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

Recent advances in science, program, and policy could better position the nation to achieve its vision of the USA as a place where new HIV infections are rare. Among these developments, passage of the Patient Protection and Affordable Care Act (ACA) in 2010 may prove particularly important, as the health system transformations it has launched offer a supportive foundation for realizing the potential of other advances, both within and beyond the clinical arena. This article summarizes opportunities to expand access to high-impact HIV prevention interventions under the ACA, examines whether available evidence indicates that these opportunities are being realized, and considers potential challenges to further gains for HIV prevention in an era of health reform. This article also highlights the new roles that HIV prevention programs and providers may assume in a health system no longer defined by fragmentation among public health, medical care, and community service providers.
Full Text Available Abstract "No virus, no transmission." Studies have repeatedly shown that viral load (the quantity of virus present in blood and sexual secretions is the strongest predictor of HIV transmission during unprotected sex or transmission from infected mother to child. Effective treatment lowers viral load to undetectable levels. If one could identify and treat all HIV-infected people immediately after infection, the HIV/AIDS epidemic would eventually disappear. Such a radical solution is currently unrealistic. In reality, not all people get tested, especially when they fear stigma and discrimination. Thus, not all HIV-infected individuals are known. Of those HIV-positive individuals for whom the diagnosis is known, not all of them have access to therapy, agree to be treated, or are taking therapy effectively. Some on effective treatment will stop, and in others, the development of resistance will lead to treatment failure. Furthermore, resources are limited: should we provide drugs to asymptomatic HIV-infected individuals without indication for treatment according to guidelines in order to prevent HIV transmission at the risk of diverting funding from sick patients in urgent need? In fact, the preventive potential of anti-HIV drugs is unknown. Modellers have tried to fill the gap, but models differ depending on assumptions that are strongly debated. Further, indications for antiretroviral treatments expand; in places like Vancouver and San Francisco, the majority of HIV-positive individuals are now under treatment, and the incidence of new HIV infections has recently fallen. However, correlation does not necessarily imply causation. Finally, studies in couples where one partner is HIV-infected also appear to show that treatment reduces the risk of transmission. More definite studies, where a number of communities are randomized to either receive the "test-and-treat" approach or continue as before, are now in evaluation by funding agencies. Repeated

The United Nations's (UN) sustainable development goals (SDGs) include the target (3.3) of ending the HIV/AIDS epidemic by 2030. A major challenge in this regard is to curb the incidence of HIV among adolescents, the number two cause of their death in Africa. In Eastern and Southern Africa, they are mainly infected through heterosexual transmission. Research findings about parental influence on the sexual behavior of their adolescent children are reviewed and findings indicate that parental communication, monitoring and connectedness contribute to the avoidance of risky sexual behavior in adolescents. This article evaluates the extent to which these three dimensions of parenting have been factored in to current HIV prevention recommendations relating to adolescent boys and girls. Four pertinent UN reports are analyzed and the results used to demonstrate that the positive role of parents or primary caregivers vis-à-vis risky sexual behavior has tendentially been back-grounded or even potentially undermined. A more explicit inclusion of parents in adolescent HIV prevention policy and practice is essential - obstacles notwithstanding - enabling their indispensable partnership towards ending an epidemic mostly driven by sexual risk behavior. Evidence from successful or promising projects is included to illustrate the practical feasibility and fruitfulness of this approach.

In the absence of an approved and effective vaccine, topical microbicides have become the strategy of choice to provide women with the ability to prevent the sexual transmission of HIV. Topical microbicides are chemical and physical agents specifically developed and formulated for use in either the vaginal or rectal environment to prevent the sexual transmission of infectious organisms. Although a microbicide product will have many of the same properties as other anti-infective therapeutic agents, the microbicide development pathway has significant differences which reflect the complex biological environment in which the products must act. These challenges to the development of an effective microbicide are reflected in the recently released FDA Guidance document which defines the microbicide development algorithm and includes the evaluation of preclinical efficacy and toxicity, and safety and toxicology, and indicates the necessity of testing of the active pharmaceutical product as well as an optimal formulation for delivery of the microbicide product. The microbicide development algorithm requires evaluation of the potential microbicidal agent and final formulated product in assays which mimic the microenvironment of the vagina and rectum during the sexual transmission of HIV, including the evaluation of activity and cytotoxicity in the appropriate biological matrices, toxicity testing against normal vaginal flora and at standard vaginal pH, testing in ectocervical and colorectal explant tissue, and irritation studies to vaginal, rectal and penile tissue. Herein, we discuss currently accepted practices required for the development of a successful microbicide product which will prevent virus transmission in the vaginal and rectal vaults.

The rapidly changing media landscape and proliferation of new technologies creates vast new opportunities for HIV prevention. The fast growth of the relatively new eHealth field is a testament to the excitement and promise of these new technologies. eHealth interventions in HIV prevention tested to date include computer- and Internet-based interventions; chat room interventions; text messaging interventions; and social media. The current article provides a brief review of these types of interventions in HIV prevention, including their unique advantages and evidence of efficacy. Implications for future research in the eHealth HIV prevention field are discussed.

Transgender persons are at high risk for HIV infection, but prevention efforts specifically targeting these people have been minimal. Part of the challenge of HIV prevention for transgender populations is that numerous individual, interpersonal, social, and structural factors contribute to their risk. By combining HIV prevention services with complementary medical, legal, and psychosocial services, transgender persons' HIV risk behaviors, risk determinants, and overall health can be affected simultaneously. For maximum health impact, comprehensive HIV prevention for transgender persons warrants efforts targeted to various impact levels-socioeconomic factors, decision-making contexts, long-lasting protections, clinical interventions, and counseling and education. We present current HIV prevention efforts that reach transgender persons and present others for future consideration.
Expansion of HIV testing and ART treatment are core strategies for achieving the ambitious global goal of ending the HIV epidemic by the end of 2030, and achieving the "90-90-90" target by 2020. In China, great progress in HIV control and prevention has been made; however, there is room to enhance the effectiveness of HIV-related strategies. In addition, some implemented strategies have not achieved their expected output. To confront the challenge of sexual transmission of HIV, which is the main route of transmission in China, more targeted HIV prevention strategies that lead to their expected outcomes are essential. It is important to strengthen existing strategies that have been proved effective. However, it is also critical to create innovative strategies, and there are five approaches to achieve this. First, a holistic perspective should be adopted, to better understand the current situation and problems. This means intervention strategies should give serious consideration of how to meet the sociocultural needs of target populations rather than merely carry out behavioral interventions. Second, community-based HIV prevention settings should have more important roles in providing HIV-related health care services. Moreover, to improve the effectiveness of these strategies, a problem-led working style should be integrated into HIV prevention measures overall. Third, thoroughly analyzing characteristics of the current HIV epidemic using more evidence-based considerations must be undertaken, to better control HIV sexual transmission. Fourth, continued improvement of AIDS prevention and control mechanisms is needed, to ensure their sustainable development. Last, it is necessary to involve more NGOs in HIV prevention work by strengthening their management and working capacities to provide HIV-related services. Also needed is further improvement in both technical and management capacities, so as to build a stable basis for effective response.

Full Text Available Abstract Illicit drug abuse and HIV/AIDS have increased rapidly in the past 10 to 20 years in China. This paper reviews drug abuse in China, the HIV/AIDS epidemic and its association with injection drug use (IDU, and Chinese policies on illicit drug abuse and prevention of HIV/AIDS based on published literature and unpublished official data. As a major drug trans-shipment country with source drugs from the "Golden Triangle" and "Gold Crescent" areas in Asia, China has also become an increasingly important drug consuming market. About half of China's 1.14 million documented drug users inject, and many share needles. IDU has contributed to 42% of cumulatively reported HIV/AIDS cases thus far. Drug trafficking is illegal in China and can lead to the death penalty. The public security departments adopt "zero tolerance" approach to drug use, which conflict with harm reduction policies of the public health departments. Past experience in China suggests that cracking down on drug smuggling and prohibiting drug use alone can not prevent or solve all illicit drug related problems in the era of globalization. In recent years, the central government has outlined a series of pragmatic policies to encourage harm reduction programs; meanwhile, some local governments have not fully mobilized to deal with drug abuse and HIV/AIDS problems seriously. Strengthening government leadership at both central and local levels; scaling up methadone substitution and needle exchange programs; making HIV voluntary counseling and testing available and affordable to both urban and rural drug users; and increasing utilization of outreach and nongovernmental organizations are offered as additional strategies to help cope with China's HIV and drug abuse problem.

Current ideas about HIV prevention include a mixture of primarily biomedical interventions, socio-mechanical interventions such as sterile syringe and condom distribution, and behavioral interventions. This article presents a framework for socially-integrated transdisciplinary HIV prevention that may improve current prevention efforts. It first describes one socially-integrated transdisciplinary intervention project, the Transmission Reduction Intervention Project. We focus on how social aspects of the intervention integrate its component parts across disciplines and processes at different levels of analysis. We then present socially-integrated perspectives about how to improve combination antiretroviral treatment (cART) processes at the population level in order to solve the problems of the treatment cascade and make "treatment as prevention" more effective. Finally, we discuss some remaining problems and issues in such a social transdisciplinary intervention in the hope that other researchers and public health agents will develop additional socially-integrated interventions for HIV and other diseases.

Thirty years after its beginning, the HIV/AIDS epidemic is still raging around the world. According to UNAIDS, in 2011 alone 1.7M deaths were attributable to AIDS, and 2.5M people were newly infected by the virus. Despite the success in treating HIV-infected people with potent antiretroviral drugs, preventing HIV infection is the key to ending the epidemic. Recently, the efficacy of topical and systemic antiviral chemoprophylaxis (i.e., preexposure prophylaxis or "PrEP"), using the same drugs used for HIV treatment, has been demonstrated in a number of clinical trials. However, results from other trials have been inconsistent, especially those evaluating PrEP in women. These inconsistencies may result from our incomplete understanding of pharmacokinetics (PK)/pharmacodynamics (PD) at the mucosal sites of sexual transmission: the male and female gastrointestinal and reproductive tracts. The drug concentrations used in these trials were derived from those used for treatment; however, we still do not know the relationship between the therapeutic and the preventive dose. This article presents the first comprehensive review of the available data in the HIV pharmacology field from animal models to human studies, and outlines gaps, challenges, and future directions. Addressing these pharmacological gaps and challenges will be critical in selecting and advancing future PrEP candidates and strategies with the greatest impact on the HIV epidemic.

No single HIV prevention strategy will be sufficient to control the HIV pandemic. However, a growing number of interventions have shown promise in partially protecting against HIV transmission and acquisition, including knowledge of HIV serostatus, behavioral risk reduction, condoms, male circumcision, needle exchange, treatment of curable sexually transmitted infections, and use of systemic and topical antiretroviral medications by both HIV-infected and uninfected persons. Designing the optimal package of interventions that matches the epidemiologic profile of a target population, delivering that package at the population level, and evaluating safety, acceptability, coverage, and effectiveness, all involve methodological challenges. Nonetheless, there is an unprecedented opportunity to develop "prevention packages" that combine various arrays of evidence-based strategies, tailored to the needs of diverse subgroups and targeted to achieve high coverage for a measurable reduction in population-level HIV transmission. HIV prevention strategies that combine partially effective interventions should be scaled up and evaluated.

The objective of this pilot study was to explore the knowledge of and preferences regarding effective biomedical interventions among high risk individuals attending a sexually transmitted diseases clinic, and to examine the effect of a brief information intervention on preference. Participants completed a baseline assessment, attended a presentation on human immunodeficiency virus (HIV) prevention methods, and completed a postintervention assessment. Outcome measures included: demographics and sexual risk factors, self-perceived HIV risk, and knowledge and attitudes regarding new biomedical methods of HIV prevention. After the baseline evaluation, participants were provided with information on new biomedical prevention strategies. Participants were given the option to review the information by reading a pamphlet or by viewing a brief video containing the same information. Participants (n=97) were female (n=51) and male (n=46). At baseline, only a small minority of participants were aware of the newer biomedical strategies to prevent HIV infection. Postintervention, 40% endorsed having heard about the use of HIV medications to prevent HIV infection; 72% had heard that male circumcision can decrease the risk of acquiring HIV infection in men; and 73% endorsed knowledge of the potential role of microbicides in decreasing the risk of acquiring HIV. Following the intervention, the most preferred prevention method was male condoms, followed by preexposure prophylaxis, and microbicides. The least preferred methods were male circumcision and female condoms. This study provides preliminary information on knowledge and attitudes regarding newer biomedical interventions to protect against HIV infection. PMID:25540597
Full Text Available Binta Sultan,1,2 Paul Benn,1 Laura Waters1 1Department of Genitourinary Medicine, Mortimer Market Centre, Central and North West London NHS Foundation Trust, London, UK; 2Centre for Sexual Health and HIV Research, University College London, London, UK Abstract: The incidence of human immunodeficiency virus (HIV infection continues to rise among core groups and efforts to reduce the numbers of new infections are being redoubled. Post-exposure prophylaxis (PEP is the use of short-term antiretroviral therapy (ART to reduce the risk of acquisition of HIV infection following exposure. Current guidelines recommend a 28-day course of ART within 36–72 hours of exposure to HIV. As long as individuals continue to be exposed to HIV there will be a role for PEP in the foreseeable future. Nonoccupational PEP, the vast majority of which is for sexual exposure (PEPSE, has a significant role to play in HIV prevention efforts. Awareness of PEP and its availability for both clinicians and those who are eligible to receive it are crucial to ensure that PEP is used to its full potential in any HIV prevention strategy. In this review, we provide current evidence for the use of PEPSE, assessment of the risk of HIV transmission, indications for PEP, drug regimens, and management of patients started on PEP. We summarize national and international guidelines for the use of PEPSE. We explore the place of PEP within the wider strategy of reducing HIV incidence rates in the era of treatment as prevention and pre-exposure prophylaxis. We also consider the implications of recent data from interventional and observational studies demonstrating significant reductions in the risk of HIV transmission within a serodiscordant relationship if the HIV-positive partner is taking effective ART upon PEP guidelines.

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

The current analysis considers the HIV prevention research record in the social sciences. We do so with special reference to what has been termed "AIDS Exceptionalism"- departures from standard public health practice and prevention research priorities in favor of alternative approaches to prevention that, it has been argued, emphasize individual rights at the expense of public health protection. In considering this issue, we review the historical context of the HIV epidemic; empirically demonstrate a pattern of prevention research characterized by systematic neglect of prevention interventions for HIV-infected persons; and articulate a rationale for "Prevention for Positives," supportive prevention efforts tailored to the needs of HIV+ individuals. We then propose a social psychological conceptualization of processes that appear to have influenced developments in HIV prevention research and directed its focus to particular target populations. Our concluding section considers whether there are social and research policy lessons to be learned from the record of HIV prevention research that might improve our ability to addresses effectively, equitably, and in timely fashion future epidemics that play out, as HIV does, at the junction of biology and behavior. At the first quarter century of the AIDS epidemic, it is important to weigh our accomplishments against our failures in the fight against AIDS…Future historians will conclude that we cannot escape responsibility for our failure to use effective, scientifically proven strategies to control the AIDS epidemic…They will also likely regard as tragic those instances when we allowed scarce resources to be used to support ideologically driven "prevention" that only served a particular political agenda.Editorial: A Quarter Century of AIDS.

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.

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

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.

Leishmaniasis – human immunodeficiency virus (HIV) coinfection can manifest itself as tegumentary or visceral leishmaniasis. Almost 35 countries have reported autochthonous coinfections. Visceral leishmaniasis is more frequently described. However, usual and unusual manifestations of tegumentary leishmaniasis have been reported mainly in the Americas, but the real prevalence of Leishmania infection in HIV-infected patients is not clear. Regarding the clinical manifestations, there are some reports showing unusual manifestations in visceral leishmaniasis and tegumentary leishmaniasis in HIV-infected patients; yet, the usual manifestations are more frequent. Leishmaniasis diagnosis relies on clinical methods, but serological tests are used to diagnose visceral leishmaniasis despite them having a low sensitivity to tegumentary leishmaniasis. The search for the parasite is used to diagnose both visceral leishmaniasis and tegumentary leishmaniasis. Nevertheless, in HIV-infected patients, the sensitivity of serology is very low. Drugs available to treat leishmaniasis are more restricted and cause severe side effects. Furthermore, in HIV-infected patients, these side effects are more prominent and relapses and lethality are more recurrent. In this article, we discuss the current challenges of tegumentary leishmaniasis and visceral leishmaniasis–HIV infection, focusing mainly on the clinical manifestations, diagnosis, and treatment of leishmaniasis.

Second, the early initiation of ART under TasP will change not only patients' disease courses and treatment experiences--which can affect behaviors that determine clinical treatment success, such as ART adherence and retention--but also quality of life and economic outcomes for HIV-infected individuals. Third, the preventive effects of TasP are likely to alter the composition of the HIV-infected population over time, changing its biological and behavioral characteristics and leading to different costs and outcomes for ART.

Full Text Available ABSTRACTThis 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.

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

Full Text Available 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.

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

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

THE NEED FOR PREVENTION: Women throughout the world face a growing risk of infection with HIV. Consistent condom use, one cornerstone of primary prevention strategy, is not always feasible for many women. Consequently, women urgently need infection prevention technology that is within their personal control. This session will review current efforts to develop and test female-controlled methods for preventing sexual transmission of HIV and other sexually transmitted pathogens. Both physical and chemical methods will be summarized, including recent findings concerning the efficacy and acceptability of the vaginal pouch (female condom), as well as an overview of research on vaginal microbicides. Data from studies of existing over-the-counter spermicides will be reviewed. The wide range of novel microbicidal products currently being evaluated in the laboratory and early clinical trials demonstrate the breadth of possibilities presented by chemical barrier methods. However, formidible challenges face public and private sector research and development efforts. This session will conclude by highlighting several issues related to the clinical evaluation and introduction of female-controlled prevention technology.

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

The first step in preventing mother-to-child HIV transmission (PMTCT) programmes is offering HIV counselling and testing to pregnant women. In developing countries where HIV testing remains rare, it represents a unique opportunity for many women to learn their HIV status. This prenatal HIV testing is not only the entry point to prevention of mother-to-child HIV transmission, but also an occasion for women to sensitize their male partner to sexual risks. Here we explore if these women, HIV-tested as mothers, apply the prevention recommendations they also receive as women. In the Ditrame Plus PMTCT program in Abidjan, Côte d'Ivoire, two cohorts of women (475 HIV-infected women and 400 HIV-negative women) were followed up two years after the pregnancy when they were offered prenatal HIV testing. In each cohort, we compared the proportion of women who communicated with their regular partner on sexual risks, prior to and after prenatal HIV testing. We analysed socio-demographic factors related to this communication. We measured two potential conjugal outcomes of women HIV testing: the level of condom use at sex resumption after delivery and the risk of union break-up. Prenatal HIV testing increased conjugal communication regarding sexual risks, whatever the woman's serostatus. This communication was less frequent for women in a polygamous union or not residing with their partner. Around 30% of women systematically used condoms at sex resumption. Among HIV infected ones, conjugal talk on sexual risks was related to improved condom use. After HIV testing, more HIV-infected women separated from their partners than HIV-uninfected women, despite very few negative reactions from the notified partners. In conclusion, offering prenatal HIV counselling and testing is an efficient tool for sensitizing women and their partners to HIV prevention. But sexual prevention in a conjugal context remains difficult and need to be specifically addressed.

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.

Full Text Available Background: According to the United Nations Joint Program on HIV/AIDS, 33.2 million adults and children are living with the infection worldwide. Of these, two to three million are estimated to be in South Asia. All countries of the region have a low prevalence of human immunodeficiency virus (HIV. However, it is important to review the current epidemiological data to identify the trends of infection as it would have implications on prevention. Materials and Methods: We performed a MEDLINE search using phrases ′South Asia′ plus ′HIV′ , ′AIDS′, and names of individual countries in South Asia (limits: articles published in last 10 years, in English language. Clinical trials, reviews, meta-analyses, letters, editorials, and practice guidelines were all considered. The following countries were included as belonging to South Asia; Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. Recent estimates and data on country status, and details of national control programs were obtained from websites of international agencies such as the World Bank and United Nations Joint Program on HIV/AIDS (UNAIDS. Results and Discussion: This review looks into many aspects of HIV infection in South Asia including country profiles with regard to infection, economic and psychological burden of illness and treatment issues in the South Asian context.

Full Text Available Abstract 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.

Full Text Available Background. Reproductive health programming for female sex workers (FSW may include contraceptive services but rarely addresses safer pregnancy planning. Methods. Adult FSW were enrolled into a cross-sectional study across four sites in Burkina Faso and Togo using respondent-driven sampling. Sociobehavioral questionnaires and HIV counseling and testing were administered. Sample statistics and engagement in HIV treatment were described and compared using Chi-squared statistics. Results. 1,349 reproductive-aged FSW were enrolled from January to July 2013. Overall, 267 FSW (19.8% were currently trying to conceive. FSW trying to conceive were more likely to test positive for HIV at enrollment as compared to women not trying to become pregnant (24.5% versus 17.7%, P<0.01; however awareness of HIV status was similar across groups. Among FSW trying to conceive, 79.0% (211/267 had previously received HIV testing, yet only 33.8% (23/68 of HIV-infected FSW reported a previous HIV diagnosis. Overall 25.0% (17/68 of HIV-infected FSW trying to conceive were on antiretroviral therapy. Conclusion. FSW frequently desire children. However engagement in the HIV prevention and treatment cascade among FSW trying to conceive is poor potentiating periconception transmission risks to partners and infants. Programs to facilitate earlier HIV diagnosis for FSW and safer conception counseling are needed as components of effective combination HIV prevention services.

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

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. Generalized programs and interventions may not have universal, transnational, and crosscultural

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.

Current guidelines on HIV prevention for MSM emphasise the need for 'combination prevention' based on context-specific understandings of HIV risk. MSM in South Africa are a population with a high risk of HIV infection, however there is little research available on the drivers of this risk. In the context of a focus on combination prevention, this paper argues that effective HIV prevention for MSM in South Africa requires an understanding of the factors at multiple 'distances' from individuals that contribute to HIV risk. Based on qualitative research with MSM in Cape Town, South Africa, we situate HIV risk using a socio-ecological framework and identify factors at distal, proximal, and personal, levels that contribute to MSM's high risk of HIV infection. By understanding the interactions and linkages between risk environments and the risk situations in which HIV is transmitted, HIV prevention programmes will be more effectively able to address the multiple drivers of HIV risk in this population.

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.
Full Text Available BACKGROUND: Voluntary contraceptive use by HIV-positive women currently prevents more HIV-positive births, at a lower cost, than anti-retroviral drug (ARV regimens. Despite this evidence, most prevention of mother-to-child transmission (PMTCT programs focus solely on providing ARV prophylaxis to pregnant women and rarely include the prevention of unintended pregnancies among HIV-positive women. METHODOLOGY/PRINCIPAL FINDINGS: To strengthen support for family planning as HIV prevention, we systematically identified key individuals in the field of international HIV/AIDS-those who could potentially influence the issue-and sought to determine their perceptions of barriers to and facilitators for implementing this PMTCT strategy. We used a criteria-based approach to determine which HIV/AIDS stakeholders have the most significant impact on HIV/AIDS research, programs, funding and policy and stratified purposive sampling to conduct interviews with a subset of these individuals. The interview findings pointed to obstacles to strengthening linkages between family planning and HIV/AIDS, including the need for: resources to integrate family planning and HIV services, infrastructure or capacity to provide integrated services at the facility level, national leadership and coordination, and targeted advocacy to key decision-makers. CONCLUSIONS/SIGNIFICANCE: The individuals we identified as having regional or international influence in the field of HIV/AIDS have the ability to leverage an increasingly conducive funding environment and a growing evidence base to address the policy, programmatic and operational challenges to integrating family planning with HIV/AIDS. Fostering greater support for implementing contraception for HIV prevention will require the dedication, collaboration and coordination of many such actors. Our findings can inform a targeted advocacy campaign.

Introduction Currently, Tanzania's HIV prevalence is 5.7%. Gender inequality and Gender Based Violence (GBV) are among factors fuelling the spread of HIV in Tanzania. This study was conducted to assess universal access to HIV prevention services among GBV survivors in Iringa and Dar-es-Salaam where HIV prevalence is as high as 14.7% and 9% respectively compared to a national average of 5.7%. Methods In 2010, a mixed methods study using triangulation model was conducted in Iringa and Dar-es-Sa...

The use of antiretroviral medications in HIV-negative individuals as pre-exposure prophylaxis (PrEP) is a promising approach to prevent HIV infection. Tenofovir disoproxil fumarate (TDF) and emtricitabine exhibit desirable properties for PrEP including: favourable pharmacokinetics that support infrequent dosing; few major drug-drug or drug-food interactions; an excellent clinical safety record; and pre-clinical evidence for efficacy. Several large, randomized, controlled clinical trials are evaluating the safety and efficacy of TDF and emtricitabine for this new indication. A thorough understanding of variability in drug response will help determine future investigations in the field and/or implementation into clinical care. Because tenofovir and emtricitabine are nucleos(t)ide analogues, the HIV prevention and toxicity effects depend on the triphosphate analogue formed intracellularly. This review identifies important cellular pharmacology considerations for tenofovir and emtricitabine, which include drug penetration into relevant tissues and cell types, race/ethnicity/pharmacogenetics, gender, cellular activation state and appropriate episodic or alternative dosing strategies based on pharmacokinetic principles. The current state of knowledge in these areas is summarized and the future utility of intracellular pharmacokinetics/pharmacodynamics for the PrEP field is discussed. PMID:21118913
Full Text Available HIV/AIDS is a leading cause of mortality and morbidity worldwide. In spite of successful interventions and treatment protocols, an HIV vaccine would be the ultimate prevention and control strategy. Ever since identification of HIV/AIDS, there have been meticulous efforts for vaccine development. The specific aim of this paper is to review recent vaccine efficacy trials and associated advancements and discuss the current challenges and future directions. Recombinant DNA technologies greatly facilitated development of many viral products which were later incorporated into vectors for effective vaccines. Over the years, a number of scientific approaches have gained popularity and include the induction of neutralizing antibodies in late 1980s, induction of CD8 T cell in early 1990s, and combination approaches currently. Scientists have hypothesized that stimulation of right sequences of somatic hypermutations could induce broadly reactive neutralizing antibodies (bnAbs capable of effective neutralization and viral elimination. Studies have shown that a number of host and viral factors affect these processes. Similarly, eliciting specific CD8 T cells immune responses through DNA vaccines hold future promises. In summary, future studies should focus on the continuous fight between host immune responses and ever-evasive viral factors for effective vaccines.

Full Text Available Introduction: There are limited data characterizing the burden of HIV among men who have sex with men (MSM in Malawi. Epidemiologic research and access to HIV prevention, treatment and care services have been traditionally limited in Malawi by criminalization and stigmatization of same-sex practices. To inform the development of a comprehensive HIV prevention intervention for Malawian MSM, we conducted a community-led assessment of HIV prevalence and correlates of infection. Methods: From April 2011 to March 2012, 338 MSM were enrolled in a cross-sectional study in Blantyre, Malawi. Participants were recruited by respondent-driven sampling methods (RDS, reaching 19 waves. Trained staff administered the socio-behavioural survey and HIV and syphilis voluntary counselling and testing. Results: Crude HIV and syphilis prevalence estimates were 15.4% (RDS-weighted 12.5%, 95% confidence interval (CI: 7.3–17.8 and 5.3% (RDS-weighted 4.4%, 95% CI: 3.1–7.6, respectively. Ninety per cent (90.4%, unweighted of HIV infections were reported as being previously undiagnosed. Participants were predominantly gay-identified (60.8% or bisexually identified (36.3%; 50.7% reported recent concurrent relationships. Approximately half reported consistent condom use (always or almost always with casual male partners, and proportions were relatively uniform across partner types and genders. The prevalence of perceived and experienced stigma exceeded 20% for almost all variables, 11.4% ever experienced physical violence and 7% were ever raped. Current age >25 years (RDS-weighted adjusted odds ratio (AOR 3.9, 95% CI: 1.2–12.7, single marital status (RDS-weighted AOR: 0.3; 95% CI: 0.1–0.8 and age of first sex with a man <16 years (RDS-weighted AOR: 4.3, 95% CI: 1.2–15.0 were independently associated with HIV infection. Conclusions: Results demonstrate that MSM represent an underserved, at-risk population for HIV services in Malawi and merit comprehensive HIV
Full Text Available 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.

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

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.

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.

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/AIDS is one of the most serious public health challenges globally. Despite the great efforts that are being devoted to prevent, treat and to better understand the disease, it is one of the main causes of morbidity and mortality worldwide. Currently, there are 30 drugs or combinations of drugs approved by FDA. Because of the side-effects, price and drug resistance, it is essential to discover new targets, to develop new technology and to find new anti-HIV drugs. This review summarizes the major targets and assays currently used in anti-HIV drug screening.

Full Text Available 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.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.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.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.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 South Africa. While some adaptation of

Full Text Available BACKGROUND: Most HIV-1 transmission in Africa occurs among HIV-1-discordant couples (one partner HIV-1 infected and one uninfected who are unaware of their discordant HIV-1 serostatus. Given the high HIV-1 incidence among HIV-1 discordant couples and to assess efficacy of interventions for reducing HIV-1 transmission, HIV-1 discordant couples represent a critical target population for HIV-1 prevention interventions and prevention trials. Substantial regional differences exist in HIV-1 prevalence in Africa, but regional differences in HIV-1 discordance among African couples, has not previously been reported. METHODOLOGY/PRINCIPAL FINDINGS: The Partners in Prevention HSV-2/HIV-1 Transmission Trial ("Partners HSV-2 Study", the first large HIV-1 prevention trial in Africa involving HIV-1 discordant couples, completed enrollment in May 2007. Partners HSV-2 Study recruitment data from 12 sites from East and Southern Africa were used to assess HIV-1 discordance among couples accessing couples HIV-1 counseling and testing, and to correlate with enrollment of HIV-1 discordant couples. HIV-1 discordance at Partners HSV-2 Study sites ranged from 8-31% of couples tested from the community. Across all study sites and, among all couples with one HIV-1 infected partner, almost half (49% of couples were HIV-1 discordant. Site-specific monthly enrollment of HIV-1 discordant couples into the clinical trial was not directly associated with prevalence of HIV-1 discordance, but was modestly correlated with national HIV-1 counseling and testing rates and access to palliative care/basic health care (r = 0.74, p = 0.09. CONCLUSIONS/SIGNIFICANCE: HIV-1 discordant couples are a critical target for HIV-1 prevention in Africa. In addition to community prevalence of HIV-1 discordance, national infrastructure for HIV-1 testing and healthcare delivery and effective community outreach strategies impact recruitment of HIV-1 discordant couples into HIV-1 prevention trials.

This study examines the relationship between masculine ideology, adherence to norms, and HIV prevention among young Black heterosexual and gay men on the campus of a historically Black college/university. The data from four focus groups and nine individual interviews (N = 35) were aggregated and two recurring themes emerged: sexual communication, and mate availability. Additional themes related to HIV prevention were stigma, protection, and testing. The importance of investigating masculinity with young men is highlighted and implications for professionals working with college students to prevent the transmission of HIV are included.

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.

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

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.
Full Text Available Abstract This review summarizes recent advances and current gaps in understanding of innate immunity to human immunodeficiency virus (HIV infection, and identifies key scientific priorities to enable application of this knowledge to the development of novel prevention strategies (vaccines and microbicides. It builds on productive discussion and new data arising out of a workshop on innate immunity against HIV held at the European Commission in Brussels, together with recent observations from the literature. Increasing evidence suggests that innate responses are key determinants of the outcome of HIV infection, influencing critical events in the earliest stages of infection including the efficiency of mucosal HIV transmission, establishment of initial foci of infection and local virus replication/spread as well as virus dissemination, the ensuing acute burst of viral replication, and the persisting viral load established. They also impact on the subsequent level of ongoing viral replication and rate of disease progression. Modulation of innate immunity thus has the potential to constitute a powerful effector strategy to complement traditional approaches to HIV prophylaxis and therapy. Importantly, there is increasing evidence to suggest that many arms of the innate response play both protective and pathogenic roles in HIV infection. Consequently, understanding the contributions made by components of the host innate response to HIV acquisition/spread versus control is a critical pre-requisite for the employment of innate immunity in vaccine or microbicide design, so that appropriate responses can be targeted for up- or down-modulation. There is also an important need to understand the mechanisms via which innate responses are triggered and mediate their activity, and to define the structure-function relationships of individual innate factors, so that they can be selectively exploited or inhibited. Finally, strategies for achieving modulation of

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.

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

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. 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. 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. 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.

A combination of advances spanning from isolation to delivery of potent HIV-specific antibodies has begun to revolutionize understandings of antibody-mediated antiviral activity. As a result, the set of broadly neutralizing and highly protective antibodies has grown in number, diversity, potency, and breadth of viral recognition and neutralization. These antibodies are now being further enhanced by rational engineering of their anti-HIV activities and coupled to cutting edge gene delivery and strategies to optimize their pharmacokinetics and biodistribution. As a result, the prospects for clinical use of HIV-specific antibodies to treat, clear, and prevent HIV infection are gaining momentum. Here we discuss the diverse methods whereby antibodies are being optimized for neutralization potency and breadth, biodistribution, pharmacokinetics, and effector function with the aim of revolutionizing HIV treatment and prevention options.

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.

This podcast is based on the November 24, 2015 CDC Vital Signs report. Preexposure prophylaxis, or PrEP, is a daily medicine that can be used to prevent getting HIV. PrEP is for people who donât have HIV but who are at very high risk for getting it from sex or injection drug use. Unfortunately, many people who can benefit from PrEP arenât taking it.

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

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

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, fift...
Full Text Available Sonja G Schütz, Jessica Robinson-Papp Department of Neurology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Distal symmetric polyneuropathy (DSP related to human immunodeficiency virus (HIV is one of the most common neurologic complications of HIV, possibly affecting as many as 50% of all individuals infected with HIV. Two potentially neurotoxic mechanisms have been proposed to play a crucial role in the pathogenesis of HIV DSP: neurotoxicity resulting from the virus and its products; as well as adverse neurotoxic effects of medications used in the treatment of HIV. Clinically, HIV DSP is characterized by a combination of signs and symptoms that include decreased deep tendon reflexes at the ankles and decreased sensation in the distal extremities as well as paresthesias, dysesthesias, and pain in a symmetric stocking–glove distribution. These symptoms are generally static or slowly progressive over time, and depending on the severity, may interfere significantly with the patient's daily activities. In addition to the clinical picture, nerve conduction studies and skin biopsies are often pursued to support the diagnosis of HIV DSP. Anticonvulsants, antidepressants, topical agents, and nonspecific analgesics may help relieve neuropathic pain. Specifically, gabapentin, lamotrigine, pregabalin, amitriptyline, duloxetine, and high-dose topical capsaicin patches have been used in research and clinical practice. Further research is needed to elucidate the pathogenesis of HIV DSP, thus facilitating the development of novel treatment strategies. This review discusses the epidemiology, pathophysiology, clinical findings, diagnosis, and management of DSP in the setting of HIV. Keywords: neuropathy, human immunodeficiency virus, acquired immunodeficiency syndrome, AIDS, distal symmetric polyneuropathy, DSP, pain

Full Text Available Abstract Background In the absence of reliable data, antenatal HIV surveillance has been used to monitor the HIV epidemic since the late 1980s. Currently, routine data from Prevention of Mother-to-child HIV transmission (PMTCT programmes are increasingly available. Evaluating whether the PMTCT programme reports provide comparable HIV prevalence estimates with the antenatal surveillance reports is important. In this study, we compared HIV prevalence estimates from routine PMTCT programme and antenatal surveillance in Addis Ababa with the aim to come up with evidence based recommendation. Methods Summary data were collected from PMTCT programmes and antenatal surveillance reports within the catchment of Addis Ababa. The PMTCT programme data were obtained from routine monthly reports from 2004 to 2009 and from published antenatal HIV surveillance reports from 2003 to 2009. Data were analysed using descriptive statistics. Results In Addis Ababa, PMTCT sites had increased from six in 2004 to 54 in 2009. The site expansion was accompanied by an increased number of women testing. There were marked increases in the rate of HIV testing following the introduction of routine opt-out HIV testing approach. Paralleling these increases, the HIV prevalence showed a steady decline from 10.0% in 2004 to 4.5% in 2009. There were five antenatal surveillance sites from 2003 to 2007 in Addis Ababa and they increased to seven by 2009. Four rounds of surveillance data from five sites showed a declining trend in HIV prevalence over the years. The overall antenatal surveillance data also showed that the HIV prevalence among antenatal attendees had declined from 12.4% in 2003 to 5.5% in 2009. The HIV prevalence estimates from PMTCT programme were 6.2% and 4.5% and from antenatal surveillance 6.1 and 5.5% in 2008 and 2009 respectively. Conclusions There were consistent HIV prevalence estimates from PMTCT programme and from antenatal surveillance reports. Both data sources

Despite the recognized need for structural HIV prevention interventions, few scientific programs have integrated women's property and inheritance rights with HIV prevention and treatment. The current study focused on a community-led land and property rights intervention that was implemented in two rural areas of Western Kenya with high HIV prevalence rates (24-30%). The program was designed to respond to women's property rights violations in order to reduce HIV risk at the local level. Through in-depth interviews with twenty program leaders, we identified several facilitators to program implementation, including the leadership of home-based HIV caregivers and involvement of traditional leaders in mediating property rights disputes. We also identified the voluntary basis of the intervention and its lack of integration with the formal justice system as implementation barriers. Our findings can guide future research and design of structural HIV prevention strategies that integrate women's economic empowerment through property and inheritance rights.

The oral manifestations of human immunodeficiency virus infection have changed drastically since the introduction of the highly active anti-retroviral therapy (HAART) in developed countries. Recent studies have documented significant reductions in morbidity and mortality rates among HIV-infected patients on HAART. This article focuses on the latest information about the oral manifestations of HIV infection and will discuss the impact of HAART.

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

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

Media messages can facilitate the delivery of accurate information related to HIV and sexually transmitted infection. This study's purpose was to examine preexisting media campaigns from the iMPPACS study to assess age-, gender-, and culturally appropriate components identified by African American females who attend historically Black colleges/universities. In 3 separate focus group sessions, 31 Black female college students (M age = 20) viewed 4 vignettes and heard 3 audio-only clips, then ranked and commented on them based on perceived satisfaction with HIV prevention content and appropriateness of delivery. Conventional qualitative analysis using NVivo software was performed until saturation of content was achieved and themes derived. Six major themes emerged and were designated as (a) social media; (b) mirror image; (c) visually dynamic advertisements; (d) the real world; (e) people, place, things; and (f) HIV knowledge. Visually stimulating content (i.e., graphics) was found to be most appealing in marketing HIV prevention, with brief monologue/dialogue from scenarios that resemble daily life. Socially and culturally relevant HIV prevention messages are important to Black college female students. Participants recommended creating short audiovisual messages that encompass familiar contexts like dorm rooms and appealing graphics for HIV health promotion messages, such as emojis. Future audio-only prevention advertisements for this population should use recognizable voices (e.g., celebrities). Finally, messaging should be promoted on open and closed circuit social media platforms.
Full Text Available The efficiency of transmission of HIV depends on the infectiousness of the index case and the susceptibility of those exposed. Infectiousness is dictated by the concentration of HIV-1 in relevant fluids (regardless of route of transmission and the viral genotype and phenotype. People newly infected with HIV-1 (i.e. acute infection and those with STI co-infections excrete such a large concentration of virus as to be “hyperinfectious.” The actual transmission of HIV likely occurs in the first few hours after exposure. The probability of transmission may be as low as 1/10,000 episodes of intercourse or 1/10 sexual exposures when anal intercourse is practiced. The transmission of HIV is generally limited to one or a small number of founder variants which themselves may be “hyperinfectious.” Synergistic behavioural and biologic HIV prevention strategies have been developed and implemented. Safer sex includes limiting the number of sexual partners, use of male latex condoms, and structural interventions to reduce exposure. These strategies appear to have contributed to reduced HIV incidence in many countries. Biological interventions have proved catalytic: these include treatment of inflammatory cofactors, voluntary male circumcision and use of antiviral agents either for infected people (who can be rendered remarkably less contagious or as pre- and post-exposure prophylaxis (PrEP and PEP. Ecologic evidence suggests that broader, earlier antiviral treatment of HIV may be reducing incidence in some (but not all populations. However, maximal benefit of HIV “treatment for prevention” and application of PrEP will likely require a program of universal “test and treat,” where many more infected patients are identified, linked to care, and treated very early in disease and for life. Community randomized trials designed to support this approach are under way in Africa. The “test and treat” prevention strategy is resource-intensive and

Full Text Available One of the major characteristics of HIV-1 is its high genetic variability and extensive heterogeneity. This characteristic is due to its molecular traits, which in turn allows it to vary, recombine, and diversify at a high frequency. As such, it generates complex molecular forms, termed recombinants, which evade the human immune system and so survive. There is no sequence constraint to the recombination pattern as it appears to occur at inter-group (between groups M and O, as well as inter- and intra-subtype within group M. Rapid emergence and active global transmission of HIV-1 recombinants, known as circulating recombinant forms (CRFs and unique recombinant forms (URFs, requires urgent attention. To date, 55 CRFs have been reported around the world. The first CRF01_AE originated from Central Africa but spread widely in Asia. The most recent CRF; CRF55_01B is a recombinant form of CRF01_AE and subtype B, although its origin is yet to be publicly disclosed. HIV-1 recombination is an ongoing event and plays an indispensable role in HIV epidemics in different regions. Africa, Asia and South America are identified as recombination hot-spots. They are affected by continual emergence and co-circulation of newly emerging CRFs and URFs, which are now responsible for almost 20% of HIV-1 infections worldwide. Better understanding of recombinants is necessary to determine their biological and molecular attributes.

Understanding the epidemiologic definition of epidemic versus non-epidemic spread of an infectious disease agent and the different patterns of heterosexual HIV transmission are needed to fully understand the low potential for heterosexual HIV epidemics in most heterosexual populations. Epidemic sexual HIV transmission can occur only in populations where there are large numbers of persons who have unprotected sex with multiple and concurrent sex partners. How high HIV prevalence may reach in these populations depends on the size and overlap of sex networks, and the prevalence of facilitating and protective factors that can greatly increase or limit the amount of infected blood and sexual fluids exchanged during intercourse. The wide difference in potentials for heterosexual HIV epidemics that exists within and between countries must be recognized, accepted and monitored in order to design and focus prevention strategies where they are most needed and most effective.

The Human Immunodeficiency Virus (HIV) epidemic has evolved, with an increasing non-communicable disease (NCD) burden emerging and need for long-term management, yet there are limited data to help delineate the optimal care model to screen for NCDs for this patient population. The primary aim was to compare rates of NCD preventive screening in persons living with HIV/AIDS (PLWHA) by type of HIV care model, focusing on metabolic/cardiovascular disease (CVD) and cancer screening. We hypothesized that primary care models that included generalists would have higher preventive screening rates. Prospective observational cohort study. Partners HealthCare System (PHS) encompassing Brigham & Women's Hospital, Massachusetts General Hospital, and affiliated community health centers. PLWHA age >18 engaged in active primary care at PHS. HIV care model categorized as infectious disease (ID) providers only, generalist providers only, or ID plus generalist providers. Odds of screening for metabolic/CVD outcomes including hypertension (HTN), obesity, hyperlipidemia (HL), and diabetes (DM) and cancer including colorectal cancer (CRC), cervical cancer, and breast cancer. In a cohort of 1565 PLWHA, distribution by HIV care model was 875 ID (56%), 90 generalists (6%), and 600 ID plus generalists (38%). Patients in the generalist group had lower odds of viral suppression but similar CD4 counts and ART exposure as compared with ID and ID plus generalist groups. In analyses adjusting for sociodemographic and clinical covariates and clustering within provider, there were no significant differences in metabolic/CVD or cancer screening rates among the three HIV care models. There were no notable differences in metabolic/CVD or cancer screening rates by HIV care model after adjusting for sociodemographic and clinical factors. These findings suggest that HIV patients receive similar preventive health care for NCDs independent of HIV care model.
Full Text Available Abstract Background A large proportion of the 2.5 million new adult HIV infections that occurred worldwide in 2007 were in stable couples. Feasible and acceptable strategies to improve HIV prevention in a conjugal context are scarce. In the preparatory phase of the ANRS 12127 Prenahtest multi-site HIV prevention trial, we assessed the acceptability of couple-oriented post-test HIV counseling (COC and men's involvement within prenatal care services, among pregnant women, male partners and health care workers in Cameroon, Dominican Republic, Georgia and India. Methods Quantitative and qualitative research methods were used: direct observations of health services; in-depth interviews with women, men and health care workers; monitoring of the COC intervention and exit interviews with COC participants. Results In-depth interviews conducted with 92 key informants across the four sites indicated that men rarely participated in antenatal care (ANC services, mainly because these are traditionally and programmatically a woman's domain. However men's involvement was reported to be acceptable and needed in order to improve ANC and HIV prevention services. COC was considered by the respondents to be a feasible and acceptable strategy to actively encourage men to participate in prenatal HIV counseling and testing and overall in reproductive health services. Conclusions One of the keys to men's involvement within prenatal HIV counseling and testing is the better understanding of couple relationships, attitudes and communication patterns between men and women, in terms of HIV and sexual and reproductive health; this conjugal context should be taken into account in the provision of quality prenatal HIV counseling, which aims at integrated PMTCT and primary prevention of HIV.
Full Text Available This article explores the ways in which (a Indigenous youth involved in an HIV intervention took up and reclaimed their cultures as a project of defining ‘self’, and (b how Indigenous ‘culture’ can be used as a tool for resistance, HIV prevention and health promotion. Data were drawn from the Taking Action Project: Using arts-based approaches to develop Aboriginal youth leadership in HIV prevention. ‘By youth, for youth’ HIV education and awareness workshops were facilitated in six Indigenous communities across Canada, incorporating traditional and contemporary art forms to explore how youth perceived the links between structural inequality and HIV vulnerability. Over 100 youth participated, with 70 partaking in individual interviews to reflect on their experiences at the workshops. Interviews were audio-recorded, transcribed verbatim and analysed using NVivo software. Indigenous youth understood culture as a complex construct that included reconnecting to land, body, history, community and ceremony. For many youth, being Aboriginal and participating in cultural activities was seen as important for intergenerational healing, empowerment, health and combatting HIV. Youth spoke excitedly of their attempts to reclaim their languages and cultures despite barriers. They also understood art as a medium for self-expression and as an important site of cultural evolution. Our project demonstrates that the incorporation of culture within health strategies is important for effective HIV prevention amongst Indigenous youth. Reclaiming Indigenous cultures, languages and ceremonies may help to nurture future generations, diminish cycles of victimisation and combat hopelessness by reconnecting youth to stories of resistance and survival.

The external environment of an organisation influences the desired goals and interventions of that organisation in many ways. However, strategies for influencing the external context to create a more enabling environment for the interventions of non-governmental organisations (NGOs) are often inadequately addressed. This article draws on an empirical multiple-case study conducted in 2007/08 of four NGOs providing HIV-prevention services to young people in several low-resource, high-HIV-prevalence communities in Cape Town, South Africa. In an earlier study, young people reported that the external environment hampered their ability to institutionalise HIV-prevention messages. The current study explored how the NGOs endeavoured to influence the external environment, and the challenges they faced. The findings show that the NGOs practised a combination of strategies, encompassing inter-organisational relationships, influencing policy, and championing by example. Key constraints to their influencing practices included fear of losing legitimacy as a service provider; inadequate knowledge, skills and opportunity; perceived deviation from their usual work; inadequate funding; conflicts over values and messages; and a habit of focusing more on young people's individual behaviours and less on context. The development management task of influencing the external environment to create an environment more conducive to HIV prevention seemed constrained mainly because: 1) donors focused on funding and monitoring the activities they were interested in and conceptualised as HIV-prevention services; 2) NGO efforts were restricted to programme implementation based on agreed deliverables, thus influencing was mainly confined to championing by example; consequently, 3) 'influencing efforts' to create an environment more conducive to HIV prevention were left mainly to young people themselves, who can affect their peers only to a narrow, albeit crucial extent. The external environment
Full Text Available Abstract 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.

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.
Full Text Available Vaginal HIV transmission accounts for the majority of new infections worldwide. Currently, multiple efforts to prevent HIV transmission are based on pre-exposure prophylaxis with various antiretroviral drugs. Here, we describe two novel nanoformulations of the reverse transcriptase inhibitor rilpivirine for pericoital and coitus-independent HIV prevention. Topically applied rilpivirine, encapsulated in PLGA nanoparticles, was delivered in a thermosensitive gel, which becomes solid at body temperature. PLGA nanoparticles with encapsulated rilpivirine coated the reproductive tract and offered significant protection to BLT humanized mice from a vaginal high-dose HIV-1 challenge. A different nanosuspension of crystalline rilpivirine (RPV LA, administered intramuscularly, protected BLT mice from a single vaginal high-dose HIV-1 challenge one week after drug administration. Using transmitted/founder viruses, which were previously shown to establish de novo infection in humans, we demonstrated that RPV LA offers significant protection from two consecutive high-dose HIV-1 challenges one and four weeks after drug administration. In this experiment, we also showed that, in certain cases, even in the presence of drug, HIV infection could occur without overt or detectable systemic replication until levels of drug were reduced. We also showed that infection in the presence of drug can result in acquisition of multiple viruses after subsequent exposures. These observations have important implications for the implementation of long-acting antiretroviral formulations for HIV prevention. They provide first evidence that occult infections can occur, despite the presence of sustained levels of antiretroviral drugs. Together, our results demonstrate that topically- or systemically administered rilpivirine offers significant coitus-dependent or coitus-independent protection from HIV infection.
Full Text Available Many attempts have been made or are ongoing for HIV prevention and HIV cure. Many successes are in the list, particularly for HIV drugs, recently proposed also for prevention. However, no eradication of infection has been achieved so far with any drug.Further, a residual immune dysregulation associated to chronic immune activation and incomplete restoration of B and T cell subsets, together with HIV DNA persistence in reservoirs, are still unmet needs of the highly active antiretroviral therapy (HAART, causing novel non-AIDS related diseases that account for a higher risk of death even in virologically suppressed patients. These ART unmet needs represent a problem, which is expected to increase by ART roll out. Further, in countries such as South Africa, where 6 millions of individuals are infected, ART appears unable to contain the epidemics. Regretfully, all the attempts at developing a preventative vaccine have been largely disappointing. However, recent therapeutic immunization strategies have opened new avenues for HIV treatment, which might be exploitable also for preventative vaccine approaches. For example, immunization strategies aimed at targeting key viral products responsible of virus transmission, activation and maintenance of virus reservoirs may intensify drug efficacy and lead to a functional cure providing new perspectives also for prevention and future virus eradication strategies. However, this approach imposes new challenges to the scientific community, vaccine developers and regulatory bodies, such as the identification of novel immunological and virological biomarkers to assess efficacy endpoints, taking advantage from the natural history of infection and exploiting lessons from former trials.This review will focus first on recent advancement of therapeutic strategies, then on the progresses made in preventative approaches, discussing concepts and problems for the way ahead for the development of vaccines for HIV treatment

As patients with HIV age, they are at risk of developing non-AIDS defining malignancies. We performed a questionnaire study to evaluate colorectal and breast cancer screening among HIV-positive and HIV-negative patients seeking care from either an integrated (HIV/primary care), nonintegrated (specialized HIV), or general internal medicine clinic between August 2010 and July 2011. We performed a logistic regression to determine the odds of cancer screening. A total of 813 surveys were collected, and 762 were included in the analysis. As much as 401 were from HIV-positive patients. Patients with HIV were less likely to be current with their colorectal cancer screening (CRCS) (54.4% versus 65.0%, p=0.009); mammography rates were 24.3% versus 62.3% if done during the past year (pscreening in HIV-positive patients compared to negative controls was not statistically significant (OR 0.8; 95% CI 0.5-1.3); however, HIV-positive women remained significantly less likely to be current with breast cancer screening (BCS) whether their mammogram was completed within 1 year (OR 0.1, 95% CI 0.1-0.2) or within 5 years (OR 0.1, 95% CI 0.0-0.2). Integrated care was not associated with improved screening; however, having frequent visits to a primary care physician (PCP) increased the likelihood of getting screened. BCS was lower in HIV-positive compared to HIV-negative women. Frequent visits to a PCPs improved cancer screening.
In the scientific literature on fertility and assisted reproduction, and in the corresponding area of clinical practice, increasing attention has been paid to two groups: people living with the human immunodeficiency virus (HIV) and gay men. However, research on fertility in the context of HIV focuses almost exclusively on heterosexual couples, whereas studies on non-heterosexual reproduction rarely mention HIV, despite the fact that, in many western countries, HIV prevalence among men who have sex with men is higher than ever before and men who have sex with men are the only group in which new HIV infections are on the rise. This review identifies links between reproduction, HIV and homosexuality, showing that, historically, they are closely intertwined, which has important implications for current issues facing HIV care and fertility services. Considering sex and parenthood as two different but related kinds of intimacy and kinship, the dual role semen plays in sexually transmitted infection and in assisted reproduction is discussed. The review reflects on the future of sperm donation and HIV prevention, asking whether two challenges that potentially face healthcare and medicine today - the shortage of 'high-quality' sperm and the 'surplus' of infected semen - could be addressed by a greater exchange of knowledge.

Homeless persons suffer disproportionately high rates of HIV infection, and moving into permanent supportive housing (PSH) can provide a stable base from which to access needed prevention services. However, little is known about HIV risk or prevention behavior during this critical time of transition. The current study investigated STI and HIV risk and prevention behavior and recent use of prevention and treatment services (i.e., education, testing, medication) among homeless persons preparing to move into PSH. Data come from interviews with 421 homeless adults before they moved into PSH. Thirty-seven percent of the respondents were sexually active; of those, 75.7% reported unprotected sex. Nearly two-thirds (64%) reported past year HIV testing and 40% reported testing for another STI. Fewer than one-third (31%) of respondents reported receiving posttest counseling at their last HIV test. HIV seropositivity was self-reported by 10%. Among those persons who were HIV-positive, 57.1% reported less than 100% antiretroviral (ARV) adherence. Among HIV-negative respondents, less than 1% had been prescribed preexposure prophylaxis (PrEP). Less than half (46.4%) of the sample reported any HIV prevention education in the past year. This population of homeless adults about to move into PSH report high rates of HIV risk behavior, but low rates of HIV prevention education and very little PrEP utilization. Further, low rates of ARV adherence among HIV-positive respondents indicate significant risk for HIV transmission and acquisition. Entering PSH is a period of transition for homeless persons when integrated care is critically important to ensure positive health outcomes, but these data suggest that PrEP and other HIV prevention services are poorly accessed among this population. As such, multipronged services that integrate PrEP and other HIV prevention services are needed to prevent transmission and acquisition of HIV in this high-risk, vulnerable population and ensure the

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

Objective To conduct a critical review of all HIV prevention intervention studies conducted with adolescents in juvenile justice settings to inform future intervention development. Method PubMed and PsycInfo database searches were conducted for peer-reviewed, published HIV prevention intervention studies with juvenile offenders. Results Sixteen studies were identified (N = 3,700 adolescents). Half of the projects utilized rigorous methodologies to determine intervention effect on behavior change, such as conducting a randomized controlled trial (n = 8). Nine studies reported behaviors at least 3 months post-intervention and five out of nine showed decreases in sexual risk behavior. Conclusions Several HIV prevention programs with juvenile offenders have led to sexual risk reduction, although effect sizes are modest. Most existing programs have neglected to address the impact of family, mental health, and substance use on HIV risk. More work is needed to develop evidence-based interventions that include HIV prevention strategies relevant and appropriate for the juvenile justice setting. PMID:19741021
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 healt...
Full Text Available BACKGROUND: WHO-guidelines for prevention of mother-to-child transmission of HIV-1 in resource-limited settings recommend complex maternal antiretroviral prophylaxis comprising antenatal zidovudine (AZT, nevirapine single-dose (NVP-SD at labor onset and AZT/lamivudine (3TC during labor and one week postpartum. Data on resistance development selected by this regimen is not available. We therefore analyzed the emergence of minor drug-resistant HIV-1 variants in Tanzanian women following complex prophylaxis. METHOD: 1395 pregnant women were tested for HIV-1 at Kyela District Hospital, Tanzania. 87/202 HIV-positive women started complex prophylaxis. Blood samples were collected before start of prophylaxis, at birth and 1-2, 4-6 and 12-16 weeks postpartum. Allele-specific real-time PCR assays specific for HIV-1 subtypes A, C and D were developed and applied on samples of mothers and their vertically infected infants to quantify key resistance mutations of AZT (K70R/T215Y/T215F, NVP (K103N/Y181C and 3TC (M184V at detection limits of <1%. RESULTS: 50/87 HIV-infected women having started complex prophylaxis were eligible for the study. All women took AZT with a median duration of 53 days (IQR 39-64; all women ingested NVP-SD, 86% took 3TC. HIV-1 resistance mutations were detected in 20/50 (40% women, of which 70% displayed minority species. Variants with AZT-resistance mutations were found in 11/50 (22%, NVP-resistant variants in 9/50 (18% and 3TC-resistant variants in 4/50 women (8%. Three women harbored resistant HIV-1 against more than one drug. 49/50 infants, including the seven vertically HIV-infected were breastfed, 3/7 infants exhibited drug-resistant virus. CONCLUSION: Complex prophylaxis resulted in lower levels of NVP-selected resistance as compared to NVP-SD, but AZT-resistant HIV-1 emerged in a substantial proportion of women. Starting AZT in pregnancy week 14 instead of 28 as recommended by the current WHO-guidelines may further increase

Full Text Available This review provides an overview of the current status of the global HIV pandemic and strategies to bring it under control. It updates numerous preventive approaches including behavioral interventions, male circumcision, pre- and post-exposure prophylaxis, vaccines, and microbicides. The manuscript summarizes current anti-retroviral treatment options, their impact in the western world, and difficulties faced by emerging and resource-limited nations in providing and maintaining appropriate treatment regimens. Current clinical and pre-clinical approaches towards a cure for HIV are described, including new drug compounds that target viral reservoirs and gene therapy approaches aimed at altering susceptibility to HIV infection. Recent progress in vaccine development is summarized, including novel approaches and new discoveries.
Full Text Available The rigorous evaluation of the impact of combination HIV prevention packages at the population level will be critical for the future of HIV prevention. In this review, we discuss important considerations for the design and interpretation of cluster randomized controlled trials (C-RCTs of combination prevention interventions. We focus on three large C-RCTs that will start soon and are designed to test the hypothesis that combination prevention packages, including expanded access to antiretroviral therapy, can substantially reduce HIV incidence. Using a general framework to integrate mathematical modelling analysis into the design, conduct, and analysis of C-RCTs will complement traditional statistical analyses and strengthen the evaluation of the interventions. Importantly, even with combination interventions, it may be challenging to substantially reduce HIV incidence over the 2- to 3-y duration of a C-RCT, unless interventions are scaled up rapidly and key populations are reached. Thus, we propose the innovative use of mathematical modelling to conduct interim analyses, when interim HIV incidence data are not available, to allow the ongoing trials to be modified or adapted to reduce the likelihood of inconclusive outcomes. The preplanned, interactive use of mathematical models during C-RCTs will also provide a valuable opportunity to validate and refine model projections.

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

Full Text Available Hispanics are the fastest growing minority group in North Carolina with increasing incidence of HIV infection. Gender roles, cultural expectations, and acculturation of women may explain some of Hispanic women’s risks. The perspectives of Hispanic female immigrants and community-based providers were sought to identify services they offer, understand HIV risk factors, and support the adaptation of a best-evidence HIV behavioural intervention for Hispanic women. Two sets of focus groups were conducted to explicate risks and the opportunities to reach women or couples and the feasibility to conduct HIV prevention in an acceptable manner. Salient findings were that Hispanic female immigrants lacked accurate HIV/AIDS and STI knowledge and that traditional gender roles shaped issues surrounding sexual behaviour and HIV risks, as well as condom use, partner communication, and multiple sexual partnerships. Intervention implications are discussed such as developing and adapting culturally appropriate HIV prevention interventions for Hispanics that address gender roles and partner communication.

Full Text Available This paper examines the ways in which HIV prevention is understood including “biomedical”, “behavioural”, “structural”, and “combination” prevention. In it I argue that effective prevention entails developing community capacity and requires that public health addresses people not only as individuals but also as connected members of groups, networks and collectives who interact (talk, negotiate, have sex, use drugs, etc. together. I also examine the evaluation of prevention programmes or interventions and argue that the distinction between efficacy and effectiveness is often glossed and that, while efficacy can be evaluated by randomized controlled trials, the evaluation of effectiveness requires long-term descriptive strategies and/or modelling. Using examples from a number of countries, including a detailed account of the Australian HIV prevention response, effectiveness is shown to be dependent not only on the efficacy of the prevention technology or tool but also on the responses of people – individuals, communities and governments – to those technologies. Whether a particular HIV prevention technology is adopted and its use sustained depends on a range of social, cultural and political factors. The paper concludes by calling on biomedical and social scientists to work together and describes a “social public health”.

Objective To determine factors associated with HIV status unawareness and assess HIV prevention knowledge and condom use among people living with HIV/AIDS (PLHIV) in Mozambique. Design Cross-sectional household-based nationally representative AIDS Indicator Survey. Methods Analyses focused on HIV-infected adults and were weighted for the complex sampling design. We identified PLHIV who had never been tested for HIV or received their test results prior to this survey. Logistic regression was used to assess factors associated with HIV status unawareness. Results Of persons with positive HIV test results (N = 1182), 61% (95% confidence interval [CI] 57–65%) were unaware of their serostatus. Men had twice the odds of being unaware of their serostatus compared with women [adjusted odds ratio (aOR) 2.05, CI 1.40–2.98]. PLHIV in the poorest wealth quintile were most likely to be unaware of their serostatus (aOR 3.15, CI 1.09–9.12) compared to those in the middle wealth quintile. Most PLHIV (83%, CI 79–87%) reported not using a condom during their last sexual intercourse, and PLHIV who reported not using a condom during their last sexual intercourse were more likely to be unaware of their serostatus (aOR 2.32, CI 1.57–3.43) than those who used a condom. Conclusions Knowledge of HIV-positive status is associated with more frequent condom use in Mozambique. However, most HIV-infected persons are unaware of their serostatus, with men and persons in the poorest wealth quintile being more likely to be unaware. These findings support calls for expanded HIV testing, especially among groups less likely to be aware of their HIV status and key populations at higher risk for infection. PMID:25222010

Compared to White women, Latinas are 4 times more likely to contract HIV. In an effort to determine the overall state of the science meant to address this disparity, we reviewed the current HIV prevention intervention literature for U.S. Latinas. We searched 5 online electronic databases from their inception through July, 2014, for HIV prevention interventions including a majority sample of Latinas. Of 1041 articles identified, 20 studies met inclusion criteria. We documented study designs, participant characteristics, outcomes, theories used, and other intervention characteristics. Overall, HIV knowledge and attitudes were the predominant outcome; a small minority of studies included self-reported condom use or STD incidence. Strategies used to address cultural factors specific to Latinas and HIV included; lay health advisors, using ethnographic narratives, or using the Theory of Gender and Power, however few of the interventions adopted these strategies. This study identified several gaps in the intervention literature that need to be addressed. In addition to including more direct measures of decreased HIV risk (ex. condom use), more systematic use of strategies meant to address gender and cultural factors that may place Latinas at increased risk (e.g., gender inequity, traditional gender role norms such as machismo and marianismo, and relationship power dynamics).

Recently, behavioral prevention interventions for HIV have been criticized as being ineffective, costly, or inefficient. In this commentary, using HIV-positive men who have sex with men (MSM) as an illustrative high-risk population, we argue that the opposite is true – that behavioral interventions for HIV prevention, if implemented with the populations who need them, are affordable and critical for future prevention efforts. We base this argument on recent evidence showing that 1) adherence ...

This article explores how notions of the individual and population are evoked in two ongoing HIV treatment as prevention (TasP) implementation studies in Swaziland. By contrasting policy discourses with lived kinship experiences of people living with HIV, we seek to understand how TasP unfolds in the Swazi context. Data collection consisted of eight focus group discussions with people living with HIV who were members of support groups to examine their perspectives about TasP. In addition, 18 key informant interviews were conducted with study team members, national-level policy-makers and NGO representatives involved in the design of health communication messages about TasP in Swaziland. Thematic analysis was used to identify recurrent themes in transcripts and field notes. Policy-makers and people living with HIV actively resisted framing HIV treatment as a prevention technology but promoted it as (earlier) access to treatment for all. TasP was not conceptualised in terms of individual or societal benefits, which are characteristic of international public health debates; rather its locally situated meanings were embedded in kinship experiences, concerns about taking responsibility for one's own health and others, local biomedical knowledge about drug resistance, and secrecy. The findings from this study suggest that more attention is needed to understand how the global discourse of TasP becomes shaped in practice in different cultural contexts.
Full Text Available Couples' voluntary HIV counseling and testing (CVCT significantly decreases HIV transmission within couples, the largest risk group in sub-Saharan Africa, but it is not currently offered in most HIV testing facilities. To roll out such an intervention, understanding locale-specific knowledge barriers is critical. In this study, we measured knowledge of HIV serodiscordance, transmission, and prevention before and after receipt of CVCT services in Durban.Pre- and post-CVCT knowledge surveys were administered to a selection of individuals seeking CVCT services.Changes in knowledge scores were assessed with McNemar Chi-square tests for balanced data and generalized estimating equation methods for unbalanced data.The survey included 317 heterosexual black couples (634 individuals who were primarily Zulu (87%, unemployed (47%, and had at least a secondary level education (78%. 28% of couples proved to be discordant. Only 30% of individuals thought serodiscordance between couples was possible pre-CVCT compared to 95% post-CVCT. One-third thought there was at least one benefit of CVCT pre-CVCT, increasing to 96% post-CVCT. Overall, there were positive changes in knowledge about HIV transmission and prevention. However, many respondents thought all HIV positive mothers give birth to babies with AIDS (64% pre-CVCT, 59% post-CVCT and that male circumcision does not protect negative men against HIV (70% pre-CVCT, 67% post-CVCT.CVCT was well received and was followed by improvements in understanding of discordance, the benefits of joint testing, and HIV transmission. Country-level health messaging would benefit from targeting gaps in knowledge about serodiscordance, vertical transmission, and male circumcision.

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.

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

Stigma, voicelessness, and legislative and rights barriers, coupled with top-down decision making, are the common experiences of vulnerable youth populations that limit their opportunities to participate in vital health promotion efforts such as HIV prevention. To consider new opportunities arising from a digital society for youth to creatively shape HIV prevention. Drawing on research with vulnerable youth in Busoga, Uganda; Bulawayo, Zimbabwe; Bangkok, Thailand; and Bali, Indonesia, we explore current youth participation, in theory and practice, while considering new opportunities arising from a digital society for youth to creatively shape HIV prevention. Collaborative commons and prosumer models are defined as people employing new technology to codesign toward a common goal. Within the context of a diminishing role of the traditional institution and the rise of digitized networks, such models offer exciting new directions for youth as electronic health promotion prosumers to participate in difficult challenges such as HIV prevention in the 21st century. It is time for institutions to embrace such opportunities, especially in areas where access to technology is widening, while continuing to champion youth and advocate for supportive social environments.

Mobile phone applications (apps) provide a new platform for delivering tailored human immunodeficiency virus (HIV) and sexually transmitted disease (STD) prevention and care. To identify and evaluate currently available mobile phone apps related to the prevention and care of HIV and other STDs. We searched the Apple iTunes and Android Google Play stores for HIV/STD-related apps, excluding apps that exclusively targeted industry, providers, and researchers. Each eligible app was downloaded, tested, and assessed for user ratings and functionality as well as 6 broad content areas of HIV prevention and care: HIV/STD disease knowledge, risk reduction/safer sex, condom promotion, HIV/STD testing information, resources for HIV-positive persons, and focus on key populations. Search queries up to May 2012 identified 1937 apps. Of these, 55 unique apps met the inclusion criteria (12 for Android, 29 for iPhone, and 14 for both platforms). Among these apps, 71% provided disease information about HIV/STDs, 36% provided HIV/STD testing information or resources, 29% included information about condom use or assistance locating condoms, and 24% promoted safer sex. Only 6 apps (11%) covered all 4 of these prevention areas. Eight apps (15%) provided tools or resources specifically for HIV/STD positive persons. Ten apps included information for a range of sexual orientations, 9 apps appeared to be designed for racially/ethnically diverse audiences, and 15 apps featured interactive components. Apps were infrequently downloaded (median 100-500 downloads) and not highly rated (average customer rating 3.7 out of 5 stars). Most available HIV/STD apps have failed to attract user attention and positive reviews. Public health practitioners should work with app developers to incorporate elements of evidence-based interventions for risk reduction and improve app inclusiveness and interactivity.

Full Text Available BACKGROUND: Through major efforts to reduce costs and expand access to antiretroviral therapy worldwide, widespread delivery of effective treatment to people living with HIV/AIDS is now conceivable even in severely resource-constrained settings. However, the potential epidemiologic impact of treatment in the context of a broader strategy for HIV/AIDS control has not yet been examined. In this paper, we quantify the opportunities and potential risks of large-scale treatment roll-out. METHODS AND FINDINGS: We used an epidemiologic model of HIV/AIDS, calibrated to sub-Saharan Africa, to investigate a range of possible positive and negative health outcomes under alternative scenarios that reflect varying implementation of prevention and treatment. In baseline projections, reflecting "business as usual," the numbers of new infections and AIDS deaths are expected to continue rising. In two scenarios representing treatment-centered strategies, with different assumptions about the impact of treatment on transmissibility and behavior, the change in the total number of new infections through 2020 ranges from a 10% increase to a 6% reduction, while the number of AIDS deaths through 2020 declines by 9% to 13%. A prevention-centered strategy provides greater reductions in incidence (36% and mortality reductions similar to those of the treatment-centered scenarios by 2020, but more modest mortality benefits over the next 5 to 10 years. If treatment enhances prevention in a combined response, the expected benefits are substantial-29 million averted infections (55% and 10 million averted deaths (27% through the year 2020. However, if a narrow focus on treatment scale-up leads to reduced effectiveness of prevention efforts, the benefits of a combined response are considerably smaller-9 million averted infections (17% and 6 million averted deaths (16%. Combining treatment with effective prevention efforts could reduce the resource needs for treatment dramatically

Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusion 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.

Full Text Available 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

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.
Antiretroviral drugs are primarily used to treat people living with HIV but can also reduce the risk of transmission. The first application of this prophylactic approach was in the prevention of mother-to-child transmission, which comprises three components: 1) antiretroviral therapy during pregnancy to reduce maternal viral load, 2) pre-exposure prophylactic treatment of the fetus in utero and intrapartum, and 3) postexposure neonatal treatment. This has resulted in a sharp reduction in mother-to-child transmission, to well below 1 % in France today. "Treatment as prevention" (TASP) is now widely recommended to prevent sexual transmission to partners of people living with HIV articularly when a couple wishes to have children. Achieving and sustaining undetectable viral load is an important means of reducing the risk of sexual transmission in serodiscordant couples and also of controlling the pandemic worldwide. The other uses of antiretroviral drugs to protect HIV-negative people at risk include post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP). Prevention has both individual and collective dimensions and involves several components, including behavioral changes, serological testing, and use of antiretrovirals.

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.

To obtain a thorough understanding of the complexity and dynamics of the social determination of HIV infection among inhabitants of Cartagena, Colombia, as well as their views on necessary actions and priorities. In a five-year ethnography of HIV/AIDS in collaboration with 96 citizens of Cartagena, different methods and data collection techniques were used. Through 40 in-depth interviews and 30 life histories of inhabitants, the scenario of HIV vulnerability was summarized in a diagram. This diagram was evaluated and complemented through group discussions with key representatives of local governmental and nongovernmental organizations and with people who were interested in the epidemic or affected by it. The diagram illustrates the dynamic and complex interrelationships among structural factors (i.e., social determinants) of HIV infection, such as machismo; lack of work, money, and social services; local dynamics of the performance of the state; and international dynamics of the sexual tourism industry. On the basis of the diagram, groups of key representatives proposed prioritizing structural actions such as reducing socioeconomic inequalities and providing access to health care and education. The social determinants displayed in the diagram relate to historic power forces that have shaped vulnerable scenarios in Cartagena. Collaboration between participants and researchers generates conceptual frameworks that make it possible to understand and manage the complexity of HIV's social determination. This way of understanding effectively connects local inequalities with international flows of power such as sexual tourism and makes evident the strengths and limitations of current approaches to HIV prevention.
In recent years, HIV/AIDS programming has been transformed by an ostensibly 'new' procedure: male circumcision. This article examines the rise of male circumcision as the 'right' HIV prevention tool. Treating this controversial topic as a 'matter of concern' rather than a 'matter of fact', I examine the reasons why male circumcision came to be seen as a partial solution to the problem of HIV transmission in the twenty-first century and to what effect. Grounded in a close reading of the primary literature, I suggest that the embrace of male circumcision in HIV prevention must be understood in relation to three factors: (1) the rise of evidence-based medicine as the dominant paradigm for conceptualising medical knowledge, (2) the fraught politics of HIV/AIDS research and funding, which made the possibility of a biomedical intervention attractive and (3) underlying assumptions about the nature of African 'culture' and 'sexuality'. I conclude by stressing the need to expand the parameters of the debate beyond the current polarised landscape, which presents us with a problematic either/or scenario regarding the efficacy of male circumcision.

Conditional cash transfers (CCT) have recently received considerable attention as a potentially innovative and effective approach to the prevention of HIV/AIDS. We evaluate a conditional cash transfer program in rural Malawi which offered financial incentives to men and women to maintain their HIV status for approximately one year. The amounts of the reward ranged from zero to approximately 3-4 months wage. We find no effect of the offered incentives on HIV status or on reported sexual behavior. However, shortly after receiving the reward, men who received the cash transfer were 9 percentage points more likely and women were 6.7 percentage points less likely to engage in risky sex. Our analyses therefore question the "unconditional effectiveness" of CCT program for HIV prevention: CCT Programs that aim to motivate safe sexual behavior in Africa should take into account that money given in the present may have much stronger effects than rewards offered in the future, and any effect of these programs may be fairly sensitive to the specific design of the program, the local and/or cultural context, and the degree of agency an individual has with respect to sexual behaviors.

Full Text Available Liver transplantation is a life-saving procedure with demonstrated utility. There are accumulating data indicating that this procedure is helpful in HIV-infected patients as well. Liver transplantation is currently largely unavailable to those living with HIV in Canada. Understanding the obstacles to this procedure is the first step to increasing access. Between August 2005 and November 2005, HIV physicians, one from each Canadian HIV Trials Network site, were asked to complete a quantitative questionnaire on adult liver transplant access and need. Forty-six per cent (16 of 35 of sites responded. A median 20% of the nearly 12,700 HIV patients followed at these sites had concurrent liver disease (20% caused by hepatitis C virus, 5% caused by hepatitis B virus and 5% were alcohol-related. On average, two patients per site were thought to be appropriate candidates for liver transplant evaluation. Eighty per cent of respondents anticipated increased need for liver transplantation over the next five years. Organ supply was universally identified as the chief obstacle to transplantation in patients with HIV. Other key issues included risk of hepatitis C virus reinfection and transplant surgical team willingness. Based on these data, it is believed that these issues should be the focus of efforts designed to increase access to transplantation in Canadians with end-stage liver disease and concurrent HIV.

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

Three decades after the first reported cases of AIDS we have within our reach sufficient evidence to substantially alter the HIV epidemic at a country level regardless of mode of transmission of HIV. There are a growing number of countries demonstrating control of the epidemic. Human rights violations and/or legislation relating to sexual orientation, status of minors, injecting drug use and sex work together with stigma and discrimination remain key barriers to knowledge of HIV status and access to appropriate services. The use of anti-retrovirals prophylactically to reduce sexual and vertical transmission and systemically to treat infected infants and adults is central to the optimism in responses to the epidemic. In the current fiscal climate careful thought needs to be given to how to efficiently optimise combinations of what is available to have the biggest impact in the context of limited human and infrastructure resources.

Interest in the use of antiretroviral therapy (ART) for prevention stems from mounting evidence from research studies demonstrating that ART is associated with a decrease in sexual HIV transmission among serodiscordant couples and, perhaps, in other populations at risk. There is paucity of data on the efficacy of ART for prevention in key populations, including persons who inject drugs (PWID). In this paper, we examine the current status of HIV services for PWID in Central Asia, the use of ART by this population and explore ART for prevention for PWID in this context. We also discuss research and implementation questions with relevance to such a strategy in the region.

New HIV diagnoses among men having sex with men (MSM) have not decreased appreciably in most countries, even though care and prevention services have been scaled up substantially in the past 20 years. To maximize the impact of prevention strategies, it is crucial to quantify the sources of transmission at the population level. We used viral sequence and clinical patient data from one of Europe's nationwide cohort studies to estimate probable sources of transmission for 617 recently infected MSM. Seventy-one percent of transmissions were from undiagnosed men, 6% from men who had initiated antiretroviral therapy (ART), 1% from men with no contact to care for at least 18 months, and 43% from those in their first year of infection. The lack of substantial reductions in incidence among Dutch MSM is not a result of ineffective ART provision or inadequate retention in care. In counterfactual modeling scenarios, 19% of these past cases could have been averted with current annual testing coverage and immediate ART to those testing positive. Sixty-six percent of these cases could have been averted with available antiretrovirals (immediate ART provided to all MSM testing positive, and preexposure antiretroviral prophylaxis taken by half of all who test negative for HIV), but only if half of all men at risk of transmission had tested annually. With increasing sequence coverage, molecular epidemiological analyses can be a key tool to direct HIV prevention strategies to the predominant sources of infection, and help send HIV epidemics among MSM into a decisive decline.

Since HIV-1 was identified, development of a preventive vaccine has been a major goal. Significant progress toward that goal has been made by 2010. In macaques, a vigorous T effector cell response has protected some animals from disease caused by simian immunodeficiency virus (SIV). Broadly, neutralizing human anti-HIV antibodies have been isolated and their structures, and targets are rapidly being elucidated. For the first time an AIDS vaccine has shown modest protective efficacy in a human clinical trial. To reach the final goal, there is a need for a coordinated global effort, including a range of approaches including novel high-throughput screening techniques, X-ray crystallography, and monoclonal antibody isolation, analysis of T cell responses and their impact on disease progression, human epidemiology, as well as targeted studies in nonhuman primates. African research teams as well as cohorts of healthy volunteers and HIV-infected individuals have contributed to HIV vaccine research and development in many important ways. It is essential that this work continue to speed the development and deployment of a vaccine suitable for African populations.

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.

避孕套在安全性行为中起到至关重要的作用,它既可避孕,又可预防艾滋病。但最近一项研究表明,它的功效远远不止如此:People who consistentlyused condoms got fewer cases of gonorrhea and chlamydia than those who usedthem only occasionally.Condoms also prevented transmission of genital herpes inmen and possibly in women,too.
Full Text Available The use of videogames interventions is becoming an increasingly popular and effective strategy in disease prevention and health promotion; however, few health videogame interventions have been scientifically rigorously evaluated for their efficacy. Moreover, few examples of the formative process used to develop and evaluate evidence-based health videogame interventions exist in the scientific literature. The following paper provides valuable insight into the lessons learned during the process of developing the risk reduction and HIV prevention videogame intervention for young adolescents, PlayForward: Elm City Stories.

In light of the great threat that HIV/AIDS poses in sub-Saharan Africa, the current study assesses HIV/AIDS posters from this region with specific reference to health message frames, including HIV sources, consequences, self-efficacy, preventive means, and barriers and benefits to employing such means of prevention. There is a two-step methodology. First, the content of HIV/AIDS posters from 15 sub-Saharan African countries was coded for the six health message frames. Second, relationships between the health message frames and four social determinants (HIV rate, HIV awareness, condom use and uncertainty avoidance (UAI)) were assessed with hierarchical linear modeling (HLM). Analysis indicates that self-efficacy is the most common frame, but that almost one-quarter of the posters has none of the six health message frames. HLM indicates some favorable findings, including that health message frames are used most often in countries with the most troubling levels of HIV awareness and condom use. Less favorably, health message frames are used least common in countries that have high levels of UAI and high HIV rates. Improvements for related media practices and policy are articulated.

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

Despite many recent advances in the HIV prevention landscape, an effective vaccine remains the most promising tool to end the HIV-1 pandemic. Areas covered: This review summarizes past HIV vaccine efficacy trials and current vaccine strategies as well as new approaches about to move into first-in-human trials. Expert opinion: Despite many setbacks in early HIV vaccine efficacy trials, the success of RV144 has provided the glimmer of hope necessary to invigorate the vaccine field, and has led to the development of a large number of vaccine strategies aiming at inducing an array of different immune responses. The follow-up pox-protein trials, developed to replicate and enhance the polyfunctional antibody responses induced by the RV144 regimen, are already reaching efficacy trials, while a large body of work providing a more complete understanding of the development of broadly neutralizing antibodies is now being translated into immunogen design using several different strategies. T-cell based vaccines, fallen out of favor after Ad5-based trials showed increased infection rates in Ad5 seropositive vaccine recipients, are experiencing a comeback based in part on the promising results from non-human primate challenge studies using rhCMV-based immunogens. This diverse array of vaccine candidates may finally allow us to identify a broadly effective HIV vaccine able to contain the epidemic.

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

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

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

HIV and sexually transmitted human papillomavirus (HPV) are associated with each other and with the development of comorbid cancer. Current epidemiology indicates that among Pacific Islanders in the United States, young adults are at highest risk of HIV and HPV. In our inductive community based participatory research study, we used focus groups and key informant interviews (March-August 2010) with young adults, parents, community leaders, and providers (n = 95) to identify and contextualize factors that shape HIV and HPV risk and prevention among young adults in Chamorro and Tongan communities in Southern California. We identified nine themes that incorporated the following principal factors: misinformation and otherization; dominant concerns regarding premarital pregnancy; restricted intergenerational communication; family shame and privacy; gendered manifestations of religio-cultural norms; barriers impeding access to sexual health resources; parents' role in prevention; community vs. individual responsibility; and family and ethnic pride. Our thematic findings fit well with Rhodes' "risk and enabling environment" heuristic (2009), which we used to contextualize risk and prevention at micro and macro levels of physical, social, economic, and policy environments. We propose the addition of a separate cultural environment to the heuristic and conclude that a focus on applying individual and community agency at the micro-level would be an approachable starting point for intervention for our local Pacific Islander communities and groups in similar ecological contexts globally. Enhanced community-led education programs and engagement of religious and other community leaders to facilitate intergenerational communication could counteract taboos that obstruct prevention.

Full Text Available BACKGROUND: After the first two cases of locally-acquired HIV infection were recognized in Chuuk State, Federated States of Micronesia (FSM, a public health response was initiated. The purpose of the response was to assess the need for HIV education and prevention services, to develop recommendations for controlling further spread of HIV in Chuuk, and to initiate some of the prevention measures. METHODOLOGY/PRINCIPAL FINDINGS: A public health team conducted a survey and rapid HIV testing among a sample of residents on the outer islands in Chuuk. Local public health officials conducted contact tracing and testing of sex partners of the two locally-acquired cases of HIV infection. A total of 333 persons completed the survey. The majority knew that HIV is transmitted through unprotected sexual contact (81%, injection drug use (61%, or blood transfusion (64%. Sexual activity in the past 12 months was reported among 159 participants, including 90 females and 69 males. Compared to women, men were more likely to have had multiple sex partners, to have been drunk during sex, but less likely to have used a condom in the past 12 months. The two men with locally acquired HIV infection had unprotected anal sex with a third Chuukese man who likely contracted HIV while outside of Chuuk. All 370 persons who received voluntary, confidential HIV counseling and testing had HIV negative test results. CONCLUSIONS/SIGNIFICANCE: Despite the low HIV seroprevalence, risky sexual behaviors in this small isolated population raise concerns about the potential for rapid spread of HIV. The lack of knowledge about risks, along with stigmatizing attitudes towards persons infected with HIV and high risk sexual behaviors indicate the need for resources to be directed toward HIV prevention in Chuuk and on other Pacific Islands.

To be effective, HIV/AIDS interventions must be culturally and linguistically appropriate and must occur within the context of the specific community in which they are delivered. In this article, the development of a culture-specific lay health advisor (LHA) program, Protegiendo Nuestra Comunidad, for recently immigrated Mexicans is described. This program is one component of a collaborative inquiry research project involving community participants and researchers working as partners in carrying out and assessing a program for the prevention of HIV/AIDS. The collaborative inquiry process was applied as an empowerment philosophy and methodology of Paulo Freire and an ecological framework was used for the development of Protegiendo Nuestra Comunidad. The use of principles of empowerment for curriculum development, teaching methodology, and program delivery are described.

Social marketing involves applying marketing principles to promote social goods. In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide.

To ascertain the cost effectiveness of targeted interventions for female sex workers (FSW) under the National AIDS Control Programme in India. A compartmental mathematical Markov state model was used over a 20-year time horizon (1995-2015) to estimate the cost effectiveness of FSW targeted interventions, with a health system perspective. The incremental costs and effects of FSW targeted interventions were compared against a baseline scenario of mass media for the general population alone. The incremental cost-effectiveness ratio was computed at a 3% discount rate using HIV infections averted and disability-adjusted life-years (DALY) as benefit measures. It was assumed that the transmission of the HIV virus moves from a high-risk group (FSW) to the client population and finally to the general population (partners of clients). Targeted interventions for FSW result in a reduction of 47% (1.6 million) prevalent and 36% (2.7 million) cumulative HIV cases, respectively, in 2015. Adult HIV prevalence in India, with and without (mass media only) FSW interventions, would be 0.25% and 0.48% in 2015. Indian government and development partners spend an average US $104 (INR4680) per HIV infection averted and US $10.7 (INR483) per DALY averted. Discounting at 3%, FSW targeted interventions cost US $105.5 (INR4748) and US $10.9 (INR490) per HIV case and DALY averted, respectively. At the current gross domestic product in India, targeted intervention is a cost-effective strategy for HIV prevention in India.
Data suggest that HIV prevalence rates among Muslim populations may be increasing due to unprotected sexual intercourse and shared injection equipment, despite popular belief that adherence to religious injunctions has shielded Muslim populations from the HIV epidemic. HIV prevention programs targeting Muslim populations to date have often lacked a theoretical foundation and have neglected the important Islamic concept of jihad, or struggle. This article reviews the cultural and religious factors that may facilitate or reduce HIV risk in Muslim communities. The theory of reasoned action and a harm reduction approach are utilized to demonstrate how the important concept of jihad can be integrated with HIV prevention theory to develop HIV prevention approaches at individual and structural levels. The proposed approach to HIV prevention must be validated, refined, and evaluated for specific cultures and locales through field testing.

Full Text Available Mid-way through the third decade of experience in preventing HIV/AIDS among adolescents, behavioral interventions and outcomes for high risk subgroups have generated evidence extremely instructive for navigating future priorities in reducing transmission risk behavior. Youth who abuse alcohol or drugs, who are detained or incarcerated, or have mental health co-morbidity such as externalizing disorders, represent the most significant challenge to current and future efforts to control the epidemic among the adolescent population. Although there is no unambiguous, standard intervention approach with adolescents, patterns of risks and outcomes with these subgroups are instructive in the critical priority of creating more sustainable gains with our HIV prevention resources. This article provides a synthesis of the evidence with these subgroups, discusses important limitations and difficulties in the current intervention science and highlights promising directions for the next generation of effort in reducing adolescent HIV-related sexual risk behavior. Because individual-level interventions have had only modest effects, a key current emphasis within the field is to develop multi-level interventions with a more ecological or contextual focus. We review various pragmatic responses that acknowledge this priority and the debt owed to individual-level intervention work with adolescents.

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.

The use antiretroviral reduces the sexual transmission of HIV, expanding interventions for serodiscordant couples. This article aims to review the use of antiretroviral and other prevention interventions among serodiscordant couples and to analyze its use in Brazil. A retrospective review was performed through the MEDLINE database and bases included in the Biblioteca Virtual em Saúde. The articles recovered exhibit four main strategies: (1) condom; (2) reduction of risks in sexual practices; (3) use of antiretrovirals, particularly early initiation of antiretroviral therapy (TASP) and pre-exposure prophylaxis (PrEP); (4) risk reduction in reproduction. TASP is highly effective in reducing sexual transmission, PrEP was tested in serodiscordant couples and both reduce the sexual transmission risk in different sexual practices, enabling individualized prevention strategies. When used in combination, antiretrovirals and sexual practices with condoms offer greater efficacy than any single strategy. The combined use of new and old strategies allows us to build a prevention policy for all.

Novel methods, such as Internet-based interventions, are needed to combat the spread of HIV. While past initiatives have used the Internet to promote HIV prevention, the growing popularity, decreasing digital divide, and multi-functionality of social networking sites, such as Facebook, make this an ideal time to develop innovative ways to use online social networking sites to scale HIV prevention interventions among high-risk groups. The UCLA Harnessing Online Peer Education study is a longitudinal experimental study to evaluate the feasibility, acceptability, and preliminary effectiveness of using social media for peer-led HIV prevention, specifically among African American and Latino Men who have Sex with Men (MSM). No curriculum currently exists to train peer leaders in delivering culturally aware HIV prevention messages using social media. Training was created that adapted the Community Popular Opinion Leader (C-POL) model, for use on social networking sites. Peer leaders are recruited who represent the target population and have experience with both social media and community outreach. The curriculum contains the following elements: discussion and role playing exercises to integrate basic knowledge of HIV/AIDS, awareness of sociocultural HIV/AIDS issues in the age of technology, and communication methods for training peer leaders in effective, interactive social media-based HIV prevention. Ethical issues related to Facebook and health interventions are integrated throughout the sessions. Training outcomes have been developed for long-term assessment of retention and efficacy. This is the first C-POL curriculum that has been adapted for use on social networking websites. Although this curriculum has been used to target African-American and Latino MSM, it has been created to allow generalization to other high-risk groups.
A total 494 cases of AIDS had been reported to the Ministry of Health and Family Welfare in India by October 31, 1993. Tamil Nadu and Maharashtra have the highest number of cases at 152 and 117 respectively, Kerala has 76, Punjab/Chandigarh 47, and Delhi 42, while the other states reported 1-17. More than 90% of cases were in the 15-45 year-old age group. Multipartner sex probably accounts for 80% of infections, blood and blood product transfusions for 12%, and sharing unsterilized drug injecting equipment for 5%. This number of reported cases, however, represents only a small fraction of actual AIDS morbidity in India due to general underreporting; the actual number of AIDS cases is probably in the range of 10,000-20,000 thousand. As for HIV infection, 13,448 of the 1,933,834 individuals tested for HIV through the nationwide surveillance network over the period October 1985-October 1993, were found to be infected. The seropositivity rate increased from 2.5/1000 in 1986 to 11.2/1000 by 1992. The author notes, however, that up to 90% of the population groups screened thus far came from high-risk groups. HIV-infected individuals were found in almost all states and Union Territories, although the major concentration of HIV remains in Bombay which may contain 5-10% of the country's infected individuals. Surveillance reports from the commercial sex workers show a marked rise in HIV prevalence from 10% in 1986 to 32% in 1991. Other hot spots are Pune, Madras, Madurai, and Vellore. The latest studies have shown HIV infection among IV drug users to be 74% in Manipur, 50% in Nagaland, and 6-10% in Mizoram. More than 1.5 million people were estimated to have been infected by the end of 1993. Lack of information from rural and semi-urban areas, however, does not allow estimates and projections beyond the major municipal centers. The author warns that current conditions of HIV infection and AIDS in India strongly resemble those in certain regions of Africa in the 1980s after
Full Text Available HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported in African fishing villages, local distribution patterns of HIV infection in the communities surrounding these villages have not been thoroughly analyzed. The objective of this study was to investigate the geographical distribution patterns of HIV infection in communities surrounding African fishing villages. In 2011, we applied age- and sex-stratified random sampling to collect 1,957 blood samples from 42,617 individuals registered in the Health and Demographic Surveillance System in Mbita, which is located on the shore of Lake Victoria in western Kenya. We used these samples to evaluate existing antibody detection assays for several infectious diseases, including HIV antibody titers. Based on the results of the assays, we evaluated the prevalence of HIV infection according to sex, age, and altitude of participating households. We also used Kulldorff's spatial scan statistic to test for HIV clustering in the study area. The prevalence of HIV at our study site was 25.3%. Compared with the younger age group (15-19 years, adults aged 30-34 years were 6.71 times more likely to be HIV-positive, and the estimated HIV-positive population among women was 1.43 times larger than among men. Kulldorff's spatial scan statistic detected one marginally significant (P = 0.055 HIV-positive and one significant HIV-negative cluster (P = 0.047 in the study area. These results suggest a homogeneous HIV distribution in the communities surrounding fishing villages. In addition to individual behavior, more complex and diverse factors related to the social and cultural environment can contribute to a homogeneous distribution pattern of HIV infection outside of African fishing villages. To reduce rates of transmission in HIV-endemic areas, HIV prevention and control programs optimized for the local environment need to be developed.

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

Full Text Available Universal HIV testing and immediate antiretroviral therapy for infected individuals has been proposed as a way of reducing the transmission of HIV and thereby bringing the HIV epidemic under control. It is unclear whether transmission during early HIV infection--before individuals are likely to have been diagnosed with HIV and started on antiretroviral therapy--will compromise the effectiveness of treatment as prevention. This article presents two opposing viewpoints by Powers, Miller, and Cohen, and Williams and Dye, followed by a commentary by Fraser.

Full Text Available The Black Church has long been purported as being strongly influential in the lives of Blacks in America. Recent U.S. census data trends highlight a “reverse migration” pattern where Blacks are moving back to the South from larger metropolitan areas in other U.S. geographical regions. This migration pattern parallels the increasing HIV/AIDS prevalence among Blacks in the Deep South. This paper reviews both the historical and current migration patterns among Blacks, as well as the current HIV/AIDS epidemic among Blacks in the Deep South. Thereafter, the authors discuss an existing framework for increasing HIV/AIDS prevention capacity through a conceptual connection of migration, religion and sexual health. The authors use case studies to support the proposed framework. It is hoped that the framework could be used to address HIV/AIDS health disparities and other chronic diseases affecting Blacks in America.

To evaluate preexposure prophylaxis (PrEP) efficacy for HIV-1 prevention among women using depot medroxyprogesterone acetate (DMPA) for contraception and men whose HIV-1-infected partners use DMPA. Secondary analysis of data from a randomized placebo-controlled trial of daily oral tenofovir and emtricitabine/tenofovir PrEP among heterosexual Kenyan and Ugandan HIV-1 serodiscordant couples. PrEP efficacy for HIV-1 prevention was compared among HIV-1-uninfected women using DMPA versus no hormonal contraception and among HIV-1 uninfected men whose HIV-1-infected female partners used DMPA versus no hormonal contraception. Of 4747 HIV-1 serodiscordant couples, 901 HIV-1-uninfected women used DMPA at some point during follow-up, 1422 HIV-1-uninfected women used no hormonal contraception, 1568 HIV-1-uninfected men had female partners who used DMPA, and 2626 men had female partners who used no hormonal contraception. PrEP efficacy estimates for HIV-1 prevention, compared with placebo, were similar among women using DMPA and those using no hormonal contraception (64.7 and 75.5%, adjusted interaction P = 0.65). Similarly, for men whose female partners used DMPA, PrEP efficacy did not differ from men whose partners used no hormonal contraception (90.0 versus 81.7%, adjusted interaction P = 0.52). PrEP is efficacious for HIV-1 prevention among women using DMPA and men whose partners use DMPA, suggesting PrEP could mitigate the potential increased HIV-1 acquisition and transmission risks that have been associated with DMPA use. Women at risk for HIV-1 choosing DMPA could maintain this contraceptive method and add PrEP to achieve prevention of unintended pregnancy and HIV-1.

Full Text Available Uganda’s health care sector is choking with various challenges, such as poor physical infrastructure, inadequate professionals to run the few existing health centers, poor culture of adherence to professional ethical standards by some health care practitioners, shortages of medicines in most government hospitals/health centers, and corruption. Most of the challenges are more endemic in rural areas. It is on the above premise that this article discusses some of the challenges that health centers face in provision of care to the increasing number of HIV/AIDS patients in hard-to-reach rural communities in northern Uganda and the implications of such challenges on the economy. Uganda’s success in the fight against HIV/AIDS in the early 1990s was globally applauded because of its aggressive grassroots behavioral change crusades aimed at reducing the number of sexual partners. The success inspired a wave of financial aid programs from the US government to fight the disease across the developing world. However, the success was short-lived as the rate of HIV/AIDS infection in Uganda is currently rising, with the health care system struggling to provide care for the ballooning number of patients. To contribute to the curtailing cases of new infections, this article discuses the integration of the traditional authority and knowledge system in the national HIV/AIDS care and prevention program along with the biomedical approach currently being used.

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 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.

New prevention options are urgently needed for African-Americans in the United States given the disproportionate impact of HIV/AIDS on this group. This combined with recent evidence supporting the efficacy of computer technology-based interventions in HIV prevention led our research group to pursue the development of a computer-delivered individually tailored intervention for heterosexually active African-Americans—the tailored information program for safer sex (TIPSS). In the current article, we discuss the development of the TIPSS program, including (i) the targeted population and behavior, (ii) theoretical basis for the intervention, (iii) design of the intervention, (iv) formative research, (v) technical development and testing and (vi) intervention delivery and ongoing randomized controlled trial. Given the many advantages of computer-based interventions, including low-cost delivery once developed, they offer much promise for the future of HIV prevention among African-Americans and other at-risk groups.

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

Full Text Available Preventive psychiatry is one of the most ignored subdiscipline of psychiatry, which has got important role to play in the contemporary psychiatry. Mental disorders are very common with lifetime prevalence of about 25%, and tend to be chronic. Due to the stigma associated with mental disorders, lack of awareness, and also lack of adequate mental health resources, nearly 60%–80% of the persons suffering from mental disorders do not access mental health care services. Mental and substance use disorders have been identified as one of the major contributors to the disease-related burden and disability-adjusted life years. In this background, preventive psychiatry has an important role to play in public health sector. Since etiology of most of the mental disorders is not known, it is not possible to follow here the standard model of primary, secondary, and tertiary prevention of public health. A concept of universal, selective, and indicated prevention has been proposed in primary prevention. Preventive approaches in psychiatry focus on evidence-based risk and protective factors, promoting quality of life, reducing stressors, and improving resilience. Such interventions, when planned targeting at specific mental disorders, have a potential to prevent mental disorders. Thus, preventive psychiatry has a crucial role to play in mental health, considering the high prevalence of mental disorders, the associated disability and burden, and a great drain on human resources.

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

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

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.
Full Text Available HIV infection targets at the human in the human body and targeting damage to immune system to compromise the result in hypoimmunity. HIV associated damages to tissues and organs as well as AIDS related infections caused by various pathogens and neoplasms are clinically common. AIDS related diseases are the main cause of death in patients with AIDS. Therefore, early prevention as well as appropriate and immediate treatment against AIDS related diseases play key role in prolonging the survival period and improving quality of life in patients with AIDS. In recent years, medical radiology has gained rapid development, which plays an important role in diagnosing and treating HIV/AIDS related diseases. The findings by medical radiology constitute an important chain of evidence for HIV/AIDS related diseases. Developed from traditional morphological radiology to current functional and molecular radiology, the modern medical radiology is providing a flood of diagnostic information to guide clinical practice. It is expected to provide accurate data for the location of lesions as well as quantitatively and qualitatively radiological diagnosis. Based on the radiological data, the goal of individualized treatment can be achieved.

Full Text Available Black men who have sex with men (MSM in the United States (US are affected by HIV at disproportionate rates compared to MSM of other race/ethnicities. Current HIV incidence estimates in this group are needed to appropriately target prevention efforts.From July 2009 to October 2010, Black MSM reporting unprotected anal intercourse with a man in the past six months were enrolled and followed for one year in six US cities for a feasibility study of a multi-component intervention to reduce HIV infection. HIV incidence based on HIV seroconversion was calculated as number of events/100 person-years. Multivariate proportional hazards modeling with time-dependent covariates was used to identify correlates of HIV acquisition.Of 1,553 Black MSM enrolled, 1,164 were HIV-uninfected at baseline and included in follow-up. Overall annual HIV incidence was 3.0% (95% confidence interval (CI: 2.0, 4.4% and 5.9% among men ≤30 years old (95% CI: 3.6, 9.1%. Men ≤30 years old reported significantly higher levels of sexual risk and were more likely to have a sexually transmitted infection diagnosed during follow-up. Younger men also were more likely to not have a usual place for health care, not have visited a health care provider recently, and to have unmet health care needs. In multivariate analysis, age ≤30 years (hazard ratio (HR: 3.4; 95% CI: 1.4, 8.3 and unprotected receptive anal intercourse with HIV-positive or unknown status partners (HR: 4.1; 95% CI: 1.9, 9.1 were significantly associated with HIV acquisition.In the largest cohort of prospectively-followed Black MSM in the US, HIV incidence was high, particularly among young men. Targeted, tailored and culturally appropriate HIV prevention strategies incorporating behavioral, social and biomedical based interventions are urgently needed to lower these rates.

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

Computer technology-based interventions (CBIs) represent a promising area for HIV prevention behavioral intervention research. Such programs are a compelling prevention option given their potential for broad reach, customized content, and low cost delivery. The purpose of the current article is to provide a review of the state of the literature on CBIs. First, we define CBIs in HIV prevention and highlight the many advantages of such interventions. Next, we provide an overview of what is currently known regarding the efficacy of CBIs in HIV prevention, focusing on two recent meta-analyses of this literature. Finally, we propose an agenda for future directions for research in the area of CBIs, using the RE-AIM model as an organizing guide. We conclude that with the continued growth of computer technologies, opportunities to apply such technologies in HIV prevention will continue to blossom. Further research is greatly needed to advance an understanding of not only how and under what circumstances CBIs can be efficacious, but also how the reach, adoption, implementation, and maintenance of such programs in clinical and community settings can be achieved.

In 2011, over 10.1 million people were held in prisons around the world. HIV prevalence is elevated in prison and this is due to the over representation of people who inject drugs (PWID). Yet HIV prevention programs for PWID are scarce in the prison setting. With a high proportion of drug users and few prevention programs, HIV transmission occurs and sometimes at an alarming rate. This commentary focuses primarily on drug users in prison; their risk behaviours and levels of infection. It also comments on the transmission of HIV including outbreaks and the efforts to prevent transmission within the prison setting. The spread of HIV in prison has substantial public health implications as virtually all prisoners return to the community. HIV prevention and treatment strategies known to be effective in community settings, such as methadone maintenance treatment, needle and syringe programs, condoms and antiretroviral therapy should be provided to prisoners as a matter of urgency.
Full Text Available Background: The Mahalapye district health management team (DHMT conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme.Aim: This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines.Setting: This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana.Methods: This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013.Results: One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19% knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69% were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67% took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89% were HIV DNA PCR negative at 6 weeks. Thirty-two (73% children were given cotrimoxazole prophylaxis between 6 and 8 weeks.Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

More than two-thirds of the 115 pregnant women (69% were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67% took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89% were HIV DNA PCR negative at 6 weeks. Thirty-two (73% children were given cotrimoxazole prophylaxis between 6 and 8 weeks. Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.
Full Text Available BACKGROUND: To design HIV prevention programmes, it is critical to understand the temporal and geographic aspects of the local epidemic and to address the key behaviours that drive HIV transmission. Two methods have been developed to appraise HIV epidemics and guide prevention strategies. The numerical proxy method classifies epidemics based on current HIV prevalence thresholds. The Modes of Transmission (MOT model estimates the distribution of incidence over one year among risk-groups. Both methods focus on the current state of an epidemic and provide short-term metrics which may not capture the epidemiologic drivers. Through a detailed analysis of country and sub-national data, we explore the limitations of the two traditional methods and propose an alternative approach. METHODS AND FINDINGS: We compared outputs of the traditional methods in five countries for which results were published, and applied the numeric and MOT model to India and six districts within India. We discovered three limitations of the current methods for epidemic appraisal: (1 their results failed to identify the key behaviours that drive the epidemic; (2 they were difficult to apply to local epidemics with heterogeneity across district-level administrative units; and (3 the MOT model was highly sensitive to input parameters, many of which required extraction from non-regional sources. We developed an alternative decision-tree framework for HIV epidemic appraisals, based on a qualitative understanding of epidemiologic drivers, and demonstrated its applicability in India. The alternative framework offered a logical algorithm to characterize epidemics; it required minimal but key data. CONCLUSIONS: Traditional appraisals that utilize the distribution of prevalent and incident HIV infections in the short-term could misguide prevention priorities and potentially impede efforts to halt the trajectory of the HIV epidemic. An approach that characterizes local transmission

Introduction: 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. Methods: We conducted a desk review of Global AIDS Response Progress Reports, national strate...
Full Text Available BACKGROUND: Men who have sex with men (MSM are a high-risk group for HIV. Implementation of effective preventive activities is an important way to combat HIV among MSM. However, in Ukraine there is no real HIV prevention policy among MSM and the need for its formulation is still open. MATERIAL AND METHODS: Analysis of legal acts, national reports and other official documents related to HIV prevention among MSM was carried out for Romania, Slovenia, the Netherlands, and Sweden.RESULTS: European countries use various approaches to HIV prevention among MSM: institutional, structural, and media approach.Countries under consideration have fully specified the minimum standard package for HIV prevention among MSM, who are defined as the highest priority group. Distinct strategies for MSM and ways to achieve them are outlined within the national plans and strategies for combating HIV/AIDS (Slovenia, Romania, the Netherlands. The National plan for HIV prevention among MSM will come into action in 2012 in Sweden. Countries, chosen for this study, use the principle of social contract by which the government provides subsidies and grants to nongovernmental organizations (NGOs working with MSM through its specialized health care units (Slovenia, Sweden, and sometimes only for one national NGO (the Netherlands. Outreach is the most common model of NGO’s activities.. In Sweden, MSM can get counseling and HIV testing in specialized HIV clinic for MSM. HIV prevention among MSM is run by representatives of NGOs through dating sites (Slovenia, Romania, through educating MSM and further promotion of healthy lifestyles among their friends. Along with the behavior modification activities, anti-discrimination strategies are used (Sweden, the Netherlands, Slovenia.CONCLUSIONS: Review of the regulatory frameworks, empowerment of NGOs, implementation of the social contract mechanisms, using interactive tools and providing education for MSM can be key points of HIV

Accelerated efforts to end vertical HIV transmission have resulted in a 52% decrease in new infections among children since 2001. However, current approaches to prevent mother-to-child-transmission (PMTCT) assume a linearity and universality. These insufficiently guide clinicians and programmes toward interventions that comprehensively address the varying and changing needs of clients. This results in high levels of loss-to-follow-up at each step of the PMTCT cascade. Current PMTCT approaches must be adapted to respond to the different and complex realities of women, children and families affected by HIV. Drawing on the concept of an 'HIV trajectories,' we screened peer-reviewed literature for promising PMTCT approaches and selected 13 articles for qualitative review when the described intervention involved more than a biomedical approach to PMTCT and mother-child HIV treatment and care. Our qualitative analysis revealed that interventions which integrated elements of the 'HIV trajectories' perspective and built on people living with HIV support/network, community health worker, primary healthcare and early childhood development platforms were successful because they recognized that HIV is an illness, experienced, moderated and managed by numerous factors beyond biomedical interventions alone.On the basis of this review, we call for the adoption of an 'HIV trajectories' perspective that can help assess the comprehensiveness of care provided to women, children and families affected by HIV and can inform the planning and delivery of HIV and related services so that they more adequately respond to the varying needs of clients on different 'HIV trajectories'.

Female sex workers (FSWs) play a key role in HIV/AIDS transmission and their gatekeepers play a crucial role in shaping their behaviors. Limited studies are available on the relationship between FSWs and gatekeepers. In the current study we used an ethnographic approach to examine the dynamic and multidimensional relationship of FSWs and their gatekeepers from the perspectives of both parties. We recruited 38 FSWs and 16 gatekeepers from different types of commercial sex venues in Guangxi, China, and conducted in-depth individual interviews. Our data suggest that FSWs and gatekeepers maintain an interdependent and reciprocal relationship during their business practice, but gatekeepers exert significant influence and control over FSWs. Designing culturally appropriate HIV/STI-prevention programs requires us to take advantage of the unique and crucial roles of gatekeepers. We conclude with a call for structural interventions to protect FSWs' occupational health and safety.
Full Text Available 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
In face of the HIV pandemic that still grows, unsuccessful efforts of developing biomedical control measures or the failure of cognitive-behavioral approach to show sustained social level effectiveness, behavioral strategy is now expected to evolve into a structural prevention ("combination prevention") that involves multiple behavioral goals and multilevel approaches. WYSH Project is a combination prevention project for youth developed through socio-epidemiological approach that integrates epidemiology with social science such as social marketing and mixed method. WYSH Project includes mass education programs for youth in schools and programs for out-of-school youth through cyber network and peer communication. Started in 2002, it expanded nationwide with supports from related ministries and parent-teacher associations and has grown into a single largest youth prevention project in Japan.
Human immunodeficiency virus (HIV) spread to humans from chimpanzees (HIV-1 groups M and N), gorillas (HIV-1 groups P and O), and sooty mangabeys (HIV-2). HIV is spread mainly through blood or body fluids. Subjects can become infected with HIV by sexual contact, needle sharing, blood transfusions, or maternal transmissions as a blood-borne virus or via breast-milk. The incubation period of HIV-1 from infection to the development of AIDS ranges from 8 to 11 years. In the past 3 decades, HIV has caused a great burden to global wealth and health. According to the WHO global health survey, 36.7 million people were infected with HIV, causing 1.1 million deaths in 2015. Since the discovery of HIV-1, many anti-retroviral drugs have been developed. Following the discovery and wide-spread use of anti-retroviral therapy (ART) the life expectancy of HIV infected individuals has substantially increased. By 2015, all major guidelines recommended treating all HIV-infected adults regardless of their CD4 count. Despite effective ART with virological suppression, HIV-associated neurocognitive disorders (HAND), cardiovascular diseases (CVD), metabolic syndrome (MS), bone abnormalities and non-HIV-associated malignancies remain a major complication associated with HIV infection. In this review article, I would like to describe recent ART status and problems in the ART-era.

The objectives of this study were to assess the current status of HIV-related knowledge, attitudes, and behavior (KAB) of employees in the private transport sector in Namibia and to compare companies with established HIV workplace program (WPPs) with those that have recently initiated the implementation of such programs. The study was designed as a cross-sectional questionnaire-based survey. Between January and March 2011, the survey was conducted in the Namibian truck transport sector in six companies of different sizes. The participants were selected randomly from the workforce. Data collection was based on a KAB questionnaire. The range of correct answers to the survey concerning the knowledge of HIV transmission was 67-95%. Twenty percent of the employees had never been tested for HIV. Additionally, risky sexual behaviors were quite prevalent and included having multiple concurrent partners and the use of sex for incentives. This study revealed that drivers and laborers were especially at risk for such behaviors. The employees of companies with established WPPs were tested for HIV more often than those of companies with new WPPs; however, aside from this difference, only minor differences were observed between the two groups. The findings of this study highlight the need for on-going HIV information and prevention campaigns that focus on the special needs of mobile and low-income workers. WPPs should be tailored accordingly and shift their focus to more practical approaches, such as voluntary counseling and testing (VCT), to increase their effectiveness.

Studies on host genomics have revealed the existence of identifiable HIV-1 specific protective factors among infected individuals who remain naturally resistant viraemia controllers with little or no evidence of virus replication. These factors are broadly grouped into those that are immune associated (MHC, chemokines, cytokines, CTLs and others), linked to viral entry (chemokine co-receptors and ligands), act as post-entry restriction elements (TRIM5a, APOBEC3) and those associated with viral replication (cytokines and others). These features have been identified through multiple experimental approaches ranging from candidate gene approaches, genome wide association studies (GWAS), expression analysis in conjunction with functional assays in humans to primate based models. Several studies have highlighted the individual and population level gross differences both in the viral clade sequences as well as host determined genetic associations. This review collates current information on studies involving major histocompatibility complex (MHC) as well as non MHC genes in the context of HIV-1 infection and AIDS involving varied ethnic groups. Special focus of the review is on the genetic studies carried out on the Indian population. Further challenges with regard to therapeutic interventions based on current knowledge have been discussed along with discussion on documented cases of stem cell therapy and very early highly active antiretroviral therapy (HAART) interventions.

Although HIV in the Middle East and North Africa is currently characterized as a low seroprevalence epidemic, there are numerous factors that are present in the region that could prevent—or exacerbate—the epidemic. The time to invest substantially in prevention—and gender-specific prevention in particular—is now. Given that most policy makers do not make gender-specific plans as epidemics progress, our research team—which draws upon expertise from both within and outside the region—worked together to make programmatic and policy suggestions in the Middle East and North Africa region in 5 key areas: (1) gender-specific and gender transformative HIV prevention interventions; (2) access to quality education and improvements in life skills and sex education; (3) economic empowerment; (4) property rights; and (5) antiviolence. In short, this work builds upon many ongoing efforts in the region and elucidates some of the links between gendered empowerment and health outcomes around the world, particularly HIV and AIDS.

Improvements in biomedical technologies, combined with changing social attitudes to sexual minorities, provide new opportunities for HIV prevention among gay and other men who have sex with men (GMSM). The potential of these new biomedical technologies (biotechnologies) to reduce HIV transmission and the impact of HIV among GMSM will depend, in part, on the degree to which they challenge prejudicial attitudes, practices and stigma directed against gay men and people living with HIV (PLHIV). At the structural level, stigma regarding gay men and HIV can influence the scale-up of new biotechnologies and negatively affect GMSM's access to and use of these technologies. At the personal level, stigma can affect individual gay men's sense of value and confidence as they negotiate serodiscordant relationships or access services. This paper argues that maximising the benefits of new biomedical technologies depends on reducing stigma directed at sexual minorities and people living with HIV and promoting positive social changes towards and within GMSM communities. HIV research, policy and programs will need to invest in: (1) responding to structural and institutional stigma; (2) health promotion and health services that recognise and work to address the impact of stigma on GMSM's incorporation of new HIV prevention biotechnologies; (3) enhanced mobilisation and participation of GMSM and PLHIV in new approaches to HIV prevention; and (4) expanded approaches to research and evaluation in stigma reduction and its relationship with HIV prevention. The HIV response must become bolder in resourcing, designing and evaluating programs that interact with and influence stigma at multiple levels, including structural-level stigma.

Poverty and social inequality are significant drivers of the HIV epidemic and are risk factors for acquiring HIV. As such, many individuals worldwide are at risk for new HIV infection, especially young women in East and Southern Africa. By addressing these drivers, social protection programmes may mitigate the impact of poverty and social inequality on HIV risk. There is reason to believe that social protection can be used successfully for HIV prevention; social protection programmes, including cash transfers, have led to positive health outcomes and behaviour in other contexts, and they have been used successfully to promote education and increased income and employment opportunities. Furthermore, cash transfers have influenced sexual behaviour of young women and girls, thereby decreasing sexual risk factors for HIV infection. When HIV outcomes have been measured, several randomised controlled trials have shown that indirectly, cash transfers have led to reduced HIV prevalence and incidence. In these studies, school attendance and safer sexual health were directly incentivised through the cash transfer, yet there was a positive effect on HIV outcomes. In this review, we discuss the growth of social protection programmes, their benefits and impact on health, education and economic potential, and how these outcomes may affect HIV risk. We also review the studies that have shown that cash transfers can lead to reduced HIV infection, including study limitations and what questions still remain with regard to using cash transfers for HIV prevention.

Full Text Available Programs for integration of family planning into HIV care must recognize current practices and desires among clients to appropriately target and tailor interventions. We sought to evaluate fertility intentions, unintended pregnancy, contraceptive and condom use among a cohort of HIV-infected women seeking family planning services within an antiretroviral therapy (ART clinic.200 women completed an interviewer-administered questionnaire during enrollment into a prospective contraceptive study at the Lighthouse Clinic, an HIV/ART clinic in Lilongwe, Malawi, between August and December 2010.Most women (95% did not desire future pregnancy. Prior reported unintended pregnancy rates were high (69% unplanned and 61% unhappy with timing of last pregnancy. Condom use was inconsistent, even among couples with discordant HIV status, with lack of use often attributed to partner's refusal. Higher education, older age, lower parity and having an HIV negative partner were factors associated with consistent condom usage.High rates of unintended pregnancy among these women underscore the need for integ rating family planning, sexually transmitted infection (STI prevention, and HIV services. Contraceptive access and use, including condoms, must be improved with specific efforts to enlist partner support. Messages regarding the importance of condom usage in conjunction with more effective modern contraceptive methods for both infection and pregnancy prevention must continue to be reinforced over the course of ongoing ART treatment.
Full Text Available BACKGROUND: To determine policy implications, this analysis tracks the evolution of HIV/AIDS infection across China to understand current trends and potential risk factors. METHODS AND PRINCIPAL FINDINGS: A retrospective study with spatial analytical model and multilevel spatial models was conducted among 326,157 HIV/AIDS cases reported from 1989-2009. The results indicate that the distribution of HIV/AIDS was clustered at the county level with different directional distributions across China from 2003 to 2009. Compared to 2003, by 2009 there was a 122% increase in HIV cases among rural residents, 294% increase among urban residents, 211% increase among migrants, and 237% increase among permanent residents. The overall proportion of HIV by different routes of transmission showed dramatic changes with a 504% increase in sexual transmission of HIV, 90% decrease in blood/plasma transmission, and 35% decrease in injecting drug user transmission. Sexual transmission was the major transmission route among women (44% and the elderly (59% in men, 44% in women as well as among permanent (36% and urban residents (33%. Among those <65 years old, women increased more than men, but among those ≥ 65 years, men increased more than women. Migrants contributed to the variance of HIV infection between counties but not within counties. The length of highway and urbanization combined with illiteracy were risk factors for HIV/AIDS. CONCLUSIONS/SIGNIFICANCE: Rates of HIV/AIDS among permanent urban residents, particularly women and elderly men, have increased significantly in recent years. To prevent HIV from spreading further among the general population, additional attention should be paid to these populations as well as to migrants.

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

School-based HIV/AIDS science education has the potential to impact students when integrated into the science curriculum. However, this mixed method study shows that school-based HIV/AIDS science education is often not infused into career subjects such as science education but integrated into civics education and taught by teachers who lack the skills, knowledge, and the training in the delivery of effective school HIV/AIDS education. Since science is where biological events take place, it is suggested that HIV/AIDS science merits being taught in the science education classroom. This study took place in nine public middle schools within two school districts in Abidjan, Ivory Coast, one major urban city in the southern region. The study utilized triangulation of multiple data sources---both qualitative and quantitative. To substantiate the claims made in this study, a range of qualitative methods such as field notes and individual interviews with 39 teachers, 63 sixth grade students, 8 school administrators, and 20 community elders were used. For the quantitative portion 140 teachers and 3510 sixth grade students were surveyed. The findings from the study prioritize science education that includes HIV/AIDS science education for all, with emphasis on HIV/AIDS prevention in Ivory Coast. The factors that influence the implementation of HIV/AIDS curricula within the Ivorian sixth grade classrooms are discussed. Interview and survey data from students, teachers, school administrators, and community elders indicate that in the Ivorian school setting, "gerontocratic" cultural influences, religious beliefs, personal cultural beliefs, and time spent toward the discourse on HIV/AIDS have led to HIV/AIDS education that is often insufficient to change either misconceptions about HIV/AIDS or risky practices. It was also found that approaches to teaching HIV/AIDS does not connect with youth cultures. By reframing and integrating current HIV/AIDS curricula into the science
In this article, I report on my decision to undertake a process of elicitation, development, and examination of metaphors for experiences of HIV prevention work in Burma/Myanmar. I cover the theoretical basis to that decision, my rationale for using metaphor elicitation as method when researching the rhetoric and practice of HIV prevention in Burma/Myanmar, the process I used, and some of the resultant metaphors. I also demonstrate that this process resulted in the opening up of a space for talking about HIV prevention that avoided recourse to standard prevention rhetoric, thereby enabling a new and deeper understanding of the gap between this rhetoric and people's actual practice or experience.

There are few peer-reviewed studies of HIV/AIDS-related knowledge, attitudes, beliefs and practices among adolescents in Central America. A population-based cross-sectional survey was conducted among 246 adolescents in León, Nicaragua, where there is reason for concern about a rise in HIV infections. In many respects, León adolescents were typical of those in other Latin American countries, with a mixture of correct and incorrect knowledge about transmission of HIV and sexually transmitted infections, a higher proportion of males than females reporting having had sex or using condoms, and inconsistent condom use. While some sexual attitudes conformed to the ideology of machismo, others did not, providing an opening for prevention interventions. Some dimensions of HIV/AIDS stigma were high, and most adolescents disapproved of same-sex sexual behaviour. Intervention against homosexuality-related stigma is particularly urgent because a concentrated HIV epidemic may be emerging in Nicaragua among men who have sex with men. Personal religious beliefs did not appear to pose a barrier to condom use. In a multivariate model, being out of school was a significant correlate of having had sex and of insufficient HIV/AIDS-related knowledge. Accordingly, HIV prevention interventions must reach adolescents both in and out of school. A multi-component approach to prevention is needed, including programmes based in schools, communities, the mass media and health facilities.

Although HIV is identified as a family disease, the overall response to the global HIV epidemic continues to predominantly focus on individuals. The aim of this qualitative study was to explore how the role of the family in HIV prevention is perceived by community-based stakeholders. Understanding the role of the family within the context of the HIV/AIDS is essential for community/public health nurses. In total, 34 stakeholders participated in the study. Three major categories were identified namely: fostering positive intra-familial relations, utilizing external resources, and barriers to family roles. The study findings have implications for community-based HIV family interventions.

The impact of a professionally facilitated peer group intervention for HIV prevention among 400 low-income Chilean women was examined using a quasiexperimental design. At 3 months postintervention, the intervention group had higher HIV-related knowledge, more positive attitudes toward people living with HIV, fewer perceived condom use barriers, greater self- efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. They did not, however, have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries.
Full Text Available Abstract Substance-using women who exchange sex for money, drugs or shelter as a means of basic subsistence (ie. survival sex have remained largely at the periphery of HIV and harm reduction policies and services across Canadian cities. This is notwithstanding global evidence of the multiple harms faced by this population, including high rates of violence and poverty, and enhanced vulnerabilities to HIV transmission among women who smoke or inject drugs. In response, a participatory-action research project was developed in partnership with a local sex work agency to examine the HIV-related vulnerabilities, barriers to accessing care, and impact of current prevention and harm reduction strategies among women in survival sex work. This paper provides a brief background of the health and drug-related harms among substance-using women in survival sex work, and outlines the development and methodology of a community-based HIV prevention research project partnership. In doing so, we discuss some of the strengths and challenges of community-based HIV prevention research, as well as some key ethical considerations, in the context of street-level sex work in an urban setting.

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.

Full Text Available ABSTRACTIntroduction:The use antiretroviral reduces the sexual transmission of HIV, expanding interventions for serodiscordant couples.Objective:This article aims to review the use of antiretroviral and other prevention interventions among serodiscordant couples and to analyze its use in Brazil.Methods:A retrospective review was performed through the MEDLINE database and bases included in the Biblioteca Virtual em Saúde.Results:The articles recovered exhibit four main strategies: (1 condom; (2 reduction of risks in sexual practices; (3 use of antiretrovirals, particularly early initiation of antiretroviral therapy (TASP and pre-exposure prophylaxis (PrEP; (4 risk reduction in reproduction.Discussion:TASP is highly effective in reducing sexual transmission, PrEP was tested in serodiscordant couples and both reduce the sexual transmission risk in different sexual practices, enabling individualized prevention strategies.Conclusions:When used in combination, antiretrovirals and sexual practices with condoms offer greater efficacy than any single strategy. The combined use of new and old strategies allows us to build a prevention policy for all.

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

Efforts to prevent HIV from becoming widespread among the youth population 15-24 years in Bangladesh are in the early stages. However, conservative religious and cultural norms may curtail the dissemination of needed information about sexuality and condoms. The community-readiness stages model was adopted as a framework for assessing the level of preparedness of community leaders to facilitate planned HIV prevention efforts. Six focus group discussions with three professional groups (teachers, businessmen, drugshop vendors) in Hobiganj district were conducted in late 2005, and a single multi-professional group made up of teachers, imams, and drugshop vendors was convened in early 2007 to assess changes. The audio recordings in Bangla were coded as were English translations. Everyone had heard of AIDS and regarded it as a potential catastrophe for the health, economy and social fabric of Bangladesh. Remarks concerning Stage 1-Vulnerability indicated that most did not believe their community to be at risk, though Bangladesh was. Remarks at Stage 2-Knowledge of Transmission were mostly vague but accurately identified sex, blood and needles as the main means of spread; however sex with sex workers was also mentioned in each group. Remarks at Stage 3-Prevention showed strong opposition to condoms for unmarried males and a preference for current means of forbidding sex outside of marriage. A few in each group recognized the importance of condoms for wayward youth. Stage 4-Planning discussions centered on raising awareness and fear, and a desire for government and media to take the lead. By 2007 participants articulated more realistic strategies that they themselves could, and had, implemented, but also raised barriers that authorities should help them overcome. The findings provide formative information on the constraints and opportunities of community groups as partners in HIV preventive interventions and strategies to help them move to a higher stage of readiness

Identifying venues where women meet sexual partners, particular partners who increase women's risk of acquiring HIV, could inform prevention efforts. We categorized venues where women enrolled in HPTN 064 reported meeting their last three sex partners as: (1) Formal, (2) Public, (3) Private, and (4) Virtual spaces. We used multinomial logistic regression to assess the association between these venues and women's individual characteristics and reports of their partners' HIV risk characteristics. The 2099 women reported meeting 3991 partners, 51 % at Public, 30 % Private, 17 % Formal and 3 % at Virtual venues. Women meeting partners at Formal venues reported more education and condom use than women meeting partners at other venues. Fewer partners met through Formal venues had “high” risk characteristics for HIV than through other venues and hence may pose less risk of HIV transmission. HIV prevention interventions can help women choose partners with fewer risk characteristics across all venue types. PMID:25863466
Full Text Available BACKGROUND: Uganda has one of the highest total fertility rates (TFR worldwide. We compared the effects of antiretroviral (ARV prophylaxis for the prevention of mother-to-child HIV transmission (PMTCT to that of existing family planning (FP use and estimated the burden of pediatric HIV disease due to unwanted fertility. METHODOLOGY/PRINCIPAL FINDINGS: Using the demographic software Spectrum, a baseline mathematical projection to estimate the current pediatric HIV burden in Uganda was compared to three hypothetical projections: 1 without ARV-PMTCT (to estimate the effect of ARV-PMTCT, 2 without contraception (effect of existing FP use, 3 without unwanted fertility (effect of unmet FP needs. Key input parameters included HIV prevalence, ARV-PMTCT uptake, MTCT probabilities, and TFR. We estimate that in 2007, an estimated 25,000 vertical infections and 17,000 pediatric AIDS deaths occurred (baseline projection. Existing ARV-PMTCT likely averted 8.1% of infections and 8.5% of deaths. FP use likely averted 19.7% of infections and 13.1% of deaths. Unwanted fertility accounted for 21.3% of infections and 13.4% of deaths. During 2008-2012, an estimated 131,000 vertical infections and 71,000 pediatric AIDS deaths will occur. The projected scale up of ARV-PMTCT (from 39%-57% may avert 18.1% of infections and 24.5% of deaths. Projected FP use may avert 21.6% of infections and 18.5% of deaths. Unwanted fertility will account for 24.5% of infections and 19.8% of deaths. CONCLUSIONS: Existing FP use contributes as much or more than ARV-PMTCT in mitigating pediatric HIV in Uganda. Expanding FP services can substantially contribute towards PMTCT.

The Global Plan towards the elimination of new HIV infections among children by 2015 and keeping their mothers alive (Global Plan) has ensured that more infants in high-HIV burden countries survive childhood HIV-free. Although equal numbers of boy and girl children have survived to age 10, a gender divergence starts to emerge as they enter adolescence. Up to 3 times as many young women aged 15-24 years in eastern and southern Africa are living with HIV compared with their male peers. Further, more adolescent girls and young women are sick and/or dying from AIDS-related or HIV-related complications during pregnancy and in the postpartum period, underscoring the importance of strengthening HIV treatment and prevention services for this group. Failure to prevent HIV in adolescent girls and young women and keep them alive will reverse the infant HIV prevention and survival gains made under the Global Plan. The promising global declines in HIV infection in young women need to be strengthened to realize the goals of an AIDS-free generation. The DREAMS initiative of the United States President's Emergency Plan for AIDS Relief (PEPFAR), which specifically addresses adolescent girls and young women at highest risk of HIV acquisition, brings new hope for meeting the prevention and care needs of this important and vulnerable population through political commitment, leadership, financial and human resource investments, advocacy efforts, and a focus on the highest priority settings. Importantly, to achieve the goal of keeping mothers alive, we have to place more emphasis on access to sexual and reproductive health services that (1) include HIV prevention and treatment services for adolescent girls and young women; (2) increase male/paternal responsibility in mother and infant health; and (3) ensure a supportive social environment that enables young women to grow up into young adults who are free to graduate from high school and plan their pregnancies, ultimately entering
Full Text Available Background: The current HIV epidemic in Thailand is primarily driven by new cases among men who have sex with men (MSM. HPTN052 study demonstrated 96% efficacy of immediate antiretroviral therapy (ART to reduce HIV transmission among serodiscordant heterosexual couples. As a result, universal HIV testing and immediate ART has emerged as a strategy to reduce HIV transmission in certain at-risk populations. The acceptability of this strategy, however, is unknown in MSM. Methods: From August 2011-March 2012, we conducted a cross-sectional study using self-administered questionnaires to assess attitudes towards universal HIV testing and immediate ART among MSM VCT clients in Bangkok. Participants were asked to complete the questionnaires prior to and after knowing their HIV status. The study was approved by the Institutional Review Board of the Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand. Results: Of 342 MSM, the median age (IQR was 26 (22–31 years, and 34.2% had bachelor's degree or higher. Previous HIV testing was reported by 69.9%, 35.2% of which had HIV testing annually. The most common reasons for previous HIV testing included perceived risk behaviors (63.6%, annual health checkup (26.4%, and partner's request (13.8%. Prior to receiving pre-test counseling, 74.4% expressed interest to get regular HIV testing. Health benefits from testing (59.6%, free testing (36.5%, and speedy service (35.7% were the most common persuasive reasons to come for regular HIV testing. Longevity (73.1% and prevention of HIV transmission to others (58.4% were reasons for interest in immediate ART (if tested positive program while costs (37.0% and life-long burden (36.7% were cited as main barriers. Among MSM who tested HIV-positive (n=45, 13.2%, the interest to participate in immediate ART program was very high both before and after knowing their HIV status (86.7% vs 93.3%, p=0.371. Among HIV-negative MSM, the interest to participate in regular
Full Text Available Two million two hundred thousand adults were newly HIV-infected in 2011, underscoring the urgent need for new, effective ways to prevent incident infections. Recently, the field of HIV prevention has gathered positive results from different strategies, among different populations, and with varying effect sizes, including the treatment of HIV-positive women and men in discordant couples, male circumcision of HIV-negative men in sub-Saharan Africa, a HIV vaccine evaluated in a community-based trial among HIV-negative men and women in Thailand, the use of vaginal gel formulation of TDF for HIV prevention in women in South Africa, pre-exposure prophylaxis (PrEP with tenofovir disoproxil fumarate (TDF or emtricitabine and TDF (TDF-FTC among HIV-1-serodiscordant heterosexual couples from Kenya and Uganda, and PrEP with TDF-FTC among heterosexual men and women in Africa. Of these interventions, PrEP is an attractive policy because it does not directly interferes with the sexual intercourse, providing people a choice on HIV prevention regardless of cultural, religious, or social harnesses.
In this paper the topic of consideration focuses on current methods and forms of implementation social crime prevention, as well as problems that often arise in practice during its implementation. This is one of the most important areas in crime prevention, which is also known as crime prevention through social development, and often includes legal activities of state and non-state actors aimed at preventing delinquency of children and minors through the weakening and, if possible, eliminatin...

Despite effective antiretroviral therapy (ART) and undetectable HIV RNA in the plasma, latent replication-competent HIV persists indefinitely in long-lived cells. Cessation of ART results in rebound of HIV from these persistent reservoirs. While this was thought to be an insurmountable obstacle to viral eradication, recent cases suggest otherwise. To date one patient has been "cured" of HIV and several others have been able to interrupt ART without viral rebound for prolonged periods. These events have sparked renewed interest in developing strategies that will allow eradication of HIV in infected individuals. We review the current knowledge of HIV latency and the viral reservoir, describe the potential utility of emerging cancer therapeutics in HIV cure research with an emphasis on pathways implicated in reservoir persistence, and outline opportunities and challenges in the context of the current clinical trial and regulatory environment.

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

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

Full Text Available Until now, decisions about how to allocate ART have largely been based on maximising the therapeutic benefit of ART for patients. Since the results of the HPTN 052 study showed efficacy of antiretroviral therapy (ART in preventing HIV transmission, there has been increased interest in the benefits of ART not only as treatment, but also in prevention. Resources for expanding ART in the short term may be limited, so the question is how to generate the most prevention benefit from realistic potential increases in the availability of ART. Although not a formal systematic review, here we review different ways in which access to ART could be expanded by prioritising access to particular groups based on clinical or behavioural factors. For each group we consider (i the clinical and epidemiological benefits, (ii the potential feasibility, acceptability, and equity, and (iii the affordability and cost-effectiveness of prioritising ART access for that group. In re-evaluating the allocation of ART in light of the new data about ART preventing transmission, the goal should be to create policies that maximise epidemiological and clinical benefit while still being feasible, affordable, acceptable, and equitable.
Full Text Available To project the HIV/AIDS epidemics among men who have sex with men (MSM under different combinations of HIV testing and linkage to care (TLC interventions including antiretroviral therapy (ART in Beijing, China.Mathematical modeling.Using a mathematical model to fit prevalence estimates from 2000-2010, we projected trends in HIV prevalence and incidence during 2011-2020 under five scenarios: (S1 current intervention levels by averaging 2000-2010 coverage; (S2 increased ART coverage with current TLC; (S3 increased TLC/ART coverage; (S4 increased condom use; and (S5 increased TLC/ART plus increased condom use.The basic reproduction number based upon the current level of interventions is significantly higher than 1 (R0 = 2.09; 95% confidence interval (CI, 1.83-2.35, suggesting that the HIV epidemic will continue to increase to 2020. Compared to the 2010 prevalence of 7.8%, the projected HIV prevalence in 2020 for the five prevention scenarios will be: (S1 Current coverage: 21.4% (95% CI, 9.9-31.7%; (S2 Increased ART: 19.9% (95% CI, 9.9-28.4%; (S3 Increased TLC/ART: 14.5% (95% CI, 7.0-23.8%; (S4 Increased condom use: 13.0% (95% CI, 9.8-28.4%; and (S5 Increased TLC/ART and condom use: 8.7% (95% CI, 5.4-11.5%. HIV epidemic will continue to rise (R0 > 1 for S1-S4 even with hyperbolic coverage in the sensitivity analysis, and is expected to decline (R0 = 0.93 for S5.Our transmission model suggests that Beijing MSM will have a rapidly rising HIV epidemic. Even enhanced levels of TLC/ART will not interrupt epidemic expansion, despite optimistic assumptions for coverage. Promoting condom use is a crucial component of combination interventions.
Full Text Available BACKGROUND: For the first time in the history of HIV, new bio-medical interventions have been shown to be effective in preventing HIV transmission. For these new HIV prevention technologies (NPTs to have an impact on the epidemic, they must be widely used. This study uses a discrete choice experiment (DCE to: understand the relative strength of women's preferences for product characteristics, understand the implications for substitution away from male condoms, and inform realistic modelling of their potential impact and cost-effectiveness. METHODS: A DCE was conducted among 1017 women in urban South Africa. Women were presented with choices between potential women's NPTs (microbicides, diaphragm, female condom and 'what I did last time' (use or not use a condom with different HIV and pregnancy prevention effectiveness' and prices. Choice probabilities are estimated using the nested logit model and used to predict uptake. RESULTS: In this high HIV prevalence setting, HIV prevention effectiveness is the main driver of uptake followed by pregnancy prevention effectiveness. For example a microbicide with poor effectiveness would have niche appeal at just 11% predicted uptake, while a highly effective microbicide (95% effective against HIV and pregnancy would have far wider appeal (56% predicted uptake. Though women who reported not using condoms were more likely to choose the NPTs, at current very high rates of male condom use in South Africa (60%, about half of microbicide uptake is projected to be among those currently not using condoms. CONCLUSIONS: Women are very interested in NPTs, especially if highly effective in preventing HIV and pregnancy. Women in greatest need were also most likely to switch to the new products. Where products are not yet available for distribution, proxy data, such as that generated by DCEs, can bring realism to overly optimistic uptake scenarios found in many current impact models.

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

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

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.

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.

Full Text Available Pre-exposure prophylaxis” (PrEP has been recently developed as a prevention strategy which involves the administration of drugs to non-infected individuals who present high exposure or susceptibility to HIV. Although this use is not approved in our country, several guidelines recommend PrEP as a prevention option in adult MSM, heterosexual men and women, and users of parenteral drugs at risk of acquiring the infection. This article presents the characteristics that an ideal agent to be used as PrEP should meet, recent efficacy published data and barriers for the implementation of this new strategy. On the other hand, the role of hospital pharmacists will be discussed.
Full Text Available Abstract Background Harm reduction is a health-centred approach that seeks to reduce the health and social harms associated with high-risk behaviors, such as illicit drug use. The objective of this study is to determine the association between the beliefs of a group of adult, male prisoners in Iran about the transmission of HIV and their high-risk practices while in prison. Methods A cross-sectional study was conducted in 2004. The study population was a random selection of 100 men incarcerated at Rajaei-Shahr prison. The data were collected through a self-administered questionnaire. Focus group discussions were held at the prison to guide the design of the questionnaire. The relationship between components of the Health Belief Model (HBM and prisoners' risky HIV-related behaviors was examined. Results Calculating Pearson's correlation coefficient, a significant, positive association was found between the benefit component of the HBM and prisoners not engaging in HIV high-risk behaviors. Conclusion Educational harm reduction initiatives that promote the effectiveness of strategies designed to reduce the risk of HIV transmission may decrease prisoners' high-risk behaviors. This finding provides initial support for the Iran prison system's current offering of HIV/AIDS harm reduction programming and suggests the need to offer increased education about the effectiveness of HIV prevention practices.

Full Text Available Abstract Background AIDS continues to spread at an estimated 2.6 new million infections per year, making the prevention of HIV transmission a critical public health issue. The dramatic growth in global resources for AIDS has produced a steady scale-up in treatment and care that has not been equally matched by preventive services. This paper is a detailed analysis of how countries are choosing to spend these more limited prevention funds. Methods We analyzed prevention spending in 69 low- and middle-income countries with a variety of epidemic types, using data from national domestic spending reports. Spending information was from public and international sources and was analyzed based on the National AIDS Spending Assessment (NASA methods and classifications. Results Overall, prevention received 21% of HIV resources compared to 53% of funding allocated to treatment and care. Prevention relies primarily on international donors, who accounted for 65% of all prevention resources and 93% of funding in low-income countries. For the subset of 53 countries that provided detailed spending information, we found that 60% of prevention resources were spent in five areas: communication for social and behavioral change (16%, voluntary counselling and testing (14%, prevention of mother-to-child transmission (13%, blood safety (10% and condom programs (7%. Only 7% of funding was spent on most-at-risk populations and less than 1% on male circumcision. Spending patterns did not consistently reflect current evidence and the HIV specific transmission context of each country. Conclusions Despite recognition of its importance, countries are not allocating resources in ways that are likely to achieve the greatest impact on prevention across all epidemic types. Within prevention spending itself, a greater share of resources need to be matched with interventions that approximate the specific needs and drivers of each country's epidemic.

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.

In 2008, between 129,000 and 194,000 of the 430,000 pediatric HIV infections worldwide were attributable to breastfeeding. Yet in many settings, the health, economic, and social consequences of not breastfeeding would have dire consequences for many more children. In the first part of this review we provide an overview of current knowledge about infant feeding in the context of HIV. Namely, we describe the benefits and risks of breastmilk, the evolution of recommended infant feeding modalities in high-income and low-income countries in the last two decades, and contextualize the recently revised guidelines for infant feeding in the context of HIV current knowledge. In the second section, we suggest areas for future research on the postnatal prevention of mother-to-child transmission of HIV (PMTCT) in developing and industrialized countries. We suggest two shifts in perspective. The first is to evaluate PMTCT interventions more holistically, to include the psychosocial and economic consequences as well as the biomedical ones. The second shift in perspective should be one that contextualizes postnatal PMTCT efforts in the cascade of maternal health services. We conclude by discussing basic, clinical, behavioral, and programmatic research questions pertaining to a number of PMTCT efforts, including extended postnatal ARV prophylaxis, exclusive breastfeeding promotion, counseling, breast milk pasteurization, breast milk banking, novel techniques for making breast milk safer, and optimal breastfeeding practices. We believe the research efforts outlined here will maximize the number of healthy, thriving, HIV-free children around the world. PMID:22332055

This qualitative study aims to gain in-depth information about the attitudes of HIV-serodiscordant couples towards two new methods of HIV prevention; Pre-Exposure Prophylaxis and Treatment as Prevention, both of which have been recently recommended by the World Health Organisation. Semi-structured interviews were conducted with 38 individuals in a serodiscordant relationship in Western Kenya. Topic guides were used to elicit information on perceived benefits, concerns, and preferences towards Treatment as Prevention and Pre-Exposure Prophylaxis. Data evaluation and thematic generation were developed using framework analysis. Results suggest that the majority of participants, irrespective of gender and HIV status, found Treatment as Prevention the more acceptable strategy. Key factors influencing this decision were HIV-negative participants' limited motivation to take prophylactic antiretrovirals and the likely health improvements Treatment as Prevention offers HIV-positive partners. However, issues were raised concerning the likelihood of low concurrent condom use and poor medication adherence when using these preventative approaches. It was concluded that the adoption of Treatment as Prevention as a method of HIV control in Kenya is likely to be more readily accepted by serodiscordant couples than Pre-exposure Prophylaxis. However, future implementation of either strategy would require measures to address the possibility of risk compensation and poor adherence.

Full Text Available Context: Around 2.5 million people become infected with HIV each year and its impact on human life and public health can only be tackled and reversed only by sound prevention strategies. Aim: This paper aims to provide the reader about different types of prevention strategies that are effective and practiced in various countries with special emphasis on evidence for success. It also highlights the importance of to the evidence based medicine& strategies. It describes about the importance of combination prevention, which encompasses complementary behavioral, biomedical and structural prevention strategies. Methods & Materials: Searches for peer reviewed journal articles was conducted using the search engines to gather the information from databases of medicine, health sciences and social sciences. Information for each strategy is organized & presented systematically with detailed discussion. Results: For a successful reduction in HIV transmission, there is a great need for combined effects of radical & sustainable behavioral changes among individuals who are potentially at risk. Second, combination prevention is essential for HIV prevention is neither simple nor simplistic. Reductions in HIV transmission need widespread and sustained efforts. A mix of communication channels are essential to disseminate messages to motivate people to engage in various methods of risk reduction. Conclusions: The effect of behavioral strategies could be increased by aiming for many goals that are achieved by use of multilevel approaches with populations both uninfected and infected with HIV. Combination prevention programs operate on different levels to address the specific, but diverse needs of the populations at risk of HIV infection.

Evidence that treating people with HIV early in infection prevents transmission to sexual partners has reframed HIV prevention paradigms. The resulting emphasis on HIV testing as part of prevention strategies has rekindled the debate as to whether laws that criminalise HIV transmission are counterproductive to the human rights-based public health response. It also raises normative questions about what constitutes 'safe(r) sex' if a person with HIV has undetectable viral load, which has significant implications for sexual practice and health promotion. This paper discusses a recent high-profile Australian case where HIV transmission or exposure has been prosecuted, and considers how the interpretation of law in these instances impacts on HIV prevention paradigms. In addition, we consider the implications of an evolving medical understanding of HIV transmission, and particularly the ability to determine infectiousness through viral load tests, for laws that relate to HIV exposure (as distinct from transmission) offences. We conclude that defensible laws must relate to appreciable risk. Given the evidence that the transmissibility of HIV is reduced to negligible level where viral load is suppressed, this needs to be recognised in the framing, implementation and enforcement of the law. In addition, normative concepts of 'safe(r) sex' need to be expanded to include sex that is 'protected' by means of the positive person being virally suppressed. In jurisdictions where use of a condom has previously mitigated the duty of the person with HIV to disclose to a partner, this might logically also apply to sex that is 'protected' by undetectable viral load.

The objectives of this study were to describe knowledge, attitudes, and self-awareness, and to identify predictable factors affecting HIV/AIDS prevention among Thai university students. A cross sectional survey was conducted among 844 first-year university students using a validated, self-administered questionnaire as a research instrument. The questionnaire included items assessing knowledge, attitudes, self-awareness, and HIV/AIDS preventive behaviors. It was found that 22.4% of the subjects received various sexually provocative media. The university student's knowledge, attitudes, self-awareness, and preventive behaviors toward HIV/AIDS were at a high level. The results from the multiple regression analysis identified self-awareness, faculty, sex, sexual-risk score, income-per-month, GPA, and knowledge as significant independent predictors of HIV/AIDS preventive behaviors. These factors contributed to 36.9% of the explanation of HIV preventive behaviors, and the strongest predictor was found to be self-awareness. Scientific information, and useful and productive life skills are needed to educate the university students regarding the health consequences of HIV/AIDS. An integrated approach is strongly suggested for creating knowledge, attitudes, and awareness to control the spread of HIV/AIDS among young people.

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

Abstract The government of Botswana has been spending a lot of money in the prevention, treatment, care and support for HIV/AIDS patient for decades. This paper uses data from the third Botswana AIDS Impact Survey (BAIS III) to explore high-risk behaviors of adults and how they affect government efforts to stop the spread of HIV/AIDS. The objective of this paper is to fill in the gap on the assessment of high-risk behaviors associated with HIV/AIDS and their implications on HIV/AIDS prevention efforts. A nationally representative sample of 10,159 men and women aged 20–64 years who had successfully completed the BAIS III individual questionnaire were used in the study. Both descriptive and binary logistic regression analyses were used for analysis. Crude odds ratios were obtained from gross effects model while adjusted odds ratios (AOR) were obtained from the net effects model. Statistically significant association was observed between multiple current partners and alcohol consumption (AOR = 1.5), drug abuse (AOR = 1.7), transactional sex (AOR = 2.6) and intergenerational sex (AOR = 1.07). Furthermore, statistically significant association was seen for inconsistent condom use and having tested for HIV (AOR = 1.5). These results show a worrying tendency that despite government's efforts to stop the spread of HIV/AIDS, adults in Botswana continue to indulge in high-risk behaviors. Therefore, any programs and policies on HIV/AIDS should first target these high-risk behaviors. PMID:25293869

Full Text Available Bangladesh is believed to be a low HIV prevalent country although the potentiality of spreading HIV remains high because of several contributing factors. There is many sex –workers active with highest sexual contacts and partner exchange but low condom use by both sex workers and their clients expedite the prevalence significantly. There is a sizable population of men who have sex with men and hijra –those who usually do not use condom and consequently high rates of sexually transmitted infections (STIs prevailed in them. Stigma and discrimination against most at risk populations (MARPs is the biggest hurdle to bring them under prevention services against HIV/AIDS in Bangladesh. Therefore Bangladesh is vulnerable to HIV/STI. Condom outlet is a gypsy platform in where most at risk peoples are getting free access to condom at their will. The paper attempts to identify the underlying role of community condom outlet for the prevention of HIV/STI in Bangladesh. Condom outlets are working as an inseparable volunteer under outreach service of HIV/STI prevention project through diversified role as monitor of peer educators, knowledge store of HIV/STI, conflict solver, shelter of peer, outreach worker as well as project staff to fight against HIV/AIDS in Bangladesh. The theoretical approach and literature review of this study provides an understanding of community condom outlet. The researchers try to answer the questions of who the community condom outlets are, what their lifestyle in preventing HIV / STI and how condom outlet are working with community for preventing HIV and STI.
Full Text Available Introduction: As a group, transwomen in Peru have the highest prevalence of HIV (>20% in the country, but they have little access to HIV prevention, testing and care services. Until recently, Peru's national HIV programme did not recognize transwomen and had remained essentially static for decades. This changed in December 2014, when the Ministry of Health expressed its commitment to improve programming for transwomen and to involve transwomen organizations by prioritizing the development of a “Targeted Strategy Plan of STIs/HIV/AIDS Prevention and Comprehensive Care for Transwomen.” Discussion: A policy dialogue between key stakeholders – Peru's Ministry of Health, academic scientists, civil society, transgender leaders and international agencies – created the conditions for a change in Peru's national HIV policy for transwomen. Supported by the effective engagement of all sectors, the Ministry of Health launched a plan to provide comprehensive HIV prevention and care for transwomen. The five-year plan includes new national guidelines for HIV prevention, care and support, and country-level investments in infrastructure and equipment. In addition to new biomedical strategies, the plan also incorporates several strategies to address structural factors that contribute to the vulnerability of transwomen. We identified three key factors that created the right conditions for this change in Peru's HIV policy. These factors include (1 the availability of solid evidence, based on scientific research; (2 ongoing efforts within the transwomen community to become better advocates of their own rights; and (3 a dialogue involving honest discussions between stakeholders about possibilities of changing the nation's HIV policy. Conclusions: The creation of Peru's national plan for HIV prevention and care for transwomen shows that long-term processes, focused on human rights for transwomen in Peru, can lead to organizational and public-policy change.

To conduct composite economic analysis of HIV prevention interventions to inform efficient utilization of resources in India. We obtained output and economic cost data for the 2005-2006 fiscal year from a representative sample of 128 public-funded HIV prevention programmes of 14 types in Andhra Pradesh state of India. Using data from various sources, we developed a model to estimate the number of HIV infections averted. We estimated the additional HIV infections that could be averted if each intervention reached optimal coverage and the associated cost. In a year, 9688 HIV infections were averted by public-funded HIV prevention interventions in Andhra Pradesh. Scaling-up interventions to the optimal level would require US$38.8 million annually, 2.8 times the US$13.8 million economic cost in 2005-2006. This could increase the number of HIV infections averted by 2.4-fold, if with higher resources there were many-fold increases in the proportional allocation for programmes for migrant labourers, men who have sex with men and voluntary counselling and testing, and reduction of the high proportion for mass media campaigns to one-third of the 2005-2006 proportion of resource utilization. If the proportions of resource allocation for interventions remained similar to 2005-2006, the higher resources would avert 54% of the additional avertable HIV infections. The recent four-fold increase in public funding for HIV/AIDS control in India should be adequate to scale-up HIV prevention interventions to an optimal level in Andhra Pradesh, but the prevention would be suboptimal if additional investments were not preferentially directed to some particular interventions.

The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit. We assembled a panel of experts appointed by the Secretariat of the National AIDS Plan (SPNS) and the other participating Scientific Societies, which included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists. Four panel members acted as coordinators. Scientific information was reviewed in publications and conference reports up to November 2012. In keeping with the criteria of the Infectious Diseases Society of America, 2levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C), and the level of empirical evidence (I, II, III). This approach has already been used in previous documents from SPNS. The aim of this paper was to review current scientific knowledge, and, accordingly, develop a set of recommendations regarding antiretroviral therapy (ART), regarding the health of the mother, and from the perspective of minimizing mother-to-child transmission (MTCT), also taking into account the rest of the health care of pregnant women with HIV infection. We also discuss and evaluate other strategies to reduce the MTCT (elective Cesarean, child's treatment…), and different aspects of the topic (ARV regimens, their toxicity, monitoring during pregnancy and postpartum, etc.).

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.

The epidemic of HIV infection and HIV/AIDS in Minnesota reflects national trends in transmission and progression to disease. Analysis of Minnesota's data also highlights populations that are at much greater risk for HIV infection and progression to AIDS. Although men who have sex with men continue to comprise the majority of people in Minnesota with HIV, other subpopulations--women, people of color, and foreign-born residents--are seeing a rise in their infection rates as well. Members of these groups tend to be diagnosed later and, thus, are at greater risk for their infection to progress to AIDS. This article discusses some of the nuances of the most recent epidemiologic data on HIV/AIDS in Minnesota and makes the case for continued aggressive strategies for outreach, education, and adequate access to health care services among at-risk populations.

Evidence-based guidance regarding use of nearly all pharmaceuticals by pregnant and lactating women is limited. Models for performing research may assist in filling these knowledge gaps. Internationally, reproductive age women are at high risk of human immunodeficiency virus (HIV) acquisition. Susceptibility to HIV infection may be increased during pregnancy, and risk of maternal-child transmission is increased with incident HIV infection during pregnancy and lactation. A multidisciplinary meeting of experts was convened at the United States National Institutes of Health to consider paradigms for drug research in pregnancy and lactation applicable to HIV prevention. This report summarizes the meeting proceedings and describes a framework for research on candidate HIV prevention agent use during pregnancy and lactation that may also have broader applications to other pharmaceutical products.

One quarter of HIV cases occur in women ages 15-44 years. We investigated preferential HIV prevention message mediums among college women (18-21 years of age) and their association with parent and partner communication. A nonexperimental cross-sectional survey assessed factors associated with parent and partner communication among 626 single female students who were sexually active in the previous 6 months and attending a 4-year public university in Florida. Women who perceived themselves to be at elevated risk of acquiring HIV were more likely to communicate with their parents (p communicate about sexual risk behavior with their parents when mothers were younger and when less influenced by their peers. Reading items on the Internet about intravenous drug use and HIV were independently associated with higher parent and partner communication, respectively. Findings can guide future HIV prevention communication interventions.

Dendrimers containing from 9 to 18 tryptophan residues at the peryphery have been efficiently synthesized and tested against HIV replication. These compounds inhibit an early step of the replicative cycle of HIV, presumably virus entry into its target cell. Our data suggest that HIV inhibition can be achieved by the preferred interaction of the compounds herein described with glycoproteins gp120 and gp41 of the HIV envelope preventing interaction between HIV and the (co)receptors present on the host cells. The results obtained so far indicate that 9 tryptophan residues on the periphery are sufficient for efficient gp120/gp41 binding and anti-HIV activity.
Full Text Available Abstract Background HIV prevention continues to be problematic in the UK, as it does globally. The UK Department of Health has a strategic direction with greater focus on prevention as part of its World Class Commissioning Programme. There is a need for targeted evidence-based prevention initiatives. This is an exploratory study to develop an evidence mapping tool in the form of a matrix: this will be used to identify important gaps in contemporary HIV prevention evidence relevant to the UK. It has the potential to aid prioritisation in future research. Methods Categories for prevention and risk groups were developed for HIV prevention in consultation with external experts. These were used as axes on a matrix tool to map evidence. Systematic searches for publications on HIV prevention were undertaken using electronic databases for primary and secondary research undertaken mainly in UK, USA, Canada, Australia and New Zealand, 2006-9. Each publication was screened for inclusion then coded. The risk groups and prevention areas in each paper were counted: several publications addressed multiple risk groups. The counts were exported to the matrix and clearly illustrate the concentrations and gaps of literature in HIV prevention. Results 716 systematic reviews, randomised control trials and other primary research met the inclusion criteria for HIV prevention. The matrix identified several under researched areas in HIV prevention. Conclusions This is the first categorisation system for HIV prevention and the matrix is a novel tool for evidence mapping. Some important yet under-researched areas have been identified in HIV prevention evidence: identifying the undiagnosed population; international adaptation; education; intervention combinations; transgender; sex-workers; heterosexuals and older age groups. Other research recommendations: develop the classification system further and investigate transferability of the matrix to other prevention areas

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.

Rapid HIV tests have been widely adopted globally as an important component of HIV prevention and control programs. The INSTI™ HIV-1/HIV-2 antibody test is a second-generation HIV antibody test, available in most countries for use from whole blood, serum, and plasma. Available data on kit characteristics and current performance data on the INSTI™ HIV-1/HIV-2 antibody test are presented together with six other rapid point-of-care tests (RPOCTs) for HIV antibody. Few published data are available providing direct comparisons of INSTI™ with other RPOCTs for HIV antibody and standard laboratory-based HIV-1/HIV-2 antibody assays. Existing data showed that INSTI™ has comparable performance to other RPOCTs but detected seroconversion later than standard laboratory-based assays. The good performance of INSTI HIV-1/HIV-2 antibody test, its ease of use, the rapid availability of results (resource-limited settings.

Setting: One hundred and forty non-governmental organisations implementing human immunodeficiency virus (HIV) prevention programmes among clients, including people who inject drugs, prisoners, female sex workers, men who have sex with men and street children in Ukraine, 2010–2011. Objective: Among enrolled clients, to assess factors associated with HIV testing, HIV retesting within a year of initial testing and HIV seroconversion. Design: Retrospective cohort study involving record reviews. Results: Of 192 487 clients, 42 109 (22%) underwent an initial HIV test (22% were positive). Among HIV-negative clients at baseline, 10 858 (27%) were retested within a year: 317 (3%) of these were HIV-positive. HIV testing and retesting rates were lower among prisoners (0.3%) and others (street children and partners of those in risk groups, 6%), and those who did not receive counselling or services such as condom and needle distribution. Individuals who were not counselled were more likely to seroconvert. Conclusions: In this large cohort of high-risk groups from Eastern Europe, HIV testing was low and HIV sero-conversion was high. This is of public health concern, bringing into question the overall quality of counselling and how well it is tailored to the specific needs of various risk groups. Qualitative studies to understand the reasons for non-testing are urgently required for designing client-specific interventions. PMID:26399206
Full Text Available Background Human immunodeficiency virus (HIV infection is increasing worldwide. One route of HIV transmission is from mother to child, during pregnancy, delivery or breastfeeding. Prevention of mother-to-child transmission may be an effective strategy to reduce the cases of new HIV infections. Objectives To investigate the incidence of HIV infection in infants born to mothers with HIV and who received prophylactic therapy at birth, as well as to note the outcomes of HIV-infected children in this program. Methods This retrospective study was carried out over a 9-year period, from January 2003 to December 2011. The participants were HIV-exposed infants who attended the HIV clinic, at the Department of Child Health, Cipto Mangunkusumo Hospital Jakarta. Infants were treated according to the prevention of mother-to-child transmission (PMTCT protocol at CMH. Parents’ and infants’ data was recorded. The end point of this study was recording of HIV-infection status in the infants. Results There were 238 infants included in this study. HIV infection was confirmed in 6 (2.5% infants, while 170 (72.4% subjects were uninfected, and 62 (26.1% subjects were lost to foloow-up. No subjects who underwent complete PMTCT management were infected. Most subjects were male, full-term, and delivered by caesarean section in our hospital. The most frequently observed parental risk factor was intravenous drug use. Maternal antiretroviral theraphy (ART was given during pregnancy in most cases. Morbidities in all subjects were low. Conclusion The PMTCT program at CMH was effective for reducing the number of HIV-infected infants from mothers with HIV

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

Full Text Available Abstract Background HIV testing rates have exceeded 90% among the pregnant women at Mbale Regional Referral Hospital in Mbale District, eastern Uganda, since the introduction of routine antenatal counselling and testing for HIV in June 2006. However, no documented information was available about opinions of pregnant women in eastern Uganda about this HIV testing approach. We therefore conducted a study to assess attitudes of antenatal attendees towards routine HIV counselling and testing at Mbale Hospital. We also assessed their knowledge about mother to child transmission of HIV and infant feeding options for HIV-infected mothers. Methods The study was a cross-sectional survey of 388 women, who were attending the antenatal clinic for the first time with their current pregnancy at Mbale Regional Referral Hospital from August to October 2009. Data were collected using a pre-tested questionnaire and analysed using descriptive statistics and logistic regression. Permission to conduct the study was obtained from the Makerere University College of Health Sciences, the Uganda National Council of Science and Technology, and Mbale Hospital. Results The majority of the antenatal attendees (98.5%, 382/388 had positive attitudes towards routine HIV counselling and testing, and many of them (more than 60% had correct knowledge of how mother to child transmission of HIV could occur during pregnancy, labour and through breastfeeding, and ways of preventing it. After adjusting for independent variables, having completed secondary school (odds ratio: 2.5, 95% confidence interval: 1.3-4.9, having three or more pregnancies (OR: 2.5, 95% CI: 1.4-4.5 and belonging to a non-Bagisu ethnic group (OR: 1.7, 95% CI: 1.0-2.7 were associated with more knowledge of exclusive breastfeeding as one of the measures for prevention of mother to child transmission of HIV. Out of 388 antenatal attendees, 386 (99.5% tested for HIV and 382 (98.5% received same-day HIV test results

To provide evidence for resource allocation and cooperation between domestic and international HIV/AIDS programs in China by analyzing the needs and current levels of resource input in provinces. National and provincial international cooperation program investment and allocation data from 2000 to 2006 were collected. Several factors in each province were analyzed through multiple regression analysis in order to determine whether they had a statistical correlation to the distribution of international HIV/AIDS program resources in China, including: the Gross Domestic Product (GDP), the number of accumulated people living with HIV/AIDS, and the number of accumulated people living with AIDS. Then the Z values were calculated at each provincial level and compared with related international investment. The resource allocation in different program areas were compared with the level of resource input by international and central government HIV/AIDS prevention and control programs through Chi-square test. The international cooperation program investment at local level from 2000 to 2006 were 4893, 24 669, 50 567, 52 950, 112 143, 363 396 and 247 045 thousand RMB respectively, and at national level were 3007, 19 726, 29 035, 37 530, 77 500, 105 786 and 77 035 thousand RMB respectively. There was a statistical correlation between international HIV/AIDS program resource input and the accumulated number of people living with AIDS (R is 0.56 and 0.69 accordingly, and P invest in each province according to its practical needs (R = 0.066, P = 0.725). The international cooperation program investments and needs in different province could not meet completely. The ranks of Z value in Guangdong, Shandong and Jiangsu were 3, 5 and 6, but the ranks of international cooperation program in those provinces were 18, 13 and 28 respectively.

The global HIV pandemic began to expand rapidly in southern Africa a decade later than was noted in central Africa, Europe, the Caribbean, and North America. Multiple factors played a role in this rapid expansion which led Southern Africa to become the most heavily afflicted region for HIV/AIDS globally. In this issue of Current HIV/AIDS Reports, investigators with active research interests in the region have reviewed key elements of the causes of and responses to the epidemic. Putative cause...

infections. Among uncircumcised adult HIV positive males, HR-HPV prevalence ranged from 55.3% -76.6% compared to 38.6% -47.6% in HIV negative males. Incident and multiple HR-HPV infections were frequent in HIV positive males. Being uncircumcised was the main risk factor for both prevalent and incident HPV infection. Conclusion Infections with HR-HPV genotypes were very common particularly among HIV positive individuals and young women irrespective of HIV status. Given the high prevalence of HIV infection, HPV-associated conditions represent a major public health burden in Uganda. However, although the most common HPV genotypes in ICC cases in Uganda were those targeted by current preventive vaccines, there were a large number of individuals infected with other HR-HPV genotypes. Technology allowing, these other HR-HPV types should be considered in the development of the next generation of vaccines.

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

Evidence-based interventions have been developed and used to prevent HIV infections among black men who have sex with men (MSM) in Canada and the United States; however, the degree to which interventions address racism and other interlocking oppressions that influence HIV vulnerability is not well known. We utilize integrative antiracism to guide a review of HIV prevention intervention studies with black MSM and to determine how racism and religious oppression are addressed in the current intervention evidence base. We searched CINAHL, PsychInfo, MEDLINE and the CDC compendium of evidence-based HIV prevention interventions and identified seventeen interventions. Three interventions targeted black MSM, yet only one intervention addressed racism, religious oppression, cultural assets and religious assets. Most interventions' samples included low numbers of black MSM. More research is needed on interventions that address racism and religious oppression on HIV vulnerability among black MSM. Future research should focus on explicating mechanisms by which multiple oppressions impact HIV vulnerability. We recommend the development and integration of social justice tools for nursing practice that aid in addressing the impacts of racism and other oppressions on HIV vulnerability of black MSM. © 2014 John Wiley & Sons Ltd.

This article reviews the effectiveness of HIV sexual risk prevention programs among adult prison inmates. A database search was performed to identify studies that used HIV sexual risk prevention programs with incarcerated adults. Of the 234 articles identified, 9 met the inclusion criteria. In addition, 5 articles were found containing supporting information for the 9 studies reviewed, increasing the number of articles reviewed to 14. All studies reported a significant increase in knowledge or a decrease in high-risk behaviors among the inmates at the conclusion of the interventions. Common limitations included a lack of a theoretical framework used in developing the interventions, a lack of process evaluations to measure program fidelity, and a lack of validity and reliability reporting for the study surveys. However, programs and interventions targeting HIV and sexual risk reduction appear to improve the knowledge of HIV prevention and reduce risk in the adult prison inmate population.

Community stakeholder engagement is foundational to fair and ethically conducted biomedical HIV prevention trials. Concerns regarding the ethical engagement of community stakeholders in HIV vaccine trials and early terminations of several international pre-exposure prophylaxis trials have fueled the development of international guidelines, such as UNAIDS' good participatory practice (GPP). GPP aims to ensure that stakeholders are effectively involved in all phases of biomedical HIV prevention trials. We provide an overview of the six guiding principles in the GPP and critically examine them in relation to existing social and behavioral science research. In particular, we highlight the challenges involved in operationalizing these principles on the ground in various global contexts, with a focus on low-income country settings. Increasing integration of social science in biomedical HIV prevention trials will provide evidence to advance a science of community stakeholder engagement to support ethical and effective practices informed by local realities and sociocultural differences.

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

Social marketing techniques have been tested and proven useful within the health sector worldwide. In Fiji, social marketing was introduced in the early 1990s, and more rapidly during the last decade to improve national response to an increasing incidence of sexually transmitted infections (STIs) such as human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). Given the limited amount of research in the area of program evaluation in Pacific Island Countries and Territories (PICTs), this study systematically analyzes five Fijian HIV/AIDS prevention programs through Andreasen's benchmark criteria, in order to identify gaps in program design that ultimately impact program effectiveness. Assessment results unveil some interesting trends regarding the focus and applications of past Fijian HIV/AIDS prevention programs in the past decade. This article discusses these findings and other valuable lessons for future HIV/AIDS prevention strategies in Fiji and elsewhere.
Full Text Available Abstract Background Lower-than-expected incidence of HIV undermines sample size calculations and compromises the power of a HIV prevention trial. We evaluated the effectiveness of interim monitoring of HIV infection rates and on-going modification of recruitment strategies to enroll women at higher risk of HIV in the Cellulose Sulfate Phase III study in Nigeria. Methods We analyzed prevalence and incidence of HIV and other sexually transmitted infections, demographic and sexual behavior characteristics aggregated over the treatment groups on a quarterly basis. The site investigators were advised on their recruitment strategies based on the findings of the interim analyses. Results A total of 3619 women were screened and 1644 enrolled at the Ikeja and Apapa clinics in Lagos, and at the Central and Peripheral clinics in Port Harcourt. Twelve months after study initiation, the overall incidence of HIV was less than one-third of the pre-study assumption, with rates of HIV that varied substantially between clinics. Due to the low prevalence and incidence rates of HIV, it was decided to close the Ikeja clinic in Lagos and to find new catchment areas in Port Harcourt. This strategy was associated with an almost two-fold increase in observed HIV incidence during the second year of the study. Conclusion Given the difficulties in estimating HIV incidence, a close monitoring of HIV prevalence and incidence rates during a trial is warranted. The on-going modification of recruitment strategies based on the regular analysis of HIV rates appeared to be an efficient method for targeting populations at greatest risk of HIV infection and increasing study power in the Nigeria trial. Trial Registration The trial was registered with the ClinicalTrials.gov registry under #NCT00120770 http://clinicaltrials.gov/ct2/show/NCT00120770

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.
Full Text Available BACKGROUND: This paper presents findings from a qualitative investigation of ethical and participatory issues related to the conduct of biomedical HIV prevention trials among marginalized populations in Thailand. This research was deemed important to conduct, as several large-scale biomedical HIV prevention trials among marginalized populations had closed prematurely in other countries, and a better understanding of how to prevent similar trial closures from occurring in the future was desired. METHODS: In-depth key informant interviews were held in Bangkok and Chiang Mai, Thailand. Interviews were audio recorded, transcribed, translated and thematically analyzed. The Good Participatory Practice Guidelines for Biomedical HIV Prevention Trials (GPP guided this work. RESULTS: Fourteen interviews were conducted: 10 with policymakers, academic and community-based researchers and trial staff and four with representatives of non-governmental organizations (NGOs. Suggested ways to improve ethical and participatory practice centered on standards of HIV prevention, informed consent, communication and human rights. In particular, the need to overcome language and literacy differences was identified. Key informants felt communication was the basis of ethical understanding and trust within biomedical HIV prevention trial contexts, and thus fundamental to trial participants' ability to exercise free will. DISCUSSION: Biomedical HIV prevention trials present opportunities for inclusive and productive ethical and participatory practice. Key informants suggested that efforts to improve practice could result in better relationships between research stakeholders and research investigative teams and by extension, better, more ethical participatory trials. This research took place in Thailand and its findings apply primarily to Thailand. However, given the universality of many ethical considerations, the results of this study can inform the improvement of ethical

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

If the transmission of human immunodeficiency virus (HIV) is to be prevented, the environment in which people live should predispose them to engage in and sustain safe behaviors. Too often in public health, the range of organizations that make up that environment are overlooked, and prevention strategies are limited to familiar medical and public health institutions. Improvement in public health does not occur in isolation, apart from the other institutions of society--and so it is with the HIV-AIDS epidemic. Education; business and labor; religion; government; voluntary, civic, and social organizations; and the media can all serve as facilitators or as barriers to creating the environment--at the national, regional, State, or local level--that will prevent and control the spread of HIV infection and AIDS and support the needs of those already infected. Collectively, they become a comprehensive HIV prevention network with access to and influence on the total public. One of the most significant benefits of this network is the multiplier effect on the limited resources of public health. Therefore, as part of its HIV and AIDS prevention strategy, the Centers for Disease Control (CDC) has developed national partnerships to involve the leadership of business, labor and industry, religious institutions and organizations, and voluntary organizations in HIV and AIDS prevention and service. Some of these partnerships are federally funded, others are not. The national partnership program described in this paper has produced increased resources for HIV education and services and has demonstrated the synergistic benefits resulting from public and private cooperation in addressing the HIV epidemic.

Full Text Available Abstract HIV (Human Immunodeficiency virus causes (acquired immunodeficiency syndrome AIDS, in which the immune system of body totally fails to develop any defense against the foreign invaders. Infection with HIV occurs by transfer of blood, semen, and breast milk. HIV/AIDS is a global problem and it results nearly 25 million deaths worldwide. Developing countries like Pakistan have issues regarding Public Health. Currently, epidemic of HIV/AIDS is established in Pakistan and there is a threat of an expanded HIV/AIDS outbreak in the country. The major reason is that population is engaging in high-risk practices, low awareness about HIV/AIDS, and treacherous blood transfusion practices. A supplementary threat to Pakistan is India because both sharing a border and India is facing a rapidly growing HIV/AIDS epidemic. Local NGOs, National and International organizations are warning that in near future Pakistan may experiences bad situation regarding HIV/AIDS. In the present article we focused current situation of surveillance of HIV/AIDS, its virology, genotype, diagnostics, high-risk groups, reasons of vulnerability in Pakistani population, and the role of different national and international organizations in this situation.

Hispanic/Latino men who have sex with men (MSM) in the United States are disproportionately affected by HIV and other sexually transmitted diseases (STDs); however, no efficacious behavioral HIV/STD prevention interventions are currently available for use with this vulnerable population. We describe the enhancement of HOLA en Grupos, a community-based behavioral HIV/STD prevention intervention for Spanish-speaking Hispanic/Latino MSM that is currently being implemented and evaluated in North Carolina with support from the Centers of Disease Control and Prevention (CDC). Our intervention enhancement process included incorporating local data on risks and context; identifying community needs and priorities; defining intervention core elements and key characteristics; developing a logic model; developing an intervention logo; enhancing intervention activities and materials; scripting intervention delivery; expanding the comparison intervention; and establishing a materials review committee. If the CDC-sponsored evaluation determines that HOLA en Grupos is efficacious, it will be the first such behavioral HIV/STD prevention intervention to be identified for potential use with Hispanic/Latino MSM, thereby contributing to the body of evidence-based resources that may be used for preventing HIV/STD infection among these MSM and their sex partners.
Full Text Available BACKGROUND: Antiretroviral Treatment (ART significantly reduces HIV transmission. We conducted a cost-effectiveness analysis of the impact of expanded ART in South Africa. METHODS: We model a best case scenario of 90% annual HIV testing coverage in adults 15-49 years old and four ART eligibility scenarios: CD4 count <200 cells/mm(3 (current practice, CD4 count <350, CD4 count <500, all CD4 levels. 2011-2050 outcomes include deaths, disability adjusted life years (DALYs, HIV infections, cost, and cost per DALY averted. Service and ART costs reflect South African data and international generic prices. ART reduces transmission by 92%. We conducted sensitivity analyses. RESULTS: Expanding ART to CD4 count <350 cells/mm(3 prevents an estimated 265,000 (17% and 1.3 million (15% new HIV infections over 5 and 40 years, respectively. Cumulative deaths decline 15%, from 12.5 to 10.6 million; DALYs by 14% from 109 to 93 million over 40 years. Costs drop $504 million over 5 years and $3.9 billion over 40 years with breakeven by 2013. Compared with the current scenario, expanding to <500 prevents an additional 585,000 and 3 million new HIV infections over 5 and 40 years, respectively. Expanding to all CD4 levels decreases HIV infections by 3.3 million (45% and costs by $10 billion over 40 years, with breakeven by 2023. By 2050, using higher ART and monitoring costs, all CD4 levels saves $0.6 billion versus current; other ART scenarios cost $9-194 per DALY averted. If ART reduces transmission by 99%, savings from all CD4 levels reach $17.5 billion. Sensitivity analyses suggest that poor retention and predominant acute phase transmission reduce DALYs averted by 26% and savings by 7%. CONCLUSION: Increasing the provision of ART to <350 cells/mm3 may significantly reduce costs while reducing the HIV burden. Feasibility including HIV testing and ART uptake, retention, and adherence should be evaluated.

Full Text Available Alcohol use disorders (AUDs are highly prevalent among people living with HIV/AIDS (PLWHA and are associated with increased HIV risk behaviors, suboptimal treatment adherence, and greater risk for disease progression. We used the ADAPT-ITT strategy to adapt an evidence-based intervention (EBI, the Holistic Health Recovery Program (HHRP+, that focuses on secondary HIV prevention and antiretroviral therapy (ART adherence and apply it to PLWHA with problematic drinking. Focus groups (FGs were conducted with PLWHA who consume alcohol and with treatment providers at the largest HIV primary care clinic in New Orleans, LA. Overall themes that emerged from the FGs included the following: (1 negative mood states contribute to heavy alcohol consumption in PLWHA; (2 high levels of psychosocial stress, paired with few adaptive coping strategies, perpetuate the use of harmful alcohol consumption in PLWHA; (3 local cultural norms are related to the permissiveness and pervasiveness of drinking and contribute to heavy alcohol use; (4 healthcare providers unanimously stated that outpatient options for AUD intervention are scarce, (5 misperceptions about the relationships between alcohol and HIV are common; (6 PLWHA are interested in learning about alcohol’s impact on ART and HIV disease progression. These data were used to design the adapted EBI.
Full Text Available In the HPTN 052 study, transmission between HIV-discordant couples was reduced by 96% when the HIV-infected partner received suppressive antiretroviral therapy (ART. We examined two transmission events where the newly infected partner was diagnosed after the HIV-infected partner (index initiated therapy. We evaluated the sequence complexity of the viral populations and antibody reactivity in the newly infected partner to estimate the dates of transmission to the newly infected partners. In both cases, transmission most likely occurred significantly before HIV-1 diagnosis of the newly infected partner, and either just before the initiation of therapy or before viral replication was adequately suppressed by therapy of the index. This study further strengthens the conclusion about the efficacy of blocking transmission by treating the infected partner of discordant couples. However, this study does not rule out the potential for HIV-1 transmission to occur shortly after initiation of ART, and this should be recognized when antiretroviral therapy is used for HIV-1 prevention.

Despite the recognized need for structural-level HIV prevention interventions that focus on economic empowerment to reduce women's HIV risks, few science-based programs have focused on securing women's land ownership as a primary or secondary HIV risk reduction strategy. The current study focused on a community-led land and property rights model that was implemented in two rural areas of western Kenya where HIV prevalence was high (24-30%) and property rights violations were common. The program was designed to reduce women's HIV risk at the community level by protecting and enhancing women's access to and ownership of land. Through in-depth interviews with 50 program leaders and implementers of this program we sought to identify the strategies that were used to prevent, mediate, and resolve property rights violations. Results included four strategies: (1) rights-based education of both women and men individually and at the community level, (2) funeral committees that intervene to prevent property grabbing and disinheritance, (3) paralegal training of traditional leaders and community members and local adjudication of cases of property rights violations, and (4) referring property rights violations to the formal justice system when these are not resolved at the community level. Study participants underscored that local mediation of cases resulted in a higher success rate than women experienced in the formal court system, underscoring the importance of community-level solutions to property rights violations. The current study assists researchers in understanding the steps needed to prevent and resolve women's property rights violations so as to bolster the literature on potential structural HIV prevention interventions. Future research should rigorously test property rights programs as a structural HIV prevention intervention.

The Niger Delta, according to the Nigerian Ministry of Health, has a disproportionately high HIV infection rate, which is double the national average. The United Nations Development Program attributes the spiraling HIV infection rate in the region to poverty, migration and gender inequality. This paper examines two complementary suppositions: Is the high prevalence of HIV in the Niger Delta related to incompetent leadership and corruption? Is it related to the negative effects of oil exploration in the region? Currently, there is a dearth of research on the effectiveness of government programs or the role of the oil industry on the impact of AIDS in Nigeria. To address this gap, we conducted a survey with 27 internationally renowned experts from diverse disciplines using a three-round modified Delphi to formulate consensus about the impact of weak governance and oil corruption on AIDS in the Niger Delta. Results from the Delphi suggest that these factors and others have exacerbated the transmission of HIV in the region. To mitigate the impact of AIDS in the region, efforts to engage oil companies in implementing HIV prevention programs as part of their corporate environmental responsibility to the community are urgently needed.

Our objective was to evaluate the efficacy of a cultural adaptation of a social cognitive theory-based HIV behavioral prevention program among young rural-to-urban migrants in China. The intervention design and assessment were guided by the Protection Motivation Theory (PMT). The intervention was evaluated through a randomized controlled trial with 6-month and 12-month follow-ups. The primary behavioral outcome was the use of condoms. Other outcome measures include HIV knowledge, condom use knowledge, HIV-related perceptions (PMT constructs), and intention to use condom. The mixed-effects regression models for condom use with regular partners indicated that overall frequency of condom use, condom use in last three sexual acts and proper condom use increased over time for the participants but the increases were significantly greater among the intervention group than the control group at 6-month and 12-month follow-ups. The mixed-effects models for HIV-related perceptions indicated that extrinsic rewards, intrinsic rewards, and response costs decreased while vulnerability, severity, response efficacy, and self-efficacy increased over time for the intervention group. The increases in HIV knowledge, condom use knowledge, and intention to use condom were also significantly greater among the intervention group than the control group. The data in the current study suggested efficacy of a social cognitive theory-based behavioral intervention in increasing condom use among young migrants in China. The intervention also increased protective perceptions and decreased risk perception posited by the theory (i.e., PMT).

Purpose Placebo and randomization are important concepts that must be understood before youth can safely participate in HIV vaccine studies or other biomedical trials for HIV prevention. These concepts are central to the phenomenon of preventive misconception which may be associated with an increase in risk behavior among study participants related to mistaken beliefs. Persuasive messaging, traditionally used in the field of marketing, could enhance educational efforts associated with randomized clinical trials. Methods Two educational brochures were designed to increase knowledge about HIV vaccine clinical trials via 1 and 2-sided persuasive messaging. Through the Adolescent Medicine Trials Network, 120 youth were enrolled, administered a mock HIV vaccine trial consent, and then randomized to receive either no supplemental information or one of the two brochures. Results The 2-sided brochure group in which common clinical trial misconceptions were acknowledgedand then refuted had significantly higher scores on knowledge of randomization and interpretation of side effects than the consent-only control group, and willingness to participate in an HIV vaccine trial was not decreased with the use of this brochure. Conclusion Two sided persuasive messaging improves understanding of the concepts of randomization and placebo among youth who would consider participating in an HIV vaccine trial. Further evaluation of this approach should be considered for at-risk youth participating in an actual trial of a biomedical intervention for HIV prevention. PMID:24613097

Male circumcision is defined as the surgical removal of all or part of the foreskin of the penis and may be practiced as part of a religious ritual, as a medical procedure, or as part of a traditional ritual performed as an initiation into manhood. Since the 1980s, over 30 observational studies have suggested a protective effect of male circumcision on HIV acquisition in heterosexual men. In 2002, three randomised controlled trials to assess the efficacy of male circumcision for preventing HIV acquisition in men commenced in Africa. This review evaluates the results of these trials, which analysed the effectiveness and safety of male circumcision for preventing acquisition of HIV in heterosexual men. To assess the evidence of an interventional effect of male circumcision for preventing acquisition of HIV-1 and HIV-2 by men through heterosexual intercourse We formulated a comprehensive and exhaustive search strategy in an attempt to identify all relevant studies regardless of language or publication status (published, unpublished, in press, and in progress). In June 2007 we searched the following electronic journal and trial databases: MEDLINE, EMBASE, and CENTRAL. We also searched the electronic conference databases NLM Gateway and AIDSearch and the trials registers ClinicalTrials.gov and Current Controlled Trials. We contacted researchers and relevant organizations and checked reference lists of all included studies. Randomised controlled trials of male circumcision versus no circumcision in HIV-negative heterosexual men with HIV incidence as the primary outcome. Two review authors independently assessed study eligibility, extracted data, and graded methodological quality. Data extraction and methodological quality were checked by a third author who resolved differences when these arose. Data were considered clinically homogeneous and meta-analyses and sensitivity analyses were performed. Three large RCTs of men from the general population were conducted in South
Full Text Available ABSTRACTIntroduction:Scientific evidence supports the sinergy between biomedical and behavioral interventions aimed at preventing the transmission of HIV as a strategy to eradicate AIDS.Objective:To characterize comparatively the benefits from biomedical and behavioral interventions to prevent HIV transmission.Methods:Narrative review. We performed a comparative analysis of the benefits of studied interventions by means of estimating the number needed to treat (NNT. Evaluated interventions: counseling activities for behavior change to prevent exposure to HIV; antiretroviral pre-exposure prophylaxis (PrEP and antiretroviral post-exposure prophylasis (PEP for HIV and treatment of serodiscordant couples as a strategy for prevention of HIV transmission (TasP.Results:counseling interventions and TasP have smaller NNTs, equal to, respectively, 11 (95%CI 9 - 18 at 12 months and 34 (95%CI 23 - 54 in 42 months comparatively to PrEP interventions, that resulted in 41 (95%CI 28 - 67 individuals receiving antiretrovirals in order to prevent one case of HIV infection at 36 months for men and serodiscordant couples. PEP interventions are associated with protective effects estimated at 81%. Lack of trials evaluating PEP prevents estimate of NNT.Conclusion:The estimate of the NNT can be a helpful parameter in the comparison between the effectiveness of different behavioral and biomedical HIV prevention strategies. Studies evaluating the benefit and safety of combined behavioral and biomedical interventions are needed, especially considering the attributable fraction of each component. Integration of behavioral and biomedical interventions is required to achieve complete suppression of the virus, and thus reducing viral replication, infectivity and the number of cases.

Highly active antiretroviral therapy has greatly reduced the morbidity and mortality of AIDS. However, many of the antiretroviral drugs are toxic with long-term use, and all currently used anti-HIV agents generate drug-resistant mutants. Therefore, there is a great need for new approaches to AIDS therapy. RNAi is a powerful means of inhibiting HIV-1 production in human cells. We propose to use RNAi for gene therapy of HIV/AIDS. Previously we identified a number of new biologically active siRNAs targeting several moderately conserved regions in HIV-1 transcripts. Here we analyze the heterogeneity of nucleotide sequences in three RNAi targets in sequences encoding the reverse transcriptase and integrase domains of current isolates of HIV-1 subtype A in Russia. These data were used to generate genetic constructs expressing short hairpin RNAs 28-30-bp in length that could be processed in cells into siRNAs. After transfection of the constructs we observed siRNAs that efficiently attacked the selected targets. We expect that targeting several viral genes important for HIV-1 reproduction will help overcome the problem of viral adaptation and will prevent the appearance of RNAi escape mutants in current virus strains, an important feature of gene therapy of HIV/AIDS.

Full Text Available Context: An estimated 430,000 children were newly infected with HIV in 2008, over 90% of them through mother-to-child transmission (MTCT. Without intervention, the risk of MTCT ranges from 20% to 45% as per the World Health Organization (WHO. Aim: To find the uptake of Prevention of Parent to Child Transmission of HIV/AIDS (PPTCT services during pregnancy. Setting and Design: Cross-sectional study. Materials and Methods: Ethical approval and informed consent was taken. Uptake of PPTCT services by the mother was obtained in 222 pregnancies. This was compared with the HIV status of children born to them. Statistical Analysis Used: Percentages. Results: In 25.7% pregnancies, the mothers were tested for HIV. One child was born was to a mother who had tested HIV negative in pregnancy. In 50% of the mother-child pairs, both mother and child received PPTCT. Where both the mother and child received PPTCT, only 13.3% children born were HIV positive as against 40% children who were HIV positive where neither mother nor the child had received PPTCT. Conclusion: Uptake of PPTCT services was low. In countries like India where the chances of parent to child transmission of HIV are likely to be more than in developed countries due to breastfeeding practices, the uptake of PPTCT services should be maximized to decrease the burden of pediatric HIV because even a single pediatric HIV infection counts. All the pregnant women need to be voluntarily tested twice for HIV in pregnancy, in which the second test for HIV may be in late pregnancy.

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.

Isoniazid preventive therapy (IPT) is recognised as an important component of collaborative tuberculosis (TB) and human immunodeficiency virus (HIV) activities to reduce the burden of TB in people living with HIV (PLHIV). However, there has been little in the way of IPT implementation at country level. This failure has resulted in a recent call to arms under the banner title of the 'Three I's' (infection control to prevent nosocomial transmission of TB in health care settings, intensified TB case finding and IPT). In this paper, we review the background of IPT. We then discuss the important challenges of IPT in PLHIV, namely responsibility and accountability for the implementation, identification of latent TB infection, exclusion of active TB and prevention of isoniazid resistance, length of treatment and duration of protective efficacy. We also highlight several research questions that currently remain unanswered. We finally offer practical suggestions about how to scale up IPT in the field, including the need to integrate IPT into a package of care for PLHIV, the setting up of operational projects with the philosophy of 'learning while doing', the development of flow charts for eligibility for IPT, the development and implementation of care prior to antiretroviral treatment, and finally issues around procurement, distribution, monitoring and evaluation. We support the implementation of IPT, but only if it is done in a safe and structured way. There is a definite risk that 'sloppy' IPT will be inefficient and, worse, could lead to the development of multidrug-resistant TB, and this must be avoided at all costs.

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

Background The HIV epidemic in Nigeria is complex with diverse factors driving the epidemic. Accordingly, Nigeria's National Agency for the Control of AIDS is coordinating a large-scale initiative to conduct HIV epidemic appraisals across all states. These appraisals will help to better characterize the drivers of the epidemic and ensure that the HIV prevention programmes match the local epidemic context, with resources allocated to interventions that have the greatest impact locally. Currently, the mapping and size estimation of Female Sex Workers (FSWs) - a major component of the appraisal has been completed in seven states. These states are using the data generated to plan, prioritize and scale-up sub-national HIV prevention programmes. Methodology It involved a two-level process of identifying and validating locations where FSWs solicit and/or meet clients (“hotspots”). In the first level, secondary key informants were interviewed to collect information about the geographic location and description of the hotspots. For the second level, FSWs were interviewed at each hotspot and information on population size estimates, typologies and operational dynamics of the FSWs were collected. Results Across the seven states, a total of 17,266 secondary key informants and 5,732 FSWs were interviewed. 10,233 hotspots were identified with an estimated 126,489 FSWs ranging from 5,920 in Anambra to 46,691 in Lagos. The most common hotspots were bars/nightclubs (30%), hotels/lodges (29.6%), streets (16.6%), and brothels (14.6%). Furthermore, the population density of FSWs (per thousand adult men) across the states ranged from 2 in Anambra to 17 in the Federal Capital Territory.

To examine trends in HIV and related risk behaviors among recognized high-risk groups in Bangladesh, the types and extent of prevention initiatives that have been undertaken, and highlight the immediate needs. Journal publications and conference abstracts and proceedings were reviewed. Experts involved in the development and evaluation of current programs or policy were contacted for official reports and policy documents. The trends in sexual risk behaviors over five rounds of national surveillance were tabulated. Gaps in the ongoing prevention interventions have been assessed in the light of the Anderson-May equation. Periodic surveillance on recognized high-risk groups shows that HIV prevalence has been increasing steadily. In the capital city, HIV prevalence in one subset of a high-risk group is close to the level of a concentrated epidemic (4.9%). The high prevalence of sexual risk behaviors among drug users and sex workers and their clients is alarming. Although a small increase in condom use and a reduction of syphilis have been noted among subsets of high-risk groups in recent years, this is clearly not enough to curb the threat of a possible HIV epidemic. There is an urgent need for a comprehensive prevention program that should include more efforts on education and condom promotion, effective management of all sexually transmitted infections, a screening program for migrant workers, the continuation of both behavioral and serological components of HIV surveillance, and the expansion of surveillance to cover the remaining high-risk groups, with due consideration to the consistency of surveillance indicators.

Antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) reduce HIV-1 transmission within heterosexual HIV-1 serodiscordant couples. Prioritizing couples at highest HIV-1 transmission risk for ART and PrEP would maximize impact and minimize costs. The Partners Demonstration Project is an open-label, delivery study of integrated PrEP and ART for HIV-1 prevention among high risk HIV-1 serodiscordant couples in Kenya and Uganda. We evaluated the feasibility of using a validated risk score that weighs a combination of easily measurable factors (age, children, marital status, male circumcision status, condom use, plasma HIV-1 levels) to identify couples at highest risk for HIV-1 transmission for enrollment. Couples scoring ≥5 met the risk score eligibility criteria. We screened 1694 HIV-1 serodiscordant couples and enrolled 1013. Of the screened couples, 1331 (78.6 %) scored ≥5 (with an expected incidence >3 % per year) and 76 % of these entered the study. The median age of the HIV-1 uninfected partner was 29 years [IQR 26, 36] and 20 % were 50,000 copies/ml. A risk scoring tool identified HIV-1 serodiscordant couples for a demonstration project of PrEP and ART with high HIV-1 risk. The tool may be feasible for research and public health settings to maximize efficiency and minimize HIV-1 prevention costs.

There is limited information on the impact of the HIV/AIDS epidemic on Latino migrant workers (LMWs), although available data indicate that this community is being disproportionally affected. The need for prevention programs that address the specific needs of LMWs is becoming well recognized. HIV prevention interventions that train and employ community health workers are a culturally appropriate way to address the issues of community trust and capacity building in this community. This article describes the Latino Migrant Worker HIV Prevention Program and its efforts to train and engage community health workers in the prevention of HIV among LMWs in South Florida.
Full Text Available Introduction. Burden of HIV in pregnant women follows overall epidemic in India. Hence, it is imperative that prevalence calculations in this group be accurate. The present study was carried out to determine prevalence of HIV in pregnant women attending our hospital, to determine trend of HIV infection and to compare our results with reported prevalence. Methods. All pregnant women are routinely counselled for HIV testing using opt-out strategy. Year-wise positivity and trend were determined in these patients over a period of five years. The positivity in different age groups was determined. Results. 31,609 women were tested of which 279 (0.88% were positive. Positivity showed a declining trend over study period and significant quadratic trend (biphasic, P<0.05 was observed. The positivity in older age group ≥35 years (1.64% was significantly more than younger age groups (0.76% in 15–24-year and 0.94% in 25–34-year age group (P=0.0052. Conclusion. A significant decline in HIV positivity was seen over the study period. Taking into account heterogeneous nature of HIV epidemic even within the same district, analysis at local levels especially using the prevention of parent to child transmission of HIV program data is critical for HIV programming and resource allocation.

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

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

There is also increasing evidence that male partner involvement positively impacts non-HIV related outcomes, such as skilled attendance at delivery, exclusive breastfeeding, uptake of effective contraceptives, and infant immunizations. Despite these associations, male partner involvement remains low, especially when offered in the standard antenatal clinic setting. In this review we explore strategies for improving rates of antenatal male partner HIV testing and argue that the role of male partners in PMTCT must evolve from one of support for HIV-infected pregnant and breastfeeding women to one of comprehensive engagement in prevention of primary HIV acquisition, avoidance of unintended pregnancies, and improved HIV-related care and treatment for the HIV-infected and uninfected women, their partners, and children. Involving men in all components of PMTCT has potential to contribute substantially to achieving virtual elimination of mother-to-child HIV transmission; promoting partner-friendly programs and policies, as well as pursuing research into numerous gaps in knowledge identified in this review, will help drive this process.

Early initiation of antiretroviral therapy (ART) reduces HIV transmission and has health benefits. HIV drug resistance can limit treatment options and compromise use of ART for HIV prevention. We evaluated drug resistance in 85 participants in the HPTN 052 trial who started ART at CD4 counts of 350–550 cells/mm3 and failed ART by May 2011; 8.2% had baseline resistance and 35.3% had resistance at ART failure. High baseline viral load and less education were associated with emergence of resistance at ART failure. Resistance at ART failure was observed in 7/8 (87.5%) participants who started ART at lower CD4 cell counts. PMID:26859828

Full Text Available BACKGROUND: There has been renewed call for the global expansion of highly active antiretroviral therapy (HAART under the framework of HIV treatment as prevention (TasP. However, population-level sustainability of this strategy has not been characterized. METHODS: We used population-level longitudinal data from province-wide registries including plasma viral load, CD4 count, drug resistance, HAART use, HIV diagnoses, AIDS incidence, and HIV-related mortality. We fitted two Poisson regression models over the study period, to relate estimated HIV incidence and the number of individuals on HAART and the percentage of virologically suppressed individuals. RESULTS: HAART coverage, median pre-HAART CD4 count, and HAART adherence increased over time and were associated with increasing virological suppression and decreasing drug resistance. AIDS incidence decreased from 6.9 to 1.4 per 100,000 population (80% decrease, p = 0.0330 and HIV-related mortality decreased from 6.5 to 1.3 per 100,000 population (80% decrease, p = 0.0115. New HIV diagnoses declined from 702 to 238 cases (66% decrease; p = 0.0004 with a consequent estimated decline in HIV incident cases from 632 to 368 cases per year (42% decrease; p = 0.0003. Finally, our models suggested that for each increase of 100 individuals on HAART, the estimated HIV incidence decreased 1.2% and for every 1% increase in the number of individuals suppressed on HAART, the estimated HIV incidence also decreased by 1%. CONCLUSIONS: Our results show that HAART expansion between 1996 and 2012 in BC was associated with a sustained and profound population-level decrease in morbidity, mortality and HIV transmission. Our findings support the long-term effectiveness and sustainability of HIV treatment as prevention within an adequately resourced environment with no financial barriers to diagnosis, medical care or antiretroviral drugs.

Heterosexual transmission accounts for the majority of new human immunodeficiency virus (HIV) cases worldwide. The current approach to investigate HIV heterosexual transmission in animals involves application of virus stock to the vaginal surface, a method that does not reproduce the physiological conditions of vaginal intercourse that influence the rate of transmission. We have previously described efficient infection of conventional mice using EcoHIV/NL4-3 and EcoHIV/NDK, chimeric HIV molecular clones constructed to express all HIV structural and regulatory genes except envelope, which is replaced by a rodent-tropic envelope gene. Here we investigated whether EcoHIV/NDK-infected male mice transmit virus to females during coitus, and the sensitivity of this transmission to HIV pre-exposure prophylaxis and the estrus state. Our general approach was to allow mating between EcoHIV/NDK-infected male mice and uninfected females for 1-7 nights. At 1-6 weeks after mating, mice were euthanized and virus burdens were measured by quantitative PCR (qPCR) amplification of HIV RNA or DNA in peritoneal macrophages, inguinal lymph node cells, spleen cells or vas deferens, or by ELISA for antibodies to HIV Gag. We found that 70-100% of female mice mated to EcoHIV/NDK-infected males acquired infection. Pericoital treatment of females with either 2',3'-dideoxcytidine (ddC) or tenofovir largely prevented their EcoHIV/NDK infection by mating (P<0.05 and P<0.003, respectively). In males, T cells were dispensable for virus transmission. The rate of EcoHIV/NDK sexual transmission to females in estrus declined sharply (P=0.003) but their infection by injection was unaffected, indicating that the local environment in the female reproductive tract influences susceptibility to HIV. We conclude that this system of EcoHIV/NDK transmission during mouse mating reproduces key features of heterosexual transmission of HIV in humans and can be used to investigate its biology and control.

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

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

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

Aim: To assess the cost-effectiveness of peer-based sexual behaviour education interventions in prison settings to prevent primary and secondary HIV infections. Methods: Based on the results of a systematic review of peer-based interventions in prison settings, we developed a Bernoulli model to estimate the number of HIV infections averted, consequent loss of quality-adjusted life years (QALYs) avoided and associated savings in health care costs over a lifetime respectively for a peer-led and...
This PhD project examines the strategy of mobilizing motherhood through two Indonesian women’s organizations - the Pembinaan Kesejahteraan Keluarga (Family Welfare Movement, or PKK) and Tim ODHA Perempuan (Seropositive Women’s Team, or TOP Support) - in the attempt to make prevention of mother-to-child transmission of HIV (PMTCT) programs more socially acceptable. Motherhood and HIV/AIDS are in fact seen as contradictory concepts. However, at a time when PMTCT programs are being promoted, the...

Young, Black men who have sex with men (YBMSM) are disproportionately affected by HIV, and Black Churches may be a source of stigma which can exacerbate HIV risk and contribute to negative health and psychosocial outcomes. Findings from this study are based on 21 semi-structured interviews with pastors and ethnographic observation in six Black Churches. Interview transcripts and field notes were analyzed in MAXQDA using thematic content analysis. Although pastors espoused messages of love and acceptance, they overwhelmingly believed homosexuality was a sin and had difficulty accepting YBMSM into their churches. The tension around homosexuality limited pastors' involvement in HIV prevention efforts, although there still may be opportunities for some churches.

Little is known about HIV infection risks and risk behaviours of refugees living in resource-scarce post-emergency phase camps in Africa. Our study at Nyarugusu Camp in Tanzania, covering systematically selected refugees (n = 1140) and refugees living with HIV/AIDS (PLWHA) (n = 182), revealed that the level of HIV risk of systematically selected refugees increased after displacement, particularly regarding the number having transactional sex for money or gifts, while radio broadcast messages are perceived to promote a base of risk awareness within the refugee community. While condoms are yet to be widely used in the camp, some refugees having transactional sex tended to undertake their own health initiatives such as using a condom, under the influence of peer refugee health workers, particularly health information team (HIT) members. Nevertheless, PLWHA were less faithful to one partner and had more non-regular sexual partners than the HIV-negative group. Our study revealed that community-based outreach by refugee health workers is conducive to risk behaviour prevention in the post-emergency camp setting. It is recommended to increase the optimal use of "radio broadcast messages" and "HIT," which can act as agents to reach out to wider populations, and to strengthen the focus on safer sex education for PLWHA; the aim being to achieve dual risk reduction for both refugees living with and without HIV/AIDS.

Full Text Available Legal debates regarding child participation in HIV research have tended to focus on issues of informed consent. However, much less attention has been given to privacy; accordingly, we classify this as a ‘Cinderella issue’ that has been excluded from ‘the ball’ (academic debate. Here we argue that privacy issues are as important as consent issues in HIV-prevention research. We describe a child’s right to privacy regarding certain health interventions in South African law, and identify four key norms that flow from the law and that could be applied to HIV-prevention research: (i children cannot have an expectation of privacy regarding research participation if they have not given independent consent to the study; (ii children may have an expectation of privacy regarding certain components of the study, such as HIV testing, if they consent independently to such services; (iii children’s rights to privacy in health research are limited by mandatory reporting obligations; (iv children’s rights to privacy in HIV-prevention research may be justifiably limited by the concept of the best interests of the child. We conclude with guidelines for researchers on how to implement these principles in HIV-related research studies.

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.

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

Most HIV prevention for sexual minority men and men who have sex with men targets risk behaviors (e.g., condom use) and helps 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.

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

Young transgender women are at increased risk for HIV infection due to factors related to stigma/marginalization and participation in risky sexual behaviors. To date, no HIV prevention interventions have been developed or proven successful with young transgender women. To address this gap, we developed and pilot tested a homegrown intervention "Life Skills," addressing the unique HIV prevention needs of young transgender women aged 16-24 years. Study aims included assessing the feasibility of a small group-based intervention with the study population and examining participant's engagement in HIV-related risk behaviors pre- and 3-months-post-intervention. Fifty-one (N = 51) young transgender women enrolled in the study. Our overall attendance and retention rates demonstrate that small group-based HIV prevention programs for young transgender women are both feasible and acceptable. Trends in outcome measures suggest that participation in the intervention may reduce HIV-related risk behaviors. Further testing of the intervention with a control group is warranted.

Prevention of Mother-To-Child Transmission (PMTCT) of HIV has been at the forefront of research in the field of HIV/AIDS since the PACTG 076 proved successful in 1994. This was followed by many trials with single, dual, or triple Anti Retroviral Therapy (ART), with or without breast-feeding, with different modes of delivery. These trials aimed and promised to find a relatively simple, low-cost intervention that could virtually eliminate the risk of HIV transmission from mother to child, cutting across all geographic boundaries. However, translation of the findings from most of these research studies into successful national PMTCT programs and health policies has not been optimal. In the west, parent to child transmission of HIV has been virtually eliminated due to universal coverage, screening, planned conception wherever possible, thorough evaluation and appropriate antenatal, intranatal and postnatal interventions. In contrast, in resource limited settings where the magnitude of the problem is the greatest accounting for more than 95 % of all vertical transmissions of HIV, there is a constant struggle dealing with the birth of an infected infant every minute. It is time to make optimal choices to prevent the transmission of HIV from an infected mother to her child and virtually eliminate this largely preventable scourge in children.

The early effectiveness of combinatorial antiretroviral therapy (cART) in the treatment of HIV infection has been compromised to some extent by rapid development of multidrug-resistant HIV strains, poor bioavailability, and cumulative toxicities, and so there is a need for alternative strategies of antiretroviral drug discovery and additional therapeutic agents with novel action modes or targets. From this perspective, we first review current strategies of antiretroviral drug discovery and optimization, with the aid of selected examples from the recent literature. We highlight the development of phosphate ester-based prodrugs as a means to improve the aqueous solubility of HIV inhibitors, and the introduction of the substrate envelope hypothesis as a new approach for overcoming HIV drug resistance. Finally, we discuss future directions for research, including opportunities for exploitation of novel antiretroviral targets, and the strategy of activation of latent HIV reservoirs as a means to eradicate the virus.

Introduction: Current studies of depression among people living with HIV focus on describing its point prevalence. Given the fluctuating nature of depression and its profound impacts on clinical and quality-of-life outcomes, this study aimed to examine the prevalence, recurrence and incidence...... to afford housing-related expenses. Conclusions: Depressive symptoms are prevalent and likely to recur among people living with HIV. Our results support the direction of Ontario's HIV/AIDS Strategy to 2026, which addresses medical concerns associated with HIV (such as depression) and the social drivers...... of health in order to enhance the overall well-being of people living with or at risk of HIV. Our findings reinforce the importance of providing effective mental health care and demonstrate the need for long-term support and routine management of depression, particularly for individuals at high risk. © 2016...
Full Text Available Objective. To investigate barriers and correlates of the use of HIV prevention services and HIV testing behaviors among men who have sex with men in Chongqing. Methods. Three consecutive cross-sectional surveys provided demographic, sexual behavior, HIV/syphilis infection, HIV prevention service, and testing behavior data. Results. Of 1239 participants, 15.4% were infected with HIV, incidence was 12.3 per 100 persons/year (95% CI: 9.2–15.3, 38% of the participants reported ever having unprotected insertive anal sex, 40% ever received free condom/lubricants in the past year, and 27.7% ever obtained free sexually transmitted infection examination/treatment in the past year. Multivariable logistic regression revealed that lower levels of HIV/AIDS related stigmatizing/discriminatory attitudes, full-time jobs, and sex debut with men at a younger age were independently associated with use of free condom/lubricants. Large social networks, higher incomes, and sexual debut with men at a younger age were associated with use of any HIV prevention and HIV testing services. Lower levels of stigmatizing/discriminatory attitudes were also associated with HIV testing. Fearing needles and being unaware of the venues for testing were top barriers for testing service utilization. Conclusion. It is imperative to address HIV/AIDS related stigmatizing/discriminatory attitudes and other barriers while delivering intervention and testing services.
Full Text Available Objective: To describe and quantify the differences in risk behaviours, HIV prevalence and incidence rates by birth cohorts among a group of women in Durban, South Africa. Methods: Cross-sectional and prospective cohort analyses were conducted for women who consented to be screened and enrolled in an HIV prevention trial. Demographic and sexual behaviours were described by five-year birth cohorts. Semiparametric regression models were used to investigate the bivariate associations between these factors and the birth cohorts. HIV seroconversion rates were also estimated by birth cohorts. Results: The prevalence of HIV-1 infection at the screening visit was lowest (20.0% among the oldest (born before 1960 cohorts, while the highest prevalence was observed among those born between 1975 and 79. Level of education increased across the birth cohorts while the median age at first sexual experience declined among those born after 1975 compared to those born before 1975. Only 33.03% of the oldest group reported ever using a condom while engaging in vaginal sex compared to 73.68% in the youngest group; however, HIV and other sexually transmitted infection (STI incidence rates were significantly higher among younger women compared to older women. Conclusions: These findings clearly suggest that demographic and sexual risk behaviours are differentially related to the birth cohorts. Significantly high HIV and STI incidence rates were observed among the younger group. Although the level of education increased, early age at sexual debut was more common among the younger group. The continuing increase in HIV and STI incidence rates among the later cohorts suggests that the future trajectory of the epidemic will be dependent on the infection patterns in younger birth cohorts.

Prenatal HIV counselling and testing is mainly an entry-point to the prevention of mother-to-child transmission of HIV, but it may also play an important role in triggering the development of spousal communication about HIV and sexual risks and thus the adoption of a preventive attitude. In Abidjan, Côte d'Ivoire, we investigated couple communication on STIs and HIV, male partner HIV-testing and condom use at sex resumption after delivery among three groups of pregnant women who were offered prenatal counselling and HIV testing: HIV-infected women, uninfected women, and women who refused HIV-testing. The proportion of women who discussed STIs with their regular partner greatly increased after prenatal HIV counselling and testing in all three groups, irrespective of the women's serostatus and even in the case of test refusal. Spousal communication was related to more frequent male partner HIV-testing and condom use. Prenatal HIV counselling and testing proposal appears to be an efficient tool to sensitize women and their partner to safer sexual practices.
The Amagugu Intervention: A conceptual framework for increasing HIV disclosure and parent-led communication about health and HIV prevention among HIV-infected parents with HIV-uninfected primary school-aged children
Tamsen Jean Rochat
Full Text Available Advances in access to HIV prevention and treatment have reduced vertical transmission of HIV, with most children born to HIV-infected parents being HIV-uninfected themselves. A major challenge that HIV-infected parents face is disclosure of their HIV status to their predominantly HIV-uninfected children. Their children enter middle childhood and early adolescence facing many challenges associated with parental illness and hospitalisation, often exacerbated by stigma and a lack of access to health education and support. Increasingly, evidence suggests that primary school-aged children have the developmental capacity to grasp concepts of health and illness, including HIV, and that in the absence of parent-led communication and education about these issues, HIV-exposed children may be at increased risk of psychological and social problems. The Amagugu intervention is a six-session home-based intervention, delivered by lay counsellors, which aims to increase parenting capacity to disclose their HIV status and offer health education to their primary school-aged children. The intervention includes information and activities on disclosure, health care engagement and custody planning. An uncontrolled pre-post evaluation study with 281 families showed the intervention was feasible, acceptable and effective in increasing maternal disclosure. The aim of this manuscript is to describe the conceptual model of the Amagugu intervention, as developed post-evaluation, showing the proposed pathways of risk that Amagugu aims to disrupt through its intervention targets, mechanisms and activities; and to present a summary of results from the large scale evaluation study of Amagugu to demonstrate the acceptability and feasibility of the intervention model. This relatively low-intensity home-based intervention led to: increased HIV disclosure to children, improvements in mental health for mother and child, and improved health care engagement and custody planning for

The intervention adaptation process included focus groups, expert panels, and the filming of women who spoke about their experiences with pregnancy, drug use, sex risk behaviors, HIV testing and treatment, need for substance abuse treatment, violence, and victimization. The assessment instrument was adapted for pregnant women and the intervention was organized into a 4-session PowerPoint presentation, with an additional session if a woman tested positive for HIV. All sessions and assessment instrument were installed on laptop computers for portability in treatment programs. We pilot tested our adaptation with 59 pregnant African-American women who had used an illicit drug within the past year and were enrolled in substance abuse treatment. At baseline, 41% were currently homeless, 76% were unemployed, 90% had not planned their current pregnancy, and approximately 70% reported drug use since finding out about the pregnancy. This sample of participants rated the intervention sessions and were highly satisfied with their experience, resulting in a mean satisfaction score of 6.5 out of 7. Pregnant African-American women who use drugs need substance abuse treatment that they do not currently access. Woman-focused HIV interventions help to address intersecting risk behaviors and need for treatment prevalent among this vulnerable group.Keywords: African-American woman, HIV prevention pregnancy, drug use, violence, sexual

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

This article draws on the unified theory of behavior change to examine adult community members' participation in a collaborative, community-based HIV prevention program for inner-city youth. Specifically, the impact of a training and mentorship process is examined with a sample of parent facilitators hired to deliver an evidence-based HIV prevention program in Bronx, New York. Findings indicate that the training program impacted four of five key constructs (environmental constraints, habitual behavior, social norms, and self-concept) expected to be related to parents' ability to deliver the program constructs significantly beyond any increase evidenced by the control group (HIV knowledge increased in both groups). Community-level training programs may therefore be an effective medium for increasing caregivers' intention to collaborate in community-based prevention programs.

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

HIV is frequently transmitted in the context of partners in a committed relationship, thus couples-focused HIV prevention interventions are a potentially promising modality for reducing infection. We conducted a systematic review of studies testing whether couples-focused behavioral prevention interventions reduce HIV transmission and risk behavior. We included studies using randomized controlled trial designs, quasi-randomized controlled trials, and nonrandomized controlled studies. We searched five electronic databases and screened 7,628 records. Six studies enrolling 1,084 index couples met inclusion criteria and were included in this review. Results across studies consistently indicated that couples-focused programs reduced unprotected sexual intercourse and increased condom use compared with control groups. However, studies were heterogeneous in population, type of intervention, comparison groups, and outcomes measures, and so meta-analysis to calculate pooled effects was inappropriate. Although couples-focused approaches to HIV prevention appear initially promising, additional research is necessary to build a stronger theoretical and methodological basis for couples-focused HIV prevention, and future interventions must pay closer attention to same-sex couples, adolescents, and young people in relationships.
Full Text Available Female sex workers (FSWs who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers' economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers' relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

Understanding sexual behaviors and vaginal practices of pregnant and breastfeeding women in sub-Saharan Africa is critical to inform HIV prevention strategies during these periods. HIV-uninfected women presenting for antenatal care in western Kenya were enrolled and followed through 36 weeks postpartum. Sexual behavior and vaginal practices were ascertained by structured questionnaires. Logistic regression was used to assess correlates of unprotected sex, vaginal washing, and vaginal drying. Among 1252 women enrolled, 78.4% were married (of whom 15.1% were in polygamous unions), 1.4% had a known HIV-infected partner, and 33.6% had a partner of unknown HIV status. At enrollment, 58.5% reported sex in the past month (94.3% unprotected) and 4.5% reported forced sex. Odds of unprotected sex at enrollment was >11-fold higher in married than in unmarried women (P < 0.001) and lower among women who reported partners of unknown HIV status or HIV-infected compared with HIV-uninfected partners. Median time to postpartum resumption of sex was 7 weeks (interquartile range 4-12). Prevalence of unprotected sex in the past week increased from 6.6% to 60.0% between 2 and 36 weeks postpartum (P < 0.001). Vaginal washing was reported by 60.1% of women at enrollment and prevalence remained stable postpartum; vaginal drying was reported by 17.9% at enrollment and decreased to 6.1% at 36 weeks postpartum (P < 0.001). Vaginal washing and drying were associated with forced sex. High rates of unknown partner HIV status, polygamy, and less frequent condom use among pregnant/postpartum women underscore the need for female-controlled HIV prevention interventions. Vaginal washing and drying may present challenges to microbicide use.
Full Text Available Background: Commercial sex plays an increasingly important role in China’s growing HIV and sexually transmitted infection (STI epidemics. In China, street-based sex workers (SSWs are a subgroup of female sex workers with a particularly high risk of HIV/STI infections but are neglected in responses to HIV. This study assesses changes in HIV voluntary counseling and testing (VCT utilization and high-risk sexual behaviors following a three-month HIV preventive intervention among SSWs in Chongqing, China. Methods: A three-month intervention was conducted by a team of peer educators, outreach workers from community-based organizations and health professionals. It mainly included distribution of free pamphlets and condoms and delivery of onsite and clinic-based VCT. Cross-sectional surveys were conducted prior to (n = 100 and immediately following (n = 112 the intervention to assess its impact. In-depth interviews were conducted among 12 SSWs after the intervention to further explore potential barriers to HIV prevention. Results: The intervention significantly increased SSWs’ participation in VCT (from 2.0%–15.2%, P < 0.001. Despite participants’ improved HIV-related knowledge level (from 24.0%–73.2%, P < 0.001, there were minimal changes in the levels of condom use with clients. Qualitative research revealed that fear of police arrest and stigma were the main barriers to VCT utilization. Low condom use was associated with family financial constraints, inadequate power in condom negotiation, low awareness and misconceptions of HIV infection risks. Conclusion: HIV intervention improved VCT utilization and knowledge but we did not observe an increase in condom use after this short intervention. SSWs faced substantial economic, social and environmental barriers to VCT utilization and condom use.

In their recent paper' Undue inducement: a case study in CAPRISA 008', Mngadi et al conclude that a participant in an HIV prevention study who deliberately concealed her pregnancy was not'unduly induced' to participate by the offer of an experimental product. This paper argues that while the authors' conclusion is sound, the framing of this case study is consistent with the preoccupation in research ethics with the concept of undue inducement, coupled with a highly risk-averse attitude to pregnancy (regardless of whether those risks may be willingly assumed by pregnant women themselves). We suggest that the critical research ethics question raised by Mngadi et al's case study is not 'undue inducement', but the exclusion of pregnant women from research studies where the risks are acceptable to the potential participant, and benefits likely. We also suggest that current regulatory paradigms regarding pregnancy are both overly paternalistic and value the fetus over the mother. In order to ensure timely provision of new HIV prevention agents, we argue that there is a need for expeditious testing of proven effective agents in pregnancy, with due consideration given to situations where preliminary efficacy data exist but fall short of licensure standards. This requires a paradigm shift from researchers, funders, regulators and ethical review bodies towards practices that critically examine the legitimacy of the exclusion of pregnant women on a study-by-study basis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available Introduction: Transmission in serodiscordant couples (SDCs accounts for approximately half of all new HIV infections, both in Kenya and the wider sub-Saharan region (1. With evidence to suggest inconsistent condom use within this population (2, the World Health Organization has recommended two new methods of HIV prevention for SDCs: Treatment as Prevention (TasP and Pre-Exposure Prophylaxis (PrEP. However, there has been little research about the attitudes of SDCs towards these strategies (3, 4; knowledge that is paramount for successfully predicting the acceptability and efficacy of each method, as well as for informing decisions regarding HIV policy changes in Kenya. Methods: An exploratory, qualitative study was conducted in the Muhoroni constituency of Nyando district, Kenya from January to March 2013. Purposive sampling was predominately used to recruit 21 HIV-positive and 17 HIV-negative individuals in a serodiscordant relationship from four hospitals and health centres. During face-to-face semi-structured interviews, topic guides were used to elicit information about participants’ attitudes and preferences towards TasP and PrEP. Collected data underwent framework analysis, allowing the development of overarching categories, sub-themes and inductive interpretation. Results: The majority of participants, irrespective of gender and HIV status, found TasP more acceptable than PrEP. A key factor influencing this decision was HIV-negative participants’ limited motivation to take and adhere to antiretrovirals (ARVs, primarily due to a predominantly external health locus of control, a lack of cultural acceptance of prophylactic medication and concerns about side effects. In addition to this, the likely health improvements TasP offers HIV-positive partners, as well as the attitude that the sick individual should be the first to receive HIV medication, also contributed to this conclusion. Issues of risk compensation were raised, with some HIV

As part of a larger study to examine the feasibility and acceptability of a couples-based HIV-prevention intervention, we conducted formative in-depth interviews with 10 couples to explore topics such as challenges in practising safer sex, HIV-prevention strategies, gender power and violence, and issues of trust and infidelity. In this study, both men and women perceived infidelity as ubiquitous in their social context and were therefore unable to discuss HIV risk and prevention without suspicions of infidelity in their own relationship. This impacted couples' ability openly and effectively to discuss strategies to prevent HIV and thus may have contributed to the limited uptake of HIV-prevention strategies, such as condom use and HIV testing. The contentious nature of safe-sex discussions placed both members of the couple at a higher risk for HIV acquisition within the partnership. This study sheds light on how existing relationship norms in South Africa influence HIV-prevention communication within couples and suggests that new ways of approaching conflictual issues such as mistrust and infidelity are vital in order for HIV-prevention programmes to succeed.
Full Text Available Abstract Background Surgical site infection (SSI are the third most frequently reported nosocomial infection, and the most common on surgical wards. HIV-infected patients may increase the possibility of developing SSI after surgery. There are few reported date on incidence and the preventive measures of SSI in HIV-infected patients. This study was to determine the incidence and the associated risk factors for SSI in HIV-infected patients. And we also explored the preventive measures. Methods A retrospective study of SSI was conducted in 242 HIV-infected patients including 17 patients who combined with hemophilia from October 2008 to September 2011 in Shanghai Public Health Clinical Center. SSI were classified according to Centers for Disease Control and Prevention (CDC criteria and identified by bedside surveillance and post-discharge follow-up. Data were analyzed using SPSS 16.0 statistical software (SPSS Inc., Chicago, IL. Results The SSI incidence rate was 47.5% (115 of 242; 38.4% incisional SSIs, 5.4% deep incisional SSIs and 3.7% organ/space SSIs. The SSI incidence rate was 37.9% in HIV-infected patients undergoing abdominal operation. Patients undergoing abdominal surgery with lower preoperative CD4 counts were more likely to develop SSIs. The incidence increased from 2.6% in clean wounds to 100% in dirty wounds. In the HIV-infected patients combined with hemophilia, the mean preoperative albumin and postoperative hemoglobin were found significantly lower than those in no-SSIs group (P Conclusions SSI is frequent in HIV-infected patients. And suitable perioperative management may decrease the SSIs incidence rate of HIV-infected patients.

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

The Africaid Trust is a grassroots South African non-profit organization that engages youth in HIV prevention by harnessing the popularity of football (i.e. soccer). WhizzKids United, the organization's primary program, operates a 12-week program in elementary schools in Pietermaritzburg, South Africa, which aims to impart knowledge and life skills critical to HIV prevention. The goal of this research was to compare elementary school youth who received the program to youth who only received traditional classroom-based HIV education on health behaviors and HIV-related knowledge and stigma. A secondary objective was to evaluate HIV knowledge, sexual behaviors, attitudes towards HIV and health care seeking behaviors among South African youth in grades 9-12. Elementary students who participated in the program reported greater HIV knowledge and lower HIV stigma (p < .001) than those who had not. The majority of youth in grades 9-12 report having sexual relations (55.6%), despite low levels of HIV testing (29.9%) in this high HIV prevalence region of South Africa. The results highlight the importance of supporting community-based HIV educational initiatives that engage high-risk youth in HIV prevention and the need for youth-friendly health services.

Full Text Available Abstract Background Although HIV and tuberculosis (TB prevalence are high in prisons throughout sub-Saharan Africa, little research has been conducted on factors related to prevention, testing and treatment services. Methods To better understand the relationship between prison conditions, the criminal justice system, and HIV and TB in Zambian prisons, we conducted a mixed-method study, including: facility assessments and in-depth interviews with 246 prisoners and 30 prison officers at six Zambian prisons; a review of Zambian legislation and policy governing prisons and the criminal justice system; and 46 key informant interviews with government and non-governmental organization officials and representatives of international agencies and donors. Results The facility assessments, in-depth interviews and key informant interviews found serious barriers to HIV and TB prevention and treatment, and extended pre-trial detention that contributed to overcrowded conditions. Disparities both between prisons and among different categories of prisoners within prisons were noted, with juveniles, women, pre-trial detainees and immigration detainees significantly less likely to access health services. Conclusions Current conditions and the lack of available medical care in Zambia's prisons violate human rights protections and threaten prisoners' health. In order to protect the health of prisoners, prison-based health services, linkages to community-based health care, general prison conditions and failures of the criminal justice system that exacerbate overcrowding must be immediately improved. International donors should work with the Zambian government to support prison and justice system reform and ensure that their provision of funding in such areas as health services respect human rights standards, including non-discrimination. Human rights protections against torture and cruel, inhuman or degrading treatment, and criminal justice system rights, are

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.
Full Text Available Abstract Background Malawi is reassessing its HIV prevention strategy in the light of a limited reduction in the epidemic. No community based incidence studies have been carried out in Malawi, so estimates of where new infections are occurring require the use of mathematical models and knowledge of the size and sexual behaviour of different groups. The results can help to choose where HIV prevention interventions are most needed. Methods The UNAIDS Mode of Transmission model was populated with Malawi data and estimates of incident cases calculated for each exposure group. Scenarios of single and multiple interventions of varying success were used to identify those interventions most likely to reduce incident cases. Results The groups accounting for most new infections were the low-risk heterosexual group - the discordant couples (37% and those who had casual sex and their partners (a further 16% and 27% respectively of new cases. Circumcision, condoms with casual sex and bar girls and improved STI treatment had limited effect in reducing incident cases, while condom use with discordant couples, abstinence and a zero-grazing campaign had major effects. The combination of a successful strategy to eliminate multiple concurrent partners and a successful strategy to eliminate all infections between discordant couples would reduce incident cases by 99%. Conclusions A revitalised HIV prevention strategy will need to include interventions which tackle the two modes of transmission now found to be so important in Malawi - concurrency and discordancy.

In 1988 a group of pediatricians, developmental, clinical, child and social psychologists, anthropologists and health educators began researching in Baltimore, Maryland on an HIV prevention intervention, Focus on Youth. Over the next 25 years the questions being addressed by Focus on Youth, reflected those of the global HIV research experience. During the first phase, the questions being addressed by the broader research community included: Can HIV risk behaviors be purposefully impacted by behavioral interventions? If so, how do successful interventions differ from those that are not effective? Are theory-based interventions more likely to be effective than information-only based interventions? Can theories be translated into culturally and developmentally appropriate interventions including those that are appropriate for children and adolescents? Should parents be involved--and if so, how? During its next phase, the Focus on Youth team increasingly became concerned with a disturbing reality. A large number of interventions had been developed and some had been shown to have evidence of impact. But virtually all of these interventions had been conducted in the USA or Europe. The questions facing researchers included: With the global burden of HIV disproportionately impacting Low and Middle Income Countries (LMIC), especially those in southern Africa, the Caribbean and parts of Asia, what is known about the effectiveness of western-based interventions in these culturally, racially and economically disparate settings? With the exciting proliferation of interventions, federal agencies in the USA and international agencies including UNAIDS realized the importance of assessing the research portfolio and developing metrics of effectiveness. The questions during this phase included: What is an "effective" intervention? How are effective interventions implemented in a new setting? This phase merged with the next phase as researchers and public health workers realized that
Four million people of the global total of 35 million with HIV infection are from South-East Asia. ART is currently utilized by 15 million people and has led to a dramatic decline in the mortality rate, including those in low- and middle-income countries. A reduction in sexually transmitted HIV and in comorbidities including tuberculosis has also followed. Current recommendations for the initiation of antiretroviral therapy in people who are HIV+ are essentially to initiate ART irrespective of CD4 cell count and clinical stage. The frequency of HIV testing should be culturally specific and based on the HIV incidence in different key populations but phasing in viral load technology in LMIC is an urgent priority and this needs resources and capacity. With the availability of simplified potent ART regimens, persons with HIV now live longer. The recent WHO treatment guidelines recommending routine HIV testing and earlier initiation of treatment should be the stepping stone for ending the AIDS epidemic and to meet the UNAIDS mission of 90*90*90.

The new prevalence data regarding the estimated global number of human immunodeficiency virus positive (HIV+) cases,i.e.,including people who are either aware or unaware of their HIV infection in 2010,lead many to wonder why the increase in incidence has reached today's unprecedented level and escalated within such a short time.This,in spite of prevention campaigns in countries affected by HIV/acquired immune deficiency syndrome (AIDS) with their urgent messages aimed at preventing HIV transmission by promoting changes in individual's behavior.This article analyzes the background of the prevention strategies,in particular their political,social and legal concepts in terms of human rights,and reveals traits of human behavior not considered thus far.A radical reappraisal is necessary,at social and legislative levels,as well as options additional to current concepts.When ethical issues come up,they become blamed for outmoded moralistic positions.However,ignoring the reality has led to dire consequences from prioritizing individual human rights over society's collective need to prevent the spread of HIV.

Full Text Available Abstract Background From 2000–2002, the Centers for Disease Control and Prevention (CDC funded a study that was designed to improve the information available to program planners about the geographic distribution of CDC-funded HIV prevention services provided by community-based organizations (CBOs. Program managers at CDC recognized the potential of a geographic information system (GIS to organize and analyze information about HIV prevention services and they made GIS a critical component of the study design. The primary objective of this study was to construct a national, geographically-referenced database of HIV prevention services provided by CDC-funded CBOs. We designed a survey instrument to collect information about the geographic service areas where CBOs provided HIV prevention services, then collected data from CBOs that received CDC funding for these services during fiscal year 2000. We developed a GIS database to link questionnaire responses with GIS map layers in a manner that would incorporate overlapping geographies, risk populations and prevention services. We collected geographic service area data in two formats: 1 geopolitical boundaries and 2 geographic distance. Results The survey response rate was 70.3%, i.e. 1,020 of 1,450 community-based organizations responded. The number of HIV prevention programs administered by each CBO ranged from 1 to 23. The survey provided information about 3,028 prevention programs, including descriptions of intervention types, risk populations, race and ethnicity, CBO location and geographic service area. We incorporated this information into a large GIS database, the HIV Prevention Services Database. The use of geopolitical boundaries provided more accurate results than geographic distance. The use of a reference map with the questionnaire improved completeness, accuracy and precision of service area data. Conclusion The survey instrument design and database development procedures that we used

HIV infection among men who have sex with men, particularly in Thai urban settings and among younger cohorts, is escalating. HIV testing and counseling (HTC) are important for prevention and obtaining treatment and care. We examine data from a 2013 survey of males, 15-24 years, reporting past-year sex with a male and living in Bangkok or Chiang Mai. Almost three quarters of young MSM (YMSM) in Bangkok and only 27 % in Chiang Mai had an HIV test in the previous year. Associations for HIV testing varied between cities, although having employment increased the odds of HIV testing for both cities. In Bangkok, family knowledge of same sex attraction and talking to parents/guardians about HIV/AIDS had higher odds of HIV testing. Expanded HTC coverage is needed for YMSM in Chiang Mai. All health centers providing HTC, including those targeting MSM, need to address the specific needs of younger cohorts.

A technique for the prevention of staphylococcal adhesion by electrical current exposure was investigated. Teflon coupons were exposed to a continuous flow of 103 cfu/ml Staphylococcus epidermidis with or without 2000 microA DC electrical current delivered by electrodes on opposite sides of a coupon, touching neither each other nor the coupon. A mean 3.46 (SD, 0.20) and 5.70 (SD, 1.03) log10 cfu/cm2 were adhered to the non-electrical current exposed coupons after 4 h and 24 h, respectively. A mean 2.46 (SD, 0.31) and 1.47 (SD, 0.73) log10 cfu/cm2 were adhered after 4 h and 24 h with exposure to 2000 microA electrical current delivered by graphite electrodes. A mean 2.21 (SD, 0.14) and 0.55 (SD, 0.00) log10 cfu/cm2 were adhered after 4 h and 24 h with exposure to 2000 microA electrical current delivered by stainless steel electrodes. Electrical current may be useful in the prevention of staphylococcal adhesion to biomaterials.
Full Text Available During an HIV-1 prevention clinical trial in East Africa, we observed 16 cases of primary HIV-1 infection in women coincident with pregnancy or breastfeeding. Nine of eleven pregnant women initiated rapid combination antiretroviral therapy (ART, despite having CD4 counts exceeding national criteria for ART initiation; breastfeeding women initiated ART or replacement feeding. Rapid ART initiation during primary HIV-1 infection during pregnancy and breastfeeding is feasible in this setting.

Men who have sex with men (MSM) are one of the most affected populations by HIV/AIDS. Over the last years an increase of cases has been reported in younger groups. The Center for Disease Control and Prevention has stated that stigma and homophobia may have a profound impact on the lives of MSM, and could influence them to engage in HIV risky behaviors. In the U.S and Puerto Rico, an increase in HIV cases among young MSM has been reported. For the period of 2005-2009 an increase of HIV cases was reported with 4.3% in the age group of 13-24 and 55.6% in the age group of 25-34. Understanding the dynamics related HIV risk behaviors among young MSM requires transcending traditional individual behavior oriented perspectives in order to adopt a more comprehensive socio-structural approach. In this manuscript we present a critical analysis of HIV prevention issues among young MSM in Puerto Rico. PMID:25678720

Full Text Available It is important to understand how women's sexual practices may be influenced by male circumcision (MC as an HIV prevention effort. Women's beliefs about MC and sexual behaviour will likely influence the scale-up and uptake of medical MC. We conducted qualitative interviews with 30 sexually active women in Kisumu, Kenya. Women discussed MC related to perceived health benefits, condom use, sexual behaviour, knowledge of susceptibility to HIV and sexually transmitted infections (STIs, circumcision preference, and influence on circumcision uptake. Respondents had a good understanding of the partial protection of MC for acquisition of HIV for men. Women perceived circumcised men as cleaner, carrying fewer diseases, and taking more time to reach ejaculation. Male's circumcision status is a salient factor for women's sexual decision making, including partner choice, and condom use. It will be important that educational information affirms that MC provides only partial protection against female to male transmission of HIV and some STIs; that other HIV and STI prevention methods such as condoms need to be used in conjunction with MC; that MC does not preclude a man from having HIV; and that couples should develop plans for not having sex while the man is healing.

As part of the HPTN 065 study in the Bronx, New York and Washington, the authors, we surveyed clinicians to assess for shifts in their practices and attitudes around HIV treatment and prevention. Antiretroviral therapy (ART)-prescribing clinicians at 39 HIV care sites were offered an anonymous Web-based survey at baseline (2010-2011) and at follow-up (2013). The 165 respondents at baseline and 141 respondents at follow-up had similar characteristics-almost 60% were female, median age was 47 years, two-thirds were physicians, and nearly 80% were HIV specialists. The percentage who reported recommending ART irrespective of CD4 count was higher at follow-up (15% versus 68%), as was the percentage who would initiate ART earlier for patients having unprotected sex with partners of unknown HIV status (64% versus 82%), and for those in HIV-discordant partnerships (75% versus 87%). In line with changing HIV treatment guidelines during 2010 to 2013, clinicians increasingly supported early ART for treatment and prevention.
Migrant women living with HIV in Europe: are they facing inequalities in the prevention of mother-to-child-transmission of HIV?: The European Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC) study group in EuroCoord.

In pregnancy early interventions are recommended for prevention of mother-to-child-transmission (PMTCT) of HIV. We examined whether pregnant women who live with HIV in Europe and are migrants encounter barriers in accessing HIV testing and care. Four cohorts within the European Pregnancy and Paediatric HIV Cohort Collaboration provided data for pooled analysis of 11 795 pregnant women who delivered in 2002-12 across ten European countries. We defined a migrant as a woman delivering in a country different from her country of birth and grouped the countries into seven world regions. We compared three suboptimal PMTCT interventions (HIV diagnosis in late pregnancy in women undiagnosed at conception, late anti-retroviral therapy (ART) start in women diagnosed but untreated at conception and detectable viral load (VL) at delivery in women on antenatal ART) in native and migrant women using multivariable logistic regression models. Data included 9421 (79.9%) migrant women, mainly from sub-Saharan Africa (SSA); 4134 migrant women were diagnosed in the current pregnancy, often (48.6%) presenting with CD4 count <350 cells/µl. Being a migrant was associated with HIV diagnosis in late pregnancy [OR for SSA vs. native women, 2.12 (95% CI 1.67, 2.69)] but not with late ART start if diagnosed but not on ART at conception, or with detectable VL at delivery once on ART. Migrant women were more likely to be diagnosed in late pregnancy but once on ART virological response was good. Good access to antenatal care enables the implementation of PMTCT protocols and optimises both maternal and children health outcomes generally.

Full Text Available Despite efforts to curb the spread of HIV amongst the youth and its positive indication of success in Kenya, the epidemic continues to pose serious challenges to these efforts amongst all demographic groupings across Kenya. This article presents findings of a qualitative study involving 45 youth and 23 Islamic leaders from Lamu, Kenya. The study looked at participant’s perceptions of HIV/AIDS. It also explored participant’s perceptions on what they see as the factors influencing HIV transmission amongst the Lamu youth. Additionally a literature review was used together with the study findings to identify elements for an Islamic based HIV prevention intervention. Our findings indicated that both the youth and religious leaders’ perceptions of HIV/AIDS comprise a mixture of facts and misconceptions. The participants identified idleness, drug abuse and premarital sex as key factors contributing to the risk of HIV infection amongst the Lamu youth. The symbiotic relationship between religious leaders and youth on various aspects of daily practices was evident throughout the study thereby suggesting the importance of working with both in addressing HIV/AIDS in Lamu.

Ageism, in the form of prejudice, stereotyping, and discrimination targeting older adults, represents a barrier to addressing the graying of the HIV epidemic. There is widespread misperception on the part of older adults themselves, as well as service providers and society in general that HIV risk is low as one ages. In addition, internalized ageism may play a role in poorer physical and mental health outcomes, as the negative stereotypes associated with aging become a self-fulfilling prophecy. A number of steps can be taken to address HIV and aging in the context of ageism with regard to: prevention, education, and outreach; treatment guidelines for older adults with HIV; funding to address the aging of the epidemic; engagement of communities, health and social service organizations, and other providers around mental health and social support, and addressing the needs of special populations. Caring for an aging population with HIV represents a challenge, which is exacerbated in low and/or middle-income countries that typically lack the infrastructure of high resource settings. How we address the aging-related issues of the HIV epidemic across regions and settings could serve as a model in dealing with aging in our society in general regardless of HIV status.

Social media technologies offer new approaches to HIV prevention and promotion of testing. We examined the efficacy of the Harnessing Online Peer Education (HOPE) social media intervention to increase HIV testing among men who have sex with men (MSM) in Peru. In this cluster randomised controlled trial, Peruvian MSM from Greater Lima (including Callao) who had sex with a man in the past 12 months, were 18 years of age or older, were HIV negative or serostatus unknown, and had a Facebook account or were willing to create one (N=556) were randomly assigned (1:1) by concealed allocation to join intervention or control groups on Facebook for 12 weeks. For the intervention, Peruvian MSM were trained and assigned to be HIV prevention mentors (peer-leaders) to participants in Facebook groups. The interventions period lasted 12 weeks. Participants in control groups received an enhanced standard of care, including standard offline HIV prevention available in Peru and participation in Facebook groups (without peer leaders) that provided study updates and HIV testing information. After accepting a request to join the groups, continued participation was voluntary. Participants also completed questionnaires on HIV risk behaviours and social media use at baseline and 12 week follow-up. The primary outcome was the number of participants who received a free HIV test at a local community clinic. The facebook groups were analysed as clusters to account for intracluster correlations. This trial is registered with ClinicalTrials.gov, number NCT01701206. Of 49 peer-leaders recruited, 34 completed training and were assigned at random to the intervention Facebook groups. Between March 19, 2012, and June 11, 2012, and Sept 26, 2012, and Dec 19, 2012, 556 participants were randomly assigned to intervention groups (N=278) or control groups (N=278); we analyse data for 252 and 246. 43 participants (17%) in the intervention group and 16 (7%) in the control groups got tested for HIV (adjusted

Background Social media technologies are newly emerging tools that can be used for HIV prevention and testing in low- and middle-income countries, such as Peru. This study examined the efficacy of using the Harnessing Online Peer Education (HOPE) social media intervention to increase HIV testing among men who have sex with men (MSM) in Peru. Methods In a cluster randomized controlled trial with concealed allocation, Peruvian MSM from Greater Lima/Callao (N = 556) were randomly assigned to join private intervention or control groups on Facebook for 12 weeks. In the intervention condition, forty-nine Peruvian MSM were trained and randomly assigned to be HIV prevention mentors to participants via Facebook groups over 12 weeks. Control participants received an enhanced standard of care, including standard offline HIV prevention available in Peru as well as participation in Facebook groups (without peer leaders) that provided study updates and HIV testing information. After accepting a request to join the groups, continued participation was voluntary. Participants could request a free HIV test at a local community clinic, and completed questionnaires on HIV risk behaviors and social media use at baseline and 12-week follow-up. Findings Between March 19, 2012, and June 11, 2012, and Sept 26, 2012, and Dec 19, 2012, 556 participants were randomly assigned to intervention groups (N=278) or control groups (N=278); we analyse data for 252 and 246. 43 participants (17%) in the intervention group and 16 (7%) in the control groups got tested for HIV (adjusted odds ratio 2.61, 95% CI 1.55–4.38). No adverse events were reported. Retention at 12-week follow-up was 90%. Across conditions, 7 (87.5%) of the 8 participants who tested positive were linked to care at a local clinic. Interpretation Development of peer-mentored social media communities seemed to be an effective method to increase HIV testing among high-risk populations in Peru.: Results suggest that the HOPE social

Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome. Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Over the past few years in France, the incidence of human immunodeficiency virus (HIV) has not decreased. Among the most frequent sexually transmissible diseases (STD) in France (condyloma, genitoanal herpes, chlamydia infections), certain STD, considered as negligible, have reappeared: gonorrhoea and syphilis affect male homosexuals and, to a lesser degree, men and women whose epidemiological profile remains to be determined. The health organization is not in favour of associating STD with HIV in its anti-aids strategy. However, acute STD are not only indicator of habits at risk for HIV, but are also potent co-factors of its sexual transmission. Fighting against HIV without creating a dialogue on STD is a waste of time and efficiency. From our experience with the STD, anonymous and free screening and the inter-disciplinary health education centres, we recommend the following: improved screening for HIV and other STD: concomitantly whenever possible, less invasive, free or reimbursed STD sampling, reliable and standardized techniques (polymerisation chain reaction or PCR and derivatives), itinerant screening for STD for persons who do not consult; ensured early, medical, social and psychological care of HIV and STD, emphasising the importance of compliance to treatment and prevention; ensured easy access and low cost of the male and female condoms; renewal and diversification of health relays, particularly in the private sector; staff training on STD and their epidemiological novelty; insisting on a transversal (HIV-other STD, curative-preventive, among others) and pragmatic approach (intervention studies resulting in local action); renewal of the information and advice for the public: information on the relationship between HIV and other STD, on the frequent STD that are lesser known, such as condyloma and chlamydia infections, emphasis on compliance to prevention measures (abstinence or use of condoms) during at least three months after a risk of HIV

More than 80% of cases of HIV infection in Africa are attributed to heterosexual transmission, and most prevention efforts have focused upon checking the sexual spread of HIV. A range of interventions have been implemented over the past 10-15 years in different countries throughout the continent. The nature of the activities depends upon the stage of the epidemic, the target population, the funding level, the level of policy support, donor interests, and the capabilities of implementing agencies in the public and private sectors. Despite reports of some encouraging results, the epidemic remains powerful, dynamic, and spreading. Slowing the HIV/AIDS epidemic in Africa will probably require comprehensive, integrated, and multisectoral programs. Most programs to date, however, intervene almost exclusively at the individual level. The authors describe the evolution of intervention programs to prevent the sexual transmission of HIV in sub-Saharan Africa, discuss lessons learned from programs, and identify gaps in the existing knowledge. Sections review interventions to prevent the sexual transmission of HIV, STD treatment, promoting condoms and making them more available, and behavior change interventions.

Abstract In this article, I draw from an ongoing ethnographic study of HIV prevention for gay, bisexual, and 'men who have sex with men' to develop an institutional analysis of HIV behavioral intervention science and praxis. I approach this analysis through the lens of the social worlds framework, focusing on the institutional arena in which HIV behavioral interventions are devised and executed. Toward this end, I focus on two fundamental points of contention that lie at the heart of the prevention enterprise and put its social organization in high relief: (1) conceptions of health and lifestyle practices and (2) attributions of expertise. These core contentions reveal less the steady advance of normal science than an arena of actors ensconced in boundary work and jurisdictional struggles over how to engineer behavior change and reduce the scale of the HIV epidemic. Their resolution, I argue, has occurred in a historically contingent process determined by the political economy of the US HIV prevention arena and the differential structural location of its social worlds.

RNA interference (RNAi) provides a powerful tool to silence specific gene expression and has been widely used to suppress host factors such as CCR5 and/or viral genes involved in HIV-1 replication. Newer nuclease-based gene-editing technologies, such as zinc finger nucleases (ZFN), transcription activator-like effector nucleases (TALEN) and the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system, also provide powerful tools to ablate specific genes. Because of differences in co-receptor usage and the high mutability of the HIV-1 genome, a combination of host factors and viral genes needs to be suppressed for effective prevention and treatment of HIV-1 infection. Whereas the continued presence of small interfering/short hairpin RNA (si/shRNA) mediators is needed for RNAi to be effective, the continued expression of nucleases in the gene-editing systems is undesirable. Thus, RNAi provides the only practical way for expression of multiple silencers in infected and uninfected cells, which is needed for effective prevention/treatment of infection. There have been several advances in the RNAi field in terms of si/shRNA design, targeted delivery to HIV-1 susceptible cells, and testing for efficacy in preclinical humanized mouse models. Here, we comprehensively review the latest advances in RNAi technology towards prevention and treatment of HIV-1.

We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM.

In India, phase-I human clinical trials for a preventive HIV vaccine are being conducted at Pune and Chennai Centres. In order to find out the willingness of populations at risk to participate in future preventive HIV vaccine trials (HIVVTs) and to assess the factors that enhance or deter them from participation, a study was conducted at Chennai and Madurai in Tamil Nadu. This cross-sectional study was conducted among transport workers, people attending sexually transmitted infection clinics, injection drug users, men having sex with men, women in sex industry and a representative sample of monogamous married women, by employing measurement scales. A structured questionnaire on knowledge and attitudes about the HIV vaccine was used to measure the participants' knowledge and attitudes about HIV vaccine and HIVVTs. Of the 112 participants, 67 (60%) were men. Mean age of the respondents was 32 yr; 68 per cent were high school educated. Majority of respondents were willing to participate in a future HIVVT and the reasons were altruism, protection from HIV, and support for the researchers. Major concerns were vaccine efficacy, side effects of the vaccine and the impact of a HIV vaccine on the participants' lives. Majority (85%) agreed that sex without condom would not be safe despite the availability of an HIV vaccine. It is likely that high-risk volunteers will be willing to enroll in HIVVTs. Barriers and concerns should be dealt with carefully by providing correct information. Also there is a need for more education to ensure participants' understanding of key concepts of HIV vaccine trial.

This piece begins with a brief literature review that focuses upon how media attempt to make sense of news events and construct meaning about HIV/AIDS. We then focus specifically on a linguistic process identified in French dailies in articles about the prevalence and incidence of HIV/AIDS, namely, the presence of certain adverbs. The impact of this linguistic process is also investigated in an experimental study. The results indicated that participants who were exposed to a message within which epidemiological data were marked by such adverbs compared to those who processed a message without such an adverbial marking expressed a higher level of perceived risk and declared a stronger intention to use a condom and to practice a screening test. They also judged the epidemiological situation as more serious and were more supportive of a coercive management of the epidemic. These effects also appeared when the message referred to a sexually transmitted infection with which the subjects were not familiar.
Full Text Available Adolescent girls and young women who are at risk for unplanned pregnancy and sexually transmitted infection (STI, including HIV, are frequently counseled to use a hormonal contraceptive to protect against the former and condoms to protect against the latter, for exampe, American College of Obstetricians and Gynecologists, 2011. The present paper reviews the literature on multiple risk messages, compliance with this dual-use recommendation, predictors of dual use, and interventions developed to encourage dual use. Data indicate that simultaneous use of these two methods is not common, and that efforts to encourage dual use have not yielded promising results. An alternative is to recommend condom use alone, since condoms protect very well against STI and HIV, and quite well against pregnancy when used consistently and correctly. The availability of emergency contraception is relevant here. Research utilizing a randomized controlled trial is recommended.

Compared to European-Americans, African-Americans have greater probability of becoming infected with HIV, as well as worse outcomes when they become infected. Therefore, adequate health communications should ensure that they capture the attention of African-Americans and do not perpetuate disadvantages relative to European-Americans. The objective of this report was to examine if racial disparities in attention to health information parallel racial disparities in health outcomes. Participants were clients of a public health clinic (Study 1 n = 64; Study 2 n = 55). Unobtrusive observation in a public health waiting room, message reading times, and response-time on a modified flanker task were used to examine attention to HIV- and flu-information across racial groups. In Study 1, participants were observed for the duration of their time in a public health clinic waiting room (average duration: 31 min). In Study 2, participants completed tasks in a private room at the public health clinic (average duration: 21 min). Across all attention measures, results suggest an interaction between race and information type on attention to health information. In particular, African-Americans differentially attended to information as a function of information type, with decreased attention to HIV- versus flu-information. In contrast, European-Americans attended equally to both HIV- and flu-information. As such, disparities in attention yielded less access to certain health information for African- than European-Americans in a health setting. The identified disparities in attention are particularly problematic because they disadvantage African-Americans at a time of great effort to correct racial disparities. Modifying the framing of health information in ways that ensure attention by all racial groups may be a strategy to increase attention, and thereby reduce disparities in health outcomes. Future research should find solutions that increase attentional access to health

Young women of childbearing age are disproportionately affected by sexually transmitted infections (STIs) including HIV. In particular, young women have more frequent and more serious health problems from STI or HIV infection than men, and among women, African American women have especially high rates of infection. Pregnancy is an important time for beginning or continued STI and HIV prevention behaviors as discontinuing condom use when the contraceptive motivation is gone puts women and their fetuses at risk for contraction of STIs and HIV if they remain sexually active. There are many personal attributes that predict adherence to STI risk reduction behaviors including health related locus of control. The current study surveyed a group of 100 low-income, urban dwelling minority women during their pregnancies to determine whether maternal-fetal attachment, a characteristic specific to pregnancy, favorably influences pregnant women's health related locus of control such that women might be more inclined to engage in preventative STI/HIV risk reduction behaviors. Our findings revealed that while our sample has very high levels of MFA despite the high rate of unplanned pregnancy, condom use is not the method used to reduce the risk of contracting STIs/HIV. Rather, women are more likely to limit their number of sexual partners during pregnancy. While this is beneficial, pregnant women in non-monogamous relationships may discount the importance of condom use during pregnancy. Prenatal care providers can provide education about condom use as a beneficial prenatal care behavior similar to taking prenatal vitamins.

The population within the criminal justice system suffers from various health disparities including HIV and hepatitis C virus (HCV). African American and Latino offenders represent the majority of the offender population. Evidence-based interventions to prevent HIV and HCV among criminal justice clients are scant and usually do not take cultural differences into account. Toward this end, this study describes the process of culturally adapting an HIV/HCV prevention intervention for Latino criminal justice clients in Miami, Florida, by using the ecological validity model. Recommendations for culturally adapting an intervention for Latinos include an emphasis on language and integrating cultural themes such as familism and machismo. © The Author(s) 2016.

The Canadian "Think Again" social marketing HIV/AIDS prevention campaign, adapted from an American effort, encourages gay men to rethink their assumptions about their partners' HIV statuses and the risks of unsafe sex with them. To improve future efforts, existing HIV/AIDS prevention initiatives require critical reflection. While a formal evaluation of this campaign has been carried out elsewhere, here we use the campaign as a social marketing case study to illustrate its strengths and weaknesses, as a learning tool for other campaigns. After describing the campaign and its key results, we assess how it utilized central tenets of the social marketing process, such as formative research and the marketing mix. We then speak to the importance of theoretical influence in campaign design and the need to account for social-contextual factors in safer sex decision making. We conclude with a summary of the lessons learned from the assessment of this campaign.

More than three decades since its discovery, HIV infection remains one of the most aggressive epidemics worldwide, with more than 35 million people infected. In sub-Saharan Africa, heterosexual transmissions represent nearly 80% of new infections, with 50% of these occurring in women. In an effort to stop the dramatic spread of the HIV epidemic, new preventive treatments, such as microbicides, have been developed. Nanotechnology has revolutionized this field by designing and engineering novel highly effective nano-sized materials as microbicide candidates. This review illustrates the most recent advances in nanotech-derived HIV prevention strategies, as well as the main steps required to translate promising in vitro results into clinical trials.

Introduction Indigenous youth are disproportionately represented in new HIV infection rates in Canada. Current and historical contexts of colonisation and racism, disconnection from culture and land, as well as intergenerational trauma resulting from the legacy of residential schools are social drivers that elevate exposure to HIV among Indigenous peoples. Peer-education and arts-based interventions are increasingly used for HIV prevention with youth. Yet limited studies have evaluated longitudinal effects of arts-based approaches to HIV prevention with youth. The authors present a rationale and study protocol for an arts-based HIV prevention intervention with Northern and Indigenous youth in the Northwest Territories (NWT), Canada. Methods and analysis This is a multicentre non-randomised cohort pilot study using a pretest/post-test design with a 12-month follow-up. The target population is Northern and Indigenous youth in 18 communities in the NWT. The aim is to recruit 150 youth using venue-based sampling at secondary schools. Participants will be involved in an arts-based intervention, Fostering Open eXpression among Youth (FOXY). Participants will complete a pretest, post-test survey directly following the intervention, and a 12-month follow-up. The primary outcome is new or enhanced HIV knowledge, and secondary outcomes to include: new or enhanced sexually transmitted infections knowledge, and increased self-esteem, resilience, empowerment, safer sex self-efficacy and cultural connectedness. Mixed effects regression analyses will be conducted to evaluate pretest and post-test differences in outcome measurement scores. Ethics and dissemination This study has received approval from the HIV Research Ethics Board at the University of Toronto (REB: 31602). In addition, the project is currently registered in the NWT with the Aurora Research Institute (Licence: 15741). Trial results will be published according to the Transparent Reporting of Evaluations with

Although the proportion of new HIV infections in the USA among women has decreased over the last few years, still, approximately 20 % of new infections occur annually among adolescent and adult women. The development of effective evidence-based prevention interventions remains an important approach to further decreasing these numbers. Technology-delivered prevention interventions hold tremendous potential due, in part, to their ability to reach beyond the walls of brick-and-mortar intervention sites to engage individuals where they are. While most technology-delivered interventions have focused on adolescents and men who have sex with men, much fewer have specifically targeted adolescent or adult women despite evidence showing that interventions tailored to specific target populations are most effective. We summarize the recently published literature on technology-delivered HIV prevention interventions for US adolescent and adult women and provide suggestions for next steps in this nascent but emergent area of prevention research.
Full Text Available BACKGROUND: National Institute of Mental Health Project Accept (HIV Prevention Trials Network [HPTN] 043 is a large, Phase III, community-randomized, HIV prevention trial conducted in 48 matched communities in Africa and Thailand. The study intervention included enhanced community-based voluntary counseling and testing. The primary endpoint was HIV incidence, assessed in a single, cross-sectional, post-intervention survey of >50,000 participants. METHODS: HIV rapid tests were performed in-country. HIV status was confirmed at a central laboratory in the United States. HIV incidence was estimated using a multi-assay algorithm (MAA that included the BED capture immunoassay, an avidity assay, CD4 cell count, and HIV viral load. RESULTS: Data from Thailand was not used in the endpoint analysis because HIV prevalence was low. Overall, 7,361 HIV infections were identified (4 acute, 3 early, and 7,354 established infections. Samples from established infections were analyzed using the MAA; 467 MAA positive samples were identified; 29 of those samples were excluded because they contained antiretroviral drugs. HIV prevalence was 16.5% (range at study sites: 5.93% to 30.8%. HIV incidence was 1.60% (range at study sites: 0.78% to 3.90%. CONCLUSIONS: In this community-randomized trial, a MAA was used to estimate HIV incidence in a single, cross-sectional post-intervention survey. Results from this analysis were subsequently used to compare HIV incidence in the control and intervention communities. TRIAL REGISTRATION: ClinicalTrials.gov NCT00203749.

Increasing attention is being paid to the potential of anti-retroviral treatment (ART) for HIV prevention. The possibility of eliminating HIV from a population through a universal test and treat intervention, where all people within a population are tested for HIV and all positive people immediately initiated on ART, as part of a wider prevention intervention, was first proposed in 2009. Several clinical trials testing this idea are now in inception phase. An intervention which relies on universally testing the entire population for HIV will pose challenges to human rights, including obtaining genuine consent to testing and treatment. It also requires a context in which people can live free from fear of stigma, discrimination and violence, and can access services they require. These challenges are distinct from the field of medical ethics which has traditionally governed clinical trials and focuses primarily on patient researcher relationship. This paper sets out the potential impact of a population wide treatment as prevention intervention on human rights. It identifies five human right principles of particular relevance: participation, accountability, the right to health, non-discrimination and equality, and consent and confidentiality. The paper proposes that explicit attention to human rights can strengthen a treatment as prevention intervention, contribute to mediating likely health systems challenges and offer insights on how to reach all sections of the population.
