RESUMO
BACKGROUND: The majority of maternal deaths in South Africa (SA) occur as a result of non-pregnancy-related infections (NPRI). Pregnancy is a known risk factor in severe COVID19, increasing the burden of NPRI in SA. In this study, we describe the prevalence, profile and clinical outcomes of pregnant women with COVID19 admitted to a tertiary facility. OBJECTIVES: To describe the prevalence, profile and clinical outcomes of pregnant women with COVID19 admitted to a tertiary facility in Gauteng, SA. METHODS: We performed a retrospective review of all pregnant women with COVID19 admitted to Charlotte Maxeke Johannesburg Academic Hospital between 6 March and 30 August 2020. Data collected included demographics, medical history, obstetric history, clinical findings and laboratory variables. Outcomes assessed were mortality, admission to intensive care unit (ICU), symptomatic v. asymptomatic disease, maternal and fetal outcome and mode of delivery. RESULTS: A total of 204 pregnant women were included in the study. Of these, 33 (16.2%) women were critically ill, with 21 (10.3%) admitted to the ICU and 3 (1.5%) deaths related to COVID19. The median gestational age was 37 weeks and median birthweight 2 940 g. Sixty-seven women (33%) were HIV-positive, in keeping with national statistics regarding HIV in pregnancy. Caesarean section was the most common mode of delivery (n=105, 60%). However, no women underwent caesarean section for indications related to COVID19. CONCLUSION: COVID19-related mortality in our cohort was higher than that seen internationally, likely due to differences in background maternal mortality rates and difficulty in accessing care.

Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations, establishing the potential for the evolution of isolation by distance. Here, we assess the pattern of differentiation among six breeding colonies of the southern elephant seal, Mirounga leonina, based on mtDNA and 15 neutral microsatellite DNA markers, and consider measures of their demography and connectivity. We show that all breeding colonies are genetically divergent and that connectivity in this highly mobile pinniped is not strongly associated with geographic distance, but more likely linked to Holocene climate change and demographic processes. Estimates of divergence times between populations were all after the last glacial maximum, and there was evidence for directional migration in a clockwise pattern (with the prevailing current) around the Antarctic. We discuss the mechanisms by which climate change may have contributed to the contemporary genetic structure of southern elephant seal populations and the broader implications.

The primary purpose of an improved water supply and sanitation is the achievement of acceptable health and hygiene standards as well as the sustainable improvement of the environment. Many governments recognize this and so they budget for large sums of money to improve these services to the communities. The purpose of this study was to investigate the different gaps in environmental health and hygiene practices with the aim of suggesting a strategy of improving this in the Northern Province of South Africa. To do this, 231 households and 30 schools were surveyed. Workshops and visits to different government departments were also used. This paper reports the results from this study which indicate that the situation in schools was not any better than that in households, with more than 90% of the villages still dependent on the unimproved pit latrines and 56,6% relying on standpipes which were (70% of the time) non-operational. The main problems identified seem to those associated with implementation and maintenance. The study concludes that with proper training of the water committees and their active involvement with the government and NGOs, environmental health and hygiene problems can be minimized or eliminated.
