Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv

MUSC Theses and Dissertations

Mu opioid receptor (MOR) agonists are recognized to disinhibit tonic dopamine (DA) in the ventral striatum (VS), contributing to opioid addiction and euphoria. However, MOR agonists can also inhibit non-drug reward-seeking, and disrupt conditioned responding to aversive stimuli, a phenomenon not readily explained by tonic DA disinhibition. We hypothesized that this effect could be due in part to disruption of phasic DA responses to conditioned stimuli (CS) which critically shape and maintain behaviors during naturalistic reward and aversive processing. Because MOR effects on CS-evoked phasic DA are largely unexamined, we conducted in vivo fiber photometric recordings in water-deprived male and …

Drd2 Rs6276 Polymorphism And Trait Impulsivity In Individuals With Mixed Behavioral And Substance Addictions, Gabriela Zdunek, Remigiusz Recław, Aleksandra Suchanecka, Krzysztof Chmielowiec, Dariusz Larysz, Patryk Ilków, Kinga Łosińska, Jolanta Chmielowiec, Łukasz Jaworski, Anna Grzywacz

Baltic Journal of Health and Physical Activity

Background/Objectives: Impulsivity is a key transdiagnostic trait linked to dysregulated reward processing in both behavioral and substance-related addictions, as recognized in DSM-5. Dopaminergic genes, including DRD2, may modulate individual differences in impulsivity, particularly under conditions of increased addiction vulnerability. This study examined whether the DRD2 Exon 8 rs6276 polymorphism predicts impulsivity levels in men with mixed addictive behaviors compared with healthy controls. Methods: A total of 328 males (128 with mixed behavioral and substance addictions and 200 controls) were assessed. Diagnoses were confirmed using the MINI interview, and impulsivity was measured with the Barratt Impulsiveness Scale (BIS-11). Genotyping of …

Enhancing Resilience And Reducing Burnout In Oncology Nurse Practitioners Through The “Three Good Things” Intervention, Ernestine A. Muanya

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Background: Burnout among oncology nurse practitioners (NPs) threatens clinician well-being, care quality, and workforce retention. The World Health Organization (2019) defines burnout as a workplace condition caused by chronic unmanaged stress. Nationally, over half of healthcare professionals report burnout symptoms, with high rates in oncology (Deriglazov et al., 2025). In Texas, nearly 48% of advanced practice providers report emotional exhaustion and job-related stress (Patel et al., 2024). Objective: This single-group pre–post quality improvement project evaluated an eight-week, app-based Three Good Things (3GT) intervention to reduce burnout and enhance resilience among 19 breast medical oncology nurse practitioners at a comprehensive …

Is The Vaping Epidemic Linked To Neurologic Changes And Mental Health Diagnoses Amongst Us Adolescents?, Tracy Lin, Victoria Shwe

Rowan-Virtua Research Day

Vaping has significantly increased among U.S. adolescents, driven by the rise of e-cigarettes and flavored pods. Nicotine exposure during brain development is linked to changes in the limbic-dopaminergic system, white matter integrity, and increased risk of emotional and behavioral dysregulation. Higher rates of depression, anxiety, and suicidality are reported among adolescent users, with greater symptom severity seen in those with high vaping dependence. Though studies show correlation rather than causation, findings suggest vaping may contribute to rising mental health diagnoses. Addressing vaping’s neurological and psychological impact is critical to guiding prevention efforts, regulatory policies, and support for at-risk youth.

Autoimmune Encephalitis Presenting As Pseudodementia (Case Report), Renita Ng, Christie Richardson

Rowan-Virtua Research Day

Patients with autoimmune encephalitis frequently present with psychiatric symptoms including psychosis, behavioral changes, and affective disorders. Because of this, misdiagnosis of a primary psychiatric disorder in a case of autoimmune encephalitis is not uncommon. We present a case of autoimmune encephalitis in a 72 year old who was initially thought to have psuedodementia or catatonia due to variable collateral who later on LP was found to have markers and responded to steroid treatment. This case highlights the importance of maintaining a broad differential with patients who present with psychiatric alterations and to consider other causes of behavioral change.

How Does Exposure To Early-Life Stressors Shape Eating Behaviors In Adulthood?, Surabhi Panda

Rowan-Virtua Research Day

The objective of this literature review is to explore the relationship between early-life stress and the development of disordered or dysregulated eating in adulthood. A search was conducted across PubMed, CINAHL, Embase, and PsycINFO databases. Results from each study were compared and synthesized. Twelve studies were analyzed including case reports, systematic reviews, cohort studies, and cross-sectional studies. Research indicates that childhood emotional abuse, often more prevalent than other forms of maltreatment, is a significant risk factor for eating pathology, with studies investigating psychological mediators such as anger, anxiety, and dissociation in this relationship.

Understanding Obesity Risk In Intellectual And Developmental Disabilities: Key Diagnoses And Factors, Elizabeth Kolaski, Wendy Aita, Jennifer Lecomte, Andrea Iannuzzelli

Rowan-Virtua Research Day

Background:

Individuals with intellectual and developmental disabilities (IDD) have obesity rates nearly twice those of the general population, leading to higher rates of diabetes, hypertension, sleep apnea, and reduced quality of life.¹ Genetic syndromes such as Prader-Willi syndrome (PWS) and conditions like autism spectrum disorder (ASD) and Down syndrome (DS) feature distinct mechanisms driving weight gain.² The burden of obesity in IDD exacerbates health disparities and strains caregivers and healthcare systems.³ Yet, comparative obesity prevalence and its drivers across specific IDD diagnoses remain poorly characterized.⁴

Hypothesis:

Obesity prevalence and underlying risk factors differ among IDD diagnoses …

Effects Of Social Isolation On Cecum Opioid Receptor Expression And Affective Behavior, Jordan Riser, John Tkaczynski, Nicole Shellenbarger, Maya Patel, Daniel Chandler, Daniel Manvich

Rowan-Virtua Research Day

BACKGROUND

Psychological stress can induce gastrointestinal symptoms and exacerbate existing gastrointestinal disorders, indicating an interaction between the central and enteric nervous systems. Central nervous system activation of opioid receptors stimulates sympathetic outflow to the enteric nervous system, delaying motility and reducing gastrointestinal secretions, producing a similar clinical presentation to IBS.

HYPOTHESIS

We hypothesize that social isolation induces anxiety states, disrupting homeostatic noradrenergic activity in the brain and gut, leading to neurophysiological changes in the cecum characterized by altered expression of opioid receptors.

METHODS

Sprague-Dawley rats were housed in either group (control) or socially isolated conditions. Affective behavior was assessed using …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

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 …

Effects Of Social Isolation On Locus Coeruleus Opioid Receptor Expression And Affective Behavior, John Tkaczynski, Jordan Riser, Maya Patel, Nicole Shellenbarger, Jin Park, Daniel Manvich, Daniel J Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Social isolation is a stressor that impairs homeostatic neuroendocrine functions and is associated with the development of several mood disorders characterized by persistent negative affect. Persistent feelings of loneliness have been growing public health concerns for several years and were greatly exacerbated by the onset of the COVID-19 pandemic. The problem has grown so severe the U.S. Surgeon General recently declared loneliness to be an epidemic health concern that is associated with poor mental and somatic health outcomes. Therefore, identifying mechanisms of neuroadaptation that contribute to the development of persistent negative affect is a critical step in the identifying better …

Impact Of A Suicide Prevention Learning Module For Firearm Training Courses In Louisiana, Claire Houtsma, Lauren Reyes, Katherine Macwilliams, Gala True

School of Medicine Faculty Publications

Background: Firearm suicide is a leading cause of death in the United States. Suicide prevention experts have advocated for upstream interventions that can be implemented prior to the development of suicidal thoughts, particularly those that focus on lethal means safety (LMS; e.g., increasing secure firearm storage). To reach firearm owners with LMS messaging, researchers have developed suicide prevention training content which can be incorporated into firearm training courses. However, no study to date has evaluated impact of such training on firearm course students’ subsequent knowledge, attitudes, and openness related to secure firearm storage. Thus, the current study sought to examine …

Perturbations In Risk/Reward Decision Making And Frontal Cortical Catecholamine Regulation Induced By Mild Traumatic Brain Injury, Christopher P Knapp, Eleni Papadopoulos, Jessica A Loweth, Ramesh Raghupathi, Stan B Floresco, Barry D Waterhouse, Rachel L Navarra

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Mild traumatic brain injury (mTBI) disrupts cognitive processes that influence risk taking behavior. Little is known regarding the effects of repetitive mild injury (rmTBI) or whether these outcomes are sex specific. Risk/reward decision making is mediated by the prefrontal cortex (PFC), which is densely innervated by catecholaminergic fibers. Aberrant PFC catecholamine activity has been documented following TBI and may underlie TBI-induced risky behavior. The present study characterized the effects of rmTBI on risk/reward decision making behavior and catecholamine transmitter regulatory proteins within the PFC. Rats were exposed to sham, single (smTBI), or three closed-head controlled cortical impact (CH-CCI) injuries and …

Review Of Psychogenic Nonepileptic Seizures And Patient-Centered Approaches To Care, Rabeel Ahmad, Rebekah Dietrich, Munaza Khan

Rowan-Virtua Research Day

Psychogenic nonepileptic seizures (PNES) are defined as involuntary experiential and behavioral responses to internal or external stimuli. They are behaviors, not associated with pathological alterations in the physiology of the brain. Although some of them mimic syncope, they have historically been regarded to clinically resemble epileptic episodes.

There is a multiplicity of different names for this condition. PNES is the most widely used term, though the term "functional seizures" is increasingly used. Alternatives such as "psychogenic seizures," "dissociative seizures," "psychogenic nonepileptic attacks" (PNEA), and "nonepileptic seizures" are also used.
