Acute Myocardial Infarction Among People Living With Hiv: Comparing Immunological And Virological Control By Hispanic Ethnicity Of The All Of Us Research Program Participants, Eugenio Reina

Honors Undergraduate Theses

In the United States, individuals of Hispanic ethnicity receive disproportionately lower-quality healthcare. These healthcare disparities exacerbate unequal access to quality healthcare services, including disparities in cardiovascular disease (CVD) and human immunodeficiency virus (HIV) care. Research on the role of ethnicity on the CVD outcomes of people living with HIV (PLWH) has been limited. We hypothesize that immunological (CD4+ cell count) and virological (HIV viral load) control may play a role in the development of acute myocardial infarction (AMI) among PLWH, and that Hispanic ethnicity may worsen these outcomes.

To verify our hypotheses, we conducted a retrospective cross-sectional study to investigate …

The Effect Of L-Citrulline Supplementation On Blood Pressure: An Updated Systematic Review And Meta-Analysis Of Randomized Controlled Trials, Vraj Amin

Honors Undergraduate Theses

Cardiovascular disease remains one of the most prevalent diseases in the United States and has remained as the leading cause of death. Large Mendelian randomization studies have found significant correlations between high blood pressure and cardiovascular disease (CVD). In fact, high blood pressure is the single most important independent risk factor for CVD. The purpose of this study was to determine the effect of L-citrulline on blood pressure to determine whether it could be advised as an effective treatment for high blood pressure. L-citrulline is a naturally occurring amino acid that readily converts to L-arginine within the human body. L-arginine …

The Role Of High Mobility Group Box-1 Pathobiology In Angiotensin Ii-Induced Abdominal Aortic Aneurysms, Shayan Mohammadmoradi

Theses and Dissertations--Pharmacology and Nutritional Sciences

Abdominal aortic aneurysms (AAAs) are permanent luminal dilations of the vessel wall that can result in rupture and death. There is currently no evidence-based treatment to prevent or attenuate the development of this devastating condition. Although vascular inflammation is known to be one of the hallmarks of AAA, underlying mechanisms that initiate inflammatory pathways in the aorta are not clearly known. High-mobility group box 1 (HMGB1), a highly conserved nonhistone DNA-binding nuclear protein, may contribute to vascular diseases. Since whole-body genetic deletion of HMGB1 is embryonic lethal, pharmacological approaches have been used to manipulate HMGB1 in mice. However, it remains …

Exploring The Efficacy Of Mir-33 Antagonism In Promoting Regression Of Intracranial Atherosclerosis In A Nonhuman Primate Model, Peter Hecker

Theses and Dissertations--Pharmacology and Nutritional Sciences

Atherosclerosis, characterized by lipid accumulation and arterial inflammation, is a major contributor to global morbidity and mortality. Despite significant progress in understanding atherosclerosis in extracranial arteries, the study of intracranial atherosclerosis (ICAS) has been relatively neglected, despite its crucial role in stroke and vascular cognitive impairment. Challenges related to ICAS, including its location within the cranium and limited availability of suitable animal models, have hindered research progress in this area. Although nonhuman primates (NHPs) are commonly used for studying extracranial atherosclerosis, a comprehensive understanding of ICAS pathophysiology in these animals is lacking. By subjecting NHPs to a high-fat/cholesterol diet, we …

Sex Dimorphisms Of Aldosterone And High Salt Induced Aortic Aneurysms In Mice, Xufang Mu

Theses and Dissertations--Pharmacology and Nutritional Sciences

Aortic aneurysms, a permanent enlargement in the aorta, is a devastating disease with a high mortality rate after rupture. Aortic aneurysms exhibit strong sex dimorphisms: men are at higher risk than women while women experience worse outcomes if diagnosed. Currently, the only intervention is by open surgery or endovascular repair, and no drugs are approved for blunting the disease progression. This highlights the needs for mechanistic studies for sex-specific therapeutic targets.

Our lab established the mouse model in which mineralocorticoid receptor (MR) agonist aldosterone induces aortic aneurysms in the presence of high salt in male mice age-dependently, mimicking the aging …

Modifiable Health Disparities And Cardiovascular Disease Risk Factors In Latino Migrant Seasonal Farmworkers: A Meta-Analysis, Cindy Mendez

Nursing Theses and Dissertations

BACKGROUND: Cardiovascular disease is the leading cause of death in the United States (U.S.). Existing literature concluded that Latino migrant seasonal farmworkers endure higher rates of adverse health disparities and chronic diseases than the general U.S. population. However, research on the Latino migrant seasonal farmworkers’ modifiable health disparities (i.e., alcohol use and smoking) and cardiovascular disease risk factors (i.e., high cholesterol, diabetes mellitus, hypertension, and overweight/obesity) is scarce, particularly studies comparing male and female Latino migrant seasonal farmworkers. PURPOSE: This meta-analysis had two aims. First, examine whether male or female Latino migrant seasonal farmworkers in the U.S. have …

Characterizing Cellular Injury And Inflammation With Aldob-/-Mouse Model Of Mafld, Andy Rashid

All Master's Theses

Metabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. …

Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of …

BACKGROUND: The deSUMOylase sentrin-specific isopeptidase 2 (SENP2) plays a crucial role in atheroprotection. However, the phosphorylation of SENP2 at T368 under disturbed flow (D-flow) conditions hinders its nuclear function and promotes endothelial cell (EC) activation. SUMOylation has been implicated in D-flow-induced endothelial-to-mesenchymal transition (endoMT), but the precise role of SENP2 in counteracting this process remains unclear.

METHOD: We developed a phospho-specific SENP2 S344 antibody and generated knock-in (KI) mice with a phospho-site mutation of SENP2 S344A using CRISPR/Cas9 technology. We then investigated the effects of SENP2 S344 phosphorylation under two distinct flow patterns and during hypercholesteremia (HC)-mediated EC activation.

Thrombotic thrombocytopenic purpura (TTP) secondary to dengue fever is a very unusual occurrence. Both conditions are fatal and can result in significant mortality and morbidity if left untreated. In this case, we present a young lady who suffered dengue fever followed by microangiopathic anemia, thrombocytopenic purpura, and altered sensorium. Investigations revealed microangiopathic hemolysis; there was no evidence of disseminated intravascular coagulation. As soon as, we diagnosed the patient as having TTP, we treated her with serial plasma exchange therapy, steroids, and monoclonal antibodies such as rituximab. The patient responded very well to the treatment and completely recovered from neurological symptoms …

Cytosolic Dna Sensing Protein Pathway Is Activated In Human Hearts With Dilated Cardiomyopathy, Leila Rouhi, Sirisha M Cheedipudi, Benjamin Cathcart, Priyatansh Gurha, Ali J Marian

Faculty, Staff and Student Publications

INTRODUCTION: The genome is constantly exposed to numerous stressors, which induce DNA lesions, including double-stranded DNA breaks (DSBs). DSBs are the most dangerous, as they induce genomic instability. In response to DNA damage, the cell activates nuclear DNA damage response (DDR) and the cytosolic DNA sensing protein (CDSP) pathways, the latter upon release of the DSBs to the cytosol. The CDSP pathway activates NFκB and IRF3, which induce the expression of the pro-inflammatory genes. There is scant data on the activation of the CDSP pathway in human hearts with dilated cardiomyopathy (DCM).

AIM: We aimed to determine expression levels of …

Exercise And Ischemia-Activated Pathways In Limb Muscle Angiogenesis And Vascular Regeneration, Vihang A Narkar

Faculty, Staff and Student Publications

Exercise has a profound effect on cardiovascular disease, particularly through vascular remodeling and regeneration. Peripheral artery disease (PAD) is one such cardiovascular condition that benefits from regular exercise or rehabilitative physical therapy in terms of slowing the progression of disease and delaying amputations. Various rodent pre-clinical studies using models of PAD and exercise have shed light on molecular pathways of vascular regeneration. Here, I review key exercise-activated signaling pathways (nuclear receptors, kinases, and hypoxia inducible factors) in the skeletal muscle that drive paracrine regenerative angiogenesis. The rationale for highlighting the skeletal muscle is that it is the largest organ recruited …

Coronary Heart Disease And Ischemic Stroke Polygenic Risk Scores And Atherosclerotic Cardiovascular Disease In A Diverse, Population-Based Cohort Study, Allison Bebo, Jamie A Jarmul, Mark J Pletcher, Natalie R Hasbani, David Couper, Vijay Nambi, Christie M Ballantyne, Myriam Fornage, Alanna C Morrison, Christy L Avery, Paul S De Vries

Faculty, Staff and Student Publications

The predictive ability of coronary heart disease (CHD) and ischemic stroke (IS) polygenic risk scores (PRS) have been evaluated individually, but whether they predict the combined outcome of atherosclerotic cardiovascular disease (ASCVD) remains insufficiently researched. It is also unclear whether associations of the CHD and IS PRS with ASCVD are independent of subclinical atherosclerosis measures. 7,286 White and 2,016 Black participants from the population-based Atherosclerosis Risk in Communities study who were free of cardiovascular disease and type 2 diabetes at baseline were included. We computed previously validated CHD and IS PRS consisting of 1,745,179 and 3,225,583 genetic variants, respectively. Cox …

Faculty, Staff and Student Publications

Venous thromboembolism is a condition that includes deep vein thrombosis and pulmonary embolism. It is the third most common cardiovascular disease behind acute coronary heart disease and stroke. Over the past few years, growing research suggests that venous thrombosis is also related to the immune system and inflammatory factors have been confirmed to be involved in venous thrombosis. The role of inflammation and inflammation-related biomarkers in cerebrovascular thrombotic disease is the subject of ongoing debate. P-selectin leads to platelet-monocyte aggregation and stimulates vascular inflammation and thrombosis. The dysregulation of miRNAs has also been reported in venous thrombosis, suggesting the involvement …

Mitral Valve Surgery In Patients With An Implanted Amplatzer Septal Occluder: A Review Of 2 Cases, Ufuk Sayar, Nurel Ertürk

The Texas Heart Institute Journal

Surgical approaches for mitral valve exploration vary, with the preferred approach being via the interatrial groove. Data on whether the interatrial groove approach can be used for mitral valve surgery in patients with a previously implanted Amplatzer septal occluder (ASO) (St Jude Medical, an Abbott company) are extremely limited. The authors performed mitral valve surgery using the transatrial septal approach on 2 patients following explantation of an ASO, which significantly impedes the interatrial groove approach. Concomitant surgical procedures with mitral valve replacement, removal of the ASO, and closure of an atrial septal defect with a patch significantly prolonged the cross-clamp …
