    Full Text Available Background. Team sports are not only the most exciting sporting events. but also complex activities that make serious demands on players. The effectiveness of the team depends not only on the high level of gaming interaction. but also on the relationship between the players. The work is based on the material of sports teams and is devoted to the study of the phenomenon of group cohesion. As a basic model. the authors choose a 4-factor model that describes cohesion in sports teams. The paper also considered the phenomenon of the emergence of the aggregate subject in the process of joint activity. when the participants feel themselves as a whole and experience feelings of satisfaction and a surge of energy. Objective. The main objective of the work is to investigate the relationship between the level of team cohesion and subjective feelings of unity of its players. As additional variables in the study there is a sport (football and volleyball and team level (amateur and professional. To test the assumptions. two methods were used (the Sport Team Cohesion Questionnaire and the Subject Unity Index. which allow not only to determine the overall level of cohesion and unity. but also to reveal the structure of both phenomena. The study involved two men’s volleyball and two men’s football teams of different ages: 8-9 years (39 athletes; 12-14 years (24 athletes and 18-25 years (41 athletes. Design. For amateur groups represented by children’s and teenage sports teams. significant correlations between unity and unity were obtained (r = 0.618. p <0.01; r = 0.477. p <0.05. For professional teams. no significant correlations were found. Influence of the sport on cohesion is also different for amateur and professional teams. In the first case. the cohesion is higher for football players (U = 118. p <0.05. and in the second case for volleyball players (U = 124. p <0.05. Results. The findings indicate that the professional level of players affects group

    2017-04-01

    Residual lactose and galactose in fermented dairy foods leads to several industrial and health concerns. There is very little information pertaining to manufacture of fermented dairy foods that are low in lactose and galactose. In the present study, comparative genomic survey demonstrated the constant presence of chromosome-encoded tagatose-6-phosphate (T6P) pathway in Lactobacillus casei group. Lactose/galactose utilization tests and β-galactosidase assay suggest that PTS Gal system, PTS Lac system and T6P pathway are major contributors for lactose/galactose catabolism in this group of organisms. In addition, it was found than lactose catabolism by Lb. casei group accumulated very limited galactose in the MRS-lactose medium and in reconstituted skim milk, whereas Streptococcus thermophilus and Lb. delbrueckii subsp. bulgaricus (Lb. bulgaricus) strains secreted high amount of galactose extracellularly. Moreover, co-culturing Lb. casei group with Str. thermophilus showed significant reduction in galactose content, while co-culturing Lb. casei group with Lb. bulgaricus showed significant reduction in lactose content but significant increase in galactose content in milk. Overall, the present study highlighted the potential of Lb. casei group for reducing galactose accumulation in fermented milks due to its species-specific T6P pathway. Copyright © 2016 Elsevier Ltd.

    Full Text Available Introduction: One of the ways of building and developing a better cooperative relationship between parents of people with severe and profound intellectual disabilities and professional staff is the inclusion of parents in support groups for parents and staff in support groups for staff. Goal: To examine the correlation of the level of cooperative relationship between the parents of people with severe and profound intellectual disabilities and professional staff with the inclusion of parents in support groups for parents and staff in support groups for staff. Methodology: Respondents: parents (296 of people with severe and profound learning disabilities and staff (298 in five centres across Slovenia; Methods: descriptive statistics, test of homogeneity, the rankit method, one-way analysis of variance; Procedures: survey questionnaires for parents and staff. The data was processed using SPSS software for personal computers. Results: The difference between the variances of the groups (parent found is statistically significant (F = 6.16; p = 0.01. Staff included in support groups have a significantly lower level of cooperative relationship with parents (f=10; M = - 0.12 than staff not included in these groups (f = 191; M = 0.04. Conclusion:In contrast to theoretical findings the results indicated less successful cooperation for professional staff included in support groups. The results furthermore did not confirm any differences in the cooperative relationship of parents included in support groups and those who are not. We suggest an in-depth analysis of the workings of support groups.

  8. Self-help groups for former patients: relations with mental health professionals.

    Emerick, R E

    1990-04-01

    Data from a national survey of 104 self-help groups for former mental patients were examined to assess actual and potential partnerships between these groups and mental health professionals. The groups' level of interaction with and attitudes toward professionals varied with the structure, affiliation, and service model of the groups. The majority were moderate "supportive" groups in which partnerships with professionals could occur but were problematic. Less common were radical "separatist" groups, with which professional partnerships were almost guaranteed to fail, and conservative "partnership" groups, with which partnerships were likely to succeed. Strong antipsychiatric attitudes throughout the mental patient movement suggest that mental health professionals who approach former-patient groups with narrow clinical conceptions of mental illness are likely to fail in establishing partnerships.

    2017-12-01

    In a help relation with a suicidal person, the theoretical models of suicidality can be essential to guide the health professional's comprehension of the client/patient. The objectives of this study were to identify health professionals' explanations of suicidal behaviors and to study the effects of professional group, theoretical intervention models, and patient suicide experience in professionals' representations. Two hundred and forty-two health professionals filled out a self-report questionnaire. Exploratory principal components analysis was used. Five explanatory models were identified: psychological suffering, affective cognitive, sociocommunicational, adverse life events, and psychopathological. Results indicated that the psychological suffering and psychopathological models were the most valued by the professionals, while the sociocommunicational was seen as the least likely to explain suicidal behavior. Differences between professional groups were found. We concluded that training and reflection on theoretical models in general and in communicative issues in particular are needed in the education of health professionals.

    To describe utilisation of health care services and motives for consultation in Primary Care in the native and the immigrant population, and compare this with the perception of primary care professionals. Data was collected on health care activity during the year 2006 for all people registered (N=86,966) in the 6 basic health care zones with the highest proportion of immigrants (14.4%) and on the following variables: country of origin, age, sex, year of inscription in the public health service. The health card and OMI-AP programme databases were used. A qualitative methodology of focus groups and in-depth interviews was employed. Seventy-two point four percent of immigrants requested care from the primary care professionals in 2006, of whom 50% proceeded from Ecuador and 70% were between 25 and 44 years old. Eighty-two percent of the natives made consultations and required more referrals to specialised care than the immigrants of the same age group. The most frequent consultation with natives and with immigrants was "acute respiratory infections" (7 to 23% according to age group). The second most frequent with immigrants was "administrative problems". The consultations with immigrants were not related to preventive aspects such as smoking and there were more consultations (p>0.001) for gynaeco-obstetric episodes (10.7%) and those related to work (19%) or psychosomatic problems (8.5%). The perception of the primary care professionals was that the immigrants carry out more consultations than the natives and generate a certain "disorder" in the clinic. Immigrants use healthcare services less than the native population. Nonetheless, this fact is not perceived in this way by the primary care professionals. Fewer preventive activities are carried out with immigrants, who suffer from more labour and psychosomatic problems.

    Full Text Available Objectives: Medical students and future physicians have chosen to pursue a profession that requires personal integrity, compassion and a constant awareness of the commitment made by them. Professionalism includes personal behaviors, knowledge, and competency. It includes the attitudes and values one holds and that run through the profession as a whole. Medical students learn professionalism during the course by either direct teaching or experiential learning. We conducted this study to estimate the self-reported level of practice of the core elements of professionalism by medical students and medical faculty and compared the two groups. Methods: One-hundred and nine students and 83 faculty members of Oman Medical College completed a professionalism questionnaire. The survey questions related to core elements of professionalism and were grouped under professional knowledge, professional skills, professional attitude, and qualities essential for professionalism. Results: The response rate was 65.6% (109 of 166 among students and 75.5% (83 of 110 from faculty members. Response to the questions on professional skills between the student and faculty group was significantly different (p < 0.001. Similarly, there was a significant difference in the responses related to professional attitude between the student and faculty group (p < 0.001.

    Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: The pursuit of perfection can cause anxiety and lead dancers to exceed their physical limits. The aim here was to evaluate the prevalence of pain symptoms and eating disorders among professional and amateur dancers. DESIGN AND SETTING: Observational cross-sectional study; Curitiba, PR, Brazil. METHODS: Data on 150 professional and non-professional practitioners of ballet, jazz and street dance were collected through specific questionnaires: Brief Pain Inventory-Short Form (BPI-SF, Eating Attitudes Test-26 (EAT-26, Bulimic Investigatory Test Edinburgh (BITE and State-Trait Anxiety Inventory-T-6 (STAI-T-6. RESULTS: Pain was observed in 58.6% of the sample, equally between professionals and amateurs (P = 0.19. Ballet dancers had more lower-limb pain than the other groups (P = 0.05. EAT-26 showed a tendency towards more eating disorders among the amateurs (P = 0.06. Higher risk of eating disorders was found among ballet dancers (P = 0.004 and jazz practitioners (P = 0.02 than among street dancers. Amateurs had more symptoms on the BITE scale (P < 0.0001, more pain (P = 0.002 and higher anxiety (P < 0.0001. Eating disorders were more common among females (P = 0.01 and singles (P = 0.02. Professionals were more satisfied with their own body image than amateurs (P < 0.001. CONCLUSIONS: Pain symptoms were found in almost half of the sample, equally among professionals and amateurs as well as between the three dance styles. Female and singles had more eating disorders. Those with eating disorders had higher levels of pain and anxiety.

    1996-10-01

    The outcome of clients who saw one of four "expert" professional group therapists selected by peer nomination or four "natural helper" nonprofessional nominated by students is contrasted in a 15-session psychotherapy group. Process measures tapping specific group and "common factors" were drawn from sessions 3, 8, and 14; outcome was assessed at pre, mid, posttreatment, and a 6-month follow-up. Results were examined by leader condition (professional vs. nonprofessional therapists) and time (group development). Virtually no reliable differences were found on measures of outcome primarily because of a floor effect on several measures. Therapist differences on the process measures tapping the "common factors" of therapeutic alliance, client expectancy, and perception of therapists were either nonsignificant or disappeared by the end of treatment. A complex picture of differences on one therapeutic factor (insight), common factor measures and subtle variation in the outcome data suggests a distinct pattern of change, however. Methodological limitations are also addressed including problems inherent in large-scale clinical-trial studies, ethical concerns raised by using nonprofessional leaders, and problems with generalizability, given the absence of significant psychopathology in group members.

    A germanosilicophosphate Ge 3P 6Si 2O 25 has been isolated. Its structure was solved from a single-crystal study in the space group P overline31c . Its cell parameters are a = b = 7.994(1) Å, c = 16.513(2) Å, Z = 2. The refinement by full-matrix least-squares calculations leads to R = 0.043 with 686 independent reflections. The structure of this oxide is built up from corner-sharing PO 4 and SiO 4 tetrahedra and GeO 6 octahedra. One observes a feature common to several silicophosphates: the presence of the structural unit P 6Si 2O 25 built up from a disilicate group sharing its corners with six PO 4 tetrahedra. The structural relationships between this oxide and the silicophosphates AMo 3P 6Si 2O 25 and Si 3P 6Si 2O 25 (or Ge 3P 6 Ge 2O 25) are described.

    Mental health professionals experiencing work-related stress may experience burn out, leading to a negative impact on their organization and patients. The aim of this study was to examine the effects of yoga classes on work-related stress, stress adaptation, and autonomic nerve activity among mental health professionals. A randomized controlled trial was used, which compared the outcomes between the experimental (e.g., yoga program) and the control groups (e.g., no yoga exercise) for 12 weeks. Work-related stress and stress adaptation were assessed before and after the program. Heart rate variability (HRV) was measured at baseline, midpoint through the weekly yoga classes (6 weeks), and postintervention (after 12 weeks of yoga classes). The results showed that the mental health professionals in the yoga group experienced a significant reduction in work-related stress (t = -6.225, p control group revealed no significant changes. Comparing the mean differences in pre- and posttest scores between yoga and control groups, we found the yoga group significantly decreased work-related stress (t = -3.216, p = .002), but there was no significant change in stress adaptation (p = .084). While controlling for the pretest scores of work-related stress, participants in yoga, but not the control group, revealed a significant increase in autonomic nerve activity at midpoint (6 weeks) test (t = -2.799, p = .007), and at posttest (12 weeks; t = -2.099, p = .040). Because mental health professionals experienced a reduction in work-related stress and an increase in autonomic nerve activity in a weekly yoga program for 12 weeks, clinicians, administrators, and educators should offer yoga classes as a strategy to help health professionals reduce their work-related stress and balance autonomic nerve activities. © 2015 The Authors.

    Full Text Available Wolter Paans, Inge Wijkamp, Egbert Wiltens, Marca V Wolfensberger Research and Innovation Group Talent Development in Higher Education and Society, Hanze University of Applied Sciences, Groningen, The Netherlands. Background: Determining what constitutes an excellent allied health care professional (AHCP is important, since this is what will guide the development of curricula for training future physical therapists, oral hygienists, speech therapists, diagnostic radiographers, and dietitians. This also determines the quality of care. Aim: To describe perspectives of AHCPs on which characteristics are commonly associated with an excellent AHCP. Methods: AHCPs' perspectives were derived from three focus group discussions. Twenty-one health care professionals participated. The final analysis of the focus group discussions produced eight domains, in which content validity was obtained through a Delphi panel survey of 27 contributing experts. Results: According to the survey, a combination of the following characteristics defines an excellent AHCP: (1 cognizance, to obtain and to apply knowledge in a broad multidisciplinary health care field; (2 cooperativity, to effectively work with others in a multidisciplinary context; (3 communicative, to communicate effectively at different levels in complex situations; (4 initiative, to initiate new ideas, to act proactively, and to follow them through; (5 innovative, to devise new ideas and to implement alternatives beyond current practices; (6 introspective, to self-examine and to reflect; (7 broad perspective, to capture the big picture; and (8 evidence-driven, to find and to use scientific evidence to guide one's decisions. Conclusion: The AHCPs perspectives can be used as a reference for personal improvement for supervisors and professionals in clinical practice and for educational purposes. These perspectives may serve as a guide against which talented students can evaluate themselves. Keywords: clinical

    Professional competence is important in delivering high quality patient care, and it can be enhanced by reflection and reflective discourse e.g. in mentoring groups. However, students are often reluctant though to engage in this discourse. A group mentoring program involving all preclinical students as well as faculty members and co-mentoring clinical students was initiated at Witten-Herdecke University. This study explores both the attitudes of those students towards such a program and factors that might hinder or enhance how students engage in reflective discourse. A qualitative design was applied using semi-structured focus group interviews with preclinical students and semi-structured individual interviews with mentors and co-mentors. The interview data were analyzed using thematic content analysis. Students' attitudes towards reflective discourse on professional challenges were diverse. Some students valued the new program and named positive outcomes regarding several features of professional development. Enriching experiences were described. Others expressed aversive attitudes. Three reasons for these were given: unclear goals and benefits, interpersonal problems within the groups hindering development and intrapersonal issues such as insecurity and traditional views of medical education. Participants mentioned several program setup factors that could enhance how students engage in such groups: explaining the program thoroughly, setting expectations and integrating the reflective discourse in a meaningful way into the curriculum, obliging participation without coercion, developing a sense of security, trust and interest in each other within the groups, randomizing group composition and facilitating group moderators as positive peer and faculty role models and as learning group members. A well-designed and empathetic setup of group mentoring programs can help raise openness towards engaging in meaningful reflective discourse. Reflection on and communication of

    A new IUGS Task Group entitled the Task Group on Global Geoscience Professionalism was formed in 2012 and launched at a symposium at the 341GC in Brisbane on strengthening communication between fundamental and applied geosciences and between geoscientists and public. The Task Group aims to ensure that the international geoscience community is engaged in a transformation of its profession so as to embed the need for a professional skills base alongside technical and scientific skills and expertise, within a sound ethical framework in all arenas of geoscience practice. This needs to be established during training and education and reinforced as CPD throughout a career in geoscience as part of ensuring public safety and effective communication of geoscience concepts to the public. The specific objective of the Task Group on Global Geoscience Professionalism that is relevant to this poster session is: • To facilitate a more 'joined up' geoscience community fostering better appreciation by academics and teachers of the professional skills that geoscientists need in the workplace, and facilitate better communication between academic and applied communities leading to more effective application of research findings and technology to applied practitioners and development of research programmes that truly address urgent issues. Other Task Group objectives are: • To provide a specific international forum for discussion of matters of common concern and interest among geoscientists and geoscientific organizations involved in professional affairs, at the local, national and international level; • To act as a resource to IUGS on professional affairs in the geosciences as they may influence and impact "Earth Science for the Global Community" in general - both now and in the future; • To offer and provide leadership and knowledge transfer services to countries and geoscientist communities around the world seeking to introduce systems of professional governance and self

    Let G be a nonabelian group of order p{sup 3}, where p is a prime number. Then G is a two generated group that its commutator, centre and Frattini subgroup coincide and are of order p. Hence, the quotient group of G over its centre and also Frattini quotient group of G, both are of order p{sup 2}. However, the first mentioned quotient is isomorphic to the inner group of G, which is a normal subgroup of automorphism group of G. Whereas, Frattini quotient group of G is an abelian elementary group that can be considered as a vector space of dimension two over Z{sub p}, the field of integers modulo p. In this paper, we consider to apply these properties of G to characterize the automorphism group of G.

    Professional identity formation in medical education is referenced increasingly as an object for educational reform. The authors introduce core concepts from two largely untapped literatures on identity and formation, contrasting framings on occupational preparation from within the organizational socialization literature with issues of socialization and professional acculturation from a military sciences perspective.The organizational sciences literature emphasizes socializing a workforce to "fit in," raising questions about how organization values might clash with core professional values concerning patient primary and social justice. The military literature, in turn, advances the notions of professional identity as a collective property, and that a particular social other (the public) must participate in shaping the group's identity as a profession.The authors extrapolate from these reviews that the training of physicians-as-professionals, and thus issues of socialization and identity formation, require intentionality and specificity around these contrasting issues. In turn, they argue that medical educators must attend to socializing trainees to a professional group identity while at the same time producing health care professionals who retain the capacity to resist the bureaucratic application of standardized solutions to contemporary problems. Educators must thus strive to identify the skills, knowledge, and attitudes necessary that will allow physicians-qua-professionals to function as a quasi-subversive work force and to disrupt the very system that helped to shape their identity, so that they may fulfill their mission to their patients.

    Full Text Available The present work aims to present the conceptual characteristics about collaborative groups and to identify their importance in the professional development process of teachers who teach Mathematics. For this, we adopt a methodology of bibliographic research in which we bring authors who discuss this theme. Our theoretical framework is supported by authors who discuss the importance of collaborative groups in the teaching of Mathematics. The results show that the collaborative groups contribute to the professional development of teachers by promoting, through reflexivity, spaces of collective discussions about the practice of teachers in the classroom.

    The MPOWER strategy encourages suitable monitoring of the tobacco epidemic among health professionals in all countries. To analyse the prevalence of and attitudes towards tobacco use among Spanish health professionals. A study was conducted based on an online survey. The study population consisted of health professionals (primary care physicians, specialist physicians and nurses). The questionnaire used included questions about tobacco consumption, knowledge of and attitudes towards smoking. The sample size was calculated according to a database with 9,500 e-mail addresses and listings of health centres and hospitals all over Spain. Statistical analysis was done using the SPSS software programme. The study group comprised a total of 612 health professionals: 322 were women (52.6%), 196 were nurses and 416 were physicians. 11.7% of health professionals were smokers (9.6% regular smokers and 2.1% occasional smokers) and 41.3% were ex-smokers. Within the group of daily smokers, differences were observed between the nurses and the physicians: 11.2 versus 8.9% (p = 0.009). Smoking was recognized as a chronic disorder by 58.2% of health professionals, and 54.6% knew that the most effective intervention to help quit is a combination of psychological and pharmacological treatment. 56% of health professionals always asked their patients about their tobacco consumption. 11.7% of Spanish health professionals are smokers. We found that they have low knowledge about strategies to quit smoking and that there is a low level of therapeutic intervention on smokers. © 2015 S. Karger AG, Basel.

    A scientific career is often more than a 9-to-5 commitment, both in terms of time and passion. An important factor that fuels this passion is engaging with the community on many levels. In the history of education and professional development, there are numerous studies that emphasis the importance of surrounding groups and like-minded peers in one's professional and personal development in a less constrained environment. In our experience, in modern days where students are surrounded with too much information and yet too little clear signal, the idea of mentor and advisor can no longer limit to one or two people. We strongly feel it is imperative to have the opportunity to share expertise on scientific issues, career options, develop presenting and writing skills, participate in professional volunteer activities with alike and advanced colleagues, share future opportunities, and successfully navigating life both inside and outside of graduate school in a relaxed environment. Most of the professional scientific and engineering communities put a lot of effort to create and maintain professional groups in masters and Ph.D. levels but the dynamics within these groups prove it to be very different and it is challenging to maintain both momentum and productivity. Authors of this report would present their experience in creating, running and maintaining various student groups in the discipline of physics, astronomy, planetary science, hydrology, and optical engineering in US, Europe and Middle East. The common factors and differences based on the supportive community, location, and the educational level would be discussed. An outline of potential helpful factors within the academic institutes and professional communities would be presented based on the examination on various successful and unsuccessful experiences.

    2007-02-01

    Because the effectiveness of self-help groups (SHGs) has not been proven yet and also since multi-focus reviews on SHGs are rare, the present article offers an overview of the current state of research. Possible reasons for the conflicting results in the literature are also investigated. An extensive literature search was done to review studies which used longitudinal design and control groups to measure the effectiveness of SHGs and so-called "support groups". Positive effects in comparison to the control groups were proven in four out of seven of the studies. In the remaining three studies the outcomes between the groups were the same. Considering the naturalistic designs of the studies, these results clearly indicate that SHGs are indeed effective. An insufficient consideration of the heterogeneity of the groups is held responsible for the difficulties associated with previous research on the topic, especially as far as the differentiation between SHGs and professionally led groups is concerned. The definition excludes professional leadership but, in fact, professional involvement in SHGs up to their leadership is the rule. The following suggestions have been derived from this literature analysis: uniform classifications for SHGs and professionally-led support groups should be established in order to make it possible to provide a clear distinction between these types of groups as well as to indicate the extent of professional involvement in them. A plea is made for a generally stronger consideration of organisational differences in the research of SHGs.

    The modern primary healthcare workforce needs to be resilient. Early research framed professional resilience as avoiding 'burnout'; however, more recent literature has introduced the concept of positive adaptation to professional challenges, which results in individuals thriving in their role. To explore what primary health professionals working in challenging environments consider to be characteristics of resilience and what promotes or challenges professional resilience. A qualitative focus group in north east Scotland. Five focus groups were held with 20 health professionals (six GPs, nine nurses, four pharmacists, and a practice manager) based in rural or deprived city areas in the north east of Scotland. Inductive thematic analysis identified emerging themes. Personal resilience characteristics identified were optimism, flexibility and adaptability, initiative, tolerance, organisational skills, being a team worker, keeping within professional boundaries, assertiveness, humour, and a sense of self-worth. Workplace challenges were workload, information overload, time pressures, poor communication, challenging patients, and environmental factors (rural location). Promoters of professional resilience were strong management support, teamwork, workplace buffers, and social factors such as friends, family, and leisure activities. A model of health professional resilience is proposed that concurs with existing literature but adds the concept of personal traits being synergistic with workplace features and social networks. These facilitate adaptability and enable individual health professionals to cope with adversity that is inevitably part of the everyday experience of those working in challenging healthcare environments. © British Journal of General Practice 2016.

    Although professional models are thought to be a high-risk group for body image concerns, only a handful of studies have empirically investigated this possibility. The present study sought to overcome this dearth of information by comparing professional models and a matched sample on key indices of body image and appeared-related concerns. A group of 52 professional fashion models was compared with a matched sample of 51 non-models from London, England, on indices of weight discrepancy, body appreciation, social physique anxiety, body dissatisfaction, drive for thinness, internalization of sociocultural messages about appearance, and dysfunctional investment in appearance. Results indicated that professional models only evidenced significantly higher drive for thinness and dysfunctional investment in appearance than the control group. Greater duration of engagement as a professional model was associated with more positive body appreciation but also greater drive for thinness. These results indicate that models, who are already underweight, have a strong desire to maintain their low body mass or become thinner. Taken together, the present results suggest that interventions aimed at promoting healthy body image among fashion models may require different strategies than those aimed at the general population.

    Full Text Available Abstract Background There is worldwide variation in rehabilitation practices after total hip arthroplasty (THA and total knee arthroplasty (TKA and no agreement on which interventions will lead to optimal short and long term patient outcomes. As a first step in the development of clinical practice guidelines for post-acute rehabilitation after THA and TKA, we explored experiences and attitudes about rehabilitation practices and outcomes in groups of individuals identified as key stakeholders. Methods Separate focus groups and interviews were conducted with patients (THA or TKA within past year and three health professional groups: allied health professionals (AHPs, orthopaedic surgeons, and other physicians, in Canada and the United States. Pairs of moderators led the focus groups using a standardized discussion guide. Discussions were audiotaped and transcribed verbatim. A content analysis within and across groups identified key themes. Results Eleven focus groups and eight interviews took place in six sites. Patients (n = 32 varied in age, stage of recovery, and surgical and rehabilitation experiences. Health professionals (n = 44 represented a range of disciplines, practice settings and years of experience. Six key themes emerged: 1 Let's talk (issues related to patient-health professional and inter-professional communication; 2 Expecting the unexpected (observations about unanticipated recovery experiences; 3 It's attitude that counts (the importance of the patient's positive attitude and participation in recovery; 4 It takes all kinds of support (along the continuum of care; 5 Barriers to recovery (at patient, provider and system levels, and 6 Back to normal (reflecting diversity of expected outcomes. Patients offered different, but overlapping views compared to health professionals regarding rehabilitation practices and outcomes following THA and TKA. Conclusion Results will inform subsequent phases of guideline development and ensure

    The objective of this study is to evaluate longitudinal change in plasma neurofilament light (NF-L) and tau levels in relationship to clinical and radiological measures in professional fighters. Participants (active and retired professional fighters and control group) underwent annual blood sampling, 3 Tesla MRI brain imaging, computerized cognitive testing, and assessment of exposure to head trauma. Plasma tau and NF-L concentrations were measured using Simoa assays. Multiple linear regression models were used to compare the difference across groups in regard to baseline measurements, while mixed linear models was used for the longitudinal data with multiple measurements for each participant. Plasma samples were available on 471 participants. Baseline NF-L measures differed across groups (F_3,393=6.99, p=0.0001), with the active boxers having the highest levels. Higher NF-L levels at baseline were correlated with lower baseline MRI regional volumes and lower cognitive scores. The number of sparring rounds completed by the active fighters was correlated with NF-L (95% CI 0.0116-0.4053, p=0.0381), but not tau, levels. Among 126 subjects having multiple yearly samples, there was a significant difference in average yearly percentage change in tau across groups (F_3,83=3.87, p=0.0121).). We conclude that plasma NF-L and tau behave differently in a group of active and retired fighters; NF-L better reflects acute exposure whereas the role of plasma tau levels in signifying chronic change in brain structure over time requires further study.

    Full Text Available Noise influence takes one of the leading roles in the development of sensorineural hearing loss (SHL. At the same time professional deafness steadily occupies the 5th place in the structure of occupational diseases in Ukraine over the past few years. Of special importance is the problem of pre-clinical and early diagnosis of occupational hearing deterioration, in sense of timely prophylactic and rehabilitation measures in “risk group” workers. The objective research methods play an important role in the diagnosis of auditory analyzer state. Many scientific studies have shown the diagnostic effectiveness of method of otoacoustic emissions recording in the early diagnosis of lesions of receptor part of auditory analyzer. It is known that SHL of noise genesis largely affects the receptor part of the auditory analyzer, for which the OAE method has great practical diagnostic significance. Objective: to study informativity indicators of otoacoustic emission for the diagnosis of sensorineural hearing loss in various occupational groups of coal workers in Ukrainian mines. Materials and Methods: Auditory function of 87 workers of the coal industry (drifters, miners and longwall miners with different levels of industrial noise and hygienic conditions in their workplaces was: 28 studied drifters (group 1, 25 miners (group 2 and 34 longwall miners (group 3. Work experience in noise in these groups was 17,9±1,0; 23,1±1,0 and 22,2±2,0 accordingly. Noise ratio in drifters was 93,6±4,9 dBA, in miners – 92,9±5,5 dBA and in longwall miners – 86,5±6,04 dBA accordingly, while the maximum permitted level is 80 dBA.

    Healthcare professionals' person-centered communication skills are pivotal for successful group-based diabetes education. However, healthcare professionals are often insufficiently equipped to facilitate person-centeredness and many have never received post-graduate training. Currently, assessing professionals' skills in conducting group-based, person-centered diabetes education primarily focus on experts measuring and coding skills on various scales. However, learner-centered approaches such as adequate self-reflective tools have been shown to emphasize professional autonomy and promote engagement. The aim of this study was to explore the potential of a self-assessment tool to identify healthcare professionals' strengths and areas in need of professional development to aid effective facilitation of group-based, person-centered diabetes education. The study entails of two components: 1) Field observations of five different educational settings including 49 persons with diabetes and 13 healthcare professionals, followed by interviews with 5 healthcare professionals and 28 persons with type 2 diabetes. 2) One professional development workshop involving 14 healthcare professionals. Healthcare professionals were asked to assess their person-centered communication skills using a self-assessment tool based on challenges and skills related to four educator roles: Embracer, Facilitator, Translator, and Initiator. Data were analyzed by hermeneutic analysis. Theories derived from theoretical model 'The Health Education Juggler' and techniques from 'Motivational Interviewing in Groups' were used as a framework to analyze data. Subsequently, the analysis from the field notes and interview transcript were compared with healthcare professionals' self-assessments of strengths and areas in need to effectively facilitate group-based, person-centered diabetes education. Healthcare professionals self-assessed the Translator and the Embracer to be the two most skilled roles whereas

    In primary health care, efficacious treatment strategies are lacking for these patients, although the most prominent symptoms accounting for consultation in primary care often cannot be related to any biological causes. The aim was to explore whether group supervision from a specific phenomenological theory of psychosomatics could provide healthcare professionals treating patients with psychosomatic health issues within primary care a deeper understanding of these conditions and stimulate profession-specific treatment strategies. Our research questions were as follows: (i) What is the healthcare professionals' understanding of psychosomatics before and after the intervention? (ii) What are the treatment strategies for this group of patients before and after the intervention? The study was an explorative qualitative intervention pilot study. The six participants from a primary healthcare setting in a medium-sized city in Sweden participated in the study. A supervision group was formed, based on a mix of professions, age, gender and years of clinical experience. Supervision consisted of one 75-minutes meeting every month during the course of 6 months. Participants were interviewed before and after the supervision intervention. The study showed two distinct categories emerged from the data. One category of healthcare professionals espoused a psycho-educative approach, while the other lacked a cohesive approach. The supervision improved the second category of healthcare professionals' understanding of psychosomatics. The psycho-educative group did not change their understanding of psychosomatics, although they felt strengthened in their approach by the supervision. Profession-specific strategies were not developed. This pilot study indicates that a relatively short supervision intervention can aid clinicians in their clinical encounters with these patients; however, further research is necessary to ascertain the value of the specific phenomenologically based

    This work was devoted to nucleon induced transfer reactions having the potential to probe the sub-cluster structures of the benchmark halo nucleus He 6, without the question marks the necessarily omitted exchange effects tend to put behind the CRC results when both collision partners are composite systems. Still, the exchange complications entered the analysis in an ironic way: The high Q-value of the p(He 6,α)t and p(He 6, t)α reactions caused sensitivity to the t - α optical potential at small radii, where the one-nucleon exchange effects are strongest. Since the attempt to throw them out of the extracted tau - α potential failed, it was necessary to extend the model space to avoid a too difficult modelling of the local equivalent t - α potential. By this step, all the complications originating from antisymmetrization within a larger model space entered the analysis. However, the persistent failures of the two-channel calculations of this and previous works can hardly be due to incorrect treatment of exchange effects only, so the loss of simplicity is probably illusory. Even at small angles, where the surface processes dominate, none of the two-channel calculations with various choices of t - α optical potentials managed to reproduce the p(He 6, α)t (p(He 6,t)α) data. This motivated inclusion of sequential transfers through the d + He 5 channel, where the sequential triton transfer process, included just for consistency in the coupling scheme of the four-channel calculation, turned out to be more influent than expected. The satisfactory reproduction of both the p(He 6, He 5)d and the p(He 6,α)t (p(He 6,t)α) data by the four-channel approach and the required re-normalization the real part of the p - He 6 optical potential are strong indications of substantial contributions from sequential transfer of the halo neutrons at this energy. The conclusions that can be drawn from this work are limited by the modest amount of available data. This limitation does

The satisfactory reproduction of both the p(He 6, He 5)d and the p(He 6,{alpha})t (p(He 6,t){alpha}) data by the four-channel approach and the required re-normalization the real part of the p - He 6 optical potential are strong indications of substantial contributions from sequential transfer of the halo neutrons at this energy. The conclusions that can be drawn from this work are limited by the

    The ever-evolving nature of nursing requires professionals to keep their knowledge up to date and uphold the Nursing and Midwifery Council (NMC) Code by engaging themselves in ongoing personal and professional development (PPD). This article aims to highlight the importance of good leadership and management in healthcare and to explore the literature surrounding leadership and management, such as the current NHS healthcare leadership model ( NHS Leadership Academy 2013 ), the Leading Change, Adding Value Framework underpinned by the 10 commitments and 6Cs ( NHS England 2016 ) and the NMC Code ( NMC 2015a ) in relation to PPD. It examines how nurses can be supported in their PPD by their team leader and or managers using examples experienced in a clinical setting while caring for children and young people (CYP). Furthermore, the importance of team working and group processes in the context of leadership will be deliberated, using examples of formative group work to illustrate principles described in the literature. Finally, reflections will be discussed on how learning from this experience can influence future practice when caring for CYP. ©2018 RCN Publishing Company Ltd. All rights reserved.

    Zhao Xingli; Zhao Conghai; Tian Yu

    2002-01-01

    Objective: T observe the change of expression of p16 gene product, P16 protein, after treated by gamma knife on glioma cell line C6. Methods: Glioma C6 cells proliferated in vitro, treated by γ-knife in dose of 5.00 and 6.22 Gy, respectively. P16 protein was detected by immunohistochemical technique and image analysis. Results: The P16 protein in glioma C6 cells was notably increased after treatment with γ knife (P < 0.01). The grey number in C6 group (control group) was 167.1 +- 6.2 and was 155.4 +- 2.0 and 124.9 +- 7.1, respectively, in 5.00 Gy and 6.22 Gy gamma knife treated group. Conclusion: It is suggests that one of the mechanisms of glioma cell C6 apoptosis induced by γ-knife radiation may be associated with activation of p16 gene and increase of P16 protein expression

    In spite of the high rate of overuse injuries in ballet dancers, no studies have investigated the prevalence of overuse injuries in professional dancers by providing specific diagnoses and details on the differences in the injuries sustained as a function of age and/or years of professional practice. Overuse injuries are the most prevalent injuries in ballet dancers. Professional ballet dancers suffer different types of injuries depending on their age and years of professional practice. Descriptive epidemiology study. This descriptive epidemiological study was carried out between January 1, 2005, and October 10, 2010, regarding injuries sustained by professional dancers belonging to the major Spanish ballet companies practicing classical, neoclassical, contemporary, and Spanish dance. The sample was distributed into 3 different groups according to age and years of professional practice. Data were obtained from the specialized medical care the dancers received from the Trauma and Orthopaedic Surgery Service at Fremap in Madrid. The dependent variable was the study of the injury. A total of 486 injuries were identified over the study period, with overuse injuries being the most common etiology ( P ballet and veteran dancers practicing contemporary ballet ( P = .01). Specifically, among other findings, stress fractures of the base of the second metatarsal ( P = .03), patellofemoral syndrome, and os trigonum syndrome were more prevalent among junior professionals ( P = .04); chondral injury of the knee in senior professionals ( P = .04); and cervical disc disease in dancers of intermediate age and level of experience. Overall, overuse injuries were more prevalent in younger professionals, especially in women. This finding was especially true for the more technical ballet disciplines. On the other hand, in the athletic ballet disciplines, overuse lesions occurred mainly in the more senior professionals. This study provides specific clinical diagnoses obtained through

    Glomerular filtration rate (GFR) has been shown to be lower than physiological values during exercise with a strong negative correlation with exercise intensity. Among new markers of renal function, neutrophil gelatinase-associated lipocalin (NGAL) seems to be very promising. It is an early, sensitive and specific marker of acute kidney injury (AKI) with two isoforms: plasma NGAL (pNGAL) and urinary NGAL (uNGAL). The aim of the present study was to assess acute variations in NGAL plasma levels after performing high endurance physical exercise in a group of professional cyclists during the two major European professional cycling competitions (Giro D’Italia and Tour de France). Eighteen professional cyclistis were recruited for the study. A blood sample was collected during rest (after 8 hours fasting) and immediately after the competition (mountain stages) in order to assess the effect of very intense exercise on kidney function by measuring the variations of pNGAL. We also assessed plasma levels of creatinine, creatine-kinase (CK), LDH, transaminases and electrolytes. The results showed that Creatinine, CK and electrolytes levels remained almost stable between rest and post-competition. The levels of transaminases and NGAL showed a mild increase between rest and post-competition, with a significant difference between the two values only for transaminases (p=0.005). However, post-competition values of all investigated variables remained within the physiological range. The results of the present study suggest that even if NGAL values mildly rose after competition, no kidney injury occurred in these highly trained athletes during mountain stages of professional competitions. Other studies in literature confirmed that high endurance physical exercise seems not to cause renal injury in elite athletes. This is probably due to adaptive mechanisms of renal function and to the adaptation to physical stress gained with training.

    The authors previously reported that cells under chronic low pH (6.6) conditions have altered thermotolerance. They further characterized both the doubling time (t/sub d/) and the internal pH (pH/sub 1/) of CHO cells continuously cultured at pH 6.6 for times greater than one year. The following differences were noted: 1) A t/sub d/ of 16 hr compared to a t/sub d/ of 12 hr for cells at normal pH (7.3) and a t/sub d/ of 25 hr for the acute low pH cells (pH = 6.6; incubation time = 4 hr). 2) A pH/sub i/ 0.1-0.15 pH units > normal cells and 0.3 pH units > acute low pH cells. 3) Survival at 42.0 0 C which differed from both normal and acute low pH cells. The chronic culture was still quite sensitive to 42.0 0 C treatments during the first 5 hr, but developed tolerance at a higher level than cells under acute low pH conditions. The pH/sub i/ of the chronic culture responded to 42.0 0 C heating in a manner similar to that for acute low pH cells. Whether this culture represents a normal response to long term low pH exposure, or was the response of a mutant population is at the present unknown

    Professionals within the mental health services face many ethical dilemmas and challenging situations regarding the use of coercion. The purpose of this study was to evaluate the significance of participating in systematic ethics reflection groups focusing on ethical challenges related to coercion. In 2013 and 2014, 20 focus group interviews with 127 participants were conducted. The interviews were tape recorded and transcribed verbatim. The analysis is inspired by the concept of 'bricolage' which means our approach was inductive. Most participants report positive experiences with participating in ethics reflection groups: A systematic and well-structured approach to discuss ethical challenges, increased consciousness of formal and informal coercion, a possibility to challenge problematic concepts, attitudes and practices, improved professional competence and confidence, greater trust within the team, more constructive disagreement and room for internal critique, less judgmental reactions and more reasoned approaches, and identification of potential for improvement and alternative courses of action. On several wards, the participation of psychiatrists and psychologists in the reflection groups was missing. The impact of the perceived lack of safety in reflection groups should not be underestimated. Sometimes the method for ethics reflection was utilised in a rigid way. Direct involvement of patients and family was missing. This focus group study indicates the potential of ethics reflection groups to create a moral space in the workplace that promotes critical, reflective and collaborative moral deliberations. Future research, with other designs and methodologies, is needed to further investigate the impact of ethics reflection groups on improving health care practices.

    Teaching professionalism effectively to fully engaged residents is a significant challenge. A key question is whether the integration of professionalism into residency education leads to a change in resident culture. The goal of this study was to assess whether professionalism has taken root in the surgical resident culture 3 years after implementing our professionalism curriculum. Evidence was derived from 3 studies: (1) annual self-assessments of the residents' perceived professionalism abilities to perform 20 defined tasks representing core Accrediting Council on Graduate Medical Education professionalism domains, (2) objective metrics of their demonstrated professionalism skills as rated by standardized patients annually using the objective structure clinical examination tool, and (3) a national survey of the Surgical Professionalism and Interpersonal Communications Education Study Group. Study 1: aggregate perceived professionalism among surgical residents shows a statistically significant positive trend over time (P = .016). Improvements were seen in all 6 domains: accountability, ethics, altruism, excellence, patient sensitivity, and respect. Study 2: the cohort of residents followed up over 3 years showed a marked improvement in their professionalism skills as rated by standardized patients using the objective structure clinical examination tool. Study 3: 41 members of the national Surgical Professionalism and Interpersonal Communications Education Study Group rated their residents' skills in admitting mistakes, delivering bad news, communication, interdisciplinary respect, cultural competence, and handling stress. Twenty-nine of the 41 responses rated their residents as "slightly better" or "much better" compared with 5 years ago (P = .001). Thirty-four of the 41 programs characterized their department's leadership view toward professionalism as "much better" compared with 5 years ago. All 3 assessment methods suggest that residents feel increasingly

    Full Text Available OBJECTIVES: Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS: A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B. Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post- were analyzed by two pediatric pulmonologists. RESULTS: Of the 66 professionals, 87.9% were females. Of a total possible score of ten, the mean score obtained in the pre-test was 5.3 ± 3, and in the second test, 7.5 ± 2 (p < 0.000. There were no significant differences when comparing the two groups (p = 0.726. The nurses had the lowest mean scores in the initial test (2.3 ± 2; however, they were the group that learned the most with the intervention, showing similar means to those of other groups in the second test (6.1 ± 3. CONCLUSION: There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods, demonstrating that education, when available to professionals, positively modifies medical practice.

    Full Text Available OBJECTIVE: To assess the impact of multiple sclerosis (MS on the professional life of Brazilian patients. METHOD: One hundred MS patients were randomly selected from the database of the Brazilian Multiple Sclerosis Association (ABEM. An individual interview was carried out by telephone by a member of ABEM, who collected data on the patients' clinical status, educational level and professional lives. RESULTS: Complete data were obtained from 96 patients (27 males and 69 females aged 55.0±14.1 years, with average disease duration of 4.6±4.0 years. Eighty percent had eleven or more years of schooling. Among the whole group, 66% did not present limitations on walking. The longer the disease duration and the older the patient were, the higher the chances were that the patient was retired or receiving workers' compensation benefits. However, even among patients with MS for less than five years, the rate of non-participation in the workforce was 47.7%. Fatigue, paresthesia, cognitive dysfunction and pain were often cited as the motives for not working. CONCLUSION: MS patients presented high levels of unemployment, retirement and receipt of workers' compensation benefits, despite their high schooling levels. Age, disease duration and disability influenced these results for the whole group. However, even among younger patients with shorter disease duration and low disability, this finding remained.

    The HEPiX (http://www.hepix.org) IPv6 Working Group has been investigating the many issues which feed into the decision on the timetable for the use of IPv6 (http://www.ietf.org/rfc/rfc2460.txt) networking protocols in High Energy Physics (HEP) Computing, in particular in the Worldwide Large Hadron Collider (LHC) Computing Grid (WLCG). RIPE NCC, the European Regional Internet Registry (RIR), ran out ofIPv4 addresses in September 2012. The North and South America RIRs are expected to run out soon. In recent months it has become more clear that some WLCG sites, including CERN, are running short of IPv4 address space, now without the possibility of applying for more. This has increased the urgency for the switch-on of dual-stack IPv4/IPv6 on all outward facing WLCG services to allow for the eventual support of IPv6-only clients. The activities of the group include the analysis and testing of the readiness for IPv6 and the performance of many required components, including the applications, middleware, management and monitoring tools essential for HEP computing. Many WLCG Tier 1/2 sites are participants in the group's distributed IPv6 testbed and the major LHC experiment collaborations are engaged in the testing. We are constructing a group web/wiki which will contain useful information on the IPv6 readiness of the various software components and a knowledge base (http://hepix-ipv6.web.cern.ch/knowledge-base). This paper describes the work done by the working group and its future plans.

    2016-03-01

    Full Text Available Acute whole body vibration (WBV is an increasingly popular training technique amongst athletes immediately prior to performance and during scheduled breaks in play. Despite its growing popularity, evidence to demonstrate its effectiveness on acute neuromuscular responses is unclear, and suggestions that athlete ability impacts effectiveness warrant further investigation. The purpose of this study was to compare the neuromuscular effects of acute WBV and perceptions of whether WBV is an effective intervention between amateur and professional soccer players. Participants were 44 male soccer players (22 professional and 22 amateur; age: 23.1 ± 3.7 years, body mass: 75.6 ± 8.8 kg and height: 1.77 ± 0.05 m. Participants in each group were randomly assigned to either an intervention of 3 x 60 s of WBV at 40 Hz (8mm peak-to-peak displacement or control group. Peak knee isometric force, muscle activation and post activation potentiation (PAP of the knee extensors along with self-report questionnaire of the perceived benefits of using the intervention were collected. A three-way ANOVA with repeated measures revealed professional players demonstrated a significant 10.6% increase (p < 0.01, Partial Eta2 = 0.22 in peak knee isometric force following acute WBV with no significant differences among amateur players. A significant difference (p < 0.01, Partial Eta2 = 0.16 in PAP amongst professional players following acute WBVT was also reported. No significant differences amongst amateur players were reported across measurements. Results also indicated professional players reported significantly stronger positive beliefs in the effectiveness of the WBV intervention (p < 0.01, Partial Eta2 = 0.27 compared to amateur players. Acute WBV elicited a positive neuromuscular response amongst professional players identified by PAP and improvements in knee isometric peak force as well as perceived benefits of the intervention, benefits not found among amateur players.

    2006-01-01

    Building on the respective strengths of parent-led and professional-led groups, a parent-professional team leadership model for group interventions was developed and evaluated for families of youths with emotional and behavioral problems. The model was developed based on feedback from 26 parents in focus group sessions and recommendations from mental health professionals in staff meetings. Evaluations of an implementation of the model in a support, empowerment, and education group intervention (S.E.E. group) have demonstrated the usefulness of this approach in work with families of children with behavioral and emotional problems. This article discusses the challenges of instituting the model in an S.E.E. group. It explores how parents and professionals build the team leadership model and the strengths of this approach in working with parents of youths with serious emotional disturbances.

    The sixth spectrum of barium (Ba VI) has been investigated with the aid of experimental recordings made on a 3-m normal incidence vacuum spectrograph of Antigonish laboratory (Canada) in the wavelength region 300–2080 Å using triggered spark as an excitation source. The spectral analysis has been extended considerably to include new configuration the 5s 2 5p 2 6p in odd parity matrix and the 5s 2 5p 2 6d and 5s 2 5p 2 7s configurations in even parity matrix. Previously reported levels of the ground configuration (5s 2 5p 3 ) and three lowest excited configurations the 5s5p 4 , 5s 2 5p 2 5d and 5s 2 5p 2 6s have been confirmed and the two unknown levels of the 5s 2 5p 2 5d configuration with J=9/2, have now been established through the identification of transitions from the 5s 2 5p 2 6p levels. All twenty one levels of the 5s 2 5p 2 6p configuration and twenty nine levels out of thirty six of the 5s 2 5p 2 6d and 5s 2 5p 2 7s configurations have now been established. Hartree–Fock calculations involving configuration interactions support the analyses. The accuracy of our wavelength measurement is ±0.005 Å for sharp lines. - Highlights: • The spectrum of Ba was recorded on a 3-m spectrograph with triggered spark source. • Atomic transitions for Ba VI were identified to established new energy levels. • CI calculations with relativistic corrections were made for theoretical predictions. • Weighted oscillator strength (gf) and transition probabilities (gA) were calculated

  11. Health professionals perceive teamwork with relatives as an obstacle in their daily work - a focus group interview.

    Laursen, Jannie; Broholm, Malene; Rosenberg, Jacob

    2017-09-01

    Health professionals must often balance between different rationalities within the hospital organisation. Having adequate time with patients, shorter waiting time and the ability to greater professional autonomy have been shown to help provide a higher quality of care. Empathy and sympathy appear to be crucial components for the health professionals and their relationship to patients. The aim of this study was to explore health professionals' experiences of relatives to critically ill patients in order to identify aspects that may facilitate a better understanding of this teamwork. The study was descriptive and exploratory and had a qualitative design with a phenomenological/hermeneutic orientation for the interviews. Focus group was the chosen methodology. The study comprised 19 health professionals in four focus groups. Two themes emerged from the interviews: the hospital culture does not integrate relatives, and health professionals felt that relatives took their resources and saw them as an obstacle in their daily work. Health professionals felt divided between the system and the individual sphere, which makes it difficult for them to integrate relatives more and see them as participants in a natural teamwork for the benefit of the patient. © 2016 Nordic College of Caring Science.

    To examine the dietary habits of professional soccer players at two Scottish Premier League clubs during the competitive season. A study of the dietary intake of 51 professional soccer players with two different clubs was carried out by the seven day weighed intake method. Physical characteristics of the two groups of players were similar, with only small differences in age and body mass but no difference in height and body fat. Mean (SD) daily energy intake for club A was 11.0 (2.6) MJ, and for club B 12.8 (2.2) MJ. The higher energy intake at club B was largely accounted for by a higher (P macronutrients to total energy intake was broadly similar to that of the general population.

    There is increasing pressure in veterinary education to teach and assess communication skills, with the Objective Structured Clinical Examination (OSCE) being the most common assessment method. Previous research reveals that raters are a large source of variance in OSCEs. This study focused on examining the effect of raters' professional background as a source of variance when assessing students' communication skills. Twenty-three raters were categorized according to their professional background: clinical sciences (n=11), basic sciences (n=4), clinical communication (n=5), or hospital administrator/clinical skills technicians (n=3). Raters from each professional background were assigned to the same station and assessed the same students during two four-station OSCEs. Students were in year 2 of their pre-clinical program. Repeated-measures ANOVA results showed that OSCE scores awarded by the rater groups differed significantly: (F(matched_station_1) [2,91]=6.97, p=.002), (F(matched_station_2) [3,90]=13.95, p=.001), (F(matched_station_3) [3,90]=8.76, p=.001), and ((Fmatched_station_4) [2,91]=30.60, p=.001). A significant time effect between the two OSCEs was calculated for matched stations 1, 2, and 4, indicating improved student performances. Raters with a clinical communication skills background assigned scores that were significantly lower compared to the other rater groups. Analysis of written feedback provided by the clinical sciences raters showed that they were influenced by the students' clinical knowledge of the case and that they did not rely solely on the communication checklist items. This study shows that it is important to consider rater background both in recruitment and training programs for communication skills' assessment.

    Crystals of habu coagulation factor IX-binding protein have been obtained at pH 6.5 and 4.6 and characterized by X-ray diffraction. Coagulation factor IX-binding protein isolated from Trimeresurus flavoviridis (IX-bp) is a C-type lectin-like protein. It is an anticoagulant protein consisting of homologous subunits A and B. The subunits both contain a Ca 2+ -binding site with differing affinity (K d values of 14 and 130 µM at pH 7.5). These binding characteristics are pH-dependent; under acidic conditions, the affinity of the low-affinity site was reduced considerably. In order to identify which site has high affinity and also to investigate the Ca 2+ -releasing mechanism, IX-bp was crystallized at pH 6.5 and 4.6. The crystals at pH 6.5 and 4.6 diffracted to 1.72 and 2.29 Å resolution, respectively; the former crystals belong to the monoclinic space group P2 1 , with unit-cell parameters a = 60.7, b = 63.5, c = 66.9 Å, β = 117.0°, while the latter belong to the monoclinic space group C2, with a = 134.1, b = 37.8, c = 55.8 Å, β = 110.4°

    Background: Hamstring injuries are the second most common injury causing missed days in professional baseball field players. Recent studies have shown the preventive benefit of eccentric conditioning on the hamstring muscle group in injury prevention. Specifically, Nordic-type exercises have been shown to decrease the incidence of acute hamstring injuries in professional athletes. Purpose: This was a prospective study performed in coordination with a single Major League Baseball (MLB) organization (major and minor league teams) that targeted the effects of Nordic exercises on the incidence of acute hamstring injuries in the professional-level baseball player. Study Design: Prospective cohort study; Level of evidence, 2. Methods: The daily workouts of 283 professional baseball players throughout all levels of a single MLB organization were prospectively recorded. The intervention group participated in the Nordic exercise program and was compared with a randomly selected control group of professional athletes within the organization not participating in the exercise program. The incidence of hamstring injuries in both groups was compared, and the total number of days missed due to injury was compared with the 2 previous seasons. Results: There were 10 hamstring injuries that occurred during the 2012 season among the 283 professional athletes that required removal from play. There were no injuries that occurred in the intervention group (n = 65, 0.00%; P = .0381). The number needed to treat (NNT) to prevent 1 hamstring injury was 11.3. The average repetitions per week of the injured group were assessed at multiple time points (2, 4, 6, and total weeks) prior to injury. There were significantly fewer repetitions per week performed in the injured group at all time points compared with overall average repetitions per week in the noninjured group (P = .0459, .0127, .0164, and .0299, respectively). After beginning the Nordic exercise program, there were 136 total days

  20. Degradation of p53 by human Alphapapillomavirus E6 proteins shows a stronger correlation with phylogeny than oncogenicity.

    Full Text Available Human Papillomavirus (HPV E6 induced p53 degradation is thought to be an essential activity by which high-risk human Alphapapillomaviruses (alpha-HPVs contribute to cervical cancer development. However, most of our understanding is derived from the comparison of HPV16 and HPV11. These two viruses are relatively distinct viruses, making the extrapolation of these results difficult. In the present study, we expand the tested strains (types to include members of all known HPV species groups within the Alphapapillomavirus genus.We report the biochemical activity of E6 proteins from 27 HPV types representing all alpha-HPV species groups to degrade p53 in human cells. Expression of E6 from all HPV types epidemiologically classified as group 1 carcinogens significantly reduced p53 levels. However, several types not associated with cancer (e.g., HPV53, HPV70 and HPV71 were equally active in degrading p53. HPV types within species groups alpha 5, 6, 7, 9 and 11 share a most recent common ancestor (MRCA and all contain E6 ORFs that degrade p53. A unique exception, HPV71 E6 ORF that degraded p53 was outside this clade and is one of the most prevalent HPV types infecting the cervix in a population-based study of 10,000 women. Alignment of E6 ORFs identified an amino acid site that was highly correlated with the biochemical ability to degrade p53. Alteration of this amino acid in HPV71 E6 abrogated its ability to degrade p53, while alteration of this site in HPV71-related HPV90 and HPV106 E6s enhanced their capacity to degrade p53.These data suggest that the alpha-HPV E6 proteins' ability to degrade p53 is an evolved phenotype inherited from a most recent common ancestor of the high-risk species that does not always segregate with carcinogenicity. In addition, we identified an amino-acid residue strongly correlated with viral p53 degrading potential.

    Legal expert opinions are a crucial instrument of professional self-control in medicine. To give impulses for further development, focus groups were initiated to reflect upon the perspective of legal dental experts. 5 focus group discussions on the topic "Professionalization of legal dental experts" were conducted. A total of 32 experienced legal dental experts participated in the discussions. The results were evaluated by qualitative content analysis. A catalogue of 68 ideas was generated for improvement and divided into 15 categories. Among these were periodic quality circles, interprofessional exchange, supervision of novices and periodic feedback for legal dental experts and dentists. Self-reflection can be included as an instrument for quality improvement of legal dental expert opinions. © Georg Thieme Verlag KG Stuttgart · New York.

    A new synthetic route to obtain the carboxylate analog of mannose 6-phosphate (M6-P) is presented. The effects of the M6-P, the carboxylate and two other analogs (the phosphonate and the alpha,beta ethylenic carboxylate) on the proliferation of human keratinocytes and dermal fibroblasts as well as on the proliferation of a murine fibroblast cell line, 3T3-J2 are tested. We observed that M6-P is a potent inhibitor of proliferation of both fibroblasts and keratinocytes. Among its analogs, the phosphonate showed a similar effect on human dermal fibroblasts but not on keratinocytes.

    The HEPiX (http://www.hepix.org) IPv6 Working Group has been investigating the many issues which feed into the decision on the timetable for the use of IPv6 (http://www.ietf.org/rfc/rfc2460.txt) networking protocols in High Energy Physics (HEP) Computing, in particular in the Worldwide Large Hadron Collider (LHC) Computing Grid (WLCG). RIPE NCC, the European Regional Internet Registry (RIR), ran out ofIPv4 addresses in September 2012. The North and South America RIRs are expected to run out soon. In recent months it has become more clear that some WLCG sites, including CERN, are running short of IPv4 address space, now without the possibility of applying for more. This has increased the urgency for the switch-on of dual-stack IPv4/IPv6 on all outward facing WLCG services to allow for the eventual support of IPv6-only clients. The activities of the group include the analysis and testing of the readiness for IPv6 and the performance of many required components, including the applications, middleware, management and monitoring tools essential for HEP computing. Many WLCG Tier 1/2 sites are participants in the group's distributed IPv6 testbed and the major LHC experiment collaborations are engaged in the testing. We are constructing a group web/wiki which will contain useful information on the IPv6 readiness of the various software components and a knowledge base (http://hepix-ipv6.web.cern.ch/knowledge-base). This paper describes the work done by the working group and its future plans.

    Clinical research professionals are faced with decreased funding and increased workloads; innovative methods of professional development programs are necessary to accommodate these factors. This study evaluated the feasibility, perceived satisfaction, and value of using webinars to educate clinical research professionals on reporting adverse events commonly experienced in pediatric oncology clinical trials. The setting incorporated synchronous web-based educational technology. Constructivist learning provides the theoretical framework for this study. Participants evaluated the professional development program at 2 time points: (a) at the conclusion and (b) 4 to 6 weeks afterward, using survey method. Synchronous webinars were both economical and effective in educating clinical research professionals across institutional sites. Participants reported exceptionally high levels of satisfaction with the accessibility, scope, quality, and interactivity of the professional development program. The vast majority of participants reported that the education would assist with reporting adverse events in pediatric oncology clinical trials and this perception persisted into clinical practice. Although the results of this study were intended to guide future educational efforts of the Children's Oncology Group, they may also apply to other cooperative groups.

    Coat proteins of tailed, dsDNA phages and in herpesviruses include a conserved core similar to the bacteriophage HK97 subunit. This core is often embellished with other domains such as the telokin Ig-like domain of phage P22. Eighty-six P22-like phages and prophages with sequenced genomes share a similar set of virion assembly genes and, based on comparisons of twelve viral assembly proteins (structural and assembly/packaging chaperones), these phages are classified into three groups (P22-like, Sf6-like, and CUS-3-like). We used cryo-electron microscopy and 3D image reconstruction to determine the structures of Sf6 procapsids and virions ({approx} 7 A resolution), and the structure of the entire, asymmetric Sf6 virion (16-A resolution). The Sf6 coat protein is similar to that of P22 yet it has differences in the telokin domain and in its overall quaternary organization. Thermal stability and agarose gel experiments show that Sf6 virions are slightly less stable than those of P22. Finally, bacterial host outer membrane proteins A and C were identified in lipid vesicles that co-purify with Sf6 particles, but are not components of the capsid.

    In the German health care system, multiprofessional and coordinated rehabilitation care provides support for successful disease management. Against a background of the conditions and strong dynamics of the provision, this article gives an overview of some of the pertinent developments in rehabilitation-related undergraduate education and advanced professional training of physicians, psychologists, and exercise therapy professions in Germany. Frequently, there are few provisions and great variation between different locations. New conditions, such as the National Competence-Based Learning Objectives for Undergraduate Medical Education, the National Guidelines for Graduate Medical Education, and the ongoing reform of the psychotherapists' law emphasizing training in psychotherapy at university, allow the expectation of a positive effect on the competence of rehabilitation professionals. Education in physiotherapy is developing according to international standards aimed at improved evidence-based care. For the widely evidence-based undergraduate education and advanced professional training in sports and exercise therapy better profiling and professionalization should be sought.

    To assess the view of a group of Primary care professionals on their level of perception of group cohesiveness in their teams' work dynamic. A descriptive and sectional study. Four urban health centres in Salamanca with a recognised teaching activity. Both health professionals and those outside the Health Service, working in Primary Care, who had been members of their teams for more than a year (N = 90). Descriptive statistics and "Chi squared" tests were employed. 72%. A high level of agreement on the need for team work (95.23%). They perceived their group cohesiveness as being very low (84.21% affirmed that they encounter problems of cohesiveness). The main statements concerning this lack of cohesiveness were: "lack of common objectives" (25.5%), "intolerance between workers" (20.13%), "work not shared" (19.46%) and "the taking of decisions individually" (19.44%). The main causes given were: lack of support from Management (23.74%) and too little training for team work (21.58%). There is a high degree of conviction that the team work model is the most efficacious way of developing Primary Care. However in three of the four teams questioned, there were serious problems preventing the teams' reaching an adequate level of group cohesiveness.

    This article analyzes the significance that health professionals attribute to health education groups for people with Type 2 Diabetes Mellitus (T2DM). This ethnographic study was developed with five professionals from an Expanded Family Health team that operated in five diabetes health education groups. Information was gathered using participant observations and semi-structured interviews. Data were analyzed by means of a thematic coding technique. Three different categories emerged: (1) It is a way of educating them: groups as an educational and clinical monitoring forum; (2) they know I will be there for them: the groups as a resource to access the health system; and (3) this serves as a self-help group: after all, what purpose does this group serve? The conclusion reached is that the groups studied were a therapy and support hybrid that, by means of their structure, made it possible for the informants (perhaps, also for the patients) to construct other significance for the standardization of health policies and the dilemma of chronicity. Such hybridization made it possible to create outcomes for the specificities of health work in a "total life" context.

    The extent to which health and social care (HSC) students hold stereotypical views of other HSC professional groups is of great potential importance to team working in health care. This paper explores students' perceptions of different HSC professional groups at the beginning of their university programmes. Findings are presented from an analysis of baseline data collected as part of the New Generation Project longitudinal cohort study which is assessing the impact of interprofessional education over time on a range of variables including stereotyping. Questionnaires were administered to a cohort of over 1200 students from 10 different HSC professional groups entering their first year of university. Stereotypes were measured using a tool adapted from Barnes et al. (2000) designed to elicit stereotype ratings on a range of nine characteristics. The findings confirm that students arrive at university with an established and consistent set of stereotypes about other health and social care professional groups. Stereotypical profiles were compiled for each professional group indicating the distinctive characteristics of the groups as well as the similarities and differences between groups.Midwives, social workers and nurses were rated most highly on interpersonal skills and on being a team player whilst doctors were rated most highly on academic ability. Doctors, midwives and social workers were perceived as having the strongest leadership role, whilst doctors were also rated most highly on decision making. All professions were rated highly on confidence and professional competence and, with the exception of social workers, on practical skills. A comparison of profiles for each professional group reveals that, for example, pharmacists and doctors were perceived as having very similar characteristics as were social workers, midwives and nurses. However, the profiles of nurses and doctors were perceived to be very different. The implications of these similarities and

    To describe the health and professional status of multiple sclerosis patients of working age and to compare a group of patients in work (group T1) with a group of unemployed patients (group T2). A case-controlled study was performed. In the course of a specific consultation with a neurologist, demographic, medical and professional data were gathering using a questionnaire. Descriptive and comparative statistical analyses were then performed. A total of 76 patients were included in the study: 54 were in work (group T1) and 22 were unemployed (group T2). Hence, the employment rate was 71%, with an average time since disease onset of nine years at the time of the study. Low educational level (p=0.02), disease progression (p=0.0001), the presence of motor symptoms (p=0.01), cerebellar symptoms (p=0.02) or cognitive symptoms (p=0.03), a worse EDSS (p=0.0001) and a job requiring force (p=0.05) or manual dexterity (p=0.05) were found to be negative factors. Employment in the public sector (p=0.003) or large companies (p=0.03) were found to be protective factors. Access to the workplace was better for currently employed patients (p=0.03). This study shows that differences exist within the MS patient population according to the professional situation. It underlines the importance of clinical and demographics variables as determinants of differences in employment status. Not surprisingly, unemployed patients are more likely to have been classified as handicapped workers. Factors linked to work-induced constraints did not emerge from the survey because the questionnaire items were not appropriate for addressing this latter issue.

    For decades hospitals have been "vertically" organized, with the risk that specialization leads to fragmented and one-sided views of patient care and treatment that may cause poor communication and coordination of care and treatment. Two years after the introduction of an orthogeriatric unit for elderly patients admitted with fragility fractures, we studied the involved healthcare professionals' perspectives and experiences with working in an interprofessional organization. We performed four focus groups interviews with 19 healthcare workers representing different professions. The interviews were analysed using systematic text condensation (STC). Three themes were identified: 1) A patient-centred approach, 2) An opportunity for professional growth and 3) The benefits of interprofessional collaboration. The interviewees emphasized in particular the systematic and frequent face-to-face communication enabled by the interprofessional team meetings as essential to their feeling of enhanced collegial solidarity. All groups expressed their respect for other groups' competences and their vital contributions to good orthogeriatric care. However, collaboration was challenged by the groups' divergent views of the patients and of the relevance of the information given in the weekly meetings. Heavy workloads were also mentioned. The opportunity for professional growth was also felt to be imperilled by some professionals. All participants indicated their view that the orthogeriatric organization had improved the quality of care and treatment. Furthermore, good communication, mutual respect for other professional competences and shared goals were found to have enhanced interprofessional collaboration and improved the sense of having a shared mission. However, differences in approaches and expectations continued to challenge the orthogeriatric model after 2 years. Neither did all professionals find orthogeriatric care professionally challenging.

    Of many diseases and disorders of the nervous system Parkinson's disease (PD) deserves a particular attention for its specific effects having an impact on the ability to undertake different forms of professional and economic activities. Due to the constantly growing incidence rate and the lowering age of patients, PD is becoming more and more serious social problem. The aim of this study was to determine the effects of professional work and physiotherapy on the quality of live in people with Parkinson's disease. The research was carried out on 109 people with diagnosed PD of stage II according to the Hoehn and Yahr classification. They were divided into professionally working and non-working subjects and those participating and not participating in physiotherapy programs. The Unified Parkinson's Disease Rating Scale (UPDRS), was used to estimate the patients' clinical status. The Parkinson's Disease Questionnaire (PDQ-39), the Quality of Life Short Form (SF-36) Questionnaire and the Parkinson's Disease Quality of Life Questionnaire (PDQL) were used to estimate the quality of life. In all groups statistically significant differences were observed in each of the used scale. The PDQ-39 (F = 5.278, p = 0.04), SF physical component (F = 4.24, p = 0.005), SF mental component (F = 3.45, p = 0.021), PDQL (F = 6.57, p = 0.003). The highest quality of life was noticed in people working professionally and participating in physiotherapy programs. Professional activity and participation in properly planned physiotherapy help reduce the symptoms and improve the quality of life of people with Parkinson's disease. The study showed that the quality of life of people with PD is determined by professional work and participation in the process of rehabilitation. Med Pr 2017;68(6):725-734.

    Professional practice education is a core and essential component of occupational therapy training. With increasing numbers of education programmes and more students requiring professional practice placements, development of innovative models of professional practice education has emerged, but these require investigation. The aim of this study was to investigate student experiences and perceptions of the Student-Led Groups Program model of professional practice education in an inpatient brain injury rehabilitation unit. A qualitative approach, guided by phenomenological theory was used. Participants were 15 students who had completed a professional practice placement in the Student-Led Groups Program. Data were collected using in-depth semi-structured interviews and analysed thematically. Three over-arching themes emerged from the data; balance of support and freedom, development of clinical skills and missed opportunities. Students described how the structure of the placement facilitated independent learning and autonomy that was balanced with support from clinicians and student peers. Students perceived that they had developed a breadth of clinical skills and also had missed some learning opportunities in this professional practice placement structure. Overall student perceptions of the Student-Led Groups Program were positive, supporting the continued use of this model of professional practice education in this setting. The results highlight the value of structured and consistent approaches for supervision, including the use of formal approaches to peer supervision in the initial stages of learning. © 2017 Occupational Therapy Australia.

    To learn the main operational, professional, and business characteristics of U.S. radiology group practices, researchers at the American College of Radiology surveyed these groups. Major findings included the following: Approximately 30% of groups provide only diagnostic radiologic services, a similar percentage provides only radiation therapy for oncologic patients, and the remainder provides both types of services. Forty-one percent of groups practice only in hospitals, 11% practice only in an office, and 48% practice in both settings. Diagnostic-only practices average 10,000-12,000 procedures per full-time equivalent radiologist per year. Groups typically require new members to be part of the group for almost 3 years before they become full partners. Formal call schedules are nearly universal among radiology groups. Groups are becoming increasingly involved with health maintenance organizations and other "alternative delivery systems," but fee-for-service remains by far the dominant source of groups' revenue. Most studied characteristics of groups are changing relatively slowly, and trends are generally toward increasing formalization of arrangements.

    Cerebral concussion is common in collision sports such as football, yet the chronic neurological effects of recurrent concussion are not well understood. The purpose of our study was to investigate the association between previous head injury and the likelihood of developing mild cognitive impairment (MCI) and Alzheimer's disease in a unique group of retired professional football players with previous head injury exposure. A general health questionnaire was completed by 2552 retired professional football players with an average age of 53.8 (+/-13.4) years and an average professional football playing career of 6.6 (+/- 3.6) years. A second questionnaire focusing on memory and issues related to MCI was then completed by a subset of 758 retired professional football players (> or = 50 yr of age). Results on MCI were then cross-tabulated with results from the original health questionnaire for this subset of older retirees. Of the former players, 61% sustained at least one concussion during their professional football career, and 24% sustained three or more concussions. Statistical analysis of the data identified an association between recurrent concussion and clinically diagnosed MCI (chi = 7.82, df = 2, P = 0.02) and self-reported significant memory impairments (chi = 19.75, df = 2, P = 0.001). Retired players with three or more reported concussions had a fivefold prevalence of MCI diagnosis and a threefold prevalence of reported significant memory problems compared with retirees without a history of concussion. Although there was not an association between recurrent concussion and Alzheimer's disease, we observed an earlier onset of Alzheimer's disease in the retirees than in the general American male population. Our findings suggest that the onset of dementia-related syndromes may be initiated by repetitive cerebral concussions in professional football players.

    Educating physicians and other health care professionals about the identification and treatment of patients who drink more than recommended limits is an ongoing challenge. An educational randomized controlled trial was conducted to test the ability of a stand-alone training simulation to improve the clinical skills of health care professionals in alcohol screening and intervention. The "virtual reality simulation" combined video, voice recognition, and nonbranching logic to create an interactive environment that allowed trainees to encounter complex social cues and realistic interpersonal exchanges. The simulation included 707 questions and statements and 1207 simulated patient responses. A sample of 102 health care professionals (10 physicians; 30 physician assistants or nurse practitioners; 36 medical students; 26 pharmacy, physican assistant, or nurse practitioner students) were randomly assigned to a no training group (n = 51) or a computer-based virtual reality intervention (n = 51). Professionals in both groups had similar pretest standardized patient alcohol screening skill scores: 53.2 (experimental) vs 54.4 (controls), 52.2 vs 53.7 alcohol brief intervention skills, and 42.9 vs 43.5 alcohol referral skills. After repeated practice with the simulation there were significant increases in the scores of the experimental group at 6 months after randomization compared with the control group for the screening (67.7 vs 58.1; P virtual reality simulation to demonstrate an increase in the alcohol screening and brief intervention skills of health care professionals.

    Teaching medical professionalism is increasingly acknowledged as an important aspect of medical education. The Professionalism Mini-Evaluation Exercise (P-MEX) is an assessment tool for evaluating medical professionalism, but no studies using it as a self-assessment instrument have been reported. This paper reports on a preliminary investigation of the Finnish version of the P-MEX instrument as an assessment and self-assessment measure. The sample in the present cross-sectional study comprised all 23 medical students and recent graduates (15 females and 8 males) participating in a summer school of psychiatry program in 2014. The two-month program combines clinical work with multifaceted teaching and intensive tutoring. At the end of the program, the participants' medical professionalism was assessed by the tutors and other members of the work community as well as the students themselves using the Finnish version of the P-MEX instrument. The P-MEX scores were compared, using the Friedman test. The mean values and SD for the P-MEX assessments were as follows: tutor assessment 3.26±0.21, work community assessment 3.32±0.26 and self-assessment 3.01±0.07. No significant gender differences were observed. The tutor and work community assessments were significantly correlated (r=0.573, p=0.040), but the self-assessment scores did not correlate with either of the other assessments. Overall, the students evaluated their skills significantly poorer in comparison to the other assessments. Although the small sample size limits the generalization of these preliminary results, the Finnish version of the P-MEX instrument appears to be a feasible measure of medical professionalism. The instrument can also be used as a self-assessment instrument, but subjective evaluations should be complemented with external assessments or feedback in order to take individual and cultural aspects into account.

    Surgical treatment for chondral defects of the knee in competitive running and jumping athletes remains controversial. This study evaluated the performance outcomes of professional basketball players in the National Basketball Association (NBA) who underwent microfracture. Data from 24 professional basketball players from 1997 to 2006 was obtained and analyzed. NBA player efficiency ratings (PER) were calculated for two seasons before and after injury. A control group of 24 players was used for comparison. Study group and control group demographics including age, NBA experience, and minutes per game demonstrated no statistical difference. Mean time to return to an NBA game was 30.0 weeks from the time of surgery. The first season after returning to competition PER and minutes per game decreased by 3.5 (P 0.05) and 3.0 min (P NBA game. On return to competition player performance and minutes per game are diminished.

    Full Text Available Background: Of many diseases and disorders of the nervous system Parkinson’s disease (PD deserves a particular attention for its specific effects having an impact on the ability to undertake different forms of professional and economic activities. Due to the constantly growing incidence rate and the lowering age of patients, PD is becoming more and more serious social problem. The aim of this study was to determine the effects of professional work and physiotherapy on the quality of live in people with Parkinson’s disease. Material and Methods: The research was carried out on 109 people with diagnosed PD of stage II according to the Hoehn and Yahr classification. They were divided into professionally working and non-working subjects and those participating and not participating in physiotherapy programs. The Unified Parkinson’s Disease Rating Scale (UPDRS, was used to estimate the patients’ clinical status. The Parkinson’s Disease Questionnaire (PDQ-39, the Quality of Life Short Form (SF-36 Questionnaire and the Parkinson’s Disease Quality of Life Questionnaire (PDQL were used to estimate the quality of life. Results: In all groups statistically significant differences were observed in each of the used scale. The PDQ-39 (F = 5.278, p = 0.04, SF physical component (F = 4.24, p = 0.005, SF mental component (F = 3.45, p = 0.021, PDQL (F = 6.57, p = 0.003. The highest quality of life was noticed in people working professionally and participating in physiotherapy programs. Conclusions: Professional activity and participation in properly planned physiotherapy help reduce the symptoms and improve the quality of life of people with Parkinson’s disease. The study showed that the quality of life of people with PD is determined by professional work and participation in the process of rehabilitation. Med Pr 2017;68(6:725–734

    There are a variety of resources to obtain health information, but few studies have examined if main and allied health professionals prefer different methods. The current study was to investigate their information-searching behaviours. A constructed questionnaire survey was conducted from January through April 2011 in nationwide regional hospitals of Taiwan. Questionnaires were mailed to main professionals (physicians and nurses) and allied professionals (pharmacists, physical therapists, technicians and others), with 6160 valid returns collected. Among all professional groups, the most commonly used resource for seeking health information was a Web portal, followed by colleague consultations and continuing education. Physicians more often accessed Internet-based professional resources (online databases, electronic journals and electronic books) than the other groups (P < 0.05). In contrast, physical therapists more often accessed printed resources (printed journals and textbooks) than the other specialists (P < 0.05). And nurses, physical therapists and technicians more often asked colleagues and used continuing education than the other groups (P < 0.01). The most commonly used online database was Micromedex for pharmacists and MEDLINE for physicians, technicians and physical therapists. Nurses more often accessed Chinese-language databases rather than English-language databases (P < 0.001). This national survey depicts the information-searching pattern of various health professionals. There were significant differences between and within main and allied health professionals in their information searching. The data provide clinical implications for strategies to promote the accessing of evidence-based information. © 2012 John Wiley & Sons Ltd.

    The transition from student to medical doctor is challenging and stressful to many junior doctors. To practice with confidence and professionalism the junior doctors have to develop a strong professional identity. Various suggestions on how to facilitate formation of professional identity have been offered including the possible positive effect of group-coaching courses. The purpose of this study was to explore how group-coaching might facilitate professional identity formation among junior doctors in the transition period. Group-coaching courses comprising three whole-day sessions and five 2 h sessions during a period of 4 months were offered to junior doctors in the first years after graduation. The purpose was to support the participants' professional development, ability to relate to patients, relatives and staff and career development. The coaches in this study had a background as health professionals combined with coaching educations. Data was obtained through observations, open-ended questionnaires and interviews. A generic thematic analysis was applied. Forty-five doctors participated in six coaching groups. The three main themes emerging in the sessions were: Adoption to medical culture, career planning, and work/life-balance. The junior doctors found the coaching intervention highly useful in order to cope with these challenges. Furthermore, the group was a forum where the junior doctors could share thoughts and feelings with colleagues without being afraid that this would endanger their professional career. Many found new ways to respond to everyday challenges mainly through a new awareness of patterns of thinking and feeling. The participants found that the group-coaching course supported their professional identity formation (thinking, feeling and acting as a doctor), adoption to medical culture, career planning and managing a healthy work/life-balance. Further studies in different contexts are recommended as well as studies using other methods to

    Up to 80% of professional musicians are affected by playing-related musculoskeletal disorders, but data regarding the frequency of craniomandibular dysfunction (CMD) in professional orchestra musicians is scarce. To evaluate the frequency of CMD and its relation to musculoskeletal pain in various body regions. A questionnaire-based survey approach assessing CMD symptoms and musculoskeletal pain in professional orchestra players was adopted. Relative prevalence rates and prevalence ratios for different instrument groups were estimated. A total of 408 musicians completed the questionnaire (response rate 57%). Playing-related pain in the teeth or jaw was reported by 19-47% of musicians and TMJ pain by 15-34%, depending on the instrument group. Current pain in the face indicating a painful CMD was reported in 6-10% and related symptoms such as teeth grinding in 25-34%, jaw clenching in 33-42% and jaw locking in 11-18% of musicians. Females were 2.4 times (95% confidence intervals (CI) 1.49-3.84) more likely to report having had orofacial pain within the last month. Musicians reporting orofacial pain within the last month were 4.8 times (95% CI: 2.83-8.02) more likely to report pain in the neck and 2.5-3.8 times (P neck, shoulder and hands. There is a need to enhance awareness of CMD to optimize early medical diagnosis and treatment.

    This study compared differences in role conception (professional, bureaucratic, and service), role deprivation, and self-esteem among baccalaureate students enrolled in specially designed professional development seminars. More than 100 students participated in the pretests, given on entry to the program, of which 63 completed both the pretest and the posttest given on program exit. The Corwin Role Conception Scale assessed role conceptions and role deprivation and the Coopersmith Adult Form Self-Esteem Inventory assessed self-esteem. Statistically significant differences were found within groups in bureaucratic role conceptions (P = .0009) and self-esteem (P = .0019) and between groups in professional role conception (P = .0057). No differences were found between or within groups for service role conception or role deprivation.

    Genital herpes is one of 8 legally reportable sexually transmitted diseases (STD) in China. Using a HSV antigen ELISA kit we detected and typed HSV antigen in 1,148 clinical specimens collected from the genital organs (penis, cervix, vagina and vulva) of 446 men and 702 women in Qindao and divided into 11 different professional and 2 special groups (patients with cervical cancer and pregnant women). The highest positive rate of HSV antigen was found among long-distance transport drivers (48.0%). The second and third high positive rates were among waiters and waitresses in private, restaurants (39.2%) and patients with cervical cancer (38.2%). The positive rates among self-employed retailers and employees in private inns and restaurants were notably higher than those among employees in state-run shops, restaurants and hotels. And, the positive rate among workers was higher than that among peasants. There was no notable difference between the positive rate of HSV antigen among men (24.2%) and that among women (21.5%). But the incidence of HSV-2 infection was much higher than that of HSV-1 infection. The results indicate that some special professional groups have high rates of genital HSV infection. More attention needs to be paid to these special groups in order to control sexually transmitted herpes diseases.

    To develop an understanding of patient and health professional views and experiences of physiotherapy to manage joint hypermobility syndrome (JHS). An explorative qualitative design. Seven focus groups were convened, audio recorded, fully transcribed and analysed using a constant comparative method to inductively derive a thematic account of the data. Four geographical areas of the U.K. 25 people with JHS and 16 health professionals (14 physiotherapists and two podiatrists). Both patients and health professionals recognised the chronic heterogeneous nature of JHS and reported a lack of awareness of the condition amongst health professionals, patients and wider society. Diagnosis and subsequent referral to physiotherapy services for JHS was often difficult and convoluted. Referral was often for acute single joint injury, failing to recognise the long-term multi-joint nature of the condition. Health professionals and patients felt that if left undiagnosed, JHS was more difficult to treat because of its chronic nature. When JHS was treated by health professionals with knowledge of the condition patients reported satisfactory outcomes. There was considerable agreement between health professionals and patients regarding an 'ideal' physiotherapy service. Education was reported as an overarching requirement for patients and health care professionals. Physiotherapy should be applied holistically to manage JHS as a long-term condition and should address injury prevention and symptom amelioration rather than cure. Education for health professionals and patients is needed to optimise physiotherapy provision. Further research is required to explore the specific therapeutic actions of physiotherapy for managing JHS. Copyright © 2015 Chartered Society of Physiotherapy. Published by Elsevier Ltd.

    In this study we reconstruct the structural evolution of the hyper-variable P6b region of the group I trnLeu intron in a monophyletic group of lichen-symbiotic Nostoc strains and establish it as a useful marker in the phylogenetic analysis of these organisms. The studied cyanobacteria occur as photosynthetic and/or nitrogen-fixing symbionts in lichen species of the diverse Nephroma guild. Phylogenetic analyses and secondary structure reconstructions are used to improve the understanding of the replication mechanisms in the P6b stem-loop and to explain the observed distribution patterns of indels. The variants of the P6b region in the Nostoc clade studied consist of different combinations of five sequence modules. The distribution of indels together with the ancestral character reconstruction performed enables the interpretation of the evolution of each sequence module. Our results indicate that the indel events are usually associated with single nucleotide changes in the P6b region and have occurred several times independently. In spite of their homoplasy, they provide phylogenetic information for closely related taxa. Thus we recognize that features of the P6b region can be used as molecular markers for species identification and phylogenetic studies involving symbiotic Nostoc cyanobacteria.

  18. Chemical modification and pH dependence of kinetic parameters to identify functional groups in a glucosyltransferase from Strep. Mutans

    Bell, J.E.; Leone, A.; Bell, E.T.

    1986-01-01

    A glucosyltransferase, forming a predominantly al-6 linked glucan, was partially purified from the culture filtrate of S. mutans GS-5. The kinetic properties of the enzyme, assessed using the transfer of 14 C glucose from sucrose into total glucan, were studied at pH values from pH 3.5 to 6.5. From the dependence of km on pH, a group with pKa = 5.5 must be protonated to maximize substrate binding. From plots of V/sub max/ vs pH two groups, with pKa's of 4.5 and 5.5 were indicated. The results suggest the involvement of either two carboxyl groups (one protonated, one unprotonated in the native enzyme) or a carboxyl group (unprotonated) and some other protonated group such as histidine, cysteine. Chemical modification studies showed that Diethylyrocarbonate (histidine specific) had no effect on enzyme activity while modification with p-phydroxy-mercuribenzoate or iodoacetic acid (sulfhydryl reactive) and carbodimide reagents (carboxyl specific) resulted in almost complete inactivation. Activity loss was dependent upon time of incubation and reagent concentration. The disaccharide lylose, (shown to be an inhibitor of the enzyme with similar affinity to sucrose) offers no protection against modification by the sulfhydryl reactive reagents

    The present study aims to test whether sense of coherence (SOC) acts as a determinant of positive psychological functioning in aid workers directly exposed to warfare. Specifically, we performed multiple regression analyses to compare different groups of aid workers in terms of the effects of SOC and cumulative trauma on their psychological distress. Palestinian helpers, both professional and non-professional (N = 159) completed three self-reported measures: the General Health questionnaire, Sense of Coherence Scale, and Impact of Events Scale. The findings bear out the predictive power of SOC and posttraumatic stress disorder (PTSD) in relation to mental health across different professional groups. In particular, volunteers without a specific professional profile, psychiatrists, medical doctors, and less markedly counselors seemed to protect their mental health through a SOC. Clinical implications and recommendations for training and supervision are discussed. © The Author(s) 2015.

    Stepping Stones Triple P (SSTP) is a parenting program designed for families of a child with a disability. The current study involved a randomized controlled trial of Group Stepping Stones Triple P (GSSTP) for a mixed-disability group. Participants were 52 families of children diagnosed with an Autism Spectrum Disorder, Down syndrome, Cerebral Palsy, or an intellectual disability. The results demonstrated significant improvements in parent-reported child behavior, parenting styles, parental satisfaction, and conflict about parenting. Results among participants were similar despite children's differing impairments. The intervention effect was maintained at 6-month follow-up. The results indicate that GSSTP is a promising intervention for a mixed-disability group. Limitations of the study, along with areas for future research, are also discussed. © FPI, Inc.

    Full Text Available The purposes of this study were to determine whether low intensity resistance training combined with blood flow restriction (LI-BFR could affect the concentric hamstrings/quadriceps muscle strength ratio (Hcon:Qcon of professional soccer players with Hcon:Qcon imbalance (Study 1, and whether hamstrings strength response observed after LI-BFR is associated with muscle hypertrophy (Study 2. In the Study 1, athletes were randomly divided into a training group (n = 6 and a control group (n = 5. In the Study 2, all athletes (n = 11 have performed the training programme. The athletes participated in a 6-week (twice a week supervised training programme (unilateral knee flexion at 30% 1RM consisting of 12 training sessions. Peak concentric torque of knee flexors (+8%; P < 0.001 and Hcon:Qcon (+9%; P < 0.01 were significantly increased after LI-BFR. Moreover, the cross sectional area (CSA of the hamstrings was significantly increased (+10%; P < 0.001 after LI-BFR. Thus, the addition of hamstrings strength training programme using LI-BFR during preseason is able to enhance both Hcon:Qcon and hamstrings CSA of professional soccer players with Hcon:Qcon imbalance.

    Finite groups with two independent generators attracted the attention of authors for several years. The author, having started on such groups in his PhD Thesis in 1953, discussed later on the existence and the structure of finite groups with three generators, one being of arbitrary order and the other two having given orders [Pub. Math. Debrecen, 11, 32-38(1964), 13, 9-16(1966)] and others. Recently, the author started the problem of finite groups with four generators a,b,c and d when b,c and d have the same odd prime order p. It is the object of the present paper to deal with a similar problem when the given orders are p, p and q with p q together with the particular case when m is an element of set containing p,q will be kept to a further discussion. The present paper consists actually of two main parts, the first deals with the case p does not divide q-1 while the second deals with the case p divides q-1. (author)

    The Spanish model is the model adopted by many countries to increase their donation rate, being the implication of the healthcare professionals one of the keys to this success. The attitude of these before the donation is crucial for the hour of influence on the population. Organ transplantation has been established as an effective treatment that has been improving over the years. The objective was to determine the knowledge and attitudes of health professionals before the donation of organs. Cross-sectional descriptive study. An ad hoc questionnaire was conducted and distributed among the health professionals (medical staff, nurses and nursing assistants) of a tertiary hospital during February 2015. A total of 615 potential participants were estimated in the different areas of the hospital. A total of 342 completed questionnaires were collected (55%). The statistical analysis with SPSS® Statistics for Windows. Version 20.0. A level of significance P lower than 0.05 was used in all the analyses. The average age of the respondents was 43.34 (SD = 10.37) years, being 86.6% women and 60% nurses. 35.5% showed good knowledge about the donation process, being higher in men (51.1% Vs 33.1%, p lower than 0.05), medical personnel (55% vs 34.3% vs 31.9%). %; p lower than 0.05) and lower in those services with a direct relationship with the donation process (36.8% vs 31.9%, p lower than 0.05). 71% of the professionals expressed their willingness to donate their organs, with special sensitivity towards donation those services in direct relation with the donation program (82.2% vs 65.9%, OR: 1.24, p lower than 0.001 ). 50% of the professionals would donate the organs of a family member; the medical group had the highest percentage (70% vs 50.7% vs 40.4%, OR: 3.8, p lower than 0.05). 74.5% knew some Spanish legal document about donation and transplants. Health professionals as a whole have a low level of knowledge; but a good attitude towards donation.

    Antimicrobial photodynamic therapy (APDT) is a novel technique to treat local infections. Previously we reported that the attachment of chlorin(e6) to polyethylenimine (PEI) polymers to form PEI-ce6 conjugates is an effective way to improve ce6 PDT activity against bacteria. The aim of this work was to explore how the polymer molecular weight, substitution ratio (SR) of ce6 and pH value affect the PDT efficacy. We have synthesized PEI-ce6(10) (MW = 60,000, SR = 1) and PEI-ce6(11) (MW = 60,000, SR = 5) and compared these with the previous PEI-ce6(9) (MW = 10,000, SR = 1). We tested the PDT efficacy of these three conjugates against Gram-negative E. coli and Gram-positive bacteria (S. aureus and E. fecalis) at three different pH values (5.0, 7.4, 10.0) that may affect the charge on both the bacterial cells and on the conjugate (that has both basic and acidic groups). PEI-ce6(9) and PEI-ce6(10) were the most effective against these tested bacteria. The PDT effect of all three conjugates depended on pH values. The effective order was pH = 10.0 > pH = 7.4 > pH = 5.0 on E. coli. For S. aureus and E. fecalis the order was pH = 5.0 > pH = 10.0 > pH = 7.4. PEI-ce6(11) PDT activity was worse than PEI-ce6(10) activity which is probably connected to the fact that ce6 molecules are self-quenched within the PEI-ce6(11) molecule. Ce6 quenching within the PEI-ce6 molecules was proved by analyzing fluorescence spectra of PEI-ce6 conjugates at different pH values. There were no differences in bacterial uptake between different pH values in three PEI-ce6 conjugates. We assume high pH (rather than low pH as was hypothesized) disaggregates the conjugates, so the higher pH was more effective than the lower pH against E. coli. But for Gram-positive bacteria, low pH was more effective possibly due to more overall positive charge on the conjugate. Copyright © 2011 Wiley-Liss, Inc.

    Training at the optimal load for peak power output (PPO) has been proposed as a method for enhancing power output, although others argue that the force, velocity, and PPO are of interest across the full range of loads. The aim of this study was to examine the influence of load on PPO, peak barbell velocity (BV), and peak vertical ground reaction force (VGRF) during the jump squat (JS) in a group of professional rugby players. Eleven male professional rugby players (age, 26 ± 3 years; height, 1.83 ± 6.12 m; mass, 97.3 ± 11.6 kg) performed loaded JS at loads of 20-100% of 1 repetition maximum (1RM) JS. A force plate and linear position transducer, with a mechanical braking unit, were used to measure PPO, VGRF, and BV. Load had very large significant effects on PPO (p < 0.001, partial η² = 0.915); peak VGRF (p < 0.001, partial η² = 0.854); and peak BV (p < 0.001, partial η² = 0.973). The PPO and peak BV were the highest at 20% 1RM, though PPO was not significantly greater than that at 30% 1RM. The peak VGRF was significantly greater at 1RM than all other loads, with no significant difference between 20 and 60% 1RM. In resistance trained professional rugby players, the optimal load for eliciting PPO during the loaded JS in the range measured occurs at 20% 1RM JS, with decreases in PPO and BV, and increases in VGRF, as the load is increased, although greater PPO likely occurs without any additional load.

  11. Quality science for all: A qualitative study of professional development and assessment implementation in STEP-uP

    Funk, Christine M.

    One of the most important factors in achieving scientific literacy is for science teachers at the local level to develop a greater understanding of science education, including science content, pedagogy, and assessment. This study was designed to examine the connection between teacher learning and practice by studying the relationship between professional development and assessment implementation in the elementary science classroom. The goal was to develop a deeper understanding of the components of the STEP-uP model that served as a catalyst for change and to provide insight into how to best work with teachers in order to develop a more scientifically literate population. Four essential questions guided this research. What kinds of opportunities does STEP-uP provide for elementary school teachers to improve their assessment practices in science? In what ways did STEP-uP training affect assessment practices by teachers? How, if at all, are the assessment practices modified by teachers? What are the most salient features of the STEP-uP professional development model that allow for change and growth in assessment practices in elementary science classrooms and for education at large? The research method for this study was educational connoisseurship and criticism. I developed rich descriptions and interpretations based on observations, interviews, and artifacts from six classroom teachers which were then compared and contrasted to the goals of STEP-uP described in their literature, by the assessment coordinator, and an observation of a STEP-uP training. Key findings include: (1) collaboration and collegial support must be integral to sustain change; (2) clearly articulated goals form one, cohesive vision for professional development that must be integral to all components of the program; (3) multiple entry points help encourage participation and honor differences between teachers' personal and professional needs; and, (4) classroom structures such as time, classroom

    Uneven distribution of the medical workforce is globally recognised, with widespread rural health workforce shortages. There has been substantial research on factors affecting recruitment and retention of rural doctors, but little has been done to establish the motives and conditions that encourage allied health professionals to practice rurally. This study aims to identify aspects of recruitment and retention of rural allied health professionals using qualitative methodology. Six focus groups were conducted across rural NSW and analysed thematically using a grounded theory approach. The thirty allied health professionals participating in the focus groups were purposively sampled to represent a range of geographic locations, allied health professions, gender, age, and public or private work sectors. Five major themes emerged: personal factors; workload and type of work; continuing professional development (CPD); the impact of management; and career progression. 'Pull factors' favouring rural practice included: attraction to rural lifestyle; married or having family in the area; low cost of living; rural origin; personal engagement in the community; advanced work roles; a broad variety of challenging clinical work; and making a difference. 'Push factors' discouraging rural practice included: lack of employment opportunities for spouses; perceived inadequate quality of secondary schools; age related issues (retirement, desire for younger peer social interaction, and intention to travel); limited opportunity for career advancement; unmanageable workloads; and inadequate access to CPD. Having competent clinical managers mitigated the general frustration with health service management related to inappropriate service models and insufficient or inequitably distributed resources. Failure to fill vacant positions was of particular concern and frustration with the lack of CPD access was strongly represented by informants. While personal factors affecting recruitment and

    The main aim of the study was to undertake training needs analysis among a multi-professional group for the purpose of improving care for ethnic minority patients and other service users. Evidence from the literature identifies that some of the explanations advanced for the failure of health professionals to meet the needs of ethnic minorities include lack of understanding of cultural diversities, racism, racial stereotyping, lack of knowledge, exclusivity, and ethnocentrism. While these issues have been addressed in different countries, little work has been carried out to examine these from the perspective of health professionals caring for ethnic minorities. This study is therefore an attempt to find out what health professionals know about caring for patients and other service users from minority ethnic groups and their perception of training needs in this area of work. A pre- and post-training design phase structured the qualitative approach. A purposive sample of individuals working across five health service organizations located in a multi-racial city yielded a multi-professional group of participants. Views of 22 participants were obtained by semi-structured interviews at a pretraining phase. Training needs of health professionals drew on Walklin's (1992) six stages used to structure data collection, data analysis and delivery of training. The post-training phase used questionnaires to evaluate immediate learning that based on a 4-week period of reflection and applied to practice. The questionnaires were complemented by a facilitator-lead focus group. The majority of the participants confirmed that no attention was given in their initial education to the health care needs of minority ethnic groups. Instead, participants engaged in self-initiated learning to improve their knowledge and understanding. The issue of communication was viewed with dissatisfaction and seen as affecting the sufficiency of caring for these patients. All participants rated meeting

    To investigate the perception of Oral and maxillofacial surgery by healthcare professionals, students and general public. A questionnaire form was created that listed ten clinical situations, and given by hand to 1200 individuals, divided into six groups: group 1, medical professionals; group 2, Specialties of dentistry; group 3, general dentists; group 4, medical students; group 5, dental students; and group 6, general public, each comprising 200 individuals. Respondents were asked to indicate who they would expect to treat them if they had one of the specified conditions listed in the questionnaire. We present the results and current awareness levels of this simple questionnaire. The present study addresses the common issue raised by many authors, 'What surgical education the speciality offers?' especially to medical professionals, medical students and general public to enhance an appropriate referral. Most of the respondents in groups 2, 3 and 5 agreed that specific conditions listed in the questionnaire were within the domain of oral and maxillofacial surgery, but such response was not seen in groups 1, 4 and 6 ( p  oral and maxillofacial surgery was found to be 50.2%. The onus of creating and improving the awareness and perception of our specialty lies on oral and maxillofacial surgeon. Unified efforts at individual as well as global level will help achieve this goal.

    Background: Youth participation in organized sports in the United States is rising, with many athletes focusing on a single sport at an increasingly younger age. Purpose: To retrospectively compare single-sport specialization in current high school (HS), collegiate, and professional athletes with regard to the rate and age of specialization, the number of months per year of single-sport training, and the athlete’s perception of injury related to specialization. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A survey was distributed to HS, collegiate, and professional athletes prior to their yearly preparticipation physical examination. Athletes were asked whether they had chosen to specialize in only 1 sport, and data were then collected pertaining to this decision. Results: A total of 3090 athletes completed the survey (503 HS, 856 collegiate, and 1731 professional athletes). A significantly greater percentage of current collegiate athletes specialized to play a single sport during their childhood/adolescence (45.2% of HS athletes, 67.7% of collegiate athletes, and 46.0% of professional athletes; P < .001). The age of single-sport specialization differed between groups and occurred at a mean age of 12.7 ± 2.4 (HS), 14.8 ± 2.5 (collegiate), and 14.1 ± 2.8 years (professional) (P < .001). Current HS (39.9%) and collegiate athletes (42.1%) recalled a statistically greater incidence of sport-related injury than current professional athletes (25.4%) (P < .001). The majority (61.7%) of professional athletes indicated that they believed specialization helps the athlete play at a higher level, compared with 79.7% of HS and 80.6% of collegiate athletes (P < .001). Notably, only 22.3% of professional athletes said they would want their own child to specialize to play only 1 sport during childhood/adolescence. Conclusion: This study provides a foundation for understanding current trends in single-sport specialization in all athletic levels. Current

    A Balint-oriented supervision group for physicians is described concentrating on the study of the patient-doctor relationship, the recognition and diagnosis of psychiatric problems, and the planning of psychiatric treatment. The group includes five general practitioners, a gynecologist, a dermatologist, a psychiatrist and a psychologist, who have met once a month for an hour over a period of 12 years. Interaction between the physicians and the mental health professionals is illustrated by two clinical examples. The group helps the physician recognize, tolerate and use his countertransference feelings, and facilitates the examination and treatment of patients suffering from psychiatric problems. In Balint-oriented group work, the focus can be moved from physical symptoms to include observation of the patient's emotional life and significant object relations, to the factors that are crucial for his psychological balance. This kind of holistic observation in the examination and treatment of psychiatric problems is as important as appropriate laboratory investigations in the diagnosis and care of physical diseases.

    Implementation of evidence-based practice (EBP) is a complex task. This study, conducted in an acute geriatric setting, aims to compare self-reported capability beliefs on EBP between health professionals and students, and to compare the use of EBP between health professional groups. Occupational therapists, physicians, physiotherapists and registered nurses with three or more months’ employment, and all students from the occupational therapy, medical, physiotherapy and nursing programs, who had conducted workplace learning at the department, were invited. Data on capability beliefs and use of EBP were collected using the Evidence-based Practice Capabilities Beliefs Scale assessing six activities of EBP: formulate questions; search databases; search other sources; appraise research reports; participate in implementation in practice; and participate in evaluation. Descriptive and inferential statistics were used. Capability beliefs on EBP: The health professionals (n = 101; response rate 80%) reported high on search other sources but less on appraise research reports. The students (n = 124; response rate 73%) reported high on all EBP activities. The health professionals reported significantly higher on search other sources than the students. The students reported significantly higher on formulate questions and appraise research reports than the health professionals. No significant differences were identified between the health professional groups or between the student groups. Use of EBP: Health professionals reported wide-ranging use from several times each month to once every six months. The physicians reported significantly more frequent use than registered nurses and occupational therapists. Health professionals supervising students reported more frequent use of appraise research reports than the non-supervising group. There is a need for improving the use of EBP, particularly among registered nurses and occupational therapists. Supervision of students might

Occupational therapists, physicians, physiotherapists and registered nurses with three or more months' employment, and all students from the occupational therapy, medical, physiotherapy and nursing programs, who had conducted workplace learning at the department, were invited. Data on capability beliefs and use of EBP were collected using the Evidence-based Practice Capabilities Beliefs Scale assessing six activities of EBP: formulate questions; search databases; search other sources; appraise research reports; participate in implementation in practice; and participate in evaluation. Descriptive and inferential statistics were used. Capability beliefs on EBP: The health professionals (n = 101; response rate 80% reported high on search other sources but less on appraise research reports. The students (n = 124; response rate 73% reported high on all EBP activities. The health professionals reported significantly higher on search other sources than the students. The students reported significantly higher on formulate questions and appraise research reports than the health professionals. No significant differences were identified between the health professional groups or between the student groups. Use of EBP: Health professionals reported wide-ranging use from several times each month to once every six months. The physicians reported significantly more frequent use than registered nurses and occupational therapists. Health professionals supervising students reported more frequent use of appraise research reports than the non-supervising group. There is a need for improving the use of EBP, particularly among registered nurses and occupational therapists. Supervision of

    We have derived the most general chirally invariant Lagrangian L{sub 6} for the meson sector at order p{sup 6}. The result provides an extension of the standard Gasser-Leutwyler Lagrangian L{sub 4} to one higher order, including as well all the odd intrinsic parity terms in the Lagrangian. The most difficult part of the derivation was developing a systematic strategy so as to get all of the independent terms and eliminate the redundant ones in an efficient way. The equation of motion terms, which are redundant in the sense that they can be transformed away via field transformations, are separated out explicitly. The resulting Lagrangian has been separated into groupings of terms contributing to increasingly more complicated processes, so that one does not have to deal with the full result when calculating p{sup 6} contributions to simple processes.

    Human cytochrome P450 (CYP) 2A6 enzyme has been proposed to play a role in cellular defence against chemical-induced oxidative stress. The encoding gene is regulated by various stress activated transcription factors. This paper demonstrates that p53 is a novel transcriptional regulator of the gene. Sequence analysis of the CYP2A6 promoter revealed six putative p53 binding sites in a 3 kb proximate promoter region. The site closest to transcription start site (TSS) is highly homologous with the p53 consensus sequence. Transfection with various stepwise deletions of CYP2A6-5′-Luc constructs – down to − 160 bp from the TSS – showed p53 responsiveness in p53 overexpressed C3A cells. However, a further deletion from − 160 to − 74 bp, including the putative p53 binding site, totally abolished the p53 responsiveness. Electrophoretic mobility shift assay with a probe containing the putative binding site showed specific binding of p53. A point mutation at the binding site abolished both the binding and responsiveness of the recombinant gene to p53. Up-regulation of the endogenous p53 with benzo[α]pyrene – a well-known p53 activator – increased the expression of the p53 responsive positive control and the CYP2A6-5′-Luc construct containing the intact p53 binding site but not the mutated CYP2A6-5′-Luc construct. Finally, inducibility of the native CYP2A6 gene by benzo[α]pyrene was demonstrated by dose-dependent increases in CYP2A6 mRNA and protein levels along with increased p53 levels in the nucleus. Collectively, the results indicate that p53 protein is a regulator of the CYP2A6 gene in C3A cells and further support the putative cytoprotective role of CYP2A6. - Highlights: • CYP2A6 is an immediate target gene of p53. • Six putative p53REs located on 3 kb proximate CYP2A6 promoter region. • The region − 160 bp from TSS is highly homologous with the p53 consensus sequence. • P53 specifically bind to the p53RE on the − 160 bp region. • HNF4

    Thermal diffusivity and thermal conductivity have been studied for the layered crystals CuInP2S6, CuInP2Se6 from 30 K to 350 K, showing a relevant thermal anisotropy. Heat is much more efficiently transferred within the layers than perpendicular to them. The ferrielectric transition in CuInP2S6 is proven to be clearly first order while the ferroelectric one in CuInP2Se6 has a weak first order character. The behavior of the thermal conductivity as a function of temperature in the ferroelectric phases shows that heat conduction is phonon driven. Disorder in the paraelectric phases due to hopping motions of Cu ions significantly reduces the thermal conductivity to extremely low values.

    PhP(2-SHC6H4)2 (PS2H2) reacts with WCl6 with reduction of tungsten to give the air-sensitive tungsten(IV) complex [W{PhP(2-SC6H4)2-kappa(3)S,S',P}2] (1). 1 is oxidised in air to [WO{PhPO(2-SC6H4)2-kappa(3)S,S',O}{PhP(2-SC6H4)2-kappa(3)S,S',P}] (2). The attempted synthesis of 2 by reaction of 1 with iodosobenzene as oxidising agent was unsuccessful. [W{P(2-SC6H4)3-kappa(4)S,S',S",P}2] (3) was formed in the reaction of P(2-SHC6H4)3 (PS3H3) with WCl6. The W(VI) complex 3 contains two PS3(3-) ligands, each coordinated in a tetradentate fashion resulting in a tungsten coordination number of eight. The reaction of 3 with AgBF4 yields the dinuclear tungsten complex [W2{P(2-SC6H4)3-kappa(4)S,S',S",P}3]BF4 (4). Complexes 1-4 were characterised by spectral methods and X-ray structure determination.

    Full Text Available Background/Aim. Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR and to emphasize the markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. Methods. During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. Results. Average BMI values in men were in the overweight range (26.5-27 kg/m2. Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm. Between the first and the last year of monitoring a statistically significant decrease in these values ranging from 93.4 ± 9.8 cm to 92.7 ± 9.5 cm (p < 0.001 was observed. All monitored anthropometric parameters in female professional soldiers were within normal limits. During the monitored period the proportion of overweight men gradually increased from 52% to 57.1% (p < 0.001. There were no

    The academic debate on cross-cultural interaction within the context of end-of-life care takes for granted that this interaction is challenging. However, few empirical studies have actually focused on what health care professionals think about this interaction. This study aimed to explore health care professionals' understandings of cross-cultural interaction during end-of-life care. Sixty end-of-life care professionals were recruited from eleven care units in Sweden to take part in focus group interviews. These interviews were analyzed using qualitative content analysis. The health care professionals interviewed talked about cross-cultural interaction in end-of-life care as interaction that brings about uncertainty, stress and frustration even though they had limited experience of this type of interaction. The focus group discussions brought attention to four specific challenges that they expected to meet when they care for patients with migrant backgrounds since they took for granted that they would have an ethno-cultural background that is different to their own. These challenges had to do with communication barriers, 'unusual' emotional and pain expressions, the expectation that these patients' families would be 'different' and the anticipation that these patients and their families lack knowledge. At the core of the challenges in question is the idea that cross-cultural interaction means meeting "the unknown". In addition, the end-of-life care professionals interviewed talked about patients whose backgrounds they did not share in homogenizing terms. It is against this backdrop that they worried about their ability to provide end-of-life care that is individualized enough to meet the needs of these patients. The study suggests that end-of-life care professionals who regard cross-cultural interaction in this manner could face actual challenges when caring for patients whose backgrounds they regard as "the unknown" since they anticipate a variety of challenges

    Full Text Available The hospitality industry is dependent on a professional staff to exceed guests’ expectations. Existing research has focused primarily on the various attributes necessary for success in the hospitality industry. The primary focus of this research was professionalism and hospitality students’ self-perception of their professional attributes. Data collected from a focus group of hospitality human resource managers were used to develop a professionalism scale. The scale produced five factors that explained 53.6% of the variance in the responses. Students were more likely to agree in their preparedness for the interview process, but less in agreement of their preparedness for workplace issues. This research provides an exploratory study into a student’s perception of his or her own professional abilities and could be used as a placement tool for human resource managers and a benchmark to determine student’s professional aptitude by hospitality management professors.

    Cancer survivors (CSs) frequently return to work, but little is known about work functioning after return to work (RTW). We aimed to identify barriers and facilitators of work functioning among CSs. Three focus groups were conducted with CSs (n = 6, n = 8 and n = 8) and one focus group with occupational health professionals (n = 7). Concepts were identified by thematic analysis, using the Cancer and Work model as theoretical framework to structure the results. Long-lasting symptoms (e.g. fatigue), poor adaptation, high work ethics, negative attitude to work, ambiguous communication, lack of support and changes in the work environment were mentioned as barriers of work functioning. In contrast, staying at work during treatment, open dialogue, high social support, appropriate work accommodations and high work autonomy facilitated work functioning. Not only cancer-related symptoms affect work functioning of CSs after RTW but also psychosocial and work-related factors. The barriers and facilitators of work functioning should be further investigated in studies with a longitudinal design to examine work functioning over time.

    Previous studies have compared the outcomes after open and endoscopic excision of an os trigonum in patients of mixed professions. No studies have compared the differences in outcomes between the 2 procedures in elite ballet dancers. From October 2005 to February 2010, 35 professional ballet dancers underwent excision of a symptomatic os trigonum of the ankle after a failed period of nonoperative treatment. Of the 35 patients, 13 (37.1%) underwent endoscopic excision and 22 (62.9%) open excision. We compared the outcomes, complications, and time to return to dancing. The open excision group experienced a significantly greater incidence of flexor hallucis longus tendon decompression compared with the endoscopic group. The endoscopic release group returned to full dance earlier at a mean of 9.8 (range 6.5 to 16.1) weeks and those undergoing open excision returned to full dance at a mean of 14.9 (range 9 to 20) weeks (p = .001). No major complications developed in either group, such as deep infection or nerve or vessel injury. We have concluded that both techniques are safe and effective in the treatment of symptomatic os trigonum in professional ballet dancers. Endoscopic excision of the os trigonum offers a more rapid return to full dance compared with open excision. Copyright © 2016 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

    For younger generations, unconstrained online social activity is the norm. Little data are available about perceptions among young medical practitioners who enter the professional clinical arena, while the impact of existing social media policy on these perceptions is unclear. The objective of this study was to investigate the existing perceptions about social media and professionalism among new physicians entering in professional clinical practice; and to determine the effects of formal social media instruction and policy on young professionals' ability to navigate case-based scenarios about online behavior in the context of professional medicine. This was a prospective observational study involving the new resident physicians at a large academic medical center. Medical residents from 9 specialties were invited to participate and answer an anonymous questionnaire about social media in clinical medicine. Data were analyzed using SAS 9.4 (Cary, NC), chi-square or Fisher's exact test was used as appropriate, and the correct responses were compared between different groups using the Kruskal-Wallis analysis of variance. Familiarity with current institutional policy was associated with an average of 2.2 more correct responses (P=.01). Instruction on social media use during medical school was related to correct responses for 2 additional questions (P=.03). On dividing the groups into no policy exposure, single policy exposure, or both exposures, the mean differences were found to be statistically significant (3.5, 7.5, and 9.4, respectively) (P=.03). In this study, a number of young physicians demonstrated a casual approach to social media activity in the context of professional medical practice. Several areas of potential educational opportunity and focus were identified: (1) online privacy, (2) maintaining digital professionalism, (3) safeguarding the protected health information of patients, and (4) the impact of existing social media policies.

    To establish the most effective approach and type of educational intervention for health professional students, to enable them to maintain a professionally safe online presence. This was a qualitative, multinational, multi-institutional, multiprofessional study. Practical considerations (availability of participants) led us to use a combination of focus groups and individual interviews, strengthening our findings by triangulating our method of data collection. The study gathered data from 57 nursing, medical and paramedical students across four sites in three countries (Aotearoa/New Zealand, Australia and Wales). A content analysis was conducted to clarify how and why students used Facebook and what strategies they thought might be useful to ensure professional usage. A series of emergent codes were examined and a thematic analysis undertaken from which key themes were crystallized. The results illuminated the ways in which students use social networking sites (SNS). The three key themes to emerge from the data analysis were negotiating identities, distancing and risks. Students expressed the wish to have material about professional safety on SNS taught to them by authoritative figures to explain "the rules" as well as by peers to assist with practicalities. Our interactive research method demonstrated the transformative capacity of the students working in groups. Our study supports the need for an educational intervention to assist health professional students to navigate SNS safely and in a manner appropriate to their future roles as health professionals. Because health professional students develop their professional identity throughout their training, we suggest that the most appropriate intervention incorporate small group interactive sessions from those in authority, and from peers, combined with group work that facilitates and enhances the students' development of a professional identity.

    We report the photoionization studies of cesium from the 6p 2 P 3/2 excited state to measure the photoionization cross section at and above the first ionization threshold, oscillator strength of the highly excited transitions, and extension in the Rydberg series. The photoionization cross section at the first ionization threshold is measured as 25 (4) Mb and at excess energies 0.02, 0.04, 0.07, and 0.09 eV as 21, 19, 17, and 16 Mb, respectively. Oscillator strength of the 6p 2 P 3/2 → nd 2 D 5/2 (23 ≤ n ≤ 60) Rydberg transitions has been extracted utilizing the threshold value of photoionization cross section and the recorded nd 2 D 5/2 photoionization spectra.

    There are few data demonstrating the specific extent to which surgical intervention for vocal fold nodules (VFN) improves vocal function in professional (PVU) and non-professional voice users (NVU). The objective of this study was to compare and quantify results after phonomicrosurgery for VFN in these patient groups. In a prospective clinical study, surgery was performed via microlaryngoscopy in 37 female patients with chronic VFN manifestations (38±12 yrs, mean±SD). Pre- and postoperative evaluations of treatment efficacy comprised videolaryngostroboscopy, auditory-perceptual voice assessment, voice range profile (VRP), acoustic-aerodynamic analysis, and voice handicap index (VHI-9i). The dysphonia severity index (DSI) was compared with the vocal extent measure (VEM). PVU (n=24) and NVU (n=13) showed comparable laryngeal findings and levels of suffering (VHI-9i 16±7 vs 17±8), but PVU had a better pretherapeutic vocal range (26.8±7.4 vs 17.7±5.1 semitones, p<0.001) and vocal capacity (VEM 106±18 vs 74±29, p<0.01). Three months postoperatively, all patients had straight vocal fold edges, complete glottal closure, and recovered mucosal wave propagation. The mean VHI-9i score decreased by 8±6 points. DSI increased from 4.0±2.4 to 5.5±2.4, and VEM from 95±27 to 108±23 (p<0.001). Both parameters correlated significantly (rs=0.82). The average vocal range increased by 4.1±5.3 semitones, and the mean speaking pitch lowered by 0.5±1.4 semitones. These results confirm that phonomicrosurgery for VFN is a safe therapy for voice improvement in both PVU and NVU who do not respond to voice therapy alone. Top-level artistic capabilities in PVU were restored, but numeric changes of most vocal parameters were considerably larger in NVU.

    A questionnaire survey was conducted among three groups that mainly differ in socioeconomic status and professional exposure to ionizing radiations. Seventy-seven (26.3%) of the respondents were professionally exposed to radiation, 35 (11.9%) were medical doctors without professional exposure and 177 (68.4%) belonged to the general population group. The level of anxiety toward radiation, expressed as a concernedness index, is significantly lower in people who are professionally exposed to radiation compared to medical doctors and general population (0.81±0.94, 1.42±1.21 and 1.72±1.34 respectively, p < 0.001). In a similar manner, concernedness index values varied with the education status, with lowest values among medical university graduates and highest among public school graduates (p < 0.001). Both university-graduated groups significantly differ from the non-university groups (p < 0.05). Knowledge about radiation and knowledge about emergency plans in nuclear accident/incident were also checked in relation with concernedness, the results confirming the hypothesis that better knowledge associates lower concernedness. The extent to which people accept the civil utilization of nuclear power is also related to concernedness and knowledge, significant associations having been found. The results suggest that a political decision in radiation matter requires a valid analysis of the public's understanding and acceptance. For that reason, it is important that radiological protection authorities develop new plans and materials for communicating with people, in order to improve knowledge upon ionizing radiation, irradiation risks and safety of nuclear energy application for civil purposes.

Consecutive sampling of people seen in the health district and the group of health professionals working in it. Two anonymous self-filled questionnaires with closed questions aimed at health professionals and a sample of patients (accuracy, 0.05; confidence, 95%; prevalence, 50%). The mean age of the 407 patients was 48.4 (SD, 17.2), with 63.6% women. 21 questionnaires were filled in by the professionals (91%), 12 by doctors, and 9 by nurses. Their mean age was 43.9 (SD, 7.5), and 71.4% were women. For common questions, 54.3% of patients were keen on seeing the screen, while professionals calculated this figure at 11%. 5.6% of patients thought computerisation had changed the relationship, whereas 31.6% of professionals did. 12.6% of patients thought it had made the visit longer, whereas 38.1% of the professionals thought it had. 10.6% of patients and 47.4% of professionals thought it had led to loss of confidentiality. The introduction of computers into consultations was accepted well. Professionals were more worried than patients about possible loss of confidentiality, and thought that there had been bigger changes in the doctor-patient relationship and that visits had become longer.

Overall, 296 professionals participated in this study, stratified by Brazilian regions and NASF groupings. Electronic interviews were conducted regarding the activities developed at the unity where each NASF professional worked. The main activities reported were gymnastics (40.1%, and walking (29.4%, having as their priority public elderly people (68.8%, groups of hypertensive and diabetic patients (30.9% and young people (48.3%, respectively. The most discussed topics in lectures and orientations was the importance of physical activity (51.4% and the second most cited was the prevention/treatment of comorbities (32.3%. The community spaces most utilized by Physical Education professionals to develop activities were: public squares, community centers and schools in the southeastern and southern regions of Brazil, and religious entities in the northeastern and Midwestern regions. In conclusion, in spite of the diversity of activities developed in different regions of Brazil, there is predominance of traditional Physical Education contents, which reflect the need of permanent education of such professionals to improve the quality of services offered to the community.

    The NASA-funded project, Improving 6th Grade Climate Literacy using New Media (CLINM), is designed to improve the climate literacy of California's 450,000 6th-grade students through teacher professional development that presents climate change as an engaging context for teaching earth science standards. The project fosters experience-based interaction among learners and encourages expressive creativity and idea-exchange via the web and social media. The heart of the CLINM project is the development of an online educator-friendly experience that provides content expert-reviewed, teacher-tested, standards-based educational resources, classroom activities and lessons that make meaningful connections to NASA data and images as well as new media tools (videos, web, and phone applications) based on the Green Ninja, a climate-action superhero who fights global warming by inspiring personal action (www.greenninja.info). In this session, we will discuss this approach to professional development and share a collection of teacher-tested CLINM resources. CLINM resources are grounded in earth system science; classroom activities and lessons engage students in exploration of connections between natural systems and human systems with a particular focus on how climate change relates to everyone's need for food, water, and energy. CLINM uses a team-based approach to resource development, and partners faculty in San José State University's (SJSU) colleges of Science, Education, and Humanities and the Arts with 6th-grade teachers from local school districts, a scientist from NASA Ames Research Center and climate change education projects at Stanford University, the University of Nebraska at Lincoln, and the University of Idaho. Climate scientists and other content experts identify relevant concepts and work with science educators to develop and/or refine classroom activities to elucidate those concepts; activities are piloted in pre-service science methods courses at SJSU and in

    This study is devoted to the theoretical investigation of the quasimolecular emission of Xe*-He and Kr*-He collision pairs near the Xe (5p 56s 1,3 P 1 - 5p 6 1 S 0) and Kr (4p 55s 1,3 P 1 - 4p 6 1 S 0) resonance atomic lines. The potential curves of the quasimolecules Xe(5p 56s) + He and Kr(4p 55s) + He have been obtained with the use of the effective Hamiltonian and pseudopotential methods. Based on these potential curves the processes of quasimolecular emission of Xe*+He and Kr*+He mixtures have been considered and the spectral distributions I(ħΔω) of photons emitted have been obtained in the framework of quasistatic approximation.

    Full Text Available Agropyron cristatum (L. Gaertn. (2n = 4x = 28, PPPP not only is cultivated as pasture fodder but also could provide many desirable genes for wheat improvement. It is critical to obtain common wheat-A. cristatum alien disomic addition lines to locate the desired genes on the P genome chromosomes. Comparative analysis of the homoeologous relationships between the P genome chromosome and wheat genome chromosomes is a key step in transferring different desirable genes into common wheat and producing the desired alien translocation line while compensating for the loss of wheat chromatin. In this study, six common wheat-A. cristatum disomic addition lines were produced and analyzed by phenotypic examination, genomic in situ hybridization (GISH, SSR markers from the ABD genomes and STS markers from the P genome. Comparative maps, six in total, were generated and demonstrated that all six addition lines belonged to homoeologous group 6. However, chromosome 6P had undergone obvious rearrangements in different addition lines compared with the wheat chromosome, indicating that to obtain a genetic compensating alien translocation line, one should recombine alien chromosomal regions with homoeologous wheat chromosomes. Indeed, these addition lines were classified into four types based on the comparative mapping: 6PI, 6PII, 6PIII, and 6PIV. The different types of chromosome 6P possessed different desirable genes. For example, the 6PI type, containing three addition lines, carried genes conferring high numbers of kernels per spike and resistance to powdery mildew, important traits for wheat improvement. These results may prove valuable for promoting the development of conventional chromosome engineering techniques toward molecular chromosome engineering.

    2016-01-01

    Background For younger generations, unconstrained online social activity is the norm. Little data are available about perceptions among young medical practitioners who enter the professional clinical arena, while the impact of existing social media policy on these perceptions is unclear. Objective The objective of this study was to investigate the existing perceptions about social media and professionalism among new physicians entering in professional clinical practice; and to determine the effects of formal social media instruction and policy on young professionals’ ability to navigate case-based scenarios about online behavior in the context of professional medicine. Methods This was a prospective observational study involving the new resident physicians at a large academic medical center. Medical residents from 9 specialties were invited to participate and answer an anonymous questionnaire about social media in clinical medicine. Data were analyzed using SAS 9.4 (Cary, NC), chi-square or Fisher’s exact test was used as appropriate, and the correct responses were compared between different groups using the Kruskal–Wallis analysis of variance. Results Familiarity with current institutional policy was associated with an average of 2.2 more correct responses (P=.01). Instruction on social media use during medical school was related to correct responses for 2 additional questions (P=.03). On dividing the groups into no policy exposure, single policy exposure, or both exposures, the mean differences were found to be statistically significant (3.5, 7.5, and 9.4, respectively) (P=.03). Conclusions In this study, a number of young physicians demonstrated a casual approach to social media activity in the context of professional medical practice. Several areas of potential educational opportunity and focus were identified: (1) online privacy, (2) maintaining digital professionalism, (3) safeguarding the protected health information of patients, and (4) the impact of

    Full Text Available Tobacco is a major preventable cause of premature morbidity and mortality. Health professionals are uniquely positioned to provide targeted interventions and should be empowered to provide cessation counselling that influence patient smoking. A cross-sectional national survey was administered to all third year students in four disciplines at the University of Malta. The Global Health Professional Student Survey (GHPSS questionnaire was distributed to collect standardised demographic, smoking prevalence, behavioural, and attitudinal data. 81.9% completed the questionnaire (n = 173/211. A positive significant association between tobacco smoke exposure at home and current smoking status was identified. Non-smokers regarded anti-tobacco policies more favourably than smokers, being more likely to agree with banning of tobacco sales to adolescents (OR 3.6; 95% CI: 2.5–5.3; p ≤ 0.001; and with a smoking ban in all public places (OR 8.9; 95% CI: 6.1–13.1; p ≤ 0.001. Non-smokers favoured a role for health professionals in promoting smoking cessation (OR 5.1; 95% CI: 3.1–8.5; p ≤ 0.001. Knowledge of antidepressants as tools for smoking cessation was also associated with a perceived role for skilled health professionals in cessation counselling (OR 4.9; 95% CI: 1.8–13.3; p = 0.002. Smoking negatively influences beliefs and attitudes of students toward tobacco control. There is a need to adopt a standard undergraduate curriculum containing comprehensive tobacco prevention and cessation training to improve their effectiveness as role models.

  13. Extension of the chiral perturbation theory meson Lagrangian to order p6

    1996-01-01

    We have constructed the most general chirally invariant Lagrangian scrL 6 for the meson sector at order p 6 . The result provides an extension of the standard Gasser-Leutwyler Lagrangian scrL 4 to one higher order, including as well all the odd intrinsic parity terms in the Lagrangian. The most difficult part of the construction was developing a systematic strategy so as to get all of the independent terms and eliminate the redundant ones in an efficient way. The claim to have obtained the most general Lagrangian relies on this systematic construction and on the elimination of redundant quantities using relations of which we are aware, rather than on a general formal proof of either completeness or independence. The open-quote open-quote equation-of-motion close-quote close-quote terms, which are redundant in the sense that they can be transformed away via field transformations, are separated out explicitly. The resulting Lagrangian has been separated into groupings of terms contributing to increasingly more complicated processes, so that one does not have to deal with the full result when calculating p 6 contributions to simple processes. copyright 1995 The American Physical Society

    The aim of this study was to compare the tolerability and efficacy of once-daily travoprost 0.004% versus latanoprost 0.005% for 6 weeks followed by 6 weeks of once-daily travoprost 0.004% in decreasing intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OH). This multicenter, randomized, doublemasked, active-controlled, parallel-group trial was conducted at 32 centers across Latin America. Patients aged > or =18 years with OAG or OH were randomly assigned to receive topical travoprost 0.004% or latanoprost 0.005% 1 drop QD (9 PM) for 6 weeks (masked phase). At 6 weeks, all patients were assigned to receive open-label travoprost 0.004% 1 drop QD (9 PM) for 6 additional weeks (open-label phase). Study visits were scheduled at weeks 1, 2, 4, 6, 8, and 12. At each study visit, IOP was measured at 5 PM (+/-1 hour; approximately 20 hours after study drug administration). IOP changes from baseline were combined (pooled) from the 1-, 2-, 4-, and 6-week data to provide a comparison between the 2 treatment groups. Ocular adverse events (AEs) were monitored using slit-lamp examination. A total of 302 patients were enrolled (travoprost group, 155 patients; latanoprost group, 147 patients). The mean (SD) age of the travoprost group was 61.9 (10.6) years; 60.6% were female; and 47.1% were white. The mean (SD) age of the latanoprost group was 60.5 (12.4) years; 62.6% were female; and 49.0% were white. Mean IOP values were not significantly different between the travoprost and latanoprost groups at baseline (24.7 vs 24.2 mm Hg) or 6 weeks; however, the between-group difference in reductions from baseline in pooled IOP during the masked phase of the study was statistically significant (-8.3 vs -7.5 mm Hg; P = 0.009). At weeks 6 and 12, mean lOP levels were 16.1 and 16.2 mm Hg, respectively, in the travoprost group and 16.4 and 16.1 mm Hg in the group that was switched from latanoprost to travoprost (all, P = NS).

    Full Text Available The purpose of this study is to investigate the Ferrans and Powers Quality of Life Index (QLI and its domains in Brazilian athletes. The sample comprised 219 athletes from six sports, and included 127 men and 92 women, with mean age of 23.1 years (±5.2. All participants were associated with a sports organization and participated in official competitions at the professional, semiprofessional, and amateur levels, and completed a self-report demographics survey and the QLI during one testing session. Kruskal–Wallis and Mann–Whitney U tests were utilized to compare differences between competitive levels and gender, respectively. Significant differences were reported between professional and amateur athletes for the socioeconomic (p = .016; professional: 17.2, amateur: 15.1 and psychological/spiritual (p = .011; professional: 24.3, amateur: 21.9 domains and between genders on the family domain (p = .027; male: 21.8, female: 20.2. These findings suggest that professional athletes are more satisfied from a socioeconomic and psychological/spiritual perspective when compared with the amateur group. In addition, the results suggest that family issues are more satisfying and/or have less importance for males than for females. This study provides further insights into the quality of life of athletes and suggests differences based on competition levels and gender. Future studies are needed to further our understanding of the quality of life in athletes.

    Modern dancers are a unique group of artists, performing a diverse repertoire in dance companies of various sizes. In this study, 184 professional modern dancers in the United States (males N=49, females N=135), including members of large and small companies as well as freelance dancers, were surveyed regarding their demographics and training characteristics. The mean age of the dancers was 30.1 +/- 7.3 years, and they had danced professionally for 8.9 +/- 7.2 years. The average Body Mass Index (BMI) was 23.6 +/- 2.4 for males and 20.5 +/- 1.7 for females. Females had started taking dance class earlier (age 6.5 +/- 4.2 years) as compared to males (age 15.6 +/- 6.2 years). Females were more likely to have begun their training in ballet, while males more often began with modern classes (55% and 51% respectively, p professional modern dancers surveyed spent 8.3 +/- 6.0 hours in class and 17.2 +/- 12.6 hours in rehearsal each week. Eighty percent took modern technique class and 67% reported that they took ballet technique class. The dancers who specified what modern technique they studied (N=84) reported between two and four different techniques. The dancers also participated in a multitude of additional exercise regimens for a total of 8.2 +/- 6.6 hours per week, with the most common types being Pilates, yoga, and upper body weightlifting. The dancers wore many different types of footwear, depending on the style of dance being performed. For modern dance alone, dancers wore 12 different types of footwear. Reflecting the diversity of the dancers and companies surveyed, females reported performing for 23.3 +/- 14.0 weeks (range: 2-52 weeks) per year; males reported performing 20.4 +/- 13.9 weeks (range: 1-40) per year. Only 18% of the dancers did not have any health insurance, with 54% having some type of insurance provided by their employer. However, 23% of the dancers purchased their own insurance, and 22% had insurance provided by their families. Only 16% of dancers

    In CPR, sufficient compression depth is essential. The American Heart Association ("at least 5cm", AHA-R) and the European Resuscitation Council ("at least 5cm, but not to exceed 6cm", ERC-R) recommendations differ, and both are hardly achieved. This study aims to investigate the effects of differing target depth instructions on compression depth performances of professional and lay-rescuers. 110 professional-rescuers and 110 lay-rescuers were randomized (1:1, 4 groups) to estimate the AHA-R or ERC-R on a paper sheet (given horizontal axis) using a pencil and to perform chest compressions according to AHA-R or ERC-R on a manikin. Distance estimation and compression depth were the outcome variables. Professional-rescuers estimated the distance according to AHA-R in 19/55 (34.5%) and to ERC-R in 20/55 (36.4%) cases (p=0.84). Professional-rescuers achieved correct compression depth according to AHA-R in 39/55 (70.9%) and to ERC-R in 36/55 (65.4%) cases (p=0.97). Lay-rescuers estimated the distance correctly according to AHA-R in 18/55 (32.7%) and to ERC-R in 20/55 (36.4%) cases (p=0.59). Lay-rescuers yielded correct compression depth according to AHA-R in 39/55 (70.9%) and to ERC-R in 26/55 (47.3%) cases (p=0.02). Professional and lay-rescuers have severe difficulties in correctly estimating distance on a sheet of paper. Professional-rescuers are able to yield AHA-R and ERC-R targets likewise. In lay-rescuers AHA-R was associated with significantly higher success rates. The inability to estimate distance could explain the failure to appropriately perform chest compressions. For teaching lay-rescuers, the AHA-R with no upper limit of compression depth might be preferable. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    In the nursing schools, the contrast between what is taught in the classrooms and what is practiced at the health care centers usually creates a great deal of confusion on the part of the students. The objective of this research is to ascertain the opinion of the students and of the professionals at the health care centers where they are doing their training with regard thereto in order to detect their problems and see what differences exist between primary and specialized care. This research was conducted throughout the first half of 2000 employing qualitative methodology, by means of four discussion groups comprised of students, former students, primary care training advisors and nursing professionals at the hospitals where the students of the school in question are doing their nursing training. The initial involvement employed was indirect. The comments of the nursing students and of their training advisors with regard to the practice nursing during the diploma studies reveal dissatisfaction on the part of both of these groups. In all of the groups point out anxiety as the leading factor involved in their teaching as well as learning activities and during professional training. The lack of identification as a group of professionals seems to be related to the lack of recognition on the part of the others, the demand for a degree being granted for their college studies and for the setting up of specialities would contribute to their social recognition and, as a result thereof, to their identification as a professional group. Until a solution is provided to the anxiety which the nursing professionals feel with regard to their professional practice, which they pass on to their students during nursing training, it will not be possible to achieve a higher degree of satisfaction with nursing training experiences either on the part of the training advisors or on the part of the students.

    The aim of the study was to analyse the effects of 6 week (15 sessions) flywheel resistance training with eccentric-overload (FRTEO) on different functional and anatomical variables in professional handball players. Twenty-nine athletes were recruited and randomly divided into two groups. The experimental group (EXP, n = 15) carried out 15 sessions of FRTEO in the leg-press exercise, with 4 sets of 7 repetitions at a maximum-concentric effort. The control group (CON, n = 14) performed the same number of training sessions including 4 sets of 7 maximum repetitions (7RM) using a weight-stack leg-press machine. The results which were measured included maximal dynamic strength (1RM), muscle power at different submaximal loads (PO), vertical jump height (CMJ and SJ), 20 m sprint time (20 m), T-test time (T-test), and Vastus-Lateralis muscle (VL) thickness. The results of the EXP group showed a substantially better improvement (p handball requires repeated short, explosive effort such as accelerations and decelerations during sprints with changes of direction, these results suggest that FRTEO affects functional and anatomical changes in a way which improves performance in well-trained professional handball players.

  1. Degradation Signals Recognized by the Ubc6p-Ubc7p Ubiquitin-Conjugating Enzyme Pair

    Proteolysis by the ubiquitin-proteasome system is highly selective. Specificity is achieved by the cooperation of diverse ubiquitin-conjugating enzymes (Ubcs or E2s) with a variety of ubiquitin ligases (E3s) and other ancillary factors. These recognize degradation signals characteristic of their target proteins. In a previous investigation, we identified signals directing the degradation of β-galactosidase and Ura3p fusion proteins via a subsidiary pathway of the ubiquitin-proteasome system involving Ubc6p and Ubc7p. This pathway has recently been shown to be essential for the degradation of misfolded and regulated proteins in the endoplasmic reticulum (ER) lumen and membrane, which are transported to the cytoplasm via the Sec61p translocon. Mutant backgrounds which prevent retrograde transport of ER proteins (hrd1/der3Δ and sec61-2) did not inhibit the degradation of the β-galactosidase and Ura3p fusions carrying Ubc6p/Ubc7p pathway signals. We therefore conclude that the ubiquitination of these fusion proteins takes place on the cytosolic face of the ER without prior transfer to the ER lumen. The contributions of different sequence elements to a 16-amino-acid-residue Ubc6p-Ubc7p-specific signal were analyzed by mutation. A patch of bulky hydrophobic residues was an essential element. In addition, positively charged residues were found to be essential. Unexpectedly, certain substitutions of bulky hydrophobic or positively charged residues with alanine created novel degradation signals, channeling the degradation of fusion proteins to an unidentified proteasomal pathway not involving Ubc6p and Ubc7p.

    Research shows that P2P scientific collaboration network will exhibit small-world topology, as do a large number of social networks for which the same pattern has been documented. In this paper we propose a topology building protocol to benefit from the small world feature. We find that the idea of Freenet resembles the dynamic pattern of social interactions in scientific data sharing and the small world characteristic of Freenet is propitious to improve the file locating performance in scientificdata sharing. But the LRU (Least recently used) datas-tore cache replacement scheme of Freenet is not suitableto be used in scientific data sharing network. Based onthe group locality of scientific collaboration, we proposean enhanced group clustering cache replacement scheme.Simulation shows that this scheme improves the request hitratio dramatically while keeping the small average hops per successful request comparable to LRU.

    We investigated the effect of abstract versus real-life meaningful images from sports on local contextual processing in two groups of professional athletes. Local context was defined as the occurrence of a short predictive series of stimuli occurring before delivery of a target event. EEG was recorded in 10 professional basketball players and 9 professional athletes of individual sports during three sessions. In each session, a different set of visual stimuli were presented: triangles facing left, up, right, or down; four images of a basketball player throwing a ball; four images of a baseball player pitching a baseball. Stimuli consisted of 15 % targets and 85 % of equal numbers of three types of standards. Recording blocks consisted of targets preceded by randomized sequences of standards and by sequences including a predictive sequence signaling the occurrence of a subsequent target event. Subjects pressed a button in response to targets. In all three sessions, reaction times and peak P3b latencies were shorter for predicted targets compared with random targets, the last most informative stimulus of the predictive sequence induced a robust P3b, and N2 amplitude was larger for random targets compared with predicted targets. P3b and N2 peak amplitudes were larger in the professional basketball group in comparison with professional athletes of individual sports, across the three sessions. The findings of this study suggest that local contextual information is processed similarly for abstract and for meaningful images and that professional basketball players seem to allocate more attentional resources in the processing of these visual stimuli.

    Pyrethroid insecticides are the front line vector control tools used in bed nets to reduce malaria transmission and its burden. However, resistance in major vectors such as Anopheles arabiensis is posing a serious challenge to the success of malaria control. Herein, we elucidated the molecular and biochemical basis of pyrethroid resistance in a knockdown resistance-free Anopheles arabiensis population from Chad, Central Africa. Using heterologous expression of P450s in Escherichia coli coupled with metabolism assays we established that the over-expressed P450 CYP6P4, located in the major pyrethroid resistance (rp1) quantitative trait locus (QTL), is responsible for resistance to Type I and Type II pyrethroid insecticides, with the exception of deltamethrin, in correlation with field resistance profile. However, CYP6P4 exhibited no metabolic activity towards non-pyrethroid insecticides, including DDT, bendiocarb, propoxur and malathion. Combining fluorescent probes inhibition assays with molecular docking simulation, we established that CYP6P4 can bind deltamethrin but cannot metabolise it. This is possibly due to steric hindrance because of the large vdW radius of bromine atoms of the dihalovinyl group of deltamethrin which docks into the heme catalytic centre. The establishment of CYP6P4 as a partial pyrethroid resistance gene explained the observed field resistance to permethrin, and its inability to metabolise deltamethrin probably explained the high mortality from deltamethrin exposure in the field populations of this Sudano-Sahelian An. arabiensis. These findings describe the heterogeneity in resistance towards insecticides, even from the same class, highlighting the need to thoroughly understand the molecular basis of resistance before implementing resistance management/control tools.

    Full Text Available Background: Infants are the most vulnerable people with special needs in natural disasters. Since midwives are responsible for providing reproductive health services to infants in disastrous situations, assessing their professional competence is of great importance. Materials and Methods: This cross-sectional study was conducted in Tehran, Iran. A total of 361 midwives were selected by cluster sampling method. After giving their informed consents, they participated in the study and completed the researcher-made questionnaire about providing health services to infants in natural disasters. Midwives’ professional competence was investigated through self-assessment in terms of their perceived importance, knowledge, and skill. Then, the data were analyzed using SPSS. Results: Mean(SD total score of professional competency of midwives in providing services to infants in disasters was 91.95(20.2 obtained from 3 subcategories: perceived importance, 39.83(9.55; knowledge, 22.5(5.06; and skill 30.16(6.86. There were significant relationships between the scores of professional competency of midwives with age (P=0.053, degree of education (P=0.028, the workplace (P=0.053, and experience in disaster (P=0.047. About 49.86% of midwives demonstrated middle level of professional competency. The lowest knowledge and skill score were reported in managing common neonatal problems such as asphyxia, sepsis, physical trauma, which requires referral and stability. Conclusion: The average scores of professional competency of midwives to deliver reproductive health service to infants in disasters shows the necessity of related and integrated education. It is recommended that by holding training exercises and simulations, midwives be educated with regard to disasters and how to respond in these situations.

    Objective: Recent investigation has underlined the potential of quantitative MR imaging to be used as a complementary tool for the diagnosis of cartilage degeneration at an early state. The presented study analyses T2* relaxation times of articular cartilage of the knee in professional athletes and compares the results to age- and BMI (Body Mass Index)-matched healthy amateur athletes. Materials and methods: 22 professional football players and 22 age- and BMI-matched individuals were underwent knee Magnetic Resonance Imaging (MRI) at 3T including qualitative and quantitative analysis. Qualitative analysis included e.g. meniscal tears, joint effusion and bone edema. For quantitative analysis T2* (22 ET: 4.6-53.6 ms) measurements in 3D data acquisition were performed. Deep and superficial layers of 22 predefined cartilage segments were analysed. All data sets were postprocessed using a dedicated software tool. Statistical analysis included Student t-test, confidence intervals and a random effects model. Results: In both groups, T2* relaxation times were significantly higher in the superficial compared to the deep layers (p < 0.001). Professional athletes had significantly higher relaxation times in eight superficial and three deep cartilage layers in the predefined cartilage segments (p < 0.05). Highly significant differences were found in the weight-bearing segments of the lateral superficial femoral condyle (p < 0.001). Conclusion: Elevated T2* values in cartilage layers of professional football players compared to amateur athletes were noted. The effects seem to predominate in superficial cartilage layers.

    There is a need for various types of interventions when meeting needs of clients with psychiatric disabilities and complementary interventions may also influence their well-being. The Culture and Health project, based on complementary interventions with 270 clients, was created in a county in Sweden for clients with psychiatric disabilities and for professionals to carry out the interventions. The aim of this study was to investigate the professionals' expectations regarding the project and their clients' possibilities for participating, and to investigate the professionals' experiences of the project after its completion. Focus group data with a total of 30 professionals participating were collected. A qualitative content analysis revealed four categories of the professionals' expectations before entering the project: "Clients' own possibilities and limitations for their development and independence", "Professionals' possibilities for supporting the clients", "Societal prerequisites", and "Expectations of a new way of working". Furthermore, the analysis regarding professionals' experiences after working with the project revealed three categories: "Adopting the challenges", "Having ways of working that function - prerequisites and possibilities", and "Meeting the future - an ambition to continue". Working in the Culture and Health project together with the clients in group-based activities was perceived as beneficial, although challenges arose. When implementing cultural activities, support from stakeholder organisations is needed. © 2017 Australian College of Mental Health Nurses Inc.

    Professionalism is now recognized as a core competency for graduate medical education and maintenance of certification. However, few models exist in plastic surgery that define, teach, and assess professionalism as a competency. The purpose of this project was to evaluate the effectiveness of a professionalism curriculum in an academic plastic surgery practice. We created and conducted a 6-wk, 12-h course for health care professionals in plastic surgery (faculty, residents, nurses, medical students). Teaching methods included didactic lectures, journal club, small group discussions, and book review. Topics included: (1) Professionalism in Our Culture, (2) Leadership Styles, (3) Modeling Professional Behavior, (4) Leading Your Team, (5) Managing Oneself, and (6) Leading While You Work. Using Kirkpatrick methodology to assess perception of the course (level 1 data), learning of the material (level 2 data), effect on behavior (level 3 data), and impact on the organization (level 4 data), we compiled participant questionnaires, scores from pre- and post-tests, and such metrics as incidence of sentinel events (defined as infractions requiring involvement by senior administrators), number of patient complaints reported to Patient Relations, and patient satisfaction (Press Ganey surveys), for the 6 mo before and after the course. Thirty health care professionals participated in a 6-wk course, designed to improve professionalism in plastic surgery. Level 1 data: Although only 56.5% of respondents felt that the course was a "good use of my time," 73.9% agreed that the course "will help me become a better professional" and 82.6% "would recommend the course to others." Level 2 data: Post-test scores increased from 48% to 70% (P teaching, and influencing professionalism in plastic surgery are very valuable and should be pursued by educators to help satisfy Graduate Medical Education/Maintenance of Certification requirements and to improve the performance of the organization

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

    This study aims to determine whether participation in the Nursing Leadership Perspectives Program (NLPP) at Mayo Clinic in Rochester, Minnesota, produced a change in leadership skills, increased professional activities, leadership promotion, and retention rates of participants. The NLPP is an educational program designed to enhance leadership skills and promote professionalism of registered nurses. The 6-month program provides participants with theoretical knowledge, core competencies, and opportunities to practice application of leadership skills. Outcome metrics were collected from registered nurses who completed the program (n = 15). Data analysis included descriptive and nonparametric methods. Participants reported statistically significant changes in their leadership skills after participation in the program (P = .007) on the Leadership Practices Inventory. Changes in professional behavior were also statistically significant as rated by the Nursing Activity Scale (P = .001). Participants demonstrated a change in leadership skills and professional behavior following the program.

    Full Text Available The article reviews teachers' attitudes towards the teaching profession which can be expressed both in professional commitment and in professional marginalism. The dominance of professional marginalism could affect destructively the students as well as the teacher’s personality, hence the issues related to the content of personal position of a marginal and the rate of marginalism among teachers. It was suggested that marginalism could be revealed in the study of professional commitment. The study involved 81 teachers of Sverdlovsk secondary schools aged 21—60 years with work experience ranging from 1 month to 39 years. The Professional Commitment Questionnaire was used as the study technique. The results showed that negative emotional attitude towards the profession and reluctance to leave the profession were grouped as a separate factor. The dispersion factor was 12,5%. The factor loadings ranged from 0.42 to 0.84. The study proved that professional marginalism in teachers includes dissatisfaction with work, feelings of resentment against profession and an unwillingness to leave the profession.

    The most important lessons for the physician to learn in regard to his professional liability insurance coverage are the following:1. The physician should carefully read his professional liability policy and should secure the educated aid of his attorney and his insurance broker, if they are conversant with this field.2. He should particularly read the definition of coverage and carefully survey the exclusion clauses which may deny him coverage under certain circumstances.3. If the physician is in partnership or in a group, he should be certain that he has contingent partnership coverage.4. The physician should accept coverage only from an insurance carrier of sufficient size and stability that he can be sure his coverage will be guaranteed for "latent liability" claims as the years go along-certainly for his lifetime.5. The insurance carrier offering the professional liability policy should be prepared to offer coverages up to at least $100,000/$300,000.6. The physician should be assured that the insurance carrier has claims-handling personnel and legal counsel who are experienced and expert in the professional liability field and who are locally available for service.7. The physician is best protected by a local or state group program, next best by a national group program, and last, by individual coverage.8. The physician should look with suspicion on a cancellation clause in which his policy may be summarily cancelled on brief notice.9. The physician should not buy professional liability insurance on the basis of price alone; adequacy of coverage and service and a good insurance company for his protection should be the deciding factors.

    Inadequate volume control may be a main contributor to poor survival and high mortality in hemodialysis patients. Bioimpedance measurement has the potential to improve fluid management, but several dialysis centers lack an agreed fluid management policy, and the method has not yet been implemented. Our aim was to identify renal care professionals' perceived barriers and facilitators for use of bioimpedance in clinical practice. Qualitative data were collected through four focus group interviews with 24 renal care professionals: dieticians, nephrologists and nurses, recruited voluntarily from a nation-wide selection of hemodialysis centers, having access to a bioimpedance-device. The participants were connected to each other and a moderator via equipment for telemedicine and the sessions were recorded. The interviews were semi-structured, focusing on the participants' perceptions of use of bioimpedance in clinical practice. Thematic content analysis was performed in consecutive steps, and data were extracted by employing an inductive, interactive, comparative process. Several barriers and facilitators to the use of bioimpedance in clinical practice were identified, and a multilevel approach to examining barriers and incentives for change was found to be applicable to the ideas and categories that arose from the data. The determinants were categorized on five levels, and the different themes of the levels illustrated with quotations from the focus groups participants. Determinants for use of bioimpedance were identified on five levels: 1) the innovation itself, 2) the individual professional, 3) the patient, 4) the social context and 5) the organizational context. Barriers were identified in the areas of credibility, awareness, knowledge, self-efficacy, care processes, organizational structures and regulations. Facilitators were identified in the areas of the innovation's attractiveness, advantages in practice, and collaboration. Motivation, team processes and

    Radiotherapy (RT) units are high-tech nursing environments. In Sweden, RT registered nurses (RNs) provide and manage RT in close collaboration with other professional groups, as well as providing nursing care for patients with cancer. Communication demands on these RNs are thus particularly complex. In this study, we aimed to better understand problems, strengths and change needs related to professional communication with and within the RT department, as a basis for developing a situation-specific intervention. Focus groups discussions (FGDs) were conducted with different professional (RNs, assistant nurses, physicians, engineers and physicists) and user stakeholders. Transcripts of the FGDs were inductively analyzed by a team of researchers, to generate clinically relevant and useful data. These findings give insight into RT safety climate and are presented under three major headings: Conceptualization of professional domains; Organization and leadership issues; and Communication forms, strategies and processes. The impact of existing hierarchies, including how they are conceptualized and acted out in practice, was noted throughout these data. Despite other differences, participating professionals agreed about communication problems related to RT, i.e. a lack of systems and processes for information transfer, unclear role differentiation, a sense of mutual disrespect, and ad hoc communication taking place 'on the fly'. While all professional groups recognized extensive communication problems, none acknowledged the potential negative effects on patient safety or care described in the FGD with patient representatives. While RNs often initially denied the existence of a hierarchy, they placed themselves on a hierarchy in their descriptions, describing their own role as passive, with a sense of powerlessness. Potential safety hazards described in the FGDs include not reporting medical errors and silently ignoring or actively opposing new guidelines and regulations

    Full Text Available Gingipain cysteine proteases are considered key virulence factors of Porphyromonas gingivalis. They significantly influence antibacterial and homeostatic functions of macrophages, neutrophils, the complement system, and cytokine networks. Recent data indicate the role of P. gingivalis in T cell differentiation; however, the involvement of gingipains in this process remains elusive. Therefore, the aim of this study was to investigate the contribution of danger signals triggered by the gingipains on the generation of Th17 cells, which play a key role in protection against bacterial diseases but may cause chronic inflammation and bone resorption. To this end we compared the effects of the wild-type strain of P. gingivalis (W83 with its isogenic mutant devoid of gingipain activity (ΔKΔRAB, and bacterial cells pretreated with a highly-specific inhibitor of gingipains activity (KYTs. Antigen presenting cells (APCs, both professional (dendritic cells, and non-professional (gingival keratinocytes, exposed to viable bacteria expressed high amounts of cytokines (IL-6, IL-21, IL-23. These cytokines are reported to either stimulate or balance the Th17-dependent immune response. Surprisingly, cells infected with P. gingivalis devoid of gingipain activity showed increased levels of all tested cytokines compared to bacteria with fully active enzymes. The effect was dependent on both the reduction of cytokine proteolysis and the lack of cross-talk with other bacterial virulence factors, including LPS and fimbriae that induce de novo synthesis of cytokines. The profile of lymphocyte T differentiation from naive T cells showed enhanced generation of Th17 in response to bacteria with inactive gingipains. Moreover, we found that gingipain-dependent induction of Th17 cells was highly specific, since other T cell-subsets remained unchanged. Finally, inhibition of IL-6 signaling in dendritic cells led to a significant depletion of the Th17 population. Cumulatively

Therefore, the aim of this study was to investigate the contribution of danger signals triggered by the gingipains on the generation of Th17 cells, which play a key role in protection against bacterial diseases but may cause chronic inflammation and bone resorption. To this end we compared the effects of the wild-type strain of P. gingivalis (W83) with its isogenic mutant devoid of gingipain activity (ΔKΔRAB), and bacterial cells pretreated with a highly-specific inhibitor of gingipains activity (KYTs). Antigen presenting cells (APCs), both professional (dendritic cells), and non-professional (gingival keratinocytes), exposed to viable bacteria expressed high amounts of cytokines (IL-6, IL-21, IL-23). These cytokines are reported to either stimulate or balance the Th17-dependent immune response. Surprisingly, cells infected with P. gingivalis devoid of gingipain activity showed increased levels of all tested cytokines compared to bacteria with fully active enzymes. The effect was dependent on both the reduction of cytokine proteolysis and the lack of cross-talk with other bacterial virulence factors, including LPS and fimbriae that induce de novo synthesis of cytokines. The profile of lymphocyte T differentiation from naive T cells showed enhanced generation of Th17 in response to bacteria with inactive gingipains. Moreover, we found that gingipain-dependent induction of Th17 cells was highly specific, since other T cell-subsets remained unchanged. Finally, inhibition of IL-6 signaling in dendritic cells led to a significant depletion of the Th17 population. Cumulatively, this study

    Background: Cervical cancer is the third most common cancer in women throughout the world. The human papillomavirus (HPV) E6 viral protein plays an essential role in proteasomal degradation of the cancer suppressant protein p53. As a result, p53 negative regulation and apoptosis relevant activities are abrogated, facilitating development of cervical cancer. Methods: A mathematical model of E6-p53 interactions was developed using mathematical laws. In-silico simulations were carried out on CellDesigner and as a test case the small molecule drug RITA was considered for its ability to rescue the functions of tumor suppressor p53 by inhibiting E6 mediated proteasomal degradation. Results: Using a computational model we scrutinized how p53 responds to RITA, and chemical reactions of this small molecule drug were incorporated to perceive the full effects. The evolved strategy allowed the p53 response and rescue of its tumor suppressor function to be delineated, RITA being found to block p53 interactions with E6 associated proteins. Conclusion: We could develop a model of E6-p53 interactions with incorporation of actions of the small molecule drug RITA. Suppression of E6 associated proteins by RITA induces accumulation of tumor suppressant p53. Using CellDesigner to encode the model ensured that it can be easily modified and extended as more data become available. This strategy should play an effective role in the development of therapies against cancer. Creative Commons Attribution License

    We have determined the identity of the orphan G-protein coupled receptor cDNA, 6H1, present in activated chicken T cells, as a subtype of P2Y purinoceptor. This identification is based on first on the degree of sequence identity shared with recently cloned members of the P2Y receptor family and second on the pharmacological profile. Upon transient expression in COS-7 cells the 6H1 receptor bound the radiolabel [35S]dATP alpha S specifically and with high affinity (Kd, 10 nM). This specific binding could be competitively displaced by a range of ligands active at P2 purinoceptors, with ATP being the most active (K (i)), 116 nM). Such competition studies have established the following rank order of activity: ATP ADP 2-methylthioATP alpha, beta-methylene ATP, UTP, thus confirming 6H1 as a member of the growing family of P2Y purinoceptors. As the fifth receptor of this type to be identified we suggest that it be named P2Y5.

    Continuing education is one of the means by which professionals maintain and increase their level of competence. However, the relationship between continuing education and the professional's sense of personal competence and other practice-related variables remains unclear. This study examined practicing psychologists' continuing education activities and how these relate to feelings of perceived competence, professional value, and professional support. Psychologists (n = 418) licensed to practice in Quebec were surveyed by pencil-and-paper mail-in survey concerning their continuing education activities, as well as their perceptions of their competence in practice, and their feelings of being professionally valued and professionally supported. Results indicated that feelings of competence in practice were related to professional reading, taking courses/workshops, years being licensed, and attending psychology conferences/conventions. Feelings of professional value were related to age and participating in psychology networking groups, and feelings of professional support were related to participating in case discussion groups, supervision groups, and psychology networking groups. The results showcase the complexity of professional development. Although relationships were found between continuing education activities and the 3 factors of interest, these relationships were moderate. Findings are discussed in the context of their value to individual psychologists, as well as to psychology licensing and regulatory boards, such as promoting participation in those activities related to feelings of competence and support.

    The elastic scattering p( 6 He, 6 He)p and charge exchange reaction p( 6 He, 6 Li)n have been measured in reverse kinematics with a secondary 6 He beam. The angular distributions for these reactions were obtained. In the case of the charge exchange reaction, the ratio of the cross section for the Gamow-Teller transition to the ground state, and for the Fermi transition to the isobaric analog state is a measure of the relative strength of the two components of the exchange interaction. This ratio is found compatible with existing systematics for stable T=1 nuclei, and no clear signature of a halo structure was found in the present data. (author)

    The objective of our study was to evaluate the outcomes of a women in radiology (WIR) group during the first 6 years of its existence, including members' satisfaction, activities, and differences based on seniority. An anonymous questionnaire was distributed to group members. Survey questions were related to the usefulness of sessions, mentoring, professional opportunities, and camaraderie. Comparisons were made on the basis of training status and seniority. Continuous variables were compared using means, t tests, and correlations, and categoric variables were compared using counts, percentages, and chi-square tests or Mantel-Haenszel tests. Surveys were sent to 61 women, including trainees and faculty; the response rate was 49% (38% of trainees and 53% of faculty). Overall satisfaction score for WIR sessions was high (mean summary score, 1.42 ± 0.37 [SD], with 1 meaning very satisfied and 4 meaning very unsatisfied). Trainees and junior faculty were more likely than senior faculty to report expanded internal networking opportunities (94% vs 69%; p = 0.07), to have gained a mentor (67% vs 8%; p = 0.001), and to have increased research involvement (33% vs 0%; p = 0.02). Both groups were equally likely to have become mentors. Almost all respondents (93%) reported increased camaraderie among women in the department. A WIR group can provide career development tools for its members. In this study, trainees and junior faculty reported increased networking and research involvement and gaining a mentor but were equally likely as senior faculty to have become mentors. Most members reported increased camaraderie among women in the department. A WIR group may help to accelerate professional development among trainees and junior faculty, thereby contributing to a more diverse and enabled workforce.

    Full Text Available Introduction. Identification of victims of domestic violence among the women using the healthcare is not sufficient. Objective. The aim of this study is to identify the barriers that prevent health care professionals in identifying domestic violence more often. Method. A questionnaire was distributed to health workers in the Health center of Kraljevo, by e-mail. Results. The study comprised 136 health care workers, 73.3% female and 26.7% male. 70.6% were doctors and 29.4% technicians. The mean age of respondents was 38.93 ± 7.7, (range 31-50, with the average 11.36 ± 7.74 years of service. The social barriers were significantly more present among female health workers (p=0.037. The most frequent answer is the lack of guidelines. This answer is significantly in correlation with professional qualification (p=0.002. The prominent institutional barriers are overwork (53.7%, lack of information about the procedures (significantly present among doctors, p=0.003, and the fear for their own safety (46.3%. Barriers associated to the health care workers themselves have the least number of responses, with limited time as the most important, followed by lack of training (44.9% and lack of knowledge, that is significantly related to gender (p=0.002 and to qualifications (p=0.009. Women expect more authority in their work, p=0.035. Among the 4 groups of barriers, the majority of answers is related to the victims of violence themselves (43.9%, statistically more significant among doctors, p=0.004, predominantly responding that victims hide the violent behavior of their partners (65.4%. Conclusion. Provide continuous education about domestic violence and evaluation of knowledge, encourage the victims to trust the health system, raise awareness about the judgment of violence, and skillfully inform the women of resources in the community.

    Full Text Available Certain authors describe some professions in the healthcare industry as the more susceptible ones to developing a burnout syndrome, while others suggest psychosocial aspects of the workplace as the primary cause in its creation, but not the aspects of the job itself. The main objective of the research was to investigate which specific factors were associated with the burnout syndrome among professionals working in pharmaceutical manufacturing industry and marketing. The study was conducted in June of 2016 as a cross-sectional study and it included 75 university educated professionals from the area of pharmaceutical industry and marketing employed in several local as well as internationally renowned pharmaceutical companies located in Belgrade. The participants were surveyed anonymously. The instruments used in the study were: a general socio-demographic questionnaire, an assertiveness self-evaluation questionnaire and the Maslach Burnout Inventory. An analysis of the responses in the burnout syndrome self-evaluation questionnaires showed that the highest level of burnout was expressed through reduced personal accomplishment (53%. The average assertiveness scores were the lowest in the individuals who demonstrated the highest level of emotional exhaustion (p=0.003, depersonalization (p=0.004, and the highest inefficiency on professional accomplishment scale (p=0.001. A statistically significant difference was observed in frequency and extent of emotional exhaustion with respect to respondents' gender (x2=10.779; p<0.05, as well as the line of business (x2=6.493; p<0.05. Levels of depersonalization are influenced by: line of work (x2=5.393; p<0.05, age (p=0.004, total years of service (p=0.009 and years of service in the profession (p=0.006. A sense of reduced personal accomplishment is influenced by a respondents' profession (x2=10.922; p<0.05 and line of business (x2=7.283; p<0.05.

    Today's physicians must demonstrate both professionalism and leadership skills in order to succeed in largely team-based healthcare environments. The purpose of this study was to determine if professionalism attributes, leadership style, and leadership style adaptability are associated with academic performance among first-year students early in their medical curriculum. Students were divided into 4-member dissection groups for the duration of the Gross and Developmental Anatomy course. Leadership responsibility was randomly assigned to a team member on a rotating basis every 5 weeks. After each 5-week block, student performance was measured by written and practical examinations, and each student assessed their leader's or their own professionalism attributes and leadership style using validated survey instruments. Most students demonstrated either a "selling" only (57%) or "participating" only (30%) leadership style with low to moderate leadership adaptability. "Participating" and "delegating" leadership styles have the highest average group written exam scores (89.4%, P leadership styles and aspects of professionalism are associated with written and practical examination scores in the Gross and Developmental Anatomy course. Furthermore, it demonstrates that first-year medical students are in need of leadership skill development.

    2010-01-01

    Purpose: Updating professional knowledge is a central tenet of Continuing Professional Development (CPD) and professional reading is a common method health practitioners use to update their professional knowledge. This paper reports the level of professional reading by Medical Radiation Science (MRS) practitioners in Australia and examines organisational support for professional reading. Materials and Methods: Survey design was used to collect data from MRS practitioners. A questionnaire was sent to 1142 Australian practitioners, which allowed self-report data to be collected on the length of time practitioners engage in professional reading and the time workplaces allocate to practitioners for professional reading. Results: Of the 362 MRS practitioners who returned the survey, 93.9% engaged in professional reading on a weekly basis. In contrast, only 28.9% of respondents reported that their workplace allocates time for professional reading to practitioners. MRS practitioners employed in universities engaged in higher levels of reading than their colleagues employed in clinical workplaces (p < 0.01) and more university workplaces allocated time for professional reading to their employees than clinical workplaces (p < 0.01). There were no significant differences for clinical practitioners in level of reading across geographic, organisational and professional demographic factors. Significant differences in workplace allocation of time for professional reading in clinical workplaces were evident for health sector (p < 0.01); work environment (p < 0.01); geographic location (p < 0.01) and area of specialisation (p < 0.01). Conclusion: The vast majority of respondent MRS practitioners engage in professional reading to update their professional knowledge. This demonstrates an ongoing commitment at the individual practitioner level for updating professional knowledge. Updating professional knowledge is an organisational as well as an individual practitioner issue. Whilst

    2018-01-01

    Objective It is generally believed that professional drivers can manage quite severe fatigue before routine driving performance is affected. In addition, there are results indicating that professional drivers can adapt to prolonged night shifts and may be able to learn to drive without decreased performance under high levels of sleepiness. However, very little research has been conducted to compare professionals and non-professionals when controlling for time driven and time of day. Method The aim of this study was to use a driving simulator to investigate whether professional drivers are more resistant to sleep deprivation than non-professional drivers. Differences in the development of sleepiness (self-reported, physiological and behavioral) during driving was investigated in 11 young professional and 15 non-professional drivers. Results Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. In contradiction, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness. They also drove faster. The reason for the discrepancy in the relation between the different sleepiness indicators for the two groups could be due to more experience to sleepiness among the professional drivers or possibly to the faster speed, which might unconsciously have been used by the professionals to try to counteract sleepiness. Conclusion Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. However, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness, and they drove faster.

  1. Prediction of pKa values using the PM6 semiempirical method

    2016-08-01

    Full Text Available The PM6 semiempirical method and the dispersion and hydrogen bond-corrected PM6-D3H+ method are used together with the SMD and COSMO continuum solvation models to predict pKa values of pyridines, alcohols, phenols, benzoic acids, carboxylic acids, and phenols using isodesmic reactions and compared to published ab initio results. The pKa values of pyridines, alcohols, phenols, and benzoic acids considered in this study can generally be predicted with PM6 and ab initio methods to within the same overall accuracy, with average mean absolute differences (MADs of 0.6–0.7 pH units. For carboxylic acids, the accuracy (0.7–1.0 pH units is also comparable to ab initio results if a single outlier is removed. For primary, secondary, and tertiary amines the accuracy is, respectively, similar (0.5–0.6, slightly worse (0.5–1.0, and worse (1.0–2.5, provided that di- and tri-ethylamine are used as reference molecules for secondary and tertiary amines. When applied to a drug-like molecule where an empirical pKa predictor exhibits a large (4.9 pH unit error, we find that the errors for PM6-based predictions are roughly the same in magnitude but opposite in sign. As a result, most of the PM6-based methods predict the correct protonation state at physiological pH, while the empirical predictor does not. The computational cost is around 2–5 min per conformer per core processor, making PM6-based pKa prediction computationally efficient enough to be used for high-throughput screening using on the order of 100 core processors.

    2010-12-01

    Teachers are required to work with data on a daily basis to assess the effectiveness of their teaching strategies, but may not approach it as research. This paper presents a reflective discussion of how and when a professional development team used an action research project to help 12 K-6 teachers explore the effectiveness of reform based Nature of Science (NOS) teaching strategies in their classrooms. The team encouraged community development and provided “just in time” supports to scaffold the steps of the action research process for teachers. The discussion includes concerns they addressed and issues related to management and support of the professional development model. Evaluation results are shared to suggest how this approach can be improved in the future.

    The aim of the research was an analysis of the eating habits of professional volleyball players according to their sex and age. The research has been carried out on a group of 210 men players and women players at the age of 13-25, representatives of sports clubs in Ostrołeka, Myślenice, Bydgoszcz and Warszawa. The research has revealed a limited realisation of rational diets by both men and women players. The most common mistakes made by them include a smaller number of meals during the day than recommended (especially among men), taking up training on empty stomach and insufficient frequency of consumption of dairy products, fish, vegetables and fruit. The research has also revealed excessive consumption of sweets, sweet sparkling drinks and fast food (mainly among men). The examined players to some extent only apply regular strategies of rehydration of their organisms. A high percentage of them do not pay attention to supplementation of liquids after an effort or they drink a lot of liquids at one time. The most frequently chosen drinks were mineral water and isotonic drinks. Supplementation was applied by a small percentage of the players, mainly men, who most often chose vitamins, Izostar, creatine, L-carnitine and HMB.

    For many eServices, end-user trust is a crucial prerequisite for use. Within the context of Telemedicine, the role of trust has hardly ever been studied. In this study, we explored what determines trust in portals that facilitate rehabilitation therapy, both from the perspective of the patient and the healthcare professional. We held two focus groups with patients (total n = 15) and two with healthcare professionals (total n = 13) in which we discussed when trust matters, what makes up trust in a rehabilitation portal, what effect specific design cues have, and how much the participants trust the use of activity sensor data for informing treatment. Trust in a rehabilitation portal is the sum of trust in different factors. These factors and what makes up these factors differ for patients and healthcare professionals. For example, trust in technology is made up, for patients, mostly by a perceived level of control and privacy, while for healthcare professionals, a larger and different set of issues play a role, including technical reliability and a transparent data storage policy. Healthcare professionals distrust activity sensor data for informing patient treatment, as they think that sensors are unable to record the whole range of movements that patients make (e.g., walking and ironing clothes). The set of factors that affect trust in a rehabilitation portal are different from the sets that have been found for other contexts, like eCommerce. Trust in telemedicine technology should be studied as a separate subject to inform the design of reliable interventions.

    A crown-bridged calix[4]arene scaffold was investigated as lead compound for the ligation of heavy alkaline earth metals such as strontium and barium, which appear to be useful for radiopharmaceutical applications in diagnosis as well as in radiotherapy. In particular barium, due to its chemical similarities, could serve as a surrogate for radium, a metal of high radiopharmaceutical interest. The ability of p-tert-butylcalix[4]arene-1,3-crown-6 (1) in particular to chelate cations, such as group 1 and 2 metal ions or ammonium ions is well known. Also, the manifold possibilities of structural modification on the upper- and lower-rim as well as on the crown itself produce properties that may lead to a highly selective and effective chelating agent. In this work, titration experiments of the perchlorate salts of Ba2+, Sr2+ and Pb2+ with ligand 1 were performed to determine their stability constants (logK = 4.7, 4.3, and 3.3, respectively) by 1H NMR measurements in acetonitrile-d3.

    The physical and psychological demands of playing a musical instrument are likely to be affected by age-related decline in function, including physical, cognitive, psychological, and organ-related changes. However, the complex neurophysiological demands of playing a musical instrument may delay many normal aging-related changes. This study compared professional classical musicians of different ages, using a range of physical and psychological measures, to discover how increasing age might affect work performance and to identify possible risk and protective factors for physical and psychological health as the musicians age. 377 professional orchestral musicians from eight Australian orchestras (70% response rate), ages 18 to 68 yrs (mean 42.1). Multiple standardized physical and psychological tools were used to evaluate the impact of age on a range of physical and mental health variables. Age was not statistically associated with frequency or severity of performance-related musculoskeletal disorders, ratings of perceived exertion, QuickDASH scores, use of beta-blockers, workplace satisfaction, and most psychological tests. Differences were observed on SPIN (social anxiety) scores, with lowest scores in the oldest age group (10.66 in 55+ yrs vs 17.83 in 18-30 yrs, p=0.016). Older musicians had higher BMIs and fewer practice sessions per day than younger musicians and also were more likely to consume alcohol on 5+ days/wk (44% vs 9%, p=0.003). Advancing age does not appear to exert undue negative impacts on physical and psychological health or performance capacity of professional orchestral musicians. However, dwindling numbers in the older age groups may suggest a "survivor" effect, whereby those who develop significant age-related decrements may cease professional performance at earlier ages. Longitudinal studies on the professional trajectories of professional orchestral musicians are needed to explore this question further.

    The stability of S-(purin-6-yl)-L-cysteine (SPC), a kidney-selective prodrug of 6-mercaptopurine and a putative metabolite of 6-chloropurine, was investigated under various pH and temperature conditions. At room temperature, the half-life (t 1/2) of SPC at either highly acidic (pH 3.6) or basic conditions (pH 9.6) was longer than at neutral or slightly acidic or basic conditions (pH 5.7-8.75). The primary degradation product, N-(purin-6-yl)-L-cysteine (NPC), was isolated using Sephadex LH-20 chromatography and characterized by 1H NMR and FAB/MS after derivatization with 2-iodoacetic acid. These results reveal novel stability requirements and implicate the cysteinyl amino group and the purinyl N-1 nitrogen in the mechanism of SPC rearrangement to NPC. Further evidence for this hypothesis was provided by the findings that the stability of SPC in phosphate buffer (pH 7.4) at 37 degrees C was similar to that of S-(guanin-6-yl)-L-cysteine, whereas S-(purin-6-yl)-N-acetyl-L-cysteine and S-(purin-6-yl)glutathione which have their cysteine amino groups blocked were much more stable than SPC. S-(Purin-6-yl)-L-homocysteine (SPHC) was also more stable than SPC, possibly because the formation of a 6-membered ring transition state as would be expected with SPHC is kinetically less favored than the formation of a 5-membered ring transition state as would be expected with SPC. These results may explain previous in vivo metabolism results of SPC and its analogs and may contribute to a better understanding of stability of structurally related cysteine S-conjugates.

    Peroxidases are essential enzymes in biodegradation of lignin and lignite which have been investigated intensively in the white-rot fungi. This is the first report of purification and characterization of lignin peroxidase from Penicillium sp. P6 as lignite degradation fungus. The results indicated that the lignin peroxidase of Penicillium decumbens P6 had physical and chemical properties and a N-terminal amino acid sequence different from the lignin peroxidases of white-rot fungi. The lignin peroxidase was isolated from a liquid culture of P. decumbens P6. This enzyme had a molecular weight of 46.3 KDa in SDS-PAGE and exhibited greater activity, temperature stability and wider pH range than those previously reported. The isolation procedure involved (NH{sub 4}){sub 2}SO{sub 4} precipitation, ion-exchange chromatography on DEAE-cellulose and CM-cellulose, gel filtration on Sephadex G-100, and non-denaturing, discontinuous polyacrylamide gel electrophoresis. The K{sub m} and V{sub max} values of this enzyme using veratryl alcohol as substrate were 0.565 mmol L{sup -1} and 0.088 mmol (mg protein){sup -1} min{sup -1} respectively. The optimum pH of P6 lignin peroxidase was 4.0, and 70.6% of the relative activity was remained at pH 9.0. The optimum temperature of the enzyme was 45{sup o}C.

    Use of polymerase chain reaction helped to establish that the most frequent among naphthalene utilizing bacteria, isolated on the territory of Belarus, are Nah-plasmids of IncP-9 incompatibility group and those with indefinite systematic belonging. With the help of classical test of incompatibility, restriction and sequence analyses three new subgroups within the IncP-9 group were discovered (zeta, eta and IncP-9-like replicons). Conducting of restriction analysis for amplification products of nahG and nahAc genes allowed us to reveal, in addition to known sequences of stated determinants, two new types of nahG gene. Restriction analysis performed on amplification products of 16S RNA genes (ARDRA method) showed that native hosts of Nah-plasmids of IncP-9 group are not only fluorescent bacteria from genus Pseudomonas (P. fluorescens, P. putida, P. aeruginosa, P. species), but also non-fluorescent bacteria with indefinite specific belonging.

    p,pN-Dichlorodiphenyl sulfone is used as a starting material in the production of polysulfones and polyethersulfones and as a component in reactive dyes in the textile industry; it is also a by-product of pesticide production. p,pN-Dichlorodiphenyl sulfone was nominated for study by the National Cancer Institute because of its history of high production and use, the prospect of increased production and use, and the absence of adequate toxicity testing. Male and female F344/N rats and B6C3F1 mice were exposed top,pN-dichlorodiphenyl sulfone (greater than 99% pure)in feed for 14 weeks or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium,cultured Chinese hamster ovary cells, and mouse bone marrow. 14-WEEK STUDY IN RATS: Groups of 10 male and 10 female F344/N rats were fed diets containing 0, 30, 100, 300, 1,000, or 3,000 ppm p,pN-dichlorodiphenyl sulfone (equivalent to average daily doses of approximately 2, 6, 19, 65, or 200 mgp,pN-dichlorodiphenyl sulfone/kg body weight) for 14 weeks. All rats survived until the end of the study. Mean body weights of groups exposed to 300 ppm or greater were significantly less than those of the controls. Liver weights of groups exposed to 100 ppm or greater and kidney weights of 1,000 and 3,000 ppm male rats were significantly greater than those of the controls. Centrilobular hepatocyte hypertrophy of the liver was observed in most male rats exposed to 100 ppm or greater and in all female rats exposed to 300 ppm or greater, and the severities were increased in 300 ppm males and 1,000 and 3,000 ppm males and females. The incidences of nephropathy in 1,000 and 3,000 ppm female rats were significantly increased. Dose-related increases in severity of nephropathy were observed in male rats. 14-WEEK STUDY IN MICE: Groups of 10 male and 10 female B6C3F1 mice were fed diets containing 0, 30, 100, 300, 1,000, or 3,000 ppm p,pN-dichlorodiphenyl sulfone (equivalent to average daily doses of approximately 3.5, 15, 50

    Primary: To determine the differences, by occupational category and province, in the knowledge and attitudes of health professionals on the Living Wills Document (LWD) in 4 Andalusian provinces: Cordoba, Jaen, Cadiz, and Granada. Secondary: To determine the number of documents prepared in these areas and the number consulted in terminal situations. Descriptive observational multicenter study, with 17 health areas in 4 Andalusian provinces. Family doctors, nurses and social workers of the areas studied (n=340). Interventions Validated self-administered questionnaire about advance directives. Descriptive and bivariate (×2) analysis of data was performed. Mean age 46±8.8 years, 53.2% women. Physicians 56.1%, nurses 41.1%, social workers 2.6%. The mean score (0-10) of their knowledge was 5.42±2.41, with 78.4% believing that LWD are regulated in Andalusia (provinces differences, P=.001). More than one-third (36.7%) had read the document (differences by occupation, P=.001). The mean score on the advantage of preparing a LWD for the patient was 8.27±2.16 (significant differences between provinces P=.02). Mean score about the practitioner would respect the wishes of a patient in a LWD was 9.14±1.64 (significant difference between provinces P=.03). The mean score of the question about expressing the desires of the professional on preparing their LWD in the following year was 4.85±3.74 (P=.02). There are different behaviors between professions on reading the LWD. There are differences between provinces in the following aspects: whether the documents are regulated, whether the professionals prepare the LWD, and whether the professionals respects the provisions of the LWD.

    Tobacco use adversely affects oral health. Clinical guidelines recommend that oral health professionals promote tobacco abstinence and provide patients who use tobacco with brief tobacco use cessation counselling. Research shows that these guidelines are seldom implemented successfully. This study aimed to evaluate two interventions to enhance tobacco use prevention and cessation (TUPAC) counselling among oral health professionals in Finland. We used a cluster-randomized community trial to test educational and fee-for-service interventions in enhancing TUPAC counselling among a sample of dentists (n=73) and dental hygienists (n=22) in Finland. Educational intervention consisted of 1 day of training, including lectures, interactive sessions, multimedia demonstrations and a role play session with standard patient cases. Fee-for-service intervention consisted of monetary compensation for providing tobacco use prevention or cessation counselling. TUPAC counselling procedures provided were reported and measured using an electronic dental records system. In data analysis, intent-to-treat principles were followed at both individual and cluster levels. Descriptive analysis included chi-square and t-tests. A general linear model for repeated measures was used to compare the outcome measures by intervention group. Of 95 providers, 73 participated (76.8%). In preventive counselling, there was no statistically significant time effect or group-by-time interaction. In cessation counselling, statistically significant group-by-time interaction was found after a 6-month follow-up (F=2.31; P=0.007), indicating that counselling activity increased significantly in intervention groups. On average, dental hygienists showed greater activity in tobacco prevention (F=12.13; P=0.001) and cessation counselling (F=30.19; PTUPAC counselling performance. Other approaches than monetary incentives may be needed to enhance the effectiveness of educational intervention. Further studies with focus

    Elevated titers of antibodies against oxidized low-density lipoproteins-cholesterol (ox-LDL-Ab) have been reported among professional athletes, paradoxically reflecting an increased risk of developing atherogenic and/or cardiovascular events. This study aimed to determine titers of ox-LDL-Ab in a group of Cameroonian professional soccer players, and evaluate their evolution during part of a competition season as well as the plasmatic antioxidant status to find out if this latter correlates with ox-LDL-Ab . We conducted a descriptive cohort study in 2012 including 18 healthy male soccer players. Three samplings were performed in March (T1), May (T2), and July 2012 (T3) to assess the lipid profile, titers of ox-LDL-Ab, and plasmatic concentrations of four antioxidants: the ferric reducing antioxidant power (FRAP), reduced glutathione (GSH), superoxide dismutase (SOD), and uric acid. Ages ranged from 16 to 28 years with a median (interquartile range) of 19.5 (19-23) years. Total cholesterol, high-density lipoproteins-cholesterol (HDL-C), low-density lipoproteins-cholesterol (LDL-C) and triglycerides varied within normal ranges throughout the three samplings. While total cholesterol and LDL-C titers increased significantly (p = 0.003 and p = 0.006, respectively), triglycerides and HDL-C values varied non-significantly throughout the measurements (p = 0.061 and p = 0.192, respectively). The median ox-LDL-Ab titers were respectively: 653.3 (468.2-838.8) mIU/ml at T1, 777.7 (553.7-1150.7) mIU/ml at T2, and 1037.7 (901.7-1481.5) mIU/ml at T3. Overall, ox-LDL-Ab titers increased significantly from T1 to T3 (p = 0.006). Concomitantly, uric acid and FRAP concentrations decreased significantly (p = 0.001 and p = 0.003, respectively); on the contrary, GSH and SOD values increased, but insignificantly (p = 0.115 and p = 0.110, respectively). There was a positive and significant correlation between ox-LDL-Ab and HDL-C (ρ = 0.519, p = 0.027), and between ox

    group that was randomized to the game had statistically higher scores on the knowledge test (P = 0.02). The second study compared game-based learning ("Snakes and Ladders" board game) with traditional case-based learning of stroke prevention and management. The effect on knowledge was not statistically different between the two groups immediately and 3 months after the intervention. The level of reported enjoyment was higher in the game-based group. The findings of this systematic review neither confirm nor refute the utility of games as a teaching strategy for health professionals. There is a need for additional high-quality research to explore the impact of educational games on patient and performance outcomes.

    Full Text Available Abstract Background Radiotherapy (RT units are high-tech nursing environments. In Sweden, RT registered nurses (RNs provide and manage RT in close collaboration with other professional groups, as well as providing nursing care for patients with cancer. Communication demands on these RNs are thus particularly complex. In this study, we aimed to better understand problems, strengths and change needs related to professional communication with and within the RT department, as a basis for developing a situation-specific intervention. Methods Focus groups discussions (FGDs were conducted with different professional (RNs, assistant nurses, physicians, engineers and physicists and user stakeholders. Transcripts of the FGDs were inductively analyzed by a team of researchers, to generate clinically relevant and useful data. Results These findings give insight into RT safety climate and are presented under three major headings: Conceptualization of professional domains; Organization and leadership issues; and Communication forms, strategies and processes. The impact of existing hierarchies, including how they are conceptualized and acted out in practice, was noted throughout these data. Despite other differences, participating professionals agreed about communication problems related to RT, i.e. a lack of systems and processes for information transfer, unclear role differentiation, a sense of mutual disrespect, and ad hoc communication taking place ‘on the fly’. While all professional groups recognized extensive communication problems, none acknowledged the potential negative effects on patient safety or care described in the FGD with patient representatives. While RNs often initially denied the existence of a hierarchy, they placed themselves on a hierarchy in their descriptions, describing their own role as passive, with a sense of powerlessness. Potential safety hazards described in the FGDs include not reporting medical errors and silently ignoring

    To characterise some of the environmental factors that are sensitive to cultural influence, and are involved in the development of medical empathy in Spanish and Latin American physicians-in-training. Cross-sectional study using questionnaires. Primary care and specialized medicine centres of the Healthcare System of La Rioja, Logroño, Spain. Physicians-in-training MAIN MEASUREMENTS: : Empathy was measured using the Jefferson Scale of Physician Empathy, version for healthcare professionals (JSE-HP). Socio-demographic, academic, and professional background information was collected. A total of 104 residents (67 from Spain and 32 from Latin America) answered and returned the questionnairess. The JSE-HP showed adequate psychometric properties. The empathy mean score of Spanish group was higher than that of the Latin American group (P=.01). Differences in the development of empathy were associated with: the development of professional models (P<.001), the positive encounter with other professionals (P=.001), and with a continuing medical education (P=.008). Some factors involved in the development of empathy that are sensitive to cultural influence have been characterised. The development of future research areas is suggested.

    Full Text Available The purpose of this study was to examine whether insulin-like growth factor (IGF-1 and Akt/mTOR/p70S6K pathway activity is altered by chronic eccentric exercise in rat medial gastrocnemius muscle. Male Wistar rats (n = 24 were randomly assigned to 1 of the 2 groups: eccentric exercise (ECC group or sham-operated control (CON group. Rats in the ECC group were trained every second day for 10 days (5 sessions in total or 20 days (10 sessions in total. After either 5 or 10 exercise sessions, muscle specimens were dissected and weighed. The mRNA expression of IGF-1 and its variant, mechano growth factor (MGF, was evaluated using real time reverse transcriptase-polymerase chain reaction (RT-PCR. Tissue concentrations of Akt (P, mTOR (P, and p70S6K (P were measured by using western blot analysis. The medial gastrocnemius muscle mass of the ECC group did not show any significant difference after 5 exercise sessions, whereas the muscle mass increased significantly after 10 exercise sessions with a concomitant increase in the cross-sectional area of muscle fibers (p < 0.05. The expression of IGF-1 mRNA and the tissue concentrations of Akt (P and p70S6K (P after 10 exercise sessions was significantly higher than those of the age-matched controls and the rats that received 5 exercise sessions. The expression of MGF mRNA in both ECC5S and ECC10S were significantly higher than that in each period-matched control (p < 0.01. The tissue concentration of mTOR (P after 10 sessions showed a significant increase when compared with period-matched controls (p < 0.01. These results suggest that activation of the IGF-1/Akt/mTOR/p70S6K signaling pathway becomes dominant in the later phase of chronic exercise, when significant muscular hypertrophy is observed

  1. GRIM-19 disrupts E6/E6AP complex to rescue p53 and induce apoptosis in cervical cancers.

    Directory of Open Access Journals (Sweden)

    Ying Zhou

    Full Text Available BACKGROUND: Our previous studies showed a down-regulation of GRIM-19 in primary human cervical cancers, and restoration of GRIM-19 induced tumor regression. The induction of tumor suppressor protein p53 ubiquitination and degradation by E6 oncoportein of high risk-HPV through forming a stable complex with E6AP is considered as a critical mechanism for cervical tumor development. The aims of this study were to determine the potential role of GRIM-19 in rescuing p53 protein and inducing cervical cancer cell apoptosis. METHODOLOGY/PRINCIPAL FINDINGS: The protein levels of GRIM-19 and p53 were detected in normal cervical tissues from 45 patients who underwent hysterectomy for reasons other than neoplasias of either the cervix or endometrium, and cervical cancer tissues from 60 patients with non-metastatic squamous epithelial carcinomas. Coimmunoprecipitation and GST pull-down assay were performed to examine the interaction of GRIM-19 with 18E6 and E6AP in vivo and in vitro respectively. The competition of 18E6 with E6AP in binding GRIM-19 by performing competition pull-down assays was designed to examine the disruption of E6/E6AP complex by GRIM-19. The augment of E6AP ubiquitination by GRIM-19 was detected in vivo and in vitro ubiquitination assay. The effects of GRIM-19-dependent p53 accumulation on cell proliferation, cell cycle, apoptosis were explored by MTT, flow cytometry and transmission electron microscopy respectively. The tumor suppression was detected by xenograft mouse model. CONCLUSION/SIGNIFICANCE: The levels of GRIM-19 and p53 were concurrently down regulated in cervical cancers. The restoration of GRIM-19 can induce ubiquitination and degradation of E6AP, and disrupt the E6/E6AP complex through the interaction of N-terminus of GRIM-19 with both E6 and E6AP, which protected p53 from degradation and promoted cell apoptosis. Tumor xenograft studies also revealed the suppression of p53 degradation in presence of GRIM-19. These data

    Myelodysplastic syndromes (MDS), acute erythroleukemia (FAB M6), and acute megakaryocytic leukemia (FAB M7) have overlapping features. Children without Down syndrome or acute promyelocytic leukemia who were newly diagnosed with primary myelodysplastic syndrome or acute myeloid leukemia (AML) M6 or M7 were compared to children with de novo AML M0-M5. All children were entered on the Children's Cancer Group therapeutic research study CCG 2891. The presentation and outcomes of the 132 children diagnosed with MDS (60 children), AML FAB M6 (19 children), or AML FAB M7 (53 children) were similar. Children with AML FAB M7 were diagnosed at a significantly younger age (P = 0.001). Children with MDS, M6, or M7 had significantly lower white blood cell (WBC) counts (P = 0.001), lower peripheral blast counts (P M6 and AML M7 resemble MDS in presentation, poor induction success rates, and outcomes.

    The non-donor-stabilized PSnP pincer-type stannylene Sn(NCH2PtBu2)2C6H4 (1) has been prepared by treating SnCl2 with Li2(NCH2PtBu2)2C6H4. All attempts to synthesize the analogous PSiP silylene by reduction of the (previously unknown) silanes SiCl2(NCH2PtBu2)2C6H4 (2), SiHCl(NCH2PtBu2)2C6H4 (3) and SiH(HMDS)(NCH2PtBu2)2C6H4 (4; HMDS = N(SiMe3)2) have been unsuccessful. The almost planar (excluding the tert-butyl groups) molecular structure of stannylene 1 (determined by X-ray crystallography) has been rationalized with the help of DFT calculations, which have shown that, in the series of diphosphanetetrylenes E(NCH2PtBu2)2C6H4 (E = C, Si, Ge, Sn), the most stable conformation of the compounds with E = Ge and Sn has both P atoms very close to the EN2C6H4 plane, near (interacting with) the E atom, whereas for the compounds with E = C and Si, both phosphane groups are located at one side of the EN2C6H4 plane and far away from the E atom. The size of the E atom and the strength of stabilizing donor-acceptor PE interactions (both increase on going down in group 14) are key factors in determining the molecular structures of these diphosphanetetrylenes. The syntheses of the chloridostannyl complexes [Rh{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η4-cod)] (5), [RuCl{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η6-cym)] (6) and [IrCl{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η5-C5Me5)] (7) have demonstrated the tendency of stannylene 1 to insert its Sn atom into M-Cl bonds of transition metal complexes and the preference of the resulting PSnP chloridostannyl group to act as a κ2Sn,P-chelating ligand, maintaining an uncoordinated phosphane fragment. X-ray diffraction data (of 6), 31P{1H} NMR data (of 5-7) and DFT calculations (on 6) are consistent with the existence of a weak PSn interaction involving the non-coordinated P atom of complexes 5-7, similar to that found in stannylene 1.

    Diabetes is a significant health concern, both in the UK and globally. Management can be complex, often requiring high levels of knowledge and skills in order to provide high-quality and safe care. The provision of good, safe, quality care lies within the foundations of healthcare education, continuing professional development and evidence-based practice, which are inseparable and part of a continuum during the career of any health professional. Sound education provides the launch pad for effective clinical management and positive patient experiences. This position paper reviews and discusses work undertaken by a Working Group under the auspices of Diabetes UK with the remit of considering all health professional educational issues for people delivering care to people with diabetes. This work has scoped the availability of education for those within the healthcare system who may directly or indirectly encounter people with diabetes and reviews alignment to existing competency frameworks within the UK's National Health Service. © 2011 The Authors.

    Full Text Available Background: The Falsified Medicines Directive (FMD is a response of the European Union to the increasing number of falsified medicines present in the legal supply chain within the Member States of the community. Effective implementation of the new regulations will depend on the effective cooperation of all parties involved in the distribution of medicinal products including the managers of pharmaceutical companies. Objective: The objective of the study was to examine awareness of the Implementation of the FMD among pharmaceutical company professionals in the European Economic Area. Methods: Sampling was conducted using a method called purposive sampling. An appropriate research tool in the form of an original questionnaire was made available to the respondents in electronic form. During the period from January 2016 to June 2016, 1,496 e-mail messages were sent. The response rate was 17.37%. Results: The study included 99 women (39.3% and 153 men (60.7%. In the study group, 95.7% of people had heard of FMD. Doctors had rarely heard about the falsified medicine directive when compared to pharmacists (p=0.0063, people working in the pharmaceutical industry (p=0.0014, and respondents with a different professional profile (p=0.0114. In the study group, 89.6% of people were aware of the role of National Medicines Verification Organization in the process of implementing the provisions of FMD into the national system of distribution of medicinal products. The number of the respondents who knew the deadline for the implementation of FMD was significantly higher in the study population, i.e. 91.9% (p=0.0001. Both the younger respondents and those with lower level of education were less aware of the time requirements posed to national regulators (p=0.0003, p=0.0023, respectively. Conclusions: Awareness of the regulations related to the implementation of the FMD, although relatively high among pharmaceutical company professionals in the EEA, is still

    Professional burnout syndrome has been described in association with insomnia and metabolic, inflammatory and immune correlates. We investigated the interest of exploring biological parameters and sleep disturbances in relation to burnout symptoms among white-collar workers. Fifty-four participants with burnout were compared to 86 healthy control participants in terms of professional rank level, sleep, job strain (Karasek questionnaire), social support, anxiety and depression (HAD scale). Fasting concentrations of glycaemia, glycosylated hemoglobin (HbA1C), total-cholesterol, triglycerides, C-reactive protein (CRP), thyroid stimulating hormone (TSH), 25-hydroxyvitamin D (25[OH]D), and white blood cell (WBC) counts were assessed. Analysis of variance and a forward Stepwise Multiple Logistic Regression were made to identify predictive factors of burnout. Besides reporting more job strain (in particular job control p = 0.02), higher levels of anxiety (pburnout presented higher levels of HbA1C, glycaemia, CRP, lower levels of 25(OH)D, higher number of leukocytes, neutrophils and monocytes (P 3.5%, the prevalence of burnout increases from 16.6% to 60.0% (OR = 4.3, 95%CI = 2.8–6.9). Strong significant positive correlation existed between HbA1C and the two dimensions (emotional exhaustion and depersonalization (r = 0.79 and r = 0.71, pburnout. Models including job strain, job satisfaction, anxiety and insomnia did not predict burnout (p = 0.30 and p = 0.50). However, when HbA1C levels is included, the prediction of burnout became significant (P = 0.03). Our findings demonstrated the interest of sleep and biological parameters, in particular HbA1C levels, in the characterization of professional burnout. PMID:29385150

    To establish the norm of occupational stress on the professionals in Chengdu and Chongqing area. According to the "Occupation Sorting Canon in the People's Republic of China", the professionals of the above-mentioned area were sorted out and randomly stratified. The normative data were derived from a sample of 2 064 participants. The modified Occupation Stress Inventory Revised Edition (OSI-R) was used to test the targets' occupational stress level (including stressors, strain and coping resources). (1) In these professionals, the sex ratio was about 1:1, average age (36.4 +/- 9.4) years, average length of service (15.9 +/- 10.0) years, 63.07% people were college educated and over 80% married. (2) Descriptive statistics for OSI-R scale scores for the total normative sample, for gender samples and for occupational group samples were modulated. (3) The gender norm showed that there were heavier role overload and stronger occupational strains in males than those in females (P 0.05). (4) In terms of different occupations, the scores of occupational role and personal strain among various groups indicated significant differences (P 0.05). (5) The major factors influencing OSI-R were sex, occupation and length of service. The norm established can basically represent the occupational stress on professionals in Chengdu and Chongqing area.

    We describe some of our results from a joint experimental and theoretical program concerning elastic electron scattering by 138 Ba(...6s6p 1 P 1 ) atoms. From the experimental results, we derived various scattering parameters and magnetic sublevel specific differential elastic scattering cross sections at impact energy (E 0 ) of 20.0 eV and at scattering angles (θ) of 10deg, 15deg, and 20deg. The same parameters and cross sections were calculated by the convergent close coupling (CCC) approximation and compared to the experimental results. An excellent agreement, found for the two sets of data, gave us confidence in the CCC method and allowed us to extend the angular and energy ranges for the purpose of generating integral elastic scattering cross sections needed for the deduction of the alignment creation cross sections.

We measured static, kinetic, and dynamic visual acuity (SVA, KVA, and DVA, respectively of Japanese professional baseball players to ascertain whether there would be any difference in SVA, KVA, and DVA among player groups stratified according to their performance level. Methods: The subjects were 102 male professional baseball players with a mean age of 26 years who were members of a Japanese professional baseball club from 2000 to 2009. They were stratified into three groups according to their performance level: A (players who were on the roster of the top-level team all the time throughout the study period, B (players who were on the roster of the top-level team sometimes but not all the time, and C (players who were never on the roster of the top-level team. They were interviewed for the use of corrective visual aids, and examined for SVA, KVA, and DVA. The measurements of these parameters were compared among groups A, B, and C. We also investigated and analyzed the association of KVA or DVA with player position (pitchers or fielders and with hand dominance for batting. KVA was compared between the pitchers and the fielders because they each require different playing skills. DVA was compared between the right-handed and the left-handed batters. Results: There was no statistically significant difference among groups A, B, and C. There was a statistically significant difference in

    Lactobacillus species produce biosurfactants that can contribute to the bacteria's ability to prevent microbial infections associated with urogenital and gastrointestinal tracts and the skin. Here, we described the biological and physicochemical properties of biosurfactants produced by Lactobacillus jensenii P 6A and Lactobacillus gasseri P 65 . The biosurfactants produced by L. jensenii P 6A and L. gasseri P 65 reduced the water surface tension from 72 to 43.2 mN m -1 and 42.5 mN m -1 as their concentration increased up to the critical micelle concentration (CMC) values of 7.1 and 8.58 mg mL -1 , respectively. Maximum emulsifying activity was obtained at concentrations of 1 and 5 mg mL -1 for the P 6A and P 65 strains, respectively. The Fourier transform infrared spectroscopy data revealed that the biomolecules consist of a mixture of carbohydrates, lipids and proteins. The gas chromatography-mass spectrum analysis of L. jensenii P 6A biosurfactant showed a major peak for 14-methypentadecanoic acid, which was the main fatty acid present in the biomolecule; conversely, eicosanoic acid dominated the biosurfactant produced by L. gasseri P 65 . Although both biosurfactants contain different percentages of the sugars galactose, glucose and ribose; rhamnose was only detected in the biomolecule produced by L. jensenii P 6A . Emulsifying activities were stable after a 60-min incubation at 100 °C, at pH 2-10, and after the addition of potassium chloride and sodium bicarbonate, but not in the presence of sodium chloride. The biomolecules showed antimicrobial activity against clinical isolates of Escherichia coli and Candida albicans, with MIC values of 16 µg mL -1 , and against Staphylococcus saprophyticus, Enterobacter aerogenes and Klebsiella pneumoniae at 128 µg mL -1 . The biosurfactants also disrupted preformed biofilms of microorganisms at varying concentrations, being more efficient against E. aerogenes (64%) (P 6A biosurfactant), and E. coli (46

    Nursing graduates acquire their nursing values by professional socialization. Mentoring is a crucial support mechanism for these novice nurses, yet little is known about the model C clinical nurse leader graduate and the effects of mentoring. This investigation examined how mentoring affected the development of professional nursing values in the model C clinical nurse leader graduate. A longitudinal design was used to survey model C clinical nurse leader graduates before and after graduation to determine how different types of mentoring relationships influenced professional values. Demographic surveys documented participant characteristics and the Nurses Professional Values Scale - Revised (NPVS-R) assessed professional nursing values. Mean NPVS-R scores increased after graduation for the formally mentored participants, while the NPVS-R scores decreased or remained unchanged for the other mentoring groups. However, no significant difference was found in NPVS-R scores over time (p = .092) or an interaction between the NPVS-R scores and type of mentoring relationships (p = .09). These results suggest that model C clinical nurse leader graduate participants experiencing formal mentoring may develop professional nursing values more than their colleagues. Formal mentoring relationships are powerful and should be used to promote professional values for model C clinical nurse leader graduates. © 2018 John Wiley & Sons Ltd.

    Leadership by health care professionals is likely to vary because of differences in the social contexts within which they are situated, socialization processes and societal expectations, education and training, and the way their professions define and operationalize key concepts such as teamwork, collaboration, and partnership. This research examines the effect of the nurse and physician leaders on interdependence and encounter preparedness in chronic disease management practice groups. The aim of this study was to examine the effect of complementary leadership by nurses and physicians involved in jointly producing a health care service on care team functioning. The design is a retrospective observational study based on survey data. The unit of analysis is heart failure care groups in U.S. Veterans Health Administration medical centers. Survey and administrative data were collected in 2009 from 68 Veterans Health Administration medical centers. Key variables include nurse and physician leadership, interdependence, psychological safety, coordination, and encounter preparedness. Reliability and validity of survey measures were assessed with exploratory factor analysis and Cronbach alphas. Multivariate analyses tested hypotheses. Professional leadership by nurses and physicians is related to encounter preparedness by different paths. Nurse leadership is associated with greater team interdependence, and interdependence is positively associated with respect. Physician leadership is positively associated with greater psychological safety, respect, and shared goals but is not associated with interdependence. Respect is associated with involvement in learning activities, and shared goals are associated with coordination. Coordination and involvement in learning activities are positively associated with encounter preparedness. By focusing on increasing interdependence and a constructive climate, nurse and physician leaders have the opportunity to increase care coordination

    Improving mechanisms for knowledge translation (KT) and connecting decision-makers to each other and the information and evidence they consider relevant to their work remains a priority for public health. Virtual communities of practices (CoPs) potentially offer an affordable and flexible means of encouraging connection and sharing of evidence, information and learning among the public health community in ways that transgress traditional geographical, professional, institutional and time boundaries. The suitability of online CoPs in public health, however, has rarely been tested. This paper explores the reasons why particular online CoP for alcohol harm reduction hosted by the UK Health Forum failed to generate sufficient interest from the group of public health professionals at which it was aimed. The study utilises online web-metrics demonstrating a lack of online activity on the CoP. One hundred and twenty seven responses to an online questionnaire were used to explore whether the lack of activity could be explained by the target audience's existing information and evidence practices and needs. Qualitative interviews with 10 members describe in more detail the factors that shape and inhibit use of the virtual CoP by those at which it was targeted. Quantitative and qualitative data confirm that the target audience had an interest in the kind of information and evidence the CoP was set up to share and generate discussion about, but also that participants considered themselves to already have relatively good access to the information and evidence they needed to inform their work. Qualitative data revealed that the main barriers to using the CoP were a proliferation of information sources meaning that participants preferred to utilise trusted sources that were already established within their daily routines and a lack of time to engage with new online tools that required any significant commitment. Specialist online CoPs are competing for space in an already crowded

  17. Job Satisfaction and Organizational Commitment: Affective Commitment Predictors in a Group of Professionals

    Ferretti, Maria Santa

    Job satisfaction and organizational commitment have long been identified as relevant factors for the well-being of individuals within an organization and the success of the organization itself. As the well-being can be, in principle, considered as emergent from the influence of a number of factors, the main goal of a theory of organizations is to identify these factors and the role they can play. In this regard job satisfaction and organizational commitment have been often identified with structural factors allowing an organization to be considered as a system, or a wholistic entity, rather than a simple aggregate of individuals. Furthermore, recent studies have shown that job satisfaction has a significant, direct effect on determining individuals' attachment to an organization and a significant but indirect effect on their intention to leave a company. However, a complete assessment of the role of these factors in establishing and keeping the emergence of an organization is still lacking, due to shortage of measuring instruments and to practical difficulties in interviewing organization members. The present study aims to give a further contribution to what is currently known about the relationship between job satisfaction and affective commitment by using a group of professionals, all at management level. A questionnaire to measure these constructs, following a pilot study, was designed and administered to 1042 participants who were all professionals and had the title of industrial manager or director. The factors relating to job satisfaction and the predictive value of these factors (to predict an employee's emotional involvement with their organization) were simultaneously tested by a confirmative factorial model. The results were generalized with a multi-sample procedure by using models of structural equations. This procedure was used to check whether these factors could be considered or not as causes producing the measured affective commitment. The results

    Previous measurements of the 6 GeV/c p - p elastic scattering rates have been extended with beam and target polarizations normal to the scattering plane. Improvements to the measuring technique include additional momentum resolution added to the recoil arm and increased solid angle resulting from two-element hodoscopes. Beam intensity was increased by a factor of 3 and additional shielding was installed. Along with the usual statistical uncertainty and errors in measurement of the target polarization, a term was added in quadrature due to a systematic difference between target and beam asymmetries (A/sub T/ and A/sub B/)

    2011-01-01

    Background HIV-1 viruses are categorized into four distinct groups: M, N, O and P. Despite the same genomic organization, only the group M viruses are responsible for the world-wide pandemic of AIDS, suggesting better adaptation to human hosts. Previously, it has been reported that the group M Vpu protein is capable of both down-modulating CD4 and counteracting BST-2/tetherin restriction, while the group O Vpu cannot antagonize tetherin. This led us to investigate if group O, and the related group P viruses, possess functional anti-tetherin activities in Vpu or another viral protein, and to further map the residues required for group M Vpu to counteract human tetherin. Results We found a lack of activity against human tetherin for both the Vpu and Nef proteins from group O and P viruses. Furthermore, we found no evidence of anti-human tetherin activity in a fully infectious group O proviral clone, ruling out the possibility of an alternative anti-tetherin factor in this virus. Interestingly, an activity against primate tetherins was retained in the Nef proteins from both a group O and a group P virus. By making chimeras between a functional group M and non-functional group O Vpu protein, we were able to map the first 18 amino acids of group M Vpu as playing an essential role in the ability of the protein to antagonize human tetherin. We further demonstrated the importance of residue alanine-18 for the group M Vpu activity. This residue lies on a diagonal face of conserved alanines in the TM domain of the protein, and is necessary for specific Vpu-tetherin interactions. Conclusions The absence of human specific anti-tetherin activities in HIV-1 group O and P suggests a failure of these viruses to adapt to human hosts, which may have limited their spread.

    This paper studies the influence of a Scientific Initiation Programme (SIP) on the professional profile of new doctors from a Brazilian university. Evaluate fifty-two new doctors divided into two groups matched by sex, age and academic performance and differing only in participation in the SIP. Professional and socioeconomic data were collected, including schooling of parents; average income before, during and after the medical course; current professional situation; results of exams for civil servant recruitment; and titles and degrees obtained after graduation. Significant differences were found only in civil servant recruitment exam results (p = 0.0098) and in income after graduation (p = 0.02), which were both higher in the non-SIP group. Only one doctor got a M.Sc. degree after graduation, but many of them in both groups obtained technical titles, and had papers presented at congresses or published. Apparently, taking part in a SIP led to lower income and worse civil servant recruitment exam results. However, this may only reflect a transient phase in a long-term process. New research currently under way will answer this remaining question, now that more time has elapsed since graduation.

    We report the first examples of quinary rare earth thiophosphates with a fully ordered cation and anion distribution, Cs{sub 5}Ln{sub 3}X{sub 3}(P{sub 2}S{sub 6}){sub 2}(PS{sub 4}), (Ln = La, Ce and X = Br, Cl) as well as the quasi-quaternary Cs{sub 10}Y{sub 4}Cl{sub 10}(P{sub 2}S{sub 6}){sub 3}. These four new compounds crystallize in three different, unknown structure types. The yellowish, transparent, brittle Cs{sub 5}Ce{sub 3}Br{sub 3}(P{sub 2}S{sub 6}){sub 2}(PS{sub 4}) crystallizes in the orthorhombic space group Pnma (no. 62) with a = 13.276(3), b = 14.891(3), c = 19.593(4) Aa, and V = 3873(1) Aa{sup 3} in a novel structure type. Colorless crystals of Cs{sub 5}La{sub 3}Br{sub 3}(P{sub 2}S{sub 6}){sub 2}(PS{sub 4}) and Cs{sub 5}La{sub 3}Cl{sub 3}(P{sub 2}S{sub 6}){sub 2}(PS{sub 4}) are isotypic and were obtained in the monoclinic space group P2{sub 1}/m (no. 11) with a = 9.715(2), b = 14.310(3), c = 13.685(3) Aa, β = 100.16(3) and V = 1873(1) Aa{sup 3} and a = 9.513(2), b = 14.182(3), c = 13.699(3) Aa, β = 99.39(3) and V = 1823(1) Aa{sup 3}, respectively. Both structures contain isolated hexathiohypodiphosphate(IV) [P{sub 2}S{sub 6}]{sup 4-} and thiophosphate [PS{sub 4}]{sup 3-} units that are arranged alternately in layers. Cs{sub 10}Y{sub 4}Cl{sub 10}(P{sub 2}S{sub 6}){sub 3} crystallizes in colorless transparent platelets in the orthorhombic space group Pnnm (no. 58) with a = 13.153(3), b = 28.964(6), c = 7.780(2) Aa, and V = 2964(1) Aa{sup 3}. The structure is composed of isolated [P{sub 4/2}S{sub 6}]{sup 4-} octahedra containing four half occupied P positions surrounded octahedrally by sulfur. We show with Raman scattering that this disordered thiophosphate anion shows a Raman spectrum that is distinct from spectra published for other literature-known thiophosphate anions.

    Full Text Available The title compound, [Ru(CO3(η6-C6H6{(C6H112P(CH2C10H7}]·3CHCl3, was synthesized by carbonation of [RuCl2(η6-C6H6{(C6H112P(CH2C10H7}] with NaHCO3 in methanol at room temperature. The RuII atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand in a piano-stool configuration. The crystal packing is consolidated by C—H...O and C—H...Cl hydrogen-bonding interactions between adjacent metal complexes and between the complexes and the solvent molecules. The asymmetric unit contains one metal complex and three chloroform solvent molecules of which only one was modelled. The estimated diffraction contributions of the other two strongly disordered chloroform solvent molecules were substracted from the observed diffraction data using the SQUEEZE procedure in PLATON [Spek (2009. Acta Cryst. D65, 148–155].

    A total of seven new families and sixteen structurally different inorganic materials with point group 6 are shown to satisfy the criteria presented previously by the present author for predicting ferroelectricity. In case each prediction is experimentally verified, the 183 individual entries for point group 6 listed in the Inorganic Crystal Structure Database will result in over 80 new ferroelectrics, of which about 30 are rare-earth isomorphs.

    at 0.05. Results: Professional and Corega adhesives had more neutral pH than that of Fittydent and Fixodent which were more acidic. Washability test showed no remaining mass of any adhesive and there was not any statistically significant difference between groups (P>0.05. Fittydent and Corega adhesives showed higher bond strength than that of Professional and Fixodent and this difference was statistically significant (P<0.05. Conclusion: Professional and Corega adhesives had less acidity. Thus they cause less harmful effects on the oral mucosa than that of Fittydent and Fixodent and should be indicated in patients with little-tolerant oral mucousa such as diabetous, iron-deficiency anemia and hypertention. All the groups had acceptable washability. Fittydent and Corega had higher bond strength than that of Professional and Fixodent. Therefore in complete-denture-wearers who require more retention as a result of severe ridge resorption, macrotruma, and maladaptiivity, Fittydent and Corega seems to be more acceptable.

  8. Biochemical and functional analysis of two Plasmodium falciparum blood-stage 6-cys proteins: P12 and P41.

    Full Text Available The genomes of Plasmodium parasites that cause malaria in humans, other primates, birds, and rodents all encode multiple 6-cys proteins. Distinct 6-cys protein family members reside on the surface at each extracellular life cycle stage and those on the surface of liver infective and sexual stages have been shown to play important roles in hepatocyte growth and fertilization respectively. However, 6-cys proteins associated with the blood-stage forms of the parasite have no known function. Here we investigate the biochemical nature and function of two blood-stage 6-cys proteins in Plasmodium falciparum, the most pathogenic species to afflict humans. We show that native P12 and P41 form a stable heterodimer on the infective merozoite surface and are secreted following invasion, but could find no evidence that this complex mediates erythrocyte-receptor binding. That P12 and P41 do not appear to have a major role as adhesins to erythrocyte receptors was supported by the observation that antisera to these proteins did not substantially inhibit erythrocyte invasion. To investigate other functional roles for these proteins their genes were successfully disrupted in P. falciparum, however P12 and P41 knockout parasites grew at normal rates in vitro and displayed no other obvious phenotypic changes. It now appears likely that these blood-stage 6-cys proteins operate as a pair and play redundant roles either in erythrocyte invasion or in host-immune interactions.

    Professional values are abstract and general behavioral principles that provide basic standards to judge aims and actions, and these principles are formed by strong emotional loyalty of members of the profession. Research was conducted to compare the career choice and professional values of nursing students at two universities in the upper Midwest of the United States and in the middle of Turkey. A descriptive and comparative design was used. The participants of the study were comprised nursing students from a university in the upper Midwest of United States and a university in the middle of Turkey. The sample consisted of 728 students in all grades. Data were collected by a questionnaire, The Nurses Professional Values Scale-Revised and Vocational Choices in Entering Nursing Scale. Number, percentage distribution, mean, standard deviation, t test, and one-way variance analysis were used in the analysis of data. Ethical considerations: Ethical approval was obtained from the Ethics Commission. Informed consent was received from the students. The students' mean age for American students was 24.3 ± 5.6 years, while the mean age for Turkish students was 19.8 ± 1.7 years. Mean score of American students on The Vocational Congruency (a subgroup of the Vocational Choices in Entering Nursing Scale) was 38.5 ± 5.9 and Turkish students was 29.6 ± 8.9 (p Values Scale-Revised was 109.2 ± 12.3 and that of Turkish students was 101.6 ± 17.0. This study concluded that the majority of nursing students had high professional values, and when students' scores were compared, American students had higher professional values, and in career choice, they considered primarily fitness of the profession to themselves and their goals, while Turkish students primarily thought of their living conditions.

    Stress levels are evident among health professionals. However, there are few studies on sensory-based self-care aimed at stress management, self-esteem and subjective well-being in this group of professionals. To assess the impact of a self-care intervention mediated by the senses on the stress levels, self-esteem and well-being of health professionals in a hospital environment. A total of 93 health professionals participated in an unblinded clinical trial, randomized into four groups: 1) control (no intervention); 2) Monosensory-daily body moisturizing (DBM) with odorless cream; 3) Bisensory-DBM with scented cream; 4) Multisensory-DBM with scented cream associated with audiovisual material. Participants answered specific questionnaires to assess stress, self-esteem and well-being and cortisol samples were collected at baseline, 15 and 30 days following intervention, and at the 30-day follow-up. Self-care was characterized as neglected, with most participants reporting inadequate hours of sleep (74%), irregular physical activity (68%), and inadequate nutrition (45%). Compared to the other groups, the Bisensory group had lower stress on all three assessments (p = 0.017; 0.012; 0.036), a life satisfaction 8% higher at follow-up than at baseline (95% CI: 2% to 15%, p = 0.016), a 10% increase in positive affect (95% CI: 2% to 19%, p = 0.011) and a 12% reduction in negative affect (95% CI: 3% to 21% less, p = 0.014) after 30 days. The Multisensory group showed improvement in self-esteem (p = 0.012) and reduced cortisol (p = 0.036) after 30 days of intervention. The control group showed no changes in the variables studied, except for cortisol: an increase at the 15-day evaluation (denoting higher risk for stress, p = 0.009) and a reduction at follow-up (p = 0.028), which was nevertheless within normal levels.

    Full Text Available In order to evaluate the occupational exposure of dental professionals to metallic mercury in dental offices of a public primary health care in the city of Maringá, Brazil, samples of blood and urine were collected from 149 dental professionals (group exposed, and 51 healthy adults similar for age and gender of the exposed group (control group in September and October, 2008. Urinary mercury was determined using atomic absorption spectrophotometry, urea and creatinine in blood and urine by UV/VIS spectrophotometry and analysis of physical, chemical and microbiological characteristics of the urine by reactive bands. The program ‘Statistic’ version 7.1 and the software R version 2.6.2 were used for the statistical calculations. Urinary mercury was 2.08 ± 2.11 µg g-1 creatinine in workers exposed to mercury and 0.36 ± 0.62 µg g-1 creatinine in the control group (p -1 creatinine; 11% of these professionals (n = 16 had mercury levels above the reference value (5.0 µg g-1 creatinine, whereas the maximum value found was 13 µg g-1 creatinine. The dental professionals of public primary health care in the city of Maringa was exposed to metallic mercury at levels 5.8 times higher than the non-exposed subjects.

    Cytochrome P450 2B6 (CYP2B6) is an important drug-metabolizing enzyme and is expressed in liver. Although human CYP2B6 variants account for variable enzyme properties among individuals and populations, CYP2B6 genetic variants have not been investigated in cynomolgus macaques, widely used in drug metabolism studies. CYP2B6 was resequenced in 120 cynomolgus macaques and 23 rhesus macaques by direct sequencing. Twenty-three non-synonymous variants were found, of which 12 and 3 were unique to cynomolgus macaques and rhesus macaques, respectively. By functional characterization using the 14 variant proteins, 8 variants (V114I, R253C, M435I, V459M, L465P, C475S, R487C, and R487H) showed different rate (>1.5-fold) of testosterone 16β-hydroxylation to wild type. However, the four variants (M435I, L465P, C475S, and R487H) were analyzed in liver microsomes, and the catalytic rates were not substantially different from wild type. Macaque CYP2B6 was polymorphic, and the genotype could partly account for variable enzyme activities of macaque CYP2B6. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Background: Ankle sprain is one of the major causes of disability in professional footballers. Objective of this study was to find out the effectiveness and to compare the effectiveness of the proprioceptive training and technical training immediately after the end of the treatment and after three months follow up in prevention of recurrent ankle sprain among professional footballers. Methods: 30 subjects with previous history of grade I or grade II ankle sprain, within one year were selected for the study. They were randomly divided into two groups equally treadmill 15 in each group A and group B. Group A and B received five minutes of warm-up by brisk walk on treadmill. Group A and B underwent 20 minutes of unilateral balance board training and unilateral vertical jump respectively. Results: Pre and post data were analyzed using Mann-Whitney test, Wilcoxon’s sign rank test, paired‘t’ test. Intra group analysis showed that both groups have shown significant improvement with P < 0.001, after the treatment. Inter group were analyzed the post scores of both groups and found no significant difference on proprioceptive training over technical training on recurrence of ankle sprain among professional footballers. Conclusion: The study concluded that proprioceptive and technical training are equally effective on prevention of recurrent ankle sprain among professional footballers with previous history of grade I or grade II ankle sprain.

    This investigation presents two studies with the goal of adapting and validating a short version of the Group Environment Questionnaire in the Spanish sport context with professional players. Study 1 used a sample of 377 male soccer players aged between 18 and 39 years ( M = 24.51, SD = 3.73), in a preliminary study using exploratory factor analysis. Study 2 used a sample of 604 professional male and female athletes, ages between 15 and 38 years ( M = 24.34, SD = 4.03). The data analyzed were collected at three moments of the season. For each measurement, we developed seven first- and second-order structures that were analyzed with confirmatory factor analysis. Study 1 indicated appropriate factorial validity (> .60) and internal consistency (> .70), with only Item 3 presenting a low factor loading (.11), so its drafting was modified in the next study. Study 2 revealed that the Spanish version of the GEQ has high levels of internal consistency (> .70) and acceptable fit index values in its original four first-order factor structure in all three measurements ( χ²/df = 4.39, CFI = .95, IFI = .95, RMSEA = .07, SRMR = .04, AIC = 271.09). Discriminant validity (from r = .45 to r = .72) and concurrent validity (from r = .21 to r = .60) also presented appropriate values. Lastly, we conducted analysis of invariance, confirming that the models established in the different measurements were invariant. The short 12-item adaptation of the GEQ to Spanish is a valid and reliable instrument to measure team cohesion in professional male and female soccer players.

    Capturing either lapses or excellence in behaviors related to medical professionalism is difficult. The authors report a mixed-methods analysis of a novel mobile platform for assessing medical professionalism in a training environment. A mobile Web-based platform to facilitate professionalism assessment in a situated clinical setting (Professional Mobile Monitoring of Behaviors [PROMOBES]) was developed. A professionalism framework consisting of six domains (reliability, adaptability, peer relationships, upholding principles, team relationships, and scholarship) encompassing 25 subelements underpins the reporting structure. This pilot study involved 26 faculty supervising 93 medical trainees at two sites from January 12 to August 8, 2016. Notable professionalism behaviors were linked to the framework domains and elements; narrative details about incidences were captured on mobile devices. Surveys gauged the technological functionality and impact of PROMOBES on faculty assessment of professionalism. Qualitative focus groups were employed to elucidate user experience. Although users anticipated PROMOBES's utility would be for reporting lapses in professionalism, 94.7% of reports were for commendation. Comfort assessing professionalism (P = .04) and recognition of the reporting procedures for professionalism-related concerns (P = .01) improved. PROMOBES attained high acceptance ratings. Focus group analysis revealed that the explicit connection to the professionalism framework was powerful; similarly, the near real-time reporting capability, multiple observer inputs, and positive feedback facilitation were strengths. Making the professionalism framework visible and accessible via a mobile platform significantly strengthens faculty knowledge and behaviors regarding assessment. The strong desire to capture positive behaviors was an unexpected finding.

Knowing who to call for potential HT victims increased from 7.2% to 59% in the intervention group and was unchanged (15%) in the delayed intervention comparison group (61.4% [28.5%-94.4%]; P < 0.01). The proportion of participants who suspected their patient was a victim of HT increased from 17% to 38% in the intervention group and remained unchanged (10%) in the delayed intervention comparison group (20.9 [8.6%-33.1%]; P < 0.01). A brief educational intervention increased ED provider knowledge and self-reported recognition of HT victims.

    Women's addiction to alcohol remains a taboo subject, whereas one third of alcohol-dependent people are female. Social representations concerning them are very unfavorable. Their alcoholism is usually accompanied by strong feelings of guilt, depreciation and lowered self-esteem. There is little existing work about self-esteem in women who have become abstinent. This study's goal is to compare the self-esteem of women who are alcohol-dependent and the self-esteem of women who have become abstinent in various domains (social, familial, professional). The sample contained 71 women divided into three groups: 31 alcohol-dependent women (average age of 44.9); 20 alcohol-dependent women who had become abstinent for at least two months (average age of 44.7) and 20 women who formed the control group (average age of 44.4). The material was put together from the Self-Esteem Inventory (SEI, adult version of Coopersmith 1981). It includes 58 items divided into four sub-categories (general self-esteem, social, familial and professional) and a scale for falsehoods. The SEI was self-administered. The statistics were produced entirely with non-parametric tests: Mann-Whitley U Test for the comparison of two independent samples and Kruskal-Wallis Anova for the comparison of three independent samples. A significant difference was found for general self-esteem (P=0.001), familial (P=0.01) and professional (P=0.03) between the three groups of women (alcohol-dependent, alcohol-dependent who had become abstinent and women from the control group). There was no statistical difference for social self-esteem or the lying scale. There was a difference between alcohol-dependent women and the control group in general self-esteem (P=0.0001), familial self-esteem (P=0.01) and professional self-esteem (P=0.002), as well as between women who had become abstinent and women from the control group in general self-esteem (P=0.02), familial self-esteem (P=0.005) and professional self-esteem (P=0.07; ns

    PHOENIX-P is a lattice physics code system, developed by the Westinghouse Electric Corporation (WEC), which was transplanted and used at Dayabay Nuclear Power Plant (DNPJVC). The associated multi-group (42-group) library was derived from the evaluated nuclear data of ENDF/B-5. Since the original library is from the old evaluated nuclear data, it can not meet all the requirements of reactor physics calculations of the nuclear power plant. So it is necessary to update the library with the latest version of evaluated nuclear data. To do so, based on the investigation of the old library and the information about the library, some programs were developed at China Nuclear Data Center (CNDC) to produce PHOENIX-P format data sets mainly from CENDL-2 and the new data were used to supersede the old ones of the PHOENIX-P library

    To examine the impact of healthcare professional versus patient goal setting for the self-management of intermittent allergic rhinitis (AR) on symptom severity and quality of life. This was a 6 week, parallel group study. Group A participants, with pharmacist facilitation, nominated personally relevant goals and strategies relating to their AR. Group B participants had their goals and strategies set by the pharmacist. The main outcome measures used included perceived symptom severity and quality of life. In addition, goals and strategies data from participants of both groups were collected and analysed. Both groups demonstrated significant improvements in symptom severity and quality of life scores however Group B symptom severity scores improved more. Group B set a greater number of goals and strategies which were better structured and more task specific. This is the first study to investigate the impact of goal setting on patient behaviour in a chronic yet episodic illness. Our results suggest that self-management goals set by the healthcare professional which are clinically indicated but tailored to the patient's nominated symptoms yields better outcomes than goals nominated by the patient. A brief, structured intervention, tailored to patient symptoms, can enhance self-management of intermittent allergic rhinitis.

    Idiopathic pulmonary fibrosis (IPF) is a disease with a poor prognosis and very few available treatment options. The involvement of the purinergic receptor subtypes P2Y2 and P2X7 in fibrotic lung disease has been demonstrated recently. In this study, we investigated the role of P2Y6 receptors in the pathogenesis of IPF in humans and in the animal model of bleomycin-induced lung injury. P2Y6R expression was upregulated in lung structural cells but not in bronchoalveolar lavage (BAL) cells derived from IPF patients as well as in animals following bleomycin administration. Furthermore, BAL fluid levels of the P2Y6R agonist uridine-5′-diphosphate were elevated in animals with bleomycin-induced pulmonary fibrosis. Inflammation and fibrosis following bleomycin administration were reduced in P2Y6R-deficient compared to wild-type animals confirming the pathophysiological relevance of P2Y6R subtypes for fibrotic lung diseases. Experiments with bone marrow chimeras revealed the importance of P2Y6R expression on lung structural cells for pulmonary inflammation and fibrosis. Similar effects were obtained when animals were treated with the P2Y6R antagonist MRS2578. In vitro studies demonstrated that proliferation and secretion of the pro-inflammatory/pro-fibrotic cytokine IL-6 by lung fibroblasts are P2Y6R-mediated processes. In summary, our results clearly demonstrate the involvement of P2Y6R subtypes in the pathogenesis of pulmonary fibrosis. Thus, blocking pulmonary P2Y6 receptors might be a new target for the treatment of IPF. PMID:28878780

    To compare infant pain knowledge between a group of nurses who work in a pediatric hospital and one that works in a general hospital. Descriptive study based on the use of a validated questionnaire for assessing the knowledge and attitudes of nurses about pediatric pain (Pediatric Nurses' Knowledge and Attitude Survey Regarding Pain [PNKAS]). PNKAS questionnaire was distributed to the nursing staff of a pediatric hospital and a general hospital and the results were compared. The average score obtained in the pediatric vs. the general hospital was: mean, 51.7% vs. 47.2%, 95% confidence interval, 47.5 to 56% vs. 43.6 to 50.8% (P=.098). There were no differences between the scores in the PNKAS questionnaire between nurses working exclusively with children and nurses working with general population.

    (1) To investigate Egyptian obstetricians' views towards cesarean delivery on maternal request, (2) to investigate Egyptian obstetricians' views towards some of the "potentially neglected" or controversial obstetrical skills or maneuvers as external cephalic version (ECV), fetal scalp pH measurement or tubal ligation during CS and (3) to examine the effect of professional level on the above factors. This is a descriptive study performed at the 8th annual Obstetrics and Gynecology conference of Suez Canal University held at Ismailia city in Egypt in June 2011 via a structured self administered questionnaire. Questionnaire was distributed to 223 conference attendants from the three professional levels (consultants, specialists and registrars) working at the two major institutions in Egypt: University and Ministry of Health. The structured questionnaire was based on informed opinion and professional guidelines. In total, 167 (75%) completed the questionnaire. Cesarean delivery on maternal request was accepted by 66% of the studied group and acceptance was significantly higher among consultants. There was no difference in all physicians' practices of cesarean section in both private and public settings. Limited access to medical equipment such as cardiotocogram (CTG) was shown in consultant group reflecting improper private sector preparations. The study revealed that 59% of obstetricians accepted vaginal breech delivery, and only 14% would consider ECV. Fetal scalp pH taking in cases of abnormal CTG was accepted by only 16.3% and 49% rejected the practice of instrumental delivery. There were significant differences among the three professional and the two institutional groups regarding these attitudes. There were different views regarding tubal sterilization during CS. Lack of knowledge, the need to improve some clinical skills and some professional attitudes may shed light on rising CS rates in Egypt.

    Full Text Available Purpose: The purpose of this study was to examine cortical thickness and subcortical volumes in professional rugby players with an extensive history of concussions compared to control subjects. Method: Participants included 24 active and former professional rugby league players [Age M(SD = 33.3(6.3; Range = 21–44] with an extensive history of concussion and 18 age- and education-matched controls with no history of neurotrauma or participation in contact sports. Participants underwent T1-weighted imaging and completed a neuropsychological battery, including two tests of memory. Whole brain cortical thickness analysis and structural volume analysis was performed using FreeSurfer version 6.0. Results: Professional rugby league players reported greater alcohol consumption (p < .001 and had significantly worse delayed recall of a visually complex design (p = .04. They did not differ from controls on other clinical outcome measures. There were no differences in cortical thickness between the groups. Professional players had smaller whole brain (p = .003, bilateral hippocampi (ps = .03, and left amygdala volumes (p = .01 compared to healthy controls. Within the players group, there were significant associations between greater alcohol use and smaller bilateral hippocampi and left amygdala volumes. There were no associations between structural volumes and history of concussions or memory performance. Conclusions: The literature examining cortical thickness in athletes with a history of multiple concussions is mixed. We did not observe differences in cortical thickness in professional rugby league players compared to controls. However, smaller subcortical volumes were found in players that were, in part, associated with greater alcohol consumption.

    Due to competitiveness and academic benefits, most dental professionals feel an urgent need to increase their publications. Hence, we explored the attitude of students and faculty members toward scientific publications through a questionnaire. A questionnaire consisting of 13 questions was sent by e-mails and posting the printed copies to dental postgraduate (PG) students (second and third year) and faculty members (n = 500 each). The returned completed questionnaires were analyzed. About 37% of dental PG faculty and 35.6% PG students responded to the questionnaire, with overall response of 72.6%. Among the PG faculty, professors (P) had more scientific publications, followed by senior lecturers (SL) and readers (R). The publications as first or corresponding author were less among both faculty and PG students while co-authorship was more among PG students compared to faculty members. Awareness about the term "plagiarism" was overall high and relatively highest among R, followed by SL, P and PG students. The percentage of publications in fee charging journals was more among PG students than faculty members and self-funding for publication was observed in 86.4% of PG students and 94-100% among faculty members. About 72.6% of dental professionals were involved in publishing of their research work and the number of publications increased steadily with an increase in their academic experience. All the dental professionals concurred publications as the criteria for academic excellence.

    Full Text Available Abstract The interaction between the HIV-1 p6 late budding domain and ALIX, a class E vacuolar protein sorting factor, was explored by using the yeast two-hybrid approach. We refined the ALIX binding site of p6 as being the leucine triplet repeat sequence (Lxx4 (LYPLTSLRSLFG. Intriguingly, the deletion of the C-terminal proline-rich region of ALIX prevented detectable binding to p6. In contrast, a four-amino acid deletion in the central hinge region of p6 increased its association with ALIX as shown by its ability to bind to ALIX lacking the proline rich domain. Finally, by using a random screening approach, the minimal ALIX391–510 fragment was found to specifically interact with this p6 deletion mutant. A parallel analysis of ALIX binding to the late domain p9 from EIAV revealed that p6 and p9, which exhibit distinct ALIX binding motives, likely bind differently to ALIX. Altogether, our data support a model where the C-terminal proline-rich domain of ALIX allows the access of its binding site to p6 by alleviating a conformational constraint resulting from the presence of the central p6 hinge.

    Professional codes of ethics are social contracts among members of a professional group, which aim to instigate, encourage and nurture ethical behaviour and prevent professional misconduct, including research and publication. Despite the existence of codes of ethics, research misconduct remains a serious problem. A survey of codes of ethics from 795 professional organizations from the Illinois Institute of Technology's Codes of Ethics Collection showed that 182 of them (23%) used research integrity and research ethics terminology in their codes, with differences across disciplines: while the terminology was common in professional organizations in social sciences (82%), mental health (71%), sciences (61%), other organizations had no statements (construction trades, fraternal social organizations, real estate) or a few of them (management, media, engineering). A subsample of 158 professional organizations we judged to be directly involved in research significantly more often had statements on research integrity/ethics terminology than the whole sample: an average of 10.4% of organizations with a statement (95% CI = 10.4-23-5%) on any of the 27 research integrity/ethics terms compared to 3.3% (95% CI = 2.1-4.6%), respectively (Porganizations should define research integrity and research ethics issues in their ethics codes and collaborate within and across disciplines to adequately address responsible conduct of research and meet contemporary needs of their communities.

    for health care professionals, compared with the control group. We narrowed the intervention group and no significant differences were found in intention and behavior, except for barriers. Results showed a significant overall difference in barriers between the intervention and the control group (F1=4.128, P=.02). The intervention was used by less than half of the participants and did not improve health care professionals' and patients' cardiovascular risk-reduction behavior. The website was not used intensively because of time and organizational constraints. Professionals in the intervention group experienced higher levels of barriers to encouraging patients, than professionals in the control group. No improvements were detected in the processes of shared decision making and patient self-management. Although participant education level was relatively high and the intervention was pre-tested, it is possible that the way the information was presented could be the reason for low participation and high dropout. Further research embedded in professionals' regular consultations with patients is required with specific emphasis on the processes of dissemination and implementation of innovations in patient-centered care.

    Personal factors, especially attitude, have been implicated in the utilization of health care services, and in access to medical treatment. There is little information on the attitudes of the general public in South Africa towards medications and whether attitudes differ across population groups or among the different users of the health care system. This study aimed to determine the general attitude of a local population to medications, self-care orientation and health professional contact, and whether differences existed between age groups, gender and race groups. METHODS We carried out a randomized, cross-sectional quantitative study via telephonic questionnaire survey (adapted from a previous study) of a sample of 1132 telephone numbers. The setting was the Durban Metropolitan Area, KwaZulu-Natal, South Africa. KEY FINDINGS A total of 500 (44.2%) people responded. The majority had a positive attitude towards medication. An increase in age resulted in increased medication use. Females were more likely than males to use medication and seek professional health care (P = 0.0406). Most of the respondents (86.0%) were self-care-orientated and displayed moderate medication knowledge (46.2%). Some 295 (59.0%) of the 500 respondents had visited a pharmacy within the last 6 months. Conclusions Health care professionals can adopt an informed approach to address the needs of the population with regard to medication, by targeting groups more likely to use medication (females and the older age group). In addition, gaps in medication knowledge were identified which could be used for health-promotion interventions by health care workers.

    Cultural competence (CC) training is widely recognized as a crucial component of the professional development of healthcare providers. There is no study on the effect of Facebook (FB) as a strategy to promote continual learning to enhance CC among students in health professions. To test the effects of cultural competence education using FB as a delivery platform on knowledge, awareness, self-efficacy, and skill related to CC in health students from pre-graduation to licensed professional stages. A randomized controlled trial. We recruited students from professional nursing, pharmacy, and nutrition programs at six medical universities and randomly assigned them to study groups. Between T1 and T2 (months 1-3), the intervention group (IG) received pre-graduation education in CC while the control group (CG) received their regular educational program. Between T2 and T3 (months 6-9), IG received on-the-job education in CC while CG received the regular program. An online self-report questionnaire assessing CC knowledge, awareness, self-efficacy, and skill was analyzed at baseline, 6months, and 12months. Of 180 participants who completed the pretest, 120 (65 IG and 55 CG) completed both follow-ups. Changes over time were mixed; the only statistical difference between groups was an improvement in awareness in IG but not in CG. At 12months, intervention and control participants had different levels of awareness of CC (β=2.56, p<0.001), but other outcomes did not differ between groups. Health profession educators can adopt Facebook as an education delivery platform to offer personalized, social learning incorporating cultural competency curricula into ongoing education and training in rising awareness on CC.

    We report high-resolution Doppler-free two-photon excitation spectroscopy of Xe from the ground state to the 5 p5(P 3 /2 2 ) 6 p [3 /2 ] 2 2 electronic excited state. This is a first step to developing a comagnetometer using polarized 129Xe atoms for planned neutron electric dipole moment measurements at TRIUMF. Narrow linewidth radiation at 252.5 nm produced by a continuous wave laser was built up in an optical cavity to excite the two-photon transition, and the near-infrared emission from the 5 p56 p excited state to the 5 p56 s intermediate electronic state was used to detect the two-photon transition. Hyperfine constants and isotope shift parameters were evaluated and compared with previously reported values. In addition, the detected photon count rate was estimated from the observed intensities.

    2017-01-01

    Full Text Available Professional socialisation of nursing students involves learning skills, attitudes, behaviour and professional roles, largely in the clinical area. During clinical accompaniment and reflective discussions with a group of undergraduate Baccalaureate nursing students in South Africa, students reported negative professional socialisation experiences, primarily in the clinical area. Such experiences could influence the quality of patient care. The objective of this study was to develop and validate guidelines to support professional nurses and educators in the professional socialisation of student nurses. Evidence was generated from an exploration and description of the perceptions of professional nurses regarding their role in the professional socialisation of students, the perceptions of nurse educators regarding the teaching and facilitation of professional socialisation of students, and the socialisation experiences of students. Following a sequential mixed-methods design, qualitative data guided the collection of quantitative data. All data and literature directed the development of these guidelines, which experts reviewed and validated according to a set of criteria. These guidelines focus on the clinical, nursing educational institution environment and values and beliefs of the nursing profession. Facilitation of sound work ethics, professional behaviour, cultural and gender awareness, role modelling and the application of a range of teaching strategies is proposed.

    The aim of this study was to evaluate the effects of the Professional Identity Development Program on the professional identity, job satisfaction and burnout levels of registered nurses. This study was conducted as a quasi-experimental one with 63 nurses working in a university hospital. Data were gathered using the Personal Information Questionnaire, the Professional Self Concept Inventory, Minnesota Job Satisfaction Inventory and the Maslach Burnout Inventory. The Professional Identity Development Program which consists of ten sessions was implemented to the study group once a week. The Program significantly improved the professional identity of the nurses in the study group compared to that of the control group. During the research period, burnout levels significantly decreased in the study group while those of the control group increased. The programme did not create any significant differences in the job satisfaction levels of the nurses. The programme had a positive impact on the professional identity of the nurses. It is recommended that the programme should be implemented in different hospitals with different samples of nurses, and that its effectiveness should be evaluated. © 2014 Wiley Publishing Asia Pty Ltd.

  4. Fasciola spp: Mapping of the MF6 epitope and antigenic analysis of the MF6p/HDM family of heme-binding proteins.

    Directory of Open Access Journals (Sweden)

    Victoria Martínez-Sernández

    Full Text Available MF6p/FhHDM-1 is a small cationic heme-binding protein which is recognized by the monoclonal antibody (mAb MF6, and abundantly present in parenchymal cells and secreted antigens of Fasciola hepatica. Orthologs of this protein (MF6p/HDMs also exist in other causal agents of important foodborne trematodiasis, such as Clonorchis sinensis, Opisthorchis viverrini and Paragonimus westermani. Considering that MF6p/FhHDM-1 is relevant for heme homeostasis in Fasciola and was reported to have immunomodulatory properties, this protein is expected to be a useful target for vaccination. Thus, in this study we mapped the epitope recognized by mAb MF6 and evaluated its antigenicity in sheep. The sequence of the MF6p/FhHDM-1 ortholog from F. gigantica (MF6p/FgHDM-1 was also reported. By means of ELISA inhibitions with overlapping synthetic peptides, we determined that the epitope recognized by mAb MF6 is located within the C-terminal moiety of MF6p/FhHDM-1, which is the most conserved region of MF6p/HDMs. By immunoblotting analysis of parasite extracts and ELISA inhibitions with synthetic peptides we also determined that mAb MF6 reacted with the same intensity with F. hepatica and F. gigantica, and in decreasing order of intensity with C. sinensis, O.viverrini and P. westermani orthologs. On the contrary, mAb MF6 showed no reactivity against Dicrocoelium dendriticum and Schistosoma mansoni. The study of the recognition of peptides covering different regions of MF6p/FhHDM-1 by sera from immunized sheep revealed that the C-terminal moiety is the most antigenic, thus being of potential interest for vaccination. We also demonstrated that the production of antibodies to MF6p/FhHDM-1 in sheep infected by F. hepatica occurs relatively early and follows the same pattern as those produced against L-cathepsins.

    Graphical abstract: - Highlights: • In this work, we prepared Langmuir–Blodgett films of calix[6]arene derivatives. • Then LB films of calixarene compounds were characterized. • Organic vapor sensing properties of prepared LB films were investigated. - Abstract: Organic vapor sensing properties of Langmuir–Blodgett (LB) thin films of p-tert-butyl calix[6]arene and calix[6]arene, and their certain characterization are reported in this work. LB films of these calixarenes have been characterized by contact angle measurement, quartz crystal microbalance (QCM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). QCM system was used for the measurement of sensor response against chloroform, benzene, toluene and ethanol vapors. Forming of stable monolayers was observed at the water surface using surface pressure–area isotherm graph. The results indicate that good quality, uniform LB films can be prepared with a transfer ratio of over 0.95. Due to the adsorption of vapors into the LB film structures; they yield a response to all vapors as of large, fast, and reproducible.

    Probiotics, prebiotics and synbiotics have been suggested as dietary strategies to improve intestinal barrier function. This study aimed to assess the effect of two weeks synbiotic supplementation on intestinal permeability under basal and stressed conditions. Secondary aims were the assessment of two weeks synbiotic supplementation on systemic immune function and gastrointestinal symptoms including defecation pattern. Twenty healthy adults completed a double-blind, controlled, randomized, parallel design study. Groups either received synbiotic (1.5 × 1010 CFU Ecologic® 825 + 10 g fructo-oligosaccharides (FOS P6) per day) or control supplements for two weeks. Intestinal segment specific permeability was assessed non-invasively by oral administration of multiple sugar probes and, subsequently, assessing the excretion of these probes in urine. This test was conducted at baseline and at the end of intervention, in the absence and in the presence of an indomethacin challenge. Indomethacin was applied to induce a compromised gut state. Plasma zonulin, cytokines and chemokines were measured at baseline and at the end of intervention. Gastrointestinal symptoms and stool frequency were recorded at baseline and daily during intervention. Significantly more male subjects were in the synbiotic group compared to the control group (P = 0.025). Indomethacin significantly increased urinary lactulose/rhamnose ratio versus without indomethacin, both in the control group (P = 0.005) and in the synbiotic group (P = 0.017). Urinary sugar recoveries and ratios, plasma levels of zonulin, cytokines and chemokines, and gastrointestinal symptom scores were not significantly different after control or synbiotic intervention. Stool frequency within the synbiotic group was significantly increased during synbiotic intervention compared to baseline (P = 0.039) and higher compared to control intervention (P = 0.045). Two weeks Ecologic® 825/FOS P6 supplementation increased stool frequency

    Numerous reports have described players in professional American sports leagues who have been sidelined with a deep vein thrombosis (DVT) or a pulmonary embolism (PE), but little is known about the clinical implications of these events in professional athletes. To conduct a retrospective review of injury reports from the National Hockey League (NHL), Major League Baseball (MLB), the National Basketball Association (NBA), and the National Football League (NFL) to take a closer look at the incidence of DVT/PE, current treatment approaches, and estimated time to return to play in professional athletes. Descriptive epidemiology study. An online search of all team injury and media reports of DVT/PE in NHL, MLB, NBA, and NFL players available for public record was conducted by use of Google, PubMed, and SPORTDiscus. Searches were conducted using the professional team name combined with blood clot , pulmonary embolism , and deep vein thrombosis . A total of 55 venous thromboembolism (VTE) events were identified from 1999 through 2016 (NHL, n = 22; MLB, n = 16; NFL, n = 12; NBA, n = 5). Nineteen athletes were reported to have an upper extremity DVT, 15 had a lower extremity DVT, 15 had a PE, and 6 had DVT with PE. Six athletes sustained more than 1 VTE. The mean age at time of VTE was 29.3 years (range, 19-42 years). Mean (±SD) time lost from play was 6.7 ± 4.9 months (range, 3 days to career end). Seven athletes did not return to play. Players with upper extremity DVT had a faster return to play (mean ± SD, 4.3 ± 2.7 months) than those with lower extremity DVT (5.9 ± 3.8 months), PE (10.8 ± 6.8 months), or DVT with PE (8.2 ± 2.6 months) ( F = 5.69, P = .002). No significant difference was found regarding time of return to play between sports. VTE in professional athletes led to an average of 6.7 months lost from play. The majority of athletes were able to return to play after a period of anticoagulation or surgery. Those with an upper extremity DVT returned to play

    We analyze Warm Spitzer/Infrared Array Camera observations of the secondary eclipses of three planets, XO-4b, HAT-P-6b, and HAT-P-8b. We measure secondary eclipse amplitudes at 3.6 {mu}m and 4.5 {mu}m for each target. XO-4b exhibits a stronger eclipse depth at 4.5 {mu}m than at 3.6 {mu}m, which is consistent with the presence of a temperature inversion. HAT-P-8b shows a stronger eclipse amplitude at 3.6 {mu}m and is best described by models without a temperature inversion. The eclipse depths of HAT-P-6b can be fitted with models with a small or no temperature inversion. We consider our results in the context of a postulated relationship between stellar activity and temperature inversion and a relationship between irradiation level and planet dayside temperature, as discussed by Knutson et al. and Cowan and Agol, respectively. Our results are consistent with these hypotheses, but do not significantly strengthen them. To measure accurate secondary eclipse central phases, we require accurate ephemerides. We obtain primary transit observations and supplement them with publicly available observations to update the orbital ephemerides of the three planets. Based on the secondary eclipse timing, we set upper boundaries for ecos ({omega}) for HAT-P-6b, HAT-P-8b, and XO-4b and find that the values are consistent with circular orbits.

    Full Text Available Close interaction can be observed between an exoskeleton robot and its wearer. Therefore, appropriate physical human-robot interaction (pHRI should be considered when designing an exoskeleton robot to provide safe and comfortable motion assistance. Different features have been used in recent studies to enhance the pHRI in upper-limb exoskeleton robots. However, less attention has been given to integrating kinematic redundancy into upper-limb exoskeleton robots to improve the pHRI. In this context, this paper proposes a six-degrees-of-freedom (DoF upper-limb exoskeleton robot (6-REXOS for the motion assistance of physically weak individuals. The 6-REXOS uses a kinematically different structure to that of the human lower arm, where the exoskeleton robot is worn. The 6-REXOS has four active DoFs to generate the motion of the human lower arm. Furthermore, two flexible bellow couplings are attached to the wrist and elbow joints to generate two passive DoFs. These couplings not only allow translational motion in wrist and elbow joints but also a redundancy in the robot. Furthermore, the compliance of the flexible coupling contributes to avoiding misalignments between human and robot joint axes. The redundancy in the 6-REXOS is verified based on manipulability index, minimum singular value, condition number and manipulability ellipsoids. The 6-REXOS and a four-DoF exoskeleton robot are compared to verify the manipulation advantage due to the redundancy. The four-DoF exoskeleton robot is designed by excluding the two passive DoFs of the 6-REXOS. In addition, a kinematic model is proposed for the human lower arm to validate the performance of the 6-REXOS. Kinematic analysis and simulations are carried out to validate the 6-REXOS and human-lower-arm model.

    This paper studies the influence of a Scientific Initiation Programme (SIP) on the professional profile of new doctors from a Brazilian university. Evaluate fifty-two new doctors divided into two groups matched by sex, age and academic performance and differing only in participation in the SIP. Professional and socioeconomic data were collected, including schooling of parents; average income before, during and after the medical course; current professional situation; results of exams for civil servant recruitment; and titles and degrees obtained after graduation. Significant differences were found only in civil servant recruitment exam results (p=0.0098) and in income after graduation (p=0.02), which were both higher in the non-SIP group. Only one doctor got a M.Sc. degree after graduation, but many of them in both groups obtained technical titles, and had papers presented at congresses or published. Apparently, taking part in a SIP led to lower income and worse civil servant recruitment exam results. However, this may only reflect a transient phase in a long-term process. New research currently under way will answer this remaining question, now that more time has elapsed since graduation.

    E.O.de Souza

    Full Text Available The activation of competing intracellular pathways has been proposed to explain the reduced training adaptations after concurrent strength and endurance exercises (CE. The present study investigated the acute effects of CE, strength exercises (SE, and endurance exercises (EE on phosphorylated/total ratios of selected AMPK and Akt/mTOR/p70S6K1 pathway proteins in rats. Six animals per exercise group were killed immediately (0 h and 2 h after each exercise mode. In addition, 6 animals in a non-exercised condition (NE were killed on the same day and under the same conditions. The levels of AMPK, phospho-Thr172AMPK (p-AMPK, Akt, phospho-Ser473Akt (p-Akt, p70S6K1, phospho-Thr389-p70S6K1 (p-p70S6K1, mTOR, phospho-Ser2448mTOR (p-mTOR, and phospho-Thr1462-TSC2 (p-TSC2 expression were evaluated by immunoblotting in total plantaris muscle extracts. The only significant difference detected was an increase (i.e., 87% in Akt phosphorylated/total ratio in the CE group 2 h after exercise compared to the NE group (P = 0.002. There were no changes in AMPK, TSC2, mTOR, or p70S6K1 ratios when the exercise modes were compared to the NE condition (P ≥ 0.05. In conclusion, our data suggest that low-intensity and low-volume CE might not blunt the training-induced adaptations, since it did not activate competing intracellular pathways in an acute bout of strength and endurance exercises in rat skeletal muscle.

    Full Text Available Abstract Background Microglia in the central nervous system (CNS were reported to play crucial role in neurodegeneration. Previous studies showed that P2Y6 receptor (P2Y6R mainly contributed to microglia activation and phagocytosis in CNS. However, the level of P2Y6R in Parkinson’s disease (PD patients is unclear. Therefore, we measured the level of P2Y6R in PD patients and speculated whether it could be a potential biomarker for PD. Given on the basis that P2Y6R was higher in PD patients, we further explored the mechanisms underlying P2Y6R in the pathogenesis of PD. Methods We tested the expression level of P2Y6R in the peripheral blood mononuclear cells (PBMCs among 145 PD patients, 170 healthy controls, and 30 multiple system atrophy (MSA patients. We also used a lipopolysaccharide (LPS-stimulated microglial cell culture model to investigate (i the effects of LPS on P2Y6R expression with western blot and RT-PCR, (ii the effects of LPS on UDP expression using HPLC, (iii the effects of UDP/P2Y6R signaling on cytokine expression using western blot, RT-PCR, and ELISA, and (iv the signaling pathways activated by the P2Y6R involved in the neuroinflammation. Results Expression levels of P2Y6R in PD patients were higher than healthy controls and MSA patients. P2Y6R could be a good biomarker of PD. P2Y6R was also upregulated in LPS-treated BV-2 cells and involved in proinflammatory cytokine release through an autocrine loop based on LPS-triggered UDP secretion and accelerated neuroinflammatory responses through the ERK1/2 pathway. Importantly, blocking UDP/P2Y6R signaling could reverse these pathological processes. Conclusions P2Y6R may be a potential clinical biomarker of PD. Blocking P2Y6R may be a potential therapeutic approach to the treatment of PD patients through inhibition of microglia-activated neuroinflammation.

    Eldecalcitol (ELD), a 2β-hydroxypropyloxy derivative of 1α,25(OH)2D3, is a potent inhibitor of bone resorption that has demonstrated a greater effect at reducing the risk of fracture in osteoporotic patients than alfacalcidol (ALF). In the present study, we used the senescence-accelerated mouse strain P6 (SAM/P6), which has low bone mass caused by osteoblast dysfunction, to evaluate the effect of ELD on cortical bone in comparison with ALF. Four-month-old SAM/P6 mice were given either ELD (0.025 or 0.05μg/kg) or ALF (0.2 or 0.4μg/kg) by oral gavage 5 times/week for 6 weeks. Both ELD and ALF increased serum calcium (Ca) in a dose-dependent manner. Serum Ca levels in the ELD 0.05μg/kg group were comparable to those of the ALF 0.2μg/kg group. ELD 0.05μg/kg significantly improved the bone biomechanical properties of the femur compared with the vehicle control group (pBone histomorphometry revealed that in the femoral endocortical surface, the suppression of bone resorption parameters (N.Oc/BS) and bone formation parameters (MS/BS) by ELD (0.05μg/kg) was greater than that by ALF (0.2μg/kg). In contrast, in the femoral periosteal surface, ELD 0.05μg/kg significantly increased bone formation parameters (BFR/BS, MS/BS) compared with the vehicle control group (pbone not only by inhibiting endocortical bone resorption but also by stimulating the periosteal bone formation in SAM/P6 mice.

    Although health care professionals may be assumed to make healthier lifestyle choices and have better health outcomes than others because of their greater health literacy, little is known about how actual health outcomes of health care professionals compare with those of the overall population. We analyzed how trends in obesity, diabetes, hypertension, and coronary artery disease prevalence as well as several health behaviors (smoking, alcohol use, and exercise) varied between health care professionals and the general US population from 2002 to 2013, using nationally representative data collected by the National Health Interview Survey. We estimated multivariate logistic regressions of each disease and behavior adjusted for age, race, sex, geographic region, and year. Although rates of obesity, diabetes, and hypertension were lower among health care professionals compared with the overall population, disease was still common among health care professionals and increased over time at a rate similar to that of the overall population. For example, obesity prevalence was lower among health care professionals but increased similarly from 2002 to 2013 (health care professionals, 20.5% in 2002 to 22.1% in 2013; other occupations, 28.4% to 31.7%; P=.64 for difference in trend). Diabetes prevalence was modestly lower among health care professionals but increased at a similar rate (health care professionals, 7.4% in 2005 to 8.6% in 2013; other occupations, 8.7% to 9.9%; P=.67 for difference in trend). Similar patterns were noted in hypertension. Coronary artery disease prevalence declined over time among health care professionals but increased for others. Health care professionals reported better health behaviors than others in smoking and physical activity but not in moderate to heavy alcohol use.

    Full Text Available Let p be a prime. It is shown that an automorphism α of an abelian p-group A lifts to any abelian p-group of which A is a homomorphic image if and only if α=π idA, with π an invertible p-adic integer. It is also shown that if A is torsion group or torsion-free p-divisible group, then idA and −idA are the only automorphisms of A which possess the lifting property in the category of abelian groups.

    Health knowledge develops fast and includes a lot of ambiguous or tentative information. In their daily routine, both health care students and professionals continuously have to make judgments about the viability of health knowledge. People's epistemological beliefs (EBs) and their therapeutic health concepts are factors that influence how they deal with health knowledge. However, very little is known about the occurrence of these factors at different stages of people's career. The present study examines the EBs and therapeutic health concepts of physiotherapy students in their vocational training and the EBs and therapeutic health concepts of professionals. In a cross-sectional study physiotherapy students and professional physiotherapists filled in a questionnaire that measured their personal EBs about physiotherapy and medicine, as well as their biomedical and biopsychosocial therapeutic health concepts. We compared the participants' EBs regarding both knowledge domains, and their therapeutic health concepts using paired samples t-tests. We also examined the differences between first-year students, advanced students, and professionals regarding their EBs and their therapeutic health concepts using ANOVAs. Eighty-three students and 84 professionals participated in this study, 114/167 (68%) participants were female. EBs as well as therapeutic health concepts differed depending upon the participants' training status. Professionals had more sophisticated EBs than students regarding both knowledge in physiotherapy (F(2, 164) = 6.74, P = 0.002, η(2)(p) = 0.08) and knowledge in medicine (F(2, 164) = 5.93, P = 0.003, η(2)(p) = 0.07). In addition, high values in a biopsychosocial therapeutic health concept already occurred in an early phase of training (F(2, 164) = 5.39, P = 0.005, η(2)(p) = 0.06), whereas increased values in a biomedical concept did not occur until people's professional life (F(2, 164) = 10.99, P students as

    To assess the social skills of health care professionals in the emergency and critical care units of the regional hospital Vega Baja and analyze the association between a series of sociodemographic and professionals variables and social skills. A cross-sectional, descriptive study. Two evaluation tools were used. These included a sociodemographic and professional variables questionnaire, and the Elena Gismero's Social Skills Scale (SSS). A response rate of 82.6% was obtained. Considering the standards made by the author in SSS validation, it can be seen that the sample has obtained a medium-high score in each one of the aspects. Significant differences have been found when considering the sociodemographic variable gender as an independent variable with the complete score of SSS (F=6.555; p=0.013), and with the scale dimensions, self-expression in social situations (F=4.468; p=0.039) and making a demand (F=7.982; p=0.007). In each one of the SSS dimensions, the sample has obtained a slightly higher score than the standard sample and it within the 50-69 percentile. This indicates the existence of a medium-high level of Social Skill. The doctors score higher than the nurses, although these differences are not statistically significant.

    The effect of the addition of a macrocyclic host (H) such as p-sulfonatocalix[6]arene (C6S), native and modified cyclodextrins (CDs), on the fluorescence of benzoimidazolic fungicides (P), like Benomyl (BY) and Carbendazim (CZ), has been studied. The fluorescence of BY in water at pH 1.000 and 25.0 deg. C was increased in the presence of C6S, αCD and hydroxypropyl-β-CD (HPCD). The association constants determined by fluorescence enhancement showed weak interactions (K A ∼ 10 1 to 10 2 M -1 ) between the fungicide with both CDs, whereas they were stronger with C6S (K A ∼ 10 5 M -1 ). Molecular recognition of BY for C6S was mainly attributed to electrostatic interactions, and for CDs to the hydrophobic effect and hydrogen bond formation. On the other hand, the fluorescent behaviour of CZ in the presence of C6S at pH 6.994 was interpreted as the formation of two complexes with 1:1 (P:H) and 1:2 (P:H 2 ) stoichiometry, the latter being less fluorescent than the free analyte. Relative fluorescence quantum yield ratios between the complexed and free BY (φ P:H /φ P ) were 2.00 ± 0.05, 1.40 ± 0.03 and 2.8 ± 0.4 for C6S, αCD and HPCD, respectively. The analytical parameters improved in the presence of C6S and CDs. The best limit of detection (L D , ng mL -1 ) was 17.4 ± 0.8 with HPCD. The proposed method with C6S and HPCD was successfully applied to fortified samples of tap water and orange flesh extract with good recoveries (91-106%) and R.S.D. (≤2%) by triplicate analysis. The method is rapid, direct and simple and needs no previous degradation or derivatization reaction

    A C6-carboxylated curdlan (C6-Cc) obtained from 4-acetamido-TEMPO-mediated oxidation of curdlan was used both as a reducing and stabilizing agent for green synthesis of pH-responsive AuNPs, which was carried out by controlling the pH of the C6-Cc solution at a high temperature (100°C). C6-Cc presented a semi-flexible random coil chain in the aqueous medium at pH 5.5 and became more expanded and rigid in alkaline conditions (pH 7.1-12.0), though the primary chemical structure of C6-Cc was virtually unchanged with the pH variation. The AuNPs prepared with C6-Cc at various pHs were characterized by various instrumental measurements. The shapes and sizes of AuNPs were found to be strongly dependent on the pH of the C6-Cc solution. The C6-Cc-decorated AuNPs exhibited a more well-dispersed spherical morphology with smaller particle sizes under alkaline conditions (pH 7.1-12.0). Through this study, a facile, simple, and green method has been demonstrated for preparation of stimuli-sensitive AuNPs using biocompatible polyanionic polysaccharides. Copyright © 2017 Elsevier B.V.

    Accurate predictions of pKa values of titratable groups require taking into account all relevant processes associated with the ionization/deionization. Frequently, however, the ionization does not involve significant structural changes and the dominating effects are purely electrostatic in origin allowing accurate predictions to be made based on the electrostatic energy difference between ionized and neutral forms alone using a static structure. On another hand, if the change of the charge state is accompanied by a structural reorganization of the target protein, then the relevant conformational changes have to be taken into account in the pKa calculations. Here we report a hybrid approach that first predicts the titratable groups, which ionization is expected to cause conformational changes, termed “problematic” residues, then applies a special protocol on them, while the rest of the pKa’s are predicted with rigid backbone approach as implemented in multi-conformation continuum electrostatics (MCCE) method. The backbone representative conformations for “problematic” groups are generated with either molecular dynamics simulations with charged and uncharged amino acid or with ab-initio local segment modeling. The corresponding ensembles are then used to calculate the pKa of the “problematic” residues and then the results are averaged. PMID:21744395

    While 10% of the general population is left-handed, 27% of professional baseball pitchers are left-handed. Biomechanical differences between left- and right-handed college pitchers have been previously reported, but these differences have yet to be examined at the professional level. Therefore, the purpose of this study was to compare pitching biomechanics between left- and right-handed professional pitchers. It was hypothesised that there would be significant kinematic and kinetic differences between these two groups. Pitching biomechanics were collected on 96 left-handed pitchers and a group of 96 right-handed pitchers matched for age, height, mass and ball velocity. Student t-tests were used to identify kinematic and kinetic differences (p different between the groups. Landing position of the stride foot, trunk separation at foot contact, maximum shoulder external rotation and trunk forward tilt at ball release were all significantly greater in right-handed pitchers. The magnitude of the statistical differences found were small and not consistent with differences in the two previous, smaller studies. Thus, the differences found may be of minimal practical significance and mechanics can be taught the same to all pitchers, regardless of throwing hand.

    In the university context, assessing students' attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students' attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 months. Control group performed a public exposition of a clinical case about professional ethics. By contrast, an 8-month blended-learning programme regarding professional ethics was worked out for experimental group. An online syllabus and online activities were elaborated, while face-to-face active participation techniques were performed to discuss ethical issues. Students' attitudes, knowledge and opinions towards learning professional ethics were assessed. Ethical considerations: The study was approved by the University Ethic Committee of Human Research and followed the ethical principles according to the Declaration of Helsinki. After the programme, attitudes and knowledge towards learning professional ethics of experimental group students significantly improved, while no differences were observed in control group. Moreover, opinions reported an adequate extension of themes and temporization, importance of clinical practices and interest of topics. Case study method and role playing were considered as the most helpful techniques. The blended-learning programme proposed, based on professional ethics and related to clinical practices, improves physiotherapy students' attitudes, knowledge and opinions towards learning professional ethics.

    Full Text Available In this work we are consider a possibility to create schemes of open key distribution in the groups meeting conditions C(3-T(6. Our constructions use the following algorithms.1. The algorithm that solves the membership problem for cyclic subgroups, also known as the discrete logarithm problem.2. The algorithm that solves the word problem in this class of groups.Our approach is based on the geometric methods of combinatorial group theory (the method of diagrams in groups.In a cryptographic scheme based on the open key distribution one-way functions are used, i.e. functions direct calculation of which must be much easier than that of the inverse one. Our task was to construct a one-way function using groups with small cancelation conditions C(3-T(6 and to compare the calculation complexity of this function with the calculation complexity of its inverse.P.W. Shor has shown in the paper that there exists a polynomial algorithm that can be implemented in a quantum computer to solve the discrete logarithm problem in the groups of units of finite fields and the rings of congruences mod n. This stimulated a series of investigations trying to find alternative complicated mathematical problems that can be used for construction of new asymmetric cryptosystems. For example, open key distribution systems based on the conjugacy problem in matrix groups and the braid groups were proposed.In the other papers the constructions used the discrete logarithm problem in the groups of inner automorphisms of semi-direct products of SL(2,Z and Zp and GL(2,Zp and Zp. groups. The paper of E. Sakalauskas, P. Tvarijonas, A. Raulinaitis proposed a scheme that uses a composition of two problems of group theory, namely the conjugacy problem and the discrete logarithm problem.Our results show that the scheme that we propose is of polynomial complexity. Therefore its security is not sufficient for further applications in communications. However the security can be improved

    In a previously reported panel study [Speedling et al. (1981). Int. J. Nurs. Stud. 18, 217-225], 180 Registered Nurses, three-quarters new graduates, were given questionnaires at time of hire and a year later. Using the panel study data, relationships among bureaucratic-professional role conception, actual situation and role discrepancy, and importance of job factors, job satisfaction and alienation, as well as age and length of stay at termination for time of hire only, are explored in this follow-up report. Mean bureaucratic actual situation (t = -5.18, P less than 0.001), bureaucratic role discrepancy (t = -2.77, P less than 0.01) and alienation (t = -2.36, P less than 0.05) increased, while professional actual situation (t = 3.39, P less than 0.01) and importance of job factors (t = 2.33, P less than 0.05) decreased during this first year of employment. In correlational analysis, at the time of hiring relationships were found between numerous variables, including: bureaucratic role conception with alienation (r = 0.17, P less than 0.05); bureaucratic actual situation with alienation (r = 0.19, P less than 0.05); professional role conception with alienation (r = -0.20, P less than 0.05) and with job satisfaction (r = -0.35, P less than 0.001); professional actual situation with job satisfaction (r = -0.19, P less than 0.05); and professional role discrepancy with job satisfaction (r = 0.23, P less than 0.01). A year after hiring, many relationships were found, including professional actual situation with job satisfaction (r = 0.26, P less than 0.05) and alienation with job satisfaction (r = -0.33, P less than 0.01). In stepwise regression analysis, age accounted for 8% of the variance in the importance of job factors (P less than 0.05), professional role conception for 28% of the variance in job satisfaction (P less than 0.001) at time of hire. A year after hiring, alienation and job satisfaction accounted for 12% of the variance in each other (P less than 0

    The aim of the present study was to compare results of non-dental (conventional) and dental colour discrimination tests (customized, shade guide test), to evaluate influence of profession, gender and age of colour normal dentists and laboratory technicians on colour discrimination results and to evaluate results of colour deficient laypersons. A total of 36 colour normal dental professionals, all volunteers were divided into two groups consisting of 18 participants each: dentists (DDS) and laboratory technicians (CDT). In addition, a group 15 colour deficient males also volunteered (CDP). Colour discrimination was examined using Farnsworth-Munsell 100 Hue Test and total error scores (TES) were calculated. Participants performed a dentistry related colour discrimination test by matching 26 pairs of shade tabs. Shade guide scores (3DS) were calculated. These tests were performed under the controlled conditions of a viewing booth. Mean values and standard deviations were determined. ANOVA, Mann-Whitney test, t-test and Pearson's correlation coefficient (r) were used for result analysis. TES and 3DS were correlated for colour normal observers, r = 0.47 (p gender and age were recorded. TES of 159 (83) and 3DS of 6.7 (2.7) were recorded for colour deficient laypersons. Based on TES, 33% of colour deficient laypersons had average discrimination, whilst 67% had low discrimination. Within the limitation of this study, it was concluded that results of non-dental and dental colour discrimination tests were correlated, and that profession (DDS/CDT), gender and age gender did not influence colour discrimination of colour normal participants. Although colour and appearance of dental restorations are of paramount importance for the aesthetic outcome, colour vision of dental professionals is not routinely tested. This paper validates and recommends the usage of dental shade guides for a simple, affordable and understandable testing of colour vision, either as a sole test or

    Collaboration between general practice and mental health care has been recognised as necessary to provide good quality healthcare services to people with mental health problems. Several studies indicate that collaboration often is poor, with the result that patient' needs for coordinated services are not sufficiently met, and that resources are inefficiently used. An increasing number of mental health care workers should improve mental health services, but may complicate collaboration and coordination between mental health workers and other professionals in the treatment chain. The aim of this qualitative study is to investigate strengths and weaknesses in today's collaboration, and to suggest improvements in the interaction between General Practitioners (GPs) and specialised mental health service. This paper presents a qualitative focus group study with data drawn from six groups and eight group sessions with 28 health professionals (10 GPs, 12 nurses, and 6 physicians doing post-doctoral training in psychiatry), all working in the same region and assumed to make professional contact with each other. GPs and mental health professionals shared each others expressions of strengths, weaknesses and suggestions for improvement in today's collaboration. Strengths in today's collaboration were related to common consultations between GPs and mental health professionals, and when GPs were able to receive advice about diagnostic treatment dilemmas. Weaknesses were related to the GPs' possibility to meet mental health professionals, and lack of mutual knowledge in mental health services. The results describe experiences and importance of interpersonal knowledge, mutual accessibility and familiarity with existing systems and resources.

    Introduction Polymorphic variants in the 5p15, 6p12, 6p21, and 15q25 loci were demonstrated to potentially contribute to lung cancer carcinogenesis. Therefore, this study was performed to assess the role of those variants in non-small cell lung cancer (NSCLC) risk and prognosis in a Portuguese population. Materials and Methods Blood from patients with NSCLC was prospectively collected. To perform an association study, DNA from these patients and healthy controls were genotyped for a panel of 19 SNPs using a Sequenom® MassARRAY platform. Kaplan-Meier curves were used to assess the overall survival (OS) and progression-free survival (PFS). Results One hundred and forty-four patients with NSCLC were successfully consecutively genotyped for the 19 SNPs. One SNP was associated with NSCLC risk: rs9295740 G/A. Two SNPs were associated with non-squamous histology: rs3024994 (VEGF intron 2) T/C and rs401681 C/T. Three SNPs were associated with response rate: rs3025035 (VEGF intron 7) C/T, rs833061 (VEGF –460) C/T and rs9295740 G/A. One SNP demonstrated an influence on PFS: rs401681 C/T at 5p15, p = 0.021. Four SNPs demonstrated an influence on OS: rs2010963 (VEGF +405 G/C), p = 0.042; rs3025010 (VEGF intron 5 C/T), p = 0.047; rs401681 C/T at 5p15, p = 0.046; and rs31489 C/A at 5p15, p = 0.029. Conclusions Our study suggests that SNPs in the 6p12, 6p21, and 5p15 loci may serve as risk, predictive and prognostic NSCLC biomarkers. In the future, SNPs identified in the genomes of patients may improve NSCLC screening strategies and therapeutic management as well. PMID:24039754

    In Sweden, as well as in most industrialised countries, an increasing older population is expected to create a growing demand for health care staff. Previous studies have pointed to lack of proficient medical and nursing staff specialised in geriatric care, which poses serious threats to the care of a vulnerable population. At the same time, there are studies describing elderly care as a low-status career choice, attracting neither nurses nor student nurses. Judging from previous research it was deemed important to explore how nurses in elderly care perceive their work, thus possibly provide vital knowledge that can guide nurse educators and unit managers as a means to promote a career in elderly care. The aim of the present study was to illuminate how nurses, working in nursing homes and home-based care, perceived their professional work. This was a qualitative study using focus groups. 30 registered nurses in seven focus groups were interviewed. The participants worked in nursing homes and home-based care for the elderly in rural areas and in a larger city in southern Sweden. The interviews were analysed in line with the tradition of naturalistic inquiry. Our findings illustrate how nurses working in elderly care perceived their professional work as holistic and respectful nursing. Three categories of professional work emerged during analysis: (1) establishing long-term relationships, (2) nursing beyond technical skills, and (3) balancing independence and a sense of loneliness. The findings are important as they represent positive alternatives to the somewhat prevailing view on elderly care as depressing and undemanding. Nurse educators might use the key aspects as good examples, thus influencing student nurses' attitudes towards elderly care in a positive way. Elderly care agencies might find them helpful when recruiting and retaining nurses to a much needed area. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts. © 2015 John Wiley & Sons A/S.

    DNA methylation of the cytokine genes may play a role in the pathogenesis of periodontitis. The aim of this study is to evaluate whether the alteration of interleukin-6 (IL-6) gene promoter methylation in the gingival tissue (GT) and peripheral blood (PB) is unique to chronic periodontitis (CP). DNA isolated from the GT and PB of 25 patients with (CP) and 20 healthy controls (H) was modified with sodium bisulfite and analyzed for IL-6 promoter methylation with direct sequencing. The levels of IL-6 mRNA and serum IL-6 protein were evaluated by a quantitative reverse transcription polymerase chain reaction and an enzyme-linked immunosorbent assay. The CP group showed that the overall methylation rates of IL-6 promoter that contained 19 cytosine-guanine dinucleotide (CpG) motifs were significantly decreased in GT in comparison to PB (p<0.001), which was significantly negatively correlated with the probing depth (p=0.003). The GT and PB of the H group displayed similar overall methylation rates. No significant difference was observed in the methylation rates at each CpG in GT in comparison to the PB in both groups. The levels of IL-6 mRNA in the GT and PB and serum IL-6 of the two groups were comparable. The ratio of IL-6 mRNA in the GT relative to the PB was significantly higher in the CP group than in the H group (p=0.03). The increased expression of IL-6 gene transcription may be related to IL-6 promoter hypomethylation in the GT from CP patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective. To determine the benefit of pharmacy work experience on the development of student pharmacists' professional identity. Methods. Students in all four professional years were surveyed using a validated Professional Self-identity Questionnaire (PSIQ). They were also asked about pharmacy experience prior to matriculation and their performance on Drug Information tests given midway through the P1 year and at the beginning of the P3 year. PSIQ responses and test results were compared based on pharmacy experience. Results. The PSIQ was completed by 293 student pharmacists, for a 67% response rate, with 76% of respondents reporting pharmacy experience prior to matriculation. Statistically higher scores on responses to 6 of the 9 PSIQ Likert-type items were observed from students in the first professional year for those with pharmacy experience; however, only one item in the second year showed differences with none in the third and fourth years. No impact of experience was observed on Top 100 or Top 300 grades. Conclusion. Pre-matriculation pharmacy experience may increase development of professional identity early in the student experience but may have little impact on academic readiness. Schools and colleges of pharmacy hoping to recruit students with an early sense of professional identity should consider adding such experience to their admissions requirements.

    Exclusive breastfeeding rates remain low in Kenya and determinants influencing mothers' practice are documented. Little is known about factors underlying health professionals' intention to support mothers to continue exclusive breastfeeding. Effective behavior modification requires designing interventions at multiple levels of influence, informed by theory-based research to identify relevant determinants. To identify salient beliefs held by health professionals about support of mothers to exclusively breastfeed for 6 months and to explore definitions of the term support. This qualitative study was conducted in 6 public health facilities in Nairobi, Kenya. We used open-ended questions based on the reasoned action approach to elicit salient consequences, referents, and circumstances perceived by 15 health professionals about support for mothers to exclusively breastfeed for 6 months. The most frequently mentioned consequences were healthier babies (87%) and reduced childhood ailments (67%). The main disadvantage was human immunodeficiency virus transmission through breast milk (33%). Colleagues (80%) and managers (67%) were perceived as approving referents, whereas some mothers/couples (40%) and the breast milk substitute industry (20%) were perceived as disapproving. Facilitating circumstances included lighter workload, better training, and more time. Definitions of support were varied and included giving information and demonstrating positioning and attachment techniques. Overall, health professionals perceived positive consequences toward supporting exclusive breastfeeding continuation and identified a number of approving referents. However, they reported challenging circumstances in the work environment, which managers need to address to help health professionals provide the support needed by Kenyan mothers to continue exclusive breastfeeding. © The Author(s) 2016.

    Practice Based Small Group Learning (PBSGL) is an established learning resource for primary care clinicians in Scotland and is used by one-third of general practitioners (GPs). Scottish Government and UK professional bodies have called for GPs and pharmacists to work more closely together to improve care. To gain GPs' and pharmacists' perceptions and experiences of learning together in an inter-professional PBSGL pilot. Qualitative research methods involving established GP PBSGL groups in NHS Scotland recruiting one or two pharmacists to join them. A grounded theory method was used. GPs were interviewed in focus groups by a fellow GP, and pharmacists were interviewed individually by two researchers, neither being a GP or a pharmacist. Interviews were audio-recorded, transcribed and analysed using grounded theory methods. Data saturation was achieved and confirmed. Three themes were identified: GPs' and pharmacists' perceptions and experiences of inter-professional learning; Inter-professional relationships and team-working; Group identity and purpose of existing GP groups. Pharmacists were welcomed into GP groups and both professions valued inter-professional PBSGL learning. Participants learned from each other and both professions gained a wider perspective of the NHS and of each others' roles in the organisation. Inter-professional relationships, communication and team-working were strengthened and professionals regarded each other as peers and friends.

    The aim of this study was to analyse the efficiency of muscular activity in the trunk stabilisation of professional volleyball players compared to a group of amateur hobby players. The results were compared amongst the groups as well as with a reference group consisting of asymptomatic individuals. The question to be answered was whether or not professional volleyball players possess a characteristic strength profile in their trunk musculature and if differences exist with regard to the individuals' competitive playing level. In this comparative study 12 professional volleyball players (German Bundesliga) and 18 non-professional volleyball players were analysed with regard to their isometric strength profile in all three planes. The reference group was provided by the Proxomed company, which had previously analysed healthy untrained individuals (n = 1045) of various age groups. A sports-specific profile for the musculature of volleyball players revealed a significant reduction in the flexion and rotation strength as well as a well-developed lateral flexion strength (highly significant when compared to the reference group). With reference to the level played, better strength values in flexion and lateral flexion were found among the professional athletes. Professional volleyball players present with a characteristic trunk musculature strength profile. A detailed analysis of the muscle strength of the spine as part of a sports medicine work-up could prove helpful in preventing injuries and overuse problems in professional and hobby volleyball players.

    Full Text Available Serum creatine kinase (CK concentration has been widely used as an indicator of skeletal muscle damage in sports. However, there are no longitunal studies on post-game CK kinetics in Soccer during a competitive season. The aim of this study was to evaluate serum CK kinetics in professional Soccer players at different post-game times during a competitive season without training interruption. Seventeen professional soccer players (age: 22.2±3.1 years, height: 179±6.0 cm, body fat percentage: 9.5±1.1, and 67.0±3.5 mL O2/kg/min were evaluated over a period of 3 months of the national championship. Serum CK concentration was measured before the beginning of the season (baseline and at four different times after a soccer game (post-1: 12-20 h, post-2: 36-48 h, post-3: 60-65 h, and post-4: 90-110 h. Plasma CK concentrations were higher at all times when compared to baseline (p<0.05. Post-2 CK concentration was lower than post-1 and higher than post-3 and -4 (p<0.05, with no significant differences between post-3 and post-4. In conclusion, serum CK kinetics was influenced by the training routine of the soccer players, with a peak between 12 and 20 h after the game, returning to normal within 60-65 h. This procedure can be used to monitor the recovery state of athletes and game and training intensities.

    Species A rotaviruses are highly diverse and impose a substantial burden to human and animal health. Interspecies transmission between livestock, domestic animals and humans is commonly observed, but spread of animal-like rotaviruses within the human population is limited. During the continued monitoring of rotavirus strains in Germany, an unusual G6P[9] rotavirus strain was detected in feces of a child. The complete rotavirus coding sequences revealed a unique G6-P[9]-I2-R2-C2-M2-A3-N2-T3-E2-H3 genotype constellation. The virus was phylogenetically related to feline G3P[9] strains and other human G6P[9] rotaviruses of presumable zoonotic origin. Analysis of primer binding sites of G6 specific genotyping revealed further evidence of a G6P[9] feline reservoir. Moreover, substantial deficits of conventional semi-nested PCR genotyping approaches in detecting contemporary G6P[9] were revealed. Rotavirus strain GER29-14 most likely resulted from a direct or recent interspecies transmission from a cat to human. Further studies could assess nucleic acid sequences and genotype constellations of feline rotavirus to confirm the likely feline origin of sporadic human G6P[9] strains.

    Listening to loud music may be connected to addictive behavior possibly leading to damaging effects on the cochlea. We hypothesized that members of non-professional pop/rock bands with regular exposure to loud music are more likely to show an addictive-like behavior for loud music than matched control subjects. Fifty non-professional musicians and 50 matched control subjects were asked to complete the Northeastern Music Listening Survey (NEMLS) with two basic components. The first comprises an adaptation of the validated Michigan Alcohol Screening Test (MAST) to study the addictive-like behavior towards loud music. The second comprises the criteria outlined by the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Society for the diagnosis of substance dependence. The NEMLS was scored using the same point system as used in the MAST. The DSM-IV criteria for substance dependence were met by nine of the musician group and by one control subject. Seven of these nine musicians also had a positive NEMLS score. Traits of addictive-like behavior to loud music were detected more often in members of nonprofessional pop/rock bands than in control subjects.

    The literature on team and inter-professional care practice describes numerous barriers to the institutionalization of inter-professional healthcare. Responses to slow institutionalization of inter-professional healthcare practice have failed to describe change variables and to identify change agents relevant to inter-professional healthcare practice. The purpose of this paper is to (1) describe individual and organizational level barriers to collaborative practice in healthcare; (2) identify change variables relevant to the institutionalization of inter-professional practice at individual and organizational levels of analysis; and (3) identify human resource professionals as change agents and describe how the strategic use of the human resource function could transform individual and organizational level change variables and therefore facilitate the healthcare system's shift toward inter-professional practice. A proposed program of institutionalization includes the following components: a strategic plan to align human resource functions with organizational level inter-professional healthcare strategies, activities to enhance professional competencies and the organizational position of human resource personnel, activities to integrate inter-professional healthcare practices into the daily routines of institutional and individual providers, activities to stand up health provider champions as permanent leaders of inter-professional teams with human resource professionals as consultants and activities to bring all key players to the table including health providers.

    The interactions of protein components of the xenobiotic-metabolizing cytochrome P450 system, CYP6A1, P450 reductase, and cytochrome b5 from the house fly (Musca domestica) have been characterized. CYP6A1 activity is determined by the concentration of the CYP6A1-P450 reductase complex, regardless of which protein is present in excess. Both holo- and apo-b5 stimulated CYP6A1 heptachlor epoxidase and steroid hydroxylase activities and influenced the regioselectivity of testosterone hydroxylatio...

    Full Text Available IL-6 is a multifaceted pleiotropic cytokine, which is produced by a variety of cell types and targets different cells and tissues. In physiological conditions, IL-6 can be locally and transiently produced by skeletal muscle and plays an important role in muscle homeostasis. Circulating IL-6 levels are normally very low or undetectable but are dramatically increased in several pathologic conditions. In this study, we aimed to define the potential molecular mechanisms underlying the effects of IL-6 on myogenic program. We explored the molecular mechanisms through which exogenous IL-6, or the conditioned medium from the murine C-26 adenocarcinoma cells (a cellular model that secretes high levels of IL-6 and induces cancer cachexia in mice, interferes with the myogenic program. Our study revealed that IL-6 induces the activation of the Stat3 signaling and promotes the downmodulation of the p90RSK/eEF2 and mTOR/p70S6K axes, while it does not affect the activation of AKT. We thus identified potential molecular mediators of the inhibitory effects of IL-6 on myogenic program.

    Blood transfusion is one of the major areas where serious clinical consequences, even death, related to patient misidentification can occur. In the UK, healthcare professional compliance with pre-transfusion checking procedures which help to prevent misidentification errors is poor. Involving patients at a number of stages in the transfusion pathway could help prevent the occurrence of these incidents. To investigate patients' willingness to be involved and healthcare professionals' willingness to support patient involvement in pre-transfusion checking behaviours. A cross-sectional design was employed assessing willingness to participate in pre-transfusion checking behaviours (patient survey) and willingness to support patient involvement (healthcare professional survey) on a scale of 1-7. One hundred and ten patients who had received a transfusion aged between 18 and 93 (60 male) and 123 healthcare professionals (doctors, nurses and midwives) involved in giving blood transfusions to patients. Mean scores for patients' willingness to participate in safety-relevant transfusion behaviours and healthcare professionals' willingness to support patient involvement ranged from 4.96-6.27 to 4.53-6.66, respectively. Both groups perceived it most acceptable for patients to help prevent errors or omissions relating to their hospital identification wristband. Neither prior experience of receiving a blood transfusion nor professional role of healthcare staff had an effect on attitudes towards patient participation. Overall, both patients and healthcare professionals view patient involvement in transfusion-related behaviours quite favourably and appear in agreement regarding the behaviours patients should adopt an active role in. Further work is needed to determine the effectiveness of this approach to improve transfusion safety. © 2012 The Authors. Transfusion Medicine © 2012 British Blood Transfusion Society.

    subject to validation in the process of research. The validation of the proposed principles was carried out using the example of an advanced training program “Design and Development of Electronic Training Courses”, implemented by ANO “eNano” by an expert survey, and based on a statistically significant sample.Results. As the result of research, the authors obtained confirmation of the effectiveness of the proposed methodological principles, using the expert survey method by questioning 35 participants who had completed the above-mentioned advanced training program in a completely distant format. This total set was formed from three flows, within which the trainees were divided into groups of 3–4 people and themselves moderated the roles within the subgroups when performing group (team assignments. Particular value in this sample is that all trainees have higher educational level and all they are employees and lecturers of five Russian universities (Samara State University, Perm National Research Polytechnic University, P.G.Demidov Yaroslavl State University, Kazan National Research Technological University, National University of Science and Technology, Moscow, among them – 6 professors, doctors of sciences, 18 associate professors, candidates of sciences, 2 deans, 2 heads of departments, 4 directors of distance learning centers. Conclusion. The authors hope to continue this research, extending it to professional retraining programs and masters’ programs in the full long distance format.

    The use of games as an educational strategy has the potential to improve health professionals' performance (e.g. adherence to standards of care) through improving their knowledge, skills and attitudes. The objective was to assess the effect of educational games on health professionals' performance, knowledge, skills, attitude and satisfaction, and on patient outcomes. We used a comprehensive search strategy including an electronic search of the following databases: DARE, EPOC register, CENTRAL, MEDLINE, EMBASE, CINAHL, AMED, ERIC, and Dissertation Abstracts Online (search date: January 2007). We also screened the reference list of included studies and relevant reviews, contact authors of relevant papers and reviews, and searched ISI Web of Science for papers citing studies included in the review We included randomized controlled trials (RCT), controlled clinical trials (CCT), controlled before and after (CBA) and interrupted time-series analysis (ITS). Study participants were qualified health professionals or in postgraduate training. The intervention was an educational game with "a form of competitive activity or sport played according to rules". Using a standardized data form we extracted data on methodological quality, participants, interventions and outcomes of interest that included patient outcomes, professional behaviour (process of care outcomes), and professional's knowledge, skills, attitude and satisfaction. The search strategy identified 1156 citations. Out of 55 potentially eligible citations, we included one RCT. The methodological quality was fair. The game, used as a reinforcement technique, was based on the television game show "Family Feud" and focused on infection control. The study did not assess any patient or process of care outcomes. The group that was randomized to the game had statistically higher scores on the knowledge test (P = 0.02). The findings of this systematic review do not confirm nor refute the utility of games as a teaching

    Full Text Available Introduction: Dental caries is one of the most common conditions affecting the general health of children. The present study was carried out among school children of Kathmandu valley to determine the prevalence of dental caries in two age groups. Methods: The study was conducted from December 2007 to May 2008. The age of the school children of the study was divided into two group: 5 - 6 years and 12 - 13 years. A stratifi ed cluster sampling with proportional allocation was used while grouping the subjects. The dental status examination was done with the help of trained dentists. Decayed, missed and fi lled teeth index and decayed, missed and fi lled surfaces index (dmft for primary dentition and DMFT for permanent dentition were used as the standard tools for the determination of prevalence. Results: A total of 638 students (325 of age group 12 - 13 years and 313 of age group 5 - 6 years from 30 different schools of the Kathmandu valley were included in the study. The caries status was found higher in the age group of 5 - 6 years than in the 12 - 13 years and it was found to be statistically signifi cant (p < 0.001. The dmfs and caries percentage of the age group 5 - 6 years and the DMFS and caries percent of the 12 - 13 years was found to be 3.79, 69 % and 1.6, 53.23 % respectively. The dmft/dmfs value was found to be signifi cant according to the districts in the 5 - 6 years age group whereas the DMFS was found statistically signifi cant among the sexes of the 12 - 13 years age group. Conclusions: The caries percentage was found to be above the recommended level of the World Health Organization. However, the DMFS and DMFT values were within the WHO level. Keywords: Children, dental caries, DMF index.

    Background and Aims Probiotics, prebiotics and synbiotics have been suggested as dietary strategies to improve intestinal barrier function. This study aimed to assess the effect of two weeks synbiotic supplementation on intestinal permeability under basal and stressed conditions. Secondary aims were the assessment of two weeks synbiotic supplementation on systemic immune function and gastrointestinal symptoms including defecation pattern. Design Twenty healthy adults completed a double-blind, controlled, randomized, parallel design study. Intervention Groups either received synbiotic (1.5 × 1010 CFU Ecologic® 825 + 10 g fructo-oligosaccharides (FOS P6) per day) or control supplements for two weeks. Outcomes Intestinal segment specific permeability was assessed non-invasively by oral administration of multiple sugar probes and, subsequently, assessing the excretion of these probes in urine. This test was conducted at baseline and at the end of intervention, in the absence and in the presence of an indomethacin challenge. Indomethacin was applied to induce a compromised gut state. Plasma zonulin, cytokines and chemokines were measured at baseline and at the end of intervention. Gastrointestinal symptoms and stool frequency were recorded at baseline and daily during intervention. Results Significantly more male subjects were in the synbiotic group compared to the control group (P = 0.025). Indomethacin significantly increased urinary lactulose/rhamnose ratio versus without indomethacin, both in the control group (P = 0.005) and in the synbiotic group (P = 0.017). Urinary sugar recoveries and ratios, plasma levels of zonulin, cytokines and chemokines, and gastrointestinal symptom scores were not significantly different after control or synbiotic intervention. Stool frequency within the synbiotic group was significantly increased during synbiotic intervention compared to baseline (P = 0.039) and higher compared to control intervention (P = 0.045). Conclusion Two weeks

    Full Text Available Background: Use of social networking services (SNS is on the rise. While many users sign in for personal purposes, it is not uncommon for professionals to connect over SNSs with clients, students, and patients. Methods: The present study used an experimental approach to examine how medical doctors’ SNS profiles impacted potential patients’ impressions of professionalism. Participants (N=250 students were randomly assigned to view one of six Facebook profiles. Profiles were populated with 1 solely professional material, 2 personal material that was strictly healthy, or 3 personal material that included unhealthy behavior. Profiles portrayed a male or female physician resulting in a total of six experimental conditions. Medical professionalism was measured with the First Impressions of Medical Professionalism (FIMP scale, specifically developed for this study. Results: There was a large and statistically significant main effect for profile type, F(2, 250=54.77, p<0.001, ηp2=0.31. Post hoc tests indicated that personal profiles that contained healthy behavior were rated as most professional followed by profiles with strictly professional content. Personal unhealthy profiles were rated as least professional. Additionally, female profiles consistently received higher professionalism ratings across all three profile types [F(1, 250=5.04, p=0.026, ηp2=0.02]. Conclusion: Our results suggest that a physician's SNS profile affects a patient's perception of that physician's medical professionalism. A personal, healthy profile may augment a patient's perception of that physician's character virtues if the profile content upholds the decorum of the medical field.

    Full Text Available Human connections are key to the promotion of health and prevention of illness; moreover, illness can cause deterioration of human connections. Healthcare professional–patient relationships are key to ensuring the preservation of adequate human connections. It is important for healthcare professionals to develop their ability to foster satisfactory human connections because: (i they represent social support for patients; and (ii they prevent work-related stress. In this study we assessed the relationship between absence (loneliness and presence (empathy of human connections with the occupational well-being of healthcare professionals. The Scale of Collateral Effects, which measures somatization, exhaustion, and work alienation; the Jefferson Scale of Empathy; and the Social and Emotional Loneliness Scale for Adults, were mailed to 628 healthcare professionals working in Spanish public healthcare institutions. The following explanatory variables were used to evaluate work well-being: (a empathy, as a professional competence; (b loneliness, age, and family burden, as psychological indicators; and (c professional experience, work dedication, and salary, as work indicators. Comparison, correlation, and regression analyses were performed to measure the relationships among these variables and occupational well-being. Of 628 surveys mailed, 433 (69% response rate were returned fully completed. Adequate reliability was confirmed for all instruments. The entire sample was divided into four groups, based on the combined variable, “occupation by sex.” Comparative analyses demonstrated differences among “occupation by sex” groups in collateral effects (p = 0.03 and empathy (p = 0.04, but not loneliness (p = 0.84. Inverse associations between empathy and collateral effects were confirmed for somatization (r = -0.16; p < 0.001, exhaustion (r = -0.14; p = 0.003, and work alienation (r = -0.16; p < 0.001. Furthermore, loneliness was positively

    Full Text Available The article highlights the urgent problem of contemporary art pedagogy – involvement to training future professional choreographic traditions of different nations. Addressing to this problem is caused by a number of socio-political events in Ukraine, mainstreaming of national and international education, integration of Ukrainian education with the European educational space, intensive development of domestic students’ intercultural communication with young people from different countries, which is the basis for updating national art education. Prospective choreographers, who are being training at pedagogical universities to manage children's dance groups, should actively be involved into creating their own productions of folk dance various genres. It promotes the formation of choreographers’ professional competence and pedagogical skills. The development of Georgian "Lezginka" is proposed – a joint creative work of the teacher and students who get higher education degree in SHEE “Donbass State Pedagogical University” (Bachelor's Degree. Development of the dance contains schematic drawings of dance figures, it is recommended for use in forming choreographers’ professional skills while studying the course "Folk Dance Theory and Methodology". The author admits that folklore material requires a cautious, respectful attitude. Therefore, modern folk stage dances are integrally to combine traditional choreographic manner with its new interpretations. The author believes the actual capture of different nations’ choreographic culture improves intercultural youth communication; involves future professionals into the traditions of different nations; form professional skills of managers of children’s dance groups. The author concluded that a dance always reflects consciousness of different nations; future choreographers should be aware of characteristic features of dances of different world nations so that on the basis of traditional

    Medical professionalism is a core competency for emergency medicine (EM) trainees; but defining professionalism remains challenging, leading to difficulties creating objectives and performing assessment. Because professionalism is dynamic, culture-specific, and often taught by modeling, an exploration of trainees' perceptions can highlight their educational baseline and elucidate the importance they place on general conventional professionalism domains. To this end, our objective was to assess the relative value EM residents place on traditional components of professionalism. We performed a cross-sectional, multi-institutional survey of incoming and graduating EM residents at four programs. The survey was developed using the American Board of Internal Medicine's "Project Professionalism" and the Accreditation Council of Graduate Medical Education definition of professionalism competency. We identified 27 attributes within seven domains: clinical excellence, humanism, accountability, altruism, duty and service, honor and integrity, and respect for others. Residents were asked to rate each attribute on a 10-point scale. We analyzed data to assess variance across attributes as well as differences between residents at different training levels or different institutions. Of the 114 residents eligible, 100 (88%) completed the survey. The relative value assigned to different professional attributes varied considerably, with those in the altruism domain valued significantly lower and those in the "respect for others" and "honor and integrity" valued significantly higher (p<0.001). Significant differences were found between interns and seniors for five attributes primarily in the "duty and service" domain (p<0.05). Among different residencies, significant differences were found with attributes within the "altruism" and "duty and service" domains (p<0.05). Residents perceive differences in the relative importance of traditionally defined professional attributes and this may

    Optical frequencies of the hyperfine components of the D 2 line in 133 Cs are determined using high-resolution spectroscopy and a femtosecond laser frequency comb. A narrow-linewidth probe laser excites the 6s 2 S 1/2 (F=3,4)→6p 2 P 3/2 (F=2,3,4,5) transition in a highly collimated atomic beam. Fluorescence spectra are taken by scanning the laser frequency over the excited-state hyperfine structure. The laser optical frequency is referenced to a Cs fountain clock via a reference laser and a femtosecond laser frequency comb. A retroreflected laser beam is used to estimate and minimize the Doppler shift due to misalignment between the probe laser and the atomic beam. We achieve an angular resolution on the order of 5x10 -6 rad. The final uncertainties (∼±5 kHz) in the frequencies of the optical transitions are a factor of 20 better than previous results [T. Udem et al., Phys. Rev. A 62, 031801 (2000).]. We find the centroid of the 6s 2 S 1/2 →6p 2 P 3/2 transition to be f D2 =351 725 718.4744(51) MHz

    This article describes the first successful crystallization of components of eukaryotic ribonucleases P/MRP. Yeast RNase MRP RNA domain P3 was crystallized in a complex with the proteins Pop6 and Pop7; the crystals diffracted to 3.25 Å resolution. Eukaryotic ribonucleases P and MRP are closely related RNA-based enzymes which contain a catalytic RNA component and several protein subunits. The roles of the protein subunits in the structure and function of eukaryotic ribonucleases P and MRP are not clear. Crystals of a complex that included a circularly permuted 46-nucleotide-long P3 domain of the RNA component of Saccharomyces cerevisiae ribonuclease MRP and selenomethionine derivatives of the shared ribonuclease P/MRP protein components Pop6 (18.2 kDa) and Pop7 (15.8 kDa) were obtained using the sitting-drop vapour-diffusion method. The crystals belonged to space group P4 2 22 (unit-cell parameters a = b = 127.2, c = 76.8 Å, α = β = γ = 90°) and diffracted to 3.25 Å resolution

    The aim of this study was to assess the incidence of micronuclei (MN) in buccal mucosal cells of professionals working in radiology area to determine the risk of stochastic effects of radiation. All the professionals and students working in King Khalid University - College of Dentistry radiology area were included in the Risk Group (RG = 27). The Control Group (CG = 27) comprised of healthy individual matching the gender and age of the RG. Buccal mucosal scraping from all the 54 subjects of RG and CG were stained with Papanicolaou stain and observed under oil immersion lens (×100) for the presence of micronuclei (MN) in the exfoliated epithelial cells. There was no significant difference between the incidence of MN in RG and CG (p = >0.05) using t-test. Routine radiation protection protocol does minimize the risk of radiation induced cytotoxicity, however, screening of professionals should be carried out at regular intervals.

    Site environmental characterization and remediation require data obtained from the installation and sampling of wells. When these wells are no longer needed or not producing reliable information, or are damaged and can act as conduits for contaminant migration, they should be identified and properly decommissioned. This is most important for wells of sufficient depth to create the potential for exchange of fluids between different hydrologic units. This plan presents the strategy and detailed approach for well plugging and abandonment (P ampersand A) at Waste Area Grouping 6 (WAG 6). An inventory of 768 wells, the total number known to have been installed in WAG 6 based on a combined review of data and direct field inventory, is provided in Appendix A. All wells that are no required for closure or postclosure surveillance of WAG 6 will be decommissioned. A listing of 69 existing WAG 6 wells that will be maintained for postclosure surveillance is provided in Appendix B, and their locations are shown in Fig. 1. Appendix C contains a list of all WAG 6 wells that will be decommissioned, although some may no longer exist. Their locations are shown in Fig. 2. It is likely that some new wells will be drilled as part of postclosure monitoring of Solid Waste Area 6 (SWSA), but they are beyond the scope of this report. It is intended that this plan provide a basis for developing contracts for cost and schedule determinations for the P ampersand A process

    We examined gender differential changes in employment-related health inequalities according to occupational position (professional/nonprofessional) in South Korea during the last decade. Data were taken from four rounds of Social Statistical Surveys of South Korea (1995, 1999, 2003, and 2006) from the Korean National Statistics Office. The total study population was 55435 male and 33 913 female employees aged 25-64. Employment arrangements were divided into permanent, fixed-term, and daily employment. After stratification according to occupational position (professional/nonprofessional) and gender, different patterns in employment - related health inequalities were observed. In the professional group, the gaps in absolute and relative employment inequalities for poor self-rated health were more likely to widen following Korea's 1997 economic downturn. In the nonprofessional group, during the study period, graded patterns of employment-related health inequalities were continuously observed in both genders. Absolute health inequalities by employment status, however, decreased among men but increased among women. In addition, a remarkable increase in relative health inequalities was found among female temporary and daily employees (p = 0.009, women. In view of the high concentration of female nonstandard employees, further monitoring of inequality should consider gender specific patterns according to employee's occupational and employment status.

    Full Text Available Background: The Development of Groups and Leaders (UGL, provided by the Swedish National Defence College and mentored by UGL-trainers, is one of the most popular management programs among civilians in Sweden. However, there is a lack of scientific evidence regarding the training. We used the affective profile model (i.e., the combination of positive, PA, and negative affect, NA to mapp important markers of empowerment, self-awareness, adaptive coping skills, and maturity among the UGL-trainers. The aims were: (1 to compare profiles between UGL-trainers and managers/supervisors and (2 to investigate differences in personal characteristics.Method: UGL-trainers (N = 153 and the comparison group (104 Swedish Chiefs of Police completed an online survey on optimism, self-esteem, locus of control, and affect. The four profiles are: self-fulfilling (high PA, low NA, high affective (high PA, high NA, low affective (high PA, low NA, and self-destructive (low PA, high NA,Results: The self-fulfilling profile was more common among UGL-trainers (25.70% than among Chiefs of Police (19.20%. UGL-trainers, compared to Chiefs of Police, were more likely to express a self-fulling than a low affective profile (OR=2.22, p < .05 and a high affective than a low affective profile (OR=1.43, p <.001. UGL-trainers with a self-fulfilling profile, compared to those with a self-destructive profile, scored higher in optimism, higher in self-esteem, and lower in external locus of control. Conclusions: The probability of self-fulfilment rather than low affectivity was higher among UGL-trainers. Self-fulfilment was associated to markers of self-awareness and adaptive coping skills. However, the most common profile was the low affective, which is associated to low performance during stress, low degree of personal development, low degree of purpose in life, and low resilience. Hence, it might be important for UGL-trainers to have a continuos training in awareness after

    As newcomers to the clinical workplace, nursing students will encounter a high degree of role stress, which is an important predictor of burnout and engagement. Professional identity is theorised to be a key factor in providing high-quality care to improve patient outcomes and is thought to mediate the negative effects of a high-stress workplace and improve clinical performance and job retention. To investigate the level of nursing students' professional identity and role stress at the end of the first sub-internship, and to explore the impact of the nursing students' professional identity and other characteristics on role stress. A cross-sectional study. Three nursing schools in China. Nursing students after a 6-month sub-internship in a general hospital (n=474). The Role Stress Scale (score range: 12-60) and the Professional Identity Questionnaire for Nursing students (score range: 17-85) were used to investigate the levels of nursing students' role stress and professional identity. Higher scores indicated higher levels of role stress and professional identity. Basic demographic information about the nursing students was collected. The Pearson correlation, point-biserial correlation and multiple linear regression analysis were used to analyse the data. The mean total scores of the Role Stress Scale and Professional Identity Questionnaire for Nursing Students were 34.04 (SD=6.57) and 57.63 (SD=9.63), respectively. In the bivariate analyses, the following independent variables were found to be significantly associated with the total score of the Role Stress Scale: the total score of the Professional Identity Questionnaire for Nursing Students (r=-0.295, pNursing Students (standardised coefficient Beta: -0.260, pStress Scale.

    The simplest atoms having nonspherical symmetry are those with a single p electron in a valence shell. Of these, the group IIIB elements are excellent examples. As such, they form test cases for photoionization from open-shell systems. Through photoelectron-spectroscopy techniques, we have examined both partial cross sections and angular-distribution parameters for autoionization corresponding to promotion of a 3d electron to the 4p shell of gallium. The resulting dp 2 configuration gives rise to a complicated multiplet structure across which the angular-distribution parameter varies considerably. We have also looked at the simpler structure resulting from promotion of one s electron to an np level, n = 5,6. For these cases, the multiplet structure is simpler, but the influence of the resonance on the cross section and the angular distribution is pronounced. For the 4s4p( 3 P)5p resonance we find a value of β = -1 at the cross-section minimum. No calculations have been performed for this system, so we attempt a qualitative interpretation of our results based on an angular-momentum-transfer analysis

    The purpose of this study was to measure professional and personal values among nurses, and to identify the factors affecting these values. The participants were 323 Israeli nurses, who were asked about 36 personal values and 20 professional values. The three fundamental professional nursing values of human dignity, equality among patients, and prevention of suffering, were rated first. The top 10 rated values all concerned nurses' responsibility towards patients. Altruism and confidentiality were not highly rated, and health promotion and nursing research were rated among the last three professional values. For personal (instrumental) values, honesty, responsibility and intelligence were rated first, while ambition and imagination were rated 14th and 16th respectively out of 18. Significant differences (P personal and professional values rated as functions of culture, education, professional seniority, position and field of expertise. The results may assist in understanding the motives of nurses with different characteristics and help to promote their work according to professional ethical values.

    Bi 6.4 Pb 0.6 P 2 O 15.2 is a polymorph of structures with the general stoichiometry Bi 6+x M 1-x P 2 O 15+y . However, unlike previously published structures that consist of layers formed by edge sharing OBi 4 tetrahedra bridged by PO 4 and TO 6 (T=transition metal) tetrahedra and octahedra the title compound's structure is more complex. It is monoclinic, C2, a=19.4698(4) A, b=11.3692(3) A, c=16.3809(5) A, β=101.167(1) o , Z=10. Single-crystal X-ray diffraction data were refined by least squares on F 2 converging to R 1 =0.0387, wR 2 =0.0836 for 7023 intensities. The crystal twins by mirror reflection across (001) as the twin plane and twin component 1 equals 0.74(1). Oxygen ions are in tetrahedral coordination to four metal ions and the O(BiPb) 4 units share corners to form layers that are part of the three-dimensional framework. Eight oxygen ions form a cube around the two crystallographically independent Pb ions. Pb-O bond lengths vary from 2.265(14) to 2.869(14) A. Pairs of such cubes share an edge to form a Pb 3 O 20 unit. The two oxygen ions from the unshared edges are part of irregular Bi polyhedra. Other oxygen ions of Bi polyhedra are part only of O(BiPb) 4 units, and some oxygen ions of the polyhedra are also part of PO 4 tetrahedra. One, two, three and or four PO 4 moieties are connected to the Bi polyhedra. Bi-O bond lengths ≤3.1 A vary from 2.090(12) to 3.07(3) A. The articulations of Pb cubes, Bi polyhedra and PO 4 tetrahedra link into the three-dimensional structure. - Graphical abstract: View of the structure of Bi 6.4 Pb 0.6 P 2 O 15.2 parallel to the b-axis

    The aesthetic outcome of cleft treatment is of great importance due to its complex management and the psychosocial consequences of this defect. The aim of the study was to assess the aesthetic evaluations of patients following cleft surgery by various groups and investigate potential associations of the assessments with life quality parameters. Head photos of 12 adult patients with treated unilateral cleft lip and palate were evaluated by laypeople and professionals. A questionnaire was distributed and answered by the patients and their parents. Intra-panel agreement was high (α > 0.8) for laypeople and professionals. Between-groups agreement was high for both laypeople and professionals, but not when patients and/or parents were tested. Professionals, parents, and patients were more satisfied with patients' appearance than laypeople, although in general all groups were not highly satisfied. Low satisfaction with aesthetics correlated with increased self-reported influence of the cleft in the patients' social activity and professional life (0.56 < rho < 0.74, p < 0.05). These findings highlight the observed negative influence of the cleft on the patient's social activity and professional life and underline the need for the highest quality of surgical outcome for this group of patients.

    Full Text Available This descriptive study was designed to analyze the level of group cohesion and pre-competitive psychological stress of adult volleyball athletes. The subjects consisted of 155 male and female athletes from the state of Parana who played in the JAPS/ 1st division (A, and 2nd division (B. The assessment instruments used were the Group Environment Questionnaire (GEQ and the Volleyball Psychic Stress Test (V-PST. For data analysis, the following tools were used: Cronbach’s alpha, Kolmogorov-Smirnov, Mann-Whitney, one-way Anova, and Tukey’s post hoc (p<0.05. The results revealed that athletes of division A were more negatively influenced by stress factors than the athletes of division B; in terms of individual attraction to the social group (p=0.014 and tasks (p=0016 athletes of division B had higher levels of group cohesion than athletes from division A; athletes with low social cohesion were negatively impacted by factors of "inappropriate physical conditioning" and "excessive nervousness;" athletes with low levels of cohesion for the task were negatively influenced by the factors of "Pressure from other people to win" and positively by the factor "Behavior of the fans in the game outside." It was concluded that group cohesion is demonstrated to be an intervening factor in pre-competitive stress thereby demonstrating that the higher the dispute level, the higher the negative influence of stress.

    The main objective of the project was to use the methodology developed in the previous Methodology project (ETSU/FES Project K/EL/00287) to assess the security capability of modern distributed generation in order to review Table 2 and related text of Engineering Recommendation P2/5, and to propose information and results that could be used to create a new P2/6 that takes into account modern types of generating units; unit numbers; unit availabilities; and capacities. Technical issues raised in the previous study but held over until this project include: Treatment of single unit generation systems; Effect of shape of load duration curves; Persistence of intermittent generation, T{sub m}; Time resolution of intermittent generation output profiles; Ride-through capability; Risk to loss of supply. Three main ways of implementing the methodology were recommended: Look-up table(s), Graphical, and Computer program. The specification for the computer program was to produce a simple spreadsheet application package that an engineer with a reasonably knowledge of the approach could use. This prototype package has been developed in conjunction with Workstream 3. Its objective is to calculate the capability contribution to security of supply from distributed generation connected to a particular demand group. The application has been developed using Microsoft Excel and Visual Basic for Applications. New Tables for inclusion in P2/6 are included. (UK)

    This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals' performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study's inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p=.001), who were more familiar with consultation (p=.002), who had more positive attitudes and beliefs about consultation (p=.011) and who reported being more susceptible to the behavior (p=.001) and expectations/opinions (p=.025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals' responses to CAN are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This study was carried out in order to determine professional self-concept and professional values in the students, who were studying in the final year of the nursing department in schools providing undergraduate education in the Inner Anatolia Region. This cross-sectional study was conducted on a total of 619 senior students of nursing departments in the Inner Anatolia Region. Data were collected using a Student Information Form, Professional Self-Concept Scale for the Student Nurses, and The Nurses' Professional Values Scale. Descriptive statistics, the Shapiro-Wilk test, the t-test, analysis of variance, and the Bonferroni tests were used for data analysis. Ethical Considerations: A written consent was obtained from Ethics Board of Erciyes University Faculty of Medicine and from nursing schools participating in the study. Prior to data collection, students were informed about the purpose of the study and gave written and verbal consents. Participation in the study was on voluntary basis. In the study, students' total and sub-dimension scores from the Professional Self-Concept Scale for the Student Nurses and total scores from the Nurses' Professional Values Scale were moderately high. It was detected that women received higher scores than men from the sub-dimension of professional attributes; the students who had positive perception of the nursing image and voluntarily selected their department received high scores from professional satisfaction, professional competence, and professional attributes sub-dimensions of the Professional Self-Concept Scale for the Student Nurses ( p concept and professional values, it is thought that students' awareness should be increased on these topics.

    D-6-Deoxy-myo-inositol 1,3,4,5-tetrakisphosphate [D-6-deoxy-Ins(1,3,4,5)P 4 ] 3 is a novel deoxygenated analogue of D-myo-inositol 1,3,4,5-tetrakisphosphate [Ins(1,3,4,5)P 4 ] 2, a central and enigmatic molecule in the polyphosphoinositide pathway of cellular signalling. D-6-Deoxy-Ins(1,3,4,5)P 4 is a moderate inhibitor of Ins(1,4,5)P 3 5-phosphatase [1.8 μM] compared to Ins(1,3,4,5)P 4 [0.15 μM] and similar to that of L-Ins(1,3,4,5)P 4 [1.8 μM]. In displacement of [ 3 H] Ins(1,4,5)P 3 from the rat cerebellar Ins(1,4,5)P 3 receptor, while slightly weaker [IC 50 =800 nM] than that of D-Ins(1,3,4,5)P 4 [IC 50 =220 nM], 3 is less markedly different and again similar to that of L-Ins(1,3,4,5)P 4 [IC 50 =660 nM]. 3 is an activator of I CRAC when inward currents are measured in RBL-2H3-M1 cells using patch-clamp electrophysiological techniques with a facilitation curve different to that of Ins(1,3,4,5)P 4 . Physicochemical properties were studied by potentiometric 31 P and 1 H NMR titrations and were similar to those of Ins(1,3,4,5)P 4 apart from the observation of a biphasic titration curve for the P1 phosphate group. A novel vicinal phosphate charge-induced conformational change of the inositol ring above pH 10 was observed for D-6-deoxy-Ins(1,3,4,5)P 4 that would normally be hindered because of the central stabilising role played by the 6-OH group in Ins(1,3,4,5)P 4 . We conclude that the 6-OH group in Ins(1,3,4,5)P 4 is crucial for its physicochemical behaviour and biological properties of this key inositol phosphate

    Full Text Available Introduction: Medical professionalism is a core competency for emergency medicine (EM trainees; but defining professionalism remains challenging, leading to difficulties creating objectives and performing assessment. Because professionalism is dynamic, culture-specific, and often taught by modeling, an exploration of trainees’ perceptions can highlight their educational baseline and elucidate the importance they place on general conventional professionalism domains. To this end, our objective was to assess the relative value EM residents place on traditional components of professionalism. Methods: We performed a cross-sectional, multi-institutional survey of incoming and graduating EM residents at four programs. The survey was developed using the American Board of Internal Medicine’s “Project Professionalism” and the Accreditation Council of Graduate Medical Education definition of professionalism competency. We identified 27 attributes within seven domains: clinical excellence, humanism, accountability, altruism, duty and service, honor and integrity, and respect for others. Residents were asked to rate each attribute on a 10-point scale. We analyzed data to assess variance across attributes as well as differences between residents at different training levels or different institutions. Results: Of the 114 residents eligible, 100 (88% completed the survey. The relative value assigned to different professional attributes varied considerably, with those in the altruism domain valued significantly lower and those in the “respect for others” and “honor and integrity” valued significantly higher (p<0.001. Significant differences were found between interns and seniors for five attributes primarily in the “duty and service” domain (p<0.05. Among different residencies, significant differences were found with attributes within the “altruism” and “duty and service” domains (p<0.05. Conclusion: Residents perceive differences in

    Healthcare professionals are expected to have knowledge of current basic and advanced cardiac life support (BLS/ACLS) guidelines to revive unresponsive patients. A cross-sectional study was conducted to evaluate the current practices and knowledge of BLS/ACLS principles among healthcare professionals of North-Kerala using pretested self-administered structured questionnaire. Answers were validated in accordance with American Heart Association's BLS/ACLS teaching manual and the results were analysed. Among 461 healthcare professionals, 141 (30.6%) were practicing physicians, 268 (58.1%) were nurses and 52 (11.3%) supporting staff. The maximum achievable score was 20 (BLS 15/ACLS 5). The mean score amongst all healthcare professionals was 8.9±4.7. The mean score among physicians, nurses and support staff were 8.6±3.4, 9±3.6 and 9±3.3 respectively. The majority of healthcare professionals scored ≤50% (237, 51.4%); 204 (44.3%) scored 51%-80% and 20 (4.34%) scored >80%. Mean scores decreased with age, male sex and across occupation. Nurses who underwent BLS/ACLS training previously had significantly higher mean scores (10.2±3.4) than untrained (8.2±3.6, P =0.001). Physicians with <5 years experience ( P =0.002) and nurses in the private sector ( P =0.003) had significantly higher scores. One hundred and sixty three (35.3%) healthcare professionals knew the correct airway opening manoeuvres like head tilt, chin lift and jaw thrust. Only 54 (11.7%) respondents were aware that atropine is not used in ACLS for cardiac arrest resuscitation and 79 (17.1%) correctly opted ventricular fibrillation and pulseless ventricular tachycardia as shockable rhythms. The majority of healthcare professionals (356, 77.2%) suggested that BLS/ACLS be included in academic curriculum. Inadequate knowledge of BLS/ACLS principles amongst healthcare professionals, especially physicians, illuminate lacunae in existing training systems and merit urgent redressal.

  18. Rice black-streaked dwarf virus P6 self-interacts to form punctate, viroplasm-like structures in the cytoplasm and recruits viroplasm-associated protein P9-1

    Full Text Available Abstract Background Rice black-streaked dwarf virus (RBSDV, a member of the genus Fijivirus within the family Reoviridae, can infect several graminaceous plant species including rice, maize and wheat, and is transmitted by planthoppers. Although several RBSDV proteins have been studied in detail, functions of the nonstructural protein P6 are still largely unknown. Results In the current study, we employed yeast two-hybrid assays, bimolecular fluorescence complementation and subcellular localization experiments to show that P6 can self-interact to form punctate, cytoplasmic viroplasm-like structures (VLS when expressed alone in plant cells. The region from residues 395 to 659 is necessary for P6 self-interaction, whereas two polypeptides (residues 580-620 and 615-655 are involved in the subcellular localization of P6. Furthermore, P6 strongly interacts with the viroplasm-associated protein P9-1 and recruits P9-1 to localize in VLS. The P6 395-659 region is also important for the P6-P9-1 interaction, and deleting any region of P9-1 abolishes this heterologous interaction. Conclusions RBSDV P6 protein has an intrinsic ability to self-interact and forms VLS without other RBSDV proteins or RNAs. P6 recruits P9-1 to VLS by direct protein-protein interaction. This is the first report on the functionality of RBSDV P6 protein. P6 may be involved in the process of viroplasm nucleation and virus morphogenesis.

    Pop6 and Pop7 are protein subunits of Saccharomyces cerevisiae RNase MRP and RNase P. Here we show that bacterially expressed Pop6 and Pop7 form a soluble heterodimer that binds the RNA components of both RNase MRP and RNase P. Footprint analysis of the interaction between the Pop6/7 heterodimer and the RNase MRP RNA, combined with gel mobility assays, demonstrates that the Pop6/7 complex binds to a conserved region of the P3 domain. Binding of these proteins to the MRP RNA leads to local rearrangement in the structure of the P3 loop and suggests that direct interaction of the Pop6/7 complex with the P3 domain of the RNA components of RNases MRP and P may mediate binding of other protein components. These results suggest a role for a key element in the RNase MRP and RNase P RNAs in protein binding, and demonstrate the feasibility of directly studying RNA-protein interactions in the eukaryotic RNases MRP and P complexes.

    This study assessed differences in program satisfaction among health professionals participating in a distance continuing education program by gender, ethnicity, discipline, and community size. A one-group posttest design was used with a sample of 45,996 participants in the University of Arkansas for Medical Sciences, Rural Hospital, Distance Continuing Medical Education Program during 1995-2007. This program provided 2,219 continuing education programs for physicians (n = 7,047), nurses (n = 21,264), allied health (n = 3,230) and dental (n = 305) professionals, pharmacists (n = 4,088), administrators (n = 1,211), and marketing/finance/human resources professionals (n = 343). These programs were provided in Arkansas hospitals, clinics, and area health education centers. Interactive video technology and the Internet were used to deliver these programs. The program satisfaction instrument demonstrated adequate internal consistency reliability (Cronbach's alpha = 0.91) and construct validity. Participants had high levels of satisfaction regarding knowledge and skills, use of information to enhance patient care, program quality, and convenience of the technology (mean total satisfaction score = 4.44, range: 1-5). Results from the t-test for independent samples and one-way analysis of variance indicated that men (p = 0.01), African-Americans and Hispanics (p affect satisfaction with distance continuing education programs.

    Adenosine diphosphate (ADP) is a critical regulator of platelet activation, mediating its actions through two G protein-coupled receptors, the P2Y(1) and P2Y(12) purinoceptors. Recently, we demonstrated that P2Y(1) and P2Y(12) purinoceptor activities are rapidly and reversibly modulated in human platelets, revealing that the underlying mechanism requires receptor internalization and subsequent trafficking as an essential part of this process. In this study we investigated the role of the small GTP-binding protein ADP ribosylation factor 6 (ARF6) in the internalization and function of P2Y(1) and P2Y(12) purinoceptors in human platelets. ARF6 has been implicated in the internalization of a number of GPCRs, although its precise molecular mechanism in this process remains unclear. In this study we show that activation of either P2Y(1) or P2Y(12) purinoceptors can stimulate ARF6 activity. Further blockade of ARF6 function either in cell lines or human platelets blocks P2Y purinoceptor internalization. This blockade of receptor internalization attenuates receptor resensitization. Furthermore, we demonstrate that Nm23-H1, a nucleoside diphosphate (NDP) kinase regulated by ARF6 which facilitates dynamin-dependent fission of coated vesicles during endocytosis, is also required for P2Y purinoceptor internalization. These data describe a novel function of ARF6 in the internalization of P2Y purinoceptors and demonstrate the integral importance of this small GTPase upon platelet ADP receptor function.

    Let G be a finite p-group generated by (g i , 1 ≤ i ≤ d), G i the cyclic subgroup generated by g i , E the free product of the G i , 1 ≤ i ≤ d, and S the kernel of the natural epimorphism of E onto G. The largest elementary abelian p-quotient S-circumflex = S/S'S p , regarded as an IF p G-module via conjugation in E, is called a relative relation module of G. If d is the minimum number of generaters for G, the author has proved that S-circumflex is nonprojective and indecomposable. The aim of this paper is to give an alternative proof for the indecomposability of S-circumflex; the proof here is more informative as it deals with Loewy structure and generating sets of S-circumflex and other associated modules.

    The Xe 4d -1 6p→5s 0 5p 6 6p and 5s 1 5p 5 6p resonant Auger transitions have been studied both theoretically and experimentally. High resolution resonant Auger spectra have been recoded with different photon bandwidths which have enabled to separate the first step Auger transition from the overlapping second step transitions. Theoretical calculations using multi-configuration Dirac-Fock approach with different configuration expansions were carried out, compared to each other and to the experiment. The calculations with the largest basis set were found to reproduce the distribution of the intensity to the main and satellite lines in both the 5s 0 5p 6 6p and 5s 1 5p 5 6p Auger groups reasonably well, and to predict the structure of the 4d -1 6p→5s 0 5p 6 6p main lines very well

    The objective of this study is to estimate the seroprevalence of human brucellosis in livestock professionals and analyze the factors associated with brucellosis focusing on sociodemographic variables and the variables of knowledge and practices related to the characteristics of the activities carried out in livestock. This is a cross-sectional seroepidemiological study with a population of 131 workers of butchers, slaughter rooms, and slaughterhouse and 192 breeders sampled randomly in Namibe province, Angola. The data were obtained from the collection of blood and use of questionnaires. The laboratory tests used were rose bengal and slow agglutination. The questionnaire allowed us to collect sociodemographic information and, specifically on brucellosis, it incorporated questions about knowledge, attitudes, and behaviors of livestock professionals. In addition to the descriptive statistical approach, we used the Chi-square test of independence, Fisher's test, and logistic regression models, using a significance level of 10%. The general weighted prevalence of brucellosis was 15.6% (95%CI 13.61-17.50), being it 5.3% in workers and 16.7% (95%CI 11.39-21.93) in breeders. The statistical significance was observed between human seroprevalence and category (worker and breeder) (p brucellosis in professionals was the professional category (OR = 3.54; 95%CI 1.57-8.30, related to breeders in relation to workers). Human brucellosis in livestock professionals is prevalent in Namibe province (15.6%), where the professional category was the most important factor. The seroprevalence levels detected are high when compared with those found in similar studies.

    Full Text Available BACKGROUND: Life and death decisions of metazoan cells hinge on the balance between the expression of pro- versus anti-apoptotic gene products. The general RNA polymerase II transcription factor, TFIID, plays a central role in the regulation of gene expression through its core promoter recognition and co-activator functions. The core TFIID subunit TAF6 acts in vitro as an essential co-activator of transcription for the p53 tumor suppressor protein. We previously identified a splice variant of TAF6, termed TAF6delta that can be induced during apoptosis. METHODOLOGY/PRINCIPAL FINDINGS: To elucidate the impact of TAF6delta on cell death and gene expression, we have employed modified antisense oligonucleotides to enforce expression of endogenous TAF6delta. The induction of endogenous TAF6delta triggered apoptosis in tumor cell lines, including cells devoid of p53. Microarray experiments revealed that TAF6delta activates gene expression independently of cellular p53 status. CONCLUSIONS: Our data define TAF6delta as a pivotal node in a signaling pathway that controls gene expression programs and apoptosis in the absence of p53.

    An advanced undergraduate experiment to study the 5 P 3 / 2 → 6 P 3 / 2 electric quadrupole transition in rubidium atoms is presented. The experiment uses two external cavity diode lasers, one operating at the D2 rubidium resonance line and the other built with commercial parts to emit at 911 nm. The lasers produce the 5 s → 5 p6 p excitation sequence in which the second step is the forbidden transition. Production of atoms in the 6 P 3 / 2 state is observed by detection of the 420 nm fluorescence that results from electric dipole decay into the ground state. Lines whose widths are significantly narrower than the Doppler width are used to study the hyperfine structure of the 6 P 3 / 2 state in rubidium. The spectra illustrate characteristics unique to electric dipole forbidden transitions, like the electric quadrupole selection rules; they are also used to show general aspects of two-color laser spectroscopy such as velocity selection and hyperfine pumping.

    The prevalence of allergy, lung function disorders, and bronchial hyperreactivity was studied in 102 Dutch veterinarians, subdivided into five professional groups (predominantly working with either swine, cattle, poultry, companion animals, or as a non-practitioner). The mean age of the participants was 43 years; 6 participants were females. Twenty-two per cent of the participants were overweight, and relatively more non-practitioners than practitioners were overweight. Approximately 23% of the vets reported complaints of prolonged fatigue. The data suggest a relationship between complaints of prolonged fatigue and a more than average number of daily working hours. Only a small proportion of vets were sensitized against several allergens. There were no significant differences in prevalence of distinct lung function disorders or bronchial hyperreactivity between professional groups. It is hypothesized that the respiratory complaints (chronic coughing, chronic phlegm production, stuffed nose, sneezing) reported by the vets predominantly working in swine and/or poultry practice could be caused by irritation and/or inflammation of the first part of the trachea-bronchial tree that has no measurable and permanent consequences for changes in lung function or increased bronchial hyperreactivity. The results of a skin test against allergens and determination of allergen-specific IgE in blood indicated that the respiratory complaints were probably not related to allergy against the panel of allergens tested.

    The inclusion interaction between propranolol (PPL) and p-sulfonatocalix[6]arene (SCX6) was investigated by fluorescence and 1H NMR spectroscopy. Influences of pH, temperature, ionic strength and the concentration of SCX6 were examined in detail. In phosphate buffer solution with pH 7.5, the fluorescence of PPL dramatically quenched upon addition of SCX6 revealing the formation of inclusion complexes between PPL and SCX6. The stoichiometric ratio was verified to be 1:1 by the continuous variation method. The inclusion constant of PPL-SCX6 complexes was calculated as 2.2 × 104 L/mol by the nonlinear curve fitting method. 1H NMR titration spectra testified that the aliphatic chain of PPL may be partially penetrated into the hydrophobic cavity of SCX6. This was confirmed by molecular dynamics calculations.

    The purpose of this study was to examine the effectiveness of maximal and rapid isometric torque characteristics of the posterior muscles of the hip and thigh and lower-body power to discriminate between professional status in full-time and part-time professional soccer referees. Seven full-time (mean ± SE: age = 36 ± 2 years; mass = 82 ± 4 kg; and height = 179 ± 3 cm) and 9 part-time (age = 34 ± 2 years; mass = 84 ± 2 kg; and height = 181 ± 2 cm) professional soccer referees performed 2 isometric maximal voluntary contractions (MVCs) of the posterior muscles of the hip and thigh. Peak torque (PT) and absolute and relative rate of torque development (RTD) were calculated from a torque-time curve that was recorded during each MVC. Lower-body power output was assessed through a vertical jump test. Results indicated that the rapid torque characteristics were greater in the full-time compared with the part-time referees for absolute RTD (p = 0.011) and relative RTD at 1/2 (p = 0.022) and 2/3 (p = 0.033) of the normalized torque-time curve. However, no differences were observed for PT (p = 0.660) or peak power (Pmax, p = 0.149) between groups. These findings suggest that rapid torque characteristics of the posterior muscles of the hip and thigh may be sensitive and effective measures for discriminating between full-time and part-time professional soccer referees. Strength and conditioning coaches may use these findings to help identify professional soccer referees with high explosive strength-related capacities and possibly overall refereeing ability.

    muscle injury detection. The use of 0.47 of Hcon/Qcon as a discriminate value resulted in significantly lower sensitivity when compared to 0.658 threshold (sensitivity of 16.7% vs. 91.7%, respectively; t = 6.125,p = 0.0133. Calculated values of specificity (when three different cut-off were applied were also significantly different. Threshold of 0.6 of Hcon/Qcon resulted with significantly lower specificity compared to 0.47 value (specificity of 46.9% vs. 94.5%, respectively; t = 153.0,p<0.0001, and significantly higher specificity when compared to 0.658 (specificity of 46.9% vs. 24.1%, respectively; t = 229.0, p<0.0001.The use of different cut-off values for Hcon/Qcon significantly affected the sensitivity and specificity of isokinetic testing. The interpretation of usefulness of isokinetic test as a screening tool in a group of male professional football players to predict hamstring injury occurrence within the next 12 months might be therefore significantly biased due to the different threshold values of Hcon/Qcon. Using one "normative" value as a cut-off (e.g. 0.47 or 0.60, or 0.658 to quantify soccer players (or not to the group with a higher risk of knee injury might result in biased outcomes due to the natural strength asymmetry that is observed within the group of soccer players.

    Herein we report the results of detailed crystallographic studies of Ca 1-x Ba x Zr 4 P 6 O 24 compositions from combined Rietveld refinements of powder X-ray and neutron diffraction data. All the studied compositions crystallize in rhombohedral lattice (space group R-3 No. 148). A continuous solid solution is concluded from the systematic variation of unit cell parameters. The variation of unit cell parameters with the composition indicates decreasing trend in α parameter with increasing Ba 2+ concentration contrast to an increasing trend in c parameter. (author)

    2012-02-01

    SUMMARY: Professional jockeys are routinely exposed to high impact trauma and sustain fractures frequently. We found that jockeys restrict their caloric intake in order to maintain regulation weights, and that bone turnover is high. There are significant health and safety implications for the racing industry. INTRODUCTION: Professional jockeys routinely sustain fractures from high impact falls. Jockeys maintain a low percentage body fat and a low body mass index (BMI) to achieve low weight targets in order to race. We evaluated dietary habits and bone metabolism in jockeys. METHODS: Bone mineral density (BMD) was measured in 27 male jockeys of the 144 jockeys licensed in Ireland. Fourteen (52%) had BMD T score below -1.0, of whom 12 consented to clinical review, nutritional survey, endocrine studies, and bone turnover markers (BTM). BTM were compared to age- and sex-matched controls (n = 16). RESULTS: BMI was 20.6 +\\/- 1.7 kg\\/m(2); previous fracture frequency was 3.2 +\\/- 2.0 per rider. All had normal endocrine axes. The jockeys\\' diet as determined by a 7-day dietary recall was deficient in energy, calcium, and vitamin D intake. Compared with the control group, the jockey group had evidence of increased bone turnover. CONCLUSIONS: A substantial proportion of the professional jockeys in Ireland have low-normal BMD, low BMI, and high bone turnover that may result from weight and dietary restrictions. These factors seem to have a deleterious effect on their bone health and predispose the jockeys to a high fracture risk that should be remediated.

    Previous studies indicated that constitutive over-expression of cytochrome P450 CYP6B7 was involved in fenvalerate resistance in Helicoverpa armigera. In this study, the CYP6B7 gene from H. armigera (namely HaCYP6B7), was heterologously expressed in Pichia pastoris GS115. A vector pPICZA-HaCYP6B7 was constructed and transformed into P. pastoris GS115, the transformant of pPICZA-HaCYP6B7-GS115 was then cultured and induced by 1% (v/v) methanol and the heterologous expression of HaCYP6B7 protein in P. pastoris was confirmed by SDS-PAGE and western blot. Microsomes containing the expressed HaCYP6B7 showed activities against model substrate p-nitroanisole and 7-ethoxycoumarin, with p-nitroanisole O-demethylation (PNOD) and 7-ethoxycoumarin O-deethylation (ECOD) activities of 15.66- and 4.75-fold of the control, respectively. Moreover, it showed degradation activities against the insecticides bifenthrin, fenvalerate and chlorpyrifos, with clearance activities of 6.88-, 1.49- and 2.27-fold of the control, respectively. The interactions of HaCYP6B7 with insecticides were further confirmed by molecular docking in silico with binding scores of 5.450, 5.295 and 2.197 between putative HaCYP6B7 protein and bifenthrin, fenvalerate and chlorpyrifos, respectively. The results of present study provided more direct and important evidence on the role of HaCYP6B7 conferring pyrethroid resistance in H. armigera. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available Background: Grip and pinch strength are commonly employed indices of strength used in hand evaluations. Pinch grip and power grip strengths are used as indices of strength in hand therapy assessments. For all professions grip strength is an important criterion to be successful in their profession. Such phenomena may be explained by differences in nature of work, working environment, and objects workers handle. Method: 200 healthy subjects, satisfying the selection criteria were included and assessed with standardized procedure for power grip and pinch grip (lateral pinch, pad-pad, and tip-tip strength. They were divided in four groups, 50 group each according to profession i.e. medical surgeons, dentist, physiotherapists and nurses. Results: The mean power grip strength shows highly significant difference between medical vs. dental (p>0.01 and medical vs. physiotherapy group (p> 0.05 .The mean lateral pinch strength shows there is highly significant difference (p< 0.001 between dental vs. nursing profession and dental vs. physiotherapy group. No significant difference among other groups. The mean pad-pad pinch strength shows there is significant difference between dental vs. nursing (p< 0.05 and dental vs physiotherapy group (p< 0.05. The mean Tip-Tip pinch strength shows there is significant difference between dental vs nursing profession(p< 0.05 and dental vs. physiotherapy(p< 0.05. No significant different among other groups. Conclusion: Surgeons have highest power grip strength followed by Nursing, Physiotherapy and Dental professionals. Dentists have the maximum pinch strength in all three positions, followed by Surgeons, Nurses and Physiotherapists. Surgeons have maximum pinch strength next to Dentists.

    Ballet is a high-performance activity that requires an advanced level of technical skills. Ballet places great stress on tendons, muscles, bones, and joints and may act directly as a trigger of injury by overuse. 1) to describe the main types of injuries and affected areas related to classical ballet and 2) to compare the frequency of musculoskeletal injuries among professional and non-professional ballet dancers, considering possible gender differences among the professional dancers. A total of 110 questionnaires were answered by professional and non-professional dancers. The questionnaire contained items related to the presence of injury, the regions involved, and the mechanism of the injury. We observed a high frequency of musculoskeletal injuries, with ankle sprains accounting for 69.8% of injuries in professional dancers and 42.1% in non-professional dancers. Pirouettes were the most frequent mechanism of injury in professional dancers, accounting for 67.9% of injuries, whereas in the non-professional dancers, repetitive movement was the most common mechanism (28.1%). Ankle sprains occurred in 90% of the women's injuries, and muscle sprains occurred in 54.5% of the men's injuries. The most frequent injury location was the ankle joint in both sexes among the professional dancers, with 67.6% in women and 40.9% in men. The identification of the mechanism of injury and time of practice may contribute to better therapeutic action aimed at the proper function of the dancers' bodies and improved performance by these athletes.

    Human papillomaviruses (HPVs) cause cervical cancer and are associated with the development of non-melanoma skin cancer. A suitable animal model for papillomavirus-associated skin carcinogenesis is the infection of domestic rabbits with the cottontail rabbit papillomavirus (CRPV). As the immortalizing activity of CRPV genes in the natural target cells remains unknown, we investigated the properties of CRPV E6 and E7 in rabbit keratinocytes (RK) and their influence on the cell cycle. Interestingly, CRPV E7 immortalized RK after a cellular crisis but showed no such activity in human keratinocytes. Co-expressed CRPV E6 prevented cellular crisis. The HPV16 or CRPV E7 protein reduced rabbit pRb levels thereby causing rabbit p19 ARF induction and accumulation of p53 without affecting cellular proliferation. Both CRPV E6 proteins failed to degrade rabbit p53 in vitro or to bind E6AP; however, p53 was still inducible by mitomycin C. In summary, CRPV E7 immortalizes rabbit keratinocytes in a species-specific manner and E6 contributes to immortalization without directly affecting p53

  7. Concentration of acrylamide in a polyacrylamide gel affects VP4 gene coding assignment of group A equine rotavirus strains with P[12] specificity

    2010-01-01

    Background It is universally acknowledged that genome segment 4 of group A rotavirus, the major etiologic agent of severe diarrhea in infants and neonatal farm animals, encodes outer capsid neutralization and protective antigen VP4. Results To determine which genome segment of three group A equine rotavirus strains (H-2, FI-14 and FI-23) with P[12] specificity encodes the VP4, we analyzed dsRNAs of strains H-2, FI-14 and FI-23 as well as their reassortants by polyacrylamide gel electrophoresis (PAGE) at varying concentrations of acrylamide. The relative position of the VP4 gene of the three equine P[12] strains varied (either genome segment 3 or 4) depending upon the concentration of acrylamide. The VP4 gene bearing P[3], P[4], P[6], P[7], P[8] or P[18] specificity did not exhibit this phenomenon when the PAGE running conditions were varied. Conclusions The concentration of acrylamide in a PAGE gel affected VP4 gene coding assignment of equine rotavirus strains bearing P[12] specificity. PMID:20573245

    The solid solutions Sr{sub 2}Gd{sub 6.8}Eu{sub 1.2}Si{sub 6(1−x)}P{sub 6x}O{sub 26−δ} (where x=0–0.15 and δ is oxygen nonstoichiometry) were synthesized. The structural properties of the crystal lattice of the solid solutions and the peculiarities of Eu{sup 3+} and P{sup 5+} dopants substitution for matrix ions have been considered. The photo-, X-ray and pulsed cathode luminescence properties have been studied. It has been found that substitution of (SiO{sub 4}){sup 4−} by (PO{sub 4}){sup 3−} tetrahedron in Eu{sup 3+}-doped oxyapatites does not bring significant changes to bands structure Eu{sup 3+} in luminescence spectra under different excitation (UV, X-ray, pulse cathode beam). However, the increase of P{sup 5+} concentration in Sr{sub 2}Gd{sub 6.8}Eu{sub 1.2}Si{sub 6(1−x)}P{sub 6x}O{sub 26–δ} compounds leads to a decrease of integral intensity of Eu{sup 3+} luminescence bands due to local environment symmetry modifications and covalency degree changes. Two nonequivalent optical Eu{sup 3+} centers have been found. These compounds are of interest for efficient X-ray phosphors, display devices and LED engineering material creation. - Highlights: • The luminescence properties were studied upon UV, X-ray and pulse cathode beam. • P{sup 5+} doping of Sr{sub 2}Gd{sub 6.8}Eu{sub 1.2}Si{sub 6}O{sub 26} leads to luminescence intensity reduction. • At least two types of optical centers formed by Eu{sup 3+} ions were found. • The structural features of Sr{sub 2}Gd{sub 6.8}Eu{sub 1.2}Si{sub 6(1−x)}P{sub 6x}O{sub 26} were reported. • Partial replacement of Si by P does not change the Sr{sub 2}Gd{sub 6.8}Eu{sub 1.2}Si{sub 6}O{sub 26} structure.

    The purpose of this paper is to describe the process used to initiate research capacity building in a community of practice (CoP) focused on the research and evaluation of inter-professional education and collaboration. This CoP, composed of members from across Canada, is a committee of the Canadian Interprofessional Health Collaborative (CIHC), a national collaborative that aims to advance inter-professional education and collaboration in healthcare. The committee mapped recommendations that emerged from a number of CIHC reports onto a research capacity building framework. The expertise of the diverse members in conjunction with this unique mapping process allowed the committee to identify its long-term research and evaluation objectives and strategies. This resulted in the formation of three working groups, each tasked with activities that contribute to the committee's overall goal of building research capacity in inter-professional education and collaboration. A framework provides a structured approach to identifying research and evaluation priorities and objectives. Furthermore, the process of applying the framework engages the committee members in determining the course of action. The process can be easily transferred to other areas in need of research capacity building.

    The prevention of estrogen receptor-negative (ER-) breast cancer remains a major challenge in the cancer prevention field, although antiestrogen and aromatase inhibitors have shown adequate efficacy in preventing estrogen receptor-positive (ER + ) breast cancer. Lack of commonly expressed, druggable targets is a major obstacle for meeting this challenge. Previously, we detected the activation of Akt signaling pathway in atypical hyperplasic early-stage lesions of patients. In the current study, we found that Akt and the downstream 70 kDa ribosomal protein S6 kinase (p70S6K) signaling pathway was highly activated in ER - premalignant breast lesions and ER - breast cancer. In addition, p70S6K activation induced transformation of ER - human mammary epithelial cells (hMEC). Therefore, we explored the potential of targeting Akt/p70S6K in the p70S6K activated, ER - hMEC models and mouse mammary tumor models for the prevention of ER - breast cancer. We found that a clinically applicable Akt/p70S6K dual inhibitor, LY2780301, drastically decreased proliferation of hMECs with ErbB2-induced p70S6K activation via Cyclin B1 inhibition and cell-cycle blockade at G 0 -G 1 phase, while it did not significantly reverse the abnormal acinar morphology of these hMECs. In addition, a brief treatment of LY2780301 in MMTV- neu mice that developed atypical hyperplasia (ADH) and mammary intraepithelial neoplasia (MIN) lesions with activated p70S6K was sufficient to suppress S6 phosphorylation and decrease cell proliferation in hyperplasic MECs. In summary, targeting the aberrant Akt/p70S6K activation in ER - hMEC models in vitro and in the MMTV- neu transgenic mouse model in vivo effectively inhibited Akt/S6K signaling and reduced proliferation of hMECs in vitro and ADH/MIN lesions in vivo , indicating its potential in prevention of p70S6K activated ER - breast cancer.

    The M6 working group had more than 40 active participants (listed in Section 4). During the three weeks at Snowmass, there were about 50 presentations, covering a wide range of topics associated with high intensity proton sources. The talks are listed in Section 5. This group also had joint sessions with a number of other working groups, including E1 (Neutrino Factories and Muon Colliders), E5 (Fixed-Target Experiments), M1 (Muon Based Systems), T4 (Particle Sources), T5 (Beam dynamics), T7 (High Performance Computing) and T9 (Diagnostics). The M6 group performed a survey of the beam parameters of existing and proposed high intensity proton sources, in particular, of the proton drivers. The results are listed in Table 1. These parameters are compared with the requirements of high-energy physics users of secondary beams in Working Groups E1 and E5. According to the consensus reached in the E1 and E5 groups, the U.S. HEP program requires an intense proton source, a 1-4 MW Proton Driver, by the end of this decade.

    Full Text Available According to the WHO (World Health Organization and the European Union, suicide is considered to be a health problem of prime importance and to be one of the principal causes of unnatural death. In Spain, the number of suicides has increased 12% since 2005 . The Research Project “European Regions Enforcing Actions against Suicide (EUREGENAS, funded by the Health Program 2008-2013, has as main objective the description of an integrated model of Mental Health orientated to the prevention of suicide. The differences that allow distinguishing the meaning of prevention in suicide behavior are described and explained through a qualitative methodological strategy and through the creation of discussion groups formed by different groups of health professionals. The results highlight the existing differences between the diverse health professionals who come more in contact with this problem and it shows as well the coincidence of meaning that suicide has to be considered as a priority in the field of health.

  15. Computing Galois Groups of Eisenstein Polynomials Over P-adic Fields

    Milstead, Jonathan

    The most efficient algorithms for computing Galois groups of polynomials over global fields are based on Stauduhar's relative resolvent method. These methods are not directly generalizable to the local field case, since they require a field that contains the global field in which all roots of the polynomial can be approximated. We present splitting field-independent methods for computing the Galois group of an Eisenstein polynomial over a p-adic field. Our approach is to combine information from different disciplines. We primarily, make use of the ramification polygon of the polynomial, which is the Newton polygon of a related polynomial. This allows us to quickly calculate several invariants that serve to reduce the number of possible Galois groups. Algorithms by Greve and Pauli very efficiently return the Galois group of polynomials where the ramification polygon consists of one segment as well as information about the subfields of the stem field. Second, we look at the factorization of linear absolute resolvents to further narrow the pool of possible groups.

  16. From IPv4 to eternity - the HEPiX IPv6 working group

    2012-01-01

    The much-heralded exhaustion of the IPv4 networking address space has finally started. While many of the research and education networks have been ready and poised for years to carry IPv6 traffic, there is a well-known lack of academic institutes using the new protocols. One reason for this is an obvious absence of pressure due to the extensive use of NAT or that most currently still have sufficient IPv4 addresses. More importantly though, the fact is that moving your distributed applications to IPv6 involves much more than the routing, naming and addressing solutions provided by your campus and national networks. Application communities need to perform a full analysis of their applications, middleware and tools to confirm how much development work is required to use IPv6 and to plan a smooth transition. A new working group of HEPiX (http://www.hepix.org) was formed in Spring 2011 to address exactly these issues for the High Energy Physics community. The HEPiX IPv6 Working Group has been investigating the ma...

    Full Text Available Objective: The purpose of this study was to identify the effect of two psychological interventions, named ‘Mental imagery’ and ‘Motivational self-talk’ training used in combination, on perceived excertion and flow state in a sample of Swimrun semi-professional athletes. Methods: Thirty male semi-professional athletes, enrolled for a Swimrun competition, were randomly selected into an experimental group (EXP and a control group (CON. The modified Borg Scale of Perceived Exertion (RPE and the Flow State Scale (FSS were the dependent variables. Before a Swimrun competition, the EXP Group performed both physical and mental training programs, while the CON group only performed a physical training program. Immediately after the race, we measured the dependent variables in both groups. Results: The results of unpaired-t test showed that levels of perceived exertion were less in EXP group than CON group, (t(28 = 12.87, P < .001, while levels of flow state were higher in EXP group than CON group (t(28 = 5.96, P < .001, immediately after the end of the endurance competition. The use of both mental imagery and self-talk training in order to reduce perceived exertion and improve flow state was supported (P < .001. Discussion and Conclusion: The findings of this study support the psychobiological model of endurance performance. Our research is the first to demonstrate that mental imagery used in combination with motivational self-talk can reduce the perceived exertion and improve the flow state in Swimrun athletes during their endurance performance.

    Self-assembled monolayers (SAMs) of 6-mercaptopurine (6MP) have been prepared on a Au(111) single-crystal electrode by immersion of the metal surface in a 100 microM 6MP and 0.01 M HClO4 solution. The 6MP-SAM Au(111) single-crystal electrodes were transferred to the cell and allowed to equilibrate with the different aqueous working solutions before the electrochemical experiments. The influence of the solution pH was studied by cyclic voltammetry, double layer capacitance curves, and electrochemical impedance spectroscopy. The electrochemical behavior of the 6MP-SAM in acetic acid at pH 4 presents important differences in comparison to that obtained in 0.1 M KOH solutions. Cyclic voltammograms for the reductive desorption process in acid medium are broad and show some features that can be explained by a phase transition between a chemisorbed and a physisorbed state of the 6MP molecules. The low solubility of these molecules in acid medium could explain this phenomenon and the readsorption of the complete monolayer when the potential is scanned in the positive direction. The variation of the double-layer capacitance values in the potential range of monolayer stability with the pH suggests that the acid-base chemistry of the 6MP molecules is playing a role. This fact has been studied by following the variations of the electron-transfer rate constant of the highly charged redox probes as are Fe(CN)(6)-3/-4 and Ru(NH3)(6)+3/+2 as a function of solution pH. The apparent surface pKa value for the 6MP-SAM (pKa approximately 8) is explained by the total conversion of the different 6MP tautomers that exist in solution to the thiol species in the adsorbed state.

    Adequate nutrient intake is important to support training and to optimise performance of elite athletes. Nutritional knowledge has been shown to play an important role in adopting optimal nutrition practices. The aim of the present study was to investigate the relationship between the level of nutritional knowledge and dietary habits in elite English rugby league players using the eatwell plate food categories. General nutritional knowledge questionnaires were collected during the Super League competitive season in the first team squad of 21 professional Rugby league players (mean age 25 ± 5 yrs, BMI 27 ± 2.4 kg/m2, experience in game 6 ± 4 yrs). According to their nutritional knowledge scores, the players were assigned to either good or poor nutritional knowledge group (n = 11, n = 10, respectively). Their dietary habits were assessment using a food frequency questionnaire. The findings revealed that nutritional knowledge was adequate (mean 72.82%) in this group of athletes with the highest scores in dietary advice section (85.71%), followed by food groups (71.24%) and food choice (69.52%). The majority of athletes were not aware of current carbohydrate recommendations. This translated into their dietary habits as many starchy and fibrous foods were consumed only occasionally by poor nutritional knowledge group. In terms of their eating habits, the good nutritional knowledge group consumed significantly more fruit and vegetables, and starchy foods (p Nutritional knowledge was positively correlated to fruit and vegetables consumption (rs = .52, p nutritional knowledge in professional rugby league players with the exception of recommendation for starchy and fibrous foods. Players who scored higher in nutritional knowledge test were more likely to consume more fruits, vegetables and carbohydrate-rich foods.

    Myocardial sympathetic neural function in professional athletes who had the long-term tremendous cardiac load has not been fully investigated by myocardial iodine-123-metaiodobenzylguanidine (MIBG) uptake in comparison with power spectral analysis (PSA) in electrocardiography. Eleven male professional cycle racers and age-matched 11 male healthy volunteers were enrolled in this study. The low frequency components in the power spectral density (LF), the high frequency components in the power spectral density (HF), the LF/HF ratio and mean R-R interval were derived from PSA and time-domain analysis of heart rate variability in electrocardiography. The mean heart-to-mediastinum uptake ratio (H/M ratio) of the MIBG uptake, in professional cycle racers was significantly lower than that in healthy volunteers (p<0.01) and HF power in professional cycle racers was significantly higher than that in healthy volunteers (p<0.05). In the group of professional cycle racers, the H/M ratio showed a significant correlation with the R-R interval, as indices of parasympathetic nerve activity (r=0.80, p<0.01), but not with the LF/HF ratio as an index of sympathetic nerve activity. These results may indicate that parasympathetic nerve activity has an effect on MIBG uptake in a cyclist's heart. (author)

    Control of Aedes albopictus, major dengue and chikungunya vector, is threatened by growing cases of insecticide resistance. The mechanisms driving this resistance remain poorly characterised. This study investigated the molecular basis of insecticide resistance in Malaysian populations of Ae. albopictus. Microarray-based transcription profiling revealed that metabolic resistance (cytochrome P450 up-regulation) and possibly a reduced penetration mechanism (consistent over-expression of cuticular protein genes) were associated with pyrethroid resistance. CYP6P12 over-expression was strongly associated with pyrethroid resistance whereas CYP6N3 was rather consistently over-expressed across carbamate and DDT resistant populations. Other detoxification genes also up-regulated in permethrin resistant mosquitoes included a glucuronosyltransferase (AAEL014279-RA) and the glutathione-S transferases GSTS1 and GSTT3. Functional analyses further supported that CYP6P12 contributes to pyrethroid resistance in Ae. albopictus as transgenic expression of CYP6P12 in Drosophila was sufficient to confer pyrethroid resistance in these flies. Furthermore, molecular docking simulations predicted CYP6P12 possessing enzymatic activity towards pyrethroids. Patterns of polymorphism suggested early sign of selection acting on CYP6P12 but not on CYP6N3. The major role played by P450 in the absence of kdr mutations suggests that addition of the synergist PBO to pyrethroids could improve the efficacy of this insecticide class and overcome resistance in field populations of Ae. albopictus.

    The Astronomy Department and McDonald Observatory at the University of Texas at Austin has and continues to offer a suite of different astronomy based K-12 teacher professional development programs. One of our longest running, and most successful programs, is reaching its 20th anniversary, the EXES Teacher Associate Program, which was started in 1998. The EXES Teacher Associate program features sustained and continued professional development opportunities for K-12 science and math educators. It consists of 6 times per year day-long meetings, coupled with other professional development opportunities provided at various times. In total, there are approximately 30 active members of the group currently, but more than 90 teachers have participated in this group over its 20 year history. The program has had astronomy education as its focus throughout its history, but different partnerships and collaborations with other programs have supported the group and have allowed for a variety of professional development opportunities and themes for educators to engage in. We will give an overview of this program, present evaluation data and teacher feedback related to program success and student impact, and highlight a few specific program opportunities that are unique and have been shown to be most impactful for participants.

    We previously showed that nucleotide P2 receptor agonists such as ATP and UTP amplify γ-ray-induced focus formation of phosphorylated histone H2A variant H2AX (γH2AX), which is considered to be an indicator of DNA damage so far, by activating purine P2Y_6 and P2Y_1_2 receptors. Therefore, we hypothesized that these P2 receptors play a role in inducing the repair response to γ-ray-induced DNA damage. In the present study, we tested this idea by using human lung cancer A549 cells. First, reverse-transcription polymerase chain reaction (RT-PCR) showed that P2Y_6 receptor is highly expressed in A549 cells, but P2Y_1_2 receptor is only weakly expressed. Next, colony formation assay revealed that P2Y_6 receptor antagonist MRS2578 markedly reduced the survival rate of γ-ray-exposed A549 cells. The survival rate was also significantly reduced in P2Y_6-knock-down cells, compared with scramble siRNA-transfected cells. Since it has reported that phosphorylation of ERK1/2 after activation of EGFR via P2Y_6 and P2Y_1_2 receptors is involved in the repair response to γ-ray-induced DNA damage, we next examined whether γ-ray-induced phosphorylation of ERK1/2 was also inhibited by MRS2578 in A549 cells. We found that it was. Taken together, these findings indicate that purinergic signaling through P2Y_6 receptor, followed by ERK1/2 activation, promotes the cellular repair response to γ-ray-induced DNA damage. (author)

    We report the observation of three p-wave Feshbach resonances of 6 Li atoms in the lowest hyperfine state f=1/2. The positions of the resonances are in good agreement with theory. We study the lifetime of the cloud in the vicinity of the Feshbach resonances and show that, depending on the spin states, two- or three-body mechanisms are at play. In the case of dipolar losses, we observe a nontrivial temperature dependence that is well explained by a simple model

    The roles of group participation and group performance feedback were examined as antecedents of group potency, i.e., beliefs shared among a work group's members about the general effectiveness of the work group. Also examined were how group participation and the congruence of the feedback received from different sources about performance predicted convergence in members' beliefs about group effectiveness. The sample comprised 61 work groups of professionals involved in Master in Business Administration (MBA) programs (284 participants). Mean group size was 4.6 members (SD = .58). 65% of participants were male, and 51% were between 30 and 40 years of age. Data were gathered at two measurement times. Increases in group participation were positively related to increases in group potency and the convergence in beliefs about group effectiveness among group members over time. Results supported the premise that group performance feedback is an antecedent of changes in group potency over time.

  10. Cauliflower mosaic virus protein P6 inhibits signaling responses to salicylic acid and regulates innate immunity.

    Andrew J Love

    Full Text Available Cauliflower mosaic virus (CaMV encodes a multifunctional protein P6 that is required for translation of the 35S RNA and also acts as a suppressor of RNA silencing. Here we demonstrate that P6 additionally acts as a pathogenicity effector of an unique and novel type, modifying NPR1 (a key regulator of salicylic acid (SA- and jasmonic acid (JA-dependent signaling and inhibiting SA-dependent defence responses We find that that transgene-mediated expression of P6 in Arabidopsis and transient expression in Nicotiana benthamiana has profound effects on defence signaling, suppressing expression of representative SA-responsive genes and increasing expression of representative JA-responsive genes. Relative to wild-type Arabidopsis P6-expressing transgenics had greatly reduced expression of PR-1 following SA-treatment, infection by CaMV or inoculation with an avirulent bacterial pathogen Pseudomonas syringae pv tomato (Pst. Similarly transient expression in Nicotiana benthamiana of P6 (including a mutant form defective in translational transactivation activity suppressed PR-1a transcript accumulation in response to Agrobacterium infiltration and following SA-treatment. As well as suppressing the expression of representative SA-regulated genes, P6-transgenic Arabidopsis showed greatly enhanced susceptibility to both virulent and avirulent Pst (titres elevated 10 to 30-fold compared to non-transgenic controls but reduced susceptibility to the necrotrophic fungus Botrytis cinerea. Necrosis following SA-treatment or inoculation with avirulent Pst was reduced and delayed in P6-transgenics. NPR1 an important regulator of SA/JA crosstalk, was more highly expressed in the presence of P6 and introduction of the P6 transgene into a transgenic line expressing an NPR1:GFP fusion resulted in greatly increased fluorescence in nuclei even in the absence of SA. Thus in the presence of P6 an inactive form of NPR1 is mislocalized in the nucleus even in uninduced plants

    A measurement of the 6{sup 2}P{sub ½} --> 7{sup 2}P{sub ½} forbidden magnetic dipole matrix element in atomic thallium is described. A pulsed, linearly polarized dye laser tuned to the transition frequency is used to excite the thallium vapor from the 6{sup 2}P{sub ½} ground state to the 7{sup 2}P{sub ½} excited state. Interference between the magnetic dipole M1 amplitude and a static electric field induced E1 amplitude results in an atomic polarization of the 7{sup 2}P{sub ½} state, and the subsequent circular polarization of 535 nm fluorescence. The circular polarization is seen to be proportional to / as expected, and measured for several transitions between hyperfine levels of the 6{sup 2}P{sub ½} and 7{sup 2}P{sub ½} states.

    Firefighters perform many tasks which require a high level of fitness and their personal safety may be compromised by the physiological aging process. The aim of the study was to evaluate strength (bench-press), power (countermovement jump), sprint (20 m) and endurance (with and without Self Contained Breathing Apparatus - S.C.B.A.) of 161 Italian firefighters recruits in relation to age groups (profile for each parameter and to assess differences (p < 0.05) among age groups. Anthropometric values showed an age-effect for height and BMI, while performances values showed statistical differences for strength, power, sprint tests and endurance test with S.C.B.A. Wearing the S.C.B.A., 14% of all recruits failed to complete the endurance test. We propose that the firefighters should participate in an assessment of work capacity and specific fitness programs aimed to maintain an optimal fitness level for all ages.

    Full Text Available Introduction: Today, development of professionalism is a critical aim of medical schools. Studies have demonstrated that medical students’ perceived level of professionalism is inadequate worldwide. This study aimed to investigate the medical students’ perceptions of their colleagues’ professional behavior. Methods: This study is a cross-sectional study with 280 medical students at Shiraz University of Medical Sciences in their fifth to seventh year of study as the sample. The study was performed during one month in 2013, using stratified random sampling method. The instrument of the study was the Persian version of the questionnaire of the American Board of Internal Medicine (ABIM.The questionnaire includes demographic information, questions about the meaning of the professionalism, history of medical ethics education programs and 12 behavioral questions. The data were analyzed using student t-test and Pearson correlation test. The significance level was set as 0.05. Results: Forty percent of respondents did not know the meaning of professionalism. The mean±SD score of behavioral questions was 5.91±1.2 on a scale from 0 to 10. The mean±SD score of excellence questions was 4.94±1.7. It was 7.05±1.9 for ‘honor/integrity’, and 6.07±2.1 for ‘altruism/respect’ questions. There was a significant association between gender and excellence score (p=0.007. Conclusion: Medical students assessed their colleagues’ professional behavior as poor. They did not have proper information about professionalism. Medical students are future general practitioners and respecting medical ethics by them is very important in a perfect health system. Universities should emphasize the importance of teaching professionalism to medical students and faculty members, using innovative education methods.

    The reasons for nurse practitioners to develop a professional network are boundless and are likely to change over time. Networking opens doors and creates relationships that support new opportunities, personal development, collaborative research, policy activism, evidence-based practice, and more. Successful professional networking involves shared, mutually beneficial interactions between individuals and/or individuals and groups, regardless of whether it occurs face to face or electronically. This article combines nuggets from the literature with guidance based on the authors' combined experience in networking activities at the local, national, and international levels. ©2017 American Association of Nurse Practitioners.

    This study investigated prevalence, types and predictors of professional service use in families of children identified with attention deficit hyperactivity disorder (ADHD) in the community. children with ADHD were identified through 43 schools using parent and teacher screening questionnaires (Conners 3 ADHD Index) followed by case confirmation using the Diagnostic Interview Schedule for Children Version IV. Parents completed a survey about professional service use in the last 12 months. data on variables potentially associated with service use were collected from parents (interview and questionnaires), teachers (questionnaires) and children (direct assessment). Logistic regression was used to examine predictors of service use in univariate and multivariable analyses. The sample comprised 179 children aged 6-8 years with ADHD. Over one-third (37%) had not received professional services in the last 12 months. The strongest predictors of service use were older child age (adjusted OR=3.0, 95% CI 1.0 to 8.9, p=0.05), and the degree to which the child's behaviour impacted on the family (adjusted OR=2.0, 95% CI 1.3 to 3.3, p=0.007), after controlling for ADHD subtype and severity, externalising comorbidities, academic achievement and parent-reported impairment. A substantial proportion of children with ADHD are not accessing professional services. Our findings suggest that the child's age and the impact of the child's behaviour on the family are the strongest predictors of service use. Given the demonstrated benefits from various interventions in ADHD, there is a need to improve case identification and referral for services. Published by the BMJ Publishing Group Limited.

    Fibrates are a group of peroxisome proliferator-activated receptor α agonists used in the treatment of dyslipidemia; however, they have been reported to cause species-related hepatocarcinogenesis and clinical myotoxicity. Gemfibrozil is one of the most commonly used fibrates, and it shows the highest risk for myotoxicity among the fibrates. The inhibitory drug-drug interaction mechanism associated with gemfibrozil has been explored recently, and the induction of human P450 3A4 and 2C8 has been reported. In this study, in vivo induction of rat P450 by gemfibrozil was studied in Sprague-Dawley rats. After the rats were dosed with gemfibrozil by oral gavage, microsomes were prepared. The metabolic activities of P450 3A1/2, 2C6, and 2D2 were assayed using probe substrates, and the systemic concentration of gemfibrozil during its administration was determined. P450 3A1/2 and 2C6 activities were induced 32-77% in the rats by gemfibrozil when the exposure concentration was in the clinical range. These data indicate that the inducibility of homologous P450 isoforms by gemfibrozil is similar in Sprague-Dawley rats and in humans. Inductive drug-drug interactions and inhibitory actions are involved in the co-administration of gemfibrozil with other drugs, which suggests the relevance for a fibrate-toxicology investigation.

  17. Renormalization group approach to a p-wave superconducting model

    2014-01-01

    We present in this work an exact renormalization group (RG) treatment of a one-dimensional p-wave superconductor. The model proposed by Kitaev consists of a chain of spinless fermions with a p-wave gap. It is a paradigmatic model of great actual interest since it presents a weak pairing superconducting phase that has Majorana fermions at the ends of the chain. Those are predicted to be useful for quantum computation. The RG allows to obtain the phase diagram of the model and to study the quantum phase transition from the weak to the strong pairing phase. It yields the attractors of these phases and the critical exponents of the weak to strong pairing transition. We show that the weak pairing phase of the model is governed by a chaotic attractor being non-trivial from both its topological and RG properties. In the strong pairing phase the RG flow is towards a conventional strong coupling fixed point. Finally, we propose an alternative way for obtaining p-wave superconductivity in a one-dimensional system without spin–orbit interaction.

    To describe magnetic resonance imaging (MRI) characteristics of soleus muscle injuries in symptomatic professional football players stratified according to both the Munich consensus statement and the British Athletics Muscle Injury Classification (BAMIC), and to investigate the association between specific MRI features and the ''return to play'' (RTP). Professional football players with an episode of acute posterior calf pain and impaired function, subsequent to sports activity, underwent ultrasound followed by MRI examination reviewed by two different radiologists with more than 10 years of experience in the musculoskeletal system. MRI features and RTP outcome were evaluated for all types of injuries. During a 36-month period, a total of 20 professional football players were evaluated. According to the Munich consensus, 11 were type 3A, 8 were type 3B, and 1 was type 4, whereas according to the BAMIC, 11 lesions were considered grade 1, 4 grade 2, 4 grade 3, and 1 grade 4. RTP data were available for all patients (mean 3.3 ± 1.6 weeks). Both the Munich consensus and the BAMIC correlated with RTP (Spearman correlation = 0.982 and p < 0.0001 and 0.886 and p < 0.0001 respectively). Extension of edema was an independent prognostic factor for RTP in two different models of multivariate regression analysis (p = 0.044 model A; p = 0.031 model B). The Munich consensus and BAMIC grading systems are useful tools for defining the patient's prognosis and proper rehabilitation time after injury. The MRI feature that we should carefully look for is the extension of edema, as it seems to significantly affect the RTP. (orig.)

    Professional commitment is defined as a belief in and acceptance of the values of the profession which is chosen, effort to actualize these values, desire to improve him/herself. Nurses' professional and organizational commitment are influenced by factors such as job stress, job satisfaction and burnout. This study was conducted to determine the effect of nursing internship program on professional commitment and burnout of senior nursing students. A quasi-experimental study with a pretest and posttest without control group design was used. Students who were attending nursing internship program and agreed to participate were included in the study. Sample consisted of 101 students. Data were collected with a questionnaire, the burnout measure short version and nursing professional commitment scale. After the nursing internship, 77.2% were pleased to study nursing, 83.2% were pleased to be a senior student, 55.4% did not have any intention to change their profession, 81.2% wanted to work as nurses, and 82.2% were planning career advancement in nursing of the students, 34.7% and 43.6% were found to experience burnout, before and after the nursing internship, respectively (p nursing professional commitment scale were compared, a significant difference was found between mean scores on the total score and "maintaining membership" subscale (p nursing internship, burnout and professional commitment levels of the students increased.

    Due to inaccessibility to NJOY, steps were taken to create WIMS library, which can be extracted from ENDF/B6 without using NJOY. In addition to using preprocessing codes few programs were written to calculate integral resonance, slowing down power per unit lethargy, potential scattering, and differential scattering cross section, scattering matrices. For neutrons with energy above 4 eV, isotropic elastic scattering was assumed. For neutrons below 4 eV the free gas model was used, except for light elements, which tabulated values of S(α,β) in ENDF/B6 used. The Goldstein-Cohen factors are taken from WIMKAL88.Lib. The integral resonance with self absorption per unit lethargy was obtained from GROUPIE output. The P 1 scattering matrices are calculated only for four elements, namely H, D, C and O at 300 K. In order to examine the created libraries, k eff , δ 28 , ρ 28 , ρ 25 and CR are calculated using new WIMS library, WIMKAL88.Lib and NEA329.Lib. The results showed general agreement. The controversial issue of WIMS library group structure, particularly in resonance region has raised the question of whether the number of resonance group i.e., 13 is optimized. We generated different WIMS libraries consisting of 5, 8, 13, 18 and 23 resonance groups. The main aim was to examine the effect to resonance group structure on calculated core parameters, mainly, k eff , δ 28 , ρ 28 , ρ 25 and CR. These parameters are also calculated and compared with those obtained using WIMKAL88, and NEA329 libraries. (author)

    Full Text Available Based on a research carried out with a group of black women enrolled in the II Course for Professional Formation of Mulatas, the article recovers and analyses the categories through which the students represent their condition of mulatta and their passing to the condition of professional mulata. The mulata, who represents and mediates a Brazilian way of being a woman, sensual and race-mixed, the professional mulata debates herself, permanently, between two poles which are both professional and moral: on the one hand, there is a positive pole, of being a dancer, on the other, there is a threatening and negative one, of being a prostitute.

    Deuterium exchange labelling using [Ir(COD)(Cy 3 P)(Py)]PF 6 as catalyst and deuterium gas was studied on a number of substituted acetanilides. In most cases products containing deuterium ortho to the anilide group were obtained with a high degree of enrichment. With one exception no evidence for meta, para or anilide methyl labelling was seen. The catalyst was also effective in the ortho deuteration of acetophenone, benzophenone and the β-lactam containing compound Sch 48461. (Author)

    Chromosome 6p is one of the most commonly implicated regions in the genome-wide linkage scans of schizophrenia, whereas further association studies for markers in this region were inconsistent likely due to heterogeneity. This study aimed to identify more homogeneous subgroups of families for fine mapping on regions around markers D6S296 and D6S309 (both in 6p24.3) as well as D6S274 (in 6p22.3) by means of similarity in neurocognitive functioning. A total of 160 families of patients with schizophrenia comprising at least two affected siblings who had data for 8 neurocognitive test variables of the Continuous Performance Test (CPT) and the Wisconsin Card Sorting Test (WCST) were subjected to cluster analysis with data visualization using the test scores of both affected siblings. Family clusters derived were then used separately in family-based association tests for 64 single nucleotide polymorphisms covering the region of 6p24.3 and 6p22.3. Three clusters were derived from the family-based clustering, with deficit cluster 1 representing deficit on the CPT, deficit cluster 2 representing deficit on both the CPT and the WCST, and a third cluster of non-deficit. After adjustment using false discovery rate for multiple testing, SNP rs13873 and haplotype rs1225934-rs13873 on BMP6-TXNDC5 genes were significantly associated with schizophrenia for the deficit cluster 1 but not for the deficit cluster 2 or non-deficit cluster. Our results provide further evidence that the BMP6-TXNDC5 locus on 6p24.3 may play a role in the selective impairments on sustained attention of schizophrenia. PMID:19694819

    Nonsydromic cleft lip with or without secondary clefting of the palate (CL+/{minus}P) is one of the most common birth defects. A previous linkage study concerning CL+/{minus}P and cleft palate (CP) families indicated chromosome 6p, near F13A locus, as a possible region for the presence of a clefting gene. More recently, another linkage study performed on a sample of 12 families with nonsyndromic CL+/{minus}P seemed to exclude this association. To test the hypothesis on the possible presence of a major gene on chromosome 6p, we carried out a study on a large sample (21) of CL+/{minus}P families from northeastern Italy. In conclusion, our investigation can be summarized as follows: (i) CL+/{minus}P disease appears to be heterogeneous; (ii) {approximately}66% of the pedigrees showed an autosomal dominant inheritance with incomplete penetrance; and (iii) CL+/{minus}P locus maps on 6p23 very close to or at the microsatellite marker D6S89. To verify whether the D6S89 is the closest marker to the CL+/{minus}P locus, additional examinations with new markers are underway. 19 refs., 1 fig., 1 tab.

    Although members of the Lactobacillus casei group are known to survive under acidic conditions, the underlying mechanisms of growth at acidic condition and the impact of low pH on the relative level of protein expression at the cell surface remain poorly studied. After confirming the taxonomy of L. casei strain GCRL 12 which was originally isolated from cheese and confirmed by 16S rRNA sequence analysis, the impact of acidic pH on growth rate was determined. Late log-phase cells cultured at pH 4.0 showed obvious changes in Gram staining properties while transmission electron microscopy analysis revealed evidence of structural distortions of the cell surface relative to the controls cultured at pH 6.5. When comparing cytosolic or whole cell preparations on SDS-PAGE, few changes in protein profiles were observed under the two growth conditions. However, analysis of surface protein extracted by 5M LiCl demonstrated changes in the proportions of proteins present in the molecular weight range of 10 to 80 kDa, with some proteins more dominant at pH 6.5 and other at pH 4. These data suggest that surface proteins of this strain are associated with growth and survival at low pH. The function of these proteins is subject to further investigation.

    Precision medicine has resulted in increasing complexity in the treatment of cancer. Web-based educational materials can help address the needs of oncology health care professionals seeking to understand up-to-date treatment strategies. This study aimed to assess learning styles of oncology health care professionals and to determine whether learning style-tailored educational materials lead to enhanced learning. In all, 21,465 oncology health care professionals were invited by email to participate in the fully automated, parallel group study. Enrollment and follow-up occurred between July 13 and September 7, 2015. Self-enrolled participants took a learning style survey and were assigned to the intervention or control arm using concealed alternating allocation. Participants in the intervention group viewed educational materials consistent with their preferences for learning (reading, listening, and/or watching); participants in the control group viewed educational materials typical of the My Cancer Genome website. Educational materials covered the topic of treatment of metastatic estrogen receptor-positive (ER+) breast cancer using cyclin-dependent kinases 4/6 (CDK4/6) inhibitors. Participant knowledge was assessed immediately before (pretest), immediately after (posttest), and 2 weeks after (follow-up test) review of the educational materials. Study statisticians were blinded to group assignment. A total of 751 participants enrolled in the study. Of these, 367 (48.9%) were allocated to the intervention arm and 384 (51.1%) were allocated to the control arm. Of those allocated to the intervention arm, 256 (69.8%) completed all assessments. Of those allocated to the control arm, 296 (77.1%) completed all assessments. An additional 12 participants were deemed ineligible and one withdrew. Of the 552 participants, 438 (79.3%) self-identified as multimodal learners. The intervention arm showed greater improvement in posttest score compared to the control group (0.4 points

    Preventing suicide can depend upon the ability of a range of different health professionals to make accurate suicide risk assessments and treatment plans. The attitudes that clinicians hold towards suicide prevention initiatives may influence their suicide risk assessment and management skills. This study measures a group of non-mental health professionals' attitude towards suicide prevention initiatives. Health professionals that had attended suicide prevention education showed significantly more positive attitudes towards suicide prevention initiatives. The findings in this study further support the effectiveness of educating non-mental health professionals in suicide risk awareness and management.

    This study aims to provide a physiologic profile of professional cricketers and note positional differences at the start of the 2007/08 competitive season. Fifteen participants (9 bowlers, 6 batsmen) aged 25.0 ± 5.0 years (mean ± SD) took part in this study. Participants (bowlers and batsmen) completed a series of field-based fitness assessments: body composition (sum of 7 skinfolds, 72.5 ± 16.5 and 65.5 ± 19.3 mm, respectively), flexibility (sit and reach 8.1 ± 10.3 and 6.0 ± 6.2 cm, respectively), predicted maximal oxygen uptake (multistage shuttle run, 54.1 ± 2.8 and 56.1 ± 4.5 ml-1·kg-1·min-1, respectively), upper- (medicine ball throw, 7.7 ± 0.6 and 7.0 ± 0.1 m, respectively) and lower-body strength (countermovement jump, 45.7 ± 5.8 and 43.9 ± 4.1 cm, respectively), speed (sprint 17.7 m, 2.76 ± 0.6 and 2.77 ± 0.1 s, respectively), and explosive power (repeated jump, 31.0 ± 2.0 and 34.1 ± 4.8 cm, respectively). The data provided the physical fitness profile for each player, which, compared with normative data, identified that this cohort of professional cricketers had some superior fitness parameters compared with the general population, and where applicable, were comparable with other professional athletes. In addition, after effect size calculations, the results showed that some physical fitness differences existed between playing positions. Cricket professionals possess a superior level of physical fitness and strength, and conditioning coaches should seek to progress these physical parameters and further identify position-specific physical requirements to progress the modern game.

    To determine healthcare professionals' (HCP) views of group structured education for people with newly diagnosed Type 2 diabetes. This was a qualitative study using semi-structured interviews to ascertain primary care HCPs' views and experiences of education for people with newly diagnosed Type 2 diabetes. A thematic framework method was applied to analyse the data. Participants were HCPs (N = 22) from 15 general practices in three south London boroughs. All but one HCP viewed diabetes education favourably and all identified that low attendance was a problem. Three key themes emerged from the qualitative data: (1) benefits of diabetes education, including the group mode of delivery, improved patient interactions, saving HCPs' time and improved patient outcomes; (2) factors limiting uptake of education, including patient-level problems such as access and the appropriateness of the programme for certain groups, and difficulties communicating the benefits to patients and integration of education management plans into ongoing diabetes care; and (3) suggestions for improvement, including strategies to improve attendance at education with more localized and targeted marketing and enhanced programme content including follow-up sessions and support for people with pre-existing psychological issues. Most HCPs valued diabetes education and all highlighted the lack of provision for people with different levels of health literacy. Because there was wide variation in terms of the level of knowledge regarding the education on offer, future studies may want to focus on how to help HCPs encourage their patients to attend. © 2018 Diabetes UK.

    Full Text Available The paper considers application and development of information technologies while carrying out project management in construction. Organizational and technological support of works throughout its life cycle exerts an influence on quality and efficiency of successful implementation of the construction project. In order to achieve the project goal it is necessary perfectly to organize and plan works, distribute roles and responsibilities of the project participants, regulate composition and content of the project documentation. While analyzing technical and economic indices of construction organization activity and management systems operating in these organizations, conclusion has been made that market experience in functioning of operational management systems has not been adequately applied in practice of domestic construction organizations. Thus, introduction of integrated management systems for quality, costs, time parameters pertaining to project construction, their resource support will contribute to improvement of economic situation of construction organizations. The solution consists in application of up-to-date information technologies, maximum implementation of computer systems and programs in the sphere of production, creation of application software. It has been shown that it is necessary to develop a software model that provides a possibility comprehensively to apply information technology tools for monitoring progress of construction and installation works, systematization of information technology application that allow to control key parameters of construction and installation works, improvement of system for providing actual information in project implementation process. An example of complex application of software products Primavera P6 Professional R8.3.2 and ArchiCAD 17.0.0 is given in the paper.

    The usefulness and the impact of Direct Healthcare Professional Communications (DHPCs, or 'Dear Doctor letters') in changing the clinical behaviour of physicians have been debated. Changes in the current risk communication methods should preferably be based on the preferences of the healthcare professionals, to optimize the uptake of the message. The aim of this study was to assess whether safety issues are communicated more effectively with an additional e-mail sent by the Dutch Medicines Evaluation Board (MEB) than with the DHPC only. A randomized controlled trial was conducted amongst ophthalmologists and hospital pharmacists in the Netherlands, who were the target group of a DHPC that was issued for pegaptanib, a drug that is administered intra-ocularly in patients with macular degeneration. The intervention group (N = 110) received the pegaptanib DHPC, as well as the MEB e-mail. The control group (N = 105) received the traditional paper-based DHPC only. Two weeks later, the study population received an invitation to fill out an online questionnaire. Questions were asked about the respondents' knowledge and attitude regarding the pegaptanib issue, and any action they had consequently taken. Additional questions were asked about their satisfaction with the DHPC and the e-mail, and their preferred source of such information. Forty respondents (18.6%) completed the questionnaire. Eighty-one percent of the respondents in the intervention group (N = 21) and 47% of the control group (N = 19) correctly indicated that a serious increase in intra-ocular pressure could be caused by pegaptanib injections (Fishers' exact test, p = 0.046). Nine respondents in the intervention group versus none of the control group respondents indicated that they had taken action in response to the pegaptanib safety issue (Fishers' exact test, p = 0.01). The majority of both the intervention group and the control group confirmed that they would like to receive an MEB e-mail with safety

    Sexuality usually decreases during pregnancy. To evaluate sexual behavior during pregnancy, comparing two groups. One had sexual education and the other had none. After randomizing two groups of pregnant women, they completed self-administered questionnaires regarding attitudes and sexual behavior before and during pregnancy. Sexual education was provided in one group and a second self-administered questionnaire was completed 12 weeks later. Responses were summarized using descriptive statistics. Comparison of change of sexual behavior between two groups was analyzed using chi-square and student t-tests. The change in frequency of coitus during pregnancy was compared between the sexual education group and the noneducation group. There was no statistically difference in changes of sexual behavior between the two groups. There was a reduction in frequency of coitus (90.6% vs. 94.9%, P>0.05) between the nonsexual education group and the sexual education group and no statistically significant change in mean reduction of sexual desire (8.9 vs. 4.4, P>0.05), sexual arousal (14.3 vs. 13.1, P>0.05), satisfaction from coitus (15.4 vs. 7.2, P>0.05), and orgasm from coitus (12.3 vs. 12.3, P>0.05). The change of sexual behavior during pregnancy in the sexual education group was not different from that in the nonsexual education group. © 2010 International Society for Sexual Medicine.

    Background Educating physicians and other health care professionals to identify and treat patients who drink above recommended limits is an ongoing challenge. Methods An educational Randomized Control Trial (RCT) was conducted to test the ability of a stand alone training simulation to improve the clinical skills of health care professionals in alcohol screening and intervention. The “virtual reality simulation” combines video, voice recognition and non branching logic to create an interactive environment that allows trainees to encounter complex social cues and realistic interpersonal exchanges. The simulation includes 707 questions and statements and 1207 simulated patient responses. Results A sample of 102 health care professionals (10 physicians; 30 physician assistants [PAs] or nurse practitioners [NPs]; 36 medical students; 26 pharmacy, PA or NP students) were randomly assigned to no training (n=51) or a computer based virtual reality intervention (n=51). Subjects in both groups had similar pre-test standardized patient alcohol screening skill scores – 53.2 (experimental) vs. 54.4 (controls), 52.2 vs. 53.7 alcohol brief intervention skills, and 42.9 vs. 43.5 alcohol referral skills. Following repeated practice with the simulation there were significant increases in the scores of the experimental group at 6 months post-randomization compared to the control group for the screening (67.7 vs. 58.1, pvirtual reality simulation to demonstrate an increase in the alcohol screening and brief intervention skills of health care professionals.

    Eukaryotic ribonucleases P and MRP are closely related RNA-based enzymes which contain a catalytic RNA component and several protein subunits. The roles of the protein subunits in the structure and function of eukaryotic ribonucleases P and MRP are not clear. Crystals of a complex that included a circularly permuted 46-nucleotide-long P3 domain of the RNA component of Saccharomyces cerevisiae ribonuclease MRP and selenomethionine derivatives of the shared ribonuclease P/MRP protein components Pop6 (18.2 kDa) and Pop7 (15.8 kDa) were obtained using the sitting-drop vapour-diffusion method. The crystals belonged to space group P4(2)22 (unit-cell parameters a = b = 127.2, c = 76.8 A, alpha = beta = gamma = 90 degrees ) and diffracted to 3.25 A resolution.

    The importance of effective communication skills to sustain the cancer patient quality of life (QOL) and their satisfaction with healthcare professionals is well documented. This study aims to assess the effectiveness of communication skills training (CST) of nurses for patient QOL and their satisfaction with healthcare professionals just after being diagnosed with cancer. This is a secondary analysis of a randomized controlled trial. Eight nurses, who mainly provide psychological and informational support for patients soon after they were informed of their cancer diagnosis by physicians at a cancer screening center, were randomly assigned to an experimental group attending a CST program (four nurses) or to a control group (four nurses). Eighty-nine patients with gastric, colorectal, or breast cancer were supported and assessed by either group of nurses during the study period. The effectiveness for patient QOL and their satisfaction with healthcare professionals was assessed by administering the Short Form-8 Health Survey (SF-8) and a single-item VAS three times (1 week after diagnosis: T1; 1 month after diagnosis: T2; and 3 months after diagnosis: T3). Repeated measures analysis of variance showed a group-by-time significant increase of the mental aspects of SF-8 (F=3.48; P=0.03) and satisfaction with the nurse (F=3.18; p=0.04). Our findings underscore the importance of CST for healthcare professionals to improve the QOL of patients as well as their satisfaction with these professionals.

    To evaluate the effectiveness of a Mindfulness and Self-Compassion Program on the levels of stress and burnout in Primary Care health professionals. Randomised, controlled clinical trial. Training in Mindfulness was offered to 1,281 health professionals in Navarra (Spain) Primary Care, and 48 of them accepted. The participants were randomly assigned to groups: 25 to the intervention group, and the remaining 23 to the control group. The Mindfulness and Self-Compassion training program consisted of sessions of 2.5chours/week for 8 weeks. The participants had to attend at least 75% of the sessions and perform a daily practical of 45minutes. The levels of mindfulness, self-compassion, perceived stress, and burnout were measured using four questionnaires before and after the intervention. After the intervention, the scores of the intervention group improved significantly in mindfulness (Pmindfulness P=.001; and burnout: emotional fatigue (P=.046). The comparison with the control group showed significant differences in mindfulness (Pmindfulness and self-compassion practices in the health environment. Copyright © 2017 Elsevier España, S.L.U.

    Retrospective case-control study. To quantify the athletic performance profiles after lumbar discectomy (LD) in a cohort of National Basketball Association (NBA) players in comparison with a control group of matched NBA players who did not undergo LD during the same study period. LD provides symptomatic relief and improved functional outcomes in the majority of patients as assessed by validated measures such as Oswestry Disability Index, Visual Analog Scale, and Short Form-36 (SF-36). Among professional athletes, however, the goal of lumbar HNP treated by discectomy is not only to improve functional status but also, ultimately, to return the player to preinjury athletic performance levels. No study to date has compared the athletic performance profiles before and after discectomy in professional athletes. An analysis of NBA games summaries, weekly injury reports, player profiles, and press releases was performed to identify 24 NBA players who underwent LD for symptomatic lumbar HNP between 1991 and 2007. A 1:2 case: control study was performed using players without history of lumbar HNP who were matched for age, position, experience, and body mass index as control subjects (n = 48). Paired t tests were conducted on the following parameters: games played, minutes per game, points per 40 minutes, rebounds per 40 minutes, assists per 40 minutes, steals per 40 minutes, blocks per 40 minutes, and shooting percentage. For each athletic performance outcome, between-group comparisons evaluating preindex to postindex season performance were done (index season = season of surgery). In the LD group, 18 of 24 players (75%) returned to play again in the NBA, compared with 42 of 48 players (88%, P = 0.31) in the control group. One year after surgery, between-group comparisons revealed statistically significant increase in blocked shots per 40 minutes in the LD (0.18) versus control group (-0.33; P = 0.008) and a smaller decrease in rebounds per 40 minutes in the LD (-0

    The effect of hip arthroscopy on athletic performance compared with preinjury levels for professional athletes in different sports remains unknown. In addition, while return rates have been reported for professional baseball, football, and hockey players, return rates have not been reported for professional basketball players. Professional athletes in 4 major North American sports would be able to return to their sport and preoperative level of performance at a high rate after arthroscopic hip surgery. Descriptive epidemiology study. Major League Baseball (MLB), National Basketball Association (NBA), National Football League (NFL), and National Hockey League (NHL) athletes who underwent hip arthroscopy were identified through a previously reported protocol based on public sources. Successful return to play (RTP) was defined as returning for at least 1 professional regular season game after surgery. Performance scores were calculated by use of previously established scoring systems. Each player served as his own control, with the season prior to surgery defined as baseline. To make comparisons across sports, the authors adjusted for expected season and career length differences between sports and calculated percentage changes in performance. The authors identified 227 procedures performed on 180 professional athletes between 1999 and 2016. Successful RTP was achieved in 84.6% (192/227) of the procedures. Compared with all other athletes, NBA athletes returned at a similar rate (85.7%, P ≥ .999). NFL offensive linemen returned at a significantly lower rate than all other athletes (61.1%, P = .010). NHL athletes returned at a significantly higher rate than all other athletes (91.8%, P = .048) and demonstrated significantly decreased performance during postoperative season 1 compared with baseline (-35.1%, P = .002). Lead leg surgery for MLB athletes (batting stance for hitters, pitching stance for pitchers) resulted in a 12.7% reduction in hitter performance score

    In a previous study we showed that vaccination with the native Tat protein controlled virus replication in five out of seven monkeys against challenge with the simian human immunodeficiency virus (SHIV)-89.6P cy243 and that this protection correlated with T helper (Th)-1 response and cytotoxic T lymphocyte (CTL) activity. To address the evolution of the SHIV-89.6P cy243 both in control and vaccinated infected monkeys, the sequence of the human immunodeficiency virus (HIV)-1 Tat protein and the C2-V3 Env region of the proviral-DNA-derived clones were analyzed in both control and vaccinated but unprotected animals. We also performed analysis of the T cell epitope using a predictive epitope model taking into consideration the phylogeny of the variants. Our results suggest that even though the viral evolution observed in both groups of monkeys was directed toward variations in the major histocompatibility complex (MHC)-I epitopes, in the control animals it was associated with mutational escape of such epitopes. On the contrary, it is possible that viral evolution in the vaccinated monkeys was linked to mutations that arose to keep high the viral fitness. In the vaccinated animals the reduction of epitope variability, obtained prompting the immune system by vaccination and inducing a specific immunological response against virus, was able to reduce the emergence of escape mutants. Thus the intervention of host's selective forces in driving CTL escape mutants and in modulating viral fitness appeared to be different in the two groups of monkeys. We concluded that in the vaccinated unprotected animals, vaccination with the Tat protein induced a broad antiviral response, as demonstrated by the reduced ability to develop escape mutants, which is known to help in the control of viral replication.

    To analyse the intensity of professional collaboration (IPC) between the nurses in a multidisciplinary critical area (CA) and the relationship with the workplace "intensive care unit (ICU) and special hospitalisation area (SHA)", educational level, age, and years of professional activity in CA. A cross-sectional descriptive study was conducted with 57 nurses from CA, recording socio-demographic data: age, educational level, speciality titles, years of professional activity and workday type, years of professional activity in the CA, and involvement in scientific works. Tool: Intensity of Inter-professional Collaboration Questionnaire. SPSS 20.0. The study included a total of 47 nurses (ICU/SHA), with a mean age of 35.91 (9.59) years. Almost three-quarters (74.46%) were nursing graduates with a posgraduate in ICU. Median and interquartile range of professional experience was 14 and 14.50 years, respectively, and years working in CA was 8.50 and 16 years, respectively. Just over half of them (51.10%) worked part-time, and 61.70% participated in scientific works. The mean IPC score was 61.68 (6.84), with 57.40% providing values of high IPC. The relationship between the workplace (ICU/SHA) and educational level with IPC was not statistically significant (p>.05). There are statistical significant differences between IPC with age and years of professional activity in CA (p<.05). The present study demonstrates the existence of good IPC in the CA. Younger nurses obtain a better IPC score, as well as nurses who have been working for less time in CA. Nurses with a Degree or Masters have a higher level of IPC than the rest, as well as nurses who perform professional activity combining ICU and SHA. Copyright © 2015 Elsevier España, S.L.U. y SEEIUC.

    Background Job satisfaction in health care is currently important in view of workforce shortage in the health care area. The purpose of this study was to evaluate job satisfaction in young health professionals and to identify factors possibly influencing overall job satisfaction. Methods About one year after graduating from vocational training, a total of 579 graduates from various health care professions [Nursing (N), Nursing and Geriatric Nursing; Therapy (TP), Physical therapy and Logopaedics; Diagnostics (D), Diagnostic Radiography and Biomedical Science], were invited to participate in an online-survey. Job satisfaction was assessed with the 10-item Warr-Cook-Wall (WCW) job satisfaction questionnaire. Descriptive analysis of the WCW was performed, and the impact of various factors on job satisfaction was determined by stepwise linear regression analysis. Results In total, 189 graduates (N, n=121; TP, n=32; D, n=36) were included in data analysis (32.6% response rate). Overall job satisfaction in all young professionals was 4.9±1.6 (mean±SD) and was slightly higher in TP (5.4±1.4) compared with N (4.7±1.6) and D (5.0±1.5), respectively. Highest satisfaction was identified with "colleagues" and lowest satisfaction with "income" was identified in all professional groups. Colleagues and fellow workers showed the highest score of association regarding overall job satisfaction in regression analysis. Conclusions As a whole, our data suggest good to very good satisfaction in various WCW items of job satisfaction. "Colleagues" were shown to have a high impact on job satisfaction. To improve the attractiveness of job profiles in health care, the presented results may provide a valuable input regarding workforce shortage. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background: Professionalism is a dynamic, socially constructed idea, rendering it difficult to comprehend. Though characterized by the demonstration of values and behaviors, its meaning has not been fully explored and remains tacit. To explore how first- and second-year master’s of occupational therapy students conceptualize professionalism. Method: This qualitative pilot study evolved from an interpretivist theoretical perspective. Convenience sampling yielded four first-year and seven second-year students from one entry-level master’s program to participate in two separate focus groups. Line-by-line constant comparison methods were used to analyze the data and identify categories. An audit trail, peer debriefing, and member checking were employed. Results: Data analysis of the first-year focus group generated three categories: Searching for explicit examples, Responsibility to the profession, and Building and fulfilling societal responsibility. Analysis of the second-year focus group yielded two categories: Professional values and behaviors and Professionalism as socially constructed. Conclusion: Professionalism is a dynamic concept requiring nuanced understandings specific to context. Students should be encouraged to develop reflective abilities allowing them to analyze and act in a way that is most appropriate for the situation. Understanding students’ conceptualizations of professionalism may better allow occupational therapy regulators, managers, and academic and fieldwork educators to identify teaching and research priorities.

    The kinetic processes for the Xe (6p[1/2] 0 ) atoms in Kr, Ar, Ne, and He buffer gases were studied. We found that Kr, Ar, and Ne atoms can be used to switch the amplified spontaneous emission (ASE) channel from 3408 nm (6p[1/2] 0 -6s'[1/2] 1 ) to 3680 nm (5d[1/2] 1 -6p[1/2] 1 ), while Xe and He atoms do not show such a phenomenon. This ASE channel switch is mainly ascribed to the fast transfer of 6p[1/2] 0 → 5d[1/2] 1 . On the basis of the rate equations for two-state coupling (energy-transfer processes between the two states are very rapid), the reason why the ASE channel switch effect normally coincides with a double exponential decay of the spontaneous emission at 828 nm (6p[1/2] 0 -6s[3/2] 1 ) is explained. The actual situations in Xe, Ar, Ne, and He follow this rule. However, the strictly single exponential decay of the spontaneous emission at 828 nm and strong ASE channel switch effect simultaneously emerge in Kr. This indicates that the transfer of 6p[1/2] 0 → 5d[1/2] 1 in Kr does not occur via two-state coupling, but via two steps of near-resonance collision through the 5s[3/2] 2 (Kr) state as the intermediate state (6p[1/2] 0 → 5s[3/2] 2 (Kr) → 5d[1/2] 1 ). In addition, we found Xe (6p[1/2] 0 ) atoms strongly tend to reach the 6p[3/2] 2 , 6p[3/2] 1 , and 6p[5/2] 2 states through the 5s[3/2] 2 (Kr) state as the intermediate state in Kr. The 5s[3/2] 2 (Kr) state plays a very important role in the energy-transfer kinetics for the Xe (6p[1/2] 0 ) atoms. Kr is probably an excellent buffer gas for laser systems based on Xe.

    To date, studies on the outcomes of a shared war reality among mental health professionals (MHPs) in southern Israel have focused only on those residing and working in Otef Gaza. The aim of this study is to determine the impact of different exposure levels to shared trauma on the professional quality of life of MHPs in southern Israel. This study compares the level of secondary traumatic stress, burnout, and compassion satisfaction of social workers from Otef Gaza to social workers living and working in the Beer-Sheva area who experience occasional missile attacks. The Professional Quality of Life Scale was used to examine the level of secondary traumatic stress, burnout, and compassion satisfaction of 125 social workers living and working in the Negev: 72 from Beer-Sheva and 53 from the regional councils of Otef Gaza. No statistically significant differences were found in the three professional quality of life variables between the Otef-Gaza and Beer-Sheva groups. The lack of secondary traumatic stress and burnout differences between the study groups, despite the chronic exposure to terror attacks among the Otef Gaza social workers, may be explained by the strong sense of belonging and support evidenced by many Otef Gaza residents as well as by the comprehensive trauma training MHPs receive for work in the region. The results of this study are important for health policy geared to trauma prevention efforts, moderating the effects of work under shared war reality, and promoting the professional quality of life of MHPs in conflict areas.

Here, we show using biochemistry and small-angle X-ray scattering (SAXS) that Rrp6p and Rrp47p associate into a stable, heterodimeric complex with an elongated shape consistent with binding of Rrp47p to the nuclease domain and opposite of the HRDC domain of Rrp6p. Rrp47p reduces the exonucleolytic activity of Rrp6p on both single-stranded and structured RNA substrates without significantly altering the affinity towards RNA or the ability of Rrp6p to degrade RNA secondary structure.

    The quality of health care significantly depends on the satisfaction of the employees. The objective of this study was to establish the level of professional satisfaction of healthcare professionals in state hospitals in Belgrade, Serbia, and to determine and to rank the factors which impact on their satisfaction or dissatisfaction. Professional satisfaction survey was designed and conducted as a cross-sectional study in 2008. Completed questionnaires were returned by 6,595 healthcare professionals from Belgrade's hospitals. Statistical analysis was performed using the Student's t-test, χ² test and ANOVA. Factor analysis was applied in order to define determinants of professional satisfaction, i.e. dissatisfaction. This study showed that the degree of professional satisfaction of Serbian healthcare professionals was low. The main causes of professionals'dissatisfaction were wages, equipment, the possibility of continuous medical education/training and the opportunities for professional development. Healthcare professionals with university education were more satisfied with all the individual aspects of job satisfaction than those with secondary school and college education. There were significantly more healthcare professionals satisfied with their job among males, older than 60 years, in the age group 50-59 years, with managerial function, and with 30 or more years of service. Development strategy of human resources in the Serbian health care system would significantly improve the professional satisfaction and quality of the provided health care.

    The aim of the study was to assess pH, pO2 and pCO2 in peritoneal fluid. The study was conducted on a group of 22 dogs with symptoms of ascites. Group 1 consisted of 4 dogs with adenocarcinoma, group 2--of 6 dogs with glomerulonephritis, group 3 of 8 dogs with hepatic cirrhosis and group 4 of 4 dogs with bacterial peritonitis. An abdominal cavity puncture was performed in all dogs and the fluid was drawn into a heparinized syringe in order to assess pH, pO2 and pCO2 . The analysis of pH in the peritoneal fluid revealed statistically significant differences between group 4 and groups 1 (p=0.01), 2 (p=0.01), and 3 (p=0.01). The lowest pH value compared to the other studied groups was recorded in group 4. In group 4, the pO2 was the lowest compared to the other groups (group 1 p=0.01, group 2 p=0.01, group 3 p=0.01). The value of pCO2 was the highest in group 4 compared to groups 1, 2, and 3. The study found statistically significant differences in pH, pCO2 and pCO2 between group 4 (the group of dogs with bacterial peritonitis) and the other groups of dogs. This was probably linked to the pathogenesis of peritonitis. As a result of an inflammatory reaction within the peritoneal cavity, there is an increase in fibrin accumulations leading to a decreased oxygen supply causing the oxidative glucose metabolism to change into a non-oxidative glucose metabolism. This, in turn, causes a decrease in pH, acidosis, and a low oxidoreduction potential. It also impairs phagocytosis and activates proteolytic enzymes which create ideal conditions for the growth of anaerobic bacteria. The obtained results indicate that the pH, pO2 and pCO2 may be used to differentiate bacterial peritonitis from ascites of other etiologies.

    The KAFAX-F22 was developed from JEF-2.2, which is a MATXS format, multigroup library of fast reactor. The KAFAX-F22 has 80 and 24 energy group structures for neutron and photon, respectively. It includes 89 nuclide data processed by NJOY94.38. The TRANSX/TWODANT system was used for benchmark calculations of fast reactor and one- and two-dimensional calculations of ONEDANT and TWODANT were carried out with 80 group, P 3 S 16 and with 25 group, P 3 S 8 , respectively. The average values of multiplication factors are 0.99652 for MOX cores, 1.00538 for uranium cores and 1.00032 for total cores. Various central reaction rate ratios also give good agreements with the experimental values considering experimental uncertainties except for VERA-11A, VERA-1B, ZPR-6-7 and ZPR-6-6A cores of which experimental values seem to involve some problems.
