We have shown that membrane-associated guanylate kinase with inverted domain structure-1 (MAGI1), a scaffold protein with six PSD95/DiscLarge/ZO-1 (PDZ) domains, is involved in the regulation of endothelial cell (EC) activation and atherogenesis in mice. In addition to causing acute respiratory disease, influenza A virus (IAV) infection plays an important role in atherogenesis and triggers acute coronary syndromes and fatal myocardial infarction. Therefore, the aim of this study is to investigate the function and regulation of MAGI1 in IAV-induced EC activation. Whereas, EC infection by IAV increases MAGI1 expression, MAGI1 depletion suppresses IAV infection, suggesting that the induction of MAGI1 may …

Complexities And Complications Of Extreme Obesity, Haval Ali, Udit Naik, Michelle Mcdonald, Mohammad Almosa, Karen Horn, Alexis Staines, Louis Maximilian Buja

Faculty, Staff and Student Publications

Obesity is a common chronic disorder and has detrimental long-term consequences if left untreated. Herein, we report a case of a young lady who suffered from morbid obesity and many of its consequences, and we present a literature review of these complications. While the cause of obesity is multifactorial, the genetic component is particularly important in the pathophysiology of marked obesity. Resistance to Leptin is considered one of the main causes of obesity. There is a unique relationship between polycystic ovary syndrome and obesity, as observed in our case. Obesity is associated with cardiovascular and lung diseases such as heart …

The molecular and cellular processes leading to aortic aneurysm development in Marfan syndrome (MFS) remain poorly understood. In this study, we examined the changes of aortic cell populations and gene expression in MFS by performing single-cell RNA sequencing (scRNA seq) on ascending aortic aneurysm tissues from patients with MFS (n = 3) and age-matched non-aneurysmal control tissues from cardiac donors and recipients (n = 4). The expression of key molecules was confirmed by immunostaining. We detected diverse populations of smooth muscle cells (SMCs), fibroblasts, and endothelial cells (ECs) in the aortic wall. Aortic tissues from MFS showed alterations …

Journal of the Saudi Heart Association

Background: Assessment of the shape and dimensions of PDA is usually done angiographically and in the majority of cases need arterial access. Our aim was to evaluate the value of routine 2 D echocardiography (ECHO) in predicting type, dimensions of PDA and to anticipate device size to be used during the intervention. Material and Methods: The charts of all patients who underwent transcatheter closure of PDA between January 2015 and December 2020 were reviewed. Their pre-procedure ECHO and catheterization details at the time of device closure were analyzed. Results: Total of 139 patients were reviewed and 8 were excluded because …

Role Of Serum Amyloid A In Abdominal Aortic Aneurysm And Related Cardiovascular Diseases, Preetha Shridas, Avery C. Patrick, Lisa R. Tannock

Internal Medicine Faculty Publications

Epidemiological data positively correlate plasma serum amyloid A (SAA) levels with cardiovascular disease severity and mortality. Studies by several investigators have indicated a causal role for SAA in the development of atherosclerosis in animal models. Suppression of SAA attenuates the development of angiotensin II (AngII)-induced abdominal aortic aneurysm (AAA) formation in mice. Thus, SAA is not just a marker for cardiovascular disease (CVD) development, but it is a key player. However, to consider SAA as a therapeutic target for these diseases, the pathway leading to its involvement needs to be understood. This review provides a brief description of the pathobiological …

Improving Care For Patients With Atrial Fibrillation Through The Use Of A Personal Electrocardiogram, Teresa Praus, Jonathan Li, Svetlana Barbarash, Manuel Proenza, Mary D. Bondmass

Nursing Faculty Research

Background: Atrial fibrillation (AF) is the most common arrhythmia affecting more than six million people in the United States. The economic burden is estimated to be >$6 billion annually with catastrophic events dramatically increasing expenditure. When patients experience symptoms, they commonly present to an acute care facility; this can be costly and anxiety provoking. Local problem: Same-day access issues prohibit patients from communicating directly with their cardiology provider, forcing them to use resources and increasing psychological burden.Methods:A convenience sample, made up of 43 patients, was given a KardiaMobile device. Eligible patients had ≥2 AF-related emergency department (ED) or urgent care …

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 …

Thyroidectomy In Mechanical Circulatory Support - A Salvage Treatment For Thyrotoxicosis-Induced Cardiogenic Shock: Case Series, Rody G. Bou Chaaya, Lauren M. Saint, Onyedika J. Ilonze Md, Mph

The VAD Journal

Amiodarone is frequently used to treat arrhythmias in patients supported with left ventricular assist devices. Long term amiodarone use can cause hyperthyroidism ultimately leading to cardiomyopathy and sometimes thyrotoxicosis-induced cardiogenic shock (CS). We describe two cases of thyrotoxicosis-induced CS rescued by successful thyroidectomy under mechanical circulatory support (MCS) – one with a Heartmate III (Abbott Laboratories) and another supported with veno-arterial extracorporeal membrane oxygenation (V-A ECMO). In refractory CS, the initiation of V-A ECMO as a bridge to recovery is critical. In thyrotoxicosis-induced CS that is refractory to medical therapy requiring MCS, thyroidectomy is feasible, and a growing body of …

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 …

Derivation And Validation Of A General Predictive Model For Long Term Risks For Mortality And Invasive Cardiovascular Interventions In Congenital Heart Disease, David A. Danford

Capstone Experience: Master of Public Health

Introduction. Accurate assessment of prognosis is a key driver of clinical decision making in congenital heart disease (CHD), but is complicated because CHD represents such a diverse collection of conditions. The aim of this investigation is to derive, validate, and calibrate multivariable predictive models for time to surgical or catheter-mediated intervention (INT) in CHD and for time to death in CHD. Methods. 4108 unique subjects were prospectively and consecutively enrolled, and randomized to derivation and validation cohorts. Total follow up was 26,578 patient-years, with 102 deaths and 868 INTs. Accelerated failure time multivariable predictive models for the outcomes, based on …

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 …

The Role Of The Erbb Signaling Pathway In Cardiovascular Progenitor Cell-Based Repair, Christopher Ramos

Electronic Theses, Projects, and Dissertations

Adult mammalian hearts lack self-renewal and proliferative capabilities necessary for cardiovascular regeneration. Current treatments using cardiac progenitor cells (CPCs) for cell-based repair do not restore cardiac function in patients who experience a myocardial infarction (MI). Our laboratory has been studying Islet-1+ neonatal CPCs as a promising candidate for cell-based repair due to their ability to significantly improve cardiac function after MI in sheep. The current study addresses the hypothesis that the ERBB pathway is linked to the Hippo-pathway to activate YAP1 by the involvement of an autocrine loop that upregulates neuregulin (NRG). In our sheep model of MI and cardiovascular …

Heart and Vascular Articles

Background: Atherosclerosis is the primary cause of the cardiovascular disease (CVD). Several risk factors lead to atherosclerosis, and altered nutrition is one among those. Nutrition has been ignored quite often in the process of CVD risk assessment. Altered nutrition along with carotid ultrasound imaging-driven atherosclerotic plaque features can help in understanding and banishing the problems associated with the late diagnosis of CVD. Artificial intelligence (AI) is another promisingly adopted technology for CVD risk assessment and management. Therefore, we hypothesize that the risk of atherosclerotic CVD can be accurately monitored using carotid ultrasound imaging, predicted using AI-based algorithms, and reduced …

Utility Of Blood Cellular Indices In The Risk Stratification Of Patients Presenting With Acute Pulmonary Embolism., Brett Slajus, Yevgeniy Brailovsky, Iman Darwish, Jawed Fareed, Amir Darki

Division of Cardiology Faculty Papers

Pulmonary embolism (PE) clinical manifestations vary widely, and that scope is not fully captured by current all-cause mortality risk models. PE is associated with inflammatory, coagulation, and hemostatic imbalances so blood cellular indices may be prognostically useful. Complete blood count (CBC) data may improve current risk models like the simplified pulmonary embolism severity index (sPESI) for all-cause mortality, offering greater accuracy and analytic ability. Acute PE patients (n = 228) with confirmatory diagnostic imaging were followed for all-cause mortality. Blood cellular indices were assessed for association to all-cause mortality and were supplemented into sPESI using multivariate logistic regression. Multiple blood …

Physician Assistant Studies Faculty Publications

Public health impacts can be achieved when evidence-based interventions are implemented to those most in need. Too often implementation never or slowly occurs. The community-wide campaign intervention Tu Salud ¡Si Cuenta! has evidence of improving health outcomes related to chronic disease among low-income, Latinos. Using the RE-AIM Framework, this study examined if the scaled-up version of the intervention is associated with improvements in hypertension and obesity in 12 locations. Each element of the RE-AIM framework was examined. For "Effectiveness," we examined outcomes overall and by implementing location. We used linear and logistic regression to assess if exposure in the intervention …

Native Valve Endocarditis Complicated By Abscess Formation Caused By Rothia Mucilaginosa, S Haddad, Y Saade, B Ramlawi, B Kreidieh, B Gilbert, S Rao

Division of Infectious Diseases and Environmental Medicine Faculty Papers

Rothia mucilaginosa is increasingly recognized as an emerging pathogen associated with endocarditis. It has mostly been reported a causative agent for prosthetic valve endocarditis. The previously reported cases of native valve endocarditis caused by this organism only required medical treatment with no surgical intervention. We report a case of R. mucilaginosa native valve endocarditis complicated by abscess formation requiring surgical intervention and review the literature of native valve endocarditis caused by this organism.
