Objectives Broad international guidelines and studies in the context of individual clinical trials highlight the centrality of community stakeholder engagement in conducting ethically rigorous HIV prevention trials. We explored and identified challenges and facilitators for community stakeholder engagement in biomedical HIV prevention trials in diverse global settings. Our aim was to assess and deepen the empirical foundation for priorities included in the GPP guidelines and to highlight challenges in implementation that may merit further attention in subsequent GPP iterations. Methods From 2008–2012 we conducted an embedded, multiple case study centered in Thailand, India, South Africa and Canada. We conducted in-depth interviews and focus groups with respondents from different trial-related subsystems: civil society organization representatives, community advocates, service providers, clinical trialists/researchers, former trial participants, and key HIV risk populations. Interviews/focus groups were recorded, and coded using thematic content analysis. After intra-case analyses, we conducted cross-case analysis to contrast and synthesize themes and sub-themes across cases. Lastly, we applied the case study findings to explore and assess UNAIDS/AVAC GPP guidelines and the GPP Blueprint for Stakeholder Engagement. Results Across settings, we identified three cross-cutting themes as essential to community stakeholder engagement: trial literacy, including lexicon challenges and misconceptions that imperil sound communication; mistrust due to historical exploitation; and participatory processes: engaging early; considering the breadth of “community”; and, developing appropriate stakeholder roles. Site-specific challenges arose in resource-limited settings and settings where trials were halted. Conclusions This multiple case study revealed common themes underlying community stakeholder engagement across four country settings that largely mirror GPP goals and the

Although HIV prevention interventions for women are efficacious, long-term behavior change maintenance within power-imbalanced heterosexual relationships has been difficult. To explore the feasibility, content, and format of an HIV intervention for Latino couples, the authors conducted 13 focus groups with HIV/AIDS researchers, service providers, and heterosexual men and women in Puerto Rico, the Dominican Republic, and Mexico. Reasons that participants thought that men should be involved in prevention efforts included promotion of shared responsibility, creation of a safe environment for open conversation about sex, and increased sexual negotiation skills. Perceived barriers to men's involvement included cultural taboos, sexual conservatism associated with Catholicism and machismo, and power-imbalanced relationships. Participants stressed the need for recruitment of men within naturally occurring settings or by influential community leaders. Participants indicated that couples-level interventions would be successful if they used strong coed facilitators, included both unigender and mixed-gender discussion opportunities, and addressed personally meaningful topics. Implications of these findings are discussed.

Civil society organizations (CSOs) have significantly impacted on the politics of health research and the field of bioethics. In the global HIV epidemic, CSOs have served a pivotal stakeholder role. The dire need for development of new prevention technologies has raised critical challenges for the ethical engagement of community stakeholders in HIV research. This study explored the perspectives of CSO representatives involved in HIV prevention trials (HPTs) on the impact of premature trial closures on stakeholder engagement. Fourteen respondents from South African and international CSOs representing activist and advocacy groups, community mobilisation initiatives, and human and legal rights groups were purposively sampled based on involvement in HPTs. Interviews were conducted from February-May 2010. Descriptive analysis was undertaken across interviews and key themes were developed inductively. CSO representatives largely described positive outcomes of recent microbicide and HIV vaccine trial terminations, particularly in South Africa, which they attributed to improvements in stakeholder engagement. Ongoing challenges to community engagement included the need for principled justifications for selective stakeholder engagement at strategic time-points, as well as the need for legitimate alternatives to CABs as mechanisms for engagement. Key issues for CSOs in relation to research were also raised.

Abstract Clinical and basic science advances have raised considerable hope for achieving an HIV cure by accelerating research. This research is dominated primarily by issues about the nature and design of current and future clinical trials. Stakeholder engagement for HIV cure remains in its early stages. Our analysis examines timing and mechanisms of historical stakeholder engagement in other HIV research areas for HIV-uninfected individuals [vaccine development and pre-exposure prophylaxis (PrEP)], and HIV-infected individuals (treatment as prevention, prevention of mother-to-child transmission, and treatment of acute HIV infection) and articulate a plan for HIV cure stakeholder engagement. The experience from HIV vaccine development shows that early engagement of stakeholders helped manage expectations, mitigating the failure of several vaccine trials, while paving the way for subsequent trials. The relatively late engagement of HIV stakeholders in PrEP research may partly explain some of the implementation challenges. The treatment-related stakeholder engagement was strong and community-led from the onset and helped translation from research to implementation. We outline five steps to initiate and sustain stakeholder engagement in HIV cure research and conclude that stakeholder engagement represents a key investment in which stakeholders mutually agree to share knowledge, benefits, and risk of failure. Effective stakeholder engagement prevents misconceptions. As HIV cure research advances from early trials involving subjects with generally favorable prognosis to studies involving greater risk and uncertainty, success may depend on early and deliberate engagement of stakeholders.

South Africa bears the world’s largest burden of HIV with over 6.4 million people living with the virus. The South African government’s response to HIV has yielded remarkable results in recent years; over 13 million South Africans tested in a 2012 campaign and over 2 million people are on antiretroviral treatment. However, with an HIV & AIDS and STI National Strategic Plan aiming to get 80 percent of the population to know their HIV status by 2016, activists and public health policy makers argue that non-invasive HIV self-testing should be incorporated into the country HIV Counseling and Testing [HCT] portfolios. In-depth qualitative interviews (N = 12) with key stakeholders were conducted from June to July 2013 in South Africa. These included two government officials, four non-governmental stakeholders, two donors, three academic researchers, and one international stakeholder. All stakeholders were involved in HIV prevention and treatment and influenced HCT policy and research in South Africa and beyond. The interviews explored: interest in HIV self-testing; potential distribution channels for HIV self-tests to target groups; perception of requirements for diagnostic technologies that would be most amenable to HIV self-testing and opinions on barriers and opportunities for HIV-linkage to care after receiving positive test results. While there is currently no HIV self-testing policy in South Africa, and several barriers exist, participants in the study expressed enthusiasm and willingness for scale-up and urgent need for further research, planning, establishment of HIV Self-testing policy and programming to complement existing facility-based and community-based HIV testing systems. Introduction of HIV self-testing could have far-reaching positive effects on holistic HIV testing uptake, giving people autonomy to decide which approach they want to use for HIV testing, early diagnosis, treatment and care for HIV particularly among hard-to reach groups, including

In this introductory essay on the landscape of HIV prevention, my intent is to provide context for the subsequent topics discussed at the Symposium on Hormone Regulation of the Mucosal Environment in the female reproductive tract (FRT) and the Prevention of HIV infection: FRT immunity, mucosal microenvironment and HIV prevention, and the risk and impact of hormonal contraceptives on HIV transmission.
With the increasing emphasis on evaluating the effectiveness of community-based organizations' HIV prevention programs, the needs, concerns, and strategies related to having stakeholders participate in designing and conducting an outcome evaluation need to be discussed. Stakeholders' participation in outcome evaluation ensures its relevancy and fairness. Participatory outcome evaluation starts with assessing the feasibility of conducting an outcome evaluation and determining whether stakeholders have a need for an outcome evaluation. If an outcome evaluation is possible and needed, the areas in which stakeholders can make important contributions to the evaluation are negotiated with the stakeholders. The article also discusses strategies to improve stakeholders' use of the results of outcome evaluation.

Background In 2008, the US government mandated that HIV/AIDS care and treatment programs funded by the US President's Emergency Plan for AIDS Relief (PEPFAR) should shift from US-based international partners (IPs) to registered locally owned organizations (local partners, or LPs). The US Health Resources and Services Administration (HRSA) developed the Clinical Assessment for Systems Strengthening (ClASS) framework for technical assistance in resource-constrained settings. The ClASS framework involves all stakeholders in the identification of LPs' strengths and needs for technical assistance. Objective This article examines the role of ClASS in building capacity of LPs that can endure and adapt to changing financial and policy environments. Design All stakeholders (n=68) in Kenya, Zambia, and Nigeria who had participated in the ClASS from LPs and IPs, the US Centers for Disease Control and Prevention (CDC), and, in Nigeria, HIV/AIDS treatment facilities (TFs) were interviewed individually or in groups (n=42) using an open-ended interview guide. Thematic analysis revealed stakeholder perspectives on ClASS-initiated changes and their sustainability. Results Local organizations were motivated to make changes in internal operations with the ClASS approach, PEPFAR's competitive funding climate, organizational goals, and desired patient health outcomes. Local organizations drew on internal resources and, if needed, technical assistance from IPs. Reportedly, ClASS-initiated changes and remedial action plans made LPs more competitive for PEPFAR funding. LPs also attributed their successful funding applications to their preexisting systems and reputation. Bureaucracy, complex and competing tasks, and staff attrition impeded progress toward the desired changes. Although CDC continues to provide technical assistance through IPs, declining PEPFAR funds threaten the consolidation of gains, smooth program transition, and continuity of treatment services.

Objective Building a successful combination prevention program requires understanding the community’s local epidemiological profile, the social community norms that shape vulnerability to HIV and access to care, and the available community resources. We carried out a situational analysis in order to shape a comprehensive HIV prevention program that address local barriers to care at multiple contextual levels in the North West Province of South Africa. Method The situational analysis was conducted in two sub-districts in 2012 and guided by an adaptation of WHO’s Strategic Approach, a predominantly qualitative method, including observation of service delivery points and in-depth interviews and focus groups with local leaders, providers, and community members, in order to recommend context-specific HIV prevention strategies. Analysis began during fieldwork with nightly discussions of findings and continued with coding original textual data from the fieldwork notebooks and a select number of recorded interviews. Results We conducted over 200 individual and group interviews and gleaned four principal social barriers to HIV prevention and care, including: HIV fatalism, traditional gender norms, HIV-related stigma, and challenges with communication around HIV, all of which fuel the HIV epidemic. At the different levels of response needed to stem the epidemic, we found evidence of national policies and programs that are mitigating the social risk factors but little community-based responses that address social risk factors to HIV. Conclusions Understanding social and structural barriers to care helped shape our comprehensive HIV prevention program, which address the four ‘themes’ identified into each component of the program. Activities are underway to engage communities, offer community-based testing in high transmission areas, community stigma reduction, and a positive health, dignity and prevention program for stigma reduction and improve communication skills

Brick masons and mason tenders report a high prevalence of work-related musculoskeletal disorders (WMSDs), many of which can be prevented with changes in materials, work equipment or work practices. To explore the use of "best practices" in the masonry industry, NIOSH organized a 2-day meeting of masonry stakeholders. Attendees included 30 industry representatives, 5 health and safety researchers, 4 health/safety specialists, 2 ergonomic consultants, and 2 representatives of state workers' compensation programs. Small groups discussed ergonomic interventions currently utilized in the masonry industry, including factors affecting intervention implementation and ways to promote diffusion of interventions. Meeting participants also identified various barriers to intervention implementation, including business considerations, quality concerns, design issues, supply problems, jobsite conditions and management practices that can slow or limit intervention diffusion. To be successful, future diffusion efforts must not only raise awareness of available solutions but also address these practical concerns.

Sex work occurs to meet the demand for sexual services and is a universal phenomenon. In Africa sex work takes many forms and is an important source of income for many women. Yet sex worker reproductive health needs remain largely unmet. The criminalisation of sex work; community and service provider stigma; violence; substance use and limited access to health services and prevention commodities contribute to the high HIV burden evident among female sex workers in Africa. Following UNAIDS' three pillar approach to HIV prevention and sex work we present an overview of current opportunities, barriers and suggestions to improve HIV prevention policy and programming for sex work in Africa. Universal access to a comprehensive package of HIV services is the first pillar. Reproductive health commodities; voluntary and anonymous HIV counselling and testing; treatment of sexually transmitted infections, HIV and opportunistic infections; harm reduction for substance use and psychosocial support services make up the recommended package of services. The second pillar is a sex worker-supportive environment. The inclusion of sex worker programmes within national HIV strategic planning; sex worker-led community mobilisation and the establishment of sex work community networks (comprised of sex workers, health service providers, law enforcers and other stakeholders) enable effective programme implementation and are recommended. The reduction of sex worker vulnerability and addressing structural issues form the final pillar. The decriminalisation of sex work; development of supportive policy; gender equality and economic development are key factors that need to be addressed to increase sex worker resilience. Evidence supports the public health benefit of human rights based approaches to HIV prevention; moralistic and restrictive policy and laws towards sex work are harmful and should be removed. The establishment of these pillars will increase sex worker safety and enhance the

With an estimated 2.6 million new HIV infections diagnosed annually, the world needs new prevention strategies to partner with condom use, harm reduction approaches for injection drug users, and male circumcision. Antiretrovirals can reduce the risk of mother-to-child HIV transmission and limit HIV acquisition after occupational exposure. Macaque models and clinical trials demonstrate efficacy of oral or topical antiretrovirals used prior to HIV exposure to prevent HIV transmission, ie pre-exposure prophylaxis (PrEP). Early initiation of effective HIV treatment in serodiscordant couples results in a 96% decrease in HIV transmission. HIV testing to determine serostatus and identify undiagnosed persons is foundational to these approaches. The relative efficacy of different approaches, adherence, cost and long-term safety will affect uptake and impact of these strategies. Ongoing research will help characterize the role for oral and topical formulations and help quantify potential benefits in sub-populations at risk for HIV acquisition. PMID:22351302

Transgender persons are at high risk for HIV infection, but prevention efforts specifically targeting these people have been minimal. Part of the challenge of HIV prevention for transgender populations is that numerous individual, interpersonal, social, and structural factors contribute to their risk. By combining HIV prevention services with complementary medical, legal, and psychosocial services, transgender persons' HIV risk behaviors, risk determinants, and overall health can be affected simultaneously. For maximum health impact, comprehensive HIV prevention for transgender persons warrants efforts targeted to various impact levels-socioeconomic factors, decision-making contexts, long-lasting protections, clinical interventions, and counseling and education. We present current HIV prevention efforts that reach transgender persons and present others for future consideration.

Serodiscordant couples play an important role in maintaining the global HIV epidemic. This review summarizes biobehavioral and biomedical HIV prevention options for serodiscordant couples focusing on advances in 2013 and 2014, including World Health Organization guidelines and best-evidence for couples counseling, couples-based interventions, and the use of antiviral agents for prevention. In the past few years marked advances have been made in HIV prevention for serodiscordant couples and numerous ongoing studies are continuously expanding HIV prevention tools, especially in the area of pre-exposure prophylaxis. Uptake and adherence to antiviral therapy remains a key challenge. Additional research is needed to develop evidence-based interventions for couples, and especially for male-male couples. Randomized trials have demonstrated the prevention benefits of antiretroviral-based approaches among serodiscordant couples; however, residual transmission observed in recognized serodiscordant couples represents an important and resolvable challenge in HIV prevention.

The objective of this pilot study was to explore the knowledge of and preferences regarding effective biomedical interventions among high risk individuals attending a sexually transmitted diseases clinic, and to examine the effect of a brief information intervention on preference. Participants completed a baseline assessment, attended a presentation on human immunodeficiency virus (HIV) prevention methods, and completed a postintervention assessment. Outcome measures included: demographics and sexual risk factors, self-perceived HIV risk, and knowledge and attitudes regarding new biomedical methods of HIV prevention. After the baseline evaluation, participants were provided with information on new biomedical prevention strategies. Participants were given the option to review the information by reading a pamphlet or by viewing a brief video containing the same information. Participants (n=97) were female (n=51) and male (n=46). At baseline, only a small minority of participants were aware of the newer biomedical strategies to prevent HIV infection. Postintervention, 40% endorsed having heard about the use of HIV medications to prevent HIV infection; 72% had heard that male circumcision can decrease the risk of acquiring HIV infection in men; and 73% endorsed knowledge of the potential role of microbicides in decreasing the risk of acquiring HIV. Following the intervention, the most preferred prevention method was male condoms, followed by preexposure prophylaxis, and microbicides. The least preferred methods were male circumcision and female condoms. This study provides preliminary information on knowledge and attitudes regarding newer biomedical interventions to protect against HIV infection. PMID:25540597
Expansion of HIV testing and ART treatment are core strategies for achieving the ambitious global goal of ending the HIV epidemic by the end of 2030, and achieving the "90-90-90" target by 2020. In China, great progress in HIV control and prevention has been made; however, there is room to enhance the effectiveness of HIV-related strategies. In addition, some implemented strategies have not achieved their expected output. To confront the challenge of sexual transmission of HIV, which is the main route of transmission in China, more targeted HIV prevention strategies that lead to their expected outcomes are essential. It is important to strengthen existing strategies that have been proved effective. However, it is also critical to create innovative strategies, and there are five approaches to achieve this. First, a holistic perspective should be adopted, to better understand the current situation and problems. This means intervention strategies should give serious consideration of how to meet the sociocultural needs of target populations rather than merely carry out behavioral interventions. Second, community-based HIV prevention settings should have more important roles in providing HIV-related health care services. Moreover, to improve the effectiveness of these strategies, a problem-led working style should be integrated into HIV prevention measures overall. Third, thoroughly analyzing characteristics of the current HIV epidemic using more evidence-based considerations must be undertaken, to better control HIV sexual transmission. Fourth, continued improvement of AIDS prevention and control mechanisms is needed, to ensure their sustainable development. Last, it is necessary to involve more NGOs in HIV prevention work by strengthening their management and working capacities to provide HIV-related services. Also needed is further improvement in both technical and management capacities, so as to build a stable basis for effective response.

The controversy over "targeted" versus "universalistic" programs for HIV prevention has persisted throughout the history of the HIV/AIDS epidemic in the United States and in some European countries. Building on previous analyses, we outline methods for integrating universalistic and targeted HIV prevention programming. The outline considers possible synergy between targeted and universalistic programs, rather than a forced choice between the two. Components within this framework include a continuum of the intensity of targeted programs, specification of local risk behavior populations, categories of risk behavior, and HIV seroprevalence within local risk-behavior populations. Given the scarce resources currently available, preventing all new HIV infections is not a realistic public health goal, but with better use of current scientific knowledge, it should be possible to greatly reduce the rate of new HIV infections.

People living with human immunodeficiency virus (HIV) are living longer since the advent of effective combined antiretroviral therapy (cART). While cART substantially decreases the risk of developing some cancers, HIV-infected individuals remain at high risk for Kaposi sarcoma, lymphoma and several solid tumors. Currently HIV-infected patients represent an aging group, and malignancies have become a leading cause of morbidity and mortality. Tailored cancer-prevention strategies are needed for this population. In this review we describe the etiologic agents and pathogenesis of common malignancies in the setting of HIV, as well as current evidence for cancer prevention strategies and screening programs.

High HIV rates among cohabiting couples in many African countries have led to greater programmatic emphasis on spousal communication in HIV prevention. This study examines how demographic and socioeconomic characteristics of cohabiting adults influence their dyadic communication about HIV. A central focus of this research is on how the position of women relative to their male partners influences spousal communication about HIV prevention. The authors analyze gaps in spousal age and education and females' participation in household decision making as key factors influencing spousal communication about HIV, while controlling for sexual behaviors of both partners as well as other individual and contextual factors. Data were obtained from the 2003 Kenya Demographic and Health Survey for 1,388 cohabiting couples. Information regarding spousal communication was self-reported, assessing whether both, either, or neither partner ever discussed HIV prevention with the other. Analyses showed higher levels of education for the female partner and participation in household decision making are positively associated with spousal communication about HIV prevention. With females' education and other factors controlled, couples with more educated male partners were more likely to have discussed HIV prevention than couples in which both partners have the same level of education. Spousal communication was also positively associated with household wealth status and exposure to the mass media, but couples in which male partners reported having nonspousal sex in the past year were less likely to have discussed HIV prevention with their spouses. Findings suggest HIV prevention programs should promote female empowerment and encourage male participation in sexual health discussion.

Though African-American youth in the South are at high risk for HIV infection, abstinence until marriage education continues to be the only option in some public schools. Using community-based participatory research methods, we conducted 11 focus groups with African-American adults and youth in a rural community in North Carolina with high rates of HIV infection with marked racial disparities. Focus group discussions explored participant views on contributors to the elevated rates of HIV and resources available to reduce transmission. Participants consistently identified the public schools' sex education policies and practices as major barriers toward preventing HIV infection among youth in their community. Ideas for decreasing youth's risk of HIV included public schools providing access to health services and sex education. Policymakers, school administrators, and other stakeholders should consider the public school setting as a place to provide HIV prevention education for youth in rural areas.

People who inject drugs (PWID) are at increased HIV transmission risk because of unsafe injecting practices and a host of other individual, network, and structural factors. Thus, PWID have a great need for services within the Cascade of HIV prevention, diagnosis, care, and treatment (HIV Cascade). Yet the systems that monitor their progress through the Cascade are often lacking. Subsequently, fewer reliable data are available to guide programs targeting this key population (KP). Programmatic data, which are helpful in tracking PWID through the Cascade, also are limited because not all countries have harm reduction programming from which to estimate Cascade indicators. Also, due to stigma and the illegal nature of drug use, PWID may not disclose their drug use behavior or HIV status when accessing services. Consequently, PWID appear to have low HIV testing rates and, for those living with HIV, lower access to health services and lower viral suppression rates than do other KP groups. This commentary, based on outcomes from an international stakeholder meeting, identifies data gaps and proposes solutions to strengthen strategic information (SI), the systematic collection, analysis, and dissemination of information, to optimize HIV prevention, care, and treatment programming for PWID.

Purpose This study assesses how well two cartoons transfer knowledge of principles of work disability prevention among stakeholders, according to their level of experience. We also document stakeholders' perceptions of the usefulness of the cartoons. Method We performed a descriptive study. Two groups of stakeholders were recruited: (1) experienced (working for more than 2 years in work disability), (2) non-experienced (in training). A self-administered questionnaire with open-ended questions documented stakeholders' understanding of each cartoon box and their perception of the possible usefulness of the cartoons. We transformed qualitative responses into quantitative responses for descriptive purposes. We performed independent t tests to compare the groups' level of understanding, and content analysis for the perception of usefulness. Results Overall, 149 stakeholders (50 experienced and 99 non-experienced) participated and identified 79.4 and 61.4 % of all principles presented in each of the two cartoons respectively. Experienced stakeholders identified more principles compared to non-experienced stakeholders (p = 0.007). Both cartoons were perceived to be useful for knowledge transfer. Conclusions Principles were generally well identified in the cartoons by all participants. Cartoons can be used as an effective tool among stakeholders to achieve a common understanding in order to coordinate their actions.

Human immunodeficiency virus (HIV), causative agent of acquired immunodeficiency syndrome (AIDS), is a global health concern. To control its transmission, safe sex has been proposed as one of the strategies. Microbicides- intravaginal/intrarectal topical formulations of anti-HIV agents have also been proposed to prevent HIV transmission. Microbicides would provide protection by directly inactivating HIV or preventing the attachment, entry or replication of HIV in susceptible target cells as well as their dissemination from target cells present in semen or the host cells lining the vaginal/rectal wall to other migratory cells. Microbicides must be safe, effective following vaginal or rectal administration, and should cause minimal or no genital symptoms or inflammations following long-term repeated usage. However, a safe and efficacious anti-HIV microbicide is not yet available despite the fact that more than 60 candidate agents have been identified to have in vitro activity against HIV, several of which have advanced to clinical testing. Nonetheless, proof-of-concept of microbicides has been established based on the results of recent CAPRISA 004 clinical trials. In this article, the trends and challenges in the development of effective and safe microbicides to combat HIV transmission are reviewed. PMID:22310826

Although clinical experience and preliminary research suggest that some transgender people are at significant risk for HIV, this stigmatized group has so far been largely ignored in HIV prevention. As part of the development of HIV prevention education targeting the transgender population, focus groups of selected transgender individuals assessed their HIV risks and prevention needs. Data were gathered in the following four areas: (1) the impact of HIV/AIDS on transgender persons; (2) risk factors; (3) information and services needed; and (4) recruitment strategies. Findings indicated that HIV/AIDS compounds stigmatization related to transgender identity, interferes with sexual experimentation during the transgender 'coming out' process, and may interfere with obtaining sex reassignment. Identified transgender-specific risk factors include: sexual identity conflict, shame and isolation, secrecy, search for affirmation, compulsive sexual behaviour, prostitution, and sharing needles while injecting hormones. Community involvement, peer education and affirmation of transgender identity were stressed as integral components of a successful intervention. Education of health professionals about transgender identity and sexuality and support groups for transgender people with HIV/AIDS are urgently needed.

Introduction As a group, transwomen in Peru have the highest prevalence of HIV (>20%) in the country, but they have little access to HIV prevention, testing and care services. Until recently, Peru's national HIV programme did not recognize transwomen and had remained essentially static for decades. This changed in December 2014, when the Ministry of Health expressed its commitment to improve programming for transwomen and to involve transwomen organizations by prioritizing the development of a “Targeted Strategy Plan of STIs/HIV/AIDS Prevention and Comprehensive Care for Transwomen.” Discussion A policy dialogue between key stakeholders – Peru's Ministry of Health, academic scientists, civil society, transgender leaders and international agencies – created the conditions for a change in Peru's national HIV policy for transwomen. Supported by the effective engagement of all sectors, the Ministry of Health launched a plan to provide comprehensive HIV prevention and care for transwomen. The five-year plan includes new national guidelines for HIV prevention, care and support, and country-level investments in infrastructure and equipment. In addition to new biomedical strategies, the plan also incorporates several strategies to address structural factors that contribute to the vulnerability of transwomen. We identified three key factors that created the right conditions for this change in Peru's HIV policy. These factors include (1) the availability of solid evidence, based on scientific research; (2) ongoing efforts within the transwomen community to become better advocates of their own rights; and (3) a dialogue involving honest discussions between stakeholders about possibilities of changing the nation's HIV policy. Conclusions The creation of Peru's national plan for HIV prevention and care for transwomen shows that long-term processes, focused on human rights for transwomen in Peru, can lead to organizational and public-policy change.

Current ideas about HIV prevention include a mixture of primarily biomedical interventions, socio-mechanical interventions such as sterile syringe and condom distribution, and behavioral interventions. This article presents a framework for socially-integrated transdisciplinary HIV prevention that may improve current prevention efforts. It first describes one socially-integrated transdisciplinary intervention project, the Transmission Reduction Intervention Project. We focus on how social aspects of the intervention integrate its component parts across disciplines and processes at different levels of analysis. We then present socially-integrated perspectives about how to improve combination antiretroviral treatment (cART) processes at the population level in order to solve the problems of the treatment cascade and make "treatment as prevention" more effective. Finally, we discuss some remaining problems and issues in such a social transdisciplinary intervention in the hope that other researchers and public health agents will develop additional socially-integrated interventions for HIV and other diseases.
Background There is a huge interest by faith-based organizations (FBOs) in sub-Saharan Africa and elsewhere in HIV prevention interventions that build on the religious aspects of being. Successful partnerships between the public health services and FBOs will require a better understanding of the conceptual framing of HIV prevention by FBOS to access for prevention intervention, those concepts the churches of various denominations and their members would support or endorse. This study investigated the conceptual framing of HIV prevention among church youths in Botswana; - a country with one of the highest HIV prevalence in the world. Method Participants were 213 Pentecostal church members (67% female; age range 12 to 23 years; median age = 19 years). We engaged the participants in a mixed-method inductive process to collect data on their implicit framing of HIV prevention concepts, taking into account the centrality of religion concepts to them and the moderating influences of age, gender and sexual experience. After, we analysed the data using multi-dimensional scaling (MDS) and hierarchical cluster analysis (HCA) to map the ways the church youths framed HIV prevention. Results The findings suggest the church youth to conceptually frame their HIV prevention from both faith-oriented and secular-oriented perspectives, while prioritizing the faith-oriented concepts based on biblical teachings and future focus. In their secular-oriented framing of HIV prevention, the church youths endorsed the importance to learn the facts about HIV and AIDS, understanding of community norms that increased risk for HIV and prevention education. However, components of secular-oriented framing of HIV prevention concepts were comparatively less was well differentiated among the youths than with faith-oriented framing, suggesting latent influences of the church knowledge environment to undervalue secular oriented concepts. Older and sexually experienced church youths in their framing

ABSTRACT Biomedical preventions for HIV, such as vaccines, microbicides or pre-exposure prophylaxis (PrEP) with antiretroviral drugs, can each only partially prevent HIV-1 infection in most human trials. Oral PrEP is now FDA approved for HIV-prevention in high risk groups, but partial adherence reduces efficacy. If combined as biomedical preventions (CBP) an HIV vaccine could provide protection when PrEP adherence is low and PrEP could prevent vaccine breakthroughs. Other types of PrEP or microbicides may also be partially protective. When licensed, first generation HIV vaccines are likely to be partially effective. Individuals at risk for HIV may receive an HIV vaccine combined with other biomedical preventions, in series or in parallel, in clinical trials or as part of standard of care, with the goal of maximally increasing HIV prevention. In human studies, it is challenging to determine which preventions are best combined, how they interact and how effective they are. Animal models can determine CBP efficacy, whether additive or synergistic, the efficacy of different products and combinations, dose, timing and mechanisms. CBP studies in macaques have shown that partially or minimally effective candidate HIV vaccines combined with partially effective oral PrEP, vaginal PrEP or microbicide generally provided greater protection than either prevention alone against SIV or SHIV challenges. Since human CBP trials will be complex, animal models can guide their design, sample size, endpoints, correlates and surrogates of protection. This review focuses on animal studies and human models of CBP and discusses implications for HIV prevention. PMID:27679928
No cure has been found for HIV/AIDS. Therefore, until one is found which is affordable and feasible for use in developing countries, preventing HIV infection is the best way to combat the HIV/AIDS pandemic. All of the many biological characteristics of HIV which affect its rate of spread in a population can be affected through individual behavior. The two most important behaviors which spread HIV are having sexual intercourse with an HIV-infected sex partner without using a condom and sharing unsterilized drug injecting equipment. Strategies to reduce risky behavior include providing information, lowering the costs of condom use and safe injecting behavior, and raising the costs of risky behavior. The costs of condom use include the financial and time costs of buying the condoms, the potential inconvenience and social embarrassment of buying and using them, and reduced pleasure among some users. IV drug users face the problems of getting into and remaining in drug treatment programs, and obtaining sterile injecting equipment. Government priorities in preventing HIV/AIDS and mobilizing political support against AIDS are discussed.

Background Minority engagement in HIV prevention research can improve the process and products of research. Using community-based participatory research (CBPR) to develop capacity-building tools can promote community awareness of HIV prevention, clinical research, and community roles in research. Objectives We sought to describe a CBPR approach to curriculum development to increase HIV prevention research literacy among Blacks ages 18 to 30. Methods Community members and researchers documented the iterative and participatory nature of curriculum development and lessons learned. Results/Lessons Learned We used specific strategies to support and verify multi-stakeholder engagement, team building, capacity building, and shared decision making. Objective or formal assessments of baseline capacity, ongoing stakeholder engagement, and reinforcing the value of multiple perspectives can promote further equity in curriculum development between researchers and community members. Conclusions The iterative process of shared discussion, development, and consensus building strengthened collaboration between stakeholder groups and produced a stronger, more culturally appropriate curriculum to promote HIV prevention research engagement among young Blacks.

Cash payments to improve health outcomes have been used for many years, however, their use for HIV prevention is new and the impact not yet well understood. We provide a brief background on the rationale behind using cash to improve health outcomes, review current studies completed or underway using cash for prevention of sexual transmission of HIV, and outline some key considerations on the use of cash payments to prevent HIV infections. We searched the literature for studies that implemented cash transfer programs and measured HIV or HIV-related outcomes. We identified 16 studies meeting our criteria; 10 are completed. The majority of studies have been conducted with adolescents in developing countries and payments are focused on addressing structural risk factors such as poverty. Most have seen reductions in sexual behavior and one large trial has documented a difference in HIV prevalence between young women getting cash transfers and those not. Cash transfer programs focused on changing risky sexual behaviors to reduce HIV risk suggest promise. The context in which programs are situated, the purpose of the cash transfer, and the population will all affect the impact of such programs; ongoing RCTs with HIV incidence endpoints will shed more light on the efficacy of cash payments as strategy for HIV prevention.

HIV has reached epidemic proportions among African Americans in the USA but certain urban contexts appear to experience a disproportionate disease burden. Geographic information systems mapping in Philadelphia indicates increased HIV incidence and prevalence in predominantly Black census tracts, with major differences across adjacent communities. What factors shape these geographic HIV disparities among Black Philadelphians? This descriptive study was designed to refine and validate a conceptual model developed to better understand multi-level determinants of HIV-related risk among Black Philadelphians. We used an expanded ecological approach to elicit reflective perceptions from administrators, direct service providers and community members about individual, social and structural factors that interact to protect against or increase the risk for acquiring HIV within their community. Gender equity, social capital and positive cultural mores (e.g., monogamy, abstinence) were seen as the main protective factors. Historical negative contributory influences of racial residential segregation, poverty and incarceration were among the most salient risk factors. This study was a critical next step toward initiating theory-based, multi-level community-based HIV prevention initiatives.

The success of the HIV Prevention Trials Network 052 trial has led to revisions in HIV-1 treatment guidelines. Antiretroviral therapy may reduce the risk of HIV-1 transmissions at the population level. The design of successful treatment as prevention interventions will be predicated on a comprehensive understanding of the spatial, temporal, and biological dynamics of heterosexual men who have sex with men and intravenous drug user epidemics. Viral phylogenetics can capture the underlying structure of transmission networks based on the genetic interrelatedness of viral sequences and cluster networks that could not be otherwise identified. This article describes the phylogenetic expansion of the Montreal men who have sex with men epidemic over the last decade. High rates of coclustering of primary infections are associated with 1 infection leading to 13 onward transmissions. Phylogeny substantiates the role of primary and recent stage infection in transmission dynamics, underlying the importance of timely diagnosis and immediate antiretroviral therapy initiation to avert transmission cascades.

In response to the release of the National HIV/AIDS Strategy, the Centers for Disease Control and Prevention developed the “Enhanced Comprehensive HIV Prevention Planning” (ECHPP) project, which provided support to health departments in 12 Metropolitan Statistical Areas with the highest AIDS prevalence to strengthen local HIV programs. We describe a case study of how one MSA, Miami-Dade County, developed and implemented a locally tailored plan. Examples include actions to reinforce local partnerships and identify neighborhoods with highest unmet needs; an improved condom distribution system to assist local HIV care providers; collaboration with local stakeholders to establish a new walk-in center for transgender client needs; and overcoming incompatibilities in health department and Ryan White program computer record systems to facilitate faster and more efficient patient services. These examples show how jurisdictions both within Florida and elsewhere can create low-cost and sustainable activities tailored to improve local HIV prevention needs. PMID:26785398

The Women and AIDS Research Program (International Center for Research on Women) has identified a series of obstacles to preventing HIV infection among women, including social norms that mandate female ignorance about sexual matters, women's economic dependence on men, widespread acceptance of male promiscuity, and violence against women. Most AIDS prevention programs fail to challenge these contextual determinants and continue to focus on the promotion of condom use among men. Recommendations to empower women and improve their status are dismissed as long-term measures outside the domain of AIDS prevention. Feasible, however, is the modification of existing AIDS prevention programs to ensure they are gender-sensitive. This would mean measures such as providing services at times that are convenient to women and integrating services to reduce waiting and travelling times. To address the contextual issues at the root of women's vulnerability to HIV, AIDS prevention programs can link up with economic interventions such as credit programs, agricultural extension services, and women's cooperatives. Moreover, AIDS programs can provide HIV-infected women with social support through group educational sessions or counseling. Finally, because improvements in women's socioeconomic status are essential for the success of all AIDS prevention, program managers should be in the forefront of broader struggles to enact policy changes to eliminate gender-based discrimination and inequality.

INTRODUCTION Workplace disability prevention is important, but stakeholders can differ in their appreciation of such interventions. We present a responsive evaluation of a workplace disability prevention intervention in a Canadian healthcare organization. Three groups of stakeholders were included: designers of the intervention, deliverers, and workers. The aim was to examine the appreciation of this intervention by analyzing the discrepancies with respect to what these various stakeholders see as the causes of work disability, what the intervention should aim at to address this problem, and to what extent the intervention works in practice. METHODS A qualitative research method was used, including data-triangulation: (a) documentary materials; (b) semi-structured interviews with the deliverers and workers (n = 14); (c) participatory observations of group meetings (n = 6); (d) member-checking meetings (n = 3); (e) focus-group meetings (n = 2). A grounded theory approach, including some ethnographic methodology, was used for the data-analysis. RESULTS Stakeholders' perceptions of causes for work disability differ, as do preferred strategies for prevention. Designers proposed work-directed measures to change the workplace and work organizations, and individual-directed measures to change workers' behaviour. Deliverers targeted individual-directed measures, however, workers were mostly seeking work-directed measures. To assess how the intervention was working, designers sought a wide range of outcome measures. Deliverers focused on measurable outcomes targeted at reducing work time-loss. Workers perceived that this intervention offered short-term benefits yet fell short in ensuring sustainable return-to-work. CONCLUSION This study provides understanding of where discrepancies between stakeholders' perceptions about interventions come from. Our findings have implications for workplace disability prevention intervention development, implementation and evaluation

The purpose of this article is to illustrate how an ecodevelopmental perspective on risk and protection can be applied to the study and prevention of unsafe sexual behavior in Hispanic immigrant adolescents. Special attention is given to culturally based ecodevelopmental risk and protective processes that may influence unsafe sexual behavior among Hispanic adolescents. Principles for designing prevention programs to offset these risks are offered on the basis of an ecodevelopmental HIV prevention program that has been developed and is currently being tested.

Participation of different community sectors, including the private business sector, is necessary to fight the HIV/AIDS epidemic. Local businesses may be reluctant to participate in HIV prevention because of fear of negative customer reactions and loss of revenue. This study examines the extent to which residents of two communities in San Diego, California, would support HIV prevention initiatives in local businesses. A population-based household survey (N = 200) is conducted in two communities with higher versus lower risk for HIV. The survey includes questions regarding the acceptability of HIV prevention activities, such as condom and brochure distribution in businesses, and history of exposure to HIV prevention activities in local businesses. Most residents agree that (a) business involvement in prevention activities would reduce HIV (92%), (b) free or low-cost condoms available in businesses could prevent the spread of HIV (90.9%) and increase condom accessibility (87%), and (c) they would prefer to shop at businesses that supported HIV prevention versus those that did not (87.4%). These findings suggest that HIV prevention in local businesses would be supported by residents and would be unlikely to adversely affect business profits. This information could be used to design interventions to engage local businesses in HIV-prevention efforts.

The prevalence rate of HIV infection in jails and prisons is approximately 5 times the rate in the U.S. general population. The authors surveyed state prison officials to assess HIV testing and HIV prevention policies--specifically voluntary testing, group HIV prevention counseling, and peer education--in the 50 states and to determine whether those policies are associated with the characteristics of the state and its prison population.

Purpose To explore primary care providers' HIV prevention practices for older adults. Primary care providers' perceptions and awareness were explored to understand factors that affect their provision of HIV prevention materials and HIV screening for older adults. Design and Method Data were collected through 24 semistructured interviews with primary care providers (i.e., physicians, physician assistants, and nurse practitioners) who see patients older than 50 years. Results Results reveal facilitators and barriers of HIV prevention for older adults among primary care providers and understanding of providers' HIV prevention practices and behaviors. Individual, patient, institutional, and societal factors influenced HIV prevention practices among participants, for example, provider training and work experience, lack of time, discomfort in discussing HIV/AIDS with older adults, stigma, and ageism were contributing factors. Furthermore, factors specific to primary and secondary HIV prevention were identified, for instance, the presence of sexually transmitted infections influenced providers' secondary prevention practices. Implications HIV disease, while preventable, is increasing among older adults. These findings inform future research and interventions aimed at increasing HIV prevention practices in primary care settings for patients older than 50. PMID:25736425

Given that the communities which are most vulnerable to HIV often have little control over their own lives and their health-related behaviour, HIV prevention policies increasingly recommend that HIV prevention projects work to build relationships with powerful external groups (i.e., build "bridging social capital"). To aid conceptualisation of how community organisations may build such social capital, this paper outlines a typology of strategies for influencing local stakeholders. We present a study of two successful Indian sex workers' organisations, VAMP and DMSC, focusing on how the organisations have influenced three groups of stakeholders, namely police, politicians and local social organisations. Interviews with project employees (45), with representatives of the three groups of stakeholders (12) and fieldwork diaries recording 6 months of observation in each site provide the data. Three approaches emerged. "Persuading" refers to the practice of holding information-giving meetings with stakeholders and requesting their support. It appears to build "weak social ties". "Protesting" entails a collective confrontation with stakeholders, and appears to be useful when the stakeholder has a public image to protect that would be tarnished by protest, and when the protestors can stake a legitimate claim that their rights are being denied. In "exchanging favours", the sex workers' organisations find creative ways to position themselves as offering valued resources to their stakeholders (such as useful information on criminal activities for the police, a stage and audience for politicians or a celebration for local social organisations) as incentives for their support. In conclusion, we discuss the strengths and weaknesses of each approach, the implications for social capital theorising and implications for community HIV prevention.

Non-antiretroviral microbicide candidates were previously explored as a female-controlled method of preventing sexual transmission of HIV. These products contained non-HIV specific active compounds that were ultimately found to disrupt the vaginal epithelium, cause increased immune activation in the female genital tract, disturb vaginal flora, and/or cause other irritation that precluded their use as vaginal microbicides. Due to the failure of these first-generation candidates, there was a shift in focus to developing HIV pre-exposure prophylaxis and microbicides containing small-molecule antiretrovirals. Even with the limited success of the antiretroviral-based microbicides in clinical evaluations and no commercially available products, there has been significant progress in microbicide research. The lessons learned from previous trials have given rise to more rigorous preclinical evaluation that aims to be better at predicting microbicide efficacy and safety and to novel formulation and delivery technologies. These advances have resulted in renewed interest in developing non-antiretroviral-based microbicides, such as broadly neutralizing antibodies (for example, VRC01) and anti-viral proteins (for example, Griffithsin), as options for persons not wanting to use antiretroviral drugs, and for their potential to prevent multiple sexually transmitted infections.

This essay discusses the rationale for targeting HIV prevention programs to the general public, as opposed to focusing strictly on high-risk populations. The author first considers varying definitions of the term "general public," then explains the goal of general public education programs. Additionally, the author lays down the theoretical foundations of general audience education programs and weights related research findings. Finally, he offers recommendations for future practice. Noting the complex socioecological elements involved in health behavior, the author argues in favor of a broad definition for the general public. This broad outlook allows programs to still target high-risk population while not bypassing low-risk persons, who are sometimes treated as irrelevant because they do not contribute to excess morbidity or mortality. When it comes to HIV educational programs for the general public, their goals should be to instruct the public on how the virus is transmitted, to allay unfounded fears, and to increase the level of support for AIDS prevention and control. Such a program would require a theoretical basis drawn from multiple sources: health education, health communication, clinical and social psychology, and social marketing. The author concludes by proving recommendations designed to reinforce existing programs: 1) strengthen efforts to ensure that all people are educated about HIV and to encourage people to treat AIDS patients with compassion; 2) continue to explore for the most effective communication channels; 3) strengthen the communication infrastructure for those who are disenfranchised from health education; and 4) strengthen evaluation efforts of health communication programs.

We propose a set of common factors in evidence-based interventions (EBI) for HIV prevention, which cut across theoretical models of behavior change. Three existing literatures support this agenda: (1) Common factors in psychotherapy; (2) core elements from the Centers for Disease Control and Prevention EBIs; and (3) component analyses of EBI. To stimulate discussion among prevention researchers, we propose a set of common factors at the highest level of abstraction that describe what all effective programs do: (1) establish a framework to understand behavior change; (2) convey issue-specific and population-specific information necessary for healthy actions; (3) build cognitive, affective, and behavioral self-management skills; (4) address environmental barriers to implementing health behaviors; and (5) provide tools to develop ongoing social and community support for healthy actions. A focus on common factors will enhance research on new HIV prevention interventions, encourage collaboration among researchers, provide guidelines for adapting EBI, and simplify and speed the adoption of EBI for providers.

As antiretroviral treatment of HIV infection has become increasingly accessible, attention has focused on whether these drugs can used for prevention because of increased tolerability of newer medications, decreased cost, and the limitations of other approaches. We review the status of antiretroviral HIV prevention, including chemoprophylaxis, as well as the effects of treatment of infected individuals on prevention. It is possible that the life-saving agents that have transformed the natural history of AIDS can be a critical component of HIV prevention efforts, but their ultimate role in affecting HIV transmission dynamics remains to be defined.

The Centers for Disease Control and Prevention has undertaken an advisory process to update its national HIV prevention plan. We offer observations on the magnitude of HIV prevention challenges in the United States and reflect on how these challenges might influence the structure of a new HIV prevention plan. We recommend a plan structure that (1) is based on fundamental principles of prevention, (2) enables accountability and mid-course correction, and (3) if achieved, would result in historic changes in the US HIV epidemic. The recommended plan structure would differentially prioritize serostatus determination and prevention and care interventions for people living with HIV while retaining goals directed at high-risk HIV-negative and general population members.

Introduction Currently, Tanzania's HIV prevalence is 5.7%. Gender inequality and Gender Based Violence (GBV) are among factors fuelling the spread of HIV in Tanzania. This study was conducted to assess universal access to HIV prevention services among GBV survivors in Iringa and Dar-es-Salaam where HIV prevalence is as high as 14.7% and 9% respectively compared to a national average of 5.7%. Methods In 2010, a mixed methods study using triangulation model was conducted in Iringa and Dar-es-Salaam regions to represent rural and urban settings respectively. Questionnaires were administered to 283 randomly selected survivors and 37 health providers while 28 in-depth interviews and 16 focus group discussions were conducted among various stakeholders. Quantitative data was analyzed in SPSS by comparing descriptive statistics while qualitative data was analyzed using thematic framework approach. Results Counseling and testing was the most common type of HIV prevention services received by GBV survivors (29%). Obstacles for HIV prevention among GBV survivors included: stigma, male dominance culture and fear of marital separation. Bribery in service delivery points, lack of confidentiality, inadequate GBV knowledge among health providers, and fear of being involved in legal matters were mentioned to be additional obstacles to service accessibility by survivors. Reported consequences of GBV included: psychological problems, physical trauma, chronic illness, HIV infection. Conclusion GBV related stigma and cultural norms are obstacles to HIV services accessibility. Initiation of friendly health services, integration of GBV into HIV services and community based interventions addressing GBV related stigma and cultural norms are recommended. PMID:23467278

Background & Objectives: HIV is a major health challenge for prison authorities. HIV in prisons has implications for HIV in the general community. The aim of this paper was to gather information on HIV risk, prevalence, prevention and treatment in prisons in India. Methods: Relevant published and unpublished reports and information were sought in order to provide a coherent picture of the current situation relating to HIV prevention, treatment and care in prisons in India. Information covered prison management and population statistics, general conditions in prisons, provision of general medical care and the HIV situation in prison. Results: No data on drug injection in prison were identified. Sex between men was reported to be common in some Indian prisons. A national study found that 1.7 per cent of inmates were HIV positive. Some prisons provided HIV education. Condom provision was considered illegal. A few prisoners received drug treatment for drug use, HIV infection or co-infection with sexually transmitted infections (STIs). Interpretation & conclusions: HIV prevalence in prisons in India was higher than that in the general community. Regular monitoring of information on HIV risk behaviours and prevalence in Indian prisons is strongly recommended. Evidence based treatment for drug injectors and nation-wide provision of HIV prevention strategies are urgently required. Voluntary counselling, testing and treatment for HIV and STIs should be provided. PMID:21245617

This article describes an adolescent, peer-education training program in Jamaica that was developed and operated by the Red Cross Societies of Jamaica and the US and was funded by AIDSCAP. The program aimed to develop a training system to prepare youth peer educators in preventing the spread of HIV infections and sexually transmitted diseases. The goal was to increase knowledge about, change attitudes toward, and develop prevention skills for HIV/AIDS. The initial program was to be replicated on a large scale and be sustainable over time. The program was developed in response to the 1500+ Jamaicans diagnosed with AIDS and the 20,000 or so with HIV infections. Transmission is mostly heterosexual. 15% of girls and 47% of boys are sexually active by 14 years of age, and almost 50% of syphilis and gonorrhea cases are among adolescents. The national training program relies on peer educators, aged 14-19 years, who are literate to the 6th-grade level. Training sessions are conducted for 10-21 persons/session for 27 hours over 3 weekends. Training relies on engaging games and activities. Trainees are taught how to facilitate 14 specific activities, including the correct way to use a condom. Peer educators work together in groups of twos or threes among groups of 10-15 adolescents, aged 10-15 years. By the third year of operation, most of the systems and materials were in place and the program expanded; cost-benefit analysis revealed that costs were returned. The program has continued with a variety of funds and delivery systems and new funding will likely shift the program emphasis. The program has survived with the enthusiasm and support of the trainers. Other start-up programs should ensure the involvement of youth at all stages of development.

Socio-cultural factors and HIV-related misinformation contribute to the increasing number of Chilean women living with HIV. In spite of this, and to date, few culturally specific prevention activities have been developed for this population. The goal of the present study was to elicit the perspectives of low-income Chilean women regarding HIV and relevant socio-cultural factors, as a forerunner to the development of a culturally appropriate intervention. As part of a mixed-methods study, fifty low-income Chilean women participated in a survey and twenty were selected to participate in prevention, in-depth interviews. Results show evidence of widespread misinformation and misconceptions related to HIV/AIDS. Machismo and marianismo offer major barriers to prevention programme development. Future HIV prevention should stress partner communication, empowerment and improving the education of women vulnerable to HIV. PMID:18432428

Background: Women and adolescent girls bear a significant burden of the global HIV pandemic. Both behavioral and biomedical prevention approaches have been shown to be effective. In order to foster the most effective combination HIV-prevention approaches for women and girls, it is imperative to understand the unique biological, social, and structural considerations that increase vulnerability to acquiring HIV within this population. Primary Study Objective: The purpose of this article is to propose novel ideas for personalized biobehavioral HIV prevention for women and adolescent girls. The central argument is that we must transcend unilevel solutions for HIV prevention toward comprehensive, multilevel combination HIV prevention packages to actualize personalized biobehavioral HIV prevention. Our hope is to foster transnational dialogue among researchers, practitioners, educators, and policy makers toward the actualization of the proposed recommendations. Methods: We present a commentary organized to review biological, social, and structural factors that increase vulnerability to HIV acquisition among women and adolescent girls. The overview is followed by recommendations to curb HIV rates in the target population in a sustainable manner. Results: The physiology of the lower female reproductive system biologically increases HIV risk among women and girls. Social (eg, intimate partner violence) and structural (eg, gender inequality) factors exacerbate this risk by increasing the likelihood of viral exposure. Our recommendations for personalized biobehavioral HIV prevention are to (1) create innovative mechanisms for personalized HIV risk—reduction assessments; (2) develop mathematical models of local epidemics; (3) prepare personalized, evidence-based combination HIV risk—reduction packages; (4) structure gender equity into society; and (5) eliminate violence (both physical and structural) against women and girls. Conclusions: Generalized programs and

Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

Antiviral agents can be used to prevent HIV transmission before exposure as preexpo-sure prophylaxis (PrEP), after exposure as postexposure prophylaxis, and as treatment of infected people for secondary prevention. Considerable research has shed new light on antiviral agents for PrEP and for prevention of secondary HIV transmission. While promising results have emerged from several PrEP trials, the challenges of poor adherence among HIV-negative clients and possible increase in sexual risk behaviors remain a concern. In addition, a broader pipeline of antiviral agents for PrEP that focuses on genital tract pharmacology and safety and resistance issues must be developed. Antiretroviral drugs have also been used to prevent HIV transmission from HIV-infected patients to their HIV-discordant sexual partners. The HIV Prevention Trials Network 052 trial demonstrated nearly complete prevention of HIV transmission by early treatment of infection, but the generalizability of the results to other risk groups – including intravenous drug users and MSM – has not been determined. Most importantly, the best strategy for use of antiretroviral agents to reduce the spread of HIV at either the individual level or the population level has not been developed, and remains the ultimate goal of this area of investigation.

HIV in Australia was first diagnosed in NSW in the early 1980s, and has had a significant effect on public health. The NSW Government commenced its investment in HIV/AIDS in 1984 and the investment now encompasses research, primary and secondary prevention, and care, treatment and support for people living with HIV/AIDS. A recent study examined the historical impact of the HIV/AIDS epidemic and projected its future impact in NSW. The analysis indicates that the NSW HIV/AIDS investment program has been highly effective in reducing HIV transmission, and has also been cost effective in: avoiding future health-care costs; life years saved; and quality of life benefits. The analysis also indicates that any scaling back of prevention initiatives would result in an increase in the number of people living with HIV.

HIV epidemiology informs prevention trial design and program planning. Nine clinical research centers (CRC) in sub-Saharan Africa conducted HIV observational epidemiology studies in populations at risk for HIV infection as part of an HIV prevention and vaccine trial network. Annual HIV incidence ranged from below 2% to above 10% and varied by CRC and risk group, with rates above 5% observed in Zambian men in an HIV-discordant relationship, Ugandan men from Lake Victoria fishing communities, men who have sex with men, and several cohorts of women. HIV incidence tended to fall after the first three months in the study and over calendar time. Among suspected transmission pairs, 28% of HIV infections were not from the reported partner. Volunteers with high incidence were successfully identified and enrolled into large scale cohort studies. Over a quarter of new cases in couples acquired infection from persons other than the suspected transmitting partner. PMID:25602351

Abstract Biomedical HIV prevention strategies, such as pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), represent new opportunities to reduce critically high HIV infection rates among young black men who have sex with men (YBMSM). We report results of 24 dyadic qualitative interviews (N=48), conducted in Los Angeles, CA, exploring how YBMSM and their friends view PrEP and PEP. Interviews were analyzed using a grounded theory approach. Participants had widely divergent levels of knowledge about these prevention methods. Misconceptions and mistrust regarding PrEP were common, and concerns were expressed about PrEP-related stigma and the potential for gossip among peers who might assume a person on PrEP was HIV-positive. Yet participants also framed PrEP and PEP as valuable new options within an expanded “tool kit” of HIV prevention strategies that created possibilities for preventing new HIV infections, dating men with a different HIV status, and decreased anxiety about exposure to HIV. We organized themes around four main areas: (1) information and misinformation about biomedical HIV prevention; (2) expectations about PrEP, sexual behavior, and stigma; (3) gossip, disclosure, and “spreading the word” about PrEP and PEP; and (4) the roles of PrEP and PEP in an expanded HIV prevention tool kit. The findings suggest a need for guidance in navigating the increasingly complex array of HIV-prevention options available to YBMSM. Such “prevention navigation” could counter misconceptions and address barriers, such as stigma and mistrust, while helping YBMSM make informed selections from among expanded HIV prevention options.

Socio-cultural factors and HIV-related misinformation contribute to the increasing number of Chilean women living with HIV. In spite of this, and to date, few culturally specific prevention activities have been developed for this population. The goal of the present study was to elicit the perspectives of low-income Chilean women regarding HIV and relevant socio-cultural factors, as a forerunner to the development of a culturally appropriate intervention. As part of a mixed-methods study, fifty low-income Chilean women participated in a survey and twenty were selected to participate in prevention, in-depth interviews. Results show evidence of widespread misinformation and misconceptions related to HIV/AIDS. Machismo and marianismo offer major barriers to prevention programme development. Future HIV prevention should stress partner communication, empowerment and improving the education of women vulnerable to HIV.

An understanding of men's motivations to avoid risk behavior is needed to create efficacious HIV prevention programs for HIV-positive men who have sex with men (MSM). This study investigates the relationship between sexual risk behavior and HIV prevention altruism, which is defined as the values, motivations, and practices of caretaking towards one's sexual partners to prevent the transmission of HIV. In a sample of 637 HIV-positive MSM, HIV prevention altruism significantly protects against serodiscordant unprotected anal intercourse (SDUAI) in crude analysis, but not after adjustment for drug use and compulsive sexual behavior. HIV prevention altruism is also related to not engaging in anal intercourse, but is not related to serodisclosure to secondary partners. Lack of altruism appears related to sexual risk behavior in HIV-positive MSM, although other psychological and contextual factors play significant roles. The promotion of HIV prevention altruism may provide a formidable new direction for HIV prevention programs.

ABSTRACT Adolescents and young people account for 40% of all new HIV infections each year, with South Africa one of the hardest hit countries, and having the largest population of people living with HIV. Although adolescent HIV prevention has been delivered through diverse modalities in South Africa, and although family-based approaches for adolescent HIV prevention have great potential for highly affected settings such as South Africa, there is a scarcity of empirically tested family-based adolescent HIV preventive interventions in this setting. We therefore conducted focus groups and in-depth interviews with key informants including clinicians, researchers, and other individuals representing organizations providing HIV and related health services to adolescents and parents (N = 82). We explored family perspectives and interactions around topics such as communication about sex, HIV, and relationships. Participants described aspects of family interactions that presented both challenges and opportunities for family-based adolescent HIV prevention. Parent–child communication on sexual topics were taboo, with these conversations perceived by some adults as an invitation for children to engage in HIV risk behavior. Parents experienced social sanctions for discussing sex and adolescents who asked about sex were often viewed as disrespectful and needing discipline. However, participants also identified context-appropriate strategies for addressing family challenges around HIV prevention including family meetings, communal parenting, building efficacy around parent–adolescent communication around sexual topics, and the need to strengthen family bonding and positive parenting. Findings indicate the need for a family intervention and identify strategies for development of family-based interventions for adolescent HIV prevention. These findings will inform design of a family intervention to be tested in a randomized pilot trial (ClinicalTrials.gov #NCT02432352). PMID

The majority of HIV prevention studies and programs have targeted individuals or operated at the community level. This has also been the standard approach when incorporating technology (e.g., web-based, smartphones) to help improve HIV prevention efforts. The tides have turned for both approaches: greater attention is now focusing on couples-based HIV prevention and using technology to help improve these efforts for maximizing reach and potential impact. To assess the extent that technology has been used to help advance HIV prevention with couples, a literature review was conducted using four databases and included studies that collected data from 2000 to early 2015. Results from this review suggest technology has primarily been used to help advance HIV prevention with couples as a tool for 1) recruitment and data collection and 2) intervention development. Challenges and limitations of conducting research (e.g., validity of dyadic data) along with future directions for how technology (e.g. mHealth, wearable sensors) can be used to advance HIV prevention with couples are then discussed. Given the growing and near ubiquitous use of the Internet and smartphones, further efforts in the realm of mhealth (e.g., applications or “apps”) and eHealth are needed to develop novel couples-focused HIV preventive interventions.

Introduction Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation. Objectives We aimed to identify the key domains of community mobilization (CM) essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting. Method We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge. Results CM domains include: 1) shared concerns, 2) critical consciousness, 3) organizational structures/networks, 4) leadership (individual and/or institutional), 5) collective activities/actions, and 6) social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks. Conclusions To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural

Community engagement is crucial to ongoing development and testing of sorely needed new biomedical HIV prevention technologies. Yet, negative trial results raise significant challenges for community engagement in HIV prevention trials, including the early termination of the Cellulose Sulfate microbicide trial and two Phase IIb HIV vaccine trials (STEP and Phambili). The present study aimed to explore the perspectives and experiences of civil society organization (CSO) representatives regarding negative HIV prevention trial results and perceived implications for future trials. We conducted in-depth interviews with 14 respondents from a broad range of South African and international CSOs, and analyzed data using thematic analysis. CSO representatives reported disappointment in response to negative trial results, but acknowledged such outcomes as inherent to clinical research. Respondents indicated that in theory negative trial results seem likely to impact on willingness to participate in future trials, but that in practice people in South Africa have continued to volunteer. Negative trial results were described as having contributed to improving ethical standards, and to a re-evaluation of the scientific agenda. Such negative results were identified as potentially impacting on funding for trials and engagement activities. Our findings indicate that trial closures may be used constructively to support opportunities for reflection and renewed vigilance in strategies for stakeholder engagement, communicating trial outcomes, and building research literacy among communities; however, these strategies require sustained resources for community engagement and capacity-building.
AIDS Drug Assistance Programs in several states already have to put HIV-infected people on waiting lists to receive life-saving antiretroviral drugs because of budget shortfalls, and AIDS advocates say this problem will continue through 2002 and 2003 unless Congress provides a financial boost to HIV programs. Activists also say the United States will never achieve its goal of reducing new HIV infection rates by 50% within the next few years unless prevention spending is increased.

Young Latino immigrant men who have sex with men (MSM) are at risk for HIV and for delayed diagnosis. A need exists to raise awareness about HIV prevention in this population, including the benefits of timely HIV testing. This project was developed through collaboration between University of WA researchers and Entre Hermanos, a community-based organization serving Latinos. Building from a community-based participatory research approach, the researchers developed a campaign that was executed by Activate Brands, based in Denver, Colorado. The authors (a) describe the development of HIV prevention messages through the integration of previously collected formative data; (b) describe the process of translating these messages into PSAs, including the application of a marketing strategy; (c) describe testing the PSAs within the Latino MSM community; and (c) determine a set of important factors to consider when developing HIV prevention messages for young Latino MSM who do not identify as gay.

Renewed enthusiasm for biomedical HIV prevention strategies has followed the recent publication of several high-profile HIV antiretroviral therapy-based HIV prevention trials. In a recent article, Roberts & Matthews (2012) accurately note some of the shortcomings of these individually targeted approaches to HIV prevention and advocate for increased emphasis on structural interventions that have more fundamental effects on the population distribution of HIV. However, they make some implicit assumptions about the extent to which structural interventions are user-independent and more sustainable than biomedical or behavioral interventions. In this article, I elaborate a simple typology of structural interventions along these two axes and suggest that they may be neither user-independent nor sustainable and therefore subject to the same sustainability concerns, costs, and potential unintended consequences as biomedical and behavioral interventions.

HIV/AIDS is a global pandemic and is the leading infectious cause of death among adults. Although antiretroviral (ARV) therapy has dramatically improved the quality of life and increased the life expectancy of those infected with HIV, life-long suppressive treatment is required and a cure for HIV infection remains elusive; frequency of dosing and drug toxicity as well as the development of viral resistance pose additional limitations. Furthermore, preventative measures such as a vaccine or microbicide are urgently needed to curb the rate of new infections. The capabilities inherent to nanotechnology hold much potential for impact in the field of HIV treatment and prevention. This article reviews the potential for the multidisciplinary field of nanotechnology to advance the fields of HIV treatment and prevention.

Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show that transgender women sex workers (TSW) face unique structural, interpersonal, and individual vulnerabilities that contribute to risk for HIV. Only six studies of evidence-based prevention interventions were identified, none of which focused exclusively on TSW. We developed a deterministic model based on findings related to HIV risks and interventions. The model examines HIV prevention approaches in TSW in two settings (Lima, Peru and San Francisco, CA, USA) to identify which interventions would probably achieve the UN goal of 50% reduction in HIV incidence in 10 years. A combination of interventions that achieves small changes in behaviour and low coverage of biomedical interventions was promising in both settings, suggesting that the expansion of prevention services in TSW would be highly effective. However, this expansion needs appropriate sustainable interventions to tackle the upstream drivers of HIV risk and successfully reach this population. Case studies of six countries show context-specific issues that should inform development and implementation of key interventions across heterogeneous settings. We summarise the evidence and knowledge gaps that affect the HIV epidemic in TSW, and propose a research agenda to improve HIV services and policies for this population. PMID:25059941
The World Health Organization estimates that 50% of the 30 million HIV infections worldwide occurred in young people between the ages of 15 and 24 years. In the United States, national statistics estimate that almost 40% of new HIV cases occur in youth ages 13-29 (Centers for Disease Control and Prevention, 2011). Therefore, a focus on preventing…

In April 2008, the U.S. Centers for Disease Control and Prevention (CDC) hosted a national consultation meeting of academic researchers, public health officials, service providers, and community leaders to examine the HIV/AIDS epidemic and prevention needs of Hispanics/Latinos in the United States and its territories. The consultation engaged key stakeholders to review available information on HIV-related behavioral research and prevention efforts, describe gaps in current HIV prevention programs and research on Hispanics/Latinos, and identify community and societal-level factors that can increase vulnerability of Hispanics/Latinos for acquiring or transmitting HIV infection. Recommendations were also made to CDC for future collaboration with the Hispanic/Latino community in areas of HIV prevention research and prevention programs. This article summarizes participants' recommendations for HIV prevention research, program and capacity building, policy and planning, and partnerships and communication. These recommendations will be used by CDC to inform the development of a National Plan of Action for HIV/AIDS prevention among Hispanics/Latinos, and can provide a framework for use by other federal and non-federal agencies, academic researchers, community-based organizations, and policymakers as they seek to curtail the HIV epidemic among Hispanics/Latinos.

Objective The Enhanced Comprehensive HIV Prevention Planning project was the first initiative of the Centers for Disease Control and Prevention (CDC) to address the goals of the National HIV/AIDS Strategy (NHAS). Health departments in 12 U.S. cities with a high prevalence of AIDS conducted comprehensive program planning and implemented cost-effective, scalable HIV prevention interventions that targeted high-risk populations. We examined trends in health department HIV prevention programs in these cities during the project. Methods We analyzed the number of people who received partner services, condoms distributed, and people tested for HIV, as well as funding allocations for selected HIV prevention programs by year and by site from October 2010 through September 2013. We assessed trends in the proportional change in services and allocations during the project period using generalized estimating equations. We also conducted thematic coding of program activities that targeted people living with HIV infection (PLWH). Results We found significant increases in funding allocations for HIV testing and condom distribution. All HIV partner services indicators, condom distribution, and HIV testing of African American and Hispanic/Latino populations significantly increased. HIV tests associated with a new diagnosis increased significantly among those self-identifying as Hispanic/Latino but significantly decreased among African Americans. For programs targeting PLWH, health department activities included implementing new program models, improving local data use, and building local capacity to enhance linkage to HIV medical care, retention in care, and treatment adherence. Conclusions Overall, these findings indicate that health departments in areas with a high burden of AIDS successfully shifted their HIV prevention resources to scale up important HIV programs and make progress toward NHAS goals.

Broadly neutralizing monoclonal antibodies (nAbs) specific for HIV are being investigated for use in HIV prevention. Due to their ability to inhibit HIV attachment to and entry into target cells, nAbs may be suitable for use as topical HIV microbicides. As such, they would present an alternative intervention for individuals who may not benefit from using antiretroviral-based products for HIV prevention. We theorize that nAbs can inhibit viral transmission through mucosal tissue, thus reducing the incidence of HIV infection. The efficacy of the PG9, PG16, VRC01, and 4E10 antibodies was evaluated in an ex vivo human model of mucosal HIV transmission. nAbs reduced HIV transmission, causing 1.5- to 2-log10 reductions in HIV replication in ectocervical tissues and ≈3-log10 reductions in HIV replication in colonic tissues over 21 days. These antibodies demonstrated greater potency in colonic tissues, with a 50-fold higher dose being required to reduce transmission in ectocervical tissues. Importantly, nAbs retained their potency and reduced viral transmission in the presence of whole semen. No changes in tissue viability or immune activation were observed in colonic or ectocervical tissue after nAb exposure. Our data suggest that topically applied nAbs are safe and effective against HIV infection of mucosal tissue and support further development of nAbs as a topical microbicide that could be used for anal as well as vaginal protection.

The search for intervention strategies appropriate for young adolescents has recently led to the use of digital games. Digital gaming interventions are promising because they may be developmentally appropriate for adolescent populations. The gaming approach also capitalizes on an inherent interest to adolescents and circumvents traditional barriers to access to prevention interventions faced in some geographical areas. Notwithstanding, research on gaming in HIV prevention is quite limited. In this review article, we examine the need for contextually relevant HIV prevention interventions among young adolescents. From this, we provide a theoretical framework for exploring contextually relevant HIV risk factors and a foundation for gathering and using input from the target population to adapt an existing game or to create a developmentally appropriate and contextually relevant HIV prevention game.

Objectives. We examined HIV-infected parents’ conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. Methods. Parents with HIV/AIDS (n = 90) who had children aged 10 to 18 years were recruited for a mixed method study from 2009 to 2010. Interviews assessed facilitators and barriers to discussing HIV prevention. A questionnaire identified the frequency and content of conversations, parental confidence level, and perceived importance of discussing preventive topics. Results. Eighty-one percent of parents reported “sometimes” or “often” communicating about HIV prevention. A subset of parents found these conversations difficult; 44% indicated their desire for support. Facilitators to communication included utilizing support, focusing on the benefits of talking, and having a previous relationship with one’s child. Barriers to discussions included fear of negative consequences, living in denial, and lacking a parental role model who discussed safer sex. Parents varied as to how they believed their HIV status affected communication. Those who did not disclose their HIV status to their children reported less frequent communication; self-efficacy partially mediated this relationship. Conclusions. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents. PMID:23763390

Teen pregnancy remains a public health concern particularly among Latinos, whose pregnancy rate of 83.5 per 1000 girls constitutes one of the highest rates of teen pregnancy among all ethnic and racial groups in the United States. To enhance the effectiveness of interventions for diverse Latino populations in the US, it is crucial to assess the community's understanding of the etiology of the problem of adolescent pregnancy and to implement programs that reflect the local community's beliefs and preferences. We present findings from six focus groups held with parents (n = 18), teachers (n = 23) and school stakeholders (n = 8) regarding teen pregnancy prevention among Latino youth at a high school located in a large, Midwestern city. Two investigators analyzed data iteratively using a template organizing approach. A consensus emerged across the groups regarding content that emphasized respect for oneself and one's family, a focus on personal and shared responsibility in reproductive health behavior, information about the "realities" or consequences associated with engaging in sexual activity, and information about contraceptives. The strong request from participants to include a parental education component reflects the community's belief that parents play a crucial, protective role in the socialization and development of adolescent sexual behavior, a view that is supported by empirical research. Findings highlight the importance of involving local school communities in identifying adolescent pregnancy prevention strategies that are responsive to the community's cultural values, beliefs, and preferences, as well as the school's capacity and teacher preferences.

Introduction The remarkable expansion in availability of antiretroviral therapy (ART) over the past two decades has transformed HIV infection into a manageable chronic condition. People with HIV infection now live long and healthy lives on treatment that is simpler, safer and cheaper. According to UNAIDS estimates, the global coverage of ART reached 46% in 2015, resulting in a 26% decrease in annual HIV-related deaths since 2010. Such success has positioned treatment access at the centre of the global HIV response as a way to prevent mortality, morbidity and HIV transmission through a “Treat All” approach. Continuing expansion of treatment is needed to further reduce HIV-related mortality. This progress with treatment, however, masks a stagnation in the estimated annual number of new HIV infections. Continuing levels of HIV incidence despite treatment scale-up stem from several factors, which should be addressed in order to prevent new infections and decrease the numbers of people requiring treatment in the future. Discussion ART can only reach those already diagnosed, and although it is unclear what proportion of new infections occur during acute and early infection prior to treatment initiation, phylogenetic studies suggest that it might be substantial. Thus, better testing approaches to reach the 40% of people with undiagnosed HIV infection as early as possible are critical. New approaches to reach men, young people and key populations, where HIV risk is highest and HIV prevention, testing and treatment coverage is lowest, are also needed. Overall coverage of effective prevention interventions remains low, enabling HIV transmission to occur, or time is required to show population-level effects. For example, the full impact of the medical male circumcision intervention will be seen once a larger proportion of men in age cohorts with high incidence are circumcised. Finally, strategically focused pre-exposure prophylaxis interventions have the potential to

HIV-1 sequencing has been used extensively in epidemiologic and forensic studies to investigate patterns of HIV-1 transmission. However, the criteria for establishing genetic linkage between HIV-1 strains in HIV-1 prevention trials have not been formalized. The Partners in Prevention HSV/HIV Transmission Study (ClinicaITrials.gov NCT00194519) enrolled 3408 HIV-1 serodiscordant heterosexual African couples to determine the efficacy of genital herpes suppression with acyclovir in reducing HIV-1 transmission. The trial analysis required laboratory confirmation of HIV-1 linkage between enrolled partners in couples in which seroconversion occurred. Here we describe the process and results from HIV-1 sequencing studies used to perform transmission linkage determination in this clinical trial. Consensus Sanger sequencing of env (C2-V3-C3) and gag (p17-p24) genes was performed on plasma HIV-1 RNA from both partners within 3 months of seroconversion; env single molecule or pyrosequencing was also performed in some cases. For linkage, we required monophyletic clustering between HIV-1 sequences in the transmitting and seroconverting partners, and developed a Bayesian algorithm using genetic distances to evaluate the posterior probability of linkage of participants sequences. Adjudicators classified transmissions as linked, unlinked, or indeterminate. Among 151 seroconversion events, we found 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) to have indeterminate transmissions. Nine (8.3%) were linked by consensus gag sequencing only and 8 (7.4%) required deep sequencing of env. In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner, illustrating the relevance of these methods in the design of future HIV-1 prevention trials in serodiscordant couples. A hierarchy of sequencing techniques, analysis methods, and expert adjudication contributed to the linkage

Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

With HIV funding plateauing and the number of people living with HIV increasing due to the roll-out of life-saving antiretroviral therapy, policy makers are faced with increasingly tighter budgets to manage the ongoing HIV epidemic. Cost-effectiveness and modeling analyses can help determine which HIV interventions may be of best value. Incidence remains remarkably high in certain populations and countries, making prevention key to controlling the spread of HIV. This paper briefly reviews concepts in modeling and cost-effectiveness methodology, then examines results of recently published cost-effectiveness analyses on the following HIV prevention strategies: condoms and circumcision, behavioral or community-based interventions, prevention of mother to child transmission, HIV testing, pre-exposure prophylaxis, and treatment as prevention. We find that the majority of published studies demonstrate cost-effectiveness; however, not all interventions are affordable. We urge continued research on combination strategies and methodologies that take into account willingness to pay and budgetary impact. PMID:26830283

To be effective, HIV prevention programs should be planned in partnership with affected communities and should be built on a solid scientific foundation. In 1994, the Centers for Disease Control and Prevention (CDC) and its prevention partners implemented HIV prevention community planning to achieve primarily these two objectives. In order to manage the community planning process effectively, extensive evaluation activities were employed at both the grantee and national level. This paper describes the first year evaluation goals and methods in detail. Throughout, reasons for collecting specific types of information and for using particular methodologies are highlighted.

High rates of human immunodeficiency virus (HIV) infection among jail and prison inmates suggest that HIV prevention efforts should focus on incarcerated populations. Overcrowding, the high prevalence of injection drug use, and other high-risk behaviors among inmates create a prime opportunity for public health officials to affect the course of the HIV epidemic if they can remedy these problems. Yet, along with the opportunity, there are certain obstacles that correctional institutions present to public health efforts. The various jurisdictions have differing approaches to HIV prevention and control. Whether testing should be mandatory or voluntary, whether housing should be integrated or segregated by HIV serostatus, and whether condoms, bleach, or clean needles should be made available to the prisoners, are questions hotly debated by public health and correctional officials. Even accurate assessment of risk-taking within the institutions leads to controversy, as asking questions could imply acceptance of the very behaviors correctional officials are trying to prevent. Education and risk-reduction counseling are the least controversial and most widely employed modes of prevention, but the effectiveness of current prevention efforts in reducing HIV transmission in this high-risk population is largely undetermined.

HIV is transmitted through dyadic exchanges of individuals linked in transitory or permanent networks of varying sizes. To optimize prevention efficacy, a complementary theoretical perspective that bridges key individual level elements with important network elements can be a foundation for developing and implementing HIV interventions with outcomes that are more sustainable over time and have greater dissemination potential. Toward that end, we introduce a Network-Individual-Resource (NIR) model for HIV prevention that recognizes how exchanges of resources between individuals and their networks underlies and sustains HIV-risk behaviors. Individual behavior change for HIV prevention, then, may be dependent on increasing the supportiveness of that individual's relevant networks for such change. Among other implications, an NIR model predicts that the success of prevention efforts depends on whether the prevention efforts (1) prompt behavior changes that can be sustained by the resources the individual or their networks possess; (2) meet individual and network needs and are consistent with the individual's current situation/developmental stage; (3) are trusted and valued; and (4) target high HIV-prevalence networks.

HIV and sexually transmitted diseases (STDs) are major public health problems in the United States. Since the start of the epidemic, nearly 800,000 persons have been reported with AIDS, and approximately 900,000 Americans are currently living with HIV infection. Each year, 15 million people in the United States become infected with one or more STDs. The direct and indirect costs of the major STDs--not including HIV infection--and their complications are estimated to total at least $10 billion annually. This article underscores the importance of law and other structural factors in the prevention and treatment of HIV and STDs. It describes state-level laws on STD screening, name-based reporting of STDs, name-based reporting of HIV and HIV partner notification implementation, and the impact of laws on STD and HIV risk behaviors and prevention services. More broadly, the article focuses on how the law influences the vulnerability or resilience of persons facing the risk of STDs, HIV infection, or AIDS.

In 2002 MTV launched a global multicomponent HIV prevention campaign, "Staying Alive," reaching over 166 countries worldwide. An evaluation of this campaign focused on three diverse sites: Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal. Data were collected before and after campaign implementation through population-based household surveys. Using linear regression techniques, our evaluation examined the effects of campaign exposure on interpersonal communication about HIV and the effects of campaign exposure and interpersonal communication on beliefs about HIV prevention. We found a consistent positive effect of exposure on interpersonal communication across all sites, though there were differences among sites with regard to whom the respondent talked about HIV. We also found a consistent positive effect of exposure on HIV prevention beliefs across sites when interpersonal communication was simultaneously entered into the model. Finally, in two sites we found a relationship between interpersonal communication and HIV prevention beliefs, controlling for exposure, though again, the effects differed by the type of person the communication was with. These similar findings in three diverse sites provide ecological validity of the findings that "Staying Alive" promoted interpersonal communication and influenced young people's beliefs about HIV prevention in a positive way, evidence for the potential of a global media campaign to have an impact on social norms.

Worldwide, nearly half of all individuals living with HIV are now women, who acquire the virus largely by heterosexual exposure. With an HIV vaccine likely to be years away, topical microbicide formulations applied vaginally or rectally are being investigated as another strategy for HIV prevention. A review of preclinical and clinical research on the development of microbicides formulated to prevent vaginal HIV transmission yielded 118 studies: 73 preclinical and 45 clinical. Preclinical research included in-vitro assays and cervical explant models, as well as animal models. Clinical research included phase I and II/IIb safety studies, and phase III efficacy studies. Whereas most phase I and phase II clinical trials have found microbicide compounds to be safe and well tolerated, phase III trials completed to date have not demonstrated efficacy in preventing HIV transmission. Topical microbicides are grouped into five classes of agents, based on where they disrupt the pathway of sexual transmission of HIV. These classes include surfactants/membrane disruptors, vaginal milieu protectors, viral entry inhibitors, reverse transcriptase inhibitors, and a fifth group whose mechanism is unknown. The trajectory of microbicide development has been toward agents that block more specific virus—host cell interactions. Microbicide clinical trials face scientifically and ethically complex issues, such as the choice of placebo gel, the potential for viral resistance, and the inclusion of HIV-infected participants. Assessment of combination agents will most likely advance this field of research. PMID:18992405

Abstract An overall decrease of HIV prevalence is now observed in several key Asian countries due to effective prevention programs. The decrease in HIV prevalence and incidence may further improve with the scale-up of combination prevention interventions. The implementation of future prevention trials then faces important challenges. The opportunity to identify heterosexual populations at high risk such as female sex workers may rapidly wane. With unabating HIV epidemics among men who have sex with men (MSM) and transgender (TG) populations, an effective vaccine would likely be the only option to turn the epidemic. It is more likely that efficacy trials will occur among MSM and TG because their higher HIV incidence permits smaller and less costly trials. The constantly evolving patterns of HIV-1 diversity in the region suggest close monitoring of the molecular HIV epidemic in potential target populations for HIV vaccine efficacy trials. CRF01_AE remains predominant in southeast Asian countries and MSM populations in China. This relatively steady pattern is conducive to regional efficacy trials, and as efficacy warrants, to regional licensure. While vaccines inducing nonneutralizing antibodies have promise against HIV acquisition, vaccines designed to induce broadly neutralizing antibodies and cell-mediated immune responses of greater breadth and depth in the mucosal compartments should be considered for testing in MSM and TG. The rationale and design of efficacy trials of combination prevention modalities such as HIV vaccine and preexposure prophylaxis (PrEP) remain hypothetical, require high adherence to PrEP, are more costly, and present new regulatory challenges. The prioritization of prevention interventions should be driven by the HIV epidemic and decided by the country-specific health and regulatory authorities. Modeling the impact and cost–benefit may help this decision process. PMID:26107771

Media messages can facilitate the delivery of accurate information related to HIV and sexually transmitted infection. This study's purpose was to examine preexisting media campaigns from the iMPPACS study to assess age-, gender-, and culturally appropriate components identified by African American females who attend historically Black colleges/universities. In 3 separate focus group sessions, 31 Black female college students (M age = 20) viewed 4 vignettes and heard 3 audio-only clips, then ranked and commented on them based on perceived satisfaction with HIV prevention content and appropriateness of delivery. Conventional qualitative analysis using NVivo software was performed until saturation of content was achieved and themes derived. Six major themes emerged and were designated as (a) social media; (b) mirror image; (c) visually dynamic advertisements; (d) the real world; (e) people, place, things; and (f) HIV knowledge. Visually stimulating content (i.e., graphics) was found to be most appealing in marketing HIV prevention, with brief monologue/dialogue from scenarios that resemble daily life. Socially and culturally relevant HIV prevention messages are important to Black college female students. Participants recommended creating short audiovisual messages that encompass familiar contexts like dorm rooms and appealing graphics for HIV health promotion messages, such as emojis. Future audio-only prevention advertisements for this population should use recognizable voices (e.g., celebrities). Finally, messaging should be promoted on open and closed circuit social media platforms.

The HIV-AIDS remains a public health problem which disproportionally affects women. However, prevention strategies have rarely considered their specific efficacy for them. For this reason, this study examines the differential effectiveness of six intervention elements based on socio-cognitive theories addressing young women. A controlled between-groups design examined the change in risk profile among 167 young Spanish women (mean age 21.3 years old) involved in five sexual risk prevention interventions (informative talk, attitudinal discussion, role-play, fear induction and informative website) and one control non-intervening group (waiting list). Our findings support the differential efficacy of some HIV preventive intervention elements comparing others for women. In particular, the attitudinal discussion stands out followed by the informative talk and the role play. Contrarily, the fear induction component did not reveal relevant improvements. This study provides new evidence related to HIV prevention. Particularly, the higher efficacy of motivational components for these young Spanish women is revealed.

Networks of concurrent sexual partnerships may be the primary cause of epidemic spread of HIV-1 in parts of sub-Saharan Africa. This pattern of sexual behaviour increases the likelihood that individuals experiencing primary HIV-1 infection transmit the virus to other persons. Networks of concurrent partnerships are likely to be important in both the early ('epidemic') and late ('endemic') phases of HIV-1 transmission. Interventions should aim to break the sexual networks, whatever the stage of the epidemic. However, prevention of transmission in the endemic phase also requires a greater awareness of early clinical manifestations of HIV-1 infection in the general population. Such awareness, coupled with the availability of condoms and access to HIV-1 testing facilities, may reduce transmission in discordant couples.

The National HIV Behavioral Surveillance system (NHBS) was designed to monitor HIV prevalence and risk factors for infection among higher-risk individuals, i.e., sexually active men who have sex with men who attend venues, injection drug users who injected in the past 12 months, and heterosexuals living in low socioeconomic urban areas. These groups were selected as priorities for behavioral surveillance since they represent the major HIV transmission routes and the populations with the highest HIV burden. NHBS contributes to the nation's program of HIV surveillance by being the only multi-site population-based system that provides estimates on key HIV prevention measures among high-risk HIV-negative individuals, HIV-positive individuals unaware of their infection, and HIV-positive individuals aware of their infection who are in and out of care. Accurate and precise data on the behaviors in these populations are critical for tracking the epidemic, planning effective responses, and monitoring and evaluating those responses. Reports in this supplement illustrate the uses of NHBS data at the national and local level and reflect ongoing efforts to improve the system and remains essential for characterizing and monitoring the burden of HIV infection and sexual and behavioral risks.

The main research question in this article is how access to information about HIV/AIDS and level of HIV/AIDS prevention related knowledge are distributed among disabled people, and whether level of knowledge predicts access to HIV/AIDS related services. A survey was carried out among a sample of 285 disabled people from three provinces in South Africa. Analyses of the data revealed that gender and level of education, together with geographical differences, are key predictors for access to information and knowledge about HIV/AIDS among disabled people. For male respondents number of information sources predicts access to voluntary counselling and testing services and HIV testing, while knowledge about prevention predicts access to Voluntary Counselling and Testing centres. Significant gender differences with regards to information, knowledge and access to services highlight the need for gender specific prevention strategies among disabled people.

Importance The Human Immunodeficiency Virus (HIV) epidemic has evolved, with an increasing non-communicable disease (NCD) burden emerging and need for long-term management, yet there are limited data to help delineate the optimal care model to screen for NCDs for this patient population. Objective The primary aim was to compare rates of NCD preventive screening in persons living with HIV/AIDS (PLWHA) by type of HIV care model, focusing on metabolic/cardiovascular disease (CVD) and cancer screening. We hypothesized that primary care models that included generalists would have higher preventive screening rates. Design Prospective observational cohort study. Setting Partners HealthCare System (PHS) encompassing Brigham & Women’s Hospital, Massachusetts General Hospital, and affiliated community health centers. Participants PLWHA age >18 engaged in active primary care at PHS. Exposure HIV care model categorized as infectious disease (ID) providers only, generalist providers only, or ID plus generalist providers. Main Outcome(s) and Measures(s) Odds of screening for metabolic/CVD outcomes including hypertension (HTN), obesity, hyperlipidemia (HL), and diabetes (DM) and cancer including colorectal cancer (CRC), cervical cancer, and breast cancer. Results In a cohort of 1565 PLWHA, distribution by HIV care model was 875 ID (56%), 90 generalists (6%), and 600 ID plus generalists (38%). Patients in the generalist group had lower odds of viral suppression but similar CD4 counts and ART exposure as compared with ID and ID plus generalist groups. In analyses adjusting for sociodemographic and clinical covariates and clustering within provider, there were no significant differences in metabolic/CVD or cancer screening rates among the three HIV care models. Conclusions There were no notable differences in metabolic/CVD or cancer screening rates by HIV care model after adjusting for sociodemographic and clinical factors. These findings suggest that HIV patients receive similar

Objective To review the current state of knowledge on the prevention of sexual transmission of HIV in adolescents and to highlight existing gaps and priority areas for future research. Background A disproportionate burden of HIV infections falls on adolescents, a developmental stage marked by unique neural, biological, and social transition. Successful interventions are critical to prevent the spread of HIV in this vulnerable population. Methods We summarized the current state of research on HIV prevention in adolescents by providing examples of successful interventions and best practices, and highlighting current research gaps. Results Adolescent interventions fall into three main categories: biomedical, behavioral, and structural. The majority of current research has focused on individual behavior change, while promising biomedical and structural interventions have been largely understudied in adolescents. Combination prevention interventions may be particularly valuable to this group. Conclusions Adolescents have unique needs with respect to HIV prevention and, thus, interventions should be designed to most effectively reach this population with information and services that will be relevant to them.

The HIV Prevention Trials Network (HPTN) 052 study, which showed the effectiveness of antiretroviral treatment in reducing HIV transmission, has been hailed as a "game changer" in the fight against HIV, prompting calls for scaling up treatment as prevention (TasP). However, it is unclear how TasP can be financed, given flat-lining support for global HIV programs. We assess whether TasP is indeed a game changer or if comparable benefits are obtainable at similar or lower cost by increasing coverage of medical male circumcision (MMC) and antiretroviral treatment (ART) at CD4 <350/μL. We develop a new mathematical model and apply it to South Africa, finding that high ART coverage combined with high MMC coverage provides approximately the same HIV incidence reduction as TasP, for $5 billion less over 2009-2020. MMC outperforms ART significantly in cost per infection averted ($1,096 vs. $6,790) and performs comparably in cost per death averted ($5,198 vs. $5,604). TasP is substantially less cost effective at $8,375 per infection and $7,739 per death averted. The prevention benefits of HIV treatment are largely reaped with high ART coverage. The most cost-effective HIV prevention strategy is to expand MMC coverage and then scale up ART, but the most cost-effective HIV-mortality reduction strategy is to scale up MMC and ART jointly. TasP is cost effective by commonly used absolute benchmarks but it is far less cost effective than MMC and ART. Given South Africa's current annual ART spending, the $5 billion in savings offered by MMC and ART over TasP in the next decade, for similar health benefits, challenges the widely hailed status of TasP as a game changer.

Reducing new HIV infections in the United States requires allocating public resources to interventions that will have the greatest impact on reducing the number of new infections. We report on the organizational experience of a federal agency's efforts to align its HIV prevention resources to reflect the specific priorities of a five-year strategic plan that has as its goal a fifty percent reduction in the number of annual HIV infections nationwide. Structural and other impediments encountered during the alignment process, and the steps taken to minimize their impact are described, adding to the empirical data base of strategic planning experiences in the public sector.

This paper describes the development, content, and capabilities of the online Global HIV Archive (GHA). With the goal of facilitating widespread adaptation and appropriate use of efficacious HIV prevention programs throughout the globe, GHA has: first, expanded and updated the search for HIV prevention programs originating in low-resource countries; second, identified those meritorious HIV prevention programs meeting established efficacy criteria of technical merit, replicability, and positive outcomes; third, prepared both implementation and evaluation materials from the efficacious programs for public use; fourth, developed interactive wizards or capacity-building tools to facilitate appropriate program selection, implementation, and adaptation; and, fifth, made the efficacious programs and accompanying wizards available to health practitioners throughout the globe in both printed and online formats.

Human immunodeficiency virus (HIV) may be transmitted through either cell-free virions or leukocytes harboring intracellular HIV in bodily fluids. In recent years, the early initiation of combination antiretroviral therapy leading to virological suppression has resulted in decreased HIV transmission to uninfected partners. Additionally, the efficacy of primary chemoprophylaxis with oral or topical antiretroviral regimens containing tenofovir (with or without emtricitabine) has been demonstrated. However, the efficacy of these approaches may be compromised by suboptimal adherence, decreased drug concentrations in mucosal compartments in women, and genital inflammation. Furthermore, in vitro studies on the effects of tenofovir on cell-associated HIV transmission have produced conflicting results. Preclinical studies suggest that combination preventive approaches may be most effective in stopping the transmission of HIV after mucosal exposure. Since the development of antibodies were found to correlate with protection in the only effective HIV vaccine trial, the administration of preformed mucosal and systemic antibodies may inform the development of safe and effective antibody-based oral, topical, and/or systemic preexposure prophylaxis agents and provide guidance in the development of HIV vaccines that effectively block cell-associated HIV transmission.

The Centers for Disease Control and Prevention (CDC) Sexually Transmitted Disease (STD) Treatment Guidelines were last updated in 2006. To update the “Clinical Guide to Prevention Services” section of the 2010 CDC STD Treatment Guidelines, we reviewed the recent science with reference to interventions designed to prevent acquisition of STDs, including human immunodeficiency virus (HIV) infection. Major interval developments include (1) licensure and uptake of immunization against genital human papillomavirus, (2) validation of male circumcision as a potent prevention tool against acquisition of HIV and some other sexually transmitted infections (STIs), (3) failure of a promising HIV vaccine candidate to afford protection against HIV acquisition, (4) encouragement about the use of antiretroviral agents as preexposure prophylaxis to reduce risk of HIV and herpes simplex virus acquisition, (5) enhanced emphasis on expedited partner management and rescreening for persons infected with Chlamydia trachomatis and Neisseria gonorrhoeae, (6) recognition that behavioral interventions will be needed to address a new trend of sexually transmitted hepatitis C among men who have sex with men, and (7) the availability of a modified female condom. A range of preventive interventions is needed to reduce the risks of acquiring STI, including HIV infection, among sexually active people, and a flexible approach targeted to specific populations should integrate combinations of biomedical, behavioral, and structural interventions. These would ideally involve an array of prevention contexts, including (1) communications and practices among sexual partners, (2) transactions between individual clients and their healthcare providers, and (3) comprehensive population-level strategies for prioritizing prevention research, ensuring accurate outcome assessment, and formulating health policy.

The impetus for, and efforts in the past 20 years toward a women-initiated method for preventing sexual transmission of HIV has been previously well described. To date, four classes of topical agents categorized by mechanism of action as: surfactants, buffers, cell entry blockers and antiretroviral agents have undergone advanced clinical testing. Thus far, only coitally linked use of 1% tenofovir gel has demonstrated moderate effectiveness in preventing HIV and HSV-2 infection and has generated renewed hope for microbicide development. Studies of new antiviral agents, novel delivery mechanisms and combination/multipurpose products that address challenges of adherence and enhance the effectiveness of tenofovir gel are already underway to further enhance sexual and reproductive health needs of men and women and efforts to prevent HIV infection.

Objective To conduct a critical review of all HIV prevention intervention studies conducted with adolescents in juvenile justice settings to inform future intervention development. Method PubMed and PsycInfo database searches were conducted for peer-reviewed, published HIV prevention intervention studies with juvenile offenders. Results Sixteen studies were identified (N = 3,700 adolescents). Half of the projects utilized rigorous methodologies to determine intervention effect on behavior change, such as conducting a randomized controlled trial (n = 8). Nine studies reported behaviors at least 3 months post-intervention and five out of nine showed decreases in sexual risk behavior. Conclusions Several HIV prevention programs with juvenile offenders have led to sexual risk reduction, although effect sizes are modest. Most existing programs have neglected to address the impact of family, mental health, and substance use on HIV risk. More work is needed to develop evidence-based interventions that include HIV prevention strategies relevant and appropriate for the juvenile justice setting. PMID:19741021

Measures to prevent sexual mucosal transmission of human immunodeficiency virus (HIV)-1 are urgently needed to curb the growth of the acquired immunodeficiency syndrome (AIDS) pandemic and ultimately bring it to an end. Studies in animal models and acute HIV-1 infection reviewed here reveal potential viral vulnerabilities at the mucosal portal of entry in the earliest stages of infection that might be most effectively targeted by vaccines and microbicides, thereby preventing acquisition and averting systemic infection, CD4 T-cell depletion and pathologies that otherwise rapidly ensue.
Reducing the incidence of HIV infection continues to be a crucial public health priority in the United States, especially among populations at elevated risk such as men who have sex with men, transgender women, people who inject drugs, and racial and ethnic minority communities. Although most HIV prevention efforts to date have focused on changing risky behaviors, the past decade has yielded efficacious new biomedical technologies designed to prevent infection, such as the prophylactic use of antiretroviral drugs and the first indications of an efficacious vaccine. Access to prevention technologies will be a significant part of the next decade’s response to HIV, and advocates are mobilizing to achieve more widespread use of these interventions. These breakthroughs, however, arrive at a time of escalating healthcare costs; health insurance coverage therefore raises pressing new questions about priority-setting and the allocation of responsibility for public health. The goals of this Article are to identify legal challenges and potential solutions for expanding access to biomedical HIV prevention through health insurance coverage. This Article discusses the public policy implications of HIV prevention coverage decisions, assesses possible legal grounds on which insurers may initially deny coverage for these technologies, and evaluates the extent to which these denials may survive external and judicial review. Because several of these legal grounds may be persuasive, particularly denials on the basis of medical necessity, this Article also explores alternative strategies for financing biomedical HIV prevention efforts.

HIV Prevention Trials Network 052 demonstrated that antiretroviral therapy (ART) prevents HIV transmission in serodiscordant couples. HIV from index-partner pairs was analyzed to determine the genetic linkage status of partner infections. Forty-six infections were classified as linked, indicating that the index was the likely source of the partner's infection. Lack of viral suppression and higher index viral load were associated with linked infection. Eight linked infections were diagnosed after the index started ART: 4 near the time of ART initiation and 4 after ART failure. Linked infections were not observed when the index participant was stably suppressed on ART.

This study was a pilot investigation of the feasibility, acceptability, and effects of TRAIN (Transit to Russia AIDS Intervention with Newcomers) a three-session HIV preventive intervention for Tajik male labor migrants performed in transit. Sixty adult Tajik male labor migrants on the 5-day train ride from Dushanbe to Moscow were randomly assigned to either the intervention or a control condition. Each initially completed an in-person survey then another 3 days later (immediately postintervention), and participated in a cell phone survey three months later. All participants came to all intervention sessions, were satisfied with the program, and completed all postassessments. In comparison with the controls, the TRAIN group reported significant increases in condom use with sex workers and non-sex workers, condom knowledge, worry about HIV/AIDS, talking with persons about HIV/AIDS, talking with wife about HIV/AIDS, community activities, and religious activities. HIV/AIDS prevention performed in transit is feasible, accceptable, and potentially efficacious in diminishing HIV risk behaviors in labor migrants. PMID:21696244

Worldwide, HIV disproportionately affects women who are often unable to negotiate traditional HIV preventive strategies such as condoms. In the absence of an effective vaccine or cure, chemoprophylaxis may be a valuable self-initiated alternative. Topical microbicides have been investigated as one such option. The first generation topical microbicides were non-specific, broad-spectrum antimicrobial agents, including surfactants, polyanions, and acid buffering gels, that generally exhibited contraceptive properties. After extensive clinical study, none prevented HIV infection, and their development was abandoned. Second generation topical microbicides include agents with selective mechanisms of antiviral activity. Most are currently being used for, or have previously been explored as, drugs for treatment of HIV. The most advanced of these is tenofovir 1% gel: the first topical agent shown to significantly reduce HIV infection by 39% compared to placebo. This review summarizes the evolution of topical microbicides for HIV chemoprophylaxis, highlights important concepts learned, and offers current and future considerations for this area of research.

Thanks to very effective interventions vertical transmission of HIV has been reduced from over 20% ten years ago to less than 2% today in industrialised countries. This progress has been achieved by combined application of different strategies including antiretroviral treatment of pregnant women, elective caesarian section (prior to labour and rupture of membranes) and refraining from breastfeeding. Fortunately, the Swiss Mother & Child HIV Cohort Study (MoCHiV) has been able to support this evolution with several important contributions. Nevertheless the most important challenge in the prevention of vertical HIV transmission remains to be resolved in this decade. This impressive reduction in vertical transmission achieved in the industrialised world and delineated in this article still needs to be carried forward to those countries in the third world where HIV prevalence is much higher and interventions therefore much more needed.

Among the most frequently asked questions by callers to the National Perinatal HIV Hotline are those on the use of hormonal contraception in women receiving antiretroviral therapy. Estradiol levels are reduced by ritonavir-boosted protease inhibitors (PIs), nelfinavir, and nevirapine and increased by non-ritonavir-boosted PIs (except nelfinavir), efavirenz, and etravirine. Oral contraceptives do not affect antiretroviral drug levels, and several options are available for hormonal contraception that can compensate for or avoid the effects of antiretroviral drugs on estrogen levels. Other common questions on the hotline involve interpretation and management issues that arise from indeterminate Western blot test results early and late in pregnancy and from positive rapid test results during labor. Many questions focus on appropriate selection of antiretroviral drugs in pregnancy and the need to change regimens to reduce risk of birth defects in the child. This articlesummarizes a presentation by Jess Fogler Waldura, MD, at the 13th Annual Clinical Conference for the Ryan White HIV/AIDS Program held in August 2010 in Washington, DC.

The number of new HIV-1 infections remains stable in Switzerland over the last years thanks to the effective prevention programs. However, the aim to halve the new HIV infection rate has not been reached. Early identification of patients at risk of acquiring HIV infection and counselling "safer sex" rules as well as treating HIV-infected patients plays a decisive role in this program. Studies are -ongoing to investigate additional preventive measures such as pre-exposure prophylaxis, microbicides and vaccines, but none of those approaches permit omitting "safer sex". Incidences of other sexual transmitted infections are increasing rapidly, in particular the incidence of Syphilis. Transmission occurs more often orally or rectally than vaginally and patients are often asymptomatic. Condoms provide only limited protection. In addition antibiotic resistance emerges complicating the therapy, as for example for gonorrhea. Testing and treatment of infected patients is primordial as well as contact tracing. In this work, we discuss the different elements for preventing STIs with major emphasis on HIV.

The 2016 Conference on Retroviruses and Opportunistic Infections (CROI) highlighted hot spots in HIV infection. Men who have sex with men (MSM), transgender populations, people who inject drugs, fisherfolk, migrants, adolescents, and older adults are heavily impacted in a number of regions. Stigma contributes to risk behaviors and HIV acquisition across populations. HIV testing is a crucial first step in the HIV care continuum, and several large community-based surveys are underway in Africa to increase HIV testing, linkage to care, and uptake of antiretroviral treatment. Advances in preexposure prophylaxis (PrEP) featured prominently at CROI 2016. Two large efficacy trials of a vaginal ring containing the investigational drug dapivirine demonstrated efficacy and safety in preventing HIV infections in women in Africa. Data on the safety of long-acting injectable PrEP and several investigational PrEP drugs and formulations were also presented. Knowledge and use of PrEP among MSM in the United States appears to be increasing, and high uptake was seen among black MSM when provided as part of a culturally tailored support program. The use of broadly neutralizing antibodies for HIV prevention is a novel and promising approach to be evaluated in efficacy trials.

Australia has not seen a Human Immunodeficiency Virus (HIV) epidemic among young people. However, early research in the Australian context had indicated that the degree of unprotected sexual activity, partner change, and STI infection in this cohort would fuel a young people's epidemic if HIV ever reached a tipping point in the country. The difficulty of reaching young people outside school for HIV prevention has been no more successfully addressed in Australia than elsewhere. Therefore, the investment of Australian HIV prevention funds for youth has had an emphasis on school-based programs. This emphasis on formal schooling has led to a history of engagement with the ad hoc and unreliable nature of sexuality education in Australian schools. It has particularly been the catalyst for a struggle to construct young people as sexually active and as possessing a right to appropriate education, against tides of both secular and religiously-motivated resistance. The eight state and territory education sectors, along with the independent sectors, have had differing and sometimes troubled histories with HIV prevention. This paper discusses the differing HIV education policies and programs that have emerged in Australian schooling historically, and in some cases been abandoned altogether, amid strong public debates. It also considers current approaches, the new national curriculum, and future challenges. Additionally, the particular case of same sex attracted young men, who have a heightened level of vulnerability to HIV, is explored. Australian schools have struggled to address both the imperative for relevant sexuality education for same-sex-attracted young people and the broader issue of combating homophobia, which research has linked directly to this vulnerability.

This article reviews the epidemiology of perinatal (HIV)-1 in the United States in the past 2 decades and the international HIV epidemic among pregnant women and their infants. Since the peak of 1700 reported cases of pediatric AIDS in 1992, there has been dramatic progress in decreasing perinatal HIV transmission in the United States with fewer than 50 new cases of AIDS annually (>96% reduction) and fewer than 300 annual perinatal HIV transmissions in 2005. This success has been due to use of combination antiretrovirals given to mothers during pregnancy and labor/delivery, obstetric interventions that reduce the risk of transmission, provision of zidovudine (ZDV) prophylaxis for 6 weeks to HIV-exposed newborns and use of formula. Internationally, the burden of mother-to-child HIV transmission remains heavy with 2.1 million children less than 15 years of age estimated to be living with HIV and 430,000 new HIV infections in infants occurring each year, with most cases occurring in Africa. Current international efforts are directed at scaling up successful prevention of mother-to-child transmission interventions and new research directed at making breastfeeding safer using antiretroviral prophylaxis to either mothers or their infants.
This paper examines the ways in which HIV prevention is understood including "biomedical", "behavioural", "structural", and "combination" prevention. In it I argue that effective prevention entails developing community capacity and requires that public health addresses people not only as individuals but also as connected members of groups, networks and collectives who interact (talk, negotiate, have sex, use drugs, etc.) together. I also examine the evaluation of prevention programmes or interventions and argue that the distinction between efficacy and effectiveness is often glossed and that, while efficacy can be evaluated by randomized controlled trials, the evaluation of effectiveness requires long-term descriptive strategies and/or modelling. Using examples from a number of countries, including a detailed account of the Australian HIV prevention response, effectiveness is shown to be dependent not only on the efficacy of the prevention technology or tool but also on the responses of people - individuals, communities and governments - to those technologies. Whether a particular HIV prevention technology is adopted and its use sustained depends on a range of social, cultural and political factors. The paper concludes by calling on biomedical and social scientists to work together and describes a "social public health".

In 2015, the publication of important studies allowed the development of new guidelines, notably by WHO and the European AIDS ClinicalSociety (EACS), for HIV preventive treatment (pre-exposure prophylaxis), as well as for the start of antiretroviral treatment. The START and TEMPRANO studies have extended the treatment to all HIV-infected patients, irrespective of the level of immunosuppression and therefore the CD4 count. In addition, innovative screening methods, such as self-tests, are now available in all French pharmacies since 15 September 2015. The latest developments in 2015 concerning the prevention, screening, and treatment of HIV are discussed in this article and will certainly have an impact on the care of patients in Switzerland.
The Female Health Co. (FHC), London, United Kingdom, has signed a three-year agreement with the Joint United Nations Program on HIV/AIDS (UNAIDS) to provide a global public sector price for the female condom to 193 affiliated countries. An adjunct education and social marketing program, supported by UNAIDS, will be launched. High rates of acceptance have been shown previously when the female condom has been introduced with an effective educational approach. Negotiations between FHC and UNAIDS began in September 1996; 80 of 193 countries, upon inquiry, have already identified a requirement for over 7 million female condoms in 1997. UNAIDS estimates that nearly 50% of new human immunodeficiency virus (HIV) infections are in women; the female condom is the only woman-controlled product providing protection against sexually transmitted diseases (STDs), including HIV and acquired immunodeficiency syndrome (AIDS). Studies have indicated that the number of unprotected sex acts decreases when the female condom is available. Dr. Peter Piot (UNAIDS) states that the female condom is important in those cultures and situations where women have limited control over sexual decisions. Dr. Mary Ann Leeper (FHC) states that the company is committed to making the female condom available in developing countries.
Every day, more than 1 million people are newly infected with sexually transmitted infections (STIs) that can lead to morbidity, mortality, and an increased risk of human immunodeficiency virus (HIV) acquisition. Existing prevention and management strategies, including behavior change, condom promotion, and therapy have not reduced the global incidence and prevalence, pointing to the need for novel innovative strategies. This review summarizes important issues raised during a satellite session at the first HIV R4P conference, held in Cape Town, on October 31, 2014. We explore key STIs that are challenging public health today; new biomedical prevention approaches including multipurpose prevention technologies (MPTs); and the scientific and regulatory hurdles that must be overcome to make combination prevention tools a reality.

Purpose To explore the feasibility of engaging community businesses in HIV prevention. Design Randomly selected business owners/managers were asked to display discreetly wrapped condoms and brochures provided free-of-charge for 3 months. Assessments were conducted at baseline, mid-, and post-program. Customer feedback was obtained through an online survey. Setting San Diego, California neighborhood with a high rate of AIDS. Subjects Fifty-one business owners/managers representing 10 retail categories, and 52 customers. Measures Participation rates, descriptive characteristics, number of condoms and brochures distributed, customer feedback, business owners'/managers' program satisfaction and willingness to provide future support for HIV prevention. Analysis Kruskal-Wallis, Mann-Whitney U, Fisher's exact, and McNemar's tests were used to analyze data. Results The 20 business owners/managers (39%) who agreed to distribute condoms and brochures reported fewer years in business and more employees than those who agreed only to distribute brochures (20%) or refused to participate (41%), p <.05. Bars were the easiest of ten retail categories to recruit. Businesses with more employees and customers distributed more condoms and brochures, p < .05. More than 90% of customers supported distributing condoms and brochures in businesses and 96% of business owners/managers described their program experience as “positive.” Conclusion Businesses are willing to distribute condoms and brochures to prevent HIV. Policies to increase business participation in HIV prevention should be developed and tested. PMID:20465150

Black men who have sex with men (BMSM) bear an increasingly disproportionate burden of HIV in the United States. The Centers for Disease Control and Prevention recommends high-impact combination prevention for populations at high risk for HIV infection, such as BMSM. However, few scholars have considered the types of behavioral interventions that combined with biomedical prevention could prove effective for mitigating the epidemic among BMSM. Between June 2013 and May 2014, we conducted three in-depth interviews each with 31 BMSM, interviews with 17 community stakeholders, and participant observation in New York City to understand the sociocultural and structural factors that may affect the acceptance of and adherence to oral preexposure prophylaxis among BMSM and to inform an adherence clinical trial. BMSM and community leaders frequently described condomless sex as a consequence of psychosocial factors and economic circumstances stemming from internalized homophobia resulting from rejection by families and religious groups. BMSM revealed that internalized homophobia and HIV stigma resulted in perceived lack of self- and community efficacy in accepting and adhering to preexposure prophylaxis. Our results indicate that addressing internalized homophobia and fostering emotional social support in peer networks are key elements to improve the effectiveness of combination prevention among BMSM.

Internet-based interventions have potential to reduce HIV and STD transmission among men who meet male sexual partners online. From November 2009 to May 2010 we surveyed dating and hook-up website users (n=3,050), website owners (n=18), and health department HIV/STD directors (n=81) to identify structural and behavioral prevention interventions that could be implemented online and which a majority of website users were willing to use, owners were willing to implement, andHIV/STD directors perceived to beeffective. A majority of each of the three stakeholder groups agreed on the following: 1) automated HIV/STD testing reminders; 2) local STD test site directories; 3) links to sex-positive safe sex videos; 4) access to sexual health experts; 5) profile options to include safer sex preference; 6) chat rooms for specific sexual interests; 7) filtering partners by their profile information; and 8) anonymous e-card partner notification for STD exposure. Findings help build consensus about how to prioritize resources for implementing online HIV and STD prevention interventions and highlight differences between stakeholders to guide future discussion about how to advance prevention efforts.

This article explores how notions of the individual and population are evoked in two ongoing HIV treatment as prevention (TasP) implementation studies in Swaziland. By contrasting policy discourses with lived kinship experiences of people living with HIV, we seek to understand how TasP unfolds in the Swazi context. Data collection consisted of eight focus group discussions with people living with HIV who were members of support groups to examine their perspectives about TasP. In addition, 18 key informant interviews were conducted with study team members, national-level policy-makers and NGO representatives involved in the design of health communication messages about TasP in Swaziland. Thematic analysis was used to identify recurrent themes in transcripts and field notes. Policy-makers and people living with HIV actively resisted framing HIV treatment as a prevention technology but promoted it as (earlier) access to treatment for all. TasP was not conceptualised in terms of individual or societal benefits, which are characteristic of international public health debates; rather its locally situated meanings were embedded in kinship experiences, concerns about taking responsibility for one's own health and others, local biomedical knowledge about drug resistance, and secrecy. The findings from this study suggest that more attention is needed to understand how the global discourse of TasP becomes shaped in practice in different cultural contexts.
HIV infection is the greatest health crisis in human history. It continues to spread unchecked among the poor in the developing world because we have failed to design simple preventative methods that are available and affordable to those living on under $2 a day. Five new methods are discussed. (i) A natural microbicide. Intravaginal lime or lemon juice has been used for centuries as a traditional contraceptive. The juice can also kill HIV in the laboratory, but clinical trials are needed to see if vaginal application is acceptable, safe and effective. (ii) Intravaginal oestrogen. Monkeys can be protected from Simian immunodeficiency virus (SIV) infection by keratinizing the vagina with topical oestrogen. If women take the oral contraceptive pill vaginally it retains its contraceptive efficacy, and the oestrogen it contains should thicken the vagina and protect against HIV infection. Clinical trials are needed. (iii) Male circumcision. Removal of the inner foreskin removes the main site of HIV entry into the penis, resulting in a sevenfold reduction in susceptibility to infection. The practice needs to be promoted. (iv) Post-coital penile hygiene. Wiping the penis immediately after intercourse with lime or lemon juice or vinegar should kill the virus before it has had a chance to infect. A clinical trial of efficacy is needed. (v) PhotoVoice. Asking schoolchildren in developing countries to photograph their impressions of HIV/AIDS is a powerful way of getting them to discuss the subject openly, and develop their own preventative strategies.

Planning an intervention to prevent infections with the human immunodeficiency virus (HIV) should be guided by local epidemiological and socioeconomic conditions. The socioeconomic setting and existing public service capacity determine whether an intervention can have a significant outcome in terms of a reduction in a defined risk. The epidemiological context determines whether such risk reduction translates into a measurable impact on HIV incidence. Measurement of variables describing the epidemiological context can be used to determine the local suitability of interventions, thereby guiding planners and policy-makers in their choice of intervention. Such measurements also permit the retrospective analysis of the impact of interventions where HIV incidence was not recorded. The epidemiological context is defined for four different categories of intervention, shown to be effective in lower-income countries by randomized controlled trials. Appropriate indicators for the epidemiological context and methodological guidelines for their measurement are proposed. Their use in the transfer of a successful intervention from one context to another and in scaling up the effort to control HIV infection is explored. These indicators should provide a useful resource for those involved in planning HIV prevention interventions. PMID:11799444

Barriers and facilitators to pre-exposure prophylaxis (PrEP) eligibility screening and ongoing HIV testing among target populations in Bondo and Rarieda, Kenya: Results of a consultation with community stakeholders
Background As pre-exposure prophylaxis (PrEP) moves closer to availability in developing countries, practical considerations for implementation become important. We conducted a consultation with district-level community stakeholders experienced in HIV-prevention interventions with at-risk populations in Bondo and Rarieda, Kenya to generate locally grounded approaches to the future rollout of oral PrEP to four populations: fishermen, widows, female sex workers, and serodiscordant couples. Methods The 20 consultation participants represented the Ministry of Health, faith- and community-based organizations, health facilities, community groups, and nongovernmental organizations. Participants divided into breakout groups and followed a structured discussion guide asking them to identify barriers to implementing HIV-prevention interventions (including PrEP) with each population. Questions also solicited solutions for addressing these barriers, as well as other facilitators for PrEP implementation. In particular, questions focused on how to encourage people to screen for PrEP eligibility by having HIV and other blood tests and how to encourage compliance with ongoing HIV testing. Results The barriers and facilitators/solutions discussants provided were frequently population-specific, but there were also broad-level similarities across populations. Service delivery barriers to HIV-prevention interventions concerned the need for staff trained to address the needs of particular populations. Service delivery facilitators to provision of ongoing HIV testing consisted of offering testing options besides facility-based testing. Stigma was the main community-level barrier for all groups, whereas barriers at the level of target populations included mobility; lifestyle and life circumstances, especially cultural norms among fishermen and widows; and fears, lack of awareness, and misinformation. Proposed facilitators and strategies for addressing community- and population

This article aims to consider some relevant challenges to the provision of "new prevention technologies" in health services in a scenario where the "advances" in the global response to AIDS control are visible. We take as material for analysis the information currently available on the HIV post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), treatment as prevention (TASP) and over the counter. The methodology consisted of the survey and analysis of the Biblioteca Virtual em Saúde (BVS: MEDLINE, LILACS, WHOLIS, PAHO, SciELO) articles that addressed the issue of HIV prevention and care in the context of so-called new prevention technologies. The results of the studies show that there is assistance on the ground of clinics for the treatment of disease responses, but there are several challenges related to the sphere of prevention. The articles list some challenges regarding to management, organization of services and the attention given by health professionals to users. The current context shows evidence of the effectiveness of antiretroviral therapy in reducing the risk of HIV transmission, but the challenges for the provision of preventive technologies in health services permeate health professionals and users in their individual dimensions and health services in organizational and structural dimension. Interventions should be made available in a context of community mobilization; there should be no pressure on people to make HIV testing, antiretroviral treatment or for prevention. In the management is responsible for the training of health professionals to inform, clarify and make available to users, partners and family information about the new antiretroviral use strategies.

BACKGROUND An interim analysis of data from the HIV Prevention Trials Network (HPTN) 052 trial showed that antiretroviral therapy (ART) prevented more than 96% of genetically linked infections caused by human immunodeficiency virus type 1 (HIV-1) in serodiscordant couples. ART was then offered to all patients with HIV-1 infection (index participants). The study included more than 5 years of follow-up to assess the durability of such therapy for the prevention of HIV-1 transmission. METHODS We randomly assigned 1763 index participants to receive either early or delayed ART. In the early-ART group, 886 participants started therapy at enrollment (CD4+ count, 350 to 550 cells per cubic millimeter). In the delayed-ART group, 877 participants started therapy after two consecutive CD4+ counts fell below 250 cells per cubic millimeter or if an illness indicative of the acquired immunodeficiency syndrome (i.e., an AIDS-defining illness) developed. The primary study end point was the diagnosis of genetically linked HIV-1 infection in the previously HIV-1– negative partner in an intention-to-treat analysis. RESULTS Index participants were followed for 10,031 person-years; partners were followed for 8509 person-years. Among partners, 78 HIV-1 infections were observed during the trial (annual incidence, 0.9%; 95% confidence interval [CI], 0.7 to 1.1). Viral-linkage status was determined for 72 (92%) of the partner infections. Of these infections, 46 were linked (3 in the early-ART group and 43 in the delayed-ART group; incidence, 0.5%; 95% CI, 0.4 to 0.7) and 26 were unlinked (14 in the early-ART group and 12 in the delayed-ART group; incidence, 0.3%; 95% CI, 0.2 to 0.4). Early ART was associated with a 93% lower risk of linked partner infection than was delayed ART (hazard ratio, 0.07; 95% CI, 0.02 to 0.22). No linked infections were observed when HIV-1 infection was stably suppressed by ART in the index participant. CONCLUSIONS The early initiation of ART led to a sustained

Abstract In the United States, women are a significant proportion of the correctional population. Women also account for an increasing proportion of newly diagnosed human immunodeficiency virus (HIV) cases. When compared with white women, black women have higher incarceration rates and represent more of the newly diagnosed HIV cases. Correctional facilities offer an opportunity to provide women with HIV testing and prevention services so that they will know their status and receive HIV/sexually transmitted disease (STD) risk-reduction counseling and other preventive services. In this report, we describe incarcerated population statistics and HIV surveillance epidemiology for women. We also describe HIV prevention activities undertaken by the Centers for Disease Control and Prevention's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. Additional research, program development, and implementation are needed to improve HIV prevention efforts for high-risk women. PMID:24116966

HIV prevention interventions can help college students engage in safe sexual behaviors. We used the Information, Motivation, Behavioral Skills model to frame four focus group discussions with Black women (n = 32) attending a historically Black college/university or a traditional university to understand their HIV prevention needs. Participants wanted clear information about sexually transmitted infections/HIV and access to contraception. Motivators for practicing safe sex were related to cultural and religious expectations, desire to avoid pregnancy, and conscious efforts to defy racial stereotypes. Barriers to practicing safe sex included issues of accountability, stigma associated with accessing HIV testing/prevention services, and media influences. We found general consensus about the need to develop skill-building HIV prevention interventions focused on communication skills, condom negotiation, access to services, and empowerment. We offer insight into culture- and age-appropriate HIV prevention for Black college women to guide the development of future interventions.

This special issue of the Journal of Empirical Research on Human Research Ethics represents a sampling of projects fostered through the NIDA-funded Fordham University HIV Prevention Research Ethics Institute. The first three articles employ processes of co-learning to give voice to the experiences of individuals recovering from substance abuse and engaged in sex work who have participated in HIV prevention studies in the United States, India, and the Philippines. The fourth article describes a unique community-based approach to the development of research ethics training modules designed to increase participation of American Indian and Alaskan Native (AI/AN) tribal members as partners in research on health disparities. The last two articles focus a critical scholarly lens on two underexamined areas confronting IRB review of HIV research: The emerging and continuously changing ethical challenges of using social media sites for recruitment into HIV prevention research, and the handling of research-related complaints from participants involving perceived research harms or research experiences that do not accord with their initial expectations. Together, the articles in this special issue identify key ethical crossroads and provide suggestions for best practices that respect the values and merit the trust of research participants.

Introduction Social protection is high on the HIV-prevention agenda for youth in sub-Saharan Africa. However, questions remain: How do unconditional cash transfers work? What is the effect of augmenting cash provision with social care? And can “cash plus care” social protection reduce risks for adolescents most vulnerable to infection? This study tackles these questions by first identifying mediated pathways to adolescent HIV risks and then examining potential main and moderating effects of social protection in South Africa. Methods This study was a prospective observational study of 3515 10-to-17-year-olds (56.7% female; 96.8% one-year retention). Within randomly selected census areas in four rural and urban districts in two South African provinces, all homes with a resident adolescent were sampled between 2009/2010 and 2011/2012. Measures included 1) potential structural drivers of HIV infection such as poverty and community violence; 2) HIV risk behaviours; 3) hypothesized psychosocial mediating factors; and 4) types of social protection involving cash and care. Using gender-disaggregated analyses, longitudinal mediation models were tested for potential main and moderating effects of social protection. Results Structural drivers were associated with increased onset of adolescent HIV risk behaviour (p<0.001, B=0.06, SE=0.01), fully mediated by increased psychosocial problems. Both cash and care aspects of social protection were associated with reductions in HIV risk behaviour and psychosocial deprivations. In addition, cash social protection moderated risk pathways: for adolescent girls and boys experiencing more acute structural deprivation, social protection had the greatest associations with HIV risk prevention (e.g. moderation effects for girls: B=−0.08, p<0.002 between structural deprivation and psychosocial problems, and B=−0.07, p<0.001 between psychosocial problems and HIV risk behaviour). Conclusions Adolescents with the greatest structural
Reducing the incidence of HIV infection continues to be a crucial public health priority in the United States, especially among populations at elevated risk such as men who have sex with men, transgender women, people who inject drugs, and racial and ethnic minority communities. Although most HIV prevention efforts to date have focused on changing risky behaviors, the past decade yielded efficacious new biomedical technologies designed to prevent infection, such as the prophylactic use of antiretroviral drugs and the first indications of an efficacious vaccine. Access to prevention technologies will be a significant part of the next decade's response to HIV and advocates are mobilizing to achieve more widespread use of these interventions. These breakthroughs, however, arrive at a time of escalating healthcare costs; health insurance coverage therefore raises pressing new questions about priority-setting and the allocation of responsibility for public health. The goals of this Article are to identify legal challenges and potential solutions for expanding access to biomedical HIV prevention through health insurance coverage. This Article discusses the public policy implications of HIVprevention coverage decisions, assesses possible legal grounds on which insurers may initially deny coverage for these technologies, and evaluates the extent to which these denials may survive external and judicial review. Because several of these legal grounds may be persuasive, particularly denials on the basis of medical necessity, this Article also explores alternative strategies for financing biomedical HIV prevention efforts.

The sex industry, where men sell sexual services to other men or women, has grown in recent years. These men who offer sexual services are particularly vulnerable to HIV infection due to such factors as: frequency of risky sexual practices, number of sex partners, drug-taking, prevalence of sexually-transmitted infections (STI) and their specific situation of social exclusion which may hinder access to health services. These multi-faceted realities faced by sex workers explain the burgeoning interest in new avenues of scientific research. There are too few preventive programs however aimed at this population group and the studies that evaluate their effectiveness are fewer still. In this article we survey more recent studies on the difficulties of implementing programs for HIV prevention in male sex workers (MSW), as well as the studies that have gauged the impact of preventive programs in this group.
This paper compares policies on named HIV testing in the context of HIV prevention in Britain, Hungary and Sweden, and considers the extent to which these policies are based on evidence of effectiveness or on other, more contextual, factors. In Britain, testing has not featured significantly as a prevention strategy, and named testing has generally been carried out only with the voluntary, informed consent of individuals. In Hungary, testing is central to HIV prevention, and is required by law of certain groups. HIV testing is carried out mainly on a voluntary basis in Sweden, but, unlike in Britain, it has been actively promoted by public health authorities. The paper contrasts the 'right not to know' one's HIV status which is widely respected in Britain, with the 'responsibility to find out' which is more pervasive in Hungary and Sweden. Although policy makers in all three countries appear convinced that their's is the right approach, there appears to be as yet a dearth of convincing evidence to support their arguments.

Introduction Treatment as prevention has mobilized new opportunities in preventing HIV transmission and has led to bold new UNAIDS targets in testing, treatment coverage and transmission reduction. These will require not only an increase in investment but also a deeper understanding of the dynamics of combining behavioural, biomedical and structural HIV prevention interventions. High-income countries are making substantial investments in combination HIV prevention, but is this investment leading to a deeper understanding of how to combine interventions? The combining of interventions involves complexity, with many strategies interacting with non-linear and multiplying rather than additive effects. Discussion Drawing on a recent scoping study of the published research evidence in HIV prevention in high-income countries, this paper argues that there is a gap between the evidence currently available and the evidence needed to guide the achieving of these bold targets. The emphasis of HIV prevention intervention research continues to look at one intervention at a time in isolation from its interactions with other interventions, the community and the socio-political context of their implementation. To understand and evaluate the role of a combination of interventions, we need to understand not only what works, but in what circumstances, what role the parts need to play in their relationship with each other, when the combination needs to adapt and identify emergent effects of any resulting synergies. There is little development of evidence-based indicators on how interventions in combination should achieve that strategic advantage and synergy. This commentary discusses the implications of this ongoing situation for future research and the required investment in partnership. We suggest that systems science approaches, which are being increasingly applied in other areas of public health, could provide an expanded vocabulary and analytic tools for understanding these

HIV/AIDS infections are growing at an alarming rate for young adults. In 2009, youth, ages 13-29, accounted for 39% of all new HIV infections in the U.S. (Division of HIV/ AIDS Prevention, Centers for Disease Control (CDC), 2011). South Carolina ranks eighth in the nation for new HIV cases, while the capital city of Columbia ranks seventh…

Despite advances in HIV prevention and care, African Americans and Latino Americans remain at much higher risk of acquiring HIV, are more likely to be unaware of their HIV-positive status, are less likely to be linked to and retained in care, and are less likely to have suppressed viral load than are Whites. The first National HIV/AIDS Strategy…

The development of pharmaceutical HIV prevention technologies (PPTs) over the last five years has generated intense interest from a range of stakeholders. There are concerns that these clinical and pharmaceutical interventions are proceeding with insufficient input of the social sciences. Hence key questions around implementation and evaluation remain unexplored whilst biomedical HIV prevention remains insufficiently critiqued or theorised from sociological as well as other social science perspectives. This paper presents the results of an expert symposium held in the UK to explore and build consensus on the role of the social sciences in researching and evaluating PPTs in this context. The symposium brought together UK social scientists from a variety of backgrounds. A position paper was produced and distributed in advance of the symposium and revised in the light this consultation phase. These exchanges and the emerging structure of this paper formed the basis for symposium panel presentations and break-out sessions. Recordings of all sessions were used to further refine the document which was also redrafted in light of ongoing comments from symposium participants. Six domains of enquiry for the social sciences were identified and discussed: self, identity and personal narrative; intimacy, risk and sex; communities, resistance and activism; systems, structures and institutions; economic considerations and analyses; and evaluation and outcomes. These are discussed in depth alongside overarching consensus points for social science research in this area as it moves forward.

This paper will explore in detail the effects of context and group dynamics on the development of a multi-level community-based HIV prevention intervention for crack cocaine users in the San Salvador Metropolitan Area, El Salvador. Community partners included residents from marginal communities, service providers from the historic center of San Salvador and research staff from a non-profit organization. The community contexts from which partners came varied considerably and affected structural group dynamics, i.e. who was identified as community partners, their research and organizational capacity, and their ability to represent their communities, with participants from marginal communities most likely to hold community leadership positions and be residents, and those from the center of San Salvador most likely to work in religious organizations dedicated to HIV prevention or feeding indigent drug users. These differences also affected the intervention priorities of different partners. The context of communities changed over time, particularly levels of violence, and affected group dynamics and the intervention developed. Finally, strategies were needed to elicit input from stakeholders under-represented in the community advisory board, in particular active crack users, in order to check the feasibility of the proposed intervention and revise it as necessary. Because El Salvador is a very different context than that in which most CBPR studies have been conducted, our results reveal important contextual factors and their effects on partnerships not often considered in the literature.

Developing countries face diminishing development aid and time-limited donor commitments that challenge the long-term sustainability of donor-funded programs to improve the health of local populations. Increasing country ownership of the programs is one solution. Transitioning managerial and financial responsibility for donor-funded programs to governments and local stakeholders represents a highly advanced form of country ownership, but there are few successful examples among large-scale programs. We present a transition framework and describe how it was used to transfer the Bill & Melinda Gates Foundation's HIV/AIDS prevention program, the Avahan program, to the Government of India. Essential features recommended for the transition of donor-funded programs to governments include early planning with the government, aligning donor program components with government structures and funding models prior to transition, building government capacity through active technical and management support, budgeting for adequate support during and after the transition, and dividing the transition into phases to allow time for adjustments and corrections. The transition of programs to governments is an important sustainability strategy for efforts to scale up HIV prevention programs to reach the populations most at risk.

HIV and sexual risk continue to be central threats to the health and well-being of adolescents in the United States and abroad. Great strides have been made in creating interventions that reduce contracting and transmitting the deadly virus among adolescents. Numerous interventions have been designed and evaluated, with many having positive results in reducing adolescents' HIV risk behavior. However, the complexity of adolescents as well as limited effects on many sexual risk outcomes indicate that much more work needs to be done. This article provides a review of the literature on interventions among adolescents, summarizing why adolescents provide a unique challenge for HIV prevention, the intervention approaches that have been taken, and the challenges and recommendations for the future as the field confronts the neurobiologic dimension of risk.

Purpose of the review Recent breakthroughs in HIV-prevention science led us to evaluate the current state of combination HIV-prevention for injection drug users (IDUs). We review the recent literature focusing on possible reasons why coverage of prevention interventions for HIV, HCV and tuberculosis among IDUs remains dismal. We make recommendations for future HIV research and policy. Recent findings IDUs disproportionately under-utilize VCT, primary care and ART, especially in countries that have the largest burden of HIV among IDUs. IDUs present later in the course of HIV infection and experience greater morbidity and mortality. Why are IDUs under-represented in HIV-prevention research, access to treatment for both HIV and addiction, and access to HIV combination prevention? Possible explanations include addictophobia, apathy, and inattention, which we describe in the context of recent literature and events. Summary This commentary discusses the current state of HIV-prevention interventions for IDUs including, VCT, NSP, OST, ART and PrEP, and discusses ways to work towards true combination HIV-prevention for IDU populations. Communities need to overcome tacit assumptions that IDUs can navigate through systems that are maintained as separate silos, and take a rights-based approach to HIV-prevention to ensure that IDUs have equitable access to life-saving prevention and treatments.

As the science demonstrating strong evidence for voluntary medical male circumcision (VMMC) for HIV prevention has evolved, the President’s Emergency Plan for AIDS Relief (PEPFAR) has collaborated with international agencies, donors, and partner country governments supporting VMMC programming. Mathematical models forecast that quickly reaching a large number of uncircumcised men with VMMC in strategically chosen populations may dramatically reduce community-level HIV incidence and save billions of dollars in HIV care and treatment costs. Because VMMC is a 1-time procedure that confers life-long partial protection against HIV, programs for adult men are vital short-term investments with long-term benefits. VMMC also provides a unique opportunity to reach boys and men with HIV testing and counseling services and referrals for other HIV services, including treatment. After formal recommendations by WHO in 2007, priority countries have pursued expansion of VMMC. More than 1 million males have received VMMC thus far, with the most notable successes coming from Kenya’s Nyanza Province. However, a myriad of necessary cultural, political, and ethical considerations have moderated the pace of overall success. Because many millions more uncircumcised men would benefit from VMMC services now, US President Barack Obama committed PEPFAR to provide 4.7 million males with VMMC by 2014. Innovative circumcision methods—such as medical devices that remove the foreskin without injected anesthesia and/or sutures—are being rigorously evaluated. Incorporation of safe innovations into surgical VMMC programs may provide the opportunity to reach more men more quickly with services and dramatically reduce HIV incidence for all. PMID:22797745

This article discusses the specific actions taken by Yugoslavia in preventing the spread of HIV and AIDS in their country. Two years after the first HIV infection was diagnosed and recognized in 1985, a national level program was established based on the Global AIDS Strategy as defined in 1986 and the Global AIDS Program in 1987. Three essential elements in the program were prevention and control of risky behavior; safe public health procedures, and social tolerance. Among the first major activities organized was the First Conference on AIDS, held in 1987; it was followed in the following year by another conference which registered almost 150 papers regarding epidemiology, transfusiology, health education and drug dependence. In 1988, the Institute of Public Health of Serbia, Belgrade, published and distributed numerous pamphlets, folders, posters and video cassettes including 5,000 copies of the multi-colored poster "Beware of AIDS." The program activities have resulted in the design of a variety of projects that focused on specific problems and segments of the population, namely: AIDS Information for Dentists, The Health Education Program for Elementary School Children and AIDS, and Measures on AIDS Prevention in Health Facilities. Furthermore, The Resolution on Protecting the Population from STDs was passed in 1994 and a new Program of Protecting the Population from STDs was been adopted; this program includes activities on the prevention and control of HIV/AIDS, gonorrhea, syphilis and Hepatitis B.

Since many evaluations of HIV (human immunodeficiency virus) prevention programmes do not include data on costs, a preliminary analysis of the costs and outputs of a sample of HIV prevention projects was attempted. Case studies, representing six broad HIV prevention strategies in developing countries with differing levels of per capita gross domestic product, were sought on the basis of availability of data and potential generalizability. The six prevention strategies studied were mass media campaigns, peer education programmes, sexually transmitted disease treatment, condom social marketing, safe blood provision, and needle exchange/bleach provision programmes. Financial cost data were abstracted from published studies or were obtained directly from project coordinators. Although estimates of cost-effectiveness were not made, calculations of the relative cost per common process measure of output were compared. Condom distribution costs ranged from US$ 0.02 to 0.70 per condom distributed, and costs of strategies involving personal educational input ranged from US$ 0.15 to 12.59 per contact.

The study aims to examine the relationship between masculinity, vulnerability and the prevention of HIV/AIDS, based on reports from young men from the so-called urban working classes, taking into account not only the meanings attributed to prevention by these subjects, but also considering the dialectical relationship between the individual and society. The conceptual framework encompasses the three main aspects of hegemonic masculinity, prevention and vulnerability. This involves qualitative research based on the perspective of dialectical hermeneutics that uses the method of interpretation of meanings. The analysis yielded two main results, namely hegemonic masculinity as a vulnerability factor, and myths and prejudices as factors of vulnerability to HIV/AIDS. By way of conclusion, it reinforces the need for discussion of prevention encompassing the need to put on the agenda the construction of the sex/gender system around which to articulate the social meanings of masculinity and femininity that influence the structural plan of affective sexual relations in general and HIV/AIDS in particular.

Introduction The fastest growing group of adults living with human immunodeficiency virus (HIV), is women. As more women contract the virus, the number of children infected in utero, intra-partum, and during breastfeeding has been growing. This study assessed the knowledge and attitude of women of child bearing age towards the prevention of mother-to-child-transmission (PMTCT) of HIV. Materials and methods This is a descriptive cross sectional survey of 420 women of the reproductive age group (15–49 years) selected using a multistage sampling technique. Data were obtained using interviewer-administered, pretested, semistructured questionnaires. The data were analyzed using the Statistical Package for Social Sciences (SPSS) software version 15. Results A high level of awareness about HIV/acquired immunodeficiency syndrome (AIDS) was observed among the respondents (99.8%). The knowledge about MTCT and PMTCT of HIV was high, 92.1% and 91.4%, respectively. However, a significant portion (71.27%) of the study population had poor attitudes towards PMTCT of HIV. Conclusion Despite the high level of awareness of HIV/AIDS, and good knowledge about MTCT and PMTCT of HIV/AIDS among the respondents, the attitude towards PMTCT is poor. There is need for the involvement of the stakeholders in bridging the gap between knowledge and attitude of prevention of MTCT of HIV among women. PMID:23874124

This article seeks to advance ethical dialogue on choosing standards of prevention in clinical trials testing improved biomedical prevention methods for HIV. The stakes in this area of research are high, given the continued high rates of infection in many countries and the budget limitations that have constrained efforts to expand treatment for all who are currently HIV-infected. New prevention methods are still needed; at the same time, some existing prevention and treatment interventions have been proven effective but are not yet widely available in the countries where they most urgently needed. The ethical tensions in this field of clinical research are well known and have been the subject of extensive debate. There is no single clinical trial design that can optimize all the ethically important goals and commitments involved in research. Several recent articles have described the current ethical difficulties in designing HIV prevention trials, especially in resource limited settings; however, there is no consensus on how to handle clinical trial design decisions, and existing international ethical guidelines offer conflicting advice. This article acknowledges these deep ethical dilemmas and moves beyond a simple descriptive approach to advance an organized method for considering what clinical trial designs will be ethically acceptable for HIV prevention trials, balancing the relevant criteria and providing justification for specific design decisions.

Optimal adherence to antiretroviral therapy (ART) is central to achieving viral suppression and positive health outcomes in HIV-infected individuals. Virally suppressed individuals can also reduce the risk of HIV transmission to uninfected partners. Hence, adherence to ART has become both an HIV treatment and an HIV prevention strategy. However, achieving optimal ART adherence can be challenging, especially over the long term. It is increasingly important for clinicians and researchers to be abreast of the most recent developments in the field as new biomedical approaches to treatment emerge, and as guidelines for the use of pre-exposure prophylaxis (PrEP) are disseminated to providers serving HIV affected populations. Several reviews have described numerous ART adherence interventions that have been developed and/or tested with the most recent review including literature up to 2012. To augment the literature, we present a review of ART adherence interventions from 2013 – present. We included peer-reviewed journals as well as abstracts from two key conferences. PMID:25304006
Black heterosexual men (BHM) are seldom mentioned in HIV prevention research, policy, and interventions, despite evidence that heterosexual contact is becoming the leading exposure category for BHM. The disparate effect of HIV/AIDS on BHM; the debunked “down low” myth; the contexts of BHM's lives in terms of disproportionate poverty, unemployment, and incarceration; and a growing empirical base linking these factors to increased HIV risk, underscore the need to prioritize HIV risk and prevention initiatives for BHM. We highlighted the structural contexts of HIV risk for BHM, and four community-based approaches to address HIV risk and prevention for BHM: (1) men's health programs; (2) workforce and postincarceration release programs; (3) linkages to women's prevention programs; and (4) faith-based initiatives.

Abstract In the past few years, the transdisciplinary field of HIV prevention has reached several milestones. Topically applied tenofovir gel provided significant protection from sexual transmission of HIV in a large-scale clinical trial and oral Truvada (emtricitabine/tenofovir disoproxil fumarate) was recently approved for preexposure prophylaxis (PrEP) following two successful clinical trials in men and women. These achievements are tempered by the disappointing results of other clinical trials, which highlight the complexities of prevention research. In this perspective, we discuss scientific and developmental gaps for topical chemoprophylaxis of the sexual transmission of HIV, which depends on the complex interactions between the pharmacokinetics and pharmacodynamics of drugs, formulation and delivery systems, anatomic site of transmission, and host mucosal immune defenses. Despite the considerable time and resources devoted to unraveling the initial steps in sexual transmission of HIV, current knowledge is based on animal models and human explanted tissue, which may not fully recapitulate what happens clinically. Understanding these events, including the role that sex hormones, semen, and mucosal secretions play in transmission, and the interplay between innate immunity, the mucosal environment, and drug efficacy is paramount. This drives some of the most pressing questions in the field. PMID:22966871

Since the start of the HIV epidemic, community responses have been at the forefront of the response. Following the extraordinary expansion of global resources, the funding of community responses rose to reach at least US$690 million per year in the period 2005-2009. Since then, many civil society organisations (CSOs) have reported a drop in funding. Yet, the need for strong community responses is even more urgent, as shown by their role in reaching the Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast-Track targets. In the case of antiretroviral treatment, interventions need to be adopted by most people at risk of HIV in order to have a substantial effect on the prevention of HIV at the population level. This paper reviews the published literature on community responses, funding and effectiveness. Additional funding is certainly needed to increase the coverage of community-based interventions (CBIs), but current evidence on their effectiveness is extremely mixed, which does not provide clear guidance to policy makers. This is especially an issue for adolescent girls and young women in Eastern and Southern Africa, who face extremely high infection risk, but the biomedical prevention tools that have been proven effective for the general population still remain pilot projects for this group. Research is especially needed to isolate the factors affecting the likelihood that interventions targeting this group are consistently successful. Such work could be focused on the community organisations that are currently involved in delivering gender-sensitive interventions.

Despite disproportionately high HIV prevalence rates and high risk for HIV acquisition and transmission, trans women in the United States are less likely than other high-risk populations to be aware of their HIV status or to perceive HIV infection as a serious health threat. Furthermore, concurrently high rates of unstable housing, few legal employment opportunities, lack of social support, and distrust of social service providers limit trans women's interest or ability to be recruited by, retained within, or linked into HIV prevention and care services. This article provides an overview of the barriers that prevent many high-risk trans women from being recruited, linked, and retained within HIV prevention and care services as well as accessing HIV testing services, and discusses several strategies for overcoming these barriers. Best practices in working with high-risk trans women include hiring trans women indigenous to the local trans communities, designing culturally specific recruitment and retention strategies including the creation of living “community maps” to ensure successful community outreach, the construction of a trans women-specific CAB to create dialogue with community stakeholders including consumers, and extensive cultural sensitivity training for staff and community collaborators to sensitize them to the specific needs of high-risk trans women participants.

Background Combination HIV prevention interventions that integrate efficacious behavioral and biomedical strategies offer the potential to reduce new HIV infections. Purpose We overview the efficacy data for three biomedical HIV prevention approaches: microbicides, pre-exposure prophylaxis (PrEP), and an HIV vaccination, review factors associated with differential acceptability and uptake of these methods, and suggest strategies to optimize the effectiveness and dissemination of combination HIV prevention approaches. Methods A narrative review was conducted highlighting key efficacy data for microbicides, PrEP, and an HIV vaccination and summarizing acceptability data for each of the three biomedical HIV prevention approaches. Recommendations for the integration and dissemination of combined behavioral and biomedical HIV prevention approaches are provided. Results To date, microbicides and an HIV vaccination have demonstrated limited efficacy for the prevention of HIV. However, PrEP has demonstrated efficacy in reducing HIV incident infections. A diverse array of factors influences both hypothetical willingness and actual usage of each biomedical prevention method. Conclusions Strategies to effectively integrate and evaluate combination HIV prevention interventions are urgently needed. PMID:25216985

Despite increasing rates of HIV infection among young men who have sex with men (YMSM), only a minority participate in formal HIV prevention efforts. Semi-structured mixed-methods interviews were conducted with a diverse sample of YMSM (N = 100, M(age) = 25.0 years) in Los Angeles, California, to identify facilitators and barriers to participation in HIV prevention programs. Summative content analyses were used to evaluate transcribed field notes from these interviews. Results showed that 28.0 % of all participants had previously attended an HIV prevention program, and that 21.3 % of those who were also asked if they had ever participated in any research pertaining to HIV prevention had done so. A significantly higher percentage of those who had participated in HIV prevention programs had been tested for HIV in the past 6 months compared to those who had not (p < .05). The most frequently mentioned barriers to participation in such a program were being too busy to attend (12.0 %), not perceiving themselves to be at risk for HIV infection (14.0 %), and believing that they already knew everything they needed to know about HIV transmission (23.0 %). YMSM suggested that future interventions should use technology (e.g., the Internet, mobile devices), engage their social networks, and highlight HIV prevention as a means for community connection. Collectively, these results provide some explanations for why YMSM account for a minority of HIV prevention program participants and offer possible directions for future HIV prevention efforts that target YMSM.

The National Institutes of Health (NIH/NIMH), the Centers for Disease Control and Prevention (CDC), and the HIV/AIDS Bureau of the Health Resources and Services Administration (HRSA) support the CDC's Serostatus Approach to Fighting the HIV Epidemic (SAFE; Janssen et al., 2001). One aim of the strategy is to help individuals living with HIV (and their partners) adopt and sustain HIV and STD risk reduction, treatment adherence, and effective strategies for coping with HIV/AIDS. Efficacious interventions are needed by community organizations and clinics that provide evidence-based services. To expedite translation from research to practice, we convened scientist-practitioners, HIV treatment and prevention providers, and community/consumer members. In this article, we include an overview of prevention trials with HIV-positive persons presented at the meeting, discuss strengths and limitations, recommendations for future research, and discuss sponsoring agencies' plans for advancing prevention tailored for persons living with HIV.

The purpose of this study is to improve understanding of HIV vulnerability and opportunities for HIV prevention within the social networks of male-to-female transgender persons in San Salvador, El Salvador. We compare HIV prevalence and behavioral data from a sample of gay-identified men who have sex with men (MSM) (n = 279), heterosexual or bisexual identified MSM (n = 229) and transgender persons (n = 67) recruited using Respondent Driven Sampling. Transgender persons consistently reported higher rates of HIV risk behavior than the rest of the study population and were significantly more likely to be involved in sex work. While transgender persons reported the highest rates of exposure to HIV educational activities they had the lowest levels of HIV-related knowledge. Transgender respondents' social networks were homophilous and efficient at recruiting other transgender persons. Findings suggest that transgender social networks could provide an effective and culturally relevant opportunity for HIV prevention efforts in this vulnerable population.

Female-initiated methods of HIV prevention are needed to address barriers to HIV prevention rooted in gender inequalities. Understanding the sociocultural context of pre-exposure prophylaxis (PrEP) trials, including gender-based violence, is thus critical. MTN-003C (VOICE-C), a qualitative sub-study of the larger MTN-003 (VOICE) trial, examined sociocultural barriers and facilitators to PrEP amongst women in Johannesburg. We conducted focus-group discussions, in-depth interviews and ethnographic interviews with 102 trial participants, 22 male partners, 17 community advisory board members and 23 community stakeholders. We analysed how discussions of rape are emblematic of the gendered context in which HIV risk occurs. Rape emerged spontaneously in half of discussions with community advisory board members, two-thirds with stakeholders and among one-fifth of interviews/discussions with trial participants. Rape was used to reframe HIV risk as external to women's or partner's behaviour and to justify the importance of PrEP. Our research illustrates how women, in contexts of high levels of sexual violence, may use existing gender inequalities to negotiate PrEP use. This suggests that future interventions should simultaneously address harmful gender attitudes, as well as equip women with alternative means to negotiate product use, in order to more effectively empower women to protect themselves from HIV.

OBJECTIVES: AIDS service organizations (ASOs) rarely have access to the information needed to implement research-based HIV prevention interventions for their clients. We compared the effectiveness of 3 dissemination strategies for transferring HIV prevention models from the research arena to community providers of HIV prevention services. METHODS: Interviews were conducted with the directors of 74 ASOs to assess current HIV prevention services. ASOs were randomized to programs that provided (1) technical assistance manuals describing how to implement research-based HIV prevention interventions, (2) manuals plus a staff training workshop on how to conduct the implementation, or (3) manuals, the training workshop, and follow-up telephone consultation calls. Follow-up interviews determined whether the intervention model had been adopted. RESULTS: The dissemination package that provided ASOs with implementation manuals, staff training workshops, and follow-up consultation resulted in more frequent adoption and use of the research-based HIV prevention intervention for gay men, women, and other client populations. CONCLUSIONS: Strategies are needed to quickly transfer research-based HIV prevention methods to community providers of HIV prevention services. Active collaboration between researchers and service agencies results in more successful program adoption than distribution of implementation packages alone. PMID:10897186

Self-efficacy is a critical element for HIV prevention, however little is known about the predictors of self-efficacy for HIV prevention among Hispanic women. In this cross-sectional study we assessed if age, living with a partner, employment status, HIV knowledge, self-esteem, and intimate partner violence (IPV) predicted self-efficacy for HIV prevention in 548 Hispanic women in South Florida who participated in a randomized controlled trial (SEPA). The majority of Hispanic women reported high levels of self-efficacy for HIV prevention. Women who were older, living with a partner, with less HIV knowledge, and a history of IPV reported significantly lower levels of self-efficacy for HIV prevention. HIV knowledge was the most important predictor of self-efficacy for HIV prevention. Employment was not a significant predictor of self-efficacy for HIV prevention. Predictors identified in the study can be used to identify high-risk Hispanic women who are in need of HIV prevention interventions. PMID:22795758

Recently, behavioral prevention interventions for HIV have been criticized as being ineffective, costly, or inefficient. In this commentary, using HIV-positive men who have sex with men (MSM) as an illustrative high-risk population, we argue that the opposite is true – that behavioral interventions for HIV prevention, if implemented with the populations who need them, are affordable and critical for future prevention efforts. We base this argument on recent evidence showing that 1) adherence to antiretroviral treatment (ART) for prevention purposes is necessary to suppress HIV replication and reduce transmissibility, 2) individuals living with HIV have multiple psychosocial concerns that impact self-care and moderate the potential effectiveness of health behavior interventions, and 3) intensive interventions targeting both concerns together (psychosocial and HIV care) can show clinically significant improvement. We follow by comparing the cost of these types of interventions to the cost of standard clinical treatment for HIV with ART, and demonstrate a cost-savings of potential intensive behavioral interventions for, in this case, HIV-positive MSM who have uncontrolled virus. Keeping this evidence in mind, we conclude that individual intervention must remain a mainstay of HIV prevention for certain critical populations. PMID:26223385

Conversations about HIV prevention before engaging in sex may result in safer sex practices and decreased HIV transmission. However, partner communication for HIV prevention has been understudied among black/African American men who have sex with men (BMSM), a group that is disproportionately affected by HIV. We explored and described encounters and perceptions about HIV prevention conversations among BMSM and their sex partner(s) in New York City. We conducted an inductive thematic analysis of semi-structured interviews with BMSM who reported sex with a man in the previous 3 months. Interviews were professionally transcribed; Nvivo was used for data analysis. Twenty-two BMSM were included in this analysis; median age = 29.1 years; 71.4% self-identified as MSM; 85.7% were ever HIV tested; and 52.6% reported no disclosure or discussion about HIV status with their previous sex partner. The main themes were: (1) missed opportunities for HIV prevention conversations (e.g., no HIV prevention conversations or HIV prevention conversations after sex had occurred); (2) barriers to HIV prevention conversations (e.g., being in the moment; not wanting to pause); (3) emotional thoughts after sex (e.g., feeling worried about possible HIV exposure); and (4) rethinking relationships and sexual health (e.g., changed sex practices by asking partners' HIV status before sex; started using condoms). These findings offer insight into HIV prevention conversations by BMSM around the time of or during sexual encounters and may inform and strengthen partner-level HIV prevention communication interventions for BMSM.
This study, called the ANCHOR trial, will investigate whether screening and prevention methods similar to those used to prevent cervical cancer can help prevent anal cancer in HIV-infected men and women.

Introduction Critical technological advances have yielded a toolkit of HIV prevention strategies. This literature review sought to provide contextual and historical reflection needed to bridge the conceptual gap between clinical efficacy and community effectiveness (i.e. knowledge and usage) of existing HIV prevention options, especially in resource-poor settings. Methods Between January 2015 and October 2015, we reviewed scholarly and grey literatures to define treatment literacy and health literacy and assess the current need for literacy related to HIV prevention. The review included searches in electronic databases including MEDLINE, PsycINFO, PubMed, and Google Scholar. Permutations of the following search terms were used: “treatment literacy,” “treatment education,” “health literacy,” and “prevention literacy.” Through an iterative process of analyses and searches, titles and/or abstracts and reference lists of retrieved articles were reviewed for additional articles, and historical content analyses of grey literature and websites were additionally conducted. Results and discussion Treatment literacy was a well-established concept developed in the global South, which was later partially adopted by international agencies such as the World Health Organization. Treatment literacy emerged as more effective antiretroviral therapies became available. Developed from popular pedagogy and grassroots efforts during an intense struggle for treatment access, treatment literacy addressed the need to extend access to underserved communities and low-income settings that might otherwise be excluded from access. In contrast, prevention literacy is absent in the recent surge of new biomedical prevention strategies; prevention literacy was scarcely referenced and undertheorized in the available literature. Prevention efforts today include multimodal techniques, which jointly comprise a toolkit of biomedical, behavioural, and structural/environmental approaches
The public sector supports most HIV/AIDS prevention and care activities in developing countries, with significant funding provided by the US Agency for International Development, the Overseas Development Authority, the European Community, and international banking institutions such as the World Bank. Local nongovernmental organizations (NGOs) and international private voluntary organizations (PVOs) implement many of the grassroots prevention and care efforts in developing countries, but often require support from donor agencies. While the private commercial sector has played a minor role in supporting HIV/AIDS prevention and care efforts, a number of local and multinational companies are beginning to recognize the importance of protecting their workers from HIV infection. These companies are motivated by a sense of moral obligation and/or view HIV/AIDS prevention as a cost-effective investment. Mainly affecting the most economically productive age groups, the HIV/AIDS epidemic will have a significant impact upon private industry. Workplace-based prevention programs and policies, private sector resources for HIV/AIDS prevention and care, how HIV/AIDS programs can benefit from the private sector's experience in commercial service delivery, research and development, and corporate direct cash and in-kind contributions to government and NGO HIV/AIDS prevention activities are discussed. The AIDS Control and Prevention (AIDSCAP) Project's Businesses Managing AIDS Project helps owners and managers understand the potential impact of HIV/AIDS upon their businesses and the benefits of HIV/AIDS prevention.

The purpose of this study was to develop a theory-based program for Chinese early adolescents in order to promote their sexual and reproductive health and to prevent HIV infection. The program was designed based on the Information-Motivation-Behavioral skills model and a needs assessment among the stakeholders. A technical collaborative action research approach was applied. The study's participants were 102 early adolescents in a public middle school in mainland China, with the involvement of other key stakeholders, including 15 teachers and 12 parents. The results revealed a statistically significant improvement in the scores of sexual and reproductive health promotion and HIV prevention information, motivation, and behavioral skills after the program's implementation. Meanwhile, qualitative data from the early adolescents' reflection indicated that the content was useful and comprehensive, the trainers were friendly and knowledgeable, and participatory learning with an "edutainment" style was especially impressive. Additionally, the early adolescents expressed that they could apply the knowledge and skills in their daily life, which would benefit themselves and their family and peers. The Information-Motivation-Behavioral skills model could be explored in a non-Western context and the program was shown to be acceptable for use in a Chinese middle school setting.

Abstract HIV transmission is a major health concern. Global efforts are necessary to control the spread of infection. International collaborative studies in countries with high rates of new infections are essential for increasing knowledge on the behavioral, social, and biomedical aspects of HIV/AIDS and HIV transmission. Statistics indicate a growing HIV epidemic in Russia. There are alarming proportions of new cases attributed to heterosexual contact, and HIV is increasingly affecting people in the general population who are not part of any traditional high-risk group. Despite recent advances in HIV prevention, data on effective behavioral prevention approaches are limited. There is minimal evidence to suggest which types of prevention will be effective in reducing the risk for HIV transmission among people at risk in the general population. This article presents a review and discussion of an international research seminar, HIV Prevention Research: Evidence-Based Behavioral Approaches. Local and international interdisciplinary researchers gathered for the purposes of exchanging research results and information about ongoing studies, identifying gaps in knowledge, and discussing promising prevention strategies. The overarching goal was to advance HIV prevention research through scientific integration. The seminar provided an excellent platform for building research capacity in interdisciplinary HIV research in Russia and integrating research efforts with the international research community to contribute to HIV prevention research throughout the world.

This study measured audience reactions and receptivity to five draft HIV prevention messages developed for people living with HIV (PLWH) to inform future HIV message choice and audience targeting decisions. Our premise was that message concepts that receive wide audience appeal constitute a strong starting point for designing future HIV prevention messages, program activities, and health communication and marketing campaigns for PLWH. The majority of participants indicated agreement with evaluative statements that expressed favorable attitudes toward all five of the message concepts we evaluated. Participants gave the lowest approval to the message promoting sero-sorting. Sociodemographic characteristics played less of a role in predicting differences in message perceptions than attitudes, beliefs and sexual behavior. The general appeal for these messages is encouraging given that messages were expressed in plain text without the support of other creative elements that are commonly used in message execution. These results confirm the utility of systematic efforts to generate and screen message concepts prior to large-scale testing.

Social networking technologies are influential among men who have sex with men (MSM) and may be an important strategy for HIV prevention. We conducted focus groups with HIV positive and negative participants. Almost all participants used social networking sites to meet new friends and sexual partners. The main obstacle to effective HIV prevention campaigns in social networking platforms was stigmatization based on homosexuality as well as HIV status. Persistent stigma associated with HIV status and disclosure was cited as a top reason for avoiding HIV-related conversations while meeting new partners using social technologies. Further, social networking sites have different social etiquettes and rules that may increase HIV risk by discouraging HIV status disclosure. Overall, successful interventions for MSM using social networking technologies must consider aspects of privacy, stigma, and social norms in order to enact HIV reduction among MSM.

This study is to identify the risk behaviors of the Japanese that may lead to HIV infection and the behaviors that prevent such infection, as well as their background factors. Two behavioral surveys were conducted for the present study. (1) For international comparison on knowledge, attitudes, beliefs, and practices (KABP) related to HIV/AIDS, we conducted a survey on a sample of 10,000 adults, randomly selected from a nationwide population in Japan; and (2) for sexual partner relation, we conducted a survey on a sample of 10,000 adults randomly selected from a population in five major cities of Japan. Our main findings include: (1) Most of the Japanese adult did not regard AIDS as a major threat in the area where they lived; (2) People in their twenties are too casual about "having sex without using a condom with someone they've met for the first time and know little about"; (3) Thirteen percent (19% male, 8% female) of those with a steady sex partner including a spouse, on average, had sex with 2.4 non-steady partners in the previous year; and (4) Only 25 percent used condoms always when they engaged in casual sex during the previous four weeks. These risk behaviors of the Japanese adults might lead to an explosive rise in the number of HIV-infected in the near future unless steps are taken immediately to prevent it.

In 1999, IOM issued a report that recommended that the Centers for Disease Control and Prevention should disseminate evidence-based HIV prevention interventions (EBIs) to be implemented by health departments, community-based organizations, drug treatment centers, and clinics. Based on these recommendations, the Diffusion of Effective Behavioral Interventions Project was initiated in 2000 and began disseminating interventions into public health practice. For 15 years, the Centers for Disease Control and Prevention has disseminated 29 EBIs to more than 11,300 agencies. Lessons were identified during the 15 years of implementation regarding successful methods of dissemination of EBIs. Lessons around selecting interventions for dissemination, developing a dissemination infrastructure including a resource website (https://effectiveinterventions.cdc.gov), and engagement with stakeholders are discussed. A continuous development approach ensured that intervention implementation materials, instructions, and technical assistance were all tailored to the needs of end users, focus populations, and agency capacities. Six follow-up studies demonstrated that adopters of EBIs were able to obtain comparable outcomes to those of the original efficacy research. The Diffusion of Effective Behavioral Interventions Project may offer guidance for other large, national, evidence-based public health dissemination projects.
Identifying and Prioritizing Implementation Barriers, Gaps, and Strategies Through the Nigeria Implementation Science Alliance: Getting to Zero in the Prevention of Mother-to-Child Transmission of HIV

Background: In 2013, Nigeria accounted for 15% of the 1.3 million pregnant women living with HIV in sub-Saharan Africa and 26% of new infections among children worldwide. Despite this, less than 20% of pregnant women in Nigeria received an HIV test during pregnancy, and only 23% of HIV-infected pregnant women received appropriate intervention following HIV diagnosis. This article reports findings from 2 structured group exercises conducted at the first Nigeria Implementation Science Alliance Conference to identify (1) barriers and research gaps related to prevention of mother-to-child transmission (PMTCT) and (2) potential strategies and interventions that could address PMTCT challenges. Methods: Two 1-hour structured group exercises were conducted with 10 groups of 14–15 individuals (n = 145), who were asked to brainstorm barriers and strategies and to rank their top 3 in each category. Data analysis eliminated duplicate responses and categorized each of the priorities along the HIV care continuum: HIV diagnosis, linkage to care, or retention in care. Results: Participating stakeholders identified 20 unique barriers and research gaps related to PMTCT across the HIV continuum. Twenty-five unique interventions and implementation strategies were identified. Similar to the barriers and research gaps, these interventions and strategies were distributed across the HIV care continuum. Conclusions: The barriers and strategies identified in this study represent important pathways to progress addressing MTCT. The deliberate involvement of state and federal policy makers, program implementers, and researchers helps ensure that they are relevant and actionable. PMID:27355504

In the past 25 years, the field of HIV prevention research has been transformed repeatedly. Today, effective HIV prevention requires a combination of behavioral, biomedical, and structural intervention strategies. Risk of transmitting or acquiring HIV is reduced by consistent male and female-condom use, reductions in concurrent and/or sequential sexual and needle-sharing partners, male circumcision, and treatment with antiretroviral medications. At least 144 behavioral prevention programs have been found effective in reducing HIV transmission acts; however, scale up of these programs has not occurred outside of the United States. A series of recent failures of HIV-prevention efficacy trials for biomedical innovations such as HIV vaccines, treating herpes simplex 2 and other sexually transmitted infections, and diaphragm and microbicide barriers highlights the need for behavioral strategies to accompany biomedical strategies. This challenges prevention researchers to reconceptualize how cost-effective, useful, realistic, and sustainable prevention programs will be designed, delivered, tested, and diffused. The next generation of HIV prevention science must draw from the successes of existing evidence-based interventions and the expertise of the market sector to integrate preventive innovations and behaviors into everyday routines.

Social marketing involves applying marketing principles to promote social goods. In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide.
Clinical and epidemiologic research has identified increasingly effective interventions to reduce mother to child HIV transmission in resource-limited settings These scientific breakthroughs have been implemented in some programmes, although much remains to be done to improve coverage and quality of these programmes. But prevention of HIV transmission is not enough. It is necessary also to consider ways to improve maternal health and protect child survival. A win-win approach is to ensure that all pregnant and lactating women with CD4 counts of <350 cells/mm3 have access to antiretroviral therapy. On its own, this approach will substantially improve maternal health and markedly reduce mother to child HIV transmission during pregnancy and delivery and through breastfeeding. This approach can be combined with additional interventions for women with higher CD4 counts, either extended prophylaxis to infants or extended regimens of antiretroviral drugs to women, to reduce transmission even further. Attempts to encourage women to abstain from all breastfeeding or to shorten the optimal duration of breastfeeding have led to increases in mortality among both uninfected and infected children. A better approach is to support breastfeeding while strengthening programmes to provide antiretroviral therapy for pregnant and lactating women who need it and offering antiretroviral drug interventions through the duration of breastfeeding. This will lead to reduced HIV transmission and will protect the health of women without compromising the health and well-being of infants and young children. PMID:20015345
Data suggest that HIV prevalence rates among Muslim populations may be increasing due to unprotected sexual intercourse and shared injection equipment, despite popular belief that adherence to religious injunctions has shielded Muslim populations from the HIV epidemic. HIV prevention programs targeting Muslim populations to date have often lacked a theoretical foundation and have neglected the important Islamic concept of jihad, or struggle. This article reviews the cultural and religious factors that may facilitate or reduce HIV risk in Muslim communities. The theory of reasoned action and a harm reduction approach are utilized to demonstrate how the important concept of jihad can be integrated with HIV prevention theory to develop HIV prevention approaches at individual and structural levels. The proposed approach to HIV prevention must be validated, refined, and evaluated for specific cultures and locales through field testing.

Adolescents are the only age group with growing AIDS-related morbidity and mortality in Eastern and Southern Africa, making HIV prevention research among this population an urgent priority. Structural deprivations are key drivers of adolescent HIV infection in this region. Biomedical interventions must be combined with behavioural and social interventions to alleviate the socio-structural determinants of HIV infection. There is growing evidence that social protection has the potential to reduce the risk of HIV infection among children and adolescents. This research combined expert consultations with a rigorous review of academic and policy literature on the effectiveness of social protection for HIV prevention among children and adolescents, including prevention for those already HIV-positive. The study had three goals: (i) assess the evidence on the effectiveness of social protection for HIV prevention, (ii) consider key challenges to implementing social protection programmes that promote HIV prevention, and (iii) identify critical research gaps in social protection and HIV prevention, in Eastern and Southern Africa. Causal pathways of inequality, poverty, gender and HIV risk require flexible and responsive social protection mechanisms. Results confirmed that HIV-inclusive child-and adolescent-sensitive social protection has the potential to interrupt risk pathways to HIV infection and foster resilience. In particular, empirical evidence (literature and expert feedback) detailed the effectiveness of combination social protection particularly cash/in-kind components combined with "care" and "capability" among children and adolescents. Social protection programmes should be dynamic and flexible, and consider age, gender, HIV-related stigma, and context, including cultural norms, which offer opportunities to improve programmatic coverage, reach and uptake. Effective HIV prevention also requires integrated social protection policies, developed through strong national

HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported in African fishing villages, local distribution patterns of HIV infection in the communities surrounding these villages have not been thoroughly analyzed. The objective of this study was to investigate the geographical distribution patterns of HIV infection in communities surrounding African fishing villages. In 2011, we applied age- and sex-stratified random sampling to collect 1,957 blood samples from 42,617 individuals registered in the Health and Demographic Surveillance System in Mbita, which is located on the shore of Lake Victoria in western Kenya. We used these samples to evaluate existing antibody detection assays for several infectious diseases, including HIV antibody titers. Based on the results of the assays, we evaluated the prevalence of HIV infection according to sex, age, and altitude of participating households. We also used Kulldorff’s spatial scan statistic to test for HIV clustering in the study area. The prevalence of HIV at our study site was 25.3%. Compared with the younger age group (15–19 years), adults aged 30–34 years were 6.71 times more likely to be HIV-positive, and the estimated HIV-positive population among women was 1.43 times larger than among men. Kulldorff’s spatial scan statistic detected one marginally significant (P = 0.055) HIV-positive and one significant HIV-negative cluster (P = 0.047) in the study area. These results suggest a homogeneous HIV distribution in the communities surrounding fishing villages. In addition to individual behavior, more complex and diverse factors related to the social and cultural environment can contribute to a homogeneous distribution pattern of HIV infection outside of African fishing villages. To reduce rates of transmission in HIV-endemic areas, HIV prevention and control programs optimized for the local environment need to be developed. PMID:26862764

HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported in African fishing villages, local distribution patterns of HIV infection in the communities surrounding these villages have not been thoroughly analyzed. The objective of this study was to investigate the geographical distribution patterns of HIV infection in communities surrounding African fishing villages. In 2011, we applied age- and sex-stratified random sampling to collect 1,957 blood samples from 42,617 individuals registered in the Health and Demographic Surveillance System in Mbita, which is located on the shore of Lake Victoria in western Kenya. We used these samples to evaluate existing antibody detection assays for several infectious diseases, including HIV antibody titers. Based on the results of the assays, we evaluated the prevalence of HIV infection according to sex, age, and altitude of participating households. We also used Kulldorff's spatial scan statistic to test for HIV clustering in the study area. The prevalence of HIV at our study site was 25.3%. Compared with the younger age group (15-19 years), adults aged 30-34 years were 6.71 times more likely to be HIV-positive, and the estimated HIV-positive population among women was 1.43 times larger than among men. Kulldorff's spatial scan statistic detected one marginally significant (P = 0.055) HIV-positive and one significant HIV-negative cluster (P = 0.047) in the study area. These results suggest a homogeneous HIV distribution in the communities surrounding fishing villages. In addition to individual behavior, more complex and diverse factors related to the social and cultural environment can contribute to a homogeneous distribution pattern of HIV infection outside of African fishing villages. To reduce rates of transmission in HIV-endemic areas, HIV prevention and control programs optimized for the local environment need to be developed.

Introduction As young people living with HIV grow their sexual behaviour and it's implication on HIV prevention is of concern. This study describes the sexual risk related-behaviours and factors associated with abstinence among Youth Living with HIV in central Uganda. Methods We conducted a cross-sectional study among 338 unmarried youth between 15 and 24 years accessing HIV care in central Uganda. Data was collected using interviewer administered structured questionnaires. Adjusted prevalence proportion ratios (adj. PPRs) of factors associated with sexual abstinence for at least six months were determined by multivariable log-binomial regression. Results Overall, 79% (269/338) of respondents were abstaining from sexual intercourse for atleast six months, although, 45% (150/338) had ever been sexually active. Of the 283 respondents who desired to get married in future, 40% preferred negative marriage partners. Only 31% (39/126) of respondents in boy/girl relationships had disclosed their HIV status to their partners. Among those currently sexually active (n = 69), 57% did not consistently use condoms and 30% had more than one sexual partner in the past six months. The adj.PRR of abstinence was higher among youth between 15 and 19 years compared to those between 20 and 24 years (adj. PPR = 1.26, 95% CI; 1.08-1.46). The prevalence of abstinence was significantly lower among respondent who consumed alcohol (adj. PPR = 0.31, 95% CI 0.16-0.61). Conclusion Tailored interventions promoting disclosure, consistent condoms use and discouraging alcohol consumption among sero-positive youth could reduce HIV transmission risk. PMID:27642390

Objective Guidelines recommend risk-reduction counseling by HIV providers to all HIV-infected persons. Among HIV-infected adults receiving medical care in the United States, we estimated prevalence of exposure to three types of HIV/sexually transmitted disease (STD) risk-reduction interventions and described the characteristics of persons who received these interventions. Design Data were from the Medical Monitoring Project (MMP), a supplemental HIV surveillance system designed to produce nationally representative estimates of behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States. Methods Descriptive analyses were conducted to estimate the exposure to each type of HIV/STD risk-reduction intervention. Bivariate and multivariable analyses were conducted to assess associations between the selected correlates with each exposure variable. Results About 44% of participants reported a one-on-one conversation with a health care provider about HIV/STD prevention, 30% with a prevention program worker, 16% reported participation in a small group risk-reduction intervention, and 52% reported receiving at least one of the three interventions in the past 12 months. Minority race/ethnicity, low income, and risky sexual behavior consistently predicted greater intervention exposure. However, 39% of persons who reported risky sex did not receive any HIV/STD risk-reduction interventions. Conclusions HIV-infected persons in care with fewer resources or those who engaged in risk behaviors were more likely to receive HIV/STD risk-reduction interventions. However, less than half of HIV-infected persons in care received HIV/STD prevention counseling from their provider, an intervention that has been shown to be effective and is supported by guidelines.

Universal HIV testing and immediate antiretroviral therapy for infected individuals has been proposed as a way of reducing the transmission of HIV and thereby bringing the HIV epidemic under control. It is unclear whether transmission during early HIV infection--before individuals are likely to have been diagnosed with HIV and started on antiretroviral therapy--will compromise the effectiveness of treatment as prevention. This article presents two opposing viewpoints by Powers, Miller, and Cohen, and Williams and Dye, followed by a commentary by Fraser.
In May 1997, the Advisory Committee for HIV and STD Prevention (ACHSP) reviewed data on the relation between curable sexually transmitted diseases (STDs) and the risk for sexual transmission of human immunodeficiency virus (HIV). ACHSP considered that the evidence was strong that early detection and treatment of other STDs is an effective strategy for preventing sexually transmitted HIV infection but was concerned that this strategy has not been clearly articulated or implemented as a core strategy for HIV prevention in the United States. In the context of persistently high prevalence of STDs in many parts of the United States and with emerging evidence that the U.S. epidemic of HIV infection and acquired immunodeficiency syndrome (AIDS) increasingly is affecting population groups with the highest rates of curable STDs, ACHSP recommends the following actions: Early detection and treatment of curable STDs should become a major, explicit component of comprehensive HIV prevention programs at national, state, and local levels. In areas where STDS that facilitate HIV transmission are prevalent, screening and treatment programs should be expanded. HIV and STD prevention programs in the United States, together with private and public sector partners, should take joint responsibility for implementing this strategy.

Nigeria is second in the world for the number of people with HIV and has a high rate of mother-to-child transmission (MTCT). Over 60% of births in Nigeria occur outside of health care facilities, and because of this, Traditional Birth Attendants (TBAs) play a significant role in maternal and child health. It is important that TBAs be knowledgeable about HIV prevention. The purpose of this study was to determine the impact of HIV testing and counseling (HTC) knowledge on the HIV prevention practices among TBAs in Nigeria. Five hundred TBAs were surveyed. Chi-square and logistic regression were used to assess differences in HIV prevention practices between TBAs with and without HTC knowledge. TBAs with HTC knowledge are significantly more likely to engage in HIV prevention practices than TBAs without HTC. Prevention practices included: wearing gloves during delivery (p < 0.01), sterilization of delivery equipment (p < 0.01), participation in blood safety training (p < 0.01), and disposal of sharps (p < 0.01). As long as a high percent of births occur outside health care facilities in Nigeria, there will be a need for TBAs. Providing TBAs with HTC training increases HIV prevention practices and can be a key to improve maternal and child health.

Asian Pacific Islander communities in the United States have experienced an alarming increase in HIV infection over the past few years, possibly due to a lack of knowledge and the relative absence of appropriate educational interventions. The authors propose a new approach to the development of HIV prevention programs in U.S. southeast Asian communities. This article reviews the cultural and economic factors that may facilitate HIV transmission within these communities. Relying on the basic precepts of Buddhism, the dominant religion of many southeast Asian populations in the United States, the health belief model is utilized to demonstrate how recognizable, acceptable religious constructs can be integrated into the content of HIV prevention messages. This integration of religious concepts with HIV prevention messages may increase the likelihood that the message audience will accept the prevention messages as relevant. This nuanced approach to HIV prevention must be validated and refined through field research.

Abstinence-until-marriage (AUM) - strongly supported by religious conservatives in the USA - became a key element of initial human immunodeficiency virus (HIV) prevention efforts under the President's Emergency Plan for AIDS Relief (PEPFAR). AUM programmes have demonstrated limited efficacy in changing behaviours, promoted medically inaccurate information and withheld life-saving information about risk reduction. A focus on AUM also undermined national efforts in Africa to create integrated youth HIV prevention programmes. PEPFAR prevention efforts after 2008 shifted to science-based programming, however, vestiges of AUM remain. Primary prevention programmes within PEPFAR are essential and nations must be able to design HIV prevention based on local needs and prevention science.

Pneumatic nail guns are ubiquitous at residential construction sites across the United States. These tools are noted for the traumatic injuries that can occur from their operation. Different trigger mechanisms on these tools are associated with different levels of risk. Residential building subcontractors and workers, both native-born and immigrant, were brought together in focus groups to discuss their attitudes and beliefs regarding risk factors for nail gun injury as well as barriers to the adoption of safer technology. Participants' comments are organized first by influences on traumatic injury occurrence or prevention and later by sociotechnical system category. Participants attributed influences on injury risk to personal and external causation factors in all sociotechnical system categories; however, participants more frequently described influences on injury prevention as related to workers' behaviors, rather than to external factors. A discussion of these influences with respect to attribution theory and sociotechnical models of injury causation is presented.

Mobile populations are at increased risk for HIV infection. Exposure to HIV prevention messages at all phases of the migration process may help decrease im/migrants’ HIV risk. We investigated levels of exposure to HIV prevention messages, factors associated with message exposure, and the association between exposure to prevention messages and HIV testing behavior among Mexican im/migrants at different phases of the migration process. We conducted a cross-sectional, probability survey of Mexican im/migrants (N=3,149) traveling through the border city of Tijuana, Mexico. The results indicate limited exposure to prevention messages (57%–75%) and suboptimal last 12-month HIV testing rates (14%–25%) across five migration phases. Compared to pre-departure levels (75%), exposure to messages decreases at all post-departure migration phases (57%–63%, p<.001). In general, exposure to prevention messages is positively associated with greater odds of HIV testing at the pre-departure, destination, and interception phases. Binational efforts need to be intensified to reach and deliver HIV prevention to Mexican im/migrants across the migration continuum. PMID:26595267

Background The fact that HIV prevention often deals with politicised sexual and drug taking behaviour is well known, but structural HIV prevention interventions in particular can involve alteration of social arrangements over which there may be further contested values at stake. As such, normative frameworks are required to inform HIV prevention decisions and avoid conflicts between social goals. Methods This paper provides a conceptual review and discussion of the normative issues surrounding structural HIV prevention strategies. It applies political and ethical concepts to explore the contested nature of HIV planning and suggests conceptual frameworks to inform future structural HIV responses. Results HIV prevention is an activity that cannot be pursued without making value judgements; it is inherently political. Appeals to health outcomes alone are insufficient when intervention strategies have broader social impacts, or when incidence reduction can be achieved at the expense of other social values such as freedom, equality, or economic growth. This is illustrated by the widespread unacceptability of forced isolation which may be efficacious in preventing spread of infectious agents, but conflicts with other social values. Conclusions While no universal value system exists, the capability approach provides one potential framework to help overcome seeming contradictions or value trade-offs in structural HIV prevention approaches. However, even within the capability approach, valuations must still be made. Making normative values explicit in decision making processes is required to ensure transparency, accountability, and representativeness of the public interest, while ensuring structural HIV prevention efforts align with broader social development goals as well.

Since 1994, the Centers for Disease Control and Prevention has required that the 65 health department grantees that receive funding for HIV prevention interventions engage in a community planning process to involve affected communities in local prevention decision making; to increase the use of epidemiological data to target HIV prevention resources; and to ensure that the planning process takes into account scientific information on the effectiveness and efficiency of different HIV interventions. Local community planning groups are charged with identifying and prioritizing unmet HIV prevention needs in their communities, as well as prioritizing prevention interventions designed to address these needs. Their recommendations, in turn, form the basis for the local health department's request for HIV prevention funding from the Centers for Disease Control and Prevention. Given the community planning process's central role in the allocation of federal HIV prevention funds, it is critical that sound decision-making procedures inform this process. In this article, we review the basics of the community planning prioritization process and summarize the decision-making experiences of community planning groups across the US. We then describe several priority-setting tools and decision analytic models that have been developed to assist in HIV community planning prioritization and discuss their strengths and weaknesses. Finally, we offer suggestions for improving the decision-analytic basis for HIV prevention community planning.

In northern Uganda, physical and structural violence (political repression, economic inequality, and gender-based discrimination) increase vulnerability to HIV infection. In settings of war, traditional HIV prevention that solely promotes risk avoidance and risk reduction and assumes the existence of personal choice inadequately addresses the realities of HIV transmission. The design of HIV prevention strategies in northern Uganda must recognize how HIV transmission occurs and the factors that put people at risk for infection. A human rights approach provides a viable model for achieving this aim.

The prevalence of HIV/AIDS infection among prisoners is 3 to 4 times higher than in the U.S. population. Given that one in seven HIV-positive Americans pass through a correctional facility every year, the criminal justice system is in an ideal position to aggressively implement effective HIV education, treatment, and prevention. This study examines barriers to the effective delivery of these services and evaluates differences in risk perception among nearly 600 female and male inmates. The results underscore gender differences in Perceived Risk of Seroconversion and Exposure to HIV Education, suggesting that jails should implement gender-specific HIV prevention programming.

In these almost thirty years since the epidemic of HIV infection strategies have been developed to decrease the transmission risk when a non-infected person comes into contact with HIV. One of the key landmarks was the use zidovudine was shown to reduce the risk of HIV infection by vertical transmission from 25% to 8% when given from the second trimester of pregnancy, during partum and for several weeks in the newborn. These strategies have been subsequently perfected until achieving vertical transmission rates less than 1%. Almost at the same time, strategies have been developed in an attempt to reduce the risk of transmission of infection after occupational accidents and, in the last few years prophylaxis after non-occupational exposure has been a field of particular concern. Even in this past year several experiments on pre-exposure prophylaxis have been published, which are generating an intense debate on is applicability. In this article, we analyse the state of the art in the prevention of vertical transmission and occupational and non-occupational prophylaxis, from a perspective of applying this in the developed world. We also review the published data on pre-exposure prophylaxis.

There is no viable substitute for re-energizing, funding and supporting culturally attuned, locally staffed HIV advocacy and prevention programmes, especially in resource poor settings. The evidence that such interventions are effective remains compelling; and although the cost implications are not negligible, the medium to long-term outcomes must be regarded not as complementary, but as integral, to biomedical interventions. The success of the anti-retroviral drugs upscale has enabled a noticeable improvement in AIDS related morbidity and mortality in the recent years; yet the underlying dynamics of the epidemic remains undetermined by the rate at which new infections are taking place in relation to the number of AIDS deaths. While the rate of new HIV infections is stabilising in some of the hardest hit countries, it remains far too high and the future cost of maintaining an ever-expanding pool of people reliant on daily drugs for survival is unsustainable. Countries must exercise caution in continuing to focus on treatment as a ‘quick fix’ to end AIDS as a public health concern. HIV is a socially culturally induced crisis and, as such, a variety of measures are needed simultaneously to appeal to different people, groups and circumstances. PMID:27347272

The estimated number of HIV cases in Asia now exceeds the "worst case" scenario envisioned by the World Bank in 1993. While prevention efforts have failed to contain the epidemic in other parts of the world, Asia's private sector has the resources to contain the epidemic if it acts quickly. In parts of Asia, work place-based medical and health services already exist, but, to date, efforts to gain the cooperation of business and industry in HIV prevention programs have led to disappointment. Businesses in Thailand, on the other hand, have begun a vigorous prevention campaign led by the Thailand Business Coalition on AIDS. The countries where the epidemic has not yet made a big impact (Japan, Korea, Hong Kong, Indonesia, Viet Nam, and the Philippines) are those where intervention could be most effective. Unfortunately, little corporate cooperation is occurring in these areas. Asian companies seem to fear contamination from the disease if they engage in prevention activities. Businesses in Asia have not faced the reality of the costs of AIDS which will rob companies of highly skilled workers who are expensive to replace, drive away foreign capital, and shrink the home market as people dedicate their resources to health care. While the impact of AIDS on businesses follows a tiered approach, all enterprises will eventually be affected adversely. The interrelated nature of Asia economies will also mean that even nations which are not experiencing the epidemic will feel its economic impact (for example, Japan will see its gross national product decrease because of trade losses caused by the epidemic in Thailand). Prevention efforts by businesses must be supported and encouraged by governments with financial and other incentives. Multinational corporations can have an effect on national companies as well as organize programs for their own employees. Because they depend upon longterm strategic thinking, Asian financial institutions are beginning to understand the role that

Prisons and prison inmates present important targets for HIV/AIDS prevention interventions. Inmates often have histories of high-risk behavior that place them in danger of contracting HIV/AIDS, and rates of HIV/AIDS tend to be much higher in this population. The goal of this study was to assess the effectiveness of a prison-based HIV/AIDS intervention to change attitudes toward HIV prevention, norms supporting HIV prevention, perceived behavioral control (i.e., self-efficacy) for HIV prevention behaviors, and intentions to engage in HIV prevention behaviors postrelease. The intervention also had the goal of encouraging inmates to become HIV/AIDS peer educators. The intervention appeared most successful at influencing beliefs and behaviors related to peer education and somewhat successful at influencing beliefs and intentions related to condom use. Analyses also showed some significant differences in effectiveness by race/ethnicity. Results are discussed from the perspectives of both research and practice with regard to prison-based HIV prevention efforts.

Ethnic churches attended by first generation Chinese immigrants are uniquely positioned to address emerging HIV prevention and care needs within the Chinese community at-large. Efforts to develop faith-based HIV programs necessitate identifying how HIV intersects with the sinicization of Christianity within Chinese churches. This paper will review the process of contextualizing HIV within theological and cultural frameworks that are meaningful for ethnic Chinese church leaders and members. The authors specifically propose two points of integration between public health and ecclesial functions: (1) HIV stigma-mitigation initiatives as informed by Christo-centric teachings of compassion and justice, and (2) HIV prevention and care reframed as social responsibility and informed by the Christian tradition of evangelism. Systems and practices that hinder and promote the involvement of Chinese churches in HIV prevention, care, and stigma-reduction will be discussed. PMID:23483037

In spite of access to behavioral and biomedical HIV prevention strategies, HIV transmission occurs. For HIV-serodiscordant couples, prevention programs can be tailored to address individual and couples' needs to preserve their relationship while minimizing HIV risk. Programs for serodiscordant couples may benefit from learning from experiences of couples who transmit HIV. We conducted 20 individual in-depth interviews with 10 initially HIV-serodiscordant couples who transmitted HIV during prospective follow-up at a peri-urban research site in Thika, Kenya. Data were analyzed inductively to identify situations that led to prevention failure and coping mechanisms. Inconsistent condom use driven by low HIV risk perception and alcohol use often preceded seroconversion while persistent blame frequently hindered couples' communication soon after seroconversion. In this emerging era of antiretroviral-based HIV prevention, couples' counseling can capitalize on opportunities to foster a supportive environment to discuss initiation and adherence to time-limited pre-exposure prophylaxis and lifelong antiretroviral therapy, in addition to strategies to reduce alcohol use, diffuse blame, and use condoms.

The incidence of HIV remains alarmingly high in many parts of the world. Prophylactic use of antiretrovirals, capable of concentrating in the anatomical sites of transmission, may reduce the risk of infection after an unprotected sexual exposure. To date, orally and topically administered antiretrovirals have exhibited variable success in preventing HIV transmission in large-scale clinical trials. Antiretroviral mucosal pharmacokinetics may help explain the outcomes of these investigations. Penetration and accumulation of antiretrovirals into sites of transmission can influence dosing strategies and pre-exposure prophylaxis clinical trial design. Antiretroviral tissue distribution varies widely within and between drug classes, attributed in part to their physicochemical properties and tissue-specific drug transporter expression. Nucleoside (-tide) reverse transcriptase inhibitors, the CCR5 antagonist maraviroc, and the integrase inhibitor raltegravir demonstrate the highest penetration into the male and female reproductive tracts and colorectal tissue relative to blood. This review will describe antiretroviral exposure in anatomic sites of transmission, and place these findings in context with the prevention of HIV and the efficacy of pre-exposure prophylactic strategies.

HIV/AIDS fatalism may impact on individuals' health-seeking behaviour and HIV-prevention efforts. This descriptive study measured levels of HIV/AIDS fatalism and documented HIV/AIDS beliefs and practices among a sample of Gabonese and Malians living in Gabon, West Africa. The Powe Fatalism Inventory-HIV/AIDS version was used to measure levels of fatalism, while a short-answer survey was used to document personal beliefs and behaviours related to HIV and AIDS among 160 people in Gabon. The mean score of HIV/AIDS fatalism for the total sample was 6.8 on a 15-point scale. Malians had a more fatalistic outlook than Gabonese (mean scores 9.4 versus 5.3), Muslims were more fatalistic than persons of other religions (mean scores 9.2 versus 5.3), while healthcare providers were less fatalistic than non-providers (mean scores 3.8 versus 7.4). People that did not believe that HIV/AIDS is a punishment from God had a lower mean score of fatalism than those who did. Most of the sample believed that AIDS is a real disease, and most did not think that only immoral people discuss HIV and AIDS. The HIV-prevention indicators that related to lower scores of fatalism included knowing HIV-positive people, having had more years of formal education, a willingness to disclose one's HIV status (if known), and experience of HIV/AIDS education. Respondents who had tested for HIV were no less fatalistic than those who had never tested. The findings provide data from a part of the world where HIV/AIDS beliefs have rarely been documented. The results indicate a need for additional studies on correlations between HIV/ AIDS fatalism, HIV-prevention behaviours, and religious belief systems.

subgroup analyses among the observational studies to see if the effect of ART on prevention of HIV differed by the index partner’s CD4 cell count. Among couples in which the infected partner had ≥350 CD4 cells/µL, we estimated a rate ratio of 0.12 [95% CI 0.01, 1.99]. In this subgroup, there were 247 transmissions in untreated couples and 30 in treated couples. Authors’ conclusions ART is a potent intervention for prevention of HIV in discordant couples in which the index partner has ≤550 CD4 cells/µL. A recent multicentre RCT confirms the suspected benefit seen in earlier observational studies and reported in more recent ones. Questions remain about durability of protection, the balance of benefits and adverse events associated with earlier therapy, long-term adherence and transmission of ART-resistant strains to partners. Resource limitations and implementation challenges must also be addressed. Counselling, support, and follow up, as well as mutual disclosure, may have a role in supporting adherence, so programmes should be designed with these components. In addition to ART provision, the operational aspects of delivering such programmes must be considered. PMID:23633367

With the prevalence of HIV among pregnant women higher than 35% in some parts of sub-Saharan Africa, the number of HIV-infected children will continue to grow. It is estimated that almost 70% of the approximately 500,000 children who became infected with HIV in 1995 were born in sub-Saharan Africa. An effective intervention to prevent the vertical transmission of HIV is therefore most urgently needed in Africa. Following the release of the results of the AIDS Clinical Trials Group (ACTG) 076 study, the routine use of zidovudine (AZT) among HIV-infected pregnant women in the US and Europe has resulted in a significant reduction in the rate of mother-to-child vertical HIV transmission. However, most women in Africa will not benefit from these advances in the immediate future due to inadequate prenatal health care, the unavailability of prenatal HIV testing, and the high cost and complexity of the recommended regimen. Researchers need to build upon the findings of developed countries to identify feasible, effective, and implementable interventions to reduce the vertical transmission of HIV as well as to prevent HIV infection among women and to protect the health of HIV-infected women in Africa. Rates and timing of vertical HIV transmission, risk factors associated with vertical HIV transmission, and prevention interventions are discussed.

In 2011, over 10.1 million people were held in prisons around the world. HIV prevalence is elevated in prison and this is due to the over representation of people who inject drugs (PWID). Yet HIV prevention programs for PWID are scarce in the prison setting. With a high proportion of drug users and few prevention programs, HIV transmission occurs and sometimes at an alarming rate. This commentary focuses primarily on drug users in prison; their risk behaviours and levels of infection. It also comments on the transmission of HIV including outbreaks and the efforts to prevent transmission within the prison setting. The spread of HIV in prison has substantial public health implications as virtually all prisoners return to the community. HIV prevention and treatment strategies known to be effective in community settings, such as methadone maintenance treatment, needle and syringe programs, condoms and antiretroviral therapy should be provided to prisoners as a matter of urgency.

This study is a step towards a behavioral intervention to prevent HIV transmission among Chinese internal migrants. To explore important and changeable determinants of condom use and inspect effective and feasible methods to increase condom use for the target population, we conducted a three-round web-based Delphi study among a panel of 62 experts between October 2012 and March 2013. The panelists were purposely selected using a stepwise procedure to represent topic-related areas of expertise. The response rate per round ranges from 21% to 81%. The panelists identified 19 possible determinants of condom use and reported 16 intervention methods they considered successful. They agreed that attitude towards condom use was the most important and changeable determinant, while applying behavioral theory, increasing sexual education and condom access, performing worksite health promotion, detecting risk factors, and working closely with relevant organizations and the government were effective and feasible methods to increase condom use among internal migrants in China. In conclusion, results of this study highlight the importance of attitude in changing condom use and underscore the need to apply behavior theory and integrate multiple educational approaches for developing behavioral HIV prevention interventions targeting internal migrants in China.

Women and girls are especially vulnerable to HIV infection in sub-Saharan Africa, and in some of those countries, prevalence among young women can be up to 3 times higher than among men of the same age. Effective HIV prevention options for women are clearly needed in this setting. Several ARV-based vaginal microbicides are currently in development for prevention of HIV transmission to women and are discussed here. The concept of pre-exposure prophylaxis for the prevention of HIV transmission to women is introduced. PMID:21345763
Background Patients with Tuberculosis (TB) are a vulnerable group for acquiring HIV infection. Therefore, countries with a concentrated HIV epidemic and high prevalence of TB should provide adequate information about HIV prevention to TB patients. Methods We conducted a cross-sectional study to evaluate the level of knowledge on HIV prevention and transmission among newly diagnosed TB patients in Lima, Peru. The survey evaluated knowledge about HIV infection and prevention and was administered before HIV counseling and blood sampling for HIV testing were performed. Results A total of 171 TB patients were enrolled; mean age was 31.1 years, 101 (59%) were male. The overall mean level of knowledge of HIV was 59%; but the specific mean level of knowledge on HIV transmission and prevention was only 33.3% and 41.5%, respectively. Age and level of education correlated with overall level of knowledge in the multivariate model (P-value: 0.02 and <0.001 respectively). Conclusions The study shows inadequate levels of knowledge about HIV transmission and prevention among newly-diagnosed TB patients in this setting, and underscores the need for implementing educational interventions in this population.

Naltrexone is an antagonist that binds tightly to μ-opioid receptors and blocks the subjective and analgesic effects of opioids. It does not produce physiologic dependence and precipitates withdrawal if administered to an opioid dependent person, thus starting it must begin with detoxification. It was first available in the mid-1970s as a 50 mg tablet that blocked opioids for 24-36 h if taken daily, or every 2-3 days at higher doses - for example: 100 mg Monday and Wednesday, 150 mg on Friday. From a pharmacological perspective it worked very well and was hoped to be an effective treatment but results were disappointing due to low patient interest and high dropout followed by relapse. Interest in it waned but rose again in the late 1990's when injecting opioid use and the rapid spread of HIV in the Russian Federation converged with an international interest in reducing the spread of HIV. One result was a series of meetings sponsored by the U.S. National Institute on Drug Abuse (NIDA) and Pavlov State Medical University in St. Petersburg, Russian Federation, on ways to reduce the spread of HIV in that country. Addiction treatment was a clear priority and discussions showed that naltrexone could have a role since agonist treatment is against Russian law but naltrexone is approved and the government funds over 25,000 beds for detoxification, which is the first step in starting naltrexone treatment. These meetings were followed by NIDA studies that showed better compliance to oral naltrexone than in prior U.S. studies with the expected reductions in HIV injecting risk for those that stayed in treatment. These events and findings provided a background and identified an infrastructure for the study that led to FDA approval of extended release injectable naltrexone for preventing relapse to opioid dependence. This paper will briefly review findings from these studies and end with comments on the potential role of extended release naltrexone as a meaningful addition

The Centers for Disease Control and Prevention (CDC) had an annual budget of approximately $327 million to fund health departments and community-based organizations for core HIV testing and prevention programs domestically between 2001 and 2006. Annual HIV incidence has been relatively stable since the year 2000 and was estimated at 48,600 cases in 2006 and 48,100 in 2009. Using estimates on HIV incidence, prevalence, prevention program costs and benefits, and current spending, we created an HIV resource allocation model that can generate a mathematically optimal allocation of the Division of HIV/AIDS Prevention's extramural budget for HIV testing, and counseling and education programs. The model's data inputs and methods were reviewed by subject matter experts internal and external to the CDC via an extensive validation process. The model projects the HIV epidemic for the United States under different allocation strategies under a fixed budget. Our objective is to support national HIV prevention planning efforts and inform the decision-making process for HIV resource allocation. Model results can be summarized into three main recommendations. First, more funds should be allocated to testing and these should further target men who have sex with men and injecting drug users. Second, counseling and education interventions ought to provide a greater focus on HIV positive persons who are aware of their status. And lastly, interventions should target those at high risk for transmitting or acquiring HIV, rather than lower-risk members of the general population. The main conclusions of the HIV resource allocation model have played a role in the introduction of new programs and provide valuable guidance to target resources and improve the impact of HIV prevention efforts in the United States.

HIV prevention trials have demonstrated the effectiveness of a number of behavioral and biomedical interventions. HIV prevention packages are combinations of interventions and offer potential to significantly increase the effectiveness of any single intervention. Estimates of the effectiveness of prevention packages are important for guiding the development of prevention strategies and for characterizing effect sizes before embarking on large scale trials. Unfortunately, most research to date has focused on testing single interventions rather than HIV prevention packages. Here we report the results from agent-based modeling of the effectiveness of HIV prevention packages for men who have sex with men (MSM) in South Africa. We consider packages consisting of four components: antiretroviral therapy for HIV infected persons with CD4 count <350; PrEP for high risk uninfected persons; behavioral interventions to reduce rates of unprotected anal intercourse (UAI); and campaigns to increase HIV testing. We considered 163 HIV prevention packages corresponding to different intensity levels of the four components. We performed 2252 simulation runs of our agent-based model to evaluate those packages. We found that a four component package consisting of a 15% reduction in the rate of UAI, 50% PrEP coverage of high risk uninfected persons, 50% reduction in persons who never test for HIV, and 50% ART coverage over and above persons already receiving ART at baseline, could prevent 33.9% of infections over 5 years (95% confidence interval, 31.5, 36.3). The package components with the largest incremental prevention effects were UAI reduction and PrEP coverage. The impact of increased HIV testing was magnified in the presence of PrEP. We find that HIV prevention packages that include both behavioral and biomedical components can in combination prevent significant numbers of infections with levels of coverage, acceptance and adherence that are potentially achievable among MSM in

Introduction Every new HIV infection is preventable and every HIV-related death is avoidable. As many jurisdictions around the world endeavour to end HIV as an epidemic, missed HIV prevention and treatment opportunities must be regarded as public health emergencies, and efforts to quickly fill gaps in service provision for all people living with and vulnerable to HIV infection must be prioritized. Discussion We present a novel, comprehensive, primary and secondary HIV prevention continuum model for the United States as a conceptual framework to identify key steps in reducing HIV incidence and improving health outcomes among those vulnerable to, as well as those living with, HIV infection. We further discuss potential approaches to address gaps in data required for programme planning, implementation and evaluation across the elements of the HIV prevention continuum. Conclusions Our model conceptualizes opportunities to monitor and quantify primary HIV prevention efforts and, importantly, illustrates the interplay between an outcomes-oriented primary HIV prevention process and the HIV care continuum to move aggressively forward in reaching ambitious reductions in HIV incidence. To optimize the utility of this outcomes-oriented HIV prevention continuum, a key gap to be addressed includes the creation and increased coordination of data relevant to HIV prevention across sectors.

Black women bear the highest burden of HIV infection among US women. Tenofovir/emtricitabine HIV prevention trials among women in Africa have yielded varying results. Ideally, a randomized controlled trial (RCT) among US women would provide data for guidelines for US women's HIV pre-exposure prophylaxis use. However, even among US Black women at high risk for HIV infection, sample size requirements for an RCT with HIV incidence as its outcome are prohibitively high. We propose to circumvent this large sample size requirement by evaluating relationships between HIV incidence and drug concentrations measured among participants in traditional phase 3 trials in high incidence settings - and then applying these observations to drug concentrations measured among at risk individuals in lower incidence settings, such as US Black women. This strategy could strengthen the evidence base to enable Black women to fully benefit from prevention research advances and decrease racial disparities in HIV rates.

This research tested the prediction that reading a preventive brochure leads people to watch a preventive video, and that watching this video in turn leads to an increase in the likelihood of participating in a preventive counseling session. A sample of men and women from a southeastern community in the United States was recruited for a general health survey with the objective of examining participation in HIV-prevention interventions. Unobtrusive measures of exposure to HIV-prevention brochures, an HIV-prevention video, and an HIV-prevention counseling session were obtained. Findings indicated that reading the brochures increased watching the video and that watching the video increased participation in the counseling session. The association between exposure to the video and exposure to the counseling was mediated by expectations that the counseling would be useful. Findings are discussed in terms of the need to ensure exposure to interventions to achieve intervention effectiveness.

This study aimed to build formative knowledge regarding labor migrants' wives' knowledge, attitudes, and behaviors regarding HIV/AIDS risk and protection that would inform developing innovative HIV prevention strategies. This was a collaborative ethnography in Tajikistan that included minimally structured interviews and focused field observations with 30 Tajik wives in Dushanbe married to Tajik male migrant workers currently working in Moscow. The results documented the wives' concerns over their husbands' safety in Moscow and the difficulties of living without husbands. In a male-dominated society, gender norms limit the wives' abilities to protect themselves and their husbands from HIV/AIDS. They have some awareness of HIV/AIDS, but limited abilities to speak about sexual activity, HIV/AIDS, condoms, and HIV testing. Wives do not use condoms with their husbands and depend upon their husband's role as their protector. Wives often turn for support to their "circle of friends" or to a primary care nurse for support, but seldom do these relationships focus on preventing HIV/AIDS. To respond to HIV/AIDS risks amongst the wives of Tajik male migrant workers in Moscow, preventive interventions could build upon migrants' wives' role as the primary family caregiver and their existing sources of social support from women's circles and nurses. The overall intervention strategy could be to expand their role as family caregivers to include HIV/AIDS protection, through enhancing their HIV/AIDS knowledge and prevention skills and negotiation strategies with their husbands.

Since 2001, the U.S. Department of Health and Human Services' Office of Family Planning (OFP), in collaboration with the Minority AIDS Initiative, has provided supplemental grant funds to Title X-funded family planning service delivery sites to expand the availability of human immunodeficiency virus (HIV) prevention services. This work has resulted in three major outcomes: (1) increased institutional capacity for the delivery of HIV-prevention services at Title X family planning service delivery sites, (2) the successful implementation of HIV-prevention services at these sites, and (3) the identification of HIV-positive individuals who were referred to care services. These efforts resulted in a total of 539,667 unduplicated individuals being tested for HIV. These tests resulted in the identification of 1,692 HIV-positive individuals who otherwise may not have been tested for HIV. More than 85% of the HIV-positive cases were detected among clients who self-identified as members of racial/ethnic minority groups. The integration of HIV-prevention services is a feasible and effective strategy for detecting HIV infection among women, including women in racial/ethnic minority groups.

Fires and wildfires represent an element of vulnerability for forests, considering that have now reached a level beyond which further burning would seriously endanger the ecosystem services and their sustainable management. It is fundamental to support fire-fighting Centres by giving them tools, useful to faces future trends; in this sense the first step is to examine technical and operative procedures to evaluate their strong and weak aspects, in collaboration with personnel responsible of risk management, suppression coordination and patrol responsible of direct attack. The aims this work is to identify present elements of strength ad problematic aspects to tuning the wildfire suppression actions to future changes; this is a crucial challenge both for policy and territory planners and managers. Historical investigation lines on forest fire covered the basilar and fundamental dynamics which understanding was necessary to confine and fight the wildfire phenomenon. At the present all the competences, knowledge and connections acquired are translating and including in the Plans, sharing innovative strategies -with the "direct involved actors"- trying to decrease the fire trend. Stakeholders underlined that collaboration between research and territorial Institutions are producing positive results, showing the conceptual rightness and the well-run of the in-progress implementations. The Italian framework of wildfire prevention plans is very peculiar because the Plans related to prevention and active intervention procedure are coincident. Normative, procedural, economic and logistic aspects are considered and handled in the same general document; each year the local structures, designed by the Regions, have in charge the draft of the operative plan, defining and managing the means and patrols distribution and turnover. In the present work 3 Italian Regions (Tuscany, Puglia and Sardinia, with different territorial and vegetation characteristics and affected by different

The HIV/AIDS epidemic has exacted a devastating toll upon Black men who have sex with men (MSM) in the United States, and there is a tremendous need to escalate HIV-prevention efforts for this population. The social context in which Black MSM experience the impact of racism and heterosexism strongly affects their risk for HIV infection; thus, HIV-prevention research focused on Black MSM should focus on contextual and structural factors. There is a pronounced lack of community-level HIV-intervention research for Black MSM, but effective preliminary strategies involve adapting existing effective models and tailoring them to the needs of Black MSM. Future research should develop new, innovative approaches, especially structural interventions, that are specifically targeted toward HIV prevention among Black MSM. PMID:19372510

Background Randomized-trial data on the risks and benefits of antiretroviral therapy (ART) as compared with zidovudine and single-dose nevirapine to prevent transmission of the human immunodeficiency virus (HIV) in HIV-infected pregnant women with high CD4 counts are lacking. Methods We randomly assigned HIV-infected women at 14 or more weeks of gestation with CD4 counts of at least 350 cells per cubic millimeter to zidovudine and single-dose nevirapine plus a 1-to-2-week postpartum "tail" of tenofovir and emtricitabine (zidovudine alone); zidovudine, lamivudine, and lopinavir-ritonavir (zidovudine-based ART); or tenofovir, emtricitabine, and lopinavir-ritonavir (tenofovir-based ART). The primary outcomes were HIV transmission at 1 week of age in the infant and maternal and infant safety. Results The median CD4 count was 530 cells per cubic millimeter among 3490 primarily black African HIV-infected women enrolled at a median of 26 weeks of gestation (interquartile range, 21 to 30). The rate of transmission was significantly lower with ART than with zidovudine alone (0.5% in the combined ART groups vs. 1.8%; difference, -1.3 percentage points; repeated confidence interval, -2.1 to -0.4). However, the rate of maternal grade 2 to 4 adverse events was significantly higher with zidovudine-based ART than with zidovudine alone (21.1% vs. 17.3%, P=0.008), and the rate of grade 2 to 4 abnormal blood chemical values was higher with tenofovir-based ART than with zidovudine alone (2.9% vs. 0.8%, P=0.03). Adverse events did not differ significantly between the ART groups (P>0.99). A birth weight of less than 2500 g was more frequent with zidovudine-based ART than with zidovudine alone (23.0% vs. 12.0%, P<0.001) and was more frequent with tenofovir-based ART than with zidovudine alone (16.9% vs. 8.9%, P=0.004); preterm delivery before 37 weeks was more frequent with zidovudine-based ART than with zidovudine alone (20.5% vs. 13.1%, P<0.001). Tenofovir-based ART was associated

Veterans in need of social services may access many different community agencies within the public and private sectors. Each of these settings has the potential to be a pipeline for attaining needed health, mental health, and benefits services; however, many service providers lack information on how to conceptualize where Veterans go for services within their local community. This article describes a conceptual framework for outreach that uses a service sector segmented approach. This framework was developed to aid recruitment of a provider-based sample of stakeholders (N = 70) for a study on improving access to the Department of Veterans Affairs and community-based suicide prevention services. Results indicate that although there are statistically significant differences in the percent of Veterans served by the different service sectors (F(9, 55) = 2.71, p = 0.04), exposure to suicidal Veterans and providers' referral behavior is consistent across the sectors. Challenges to using this framework include isolating the appropriate sectors for targeted outreach efforts. The service sector segmented approach holds promise for identifying and referring at-risk Veterans in need of services.

There are few peer-reviewed studies of HIV/AIDS-related knowledge, attitudes, beliefs and practices among adolescents in Central America. A population-based cross-sectional survey was conducted among 246 adolescents in León, Nicaragua, where there is reason for concern about a rise in HIV infections. In many respects, León adolescents were typical of those in other Latin American countries, with a mixture of correct and incorrect knowledge about transmission of HIV and sexually transmitted infections, a higher proportion of males than females reporting having had sex or using condoms, and inconsistent condom use. While some sexual attitudes conformed to the ideology of machismo, others did not, providing an opening for prevention interventions. Some dimensions of HIV/AIDS stigma were high, and most adolescents disapproved of same-sex sexual behaviour. Intervention against homosexuality-related stigma is particularly urgent because a concentrated HIV epidemic may be emerging in Nicaragua among men who have sex with men. Personal religious beliefs did not appear to pose a barrier to condom use. In a multivariate model, being out of school was a significant correlate of having had sex and of insufficient HIV/AIDS-related knowledge. Accordingly, HIV prevention interventions must reach adolescents both in and out of school. A multi-component approach to prevention is needed, including programmes based in schools, communities, the mass media and health facilities.
In this article, I report on my decision to undertake a process of elicitation, development, and examination of metaphors for experiences of HIV prevention work in Burma/Myanmar. I cover the theoretical basis to that decision, my rationale for using metaphor elicitation as method when researching the rhetoric and practice of HIV prevention in Burma/Myanmar, the process I used, and some of the resultant metaphors. I also demonstrate that this process resulted in the opening up of a space for talking about HIV prevention that avoided recourse to standard prevention rhetoric, thereby enabling a new and deeper understanding of the gap between this rhetoric and people's actual practice or experience.

Relatively few studies have examined the impact of modifying structural factors on HIV prevention efforts in the United States despite their high potential for lowering HIV prevalence rates. The aim of this study was to identify state-level characteristics of successful HIV prevention implementation. Structured interviews with 73 key informants in 13 rural states identified ‘more successful’ and ‘less successful’ states in HIV prevention. States were compared on demographic, religious, gay community, and funding variables. The 7 more successful states had both a wider variety and more MSM-targeted interventions. Overall funding, degree of epidemic, and “ruralness” were not significantly associated with success. Rather, successful states had less religious and Evangelical Protestant adherents and more ‘gay community’ infrastructure. They also spent a greater proportion of funds contracting community-based organizations and on MSMtargeted programming. Success in HIV prevention varies across rural states. Key demographic, social and economic indicators distinguish success in HIV prevention. PMID:17440806

The impact of a professionally-facilitated peer group intervention for HIV prevention among 400 low income Chilean women was examined using a quasi-experimental design. At three months post-intervention, the intervention group had higher HIV-related knowledge, more positive attitudes towards people living with HIV, fewer perceived condom use barriers, greater self-efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. However, they did not have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries. PMID:22420675

Although pharmacological interventions have been successful in reducing prevention of maternal to child transmission (PMTCT) of HIV, there is concern that complete elimination through this mode of transmission will require other measures. Immunotherapies in infants or pregnant mothers may be able to eradicate this form of transmission. A recent vaccine trial in adults showed encouraging results, but as in most HIV safety and efficacy vaccine trials, the question of MTCT was not addressed. Concentrating transmission studies and vaccine studies in the setting of MTCT offers several advantages. MTCT has a generally reproducible known transmission rate and has been successfully used to assess pharmacological interventions on decreasing transmission. Even in resource poor settings, the infrastructure for neonatal vaccination is already in place. Although rare, both passive and active vaccination trials have been successfully completed in pediatric populations. Unfortunately, little success in affecting MTCT has been shown. Largely, a correlate of protection in any type of transmission, including MTCT, is unknown. Data supports a role for antibodies in effecting strain and transmission during MTCT. The role of antibodies in MTCT is reviewed with a focus on recent passive immunization and considerations for future studies.

Homeless youth are prone to Human Immunodeficiency Virus (HIV) due to their engagement in high risk behavior such as unprotected sex, sex under influence of drugs, etc. Many non-profit agencies conduct interventions to educate and train a select group of homeless youth about HIV prevention and treatment practices and rely on word-of-mouth spread of information through their social network. Previous work in strategic selection of intervention participants does not handle uncertainties in the social network’s structure and evolving network state, potentially causing significant shortcomings in spread of information. Thus, we developed PSINET, a decision support system to aid the agencies in this task. PSINET includes the following key novelties: (i) it handles uncertainties in network structure and evolving network state; (ii) it addresses these uncertainties by using POMDPs in influence maximization; and (iii) it provides algorithmic advances to allow high quality approximate solutions for such POMDPs. Simulations show that PSINET achieves ~60% more information spread over the current state-of-the-art. PSINET was developed in collaboration with My Friend’s Place (a drop-in agency serving homeless youth in Los Angeles) and is currently being reviewed by their officials. PMID:27642227

HIV-related stigma, discrimination, and homophobia impede community based efforts to combat HIV disease among Latino and African American gay and bisexual men. This commentary highlights ways to address these social biases in communities of color in Los Angeles from the perspectives of staff from HIV prevention programs. Information was collected from HIV prevention program staff participating in a two-day symposium. The outcomes from the symposium offer strategies for developing and implementing HIV prevention services for Latino and African American gay and bisexual men, which include: 1) addressing social biases present in a community that can hinder, and even prohibit, utilization of effective HIV prevention programs; 2) recasting HIV prevention messages in a broader social or health context; 3) developing culturally appropriate HIV prevention messages; 4) exploring new modalities and venues for delivering HIV prevention messages that are appropriate for gay and bisexual men of color and the communities in which they live; and 5) broadening the target of HIV prevention services to include service providers, local institutions and agencies, and the community at-large. These strategies underscore the need to consider the social and contextual factors of a community when designing and implementing HIV prevention programs. PMID:16283834

As a population, persons with serious mental illness (SMI) have an elevated risk for HIV infection. However, relatively little is known about how the risk of HIV has affected their lives, how persons with SMI evaluate their HIV risk, and what preventive measures they undertake. Furthermore, relatively little is known about community-based HIV prevention for persons with SMI as most interventions have been restricted to clinical settings. This report presents findings on the HIV-related experiences of persons with SMI living in supportive housing programs, one possible setting for implementing community-based HIV prevention with this population. The qualitative investigation interviewed 41 men and women living in five supportive housing programs. In-depth, qualitative interviews elicited discussion of research participants' (a) experiences with HIV, (b) knowledge about HIV and HIV prevention, (c) assessments of their own risk, (d) descriptions of how they apply their prevention knowledge, and (e) reports of barriers for HIV prevention. Research participants describe social networks that have substantial contact with persons affected by HIV. However, contrary to some expectations of persons with SMI, research participants report using HIV prevention knowledge in negotiating their risk of contracting HIV. The implications of these findings are discussed in terms of their relevance for implementing community-based HIV prevention for persons with SMI.

The lie has been presented as a performance that protects identities against moral judgment in the context of power imbalances. We explore this assertion from the perspective of a pre-exposure prophylaxis trial to prevent HIV for African women in South Africa, in which context biological evidence of widespread lying about product adherence was produced, resulting in a moral discourse that opposed altruistic and selfish motivations. In this article, we seek to understand the meaning of the lie from the perspective of women trial participants. Seeing the trial as representing a hopeful future, and perfect adherence as sustaining their investment in this, participants recited scripted accounts of adherence and performed the role of the perfect adherer, while identifying other participants as dishonest. Given that clinical trials create moral orders and adherence is key to this, we argue that women embraced the apparatus of the clinical trial to assert their moral subjectivities. PMID:26575611

Over the past decade, a wealth of experimental evidence has accumulated supporting the importance of Fc receptor (FcR) ligation in antibody-mediated pathology and protection in many disease states. Here we present the diverse evidence base that has accumulated as to the importance of antibody effector functions in the setting of HIV prevention and therapy, including clinical correlates, genetic associations, viral evasion strategies, and a rapidly growing number of compelling animal model experiments. Collectively, this work identifies antibody interactions with FcR as important to both therapeutic and prophylactic strategies involving both passive and active immunity. These findings mirror those in other fields as investigators continue to work toward identifying the right antibodies and the right effectors to be present at the right sites at the right time.

The Information-Motivation-Behavioral Skills model examines factors that are used to initiate and maintain sexual and reproductive health promotion behaviors. The present study evaluated the association among these constructs as it is applied to sexually active heterosexual adults with steady partners, using a Structural Equation Modeling approach. At the same time, it was analyzed if the same model structure could be generalized to two samples of participants that produced the results following two different formats for data collection. Two-hundred ninety one participants completed the Information-Motivation-Behavioral Skills Questionnaire (Spanish version), and 756 participants completed an Internet version on the instrument. The proposed model fits the data for both groups, supporting a predictive and positive relationship among all of the latent variables, with Information predicting Motivation, and Motivation therefore predicting Behavioral Skills. The findings support the notion that there are important issues that need to be addressed when promoting HIV prevention. PMID:23243320

The current study aimed to identify the sources of HIV prevention information for female sex workers in Beijing and assess the associations between levels of mass media exposure of HIV/AIDS prevention information and HIV/AIDS knowledge as well as condom use-related attitudes, beliefs, and behaviors. Cross-sectional data were collected from 359 female sex workers in Beijing, China. Chi-square tests and one-way ANOVA tests were employed. Female sex workers sampled in Beijing were more likely to obtain HIV/AIDS prevention information from television and street posters than radio and the Internet. However, a higher level of exposure to and a lasting impression on online information were significantly associated with a higher level of condom use self-efficacy and more consistent condom use among the participants. Exposure to HIV/AIDS prevention information delivered by radio, street posters, and the Internet was found to be associated with sexual communication about HIV or condom use with sexual partners. Overall, this study provides preliminary evidence of the utility of various mass media outlets in delivering HIV/AIDS prevention information among female sex workers in China. Future studies are needed to systematically examine the effectiveness of mass media-based prevention education on HIV/AIDS related attitudes and behaviors among female sex workers and other populations in China.

Identifying venues where women meet sexual partners, particular partners who increase women's risk of acquiring HIV, could inform prevention efforts. We categorized venues where women enrolled in HPTN 064 reported meeting their last three sex partners as: (1) Formal, (2) Public, (3) Private, and (4) Virtual spaces. We used multinomial logistic regression to assess the association between these venues and women's individual characteristics and reports of their partners' HIV risk characteristics. The 2099 women reported meeting 3991 partners, 51 % at Public, 30 % Private, 17 % Formal and 3 % at Virtual venues. Women meeting partners at Formal venues reported more education and condom use than women meeting partners at other venues. Fewer partners met through Formal venues had “high” risk characteristics for HIV than through other venues and hence may pose less risk of HIV transmission. HIV prevention interventions can help women choose partners with fewer risk characteristics across all venue types. PMID:25863466

Cervical cancer is the leading cause of cancer related deaths among women. Each year there are approximately 250,000 deaths; most of which occurred in Sub-Saharan Africa, South Asia, and Latin America. The purpose of this report is to examine key stakeholders experience and knowledge of HPV and cervical cancer, examine their experiences with the current cervical cancer screening and treatment policy, and identify barriers and facilitating factors to vaccine implementation and uptake. Fifteen indepth interviews were conducted with key stakeholders in Cape Town and Johannesburg, South Africa. The interviews revealed several key findings including: 1) knowledge about HPV and cervical cancer varied across participants, 2) knowledge about cervical cancer was also mixed while knowledge about the relationship between HPV and cervical cancer was low among participants. Our findings indicate that key stakeholders are concerned about women's health and wellbeing. In addition, they believe that the government, families, and the media need to play a prominent role in prevention efforts.

HIV-prevention intervention effectiveness depends on understanding whether clients with highest need for HIV-prevention counseling accept it. With this objective, a field study with a high-risk community sample from the southeastern United States (N = 350) investigated whether initial knowledge about HIV, motivation to use condoms, condom-use-relevant behavioral skills, and prior condom use correlate with subsequent acceptance of an HIV-prevention counseling session. Ironically, participants with high (vs. low) motivation to use condoms, high (vs. low) condom-use-relevant behavioral skills, and high (vs. low) prior condom use were more likely to accept the HIV-prevention counseling. Moreover, the influence of motivation to use condoms, condom-use-relevant behavioral skills, and prior condom use on acceptance of the counseling was mediated by expectations that the counseling session would be useful. Methods to reduce barriers to recruitment of clients for counseling programs are discussed. PMID:19634960

Acquired immune deficiency syndrome has been one of the most devastating epidemics of the last century. The current estimate for people living with the HIV is 36.9 million. Today, despite availability of potent and safe drugs for effective treatment, lifelong therapy is required for preventing HIV re-emergence from a pool of latently infected cells. However, recent evidence show the importance to expand HIV testing, to offer antiretroviral treatment to all infected individuals, and to ensure retention through all the cascade of care. In addition, circumcision, pre-exposure prophylaxis, and other biomedical tools are now available for included in a comprehensive preventive package. Use of all the available tools might allow cutting the HIV transmission in 2030. In this article, we review the status of the epidemic, the latest advances in prevention and treatment, the concept of treatment as prevention and the challenges and opportunities for the HIV cure agenda.

Despite efforts to increase access to HIV testing and counseling services, population coverage remains low. As a result, many people in sub-Saharan Africa do not know their own HIV status or the status of their sex partner(s). Recent evidence, however, indicates that as many as half of HIV-positive individuals in ongoing sexual relationships have an HIV-negative partner and that a significant proportion of new HIV infections in generalized epidemics occur within serodiscordant couples. Integrating couples HIV testing and counseling (CHTC) into routine clinic- and community-based services can significantly increase the number of couples where the status of both partners is known. Offering couples a set of evidence-based interventions once their HIV status has been determined can significantly reduce HIV incidence within couples and if implemented with sufficient scale and coverage, potentially reduce population-level HIV incidence as well. This article describes these interventions and their potential benefits.

Successes in HIV prevention efforts in the U.S. have resulted in drastic reductions in the number of new infections in the U.S. among white gay men and injection drug users, a stabilization in overall annual rates of new HIV infections, and near eradication of mother-to child transmission of HIV. Despite this remarkable progress, the proportion of AIDS cases in women has slowly, quietly, and steadily increased from 7% in 1985 to 25% in 2008. The fact the prevention efforts have not reduced HIV spread among women suggests that targeting the individual behaviors of women to prevent HIV acquisition is not a sufficiently effective public health strategy. Interventions that more broadly address the needs of women and their families, and address the contextual factors in which HIV risk occurs are more likely to lead to measurable and sustainable progress. Over the past 30 years, we have seen the U.S. HIV epidemic in women become similar to patterns of HIV risk among women in the developing world. In 2009, 85% of women who acquired HIV became infected through sex with a man and the majority (83%) of them were non-white women. Efforts to understand these immense disparities and create gender-responsive strategies must be a priority within our National HIV/AIDS Strategy.

Men who have sex with men (MSM) are at disproportionate risk for HIV infection globally. The past 5 years have seen considerable advances in biomedical interventions to reduce the risk of HIV infection. To be impactful in reducing HIV incidence requires the rapid and expansive scale-up of prevention. One mechanism for achieving this is technology-based tools to improve knowledge, acceptability, and coverage of interventions and services. This review provides a summary of the current gap in coverage of primary prevention services, how technology-based interventions and services can address gaps in coverage, and the current trends in the development and availability of technology-based primary prevention tools for use by MSM. Results from agent-based models of HIV epidemics of MSM suggest that 40-50 % coverage of multiple primary HIV prevention interventions and services, including biomedical interventions like preexposure prophylaxis, will be needed to reduce HIV incidence among MSM. In the USA, current levels of coverage for all interventions, except HIV testing and condom distribution, fall well short of this target. Recent findings illustrate how technology-based HIV prevention tools can be used to provide certain kinds of services at much larger scale, with marginal incremental costs. A review of mobile apps for primary HIV prevention revealed that most are designed by nonacademic, nonpublic health developers, and only a small proportion of available mobile apps specifically address MSM populations. We are unlikely to reach the required scale of HIV prevention intervention coverage for MSM unless we can leverage technologies to bring key services to broad coverage for MSM. Despite an exciting pipeline of technology-based prevention tools, there are broader challenges with funding structures and sustainability that need to be addressed to realize the full potential of this emerging public health field.

Understanding barriers to accepting HIV-prevention counseling among vulnerable populations is of critical importance, as prevention efforts can only have a public health impact if high-risk populations are willing to enroll. A correlational field study was conducted in a health care setting with a high-risk community sample (N = 350) to determine if number of sex partners and alcohol consumption predict acceptance of an invitation to take part in HIV-prevention counseling. Findings indicated that participants engaging in the least risky behavior (i.e. individuals reporting no alcohol consumption and few sex partners) were more likely to accept an offer to receive HIV-prevention counseling. Moreover, heavy drinking was associated with decreased exposure to HIV-prevention counseling, regardless of the number of sex partners reported (b = .12, p > .05). Given associations between heavy drinking and sexual risk taking, finding ways to increase exposure to HIV-prevention counseling programs among heavy drinkers could serve a vital public health function.

Predominantly Spanish-speaking Latino men who have sex with men (MSM) and their same-sex partners continue to be at high risk for HIV and STIs. Behavioral research has identified how relationship dynamics for male couples are associated with sexual risk behavior. Connect ‘n Unite (CNU), an evidence-based HIV/STI prevention intervention originally created for Black MSM and their same-sex partners, was adapted for predominantly Spanish-speaking Latino MSM and their same-sex partners on the assumption that its key elements would be translatable while its efficacy would be retained. A systematic adaptation process utilizing qualitative methods was used, including intervention adaptation sessions with 20 predominantly Spanish-speaking Latino gay couples and 10 health service providers. The process included five steps: (1) engaging community stakeholders, (2) capturing the lived experiences of Latino gay couples, (3) identifying intervention priorities, (4) integrating the original intervention’s social cognitive theory into a relationship-oriented, ecological framework for Latino gay couples, and (5) adapting intervention activities and materials. The adapted intervention, which we called Latinos en Pareja or Latinos in a Relationship, incorporates elements that effective HIV prevention interventions share, including: a solid theoretical foundation; emphasis on increasing risk reduction norms, sexual communication skills and social support for protection; and guidance on how to utilize available, culturally and linguistically appropriate services. The systematic adaptation approach used for a couples-based HIV prevention intervention also can be employed by other researchers and community stakeholders to adapt evidence-based interventions that promote wellness, linkage to care, and disease prevention for populations not originally targeted.

Substantially engaging stakeholders in research involves making extensive changes to the full life cycle of research, from the initial stage of selecting research priorities to the final stages of dissemination and implementation. Recent scholarship has explored logistical and methodological challenges, including the time, training and resources required for engagement. However, inadequate attention has been given to the intended ends or goals of engagement - what do we want engagement to achieve? An examination of historical case studies can yield important insights regarding engagement and its intended ends. Using historical perspective methods, we explore how clarity about the ends of engagement can inform the design of engagement efforts and lead to better outcomes. We present several lessons for improving stakeholder-engaged research.

Using popular culture to engage students in discussions of HIV prevention is a nontraditional approach that may complement current prevention efforts and enhance the ability to reach youth who are at high risk of contracting HIV and other sexually transmitted infections. Hip-hop or rap music is the dominant genre of music among adolescents, especially Black and Latino youth who are disproportionately impacted by HIV and AIDS. This paper describes the rationale and development of the Reducing HIV and AIDS through Prevention (RHAP) program, a school-based program that uses hip-hop/rap music as a vehicle for raising awareness among adolescents about HIV/AIDS. Constructs from the Social Cognitive Theory and the Sexual Script Theory were used in developing the program. It was piloted and evaluated among 26 middle school students in East Harlem, New York. The lessons learned from a formative evaluation of the program and the implications for developing other programs targeting public health problems are discussed. The RHAP program challenges the traditional pedagogue-student paradigm and provides an alternative approach to teaching about HIV prevention and awareness.

The advent of pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) as means of HIV prevention raises issues of justice concerning how most fairly and equitably to apportion resources in support of the burgeoning variety of established HIV treatment and prevention measures and further HIV research, including HIV vaccine research. We apply contemporary approaches to social justice to assess the ethical justification for allocating resources in support of HIV vaccine research given competing priorities to support broad implementation of HIV treatment and prevention measures, including TasP and PrEP. We argue that there is prima facie reason to believe that a safe and effective preventive HIV vaccine would offer a distinct set of ethically significant benefits not provided by current HIV treatment or prevention methods. It is thereby possible to justify continued support for HIV vaccine research despite tension with priorities for treatment, prevention, and other research. We then consider a counter-argument to such a justification based on the uncertainty of successfully developing a safe and effective preventive HIV vaccine. Finally, we discuss how HIV vaccine research might now be ethically designed and conducted given the new preventive options of TasP and PrEP, focusing on the ethically appropriate standard of prevention for HIV vaccine trials.

Men who have sex with men (MSM) have been substantially affected by HIV epidemics worldwide. Epidemics in MSM are re-emerging in many high-income countries and gaining greater recognition in many low-income and middle-income countries. Better HIV prevention strategies are urgently needed. Our review of HIV prevention strategies for MSM identified several important themes. At the beginning of the epidemic, stand-alone behavioural interventions mostly aimed to reduce unprotected anal intercourse, which, although somewhat efficacious, did not reduce HIV transmission. Biomedical prevention strategies reduce the incidence of HIV infection. Delivery of barrier and biomedical interventions with coordinated behavioural and structural strategies could optimise the effectiveness of prevention. Modelling suggests that, with sufficient coverage, available interventions are sufficient to avert at least a quarter of new HIV infections in MSM in diverse countries. Scale-up of HIV prevention programmes for MSM is difficult because of homophobia and bias, suboptimum access to HIV testing and care, and financial constraints. PMID:22819659

Abstract Persons living with HIV (PLWH) are living longer, remaining sexually active, and may continue risky sexual behaviors. As such, it is crucial for providers to ask all HIV-positive patients about behaviors related to HIV transmission and STD acquisition. The “Ask, Screen, Intervene” (ASI) curriculum was developed to increase provider knowledge, skills, and motivation to incorporate risk assessment and prevention services into the care of PLWH. The ASI curriculum was delivered to 2558 HIV-care providers at 137 sites between September 30, 2007 and December 31, 2010. Immediately post-training, participants self-reported significant gains in perceived confidence to demonstrate ASI knowledge and skills (p<0.001) and 89% agreed they would update practices as a result of the training. Three to six months post-training, 320 participants who served PLWH or supervised HIV-care providers self-reported more frequently performing ASI skills (p<0.001), and 71% self-reported greater perceived confidence than before training to perform those skills (p<0.001). Limitations include self-reported measures and a 30% response rate to the 3–6 month follow-up survey. Our findings suggest that a well-coordinated training program can reach a national audience of HIV-care providers, significantly increase self-reported capacity to incorporate HIV/STD prevention into the care of PLWH, and increase implementation of national recommendations.

Through a comprehensive literature search, the authors of this systematic review identified 21 articles focused on primary prevention of HIV/AIDS for adults aged 50 and over. Three major challenges to providing HIV/AIDS education for older adults include health professionals' ageism, older adults' reluctance to discuss sexuality, and their misconception of their HIV risk. Clinical guidelines for social workers, nurses, and physicians identified the importance of sharing information and assessing risk, considering cultural diversity, and devising creative delivery strategies. Three models of HIV/AIDS education include group education programs delivered by social workers or other health professionals, peer education models, and one-on-one early intervention models including HIV/AIDS testing. Additional outreach and research on HIV/AIDS prevention among older adults is needed.

The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, and thus reduce the HIV health disparities that exist among ethnic minority youth and other segments of the U.S. population. This article calls for a paradigm shift to develop, evaluate, and disseminate interventions that target upstream/macro-level factors or that, at a minimum, integrate both a macro and individual level perspective. The article also discusses the challenges in developing and evaluating such interventions. Psychologists and other behavioral scientists can play a critical role in reducing the impact of HIV on ethnic minority youth by integrating macro-level approaches to future HIV prevention strategies.

Greater understanding of barriers to risk reduction among incarcerated HIV+ persons reentering the community is needed to inform culturally tailored interventions. This qualitative study elicited HIV prevention-related information, motivation and behavioral skills (IMB) needs of 30 incarcerated HIV+ men and women awaiting release from state prison. Unmet information needs included risk questions about viral loads, positive sexual partners, and transmission through casual contact. Social motivational barriers to risk reduction included partner perceptions that prison release increases sexual desirability, partners’ negative condom attitudes, and HIV disclosure-related fears of rejection. Personal motivational barriers included depression and strong desires for sex or substance use upon release. Behavioral skills needs included initiating safer behaviors with partners with whom condoms had not been used prior to incarceration, disclosing HIV status, and acquiring clean needles or condoms upon release. Stigma and privacy concerns were prominent prison context barriers to delivering HIV prevention services during incarceration. PMID:21553252

With the continuing march of the AIDS epidemic and little hope for an effective vaccine in the near future, work to develop a topical strategy to prevent HIV infection is increasingly important. This stated, the track record of large scale "microbicide" trials has been disappointing with nonspecific inhibitors either failing to protect women from infection or even increasing HIV acquisition. Newer strategies that target directly the elements needed for viral entry into cells have shown promise in non-human primate models of HIV transmission and as these agents have not yet been broadly introduced in regions of highest HIV prevalence, they are particularly attractive for prophylaxis. We review here the agents that can block HIV cellular entry and that show promise as topical strategies or "virustats" to prevent mucosal transmission of HIV infection PMID:19094217

The black church is influential in shaping health behaviors within African-American communities, yet few use evidence-based strategies for HIV prevention (abstinence, monogamy, condoms, voluntary counseling and testing, and prevention with positives). Using principles of grounded theory and interpretive description, we explored the social construction of HIV prevention within black Baptist churches in North Carolina. Data collection included interviews with church leaders (n = 12) and focus groups with congregants (n = 7; 36 participants). Analytic tools included open coding and case-level comparisons. Social constructions of HIV/AIDS prevention were influenced by two worldviews: public health and church-based. Areas of compatibility and incompatibility exist between the two worldviews that inform acceptability and adaptability of current evidence-based strategies. These findings offer insight into ways to increase the compatibility of evidence-based HIV prevention strategies within the black Baptist church context. PMID:24643141

It is a hard work to develop an hightly effective cure and prevention of HIV/AIDS. The widespread used of some therapy approaches such as highly active anti retroviral therapy (HAART) has improved life quality and span of infected individuals. However, some limitations of these approaches prevent them achieving further advancement. Recent research on drug delivery approaches indicates that engineered nanosystems may bring positive effect on the improvement of current antiretroviral therapy. Furthermore, the basic researches of nanotechnology- based systems which prevent HIV transmission have been started. Therefore, nanotechnology may become a potential approach in the field of HIV/AIDS treatment and prevention. This chapter reviews the latest advancement in the field of nanotechnology-based systems which improve the fields of HIV/AIDS treatment and prevention.

Abstract: Worldwide, transgender women are at disproportionately higher risk of HIV infection, with the primary mode of infection being condomless anal intercourse. Although very few HIV prevention interventions have been developed and tested specifically for transgender women, growing evidence suggests that behavioral HIV risk reduction interventions for other marginalized groups are efficacious. We outline the current state of knowledge and areas in need of further development in this area. PMID:27429186

The symposium "HIV/AIDS: Vaccines and Alternate Strategies for Treatment and Prevention" brought together HIV vaccine researchers to discuss the latest developments in the field. From basic discoveries in virus diversity and mechanisms of neutralization by antibodies to nonhuman primate research and clinical trials of vaccine candidates in volunteers, scientists are making great strides in understanding the mechanisms that may protect against HIV and pathways to achieve this protection through vaccination.

This paper analyses developments and debates regarding legal and human rights issues relevant to the Australian HIV response in the context of treatment as prevention (TasP). A refocusing of prevention priorities on individual responsibilities to 'test and treat' without regard to the legal and human rights context is, we argue, problematic. The paper maintains that the justification of testing and treating for the greater good risks eroding the foundations of a human rights-based approach to HIV prevention, and that the TasP agenda as presently conceived may divert attention from pressing law reform issues relating to sex work, illicit drug use, and criminalization of HIV transmission.

In November 2010, the iPrEx study reported that preexposure prophylaxis (PrEP) with daily tenofovir disoproxil fumarate/emtricitabine reduced HIV infections by 44% among men who have sex with men and subsequent trials corroborated efficacy among heterosexual men and women. During regularly scheduled follow-up visits from January to March 2011, participants in an ongoing phase 2b vaccine efficacy trial completed an anonymous Web survey about PrEP. Among 376 respondents, 17% reported they were very likely to use PrEP in the next year. Nonwhite participants were more likely to use PrEP. Among those with some level of interest, intent to use PrEP was greatest if the drug were available through the clinical trial or health insurance. Most (91%) believed taking PrEP would not change their willingness to stay in the vaccine trial and few thought it would affect recruitment. As key stakeholders, currently enrolled trial participants can offer vital input about emerging prevention technologies that may affect the design of future HIV vaccine and nonvaccine prevention trials.

Aim To analyse trends in HIV testing, serial HIV prevalence and HIV incidence among people who underwent voluntary testing in a Center for AIDS Prevention in Valencia, Spain. Methods Open cohort study including all subjects who went to the Center for AIDS Prevention from 1988 to 2003. Information on sociodemographic variables and HIV test results was collected. Serial prevalence and incidence rates were calculated, and joinpoint regression was used to identify changes in trends over time. Results 21 241 subjects were analysed; 67% men, 27% injecting drug users (IDUs), 43% heterosexuals and 13% men who have sex with men (MSM). From 1988 to 1990, IDUs accounted for 57% of clinic attenders, decreasing to 14% by 1997–2003, accompanied by an increase in heterosexuals. Overall, HIV prevalence for the whole period was 15%, dropping from 35% to <10% after 1999 and to 3% by 2003, when HIV prevalence was 26% in IDUs, 6% in MSM and 2% in heterosexuals. Total HIV incidence was 2.5%. From 1988 to 1990, HIV incidence ranged from 6% to 8%, and a gradual and progressive decline observed from 1990 onwards. From 1995 onwards, HIV incidence was <2%. The highest incidence rate is seen in IDUs, 7–12% in the first period and 4–5% at the end. Among MSM, a change in the decreasing trend is seen by 1998, and increases in incidence are detected by 2002–3. Conclusions Serial HIV prevalence has markedly decreased from 1988 in all transmission categories, although it is still high. With regard to HIV incidence, the drop has been marked too, although a worrying increase, that requires further follow‐up, has been detected in MSM in the past 2 years. PMID:16757515

Public health responses to HIV epidemics have long relied on epidemiological modelling analyses to help prospectively project and retrospectively estimate the impact, cost-effectiveness, affordability, and investment returns of interventions, and to help plan the design of evaluations. But translating model output into policy decisions and implementation on the ground is challenged by the differences in background and expectations of modellers and decision-makers. As part of the PLoS Medicine Collection "Investigating the Impact of Treatment on New HIV Infections"--which focuses on the contribution of modelling to current issues in HIV prevention--we present here principles of "best practice" for the construction, reporting, and interpretation of HIV epidemiological models for public health decision-making on all aspects of HIV. Aimed at both those who conduct modelling research and those who use modelling results, we hope that the principles described here will become a shared resource that facilitates constructive discussions about the policy implications that emerge from HIV epidemiology modelling results, and that promotes joint understanding between modellers and decision-makers about when modelling is useful as a tool in quantifying HIV epidemiological outcomes and improving prevention programming.

HIV-1, herpes simplex virus type 2 (HSV-2), and human papillomavirus (HPV), among other sexually transmitted infections, represent a major burden for global health. Initial insights into the mucosal transmission of these viral pathogens have raised optimism with regard to the rapid generation of protective vaccines. Nevertheless, setbacks for HIV-1 and HSV-2 vaccines have seriously challenged the initial enthusiasm. Recently, two new vaccines that efficiently prevented HPV infection have renewed the hope that vaccinal prevention of viral mucosal sexually transmitted infections is possible. HIV-1 and HSV-2 differ from HPV, and each virus needs to be tackled with a distinct approach. However, vaccines are not the only possible answer. Topically applied agents (microbicides) are an attractive alternative in the prevention of HIV-1 and HSV-2 mucosal transmission. Progress in understanding the mechanisms of genital transmission of HIV-1 and HSV-2 is required for successful vaccine or microbicide candidates to emerge from current approaches.

We present a model for HIV-related behaviors that emphasizes the dynamic and social nature of the structural factors that influence HIV prevention and detection. Key structural dimensions of the model include resources, science and technology, formal social control, informal social influences and control, social interconnectedness, and settings. These six dimensions can be conceptualized on macro, meso, and micro levels. Given the inherent complexity of structural factors and their interrelatedness, HIV prevention interventions may focus on different levels and dimensions. We employ a systems perspective to describe the interconnected and dynamic processes of change among social systems and their components. The topics of HIV testing and safer injection facilities (SIFs) are analyzed using this structural framework. Finally, we discuss methodological issues in the development and evaluation of structural interventions for HIV prevention and detection.

As the reach of the Internet and cell phones increases, their use as health intervention and prevention tools has been increasingly researched. To identify recent advances in technology-based HIV prevention and intervention research, we conducted a literature search in the Spring of 2007. Only a handful of articles have been published in the last year describing evaluations of technology-based HIV programs. Nonetheless, many programs have recently been funded and are being developed or imminently evaluated. Results to date suggest the Internet and cell phones are feasible technologies to deliver HIV prevention and intervention programs for some target populations. Opportunities for future research are identified, including the development of programs for populations other than men who have sex with men who also are at risk for HIV (eg, adolescents, elderly), the integration of advances from other fields, examination of the potential for using text messaging to affect HIV behavior change, and applications of Internet-based programs in developing countries.

The objective of this paper is to review the current status of drug use and HIV/AIDS prevention for drug users in China and provide scientific evidence for HIV/AIDS prevention and control in drug users. Literature and articles related to drug abuse in China, as well as the results of prevention efforts and successful cases regarding HIV/AIDS prevention in drug users, are reviewed. Lessons learned are drawn out for the future improvement of work and the sustainable development of treatment programs. The number of drug users in China is increasing. Even though the number of opioid-type drug users is growing more slowly than in the past, the number of amphetamine-type stimulant users has increased sharply. It has been proven that methadone maintenance treatment and syringe exchange programs gradually and successfully control HIV/AIDS transmission in drug users. However, it is necessary to enhance these prevention methods and expand their coverage. In addition, the strengthening of antiretroviral therapy (ART) treatment for HIV-infected drug users is crucial for HIV/AIDS prevention and control. The rapidly growing number of amphetamine-type stimulant users, along with their high-risk behavior, poses a hidden danger of greater HIV/AIDS transmission through sexual intercourse in the near future.

This paper raises the question of how knowledge creation is organized in the area of HIV prevention and how this concatenation of expertise, resources, at-risk people and viruses shapes the knowledge used to impede the epidemic. It also seeks to trouble the discourses of biomedical pre-eminence in the field of HIV prevention by examining the claim for treatment as prevention, looking at evidence constructed through the biomedical frame and through the lens of the sociology of science. These questions lie within a larger socio-historical context of lagging worldwide attention and funding to prevention in the HIV area and, in particular, neglect of populations at greatest risk. Much contemporary HIV prevention research relies on a population science divided over an epistemic fault line from the communities and individuals who must make sense of the intrusion of a life-threatening disease into their pursuit of pleasure and intimacy. There are, nevertheless, lessons to be learned from prevention success stories among sex workers, injection drug users, and gay and bisexual men. The success stories point to a need for a robust social science agenda that examines: the ways that people are socially organized and networked; the popular strategies and folk wisdoms developed in the face of HIV risk; socio-historical movement of sexual and drug cultures; the dynamics of popular mobilization to advance health; the institutional sources of HIV discourses; and popular understandings of HIV technologies and messages.

The aim of the cross-sectional study was to understand gender differences in HIV/AIDS preventive self-efficacy among Taiwanese adolescents. Self-administered questionnaires were used to measure HIV/AIDS preventive self-efficacy and covariates (age, substance use, and sexual experiences). Data were collected from 734 Taiwanese high school adolescents aged 16 to 18 years. Descriptive statistic analyses, t-test, and ANCOVA were utilized to analyze data. The results indicate significant differences exist between genders in HIV/AIDS preventive self-efficacy among Taiwanese adolescents. Compared to the males, female adolescents were found having significantly higher HIV/AIDS preventive self-efficacy related to refusing sexual intercourse, condom use, and questioning potential sexual partners than those who are males. While controlling age, sexual experience, and substance use, female Taiwanese adolescents also had higher HIV/AIDS preventive self-efficacy than those who are males. The findings suggest the importance of addressing gender differences in HIV/AIDS preventive self-efficacy when developing HIV reduction programs for Taiwanese adolescents.

Various studies have reported that university students, who are mostly young people, rarely use existing HIV/AIDS preventive methods. Although studies have shown that young university students have a high degree of knowledge about HIV/AIDS and HIV modes of transmission, they are still not utilising the existing HIV prevention methods and still engage in risky sexual practices favourable to HIV. Some variables, such as awareness of existing HIV/AIDS prevention methods, have been associated with utilisation of such methods. The study aimed to explore factors that influence use of existing HIV/AIDS prevention methods among university students residing in a selected campus, using the Health Belief Model (HBM) as a theoretical framework. A quantitative research approach and an exploratory-descriptive design were used to describe perceived factors that influence utilisation by university students of HIV/AIDS prevention methods. A total of 335 students completed online and manual questionnaires. Study findings showed that the factors which influenced utilisation of HIV/AIDS prevention methods were mainly determined by awareness of the existing university-based HIV/AIDS prevention strategies. Most utilised prevention methods were voluntary counselling and testing services and free condoms. Perceived susceptibility and perceived threat of HIV/AIDS score was also found to correlate with HIV risk index score. Perceived susceptibility and perceived threat of HIV/AIDS showed correlation with self-efficacy on condoms and their utilisation. Most HBM variables were not predictors of utilisation of HIV/AIDS prevention methods among students. Intervention aiming to improve the utilisation of HIV/AIDS prevention methods among students at the selected university should focus on removing identified barriers, promoting HIV/AIDS prevention services and providing appropriate resources to implement such programmes.

The aim of the present study was to describe the development and evaluation of a program designed to prevent HIV/AIDS. A participatory action research (PAR) approach was used in collaboration with ten schools in Chiang Mai Province, Thailand, to develop a youth- adult partnership with schools (YAPS) model. The YAPS model included curricula using participatory learning experiences, edutainment approaches, and skills building strategies for enhancing youth leaders'capacities. Results showed that the YAPS model was effective in leadership role preparation and in empowering youth leaders to undertake activities on their own, initiate creativity and share knowledge on sexuality education and HIV prevention messages with students in schools. The use of partnerships and the participatory process mobilized parents, teachers, and school administrators to play a proactive role in sexuality education and HIV prevention for early adolescents in schools, resulting in the integration of the program into the school system.

African American young men who have sex with men and transgender persons are at elevated risk for HIV infection. House and Ball communities, networks of mostly African American gay, bisexual and transgender individuals who compete in modeling and dance, represent a prime venue for HIV prevention with these difficult-to-reach populations; however, little research exists on effective approaches to HIV prevention within these communities. Using a mixed-methods approach, the present study sought to document participation in HIV prevention activities of a sample from the Los Angeles House and Ball communities (N=263) in order to inform future service development. While 80% of participants were tested for HIV within the past 6 months, only 26% report HIV prevention program attendance. House leaders recommend a holistic approach to HIV prevention, one that incorporates attention to social problems beyond HIV, including poverty, housing difficulties, and lack of job training.

One group often overlooked by HIV prevention efforts is adolescent children of mothers living with HIV (MLH). Despite their potential vulnerability, very few evidence-based prevention programs exist for this population in the United States (U.S.) and elsewhere. The current study introduces a parent-based program adapted for families affected by HIV for the purpose of preventing adolescent HIV infection. Following a structured process of adaptation, 12 African American MLH-adolescent dyads were recruited from HIV clinics and non-governmental organizations in a southeastern U.S. city to participate in a feasibility pilot evaluation of the adapted program (Moms Stopping It Now! [Ms. Now]). The intervention consisted of group and individual sessions implemented in a university setting and at participants' homes, respectively. We determined feasibility through assessing participant acceptability and signs of intervention efficacy. Quantitative and qualitative process data revealed high levels of acceptability, as participants were largely satisfied and engaged with Ms. Now, and were willing to attend most sessions. In addition, positive intervention effects approaching medium to large effect sizes were observed for some protective parenting outcomes, including increases in parent-child relationship quality, parental monitoring, maternal HIV disclosure self-efficacy, and communication about maternal HIV infection. Other outcomes, namely communication about sex topics, did not show positive shifts due to ceiling effects and may be indicative of the pre-existing strengths these MLH possess. Ms. Now's approach and further refinement is discussed in the context of strengthening families affected by HIV. Moreover, we recommend that policy aimed at program development consider jointly targeting these populations (MLH and adolescents) due to the unique benefits of family intervention.

Pre-exposure prophylaxis" (PrEP) has been recently developed as a prevention strategy which involves the administration of drugs to non-infected individuals who present high exposure or susceptibility to HIV. Although this use is not approved in our country, several guidelines recommend PrEP as a prevention option in adult MSM, heterosexual men and women, and users of parenteral drugs at risk of acquiring the infection. This article presents the characteristics that an ideal agent to be used as PrEP should meet, recent efficacy published data and barriers for the implementation of this new strategy. On the other hand, the role of hospital pharmacists will be discussed.

In Uganda, a nationwide scale-up of provider-initiated HIV testing and counselling presents an opportunity to deliver HIV-prevention services to large numbers of people. In a rural Ugandan hospital, focus group discussions and key informant interviews were conducted with outpatients receiving provider-initiated HIV testing and counselling and staff to explore the HIV-prevention information, motivation and behavioural skills strengths and weaknesses, and community-level and structural barriers to provider-initiated HIV testing and counselling acceptability and HIV prevention among this population. Strengths and weakness occurred at all levels, and results suggest brief client-centred interventions during provider-initiated HIV testing and counselling may be an effective approach to increase prevention behaviours in outpatient settings.

Evidence that treating people with HIV early in infection prevents transmission to sexual partners has reframed HIV prevention paradigms. The resulting emphasis on HIV testing as part of prevention strategies has rekindled the debate as to whether laws that criminalise HIV transmission are counterproductive to the human rights-based public health response. It also raises normative questions about what constitutes 'safe(r) sex' if a person with HIV has undetectable viral load, which has significant implications for sexual practice and health promotion. This paper discusses a recent high-profile Australian case where HIV transmission or exposure has been prosecuted, and considers how the interpretation of law in these instances impacts on HIV prevention paradigms. In addition, we consider the implications of an evolving medical understanding of HIV transmission, and particularly the ability to determine infectiousness through viral load tests, for laws that relate to HIV exposure (as distinct from transmission) offences. We conclude that defensible laws must relate to appreciable risk. Given the evidence that the transmissibility of HIV is reduced to negligible level where viral load is suppressed, this needs to be recognised in the framing, implementation and enforcement of the law. In addition, normative concepts of 'safe(r) sex' need to be expanded to include sex that is 'protected' by means of the positive person being virally suppressed. In jurisdictions where use of a condom has previously mitigated the duty of the person with HIV to disclose to a partner, this might logically also apply to sex that is 'protected' by undetectable viral load.
The objectives of this study were to describe knowledge, attitudes, and self-awareness, and to identify predictable factors affecting HIV/AIDS prevention among Thai university students. A cross sectional survey was conducted among 844 first-year university students using a validated, self-administered questionnaire as a research instrument. The questionnaire included items assessing knowledge, attitudes, self-awareness, and HIV/AIDS preventive behaviors. It was found that 22.4% of the subjects received various sexually provocative media. The university student's knowledge, attitudes, self-awareness, and preventive behaviors toward HIV/AIDS were at a high level. The results from the multiple regression analysis identified self-awareness, faculty, sex, sexual-risk score, income-per-month, GPA, and knowledge as significant independent predictors of HIV/AIDS preventive behaviors. These factors contributed to 36.9% of the explanation of HIV preventive behaviors, and the strongest predictor was found to be self-awareness. Scientific information, and useful and productive life skills are needed to educate the university students regarding the health consequences of HIV/AIDS. An integrated approach is strongly suggested for creating knowledge, attitudes, and awareness to control the spread of HIV/AIDS among young people.

In March 2006, the Centers for Disease Control and Prevention (CDC) convened a consultation meeting to explore microenterprise as a potential human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) prevention intervention. The impulse to link microenterprise with HIV/AIDS prevention was driven by the fact that poverty is a significant factor contributing to the risk for infection. Because increasingly high rates of HIV infection are occurring among women, particularly among poor African American women in the southern United States, we focused the consultation on microenterprise as an intervention among that population. In the international arena, income generated by microenterprise has contributed to improving family and community health outcomes. This article summarizes the contributions made to the consultation by participants from the diverse fields of microenterprise, microfinance, women's studies, and public health. The article ends with recommendations for HIV/AIDS prevention and, by implication, addressing other public health challenges, through the development of multifaceted intervention approaches.

Young men who have sex with men (YMSM) are increasingly using mobile smartphone applications ("apps"), such as Grindr, to meet sex partners. A probability sample of 195 Grindr-using YMSM in Southern California were administered an anonymous online survey to assess patterns of and motivations for Grindr use in order to inform development and tailoring of smartphone-based HIV prevention for YMSM. The number one reason for using Grindr (29 %) was to meet "hook ups." Among those participants who used both Grindr and online dating sites, a statistically significantly greater percentage used online dating sites for "hook ups" (42 %) compared to Grindr (30 %). Seventy percent of YMSM expressed a willingness to participate in a smartphone app-based HIV prevention program. Development and testing of smartphone apps for HIV prevention delivery has the potential to engage YMSM in HIV prevention programming, which can be tailored based on use patterns and motivations for use.

Inadequate uptake of testing for human immunodeficiency virus (HIV) remains a primary bottleneck toward universal access to treatment and care, and is an obstacle to realizing the potential of new interventions for preventing HIV infection, including treatment for prevention and preexposure prophylaxis. HIV self-testing offers an approach to scaling up testing that could be high impact, low cost, confidential, and empowering for users. Although HIV self-testing was first considered >20 years ago, it has not been widely implemented. We conducted a review of policy and research on HIV self-testing, which indicates that policy is shifting toward a more flexible approach with less emphasis on pretest counseling and that HIV self-testing has been adopted in a number of settings. Empirical research on self-testing is limited, resulting in a lack of an evidence base upon which to base policy recommendations. Relevant research and investment in programs are urgently needed to enable consideration of developing formalized self-testing programs. PMID:23487385

Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome.

Mexico has a concentrated HIV epidemic, with male sex workers constituting a key affected population. We estimated annual HIV cumulative incidence among male sex workers' partners, and then compared incidence under three hypothetical intervention scenarios: improving condom use; and scaling up HIV treatment as prevention, considering current viral suppression rates (CVS, 60.7 %) or full viral suppression among those treated (FVS, 100 %). Clinical and behavioral data to inform model parameterization were derived from a sample (n = 79) of male sex workers recruited from street locations and Clínica Condesa, an HIV clinic in Mexico City. We estimated annual HIV incidence among male sex workers' partners to be 8.0 % (95 % CI: 7.3-8.7). Simulation models demonstrated that increasing condom use by 10 %, and scaling up HIV treatment initiation by 50 % (from baseline values) would decrease the male sex workers-attributable annual incidence to 5.2, 4.4 % (CVS) and 3.2 % (FVS), respectively. Scaling up the number of male sex workers on ART and implementing interventions to ensure adherence is urgently required to decrease HIV incidence among male sex workers' partners in Mexico City.

HIV testing plays a critical role in preventing the spread of the virus and identifying infected individuals in need of care. Voluntary counseling and testing centers (VCTs) not only conduct testing but they also provide counseling. Since a proportion of people who test negative for HIV on their previous visit will return for retesting, the frequency of retesting and the characteristics of those who retest may provide insights into the efficacy of testing and counseling strategies. In this cross-sectional, retrospective study of 1,482 VCT clients in Croatia in 2010, 44.3% had been tested for HIV before. The rate of repeat HIV testing is lower in Croatia than in other countries. Men who have sex with men (MSM) clients, those with three or more sexual partners in the last 12 months, consistent condom users with steady partners, and intravenous drug users were more likely to be repeat testers. This finding suggests that clients presenting for repeat HIV testing are those who self-identify as being at a higher risk of infection. Our data showed that testing positive for HIV was not associated with repeat testing. However, the effects of repeat testing on HIV epidemiology needs to be explored. PMID:24705595

Abstinence-until-marriage (AUM) – strongly supported by religious conservatives in the U.S. - became a key element of initial HIV prevention efforts under the President’s Emergency Plan for AIDS Relief (PEPFAR). AUM programs have demonstrated limited efficacy in changing behaviors, promoted medically inaccurate information, and withheld life-saving information about risk reduction. A focus on AUM also undermined national efforts in Africa to create integrated youth HIV prevention programs. PEPFAR prevention efforts after 2008 shifted to science-based programming, however vestiges of AUM remain. Primary prevention programs within PEPFAR are essential and nations must be able to design HIV prevention based on local needs and prevention science. PMID:23327516

The biomedical intervention that has had a major impact on the natural history of HIV and on the global HIV epidemic is antiretroviral therapy (ART). However, the emergence of drug-resistant HIV, an inevitable consequence of increasing use of antiretroviral drugs, poses a major threat to ART success. At the turn of this century, access to life-saving ART was accelerated in low and middle-income countries with the Millennium Development Goal of 15 million individuals receiving ART by 2015 expected to be achieved. However, ART access needs to continue to expand to help bring HIV under control by 2030. The standard of care for people living with HIV in resource- limited settings differs dramatically compared to high-income countries, and not unexpectedly, ART rollout in these settings has resulted in an increase in acquired and transmitted drug resistance. Also of concern, the same drug classes used for ART have been approved or are being progressed for HIV prevention and drug resistance could mitigate their effectiveness for treatment and prevention. In the absence of an effective HIV vaccine and cure, it is imperative that the antiretroviral drug pipeline contains new classes of HIV inhibitors that are active against circulating drug-resistant strains. Studies to advance our fundamental understanding of HIV replication needs to continue, including the interplay between virus and host cell factors, to identify and characterize new drug targets for chemotherapeutic intervention.

Background HIV-1 has proved to infect regulatory T cells (Treg) modifying their phenotype and impairing their suppressive capacity. As Treg cells are a crucial component in the preservation of the immune homeostasis, we researched that the antiviral capacity of carboxilan dendrimers prevents the HIV-1 infection of Treg and their effects. The phenotype and suppressive capacity of Treg treated or non-treated with carbosilane dendrimers were studied by flow cytometry. Treated and non-treated Treg from healthy donors were infected with HIV-1NL4.3. The infection of Treg cells by HIV-1, and protective effect of two dendrimers were determined by measuring antigen p24gag in the supernatant of the culture and intracellular. Results The Treg cells were treated with cationic and anionic carbosilane dendrimers. The results showed that both dendrimers did not modify the phenotype and functionality of Treg cells compared with non- treated Treg cells. Anionic dendrimers showed high biocompatibility with normal activity of the Treg cells and in antiviral assays. These dendrimers were highly active against HIV-1 preventing the infection of Treg, and were able to protect the Treg from the Foxp3 downregulation induced by the HIV-1 infection. Conclusions This is the first work showing that the in vitro use of anionic dendrimers prevent the HIV-1 replication and the infection of expanded Treg cells in culture, which raises the possibility to use Treg cells therapeutically in HIV-1-infected subjects.

Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed.

Dendrimers containing from 9 to 18 tryptophan residues at the peryphery have been efficiently synthesized and tested against HIV replication. These compounds inhibit an early step of the replicative cycle of HIV, presumably virus entry into its target cell. Our data suggest that HIV inhibition can be achieved by the preferred interaction of the compounds herein described with glycoproteins gp120 and gp41 of the HIV envelope preventing interaction between HIV and the (co)receptors present on the host cells. The results obtained so far indicate that 9 tryptophan residues on the periphery are sufficient for efficient gp120/gp41 binding and anti-HIV activity.

Because of the enormity of the HIV-AIDS epidemic and the urgency for preventing transmission, HIV prevention programs are a high priority for careful and timely evaluations. Information on program effectiveness and efficiency is needed for decision-making about future HIV prevention priorities. General characteristics of successful HIV prevention programs, programs empirically evaluated and found to change (or not change) high-risk behaviors or in need of further empirical study, and economic evaluations of certain programs are described and summarized with attention limited to programs that have a behavioral basis. HIV prevention programs have an impact on averting or reducing risk behaviors, particularly when they are delivered with sufficient resources, intensity, and cultural competency and are based on a firm foundation of behavioral and social science theory and past research. Economic evaluations have found that some of these behaviorally based programs yield net economic benefits to society, and others are likely cost-effective (even if not cost-saving) relative to other health programs. Still, specific improvements should be made in certain HIV prevention programs. PMID:7630989

One quarter of HIV cases occur in women ages 15-44 years. We investigated preferential HIV prevention message mediums among college women (18-21 years of age) and their association with parent and partner communication. A nonexperimental cross-sectional survey assessed factors associated with parent and partner communication among 626 single female students who were sexually active in the previous 6 months and attending a 4-year public university in Florida. Women who perceived themselves to be at elevated risk of acquiring HIV were more likely to communicate with their parents (p < .05), but not their partners. In multivariable analysis, students were more likely to communicate about sexual risk behavior with their parents when mothers were younger and when less influenced by their peers. Reading items on the Internet about intravenous drug use and HIV were independently associated with higher parent and partner communication, respectively. Findings can guide future HIV prevention communication interventions.

This discursive article introduces HIV treatment as prevention (TasP) and identifies various models for its extrapolation to wider population levels. Drawing on HIV surveillance data for Jamaica and Barbados, the article identifies significant gaps in HIV response programming in relation to testing, antiretroviral treatment coverage, and treatment adherence, thereby highlighting the disparity between assumptions and prerequisites for TasP success. These gaps are attributable, in large part, to sociocultural impediments and structural barriers, severe resource constraints, declining political will, and the redefinition of HIV as a manageable, chronic health issue. Antiretroviral treatment and TasP can realize success only within a combination prevention frame that addresses structural factors, including stigma and discrimination, gender inequality and gender-based violence, social inequality, and poverty. The remedicalization of the response compromises outcomes and undermines the continued potential of HIV programming as an entry point for the promotion of sexual, health, and human rights.

The global diversity of HIV epidemics can be explained in part by types and patterns of sexual partnerships. We offer a typology of sexual partnerships that corresponds to varying levels of HIV-transmission risk to help guide thinking about appropriate behavioral interventions, particularly in the epidemics of sub-Saharan Africa. Declines in HIV prevalence have been associated with reductions in numbers of sex partners, whereas many other prevention strategies have not been demonstrated to reduce HIV transmission at a population level. We suggest a reorientation of current prevention efforts, based on the epidemiology of sexually transmitted HIV epidemics and trends in sexual behavior change. Concurrent sexual partnerships are likely to play a large role in transmission dynamics in the generalized epidemics of East and Southern Africa, and should be addressed through improved behavior-change interventions.

To address the persistent HIV epidemic in the United States, prevention efforts are focusing on social determinants related to HIV risk by targeting systems and structures, such as organizational and institutional policies, practices and programs, and legislative and regulatory approaches to modify features of the environment that influence HIV risk. With limited evidenced-based examples, communities can benefit from strategic planning resources that help them consider developing structural-level changes that target root causes of HIV risk. In this article, we present the Connect to Protect® project that outlines a process and a tool to move from general ideas to specific structural changes. Examples from 14 coalitions are also provided. Using the process and tools presented here can provide a launching pad for other coalitions seeking to build an HIV prevention agenda and for practitioners seeking to incorporate structural changes for community health promotion.

Researchers increasingly argue that poverty and gender inequality exacerbate the spread of HIV/AIDS and that economic empowerment can therefore assist in the prevention and mitigation of the disease, particularly for women. This paper critically evaluates such claims. First, we examine the promises and limits of integrated HIV/AIDS prevention and microfinance programs by examining the available evidence base. We then propose future research agendas and next steps that may help to clear current ambiguities about the potential for economic programs to contribute to HIV/AIDS risk reduction efforts.

The population within the criminal justice system suffers from various health disparities including HIV and hepatitis C virus (HCV). African American and Latino offenders represent the majority of the offender population. Evidence-based interventions to prevent HIV and HCV among criminal justice clients are scant and usually do not take cultural differences into account. Toward this end, this study describes the process of culturally adapting an HIV/HCV prevention intervention for Latino criminal justice clients in Miami, Florida, by using the ecological validity model. Recommendations for culturally adapting an intervention for Latinos include an emphasis on language and integrating cultural themes such as familism and machismo.

Abstract Thirty-day readmission rates, a widely utilized quality metric, are high among HIV-infected individuals. However, it is unknown how many 30-day readmissions are preventable, especially in HIV patients, who have been excluded from prior potentially preventable readmission analyses. We used electronic medical records to identify all readmissions within 30 days of discharge among HIV patients hospitalized at a large urban safety net hospital in 2011. Two independent reviewers assessed whether readmissions were potentially preventable using both published criteria and detailed chart review, how readmissions might have been prevented, and the phase of care deemed suboptimal (inpatient care, discharge planning, post-discharge). Of 1137 index admissions, 213 (19%) resulted in 30-day readmissions. These admissions occurred among 930 unique HIV patients, with 130 individuals (14%) experiencing 30-day readmissions. Of these 130, about half were determined to be potentially preventable using published criteria (53%) or implicit chart review (48%). Not taking antiretroviral therapy (ART) greatly increased the odds of a preventable readmission (OR 5.9, CI:2.4–14.8). Most of the preventable causes of readmission were attributed to suboptimal care during the index hospitalization. Half of 30-day readmission in HIV patients are potentially preventable. Increased focus on early ART initiation, adherence counseling, management of chronic conditions, and appropriate timing of discharge may help reduce readmissions in this vulnerable population.

Abstract New HIV infections among younger men who have sex with men (MSM) in the United States are escalating. Data on HIV infections in college students are limited. In 2010, three MSM college students presented to our clinic with primary HIV infection (PHI) in a single month. To determine the number of college students among new HIV diagnoses, we reviewed clinical characteristics and molecular epidemiology of HIV-diagnosed individuals from January to December 2010 at the largest HIV clinic in Southern New England. PHI was defined as acute HIV infection or seroconversion within the last 6 months. Of 66 individuals diagnosed with HIV in 2010, 62% were MSM and 17% were academic students (12% college or university, 5% other). Seventy-three percent of students were MSM. Compared to nonstudents, students were more likely to be younger (24 versus 39 years), born in the United States (91% versus 56%), have another sexually transmitted disease (45% versus 11%), and present with PHI (73% versus 16%, all p-values<0.05). Thirty percent of individuals formed eight transmission clusters including four students. MSM were more likely to be part of clusters. Department of Health contact tracing of cluster participants allowed further identification of epidemiological linkages. Given these high rates of PHI in recently diagnosed students, institutions of higher education should be aware of acute HIV presentation and the need for rapid diagnosis. Prevention strategies should focus on younger MSM, specifically college-age students who may be at increased risk of HIV infection. PMID:22724920

Despite the fact that older women represent a growing risk group for HIV, they have been rarely targeted by public health campaigns designed to prevent HIV/AIDS and are often excluded from many prevention studies. This unique cohort may be often overlooked due to beliefs that older women are not sexually active and do not engage in high risk sexual activity. Data suggest a need for increased attention to this unique cohort. Risk reduction interventions tailored to the special needs of people living with HIV/AIDS have begun to demonstrate promising results. In this manuscript, we report the 6 month outcomes for female participants in Project ROADMAP, a secondary prevention intervention designed to reduce high risk sexual behavior in older adults living with HIV/AIDS. Our results indicate that female participants in the intervention group were more likely to report a reduction in high risk sexual behavior than women in the control condition. Our findings also suggest that the intervention succeeded in increasing the HIV-related knowledge of the participants and decreasing their stigma vis-à-vis the HIV condition. The study findings suggest that Project ROADMAP is an effective secondary prevention intervention for sexually active older HIV positive women.

Although reducing HIV risk is a primary motive for the design of HIV prevention interventions, the goals of the clients may be very different. Social theories of gender suggest that women, who often seek to resolve social and relational problems, may see HIV-prevention counseling as a mean of resolving partner violence. In contrast, men, who often worry about their physical strength, may seek to enroll in HIV-prevention programs when they experience physical symptoms unrelated to HIV. An unobtrusive study was conducted to observe enrollment in HIV risk-reduction counseling after measuring partner-violence complaints (e.g., feeling threatened or being hit), emotional complaints (e.g., fatigue or anxiety), and physical complaints (e.g., cardiovascular or digestive symptoms). The sample was a group of 350 participants, 70% clients from a state-health department in North Central Florida and 30% community members. Consistent with predictions, complaints of partner violence had a positive association with enrollment in women but not in men, whereas complaints about physical health had a positive association with enrollment in men, but not in women. Emotional complaints did not predict enrollment in either gender group. This study suggests that broad, gender-specific population needs must be competently addressed within HIV-prevention programs and may be strategically used to increase program enrollment.

In fiscal year (FY) 2012, the Centers for Disease Control and Prevention (CDC) reallocated their HIV prevention funding to U.S. states, territories, and some cities so as to be more highly correlated with 2008 HIV prevalence. A jurisdiction's HIV prevention funding could drop as low as $750,000 for FY 2016. Iowa was one state that experienced a substantial funding drop, and it chose to undertake a mathematical modeling exercise to inform the following questions: (a) Given current HIV prevention funding for the state, what is the optimal allocation of resources to maximize infections averted? (b) With this "optimal" resource allocation, how many (and what percentage of) HIV infections in the state can be averted? (c) Is the optimal resource allocation sufficient to achieve the National HIV/AIDS Strategy goal of 25% reduction in HIV incidence? and (d) With the "optimal" resource allocation, is the return on the investment such that it might be considered cost-effective? Here, we describe the results of the policy analysis, and the uses of the results.

Purpose The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. Design This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI’s preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. Findings After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. Conclusions The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. Clinical Relevance The study provided important information about the ability of an Internet-based intervention to reduce young women’s risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. PMID:25410132

We developed an interactive, customizable, Web-based program focused on the prevention of HIV, sexually transmitted infections, and hepatitis among youth. Results from a randomized, controlled trial with youth in treatment for substance use demonstrated that this Web-based tool, when provided as an adjunct to an educator-delivered prevention intervention, increased accurate prevention knowledge, increased intentions to carefully choose partners, and was perceived as significantly more useful relative to the educator-delivered intervention when provided alone. Results suggest this Web-based program may be effective and engaging and may increase the adoption of effective HIV and disease prevention science for youth. Limitations are discussed.

The Division of HIV/AIDS Prevention (DHAP) at the Centers for Disease Control and Prevention has an annual budget of approximately $325 million for funding HIV prevention programs in the U.S. The purpose of this paper is to thoroughly describe the methods used to develop a national HIV resource allocation model intended to inform DHAP on allocation strategies that might improve the overall effectiveness of HIV prevention efforts. The HIV prevention resource allocation problem consists of choosing how to apportion prevention resources among interventions and populations so that HIV incidence is minimized, given a budget constraint. We developed an epidemic model that projects HIV infections over time given a specific allocation scenario. The epidemic model is then embedded in a nonlinear mathematical optimization program to determine the allocation scenario that minimizes HIV incidence over a 5-year horizon. In our model, we consider the general U.S. population and specific at-risk populations. The at-risk populations include 15 subgroups structured by gender, race/ethnicity and HIV transmission risk group. HIV transmission risk groups include high-risk heterosexuals, men who have sex with men and injection drug users. We consider HIV screening interventions and interventions to reduce HIV-related risk behaviors. The output of the model is the optimal funding scenario indicating the amounts to be allocated to all combinations of populations and interventions. For illustrative purposes only, we provide a sample application of the model. In this example, the optimal allocation scenario is compared to the current baseline funding scenario to highlight how the current allocation of funds could be improved. In the baseline allocation, 29% of the annual budget is aimed at the general population, while the model recommends targeting 100% of the budget to the at-risk populations with no allocation targeted to the general population. Within the allocation to behavioral

Men who have sex with men (MSM) in the Americas require targeted, combination HIV prevention approaches. We solicited client and provider perspectives on emerging prevention interventions including HIV pre-exposure prophylaxis (PrEP) and HIV self-tests through focus groups and in-depth interviews with 130 MSM and 41 providers across four sites: New York, San Francisco, Lima, and Rio de Janeiro. Among the MSM participants, we identified three prevention typologies: non-condom users, inconsistent condom users, and consistent condom users. Northern and Southern MSM differed in the variety of harm reduction strategies utilized: where U.S. MSM relied on condom use as well as disclosure and seroadaptive behaviors for prevention, condom use without disclosure or serostatus discussions was the norm in South America. Interest in new prevention technologies was shaped by the social context. U.S. MSM preferences differed by typology, such that non-condom users were interested in taking PrEP and using home HIV tests. MSM in Brazil, regardless of typology, were interested in exploring new prevention options. MSM in Peru demonstrated moderate interest but were less comfortable with adopting new strategies. MSM and providers’ opinions differed substantially with respect to new prevention options. Across sites, most providers were reticent to engage with new prevention options, though some NGO-based providers were more supportive of exploring new prevention tools. Both clients and providers will need to be engaged in developing integrated prevention strategies for MSM. PMID:25826246

Adolescents in therapeutic schools are at greater risk for HIV and other STIs than their peers due to earlier higher rates of sexual risk and difficulty managing strong emotions. HIV prevention programs that incorporate techniques for affect management during sexual situations may be beneficial. This paper determined the immediate impact of such an intervention, Affect Management (AM), compared to a standard, skills-based HIV prevention intervention (SB) and a general health promotion intervention (HP) for 377 youth, ages 13 to 19, in therapeutic schools in two cities. One month after the intervention, analyses that adjusted for the baseline scores found adolescents in AM were more likely to report condom use at last sex than those in HP (.89 vs. .67, p=.02) and that their HIV knowledge was significantly greater. These data suggest that affect management techniques might improve the impact of standard skills-based prevention programs for adolescents in therapeutic schools. PMID:23975475

Human Immunodeficiency Virus (HIV) leading to the diseased state Acquired Immunodeficiency syndrome (AIDS) and other Sexually Transmitted Diseases caused by various microorganisms are posing a major threat to humankind. Hence there is an urgent need for controlling its spread. In 2008, about 30 million people are living with HIV infection in the world. Heterosexual transmission particularly affecting woman is driving the epidemic today in many resource poor countries, where most of the infections are occurring. One of the biggest potential for prevention for HIV today lies in a method of using a topical microbicide. Microbicides are applied to vaginal or rectal microbicide surfaces with the goal of preventing or at least significantly reducing the transmission of sexually transmitted infections (STI's). This article is presented here as an overview of the various HIV transmission and prevention methods, microbicide development pipeline and other important aspects concerned with it.

Adult male circumcision has been shown to reduce the transmission of HIV. Women's acceptability of male circumcision is important in Papua New Guinea's preparedness to introduce male circumcision, and in ethical considerations of its use as a biomedical technology for HIV prevention. We conducted 21 focus group discussions and 18 in-depth interviews with women in all four regions of Papua New Guinea. The majority of women objected to the introduction of male circumcision for three main reasons: circumcision would result in sexual risk compensation; circumcision goes against Christian faith; and circumcision is a new practice that is culturally inappropriate. A minority of women accepted male circumcision for the prevention of HIV and other sexually transmitted infections, and for the benefit of penile hygiene and health. Women's objections to circumcision as a biomedical method of preventing HIV reemphasize the importance of sociocultural and behavioral interventions in Papua New Guinea.

Social marketing techniques have been tested and proven useful within the health sector worldwide. In Fiji, social marketing was introduced in the early 1990s, and more rapidly during the last decade to improve national response to an increasing incidence of sexually transmitted infections (STIs) such as human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). Given the limited amount of research in the area of program evaluation in Pacific Island Countries and Territories (PICTs), this study systematically analyzes five Fijian HIV/AIDS prevention programs through Andreasen's benchmark criteria, in order to identify gaps in program design that ultimately impact program effectiveness. Assessment results unveil some interesting trends regarding the focus and applications of past Fijian HIV/AIDS prevention programs in the past decade. This article discusses these findings and other valuable lessons for future HIV/AIDS prevention strategies in Fiji and elsewhere.

To determine if a structural intervention of providing one condom a week to inmates in the Los Angeles County Men's Central Jail MSM unit reduces HIV transmissions and net social cost, we estimated numbers of new HIV infections (1) when condoms are available; and (2) when they are not. Input data came from a 2007 survey of inmates, the literature and intervention program records. Base case estimates showed that condom distribution averted 1/4 of HIV transmissions. We predict .8 new infections monthly among 69 HIV-negative, sexually active inmates without condom distribution, but .6 new infections with condom availability. The discounted future medical costs averted due to fewer HIV transmissions exceed program costs, so condom distribution in jail reduces total costs. Cost savings were sensitive to the proportion of anal sex acts protected by condoms, thus allowing inmates more than one condom per week could potentially increase the program's effectiveness.

Since the beginning of the epidemic, the protection of human rights has been an integral component in the response to Human Immunodeficiency Virus (HIV). The high degree of stigma and discrimination associated with acquired immune deficiency syndrome (AIDS) has made human rights protection not only a priority to ensure the rights of people living with and at-risk for HIV, but to address public health goals as well. Advances in understanding the impact of antiretroviral treatment on HIV prevention provide exciting opportunities and even a paradigm shift in terms of AIDS prevention. However, this potential cannot be reached unless the advancement of human rights is a primary component of treatment and prevention programme and policy development. The use of antiretroviral treatment as prevention reinforces the value of basic principles related to the dignity and agency of people living with HIV to participate in the design and implementation of programmes, to be informed and to make informed decisions about their health and lives, to be protected from harm, and to have opportunities to seek redress and accountability for abuses. The possibility of using HIV treatment as a prevention tool means that now, more than ever, legal reform and community empowerment and mobilisation are necessary to realize the rights and health of people affected by HIV.

Expanding essential health services through non-government organisations (NGOs) is a central strategy for achieving universal health coverage in many low-income and middle-income countries. Human immunodeficiency virus (HIV) prevention services for key populations are commonly delivered through NGOs and have been demonstrated to be cost-effective and of substantial global public health importance. However, funding for HIV prevention remains scarce, and there are growing calls internationally to improve the efficiency of HIV prevention programmes as a key strategy to reach global HIV targets. To date, there is limited evidence on the determinants of costs of HIV prevention delivered through NGOs; and thus, policymakers have little guidance in how best to design programmes that are both effective and efficient. We collected economic costs from the Indian Avahan initiative, the largest HIV prevention project conducted globally, during the first 4 years of its implementation. We use a fixed-effect panel estimator and a random-intercept model to investigate the determinants of average cost. We find that programme design choices such as NGO scale, the extent of community involvement, the way in which support is offered to NGOs and how clinical services are organised substantially impact average cost in a grant-based payment setting.

Apart from individual alcohol drinking behavior, the context or places where people drink play a significant role in HIV transmission risk. In this paper, we review the research that has been conducted on alcohol venues to identify the social and structural factors (e.g., social norms, sexual behavior) that are associated with HIV risk in these places, to review HIV prevention interventions based in alcohol venues, and to discuss appropriate methodologies for alcohol venue research. Alcohol venues are defined here as places that sell or serve alcohol for onsite consumption, including bars, bottle stores, nightclubs, wine shops, and informal shebeens. Despite the many established HIV risk factors at play in alcohol venues, limited prevention strategies have been implemented in such places. A total of 11 HIV prevention interventions or programs were identified. HIV prevention interventions in alcohol venues may be conducted at the individual, social, or structural level. However, multilevel interventions that target more than one level appear to lead to the most sustainable behavior change. Strategies to incorporate alcohol venues in biomedical prevention strategies including antiretroviral therapy for alcohol users are also discussed. PMID:26099244

Abstract Expanding essential health services through non‐government organisations (NGOs) is a central strategy for achieving universal health coverage in many low‐income and middle‐income countries. Human immunodeficiency virus (HIV) prevention services for key populations are commonly delivered through NGOs and have been demonstrated to be cost‐effective and of substantial global public health importance. However, funding for HIV prevention remains scarce, and there are growing calls internationally to improve the efficiency of HIV prevention programmes as a key strategy to reach global HIV targets. To date, there is limited evidence on the determinants of costs of HIV prevention delivered through NGOs; and thus, policymakers have little guidance in how best to design programmes that are both effective and efficient. We collected economic costs from the Indian Avahan initiative, the largest HIV prevention project conducted globally, during the first 4 years of its implementation. We use a fixed‐effect panel estimator and a random‐intercept model to investigate the determinants of average cost.

Given current constraints on universal treatment campaigns, recent advances in public health prevention initiatives have revitalized efforts to stem the tide of HIV transmission. Yet, despite a growing imperative for prevention—supported by the promise of behavioral, structural and biomedical approaches to lower the incidence of HIV—human rights frameworks remain limited in addressing collective prevention policy through global health governance. Assessing the evolution of rights-based approaches to global HIV/AIDS policy, this review finds that human rights have shifted from collective public health to individual treatment access. While the advent of the HIV/AIDS pandemic gave meaning to rights in framing global health policy, the application of rights in treatment access litigation came at the expense of public health prevention efforts. Where the human rights framework remains limited to individual rights enforced against a state duty bearer, such rights have faced constrained application in framing population-level policy to realize the public good of HIV prevention. Concluding that human rights frameworks must be developed to reflect the complementarity of individual treatment and collective prevention, this article conceptualizes collective rights to public health, structuring collective combination prevention to alleviate limitations on individual rights frameworks and frame rights-based global HIV/AIDS policy to assure research expansion, prevention access and health system integration.

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

China's commitment to implementing established and emerging HIV/AIDS prevention and control strategies has led to substantial gains in terms of access to antiretroviral treatment and prevention services, but the evolving and multifaceted HIV/AIDS epidemic in China highlights the challenges of maintaining that response. This study presents modeling results exploring the potential impact of HIV vaccines in the Chinese context at varying efficacy and coverage rates, while further exploring the potential implications of vaccination programs aimed at reaching populations at highest risk of HIV infection. A preventive HIV vaccine would add a powerful tool to China's response, even if not 100% efficacious or available to the full population.

Introduction Studies in heterosexual HIV serodiscordant couples have provided critical evidence on the role of HIV treatments in reducing HIV transmission risk. However, there are limited data regarding the effect of treatment on HIV transmission in homosexual male couples. We examined features of male homosexual HIV serodiscordant relationships that may impact upon the design of HIV treatment and transmission studies. Methods Data were from a prospective cohort study of HIV-negative homosexual men in Sydney, Australia. Men were followed up with six-monthly interviews and annual testing for HIV. Characteristics of men in HIV serodiscordant and seroconcordant relationships at baseline were compared, and a longitudinal analysis performed of rate of relationship break-up and of HIV incidence. Results At baseline, 5.5% of participants (n=79) had an HIV-positive partner. Most (80.8%) of these relationships were non-monogamous, and 36.7% of men reported recent unprotected anal intercourse (UAI) with casual partners. The rate of relationship break-up was 29.5 per 100 person-years. Half of men in serodiscordant relationships (49.4%) reported recent UAI with their regular partners. HIV incidence was 2.2 per 100 person-years. It was substantially higher in relationships of less than one year's duration (6.1 per 100 person-years) and in men who reported unprotected receptive anal intercourse with ejaculation with their regular partners (15.5 per 100 person-years). Conclusions Levels of HIV transmission risk and incidence were high, particularly in early relationships. Rates of relationship break-up were high. These data suggest that studies of HIV treatments and transmission in homosexual serodiscordant couples should focus on early relationships so as not to underestimate risk, and sample sizes must allow for high rates of relationship break-up.

In the HPTN 052 study, transmission between HIV-discordant couples was reduced by 96% when the HIV-infected partner received suppressive antiretroviral therapy (ART). We examined two transmission events where the newly infected partner was diagnosed after the HIV-infected partner (index) initiated therapy. We evaluated the sequence complexity of the viral populations and antibody reactivity in the newly infected partner to estimate the dates of transmission to the newly infected partners. In both cases, transmission most likely occurred significantly before HIV-1 diagnosis of the newly infected partner, and either just before the initiation of therapy or before viral replication was adequately suppressed by therapy of the index. This study further strengthens the conclusion about the efficacy of blocking transmission by treating the infected partner of discordant couples. However, this study does not rule out the potential for HIV-1 transmission to occur shortly after initiation of ART, and this should be recognized when antiretroviral therapy is used for HIV-1 prevention.

The Joint United Nations Programme on HIV/AIDS (UNAIDS) recently updated its global targets for antiretroviral therapy (ART) coverage for HIV-positive persons under which 90 % of HIV-positive people are tested, 90 % of those are on ART, and 90 % of those achieve viral suppression. Treatment policy is moving toward treating all HIV-infected persons regardless of CD4 cell count-otherwise known as treatment as prevention-in order to realize the full therapeutic and preventive benefits of ART. Mathematical models have played an important role in guiding the development of these policies by projecting long-term health impacts and cost-effectiveness. To guide future policy, new mathematical models must consider the barriers patients face in receiving and taking ART. Here, we describe the HIV care cascade and ART delivery supply chain to examine how mathematical modeling can provide insight into cost-effective strategies for scaling-up ART coverage in sub-Saharan Africa and help achieve universal ART coverage.

Harm reduction-based HIV prevention has been in place among female sex workers (FSWs) in Croatia for more than a decade. However, little is known about how well the existing programs meet the needs of FSWs in an environment where sex work remains criminalized and highly stigmatized. This study aims to assess changes in FSWs' vulnerability to HIV infection in the 2008-2014 period. Using convenience samples of FSWs in Croatia's two largest urban settings, behavioral data were collected in 2007-2008 and 2014. Outreach workers interviewed 154 FSWs in the first wave of the survey and 158 in the second. The period under observation was characterized by a stable prevalence of most HIV-relevant risk behaviors and experiences. Significant changes in client-based victimization and HIV knowledge were observed only among FSWs in the capital city. Substantial and mostly sustained levels of sexual and nonsexual victimization call for more research into the limits of the current behavior-based harm reduction approach to HIV prevention in the country.

Based on analysis of data collected from the national tuberculosis prevention program in Djibouti between 1990 and 1996, the authors analyzed the relationship between HIV infection and tuberculosis. The study cohort comprised a total of 22,000 patients including 14,000 with documented HIV infection. Although HIV infection probably worsened the situation, it was neither the only nor the main factor involved in the resurgence of tuberculosis. Demographic growth, higher population density, and increasing poverty as well as the quality of the national tuberculosis prevention program must be taken into account. The incidence of smear-negative tuberculosis was not significantly higher in HIV-infected patients (incidence of smear positive cases, > 92%). Extrapulmonary tuberculosis especially of pleural involvement was more common (15% versus 9.4%). Treatment was effective in HIV-infected patients. If directly observed (DOT) therapy was used, there was no risk of emergence of multidrug-resistant tuberculosis strains. Drug side-effects associated with the protocols used in Djibouti were not greater in HIV-infected patients. Most additional mortality observed in HIV-infected tuberculosis patients (10.5% versus 2%) was due to progression of HIV infection.

Abstract Background: The challenge of identifying and recruiting U.S. women at elevated risk for HIV acquisition impedes prevention studies and services. HIV Prevention Trials Network (HPTN) 064 was a U.S. multisite, longitudinal cohort study designed to estimate HIV incidence among women living in communities with prevalent HIV and poverty. Venue-based sampling (VBS) methodologies and participant and venue characteristics are described. Methods: Eligible women were recruited from 10 U.S. communities with prevalent HIV and poverty using VBS. Participant eligibility criteria included age 18–44 years, residing in a designated census tract/zip code, and self-report of at least one high-risk personal and/or male sexual partner characteristic associated with HIV acquisition (e.g., incarceration history). Ethnography was conducted to finalize recruitment areas and venues. Results: Eight thousand twenty-nine women were screened and 2,099 women were enrolled (88% black, median age 29 years) over 14 months. The majority of participants were recruited from outdoor venues (58%), retail spaces (18%), and social service organizations (13%). The proportion of women recruited per venue category varied by site. Most participants (73%) had both individual and partner characteristics that qualified them for the study; 14% were eligible based on partner risk only. Conclusion: VBS is a feasible and effective approach to rapidly recruit a population of women at enhanced risk for HIV in the United States. Such a recruitment approach is needed in order to engage women most at risk and requires strong community engagement. PMID:24742266

Past research suggests that as many as 50% of onward human immunodeficiency virus (HIV) transmissions occur during acute and recent HIV infection. It is clearly important to develop interventions which focus on this highly infectious stage of HIV infection to prevent further transmission in the risk networks of acutely and recently infected individuals. Project Protect tries to find recently and acutely infected individuals and prevents HIV transmission in their risk networks. Participants are recruited by community health outreach workers at community-based HIV testing sites and drug users' community venues, by coupon referrals and through referrals from AIDS clinics. When a network with acute/recent infection is identified, network members are interviewed about their risky behaviors, network information is collected, and blood is drawn for HIV testing. Participants are also educated and given prevention materials (condoms, syringes, educational materials); HIV-infected participants are referred to AIDS clinics and are assisted with access to care. Community alerts about elevated risk of HIV transmission are distributed within the risk networks of recently infected. Overall, 342 people were recruited to the project and screened for acute/recent HIV infection. Only six index cases of recent infection (2.3% of all people screened) were found through primary screening at voluntary counseling and testing (VCT) sites, but six cases of recent infection were found through contact tracing of these recently infected participants (7% of network members who came to the interview). Combining screening at VCT sites and contact tracing the number of recently infected people we located as compared to VCT screening alone. No adverse events were encountered. These first results provide evidence for the theory behind the intervention, i.e., in the risk networks of recently infected people there are other people with recent HIV infection and they can be successfully located without

IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

This study characterized the HIV epidemic among men who have sex with men (MSM) in Quito, Ecuador and contrasted risk patterns with other STI's. 416 MSM ages 15 years and older were recruited using respondent-driven sampling in 2010-2011. Biological testing and a self-interview survey assessed HIV and STI infections and risk behaviors. Analysis incorporated recruiter-level variables and clustering adjustments to control for recruitment patterns. We identify high levels of HIV (11 %), HSV-2 (14 %) and active syphilis (5.5 %) infections, low levels of lifetime HIV testing (57 %), limited knowledge of HIV and STI's (<48 %) and limited consistent condom use independent of partner type (<40 %). Sex work was associated with all infections while associations with residential location, how casual partners are met and other variables, varied. Scale-up of behavioral prevention and HIV testing is urgently needed. Interventions should target male sex workers and exploit differential patterns of HIV-STI risk to stay ahead of the epidemic.

This article reviews current issues and advancements in social network approaches to HIV prevention and care. Social network analysis can provide a method to understand health disparities in HIV rates and treatment access and outcomes. Social network analysis is a value tool to link social structural factors to individual behaviors. Social networks provide an avenue for low cost and sustainable HIV prevention interventions that can be adapted and translated into diverse populations. Social networks can be utilized as a viable approach to recruitment for HIV testing and counseling, HIV prevention interventions, and optimizing HIV medical care and medication adherence. Social network interventions may be face-to-face or through social media. Key issues in designing social network interventions are contamination due to social diffusion, network stability, density, and the choice and training of network members. There are also ethical issues involved in the development and implementation of social network interventions. Social network analyses can also be used to understand HIV transmission dynamics.

Provision of comprehensive sexual and reproductive health (SRH) services that meet the complex and diverse needs of women, in particular, within resource-constrained settings, is often exacerbated by separate and uncoordinated reproductive health (RH) and HIV policies and programmes. A Rapid Assessment Tool for Sexual and Reproductive Health and HIV Linkages was developed to assess bi-directional linkages between SRH and HIV at policy, systems and service delivery levels, as well as to identify gaps and contribute to the development of country-specific action plans. Findings from the implementation of this Assessment Tool are of particular relevance to the successful delivery and uptake of multipurpose prevention technologies (MPTs), which are products in the development pipeline addressing multiple SRH needs of women, including HIV. The findings highlight the need for better coordination between SRH and HIV programmes in countries; support and training for healthcare providers on SRH, HIV and human rights; supporting SRH and HIV integration at the service delivery level through relevant policies, strategic and operational plans; and strengthening logistics and supplies systems to provide a combination approach to prevention. These lessons learnt could help programme managers and service providers to better understand the strategies for positioning multipurpose prevention products in national policy and service contexts.

Purpose Placebo and randomization are important concepts that must be understood before youth can safely participate in HIV vaccine studies or other biomedical trials for HIV prevention. These concepts are central to the phenomenon of preventive misconception which may be associated with an increase in risk behavior among study participants related to mistaken beliefs. Persuasive messaging, traditionally used in the field of marketing, could enhance educational efforts associated with randomized clinical trials. Methods Two educational brochures were designed to increase knowledge about HIV vaccine clinical trials via 1 and 2-sided persuasive messaging. Through the Adolescent Medicine Trials Network, 120 youth were enrolled, administered a mock HIV vaccine trial consent, and then randomized to receive either no supplemental information or one of the two brochures. Results The 2-sided brochure group in which common clinical trial misconceptions were acknowledgedand then refuted had significantly higher scores on knowledge of randomization and interpretation of side effects than the consent-only control group, and willingness to participate in an HIV vaccine trial was not decreased with the use of this brochure. Conclusion Two sided persuasive messaging improves understanding of the concepts of randomization and placebo among youth who would consider participating in an HIV vaccine trial. Further evaluation of this approach should be considered for at-risk youth participating in an actual trial of a biomedical intervention for HIV prevention. PMID:24613097
The effectiveness of antiretroviral regimes (ARVs) to reduce risk of HIV transmission from mother to child and as post-exposure prophylaxis has been known for almost two decades. Recent research indicates ARVs can also reduce the risk of HIV transmission via sexual intercourse in two other ways. With pre-exposure prophylaxis (PrEP), ARVs are used to reduce risk of HIV acquisition among persons who are HIV negative and significantly exposed to the virus. With treatment as prevention (TasP), ARVs are used to reduce risk of HIV transmission from persons who are already HIV positive. The development of these new prevention strategies raises a rationing problem: given the chronic shortage of ARVs for HIV-infected persons in need of treatment, is it ethically justified to allocate ARVs for PrEP and/or TasP? This article examines the intuitively appealing view that allocation of ARVs for treatment should be the highest priority, the use of ARVs for TasP should be a secondary priority, and that utilizing ARVs for PrEP would be unethical. I will argue that selective, evidence-based allocation of ARVs for prevention in certain cases could be ethically justified even when there is insufficient anti-retroviral access for all those needing it for treatment.

Consistent condom use and the substitution of condoms with potential HIV prevention methods of lower or unknown effectiveness are important concerns in the development of new prevention technologies. This qualitative study explored obstacles to consistent condom use with the diaphragm in MIRA, an HIV prevention trial in South Africa and Zimbabwe. We conducted 26 focus group discussions (FGDs) with 206 women and 7 FGDs and 10 in-depth interviews with 41 male partners of intervention-arm women. The belief that the diaphragm/gel prevented HIV, women's difficulties negotiating condom use, and men's unawareness that using the products together was recommended were obstacles to consistent condom use with the diaphragm/gel. Concerns about protection from HIV and pregnancy, recognition that the diaphragm was not yet proven to prevent HIV or sexually transmitted infections, and the trial context were facilitators. Understanding selective study product use in HIV prevention trials may inform improved adherence counseling and male involvement strategies.

Objective To evaluate a multi-pronged approach to promote dual contraceptive use by women within heterosexual HIV-1 serodiscordant partnerships. Methods For 213 HIV-1 serodiscordant couples in Thika, Kenya participating in an HIV-1 prevention clinical trial, contraceptive promotion was initiated through a multi-pronged intervention that included staff training, couples family planning sessions, and free provision of hormonal contraception on-site. Contraceptive use and pregnancy incidence were compared between two time periods (before versus after June 2007, when the intervention was initiated) and between Thika and other Kenyan trial sites (Eldoret, Kisumu, and Nairobi). Generalized estimating equations and Andersen-Gill proportional hazards modeling were used. Results Non-barrier contraceptive use increased after implementation of the intervention: from 31.5% to 64.7% of visits among HIV-1 seropositive women (odds ratio [OR] 4.0, 95% confidence interval [CI] 3.0–5.3) and from 28.6% to 46.7% of visits among HIV-1 seronegative women (OR 2.2, 95% CI 1.4–3.5). In comparison, at the other Kenyan sites, where the intervention was not implemented, contraceptive use changed minimally, from 15.6% to 22.3% of visits for HIV-1 seropositive women and from 13.6% to 12.7% among HIV-1 seronegative women. Self-reported condom use remained high during follow-up. Pregnancy incidence at the Thika was significantly lower after compared with before June 2007 (hazard ratio [HR] 0.2, 95% CI 0.1–0.6), and was approximately half that at other Kenyan sites during the intervention period (HR 0.5, 95% CI 0.3–0.8). Conclusions A multi-pronged family planning intervention can lead to high non-barrier contraceptive uptake and reduced pregnancy incidence among women in HIV-1 serodiscordant partnerships.

In the United States, 46% of high school students have had sexual intercourse and potentially are at risk for human immunodeficiency virus (HIV) infection, other sexually transmitted diseases (STDs), and pregnancy. The National HIV/AIDS Strategy for the United States recommends educating young persons about HIV before they begin engaging in behaviors that place them at risk for HIV infection. The Community Preventive Services Task Force (CPSTF) also recommends risk reduction interventions to prevent HIV, other STDs, and pregnancy among adolescents. To estimate changes in the percentage of secondary schools that teach specific HIV, other STD, and pregnancy risk reduction topics, a key intervention consistent with those supported by the National HIV/AIDS Strategy and CPSTF, CDC analyzed 2008 and 2010 School Health Profiles data for public secondary schools in 45 states. This report summarizes the results of those analyses, which indicated that in 2010, compared with 2008, the percentage of secondary schools teaching 11 topics on HIV, other STD, and pregnancy prevention in a required course in grades 6, 7, or 8 was significantly lower in 11 states and significantly higher in none; the percentage of secondary schools teaching eight topics in a required course in grades 9, 10, 11, or 12 was significantly lower in one state and significantly higher in two states; and the percentage of secondary schools teaching three condom-related topics in a required course in grades 9, 10, 11, or 12 was significantly lower in eight states and significantly higher in three states. Secondary schools can increase efforts to teach all age-appropriate HIV, other STD, and pregnancy prevention topics to help reduce risk behaviors among students.

Islamic values portraying sex outside of marriage as sinful are often believed to contribute to HIV transmission as they reject safe-sex practices. Moreover, stigma associated with sinful behaviour is frequently assumed to interfere with access to care for those infected. In contrast, adherence to religious values such as abstinence is viewed as an explanation for the relatively low incidence of HIV infection in Islamic populations. Inspired by this debate, a study was conducted into the possibilities of using Islamic texts as a starting point for health promotion addressing HIV infection and HIV/AIDS-related stigma in Lamu, a Muslim community in Kenya. The study also explored the potential role of Lamu's Islamic leaders in the delivery of that health promotion. In collaboration with Islamic leaders, texts were identified that applied to sexual conduct, health, stigma and the responsibilities of Islamic leaders towards their congregations. In spite of the association of HIV with improper sexual behaviour, Islamic texts offer a starting point for tackling HIV transmission and HIV/AIDS-related stigma. Under particular conditions, the identified Islamic texts may even justify the promotion of safer-sex methods, including condom use.

HIV/AIDS has the unfortunate distinction of being one of the most devastating epidemics of the twentieth century. By the end of June, 1999, 420,201 deaths in persons with AIDS had been reported in the United States. While HIV/AIDS patients are currently living longer as a result of more effective and complex treatments, no vaccination or cure has yet been discovered. Over the years, the HIV/AIDS epidemic has become multifactorial and currently affects several different special population groups. Individuals who are at high risk for becoming infected with HIV or who already suffer from HIV/AIDS can benefit greatly from the interventions of psychiatrists or other mental health professionals. It is important that psychiatrists collaborate very closely with infectious disease specialists in the management of HIV/AIDS and its psychological sequelae. The authors describe the psychiatric conditions that most often occur in association with HIV/AIDS: mood disorders, anxiety disorders, substance-related disorders, psychotic disorders, insomnia and sleep disorders, delirium, dementia, and pain syndromes. We present guidelines for diagnosis and psychopharmacological and psychotherapeutic treatment of these disorders in patients with HIV/AIDS. The article concludes with a discussion of prevention strategies that can be used in a mental health treatment setting and special issues related to treating HIV/AIDS in certain special population groups.

Desertification is one of the main factors determining poverty, long-term socio-economic problems, natural resources depletion and disturbances in rural communities living at the Coquimbo Region drylands (North-Central Chile). The Chilean State, along with private initiatives, have invested 473.6 Million dollars (1976 to 2008) to recover degraded areas through afforestation and soil management of 1,373,758 hectares. However, there is no information about the impact of the practices and changes experienced by the local stakeholders. Therefore, there is a need for a comprehensive evaluation considering both socioeconomic and biophysical aspects. To this end, a Protocol on Integrated Assessment (IAPro, PRACTICE project) was applied in two rural communities, involving communal afforested sites and their adjacent degraded drylands: El Sauce (ES, Limarí province) and Las Cañas (LC, Choapa province), Coquimbo Region. Participatory afforestation and soil conservation projects were implemented at both sites by the Chilean National Forestry Service (CONAF) in agreement with each local community (Jiménez y Tapia Agricultural Community at ES and Las Cañas de Choapa Peasant's Community at LC). The protocol involved 7 steps: (1) Stakeholder platform identification and engagement; (2) Baseline assessment and selection of site-specific indicators; (3) Integration and weighting of common and site-specific indicators; (4) Data collection; (5) Integrating and perspectives on a MCDA (Multi-Criteria Decision Analysis); (6) Collective Integrated assessment and knowledge sharing; (7) Dissemination. Interviews involved local and institutional stakeholders related to both sites' implementation, administration and/or local impacts. For the ES site, 5 actions were defined and assessed: No action (control); fences; mechanic and biological practices (soil stabilization, runoff control on slopes); runoff control in micro-basins, gullies and ravines; and footpath for educational and

There remains a profound need for innovative and effective interventions designed for young men who have sex with men (YMSM) generally, and racial and ethnic minority YMSM, YMSM living in rural communities, and low-income YMSM, particularly, to prevent HIV and improve health outcomes in the United States. This introduction to this theme issue, "Behavioral HIV Prevention Interventions for Diverse YMSM," of AIDS Education and Prevention identifies some of the research needs, priorities, and opportunities that emerged during a seminal NIMHD-sponsored workshop on HIV prevention behavioral interventions for diverse YMSM. It provides researchers, practitioners, and federal partners guidance in next steps to reduce the impact of the HIV epidemic among YMSM. The needs, priorities, and opportunities identified serve as a foundation to push both the science and the practice of HIV prevention forward. We recognize that considerably more research is needed, and this issue highlights intervention research-where we have been and where we should go. With the disparities faced by YMSM, we must act rapidly to do the work it will take to meet their prevention needs, reduce infections, and save lives.

Governments and donors are investing considerable resources on HIV prevention in order to scale up these services rapidly. Given the current economic climate, providers of HIV prevention services increasingly need to demonstrate that these investments offer good 'value for money'. One of the primary routes to achieve efficiency is to take advantage of economies of scale (a reduction in the average cost of a health service as provision scales-up), yet empirical evidence on economies of scale is scarce. Methodologically, the estimation of economies of scale is hampered by several statistical issues preventing causal inference and thus making the estimation of economies of scale complex. In order to estimate unbiased economies of scale when scaling up HIV prevention services, we apply our analysis to one of the few HIV prevention programmes globally delivered at a large scale: the Indian Avahan initiative. We costed the project by collecting data from the 138 Avahan NGOs and the supporting partners in the first four years of its scale-up, between 2004 and 2007. We develop a parsimonious empirical model and apply a system Generalized Method of Moments (GMM) and fixed-effects Instrumental Variable (IV) estimators to estimate unbiased economies of scale. At the programme level, we find that, after controlling for the endogeneity of scale, the scale-up of Avahan has generated high economies of scale. Our findings suggest that average cost reductions per person reached are achievable when scaling-up HIV prevention in low and middle income countries.

Objective To develop data collection methods suitable to obtain data to assess the costs, cost-efficiency, and cost-effectiveness of eight types of HIV prevention programs in five countries. Data Sources/Study Setting Primary data collection from prevention programs for 2002–2003 and prior years, in Uganda, South Africa, India, Mexico, and Russia. Study Design This study consisted of a retrospective review of HIV prevention programs covering one to several years of data. Key variables include services delivered (outputs), quality indicators, and costs. Data Collection/Extraction Methods Data were collected by trained in-country teams during week-long site visits, by reviewing service and financial records and interviewing program managers and clients. Principal Findings Preliminary data suggest that the unit cost of HIV prevention programs may be both higher and more variable than previous studies suggest. Conclusions A mix of standard data collection methods can be successfully implemented across different HIV prevention program types and countries. These methods can provide comprehensive services and cost data, which may carry valuable information for the allocation of HIV prevention resources. PMID:15544641

The universal precautions recommended by the US Centers for Disease Control (CDC), Atlanta, for the prevention of HIV (human immunodeficiency virus) transmission to health care workers are widely accepted, despite little documentation of their effectiveness and efficiency. We reviewed the evidence on the risk of HIV transmission to hospital workers and the effectiveness of the universal precautions. We also evaluated the costs of implementing the recommendations in a 450-bed acute care teaching hospital in Hamilton, Ont. On the basis of aggregated results from six prospective studies the risk of HIV seroconversion among hospital workers after a needlestick injury involving a patient known to have AIDS (acquired immune deficiency syndrome) is 0.36% (upper 95% confidence limit 0.67%); the risk after skin and mucous membrane exposure to blood or other body fluids of AIDS patients is 0% (upper 95% confidence limit 0.38%). We estimated that 0.038 cases of HIV seroconversion would be prevented annually in the study hospital if the CDC recommendations were followed. The incremental cost of implementing the universal precautions was estimated to be about $315,000 per year, or over $8 million per case of HIV seroconversion prevented. If all HIV-infected workers were assumed to have AIDS within 10 years of infection the of the program would be about $565,000 per life-year saved. When less conservative, more probable assumptions were applied the best estimate of the implementation cost was $128,862,000 per case of HIV seroconversion prevented. The universal precautions implemented in the study hospital were not found to be efficacious or cost-effective. To minimize the already small risk of HIV transmission in hospitals the sources of risk of percutaneous injury should be better defined and the design of percutaneous lines, needles and surgical equipment as well as techniques improved. Preventive measures recommended on the basis of demonstrated efficacy and aimed at routes

This paper addresses how London gay men use the internet to meet sexual partners, or for e-dating. Based on qualitative interviews conducted face-to-face or via the internet, this research develops an account of how information technologies mediate the negotiation of identity and risk in connection with sexual practice. E-dating itself is a bricolage, or heterogeneous DIY practice of internet-based-communication (IBC). A central aspect of IBC is "filtering" in and out prospective e-dates based on the images and texts used to depict sexual identities. Interpretations and depictions of personal HIV risk management approaches in IBC are framed by the meanings of different identities, such as the stigma associated with being HIV positive. This paper argues for a sexualities perspective in a theory of network society. Further, HIV prevention in e-dating can potentially be addressed by considering the interplay of the HIV prevention imperatives associated with different HIV serostatus identities. There is a case for encouraging more explicit IBC about risk in e-dating and incorporating the expertise of e-daters in prevention activity. There is also a need to rethink traditional conceptions of risk management in HIV prevention to make space for the risk management bricolage of network society.

Purpose of review Oral preexposure prophylaxis (PrEP) has shown HIV preventive efficacy for several key populations at risk for HIV infection including MSM and heterosexual men and women in HIV serodiscordant relationships. An efficacy trial of daily oral tenofovir among people who inject drugs (IDU) is underway in Thailand. Recent findings Although efficacy data is pending, there is emerging biological and public health plausibility data suggesting the utility of PrEP as an effective component of combination HIV prevention for IDU. Drawing from studies characterizing adherence to antiretroviral therapy for IDU, there are a range of scientific and operational considerations for the potential use of PrEP for IDU. We review here the available literature on the potential use of PrEP for IDU, barriers to uptake and adherence, and potential implementation science questions, which could address, and potently increase, the effectiveness of this intervention. Summary IDU remain the most underserved population in the HIV response worldwide, and have a marked gap in prevention services, making PrEP a potentially promising addition to the prevention toolkit for people who use drugs and, for those already living with HIV infection, for their spouses and other sexual partners.

Sexually explicit media (SEM) have been used in HIV-prevention advertisements to engage men who have sex with men (MSM), and to communicate content. These advertisements exist within larger discourses, including a dominant heternormative culture, and a growing homonormative culture. Cognizant of these hegemonic cultures, this analysis examined the acceptable level of sexual explicitness in prevention advertisements. 79 MSM participated in 13 online focus groups, which were part of a larger study of SEM. Three macro-themes—audience, location and community representation—emerged from the analysis, as did the influence of homonormativity on the acceptability of SEM in HIV-prevention messages.

High rates of smoking among persons living with HIV (PLWH) may reduce the effectiveness of HIV treatment and contribute to significant morbidity and mortality. Factors associated with smoking in PLWH include mental health comorbidity, alcohol and drug use, health-related quality of life, smoking among social networks and supports, and lack of access to care. PLWH smokers are at a higher risk of numerous HIV-associated infections and non-HIV related morbidity, including a decreased response to antiretroviral treatment, impaired immune functioning, reduced cognitive functioning, decreased lung functioning, and cardiovascular disease. Seventeen smoking cessation interventions were identified, of which seven were randomized controlled trials. The most effective studies combined behavioral and pharmacotherapy treatments that incorporated comprehensive assessments, multiple sessions, and cognitive-behavioral and motivational strategies. Smoking cessation interventions that are tailored to the unique needs of diverse samples and incorporate strategies to reduce the risk of relapse are essential to advancing health outcomes in PLWH.

Background The Centers for Disease Control and Prevention recommends that sexually active men who have sex with men (MSM) in the United States test for human immunodeficiency virus (HIV) at least three times per year, but actual testing frequency is much less frequent. Though mHealth is a popular vehicle for delivering HIV interventions, there are currently no mobile phone apps that target MSM with the specific aim of building an HIV testing plan, and none that focuses on developing a comprehensive prevention plan and link MSM to additional HIV prevention and treatment resources. Previous research has suggested a need for more iterative feedback from the target population to ensure use of these interventions. Objective The purpose of this study is to understand MSM’s preferences for functionality, format, and design of a mobile phone-based HIV prevention app and to examine MSM’s willingness to use an app for HIV prevention. Methods We conducted focus group discussions with 38 gay and bisexual men, with two in-person groups in Atlanta, two in Seattle, and one online focus group discussion with gay and bisexual men in rural US regions. These discussions addressed MSM’s general preferences for apps, HIV testing barriers and facilitators for MSM, and ways that an HIV prevention app could address these barriers and facilitators to increase the frequency of HIV testing and prevention among MSM. During focus group discussions, participants were shown screenshots and provided feedback on potential app functions. Results Participants provided preferences on functionality of the app, including the type and delivery of educational content, the value of interactive engagement, and the importance of social networking as an app component. Participants also discussed preferences on how the language should be framed for the delivery of information, identifying that an app needs to be simultaneously fun and professional. Privacy and altruistic motivation were considered to be

There is limited information on the impact of the HIV/AIDS epidemic on Latino migrant workers (LMWs), although available data indicate that this community is being disproportionally affected. The need for prevention programs that address the specific needs of LMWs is becoming well recognized. HIV prevention interventions that train and employ community health workers are a culturally appropriate way to address the issues of community trust and capacity building in this community. This article describes the Latino Migrant Worker HIV Prevention Program and its efforts to train and engage community health workers in the prevention of HIV among LMWs in South Florida.

The risk of HIV in the Latino population in the United States is increasing. This population has a disproportionate number of new HIV cases, with the largest burden in the seventeen southern states. The purpose of this study is to assess risk factors for HIV among HIV-positive Latinos in care in New Orleans, Louisiana, through a retrospective chart review. The Chi square test of proportions, Student's t-test, and Wilcox rank sum test were used to test differences by sex and immigration status. Men were more likely to be incarcerated, use drugs, and drink alcohol. Undocumented Latinos were younger and had increased language barriers. Legally documented participants were more likely to use drugs, have a psychiatric diagnosis, and syphilis. Understanding the complex risk factors that surround HIV in the Latino population is useful for the development of effective and comprehensive prevention programs.

The efficacy of a computer-based interactive multimedia HIV/AIDS prevention program for men with intellectual disability (ID) was examined using a quasi-experimental within-subjects design. Thirty-seven men with mild to moderate intellectual disability evaluated the program. The pretest and posttest instruments assessed HIV/AIDS knowledge (high-risk fluids, HIV transmission, and condom facts) and condom application skills. All outcome measures showed statistically significant gains from pretest to posttest, with medium to large effect sizes. In addition, a second study was conducted with twelve service providers who work with men with ID. Service providers reviewed the HIV/AIDS prevention program, completed a demographics questionnaire, and a program satisfaction survey. Overall, service providers rated the program highly on several outcome measures (stimulation, relevance, and usability).

Voluntary medical male circumcision (VMMC) is capable of reducing the risk of sexual transmission of HIV from females to males by approximately 60%. In 2007, the WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended making VMMC part of a comprehensive HIV prevention package in countries with a generalized HIV epidemic and low rates of male circumcision. Modeling studies undertaken in 2009-2011 estimated that circumcising 80% of adult males in 14 priority countries in Eastern and Southern Africa within five years, and sustaining coverage levels thereafter, could avert 3.4 million HIV infections within 15 years and save US$16.5 billion in treatment costs. In response, WHO/UNAIDS launched the Joint Strategic Action Framework for accelerating the scale-up of VMMC for HIV prevention in Southern and Eastern Africa, calling for 80% coverage of adult male circumcision by 2016. While VMMC programs have grown dramatically since inception, they appear unlikely to reach this goal. This review provides an overview of findings from the PLOS Collection "Voluntary Medical Male Circumcision for HIV Prevention: Improving Quality, Efficiency, Cost Effectiveness, and Demand for Services during an Accelerated Scale-up." The use of devices for VMMC is also explored. We propose emphasizing management solutions to help VMMC programs in the priority countries achieve the desired impact of averting the greatest possible number of HIV infections. Our recommendations include advocating for prioritization and funding of VMMC, increasing strategic targeting to achieve the goal of reducing HIV incidence, focusing on programmatic efficiency, exploring the role of new technologies, rethinking demand creation, strengthening data use for decision-making, improving governments' program management capacity, strategizing for sustainability, and maintaining a flexible scale-up strategy informed by a strong monitoring, learning, and evaluation platform.

Vaginal HIV transmission accounts for the majority of new infections worldwide. Currently, multiple efforts to prevent HIV transmission are based on pre-exposure prophylaxis with various antiretroviral drugs. Here, we describe two novel nanoformulations of the reverse transcriptase inhibitor rilpivirine for pericoital and coitus-independent HIV prevention. Topically applied rilpivirine, encapsulated in PLGA nanoparticles, was delivered in a thermosensitive gel, which becomes solid at body temperature. PLGA nanoparticles with encapsulated rilpivirine coated the reproductive tract and offered significant protection to BLT humanized mice from a vaginal high-dose HIV-1 challenge. A different nanosuspension of crystalline rilpivirine (RPV LA), administered intramuscularly, protected BLT mice from a single vaginal high-dose HIV-1 challenge one week after drug administration. Using transmitted/founder viruses, which were previously shown to establish de novo infection in humans, we demonstrated that RPV LA offers significant protection from two consecutive high-dose HIV-1 challenges one and four weeks after drug administration. In this experiment, we also showed that, in certain cases, even in the presence of drug, HIV infection could occur without overt or detectable systemic replication until levels of drug were reduced. We also showed that infection in the presence of drug can result in acquisition of multiple viruses after subsequent exposures. These observations have important implications for the implementation of long-acting antiretroviral formulations for HIV prevention. They provide first evidence that occult infections can occur, despite the presence of sustained levels of antiretroviral drugs. Together, our results demonstrate that topically- or systemically administered rilpivirine offers significant coitus-dependent or coitus-independent protection from HIV infection. PMID:26271040

This review describes the use of social networking sites (SNS) in the context of primary prevention of HIV. A review was conducted to assess the published literature for HIV interventions using SNS. Sixteen articles describing twelve interventions were included. SNS were instrumental in recruiting hard-to-reach populations within a short amount of time; were able to reach wide audiences beyond the targeted population for HIV prevention campaigns; and helped to significantly reduce sexual risk behaviors and increase HIV testing. SNS are a viable option to recruit hidden populations, engage the target audience, and disseminate HIV prevention messages. Researchers should use SNS to generate sampling frames that can be used to select participants. Practitioners should use SNS to post images of preventive behavior within health promotion campaigns. Researchers should use multiple SNS platforms to engage participants. As more studies are published using SNS for HIV prevention, meta-analyses will be needed.

The meeting, HIV/AIDS and African American Women: A Consultation Supporting CDC's Heightened National Response to the HIV/AIDS Crisis among African Americans, provided a forum to address gaps in prevention and HIV/AIDS infection for African American women. Health researchers, community-based organization leaders, and representatives from both healthcare and non-healthcare sectors took this opportunity to discuss and develop a variety of priorities and suggestions for HIV/AIDS prevention. Four focus areas were provided for meeting attendees to promote discussion and strategy development. The resulting list of priorities and suggestions for HIV/AIDS prevention may provide future steps for researchers, communities, and physicians to increase prevention and decrease infection rates. Novel, innovative, and participatory approaches are needed within and outside the public arena to decrease the gaps in HIV/AIDS prevention for African American women.

Introduction Although biomedical HIV prevention efforts have seen a number of recent promising developments, behavioural interventions have often been described as failing. However, clear lessons have been identified from past efforts, including the need to address influential social, economic and legal structures; to tailor efforts to local contexts; and to address multiple influencing factors in combination. Despite these insights, there remains a pervasive strategy to try to achieve sexual behaviour change through single, decontextualized, interventions or sets of activities. With current calls for structural approaches to HIV as part of combination HIV prevention, though, there is a unique opportunity to define a structural approach to HIV prevention as one which moves beyond these past limitations and better incorporates our knowledge of the social world and the lessons from past efforts. Discussion A range of interlinked concepts require delineation and definition within the broad concept of a structural approach to HIV. This includes distinguishing between “structural factors,” which can be seen as any number of elements (other than knowledge) which influence risk and vulnerability, and “structural drivers,” which should be reserved for situations where an empirically established relationship to a target group is known. Operationalizing structural approaches similarly can take different paths, either working to alter structural drivers or alternatively working to build individual and community resilience to infection. A “structural diagnostic approach” is further defined as the process one undertakes to develop structural intervention strategies tailored to target groups. Conclusions For three decades, the HIV prevention community has struggled to reduce the spread of HIV through sexual risk behaviours with limited success, but equally with limited engagement with the lessons that have been learned about the social realities shaping patterns of

There has been a growing awareness of the importance of engaging communities in the development, testing, and eventual dissemination of biomedical strategies. Community engagement offers many benefits but comes with many challenges. This article will discuss these benefits and challenges and describe two examples of community engagement, Connect to Protect in the United States, and the South African Studies on HIV in Adolescents Project in South Africa, that represent investment in community engagement as preparation for biomedical HIV prevention clinical trials for youth.

Summary This report summarizes published findings of a community-based organization in New York City that evaluated and demonstrated the efficacy of the Many Men, Many Voices (3MV) human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevention intervention in reducing sexual risk behaviors and increasing protective behaviors among black men who have sex with men (MSM). The intervention addressed social determinants of health (e.g., stigma, discrimination, and homophobia) that can influence the health and well-being of black MSM at high risk for HIV infection. This report also highlights efforts by CDC to disseminate this evidence-based behavioral intervention throughout the United States. CDC's Office of Minority Health and Health Equity selected the intervention analysis and discussion to provide an example of a program that might be effective for reducing HlV infection- and STD-related disparities in the United States. 3MV uses small group education and interaction to increase knowledge and change attitudes and behaviors related to HIV/STD risk among black MSM. Since its dissemination by CDC in 2004, 3MV has been used in many settings, including health department- and community-based organization programs. The 3MV intervention is an important component of a comprehensive HIV and STD prevention portfolio for at-risk black MSM. As CDC continues to support HIV prevention programming consistent with the National HIV/AIDS Strategy and its high-impact HIV prevention approach, 3MV will remain an important tool for addressing the needs of black MSM at high risk for HIV infection and other STDs.

Latin American and Caribbean countries possess the capability and expertise to manage their own HIV/AIDS programs but still need help with financial capital and material resources for these programs to reach their potential. Latin American countries have been especially proactive in working with each other to share information and develop regional planning programs. The history of HIV program development in this region is briefly outlined. Countries are continuing to work together with each other and with the private sector to design and manage programs that prevent and/or treat HIV infection.

Background HIV is hyperendemic in Swaziland with a prevalence of over 25% among those between the ages of 15 and 49 years old. The HIV response in Swaziland has traditionally focused on decreasing HIV acquisition and transmission risks in the general population through interventions such as male circumcision, increasing treatment uptake and adherence, and risk-reduction counseling. There is emerging data from Southern Africa that key populations such as female sex workers (FSW) carry a disproportionate burden of HIV even in generalized epidemics such as Swaziland. The burden of HIV and prevention needs among FSW remains unstudied in Swaziland. Methods A respondent-driven-sampling survey was completed between August-October, 2011 of 328 FSW in Swaziland. Each participant completed a structured survey instrument and biological HIV and syphilis testing according to Swazi Guidelines. Results Unadjusted HIV prevalence was 70.3% (n = 223/317) among a sample of women predominantly from Swaziland (95.2%, n = 300/316) with a mean age of 21(median 25) which was significantly higher than the general population of women. Approximately one-half of the FSW(53.4%, n = 167/313) had received HIV prevention information related to sex work in the previous year, and about one-in-ten had been part of a previous research project(n = 38/313). Rape was common with nearly 40% (n = 123/314) reporting at least one rape; 17.4% (n = 23/314)reported being raped 6 or more times. Reporting blackmail (34.8%, n = 113/314) and torture(53.2%, n = 173/314) was prevalent. Conclusions While Swaziland has a highly generalized HIV epidemic, reconceptualizing the needs of key populations such as FSW suggests that these women represent a distinct population with specific vulnerabilities and a high burden of HIV compared to other women. These women are understudied and underserved resulting in a limited characterization of their HIV prevention, treatment, and care needs and

This article presents preliminary findings of a randomized HIV prevention study in Trinidad and Tobago in the Caribbean. The study centers on a family HIV workshop aimed at strengthening parenting skills that are empirically linked to reducing adolescent HIV exposure and other sexual risks. These skills include parental monitoring; educating youth about HIV, sex, and other sexually transmitted infections (STI's); and discussing cultural and interpersonal pressures to have sex. Participants include 180 primary caregivers and their 12-14-year-old adolescents randomized to either the Trinidad and Tobago family HIV Workshop (N = 92) or a general workshop (N = 88). Intervention and control group participants completed pretest and posttest measures on parenting and HIV risk outcomes. Compared to controls, intervention parents reported improvements in HIV knowledge (d = .79); attitudes toward AIDS (d = .42); general communication with adolescents (d = .94); conversations with adolescents about sex (d = .95); conversations about sexual risks and values (d = .43); monitoring of adolescents (d = .34); conflicts with adolescents (d = .30); and intensity of daily parenting hassles (d = .35). Intervention and control parents did not differ in behavioral control, use of positive parenting techniques, and expansion of support networks. Implications for addressing rising HIV risks among young people in Trinidad and Tobago and the Caribbean are discussed.
In the scientific literature on fertility and assisted reproduction, and in the corresponding area of clinical practice, increasing attention has been paid to two groups: people living with the human immunodeficiency virus (HIV) and gay men. However, research on fertility in the context of HIV focuses almost exclusively on heterosexual couples, whereas studies on non-heterosexual reproduction rarely mention HIV, despite the fact that, in many western countries, HIV prevalence among men who have sex with men is higher than ever before and men who have sex with men are the only group in which new HIV infections are on the rise. This review identifies links between reproduction, HIV and homosexuality, showing that, historically, they are closely intertwined, which has important implications for current issues facing HIV care and fertility services. Considering sex and parenthood as two different but related kinds of intimacy and kinship, the dual role semen plays in sexually transmitted infection and in assisted reproduction is discussed. The review reflects on the future of sperm donation and HIV prevention, asking whether two challenges that potentially face healthcare and medicine today - the shortage of 'high-quality' sperm and the 'surplus' of infected semen - could be addressed by a greater exchange of knowledge.

Contact with the criminal justice system, including incarceration, is a common experience for many people living with HIV/AIDS. Optimism has recently been expressed that correctional facilities could be important locations for Treatment-as-Prevention (TasP)-based initiatives. We review recent findings regarding the effect of incarceration on patterns of HIV transmission, testing, treatment initiation and retention. We found that the prevalence of HIV infection among incarcerated individuals remains higher than analogous non-incarcerated populations. Recent studies have shown that voluntary HIV/AIDS testing is feasible in many correctional facilities, although the number of previously undiagnosed individuals identified has been modest. Studies have implied enhanced linkage to HIV/AIDS treatment and care in jails in the United States was associated with improvements in the HIV cascade of care. However, for many individuals living with HIV/AIDS, exposure to the correctional system remains an important barrier to retention in HIV/AIDS treatment and care. Future research should evaluate structural interventions to address these barriers and facilitate the scale-up of TasP-based efforts among individuals living in correctional settings. PMID:24962285

HIV-serodiscordant couples face complicated choices between fulfilling reproductive desire and risking HIV transmission to their partners and children. Sexual HIV transmission can be dramatically reduced through artificial insemination and sperm washing, however most couples cannot access these resources. We propose that periconception pre-exposure prophylaxis (PrEP) could offer an important, complementary therapy to harm reduction counseling programs that aim to decrease HIV transmission for couples who choose to conceive. In this paper we describe the potential benefits of periconception PrEP and define critical points of clarification prior to implementation of PrEP as part of a reproductive health program. We consider sexual transmission risk, current risk reduction options, PrEP efficacy, cost, adherence, resistance, fetal toxicity, and impact of PrEP counseling on entry into health services. We address PrEP in the context of other periconception HIV prevention strategies, including antiretroviral treatment of the HIV-infected partner. We conclude that, should PrEP prove safe and efficacious in ongoing trials, periconception PrEP may offer a useful approach to minimize risk of HIV transmission for individuals of reproductive age in HIV-endemic countries.

With the growing incidence of HIV, there is a desperate need to develop simple, cheap and effective new ways of preventing HIV infection. Male circumcision reduces the risk of infection by about 60%, probably because of the removal of the Langerhans cells which are abundant in the inner foreskin and are the primary route by which HIV enters the penis. Langerhans cells form a vital part of the body's natural defence against HIV and only cause infection when they are exposed to high levels of HIV virions. Rather than removing this natural defence mechanism by circumcision, it may be better to enhance it by thickening the layer of keratin overlying the Langerhans cells, thereby reducing the viral load to which they are exposed. We have investigated the ability of topically administered oestrogen to induce keratinization of the epithelium of the inner foreskin. Histochemically, the whole of the foreskin is richly supplied with oestrogen receptors. The epithelium of the inner foreskin, like the vagina, responds within 24 hours to the topical administration of oestriol by keratinization, and the response persists for at least 5 days after the cessation of the treatment. Oestriol, a cheap, readily available natural oestrogen metabolite, rapidly keratinizes the inner foreskin, the site of HIV entry into the penis. This thickening of the overlying protective layer of keratin should reduce the exposure of the underlying Langerhans cells to HIV virions. This simple treatment could become an adjunct or alternative to surgical circumcision for reducing the incidence of HIV infection in men.

In 2002, we implemented a 4-year HIV prevention intervention for injection drug users (IDUs) in Lang Son Province, Vietnam, and Ning Ming County, Guangxi Province, China, a cross-border region seriously affected by inter-twined epidemics of heroin injection and HIV infection. The interventions involve peer education on HIV risk reduction and…

Gay families are constructed support networks that gay, bisexual, and transgender individuals of color form, often in response to societal marginalization and rejection from biological families. Research on these family structures has been scarce, with little focus on the experience of African American gay family networks in the South. The current grounded theory qualitative study focused on the experiences of 10 African American male and transgender individuals between the ages of 18 and 29 from gay families in the Mid-South, and explored the ways these families addressed safe-sex issues and human immunodeficiency virus (HIV) risk prevention. Results revealed that families can play a role in either increasing HIV risk (e.g., ignoring HIV issues, encouraging such unsafe behaviors as exchanging sex for money or drugs, stigmatizing HIV-positive people) or decreasing it (e.g., intensive, family-level prevention efforts at safe-sex practices and family support for HIV treatment adherence). The potential of these family networks for HIV prevention and adherence efforts is considered.
Unprotected anal sex has long been recognized as a risk factor for HIV transmission among men who have sex with men (MSM). In Africa, however, general denial of MSM existence and associated stigma discouraged research. To address this gap in the literature, partners conducted the first behavioral surveys of MSM in Kenya. The first study was to assess HIV risk among MSM in Nairobi, and the second study a pre-post intervention study of male sex workers in Mombasa. The 2004 behavioral survey of 500 men in Mombasa revealed that MSM were having multiple sexual partners and failed to access appropriate prevention counseling and care at Kenya clinics. A 2006 capture-recapture enumeration in Mombasa estimated that over 700 male sex workers were active, after which a pre-intervention baseline survey of 425 male sex workers was conducted. Awareness of unprotected anal sex as an HIV risk behavior and consistent condom use with clients was low, and use of oil-based lubricants high. Based on this information, peer educators were trained in HIV prevention, basic counseling skills, and distribution of condoms and lubricants. To assess impact of the interventions, a follow-up survey of 442 male sex workers was implemented in 2008. Exposure to peer educators was significantly associated with increased consistent condom use, improved HIV knowledge, and increased use of water-based lubricants. These results have provided needed information to the Government of Kenya and have informed HIV prevention interventions. PMID:24753921

Background Juvenile drug court offenders have benefited from evidence-based interventions addressing antisocial behavior, mental health and/or substance use; however, interventions addressing HIV risk behavior are lacking. This study presents pilot findings and lessons learned from a group-based HIV prevention intervention delivered to juvenile drug court offenders. Methods Participants were randomized to a 5-session HIV Prevention (n =29) or Health Promotion (n=28) condition and completed measures of sexual risk taking and substance use at baseline and 3 month post-intervention. Results No between-group differences by time emerged on measures of sexual risk-taking or other HIV-related behaviors and attitudes. Both groups improved their rates of HIV testing and decreased their substance use during sex over time. Conclusions Delivering an HIV prevention intervention to drug court offenders is feasible; however, more intensive interventions that incorporate multiple systems and address co-occurring mental health difficulties may be needed to affect sexual behavioral change among these high-risk court-involved youth.

Background Worldwide, an in Chile, the number of women living with HIV is increasing. Depression is considered a factor that interferes with HIV prevention. Depression may reach 41% among low income Chilean women. Depressed people are less willing to participate in behaviors that protect them against HIV. Objectives To analyze the impact of Mano a Mano-Mujer (MM-M) on depressive symptoms among Chilean women. Methods A quasi-experimental design was used to test the impact of MM-M, an HIV prevention intervention. The research was conducted in Santiago- Chile, a total of 400 women participated in the study (intervention group, n = 182; control group, n = 218). The intervention was guided by the social-cognitive model and the primary health model. The intervention consists of six two-hour sessions delivered in small groups. Sessions covered: HIV prevention, depression, partner's communication, and substance abuse. Face to face interviews were conducted at baseline and at 3 months follow-up Results At 3 months post-intervention, Chilean women who participated in MM-M significantly decreased their reported depressive symptoms. Conclusions MM-M provided significant benefits for women's depression symptoms. This study offers a model that address depression, a risk factor for HIV. It uses nurses as leaders for the screening of depressive symptoms and as facilitators of community interventions. PMID:22452388

Social scientific and public health literature on National Institutes of Health-funded HIV behavioural prevention science often assumes that this body of work has a strong biomedical epistemological orientation. We explore this assumption by conducting a systematic content analysis of all NIH-funded HIV behavioural prevention grants for men who have sex with men between 1989 and 2012. We find that while intervention research strongly favours a biomedical orientation, research into the antecedents of HIV risk practices favours a sociological, interpretive and structural orientation. Thus, with respect to NIH-funded HIV prevention science, there exists a major disjunct in the guiding epistemological orientations of how scientists understand HIV risk, on the one hand, and how they engineer behaviour change in behavioural interventions, on the other. Building on the extant literature, we suggest that the cause of this disjunct is probably attributable not to an NIH-wide positivist orientation, but to the specific standards of evidence used to adjudicate HIV intervention grant awards, including randomised controlled trials and other quantitative measures of intervention efficacy.

Most HIV prevention for sexual minority men and men who have sex with men targets risk behaviors (e.g., condom use) and helps <50% of participants. Bolstering resilience might increase HIV prevention's effectiveness. This systematic review identified resilience resources (protective factors) in high-risk, HIV-negative, sexual minority men. We reviewed PsycINFO, PsycARTICLES, MEDLINE, references, and Listservs for studies including sexual minority men with 1+ HIV risk factor (syndemics): childhood sexual abuse, partner abuse, substance abuse, or mental health symptoms. From 1356 articles screened, 20 articles met inclusion criteria. Across the articles, we identified and codified 31 resilience resources: socioeconomic (e.g., employment), behavioral coping strategies (e.g., mental health treatment), cognitions/emotions (e.g., acceptance), and relationships. Resilience resources were generally associated with lower HIV risk; there were 18 low-risk associations, 4 high-risk associations, 8 non-significant associations). We generated a set of empirically based resilience variables and a hypothesis to be evaluated further to improve HIV prevention.

Condom promotion remains a key component of HIV prevention programs, complimenting recent successes in biomedical HIV prevention. Although condom use has increased in much of East Africa, it remains substantially below optimal levels. Negative rumors about condoms have been documented in East Africa, yet the prevalence and effects of belief in the negative rumors have not been explored. This study evaluated levels of belief in negative rumors about condoms, developed a Negative Condom Beliefs Scale, and assessed its accuracy in predicting willingness to use condoms. A cross-sectional, cluster survey (n = 370) was conducted representing adults in two rural districts in Northern Tanzania in 2008. Item agreement ranged from 35 to 53% for the following rumors regarding condoms: causing cancer, having holes, containing HIV, having worms, and the worms causing HIV. Items loaded on a single latent factor and had high internal consistency and convergent validity. In a multivariate model, negative condom score (AOR = 0.67, 95% CI = 0.6, 0.8) was the strongest single predictor of willingness to use condoms, followed by greater perceived anonymity in acquiring condoms (AOR = 4.36, 95% CI = 2.2, 8.6) and higher condom self-efficacy (AOR = 4.24, 95% CI = 2.0, 8.9). Our findings indicate high levels of subscription to negative beliefs about condoms, with two out of three respondents affirming belief in at least one negative condom rumor. This study highlights the relation between condom rumor beliefs and willingness to use condoms, and indicates avenues for future research and means for improving the design of HIV prevention programs.

Trade-offs may exist between investments to promote health system strengthening, such as investments in facilities and training, and the rapid scale-up of HIV/AIDS services. We analyzed trends in expenditures to support the prevention of mother-to-child transmission of HIV in Kenya under the President's Emergency Plan for AIDS Relief (PEPFAR) from 2005 to 2010. We examined how expenditures changed over time, considering health system strengthening alongside direct treatment of patients. We focused on two organizations carrying out contracts under PEPFAR: the Elizabeth Glaser Pediatric AIDS Foundation and FHI360 (formerly Family Health International), a nonprofit health and development organization. We found that the average unit expenditure, or the spending on goods and services per mother living with HIV who was provided with antiretroviral drugs, declined by 52 percent, from $567 to $271, during this time period. The unit expenditure per mother-to-infant transmission averted declined by 66 percent, from $7,117 to $2,440. Meanwhile, the health system strengthening proportion of unit expenditure increased from 12 percent to 33 percent during the same time period. The analysis suggests that PEPFAR investments in prevention of mother-to-child transmission of HIV in Kenya became more efficient over time, and that there was no strong evidence of a trade-off between scaling up services and investing in health systems.

Capitalizing on emerging data suggesting that HIV preventive behaviors can be positively affected by Internet-based programs, we developed and tested CyberSenga, an Internet-based, comprehensive sexuality education program for adolescents in Mbarara, Uganda. Three hundred and sixty-six secondary school students were randomly assigned to either the 5-lesson program (+ booster) or a treatment-as-usual control. At three-month follow-up, intervention participants provided feedback on program acceptability. Six focus groups with intervention participants were additionally conducted after the final follow-up at 6 months. Data support a hypothesis of feasibility: Despite schedule interruptions, 95% of intervention participants completed all 5 modules; only 17% deviated from the once-a-week intended delivery schedule. Internet service was uninterrupted during the field period and, in general, the technology performed to specifications. The intervention also appears to be acceptable: 94% of intervention youth somewhat or strongly agreed that they learned a lot and 93% said they were somewhat or very likely to recommend the program. Although more than two in three youth somewhat or strongly agreed that the program talked too much about sex (70%) and condoms (75%), 89% somewhat or strongly disagreed that “I do not think kids like me should do the CyberSenga program”. Feedback from focus group participants further suggested that the content was generally acceptable and did not contradict local norms in most cases. In fact, despite concerns from some local stakeholders to the contrary, information about condoms did not appear to be confusing or contradictory for youth who were abstinent. Nonetheless, some of the sexual topics seemed to be unfamiliar or uncomfortable for some participants – particularly brief references to oral and anal sex. Together, both qualitative and quantitative data suggest that the program is a feasible and acceptable way of delivering HIV

Background Although emerging Treatment as Prevention models can be effective in reducing HIV incidence among high-risk populations, many HIV infected individuals remain undiagnosed or fail to engage in HIV care. Methods This study examined the factors associated with HIV testing and care among a population of substance using female sex workers. Results Recent HIV testing was associated with higher education level, having a regular health care provider or clinic, recent crack use, and higher sexual risk behaviors; HIV treatment utilization was associated with higher levels of social support, having a regular health care provider or clinic, housing stability and insurance coverage. Qualitative data revealed HIV-related stigma, denial, social isolation, and substance use as barriers to HIV testing and treatment; social support and accessibility of services were key enablers. Conclusions Improving HIV testing and linkage to treatment among female sex workers will require structural initiatives to reduce stigma and increase service seeking support. PMID:25130245
Safe, cost-effective interventions are being developed to reduce HIV transmission to children, suitable for lower income countries such as Tanzania. The interventions include Nevirapine treatment, replacement feeding, exclusive breast-feeding and heat-treating breast milk. This article reports on research to explore factors, which may influence the acceptability of these interventions. Data collection methods used were qualitative in-depth interviews with 12 health workers and focus group discussions with five community groups. Findings are presented with reference to the theory of diffusion of innovation, which seeks to explain how new ideas and products are disseminated through a community. Respondents describe the factors that may help and hinder this process. They propose ways to maximize this diffusion, such as integrating HIV and antenatal services, encouraging male participation, community-wide education, offering free HIV testing, and training health workers as change agents.

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.

HIV infection is spreading among the poor, women, and migrant communities in the interior of Northeast Brazil. The research focused on different configurations, beliefs, representations, and forms of social organization of behavior thought to be associated with the population's capacity to efficiently follow AIDS prevention measures. Participants located in neighborhoods known for having large migrant populations were identified by Family Health Program Workers in Fortaleza and Teresina. The study adopted a qualitative methodology. Several belief-system concepts and values, as well as the social organization of sexuality revealed in the study, represent obstacles both to AIDS prevention and condom use. Hunger, lack of prospects, and fear are associated with a social situation of poverty, exclusion, prejudice, and total absence of basic human rights. When examined together, these elements define different configurations in the migrants' increased vulnerability to HIV/AIDS. The groups' increased vulnerability relates to the socioeconomic complexity that must be considered in HIV/AIDS control and prevention programs.

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.

Introduction HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP). Discussion Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits. Conclusions Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies for delivering oral Pr

Abstract Despite the Mozambique government's efforts to curb human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), national prevalence is 11.5% and support is needed to expand HIV-related services and improve program quality. Positive prevention (PP) programs, which prioritize HIV prevention with people living with HIV and AIDS (PLHIV), have been recognized as an important intervention for preventing new HIV infections. To address this, an evidence-based PP training intervention was implemented with HIV healthcare providers in Mozambique. This study focuses on the acceptability and feasibility of a PP intervention in HIV clinics from the healthcare provider perspective. In-depth interviews were conducted with 31 healthcare providers from three provinces who participated in PP trainings in Mozambique. Interview data were coded using content analysis. Study data suggest that healthcare providers found PP acceptable, feasible to implement in their HIV work in clinic settings, and valued this strategy to improve HIV prevention. The PP training also led providers to feel more comfortable counseling their patients about prevention, with a more holistic approach that included HIV testing, treatment and encouraging PLHIV to live positively. While overall acceptance of the PP training was positive, several barriers to feasibility surfaced in the data. Patient-level barriers included resistance to disclosing HIV status due to fear of stigma and discrimination, difficulty negotiating for condom use, difficulty engaging men in testing and treatment, and the effects of poverty on accessing care. Providers also identified work environment barriers including high patient load, time constraints, and frequent staff turnover. Recognizing PP as an important intervention, healthcare providers should be trained to provide comprehensive prevention, care and treatment for PLHIV. Further work is needed to explore the complex social dynamics and cultural challenges

AIDS is increasing almost four times as fast among women, yet lesbians and bisexual women are among the least studied, least understood and most elusive populations affected by the AIDS epidemic. This paper reports the results of community-level HIV prevention research designed: (a) to examine the knowledge, perceptions, social contingencies and political constraints affecting the HIV risk taking of lesbians and bisexual women; and (b) to offer them context specific HIV prevention education. The study was a peer educator-based intervention project situated in San Francisco's women's bars, dance clubs, and sex clubs to reach socially and sexually active lesbians and bisexual women in natural settings. Between June 1992 and May 1993, ethnographic interviews were conducted with 626 women attending the bars and clubs; group presentations at these locales reached 1,315 women. The structure of the intervention was effective in prompting interest in HIV prevention information and intent to change behavior. The resultant cultural analysis details risk behaviors lesbians and bisexual women participate in, myriad constraints they face in trying to enact safer behaviors, gaps in knowledge, difficulties comprehending the relevance of HIV prevention, and risk reduction strategies commonly employed.

The recent literature on community-based participatory research (CBPR) approaches to preventing HIV infection in diverse communities was systematically reviewed as part of the planning process for a new study. Published HIV prevention studies that employed CBPR methods were identified for the period January 1, 2005 to April 30, 2014 using PubMed databases and MeSH term and keyword searches. A total of 44 studies on CBPR and HIV or AIDS prevention were identified, of which 3 focused on adolescents, 33 on adults, and 8 on both adolescents and adults. A variety of at-risk populations were the focus of the studies including men who have sex with men, African American or Hispanic men, and African American or Hispanic women. Few studies focused on Asian/Pacific Islander or American Indian populations in the U.S. Six studies employed CBPR methods to address HIV prevention in church settings. Many of the studies were limited to formative research (ethnographic research, in-depth interviews of key informants, or focus groups). Other studies had a pre-/post-test design, quasi-experimental, or randomized design. Additional CBPR studies and faith-based interventions are needed with adequate sample sizes and rigorous study designs to address lack of knowledge of HIV and inadequate screening in diverse communities to address health disparities.

HIV is frequently transmitted in the context of partners in a committed relationship, thus couples-focused HIV prevention interventions are a potentially promising modality for reducing infection. We conducted a systematic review of studies testing whether couples-focused behavioral prevention interventions reduce HIV transmission and risk behavior. We included studies using randomized controlled trial designs, quasi-randomized controlled trials and nonrandomized controlled studies. We searched five electronic databases and screened 7628 records. Six studies enrolling 1,084 couples met inclusion criteria and were included in this review. Results across studies consistently indicated that couples-focused programs reduced unprotected sexual intercourse and increased condom use compared with control groups. However, studies were heterogeneous in population, type of intervention, comparison groups, and outcomes measures, and so meta-analysis to calculate pooled effects was inappropriate. Although couples-based approaches to HIV prevention appear initially promising, additional research is necessary to build a stronger theoretical and methodological basis for couples-based HIV prevention, and future interventions must pay closer attention to homosexual couples, adolescents and young people in relationships.

Sexually acquired human immunodeficiency virus (HIV) infection continues to be the major source of HIV infection in the USA. Preventing sexual transmission of HIV can be accomplished through patient behaviour change. Such behaviour change can also decrease risk of other sexually transmitted diseases (STDs) and unwanted pregnancies, both far more common problems than HIV infection. Primary care physicians and other providers can increase patients' safe sex practices by conducting effective sexual risk assessment (RA) and risk reduction (RR) counselling, but physicians both infrequently and incompletely do sexual RA and RR. A programme was developed to improve primary care physicians' prevention practice using Simulated Patient Instructors (SPIs) and mailed educational materials. Programme evaluations showed improved sexual RA and RR practice both by self-report as well as by observation by Simulated Patient Evaluators (SPEs). This paper briefly reviews these findings and then presents adaptations made to improve the programme's content, decrease its cost and increase its availability for training many other care providers. Evaluation of the adapted programme indicates that content and training methods are highly regarded by a diverse array of trainees. To disseminate the modified programme beyond the local area, a Train-the-Trainer programme and manual have been developed, including discussion of recruiting, training and using SPIs for sexual risk reduction. Wider use of this training, as well as more effective and more readily available STD/HIV prevention training, are needed to attain national goals of provider clinical prevention practice.

Female sex workers (FSWs) who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers’ economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers’ relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

Despite the well-documented role of highly co-endemic biological cofactors in facilitating HIV transmission and the availability of comparatively inexpensive tools to control them, cofactor-related interventions are only hesitantly included into African HIV prevention strategies. Against this background, this study analyzes political obstacles to policy-uptake of evidence concerning structural HIV prevention. The data used stem from fieldwork conducted in Tanzania between 2007 and 2009. They include 92 in-depth interviews with key AIDS policymakers and observations of 8 national-level policy meetings. Adopting a political economy perspective, the study shows that 1) assuming cost-aversion as a spontaneous reflex of policymakers is empirically wrong and analytically misleading, 2) that political constituencies induce a path dependence of allocative decisions inconducive to structural prevention, 3) that interventions' political attractiveness depends on the nature of their outputs and the expected temporality of political returns, 4) that policy fragmentation entailed by vertical disease control disfavours the consideration of broader causalities, and 5) that cofactor-based measures are hampered by policymakers' perception of structural prevention as being excessively complex and ultimately tantamount to poverty eradication. Confronting the policy players' reading of the Tanzanian situation with recent and classical literature on evidence-based decision-making and the politics of public health, this paper shows that, far from being strictly evidence-driven, HIV prevention policies result from a politically negotiated aggregation of competing, frequently non-optimizing rationalities. A realistic appraisal of policy processes suggests that the failure to consider the invariably political nature of HIV-related policymaking hampers the formulation of effective, politically informed strategies for positive change. Consequently, developing policy practitioners

HIV infection among men who have sex with men, particularly in Thai urban settings and among younger cohorts, is escalating. HIV testing and counseling (HTC) are important for prevention and obtaining treatment and care. We examine data from a 2013 survey of males, 15-24 years, reporting past-year sex with a male and living in Bangkok or Chiang Mai. Almost three quarters of young MSM (YMSM) in Bangkok and only 27 % in Chiang Mai had an HIV test in the previous year. Associations for HIV testing varied between cities, although having employment increased the odds of HIV testing for both cities. In Bangkok, family knowledge of same sex attraction and talking to parents/guardians about HIV/AIDS had higher odds of HIV testing. Expanded HTC coverage is needed for YMSM in Chiang Mai. All health centers providing HTC, including those targeting MSM, need to address the specific needs of younger cohorts.
Background Building on its National Tobacco Control Policy initiated in 2000, Vietnam is currently considering introducing a comprehensive law to strengthen the implementation of tobacco control policy. This study analyses the positions of key stakeholders in the development of tobacco control legislation in the context of a largely state-owned industry, and discusses their implications for the policy process. Methods Several qualitative methods were employed for the study including: literature review and documentary analysis; key informant interview; focus groups discussion; and key stakeholders survey. Findings The Ministry of Health, Ministry of Trade and Industry, and Ministry of Finance are key players in the tobacco control policy and legislation, representing competing bureaucratic interests over health, macro-economy and revenue. High-ranking officials, including the Communist Party and National Assembly members, take a rather relaxed position reflecting the low political stakes placed on tobacco issues. The state-owned tobacco industry is regarded as an important contributor to the government revenue and gross domestic product, and the relative weight on health and socioeconomic issues placed by stakeholders determine their positions on tobacco control. Overall, short-term economic interests have more immediate influence in setting policy directions, with the consequences of health gains perceived as relegated to a distant future. This was reflected in the position of tobacco control advocates, including MOH, that presented with reluctance in insisting on some tobacco control strategies revealing a mixture attitude of concessions to the socioeconomic uncertainties and a sense of bargaining to win the strategies that are more likely to be accepted. Conclusion The state-ownership of tobacco industry poses a major paradox within the government that benefits from manufacturing of tobacco products and is also responsible for controlling tobacco consumption.

We examine current perceptions and constraints surrounding condom use among young adults in the Philippines to garner a deeper contextual understanding of this aspect of HIV prevention within Filipino society. Through thematic analysis of focus group data, we found three broad themes, all of which included societal and individual barriers to using condoms. The findings may provide insight for similar settings that have strong religious influences on society. To strengthen HIV prevention efforts in such settings, we suggest that the development of strategies to address these constraints in the cultural setting and promote sexual health of young adults is essential.

Abstract: Although transgender women have been included in HIV prevention pre-exposure prophylaxis studies, no pre-exposure prophylaxis study has focused exclusively on transgender persons. Drawing on the cardinal principles of ethics espoused in the Belmont Report, this work highlights, among other issues, that (1) the principle of Justice requires the HIV prevention field to focus exclusively on transgender persons, (2) the disclosure of potential study-related risks to study participants demonstrates Respect for Persons, and (3) devising risk mitigation plans, optimizing a proposed study's standard of care, and the provision of ancillary care satisfy the principle of Beneficence.
