The Role Of A Cancer Testis-Antigen In Regulating Tumor Growth And Oncogenic Pathways In Triple-Negative Breast Cancer., Melina J. Sedano, Alana L. Harrison, Victoria Reid, Subramanian Dhandayuthapani, Shrikanth S. Gadad

Research Symposium

Breast cancer is the second leading cause of cancer-related deaths in women, after lung cancer. Unfortunately, it is the primary cause of death among Hispanic women. Approximately 10-20% of breast cancers are classified as basal (triple-negative) subtypes, which are challenging to treat due to the absence of specific targets. Triple-negative breast cancer is a highly aggressive and lethal type of tumor, particularly among Hispanic women, with a poor prognosis compared to other breast cancer subtypes. Therefore, it is crucial to identify new molecules with therapeutic and prognostic values to treat this evolving disease. Multiple studies have demonstrated that X-linked genes …

Fibrinolytic-Deficiencies Predispose Hosts To Septicemia From A Catheter-Associated Uti, Jonathan J Molina, Wei Xu, Karla Bergeron, Aleksandra Klim, Michael G Caparon, Scott J Hultgren, Alana Desai, Et Al.

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs) are amongst the most common nosocomial infections worldwide and are difficult to treat partly due to development of multidrug-resistance from CAUTI-related pathogens. Importantly, CAUTI often leads to secondary bloodstream infections and death. A major challenge is to predict when patients will develop CAUTIs and which populations are at-risk for bloodstream infections. Catheter-induced inflammation promotes fibrinogen (Fg) and fibrin accumulation in the bladder which are exploited as a biofilm formation platform by CAUTI pathogens. Using our established mouse model of CAUTI, here we identified that host populations exhibiting either genetic or acquired fibrinolytic-deficiencies, inducing fibrin deposition …

Existence Of A Nonzero Worst-Case Ach For Short-Term Exposure In Ventilated Indoor Spaces, K. A. Krishnaprasad, ‪Nadim Zgheib, K. Choudhary, M. Y. Ha, C. Y. Choi, K. S. Bang, S. Jang, S. Balachandar

Mechanical Engineering Faculty Publications

A well-ventilated room is essential to reduce the risk of airborne transmission. As such, the scientific community sets minimum limits on ventilation with the idea that increased ventilation reduces pathogen concentration and thus reduces the risk of transmission. In contrast, the upper limit on ventilation is usually determined by human comfort and the need to reduce energy consumption. While average pathogen concentration decreases with increased ventilation, local concentration depends on multiple factors and may not follow the same trend, especially within short exposure times over large separation distances. Here, we show through experiments and high-fidelity simulations the existence of a …

The Imitation Game: Drug Reaction Presenting As Autoimmunity Presenting As Syphilis, Victoria W. Murray, Liam Courtney, Judith Lightfoot

Graduate Student and Postdoctoral Fellow Symposium

Introduction: Syphilis screening, a common medical test in the US, is recommended annually in sexually active women younger than 25, annually for women older than 25, and annually for men(1). Standard tests include rapid reagin tests and Venereal Disease Research Laboratory tests, which react to membrane antigens of Treponema pallidum(2). Case reports of patients with autoimmune conditions have been described (3) but rarely considered in clinical practice. Additionally, patients may be underdiagnosed with autoimmune conditions with clinically relevant antibodies (4). Here, we describe one such case where a patient received delay in care prior to referral to our service. Case …

Ebola Distribution Prediction In Africa

Defensive Publications Series

Ebola Virus Disease (EVD) is a deadly illness with a fatality rate around 50%, which can spike to 90% during outbreaks. First identified in 1976 near the Ebola River in the Democratic Republic of Congo, EVD has caused sporadic but devastating outbreaks. The recent epidemic in West Africa is the most significant yet, affecting Guinea, Sierra Leone, and Liberia the most due to their weak healthcare systems. This situation has highlighted the need for better global health security and international cooperation to manage such diseases. Our paper focuses on these three countries to analyze the outbreak and response strategies, aiming …

Hesitation Towards The Covid-19 Vaccine In The United States: A Digital Ethnographic Study [Vacilación Ante La Vacuna Contra El Covid-19 En Estados Unidos De América: Un Estudio Etnográfico Digital], Rosalynn A. Vega

Anthropology Faculty Publications

Following the authorization of the use of COVID-19 vaccines in babies age 6 months through children 4 years old in the United States, some individuals (parents, pediatricians, and communicators) framed COVID-19 vac-cination as an issue of access, while many others expressed hesitancy, and some resisted recommendations from the US Centers for Disease Control and Prevention. In this context, this study aimed to explore: 1) divergent reactions to the authorization of COVID-19 vaccine use in children aged 6 months to 4 years; and 2) opposing logics underlying attitudes towards pro-vaccination, anti-vaccination, and vaccine hesitancy regarding COVID-19 vaccines. To achieve this, a …

Exploring The Associations Between Drug Resistant Mutations, Low-Level Viremia, And Virological Failure In Persons With Hiv In Florida, Adriana Campos

USF Tampa Graduate Theses and Dissertations

Virologic suppression is an essential part to a successful regimen for Persons with HIV (PWH) and the 95-95-95 initiative. Yet, PWH experiencing episodes of low-level viremia (LLV) may be more prone to experience virological failure (VF). Currently, studies debate the clinical relevance of LLV and its effect on virological outcomes, but none have explored its interconnectedness with drug resistant mutations (DRM) and antiretroviral treatment (ART) adherence – all integral elements in predicting virological outcomes.

The goal of the proposed study was to contribute to the knowledge gap regarding the interconnectivity of drug resistant mutations, low-level viremia, adherence, and virological failure …

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe

USF Tampa Graduate Theses and Dissertations

Background: Community based surveillance (CBS) is the organized and rapid collection of information from health events identified in the community and includes the systematic detection and reporting of events of public health significance. While used globally to enhance the detection of priority diseases, CBS has not been routinely deployed in Iraq, where a once-robust health system has been devastated by decades of war, international sanctions, and large-scale population displacement. During infectious disease outbreaks, it is imperative to quickly detect and isolate suspect cases, investigate confirmed cases, and trace and monitor the contacts of confirmed cases. The COVID-19 pandemic underscored the …

Efficacy And Feasibility Of Short-Stretch Compression Therapy For Filarial Lymphedema In Sri Lanka, Jaimee M Hall, Nirmitha Lalindi De Silva, Janaka Ruben, Sandani S Thilakarathne, Thishan Channa Yahathugoda, Philip J Budge

2020-Current year OA Pubs

The WHO-recommended essential package of care (EPC) for filarial limb lymphedema consists of daily limb washing, entry lesion management, limb protection, exercises, and elevation. Decongestive therapy (DT) with compression bandaging by trained lymphedema therapists adds additional benefit but is unavailable for most in low- and middle-income countries (LMICs). To determine whether DT using self-adjustable, short-stretch compression garments (SSCG), prefitted using portable, three-dimensional infrared imaging (3DII), would be effective and feasible in LMIC settings, we conducted a pilot 6-week, interventional, single-group, open-label pilot study in Galle, Sri Lanka. Ten participants with Dreyer stage 3 lymphedema used SSCG for 2 weeks after …

Methionyl-Trna Synthetase Synthetic And Proofreading Activities Are Determinants Of Antibiotic Persistence, Whitney N. Wood, Miguel Angel Rubio, Lorenzo Eugenio Leiva, Gregory J. Phillips, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial antibiotic persistence is a phenomenon where bacteria are exposed to an antibiotic and the majority of the population dies while a small subset enters a low metabolic, persistent, state and are able to survive. Once the antibiotic is removed the persistent population can resuscitate and continue growing. Several different molecular mechanisms and pathways have been implicated in this phenomenon. A common mechanism that may underly bacterial antibiotic persistence is perturbations in protein synthesis. To investigate this mechanism, we characterized four distinct metG mutants for their ability to increase antibiotic persistence. Two metG mutants encode changes near the catalytic site …

Financing Reforms To Meet A Pivotal Moment In Global Health, Kevin A. Klock, Alexandra Finch, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

2024 will be the most important moment for global health since the World Health Organization’s founding in 1948, but only if states give major reforms their full political and financial backing. Bold new commitments in disease surveillance, capacity building, and more equitable access to health products cannot be achieved without ample and sustainable funding. In this essay, we discuss major reforms found in the emerging pandemic agreement and reformed International Health Regulations and then explore the significant challenges and opportunities for financing them.

Mothers With Disabilities As Health Navigators: Narratives Of Pregnancy, Postpartum Depression, And Parenting, Agnes Amoakwa

Theses and Dissertations

Scholars have focused on factors that affect pregnancy decisions, linking it to internal factors such as physical attachment and love towards children and feasibility of external factors, among others, while others have focused on experience with health professionals and accessibility of healthcare facilities and equipment during access to maternal care. While these studies are important, fewer focus has been placed on how women with disabilities navigate the postpartum phase of motherhood and the support needed to navigate through this experience. I employed the communicated narrative sense-making theory to explore the meanings of stories shared by mothers with disabilities about their …

The Invasive Bank Vole (Clethrionomys Glareolus); A Longitudinal Investigation Into Rodents And Their Pathogen Communities, Using The Irish Rodent Invasion As A Model System., Andrew Mcmanus

Theses

The recent emergence of zoonotic pathogens such as, SARS-CoV-2, Ebola and Mpox, have emphasised the necessity to study wildlife and their pathogens. A knowledge gap currently exists in longitudinal studies of biological invasions, which are needed to understand the change in pathogen communities caused as the invader becomes more established. The invasion of Clethrionomys glareolus in Ireland provides a unique model system to study these changes at different stages of the bio-invasion. This is due to the depauperate small mammal community in Ireland, identifiable source population, introduction point, and ongoing expansion of C. glareolus in Ireland. Extensive work has been …

Effectiveness Of Frog Skin Secretions Against Uv-B Radiation, Connor Mcgaha, Kinkade Mcmurray, Lee B. Kats

Seaver College Research And Scholarly Achievement Symposium

As an increasing number of their species face possible extinction, amphibian populations have been steadily declining over the past decades (IUCN). While various factors have been suggested or proven to be partially responsible for this reduction, increased ultraviolet B radiation (UVBR) appears to be one of the more prominent explanations, especially when considering the continual thinning of the Earth’s ozone layer due to anthropogenic climate change. However, it has also been discovered that skin secretions, which are reported to function as a component of amphibians’ innate immune systems, may have an effect on UVBR (Cramp and Franklin). With this in …
