Background: Cocaine use disorders (CUD) is a complex brain disorder, involving several brain areas and neurocircuits. Effective treatments for CUD are still needed. Repetitive transcranial magnetic stimulation (rTMS) stimulates non-invasively parts of the brain. Preliminary data suggest that rTMS may help reducing cocaine craving and consumption. Researchers want to learn how the brain and the drug-seeking behavior may change with this treatment. Objectives: To test if rTMS can reduce cocaine craving and use, and also affect several mood, behavioral and cognitive alterations associated with prolonged cocaine use. Eligibility: Healthy, right-handed adults ages 18-65 who do have cocaine use disorder (moderate to severe). Design: This is a randomized, double-blind, sham-controlled study. The study includes three phases: 1) a rTMS continued treatment phase; a rTMS follow-up; and a no rTMS follow-up. Prior to participating, participants will be screened with: - Questionnaires - Medical history - Physical exam - Urine tests - MRI (structural) After being enrolled, baseline behavioral and imaging data will be collected. In particular, participants will undergo: - Questionnaires - Functional MRI During the continued rTMS phase, participants with cocaine use disorder will be randomized to receive real or fake rTMS. Repetitive TMS will be delivered during 10 outpatient treatment days, over 2 weeks (5 days/week). Following this phase, subjects will have 12 follow-up visits (once/weekly), during which they will receive rTMS, and behavioral and imaging assessments will be performed. At the end of the rTMS follow up period, participants will further receive 3 follow up visits (once a month), during which rTMS will not be performed, but behavioral data will be collected. Treatment includes: - rTMS: A coil is placed on the head. A brief electrical current passes through the coil. At each visit, participants will receive two rTMS sessions, with a 1hr interval between sessions. At the beginning of each rTMS session, they view cocaine-related images for few minutes. - MRIs at baseline and at follow-up visit #12: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner. - Repeat of screening tests and questionnaires - Urine toxicological screen
At discharge from outpatient treatment, researchers will recruit 300 young adults and randomly assign them to recovery support as usual control condition or the Smartphone Addiction Recovery Coach for Young Adults (SARC-YA) experimental condition. Participants in the experimental conditions will receive a smartphone, a calling/texting/data plan, and the SARC-YA mobile applications for the first 6 months post treatment discharge. Experimental participants will 1) complete a 2-3 minute recovery-focused ecological momentary assessment (EMA) at 5 random times a day, receive feedback on their current answers, and provided access to behavioral charting of their past answers over time; and 2) receive continuous access to a suite of self-initiated ecological momentary interventions (EMI) to support their recovery via tool box of coping tools, apps related to getting support, and apps related to maintaining a healthy lifestyle. Data include standardized assessments, urine tests, mobile phone metadata, EMA responses, and EMI utilization. The study's primary aim and hypothesis are: Aim 1: Test the effects of experimental assignment on the frequency of substance use. H1 Relative to the control group, participants in the experimental group will have lower scores on the quarterly Substance Frequency Scale (3, 6, 9 months post- discharge).
The main purpose of this project is to test whether Peer-Enhanced Motivational Interviewing (PMI) results in superior alcohol and marijuana use outcomes for emerging adults (EAs, ages 18-29) and their peers. Ninety peer dyads (total n = 180, ntarget client = 90, npeer = 90) are randomized to receive either Peer-Enhanced Motivational Interviewing (PMI) or Waitlist Control (WC).
- Addiction to drugs and alcohol is increasingly becoming a worldwide trend that is prevalent in both rich and poor countries . Substance abuse shows a significant warming to the health, social and economic build of families, communities and nations. Extent of worldwide psychoactive substance use is estimated at 2 billion alcohol users and 185 million drug users . - Substance abuse (including alcohol and drugs) is an important risk factor for poor health globally due to their intoxicating effects or their toxic effects on organs and tissues that lead to the development of diseases, injuries and other health conditions - Drug abuse is associated with the increased risk of cardiovascular diseases. A study on the need for hospitalization in approximately 4800 drug users found that 223 of these were admitted to hospital due to cardiovascular diseases . - The majority of abused substances or their metabolites are excreted through the kidneys and renal complications of drug abuse are very common .The involvement of the kidney due to drug abuse is either attributed to their elimination through the kidney, or a direct nephrotoxic effect. The damage may be acute and reversible, or chronic and can leads to end stage renal failure . - Addiction is responsible for different types of liver diseases including fatty liver, hepatitis and liver failure. . Intravenous drug addiction by sharing of contaminated needle is very important risk factor for the development of liver diseases, particularly hepatitis B and hepatitis C. Globally, 90% of new hepatitis C infections are attributed to drug injection . In the long run, substance abuse has negative effects on sexual functions and leads to the onset of sexual disorders. . - Long term use of alcohol was reported to inhibit of hypothalamic-pituitary-adrenal axis and reduces the release of gonadotropins from the pituitary . Morphine administration suppresses LH release and reduces the levels of testosterone, which affects testicular function.
This Phase II SBIR project is designed to address the critical public health problem of bullying and cyberbullying among middle school age youth. The project involves developing and testing bullying and cyberbullying prevention materials, including interactive classroom sessions and corresponding serious games, based on the evidence-based substance abuse prevention approach called Life Skills Training. The product has the potential to fill a gap in the intervention tools currently available to schools that can be widely disseminated throughout the country using existing marketing and dissemination channels and decrease the adverse consequences of bullying and cyberbullying as well as substance abuse.
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 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).
In the department for substance use disorders at Uppsala University Hospital there are two wards. One that is locked, where the patients that are emitted can not go out to smoke and another ward where there is a possibility to go out and smoke during the day. The smoking habits on those two floors will be compared and how they feel about smoking will be evaluated when they are admitted to the ward, at discharge, after 1 mont and after 6 months.
The purpose of this clinical study is to examine the established, therapeutic EMDR intervention for patients with substance use disorders (SUD). The EMDR method is an integrative and structured therapeutic method which assumes that memories which have been dysfunctionally stored can lead to harmful behavior. The EMDR protocol used for this clinical trials has been specifically developed for patients with SUD - the results should be compared with traditional therapy. For the assessment of the EMDR treatment some questionnaires are given at several times.
