RECRUITING

NCT07340554

Neuroimaging of Adolescent Cannabis Use Treatment

This study is testing whether brain activity related to learning can help predict how well teens respond to a treatment program designed to reduce cannabis use. Teens ages 14-17 will complete a brain scan and then take part in 10 weekly virtual sessions where they report cannabis use and complete drug tests at home. Participants can earn prizes for staying cannabis-free.

Harnessing Telemedicine to Improve Alcohol Use Disorder Outcomes in Primary Care Patients

The purpose of this trial is to test new programs to see if they might help people manage their health and health behaviors related to alcohol use and well-being. The program sessions focus on getting to know what's important to the participants, reviewing or setting goals, and using different skills and behaviors to better manage health. The trial will help the study team learn about ways to deliver health information in a way that is useful and interesting. This research will take place remotely (e.g., Zoom, Facetime, Phone) and participants will be randomized to the Telehealth (TeleTx) group intervention or the Enhanced Usual Care (EUC) control group. Both groups will be asked to have follow-up visits up to 12 months from the baseline visit.

Developing a Telehealth Model to Improve Treatment Access for Rural Veterans With Substance Use Disorders

This project will pilot-test and obtain stakeholder input on a telehealth-delivered substance use disorder (SUD) care model (with initial engagement and ongoing MI-CBT treatment) with the goal of increasing treatment utilization and improving outcomes for rural and non-rural Veterans with SUDs.

Examining Feasibility and Acceptability of Telemedicine for Substance Use Disorder (SUD)

The objective of this pilot intervention study is to iteratively refine motivational interviewing and psychosocial intervention programs delivered via telehealth (Teletx) to help improve substance use and other related outcomes in SUD patients who are not receiving SUD care. We will examine feasibility and acceptability of these pilot psychosocial programs in a total of n=50 participants. The goal is to refine the programs to improve acceptability and feasibility and collect preliminary data for a future fully powered randomized controlled trial (RCT) in the future. In addition to study sessions, participants that are enrolled in the study will complete surveys prior to, during, and after treatment.

Pre-exposure Prophylaxis (PrEP) for Health

This randomized controlled trial will test the efficacy of "PrEP for Health," a behavioral intervention to improve the use of antiretroviral pre-exposure prophylaxis (PrEP) among at-risk people who inject drugs (PWID) in two syringe service program (SSP) settings in Lawrence and Boston/Cambridge, Massachusetts. The investigators will equally randomize 200 PWID to receive either (a) the "PrEP for Health" intervention condition involving theory-informed HIV and PrEP education, motivational interviewing, problem-solving and planning, and ongoing patient navigation (n=100), or (b) the standard of care condition involving PrEP information and referrals (n=100). Successful PrEP uptake (via medical/pharmacy records), post-treatment PrEP adherence (assessed at 3 months via drug levels in hair), and longer-term PrEP adherence (assessed at 6 and 12 months via drug levels in hair) will be evaluated. The degree to which intervention efficacy occurs through specific conceptual mediators and differs according to hypothesized moderators will also be evaluated.

A Cross-Sectional Observational Study on Retained Drug Needle Fragments in People Who Use Intravenous Drugs

In addition to the well-known toxicological harms of intravenous drug (IVD) use, there can also be local tissue complications, including infections, venous sclerosis, tissue necrosis, and drug needle fragment retentions. Drug needle fragments in subcutaneous tissue may cause local symptoms (usually pain and infections), but they have also been identified as causing emboli to organs. The literature has described numerous case reports of people who inject drugs (PWIDs) and have retained needle fragments. The prevalence of the condition is not known, and the researchers therefore aim to perform the first cross-sectional study of PWIDs to estimate how common needle fragment retentions are and what their risk factors are in this population.
