The Effects Of Interleukin-1Β On Cardiac Reserve And Exercise Capacity In The Mouse, Habeebah Z. Vohra

Theses and Dissertations

Heart failure (HF) is characterized by dyspnea, fatigue, and exercise intolerance. Clinical evidence points to increased interleukin-1β (IL-1β) activity in patients with HF, with an IL-1 blockade improving the exercise capacity in HF patients. In healthy mice, recombinant-mouse IL-1β (rmIL-1β) induces acute systolic dysfunction, peaking 4 hours after administration. However, the direct effects of rmIL-1β on exercise capacity are unknown. We hypothesized that rmIL-1β diminishes the exercise capacity in the mouse. Adult mice were trained to run on a treadmill and exercise capacity was assessed before, 4 hours, and 96 hours after intraperitoneal administration of rmIL-1β (3 μg/kg) or vehicle …

Role Of P53 Deficient Clonogenic Endothelial Cells In The Pathogenesis Of Pulmonary Hypertension, Aneel Roy Bhagwani

Theses and Dissertations

Pulmonary Artery Hypertension (PAH) is a progressive disorder of the small vessels of the pulmonary vasculature. It is characterized by occlusive vascular remodeling leading to right heart failure and ultimately death. PAH pathogenesis involves a multifactorial etiology leading to formation of occlusive lesions in small (preacinary) pulmonary arteries. These lesions contain hyper-proliferative, apoptosis resistant endothelial cells (ECs), smooth muscle cells and fibroblasts. ECs play a major role in the development of PAH. These ECs in vascular lesions are primitive and express progenitor cell markers, including CD117 (c-kit).

We have isolated clonally expanded, c-kit+ ECs from the lungs of Green Fluorescent …

Can Erythropoietin Reduce Hypoxemic Neurological Damages In Neonates With Congenital Heart Defects?, Sara Ottolenghi, Giuseppina Milano, Michele Dei Cas, Tina O Findley, Rita Paroni, Antonio F Corno

Faculty, Staff and Student Publications

Congenital heart defects (CHD), the most common cause of birth defects with increasing birth prevalence, affect nearly 1% of live births worldwide. Cyanotic CHD are characterized by hypoxemia, with subsequent reduced oxygen delivery to the brain, especially critical during brain development, beginning in the fetus and continuing through the neonatal period. Therefore, neonates with CHD carry a high risk for neurological comorbidities, even more frequently when there are associated underlying genetic disorders. We review the currently available knowledge on potential prevention strategies to reduce brain damage induced by hypoxemia during fetal development and immediately after birth, and the role of …

Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan

University of the Pacific Theses and Dissertations

The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …

Pericardial Fluid Proteomic Label-Free Quantification Of Differentially Expressed Proteins In Ischemic Heart Disease Patients With Systolic Dysfunction By Nano-Lc-Esi-Ms/Ms Analysis, Junaid Ullah, Satwat Hashmi, Arslan Ali, Faisal Khan, Shahid Ahmed Sami, Nageeb Basir, Syedah Saira Bokhari, Hasanat Sharif, Hesham R. El-Seedi, Syed Ghulam Musharraf

Department of Biological & Biomedical Sciences

Left ventricular systolic dysfunction (LVSD) is common in patients with pre-existing ischemic heart disease (IHD) and myocardial infarction. An untargeted proteomic approach is used to improve the understanding of the molecular mechanisms associated with LVSD and to find out potential proteomic signatures in pericardial fluid. The pericardial fluid of IHD (n = 45) patients was grouped into two categories according to the left ventricular ejection fraction, LVEF ≥45 (n = 33) and LVEF <45 (n = 12), and analyzed by using nano-liquid chromatography–mass spectrometry (nano-LC-MS/MS) technique. The nano-LC-MS/MS analysis resulted in the identification of 709 pericardial fluid (PF) proteins …

The Texas Heart Institute Journal

Del Nido cardioplegic solution (DNC), used chiefly in pediatric patients, rapidly induces prolonged cardiac arrest during cardiac surgery. To determine whether surgical outcomes after coronary artery bypass grafting in a United States military veteran population differed when DNC was used instead of our standard Plegisol cardioplegia, we retrospectively reviewed 155 consecutive operations performed from July 2016 through June 2017. Del Nido cardioplegia was used to induce cardiac arrest in 70 patients, and Plegisol in 85. Compared with the Plegisol group, the DNC group had a shorter mean cardiopulmonary bypass time (96.8 vs 117 min; P48 hours, atrial fibrillation, tracheostomy, reintubation, …

Papillary Fibroelastoma In Differential Diagnosis Of Left Atrial Appendage Masses, Anthony Alozie, Annette Zimpfer, Andreas Erbersdobler, Felix G Meinel, Pascal M Dohmen, Alper Öner

The Texas Heart Institute Journal

Papillary fibroelastomas are benign tumors that usually originate from cardiac valves but may have other endocardial origins. We report the cases of 2 patients in whom left atrial appendage masses were initially diagnosed as thrombus. They were treated for embolic stroke and their symptoms resolved; however, their left atrial appendage masses did not regress. After surgery, histologic analysis of the resected masses revealed papillary fibroelastoma in both cases. We discuss the diagnostic and therapeutic dilemmas encountered in patients with papillary fibroelastomas and cardiac masses other than thrombus.

Pulling Heart Strings: Quality Improvement Algorithm For Temporary Epicardial Pacing Wire Removal Post Cardiac Surgery, Jessica Norman

Doctors of Nursing Practice (DNP) Final Projects, 2020-current

The placement of temporary epicardial pacing wires (TEPW) is considered standard practice post cardiac surgery and is dependent on the patient’s cardiac function intra-operatively and their electrophysiologic profile after weaning from cardiopulmonary bypass (Reade, 2007; Elmistekawy et al, 2016). Complications associated with TEPW removal include myocardial damage, infection, perforation, tamponade, disruption of anastomoses, ventricular arrythmias, and death (Bojar, 2009; Carroll et al, 1998;Timothy & Rodeman, 2004). Currently there is no standard practice on the removal of TEPW and there is wide variation in removal practices involving patients who are routinely on medications such as dual antiplatelet therapies and systemic anticoagulation. …

Implementing Trauma-Informed Care Early In The Lives Of Children And Adults, Carley Clymer

Scholars Week

Throughout the health care industry, providers are failing to recognize the implications that adverse childhood experiences (ACEs) have upon adult health. As a result, these patients not only have to endure these traumas, but they’re also faced with crippling health conditions that accompany them including depression, heart disease and obesity. The prevalence of common high-risk behaviors such as smoking, drinking and illicit drug use can also co-exist with adversity, which leads to an exacerbation of already poor health. This presentation aims to relay the significance of adopting a trauma informed care (TIC) approach early in the lives of clients to …
