Assessing Habitual, Goal-Directed, and Pavlovian Influences in Alcohol Use Disorder
The first aim of this study is to establish the role of maladaptive reliance on habits for impaired control in addiction, employing a novel task - the Action-Sequence-Task (AST), which assesses interference between habitual and goal-directed control. The AST, along with the developed computational model, will be employed to test …
Cue Effects in Human Addiction: Pavlovian to Instrumental Transfer
Individuals with substance use disorders (SUD) have to cope with drug-related cues and contexts, which can affect instrumental drug seeking as shown with Pavlovian to instrumental transfer (PIT) paradigms in animals and humans. The investigators aimed to investigate the impact of acute and chronic stress on Pavlovian-to-instrumental transfer (PIT), how …
Emergency Medicine Peer Outreach Worker Engagement for Recovery
This is an observational, prospective case-control study evaluating the effects of an emergency department community health worker-peer recovery specialist program (PCHW), the Substance Misuse Assistance Response Team (SMART). Aims of this study are to 1) understand participant experiences working with a SMART PCHW and identify possible mechanisms for successful recovery …
A Cross-Sectional Observational Study on Retained Drug Needle Fragments in People Who Use Intravenous Drugs
In addition to the well-known toxicological harms of intravenous drug (IVD) use, there can also be local tissue complications, including infections, venous sclerosis, tissue necrosis, and drug needle fragment retentions. Drug needle fragments in subcutaneous tissue may cause local symptoms (usually pain and infections), but they have also been identified …
Role of Pavlovian Mechanisms for Control Over Substance Use
During the first funding period (1st FP), the investigators developed a novel full Pavlovian-to-instrumental transfer (PIT) task that allows assessing both, general and specific PIT to investigate whether specific PIT differs between alcohol use disorder (AUD) and control subjects. Preliminary analyses of the full transfer task indicate that AUD participants …
Opioid/Benzodiazepine Polydrug Abuse
Benzodiazepine (BZD)/opioid polysubstance abuse (PSA) dramatically increases risks of overdose, disability and death; however, little is known about phenotypes that could be targeted to decrease this use and these associated risks. The opioid abuse epidemic is generating unprecedented numbers of overdoses (OD) and deaths from prescribed and illegal sources (e.g. …
MicroRNA Biomarkers for Neonatal Opioid Withdrawal Syndrome
Infants with neonatal abstinence syndrome (NAS) experience prolonged hospital stays and poor neurodevelopmental outcomes, in-part because of the lack of accurate, individualized, biologic assessments available to manage this increasingly common medical condition. The proposed study will define the molecular mechanisms that regulate the response to opioid withdrawal in the developing …
Longitudinal Study of Xenon-129 MRI Imaging Effects of Cannabis Smoking
This is a longitudinal study of the long-term health impact of cannabis smoking on the lungs. Participants will be followed over a period of 3 years, and impacts of cannabis smoking on the lungs will be measured with magnetic resonance imaging (MRI) using hyperpolarized xenon-129 gas, pulmonary function tests, exercise …
Chronic Cannabis Smoking, Oxidative Stress and the Pulmonary Innate Immune Response
This study plans to evaluate the effects of chronic cannabis smoking on lung health by evaluating its effects on pulmonary health, lung physiology and alveolar macrophage function.
Neurocognitive Abnormalities in Stimulant Abuse Among High-Risk Women
Substance use disorders and psychopathy are serious and costly mental health issues. Psychopathy is known to be associated with aberrant moral decision making and there is considerable interest in determining whether substance use disorders lead to impairments in these same cognitive processes. Recent large-scale research initiatives in forensic settings have …
