Uptake, accuracy, safety and linkage into care over two years of promoting annual self-testing for HIV in Blantyre, Malawi: a community-based prospective study

A set of anonymised datasets produced in a community-based study to investigate self-testing for HIV in Blantyre, Malawi. Taken together the datasets enable replication of findings from the study including estimation of uptake of HIV self-testing (HIVST), analysis of sensitivity/specificity of self-reported self-test results compared to nurse-performed finger prick testing, and investigation of self-reported coercion to self-test

'For a mere cough, men must just chew Conjex, gain strength, and continue working': the provider construction and tuberculosis care-seeking implications in Blantyre, Malawi.

BACKGROUND: Delay by men in seeking healthcare results in their higher mortality while on HIV or tuberculosis (TB) treatment and contributes to ongoing community-level disease transmission before going on treatment. OBJECTIVE: To understand masculinity's role in delay in healthcare seeking for men, with a focus on TB-suggestive symptoms. DESIGN: Data were collected between March 2011 and March 2012 in low-income suburbs in urban Blantyre using focus group discussions with community members (n=8) and health workers (n=2), in-depth interviews with 20 TB patients (female=14) and 20 uninvestigated chronic coughers (female=8), and a 3-day participatory workshop with 27 health stakeholder representatives. The research process drew to a large extent on grounded theory principles in the manner of Strauss and Corbin (1998) and also Charmaz (1995). RESULTS: Role descriptions by both men and women in the study universally assigned men as primary material providers for their immediate family, that is, the ones earning and bringing livelihood and additional material needs. In a context where collectivism was valued, men were also expected to lead the provision of support to wider kin. Successful role enactment was considered key to achieving recognition as an adequate man; at the same time, job scarcity and insecurity, and low earnings gravely impeded men. Pressures to generate continuing income then meant constantly looking for jobs, or working continuously to retain insecure jobs or to raise money through self-employment. All this led men to relegate their health considerations. CONCLUSIONS: Early engagement with formal healthcare is critical to dealing with TB and HIV. However, role constructions as portrayed for men in this study, along with the opportunity costs of acknowledging illness seem, in conditions of vulnerability, important barriers to care-seeking. There is a need to address hidden care-seeking costs and to consider more complex interventions, including reducing precarity, in efforts to improve men's engagement with their health

Control, struggle, and emergent masculinities: a qualitative study of men's care-seeking determinants for chronic cough and tuberculosis symptoms in Blantyre, Malawi.

BACKGROUND: Men's healthcare-seeking delay results in higher mortality while on HIV or tuberculosis (TB) treatment, and implies contribution to ongoing community-level TB transmission before initiating treatment. We investigated masculinity's role in healthcare-seeking delay for men with TB-suggestive symptoms, with a view to developing potential interventions for men. METHODS: Data were collected during March 2011- March 2012 in three high-density suburbs in urban Blantyre. Ten focus group discussions were carried out of which eight (mixed sex = two; female only = three; male only = three) were with 74 ordinary community members, and two (both mixed sex) were with 20 health workers. Individual interviews were done with 20 TB patients (female =14) and 20 un-investigated chronic coughers (female = eight), and a three-day workshop was held with 27 health stakeholder representatives. RESULTS: An expectation to provide for and lead their families, and to control various aspects of their lives while facing limited employment opportunities and small incomes leaves men feeling inadequate, devoid of control, and anxious about being marginalised as men. Men were fearful about being looked at as less than men, and about their wives engaging in extramarital sex without ability to detect or monitor them. Control was a key defining feature of adequate manhood, and efforts to achieve it also led men into side-lining their health. Articulate and consistent concepts of men's bodily strength or appropriate illness responses were absent from the accounts. CONCLUSIONS: Facilitating men to seek care early is an urgent public health imperative, given the contexts of high HIV/AIDS prevalence but increasingly available treatment, and the role of care-seeking delay in TB transmission. Men's struggles trying to achieve ideal images seem to influence their engagement with their health. Ambiguous views regarding some key masculinity representations and the embrace of less harmful masculinities raise questions about some common assumptions that guide work with men. Apparent 'emergent masculinities' might be a useful platform from which to support the transformation of harmful masculinity. Finally, the complex manifestations of masculinity indicate the need for interventions targeting men in health and TB control to assume supportive, multidimensional and long-term outlooks

Factors shaping initial decision-making to self-test amongst cohabiting couples in urban Blantyre, Malawi.

In sub-Saharan Africa, most new HIV infections occur in stable relationships, making couples testing an important intervention for HIV prevention. We explored factors shaping the decision-making of cohabiting couples who opted to self-test in Blantyre, Malawi. Thirty-four self-tested participants (17 couples) were interviewed. Motivators for HIV self-testing (HIVST) emerged at three main levels. Individual motivations included perceived benefits of access to treatment, and self-checking of serostatus in the hope of having been cured by prolonged treatment or faith-healing. HIVST was considered convenient, confidential, reassuring and an enabling new way to test with one's partner. Partnership motivations included both positive (mutual encouragement) and negative (suspected infidelity) aspects. For women, long-term health and togetherness were important goals that reinforced motivations for couples testing, whereas men often needed persuasion despite finding HIVST more flexible and less onerous than facility-based testing. Internal conflict prompted some partners to use HIVST as a way of disclosing their previously concealed HIV positive serostatus. Thus, the implementation of community-based HIVST should acknowledge and appropriately respond to decision-making processes within couples, which are shaped by gender roles and relationship dynamics

HIV self-testing services for female sex workers, Malawi and Zimbabwe

OBJECTIVE: To present findings from implementation and scale-up of human immunodeficiency virus (HIV) self-testing programmes for female sex workers in Malawi and Zimbabwe, 2013-2018. METHODS: In Zimbabwe, we carried out formative research to assess the acceptability and accuracy of HIV self-testing. During implementation we evaluated sex workers' preferences for, and feasibility of, distribution of test kits before the programme was scaled-up. In Malawi, we conducted a rapid ethnographic assessment to explore the context and needs of female sex workers and resources available, leading to a workshop to define the distribution approach for test kits. Once distribution was implemented, we conducted a process evaluation and established a system for monitoring social harm. FINDINGS: In Zimbabwe, female sex workers were able to accurately self-test. The preference study helped to refine systems for national scale-up through existing services for female sex workers. The qualitative data helped to identify additional distribution strategies and mediate potential social harm to women. In Malawi, peer distribution of test kits was the preferred strategy. We identified some incidents of social harm among peer distributors and female sex workers, as well as supply-side barriers to implementation which hindered uptake of testing. CONCLUSION: Involving female sex workers in planning and ongoing implementation of HIV self-testing is essential, along with strategies to mitigate potential harm. Optimal strategies for distribution and post-test support are context-specific and need to consider existing support for female sex workers and levels of trust and cohesion within their communities

Cluster randomised controlled trial to determine the effect of peer delivery HIV self-testing to support linkage to HIV prevention among young women in rural KwaZulu-Natal, South Africa: a study protocol.

INTRODUCTION: A cluster randomised controlled trial (cRCT) to determine whether HIV self-testing (HIVST) delivered by peers either directly or through incentivised peer-networks, could increase the uptake of antiretroviral therapy and pre-exposure prophylaxis (PrEP) among young women (18 to 24 years) is being undertaken in an HIV hyperendemic area in KwaZulu-Natal, South Africa. METHODS AND ANALYSIS: A three-arm cRCT started mid-March 2019, in 24 areas in rural KwaZulu-Natal. Twenty-four pairs of peer navigators working with ~12 000 young people aged 18 to 30 years over a period of 6 months were randomised to: (1) incentivised-peer-networks: peer-navigators recruited participants 'seeds' to distribute up to five HIVST packs and HIV prevention information to peers within their social networks. Seeds receive an incentive (20 Rand = US$1.5) for each respondent who contacts a peer-navigator for additional HIVST packs to distribute; (2) peer-navigator-distribution: peer-navigators distribute HIVST packs and information directly to young people; (3) standard of care: peer-navigators distribute referral slips and information. All arms promote sexual health information and provide barcoded clinic referral slips to facilitate linkage to HIV testing, prevention and care services. The primary outcome is the difference in linkage rate between arms, defined as the number of women (18 to 24 years) per peer-navigators month of outreach work (/pnm) who linked to clinic-based PrEP eligibility screening or started antiretroviral, based on HIV-status, within 90 days of receiving the clinic referral slip. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Boards at the WHO, Switzerland (Protocol ID: STAR CRT, South Africa), London School of Hygiene and Tropical Medicine, UK (Reference: 15 990-1), University of KwaZulu-Natal (BFC311/18) and the KwaZulu-Natal Department of Health (Reference: KZ_201901_012), South Africa. The findings of this trial will be disseminated at local, regional and international meetings and through peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT03751826; Pre-results

Understanding acceptability of and engagement with web-based interventions aiming to improve quality of life in cancer survivors: A synthesis of current research

Purpose. This review sought to summarize existing knowledge in order to inform the development of an online intervention that aims to improve quality of life after cancer treatment. Methods. To inform our intervention, we searched for studies relating to web-based interventions designed to improve QoL in adults who have completed primary treatment for breast, prostate and colorectal cancer (as these are three of the most common cancers and impact a large number of cancer survivors). We included a variety of study designs (qualitative research, feasibility/pilot trials, randomised trials, and process evaluations) and extracted all available information regarding intervention characteristics, experiences, and outcomes. Data were synthesised as textual (qualitative) data and analysed using thematic analysis. Results. Fifty-seven full text articles were assessed for eligibility and 16 papers describing nine interventions were analysed. Our findings suggest that cancer survivors value interventions that offer content specific to their changing needs and are delivered at the right stage of the cancer trajectory. Social networking features do not always provide added benefit, and behaviour change techniques need to be implemented carefully to avoid potential negative consequences for some users. Conclusions. Future work should aim to identify appropriate strategies for promoting health behaviour change, as well as the optimal stage of cancer survivorship to facilitate intervention delivery. Clinical Implications. The development of web-based interventions for cancer survivors requires further exploration to better understand how interventions can be carefully designed to match this group’s unique needs and capabilities. User involvement during development may help to ensure that interventions are accessible, perceived as useful, and appropriate for challenges faced at different stages of the cancer survivorship trajectory

A budding yeast model for human disease mutations in the EXOSC2 cap subunit of the RNA exosome complex

RNA exosomopathies, a growing family of diseases, are linked to missense mutations in genes encoding structural subunits of the evolutionarily conserved, 10-subunit exoribonuclease complex, the RNA exosome. This complex consists of a three-subunit cap, a six-subunit, barrel-shaped core, and a catalytic base subunit. While a number of mutations in RNA exosome genes cause pontocerebellar hypoplasia, mutations in the cap subunit gene EXOSC2 cause an apparently distinct clinical presentation that has been defined as a novel syndrome SHRF (short stature, hearing loss, retinitis pigmentosa, and distinctive facies). We generated the first in vivo model of the SHRF pathogenic amino acid substitutions using budding yeast by modeling pathogenic EXOSC2 missense mutations (p.Gly30Val and p.Gly198Asp) in the orthologous S. cerevisiae gene RRP4 The resulting rrp4 mutant cells show defects in cell growth and RNA exosome function. Consistent with altered RNA exosome function, we detect significant transcriptomic changes in both coding and noncoding RNAs in rrp4-G226D cells that model EXOSC2 p.Gly198Asp, suggesting defects in nuclear surveillance. Biochemical and genetic analyses suggest that the Rrp4 G226D variant subunit shows impaired interactions with key RNA exosome cofactors that modulate the function of the complex. These results provide the first in vivo evidence that pathogenic missense mutations present in EXOSC2 impair the function of the RNA exosome. This study also sets the stage to compare exosomopathy models to understand how defects in RNA exosome function underlie distinct pathologies

Process evaluation of peer-to-peer delivery of HIV self-testing and sexual health information to support HIV prevention among youth in rural KwaZulu-Natal, South Africa: qualitative analysis

OBJECTIVE: Peer-to-peer (PTP) HIV self-testing (HIVST) distribution models can increase uptake of HIV testing and potentially create demand for HIV treatment and pre-exposure prophylaxis (PrEP). We describe the acceptability and experiences of young women and men participating in a cluster randomised trial of PTP HIVST distribution and antiretroviral/PrEP promotion in rural KwaZulu-Natal. METHODS: Between March and September 2019, 24 pairs of trained peer navigators were randomised to two approaches to distribute HIVST packs (kits+HIV prevention information): incentivised-peer-networks where peer-age friends distributed packs within their social network for a small incentive, or direct distribution where peer navigators distributed HIVST packs directly. Standard-of-care peer navigators distributed information without HIVST kits. For the process evaluation, we conducted semi-structured interviews with purposively sampled young women (n=30) and men (n=15) aged 18-29 years from all arms. Qualitative data were transcribed, translated, coded manually and thematically analysed using an interpretivist approach. RESULTS: Overall, PTP approaches were acceptable and valued by young people. Participants were comfortable sharing sexual health issues they would not share with adults. Coupled with HIVST, peer (friends) support facilitated HIV testing and solidarity for HIV status disclosure and treatment. However, some young people showed limited interest in other sexual health information provided. Some young people were wary of receiving health information from friends perceived as non-professionals while others avoided sharing personal issues with peer navigators from their community. Referral slips and youth-friendly clinics were facilitators to PrEP uptake. Family disapproval, limited information, daily pills and perceived risks were major barriers to PrEP uptake. CONCLUSION: Both professional (peer navigators) and social network (friends) approaches were acceptable methods to receive HIVST and sexual health information. Doubts about the professionalism of friends and overly exclusive focus on HIVST information materials may in part explain why HIVST kits, without peer navigators support, did not create demand for PrEP
