Effects Of The Na-Cl Co-Transporter (Ncc) In Western Diet Induced Metabolic And Cardiac Dysfunction, Zachary S. Cutter

Theses and Dissertations

Interleukin-18 (IL-18) is a pro-inflammatory cytokine known to be involved in maintaining metabolic homeostasis; however, also capable of inducing cardiac dysfunction. Additionally, IL-18, has been shown to bind to a novel receptor, the Na-Cl Co-transporter (NCC). We hypothesized that NCC mediates IL-18 metabolic and cardiac signaling in mice. Using male C57BL/6J mice, we compared the metabolic and cardiac function changes after at least 8 weeks of high-saturated fat high sugar diet (Western Diet) in NCC knockout (NCCKO), IL-18 knockout (IL-18KO), and wild-type mice. We show that NCCKO mice have significantly increased body weight gain from baseline, no difference in fasting …

Prevalence And Incidence Of Health Risk Factors Among Adolescent Girls, Kylah Pollard, Mohammed Chowdhury, Sarai Bauguess

The Kennesaw Journal of Undergraduate Research

Heart Disease has many different risk factors, including hypertension (high blood pressure) and high cholesterol. Research has shown that hypertension can be identified as early as adolescence, and preventative measures can be instilled in this age. However, the relationship between hypertension, high cholesterol, race, and income have not been studied in detail among adolescents. The present study analyzed the effects of different health factors on blood pressure and cholesterol levels in Caucasian and African-American girls ages 9-21 years old, the prime of adolescence. The dataset was part of a larger study completed by the National Heart, Blood, and Lung Institute …

Neighborhood Cohesion, Neighborhood Disorder, And Cardiometabolic Risk, Jennifer N. Robinette, Susan T. Charles, Tara Gruenewald

Psychology Faculty Articles and Research

Perceptions of neighborhood disorder (trash, vandalism) and cohesion (neighbors trust one another) are related to residents’ health. Affective and behavioral factors have been identified, but often in studies using geographically select samples. We use a nationally representative sample (n = 9032) of United States older adults from the Health and Retirement Study to examine cardiometabolic risk in relation to perceptions of neighborhood cohesion and disorder. Lower cohesion is significantly related to greater cardiometabolic risk in 2006/2008 and predicts greater risk four years later (2010/2012). The longitudinal relation is partially accounted for by anxiety and physical activity.

Iron Reduction Response And Demographic Differences Between Diabetics And Non-Diabetics With Cardiovascular Disease Entered To A Controlled Clinical Trial, Leo Zacharski, Galina Shamayeva, Bruce Chow

Dartmouth Scholarship

Iron-catalyzed oxygen free radical-induced oxidative stress mediates the pathogenesis of diabetes and cardiovascular disease (CVD). Diabetics (n=473) and non-diabetics (n=804) with CVD entered to a randomized trial of iron (ferritin) reduction by calibrated phlebotomy (www.clinicaltrials.gov, Identifier NCT00032357) had comparable iron measures at entry but diabetics had greater burden of CVD and comorbidities, lower hemoglobin and hematocrit levels, and higher glucose levels than non-diabetics. Entry iron measures were lower in diabetics on hypoglycemic therapy compared to diabetics untreated previously. Diabetics and non-diabetics had comparable iron measures during follow-up. Loess analysis of paired ferritin and hemoglobin, and paired ferritin and glucose levels …

Structural Insights Into The Potency Of Sk Channel Positive Modulators, Young-Woo Nam, Razan Orfali, Tingting Liu, Kunqian Yu, Meng Cui, Heike Wulff, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels play essential roles in the regulation of cellular excitability and have been implicated in neurological and cardiovascular diseases through both animal model studies and human genetic association studies. Over the past two decades, positive modulators of SK channels such as NS309 and 1-EBIO have been developed. Our previous structural studies have identified the binding pocket of 1-EBIO and NS309 that is located at the interface between the channel and calmodulin. In this study, we took advantage of four compounds with potencies varying over three orders of magnitude, including 1-EBIO, NS309, SKS-11 (6-bromo-5-methyl-1H-indole-2,3-dione-3-oxime) and …

Serum Microrna-27b As A Screening Biomarker For Left Ventricular Hypertrophy, Yan Wang, Shuyan Chen, Yanhong Gao, Song Zhang

The Texas Heart Institute Journal

MicroRNA-27b (miR-27b) is frequently upregulated in pressure-overloaded hypertrophic hearts. The clinical implications of aberrant circulating miR-27b in the diagnosis and management of left ventricular hypertrophy warrant study. We investigated whether serum miR-27b is a biomarker for left ventricular hypertrophy (LVH).

We used stem-loop reverse-transcription quantitative polymerase chain reaction techniques to analyze serum miR-27b levels in 200 hypertensive patients with LVH, 100 hypertensive patients without LVH, and 100 healthy volunteers. We found that serum miR-27b levels were significantly higher in the hypertensive patients with LVH than in the hypertensive patients without LVH and in the healthy volunteers. Upon receiver operating characteristic …

Bioresorbable Scaffolds In Spontaneous Coronary Artery Dissection: Long-Term Follow-Up In 4 Patients, Santiago Jesús Camacho Freire, Antonio Enrique Gómez Menchero, Jessica Roa Garrido, Javier León Jiménez, Rosa Cardenal Piris, José Francisco Díaz Fernández

The Texas Heart Institute Journal

Spontaneous coronary artery dissection is a rare condition, and diagnosis and treatment are challenging among patients who present with acute coronary syndrome. Typically, the condition affects young females who have no underlying atherosclerotic disease. To date, few cases of bioresorbable scaffold implantation for the treatment of spontaneous coronary artery dissection have been reported. Therefore, we describe the cases of 4 patients whom we treated with scaffolds. We evaluated the long-term results by using intravascular ultrasound and optical coherence tomographic scanning.

Recurrent Biatrial Myxoma In A 41-Year-Old Woman After Left Atrial Myxoma Resection, Xiaoming Jia, Anjali Kohli, Jane Jarjour, Chung-Jiah Justin Chen, Brendan Gilmore, Rashed Tabbaa, Edward Lee Poythress

The Texas Heart Institute Journal

Bilateral recurrence of atrial myxoma has been reported only a few times. We describe the case of a 41-year-old woman who had undergone left atrial myxoma resection and presented 9 years later with myxomas in both atria. The patient underwent successful resection of both masses with resolution of symptoms. We discuss the phenomenon of recurrent biatrial myxoma.

Role Of Cannabinoid Receptor Type 2 (Cb2) In Late Stage Atherosclerosis, Makenzie Fulmer

Electronic Theses and Dissertations

Atherosclerosis is a chronic inflammatory disorder of medium and large vessels. Immune signaling and dyslipidemia are two of several processes which influence lesion development in atherosclerosis. Cannabinoids, such as those found in marijuana, exert their effects through two cannabinoid receptors, CB1 and CB2. Recent studies using CB2 knockout mice and CB2-selective ligands have shed light on a protective role of CB2 in early stages of atherosclerosis. However, the role of CB2 in advanced stages of atherosclerosis remains unclear. To determine if CB2 plays a role in advanced atherosclerotic lesion composition and progression, we investigated the effects of systemic CB2 gene …

Multimodal Imaging Of Anomalous Left Coronary Artery From The Pulmonary Artery In A 75-Year-Old Woman, Margaret M Fuchs, Rachel J Le, Michael W Cullen, Joseph J Maleszewski, Naser M Ammash

The Texas Heart Institute Journal

Anomalous origin of the left coronary artery from the pulmonary artery is rare and typically results in mitral regurgitation, ventricular arrhythmias, heart failure, and sudden death. The condition most often manifests itself in early childhood, but some individuals are diagnosed much later. We describe the case of a 75-year-old woman with heart failure in whom stepwise multimodal imaging revealed anomalous origin of the left coronary artery from the pulmonary artery.

Assessment Of Chronic Disease To Determine Appropriateness Of Implantable Cardioverter-Defibrillator Therapy, Bilal M. Omery, Maharaj Singh, Randy S. Turkel, Robyn Shearer, Arshad Jahangir, M. Eyman Mortada, Jasbir S. Sra, Indrajit Choudhuri

Journal of Patient-Centered Research and Reviews

Background: Implantable cardioverter-defibrillator (ICD) therapy is considered appropriate when a patient is felt to have a reasonable expectation of 1-year survival. Chronic diseases have been estimated to be associated with greater than 10% annual mortality and may reduce benefits of ICD therapy. Frailty has been estimated to be associated with greater than 20% annual mortality and has been suggested to contraindicate ICD therapy.

Purpose: Determine a risk score that may identify patients in whom ICD implantation may not be appropriate.

Methods: Patients who received an ICD for primary and secondary prevention from 2008 through 2013 at the Aurora Health Care …

Sensitivity Of Current Methods For Diagnosing And Documenting Metabolic Syndrome Within A Large Community-Based Health Care System, Tiffany A. Mullen, Danielle M. Greer, Jennifer T. Fink, Renee E. Walker

Journal of Patient-Centered Research and Reviews

Background: Metabolic syndrome (MetS) is a constellation of metabolic conditions, including abdominal obesity, high blood pressure, high triglyceride level, low high-density-lipoprotein level and high fasting blood glucose level, that increase the risk of developing chronic health conditions. Various combinations of diagnostic criteria have been proposed, including those by the National Cholesterol Education Program Adult Treatment Panel III (ATP III), World Health Organization (WHO) and International Diabetes Foundation (IDF), among others. However, inconsistent use of diagnostic criteria and inadequate scientific evidence supporting use of specific criteria are current problems in health care.

Purpose: Quantify the prevalence of MetS diagnosis within the …

Mechanisms Of Left Ventricular Thrombus Formation In Heart Failure With Reduced Ejection Fraction: Novel Insights From Two-Dimensional Speckle Tracking Echocardiography, Dhruv Chawla, Tracy Hammonds, Tadele Mengesha, Matt Umland, Khawaja Afzal Ammar, Vinay Thohan

Journal of Patient-Centered Research and Reviews

Background: Patients suffering from heart failure with reduced ejection fraction (HFrEF) are at increased risk for left ventricular (LV) thrombus and subsequent thromboembolism, yet anticoagulation is not routinely recommended for left ventricular ejection fraction (LVEF) alone. We sought to determine the role of two-dimensional speckle tracking echocardiography (2D-STE) to quantify regional changes in cardiac function associated with LV thrombus, which may prospectively guide anticoagulation.

Purpose: Help enable cardiovascular clinicians to use 2D-STE to evaluate regional strain patterns among patients with HFrEF with and without LV thrombus. Our results suggest that statistically lower regional longitudinal strain patterns in a well-matched cohort …
