Abstract
ABSTRACT Adolescent girls and young women (AGYW) are vulnerable populations to HIV/AIDS. We conducted a cross-sectional survey among 637 AGYW in Cameroon to study the feasibility and willingness to use mobile applications (apps) for HIV testing, prevention, and treatment. We found that phone ownership is high among AGYW, where 93.9% ( n = 598) of them (median age: 22 years, interquartile range: 21-24 years) had access to a smartphone, 49.5% ( n = 315) frequently searched for health information, and 48.9% ( n = 312) frequently used health-related apps. AGYW's willingness to use mobile apps for HIV testing, prevention, and treatment were 87.9% ( n = 560), 84.4% ( n = 538), and 84.9% ( n = 541), respectively. The high willingness to use apps was associated with older age, HIV testing, and searching for health information on a phone. Barriers to willingness included having no internet access, concerns about internet cost and privacy, and lack of consistent access to a smartphone.

Awareness and uptake of non-occupational post-exposure prophylaxis (nPEP) among gay, bisexual and other men who have sex with men in China: a cross-sectional study. PSYCHOL HEALTH MED 2024; 29:223-235. [PMID: 36124362 DOI: 10.1080/13548506.2022.2125993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 09/14/2022] [Indexed: 10/14/2022]
Abstract
Non-occupational post-exposure prophylaxis (nPEP) is recommended to reduce the likelihood of HIV infection after potential exposure. However, little is known about this practice among Chinese gay, bisexual and other men who have sex with men (GBM). GBM were enrolled from both centers for disease prevention and control (CDCs) and community health centers in six cities in China. Multivariable logistics regression was used to assess factors associated with awareness of and willingness to use nPEP. A total of 516 eligible GBM were included, 67.2% of whom were aware of nPEP, 76.0% were willing to use nPEP, and 2.3% had ever used nPEP. GBM who had college or higher education, had disclosed sexual orientation, had increased number of male sex partners in the last 6 months, and had ever tested for HIV were more likely to be aware of nPEP. Willingness to use nPEP was significantly associated with college or higher education, STI history, gay app use, and awareness of nPEP prior to study. Uptake of nPEP is still low among MSM in China. Efforts are needed to improve awareness of and access to nPEP among GBM, especially those at higher risk of HIV infection.

Injectable controlled-release systems for the prevention and treatment of infectious diseases. J Biomed Mater Res A 2023. [PMID: 37740704 DOI: 10.1002/jbm.a.37615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 09/03/2023] [Accepted: 09/07/2023] [Indexed: 09/25/2023]
Abstract
Pharmaceutical drugs, including vaccines, pre- and post-exposure prophylactics, and chronic drug therapies, are crucial tools in the prevention and treatment of infectious diseases. These drugs have the ability to increase survival and improve patient quality of life; however, infectious diseases still accounted for more than 10.2 million deaths in 2019 before the COVID-19 pandemic. High mortality can be, in part, attributed to challenges in the availability of adequate drugs and vaccines, limited accessibility, poor drug bioavailability, the high cost of some treatments, and low patient adherence. A majority of these factors are logistical rather than technical challenges, providing an opportunity for existing drugs and vaccines to be improved through formulation. Injectable controlled-release drug delivery systems are one class of formulations that have the potential to overcome many of these limitations by releasing their contents in a sustained manner to reduce the need for frequent re-administration and improve clinical outcomes. This review provides an overview of injectable controlled drug delivery platforms, including microparticles, nanoparticles, and injectable gels, detailing recent developments using these systems for single-injection vaccination, long-acting prophylaxis, and sustained-release treatments for infectious disease.

Understanding HIV Pre-Exposure Prophylaxis Questions of U.S. Health Care Providers: Unique Perspectives from the PrEPline Clinical Teleconsultation Service. Telemed J E Health 2023; 29:376-383. [PMID: 35802493 PMCID: PMC10024264 DOI: 10.1089/tmj.2022.0145] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 05/18/2022] [Accepted: 05/31/2022] [Indexed: 11/12/2022] Open
Abstract
Introduction: Fewer than a quarter of people considered to have factors associated with HIV acquisition are prescribed pre-exposure prophylaxis (PrEP) in the United States. Prior studies demonstrate disparities in provider comfort and knowledge regarding PrEP, suggesting a need for provider capacity building to support widespread PrEP availability. This study examined real-world PrEP clinical questions/cases from providers to a teleconsultation service to identify knowledge gaps and improve PrEP-related training materials and clinical guidelines. Methods: The National Clinician Consultation Center (NCCC) PrEPline provides educational teleconsultation services on clinical decision-making related to PrEP for U.S. health care providers. The NCCC PrEP consultation data collected between 2017 and 2020 were reviewed and systematically categorized by clinical topics, subtopics, and complexity levels (low, moderate, and high). Results: Within the study period, the PrEPline provided 1,754 teleconsultations. More than three quarters came from advanced practice nurses and physicians. The topics of questions commonly focused on medication-based HIV prevention strategies (22.7%), PrEP laboratory ordering/monitoring (17.4%), and side effects and contraindications (14.6%). The majority of teleconsultations (57.9%) involved sharing information that was directly available/addressed in the Centers for Disease Control and Prevention (CDC) 2017 PrEP Guidelines (i.e., low complexity). Discussion: The low frequency of consultations from nonphysician and non-nurse practitioner providers may suggest a need for increased training and collaborative opportunities for other types of providers. The high percentage of low-complexity inquiries may reveal a desire for capacity-building materials specifically designed for practicing providers (e.g., abridged versions of guidelines). This study may inform future research, best clinical practices, and aid in the development of training materials to increase providers' HIV prevention comfort and knowledge.

Abstract
OBJECTIVE The HIV preexposure prophylaxis optimization intervention (PrEP-OI) study evaluated the efficacy of a panel management intervention using PrEP coordinators and a web-based panel management tool to support healthcare providers in optimizing PrEP prescription and ongoing PrEP care. DESIGN The PrEP-OI study was a stepped-wedge randomized clinical trial conducted across 10 San Francisco Department of Public Health primary care sites between November 2018 and September 2019. Each month, clinics one-by-one initiated PrEP-OI in random order until all sites received the intervention by the study team. METHODS The primary outcome was the number of PrEP prescriptions per month. Secondary outcomes compared pre- and postintervention periods on whether PrEP was discussed and whether PrEP-related counseling (e.g., HIV risk assessment, risk reduction counseling, PrEP initiation/continuation assessment) was conducted. Prescription and clinical data were abstracted from the electronic health records. We calculated incidence rate ratios (IRR) and risk ratios (RR) to estimate the intervention effect on primary and secondary outcomes. RESULTS The number of PrEP prescriptions across clinics increased from 1.85/month (standard deviation [SD] = 2.55) preintervention to 2.44/month (SD = 3.44) postintervention (IRR = 1.34; 95% confidence interval [CI] = 1.05-1.73; P = 0.021). PrEP-related discussions during clinic visits (RR = 1.13; 95% CI = 1.04-1.22; P = 0.004), HIV risk assessment (RR = 1.40; 95% CI = 1.14-1.72; P = 0.001), and risk reduction counseling (RR = 1.16; 95% CI = 1.03-1.30; P = 0.011) increased from the pre- to the postintervention period. Assessment of PrEP initiation/continuation increased over time during the postintervention period (RR = 1.05; 95% CI = 0.99-1.11; P = 0.100). CONCLUSIONS A panel management intervention using PrEP coordinators and a web-based panel management tool increased PrEP prescribing and improved PrEP-related counseling in safety-net primary care clinics.

'Oh, I don't really want to bother with that:' gay and bisexual young men's perceptions of barriers to PrEP information and uptake. CULTURE, HEALTH & SEXUALITY 2022; 24:1548-1562. [PMID: 34524938 PMCID: PMC8920939 DOI: 10.1080/13691058.2021.1975825] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 08/30/2021] [Indexed: 06/13/2023]
Abstract
Pre-exposure prophylaxis (PrEP), a daily oral pill for HIV prevention demonstrated to be effective for adults, was recently approved by the US Food and Drug Administration for use with young people weighing at least 35 kilograms. Given that young people aged 13-19 years account for a disproportionate share of new US HIV infections, PrEP presents an important opportunity. There has been limited effort, however, to increase PrEP awareness and uptake among young people. While prior work has identified barriers young people face in getting PrEP, effective strategies for overcoming these barriers have not yet been identified. This paper presents results from interviews with 15-19 year old gay and bisexual young men about their knowledge and perceptions of PrEP, and the barriers they perceive. Results suggest that participants were aware of PrEP but confused by the details of insurance coverage and out-of-pocket costs. Participants also felt parents and providers would not be knowledgeable or supportive, and were reluctant to share their own use of PrEP on social media. Suggested next steps include online parent and provider education, systemic health care reform to streamline and simplify access to preventative care and awareness campaigns that meet youth where they are on popular platforms.

HIV Pre-exposure Prophylaxis Uptake and Continuation Among Key Populations in Cameroon: Lessons Learned From the CHAMP Program. J Acquir Immune Defic Syndr 2022; 91:39-46. [PMID: 35536113 PMCID: PMC9377496 DOI: 10.1097/qai.0000000000003012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Accepted: 04/25/2022] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) is proven to be a highly effective HIV prevention method for key populations. However, its scale-up in resource-limited settings remains suboptimal. This paper seeks to describe PrEP initiation and continuation among key populations in Cameroon. METHODOLOGY From June 2019 through October 2020, we collected routine program data on PrEP uptake and continuation among female sex workers (FSWs) and men who have sex with men (MSM) in the Continuum of prevention, care and treatment of HIV/AIDS with Most-at-risk Populations (CHAMP) program in Cameroon. PrEP was offered to clients who tested negative for HIV and were assessed to potentially benefit from PrEP. Using survival analysis, we identified factors associated with PrEP discontinuation over time with significance set at 5%. RESULTS Overall, 27,750 clients were sensitized for PrEP of whom 3,138 persons were eligible to start PrEP and 1,409 (45%; FSW: 691 and MSM: 718) initiated PrEP. The PrEP continuation rate was 37% at 3 months, 28% at 6 months and 19% at 12 months. PrEP discontinuation was significantly higher among FSW than MSM [adjusted hazard ratio (aHR) 1.5 (95% CI: 1.2 to 1.9)] in Yaounde [aHR 1.5 (95% CI: 1.2 to 1.9)] and Bafoussam/Bertoua [aHR 3.1 (2.2-4.5)] relative to Douala. Discontinuation was lower among those with moderate [aHR 0.3 (0.3-0.4)] or good adherence [aHR 0.4 (0.3-0.6)] compared with poor adherence (all P < 0.001). CONCLUSION Differentiated approaches to deliver PrEP, create demand, and provide more intensive support for adherence and continuation may support scale-up of PrEP in Cameroon for equitable and prolonged impact on HIV prevention.

Abstract
Female sex workers (FSW) are disproportionately affected by sexual violence (SV) and HIV. Social and structural barriers limit their access to post-exposure prophylaxis (PEP). Respondent-driven sampling survey in 12 Brazilian cities among 4188 FSW aimed to estimate the rates of SV and factors associated with access to PEP use among FSW who experienced SV. The prevalence of SV was 26.3% (1199). Of the 1199, 7.5% sought out healthcare and used PEP, 19% sought out healthcare, but did not use PEP, and 73.5% did not seek out healthcare after SV. Factors associated with PEP use included PEP awareness, participation in HIV/STI prevention workshops, and disclosure of FSW status in healthcare services. Although Brazil has a PEP program free of charge, it is not readily accessible, even for FSW who seek out healthcare. The development of effective strategies to link FSW to HIV preventive services is urgently needed.

Abstract
Lack of healthcare provider knowledge, capacity, and willingness to prescribe
PrEP are barriers to PrEP delivery in clinical settings. We implemented the PrEP
Optimization Intervention (PrEP-OI) combining a PrEP Coordinator with an online
panel management tool to assist providers with PrEP uptake, persistence, and
management in 12 San Francisco Department of Public Health Primary Care Clinics.
Medical directors (N = 10) identified important factors to consider prior to
implementation, including shortage of clinical space for coordinators, medical
mistrust, language barriers, and limited lab hours, along with the need for
education of providers and staff and patient outreach. Among 110 providers who
completed a baseline survey, the majority had reservations in asking about
sexual practices and having conversations about PrEP. Providers reported PrEP-OI
increased their efficiency and capacity to manage PrEP patients, and served as a
gateway to additional services. These results highlight the promise of a
provider-based intervention to improve the PrEP continuum and maximize the
impact of PrEP.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) has demonstrated to be a highly effective method for preventing HIV; however, many individuals with PrEP indications are not receiving PrEP. Primary care settings provide an opportunity to offer PrEP to a wide range of patients. In this paper, we describe the PrEP Optimisation Intervention (PrEP-OI), which includes a PrEP Coordinator and a web-based panel management tool (called PrEP-Rx), and is targeted at healthcare providers (HCPs) to increase PrEP uptake and persistence among those at risk for acquiring HIV. METHODS AND ANALYSIS The PrEP-OI study evaluates the efficacy of the PrEP intervention (PrEP Coordinator + PrEP-Rx) to increase PrEP prescriptions through a stepped-wedge design among 10 primary care clinical sites in the San Francisco Department of Public Health. The number of PrEP initiation prescriptions constitute the primary outcome, and we hypothesise that the mean number of PrEP prescriptions written will significantly increase after the clinics initiate PrEP-OI versus before this intervention. Secondary objectives include: 1-differences in PrEP initiation, duration of use and reasons for discontinuation based on patient's age, race/ethnicity and sex/gender, and by clinic and HCP characteristics, 2-sustainability of the intervention during a 12-month follow-up after the stepped-wedge phase, and 3-facilitators and barriers of PrEP delivery and experiences with the proposed PrEP intervention through qualitative interviews with HCPs. The results of this study can provide valuable insight into methods to reduce the burden of PrEP care on HCPs and improve PrEP continuum of care. ETHICS AND DISSEMINATION This study and its protocols have been approved by the University of California, San Francisco (UCSF) Institutional Review Board. Study staff will disseminate findings locally (eg, the UCSF Centre for AIDS Prevention Studies' Community Engagement Core), statewide (eg, the California Department of Public Health's Office of AIDS) and nationally and internationally at conferences related to HIV.

Abstract
This article aims to Identify factors associated with knowledge and use of combined HIV prevention strategies among female sex workers (FSW). Cross-sectional epidemiological study, using the Respondent Driven Sampling (RDS) method. Descriptive analyzes were performed after adjustments required by the RDS method. To investigate factors associated with knowledge of PEP and PrEP and use of the female condom, Poisson regression was applied, using odds ratio as an association measure. FSW not affiliated with NGOs, who did not receive informational material on prevention and / or participated in lectures in the last six months and who do not identify themselves as FSW in healthcare service facilities have less knowledge about PEP and PrEP and use the female condom less frequently. In general, FSW do not have sufficient knowledge and access to combined HIV prevention methods to take advantage of their benefits. We believe that the adoption of different models of care for FSW in partnership with NGOs can be an effective strategy for expanding knowledge and use of HIV prevention methods in Brazil.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) greatly reduces the risk of human immunodeficiency virus (HIV) acquisition, but its optimal delivery strategy remains uncertain. Clinics for sexually transmitted infections (STIs) can provide an efficient venue for PrEP delivery. METHODS To quantify the added value of STI clinic-based PrEP delivery, we used an agent-based simulation of HIV transmission among men who have sex with men (MSM). We simulated the impact of PrEP delivery through STI clinics compared with PrEP delivery in other community-based settings. Our primary outcome was the projected 20-year reduction in HIV incidence among MSM. RESULTS Assuming PrEP uptake and adherence of 60% each, evaluating STI clinic attendees and delivering PrEP to eligible MSM reduced HIV incidence by 16% [95% uncertainty range, 14%-18%] over 20 years, an impact that was 1.8 (1.7-2.0) times as great as that achieved by evaluating an equal number of MSM recruited from the community. Comparing strategies where an equal number of MSM received PrEP in each strategy (ie, evaluating more individuals for PrEP in the community-based strategy, because MSM attending STI clinics are more likely to be PrEP eligible), the reduction in HIV incidence under the STI clinic-based strategy was 1.3 (1.3-1.4) times as great as that of community-based delivery. CONCLUSIONS Delivering PrEP to MSM who attend STI clinics can improve efficiency and effectiveness. If high levels of adherence can be achieved in this population, STI clinics may be an important venue for PrEP implementation.

Abstract
Access to antiretroviral-based HIV prevention has been marked by sex asymmetries, and its effectiveness has been compromised by low clinical follow-up rates. We investigated risk profiles of women who received nonoccupational post-exposure prophylaxis (nPEP), as well as the rates and predictive factors of loss to follow-up after nPEP initiation.Retrospective study evaluating 501 women who received nPEP between 2014 and 2015 at 5 HIV centers (testing centers-VCT, outpatient clinics, and infectious diseases hospital). Risk profiles were drawn based on the characteristics of the women and their sexual partners, and then stratified by sociodemographic indicators and previous use of HIV prevention services. Loss to follow-up (LTFU) was defined as not presenting for follow-up visits or for HIV testing after nPEP initiation. Predictors of LTFU were analyzed by calculating adjusted prevalence ratios (aPRs).Approximately 90% of women had sexual encounters that met the criteria established in the Brazilian guidelines for nPEP. Those who declared to be sex workers (26.5%) or drug users (19.2%) had the highest social vulnerability indicators. In contrast, women who had intercourse with casual partners of unknown HIV risk (42.7%) had higher education and less experience with previous HIV testing (89.3%) or nPEP use (98.6%). Of the women who received nPEP after sexual intercourse with stable partners, 75.8% had HIV-infected partners. LTFU rate was 72.8% and predictors included being Black (aPR = 1.15, 95% confidence interval [CI]: 1.03-1.30), using drugs/alcohol (aPR = 1.15, 95% CI: 1.01-1.32) and having received nPEP at an HIV outpatient clinic (aPR = 1.35, 95% CI: 1.20-1.51) or at an infectious diseases hospital (aPR = 1.37, 95% CI: 1.11-1.69) compared with a VCT. The risk of LTFU declined as age increased (aPR 41-59 years = 0.80, 95% CI: 0.68-0.96).Most women who used nPEP had higher socioeconomic status and were not part of populations most affected by HIV. In contrast, factors that contribute to loss to follow-up were: having increased social vulnerability; increased vulnerability to HIV infection; and seeking nPEP at HIV treatment services as opposed to at a VCT.

Sex, human rights and AIDS: an analysis of new technologies for HIV prevention in the Brazilian context. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 18 Suppl 1:89-103.

Abstract
Worldwide, HIV prevention is challenged to change because clinical trials show the protective effect of technologies such as circumcision, preexposure prophylaxis, and the suppression of viral load through antiretroviral treatment. In the face of demands for their implementation on population levels, the fear of stimulating risk compensation processes and of increasing riskier sexual practices has retarded their integration into prevention programs. In this article, following a narrative review of the literature on risk compensation using the PubMed database, we offer a critical reflection on the theme using a constructionist approach of social psychology integrated to the theoretical framework of vulnerability and human rights. The use of biomedical technologies for prevention does not consistently induce its users to the increase of riskier practices, and variations on the specificity of each method need to be carefully considered. Alternatives to the theories of sociocognitive studies, such as social constructionist approaches developed in the social sciences and humanities fields, indicate more comprehensive interpretations, valuing the notions of agency and rights. The critical analysis suggests priority actions to be taken in the implementation process: development of comprehensive programs, monitoring and fostering dialog on sexuality, and technical information. We highlight the need to implement a human rights-based approach and to prioritize dialog, stressing how complementary these technologies can be to meet different population needs. We conclude by stressing the need to prioritize sociopolitical changes to restore participation, dialog about sexuality, and emphasis on human rights such as core elements of the Brazilian AIDS policy.

Abstract
INTRODUCTION Scientific evidence supports the synergy 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.

Technologies for HIV prevention and care: challenges for health services. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2017; 18 Suppl 1:104-19. [PMID: 26630301 DOI: 10.1590/1809-4503201500050008] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2014] [Accepted: 05/22/2015] [Indexed: 11/22/2022] Open
Abstract
This article aims to consider some relevant challenges to the provision of "new prevention technologies" in health services in a scenario where the "advances" in the global response to AIDS control are visible. We take as material for analysis the information currently available on the HIV post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), treatment as prevention (TASP) and over the counter. The methodology consisted of the survey and analysis of the Biblioteca Virtual em Saúde (BVS: MEDLINE, LILACS, WHOLIS, PAHO, SciELO) articles that addressed the issue of HIV prevention and care in the context of so-called new prevention technologies. The results of the studies show that there is assistance on the ground of clinics for the treatment of disease responses, but there are several challenges related to the sphere of prevention. The articles list some challenges regarding to management, organization of services and the attention given by health professionals to users. The current context shows evidence of the effectiveness of antiretroviral therapy in reducing the risk of HIV transmission, but the challenges for the provision of preventive technologies in health services permeate health professionals and users in their individual dimensions and health services in organizational and structural dimension. Interventions should be made available in a context of community mobilization; there should be no pressure on people to make HIV testing, antiretroviral treatment or for prevention. In the management is responsible for the training of health professionals to inform, clarify and make available to users, partners and family information about the new antiretroviral use strategies.

Abstract
The study examined the attitudes and knowledge of transgender men (trans men) regarding pre-exposure prophylaxis (PrEP) for HIV. Three focus groups of trans men were conducted with a trans male facilitator for a total of 21 participants. Six themes were identified; the range of information about PrEP and possible side effects, the economic realities for trans men, finding a trans-competent provider, trans male sexuality, the importance of contraception, and condom use. Despite identified risk and some information that has been disseminated, many trans men still lack adequate information regarding PrEP. There exist significant barriers to PrEP access for trans men. Participants commented that many providers avoid important discussions regarding sexuality and contraception. The education of health care professionals must include competency in working with transgender populations. More research is needed with regard to interactions between PrEP, testosterone, and hormonal contraception.

Abstract
OBJECTIVE To evaluate the impact of an HIV pre-exposure prophylaxis (PrEP) education intervention on PrEP awareness and use among men who have sex with men (MSM) attending a sexually transmitted diseases (STD) clinic. DATA SOURCES/STUDY SETTING Men who have sex with men STD clinic patients. STUDY DESIGN We estimated a difference-in-differences linear regression model, comparing MSM whose first visit to the clinic was before ("control") or after ("treatment") intervention implementation and controlling for patient. DATA COLLECTION/EXTRACTION We used self-reported data on PrEP awareness and use from STD clinic intake forms. PRINCIPAL FINDINGS Pre-exposure prophylaxis awareness between first and second clinic visits increased 27.2 percentage points (pp) in the treatment group, relative to 13.7 pp in the control group. Similarly, PrEP use increased 7.1 pp in the treatment group versus 2.4 pp in the control group. Based on adjusted estimates, the PrEP intervention increased PrEP awareness by 24 pp (p < .01) and PrEP use by 5 pp (p = .01), increases of 63 percent and 159 percent relative to the 6 months prior to the intervention. CONCLUSION A brief, scalable STD clinic PrEP education intervention led to significantly increased PrEP awareness and use among MSM. Health care providers should consider implementing brief PrEP education interventions in sexual health care settings.

Abstract
The HIV epidemic among Black men and transgender women who have sex with men (BMTW) demands an urgent public health response. HIV point prevalence among this population ranges from 25 to 43%-a rate far exceeding any other group. Pre-exposure prophylaxis (PrEP) for HIV prevention is a very promising prevention tool; however, its full potential to slow the epidemic has yet to be realized. For the current study, random time-location sampling at Black Gay Pride Events was used to collect data from N = 1274 BMTW, from five US cities, reporting HIV-negative/unknown status. In-field HIV testing was also provided to participants. Participants were assessed on awareness and use of PrEP, health care factors, HIV testing history, psychosocial variables, and sex behaviors. About one third of participants were aware of PrEP (39%), and a small percentage of participants were users of PrEP (4.6%). In multivariable analyses, being in a relationship, testing for HIV in the past 6 months, and others being aware of one's sexuality were positively associated with PrEP awareness. Higher levels of internalized homophobia and greater numbers of female sex partners were positively associated with PrEP use, while education and condom use were negatively associated. Based on study findings, messaging and uptake of PrEP needs greater expansion and requires novel approaches for scale-up. Improving linkage to HIV testing services is likely critical for engaging BMTW with PrEP. The potential for PrEP to slow the HIV epidemic is high; however, we must strengthen efforts to ensure universal availability and uptake.

Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) for prevention of HIV infection has demonstrated efficacy in randomized controlled trials and in demonstration projects. For PrEP implementation to result in significant reductions in HIV incidence for men who have sex with men in the United States, sufficient access to PrEP care and continued engagement outside of demonstration projects is required. METHODS We report the results of a follow-up survey of 173 former participants from the Miami and San Francisco sites of the US PrEP Demo Project, administered 4-6 months after study completion. RESULTS Survey respondents continued to frequently access medical care and had a high incidence of sexually transmitted infections after completion of the Demo Project, indicating ongoing sexual risk behavior. Interest in continuing PrEP was high with 70.8% indicating that they were "very interested" in continuing PrEP. Among respondents, 39.9% reported continuation of PrEP after completion of the Demo Project, largely through their primary care providers and frequently at low or no cost. Variability in access and engagement was seen, with participants from the San Francisco site, those with medical insurance, and those with a primary care provider at the end of the Demo Project more likely to successfully obtain PrEP medication. Two respondents reported HIV seroconversion in the period between study completion and the follow-up survey. CONCLUSIONS Additional effort to increase equitable access to PrEP outside of demonstration projects is needed to realize the potential impact of this evidence-based prevention intervention.

Abstract
Sexual assault patients may encounter barriers when accessing, accepting, and completing nonoccupational postexposure prophylaxis (nPEP), such as lacking insurance or an understanding of nPEP. However, less is known about how sexual assault forensic examiner (SAFE) programs' protocols, approaches to discussing nPEP, and community resources may influence nPEP completion. Utilizing a qualitative case study framework, we conducted semistructured interviews with 10 SAFEs from an urban SAFE program in which emergency department physicians write prescriptions for nPEP before sending patients to the SAFE program. The participants identified barriers encountered by their patients, ranging from emergency department providers inconsistently offering prescriptions for the correct medication, to difficulty locating a local pharmacy stocking nPEP. The SAFEs also expressed concern that uninsured patients had to complete additional steps to access nPEP, while feeling overwhelmed by the immediacy of their assaults. Several participants raised concern that patients' emotional distress and fear of acquiring HIV may impede their ability to comprehend information and access nPEP. Participants also noted that the 28-day nPEP regimen might be a daily reminder for patients of the sexual assault. The SAFEs identified multiple strategies for discussing HIV and nPEP with these patients. Implications of the SAFE's role in reducing barriers are discussed.

Abstract
There is a lack of data on pre-exposure prophylaxis (PrEP) effectiveness in Spain. We described the awareness of and willingness to use PrEP and examined potential barriers and facilitators to their use among men who have sex with men recruited either online or in voluntary HIV testing centers in Spain. Nearly a third of men (28.7 %) were aware of PrEP and 57.6 % said they would be willing to use it if available, 16.6 % saying they would be unwilling to use PrEP and 25.8 % not being sure. Men who had heard of PrEP were more forceful in their opinions on willingness to use PrEP (willing/not willing: 29.8 %/32.6 % vs. don't know: 21.8 %). The greatest consensus regarding more acceptable PrEP attributes was in the mode of delivery and its cost. Doctors (91 %) or pharmacists (85.3 %) were the preferred providers. The results confirm the need to inform and educate on PrEP and define implementation strategies.

Abstract
INTRODUCTION Few results from programmes based on combination prevention methods are available. We propose to analyse the degree of protection provided by postexposure prophylaxis (PEP) for consensual sexual activity at healthcare clinics, its compensatory effects on sexual behaviour; and the effectiveness of combination prevention methods and pre-exposure prophylaxis (PrEP), compared with exclusively using traditional methods. METHODS AND ANALYSIS A total of 3200 individuals aged 16 years or older presenting for PEP at 5 sexually transmitted disease (STD)/HIV clinics in 3 regions of Brazil will be allocated to one of two groups: the PEP group-individuals who come to the clinic within 72 h after a sexual exposure and start PEP; and the non-PEP group-individuals who come after 72 h but within 30 days of exposure and do not start PEP. Clinical follow-up will be conducted initially for 6 months and comprise educational interventions based on information and counselling for using prevention methods, including PrEP. In the second study phase, individuals who remain HIV negative will be regrouped according to the reported use of prevention methods and observed for 18 months: only traditional methods; combined methods; and PrEP. Effectiveness will be analysed according to the incidence of HIV, syphilis and hepatitis B and C and protected sexual behaviour. A structured questionnaire will be administered to participants at baseline and every 6 months thereafter. Qualitative methods will be employed to provide a comprehensive understanding of PEP-seeking behaviour, preventive choices and exposure to HIV. ETHICS AND DISSEMINATION This study will be conducted in accordance with the resolution of the School of Medicine Research Ethics Commission of Universidade de São Paulo (protocol no. 251/14). The databases will be available for specific studies, after management committee approval. Findings will be presented to researchers, health managers and civil society members by means of newspapers, electronic media and scientific journals and meetings.

Abstract
In the United States, rates of HIV infection are highest among black men who have sex with men (BMSM). Pre-exposure prophylaxis (PrEP) is a highly effective form of HIV prevention, but the uptake of this strategy has been slow since FDA approval in 2012, and it is unknown whether information about PrEP is reaching BMSM. Four hundred and thirty-six BMSM in Atlanta, GA were surveyed from January 2012 (6 months prior to PrEP approval) to March 2014 (20 months after approval). Analyses revealed no association between date of survey assessment and awareness of PrEP (20.5% were aware of PrEP before approval and 23.4% were aware after approval; OR=0.99 [0.98-1.02], p=0.952). In a multivariate model, BMSM unaware of PrEP reported lower rates of HIV testing knowledge, fewer experiences with HIV testing, and higher rates of transactional sex than BMSM who were aware of PrEP. Our findings suggest that there is limited understanding of PrEP and that there is considerable groundwork that needs to be achieved in order to reap the full benefits of PrEP. The current findings call attention to the need to both prioritize and better understand how to strengthen the bridge between medical advances and community uptake.

Abstract
Oral pre-exposure prophylaxis (PrEP) can reduce HIV incidence among at-risk persons. However, for PrEP to have an impact in decreasing HIV incidence, clinicians will need to be willing to prescribe PrEP. HIV specialists are experienced in using antiretroviral medications, and could readily provide PrEP, but may not care for HIV-uninfected patients. Six focus groups with 39 Boston area HIV care providers were conducted (May-June 2012) to assess perceived barriers and facilitators to prescribing PrEP. Participants articulated logistical and theoretical barriers, such as concerns about PrEP effectiveness in real-world settings, potential unintended consequences (e.g., risk disinhibition and medication toxicity), and a belief that PrEP provision would be more feasible in primary care clinics. They identified several facilitators to prescribing PrEP, including patient motivation and normative guidelines. Overall, participants reported limited prescribing intentions. Without interventions to address HIV providers' concerns, implementation of PrEP in HIV clinics may be limited.

Abstract
OBJECTIVES We sought to assess the prevalence and correlates of seroadaptive behaviours (i.e., sexual history incorporating some unprotected anal intercourse (UAI)) and conventional risk reduction behaviours (i.e., consistent condom use or no anal intercourse) among men who have sex with men (MSM) in San Francisco in 2011. We compared the prevalence of seroadaptive behaviours between serial cross-sectional surveys from 2004, 2008 and 2011. METHODS We analysed data from the 2011 wave of the National HIV Behavioral Surveillance system in San Francisco. We categorised men's self-reported sexual behaviour history in the past 6 months into a schema of seroadaptive behaviours and conventional risk reduction behaviours. We compared the prevalence of behaviour categories by self-reported HIV serostatus, HIV testing history, awareness of pre-exposure HIV prophylaxis (PrEP) and diagnosis of a sexually transmitted infection (STI). RESULTS Seroadaptive behaviours remained common in San Francisco MSM, with a 2011 prevalence of 46.6%, up from 35.9% in 2004. Consistent condom use or no anal intercourse was more common than seroadaptive behaviours in HIV-negative MSM, men who had not heard of PrEP and men without an STI diagnosis. Seroadaptive behaviours increased from 2004 to 2011. CONCLUSIONS HIV seroadaptive behaviours remain common in San Francisco MSM, have increased in the last decade and are practiced differently by MSM with different sexual health knowledge and outcomes. Public health researchers and officials should continue to document the prevalence, intentionality, efficacy and safety of seroadaptive behaviours among diverse communities of MSM.

Abstract
Antiretroviral pre-exposure prophylaxis (PrEP) has received increasing recognition as a viable prescription-based intervention for people at risk for HIV acquisition. However, little is known about racial biases affecting healthcare providers' willingness to prescribe PrEP. This investigation sought to explore medical students' stereotypes about sexual risk compensation among Black versus White men who have sex with men seeking PrEP, and the impact of such stereotypes on willingness to prescribe PrEP. An online survey presented participants (n = 102) with a clinical vignette of a PrEP-seeking, HIV-negative man with an HIV-positive male partner. Patient race was systematically manipulated. Participants reported predictions about patient sexual risk compensation, willingness to prescribe PrEP, and other clinical judgments. Bootstrapping analyses revealed that the Black patient was rated as more likely than the White patient to engage in increased unprotected sex if prescribed PrEP, which, in turn, was associated with reduced willingness to prescribe PrEP to the patient.
