Objectives: Substance use disorders (SUDs) are a significant public health concern across the United States and may pose a risk to achieving sustained viral suppression (SVS) in people with HIV (PWH). This study aims to examine the association between SUDs and SVS among PWH.

Design: Using electronic health records from the South Carolina Department of Health, we conducted a retrospective study of adults diagnosed with HIV between January 2006 and December 2019.

Methods: The impact of SUDs on SVS was assessed using generalized linear mixed model. Potential confounders included age, sex, chronic diseases history, etc. Stepwise selection was performed to decide the confounders included in the final model, and the optimal correlation structure was determined by Akaike information criterion.

Results: Of the 9412 eligible participants, 7481 (79.48%) had reached SVS status during their follow-up periods. SUDs related to alcohol (adjusted odds ratio (AOR) = 1.70, 95% confidence interval (CI): 1.46-1.98), cannabis (AOR = 1.62, 95% CI: 1.35-1.95), cocaine (AOR = 1.95, 95% CI: 1.60-2.37), opioid (AOR = 1.91, 95% CI: 1.13-3.23), and tobacco (AOR = 1.80, 95% CI: 1.69-1.92) were negatively associated with SVS. Individuals with chronic conditions such as cardiovascular disease (AOR=0.31, 95% CI: 0.29-0.33), diabetes (AOR=0.49, 95% CI: 0.41-0.59), and cancer (AOR=0.47, 95% CI: 0.38-0.58) showed a higher likelihood of maintaining SVS.

Conclusion: This large cohort study of PWH with extended follow-up highlights the negative impact of SUDs on maintaining SVS. Long-term strategies for reducing substance use could support SVS in HIV patients.

Objectives: Racial and ethnic differences in long-term outcomes associated with medications for opioid use disorder (MOUD) are poorly understood.

Methods: The present analyses were based on 751 participants with opioid use disorder (OUD) who were initially recruited from opioid treatment programs located in California, Connecticut, Oregon, Pennsylvania, and Washington and participated in a randomized controlled trial and at least one follow-up interview. 9.

Background: Individual neurobiological heterogeneity among patients with tobacco use disorder (TUD) hampers the identification of neuroimaging phenotypes.

Methods: The current study recruited 122 TUD individuals and 57 healthy controls, and obtained their 3D-T1 images. Heterogeneity through discriminative analysis (HYDRA) was applied to uncover the potential subtype of TUD where regional gray matter volume (GMV) was treated as the feature.

Center for Tobacco Control Research and Education, University of California San Francisco, 95 Kirkham Street Box 1361, San Francisco, CA 94143, United States.

Unlabelled: Use of electronic cigarette (vaping) devices, whether to inhale nicotine, cannabis, or other substances, may pose health risks to adolescents. Those risks could be heightened when a vaping device is "fake," a term we use to include inauthentic, knockoff, counterfeit, and/or adulterated devices, an issue exemplified by the Electronic Cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI) outbreak of 2019-2020.

Methods: Investigators completed in-depth, semi-structured interviews in 2020-2021 with 47 California adolescents (ages 13-17) who used nicotine products.

Background: Human trafficking (HT) survivors are at risk for substance use disorder (SUD), although assessing the SUD epidemiology of HT survivors is difficult. This study used data from the 2019 to 2021 Nationwide Emergency Department Sample to estimate the prevalence of SUD for HT survivors utilizing emergency departments (ED) in the United States of America (US).

Methods: We included visits for patients aged 12-64 years with any International Classification of Diseases 10th Revision, Clinical Modification (ICD-10-CM) codes documenting HT as a cause of morbidity ( 1,688,  141) or history of HT ( 2,524,  218).

No FDA-approved medications for methamphetamine (MA) use disorder (MUD) are available. Suvorexant (SUVO), a dual orexin receptor antagonist that is FDA approved for insomnia treatment, reduces MA self-administration and MA-induced reinstatement responding in preclinical studies. SUVO may also reduce MA use by targeting substance use risk factors, including insomnia, stress, cue reactivity, and craving.
