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.

Monoclonal antibodies or fusion proteins, defined as biological drugs, have modified the natural history of numerous immune-mediated disorders, allowing the development of therapies aimed at blocking the pathophysiological pathways of the disease, providing greater efficacy and safety than conventional treatment strategies. Virtually all therapeutic proteins elicit an immune response, producing anti-drug antibodies (ADAs) against hypervariable regions of immunoglobulins. Immunogenicity against biological drugs can alter their pharmacokinetic and pharmacodynamic properties, thereby reducing the efficacy of these drugs. ⋯ Among the new therapeutic strategies for the management of psoriasis, biological agents have gained increasing importance in recent years as they interrupt key inflammation pathways involved in the physiopathology of the disease. Reports regarding ADA in new biologics are still scarce, but the most recent evidence tends to show little impact on the clinical response to the drug, even with prolonged treatment. It is therefore essential to standardize laboratory tests to determine the presence and titles of ADAs to establish their administration and management guidelines that allow the determination of the real clinical impact of these drugs.

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.

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.

Observational StudyAcute Morbidity and Mortality Analysis of COVID-19 in Children Receiving Cancer Treatment.
The aim of this study was to determine overall morbidity and mortality of COVID-19 infection in children on cancer treatment. It was an observational study, carried at Shaukat Khanum Cancer Hospital from 1st April 2020 to 31st July 2020. A total of 165 children on active cancer treatment were tested for COVID-19 with PCR; out of these, 17 were detected positive. ⋯ Chemotherapy was modified in five children, while elective surgery, chemotherapy and radiotherapy schedule were affected in eight children. Overall, the spread of Covid-19 was limited, the course of disease was mild, and anticancer treatment was provided and continued as per standard protocols.
