Whether COVID-19 patients in need of extended care in an intensive care unit qualify for 'emergency medical treatment' is answered by considering the Constitution, the meaning of emergency medical treatment, and whether such patients are in an incurable chronic condition. Considering ethical guidelines for the withholding and withdrawal of treatment may assist a court in determining whether a healthcare practitioner has acted with the degree of skill and care required of a reasonably competent practitioner in his or her branch of the profession.

Emerging evidence reveals a strong association between COVID-19 and obesity in terms of disease severity, need for hospitalisation and risk of mortality. In this review, we discuss cellular and molecular mechanisms potentially contributing to the pathophysiology of COVID-19 in obese patients. Understanding the relationship between COVID-19 and obesity is pertinent for the clinical management of these patients.

Comparative Study
Dose-related treatment outcomes in South African patients prescribed clofazimine for drug-resistant tuberculosis.
Optimal drug levels and minimal toxicity are critical factors in improving treatment outcomes for patients' prescribed new and repurposed medicine for drug-resistant (DR) tuberculosis (TB). The optimal dose of clofazimine (CFZ), a repurposed medicine for DR-TB, that is safe and effective in the South African (SA) population is unknown. ⋯ Dose-weight interaction plays a role in the odds of a successful outcome. There is an association between dose-weight interactions, outcomes and adverse events. Weight-based dosing in patients <50 kg and ≥50 kg must be considered to achieve optimal treatment outcomes and reduce adverse events. Active drug safety monitoring must be implemented as a package of care for patients receiving CFZ as part of a DR-TB treatment regimen.
