Filter by:At the age of 17, in Brittany, 94.9% of adolescents have experimented alcohol consumption 78.1% within a month and 25.5% report repeated episodes of Intensive Punctual Alcohol. Among the potential explanatory factors of this worrying epidemiology, social and cultural factors induce a social valuation of alcohol consumption and drunkenness. There are also individual vulnerability factors, particularly important in adolescence between experimentation and the transition to regular use or even to alcohol use disorders. Despite the extent of the damage, there is currently little reliable data on effective primary prevention strategies for dealing with addictive behavior. Many prevention programs target age range in school settings, to delay or reduce use of psychoactive substances. A meta-analysis on the impact of this prevention programs in school settings, concluded that most interventions are associated with no or little impact with respect to the goal of reducing psychoactive substances with teenagers. Among existing programs, "PREVENTURE" has been evaluated in 5 trials with high-risk teenagers identified in schools settings, in different countries (Canada, Europe). The results show a clear and robust effect on reducing alcohol consumption. This program has not been tested outside the school setting and a recent review mention the need to make this program more accessible by targeting vulnerable groups and studying the impact of this program on this population. The PREVADO study is a prospective, controlled, randomised, open-label study. After inclusion, the adolescent completes the questionnaire SURPS (Substance Use Risk Profile Scale). The SURPS is self-report questionnaire that assesses four well-validated personality risk factors for substance misuse (Impulsivity, Sensation Seeking, Anxiety Sensitivity, and Hopelessness). There is a 23-item to which adolescents are asked to respond using a 4-point Likert scale ranging from "strongly agree" to "strongly disagree" : Hopelessness (7 items), Anxiety Sensitivity (5 items), Impulsivity (5 items), and Sensation Seeking (6 items). Adolescents will be randomized into 2 groups (stratification on the 4 predominant risk personality types from the SURPS (Substance Use Risk Profile Scale) and on the recruitment modality) : - Intervention group : teenagers follow the "PREVENTURE" program and routine cares - Control group : teenagers follow routine cares
This project aims to develop a line of research using new non-invasive neurostimulation technology to treat adults with opioid use disorders (OUDs). In the short term, the investigators aim to identify novel target brain regions for neurostimulation treatment and characterize their effects behaviorally and neurally. In the longer term, investigators aim to use these preliminary data to justify NIH sponsored clinical trials to apply transcranial direct current stimulation and non-invasive deep brain stimulation to these areas to partially or completely disrupt addiction.
Since the 80's, the prevalence of obesity has more than doubled and despite progression of knowledge, interventions usually lead to a transient reduction in body weight that is not maintained in the long-term. These failures in weight management may be partly explained by an incomplete understanding of obesity risk and maintaining factors. Behavioral and neurobiological similarities between use of high palatable foods and addictive psychoactive drugs have led to the concept of food addiction. Addiction is defined as a loss of control of use, and its persistence despite accumulation of negative consequences. Craving, an uncontrollable and involuntary urge to use, has shown to be a core determinant of persistent use and relapse in addiction. Recent studies have established that food addiction, craving and emotional eating concern a large part of obese patients, and that food addiction may explain some negative outcomes of weight loss treatments, such as unsuccessful attempts to reduce calories and early termination of treatment programs. Recent advances in neuropsychiatry suggest that an imbalanced interplay between cognitive and affective processes impedes self-control and enhances over- or under-controlled behaviors. In the field of food intake and weight management, there is increasing evidence that besides environmental factors, inefficient executive functions and emotion regulation skills are salient phenomena underlying habit-forming processes that are present in eating disorder subtypes as well as obesity. This has led some authors to consider disordered eating behaviors as 'allostatic' reactions by which the modulation of food intake is used by vulnerable individuals to adjust to craving, maladaptive cognitive and/or emotional strategies. Current recommendations emphasize the need for translating these discoveries into treatments to promote healthy eating and weight management. Over the last 5 years, a growing base of clinical and behavioural studies have indicated that, individually, Cognitive-Behavioural Therapy (CBT), Emotional Skills Training (EST), and Cognitive Remediation Therapy (CRT) are promising techniques to decrease disordered eating behaviors, including craving. The investigators hypothesize that addition to treatment as usual (TAU) of a specific program targeting executive functions, emotional regulation, and addictive-like eating behaviors, could have a beneficial impact on reported food craving, and improve weight management among obese patients.
TCN PATHS will recruit an anticipated 400 participants who are prescribed MOUD who are released from detention facilities. Each individual will be randomized to either 1) standard primary care (SPC) or 2) a Transitions Clinic Network (TCN) program primary care. Participants will be followed for a year and complete surveys at baseline and at month 1, 3, 6, 9, and 12. At each of these points research staff will confirm MOUD status. Urine drug screenings will be completed at baseline, month 1, 6, and 12 if the participant is not incarcerated. When possible, research staff will collect electronic health records.
The current context of the Covid-19 health crisis leads to an over-solicitation of health systems, with hospital staff in the front line. These personnel are undergoing high levels of stress, an alteration of their life rhythm, but also of their health status and quality of life at work. In addition, night work, through the disruption of circadian rhythms, has consequences on physical and mental health. The more frequent worsening of the condition of certain patients at night increases the burden and responsibilities of night staff. Increasing the use of psychoactive substances (SPAs) can become a solution for managing stress, work rhythms, sleep disorders and their consequences. This self-medication behaviour is not without risks, neither for staff nor for patients. The ALADDIN study is a project made up of 2 waves of questionnaires - one during and the other after the Covid "hospital" crisis - filled in by the hospital night staff of AP-HP. This project will assess the impact of the Covid-19 epidemic on the quality of work life, mental health disorders, post-traumatic stress and substance use of hospital night staff. The main objectives of this study is to evaluate the prevalence of psychoactive substance consumption among the night shift healthcare workers of the AP-HP and to describe the participants' quality of working life. Methods The study is prospective study using an online self-completed questionnaire. The questionnaire was elaborated on the basis of the validated scales ASSIST (Alcohol, Smoking, and Substance Involvement Screening Test), AUDIT-C (Alcohol Use Disorder Test, shortened version) and HAD (for anxiety and depression) and on qualitative interviews conducted among care staff working the night shift. The questionnaire will be completed at t0 (baseline) and 18 months after. This study will provide data on the consumption psychoactive substances by night hospital workers adn their quality of working life. It will also allow us to compare their consumption with the general population, and to describe the risk factors influencing the consumption.
Food addiction (FA) is a behavioral addiction characterized by a high consumption of palatable foods, which markedly activate the reward system, despite adverse consequences. FA was first described in 1956 but remains controversial. The Yale Food Addiction Scale (YFAS), developed by Gearhardt et al. in 2009, is currently regarded as the "Gold Standard" for FA screening. In a previous study, we established a Food Addiction Screening Test using artificial intelligence. The main objective of the present study is to validate the sensitivity, specificity and precision for FA diagnosis in a sample of patient suffering from obesity and healthy volunteers.
Mindfulness-base interventions are promising interventions as an adjunctive therapy to be integrated into current existing anti-drug services. The advantages of MBRP can include: 1) having very low stigma as mindfulness courses are already widely accepted and used among different populations including healthy populations. The running of mindfulness courses can be more acceptable by the community; 2) it could be more accessible and cost-effective as it can be provided in group and in community settings; 3) it is a skill that can be learned and be used after the 8 week course , e.g. when the drug user is triggered in unforeseen circumstances, they may apply the learnt mindfulness skills to help themselves overcome the difficulties when timely professional help is not available; 4) Drug Abuse Statistics from Narcotics Division, Security Bureau of the government of Hong Kong showed that the most common reasons for recurrent drug use were to avoid discomfort of its absence (62%) and relief of depression/stress/boredom (30%). The study objectives are as follow: 1. To evaluate the feasibility of using mindfulness- based relapse prevention (MBRP) programme among adults with substance abuse in Hong Kong; 2. To examine the changes of craving, substance use, mood symptoms, self-efficacy, acceptance, level of mindfulness and quality of life between those who have enrolled in the MBRP as compared to those in the usual care control group; 3. To evaluate the correlations between changes in substance use and craving and changes in mood symptoms, self-efficacy, acceptance, level of mindfulness, and quality of life; and 4. To study participants' characteristics related to adherence and benefits associated with MBRP.
Improving knowledge about behavioural addictions is a real public health issue. The etiopathogenic model of behavioural addictions is multifactorial, with various risk and vulnerability factors, involved in the initiation and maintenance of the disorders. Among these factors, neurocognitive alterations associated with behavioural addictions has recently aroused interest among researchers. To our knowledge, there is no work wich compared several behavioural addictions with each other on a neurocognitive level. Moreover, neurocognitive data concerning certain behavioural addictions (such as sexual addiction) is almost non-existent. However, understanding the neurocognitive profiles of these patients would allow the investigators, on the one hand, to reinforce the existing literature and improve our understanding of the global process of addiction, and on the other hand, to propose alternative approaches to its management, taking into account the neurocognitive difficulties of the patients. The investigators therefore propose to explore the neurocognitive alterations of patients suffering from several behavioural addiction (sexual addiction, excessive use of video games and eating disorders with bulimia episodes), by comparing them with each other, to matched healthy control groups and to a recognized behavioural addiction (gambling disorder; data from the BANCO study - NCT03202290).
Methadone maintenance treatment (MMT) is one of the main forms of treatments for opioid dependence. Despite its effectiveness and widespread use, people will experience withdrawal if daily dose is insufficient or missed, promoting reluctance to attempt detoxification. In addition, methadone is a full opioid agonist which can induce respiratory depression or sedation without ceiling level, so overdose usage can be fatal. Hence, an alternative therapy is needed to completely reduce the carving for drugs and to relieve the negative affective sate caused by withdrawal. Deep brain stimulation (DBS) is a reasonable treatment approach for addiction. Since 2009 the first case report emerged, the nucleus accumbens (NAc) is still the only brain target to be investigated in clinical case series of DBS for alcohol and heroin addiction. This research will mainly investigate the effectiveness and safety of NAc-DBS for patients with methadone maintenance treatment. The investigators will also explore the influence of NAc-DBS on brain activity and cognition.
Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation in which low level electrical currents are applied to the scalp in order to alter brain function. In the present study, tDCS will be administered with the goal of assessing the tolerability and feasibility of this approach to 1) reduce an individual's level of drug craving and 2) provide evidence to support the use of this device by the patient for future unsupervised stimulation in a non-clinical setting. Research Questions: - Can tDCS be used successfully to train cocaine addicted individuals for self-administration purposes? - Can active tDCS be used to decrease drug craving in individuals with cocaine use disorders? - Does active tDCS outperform sham tDCS in reducing drug craving?
