Cryptogenic New Onset Refractory Status Epilepticus (Norse) Responsive To Rituximab, Matthew David Anderson, Teryn Nogles, Soundarya Gowda

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

Objective: Discuss a case of new onset refractory status epilepticus (NORSE) in an otherwise healthy adult that had a positive outcome and suggests considering immunomodulators as first line treatment.

Background: NORSE is diagnosed when refractory status patients have no known history of seizures and an unremarkable workup. Other than antiepileptics and anesthetic coma, there are currently no established guidelines for management. Typically, IV steroids, plasma exchange, and IVIG are first line treatments. When these fail, second line immunomodulators are considered. Deciding between these agents is often arbitrary, and no particular agent has demonstrated consistently positive results. Prognosis is poor with …

Transcriptional Repressor Protein Based Macrolide Biosensor Development With Improved Sensitivity, Jayani A. Christopher

Graduate Research Posters

Macrolide antibiotics are in high demand for clinical applications. Macrolides are biosynthesized via giant assembly line polyketide synthases (PKS) which are arranged in a modular fashion. Combinatorial biosynthetic methods have been used to produce diversified macrolides by reprograming these modules and modifying tailoring enzymes required for post synthetic modifications. However it is challenging due to the size and complexity of PKSs. To overcome this challenge, new enzymes for macrolide diversification could be obtained by directed evolution where a large number of enzyme variants need to be screened. Therefore it is important to develop high throughput screening methods to identify the …

Frequency Of Genetic Polymorphisms Of Cyp2c19 In Native Hawaiian, And Asian And Pacific Islander Subgroups: Implications For Personalized Medicine, Khalifa Y. Alrajeh, Youssef Roman Dr

Graduate Research Posters

Pharmacogenetic testing, where prescriptions are tailored to the individual patient based on his/her genetic makeup, increases the ability to predict individual drug response. However, little is known about the prevalence of clinically actionable pharmacogenes in diverse populations. This study seeks to assess the prevalence of select drug-gene alleles that are implicated in the metabolism of commonly prescribed drugs, so-called Very Important Pharmacogenes (VIPs). The results of this study will fill in the gaps of knowledge of VIPs in underrepresented populations and characterize their potential risk for drug adverse events or due to their underlying genetic polymorphisms, especially in patients of …

Graduate Research Posters

BACKGROUND: Transcarotid artery revascularization (TCAR) is hybrid procedure that allows carotid stenting using direct surgical access of the carotid artery to restore blood flow through the carotid artery. It has shown the lowest perioperative stroke rate when compared with any prospective trial of transfemoral carotid artery stenting. However, intraoperative injuries related to the procedure and its management are not well characterized. We anticipate that this analysis will add qualitative insight in further characterizing adverse outcomes of this novel technology.

METHODS: The FDA maintains a database called the MAUDE (Manufacturer and User Facility Device Experience) for surveillance of all medical devices …

Modeling Longitudinal Change In Cervical Length Across Pregnancy, Hope M. Wolf, Shawn J. Latendresse, Jerome F. Strauss Iii, Timothy P. York

Graduate Research Posters

Introduction: A short cervix (cervical length < 25 mm) in the mid-trimester (18 to 24 weeks) of pregnancy is a powerful predictor of spontaneous preterm delivery (gestational age at delivery < 37 weeks). Although the biological mechanisms of cervical remodeling have been the subject of extensive investigation, very little is known about the rate of change in cervical length over the course of a pregnancy, or the extent to which rapid cervical shortening increases maternal risk for spontaneous preterm delivery.

Methods: A cohort of 5,160 unique women carrying 5,971 singleton pregnancies provided two or more measurements of cervical length during pregnancy. Cervical length was measured in millimeters using a transvaginal 12-3 MHz ultrasound endocavity probe (SuperSonic Imagine). Maternal characteristics, including relevant medical history and birth outcome data, were collected for each participant. Gestational age at delivery was measured from the first day of each woman’s last menstrual period and confirmed by ultrasound. Repeated measurements of cervical length during pregnancy were modeled as a longitudinal, multilevel growth curve in MPlus. A three-level variance structure was …

PURPOSE To assess criterion validity of the Actigraph GT9X accelerometer step-count function in adults with HFpEF via ankle, waist, and wrist placement, compared with manually counted, directly observed steps.

METHODS Six adults with HFpEF (age: 57.2 ± 9.4 y; African American: 50%; females: 100%) completed a cardiopulmonary exercise test (CPET) on a treadmill while wearing synchronized GT9X accelerometers on the ankle, …

Radiation Induces Metabolic Dysregulation In Pulmonary Fibroblasts, Josly Pierre-Louis, Margaret A. T. Freeberg, Jane K. Rebman, Thomas H. Thatcher, Patricia J. Sime

Graduate Research Posters

Rationale: Exposure of the lung to ionizing radiation, such as during radiotherapy, can result in pulmonary fibrosis (PF), which has few treatment options. PF is characterized by an accumulation of extracellular matrix proteins that form scar tissue, resulting in dyspnea, disruption of gas exchange, and even death. We and others have shown that metabolic reprogramming is a hallmark of idiopathic pulmonary fibrosis (IPF). IPF lung tissue, and lung fibroblasts treated with TGF-β, exhibit increased aerobic glycolysis with increased expression of lactate dehydrogenase A (LDHA) and excess production of lactate, leading to reduced extracellular pH that activates latent TGF-β. Here, we …

Influence Of Telephone Preoperative Evaluations On Patient Medication Compliance On Day Of Surgery, Emmanuel Magsino, Michael Jung, Olga Suarez Md

Graduate Research Posters

Patient compliance with medication instructions on day of surgery (DOS) is an important part of the preoperative assessment, as failure to comply with these may lead to serious perioperative consequences. Prior studies have shown that compliance increases with multimodal interventions. However due to the recent COVID-19 pandemic, many in-person visits transitioned to telephone visits and providers had to rely on patients to follow solely verbal instructions.

To determine medication compliance, this study compared the medication instructions provided by the VCU Preoperative Assessment Communication and Education Clinic, per chart review, with each patient’s own report of which medications they took on …

Pharmacogenomics And Ssris Appropriateness In Older Community Dwelling African Americans, Wint War Phyo, Lana Sargent, Elvin T. Price

Graduate Research Posters

Background: Depressive and anxiety disorders are among the most common illnesses experienced by older adults (age > 60). The selective serotonin reuptake inhibitors (SSRIs) are preferred class of antidepressants for these disorders due to their high efficacy and safety profiles among older adults. However, SSRIs are metabolized by highly polymorphic cytochrome P450 enzymes, specifically CYP2D6 and CYP2C19. This can lead to variable dose-response outcomes, especially among older African American population.

Objective: Analyze the frequency of CYP2D6 and CYP2C19 polymorphisms in African American older adults who are taking SSRIs and identify potential inappropriate use of SSRIs in these older adults using the …

Covid-10, Healthcare Interior Design + Provider Experience - How Does Your Space Work For You?, Ruth E.P. Deibler

Graduate Research Posters

The lack of research on healthcare staff experience and interior design of the spaces they work in is evident. A focus on staff perspective is needed, particularly staff who navigated the COVID-19 pandemic. This research seeks to capture those stories to develop further research in order to improve staff experience. The initial phase of this mixed-methods approach is a survey. Hypothetically, by placing providers at the center of qualitative research related to healthcare interior design, we can better understand existing healthcare spaces. Ideally, we can develop additional evidence-based, human-centered solutions to transform interior environments in healthcare.

Selective Gsk3b Deletion In Camk2a+ Forebrain Neurons Or Inhibition Via Tideglusib, Decreases Ethanol Consumption In C57bl/6j Mice, Sam Gottlieb, Andrew D. Van Der Vaart, Brennen O'Rourke, Michael F. Miles

Graduate Research Posters

Purpose: We previously identified glycogen synthase kinase-3 beta (Gsk3b) as a central member of a gene network highly regulated by acute ethanol in medial prefrontal cortex (mPFC) and associated with risk for alcohol dependence in humans. Further, we have demonstrated modulation of Gsk3b alters ethanol consumption in rodent models. GSK3B could thus represent a potential new therapeutic target for the treatment of alcohol use disorder (AUD). Here, we investigate the mechanisms of Gsk3b action in ethanol consumption and report preclinical evidence for the selective GSK3B inhibitor, tideglusib, as a therapeutic agent for AUD.

Methods: (1) Selective Cre-induced Gsk3b …

Influence Of Metal Sleeves In The Accuracy Of Dental Implant Placement Using Guided Implant Surgery, Coleman Adams

Theses and Dissertations

The fabrication of implant surgical guides through stereolithographic 3D printing has become a staple in dental implant guided surgery over the last couple decades. These surgical guides have typically utilized metal sleeves to assist in guidance of the drills during osteotome preparation. The metal sleeves can be costly and potentially cause deviations if improperly placed during post-processing of the guide. This research explored a novel method for the utilization of sleeve-free surgical guides by comparing the dimensional and angulational deviations between the implant guides with and without a metal sleeve. To achieve this goal, two separate aims were pursued. Our …

Exploring The Dopamine Transporter Utilizing A Two-Pronged Approach With Novel Cathinone Analogs And Mutant Dopamine Transporters, Charles B. Jones Iii

Theses and Dissertations

The dopamine transporter (DAT) is responsible for the removal of the neurotransmitter from the synaptic gap and a therapeutic target for a multitude of drugs. While the ortholog Drosophila melanogaster dopamine transporter (dDAT) and human serotonin transporter (hSERT) have resolved structures, the human dopamine transporter (hDAT) does not. A 3-D computational homology model of hDAT was constructed for the study of molecular interactions with agents within the central binding site (S1) of the transporter.

Synthetic cathiones are a class of abused stimulant drugs that primarily target DAT. Greater than 150 cathinones have been identified on the clandestine market but there …

Policies Addressing Barriers To Low-Income Women And Children’S Health Care Utilization In The United States And Kenya: The Role Of Physician Payments And Cash Transfer Programs, Muloongo Simuzingili

Theses and Dissertations

This dissertation examined two policies to improve low-income women and children’s healthcare utilization: physician payments and cash transfer programs. Higher physician payments increase the supply of healthcare services while cash transfers increase individuals’ demand for healthcare services. Cash transfer programs can improve health outcomes, yet the extent to which they are a cost-effective strategy is largely understudied. Therefore, this dissertation examines three overarching research questions:

1. Are Medicaid physician fees associated with access to substance abuse disorder (SUD) treatment among low-income women of reproductive age?
2. Do economic preferences moderate cash transfer program effects on children’s health care utilization? Evidence from a …
