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.
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.
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.
