Item ‘A difficult conversation’: Community stakeholders’ and key informants’ perceptions of the barriers to talking about sex and HIV with adolescents and young people in KwaZulu-Natal, South Africa(Culture, Health & Sexuality, 2023) Knight, Lucia; Humphries, Hilton; Van der Pol, Natasha; Ncgobo, NkosinathiAdolescence and young adulthood are important periods of transition and therefore for action and intervention to ensure future sexual and reproductive health (SRH). Caregiver-adolescent communication about sex and sexuality is a protective factor for SRH, but there are often barriers to this. Adults’ perspectives are limited within the literature but important as they should lead this process. This paper uses exploratory qualitative data from in-depth interviews with 40 purposively sampled community stake-holders and key informants to explore their insights into the perceived, experienced or expected challenges adults’ experience when having these conversations within a high HIV prevalence, South African context. Findings suggest that respondents recognized the value of communication and were generally willing to try it. However, they identified barriers such as fear, discomfort and limited knowledge and perceived capacity to do so. They show that in high prevalence contexts adults grapple with their own personal risks, behaviors and fears that may affect their ability to have these conversations. This demonstrates the need to equip caregivers with the confidence and ability to communicate about sex and HIV, alongside managing their own complex risks and situations to overcome barriers. It is also necessary to shift the negative framing of adolescents and sex.Item Impact of antenatal antiretroviral drug exposure on the growth of children who are HIV-exposed uninfected: The national South African prevention of mother to child evaluation cohort study(BMC, 2022) Vundli, Ramakolo; Kuhn, Louise; Lombard, CarlBackground: The relationship between in-utero antiretroviral (ARV) drug exposure and child growth needs further study as current data provide mixed messages. We compared postnatal growth in the first 18-months of life between children who are HIV-exposed uninfected (CHEU) with fetal exposure to ARV drugs (prophylaxis or triple-drug therapy (ART)) and CHEU not exposed to ARVs. We also examined other independent predictors of postnatal growth.Item HIV- and sex work-related stigmas and quality of life of female sex workers living with HIV in South Africa: A cross-sectional study(BMC, 2022) Chen, Claire; Baral, Stefan; Phetlhu, Dene ReniweBackground: Environmental quality of life (QoL) assesses individually perceived factors such as physical safety and security, accessibility, quality of healthcare, and physical environment. These factors are particularly relevant in the context of sex work and HIV, where stigma has been identified as an important barrier across several prevention and treatment domains. This study aims to examine the association between different types of HIV- and sex work-related stigmas and environmental QoL among female sex workers (FSW) living with HIV in Durban, South AfricaItem Role of religious beliefs on antiretroviral treatment adherence among Pentecostal Christians in sub Saharan Africa: a scoping review protocol(BMJ, 2021) Azia, Ivo; Shernaaz, Carelse; Nyembezi, AnamSub-Saharan Africa continues to be disproportionately affected by HIV/AIDS. As such, several countries in sub-Saharan Africa are implementing the UNAIDS’ recommendation to test and treat people living with HIV (PLHIV) irrespective of their CD4 count. However, most of the antiretroviral treatment (ART) programmes, in this region, continue to struggle with poor adherence to treatment stemming from patient-related factors including their religious beliefs. Unfortunately, the role of religious beliefs on ART adherence has been underexplored in the literature. In this study protocol, we propose the steps of a scoping review to explore, identify and map the literature on the impact of religious beliefs on adherence to ART among Pentecostals living with HIV in sub-Saharan Africa. Methods and analysis We will use Arksey and O’Malley’s framework and the Joanna Briggs Institute methodology guidelines to conduct this scoping review. The following databases will be searched for relevant literature: Web of Science, PubMed/Medline, Psych-ARTICLES, Academic Search Complete, Cumulative Index of Nursing, Allied Health, Google Scholar and published articles from conference proceedings. Studies published between January 2010 and February 2022 will be eligible. The identified literature will be independently screened for eligibility by two reviewers based on predetermined inclusion and exclusion criteria. An Excel form will be designed to electronically capture data from studies that meet the inclusion criteria. Finally, we will use a narrative synthesis to summarise the data extracted to report on the nature of existing evidence and the impact of religious beliefs on ART adherence. Ethics and dissemination Ethical approval will not be required for the scoping review since it will entail synthesising information from already published articles and conference proceedings. The study findings will be disseminated through publication in a scientific journal and presented at conferences and workshops aimed at improving adherence to ART in PLHIV.Item Integrating gestational diabetes and type 2 diabetes care into primary health care: Lessons from prevention of mother-to-child transmission of HIV in South Africa - A mixed methods study(Public Library of Science, 2021) Mutabazi, J C; Bonong, P R E; Trottier, H; Zarowsky, CBackground Implementation of the programmes for the Prevention of Mother to Child Transmission (PMTCT) of Human Immunodeficiency Virus (HIV) into antenatal care over the last three decades could inform implementation of interventions for other health challenges such as gestational diabetes mellitus (GDM). This study assessed PMTCT outcomes, and how GDM screening, care, and type 2 diabetes (T2DM) prevention were integrated into PMTCT in Western Cape (WC), South Africa. Methods A convergent mixed methods and triangulation design were used. Content and thematic analysis of PMTCT-related policy documents and of 30 semi-structured interviews with HIV/PMTCT experts, health care workers and women under PMTC diagnosed with GDM complement quantitative longitudinal analysis of PMTCT implementation indicators across the WC for 2012–2017. Results Provincial PMTCT and Post Natal Care (PNC) documents emphasized the importance of PMTCT, but GDM screening and T2DM prevention were not covered. Data on women with both HIV and GDM were not available and GDM screening was not integrated into PMTCT. Women who attended HIV counselling and testing annually increased at 17.8% (95% CI: 12.9% - 22.0%), while women who delivered under PMTCT increased at 3.1% (95% CI: 0.6% - 5.9%) annually in the WC. All 30 respondents favour integrating GDM screening and T2DM prevention initiatives into PMTCT. Conclusion PMTCT programmes have not yet integrated GDM care. However, Western Cape PMTCT integration experience suggests that antenatal GDM screening and post-partum initiatives for preventing or delaying T2DM can be successfully integrated into PMTCT and primary careItem Permeation challenges of drugs for treatment of neurological tuberculosis and HIV and the application of magneto-electric nanoparticle drug delivery systems(MDPI, 2021) Fisher, David W.; Tchoula Tchokonte, Moise B.; Dube, Admire; Mhambi, SinayeThe anatomical structure of the brain at the blood-brain barrier (BBB) creates a limitation for the movement of drugs into the central nervous system (CNS). Drug delivery facilitated by magneto-electric nanoparticles (MENs) is a relatively new non-invasive approach for the delivery of drugs into the CNS. These nanoparticles (NPs) can create localized transient changes in the permeability of the cells of the BBB by inducing electroporation. MENs can be applied to deliver antiretrovirals and antibiotics towards the treatment of human immunodeficiency virus (HIV) and tuberculosis (TB) infections in the CNS. This review focuses on the drug permeation challenges and reviews the application of MENs for drug delivery for these diseases. We conclude that MENs are promising systems for effective CNS drug delivery and treatment for these diseases, however, further preclinical and clinical studies are required to achieve translation of this approach to the clinic. © 2021 by the authors.

Aim: The aim of this study was to determine if age, body weight, height, gender, waist-to-hip ratio (WHR), educational attainment, employment status, CD4+ cell count and body mass index (BMI) can predict overall PA among PLWHA of low socio-economic status (SES). Setting: Participants in this study were HIV-infected patients on first-line antiretroviral therapy (ART) regimen offered by the South African National Department of Health, and those not on ART. Participants were conveniently sampled from a list at a community health care centre in Cape Town. Methods: This study sample consisted of 978 HIV-infected South Africans. Physical activity data were collected using the Global Physical Activity Questionnaire. Backward multiple linear regression modelling was used to determine the relative influence of variables (age, body weight, height, gender, WHR, educational attainment, employment status, CD4+ count and BMI) on total moderate-to-vigorous PA. Alpha level was set at 0.05. Results: The mean age of the participants was 38.2 (standard deviation [SD] = 8.76) years for men and 33.9 (SD = 8.53) years for women. Physical activity was significantly higher in men (480.2 [SD = 582.9] min/week) than among women (369.35 [SD = 222.53] min/week). The results of the multiple linear regression showed that educational attainment (β = 0.127; p = 0.00), employment (β = −0.087; p = 0.01) and gender (β = 0.235; p = 0.00) significantly predicted total moderate-to-vigorous PA. Gender had the greatest effect, followed by educational attainment and employment status. Conclusion: There is a need for PA programmes that are designed to (1) target women, (2) strengthen programmes for education and promotion of PA and (3) engage the unemployed into PA for PLWHA. Physical activity interventions for this particular group should be tailored for persons of low SES.Item Reflections of ART policy and its implementation: rebuilding the ship as we sail?(University of the Free State, 2006) Schneider, HelenThis paper reflects on the early experience with ART implementation in South Africa in the light of the policy goals of increasing ART access whilst improving prevention and strengthening the public health system. It reviews evidence on the state of ART roll-out and suggests that achievements to date have been significant, even if unevenly distributed and not meeting the set targets. The paper then considers what may be important future challenges - ensuring sustainable financing, addressing health system weaknesses (especially those related to human resources), building integrated systems of care and prevention, and developing appropriate national stewardship of the programme. Dealing with these challenges will be essential, both for building equitable ART access and leveraging wider benefits from the large investments in ART.Item Reorienting adolescent sexual and reproductive health research: reflections from an international conference(BioMed Central, 2016) Michielsen, Kristien; De Meyer, Sara; Ivanova, Olena; Anderson, Ragnar; Decat, Peter; Herbiet, Céline; Kabiru, Caroline W.; Ketting, Evert; Lees, JamesOn December 4th 2014, the International Centre for Reproductive Health (ICRH) at Ghent University organized an international conference on adolescent sexual and reproductive health (ASRH) and well-being. This viewpoint highlights two key messages of the conference - 1) ASRH promotion is broadening on different levels and 2) this broadening has important implications for research and interventions – that can guide this research field into the next decade. Adolescent sexuality has long been equated with risk and danger. However, throughout the presentations, it became clear that ASRH and related promotion efforts are broadening on different levels: from risk to well-being, from targeted and individual to comprehensive and structural, from knowledge transfer to innovative tools. However, indicators to measure adolescent sexuality that should accompany this broadening trend, are lacking. While public health related indicators (HIV/STIs, pregnancies) and their behavioral proxies (e.g. condom use, number of partners) are well developed and documented, there is a lack of consensus on indicators for the broader construct of adolescent sexuality, including sexual well-being and aspects of positive sexuality. Furthermore, the debate during the conference clearly indicated that experimental designs may not be the only appropriate study design to measure effectiveness of comprehensive, context-specific and long-term ASRH programmes, and that alternatives need to be identified and applied. Presenters at the conference clearly expressed the need to develop validated tools to measure different sub-constructs of adolescent sexuality and environmental factors. There was a plea to combine (quasi-)experimental effectiveness studies with evaluations of the development and implementation of ASRH promotion initiatives.Item Collective efficacy and HIV Prevention in South African Townships(National Institute of Health, 2013) Cain, Demetria; Pitpitan, Eileen V.; Mwaba, Kelvin; Eaton, Lisa; Carey, Kate B.; Carey, Michael P.; Mehlomakulu, Vuyelwa; Harel, Ofer; Simbayi, Leickness; Kalichman, Seth C.South African townships have high HIV prevalence and a strong need for collective action to change normative sexual risk behaviors. This study investigated the relationship between perceptions of individuals about collective efficacy in the community’s ability to prevent HIV and their personal HIV risk behaviors. Men (n=1581) and women (n=718) completed anonymous surveys within four Black African Townships in Cape Town, South Africa from June 2008 to December 2010. Measures included demographics, alcohol use, attitudinal and behavioral norms, sexual health communications, and sexual risk behaviors. In multivariate logistic regressions, men were more likely to endorse collective efficacy if they were married, drank less often in alcohol serving establishments, believed that fewer men approve of HIV risk behaviors, talk more with others about HIV/AIDS, and had more sex partners in the past month. Women were more likely to endorse collective efficacy if they drank alcohol less often, talked more with others about HIV/ AIDS, had more sex partners in the past month, but reported fewer unprotected sex acts in the past month. Community level interventions that strengthen collective efficacy beliefs will have to consider both protective and risk behaviors associated with believing that the community is ready and capable of preventing HIV.Item No one knows what will happen after these five years': narratives of ART, access and agency in Nigeria(Sage Publications, 2013) Omenka, Charity; Zarowski, ChristinaRural Nigerians pursue a range of strategies to maximize current and future access to HIV treatment in the context of securing livelihoods and minimizing the social and economic risks of stigma. This study reports on qualitative interviews with service providers and anti-retroviral therapy (ART) patients accessing care in Benue State, Nigeria, or travelling several hours to Abuja for treatment (n = 34). Nigerians living with HIV are keenly aware of the fragility and complex global and local politics of funding. Their narratives of pervasive stigma, economic and health system barriers to access, growing fears that free ART will cease, and strategies to secure access to care reveal a sophisticated synthesis of social determinants of health and clinical care, and challenge practitioners, planners, and scholars to take a similarly robust and nuanced approach to vulnerability, access, and agency.Item Between HIV diagnosis and initiation of antiretroviral therapy: Assessing the effectiveness of care for people living with HIV in the public primary care service in Cape Town, South Africa(Wiley-Blackwell, 2011) Scott, Vera; Zweigenthal, Virginia; Jennings, KarenBACKGROUND: While much is written about the scale up of HIV counselling and testing (HCT) and antiretroviral therapy (ART), little research has been done on the expansion of routine preART HIV care. OBJECTIVE: To assess the quality of preART care in Cape Town and its continuity with HCT and ART. METHODS: The scale up of the HCT, preART and ART service platform and programmatic support in Cape Town is described. Data from the August 2010 routine annual HIV/TB/STI evaluation, from interviews with 133 facility managers and a folder review of 634 HCT s who tested positive and 1115 clients receiving preART HIV care are analysed. RESULTS: Historically the implementation and management of preART care has been relatively neglected compared with the scale-up of HCT and ART. The CD4 count was done on 77.5% positive HCT clients and 46.6% were clinically staged - crucial steps that determine the care path. There were: gaps in quality of care - 32.2% of women had a PAP smear; missed opportunities for integrated care - 67% were symptomatically screened for tuberculosis; and positive prevention - 48.3% had contraceptive needs assessed. Breaks in the continuity of care of preART clients occurred with only 47.2% of eligible clients referred appropriately to the ARV service. CONCLUSION: While a package of preART care has been clearly defined in Cape Town, it has not been fully implemented. There are weaknesses in the continuity and quality service delivered that undermine the programme objectives of provision of positive prevention and timeous access to ART.
