Recovery Capital in Patients Receiving Methadone Maintenance Treatment Who Use Methamphetamine in Vietnam
Open AccessLuan Thanh Pham, Huyen Pham et al.ARTICLESubstance Use & Misuse2026
Background: Recovery from substance use disorder may require various types of support to address complex needs. Recovery capital (RC), a measure of resources aiding recovery, could play a vital role in determining recovery outcomes. This study explored RC and related factors in patients on methadone maintenance treatment (MMT) who also use methamphetamine. Methods: We conducted a cross-sectional study in December 2023 with 50 participants from a …
Patient Trust in Healthcare Providers among People on Methadone Maintenance Treatment Using Methamphetamine in Vietnam
Minh Anh Vu, Diep Bich Nguyen et al.ARTICLESubstance Use & Misuse2026
Introduction Patient trust in healthcare providers (PTP) is critical for improving treatment adherence and outcomes in substance use disorders.

Multi-method Analysis of Implementation Determinants and Strategies to Support the Implementation of Contingency Management for Methamphetamine Use in an HIV Care Setting
Open AccessMaximo Prescott, Victoria Chentsova et al.ARTICLEAIDS and Behavior2026
Methamphetamine use is prevalent among people with HIV (PWH) and complicates HIV care. Integrated substance use and HIV care services are recommended, yet rarely available. Contingency management (CM) is an evidence-based treatment for methamphetamine use, but its implementation within HIV primary care is limited. This study identified determinants and strategies to support CM implementation in HIV care. Key informants from an HIV clinic at an ac…

Background: The participation of Black individuals in clinical trials remains lower than that of other racial and ethnic groups. Substance abuse adds additional barriers to recruitment and retention. While significant attention has been devoted to identifying barriers to recruitment/retention, efforts have been largely unsuccessful in increasing the participation of Black individuals in clinical trials. This article details Phase 1 efforts to dev…

Nativity and the risk of opioid use disorder among Hispanic/Latinx women in primary care in Los Angeles, CA
Open AccessTakada, Marissa J Seamans et al.ARTICLEJournal of Ethnicity in Substance…2024
Among low-income Hispanic/Latinx women presenting to primary care, one in twenty patients is at-risk for OUD. The odds of moderate-high risk of OUD were three times as high in US-born compared to foreign-born women, and higher among those with chronic medical conditions and those at risk of other substance use disorders. Gender-specific and culturally-tailored screening for OUD may inform overdose prevention interventions for US-born Hispanic/Lat…
So that’s why I found PrEP to be safest way to protect yourself”
Open AccessAmanda P Miller, Sarah Schoetz Dean et al.ARTICLEBMC Public Health2024
Intimate partner violence (IPV) occurs at alarmingly high rates towards pregnant women in South Africa. Experiences of emotional, physical, and sexual IPV in pregnancy can adversely impact the health and safety of mother and fetus. Furthermore, IPV is associated with increased risk of HIV, exacerbating the public health impact of violence among pregnant women in this HIV endemic setting.

Open AccessMoka Yoo‐jeong, Andrea M Weinstein et al.ARTICLEAIDS and Behavior2024
Partnership status among sexual minority men (SMM) is a potentially important yet underexplored predictor of cognitive functioning. Using data from the understanding patterns of healthy aging among men who have sex with men substudy of the Multicenter AIDS Cohort Study, we assessed the associations of partnership status and quality with cognitive performance in middle-aged and older SMM, adjusting for sociodemographic and clinical covariates.

Disrupting the Path from Depression to Loneliness
Open AccessMaria De Jesus, David Ware et al.ARTICLEAIDS and Behavior2024
Existing studies examining resilience among sexual minority men (SMM) have been limited by only analyzing 1 level of resilience. We therefore investigated the impact of multiple levels of resilience on the bidirectional relationship between loneliness and depression symptoms among older SMM. Loneliness, depression symptoms, and multilevel resilience scores were collected across 3 time points (October 2016 to March 2017 [T1]; October 2017 to March…

The experiences of participants in this clinical trial can be distilled into four meta-themes: agency, caring-trust, safety, and communication. Participants spontaneously linked these experiences with a capacity to remain enrolled in the study. By considering the experiences of trial participants in clinical trial design, researchers can improve the experiences of future trial participants and facilitate their choice to remain enrolled in clinica…

Drug Use, Family Support, and Depressive Symptoms Among Latinx Sexual Minority Men
Open AccessHomero E del Pino, Nina T Harawa et al.ARTICLEAIDS and Behavior2023
Family rejection has negative health consequences for Latinx sexual minority men (LSMM). However, LSMM often reconcile with their families, a phenomenon cross-sectional studies miss. We analyzed longitudinal data from the Healthy Young Men's Study in Los Angeles. We used individual fixed-effects Poisson regression to model changes over time in the associations among family support, drug use, and depressive symptoms. We found that (1) the initiati…

Methamphetamine abuse as a barrier to HIV medication adherence among gay and bisexual men
Cathy J Reback, Sherry Larkins et al.ARTICLEAIDS Care2003
Medication adherence among persons with HIV infection is important not only because of the effect of non-adherence on an individual's health but also because non-adherence can lead to medication-resistant viral strains. However, adherence to HIV medications is difficult due to complex dosing regimens and side effects. This paper is a qualitative analysis of HIV medication adherence among gay and bisexual methamphetamine-abusing men enrolled in an…

BACKGROUND: In 1998, highly active antiretroviral therapy (HAART) was widespread, but the diffusion of these life-saving treatments was not uniform. As half of all AIDS patients in the USA have Medicaid coverage, this study of a multistate Medicaid claims dataset was undertaken to assess disparities in the rates of HAART. METHODS: Data came from 1998 Medicaid claims files from five states with varying HIV prevalence. ICD-9 codes were used to iden…
