A protocol for a randomized controlled trial of couples motivational interviewing to reduce drug use and HIV transmission risk among male couples in the US: the Couples Health Project.

Background: To reduce substance use and sexual HIV transmission risk among sexual minority men (SMM) requires the development of interventions tailored for those in relationships. In the past 5 years, there have been considerable advances in the development of motivational nterviewing (MI) with couples. The Couples Health Project (CHP) is the first multi-session risk reduction protocol built on this formative research.

Comparing Repeated (Annual) Couples HIV Testing and Counseling to Individual HIV Testing and Counseling Among Male Couples at High Risk of HIV Infection: Protocol for a Randomized Control Trial.

Background: Couples HIV testing and counseling (CHTC) is now a standard of care prevention strategy recommended by the Centers for Disease Control and Prevention for sexual minority men (SMM) in relationships. Despite standard recommendations that couples complete CHTC every 6-12 months, no study has empirically evaluated the effects associated with CHTC retesting.

Objective: This study aims to understand the benefits associated with continued dyadic engagement in the HIV prevention continuum through routine CHTC retesting, which is of particular importance for emerging-adult SMM in relationships who use drugs.

Drug use during the second year of the COVID-19 pandemic: observations from repeated cross-sectional surveys of sexual minority men in the US active on social networking applications.

Studies conducted early in the COVID-19 pandemic - before vaccines were widely available - indicated that drug use may have declined among sexual minority men (SMM). This study evaluated drug use trends in the second year of the pandemic. Cross-sectional responses from cisgender SMM living in the US and recruited online (= 15,897) were grouped for analyses: Time 1: 3/1/2021-5/30/2021; Time 2: 6/1/2021-8/31/2021; Time 3: 9/1/2021-11/30/2021; and Time 4: 12/1 2021-2/28/2022.

Communicating climate change and biodiversity loss with local populations: exploring communicative utopias in eight transdisciplinary case studies.

Climate change and biodiversity loss trigger policies targeting and impacting local communities worldwide. However, research and policy implementation often fail to sufficiently consider community responses and to involve them. We present the results of a collective self-assessment exercise for eight case studies of communications with regard to climate change or biodiversity loss between project teams and local communities.

Assessment of the effect of short-term weathering on the molecular-level chemical composition of crude oils in contact with aquatic environments.

Multiple studies have focused on the effect of long-term weathering processes on oils after spill events, without considering the chemical compositional changes occurring shortly after the release of oil into the environment. Therefore, the present study provides a broad chemical characterization for understanding of the changes occurring in the chemical compositions of intermediate (°API = 27.0) and heavy (°API = 20.
