Department of Medicine Faculty Publications

Background Retrograde valve crossing during valve-in-valve transcatheter aortic valve replacement (ViV TAVR) may fail despite modern delivery systems. Case Summary A 67-year-old man with a degenerated 27-mm Magna Ease bioprosthesis and unfavorable aortic geometry (kinked ascending aorta at a prior surgical graft site) underwent ViV TAVR, where retrograde valve crossing failed despite multiple stiff guidewires and snare traction alone. Successful delivery of a 29-mm Evolut FX+ was ultimately achieved by combining gooseneck-snare traction for coaxial realignment with a partially inflated Tyshak buddy balloon acting as a mechanical ramp across the surgical valve frame. Discussion This case demonstrates a structured, stepwise …

Percutaneous Closure Of Ventricular Septal Rupture After Myocardial Infarction:, Thomas A. Cook, Simone K. Schumaecker, Anjani Patibandla, Nicholas J. Valle, Matthew R. Summers

Department of Medicine Faculty Publications

BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction is a rare but deadly complication with mortality rates exceeding 90% when left untreated. Coronary ischaemia leads to myocardial necrosis and friability resulting in septal rupture, most commonly 3-5 days post-infarction. The sudden development of a left-to-right shunt causes volume overload in the right ventricle, pulmonary vasculature, and left atrium, precipitating biventricular failure, and cardiogenic shock. Management requires careful consideration of timing and modality of closure along with stabilization with mechanical circulatory support in severe cases.

CASE SUMMARY: A 65-year-old female presented with anterior ST-segment elevation myocardial infarction complicated by VSR …

Baseline Lymphopenia Predicts Survival In Ici-Naïve Solid Tumor Patients Receiving Immune Checkpoint Inhibitors: A Propensity-Matched Real-World Pan-Cancer Analysis, Ahmed Ismail, Nina Balanchivadze, George R. Simon, Yanis Boumber

Department of Medicine Faculty Publications

Background: Baseline lymphopenia is common among advanced solid tumors and may influence the efficacy/safety of immune checkpoint inhibitors (ICIs), but large real-world evidence is limited. We evaluated the association between baseline absolute lymphocyte count (ALC) and clinical outcomes in adults with solid tumors treated with ICIs in routine practice. Methods: We performed a retrospective cohort study using TriNetX. Adults with solid tumors who received pembrolizumab, nivolumab, or atezolizumab (ICI-Naïve) between January 2015 and June 2026 were included. Baseline ALC was measured within 30 days before first treatment and was classified as lymphopenic (ALC < 1.5 × 10⁹/L) or non-lymphopenic (ALC ≥ 1.5 × 10⁹/L). Propensity score matching (1:1) yielded 5249 patients per group. The index date was the first immunotherapy date, and outcomes were assessed at 6, 12, 24, 36 months, and 5 years. The primary outcome was 24-month overall survival (OS); secondary outcomes were OS at 6 and 12 months and 6-month risks of healthcare utilization, immune-related adverse events (irAEs), and serious infections; and exploratory outcomes included OS at 36 months and 5 years. All outcomes were analyzed using Kaplan–Meier analysis, Cox proportional hazards models, and risk ratios. Subgroup analysis included OS stratified by solid tumor subtypes and prior lines of therapy. Results: After matching, patients with baseline lymphopenia …

Department of Medicine Faculty Publications

Background and AIMS

Fully covered self-expandable metal stents (FcSEMSs) have become the mainstay of treatment for a variety of biliary pathologies. However, FcSEMSs have been associated with a greater rate of stent migration than other types of stents. A technique of anchoring double-pigtail plastic stents (DPPSs) has been proposed to minimize migration of biliary FcSEMSs. Herein, we evaluated the efficacy of anchoring DPPSs among patients treated with biliary FcSEMSs.

Methods

We performed a systematic review using PubMed, EMBASE, and Web of Science from database inception through August 2023. Full-text articles comparing FcSEMSs with or without anchoring DPPSs were included. We …

Department of Biomedical and Translational Sciences Faculty Publications

Circulating tumor cells (CTCs) face challenges to their survival, including mechanical and oxidative stresses that are different from cancer cells in solid primary and metastatic tumors. The impact of adaptations to the fluid microenvironment of the circulation on the outcome of the metastatic cascade is not well understood. Here, we find that cancer cells exposed to brief pulses of high-level fluid shear stress (FSS) exhibit enhanced invasiveness and anchorage-independent proliferation in vitro and enhanced metastatic colonization/tumor formation in vivo. Cancer cells exposed to FSS rapidly alter their metabolism in a manner that promotes survival by providing energy for cytoskeletal remodeling …

Localization And Functional Exploration Of Leiomodin-2'S C-Terminal Binding Sites, Mason D. Summers, Madison Little, Robert P. Young, Brayan Osegueda, Alan Palma Guillen, Garry E. Smith Jr., John R. Cart, Vitold E. Galkin, Alla S. Kostyukova

Department of Biomedical and Translational Sciences Faculty Publications

Striated muscle contraction occurs through interactions between overlapping myosin-based thick and actin-based thin filaments within the sarcomere. For effective contraction to occur, the length of the thin filament must be maintained to ensure sufficient overlap with the thick filament. The proteins leiomodin and tropomodulin compete for binding at the pointed ends of thin filaments to regulate their length, using their homologous N-terminal actin and tropomyosin binding sites. Leiomodin also contains a region called the C-terminal extension, absent in tropomodulin. In this region, the cardiac isoform (leiomodin-2) contains additional actin-binding sites that enable it to bind along the sides of thin …

Cervicovaginal Lavage Fluid Iron And Manganese Levels In Women With And Without Vaginitis, Barbara Kozma, David Ratonyi, Bence Kozma, Peter Takacs, Attila G. Sipos

Department of Obstetrics & Gynecology Faculty Publications

Transition metals such as iron and manganese are critical for cellular metabolism, redox balance, and immune function, and they also influence host–pathogen interactions. Vaginitis is characterized by mucosal inflammation that may alter local trace-element homeostasis. We hypothesize that inflammatory conditions such as vaginitis may be associated with altered cervicovaginal iron and manganese levels. We performed a prospective, single-center cohort study at the University of Debrecen (Hungary) between April 2023 and April 2024, enrolling 80 women ≥ 18 years with vulvovaginal complaints. Participants were assessed at baseline and at weeks 4, 8, and 12 with clinical evaluation and cervicovaginal lavage (CVL) …

The Myopia Epidemic: Integrating Genetic, Environmental, And Epigenetic Pathways To Define A Critical Window For Intervention, Pranavika Balaji

Undergraduate Research Posters

Myopia, or nearsightedness, has increased rapidly worldwide and is now a major public health concern caused by both genetic and environmental factors. Current understanding shows that too much near work, limited time spent outdoors, and prolonged screen use contribute to abnormal eye growth in individuals who may already have a genetic predisposition. At the molecular level, epigenetic changes and shifts in DNA activity, often influenced by environmental conditions, affect the signaling pathways that regulate eye development and may help explain why myopia is increasingly common among children. This paper synthesizes recent environmental, genetic, and epigenetic research to explain how these …

Nanosecond Pulsed Electric Fields For Extracellular Vesicle Engineering: From Electro-Exocytosis To Cargo Modulation, Art Neal, Teresa Graham, Mohamadmahdi Samandari, Arash Ghorbannia, Anca Dobrian, Stephen J. Beebe, Ruben M. L. Colunga-Biancatelli

Bioelectrics Publications

Extracellular vesicles (EVs), including small extracellular vesicles (sEVs) and medium/large extracellular vesicles (MVs), have emerged as promising therapeutic vectors and diagnostic biomarkers across various branches of biomedicine. However, the clinical translation of EV-based technologies remains constrained by persistent challenges in manufacturing: insufficient yield from primary cell sources, limited control over cargo composition, and the absence of scalable, standardized production platforms. Nanosecond pulsed electric fields (nsPEF) represent an emerging biophysical approach that can address several of these limitations. Unlike conventional electroporation, which targets the plasma membrane using microsecond-to-millisecond pulses, nsPEF delivers ultrashort (1–300 ns), high-amplitude (10–300 kV/cm) pulses that penetrate intracellularly …

Probiotic Intervention In Managing Chronic Stress, Bianca Opdenbosch

PANDION: The Osprey Journal of Research and Ideas

Chronic stress can induce gut dysbiosis which contributes to the dysregulation of the gut-brain axis and leads to anxiety and depressive-like symptoms. The gut-brain axis relies on nervous, immune, and endocrine interactions. Gut dysbiosis, an imbalance within the gut microbiome, disrupts gut-brain communication, impairing gut barrier integrity, inflammation regulation, and hormonal and neurotransmitter production. These gut changes contribute to mood disorders resulting from stress, and thus it is important to implement dietary interventions, like probiotics, to help mitigate these effects. Research highlights the potential of probiotics to act as an intervention to combat stress-induced gut dysbiosis and replenish beneficial bacteria …

Introducing Patient-Centered Outcomes To Preceptors In Caate-Approved Athletic Training Programs, K. Judge

Clinical Practice in Athletic Training

The 2020 standards set by the Commission on Accreditation of Athletic Training Education (CAATE) now require the incorporation of the International Classification of Function and Patient-Centered Outcomes into professional practice. These standards can be introduced initially through simulation, but to develop a competent and culturally aware professional, outcome measures should be completed during clinical experiences under the guidance of approved preceptors. As this is a relatively new standard, many preceptors did not receive this as part of their education and may be uncomfortable integrating outcomes into their practice. This lack of integration can negatively affect the learning opportunities of athletic …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …
