E. Mangwayana C. Mahachi T. Taderera V. Chikwasha <p><em><strong>Background</strong></em>: Beyond their traditional relevance (blood transfusion and organ transplants), recent data has shown that blood groups have a role to play in endurance during physical activity.<br><em><strong>Objective</strong></em>: To determine the influences of blood groups and muscle fibre types on endurance.<br><em><strong>Design</strong></em>: An experimental design, specifically an ex post facto design with a cohort of healthy male participants.<br><em><strong>Setting</strong></em>: The research was community based.<br><em><strong>Subjects</strong></em>: Avolunteer sample of 50 male participants from the Faculty of Medicine and Health Sciences was studied. Participants were between the ages of 20-25 years with a physical activity level of less than 4000 MET/minutes/week.Participants with a history of cardiovascular diseases, respiratory diseases and/or were taking any pharmaceutical drug were excluded.<br><em><strong>Main Outcome Measures</strong></em>: An association between blood group, muscle fibre type and endurance during exercise in sedentary individuals.<br><em><strong>Results</strong></em>: Mean age was 21.1±1.1 years. The mean height and weight were 173.88±5.80cm and 67.09±8.63kg respectively. Blood group O participants covered significantly more distance 2.45±1.03 km compared to 1.86±0.52 km covered by non-O blood group participants (*p=0.016) and spent more time on the treadmill 22.30±5.75 minutes compared to 18.03±4.01 minutes covered by the Non-O individuals (*p=0.004). There was a statistically significant association between muscle fibre composition and blood group category (*p=0.002). Most blood O participants (73%) had dominant type I muscle fibres.<br><em><strong>Conclusion</strong></em>: There is an association between the blood group and endurance. Sedentary blood group O individuals have better endurance compared to sedentary Non-O individuals. Participants with dominant type I muscles have better endurance. Agreater proportion of blood group O participants had dominant type I muscle fibres.</p> <p>&nbsp;</p> Copyright (c) Anxiety disorders among pre-clinical students during the COVID-19 pandemic in the Copperbelt province of Zambia 2022-05-10T12:42:44+00:00 J. Chirenda L. M. Mazaba M. Madhombiro S. Siziya <p><em><strong>Background</strong></em>: Anxiety is one of the commonest mental health challenges facing medical students. Levels of anxiety have not been estimated among medical students in Zambia.<br><em><strong>Objectives</strong></em>: To estimate the prevalence of anxiety disorders and its associated factors among pre-clinical students during the COVID-19 pandemic in the Copperbelt province of Zambia.<br><em><strong>Materials and Methods</strong></em>: A sample size of 398 students was sampled using a 1 in 2 systematic random sampling technique. The Zung's Self-rating Anxiety Scale (SAS) was used to determine levels of anxiety. Adjusted Odds Ratios (AOR) and their 95% Confidence Interval (CI) are reported.<br><em><strong>Results</strong></em>: Altogether, 18.9% of the students rated their health poor-fair. Students who rated their health good/excellent were 51% (AOR=0.49; 95% CI [0.36, 0.66]) less likely to report anxiety disorders compared to students who reported their health as poor/fair. Students who indicated that they had chronic lung disease were 49% (AOR=1.49; 95% CI [1.10, 2.02]) more likely to report anxiety disorders compared to students who did not report chronic lung disease.<br><em><strong>Conclusion</strong></em>: Arelatively high level of anxiety disorders was observed among pre-clinical students. Chronic lung diseases and self-rated health should be considered in designing intervention to curtail anxiety in the pre-clinical student population.</p> Copyright (c) SARS-CoV-2 infection in medical trainees after bedside exposure at a teaching hospital in Zimbabwe: case report 2022-05-10T12:46:13+00:00 N. Mukapa M. T. Munemo M. Chiwanza L. Katsidzira R. Makunike-Mutasa <p>Corona Virus Disease 2019 (COVID-19) is predominantly a pneumonic illness caused by a novel coronavirus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). It has rapidly become a pandemic and has affected all facets of life with medical education not spared as well. We are presenting a case of a patient admitted with a pneumonia which turned out to be due to SARS-CoV-2 infection and subsequent transmission to exposed medical trainees. The impact of COVID-19 disease on medical education and different proposals on how medical education can proceed in the face of COVID-19 pandemic are discussed.</p> Copyright (c) Developing a post-graduate curriculum in forensic psychiatry in Zimbabwe 2022-05-10T12:48:51+00:00 W.
