Filter by:Study rationale Opioid use disorder (OUD) is a chronic and severe condition, defined by problematic opioid use, which results from interactions among sociological factors, psychiatric symptoms and life experiences, altogether determining OUD severity. Recently, behavioral epigenetics has emerged as a possible strategy to help identify molecular mechanisms that may explain how these various interactions result in dysregulations affecting gene expression, brain function, and, ultimately, emotional regulation. Here the investigators propose a pilot study as a first step towards a larger multidisciplinary project whose goal will be to characterize simultaneously major psychiatric and social factors in individuals with OUD, across a wide range of disease severity. In the present pilot study, the investigators propose to first characterize technical feasibility of the molecular investigations proposed in these 2 projects. OUD severity The severity of OUD is well defined in the DSM-5 (2013), with 3 categories, from mild to severe, on the basis of the number of dimensional criteria met by patients (among 11 criteria). These criteria relate to the following main aspects: tolerance, the need to increase the amount of drugs to avoid withdrawal; psychic and physic withdrawal in case of substance discontinuation; social and interpersonal consequences of drug use; biological and psychic consequences of use; and craving, the irrepressible need to consume1. Here, the investigators postulate that molecular adaptations detected in the blood of OUD patients may represent biomarkers of this severity. Epigenetic blood biomarkers A main limitation for conducting peripheral blood biomarker investigations in active opioid abusers comes from the fact that phlebotomies are reputedly difficult & potentially iatrogenic in these subjects, as they associate with external cues and trigger internal states that are closely related to drug consumption. To overcome this difficulty, we propose to test the hypothesis that sufficient DNA amounts can be recovered from fingerstick blood drops (corresponding to capillary blood, similar to sugar testing) to generate robust and reliable DNA methylation measures in the full human epigenome. In other words, the investigators assume that DNA methylation can be measured using capillary blood. Objectives The investigators will first investigate in healthy volunteers whether the method consisting in collecting and analyzing small DNA amounts from capillary blood (fingerstick blood drops) retrieves DNA methylation measures for a number of CG dinucleotide sites (where DNA methylation occurs in the mammalian genome) that is comparable to that classically observed using veinous blood (phlebotomy). Second, the investigators will test the feasibility of measuring DNA methylation using capillary blood samples collected from patients with OUD. To this purpose, the investigators propose to collect veinous and capillary blood samples from healthy volunteers, and capillary blood from opioid users.
Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.
This study aims to investigate the benefit of administering two differing doses of Bupropion (BUP) to smokers to assist with smoking cessation.
Computer-based Training for Cognitive Behavioural Therapy (CBT4CBT) is a new on-line addiction treatment developed by Dr Kathleen Carroll at the Yale School of Medicine in New Haven, Connecticut. CBT4CBT consists of seven one-hour long online sessions that teach key concepts, including dealing with cravings, problem solving, and decision making skills, to help users reduce substance abuse. CBT4CBT has been rigorously tested throughout various communities in the United States with great success and is currently being rolled out throughout the States. The therapeutic approach of CBT4CBT is unique as its efficacy, durability and cost-savings have been proven in several rigorous clinical trials and will be magnified by the fact that the program can be delivered in Canada, allowing for increased and continual improvements in population health. CBT4CBT has been accepted by both patients and addiction treatment personnel alike and has won numerous clinical innovation awards. A collaboration has now been formed between Dr Carroll and Drs Michelle Patterson and Juergen Krause of the UPEI Centre for Health and Community Research (CHCR) that will bring CBT4CBT to Canada. While CBT4CBT has previously been tested in urban areas, there are many advantages to offering computer-based training to more rural populations (such as PEI). These more remote areas frequently suffer from a lack of services, as well as a lack of continuity with the services currently offered. CBT4CBT may very well provide that needed continuity to Addictions treatment and has also been shown to improve retention.
No medication existed for BQ dependence. No clinical trials existed for the drug therapy. Previous study showed that BQ possessed the antidepressant effect via pathway of monoamine oxidase A (MAO-A). An animal model also found that the arecoline from BQ has a property as MAO-A inhibitor. Therefore, the investigators hypothesized that inhibition of the MAO-A or antidepressants might reduce the BQ addiction severity. The investigators will conduct the randomization and double blinded with placebo controlled study with 90 participants with BQ dependence from the Family Medicine and ear, nose, and throat (ENT) outpatient department (OPD). All participants shall agree the informed consent. The range of age is from 18 to 65 years old. The participants are diagnosed as BQ use disorder without other psychiatry co-morbidity, according to the Diagnostic and Statistical Manual (DSM)-V criteria. Those who have severe physical illness, psychiatric illness, and other substance use disorder except cigarettes are excluded. All participants receive the semi-structure interview by DSM-V, International Classification of Diseases (ICD)-10, and Mini International Neuropsychiatric Interview by the psychiatrist. Before the intervention, the participants will finish their basic data, daily amount of cigarettes, betel nut, medical history and psycho-social rating scales. Next, in addition to counseling, the investigators will continue or modify the optimal antidepressants based on the previous results. The investigators will evaluate their BQ use condition as what has been measured in the natural observation study of the first year. The investigators will check the outcome measurement by visual analog scale, betel quid withdrawal severity scale, Yale-Brown Obsessive-Compulsive (Y-BOCS) - betel quid (BQ) scale. The investigators also followed their hamilton depression scale; Beck depression index; and Beck anxiety index in the baseline, 2nd, 4th, 6th , and 8th week. The investigators also obtained the participants' gene type if the participants also agree for the prediction of oral cancers.
A prior study by the principal investigator of this project identified dopamine- and oxytocin-related brain pathways that showed a diminished response when addicted mothers viewed the faces of their own vs. unknown infants, compared with non-addicted mothers. These areas include the hypothalamus, striatum and ventromedial prefrontal cortex. In addition, the investigators plan to examine activation patterns within the salience network, which includes the anterior cingulate cortex and the anterior insula. Oxytocin, a neuropeptide with decreased blood levels seen in addicted mothers, is integrally involved in maternal brain and behavioral responses. When administered intranasally, the pilot data has shown enhanced activation of the striatum, prefrontal cortex (PFC) and amygdala. The purpose of this study is to continue and expand upon the previous investigation of maternal addiction, by conducting a randomized, double-blinded, placebo controlled, crossover study of intranasal oxytocin on maternal brain responses. 150 mothers from the University of Iowa and the Yale Child Study Center will be enrolled (75 with a history of drug addiction and 75 matched control mothers), along with their 2 to 12-month-old infants, to participate in four study visits over a two-month period.
This study is to compare two groups undergoing opioid weaning as ordered by their referring physicians. One group will undergo the standard opioid weaning process and the other group will have the addition of the NADA Protocol to the weaning process.
Our hypothesis is that the conventional treatment of Behavioral Addiction in Parkinson's disease is often not effective, and that affects the motor aspects (worsening akinéto-rigid syndrome and / or worsening of dyskinesia due to higher levodopa doses to compensate for the drop in behavioral addictions) and non-motor (withdrawal syndrome dopamine agonist) anxiously including apathy. Our goal is to describe the natural history of Behavioral Addiction under the effect of the evolution of the disease and adapt treatment according to the prior art, through a study of a larger population of patients than in the few published studies.
The aim of this study is to determine whether a group format Community Reinforcement and Family Training (CRAFT) and Self-Directed CRAFT Delivery are more effective than non-intervention in terms of Concerned Significant Others (CSO) well- being and cost- effectiveness.
