A Mixed-Methods Study: Self-Efficacy And Barriers To Participation In Workplace Wellness Programs, Massiel Perez-Calhoon

Dissertations

America needs a healthy workforce to sustain the country. The scourge of obesity continues to plague Americans despite government initiatives such as the Affordable Care Act and wellness programs in the workplace to combat this epidemic. However, despite initiatives to make America healthy, barriers continued to impede the nation’s health. Lack of awareness and sensitivity to what motivates individual participants versus group participants built formidable barriers to accessing all workplace employees equitably. The purpose of this study was twofold. First, the intent of this study was to explore the relationship between self-efficacy and the impact on participation and engagement ...

Secondary Prevention At The Aswan Heart Centre, Amira Athanasios

GW Research Days 2016 - Present

Cardiovascular disease remains the leading cause of death globally, taking the lives of almost 18 million patients around the world each year. The overwhelming majority of cardiovascular deaths take place in low- to mid-income counties, suggesting that most cardiovascular deaths are preventable. In this study, current literature on secondary prevention of coronary artery disease was analyzed. Specific emphasis was given to preventative measures and successes in low income countries. Based on a literature review, a patient questionnaire to better understand patient adherence to preventative measures was created. This questionnaire focuses on patients receiving dual antiplatelet therapy post acute myocardial infarct ...

Secondary Prevention And Cognitive Function After Stroke: A Study Protocol For A 5-Year Follow-Up Of The Aspire-S Cohort, Daniela Rohde, David Williams, Eva Gaynor, Kathleen E. Bennett, Eamon Dolan, Elizabeth Callaly, Margaret Large, Anne Hickey

Psychology Articles

Introduction Cognitive impairment is common following stroke and can increase disability and levels of dependency of patients, potentially leading to greater burden on carers and the healthcare system. Effective cardiovascular risk factor control through secondary preventive medications may reduce the risk of cognitive decline. However, adherence to medications is often poor and can be adversely affected by cognitive deficits. Suboptimal medication adherence negatively impacts secondary prevention targets, increasing the risk of recurrent stroke and further cognitive decline. The aim of this study is to profile cognitive function and secondary prevention, including adherence to secondary preventive medications and healthcare usage, 5 ...

Abstract:

Background: We performed a retrospective analysis to evaluate the efficacy of VA-ECMO support in cardiogenic shock based on various etiologies.

Methods: We retrospectively analyzed 99 patients supported with VA-ECMO from January 1, 2012 to January 1, 2015. Outcomes included survival to discontinuation of VA-ECMO support and survival to hospital discharge. The etiologies of cardiogenic shock included cardiac arrest (CPR), acute myocardial infarction (AMI), decompensated congestive heart failure (CHF), pulmonary embolism (PE), right ventricular failure (RVF) not secondary to an acute pulmonary embolism, and post-cardiotomy syndrome (PCS). The PCS group was used as a reference group; odds ratios were estimated ...


P23. Elucidation Of The Signaling Pathway Of Mertk, Kyle Taruc 2017 Western University

P23. Elucidation Of The Signaling Pathway Of Mertk, Kyle Taruc

Western Research Forum

Background

Mer Tyrosine Kinase (MERTK) is a receptor which mediates efferocytosis – removal of apoptotic cells by phagocytes such as macrophages. MERTK plays a critical role in homeostasis, with mutations in MERTK associated with the development and progression of atherosclerosis, the buildup of cholesterol-laden plaque in the sub-arterial space. Indeed, one MERTK allele is associated with 66% (heterozygous) to 75% (homozygous) protection from atherosclerosis, while other alleles and SNP’s pre-dispose to atherosclerosis and autoimmunity. Complications resulting from atherosclerosis, including heart attack and stroke, are currently the second leading cause of mortality in Canada. Despite the importance of MERTK in atherosclerosis ...

Using Heart Models For Physiology Teaching And Learning, Sowmya Anjur

Sowmya Anjur

Over the last few decades, there has been a shift in the classroom from a teacher-centered learning environment, with its emphasis on content delivery, to a student-centered environment focused on inquiry learning (http://www.nsta.org/docs/ PositionStatement_Scienti cInquiry.pdf). With the Next Generation Science Standards (NGSS, 2012) being adopted by many states, students are no longer passive listeners, but actively participate in and initiate class discussions (Weimar, 2013). Additionally, recent technological advances have allowed students to acquire information from sources such as the internet which no longer necessitates the teacher giving lectures (Silver- thorn, 2006). The more student-centered learning ...

Up-Regulation Of Junctophilin-2 Prevents Er Stress And Apoptosis In Hypoxia/Reoxygenation-Stimulated H9c2 Cells, Zijun Su

Electronic Thesis and Dissertation Repository

Ischemic heart disease is the leading cause of death, and reperfusion which can restore blood flow is the primary therapy. However, reperfusion can induce further damage to cardiomyocytes, a condition described as ischemia-reperfusion (I/R) injury. I/R is now recognized as a combination determining the final myocardial infarction size. Although the mechanisms underlying I/R-induced cardiac injury remain incompletely understood, emerging evidence suggests that intracellular Ca2+ mishandling during I/R plays a key role in cell death. Junctophilin-2 (JPH2) is a junctional membrane-binding structural protein. It mechanically maintains the fixed distance between the T-tubule and the sarcoplasmic reticulum ...

BACKGROUND: Cardiometabolic (CM) risk factors are heritable and cluster in individuals. We hypothesized that CM risk factors are associated with multiple shared and unique mRNA and microRNA (miRNA) signatures. We examined associations of mRNA and miRNA levels with 6 CM traits: body mass index, HDL-cholesterol and triglycerides, fasting glucose, and systolic and diastolic blood pressures through cross-sectional analysis of 2812 Framingham Heart Study who had whole blood collection for RNA isolation for mRNA and miRNA expression studies and who consented to genetic research. We excluded participants taking medication for hypertension, dyslipidemia, or diabetes. We measured mRNA (n = 17,318; using ...

Von Willebrand Disease, Ramon Misla David 2017 Liberty University

Von Willebrand Disease, Ramon Misla David

The Kabod

Von Willebrand Disease (VWD) is a blood clotting disorder characterized by low levels of the Von Willebrand Factor (VWF) in the blood. VWF is functions to bind platelets and promote clotting of the blood when vascular injury occurs. Therefore, VWD leads to decreased or impaired clotting. There are three main types and four subtypes of VWD (type 1, 2A, 2B, 2N, 2M, and 3). Each type of VWD increases in severity. VWD is diagnosed preliminarily through a personal and family history and physical examination. Upon indications toward the possibility of a bleeding disorder, an initial hemostasis evaluation is performed followed ...

The Crux Of The Heart –– The Closest Approach Of The Right Atrium To The Left Ventricle, Lynn Erickson, David Krum, Hannah Samuel, Anwer Dhala, Jasbir Sra

Jasbir Sra, MD, FACC, Program Director

Background: Accessory pathways, the source of atrioventricular reentry tachycardia, occasionally connect the left ventricle to the right atrium. This is possible because, in some patients, a portion of the right atrium abuts the left ventricle on the posterior wall of the heart, near the mid-coronary sinus. This anatomic region is known as the “crux” of the heart. These accessory pathways can be difficult to ablate because of the unusual and unexpected substrate. While the presence of these accessory pathways is described in the literature, the prevalence of the underlying anatomic substrate is not currently known.

Purpose: To measure the closest ...

Purpose Outcomes in patients with atrial fibrillation who develop acute mesenteric ischemia, and the impact of anticoagulation on complications, are not defined. Methods Patients admitted with acute mesenteric ischemia in the National Inpatient Sample from 2007, with and without atrial fibrillation, were compared for in-hospital outcomes using multivariate regression, and the impact of prior anticoagulation determined. Results Of 48,872 patients with acute mesenteric ischemia, 8,306 had atrial fibrillation, with 680 patients also on anticoagulation. Atrial fibrillation patients were more likely to be older and have hypertension, heart failure, or chronic lung or renal disease. After adjusting for potential ...

Atrial Fibrillation And Stroke In Elderly Patients, Geetanjali Dang, Imaan Jahangir, Jasbir Sra, A. Jamil Tajik, Arshad Jahangir

Jasbir Sra, MD, FACC, Program Director

The increasing prevalence of stroke, with an estimated annual cost of $71.5 billion, has made it a major health problem that increases disability and death, particularly in patients with atrial fibrillation. Although advanced age and atrial fibrillation are recognized as strong risk factors for stroke, the basis for this susceptibility are not well defined. Aging or associated diseases are accompanied by changes in rheostatic, humoral, metabolic and hemodynamic factors that may contribute more to stroke predisposition than rhythm abnormality alone. Several thromboembolism-predisposing clinical characteristics and serum biomarkers with prognostic significance have been identified in patients with atrial fibrillation. Although ...
