Observational StudyRisk of SARS-CoV-2 Transmission Among Coworkers in a Surgical Environment.
Health care workers are at high risk for contracting coronavirus disease 2019. However, little is known about the risk of transmission between coworkers. The objective of this study was to determine the risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between coworkers in a surgical environment. ⋯ No new positive cases were found on repeated testing of 387 participants 1 week later. The risk of transmission of SARS-CoV-2 in a health care unit with universal masking and appropriate hand hygiene is low. This finding should provide some reassurance to surgical practices as they reopen.

Online Medical Education and Examinations during COVID-19: Perspectives of a Teaching Associate.
The novel coronavirus disease 2019 (COVID-19) pandemic has not only challenged global health systems but also social, economic, and educational systems. In this short communication, our focus is on its impact on medical education in Pakistan. ⋯ We describe our role as teaching associates (TAs) at the Aga Khan University (AKU); and how it has enabled us to be a part of the transition to online medical education, with a specific focus on online examinations in medical schools. Key Words: Medical education, Online examinations, COVID-19, Pandemic.

The folate pathway is involved in hepatic carcinogenesis and angiogenesis. Polymorphisms in genes related to such processes, including methylene tetrahydrofolate reductase (MTHFR) and vascular endothelial growth factor (VEGF)] may play an important role in the development of hepatocellular carcinoma (HCC). The objective of this study was to evaluate MTHFR and VEGF polymorphisms in Brazilian patients with hepatitis C virus (HCV)-related HCC. ⋯ Our results suggest that these polymorphisms may increase the risk of rapid tumor progression in patients with HCV infection. This subgroup of patients with HCC and who present polymorphism is more likely to be diagnosed with multinodular disease and not be amenable to receiving curative treatments. These data must be validated in larger cohorts, and the screening intervals can be customized based on genetic history.

Dietary modifications and patient-tailored medical management are significant in controlling renal stone disease. Nevertheless, the literature regarding effectiveness is sparse. ⋯ Dietary modifications and medical management significantly aid in correcting urinary metabolic abnormalities. Consequently, reduced nehprolithiasis-related events and better stone burden control is expected.

We present a case of coronavirus disease 2019 (COVİD-19) re-infection where the time interval between two COVİD-positive episodes is the longest in the literature. A 40-year male patient was admitted to the Emergency Department with complaints of sore throat, cough and diarrhea; and was re-diagnosed as COVİD-19 positive after a virus-free period. He did not have a chronic disease in his anamnesis and used no medication. ⋯ In this case, the time to second COVİD-19 infection was 94 days from the first positive PCR test and 86 days from the complete resolution of symptoms. This is one of the longest COVID-19-free period between two episodes of infection in the literature. Key Words: COVID-19, Recurrence, Re-infection, Recovery.
