[Summary] Cardiomyocytes endure physical stress from the myocardium environment while generating their own mechanical strains. The force generated by sarcomeres is transmitted both longitudinally to adjacent sarcomeres and laterally to the cytoskeleton via intermediate filaments. This mechanical stimulus impacts other organelles, including the nucleus, thus playing a vital role in sensing and signaling nuclear adaptations. However, there is limited understanding of how changes in cardiac contractility affect nuclear mechanics. Here, we sought to investigate the effects of hyper- and hypo-contractility in nuclei of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) bearing TNNT2 pathogenic variants associated with hypertrophic (HCM) or dilated …


Physical Activity And Hypertension Outcomes Around Menopause In Adult Women—A Secondary Analysis Of The All Of Us Research Program, Meriam F. Naguib 2025 University of Central Florida

Physical Activity And Hypertension Outcomes Around Menopause In Adult Women—A Secondary Analysis Of The All Of Us Research Program, Meriam F. Naguib

Honors Undergraduate Theses

Hypertension significantly impacts menopausal women due to a decrease in estrogen levels. That is due to estrogen level changes, causing many metabolic alterations, one of which is increased vascular resistance, leading to hypertension. Advanced treatments are made available to help alleviate the condition; however, lifestyle modifications—especially physical activity—show a critical role in hypertension control. This thesis explored the effect of physical activity as a non-pharmacological, lifestyle intervention on hypertension in women by menopausal status (pre-, peri-, and post-menopausal). This study used a secondary analysis with a retrospective design. Physical activity was defined using the American Heart Association's (AHA) guidelines (i.e., …

Department Dermatology Faculty Publications

Background: Psoriasis is an independent risk factor for major adverse cardiovascular events (MACE). We have previously shown that psoriasis patients with dyslipidemia have an increased incidence of MACE despite treatment with a biologic and a statin. Glucagon-like peptide-1 receptor agonists (GLP-1RA) have shown to reduce MACE in patients with type 2 diabetes and obesity, comorbidities that commonly co-occur with psoriasis. However, the association between GLP-1RA and the incidence of MACE among patients with psoriasis remains unknown.

Methods: We conducted a retrospective cohort study from 2014-2024 using a large, multi-center, electronic health record network (TriNetX). Patients aged 18-90 who started GLP-1RA …

EVMS School of Health Professions Faculty Publications

Heart failure (HF) affects 6 million people in the US, and type 2 diabetes (T2D) is a significant risk factor for HF. Since 2008, regulatory agencies have required cardiovascular safety trials for new T2D therapies, and these have consistently demonstrated the cardiovascular benefits of glucose-lowering drugs. Sodium-glucose cotransporter inhibitors (SGLTi) and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs)/glucose-dependent insulinotropic polypeptide (GIP) reduce major adverse cardiovascular events and deaths, regardless of diabetes status, and improve cardiorespiratory fitness. SGLTis, such as dapagliflozin and empagliflozin, benefit patients with reduced and preserved ejection fraction, significantly reducing HF hospitalizations and cardiovascular deaths. The DAPA-HF and EMPEROR-Reduced …

Department of Medicine Faculty Publications

We report a case of Klinefelter syndrome (KS) diagnosed in adulthood, emphasizing the impact of phenotypic variability and the declining reliance on physical examination in delayed recognition. A 27-year-old male with obesity, low libido, and biochemical and clinical primary hypogonadism was found to have 47, XXY karyotype, consistent with KS. His hypogonadism was initially attributed to obesity and overlooked, despite classic signs of a micropenis and small testes. The case highlights the importance of physical examination, comprehensive history, and clinician awareness in diagnosing KS, particularly in atypical presentations. KS is associated with increased risks of osteoporosis, cardiovascular disease, and psychosocial …

Role Of Device Therapy In Complementing Contemporary Medical Management, Yoel Benarroch, Natalie Tapaskar, Amin Yehya

Department of Medicine Faculty Publications

Heart failure (HF) is a clinical syndrome characterized by signs and symptoms resulting from any structural or functional deficiency of ventricular filling or blood ejection. The mainstay of initial treatment remains lifestyle modifications, guideline-directed medical therapy, and addressing contributing factors. However, the past two decades have come with significant advances in device therapies to improve morbidity and mortality in HF despite evidence-based management as above. Given the rapidly evolving area of HF research and therapeutic development, it is important for clinicians to be familiar with novel therapies and how they can complement medical management. In this review we discuss the …

Percutaneous Closure Of A Left Ventricular Pseudoaneurysm Using A Post-Infarct Vsd Device Guided By Intracardiac Echocardiography, Omar Jafar, Nicholas Valle, Rupinder Bahniwal, Matthew Summers

Department of Medicine Faculty Publications

Left ventricular pseudoaneurysm (LVPA) is a rare, life-threatening complication that may arise after cardiac surgery, myocardial infarctions, or infective endocarditis. We present a case of a 55-year-old woman with complex surgical history and prior infective endocarditis who developed an incidental LVPA. Due to lack of surgical repair options, a percutaneous approach was pursued using a post-infarct ventricular septal defect device (PIVSD) under guidance of fluoroscopy and intracardiac echocardiography (ICE) guidance with successful exclusion of LVPA. This case highlights the utility of multimodal imaging in the percutaneous management of complex left ventricular lesions.

Psychophysiological Tools & Techniques To Predict Perceptual Motor Task Outcomes, Bobby Gerald Rawls III 2025 West Virginia University

Psychophysiological Tools & Techniques To Predict Perceptual Motor Task Outcomes, Bobby Gerald Rawls Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

The process of perceiving environmental information, analyzing it, formulating a plan of action, and carrying out said plan is vital to our day to day lives. This loop occurs for every motor task we perform, from actions as simple as elbow flexion to as complex as performing surgery. As such, it is imperative to understand what physiological, psychological, and neurocognitive factors most dictate success or failure in the motor performance loop.

Prior research has shown that measures from each of these facets have strong relationships with motor performance outcomes, though these findings tended to rely on artificially produced stress in …

Epicardial Cryoablation During Cardiopulmonary Bypass In A Pig Survival Model, Federica Serra, Jonathan M. Philpott, Anna Bulysheva, Christian W. Zemlin

Electrical & Computer Engineering Faculty Publications

Objective

Atrial cryolesions are usually created from the endocardium with the heart arrested. Some cardiac surgeons have used cryoablation epicardially during cardiopulmonary bypass, which is convenient because it does not require an incision into the atrial wall. Here, we analyzed the transmurality of epicardial cryoablations created during cardiopulmonary bypass in an arrested heart 30 days after ablation.

Methods

In Yucatan minipigs (n=5), hearts were exposed via sternotomy. Both caval veins were cannulated to collect blood for the cardiopulmonary bypass. Cryolesions were created applying a cryoprobe for 4 minutes per lesion. Hearts were harvested 30 days after the surgery. The transmurality …


Cardiac Timing Effects On Response Speed Are Modulated By Blood Pressure But Not Heart Rate Variability In Healthy Young Adults, Xiao Yang, Catalina Roldan, Michael Gazzanigo, Yasmine Nabulsi, Fang Fang 2025 Old Dominion University

Cardiac Timing Effects On Response Speed Are Modulated By Blood Pressure But Not Heart Rate Variability In Healthy Young Adults, Xiao Yang, Catalina Roldan, Michael Gazzanigo, Yasmine Nabulsi, Fang Fang

Research and Infrastructure Service Enterprise (RISE) Faculty Publications

Cardiac timing effects reflect the dynamic interplay between interoceptive and exteroceptive processes. Human information processing tends to be facilitated during cardiac diastole and inhibited during systole, reflecting autonomic regulation and the neuromodulation by baroreceptor afferents. Thus, blood pressure (BP) and vagally-mediated heart rate variability (vmHRV) are potential modulators of those effects. Additionally, cognitive control appears to play a critical role in the processes. However, whether cardiac timing effects are influenced by those factors remains unclear. The present study aimed to clarify these relationships. Fifty-one healthy young adults completed three experimental sessions to assess BP, short-term HRV, and cardiac timing effects. …
