The Role Of Ect In Ocd: A 10-Year Review (2014-2024), Mariana Sales, Tainiz Polanco, Amy Nguyen

Rowan-Virtua Research Day

Background: Obsessive-compulsive disorder (OCD) affects up to 2.5% of the population with significant impacts on everyday functioning and relationships. First-line treatment includes selective serotonin reuptake inhibitors (SSRI) and cognitive behavioral therapy; however, studies have found that up to 40-60% of patients do not respond to SSRIs. ECT is an alternative approach that has demonstrated limited efficacy in OCD.

Objective: The current review aims to summarize the results of published work between 2014-2024 to assess the efficacy of ECT in the treatment of OCD.

Methods: A literature review was conducted using eight studies from 2014-2024 to assess the effectiveness of ECT …

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.

Identifying Early Presentation Of Serotonin Syndrome In A 20-Year-Old Male Prescribed Clomipramine And Quetiapine: A Case Report, Veronica Alday, Justin Scarano, Jonathan Yuh, Christie Richardson

Rowan-Virtua Research Day

Serotonin syndrome, a potentially life-threatening condition, can be challenging to diagnose due to its diverse etiology and varied symptomatology. Despite its severity, serotonin syndrome may present from mild to fatal, with symptoms such as autonomic instability, altered mental status, and neuromuscular excitation (e.g. muscle rigidity, hyperreflexia). Here, we present a 20-year-old male with an extensive psychiatric history who was prescribed clomipramine and developed serotonin syndrome. Few cases of serotonin syndrome have been reported to date, exacerbating the difficulty in recognizing and quickly treating such cases. Cases of serotonin syndrome should continue to be reported, in order to familiarize clinicians with …

The Anxiolytic Effects Of Ashwagandha Supplementation In Adults With Autism Spectrum Disorder And Anxiety, Jessica Mitchell, Andrea Iannuzzelli, Wendy Aita

Rowan-Virtua Research Day

BACKGROUND: The neuroendocrine system activates the hypothalamus-pituitary-adrenal (HPA) axis during stress,1 and individuals with autism spectrum disorder (ASD) may have atypical stress responses linked to HPA axis dysregulation.2 Prolonged activation of this system increases cortisol secretion, the body’s primary stress hormone.3 Withania somnifera (Ashwagandha) is a traditional herbal remedy believed to reduce stress by modulating the HPA axis and lowering cortisol levels.5

HYPOTHESIS: Following four weeks of Ashwagandha supplementation, the treatment group is expected to exhibit reduced cortisol levels, improved Aberrant Behavior Checklist (ABC) scores, and decreased stress-related behaviors, reflecting its anxiolytic effects.

METHODS: Forty-two adult participants with ASD and …

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 …

The Correlation Between A Methylenetetrahydrofolate Reductase Deficiency In Autism Spectrum Disorder Patients And The Presence Of Mental Health Disorders, Hinal Joshi, Andrea Iannuzzelli

Rowan-Virtua Research Day

• Currently little literature exists on connection between Methylenetetrahydrofolate reductase (MTHFR) deficiency and mental health disorders

• Reduced enzyme activity associated with certain MTHFR variants contributes to altered folate metabolism, elevated homocysteine levels, and disrupted DNA methylation, all of which are implicated in mental health disorders

• Identifying genetic risk factors could facilitate earlier diagnosis and intervention, leading to improved outcomes

• Relevant results could help reduce stigma and promote greater understanding of challenges faced by patients on the spectrum

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 …

Child Sex Trafficking In Pediatrics: From Screening To Comprehensive Care, Victoria Shwe, Tracy Lin, Nicole M. Leopardi

Rowan-Virtua Research Day

Child sex trafficking is a significant issue in New Jersey, with minors making up 22% of trafficking victims in 2023. While screening tools exist to identify at-risk youth, there is a major gap in understanding the steps healthcare providers should take after identification to ensure appropriate care, support, and referrals. Current research highlights the lack of data on the use of trafficking screening tools and the absence of standardized post-screening protocols. Most pediatricians rely on referrals to social services or law enforcement, yet limited coordination between healthcare providers and these agencies complicates effective care. The shortage of child abuse pediatric …

Beyond The Label: Understanding And Addressing Occupational Stigma In Psychiatry, Mahesh Vasudevan, Madeeha Sheriff

Screening And Prevention Of The Female Athlete Triad, Lia Summer Goldberg, Kate Whelihan

Rowan-Virtua Research Day

Background The Female Athlete Triad—a syndrome of low energy availability, menstrual dysfunction, and decreased bone mineral density—poses a significant risk to female athletes, particularly those in sports emphasizing leanness or endurance. Despite its potential to impair both performance and long-term health, the Triad remains frequently underdiagnosed due to stigma, nonspecific symptoms, and limited screening practices. This review investigates current strategies for screening and preventing the Triad, aiming to identify best practices and areas needing improvement.

Methods A literature review was conducted using PubMed, focusing on studies published after 2005. Keyword searches included “female athlete triad screening,” “prevention,” “education,” and “awareness.” …

Case Report: Lamotrigine-Induced Rash In An Adult Patient, Dhruvin Patel, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Lamotrigine (Lamictal®) is a commonly prescribed anticonvulsant and mood-stabilizing medication. One of the rare but serious adverse effects of lamotrigine is the development of a drug-induced rash, which can be potentially life-threatening. This case report highlights the occurrence of a drug-induced rash in a 33-year-old female patient who was prescribed lamotrigine for the management of bipolar disorder. The patient presented with a characteristic rash, and following timely intervention, the rash resolved without complications. This case emphasizes the importance of monitoring for early signs of rash in patients receiving lamotrigine and outlines management strategies.

Venlafaxine Exposure In Pregnancy And Its Association With Pre-Eclampsia Development, Jhanvi Patel

Posters

Venlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), is widely used to manage depression and anxiety, including in pregnant women. However, its known hypertensive side effects raise concerns about a potential link to pre-eclampsia, a serious pregnancy complication characterized by new-onset hypertension and proteinuria. Pregnant women with psychiatric disorders already have an increased risk of hypertensive disorders, and while untreated depression can lead to adverse outcomes such as preterm birth and fetal cortisol elevation, the safety of venlafaxine remains uncertain. Current research lacks wellcontrolled studies assessing its association with hypertensive complications in pregnancy. This systematic review aims to evaluate whether venlafaxine use …

Neuroimaging-Based Variability In Subtyping Biomarkers For Psychiatric Heterogeneity, Zhenfu Wen, Mira Z Hammoud, Carole E Siegel, Eugene M Laska, Duna Abu-Amara, Amit Etkin, Mohammed R Milad, Charles R Marmar

Faculty, Staff and Student Publications

Neuroimaging-based subtyping is increasingly used to explain heterogeneity in psychiatric disorders. However, the clinical utility of these subtyping efforts remains unclear, and replication has been challenging. Here we examined how the choice of neuroimaging measures influences the derivation of neuro-subtypes and the consequences for clinical delineation. On a clinically heterogeneous dataset (total n = 566) that included controls (n = 268) and cases (n = 298) of psychiatric conditions, including individuals diagnosed with post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), and comorbidity of both (PTSD&TBI), we identified neuro-subtypes among the cases using either structural, resting-state, or task-based measures. The …

Faculty, Staff and Students Publications

Obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) share overlapping features for which similar cognitive behavioral treatment (CBT) strategies can be employed. However, the comorbid presence of these conditions poses unique clinical considerations, and a nuanced approach to assessment, conceptualization, and treatment is needed when working with individuals with co-occurring OCD and PTSD. Treatment providers may not be aware of these nuances and may hold misconceptions about co-occurring OCD and PTSD, impacting their approach to assessment, conceptualization, and treatment. The current study sought to examine possible misconceptions among mental health treatment providers of differing specializations. Among 146 primarily CBT-oriented treatment …

Circulating Epstein-Barr Virus Antibody Levels As A Biomarker Of Socioecological Adversity In Amazonian Ecuador, Tyler M Barrett, Melissa A Liebert, Geeta N Eick, Julia G Ridgeway-Diaz, Felicia C Madimenos, Aaron D Blackwell, Tara J Cepon-Robins, Samuel S Urlacher, Lawrence S Sugiyama, J Josh Snodgrass

Faculty, Staff and Students Publications

Objectives: Circulating Epstein-Barr virus antibodies (EBV-Ab) are used as a biomarker of chronic stress in high-income settings, but their relevance in environments with a high burden of infectious disease, nutritional constraints, and limited resources is less clear. We investigated EBV-Ab as a biomarker of adversity in a setting where local ecology and economy may affect immune development differently than in wealthy countries.

Methods: We measured EBV-Ab in finger-prick dried blood spots collected from Indigenous Shuar (n = 433) and non-Indigenous Colonos (n = 84) ranging from < 1 to 87 years old in Amazonian Ecuador. For a subset of adults (≥ 15 years, n = 210), we collected socioeconomic information (income, education, and occupation) and assessed household-level market integration. We determined the most important predictors of EBV-Ab for adults and children using multi-model averaging of linear regression models.

Results: Male children (< 15 years) had lower EBV-Ab than female children (model averaged β [SE]: -0.238 [0.066]). For adults, Shuar had higher EBV-Ab than Colonos (model averaged β [SE]: 0.235 [0.113]), and high systolic blood pressure was an important predictor of elevated EBV-Ab (model averaged β [SE]: 0.088 [0.047]). Individuals who reported unpaid domestic work as their primary occupation had higher EBV-Ab than agricultural workers (model averaged β [SE]: 0.302 [0.113]). Individuals living in houses with more market-sourced infrastructure had lower EBV-Ab (model averaged β [SE]: -0.088 [0.068]).

Conclusions: Circulating EBV-Ab may capture context-specific aspects of socioecological adversity …

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 …

Department of Psychiatry and Human Behavior Faculty Papers

Introduction: Among U.S. adults, over 3 million report a history of epilepsy, accounting for nearly 1.2% of the population. Sleep deprivation is a well-known risk factor for increased likelihood, intensity, and length of seizures. However, the long-term impact of sleep deprivation on people with epilepsy is not well explored. The purpose of this study was to assess mortality risk among individuals with epilepsy based on sleep duration.

Methods: Data from the 2008–2018 National Health Interview Survey (NHIS) were linked with mortality data from the National Death Index (NDI) for US adults aged 65 years and older. Survival curves showed the …

The Use Of Person-Centered Language In Scientific Research Articles Focused On Psychosis, Zach Monahan, Tanner Stone, Vinay Swami, Kelly Dunn, Micah Hartwell

Journal of Patient-Centered Research and Reviews

Purpose: Societal stigma of psychosis leads to delayed treatment for individuals experiencing early symptoms, for fear of being labeled “crazy” or “psychotic.” Delayed treatment can worsen the prognosis of individuals with psychosis. Proper adherence to person-centered language (PCL) guidelines can curb the widely held stigmatized preconceptions about psychotic conditions.

Methods: Our meta-epidemiological analysis began with a systematic search of literature in PubMed discussing psychosis from 2020-2022. From the 14,522 results, we randomly selected 500 articles in journals with at least 20 articles on psychosis (n = 9,775), of which 241 articles met the inclusion criteria. These papers were screened for …

A New Paliperidone Palmitate Formulation: How Is It Different And Where Does It Fit In Our Array Of Choices For Long-Acting Formulations Of Risperidone And Paliperidone?, Justin Faden, Leslie Citrome

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Long-acting injectable (LAI) antipsychotics have been shown to enhance treatment adherence and outcomes in individuals with schizophrenia, schizoaffective disorder, and bipolar disorder. In recent years, the U.S. Food and Drug Administration (FDA) has approved several LAIs with differing amenities of care, such as mode of administration, duration of oral medication supplementation, dosing frequency, needle gauge and size, and injection volume, amongst others. Additionally, several LAIs are distinct formulations of risperidone and paliperidone, making it difficult to distinguish between formulations, and many providers are unfamiliar with these newer agents. In 2024, a once-monthly LAI formulation of paliperidone palmitate, manufactured by Luye …

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 …
