Non-invasive Vagal Nerve Stimulation in Opioid Use Disorders UH3
Withdrawal SymptomsOpioid Use Disorder1 moreThis study is being done to answer the question: what is the effect of Vagal Nerve Stimulation (VNS) dosing on opioid withdrawal responses in individuals with a history of Opioid Use Disorders (OUDs)? Eligible participants will be in the study for one week in an inpatient research hospital stay, have an MRI scan, and have a follow-up call 1-3 months after their inpatient stay. Participants will complete several psychiatric questionnaires/interviews, physiological monitoring with several devices, brain imaging, and VNS testing.
Evaluating the Effectiveness of Mobile Self-guided Psychological Interventions to Reduce Relapse...
Substance Use DisordersAddiction3 moreThe aim of the study is to evaluate the effectiveness of mobile interventions in reducing craving and lapses in patients diagnosed with Substance Use Disorder. In a two-armed, randomized controlled trial the efficacy of self-guided psychological intervention delivered via a mobile app (Nałogometr 2.0) will be assessed. During the course of three months, participants will have access to intervention modules, based mainly on mindfulness and cognitive behavioral therapy (CBT). With the use of ecological momentary assessment (EMA), longitudinal data on several variables related to craving and lapse risk will be collected. Additionally, a questionnaire battery assessment - administered monthly - will measure severity of substance dependence, levels of anxiety, depression, and life satisfaction.
tDCS and Impulsivity
Substance Use DisordersSubstance Abuse1 moreSubstance use disorder (SUD) affects more than 23 million Americans and claims more than 70,000 lives annually. With 40-60% relapse rate, SUD patients are high hospital utilizers, 65% of the incarcerated population, and are at high-risk for overdose and deaths. There is a pressing need for research in this area to advance beyond traditional pharmacological and behavioral therapies toward a greater focus on the mechanisms of risk for relapse and to improve personalization for SUD treatment. Neuromodulation has shown promise to stimulate neuronal growth without any of the side effects of medications or electroconvulsive therapy. Using transcranial direct current stimulation (tDCS) to modulate cortical activity has shown to be a viable therapy in medicine-resistant depression, to reduce opioid cravings, and impulse control. The proposed research plans to recruit 30 subjects with a history of substance use disorder (SUD). This may include a history of addiction to opioids, cocaine, and barbiturates. Addiction to alcohol and cannabinoids (marijuana) will be excluded from this study. Following recruitment and consent, the subject will be administered an EEG, Acceptance Commitment Therapy exercise followed by EEG, and a BIS-11 Survey measuring levels of impulsivity. During the next week, the patient will undergo 5 visits consisting of a pre-EEG, tDCS, and post-EEG. Half of the subjects (n=15) will receive treatment, while the other half will be in a sham group. After the completion of the 5 tDCS visits, the patient will again be administered an EEG, ACT exercise followed by EEG, and a final BIS-11 survey measuring for end impulsivity levels.
Floatation-REST in Methamphetamine Use Disorder: A Pilot Study
Amphetamine-Type Substance Use DisorderThis early-stage trial aims to examine the feasibility, tolerability, and safety of Floatation-REST (Reduced Environmental Stimulation Therapy) or an active comparison condition in 50 individuals receiving treatment for Amphetamine-Type Substance Use Disorder.
AA on Drug Abusers by Nursing Students
Drug AbuseDrug abuse is a serious public health issue. Despite the serious consequences of drug abuse, there are around 2000 new cases reported by drug abusers each year. There is growing evidence of the use of auricular acupressure (AA), a traditional Chinese medicine (TCM) treatment modality, in reducing withdrawal symptoms among drug abusers. This study aims to investigate the feasibility and effectiveness of training nursing students to deliver brief education on AA on drug abusers.
Functional Connectivity Alterations in Suicidal Patients Among Opioid Users
Substance AbuseSuicide1 moreSuicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.
Neuroplasticity in Maternal Opioid Use Disorder (OUD)
Opioid Use DisorderOpioid use disorder (OUD) remains a major public health problem particularly for mothers in the perinatal period, for whom stress, relapse rates, and risk for overdose are elevated. The perinatal period is characterized by significant neural reorganization that determines outcomes for mothers and infants. OUD is also associated with neural reorganization, specifically neural circuitry implicated in stress regulation and reward processes. Interventions should therefore take advantage of this changing perinatal biology to enhance treatment response by targeting the aberrant neural circuitry compromised by maternal OUD. The investigators have developed and refined an evidence-based intervention for mothers with OUD designed to target these neural mechanisms and enhance the reward of caregiving; however, this has yet to be formally tested. Therefore, the investigators will examine maternal neuroplasticity using high-dense array electroencephalography (EEG) in mothers with OUD in response to our intervention. There will be 1 laboratory visit at pre-treatment, followed by 12 sessions of the evidence-based parenting intervention, and 1 laboratory visit at post-treatment. This study will attempt to validate the importance of taking advantage of the neuroplasticity in the perinatal period to optimize outcomes for mothers with OUD.
Adjunctive Bright Light Therapy for Opioid Use Disorder
Opioid Use DisorderSleep DisturbanceInvestigators propose to conduct a pilot single-blind, parallel arm, randomized placebo-controlled trial evaluating the feasibility, acceptability, and preliminary efficacy of bright light therapy on reward system functioning among patients undergoing medication-assisted treatment for opioid use disorder.

Cannabis UseAlcohol Use3 moreThe study will test a computerized treatment with subjects ages 13-17 years who are seeking treatment for alcohol and/or cannabis use. Youth will be recruited from the Center for Drug and Alcohol Programs (CDAP) Clinic in the Department of Psychiatry at MUSC. Follow-up assessments will be conducted at one- and three-months following treatment.
Suicidal Behavior in Patients Diagnosed With Bipolar Disorder
DepressionAlcoholism1 moreThe purpose of this study is to learn the environmental and psychological factors that impact suicidality in patients diagnosed with Bipolar Disorder. Additionally, the study aims to identify treatments to reduce the suicidal behavior and improve quality of life through a 6-week group-based intervention program.
