Purpose of review Young women in sub-Saharan Africa bear a disproportionate HIV burden. They urgently require new HIV prevention approaches that women can use. This review provides an overview of the use of antiretrovirals for HIV pre-exposure prophylaxis (PrEP), highlighting some of the challenges with this technology and explores the potential role of monoclonal antibodies (mAbs) for HIV prevention in women. Recent findings Recent findings on the initial steps in viral entry and establishment of a productive local infectious nidus in the vaginal epithelium has provided important clues for HIV prevention in the female genital tract. Topical and oral formulations of antiretroviral drugs have been shown to prevent HIV infection in women with varying levels of success, depending principally on adherence. Further, a number of new broad and potent mAbs have been isolated over the last 5 years. Non-human primate studies demonstrate that broadly neutralizing HIV mAbs can protect rhesus macaques from SHIV infection. These findings have created newfound enthusiasm for passive immunization as a potential prevention strategy for women. Summary If potent broadly neutralising mAbs are effective in preventing HIV infection in women, it could fill an important gap in HIV prevention technologies for young women, especially in Africa.

Family Wellness, Not HIV Prevention

HIV exceptionalism (and disease-specific programs generally) garner both unbalanced funding and the most talented personnel, distorting local health priorities. In support of HIV exceptionalism, the successful mobilization of significant global health sector resources was not possible prior to HIV. Both sides of the debate have merits; rather than perpetuating polarization, we suggest that sustained improvements in global health require creating a prevention infrastructure to meet multiple health challenges experienced by local communities. We propose four fundamental shifts in HIV and disease prevention: (1) horizontally integrating prevention at one site locally, with priorities tailored to local health challenges and managed by local community leaders; (2) using a family wellness metaphor for services, not disease prevention; (3) implementing evidence-based prevention programs (EBPP) based on common principles, factors, and processes, rather than replication of specific programs; and (4) utilizing the expertise of private enterprise to re-design EBPP into highly attractive, engaging, and accessible experiences.

Opportunity Knocks: HIV Prevention in Primary Care.

PubMed

Thrun, Mark W

2014-06-01

Expansions in health care coverage, a comprehensive framework for HIV prevention and care, electronic medical records, and novel HIV prevention modalities create a current opportunity to change the trajectory of the HIV epidemic in the United States. HIV is increasingly disproportionately found in populations historically at higher risk, including gay men and other men who have sex with men, transgender women, injection drug users, and persons of color. This underscores the need for providers to identify persons at higher risk for HIV and assure the provision of screening and prevention services. In turn, universal screening for HIV-testing every adolescent and adult at least once in their lifetime-will increasingly be necessary to find the infrequent cases of HIV in lower risk populations. In both these domains, primary care providers will play a unique role in complementing traditional providers of HIV prevention and care services by increasing the proportion of their patients who have been screened for HIV, opening dialogues around sexual health, including asking about sexual orientation and gender identity, and prescribing antivirals as pre- and postexposure prophylaxis for their non-HIV-infected patients. Primary care providers must understand and embrace their importance along the HIV prevention and care continuum.

Trauma-Informed HIV Prevention and Treatment.

The high prevalence of trauma and its negative impact on health and health-promoting behaviors underscore the need for multi-level interventions to address trauma and its associated sequelae to improve physical and mental well-being in both HIV-infected and HIV-uninfected populations. Growing global awareness of the intersection of trauma and HIV has resulted in development and testing of interventions to address trauma in the context of HIV treatment and HIV prevention in the USA and globally. Despite increasing recognition of the widespread nature of trauma and the importance of trauma to HIV transmission around the globe, several gaps remain. Through a survey of the literature, we identified eight studies (published in the past 5 years) describing interventions to address the effects of trauma on HIV-related outcomes. In particular, this study focused on the levels of intervention, populations the interventions were designed to benefit, and types of trauma addressed in the interventions in the context of both HIV prevention and treatment. Remarkably absent from the HIV prevention, interventions reviewed were interventions designed to address violence experienced by men or transgender individuals, in the USA or globally. Given the pervasive nature of trauma experienced generally, but especially among individuals at heightened risk for HIV, future HIV prevention interventions universally should consider becoming trauma-informed. Widespread acknowledgement of the pervasive impact of gender-based violence on HIV outcomes among women has led to multiple calls for trauma-informed care (TIC) approaches to improve the effectiveness of HIV services for HIV-infected women. TIC approaches may be relevant for and should also be tested among men and all groups with high co-occurring epidemics of HIV and trauma (e.g., men who have sex with men (MSM), transgendered populations, injection drug users, sex workers), regardless of type of trauma experience.

Activation of Latent HIV Using Drug-loaded Nanoparticles

NASA Astrophysics Data System (ADS)

Kovochich, Michael

Antiretroviral therapy is currently only capable of controlling human immunodeficiency virus (HIV) replication, rather than completely eradicating virus from patients. This is due in part to the establishment of a latent virus reservoir in resting CD4+ T-cells, which persists even in the presence of highly active antiretroviral therapy (HAART). It is thought that forced activation of latently infected cells could induce virus production, allowing targeting of the cell by the immune response. A variety of molecules are able to stimulate HIV from latency. However, no tested purging strategy has proven capable of eliminating the infection completely or preventing viral rebound if therapy is stopped. Hence, novel latency activation approaches are required. Nanoparticles can offer several advantages over more traditional drug delivery methods, including improved drug solubility, stability, and the ability to simultaneously target multiple different molecules to particular cell or tissue types. Here we describe the development of a novel lipid nanoparticle with the protein kinase C activator bryostatin-2 incorporated (LNP-Bry). These particles can target, activate primary human CD4+ T-cells, and stimulate latent virus production from human T-cell lines in vitro and from latently infected cells in a humanized mouse model ex vivo. This activation was synergistically enhanced by the histone deacetylase inhibitor (HDACi) sodium butyrate. Furthermore, LNP-Bry can also be loaded with the protease inhibitor nelfinavir (LNP-Bry-Nel), producing a particle capable of both activating latent virus and inhibiting viral spread. LNP-Bry was further tested for its in vivo biodistribution in both wild type mice (C57 black 6), as well as humanized mice (SCID-hu Thy/Liv, and bone marrow-liver-thymus [BLT]). LNP-Bry accumulated in the spleen and induced the early activation marker CD69 in wild type mice. Taken together, these data demonstrate the ability of nanotechnological approaches to

Biomedical Approaches to HIV Prevention in Women.

Effective HIV prevention techniques for women are of critical importance, as nearly half of all HIV infections globally are in women. This article reviews the recent literature on biomedical approaches to HIV prevention in women. In trials in which women were adherent to oral pre-exposure prophylaxis (PrEP), PrEP was equally efficacious in men and women. However, in studies of oral PrEP exclusively in women, adherence was low, and it was not efficacious. In trials of topical PrEP, including vaginal tenofovir gel and the monthly dapivirine ring, efficacy was also dependent upon adherence. Treatment as prevention (TasP) is a very effective HIV prevention strategy, though limited in that it is not controlled by the HIV-uninfected partner. Adherence is an important factor in the efficacy of biomedical interventions for HIV prevention in women; continued research is needed to identify the most efficacious and acceptable agents for women. Oral PrEP is currently recommended for the following groups of HIV-negative women: heterosexual women in ongoing sexual relationships with a partner infected with or at substantial risk of HIV infection and women who inject drugs and share injection or drug preparation equipment.

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

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

Human immunodeficiency virus (HIV) infection and Mycobacterium tuberculosis (TB) are responsible for two of the major global human infectious diseases that result in significant morbidity, mortality and socioeconomic impact. Furthermore, severity and disease prevention of both infections is enhanced by co-infection. Parallel limitations also exist in access to effective drug therapy and the emergence of resistance. Furthermore, drug-drug interactions have proven problematic during treatment of co-incident HIV and TB infections. Thus, improvements in drug access and simplified treatment regimens are needed immediately. One of the key host cells infected by both HIV and TB is the mononuclear phagocyte (MP; monocyte, macrophage and dendritic cell). Therefore, we hypothesized that one way this can be achieved is through drug-targeting by a nanoformulated drug that ideally would be active against both HIV and TB. Accordingly, we validated macrophage targeted long acting (sustained drug release) gallium (Ga) nanoformulation against HIV-mycobacterium co-infection. The multi-targeted Ga nanoparticle agent inhibited growth of both HIV and TB in the macrophage. The Ga nanoparticles reduced the growth of mycobacterium and HIV for up to 15 days following single drug loading. These results provide a potential new approach to treat HIV-TB co-infection that could eventually lead to improved clinical outcomes. PMID:25744727

Accurate methods for estimating HIV incidence from cross-sectional samples would have great utility in prevention research. This report describes recent improvements in cross-sectional methods that significantly improve their accuracy. These improvements are based on the use of multiple biomarkers to identify recent HIV infections. These multi-assay algorithms (MAAs) use assays in a hierarchical approach for testing that minimizes the effort and cost of incidence estimation. These MAAs do not require mathematical adjustments for accurate estimation of the incidence rates in study populations in the year prior to sample collection. MAAs provide a practical, accurate, and cost-effective approach for cross-sectional HIV incidence estimation that can be used for HIV prevention research and global epidemic monitoring.

Highly active antiretroviral (ARV) therapy (HAART) for chronic suppression of HIV replication has revolutionized the treatment of HIV/AIDS. HAART is no panacea; treatments must be maintained for life. Although great progress has been made in ARV therapy, HIV continues to replicate in anatomical and intracellular sites where ARV drugs have restricted access. Nanotechnology has been considered a platform to circumvent some of the challenges in HIV/AIDS treatment. Dispersion polymerization was used to fabricate two types (PMM and ECA) of polymeric nanoparticles, and each was successfully loaded with four ARV drugs (zidovudine, lamivudine, nevirapine, and raltegravir), followed by physicochemical characterization: scanning electron microscope, particle size, zeta potential, drug loading, and in vitro availability. These nanoparticles efficiently inhibited HIV-1 infection in CEM T cells and peripheral blood mononuclear cells; they hold promise for the treatment of HIV/AIDS. The ARV-loaded nanoparticles with polyethylene glycol on the corona may facilitate tethering ligands for targeting specific receptors expressed on the cells of HIV reservoirs. PMID:27013886

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

The development of antiretroviral (ARV)-based prevention products has the potential to substantially change the HIV prevention landscape; yet, little is known about how appealing these products will be outside of clinical trials, as compared with the existing options. We conducted a discrete choice experiment (DCE) to measure preferences for 5 new products among 4 important populations in the HIV response: adult men and women in the general population (aged 18 to 49 y), adolescent girls (aged 16 to 17 y), and self-identifying female sex workers (aged 18 to 49 y). We interviewed 661 self-reported HIV-negative participants in peri-urban South Africa, who were asked to choose between 3 unique, hypothetical products over 10 choice sets. Data were analyzed using multinomial, latent class and mixed multinomial logit models. HIV protection was the most important attribute to respondents; however, results indicate significant demand among all groups for multipurpose prevention products that offer protection from HIV infection, other STIs, and unwanted pregnancy. All groups demonstrated a strong preference for long-lasting injectable products. There was substantial heterogeneity in preferences within and across population groups. Hypothetical DCE data may not mirror real-world choices, and products will have more attributes in reality than represented in choice tasks. Background data on participants, including sensitive areas of HIV status and condom use, was self-reported. These results suggest that stimulating demand for new HIV prevention products may require a more a nuanced approach than simply developing highly effective products. No single product is likely to be equally attractive or acceptable across different groups. This study strengthens the call for effective and attractive multipurpose prevention products to be deployed as part of a comprehensive combination prevention strategy.

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

2010-01-01

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.

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

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.

Gender-based violence and HIV: relevance for HIV prevention in hyperendemic countries of southern Africa.

PubMed

Andersson, Neil; Cockcroft, Anne; Shea, Bev

2008-12-01

Gender-based violence (GBV) is common in southern Africa. Here we use GBV to include sexual and non-sexual physical violence, emotional abuse, and forms of child sexual abuse. A sizeable literature now links GBV and HIV infection.Sexual violence can lead to HIV infection directly, as trauma increases the risk of transmission. More importantly, GBV increases HIV risk indirectly. Victims of childhood sexual abuse are more likely to be HIV positive, and to have high risk behaviours.GBV perpetrators are at risk of HIV infection, as their victims have often been victimised before and have a high risk of infection. Including perpetrators and victims, perhaps one third of the southern African population is involved in the GBV-HIV dynamic.A randomised controlled trial of income enhancement and gender training reduced GBV and HIV risk behaviours, and a trial of a learning programme reported a non-significant reduction in HIV incidence and reduction of male risk behaviours (primary prevention). Interventions among survivors of GBV can reduce their HIV risk (secondary prevention). Various strategies can reduce spread of HIV from infected GBV survivors (tertiary prevention). Dealing with GBV could have an important effect on the HIV epidemic.A policy shift is necessary. HIV prevention policy should recognise the direct and indirect implications of GBV for HIV prevention, the importance of perpetrator dynamics, and that reduction of GBV should be part of HIV prevention programmes. Effective interventions are likely to include a structural component, and a GBV awareness component.

Induction of humoral responses to HIV at mucosal compartments without inflammation is important for vaccine design. We developed charged wax nanoparticles that efficiently adsorb protein antigens and are internalized by DC in the absence of inflammation. HIV-gp140-adsorbed nanoparticles induced stronger in vitro T-cell proliferation responses than antigen alone. Such responses were greatly enhanced when antigen was co-adsorbed with TLR ligands. Immunogenicity studies in mice showed that intradermal vaccination with HIV-gp140 antigen-adsorbed nanoparticles induced high levels of specific IgG. Importantly, intranasal immunization with HIV-gp140-adsorbed nanoparticles greatly enhanced serum and vaginal IgG and IgA responses. Our results show that HIV-gp140-carrying wax nanoparticles can induce strong cellular/humoral immune responses without inflammation and may be of potential use as effective mucosal adjuvants for HIV vaccine candidates.

Behavioral change interventions using peer group leaders are effective and widely used, but few studies have examined how being a peer group leader affects the leaders. This study describes how participants felt being a peer group leader affected their lives. This descriptive qualitative study interviewed 18 experienced peer group leaders who had conducted a multisession human immunodeficiency virus (HIV) prevention peer group intervention in rural Malawi. We used inductive content analysis and comparisons within and between cases. Three major themes were identified. All leaders said they experienced personal changes in their knowledge, attitudes, or HIV prevention behaviors. They described interacting with family, neighbors, and friends, and speaking at church or community meetings, to discuss HIV prevention issues. They increased their self-efficacy to engage others in sensitive HIV prevention issues, developed a self-identity as a change agent, and came to be recognized in their community as trustworthy advisors about HIV and acquired immunodeficiency syndrome. These three themes, taken together, form the meta-theme of psychological empowerment. Being a peer group leader empowered the leaders as change agents for HIV prevention and had impacts in the community after the intervention ended, potentially increasing the long-term effectiveness and cost effectiveness of peer group interventions. Healthcare workers and community volunteers who led HIV prevention sessions continued HIV prevention activities in the community and workplace after the program ended. Training health workers as volunteer HIV prevention leaders offers a strategy to bring HIV prevention to limited-resource settings, despite health worker shortages. © 2013 Sigma Theta Tau International.

This article aimed to examine changes in the HIV prevention capacity of HIV prevention program managers who completed the Institute for HIV Prevention Leadership ("Institute") between 2002 and 2004, and who worked in community-based organizations that primarily served African Americans. Participants completed a survey at three points in time, in which they rated the frequency with which they conducted activities related to HIV prevention practice. Participants also rated their confidence in performing activities. Repeated measures ANOVA was conducted to detect differences at three time points (baseline, immediate posttest, and 6 months posttest). A significant overall positive trend was found in the frequency and confidence of participants to perform specific HIV prevention practices and an overall positive trend in the frequency of processes that support HIV prevention practice. Investment in long-term, intensive, capacity-building programs like the Institute is critical to address the increasing incidence of HIV in many African American communities.

Black women bear a disproportionate burden of HIV/AIDS in North America. The purpose of this investigation was to explore Black Canadian women's perspectives on HIV risk and prevention. Four 90-minute focus groups (n=26) and six key informant interviews were conducted in Toronto with Black women of African and Caribbean descent and low socioeconomic status. Data analysis revealed a number of potent barriers to existing HIV preventive interventions: stigma, cultural disconnections, lack of engagement of Black religious institutions, and multiple intersecting forms of discrimination. Recommended HIV prevention opportunities included the Black church, mainstreaming, health care providers, and ethno-specific agencies. HIV prevention strategies for North American Black women, rather than focusing on HIV and individual risk behaviors, may benefit from a primary focus on social and structural factors (e.g., promoting gender equality, economic opportunity, women-controlled prevention technologies and combating racism in health care) thereby integrating HIV prevention into the larger context of community health and survival.

Antiretroviral therapy as HIV prevention: status and prospects.

PubMed

Mayer, Kenneth H; Venkatesh, Kartik K

2010-10-01

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.

To estimate the optimal allocation of Centers for Disease Control and Prevention (CDC) HIV prevention funds for health departments in 52 jurisdictions, incorporating Health Resources and Services Administration (HRSA) Ryan White HIV/AIDS Program funds, to improve outcomes along the HIV care continuum and prevent infections. Using surveillance data from 2010 to 2012 and budgetary data from 2012, we divided the 52 health departments into 5 groups varying by number of persons living with diagnosed HIV (PLWDH), median annual CDC HIV prevention budget, and median annual HRSA expenditures supporting linkage to care, retention in care, and adherence to antiretroviral therapy. Using an optimization and a Bernoulli process model, we solved for the optimal CDC prevention budget allocation for each health department group. The optimal allocation distributed the funds across prevention interventions and populations at risk for HIV to prevent the greatest number of new HIV cases annually. Both the HIV prevention interventions funded by the optimal allocation of CDC HIV prevention funds and the proportions of the budget allocated were similar across health department groups, particularly those representing the large majority of PLWDH. Consistently funded interventions included testing, partner services and linkage to care and interventions for men who have sex with men (MSM). Sensitivity analyses showed that the optimal allocation shifted when there were differences in transmission category proportions and progress along the HIV care continuum. The robustness of the results suggests that most health departments can use these analyses to guide the investment of CDC HIV prevention funds into strategies to prevent the most new cases of HIV.

Linkage of HIV-negative youth to prevention services is increasingly important with the development of effective pre-exposure prophylaxis that complements behavioral and other prevention-focused interventions. However, effective infrastructure for delivery of prevention services does not exist, leaving many programs to address HIV prevention without data to guide program development/implementation. The objective of this study was to provide a qualitative description of barriers and facilitators of linkage to prevention services among high-risk, HIV-negative youth. Thematic analysis of structured interviews with staff implementing linkage to prevention services programs for youth aged 12-24 years. Twelve adolescent medicine HIV primary care programs as part of larger testing research program focused on young sexual minority men of color. The study included staff implementing linkage to prevention services programs along with community-based HIV testing programs. The main outcomes of the study were key barriers/facilitators to linkage to prevention services. Eight themes summarized perspectives on linkage to prevention services: (1) relationships with community partners, (2) trust between providers and youth, (3) youth capacity to navigate prevention services, (4) pre-exposure prophylaxis specific issues, (5) privacy issues, (6) gaps in health records preventing tailored services, (7) confidentiality of care for youth accessing services through parents'/caretakers' insurance, and (8) need for health-care institutions to keep pace with models that prioritize HIV prevention among at-risk youth. Themes are discussed in the context of factors that facilitated/challenged linkage to prevention services. Several evidence-based HIV prevention tools are available; infrastructures for coordinated service delivery to high-risk youth have not been developed. Implementation of such infrastructures requires attention to community-, provider-, and youth-related issues. Copyright �

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.

WHO reports 36.7 million people are living with Human Immunodeficiency Virus (HIV) worldwide by 2016 with about 1.8 million new infections each year. It will be a specific health problem for the world in both developed and developing countries so it is necessary strategies to reduce HIV transmission to the community. HIV transmission in people with risk factors is largely determined by the amount of virus in the blood of people who are the source of infection. Antiretroviral (ARV) therapy has long been used in HIV patients, which serves to suppress viral replication so that the patient’s immunity increases; opportunistic infections are resolved and prolong the lifespan and lower transmission rates. In the HIV Prevention Trials Network (HPTN) study 052 there was a 96% reduction in transmission in earlier antiretroviral. ARV is also used in the prevention of transmission in people exposed to HIV virus that is Postexposure Prophylaxis as well as in people at risk before exposure (Pre-exposure Prophylaxis). Three prevention strategies with the provision of ARV is expected to be guided as a means of prevention of transmission in addition to behavioral changes has long been declared since the beginning of the HIV epidemic.

Induction of humoral responses to HIV at mucosal compartments without inflammation is important for vaccine design. We developed charged wax nanoparticles that efficiently adsorb protein antigens and are internalized by DC in the absence of inflammation. HIV-gp140-adsorbed nanoparticles induced stronger in vitro T-cell proliferation responses than antigen alone. Such responses were greatly enhanced when antigen was co-adsorbed with TLR ligands. Immunogenicity studies in mice showed that intradermal vaccination with HIV-gp140 antigen-adsorbed nanoparticles induced high levels of specific IgG. Importantly, intranasal immunization with HIV-gp140-adsorbed nanoparticles greatly enhanced serum and vaginal IgG and IgA responses. Our results show that HIV-gp140-carrying wax nanoparticles can induce strong cellular/humoral immune responses without inflammation and may be of potential use as effective mucosal adjuvants for HIV vaccine candidates.

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-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 determinationmore » 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

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.

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. 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. 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. 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.

RNA interference (RNAi)-mediated gene silencing offers a novel treatment and prevention strategy for human immunodeficiency virus (HIV) infection. HIV was found to infect and replicate in human brain cells and can cause neuroinfections and neurological deterioration. We designed dual-antibody-modified chitosan/small interfering RNA (siRNA) nanoparticles to deliver siRNA across the blood-brain barrier (BBB) targeting HIV-infected brain astrocytes as a strategy for inhibiting HIV replication. We hypothesized that transferrin antibody and bradykinin B2 antibody could specifically bind to the transferrin receptor (TfR) and bradykinin B2 receptor (B2R), respectively, and deliver siRNA across the BBB into astrocytes as potential targeting ligands. In this study, chitosan nanoparticles (CS-NPs) were prepared by a complex coacervation method in the presence of siRNA, and antibody was chemically conjugated to the nanoparticles. The antibody-modified chitosan nanoparticles (Ab-CS-NPs) were spherical in shape, with an average particle size of 235.7 ± 10.2 nm and a zeta potential of 22.88 ± 1.78 mV. The therapeutic potential of the nanoparticles was evaluated based on their cellular uptake and gene silencing efficiency. Cellular accumulation and gene silencing efficiency of Ab-CS-NPs in astrocytes were significantly improved compared to non-modified CS-NPs and single-antibody-modified CS-NPs. These results suggest that the combination of anti-Tf antibody and anti-B2 antibody significantly increased the knockdown effect of siRNA-loaded nanoparticles. Thus, antibody-mediated dual-targeting nanoparticles are an efficient and promising delivery strategy for inhibiting HIV replication in astrocytes.

People living with human immunodeficiency virus (HIV)/AIDS (PLWH/A) and others affected have expressed that cultural differences between patients and providers can create barriers to care and prevention. These barriers are exacerbated in the case of vulnerable populations who are often marginalized by society. During the formative phase of a community-based participatory research (CBPR) process, the researchers' community advisory committee (CAC) and HIV stakeholders shared anecdotes of incongruencies between needs of HIV-vulnerable populations and expertise of local providers. In response, researchers worked with the CAC to develop survey questions intended for providers of HIV prevention services in a region afflicted with some of the highest HIV prevalence rates in the country. The objective of this study was to identify and validate HIV stakeholders' perceptions about challenges to provision of HIV services through a sequential mixed methods study design. Thirty HIV prevention organizations (HPOs) were identified as local leaders in HIV prevention by community stakeholders and through community event attendance. Each HPO was invited to participate in an interviewer-assisted survey examining population-specific expertise and service for 15 HIV-vulnerable populations. Frequency analysis was used to compare HPOs' expertise relative to who they serve (n = 26). Although 13 of the HIV-vulnerable populations were served by more than 50% of the HPOs, only 2 of these 13 populations were served with high expertise by more than one half of the HPOs in the sample. These data give credence to the CAC's concern regarding misalliance between whom HPOs serve and with whom they have high expertise, a factor potentially influencing HIV outcomes among HIV-vulnerable populations.

We examined HIV-infected parents' conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. 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. 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. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents.

The Promise of Antiretrovirals for HIV Prevention

2013-01-01

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

Objective The goal of this research was to evaluate changes over time in the capacity of participants of the CDC/ASPH Institute for HIV Prevention Leadership (Institute), a capacity-building program for HIV prevention program managers in minority-based, community-based organizations, Capacity was defined as the application of new skills and knowledge to participants’ jobs and confidence in using those new skills and knowledge to strategically manage and apply “best practices” to their HIV prevention activities. Methods This is a longitudinal study involving measuring scholar capacity at three points in time; pre-Institute, post-Institute, and 6 months’ post-Institute. Only responses from participants who completed all three surveys are included in this final analysis of the data (N = 94). Results Results indicate that participants from 3 years of the institute (2002–2004) increased their capacity in HIV prevention programming and strategic planning and management. Significant changes were seen in the frequency and self-efficacy with which participants conduct several HIV prevention programming activities. Participants also reported conducting strategic planning activities at more appropriate intervals and were significantly more confident in conducting these activities. Conclusion The Institute has positively and significantly increased the capacity of participants to conduct more effective HIV prevention programs on a national level. PMID:17159470

HIV prevention cost-effectiveness: a systematic review

PubMed Central

2009-01-01

Background After more than 25 years, public health programs have not been able to sufficiently reduce the number of new HIV infections. Over 7,000 people become infected with HIV every day. Lack of convincing evidence of cost-effectiveness (CE) may be one of the reasons why implementation of effective programs is not occurring at sufficient scale. This paper identifies, summarizes and critiques the CE literature related to HIV-prevention interventions in low- and middle-income countries during 2005-2008. Methods Systematic identification of publications was conducted through several methods: electronic databases, internet search of international organizations and major funding/implementing agencies, and journal browsing. Inclusion criteria included: HIV prevention intervention, year for publication (2005-2008), setting (low- and middle-income countries), and CE estimation (empirical or modeling) using outcomes in terms of cost per HIV infection averted and/or cost per disability-adjusted life year (DALY) or quality-adjusted life year (QALY). Results We found 21 distinct studies analyzing the CE of HIV-prevention interventions published in the past four years (2005-2008). Seventeen CE studies analyzed biomedical interventions; only a few dealt with behavioral and environmental/structural interventions. Sixteen studies focused on sub-Saharan Africa, and only a handful on Asia, Latin America and Eastern Europe. Many HIV-prevention interventions are very cost effective in absolute terms (using costs per DALY averted), and also in country-specific relative terms (in cost per DALY measured as percentage of GDP per capita). Conclusion There are several types of interventions for which CE studies are still not available or insufficient, including surveillance, abstinence, school-based education, universal precautions, prevention for positives and most structural interventions. The sparse CE evidence available is not easily comparable; thus, not very useful for decision

Optimal investment in a portfolio of HIV prevention programs.

Zaric, G S; Brandeau, M L

2001-01-01

In this article, the authors determine the optimal allocation of HIV prevention funds and investigate the impact of different allocation methods on health outcomes. The authors present a resource allocation model that can be used to determine the allocation of HIV prevention funds that maximizes quality-adjusted life years (or life years) gained or HIV infections averted in a population over a specified time horizon. They apply the model to determine the allocation of a limited budget among 3 types of HIV prevention programs in a population of injection drug users and nonusers: needle exchange programs, methadone maintenance treatment, and condom availability programs. For each prevention program, the authors estimate a production function that relates the amount invested to the associated change in risky behavior. The authors determine the optimal allocation of funds for both objective functions for a high-prevalence population and a low-prevalence population. They also consider the allocation of funds under several common rules of thumb that are used to allocate HIV prevention resources. It is shown that simpler allocation methods (e.g., allocation based on HIV incidence or notions of equity among population groups) may lead to alloctions that do not yield the maximum health benefit. The optimal allocation of HIV prevention funds in a population depends on HIV prevalence and incidence, the objective function, the production functions for the prevention programs, and other factors. Consideration of cost, equity, and social and political norms may be important when allocating HIV prevention funds. The model presented in this article can help decision makers determine the health consequences of different allocations of funds.

Preventing HIV infection without targeting the virus: how reducing HIV target cells at the genital tract is a new approach to HIV prevention.

PubMed

Lajoie, Julie; Mwangi, Lucy; Fowke, Keith R

2017-09-12

For over three decades, HIV infection has had a tremendous impact on the lives of individuals and public health. Microbicides and vaccines studies have shown that immune activation at the genital tract is a risk factor for HIV infection. Furthermore, lower level of immune activation, or what we call immune quiescence, has been associated with a lower risk of HIV acquisition. This unique phenotype is observed in highly-exposed seronegative individuals from different populations including female sex workers from the Pumwani cohort in Nairobi, Kenya. Here, we review the link between immune activation and susceptibility to HIV infection. We also describe a new concept in prevention where, instead of targeting the virus, we modulate the host immune system to resist HIV infection. Mimicking the immune quiescence phenotype might become a new strategy in the toolbox of biomedical methods to prevent HIV infection. Clinical trial registration on clinicaltrial.gov: #NCT02079077.

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

HIV Treatment as Prevention: Natural Experiments Highlight Limits of Antiretroviral Treatment as HIV Prevention

PubMed Central

Wilson, David P.

2012-01-01

There is growing enthusiasm for increasing coverage of antiretroviral treatment among HIV-infected people for the purposes of preventing ongoing transmission. Treatment as prevention will face a number of barriers when implemented in real world populations, which will likely lead to the effectiveness of this strategy being lower than proposed by optimistic modelling scenarios or ideal clinical trial settings. Some settings, as part of their prevention and treatment strategies, have already attained rates of HIV testing and use of antiretroviral therapy—with high levels of viral suppression—that many countries would aspire to as targets for a treatment-as-prevention strategy. This review examines a number of these “natural experiments”, namely, British Columbia, San Francisco, France, and Australia, to provide commentary on whether treatment as prevention has worked in real world populations. This review suggests that the population-level impact of this strategy is likely to be considerably less than as inferred from ideal conditions. PMID:22807656

Long-acting rilpivirine for HIV prevention.

PubMed

Jackson, Akil; McGowan, Ian

2015-07-01

Long-acting injectable antiretroviral (ARV) formulations are being developed for the treatment and prevention of HIV infection. The purpose of this review is to summarize recent preclinical and clinical data on TMC278 (rilpivirine), a nonnucleoside reverse transcriptase inhibitor (NNRTI), that is being developed for both a treatment and prevention indication. Long-acting rilpivirine has demonstrated efficacy in preventing HIV acquisition in a humanized mouse model and has been found to be well tolerated and acceptable in several Phase I clinical trials. Pharmacokinetic data from Phase I studies suggest that 1200 mg of long-acting rilpivirine administered every 8 weeks would be associated with plasma and tissue levels of rilpivirine anticipated to be necessary for preventing HIV infection. This regimen is being evaluated in the HPTN-076 Phase II expanded safety study that will enroll women in South Africa, Zimbabwe, and the USA. The HPTN-076 study requires a 4-week run in with oral rilpivirine (25 mg capsules) before receiving 1200 mg of rilpivirine. It is not yet certain whether oral dosing will remain a prerequisite in future trials or post licensure. Long-acting rilpivirine shows promise as a candidate agent for HIV prevention. Preclinical efficacy has been demonstrated in a murine model. Phase I studies have shown good safety and efficacy, but breakthrough infection and resistance have been documented with lower doses of long-acting rilpivirine. Phase II development for a prevention indication is ongoing.

Persson, Asha; Brown, Graham; McDonald, Ann; Körner, Henrike

2014-06-01

In Australia, unlike much of the rest of the world, HIV transmission through heterosexual contact remains a relatively rare occurrence. In consequence, HIV-prevention efforts have been firmly focused on male-to-male sex as the most frequent source of HIV transmission. There are emerging signs that this epidemiological landscape may be shifting, which raises questions about current and future HIV prevention strategies. Over the past decade, national surveillance data have shown an increase in HIV notifications for which exposure to HIV was attributed to heterosexual contact. This paper offers an epidemiological and sociocultural picture of heterosexual HIV transmission in Australia. We outline recent trends in heterosexually acquired HIV and discuss specific factors that shape transmission and prevention among people at risk of HIV infection through heterosexual contact. To illustrate the contextual dynamics surrounding HIV in this diverse population, we detail two key examples: HIV among people from minority ethnic backgrounds in New South Wales; and overseas-acquired HIV among men in Western Australia. We argue that, despite their differences, there are significant commonalities across groups at risk of HIV infection through heterosexual contact, which not only provide opportunities for HIV prevention, but also call for a rethink of the dominant HIV response in Australia.

Chemoprophylaxis for HIV prevention: new opportunities and new questions.

Mayer, Kenneth H; Venkatesh, Kartik K

2010-12-01

Growing data suggest that antiretrovirals can be used as an effective means of HIV prevention. This article reviews the current status and future clinical prospects of utilizing antiretroviral chemoprophylaxis before and after high-risk HIV exposure to prevent HIV transmission. The discussion about using antiretrovirals as a means of primary HIV prevention has moved to the forefront of public health discourse because of a growing evidence base, the increased tolerability of the medications, the decreased cost, the ever-expanding formulary, and the limitations of other approaches.

HIV Prevention: Opportunities and Challenges.

PubMed

Marrazzo, Jeanne M

Preexposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)-based regimens has been shown to be effective in preventing acquisition of HIV infection, with protective efficacy being dependent on adherence to treatment. Data from the PROUD (Preexposure Option for Reducing HIV in the UK) and IPERGAY (Action to Prevent Risk Exposure By and For Gay Men) studies, the later of which employed event-driven PrEP, showed a high rate of protective efficacy of PrEP with TDF and emtricitabine among men who have sex with men. Data from the ASPIRE (A Study to Prevent Infection With a Ring for Extended Use) study of a dapivirine vaginal ring showed a moderate rate of protective efficacy among women older than 21 years. Ongoing investigations are examining long-acting PrEP modalities and combination PrEP and contraception products. This article summarizes a presentation by Jeanne M. Marrazzo, MD, MPH, at the IAS-USA continuing education program, Improving the Management of HIV Disease, held in Washington, DC, in April 2016.

Secondary HIV prevention among kothi-identified MSM in Chennai, India.

PubMed

Chakrapani, Venkatesan; Newman, Peter A; Shunmugam, Murali

2008-05-01

This study explored experiences and contexts of HIV risk and prevention among HIV-positive kothi-identified men in Chennai, India. In-depth, semi-structured interviews were conducted with 10 HIV-positive men and three service providers, recruited using purposive sampling. Interviews were audio-taped, transcribed in Tamil and translated into English. Data were analysed using a narrative thematic approach and constant comparative method. Misconceptions about HIV transmission; cultural taboos around discussing sexual behaviour and HIV; stigma related to same-sex behaviour; harassment; and the criminalization of consensual sex between men present formidable challenges to HIV prevention. Frank and open discussion about male-to-male sexual behaviour and living with HIV, which may support health and HIV prevention, may be dangerous in the context of pervasive risks due to stigmatization, violence and criminalization. Instead, culturally appropriate, multi-level interventions developed in collaboration with community stakeholders are needed to support HIV prevention among kothi-identified men in South India.

Insight into Jordanian thinking about HIV: knowledge of Jordanian men and women about HIV prevention.

2014-01-01

Research on HIV prevention programs for countries with large Muslim populations is scarce. HIV knowledge, attitudes, and beliefs were assessed in a convenience sample of 128 women and 88 men at two universities in Jordan with the goal of gaining insight into how to approach HIV risk behaviors. In general terms, 97% of participants had heard of AIDS and the majority understood the common methods of transmission. Misconceptions were common; most participants did not recognize condoms as an HIV prevention method. A sense of fatalism regarding the acquisition of HIV was common. In Jordan, challenges to HIV-prevention interventions includes misconceptions about HIV transmission, gender-related differences in the willingness to discuss sexual issues, and fatalism regarding the acquisition of HIV. Silence about sexual activity, particularly among women, was pervasive. Culturally tailored interventions are needed to decrease stigma and address gender inequalities that may contribute to increased risks of HIV in Jordan.

2014-05-01

Faith-based organizations (FBOs) have a long tradition of providing HIV/AIDS prevention and mitigation services in Africa. The overall response of FBOs, however, has been controversial, particularly in regard to HIV/AIDS prevention and FBO's rejection of condom use and promotion, which can conflict with and negatively influence national HIV/AIDS prevention response efforts. This article reports the findings from a study that explored the factors influencing the HIV/AIDS prevention policy process within faith-based non-governmental organizations (NGOs) of different faiths. These factors were examined within three faith-based NGOs in Dar es Salaam, Tanzania-a Catholic, Anglican and Muslim organization. The research used an exploratory, qualitative case-study approach, and employed a health policy analysis framework, examining the context, actor and process factors and how they interact to form content in terms of policy and its implementation within each organization. Three key factors were found to influence faith-based NGOs' HIV/AIDS prevention response in terms of both policy and its implementation: (1) the faith structure in which the organizations are a part, (2) the presence or absence of organizational policy and (3) the professional nature of the organizations and its actors. The interaction between these factors, and how actors negotiate between them, was found to shape the organizations' HIV/AIDS prevention response. This article reports on these factors and analyses the different HIV/AIDS prevention responses found within each organization. By understanding the factors that influence faith-based NGOs' HIV/AIDS prevention policy process, the overall faith-based response to HIV/AIDS, and how it corresponds to national response efforts, is better understood. It is hoped that by doing so the government will be better able to identify how to best work with FBOs to meet national HIV/AIDS prevention targets, improving the overall role of FBOs in the fight against

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.

Adolescent lives matter: preventing HIV in adolescents

Pettifor, Audrey; Stoner, Marie; Pike, Carey; Bekker, Linda-Gail

2018-01-01

Purpose of review Many of the almost 2 million HIV infections that occurred globally in the last year occurred among adolescents and young people, particularly those from East and Southern Africa and within key populations. Global HIV epidemic control will require that new infections among these youth populations be curtailed. This review examines the most effective prevention approaches to reach these adolescent populations in the next 5 years. Recent findings Adolescents are in transition and are developmentally unique. They have specific needs and challenges, which if not addressed will result in less than successful interventions. Tailored, layered, combination prevention packages that take into account specific adolescent needs and involve biomedical, behavioural and structural components are recommended. These packages should be designed for and with the meaningful input of adolescents, and involve their peers in their implementation and execution. Where possible, age-appropriate health and social interventions that go beyond HIV should be bundled and offered in a variety of community-based venues that are already acceptable to and frequented by adolescents. Summary It is urgent that we reach adolescents globally with the most effective HIV prevention approaches. HIV prevention investment in this population has immediate and longer-term benefits.

Digital gaming for HIV prevention with young adolescents.

PubMed

Enah, Comfort; Moneyham, Linda; Vance, David E; Childs, Gwendolyn

2013-01-01

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.

Antibody-Based Preventive and Therapeutic Strategies Against HIV.

PubMed

Fabra-Garcia, Amanda; Beltran, Carolina; Sanchez-Merino, Victor; Yuste, Eloisa

2016-01-01

Over the years, numerous studies have been carried out demonstrating the role of antibodies in HIV control leading to the development of antibody-based therapeutic and prophylactic strategies. The objective of this review is to provide updated information on the role of antibodies in the prevention and control of HIV infection and the strategies against HIV that have been designed based on this information. Passive transfer of anti-HIV antibodies in animal models has proven the efficacy of certain antibodies in the prevention and treatment of infection. The capacity of antibodies to control the virus was first attributed to their neutralizing capacity. However, we now know that there are other Fc-mediated antibody activities associated with virus protection. When it comes to better understanding protection against HIV, we ought to pay particular attention to mucosal immune responses. The evidence accumulated so far indicates that an effective vaccine against HIV should generate both mucosal IgAs and systemic IgGs. Due to the problematic induction of protective anti-HIV antibodies, several groups have developed alternative approaches based on antibody delivery via gene therapy vectors. Experiments in animal models with these vectors have shown impressive protection levels and this strategy is now being clinically trialed. Taking into account all the information included in this review, it seems evident that anti-HIV-1 antibodies play an important role in virus control and prevention. This review aims to give an overview of the strategies used and the advances in antibody-based preventive and therapeutic strategies against HIV-1.

Community-based organizations (CBOs) are critical to delivery of effective HIV prevention because of their reach to key populations. This online survey of a national sample of CBOs assessed their awareness of, interest in, and resources needed to provide nonoccupational postexposure prophylaxis (nPEP), preexposure prophylaxis (PrEP), and HIV treatment as prevention (TasP). One hundred seventy-five CBOs participated: 87 clinical and 88 nonclinical CBOs. For nPEP, PrEP, and TasP, program managers reported that awareness was high (94%, 90%, 85%), meeting current client need was low (20%, 13%, 18%), and the likelihood of increasing their current provision with additional resources was somewhat high (62%, 64%, 62%). Clinical CBOs were more prepared to support expansion of these biomedical interventions than nonclinical CBOs. Meeting the information, training, and resource needs of CBOs is critical for effective collaboration to reduce the number of new HIV infections through expanded delivery of PrEP, nPEP, and TasP.

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.

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.

The Use of Technology to Advance HIV Prevention for Couples.

Mitchell, Jason W

2015-12-01

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 couple-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 that 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 couple-focused HIV-preventive interventions.

HIV prevention in prisons and jails: obstacles and opportunities.

Polonsky, S; Kerr, S; Harris, B; Gaiter, J; Fichtner, R R; Kennedy, M G

1994-01-01

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.

Clinical Trial Design for HIV Prevention Research: Determining Standards of Prevention.

Dawson, Liza; Zwerski, Sheryl

2015-06-01

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.

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

Dolan, Kate; Larney, Sarah

2010-12-01

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. 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. 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). 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.

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).

Self-testing for HIV: a new option for HIV prevention?

Self-testing has the potential to be an innovative component to community-wide HIV-prevention strategies. This testing method could serve populations who do not have access to standard voluntary counselling and testing services or because of privacy concerns, stigma, transport costs, or other barriers do not use facility-based, standard HIV testing. This paper reviews recent research on the acceptability, feasibility, and cost of rapid testing and home-specimen collection for HIV, and suggests that self-testing may be another important strategy for diagnosing HIV infection. Several research questions are posed that should be answered before self-testing is realised.

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.

HIV Prevention Among Transgender Populations: Knowledge Gaps and Evidence for Action.

The purpose of this review is to summarize the available evidence-based HIV prevention interventions tailored for transgender people. A limited number of evidence-based HIV prevention interventions have been tested with transgender populations. Most existing interventions target behavior change among transgender women, with only one HIV prevention program evaluated for transgender men. Studies addressing biomedical interventions for transgender women are ongoing. Few interventions address social and structural barriers to HIV prevention, such as stigma, discrimination, and poverty. Evidence-based multi-level interventions that address the structural, biomedical, and behavioral risks for HIV among transgender populations, including transgender men, are needed to address disparities in HIV prevalence. Future research should address not only pre-exposure prophylaxis uptake and condom use but also structural barriers that limit access to these prevention strategies.

Nanotechnology and HIV: potential applications for treatment and prevention.

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. © 2010 John Wiley & Sons, Inc.

Buchbinder, Susan P; Liu, Albert Y

2016-01-01

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.

Approaches to Preventative and Therapeutic HIV vaccines

Novel strategies are being researched to discover vaccines to prevent and treat HIV-1. Nonefficacious preventative vaccine approaches include bivalent recombinant gp120 alone, HIV gene insertion into an Adenovirus 5 (Ad5) virus vector and the DNA prime/Ad5 boost vaccine regimen. However, the ALVAC-HIV prime/AIDSVAX® B/E gp120 boost regimen showed 31.2% efficacy at 3.5 years, and is being investigated as clade C constructs with an additional boost. Likewise, although multiple therapeutic vaccines have failed in the past, in a non-placebo controlled trial, a Tat vaccine demonstrated immune cell restoration, reduction of immune activation, and reduced HIV-1 DNA viral load. Monoclonal antibodies for passive immunization or treatment show promise, with VRC01 entering advanced clinical trials. PMID:26985884

To reduce current HIV disparities among African American youth, it is imperative to find effective ways to extend the reach of evidence-based HIV prevention. One promising community resource to support this effort is faith-based organizations (FBOs), a credible and respected resource in the African American community. This paper describes the experiences, perceptions, and challenges that African American FBOs and faith leaders face in engaging in adolescent HIV prevention and highlights facilitators and barriers to implementing HIV prevention in African American FBOs. The findings suggest that African American FBOs and faith-based leaders are uniquely positioned to be instrumental resources in reducing African American youth HIV disparities.

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

Structural factors in HIV prevention: concepts, examples, and implications for research.

PubMed

Sumartojo, E

2000-06-01

HIV-prevention behavior is affected by the environment as well as by characteristics of individuals at risk. HIV-related structural factors are defined as barriers to, or facilitators of, an individual's HIV prevention behaviors; they may relate to economic, social, policy, organizational or other aspects of the environment. A relatively small number of intervention studies demonstrates the potential of structural interventions to increase HIV prevention in the United States and internationally. The promise of structural interventions has also been shown in studies of interventions to prevent disease or promote public health in areas other than HIV. Frameworks help define and exemplify structural barriers and facilitators for HIV prevention. One framework developed at Centers for Disease Control and Prevention gives examples of structural facilitators in terms of the economic resources, policy supports, societal attitudes, and organizational structures and functions associated with governments, service organizations, businesses, workforce organizations, faith communities, justice systems, media organizations, educational systems, and healthcare systems. Frameworks should assist researchers and health officials to identify important areas for structural research and programming. A structural approach is timely and innovative. Despite limitations, including the challenge of a new perspective on prevention and the difficulty of evaluating their effects, researchers and public health officials are urged to pursue structural interventions to prevent HIV.

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.

HIV healthcare services in the USA are made available through a complex funding and delivery system. We present perspectives of HIV agencies on improvements that could lead to an ideal system of HIV prevention, treatment and care. We conducted semi-structured interviews with representatives from 21 HIV agencies offering diverse services in Baltimore, MD. Thematic analysis revealed six key themes: (1) Focusing on HIV prevention, (2) Establishing common entry-points for services, (3) Improving information availability, (4) Streamlining funding streams, (5) Removing competitiveness and (6) Building trust. We recommend that in addition to addressing operational issues regarding service delivery and patient care, initiatives to improve HIV service systems should address underlying social issues such as building trust.

Shared Communities, Structural Contexts, and HIV Risk: Prioritizing the HIV Risk and Prevention Needs of Black Heterosexual Men

Raj, Anita

2012-01-01

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.

Microbicides represent a potential intervention strategy for preventing HIV transmission. Vaginal microbicides would meet the need for a discreet method that women could use to protect themselves against HIV. Although early-generation microbicides failed to demonstrate efficacy, newer candidates are based on more potent antiretroviral (ARV) products. Positive data from the CAPRISA 004 trial of tenofovir gel support use in women and represent a turning point for the field. This article reviews current progress in development of ARV-based microbicides. We discuss the consensus on selection criteria, the potential for drug resistance, rationale for drug combinations, and the use of pharmacokinetic (PK)/pharmacodynamic (PD) assessment in product development. The urgent need for continued progress in development of formulations for sustained delivery is emphasized. Finally, as the boundaries between different prevention technologies become increasingly blurred, consideration is given to the potential synergy of diverse approaches across the prevention landscape.

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.

In a pilot study, young people in slums in Kampala, Uganda received an HIV prevention program (Street Smart) and were randomized to receive vocational training immediately (Immediate) or four months later (Delayed). Youth were monitored at recruitment, 4 months (85% retention), and 24 months (74% retention). Employment increased dramatically: Only 48% had ever been employed at recruitment, 86% were employed from months 21 to 24 post recruitment. Over two years, decreases were recorded in the number of sexual partners, mental health symptoms, delinquent acts, and drug use; condom use increased. Providing employment in low income countries, in conjunction with HIV prevention, may provide sustained support to young people to prevent HIV acquisition. PMID:21800180

An effective method of employing 3-aminopropyldimethylethoxysilane linker molecules to stabilize 4.4 nm FePt nanoparticle monolayer films on a SiO2 substrate as well as to prevent coalescence of the particles under 800 degrees C annealing is reported. As-deposited FePt nanoparticle films in chemically disordered face-centered-cubic phase transform to mostly chemically ordered L1 0 structure after annealing, while the nanoparticles are free from serious coalescence. The method may fulfill the pressing need to prevent nanoparticle coalescence under high-temperature annealing for the development of FePt nanoparticle based products, such as ultrahigh-density magnetic recording media and novel memory devices.

The purpose of this study is to use mixed (qualitative/quantitative) methods to determine (1) the feasibility and acceptability of using online social networking to facilitate HIV-related discussions and (2) the relationship between HIV-related online discussions and requests for a home-based HIV testing kit among men who have sex with men. Participants, primarily African American and Latino, were invited to join a "secret" group on the social networking Web site, Facebook. Peer leaders, trained in HIV prevention, posted HIV-related content. Participants were not obligated to respond to discussions or remain within the group. Participant public group conversations were qualitatively and thematically analyzed. Quantitative methods tested associations between qualitative data, participants' demographic information, and likelihood of requesting a home-based HIV testing kit. Latino and African American participants (n = 57) voluntarily used Facebook to discuss the following HIV-related topics (n = 485 conversations): prevention and testing, knowledge, stigma, and advocacy. Older participants more frequently discussed prevention and testing, stigma, and advocacy, although younger participants more frequently discussed HIV knowledge-related conversations. As the study progressed, the proportion of messages related to prevention and testing and HIV stigma increased. Multivariate analysis showed that participants posting about HIV prevention and testing (compared with those who did not) were significantly more likely to request an HIV testing kit (odds ratio, 11.14; P = 0.001). Facebook can serve as an innovative forum to increase both HIV prevention discussions and HIV testing requests among at-risk groups.

2015-01-01

This update on the epidemiology and prevention of HIV in the United States is intended to provide contextual background that will help inform an understanding of recent developments in the domestic HIV epidemic. We describe the epidemiology of HIV disease in the US and the HIV continuum of care based on data collected primarily through HIV surveillance systems led by the Centers for Disease Control and Prevention including HIV incidence, prevalence, comorbidities and death. Populations and geographic regions disparately impacted by HIV are also highlighted. The HIV prevention armamentarium is also described including behavioral approaches to prevention, the emerging availability of biomedical prevention interventions such as pre-exposure prophylaxis, and structural and population-level interventions including treatment as prevention. Finally gaps in our understanding of the epidemic are underscored and suggestions for future epidemiologic research are proposed. PMID:25960941

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

HIV Prevention: Opportunities and Challenges

Marrazzo, Jeanne M.

2016-01-01

Preexposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)-based regimens has been shown to be effective in preventing acquisition of HIV infection, with protective efficacy being dependent on adherence to treatment. Data from the PROUD (Preexposure Option for Reducing HIV in the UK) and IPERGAY (Action to Pre vent Risk Exposure By and For Gay Men) studies, the latter of which employed event-driven PrEP, showed a high rate of protective efficacy of PrEP with TDF and emtricitabine among men who have sex with men. Data from the ASPIRE (A Study to Prevent Infection With a Ring for Extended Use) study of a dapivirine vaginal ring showed a moderate rate of protective efficacy among women older than 21 years. Ongoing investigations are examining long-acting PrEP modalities and combination PrEP and contraception products. This article summarizes a presentation by Jeanne M. Marrazzo, MD, MPH, at the IAS–USA continuing education program, Improving the Management of HIV Disease, held in Washington, DC, in April 2016. PMID:28208119

The microbiome and HIV prevention strategies in women.

HIV prevention approaches that women can use and control are a priority. Results from topical and oral preexposure prophylaxis (PrEP) HIV prevention trials have produced inconsistent results in women. One of the main behavioural factors impacting effectiveness of PrEP has been suboptimal adherence. In this review, we examine biological factors that modulate topical PrEP efficacy, with particular focus on the vaginal microbiome. Genital inflammation is an independent risk factor for HIV acquisition in women. Using 16S rRNA sequencing of the vaginal microbiota, anaerobic bacteria linked with bacterial vaginosis have been shown to be associated with both genital inflammation and HIV risk. Using proteomics, it was recently discovered that a dysbiotic vaginal microbiome, comprising less than 50% Lactobacillus spp., directly influenced topical PrEP efficacy. Gardnerella vaginalis, the dominant vaginal species in dysbiotic women, was able to directly degrade tenofovir, but not dapivirine, an antiretroviral also being developed for topical PrEP. The link between bacterial vaginosis-associated organisms with HIV risk and altered tenofovir gel effectiveness underscores the importance of good vaginal health and good adherence for women to benefit maximally from topical PrEP. Altering the vaginal microbiome is one of the new directions being pursued for HIV prevention.

Cost-effectiveness analysis of annual Trichomonas vaginalis screening and treatment in HIV-positive women to prevent HIV transmission.

2014-06-01

Because of a high incidence of Trichomonas infection among HIV-positive women, annual screening and treatment are recommended. Trichomonas infection is associated with a 2-fold risk of HIV transmission. The objective of this study was to determine if annual screening is cost-effective for the prevention of new HIV cases in susceptible male partners secondary to Trichomonas infection in HIV-positive women. A decision tree analysis was constructed to model the costs of Trichomonas screening, treatment, and follow-up. 200 women cycled through the model for a period of 12 months. One hundred women were unscreened and 100 were screened and treated per recommendations. Annual Trichomonas screening and treatment saves US $553 (US $475- US $645) per woman in the prevention of HIV transmission to male partners. The cost-effectiveness of this strategy was maintained across all assumptions in a sensitivity analysis. Trichomonas screening and treatment for the purpose of decreasing new HIV infections is not only cost-effective but also cost saving in HIV-positive women. If Centers for Disease Control and Prevention treatment guidelines were followed in all HIV-positive women living in the United States, the lifetime cost of new HIV infections prevented would approximate US $159,264,000 and could potentially prevent new HIV cases secondary to female-to-male transmissions.

Antiretroviral-based HIV-1 Prevention: Antiretroviral Treatment and Pre-Exposure Prophylaxis

Celum, Connie; Baeten, Jared

2012-01-01

Antiretroviral-based HIV-1 prevention strategies – including antiretroviral treatment (ART) to reduce the infectiousness of HIV-1 infected persons and oral and topical pre-exposure prophylaxis (PrEP) for uninfected persons to prevent HIV-1 acquisition – are the most promising new approaches for decreasing HIV-1 spread. Observational studies among HIV-1 serodiscordant couples have associated ART initiation with a reduction in HIV-1 transmission risk of 80–92%, and a recent randomized trial demonstrated that earlier initiation of ART (i.e., at CD4 counts between 350 and 550 cells/mm3), in the context of virologic monitoring and adherence support, resulted in a 96% reduction in HIV-1 transmission. A number of ongoing and recently-completed clinical trials have assessed the efficacy of PrEP for HIV-1 prevention as peri-coitally administered or daily-administered 1% tenofovir gel and daily oral tenofovir and combination emtricitabine/tenofovir. Completed studies have demonstrated HIV-1 protection efficacies ranging from 39% to 75%. However, two trials in African women have shown no HIV-1 protection with PrEP; the reasons for lack of efficacy in those trials are being investigated. Adherence is likely key to efficacy of antiretrovirals for HIV-1 prevention, both as ART and PrEP. Critical unanswered questions for successful delivery of antiretroviral-based HIV-1 prevention include how to target ART and PrEP to realize maximum population benefits, whether HIV-1 infected persons at earlier stages of infection would accept ART to reduce their risk for transmitting HIV-1 and highest-risk HIV-1 negative persons would use PrEP, and whether high adherence could be sustained to achieve high effectiveness.

Glucan particles (GPs) are hollow, porous 3–5 μm microspheres derived from the cell walls of Baker's yeast (Saccharomyces cerevisiae). The 1,3-β-glucan outer shell provides for receptor-mediated uptake by phagocytic cells expressing β-glucan receptors. GPs have been used for macrophage-targeted delivery of a wide range of payloads (DNA, siRNA, protein, small molecules, and nanoparticles) encapsulated inside the hollow GPs or bound to the surface of chemically derivatized GPs. Gallium nanoparticles have been proposed as an inhibitory agent against HIV infection. Here, macrophage targeting of gallium using GPs provides for more efficient delivery of gallium and inhibition of HIV infection in macrophages compared to free gallium nanoparticles. PMID:27965897

Australia's role in HIV prevention in the developing world.

PubMed

Cooper, D A

1995-12-01

A scientist with the National Centre in HIV Epidemiology and Clinical Research at the University of New South Wales in Sydney, Australia, addresses the fact that Australians working in the area of HIV infection have been very successful in prevention, treatment, and care. In the early 1980s, a bipartisan political decision was made to foster an effective partnership between HIV-infected communities, health care providers, and governments. HIV-infected communities included sex workers, prisoners, Aboriginal people, and high profile gay community activists. These three different groups succeeded in forming such a partnership, as reflected in the fact that the annual number of new HIV cases is down to 500 from a peak of 3000 in 1984. A key method used to contain HIV infection was needle-and-syringe exchange programs and continuing access to needles to prevent HIV transmission in the injecting drug community. Even though Australia has all this experience and success, it had a backseat role in ushering in the UNAIDS program because Australia did not contribute a significant share of the agency's relatively small budget (US$100 million/year). If Australia were to give just 10%, it would acquire a front row seat along with the Netherlands, Sweden, Belgium, France, and the UK. These nations have the greatest say as to where UNAIDS funds go. The Australian international aid organization has recently received an increase in funds, $110 million for 4 years to spend on four areas, one of which is HIV/AIDS. Australia has just allocated $25 million for a 5-year program for HIV/STD (sexually transmitted disease) prevention in Indonesia. This money would have been able to buy Australia a leading role in UNAIDS. Australians need to reassess their priorities. Australians can help their neighbors in the Asia-Pacific region move away from their denial of HIV to HIV prevention and care. They can conduct clinical trials of shorter and more user-friendly regimens of antiviral drugs that

Approximately 1.5 million HIV-positive women become pregnant annually. Without treatment, up to 45% will transmit HIV to their infants, primarily through breastfeeding. These numbers highlight that HIV acquisition is a major health concern for women and children globally. They also emphasize the urgent need for novel approaches to prevent HIV acquisition that are safe, effective and convenient to use by women and children in places where they are most needed. 4'-Ethynyl-2-fluoro-2'-deoxyadenosine, a potent NRTI with low cytotoxicity, was administered orally to NOD/SCID/γc -/- mice and to bone marrow/liver/thymus (BLT) humanized mice, a preclinical model of HIV infection. HIV inhibitory activity in serum, cervicovaginal secretions and saliva was evaluated 4 h after administration. 4'-Ethynyl-2-fluoro-2'-deoxyadenosine's ability to prevent vaginal and oral HIV transmission was evaluated using highly relevant transmitted/founder viruses in BLT mice. Strong HIV inhibitory activity in serum, cervicovaginal secretions and saliva obtained from animals after a single oral dose of 4'-ethynyl-2-fluoro-2'-deoxyadenosine (10 mg/kg) demonstrated efficient drug penetration into relevant mucosal sites. A single daily oral dose of 4'-ethynyl-2-fluoro-2'-deoxyadenosine resulted in efficient prevention of vaginal and oral HIV transmission after multiple high-dose exposures to transmitted/founder viruses in BLT humanized mice. Our data demonstrated that 4'-ethynyl-2-fluoro-2'-deoxyadenosine efficiently prevents both vaginal and oral HIV transmission. Together with 4'-ethynyl-2-fluoro-2'-deoxyadenosine's relatively low toxicity and high potency against drug-resistant HIV strains, these data support further clinical development of 4'-ethynyl-2-fluoro-2'-deoxyadenosine as a potential pre-exposure prophylaxis agent to prevent HIV transmission in women and their infants. © The Author 2016.

The purpose of this preliminary study was to assess the HIV/AIDS prevention needs, services, and resources in Liberia, including the readiness of local providers to conduct HIV/AIDS-related prevention programs based on a set of six key dimensions (prevention needs, knowledge, leadership, environment, risky behaviors, and resources). A valid self-administered qualitative-based health survey, based on a community readiness model, was utilized as the primary data collection source. A cross-sectional design that utilized a convenient sample of key informants such as health coordinators, program directors, and health administrator from both public and private HIV/AIDS-based organizations was used. Furthermore, an extensive review of the National Library of Medicine database of published articles from mid-1980 to 2002 was simultaneously conducted to gauge the extent of scientific publications on HIV/AIDS-related prevention services in Liberia. The findings from this study strongly suggest that Liberia is in a stage of vague awareness, as defined by the Tri-Ethnic Center community readiness framework, regarding HIV/AIDS-related activities, including a significant lack of HIV/AIDS-related resources and scientific publications. Accordingly, there is a critical need to acquire adequate resources and build capacity to implement effective HIV/AIDS-related prevention programming services in order to avert the negative public health consequences associated with HIV/AIDS, including the implementation of relevant evaluation and dissemination strategies. Most importantly, this model has the potential to be utilized in other resource-constraint settings, especially in the developing world, to assess prevention-related resources and programmatic readiness. This is the first published study to evaluate Liberia's HIV/AIDS prevention resources and to systematically document the extent and magnitude of the HIV/AIDS crises in the country.

Early achievements in biomedical approaches for HIV prevention included physical barriers (condoms), clean injection equipment (both for medical use and for injection drug users), blood and blood product safety, and prevention of mother to child transmission. In recent years, antiretroviral drugs to reduce risk of transmission (when the infected person takes the medicines; treatment as prevention or TasP) or reduce risk of acquisition (when the seronegative person takes them; pre-exposure prophylaxis or PrEP) have proven efficacious. Circumcision of men has also been a major tool relevant for higher prevalence regions such as sub-Saharan Africa. Well-established prevention strategies in the control of sexually transmitted diseases and tuberculosis are highly relevant for HIV (i.e., screening, linkage to care, early treatment, and contact tracing). Unfortunately, only slow progress is being made in some available HIV prevention strategies such as family planning for HIV-infected women who do not want more children and prevention mother-to-child HIV transmission. Current studies seek to integrate strategies into approaches that combine biomedical, behavioral, and structural methods to achieve prevention synergies. This review identifies the major biomedical approaches demonstrated to be efficacious that are now available. We also highlight the need for behavioral risk reduction and adherence as essential components of any biomedical approach. PMID:23673881

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

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.

Clinical trial data have shown that oral pre-exposure prophylaxis (PrEP) is efficacious when taken as prescribed; however, PrEP adherence is complex and must be understood within the context of variable risk for HIV infection and use of other HIV prevention methods. Different levels of adherence may be needed in different populations to achieve HIV prevention, and the optimal methods for achieving the necessary adherence for both individual and public health benefits are unknown. Guidance for PrEP use must consider these questions to determine the success of PrEP-based HIV prevention programs. In this article, we propose a new paradigm for understanding and measuring PrEP adherence, termed prevention-effective adherence, which incorporates dynamic HIV acquisition risk behaviors and the use of HIV alternative prevention strategies. We discuss the need for daily PrEP use only during periods of risk for HIV exposure, describe key issues for measuring and understanding relevant behaviors, review lessons from another health prevention field (i.e., family planning), and provide guidance for prevention-effective PrEP use. Moreover, we challenge emerging calls for sustained, near perfect PrEP adherence regardless of risk exposure and offer a more practical and public health-focused vision for this prevention intervention.

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.

We examined trends in perinatal HIV prevention interventions in New York City implemented during 1994 to 2003 to ascertain the success of the interventions in reducing perinatal transmission. We used data obtained from infant records at 22 hospitals. We used multiple logistic regression to analyze factors associated with prenatal care and perinatal HIV transmission. We analyzed data for 4729 perinatally HIV-exposed singleton births. Of mothers with prenatal care data, 92% had prenatal care. The overall proportion who received prenatal care and were diagnosed with HIV before delivery was 86% in 1994 to 1996 and 90% in 1997 to 2003. Use of prenatal antiretrovirals among mothers who received prenatal care was 63% in 1994 to 1996 and 82% in 1997 to 2003. From 1994 to 2003, cesarean births among the entire sample increased from 15% to 55%. During 1997 to 2003, the perinatal HIV transmission rate among the entire sample was 7%; 45% of mothers of infected infants had missed opportunities for perinatal HIV prevention. During 1997 to 2003, maternal illicit drug use was significantly associated with lack of prenatal care. Lack of prenatal, intrapartum, and neonatal antiretrovirals; maternal illicit drug use; and low birthweight were significantly associated with perinatal HIV transmission. Interventions for perinatal HIV prevention can successfully decrease HIV transmission rates. Ongoing perinatal HIV surveillance allows for monitoring the implementation of guidelines to prevent mother-to-child transmission of HIV and determining factors that may contribute to perinatal HIV transmission.

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. PMID:17985230

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.

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

Cost-effectiveness of HIV prevention interventions in Andhra Pradesh state of India

PubMed Central

2010-01-01

Background Information on cost-effectiveness of the range of HIV prevention interventions is a useful contributor to decisions on the best use of resources to prevent HIV. We conducted this assessment for the state of Andhra Pradesh that has the highest HIV burden in India. Methods Based on data from a representative sample of 128 public-funded HIV prevention programs of 14 types in Andhra Pradesh, we have recently reported the number of HIV infections averted by each type of HIV prevention intervention and their cost. Using estimates of the age of onset of HIV infection, we used standard methods to calculate the cost per Disability Adjusted Life Year (DALY) saved as a measure of cost-effectiveness of each type of HIV prevention intervention. Results The point estimates of the cost per DALY saved were less than US $50 for blood banks, men who have sex with men programmes, voluntary counselling and testing centres, prevention of parent to child transmission clinics, sexually transmitted infection clinics, and women sex worker programmes; between US $50 and 100 for truckers and migrant labourer programmes; more than US $100 and up to US $410 for composite, street children, condom promotion, prisoners and workplace programmes and mass media campaign for the general public. The uncertainty range around these estimates was very wide for several interventions, with the ratio of the high to the low estimates infinite for five interventions. Conclusions The point estimates for the cost per DALY saved from the averted HIV infections for all interventions was much lower than the per capita gross domestic product in this Indian state. While these indicative cost-effectiveness estimates can inform HIV control planning currently, the wide uncertainty range around estimates for several interventions suggest the need for more firm data for estimating cost-effectiveness of HIV prevention interventions in India.

Paying for Prevention: Challenges to Health Insurance Coverage for Biomedical HIV Prevention in the United States

2014-01-01

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 transmission law in the age of treatment-as-prevention.

PubMed

Haire, Bridget; Kaldor, John

2015-12-01

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.

Gold-nanoparticle (AuNP) based colorimetric assays have been formulated for different biomolecular interactions. With this assay the probe such as antibody immobilized on the Au surface and in the presence of appropriate binding partner (antigen), will interact with each other on the Au surface. By following this strategy, herein we formulated a detection system with two anti-HIV-Tat antibodies, Mono (McAb) - and polyclonal (PcAb) by immobilizing them independently with different AuNPs. Under this condition, these two antibodies are under dispersed condition, and in the presence of HIV-Tat antigen, these molecules will be connected and forms the aggregation of AuNPs. This strategy yield rapid results, can be monitored by the spectral changes in UV-Vis spectrophotometry. Experiments were performed with two different methods using two anti-HIV-Tats monoclonal and one Polyclonal antibody against the antigen HIV-Tat. Between these methods conjugation of HIV-Tat and McAb on the AuNP followed by addition of PcAb yielded better results.

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.

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

Silver nanoparticles are broad-spectrum bactericidal and virucidal compounds

The advance in nanotechnology has enabled us to utilize particles in the size of the nanoscale. This has created new therapeutic horizons, and in the case of silver, the currently available data only reveals the surface of the potential benefits and the wide range of applications. Interactions between viral biomolecules and silver nanoparticles suggest that the use of nanosystems may contribute importantly for the enhancement of current prevention of infection and antiviral therapies. Recently, it has been suggested that silver nanoparticles (AgNPs) bind with external membrane of lipid enveloped virus to prevent the infection. Nevertheless, the interaction of AgNPs with viruses is a largely unexplored field. AgNPs has been studied particularly on HIV where it was demonstrated the mechanism of antiviral action of the nanoparticles as well as the inhibition the transmission of HIV-1 infection in human cervix organ culture. This review discusses recent advances in the understanding of the biocidal mechanisms of action of silver Nanoparticles. PMID:21812950

Currently, there is no cure and no preventive vaccine for HIV/AIDS. Combination antiretroviral therapy has dramatically improved treatment, but it has to be taken for a lifetime, has major side effects and is ineffective in patients in whom the virus develops resistance. Nanotechnology is an emerging multidisciplinary field that is revolutionizing medicine in the 21st century. It has a vast potential to radically advance the treatment and prevention of HIV/AIDS. In this review, we discuss the challenges with the current treatment of the disease and shed light on the remarkable potential of nanotechnology to provide more effective treatment and prevention for HIV/AIDS by advancing antiretroviral therapy, gene therapy, immunotherapy, vaccinology and microbicides.

ABSTRACT Treatment of individuals coinfected with human immunodeficiency virus (HIV) type 1 and Mycobacterium tuberculosis is challenging due to the prolonged treatment requirements, drug toxicity, and emergence of drug resistance. Mononuclear phagocytes (MP; macrophages) are one of the natural reservoirs for both HIV and M. tuberculosis. Here, the treatment of HIV and M. tuberculosis coinfection was studied by preloading human macrophages with MP-targeted gallium (Ga) nanoparticles to limit subsequent simultaneous infection with both HIV and M. tuberculosis. Ga nanoparticles provided sustained drug release for 15 days and significantly inhibited the replication of both HIV and M. tuberculosis. Addition of Ga nanoparticles to MP already infected with M. tuberculosis or HIV resulted in a significant decrease in the magnitude of these infections, but the magnitude was less than that achieved with nanoparticle preloading of the MP. In addition, macrophages that were coinfected with HIV and M. tuberculosis and that were loaded with Ga nanoparticles reduced the levels of interleukin-6 (IL-6) and IL-8 secretion for up to 15 days after drug loading. Ga nanoparticles also reduced the levels of IL-6 and IL-8 secretion by ionomycin- and lipopolysaccharide-induced macrophages, likely by modulating the IκB kinase-β/NF-κB pathway. Delivery of Ga nanoparticles to macrophages is a potent long-acting approach for suppressing HIV and M. tuberculosis coinfection of macrophages in vitro and sets the stage for the development of new approaches to the treatment of these important infections.

Successful treatment and control of HIV/AIDS is one of the biggest challenges of 21st century. More than 33 million individuals are infected with HIV worldwide and more than 2 million new cases of HIV infection have been reported. The situation demands development of effective prevention strategies to control the pandemic of AIDS. Due to lack of availability of an effective HIV vaccine, antiretroviral drugs and nucleic acid therapeutics like siRNA have been explored for HIV prophylaxis. Clinical trials shave shown that antiretroviral drugs, tenofovir and emtricitabine can offer some degree of HIV prevention. However, complete prevention of HIV infection has not been achieved yet. Nanotechnology has brought a paradigm shift in the diagnosis, treatment and prevention of many diseases. The current review discusses potential of various nanocarriers such as dendrimers, polymeric nanoparticles, liposomes, lipid nanocarriers, drug nanocrystals, inorganic nanocarriers and nanofibers in improving efficacy of various modalities available for HIV prophylaxis.

Biomedical HIV prevention trials enroll sexually active women at risk of HIV and often discontinue study product during pregnancy. We assessed risk factors for pregnancy and HIV acquisition, and the effect of pregnancy on time off study drug in HIV Prevention Trials Network 039. A total of 1358 HIV negative, herpes simplex virus type 2-seropositive women from South Africa, Zambia, and Zimbabwe were enrolled and followed for up to 18 months. A total of 228 pregnancies occurred; time off study drug due to pregnancy accounted for 4% of woman-years of follow-up among women. Being pregnant was not associated with increased HIV risk (hazard ratio 0.64, 95% confidence interval 0.23-1.80, P = 0.40). However, younger age was associated with increased risk for both pregnancy and HIV. There was no association between condom use as a sole contraceptive and reduced pregnancy incidence; hormonal contraception was not associated with increased HIV risk. Bacterial vaginosis at study entry was associated with increased HIV risk (hazard ratio 2.03, P = 0.02). Pregnancy resulted in only a small amount of woman-time off study drug. Young women are at high risk for HIV and are an appropriate population for HIV prevention trials but also have higher risk of pregnancy. Condom use was not associated with reduced incidence of pregnancy.

Background Tuberculosis (TB) is an important cause of illness and death in HIV-positive children living in areas of high TB prevalence. We know that isoniazid prophylaxis prevents TB in HIV-negative children following TB exposure, but there is uncertainty related to its role in TB preventive treatment in HIV-positive children. Objectives To summarise the effects of TB preventive treatment versus placebo in HIV-positive children with no known TB contact on active TB, death, and reported adverse events. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE/PubMed, Embase and two trial registers up to February 2017. Selection criteria We included trials of HIV-positive children with and without known TB exposure, randomized to receive TB preventive treatment or placebo. Data collection and analysis Two review authors independently used the study selection criteria, assessed risk of bias, and extracted data. We assessed effects using risk, incidence rate and hazard ratios and assessed the certainty of evidence using GRADE. Main results We included three trials, involving 991 participants, below the age of 13 years, from South Africa and Botswana. Children were randomized to isoniazid prophylaxis or placebo, given daily or three times weekly. The median length of follow-up ranged from 5.7 to 34 months; some were on antiretroviral therapy (ART). In HIV-positive children not on ART, isoniazid prophylaxis may reduce the risk of active TB (hazard ratio (HR) 0.31, 95% confidence interval (CI) 0.11 to 0.87; 1 trial, 240 participants, low certainty evidence), and death (HR 0.46, 95% CI 0.22 to 0.95; 1 trial, 240 participants, low certainty evidence). One trial (182 participants) reported number of children with laboratory adverse events, which was similar between the isoniazid prophylaxis and placebo groups. No clinical adverse events were reported. In HIV-positive children on ART, we do not know if isoniazid prophylaxis reduces the

Epistemic fault lines in biomedical and social approaches to HIV prevention

PubMed Central

2011-01-01

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.

In the United States, new HIV diagnoses are highest in the South and among African Americans and are increasing in rural areas. Youth remain highly vulnerable to HIV infection globally. The epidemiology of HIV infections among people who inject drugs is changing, with overdose deaths, a major public health concern. Phylogenetics are being used to identify HIV transmission clusters and hotspots, which can inform prevention efforts. Vaginal microbial dysbiosis and proteomic alterations are associated with increased risk of HIV acquisition, as are the pregnancy and postpartum periods. HIV testing is a central first step for the HIV care and treatment continua, and several innovative strategies to expand HIV testing coverage and frequency show promise. Preexposure prophylaxis (PrEP) uptake is rapidly increasing in some cities, with reductions of new infections at the population level, but use is lower among African Americans and Latinos, youth, cis- and transgender women, and people who inject drugs. PrEP continuation remains a challenge. Two open-label extension studies of the dapivirine vaginal ring demonstrated high uptake, adherence, and reduced HIV infections.

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.

Background We aimed to identify the prevalence of cardiovascular risk factors, and investigate preventive cardiovascular medication use and achievement of targets as per Dutch cardiovascular risk management guidelines among human immunodeficiency virus (HIV)-positive and HIV-negative individuals. Design The design was a cross-sectional analysis within an ongoing cohort study. Methods Data on medication use and cardiovascular disease prevalence were available for 528 HIV-positive and 521 HIV-negative participants. We identified cardiovascular risk factors and applied cardiovascular risk management guidelines, mainly focusing on individuals eligible for (a) primary prevention because of high a priori cardiovascular risk, or for (b) secondary prevention. Results One hundred and three (20%) HIV-positive and 77 (15%) HIV-negative participants were classified as having high cardiovascular risk; 53 (10%) HIV-positive and 27 (5%) HIV-negative participants were eligible for secondary prevention. Of HIV-positive individuals 57% at high cardiovascular risk and 42% of HIV-positive individuals eligible for secondary prevention had systolic blood pressures above guideline-recommended thresholds. Cholesterol levels were above guideline-recommended thresholds in 81% of HIV-positive individuals at high cardiovascular risk and 57% of HIV-positive individuals eligible for secondary prevention. No statistically significant differences were observed between HIV-positive and HIV-negative participants regarding achievement of targets, except for glycaemic control (glycated haemoglobin ≤ 53 mmol/mol) among individuals using diabetes medication (90% vs 50%, p = 0.017) and antiplatelet/anticoagulant use for secondary prevention (85% vs 63%, p = 0.045), which were both superior among HIV-positive participants. Conclusions Cardiovascular risk management is suboptimal in both HIV-positive and HIV-negative individuals and should be improved.

Problematics of empowerment: sex worker HIV prevention in the Pacific.

PubMed

McMillan, Karen E; Worth, Heather

2016-12-01

A recent overview of HIV/STI prevention programmes for sex workers in the Pacific region indicates that, despite a regional policy shift from universal to targeted interventions, Pacific Island countries currently lack core HIV/STI prevention services for sex workers. Across the region, condom distribution, peer outreach and support services for sex workers have ceased even in countries where such programmes had previously existed. This article cautions that the endorsement of empowerment projects does not negate the important role of condom access in HIV and STI prevention efforts for Pacific sex workers. While community empowerment underpins, and is essential to the sustainability of, effective interventions, it does not constitute an adequate form of HIV and STI prevention in and of itself. We contend that in the context of the Pacific Islands, timely and effective HIV prevention measures must specifically attend to the implementation of, and sustained support for, behavioural interventions such as sex-worker-specific peer education, condom and lubricant distribution, and access to appropriate sexual health services. Further, the responsibility for delivery of these should not be borne solely by fledgling sex worker organizations and communities. The evolution of targeted interventions in the Pacific and the current lack of funded condom distribution programmes highlight a more generalizable imperative within HIV prevention to ensure that behaviour change efforts are not considered to be extraneous to, or rendered redundant by, empowerment-based interventions. © The Author 2015.

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

Outpatient substance abuse treatment and HIV prevention: an update.

Testing and counseling, along with community outreach, have been identified as valuable in the prevention of human immunodeficiency virus (HIV) and other blood-borne diseases. This article assesses the extent to which outpatient substance abuse treatment (OSAT) programs provide such services. Longitudinal data for 1988-2000 were analyzed from the National Drug Abuse Treatment System Survey (NDATSS). Random-effects regression was used to examine factors associated with the provision of prevention services. HIV testing, which had became more common between 1990 and 1995, continued to proliferate between 1995 and 2000. The proportion of units that provide HIV testing and counseling increased from 66% to 86%. The proportion of units that provide HIV community outreach increased significantly before 1995 but then slightly decreased from 77% to 73% between 1995 and 2000. In conclusion, HIV testing and counseling widely proliferated in OSAT care. However, OSAT units remain less likely to offer HIV community outreach services.

Young people and HIV prevention in Australian schools.

PubMed

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.

HIV Prevention Among Diverse Young MSM: Research Needs, Priorities, and Opportunities.

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.

What is the place of pre-exposure prophylaxis in HIV prevention?

De Man, Jeroen; Colebunders, Robert; Florence, Eric; Laga, Marie; Kenyon, Christopher

2013-01-01

New tools are needed to bring down ongoing high HIV incidence. This review aims to evaluate the place of one of these new tools (pre-exposure prophylaxis) in a comprehensive prevention strategy. Several trials have demonstrated the safety and the efficacy of pre-exposure prophylaxis in HIV prevention. Two large trials have, however, failed to show such efficacy. This was likely due to poor adherence in these trials. New forms of long-acting pre-exposure prophylaxis currently in trials may deal with these problems of low adherence. Pre-exposure prophylaxis has been demonstrated to be cost-effective within certain settings. The introduction of pre-exposure prophylaxis into prevention programs needs to be carefully thought through. For example, pre-exposure prophylaxis-induced risk compensation, at both an individual and population level, could undermine other aspects of a comprehensive HIV prevention program. In conclusion, pre-exposure prophylaxis could be a useful additional tool for the prevention of HIV in specific high-risk groups. It should be implemented in a way that deals with issues such as ensuring high adherence and ensuring that pre-exposure prophylaxis does not detract from, but complements, other more fundamental elements of HIV prevention programs.

HIV/AIDS epidemiology, pathogenesis, prevention, and treatment

The HIV-1 pandemic is a complex mix of diverse epidemics within and between countries and regions of the world, and is undoubtedly the defining public-health crisis of our time. Research has deepened our understanding of how the virus replicates, manipulates, and hides in an infected person. Although our understanding of pathogenesis and transmission dynamics has become more nuanced and prevention options have expanded, a cure or protective vaccine remains elusive. Antiretroviral treatment has transformed AIDS from an inevitably fatal condition to a chronic, manageable disease in some settings. This transformation has yet to be realised in those parts of the world that continue to bear a disproportionate burden of new HIV-1 infections and are most a% ected by increasing morbidity and mortality. This Seminar provides an update on epidemiology, pathogenesis, treatment, and prevention interventions pertinent to HIV-1. PMID:16890836

Conceptualizing a Human Right to Prevention in Global HIV/AIDS Policy

Meier, Benjamin Mason; Brugh, Kristen Nichole; Halima, Yasmin

2012-01-01

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.

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. 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. 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. About 44% of participants reported a one-on-one conversation with a healthcare 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. 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.

Prevention Strategies Against HIV Transmission: A Proactive Approach.

Human immunodeficiency virus (HIV) has now transformed into a manageable chronic condition. Highly active antiretroviral therapy (HAART) has proven efficacious at controlling the disease progression. Based on compelling evidence, the Department of Health and Human Services (DHHS) and the Infectious Disease Society of America (IDSA) developed guidelines for the management of persons infected with HIV. However, there are approximately 50 000 new cases of HIV in the United States each year. In this article, we review proactive methods to reduce the transmission of HIV, which include reinforcing patient education, gel-coated condoms that destroy HIV, HIV vaccinations, and adequately utilizing pre-exposure prophylaxis (PrEP), and post-exposure prophylaxis (PEP). Further development and consistent utilization of innovative prevention tools can significantly reduce the incidence of HIV infections regardless of HIV status.

Setting government priorities in preventing HIV / AIDS.

PubMed

Ainsworth, M

1998-03-01

Since no cure has yet been found for AIDS and an effective vaccine is far off, preventing HIV infection by changing individual behavior is the key to stopping the AIDS epidemic in developing countries. People who have many sex partners and do not use condoms, and people who inject drugs and share unsterilized injecting equipment have the greatest risk of contracting HIV and infecting others. How quickly and extensively an HIV/AIDS epidemic spreads in a given population depends largely upon the extent to which people with many sex partners mix with people with fewer partners. A World Bank research report has, however, found that people who engage in high-risk behavior act to reduce their risk of contracting and spreading HIV when they have the knowledge and means to do so and a supportive community. The report highlights the following strategies to reduce risky behavior: providing information, lowering the costs of safer behavior, and raising the costs of risky behavior. Governments' main responsibilities in preventing the spread of HIV/AIDS are reducing the negative externalities of high-risk behavior and producing public goods. Without government action, individuals and firms will not have the incentives to do what is necessary. The need to act now and mobilizing political support are discussed.

Moving Beyond of The Alphabet Soup of HIV Prevention

It is time to scrap the “ABCs” and elevate the debate on HIV prevention beyond the incessant controversies over individual interventions. The ABCs are a woefully incomplete list of necessary prevention interventions, but the goal should not be to just add more letters to the prevention alphabet. Instead, advancing global HIV prevention means holding national gover nments, donors and global agencies accountable for prevention efforts that are tailored to national epidemics, bring quality interventions to a scale, and address environmental factors in vulnerability. The debate is not so much about one intervention or another, but whether countries have a comprehensive prevention effort in place that responds to their own unique situations. PMID:18641471

HIV prevention needs for men who have sex with men in Swaziland.

Sithole, Bhekie

2017-12-01

Men who have sex with men (MSM) have a high HIV burden and also often face multiple other challenges accessing HIV services, including legal and social issues. Although Swaziland recently started responding with interventions for MSM, significant gaps still exist both in information and programming. This study aimed to explore the HIV prevention needs of MSM in Swaziland, including factors elevating their risks and vulnerabilities to HIV infection; to find out what HIV prevention strategies exist; and to determine how best to meet the prevention needs of MSM. A total of 50 men who reported anal sex with other men in the past 12 months were recruited through simple respondent driven sampling. They completed either a structured quantitative survey (n = 35) or participated in a semi-structured qualitative interview (n = 15). Both quantitative and qualitative findings indicated perceived and experienced stigma among MSM. This predominantly manifested as internalised stigma, which may lead to alcohol abuse and sexual risky behaviours. At least 83% (29/35) of the quantitative sample had been labelled with derogatory terms because of their sexual orientation, while 66% (23/35) had experienced being avoided. There was limited knowledge of risk practices: When asked, 54% (19/35) of quantitative respondents reported that vaginal and anal sex carry an equal risk of HIV infection. Participants also had little knowledge on new HIV prevention methods such as pre-exposure prophylaxis (PrEP) and rectal microbicides. MSM needs included safe spaces in form of drop-in centres and non-hostile HIV services. Although Swaziland recently started interventions for key populations, including MSM, there is still a general lack on information to inform managers and implementers on the HIV prevention needs of MSM in Swaziland. Such information is crucial for designers of official and HIV programmes. Research is needed to increase knowledge on the HIV prevention needs for key populations

PrEP as peri-conception HIV prevention for women and men

PubMed Central

Heffron, Renee; Pintye, Jillian; Matthews, Lynn T.; Weber, Shannon; Mugo, Nelly

2016-01-01

Daily oral tenofovir (TDF)-based pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy and recommended for men and women with substantial risk of HIV acquisition. The peri-conception period, the stage prior to pregnancy when condom use is necessarily reduced, has elevated HIV risk that can be mitigated by PrEP use. Data from a randomized trial suggest that peri-conception PrEP use by HIV-seronegative women does not increase the risk of pregnancy loss, birth defects or congenital anomalies, preterm birth, or infant growth faltering. Women considering PrEP use throughout pregnancy must weigh the known increased risk of HIV acquisition with unknown risks of drug effects on infant growth. PrEP has been used safely by HIV-seronegative men with HIV-seropositive female partners who have become pregnant. As an effective user-controlled HIV prevention strategy, PrEP offers autonomy and empowerment for HIV prevention and can be recommended alongside antiretroviral therapy, fertility screening, vaginal self-insemination, intercourse timed to peak fertility, medically assisted reproduction, and other safer conception strategies to provide multiple options. The integration of PrEP into safer conception programs is warranted and will safely reduce HIV transmission to women, men and children during the peri-conception period. PMID:26993627

Articulating a rights-based approach to HIV treatment and prevention interventions.

PubMed

Barr, David; Amon, Joseph J; Clayton, Michaela

2011-09-01

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.

Following universal access to antiretroviral therapy in Thailand, evidence from National AIDS Spending Assessment indicates a decreasing proportion of expenditure on prevention interventions. To prompt policymakers to revitalize HIV prevention, this study identifies a comprehensive list of HIV/AIDs preventive interventions that are likely to be effective and cost-effective in Thailand. A systematic review of the national and international literature on HIV prevention strategies from 1997 to 2008 was undertaken. The outcomes used to consider the effectiveness of HIV prevention interventions were changes in HIV risk behaviour and HIV incidence. Economic evaluations that presented their results in terms of cost per HIV infection averted or cost per quality-adjusted life year (QALY) gained were also included. All studies were assessed against quality criteria. The findings demonstrated that school based-sex education plus life-skill programs, voluntary and routine HIV counselling and testing, male condoms, street outreach programs, needle and syringe programs, programs for the prevention of mother-to-child HIV transmission, male circumcision, screening blood products and donated organs for HIV, and increased alcohol tax were all effective in reducing HIV infection among target populations in a cost-effective manner. We found very limited local evidence regarding the effectiveness of HIV interventions amongst specific high risk populations. This underlines the urgent need to prioritise health research resources to assess the effectiveness and cost-effectiveness of HIV interventions aimed at reducing HIV infection among high risk groups in Thailand.

In this study we explored the level of awareness and practice on HIV prevention among married couples from selected communities in Malawi. We carried out the study from October to December, 2008 in four communities, two each from Chiradzulu and Chikhwawa districts of Malawi. We conducted face-to-face in-depth interviews with 30 couples in each district using a semi-structured interview guide. The interviews lasted approximately 60-90 minutes. The husbands and wives were interviewed separately. The interviews were audio taped using a digital recorder. We wrote field notes during data collection and later reviewed them to provide insights into the data collection process. We computed descriptive statistics from the demographic data using SPSS version 16.0. We analyzed qualitative data using Atlas ti 5.0 computer software. The coded data generated themes and we present the themes in qualitative narration. The couples' ages ranged from 20 to 53 years, the majority (52%) being in the 20-31 year age group. Most of the couples (67%) attained only primary school education and 84% had been married only to the current partner. Most couples (83%) depended upon substance farming and 47% had been married for 3 to 9 years. The number of children per couple ranged from 1 to 10, most couples (83%) having between 1 and 5 children. All couples were aware of HIV prevention methods and talked about them in their marriages. Both wives and husbands initiated the discussions. Mutual fidelity and HIV testing were appropriate for couples to follow the HIV prevention methods. For most couples (54) there was mutual trust between husbands and wives, and members of only a few couples (6) doubted their partners' ability to maintain mutual fidelity. Actual situations of marital infidelity were however detected among 25 couples and often involved the husbands. A few couples (5) had been tested for HIV. All couples did not favor the use of condoms with a marriage partner as an HIV prevention

Executive Director Peter Piot of the Joint United Nations Programme on HIV/AIDS called on companies to initiate aggressive measures to prevent the further spread of HIV. The global total of HIV cases reached 23 million in 1996. The epidemic threatens the growth of the global economy, particularly in developing nations where private corporations are seeking new markets. The economic toll due to AIDS is devastating because it affects young people who are at the height of their earning power. Piot offered examples of prevention initiatives that have been undertaken by companies to control the epidemic.

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.

Exploring the role of economic empowerment in HIV prevention.

PubMed

Kim, Julia; Pronyk, Paul; Barnett, Tony; Watts, Charlotte

2008-12-01

It has been argued that women's economic vulnerability and dependence on men increases their vulnerability to HIV by constraining their ability to negotiate the conditions, including sexual abstinence, condom use and multiple partnerships, which shape their risk of infection. In the face of escalating infection rates among women, and particularly young women, many have pointed to the potential importance of economic empowerment strategies for HIV prevention responses. Global evidence suggests that the relationship between poverty and HIV risk is complex, and that poverty on its own cannot be viewed simplistically as a driver of the HIV epidemic. Rather, its role appears to be multidimensional and to interact with a range of other factors, including mobility, social and economic inequalities and social capital, which converge in a particularly potent way for young women living in southern Africa. To date, there have been few interventions that have explicitly attempted to combine economic empowerment with the goal of HIV prevention, and even fewer that have been rigorously evaluated. This paper explores how programmes such as microfinance, livelihood training and efforts to safeguard women's food security and access to property have begun to incorporate an HIV prevention focus. Although such circumscribed interventions, by themselves, are unlikely to lead to significant impacts on a national or regional scale, they are useful for testing cross-sectoral partnership models, generating practical lessons and providing a metaphor for what might be possible in promoting women's economic empowerment more broadly. Despite numerous calls to 'mainstream AIDS' in economic development, cross-sectoral responses have not been widely taken up by government or other stakeholders. We suggest potential reasons for limited progress to date and conclude by presenting programme and policy recommendations for further exploring and harnessing linkages between economic empowerment and HIV

The number of refugees increased in recent years due to factors worldwide, including violence, wars, political strife, and natural disasters. Refugees who are Hispanic women (RHW) in South Florida are a vulnerable population at risk of acquiring HIV infection. Although studies have shown a relationship between self-efficacy for HIV prevention and behavior changes, none have studied RHW. The purpose of this study was to assess whether predictors suggested by the literature were related to self-efficacy for HIV prevention in a sample of RHW. The study is a secondary analysis that uses baseline data from a randomized controlled experimental study, SEPA. A total of 99 refugee Hispanic women from South Florida, 18-50 years of age, participated in the study. There were two predictors of self-efficacy. HIV knowledge was positively related to self-efficacy, and living with a partner was inversely related to self-efficacy for HIV prevention. Culturally competent sexual health education interventions in this population may impact self-efficacy for HIV prevention.

Condom acceptance and HIV prevention in reproductive health: the challenges.

PubMed

The AIDS epidemic weighs heavily on the already burdened health care delivery systems of developing countries especially in central Africa. AIDS not only incurs high morbidity and mortality but has a severe impact on productivity, economic infrastructures, and development in those countries which need them the most. HIV is mainly spread through heterosexual intercourse in central Africa. Vertical transmission of HIV and breast feeding are other means. The key vehicle of HIV transmission in the US is still homosexual intercourse. Sexually transmitted diseases (STDs) facilitate HIV transmission via intercourse. Research shows that subsequent infection by other STDs hastens the development of AIDS in HIV-infected people. Some evidence indicates that pregnancy increases the risk of developing AIDS in a woman who is positive for HIV. The main means to prevent HIV transmission is the condom. Yet, in Rwanda, only 7% of women had ever used condoms despite the high rate (32%) of HIV-positive serology. The University of Zimbabwe Medical School believes adolescents are the most appropriate starting point for AIDS prevention since they tend to experiment with sexual behaviors. Its youth counseling program involves education and prevention messages within and outside educational settings through youth meeting places, youth workers, and other mass media. It hosts workshops at meeting places which use the problem solving approach to risk reduction behavior. The program invites schools, churches, and other educational settings to form Anti-AIDS Clubs. It advocates use of drama and music to promote AIDS awareness. The program has also branched out into community counseling where it works to eliminate the stigma and guilt associated with talking about sexual transmission of AIDS. Governments must learn who the STD and HIV transmission high risk groups are and then target them with information, education, and communication AIDS prevention programs.

Antiretroviral Therapy for the Prevention of HIV Transmission: What Will It Take?

2014-01-01

The evidence in support of use of antiretroviral therapy (ART) for prevention of human immunodeficiency virus (HIV) transmission is encouraging and has stimulated optimism for achieving a dramatic change in the trajectory of the HIV epidemic. Yet, there are substantial challenges that, if not addressed, could be the Achilles’ heel for this concept. These challenges require strengthening every step of the HIV care continuum, including expansion of HIV testing to reach all those with HIV infection, effective linkage to and retention in care, timely initiation of ART, and high levels of treatment adherence with viral load suppression. Also important is the identification of individuals with acute HIV infection whose contribution to HIV transmission may be substantial. Implementation research is needed to identify strategies that address these challenges and to determine the efficacy of ART for prevention in key populations as well as to evaluate the effectiveness of combination strategies for HIV prevention at the population level.

Media messages can facilitate delivery of accurate HIV/STI-related information. This study’s purpose was to examine pre-existing media campaigns from the iMPPACS study to assess age, gender, and culturally appropriate components identified by African American females who attend HBCUs. In three separate focus group sessions, 31 Black female college students (M age=20) viewed four vignettes and heard three audio-only clips, then ranked and commented on them based on perceived satisfaction of HIV prevention content and appropriateness of delivery. Conventional qualitative analysis, using NVivo software, was employed until saturation of content was achieved and themes derived. Six major themes emerged and were designated as: 1) Social media; 2) Mirror Image; 3) Visually dynamic Advertisements; 4) The Real World; 5) People, Place, Things; and 6) 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 audio-visual 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 employ recognizable voices (e.g. celebrity). Finally, messaging should be promoted on open and close circuited social media platforms. PMID:28098500

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. © The Author(s) 2013.

Persistent new HIV infections and risky behaviors underscore the need for enhanced HIV prevention. Social media interventions may promote safe sexual behaviors, increase HIV testing uptake, and promote safe injection behaviors. This review discusses how social media interventions tap into the wisdom of crowds through crowdsourcing, build peer-mentored communities, and deliver interventions through social networks. Social media HIV prevention interventions are constrained by ethical issues, low social media usage among some key populations, and implementation issues. Comprehensive measurement of social media interventions to prevent HIV is necessary, but requires further development of metrics.

Controversy surrounds the linkage of prevention counseling with emergency department (ED)-based HIV testing. Further, the effectiveness and feasibility of prevention counseling in the ED setting is unknown. We investigate these issues by conducting a preliminarily exploration of several related aspects of our ED's HIV prevention counseling and testing program. Our urban, academic ED provides formal client-centered prevention counseling in conjunction with HIV testing. Five descriptive, exploratory observations were conducted, involving surveys and analysis of electronic medical records and programmatic data focused on (1) patient perception and feasibility of prevention counseling in the ED, (2) patient perceptions of the need to link prevention counseling with testing, and (3) potential effectiveness of providing prevention counseling in conjunction with ED-based HIV testing. Of 110 ED patients surveyed after prevention counseling and testing, 98% believed privacy was adequate, and 97% reported that their questions were answered. Patients stated that counseling would lead to improved health (80%), behavioral changes (72%), follow-up testing (77%), and discussion with partners (74%). However, 89% would accept testing without counseling, 32% were willing to seek counseling elsewhere, and 26% preferred not to receive the counseling. Correct responses to a 16-question knowledge quiz increased by 1.6 after counseling (95% confidence interval 1.3 to 12.0). The program completed counseling for 97% of patients tested; however, 6% of patients had difficulty recalling the encounter and 13% denied received testing. Among patients undergoing repeated testing, there was no consistent change in self-reported risk behaviors. Participants in the ED prevention counseling and testing program considered counseling acceptable and useful, though not required. Given adequate resources, prevention counseling can be provided in the ED, but it is unlikely that all patients benefit

Allocating HIV prevention funds in the United States: recommendations from an optimization model.

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.

The promise and limitations of cash transfer programs for HIV prevention.

Fieno, John; Leclerc-Madlala, Suzanne

2014-01-01

As the search for more effective HIV prevention strategies continues, increased attention is being paid to the potential role of cash transfers in prevention programming in sub-Saharan Africa. To date, studies testing the impact of both conditional and unconditional cash transfers on HIV-related behaviours and outcomes in sub-Saharan Africa have been relatively small-scale and their potential feasibility, costs and benefits at scale, among other things, remain largely unexplored. This article examines elements of a successful cash transfer program from Latin America and discusses challenges inherent in scaling-up such programs. The authors attempt a cost simulation of a cash transfer program for HIV prevention in South Africa comparing its cost and relative effectiveness--in number of HIV infections averted--against other prevention interventions. If a cash transfer program were to be taken to scale, the intervention would not have a substantial effect on decreasing the force of the epidemic in middle- and low-income countries. The integration of cash transfer programs into other sectors and linking them to a broader objective such as girls' educational attainment may be one way of addressing doubts raised by the authors regarding their value for HIV prevention.

Marques, Joilson Santana; Gomes, Romeu; do Nascimento, Elaine Ferreira

2012-02-01

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.

The costs of HIV prevention strategies in developing countries.

1993-01-01

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. PMID:8261563

We reviewed the current human immunodeficiency virus (HIV) prevention education programmes in Singapore, discussed the challenges faced and proposed prevention education interventions for the future. Education programmes on HIV prevention have shown some success as seen by reduced visits to sex workers among the general adult population and a marked increase in condom use among brothel-based sex workers. However, we still face many challenges such as low awareness of HIV preventive strategies and high prevalence of HIV stigma in the general population. Voluntary HIV testing and condom use remain low among the priority groups such as men who have sex with men (MSM) and heterosexual men who buy sex. Casual sex has increased markedly from 1.1% in 1989 to 17.4% in 2007 among heterosexuals in Singapore, with the majority (84%) practising unprotected sex. Sex workers have moved from brothels to entertainment venues where sex work is mostly hidden with lack of access to sexually transmitted infections (STIs)/ HIV prevention education and treatment programmes. Education programmes promoting early voluntary testing is hampered because of poor access, high cost and stigma towards people living with HIV. It remains a challenge to promote abstinence and consistent condom use in casual and steady sexual relationships among heterosexuals and MSM. New ways to promote condom use by using a positive appeal about its pleasure enhancing effects rather than the traditional disease-oriented approach should be explored. Education programmes promoting early voluntary testing and acceptance of HIV-infected persons should be scaled up and integrated into the general preventive health services.

HIV epidemic control-a model for optimal allocation of prevention and treatment resources.

2014-06-01

With 33 million people living with human immunodeficiency virus (HIV) worldwide and 2.7 million new infections occurring annually, additional HIV prevention and treatment efforts are urgently needed. However, available resources for HIV control are limited and must be used efficiently to minimize the future spread of the epidemic. We develop a model to determine the appropriate resource allocation between expanded HIV prevention and treatment services. We create an epidemic model that incorporates multiple key populations with different transmission modes, as well as production functions that relate investment in prevention and treatment programs to changes in transmission and treatment rates. The goal is to allocate resources to minimize R 0, the reproductive rate of infection. We first develop a single-population model and determine the optimal resource allocation between HIV prevention and treatment. We extend the analysis to multiple independent populations, with resource allocation among interventions and populations. We then include the effects of HIV transmission between key populations. We apply our model to examine HIV epidemic control in two different settings, Uganda and Russia. As part of these applications, we develop a novel approach for estimating empirical HIV program production functions. Our study provides insights into the important question of resource allocation for a country's optimal response to its HIV epidemic and provides a practical approach for decision makers. Better decisions about allocating limited HIV resources can improve response to the epidemic and increase access to HIV prevention and treatment services for millions of people worldwide.

Objectives. We examined trends in perinatal HIV prevention interventions in New York City implemented during 1994 to 2003 to ascertain the success of the interventions in reducing perinatal transmission. Methods. We used data obtained from infant records at 22 hospitals. We used multiple logistic regression to analyze factors associated with prenatal care and perinatal HIV transmission. Results. We analyzed data for 4729 perinatally HIV-exposed singleton births. Of mothers with prenatal care data, 92% had prenatal care. The overall proportion who received prenatal care and were diagnosed with HIV before delivery was 86% in 1994 to 1996 and 90% in 1997 to 2003. Use of prenatal antiretrovirals among mothers who received prenatal care was 63% in 1994 to 1996 and 82% in 1997 to 2003. From 1994 to 2003, cesarean births among the entire sample increased from 15% to 55%. During 1997 to 2003, the perinatal HIV transmission rate among the entire sample was 7%; 45% of mothers of infected infants had missed opportunities for perinatal HIV prevention. During 1997 to 2003, maternal illicit drug use was significantly associated with lack of prenatal care. Lack of prenatal, intrapartum, and neonatal antiretrovirals; maternal illicit drug use; and low birthweight were significantly associated with perinatal HIV transmission. Conclusions. Interventions for perinatal HIV prevention can successfully decrease HIV transmission rates. Ongoing perinatal HIV surveillance allows for monitoring the implementation of guidelines to prevent mother-to-child transmission of HIV and determining factors that may contribute to perinatal HIV transmission.

Articulating A Rights-Based Approach to HIV Treatment and Prevention Interventions

2011-01-01

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.

HIV prevention trials provide a prevention package to participants to help prevent HIV acquisition. As new prevention methods are proven effective, this raises ethical and scientific design complexities regarding the prevention package or standard of prevention. Given its high HIV incidence and prevalence, South Africa has become a hub for HIV prevention research. For this reason, it is critical to study the implementation of relevant ethical-legal frameworks for such research in South Africa. This qualitative study used in-depth interviews to explore the practices and perspectives of eight members of South African research ethics committees (RECs) who have reviewed protocols for HIV vaccine trials. Their practices and perspectives are compared with ethics guideline requirements for standards of prevention.

Enhancing HIV Prevention Among Young Men Who Have Sex With Men: A Systematic Review of HIV Behavioral Interventions for Young Gay and Bisexual Men.

Men who have sex with men (MSM) represent 64.0% of people living with HIV (PLWH) over the age of 13 years. Young men who have sex with men (YMSM) are particularly affected by HIV/AIDS; the rate of HIV infection for YMSM between the ages of 13 and 24 represents 72.0% of new infections among youth. To understand the current state of the science meant to prevent HIV for YMSM, we reviewed studies of HIV behavioral prevention interventions for YMSM. Five literature databases were searched, from their inception through October 2015, using key words associated with HIV prevention intervention evaluation studies for YMSM. The review criteria included behavioral HIV/AIDS prevention interventions, articles published in English-language peer-reviewed journals, YMSM between 13 and 24 years of age, and longitudinal repeated measures design. A total of 15 YMSM behavioral HIV prevention intervention studies were identified that met inclusion criteria and reported statistically significant findings. Common outcomes included unprotected sexual intercourse, HIV/AIDS risk behavior, condom use, HIV testing, safer sex attitude, and HIV prevention communication. Participant age, representation of Black/African American YMSM, application of theoretical and model underpinnings, congruence of assessment measures used, follow-up assessment times, and application of process evaluation were inconsistent across studies. To advance HIV prevention intervention research for YMSM, future studies should be theory-based, identify common constructs, utilize standard measures, include process evaluation, and evaluate sustained change over standard periods of time. HIV prevention interventions should incorporate the needs of the diverse, well-educated, web-connected millennial generation and differentiate between adolescent YMSM (13 to 18 years of age) and young adulthood YMSM (19 to 24 years of age). Because Black/African American YMSM represent more than 50% of new HIV infections, future HIV

Obtaining the definitive data necessary to determine the safety and efficacy of using antiretroviral treatment (ART) to reduce the sexual transmission of HIV in heterosexual couples encountered an array of ethical challenges that threatened to compromise HIV Prevention Trials Network (HPTN) 052, the multinational clinical trial addressing this issue that has profound public health implications. To describe and analyze the major ethical challenges faced in HPTN 052. The ethical issues and modifications of HPTN 052 in response to these issues were cataloged by the principal investigator, the lead coordinator, and the ethicist working on the trial. The major ethical issues that were unique to the trial were then described and analyzed in light of the published literature as well as guidances and policies. The ethical challenges that must be addressed in many clinical trials, such as those related to obtaining informed consent and making provisions for ancillary care, are not described. When HPTN 052 was being designed, ethical questions emerged related to the relevance of the research question itself given data from observational research and a range of beliefs about the appropriate means of preventing and treating HIV infection and AIDS. Furthermore, ethical challenges were faced regarding site selection since there was a scientific need to conduct the research in settings where HIV incidence was high, but alternatives to study participation should be available. As in most HIV-prevention research, ethical questions surrounded the determination of the appropriate prevention package for all of those enrolled. During the course of the trial, guidance documents and policies emerged that were of direct relevance to the research questions, calling for a balancing of concerns for the research subjects and trial integrity. When the study results were made public, there was a need to ensure access to the treatment shown to be effective that in some cases differed from the

A 3-year interactive and passive training for HIV prevention education was conducted for 2,600 prisoners; 1,404 (54%) black, 1,092 (42%) white and 204 (4%) Hispanic. Less than 520 (20%) of inmates knew all the routes of HIV transmission. A post-presentation test showed that 96% became aware of HIV/AIDS transmission and can better protect themselves. Skin infections caused by Staphylococcus aereus were reported and manifested clinically as pustules, cellulites, boils, carbuncles or impetigo. Though no systemic infection was involved, staphylococcal infections suggest lowered immunity, an indicator to undiagnosed HIV. This study purposefully provides HIV prevention education model for prison health educators. PMID:20191111

Cost savings threshold analysis of a capacity-building program for HIV prevention organizations.

Although the incidence of HIV each year remains steady, prevention funding is increasingly competitive. Programs need to justify costs in terms of evaluation outcomes, including economic ones. Threshold analyses set performance standards to determine program effectiveness relative to that threshold. This method was used to evaluate the potential cost savings of a national capacity-building program for HIV prevention organizations. Program costs were compared with the lifetime treatment costs of HIV, yielding an estimate of the HIV infections that would have to be prevented for the program to be cost saving. The 136 persons who completed the capacity-building program between 2000 and 2003 would have to avert 41 cases of HIV for the program to be considered cost saving. These figures represent less than one tenth of 1% of the 40,000 new HIV infections that occur in the United States annually and suggest a reasonable performance standard. These data underscore the resources needed to prevent HIV.

Persistent new HIV infections and risky behaviors underscore the need for enhanced HIV prevention. Social media interventions may promote safe sexual behaviors, increase HIV testing uptake, and promote safe injection behaviors. This review discusses how social media interventions tap into the wisdom of crowds through crowdsourcing, build peer-mentored communities, and deliver interventions through social networks. Social media HIV prevention interventions are constrained by ethical issues, low social media usage among some key populations, and implementation issues. Comprehensive measurement of social media interventions to prevent HIV is necessary, but requires further development of metrics. PMID:26516632

2015-01-01

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.

Cash transfers for HIV prevention: considering their potential.

2013-08-23

Cash payments to vulnerable households and/or individuals have increasingly garnered attention as a means to reduce poverty, improve health and achieve other development-related outcomes. Recent evidence from Malawi and Tanzania suggests that cash transfers can impact HIV-related behaviours and outcomes and, therefore, could serve as an important addition to HIV prevention efforts. This article reviews the current evidence on cash transfers for HIV prevention and suggests unresolved questions for further research. Gaps include (1) understanding more about the mechanisms and pathways through which cash transfers affect HIV-related outcomes; (2) addressing key operational questions, including the potential feasibility and the costs and benefits of different models of transfers and conditionality; and (3) evaluating and enhancing the wider impacts of cash transfers on health and development. Ongoing and future studies should build on current findings to unpack unresolved questions and to collect additional evidence on the multiple impacts of transfers in different settings. Furthermore, in order to address questions on sustainability, cash transfer programmes need to be integrated with other sectors and programmes that address structural factors such as education and programming to promote gender equality and address HIV.

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 article reviews the 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, treatment access, and outcomes. Social network analysis is a valuable 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, 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.

Incorporating Couples-Based Approaches into HIV Prevention for Gay and Bisexual Men: Opportunities and Challenges

Thirty years after the beginning of the HIV epidemic, gay, bisexual, and other men who have sex with men (collectively called MSM) bear a disproportionate burden of HIV in the United States and continue to acquire a distressingly high number and proportion of new infections. Historically, HIV prevention for MSM has been focused on individual-level behavior change, rarely intervening with MSM as part of a couple. Yet, an estimated 33–67% of HIV infections among MSM are acquired from primary sexual partners, suggesting that work with MSM as couples could be an important contributor to prevention. Given the emergence of high impact combination HIV prevention, it is timely to consider how work with the broad variety of male couples can improve both personal and community health. Couples HIV testing and counseling for MSM is an important advance for identifying men who are unaware that they are HIV-positive, identifying HIV-discordant couples, and supporting men who want to learn their HIV status with their partner. Once men know their HIV status, new advances in biomedical prevention, which can dramatically reduce risk of HIV transmission or acquisition, allow men to make prevention decisions that can protect themselves and their partners. This paper highlights the present-day challenges and benefits of using a couples-based approach with MSM in the era of combination prevention to increase knowledge of HIV status, increase identification of HIV discordant couples to improve targeting prevention services, and support mutual disclosure of HIV status.

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

Pre-exposure prophylaxis (PrEP), in combination with traditional prevention strategies (such as condom use, voluntary HIV counseling and testing, and treatment for sexually transmitted infections), has been shown to effectively prevent HIV infection. As of September 2015, the World Health Organization recommends that people at substantial risk of HIV infection should be offered PrEP as an additional prevention choice, as part of comprehensive prevention. This article introduces how to apply a systematic review using the methodology of Grading of Recommendations Assessment, Development and Evaluation (GRADE) to write clinical guidelines. With support from the Taiwan Centers for Disease Control, the Taiwan AIDS Society published clinical guidelines for oral pre-exposure prophylaxis in Taiwan. Nurses are responsible to apply evidence-based knowledge and to use their professional influence to shape health policies related to HIV prevention.

HIV/AIDS poses grave risk to human development in sub-Saharan Africa. Evidence-based interventions that are rooted in local culture could help efforts to prevent threats to human development from HIV/AIDS. We used concept mapping (Concept System, 2006 ) to construct the components and content of a locally developed HIV/AIDS curriculum for use by secondary schools in Lusaka, Zambia. Participants were school counsellors (n = 14), youth health program officers (n = 7), and regular education teachers (n = 3) from the education, health, and youth development agencies in Lusaka, Zambia (males = 11; females = 13; mean age 38; SD = 15 years). Concept mapping yielded six statement clusters defining preliminary components of a locally grounded in-school HIV/AIDS prevention curriculum and the content items that define these components: (1) life skills education (18 items), (2) sexuality and reproductive health (10 items), (3) treatment, care and support (13 items), (4) counselling (12 items), (5) basic facts about HIV/AIDS (11 items), and (6) dissemination of information about HIV/AIDS (11 items). Zambian locally constructed constructs for an HIV/STD prevention curriculum overlap those promoted by public health programs in the country and internationally.

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.

Multiple prevention measures have the possibility of impacting HIV incidence in South Korea, including early diagnosis, early treatment, and pre-exposure prophylaxis (PrEP). We investigated how each of these interventions could impact the local HIV epidemic, especially among men who have sex with men (MSM), who have become the major risk group in South Korea. A mathematical model was used to estimate the effects of each these interventions on the HIV epidemic in South Korea over the next 40 years, as compared to the current situation. We constructed a mathematical model of HIV infection among MSM in South Korea, dividing the MSM population into seven groups, and simulated the effects of early antiretroviral therapy (ART), early diagnosis, PrEP, and combination interventions on the incidence and prevalence of HIV infection, as compared to the current situation that would be expected without any new prevention measures. Overall, the model suggested that the most effective prevention measure would be PrEP. Even though PrEP effectiveness could be lessened by increased unsafe sex behavior, PrEP use was still more beneficial than the current situation. In the model, early diagnosis of HIV infection was also effectively decreased HIV incidence. However, early ART did not show considerable effectiveness. As expected, it would be most effective if all interventions (PrEP, early diagnosis and early treatment) were implemented together. This model suggests that PrEP and early diagnosis could be a very effective way to reduce HIV incidence in South Korea among MSM.

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 Justice and HIV Vaccine Research in the Age of Pre-Exposure Prophylaxis and Treatment as Prevention

PubMed Central

Bailey, Theodore C.; Sugarman, Jeremy

2014-01-01

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.

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.

Macro-Level Approaches to HIV Prevention Among Ethnic Minority Youth

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.

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.

The last few years have witnessed a renewed commitment to HIV prevention. The evidence to support the use of antiretroviral therapy (ART) for prevention of new HIV infection in the form of Pre-exposure prophylaxis (PrEP) among men who have sex with men, transgender, people who inject drugs, heterosexual men and women and HIV-1 serodiscordant couples, or treatment as prevention (TasP) for serodiscordant couples have also grown. The need to explore the possible use of ART for HIV prevention in Nigeria has become imperative in view of its high HIV burden and the current slow pace of effort to achieve the universal target of reducing its HIV incidence by 50%. While PrEP and TasP are welcome addendum to the existing HIV prevention armamentarium, it is still important to conduct a demonstration project to identify strategies that can facilitate access to PrEP and TasP taking cognizance of the peculiar local challenges with respect to ART and HIV prevention commodity access. The country has therefore drawn a roadmap for itself on how to introduce ART for use for HIV prevention as either PrEP or TasP. This paper discusses the three year national roadmap that would enable the country generated the needed scientific evidence as well as extensive community support for use of ART for HIV prevention in Nigeria. This process includes the conduct of modeling and formative studies, and the implementation of a 24 months demonstration project. The outcome of the demonstration project would inform plans for the scale up of pre-exposure prophylaxis (PrEP) access for population(s) at high risk for HIV infection in Nigeria.

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. 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. 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). Adolescents with the greatest structural deprivation are at higher risk of HIV, but social

The present formative study sought to describe issues relevant to HIV prevention among men who have sex with men (MSM) in South India by surveying 62 MSM outreach workers from three non governmental organizations in Chennai. Although 92% reported having sex with men, only 74% identified as gay and 27% were married. Only half of these men reported having been tested for HIV. More than half of the sample reported that they would rather not know they had HIV until they were sick, and almost half indicated that they would rather end their life than live with the disease. Eighty-five percent of the sample reported having experienced varying levels of harassment from police, and 86% reported varying levels of harassment from others. These data point to several important barriers to HIV prevention among MSM in South India and lay the groundwork for enhancing the use of outreach workers to play a role in HIV prevention in this population.

HIV among immigrants living in high-income countries: a realist review of evidence to guide targeted approaches to behavioural HIV prevention

PubMed Central

2012-01-01

Background Immigrants from developing and middle-income countries are an emerging priority in HIV prevention in high-income countries. This may be explained in part by accelerating international migration and population mobility. However, it may also be due to the vulnerabilities of immigrants including social exclusion along with socioeconomic, cultural and language barriers to HIV prevention. Contemporary thinking on effective HIV prevention stresses the need for targeted approaches that adapt HIV prevention interventions according to the cultural context and population being addressed. This review of evidence sought to generate insights into targeted approaches in this emerging area of HIV prevention. Methods We undertook a realist review to answer the research question: ‘How are HIV prevention interventions in high-income countries adapted to suit immigrants’ needs?’ A key goal was to uncover underlying theories or mechanisms operating in behavioural HIV prevention interventions with immigrants, to uncover explanations as how and why they work (or not) for particular groups in particular contexts, and thus to refine the underlying theories. The realist review mapped seven initial mechanisms underlying culturally appropriate HIV prevention with immigrants. Evidence from intervention studies and qualitative studies found in systematic searches was then used to test and refine these seven mechanisms. Results Thirty-four intervention studies and 40 qualitative studies contributed to the analysis and synthesis of evidence. The strongest evidence supported the role of ‘consonance’ mechanisms, indicating the pivotal need to incorporate cultural values into the intervention content. Moderate evidence was found to support the role of three other mechanisms – ‘understanding’, ‘specificity’ and ‘embeddedness’ – which indicated that using the language of immigrants, usually the ‘mother tongue’, targeting (in terms of ethnicity) and the use of

One of the four national HIV prevention goals is to incorporate combinations of effective, evidence-based approaches to prevent HIV infection. In fields of public health, techniques that alter environment and affect choice options are effective. Structural approaches may be effective in preventing HIV infection. Existing frameworks for structural interventions were lacking in breadth and/or depth. We conducted a systematic review and searched CDC’s HIV/AIDS Prevention Research Synthesis Project’s database for relevant interventions during 1988–2013. We used an iterative process to develop the taxonomy. We identified 213 structural interventions: Access (65%), Policy/Procedure (32%), Mass Media (29%), Physical Structure (27%), Capacity Building (24%), Community Mobilization (9%), and Social Determinants of Health (8%). Forty percent targeted high-risk populations (e.g., people who inject drugs [12%]). This paper describes a comprehensive, well-defined taxonomy of structural interventions with 7 categories and 20 subcategories. The taxonomy accommodated all interventions identified. PMID:29159594

Background Evidence linking violence against women and HIV has grown, including on the cycle of violence and the links between violence against children and women. To create an effective response to the HIV epidemic, it is key to prevent sexual violence against children and intimate partner violence (IPV) against adolescent girls. Methods Authors analyzed data from national household surveys on violence against children undertaken by governments in Swaziland, Tanzania, Kenya, and Zimbabwe, with support of the Together for Girls initiative, as well as an analysis of evidence on effective programmes. Results Data show that sexual and physical violence in childhood are linked to negative health outcomes, including increased sexual risk taking (eg, inconsistent condom use and increased number of sexual partners), and that girls begin experiencing IPV (emotional, physical, and sexual) during adolescence. Evidence on effective programmes addressing childhood sexual violence is growing. Key interventions focus on increasing knowledge among children and caregivers by addressing attitudes and practices around violence, including dating relationships. Programmes also seek to build awareness of services available for children who experience violence. Discussion Findings include incorporating attention to children into HIV and violence programmes directed to adults; increased coordination and leveraging of resources between these programmes; test transferability of programmes in low- and middle-income countries; and invest in data collection and robust evaluations of interventions to prevent sexual violence and IPV among children. Conclusions This article contributes to a growing body of evidence on the prevention of sexual violence and HIV in children. PMID:24918598

Faith-Based HIV Care and Prevention in Chinese Immigrant Communities: Rhetoric or Reality?

2012-01-01

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 the United States, black men who have sex with men (BMSM) are at highest risk for HIV infection and are at high risk for limited health service utilization. We describe HIV health center (HHC) affiliation network patterns and their potential determinants among urban BMSM. The Men's Assessment of Social and Risk Network instrument was used to elicit HHC utilization, as reported by study respondents recruited through respondent-driven sampling. In 2010, 204 BMSM were systematically recruited from diverse venues in Chicago, IL. A 2-mode data set was constructed that included study participants and 9 diverse HHCs. Associations between individual-level characteristics and HHC utilization were analyzed using Multiple Regression Quadratic Assignment Procedure. Visualization analyses included computation of HHC centrality and faction membership. High utilization of HHCs (45.9%-70.3%) was evident among BMSM, 44.4% who were HIV infected. Multiple Regression Quadratic Assignment Procedure revealed that age, social network size, and HIV status were associated with HHC affiliation patterns (coeff., 0.13-0.27; all P < 0.05). With the exception of one HHC, HHCs offering HIV prevention services to HIV-infected participants occupied peripheral positions within the network of health centers. High-risk HIV-uninfected participants affiliated most with an HHC that offers only treatment services. Subcategories of BMSM in this sample affiliated with HHCs that may not provide appropriate HIV prevention services. Using 2-mode data, public health authorities may be better able to match prevention services to BMSM need; in particular, HIV prevention services for high-risk HIV-uninfected men and HIV "prevention for positives" services for HIV-infected men.

HIV-related stigma has been shown to impede HIV-antibody testing and safer sexual practices in adults. Less is known about its effects on prevention programs among at-risk youth. This study examined the longitudinal relationships between HIV-stigma and HIV-knowledge following completion of a validated group-based intervention. Data were provided by 1,654 African-American adolescents who participated in a large multi-city prevention trial (Project iMPACCS). Participants were randomly assigned to an empirically-validated skill-based intervention or a general health promotion control group. Both stigma and knowledge were assessed at baseline and post-intervention. Results suggested that adolescents participating in the intervention showed improvements in knowledge and decreases in stigma when compared to controls. Improvements in stigma appeared to be partly driven by improvements in knowledge. Higher baseline stigma was shown to reduce gains in knowledge in both the treatment and control groups. Results suggest that HIV-stigma can interfere with how youth identify with and internalize messages from group-based prevention trials.

This work focuses on the use of antiretroviral agents to prevent the sexual transmission of HIV-1. Two randomized clinical trials demonstrated that antiretroviral agents provided before exposure to HIV-1 offer substantial protection, ostensibly directly proportional to the concentration of antiretroviral therapy (ART) in the genital secretions. Intense focus on the use of HIV treatment as prevention has led to publication of modeling exercises, ecological studies, and observational studies, most of which support the potential benefits of ART. However, the logistical requirements for successful use of ART for prevention are considerable. ART will serve as a cornerstone of combination prevention of HIV-1. Continued research will be essential to measure anticipated benefits and to detect implementation barriers and untoward consequences of such a program, especially increases in primary ART resistance.

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.

Pre-exposure prophylaxis for HIV prevention in women: current perspectives

There are ~900,000 new HIV infections among women every year, representing nearly half of all new HIV infections globally. In the US, nearly one-fifth of all new HIV infections occur among women, and women from racial and ethnic minority communities experience disproportionately high rates of new HIV infections. Thus, there is a need to develop and implement effective HIV prevention strategies for women in the US and internationally, with a specific need to advance strategies in minority communities. Previous studies have demonstrated that oral HIV pre-exposure prophylaxis (PrEP), the use of antiretroviral medications by HIV-uninfected persons to prevent HIV acquisition, can reduce HIV incidence among women who are adherent to PrEP. However, to date, awareness and uptake of PrEP among women have been very limited, suggesting a need for innovative strategies to increase the knowledge of and access to PrEP among women in diverse settings. This narrative review summarizes the efficacy and safety data of PrEP in women, discusses considerations related to medication adherence for women who use PrEP, and highlights behavioral, social, and structural barriers to maximize the effectiveness of PrEP in women. It also reviews novel modalities for PrEP in women which are being developed and tested, including topical formulations and long-acting injectable agents that may offer advantages as compared to oral PrEP and proposes a community-oriented, social networking framework to increase awareness of PrEP among women. If women are provided with access to PrEP and support to overcome social and structural barriers to adhere to PrEP, this prevention strategy holds great promise to impact the HIV epidemic among women in the US and globally.

Male-to-female transgender individuals, or transgender women (TW), are at high risk for HIV infection and face multiple barriers to HIV care. Advocates agree that numerous factors need to be addressed concurrently to prevent HIV infection in TW, including primary health care. This article examines how a community-based clinic that offers free or low-cost care addresses the health care needs of TW. A total of 20 TW who attended a health care clinic dedicated to community-based health were interviewed regarding best practices for HIV prevention and primary care. In-depth interviews were conducted, transcribed, coded, and analyzed. Factors reported to be effective for HIV prevention and primary care included (a) access to health care in settings not dedicated to serving transgender and/or gay communities, (b) a friendly atmosphere and staff sensitivity, and (c) holistic care including hormone therapy. Community-based health care settings can be ideal locales for HIV prevention and primary care for TW. PMID:19732697

This article describes the influence of a peer education programme on skills development among 22 women participating in HIV prevention trials. Interviews were used to collect data on peer educator experiences and their opinions of the trainings. The training enhanced their agency and confidence to engage their family and community on health promotion, including HIV prevention research procedures, thus improving their self-esteem and communication skills. Training and partnering with clinical trial participants as peer educators is an effective and sustainable community-based approach for HIV prevention.

Despite the need for targeted HIV prevention interventions for prison inmates, institutional and access barriers have impeded development and evaluation of such programs. Over the past 6 years, the authors have developed a unique collaborative relationship to develop and evaluate HIV prevention interventions for prison inmates. The collaboration includes an academic research institution (the Center for AIDS Prevention Studies at the University of California, San Francisco), a community-based organization (Centerforce), and the staff and inmate peer educators inside a state prison. In this ongoing collaboration, the authors have developed and evaluated a series of HIV prevention interventions for prison inmates and for women who visit prison inmates. Results of these studies support the feasibility and effectiveness of HIV prevention programs for inmates and their partners both in prison and in the community. Access and institutional barriers to HIV intervention research in prisons can be overcome through the development of collaborative research partnerships.

A novel, bottom-up approach to promote evidence-based HIV prevention for people who inject drugs in Ukraine: protocol for the MICT (‘Bridge’) HIV prevention exchange project

PubMed Central

2014-01-01

Background Ukraine has one of the most severe HIV epidemics in Eastern Europe, with an estimated 1.6% of the adult population living with the virus. Injection drug use accounts for 36% of new HIV cases. Nongovernmental organizations in Ukraine have little experience with effective, theory-based behavioral risk reduction interventions necessary to reduce the scope of the HIV epidemic among Ukrainians who inject drugs. This study seeks to promote the use of evidence-based HIV prevention strategies among Ukrainian organizations working with drug users. Methods/design This study combines qualitative and quantitative methods to explore a model of HIV prevention intervention development and implementation that disseminates common factors of effective behavioral risk reduction interventions and enables service providers to develop programs that reflect their specific organizational contexts. Eight agencies, located in regions of Ukraine with the highest HIV and drug use rates and selected to represent key organizational context criteria (e.g., agency size, target population, experience with HIV prevention), will be taught common factors as the basis for intervention development. We will use qualitative methods, including interviews and observations, to document the process of intervention development and implementation at each agency. Using risk assessments with intervention participants, we will also assess intervention effectiveness. The primary outcome analyses will determine the extent to which agencies develop and implement an intervention for drug users that incorporates common factors of effective behavioral interventions. Effectiveness analyses will be conducted, and effect size of each intervention will be compared to that of published HIV prevention interventions for drug users with demonstrated effectiveness. This study will explore the role of organizational context on intervention development and implementation, including resource allocation decisions

Considerations in HIV Prevention for Women Affected by the Criminal Justice System

Within the national dialogue of HIV prevention strategies, relatively little consideration is given to the millions of women and girls affected by the criminal justice system either through their own incarceration or that of their partners. Yet statistics indicate that these women and girls are disproportionately infected or at risk for HIV and other sexually transmitted infections and much of this risk is directly related to the dynamics and circumstances that led to their incarceration or relationships with incarcerated men. As we look for the link between public health and correctional health within our National HIV/AIDS Strategy, it is imperative that the risks, obstacles, and opportunities facing women and girls affected by incarceration are brought into the discussion. Gender responsive HIV prevention policies and practices must be developed to address the unique risks and opportunities for these women and girls. This paper presents data on HIV risk and other health issues specific to this community of women and girls, discusses key factors for consideration when developing gender-responsive HIV strategies for these communities, and makes recommendations for inclusion in the National HIV/AIDS Strategy and other state and local HIV prevention efforts.

India has the greatest number of HIV infections in Asia and the third highest total number of infected persons globally. Men who have sex with men (MSM) are considered by the Government of India's National AIDS Control Organization (NACO) a "core risk group" for HIV in need of HIV prevention efforts. However there is a dearth of information on the frequency of participation in HIV prevention interventions and subsequent HIV risk and other correlates among MSM in India. Recruited through peer outreach workers, word of mouth and snowball sampling techniques, 210 MSM in Chennai completed an interviewer-administered assessment, including questions about participating in any HIV prevention interventions in the past year, sexual risk taking, demographics, MSM identities, and other psychosocial variables. Bivariate and multivariable logistic regression procedures were used to examine behavioral and demographic correlates with HIV prevention intervention participation. More than a quarter (26%) of the sample reported participating in an HIV prevention intervention in the year prior to study participation. Participants who reported engaging in unprotected anal sex (UAS; odds ratio [OR] = 0.28; p = 0.01) in the 3 months prior to study enrollment were less likely to have participated in an HIV prevention program in the past year. MSM who were older (OR = 1.04; p = 0.05), kothis (feminine acting/appearing and predominantly receptive partners in anal sex) compared to panthis (masculine appearing, predominantly insertive partners; OR = 5.52, p = 0.0004), those with higher educational attainment (OR = 1.48, p = 0.01), being "out" about having sex with other men (OR = 4.03, p = 0.0001), and MSM who reported ever having been paid in exchange for sex (OR = 2.92, p = 0.001) were more likely to have reported participation in an HIV prevention intervention in the preceding year. In a multivariable model, MSM reporting UAS in the prior 3 months were less likely to have participated in

We developed a pragmatic modelling approach to estimate the impact of treatment as prevention (TasP); outreach testing strategies; and pre-exposure prophylaxis (PrEP) on the epidemiology of HIV and its associated pharmaceutical expenses. Our model estimates the incremental health (in terms of new HIV diagnoses) and budget impact of two prevention scenarios (outreach+TasP and outreach+TasP+PrEP) against a 'no additional prevention' scenario. Model parameters were estimated from reported Belgian epidemiology and literature data. The analysis was performed from a healthcare payer perspective with a 15-year-time horizon. It considers subpopulation differences, HIV infections diagnosed in Belgium having occurred prior to migration, and the effects of an ageing HIV population. Without additional prevention measures, the annual number of new HIV diagnoses rises to over 1350 new diagnoses in 2030 as compared to baseline, resulting in a budget expenditure of €260.5 million. Implementation of outreach+TasP and outreach+TasP+PrEP results in a decrease in the number of new HIV diagnoses to 865 and 663 per year, respectively. Respective budget impacts decrease by €20.6 million and €33.7 million. Foregoing additional investments in prevention is not an option. An approach combining TasP, outreach and PrEP is most effective in reducing the number of new HIV diagnoses and the HIV treatment budget. Our model is the first pragmatic HIV model in Belgium estimating the consequences of a combined preventive approach on the HIV epidemiology and its economic burden assuming other prevention efforts such as condom use and harm reduction strategies remain the same.

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. 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. 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. 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. 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. © 2014 Sigma Theta Tau International.

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.

HIV prevention during pregnancy and lactation is critical for both maternal and child health. Pregnancy provides a critical opportunity for clinicians to elicit women's vulnerabilities to HIV and offer HIV testing, treatment and referral and/or comprehensive HIV prevention options for the current pregnancy, the postpartum period and safer conception options for future pregnancies. In this commentary, we review the safety of oral pre-exposure prophylaxis with tenofovir/emtricitabine in pregnant and lactating women and suggest opportunities to identify pregnant and postpartum women at substantial risk of HIV. We then describe a clinical approach to caring for women who both choose and decline pre-exposure prophylaxis during pregnancy and postpartum, highlighting areas for future research. Evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine is safe in pregnancy and lactation. Identifying women vulnerable to HIV and eligible for pre-exposure prophylaxis is challenging in light of the myriad of individual, community, and structural forces impacting HIV acquisition. Validated risk calculators exist for specific populations but have not been used to screen and offer HIV prevention methods. Partner testing and engagement of men living with HIV are additional means of reaching at-risk women. However, women's vulnerabilities to HIV change over time. Combining screening for HIV vulnerability with HIV and/or STI testing at standard intervals during pregnancy is a practical way to prompt providers to incorporate HIV screening and prevention counselling. We suggest using shared decision-making to offer women pre-exposure prophylaxis as one of multiple HIV prevention strategies during pregnancy and postpartum, facilitating open conversations about HIV vulnerabilities, preferences about HIV prevention strategies, and choosing a method that best meets the needs of each woman. Growing evidence suggests that pre-exposure prophylaxis with tenofovir

There is growing optimism in the global health community that the HIV epidemic can be halted. After decades of relying primarily on behavior change to prevent HIV transmission, a second generation of prevention efforts based on medical or biological interventions such as male circumcision and preexposure prophylaxis--the use of antiretroviral drugs to protect uninfected, at-risk individuals--has shown promising results. This article calls for a third generation of HIV prevention efforts that would integrate behavioral, biological, and structural interventions focused on the social, political, and environmental underpinnings of the epidemic, making use of local epidemiological evidence to target affected populations. In this third wave, global programs should deliver HIV prevention services together with cost-effective interventions for reproductive health and for tuberculosis, malaria, and other diseases. Additionally, new efforts are needed to address gaps in HIV prevention research, evaluation, and implementation. Increased and sustained funding, along with evidence-based allocation of funds, will be necessary to accelerate the decline in new HIV infections.

Preferences for a Mobile HIV Prevention App for Men Who Have Sex With Men.

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. 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. 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. 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 important factors in men's willingness to

When HIV prevention targets risk and vulnerability, it focuses on individual agency and social structures, ignoring the centrality of community in effective HIV prevention. The neoliberal concept of risk assumes individuals are rational agents who act on information provided to them regarding HIV transmission. This individualistic framework does not recognize the communities in which people act and connect. The concept of vulnerability on the other hand acknowledges the social world, but mainly as social barriers that make it difficult for individuals to act. Neither approach to HIV prevention offers understanding of community practices or collective agency, both central to success in HIV prevention to date. Drawing on examples of the social transformation achieved by community action in Australia and Brazil, this article focuses on this middle ground and its role in effective HIV prevention.

Misconceptions about HIV transmission and prevention may inhibit individuals' accurate assessment of their level of risk. We used venue-based sampling to conduct a cross-sectional study of heterosexually active adults (N = 1,221) within areas exhibiting high poverty and HIV/AIDS rates in Miami-Dade and Broward counties in 2007. Two logistic regression analyses identified correlates of holding inaccurate beliefs about HIV transmission and prevention. Belief in incorrect HIV prevention methods (27.2%) and modes of transmission (38.5%) was common. Having at least one incorrect prevention belief was associated with being Hispanic compared to white (non-Hispanic), being depressed, and not knowing one's HIV status. Having at least one incorrect transmission belief was associated with being younger, heavy alcohol use, being depressed, not having seen a physician in the past 12 months, and not knowing one's HIV status. Among low-income heterosexuals, HIV prevention and transmission myths are widespread. Debunking them could have HIV prevention value.

Background Efforts at HIV prevention that focus on high risk places might be more effective and less stigmatizing than those targeting high risk groups. The objective of the present study was to assess risk behaviour patterns, signs of current preventive interventions and apparent gaps in places where the risk of HIV transmission is high and in communities with high HIV prevalence. Methods The PLACE method was used to collect data. Inhabitants of selected communities in Lusaka and Livingstone were interviewed about where people met new sexual partners. Signs of HIV preventive activities in these places were recorded. At selected venues, people were interviewed about their sexual behaviour. Peer educators and staff of NGOs were also interviewed. Results The places identified were mostly bars, restaurants or sherbeens, and fewer than 20% reported any HIV preventive activity such as meetings, pamphlets or posters. In 43% of places in Livingstone and 26% in Lusaka, condoms were never available. There were few active peer educators. Among the 432 persons in Lusaka and 676 in Livingstone who were invited for interview about sexual behaviour, consistent condom use was relatively high in Lusaka (77%) but low in Livingstone (44% of men and 34% of women). Having no condom available was the most common reason for not using one. Condom use in Livingstone was higher among individuals socializing in places where condoms always were available. Conclusion In the places studied we found a high prevalence of behaviours with a high potential for HIV transmission but few signs of HIV preventive interventions. Covering the gaps in prevention in these high exposure places should be given the highest priority. PMID:18218124

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.

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.

The current dominant model of HIV prevention intervention dissemination involves packaging interventions developed in one context, training providers to implement that specific intervention, and evaluating the extent to which providers implement it with fidelity. Research shows that providers rarely implement these programs with fidelity due to perceived incompatibility, resource constraints, and preference for locally generated solutions. In this study, we used the concept of "common factors," or broad constructs shared by most evidence-based HIV prevention interventions, to train service providers to develop their own programs. We recruited eight Ukrainian HIV prevention organizations from regions with HIV epidemics concentrated among people who inject drugs. We trained staff to identify HIV risk behaviors and determinants, construct behavior change logic models, and develop and manualize an intervention. We systematically reviewed each manual to assess intervention format and content and determine whether the program met intervention criteria as taught during training. All agencies developed programs that reflected common factors of effective behavior change HIV prevention interventions. Each agency's program targeted a unique population that reflected local HIV epidemiology. All programs incorporated diverse pedagogical strategies that focused on skill-building, goal-setting, communication, and empowerment. Agencies struggled to limit information dissemination and the overall scope and length of their programs. We conclude that training service providers to develop their own programs based on common elements of effective behavior change interventions can potentially transform existing processes of program development, implementation, and capacity building. Expanding this model will require committed training and support resources. © 2015 Society for Public Health Education.

HIV PREVENTION FOR MIGRANTS IN TRANSIT: DEVELOPING AND TESTING TRAIN

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

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.

Globally, 150,000 new paediatric human immunodeficiency virus type 1 (HIV-1) infections occurred in 2015. There remain complex challenges to the global elimination of paediatric HIV-1 infection. Thus, for the global community to achieve elimination of new paediatric HIV-1 infections, innovative approaches need to be explored. Immune-based approaches to prevention of mother-to-child transmission (MTCT) may help fill some of the remaining gaps and provide new opportunities to achieve an AIDS-free generation. Immune-based interventions to prevent MTCT of HIV-1 may include paediatric HIV vaccines and passive immunization approaches. Recent discoveries providing evidence of robust immune responses to HIV in infants open new and exciting prospects for paediatric HIV vaccines. Moreover, successful vaccination of infants has a different set of requirements than vaccination of adults and may be easier to achieve. Proof-of-concept has been established over the last two decades that passively administered HIV-1 Env-specific monoclonal antibody (mAbs) can prevent chimeric simian human immunodeficiency virus (SHIV) transmission to newborn nonhuman primates. There has been tremendous progress in isolating and characterizing broadly neutralizing antibodies to HIV, and clinical testing of these antibodies for treatment and prevention in both infants and adults is a major effort in the field. Immune-based interventions need to be actively explored as they can provide critically important tools to address persistent challenges in MTCT prevention. It is a pivotal time for the field with active discussions on the best strategy to further reduce HIV infection of infants and accomplish the World Health Organization Fast-Track 2030 goals to eliminate new paediatric HIV infections. © 2017 The Authors.

Social development of commercial sex workers in India: an essential step in HIV/AIDS prevention.

PubMed

Chattopadhyay, Amit; McKaig, Rosemary G

2004-03-01

India has the highest number of HIV/AIDS cases in the world. Current HIV/AIDS prevention strategies are based on regular and appropriate condom use. However, most commercial sex workers (CSWs), who form the core/high-risk groups toward whom the prevention strategy is directed, are disempowered and socioeconomically marginalized. This does not allow them to insist on condom use by the client, especially in absence of governmental structural support. This paper discusses HIV/AIDS prevention issues that relate to CSWs in India; issues that play a vital role in initiation, perpetuation, and expansion of economic activity of CSWs; and those factors that influence the HIV/AIDS preventive practices of CSWs. This paper argues that CSWs can be empowered and emancipated; that HIV/AIDS control and prevention efforts in India must recognize that ad hoc promotion of condom use or similar such programs will not be effective to control HIV/AIDS; and that more extensive developmental work aimed at betterment of living conditions of CSWs is required for effective HIV/AIDS prevention.

Background Characterization of viruses in HIV-1 transmission pairs will help identify biological determinants of infectiousness and evaluate candidate interventions to reduce transmission. Although HIV-1 sequencing is frequently used to substantiate linkage between newly HIV-1 infected individuals and their sexual partners in epidemiologic and forensic studies, viral sequencing is seldom applied in HIV-1 prevention trials. The Partners in Prevention HSV/HIV Transmission Study (ClinicalTrials.gov #NCT00194519) was a prospective randomized placebo-controlled trial that enrolled serodiscordant heterosexual couples to determine the efficacy of genital herpes suppression in reducing HIV-1 transmission; as part of the study analysis, HIV-1 sequences were examined for genetic linkage between seroconverters and their enrolled partners. Methodology/Principal Findings We obtained partial consensus HIV-1 env and gag sequences from blood plasma for 151 transmission pairs and performed deep sequencing of env in some cases. We analyzed sequences with phylogenetic techniques and developed a Bayesian algorithm to evaluate the probability of linkage. For linkage, we required monophyletic clustering between enrolled partners' sequences and a Bayesian posterior probability of ≥50%. Adjudicators classified each seroconversion, finding 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) indeterminate transmissions, with linkage determined by consensus env sequencing in 91 (84%). Male seroconverters had a higher frequency of unlinked transmissions than female seroconverters. The likelihood of transmission from the enrolled partner was related to time on study, with increasing numbers of unlinked transmissions occurring after longer observation periods. Finally, baseline viral load was found to be significantly higher among linked transmitters. Conclusions/Significance In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of

Abstract Most U.S. investigators in the HIV Prevention Trials Network (HPTN) have been of majority race/ethnicity and sexual orientation. Research participants, in contrast, have been disproportionately from racial/ethnic minorities and men who have sex with men (MSM), reflecting the U.S. epidemic. We initiated and subsequently evaluated the HPTN Scholars Program that mentors early career investigators from underrepresented minority groups. Scholars were affiliated with the HPTN for 12–18 months, mentored by a senior researcher to analyze HPTN study data. Participation in scientific committees, trainings, protocol teams, and advisory groups was facilitated, followed by evaluative exit surveys. Twenty-six trainees have produced 17 peer-reviewed articles to date. Research topics typically explored health disparities and HIV prevention among black and Hispanic MSM and at-risk black women. Most scholars (81% in the first five cohorts) continued HIV research after program completion. Alumni reported program-related career benefits and subsequent funding successes. Their feedback also suggested that we must improve the scholars' abilities to engage new research protocols that are developed within the network. Mentored engagement can nurture the professional development of young researchers from racial/ethnic and sexual minority communities. Minority scientists can benefit from training and mentoring within research consortia, whereas the network research benefits from perspectives of underrepresented minority scientists. PMID:29145745

The purpose of this study is to understand (a) the experience of men viewing the film Women's Voices Women's Lives (WVWL), a prevention education film for and by heterosexual African American women living with HIV/AIDS in the United States, and (b) the perceived needs of male viewers on how to best access effective HIV/AIDS prevention messages. A postviewing structured written survey was completed addressing the experience of viewing the film and HIV prevention services in the community, respectively (N = 16). Responses include stunning realization and anger that motivated viewers to get immediately screened for HIV. In addition, the men felt they were informed about HIV risk through the courage and candidness of the women describing their experience. Participants reported that a film similar to WVWL should be made for heterosexual/bisexual men. The authors conclude film prevention messages are a powerful means to convey health education ideas.

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 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 YMSMS. 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. PMID:27244188

South African women who live in informal settlement communities are at high risk of HIV/AIDS infection due to their poor economic and social status. Prevention programs must include methods for improving their social conditions as well as their sexual risk behaviors. Members of Partners trained 24 women from informal settlements to lead HIV/AIDS education workshops for 480 residents. When these participants reached out to their neighbors, this participatory community-based approach resulted in providing HIV/AIDS prevention messages to more than 1,440 residents. Program leaders from three settlements said in focus group discussions that results from this social influences peer led approach demonstrated that women residents are a valuable resource in providing effective HIV/AIDS prevention programs to South Africa's most vulnerable residents.

HIV (human immunodeficiency virus) testing and prevention in the cruise industry.

There are no internationally recognized guidelines regarding HIV for employees on cruise ships. The aim of the study was to survey and compare current practices for crews in the cruise industry regarding HIV testing and prevention. Medical representatives from cruise companies were invited to complete a questionnaire on their company's practices regarding HIV-related issues. Fifteen of 18 invited representatives completed the questionnaire on behalf of 24 companies with a total of 155 ships. All 8 companies with a medical department had a written HIV policy, versus 4 of 16 companies that handled medical crew issues through independent medical consultant services. Thirteen companies required pre-sea HIV testing, 12 had a written HIV policy regarding HIV testing and prevention, and 18 had free condoms for the crew. A positive HIV test would result in revocation of the employment offer from 5 companies and in another 6 companies establish HIV as a pre-existing condition. Eight companies required HIV+ seafarers to demonstrate stability at regular intervals as a condition for sailing. Cruise companies have different practices regarding HIV in crew. Large cruise lines with medical departments are more likely to have a written HIV policy than companies using independent medical consultants. About half the companies required pre-sea HIV testing; some to avoid hiring HIV+ seafarers, others to establish HIV as a pre-existing condition or to ensure proper follow-up of their HIV+ seafarers. This report may provide input for company discussions about present or future HIV policies.

Abstract India has the greatest number of HIV infections in Asia and the third highest total number of infected persons globally. Men who have sex with men (MSM) are considered by the Government of India's National AIDS Control Organization (NACO) a “core risk group” for HIV in need of HIV prevention efforts. However there is a dearth of information on the frequency of participation in HIV prevention interventions and subsequent HIV risk and other correlates among MSM in India. Recruited through peer outreach workers, word of mouth and snowball sampling techniques, 210 MSM in Chennai completed an interviewer-administered assessment, including questions about participating in any HIV prevention interventions in the past year, sexual risk taking, demographics, MSM identities, and other psychosocial variables. Bivariate and multivariable logistic regression procedures were used to examine behavioral and demographic correlates with HIV prevention intervention participation. More than a quarter (26%) of the sample reported participating in an HIV prevention intervention in the year prior to study participation. Participants who reported engaging in unprotected anal sex (UAS; odds ratio [OR] = 0.28; p = 0.01) in the 3 months prior to study enrollment were less likely to have participated in an HIV prevention program in the past year. MSM who were older (OR = 1.04; p = 0.05), kothis (feminine acting/appearing and predominantly receptive partners in anal sex) compared to panthis (masculine appearing, predominantly insertive partners; OR = 5.52, p = 0.0004), those with higher educational attainment (OR = 1.48, p = 0.01), being “out” about having sex with other men (OR = 4.03, p = 0.0001), and MSM who reported ever having been paid in exchange for sex (OR = 2.92, p = 0.001) were more likely to have reported participation in an HIV prevention intervention in the preceding year. In a multivariable model, MSM reporting UAS

For women at risk of HIV-1, effective contraception and effective HIV-1 prevention are global priorities. In a clinical trial of pre-exposure prophylaxis (PrEP) for HIV-1 prevention in HIV-1-serodiscordant couples, we estimated the effectiveness of hormonal contraceptives (oral contraceptive pills, injectable depot medroxyprogesterone acetate, and hormonal implants) for pregnancy prevention relative to no contraception among 1785 HIV-1-uninfected women followed up to 36 months. We compared the effectiveness of each method among women assigned PrEP versus placebo. Contraception was not required for participation, but was offered on-site and was recorded monthly; incident pregnancy was determined by monthly urine testing. For women using no contraception, overall pregnancy incidence was 15.4% per year. Women reporting oral contraceptive use had comparable pregnancy incidence to women using no contraception, and this lack of contraceptive effectiveness was similar for those assigned PrEP and placebo (17.7 and 10.0% incidence per year, respectively; P-value for difference in effect by PrEP use = 0.24). Women reporting injectable contraception had reduced pregnancy incidence compared to those reporting no contraception, which did not differ by arm (PrEP 5.1%, placebo 5.3% per year; P-value for difference = 0.47). Contraceptive effectiveness was highest among women using implants (pregnancy incidence <1% per year in both arms). PrEP had no adverse impact on hormonal contraceptive effectiveness for pregnancy prevention. As seen previously in similar populations, women reporting contraceptive pill use had little protection from pregnancy, possibly due to poor adherence. Injectable or implantable hormonal contraception and PrEP provide effective prevention for pregnancy and HIV-1.

Factors that influence utilisation of HIV/AIDS prevention methods among university students residing at a selected university campus.

2014-01-01

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 importance of HIV prevention messaging for orphaned youth in Zimbabwe.

Haney, Erica; Singh, Kavita

2012-01-01

The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Female adolescent orphans are particularly in jeopardy of contracting HIV due to disadvantages including extreme poverty, low education, and the absent of parental oversight which can lead to higher risk-taking sexual behaviors. By understanding where girls receive education about HIV and who they rely on for information, organizations can effectively modify existing programs to better target this at-risk population. For this study a household survey was conducted which included 216 orphans and 324 non-orphans (n=540), aged 12-17 years, in the resource-poor setting of Hwange District, Zimbabwe. The aims of this article were to examine the differences between orphans and non-orphans in HIV prevention message exposure, level of motivation for learning about HIV, and communication with caregivers about safe sex. The household survey revealed that younger orphans, aged 12-15 years, were more motivated to learn about HIV and had greater HIV messaging exposure in school than non-orphans. These exposure and differences in the levels of motivation between groups dissipated at older ages. Our research also discovered less caregiver communication among orphans than non-orphans. Our findings suggest that HIV programs targeting orphans need to do a better job at keeping older orphans interested in HIV prevention at a time when it matters most. Furthermore, intervention strategies that provide caregiver support are instrumental in effectively delivering prevention messages to girls at home.

Investments in community-based HIV prevention programs in Ontario over the past two and a half decades are assumed to have had an impact on the HIV epidemic, but they have never been systematically evaluated. To help close this knowledge gap, we conducted a macro-level evaluation of investment in Ontario HIV prevention programs from the payer perspective. Our results showed that, from 1987 to 2011, province-wide community-based programs helped to avert a total of 16,672 HIV infections, saving Ontario's health care system approximately $6.5 billion Canadian dollars (range 4.8-7.5B). We also showed that these community-based HIV programs were cost-saving: from 2005 to 2011, every dollar invested in these programs saved about $5. This study is an important first step in understanding the impact of investing in community-based HIV prevention programs in Ontario and recognizing the impact that these programs have had in reducing HIV infections and health care costs.

To develop a model for prioritizing economic sectors for HIV preventive intervention programs in the workplace. This study was undertaken in Karnataka state, India. A 3-stage survey process was undertaken. In the first stage, we reviewed secondary data available from various government departments, identified industries in the private sector with large workforces, and mapped their geographical distribution. In the second stage, an initial rapid risk assessment of industrial sectors was undertaken, using key-informant interviews conducted in relation to a number of enterprises, and in consultation with stakeholders. In the third stage, we used both quantitative (polling booth survey) and qualitative methods (key informant interviews, in-depth interviews, focus group discussions) to study high-risk sectors in-depth, and assessed the need and feasibility of HIV workplace intervention programs. The highest risk sectors were found to be mining, garment/textile, sugar, construction/infrastructure, and fishing industries. Workers in all sectors had at best partial knowledge about HIV/AIDS, coupled with common misconceptions about HIV transmission. There were intersector and intrasector variations in risk and vulnerability across different geographical locations and across different categories of workers. This has implications for the design and implementation of workplace intervention programs. There is tremendous scope for HIV preventive interventions in workplaces in India. Given the variation in HIV risk across economic sectors and limited available resources, there will be increased pressure to prioritize intervention efforts towards high-risk sectors. This study offers a model for rapidly assessing the risk level of economic sectors for HIV intervention programs.

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

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

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.

Abstract Introduction: HIV prevention during pregnancy and lactation is critical for both maternal and child health. Pregnancy provides a critical opportunity for clinicians to elicit women’s vulnerabilities to HIV and offer HIV testing, treatment and referral and/or comprehensive HIV prevention options for the current pregnancy, the postpartum period and safer conception options for future pregnancies. In this commentary, we review the safety of oral pre-exposure prophylaxis with tenofovir/emtricitabine in pregnant and lactating women and suggest opportunities to identify pregnant and postpartum women at substantial risk of HIV. We then describe a clinical approach to caring for women who both choose and decline pre-exposure prophylaxis during pregnancy and postpartum, highlighting areas for future research. Discussion: Evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine is safe in pregnancy and lactation. Identifying women vulnerable to HIV and eligible for pre-exposure prophylaxis is challenging in light of the myriad of individual, community, and structural forces impacting HIV acquisition. Validated risk calculators exist for specific populations but have not been used to screen and offer HIV prevention methods. Partner testing and engagement of men living with HIV are additional means of reaching at-risk women. However, women’s vulnerabilities to HIV change over time. Combining screening for HIV vulnerability with HIV and/or STI testing at standard intervals during pregnancy is a practical way to prompt providers to incorporate HIV screening and prevention counselling. We suggest using shared decision-making to offer women pre-exposure prophylaxis as one of multiple HIV prevention strategies during pregnancy and postpartum, facilitating open conversations about HIV vulnerabilities, preferences about HIV prevention strategies, and choosing a method that best meets the needs of each woman. Conclusion: Growing evidence suggests that

HIV screening has existed in numerous methods as an important part of HIV prevention efforts over the years. Premarital HIV testing for couples who wish to marry has been implemented in a number of regions, which often operate in a mandatory rather than voluntary basis and is considered a contentious issue, with viewpoints held in favour and against. One such region is Malaysia which has a policy of mandatory premarital HIV testing of prospective Muslim married couples. The purpose of this study is to understand stakeholders' views on premarital HIV testing given the Malaysian Islamic context. 35 in-depth face to face semi-structured interviews were undertaken with key stakeholder groups involved in HIV prevention policy in Malaysia, namely, officials from the Ministry of Health, religious leaders and people living with HIV. Participants were recruited from the Klang Valley area, from July to December 2013, using purposive sampling techniques. Inclusion criteria necessitated that participants were over the age of 18 and provided full consent. Interviews were audiotaped, followed a standardised topic guide, transcribed verbatim and analysed using a framework analysis. Participants identified pre-marital HIV testing as an effective HIV prevention policy implemented in Malaysia and was viewed, for the most part, as a positive initiative across all stakeholders. Religious leaders were supportive of testing as it provides a protective mechanism, in line with the teachings of the Shariah, while Ministry of Health officials considered it a normal part of their HIV prevention screening initiatives. However, there were concerns surrounding issues such as confidentiality, counselling and discrimination surrounding the test described by the PLHIV group. The findings of this study show that among the participants interviewed was strong support for mandatory premarital HIV testing, which could possibly expose the vulnerability to HIV, reluctance to test and other areas in the

This study aims to describe human immunodeficiency virus (HIV)-related knowledge and beliefs, as well as understanding attitudes towards masculinity in the context of HIV prevention, held among Chilean men. This study reports the qualitative findings of a sequential qualitative-quantitative mixed methodology study: Bringing men into HIV Prevention in Chile, NIH R01 TW007674-03. Twenty in-depth interviews using a qualitative, descriptive approach to elicit information for the study were conducted among men residing in two communities of low socio-economic status in Santiago, Chile. Content analysis of interviews revealed three main themes regarding machismo and how it relates to HIV: sexuality and machismo, the changing nature of machismo, and violence against women. Addressing HIV and intimate partner violence through developing education programs tailored to meet the needs of Chilean men are needed to include men in HIV prevention efforts. Specifically, incorporating ideas of what men consider healthy masculinity and working to destigmatize men who have sex with men are important steps in addressing the negative aspects of machismo. © 2016 Sigma Theta Tau International.

HIV prevention research has been facing increasing ethical and operational challenges. Factors influencing the design and conduct of HIV prevention trials include a rapidly changing evidence base, new biomedical prevention methods and modalities being tested, a large diversity of countries, sites and populations affected by HIV and participating in trials, and challenges of developing and making available products that will be feasible and affordable for at-risk populations. To discuss these challenges, a meeting, Ethical considerations around novel combination prevention modalities in HIV prevention and vaccine trials in resource-limited settings, was convened by NIH/NIAID/Division of AIDS on April 22-23, 2013. Several themes emerged from the meeting: (1) because of both trial design and ethical complexities, choosing prevention packages and designing combination prevention research trials will need to be evaluated on a case by case basis in different clinical trials, countries, and health systems; (2) multilevel stakeholder engagement from the beginning is vital to a fair and transparent process and also to designing ethical and relevant trials; (3) research should generally be responsive to a host country's needs, and sponsors and stakeholders should work together to address potential barriers to future access; and finally, (4) another meeting including a broader group of stakeholders is needed to address many of the outstanding ethical issues raised by this meeting. We offer an overview of the meeting and the key discussion points and recommendations to help guide the design and conduct of future HIV prevention and vaccine research in resource-limited settings.

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 take into account age, gender, HIV-related stigma, and context, including cultural norms, which offer opportunities to improve programmatic coverage, reach, and uptake.

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." 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. 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.

There is scarce information on prevention coverage and management of sexually transmitted infections (STIs) in people with HIV in resource-limited settings. Six hundred eighty nine sexually active people diagnosed with HIV ≥12 months before the study, including 110 men who have sex with men, 237 heterosexual men, and 342 women, were recruited from HIV support groups and hospitals in El Salvador and completed self-administered computer-assisted questionnaires and STI testing. Logistic models identified correlates of exposure to posttest counseling (POC) and subsequent prevention interventions (PIs). Past-year transmission risk factors included unprotected sex with noncommercial partners (28.7%), having multiple sex partners (76.4%), a casual sex partner (31.4%), selling (3.5%) and purchasing sex (6.4%), herpes simplex virus type 2 (86.3%), and treatable STIs (18.6%). Men who have sex with men reported more recent casual partners, sex work, and alcohol and drug use than other subgroups. POC (22.8%), PIs (31.3%), and access to advice and information regarding HIV at the point of HIV care (24.1%) were limited. Of subjects with past-year STI symptoms (N = 267), 44.1% had sought medical attention. In multivariate analysis, POC was negatively associated with multiple partners. PI was associated with self-initiated testing, treatable STIs, and female sex. Both outcomes were associated with HIV-related discrimination outside of the health services context. Coverage of POC, PIs, and treatment-seeking for STI symptoms was low among individuals with diagnosed HIV infection, although most were in regular contact with care and treatment. Prevention programs at testing and treatment sites should be intensified and should incorporate risk behavior screening to improve targeting.

The Ayoreo population constitutes one of Bolivia's most vulnerable ethnic groups in terms of HIV/AIDS. Being a woman, indigenous, and a sex worker signifies belonging to a high-risk group. The aim of this study is to explore the Ayoreo sex workers' and health agents' perceptions of HIV/AIDS prevention programs in order to identify variables that could influence their success or failure. This study used an ethnographic methodology that included participant observation and semistructured interviews. In the data collection, participant observation and semistructured interviews with sex workers and key informants were conducted. Three themes emerged from the inductive data analysis: health prevention efforts, cultural inadequacy of prevention programs, and the eventuality of interventions. We conclude that nursing can develop culturally-adequate HIV/AIDS prevention interventions and programs as well as promote health within these populations. © The Author(s) 2014.

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. 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. 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. The early initiation of ART led to a sustained decrease in genetically linked HIV-1

There is a growing recognition of the need to provide HIV/AIDS prevention and care to migrant workers. Social involvement, a type of social capital, is considered a 'critical enabler' of effective HIV/AIDS prevention. Designated participation in formal community groups by the government (e.g., political parties) and informal, voluntary local networks by NGOs (e.g., alumni association, cultural & sports club) play different roles in HIV prevention. The objective of this study is to assess the impact of different types of social organizations on HIV/AIDS prevention knowledge among migrant workers. A cross-sectional study of 758 migrants was conducted in Hefei, Anhui Province, China. Data were collected through a self-reported questionnaire. Logistic regression was used to assess associations between different social organizations and HIV/AIDS prevention. Migrants who participated in social organizations had a higher awareness of HIV/AIDS knowledge than migrants who do not participate in social organizations. Higher levels of HIV/AIDS knowledge is associated with positive HIV/AIDS behaviors for people who attended political parties (odds ratio [OR] = 3.49, 95% CI: 1.22-9.99). This effect is not significant for alumni association. For both political parties and alumni association members (OR = 0.19, 95% CI: 0.06-0.66, OR = 0.20, 95% CI: 0.08-0.61, respectively), people who exhibited higher levels of HIV/AIDS knowledge had more negative attitudes than those with less knowledge. Social organizations play an important role in improving HIV/AIDS knowledge and behavior in migrants, providing a great opportunity for HIV/AIDS prevention.

HIV/AIDS is one of the leading causes of illness and death in the United States with individuals between the ages of 13 and 19 years being especially vulnerable for infection. The purpose of this study was to examine the attitudes, perceptions, and instructional practices of high school health teachers toward teaching HIV prevention. A total of 800 surveys were sent to a national random sample of high school health teachers and 50% responded. There was almost complete agreement (99%) among respondents that HIV prevention instruction is needed. The factors that emerged as significantly influencing the attitudes and perceptions of high school health teachers about teaching HIV prevention were related to teacher preparation, training, and years of experience teaching health education. A state mandate requiring HIV prevention instruction was significantly associated with higher teacher efficacy expectations and more perceived benefits, but did not have a significant influence in relation to practices in the classroom. Characteristics of high school health teachers that were significantly related to attitudes, perceptions, and instructional practices included the instructor's age, sex, and race/ethnicity. High school health teachers who reported the least experience teaching health education had the least supportive attitudes, perceived the most barriers, and had the lowest efficacy and outcome expectations related to teaching about HIV prevention. Whereas these findings support the importance of teacher preparation and training, they also suggest that more recent college graduates may not be fully prepared to provide effective instruction in HIV prevention. © 2012, American School Health Association.

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. PMID:16389505

This paper examines how marital violence affects women's ability to protect themselves from HIV/AIDS. In-depth interviews (n = 48) and focus groups (n = 84, 3-7 per group) were conducted among men and women in two randomly selected slums of Chennai, India. The study showed that community gender norms tacitly sanction domestic violence that interferes with adopting HIV-preventive behaviors. Given the choice between the immediate threat of violence and the relatively hypothetical specter of HIV, women often resign themselves to sexual demands and indiscretions that may increase their risk of HIV acquisition. In conclusion, AIDS-prevention interventions must incorporate gender-related social contexts in settings where husbands strictly enforce their locus of control. HIV-prevention messages targeting men may effectively reduce women's exposure to HIV/AIDS.

The Roles of Technology in Primary HIV Prevention for Men Who Have Sex with Men.

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.

In light of the increasing rates of HIV infection in African Americans, it is essential that black faith leaders become more proactive in the fight against the epidemic. The study aim was to engage faith leaders in a sustainable partnership to increase community participation in preventive HIV vaccine clinical research while improving their access to and utilization of HIV/AIDS prevention services. Leadership Development Seminars were adapted for faith leaders in Rochester, NY, with topics ranging from the importance of preventive HIV vaccine research to social issues surrounding HIV/AIDs within a theological framework. Seminars were taught by field-specific experts from the black community and included the development of action plans to institute HIV preventive ministries. To assess the outcome of the Seminars, baseline and post-training surveys were administered and analyzed through paired sample t Tests and informal interviews. 19 faith leaders completed the intervention. In general, the majority of clergy felt that their understanding of HIV vaccine research and its goals had increased postintervention. A critical outcome was the subsequent formation of the Rochester Faith Collaborative by participating clergy seeking to sustain the collaborative and address the implementation of community action plans. Providing scientific HIV/AIDS knowledge within the context of clergy members' belief structure was an effective method for engaging black Church leaders in Rochester, NY. Collaborative efforts with various local institutions and community-based organizations were essential in building trust with the faith leaders, thereby building bridges for better understanding of HIV/AIDS prevention efforts, including HIV vaccine research.

Current antiretroviral therapy allows to achieve and sustain maximal suppression of HIV replication in most treated patients. As result, the life expectancy of HIV-infected persons has improved dramatically and is nowadays similar to that of the HIV-negative population. However, oral antiretrovirals have to be taken daily and indefinitely to avoid resumption of HIV replication and selection of drug resistance. Unfortunately, drug adherence is often suboptimal and tends to decline over time. Areas covered: New drugs, formulations and delivery systems are being developed for extended-release of antiretrovirals. At this time, intramuscular cabotegravir and rilpivirine, dapivirine vaginal rings and tenofovir alafenamide subdermal implants are the products in more advanced stages of clinical development. Their pharmacokinetics/dynamics and safety/efficacy are reviewed. Expert commentary: In the absence of eradicative therapy for individuals with HIV infection and protective vaccines for persons at risk, long-term antiretroviral therapy is the best approach for preventing disease progression in patients and halting transmissions, either as result of 'treatment as prevention' for HIV carriers or 'pre-exposure prophylaxis' for uninfected individuals at risk. In all these scenarios, the advent of long-acting antiretrovirals will expand options for overcoming the challenge of suboptimal drug adherence and reduce the burden of HIV infection.

Transgender women are the population most vulnerable to HIV in Latin America, with prevalence between 18 and 38%. Although the region has improved antiretroviral coverage, there is an urgent need to strengthen HIV prevention for key populations to meet regional targets set by governments. We conducted an assessment on the state of HIV prevention among transgender women in Latin America. We conducted a desk review of Global AIDS Response Progress Reports, national strategic plans, technical reports and peer-reviewed articles from 17 Latin American countries published through January 2015. The review was preceded by 12 semi-structured interviews with UNAIDS and Pan American Health Organization officers and a discussion group with transgender women regional leaders, to guide the identification of documents. We assessed access to, implementation and coverage of programmes; legal frameworks; community participation; inclusion of new strategies; and alignment with international recommendations. Overall, prevention activities in the region focus on condom distribution, diagnosis of sexually transmitted infections and peer education, mostly delivered at health facilities, with limited community involvement. Argentina and Uruguay have implemented structural interventions to address social inclusion. Argentina, Brazil and Mexico have adopted early initiation of antiretroviral therapy and treatment as prevention strategies. The other countries do not have substantial tailored interventions and consider the trans population a sub-population of men who have sex with men in data collection and programme implementation. Limited coverage of services, discrimination and a deep-seated mistrust of the health system among transgender women are the main barriers to accessing HIV prevention services. Promising interventions include health services adapted to transgender women in Mexico; LGBT-friendly clinics in Argentina that incorporate community and health workers in mixed teams; task

Efforts to prevent HIV transmission among substance-using populations have focused primarily among injection drug users, which have produced measurable reductions in HIV incidence and prevalence. By contrast, the majority of substances used worldwide are administered by noninjectable means, and there is a dearth of HIV prevention interventions that target noninjecting substance users. Increased surveillance of trends in substance use, especially cocaine (including crack) and methamphetamine, in addition to new and emerging substances (eg, synthetic cannabinoids, cathinones, and other amphetamine analogs) are needed to develop and scale up effective and robust interventions for populations at risk for HIV transmission via sexual behaviors related to noninjection substance use. Strategies are needed that address unique challenges to HIV prevention for substance users who are HIV infected and those who are HIV uninfected and are at high risk. We propose a research agenda that prioritizes (1) combination HIV-prevention strategies in substance users; (2) behavioral HIV prevention programs that reduce sexual transmission behaviors in nontreatment seeking individuals; (3) medical and/or behavioral treatments for substance abuse that reduce/eliminate substance-related sexual transmission behaviors; and (4) structural interventions to reduce HIV incidence.

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 importance of HIV prevention messaging for orphaned youth in Zimbabwe

2014-01-01

The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Female adolescent orphans are particularly in jeopardy of contracting HIV due to disadvantages including extreme poverty, low education, and the absent of parental oversight which can lead to higher risk-taking sexual behaviors. By understanding where girls receive education about HIV and who they rely on for information, organizations can effectively modify existing programs to better target this at-risk population. For this study a household survey was conducted which included 216 orphans and 324 non-orphans (n=540), aged 12–17 years old, in the resource-poor setting of Hwange District, Zimbabwe. The aims of this paper were to examine the differences between orphans and non-orphans in HIV prevention message exposure, level of motivation for learning about HIV, and communication with caregivers about safe sex. The household survey revealed that younger orphans, aged 12–15 years old, were more motivated to learn about HIV and had greater HIV messaging exposure in school than non-orphans. These exposure and differences in the levels of motivation between groups dissipated at older ages. Our research also discovered less caregiver communication among orphans than non-orphans. Our findings suggest that HIV programs targeting orphans need to do a better job at keeping older orphans interested in HIV prevention at a time when it matters most. Furthermore, intervention strategies that provide caregiver support are instrumental in effectively delivering prevention messages to girls at home. PMID:22293040

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.

Introduction In 2010, two global networks of people living with HIV, the International Community of Women Living with HIV (ICW Global) and the Global Network of People living with HIV (GNP + ) were invited to review a draft strategic framework for the global scale up of prevention of vertical transmission (PVT) through the primary prevention of HIV and the prevention of unintended pregnancies among women living with HIV. In order to ensure recommendations were based on expressed needs of people living with HIV, GNP+ and ICW Global undertook a consultation amongst people living with HIV which highlighted both facilitators and barriers to prevention services. This commentary summarizes the results of that consultation. Discussion The consultation was comprised of an online consultation (moderated chat-forum with 36 participants from 16 countries), an anonymous online e-survey (601 respondents from 58 countries), and focus-group discussions with people living with HIV in Jamaica (27 participants). The consultation highlighted the discrepancies across regions with respect to access to essential packages of PVT services. However, the consultation participants also identified common barriers to access, including a lack of trustworthy sources of information, service providers’ attitudes, and gender-based violence. In addition, participant responses revealed common facilitators of access, including quality counselling on reproductive choices, male involvement, and decentralized services. Conclusions The consultation provided some understanding and insight into the participants’ experiences with and recommendations for PVT strategies. Participants agreed that successful, comprehensive PVT programming require greater efforts to both prevent primary HIV infection among young women and girls and, in particular, targeted efforts to ensure that women living with HIV and their partners are supported to avoid unintended pregnancies and to have safe, healthy pregnancies instead

The aims of the study were to elicit the perceptions of young people in Tanzania on the role of fear appeals in HIV-prevention messages and to identify important contextual factors that may influence young people's perceptions of HIV-prevention posters. A total of 10 focus groups were conducted to investigate the role of fear appeals using the extended parallel process model (EPPM) as a guide. Young people were shown a series of images (mostly posters) with alternating high and low-threat messages (fear appeals), and then asked questions about their overall beliefs about HIV and AIDS, as well as about their response in terms of perceived susceptibility to HIV infection, the severity of the message, and their perceptions of self-efficacy and response efficacy. The images and messages that specifically targeted young people were highest in inducing perceived susceptibility to HIV infection, while pictorial descriptions of the physical consequences of HIV infection and those messages related to the stigma and discrimination faced by HIV-infected or affected people induced greater perceptions of severity. The information-based posters rated high in inducing response efficacy, while none of the images seemed to convince young people that they had the self-efficacy to perform the recommended health behaviours. The young people expressed a preference for fear-based appeals and a belief that this could work well in HIV-prevention efforts, yet they also stated a desire for more information-based messages about how to protect themselves. Finally, the messages evoking the most emotional responses were those that had been locally conceived rather than ones developed by large-scale donor-funded campaigns. Finding the appropriate balance between fear and efficacy in HIV-prevention messages is imperative. Further research is needed to better understand how and when fear appeals work and do not work in African settings, especially among young people.

Objectives Despite demonstrating only partial efficacy in preventing new infections, available HIV prevention interventions could offer a powerful strategy when combined. In anticipation of combination HIV prevention programs and research studies we estimated the population-level impact of combining effective scalable interventions at high population coverage, determined the factors that influence this impact, and estimated the synergy between the components. Methods We used a mathematical model to investigate the effect on HIV incidence of a combination HIV prevention intervention comprised of high coverage of HIV testing and counselling, risk reduction following HIV diagnosis, male circumcision for HIV-uninfected men, and antiretroviral therapy (ART) for HIV-infected persons. The model was calibrated to data for KwaZulu-Natal, South Africa, where adult HIV prevalence is approximately 23%. Results Compared to current levels of HIV testing, circumcision, and ART, the combined intervention with ART initiation according to current guidelines could reduce HIV incidence by 47%, from 2.3 new infections per 100 person-years (pyar) to 1.2 per 100 pyar within 4 years and by almost 60%, to 1 per 100 pyar, after 25 years. Short-term impact is driven primarily by uptake of testing and reductions in risk behaviour following testing while long-term effects are driven by periodic HIV testing and retention in ART programs. If the combination prevention program incorporated HIV treatment upon diagnosis, incidence could be reduced by 63% after 4 years and by 76% (to about 0.5 per 100 pyar) after 15 years. The full impact of the combination interventions accrues over 10–15 years. Synergy is demonstrated between the intervention components. Conclusion High coverage combination of evidence-based strategies could generate substantial reductions in population HIV incidence in an African generalized HIV epidemic setting. The full impact could be underestimated by the short assessment

Ethical use of antiretroviral resources for HIV prevention in resource poor settings.

PubMed

Rennie, Stuart

2013-08-01

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. © 2013 John Wiley & Sons Ltd.

Adolescent pre-exposure prophylaxis for HIV prevention: current perspectives

PubMed Central

Machado, Daisy Maria; de Sant’Anna Carvalho, Alexandre Machado; Riera, Rachel

2017-01-01

Adolescents are a critical population that is disproportionately impacted by the HIV epidemic. More than 2 million adolescents between the age group of 10 and 19 years are living with HIV, and millions are at risk of infection. HIV risks are considerably higher among girls, especially in high-prevalence settings such as eastern and southern Africa. In addition to girls, there are other vulnerable adolescent subgroups, such as teenagers, who use intravenous (IV) drugs, gay and bisexual boys, transgender youth, male sex workers, and people who fall into more than one of these categories. Pre-exposure prophylaxis (PrEP) is a new intervention for people at high risk for acquiring HIV, with an estimated HIV incidence of >3%. Recent data from trials show evidence of the efficacy of PrEP as a powerful HIV prevention tool in high-risk populations, including men who have sex with men, HIV-1-serodiscordant heterosexual couples, and IV drug users. The reported efficacy in those trials of the daily use of oral tenofovir, alone or in combination with emtricitabine, to prevent HIV infection ranged from 44% to 75% and was heavily dependent on adherence. Despite the proven efficacy of PrEP in adult trials, concerns remain about its feasibility in real-life scenarios due to stigma, cost, and limited clinician experience with PrEP delivery. Recent studies are attempting to expand the inquiry into the efficacy of such HIV prophylaxis approaches in adolescent populations, but there are still many gaps in knowledge, and no country has yet approved it for use with adolescents. The aim of this review was to identify and summarize the evidence from studies on PrEP for adolescents. We have compiled and reviewed published studies focusing on safety, feasibility, adherence to therapeutics, self-perception, and legal issues related to PrEP in people aged between 10 and 24 years.

Reducing HIV Risks in the Places where People Drink: Prevention Interventions in Alcohol Venues

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

Preventing HIV in U.S. women and girls: a call for social action.

PubMed

Gómez, Cynthia A

2011-11-01

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. Copyright © 2011 Jacobs Institute of Women's Health.

Background New York City (NYC) remains an epicenter of the HIV epidemic in the United States. Given the variety of evidence-based HIV prevention strategies available and the significant resources required to implement each of them, comparative studies are needed to identify how to maximize the number of HIV cases prevented most economically. Methods A new model of HIV disease transmission was developed integrating information from a previously validated micro-simulation HIV disease progression model. Specification and parameterization of the model and its inputs, including the intervention portfolio, intervention effects and costs were conducted through a collaborative process between the academic modeling team and the NYC Department of Health and Mental Hygiene. The model projects the impact of different prevention strategies, or portfolios of prevention strategies, on the HIV epidemic in NYC. Results Ten unique interventions were able to provide a prevention benefit at an annual program cost of less than $360,000, the threshold for consideration as a cost-saving intervention (because of offsets by future HIV treatment costs averted). An optimized portfolio of these specific interventions could result in up to a 34% reduction in new HIV infections over the next 20 years. The cost-per-infection averted of the portfolio was estimated to be $106,378; the total cost was in excess of $2 billion (over the 20 year period, or approximately $100 million per year, on average). The cost-savings of prevented infections was estimated at more than $5 billion (or approximately $250 million per year, on average). Conclusions Optimal implementation of a portfolio of evidence-based interventions can have a substantial, favorable impact on the ongoing HIV epidemic in NYC and provide future cost-saving despite significant initial costs.

HIV Treatment and Prevention: A Simple Model to Determine Optimal Investment.

To create a simple model to help public health decision makers determine how to best invest limited resources in HIV treatment scale-up and prevention. A linear model was developed for determining the optimal mix of investment in HIV treatment and prevention, given a fixed budget. The model incorporates estimates of secondary health benefits accruing from HIV treatment and prevention and allows for diseconomies of scale in program costs and subadditive benefits from concurrent program implementation. Data sources were published literature. The target population was individuals infected with HIV or at risk of acquiring it. Illustrative examples of interventions include preexposure prophylaxis (PrEP), community-based education (CBE), and antiretroviral therapy (ART) for men who have sex with men (MSM) in the US. Outcome measures were incremental cost, quality-adjusted life-years gained, and HIV infections averted. Base case analysis indicated that it is optimal to invest in ART before PrEP and to invest in CBE before scaling up ART. Diseconomies of scale reduced the optimal investment level. Subadditivity of benefits did not affect the optimal allocation for relatively low implementation levels. The sensitivity analysis indicated that investment in ART before PrEP was optimal in all scenarios tested. Investment in ART before CBE became optimal when CBE reduced risky behavior by 4% or less. Limitations of the study are that dynamic effects are approximated with a static model. Our model provides a simple yet accurate means of determining optimal investment in HIV prevention and treatment. For MSM in the US, HIV control funds should be prioritized on inexpensive, effective programs like CBE, then on ART scale-up, with only minimal investment in PrEP. © The Author(s) 2015.

Yugoslavia: preventing the spread of HIV and STDs.

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.

Due to heightened vulnerability to HIV from frequent engagement in sex work and overlapping drug-using and sexual networks, women who inject drugs should be a high priority population for pre-exposure prophylaxis (PrEP) and other biomedical HIV prevention tools. Kenya is one of the first African countries to approve oral PrEP for HIV prevention among "key populations," including people who inject drugs and sex workers. The objective of this study was to explore preferences and perceived challenges to PrEP adoption among women who inject drugs in Kisumu, Kenya. We conducted qualitative interviews with nine HIV-uninfected women who inject drugs to assess their perceptions of biomedical HIV interventions, including oral PrEP, microbicide gels, and intravaginal rings. Despite their high risk and multiple biomedical studies in the region, only two women had ever heard of any of these methods. All women were interested in trying at least one biomedical prevention method, primarily to protect themselves from partners who were believed to have multiple other sexual partners. Although women shared concerns about side effects and product efficacy, they did not perceive drug use as a significant deterrent to adopting or adhering to biomedical prevention methods. Beginning immediately and continuing throughout Kenya's planned PrEP rollout, efforts are urgently needed to include the perspectives of high risk women who use drugs in biomedical HIV prevention research and programing.

This paper traces the commonly believed three phases of the HIV/AIDs epidemic in China from the early 1980s to the present time and reviews how the Chinese Government and NGOs are dealing with the crisis. Transmission routes for HIV infection in China are thought to be via IDUs, blood plasma donors, sexual contacts and from mother-to-child transmissions. The author examined interventions for HIV/ AIDS prevention tried in other countries that could provide useful lessons learned and discussed how they could be adapted or replicated in China. While recognising the need for the treatment of HIV positive persons and AIDS patients, this paper is limited to suggesting a number of proven strategic interventions to prevent new HIV infections in China among the "general population", adolescents in schools, sex workers and their clients, injecting drug users, and, prevention of mother to child transmission of HIV/AIDS to stem the epidemic. An extensive literature search of articles in published academic journals, published and unpublished documents of international agencies and development NGOs and media reports was conducted for data source to this paper. Internet search engines such as ProQuest, PubMed, Google and Yahoo search engines were used as well as hard copies of reports and internal documents available at the UNFPA Country Technical Services Team's Office in Bangkok tapped for information.

Condom use remains as the frontline defense against the HIV/AIDS pandemic. Fortunately, an ever-expanding body of empirical literature is currently guiding improvements in use of this prevention strategy. Recent advances include improved measurement of condom use behaviors, advances in condom effectiveness research, innovations in the design of condoms, and greater intervention efficiency for high-risk populations. After reviewing each of these four areas of research, this article will offer speculation about the future of condom use for HIV prevention.

One in three new cases of HIV in South Africa is among adolescents. Given that adolescents are particularly affected, scalable, and cost-effective prevention programs are urgently needed. This study aims to identify opportunities to integrate technology into youth HIV prevention efforts. In 2012, 1107 8th-11th graders completed a paper-and-pencil survey. Respondents were enrolled in one of three public high schools in Langa, a lower income community in Cape Town, South Africa. Eighty-nine percent of respondents have used text messaging (SMS) and 86% have gone online. If an HIV prevention program was offered online, 66% of youth would be somewhat or extremely likely to access it; slightly fewer (55%) felt the same about SMS-based programming. In comparison, 85% said they would be somewhat or extremely likely to access a school-based HIV prevention program. Interest in Internet- (60%) and SMS-based (54%) HIV prevention programming was similar for youth who had a self-appraised risk of HIV compared to youth who appraised their risk to be lower, as it was for youth who were tired of hearing messages about HIV prevention. Technology use is common - even among high school students who live in lower income communities. At the same time, these data reveal that it is not uncommon for youth to be tired of hearing messages about HIV prevention, and many of the typical topics key to HIV prevention have low interest levels among youth. HIV prevention researchers need to be mindful of the extent of existing programming that youth are exposed to. Technology-based programming may be especially amenable to meeting these requirements because of its novelty especially in developing countries, and because interactive functionality can be easily integrated into the program design. Given the preference for school- and Internet-based programming, it seems that a hybrid approach is likely feasible and acceptable.

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
