Characterization Of Left-Ventricular Thrombus Formation Using High Frequency Ultrasound, Kelsey A. Bullens, Arvin H. Soepriatna, Pavlos P. Vlachos, Craig J. Goergen

The Summer Undergraduate Research Fellowship (SURF) Symposium

Heart failure is a leading cause of death in the United States, and cardiac thrombus, a common morbidity associated with heart failure, significantly increases a patient’s risk of embolic events. The objective of this project is to characterize left-ventricular (LV) thrombus development using high frequency ultrasound imaging in a murine model. C57BL/6J wild-type mice (n=6) were injected intraperitoneally with iron dextran five times a week for six weeks to increase oxidative stress in the heart. Granulocyte-colony stimulating factor (G-CSF) was subcutaneously injected daily during the second week to initiate stem cell migration and stimulate endothelial cell activation, thus increasing the …

To What Extent Did Blood Transfusion Systems And Technologies Modernize During World War Ii?, Hannah J. Leblanc

Young Historians Conference

This investigation will explore changes in blood transfusion during World War II (1939-1945). Medical technology and collection systems for whole blood and blood plasma in particular will be examined. The focus of this investigation will be the United States, but Great Britain will also be mentioned due to its close blood transfusion-related interactions with the United States during this period. Additionally, blood transfusion prior to World War II and in modern times will also be considered in this investigation to provide context and to allow assessment of modernization during the war. However, artificial blood substitutes will not be considered, nor …

Effects Of Antiepileptic Medications On Bone Density In Individuals With Intellectual And Developmental Disabilities, Carly R. Gregory, Hannah L. Stedge, Robyn K. Brandenburg

The Research and Scholarship Symposium (2013-2019)

Individuals with intellectual and developmental disabilities (IDD) are commonly prescribed antiepileptic drugs (AEDs) to manage seizures, manage behavior, and stabilize mood. Though research has been done on the effects of antiepileptic medications in patients with epilepsy, little study has been done on the persons with intellectual and developmental disabilities population. After surveying IDD patients with a history and current use of AEDs on osteoprotective behaviors, we were unable to use SPSS due to incomplete surveys and low sample sizes. However, we were still able to analyze for common themes, and we found that the most prevalent use of AEDs was …

Volume Averaging Of Spectral-Domain Optical Coherence Tomography Impacts Retinal Segmentation In Children, Carmelina Trimboli-Heidler, Kelly Vogt, Robert A. Avery

GW Research Days 2016 - 2020

Purpose: To determine the influence of volume averaging on retinal layer thickness measures acquired with spectral-domain optical coherence tomography (SD-OCT) in children.

Methods: Macular SD-OCT images were acquired using three different volume acquisition settings (i.e., ART 1, 3, and 9 volumes) in children enrolled in a prospective OCT study. Total retinal, retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, inner nuclear layer, and outer plexiform layer thicknesses were measured around an ETDRS grid using beta version automated segmentation software for the Spectralis. The magnitude of manual segmentation required to correct the automated segmentation was classified as …

Severity Of Pain Is Not Associated With Urgency Of Diagnosis In Ed Patients With Abdominal Pain, Ryan Brunetti, Caitlin David, Lorna Richards, Melissa J. Mccarthy, Andrew C. Meltzer

GW Research Days 2016 - 2020

Background

Abdominal Pain is the most common cause of visits to US Emergency Departments (EDs) and the causes range from urgent to non-urgent diagnoses. Distinguishing urgent versus non-urgent causes of abdominal pain is done through the use of clinical exam, lab studies and diagnostic imaging such as CT scans. There are no validated clinical decision rules to assist physicians in discriminating urgent from non-urgent causes of abdominal pain or which patient needs a CT scan. There is controversy regarding the use of CT scans for patients with abdominal pain due to the increased cost, radiation exposure and length of stay. …

Spectral Changes Caused By Radiofrequency Ablation Of Cardiac Tissue, Mohammed Aljishi, Huda Asfour, Luther Swift, Narine Muselimyan, Marco A. Mercader, Narine Sarvazyan

GW Research Days 2016 - 2020

New diagnostic catheters can be developed by delivering and acquiring light through a small fiberoptic bundle. This can provide a useful real time feedback guidance to observe tissue damage caused by thermal injury used to treat cardiac arrhythmias. Yet, little is known about the exact spectral changes caused by radiofrequency ablation (RFA) in different types of cardiac tissue. We hypothesized that the most sensitive optical ranges for characterizing thermal injury can be revealed by comparing spectral information from different areas of the heart before and after RF ablation. Freshly excised porcine hearts were used to acquire and analyze excitation emission …
