Pandemic and bills: The impact of COVID-19 on energy usage of schools in South Africa.

The COVID-19 pandemic continues to wreak havoc on global operations and economies. Inadvertently, lock-downs and working from home have reduced the daily carbon footprints of inter alia transport and office buildings. A beneficial consequence of carbon footprint reductions is the ability to measure the differential demand of occupants, to benchmark the base load of buildings, and identify opportunities for efficiency improvements. In this paper we evaluate the change in energy demand in five public schools in South Africa with changes in occupancy due to the COVID-19-imposed lockdowns. We make recommendations to carry these savings into the everyday operation of the schools, and estimate the savings for forthcoming closures.

Haematopoietic stem cell transplantation in South Africa: Current limitations and future perspectives.

The growing need for haematopoietic stem cell transplantation (HSCT) is reflected in the increasing number of transplants performed globally each year. HSCT provides life-changing and potentially curative therapy for a range of pathologies including haematological malignancies; other indications include certain congenital and acquired disorders of the haematopoietic system, autoimmune conditions and hereditary diseases. The primary goals of HSCT are either to replace haematopoietic stem and progenitor cells (HSPC) following myeloablative chemotherapy or to cure the original pathology with allogeneic HSPCs. Success depends on optimal outcomes at various stages of the procedure including mobilisation of marrow stem/progenitor cells for harvesting from the patient or donor, long-term and sustainable engraftment of these cells in the recipient, and prevention of graft-versus-host disease in the case of allogeneic HSCT. Challenges in South Africa include high cost, limited infrastructure and lack of appropriately trained staff, as well as limitations in securing suitable haematopoietic stem cell donors. This review aims to provide an overview of HSCT and some of the challenges that are faced in the South African context.
