Effects Of The Non-Stimulant Norepinephrine Reuptake Inhibitor, Atomoxetine, On Cognitive Flexibility In Healthy Adult Long-Evans Rats, Noah A. Ivak, Samantha Walkow, Christopher Knapp, Eleni Papadopoulos, Barry D Waterhouse, Rachel L Navarra

Rowan-Virtua Research Day

Executive function is the control of multiple higher order cognitive processes that include attention, working memory, and cognitive flexibility. Cognitive flexibility is the ability to shift behavioral strategies

in response to changing environmental demands and task complexity. This cognitive modality is often impaired in many neuropsychiatric disorders like attention deficit hyperactivity disorder (ADHD). Deficits in cognitive flexibility are associated with dysregulation of the catecholamines, norepinephrine (NE) and dopamine (DA) within the prefrontal cortex (PFC). Atomoxetine (ATX), a non-stimulant NE reuptake inhibitor, elevates levels of NE and DA in the PFC by inhibiting the norepinephrine transporter (NET). ATX is used to …

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. Adverse Childhood Experiences (ACEs) and early life …

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 …

Rowan-Virtua Research Day

Background: The onset of myopia in children has emerged as a significant public health concern, especially with increased screen time and reduced outdoor activity following the COVID-19 pandemic. The global prevalence of myopia is expected to rise significantly, with children being particularly vulnerable. Various studies have explored how screen time, near-work activities, and outdoor exposure influence the increasing prevalence of myopia in pediatric populations worldwide.

Hypothesis: This paper aims to evaluate whether increased screen time, especially following the COVID-19 pandemic, is associated with a higher prevalence of myopia in young children, providing a more robust understanding of this relationship across …

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 …

Cardiovascular Risk Factors In The Autism Spectrum Disorder Population, Christian C. Iannuzzelli, Andrea L. Iannuzzelli

Rowan-Virtua Research Day

The population of patients with Autism Spectrum Disorder (ASD) have multiple risks and barriers that may make access to proper health care more difficult. After extensive research, some of these barriers may have been identified that pose greater risks to generating proper care for those with ASD. Some of these barriers include medical complexity, more sedentary lifestyles, poor food choices, as well as health comorbities. Some of these health comorbidities include hypertension, metabolic dysfunction, sleep apnea, and inflammation. This study aims to understand what barriers and risks for CVD are present in those with ASD.

Exploring The Effects Of Target Race, Gender, And Weight On Pain Perception, Catherine Awad, Theresa Miller, Azer Tuerxuntuoheti, Peter Mende-Siedlecki

Rowan-Virtua Research Day

Healthcare equity is an essential right, and while the quality of care is assumed to be uniform, notable disparities in care are associated with factors of race, gender, and weight-particularly in the domain of pain evaluation and care. In experimental work, target race and gender have varying, and interacting effects on visual thresholds for perceiving painful expressions. Racial bias in pain perception is well established as participants see pain on black faces less readily than pain on white faces; gender also impacts pain treatment, where women are susceptible to having their pain discredited. Across two experiments, the influence of weight …

Pathways Beyond Performance: How Curriculum Style Impacts Emotional Intelligence And Interpersonal Communication In Medical Students, Dan Yacubovich, Jonathan Tadros, Jennifer Fischer, Dana Zambito

Rowan-Virtua Research Day

Background: Medical schools employ various curricula to foster medical knowledge and professional competencies. Emotional intelligence (EQ)—the capacity to manage emotions and interpersonal relationships—is essential in clinical care. While research links EQ to academic and communication skills in nursing and international medical students, limited data exist for U.S. medical students, particularly regarding curriculum type.

Objective: This study evaluates whether different curricula—Problem-Based Learning (PBL) and Synergistic-Guided Learning (SGL)—are associated with differences in EQ and interpersonal communication skills (ICS) at Rowan-Virtua SOM.

Methods: EQ was measured using the MySkills Profile (EIQ16). ICS scores were derived from standardized patient encounters in the pre-clinical years. …

Patient Education And Health Literacy Effects On Statin Use And Adherence, Ian M. Smith, Richard G. Olarsch, Alison M. Mancuso

Rowan-Virtua Research Day

Background: While the use of statins (HMG-CoA reductase inhibitors) plays a significant role in the prevention of cardiovascular disease, it is estimated approximately 60% of patients who would benefit from a statin are receiving these medications. Current research suggests that a preference for life-style intervention over medical management, concern over medical adverse reactions, and a lower perceived risk of cardiovascular events is associated with statin non-adherence.

Methods: An IRB-approved paper survey was administered to patients aged 18 to 89 at an ambulatory primary care clinic for non-acute visits. Qualtrics was utilized to collect, store, and process data. Information elicited from …

Acetylcholine Release In The Dorsal Lateral Straitum During Social Approach Task, Taylor Good, Oyku Dinckol, Noah Wenger, Jake Caselli, Munir Gunes Kutlu

Rowan-Virtua Research Day

Nicotine Decreases ACh Release in the DS leading to a Serenic Effect during Social Approach Task

Acetylcholine (ACh) regulates attention, learning, and stress responses (Benarroch E. E., 2012). The dorsal striatum (DS), essential for stimulus-response learning, is also linked to anxiety and compulsivity (Casado-Sainz et al., 2021). We used behavioral pharmacology and in vivo fiber photometry to study ACh responses during social approach tasks in the dorsal striatum. Male and female C57BL/6J mice underwent stereotaxic surgeries to inject a fluorescent ACh sensor (ACh.Sn.Fr) and implant fiber optic cannulas in the DS. Using in vivo fiber photometry, we tracked ACh release …

Barriers To Care For Neonatal Abstinence Syndrome In Southern New Jersey, Gabriela Taslitsky, Hijab Zaidi, Nafisa Zalil

Rowan-Virtua Research Day

Neonatal Abstinence Syndrome (NAS) is a spectrum of clinical manifestations seen in newborns due to withdrawal secondary to intrauterine illicit and/or prescription drug exposure. Newborns with NAS present with common signs of withdrawal such as poor feeding, irritability, seizures, hypertonicity, low birth weight, loose stool, and premature birth. Maternal opioid use is the most common cause of NAS and with the increase in opioid use in the past decade the cases of NAS have also increased. This study examines the prevalence and challenges associated with NAS in Southern New Jersey. Our analysis reveals that Atlantic and Gloucester counties reported the …

Modulation Of Opioid Receptor Expression In The Ventral Tegmental Area Following Stress Exposure In Rats, Maya Patel, John Tkaczynski, Jordan Riser, Nicole Shellenbarger, Jin Park, Daniel Manvich, Daniel J. Chandler

Rowan-Virtua Research Day

Background: The ventral tegmental area (VTA) contains dopamine-producing neurons projecting to various brain regions. VTA dysfunction is linked to addiction and depression. Delta opioid receptor upregulation relates to chronic pain, inflammation, cancer, and early adversity. Kappa receptors in the VTA influence stress, drug-seeking, mood, and reward. Notably, chronic substance abuse upregulates the κ-receptor/dynorphin system, and the opioid system regulates social interaction needs.

Hypothesis: Stress will upregulate opioid receptors.

Methods: We compared group-housed and individually-housed rats using stress tests, analyzing behavior and quantifying VTA opioid receptor expression.

Results: Social isolation upregulated delta and kappa opioid receptors in …

Measuring The Strategies To Cope With Shift Work Among Healthcare Workers, Khushi Mehta, Lindsay Ham

Psychological Science Undergraduate Honors Theses

It is known that lack of sleep, no matter what career a person is in, is detrimental to the overall longevity and health of an individual. Balance of sleep can be easy to attain, especially if one’s work life is able to facilitate it. Healthcare workers, however, often do not have that luxury. Healthcare professionals work a variety of shifts ranging from night shifts, 12-16-hour shifts, regular daytime hours, and being on call during the night. These irregular working schedules can have a detrimental effect on their sleep quality and quantity. If healthcare workers don’t get enough sleep, it can …

Men’S Fertility Beliefs, Intentions, And Contraceptive Use, Meagan Kunitzer

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

Despite advancements in reproductive technology, gender-inclusive approaches remain limited, and research on men’s reproductive health is scarce. Specifically, little is known about how men conceptualize reproductive health and how perspectives vary by race and social class. As such, the purpose of this study is to further the field’s understanding of men’s reproductive health, including fertility beliefs, intentions, and behaviors. Guided by the theory of conjunctural action, this study uses survey-driven narrative construction to explore how 35 men think about their reproductive health and how this varies by race and class. The main benefit of using this method is that it …

Methods: This secondary analysis utilizes data from 242 patients (191 FTD, 51 AD) who took part in a collaborative study between the University of California, Berkeley, and the University of California, San Francisco. Preparatory physiological responses were measured as heart rate increases from a baseline to an instruction period, when participants were informed that they were about to watch an emotional film. Behavioral symptoms, including eating behaviors, were assessed using the Neuropsychiatric …

From Trauma To Treatment: Chronic Neurobehavioral Consequences And Emerging Treatments, Moriah E. Mcguier

Dartmouth College Ph.D Dissertations

Severe trauma exposure related to traumatic brain injury (TBI) or psychiatric disorders like post-traumatic stress disorder (PTSD) leads to neurobehavioral and physiological impairments that reduce the quality of life of individuals and remain difficult to treat with current therapeutic options. Further, these conditions are highly comorbid, notably in PTSD with blast-traumatic brain injury (bTBI) commonly experienced by military members via explosive forces, leading to complex and heterogenous outcomes. To address this, preclinical models have been developed to recapitulate aspects of TBI and PTSD. This thesis utilizes two such models in rats, bTBI and the single prolonged stress (SPS) model for …

Mechanisms Of Behavioral Change In Hosts Of Toxoplasma Gondii: A Review, Olivia Grimsley

Senior Honors Theses

The parasite Toxoplasma gondii is a highly ubiquitous parasite that latently infects an estimated 33% percent of the global population. Toxoplasmosis is of obvious clinical significance due to the extremely high risks to the unborn who contract it congenitally. Less attention has been given to a more subtle aspect of latent infection, which is the behavioral alterations that are commonly experienced by those who contract the parasite. Infected individuals commonly display a variety of altered behaviors, such as increased aggression and risk-seeking behaviors, depression, higher tendency towards suicide and self-directed violence, a loss of fear response, and a greatly increased …

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 …

A Psychometric Evaluation Of The Intentionality Bias Task, David Willard

Graduate Theses and Dissertations (2019 - present)

Intentionality Bias Task (IBT) provides quick and easy assessment of the tendency to overattribute intentionality to the behaviors of others. The IBT has been used repeatedly in research that has attempted to connect intentionality bias to a wide range of disorders and socio-emotional abilities, including schizophrenia spectrum disorder, autism spectrum disorder, and cognitive empathy. To date, however, there has been no systematic examination of the IBT’s psychometric properties. The present study attempts to fill this gap by testing whether the IBT possesses a reliable factor structure. Specifically, the 34 items of the IBT were written to reflect two types of …

Psychological Treatment Behind The Walls:Insights From The Inside, Rogelio Serrano

Psychology Division Scholarship

Repeated eras of mass incarceration, criminalization of marginalized communities, and substance use policies have created a revolving door of justice involved populations. The ever-increasing prison population has repeatedly become the largest contingency of mental health clientele for an overburdened mental health system. Those who work with formerly incarcerated individuals in the community often don’t know the unique set of challenges faced by practitioners within the system. Increased understanding and coordination of care can offer opportunities for sustained recovery and reduced levels of recidivism. In this presentation participants will learn about the unique insights on mental health treatment that can be …
