RESUMO

Long-term patient engagement and retention in HIV care is an ongoing challenge in South Africa's strained health system. However, some patients thought to be "lost to follow-up" (LTFU) may have "transferred" clinics to receive care elsewhere. Through semi-structured interviews, we explored the relationship between clinic transfer and long-term patient engagement among 19 treatment-experienced people living with HIV (PLWH) who self-identified as having engaged in a clinic transfer at least once since starting antiretroviral therapy (ART) in Gugulethu, Cape Town. Our findings suggest that patient engagement is often fluid, as PLWH cycle in and out of care multiple times during their lifetime. The linear nature of the HIV care cascade model poorly describes the lived realities of PLWH on established treatment. Further research is needed to explore strategies for reducing unplanned clinic transfers and offer more supportive care to new and returning patients.

RESUMO

BACKGROUND: Continuity of care remains a challenge for TB patients who are discharged from hospital and referred to primary health care clinics in South Africa. The aim of this study was to explore the experiences and perceptions of patients, health care workers and family members regarding continuity of TB care in a Cape Town health district. METHODS: We conducted one-on-one interviews, using semi-structured interview guides, with TB patients and their families and health care workers. We also conducted focus group interviews with other health care workers who performed similar duties. Field notes were kept and patients' home circumstances were also physically observed. Data saturation was achieved after 31 interviews. We used Miles and Huberman's qualitative data analysis framework to interpret the data. RESULTS: Themes identified in the interviews were grouped into two categories: (1)  patients' socio-economic circumstances including complex family relationships, good or lack of family support, inadequate income, and agency; and (2) health system challenges, including inadequate referral links between the clinic and the hospital and negative emotions as a result of poor service delivery experienced by patients. CONCLUSION: Some TB Patients experienced poor continuity of care on discharge from hospitals to primary health clinics and perceived that this resulted from socio-economic conditions and health system-related problems that triggered negative emotions. Proper communication between the hospital and clinic regarding patients' care, adequate counselling, and patient-centred treatment are required to address poor continuity of care among patients with TB down-referred to clinics.

RESUMO

BACKGROUND: Many people diagnosed with Mycobacterium tuberculosis (TB) in tertiary and district hospitals in South Africa do not arrive at their primary care clinic for continued care after they are discharged from the hospital. This loss to follow up is a major, ongoing problem for public health in South Africa, and contributes to drug-resistant TB strains. The objective of this paper was to explore patients' experiences and perceptions of diagnosis and treatment before their discharge from hospital. We use a framework known as patient-centred care to illustrate how these patient narratives point to lapses in these principles within the hospital system, and to show how such lapses may contribute to loss to follow up and inconsistent TB care. METHODS: We employed a qualitative study using semi-structured interviews to investigate patient and healthcare workers' experiences and perceptions of TB care in two Western Cape hospitals. We purposefully sampled 17 patients, 10 healthcare workers, and two key informant policy makers, all of whom had relevant experiences and insights. Data collection was done between October 2015 and February 2017. Data were analysed using Miles and Huberman's qualitative analysis framework. RESULTS: Hospitals did not achieve patient-centred care. Newly diagnosed patients were provided with inadequate TB education, diseased-focused approaches were favoured over patient-focused approaches, and there was limited engagement with patients to understand their needs and feelings during the critical period between diagnosis and discharge. Consequently, some patients felt anxious prior to their discharge from hospital. Coupled with their overwhelming socio-economic barriers and complex family situations, some patients felt hopeless and powerless as they prepared for discharge. Finally, there was a lack of patient-provider partnership due to problems including healthcare workers' time constraints and heavy workloads, which detracted from a focus on patients' needs and feelings. CONCLUSIONS: Improving the three intersecting elements of patient-centred care (health education, engaging with patients' needs and feelings, and shared decision-making) has the potential to positively influence patients' continuity of care for TB in South Africa. It would be helpful to also proactively address how patients plan to stay connected to care, on treatment, and supported, in light of their family situation or socio-economic circumstances. Detailed and unique pre-discharge counselling for each patient may be valuable in this regard.

RESUMO

Adolescents living with perinatally acquired HIV are among the first generation in South Africa to grow up with anti-retroviral therapy and democratic freedoms. In this article, we explore the biosocial lives of adolescent boys and young men living with HIV in the Eastern Cape Province of South Africa. We conducted qualitative research with 36 adolescent boys and young men in 2016-2018, including life history narratives, semi-structured interviews, and analysis of health facility files.

RESUMO

For people living with HIV (PLWH), patient transfers may affect engagement in care. We followed a cohort of PLWH in Cape Town, South Africa who tested positive for HIV in 2012-2013 from ART initiation in 2012-2016 through December 2016. Patient transfers were defined as moving from one healthcare facility to another on a different day, considering all healthcare visits and recorded HIV-visits only. We estimated incidence rates (IR) for transfers by time since ART initiation, overall and by gender, and associations between transfers and gaps of > 180 days in clinical care. Overall, 4,176 PLWH were followed for a median of 32 months, and 8% (HIV visits)-17% (all healthcare visits) of visits were patient transfers. Including all healthcare visits, transfers were highest through 3 months on ART (IR 20.2 transfers per 100 visits, 95% CI 19.2-21.2), but increased through 36 months on ART when only HIV visits were included (IR 9.7, 95% CI 8.8-10.8). Overall, women were more likely to transfer than men, and transfers were associated with gaps in care (IR ratio [IRR] 3.06 95% CI 2.83-3.32; HIV visits only). In this cohort, patient transfers were frequent, more common among women, and associated with gaps in care.

RESUMO

BACKGROUND: Childhood vaccination is one of the most effective ways to prevent serious illnesses and deaths in children. However, worldwide, many children do not receive all recommended vaccinations, for several potential reasons. Vaccines might be unavailable, or parents may experience difficulties in accessing vaccination services; for instance, because of poor quality health services, distance from a health facility, or lack of money. Some parents may not accept available vaccines and vaccination services. Our understanding of what influences parents' views and practices around childhood vaccination, and why some parents may not accept vaccines for their children, is still limited. This synthesis links to Cochrane Reviews of the effectiveness of interventions to improve coverage or uptake of childhood vaccination. OBJECTIVES: - Explore parents' and informal caregivers' views and practices regarding routine childhood vaccination, and the factors influencing acceptance, hesitancy, or nonacceptance of routine childhood vaccination. - Develop a conceptual understanding of what and how different factors reduce parental acceptance of routine childhood vaccination. - Explore how the findings of this review can enhance our understanding of the related Cochrane Reviews of intervention effectiveness. SEARCH METHODS: We searched MEDLINE, Embase, CINAHL, and three other databases for eligible studies from 1974 to June 2020. SELECTION CRITERIA: We included studies that: utilised qualitative methods for data collection and analysis; focused on parents' or caregivers' views, practices, acceptance, hesitancy, or refusal of routine vaccination for children aged up to six years; and were from any setting globally where childhood vaccination is provided. DATA COLLECTION AND ANALYSIS: We used a pre-specified sampling frame to sample from eligible studies, aiming to capture studies that were conceptually rich, relevant to the review's phenomenon of interest, from diverse geographical settings, and from a range of income-level settings. We extracted contextual and methodological data from each sampled study. We used a meta-ethnographic approach to analyse and synthesise the evidence. We assessed methodological limitations using a list of criteria used in previous Cochrane Reviews and originally based on the Critical Appraisal Skills Programme quality assessment tool for qualitative studies. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our confidence in each finding. We integrated the findings of this review with those from relevant Cochrane Reviews of intervention effectiveness. We did this by mapping whether the underlying theories or components of trial interventions included in those reviews related to or targeted the overarching factors influencing parental views and practices regarding routine childhood vaccination identified by this review. MAIN RESULTS: We included 145 studies in the review and sampled 27 of these for our analysis. Six studies were conducted in Africa, seven in the Americas, four in South-East Asia, nine in Europe, and one in the Western Pacific. Studies included urban and rural settings, and high-, middle-, and low-income settings. Many complex factors were found to influence parents' vaccination views and practices, which we divided into four themes. Firstly, parents' vaccination ideas and practices may be influenced by their broader ideas and practices surrounding health and illness generally, and specifically with regards to their children, and their perceptions of the role of vaccination within this context. Secondly, many parents' vaccination ideas and practices were influenced by the vaccination ideas and practices of the people they mix with socially. At the same time, shared vaccination ideas and practices helped some parents establish social relationships, which in turn strengthened their views and practices around vaccination. Thirdly, parents' vaccination ideas and practices may be influenced by wider political issues and concerns, and particularly their trust (or distrust) in those associated with vaccination programmes. Finally, parents' vaccination ideas and practices may be influenced by their access to and experiences of vaccination services and their frontline healthcare workers. We developed two concepts for understanding possible pathways to reduced acceptance of childhood vaccination. The first concept, 'neoliberal logic', suggests that many parents, particularly from high-income countries, understood health and healthcare decisions as matters of individual risk, choice, and responsibility. Some parents experienced this understanding as in conflict with vaccination programmes, which emphasise generalised risk and population health. This perceived conflict led some parents to be less accepting of vaccination for their children. The second concept, 'social exclusion', suggests that some parents, particularly from low- and middle-income countries, were less accepting of childhood vaccination due to their experiences of social exclusion. Social exclusion may damage trustful relationships between government and the public, generate feelings of isolation and resentment, and give rise to demotivation in the face of public services that are poor quality and difficult to access. These factors in turn led some parents who were socially excluded to distrust vaccination, to refuse vaccination as a form of resistance or a way to bring about change, or to avoid vaccination due to the time, costs, and distress it creates. Many of the overarching factors our review identified as influencing parents' vaccination views and practices were underrepresented in the interventions tested in the four related Cochrane Reviews of intervention effectiveness. AUTHORS' CONCLUSIONS: Our review has revealed that parents' views and practices regarding childhood vaccination are complex and dynamic social processes that reflect multiple webs of influence, meaning, and logic. We have provided a theorised understanding of the social processes contributing to vaccination acceptance (or not), thereby complementing but also extending more individualistic models of vaccination acceptance. Successful development of interventions to promote acceptance and uptake of childhood vaccination will require an understanding of, and then tailoring to, the specific factors influencing vaccination views and practices of the group(s) in the target setting. The themes and concepts developed through our review could serve as a basis for gaining this understanding, and subsequent development of interventions that are potentially more aligned with the norms, expectations, and concerns of target users.

RESUMO

BACKGROUND: This is the eighth in our series of 11 papers on "CHWs at the Dawn of a New Era". Community health worker (CHW) incentives and remuneration are core issues that affect the performance of individual CHWs and the performance of the overall CHW programme. A better understanding of what motivates CHWs and a stronger awareness of the social justice dimensions of remuneration are essential in order to build stronger CHW programmes and to support the professionalization of the CHW workforce. METHODS: We provide examples of incentives that have been provided to CHWs and identify factors that motivate and demotivate CHWs. We developed our findings in this paper by synthesizing the findings of a recent review of CHW motivation and incentives in a wide variety of CHW programmes with detailed case study data about CHW compensation and incentives in 29 national CHW programmes. RESULTS: Incentives can be direct or indirect, and they can be complementary/demand-side incentives. Direct incentives can be financial or nonfinancial. Indirect incentives can be available through the health system or from the community, as can complementary, demand-side incentives. Motivation is sustained when CHWs feel they are a valued member of the health system and have a clear role and set of responsibilities within it. A sense of the "do-ability" of the CHW role is critical in maintaining CHW motivation. CHWs are best motivated by work that provides opportunities for personal growth and professional development, irrespective of the direct remuneration and technical skills obtained. Working and social relationships among CHWs themselves and between CHWs and other healthcare professionals and community members strongly shape CHW motivation. CONCLUSION: Our findings support the recent guidelines for CHWs released by WHO in 2018 that call for CHWs to receive a financial package that corresponds to their job demands, complexity, number of hours worked, training, and the roles they undertake. The guidelines also call for written agreements that specify the CHW's role and responsibilities, working conditions, remuneration, and workers' rights.

RESUMO

BACKGROUND: Data harmonisation (DH) has emerged amongst health managers, information technology specialists and researchers as an important intervention for routine health information systems (RHISs). It is important to understand what DH is, how it is defined and conceptualised, and how it can lead to better health management decision-making. This scoping review identifies a range of definitions for DH, its characteristics (in terms of key components and processes), and common explanations of the relationship between DH and health management decision-making. METHODS: This scoping review identified relevant studies from 2000 onwards (date filter), written in English and published in PubMed, Web of Science and CINAHL. Two reviewers independently screened records for potential inclusion for the abstract and full-text screening stages. One reviewer did the data extraction, analysis and synthesis, with built-in reliability checks from the rest of the team. We developed a narrative synthesis of definitions and explanations of the relationship between DH and health management decision-making. RESULTS: We sampled 61 of 181 included to synthesis definitions and concepts of DH in detail. We identified six common terms for data harmonisation: record linkage, data linkage, data warehousing, data sharing, data interoperability and health information exchange. We also identified nine key components of data harmonisation: DH involves (a) a process of multiple steps; (b) integrating, harmonising and bringing together different databases (c) two or more databases; (d) electronic data; (e) pooling data using unique patient identifiers; and (f) different types of data; (g) data found within and across different departments and institutions at facility, district, regional and national levels; (h) different types of technical activities; (i) has a specific scope. The relationship between DH and health management decision-making is not well-described in the literature. Several studies mentioned health providers' concerns about data completeness, data quality, terminology and coding of data elements as barriers to data utilisation for clinical decision-making. CONCLUSION: To our knowledge, this scoping review was the first to synthesise definitions and concepts of DH and address the causal relationship between DH and health management decision-making. Future research is required to assess the effectiveness of data harmonisation on health management decision-making.

RESUMO

The Mycobacterium tuberculosis (Mtb) DosRST two-component regulatory system promotes the survival of Mtb during non-replicating persistence (NRP). NRP bacteria help drive the long course of tuberculosis therapy; therefore, chemical inhibition of DosRST may inhibit the ability of Mtb to establish persistence and thus shorten treatment. Using a DosRST-dependent fluorescent Mtb reporter strain, a whole-cell phenotypic high-throughput screen of a ∼540,000 compound small-molecule library was conducted. The screen discovered novel inhibitors of the DosRST regulon, including three compounds that were subject to follow-up studies: artemisinin, HC102A and HC103A. Under hypoxia, all three compounds inhibit Mtb-persistence-associated physiological processes, including triacylglycerol synthesis, survival and antibiotic tolerance. Artemisinin functions by disabling the heme-based DosS and DosT sensor kinases by oxidizing ferrous heme and generating heme-artemisinin adducts. In contrast, HC103A inhibits DosS and DosT autophosphorylation activity without targeting the sensor kinase heme.

RESUMO

BACKGROUND: Having nurses take on tasks that are typically conducted by doctors (doctor-nurse substitution, a form of 'task-shifting') may help to address doctor shortages and reduce doctors' workload and human resource costs. A Cochrane Review of effectiveness studies suggested that nurse-led care probably leads to similar healthcare outcomes as care delivered by doctors. This finding highlights the need to explore the factors that affect the implementation of strategies to substitute doctors with nurses in primary care. In our qualitative evidence synthesis (QES), we focused on studies of nurses taking on tasks that are typically conducted by doctors working in primary care, including substituting doctors with nurses or expanding nurses' roles. OBJECTIVES: (1) To identify factors influencing implementation of interventions to substitute doctors with nurses in primary care. (2) To explore how our synthesis findings related to, and helped to explain, the findings of the Cochrane intervention review of the effectiveness of substituting doctors with nurses. (3) To identify hypotheses for subgroup analyses for future updates of the Cochrane intervention review. SEARCH METHODS: We searched CINAHL and PubMed, contacted experts in the field, scanned the reference lists of relevant studies and conducted forward citation searches for key articles in the Social Science Citation Index and Science Citation Index databases, and 'related article' searches in PubMed. SELECTION CRITERIA: We constructed a maximum variation sample (exploring variables such as country level of development, aspects of care covered and the types of participants) from studies that had collected and analysed qualitative data related to the factors influencing implementation of doctor-nurse substitution and the expansion of nurses' tasks in community or primary care worldwide. We included perspectives of doctors, nurses, patients and their families/carers, policymakers, programme managers, other health workers and any others directly involved in or affected by the substitution. We excluded studies that collected data using qualitative methods but did not analyse the data qualitatively. DATA COLLECTION AND ANALYSIS: We identified factors influencing implementation of doctor-nurse substitution strategies using a framework thematic synthesis approach. Two review authors independently assessed the methodological strengths and limitations of included studies using a modified Critical Appraisal Skills Programme (CASP) tool. We assessed confidence in the evidence for the QES findings using the GRADE-CERQual approach. We integrated our findings with the evidence from the effectiveness review of doctor-nurse substitution using a matrix model. Finally, we identified hypotheses for subgroup analyses for updates of the review of effectiveness. MAIN RESULTS: We included 66 studies (69 papers), 11 from low- or middle-income countries and 55 from high-income countries. These studies found several factors that appeared to influence the implementation of doctor-nurse substitution strategies. The following factors were based on findings that we assessed as moderate or high confidence.Patients in many studies knew little about nurses' roles and the difference between nurse-led and doctor-led care. They also had mixed views about the type of tasks that nurses should deliver. They preferred doctors when the tasks were more 'medical' but accepted nurses for preventive care and follow-ups. Doctors in most studies also preferred that nurses performed only 'non-medical' tasks. Nurses were comfortable with, and believed they were competent to deliver a wide range of tasks, but particularly emphasised tasks that were more health promotive/preventive in nature.Patients in most studies thought that nurses were more easily accessible than doctors. Doctors and nurses also saw nurse-doctor substitution and collaboration as a way of increasing people's access to care, and improving the quality and continuity of care.Nurses thought that close doctor-nurse relationships and doctor's trust in and acceptance of nurses was important for shaping their roles. But nurses working alone sometimes found it difficult to communicate with doctors.Nurses felt they had gained new skills when taking on new tasks. But nurses wanted more and better training. They thought this would increase their skills, job satisfaction and motivation, and would make them more independent.Nurses taking on doctors' tasks saw this as an opportunity to develop personally, to gain more respect and to improve the quality of care they could offer to patients. Better working conditions and financial incentives also motivated nurses to take on new tasks. Doctors valued collaborating with nurses when this reduced their own workload.Doctors and nurses pointed to the importance of having access to resources, such as enough staff, equipment and supplies; good referral systems; experienced leaders; clear roles; and adequate training and supervision. But they often had problems with these issues. They also pointed to the huge number of documents they needed to complete when tasks were moved from doctors to nurses. AUTHORS' CONCLUSIONS: Patients, doctors and nurses may accept the use of nurses to deliver services that are usually delivered by doctors. But this is likely to depend on the type of services. Nurses taking on extra tasks want respect and collaboration from doctors; as well as proper resources; good referral systems; experienced leaders; clear roles; and adequate incentives, training and supervision. However, these needs are not always met.

RESUMO

BACKGROUND: In recent decades there have been great improvements in the reproductive health of women in low- and middle-income countries and increases in the use of modern contraceptive methods. Nonetheless, many women are not able to access information, contraceptive technologies and services that could facilitate preventing unintended pregnancies and planning the number and timing of desired pregnancies. In South Africa, the contraceptive prevalence rate is 64.6%. However, this relatively high contraceptive prevalence rate masks problems with quality contraceptive service delivery, equitable access, and women's ability to correctly and consistently, use contraceptive methods of their choice. This study set out to understand the specific family planning and contraceptive needs and behaviours of women of reproductive age in South Africa, through a lived experience, multisensory approach. METHODS: Participatory qualitative research methods were used including body mapping workshops amongst reproductive aged women recruited from urban and peri urban areas in the Western Cape South Africa. Data including body map images were analysed using a thematic analysis approach. RESULTS: Women had limited biomedical knowledge of the female reproductive anatomy, conception, fertility and how contraceptives worked, compounded by a lack of contraceptive counseling and support from health care providers. Women's preferences for different contraceptive methods were not based on a single, sensory or experiential factor. Rather, they were made up of a composite of sensory, physical, social and emotional experiences underscored by potential for threats to bodily harm. CONCLUSIONS: This study highlighted the need to address communication and knowledge gaps around the female reproductive anatomy, different contraceptive methods and how contraception works to prevent a pregnancy. Women, including younger women, identified sexual and reproductive health knowledge gaps themselves and identified these gaps as important factors that influenced uptake and effective contraceptive use. These knowledge gaps were overwhelmingly linked to poor or absent communication and counseling provided by health care providers. Body mapping techniques could be used in education and communication strategies around sexual and reproductive health programmes in diverse settings.

RESUMO

BACKGROUND: The rollout of universal, lifelong treatment for all HIV-positive pregnant and breastfeeding women ("Option B+") has rapidly increased the number of women initiating antiretroviral treatment (ART) and requiring ART care postpartum. In a pilot project in South Africa, eligible postpartum women were offered the choice of referral to the standard of care, a local primary health care clinic, or a community-based model of differentiated ART services, the adherence club (AC). ACs have typically enrolled only non-pregnant and non-postpartum adults; postpartum women had not previously been referred directly from antenatal care. There is little evidence regarding postpartum women's preferences for and experiences of differentiated models of care, or the capacity of this particular model to cater to their specific needs. This qualitative paper reports on feedback from both postpartum women and health workers who care for them on their respective experiences of the AC. METHODS: One-on-one in-depth qualitative interviews were conducted with 19 (23%) of the 84 postpartum women who selected the AC and were retained at approximately 12 months postpartum, and 9 health workers who staff the AC. Data were transcribed and thematically analysed using NVivo 11. RESULTS: Postpartum women's inclusion in the AC was acceptable for both participants and health workers. Health workers were welcoming of postpartum women but expressed concerns about prospects for longer term adherence and retention, and raised logistical issues they felt might compromise trust with AC members in general. CONCLUSIONS: Enrolling postpartum women in mixed groups with the general adult population is feasible and acceptable. Preliminary recommendations are offered and may assist in supporting the specific needs of postpartum women transitioning from antenatal ART care.

RESUMO

We investigated condom and lubricant use, rectal cleansing and rectal gel use for penile-anal intercourse (PAI), during in-depth interviews with women from South Africa, Uganda and Zimbabwe who formerly participated in VOICE, a five-arm HIV prevention trial of two antiretroviral tablets and a vaginal gel. Few studies have addressed practices related to PAI among women; existing data from Africa on condom and lubricant use for PAI, as well as preparatory practices of PAI such as rectal cleansing, are limited to men who have sex with men. Women demonstrated a lack of awareness of HIV transmission risks of PAI and none of the participants reported using condom-compatible lubricants for PAI. Participants described a variety of preparatory rectal cleansing practices. Some participants disclosed rectal use of the vaginal study gel. Understanding practices related to PAI in Africa is critical to microbicide development, as these practices are likely to influence the acceptability, feasibility, and use of both vaginal and rectal microbicide products.

RESUMO

Medical abortion is a method of pregnancy termination that by its nature enables more active involvement of women in the process of managing, and sometimes even administering the medications for, their abortions. This qualitative evidence synthesis reviewed the global evidence on experiences with, preferences for, and concerns about greater self-management of medical abortion with lesser health professional involvement. We focused on qualitative research from multiple perspectives on women's experiences of self-management of first trimester medical abortion (<12weeks gestation). We included research from both legal and legally-restricted contexts whether medical abortion was accessed through formal or informal systems. A review team of four identified 36 studies meeting inclusion criteria, extracted data from these studies, and synthesized review findings. Review findings were organized under the following themes: general perceptions of self-management, preparation for self-management, logistical considerations, issues of choice and control, and meaning and experience. The synthesis highlights that the qualitative evidence base is still small, but that the available evidence points to the overall acceptability of self-administration of medical abortion. We highlight particular considerations when offering self-management options, and identify key areas for future research. Further qualitative research is needed to strengthen this important evidence base.

RESUMO

BACKGROUND: The ethical concerns associated with HIV prevention and treatment research have been widely explored in South Africa over the past 3 decades. However, HIV cure research is relatively new to the region and significant ethical and social challenges are anticipated. There has been no published empirical enquiry in Africa into key informant perspectives on HIV cure research. Consequently, this study was conducted to gain preliminary data from South African HIV clinicians, researchers and activists. METHODS: In-depth interviews were conducted on a purposive sample of fourteen key informants in South Africa. Audiotaped interviews were transcribed verbatim with concurrent thematic analysis. The perspectives of HIV clinicians, researchers and activists were captured. Analyst triangulation occurred as the data were analysed by three authors independently. RESULTS: The rapid evolution of HIV cure research agendas was prominent with participants expressing some concern that the global North was driving the cure agenda. Participants described a symbiotic relationship between cure, treatment and prevention research necessitating collaboration. Assessing and managing knowledge and expectations around HIV cure research emerged as a central theme related to challenges to constructing 'cure' - how patients understand the idea of cure is important in explaining the complexity of cure research especially in the South African context where understanding of science is often challenging. Managing expectations and avoiding curative misconception will have implications for consent processes. Unique strategies in cure research could include treatment interruption, which has the potential to create therapeutic and ethical conflict and will be perceived as a significant risk. Ethical challenges in cure research will impact on informed consent and community engagement. CONCLUSIONS: It was encouraging to note the desire for synergy amongst researchers and clinicians working in the fields of prevention, treatment and cure. Translation of complex HIV cure science into lay language is critical. Moving forward, RECs must be adequately constituted with scientific expertise and community representation when reviewing cure protocols. It is hoped that knowledge and resource sharing in the context of collaboration between research scientists working in cure and those working in treatment and prevention will accelerate progress towards cure.

RESUMO

Sexual risk-taking is influenced by individual, interpersonal and social factors. This paper presents findings from a qualitative follow-up study to a clinical trial evaluating biomedical HIV prevention products among African women, explored participants' perceptions and experiences of heterosexual penile-anal intercourse, as well as the gendered power dynamics and relationship contexts in which this sexual behaviour occurs. In-depth interviews were conducted with 88 women from South Africa, Uganda and Zimbabwe. Findings reveal that despite its social stigmatisation, women engage in penile-anal intercourse for reasons including male pleasure, relationship security, hiding infidelity, menstruation, vaginal infections, money and beliefs that it will prevent HIV transmission. In addition, participants described experiences of non-consensual penile-anal intercourse. We used sexual scripting theory as an analytical framework with which to describe the sociocultural and relationship contexts and gendered power dynamics in which these practices occur. These data on the distinct individual, dyadic and social contexts of heterosexual penile-anal intercourse, and the specific factors that may contribute to women's HIV risk, make a unique contribution to our understanding of heterosexual behaviour in these sub-Saharan countries, thereby helping to inform both current and future HIV prevention efforts for women in the region.

RESUMO

Mycobacterium tuberculosis must sense and adapt to host environmental cues to establish and maintain an infection. The two-component regulatory system PhoPR plays a central role in sensing and responding to acidic pH within the macrophage and is required for M. tuberculosis intracellular replication and growth in vivo. Therefore, the isolation of compounds that inhibit PhoPR-dependent adaptation may identify new antivirulence therapies to treat tuberculosis. Here, we report that the carbonic anhydrase inhibitor ethoxzolamide inhibits the PhoPR regulon and reduces pathogen virulence. We show that treatment of M. tuberculosis with ethoxzolamide recapitulates phoPR mutant phenotypes, including downregulation of the core PhoPR regulon, altered accumulation of virulence-associated lipids, and inhibition of Esx-1 protein secretion. Quantitative single-cell imaging of a PhoPR-dependent fluorescent reporter strain demonstrates that ethoxzolamide inhibits PhoPR-regulated genes in infected macrophages and mouse lungs. Moreover, ethoxzolamide reduces M. tuberculosis growth in both macrophages and infected mice. Ethoxzolamide inhibits M. tuberculosis carbonic anhydrase activity, supporting a previously unrecognized link between carbonic anhydrase activity and PhoPR signaling. We propose that ethoxzolamide may be pursued as a new class of antivirulence therapy that functions by modulating expression of the PhoPR regulon and Esx-1-dependent virulence.

RESUMO

Young women in southern Africa experience some of the highest incidence rates of HIV infection in the world. Across southern Africa, HIV prevalence among women increases rapidly between the teenage years and young adulthood. Adult HIV prevalence is 16.8 % in South Africa, 23 % in Botswana, 23 % in Lesotho, and 26.5 % in Swaziland. Existing research has illuminated some of the key social, behavioral, and structural factors associated with young women's disproportionate HIV risk, including gendered social norms that advantage male power in sexual relationships and age disparities in relationships between younger women and older male partners. Important structural factors include the region's history of labor migration and legacy of family disruption, and entrenched social and economic inequalities. New interventions are emerging to address these high levels of HIV risk in the key population of young women, including structural interventions, biomedical prevention such as PrEP, and combined HIV prevention approaches.

RESUMO

Since the 1994 International Conference on Population and Development, researchers and practitioners have engaged in a series of efforts to shift health programming with men from being gender-neutral to being more gender-sensitive and gender-transformative. Efforts in this latter category have been increasingly utilised, particularly in the last decade, and attempt to transform gender relations to be more equitable in the name of improved health outcomes for both women and men. We begin by assessing the conceptual progression of social science contributions to gender-transformative health programming with men. Next, we briefly assess the empirical evidence from gender-transformative health interventions with men. Finally, we examine some of the challenges and limitations of gender-transformative health programmes and make recommendations for future work in this thriving interdisciplinary area of study.
