Through scale-up of effective treatment and prevention, HIV incidence rates are falling across Southern and Eastern Africa. However, key population groups, including people living in fishing communities, continue to face an elevated risk of infection and have high rates of undiagnosed disease. We set out to investigate how intersecting inequalities make young fishermen working on the southern shores of Lake Malawi particularly vulnerable to HIV-infection. We used qualitative research methods including observations (over a 15-month period), in-depth interviews (59) and focus group discussions (16) with a range of male and female participants living and working in two fishing villages. We found that the roles that men occupied in the fishing industry depended on several factors, including their age, socio-economic position and the amount of experience they had in the industry. In turn these roles shaped their lives, including exposure to occupational risks, mobility, living conditions, economic remuneration and social standing within the community. In this context, younger and poorer men occupied roles with the lowest social standing in the industry. Nevertheless, in these communities where poverty was pervasive, young fishermen were able to exert the power they gained through access to money and fish over poorer younger women – pressuring them into sex and increasing the risk of HIV for both men and women. Drawing on an intersectionality framework, we contextualised these findings to consider how young men's social location, relationships and experiences of both privilege and marginalisation were shaped by broader economic and political processes. We conclude that interventions to prevent HIV in fishing communities need to address how power plays out in the broader social and economic environment.
Objectives Research is key to achieving global development goals. Our objectives were to develop and test an evidence-informed process for assessing health research management and support systems (RMSS) in four African universities and for tracking interventions to address capacity gaps. Setting Four African universities. Participants 83 university staff and students from 11 cadres. Intervention/methods A literature-informed 'benchmark' was developed and used to itemise all components of a university's health RMSS. Data on all components were collected during site visits to four African universities using interview guides, document reviews and facilities observation guides. Gaps in RMSS capacity were identified against the benchmark and institutional action plans developed to remedy gaps. Progress against indicators was tracked over 15 months and common challenges and successes identified. Results Common gaps in operational health research capacity included no accessible research strategy, a lack of research e-tracking capability and inadequate quality checks for proposal submissions and contracts. Feedback indicated that the capacity assessment was comprehensive and generated practical actions, several of which were no-cost. Regular follow-up helped to maintain focus on activities to strengthen health research capacity in the face of challenges. Conclusions Identification of each institutions' strengths and weaknesses against an evidence-informed benchmark enabled them to identify gaps in in their operational health research systems, to develop prioritised action plans, to justify resource requests to fulfil the plans and to track progress in strengthening RMSS. Use of a standard benchmark, approach and tools enabled comparisons across institutions which has accelerated production of evidence about the science of research capacity strengthening. The tools could be used by institutions seeking to understand their strengths and to address gaps in research capacity. Research capacity gaps that were common to several institutions could be a 'smart' investment for governments and health research funders.

BackgroundIn Southern Malawi, the fishing industry is highly gendered, with men carrying out the fishing and women processing, drying and selling the fish. Research has shown that individuals living in fishing communities in low‐income countries are particularly vulnerable to HIV infection. One of the key drivers of HIV in fishing communities is transactional sex. In the fishing industry this takes the form of "fish‐for‐sex" networks where female fish traders exchange sex with fishermen for access to or more favourable prices of fish. By controlling the means of production, the power dynamics in these exchanges favour men and can make it more difficult for women to negotiate safe sex.MethodsQualitative methods were used to collect data on gendered drivers of transactional sex in the fishing community and how different groups perceive HIV risk in these transactions. Observation, focus group discussions and semi‐structured interviews were undertaken with members of the fishing communities, including men and women directly and indirectly involved in fishing.ResultsIn fishing communities transactional sex was prevalent across a spectrum ranging from gift giving within relationships, to sex for fish exchanges, to sex worker encounters. Power differences between couples in transactional sexual encounters shape individual's abilities to negotiate condom use (with women being at a particularly disadvantaged negotiating position). The context and motivations for transactional sex varied and was mediated by economic need and social position both of men and women. Female fish traders new to the industry and boat crew members who travelled for work and experienced difficult living conditions often engaged in transactional sex.ConclusionsTransactional sex is common in Malawian fishing communities, with women particularly vulnerable in negotiations because of existing gendered power structures. Although knowledge and understanding of the HIV risk associated with transactional sex was common, this did not appear to result in the adoption of risk reduction strategies. This suggests that specially targeted strategies to increase women's economic empowerment and tackle the structural drivers of women's HIV risk could be important in fishing communities.
Background: Health systems have experienced unprecedented stress in recent years, and as yet no consensus has emerged as to how to deal with the multiple burden of disease in the context of HIV and AIDS and other competing health priorities. Priority setting is essential, yet this is a complex, multifaceted process. Drawing on a study conducted in five African countries, this paper explores different stakeholders′ perceptions of health priorities, how priorities are defined in practice, the process of resource allocation for HIV and Health and how different stakeholders perceive this. Methods: A sub-analysis was conducted of selected data from a wider qualitative study that explored the interactions between health systems and HIV and AIDS responses in five sub-Saharan countries (Burkina Faso, the Democratic Republic of Congo, Ghana, Madagascar and Malawi). Key background documents were analysed and semi-structured interviews (n = 258) and focus group discussions (n = 45) were held with representatives of communities, health personnel, decision makers, civil society representatives and development partners at both national and district level. Results: Health priorities were expressed either in terms of specific health problems and diseases or gaps in service delivery requiring a strengthening of the overall health system. In all five countries study respondents (with the exception of community members in Ghana) identified malaria and HIV as the two top health priorities. Community representatives were more likely to report concerns about accessibility of services and quality of care. National level respondents often referred to wider systemic challenges in relation to achieving the Millennium Development Goals (MDGs). Indeed, actual priority setting was heavily influenced by international agendas (e.g. MDGs) and by the ways in which development partners were supporting national strategic planning processes. At the same time, multi-stakeholder processes were increasingly used to identify priorities and inform ...
This study utilised qualitative research methodology to explore female fish traders' experiences of accessing microfinance in fishing communities in southern Malawi. Microfinance is a tool that has been used to alleviate poverty. People living in fishing communities in the Global South are at an increased risk of HIV and, equally, microfinance has been identified as a tool to prevent HIV. The authors' research found consistent testimonies of overly short microfinance loan-repayment periods, enforced by the threat of property confiscation. These threats, coupled with gendered power dynamics and the unpredictability of fish catches, left some female fish traders vulnerable to HIV.
AbstractIntroductionAntiretroviral therapy (ART) initiation in infants living with HIV before 12 weeks of age can reduce the risk of mortality by 75%. Point‐of‐care (POC) diagnostic testing is critical for prompt ART initiation; however, despite its availability, rates of ART initiation are still relatively low before 12 weeks of age. This systematic review describes the barriers to ART initiation in infants before 12 weeks of age, despite the availability of POC.MethodsThis systematic review used a narrative synthesis methodology. We searched PubMed and Scopus using search strategies that combined terms of multiple variants of the keywords "early infant initiation on antiretroviral therapy," "barriers" and "sub‐Saharan Africa" (initial search 18th January 2023; final search 1st August 2023). We included qualitative, observational and mixed methods studies that reported the influences of early infant initiation on ART. We excluded studies that reported influences on other components of the Prevention of Mother to Child Transmission cascade. Using a deductive approach guided by the updated Consolidated Framework of Implementation Research, we developed descriptive codes and themes around barriers to early infant initiation on ART. We then developed recommendations for interventions for the identified barriers using the action, actor, target and time framework from the codes.ResultsOf the 266 abstracts reviewed, 52 full‐text papers were examined, of which 12 papers were included. South Africa had most papers from a single country (n = 3) and the most reported study design was retrospective (n = 6). Delays in ART initiation beyond 12 weeks in infants 0–12 months were primarily associated with health facility and maternal factors. The most prominent barriers identified were inadequate resources for POC testing (including human resources, laboratory facilities and patient follow‐up). Maternal‐related factors, such as limited male involvement and maternal perceptions of treatment and care, were also influential.DiscussionWe identified structural barriers to ART initiation at the health system, social and cultural levels. Improvements in the timely allocation of resources for POC testing operations, coupled with interventions addressing social and behavioural barriers among both mothers and healthcare providers, hold a promise for enhancing timely ART initiation in infants.ConclusionsThis paper identifies barriers and proposes strategies for timely ART initiation in infants.
AbstractIntroductionDefinitions of retention‐in‐care in Prevention of Mother‐to‐Child Transmission of HIV (PMTCT) vary substantially between studies and programmes. Some definitions are based on visits missed/made, others on a minimum total number of visits, or attendance at a final clinic visit at a specific time. An agreed definition could contribute to developing evidence‐based interventions for improving retention‐in‐care. In this paper, we estimated retention‐in‐care rates according to different definitions, and we quantified and visualized the degree of agreement between definitions.MethodsWe calculated retention in care rates using nine definitions in the six INSPIRE PMTCT intervention studies, conducted in three sub‐Saharan African countries between 2013 and 2017. With data from one of the studies (E4E), we estimated the agreement between definitions using Gwet's agreement coefficient (AC1) and concordance. We calculated positive predictive values (PPV) and negative predictive values (NPV) for all definitions considering successively each definition as the reference standard. Finally, we used a Multiple Correspondence Analysis (MCA) to examine clustering of the way different definitions handle retention‐in‐care.ResultsRetention‐in‐care rates among 5107 women ranged from 30% to 76% in the complete dataset with Gwet's AC1 being 0.56 [0.53; 0.59] indicating a moderate agreement between all definitions together. Two pairs of definitions with high inner concordance and agreement had either very high PPV or very high NPV, and appeared distinct from the other five definitions on the MCA figures. These pairs of definitions were also the ones resulting in the lowest and highest estimates of retention‐in‐care. The simplest definition, that only required a final clinic visit to classify women as retained in care, and classified 55% of women as retained in care, had a PPV ranging from 0.7 to 1 and a NPV ranging from 0.69 to 0.98 when excluding the two pairs afore‐mentioned; it resulted in a moderate to substantial agreement and a 70% to 90% concordance with all other definitions.ConclusionsOur study highlights the variability of definitions in estimating retention‐in‐care. Some definitions are very stringent which may be required in some instances. A simple indicator such as attendance at a single time point may be sufficient for programme planning and evaluation.
Background Timely diagnosis of HIV in infants and children is an urgent priority. In Malawi, 40,000 infants annually are HIV exposed. However, gold standard polymerase-chain-reaction (PCR) based testing requires centralised laboratories, causing turn-around times (TAT) of 2 to 3 months and significant loss to follow-up. If feasible and acceptable, minimising diagnostic delays through HIV Point-of-care-testing (POCT) may be cost-effective. We assessed whether POCT Cepheid Xpert HIV-1 Qual assay whole blood (XpertHIV) was more cost-effective than PCR. Methods From July-August 2018, 700 PCR Abbott tests using dried blood spots (DBS) were performed on 680 participants who enrolled on the feasibility, acceptability and performance of the XpertHIV study. Newly identified HIV-positive DBS from the 680 participants were retested, so with confirmatory testing of the HIV-positive cases, 700 tests were performed. We conducted a cost-minimisation and cost-effectiveness analysis of XpertHIV against PCR, as the standard of care. A random sample of 200 caregivers from the 680 participants had semi-structured interviews to explore costs from a societal perspective of XpertHIV at Mulanje District Hospital, Malawi. Analysis used TAT as the primary outcome measure. Results were extrapolated from the study period (29 days) to a year (240 working days). Sensitivity analyses characterised individual and joint parameter uncertainty and estimated patient cost per test. Results During the study period, XpertHIV was cost-minimising at $42.34 per test compared to $66.66 for PCR. Over a year, XpertHIV remained cost-minimising at $16.12 compared to PCR at $27.06. From the patient perspective (travel, food, lost productivity), the cost per test of XpertHIV was $2.45. XpertHIV had a mean TAT of 7.10 hours compared to 153.15 hours for PCR. Extrapolates accounting for equipment costs, lab consumables and losses to follow up estimated annual savings of $2,193,538.88 if XpertHIV is used nationally, as opposed to PCR. Conclusions This preliminary evidence suggests that adopting POCT XpertHIV will save time, allowing HIV-exposed infants to receive prompt care and may improve outcomes. The Malawi government will pay less due to XpertHIV's cost savings and associated benefits.
Sulfadoxine-resistant Plasmodium falciparum undermines malaria prevention with sulfadoxine/pyrimethamine. Parasites with a highly resistant mutant dihydropteroate synthase (dhps) haplotype have recently emerged in eastern Africa; they negated preventive benefits of sulfadoxine/pyrimethamine, and might exacerbate placental malaria. We explored emerging lineages of dhps mutant haplotypes in Malawi, the Democratic Republic of the Congo, and Tanzania by using analyses of genetic microsatellites flanking the dhps locus. In Malawi, a triple-mutant dhps SGEG (mutant amino acids are underlined) haplotype emerged in 2010 that was closely related to pre-existing double-mutant SGEA haplotypes, suggesting local origination in Malawi. When we compared mutant strains with parasites from the Democratic Republic of the Congo and Tanzania by multiple independent analyses, we found that SGEG parasites were partitioned into separate lineages by country. These findings support a model of local origination of SGEG dhps haplotypes, rather than geographic diffusion, and have implications for investigations of emergence and effects of parasite drug resistance.
AbstractIntroductionWhile pregnant people have been an important focus for HIV research, critical evidence gaps remain regarding prevention, co‐infection, and safety and efficacy of new antiretroviral therapies in pregnancy. Such gaps can result in harm: without safety data, drugs used may carry unacceptable risks to the foetus or pregnant person; without pregnancy‐specific dosing data, pregnant people face risks of both toxicity and undertreatment; and delays in gathering evidence can limit access to beneficial next‐generation drugs. Despite recognition of the need, numerous barriers and ethical complexities have limited progress. We describe the process, ethical foundations, recommendations and applications of guidance for advancing responsible inclusion of pregnant people in HIV/co‐infections research.DiscussionThe 26‐member international and interdisciplinary Pregnancy and HIV/AIDS: Seeking Equitable Study (PHASES) Working Group was convened to develop ethics‐centred guidance for advancing timely, responsible HIV/co‐infections research with pregnant people. Deliberations over 3 years drew on extensive qualitative research, stakeholder engagement, expert consultation and a series of workshops. The guidance, initially issued in July 2020, highlights conceptual shifts needed in framing research with pregnant people, and articulates three ethical foundations to ground recommendations: equitable protection from drug‐related risks, timely access to biomedical advances and equitable respect for pregnant people's health interests. The guidance advances 12 specific recommendations, actionable within the current regulatory environment, addressing multiple stakeholders across drug development and post‐approval research, and organized around four themes: building capacity, supporting inclusion, achieving priority research and ensuring respect. The recommendations describe strategies towards ethically redressing the evidence gap for pregnant people around HIV and co‐infections. The guidance has informed key efforts of leading organizations working to advance needed research, and identifies further opportunities for impact by a range of stakeholder groups.ConclusionsThere are clear pathways towards ethical inclusion of pregnant people in the biomedical research agenda, and strong agreement across the HIV research community about the need for – and the promise of – advancing them. Those who fund, conduct, oversee and advocate for research can use the PHASES guidance to facilitate more, better and earlier evidence to optimize the health and wellbeing of pregnant people and their children.
Africa is experiencing an increasing prevalence of noncommunicable diseases (NCD). However, few reliable data are available on their true burden, main risk factors, and economic impact that are needed to inform implementation of evidence-based interventions in the local context. In Malawi, a number of initiatives have begun addressing the NCD challenge, which have often utilized existing infectious disease infrastructure. It will be crucial to carefully leverage these synergies to maximize their impact. NCD-BRITE (Building Research Capacity, Implementation, and Translation Expertise) is a transdisciplinary consortium that brings together key research institutions, the Ministry of Health, and other stakeholders to build longterm, sustainable, NCD-focused implementation research capacity. Led by University of Malawi—College of Medicine, University of North Carolina, and Dignitas International, NCD-BRITE's specific aims are to conduct detailed assessments of the burden and risk factors of common NCD; assess the research infrastructure needed to inform, implement, and evaluate NCD interventions; create a national implementation research agenda for priority NCD; and develop NCD-focused implementation research capacity through short courses, mentored research awards, and an internship placement program. The capacity-building activities are purposely designed around the University of Malawi—College of Medicine and Ministry of Health to ensure sustainability. The NCD BRITE Consortium was launched in February 2018. In year 1, we have developed NCD-focused implementation research capacity. Needs assessments will follow in years 2 and 3. Finally, in year 4, the generated research capacity, together with findings from the needs assessments, will be used to create a national, actionable, implementation research agenda for NCD prioritized in this consortium, namely cardiovascular disease, diabetes mellitus, and asthma and chronic obstructive pulmonary disease.HighlightsNCD-BRITE is a transdisciplinary consortium that brings together key research institutions, the MOH, and other stakeholders to build long-term, sustainable, NCD-focused implementation research capacity.NCD-BRITE's specific aims are to conduct detailed assessments of the burden and risk factors of common NCD (hypertension, diabetes mellitus, COPD and asthma); assess the research infrastructure needed to inform, implement, and evaluate NCD interventions; create a national implementation research agenda for priority NCD; and develop NCD-focused implementation research capacity through short courses, mentored research awards, and an internship placement program.The capacity-building activities are purposely designed around the College of Medicine and the Government of Malawi MOH to ensure sustainability.It was initiated in 2017 and has successfully completed 2 years of operation.
