Coronavirus disease 2019 (COVID-19), caused by infection with the enveloped RNA betacoronavirus, SARS-CoV-2, led to a global pandemic involving over 7 million deaths. Macrophage inflammatory responses impact COVID-19 severity; however, it is unclear whether macrophages are infected by SARS-CoV-2. We sought to identify mechanisms regulating macrophage expression of ACE2, the primary receptor for SARS-CoV-2, and to determine if macrophages are susceptible to productive infection.

Background: Aortopexy is a procedure to reduce pressure on the trachea in children with severe tracheomalacia. Health-related quality of life (HRQoL) has not been studied in children who have undergone aortopexy; we aimed to explore parents' perceptions of their child's HRQoL before and after aortopexy.

Methods: Parents of children < 18 years who underwent aortopexy at a quaternary specialist centre were purposively sampled and invited to participate in a semi-structured interview.

Background: Tuberculosis (TB) is a stigmatised disease with intersectional associations with poverty, HIV, transmission risk and mortality. The use of visible TB infection prevention and control (IPC) measures, such as masks or isolation, can contribute to stigma.

Methods: To explore stigma in this condition, we conducted in-depth individual interviews with 18 health workers and 15 patients in the rural Eastern Cape of South Africa using a semi-structured interview guide and narrative approach.
