this research adopted multicentered, randomly and parallel control methods to observe the clinical effects of electro-acupuncture combined psychological intervention on internet addiction disorder, aim to provide a convenient, affordable and effective clinical protocol.
120 individuals with alcohol, cannabis or nicotine dependence as well as healthy controls will be administered a whole-brain imaging exam. The current research project constitutes a highly novel approach to understanding the pathophysiology of addiction through its combination of neuroimaging with state-of-the-art information concerning the real-time expression of risk factors.
This study is part of the french priorities of the 2007-2011 addiction plan. Priority #2 of the plan underlines the need to improve practices and access to opioid substitution treatment. Priority 3 stresses the importance of articulation and coordination between specialized structures and community medicine to optimize the quality of care and to ensure continuity in the followup of these patients. This study focuses on the followup of patients under substitution therapy from the moment they enter a specialized care center for addicts to the period they are monitored by a general practitioner outside the specialized care center. The assessment described in this study should allow to harmonize and keep a continuity in patient monitoring.
This study uses an artificial intelligence platform to automatically confirm medication ingestion. The Health Insurance Portability and Accountability Act (HIPAA)-compliant platform can be downloaded as an 'app' onto any smartphone to automate directly observed therapy (Automated DOT®). Real-time patient adherence data are encrypted and automatically sent to a centralized web-based dashboard for use by healthcare professionals or research staff. Unlike Facetime® or Skype®, the system relies on computer vision algorithms to confirm the process of medication administration; no human review is necessary. The purpose of this study is to evaluate the feasibility and acceptability, and measure the accuracy, of the AiCure platform ("platform") in patients being treated for opioid dependence with Zubsolv® over the course of 12 weeks. The following aims will be tested: 1) to assess the feasibility and acceptability to both participants and study staff in using AiCure to monitor medication adherence; 2) to evaluate the acceptability of using AiCure to optimize care pathways; and 3) to measure the reliability and validity of AiCure in detecting interruptions in treatment. To assess feasibility and acceptability of the platform, we will measure rates of physician satisfaction and user acceptance. Optimization of care pathways will be measured by assessing the sustainability of AiCure use over 12 weeks (retention rates) and measuring illicit opioid use (urine drug screens) compared to historical data. Reliability and validity of AiCure will be measured by comparing AiCure adherence against pharmacokinetic data. All participants will be requested to take each of their prescribed doses using the app. Participants will be able to download the app onto their own smartphone or will be provisioned a device at the start of the study. The data captured during the medication ingestion process will be automatically encrypted and stored on the participant smartphone and uploaded wirelessly to a cloud-based dashboard. If a participant is non-adherent (missed dose, incorrect dosage) or if suspicious behavior is detected, an automated alert will be sent to study staff via email or SMS to prompt immediate intervention. In addition, all participants will receive treatment as usual.
Cigarette craving usually occurs with unpleasant feelings, including stress. Progressive Muscle Relaxation (PMR) may reduce level of cigarette craving and/or withdrawal symptoms.
Tobacco addiction is treatable with behavioral and pharmacological means, but results are often less than optimal. Transcranial direct current stimulation is a new non-invasive technique that applies weak electrical currents through the skull and has been shown to alter the excitability of certain brain areas. It is currently being tried in disorders where there is abnormal brain excitability, such as epilepsy and depression. A few studies have also been able to diminish drug craving, suggesting that brain excitability might also be altered in drug addiction. This study aims at non-invasively changing the excitability of certain brain areas-a procedure called neuromodulation- in order to help smokers quit smoking more easily.
Background: Substance abusers show impaired working memory (WM) functioning. Promising findings show training WM results in an improved working memory capacity (WMC) and a decrease of clinical symptoms in a range of disorders, including alcohol addiction. Aim: To test the effect of a WM training in addition to treatment as usual (TAU) on substance use, craving, WMC, impulsivity, attention bias and psychopathology. Design: A randomized double-blind placebo-controlled trial with a parallel group design. The WM training adapted to participants' WMC whereas the placebo training consisted of non-adaptive easy versions of these tasks. Setting: Two departments of an addiction treatment clinic in Rotterdam, the Netherlands. Participants: 120 inpatients diagnosed with an alcohol, cannabis or cocaine dependency who were in treatment as usual . Measurements: Primary outcome measures: Substance use and craving. Secondary outcome measures: WMC, impulsivity, attention bias and psychopathology. Participants were assessed before and after 24 sessions of WM training as well as two months after the training.
Background: - Small differences in genes may alter responses to drugs. One gene that has different forms is the mu opioid receptor gene. People with one form of this gene are more sensitive to alcohol. People with a different form are sometimes more sensitive to pain. Morphine and other prescription pain pills produce pain relief by acting at the mu opioid receptor. Researchers want to see the effect of morphine on brain reward and subjective effects. Morphine is a strong but short-acting pain medication that is sometimes used for anesthesia during surgery. Objectives: - To compare the effect of morphine on brain measures of dopamine release using imaging. Eligibility: - Individuals between 21 and 55 years of age who have previously taken pain pills prescribed to treat pain from a medical or dental procedure. Design: - This study has a screening phase and a study phase. The screening phase involves one or two visits of 5 to 6 hours. The study phase consists of 4 study visits. Each study visit will take about 8 hours. - Participants will be screened with a medical and psychiatric history and physical exam. They will be asked about drinking and drug-taking history, and any family history of alcoholism or drug abuse. Blood, urine, and breath samples will be collected. - During the first study visit, an MRI scan may be performed, questionnaires completed, and a blood sample collected for genetic testing. - During study visit 2, participants will test their pain sensitivity by placing one hand in cold water. Pupil diameter will be measured after the sensitivity test. After a blood sample is taken, participants will receive the morphine or a salt solution. The sensitivity test and pupil diameter test will be repeated. Final blood samples will be collected. A brief physical exam will also be performed. - During study visits 3 and 4, participants will receive morphine or a salt solution during a PET scan. Questionnaires to assess subjective effects will be administered. Final blood samples will be collected. A brief physical exam will also be performed. - Participants will stay in the clinic until the effects of the drug have worn off after study visits 2, 3, and 4. - About 1 week after the study session, participants will have a follow-up phone call.
The purpose of this study is to determine the feasibility and preliminary efficacy of attention training using a portable electronic device for opioid-dependent cocaine-users stabilized on methadone.
