    Making the case for an obstetric medicine subspecialty in South Africa
    (Health & Medical Publishing Group, 2020-11) Zamparini, J; Wium, L
    Obstetric medicine is a subspecialty of internal medicine that involves the management of medical conditions that may affect the course of pregnancy. It is an established subspecialty in many parts of the world, with recognised training programmes and an active international society; however, no formal training programme has been developed in South Africa (SA) as yet. Medical problems are responsible for the majority (60%) of maternal deaths in SA and women of childbearing potential are disproportionately affected by medical conditions such as HIV and obesity. Obstetric physicians would play a complementary role in the care of pregnant patients and could contribute to improving maternal health and lowering the maternal mortality rate in SA

    Classical Cardiovascular Risk Factors and HIV are Associated With Carotid IntimaMedia Thickness in Adults From SubSaharan Africa Findings From H3Africa AWIGen Study
    (2019-06-07) Boua P; Ali S; Soo C
    Background-—Studies on the determinants of carotid intima-media thickness (CIMT), a marker of sub-clinical atherosclerosis, mostly come from white, Asian, and diasporan black populations. We present CIMT data from sub-Saharan Africa, which is experiencing a rising burden of cardiovascular diseases and infectious diseases. Methods and Results-—The H3 (Human Hereditary and Health) in Africa’s AWI-Gen (African-Wits-INDEPTH partnership for Genomic) study is a cross-sectional study conducted in adults aged 40 to 60 years from Burkina Faso, Kenya, Ghana, and South Africa. Cardiovascular disease risk and ultrasonography of the CIMT of right and left common carotids were measured. Multivariable linear and mixed-effect multilevel regression modeling was applied to determine factors related to CIMT. Data included 8872 adults (50.8% men), mean age of 50 6 years with age- and sex-adjusted mean ( SE) CIMT of 640 123lm. Participants from Ghana and Burkina Faso had higher CIMT compared with other sites. Age (b = 6.77, 95%CI [6.34–7.19]), body mass index (17.6[12.5–22.8]), systolic blood pressure (7.52[6.21–8.83]), low-density lipoprotein cholesterol (5.08[2.10–8.06]) and men (10.3[4.75– 15.9]) were associated with higher CIMT. Smoking was associated with higher CIMT in men. High-density lipoprotein cholesterol (12.2 [17.9– 6.41]), alcohol consumption (–13.5 [19.1–7.91]) and HIV (8.86 [15.7–2.03]) were inversely associated with CIMT. Conclusions-—Given the rising prevalence of cardiovascular diseases risk factors in sub-Saharan Africa, atherosclerotic diseases may become a major pan-African epidemic unless preventive measures are taken particularly for prevention of hypertension, obesity, and smoking. HIV-specific studies are needed to fully understand the association between HIV and CIMT in sub-Saharan Africa

    HIV-related knowledge, perceptions, attitudes, and utilisation of HIV counselling and testing: a venue-based intercept commuter population survey in the inner city of Johannesburg, South Africa
    (2015) Chimoyi, L; Tshuma, N; Muloongo, K
    Background: HIV counselling and testing (HCT) and knowledge about HIV have been key strategies utilised in the prevention and control of HIV/AIDS worldwide. HIV knowledge and uptake of HCT services in sub-Saharan Africa are still low. This study was conducted to determine factors associated with HCT and HIV/AIDS knowledge levels among a commuter population in Johannesburg, South Africa. Objective: To identify the factors associated with HCT uptake among the commuter population. Design: A simple random sampling method was used to select participants in a venue-based intercept survey at a taxi rank in the Johannesburg Central Business District. Data were collected using an electronic questionnaire. Logistic regression analysis assessed factors associated with HIV testing stratified by gender. Results: 1,146 respondents were interviewed, the ma[j]ority (n = 579, 50.5%) were females and (n = 780, 68.1%) were over 25 years of age. Overall HCT knowledge was high (n = 951, 83%) with more females utilising HCT facilities. There was a significant difference in HIV testing for respondents living closer to and further away from health facilities. Slightly more than half of the respondents indicated stigma as one of the barriers for testing (n = 594, 52%, p-value = 0.001). For males, living with a partner (aOR: 1.68, 95% CI: 1.02-2.78, p-value: 0.041) and possessing a post-primary education were positively associated with testing (aOR: 2.00, 95% CI: 1.15-3.47, p-value: 0.014), whereas stigma and discrimination reduced the likelihood of testing (aOR: 0.40, 95% CI: 0.31-0.62, p-value: <0.001). For females, having one sexual partner (aOR: 2.65, 95% CI: 1.19-5.90, p-value: 0.017) and a low perceived benefit for HIV testing (aOR: 0.54, 95% CI: 0.30-0.96, p-value: 0.035) were associated with HIV testing. Conclusion: The overall HIV/AIDS knowledge was generally high. Gender-specific health education and HIV intervention programmes are needed for improved access to HCT services. One favourable intervention would be the use of home-based HCT programmes.

    Should HIV be a notifiable disease? Old questions with some new arguments
    (2014-09) Venter, W D F; Black, A; Allais, L; et al
    HIV notification enters national debate regularly, often introduced by politicians and supported by many individual healthcare workers. We argue that its proponents advance confused or poorly informed rationales for making HIV notifiable. We present reasons why making HIV notifiable would be inappropriate in South Africa, why the public health benefits of a notification programme are not even likely, and why there are risks of public health and human rights harms.

    Elimination of mother- to - child transmission of HIV in South Africa : Rapid scale- up using quality improvement
    (2014-03) Bardwaj, S.; Barron, P.; Treger-Slavin, P.; et al
    Background: South Africa (SA) is committed to achieving the goal of eliminating mother-to-child transmission (MTCT) of HIV by 2015. To achieve this, universal coverage of quality antenatal, labour, delivery and postnatal services for all women has to be attained. Over the past decade, the prevention of mother-to-child transmission (PMTCT) programme has been scaled up to reach all healthcare facilities in the country. However, challenges persist in achieving 100% coverage and access to the programme. Objectives: We describe the process undertaken by the National Department of Health (NDoH), in collaboration with partners, to develop, implement and monitor a data-driven intervention to improve facility, district, provincial and national PMTCT-related performance. Methods: Between 2011 and 2013, the NDoH developed and implemented an intervention using data-driven participatory processes to understand facility-level bottlenecks to optimise PMTCT implementation and to scale up priority PMTCT actions nationally. Results: There was remarkable improvement across all key indicators in the PMTCT cascade over the 3 years 2011 - 2013. Simple monitoring tools such as a visual dashboard and data for action reports were successfully used to improve the performance of the PMTCT programme across SA. MTCT has shown a significant downward trend. Conclusions: It is feasible to implement district-level, data-driven quality improvement processes at a national scale to improve the performance of the PMTCT programme at the local level.

    Focus on adolescents with HIV and AIDS
    (2014-12) Fairlie, L; Sipambo, N; Fick, C; et al
    Adolescents living with HIV, including those infected perinatally and non-perinatally, bear a disproportionate burden of the HIV epidemic in South Africa. This article discusses HIV management in adolescents including the following aspects: (i) burden of HIV disease, modes of HIV acquisition and implications for management; (ii) initiation of combination antiretroviral therapy (ART), outcomes and complications of ART in adolescents,including virological failure and switching regimens; (iii) adherence in adolescence, including factors that may contribute to poor adherence and advice to improve adherence; (iv) issues particular to adolescents, including sexual and reproductive health needs, disclosure to adolescents and by adolescents, and transition to adult care. This article aims to provide insights based on the literature and experience to assist the clinician to navigate the difficulties of managing HIV in adolescence and achieving successful transition to adult care.
