Suicidal thoughts and behaviours in Cape Town
Suicidal thoughts and behaviours (STBs) are traditionally attributed to mental disorders; however, increasing evidence indicates that social determinants contribute to suicide risk. We examined STBs and their socioeconomic, psychosocial and clinical correlates in two communities in Cape Town. We conducted psychiatric diagnostic interviews (MINI) at three public-sector facilities (2023-2024). Adults aged ≥18 years, with and without HIV, were recru…
Routine Electronic Mother-Infant Data (ReminD)
Data to Care (D2C) strategies- using routine data to identify and re-engage people living with HIV who are not in care- have shown promise in high-income settings but remain underexplored in lower-resource and vertical HIV transmission prevention (VTP) contexts. In this prospective, single-arm, proof-of-concept study, we used facility-linked public sector electronic medical records (Provincial Health Data Centre [PHDC] data) to identify, validate…
Sars-CoV-2 seroepidemiology in Cape Town, South Africa, and implications for future outbreaks in low-income communities
In low- and middle-income countries where SARS-CoV-2 testing is limited, seroprevalence studies can help describe and characterise the extent of the pandemic, as well as elucidate protection conferred by prior exposure. We conducted repeated cross-sectional serosurveys (July 2020 –November 2021) using residual samples from patients from Cape Town, South Africa, sent for routine laboratory studies for non-COVID-19 conditions. SARS-CoV-2 anti-nucle…
Creating a data collection and management platform to support measurement of adolescent HIV care transition processes within low- and middle-income countries
Few national programs and research cohorts within low- and middle-income countries (LMICs) document transition-related processes and outcomes for adolescents and young adults living with HIV (AYLH) transitioning to adulthood. Between 2017–2020, The Global fRAmework of Data collection Used for Adolescent HIV Transition Evaluation (GRADUATE) project convened a collaborative advisory group to identify key variables and definitions capturing the proc…
A prospective randomised controlled trial investigating household Sars-CoV-2 transmission in a densely populated community in Cape Town, South Africa – the transmission of Covid-19 in crowded environm…
Participants had significant exposure to SARS-CoV-2 infections prior to the study. In this setting, household transmission mitigation was ineffective. However, CHWs may have facilitated other important healthcare and social referrals
Authorship inequalities in global health research
BACKGROUND: The International epidemiology Databases to Evaluate AIDS conducts research in several regions, including in Southern Africa. We assessed authorship inequalities for the Southern African region, which is led by South African and Swiss investigators. METHODS: We analysed authorships of publications from 2007 to 2020 by gender, country income group, time and citation impact. We used 2020 World Bank categories to define income groups and…
The association of Sars-CoV-2 infection and tuberculosis disease with unfavorable treatment outcomes
Background Whether SARS-CoV-2 infection and its management influence tuberculosis (TB) treatment outcomes is uncertain. We synthesized evidence on the association of SARS-CoV-2 coinfection ( Coinfection Review ) and its management ( Clinical Management Review ) on treatment outcomes among people with tuberculosis (TB) disease. Methods We systematically searched the literature from 1 January 2020 to 6 February 2022. Primary outcomes included: unfa…
Mental Health, ART Adherence, and Viral Suppression Among Adolescents and Adults Living with HIV in South Africa
We followed adolescents and adults living with HIV aged older than 15 years who enrolled in a South African private-sector HIV programme to examine adherence and viral non-suppression (viral load > 400 copies/mL) of participants with (20,743, 38%) and without (33,635, 62%) mental health diagnoses. Mental health diagnoses were associated with unfavourable adherence patterns. The risk of viral non-suppression was higher among patients with organic …
Evaluation of a public Covid-19 dashboard in the Western Cape, South Africa
The study demonstrated that both the availability of data and an understanding of end-user need is critical when developing and delivering public health tools that may ultimately garner public trust and influence individual behaviour
Growth patterns of infants with in- utero HIV and ARV exposure in Cape Town, South Africa and Lusaka, Zambia
Infant growth trajectories differed by country, highlighting the importance of studying contextual influences on outcomes of infants who were HEU
Diagnosis and treatment of opioid-related disorders in a South African private sector medical insurance scheme
Opportunities during Covid-19 towards achieving Universal Health Coverage
Distribution of advanced HIV disease from three high HIV prevalence settings in Sub-Saharan Africa
In our study, about 1 in 10 PLHIV had advanced HIV with nearly 40% of them unaware of their HIV status. However, a substantial proportion of patients with advanced HIV were established on ART. Our findings suggest the need for a dual focus on alternative testing strategies to identify PLHIV earlier as well as improving ART retention
Prospects for HIV control in South Africa
BACKGROUND: The goal of virtual elimination of horizontal and mother-to-child HIV transmission in South Africa (SA) has been proposed, but there have been few systematic investigations of which interventions are likely to be most critical to reducing HIV incidence. OBJECTIVE: This study aims to evaluate SA's potential to achieve virtual elimination targets and to identify which interventions will be most critical to achieving HIV incidence reduct…
