Embolic Protection During Radical Nephrectomy With Inferior Vena Cava Thrombectomy Using The Protrieve Sheath, Mia Rose Schmolze

Research Symposium

Renal Cell Carcinoma (RCC) is complicated by inferior vena cava (IVC) involvement in 4-10% of cases with intraoperative tumor embolization associated with 60-75% mortality. Currently, there is no high-level evidence demonstrating which surgical techniques provide optimal outcomes. The Protrieve SheathTM (Inari Medical®) has been used in the vascular setting for complex deep vein thrombosis(DVT) and non-tumor IVC thrombectomy cases. We aim to describe its first use in the setting of RCC with IVC thrombectomy to help prevent intraoperative tumor embolization. The Protrieve SheathTM successfully provided potentially life-saving protection from clot embolization when performing radical nephrectomy with IVC thrombectomy.

Cucurbitacin B: A Novel Agent For Inducing Tumor-Immune Response., Sahir S. Alvi, Emmanuel Anning, Mudassier Ahmad, Carlos Perez, Mehdi Chaib, Subhash C. Chuahan, Taha Merghoub, Bilal B. Hafeez

Research Symposium

Despite the emergence of immunotherapy as a potential breakthrough in cancer treatment, it showed only a marginal response in pancreatic and liver cancers. Thus, novel strategies are highly desirable to take full advantage of immunotherapy in the treatment of these cancers. One of the critical factors that influence the efficacy of immunotherapy is the increased infiltration of myeloid-derived suppressor cells (MDSCs) and tumor-associated macrophages (TAM) into tumors that alter the immune landscape and serve as facilitators of tumor proliferation, metastatic growth, and immunotherapy resistance. Thus, we believe that selecting a potent molecule that has the ability to suppress the function …

A Novel Exo-Glow Nano-System For Bioimaging, Nycol Cotto, Benilde Adriano, Neeraj Chauhan, Deepak S. Chauhan, Meena Jaggi, Subhash C. Chauhan, Murali M. Yallapu

Research Symposium

Background: Milk exosomes are widely used to improve the performance of various small macromolecules, oligonucleotides, and imaging agents for delivery and imaging applications. Indocyanine green (ICG) based Near-Infrared (NIR) fluorescent imaging is an attractive and safer technique used for number of clinical applications. However, ICG tend to have poor photostability, short half-life, non-specific proteins binding, and concentration-dependent aggregation. Therefore, there is an unmet clinical need to develop newer modalities to package and deliver ICG. Bovine milk exosomes are natural, biocompatible, safe, and feasible nanocarriers that facilitate the delivery of micro and macro molecules. Herein, we developed a novel exosomes based …

Near-Neutral Balanced Selection Theory (Nnbst): Implication On The Molecular Evolution Of Sars-Cov-2 And Zika Virus, Nicholas J. Paradis

Graduate Student and Postdoctoral Fellow Symposium

Virus pandemics have significantly impacted human welfare and development. Understanding the true molecular evolution of viruses is critical for preventing future pandemics and developing the next-generation drugs and vaccines. Unfortunately, viruses exhibiting constant genomic substitution rates (GSRs) despite increasing vaccinations and human infections (SARS-CoV-2) and viruses under seemingly extreme conservation (ZIKV) paints a confusing picture of viral evolution, and the main evolutionary theories (Selectionist Theory, Kimura’s Neutral Theory) cannot explain their molecular evolution. Here, we developed a first-principle model, c/u, to characterize reproductive fitness changes in viruses based on variations in the nucleotide/codon mutation rate (c) with respect to the …

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 …

Repetitive Negative Thinking As A Prospective Predictor Of Depression And Anxiety Symptoms In Autistic And Non-Autistic Incoming College Students, Erin Kckenney

Graduate Student and Postdoctoral Fellow Symposium

Background: Improving the understanding and treatment of mental health concerns, including depression and anxiety, are significant priorities for autistic adults (Benevides et al., 2020; Crane et al., 2019; Pellicano et al., 2014). While several theories have been proposed to explain the high prevalence of internalizing symptoms in autistic people, little longitudinal research has been done to investigate potential causal mechanisms. One potentially fruitful area of investigation is to explore how well-known contributors to depression/anxiety in the general population predict and/or moderate the development of internalizing symptoms in autistic individuals. Objectives: The current study investigates the relation of one established risk …

Black Boys Om: A Case Study Of The Impacts Of Community And Culture On Wellness Practices, Khanh Pham

Graduate Student and Postdoctoral Fellow Symposium

Black men continue to face health disparities due to systemic oppression. Research indicates that mind-body-spirit practices (MBSPs) can effectively improve mental and physical health, thereby reducing health disparities among Black men. However, MBSPs are often White-female-dominated practices, thus putting Black male practitioners at continued risks of under-representation and marginalization in MBSP spaces. The culturally specific nature of MBSP spaces may then be an important factor in MBSPs’ influence on Black men’s health. Therefore, we aimed to explore how culturally specific MBSP spaces impact Black male practitioners’ MBSPs. We collaborated with Black Boys OM (BBO), a global community of Black male …

Examining Childhood Trauma And Substance Use Problems Among Justice-Involved Adolescents In Florida, Skye C. Bristol

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to assess the relationship between childhood trauma and substance use problems as latent constructs among justice-involved adolescents (JIA). Additionally, racial differences and spatial analyses were examined. Previous research underscores the limitations of conceptualizing childhood trauma solely through Adverse Childhood Experiences (ACEs). This justified integrating child welfare involvement, or out-of-home placement, as an additional indicator to develop a comprehensive scope of childhood trauma among JIA. Furthermore, current literature established that childhood trauma is a key predictor of substance misuse among JIA. However, the lack of a standardized measure of substance misuse across juvenile justice systems …

The Effect Of Virtual Standardized Patient Integrated Health Coach Training On Professional Confidence Gain In Veterans Health Administration Primary Care Nurses, David Mullins

Graduate Theses, Dissertations, and Capstones

Poor health behaviors cost the United States billions of dollars and tens of thousands of lives every year. The Veterans Affairs primary care delivery model uses health coaching as a catalyst to improve health behaviors in veterans. Health coaching is a complex skill that requires specialized training, repetitive practice, and professional confidence. Albert Bandura believed most people acquire skills and develop the confidence to use those skills through social learning. He posited that professional confidence played a critical role in skill acquisition, and people with low professional confidence were less likely to attempt to perform a skill. Bandura’s Theory of …

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 …

Amino Acid Formula Induces Microbiota Dysbiosis And Depressive-Like Behavior In Mice, Ji Hu, Kaixin He, Yifei Yang, Chuan Huang, Yiping Dou, Hao Wang, Guorong Zhang, Jingyuan Wang, Chaoshi Niu, Guoqiang Bi, Lan Zhang, Shu Zhu

Faculty, Staff and Student Publications

Amino acid formula (AAF) is increasingly consumed in infants with cow's milk protein allergy; however, the long-term influences on health are less described. In this study, we established a mouse model by subjecting neonatal mice to an amino acid diet (AAD) to mimic the feeding regimen of infants on AAF. Surprisingly, AAD-fed mice exhibited dysbiotic microbiota and increased neuronal activity in both the intestine and brain, as well as gastrointestinal peristalsis disorders and depressive-like behavior. Furthermore, fecal microbiota transplantation from AAD-fed mice or AAF-fed infants to recipient mice led to elevated neuronal activations and exacerbated depressive-like behaviors compared to that …

Previous studies have shown the clinical benefit of rechallenging the RAF pathway in melanoma patients previously treated with BRAF inhibitors. 44 patients with multiple tumors harboring RAF alterations were rechallenged with a second RAF inhibitor, either as monotherapy or in combination with other therapies, after prior therapy with a first RAF inhibitor. This retrospective observational study results showed that rechallenging with RAFi(s) led to an overall response rate of 18.1% [PR in thyroid (1 anaplastic; 3 papillary), 1 ovarian, 2 melanoma, 1 cholangiocarcinoma, and 1 anaplastic astrocytoma]. The clinical benefit rate was 54.5%; more than 30% of patients had durable …

A Novel Machine Learning Algorithm Selects Proteome Signature To Specifically Identify Cancer Exosomes, Bingrui Li, Fernanda G Kugeratski, Raghu Kalluri

Faculty, Staff and Student Publications

Non-invasive early cancer diagnosis remains challenging due to the low sensitivity and specificity of current diagnostic approaches. Exosomes are membrane-bound nanovesicles secreted by all cells that contain DNA, RNA, and proteins that are representative of the parent cells. This property, along with the abundance of exosomes in biological fluids makes them compelling candidates as biomarkers. However, a rapid and flexible exosome-based diagnostic method to distinguish human cancers across cancer types in diverse biological fluids is yet to be defined. Here, we describe a novel machine learning-based computational method to distinguish cancers using a panel of proteins associated with exosomes. Employing …

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 …
