A cross-sectional survey of potential factors, motivations, and barriers influencing research participation and retention among people who use drugs in the rural USA.

Background: Despite high morbidity and mortality among people who use drugs (PWUD) in rural America, most research is conducted within urban areas. Our objective was to describe influencing factors, motivations, and barriers to research participation and retention among rural PWUD.

Methods: We recruited 255 eligible participants from community outreach and community-based, epidemiologic research cohorts from April to July 2019 to participate in a cross-sectional survey.

The Relationship Between Hepatitis C Virus Rates and Office-Based Buprenorphine Access in Ohio.

Background: The United States is experiencing an epidemic of hepatitis C virus (HCV) infections due to injection drug use, primarily of opioids and predominantly in rural areas. Buprenorphine, a medication for opioid use disorder, may indirectly prevent HCV transmission. We assessed the relationship of HCV rates and office-based buprenorphine prescribing in Ohio.

Alcohol abstinence stigma and alcohol use among HIV patients in Thai Nguyen, Vietnam.

Background: Hazardous alcohol use is prevalent among people living with HIV (PWH), leading to sub-optimal HIV treatment outcomes. In Vietnam, alcohol use is highly normative making it socially challenging for PWH to reduce or abstain. We used mixed methods to develop a quantitative scale to assess alcohol abstinence stigma and examined the association between alcohol abstinence stigma with alcohol use among PWH in Vietnam.

Substance use and universal access to HIV testing and treatment in sub-Saharan Africa: implications and research priorities.

As universal testing and treatment for HIV, or 'treat all', expands across sub-Saharan Africa (SSA), substance use will likely have a negative impact on the success of scale-up efforts for antiretroviral treatment (ART). Overwhelming evidence highlights the negative impact of substance use on HIV care and treatment outcomes. Yet, as many countries in SSA expand ART, evidence of the extent of substance use, and its impact in the region, is more limited.
