Neural correlates of systemic lidocaine administration in healthy adults measured by functional MRI: a single arm open label study.

Introduction: Intravenous lidocaine is increasingly used as a nonopioid analgesic, but how it acts in the brain is incompletely understood. We conducted a functional MRI study of pain response, resting connectivity, and cognitive task performance in volunteers to elucidate the effects of lidocaine at the brain-systems level.

Methods: We enrolled 27 adults (age 22-55 yr) in this single-arm, open-label study.

Variation in Opioid Agonist Dosing in Clinical Trials by Race and Ethnicity.

Importance: Racial and ethnic disparities in access to treatment and quality of treatment for opioid use disorder (OUD) have been identified in usual care settings. In contrast, disparities in treatment quality within clinical trials are relatively unexamined.

Objective: To estimate racial and ethnic differences in the dose of opioid agonist treatment for OUD in the first 4 weeks of treatment in clinical trials.

Culturally adapted safer sex skills building: development and initial testing of an HIV prevention intervention for Black women using substances in the United States.

Black women who use substances in the United States face unique human immunodeficiency virus (HIV) risk factors. However, interventions addressing cultural factors relevant for preventing HIV risk behaviors among Black women are limited. This project aimed to develop and initially test the effectiveness of a culturally adapted version of safer sex skills building (SSSB), an evidence-based HIV prevention intervention for reducing HIV risk among Black women who use substances.

Integrative data analysis of clinical trials network studies to examine the impact of psychosocial treatments for black people who use cocaine: Study protocol.

Background: Cocaine overdose death rates among Black people are higher than that of any other racial/ethnic group, attributable to synthetic opioids in the cocaine supply. Understanding the most effective psychostimulant use treatment interventions for Black people is a high priority. While some interventions have proven effective for the general population, their comparative effectiveness among Black people remains unknown.
