Spatial Pattern And Differential Expression Analysis With Spatial Transcriptomic Data, Fei Qin, Xizhi Luo, Bo Cai Ph.D., Feifei Xiao, Guoshuai Cai

Faculty Publications

The emergence of spatial transcriptomic technologies has opened new avenues for investigating gene activities while preserving the spatial context of tissues. Utilizing data generated by such technologies, the identification of spatially variable (SV) genes is an essential step in exploring tissue landscapes and biological processes. Particularly in typical experimental designs, such as case-control or longitudinal studies, identifying SV genes between groups is crucial for discovering significant biomarkers or developing targeted therapies for diseases. However, current methods available for analyzing spatial transcriptomic data are still in their infancy, and none of the existing methods are capable of identifying SV genes between …

Ecological Epidemiology Of The Fungal Pathogen Ophidiomyces Ophiodiicola In Southeastern U.S. Snake Populations: Distribution, Drivers, And Anthropogenic Risk Factors, Shivam Shukla

USF Tampa Graduate Theses and Dissertations

Studying wildlife diseases is an important conservation measure, as many pathogens are a critical threat to biodiversity worldwide. Ophidiomycosis is an emerging infectious disease caused by the invasive fungal pathogen Ophidiomyces ophiodiicola that affects a wide variety of snake species, often causing mortality. There has been limited surveillance for ophidiomycosis in the southeastern United States’ (US) snake populations and research into the effects of anthropogenic disturbance on disease spread is also lacking. Thus, this project aimed to quantify the distribution and drivers (taxonomic, anthropogenic, and morphological) of ophidiomycosis in Florida, Louisiana, and Mississippi’s free ranging snakes as well as study …

Socioeconomic Status, Obesity, Breast Cancer, And 5-Year Survival Among Men, Taye Oloruntobi Olabode

Walden Dissertations and Doctoral Studies

Although male breast cancer (MBC) is rare, affecting 2,000 men in the United States each year and comprising approximately 1% of all breast cancer diagnoses, mortality for those diagnosed with MBC is significantly higher than for women diagnosed with breast cancer. Recent research on the disparities in mortality rates between men and women revealed that there may be unexplained factors for the diagnostic disparities between men and women. Bandura’s (1986) SCT was used as the theoretical framework for this quantitative study.The purpose of this quantitative cross-sectional study was to determine whether there was an association between socioeconomic status, obesity, stage …

Life Course Stressors, Latent Coping Strategies, Alcohol Use, And Adherence Among People With Hiv, Amrita Gill, Gretchen Clum, Patricia Molina, David Welsh, Tekeda Ferguson, Katherine P. Theall

School of Medicine Faculty Publications

People with HIV (PWH) have often experienced chronic stressors across their lifespan, including adverse childhood experiences (ACES), lifetime economic hardship (LEH), and concurrent stressors associated with living in urban areas (urban stress). Prolonged exposure to stressors might result in differential coping patterns among PWH that can impact care trajectories. We utilized a life course-informed approach to examine chronic stressors as antecedents of latent coping strategies among PWH in care. High-risk alcohol use and non-adherence to anti-retroviral therapy (ART) were examined as consequences of latent coping strategies. Data were utilized from the baseline and interim follow-up visit of the New Orleans …

Baseline Factors And Their Association With Refractive Error And Control In A Pediatric Randomized Clinical Trial Of Overminus Therapy For Intermittent Exotropia, Julianne L. Robinson

USF Tampa Graduate Theses and Dissertations

Intermittent exotropia (IXT) is a condition resulting in an eye deviation away from normal alignment, potentially treatable with overminus lenses. These induce accommodation of the eye, combatting the eye drifting outward. Overminus lenses may help treat IXT but also potentially worsen refractive error. Analyses aimed to find associations of baseline factors as they relate to IXT control outcomes, as well as the risk of worsening spherical equivalent refractive error (SER). One hundred ninety-six participants aged 3 to <11 treated with overminus lenses for 12 months were analyzed to explore associations between age, sex, race, ethnicity, strabismus severity, accommodative convergence/accommodation ratio (AC/A), and baseline SER with outcomes of change in SER and change in control. Analyses included outcomes for both SER and control as continuous and binary outcomes, and a secondary combined outcome. More myopic baseline refractive error and older age were associated with a worsening in SER after 12 months, -0.08 diopters (D) worsening SER per 1 year age increase (95% CI -0.13 to -0.03), and -0.30 D worsening SER per additional 1 D of myopic refractive error (95% CI -0.39 to -0.21). A larger AC/A ratio was associated with better distance control (0.11 points improvement per D of AC/A, 95% CI 0.03 to 0.19). The combined SER and control outcome showed the same factors (age, baseline refractive error, and AC/A ratio) were significantly associated with improving outcomes. Overminus lens therapy may be beneficial for some patients, but further study is needed to explore the results of these exploratory analyses.

Socioecological Factors Influencing The Anticipated Medical Help-Seeking Time For Breast Cancer Among Women In Togo, A Sub-Saharan Country, Komi Blewussi Aheto

Walden Dissertations and Doctoral Studies

Breast cancer remains a leading cause of death in sub-Saharan Africa (SSA). The burden of the disease in the region is partly attributed to delayed health-seeking, resulting in advanced disease presentation, delayed diagnosis, poor outcomes, and low survival. This quantitative cross-sectional study was conducted to investigate the socioecological factors that influence the anticipated medical health-seeking time for women in SSA experiencing breast cancer symptoms. The socioecological model (SEM) theoretical framework guided this study. A questionnaire was used to collect data from randomly selected (N = 343) women aged 18 years and older with no personal or familial history of breast …

Estimating The Number Of Polygenic Diseases Among Six Mutually Exclusive Entities Of Non-Tumors And Cancer, C I Edvard Smith, Jan A Burger, Rula Zain

Faculty, Staff and Student Publications

In the era of precision medicine with increasing amounts of sequenced cancer and non-cancer genomes of different ancestries, we here enumerate the resulting polygenic disease entities. Based on the cell number status, we first identified six fundamental types of polygenic illnesses, five of which are non-cancerous. Like complex, non-tumor disorders, neoplasms normally carry alterations in multiple genes, including in 'Drivers' and 'Passengers'. However, tumors also lack certain genetic alterations/epigenetic changes, recently named 'Goners', which are toxic for the neoplasm and potentially constitute therapeutic targets. Drivers are considered essential for malignant transformation, whereas environmental influences vary considerably among both types of …
