Introduction: Implementation science (IS) offers methods to systematically achieve the Ending the HIV Epidemic goals in the United States, as well as the global UNAIDS targets. Federal funders such as the National Institutes of Mental Health (NIMH) have invested in implementation research to achieve these goals, including supporting the AIDS Research Centres (ARCs), which focus on high‐impact science in HIV and mental health (MH). To facilitate capacity building for the HIV/MH research workforce in IS, "grey areas," or areas of IS that are confusing, particularly for new investigators, should be addressed in the context of HIV/MH research. Discussion: A group of IS experts affiliated with NIMH‐funded ARCs convened to identify common and challenging grey areas. The group generated a preliminary list of 19 grey areas in HIV/MH‐related IS. From the list, the authors developed a survey which was distributed to all ARCs to prioritize grey areas to address in this paper. ARC members across the United States (N = 60) identified priority grey areas requiring clarification. This commentary discusses topics with 40% or more endorsement. The top grey areas that ARC members identified were: (1) Differentiating implementation strategies from interventions; (2) Determining when an intervention has sufficient evidence for adaptation; (3) Integrating recipient perspectives into HIV/MH implementation research; (4) Evaluating whether an implementation strategy is evidence‐based; (5) Identifying rigorous approaches for evaluating the impact of implementation strategies in the absence of a control group or randomization; and (6) Addressing innovation in HIV/MH IS grants. The commentary addresses each grey area by drawing from the existing literature (when available), providing expert guidance on addressing each in the context of HIV/MH research, and providing domestic and global HIV and HIV/MH case examples that address these grey areas. Conclusions: HIV/MH IS is key to achieving domestic and international goals for ending HIV transmission and mitigating its impact. Guidance offered in this paper can help to overcome challenges to rigorous and high‐impact HIV/MH implementation research. [ABSTRACT FROM AUTHOR]

Human immunodeficiency virus (HIV)‐positive women can breastfeed with minimal risk of mother‐to‐child transmission if taking antiretrovirals. Guidelines surrounding infant feeding for HIV‐positive women have evolved several times over the last two decades. Our review aimed to explore perspectives of breastfeeding with antiretrovirals from HIV‐positive women since the World Health Organization (2010) infant feeding and antiretroviral guidelines. HIV‐positive pregnant and postnatal women from all countries/settings were eligible. HIV‐positive women were either on an antiretroviral regimen at the time of the study, previously on an antiretroviral regimen, not initiated on a regimen yet, or enrolled in prevention of mother‐to‐child transmission (PMTCT) care. Quality assessment of all included studies were conducted. Four databases (CINAHL, EMBASE, MEDLINE and PsycINFO) were searched for studies conducted from January 2010 to October 2020. Nine papers were included in the review, of which two presented findings from the same study. Five analytical themes were developed via thematic synthesis: (1) awareness of breastfeeding with antiretrovirals, (2) turmoil of emotions, (3) coping mechanisms, (4) the intertwining of secret, stigma and support and (5) support needed. Support from family and health care professionals and coping approaches were important to overcome stigma and the emotional challenges of breastfeeding with antiretrovirals. Health care professionals should be familiar with the most updated national and local guidance surrounding infant feeding and antiretrovirals. Further research into interventions to encourage HIV‐positive women to adhere and commit to lifelong antiretroviral treatment (Option B+) for breastfeeding is required. [ABSTRACT FROM AUTHOR]

Introduction: While there is a global consensus on monitoring Human Immunodeficiency Virus (HIV) treatment progress, there has been less attention to the degree of consistency of the measurement of HIV prevention programmes—and the global prevention response is not on‐track to achieve 2020 goals. In this paper, we assess the degree of variability in primary prevention indicators selected by national strategic plans (NSPs) and global stakeholder monitoring and evaluation (M&E) strategies. Methods: We obtained the most recent NSPs from low and middle income Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast‐Track countries, and M&E documents from The Global Fund to Fight AIDS, Tuberculosis and Malaria (The Global Fund), President's Emergency Plan for AIDS Relief (PEPFAR), UNAIDS, the Global HIV Prevention Coalition and the World Health Organization (WHO). We extracted HIV primary prevention indicators from each document, standardized and aggregated them by age/ sex, categorized indicators by topic, and evaluated the frequency of matched indicators between countries and stakeholders. Data were collected between February and April of 2019. Results: Twenty‐one NSPs and five global stakeholder documents were assessed; 736 primary prevention indicators were identified; 284 remained following standardization and aggregation. NSPs contained from 3 to 48 primary prevention indicators, with an average of 23; categories included: HIV education and outreach (17.6%), testing (17.3%) and condom use (16.2%). Of unique national indicators, only 34% was shared between two or more countries. Sixty‐nine per cent was applied in a single country only. 56% of NSP indicators did not appear in any global stakeholder document. Conversely, 42% of global indicators did not appear in any surveyed NSPs. Within global indicators, 63% was only measured by one global body, and no single indicator was measured by all five. Conclusions: These analyses reveal a lack of consensus both between and within countries' and global stakeholders' measurement of HIV prevention. Though some variability is expected, these findings point to a need to refocus attention on achieving greater consensus on a global measurement framework for HIV prevention. [ABSTRACT FROM AUTHOR]

Introduction: In 2004, the US government began to utilize the Food and Drug Administration's (USFDA) tentative approval process (tFDA) as a basis to determine which HIV drugs are appropriate to be purchased and used in resource-constrained settings. This process permits products that are not approved for marketing in the US, including medicines with active patents or marketing restrictions in the US, to be purchased and distributed in resource-constrained settings. Although the tFDA was originally intended to support the United States' President's Emergency Plan for AIDS Relief (PEPFAR), the USFDA list has become a cornerstone of international HIV programmes that support procurement of ARVs, such as the World Health Organization and the Global Fund to Fight AIDS, Tuberculosis, and Malaria. Our objective in this article is to help the global HIV policy makers and implementers of HIV programmes better understand the benefits and limitations of the tFDA by providing an in-depth review of the relevant legal and regulatory processes. Discussion: USFDA's dedicated tFDA process for ARVs used by the PEPFAR programme has a wide impact globally; however, the implementation and the regulatory processes governing the programme have not been thoroughly described in the medical literature. This paper seeks to help stakeholders better understand the legal and regulatory aspects associated with review of ARVs under the tFDA by describing the following: (1) the tFDA and its importance to global ARV procurement; (2) the regulatory pathways for applications under tFDA for the PEPFAR programme, including modifications to applications, review timelines and costs; (3) the role of US patents, US marketing exclusivity rights, and the Medicines Patents Pool in tFDA; and (4) an overview of how applications for PEPFAR programme are processed through the USFDA. We also provide a case study of a new ARV, tenofovir alafenamide fumarate (TAF), not yet reviewed by USFDA for PEPFAR use. Conclusions: In this paper, we describe the importance and implementation of USFDA's tentative approval process to review ARVs for resource-constrained settings. We also highlight the impact of patents and exclusivities on review of HIV drugs under tFDA and illustrate the concepts using a new HIV drug as an example. [ABSTRACT FROM AUTHOR]

Introduction: The transition from paediatric to adult care poses risks to the health of young adults living with HIV if unsuccessful, including interruptions in care and poor health outcomes. Evolving best practices in HIV healthcare transition should ideally be informed by real-world qualitative and quantitative clinical healthcare transition outcomes. There has been a recent proliferation of HIV healthcare transition outcome research, largely from Europe and North America. Methods: A literature search was undertaken using the online databases PubMed, Web of Science, and Google Scholar. Medical subject and text word searches were combined for terms relating to HIV, paediatric transition outcomes, and internal and external factors were used to identify peer-reviewed articles. Results: In this paper, we review data on HIV healthcare transition outcomes in North America and Europe. Internal and external factors which may impact the success of HIV healthcare transition are examined. We describe ongoing research efforts to capture transition outcomes in the North America and Europe. Clinical, operational, and implementation science research gaps that exist to date are highlighted. Efforts to improve HIV healthcare transition research through country-level surveillance networks and large multicentre cohorts, including data integration and linkage between paediatric and adult cohorts are discussed. Conclusions: We identified the need for a comprehensive approach to implementing empirically supported protocols to support healthcare transition for ALHIV. While there is limited prospective longitudinal cohort data available at this time, cohorts linking the paediatric and adolescent with ongoing surveillance into adulthood are being developed. Through a review of existing qualitative and quantitative healthcare transition outcomes studies, we identify emerging areas of consensus surrounding healthcare transition research implementation. Successful healthcare transition programmes in Europe and North America often share several characteristics, including implementation of a youth friendly multidisciplinary approach, consistent communication and integration between paediatric and adult care teams, and an individualized approach which is attuned the adolescent's transition readiness. Moving forward, the voices of youth and young adults living with HIV should be included in the development and evaluation of healthcare transition protocols to ensure that the definition of successful transition reflects all of the stakeholders in the transition process.

Introduction It is increasingly clear that the HIV response will not be sustainable if the number of infections is not significantly reduced. Discussion For two decades, research has been ongoing to identify new behavioural and biomedical strategies to prevent HIV infection. In the past few years, the efficacy of several new strategies has been demonstrated, including oral pre-exposure prophylaxis (PrEP; i.e. daily use of tenofovir/emtricitabine). Because several social, political and logistic barriers remain, however, optimal PrEP implementation will require a better dissemination of new evidence in a number of areas and additional implementation research from various disciplinary perspectives (i.e. social science, policy and ethics; health systems; and economics, including cost-effectiveness studies). Discussion of new evidence on those topics, as well as case studies of potential PrEP implementation in diverse environments, can improve the understanding of the role that PrEP may play in addressing the global HIV/AIDS epidemic. In light of these needs, the Network for Multidisciplinary Studies in ARV-based HIV Prevention (NEMUS) and the World Health Organization (WHO) were honoured to co-organize a special issue of JIAS aimed at contributing to a scholarly discussion of current conditions surrounding PrEP implementation, potential impact and efficiency, social science concerns and the study of PrEP implementation in specific country cases. The papers included in this monograph identify and cover many of the main aspects of the complex yet promising discussions around PrEP implementation today. Conclusions This is a collection of timely contributions from global leaders in HIV research and policy that addresses geographic diversity, uses a trans-disciplinary approach and covers a variety of the complex issues raised by PrEP. As this publication will become accessible to all, we hope that it will remain a valuable resource for policy makers, programme managers, researchers and activists around the world at a moment of a paradigm shift of the global response to HIV.

Introduction The extraordinary feat of proving the effectiveness of oral pre-exposure prophylaxis (PrEP) in clinical trials in different populations in a variety of settings may prove to have been easier than ensuring it is used well. Decision-makers must make difficult choices to realize the promise of antiretroviral prophylaxis for their countries. This paper outlines key economic, regulatory and distributive justice issues that must be addressed for effective and acceptable PrEP implementation. Discussion In considering the role that PrEP can play in combination prevention programmes, decision-makers must determine who can benefit most from PrEP, how PrEP can be provided safely and efficiently, and what kind of health system support will ensure successful implementation. To do this, they need contextualized information on disease burden by population, analyses of how PrEP services might best be delivered, and projections of the human resource and infrastructure requirements for each potential delivery model. There are cost considerations, varying cost-effectiveness results and regulatory challenges. The principles of ethics can inform thorny discussions about who should be prioritized for oral PrEP and how best to introduce it fairly. We describe the cost-effectiveness of PrEP in different populations at higher risk of HIV exposure, its price in low- and middle-income countries, and the current regulatory situation. We explore the principles of ethics that can inform resource allocation decision-making about PrEP anchored in distributive justice, at a time when universal access to antiretroviral treatment remains to be assured. We then highlight the role of advocacy in moving the PrEP agenda forward. Conclusions The time is ripe now for decisions about whether, how and for whom PrEP should be introduced into a country's HIV response. It has the potential to contribute significantly to high impact HIV prevention if it is tailored to those who can most benefit from it and if current regulatory and pricing barriers can be overcome. Advocacy at all levels can help inform decision-making and push the access agenda to avert HIV infections among those at highest risk of HIV exposure. The benefits will accrue beyond the individual level to slow HIV transmission at the population level. [ABSTRACT FROM AUTHOR]

The article discusses research which examined the role of pre-exposure prophylaxis (PrEP) in addressing the global HIV/AIDS epidemic. Topics discussed include the papers on the PrEP implementation, potential impact and efficiency, social science concerns and the study of modern PrEP implementation and cost-effectiveness analysis targeting PrEP and antiretroviral (ART).

Objective To systematically review evidence on the prevalence and risk of disabilities among children and adults living with HIV in sub-Saharan Africa. Methods Articles were identified from 1980 to June 2013 through searching seven electronic databases. Epidemiological studies conducted in sub-Saharan Africa that explored the association between HIV status and general disability or specific impairments, with or without an HIV-uninfected comparison group, were eligible for inclusion. Results Of 12 867 records initially identified, 61 papers were deemed eligible for inclusion. The prevalence of disability was high across age groups, impairment types and study locations. Furthermore, 73% of studies using an HIV- comparator found significantly lower levels of functioning in people living with HIV ( PLHIV). By disability type, the results were as follows: (i) for studies measuring physical impairments ( n = 14), median prevalence of limitations in mobility and motor function among PLHIV was 25.0% (95% CI: 21.8-28.2%). Five of eight comparator studies found significantly reduced functioning among PLHIV; for arthritis, two of three studies which used an HIV- comparison group found significantly increased prevalence among PLHIV; (ii) for sensory impairment studies ( n = 17), median prevalence of visual impairment was 11.2% (95% CI: 9.5-13.1%) and hearing impairment was 24.1% (95% CI: 19.2-29.0%) in PLHIV. Significantly increased prevalence among PLHIV was found in one of four (vision) and three of three studies (hearing) with comparators; (iii) for cognitive impairment in adults ( n = 30), median prevalence for dementia was 25.3% (95% CI: 22.0-28.6%) and 40.9% (95% CI: 37.7-44.1%) for general cognitive impairment. Across all types of cognitive impairment, twelve of fourteen studies found a significant detrimental effect of HIV infection; (iv) for developmental delay in children with HIV ( n = 20), median prevalence of motor delay was 67.7% (95% CI: 62.2-73.2%). All nine studies that included a comparator found a significant difference between PLHIV and controls; for cognitive development and global delay, a significant detrimental effect of HIV was found in five of six and one of two studies, respectively. In the nine cohort studies comparing vertically infected and uninfected children, eight showed a significant gap in development over time in children with HIV. Finally, fifteen of thirty-one (48%) studies found a statistically significant dose-response relationship between indicators of disease progression ( CD4 or WHO stage) and disability. Conclusions HIV is widespread in sub-Saharan Africa and the evidence suggests that it is linked to disabilities, affecting a range of body structures and functions. More research is needed to better understand the implications of HIV-related disability for individuals, their families as well as those working in the fields of disability and HIV so that appropriate interventions can be developed.

Women continue to be at special risk for HIV acquisition due to a complex mix of biological, behavioural, structural, cultural and social factors, with unacceptable rates of new infection. Scientific advances over the past decade have highlighted the use of antiretroviral (ARV) drugs as pre-exposure prophylaxis (PrEP) to prevent HIV acquisition (sexually, parenterally and vertically) and ARV treatment (ART) for HIV-positive patients to prevent onward transmission (treatment as prevention - TasP). This paper reviews the evidence base for PrEP and TasP, describes new products in development and the need to translate research findings into programmes with impact at the population level.

Little attention has been given to understanding the emotional well-being of people living with HIV/AIDS in developing countries, despite the fact that emotions may impact on people's sense of purpose and value, and ultimately their ability and resolve to hold livelihood and familial responsibilities together. Drawing upon research undertaken in the Caprivi Region of Namibia, this paper examines the use of solicited text and photo diaries in enabling insight into the emotional impacts of HIV/AIDS. The advantages and constraints of diary methods are examined, focusing on informant-directed research and the ethical considerations surrounding their use. [ABSTRACT FROM AUTHOR]

Rugby league is the national sport of Papua New Guinea and the game's huge popularity and international profile has been used in recent condom promotion campaigns in the nation's fight against the HIV/AIDS epidemic. In this paper, I argue that the promotion of condom use through rugby league requires a national campaign strategy that includes understandings of condom use and masculinity at the rural level. I demonstrate this through a study of Gogodala men's understandings of the epidemic and condom use in Western Province. The Gogodala are a Christian-based society and many blame the national condom promotion strategy for an increase in promiscuity and for 'turning sex into a game'. Condom availability in this rural area continues to be restricted to a family planning program that promotes Christian values and excludes unmarried men. I explore the male condom dilemma where young men are more concerned with avoiding accusations that their sexual behaviour puts them at risk of contracting HIV despite acknowledging the preventative value of using condoms. In this context young men disassociate themselves from the disease and condom use through a process of calculated risk or risk minimisation. [ABSTRACT FROM AUTHOR]

This paper investigates the extent of knowledge about HIV/AIDS among young Yupno women and men. Local understanding of sikAIDS is shaped by cultural, moral and religious concepts and processes that are based on social values and practices. Difficulties these young people face in accessing information about HIV/AIDS and using it to implement preventative measures -- for example by obtaining condoms -- have to be seen in the framework of 'kastom' and a moral discourse coined and influenced by the Lutheran Church. As the research shows, there is an urgent need for a broad and contextually sensitive approach to sexual health, including information about conception, family planning methods, and sexually transmitted diseases when planning awareness campaigns for teenagers in rural regions.
