The Impact Of Circadian Misalignment On Cardiometabolic Health, Cynthia Marie Mills

Physician Assistant Scholarly Project Papers

The circadian system is important in all living organisms because it generates a 24-hour rhythm for physiological and behavioral processes enabling anticipation and adaptation to daily changes in the environment. The prevalence of cardiometabolic diseases, which are linked to lifestyle choices, has been rising at an alarming rate. Modernization and globalization are two of many factors to blame for lifestyle changes resulting in circadian disruption. The purpose of this literature review is to explore circadian misalignment with regards to its mechanism and impact on cardiometabolic health and to determine possible interventional measures. The primary focus is on lifestyle change, particularly …

Pre-Participation Physical Examination: Are Current Cardiovascular Recommendations Enough?, Steven Jacob Pietrusza

Physician Assistant Scholarly Project Papers

Inclusion of screening electrocardiograms (EKGs) during pre-participation physical examination has been a topic of debate for some time. There is unquestioned usefulness in the ability of a well-trained health care provider in using EKG to identify cardiac abnormalities. Further, there have been several contemporary EKG criteria published that increase specificity and sensitivity of detection of disease. However, these criteria do not account for athletes less than 14 years of age, and that demographic represents a large portion of patients seeking pre-participation screenings in the United States. The lack of research into pediatric cardiac remodeling secondary to activity, coupled with the …

The Efficacy And Safety Of Statins In The Primary Prevention Of Cardiovascular Disease, Kayla M. Ashton

Physician Assistant Scholarly Project Posters

Atherosclerotic plaques can form in the blood vessels from particles of cholesterol. These plaques are a major cause of cardiovascular disease and have the ability to result in fatal cardiovascular events. In researching this topic, PubMed, the Cochrane Library, DynaMed, and ClinicalKey were all utilized in finding articles published from 2002 to 2018. There are several organizations with conflicting guidelines recommending the use of statin medications in the primary prevention of cardiovascular disease. The research evaluated discovers data is inconclusive on the benefit of statin medications in this primary prevention as well as the safety of long-term statin use. Some …

Systemic Therapy Versus Catheter Directed Techniques For The Treatment Of Acute Massive Pulmonary Embolism, Lawrence Duane Lee

Physician Assistant Scholarly Project Posters

•Acute massive pulmonary embolism is characterized by obstruction of the pulmonary arterial tree that exceeds 50% of the cross-sectional area causing acute and severe cardiopulmonary failure from right ventricular overload.

•Systemic thrombolytic therapy is recommended as standard, first-line treatment in patients with massive pulmonary embolism unless contraindicated and catheter directed therapies, including low dose thrombolytic administration directly into thrombus and mechanical thrombectomy can be adjunctive or used as an alternative to systemic treatments.

Altura, Asefa Gebrewold, Anthony Carella, Nilank C. Shah, Bella T. Altura

Touro College of Osteopathic Medicine (Middletown) Publications and Research

It has been demonstrated in numerous human and animal studies that audiogenic stress (AS) can induce elevation of arterial blood pressure and cardiac damage and that noise –induced hearing loss may be associated with alterations in magnesium (Mg) metabolism. Our laboratories, over a period of approximately 40 years, have been investigating why AS causes high blood pressure and cardiac damage. This review focuses on a number of newer discoveries on why AS causes dysfunctions of the cardiovascular system (CVS) This review discusses the pivotal physiological and biochemical importance of Mg to body health and the fact that most Americans and …

Pathogenic Mechanisms Of Takotsubo Cardiomyopathy Or Broken Heart Syndrome, Devorah Leah Borisute

The Science Journal of the Lander College of Arts and Sciences

Takotsubo Cardiomyopathy (TTC) is a temporary heart-wall motion abnormality with the clinical presentation of a myocardial infarction. Found predominantly in postmenopausal women, TTC most often appears with apical ballooning and mid-ventricle hypokinesis. Often induced by an emotional or physical stress, TTC is reversible and excluded as a diagnosis in patients with acute plaque rupture and obstructive coronary disease. The transient nature and positive prognosis of this cardiomyopathy leaves a dilemma as to what precipitates it. This paper explores the theories of the pathogenesis of TTC including coronary artery spasm, microvascular dysfunction, and catecholamine excess. A thorough analysis of the pathogenesis …

Predictors Of Arterial Stiffness In Law Enforcement Officers, Jason Michael Keeler

Theses and Dissertations--Kinesiology and Health Promotion

The prevalence of cardiovascular disease (CVD) among law enforcement officers (LEOs) is slightly higher than the general population. Furthermore, the prevalence of CVD doubles among LEOs following retirement compared to the general population. The measure of arterial stiffness serves as an independent risk factor that has prognostic value for future incidence of CVD. However, there is limited research on lifestyle, occupational, and demographic factors that may be associated with increased arterial stiffness in LEOs. Therefore, the purpose of this investigation was to compare the level of arterial stiffness among LEOs versus the general population and to identify lifestyle, occupational, and …

Adrenergic Stimulation In Acute Hyperglycemia: Effects On Cellular And Tissue Level Murine Cardiac Electrophysiology, Sridevi Thyagarajan

Theses and Dissertations--Biomedical Engineering

Cardiovascular complications associated with elevated levels of glucose in the blood (Hyperglycemia, HG) is a growing health concern. HG is known to be associated with a variety of cardiovascular morbidities including higher incidence of electrical disturbances. Although effects of chronic HG have been widely investigated, electrophysiological effects of acute hyperglycemia are relatively less known. Further, hyperglycemic effects on adrenergic response is not widely investigated. We used excised ventricular tissues from mice to record trans-membrane potentials during a variety of pacing protocols to investigate cellular/tissue level electrophysiological effects of acute hyperglycemia and adrenergic stimulation (1µM Isoproterenol, a β-adrenergic agonist). A custom …

Role Of Sex Chromosomes In Sexual Dimorphism Of Angii-Induced Abdominal Aortic Aneurysms, Yasir Alsiraj

Theses and Dissertations--Pharmacology and Nutritional Sciences

Abdominal aortic aneurysms (AAAs), a permanent dilation in the abdominal region of the aorta, is a highly sexually dimorphic disease. AAAs prevalence is ranging from 4-10 fold higher in males than females. Defining the mechanistic basis for reduced (in females) or increased (in males) AAA formation and progression may uncover potential therapeutic targets. The majority of studies examining sexual dimorphism focus on the role of sex hormones. However, genes residing on sex chromosomes, in addition to sex hormones, may contribute to sexual dimorphism of AAAs. For example, the X chromosome contains about 5% of the whole genome, but the role …

Mechanisms And Potential Therapy On Disrupted Blood Pressure Circadian Rhythm In Diabetes, Tianfei Hou

Theses and Dissertations--Pharmacology and Nutritional Sciences

Arterial blood pressure (BP) undergoes a 24-hour oscillation that peaks in the active day and reaches a nadir at night during sleep in humans. Reduced nocturnal BP fall (also known as non-dipper) is the most common disruption of BP circadian rhythm and is associated with increased risk of untoward cardiovascular events and target organ injury. Up to 75% of diabetic patients are non-dippers. However, the mechanisms underlying diabetes associated non-dipping BP are largely unknown. To address this important question, we generated a novel diabetic db/db-mPer2^Luc mouse model (db/db-mPer2^Luc) that allows quantitatively measuring of mPER2 protein oscillation …

Controlling Platelet Secretion To Modulate Hemostasis And Thrombosis, Smita Joshi

Theses and Dissertations--Molecular and Cellular Biochemistry

Upon vascular injury, activated blood platelets fuse their granules to the plasma membrane and release cargo to regulate the vascular microenvironment, a dynamic process central to platelet function in many critical processes including hemostasis, thrombosis, immunity, wound healing, angiogenesis etc. This granule- plasma membrane fusion is mediated by a family of membrane proteins- Soluble N-ethyl maleimide Attachment Receptor Proteins(SNAREs). SNAREs that reside on vesicle (v-SNAREs) /Vesicle-Associated Membrane Proteins(VAMPs) interact with target/t-SNAREs forming a trans-bilayer complex that facilitates granule fusion. Though many components of exocytic machinery are identified, it is still not clear how it could be manipulated to prevent …

Workplace Standing Desks And Arterial Stiffness, Ian Greenlund

Dissertations, Master's Theses and Master's Reports

Many jobs in today’s society require sitting at a desk with little physical activity. Individuals who engage in ten hours of sedentary behavior per day double their CVD risk. Standing desks are thought to decrease sedentary time and improve cardiovascular health. Acute use of standing desks is shown to lower PWV. However, chronic effects remain unknown. Forty eight participants qualified as seated (19 females, 5 males: age 41 ± 2 years, BMI 25 ± 1 kg/m²) or standing (21 females, 3 males: age 45 ± 2 years, BMI 25 ± 1 kg/m²) groups based on habitual …

Health Systems Readiness For Adopting Mhealth Interventions For Addressing Non-Communicable Diseases In Low- And Middle-Income Countries: A Current Debate, Anam Shahil Feroz, Muhammad Masood Kadir, Sarah Saleem

Community Health Sciences

In low-and-middle-income countries, epidemiologic transition is taking place very rapidly from communicable diseases to non-communicable diseases. NCDs mortality rates are increasing faster and nearly 80% of NCDs deaths occur in LMICs. Existing weak health systems of LMICs are undergoing a devastating human and economic toll as a result of increasing treatment costs and losses to productivity from NCDs. At the same time, the increasing penetration of mobile phone technology and the spread of cellular network and infrastructure have led to the introduction of the mHealth field. While mHealth field offers a great promise to prevent and control non-communicable diseases in …

Knockdown Of Heparan Sulfate Via Ndst1 Knockout Does Not Inhibit Mouse Aortic Endothelial Cell Alignment In-Vivo, John Diaz De Leon Iii

Dissertations and Theses

Atherosclerotic plaque localizes in predictable areas such as arches and bifurcations which are characterized by disturbed flow patterns and the resulting damage and dysfunction to the endothelium. Endothelial cells (ECs) under sustained laminar flow align in the direction of flow; however, under disturbed flow conditions, ECs sustain damage to their glycocalyx (GCX) which results in unaligned and rounder cells. An investigation into the role of NDST1 sulfation of heparan sulfate (HS), a key component of many proteoglycans which make up the GCX, was conducted. The descending aortas (DAs) of transgenic mice with conditional knockouts (KOs) of NDST1 in vascular ECs …

Age-Dependent Changes In Oxygen Supply And Demand Of Rat Spinotrapezius Muscle, Sami C. Dodhy

Theses and Dissertations

Because of the aerobic nature of cellular metabolism in mammalian organisms, a continuous supply of oxygen is necessary to maintain normal physiological function. As organisms age, their metabolic rates generally decline and there are accompanying alterations in the structure and function of the microcirculation, as this part of the cardiovascular system is especially important for oxygen exchange. The overall Oxygen Transport System can be considered as being composed of two complementary components: one for Oxygen Demand and one for Oxygen Supply. The purpose of the current work is to describe the age-dependent changes in both oxygen demand and oxygen supply …

Counterregulatory Effects Of Ptx3 On Inflammation And Cellular Aging, Aaron L. Slusher

Theses and Dissertations

Pentraxin 3 (PTX3) is a vital regulator of innate immune function that has been shown to counterregulate pro-inflammatory signaling and protect against the development of cardiovascular disease (CVD). Less is known about how PTX3 may mitigate against CVD risk by regulating the pro-inflammatory response at the cellular level. Therefore, this dissertation details four manuscripts which aimed to examine the capacity of PTX3 to regulate the innate immune response of peripheral blood mononuclear cells (PBMCs) isolated from healthy adults. Manuscript 1 examined the capacity of PTX3 to alter the inflammatory milieu following in vitro stimulation of isolated PBMCs with the pro-inflammatory …
