Randomized Controlled Trial Comparative Study
Comparison of ultraviolet C light and isopropyl alcohol for the disinfection of cellular phones in a paediatric intensive care unit setting.
A considerable proportion of cellular phones (cell phones) used by healthcare workers (HCWs) have been shown to be contaminated with pathogenic micro-organisms, making these devices reservoirs to infect susceptible patients. Although many units have well-defined infection control protocols, methods for the decontamination of cell phones are scarce. ⋯ Although both 70% isopropyl alcohol and UVC light disinfection effectively reduced CFUs following decontamination, 70% isopropyl alcohol was determined to be much more effective.

Randomized Controlled Trial Comparative Study
A randomised trial comparing preoperative administration of single-dose kefazolin to kefazolin plus metronidazole as prophylactic antibiotics at caesarean section.
Caesarean section is a life-saving procedure which is associated with high rates of maternal and neonatal complications. It has been estimated that globally, 29.7 million births occur by caesarean section annually. The risk of postpartum infection is estimated to be five to ten times higher compared with normal vaginal delivery. Pregnancy-related sepsis was listed as a top-six cause of maternal mortality in the South African Saving Mothers report between 2017 and 2019. Multiple trials have been conducted in an attempt to optimise administration of prophylactic antibiotics in an effort to reduce postpartum infection and maternal sepsis, and current practice guidelines suggest that there is sufficient evidence that extended-spectrum antibiotics, in combination with kefazolin, result in reduction of postpartum infections. ⋯ The overall sepsis rate in this study was 5.64%. Postpartum infection is multifactorial and there are multiple factors that can be addressed in strengthening the sepsis care bundle. We do not recommend the addition of metronidazole to kefazolin as prophylaxis at caesarean section.

To investigate the effect of perioperative administration of kefazolin alone compared to kefazolin plus metronidazole on postpartum infection in women undergoing caesarean section at Kalafong Provincial Tertiary Hospital. ⋯ The overall sepsis rate in this study was 5.64%. Postpartum infection is multifactorial and there are multiple factors that can be addressed in strengthening the sepsis care bundle. We do not recommend the addition of metronidazole to kefazolin as prophylaxis at caesarean section.

Randomized Controlled Trial
Impact of COVID-19 primary healthcare service restrictions on patients with chronic obstructive pulmonary disease in Cape Town, South Africa.
Patients with chronic obstructive pulmonary disease (COPD) typically experience multidimensional symptoms throughout the course of their disease, with burdensome physical symptoms, social isolation, and additional psychological suffering. COVID-19 lockdown resulted in restrictions on chronic care delivery at primary healthcare (PHC) facilities, and it is not known what the care experiences of patients with COPD were during this time. ⋯ The COVID-19 lockdown PHC service restrictions caused a disruption to the continuity of care for patients with COPD, with associated worry, anxiety and disappointment. Medication access was largely supported by the home delivery of chronic medication. We suggest that there are opportunities for providing more sustained support for patients with COPD through referrals to community health workers, and also through telephonic patient follow-up by primary care teams.

Randomized Controlled Trial
Safety and efficacy of inclisiran in South African patients at high cardiovascular risk: A subanalysis of the ORION phase III clinical trials.
Inclisiran significantly reduced low-density lipoprotein cholesterol (LDL-C) in individuals with heterozygous familial hypercholesterolaemia, established atherosclerotic cardiovascular disease (ASCVD) or ASCVD risk equivalents (type 2 diabetes, familial hypercholesterolaemia or a 10-year risk of a cardiovascular event ≥20%) in the ORION phase III clinical trials. Infrequent dosing at days 1, 90, 270 and 450 resulted in a mean LDL-C reduction of ~50%. A total of 298 participants from South Africa (SA) were enrolled. ⋯ The corresponding time-averaged reduction in LDL-C was 52.8% (95% CI -57.9 - -47.8; p<0.0001). Treatment-emergent adverse events at the injection site were more common with inclisiran compared with placebo (10.1% v. 0.7%); however, all were mild or moderate in nature and none were persistent. Conclusion. Inclisiran, given in addition to maximally tolerated standard lipid-lowering therapy, is effective and safe and results in robust reductions in LDL-C in SA patients at high cardiovascular risk.
