Contraceptive decision-making is highly complex, and family planning (FP) clients choose methods according to a host of personal, interpersonal, and context-specific considerations. These include concerns about side effects, confidence in their ability to adhere to daily or monthly use, efficacy of methods, partner support, and HIV vulnerability. FP decision support tools can support FP clients and providers to engage in a joint decision-making process to ensure clients make informed choices about contraception. For more than two decades, the Balanced Counseling Strategy (BCS) and Balanced Counseling Strategy Plus (BCS+) decision support tools have been used in lower- and middle-income countries, informed by implementation science research and iterative updates and refinements to reflect new developments in contraceptive technology and HIV prevention strategies. To inform the development and scale-up of future FP decision support tools, as well as share lessons from translating implementation science results to practice, this article describes the development, evaluation, and proliferation of BCS and BCS+.

Background In many parts of the world, including Brazil, uptake for biomedical interventions has been insufficient to reverse the HIV epidemic among key populations at high risk for HIV, including men who have sex with men. Young MSM (YMSM), particularly Black YMSM, have high HIV incidence, low viral suppression, and low preexposure prophylaxis (PrEP) uptake and adherence. Therefore, novel approaches to increase the HIV biomedical interventions uptake by YMSM are urgently needed. Objective We describe the Conectad@s Project, which aims to: (1) estimate the prevalence and incidence of HIV and other sexually transmitted infections, the onset of sexual risk behavior, and barriers to biomedical interventions among YMSM aged 18 to 24 years in Rio de Janeiro, Brazil; and (2) conduct a technology-based adherence intervention study to promote a rapid linkage of YMSM to HIV care or prevention, and support and sustain adherence. Methods A cross-sectional survey will be conducted with 400 YMSM recruited using respondent-driven sampling (RDS) adapted for social media-based sampling, preceded by a formative phase. HIV and sexually transmitted infections testing will be conducted, including early HIV infection biomarker detection. Behavioral, partnership, network, and structural measures will be collected through structured questionnaires. All individuals recruited for the survey will have access to HIV risk assessment, antiretroviral therapy (ART), PrEP, prevention counseling, and a technology-based adherence intervention. Those who accept the adherence intervention will receive weekly text messages via a social networking app (WhatsApp) for 24 weeks, with follow-up data collected over 48 weeks. Results The Conectad@s project has been approved by our local institutional review board (#CAAE 26086719.0.0000.4262) in accordance with all applicable regulations. Questionnaires for the RDS survey and intervention were developed and tested in 2020, formative interviews were conducted in January and February 2021 to guide the development of the RDS, and enrollment is planned to begin in early 2022. Conclusions The Conectad@s Project is a vanguard study that, for the first time, will apply digital RDS to sample and recruit YMSM in Brazil and rapidly connect them to ART, PrEP, or prevention counseling through a technology-based adherence intervention. RDS will allow us to estimate HIV prevalence among YMSM and measure HIV infection biomarkers in the context of the onset of risky behavior. The data will lay the groundwork to adapt and implement HIV prevention strategies, identify barriers to the earliest HIV infection diagnosis, immediate ART or PrEP initiation, and detect new clusters of HIV transmission.

Introduction Knowing the factors associated with HIV transmission is necessary in order to design preventive programmes tailored to the epidemiological situation in each region and population. Aim Our objective was to study the sociodemographic, clinical and behavioural characteristics of men who have sex with men (MSM) who were newly diagnosed with HIV infection. Methods We carried out an observational, descriptive, study on all MSM newly diagnosed with HIV infection in one clinic for sexually transmitted infections (STI) and HIV clinic in Madrid between 2014 and 2019. Information on sociodemographic, clinical, and behavioural characteristics of participants per year of diagnosis was collected. Results We detected a total of 1,398 people with HIV infection, 253 of whom were recent seroconverters (rSCV) with a median duration of documented seroconversion of 6 months. From the total, 97.9% infections were sexually transmitted and 2.1% involved injected drugs, i.e. slam practices. The average age was 32.9 years (range: 15.6–74.9), 51.8% were Spanish and 40% Latin American. These diagnoses decreased in Spanish people and increased in Latin Americans during the study period. Of the rSCV, 73.9% had condomless sex under the influence of drugs and 28.9% participated in chemsex sessions. Apps were used by 92.6% rSCV for sexual encounters and 70.4% of them attributed HIV transmission to their use. Conclusions Combination of HIV prevention strategies, as pre-exposure prophylaxis, should be reinforced among young MSM, especially those born in Latin America, those who use drugs for sex, and those who use apps in search of sexual contacts.

Thirty-five years since the discovery of the human immunodeficiency virus (HIV), the epidemic is still ongoing in France. To guide HIV prevention strategies and monitor their impact, it is essential to understand the dynamics of the HIV epidemic. The indicator for reporting the progress of new infections is the HIV incidence. Given that HIV is mainly transmitted by undiagnosed individuals and that earlier treatment leads to less HIV transmission, it is essential to know the number of infected people unaware of their HIV-positive status as well as the time between infection and diagnosis. Our approach is based on a non-homogeneous multi-state Markov model describing the progression of the HIV disease. We propose a penalized likelihood approach to estimate the HIV incidence curve as well as the diagnosis rates. The HIV incidence curve was approximated using cubic M-splines, while an approximation of the cross-validation criterion was used to estimate the smoothing parameter. In a simulation study, we evaluate the performance of the model for reconstructing the HIV incidence curve and diagnosis rates. The method is illustrated in the population of men who have sex with men using HIV surveillance data collected by the French Institute for Public Health Surveillance since 2004.

We triangulated quantitative and qualitative assessments to evaluate participants’ acceptability of 0.05% dapivirine rectal microbicide (RM) gel administered via two separate modalities (a rectal applicator and an artificial phallus for use as a coital simulation device) as part of a Phase I trial (N = 14) among men who have sex with men (MSM) randomized using a 1:1 ratio. Overall, participants reported favorable acceptability of the gel (n = 11; 78.6%), the same or more at the end of the study compared to when they started the study. Additionally, when discussing their preferred administration modality, they noted that both methods had positive qualities but also potential areas of improvement. Our findings underscore the need to create multiple delivery methods for a future microbicide gel (i.e., with and without the need for an applicator) and highlight the importance of offering MSM choices in how biomedical HIV prevention strategies are delivered.

The spread of HIV in Europe is still ongoing. The established HIV prevention strategies base on structured goals to promote a behavior preventing HIV transmission, complemented by the provision of antiretroviral treatment. If followed by those people concerned, these multifactorial prevention strategies should encourage individual behavior that avoids HIV transmission in various ways, supplemented by medical help for people who are already HIV-infected. Both national and international institutions have pointed to those who present late after being infected with HIV, the undiagnosed late presenters – who unknowingly may contribute to the spread of HIV. There are already initiatives for adjustments to the prevention strategies. In this context, reference is made to the burdens on societies. In addition to the established prevention strategies, we propose the introduction of contact tracing. This measure could help reach and support people of the officially defined key populations to obey the prevention measures. This array might have a synergetic effect to contain the spread of HIV, thereby reducing the burden for societies. A juridical analysis clarifies the handling of the term discrimination. Discrimination begins where a person is penalized because they are infected or ill. However, anyone who intentionally or negligently transmits HIV to unknowing people damages a person's health and this person is therefore also held criminally responsible in all legal systems. The so-called anti-discrimination concepts in the field of criminal law must not lose sight of this distinction.

AbstractAround the world, geosocial networking apps have become widely popular among sexual minority men (SMM). This research analyzed the sexual behaviors and HIV and STI prevention strategies (HIV/STI testing, HIV/STI inquiry, and HIV/STI disclosure) of an online-recruited sample of 284 SMM living in Ecuador. Sexting and oral sex were the most common sexual behaviors among SMM in the sample. Most participants had low perceptions of HIV and STI risk; 85% reported being tested for HIV and 70% for STIs. Being older predicted higher odds of being tested for either HIV or STIs at least once. Being single also predicted HIV testing. Future interventions in the country should explore apps’ utility as intervention tools to spread information about sexual health and HIV prevention strategies, such as condom use and event-driven PrEP. Apps can also facilitate connections to sexual health services, including programs for PrEP initiation and linkage to HIV treatment. They should also focus on promoting sexual harm reduction conversations among potential app-met sexual partners.

Socioeconomic inequality is a major factor to consider in the prevention of human immunodeficiency virus (HIV) transmission. The aim of this study was to investigate socioeconomic inequalities in HIV prevalence among Namibian women. Data from a population-based household survey with multistage-stratified sample of 6501 women were used to examine the link between socioeconomic inequalities and HIV prevalence. The weighted HIV prevalence was 13.2% (95% CI: 12.1–14.3%). The HIV prevalence among the poorest, poorer, middle, richer, and richest households was 21.4%, 19.7%, 16.3%, 11.0%, and 3.7%, respectively. Similarly, 21.2%, 21.7%, 11.8%, and 2.1% HIV prevalence was estimated among women with no formal education and primary, secondary, and higher education, respectively. Women from poor households (Conc. Index = −0.258; SE = 0.017) and those with no formal education (Conc. Index = −0.199; SE = 0.015) had high concentration of HIV infection, respectively. In light of these findings, HIV prevention strategies must be tailored to the specific drivers of transmission in low socioeconomic groups, with special attention paid to the vulnerabilities faced by women and the dynamic and contextual nature of the relationship between socioeconomic status and HIV infection.
