Active clinical trials for "Substance-Related Disorders"

The purpose of this study is to assess the risks of abuse, misuse and adverse events related to high dose buprenorphine. Approximately 1250 patients taking Subutex (Schering-Plough) or its Buprenorphine High Dose (BHD) generic (Arrow Laboratories) will participate in this study. Data will be collected using physician questionnaires and self evaluation patient questionnaires at the first visit and visits at 6 and 12 months.

The purpose of this treatment research study is to assess the effectiveness of buprenorphine maintenance treatment for opioid dependence delivered in a primary care clinic setting. This study will determine whether buprenorphine treatment in primary care is effective in reducing cravings, reducing illicit opioid use, reducing addiction severity, and retaining patients in primary care treatment for opioid dependence.

Background: The incidence of lung cancer is quite high among people with the human immunodeficiency (HIV) virus. Frequent smoking may explain that cancer increase, given that 50% to 70% of HIV-infected people are current smokers. Recent research suggests that other factors may be involved as well. Smoking habits, such as smoking earlier in life or smoking more cigarettes a day than others do, may have a role. Also, HIV-infected smokers seem to have a greater risk of chronic obstructive pulmonary disease (COPD). The association of HIV and COPD is important, because COPD itself is linked to an increased risk of lung cancer. About 1,600 subjects from the study known as ALIVE (AIDS Linked to the Intra-Venous Experience), which began in 1988 in Baltimore, Maryland, will be given a detailed questionnaire on smoking behaviors and lung cancer risk factors. They will also have spirometry testing, to evaluate lung function. Objectives: To better characterize smoking habits and compare tobacco use among HIV-infected and uninfected drug users. To compare serum cotinine levels and spirometry results, as a marker of tobacco use and a marker of damage to lung function, respectively. Eligibility: Patients 18 years of age and older who are in the ALIVE cohort. Design: Patients undergo the following procedures: Completing a questionnaire on smoking history. Questions include age when smoking began, periods of quitting smoking, average number of cigarettes per day for specific periods, amount of each cigarette smoked, depth of inhalation, type of cigarette, nicotine dependence, use of other smoked [Note: I would not mention that these drugs are illegal] drugs, exposure to environmental tobacco smoke, past medical history, and recent respiratory symptoms. Spirometry testing. Patients are asked to breathe as deeply as possible and then rapidly exhale into a tube. The forced expiration volume in 1 second reflects the average flow rate during the first second, and it can be used to determine the degree of pulmonary obstruction. Blood samples. Tests measure levels of cotinine, a chemical made by the body from nicotine. African American males, who constitute the majority of the ALIVE cohort, participate in this test. Results would show how much tobacco smoke has recently entered the body. For this test, researchers plan to evaluate 240 current tobacco smokers and 100 participants who report no recent cigarette use.

Background: - Recent research has suggested that prenatal exposure to drugs may affect specific brain processes, including working memory, stress response, and decision making. However, most of the research on the effects of prenatal drug exposure in humans has been conducted early in life, and very little is known about effects of prenatal drug exposure during the crucial brain development period that takes place during puberty and adolescence. The biological and psychological changes associated with puberty may increase adolescents' sensitivity to prenatal substance exposure. Researchers are interested in using functional magnetic resonance imaging (fMRI) scans to study brain function and learn more about the effects of prenatal drug exposure on adolescents. Objectives: - To examine the effects of prenatal substance exposure on working memory, decision making, and normal brain activity in adolescents. Eligibility: - Adolescents between 12 and 17 years of age who are enrolled in a larger follow-up study of children exposed to drugs in utero. Design: The study will involve a single outpatient session with two fMRI scans that will test working memory and decision-making processes. Participants will have brief medical history, a physical examination, and a urine test for drugs of abuse. Participants will then be trained on the working memory and decision-making tasks before having an initial MRI scan to provide a baseline reading. The fMRI scans will take 40 to 45 minutes each, and participants will have break in between as needed.

The proposed study will provide critical information on Ecological Momentary Assessment (EMA) design characteristics that promote retention in a vulnerable and under-represented population in research-youth experiencing homelessness. The study will use an EMA app to collect substance use, mood, craving, social surroundings, and trauma measures over a 14-day period in youth age 18-24 (n=40) recruited from Star House, a homeless youth drop-in center. Youth will be randomized in 2x2 factorial design (fixed incentive model vs. prize-based model; random assessment 3x vs. 6x per day).

This is a mixed methods longitudinal observational study to assess patient and provider perspectives on pain and pain management among pregnant women with opiate use disorder (OUD). The findings from this study will inform patient-centered approaches to pain management. Themes surrounding mothers' pain/recovery experiences that correlate with quantified pain and analgesia endpoints will be identified. Findings will also shape an appropriate patient-centered research agenda for obstetric pain management in patients with OUD.

Since its recent marketizing in France, the cannabidiol (CBD), a major component of cannabis, is used in many over-the-counter products in France. Some painful patients or patients suffering from addiction seem to use the CBD in search of therapeutic effects. Yet, there are no data available for patients in algology and addictology, particularly with regard to the prevalence of the use of CBD, the effects sought and felt. Faced with the emergence of the use of a substance with a therapeutic purpose but outside a medical framework and without monitoring of adverse effects, it becomes essential to characterize the use of CBD. The main objective of the study is therefore to assess the prevalence of CBD users in algology and addictology departments. Secondary objectives are to characterize the use of CBD as well as the users of CBD, and to evaluate the impact of the use of CBD on other psychoactive substances use or current drug treatments and the drug liking of CBD.

Medical students are heavy users of psychoactive substances, and even if levels of use vary depending on the universities, the average levels are higher than most other students. In France, however, the use of licit or illicit substance has not been precisely described in medical students. The aim of this study was therefore to define the different modes of consumption of medical students. Methods: This study was a cross-sectional survey in medical students from the University of Montpellier, and the investigators performed a cluster analysis of data. Both medical students and residents were included. Socio-demographic, medico-psychological and addictological data were collected.

Sport is a privileged area to promote socialization and health values, such as companionship; a healthy lifestyle; cooperation to achieve common goals, and justice, rejecting unjustified advantages in competition. The concept of fair play is on which the development of those values pivots. From a holistic perspective, it is possible to define fair play, not only as a way to participate but also as a way of projecting people in life with values, assuming a set of behaviors that enhance a healthy and respectful sporting experience with opponents, the companions, the spectators, the referees and all the agents that take part in the sport practice.

Mental health problems affect 10-20% of children and adolescents worldwide, with half of affected youth experiencing problems by the age of 14. Despite the early onset of mental health problems, evidence-based prevention and early intervention programs remain scarce. If left untreated, early-onset mental health problems can progress to become severe or chronic conditions, and incur significant medical and societal costs. The current project proposes an integrated screening and intervention model that was developed involving active youth, family and community engagement. This project, known as Inter-Venture, focuses on reducing barriers to youth mental health care and promoting early screening and intervention by fostering collaboration between school and community-based services providers. The Inter-Venture project is being conducted in the Montreal area (Canada), and consists of three intervention modalities. Namely, 1) systematic school-based screening and personality-targeted interventions for students most at risk of mental health problems and substance misuse (the Preventure program); 2) a parent program designed to strengthen parenting skills and to improve the management of child behavior problems (Cope/EQUIPE program); 3) integrated services provided by a multidisciplinary team of professionals (referred to as Inter-Action) for youth with significant symptoms of mental health problems, substance misuse and/or psychosocial difficulties. The intervention model involves knowledge transfer to boost capacity-building and improve the provision and sustainability of evidence-based interventions in community settings. The primary goal of the Inter-Venture trial is to assess the potential effect of the school-based targeted interventions and collaborative care in the prevention, early detection and reduction of mental health problems, substance misuse and psychosocial difficulties among young people. The secondary goal is to assess the effect of interventions on school performance and whether the interventions can protect cognitive functions that may be negatively affected by early-onset substance use and mental health problems, and promote cognitive development through the prevention of these difficulties.
