Filter by:Background: The chemical messenger dopamine carries signals between brain cells. It may affect addiction. Heavy use of pain medicines called opioids may decrease the amount of dopamine available to the brain. Researchers want to study if decreased dopamine decreases self-control and increases impulsiveness. Objective: To learn more about how opiate use disorder affects dopamine in the brain. Eligibility: Adults 18-80 years old who are moderate or severe opiate users Healthy volunteers the same age Design: Participants will first be screened under another protocol. They will: - Have a physical exam - Answer questions about their medical, psychiatric, and alcohol and drug use history - Take an MRI screening questionnaire - Give blood and urine samples - Have their breath tested for alcohol Participants will have up to 3 study visits. They will have 2-3 positron emission tomography (PET) scans. A radioactive chemical will be injected for the scans. Participants will lie on a bed that slides in and out of the donut-shaped scanner. A cap or plastic mask may be placed on the head. Vital signs will be taken before and after the PET scans. Participants will get capsules of placebo or the study drug. They will rate how they feel before, during and after. Participants will have their breath and urine tested each day. Participants will have magnetic resonance imaging (MRI) scans. They will lie on a table that slides into a cylinder in a strong magnetic field. They may do tasks on a computer screen while inside the scanner. Participants will have tests of memory, attention, and thinking. Participants will wear an activity monitor for one week....
This study seeks primarily to test, in a two-arm randomized controlled trial (RCT), the efficacy of Project IMPACT, an intervention that integrates Behavioral Activation (BA) with HIV risk reduction (RR) counseling for HIV-uninfected men who have sex with men (MSM) with stimulant use disorder at risk for HIV via sexual behavior. HIV-uninfected MSM with a diagnosis of stimulant use disorder will be equally randomized to one of two study arms: (1) the Project IMPACT intervention, BA-RR counseling, which lasts ten sessions; and (2) the standard of care (SOC) comparison condition, including two equivalent sexual risk-reduction counseling sessions. Participants will be followed for one year post-randomization, with assessments at months four, eight, and 12.
This study proposes to recruit patients with Opioid Use Disorder (OUD) seeking treatment into our program of outpatient detoxification and naltrexone induction followed by a relapse-prevention treatment with Extended release-naltrexone (XR-NTX) . Eligible participants will be randomly assigned to adjunctive treatment with lorcaserin (N = 40), or placebo (N = 20) with weekly therapy.
The goal of this study is to evaluate the effectiveness and utility of the investigator's National Institute on Drug Abuse (NIDA) R21 developed "Preventing Addiction Related Suicide" (PARS) program by utilizing a novel stepped wedge design to evaluate PARS as a selected prevention program to increase help-seeking by clients in community addiction treatment.
The purpose of this pilot study is to assess whether the hospital-based, adaptive behavioral intervention strategy promotes treatment entry and reduces risk of additional substance-exposed pregnancies (SEPs), as well as HIV and Hepatitis C Virus (HCV) risks among substance-using NICU mothers. Additionally, to assess whether the intervention increases use of professional obstetrical/gynecological resources for contraception to reduce substance-exposed pregnancies (SEPs).
The aims of this pilot study are: (1) to assess the feasibility and acceptability of a mobile application to educate military members about the risks of prescription drug misuse; (2) to determine if there is evidence that the mobile application plus treatment as usual reduces the risk of prescription drug misuse and shows differences in related measures compared to treatment as usual among military medical clinic patients currently taking prescription medication; and (3) if evidence of reduced risk is found, to estimate effect sizes for a future effectiveness trial. The pilot study will use a randomized controlled design with two groups. The control group will be provided with treatment as usual (TAU), and the experimental group will be provided with the prescription drug-abuse educational smartphone application in addition to treatment as usual (app + TAU). Self-reported measures of risk of misuse and related attitudes and knowledge will be administered to all participants at baseline, 1 month, and 3 months. The mobile app is a brief intervention designed to help military members to assess their risk for medication misuse and provide individualized feedback on risk level with recommendations for reducing risk. The app also contains other features, including sections in which to store information on current medications and look up drug interactions and provides resources for help.
The project focuses on investigating problematic medication use, especially overuse of potentially addictive drugs among the elderly. The investigators aim firstly to develop and validate instruments for detecting and describing behavioral aspects and consequences of dependence on, and misuse of, prescription medication among elderly. In addition to evaluating diagnostic utility of screening instruments, the investigators aim to identify and report characteristics, risk factors and consequences of medication misuse and dependence among the elderly.
The purpose of this study is to assess the abuse potential of single doses of pitolisant relative to phentermine HCl and placebo, when administered to healthy, non-dependent, recreational stimulant users.
This is a five-year R01 effectiveness trial where tribal partners are committed to assessing the Family Listening/Circle Program's effectiveness and disseminating the approach and intervention within Indian Country as a best practice in reducing substance abuse health disparities.Three specific aims of the grant are 1) To rigorously test effectiveness of FLCP; with a comparative longitudinal design within and across the tribes, with 4th graders to prevent substance initiation/use and strengthen families; 2) Through CBPR, support TRTs to transform their research capacities into local prevention research infrastructures and partnering; 3)To assess additional program effects on other health/education programs and leadership within the tribes. In sum, this multi-tribal/academic partnership builds on accomplishments to test the effectiveness of an innovative intervention. This grant provides an unparalleled opportunity to reduce substance abuse in three tribal communities, strengthen tribal research capacities, and impact substance abuse prevention research designs nationally, by illustrating how CBPR processes can integrate evidence-based and cultural-centered practices to create effective programs that generate community ownership and sustainability.
This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).
