Hdac5 Enzymatic Activity Regulates Scn4b Expression To Control Relapse-Like Cocaine Seeking, Daniel J. Wood

MUSC Theses and Dissertations

Substance Use Disorder (SUD) is a relapsing disorder characterized by repeated seeking and use of psychoactive substances despite negative consequences to the individual. Epigenetic changes within the medium spiny neurons (MSNs) of the nucleus accumbens (NAc) are thought to underly the lasting propensity to relapse in SUD. The epigenetic enzyme histone deacetylase 5 (HDAC5) in NAc MSNs limits the formation of reward-cue associations in rodent models of drug seeking, but not sucrose seeking, leading to decreased relapse-like behavior. However, whether HDAC5 reduces drug seeking behavior through its own deacetylase activity or through the recruitment of co-repressors is unknown. Furthermore, these …

The Impact Of Legislation And Implementation Of An Emergency Department Medications For Opioid Use Disorder Program On Buprenorphine Administration, Jacob Manteuffel, Joseph Miller, Nadine Jawad, Alexis Maroney, Revelle Gappy, Nora Sharba, Grant Zydeck

Medical Student Research Symposium

The emergency department (ED) plays a critical role in addressing a wide range of healthcare needs and can be the first point of contact for individuals with opioid use disorder (OUD). Buprenorphine, a partial opioid agonist, is a medication that helps treat OUD. On January 12, 2023, federal changes removed a major barrier, allowing all clinicians to prescribe buprenorphine. Later in 2023, a Medications for Opioid Use Disorder (MOUD) program was implemented in a high-volume free-standing ED. We aimed to review the impact of these changes on buprenorphine administration.

We conducted a retrospective chart review of buprenorphine administration and ICD …

Delta-8 Tetrahydrocannabinol Policy And Related Health Impact Among College-Aged Individuals In South Carolina: A Scoping Review, Emily K. Luoma

Senior Theses

After the 2018 Farm Bill passed, loopholes were quickly found that led to the popularization of delta-8 THC, a derivative of delta-9 THC, more commonly known as marijuana. Use of this substance became particularly high in states that criminalized marijuana, such as South Carolina. This scoping review aimed to assess South Carolina’s current delta-8 policies in the context of health-related impacts among college-aged students. Comprehensively analyzing the results of relevant studies, it was determined that there are three commonly observed threats to public health that are direct outcomes of existing policies: 1) a lack of quality control standards; 2) misleading …

Unveiling The Stigma: Doctor Mental Health And Intervention Strategies, Joseph Heirigs

Honors Program: Senior Projects (Public)

Background

The mental health of physicians is a pressing issue that has received increasing attention in recent years. The alarmingly high suicide rates for physicians underscores the critical need to address the mental health challenges that doctors face. Physicians are exposed to stressors that are unique to their profession, including high-stakes decision making, long work hours, traumatic patient situations, and the emotional toll of patient care. These challenges contribute to high rates of anxiety, depression, burnout, and other mental health issues. However, despite these factors, physicians are often reluctant to seek mental health treatment due to fears of professional repercussions, …

Contraceptive Hormone Influences On The Role Of Primary Reinforcement And Reinforcer-Enhancement In Nicotine Self-Administration, Kathleen Robin Mcnealy

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Hormonal contraceptives contain a synthetic estrogen (e.g., ethinyl estradiol/EE) and/or a synthetic progestin (e.g., levonorgestrel/LEVO) and can exacerbate nicotine intake. However, whether altered intake reflects changes in nicotine reinforcement or enhancement by nicotine of co-occurring reinforcers is unknown. This reinforcer-enhancement effect is evidenced in rats when nicotine self-administration is increased by the presence of a visual stimulus (VS) reinforcer. This dissertation examined the effects of EE and LEVO on nicotine reinforcement and reinforcer-enhancement in ovary-intact female Sprague-Dawley rats. Rats were implanted with a jugular catheter and assigned to receive daily injections of EE (Vehicle, 0.125 [Low], or 0.18 [High] μg/day; …

In-Silico Modeling And Characterization Of Kcc2 Protein Interaction With A Small Molecule Direct Agonist Identifies Potential Binding Sites For Modulating Behaviors Associated With Substances Of Abuse, William Hai Dang Ho, Alfred Amendolara, Kenyon Mitchell, Jaden Miner, Ruth Northcott, Braxton Bingham, Andrew J. Payne

Annual Research Symposium

Purpose

KCC2 is a potassium-chloride cotransporter that plays a critical role in neuronal function by regulating GABAergic signaling via chloride gradients. Maintaining this concentration gradient is crucial for balancing excitation and inhibition in the brain. While KCC2 dysregulation has been implicated in epilepsy and seizures, recent studies suggest that KCC2 inhibition results in phenotypes mirroring those seen in chronic opioid dependence. As such, increasing evidence support KCC2 being a potential therapeutic target for modulating behaviors associated with substances of abuse. Currently, only a few direct small molecule agonists against KCC2 have been reported, and no definitive active site on the …

How Do Gender And Marital Status Impact High-Risk Polysubstance Use?, Kira England, Alexander Chapman

Population Health Research Brief Series

Drug overdose deaths in the United States increasingly include the use of multiple drugs, known as polysubstance use. These include opioids, cocaine, methamphetamine, tranquilizers, and sedatives. Polysubstance use is considered high risk because it can cause dangerous synergistic effects and result in the ingestion of higher amounts of drugs. This brief summarizes findings from a study that used data from the National Survey on Drug Use and Health on U.S. adults from 2002 through 2019 to examine gender and marital status differences in high-risk polysubstance use among U.S. adults ages 18 and older. The authors find that polysubstance use is …
