Transcranial Direct Current Stimulation (tDCS) for Treatment of Substance Use Disorder

The researchers will test whether cognitively enhanced transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex can reduce craving in inpatients with cocaine use disorder or opioid use disorder. Neuroimaging before and after stimulation will establish the neural correlates of recovery and allow predictions of outcomes, which will be assessed throughout the study and one month after its completion. Results could pave the way towards development of a new self-administered intervention to reduce craving when it is needed the most, enhancing recovery real-time and in the natural environment in people with cocaine addiction as generalizable to other drugs of abuse and other disorders of self-control.

Metabolome and Gut Microbiome Changes During Smoking Cessation in Long-term Drug Therapy in a Therapeutic Community

Theoretical Framework: Cigarette smoking is the leading preventable cause of death worldwide, with nicotine dependence notably common among individuals with Substance Use Disorders (SUD). Smoking exacerbates both physical and mental health issues, further complicating the treatment of SUD. Current therapeutic approaches for SUD often prove inadequate, indicating a need for new strategies. Recent advancements in metabolomics and gut microbiome research have provided valuable insights into the biological mechanisms underlying addiction. Objectives: This study aims to investigate the therapeutic potential of smoking cessation for individuals with SUD, using a six-week intervention within a therapeutic community. The research specifically explores the psychobehavioral, metabolic, and gut microbiome domains. It is hypothesized that smoking cessation will improve emotional regulation, self-efficacy, and reduce substance craving, mediated by changes in metabolic and microbiome profiles linked to brain reward systems. Methods: A randomized controlled trial (N=150) will be conducted, examining outcomes such as clinical relapse rates, microbial and metabolic markers, particularly in choline and folate metabolism. Participants with SUD (n=100) will undergo a six-week smoking cessation intervention, with pre- and post-assessments, compared to a control group receiving treatment as usual. Metabolomic and microbiome analyses will be conducted using blood and stool samples, alongside psychological assessments via questionnaires. Assessments on a behavioural level will take place at a 3-months follow-up. A cross-sectional, non-interventional healthy control group (n=50) will be examined at a single timepoint with an anologous panel of psychological variables, blood and stool to ascertain differences between smokers with SUD and healthy controls.

Project SHIELD 2.0: Police Education to Support Public Health in Kentucky

The project is a pragmatic, quasi-experimental hybrid type II effectiveness-implementation trial of a structural HIV prevention intervention to address police behavior (arrests and referrals) and ultimately improve health among people who use drugs. The study involves a novel implementation strategy that engages behavioral health workers as "local champions" in the delivery of an evidence-based police education program (SHIELD training intervention). In addition to examining implementation outcomes, primary outcomes focus on assessing effectiveness of the intervention among police (specifically in reducing drug-related arrests and promoting referrals to Medications for Opioid Use Disorder (MOUD) treatment. The investigator's overarching effectiveness hypothesis is that after law enforcement organizations receive the SHIELD training intervention, the organizations will be more likely to refer people who use drugs to MOUD treatment and other health and social services, rather than arresting for low level possession offenses. The study will be conducted across different counties in Appalachian Kentucky.

Substance Use in Pregnancy - Optimizing Retention in Treatment

Substance use during pregnancy is a leading cause of maternal morbidity and mortality in the United States, with 55-80% of postpartum patients disengaging from substance use disorder (SUD) treatment within one year of delivery. Structural and social determinants of health, including housing instability, transportation barriers, and limited childcare access, further exacerbate disparities in treatment retention. This pilot study, conducted in two specialized prenatal care clinics, evaluates the feasibility and acceptability of two integrated strategies to promote sustained engagement in recovery-oriented services during the perinatal and postpartum periods. Aim 1 implements a standardized social needs screening and referral protocol to connect patients with community-based supports. Aim 2 pilots a contingency management intervention to incentivize recovery-supportive behaviors. Findings will inform the design of a larger multi-site randomized controlled trial to evaluate the impact of these interventions on treatment retention, overdose prevention, and maternal-infant health outcomes.

Substance Use in Pregnancy - Optimizing Retention in Treatment by Maximizing Opportunities for Management

Overdose is a national top-three leading cause of pregnancy-associated death, and maternal substance use disorder (SUD) accounts for an estimated $1.5 billion in healthcare spending each year. Treatment with medication and behavioral therapy lowers morbidity and overdose risk. However, studies have shown 55% to 80% of patients stop treatment within one year postpartum. Additionally, as a result of systemic inequities, historically marginalized patients are at greatest risk of overdose or death. We are conducting a study at WashU Medicine and University of Maryland, Baltimore clinics that offer prenatal care, addiction treatment, and extended postpartum support for patients facing the challenges of a SUD. Study participants will complete a structured screening and management of their social needs, and then will be randomly assigned to continue their usual care or to participate in a contingency management program, which provides incentives to continue treatment.

The Many Roads to Trauma Recovery: A Clinical Trial Comparing Empirically Supported Treatments for Veterans With Co-Morbid Posttraumatic Stress and Substance Use Disorder Symptoms

Veterans with co-morbid posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) are at substantial risk of developing hypertension and cardiovascular diseases that often lead to premature death, with some evidence that they may die over 10 years earlier than their counterparts. As such, determining ways to improve their health outcomes is vital. Heart Rate Variability Biofeedback (HRVB) may be one way to restore autonomic balance and teach veterans with PTSD / SUDs how to respond differently to their symptoms. Multiple studies have found that HRVB not only improves autonomic nervous system (ANS) regulation / flexibility among veterans with PTSD, but also reduces PTSD symptoms. Additionally, there is evidence that HRVB reduces cravings and SUD symptoms. Currently it is proposed that the improvement in the PTSD and SUD symptoms are due to a combination of improving ANS regulation and veterans utilizing the HRVB techniques as coping strategies for their symptoms. Yet, none of these studies examined how HRVB versus other active interventions differentially effected symptoms and physiological outcomes. It may be useful to examine HRVB to other active interventions . The current project proposes to alleviate this gap by examining the effects of HRVB to one a active control condition (i.e., Present Centered Psychotherapy; PCT) among 50-residential veterans engaging in PTSD residential programming. Veterans will be recruited from residential programs at the Coatesville VAMC and screened for probable PTSD and an active (i.e., past year) SUD. If eligible, they will attend a brief visit that will include being randomized, engaging in a diagnostic interview, a battery of questionnaires related to PTSD / SUDs, attached to physiology equipment, and then complete 3 tasks (i.e., baseline task, emotion induction, and HRVB or Self-Compassion Break). Upon task completion, all veterans will be screened for risk and begin one of the conditions. Similar research procedures will be conducted after their final session. This study would provide evidence for the real-world effectiveness of HRVB compared to a control condition among one of the highest risk populations treated at the VA, which may provide invaluable insight into active mind-body treatments for veterans with PTSD / SUD.

Contingency Management for Veteran Smokers Undergoing Major Elective Surgery

The goal of this study is to design and test the first mobile contingency management (CM) smoking cessation intervention for military Veterans undergoing major elective surgery. Smoking is the leading risk factor for postoperative complications and is associated with longer hospital stays, reoperations, and 30-day mortality. Smoking rates among patients undergoing major elective surgery are high, 22.3-43.0%. It is imperative to identify efficacious, strategically timed smoking cessation interventions for surgery patients. CM incentivizes smoking cessation through positive reinforcement (rewards) when bioverified abstinence is achieved. To ensure feasibility, CM must be tailored to the clinical context. CM for smoking cessation has never been delivered before and after major surgery, nor has mobile CM bioverification been trialed perioperatively. The investigators will develop and test a tailored mobile smoking cessation CM protocol for Veterans undergoing major elective surgery.

Microcurrent Neurofeedback as an Adjunct to Standard Care for Substance Use Disorders

The goal of this clinical trial is to learn whether adding Microcurrent Neurofeedback (MCN) to standard residential treatment helps adults with substance use disorder more than standard treatment alone. It will also learn whether MCN is feasible to deliver in a residential treatment setting. The main questions it aims to answer are: Does adding MCN to Standard Care reduce substance cravings more than Standard Care alone? Does adding MCN to Standard Care reduce symptoms of depression, anxiety, and PTSD more than Standard Care alone? Is it feasible to deliver MCN sessions and collect study measurements within a residential treatment program? Researchers compared Standard Care plus MCN to Standard Care alone to see whether adding MCN improved outcomes beyond standard treatment. Participants: Were enrolled in residential substance use treatment for at least 4 weeks before joining the study Were randomly assigned to receive Standard Care plus MCN or Standard Care alone Those receiving MCN attended 12 sessions over 12 weeks, each lasting 30-45 minutes Completed questionnaires about cravings, depression, anxiety, and PTSD symptoms at the start of the study, at 6 weeks, and at 12 weeks

Reducing Parental Substance Use and Enhancing Family Resilience Among Rural Families Through Ohio START

The goal of this observational study is to learn about the roles played by parental activity spaces and social networks in reducing parental substance use and promoting child and family health outcomes in the context of Ohio START (Sobriety, Treatment, and Reducing Trauma) for families in rural areas. This study will investigate if substance use treatment service referrals and family peer mentoring services provided by Ohio START lead to positive changes in parental activity spaces and social networks, and if these positive changes lead to better child and family outcomes. The main questions it aims to answer are: * Does having behavioral health services (referred by Ohio START workers) close to where parents spend their time help with substance use recovery and child health? * Does peer mentor support through Ohio START help parents build stronger social connections and family resilience, and does this lead to better long-term family health? * Do these associations differ in rural areas compared to urban areas? Participants will: * Answer survey questions about their substance use, parenting, child health, and family well-being across three waves (Wave 1: when they enroll in the study, Wave 2: 6-month follow-up, and Wave 3: 12-month follow-up) * Share information about places they go regularly (such as work, stores, and healthcare visits) * Share information about people in their support network

Preventing Overdose and Promoting Recovery Through Court Navigation

This project is a hybrid type I clinical trial to assess the effectiveness and implementation determinants of a peer-led court navigation program for people who use drugs and are passing through county courthouses. Courthouses are a common point of contact for people with behavioral health needs, but outside of specialty court models, they remain underexplored as a setting for connecting people to substance use disorder treatment and related services. This study will test whether court navigation led by peer recovery specialists can increase receipt of substance use disorder treatment and reduce overdose and incarceration. Peer court navigators will meet with participants in courthouse settings, assess their needs, provide information and referrals, and offer follow-up support for up to 3 months. Peer recovery specialists, who have lived experience with substance use recovery, are increasingly being integrated into criminal legal and community-based settings; however, peer-led court navigation remains an innovative and understudied approach.

First Step Program for Substance Use Disorders

This study examines whether a newly developed four-session psychosocial treatment program, called the First Step Program, can be delivered in real-world hospital settings to people receiving inpatient care for substance use disorders in Korea, and whether it shows early signs of benefit. The program combines motivational interviewing, acceptance and commitment therapy, and group activities, and is delivered twice a week over about two weeks (four 50-minute sessions). About 20 adults will take part at two psychiatric hospitals. Participants complete brief questionnaires and a short interview about their motivation to change, craving, engagement in valued living, and social support before the program, immediately before and after each session, within one week after the program ends, and again at 1 month and 3 months after completion. After the program, some participants also join a small group discussion (focus group interview) to share their experience of the program. Because this is a small, single-group preliminary (pilot) study without a comparison group, its primary purpose is to assess feasibility, that is, whether the program and the assessment approach work well enough, and to obtain preliminary effect and variability estimates to inform the design of a future large-scale randomized controlled trial.
