Opportunities for technologically driven dialogical health communication for participatory interventions: Perspectives from male peer navigators in rural South Africa

There is increasing interest in the potential to deliver participatory dialogical HIV and intimate partner violence (IPV) prevention interventions via digital platforms, though the majority of mHealth interventions have been didactic in approach. We undertook 10 in-depth interviews with male Peer Navigators (PNs) who had been extensively trained and working on a larger intervention promoting young people's sexual and reproductive rights, in rural KwaZulu-Natal. Interviews focused on their, and their peers', use of technology in their everyday lives. Data were transcribed and translated, and subjected to thematic analysis. PNs described structural barriers to the use of technology, including poor connectivity, high data costs, and erratic electricity. They primarily used Facebook and WhatsApp for communication and highlighted how reading messages asynchronously was important to overcome connectivity challenges. PNs shared how groups were primarily for information sharing, they also discussed 'sensitive' issues online. Privacy was a concern, especially for conversations, and there was recognition of how confidentiality could be breached. It was also felt that WhatsApp could potentially support greater openness in discussions. We reflect on the potential for online interventions to support dialogical health communication, highlighting how dialogical health communication may be enabled through information provision, the asynchronous communication enhancing the potential for reflection, and greater participation in discussion by those who are shyer. Despite this potential there remain important risks around privacy of discussions and how to implement these approaches online

Generation and characterization of infectious molecular clones of transmitted/founder HIV-1 subtype C viruses

The genetic diversity of HIV impedes vaccine development. Identifying the viral properties of transmitted/founder (T/F) variants may provide a common vaccine target. To study the biological nature of T/F viruses, we constructed full-length clones from women detected during Fiebig stage I acute HIV-1 infection (AHI) from heterosexual male-to-female (MTF) transmission; and clones after one year of infection using In-Fusion-based cloning. Eighteen full-length T/F clones were generated from 9 women and six chronic infection clones were from 2 individuals. All clones but one were non-recombinant subtype C. Three of the 5 T/F clones and 3 chronic clones tested replicated efficiently in PBMCs and utilised CCR5 coreceptor for cell entry. Transmitted/founder and chronic infection clones displayed heterogenous in vitro replicative capacity and resistance to type I interferon. T/F viruses had shorter Env glycoproteins and fewer N-linked glycosylation sites in Env. Our findings suggest MTF transmission may select viruses with compact envelopes

Adaptation and pre-test of a shortened Stepping Stones and Creating Futures intervention focused on HIV for young men in rural South Africa

This is the final version. Available on open access from Public Library of Science via the DOI in this recordData Availability: All data are available via the AHRI data repository: https://data.ahri.org/index.php/home with access based on their guidelines.Men’s engagement in HIV prevention and treatment is suboptimal, including in South Africa. We sought to address this through adapting an evidence-based intervention, Stepping Stones and Creating Futures (SSCF), to strengthen its HIV content and provide a more scalable (shorter) intervention in rural South Africa. We then conducted a mixed methods pre-test of the intervention among young men aged 18–35 years. To adapt SSCF, we reviewed the current evidence base and worked with male Peer Navigators to update the SSCF theory of change (ToC) and manual. The revised intervention was ~45 hours (9 sessions) as opposed to ~63 hours and included a greater focus on HIV prevention and treatment technologies. Overall, 64% (n = 60) of men approached agreed to participate in the intervention, uptake (attending one session) among those who agreed was n = 35(58%) and retention (attending 6 or more sessions) was n = 25(71%). Qualitative data emphasized the intervention was acceptable, with young men describing it as something they liked. The qualitative data also broadly supported the intervention ToC, including the normalization of HIV in men’s lives, and the importance of health for men in achieving their life goals. However, it also highlighted the need to focus more on HIV-related stigma and fear, and the importance of HIV self-testing kits in encouraging testing. We revised the ToC and manual in light of this data. The adapted SSCF is acceptable and supports the ToC. Next steps is an evaluation to look at effectiveness of the intervention.Medical Research Council (MRC)Wellcome TrustNational Institutes of Health (NIH)South African Medical Research Counci

A Phase 2b Study to Evaluate the Safety and Efficacy of VRC01 Broadly Neutralizing Monoclonal Antibody in Reducing Acquisition of HIV-1 Infection in Women in Sub-Saharan Africa: Baseline Findings

Background: HIV Vaccine Trials Network 703/HIV Prevention Trials Network 081 is a phase 2b randomized, double-blind, placebo-controlled trial to assess the safety and efficacy of passively infused monoclonal antibody VRC01 in preventing HIV acquisition in heterosexual women between the ages of 18 and 50 years at risk of HIV. Participants were enrolled at 20 sites in Botswana, Kenya, Malawi, Mozambique, South Africa, Tanzania, and Zimbabwe. It is one of the 2 Antibody Mediated Prevention efficacy trials, with HIV Vaccine Trials Network 704/HIV Prevention Trials Network 085, evaluating VRC01 for HIV prevention. Methods: Intense community engagement was used to optimize participant recruitment and retention. Participants were randomly assigned to receive intravenous VRC01 10 mg/kg, VRC01 30 mg/kg, or placebo in a 1:1:1 ratio. Infusions were given every 8 weeks with a total of 10 infusions and 104 weeks of follow-up after the first infusion. Results: Between May 2016 and September 2018, 1924 women from sub-Saharan Africa were enrolled. The median age was 26 years (interquartile range: 22-30), and 98.9% were Black. Sexually transmitted infection prevalence at enrollment included chlamydia (16.9%), trichomonas (7.2%), gonorrhea (5.7%), and syphilis (2.2%). External condoms (83.2%) and injectable contraceptives (61.1%) were the methods of contraception most frequently used by participants. In total, through April 3, 2020, 38,490 clinic visits were completed with a retention rate of 96% and 16,807 infusions administered with an adherence rate of 98%. Conclusions: This proof-of-concept, large-scale monoclonal antibody study demonstrates the feasibility of conducting complex trials involving intravenous infusions in high incidence populations in sub-Saharan Africa

Oral abstracts of the 21st International AIDS Conference 18-22 July 2016, Durban, South Africa

The rate at which HIV-1 infected individuals progress to AIDS is highly variable and impacted by T cell immunity. CD8 T cell inhibitory molecules are up-regulated in HIV-1 infection and associate with immune dysfunction. We evaluated participants (n=122) recruited to the SPARTAC randomised clinical trial to determine whether CD8 T cell exhaustion markers PD-1, Lag-3 and Tim-3 were associated with immune activation and disease progression.Expression of PD-1, Tim-3, Lag-3 and CD38 on CD8 T cells from the closest pre-therapy time-point to seroconversion was measured by flow cytometry, and correlated with surrogate markers of HIV-1 disease (HIV-1 plasma viral load (pVL) and CD4 T cell count) and the trial endpoint (time to CD4 count <350 cells/μl or initiation of antiretroviral therapy). To explore the functional significance of these markers, co-expression of Eomes, T-bet and CD39 was assessed.Expression of PD-1 on CD8 and CD38 CD8 T cells correlated with pVL and CD4 count at baseline, and predicted time to the trial endpoint. Lag-3 expression was associated with pVL but not CD4 count. For all exhaustion markers, expression of CD38 on CD8 T cells increased the strength of associations. In Cox models, progression to the trial endpoint was most marked for PD-1/CD38 co-expressing cells, with evidence for a stronger effect within 12 weeks from confirmed diagnosis of PHI. The effect of PD-1 and Lag-3 expression on CD8 T cells retained statistical significance in Cox proportional hazards models including antiretroviral therapy and CD4 count, but not pVL as co-variants.Expression of ‘exhaustion’ or ‘immune checkpoint’ markers in early HIV-1 infection is associated with clinical progression and is impacted by immune activation and the duration of infection. New markers to identify exhausted T cells and novel interventions to reverse exhaustion may inform the development of novel immunotherapeutic approaches

Towards A User Friendly Library for Students with Disabilities: Opportunities and Challenges at Teachers’ Colleges in Zimbabwe

This study sought to explore the usability of library facilities to students with disabilities at Zimbabwe’s teacher education colleges. The study intended to find ways of establishing user friendly libraries at these institutions. The study focused on one of the thirteen national teacher education colleges in Zimbabwe, that is, United College of Education (UCE). A qualitative research design in the form of a case study was adopted where the use of semi-structured questionnaires and interview guides enabled the researchers to gather views of the participants about the phenomenon under study. The purposive sampling technique was used to target the library staff and the students with disabilities as the information-rich participants for the study. The entire studied sample was 30 participants. Some of the critical findings included lack of adequate infrastructural and physical development to promote a user friendly library for students with disabilities, lack of expertise within the library staff and inadequate computer software for students with disabilities. Negative attitudes by some of the library staff members and fellow non-disabled students towards students with disabilities also threaten the user-friendliness of the library. It is therefore recommended that periodical staff development sessions for the library staff be conducted. The study also recommends for the college’s administration to consider the refurbishment of the library’s infrastructure and information system in its strategic plans. A reserve section in the library for students with disabilities will also be a progressive move

A qualitative study to explore mother’s experiences of a family MUAC project in two provinces in South Africa

Abstract Background In South Africa, severe acute malnutrition remains a significant cause of child mortality. Measuring mid-upper arm circumference (MUAC) is a simple, cost-effective approach to identify malnutrition in communities. The Family MUAC intervention supported community health workers (CHWs) to mentor mothers and child caregivers to measure MUAC, record their findings and access nutrition information from the child’s Road-to-Health-Book. Family MUAC was implemented in seven sites in two provinces in South Africa: Gauteng and KwaZulu-Natal. This study aimed to explore mother/caregiver’s perceptions and experiences of participating in Family MUAC. Methods Focus group discussions (FGDs) were conducted with mothers purposively selected by CHWs based on their active participation in Family MUAC. Trained qualitative researchers conducted one FGD at each participating site. Coding reliability thematic analysis with topic summaries was employed to analyse the data using Nvivo v12. Results Seven FGDs were conducted with a total of 59 participants. Key themes identified were mother’s perceptions of the CHW’s role, experiences of implementing Family MUAC activities, and perceptions of the broader effect on maternal empowerment and child health. Mothers appreciated the support from CHWs who were perceived as patient and caring, taking time to develop mother’s skills and answer questions. CHWs provided ongoing care, encouraged participation and understood the mother’s home situation. Mothers experienced group learning positively, and helped each other learn about MUAC measurements. Most mothers experienced measuring MUAC as challenging initially, needing support from CHWs to gain confidence to measure and record findings. Participating in Family MUAC empowered mothers in caring for their child, and improved their relationships with CHWs. Mothers compared support from CHWs to care received at the clinic, saying clinic visits were costly and time-consuming and nurses frequently did not explain their findings. Mothers reported feeling more confident to ask questions during clinic visits after participating in family MUAC. Conclusions Using CHWs to support mothers measuring MUAC in households was acceptable and feasible. CHWs provided ongoing good quality care, relevant advice and support, and empowered mothers. Family MUAC had wide ranging benefits for building relationships and peer support in communities and strengthened mothers perceived role in the care of her child

Attitudes and perceptions about breastfeeding among female and male informal workers in India and South Africa

Abstract Background Worldwide, over 740 million women make their living in the informal economy and therefore lack formal employment benefits, such as maternity leave, that can improve infant feeding practices. Returning to work is one of the biggest challenges women face to maintaining breastfeeding. This study aimed to explore attitudes and perceptions towards breastfeeding in the informal work environment among male and female informal workers. Methods The study used a qualitative research design. Purposive and snowball sampling was employed. Focus group discussions (FGDs) were conducted among men and women working in different types of informal jobs, in India and South Africa. Data was analysed using a thematic approach and the framework method. Results Between March and July 2017, 14 FGDs were conducted in South Africa and nine in India. Most women were knowledgeable about the benefits of breastfeeding and reported initiating breastfeeding. However, pressures of family responsibilities and household financial obligations frequently forced mothers to return to work soon after childbirth. Upon return to work many mothers changed their infant feeding practices, adding breastmilk substitutes like formula milk, buffalo milk, and non-nutritive fluids like Rooibos tea. Some mothers expressed breastmilk to feed the infant while working but many mothers raised concerns about expressed breastmilk becoming ‘spoilt’. Breastfeeding in the workplace was challenging as the work environment was described as unsafe and unhygienic for breastfeeding. Mothers also described being unable to complete work tasks while caring for an infant. In contrast, the flexibility of informal work allowed some mothers to successfully balance competing priorities of childcare and work. Sociocultural challenges influenced breastfeeding practices. For example, men in both countries expressed mixed views about breastfeeding. Breastfeeding was perceived as beneficial for both mother and child, however it was culturally unacceptable for women to breastfeed in public. This affected working mothers’ ability to breastfeed outside the home and contributed to a lack of respect for women who chose to breastfeed in the workplace. Conclusion Mothers working in the informal sector face multiple challenges to maintaining breastfeeding. Interventions are required to support feeding and childcare if global nutrition and development goals are to be met. </jats:sec

Electronic Integrated Management of Childhood Illness (eIMCI): a randomized controlled trial to evaluate an electronic clinical decision-making support system for management of sick children in primary health care facilities in South Africa

Abstract Background Electronic clinical decision-making support systems (eCDSS) aim to assist clinicians making complex patient management decisions and improve adherence to evidence-based guidelines. Integrated management of Childhood Illness (IMCI) provides guidelines for management of sick children attending primary health care clinics and is widely implemented globally. An electronic version of IMCI (eIMCI) was developed in South Africa. Methods We conducted a cluster randomized controlled trial comparing management of sick children with eIMCI to the management when using paper-based IMCI (pIMCI) in one district in KwaZulu-Natal. From 31 clinics in the district, 15 were randomly assigned to intervention (eIMCI) or control (pIMCI) groups. Computers were deployed in eIMCI clinics, and one IMCI trained nurse was randomly selected to participate from each clinic. eIMCI participants received a one-day computer training, and all participants received a similar three-day IMCI update and two mentoring visits. A quantitative survey was conducted among mothers and sick children attending participating clinics to assess the quality of care provided by IMCI practitioners. Sick child assessments by participants in eIMCI and pIMCI groups were compared to assessment by an IMCI expert. Results Self-reported computer skills were poor among all nurse participants. IMCI knowledge was similar in both groups. Among 291 enrolled children: 152 were in the eIMCI group; 139 in the pIMCI group. The mean number of enrolled children was 9.7 per clinic (range 7-12). IMCI implementation was sub-optimal in both eIMCI and pIMCI groups. eIMCI consultations took longer than pIMCI consultations (median duration 28 minutes vs 25 minutes; p = 0.02). eIMCI participants were less likely than pIMCI participants to correctly classify children for presenting symptoms, but were more likely to correctly classify for screening conditions, particularly malnutrition. eIMCI participants were less likely to provide all required medications (124/152; 81.6% vs 126/139; 91.6%, p= 0.026), and more likely to prescribe unnecessary medication (48/152; 31.6% vs 20/139; 14.4%, p = 0.004) compared to pIMCI participants. Conclusions Implementation of eIMCI failed to improve management of sick children, with poor IMCI implementation in both groups. Further research is needed to understand barriers to comprehensive implementation of both pIMCI and eIMCI. (349) Clinical trials registration Clinicaltrials.gov ID: BFC157/19, August 2019
