Cardiovascular Tissue Remodeling Of Preeclampsia, Rachel Metz

Williams Honors College, Honors Research Projects

Preeclampsia is a hypertensive disorder of pregnancy that leads to a multitude of problems for the mother and fetus during and after pregnancy. While the effects on the mother's body after pregnancy are often overlooked, preeclamptic mothers are prone to cardiovascular diseases from the great deal of stress experienced through the duration of a preeclamptic pregnancy. The associated high blood pressure causes cardiac muscle to work a great deal harder in an attempt to successfully perfuse tissues adequately. This increase in prolonged stress leads to remodeling of the cardiovascular tissues-significantly increasing the risk of heart issues in life beyond the …

Accounting For The Uncertainty Due To Chemicals Below The Detection Limit In Mixture Analysis, Paul M. Hargarten

Theses and Dissertations

Humans are exposed to multiple chemicals every day. Epidemiological studies have shown that chemical mixtures are associated with cancers, allergies, neurodevelopmental disorders, and other adverse health effects. To assess these associations, investigators are increasingly using chemical mixture approaches like weighted quantile sum (WQS) regression. In these studies, the research objectives are to determine whether a mixture of correlated chemicals is associated with an adverse health outcome and to identify the important chemicals. However, as experimental equipment measures each exposure to a chemical-specific detection limit, the exposures are unknown between zero and the detection limit. Indeed, the number of exposures below …

Don't Just Check The Box: Check Your Athlete's Heart: Adding A 12-Lead Ecg To Pre-Participation Screening To Identify High Risk Of Sudden Cardiac Arrest In Male High School Athletes, Shannon King

DNP Projects

PURPOSE: Sudden cardiac arrest (SCA) continues to be the leading cause of death in male high school athletes participating in competitive sports. There is gap in the current preventative screening practice of history and physical alone. The purpose of this project is to evaluate adding a 12-lead electrocardiogram (ECG) to pre-participation screening captures cardiac abnormalities that identify male athletes at a higher risk for developing SCA. METHODS: A descriptive secondary analysis design to determine the incidence of cardiac abnormalities detected with the addition of a 12-lead ECG during pre-participation screenings (annual sports physical) of high school-aged male athletes. The study …

The Effects Of A Plant-Based Diet On Inflammation Of Patients With Cardiac Disease, Rachel L. Butcher

Honors Undergraduate Theses

Cardiac disease is the primary cause of death in the United States of America (CDC, 2017). Despite ongoing efforts and investments to improve cardiac health in the United States, most of the population will suffer from cardiovascular diseases. There is a multitude of research supporting that diet can contribute to cardiac disease, but it is less known that diet can greatly contribute to regulation and reversal of cardiovascular disease processes (Huang et al., 2012; Satija et al., 2017; Kim et al., 2019). Existing research supports the efficacy of plant-based diets to manage and reverse certain cardiac diseases (Tuso et al., …

Review Of The Scientific Literature On Young Adults Related To Cardiovascular Disease Intervention, Dieu-My T. Tran, Angela Sojobi

Nursing Faculty Research

Many young adults are at risk for cardiovascular disease related to their behavioral choices. Irresponsible alcohol consumption, tobacco smoking, sedentary lifestyle, poor dietary habits, and excessive weight gain are some of the behaviors that put young adults at risk. The Centers for Disease Control and Prevention identified that 15% of young adults are diagnosed with chronic illnesses related to their behavioral choices. The purpose of this review is to identify, in the literature, interventions that are currently available to young adults and evaluate the adequacy and effectiveness of those interventions. An extensive electronic search was conducted using CINAHL, EBSCOhost, Cochrane, …

Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone

UNF Graduate Theses and Dissertations

Purpose Examine the relationships between high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and soluble tumor necrosis factor-α receptor-1 (sTNF-R1) and the cumulative risk of heart failure with reduced (HFrEF) and preserved (HFpEF) ejection fractions in a diverse, population-based sample. Methods Study sample included 6,814 adult (45-84 years of age) men and women who participated in the Multi-Ethnic Study of Atherosclerosis and were free of cardiovascular disease at baseline. Cox regression was used to calculate the hazard ratios (HR) associated with elevated baseline hs-CRP (> 3-10 mg/L), IL-6 (> 75^th percentile) and sTNF-R1 (> 75^th percentile) and risk of overall …

The Effect Of Hibiscus.Sabdariffa. L On Blood Pressure And Arterial Stiffness In Humans, Basirat Tolulope Shittu

Dissertations, Master's Theses and Master's Reports

Cardiovascular diseases (CVD) are the foremost cause of death worldwide. The main risk factor for CVD is uncontrolled hypertension (HTN). The prescription of only anti-hypertensive regimens in the management of HTN is becoming more challenging due to the high cost and adverse effects linked to the persistent usage of the drugs. Eighteen participants completed the study by consuming 2g of Hibiscus sabdariffa or oolong tea twice daily for six weeks. We lost an additional twelve participants in the study due to the COVID-19 pandemic. Central arterial stiffness was analyzed as cfPWV using applanation tonometry technique. The HS tea intervention (n=11) …

Large Sinus Of Valsalva Aneurysm Complicated By Thrombus Formation, Milan Ravishankar, Ali Ghergherehchi, Jing Liu, Ernesto Jimenez, Umair Khalid

Faculty, Staff and Students Publications

Sinus of Valsalva aneurysm (SOVA) is an unusual cardiac anomaly that is potentially fatal with rupture. It is often asymptomatic but has various presentations. We describe a case of a 67-year-old male who presented with atypical chest pain. Transthoracic echocardiogram and cardiac computed tomography scan confirmed a large SOVA complicated by thrombus formation and compression of the left atrium and left ventricular outflow tract. The patient successfully underwent a Bentall procedure-surgical aortic aneurysm repair with mechanical aortic valve conduit. We discuss several clinical decision-making branch points to highlight the complexity of managing this condition. Even in asymptomatic or minimally symptomatic …

Extracellular Mitochondria Released From Traumatized Brains Induced Platelet Procoagulant Activity, Zilong Zhao, Yuan Zhou, Tristan Hilton, Fanjian Li, Cha Han, Li Liu, Hengjie Yuan, Ying Li, Xin Xu, Xiaoping Wu, Fangyi Zhang, Perumal Thiagarajan, Andrew Cap, Fu-Dong Shi, Jianning Zhang, Jing-Fei Dong

Coagulopathy often develops soon after acute traumatic brain injury and its cause remains poorly understood. We have shown that injured brains release cellular microvesicles that disrupt the endothelial barrier and induce consumptive coagulopathy. Morphologically intact extracellular mitochondria accounted for 55.2% of these microvesicles, leading to the hypothesis that these extracellular mitochondria are metabolically active and serve as a source of oxidative stress that activates platelets and renders them procoagulant. In testing this hypothesis experimentally, we found that the extracellular mitochondria purified from brain trauma mice and those released from brains subjected to freeze-thaw injury remained metabolically active and produced reactive …

Lisinopril-Induced Angioedema In A Patient With Plasma Prekallikrein Deficiency, Swapan K Dasgupta, Stefanie Rivera, Perumal Thiagarajan

Faculty, Staff and Students Publications

Angiotensin-converting enzyme (ACE) inhibitors are extensively prescribed to treat patients with hypertension, congestive heart failure, and diabetic nephropathy. A small fraction of these patients (approximately 0.7%) develop angioedema, manifested by swelling of the lips and oropharynx. Angioedema of oropharynx is a medical emergency that can lead to asphyxiation and death. The angioedema is due to bradykinin generated from high molecular weight kininogen by kallikrein, which is derived from plasma prekallikrein by action of the factor XIIa, factor Xia, or prolylcarboxypeptidase. Bradykinin induces vasodilation and increased vascular permeability. ACE is the major degrading enzyme of bradykinin in the intravascular department. ACE …
