    There is limited evidence on the acceptability, feasibility and cost-effectiveness of task-sharing interventions to narrow the treatment gap for mental disorders in sub-Saharan Africa. The purpose of this article is to describe the rationale, aims and methods of the Africa Focus on Intervention Research for Mental health (AFFIRM) collaborative research hub. AFFIRM is investigating strategies for narrowing the treatment gap for mental disorders in sub-Saharan Africa in four areas. First, it is assessing the feasibility, acceptability and cost-effectiveness of task-sharing interventions by conducting randomised controlled trials in Ethiopia and South Africa. The AFFIRM Task-sharing for the Care of Severe mental disorders (TaSCS) trial in Ethiopia aims to determine the acceptability, affordability, effectiveness and sustainability of mental health care for people with severe mental disorder delivered by trained and supervised non-specialist, primary health care workers compared with an existing psychiatric nurse-led service. The AFFIRM trial in South Africa aims to determine the cost-effectiveness of a task-sharing counselling intervention for maternal depression, delivered by non-specialist community health workers, and to examine factors influencing the implementation of the intervention and future scale up. Second, AFFIRM is building individual and institutional capacity for intervention research in sub-Saharan Africa by providing fellowship and mentorship programmes for candidates in Ethiopia, Ghana, Malawi, Uganda and Zimbabwe. Each year five Fellowships are awarded (one to each country) to attend the MPhil in Public Mental Health, a joint postgraduate programme at the University of Cape Town and Stellenbosch University. AFFIRM also offers short courses in intervention research, and supports PhD students attached to the trials in Ethiopia and South Africa. Third, AFFIRM is collaborating with other regional National Institute of Mental Health funded hubs in Latin America, sub-Saharan Africa and south Asia, by designing and executing shared research projects related to task-sharing and narrowing the treatment gap. Finally, it is establishing a network of collaboration between researchers, non-governmental organisations and government agencies that facilitates the translation of research knowledge into policy and practice. This article describes the developmental process of this multi-site approach, and provides a narrative of challenges and opportunities that have arisen during the early phases. Crucial to the long-term sustainability of this work is the nurturing and sustaining of partnerships between African mental health researchers, policy makers, practitioners and international collaborators

    We present a catalog of 4195 optically confirmed Sunyaev–Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise ratio >4 in 13,211 deg2 of sky surveyed by the Atacama Cosmology Telescope (ACT). Cluster candidates were selected by applying a multifrequency matched filter to 98 and 150 GHz maps constructed from ACT observations obtained from 2008 to 2018 and confirmed using deep, wide-area optical surveys. The clusters span the redshift range 0.04 1 clusters, and a total of 868 systems are new discoveries. Assuming an SZ signal versus mass-scaling relation calibrated from X-ray observations, the sample has a 90% completeness mass limit of M500c > 3.8 × 1014 M⊙, evaluated at z = 0.5, for clusters detected at signal-to-noise ratio >5 in maps filtered at an angular scale of 2farcm4. The survey has a large overlap with deep optical weak-lensing surveys that are being used to calibrate the SZ signal mass-scaling relation, such as the Dark Energy Survey (4566 deg2), the Hyper Suprime-Cam Subaru Strategic Program (469 deg2), and the Kilo Degree Survey (825 deg2). We highlight some noteworthy objects in the sample, including potentially projected systems, clusters with strong lensing features, clusters with active central galaxies or star formation, and systems of multiple clusters that may be physically associated. The cluster catalog will be a useful resource for future cosmological analyses and studying the evolution of the intracluster medium and galaxies in massive clusters over the past 10 Gyr

    Background: Integration of services in primary health care settings can provide mother/baby pairs with all required services at one visit. This study aimed to evaluate a proof of concept, quality improvement (QI) intervention to strengthen well-child service provision and integration with maternal health services in five rural clinics in KwaZulu-Natal, South Africa.Methods: Quantitative cross-sectional surveys were conducted among mothers bringing their child for well-child services, before and after implementation of the intervention. Exit interviews and reviews of the child’s Road to Health Booklet (RTHB) were conducted to determine services provided at the visit, and the time spent in the clinic was observed and recorded.Results: A total of 413 exit interviews and record reviews were conducted (123 at baseline and 290 at follow-up). At follow-up, significantly more mothers were tested for HIV during the well-child visit (9.2% vs. 22.6%; p = 0.045) and significantly more mothers received ART (3.7% vs. 35.5%; p = 0.010). However, coverage of growth-monitoring services remained low and there was no difference in infant feeding advice provided to mothers at baseline and follow-up (49.5% vs. 49.7%; p = 0.996). More mothers interacted with a registered nurse at follow-up than at baseline (35.8% vs. 80.7%; p = 0.032).Conclusions: Over the implementation period of the QI intervention, improvement was shown in coverage and quality of some maternal health and HIV services, but there was no improvement in growth monitoring. This suggests that QI has the potentialto improve integration of service delivery, but this was a small study and further research is recommended

    Rates of pregnancy and HIV infection are high among South African adolescents, yet little is known about rates of mother-to-child transmission of HIV (MTCT) in this group. We report a comparison of the characteristics of adolescent mothers and adult mothers, including HIV prevalence and MTCT rates.We examined patterns of health service utilization during the antenatal and early postnatal period, HIV prevalence and MTCT amongst adolescent (<20-years-old) and adult (20 to 39-years-old) mothers with infants aged ≤16 weeks attending immunization clinics in six districts of KwaZulu-Natal between May 2008 and April 2009.Interviews were conducted with 19,093 mothers aged between 12 and 39 years whose infants were aged ≤16 weeks. Most mothers had attended antenatal care four or more times during their last pregnancy (80.3%), and reported having an HIV test (98.2%). A greater proportion of HIV-infected adult mothers, compared to adolescent mothers, reported themselves as HIV-positive (41.2% vs. 15.9%, p<0.0001), reported having a CD4 count taken during their pregnancy (81.0% vs. 66.5%, p<0.0001), and having received the CD4 count result (84.4% vs. 75.7%, p<0.0001). Significantly fewer adolescent mothers received the recommended PMTCT regimen. HIV antibody was detected in 40.4% of 7,800 infants aged 4-8 weeks tested for HIV, indicating HIV exposure. This was higher among infants of adult mothers (47.4%) compared to adolescent mothers (17.9%, p<0.0001). The MTCT rate at 4-8 weeks of age was significantly higher amongst infants of adolescent mothers compared to adult mothers (35/325 [10.8%] vs. 185/2,800 [6.1%], OR 1.7, 95% CI 1.2-2.4).Despite high levels of antenatal clinic attendance among pregnant adolescents in KwaZulu-Natal, the MTCT risk is higher among infants of HIV-infected adolescent mothers compared to adult mothers. Access to adolescent-friendly family planning and PMTCT services should be prioritised for this vulnerable group

    Introduction: In South Africa fewer health professionals (HPs) work in rural areas compared to urban areas, despite rural communities having greater health needs. This study explores factors influencing recruitment and retention of three categories of HPs in KwaZulu-Natal and has implications about how to retain them in rural areas. Methods: A cross-sectional, descriptive survey was conducted in 8 hospitals, 5 rural and 3 urban, in one district in KZN in 2011. Data were collected on single day in each hospital and all HPs on duty were requested to participate. We compared responses from rural and urban based HP as well as professional nurses (PNs), doctors, and allied HPs. Results: 417 questionnaires were completed: 150 from HPs in rural and 267 from HPs in urban hospitals. Perceptions of living/working in rural areas is negative and the quality of health care provided in rural areas is perceived as poor by all categories of HP. Rural-basedHPs were more likely to report living apart from spouse/partner (72.1% vs 37.0%, p < 0.001)and children (76.7% vs 36.9%, p < 0.001), and living in hospital accommodation (50.8% vs 28.9%; p < 0.001). Conclusions: Decisions made by HP about where to work are complex, multifactorial and should be tailored to each category of health professional

    Background: Community health workers (CHWs) are a component of the health system in many countries, providing effective community-based services to mothers and infants. However, implementation of CHW programmes at scale has been challenging in many settings. Aim: To explore the acceptability of CHWs conducting household visits to mothers and infants during pregnancy and after delivery, from the perspective of community members, professional nurses and CHWs themselves. Setting: Primary health care clinics in five rural districts in KwaZulu-Natal, South Africa. Methods: A qualitative exploratory study was conducted where participants were purposively selected to participate in 19 focus group discussions based on their experience with CHWs or child rearing. Results: Poor confidentiality and trust emerged as key barriers to CHW acceptability in delivering maternal and child health services in the home. Most community members felt that CHWs could not be trusted because of their lack of professionalism and inability to maintain confidentiality. Familiarity and the complex relationships between household members and CHWs caused difficulties in developing and maintaining a relationship of trust, particularly in high HIV prevalence settings. Professional staff at the clinic were crucial in supporting the CHW’s role; if they appeared to question the CHW’s competency or trustworthiness, this seriously undermined CHW credibility in the eyes of the community. Conclusion: Understanding the complex contextual challenges faced by CHWs and community members can strengthen community-based interventions. CHWs require training, support and supervision to develop competencies navigating complex relationships within the community and the health system to provide effective care in communities
