Abstract
Considerable research has examined how involvement in gay-affiliated communities is associated with sexual health behaviours in sexual minority men (i.e., gay, bisexual, and other men who have sex with men), yet findings in this domain are often contradictory and inconclusive. This systematic review aimed to (a) synthesise the related empirical literature, and (b) identify potential factors driving inconsistent findings. Peer-reviewed publications were included if they contained quantitative data and at least one measure of the statistical association between gay community involvement and sexual health behaviour. The search strategy was implemented in six databases and returned 6,409 articles, of which 86 met the inclusion criteria. There was considerable heterogeneity in how gay community involvement was assessed across studies. Although gay community involvement was consistently associated with greater engagement in protective behaviours across studies, the association between gay community involvement and risk behaviours appeared to depend on how gay community involvement was conceptualised and measured (e.g., nightlife involvement vs. political activism). Findings emphasise a need for studies that employ validated measures that reflect the multidimensional nature of gay community involvement, as well as research designs better suited to address the causal effects of community involvement on HIV/STI transmission and prevention.

Abstract
Background PrEP uptake among Black and Latino gay, bisexual, and other men who have sex with men (GBM) remains low in the United States. The design and implementation of PrEP delivery programs that incorporate the preferences of Black and Latino GBM may overcome barriers to uptake. We aimed to identify preferences for PrEP care among high-priority GBM in the U.S. with a large discrete choice experiment. Methods We conducted two discreet choice experiments (DCE) to elicit care preferences for (1) Starting PrEP and (2) Continuing PrEP care among GBM clinically indicated for PrEP. The DCE web-based survey was nested in a longitudinal cohort study of GBM in the U.S., implemented with video and audio directions among 16-49 year-old participants, not using PrEP, and verified to be HIV-negative. All participants were presented with 16 choice sets, with choices determined by BLGBM and PrEP implementation stakeholders. We calculated overall utility scores and relative importance and used latent class analyses (LCA) to identify classes within the Starting and Continuing PrEP DCE. Multivariable analysis was performed to identify factors associated with class membership. Findings Among 1514 participants, mean age was 32 years; 46·5% identified as Latino, 21·4% Black, and 25·2 White; 37·5% had an income less than USD $20,000. Two latent classes were identified for Starting PrEP: Class 1 (n=431 [28·5%]) was driven by preference for more traditional in-person care, and Class 2 (n=1083 [71·5%]) preferred flexible care options and on-demand PrEP. In a multivariable model, having a sexual health doctor (adjusted OR 0·7, CI 0·5, 0·9), having a primary care provider (OR 0·7,CI 0·5, 0·9, p= 0·023), and concerns over PrEP side effects (OR 1·1, CI 1·0,1·2, p= 0·003) were all associated with class membership. Interpretation The different preferences identified for PrEP care indicate the need for diverse care and formulation choices to improve PrEP uptake and persistence. Addressing these preferences and understanding the factors that shape them can inform the implementation of programs that increase PrEP uptake.

Abstract
INTRODUCTION End-user perspectives are vital to the design of new biomedical HIV prevention products. Conjoint analysis can support the integration of end-user perspectives by examining their preferences of potential pre-exposure prophylaxis (PrEP) products. The Microbicides Trial Network (MTN) 035 protocol examined three placebo rectal dosage forms (insert, enema and suppository) that could deliver PrEP prior to receptive anal sex (RAS). METHODS Between April 2019 and July 2020, we enrolled 217 HIV-negative, cisgender men who have sex with men (MSM; n = 172; 79.3%) and transgender people (n = 47; 20.7%) ages 18-35 into a randomized cross-over trial across Malawi, Peru, South Africa, Thailand and the United States. Participants used each product prior to RAS over 4-week periods. Participants completed a conjoint experiment where they selected between random profiles using seven features (dosage form, timing of use before sex, side effects, duration of protection, effectiveness, frequency of use and need for a prescription). RESULTS Effectiveness was the strongest determinant of choice (30.4%), followed by modality (18.0%), potential side effects (17.2%), frequency of use (10.8%), duration of protection (10.4%), timing of use before sex (7.4%) and need for a prescription (5.9%). Relative utility scores indicated that the most desirable combination of attributes was a product with 95% efficacy, used 30 minutes before sex, offering a 3- to 5-day protection window, used weekly, having no side effects, in the form of an enema and available over-the-counter. CONCLUSIONS Choice in next-generation PrEP products is highly desired by MSM and transgender people, as no one-size-fits-all approach satisfies all the preferences. MTN-035 participants weighed product features differently, recognizing the need for diverse, behaviourally congruent biomedical options that fit the needs of intended end-users.

Abstract
INTRODUCTION Current implementation efforts have failed to achieve equitable HIV pre-exposure prophylaxis (PrEP) provision for transgender and gender-diverse (trans) populations. We conducted a choice-based conjoint analysis to measure preferences for key attributes of hypothetical PrEP delivery programmes among a diverse online sample predominantly comprised of transmasculine and nonbinary individuals in the United States. METHODS Between April 2022 and June 2022, a national online survey with an embedded conjoint analysis experiment was conducted among 304 trans individuals aged ≥18 years in the United States to assess five PrEP programme attributes: out-of-pocket cost; dispensing venue; frequency of visits for PrEP-related care; travel time to PrEP provider; and ability to bundle PrEP-related care with gender-affirming hormone therapy services. Participants responded to five questions, each of which presented two PrEP programme scenarios and one opt-out option per question and selected their preferred programme in each question. We used hierarchical Bayes estimation and multinomial logistic regression to measure part-worth utility scores for the total sample and by respondents' PrEP status. RESULTS The median age was 24 years (range 18-56); 75% were assigned female sex at birth; 54% identified as transmasculine; 32% as nonbinary; 14% as transfeminine. Out-of-pocket cost had the highest attribute importance score (44.3%), followed by the ability to bundle with gender-affirming hormone therapy services (18.7%). Minimal cost-sharing ($0 out-of-pocket cost) most positively influenced the attribute importance of cost (average conjoint part-worth utility coefficient of 2.5 [95% CI 2.4-2.6]). PrEP-experienced respondents preferred PrEP delivery in primary care settings (relative utility score 4.7); however, PrEP-naïve respondents preferred pharmacies (relative utility score 5.1). CONCLUSIONS Participants preferred programmes that offered PrEP services without cost-sharing and bundled with gender-affirming hormone therapy services. Bolstering federal regulations to cover PrEP services and prioritizing programmes to expand low-barrier PrEP provision are critical to achieving equitable PrEP provision. Community-engaged implementation research conducted by and in close collaboration with trans community stakeholders and researchers are needed to streamline the design of patient-centred PrEP programmes and develop implementation strategies that are salient to the diverse sexual health needs of trans patients.

Abstract
BACKGROUND Rectal microbicides (RM) are biomedical HIV prevention products that aim to prevent or reduce the transmission of HIV and other sexually transmitted infections (STIs). RM modalities may be beneficial for populations who have complex lifestyles, difficulties adhering to pre-exposure prophylaxis (PrEP) regimens, and/or have limited access to care. MTN-035 (DESIRE; Developing and Evaluating Short-Acting Innovations for Rectal Use), a randomized crossover trial, aimed to evaluate the safety and acceptability of, and adherence to, three placebo RM modalities (douche, insert, and suppository) prior to receptive anal intercourse. METHODS We conducted latent trajectory analysis to identify clusters of individuals who shared similar trajectories in acceptability and adherence for each product (douche, insert, and suppository) over time. We analyzed weekly short messaging service (SMS) use reports for each modality as reported by enrolled sexual and gender minority (SGM) participants. RESULTS Two trajectories for each product were identified: a "protocol compliant" trajectory (i.e., at least one product use occasion per week) and "high use" trajectory (i.e., more than three product use occasions per week). Participants with high use were more likely to lack access to PrEP and have higher intentions to utilize RM modalities compared to those who were protocol compliant. CONCLUSIONS This study highlighted high adherence to RM modalities among SGM. As research into viable HIV prevention modalities continues to evolve, tailored intervention strategies are needed to support the uptake of and adherence to alternative prevention modalities that are behaviorally congruent with targeted users.

Abstract
PURPOSE OF REVIEW Ending the HIV epidemic will require the development of additional effective immune-mediated and nonimmune-mediated means of HIV prevention. Evaluating novel interventions requires large, controlled trials demonstrating efficacy. Recent advances in the field of HIV prevention necessitate new approaches to efficacy trial design. RECENT FINDINGS Three classes of efficacy trial designs are possible: standard of prevention-controlled trials, active-controlled trials, and active-controlled trials augmented with external control data. Recent experience with these approaches provides lessons on considerations around and success of the designs. Additional experience and development is needed for the augmented active-controlled trial design. SUMMARY Efficacy trials of new HIV prevention interventions are feasible but require careful consideration, given the complexity and dynamic state of the prevention field. While standard of prevention-controlled efficacy trials are reasonable approaches for HIV vaccine and monoclonal antibody efficacy trials, trials of new antiretroviral agents may require active-controlled designs.

Abstract
Fears of relationship dissolution and the inability to bear healthy children remain barriers to HIV testing in sub-Saharan Africa. Pre-exposure prophylaxis (PrEP) carries both clinical and symbolic benefits that counter these fears. We conducted a pilot messaging intervention through Uganda's assisted partner notification (APN) program, where providers assist HIV-positive index clients in notifying sexual partners and encourage testing. We randomized providers at three clinics to implement phone scripts over two months with (1) gain-framed or (2) loss-framed information about PrEP and childbearing; or (3) usual care. In 23 in-depth interviews with providers, index clients, and partners, five major themes emerged on intervention acceptability and feasibility: (1) value of PrEP and childbearing messaging in APN; (2) value of this messaging coming earlier in APN; (3) overall preference for gain-framed messages; (4) need to tailor timing of messaging; and (5) need for messaging outside of APN. Register data (109 index clients, 145 partners) indicated most index clients (95%) wanted their potential conception partners informed about PrEP. Preliminary trends suggest the intervention sites outperformed usual care in testing rates among potential conception partners. Messaging that highlights PrEP and safe childbearing may be a promising new communication strategy to promote HIV testing.

Abstract
Prevalence of human immunodeficiency virus (HIV) is higher in transgender populations. Pre-exposure prophylaxis (PrEP) intervention is successful in reducing HIV acquisition. We aimed to investigate the adherence to oral PrEP by HIV-negative transgender women (TW). We followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA Statement. We searched in WoS, OVID, Scopus, MEDLINE, and the Cochrane Central Register of Controlled Trials databases. Participation and adherence to the intervention were low for TW compared to cisgender men who have sex with men (cMSM), and it was measured mostly by self-report (72.7%) or tenofovir-diphosphate/emtricitabine triphosphate dried blood spot (45.5%). Awareness should increase and the effect of oral PrEP on gender-affirming hormone therapy should be explained to TW at the beginning of the trials. One limitation is that our sample size was dominated by two Thai studies with TW sex workers. Future studies should evaluate adherence to new PrEP modalities.

Abstract
Despite evidence that pre-exposure prophylaxis (PrEP) reduces HIV risk, initiation and adherence remain low among vulnerable communities. Motivational interviewing (MI) can improve HIV prevention behaviors. However, limited research identifies how MI impacts PrEP uptake and adherence. This scoping review examines essential components of MI-based interventions that aimed to improve PrEP use, including the number and duration of sessions, counselor characteristics, and interview content. We searched four databases, PubMed, CINAHL Plus, Embase, and Web of Science, and reviewed 379 articles. Studies were considered if they (a) were published between 2012 and 2023, (b) used MI independently or part of a multi-component intervention strategy, and (c) focused on improving PrEP initiation or adherence. Seven articles met inclusion criteria. Regarding intervention components, the number of MI sessions varied and duration ranged between 15 and 60 min. MI counselors varied in credentialing and demographic characteristics. MI content included PrEP education, identifying initiation and adherence barriers, and strategizing ways to overcome barriers. MI is an important component of interventions that aim to improve PrEP initiation and adherence. However, the variability and limited details across studies hinder our ability to assess MI efficacy on PrEP initiation and adherence or replicate these approaches in future interventions.

Preferences for long-acting pre-exposure prophylaxis among gay, bisexual and other men who have sex with men in Taiwan: findings from the 2021 HEART Survey. J Int AIDS Soc 2023; 26:e26163.

Abstract
INTRODUCTION While various antiretrovirals have been studied as potential candidates for long-acting pre-exposure prophylaxis (PrEP), the bimonthly injectable cabotegravir-the first long-acting form of PrEP-was approved in 2021. Event-driven (ED) PrEP has been the most prevalent dosing regimen among gay, bisexual and other men who have sex with men (GBMSM) in Taiwan, providing a unique setting to observe the preferences for long-acting PrEP in a community where the daily regimen is not the mainstream method. This study aimed to determine the preferences for the different forms and dosing intervals of long-acting PrEP that are currently in the development pipeline. METHODS We conducted a survey in 2021 by convenience sampling the users of social networking applications for GBMSM in Taiwan. Our survey included questions on sexual behaviours, current PrEP regimens and the preferences for potential candidates of long-acting PrEP, such as implants, intramuscular and subcutaneous injections. We compared the Likert-scale preference ratings for potential long-acting options, and conducted logistic regression analysis to examine the factors associated with a preference for bimonthly intramuscular injections (2M IM) over ED and daily PrEP regimens, respectively. RESULTS A total of 1728 responses were eligible for analysis. Three percent of respondents (n = 52) were daily PrEP users; 11.5% (n = 198) were ED PrEP users. When not considering cost, current PrEP users-regardless of their original dosing regimen-were most likely to express preferences for monthly oral PrEP, followed by a 6-month subcutaneous injectable (6M SC) and 2M IM. However, among non-current PrEP users, monthly oral PrEP was the most preferred form, followed by ED, daily oral and 6M SC injectable. Multivariable logistic regression revealed that current daily users, those willing to take PrEP in the next 6 months and those with more sex partners in the last 12 months had a significant correlation with preferences for the 2M IM injectable over the ED PrEP. CONCLUSIONS The monthly oral form was the most preferable long-acting PrEP among GBMSM in Taiwan. Current daily PrEP users preferred the 2M IM injectable over the ED PrEP, which made the 2M IM injectable a potential alternative. Further studies should focus on how the cost and delivery affect PrEP preferences and their actual uptake.

Transfus Med Rev 2023; 37:150754. [PMID: 37741792 DOI: 10.1016/j.tmrv.2023.150754] [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: 07/18/2023] [Revised: 08/14/2023] [Accepted: 08/16/2023] [Indexed: 09/25/2023]
Abstract
Pre- and postexposure prophylaxis for human immunodeficiency virus (HIV) are key to reducing the transmission of this virus. Furthermore, low-toxicity, long-acting formulations provide additional clinical benefits, in particular easier adherence to treatment and prevention. However, breakthrough HIV infections can occur despite the use of pre-exposure prophylaxis (PrEP), mainly due to suboptimal adherence or multi-drug resistant HIV strains. Albeit rare, PrEP breakthrough infections have also been reported in fully adherent patients. Should such breakthrough infection occur in an eligible blood donor, PrEP might suppress viremia and delay antibody seroconversion, thereby masking the infection and increasing the risk of transfusion transmission. This possibility has raised concerns in the blood transfusion community but remains little documented. Therefore, a literature search was performed to assess the state of knowledge on the risk of PrEP breakthrough infection, with a particular focus on the risk of HIV entering the blood supply. Evidently, PrEP breakthrough infections are rare, although the risk is not zero. Moreover, a fraction of individuals - including blood donors - do not disclose PrEP use according to various surveys and measurements of HIV PrEP analytes. Additionally, viremia and seroconversion may remain undetectable or close to the limit of detection for a long time after cessation of PrEP, particularly with long-acting antiretrovirals. Therefore, current recommendations to defer donors for at least 3 months after the last dose of oral PrEP or 2 years for long-acting PrEP appear justified, as they safeguard the blood supply and public trust toward the system. These recommendations help to safeguard blood safety and public trust in the blood supply.

Abstract
Efforts to develop a range of HIV prevention products that can serve as behaviorally congruent viable alternatives to consistent condom use and oral pre-exposure prophylaxis (PrEP) remain crucial. MTN-035 was a randomized crossover trial seeking to evaluate the safety, acceptability, and adherence to three placebo modalities (insert, suppository, enema) prior to receptive anal intercourse (RAI). If participants had no RAI in a week, they were asked to use their assigned product without sex. We hypothesized that the modalities would be acceptable and safe for use prior to RAI, and that participants would report high adherence given their behavioral congruence with cleansing practices (e.g., douches and/or enemas) and their existing use to deliver medications (e.g., suppositories; fast-dissolving inserts) via the rectum. Participants (N = 217) were sexual and gender minorities enrolled in five different countries (Malawi, Peru, South Africa, Thailand, and the United States of America). Mean age was 24.9 years (range 18-35 years). 204 adverse events were reported by 98 participants (45.2%); 37 (18.1%) were deemed related to the study products. The proportion of participants reporting "high acceptability" was 72% (95%CI: 65% - 78%) for inserts, 66% (95%CI: 59% - 73%) for suppositories, and 73% (95%CI: 66% - 79%) for enemas. The proportion of participants reporting fully adherent per protocol (i.e., at least one use per week) was 75% (95%CI: 69% - 81%) for inserts, 74% (95%CI: 68% - 80%) for suppositories, and 83% (95%CI: 77% - 88%) for enemas. Participants fully adherent per RAI-act was similar among the three products: insert (n = 99; 58.9%), suppository (n = 101; 58.0%) and enema (n = 107; 58.8%). The efficacy and effectiveness of emerging HIV prevention drug depends on safe and acceptable delivery modalities that are easy to use consistently. Our findings demonstrate the safety and acceptability of, and adherence to, enemas, inserts, and suppositories as potential modalities through which to deliver a rectal microbicide.

Abstract
HIV pre-exposure prophylaxis (PrEP) use remains suboptimal among Black gay and bisexual men (GBM). Multilevel factors such as medication costs, intersectional stigma, patient-clinician communication, medical mistrust, side effect concerns, and low perceived HIV risk (PHR) are well-established PrEP initiation barriers for this group. Peer change agents (PCAs) are culturally congruent interventionists who can circumvent multilevel PrEP barriers among Black GBM. I led an intervention as a PrEP-using PCA to improve PHR and PrEP willingness among 69 Black GBM from 2019-2022 and conducted an autoethnography to better understand multilevel barriers and identify the personal/professional challenges of being an in-group HIV interventionist serving Black SMM. Findings provide novel perspectives regarding PrEP barriers, the role of cultural homophily in behavior change interventions, and how interpersonal dynamics can impact staff fatigue, protocol fidelity, and research participation. Recommendations to prepare and support culturally congruent research staff are also provided.

Abstract
This experiment tested mechanisms linking alcohol intoxication and analogue determinants of condomless anal intercourse (CAI) in a sample of 257 men who have sex with men (MSM). The two mechanisms tested were implicit approach biases toward CAI stimuli and executive working memory. Participants were randomized to 3 conditions (water control, placebo, or alcohol) and following beverage administration completed a working memory task, an Approach Avoidance Task of sexual vs. condom stimuli, and two video role-play vignettes of high-risk sexual scenarios. Sexual arousal and CAI intentions were assessed by self-report, and behavioral skills and risk exposure were derived from participants' role-play behavior. Estimation of four path models showed that the hypothesized mechanisms were supported for the CAI intention outcome, but the findings for the skills and risk exposure outcome were mixed. Implications for development and enhancement of HIV prevention interventions were discussed.

Abstract
After a decade of oral HIV pre-exposure prophylaxis (PrEP), the next generation of PrEP is being anticipated, including long-acting pills, injections, and implants. The unevenness of international PrEP implementation is increasingly recognised, with successful rollout in some settings and failure in others. There is a need to better understand conditions of PrEP implementation, and its localised (and sometimes unanticipated) effects. Implementation science explores how contexts and health systems shape the successful translation of health interventions. In this essay, we consider how PrEP is evolving and argue for an 'evidence-making' approach in relation to evidence and intervention translations. This approach emphasises how both interventions and their implementation contexts are co-constituted and evolve together. Unsettling the assumed universality of an intervention's effects and potential in relation to its implementation contexts helps to harness the localised possibilities for what PrEP might become. As the next generation of PrEP offers renewed promise, we must explore how PrEP is put to use and made to work in relation to its evolving situations. We urge implementation science to consider implementation processes as 'evidence-making events' in which evidence, intervention and context evolve together.

Abstract
Background Pre-exposure prophylaxis (PrEP) is a valuable tool in the response to the HIV epidemic, recommended for groups with a higher risk of HIV infection, such as men who have sex with men (MSM), particularly in the context of high-risk sexual behavior such as chemsex. Purpose This study aimed to analyze the prevalence and factors associated with the intention to use PrEP among MSM who engage in chemsex in Brazil and Portugal. Methods This was a cross-sectional study of a secondary dataset from a larger study conducted between January 2020 and May 2021 throughout Brazil and Portugal involving 1852 MSM who engage in chemsex. An initial descriptive analysis was performed to calculate the absolute and relative frequencies of independent variables related to the intention to use PrEP among MSM. A multivariate regression model was developed to identify factors independently associated with the intention to use PrEP. Results Although a high level of PrEP knowledge (85.75%) was observed among MSM who engage in chemsex, the prevalence of intention to use PrEP was only 59.07%. Five variables were associated with a higher prevalence of intention to use PrEP [engaging in double penetration - adjusted prevalence ratio (aPR): 1.56, 95% CI: 1.44-1.69; being assigned female sex at birth - aPR: 1.34, 95% CI: 1.12-1.61; cruising - aPR: 1.21, 95% CI: 1.06-1.38; not using condoms - aPR: 1.20, 95% CI: 1.05-1.36; and being an immigrant - aPR: 1.16; 95% CI: 1.07-1.25], while having knowledge of postexposure prophylaxis (aPR: 0.91; 95% CI: 0.84-0.98), having a casual sexual partner (aPR: 0.86 and 0.85; 95% CI: 0.74-0.99 and 0.74-0.98), and engaging in group sex (aPR: 0.81; 95% CI: 0.73-0.90) were associated with a lower intention to use PrEP. Conclusion The intention to use PrEP among MSM who engage in chemsex was high, and several factors were associated with this intention. Understanding the factors associated with the intention to use PrEP among MSM practicing chemsex is crucial for developing targeted interventions to increase PrEP uptake in this population. The results of this study suggest that tailored approaches are necessary to promote PrEP use in this population.

Abstract
Pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, yet PrEP delivery to women in periconception and pregnancy has lagged. We report qualitative research from a study evaluating PrEP use as part of safer conception care for 330 South African women. Fifty-two semi-structured interviews were conducted with 25 study participants to identify influences on PrEP adherence. Influences were: (1) changing proximity to male partners; (2) COVID-19 lockdown; (3) mobile lifestyle; (4) PrEP-related stigma; (5) disclosure of PrEP use; and (6) pregnancy and motherhood. Data also revealed important contextual information shaping adherence influences for women, including: (a) not living with partners, (b) partners as drivers of pregnancy intention, and (c) feeling at high risk for HIV. Disclosure of PrEP use, addressing stigma, strategies for traveling with pills, and counseling on prevention effective adherence are promising components of PrEP-inclusive HIV prevention interventions for South African women who are pregnant or planning pregnancy.

Abstract
HIV/AIDS mortality has been decreasing over the last decade. While promising, this decrease correlated directly with increased use of antiretroviral drugs. As a natural consequence of its high mutation rate, treatments provide selection pressure that promotes the natural selection of escape mutants. Individuals may acquire drug-naive strains, or those that have already mutated due to treatment. Even within a host, mutation affects HIV tropism, where initial infection begins with R5-tropic virus, but the clinical transition to AIDS correlates with mutations that lead to an X4-tropic switch. Furthermore, the high mutation rate of HIV has spelled failure for all attempts at an effective vaccine. Pre-exposure drugs are currently the most effective drug-based preventatives, but their effectiveness is also threatened by viral mutation. From attachment and entry to assembly and release, the steps in the replication cycle are also discussed to describe the drug mechanisms and mutations that arise due to those drugs. Revealing the patterns of HIV-1 mutations, their effects, and the coordinated attempt to understand and control them will lead to effective use of current preventative measures and treatment options, as well as the development of new ones.

Abstract
OBJECTIVE The authors sought to determine the efficacy of targeted naltrexone in sexual and gender minority men (SGM) who binge drink and have mild to moderate alcohol use disorder. METHODS In a double-blind placebo-controlled trial, a total of 120 SGM who binge drink and have mild to moderate alcohol use disorder were randomized in a 1:1 ratio to receive targeted oral naltrexone (50 mg) or placebo with weekly counseling for 12 weeks. The study's primary endpoints were binge-drinking intensity, defined as 1) number of drinks in the past 30 days; 2) any binge drinking in the past week; 3) number of binge-drinking days in the past week; and 4) number of drinking days in the past week. The study also measured changes in alcohol use with two alcohol biomarker measures: ethyl glucuronide in urine samples and phosphatidylethanol (PEth) in dried blood spot samples. RESULTS Ninety-three percent completed the trial, with 85% of weekly follow-up visits completed. In intention-to-treat analyses, naltrexone was associated with a significantly reduced reported number of binge-drinking days (incidence rate ratio [IRR]=0.74, 95% CI=0.56, 0.98; number needed to treat [NNT]=2), weeks with any binge drinking (IRR=0.83, 95% CI=0.72, 0.96; NNT=7.4), number of drinks per month (IRR=0.69, 95% CI=0.52, 0.91; NNT=5.7 for 10 drinks), and alcohol craving scores (coefficient=-9.25, 95% CI=-17.20, -1.31). In as-treated analyses among those who took their medication on average at least 2.5 days per week (the median frequency in the study), naltrexone reduced any binge drinking (IRR=0.84, 95% CI=0.71, 0.99), number of binge-drinking days (IRR=0.67, 95% CI=0.47, 0.96), and PEth concentrations (coefficient=-55.47, 95% CI=-110.75, -0.20). At 6 months posttreatment, naltrexone had sustained effects in number of drinks per month (IRR=0.69, 95% CI=0.50, 0.97), number of binge-drinking days (IRR=0.67, 95% CI=0.47, 0.95), and any binge drinking in the past week (IRR=0.79, 95% CI=0.63, 0.99). CONCLUSIONS Targeted naltrexone significantly reduced drinking outcomes among SGM with mild to moderate alcohol use disorder during treatment, with sustained effects at 6 months posttreatment. Naltrexone may be an important pharmacotherapy to address binge drinking in populations with mild to moderate alcohol use disorder.

BMC Infect Dis 2022; 22:737. [PMID: 36104676 PMCID: PMC9473463 DOI: 10.1186/s12879-022-07572-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 06/28/2022] [Indexed: 11/25/2022] Open
Abstract
Background Outbreaks of new HIV transmission among people who inject drugs (PWID) are a major public health concern. Oral daily PrEP, has been identified as a critical addition to the biomedical toolkit for this population. However, limited research on the acceptability of long-acting injectable PrEP has been conducted with this population. Methods We conducted a cross sectional multi-site survey with 1127 participants from May 2019–February 2020 to assess the acceptability of novel PrEP regimens. We computed bivariate and multivariable logistic regressions to evaluate correlates of the outcome variable: acceptability of 3-month injectable-PrEP. SAS v.9.4 was used to conduct statistical analysis. Results Limited knowledge of or use of PrEP, past or present, was evident within the sample. Injection drug use in the past six months was significantly associated with LA injectable PrEP acceptability, with the odds of acceptability being 1.885 (CI: 1.376, 2.582) times greater than those who did not inject drugs. After adjusting for confounders, injection drug use was significantly associated with the outcome, such that the odds of acceptability of LA injectable PrEP were 1.705 (CI: 1.198, 2.427) times greater among PWID compared to those who did not inject drugs (p < 0.03). The results demonstrate acceptability (38.2%) in a durable (3-month) injectable PrEP modality among participants who also identified as PWID. Conclusions PrEP promotion efforts among PWID to increase access to long-acting injectable PrEP are necessary. Through efforts to increase acceptance and regular use of long-acting injectable PrEP, public health strategies may be able to effectively lessen chances of future HIV outbreaks among PWID.

Abstract
OBJECTIVES HIV scholars and practitioners have worked to expand strategies for prevention among marginalised populations who are disproportionately impacted by the epidemic, such as racial minority men who have sex with men (MSM). Given this urgency, the objective of this study was to assess interest in biomedical prevention strategies. METHODS This exploratory and cross-sectional study investigated interest in four biomedical prevention tools-rectal douche, dissolvable implant, removable implant and injection-among a racially diverse sample of MSM from the Northeast Corridor region between Philadelphia and Trenton. Data were collected as part of screening for Connecting Latinos en Pareja, a couples-based HIV prevention intervention for Latino MSM and their partners. RESULTS A total of 381 individuals participated in the screener and provided information about their interest in bio tools. Approximately 26% of participants identified as black, 28% as white and 42% as 'other' or multiracial; 49% identified as Latino. Majority (54%) reported some form of child sexual abuse. Of the participants who reported being in a primary relationship (n=217), two-thirds reported unprotected anal sex within that relationship over the past 90 days (n=138, 64%) and approximately half (n=117, 54%) reported unprotected anal sex outside of the relationship in this period. Majority of participants reported interest in all bio tools assessed, including dissolvable implants (60%), removable implants (64%), rectal douching (79%) and injection (79%). Although interest in bio tools was broadly unassociated with demographics and sexual risk behaviours, analyses revealed significant associations between reports of child sexual abuse and interest in implant and injection methods. CONCLUSIONS The authors recommend investing in these prevention methods, particularly rectal douching and injection, as a means of preventing HIV among racial minority MSM. Given the interest in biomedical prevention tools, future studies should explore potential strategies for adherence.

Abstract
In a nationwide sample of Black women in the U.S., we assessed preferences for HIV preexposure prophylaxis (PrEP) products, including long-acting injectable (LAI) PrEP and once-daily oral PrEP. Among 315 respondents, 32.1% were aware of PrEP and 40.6% were interested in using it; interest increased to 62.2% if PrEP were provided for free. Oral PrEP was the preferred option (51.1%), followed by LAI PrEP (25.7%), vaginal gel (16.5%), and vaginal ring (6.7%). When examining oral and LAI PrEP alone, most (62.7%) preferred oral PrEP. LAI PrEP was more likely to be preferred among respondents with concerns about healthcare costs or PrEP-related stigma, and among those who reported inconsistent condom use and multiple sexual partners. Although most Black women preferred oral PrEP, LAI PrEP may be appealing to a subset with social and structural barriers to PrEP use, such as cost and stigma, and those at increased risk of HIV infection.

Abstract
The Information-Motivation-Behavioral Skills (IMB) Model has been used to understand adherence to medications and intentions to uptake pre-exposure prophylaxis (PrEP) to prevent HIV infection. In the current study, the IMB Model was used to understand factors that predict adherence to PrEP among a community-based cohort of 204 Black men who have sex with men (MSM) and transgender women (TGW) using structural equation modeling. PrEP motivation was directly associated with PrEP behavioral skills (β = 0.320, p = 0.009), and PrEP behavioral skills were directly associated with PrEP adherence (β = 0.416, p = 0.001). PrEP knowledge and PrEP motivation were not associated with PrEP adherence, directly or indirectly. The analysis identified intervenable factors that predicted PrEP adherence. Screening for motivation and behavioral skills could be used to identify where additional support to improve PrEP adherence is needed, or whether to offer alternative PrEP modalities or delivery strategies.

Abstract
Pre-exposure prophylaxis is an effective women-controlled HIV prevention strategy but women experiencing intimate partner violencefear partners' interference and subsequent violence could limit its utility. This study explores provider perceptions of safety planning strategies to prevent escalating violence, mitigate partner interference, and promote daily oral PrEP adherence. We conducted interviews (N = 36) with healthcare providers (n = 18) and IPV service providers (n = 18) in Baltimore and New Haven. Using the Contextualized Assessment for Strategic Safety Planning model we organized data into two categories: the appraisal process and strategic safety planning. Themes revealed during the appraisal process, providers conduct routine IPV screening, facilitate HIV risk perception, and offer PrEP. Strategic safety planning utilizes concealment tactics, informal sources of support, role playing and cover stories. Future interventions to enhance PrEP services among women exposed to IPV should implement safety planning strategies, integrate PrEP care with IPV services, and employ novel PrEP modalities to maximize effectiveness.

Abstract
This study describes the acceptability of a rectal microbicide gel formulation using dapivirine (DPV) among men and women from two countries (United States and Thailand) participating in the Microbicide Trials Network-026 trial. We evaluated participants' acceptability of a rectal DPV/placebo gel as part of a Phase I trial (N = 26; 18 male, 8 female). Participants reported favorable acceptability of the study gel, with most participants reporting that they liked the gel the same (n = 14; 53.8%) or more (n = 11; 42.4%) than when they started the trial. Over half of participants noted that they would prefer the gel over condoms (n = 13; 50%) or that they liked condoms and the gel equally (n = 8; 30.8%). Side effects across products included leakage (n = 8; 30.8%), diarrhea (n = 4; 15.4%), or soiling (n = 1; 3.8%). The high acceptability of a rectal gel underscores its promise as a short-acting biomedical prevention, warranting future research for HIV prevention.Trial Registration: NCT03239483.

Abstract
Long-acting injectable (LAI) modalities have been developed for ART and PrEP. Women face unique barriers to LAI use yet little research has examined women's perceptions of potential LAI HIV therapy candidates. We conducted 89 in-depth interviews at six Women's Interagency HIV Study (WIHS) sites with women living with HIV (n = 59) and HIV-negative women (n = 30) from 2017 to 2018. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Participants identified specific sub-populations who could most benefit from LAI over daily pills: (1) young people; (2) women with childcare responsibilities; (3) people with adherence-related psychological distress; (4) individuals with multiple sex partners; and (5) people facing structural insecurities such as homelessness. Women are underserved by current HIV care options and their perspectives are imperative to ensure a successful scale-up of LAI PrEP and LAI ART that prioritizes equitable access and benefit for all individuals.

Abstract
Late presentation for care is a major impediment to the prevention and effective treatment of HIV infection. Older individuals are at increased risk of late presentation, represent a growing proportion of people with late presentation, and might require interventions tailored to their age group. We provide a summary of the literature published globally between 2016-21 (reporting data from 1984-2018) and quantify the association of age with delayed presentation. Using the most common definitions of late presentation and older age from these earlier studies, we update this work with data from the International Epidemiology Databases to Evaluate AIDS (IeDEA) consortium, focusing on data from 2000-19, encompassing four continents. Finally, we consider how late presentation among older individuals might be more effectively addressed as electronic medical records become widely adopted.

Background Young Black women between the ages of 18 and 24 years are disproportionately impacted by HIV, yet they have a low self-perception of HIV risk and limited exposure to prevention strategies. Pre-exposure prophylaxis (PrEP) is a safe and effective biomedical HIV prevention strategy for those at risk for HIV infection, but uptake has been slow among cisgender women. Family planning clinics are a primary source of health care access for young women, providing an ideal opportunity to integrate PrEP information and care into existing clinic practices. Objective The aim of this study was to use a multistage, community-engaged process to develop a mobile health app and to evaluate the feasibility and acceptability of the app. Methods Using user-centered design, the In the Loop app was developed in collaboration with a community advisory board of young Black women. This study employed a multistage design, which included community-engaged app development, user testing, and evaluation of the app’s feasibility and acceptability. A pre- and postdesign was used to assess the impact of the app on PrEP knowledge immediately after app use. Descriptive statistics (eg, mean, SD, and percentage values) were used to describe the sample, and Wilcoxon matched-pairs signed-ranks test was used to detect changes in PrEP knowledge before and immediately after using the app. Results A total of 50 sexually active, young Black women, aged 18-24 (mean 21, SD 1.9) years, were enrolled in this study. Analysis comparing scores before and immediately after use of the app revealed a significant increase in PrEP content knowledge scores on a 7-item true or false scale (z=–6.04, P<.001). Overall, participants considered the In the Loop app feasible and acceptable to use while waiting for a family planning visit. The majority of participants (n=46, 92%) agreed that they would recommend In the Loop to friends to learn more about PrEP. Participants rated the overall quality of the app 4.3 on a 1-5 scale (1=very poor and 5=very good). Of 50 participants, 40 (80%) agreed that the app was easy to use, and 48 (96%) agreed that they found the information in the app easy to understand. Finally, 40 (80%) agreed that they had enjoyed using the app while waiting for their family planning visit. Conclusions Our findings suggest that young Black women waiting for family planning visits found the In the Loop app to be feasible and acceptable. This study demonstrates the value of engaging young Black women in the app design process. As family planning clinics are a primary source of health care access for young women, they provide an ideal setting to integrate PrEP information and care into existing clinic practices. Next steps in the development of the In the Loop app include implementing user-suggested improvements and conducting efficacy testing in a randomized controlled trial to determine the app’s impact on PrEP uptake.

Abstract
Inequities in HIV pre-exposure prophylaxis (PrEP) use persist in the United States. Although scientific advancement in delivery options and social acceptance of PrEP has occurred in the past decade, gaps remain in ensuring that this sexual health program is available to all. Components of what a national PrEP program for all would look like are discussed.

Abstract
HIV/AIDS disproportionately burdens African immigrants in the United States. Oral pre-exposure prophylaxis (PrEP) is an effective prevention tool for people at high HIV risk, yet uptake is low among racial and ethnic minorities-particularly immigrants. This study explores the awareness, perception, and willingness to use PrEP among Ghanaian immigrants in the United States. WhatsApp, a social media platform, was used to recruit and conduct semi-structured oral interviews with 40 Ghanaian immigrants in March 2020. Interview questions explored awareness of PrEP (whether the participants knew or had knowledge of PrEP before the study), perceptions of PrEP and PrEP users, and willingness to use PrEP. Interviews were audiorecorded, and transcribed. We used NVivo-12 Plus to analyze transcripts for emergent themes. Our sample consisted of Ghanaian adult immigrants (N = 40, 57% male, 71% college educated, age = 32.8 ± 5.7 years, 68% had lived in the United States between 1 and 10 years) residing in 12 US cities. Four major themes emerged: (1) low awareness of PrEP; (2) positive perception of PrEP for HIV prevention; (3) divergent views on PrEP users; and (4) mixed views on willingness to use PrEP. This study presents formative qualitative work, which suggests that Ghanaian immigrants, despite having low awareness of PrEP, may be willing to use PrEP. A key study implication was that stigma reduction interventions might facilitate PrEP scale-up in this population.

Pre-exposure Prophylaxis Uptake, Adherence, and Persistence: A Narrative Review of Interventions in the U.S. Am J Prev Med 2021; 61:S73-S86. [PMID: 34686294 DOI: 10.1016/j.amepre.2021.04.036] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/21/2021] [Accepted: 04/26/2021] [Indexed: 12/12/2022]
Abstract
Since 2012, HIV pre-exposure prophylaxis (PrEP) has been available to prevent HIV transmission; yet, uptake, adherence, and persistence to PrEP have been suboptimal. This narrative review examines the latest interventions and programs to improve all 3 stages of PrEP adherence and reviews ongoing studies to promote effective PrEP use. From 2017 to 2020, a total of 20 studies analyzed different individual- and structural-level approaches to increase PrEP adherence, including behavior change interventions, technology-based interventions (e.g., short message service messages and mobile applications), and alternate delivery strategies (e.g., pharmacy-based PrEP, integration with other services, and home delivery). Most published interventions involved men who have sex with men, although 3 assessed women (2 transgender, 1 cisgender). Randomized, controlled data support 3 behavioral change interventions and 1 technology-based intervention. Alternate delivery strategies seem promising, although more robust study designs are generally needed. In addition, data on the alignment of ongoing HIV risk and PrEP persistence (i.e., prevention-effective adherence) were limited. The authors also identified 20 ongoing studies that are promoting PrEP adherence. Future work should be inclusive of all at-risk groups in the U.S., including African American and Latinx heterosexual populations and people who inject drugs. Proven and promising approaches may work well in combination and may also need to be adapted with the introduction of long-acting pre-exposure prophylaxis formulations. Collectively, this body of work indicates considerable progress toward understanding the role PrEP adherence will play in Ending the HIV Epidemic in the U.S. that will be bolstered by the outcomes of ongoing trials.

Abstract
In 2012, the U.S. FDA approved the first drug for use as HIV Pre-Exposure Prophylaxis (PrEP), which is nearly 99% effective when taken as prescribed. Although the manifest function of PrEP is to prevent HIV infection in the event of exposure, the drug has also had a significant impact on various facets of sexuality. In this review, we focus on research that emerged in the near decade since PrEP's approval, with a specific focus on the ways in which different elements of sex and sexuality have been impacted by gay, bisexual, and other men who have sex with men (GBMSM), cisgender women, and transgender individuals. We highlight evidence showing how PrEP has enhanced sexual self-esteem, improved sexual pleasure, reduced sexual anxiety, and has increased sexual agency for those taking it. For many, PrEP also serves as a gateway to improve routine health and increase sexual health-care utilization. Additionally, we review the question of whether PrEP is associated with increased sexual risk taking (i.e. risk compensation), and note that, although some data are mixed, PrEP is not intended as an intervention to reduce condomless anal sex or STIs: it aims to prevent HIV. Finally, our review highlights that, although the volume of research on PrEP among GBMSM is robust, it is underdeveloped for cisgender women and transgender populations and insufficient for inclusion in such a review for cisgender heterosexual men was. PrEP research with these populations is an important direction for future research. Finally, from 2012 to 2019, a single PrEP formulation and delivery method was FDA approved (oral emtricitabine/tenofovir disoproxil fumarate). As additional drug formulations (ie.g., emtricitabine/tenofovir alafenamide) and delivery methods (e.g., microbiocides, vaginal ring, injectable) come to market, it will be important to examine how these, too, impact the spectrum of sexuality.

Abstract
BACKGROUND Volatility in sexual contact rates has been recognized as an important factor influencing HIV transmission dynamics. One-time partnerships may be particularly important given the potential to quickly accumulate large number of contacts. Yet, empirical data documenting individual variation in contact rates remain rare. This study provides much needed data on temporal variation in one-time partners to better understand behavioral dynamics and improve the accuracy of transmission models. METHODS Data for this study were obtained from a longitudinal cohort study of young men who have sex with men and transgender women in Chicago. Participants provided sexual network data every 6 months for 2 years. A series of random effects models examined variation in one-time partnership rates and disaggregated within and between associations of exposure variables. Exposure variables included prior number of one-time partners, number of casual partners, and having a main partner. RESULTS Results indicated substantial between-person and within-person variation in one-time partners. Casual partnerships were positively associated and main partnerships negatively associated with one-time partnership rates. There remained a small positive association between prior one-time partnerships and the current number of one-time partnerships. CONCLUSIONS Despite the preponderance of a low number of one-time partners, substantial variation in one-time partnership rates exists among young men who have sex with men and transgender women. Accordingly, focusing on high contact rate individuals alone may be insufficient to identify periods of highest risk. Future studies should use these estimates to more accurately model how volatility impacts HIV transmission and better understand how this variation influences intervention effectiveness.

Abstract
The availability of multiple pre-exposure prophylaxis (PrEP) regimens creates a preference-sensitive choice for individuals weighing alternative HIV prevention strategies. Investigating factors that are associated with PrEP uptake and regimen choice are key to developing tools to support that decision. A cross-sectional survey was offered to 536 participants in a PrEP demonstration project for gay, bisexual, and other men who have sex with men across 3 cities in China, of which 412 completed surveys and were included in the analysis. We conducted bivariable analyses followed by multi-variable logistic regressions to examine factors associated with overall PrEP uptake and PrEP regimen choice. Among the 412 participants, 36.9% were daily PrEP users, 28.4% were event-driven users, and 34.7% were non-PrEP users. Higher levels of education, lower PrEP use stigma, and higher perceived benefits of PrEP were associated with greater PrEP uptake. More frequent sex, higher PrEP adherence self-efficacy, higher endorsement of the belief in elevated efficacy of daily over on-demand PrEP, and lower endorsement of a desire for a PrEP method that is only taken when needed led to greater odds of choosing the daily PrEP regimen. As multiple HIV prevention modalities become available, there is a greater need for a shared decision-making approach to support this preference-sensitive choice of HIV prevention method. Our findings suggest salient constructs to inform the development of shared decision-making tools to support regimen choice.

Abstract
Pre-exposure prophylaxis (PrEP) has the ability to curb HIV transmission among women if they are highly adherent (e.g. 6/7 weekly doses). In a recent PrEP demonstration project with 95 women who inject drugs (WWID) in Philadelphia, PA, USA, PrEP uptake was high but adherence was low. This qualitative study draws upon the Behavioral Model for Vulnerable Populations (BMVP) to describe how the context of 23 WWID's lives challenged PrEP adherence using narrative data from in-depth interviews. Content analysis suggests that women's need to organize their day around predisposing survival needs made it difficult to prioritize PrEP. Adherence was further challenged by dis-enabling structural forces such as entry into institutions that do not provide PrEP (e.g., drug treatment and correctional facilities) and medication diversion to illicit marketplaces. Overtime, women's perceived need for PrEP was dynamic: in periods they characterized as risky, women considered PrEP highly beneficial and described enhanced motivation to adhere. In periods of low perceived risk, women were less committed to continuing daily PrEP in the context of their competing survival needs. In sum, WWID faced challenges to PrEP adherence that correspond to all of the BMVP domains. To optimize PrEP for WWID, multi-level programs are needed that address the determinants that both increase HIV susceptibility and undermine adherence.

Abstract
Interest is growing in "smart" vaginal microbicides as a strategy to protect women from sexual transmission of human immunodeficiency virus (HIV). The concept is based on the development of products featuring low drug release in acidic media such as vaginal fluid but switch to a fast release profile when the medium becomes neutral or slightly alkaline. This mimics the surge in pH occurring in the vagina after sexual intercourse due to the seminal fluid. Semen is the main vehicle for HIV-1, and increasing antiretroviral drug levels in the vagina upon ejaculation may contribute to enhanced protection against viral sexual transmission. This work explores the use of different pharmaceutical-grade methacrylic acid-based polymers (EudragitⓇ RL, RS, L and S) for developing vaginal films allowing the pH-dependant release of the antiretroviral drug tenofovir (TFV). EudragitⓇ L 100 and EudragitⓇ S 100, containing triethyl citrate as plasticiser, proved to be suitable for manufacturing films with optimal dual in vitro drug-release behaviour. TFV-release can be sustained for several days after film administration and all the drug is released in a few hours in conditions simulating ejaculation. The films' mechanical properties were also deemed suitable for comfortable vaginal administration. Two optimized films were further assessed using HEC-1-A and Ca Ski cell monolayer models and were found to possess favourable drug permeability profiles and drug levels associated to cell monolayer as compared to free TFV. Overall, pH-dependant films containing tenofovir may constitute promising candidates for "smart" vaginal microbicides to protect women from sexual HIV transmission.

Abstract
BACKGROUND Two phase 3 clinical trials showed that use of a monthly vaginal ring containing 25 mg dapivirine was well tolerated and reduced HIV-1 incidence in women by approximately 30% compared with placebo. We aimed to evaluate use and safety of the dapivirine vaginal ring (DVR) in open-label settings with high background rates of HIV-1 infection, an important step for future implementation. METHODS We did a phase 3B open-label extension trial of the DVR (MTN-025/HIV Open-label Prevention Extension [HOPE]). Women who were HIV-1-negative and had participated in the MTN-020/ASPIRE phase 3 trial were offered 12 months of access to the DVR at 14 clinical research centres in Malawi, South Africa, Uganda, and Zimbabwe. At each visit (monthly for 3 months, then once every 3 months), women chose whether or not to accept the offer of the ring. Used, returned rings were tested for residual amounts of dapivirine as a surrogate marker for adherence. HIV-1 serological testing was done at each visit. Dapivirine amounts in returned rings and HIV-1 incidence were compared with data from the ASPIRE trial, and safety was assessed. This study is registered with ClinicalTrials.gov, NCT02858037. FINDINGS Between July 16, 2016, and Oct 10, 2018, of 1756 women assessed for eligibility, 1456 were enrolled and participated in the study. Median age was 31 years (IQR 27-37). At baseline, 1342 (92·2%) women chose to take the DVR; ring acceptance was more than 79% at each visit up until 12 months and 936 (73·2%) of 1279 chose to take the ring at all visits. 12 530 (89·3%) of 14 034 returned rings had residual dapivirine amounts consistent with some use during the previous month (>0·9 mg released) and the mean dapivirine amount released was greater than in the ASPIRE trial (by 0·21 mg; p<0·0001). HIV-1 incidence was 2·7 per 100 person-years (95% CI 1·9-3·8, 35 infections), compared with an expected incidence of 4·4 per 100 person-years (3·2-5·8) among a population matched on age, site, and presence of a sexually transmitted infection from the placebo group of ASPIRE. No serious adverse events or grade 3 or higher adverse events observed were assessed as related to the DVR. INTERPRETATION High uptake and persistent use in this open-label extension study support the DVR as an HIV-1 prevention option for women. With an increasing number of HIV-1 prophylaxis choices on the horizon, these results suggest that the DVR will be an acceptable and practical option for women in Africa.

Holloway IW, Krueger EA, Meyer IH, Lightfoot M, Frost DM, Hammack PL. Longitudinal trends in PrEP familiarity, attitudes, use and discontinuation among a national probability sample of gay and bisexual men, 2016-2018. PLoS One 2020; 15:e0244448. [PMID: 33382743 PMCID: PMC7775083 DOI: 10.1371/journal.pone.0244448] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Accepted: 12/09/2020] [Indexed: 11/18/2022] Open
Abstract
This study explored familiarity with, attitudes toward, uptake and discontinuation of PrEP (Pre-exposure prophylaxis) among a national probability sample of gay and bisexual men. PrEP is one of the most effective biomedical HIV prevention strategies; however, use among gay and bisexual men remains low within the United States. This study used a national probability sample of gay and bisexual men from three age cohorts of men (18-25, 34-41, and 52-59 years at wave 1) who completed three annual surveys between March 2016 and March 2018 (N at wave 1 = 624). Recruitment occurred through a Gallup dual-frame sampling procedure; results for this study came from eligible individuals who consented to be part of the self-administered online or mailed survey questionnaire. We used descriptive data with sampling weights to understand trends in PrEP familiarity, PrEP attitudes and PrEP use across all three time points. Next, PrEP uptake and discontinuation were assessed among men completing all three surveys and who remained eligible for PrEP at all three time points (N = 181). PrEP familiarity increased considerably between 2016 and 2018 among those eligible for PrEP (from 59.8% from wave 1 to 92.0% at wave 3). Favorable attitudes toward PrEP increased more modestly (from 68.3% at wave 1 to 72.7% at wave 3). While PrEP use increased by 90% between the two time points (from 4.1% in 2016 to 7.8% in 2018), this represented a small percentage of overall uptake among eligible participants across time (6.6%). Among respondents who reported PrEP use at wave 1 or wave 2, 33.3% subsequently discontinued PrEP use at a later wave. Findings indicate modest increases in PrEP use between 2016 and 2018 in a national probability sample of sexually-active gay and bisexual men. PrEP discontinuation was high and suggests the need for further research into gay and bisexual men's PrEP discontinuation and persistence.

Abstract
PURPOSE OF REVIEW Advances in short- and long-acting pre-exposure prophylaxis (PrEP) technologies have incentivized the need to understand how individuals make trade-offs and competing decisions regarding PrEP modalities. The purpose of this review was to examine how researchers have conceptualized and measured attributes that are either intuitive and emotional (System 1) or deliberative and cognitive (System 2) in conjoint analysis or discrete choice experiments focused on diverse PrEP technologies among men who have sex with men (MSM). RECENT FINDINGS Across the 9 studies meeting inclusion criteria, 5 included oral PrEP, 3 included topical rectal microbicides, 4 included PrEP injectables, and 1 study focused on an HIV prevention vaccine. Studies have not used uniform metrics, making comparisons difficult. Researchers measured attributes linked to System 2 processing (e.g., cost, efficacy), yet none examined System 1 processing. There is not one product or attribute preferable to all groups. Prevention products will need to be developed and promoted to reflect that diversity. Given that PrEP technologies have been solely informed by System 2 attributes, efforts to integrate System 1 attributes into ongoing and future PrEP choice experiments are pivotal to advance PrEP acceptability research and interventions to support their implementation.

Abstract
OBJECTIVE To estimate the proportion of US HIV-positive men who report a male HIV-negative/unknown status (HIV-discordant) sexual partner taking preexposure prophylaxis (PrEP), and the use of multiple HIV prevention strategies within partnerships. DESIGN The Medical Monitoring Project is a complex sample survey of US adults with diagnosed HIV. METHODS We used data collected during June 2016 to May 2018 among sexually active HIV-positive men who had at least one HIV-discordant male partner (N = 1871) to estimate the weighted prevalence of reporting at least one partner taking PrEP. Among HIV-discordant partnerships (N = 4029), we estimated PrEP use, viral suppression among HIV-positive partners, and condomless anal sex. We evaluated significant (P < 0.05) differences between groups using prevalence ratios with predicted marginal means. RESULTS Twenty-eight percent of sexually active HIV-positive MSM reported at least one HIV-discordant male partner taking PrEP. Twenty percent of HIV-discordant partners were reported to be taking PrEP; 73% were taking PrEP or the HIV-positive partner was virally suppressed. PrEP use was lower among black and Hispanic partners compared with white partners (12% and 19% vs. 27%). Fewer black than white MSM were in partnerships in which PrEP was used or the HIV-positive partner had sustained viral suppression (69% vs. 77%). Condomless anal intercourse was more prevalent in partnerships involving PrEP use and in partnerships involving either PrEP use or sustained viral suppression among the HIV-positive partner. CONCLUSION PrEP use was reported among one in five partners, with disparities between black and white partners. Increasing PrEP use and decreasing racial/ethnic disparities could reduce disparities in HIV incidence and help end the US HIV epidemic.

Abstract
Addressing women's low uptake of HIV pre-exposure prophylaxis (PrEP) requires improved understanding of their product preferences. Such preferences should be contextualized according to other aspects of their reproductive health, including their contraception practices. We investigated women's preferences across 10 PrEP modalities currently available or under study and examined associations between PrEP modality preferences and contraception practices. Heterosexually active women recently engaged in care at Connecticut Planned Parenthood centers (n = 563) completed an online survey. Participants were presented with images and descriptions of 10 PrEP modalities and asked to indicate their preference and specify their reasoning in an open-response format. Participants also reported prior and current use of 16 contraception modalities along with relationship, sexual health, and sociodemographic characteristics. The sample included women ages 18-45 (45.3% 25 or younger) who were predominantly non-Hispanic black (35.7%) or white (33.7%). All PrEP modalities presented were preferred by at least some women, with daily pills (24.9%), injections (24.3%), and invisible implants (14.9%) preferred most commonly. Across all modalities, associated reasoning often centered around ease of use and comfort. Coincidence with contraception modality was the third-most common reason underlying women's preferences. Women currently using the analogous contraception modality versus never having used it had higher odds of preferring PrEP daily pills [adjusted odds ratio (AOR) = 2.03], injections (AOR = 8.45), invisible implants (AOR = 11.63), and vaginal rings (AOR = 8.66). Diversification of available PrEP modalities and prioritization of those coinciding with popular contraception practices-especially daily pills, injections, and implants-could optimize PrEP acceptability, encourage PrEP uptake, and ultimately reduce HIV incidence among women.

Abstract
HIV/AIDS stands as a global burden, and vaginal microbicides constitute a promising strategy for topical pre-exposure prophylaxis. Preceding the development of a microbicide containing tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC), in silico and in vitro studies were performed to evaluate the physicochemical characteristics of both drugs, and to study their biophysical impact in lipid model systems. Results from these pre-formulation studies defined hydrogels as adequate vehicles to incorporate TDF-loaded liposomes and FTC. After studying interactions with mucin, zwitterionic liposomes with a mean diameter of 134 ± 13 nm, an encapsulation TDF efficiency of approximately 84%, and a transition temperature of 41 °C were selected. The chosen liposomal formulation was non-cytotoxic to HEC-1-A and CaSki cells, and was able to favor TDF permeation across polysulfone membranes (Jss = 9.9 μg·cm-2·h-1). After the incorporation of TDF-loaded liposomes and FTC in carbomer hydrogels, the drug release profile was sustained over time, reaching around 60% for both drugs within 3-6 h, and best fitting the Weibull model. Moreover, liposomal hydrogels featured pseudoplastic profiles that were deemed suitable for topical application. Overall, the proposed liposomal hydrogels may constitute a promising formulation for the vaginal co-delivery of TDF/FTC.

Willingness to Use and Adhere to HIV Pre-Exposure Prophylaxis (PrEP) among Men Who Have Sex with Men (MSM) in China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16142620. [PMID: 31340482 PMCID: PMC6678719 DOI: 10.3390/ijerph16142620] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Revised: 07/09/2019] [Accepted: 07/20/2019] [Indexed: 01/23/2023]
Abstract
This study aimed to investigate the levels of willingness to use pre-exposure prophylaxis (PrEP) and intention to adhere to PrEP and to further explore factors associated with PrEP uptake among men who have sex with men (MSM) in China. A total of 524 MSM were recruited from Chengdu, China. Half of the participants had heard of PrEP, and the awareness rate varied from 33.8%, 30.7%, and 7.1% for daily oral PrEP, on-demand PrEP, and long-acting injectable PrEP (LAI-PrEP), respectively. The overall willingness to use any type of PrEP in the next six months was 84.9% if PrEP is effective and provided for free. Participants were less likely to say that they would use PrEP if they used a condom consistently with their regular partners. However, participants were more likely to say that they would use PrEP if they had casual partners in the past month and had higher HIV prevention literacy. The majority of participants intended to adhere to PrEP prescription. More than forty percent (43.1%) of the participants reported that they might reduce condom use if they took PrEP. We found that the overall willingness to use PrEP was high among MSM living in China, but willingness varied across the different types of PrEP.
