Off-Label Clinical Applications Of Lefamulin For Multidrug-Resistant Tuberculosis And Sexually Transmitted Infections, Kerel Morris, Sukaina Momin, Vicky Mody, Shashidharamurthy Taval

Research Day

Lefamulin is a newer pleuromutilin antibiotic approved by the FDA (2019) for the treatment of community-acquired bacterial pneumonia (CAP). In addition, recent studies have shown the off-label use of Lefamulin to treat multidrug-resistant tuberculosis (MDR-TB) and sexually transmitted infections (STIs) caused by Mycoplasma genitalium. Therefore, this study aimed to conduct a literature review evaluating the potential off-label applications of lefamulin. Treatment of MDR-TB is typically complex because of the increased resistance to the standard first-line therapy. In addition, the entry of antibiotics into macrophages is limited by hypoxia, granulomas, and necrosis caused by MDR-TB. Studies have shown that Lefamulin exhibits …

Understanding Doxycycline-Induced Phototoxicity, Setareh Khani, Sydnee Jackson, Darya Khani, Rekha Yesudas

Research Day

Introduction: Doxycycline is a tetracycline-class antibiotic that inhibits bacterial protein synthesis by binding to the 30s ribosomal subunit, thereby preventing bacterial growth. It has a broad spectrum of clinical indications including treatment of Chlamydia infections, Lyme disease, Anthrax, Rickettsia, Atypical pneumonia, Staph aureus, Cholera, Acne vulgaris, and Traveler’s diarrhea, as well as malarial prophylaxis. Although generally well tolerated, effective and affordable, doxycycline is associated with several mild adverse effects like gastrointestinal distress and photosensitivity. One clinically significant adverse reaction is phototoxicity which occurs following exposure to ultraviolet radiation. In doxycycline-induced phototoxicity, the drug absorbs UV light and generates reactive oxygen …

Targeting Dysbiosis: Rebyota As A Novel Strategy For Recurrent Cdi Prevention, Christina Cologer, Mishel Alvarez, Sia Christine, Brooklyn Myers, Kaytlin Pal, Katrina Strand, Vicky Mody, Shashidharamurthy Taval

Research Day

Clostridioides difficile is a bacterium that colonizes a patient's gastrointestinal tract after the use of systemic antibiotics. This infection, also called CDI, causes severe diarrhea and can be life-threatening. In some patients, CDI recurs, creating a dangerous cycle. Recurrent CDI (rCDI) persists because systemic antibiotics induce dysbiosis, disrupting the gut microbiota’s metabolic functions and compromising the intestinal epithelial barrier. This study was conducted as a literature review evaluating the safety, efficacy, mechanism of action, and clinical use of Rebyota in preventing rCDI. Rebyota is the first FDA-approved (2023) live biotherapeutic designed to restore eubiosis in adult patients after antibiotic treatment. …

Zoonotic Streptococcus Equi Subspecies Epidemicus Bacteremia With Prosthetic Joint Injection And Dvt In An Elderly Patient: A Case Report And Literature Review, Bhavik Singh, Zoë M. Rushetsky, Zoheb I. Sulaiman, Eileen M. Raynor

Research Day

Introduction

Streptococcus equi subspecies zooepidemicus (SEZ) is a beta-hemolytic group C streptococcus commonly found in the upper respiratory tract of horses and other animals. Although SEZ is a frequent cause of equine “strangles,” human infection is exceptionally rare and associated with direct animal contact or consumption of unpasteurized animal products. Human SEZ infections have been reported to present with bacteremia, septic arthritis, endocarditis, or meningitis—particularly in immunocompromised individuals—but involvement of prosthetic joints is scarcely described in the literature. This case highlights an unusual zoonotic presentation of SEZ bacteremia in an elderly male with frequent equine exposure that was complicated by …

Breaking The Cycle: Uromune Mv140 In The Prevention Of Recurrent Urinary Tract Infections (Rutis), Katrina Strand, Sia Christine, Brooklyn Myers, Kaytlin Pal, Mishel Alvarez, Christina Cologer, Vicky Mody, Shashidharamurthy Taval

Research Day

Women who experience recurrent urinary tract infections (rUTIs), defined as more than three infections per year, often face significant reduction in their quality of life, including travel and employment. Additionally, there is concern about the long-term effects of prolonged and repeated use of antibiotics, which are currently the standard for prophylaxis and treatment. Overuse often results in resistance. Multiple countries currently offer, or are in the process of developing, vaccines that can prevent rUTI. Uromune MV140 from Immunotek is one such vaccine. This study was conducted as a literature review evaluating the safety, efficacy, mechanism of action, and clinical use …

Exploration Of A Relationship Between The Activities Of Trail And 4’-Trifluoromethoxychalcone., Abigail C. Ernst

Undergraduate Theses

Cancer is the overgrowth of dysregulated or mutated cells that affects 1 in 3 Americans. Chalcones are natural products with many possible derivatives, such as 4’-trifluromethoxychalcone (4TF), developed in Dr. Krzysiak’s lab, which exhibit anticancer activity against cancer cell lines. Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (TRAIL) is a tumor surveillance cytokine that acts on two receptor types: death receptors and decoy receptors. One way cancer cells can become resistant to TRAIL is by upregulating decoy receptors and/or downregulating death receptors. In this study, MTS assays evaluated the potential relationship between TRAIL and 4TF that sensitizes A549 cells to TRAIL. The …

The Fungus Among Us: Latency, Reactivation, And The Expanding Clinical Spectrum Of Coccidioidomycosis, Sumeet Bhardwaj, Arushi Tewari, Rishima Tewari, Simona Kogan

Student Publications

Coccidioidomycosis is a serious fungal infection that can produce a wide range of clinical manifestations, from mild, self-limiting pulmonary disease to severe, disseminated infection that can involve nearly any organ system, including the skin. Coccidioidomycosis may also affect patients at the psychiatric level. Its clinical relevance has increased markedly in recent years, as incidence continues to climb, geographic distribution widens, and emerging presentations challenge traditional assumptions regarding fungal latency and host immunity. A notably important and developing area of study is the concept of late reactivation. A narrative review of the literature was conducted using PubMed, MEDLINE, and Google Scholar. …

The Social Determinants Of Health And Cancer, Joshua Williams

Ex Sapientia Loqui

The social determinants of health, as defined by the World Health Organization (WHO), are “the conditions in which people are born, grow, live, work and age, and people’s access to power, money and resources.” Epidemiologists have long studied the nexus between social forces and disease and have widely agreed that such forces are directly causal of pathologies. This paper is an analytic review of the existing literature on several social determinants— namely socioeconomic status (SES), race and ethnicity, age, working and living conditions, and social integration— and how they pertain to the causation, progression, and treatment of cancer.

Product Of Arachidonic Acid Oxidation Inhibits Neutrophil Migration By Forming The Inflammatory Substrate For Integrin Αmβ2, Jared Casteel

Dr. Jay W. Boland Research Day

Oxidation of arachidonic acid generates biologically active derivatives that play a critical role in shaping the inflammatory response. One such derivative, carboxypropylpyrrole (CPP), is a stable end-product of arachidonic acid oxidation that has been previously described and detected in inflamed tissues; however, its pathophysiological contribution to inflammation has not been investigated. CPP forms covalent adducts with the extracellular matrix and plasma proteins, altering their biochemical properties and receptor-binding characteristics. Here, we examined how CPP formation impacts neutrophil migration during acute inflammation. Using cell adhesion assays and biolayer interferometry, we identified integrins αMβ2 and αDβ2 as receptors for CPP-modified proteins. Among …

Appalachian Therapies, Emma Marie Wilson

Dr. Jay W. Boland Research Day

It is predicted that by 2050, deaths due to antibiotic resistance will supersede cancer and cardiovascular disease as the number one cause of death in the world. The present research aims to study the polymicrobial interactions of microbial communities in the Appalachian region. Microbial samples were obtained from mountains surrounding East Tennessee State University, isolated and screened against common human opportunistic bacteria. One particular bacterium, S1S4-10, was found to be antagonistic against Bacillus subtilis and created zones-of-inhibition on agar media. Reverse testing found that the B. subtilis did not have a counter inhibition against S1S4-10. Co-cultures found that S2S4-10 could …

Modeling Bitcoin Dynamics Using Differential Equations, Boone M. Fleenor

Departmental Honors & Graduate Capstone Projects

In this thesis, we develop and analyze two nonlinear systems of ordinary differential equations to model Bitcoin price dynamics. Analytical techniques are used to obtain exact or approximate solutions where possible. Then, numerical simulations using a fourth-order Runge–Kutta method are employed to explore system behavior beyond analytically tractable regimes. Finally, model outputs are compared to historical Bitcoin price data using normalized and resampled time series. These results suggest that deterministic models can provide meaningful insight into the structural behavior of Bitcoin markets, while highlighting the need for stochastic or time-dependent extensions for more realistic modeling.

Background/aim: Osteoporosis is a multifactorial skeletal disease that predominantly affects postmenopausal women and is characterized by reduced bone mass and an increased risk of fractures. Growing evidence suggests that the gut microbiota plays a pivotal role in bone metabolism through immunological, endocrine, and metabolic pathways, forming the basis of the so-called gut– bone axis. This study aimed to characterize gut microbiota composition in postmenopausal women with osteoporosis compared with healthy controls.

Materials and methods: Forty postmenopausal women aged 55–65 years were classified into osteoporosis (n = 20) and healthy control (n = 20) groups based on dual-energy X-ray absorptiometry T-scores. …

The Deregulation Of Cancer, Daniel G. Aaron

Texas A&M Law Review

Fifty years ago, the U.S. embarked on a radical new path. Under pressure from the environmental movement, Congress passed an array of statutes aimed at regulating carcinogens out of our world. This regulatory experiment sprawled from air and water to food and consumer products.

Legal scholars have paid scant attention to this wave of cancer regulation despite its size and importance and the public’s apparent interest in avoiding carcinogens. But there is a growing literature finding flaws with individual regimes within the framework, such as the Clean Air Act, the Toxic Substances Control Act, and the Tobacco Control Act. In …

2020-Current year OA Pubs

Ready-to-use therapeutic and supplementary foods (RUTF/RUSF) are a primary treatment for childhood malnutrition in Community Management of Acute Malnutrition (CMAM) programs. However, measuring intervention compliance is labor intensive and unreliable. We applied FoodSeq, a fecal genomic dietary assessment biomarker, in malnourished infants (3-15 months) from Matiari, Pakistan. FoodSeq identified a significant increase in the abundance of DNA from chickpea, a primary RUSF ingredient, during RUSF administration and captured region-specific complementary feeding practices, including age-inappropriate feeding practices such as wide-spread tea consumption. Our findings highlight the potential of dietary genomics as an empirical and scalable tool for compliance monitoring and dietary …
