Filter by:The objective of this study is to better understand the comprehensive integration of both clinical and genetic factors that will help to identify mothers who could be at an increased risk of poor response to opioid substitution and infants at risk of significant neonatal abstinence syndrome (NAS).
The investigators hypothesize that opioid use in African-Americans will be associated with hypodopaminergic alleles that alter the threshold for activating feelings of reward and pleasure within the dopaminergic system, and that these allelic frequencies will differ significantly from European Americans. Planned is a targeted system to study genetic risks for reward deficiency using risk gene panel to assign a genetic addiction risk score (GARS), comprehensive surveys to determine quality of life and exposure to stressors and trauma. This system will allow prediction of addiction and relapse potential and delivery of personalized treatment.
The relapsing nature of opioid use disorder is a major obstacle to successful treatment. About 90% of those entering treatment will relapse within one year. To improve treatment outcome, new interventions targeting the underlying brain biomarkers of relapse vulnerability hold significant promise in reducing this critical public health problem. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that can modulate brain connectivity.
This is a multi-center prospective comparative cohort study examining the safety, efficacy, pharmacokinetics, and pharmacogenomics of naltrexone for pregnant women with opioid use disorder. Pregnancy, delivery, and maternal and infant outcomes to 12 months post-delivery will be examined and compared with a cohort treated with buprenorphine/naloxone.
The goal of this study is to evaluate whether using a novel drug-device combination to deliver buprenorphine/naloxone (B/N) to patients in office-based treatment for Opioid Use Disorder (OUD) is an effective way to improve compliance and treatment outcomes. The system introduces psychological and behavioral supports in addition to securing the medication between doses.
The aim of the study is to test the effectiveness of the Patient Decision Aid for Opioid Use Disorder (PtDA-MAT) by conducting a stepped-wedge cluster-randomized trial in CA H&SS (stratified by rural vs. non-rural areas) for adults with OUD. Patient outcomes will be tracked by (1) personal assessments (baseline, 3 months, and 6 months): drug use, overdose, healthcare utilization, and (2) clinical and administrative records (over approximately 24 months): drug treatment status and retention, physical and mental health diagnoses, arrest, incarceration, controlled substance use, and mortality. Multilevel models will be applied to test the intervention effects, controlling for possible temporal trends.
Despite the demonstrated effectiveness of agonist treatment for opioid dependence and alarming recent increases in overdose deaths, waiting lists for treatment persist. In a Behavioral & Integrative Treatment Development pilot study, the investigators demonstrated the initial efficacy a novel Interim Buprenorphine Treatment (IBT) to mitigate the risks (e.g., illicit opioid use, IV drug use) associated with treatment delays. However, consistent with that R34 mechanism, our initial pilot study involved a limited sample size and was conducted at a single academic, well-controlled research clinic with an extensive history of research. It is important to replicate these very positive pilot results and begin to evaluate whether they generalize to less-controlled rural environments that are being so adversely impacted by the current opioid abuse epidemic. In this Stage II randomized parallel two-group trial, the investigators will evaluate the efficacy of IBT using a larger sample of 100 waitlisted opioid-dependent adults (50 IBT, 50 WLC). UVM will serve as the coordinating center and we will aim to partner with health centers and other convenience sites in rural Vermont counties to conduct study visits while overcoming barriers commonly encountered in rural areas (e.g., transportation issues, socioeconomic barriers). The proposed research builds directly on the promising Stage I results and has the potential to substantially reduce the vast individual and societal costs associated with opioid treatment delays.
This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).
The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
