Deep Phenotyping: Symptom Annotation Made Simple With Sams., Robin Steinhaus, Sebastian Proft, Evelyn Seelow, Tobias Schalau, Peter N Robinson, Dominik Seelow

Faculty Research 2022

Precision medicine needs precise phenotypes. The Human Phenotype Ontology (HPO) uses clinical signs instead of diagnoses and has become the standard annotation for patients' phenotypes when describing single gene disorders. Use of the HPO beyond human genetics is however still limited. With SAMS (Symptom Annotation Made Simple), we want to bring sign-based phenotyping to routine clinical care, to hospital patients as well as to outpatients. Our web-based application provides access to three widely used annotation systems: HPO, OMIM, Orphanet. Whilst data can be stored in our database, phenotypes can also be imported and exported as Global Alliance for Genomics and …

Frailty And Neurocognition In Prostate Cancer, Lindsey Hanson

Theses & Dissertations

Prostate cancer (PCa) treatment often leads to distressing side effects ranging from muscle loss, physical inactivity, and fatigue to cancer associated cognitive decline (CACD). Evidence suggests that men treated with androgen deprivation therapy (ADT) may have a specifically high risk of CACD, partially due to increased frailty. However, the current literature on cognitive effects of ADT is equivocal. Therefore, the primary objectives of this study were to (1) compare cognitive function, physical activity (PA), and fitness in men receiving ADT, men scheduled to receive radiation, and men under active surveillance for PCa; (2) examine changes in cognitive performance and PA …

Leukocyte Subsets In The Peripheral Blood And Spleen Of Gastrointestinal Cancer Patients, Kathryn E. Cole

Theses & Dissertations

In 2022, an estimated 62,210 people will be diagnosed with pancreatic ductal adenocarcinoma (PDAC) and approximately 49,830 will die from the disease. Current treatment strategies for gastrointestinal (GI) cancer patients, such as PDAC, have shown limited benefit, suggesting the need to develop novel, multimodality therapeutic approaches. Adoptive cellular therapy (ACT) using autologous tumor infiltrating lymphocytes (TILs) has shown efficacy in patients with melanoma; however, this approach is costly and requires extensive cell culture for sufficient numbers of T-cells for infusion. GI cancer patients with borderline resectable disease, whose primary tumor is adjacent to the splenic vasculature, can sometimes undergo a …

The Role Of Calprotectin In T-Lymphocyte Driven Inflammation In A Mouse Model Of Psychological Trauma, Cassandra Moshfegh

Theses & Dissertations

Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder that affects nearly 45 million Americans. This mental disorder is characterized by behavioral symptoms such as learned helplessness, hyperarousal, withdrawal, and flashbacks. The deleterious effects of PTSD are far-reaching and go beyond behavioral dysfunction, as these individuals are at a three-fold higher risk of comorbid inflammatory diseases. Autonomic, metabolic, and cardiovascular diseases plague these individuals later in their lifetime, however, the mechanistic link connecting psychological trauma to this systemic peripheral immunological dysfunction remains elusive. T-lymphocyte-induced inflammation plays a significant role in all these disease pathologies. Previous work from our laboratory demonstrated …

Innate Immunity In The Pathobiology And Treatment Of Infectious And Neurodegenerative Diseases, Mai Mostafa

Theses & Dissertations

Mononuclear phagocytes (MPs; monocytes, macrophages, and dendritic cells) are the governors of innate immunity which is the body’s first line of defense against microbial pathogens. They act beneficial or detrimental. They are crucial for an effective non-specific immune response to invading pathogens by engulfing, destroying, then eliciting an adaptive specific immune response. Given their pivotal functions in the host immune defense, studying MP immune responses in disease is paramount important for understanding disease pathobiology and uncovering therapeutic strategies.

Th1, Th2, And Th17 Inflammatory Pathways Predict Cardiometabolic Protein Expression In Serum Of Covid-19 Patients, James Richard Michels

Honors Theses

A predominant source of complications in SARS-CoV-2 patients arises from severe systemic inflammation contributed to by Helper T-cell associated cytokines, potentially leading to tissue damage and organ failure. The high inflammatory burden of this viral infection often results in cardiovascular comorbidities. A better understanding of the interaction between the cytokine storm and cardiovascular proteins might inform medical decisions and therapeutic approaches. We hypothesized that all major helper T-cell inflammatory pathways (Helper T 1, Helper T 2 and Helper T 17) synergistically contribute to cardiometabolic pathways in serum of COVID-19 patients, and that both of these factors correlate to COVID-19 severity. …

Gut Commensals Modulate Siv/Shiv Pathogenesis And Therapeutics, Samuel Johnson

Theses & Dissertations

Despite significant advancements in combination antiretroviral therapy (cART), ongoing inflammation in the brain and gut remain two of the most significant hurdles in the health of people living with human immunodeficiency virus (HIV). Additionally, a viral reservoir in each compartment inhibits cure efforts by allowing rapid viral rebound following cART interruption. Emerging understanding of the gut-brain axis (GBA) implicates each compartment in the modulation of the other in a complex bi-directional interaction mediated by vagus innervation, circulating lymphocytes, and microbiome composition and biproducts. Using multiple models of the simian (and simian-human) immunodeficiency virus (SIV/SHIV) and therapeutic intervention, I present how …
