Assessing The Impact Of Knowledge-Based Planning On Dosimetric Performance In Adaptive Prostate Sbrt Planning, Kayla Kenny

Masters Projects

Daily adaptive prostate stereotactic body radiation therapy (SBRT) is now feasible with advances in adaptive radiotherapy and automated optimization. However, the dosimetric quality of Ethos Intelligent Optimization Engine version 2 (IOE v2) automated plans may vary because optimization is based on user-defined templates rather than patient-specific dose guidance. This retrospective study evaluated whether integrating RapidPlan knowledge-based planning (KBP)–derived optimization objectives into the Ethos IOE v2 adaptive planning workflow improved dosimetric quality for prostate SBRT. Fifteen intact prostate SBRT patient datasets were evaluated. For each patient, three plans were generated: a baseline Ethos IOE v2 reference plan (Ref), a plan incorporating …

Id-More Vision: Real-Data Machine-Learning Assessment For A Digital-Twin-Inspired, Xr-Ready Rehabilitation Prototype, Rickey L. Clark

Master's Theses

Rehabilitation assessment often relies on periodic observation, while many XR prototypes show scripted rather than recorded-motion evidence. iD-MORE Vision is an offline pipeline trained on KIMORE and IRDS and linked through JSON packets to a two-mode Unity desktop prototype. Both datasets include controls and rehabilitation participants with neurologic, musculoskeletal, or mobility impairments. This improves relevance but does not clinically validate the system.

Under fixed subject-wise splits, the primary five-seed Random Forest predicted KIMORE clinician scores with MAE 6.087 ± 0.044 cTS and R² 0.568 ± 0.006; the subject-level R² interval crossed zero. The primary IRDS five-run CUDA GRU averaged 0.877 …

Hyposense: Multimodal Physiologic And Voc Wearable For Early Hypoglycemia Detection, Nidhi R. Patel

Honors Theses

Hypoglycemia remains a significant safety concern for insulin-dependent individuals, especially when blood glucose declines rapidly during exercise, sleep, or periods of impaired hypoglycemia awareness. Current continuous glucose monitors and automated insulin delivery systems have helped to improve diabetes management, but these technologies primarily respond to glucose trends after they have already started and may not actually provide sufficient warning before symptoms occur. This thesis describes the development of HypoSense, a noninvasive wrist worn wearable concept that is designed to support earlier hypoglycemia risk detection through multimodal physiologic and volatile organic compound emission sensing. HypoSense combines volatile organic compounds/gas sensing with …

Impact Of S-Phase Kinase Protien 2 Blockades On Hematopoetic Stem Cell Metabolism, Nicole Elmaraghy

Electronic Theses, Projects, and Dissertations

Hematopoietic stem and progenitor cells (HSPCs) quiescence is vital for the success of bone marrow transplantation, as it preserves long term self- renewal and prevents premature exhaustion (Takubo et al., 2013; Wilson et al., 2008). However, bone marrow transplant (BMT) failure remains a clinical challenge, often due to lack of long-term engraftment and insufficient stress reliance. Both of these characteristics are tightly linked to disrupted stem cell quiescence and metabolic imbalance (Anso et al., 2017; Vannini et al., 2016). One key player is S-phase kinase protein (SKP2), an E3 ubiquitin ligase that targets cell cycle inhibitors, like p27, for proteosome …

This study aimed to evaluate the use of fecal egg counts (FEC) as a non-invasive and efficient method for estimating the worm burdens of these parasites in laying hens. A flock of 12 brown egg laying, spent, hens were individually penned on concrete. Fecal samples (both cecal and intestinal) …

Pseudomonas Aeruginosa Exoenzyme Y Enzymatic Activity Inhibits Exoenzyme S-Induced Caspase Activation But Not Cytotoxicity In Pulmonary Microvascular Endothelial Cells, Connor Holm

Honors Theses

Pseudomonas aeruginosa (P. aeruginosa) is the most common cause of ventilator-associated pneumonia in intensive care unit patients. P. aeruginosa utilizes a type III secretion system that injects exoenzymes U, S, T, and/or Y into the host cell cytosol. A majority of clinically isolated P. aeruginosa strains express ExoY often in combination with ExoU and ExoT, or ExoS and ExoT. Host signaling mechanisms in response to intoxication with individual exoenzymes have been extensively studied, yet little is known about host cell response to co-intoxication. In this study, pulmonary microvascular endothelial cells (PMVECs) were infected with P. aeruginosa strains expressing different combinations …

Using Visual Prompts To Analyze Ejection Fraction In Echocardiograms, Kevin Reisch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Left ventricular ejection fraction (LVEF) is a critical biomarker for heart failure, but manual estimation from echocardiograms is time-consuming. Artificial intelligence can be used to accelerate this process, allowing clinicians to focus on other critical tasks. Current methods typically train models from scratch on echocardiogram datasets; however, this approach is limited by the scarcity of large medical imaging datasets, which are expensive and difficult to acquire. We present a transfer learning approach that leverages pretrained models from massive datasets, enabling continuous improvement as foundation models advance. Our method employs visual prompting to generate trainable masks for echocardiogram videos, transforming the …

Introducing An Eating Disorder Protocol In The Pediatric Primary Care Setting, Brandi Bozarth

DNP Projects

Background: The incidence of eating disorders has been on the rise, often beginning in adolescence and continuing well into adulthood. Consequences of untreated disrupted eating patterns can affect multiple body systems and are responsible for thousands of deaths annually. Despite these facts, research and data regarding eating disorders in adolescent patients are severely deficient. There is also a lack of standardization regarding assessing eating disorders in the pediatric primary care setting, as there are no specific guidelines or screening processes recommended by the American Academy of Pediatrics for the detection of eating disorders.

Purpose: The purpose of this project is …

5-Fluorouracil Induced Oxidative Stress Is Variable Across Triple Negative Breast Cancer Cell Lines, Rachel L. Walker

Departmental Honors & Graduate Capstone Projects

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with treatment limited to chemotherapy. However, not all patient tumors respond to chemotherapy. The variable cytotoxic effects of chemotherapies may be due to how cancer cells regulate reactive oxygen species (ROS). In this study, we examined two mouse breast cancer cell lines: 4T1 and EO771, vary when treated with hydrogen peroxide (H2O2) and 5-Fluorouracil (5FU), known ROS-inducing substances. In 4T1 cells H2O2 increased oxidized DNA but caused minimal cell death. While in EO771 cells that same amount of H2O2 caused complete apoptosis. Cell number, ROS, and cell death showed …
