Terms modified by Health Sciences Selected AbstractsCardiovascular Risk Factors in Subjects with Helicobacter pylori InfectionHELICOBACTER, Issue 2 2002Toshiharu Takashima Abstract Background. It has been proposed that Helicobacter pylori infection is related to cardiovascular disease, although this has not been fully investigated. The aim of this study was to investigate whether H. pylori in-fection is associated with cardiovascular risk factors. Subjects and Methods. One thousand six hundred and fifty people undergoing annual medical checks at Shimane Institute of Health Science between September 1998 and August 1999 were enrolled. Gender, age, body mass index, habitual smoking and drinking, systolic and diastolic blood pressure, serum level of total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDLC), blood glucose, leukocyte count and hemoglobin were compared between H. pylori seropositive and seronegative cases. Results. In H. pylori seropositive individuals, HDLC was significantly lower than that in seronegative individuals. After adjustment for possible confounding factors (gender, age, BMI, smoking and drinking habits), mean HDLC in H. pylori -seropositive and seronegative individuals were 56.1 and 58.2 mg/dl, respectively (p < .005). The percentage of the elderly (over 50 years old) individuals with HDLC < 35 mg/dl in H. pylori seropositive and seronegative groups were 7.4% and 4.7%, respectively (p < .001). In addition, the lower HDLC level was accompanied by an increased leukocyte count. Conclusion. Long-term infection with H. pylori may have an important role in decreasing the serum HDLC concentration. [source] The Relationship Between Leg Power and Physical Performance in Mobility-Limited Older PeopleJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2002Jonathan F. Bean Md MS OBJECTIVES: The purpose of this study was to assess the influence of leg power and leg strength on the physical performance of community-dwelling mobility-limited older people. DESIGN: Cross-sectional analysis of baseline data from a 12-week randomized controlled exercise-intervention study. SETTING: Exercise laboratory within the Department of Health Science of an urban university. PARTICIPANTS: Forty-five community-dwelling mobility-limited people (34 women, 11 men), aged 65 to 83. MEASUREMENTS: Health status, depression, cognition, physical activity, and falls efficacy; physiological measures of lower extremity strength and power; and measures of physical performance. RESULTS: Through bivariate analyses, leg power was significantly associated with physical performance as measured by stair-climb time, chair-stand time, tandem gait, habitual gait, maximal gait, and the short physical performance battery describing between 12% and 45% of the variance (R2). Although leg power and leg strength were greatly correlated (r = .89) in a comparison of bivariate analyses of strength or power with physical performance, leg power modeled up to 8% more of the variance for five of six physical performance measures. Despite limitations in sample size, it appeared that, through quadratic modeling, the influence of leg power on physical performance was curvilinear. Using separate multivariate analyses, partial R2 values for leg power and leg strength were compared, demonstrating that leg power accounted for 2% to 8% more of the variance with all measures of physical performance. CONCLUSION: Leg power is an important factor influencing the physical performance of mobility-limited older people. Although related to strength, it is a separate attribute that may exert a greater influence on physical performance. These findings have important implications for clinicians practicing geriatric rehabilitation. J Am Geriatr Soc 50:461,467, 2002. [source] Evaluation of a family-oriented continuing medical education course for general practitionersMEDICAL EDUCATION, Issue 3 2002Anja Taanila Objective To explore the long-term effects of a 2-year Family Systems Medicine course. Fifteen experienced GPs participated in the training programme. Setting Continuing Education Centre, University of Tampere, Department of Public Health Science and General Practice, University of Oulu, Finland. Methods The participants assessed the development of their professional skills on the Doherty-Baird scale and filled in 2 questionnaires. The material obtained from the application form and 2 questionnaires was analysed using the grounded theory method. Results The reasons for taking part in the course seemed to be the constant increase in the workload, problems caused by the demands for change and adaptation, stress and exhaustion. Furthermore, 10 health centres out of 15 had adopted the population-based practice, which requires different working methods compared to the old routines. Some trainees reported that their family-centred working methods improved during the course. A year after the end of the training, all of the GPs who had participated were using such methods in their daily practice. Half of the participants felt that they had also improved the functioning of their working group by making it more family-oriented. The significance of multiprofessional collaboration was one of the most important insights during the course. Conclusion The 2-year family-oriented training programme provided GPs with systemic thinking and with new skills, including the ability to work with families. The programme raised awareness of the need for multiprofessional collaboration in the primary care sittings.

The aim of this study was to estimate the prevalence of migraine and describe its clinical features and associated conditions among students of the Faculty of Health Sciences of Abomey-Calavi University, in Cotonou, Benin. Methods., A cross-sectional study was prospectively conducted during the academic year 2002-2003 and included 336 students selected using systematic random sampling. Migraine was defined according International Headache Society criteria 1988. Results., The lifetime prevalence of migraine was 11.3% (95% CI: 8.2-15.3%). The prevalence was significantly higher in females (18.3%) than males (6.8%), in married-widowed (30.4%) than single (9.9%). The mean age at onset of the disease was 15.0 years ± 2.5. Migraine without aura was the more frequent form (57.9%). The mean attack frequency per month was 3.8 (±3.4) and the peak attack duration was between 4 and 6 hours. Psychological tiredness was the most frequent triggering factors (92.1%). The factors associated with migraine in multivariate analysis were female sex (OR = 2.6 [95% CI: 1.2-5.3]), single marital status (OR = 3.7 [95% CI: 1.2-11.9]) and presence of a family history of headache (OR = 2.9 [95% CI: 1.0-8.1]) Conclusion., Migraine was frequent in students in Cotonou (Benin) compared with other studies in Africa. [source] Nursing, midwifery and allied health education programmes in AfghanistanINTERNATIONAL NURSING REVIEW, Issue 2 2005P. Herberg phd Background:, In 2001, Afghanistan was the centre of the world's attention. By 2002, following 23 years of internal conflict , including Soviet invasion, civil war and Taliban rule, plus 3 years of drought, the country was just beginning the process of re-establishing its internal structures and processes. In the health sector, this included the revival of the Ministry of Health (MOH). The MOH was assisted in its efforts by multiple partners, including the UN, donor and aid agencies, and a variety of non-governmental organizations. The author served as a consultant to the Aga Khan University School of Nursing, in partnership with the World Health Organization and the MOH, as it took on the work of strengthening nursing, midwifery and allied health education programmes for Afghanistan. Aim:, This paper will focus on the initial assessment of that sector. It will describe the situation as it existed in 2002, by examining the Kabul Institute of Health Sciences (IHS) and then turn briefly to the current state of affairs. Conclusions:, Despite the uncertainties of daily life in Afghanistan, the country has successfully initiated the reconstruction process. In the health sector, this can be seen in the work done at the Kabul IHS. Progress has been made in a number of areas, most notably in development and implementation of nursing and midwifery curricula. However, no one would deny that much more work is needed. [source] Smoothing Observational Data: A Philosophy and Implementation for the Health SciencesINTERNATIONAL STATISTICAL REVIEW, Issue 1 2006Sander Greenland Summary Standard statistical methods (such as regression analysis) presume the data are generated by an identifiable random process, and attempt to model that process in a parsimonious fashion. In contrast, observational data in the health sciences are generated by complex, nonidentified, and largely nonrandom mechanisms, and are analyzed to form inferences on latent structures. Despite this gap between the methods and reality, most observational data analysis comprises application of standard methods, followed by narrative discussion of the problems of entailed by doing so. Alternative approaches employ latent-structure models that include components for nonidentified mechanisms. Standard methods can still be useful, however, provided their modeling philosophy is modified to encourage preservation of structure, rather than achieving parsimonious description. With this modification they can be viewed as smoothing or filtering methods for separating noise from signal before the task of latent-structure modeling begins. I here give a detailed justification of this view, and a hierarchical-modeling implementation that can be carried out with popular software. Concepts are illustrated in the smoothing of a contingency table from an analysis of magnetic fields and childhood leukemia. Résumé Les méthodes statistiques standard (telles que l'analyse par régression) supposent que les données sont générées par un processus aléatoire identifiable, et tentent de modéliser ce processus d'une façon parcimonieuse. Par contraste, les données d'observation dans les sciences de la santé sont générées par des mécanismes complexes, non identifiés et largement non aléatoires, et elles sont analysées pour tirer des conclusions sur les structures latentes. En dépit de cet écart entre les méthodes et la réalité, l'analyse de la plupart des données d'observation comprend l'application des méthodes standard, suivies par la discussion narrative des problèmes engendrés par ces procédés. Les approches alternatives emploient des modèles à structure latente qui incluent des composantes pour les mécanismes non identifiés. Cependant, les méthodes standard peuvent encor être utiles, à condition que la conception de leur modélisation soit modifiée pour encourager la préservation de la structure, plutôt que d'arriver à une description parcimonieuse. Avec cette modification elles peuvent être considérées comme des méthodes de lissage ou de filtrage pour séparer le bruit du signal avant que commence le travail de modélisation à structure latente. Je donne ici une justification detaillée de cette opinion et je présente une mise en oeuvre de modélisation hiérachique qui peut être réalisée avec un logiciel courant. Les concepts sont illustrés dans le lissage d'un tableau de contingence à partir d'une analyse de champs magnétiques et de leucémie enfantine. [source] Zoogeography of the southern African ascidian faunaJOURNAL OF BIOGEOGRAPHY, Issue 12 2004Carmen Primo Abstract Aim, To describe the biogeography of the ascidian fauna of southern Africa, to compare the results obtained with those reported for other fauna and flora of the same region, and to speculate about the origin of ascidians in the region. Location, Southern Africa extending over 4000 km from Mossâmedes (15° S,12° E) to Inhaca Island (26°30, S,33° E), including Vema Seamount (31°40, S,8 °20, E), Amsterdam-Saint Paul Islands (38° S,77°30, E) and the Tristan-Gough Islands (38° S,12°20, W). Methods, We constructed a presence/absence matrix of 168 species for 26 biogeographical divisions, 21 classical biogeographical regions described by Briggs (Marine zoogeography, McGraw-Hill, New York, 1974) and five provinces within the southern African region. We considered the following limits and divisions into provinces for the southern African region: Namibia, Namaqua, Agulhas and Natal as proposed by Branch et al. (Two oceans. A guide to the marine life of southern Africa, David Philip Publishers, 1994), and the West Wind Drift Islands province (WWD) according to Briggs (Global biogeography, Elsevier Health Sciences, Amsterdam, 1995). To examine the biogeographical structure, species and divisions were classified using cluster analysis (based on UPGMA as the aggregation algorithm) with the Bray,Curtis index of similarity. This classification was combined with MDS ordination. Main conclusions, Four main groups were obtained from the analysis of affinities among species: (1) species present in the WWD, separated by a high percentage of endemisms and a low number of species with a southern African distribution. Moreover, in the light of the species distribution and the results of further analysis, which revealed that they are completely separated and not at all related to the southern African region, it appears that there are no close relationships among the different islands and seamounts of the West Wind Drift Island province. This province was therefore removed from the remaining analyses; (2) species with a wide distribution; (3) species of colder waters present in Namaqua and Agulhas provinces, a transitional temperate area in which gradual mixing and replacement of species negate previous hypotheses on the existence of a marked distributional break at Cape of Good Hope; (4) species of warmer waters related to Natal province. The classification into biogeographical components was dominated by the endemic (47%), Indo-Pacific (25%) and cosmopolitan (13%) components. The analysis of affinities among biogeographical areas separated Namibia from the rest of the southern African provinces and showed that it was related to some extent to the Antarctic region because of the cold-temperate character of the province and the low sampling effort; Namaqua, Agulhas and Natal were grouped together and found to be closely related to the Indo-West Pacific region. In general, our results were consistent with those obtained for other southern African marine invertebrates. The frequency distribution of solitary/colonial strategies among provinces confirmed the domination of colonial organisms in tropical regions and solitary organisms in colder regions. Finally, we speculate that the southern African ascidian fauna mainly comprises Indo-Pacific, Antarctic and eastern Atlantic ascidians.

Identifying women with severe angiographic coronary disease. J Intern Med 2010; 268:66,74. Objectives., To determine sex/gender differences in the distribution of risk factors according to age and identify factors associated with the presence of severe coronary artery disease (CAD). Design., We analysed 23 771 consecutive patients referred for coronary angiography from 2000 to 2006. Subjects., Patients did not have previously diagnosed CAD and were referred for first diagnostic angiography. Outcome measures., Patients were classified according to angiographic disease severity. Severe CAD was defined as left main stenosis ,50%, three-vessel disease with ,70% stenosis or two-vessel disease including proximal left anterior descending stenosis of ,70%. Univariate and multivariate logistic regression was used to assess the association between risk factors and angina symptoms with severe CAD. Results., Women were less likely to have severe CAD (22.3% vs. 36.5%) compared with men. Women were also significantly older (69.8 ± 10.6 vs. 66.3 ± 10.7 years), had higher rates of diabetes (35.0% vs. 26.6%), hypertension (74.8% vs. 63.3%) and Canadian Cardiovascular Society (CCS) class IV angina symptoms (56.7% vs. 47.8%). Men were more likely to be smokers (56.9% vs. 37.9%). Factors independently associated with severe CAD included age (OR = 1.05; 95% CI 1.05,1.05, P < 0.01), male sex (OR = 2.43; CI 2.26,2.62, P < 0.01), diabetes (OR = 2.00; CI 1.86,2.18, P < 0.01), hyperlipidaemia (OR = 1.50; CI 1.39,1.61, P < 0.01), smoking (OR = 1.10; CI 1.03,1.18, P = 0.06) and CCS class IV symptoms (OR = 1.43; CI 1.34,1.53, P < 0.01). CCS Class IV angina was a stronger predictor of severe CAD amongst women compared with men (women OR = 1.82; CI 1.61,2.04 vs. men OR = 1.28; CI 1.18,1.39, P < 0.01). Conclusions., Women referred for first diagnostic angiography have lower rates of severe CAD compared with men across all ages. Whilst conventional risk factors, age, sex, diabetes, smoking and hyperlipidaemia are primary determinants of CAD amongst women and men, CCS Class IV angina is more likely to be associated with severe CAD in women than men.

Medical ethics in the 21st century. J Intern Med 2000; 248: 1,6. Objectives. To foresee how medical ethics may develop in the 21st century. Design. We have looked into our crystal ball to see what factors are likely to drive medical ethics over the next few decades. We have given examples of how such factors might affect specific issues. Results. Those factors that we identified as likely to shape the future of medical ethics are: Globalization. Medical ethics is likely to have to grapple increasingly with ethical issues arising from the huge discrepancies in the level of health care available in different countries. Increase in longevity. We predict that there will be, at least amongst the richer nations, a significant increase in life expectancy. This will result in issues of resource allocation becoming increasingly problematic within medicine. Child enhancement. Developments in genetics combined with control of reproduction will make it possible to select our children for a broad range of characteristics. There are optimistic and pessimistic predictions as to how such power will be used. In either case, this area will be an important focus of concern in medical ethics. The biological determination of behaviour. Genetic research will lead to an increasing sense that undesirable behaviour is genetically determined. This will lead to a re-examination of such concepts as criminal responsibility. Therapeutic research and clinical practice. We predict that an increasing amount of clinical practice will be within the setting of clinical trials. The ethics of therapeutic research and clinical practice will need to be brought within a coherent framework.

Tooke JE, Hannemann MM (School of Postgraduate Medicine and Vascular Health Sciences, University of Exeter, Devon). Adverse endothelial function and the insulin resistance syndrome (Review). J Intern Med 2000; 247: 425,431. Type 2 diabetes is characterized by impaired endothelial dependent vasodilatation which may contribute to the high prevalence of vascular disease in such patients. Although hyperglycaemia, dyslipidaemia and hypertension can all independently cause a similar defect, recent data suggest that endothelial dysfunction may be intrinsic to the insulin resistance syndrome that commonly precedes type 2 diabetes. Such abnormalities in endothelial function could represent the impact of subclinical disturbance of metabolism or alternatively the presence of a common cellular defect that influences both nitric oxide bioavailability and insulin mediated glucose disposal. Resolution of this puzzle is likely to lead to important advances in our knowledge and ultimately treatment of vascular disease.

[source] Harnessing a University to address rural health workforce shortages in AustraliaAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 4 2007David Lyle Abstract Objective:,To describe the efforts of health faculties at the University of Sydney to contribute to the recruitment and retention of rural health professionals and examine for opportunities that would benefit from an institutional-led response. Design:,Cross-sectional survey. Setting:,The University of Sydney as a leading institution for health science education in New South Wales, which produces approximately 40% of all health science graduates in the state each year. Participants:,Staff responsible for course coordination within the faculties of Dentistry, Medicine, Nursing and Midwifery, and Pharmacy; and eight disciplines of the Faculty of Health Sciences. Results:,Of the two educational strategies associated with future rural employment, more progress has been made with rural placements, which were offered by all but one of the health courses. Efforts aimed at the other key strategy of attracting and supporting rural origin students were not well developed. Dentistry, Medicine, Pharmacy and only one Faculty of Health Sciences programs had more than 0.2 full-time equivalent staff to support rural initiatives. Conclusion:,Despite the significant government investment in rural health education, the University of Sydney experience demonstrates that this does not necessarily translate into adequate internal resources available for every course or program to optimise performance for rural health workforce outcomes. In an environment of competing priorities, benefits are likely to accrue from strategies that draw on the existing resource base and operate through greater collaborative action, coordinated at the institutional level. [source] Implementing a problem-based learning curriculum in occupational therapy: A conceptual modelAUSTRALIAN OCCUPATIONAL THERAPY JOURNAL, Issue 3 2000Penny Salvatori Problem-based learning in occupational therapy education has enjoyed increasing attention in recent years. Drawing on concepts from general systems theory and organizational theory, this paper presents a conceptual model of an occupational therapy education program as an open and dynamic system that interacts with and is responsive to the external environment. The model is described in the generic context of developing, implementing and evaluating a problem-based learning curriculum. The Bachelor of Health Sciences (Occupational Therapy) program at McMaster University in Canada is used to provide a practical illustration of the various components of the model. The model is considered to be sufficiently generic and adaptable for use by any occupational therapy program in any sociocultural environment in the world, and will be of particular interest to those who are considering problem-based learning as an alternative to traditional educational approaches. [source] Biochemistry of the envenomation response,A generator theme for interdisciplinary integrationBIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION, Issue 2 2010Erik Montagna Abstract The understanding of complex physiological processes requires information from many different areas of knowledge. To meet this interdisciplinary scenario, the ability of integrating and articulating information is demanded. The difficulty of such approach arises because, more often than not, information is fragmented through under graduation education in Health Sciences. Shifting from a fragmentary and deep view of many topics to joining them horizontally in a global view is not a trivial task for teachers to implement. To attain that objective we proposed a course herein described,Biochemistry of the envenomation response,aimed at integrating previous contents of Health Sciences courses, following international recommendations of interdisciplinary model. The contents were organized by modules with increasing topic complexity. The full understanding of the envenoming pathophysiology of each module would be attained by the integration of knowledge from different disciplines. Active-learning strategy was employed focusing concept map drawing. Evaluation was obtained by a 30-item Likert-type survey answered by ninety students; 84% of the students considered that the number of relations that they were able to establish as seen by concept maps increased throughout the course. Similarly, 98% considered that both the theme and the strategy adopted in the course contributed to develop an interdisciplinary view. [source] The information trail of the ,Freshman 15',a systematic review of a health myth within the research and popular literatureHEALTH INFORMATION & LIBRARIES JOURNAL, Issue 1 2008Cecelia Brown Question: ,How does health misinformation become part of the American and Canadian vernacular? Data sources and selection: ,Twenty-three databases were searched for articles discussing university freshmen weight gain. Research articles were examined for methodology, number and gender of the participants and weight gain. Popular press articles were reviewed for the types of information published: expert/anecdotal, weight gain, nutrition, exercise, health and alcohol. A timeline of article publication dates was generated. Results: ,Twenty peer-reviewed, 19 magazine, 146 newspaper, and 141 university newspaper articles were discovered. Appearance of media articles about the ,Freshman 15' mirrored the peer-reviewed articles, yet the information did not reliably depict the research. Research indicated a weight gain of less than five pounds (2.268 kg), while half of the popular press publications claimed a 15-pound (6.804 kg) weight gain. The misinformation was frequently accompanied by information about achieving weight control through diet, exercise, stress reduction and alcohol avoidance. Conclusion: ,Understanding of how the concept of the ,Freshman 15' developed indicates that remediation efforts are needed. Collaborative efforts between health science and academic librarians, faculty and journalists to construct new paradigms for the translation of scientific evidence into information that individuals can use for decisions about health and well-being is suggested. [source] A systematic review of peer teaching and learning in clinical educationJOURNAL OF CLINICAL NURSING, Issue 6 2008Jacinta Secomb Aims and objectives., The purpose of this review is to provide a framework for peer teaching and learning in the clinical education of undergraduate health science students in clinical practice settings and make clear the positive and negative aspects of this teaching and learning strategy. Background., The practice of using peers incidentally or purposefully in the clinical education of apprentice or undergraduate health science students is a well-established tradition and commonly practiced, but lacks definition in its implementation. Method., The author conducted a search of health science and educational electronic databases using the terms peer, clinical education and undergraduate. The set limitations were publications after 1980 (2005 inclusive), English language and research papers. Selection of studies occurred: based on participant, intervention, research method and learning outcomes, following a rigorous critical and quality appraisal with a purposefully developed tool. The results have been both tabled and collated in a narrative summary. Results., Twelve articles met the inclusion criteria, representing five countries and four health science disciplines. This review reported mostly positive outcomes on the effectiveness of peer teaching and learning; it can increase student's confidence in clinical practice and improve learning in the psychomotor and cognitive domains. Negative aspects were also identified; these include poor student learning if personalities or learning styles are not compatible and students spending less individualized time with the clinical instructor. Conclusions., Peer teaching and learning is an effective educational intervention for health science students on clinical placements. Preclinical education of students congruent with the academic timetable increases student educational outcomes from peer teaching and learning. Strategies are required prior to clinical placement to accommodate incompatible students or poor student learning. Relevance to clinical practice., The findings from this systematic review, although not statistically significant, do have pragmatic implications for clinical practice. It can increase clinical placement opportunities for undergraduate health students, assist clinical staff with workload pressures and increase clinician time with clients, while further developing students' knowledge, skills and attitudes. [source] From Miasma to Fractals: The Epidemiology Revolution and Public Health NursingPUBLIC HEALTH NURSING, Issue 4 2004Marjorie A. MacDonald Ph.D. Abstract If public health nursing is truly a synthesis of public health science and nursing science, then nurses must keep track of current developments in public health science. Unfortunately, the public health nursing literature has not kept pace with revolutionary developments in epidemiology, one of the sciences that informs population-focused nursing practice. Most epidemiology chapters in community health nursing texts do not reflect the intellectual development that has taken place in epidemiology over the past two decades. The purpose of this article therefore is to facilitate an updated synthesis by (a) reviewing the development of epidemiology and the focus of public health nursing practice through three historical eras, (b) discussing current controversies and tensions within epidemiology, (c) introducing an emerging paradigm in epidemiology based on an ecosocial perspective, and (d) discussing the congruence of this perspective with the evolving theory and practice of public health nursing. [source] A longitudinal evaluation of medical student knowledge, skills and attitudes to alcohol and drugsADDICTION, Issue 6 2006Gavin Cape ABSTRACT Aim To examine the knowledge, skills and attitudes of medical students to alcohol and drugs as training progresses. Design A longitudinal, prospective, cohort-based design. Setting The four schools of medicine in New Zealand. Participants All second-year medical students (first year of pre-clinical medical health sciences) in New Zealand were administered a questionnaire which was repeated in the fourth (first year of significant clinical exposure) and then sixth years (final year). A response rate of 98% in the second year, 75% in the fourth year and 34% in the sixth year, with a total of 637 respondents (47.8% male) and an overall response rate of 68%. Questionnaire The questionnaire consisted of 43 questions assessing knowledge and skills,a mixture of true/false and scenario stem-based multiple-choice questions and 25 attitudinal questions scored on a Likert scale. Demographic questions included first language, ethnicity and personal consumption of alcohol and tobacco. Findings The competence (knowledge plus skills) correct scores increased from 23.4% at the second year to 53.6% at the fourth year to 71.8% at the sixth year, being better in those students who drank alcohol and whose first language was English (P < 0.002). As training progressed the student's perceptions of their role adequacy regarding the effectiveness of the management of illicit drug users diminished. For example, at second year 21% and at sixth year 51% of students felt least effective in helping patients to reduce illicit drug use. At the sixth year, 15% of sixthyear students regarded the self-prescription of psychoactive drugs as responsible practice. Conclusion Education on alcohol and drugs for students remains a crucial but underprovided part of the undergraduate medical curriculum. This research demonstrated that while positive teaching outcomes were apparent, further changes to medical student curricula need to be considered to address specific knowledge deficits and to increase the therapeutic commitment and professional safety of medical students to alcohol and drugs. [source] The use of the OSCE in postgraduate educationEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2008R. C. Arnold Abstract Background:, The Objective Structured Clinical Examination (OSCE) is a method of assessing the clinical skills of undergraduates in medicine, dentistry and other health sciences and is employed increasingly in postgraduate education. Aim:, To describe the application of the OSCE to the development of Lifelong Learning and Continuing Professional Development (CPD) for General Dental Practitioners (GDPs). Methods:, A postgraduate course was designed as an OSCE for GDPs. The OSCE comprised 12 stations covering different aspects of general dentistry. After an introductory seminar outlining the aim of the course, the participants spent 7 min at each station. Each question or task required 10 answers and was designed to highlight areas of weakness or interest and to stimulate further study of the presenting topic. Solutions and answers were provided at each station for self-assessment along with a list of locally presented courses related to that subject. Participants were invited to leave contact details and to make suggestions for future postgraduate courses. The final session consisted of a group discussion and participants were invited to complete an evaluation form to express opinions on the course. Results:, The evaluation demonstrated that most candidates found participation in the OSCE stimulated their interest in CPD. The OSCE also highlighted areas of weakness in knowledge of certain clinical procedures. Group discussion confirmed that practitioners found the hands-on component valuable and that they were likely to participate in further OSCEs to enhance their CPD. Suggestions received during the discussion were used to modify the course. Conclusions:, The OSCE course fulfilled its aim of assisting practitioners to organise their CPD. The reflective nature of the course was helpful in evaluating clinical knowledge and the unique multidisciplinary style fulfilled its objective in promoting thoughts regarding future study. [source] Measuring the value and impact of health library and information services: past reflections, future possibilitiesHEALTH INFORMATION & LIBRARIES JOURNAL, Issue 2007Joanne Gard Marshall Objectives:, To summarize the context, history and results of research studies conducted on the value and impact of health library and information services by the author since 1975 and to use this as a basis for examining ongoing developments related to evaluation research. To provide a comprehensive bibliography of library value and impact studies. Methods:, Literature review and background based on personal involvement in the studies under discussion. Results:, The author's studies demonstrate an ongoing evolution of value and impact studies since the mid-1970s. In health sciences libraries, the approach taken to measuring value and impact has been strongly influenced by the type of research being conducted in the health sciences field as a whole. As a result, health sciences library researchers have become early adopters of methods that incorporate outcome and impact measures and rigorous research designs, and the concept of evidence-based library and information practice. The paper recommends that a range of research approaches from various disciplines be used to guide future evaluation research. Conclusions:, Value and impact studies will continue to be important resources for evidence-based practice as health information professionals deal with evolving user needs and new ways of delivering information to a variety of audiences.

A new way of thinking about research in librarianship is introduced using the well-built question process and the assignment of librarian research questions to one of six domains specific to librarianship. As a profession, librarianship tends to reflect more qualitative, social sciences/humanities in its research methods and study types which tend to be less rigorous and more prone to bias. Randomised controlled trials (RCT) do not have to be placed at the top of an evidence ,hierarchy' for librarianship. Instead, a more encompassing model reflecting librarianship as a whole and the kind of research likely to be done by librarians is proposed. ,Evidence' from a number of disciplines including health sciences, business and education can be utilized by librarians and applied to their practice. However, access to and availability of librarianship literature needs to be further studied. While using other disciplines (e.g. EBHC) as a model for EBL has been explored in the literature, the authors develop models unique to librarianship. While research has always been a minor focus in the profession, moving research into practice is becoming more important and librarians need to consider the issues surrounding research in order to move EBL forward. [source] Smoothing Observational Data: A Philosophy and Implementation for the Health SciencesINTERNATIONAL STATISTICAL REVIEW, Issue 1 2006Sander Greenland Summary Standard statistical methods (such as regression analysis) presume the data are generated by an identifiable random process, and attempt to model that process in a parsimonious fashion. In contrast, observational data in the health sciences are generated by complex, nonidentified, and largely nonrandom mechanisms, and are analyzed to form inferences on latent structures. Despite this gap between the methods and reality, most observational data analysis comprises application of standard methods, followed by narrative discussion of the problems of entailed by doing so. Alternative approaches employ latent-structure models that include components for nonidentified mechanisms. Standard methods can still be useful, however, provided their modeling philosophy is modified to encourage preservation of structure, rather than achieving parsimonious description. With this modification they can be viewed as smoothing or filtering methods for separating noise from signal before the task of latent-structure modeling begins. I here give a detailed justification of this view, and a hierarchical-modeling implementation that can be carried out with popular software. Concepts are illustrated in the smoothing of a contingency table from an analysis of magnetic fields and childhood leukemia. Résumé Les méthodes statistiques standard (telles que l'analyse par régression) supposent que les données sont générées par un processus aléatoire identifiable, et tentent de modéliser ce processus d'une façon parcimonieuse. Par contraste, les données d'observation dans les sciences de la santé sont générées par des mécanismes complexes, non identifiés et largement non aléatoires, et elles sont analysées pour tirer des conclusions sur les structures latentes. En dépit de cet écart entre les méthodes et la réalité, l'analyse de la plupart des données d'observation comprend l'application des méthodes standard, suivies par la discussion narrative des problèmes engendrés par ces procédés. Les approches alternatives emploient des modèles à structure latente qui incluent des composantes pour les mécanismes non identifiés. Cependant, les méthodes standard peuvent encor être utiles, à condition que la conception de leur modélisation soit modifiée pour encourager la préservation de la structure, plutôt que d'arriver à une description parcimonieuse. Avec cette modification elles peuvent être considérées comme des méthodes de lissage ou de filtrage pour séparer le bruit du signal avant que commence le travail de modélisation à structure latente. Je donne ici une justification detaillée de cette opinion et je présente une mise en oeuvre de modélisation hiérachique qui peut être réalisée avec un logiciel courant. Les concepts sont illustrés dans le lissage d'un tableau de contingence à partir d'une analyse de champs magnétiques et de leucémie enfantine. [source] Nursing Education at an Art GalleryJOURNAL OF NURSING SCHOLARSHIP, Issue 2 2000Britt-Maj Wikström Purpose: To introduce an experiential teaching-learning method in nursing education based on art gallery visits. Works of art communicate a broad spectrum of human experiences and thoughts, and can be useful when studying interpersonal relations. Design: Theoretical framework on experiential learning was based on writings of Dewey and Burnard. Data were collected from nursing students (N = 206) at a university college of health sciences in Sweden during a 3-year period, 1995,1998. Method: The pedagogical approach was experiential and based on three phases: observation, conceptualisation, and reflection. When students visited the art gallery, they were encouraged to look for metaphoric expressions of interpersonal relations. Students were asked to interpret the art, report findings to fellow-students, and evaluate the program. Findings: Studying works of art was a powerful teaching-learning method for understanding interpersonal relations. Students related interpretations of a work of art to interpersonal relations in nursing. Conclusions: Nursing students' observations and understanding of interpersonal relations were enhanced by the art gallery program. [source] Estimating the variance of estimated trends in proportions when there is no unique subject identifierJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 1 2007William K. Mountford Summary., Longitudinal population-based surveys are widely used in the health sciences to study patterns of change over time. In many of these data sets unique patient identifiers are not publicly available, making it impossible to link the repeated measures from the same individual directly. This poses a statistical challenge for making inferences about time trends because repeated measures from the same individual are likely to be positively correlated, i.e., although the time trend that is estimated under the naïve assumption of independence is unbiased, an unbiased estimate of the variance cannot be obtained without knowledge of the subject identifiers linking repeated measures over time. We propose a simple method for obtaining a conservative estimate of variability for making inferences about trends in proportions over time, ensuring that the type I error is no greater than the specified level. The method proposed is illustrated by using longitudinal data on diabetes hospitalization proportions in South Carolina. [source] Race, Ethnicity, and Racism in Medical Anthropology, 1977,2002MEDICAL ANTHROPOLOGY QUARTERLY, Issue 1 2008Clarence C. Gravlee Researchers across the health sciences are engaged in a vigorous debate over the role that the concepts of "race" and "ethnicity" play in health research and clinical practice. Here we contribute to that debate by examining how the concepts of race, ethnicity, and racism are used in medical,anthropological research. We present a content analysis of Medical Anthropology and Medical Anthropology Quarterly, based on a systematic random sample of empirical research articles (n =283) published in these journals from 1977 to 2002. We identify both differences and similarities in the use of race, ethnicity, and racism concepts in medical anthropology and neighboring disciplines, and we offer recommendations for ways that medical anthropologists can contribute to the broader debate over racial and ethnic inequalities in health. [source] Reconciling pedagogy and health sciences to promote Indigenous healthAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2000Denise Main Objectives: To increase knowledge and skills regarding Indigenous learning styles. To raise awareness within the tertiary education sector that Aboriginal students learn differently and that Indigenous cultures and pedagogy have validity and strength. To examine pedagogical strategies that assist both tertiary students capacity for learning and university lecturers' delivery and evaluation of teaching and learning strategies. Methods: A qualitative, ethnographic framework using personal observations, field and classroom experience, interviews and review of literature in the fields of education, public health and Indigenous cultural perspectives. Results: Aboriginal people are the receivers of services and programs that will be delivered, in the majority of cases, by university-educated, non-Aboriginal, professional health care providers. Indigenous students face specific challenges in obtaining an effective education for working in the Aboriginal and wider community in the field of public health; the challenges relate to culture, health paradigms and community. Conclusion: Lecturers in health and human science courses for Aboriginal students need to both examine and appreciate the cultural constraints on learning faced by their students within the context of mainstream curriculum, and to build on the large pool of knowledge and learning styles that Aboriginal society bequeaths to Aboriginal students. Implications: Academics can apply the cultural differences and knowledge base of the Indigenous community as a force to promote health through learning. [source] | |||||||||||||||||||
