Ethnicity Matters: Implications For Understanding And Acting Upon Disparities In Health Affecting Black Men In The United States, Helen V. S. Cole

Dissertations, Theses, and Capstone Projects

Compared to non-Hispanic whites, non-Hispanic blacks have higher rates of mortality from heart disease, cancer, cardiovascular disease, and HIV/AIDS. Black men have a life expectancy approximately 4.7 years than the life expectancy of non-Hispanic white men, due in part to higher prevalence of chronic disease among black men. Many factors are hypothesized to contribute to disparities in health between races, including differences in socioeconomic status; culturally-linked behaviors such as diet, substance use, and physical activity; access to quality healthcare and other resources; and experiences of racism, both institutional and interpersonal. However, in public health research, race is usually treated as …

Targeted Echocardiographic Screening For Latent Rheumatic Heart Disease In Northern Uganda: Evaluating Familial Risk Following Identification Of An Index Case., Twalib Aliku, Craig Sable, Amy Scheel, Alison Tompsett, Peter Lwabi, Emmy Okello, Robert Mccarter, Marshall Summar, Andrea Beaton

Pediatrics Faculty Publications

BACKGROUND: Echocardiographic screening for detection of latent RHD has shown potential as a strategy to decrease the burden of disease. However, further research is needed to determine optimal implementation strategies. RHD results from a complex interplay between environment and host susceptibility. Family members share both and relatives of children with latent RHD may represent a high-risk group. The objective of this study was to use echocardiographic family screening to determine the relative risk of RHD among first-degree relatives of children with latent RHD compared to the risk in first-degree relatives of healthy peers.

METHODOLOGY/PRINCIPAL FINDINGS: Previous school-based screening data were …

Emergency Coronary Artery Bypass Grafting: Indications And Outcomes From 2003 Through 2013, Erin M Schumer, John H Chaney, Jaimin R Trivedi, Paul L Linsky, Matthew L Williams, Mark S Slaughter

The Texas Heart Institute Journal

Emergency coronary artery bypass grafting (CABG) is associated with increased in-hospital mortality rates and adverse events. This study retrospectively evaluated indications and outcomes in patients who underwent emergency CABG.

The Society of Thoracic Surgeons database for a single center (Jewish Hospital) was queried to identify patients undergoing isolated CABG. Univariate analysis was performed.

From January 2003 through December 2013, 5,940 patients underwent CABG; 212 presented with emergency status. A high proportion of female patients (28.2%) underwent emergency surgery. Emergency CABG patients experienced high rates of intra-aortic balloon pump support, bleeding, dialysis, in-hospital death, and prolonged length of stay. The proportion …

Two Cases Of Transcatheter Closure Of Central Aortopulmonary Shunts: One With An Amplatzer Duct Occluder Ii And One With An Amplatzer Vascular Plug I, Ahmet Celebi, Ilker Kemal Yucel, Sevket Balli, Mehmet Kucuk

The Texas Heart Institute Journal

When total correction is not possible in infants who have a cyanotic congenital heart disease, creation of a palliative aortopulmonary shunt is essential. A central aortopulmonary shunt is preferable, because of its technical and hemodynamic advantages. Overcirculation, thrombosis, and stenosis of the shunt are the main postoperative sequelae that necessitate urgent reintervention. Percutaneous transcatheter closure of aortopulmonary shunts can eliminate the need for reoperation and substantially decrease postoperative morbidity and mortality rates. We report our successful transcatheter closures of central aortopulmonary shunts in a 3-month-old infant and a 15-year-old girl, with use of an Amplatzer Duct Occluder II and an …

Fresh Autologous Pericardium To Reconstruct The Pulmonary Valve At The Annulus When Tetralogy Of Fallot Requires A Transannular Patch At Midterm, Shantanu Pande, Jugal K Sharma, C R Siddartha, Anubhav Bansal, Surendra K Agarwal, Prabhat Tewari, Aditya Kapoor

The Texas Heart Institute Journal

Tetralogy of Fallot often requires reconstruction of the right ventricular outflow tract with a transannular patch (TAP), but this renders the pulmonary valve incompetent and eventually leads to right ventricular dysfunction.

We retrospectively evaluated the efficacy of a reconstructed pulmonary valve and annulus in 70 patients who underwent, from December 2006 through December 2010, complete correction of tetralogy of Fallot. We divided the 70 patients into 2 groups in accordance with whether they required (n=50) or did not require (n=20) a TAP. We used autologous untreated pericardium to fashion the TAP and to create both an annulus of the correct …

Endocarditis And Incomplete Endothelialization 12 Years After Amplatzer Septal Occluder Deployment, Allan K Nguyen, Brian A Palafox, Joanne P Starr, Richard N Gates, Farbouch Berdjis

The Texas Heart Institute Journal

A 4-year-old boy had a 15-mm atrial septal defect repaired percutaneously with use of an Amplatzer Septal Occluder. At age 16 years, he presented with a week's history of fever, chills, dyspnea, fatigue, and malaise. Cultures grew methicillin-sensitive Staphylococcus aureus. A transesophageal echocardiogram showed a 1.25 × 1.5-cm pedunculated mass on the left aspect of the atrial septum just superior to the mitral valve, and a smaller vegetation on the right inferior medial aspect of the septum. At surgery, visual examination of both sides of the septum revealed granulation tissue, the pedunculated mass, the small vegetation, and exposed metal …

Subjective Well-Being And Cardiometabolic Health: An 8-11 Year Study Of Midlife Adults, Julia K. Boehm, Ying Chen, David R. Williams, Carol D. Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Individuals who are satisfied and experience frequent positive emotions tend to have reduced risk for coronary heart disease (CHD). However, conflicting evidence exists and little research has investigated whether well-being is associated with early-warning indicators of biological risk that precede CHD. We investigated whether life satisfaction and positive emotions longitudinally predicted reduced risk of incident cardiometabolic conditions and healthier cardiometabolic risk scores, which may provide insight into underlying mechanisms and novel prevention targets.

Methods: Initially healthy men and women (N=754–854) reported their baseline life satisfaction and positive emotions. During follow-up, presence of manifest cardiometabolic conditions was assessed …

Priming Cardiovascular Stem Cells For Transplantation Using Short-Term Hypoxia, Ivan Hernandez

Electronic Theses, Projects, and Dissertations

Conventional medical treatments fail to address the underlying problems associated with the damage inflicted by a coronary event. Thus, the long-term prognosis of patients admitted for heart failure is disheartening, with reported survival rates of 25 percent. Recent advances in stem cell research highlight the potential benefits of autologous stem cell transplantation for stimulating repair in heart tissue. However, a majority of those suffering from cardiovascular diseases are older adults whose autologous cells no longer possess optimum functional capacity. Additional work is needed to identify the optimal cell types or conditions that will promote cardiovascular regeneration across all age groups. …

A Structured Telephonic Transition Program For Heart Failure Patients, Julia E. Robinson

Doctor of Nursing Practice Final Manuscripts

HF is a fatal condition affecting more than 5 million Americans leading to frequent hospitalizations, poor quality of life and death. The annual cost to the healthcare system is approximately $38 billion, ranking HF as one of the costliest conditions to manage. Significant evidence exists that HF self-care management programs improve patient self-care and decrease HF-related readmissions. Current guidelines recommend health professionals provide comprehensive HF education focused on knowledge, skills of management, and self-care behaviors.

The Iowa Model of Evidence Based Practice provided the foundation for the practice change. Structured telephonic support (STS) was based on Bandura’s Self- Efficacy behavior …

Genetic Predisposition And M1 Macrophage Polarization Created By Elastin-Derived Peptides Drive Abdominal Aortic Aneurysm Formation, Matthew A. Dale

Theses & Dissertations

Abdominal aortic aneurysm (AAA) is a dynamic vascular disease characterized by inflammatory cell invasion and extracellular matrix (ECM) degradation. Evidence has demonstrated a profound influence of genetic background on AAA formation. The work presented herein discusses two studies: the first demonstrates how genetic components can enhance the susceptibility to AAA formation and the second demonstrates how ECM degradation enhances AAA progression by influencing inflammatory cell phenotypes. An understanding of the pathways involved in AAA pathogenesis can help not only to identify potential patients at risk of AAA development, a heritable disease in which the incriminating component has yet to be …

The Effect Of Heart Failure Education On Knowledge And Readmission, Sara A. Golden

Evidence-Based Practice Project Reports

Heart Failure (HF) is a chronic progressive disease affecting over 5 million individuals with an expected increase in incidence as the population ages (Yehle & Plake, 2010). The costs associated with managing HF continue to increase and the Centers for Medicare and Medicaid Services (CMS) have attempted to identify ways to improve patient management of HF to reduce the revolving door of hospital readmissions and decrease expenditures. According to 2006 data, as many as one fourth of the Medicare beneficiaries discharged from acute care to skilled nursing facilities (SNF) were readmitted to the hospital within 30 days and the majority …

Routine Screening For Abdominal Aortic Aneurysm: Is It For Everyone?, Catherine E. Nowak

Physician Assistant Capstones, 2016 to 2019

Objective: Determine whether routine abdominal ultrasound screening in all men ages 65 and over, not just those who are symptomatic or at risk, would be beneficial in reducing the mortality rate from abdominal aortic aneurysms (AAA). Design: Systematic literature review. Methods: The clinical question investigated is whether routine ultrasound screening of AAA for men over age 65 reduces AAA-related mortality as compared to not routinely screening. Searches were done through PubMed using the keywords: screening, abdominal aortic aneurysm, reduce, and mortality. Citations used by the USPSTF AAA screening guidelines were also added to the literature search. In PubMed, further limitations …

National Institute Of Health Stroke Scale (Nihss) Inter-Rater Reliability And Confidence Among Nihss Certified Nurses: Implementation Of A Standardized Patient Simulation, Kelly J. Trieglaff

Evidence-Based Practice Project Reports

The National Institute of Health Stroke Scale (NIHSS) is the most common stroke assessment used by nurses. Nurses certified on the NIHSS do not consistently demonstrate inter-rater reliability nor are they confident when assessing stroke patients using the tool (Josephson, Hills, Johnston, 2006). This EBP project evaluated a standardized patient simulation for maintaining inter-rater reliability and confidence in NIHSS certified nurses. A literature review showed that a decrease in inter-rater reliability occurs within four weeks to three months of NIHSS certification. A single cohort of intensive care nurses and emergency department nurses used the NIHSS tool in a standardized patient …

Association Of Self-Care Confidence And Hospital Readmission Following Student Nurse Led Congestive Heart Failure Transitional Care Project, Peyton A. Phelps

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Abstract

Over 5 million Americans have been diagnosed with heart failure, and that number is growing. This disease is burdensome to the patient as it lessens their quality of life and to the healthcare system due to costliness and frequent readmissions. This study aims to evaluate if a student nurse led transitional care program can increase patient self-care confidence, in turn reducing 30 day hospital readmission rates. Twenty patients completed the Self Care of Heart Failure Index before and after a 14-week transitional care program. These reported data were compared using a paired samples t-test. There was not a …

This study proposed use a student led transitional care program in providing home care to NYHA functional class II and III CHF patients. It evaluated the impact of the program on their quality of life as measured by the Minnesota Living with Heart Failure Questionnaire© (MLWHFQ), the percentage of patients requiring readmission to the hospital within 30 days of initial hospitalization, and healthcare utilization. Thirty-six …

The Effects Of Smoking On The Calcification Of The Aortic Valve, Brittany Pendergraft

Biological Sciences Undergraduate Honors Theses

Calcific Aortic Valve Disease is responsible for approximately 28,000 deaths annually and the complete mechanism is not completely understood. The disease is known to be effected by an inflammatory response, osteogenic response and an oxidative stress response that leads to thickening and mineralization of the aortic valve. Originally, this disease was thought to be brought on by age and deterioration of the valve but these rapid stress responses when the valve is disrupted by biochemical and mechanical stress has led to its classification as an active disease. Smoking has been shown to have many of the same effects experienced by …

The Effects Of Pulmonary Hypertension In Diabetic Zucker Rats On Pulmonary Vascular Contraction And Right Ventricular Size, Michael Franzetti

Biological Sciences Undergraduate Honors Theses

Pulmonary hypertension is a life-threatening disease that is identified by a resting mean pulmonary arterial pressure over 25 mmHg and established by right heart catheterization (Saglam et al., 2015). The symptoms commonly associated with pulmonary hypertension include fatigue, dyspnea, syncope, and chest pain, which severely limit quality of life in diagnosed patients (Saglam et al., 2015). According to recent studies in patients with pulmonary hypertension, the one, three and five year mortality rates are 8%, 25%, and 34%, respectively (Burudpakdee, Shah, Joish, Divers, & Yaldo, 2014). Although some advances have been made in therapies for pulmonary hypertension, the prognosis is …

The Eleanor Mann School of Nursing Undergraduate Honors Theses

After diagnosis, management of congestive heart failure (CHF) can pose quite a struggle to many patients, since it requires that lifestyle changes be implemented into their daily life. Patients require the sufficient knowledge and education in order to best manage symptoms and improve their quality of life after being diagnosed. Use of Patient Knowledge of Self-care activities in Congestive Heart Failure^© (PaKSAC) survey in transitional care programs could identify patient gaps in knowledge, as well as decreasing acute care service use. The purpose of this research study was to investigate the knowledge level of CHF patients at the time …

Programming Heart Disease: Does Poor Maternal Nutrition Alter Expression Of Cardiac Markers Of Proliferation, Hypertrophy, And Fibrosis In Offspring?, Cathy Chun

Honors Scholar Theses

Maternal malnutrition can affect fetal organogenesis, metabolic processes, and factors involved in developmental regulation. Of the many physiological effects poor maternal nutrition can induce in offspring, one of the most important organs affected is the heart. Cardiovascular disease has been associated with poor maternal diet. It also been suggested that hypertension can originate during impaired intrauterine growth and development. Hypertension can trigger hypertensive heart disease and is associated with numerous heart complications. We hypothesized that poor maternal nutrition would alter critical growth factors associated with normal heart development, specifically, insulin-like growth factor (IGF)-1, IGF-2, transforming growth factor (TGF)β, and connective …

Diffusion Modeling And Device Development For Peritoneal Membrane Oxygenation, Liana Hatoum

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Acute respiratory distress syndrome (ARDS) is a pulmonary disease that causes hypoxemia and respiratory failure. The mortality rate for ARDS ranges between 27% and 45%. Current treatments including mechanical ventilation and extracorporeal membrane oxygenation (ECMO) are often associated with high risk complications including barotrauma, infection, thrombosis, and hemorrhage. Alternative pulmonary support techniques are needed to improve the survival rate of patients suffering from ARDS. Previous studies introducing pure O₂ gas, perfluorocarbons and red blood cells into the intraperitoneal (IP) cavity have reported no effect or only a mild increase in oxygenation. Here we report peritoneal membrane oxygenation (PMO) using …
