Identification Of Candidate Microbial Biomarkers Of Disease And Design Of Engineered Microbial Therapeutics For The Gut Microbiome, Aura Lucia Ferreiro

McKelvey School of Engineering Theses & Dissertations

The human gut microbiome is a compositionally and functionally diverse community of microorganisms that profoundly influences the health of the host. Deep characterization of gut microbiomes via high-throughput sequencing has identified associations between the gut microbiome and disease states, and spurred development of engineered microbial therapeutics. Successful translation of these research efforts to the clinic will involve i) consideration of how engineered microbes behave and adapt in the gut, towards the implementation of biosafety mechanisms, and ii) identification and validation of microbial biomarkers of disease. This dissertation describes both investigative (Chapter 2) and engineering (Chapters 3 and 4) approaches to …

Deep Learning Applications In Medical Bioinformatics, Ziad Omar

After a patient’s breast cancer diagnosis, identifying breast cancer lymph node metastases is one of the most important and critical factor that is directly related to the patient’s survival. The traditional way to examine the existence of cancer cells in the breast lymph nodes is through a lymph node procedure, biopsy. The procedure process is time-consuming for the patient and the provider, costly, and lacks accuracy as not every lymph node is examined. The intent of this study is to develop an artificial neural network (ANNs) that would map genetic biomarkers to breast lymph node classes using ANNs. The neural …

The state of Kentucky has the highest cancer incidence and mortality in the United States. High‐risk populations such as this are often underrepresented in clinical trials. The study aims to do a comprehensive analysis of molecular landscape of metastatic cancers among these patients with detailed evaluation of factors affecting response and outcomes to immune checkpoint inhibitor (ICI) therapy. We performed a retrospective analysis of metastatic solid tumor patients who received ICI and underwent molecular profiling at our institution.

Sixty nine patients with metastatic solid tumors who received ICI were included in the study. Prevalence of smoking and secondhand tobacco exposure …
