Does medical student willingness to practise peer physical examination translate into action?

Background: Peer physical examination (PPE) is commonly used in clinical skills teaching to allow students to practice physical examination techniques on each other. Previous studies have demonstrated medical students' generally positive attitudes towards PPE, but the correlation between student attitude and actual practice of PPE has yet to be examined. Aim: To determine if a positive student attitude towards PPE leads to subsequent action. Methods: The target population were MBBS I students (20062007 cohort) admitted to the Li Ka Shing Faculty of Medicine, The University of Hong Kong. Student attitude towards PPE and subsequent practice of PPE were assessed through self-completed written questionnaires before and after the compulsory Clinical Skills Programme (CSP). Results: A total of 100/128 (78%) students completed both questionnaires, of which 83 (65%) could be linked to demographic data. All study participants were ethnically Chinese. A high level of willingness to conduct PPE persisted before and after the CSP for both male and female students. However, more than half of the students did not subsequently examine various non-intimate body regions of a fellow student during the CSP. Female students were more likely to exhibit attitudebehaviour inconsistency. Conclusion: The existing positive attitudes towards PPE need to be harnessed so that more students are encouraged to follow through and actually practise PPE, thus realizing the educational benefits of this activity. This may be done by ensuring that PPE is conducted in a safe setting while being conscientious of gender differences. Scheduled time and the use of a logbook may be useful to facilitate students practising PPE. © 2011 Informa UK Ltd All rights reserved.postprin

Personal and psychosocial predictors of doping use in physical activity settings: a meta-analysis.

Background: There is a growing body of empirical evidence on demographic and psychosocial predictors of doping intentions and behaviors utilizing a variety of variables and conceptual models. However, to date there has been no attempt to quantitatively synthesize the available evidence and identify the strongest predictors of doping. Objectives: Using meta-analysis, we aimed to (i) determine effect sizes of psychological (e.g. attitudes) and social-contextual factors (e.g. social norms), and demographic (e.g. sex and age) variables on doping intentions and use; (ii) examine variables that moderate such effect sizes; and (iii) test a path analysis model, using the meta-analyzed effect sizes, based on variables from the theory of planned behavior (TPB). Data Sources: Articles were identified from online databases, by contacting experts in the field, and searching the World Anti-Doping Agency website. Study Eligibility Criteria and Participants: Studies that measured doping behaviors and/or doping intentions, and at least one other demographic, psychological, or social-contextual variable were included. We identified 63 independent datasets. Study Appraisal and Synthesis Method: Study information was extracted by using predefined data fields and taking into account study quality indicators. A random effects meta-analysis was carried out, correcting for sampling and measurement error, and identifying moderator variables. Path analysis was conducted on a subset of studies that utilized the TPB. Results: Use of legal supplements, perceived social norms, and positive attitudes towards doping were the strongest positive correlates of doping intentions and behaviors. In contrast, morality and self-efficacy to refrain from doping had the strongest negative association with doping intentions and behaviors. Furthermore, path analysis suggested that attitudes, perceived norms, and self-efficacy to refrain from doping predicted intentions to dope and, indirectly, doping behaviors. Limitations: Various meta-analyzed effect sizes were based on a small number of studies, which were correlational in nature. This is a limitation of the extant literature. Conclusions: This review identifies a number of important correlates of doping intention and behavior, many of which were measured via self-reports and were drawn from an extended TPB framework. Future research might benefit from embracing other conceptual models of doping behavior and adopting experimental methodologies that will test some of the identified correlates in an effort to develop targeted anti-doping policies and programs

Deletions within the azoospermia factor subregions of the Y chromosome in Hong Kong Chinese men with severe male-factor infertility: controlled clinical study.

OBJECTIVE: To determine the patterns and the prevalence of microdeletions in the azoospermia factor subregions of the Y chromosome in Hong Kong Chinese men with severe male-factor infertility. DESIGN: Controlled clinical study. SETTING: Reproductive centre of a university teaching hospital, Hong Kong. PARTICIPANTS: Fifty-eight men with severe male-factor infertility who participated in the in vitro fertilisation programme from May 1998 through March 1999, and 46 male volunteers with proven fertility. MAIN OUTCOME MEASURES: Polymerase chain reaction analysis of DNA from peripheral blood lymphocytes using six loci spanning the AZFa, AZFb, and AZFc subregions of the Y chromosome. RESULTS. No microdeletions were detected in the fertile controls or in patients with obstructive azoospermia. Deletions within the AZFc subregion were found in 9% (4/44) of men with non-obstructive azoospermia or severe oligospermia. Neither AZFa nor AZFb deletions were detected in any participants. CONCLUSION: Deletions within the azoospermia factor subregions of the Y chromosome are associated with severe male-factor infertility in Hong Kong Chinese men.published_or_final_versio

Advantages of video trigger in problem-based learning

Background: Traditionally, paper cases are used as 'triggers' to stimulate learning in problem-based learning (PBL). However, video may be a better medium because it preserves the original language, encourages the active extraction of information, avoids depersonalization of patients and allows direct observation of clinical consultations. In short, it exposes the students to the complexity of actual clinical problems. Aim: The study aims to find out whether students and facilitators who are accustomed to paper cases would prefer video triggers or paper cases and the reasons for their preference. Method: After students and facilitators had completed a video PBL tutorial, their responses were measured by a structured questionnaire using a modified Likert scale. Results: A total of 257 students (92) and 26 facilitators (100) responded. The majority of students and facilitators considered that using video triggers could enhance the students' observational powers and clinical reasoning, help them to integrate different information and better understand the cases and motivate them to learn. They found PBL using video triggers more interesting and preferred it to PBL using paper cases. Conclusion: Video triggers are preferred by both students and facilitators over paper cases in PBL. © 2010 Informa UK Ltd All rights reserved.postprin

Prevalence and awareness of lower urinary tract symptoms among males in the Outpatient Clinics of Universiti Kebangsaan Malaysia Medical Centre.

This study aims to determine the prevalence of lower urinary tract symptoms (LUTS) and level of awareness among male outpatients in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A questionnaire consisting of demographic data, questions related to knowledge, attitude and practice on BPH and the International Prostate Symptom Score (IPSS) was used for this study. Uroflowmetry and bladder scan were used to evaluate the function of the urinary tract and severity of BPH. Urine dipstick was done for glycosuria, proteinuria and haematuria. A total of 220 respondents were surveyed. The prevalence of moderately and severely symptomatic LUTS was 42.7%. The most commonly reported LUTS were nocturia (78.2%), frequency (58.2%) and incomplete emptying (44.6%). The prevalence of glycosuria, proteinuria and haematuria were 23.6%, 11.4% and 1.8% respectively. There was a significant association between increasing age with the severity of LUTS (p=0.005). Out of 102 respondents with voided urine volume greater than 150 mL, there was a significant decrease in maximum (Qmax) (p=0.039) and average (Qave) urine flow rates with every 10 years increase of age (p=0.001). The majority of respondents (59.5%) have heard of BPH before. Over 78.2% of the respondents would seek medical attention if they have LUTS with 15.9% saying they would seek traditional treatment. In conclusion, the prevalence of LUTS was high and the level of awareness was satisfactory
