Numerous studies have revealed the critical role of premature senescence induced by various cancer treatment modalities in the pathogenesis of aging-related diseases. Senescence-associated secretory phenotype (SASP) can be induced by telomere dysfunction. Telomeric DNA damage response induced by some cancer treatments can persist for months, possibly accounting for long-term sequelae of cancer treatments. Telomeric DNA damage-induced mitochondrial dysfunction and increased reactive oxygen species production are hallmarks of premature senescence. Recently, we reported that the nucleus-mitochondria positive feedback loop formed by p90 ribosomal S6 kinase (p90RSK) and phosphorylation of S496 on ERK5 (a unique member of the mitogen-activated protein kinase family …

Faculty, Staff and Student Publications

BACKGROUND: Current guidelines for patients with thoracic aortic aneurysms or dissections (TAD) restrict vigorous exertion with the intention to prevent acute aortic dissections. However, a safe threshold for exercise intensity has not been established for TAD patients. In this study, we measured exertional changes in systolic and diastolic blood pressure during isometric and dynamic exercises in a cohort of TAD patients to determine safety of moderate intensity exercise.

METHODS: Thirty-one adults with TAD and 14 controls were recruited from UTHealth outpatient clinics. All participants completed an exercise protocol consisting of two circuits of five moderate intensity exercises: hand grips, leg …

Severe Mixed Mitral Valve Disease Due To Massive Mitral Annular Calcification: A Case Report And Literature Review, Fateh Ali Tipoo Sultan, Sheema Saadia

Section of Cardiology

We present an unusual case of massive mitral annular calcification (MAC) leading to severe mixed mitral valve disease, viz severe mitral regurgitation and severe mitral stenosis. To our knowledge, severe mixed mitral valve disease secondary to MAC is extremely rare. The patient (a 65-year-old lady) presented with worsening shortness of breath and signs of congestive heart failure. Echocardiographic examination revealed massive mitral annular calcification. Despite the massive annular calcification, she had experienced neither embolism nor endocarditis in the past. Because of severe symptomatic mitral regurgitation and mitral stenosis, surgery was advised; however, the patient declined it.

Development Studies Faculty Publications

Lived experiences of chronic conditions are marked by fluidity and change, which should be considered if care is to be truly patient-centered. Seeking to capture this fluidity, we used digital diaries via mobile phones to communicate with hypertensive patients in the Philippines over approximately 12 months. This paper draws on Strong Structuration Theory to conceptualize the complex array of factors shaping participants’ usage (and non-usage) of the diaries, thereby offering a comprehensive understanding of how the diaries were perceived and used. We draw on qualitative data from 42 participants (73 baseline/follow-up interviews and 37 digital diaries), purposively selected from a …

Faculty, Staff and Student Publications

INTRODUCTION: Aging is associated with cardiac myocyte loss, sarcopenia, and cardiac dysfunction. Adult cardiac myocytes are postmitotic cells with an insufficient proliferative capacity to compensate for myocyte loss. The canonical WNT (cWNT) pathway is involved in the regulation of cell cycle reentry in various cell types. The effects of the cWNT pathway on the expression of genes involved in cell cycle reentry in the postmitotic cardiac myocytes are unknown.

AIM: The aim of the study was to identify genes whose expression is regulated by the β-catenin, the indispensable component to the cWNT signaling, in the postmitotic myocytes.

METHODS AND RESULTS: …

Self-Measured Blood Pressure Monitoring: A Patient Empowerment Project, Alison Cusmano

Doctor of Nursing Practice Final Manuscripts

Hypertension is a public health issue estimated to affect 112 million adults by 2030. Primary care patients in an outpatient clinic in Southern California with elevated blood pressure readings in the office did not have an organized system for close follow-up. The purpose of this evidence-based project (EBP) was to educate patients on self-measured blood pressure monitoring (SMBP), Dietary Approaches to Stop Hypertension (DASH), diet interventions, and healthy weight loss to improve hypertension rates. Through these interventions, patients developed an understanding of their systolic and diastolic blood pressure goals. Nurse practitioners, medical assistants, and licensed vocational nurses screened for high …

The Role Of Pre-Participation Exams In Identifying Student Athletes At Risk For Sudden Cardiac Arrest, Elizabeth Frey

Honors Projects

Sudden cardiac arrest (SCA) is the leading cause of death in young student athletes (Drezner et al., 2007). With athletes being recognized as some of the healthiest members of society, a catastrophic event like this can stimulate debate over pre-participation screening and appropriate emergency actions. With 55-80% cases of sudden cardiac death (SCD) being asymptomatic before the event (Drezner et al., 2007), looking into how well pre-participation screenings identify at risk individuals becomes much more important. This project investigates to what extent pre-participation physicals (PPE) can be improved to better identify student athletes at risk for sudden cardiac death and …

The Physiological Benefits Of A Plant-Based Diet On Cardiovascular Health, Jenevieve Petray

Nursing | Senior Theses

Cardiovascular disease (CVD) is increasingly more prevalent in today’s society and is attributed to an alarming percentage of American hospitalizations and deaths. Americans are unhealthier than ever before, and the main contributor is the Western diet. Diet is a double-edged sword that can offer benefits or detriments to one’s health. CVD encompasses numerous diagnoses originating from various underlying physiological alterations. These alterations are downstream effects of increased body weight and BMI, increased cholesterol levels, decreased insulin sensitivity and increased arterial plaque buildup. Research shows that a plant-based diet has the potential to manage and reverse all fundamental physiological alterations that …

Same Evidence, Varying Viewpoints: Three Questions Illustrating Important Differences Between United States And European Cholesterol Guideline Recommendations, David I. Feldman, Erin D. Michos, Neil J. Stone, Ty J. Gluckman, Miguel Cainzos-Achirica, Salim S. Virani, Roger S. Blumenthal

Office of the Provost

In 2018, the AHA/ACC Multisociety Guideline on the Management of Blood Cholesterol was released. Less than one year later, the 2019 ESC/EAS Dyslipidemia Guideline was published. While both provide important recommendations for managing atherosclerotic cardiovascular disease (ASCVD) risk through lipid management, differences exist. Prior to the publication of both guidelines, important randomized clinical trial data emerged on non-statin lipid lowering therapy and ASCVD risk reduction. To illustrate important differences in guideline recommendations, we use this data to help answer three key questions: 1) Are ASCVD event rates similar in high-risk primary and stable secondary prevention? 2) Does imaging evidence of …

Endovascular Treatment Of Acquired Atheromatous Postsubclavian Aortic Coarctation, Bhushan S Sonawane, Sreeja Pavithran, Kothandam Sivakumar

The Texas Heart Institute Journal

Coral reef aorta is a rare calcifying obstructive disease that involves the thoracoabdominal aorta. Similar presentations in the postsubclavian aorta may result in acquired atheromatous aortic coarctation leading to systemic hypertension and heart failure. The associated calcification makes surgical anatomic or extraanatomic bypass and thromboendarterectomy challenging. Extensive circumferential calcification often precludes endovascular intervention. We present the case of a 25-year-old man with an acquired atheromatous coarctation of the postsubclavian aorta who underwent successful endovascular treatment with use of a balloon-expandable covered stent.
