Filter by: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 is a 4-phase study to implement the NIDA CDEs in primary care settings. Collecting and utilizing the CDEs in clinical practice requires a strategy for implementing screening to collect substance use information that populates the CDEs, and assisting primary care providers to offer appropriate interventions by providing clinical decision support (CDS) and a mechanism for making referrals to addiction treatment. We aim to maximize the efficient adoption of screening, CDS, and treatment referrals by integrating all of these activities into the electronic health record (EHR). The study will be conducted at three sites, representing three large health systems. Each phase will include deliverables essential to move to the next phase, and an independent Advisory Committee will review progress and make recommendations at each transition about how best to progress to each subsequent phase. Based on progress during earlier phases, the Advisory Committee may recommend expansion to additional clinics or health systems during the second part of Phase 4.
This is a randomized controlled Phase II clinical trial designed to evaluate the effects of N-acetylcysteine (NAC) in reducing Alcohol Use Disorder (AUD) severity and Post Traumatic Stress Disorder (PTSD) symptomatology among individuals with current AUD and PTSD.
The purpose of this research is to develop an objective assessment based on the virtual reality techniques which is used for evaluate addiction severity.
High relapse rates among substance dependent individuals are likely due to a combination of factors that involve limbic circuits in the brain involved in craving, including vulnerability to salient cues. Emerging data suggests that non-invasive, targeted brain stimulation may be able to modulate activity in these circuits and decrease craving. The primary goal of this pilot study is to determine the extent to which a single session of continuous theta burst stimulation to the medial prefrontal cortex can attenuate limbic circuitry involved in craving among cocaine users and alcohol users. This will be tested through a double-blind,sham-controlled brain stimulation and brain imaging study in a cohort of polysubstance abusers and alcohol users.
In this study, the investigators are looking at how people make decisions about reward-related items, both monetary and food related after taking either the dopamine agonist bromocriptine or the COMT inhibitor tolcapone, in healthy control subjects. Subjects will fill self-report questionnaires and undergo an MRI scan.
This study will develop a clinical decision support tool that assists primary care providers in carrying out substance use interventions, and then compare (in Phase 2) two clinical scenarios, screening only (SO) vs. SUSIT, (on dose of substance use brief intervention received) and changes in drug use at 3 and 6 months, among primary care patients. Investigators will develop the Clinical Decision Support (CDS) component and then test the full SUSIT approach, using mixed methods to assess its acceptability and adoption, and gathering preliminary data on its efficacy for reducing unhealthy drug use. CDS development is concurrent with the SO phase to avoid losing valuable time, but will be conducted at a secondary study site to avoid contaminating the SO condition.
Cocaine addiction is a chronic condition with severe cardiac, neurologic, psychiatric and social complications. Cocaine is the second most consumed illicit drug in France. Its prevalence has been multiplied by 3 between 2000 and 2008, and is still on the rise. Craving, the compulsive need to consume, is a key feature of cocaine addiction. It is also predictive of treatment efficacy. However, there is no validated treatment for severe cocaine dependence yet. Response to current psychological and medical treatment is poor, with 73% relapse after 3 months. Patients with severe cocaine addiction are thus in a therapeutic deadlock. To address these unmet medical needs, the investigators designed a pilot study (n=2) to evaluate the safety and the efficacy of the deep brain stimulation of the subthalamic nuclei (STN-DBS) in severe cocaine addiction with at least one cardiac, neurologic or psychiatric complication. Indeed, compulsivity is a critical component of craving, and severe treatment-resistant obsessive compulsive disorder (OCD) are already successfully treated using STN-DBS. Moreover, animal studies recently demonstrated a therapeutic effect of STN-DBS in rats addicted to cocaine. Together, these two lines of research suggest a therapeutic effect of STN-DBS in cocaine addiction mediated by an anti-obsessive mechanism on craving.
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.
