A Transformer-Based Deep Learning Approach For Fairly Predicting Post-Liver Transplant Risk Factors, Can Li, Xiaoqian Jiang, Kai Zhang Jan 2024

A Transformer-Based Deep Learning Approach For Fairly Predicting Post-Liver Transplant Risk Factors, Can Li, Xiaoqian Jiang, Kai Zhang

Faculty, Staff and Student Publications

Liver transplantation is a life-saving procedure for patients with end-stage liver disease. There are two main challenges in liver transplant: finding the best matching patient for a donor and ensuring transplant equity among different subpopulations. The current MELD scoring system evaluates a patient's mortality risk if not receiving an organ within 90 days. However, the donor-patient matching should also consider post-transplant risk factors, such as cardiovascular disease, chronic rejection, etc., which are all common complications after transplant. Accurate prediction of these risk scores remains a significant challenge. In this study, we used predictive models to solve the above challenges. Specifically, …


The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami Jan 2024

The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami

Adultspan Journal

This conceptual overview offers a comprehensive overview of systemic pathways that negatively impact the mental health of Black Men throughout their lives. Our argument highlights the importance for counselors and mental health professionals to utilize a thorough social risk assessment that considers these pathways in order to effectively address the mental health needs of Black Men while fostering positive working relationships. This overview strongly advocates for the use of context and structural determinants when evaluating mental health symptoms. Without an appropriate understanding of social risk and determinants, counselors may inadvertently perpetuate disparities by decontextualizing symptomology, and reproducing racist discourse.

Mathematics & Statistics Faculty Publications

The class activation map (CAM) represents the neural-network-derived region of interest, which can help clarify the mechanism of the convolutional neural network’s determination of any class of interest. In medical imaging, it can help medical practitioners diagnose diseases like COVID-19 or pneumonia by highlighting the suspicious regions in Computational Tomography (CT) or chest X-ray (CXR) film. Many contemporary deep learning techniques only focus on COVID-19 classification tasks using CXRs, while few attempt to make it explainable with a saliency map. To fill this research gap, we first propose a VGG-16-architecture-based deep learning approach in combination with image enhancement, segmentation-based region …

The Role Of Intracellular Growth During The Systemic Spread Of Listeria Monocytogenes, Jamila S. Tucker Jan 2024

The Role Of Intracellular Growth During The Systemic Spread Of Listeria Monocytogenes, Jamila S. Tucker

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Listeria monocytogenes is a facultative intracellular pathogen transmitted through the consumption of contaminated food products. Typically, infections range from mild, self-limiting gastroenteritis to life-threatening systemic infections; however, the events that occur in the gut to allow for this spread are unclear.

The focus of my thesis aims to determine how L. monocytogenes escape the mesenteric lymph nodes (MLN), the final barrier to systemic spread for both commensal and pathogenic bacteria in the gut. I have shown that intracellular replication of L. monocytogenes in an as-yet-unidentified cell type is essential for the colonization and dissemination of the bacteria from the MLN. …

Contributions Of The Replication Initiator Protein Dnaa To Physiology And Virulence Of The Lyme Disease Spirochete, Andrew Krusenstjerna

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Borrelia burgdorferi, the etiological agent of Lyme disease, is the most prevalent vector-borne disease in the United States. The spirochetal population is naturally maintained by consistently cycling between Ixodid ticks and small vertebrates. To survive within these diverse niches, B. burgdorferi has evolved a unique physiology and regulatory network to sense and respond to environmental fluxes. Replication is a hallmark of the Lyme spirochete’s enzootic life cycle, specifically at the nymphal tick-to-vertebrate interface. The mechanisms and regulatory schema for the basic cellular processes in B. burgdorferi, or indeed any member of the phylum spirochaetota, are largely unknown. The central hypothesis …

Inhibiting Pi3k/Akt To Enhance Brain Uptake Of Anticancer Agents In Glioblastoma, Louis Rodgers

Theses and Dissertations--Pharmacy

Glioblastoma (GBM) is the deadliest and most common malignant CNS tumor. Despite advances in understanding its biology and the development of targeted therapies, effective treatment options remain limited. As a result, patient survival rates are dismal, with a 5-year survival rate of only 6.8% and an overall survival of less than two years. This poor outcome is partly due to our inability to treat GBM cells that infiltrate the whole brain. Focal treatments like surgery and radiotherapy alone are insufficient due to these invasive tumor cells. Therefore, chemotherapy following resection and irradiation of the primary tumor is essential to eliminate …

Mechanistic Insight Into Maternal Electronic Cigarette Exposure And Its Effect On Offspring Cerebrovascular And Neurocognitive Health, Amber Victoria Mills

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electronic cigarettes (Ecigs) have replaced smoking within the last decade as the preferred nicotine delivery system because of their advertising to the younger populations. Marketing has sold the idea that use of Ecigs are safer than smoking and this messaging has resonated with youth and other vulnerable populations such as pregnant women. Despite over 2.8 million children under 18 (Annual National Youth Tobacco Survey) deciding to vape, there is little information about what this will do to the next generation. Further, it is that same population that will soon reach an age when they will want to have children. There …
