Emergency Departments: Patient Screening, Prescribing, and Linkage to Care

In the pursuit of ending the HIV epidemic, U.S. emergency departments (EDs) have emerged as a valuable setting to increase HIV testing and linkage to care. There is limited data available, however, describing the incorporation of HIV prevention initiatives in U.S. EDs. Over the last decade, HIV pre-exposure prophylaxis (PrEP) has significantly changed the HIV prevention landscape globally and very little is known about the provision of PrEP in U.S. EDs. To address this gap in the literature, we conducted a systematic review of peer-reviewed quantitative studies and conference abstracts spanning July 2012 - October 2022. Of 433 citations, 11 articles and 13 abstracts meet our inclusion criteria, representing 18 unique studies addressing PrEP screening, prescribing, and/or linkage to PrEP care.Most studies describe screening processes to identify PrEP-eligible patients (n = 17); most studies leveraged a patient's STI history as initial PrEP eligibility screening criteria. Fewer studies describe PrEP prescribing (n = 2) and/or linkage to PrEP care (n = 8).Findings from this systematic review highlight the potential for U.S. EDs to increase PrEP uptake among individuals at risk for HIV infection. Despite a growing number of studies exploring processes for incorporating PrEP into the ED setting, such studies are small-scale and time limited. Models providing prescribing PrEP in the ED show higher initiation rates than post-discharge engagement models. Electronic health record (EHR)-based HIV screening is valuable, but post-ED linkage rates are low. Our findings emphasize the need to establish best practices for initiating and supporting prevention effective PrEP use in the ED setting.

Communicable Disease Screening and Human Immunodeficiency Virus Prevention in the Emergency Department

Emergency departments (ED) provide care to populations with high rates of communicable diseases, like HIV, hepatitis C virus, and syphilis. For many patients, the ED is their sole entry point into the healthcare system and they do not routinely access screening and prevention services elsewhere. As such, the ED can serve an important public health role through communicable disease identification, treatment, and prevention. In this article, we examine national recommendations, peer-reviewed literature, and expert consensus to provide cutting edge strategies for implementing communicable infectious disease screening and prevention programs into routine ED care.

Impact of screening and doxycycline prevention on the syphilis epidemic among men who have sex with men in British Columbia: a mathematical modelling study

Background

Men who have sex with men (MSM) in British Columbia (BC) are disproportionately affected by infectious syphilis and HIV. In this study, we developed a co-interaction model and evaluated the impact and effectiveness of possible interventions among different MSM subgroups on the syphilis epidemic.

Methods

We designed a deterministic compartmental model, which stratified MSM by HIV status and HIV pre-exposure prophylaxis (HIV-PrEP) usage into (1) HIV-negative/unaware MSM (HIV-PrEP not recommended, not on HIV-PrEP), (2) HIV-negative/unaware MSM with HIV-PrEP recommended (not on HIV-PrEP), (3) HIV-negative/unaware MSM actively on HIV-PrEP, and (4) MSM diagnosed with HIV. We estimated the effect of scaling up syphilis testing frequency from Status Quo to six-, four-, and three-months, increasing the percentage of MSM using doxycycline prevention (Doxy-P) to 25%, 50%, and 100% of the target level, and a combination of both among subgroups (2)-(4). We also assessed the impact of these interventions on the syphilis incidence rates from 2020 to 2034 in comparison to the Status Quo scenario where no intervention was introduced.

Findings

Under the Status Quo scenario, with the expansion of the HIV-PrEP program to improve syphilis testing, the syphilis incidence rate was estimated to peak at 16.1 [Credible Interval (CI):14.2-17.9] per 1,000 person-years (PYs) in 2023 and decrease to 6.7 (CI:3.8-10.9) per 1,000 PYs by 2034. The syphilis incidence rate in 2034 was estimated at 0.7 (0.3-1.3) per 1,000 PYs if MSM diagnosed with HIV could be tested every four months, and at 1.5 (0.7-3.0) per 1,000 PYs if HIV-negative/unaware MSM actively on HIV-PrEP could be tested every three months. By achieving 100% of the target coverage of Doxy-P, the syphilis incidence rate was estimated at 1.4 (0.5-3.4) if focusing on MSM diagnosed with HIV, and 2.6 (1.2-5.1) per 1,000 PYs if focusing on HIV-negative/unaware MSM actively on HIV-PrEP. Under the combined interventions, the syphilis incidence rate could be as low as 0.0 (0.0-0.1) and 0.8 (0.3-1.8) per 1,000 PYs, respectively.

Interpretation

The HIV-PrEP program in BC plays a crucial role in increasing syphilis testing frequency among high-risk MSM and reducing syphilis transmission among this group. In addition, introducing Doxy-P can be an effective complementary strategy to minimize syphilis incidence, especially among MSM diagnosed with HIV.

Disparities in HIV Testing and PrEP Awareness for Black Women who Inject Drugs in San Francisco, California

HIV disproportionately affects Black/African Americans (AA), while PrEP is under-utilized by Black/AA, women, and people who inject drugs (PWID). In San Francisco, California's National HIV Behavioral Surveillance among PWID in 2022, Black/AA women were the least likely to be tested for HIV among all groups by sex and race/ethnicity and the least likely to be aware of PrEP among women. Yet, Black/AA women were no less likely to see a healthcare provider in the last year. Data suggest that providers' failure to discuss and address HIV risk with Black/AA female PWID is a major barrier to accessing effective care and prevention. El VIH afecta de manera desproporcionada a Black/afroamericanos (AA), mientras que la PrEP está infrautilizada por los Black/AA, las mujeres y las personas que se inyectan drogas (PWID). En la National HIV Behavioral Surveillance de PWID de San Francisco, California en 2022, las mujeres Black/AA eran las que menos probabilidades tenían de someterse a la prueba del VIH entre todos los grupos por sexo y raza/etnia y las que menos probabilidades tenían de conocer la PrEP entre las mujeres. Sin embargo, las mujeres Black/AA no tenían menos probabilidades de acudir a un profesional sanitario en el último año. Los datos sugieren que el hecho de que los proveedores no hablen ni aborden el riesgo de VIH con las PWID de raza Black/AA es un obstáculo importante para acceder a una atención y prevención eficaces.

Advantages and limits of remote consultations for HIV pre-exposure prophylaxis health pathway: ePrEP qualitative study

OBJECTIVE

Because of a high rate of HIV diagnosis and restricted medical access in the Centre-Val de Loire region in France , remote consultations (RC) with a community-based approach has been implemented to promote access to healthcare. Our study aimed to determine whether RC could improve access to pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) as part of the healthcare pathway associated with PrEP.

MATERIALS AND METHODS

A qualitative approach involving semi-structured interviews with 17 MSM and 3 physicians from specialized sexual health centres was performed, with a mean duration of interview over one hour. The research focused on the health pathway associated with PrEP, from initial awareness to ongoing prescription and follow-up.

RESULTS

Transitioning PrEP consultations to RC is feasible, but concerns about a potential decline in care quality compared to traditional sexual health centres follow-ups were noted. Both MSM and physicians recognized that RC could complement face-to-face approaches, especially in terms of organizational benefits. In rural areas, access to specialists through RC was seen as a partial solution, though it could be hindered by barriers in accessing laboratory testing and pharmacy services, like fear of stigmatization. More generally, distrust of medication and the difficulty of discussing sexuality with a GP were highlighted, which could limit the uptake of PrEP without access to specialists.

CONCLUSIONS

The initiation and uptake of PrEP among MSM are more effectively influenced by initiatives that provide information, reassurance, and facilitate initial procedures, rather than solely through RC. A strategy combining digital and community-based approaches, along with medical expertise, is recommended to increase PrEP utilization among MSM.

High study participation but diverging adherence levels: qualitatively unpacking PrEP use among adolescent girls and young women over two years in Eastern Cape, South Africa

In Southern and Eastern Africa, initiation of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been high among adolescent girls and young women (AGYW) offered PrEP. However, persistence and prevention-effective use of PrEP among this critical group continues to be a challenge. We conducted a qualitative sub-study of AGYW from the Community PrEP Study in Eastern Cape Province, South Africa who had high rates of pick up for monthly PrEP refills over two years, but differing levels of PrEP adherence based on tenofovir-diphosphate (TFV-DP) measurements in dried blood spots (DBS). Contrasting 22 AGYW with low versus high levels of TFV-DP in DBS, we qualitatively explored factors which influenced PrEP persistence vs. non-persistence, unique patterns of PrEP use (e.g., discarding or stockpiling), and participant recommendations for improving AGYW prevention-effective use of PrEP in the future. Results showed that PrEP misconceptions and mistrust among participants' social networks negatively influenced adherence. In comparison, supportive families and/or partners and personal trust that PrEP works positively influenced adherence. Those with low adherence described being motivated to come to the site for other study benefits (e.g., reimbursement money, snacks, sanitary pads) and discarding PrEP to avoid stigma associated with being seen with pills. Future PrEP implementation strategies should focus on involving families and partners in PrEP support for AGYW and minimizing PrEP stigma at a community level.Trial registration NCT03977181.

Dynamicity of HIV Pre-exposure Prophylaxis Usage Pattern and Association with Executed Adherence in MSM: An Implementation Study in Hong Kong

Pre-exposure prophylaxis (PrEP) use has been shown to be effective for HIV prevention in men who have sex with men (MSM). PrEP use coverage aside, maintenance of high PrEP adherence is crucial in ensuring the achievement of HIV prevention. In this PrEP implementation study in Hong Kong, we examined the patterns of PrEP use in MSM and evaluated their association with prevention-effective adherence for HIV prevention. In January 2020-June 2021 in Hong Kong, 312 recruited MSM (median 30 years old) were followed up for 1 year, with HIV and creatinine testing, consultation, and PrEP refill. No HIV breakthrough infection was observed. As a measure of prevention-effective adherence, executed adherence (EA) was expressed as the proportion of days with HIV risk that were protected by PrEP and/or condom in 6 months. In 65,585 diary entries of 215 MSM, the median proportion of EA achieved was 89% (IQR 84-93%). Three latent classes of PrEP users were identified by latent class analysis. Taking Class 1 "daily dominant PrEP" (n = 113, 53%) as reference, Class 2 "episodic PrEP" (n = 76, 35%) was adopted by MSM with less sexual activity, had less PrEP refill and lower EA level, while Class 3 "mixed PrEP schedule" (n = 26, 12%) MSM were more sexually active but with a similar EA level. The study findings showed varied and dynamic PrEP usage patterns in the real-world setting. Strategies for promoting adherence are needed to ensure the maintenance of high EA level among PrEP-using MSM especially those on episodic PrEP schedule.

Pilot Randomized Controlled Trial of Game Plan for PrEP: A Brief, Web and Text Message Intervention to Help Sexual Minority Men Adhere to PrEP and Reduce Their Alcohol Use

Suboptimal adherence to oral PrEP medications, particularly among younger sexual minority men (SMM), continues to be a key barrier to achieving more substantial declines in new HIV infections. Although variety of interventions, including web and text-message-based applications, have successfully addressed PrEP adherence, very few have addressed the potential influence of alcohol. This pilot study explored whether the Game Plan for PrEP, a brief, web-based and text messaging intervention, helped promote PrEP persistence and adherence and reduced condomless sex and alcohol use. Seventy-three heavy-drinking SMM on PrEP were recruited online from states with Ending the HIV Epidemic jurisdictions and randomly assigned 1:1 to receive either the Game Plan for PrEP intervention or an attention-matched control. We collected online surveys assessing primary outcomes at one, three, and six months post-enrollment. As secondary outcomes, we also collected dried blood spot samples at baseline, three, and six months to analyze for biomarkers of PrEP and alcohol use. Our results showed that the odds of stopping PrEP or experiencing a clinically meaningful lapse in PrEP adherence (≥ 4 consecutive missed doses) were not different across the two conditions. We also did not find evidence of any differences in condomless sex or drinking outcomes across conditions, although participants in both conditions reported drinking less often over time. These findings were consistent across both self-reported outcomes and biomarkers. Overall, we did not find evidence that our brief, web and text messaging intervention encouraged more optimal PrEP coverage or moderate their alcohol use.

The Moderating Effects of HIV Relevant Factors on the Relationship Between Intimate Partner Violence and Intention to Start HIV Pre-exposure Prophylaxis (PrEP) Among Cisgender Women

Intimate partner violence (IPV) and HIV are serious and related public health problems that detrimentally impact women's health. Because women who experience IPV are more likely to acquire HIV, it is critical to promote HIV prevention strategies, such as HIV pre-exposure prophylaxis (PrEP), that increase autonomy. This study of cisgender women eligible for HIV PrEP took place between 2017 and 2019 in Philadelphia and New York City. This study aimed to examine the relationship between four types of IPV (control, psychological, physical, sexual) and intention to start PrEP among PrEP-eligible cisgender women and assess the extent to which HIV relevant factors moderated the association between IPV experience and intention to start PrEP. In this sample of PrEP-eligible women (n = 214), 68.7% indicated intention to start PrEP in the next 3 months. Ethnicity was strongly associated with intention to start PrEP, with Hispanic women having the highest odds of intending to start PrEP in the next 3 months. Having a controlling partner significantly predicted intention to start PrEP. Women with more than one sex partner and a controlling partner had higher odds of intending to start PrEP as compared with those who had one or no partners and had no IPV control. These findings point to a need for patient-centered interventions that address the need for safety and autonomy among cisgender, PrEP-eligible women.

Multifaceted Barriers to Rapid Roll-out of HIV Pre-exposure Prophylaxis in China: A Qualitative Study Among Men Who Have Sex with Men

BACKGROUND

Oral pre-exposure prophylaxis (PrEP) as a safe and effective antiretroviral medicine-based prevention against HIV has not been widely adopted by gay, bisexual, and other men who have sex with men (MSM) in China. A deeper understanding of barriers and facilitators to PrEP uptake is needed to inform the development of effective interventions.

METHOD

During July-August 2020, we conducted one-on-one semi-structured interviews with 31 Chinese MSM with varied PrEP use experiences (PrEP-naïve, former, and current PrEP users). Interviews were digitally recorded and transcribed in Chinese. Informed by the Information-Motivation-Behavioral Skills Model (IMB), we analyzed the data using a thematic analysis approach to identify the barriers and facilitators to PrEP uptake among Chinese MSM.

RESULTS

Major barriers to PrEP uptake among MSM in the sample included uncertainty about PrEP efficacy and lack of PrEP education (information), concerns over potential side effects and cost (motivation), and difficulties in identifying authentic PrEP medications and managing PrEP care (behavioral skills). Facilitators include the perceived benefit of PrEP in improving the quality of sex life and control over health. At the contextual level, we also identified barriers to PrEP access from a thriving informal PrEP market and stressors related to being MSM.

CONCLUSION

Our findings identified a need to invest in non-discriminatory public health messaging of PrEP, explore options for MSM-friendly provision of PrEP outside of traditional HIV care settings, and be attentive to the unique context of an established informal PrEP market in future PrEP initiatives.

Providing medication for opioid use disorder and HIV pre-exposure prophylaxis at syringe services programs via telemedicine: a pilot study

BACKGROUND

People who inject drugs (PWID) are at high risk for opioid overdose and infectious diseases including HIV. We piloted PARTNER UP, a telemedicine-based program to provide PWID with medication for opioid use disorder (MOUD) with buprenorphine/naloxone (bup/nx) and oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emtricitabine through two syringe services programs (SSP) in North Carolina. We present overall results from this project, including participant retention rates and self-reported medication adherence.

METHODS

Study participants met with a provider for an initial in-person visit at the SSP, followed by weekly telemedicine visits in month 1 and then monthly until program end at month 6. Participants were asked to start both MOUD and PrEP at initiation but could choose to discontinue either at any point during the study. Demographics and health history including substance use, sexual behaviors, and prior use of MOUD/PrEP were collected at baseline. Follow-up surveys were conducted at 3- and 6-months to assess attitudes towards MOUD and PrEP, change in opioid use and sexual behaviors, and for self-reported medication adherence. Participant retention was measured by completion of visits; provider notes were used to assess whether the participant reported continuation of medication.

RESULTS

Overall, 17 persons were enrolled and started on both bup/nx and PrEP; the majority self-identified as white and male. At 3 months, 13 (76%) remained on study; 10 (77%) reported continuing with both MOUD and PrEP, 2 (15%) with bup/nx only, and 1 (8%) with PrEP only. At 6 months, 12 (71%) remained on study; 8 (67%) reported taking both bup/nx and PrEP, and 4 (33%) bup/nx only. Among survey participants, opioid use and HIV risk behaviors decreased. Nearly all reported taking bup/nx daily; however, self-reported daily adherence to PrEP was lower and declined over time. The most common reason for not continuing PrEP was feeling not at risk for acquiring HIV.

CONCLUSIONS

Our study results show that MOUD and PrEP can be successfully administered via telemedicine in SSPs. PrEP appears to be a lower priority for participants with decreased continuation and adherence. Low perception of HIV risk was a reason for not continuing PrEP, possibly mitigated by MOUD use. Future studies including helping identify PWID at highest need for PrEP are needed.

Transient bacteremia following the removal of four different types of rapid palatal expanders

PURPOSE

General health related recommendations for prophylactic measures in connection with orthodontic treatments are limited due to the lack of evidence-based data. This study aimed to investigate the development of transient bacteremia following the removal of four types of rapid palatal expanders (RPE).

METHODS

Seventy-five individuals aged 10-18 years undergoing rapid palatal expansion with four types of RPE were categorized according to the type of RPE used in their treatment: banded tooth-borne (group A (1), n = 17), banded tooth- and tissue-borne (group A (2), n = 17), bonded tooth-borne (group B (1), n = 18), and bonded tooth- and tissue-borne (group B (2), n = 23). Gingival inflammation was assessed using the gingival index one day before RPE removal. Furthermore, samples of blood (5 ml each) were collected before and 3 min after RPE removal. The groups were statistically evaluated for comparability with respect to sex, age, or wear time of the RPE and to the gingival index. In addition, the prevalence of bacteremia in the different groups was evaluated and statistically compared.

RESULTS

No significant difference was found among the groups (p > 0.05) for sex, age, and RPE wear time. Mean gingival index was higher in group B (2) than in group A (1) (p < 0.05). The prevalence of bacteremia did not differ significantly between groups. Streptococcus species were identified in all bacteremia cases. The bacteremia prevalence of the groups was as follows: group A (1), 11.8%; group A (2), 23.5%; group B (1), 16.7%; and group B (2), 30.4%.

CONCLUSION

This investigation demonstrated that removal of a RPE could cause bacteremia, but the RPE design did not affect the prevalence of bacteremia. The results of this study support the necessity of prophylaxis measures before RPE removal in indicated patients.

Incidence of sexually transmitted infections and screening models among pre-exposure prophylaxis users

INTRODUCTION

There is discussion about the frequency of STI screening among pre-exposure prophylaxis (PrEP) users. The aim of this study was to analyse the incidence of STIs and to evaluate different screening models in order to optimise the follow-up.

METHODOLOGY

A prospective study was conducted between 2017 and 2023, including 138 PrEP users in a STI clinic. Participants were tested for STIs every three months. Unscheduled visits were performed for those with STI-related symptoms or for people who were notified for an STI by a sexual partner. We performed a survival analysis of repeated events, estimating the cumulative incidence (CI) and incidence rate (IR).

RESULTS

The overall CI by quarterly screening was 8.3 (95% CI: 7.6-9.1) infections per person over six years, with a decreasing trend. The most frequently diagnosed pathogen was Neisseria gonorrhoeae, with a IR of 0.76 (95% CI: 0.68-0.84). If the frequency of screening is reduced to every six months, the IR of STIs is reduced by (95% CI: 0.5-0.66) infections per user per year, and at 12 months by 0.82 (95% CI: 0.73-0.89). In the case of no pharyngeal or urethral screening, IR is reduced by 0.37 (95% CI: 0.32-0.42) infections per person per year and in those over 35 years of age by 0.33 (95% CI: 0.25-0.4). Eliminating unscheduled visits, the reduction in IR is 0.33 (95% CI: 0.24-0.42).

CONCLUSIONS

The incidence of STIs among PrEP users is high, especially in the rectum, but it does not increase over time. STI screening could be optimised reducing the frequency of pharyngeal and urethral testing, particularly in those over 35 years of age. It is essential to redistribute health resources for unscheduled visits, which have been shown to be the most cost-effective screening.

Factors Associated with the Awareness of and Willingness to Use HIV Pre-exposure Prophylaxis Among Gay, Bisexual, and Other Men Who Have Sex with Men, Baltimore, MD, 2017-2019

Pre-exposure prophylaxis (PrEP) is an effective tool in protecting persons from acquiring HIV infection through sex or injection drug use. However, awareness and willingness to use PrEP among Black gay, bisexual, and other men who have sex with men (BMSM) remain suboptimal compared to White MSM (WMSM) in the United States. Our aims were to (1) assess the factors associated with PrEP awareness and willingness to use PrEP among MSM and (2) compare the PrEP perceptions among BMSM versus non-Black MSM. Data were drawn from two cross-sectional behavioral surveys in Baltimore, MD: Behavioral Surveillance Research (BESURE) conducted in 2017, and Safe Spaces 4 Sexual Health (SS4SH), conducted in 2018 and 2019. Descriptive statistics were used to summarize the study population. We used Poisson regression models to identify variables associated with awareness of PrEP and willingness to use PrEP. PrEP perceptions were assessed via 13 items scored on a 5-point Likert scale. Finally, we conducted a post-hoc exploratory bivariate analysis of the relationship between PrEP perception and willingness to use PrEP, stratified by race/ethnicity. A total of 261 MSM participated in this study. Many of the participants were aware of PrEP (75.1%). Factors associated with greater PrEP awareness included having greater than a high school education (aRR 1.22, 95% CI 1.04, 1.43); and earning more than $25,000 annually (aRR 1.24, 95% CI 1.08, 1.42). Participants who had received money in exchange for sex one or more times were less likely to be aware of PrEP (aRR 0.59, 95% CI 0.36, 0.95). More than half of the participants were willing to use PrEP (55.3%). In bivariate and multivariable analyses, demographic or behavioral characteristics were not significantly associated with willingness to use PrEP. Higher agreement with the following statements was associated with lower willingness to use PrEP: "Having to take a pill every day is difficult" (RR 0.89, 95% CI 0.82-0.97) and, "I am concerned about the side effects of PrEP" (RR 0.89, 95% CI 0.82-0.96), and "PrEP is for people who have riskier sex lives than I do" (RR 0.86, 95% CI 0.78-0.95). Conversely, higher willingness to use PrEP was associated with comfortable having sex without a condom (RR 1.11, 95% CI 1.02-1.21), less anxious about sex (RR 1.12, 95% CI 1.02-1.24), and my friends think that I should take PrEP (RR 1.19, 95% CI 1.07-1.32). We found BMSM compared to non-Black MSM had higher mean scores related to taking a daily pill (p = 0.041), concerns about side effects (p = 0.012), concerns about people thinking they had HIV (p = 0.001), concerns about the financial costs of PrEP (p = 0.038) and caution when dealing with healthcare organizations/medical mistrust (p = 0.019). Perceptions with a statistically significant lower score among BMSM versus non-Black MSM included statements such as, comfortable having sex without a condom (p = 0.003) and less anxious about sex (p < 0.001). We conclude HIV prevention strategies, programs, and interventions should be cognizant of PrEP perceptions that facilitate or hinder PrEP uptake in Baltimore City, MD.

Factors associated with discussing HIV pre-exposure prophylaxis (PrEP) among Jamaican medical providers

BACKGROUND

The Ministry of Health and Wellness of Jamaica has endorsed the use of pre-exposure prophylaxis (PrEP) as an HIV prevention strategy; however, PrEP was not included in the national HIV prevention program in 2021.

METHODS

A cross-sectional online study involving physicians in Jamaica was conducted in 2021 to describe PrEP awareness, beliefs, attitudes, and practices. The study also assessed individual and social factors associated with discussing PrEP with patients and willingness to prescribe PrEP.

FINDINGS

The mean age and standard deviation (SD) of the 69 physicians who completed the survey were 45.5 ± 13.6 years. Most of the participants (80%) reported that they were somewhat familiar with PrEP. PrEP attitude and perceived comfort in prescribing PrEP were moderate among participating physicians, with a mean and SD of 3.9 ± 0.8 and 3.6 ± 0.9 respectively. Six percent of physicians reported that they had prescribed PrEP and 17% had discussed PrEP with their patients in the past year. However, most (90%) reported that they were willing to prescribe PrEP after being informed about it. In the unadjusted model, identifying as Christian (compared to non-Christian) and reporting stronger homophobic beliefs were associated with reduced odds of discussing PrEP with patients. In the multivariable model, only homophobia remained statistically significant (OR, 0.24; 95% CI: 0.07-0.63).

CONCLUSION

The findings suggest that physicians in Jamacia may be willing to prescribe PrEP; however, homophobia is a barrier to discussions, underscoring the need for the Ministry of Health and Wellness to recognize the role that homophobia plays in the national HIV program to further reduce HIV incidence in Jamaica.

Preferences for Long-Acting PrEP Products Among Women and Girls: A Quantitative Survey and Discrete Choice Experiment in Eswatini, Kenya, and South Africa

While oral pre-exposure prophylaxis (PrEP) can substantially reduce HIV risk, there are important barriers to uptake and adherence. We explored preferences for long-acting injectable and implantable PrEP among women and girls in Eswatini, Kenya, and South Africa. We conducted an online quantitative survey and discrete choice experiment (DCE) among adolescent girls (15-17), young women (18-29), and adult women (30-49). Participants completed a survey about their demographics and behavior and a DCE with 5 attributes (format, insertion location, number of insertions, dual-protection, and palpability). We recruited 1236 respondents (Eswatini = 420; Kenya = 350; South Africa = 493) in May 2022. Most participants were sexually active (72%), nearly 29% of whom reported recently engaging in transactional sex. 46% had heard of oral PrEP, but of those, only 16% reported having ever used it. Product format and dual-protection were significant predictors of product choice. Relative to a 2-month injection, participants had 1.76 times the odds (95% CI 1.08-2.04) of choosing a 6-month injectable, and 1.70 the odds (95% CI 1.06-1.92) of choosing a 12-month removable implant. Compared to a single-indication product, respondents had 2.46 times the odds (95% CI 1.04-2.68) of preferring a product also protecting against pregnancy, and 2.81 the odds (95% CI 1.04-3.05) of choosing a product that also protected against STIs. Adolescent girls and women in these countries showed strong preferences for longer-acting PrEP product formats, as well as those offering dual-protection. Introduction of long-acting options could improve PrEP uptake and reduce HIV burdens in east and southern African settings.

Determination of intracellular tenofovir-diphosphate and emtricitabine-triphosphate concentrations in dried blood spots for pre-exposure prophylaxis adherence

OBJECTIVES

We measured the intracellular concentrations of tenofovir-diphosphate (TFV-DP) and emtricitabine-triphosphate (FTC-TP) in dried blood spots (DBS) for pre-exposure prophylaxis (PrEP) adherence using sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS).

METHODS

A total of 191 DBS were obtained from 85 participants who were receiving tenofovir disoproxil fumarate (TDF; 300 mg) and emtricitabine (FTC; 200 mg) as PrEP at the Sexual Health Clinic, National Center for Global Health and Medicine, Tokyo, Japan. DBS punch (3 mm) added to 25 μL of 50% methanol and 400 μL of internal standard solution was used for solid phase extraction. Chromatographic separation was achieved on an Atlantis Premier BEH C18 AX Column (50 mm × 2.1 mm i.d.; particle size 1.7 μm) using gradient elution (flow rate: 0.6 mL/min); injection volume: 7 μL and run time: 5.5 min. Calibration curves for the two drugs were linear in the range 0.05-12.5 ng/punch.

RESULTS

We determined the intracellular TFV-DP and FTC-TP concentrations in 191 DBS obtained from 85 patients administered with TDF and FTC as PrEP. The analytical performance data (calibration curve and QC samples) for all the analytical runs met the acceptance criteria. Intracellular concentrations of TFV-DP and FTC-TP in the DBS remained stable for at least 24 h after oral administration.

CONCLUSIONS

A multiplex LC-MS/MS method was successfully developed for DBS, which can be useful for monitoring the levels of TFV-DP and FTC-TP in individuals receiving PrEP.

High Propensity to Switch to Long-acting Injectable HIV PrEP with Cabotegravir in a Cohort of Oral PrEP Experienced Men who Have Sex with Men in Italy

Aim was to investigate the propensity to switch to long-acting injectable HIV pre-exposure prophylaxis (PrEP) with cabotegravir among oral PrEP-experienced men who have sex with men. Out of 377 PrEP users, 325 (86.2%) were interested (would like = 210) or considering (would consider = 115) switch to long-acting PrEP. At multivariable analysis, the odds ratio of interest in long-acting PrEP in non-adherent vs. adherent individuals to oral PrEP was 5.03 (95%CI = 1.73-14.61,p = 0.003) and of consideration 1.63 (95%CI = 0.51-5.23,p = 0.410). We observed very high propensity to switch to long-acting PrEP, particularly among non-adherent users. Rapid availability of long-acting PrEP might address unmet needs of PrEP users in Italy.

Strategies to Close the PrEP Uptake Gap Among Transgender People and Men Who Have Sex with Men in Tshwane, South Africa: Perspectives from the Community

HIV Pre-exposure Prophylaxis (PrEP) uptake among transgender (TG) people and gay men and other men who have sex with men (MSM) remains low, despite South Africa being the first African country to approve PrEP. This mixed-methods study used a two-phase explanatory sequential design: (1) quantitative analysis of cross-sectional surveys followed by (2) qualitative in-depth interviews. This study explored facilitators and barriers to PrEP uptake to identify strategies to increase utilization in these key populations. We conducted 202 cross-sectional surveys and 20 in-depth interviews between July 2021 and March 2022 in Soshanguve, Tshwane, Gauteng. Quantitative data were analyzed using univariate logistic regression; thematic analysis was performed for qualitative data. Findings show high willingness to use PrEP but low PrEP uptake. We outline strategies to facilitate PrEP use: (1) demystify daily PrEP by deploying community-engaged PrEP education campaigns; (2) capitalize on existing peer networks; and (3) expand accessible and culturally responsive PrEP service delivery models. We provide feasible recommendations to close the PrEP uptake gap in these key populations in South Africa.

Behavior Change Among HIV-Negative Men Who Have Sex with Men Not Using PrEP in the United States

This study measures changes in condomless anal sex (CAS) among HIV-negative men who have sex with men (MSM) who are not taking pre-exposure prophylaxis (PrEP). It considers the 2014-2019 cycles of the American Men's Internet Survey, a serial, cross-sectional web-based survey of US cisgender MSM aged ≥ 15 years, in which ~ 10% of each year's sample is drawn from the previous year. Among those surveyed for 2 years who remained HIV-negative and off PrEP, reports of having any CAS and of CAS partner number were compared across years. We disaggregated by partner HIV status, and considered demographic predictors. The overall population saw a significant 2.2 percentage-point (pp) increase in reports of any CAS year-over-year. Sub-populations with the largest year-on-year increases were 15-24-year-olds (5.0-pp) and Hispanic respondents (5.1-pp), with interaction (young Hispanic respondents = 12.8-pp). On the relative scale, these numbers correspond to 3.2%, 7.2%, 7.3% and 18.7%, respectively. Absolute increases were concentrated among partners reported as HIV-negative. Multivariable analyses for CAS initiation found effects concentrated among Hispanic and White youth and residents of fringe counties of large metropolitan areas. CAS partner number increases were similarly predicted by Hispanic identity and young age. Although condom use remains more common than PrEP use, increasing CAS among MSM not on PrEP suggests potential new HIV transmission pathways. Concentration of increases among 18-24-year-old MSM portends future increases in the proportion of newly diagnosed HIV that occur among youth. Concentration among young Hispanic MSM will likely expand existing disparities. Although reducing barriers to PrEP remains vital, condom promotion for MSM remains a key public health practice and appears to be missing key audiences. LGBTQ+-inclusive sex education is one avenue for enhancing these efforts.

[Daily use of HIV pre-exposure prophylaxis among gay, bisexual and other men who have sex with men in Spain: Prevalence and associated factors]

OBJECTIVE

We aim to estimate the prevalence of daily HIV pre-exposure prophylaxis (PrEP) use 6 months after public funding approval in Spain and identify associated factors in a national sample of gay, bisexual and other men who have sex with men (GBMSM).

MATERIAL AND METHODS

We analysed 4692 HIV-undiagnosed GBMSM men recruited via an online questionnaire distributed nationally via gay contact apps and websites between May and July 2020. We estimated the proportion of participants using daily PrEP and identified associated factors using Poisson regression with robust variance.

RESULTS

Daily PrEP use was reported by 2.8% (95% CI 2.3-3.3) of all participants. Daily PrEP use was independently associated with being recruited into community programmes, being older than 30 years, living in a large city, living with men, having condomless anal intercourse with more than 10 sexual partners, using drugs for sex, especially chemsex drugs, and being diagnosed with a sexually transmitted infection.

CONCLUSION

Six months after PrEP was approved in Spain, the prevalence of daily use is low in a national sample of GBMSM men. There is a need to promote access, demand and interest in PrEP, especially among young GBMSM men, those living in small and medium-sized cities, and those who hide their relationships with other men.

Study protocol of a randomized controlled trial to assess the efficacy of the "PrEPare for Work" intervention to enhance PrEP uptake and optimize adherence for HIV prevention among male sex workers in the U.S

BACKGROUND

Male sex workers (MSWs), specifically cisgender men who exchange sex for money, goods, drugs, or other items of value with other cisgender men, are at high risk for HIV infection. Compared to men not engaged in sex work, MSWs are more likely to engage in frequent condomless sex with paying and non-paying sexual partners. While MSWs are often included as a subgroup of gay and bisexual men, data show that a large proportion identify as heterosexual; additionally, most MSWs do not identify as "sex workers." This places MSWs in a unique position where they may not engage with traditional HIV prevention programs, and when they do, they may not feel comfortable, leading to poor retention. Thus, HIV prevention interventions that address MSWs' unique life circumstances and provide support in exploring their sexual health options are needed.

METHODS

In this protocol paper, we describe the design and procedures for a National Institute of Health-funded, randomized controlled trial testing the efficacy of "PrEPare for Work,"- a theory-based, manualized PrEP uptake and adherence intervention for MSW - using a 2-stage randomization design. Stage 1: MSWs are equally randomized to receive either the "PrEPare for Work Stage 1 intervention" (strength-based case management and facilitated PrEP linkage) or Standard of Care (SOC) to evaluate successful PrEP uptake (prescription filled) within two months post-randomization. Stage 2: Those who initiate PrEP are then equally re-randomized to receive either the "PrEPare for Work Stage 2 intervention" (1-on-1 skills training, problem-solving, and motivational interviewing adherence counseling and personalized, daily text message reminders) or SOC to assess adherence (Tenofovir concentrations in hair) over 12 months of follow up. Planned analyses will examine intervention efficacy, specific conceptual mediators, and hypothesized moderators.

DISCUSSION

Based on our extensive preliminary research, multi-component, theory-informed interventions targeting this subpopulation of MSWs' unique life circumstances are urgently needed. In this study, we are evaluating whether "PrEPare for Work" can improve PrEP uptake and adherence among MSWs. If this intervention is efficacious, it would be readily disseminated to diverse community organizations that serve MSWs and possibly other community or clinic-based settings.

Long-acting Injectable PrEP Interest and General PrEP Awareness among People who Inject Drugs in the San Diego-Tijuana Border Metroplex

Long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP) could help overcome multilevel challenges to HIV prevention for people who inject drugs (PWID), including those in the binational San Diego-Tijuana metroplex. Yet, general PrEP awareness and interest in LAI-PrEP remain underexplored among PWID. From 2020 to 2021, 562 HIV-negative PWID in San Diego and Tijuana completed surveys assessing general PrEP awareness and interest in oral and LAI-PrEP. Modified Poisson regression examined factors associated with general PrEP awareness. Multinomial logistic regression assessed factors associated with interest in both oral and LAI-PrEP, oral PrEP only, LAI-PrEP only, or neither. General PrEP awareness was low (18%) and associated with experiencing unsheltered homelessness (adjusted prevalence ratio [APR] = 1.50, 95% confidence interval [CI]: 0.96-2.33), past 6-month fentanyl injection (APR = 1.53, 95% CI: 1.04-2.25), and transactional sex (APR = 1.71, 95% CI: 1.06-2.76). Interest in oral PrEP only was most common (44%), followed by LAI-PrEP only (25%) and neither (16%). Compared to the odds of being interested in LAI-PrEP only, the odds of being interested in oral PrEP only were lower among those who were stopped by police (AOR = 0.38, 95% CI: 0.22-0.65), reported past 6-month fentanyl injection (AOR = 0.33, 95% CI: 0.20-0.56), polydrug use (AOR = 0.48, 95% CI: 0.27-0.86), injecting multiple times daily (AOR = 0.26, 95% CI: 0.14-0.46), receptive syringe use (AOR = 0.30, 95% CI: 0.19-0.49), and higher perceived HIV risk (AOR = 0.24, 95% CI: 0.15-0.39). Interest in LAI-PrEP was more common among PWID reporting social and structural factors that could interfere with oral PrEP adherence, suggesting LAI-PrEP implementation could increase PrEP coverage among those most vulnerable to HIV.

AIDSImpact special issue: factors associated with PrEP use in a community sample of African American men who have sex with men (MSM) and transgender women (TGW) in the United States Midwest

Black sexual minority men who have sex with men (MSM) in the United States are at disparate risk for contracting HIV infection, but pre-exposure prophylaxis (PrEP) use is suboptimal. Social network methods were used to recruit a community sample of racial minority MSM and transgender women (TGW) in two Midwestern US cities. 250 PrEP-eligible (HIV-negative) participants completed measures assessing current and intended PrEP use; demographic characteristics; PrEP knowledge, attitudes, norms, stigma, and self-efficacy; and structural barriers to PrEP. Multivariate analyses established predictors of current and intended PrEP use. Only 12% of participants reported currently using PrEP, which was associated with greater PrEP knowledge and not having a main partner, with trends for greater PrEP use by younger participants and those with partners living with HIV. Among participants not currently on PrEP, strength of PrEP use intentions was associated with higher PrEP knowledge, PrEP descriptive social norms, and PrEP use self-efficacy. This study is among few to directly compare Black who have adopted PrEP with those who have not. Its findings underscore the potential benefits of employing social network approaches for strengthening PrEP use peer norms, increasing PrEP knowledge and self-efficacy, and optimizing PrEP uptake among racial minority MSM and TGW.

Trajectories of anxiety and depression among Chinese men who have sex with men on pre-exposure prophylaxis: a group-based trajectory model approach

BACKGROUND

Anxiety and depression can influence adherence to Pre-exposure Prophylaxis (PrEP). However, there is limited research on the temporal dynamics of anxiety and depression among men who have sex with men (MSM) using PrEP.

METHODS

From December 2018 to November 2020, we administered the Hospital Anxiety and Depression Scale (HADS) to participants in the China Real-World Oral Intake of PrEP (CROPrEP) to measure their anxiety and depression levels. The group-based trajectory model (GBTM) depicted the dynamic changes of anxiety and depression scores over time.

RESULTS

A total of 1023 MSM were included, with 4523 follow-up assessments. The GBTM categorized the trajectories into three distinct patterns: consistently low (54.8% for anxiety, 60.7% for depression), consistently moderate (39.3% for anxiety, 31.4% for depression), and high but bell-shaped (5.9% for anxiety, 7.9% for depression). Higher anxiety levels were associated with being aged 18-30 years old, earning less than US$619 per month, female-identifying, adopting the bottom sexual role with men, and having two or more anal sex partners in the past three months; similarly, higher depression levels correlated with a monthly income under US$619, female-identifying, sexual behavior as bottom and a positive syphilis at baseline. PrEP adherence was notably lower in the high but bell-shaped anxiety and depression group compared to the other groups, particularly at the 12th-month follow-up.

CONCLUSIONS

Close monitoring of anxiety and depression levels in MSM on PrEP is crucial. Provision of targeted mental health support is essential to enhance PrEP effectiveness.

The Implications of PrEP Use, Condom Use, and Partner Viral Load Status for Openness to Serodifferent Partnering Among US Sexual Minority Men (SMM)

PrEP has been reported to facilitate openness to serodifferent sexual partnerships among sexual minority men (SMM). However, other aspects of a sexual scenario likely come into play, including whether or not condoms are used and whether or not the partner living with HIV has an undetectable viral load. This online survey study evaluated the association between PrEP status and openness to serodifferent partnering, as well as the effects of various sexual scenario variables (condom use and partner's viral load) among 268 HIV-negative SMM in the US. Each participant reported their PrEP status and rated their openness to serodifferent partnering in four sexual scenarios, which varied by condom use (with/without) and partner viral load status (detectable/undetectable). Analyses of covariance (ANCOVAs) were conducted to assess differences in openness to serodifferent partnering by PrEP status in each scenario, adjusting for background characteristics. A two-way repeated measures ANCOVA and a three-way mixed factorial ANCOVA, including PrEP status as a between-subjects variable, were also performed to assess the effects of condom use and partner viral load status on openness. Across all scenarios, current PrEP users expressed significantly greater openness to serodifferent partnering compared to participants who had never used PrEP. Current PrEP users were also more likely than former PrEP users to consider partnering with someone with an undetectable viral load without using condoms. Both PrEP users and PrEP-inexperienced individuals had greater openness to serodifferent partnering with a partner having an undetectable (vs. detectable) viral load, which was magnified by condom use among the latter.

Attitudes and Intentions toward Use of HIV Pre-Exposure Prophylaxis (PrEP) among Adults Receiving Treatment for Opioid Use

Background: Although pre-exposure prophylaxis (PrEP) prevents HIV, little is known about PrEP awareness and factors associated with intention to take PrEP among people with opioid use disorder (OUD). Methods: HIV-negative adults recruited from an outpatient treatment program in Cincinnati, Ohio completed self-administered surveys. Items derived from literature and health behavioral theory included demographics, sexual and drug use behaviors, HIV prevention practices, PrEP knowledge, and attitudes toward PrEP. Primary outcomes were 1) intention to ask a clinician about PrEP and 2) intention to accept PrEP if recommended by a clinician. Outcomes were dichotomized into higher vs. lower intention for analyses in logistic regression models. Results: Among 198 participants, 60.3% reported past injection drug use. Among 58 participants (29.3%) meeting criteria for PrEP, 24% were aware of PrEP, 15.5% had discussed it with a clinician, and 5% had taken it. Factors associated with intention to ask a clinician about PrEP included being somewhat confident about consistent condom use (p < 0.01), motivation to comply with normative beliefs (p < 0.01), and reporting that PrEP fits very well (p < 0.01) and is easy to fit (p < 0.01) into current prevention practices. Factors associated with intention to accept PrEP if recommended by a clinician included motivation to comply with normative beliefs (p < 0.01) and PrEP being easy to fit into current prevention practices (p < 0.01). Conclusion: Among participants meeting indications for PrEP, only 24% were aware of it and few had taken it. Interventions that normalize PrEP and target incorporating PrEP into current prevention practices may improve uptake among individuals with OUD.

A mixed methods evaluation assessing the feasibility of implementing a PrEP data dashboard in the Southeastern United States

BACKGROUND

Alabama is one of seven priority states for the National Ending the HIV Epidemic Initiative due to a disproportionate burden of rural infections. To reverse growing infection rates, the state must increase its focus on prevention efforts, including novel strategies. One such approach is to utilize dashboards that visualize real-time data on the pre-exposure prophylaxis (PrEP) care continuum to assist in prioritizing evidence-based preventative care for those most vulnerable for HIV infection.

METHODS

We conducted a mixed methods evaluation to ascertain stakeholders' perceptions on the acceptability, feasibility, appropriateness, and usability of a PrEP care continuum dashboard, as well as gain insight on ways to improve the activities necessary to sustain it. Clinicians, administrators, and data personnel from participating sites in Alabama completed surveys (n = 9) and participated in key informant interviews (n = 10) to better understand their experiences with the prototype data dashboard and to share feedback on how it can be modified to best fit their needs.

RESULTS

Surveys and interviews revealed that all participants find the pilot data dashboard to be an acceptable, feasible, and appropriate intervention for clinic use. Overall, stakeholders find the pilot dashboard to be usable and helpful in administrative efforts, such as report and grant writing; however, additional refining is needed in order to reduce burden and optimize usefulness. Participants voiced concerns about their site's abilities to sustain the dashboard, including the lack of systematized PrEP protocols and limited funds and staff time dedicated to PrEP data collection, cleaning, and upload.

CONCLUSION

Study participants from clinics providing HIV prevention services, including PrEP, in Alabama voiced interest in sustaining and refining a data dashboard that tracks clients across the PrEP care continuum. Despite viewing the platform itself as an acceptable, feasible, and appropriate intervention, participants agreed that efforts need to be focused on standardizing PrEP data collection protocols in order to ensure consistent, accurate data capture and that limited funds and staff time are barriers to the sustained implementation of the dashboard in practice.

Rabies: Epidemiological update and pre- and post-exposure management

Rabies is a deadly neurotropic viral infection but is preventable through vaccination. Its impact on human and animal health is often devastating. Despite advances in research and control of this disease, along with an effective vaccine, rabies continues to be a lingering threat in many parts of the world. Its high incidence reinforces the constant need to address it with scientific and public health measures. In this review article, we will explore the most important characteristics of the disease, its distribution, symptoms, prevention methods, and the global efforts that have been made to eradicate this deadly disease. The most recent research and advancements in the field of rabies will also be discussed in an effort to understand and combat this deadly disease more effectively.

Advancing the community plan to end the HIV Epidemic in Philadelphia: a qualitative descriptive evaluation of low-threshold PrEP services in sexual health clinics

BACKGROUND

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method and a key component of Philadelphia's Community Plan to End the HIV Epidemic (EHE). However, significant barriers to accessing PrEP exist among people at risk for HIV. Low-threshold models for PrEP services that minimize barriers to entry and service engagement could help bolster access to PrEP through community-based clinics. This study aimed to describe the initial implementation of low-threshold PrEP services in three sexual health clinics funded by the Philadelphia Department of Public Health and explore strategies for delivering low-threshold PrEP services.

METHODS

We conducted three focus groups with staff (i.e., providers, prevention navigators, and administrative staff, N = 21) at each of three participating PDPH-funded sexual health clinics from November 2021 to January 2022. Discussion topics included details about the PrEP delivery process, clinic strengths and assets, resource gaps, and PrEP implementation goals. Follow-up interviews with staff members (N = 8) between March 2022 and May 2022 focused on identifying successful strategies for PrEP delivery and adaptations needed to optimize low-threshold PrEP service delivery. Rapid qualitative methods and the Consolidated Framework for Implementation Science were used to analyze data from focus groups and interviews.

RESULTS

Participants collaborated to create process maps that visualized the steps involved in delivering PrEP services within their respective settings. These maps highlighted several stages in PrEP service delivery, such as connecting individuals to services, providing prevention navigation, conducting clinical encounters, and ensuring follow-up care. Participants described effective strategies for implementing PrEP, which included integrating and co-locating services on-site, strengthening staffing resources and capacity, and addressing barriers experienced by clients.

CONCLUSIONS

Lessons from the implementation of low-threshold PrEP service delivery in Philadelphia can guide ongoing local adaptations and future scale-up of these models to improve access to PrEP and advance the goals of the EHE initiative.

Testing the Effectiveness of a Motivational Interviewing Intervention to Reduce HIV Risk and Drug Use in Young Sexual Minority Men in a Community-Based Organization Setting

Younger sexual minority men (YSMM) remain at high risk for HIV infection and substance use increases this risk. This study evaluated the effectiveness of a (4-session) motivational interviewing (MI) intervention to reduce substance use and sexual risk taking when delivered at two community-based organizations (CBOs) in the New York City metropolitan area. Participants included 86 YSMM aged 15-29 who reported recent sexual HIV transmission risk and substance use. Overall, 86% of the sample identified as a racial or ethnic minority. Within each CBO, participants were randomized to receive either the MI intervention or enhanced treatment as usual (an HIV testing session plus PrEP information and referrals to CBO services). Contrary to hypotheses, results provided no indication that the MI intervention was associated with reductions in substance use (alcohol, cannabis, or other illicit drug use) or sexual risk taking or current PrEP use. Results are discussed in terms of challenges in real world intervention implementation, study enrollment, and the COVID-19 pandemic.

[Demographic study of persons living with HIV (PLWH) newly diagnosed in the healthcare area of a tertiary-level hospital]

INTRODUCTION

Countering HIV infection remains a primary objective of the Spanish National Health System. Emergency services play a crucial role in reducing missed diagnostic opportunities, with estimates suggesting that one in 3 such opportunities occur here. The aim of the study is to examine the geographical dispersion of newly diagnosed HIV cases, within a downtown Madrid hospital.

METHODS

This is an observational, descriptive, retrospective study evaluating the geographical distribution of new HIV diagnoses in the care area of a tertiary University Hospital in the Community of Madrid.

RESULTS

Three hundred and eighty-seven individuals with a new diagnosis of HIV infection between 2018 and 2020 were analysed, the majority being young people with an average age of 36±9 years. 86% were gay, bisexual and other men who have sex with men and 48.6% were immigrants. 15.3% presented with CD4+<200cells/mm3 and 9.5% with an AIDS-defining illness. 32.7% and 5.1% had an RNA-HIV-1>100,000copies/mL and >500,000copies/mL, respectively, with up to 13.7% of subjects presenting resistance mutations at diagnosis. Geographically, 51.4% of individuals came from 4 Health Centres and more than 70% of the new diagnoses were included in nine Health Centres.

CONCLUSION

Better understanding the geographical distribution of new HIV diagnoses by health areas allows us to identify areas of higher transmission risk, thereby directing and implementing prevention, early diagnosis, and treatment measures.

Palonosetron versus ondansetron for prophylaxis of postoperative nausea and vomiting in laparoscopic cholecystectomy: a non-inferiority randomized controlled trial

BACKGROUND

We tested the hypothesis that, within the margin of 15% of risk difference, palonosetron is not inferior to ondansetron in reducing the incidence of postoperative nausea and vomiting (PONV) in laparoscopic cholecystectomy.

METHODS

We conducted a double-blind, non-inferiority, randomized, controlled trial of 212 patients aged 18 to 65 years undergoing laparoscopic cholecystectomy under general anesthesia in two secondary care hospitals. Patients were randomly assigned to receive either palonosetron (0.075.ßmg) or ondansetron (8.ßmg) intravenously at induction of anesthesia. Ondansetron (8.ßmg) was also administered 8 and 16.ßhours postoperatively. All anesthetic and surgical procedures were standardized. Patients were evaluated for 24.ßhours postoperatively for the occurrence of PONV.

RESULTS

A high incidence of PONV was observed at 2...6.ßhours postoperatively, with a rate of 36.8% (95% confidence interval [CI] 28.2...46.3) in the palonosetron group, as compared to 43.4% (95% CI 34.4...52.9) in the ondansetron group. The risk difference (95% CI) between palonosetron and ondansetron for PONV was 0 (-10.9 to 10.9) at 0...2.ßhours, -6.6 (-19.4 to 6.5) at 2...6.ßhours, -0.9 (-11.0 to 9.2) at 6...12.ßhours, and -2.8 (-9.6 to 3.6) at 12...24.ßhours. There was no statistically significant difference between the palonosetron and ondansetron groups in the use of rescue medication (dimenhydrinate). There were no adverse events associated with the medications under study.

CONCLUSION

Palonosetron is not inferior to ondansetron in patients at risk of PONV undergoing laparoscopic cholecystectomy, providing a good option for PONV prophylaxis, as it can be administered in a single dose.

Identifying HIV PrEP Attributes to Increase PrEP Use Among Different Groups of Gay, Bisexual, and Other Men Who Have Sex with Men: A Latent Class Analysis of a Discrete Choice Experiment

Daily pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV among gay, bisexual, and other men who have sex with men (GBMSM), although uptake remains suboptimal. By identifying the features of PrEP that appeal to various subgroups of GBMSM, this study aimed to improve PrEP uptake by examining preferences for PrEP use. Adults ≥ 18 years old in six New England states completed an online discrete choice experiment survey. A latent class analysis (LCA) was conducted to identify groups of GBMSM based on four attributes of choices for PrEP (cost, time, side effects, and mode of administration). Multinominal logistic regression was conducted to compare the association between sociodemographic and behavioral characteristics and class memberships. Data from 675 GBMSM were analyzed. A 3-Class model was selected as the best fit model. Class 1 (47.7% of individuals) was identified as having "no specific preferences". Class 2 (18.5% of individuals) were "Cost- and time-conscious" and were significantly more likely to be older, have prior sexually transmitted infection (STI) testing, have low household income, private insurance, and have extreme concerns about HIV risk than those with no specific preference (Class 1). Finally, Class 3 (34.1% of individuals) were "Side effects-conscious" and were more likely to have low income, private insurance, and have moderate and extreme concerns about HIV risk than those with no specific preference (Class 1). Findings indicate that outreach to GBMSM who have never used PrEP should emphasize low cost and short travel times to increase potential PrEP use.

A First-in-Human Randomized Study to Assess the Safety, Tolerability, Pharmacokinetics, and Neutralization Profile of Two Investigational Long-Acting Anti-SARS-CoV-2 Monoclonal Antibodies

INTRODUCTION

COVID-19 remains a significant risk for the immunocompromised given their lower responsiveness to vaccination or infection. Therefore, passive immunity through long-acting monoclonal antibodies (mAbs) offers a needed approach for pre-exposure prophylaxis (PrEP). Our study evaluated safety, anti-SARS-CoV-2 neutralizing activity, nasal penetration, and pharmacokinetics (PK) of two half-life-extended investigational mAbs, AER001 and AER002, providing the first demonstration of upper airway penetration of mAbs with the LS-modification.

METHODS

This randomized, double-blind, placebo-controlled phase I study enrolled healthy adults (n = 80) who received two long-acting COVID mAbs (AER001 and AER002), AER002 alone, or placebo. The dose ranged from 100 mg (mg) to 1200 mg per mAb component. The primary objective was to describe the safety and tolerability following intravenous (IV) administration. Secondary objectives were to describe PK, anti-drug antibodies (ADA), neutralization activity levels, and safety evaluation through 6 months of follow-up.

RESULTS

The majority (97.6%) of the reported adverse events (AE) post administration were of grade 1 severity. There were no serious adverse events (SAE) or ADAs. AER001 and AER002 successfully achieved an extended half-life of 105 days and 97.5 days, respectively. Participants receiving AER001 and AER002 (300 mg each) or AER002 (300 mg) alone showed 15- and 26-fold higher neutralization levels against D614G and omicron BA.1 than the placebo group 24 h post-administration. Single 300 or 1200 mg IV dose of AER001 and AER002 resulted in nasal mucosa transudation of approximately 2.5% and 2.7%, respectively.

CONCLUSION

AER001 and AER002 showed an acceptable safety profile and extended half-life. High serum neutralization activity was observed against D614G and Omicron BA.1 compared to the placebo group. These data support that LS-modified mAbs can achieve durability, safety, potency, and upper airway tissue penetration and will guide the development of the next generation of mAbs for COVID-19 prevention and treatment.

Low daily oral PrEP adherence and low validity of self-report in a randomized trial among PWID in Ukraine

BACKGROUND

The efficacy of daily oral pre-exposure prophylaxis (PrEP) in preventing HIV transmission among people who inject drugs (PWID) was demonstrated over a decade ago. However, only a few studies among PWID have since measured PrEP adherence using laboratory markers.

METHODS

In this trial, we randomized recently injecting PWID in Kyiv, Ukraine, to receive daily oral TDF/FTC with or without SMS reminders. Enrollment and PrEP initiation took place at an HIV clinic. Subsequent visits at months 1, 3, and 6 were conducted at a community harm reduction center and included a structured interview, adherence counseling, PrEP dispensing, and dried blood spot collection. PrEP adherence was assessed using standard self-reported measures and TDF/FTC biomarkers.

RESULTS

A total of 199 PWID (99 SMS, 100 No-SMS) were enrolled, of whom 24 % were women, with a median age of 37. At month 6, 79.4 % (158/199) of participants were retained, with 84 % (133/158) reporting opioid injection and 20 % (31/158) reporting stimulant injection in the past 30 days. 77 % (122/158) reported taking >95 % of PrEP doses in the past month, and 87 % reported taking the last dose within 2 days. Tenofovir diphosphate was detected in 17 % (28/158) of participants, and emtricitabine triphosphate was detected in 25 % (40/158). Only 3 % (5/158) had metabolite levels indicative of consistent PrEP uptake at 4+ doses per week. There was no association between the SMS intervention and TDF/FTC metabolite detection.

CONCLUSION

Adherence to daily oral PrEP among actively injecting PWID, without daily supervision or incentives, was extremely low, despite supportive counseling and SMS reminders. We also observed a high rate of discordance between self-report and classification by a validated biomarker of adherence. Given the scarcity of evidence and emerging data suggesting low oral PrEP adherence among PWID, additional implementation studies with TDF/FTC biomarkers are needed to study whether a sufficient level of adherence to daily PrEP is attainable among PWID, especially as long-acting injectable PrEP offers a promising alternative.

Beyond HIV prevention: Assessment of the benefits of pre-exposure prophylaxis for sexual quality of life

BACKGROUND

Pre-exposure prophylaxis (PrEP) may favor sexual satisfaction by reducing the fear of HIV and promoting less restrictive sexual practices. These benefits may be even higher among PrEP users with mental health issues.

METHODS

We invited adult PrEP users to answer a questionnaire including demographics, questions on the sexual experience compared to the period before PrEP use, and the Hospital Anxiety and Depression Scale. Factors associated with improvements in the sexual experience were investigated using modified Poisson models.

RESULTS

We included 221 participants; most were white males. A large percentage of participants reported improvements in quality of sex after PrEP initiation; the composite outcome "PrEP-associated improvement in the quality of sex" was observed in 92 (42%), whereas the outcome "PrEP-associated improvement in the fear of HIV acquisition" was observed in 120 participants (54%). Demographics and depression/anxiety were not significantly associated with the outcomes.

CONCLUSION

PrEP has positive effects beyond HIV prevention, improving several aspects of sexual quality of life. These benefits are valid incentives for PrEP use and prescription.

Lack of evidence of acute HEV infections as a sexually transmitted disease: Data from a German cohort of PrEP users

BACKGROUND

While the sexual transmissibility of HAV in MSM has been extensively described, the potential for sexual transmission of HEV has not been definitively established. Although HEV has been detected in the ejaculate of chronically infected men, studies among MSM PrEP users in France did not observe an elevated anti-HEV seroprevalence as an indicator of increased exposure risk by sexual intercourse.

PATIENTS AND METHODS

A total of 111 unselected PrEP users and 111 age- and sex-matched blood donors were tested for anti-HEV IgG, IgM and HEV (PCR). Of the participants 79/111 (71 %) responded to a questionnaire covering topics as sexual preferences, previous sexually transmitted diseases, profession, food consumption, and pet ownership.

RESULTS

The anti-HEV IgG seroprevalence in PrEP users (22 %) did not differ significantly from the rate in controls (17 %). While one PrEP user and three controls tested positive for anti-HEV IgM, all PrEP users and controls tested PCR negative.

CONCLUSION

In immunocompetent individuals with frequent changes of sexual partners, the epidemiology of Hepatitis E Virus does not significantly involve the sexual transmission route.

Pre-exposure Prophylaxis Adherence Among Men Who Have Sex With Men: A Systematic Review and Meta-analysis

OBJECTIVES

The effectiveness and efficiency of pre-exposure prophylaxis (PrEP) in reducing the transmission of human immunodeficiency virus (HIV) among men who have sex with men (MSM) relies on how widely it is adopted and adhered to, particularly among high-risk groups of MSM. The meta-analysis aimed to collect and analyze existing evidence on various factors related to PrEP adherence in MSM, including demographic characteristics, sexual behaviors, substance use, and psychosocial factors.

METHODS

The meta-analysis followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The search included articles published between January 2018 and December 2022, obtained from the PubMed, ScienceDirect, and Scopus databases. The studies that were included in the analysis reported the proportion of MSM who demonstrated adherence to PrEP and underwent quality appraisal using the Newcastle-Ottawa Scale.

RESULTS

Of the 268 studies initially identified, only 12 met the inclusion criteria and were included in the final meta-analysis. The findings indicated that education (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.12 to 2.40), number of sexual partners (OR, 1.16; 95% CI, 1.02 to 1.31), engaging in sexual activities with an human immunodeficiency virus-positive partner (OR, 1.59; 95% CI, 1.16 to 2.26), substance use (OR, 0.83; 95% CI, 0.70 to 0.99), and lower levels of depression (OR, 0.55; 95% CI, 0.37 to 0.82) were associated with higher rates of PrEP adherence among MSM.

CONCLUSIONS

Despite these findings, further research is necessary to investigate PrEP adherence more comprehensively. The findings of this meta-analysis can be utilized to inform interventions aimed at improving PrEP adherence among MSM and provide directions for future research in this area.

Factors Associated with Planned Future Use of PrEP in the Next 3 Months and Likelihood to Use PrEP Among Black Cisgender HIV-negative Women in Texas

Identifying and then addressing barriers and leveraging facilitators is important to help increase pre-exposure prophylaxis (PrEP) use among Black women vulnerable to HIV acquisition. The present cross-sectional study examined what factors were associated with future plans to use PrEP, and general likelihood to use it among a convenience sample of 152 adult, Black cisgender women from three metropolitan areas in Texas. The final multivariable logistic regression model revealed that relationship status (aOR = 0.20, 95% CI: 0.05-0.73, p < 0.05), PrEP anticipated stigma (aOR = 0.29, 95% CI: 0.10-0.78, p < 0.05), perceived discrimination (aOR = 0.40, 95% CI: 0.21-0.78, p < 0.01) and interest in learning more about PrEP (aOR = 5.32, 95% CI: 2.60-10.9, p < 0.001) were associated with future plans to use PrEP. The final multivariable linear regression model with maximum likelihood estimation identified that perceived discrimination (β=-0.24, SE: -0.38 - -0.10, p < 0.01), perceived HIV risk (β = 0.33, SE: 0.18-0.49, p < 0.001), willingness to use PrEP with condoms (β = 1.26, SE: 0.94-1.60, p < 0.001), and comfort communicating about PrEP with a provider (β = 0.23, SE: 0.06-0.41, p < 0.01) were associated with general likelihood to use PrEP. Findings reveal key factors that warrant further attention and examination toward improving PrEP use within this population.

Feasibility and acceptability of peer-delivered interventions using mHealth for PrEP services among adolescent girls and young women in DREAMS program in Botswana

BACKGROUND

Adolescent girls and young women accounted for 25% of all new HIV infections despite representing only 10% of the population in Sub Saharan Africa. PEPFAR has launched the Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe (DREAMS) initiative, a comprehensive HIV prevention program including PrEP services. Among adolescent girls and young women, PrEP adherence is currently sub-optimal. Tailored strategies for adolescent girls and young women to improve access and use of PrEP delivery are urgently needed to maximise its potential. Recommended interventions include peer-delivered interventions using mobile technology. However, data on the feasibility and acceptability of this approach is limited for SSA.

OBJECTIVES

We assessed the feasibility and perceived acceptability of providing mHealth peer-delivered interventions to support PrEP services among adolescent girls and young women in Botswana.

METHODS

This cross-sectional study included HIV-negative women aged 18-24 years old seeking health services at DREAMS-supported facilities. Participants completed a survey assessing the feasibility and perceived acceptability of the mHealth peer-delivered interventions, which included the Acceptability of Intervention Measure (AIM). Descriptive analyses were performed.

RESULTS

A total of 131 participated in the study. Overall, 89% owned a mobile phone (feasibility). There was no difference in cell phone ownership between participants from rural and urban settings. Among participants, 85% reported interest in participating in a mHealth peer-delivered intervention if it was available to them. Regarding perceived acceptability for mHealthpeer support groups for PrEP, the average score on the AIM was 3.8 out of 5 (SD = 0.8).

CONCLUSION

mHealthpeer-delivered interventions appear to be feasible and perceived acceptable among adolescent girls and young women in Botswana. This modality should be incorporated into PEPFAR's programmatic toolkit of implementation strategies to improve PrEP services.

[Tropical sexually transmitted infections Summary of the SFMTSI Scientific Day of November 9, 2023]

Sexually transmitted infections (STIs) deserve more attention today than ever in the tropics. Indeed, the emergence of monkeypox in 2022 in Western countries reminds the risk of exporting STIs from the tropics as it was already known for decades with the worldwide spread of HIV/AIDS infection from tropical Africa. Some hazards are already well identified. According to WHO 2023 report STIs are increasing in the world. Antibiotic resistance is increasing for Neisseria gonorrhoeae, and already well established for Mycoplasma genitalium, whereas Treponema pallidum has become resistant to macrolides within the last twenty years. Some neglected tropical diseases (Zika, Ebola, monkeypox) can also be sexually transmitted, sometimes months after cure (Ebola). In this setting, the use of PrEP in migrants, and in Africa, is worth to be discussed beyond traditional circles.

Pre-exposure prophylaxis of non-HIV viral infections and the role of long-acting antivirals

Viruses cause a large burden of human infectious diseases. During the past 50 years, antivirals have been developed to treat many pathogenic viruses, including herpesviruses, retroviruses, hepatitis viruses, and influenza. Besides being used as treatment, antivirals have shown efficacy for preventing certain viral infections. Following the success in the HIV field, a renewed interest has emerged on the use of antivirals as prophylaxis for other viruses. The development of formulations with extended half-life has pushed further this consideration in persons at risk for a wide range of viral infections. In this way, long-acting antivirals might behave as "chemovaccines" when classical vaccines do not exist, cannot be recommended, immune responses are suboptimal, escape mutants emerge, and/or immunity wanes. Five main caveats would temper its use, namely, selection of drug resistance, drug interactions, short- and long-term side effects, potential teratogenicity in women of child-bearing age, and high cost. Herein, we discuss the prospects for long-acting antivirals as prophylaxis of human viral infections other than HIV.

Willingness to take long-acting injectable pre-exposure prophylaxis among men who have sex with men who participated in the CROPrEP study: a cross-sectional online study

INTRODUCTION

Evidence on the willingness of men who have sex with men (MSM) with oral pre-exposure prophylaxis (PrEP) experience, especially those with suboptimal adherence, to take long-acting injectable PrEP (LAI-PrEP) is critical to guide future LAI-PrEP implementation.

OBJECTIVE

The objective was to assess the willingness of MSM with oral PrEP experience to take LAI-PrEP.

METHODS

MSM who participated in the China Real-world Study of Oral PrEP (CROPrEP) were enrolled in this study. Information on the willingness of MSM to take LAI-PrEP and potential correlates was collected using a structured online questionnaire. The main outcomes were the willingness of MSM to take LAI-PrEP and its association with HIV-related behaviours, sexually transmitted infections, and oral PrEP history. Logistic regression was used to identify correlates of the willingness of MSM to take LAI-PrEP.

RESULTS

A total of 612 former CROPrEP participants (FCPs) were included in this study. There were 315 (51.5%) daily oral PrEP (D-PrEP) users and 297 (48.5%) event-driven oral PrEP (ED-PrEP) users at the last follow-up. Most FCPs (77.8%) were willing to take free LAI-PrEP. FCPs with no less than two sexual male partners (aOR = 1.54, [95% CI: 1.04, 2.29], P = 0.031), those with male partners with unknown HIV statuses (aOR = 2.04, [95% CI: 1.31, 3.18], P = 0.002), those with recreational drug use (aOR = 1.58, [95% CI: 1.05, 2.40], P = 0.030), and those with HSV-2 positivity (aOR = 2.15, [95% CI: 1.30, 3.57], P = 0.003) were more willing to take LAI-PrEP, while ED-PrEP users (aOR = 0.66, [95% CI: 0.45, 0.98], P = 0.037) and FCPs with suboptimal oral PrEP adherence (aOR = 0.58, [95% CI: 0.36, 0.94], P = 0.026) were less willing to take LAI-PrEP.

CONCLUSION

LAI-PrEP has good prospects for expanding PrEP coverage. However, FCPs with suboptimal oral PrEP adherence are less likely to take LAI-PrEP. Further intervention and implementation efforts are needed to improve the willingness of MSM to use LAI-PrEP, and sexual health should be considered during the discussion about PrEP initiation.

A latent trajectory analysis of young sexual and gender minorities' adherence to three rectal microbicide placebo formulations (MTN-035; a randomized crossover trial)

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.

Patterns of HIV Pre-exposure Prophylaxis use Among Adolescent Girls and Young Women Accessing Routine Sexual and Reproductive Health services in South Africa

PURPOSE

This study describes the patterns of pre-exposure prophylaxis (PrEP) use among adolescent girls and young women (AGYW) initiated on daily oral PrEP for the prevention of HIV, within routine sexual and reproductive health services in South Africa.

METHODS

We analysed clinical and survey data from a nested cohort of 967 AGYW initiated on oral PrEP between January 2019 and December 2021 in four geographical clusters in South Africa. We describe the periods of PrEP use, and the proportion who discontinued and subsequently restarted PrEP. Logistic regression analyses were conducted to determine factors associated with early PrEP discontinuation, PrEP use for ≥4 months and PrEP restart.

RESULTS

PrEP use for ≤1 month was high (68.6%), although 27% returned and restarted PrEP; and 9% restarted more than once. Initiating PrEP at a mobile clinic (AOR 2.10, 95% CI 1.51 - 2.93) and having a partner known to be HIV negative or whose HIV status was unknown (AOR 7.11, 95% CI 1.45 - 34.23; AOR 6.90, 95% CI 1.44 - 33.09) were associated with PrEP use for ≤1 month. AGYW receiving injectable contraceptives were more likely to restart PrEP (AOR 1.61, 95% CI 1.10 - 2.35). Compared to those aged 15-17 years, participants 18 - 20 and 21 - 24 years were less likely to restart PrEP (AOR 0.51, 95% CI 0.35 - 0.74; AOR 0.60, 95%, CI 0.41 - 0.87), as were those initiating PrEP at a mobile clinic compared to a fixed facility (AOR 0.66, 95% CI 0.47 - 0.92).

DISCUSSION

Although early PrEP discontinuation was high, it appears that PrEP use is frequently cyclical in nature. Further research is needed to determine if these cycles of PrEP correlate to periods of perceived or actual vulnerability to HIV, which may also be cyclical. PrEP delivery presents a unique opportunity to address multiple unmet health needs of young people.

Digital Interventions to Enhance PrEP Uptake and Adherence Through Stigma Reduction

PURPOSE OF REVIEW

Although pre-exposure prophylaxis (PrEP) is effective for reducing risk of HIV transmission, stigma persists as a barrier to HIV prevention. Digital technologies present opportunities to access hard-to-reach populations and increase the efficiency of established interventions. This review examines current digital interventions addressing stigma to improve PrEP-related outcomes.

RECENT FINDINGS

Digital technologies are increasingly used for HIV prevention and include a wide range of formats. Recent interventions focused on stigma and PrEP tend to engage mobile phone-related technology and focus on younger populations with particular attention to men who have sex with men and transgender women. Digital interventions that address stigma are promising for improving PrEP-related outcomes. No single technology currently demonstrates consistent superiority. Limited access to PrEP and heightened stigma in under-resourced countries present challenges for interventions supporting diverse communities. Further research should examine how digital interventions can reduce stigma beyond the individual level to enhance PrEP use and explore opportunities to improve and integrate approaches to stigma measurement.

When Ethics and the Law Collide: A Multicenter Demonstration Cohort Study of Pre-Exposure Prophylaxis Provision to Adolescent Men Who Have Sex With Men and Transgender Women in Brazil

PURPOSE

To explore legal and ethical challenges related to adolescents' participation in human immunodeficiency virus (HIV) research that may affect their best interests.

METHODS

We analyzed the ethical principles and legal aspects of the participation of 15-17-year-old men who have sex with men and transgender women in the pre-exposure prophylaxis (PrEP) 1519 study, a PrEP demonstration cohort study in three Brazilian cities. The analyses of ethics review committees' (ERCs) evaluations and court decisions followed ethical and human rights principles. An HIV vulnerability score was created, and descriptive statistics and multivariate logistic regression were performed using data from 347 participants.

RESULTS

The ERCs evaluated the benefits and risks of research participation, all finding that the benefits outweighed the risks. ERCs deferred responsibility for decisions about waiving parental consent to the judiciary. State courts reached different decisions about waiving parental consent, reflecting variation in recognition of adolescents' evolving capacities and the adolescent as a subject of sexual rights and the primary agent capable of deciding on their health and best interests. The most vulnerable adolescent participants were found in sites where the blanket waiver was in place.

DISCUSSION

Judicializing the ethical review process is detrimental to fulfilling the ethical principle of justice and vulnerable adolescents' access to health research. ERCs must be sufficiently independent and autonomous and have the capacity to respect, protect, and help fulfill the rights of participants while ensuring the generation of adequate evidence to inform public health practice.

Acceptability and Effectiveness of a One-Hour Healthcare Provider Intervention Integrating HIV Pre-Exposure Prophylaxis and Cultural Competence Training

Enhanced provider training could improve PrEP access and equity. We conducted a pilot randomized controlled trial comparing (a) a one-hour, group-based provider intervention integrating PrEP and Cultural Competence (PCC) training with (b) a standard HIV continuing medical education session (n = 56). PCC participants favorably rated the intervention and reported increased PrEP knowledge. The PCC intervention increased their confidence performing PrEP-related clinical activities and intention to prescribe PrEP. The percentage of participants discussing PrEP with patients increased marginally in both study conditions. The percentage of participants who prescribed PrEP and self-rated cultural competence did not change in either study condition.

Assessing the Preliminary Efficacy of a Nonrandomized, Clinic-Based HIV Risk Reduction Pilot Intervention for PrEP-Initiated, Alcohol- and Other Drug-Using Women of Color in Miami, FL

In this paper, we assessed the preliminary efficacy and acceptability of a quasi-experimental, clinic-based sexual risk reduction pilot intervention for pre-exposure prophylaxis (PrEP)-initiated, alcohol- and other drug-using women of color and explored their self-reported barriers to, and facilitators of, PrEP use. Using a mixed methods design, analyses incorporated pre- and post-intervention study assessment data from 38 women and semi-structured process evaluations using a subsample of 25. The intervention administered over an 8-week period consisted of 4 one-on-one in person educational sessions, a process evaluation, and study assessments conducted at baseline and 3 and 6 months. Post intervention, statistically significant changes in sexual risk scores were not observed; however, we found significant decreases in alcohol use (Z =  - 3.02, p = .003, η2 = .41). Process evaluation data revealed interpersonal relationships as a key motivator for PrEP initiation as well as a prominent barrier to PrEP use; these relationships rarely facilitated adherence. Overall, women found the intervention to be acceptable and reported a wide range of benefits of participation-most notably its therapeutic benefits. Findings from this study provide preliminary evidence of the potential for the Talking PrEP with Women of Color intervention to improve risky behaviors, knowledge, and attitudes related to sexual risk taking. Furthermore, findings suggest that interventions to increase PrEP uptake and adherence in at-risk women may benefit from supporting them in accurately estimating their risk for HIV and increasing their sense of social support.
