The Clinical Trials Methodology Course (CTMC), given from 2014 to 2023, was conducted to educate early-career clinical investigators from various backgrounds in neurosciences in the design of clinical trials and to provide mentorship to enhance academic careers and retention plus improve research productivity and the likelihood of successful grant applications. This summary describes the rationale, history, structure, and trainee outcomes of the CTMC. The course used small groups, consisting of 1-2 clinical faculty advisor(s), 1 faculty biostatistician, and 2-4 trainees who met remotely approximately weekly over 12 weeks.

Background: People who inject drugs (PWID) are especially vulnerable to harms from opioid use disorder (OUD). Medications for OUD (MOUD) effectively reduce overdose and infectious disease transmission risks.

Objective: We investigate whether state Medicaid coverage for methadone and buprenorphine is related to past-year MOUD use among PWID using cross-sectional, multilevel analyses with individual-level data on PWID from the Centers for Disease Control and Prevention's 2018 National HIV Behavioral Surveillance.

Black women are disproportionately affected by HIV. We analyzed data from two Centers for Disease Control and Prevention's HIV surveillance systems to better understand HIV prevention strategies used by Black women at risk for and with HIV to help inform efforts to end HIV. Among sexually active Black women, we analyzed 2019 National HIV Behavioral Surveillance data on women without HIV (n = 4,033) and 2018-2020 Medical Monitoring Project data on women with HIV (n = 967).

Clinical trials of treatments for stroke have generally utilized 2-arm, randomized designs to evaluate a single intervention against a control. Running separate clinical trials, with each addressing a single therapeutic question, is resource intensive and slows evidence generation, especially in a field with rapidly expanding treatment options and evolving practices. Platform trials-randomized clinical trials designed to evaluate multiple interventions that may enter and exit the ongoing platform based on a master protocol-accelerate the investigation of multiple therapeutic options within a single infrastructure.
