Article Synopsis
  • The Communities That HEAL (CTH) intervention aimed to boost naloxone distribution in communities severely affected by opioid overdoses compared to standard care.
  • A study involving 67 communities in Kentucky, Massachusetts, New York, and Ohio revealed that naloxone distribution was significantly higher (79% more) in the CTH intervention group than in the usual care group over a year of monitoring.
  • The findings suggest that the CTH intervention effectively increased naloxone distribution, supporting its role in reducing opioid-related overdose deaths.

Article Synopsis
  • The study examines a community-based intervention aimed at reducing opioid-related overdose deaths by increasing the adoption of evidence-based practices including overdose education and naloxone distribution, medication treatment for opioid use disorder, and prescription safety.
  • In a cluster-randomized trial, 67 communities across Kentucky, Massachusetts, New York, and Ohio were assigned to either receive the intervention or serve as a control group during a period marked by the COVID-19 pandemic and an increase in fentanyl overdoses.
  • Results showed no significant difference in opioid-related overdose death rates between the intervention and control groups, with both averaging similar rates, indicating that the community-engaged strategies did not have a measurable impact during the study period.

Importance: Buprenorphine significantly reduces opioid-related overdose mortality. From 2002 to 2022, the Drug Addiction Treatment Act of 2000 (DATA 2000) required qualified practitioners to receive a waiver from the Drug Enforcement Agency to prescribe buprenorphine for treatment of opioid use disorder. During this period, waiver uptake among practitioners was modest; subsequent changes need to be examined.

Alcohol use is an important factor in achieving and maintaining viral suppression and optimal mental health among persons with HIV (PWH), however, the effect of age at first regular drinking on viral suppression and depression remains poorly understood. Here, using secondary data from the Alcohol Drinkers' Exposure to Preventive Therapy for Tuberculosis (ADEPT-T) study, we used logistic regression analyses to explore whether there is an association between age at first regular drinking and viral suppression (< 40 copies/ml), or presence of depressive symptoms (Center for Epidemiologic Studies Depression, CES-D ≥ 16) among 262 PWH. The median age at first regular drinking was 20.

Introduction: More than 70% of new HIV diagnoses in the United States were among men who have sex with men (MSM) in 2019. Pre-exposure prophylaxis (PrEP) is a transformative innovation for reducing human immunodeficiency virus (HIV) infections. Structural stigma against sexual minorities, including in the form of state-level policies, may affect PrEP implementation.

Objective: Isoniazid (INH) preventive therapy is recommended to prevent tuberculosis (TB) disease for persons with HIV (PWH), except for those with regular and heavy alcohol consumption, due to hepatotoxicity concerns. We aimed to quantify the incidence of severe INH-related toxicity among PWH with and without recent alcohol consumption.

Design: A prospective study of PWH receiving INH.

Alcohol use is especially problematic for people living with HIV (PLWH) and was likely to be impacted by the coronavirus disease (COVID-19) pandemic and its restrictions. In a study of PLWH with latent tuberculosis infection, we measured unhealthy alcohol use with the Alcohol Use Disorders Identification Test (AUDIT-C), phosphatidylethanol (PEth) and bar attendance. We analyzed data collected before and after COVID-19 restrictions, and used Generalized Estimating Equations (GEE) logistic regression models to evaluate changes in unhealthy alcohol use.

Background: The HEALing (Helping to End Addiction Long-term) Communities Study (HCS) is a multi-site parallel group cluster randomized wait-list comparison trial designed to evaluate the effect of the Communities That Heal (CTH) intervention compared to usual care on opioid overdose deaths. Covariate-constrained randomization (CCR) was applied to balance the community-level baseline covariates in the HCS. The purpose of this paper is to evaluate the performance of model-based tests and permutation tests in the HCS setting.
