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 …

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
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
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 …

Strengthening Mental Health Diagnostic Detection In Integrated Primary Care, Julia Brechbiel
Theses and Dissertations
Primary care behavioral health (PCBH) is crucial for providing mental health treatment to underserved, minority, and uninsured populations. There is a lack of knowledge about accurate mental health diagnoses at PCBH. Underdetection of mental health symptoms has the potential to worsen racial and socioeconomic disparities. Using an expert review process, I developed an abbreviated diagnostic clinical interview (ADCI) for integrated primary care. Next, patients (N = 82) completed the interview after attending PCBH appointments. According to the interview, 63.4% of participants met criteria for a diagnosis, while 64.7% received a diagnosis from their provider. A large portion of patients …

The Harm In Seeking Care: Assessing The Relationship Between Healthcare Discrimination And Healthcare Avoidance Behaviors In The Past Year And Since The Start Of The Coronavirus Pandemic In A Transgender And Gender Independent Sample, Kyle L. Mason
Theses and Dissertations
Background: Gender minorities encounter a myriad of barriers to accessing general and gender affirming healthcare. Financial disparities impacting affordability of healthcare costs and insurance-based denials for gender-affirming care are among prominent barriers discussed. Considerations of the prevalence of stigma, discrimination, and erasure of gender minority identities must not be neglected when seeking to understand healthcare accessibility and utilization in this population. Previous researchers have examined gender minority patients’ experiences of discrimination in healthcare settings and delaying care due to fear of discrimination. There is a dearth of knowledge about the relationship between lifetime exposure to varied forms of healthcare discrimination …
A Multilevel Mixed Methods Examination Of Treatment Nonadherence Among Rural Cancer Survivors, Bonny Morris
A Multilevel Mixed Methods Examination Of Treatment Nonadherence Among Rural Cancer Survivors, Bonny Morris
Theses and Dissertations
While mortality rates have been decreasing over the last 40 years, cancer remains a leading cause of death in the United States. Over 1.7 million people were diagnosed with cancer in 2019, and there were more than 600,000 cancer deaths. Of the 15 million cancer survivors in the US, nearly 3 million reside in rural areas and experience 3% higher cancer incidence and 10% higher cancer mortality compared to their nonrural counterparts. During 2006-2015, the annual age-adjusted mortality rates for all cancer sites combined decreased at a slower pace in rural areas versus nonrural areas (-1.0% vs -1.6% per year, …
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
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:
- Are Medicaid physician fees associated with access to substance abuse disorder (SUD) treatment among low-income women of reproductive age?
- Do economic preferences moderate cash transfer program effects on children’s health care utilization? Evidence from a …
Investigating Cannabinoid Type-1 Receptor (Cb1r) Positive Allosteric Modulators (Pams) In Mouse Models Of Overt Cannabimimetic Activity, Subjective Drug Effects, And Neuropathic Pain, Jayden Elmer
Theses and Dissertations
Chronic pain affects between 20 and 30 percent of the adult population in western countries and represents a wide array of specific etiologies (Berge, 2011). Neuropathic pain secondary to traumatic nerve injury, chemotherapeutic toxicity, or diseases (e.g., diabetes mellitus) is often refractory to conventional analgesics, with patients receiving less than 50% pain relief compared to placebo (Finnerup et al. 2010). The endocannabinoid system has shown potential as a therapeutic target for neuropathic pain wherein CB1 agonism via administration of exogenous agonists or pharmacological blockade of endocannabinoid catabolic enzymes exhibits efficacy in reversing allodynia in the chronic constriction injury (CCI) model …
Intermittent Theta Burst Stimulation: Application To Spinal Cord Injury Rehabilitation And Computational Modeling, Neil Mittal
Intermittent Theta Burst Stimulation: Application To Spinal Cord Injury Rehabilitation And Computational Modeling, Neil Mittal
Theses and Dissertations
Loss of motor function from spinal cord injuries (SCI) results in loss of independence. Rehabilitation efforts are targeted to enhance the ability to perform activities of daily living (ADLs), but outcomes from physical therapy alone are often insufficient. Neuromodulation techniques that induce neuroplasticity may push the limits on recovery. Neuromodulation by intermittent theta burst transcranial magnetic stimulation (iTBS) induces neuroplasticity by increasing corticomotor excitability, though this has most frequently been studied with motor targets and on individuals not in need of rehabilitation. Increased corticomotor excitability is associated with motor learning. The response to iTBS, however, is highly variable and unpredictable, …
