derived from their general behaviours (e.g. growing habits, competitive mechanisms, response to physical disturbance) observed in natural coral reef communities. The model was implemented to explore the effects of physical disturbance on the dynamical structure of a 3-coral community that was characterized with three functional coral groups: tabular coral, foliaceous coral and massive coral. Simulation results suggest that (i) the integration of physical disturbance and differential responses (disturbance sensitivity and growing habit) of corals plays an important role in structuring coral communities; (ii) diversity of coral communities can be maximal under intermediate level of acute physical disturbance; (iii) multimodality exists in the final states and dynamic regimes of individual coral group as well as coral community structure, which results from the influence of small random spatial events occurring during the interactions among the corals in the community, under acute and repeated physical disturbances. These results suggest that alternative stable states and catastrophic regime shifts may exist in a coral community under unstable physical environment. PMID:19306887

    Objectives To determine the effect of using the NHS Choices website on primary care consultations in England and Wales. We examined the hypothesis that using NHS Choices may reduce the frequency of primary care consultations among young, healthy users. Design Two cross-sectional surveys of NHS Choices users. Setting Survey of NHS Choices users using an online pop-up questionnaire on the NHS Choices website and a snapshot survey of patients in six general practices in London. Participants NHS Choices website users and general practice patients. Main outcome measures For both surveys, we measured the proportion of people using NHS Choices when considering whether to consult their GP practice and on subsequent frequency of primary care consultations. Results Around 59% (n = 1559) of online and 8% (n = 125) of general practice survey respondents reported using NHS Choices in relation to their use of primary care services. Among these, 33% (n = 515) of online and 18% (n = 23) of general practice respondents reported reduced primary care consultations as a result of using NHS Choices. We estimated the equivalent capacity savings in primary care from reduced consultations as a result of using NHS Choices to be approximately £94 million per year. Conclusions NHS Choices has been shown to alter healthcare-seeking behaviour, attitudes and knowledge among its users. Using NHS Choices results in reduced demand for primary care consultations among young, healthy users for whom reduced health service use is likely to be appropriate. Reducing potentially avoidable consultations can result in considerable capacity savings in UK primary care. PMID:21847438

    This study investigated inter-relationships among nutrition knowledge, habits, and attitudes of psychiatric healthcare providers. Data of nutritional intake was compared with that of the general population of the state of South Carolina, obtained from a previous public health study. Nutritional habits were determined from both a 24-hour recall and a separate three-day recall of dietary intake. Nutrition knowledge and attitudes were determined by validated questionnaires. The knowledge questionnaire consisted of 50 multiple-choice questions. Attitudes were determined using a semantic differential instrument consisting of phrases of descriptive bipolar adjectives. Dietary intake was analyzed using the Food Processor software and compared with the RDAs and with the intake of the general population. Nutrition knowledge was measured by the number of correct responses. Nutrition attitudes were assigned numerical scores and measured by a Likert scale. Only 3 of the subjects met 70% of indicator nutrients (iron, calcium, vitamin B6, and vitamin C). No significant relationships were established among attitudes, habits, and knowledge. Sixty-three percent of subjects perceived themselves as role models to patients, yet 90% of them practiced poor nutrition habits as compared with 97% of the general population. The higher the education level, the more likely that subjects felt nutrition is important for health. A comprehensive nutrition education program is essential for health care providers to promote successful nutrition education for the patients they serve. PMID:10112799

    This survey was conducted to provide an insight into the current clinical practice regarding the use of cardioversion for atrial fibrillation (AF) in Europe. Responses were received from 57 centres across Europe, 71.9% of which were university hospitals. For electrical cardioversion, general anaesthesia was managed by an anaesthesiologist in 73.9% of centres and by a cardiologist in 37%. In the majority of centres, electrical cardioversion was performed using a biphasic defibrillator (85.1%). Antiarrhythmic drugs were routinely prescribed prior to electrical cardioversion by 54.3% of hospitals. For pharmacological cardioversion in patients with no or minimal heart disease, the majority of centres (63.1%) chose intravenous flecainide or propafenone, whereas vernakalant was used by 35% of centres in patients with no or minimal-to-moderate structural heart disease. Most centres (71.7%) used a mandatory strategy of 3 weeks of oral anticoagulation prior to elective cardioversion in patients AF > 48 h, but 28.3% performed immediate cardioversion after a transoesophageal echocardiogram. Many centres are now performing electrical cardioversion on treatment with novel oral anticoagulants (up to 23.6% of cardioversions). PMID:23709570

    The International Education Training Centre (IETC) at Moscow State Unitary Enterprise Scientific and Industrial Association 'Radon' (SIA 'Radon'), in co-operation with the International Atomic Energy Agency (IAEA), has developed expertise and provided training to waste management personnel for the last 15 years. Since 1997, the educational system of the enterprise with the support of the IAEA has acquired an international character: more than 470 experts from 35 countries- IAEA Member States completed the professional development. Training is conducted at various thematic courses or fellowships for individual programs and seminars on IAEA technical projects. In June 2008 a direct agreement (Practical Arrangements) was signed between SIA 'Radon' and the IAEA on cooperation in the field of development of new technologies, expert's advice to IAEA Member States, and, in particular, the training of personnel in the field of radioactive waste management (RWM), which opens up new perspectives for fruitful cooperation of industry professionals. The paper summarizes the current experience of the SIA 'Radon' in the organization and implementation of the IAEA sponsored training and others events and outlines some of strategic educational elements, which IETC will continue to pursue in the coming years.

    radiation. The major results of the systematic work on optical orientation, both experimental and theoretical, at the Ioffe Institute and the Ecole Normale Supérieure in Paris are documented in the book Optical Orientation, edited by F Meier and B P Zakharchenya in the series Modern Problems in Condensed Matter Sciences [4], in which the foundations of optical orientation are comprehensively presented by renowned authors. This book is still the unsurpassed standard work in the field. If one asks what has become new since that publication in 1984 it is obviously the arrival of low-dimensional structures, two-dimensional heterostructures and zero-dimensional quantum dots. It has turned out that the quantum confinement can significantly modify the spin lifetime and the spin relaxation. The experimental work on spin alignment was done by a relative small number of researchers. However, the situation has substantially changed during the last decade. Research on spin-related phenomena has become very popular and the word 'spintronics' was coined. Spin research is no longer considered to be somewhat esoteric, since the replacement of silicon microelectronics based on the electron charge by spin-based electronics is being discussed. Whether these proposals can be realized remains to be seen. But one consequence has been a worldwide increase of high level basic research in spin phenomena. Another line of current research which has contributed to the popularity of spin-related research is quantum computing, based on spin-qubits. To be useful, solid state systems require long spin relaxation times and weak interaction with the environment. This is indispensable for low error rates. The difficulties in achieving these goals have been extensively discussed in the literature. Nowadays, because of the volume and diversity of spin-related work worldwide, a book on optical orientation like that edited by Meyer and Zakharchenya does not seem possible, so in this special issue of

    Objectives Previously, we identified a 10-year cohort of protocols from applications to the Norwegian Medicines Agency 1998–2007, consisting of 196 drug trials in general practice. The aim of this study was to examine whether trial results were published and whether trial funding and conflicts of interest were reported. Design Cohort study of trials with systematic searches for published results. Setting Clinical drug trials in Norwegian general practice. Methods We performed systematic literature searches of MEDLINE, Embase and CENTRAL to identify publications originating from each trial using characteristics such as test drug, comparator and patient groups as search terms. When no publication was identified, we contacted trial sponsors for information regarding trial completion and reference to any publications. Main outcome measures We determined the frequency of publication of trial results and trial characteristics associated with publication of results. Results Of the 196 trials, 5 were never started. Of the remaining 191 trials, 71% had results published in a journal, 11% had results publicly available elsewhere and 18% of trials had no results available. Publication was more common among trials with an active comparator drug (χ2 test, p=0.040), with a larger number of patients (total sample size≥median, p=0.010) and with a longer trial period (duration≥median, p=0.025). Trial funding was reported in 85% of publications and increased over time, as did reporting of conflicts of interest among authors. Among the 134 main journal articles from the trials, 60% presented statistically significant results for the investigational drug, and the conclusion of the article was favourable towards the test drug in 78% of papers. Conclusions We did not identify any journal publication of results for 29% of the general practice drug trials. Trials with an active comparator, larger and longer trials were more likely to be published. PMID:27067893

    Quality assurance programs have been part of the nuclear utility management process since the publication of the draft of 10CFR50 Appendix B in the late 1960s. The unwritten operational philosophy of nuclear quality assurance organizations focused on compliance with federal regulations. Adverse experiences, including operational events and extended shutdowns, prompted the gradual adoption of isolated practices extending beyond compliance orientation. These practices have an orientation that accommodates a definition of quality, a perspective of the role of nuclear quality assurance organizations in the overall concept of defense-in-depth, a definition of the segments of the nuclear quality assurance mission, and recent advances in the understanding of self-assessment. Observation of these practices at various nuclear utilities resulted in a syntheses of practices and approaches into a coherent quality-oriented nuclear quality assurance operating philosophy that is not totally adopted at any one utility.

    This study examined the relationship between therapist characteristics, therapeutic orientations, person-level and agency-level practices with cultural competency among 221 Los Angeles County community mental health clinicians. Results from an online survey indicated that compared to White therapists, ethnic minority therapists were more personally involved in communities of color, more likely to use a cultural framework in clinical practice, and perceived their agencies to be more culturally sensitive. Ethnic minority therapists also reported greater multicultural (MC) awareness and better MC counseling relationships with their clients than White therapists. Personal involvement in communities of color accounted for ethnic differences in MC awareness and MC counseling relationships. Compared to therapists with a strictly non-behavioral (psychodynamic or humanistic) orientation, therapists with an eclectic (or integrative) therapy orientation reported having a higher level of community knowledge. Therapists with an eclectic orientation reported greater MC awareness than therapists with a non-behavioral orientation, while both eclectic and behavioral (cognitive behavioral or behavior modification) therapists recounted better MC counseling relationships with their clients than therapists with a non-behavioral orientation. Community knowledge mediated eclectic vs. non-behavioral therapeutic orientation differences in MC awareness. Agency resources/linkages and outreach both moderated the relationship between therapeutic orientation and MC skills. Results suggest that if therapists become more personally involved with diverse populations, they will feel more culturally aware and feel like they have a better relationship with ethnic minority clients.

    Fecal testing can only reduce colorectal cancer mortality if patients with an abnormal test result receive a follow-up colonoscopy. As part of the Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC) project, we examined factors associated with adherence to follow-up colonoscopy among patients with abnormal fecal test results. As part of STOP CRC outreach, Virginia Garcia Memorial Health Center staff distributed 1753 fecal immunochemical tests (FIT), of which 677 (39 %) were completed, and 56 had an abnormal result (8 %). Project staff used logistic regression analyses to examine factors associated with colonoscopy referral and completion. Of the 56 patients with abnormal FIT results; 45 (80 %) had evidence of a referral for colonoscopy, 32 (57 %) had evidence of a completed colonoscopy within 18 months, and 14 (25 %) within 60 days of an abnormal fecal test result. In adjusted analysis, Hispanics had lower odds of completing follow-up colonoscopy within 60 days than non-Hispanic whites (adjusted OR 0.20; 95 % CI 0.04, 0.92). Colonoscopy within 60 days trended lower for women than for men (adjusted OR 0.25; 95 % CI 0.06-1.04). Among the 24 patients lacking medical record evidence of a colonoscopy, 19 (79 %) had a documented reason, including clinician did not pursue, patient refused, and colonoscopy not indicated. No reason was found for 21 %. Improvements are needed to increase rates of follow-up colonoscopy completion, especially among female and Hispanic patients. PMID:26874943

    Recently, a plenitude of novel laboratory tests has become available for physicians to improve the diagnostic and prognostic work up of patients. Yet, as with all tests, laboratory test can be falsely positive or falsely negative and potentially misguide clinicians and caregivers. Shortcomings of pre-analytical factors, test performance as well as an inappropriate ordering of laboratory tests contributes to diagnostic errors and potentially generate unnecessary costs. Laboratory tests should only be ordered, if results have clinical consequences and improve the assessment of the patient. Within this review focusing on the example of the inflammatory biomarker "Procalcitonin" for antibiotic stewardship and the hormonal marker testosterone, we aim to exemplify important draw backs and shortcomings in laboratory tests and the importance of interpretation of these results in the context of the clinical situation.

    BACKGROUND: General practice registrars are now required to undertake a summative assessment of their consulting skills. Simulated surgeries have been developed as an alternative to the existing method of assessing video-recorded consultations. AIM: To evaluate the simulated surgery assessment method, developed in the General Practice Postgraduate Education Department in Leicester, for use in assessing general practice consultation skills. METHOD: General practice registrars in Leicester performed two eight-patient simulated surgeries separated by four weeks. Assessment outcomes were compared to demonstrate the consistency of the method. Pilot surgeries in Yorkshire were videotaped, and then rated by video-raters trained for summative assessment. RESULTS: The method consistently identified those registrars who were competent and those who were not yet competent in consulting skills. It proved acceptable to candidate doctors and has fewer resource requirements for both examiners and candidates than other consulting skills assessment methods. CONCLUSION: The method developed in Leicester and successfully transferred to Yorkshire is feasible on a large scale, and offers an acceptable alternative to other consulting skills assessment methods. In this study it consistently identified competent from incompetent candidate doctors. PMID:9692278

    Control of asthma symptoms is, unfortunately, not a reality for many people with asthma. Asthma control is an ongoing challenge, requiring a multidisciplinary treatment approach. The National Asthma Education and Prevention Program (NAEPP) of the National Heart, Lung, and Blood Institute published its Guidelines for the Diagnosis and Management of Asthma in 1997, but the extent of implementation of recommendations in physician's practices remains to be determined. We sought to determine if a systematic implementation of the NAEPP practice guidelines would impact physician's treatment decisions for patients with asthma. The Asthma Care Network is a large, national, point-of-care program developed to assist health care providers in the assessment and management of their patients with asthma. Outcome measurements for the program included level of asthma control, activity limitation, sleep disruption, use of rescue medications, use of controller medications, and urgent care services. A total of 4,901 primary care physicians at 2,876 practice sites enrolled more than 60,000 patients. Nearly three fourths of patients reported symptoms consistent with a lack of asthma control (mean 74%, range 69-81%). Approximately 68% of pediatric patients and 78% of adult patients reported limited activities due to asthma in the past week. Sixty-two percent of pediatric patients and 68% of adult patients reported more than two symptomatic days in the past week. Approximately 40% of the patients surveyed were not using controller therapy. The overall percentage of patients reporting uncontrolled asthma who were prescribed a controller medication increased from 60% to 81%, and the use of inhaled corticosteroids containing medications among these patients increased by 52%. As a result of the assessment of the patients' level of asthma control during the office visit, physicians changed their patterns of prescribing controller therapy in patients with uncontrolled asthma.

    The 'Research Agenda for General Practice/Family Medicine and Primary Health Care in Europe' summarizes the evidence relating to the core competencies and characteristics of the Wonca Europe definition of GP/FM, and its implications for general practitioners/family doctors, researchers and policy makers. The European Journal of General Practice publishes a series of articles based on this document. The previous articles presented background, objectives, and methodology, as well results on 'primary care management' and 'community orientation' and the person-related core competencies of GP/FM. This article reflects on the general practitioner's 'specific problem solving skills'. These include decision making on diagnosis and therapy of specific diseases, accounting for the properties of primary care, but also research questions related to quality management and resource use, shared decision making, or professional education and development. Clinical research covers most specific diseases, but often lacks pragmatism and primary care relevance. Quality management is a stronghold of GP/FM research. Educational interventions can be effective when well designed for a specific setting and situation. However, their message that 'usual care' by general practitioners is insufficient may be problematic. GP and their patients need more research into diagnostic reasoning with a step-wise approach to increase predictive values in a setting characterized by uncertainty and low prevalence of specific diseases. Pragmatic comparative effectiveness studies of new and established drugs or non-pharmaceutical therapy are needed. Multi-morbidity and complexity should be addressed. Studies on therapy, communication strategies and educational interventions should consider impact on health and sustainability of effects. PMID:20825274

    We describe the methodology and results from our participation in the second Antibody Modeling Assessment experiment. During the experiment we predicted the structure of eleven unpublished antibody Fv fragments. Our prediction methods centered on template-based modeling; potential templates were selected from an antibody database based on their sequence similarity to the target in the framework regions. Depending on the quality of the templates, we constructed models of the antibody framework regions either using a single, chimeric or multiple template approach. The hypervariable loop regions in the initial models were rebuilt by grafting the corresponding regions from suitable templates onto the model. For the H3 loop region, we further refined models using ab initio methods. The final models were subjected to constrained energy minimization to resolve severe local structural problems. The analysis of the models submitted show that Accelrys tools allow for the construction of quite accurate models for the framework and the canonical CDR regions, with RMSDs to the X-ray structure on average below 1 Å for most of these regions. The results show that accurate prediction of the H3 hypervariable loops remains a challenge. Furthermore, model quality assessment of the submitted models show that the models are of quite high quality, with local geometry assessment scores similar to that of the target X-ray structures.

    Process management (PM) is a valuable method for the systematic analysis and structural optimisation of the quality and safety of clinical treatment. PM requires a high motivation and willingness to implement changes of both employees and management. Definition of quality indicators is required to systematically measure the quality of the specified processes. One way to represent comparable quality results is the use of quality indicators of the external quality assurance in accordance with Sect. 137 SGB V—a method which the Federal Joint Committee (GBA) and the institutions commissioned by the GBA have employed and consistently enhanced for more than ten years. Information on the quality of inpatient treatment is available for 30 defined subjects throughout Germany. The combination of specified processes with quality indicators is beneficial for the information of employees. A process-based indicator dashboard provides essential information about the treatment process. These can be used for process analysis. In a continuous consideration of these indicator results values can be determined and errors will be remedied quickly. If due consideration is given to these indicators, they can be used for benchmarking to identify potential process improvements. PMID:25523849

    Enhanced recovery after surgery (ERAS) protocols are now achieving worldwide diffusion in both university and district hospitals with special interest in colorectal surgery. The optimization of the patient’s preoperative clinical conditions, the careful intraoperative administration of fluids and drugs and the postoperative encouragement to resume the normal physiological functions as early as possible has produced results in a large amounts of studies. These approaches successfully challenged long-standing and well-established perioperative managements and finally achieved the status of gold standard treatments for the perioperative management of uncomplicated colorectal surgery. Even more important, it seems that the clinical improvement of the patient’s clinical management through ERAS protocols is now reaching his best outcomes (length of stay of 4-6 d after the operation) and therefore any further measures add little to the results already established (i.e., the adjunct of laparoscopic surgery to ERAS). Still dedicated meetings and courses around the world are exploring new aspects including the improvement the preoperative nutrition status to provide the energy necessary to face the surgical stress, the preoperative individuation of special requirements that could be properly addressed before the date of surgery and therefore would reduce the number of unnecessary days spent in hospital once fully recovered (i.e., rehabilitation, social discharges), and finally the development of an important web of out-of-hours direct access in order to individuate alarm symptoms in those patients at risk of complications that could prompt an early readmission.

    Despite the reported benefits of conservation agriculture (CA), its wider up-scaling in Sub-Saharan Africa (SSA) has remained fairly limited. This paper shows how a newly developed qualitative expert assessment approach for CA adoption (QAToCA) was applied to determine its adoption potential in SSA. CA adoption potential is not a predictor of observed adoption rates. Instead, our aim was to systematically check relevant factors that may be influencing its adoption. QAToCA delivers an assessment of how suitable conditions "and thus the likelihood for CA adoption" are. Results show that the high CA adoption potentials exhibited by the Malawi and Zambia case relate mostly to positive institutional factors. On the other hand, the low adoption potential of the Zimbabwe case, in spite of observed higher estimates, is attributed mainly to unstable and less secured market conditions for CA. In the case of Southern Burkina Faso, the potential for CA adoption is determined to be high, and this assessment deviates from lower observed figures. This is attributed mainly to strong competition of CA and livestock for residues in this region. Lastly, the high adoption potential found in Northern Burkina Faso is explained mainly by the fact that farmers here have no alternative other than to adopt the locally adapted CA system-Zaï farming. Results of this assessment should help promoters of CA in the given regions to reflect on their activities and to eventually adjust or redesign them based on a more explicit understanding of where problems and opportunities are found.

    This paper presents the practical parameter estimation for a slotless air-cored permanent magnet linear synchronous motor (PMLSM) using an analytical method and experiment. In the analytical method, the linkage flux is calculated through the generalized magnetic vector potential obtained by the space harmonics and transfer relation with each region of permanent magnet (PM) mover, air gap, and winding stator. This linkage flux is used to estimate the dynamic parameters such as magnetization inductance, backemf, and thrust constant. Also, the resistance and self-inductance with one phase are obtained by the experiment. Therefore, dynamic simulation of a linear synchronous motor composed of dynamic parameters is performed by the nonrotating (d-q) voltage equation. In good agreement with the estimated parameter values, the experimental results confirm the validity of the analysis method and simulation.

    This report documents the Phase 1 results of an effort aimed at formally verifying a key hardware component, called Scoreboard, of a Fault-Tolerant Parallel Processor (FTPP) being built at Charles Stark Draper Laboratory (CSDL). The Scoreboard is part of the FTPP virtual bus that guarantees reliable communication between processors in the presence of Byzantine faults in the system. The Scoreboard implements a piece of control logic that approves and validates a message before it can be transmitted. The goal of Phase 1 was to lay the foundation of the Scoreboard verification. A formal specification of the functional requirements and a high-level hardware design for the Scoreboard were developed. The hardware design was based on a preliminary Scoreboard design developed at CSDL. A main correctness theorem, from which the functional requirements can be established as corollaries, was proved for the Scoreboard design. The goal of Phase 2 is to verify the final detailed design of Scoreboard. This task is being conducted as part of a NASA-sponsored effort to explore integration of formal methods in the development cycle of current fault-tolerant architectures being built in the aerospace industry.

    Objectives: This study was designed to reach many segments of the diverse HIV/AIDS community and broaden understanding of how information can better assist people living with HIV/AIDS. Methods: Data were collected through a self-administered mail survey distributed nationwide at clinics, drug treatment centers, and other AIDS service organizations. Results: The 662 respondents preferred getting information from people—including health professionals, family, and friends—and considered people the most trustworthy, useful, understandable, and available information sources. Forty-three percent selected doctors as their most preferred source. The Internet was not rated highly overall but was preferred by those with more education or living in metropolitan areas. Seventy-two percent said they actively search for HIV/AIDS-related information, and 80% said they give advice or tell others where to get such information. However, 71% agreed that it is easy to feel overwhelmed by information, and 31% agreed that not seeking information can be beneficial. Conclusions: Overall, information seeking is an important activity for this sample of people living with HIV/AIDS. Many sources are widely available to them but, together, can be overwhelming. They rely on health professionals far more than print or media sources and receive encouragement and support from family and friends. PMID:16239938

    Although triathlon is growing in popularity at a remarkable rate, it has not been extensively studied. The aims of this research were to identify preparation strategies used by triathletes and to categorize these strategies according to gender and consultation with triathlon coaches. Survey data collected from 401 triathletes (207 males, 194 females) revealed training, nutritional, and mental preparation habits. Most participants engaged in strength training, consumed food and/or fluids during and after training, set training and competition goals, and applied mental preparation strategies during training and the hour before racing. Water was the most commonly consumed fluid; positive self-talk was the most used mental strategy. Participants were more likely to consult with a triathlon coach than a nutrition or sport psychology professional. Athletes with more years of experience in triathlon and those competing in longer distances were more likely to consult a triathlon coach. Female triathletes were more likely than male triathletes to train with others, use mental preparation strategies, and report feeling anxious before competitions. More male triathletes reported using nutritional supplements during training than their female counterparts. These findings add to the limited research base on triathletes' training habits, and hopefully will help guide practitioners who work with this group. The results provide guidance for collaborative efforts among training, nutrition, and mental health professionals to best support triathletes. PMID:21623532

    OBJECTIVE. During colonoscopy, advancing the endoscope can sometimes be difficult due to the appearance of loops or bends in the insertion tube. Therefore, research continues toward improving colonoscope technology. The aim of this study is to compare the use of colonoscopes equipped with "responsive insertion technology" (RIT) versus regular non-RIT colonoscopes. MATERIALS AND METHODS. Prospective, comparative and randomized trials that included patients submitted to colonoscopy. In group I, RIT colonoscopes were used, while in group II, colonoscopies with variable stiffness but without the other components of the RIT technology were used. Demographic variables and variables related to colonoscopy, as well as the pain perceived by the patient and the difficulty in performing endoscopy were recorded. RESULTS. A total of 122 patients were included in group I and 120 patients in group II. The cecal intubation rate was similar in both groups. The use of the RIT colonoscopes was associated with a lower cecal intubation time (4.4 ± 2.0 vs. 5.4 ± 3.5, p = 0.005) and a lower difficulty in performing examinations for both the endoscopist (19.1 ± 20.0 vs. 27.7 ± 22.2, p = 0.002) and the nursing staff (20.8 ± 17.0 vs. 26.3 ± 19.6, p = 0.04). No significant differences were found between both groups in the need for ancillary maneuvers or in the pain perceived by the patient. CONCLUSIONS. RIT colonoscopes allow cecal intubation in a shorter time compared to variable stiffness colonoscopes, and are associated with a greater level of ease of the procedure. PMID:24417584

    There is no place on earth more remote and inaccessible than Antarctica. In 2002, Raytheon Polar Services Co. (RPS) awarded The University of Texas Medical Branch (UTMB) at Galveston the contract to provide specialty medical services via telemedicine to the approximately 3,500 National Science Foundation (NSF) researchers and support personnel who rotate through Antarctica in a given year. We present the practices and results of the UTMB to the South Pole teledermatology program over the past six years, from 2003 to 2008. Issues encountered include logistics of sending out biopsies for pathologic diagnosis, limited bandwidth, and satellite availability for data transmission. The UTMB to the South Pole teledermatology program demonstrates the clinical practicality of telemedicine in providing dermatologic care to remote populations in extreme climate conditions.

    Oriental noodles have been consumed for thousands of years and remain an important part in the diet of many Asians. There is a wide variety of noodles in Asia with many local variations as result of differences in culture, climate, region and a host of other factors. In this article noodle classification, formulation, processing and evaluation are reviewed, with emphasis on eight major types. Wheat quality requirements, basic flour specifications, ingredient functions, and production variables are identified for different noodles. In the evaluation of flour for noodle making, three key quality attributes are considered: processability, noodle color and texture. Noodle process behavior is particularly important in the modern industrial production. Each noodle type has its own unique color and texture characteristics. Flour color, protein content, ash content, yellow pigment and polyphenol oxidase activity are important factors responsible for noodle color. Starch characteristics, protein content and quality play major roles in governing the texture of cooked noodles. However, the relative importance of starch and proteins varies considerably with noodle type. Starch pasting quality is the primary trait determining the eating quality of Japanese and Korean noodles that are characterized by soft and elastic texture, while protein quantity and strength are very important to Chinese-type noodles that require firm bite and chewy texture. Other factors such as ingredients added in the noodle formula and processing variables used during noodle preparation also affect the cooked noodle texture as well. PMID:11285682

    Background Despite the growing use of complementary and alternative medicine (CAM) by consumers in the U.S., little is known about the practice of CAM providers. The objective of this study was to describe and compare the practice patterns of naturopathic physicians in Washington State and Connecticut. Methods Telephone interviews were conducted with state-wide random samples of licensed naturopathic physicians and data were collected on consecutive patient visits in 1998 and 1999. The main outcome measures were: Sociodemographic, training and practice characteristics of naturopathic physicians; and demographics, reasons for visit, types of treatments, payment source and visit duration for patients. Result One hundred and seventy practitioners were interviewed and 99 recorded data on a total of 1817 patient visits. Naturopathic physicians in Washington and Connecticut had similar demographic and practice characteristics. Both the practitioners and their patients were primarily White and female. Almost 75% of all naturopathic visits were for chronic complaints, most frequently fatigue, headache, and back symptoms. Complete blood counts, serum chemistries, lipids panels and stool analyses were ordered for 4% to 10% of visits. All other diagnostic tests were ordered less frequently. The most commonly prescribed naturopathic therapeutics were: botanical medicines (51% of visits in Connecticut, 43% in Washington), vitamins (41% and 43%), minerals (35% and 39%), homeopathy (29% and 19%) and allergy treatments (11% and 13%). The mean visit length was about 40 minutes. Approximately half the visits were paid directly by the patient. Conclusion This study provides information that will help other health care providers, patients and policy makers better understand the nature of naturopathic care. PMID:15496231

    Tenants and part-owners are farming an increasing number of acres in the United States, while full-owners are farming fewer acres. This shift in ownership is a potential cause for concern because some previous research indicated that tenant and part-owner farmers were less likely to adopt conservation practices than farmers who owned the land they farmed. If that trend persists, ownership changes would signal a national drop in conservation adoption. Here we examine this issue using a survey of agricultural operators in the Clear Creek watershed in Iowa, a state with intensive agricultural production. We compare adoption of conservation practices, and preferences for conservation information sources and communication channels, between farmers who rent some portion of the land they farm (tenants and part-owners) and farmers who own all of the land they farm (full-owners). We find that renters are more likely to practice conservation tillage than full-owners, though they are less likely to rotate crops. In addition, renters report using federal government employees (specifically, Natural Resource Conservation Service and Farm Service Agency) as their primary sources of conservation information, while full-owners most frequently rely on neighbors, friends, and County Extension. These findings are significant for conservation policy because, unlike some past research, they indicate that renters are not resistant to all types of conservation practices, echoing recent studies finding an increase in conservation adoption among non-full-owners. Our results emphasize the importance of government conservation communication and can inform outreach efforts by helping tailor effective, targeted conservation strategies for owners and renters.

  17. Measuring the economic value of alternative clam fishing management practices in the Venice Lagoon: results from a conjoint valuation application

    This article focuses on the economic valuation of alternative clam management practices in the Venice Lagoon. The proposed valuation method is characterized by the design of a survey questionnaire applied to the fishermen population. In each questionnaire, two fishing alternatives are described. The respondent is asked to choose one of them. This valuation method, referred in the article as conjoint valuation, gives sufficient flexibility to set, alter, and combine the valuation of different clam management practices. Furthermore, this approach presents an important advantage to the well-known contingent valuation method since it makes the monetary valuation of each management attribute possible. Estimation results show that all three attributes used in the questionnaire to describe and value different clam management practices—price of the annual permit and fishing technological system—are statistically robust, indicating that fishermen bear a utility change whenever these attributes change. In particular, fishermen's willingness to pay for a larger clam fishing area ranges between 568 and 811 € per year. In addition, an individual's willingness to pay for a fishing practice exclusively based on the vibrant rake system ranges between 1005 and 2456 €. Finally, the adoption of a clam fish management practice in the Venice Lagoon that is exclusively based on the use of manual rakes, which is associated with the lowest damage to the lagoon ecosystem, will represent a welfare loss of 5904 € per fisherman per year. Combining such a value estimate with the total number of fishermen currently operating in the Lagoon of Venice, the welfare loss associated with the adoption of this type of clam management policy amounts to 11.8 € million per year. This figure can be regarded as an upper bound to the cost of implementation of a clam fishing system anchored in the use of manual, ecosystem friendly rakes.

    Competitive binding of the most common cations of the cytoplasm (K(+), Na(+), Ca(2+), and Mg(2+)) with DNA was studied by equilibrating oriented DNA fibers with ethanol/water solutions (65 and 52% v/v EtOH) containing different combinations and concentrations of the counterions. The affinity of DNA for the cations decreases in the order Ca > Mg >> Na approximately K. The degree of Ca(2+) and/or Mg(2+) binding to DNA displays maximum changes just at physiological concentrations of salts (60-200 mM) and does not depend significantly on the ethanol concentration or on the kind of univalent cation (Na(+) or K(+)). Ca(2+) is more tightly bound to DNA and is replaced by the monovalent cations to a lesser extent than is Mg(2+). Similarly, Ca(2+) is a better competitor for binding to DNA than Mg(2+): the ion exchange equilibrium constant for a 1:1 mixture of Ca(2+) and Mg(2+) ions, K(c)(Ca)(Mg), changes from K(c)(Ca)(Mg) approximately 2 in 65% EtOH (in 3-30 mM NaCl and/or KCl) to K(c)(Ca)(Mg) approximately 1.2-1.4 in 52% EtOH (in 300 mM NaCl and/or KCl). DNA does not exhibit selectivity for Na(+) or K(+) in ethanol/water solutions either in the absence or in the presence of Ca(2+) and/or Mg(2+). The ion exchange experimental data are compared with results of grand canonical Monte Carlo (GCMC) simulations of systems of parallel and hexagonally ordered, uniformly and discretely charged polyions with the density and spatial distribution of the charged groups modeling B DNA. A quantitative agreement with experimental data on divalent-monovalent competition has been obtained for discretely charged models of the DNA polyion (for the uniformly charged cylinder model, coincidence with experiment is qualitative). The GCMC method gives also a qualitative description of experimental results for DNA binding competitions of counterions of the same charge (Ca(2+) with Mg(2+) or K(+) with Na(+)). PMID:10545373

    In pursuit of such missions as Apollo, the National Aeronautics and Space Administration has called into being unique equipment that obviously has little direct application beyond the achievement of mission objectives. Yet, to assume that further direct application of space program hardware is somehow a measure of the industrial benefits accruing to the nation is to misunderstand how the creation of new technology affects modern industrial capability. This document presents a profile of the significant ways in which technological developments in response to aerospace mission requirements have been coupled into industrial practice, with the result being that improved products and processes are now being utilized to benefit the nation.

    An estimated 50% of medication errors go unreported, and error hiding is costly to hospitals and patients. This study explored one issue that may facilitate error hiding. Descriptive statistics were used to examine nursing students' achievement goal orientations in a high-fidelity simulation course. Results indicated that although this sample of nursing students held high mastery goal orientations, they also held moderate levels of performance-approach and performance-avoidance goal orientations. These goal orientations indicate that this sample is at high risk for error hiding, which places the benefits that are typically gleaned from a strong mastery orientation at risk. Understanding variables, such as goal orientation, that can be addressed in nursing education to reduce error hiding is an area of research that needs to be further explored. This article discusses the study results and evidence-based instructional practices for this sample's achievement goal orientation profile. PMID:24444007

    Despite more recent non-invasive modalities generating some credence in the literature, intracompartmental pressure testing is still considered the 'gold standard' for investigating chronic exertional compartment syndrome (CECS). Intracompartmental pressure testing, when used correctly, has been shown to be accurate and reliable. However, it is a user-dependent investigation, and the manner in which the investigation is conducted plays a large role in the outcome of the test. Despite this, a standard, reproducible protocol for intracompartmental pressure testing has not been described. This results in confusion regarding interpretation of results and reduces the tests' reliability. A summary of the current understanding of CECS is presented, along with the results of a survey of specialists in Australia and New Zealand who perform intracompartmental pressure testing, which confirms that a uniform approach is currently not used in clinical practice. This highlights the need for a consensus and standardised approach to intracompartmental pressure testing. PMID:21900703

    As more states adopt expanded newborn screening for metabolic disorders, the overall number of false positives increases. False-positive screening results have been associated with increased anxiety and stress in parents of infants who require follow-up testing, even after the infant's good health is confirmed. This article reviews the literature on the negative impact of false-positive newborn screening results on parents, along with a review of current communication practices for follow-up screening. The results of this review suggest that parental stress and anxiety can be reduced with improved education and communication to parents, specifically at the time of follow-up screening. Communication strategies with sample materials are proposed. PMID:16917730

    Worldwide, only a few "fatty" pig breeds exist with different and/or regional utilization. Using the Hungarian Mangalica, which almost went extinct in Europe and the Lao Moo Lat pig, which still has a large population in South-East Asia as exemples, we wanted to demonstrate that indigenous (fatty) pig breeds may represent both national value and tremendous economic potential. Since these less prolific and less productive breeds cannot contribute to mass production, new market roles and methods should be established for them in the premium segment of pork trading. Thus their preservation and propagation needs the comprehensive collaboration of commercial, governmental actors and researchers. Briefly summarizing the history, we report the current results of reproductive physiology research. The commercial renaissance of Mangalica pigs is indebted to the enthusiastic efforts of basic scientists, pig breeding experts and dedicated Mangalica producers. Scientific achievements were applied to practical breeding and production of delicious pork and processed products, which ultimately made the economic success in the Mangalica sector possible. Both, research on and utilization of endangered (pig) breeds maintain not only breed diversities, but also may improve the livelihood of farmers worldwide. PMID:24162808

    Abstract Objective The purpose of this study was to determine the feasibility of a chiropractic practice-based research network to investigate the treatment of acute neck pain (ANP) and to report resulting findings. Methods Participating chiropractors recruited sequentially presenting ANP patients on their initial visit to the office. Patients were treated by the chiropractors using their usual methods. Data were prospectively collected by having patients complete the Neck Disability Index, Characteristic Pain Intensity score, and a patient satisfaction questionnaire. Questionnaires were completed during routine office visits at baseline and then at weeks 1, 2, 4, 8, and 26, either in the office or by mail. Results Ten chiropractors supplied data on 99 patients. The number of cases contributed by each of the participating chiropractors ranged from 1 to 54, with a mean (SD) of 9.2 (10.5). Mean (SD) Neck Disability Index scores were 36 (17.9) at baseline and 9.8 (12.2) at the final evaluation; the Characteristic Pain Intensity scores were initially 55.3 (20.4) and were 24.5 (21.5) at the final evaluation. Transient minimal adverse effects were reported by chiropractors for only 7 (7.8%) patients. No serious adverse reactions were reported. Conclusion The practice-based research methodology used in this study appears to be a feasible way to investigate chiropractic care for ANP, and its methodologies could be used to plan future research.

    Background Antiretroviral treatment for HIV-infection before immunologic decline (early ART) and pre-exposure chemoprophylaxis (PrEP) can prevent HIV transmission, but routine adoption of these practices by clinicians has been limited. Methods Between September and December 2013, healthcare practitioners affiliated with a regional AIDS Education and Training Center in New England were invited to complete online surveys assessing knowledge, beliefs and practices regarding early ART and PrEP. Multivariable models were utilized to determine characteristics associated with prescribing intentions and practices. Results Surveys were completed by 184 practitioners. Respondent median age was 44 years, 58% were female, and 82% were white. Among ART-prescribing clinicians (61% of the entire sample), 64% were aware that HIV treatment guidelines from the Department of Health and Human Services recommended early ART, and 69% indicated they would prescribe ART to all HIV-infected patients irrespective of immunologic status. However, 77% of ART-prescribing clinicians would defer ART for patients not ready to initiate treatment. Three-fourths of all respondents were aware of guidance from the U.S. Centers for Disease Control and Prevention recommending PrEP provision, 19% had prescribed PrEP, and 58% of clinicians who had not prescribed PrEP anticipated future prescribing. Practitioners expressed theoretical concerns and perceived practical barriers to prescribing early ART and PrEP. Clinicians with higher percentages of HIV-infected patients (aOR 1.16 per 10% increase in proportion of patients with HIV-infection, 95% CI 1.01–1.34) and infectious diseases specialists (versus primary care physicians; aOR 3.32, 95% CI 0.98–11.2) were more likely to report intentions to prescribe early ART. Higher percentage of HIV-infected patients was also associated with having prescribed PrEP (aOR 1.19, 95% CI 1.06–1.34), whereas female gender (aOR 0.26, 95% CI 0.10–0.71) was associated

    Objectives: The International Diabetes Mellitus Practice Study (IDMPS) is a 5-year survey documenting changes in diabetes treatment practices in developing countries. The primary objective of this survey was to assess the therapeutic management of type 2 diabetes mellitus (T2DM) in real-life medical practice. The secondary objectives were to evaluate the clinical management of type 1 diabetes mellitus (T1DM) and to assess the proportion of all diabetic patients failing to reach the glycated haemoglobin (HbA1c) <7% target. Methods: Data were analysed for 738 patients (240 with T1DM and 498 with T2DM) included in wave 5 of the IDMPS in Morocco in 2011. Results: Nearly two-thirds (61%) of T2DM patients were treated with oral glucose-lowering drugs (OGLDs) alone, 13.1% were treated with insulin alone and 23.3% were treated with OGLDs plus insulin. Insulin use was less frequent, was initiated later and involved a greater use of premixes versus basal/prandial schedules compared to other populations evaluated in the IDMPS. The majority (92.5%) of T1DM patients were treated with insulin alone and the remainder received insulin plus an OGLD. Insulin protocols included basal + prandial dosing (37.5%) and premix preparations (41.3%). The recommended target of HbA1c <7% was achieved by only 22.2% of T1DM patients and 26.8% of T2DM patients. More macrovascular but fewer microvascular complications were reported in T2DM compared to T1DM patients. Late complications increased with disease duration so that 20 years after diagnosis, 75.7% of T2DM patients were found to have at least one late complication. Conclusions: The clinical burden of diabetes is high in Morocco and the majority of patients do not achieve the recommended glycaemia target, suggesting that there is a huge gap between evidence-based diabetic management and real-life practice. Better education of patients and improved compliance with international recommendations are necessary to deliver a better quality of

Methods: Athletic trainers (ATs) evaluated and tracked injuries at each practice and game during the 2014 youth football season. Players were drawn from 10 leagues across 4 states. The non–Heads Up Football (NHUF) group consisted of 704 players (none of whom were PW-affiliated) from 29 teams within 4 leagues. The HUF+PW group consisted of 741 players from 27 teams within 2 leagues. The HUF-only group consisted of 663 players from 44 teams within 4 leagues. Injury rates and injury rate ratios (IRRs) were reported with 95% CIs. Results: A total of 370 injuries were reported during 71,262 athlete-exposures (AEs) (rate, 5.19/1000 AEs). Compared with the NHUF group (7.32/1000 AEs), the practice injury rates were lower for the HUF+PW group (0.97/1000 AEs; IRR, 0.13; 95% CI, 0.08-0.21) and the HUF-only group (2.73/1000 AEs; IRR, 0.37; 95% CI, 0.26-0.53). Compared with the NHUF group (13.42/1000 AEs), the game injury rate was lower for the HUF+PW group (3.42/1000 AEs; IRR, 0.25; 95% CI, 0.15-0.44) but not for the HUF-only group (13.76/1000 AEs; IRR, 1.02; 95% CI, 0.73-1.43). Also, the HUF+PW game injury rate was lower than that of HUF-only (IRR, 0.20; 95% CI, 0.12-0.36). Higher injury rates were typically found in those aged 11 to 15 years compared with those aged 5 to 10 years. However, stronger effects related to HUF implementation and PW affiliation were seen among 11- to 15-year-olds. When restricted to concussions only, the sole difference was found

    Although it is well known that silent atrial fibrillation (AF) is associated with morbidity and mortality rates similar to those of symptomatic AF, no specific strategy for screening and management of this form of AF has been advocated. The purpose of this survey was to identify current practices for the diagnosis and management of silent AF. This survey is based on an electronic questionnaire sent to the European Heart Rhythm Association Research Network partners. Responses were received from 33 centres in 16 countries. The preferred screening methods for silent AF in patients with rhythm control by pharmacological therapy was 12-lead electrocardiogram (ECG) at outpatient visits (31.3%) and periodical 24 h Holter ECG recordings (34.4%), while after pulmonary vein isolation the corresponding figures were 6.3 and 65.6%, respectively. No consensus has been reached concerning the therapeutic approach for such patients. Most responders preferred rate control over rhythm control in patients with silent AF, although some favoured pulmonary vein isolation in young patients. However, oral anticoagulant therapy in patients at high thromboembolic risk was considered mandatory by most, provided that at least one episode of silent AF was documented, without recommending further investigations. The results of this survey have confirmed that there is currently no consensus regarding the screening and management of patients with silent AF and that clinical practice is not always consistent with the few existing evidence-based recommendations.

    The present study entailed conducting a content analysis of 1,434 ads/profiles posted on one of the most popular "Men who have Sex with Men" (MSM) websites that specifically fosters unprotected sex. Ads/profiles were selected randomly based on the American ZIP code of residence (n = 1,316), with a randomly-drawn oversampling of profiles of men who self-identified as heterosexual or "curious" rather than gay or bisexual (n = 118). Data were collected between September 2006 and September 2007. The purpose of the present paper is to examine the conjoint effects of self-identified sexual orientation and preference for having/not having sex while high, on men's sought-after sexual risk. Analytical comparisons of the four groups showed that, on most measures, the combination of sexual orientation and drug use preference during sex differentiated the men. Generally speaking, gay/bisexual men who advertised online for partners with whom they could have sex while high expressed the greatest interest in risky sexual behaviors (e.g., felching, unprotected oral sex, unprotected anal sex) and various risk-related preferences (e.g., multiple partner sex, anonymous sex, eroticizing ejaculatory fluids). This is especially true when they are compared to their heterosexual/"curious" counterparts whose online profiles were not as likely to indicate a desire for having sex while high. PMID:19543410

    Adverse childhood experiences (ACEs) have been linked to early sexual debut, which has been found to be associated with multiple adverse health outcomes. Sexual minorities and men tend to have earlier sexual debut compared to heterosexual populations and women, respectively. However, studies examining the association between ACEs and early sexual debut among men and sexual minorities are lacking. The aim of this study was to examine the sex and sexual orientation disparities in the association between ACEs and age at sexual debut. Data were obtained from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic and linear regression models were used to obtain crude and adjusted estimates and 95% confidence intervals adjusting for age, race/ethnicity, income, education, insurance and marital status for the association between ACEs (neglect, physical/psychological abuse, sexual abuse, parental violence, and parental incarceration and psychopathology) and early sexual debut. Analyses were stratified by sex and sexual orientation. Larger effect estimates depicting the association between ACEs and sexual debut were seen for women compared to men, and among sexual minorities, particularly among men who have sex with men (MSM) and women who have sex with women (WSW), compared to heterosexuals. Sexual health education programs with a focus on delaying sexual debut among children and adolescents should also consider addressing ACEs, such as neglect, physical, psychological and sexual abuse, witnessing parental violence, and parental incarceration and psychopathology. Public health practitioners, researchers and sexual health education curriculum coordinators should consider these differences by sex and sexual orientation when designing these programs.

    This study investigated associations between coming out to parents, experiences of parental support, and self-reported health behaviors and conditions among a population-based sample of LGB individuals using data collected via the 2002 Massachusetts Behavioral Risk Factor Surveillance System (BRFSS; N = 177). We explored the following two hypotheses: 1) Lesbian, gay, and bisexual (LGB) individuals who had never disclosed their sexual orientation to a parent would report higher levels of risk behaviors and poorer health conditions than those who had come out; and 2) among LGB respondents who had come out to their parents, the individuals whose parents had reacted unsupportively would report higher levels of risk behaviors and poorer health conditions than those who had come out to parents who were supportive. Approximately two thirds of gay and bisexual (GB) males and lesbian and bisexual (LB) females reported receiving adequate social and emotional support from the parent to whom they first disclosed their sexual orientation. Among LB females, no disclosure of sexual orientation to a parent was associated with significantly elevated levels of past-month illicit drug use (AOR 12.16, 95% CI 2.87-51.54), fair or poor self-reported health status (AOR 5.71, 95% CI 1.45-22.51), and >15 days of depression in the past month (AOR 5.95, 95% CI 1.78-19.90), controlling for potential confounders. However, nondisclosure to a parent by GB males was not associated with greater odds of any of the health indicators assessed. Among GB males, those with unsupportive parents were significantly more likely to report current binge drinking (AOR 6.94, 95% CI 1.70-28.35) and >15 days depression in the past month (AOR 6.08, 95% CI 1.15-32.15), and among LB females, those with unsupportive parents were significantly more likely to report lifetime illicit drug use (AOR 11.43, 95% CI 2.50-52.30), and >15 days depression in the past month (AOR 5.51, 95% CI 1.36-22.36).

    Background Malaria is the leading cause of illness and death in Papua New Guinea (PNG). Infection during pregnancy with falciparum or vivax malaria, as occurs in PNG, has health implications for mother and child, causing complications such as maternal anemia, low birth weight and miscarriage. This article explores knowledge, attitudes and practices concerning malaria during pregnancy and it’s prevention in Madang, PNG, a high prevalence area. Methods As part of a qualitative study in Madang, exploring MiP, participatory techniques (free-listing and sorting) were conducted along with focus group discussions, in-depth interviews (with pregnant women, health staff and other community members) and observations in the local community and health facilities. Results The main themes explored were attitudes towards and knowledge of MiP, its risks, and prevention. Although there was a general awareness of the term “malaria”, it was often conflated with general sickness or with pregnancy-related symptoms. Moreover, many preventive methods for MiP were related to practices of general healthy living. Indeed, varied messages from health staff about the risks of MiP were observed. In addition to ideas about the seriousness and risk of MiP, other factors influenced the uptake of interventions: availability and perceived comfort of sleeping under insecticide-treated mosquito nets were important determinants of usage, and women’s heavy workload influenced Chloroquine adherence. Conclusion The non-specific symptoms of MiP and its resultant conflation with symptoms of pregnancy that are perceived as normal have implications for MiP prevention and control. However, in Madang, PNG, this was compounded by the inadequacy of health staff’s message about MiP. PMID:25893405

    increasing time. The magnitudes of the anelastic strains were dependent on the measured directions, had a typical value of several hundred microstrains measured for about two weeks. To convert core orientation into geographic coordinate system, we conducted paleomagnetic measurements in shore based laboratory after the ASR measurements. Stepwise alternating field demagnetization on natural remanent magnetization revealed that three core samples from 177, 697 and 828 mbsf record paleomagnetic inclinations that are consistent with the latitude of the sample recovery site (C0019). Thus it is considered that declination can be used to convert core orientation for these three samples. In contrast, paleomagnetic inclination determined for core sample from 802 mbsf was not consistent with the latitude of the sample recovery site and conversion of the core orientation was not successful. Preliminarily, in-situ stress state after the Tohoku-oki earthquake determined by ASR at the four depths showed either in or close to the normal faulting stress regime. In addition, the maximum horizontal stress orientations by ASR were good consistent with those determined by borehole breakouts in Hole C0019B (Lin et al., 2013) at the two shallower depths where both breakout data and core orientation correction are available.

    Hypnosis is known to be effective in the treatment of pediatric pain. To better understand which strategies might be most useful, more knowledge is needed regarding the strategies that are actually used by experienced clinicians and the factors that influence their use. To address this knowledge gap, 35 health care professionals completed an online survey on the use of hypnosis in the management of pediatric chronic pain. The findings indicate that clinicians vary their use of hypnotic strategies primarily as a function of a patient's age but not as a function of theoretical orientation or amount of experience. The findings may be useful for guiding clinicians in their selection of strategies and suggestions when working with children with pain. PMID:27585730

    The changes in academic identity a teacher may undergo, as they modify their teaching practice, will vary depending on their experiences and the support they receive. In this paper, we describe the shifts in academic identity of two lecturers, a mathematician and a mathematics educator, as they both made changes to their teaching practice by implementing new questioning techniques in a large undergraduate mathematics course. Both the lecturers were members of the research group, which became their community of practice. Our findings recommend that lecturers endeavouring to step out and try changes to their teaching practice, particularly with large groups of students, belong to a community of practice. The community of practice provides a place for shared reflection, new learning, and opportunities to negotiate new identities.

    Purpose: To determine the patterns of radiotherapy practice for pancreatic cancer in Japan. Methods and Materials: A questionnaire-based national survey of radiotherapy for pancreatic cancer treated between 2000 and 2006 was conducted by the Japanese Radiation Oncology Study Group (JROSG). Detailed information on 870 patients from 34 radiation oncology institutions was accumulated. Results: The median age of all patients was 64 years (range, 36-88), and 80.2% of the patients had good performance status. More than 85% of patients had clinical Stage T3-T4 disease, and 68.9% of patients had unresectable disease at diagnosis. Concerning radiotherapy (RT), 49.8% of patients were treated with radical external beam RT (EBRT) (median dose, 50.4 Gy), 44.4% of patients were treated with intraoperative RT (median dose, 25 Gy) with or without EBRT (median dose, 45 Gy), and 5.9% of patients were treated with postoperative radiotherapy (median dose, 50 Gy). The treatment field consisted of the primary tumor (bed) only in 55.6% of the patients. Computed tomography-based treatment planning and conformal RT was used in 93.1% and 83.1% of the patients treated with EBRT, respectively. Chemotherapy was used for 691 patients (79.4%; before RT for 66 patients; during RT for 531; and after RT for 364). Gemcitabine was the most frequently used drug, followed by 5-fluorouracil. Conclusion: This study describes the general patterns of RT practice for pancreatic cancer in Japan. Most patients had advanced unresectable disease, and radical EBRT, as well as intraoperative RT with or without EBRT, was frequently used. Chemotherapy with gemcitabine was commonly used in conjunction with RT during the survey period.

    This study examined the influence of gender and Internet use on the sexual behavior orientation of young adults in Nigeria. Using an ex-post-facto design, data were collected from a total of 231 participants. Results of the hierarchical regression model provided support for the influence of gender and Internet use on sexual behavior orientation among young Nigerians. Further, results also revealed an interaction effect; as the use of the Internet increased, male participants reported a greater extent of risky sexual behavior orientation than their female counterparts. The findings were explained in the context of the theoretical foundations of the study, while practical implications for combating youths' risky sexual behavior orientation were highlighted.

    We present measurements of the magnetic field dependence of the penetration depth λ\\(H\\) for an untwinned YBa2Cu3O6.95 single crystal for temperatures from 1.2 to 7 K in dc fields up to 177 G and directions 0°, +/-45°, and 90° with respect to the crystal b axis. The edges of the platelet sample have been polished round to limit extrinsic effects. At 1.2 K, Δλ\\(H\\) in the a and b directions could be interpreted as agreeing with the Yip and Sauls prediction for the nonlinear Meissner effect in a d-wave superconductor. However, the systematics versus temperature and orientation, a key aspect of the theory, do not agree, and we conclude that the nonlinear Meissner effect is suppressed by a factor of 10 or larger.

    -time precipitation patterns for the Columbia Plateau. Four runoff events were recorded from October 2002 through September 2003; the stage recorder failed in the conventionally tilled drainage during two of the events. During the events in which the runoff was recorded, the conventionally tilled drainage yielded 19.39 m3 and 20.83 m3; for those same events the 10.0 ha direct seed drainage yielded 0 m3 and 7.24 m3. Total recorded runoff for the year from the conventionally tilled drainage was 40.21 m3, and 40.96 m3 from the 10.0 ha direct seeded drainage. Total annual erosion from the conventionally tilled drainage was 127.05 kg/ha and 8.18 kg/ha from the direct seeded drainage. No runoff or erosion were recorded from the direct seeded 25.0, 18.1 drainages, or the 1.6 ha hillslope. From October 2003 through September 2004, one runoff event was missed and eight events were recorded from the conventionally tilled drainage, yielding 149.89-m3 runoff, and 286.71-kg/ha soil loss. The direct seeded drainages and hillslope produced no runoff or erosion. Under the climatic conditions during these two winters, the direct seed practices used in this study effectively controlled, runoff and erosion compared to a conventionally farmed drainage, at scales both larger than and smaller than the conventionally drained area. These results demonstrate the immediate soil and water conservation effectiveness of the direct seed technology. They also portend changes in the downstream processes as channels adjust to reduced stormflow volume and energy, and a reduced sediment supply.

    Faced with growing knowledge management needs, enterprises are increasingly realizing the importance of seamlessly integrating critical business information distributed across both structured and unstructured data sources. Academicians have focused on this problem but there still remain a lot of obstacles for its widespread use in practice. One of the key problems is the absence of schema in unstructured text. In this paper we present a new paradigm for integrating information which overcomes this problem - that of Context Oriented Information Integration. The goal is to integrate unstructured data with the structured data present in the enterprise and use the extracted information to generate actionable insights for the enterprise. We present two techniques which enable context oriented information integration and show how they can be used for solving real world problems.

    Background The purpose of the study was to evaluate systematic reviews of research into two public health priorities, tobacco consumption and HIV infection, in terms of the reporting of data related to the applicability of trial results (i.e., whether the results of a trial can be reasonably applied or generalized to a definable group of patients in a particular setting in routine practice, also called external validity or generalisability). Methods All systematic reviews of interventions aimed at reducing or stopping tobacco use and treating or preventing HIV infection published in the Cochrane database of systematic reviews and in journals indexed in MEDLINE between January 1997 and December 2007 were selected. We used a standardized data abstraction form to extract data related to applicability in terms of the context of the trial, (country, centres, settings), participants (recruitment, inclusion and exclusion criteria, baseline characteristics of participants such as age, sex, ethnicity, coexisting diseases or co-morbidities, and socioeconomic status), treatment (duration, intensity/dose of treatment, timing and delivery format), and the outcomes assessment from selected reviews. Results A total of 98 systematic reviews were selected (57 Cochrane reviews and 41 non-Cochrane reviews); 49 evaluated interventions aimed at reducing or stopping tobacco use and 49 treating or preventing HIV infection. The setting of the individual studies was reported in 45 (46%) of the systematic reviews, the number of centres in 21 (21%), and the country where the trial took place in 62 (63%). Inclusion and exclusion criteria of the included studies were reported in 16 (16%) and 13 (13%) of the reviews, respectively. Baseline characteristics of participants in the included studies were described in 59 (60%) of the reviews. These characteristics concerned age in about half of the reviews, sex in 46 (47%), and ethnicity in 9 (9%). Applicability of results was discussed in 13 (13

    OBJECTIVES To describe the changes in process of care before and after an evidence-based fall reduction quality improvement collaborative in nursing facilities. DESIGN Natural experiment with nonparticipating facilities serving as controls. SETTING Community nursing homes. PARTICIPANTS Thirty-six participating and 353 non-participating nursing facilities in North Carolina. INTERVENTION Two in-person learning sessions, monthly teleconferences, and an e-mail discussion list over 9 months. The change package emphasized screening, labeling, and risk-factor reduction. MEASUREMENTS Compliance was measured using facility self-report and chart abstraction (n = 832) before and after the intervention. Fall rates as measured using the Minimum Data Set (MDS) were compared with those of nonparticipating facilities as an exploratory outcome. RESULTS Self-reported compliance with screening, labeling, and risk-factor reduction approached 100%. Chart abstraction revealed only modest improvements in screening (51% to 68%, P<.05), risk-factor reduction (4% to 7%, P = .30), and medication assessment (2% to 6%, P = .34). There was a significant increase in vitamin D prescriptions (40% to 48%, P = .03) and decrease in sedative-hypnotics (19% to 12%, P = .04) but no change in benzodiazepine, neuroleptic, or calcium use. No significant changes in proportions of fallers or fall rates were observed according to chart abstraction (28.6% to 37.5%, P = .17), MDS (18.2% to 15.4%, P = .56), or self-report (6.1–5.6 falls/1,000 bed days, P = .31). CONCLUSON Multiple-risk-factor reduction tasks are infrequently implemented, whereas screening tasks appear more easily modifiable in a real-world setting. Substantial differences between self-reported practice and medical record documentation require that additional data sources be used to assess the change-in-care processes resulting from quality improvement programs. Interventions to improve interdisciplinary collaboration need to be developed. PMID

    This study helps to quantify and describe orientation, evaluation, and integration practices pertaining to part-time clinical nursing faculty teaching in prelicensure nursing education programs. A researcher designed Web-based survey was used to collect information from a convenience sample of part-time clinical nursing faculty teaching in prelicensure nursing programs. Survey questions focused on the amount and type of orientation, evaluation, and integration practices. Descriptive statistics were used to analyze results. Respondents reported on average four hours of orientation, with close to half reporting no more than two hours. Evaluative feedback was received much more often from students than from full-time faculty. Most respondents reported receiving some degree of mentoring and that it was easy to get help from full-time faculty. Respondents reported being most informed about student evaluation procedures, grading, and the steps to take when students are not meeting course objectives, and less informed about changes to ongoing curriculum and policy.

    In an online survey, in which 18 experts participated, recommendations for research and practice to improve access to target groups were discussed. The recommendations were developed within the context of the KNP project. For the implementation of the recommendations, not only is an increased cooperation between science and practice particularly important, but also materials and training as well as standardization of methods. Furthermore, financial resources, especially for conducting evaluation studies are needed. PMID:26406533

  17. Students' coding orientation and school socializing context in their relation with students' scientific achievement

    The study described in this article is part of a broader research developed by the Project ESSA-Socio-logical Studies of the Classroom-whose main aim is to find out pedagogic practices more appropriate to all children. The study is mainly based on Bernstein's theory (1977, 1990; Domingos et al., 1986) and uses his concept of code as instrument of analysis. It intends to analyze the relation between general coding orientation and school achievement of socially differentiated children (social class, race, gender). It also intends to study the influence of differential modalities of school pedagogic practice on children's coding orientation. The results show that there is a mutual influence of family and school factors on students' coding orientation and science achievement. Specific characteristics of a pedagogic practice seem to be favourable to the development of the elaborated coding orientation required by the school.Received: 22 June 1993; Revised: 2 May 1994;

    A substrate is coated with a film to be recrystallized. A pattern of crystallization barriers is created in the film, for example, by etching voids in the film. An encapsulation layer is generally applied to protect the film, fill the voids and otherwise enhance a recrystallization process. Recrystallization is carried out such that certain orientations pass preferentially through the barrier, generally as a result of growth-velocity anisotropy. The result is a film of a specific predetermined crystallographic orientation, a range of orientations or a set of discrete orientations. 7 figs.

  20. Orienting hypnosis.

    Hope, Anna E; Sugarman, Laurence I

    2015-01-01

    This article presents a new frame for understanding hypnosis and its clinical applications. Despite great potential to transform health and care, hypnosis research and clinical integration is impaired in part by centuries of misrepresentation and ignorance about its demonstrated efficacy. The authors contend that advances in the field are primarily encumbered by the lack of distinct boundaries and definitions. Here, hypnosis, trance, and mind are all redefined and grounded in biological, neurological, and psychological phenomena. Solutions are proposed for boundary and language problems associated with hypnosis. The biological role of novelty stimulating an orienting response that, in turn, potentiates systemic plasticity forms the basis for trance. Hypnosis is merely the skill set that perpetuates and influences trance. This formulation meshes with many aspects of Milton Erickson's legacy and Ernest Rossi's recent theory of mind and health. Implications of this hypothesis for clinical skills, professional training, and research are discussed. PMID:25928677

    Dementia often has a serious impact on family life in household care giving situations. The qualitative study in applied gerontology presented here focuses on the subjective experiences of grandchildren and the intergenerational relationships of the family members. It includes 15 in-depth retrospective interviews with young adults (11 female, 4 male). The theoretical background is a sociological life-world-oriented approach by Alfred Schütz. The grandchildren reported a wide range of experiences with positive and enriching incidents prevailing, e.g., individual and familial competence in care giving, increased contact between family members, i.e., so-called"family cohesion", improvements in the grandchildren's social responsibility, and their acquired knowledge of the needs of older people and of persons with dementia. Individual stress was experienced because of so-called "challenging behavior" by the grandparents (e.g., aggressive behavior) or family circumstances when the demands were too great.A third category includes those experiences which seem to be "taken for granted" and are regarded as insignificant by the grandchildren. Because this category encompasses many of the grandchildren's own care giving activities, the widespread assumption that dementia must always cause younger carers stress is not true in general. The data suggest that living in a family that has difficulties in coping with the situation might be more demanding than dealing with the behavior and psychological symptoms of dementia. The grandchildren should be given access to age-appropriate information about the disease and the ways to communicate effectively with their grandparent needing care. PMID:21909775

    The therapeutic landscape for advanced melanoma has recently been transformed by several novel agents (immune checkpoint inhibitors and molecular-targeted agents). The prospective, multi-site, observational study IMAGE (ipilimumab: management of advanced melanoma in real practice) included a retrospective cohort to describe real-world treatment prior to approval of the immune checkpoint inhibitor ipilimumab. This retrospective cohort of patients, who started second-line/subsequent treatment (index therapy) for advanced melanoma within 3 years before ipilimumab approval, was selected randomly by chart review. Collected data included treatment history, patient outcomes, and healthcare resource utilization. All patients had ≥1 year of follow-up data. This analysis included 177 patients from Europe (69%) and North America (31%). The most common index therapies (used alone or in combination) were fotemustine (23%), dacarbazine (21%), temozolomide (14%), and platinum-based chemotherapy (14%). Most patients (89%) discontinued index treatment during the study period; the most common reason was disease progression (59%). Among patients with tumor assessment (153/177; 86%), 2% had complete response, 5% had partial response, and 12% had stable disease on last tumor assessment. At 1-year study follow-up, median progression-free survival was 2.6 months (95% confidence interval [CI], 2.1-2.9) and median overall survival was 8.8 months (95% CI, 6.5-9.7). During follow-up, 95% of the patients had healthcare visits for advanced melanoma, 74% of whom were hospitalized or admitted to a hospice facility. These results provide insights into patient care with advanced melanoma in the era before ipilimumab and may serve as a benchmark for new agents in future real-world studies. PMID:27118102

    Background Although numbers of physicians credentialed to prescribe buprenorphine has increased over time, many credentialed physicians may be reluctant to treat individuals with opioid use disorders due to discomfort with prescribing buprenorphine. Though prescribing physicians are required to complete a training course, many have questions about buprenorphine and treatment guidelines have not been updated to reflect clinical experience in recent years. We report on an expert panel process to update and expand buprenorphine guidelines. Methods We identified candidate guidelines through expert opinion and a review of the literature and used a modified RAND/UCLA Appropriateness Method to assess the validity of the candidate guidelines. An expert panel completed two rounds of rating, with a meeting to discuss the guidelines between the first and second rating. Results Through the rating process, expert panel members rated 90 candidate guideline statements across eight domains, including candidacy for buprenorphine treatment, dosing of buprenorphine, psychosocial counseling, and treatment of co-occurring depression and anxiety. A total of 65 guideline statements (72%) were rated as valid. Expert panel members had agreement in some areas, such as the treatment of co-occurring mental health problems, but disagreement in others, including the appropriate dosing of buprenorphine given patient complexities. Conclusions Through an expert panel process, we developed an updated and expanded set of buprenorphine treatment guidelines; this additional guidance may increase credentialed physicians’ comfort with prescribing buprenorphine to patients with opioid use disorders. Future efforts should focus on appropriate dosing guidance and ensuring that guidelines can be adapted to a variety of practice settings. PMID:25844527

    A review of evidence on the benefits and challenges of student orientation is used in this article alongside experiences of orientation days on a children's ward to consider ways in which such programmes could be improved. Orientation to clinical placements can enhance learning by helping students to feel they fit in, reduce anxiety and increase motivation to learn through early identification of learning outcomes. However, there are challenges in the practical implementation of orientation including timing of students' starting dates, staff time, consistency and level of information and teaching. Increased involvement of individual mentors could improve orientation and optimise students' learning experiences. PMID:17326556

    The results of a survey sent to practice leaders in the ACR Practice of Radiology Environment Database show that the majority of responding groups will continue to hire recently trained residents and fellows even though they have been unable to take the final ABR diagnostic radiology certifying examination. However, a significant minority of private practice groups will not hire these individuals. The majority of private practices expect the timing change for the ABR certifying examinations to affect their groups' function. In contrast, the majority of academic medical school practices expect little or no impact. Residents and fellows should not expect work time off or protected time to study for the certifying examination or for their maintenance of certification examinations in the future. PMID:25737379

    The primary aim of the STAR Study (Statins Target Assessment in Real practice) was to determine the LDL-cholesterol reduction and to analyse patient's and therapeutic factors associated to LDL-cholesterol target attainment in newly treated subjects with statins in an unselected population in clinical practice setting. Administrative databases (including pharmaceutical prescriptions and hospital admissions) and laboratory test databases (including LDL-cholesterol values) of five local health units, distributed in Emilia Romagna, Toscana and Umbria, were linked. A retrospective cohort study was conducted and all subjects aged > or =18 years with a first prescription for statins (newly treated subjects) between January 1st, 2007 and June 30th, 2008 were included. All statin prescriptions over a 12 months follow-up period were considered and used to calculate adherence to treatment. Baseline and follow-up LDL-cholesterol, respectively, were defined according to the nearest determination to the first prescription for statins and to the end of the follow-up period. A total of 3.232 subjects was included, 1.516 males (47%) and 1.716 females (53%), with an average age equal to 65.9 +/- 11.3 years. Among included subjects, 22.,6% had a gap to LDL-cholesterol target <10%, 30.0% between 10 and 29%, 20.7% between 30 and 49%, and 26.7% . or =50%. Among those with a gap to target > or =50%, 30-49%, and 10-29%, respectively, LDL-cholesterol target was attained by 7.1%, 41.8%, and 62.% of subjects. LDL-cholesterol target attainment was associated to gap to target, adherence with treatment, and type of statin. PMID:22567731

  7. Reactions of oriented molecules.

    1976-07-01

    Beams of oriented molecules have been used to directly study geometrical requirements in chemical reactions. These studies have shown that reactivity is much greater in some orientations than others and demonstrated the existence of steric effects. For some reactions portions of the orientation results are in good accord with traditional views of steric hindrance, but for others it is clear that our chemical intuition needs recalibrating. Indeed, the information gained from simultaneously orienting the reactants and observing the scattering angle of the products may lead to new insights about the detailed mechanism of certain reactions. Further work must be done to extend the scope and detail of the studies described here. More detailed information is needed on the CH(3)I reaction and the CF(3)I reaction. The effects of alkyl groups of various sizes and alkali metals of various sizes are of interest. In addition, reactions where a long-lived complex is formed should be studied to see if orientation is important. Finally, it would be of interest to apply the technique to the sort of reactions that led to our interest in the first place: the S(N)2 displacements in alkyl halides where the fascinating Walden inversion occurs.

    Through the rapid progress in neuropharmacology it seems to become possible to effectively improve our cognitive capacities and emotional states by easily applicable means. Moreover, deep-brain stimulation may allow an effective therapeutic option for those neurological and psychiatric diseases which still can not be sufficiently treated by pharmacological measures. So far, however, both the benefit and the harm of these techniques are only insufficiently understood by neuroscience and detailed ethical analyses are still missing. In this article ethical criteria and most recent empirical evidence are systematically brought together for the first time. This analysis shows that it is irrelevant for an ethical evaluation whether a drug or a brain-machine interface is categorized as "enhancement" or "treatment" or whether it changes "human nature". The only decisive criteria are whether the intervention (1.) benefits the patient, (2.) does not harm the patient and (3.) is desired by the patient. However, current empirical data in both fields, neuropharmacology and deep-brain stimulation are still too sparse to adequately evaluate these criteria. Moreover, the focus in both fields has been strongly misled by neglecting the distinction between "benefit" and "efficacy": In past years research and clinical practice have only focused on physiological effects, but not on the actual benefit to the patient.

    We conducted two telephone surveys of all United Kingdom adult intensive care units in 2007/8 and 2010 to assess practice with regard to intensive insulin therapy for glycaemic control in critically ill patients, and to assess the change in practice following publications in 2008 and 2009 that challenged the evidence for this therapy. Of 243 units that had a written policy for intensive insulin therapy in 2007/8, 232 (96%) still had a policy in 2010. One hundred and six (46%) units had updated their policy in response to new evidence, whereas 126 (54%) stated that it had remained the same. Where intensive care units had changed their policy, we found a significant increase in target limits and a wider target range. Regional variations in practice were also seen. Across seven regions, the percentage of units where the glycaemic control policy had been updated since 2007/8 varied from nil to 78.9%. PMID:21254983

    Socially-oriented Observations (SOO) in the Russian North have been carried out within multidisciplinary IPY PPS Arctic project under the leadership of Norway and supported by the Research Council of Norway as well as Russian Academy of Sciences. The main objective of SOO is to increase knowledge and observation of changes in quality of life conditions (state of natural environment including climate and biota, safe drinking water and foods, well-being, employment, social relations, access to health care and high quality education, etc.) and - to reveal trends in human capital and capacities (health, demography, education, creativity, spiritual-cultural characteristics and diversity, participation in decision making, etc.). SOO have been carried out in industrial cities as well as sparsely populated rural and nature protection areas in observation sites situated in different bioms (from coastal tundra to southern taiga zone) of Murmansk, Arkhangelsk Oblast and Republic of Komi. SOO were conducted according to the international protocol included in PPS Arctic Manual. SOO approaches based both on local people's perceptions and statistics help to identify main issues and targets for life quality, human capital and environment improvement and thus to distinguish leading SOO indicators for further monitoring. SOO have revealed close interaction between human resources, quality of life and environmental changes. Negative changes in human capital (depopulation, increasing unemployment, aging, declining physical and mental health, quality of education, loss of traditional knowledge, marginalization etc.), despite peoples' high creativity and optimism are becoming the major driving force effecting both the quality of life and the state of environment and overall sustainability. Human induced disturbances such as uncontrolled forests cuttings and poaching are increasing.

    This paper focuses on recent trends in risky sexual practices for HIV/AIDS among men who have sex with men (MSM) in Fortaleza, Ceará State, Brazil. Four cross-sectional surveys were conducted (1995, 1998, 2002, and 2005) among MSM 14 years or older who reported oral or anal sex in the previous 12 months. Sexual practices were considered risky whenever the respondent reported unprotected receptive or insertive anal intercourse in the six months preceding the interview. Different selection techniques were used to recruit the study population: snowball (1995, 1998, 2002 - 32%); time-space sampling (2002 - 68%); and respondent-driven sampling (2005). Analyses were based on the comparison between proportions. High rates of risky sexual practices were reported in 1995 (49.9%), decreasing in 1998 (32.6%), increasing again in 2002 (51.3%), and showing the lowest level in 2005 (31.4%). Participants with more schooling increased their risky practices from 1998 to 2002, decreasing in 2005. Among individuals with medium or low schooling, risky behavior declined from 2002 to 2005. The article highlights the need for behavioral surveillance to properly address STD/HIV prevention. PMID:19503969

    2016-07-01

    While the optimum-orientation concept is frequently used in studies on cluster decays involving deformed nuclei, the orientation-averaging concept is used in most alpha decay studies. We investigate the different decay stages in both the optimum-orientation and the orientation-averaging pictures of the cluster decay process. For decays of 232,233,234U and 236,238Pu isotopes, the quantum knocking frequency and penetration probability based on the Wentzel–Kramers–Brillouin approximation are used to find the decay width. The obtained decay width and the experimental half-life are employed to estimate the clusters preformation probability. We found that the orientation-averaged decay width is one or two orders of magnitude less than its value along the non-compact optimum orientation. Correspondingly, the extracted preformation probability based on the averaged decay width increases with the same orders of magnitude compared to its value obtained considering the optimum orientation. The cluster preformation probabilities estimated by the two considered schemes are in more or less comparable agreement with the Blendowske–Walliser (BW) formula based on the preformation probability of α ({S}α {{a}{{v}}{{e}}}) obtained from the orientation-averaging scheme. All the results, including the optimum-orientation ones, deviate substantially from the BW law based on {S}α {{o}{{p}}{{t}}} that was estimated from the optimum-orientation scheme. To account for the nuclear deformations, it is more relevant to calculate the decay width by averaging over the different possible orientations of the participating deformed nuclei, rather than considering the corresponding non-compact optimum orientation.

    Several kinds of electrocardiogram monitoring systems are now available in the clinical practice. The aim of this European Heart Rhythm Association (EHRA) survey was to assess the use of different monitoring techniques in the evaluation of patients with unexplained syncope, palpitations, and in those with established diagnosis of atrial fibrillation. Forty-five centres in Europe answered the questionnaire and the majority (78%) were university hospitals. The answers showed a discrepancy between the recommended use of implantable loop recorders (ILRs) in patients with unexplained syncope and the use of this device in clinical practice. In most of the cases only a minority of patients (<20%) seemed to actually receive an ILR as a part of the diagnostic process in accordance to the current guidelines. Holter monitoring systems and external loop recorders seemed to be the preferred monitoring techniques both in patients with recurrent palpitations and in those with established diagnosis of atrial fibrillation.

    Hand hygiene literature is scarce in the southern Mediterranean area. In order to establish a baseline position, a study was performed in four Mediterranean countries. Seventy-seven hospital wards in 22 hospitals were enrolled and information on hand hygiene practice and facilities were collected. The overall compliance rate was very low (27.6%), and was significantly higher where the perceived risk was considered to be high. Intensive care units showed the highest level of compliance. Analysis by country indicated higher compliance in Egypt (52.8%) and Tunisia (32.3%) compared with Algeria (18.6%) and Morocco (16.9%). Facilities for hand hygiene, particularly consumables, were shown to be deficient. Multi-approach programmes combining the production of official local recommendations, education and regular evaluation of hand hygiene practice are much needed to improve the present situation.

    Geriatric patients with non-valvular atrial fibrillation (AF) are increasingly being treated with novel oral anticoagulants (NOAC) to prevent ischemic stroke. This article highlights the outcome of an expert meeting on the practical use of NOAC in elderly patients. An interdisciplinary group of experts discussed the current situation of stroke prevention in geriatric patients and its practical management in daily clinical practice. The topic was examined through focused impulse presentations and critical analyses as the basis for the expert consensus. The key issues are summarized in this paper. The European Society of Cardiology (ESC) guidelines from 2012 for the management of patients with non-valvular AF recommend NOAC as the preferred treatment and vitamin K antagonists (VKA) only as an alternative option. Currently, the NOAC factor Xa inhibitors apixaban and rivaroxaban and the thrombin inhibitor dabigatran are more commonly used in clinical practice for patients with AF. Although these drugs have many similarities and are often grouped together it is important to recognize that the pharmacology and dose regimes differ between compounds. Especially n elderly patients NOAC drugs have some advantages compared to VKA, e.g. less drug-drug interactions with concomitant medication and a more favorable risk-benefit ratio mostly driven by the reduction of bleeding. Treatment of anticoagulation in geriatric patients requires weighing the serious risk of stroke against an equally high risk of major bleeding and pharmacoeconomic considerations. Geriatric patients in particular have the greatest benefit from NOAC, which can also be administered in cases of reduced renal function. Regular control of the indications is indispensable, as also for all other medications of the patient. The use of NOAC should certainly not be withheld from geriatric patients who have a clear need for oral anticoagulation. PMID:26861870

Because of their speed and parallel processing capabilities, optical correlators should prove valuable in this application. This paper considers two algorithms for object orientation estimation based on optical correlations and presents some initial simulation results.

    This study aimed to explore the prospective relationship between maternal feeding practices and young children's frequency of consumption of fruits, vegetables and sweets, and also child weight-for-height z-scores. Participants were 60 mothers who completed questionnaires when their children were 1 year old and again when their children were 2 years old. Regression analyses were performed. After controlling for availability and prior child consumption of the target food, maternal use of pressure to eat at 1 year predicted lower child frequency of fruit consumption at 2 years and approached significance for lower vegetable consumption. Maternal modelling of healthy eating at 1 year predicted higher child frequency of vegetable consumption at 2 years. Restriction did not significantly predict child frequency of consumption of fruits, vegetables or sweets over time. Child weight-for-height scores at 2 years were predicted by weight-for-height at 1 year but not by feeding practices. The findings suggest that maternal feeding practices can influence child eating at a very young age. Interventions should focus on encouraging parents to model healthy eating to promote healthy eating in children. PMID:21569809

    The aims of this research study were to investigate moral distress among emergency department (ED) nurse practitioners (NPs) and examine relationships between moral distress and level of practice independence as well as intent to leave a position. Moral distress has been studied regarding registered nurses and physicians (MDs) but less so in NPs. It is important to explore moral distress in NPs because they tread a unique path between nursing and physician roles. Moral distress may play a significant role in staff nurses' intention to leave practice, and level of practice independence is found to have a relationship with NPs' intention to leave. A convenience sample of ED NPs was obtained from a mailing list of a national nursing specialty organization, the Emergency Nurses Association. Using a correlational design, survey methods assessed moral distress with the Moral Distress Scale-Revised (MDS-R), level of practice independence with the Dempster Practice Behavior Scale, and intent to leave with self-report. Correlational and regression analyses of data were conducted to characterize moral distress among ED NPs and associations between moral distress, level of practice independence, and intent to leave. Results found ED NPs do experience moral distress with poor patient care results from inadequate staff communication and working with incompetent coworkers in their practice. The MDS-R was a significant predictor of intention to leave among respondents. This study is the first of its kind to explore moral distress in ED NPs. Results suggest moral distress influences ED NPs' intent to leave their position. Further studies are needed to explore the findings from this research and to formulate interventions to alleviate moral distress in ED NPs and improve retention in the clinical setting.

  9. Value orientation and forest management: the forest health debate.

    Among both forest practitioners and the general public, "forest health" has become an issue of contention. Whereas the debate over which treatments will best achieve healthy forests has been framed largely by the popular media and politicians as a struggle between industry and environmentalists, the views of the general public remain unexplored. Survey results from Oregon and Washington residents were used to assess the relationships between respondents' self-described environmental or economic priorities and the following two variables: (1) acceptability of forest management practices and (2) perceived threats to forest health. Findings indicate that active management was generally accepted by a majority of respondents regardless of their environmental or economic orientation. Disagreement emerged, however, when the appropriateness of specific management practices within specific forest conditions was examined. Additionally, strong evidence was found for a relationship between self-described environmental or economic orientation and perceived threats to forest health. Those with an environmentally oriented viewpoint tended to perceive human-caused factors as the largest threats, whereas those with an economic orientation saw naturally occurring processes as the greatest threats. These findings suggest that the issue of contention is not active management per se. Rather, the major divisions in the forest health debate are defined by specific contexts and circumstances, as well as the management practices used. PMID:16222459

    We study the impact of coil orientation on the motor threshold (MT) and present an optimal coil orientation for stimulation of the foot. The result can be compared to results of models that predict this orientation from electrodynamic properties of the media in the skull and from orientations of cells, respectively. We used a robotized TMS system for precise coil placement and recorded motor-evoked potentials with surface electrodes on the abductor hallucis muscle of the right foot in 8 healthy control subjects. First, we performed a hot-spot search in standard (lateral) orientation and then rotated the coil in steps of 10° or 20°. At each step we estimated the MT. For navigated stimulation and for correlation with the underlying anatomy a structural MRI scan was obtained. Optimal coil orientation was 33.1±18.3° anteriorly in relation to the standard lateral orientation. In this orientation the threshold was 54±18% in units of maximum stimulator output. There was a significant difference of 8.0±5.9% between the MTs at optimal and at standard orientation. The optimal coil orientations were significantly correlated with the direction perpendicular to the postcentral gyrus (). Robotized TMS facilitates sufficiently precise coil positioning and orientation to study even small variations of the MT with coil orientation. The deviations from standard orientation are more closely matched by models based on field propagation in media than by models based on orientations of pyramidal cells. PMID:23593200

    Chrysler, M.; Chirayath, V.; McDonald, A.; Lim, Z.; Shastry, K.; Gladen, R.; Fairchild, A.; Koymen, A.; Weiss, A.

    Positron annihilation induced Auger electron spectroscopy (PAES) was used to study the positron induced low energy electron spectra from HOPG and a sample composed of 6-8 layers of graphene grown on polycrystalline copper. A low energy (~2eV) beam of positrons was used to implant positrons into a surface localized state on the graphene and HOPG samples. Measurements of the energy spectra of the positron induced electrons obtained using a TOF spectrometer indicate the presence of an annihilation induced KLL C Auger peak (at ~263 eV) along with a narrow low energy secondary peak due to an Auger mediated positron sticking (AMPS) process. A broad spectral feature was also observed below ~15 eV which we believe may be due to a VVV C Auger transition not previously observed. The energy dependence of the integrated intensity of the AMPS peak was measured for a series of incident positron kinetic energies ranging from ~1.5 eV up to 11 eV from which the binding energy of the surface localized positron state on graphene and HOPG was estimated. The implication of our results regarding the applicability of AMPS and PAES to the study of graphene surfaces and interfaces will be discussed.

  12. Simulated crop yield in response to changes in climate and agricultural practices: results from a simple process based model

    Global agriculture will, in the future, be faced with two main challenges: climate change and an increase in global food demand driven by an increase in population and changes in consumption habits. To be able to predict both the impacts of changes in climate on crop yields and the changes in agricultural practices necessary to respond to such impacts we currently need to improve our understanding of crop responses to climate and the predictive capability of our models. Ideally, what we would have at our disposal is a modelling tool which, given certain climatic conditions and agricultural practices, can predict the growth pattern and final yield of any of the major crops across the globe. We present a simple, process-based crop growth model based on the assumption that plants allocate above- and below-ground biomass to maintain overall carbon optimality and that, to maintain this optimality, the reproductive stage begins at peak nitrogen uptake. The model includes responses to available light, water, temperature and carbon dioxide concentration as well as nitrogen fertilisation and irrigation. The model is data constrained at two sites, the Yaqui Valley, Mexico for wheat and the Southern Great Plains flux site for maize and soybean, using a robust combination of space-based vegetation data (including data from the MODIS and Landsat TM and ETM+ instruments), as well as ground-based biomass and yield measurements. We show a number of climate response scenarios, including increases in temperature and carbon dioxide concentrations as well as responses to irrigation and fertiliser application.

    A method is described for use with an acoustic positioner, which enables a determination of the equilibrium position and orientation which an object assumes in a zero gravity environment, as well as restoring forces and torques of an object in an acoustic standing wave field. An acoustic standing wave field is established in the chamber, and the object is held at several different positions near the expected equilibrium position. While the object is held at each position, the center resonant frequency of the chamber is determined, by noting which frequency results in the greatest pressure of the acoustic field. The object position which results in the lowest center resonant frequency is the equilibrium position. The orientation of a nonspherical object is similarly determined, by holding the object in a plurality of different orientations at its equilibrium position, and noting the center resonant frequency for each orientation. The orientation which results in the lowest center resonant frequency is the equilibrium orientation. Where the acoustic frequency is constant, but the chamber length is variable, the equilibrium position or orientation is that which results in the greatest chamber length at the center resonant frequency.

    Despite the availability of a growing range of interventions to assist control of body weight for people with excess weight or obesity, only a small proportion of people achieve their weight loss goals and are able to maintain body weight reductions in the long term. Negative attitudes and beliefs are often found among physicians and others involved in treating obesity and may adversely impact the effectiveness of management. In this international study, healthcare professionals were invited to complete an online survey of their attitudes and practice in the management of excess body weight. A total of 335 clinicians completed the survey of whom approximately half were based in Europe. A key finding from the survey is that, while participants are generally confident in their ability to manage overweight and obesity effectively, they also report that most of their patients are not successful in achieving their weight loss goals. At the same time, participants tended to overestimate the effectiveness of current medical management in maintaining reductions in body weight. Educational initiatives addressing the real-life effectiveness of different weight control interventions may help to close the gap between clinicians' perceptions and reality in the management of excess body weight.

    An individual’s motivational orientation serves as a drive to action and can influence their career success. This study examines how goal orientation toward the pursuit of a graduate degree in physics and chemistry influences later success outcomes of practicing physicists and chemists. Two main categories of goal orientation are examined in this paper: performance orientation or motivation to demonstrate one’s ability or performance to others, and learning orientation or motivation through the desire to learn about a topic. The data were obtained as part of Project Crossover, a mixed-methods study which focused on studying the transition from graduate student to scientist in the physical sciences and included a survey of members of two national professional physical science organizations. Using regression analysis on data from 2353 physicists and chemists, results indicate that physicists and chemists who reported a learning orientation as their motivation for going to graduate school were more productive, in terms of total career primary and/or first-author publications and grant funding, than those reporting a performance orientation. Furthermore, given equal salary, learning-oriented individuals produced more primary and/or first-author publications than their nonlearning oriented counterparts.

    The purpose of this research was to evaluate orienting messages within the CornerHouse Forensic Interview Protocol in two formats: provided both at the outset and as needed throughout the interview compared to previous practice in which orienting messages were provided only as the opportunity arose. Through the content analysis of 120 videotaped forensic interviews and corresponding case files in which children were interviewed for sexual abuse allegations, results suggest that the use of orienting messages both at the beginning and as needed lead to significantly more autonomous responses from children, that use of more orienting messages was significantly related to more autonomous responses from children, and that the specific orienting messages of "can't/won't say" and "ask me a question" significantly predict more autonomous responses among children. Implications for practice include the use of orienting messages as a way to provide a respectful and safe experience for children participating in forensic interviews. PMID:27561121

    2012-01-01

    Background We sought to investigate infant feeding practices amongst HIV-positive and -negative mothers (0-9 months postpartum) and describe the association between infant feeding practices and HIV-free survival. Methods Infant feeding data from a prospective observational cohort study conducted at three (of 18) purposively-selected routine South African PMTCT sites, 2002-2003, were analysed. Infant feeding data (previous 4 days) were gathered during home visits at 3, 5, 7, 9, 12, 16, 20, 24, 28, 32 and 36 weeks postpartum. Four feeding groups were of interest, namely exclusive breastfeeding, mixed breastfeeding, exclusive formula feeding and mixed formula feeding. Cox proportional hazards models were fitted to investigate associations between feeding practices (0-12 weeks) and infant HIV-free survival. Results Six hundred and sixty five HIV-positive and 218 HIV-negative women were recruited antenatally and followed-up until 36 weeks postpartum. Amongst mothers who breastfed between 3 weeks and 6 months postpartum, significantly more HIV-positive mothers practiced exclusive breastfeeding compared with HIV-negative: at 3 weeks 130 (42%) versus 33 (17%) (p < 0.01); this dropped to 17 (11%) versus 1 (0.7%) by four months postpartum. Amongst mothers practicing mixed breastfeeding between 3 weeks and 6 months postpartum, significantly more HIV-negative mothers used commercially available breast milk substitutes (p < 0.02) and use of these peaked between 9 and 12 weeks. The probability of postnatal HIV or death was lowest amongst infants living in the best resourced site who avoided breastfeeding, and highest amongst infants living in the rural site who stopped breastfeeding early (mean and standard deviations: 10.7% ± 3% versus 46% ± 11%). Conclusions Although feeding practices were poor amongst HIV-positive and -negative mothers, HIV-positive mothers undertake safer infant feeding practices, possibly due to counseling provided through the routine PMTCT programme.

    This study was to investigate and define what is considered as a current clinical practice in hemodynamic monitoring and vasoactive medication use after cardiac surgery in Italy. A 33-item questionnaire was sent to all intensive care units (ICUs) admitting patients after cardiac surgery. 71 out of 92 identified centers (77.2 %) returned a completed questionnaire. Electrocardiogram, invasive blood pressure, central venous pressure, pulse oximetry, diuresis, body temperature and blood gas analysis were identified as routinely used hemodynamic monitoring, whereas advanced monitoring was performed with pulmonary artery catheter or echocardiography. Crystalloids were the fluids of choice for volume replacement (86.8 % of Centers). To guide volume management, central venous pressure (26.7 %) and invasive blood pressure (19.7 %) were the most frequently used parameters. Dobutamine was the first choice for treatment of left heart dysfunction (40 %) and epinephrine was the first choice for right heart dysfunction (26.8 %). Half of the Centers had an internal protocol for vasoactive drugs administration. Intra-aortic balloon pump and extra-corporeal membrane oxygenation were widely available among Cardiothoracic ICUs. Angiotensin-converting enzyme inhibitors were suspended in 28 % of the Centers. The survey shows what is considered as standard monitoring in Italian Cardiac ICUs. Standard, routinely used monitoring consists of ECG, SpO2, etCO2, invasive BP, CVP, diuresis, body temperature, and BGA. It also shows that there is large variability among the various Centers regarding hemodynamic monitoring of fluid therapy and inotropes administration. Further research is required to better standardize and define the indicators to improve the standards of intensive care after cardiac surgery among Italian cardiac ICUs. PMID:26089166

    We present further steps developing an orientation indicator based on optical parameters that can be used for radio-quiet quasars. We recently demonstrated that the ratio of orientation-biased black hole mass calculated using the velocity width of Hbeta to the orientation-unbiased black hole mass calculated using the stellar velocity dispersion correlates with radio-loud orientation indicators, albeit with significant scatter. Our new work eliminates or reduces some sources of scatter to improve the significance of the correlation and to produce a better predictive prescription. Beyond biasing some mass measurements, orientation also affects luminosity determinations, and in turn estimates of the Eddington fraction, as well as luminosity functions, and other quasar properties. A practical radio-quiet orientation indicator for quasars is overdue.

    Person-oriented medicine is characterized by a holistic approach in patient ma- nagement that embraces physical, psychological, social and spiritual aspects of health and dise- ase. It responds to the needs of patients and health care workers to form an effective therapeutic relationship based on trust, empathy, compassion and responsiveness to the individual needs of a patient. Person-oriented perspectives in neurology include active collaborative partnership between a physician and a patient, and intuitive perception, which has a neurobiological correlate in the hu- man mirror neuron system, thus expressing a considerable impact on the quality of the physician's diagnostic and therapeutic activities. On the other hand, personalized approach in medicine implies integration of clinical information and personal genotyping. Personalized neurology provides gene- based preclinical prediction of disease with improved risk assessment, early detection of disease and targeted intervention. The combination of personalized approach and clinical information accelera- tes the translation of genetic discoveries into clinical practice, which ultimately results in improved health care system. Person-oriented perspectives contribute significantly to the growing pluralism of medical science and provide a greater humanization of medicine, individualized treatment and autonomy during therapeutic processes.

    A study was conducted to assess the effects of mortality salience on evaluations of political candidates as a function of leadership style. On the basis of terror management theory and previous research, we hypothesized that people would show increased preference for a charismatic political candidate and decreased preference for a relationship-oriented political candidate in response to subtle reminders of death. Following a mortality-salience or control induction, 190 participants read campaign statements by charismatic, task-oriented, and relationship-oriented gubernatorial candidates; evaluated their preferences for each candidate; and voted for one of them. Results were in accord with predictions. The theoretical and practical implications of these findings are considered. PMID:15563330

    Rupp, Madeline

    The following master's thesis is composed of two manuscripts describing STEM teachers' orientations to science teaching through engineering within the context of the Science Learning through Engineering Design (SLED) partnership. The framework guiding both studies was science teaching orientations, a component of pedagogical content knowledge. Data were collected via semi-structured interviews, multi-day classroom observations, pre- and post-observation interviews, implementation plans, and written reflections. Data sources were analyzed to generate two orientations to science teaching through engineering design for each participant. The first manuscript illustrates a single case study conducted with a sixth grade STEM teacher. Results of this study revealed a detailed picture of the teacher's goals, practices, assessments, and general views when teaching science through engineering design. Common themes across the teacher's instruction were used to characterize her orientations to science teaching through engineering design. Overall, the teacher's orientations showed a shift in her practice from didactic to student-centered methods of teaching as a result of integrating engineering design-based curriculum. The second manuscript describes a comparative case study of two sixth grade SLED participants. Results of this study revealed more complex and diverse relationships between the teachers' orientations to teaching science through engineering design and their instruction. Participants' orientations served as filters for instruction, guided by their divergent purposes for science teaching. Furthermore, their orientations and resulting implementation were developed from knowledge gained in teacher education, implying that teacher educators and researchers can use this framework to learn more about how teachers' knowledge is used to integrate engineering and science practices in the K-12 classroom.

    Background Canadian Community health nurses (CHNs) work in diverse urban, rural, and remote settings such as: public health units/departments, home health, community health facilities, family practices, and other community-based settings. Research into specific learning needs of practicing CHNs is sparsely reported. This paper examines Canadian CHNs learning needs in relation to the 2008 Canadian Community Health Nursing Standards of Practice (CCHN Standards). It answers: What are the learning needs of CHNs in Canada in relation to the CCHN Standards? What are differences in CHNs’ learning needs by: province and territory in Canada, work setting (home health, public health and other community health settings) and years of nursing practice? Methods Between late 2008 and early 2009 a national survey was conducted to identify learning needs of CHNs based on the CCHN Standards using a validated tool. Results Results indicated that CHNs had learning needs on 25 of 88 items (28.4%), suggesting CHNs have confidence in most CCHN Standards. Three items had the highest learning needs with mean scores > 0.60: two related to epidemiology (means 0.62 and 0.75); and one to informatics (application of information and communication technology) (mean = 0.73). Public health nurses had a greater need to know about “…evaluating population health promotion programs systematically” compared to home health nurses (mean 0.66 vs. 0.39, p <0.010). Nurses with under two years experience had a greater need to learn “… advocating for healthy public policy…” than their more experienced peers (p = 0.0029). Also, NPs had a greater need to learn about “…using community development principles when engaging the individual/community in a consultative process” compared to RNs (p = 0.05). Many nurses were unsure if they applied foundational theoretical frameworks (i.e., the Ottawa Charter of Health Promotion, the Jakarta Declaration, and the Population Health Promotion Model) in

    OBJECTIVE--To measure the change in cardiovascular risk factors achievable in families over one year by a cardiovascular screening and lifestyle intervention in general practice. DESIGN--Randomised controlled trial in 26 general practices in 13 towns in Britain. SUBJECTS--12,472 men aged 40-59 and their partners (7460 men and 5012 women) identified by household. INTERVENTION--Nurse led programme using a family centred approach with follow up according to degree of risk. MAIN OUTCOME MEASURES--After one year the pairs of practices were compared for differences in (a) total coronary (Dundee) risk score and (b) cigarette smoking, weight, blood pressure, and random blood cholesterol and glucose concentrations. RESULTS--In men the overall reduction in coronary risk score was 16% (95% confidence interval 11% to 21%) in the intervention practices at one year. This was partitioned between systolic pressure (7%), smoking (5%), and cholesterol concentration (4%). The reduction for women was similar. For both sexes reported cigarette smoking at one year was lower by about 4%, systolic pressure by 7 mm Hg, diastolic pressure by 3 mm Hg, weight by 1 kg, and cholesterol concentration by 0.1 mmol/l, but there was no shift in glucose concentration. Weight, blood pressure, and cholesterol concentration showed the greatest difference at the top of the distribution. If maintained long term the differences in risk factors achieved would mean only a 12% reduction in risk of coronary events. CONCLUSIONS--As most general practices are not using such an intensive programme the changes in coronary risk factors achieved by the voluntary health promotion package for primary care are likely to be even smaller. The government's screening policy cannot be justified by these results. PMID:8124121

    Lean Six Sigma process improvement methodologies have been used in manufacturing for some time. However, Lean Six Sigma process improvement methodologies also are applicable to radiology as a way to identify opportunities for improvement in patient care delivery settings. A multidisciplinary team of physicians and staff conducted a 100-day quality improvement project with the guidance of a quality advisor. By using the framework of DMAIC (define, measure, analyze, improve, and control), time studies were performed for all aspects of patient and technologist involvement. From these studies, value stream maps for the current state and for the future were developed, and tests of change were implemented. Comprehensive value stream maps showed that before implementation of process changes, an average time of 20.95 minutes was required for completion of a bone densitometry study. Two process changes (ie, tests of change) were undertaken. First, the location for completion of a patient assessment form was moved from inside the imaging room to the waiting area, enabling patients to complete the form while waiting for the technologist. Second, the patient was instructed to sit in a waiting area immediately outside the imaging rooms, rather than in the main reception area, which is far removed from the imaging area. Realignment of these process steps, with reduced technologist travel distances, resulted in a 3-minute average decrease in the patient cycle time. This represented a 15% reduction in the initial patient cycle time with no change in staff or costs. Radiology process improvement projects can yield positive results despite small incremental changes. PMID:20067999

    Objectives To ensure proper nutrition and optimal health outcomes, it is critical that infants are exclusively breastfed (0-6 months) and then receive adequate feeding from 6-23 months (breastfeeding and frequent feedings of complementary foods). Despite policies and guidelines on adequate feeding in Myanmar, past research has found low rates of adequately fed infants 0-11 months and little is known about the adequacy of feeding practices for children 12-23 months. The aim of this study is to understand the feeding practices of children aged 0-24 months in Myanmar and maternal characteristics associated with adequate feeding practices. Methods This study examines the rates of adequately fed infants and young children (0-23 months) in hard-to-reach townships in Myanmar from a cross-sectional, multistage cluster survey. Survey data on nutritional practices were collected from 489 mothers. Data were analyzed using multivariate regressions. Results We found that 41.8 % of infants under 6 months were exclusively breastfed, 63.2 % of those aged 6-11 months were adequately fed, and 10.3 % of 12-23 month-olds were adequately fed. In multivariate regressions we found that antenatal care visits [1-4 visits, AOR = 6.59 (p < 0.01) and >4 visits, AOR = 6.63 (p < 0.05)] was associated with exclusive breastfeeding for under 6 month old infants. Having >4 antenatal care visits [AOR = 9.97 (p < 0.05)] was associated with adequate feeding for 6-11 months old infants. Conclusions Future nutritional interventions and policies should focus on improving messaging about adequate feeding practices, especially for 12-23 months olds. PMID:27003151

    2015-01-01

    Background Given the amount of time and resources invested in implementing quality programs in hospitals, few studies have investigated their clinical impact and what strategies could be recommended to enhance its effectiveness. Objective To assess variations in clinical practice and explore associations with hospital- and department-level quality management systems. Design Multicenter, multilevel cross-sectional study. Setting and Participants Seventy-three acute care hospitals with 276 departments managing acute myocardial infarction, deliveries, hip fracture, and stroke in seven countries. Intervention None. Measures Predictor variables included 3 hospital- and 4 department-level quality measures. Six measures were collected through direct observation by an external surveyor and one was assessed through a questionnaire completed by hospital quality managers. Dependent variables included 24 clinical practice indicators based on case note reviews covering the 4 conditions (acute myocardial infarction, deliveries, hip fracture and stroke). A directed acyclic graph was used to encode relationships between predictors, outcomes, and covariates and to guide the choice of covariates to control for confounding. Results and Limitations Data were provided on 9021 clinical records by 276 departments in 73 hospitals. There were substantial variations in compliance with the 24 clinical practice indicators. Weak associations were observed between hospital quality systems and 4 of the 24 indicators, but on analyzing department-level quality systems, strong associations were observed for 8 of the 11 indicators for acute myocardial infarction and stroke. Clinical indicators supported by higher levels of evidence were more frequently associated with quality systems and activities. Conclusions There are significant gaps between recommended standards of care and clinical practice in a large sample of hospitals. Implementation of department-level quality strategies was significantly

    Aims To characterize patient radiation doses from nuclear myocardial perfusion imaging (MPI) and the use of radiation-optimizing ‘best practices’ worldwide, and to evaluate the relationship between laboratory use of best practices and patient radiation dose. Methods and results We conducted an observational cross-sectional study of protocols used for all 7911 MPI studies performed in 308 nuclear cardiology laboratories in 65 countries for a single week in March–April 2013. Eight ‘best practices’ relating to radiation exposure were identified a priori by an expert committee, and a radiation-related quality index (QI) devised indicating the number of best practices used by a laboratory. Patient radiation effective dose (ED) ranged between 0.8 and 35.6 mSv (median 10.0 mSv). Average laboratory ED ranged from 2.2 to 24.4 mSv (median 10.4 mSv); only 91 (30%) laboratories achieved the median ED ≤ 9 mSv recommended by guidelines. Laboratory QIs ranged from 2 to 8 (median 5). Both ED and QI differed significantly between laboratories, countries, and world regions. The lowest median ED (8.0 mSv), in Europe, coincided with high best-practice adherence (mean laboratory QI 6.2). The highest doses (median 12.1 mSv) and low QI (4.9) occurred in Latin America. In hierarchical regression modelling, patients undergoing MPI at laboratories following more ‘best practices’ had lower EDs. Conclusion Marked worldwide variation exists in radiation safety practices pertaining to MPI, with targeted EDs currently achieved in a minority of laboratories. The significant relationship between best-practice implementation and lower doses indicates numerous opportunities to reduce radiation exposure from MPI globally. PMID:25898845

    Stereovision based mobile mapping systems enable the efficient capturing of directly georeferenced stereo pairs. With today's camera and onboard storage technologies imagery can be captured at high data rates resulting in dense stereo sequences. These georeferenced stereo sequences provide a highly detailed and accurate digital representation of the roadside environment which builds the foundation for a wide range of 3d mapping applications and image-based geo web-services. Georeferenced stereo images are ideally suited for the 3d mapping of street furniture and visible infrastructure objects, pavement inspection, asset management tasks or image based change detection. As in most mobile mapping systems, the georeferencing of the mapping sensors and observations - in our case of the imaging sensors - normally relies on direct georeferencing based on INS/GNSS navigation sensors. However, in urban canyons the achievable direct georeferencing accuracy of the dynamically captured stereo image sequences is often insufficient or at least degraded. Furthermore, many of the mentioned application scenarios require homogeneous georeferencing accuracy within a local reference frame over the entire mapping perimeter. To achieve these demands georeferencing approaches are presented and cost efficient workflows are discussed which allows validating and updating the INS/GNSS based trajectory with independently estimated positions in cases of prolonged GNSS signal outages in order to increase the georeferencing accuracy up to the project requirements.

    Background. Complementary and alternative medicine (CAM) and integrative medicine (IM) modalities are widely used by patients, including those with infectious diseases (ID). Methods. One thousand randomly selected ID practitioners were surveyed. The survey was divided into domains related to familiarity and recommendation, beliefs and attitudes, and use of CAM/IM modalities. Results. The response rate was 31%. ID physicians were most familiar with vitamin and mineral supplementation (83%), massage (80%), acupuncture (79%), chiropractic (77%), yoga (74%), and herbal medicine (72%). ID physicians most recommended vitamin and mineral supplementation (80%) and massage (62%). Yoga, meditation, and acupuncture were recommended by 52%, 45%, and 46%, respectively. Drug interactions, clinical research, and knowledge of CAM/IM modalities were factors that were considered a major influence. Almost 80% of respondents indicated an interest in IM versus 11% for CAM. Most respondents (75%) felt that IM modalities are useful, and more than 50% believed that they could directly affect the immune system or disease process. Conclusion. ID physicians expressed a markedly greater interest for IM versus CAM. They appear to be familiar and willing to recommend some CAM/IM modalities and see a role for these in the management of certain infectious diseases. Data regarding clinical efficacy and safety appear to be important factors. PMID:23935658

    In recent years guidelines for the testing and treatment of osteoporotic patients have been published by recognised organisations, including the World Health Organisation (WHO), the National Osteoporosis Foundation (NOF) and the International Osteoporosis Foundation (IOF). Dual Energy X-ray Absorptiometry (DXA) has been considered the technique of choice because of its excellent precision and ability to predict osteoporotic fractures. Last December, based on the Appraisal of the Guidelines for Research and Evaluation (AGREE), the Hellenic Foundation of Osteoporosis, in collaboration with other scientific societies, provided guidelines for the use of DXA for the diagnosis, monitoring and treatment of osteoporosis and Quality Assurance (QA) of these systems. According to these guidelines, the adequacy of the present number of DXA units in Greece was assessed. There are 367 DXA units in Greece, and almost 50% are located in the capital city, Athens, where 34.1% of the population lives. The distribution of DXA devices per resident in the Greek provinces (except Attica) is between 4.2 units/100,000 heads (Ionian Islands) and 1.6 units/100,000 heads (Sterea Hellas). These guidelines have resulted in a suggestive yearly repeat of the measurements, to ensure the precision of the method, but mainly for reasons of compliance. Finally, these guidelines are viewed as a work in progress and will be updated periodically in response to advances in this field. PMID:16340144

    Please leave one line blank after the abstract. In a pure compression process, polymer melt is compressed to flow by moving the movable platen of the mold to complete melt filling. Compression of the melt is then continued by the pressure exerted from the mold wall of the core side. This process provides a more uniform pressure on the cavity wall and requires a lower molding pressure for the post-filling process. Since the fiber orientation distribution affects both the elastic properties of the finished part, it is important to know the influence in the development of shrinkage and warpage. This study introduces a true 3D finite volume based simulation tool to simulate the nonisothermal compression molding process with the fiber orientation prediction. For the compression action, a novel dynamic moving grid approach is adopted, where the computational domain will deform with time to realize the complex advancing flow front during compression. By means of simulation tool, the distribution of fiber orientation can be tailored through the interpolation of fiber orientation tensor and further investigate the effect of different initial orientation assignment in the pre-filled charge area. The results illustrate the potential practice of an effective 3D approach tool of being an extremely cost effective method to optimize the process.

    Background Prevention of unplanned pregnancies is a critical element in the prevention of mother-to-child transmission of HIV infection, but its potential has not been fully realized. We assessed the utilization of family planning (FP) and fertility desires among women of reproductive age by HIV status. Methods We selected a nationally representative sample of households using a stratified 2-stage cluster design and surveyed women aged 15–49 years. We administered questionnaires and examined predictors of current use of FP and desire for children among sexually active women with known HIV infection and women who were HIV uninfected. Results Of 3583 respondents, 68.2% were currently using FP, and 57.7% did not desire children in the future. Among women who did not desire children in the future, 70.9% reported that they were using FP, including 68.7% of women with known HIV infection and 71.0% of women who were HIV uninfected. Women with known HIV infection had similar odds of using FP as women with no HIV infection (odds ratio, 1.12; 95% confidence interval: 0.81 to 1.54). Women with no HIV infection had significantly higher adjusted odds of desiring future children (adjusted OR, 2.27; 95% confidence interval: 1.31 to 3.93) than women with known HIV infection. Conclusions There is unmet need for FP for HIV-infected women, underscoring a gap in the national prevention of mother-to-child transmission of HIV strategy. Efforts to empower HIV-infected women to prevent unintended pregnancies should lead to expanded access to contraceptive methods and take into account women’s reproductive intentions. PMID:24413040

    Backgound The number of patients with chronic gastrointestinal (GI) symptoms after cancer therapies which have a moderate or severe impact on quality of life is similar to the number diagnosed with inflammatory bowel disease annually. However, in contrast to patients with inflammatory bowel disease, most of these patients are not referred for gastroenterological assessment. Clinicians who do see these patients are often unaware of the benefits of targeted investigation (which differ from those required to exclude recurrent cancer), the range of available treatments and how the pathological processes underlying side effects of cancer treatment differ from those in benign GI disorders. This paper aims to help clinicians become aware of the problem and suggests ways in which the panoply of syndromes can be managed. Methods A multidisciplinary literature review was performed to develop guidance to facilitate clinical management of GI side effects of cancer treatments. Results Different pathological processes within the GI tract may produce identical symptoms. Optimal management requires appropriate investigations and coordinated multidisciplinary working. Lactose intolerance, small bowel bacterial overgrowth and bile acid malabsorption frequently develop during or after chemotherapy. Toxin-negative Clostridium difficile and cytomegalovirus infection may be fulminant in immunosuppressed patients and require rapid diagnosis and treatment. Hepatic side effects include reactivation of viral hepatitis, sinusoidal obstruction syndrome, steatosis and steatohepatitis. Anticancer biological agents have multiple interactions with conventional drugs. Colonoscopy is contraindicated in neutropenic enterocolitis but endoscopy may be life-saving in other patients with GI bleeding. After cancer treatment, simple questions can identify patients who need referral for specialist management of GI symptoms. Other troublesome pelvic problems (eg, urinary, sexual, nutritional) are frequent

    We perform a statistical study of Flux Transfer Event (FTE) orientations for different interplanetary magnetic field conditions to determine the location and orientation of reconnection lines on the dayside magnetopause. Our analysis is based on more than 200 estimations of FTE boundary normals and on determinations of the FTE orientations themselves. We perform Minimum Variance Analysis of the THEMIS magnetic field data within and in the vicinity of the FTE boundaries. We discuss the role of different reconnection processes on the orientation of FTEs. We pay special attention to cases in which different methods give conflicting results and cases in which the orientations differ from those predicted by the models.

  15. An international effort towards developing standards for best practices in analysis, interpretation and reporting of clinical genome sequencing results in the CLARITY Challenge

    PubMed Central

    2014-01-01

    Background There is tremendous potential for genome sequencing to improve clinical diagnosis and care once it becomes routinely accessible, but this will require formalizing research methods into clinical best practices in the areas of sequence data generation, analysis, interpretation and reporting. The CLARITY Challenge was designed to spur convergence in methods for diagnosing genetic disease starting from clinical case history and genome sequencing data. DNA samples were obtained from three families with heritable genetic disorders and genomic sequence data were donated by sequencing platform vendors. The challenge was to analyze and interpret these data with the goals of identifying disease-causing variants and reporting the findings in a clinically useful format. Participating contestant groups were solicited broadly, and an independent panel of judges evaluated their performance. Results A total of 30 international groups were engaged. The entries reveal a general convergence of practices on most elements of the analysis and interpretation process. However, even given this commonality of approach, only two groups identified the consensus candidate variants in all disease cases, demonstrating a need for consistent fine-tuning of the generally accepted methods. There was greater diversity of the final clinical report content and in the patient consenting process, demonstrating that these areas require additional exploration and standardization. Conclusions The CLARITY Challenge provides a comprehensive assessment of current practices for using genome sequencing to diagnose and report genetic diseases. There is remarkable convergence in bioinformatic techniques, but medical interpretation and reporting are areas that require further development by many groups. PMID:24667040

    Inappropriate complementary feeding practices have led to, in part, significant disparities in growth and nutritional status between rural and urban children in China. A cluster-randomised, controlled trial was implemented in Laishui, China to assess the effectiveness of an educational intervention on caregivers' feeding practices and children's growth. Eight townships were randomly assigned to the intervention or control. Five hundred ninety-nine healthy infants were enrolled at 2-4 months old, and were followed up at ages 6, 9, 12, 15 and 18 months. The intervention group received information on enhanced home-prepared recipes and food preparation and hygiene through group training, counselling and home visit. Key outcomes were children's physical growth, caregivers' knowledge and behaviours on complementary feeding, and the infant and child feeding index (ICFI). Analysis was by intention to treat. The intervention group achieved better knowledge and practices related to complementary feeding, and significantly higher ICFI scores at each follow-up point. Children in the intervention group achieved higher z-scores for weight-for-age (WAZ) and weight-for-height (WHZ) than the control (0.18 vs. 0.01 and 0.49 vs. 0.19, respectively) at 18 months old, and were less likely to have stunted growth (odds ratio = 0.71, 95% confidence interval: 0.53-0.94). Mixed model showed that the intervention group achieved significantly better linear growth over time, including WAZ (P = 0.016), WHZ (P = 0.030) and HAZ (P = 0.078). These results indicated that an educational intervention delivered through local health services can enhance caregivers' knowledge and practices of complementary feeding and ultimately improve children's growth.

    Objective: American data suggest a declining trend in the provision of psychotherapy by psychiatrists. Nevertheless, the extent to which such findings generalize to psychiatric practice in other countries is unclear. We surveyed psychiatrists in British Columbia to examine whether the reported decline in psychotherapy provision extends to the landscape of Canadian psychiatric practice. Method: A survey was mailed to the entire population of fully licensed psychiatrists registered in British Columbia (n = 623). The survey consisted of 30 items. Descriptive statistics were used to characterize the sample and psychotherapy practice patterns. Associations between variables were evaluated using nonparametric tests. Results: A total of 423 psychiatrists returned the survey, yielding a response rate of 68%. Overall, 80.9% of psychiatrists (n = 342) reported practicing psychotherapy. A decline in the provision of psychotherapy was not observed; in fact, there was an increase in psychotherapy provision among psychiatrists entering practice in the last 10 years. Individual therapy was the predominant format used by psychiatrists. The most common primary theoretical orientation was psychodynamic (29.9%). Regarding actual practice, supportive psychotherapy was practiced most frequently. Professional time constraints were perceived as the most significant barrier to providing psychotherapy. The majority (85%) of clinicians did not view remuneration as a significant barrier to treating patients with psychotherapy. Conclusions: Our findings challenge the prevailing view that psychotherapy is in decline among psychiatrists. Psychiatrists in British Columbia continue to integrate psychotherapy and pharmacotherapy in clinical practice, thus preserving their unique place in the spectrum of mental health services.

    Objectives To evaluate the implementation of four high evidence practices for the care of very preterm infants to assess their use and impact in routine clinical practice and whether they constitute a driver for reducing mortality and neonatal morbidity. Design Prospective multinational population based observational study. Setting 19 regions from 11 European countries covering 850 000 annual births participating in the EPICE (Effective Perinatal Intensive Care in Europe for very preterm births) project. Participants 7336 infants born between 24+0 and 31+6 weeks’ gestation in 2011/12 without serious congenital anomalies and surviving to neonatal admission. Main outcome measures Combined use of four evidence based practices for infants born before 28 weeks’ gestation using an “all or none” approach: delivery in a maternity unit with appropriate level of neonatal care; administration of antenatal corticosteroids; prevention of hypothermia (temperature on admission to neonatal unit ≥36°C); surfactant used within two hours of birth or early nasal continuous positive airway pressure. Infant outcomes were in-hospital mortality, severe neonatal morbidity at discharge, and a composite measure of death or severe morbidity, or both. We modelled associations using risk ratios, with propensity score weighting to account for potential confounding bias. Analyses were adjusted for clustering within delivery hospital. Results Only 58.3% (n=4275) of infants received all evidence based practices for which they were eligible. Infants with low gestational age, growth restriction, low Apgar scores, and who were born on the day of maternal admission to hospital were less likely to receive evidence based care. After adjustment, evidence based care was associated with lower in-hospital mortality (risk ratio 0.72, 95% confidence interval 0.60 to 0.87) and in-hospital mortality or severe morbidity, or both (0.82, 0.73 to 0.92), corresponding to an estimated 18% decrease

    Background Although minimally invasive surgery (MIS) has been quickly embraced, the introduction of advanced procedures appears more complex. We assessed the evolution of MIS in the province of Quebec over a 5-year period to identify areas for improvement in the modern surgical era. Methods We developed, test-piloted and conducted a self-administered questionnaire among Quebec general surgeons in 2007 and 2012 to examine stated MIS practice, MIS training and barriers and facilitators to the use of MIS. Results Response rates were 51.3% (251 of 489) in 2007 and 31.3% (153 of 491) in 2012. A significant increase was observed for performance of most advanced MIS procedures, especially for colectomy for benign (66.0% v. 84.3%, p < 0,001) and malignant diseases (43.3% v. 77.8%, p < 0,001) and for rectal surgery for malignancy (21.0% v. 54.6%, p < 0.001). More surgeons practised 3 or more advanced MIS procedures in 2012 than in 2007 (82.3% v. 64.3%, p < 0,001). At multivariate analysis, the 2007 survey administration was associated with fewer surgeons practising advanced MIS (odds ratio 0.13, 95% confidence interval 0.06–0.29). In 2012, more respondents stated they gained their skills during residency (p = 0.028). Conclusion From 2007 to 2012 there was a significant increase in advanced MIS procedures practised by general surgeons in Québec. This technique appears well established in current surgical practice. The growing place of MIS in residency training seems to be a paramount part of this development. Results from this study could be used as a baseline for studies focusing on ways to further improve the MIS practice. PMID:25598180

  20. Design oriented structural analysis

    1994-01-01

    Desirable characteristics and benefits of design oriented analysis methods are described and illustrated by presenting a synoptic description of the development and uses of the Equivalent Laminated Plate Solution (ELAPS) computer code. ELAPS is a design oriented structural analysis method which is intended for use in the early design of aircraft wing structures. Model preparation is minimized by using a few large plate segments to model the wing box structure. Computational efficiency is achieved by using a limited number of global displacement functions that encompass all segments over the wing planform. Coupling with other codes is facilitated since the output quantities such as deflections and stresses are calculated as continuous functions over the plate segments. Various aspects of the ELAPS development are discussed including the analytical formulation, verification of results by comparison with finite element analysis results, coupling with other codes, and calculation of sensitivity derivatives. The effectiveness of ELAPS for multidisciplinary design application is illustrated by describing its use in design studies of high speed civil transport wing structures.

  1. Review of the mechanism of cell death resulting from streptozotocin challenge in experimental animals, its practical use and potential risk to humans

    PubMed Central

    2013-01-01

    Streptozotocin (STZ) (2-deoxy-2-({[methyl(nitroso)amino]carbonyl}amino)-β-D-glucopyranose) is a naturally occurring diabetogenic compound, produced by the soil bacterium streptomyces achromogenes, that exhibits broad spectrum of antibacterial properties. Streptozotocin functions as a DNA synthesis inhibitor in both bacterial and mammalian cells. In mammalian cells, the actual mechanism and metabolic targets of STZ toxicity that results in cell death is not known. This review identifies four key areas that explain the mechanism of the cytotoxicity of STZ in mammalian cell lines, investigates the practical aspects of using STZ in experimental animals and the potential risks of its exposure to human health.

    The purpose of this To Be Verified/To Be Determined (TBX) resolution analysis is to release ''To Be Verified'' (TBV)-361 related to the emplacement drift orientation. The system design criterion in ''Subsurface Facility System Description Document'' (CRWMS M&O 1998a, p.9) specifies that the emplacement drift orientation relative to the dominant joint orientations should be at least 30 degrees. The specific objectives for this analysis include the following: (1) Collect and evaluate key block data developed for the repository host horizon rock mass. (2) Assess the dominant joint orientations based on available fracture data. (3) Document the maximum block size as a function of drift orientation. (4) Assess the applicability of the drift orientation/joint orientation offset criterion in the ''Subsurface Facility System Description Document'' (CRWMS M&O 1998a, p.9). (5) Consider the effects of seepage on drift orientation. (6) Verify that the viability assessment (VA) drift orientation complies with the drift orientation/joint orientation offset criterion, or provide justifications and make recommendations for modifying the VA emplacement drift layout. In addition to providing direct support to the System Description Document (SDD), the release of TBV-361 will provide support to the Repository Subsurface Design Department. The results from this activity may also provide data and information needs to support the MGR Requirements Department, the MGR Safety Assurance Department, and the Performance Assessment Organization.

  3. Late Triassic paleomagnetic result from the Baoshan Terrane, West Yunnan of China: Implication for orientation of the East Paleotethys suture zone and timing of the Sibumasu-Indochina collision

    2015-11-01

    In order to better understand the paleogeographic position of the Baoshan Terrane in the northernmost part of the Sibumasu Block during formation of the Pangea supercontinent, a paleomagnetic study has been conducted on Late Triassic basaltic lavas from the southern part of the Baoshan Terrane in the West Yunnan region of Southwest China. Following detailed rock magnetic investigations and progressive thermal demagnetization, stable characteristic remanent magnetizations (ChRMs) were successfully isolated from Late Triassic Niuhetang lava flows. The ChRMs are of dual polarity and pass fold and reversal tests with magnetic carriers dominated by magnetite and subordinate oxidation-induced hematite; we thus interpret them as a primary remanence. This new paleomagnetic result indicates that the Baoshan Terrane was located at low paleolatitudes of ∼15°N in the Northern Hemisphere during Late Triassic times. Together with available paleomagnetic data from the Baoshan Terrane and surrounding areas, a wider paleomagnetic comparison supports the view that the East Paleotethys Ocean separated the Sibumasu and Indochina blocks and closed no later than Late Triassic times. We argue that the currently approximately north-to-south directed Changning-Menglian suture zone is very likely to have been oriented nearly east-to-west at the time of the Sibumasu-Indochina collision.

    1979-07-01

    This article is based on the authors' book "Physician or Magician: The Myths and Realities of Patient Care" (McGraw Hill and Hemisphere, 1978). In this paper, the authors contend that the main problem confronting medical practice and medical education today is that there is no consensus on what physicians should be doing. Should they be technologists or should they be conceptually-oriented? The authors further state that these two types of physicians are trained in different approaches to problem solving. They conclude by saying that both types of physicians are needed if the quality of patient care is to improve while containing cost, but that the conceptually-oriented physician--the primary physician--should be in charge of all treatment patients receive. This is because the primary physicians as well as the Cartesian approach. Therefore, they would be better able to determine the risks and benefits to each patient of various technological regimens.

    Theoretical Background and Current Issues: For the sake of pre-emptive child protection it is necessary to recognise signs of postpartum depression (PPD) in pregnant women and young mothers as early as possible and to initiate adequate assistance. Because of their high acceptance, especially in the phases of pregnancy and birth, the local gynaecologists offer ideal prerequisites for access to the parents. This study evaluates the current status of diagnosis and management of PPD in gynaecological practices. Material and Methods: In a representative German nation-wide questionnaire survey taking the regional distribution into account n = 3000 local gynaecologists were selected at random and contacted by post. The questionnaire addressed their approaches to the diagnosis and management of PPD as well as the encountered barriers. Results: Among the n = 1034 participating gynaecologists (response rate: 35 %) half of them dealt actively with PPD; 16 % used a questionnaire for this purpose. Consultation by the gynaecologist (84 %) or referral to therapists or hospitals (86 %) were among the most common interventions in the management of PPD. A need for improvement in the management of women with PPD was recognised equally often. As barriers the gynaecologists mentioned above all the lack of time, the low reimbursements for consultations and the lack of effective treatment options. Predictors for an active anamnesis were found to be female gender of the gynaecologist, possession of an additional psychosomatic qualification and practice located in an urban catchment area or state of the former West Germany. Conclusion: The results clearly demonstrate a high acceptance for the management of PPD by gynaecologists as well as the need for further action to improve the care of patients with PPD in gynaecological practices.

    This article describes the development and evaluation of a national service to diagnose and remediate central auditory processing disorder (CAPD). Data were gathered from 38 participating Australian Hearing centers over an 18-month period from 666 individuals age 6, 0 (years, months) to 24, 8 (median 9, 0). A total of 408 clients were diagnosed with either a spatial processing disorder (n = 130), a verbal memory deficit (n = 174), or a binaural integration deficit (n = 104). A hierarchical test protocol was used so not all children were assessed on all tests in the battery. One hundred fifty clients decided to proceed with deficit-specific training (LiSN & Learn or Memory Booster) and/or be fitted with a frequency modulation system. Families were provided with communication strategies targeted to a child's specific listening difficulties and goals. Outcomes were measured using repeat assessment of the relevant diagnostic test, as well as the Client Oriented Scale of Improvement measure and Listening Inventories for Education teacher questionnaire. Group analyses revealed significant improvements postremediation for all training/management options. Individual posttraining performance and results of outcome measures also are discussed.

    Drawing upon achievement goal theory, this study explored the interplay between the perceived motivational climate, achievement goals and objective measurements of maximal oxygen uptake (VO2max). The results of a study of 123 individuals from three Norwegian military academies revealed that under the condition of a high-performance orientation there is a stronger positive relationship between performance climate and VO2max for individuals reporting a low (rather than high)-mastery orientation. Furthermore, we found that for individuals with a high-mastery orientation there is a stronger positive relationship between mastery climate and VO2max for individuals reporting a low (rather than high)-performance orientation. These findings contribute to achievement goal theory by providing support for an interactionist person-environment fit perspective. Implications for future research and practice are discussed.

    A survey of 813 mental health professionals serving adults with severe mental illness clustered in 25 community mental health centers assessed the extent to which mental health professionals possess clinical competencies that support recovery and the predictors of these competencies. The results suggest there is room for improvement in recovery-oriented competencies. In-depth professional training in recovery, greater job variety, more years practicing in mental health, participation on an intensive case management team, and perceptions of workplace recovery culture were predictors of recovery-oriented competencies. Prioritization of on-going professional, worker retention, and management strategies that incorporate a team approach to treatment and improvements in workplace recovery culture may potentially increase recovery-oriented clinical practice.

    Reich, M.; Heipke, C.

    2016-06-01

    In this paper we propose a novel workflow for the estimation of global image orientations given relative orientations between pairs of overlapping images. Our approach is convex and independent on initial values. First, global rotations are estimated in a relaxed semidefinite program (SDP) and refined in an iterative least squares adjustment in the tangent space of SO(3). A critical aspect is the handling of outliers in the relative orientations. We present a novel heuristic graph based approach for filtering the relative rotations that outperforms state-of-the-art robust rotation averaging algorithms. In a second part we make use of point-observations, tracked over a set of overlapping images and formulate a linear homogeneous system of equations to transfer the scale information between triplets of images, using estimated global rotations and relative translation directions. The final step consists of refining the orientation parameters in a robust bundle adjustment. The proposed approach handles outliers in the homologous points and relative orientations in every step of the processing chain. We demonstrate the robustness of the procedure on synthetic data. Moreover, the performance of our approach is illustrated on real world benchmark data.

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. In this report, we summarize the literature on technical reports and provide a model that depicts the transfer of federally funded aerospace R&D via the U.S. government technical report. We present results from our investigation of aerospace knowledge diffusion vis-a-vis the U.S. government technical communications practices of U.S. aerospace engineers and scientists affiliated with, not necessarily belonging to, the Society of Manufacturing Engineers (SME).

    2013-01-01

    Background To report results obtained by combining risk sharing tools with post-adoption surveillance mechanisms in order to control quality of care and implement a value-based reimbursement scheme for Neuro-reflexotherapy (NRT), a non-pharmacological treatment proven effective for neck pain (NP), thoracic pain (TP) and low back pain (LBP). Methods Pre-post prospective cohort study in routine clinical practice, carried out in primary care centers in the Spanish National Health Service in the Balearic Islands (Ib-Salut). Eight-hundred and seventy-one subacute and chronic NP, TP and LBP patients treated in Ib-Salut, who underwent NRT during 2011. A shared risk contract (SRC) was developed, where payments for NRT were linked to results on patients’ clinical evolution, reduction in medication and proportion of patients undergoing spinal surgery. Main outcome measures were local pain (NP, TP or LBP), referred pain, LBP-related disability and NP-related disability, measured using previously validated instruments at referral and 3 months later, use of medication assessed at referral and discharge, and rates of spinal surgery prescription after undergoing NRT. Results Median improvements at discharge corresponded to 57.1% of baseline value for local pain, 75.0% for referred pain, 53.8% for LBP-related disability and 45.0% for NP-related disability. Patients taking medication at discharge represented 29.0% of those taking it at referral. The proportion of patients in whom spinal surgery was prescribed after undergoing NRT was 0%. These results were consistent with those from previous randomised controlled trials (RCTs) and studies in routine practice, and complied with the standards set in the SRC. Conclusions It is feasible and effective to enhance post adoption surveillance methods with risk sharing tools to improve quality control and support value-based reimbursement decisions for NRT.

    Background. Upper respiratory tract infections (URTIs) are common in children. The cause of URTIs is usually viral, but parents' attitudes often contribute to inappropriate prescription of antibiotics, promoting antibiotic resistance. The objective of this study was to identify possible risk factors associated with antibiotic misuse in Greece, a country with high levels of antibiotic use and antibiotic resistance. Methods. A knowledge-attitude-practice (KAP) questionnaire was developed and distributed to Greek parents caring for children who were 5-6 years old, between January and July of the same school year. Results. The sample of the study contained 5312 parents from all geographic areas of Greece. The risk factors of being a father, having low education, having immigrant status, being a single parent, having low income, having <2 or >3 children, living in the islands, and being without experience in recurrent URTIs were significantly associated to inadequate knowledge, inappropriate attitudes, and wrong practices. Conclusions. This study has identified the main groups of parents that should be targeted in future intervention programs. PMID:23209933

    2007-06-01

    From the data of a multicentric investigation, performed in a French area (Alsace) using questionnaires filled by 800 geriatrics nurses, the author analyses their current knowledge and representations of Alzheimer's disease, their attitudes and practice concerning the disclosure of the diagnosis to the patients, and the influence of these data for the patients care. The results show three principal common aspects: first very important gaps, difficulties and contradictions concerning Alzheimer's disease knowledge; then heavy feelings of incompetence, loneliness, and therapeutic inanity with regard to the problems of their practice; last of all, their requests insisting on their need of information, formation, and aid, all missing for them. The nurses' language was devoid of specific and professional contents. It was similar to the general public, mediatic, and societal speeches, loaded with aprioristic assertions, reducing Alzheimer's disease to an organic process of humanity decline. This alarming picture calls to question its ground, mechanisms and solutions concerning the needs conveyed by the nurses, and the pertinency of the common concept of Alzheimer's disease. It enjoins to reconsider the nurses formation and a transdisciplinar further reflection about the notion of Alzheimer's disease and the messages which are transmitted by it. PMID:17556220

    2004-12-01

    Digital fingerprinting of multimedia data involves embedding information in the content signal and offers protection to the digital rights of the content by allowing illegitimate usage of the content to be identified by authorized parties. One potential threat to fingerprinting is collusion, whereby a group of adversaries combine their individual copies in an attempt to remove the underlying fingerprints. Former studies indicate that collusion attacks based on a few dozen independent copies can confound a fingerprinting system that employs orthogonal modulation. However, in practice an adversary is more likely to collude with some users than with other users due to geographic or social circumstances. To take advantage of prior knowledge of the collusion pattern, we propose a two-tier group-oriented fingerprinting scheme where users likely to collude with each other are assigned correlated fingerprints. Additionally, we extend our construction to represent the natural social and geographic hierarchical relationships between users by developing a more flexible tree-structure-based fingerprinting system. We also propose a multistage colluder identification scheme by taking advantage of the hierarchial nature of the fingerprints. We evaluate the performance of the proposed fingerprinting scheme by studying the collusion resistance of a fingerprinting system employing Gaussian-distributed fingerprints. Our results show that the group-oriented fingerprinting system provides the superior collusion resistance over a system employing orthogonal modulation when knowledge of the potential collusion pattern is available.

    Earth sand seas experience winds that blow with different strengths and from different directions in line with the seasons. In response, dune fields show a rich variety of shapes from small crescentic barchans to big star and linear dunes. Linear dunes often exhibit complex and compound patterns with different length scales and orientations, which seem difficult to relate to a single wind cycle. We present results of underwater experiments and numerical simulations where a single wind regime can lead to two different dunes orientation depending on sediment availability. Sediment availability selects the overriding mechanism for the formation of dunes: increasing in height from the destabilization of a sand bed or elongating in a finger on a non-erodible ground from a localized sand source. These mechanisms drive the dunes orientation. Therefore, dunes alignment maximizes dunes orthogonality to sand fluxes in the bed instability mode, while dunes are aligned with the sand transport direction in the fingering mode. Then, we derive a model for dunes orientation, which explains the coexistence of bedforms with different alignments and quantitatively predicts the orientation of dunes in Earth deserts. Finally, we explore the phase diagram and the stability of the fingering mode.

  20. Strong tilt illusions always reduce orientation acuity.

    The apparent spatial orientation of an object can differ from its physical orientation when differently oriented objects surround it. This is the "tilt illusion". Previously [Solomon, J. A., & Morgan, M. J. (2006). Stochastic re-calibration: Contextual effects on perceived tilt. Proceedings of the Royal Society of London. Series B, Biological Sciences, 273, 2681-2686], we reported a loss of orientation acuity whenever a large physical tilt was required to compensate for the tilt illusion and make a target appear horizontal. Since all of those targets appeared to be at least approximately horizontal, we concluded that orientation acuity was not wholly determined by the target's apparent orientation. In the present study, we used oblique (i.e. neither horizontal nor vertical) reference orientations to more directly examine the effect of perceived orientation on orientation acuity. The results show that when surround and reference were parallel, there was no tilt illusion and acuity was high. Acuity suffered whenever the tilt illusion caused a large discrepancy between the target's physical and perceived tilts. Since this was true even for tilted references, context-induced acuity loss cannot be simply an "oblique effect" of the target's physical orientation. PMID:19268684

    The transitive orientation problem is the problem of assigning a direction to each edge of a graph so that the resulting digraph is transitive. A graph is a comparability graph if such an assignment is possible. We describe an O(n + m) algorithm for the transitive orientation problem, where n and m are the number of vertices and edges of the graph; full details are given in. This gives linear time bounds for maximum clique and minimum vertex coloring on comparability graphs, recognition of two-dimensional partial orders, permutation graphs, cointerval graphs, and triangulated comparability graphs, and other combinatorial problems on comparability graphs and their complements.

    As organizations seek to better understand their customers, competitors, and environments, the marketing function effectively serves as the support mechanism for these activities in many industries. Accordingly, in many organizations the marketing concept has been elevated to the stature of a strategic weapon, manifested in the form of market orientation. Market-oriented firms emphasize the collection, organization, and dissemination of information regarding both customers and competitors. This strategy is especially well-suited for the health care industry where customer knowledge is of paramount importance, customer interaction is instantaneous, and customer satisfaction is essential. Results of a national study of general service hospitals suggest that firms which embrace a market orientation benefit through enhanced customer satisfaction and quality. PMID:10179668

    To date no instrument for the assessment of parenting styles is available in the German -language area that has been validated in patients with addictive disorders. Therefore the aim of this study was the confirmatory evaluation of the factor structure of the Questionnaire on Parental Attitudes and Rearing Practices (FEPS) in 186 alcohol dependent patients. The model as proposed by the test developers with the 4 factors Care, Autonomy, Low Punishment, and Low Material Reinforcement showed acceptable fit when residual correlations were allowed (mother: χ(2)/df=1,92, RMSEA=0,07, TLI=0,79; father: χ(2)/df=1,75, RMSEA=0,07, TLI=0,82). All factors showed sufficient factor reliabilities as well as good to very good internal consistencies. Factor loadings, discriminations and difficulties of the indicators could be regarded as good, with the exception of 2 items. These results indicate the factorial validity of the FEPS in patients with alcohol dependence. PMID:23446826

    2010-01-01

    This article revisits the debate about recent American torture practices, particularly the use of discredited anthropological texts to validate long-held Orientalist assumptions about the sexual vulnerability of Muslim males. Such practices are placed in an historical context of older imperial constructions of sexually deviant Muslims as well as of more general forms of gendered and sexual subordination required for war. American torturers intended to produce very particular objects of torture—ones willing and able to confess their 'true' orientation in terms of a binary hetero/homo sexual code established in 19th-century Europe. The torturers had the power to confirm through confession and re-enactment their crude assumptions, irrespective of the actual sexualities of those being tortured, with consequences for the transnational and reactionary politics of sexual identity.

    During IODP Expedition 319, the first riser-drilling borehole in ocean was penetrated by D/V CHIKYU at Site C0009 in the Nankai convergent margin, Japan. From 0 mbsf (meters below seafloor) to 1285 mbsf, the borehole crossed the Kumano forearc basin and from 1285 mbsf to the bottom depth of 1604 mbsf, the Nankai accretionary prism. In a short depth range of 84.20 m from 1509.7 to 1593.9 mbsf, core samples were retrieved by rotary core barrel drilling. We collected 3 whole-round core samples for measurements of anelastic strain recovery (ASR) by the same methods of sample preparation and anelastic strain data acquisition conducted in the previous Stage-1 expeditions of the same NanTroSEIZE drilling program (Byrne et al., 2009; GRL, Vol.36, L23310). Anelastic normal strains, measured every ten minutes in nine directions, including six independent directions, were used to calculate the anelastic strain tensors. All three samples showed coherent strain recovery over a long period more than 1 month. The three samples were from C0009A (3R,1531 mbsf; 4R, 1540 mbsf and 8R, 1577 mbsf, respectively) in lithologic Unit IV interpreted as accretionary prism or deformed slope sediments. All samples are composed of silty clays or hemipelagic muds with relatively high porosities (30%~). The ASR measurement results in Kumano Forearc Basin obtained from C0002 (Byrne et al., 2009) showed the maximum stress orientation is nearly vertical and a normal stress regime. However, the ASR results in the accretionary prism from C0009 show that the maximum principal stress axes plunge gently or are nearly horizontal and the stress regimes appear to be strike-slip or thrust (reverse fault) types.

    In traditional fMRI, individuals respond to exogenous stimuli and are naïve to the effects of the stimuli on their neural activity patterns. Changes arising in the fMRI signal are analyzed post-hoc to elucidate the spatial and temporal activation of brain regions associated with the tasks performed. The advent of real-time fMRI has enabled a new method to systematically alter brain activity across space and time using neurofeedback training (NFT), providing a new tool to study internally-driven processes such as neuroplasticity. In this work, we combined n-back practice with fMRI-NFT of the left dorsolateral prefrontal cortex (DLPFC) to better understand the relationship between open- and closed-loop neuromodulation. FMRI data were acquired during both traditional n-back and NFT across five imaging sessions. Region-of-interest (ROI) and voxel-wise 2 × 2 within subjects ANOVAs were carried out to determine the effects of, and interaction between, training session and neuromodulation type. A main effect of training session was identified for only a single, highly focused cluster that shared spatial properties with the fMRI-NFT target region (left DLPFC). This finding indicates that combined open- and closed-loop neuroplastic enhancement techniques result in focal changes that are confined to the target area of NFT, and do not affect up- or down-stream network components that are normally engaged during working memory. Additionally, we identified a main effect of neuromodulation type for 15 clusters with significantly different activation between open- and closed-loop neuromodulation during training, 12 of which demonstrated higher activity during the open-loop neuromodulation. Our results, taken together with previous reports, indicate that fMRI-NFT combined with n-back practice leads to a highly focal volume exhibiting neuroplasticity without additional network effects.

    Introduction The European League Against Rheumatism (EULAR) recommendations for the management of rheumatoid arthritis (RA) and the treat-to-target (T2T) principles have been developed in order to improve the treatment outcome of patients with RA, and have received broad attention. It is not clear, though, whether these recommendations are indeed followed up in clinical practice. Objective To investigate if rheumatologists that report to agree with existing guidelines indeed follow them up in clinical practice. Methods The International Recommendation Implementation Study (IRIS) included 132 participating rheumatologists from 14 countries. Participating rheumatologists received a questionnaire measuring their awareness/commitment with the EULAR/T2T recommendations and followed a dedicated educational programme. Subsequently, they were asked to enrol 5–10 patients with new-onset RA in the online IRIS database and monitor disease activity and treatment for a period of 1–2 years. Four recommendations (3 from the EULAR recommendations and one from the T2T recommendations) were selected on the basis of testability, and analysed with regard to compliance by participating rheumatologists. Results In total, 72 of the 132 participating rheumatologists contributed 378 patients to the database. Of these participants, 70 (98%) agreed upfront with the recommendation that disease-modifying antirheumatic drug (DMARD) therapy should be started as soon as possible after diagnosis in every patient; 69 (96%) of the rheumatologists agreed with the recommendation that methotrexate (MTX) should be part of the first treatment strategy. When measuring the actual performance, it was found that the recommendation on early DMARD start was met in 253 (67%) of the recorded patients, and the recommendation on MTX in 225 (60%) of the recorded patients. Of the participants, 60 (83%) agreed that composite measures should be recorded regularly, but only in 134(54%) of the patients were

    2016-09-01

    Genetic testing can be used to determine if unexplained fractures in children could have resulted from a predisposition to bone fractures, e.g., osteogenesis imperfecta. However, uncertainty is introduced if a variant of unknown significance (VUS) is identified. Proper interpretation of VUS in these situations is critical because of its influence on clinical care and in court rulings. This study sought to understand how VUS are interpreted and used by practitioners when there is a differential diagnosis including both osteogenesis imperfecta and non-accidental injury.A 15-question survey was emailed to physicians who requested analysis of two genes, COL1A1 and COL1A2, from the University of Washington from 2005-2013 for patient cases involving suspicion of child abuse.Among the 89 participants, responses differed about when genetic testing should be ordered for osteogenesis imperfecta, who should be consulted about utilization of VUS test results, follow-up procedures, and who should receive the VUS results.There are no clear guidelines for how to interpret and follow up on VUS. In the legal setting, misinterpreted VUS could lead to unintended consequences and deleterious ramifications for family members. The need for better practice guidelines to help promote more equitable handling of these sensitive legal cases is clear. PMID:27587455

    Purpose: Social media and mobile technology are transforming the way in which young physicians are learning and practicing medicine. The true impact of such technologies has yet to be evaluated. Methods and Materials: We performed a nationwide cross-sectional survey to better assess how young radiation oncologists used these technologies. An online survey was sent out between April 24, 2013, and June 1, 2013. All residents attending the 2013 radiation oncology French summer course were invited to complete the survey. Logistic regressions were performed to assess predictors of use of these tools in the hospital on various clinical endpoints. Results: In all, 131 of 140 (93.6%) French young radiation oncologists answered the survey. Of these individuals, 93% owned a smartphone and 32.8% owned a tablet. The majority (78.6%) of the residents owning a smartphone used it to work in their department. A total of 33.5% had more than 5 medical applications installed. Only 60.3% of the residents verified the validity of the apps that they used. In all, 82.9% of the residents had a social network account. Conclusions: Most of the residents in radiation oncology use their smartphone to work in their department for a wide variety of tasks. However, the residents do not consistently check the validity of the apps that they use. Residents also use social networks, with only a limited impact on their relationship with their patients. Overall, this study highlights the irruption and the risks of new technologies in the clinical practice and raises the question of a possible regulation of their use in the hospital.

    Using cross-sectional and longitudinal data from expatriates in China, the authors investigated the roles of general, work, and interaction adjustment, as well as work stress, as mediators between the antecedents (learning, proving, and avoiding goal orientations, and perceived organizational support) and expatriate outcome (job performance and premature return intention) relationships. Results indicated that goal orientations toward overseas assignments had differential relationships with expatriate job performance and premature return intention. In addition, it was found that these relationships were partially mediated by expatriate adjustment facets. Implications for expatriate adjustment research and practice are discussed. PMID:17845096

    A source-oriented Community Multiscale Air Quality (CMAQ) model driven by the meteorological fields generated by the Weather Research and Forecasting (WRF) model was used to study the dry and wet deposition of nitrate (NO3(-)), sulfate (SO4(2-)), and ammonium (NH4(+)) ions in the Jiuzhaigou National Nature Reserve (JNNR), China from June to August 2010 and to identify the contributions of different emission sectors and source regions that were responsible for the deposition fluxes. The model performance is evaluated in this paper and the source contribution analyses are presented in a companion paper. The results show that WRF is capable of reproducing the observed precipitation rates with a Mean Normalized Gross Error (MNGE) of 8.1%. Predicted wet deposition fluxes of SO4(2-) and NO3(-) at the Long Lake (LL) site (3100 m a.s.l.) during the three-month episode are 2.75 and 0.34 kg S(N) ha(-1), which agree well with the observed wet deposition fluxes of 2.42 and 0.39 kg S(N) ha(-1), respectively. Temporal variations in the weekly deposition fluxes at LL are also well predicted. Wet deposition flux of NH4(+) at LL is over-predicted by approximately a factor of 3 (1.60 kg N ha(-1)vs. 0.56 kg N ha(-1)), likely due to missing alkaline earth cations such as Ca(2+) in the current CMAQ simulations. Predicted wet deposition fluxes are also in general agreement with observations at four Acid Deposition Monitoring Network in East Asia (EANET) sites in western China. Predicted dry deposition fluxes of SO4(2-) (including gas deposition of SO2) and NO3(-) (including gas deposition of HNO3) are 0.12 and 0.12 kg S(N) h a(-1) at LL and 0.07 and 0.08 kg S(N) ha(-1) at Jiuzhaigou Bureau (JB) in JNNR, respectively, which are much lower than the corresponding wet deposition fluxes. Dry deposition flux of NH4(+) (including gas deposition of NH3) is 0.21 kg N ha(-1) at LL, and is also much lower than the predicted wet deposition flux. For both dry and wet deposition fluxes, predictions

  4. Aesthetic judgement of orientation in modern art.

    2012-01-01

    When creating an artwork, the artist makes a decision regarding the orientation at which the work is to be hung based on their aesthetic judgement and the message conveyed by the piece. Is the impact or aesthetic appeal of a work diminished when it is hung at an incorrect orientation? To investigate this question, Experiment 1 asked whether naïve observers can appreciate the correct orientation (as defined by the artist) of 40 modern artworks, some of which are entirely abstract. Eighteen participants were shown 40 paintings in a series of trials. Each trial presented all four cardinal orientations on a computer screen, and the participant was asked to select the orientation that was most attractive or meaningful. Results showed that the correct orientation was selected in 48% of trials on average, significantly above the 25% chance level, but well below perfect performance. A second experiment investigated the extent to which the 40 paintings contained recognisable content, which may have mediated orientation judgements. Recognition rates varied from 0% for seven of the paintings to 100% for five paintings. Orientation judgements in Experiment 1 correlated significantly with "meaningful" content judgements in Experiment 2: 42% of the variance in orientation judgements in Experiment 1 was shared with recognition of meaningful content in Experiment 2. For the seven paintings in which no meaningful content at all was detected, 41% of the variance in orientation judgements was shared with variance in a physical measure of image content, Fourier amplitude spectrum slope. For some paintings, orientation judgements were quite consistent, despite a lack of meaningful content. The origin of these orientation judgements remains to be identified. PMID:23145264

    Purpose This article presents a comparison of the effectiveness of traditional clinical education toward skill acquisition goals versus simulation-based medical education (SBME) with deliberate practice (DP). Method This is a quantitative meta-analysis that spans twenty years, 1990 to 2010. A search strategy involving three literature databases, 12 search terms, and four inclusion criteria was used. Four authors independently retrieved and reviewed articles. Main outcome measures were extracted to calculate effect sizes. Results Of 3,742 articles identified, 14 met inclusion criteria. The overall effect size for the 14 studies evaluating the comparative effectiveness of SBME compared to traditional clinical medical education was 0.71 (95% confidence interval, 0.65–0.76; P < .001). Conclusions Although the number of reports analyzed in this meta analysis is small, these results show that SBME with DP is superior to traditional clinical medical education in achieving specific clinical skill acquisition goals. SBME is a complex educational intervention that should be introduced thoughtfully and evaluated rigorously at training sites. Further research on incorporating SBME with DP into medical education is needed to amplify its power, utility, and cost-effectiveness. PMID:21512370

  6. Using partial sensor information to orient parts

    Akella, S.; Mason, M.T.

    1999-10-01

    Parts orienting, the process of bringing parts in initially unknown orientations to a goal orientation, is an important aspect of automated assembly. The most common industrial orienting systems are vibratory bowl feeders, which use the shape and mass properties of parts to orient them. Bowl feeders rely on a sequence of mechanical operations and typically do not use sensors. In this paper, the authors describe the use of partial information sensors along with a sequence of pushing operations to eliminate uncertainty in the orientation of parts. The authors characterize the shorter execution lengths of sensor-based plans and show that sensor-based plans are more powerful than sensorless plans in that they can bring a larger class of parts to distinct orientations. The authors characterize the relation among part shape, orientability; and recognizability to identify conditions under which a single plan can orient and recognize multiple part shapes. Although part shape determines the results of the actions and the sensed information, the authors establish that differences in part shape do not always lead to differences in part behavior. The authors show that for any convex polygon, there exists an infinite set of nonsimilar convex polygons that behave identically under linear normal pushes. Furthermore, there exists a infinite set of nonsimilar convex polygons whose behavior cannot be distinguished even with diameter sensing after each push. They authors have implemented several planners and demonstrated generated plans in experiments.

    2013-04-01

    The present study examined the effectiveness of the Guilty Action Test in detecting critical information from goal-oriented and task-oriented informed innocent examinees. A mock crime procedure was employed and informed innocent participants were either motivated to prove innocence (goal-oriented motivation) or to prove innocence by being cooperative on the test (task-oriented motivation). Half of the participants in each motivation condition were promised course credit reward for successful completion of their mission to prove innocence or to be cooperative (high incentive level). The other half were promised no reward (low incentive level). A fifth group of uninformed innocent participants served for control purposes. Electrodemal, respiration, and cardiovascular measures were used to indicate the motivation effects. Results showed that the combination of goal-oriented instructions and an incentive for success contributed to enhanced responses to the crime-related information. The combination of task-oriented instructions and an incentive for success attenuated these responses. Skin conductance responses were most sensitive to these effects. Theoretical and practical aspects of the results were discussed. PMID:23458884

  8. Orientation-independent measures of ground motion

    Boore, D.M.; Watson-Lamprey, Jennie; Abrahamson, N.A.

    2006-01-01

    The geometric mean of the response spectra for two orthogonal horizontal components of motion, commonly used as the response variable in predictions of strong ground motion, depends on the orientation of the sensors as installed in the field. This means that the measure of ground-motion intensity could differ for the same actual ground motion. This dependence on sensor orientation is most pronounced for strongly correlated motion (the extreme example being linearly polarized motion), such as often occurs at periods of 1 sec or longer. We propose two new measures of the geometric mean, GMRotDpp, and GMRotIpp, that are independent of the sensor orientations. Both are based on a set of geometric means computed from the as-recorded orthogonal horizontal motions rotated through all possible non-redundant rotation angles. GMRotDpp is determined as the ppth percentile of the set of geometric means for a given oscillator period. For example, GMRotDOO, GMRotD50, and GMRotD100 correspond to the minimum, median, and maximum values, respectively. The rotations that lead to GMRotDpp depend on period, whereas a single-period-independent rotation is used for GMRotIpp, the angle being chosen to minimize the spread of the rotation-dependent geometric mean (normalized by GMRotDpp) over the usable range of oscillator periods. GMRotI50 is the ground-motion intensity measure being used in the development of new ground-motion prediction equations by the Pacific Earthquake Engineering Center Next Generation Attenuation project. Comparisons with as-recorded geometric means for a large dataset show that the new measures are systematically larger than the geometric-mean response spectra using the as-recorded values of ground acceleration, but only by a small amount (less than 3%). The theoretical advantage of the new measures is that they remove sensor orientation as a contributor to aleatory uncertainty. Whether the reduction is of practical significance awaits detailed studies of large

    Introduction There is a growing demand on our health care system, including Dentistry, to shift from a bio-medical approach to Integrative model of care. The attitudes of health professionals towards Integrative Medicine (IM) are an important factor that influences this transition. Aim The aim of this study was to evaluate and compare the orientation of the dental professionals in India towards the principles and practice of Integrative Medicine. Materials and Methods A cross-sectional survey was conducted on 286 dental faculty and postgraduate students from three dental schools in India. The participants voluntarily and anonymously completed the “Integrative Medicine-30’ questionnaire, a 30 item self-report instrument that measures the health care provider’s orientation towards Integrative Medicine in five subscales. Data analysis included summary statistics and intergroup comparisons by gender and professional status with independent samples Mann-Whitney U test. Results The overall orientation of the dental professionals towards IM was almost neutral. While the use of learning resources on Complementary and Alternative Medicine was lower, they showed a more positive orientation towards patient-centred care. Compared to postgraduate students of Dentistry, the dental faculty were more oriented towards IM (median score of 82 vs. 79.5, p<0.01), especially in terms of learning from alternate paradigms (14 vs. 12, p<0.01) and safety of Complementary and Alternative Medicine (13 vs. 12, p<0.01). Females scored better than males both in terms of overall orientation (82 vs. 78, p<0.01) and towards patient-centred care (12 vs. 11, p<0.001). Conclusion The results highlight the impending need to improve the orientation of dental professionals in India towards the principles and practice of IM. PMID:27042588

    Objective Selective serotonin reuptake inhibitors are commonly used in the pharmacotherapy of depression. However, adverse events can lead to their early discontinuation. This study evaluated the safety and effectiveness of paroxetine controlled-release (CR) tablets in Japanese patients with depression/depressive state (hereafter referred to as depression) in routine clinical practice in Japan. Patients and methods This was an open-label, noninterventional, prospective, postmarketing surveillance study. A total of 3,213 patients aged 12–92 years with depression were prescribed paroxetine CR for 8 weeks at the physician’s discretion. Safety was evaluated on the basis of the reporting of adverse drug reactions. Effectiveness was evaluated on the basis of the physician’s assessment using the Clinical Global Impression-Global Improvement (CGI-GI) and the Clinical Global Impression-Severity of Illness (CGI-SI) scales, as well as on the basis of the patients’ self-reported satisfaction. The primary effectiveness outcome was the improvement rate based on the physician’s assessment using the CGI-GI. Results The incidence of adverse drug reactions was 11.2% (359/3,213; 95% confidence interval [CI]: 10.1%–12.3%). The common adverse drug reactions that accounted for 1.0% or more of the incidence were nausea (3.5%) and somnolence (2.7%). The proportion of patients who continued paroxetine CR at week 8 was 80.2% (2,577/3,213; 95% CI: 78.8%–81.6%). The improvement rate at week 8 (last observation carried forward) was 72.8% (2,132/2,927; 95% CI: 71.2%–74.4%). The proportion of patients with CGI-SI scores of moderately or severely ill decreased from 63.6% at baseline to 17.9% at week 8. The proportion of patients who were satisfied with paroxetine CR treatment was 69.8% (2,040/2,921; 95% CI: 68.1%–71.5%). Conclusion The results of this study suggest that paroxetine CR is a well-tolerated and efficacious treatment for depression in routine clinical practice. PMID

  14. Orientation of Hittite Monuments

    The possible astronomical or topographical orientations of the Hittite monuments of the Bronze Age has remained unexplored until recently. This would provide an important insight into how temporality was imprinted by this culture in sacred spaces and in the landscape. The authors' analysis of a statistically significant sample of Hittite temples - and a few monumental gates - has demonstrated that ancient Hittite monuments were not randomly orientated as previously thought. On the contrary, there were well-defined patterns of orientation that can be interpreted within the context of Hittite culture and religion.

    The links between youth's daily activities and adjustment and the role of cultural practices and values in these links were studied in 469 youth from 237 Mexican American families. In home interviews, data on mothers', fathers', and two adolescent-age siblings' cultural practices (language use, social contacts) and values (for familism, for education achievement) were collected, along with data on youth risky behavior and depressive symptoms. In 7 nightly phone calls, youth reported on their day's free time activities (i.e., sports, academics, religious activities, television viewing, and hanging out). Analyses revealed that youth who spent more time in unsupervised hanging out reported more depressive symptoms and risky behavior, and those who spent more time in academic activities reported less risky behavior. Results also indicated that more Anglo-oriented youth spent more time in sports, that more Mexican-oriented youth spent more time watching television, that fathers' familism values were related to youth's time in religious activities, and that parents' educational values were linked to youth's time in academic activities. Some evidence indicated that parents' cultural practices and values, particularly fathers', moderated the links between daily activities and youth adjustment. PMID:19636760

  16. Optimization procedures for the estimation of phase portrait parameters of orientation fields

    Oriented patterns in an image often convey important information regarding the scene or the objects contained. Given an image presenting oriented texture, the orientation field of the image is a map that depicts the orientation angle of the texture at each pixel. Rao and Jain developed a method to describe oriented patterns in an image based on the association between the orientation field of a textured image and the phase portrait generated by a pair of linear first-order differential equations. The estimation of the model parameters is a nonlinear, nonconvex optimization problem, and practical experience shows that irrelevant local minima can lead to convergence to inappropriate results. We investigated the performance of four optimization algorithms for the estimation of the optimal phase portrait parameters for a given orientation field. The investigated algorithms are: nonlinear least-squares, linear least-squares, iterative linear least-squares, and simulated annealing. The algorithms are evaluated and compared in terms of the error between the estimated parameters and the parameters known by design, in the presence of noise in the orientation field and imprecision in the initialization of the parameters. The computational effort required by each algorithm is also assessed. Individually, the simulated annealing procedure yielded low fixed-point and parameter errors over the entire range of noise tested, whereas the performance of the other methods deteriorated with higher levels of noise. The use of the result of simulated annealing for the initialization of the nonlinear least-squares method led to further improvement upon the simulated annealing results.

    One of the key motivations in producing 3D structures has always been the realization of metamaterials with effective constituent properties that can be tuned in all propagation directions at various frequencies. Here, we report the investigation of spatially oriented "Nanograter" structures with orientation-dependent responses over a wide spectrum by focused-ion-beam based patterning and folding of thin film nanostructures. Au nano units of different shapes, standing along specifically designated orientations, were fabricated. Experimental measurements and simulation results show that such structures offer an additional degree of freedom for adjusting optical properties with the angle of inclination, in additional to the size of the structures. The response frequency can be varied in a wide range (8 μm-14 μm) by the spatial orientation (0°-180°) of the structures, transforming the response from magnetic into electric coupling. This may open up prospects for the fabrication of 3D nanostructures as optical interconnects, focusing elements and logic elements, moving toward the realization of 3D optical circuits.

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

    An apparatus that can return a payload to a known orientation after unknown motion, without requiring external power or complex mechanical systems. The apparatus comprises a faceted cage that causes the system to rest in a stable position and orientation after arbitrary motion. A gimbal is mounted with the faceted cage and holds the payload, allowing the payload to move relative to the stable faceted cage. The payload is thereby placed in a known orientation by the interaction of gravity with the geometry of the faceted cage, the mass of the system, and the motion of the payload and gimbal. No additional energy, control, or mechanical actuation is required. The apparatus is suitable for use in applications requiring positioning of a payload to a known orientation after arbitrary or uncontrolled motion, including remote sensing and mobile robot applications.

    The German Society for Cardiac Angiography and Interventions in Private Practice has started a registry of cardiac procedures since 1996 in order to establish a standard for performance. Although quality management for the cath lab makes sense and is also legally required, there is no generally recommended infrastructure for quality assurance existing in Germany at this time. Therefore, the German Society of Cardiologists in Private Practice (BNK) initiated a project in 1994 to develop a computer program for paperless documentation of diagnostic cardiac catheterizations and coronary interventions (PTCA) using a minimal data set. In 1996, 8 private associated groups participated in this project. The (anonymous) analysis of 10,316 diagnostic cardiac catheterizations and 2597 PTCA yielded the following results: In 95% of the patients, diagnostic cardiac catheterization was performed using the femoral and in 5% the brachial/radial approach. The mean volume of administered contrast medium was 164 +/- 138 ml/patient. The mean LV-EF was greater than 50% in 58.4% of the patients and between 30% and 50% in 10.1%. Coronary artery disease was diagnosed in 69.6% of the patients and valvular/congenital heart disease in 8.5%. In 18.4% of the patients undergoing diagnostic cardiac catheterizations no significant heart disease was identified. Mortality in the cath lab as well as the rate of cerebral insults was 0.05%. In 22.9% and 19% of the patients PTCA and cardiac surgery respectively was recommended. In patients undergoing PTCA, stable angina was present in 74.4% and unstable angina in 13.1%. Of the total number of PTCA procedures, 5.8% were performed in the setting of acute myocardial infarction. The PTCA lesion success rate was 96%, the mean diameter stenosis was 81% pre and 6% post-intervention. The mortality rate at 1 month post-PTCA was 0.4%, and myocardial infarction 1.0%. An acute occlusion occurred in 1.3% of the PTCA patients; 0.6% had to be transferred for emergency

    Background Effective strategies to address risk factors of non-communicable diseases are required to curtail the expanding costs of health care. This trial tested the effectiveness over one year of a minimal intervention targeting multiple health behaviours (diet, physical activity, alcohol and smoking) in a general practice setting, through the provision of personalised, computer-tailored feedback. Methods Patients who had attended a general practice in the previous 6 months were recruited from 21 general practitioners in Brisbane, Australia. Baseline data were collected using self-reports on adherence to ten health behaviours and summarised into a health score from 0 to 10. This randomised controlled trial used a 2×2 factorial design, with one arm randomising subjects to the intervention or control group. The other arm was either feedback at baseline (single contact) or an additional assessment with feedback at 3 months (dual contact). As such, 4 study groups created were, to which participants were randomised blindly: A. Intervention with single contact; B. Intervention with dual contact; C. Control with single contact and D. Control with dual contact. All participants were assessed again at 12 months. Results Of the 4676 participants randomised, 3065 completed questionnaires at 12 months. Both single and dual contact groups improved their 10 item health scores (+0.31 and +0.49 respectively) relative to control group outcomes (+0.02; p < 0.01). Improvement in adherence to guidelines for fish intake, type of milk consumed, vegetable and fruit intake, and alcohol intake were observed in single and dual contact intervention groups (p < 0.01). Both intervention groups showed greater improvement than controls for individual health behaviours, apart from red meat intake, smoking behaviour, physical activity and body weight. Interestingly, there was an improvement in reported non-smoking rates in both intervention and control groups (3% single contact; 4

    Identifying latent fingerprints is of vital importance for law enforcement agencies to apprehend criminals and terrorists. Compared to live-scan and inked fingerprints, the image quality of latent fingerprints is much lower, with complex image background, unclear ridge structure, and even overlapping patterns. A robust orientation field estimation algorithm is indispensable for enhancing and recognizing poor quality latents. However, conventional orientation field estimation algorithms, which can satisfactorily process most live-scan and inked fingerprints, do not provide acceptable results for most latents. We believe that a major limitation of conventional algorithms is that they do not utilize prior knowledge of the ridge structure in fingerprints. Inspired by spelling correction techniques in natural language processing, we propose a novel fingerprint orientation field estimation algorithm based on prior knowledge of fingerprint structure. We represent prior knowledge of fingerprints using a dictionary of reference orientation patches. which is constructed using a set of true orientation fields, and the compatibility constraint between neighboring orientation patches. Orientation field estimation for latents is posed as an energy minimization problem, which is solved by loopy belief propagation. Experimental results on the challenging NIST SD27 latent fingerprint database and an overlapped latent fingerprint database demonstrate the advantages of the proposed orientation field estimation algorithm over conventional algorithms.

    Recovery-oriented mental health services promote the principles of recovery, such as hope and optimism, and are characterized by a personalized approach to developing consumer self-determination. Nurse leaders are increasingly developing such services as social enterprises, but there is limited research on the leadership of these programs. Leading a recovery-oriented mental health nurse social enterprise requires visionary leadership, collaboration with consumers and local health providers, financial viability, and commitment to recovery-focused practice. This article describes the framework of an Australian mental health nursing social enterprise, including the service attributes and leadership lessons that have been learned from developing program sustainability.

    Preliminary results of the Polish epidemiology study on eye lens opacities among interventional cardiologists (ICs), based on the methodology proposed by ELDO (epidemiological studies of radio-induced cataracts in interventional cardiologists and radiologists: methodology implementation), are presented. The aim of the study is to test the hypothesis concerning the excess risk of cataract in the group of ICs. The first results concern the study population characteristics, including the most important confounding factors for cataract, as well as a detailed description of the work practices in interventional cardiology needed in order to reconstruct the cumulative eye lens dose. The data from 69 ICs and 23 controls collected based on the general medical questionnaire and the occupational questionnaire (for ICs only) were analyzed. The mean age of ICs and of the control group was 41 and 44, respectively, while the mean duration of work for exposed physicians was 9 years. The analysis of the data from the occupational questionnaire concerning the procedures performed, the use of various access routes, as well as radiation protection tools (eye lens glasses, ceiling suspended transparent shield, etc.) are also presented. On the basis of this information and additional assumptions about the doses per procedure (as well as reduction factors for various types of radiation measures), the cumulative doses to the eye lens of ICs were evaluated. They ranged up to 1.55 Sv and 0.4 Sv for left and right eye, respectively; however, the dose to only 3% of ICs exceeded the new threshold for development of eye lens opacities (0.5 Gy) proposed by the ICRP.

    This article focuses on organizational analysis in workplace health promotion (WHP) projects. It shows how this analysis can be designed such that it provides rational data relevant to the further context-specific and goal-oriented planning of WHP and equally supports individual and organizational change processes implied by WHP. Design principles for organizational analysis were developed on the basis of a narrative review of the guiding principles of WHP interventions and organizational change as well as the scientific principles of data collection. Further, the practical experience of WHP consultants who routinely conduct organizational analysis was considered. This resulted in a framework with data-oriented and change-oriented design principles, addressing the following elements of organizational analysis in WHP: planning the overall procedure, data content, data-collection methods and information processing. Overall, the data-oriented design principles aim to produce valid, reliable and representative data, whereas the change-oriented design principles aim to promote motivation, coherence and a capacity for self-analysis. We expect that the simultaneous consideration of data- and change-oriented design principles for organizational analysis will strongly support the WHP process. We finally illustrate the applicability of the design principles to health promotion within a WHP case study. PMID:21558286

    In order to improve the ground viability of missile weapon system, a quick orienting and aiming instrument is cried for the missile launching in modern war. The fiber optic gyroscope (FOG) based on Sagnac effect is a new type of all solid state rotation rate sensor that detects angular changes or angular rates relative to inertial space, which has many fine characteristics compared with traditional mechanical electronic gyro, such as low cost, light weight, long life, high reliability, wide dynamic range, etc. For the need of missile photoelectric aiming facility, It is necessary to design and manufacture a set of orienting and aiming instrument based on single axis FOG, to solve the close quarters aiming of missile launching, to measure the azimuth reference. Based on practical project, the principle of FOG orienting system and laser collimation theodolite aiming system is discussed and studied in this paper. Orienting and aiming system are constructed in the same basement. The influence of platform tilt on the precision of orientation is analyzed. An accelerator is used to compensate deviation caused by base tilt. The aiming precision affected by eccentricity of the encoders for laser collimation theodolite and the FOG orientation system are analyzed. The test results show that the aiming accuracy is 6' in three minutes. It is suitable for missile aiming in short range.

    It was shown that the blockage of epsilon-amino group of Lis-126 residue by 2,2,6,6-tetramethyl-4-oxo-piperidine-1-oxyl (TMPO) leads to the cooperative inactivation of glutamate dehydrogenase (L-glutamate-NAD(P)-oxidoreductase, EC 1.4.1.3). The data concerning cooperative inactivation of the enzyme are interpreted by the model of hexamer with identical orientation of subunits. It was shown that the modification of any of enzyme subunits is accompanied by an inactivation of the hexamer's fragment which is a dimer, with subunits interacting reciprocally by means of isological contacts.

    Tool review, namely the impression block, applied to check the shape and size of the top of fish as well as to determine the appropriate tool for fishing operation was realized. For multiple application and obtaining of the impress depth of 3 cm and more, the standard volumetric impression blocks with fix rods are used. However, the registered impress of fish is not oriented in space and the rods during fishing are in the extended position. This leads to rods deformation and sinking due to accidental impacts of impression block over the borehole irregularity and finally results in faulty detection of the top end of fishing object in hole. The impression blocks with copy rods and fixed magnetic needle allow estimating the object configuration and fix the position of magnetic needle determining the position of the top end of object in hole. However, the magnetic needle fixation is realized in staged and the rods are in extended position during fishing operations as well as it is in standard design. The most efficient tool is the impression block with copy rods which directs the examined object in the borehole during readings of magnetic needles data from azimuth plate and averaging of readings. This significantly increases the accuracy of fishing toll direction. The rods during fishing are located in the body and extended only when they reach the top of fishing object.

    The human visual system is highly adaptive to extract structure information for scene perception, and structure character is widely used in perception-oriented image processing works. However, the existing structure descriptors mainly describe the luminance contrast of a local region, but cannot effectively represent the spatial correlation of structure. In this paper, we introduce a novel structure descriptor according to the orientation selectivity mechanism in the primary visual cortex. Research on cognitive neuroscience indicate that the arrangement of excitatory and inhibitory cortex cells arise orientation selectivity in a local receptive field, within which the primary visual cortex performs visual information extraction for scene understanding. Inspired by the orientation selectivity mechanism, we compute the correlations among pixels in a local region based on the similarities of their preferred orientation. By imitating the arrangement of the excitatory/inhibitory cells, the correlations between a central pixel and its local neighbors are binarized, and the spatial correlation is represented with a set of binary values, which is named the orientation selectivity-based pattern. Then, taking both the gradient magnitude and the orientation selectivity-based pattern into account, a rotation invariant structure descriptor is introduced. The proposed structure descriptor is applied in texture classification and reduced reference image quality assessment, as two different application domains to verify its generality and robustness. Experimental results demonstrate that the orientation selectivity-based structure descriptor is robust to disturbance, and can effectively represent the structure degradation caused by different types of distortion.

    When the local area experienced tremendous growth and change, the radiology department at Maury Hospital in Columbia, Tennessee looked seriously at its orientation process in preparation for hiring additional personnel. It was an appropriate time for the department to review its orientation process and to develop a manual to serve as both a tool for supervisors and an ongoing reference for new employees. To gather information for the manual, supervisors were asked to identify information they considered vital for new employees to know concerning the daily operations of the department, its policies and procedures, the organizational structure of the hospital, and hospital and departmental computer systems. That information became the basis of the orientation manual, and provided an introduction to the hospital and radiology department; the structure of the organization; an overview of the radiology department; personnel information; operating procedures and computer systems; and various policies and procedures. With the manual complete, the radiology department concentrated on an orientation process that would meet the needs of supervisors who said they had trouble remembering the many details necessary to teach new employees. A pre-orientation checklist was developed, which contained the many details supervisors must handle between the time an employee is hired and arrives for work. The next step was the creation of a checklist for use by the supervisor during a new employee's first week on the job. A final step in the hospital's orientation program is to have each new employee evaluate the entire orientation process. That information is then used to update and revise the manual. PMID:10346648

    BACKGROUND: In Canada, more than 70% of new cases of hepatitis C virus (HCV) infection per year involve injection drug users (IDUs) and, currently, there is no consensus on how to offer them medical care. OBJECTIVE: To examine the characteristics of Canadian specialist physicians and their likelihood to provide treatment to HCV patients who are IDUs. METHODS: A nationwide, cross-sectional study was conducted in the specialty areas of hepatology, gastroenterology and infectious diseases to examine HCV services. The questionnaire requested information regarding basic demographics, referral pathways and opinions (yes/no), and examined how a physician’s treatment regimen is influenced by factors such as treatment eligibility, HCV care management and barriers to providing quality service. RESULTS: Despite the fact that the majority of prevalent and incident cases of HCV are associated with injection drug use, very few specialist physicians actually provide the necessary therapy to this population. Only 19 (19.79%) comprehensive service providers were likely to provide treatment to a current IDU who uses a needle exchange on a regular basis. The majority of comprehensive service providers (n=86 [89.58%]) were likely to provide treatment to a former IDU who was stable on substitution therapy. On bivariate analysis, factors associated with the likelihood to provide treatment to current IDUs included physicians’ type, ie, infectious disease specialists compared with noninfectious specialists (OR 3.27 [95% CI 1.11 to 9.63]), and the size of the community where they practice (OR 4.16 [95% CI 1.36 to 12.71] [population 500,000 or greater versus less than 500,000]). Results of the multivariate logistic regression analysis were largely consistent with the results observed in the bivariate analyses. After controlling for other confounding variables, only community size was significantly associated with providing treatment to current IDUs (OR 3.89 [95% CI 1.06 to 14

    Background Seafarers play an important role in the transmission of communicable diseases. The aim of the present study is to draw information and identify possible gaps on occupational health practices related to seafarers sailing on ships within the European Union Member States (EU MS) with focus on communicable diseases. Methods A structured questionnaire was sent to competent authorities from 21 EU MS. The questionnaire included questions about occupational health policies, medical certification of seafarers, communicable diseases reporting and relevant legislation. Descriptive analysis of the data was conducted by the use of Epi Info software: EU MS were categorized in four priority groups (A, B, C, D) based on: number of passenger ships visits, volume of passengers, and number of ports in each country. Moreover, EU MS were categorized to old and new, based on the date of entry in the EU. Results All 21 countries with relevant competent authorities responded to the questionnaire. The existence of specific national legislation/regulation/guidelines related to vaccination of seafarers was reported by three out of the 21 (14%) responding authorities. Surveillance data of communicable diseases related to seafarers are collected and analyzed by 4 (19%) authorities. Five out of 21 of the responding countries (24%) reported that tuberculin test result is required for the issuance of seafarer's medical certificate while a great variety of medical examination is required for the issuance of this certificate among countries. Gaps on occupational health services focused on communicable diseases related to maritime occupation have been reported by 33% of the responding countries. Responding authorities from Group A and B had the highest percentage of reported gaps followed by groups C and D. Old MS reported a higher frequency regarding gaps on occupational health services in comparison to new MS. Conclusion Our results revealed heterogeneity regarding occupational health

    Red meat, processed and unprocessed, has been considered a potential prostate cancer (PCA) risk factor; epidemiological evidence, however, is inconclusive. An association between meat intake and PCA may be due to potent chemical carcinogens that are generated when meats are cooked at high temperatures. We investigated the association between red meat and poultry intake and localized and advanced PCA taking into account cooking practices and polymorphisms in enzymes that metabolize carcinogens that accumulate in cooked meats. We analyzed data for 1096 controls, 717 localized and 1140 advanced cases from the California Collaborative Prostate Cancer Study, a multiethnic, population-based case–control study. We examined nutrient density-adjusted intake of red meat and poultry and tested for effect modification by 12 SNPs and 2 copy number variants in 10 carcinogen metabolism genes: GSTP1, PTGS2, CYP1A2, CYP2E1, EPHX1, CYP1B1, UGT1A6, NAT2, GSTM1 and GSTT1. We observed a positive association between risk of advanced PCA and high intake of red meat cooked at high temperatures (trend P = 0.026), cooked by pan-frying (trend P = 0.035), and cooked until well-done (trend P = 0.013). An inverse association was observed for baked poultry and advanced PCA risk (trend P = 0.023). A gene-by-diet interaction was observed between an SNP in the PTGS2 gene and the estimated levels of meat mutagens (interaction P = 0.008). Our results support a role for carcinogens that accumulate in meats cooked at high temperatures as potential PCA risk factors, and may support a role for heterocyclic amines (HCAs) in PCA etiology.

    Purpose: To determine what factors US radiation oncology residents consider when choosing academic or nonacademic careers. Methods and Materials: A 20-question online survey was developed and sent to all US radiation oncology residents to assess factors that influence their career interest. Residents were asked to rate their interest in academics (A) versus private practice (PP) on a 0 (strong interest in A) to 100 (strong interest in PP) scale. Responses were classified as A (0-30), undecided (40-60), and PP (70-100). Residents were also asked to rank 10 factors that most strongly influenced their career interest. Results: Three hundred thirty-one responses were collected, of which 264 were complete and form the basis for this analysis. Factors that correlated with interest in A included having a PhD (P=.018), postgraduate year level (P=.0006), research elective time (P=.0003), obtaining grant funding during residency (P=.012), and number of publications before residency (P=.0001), but not number of abstracts accepted in the past year (P=.65) or publications during residency (P=.67). The 3 most influential factors for residents interested in A were: (1) baseline interest before residency; (2) academic role models; and (3) research opportunities during residency. The 3 most influential factors for residents interested in PP were: (1) baseline interest before residency; (2) academic role models; and (3) academic pressure and obligations. Conclusions: Interest in A correlated with postgraduate year level, degree, and research time during residency. Publications before but not during residency correlated with academic interest, and baseline interest was the most influential factor. These data can be used by residency program directors to better understand what influences residents' career interest.

    This study examined adolescents' perceptions of parenting practices and extended kinship support in relation to academic adjustment for 104 African American and 60 European American 9th and 10th graders (14 and 15 year olds). For African-American teens, parental acceptance was associated with school values, teacher bonding, and work orientation. Higher levels of behavioral control and lower levels of psychological control were associated with a stronger work orientation. After accounting for the demographic variables and the three parenting practices, higher levels of extended kinship support related to stronger school values, higher teacher bonding, and a stronger work orientation. For European-American teens, parental acceptance related to academic adjustment, including stronger school values, higher teacher bonding, and a stronger work orientation. European-American adolescents with stronger extended kinship networks reported higher teacher bonding and a stronger work orientation. Results indicate the importance of extended kinship support for both African-American and European-American adolescents. PMID:16455133

    One of the biggest challenges for practitioners is implementing a new program or a new practice. This challenge is due, in large part, to a lack of information on strategies that promote effective and efficient program implementation. In most cases, implementation strategies have been limited to paper-based manuals that focus on describing…
