The Obesity Epidemic, Lenka Kollar, Evienne Epifano, Molly Mckneight, Jeff Miskovich, Heather Moore

Student Papers in Public Policy

The incidence of chronic, noncommunicable diseases, such as heart disease, is increasing at an alarming rate on the global scale. The growing prevalence of overweight and obesity have led to an upsurge in cases of diabetes and other obesity-related diseases. About 18 million people die every year from heart disease, of which diabetes and obesity are major predisposing factors. Worldwide, more than 1.1 billion adults are overweight, 312 million of which are obese. The number of children that are overweight or obese is also growing (Hossain, Parvez et al.). Obesity, and the associated diseases, has become a worldwide epidemic and …

A Literature Review Of The Health Effects Of A Plant Based Diet Versus An Animal Based Diet, James Cote

Senior Honors Theses

Health and nutrition can mean a myriad of things to many people in today’s culture. The majority of the time people are unaware of the proper nutrients their body needs and how to get them from food. This thesis will seek to expose the health benefits that are associated with consuming a raw plant-based die, offering a more profound and encompassing view on nutrition. Investigating further into today’s most common diseases such as diabetes, heart disease, obesity, cancer and autoimmune disorders, it will seek to discover and answer why we have so many health issues. This thesis will discuss the …

Design And Implementation Of Wireless Point-Of-Care Health Monitoring Systems: Diagnosis For Sleep Disorders And Cardiovascular Diseases, Se Chang Oh

Graduate Theses and Dissertations

Chronic sleep disorders are present in 40 million people in the United States. More than 25 million people remain undiagnosed and untreated, which accounts for over $22 billion in unnecessary healthcare costs. In addition, another major chronic disease is the heart diseases which cause 23.8% of the deaths in the United States. Thus, there is a need for a low cost, reliable, and ubiquitous patient monitoring system. A remote point-of-care system can satisfy this need by providing real time monitoring of the patient's health condition at remote places. However, the currently available POC systems have some drawbacks; the fixed number …

Oxidation Of Thrombomodulin Methionine 388 In Cigarette Smokers, Samrat B. Thapa

Graduate Theses and Dissertations

This work tested the hypothesis that oxidation of methionine 388 in thrombomodulin is higher in cigarette smokers, and thus a likely contributor towards the hypercoagulable state in smokers. Thrombomodulin, a protein cofactor found on endothelial cell surfaces, regulates the activity of thrombin. Thrombin bound to thrombomodulin no longer converts fibrinogen to fibrin, but instead activates Protein C which, in turn, stops the coagulation cascade by inactivation of clotting factors. The oxidation of methionine 388 of thrombomodulin has been shown in vitro to dramatically decrease the anticoagulant cofactor activity of thrombomodulin. The blood of cigarette smokers is more prone to clot …

Liposomal Fasudil, A Rho-Kinase Inhibitor, For Prolonged Pulmonary Preferential Vasodilation In Pulmonary Arterial Hypertension, Vivek Gupta, Nilesh Gupta, Imam H. Shaik, Reza Mehvar, Ivan F. Mcmurty, Masahiko Osa, Eva Nozik-Grayck, Fakhrul Ahsan

Pharmacy Faculty Articles and Research

Current pharmacological interventions for pulmonary arterial hypertension (PAH) require continuous infusions, multiple inhalations, or oral administration of drugs that act on various pathways involved in the pathogenesis of PAH. However, invasive methods of administration, short duration of action, and lack of pulmonary selectivity result in noncompliance and poor patient outcomes. In this study, we tested the hypothesis that encapsulation of an investigational anti-PAH molecule fasudil (HA-1077), a Rho-kinase inhibitor, into liposomal vesicles results in prolonged vasodilation in distal pulmonary arterioles. Liposomes were prepared by hydration and extrusion method and fasudil was loaded by ammonium sulfate-induced transmembrane electrochemical gradient. Liposomes were …

Testosterone, Cardiovascular, Men, Trial, Lin Xu, Guy Freeman, Benjamin J. Cowling, Mary Schooling

Publications and Research

Background
Testosterone therapy is increasingly promoted. No randomized placebo-controlled trial has been implemented to assess the effect of testosterone therapy on cardiovascular events, although very high levels of androgens are thought to promote cardiovascular disease.

Methods
A systematic review and meta-analysis was conducted of placebo-controlled randomized trials of testosterone therapy among men lasting 12+ weeks reporting cardiovascular-related events. We searched PubMed through the end of 2012 using “(“testosterone” or “androgen”) and trial and (“random*”)” with the selection limited to studies of men in English, supplemented by a bibliographic search of the World Health Organization trial registry. Two reviewers independently searched, …

Awareness, Treatment And Control Of Hypertension In Kenya, Jacob Kariuki, Eileen M. Stuart-Shor, Samuel Kimani, James Muchira, Jessica Demita, Heather Milton, Mercy Kamau, Vincent Mutuma, Darren Golden, Peris Kariuki

Office of Community Partnerships Posters

The emerging epidemic of hypertension (HTN) in sub-Saharan Africa is predicted to worsen. Uncontrolled HTN is associated with CVD, high morbidity and premature mortality; hence early detection, treatment and control of HTN is critical to reduction of the associated sequelae. The study was guided by the Social Ecological Model and principles of Community Based Participatory Research.

Global Risk Assessment Of Cardiovascular Disease In Resource Constrained Settings, Jacob Kariuki, Eileen M. Stuart-Shor, Libin Zhang, Annya Volkova, Jaime Halliday, Shannon Sayer, Jessica Demita, Darren Golden, James Muchira, Samuel Kimani, Faith Maina

Office of Community Partnerships Posters

Cardiovascular disease (CVD) is an emerging problem in Sub-Saharan Africa. Many current guidelines recommend using global risk assessment (GRA) to quantify the risk for developing CVD and to guide treatment and policy. Most GRA tools require lipid measures which are not readily available in resource-constrained settings. Of the 3 most published non-laboratory based tools: Gaziano and Framingham substitute BMI for cholesterol; WHO does not include BMI or cholesterol.

Age-Period-Cohort Projections Of Ischaemic Heart Disease Mortality By Socio-Economic Position In A Rapidly Transitioning Chinese Population, Irene O.L. Won, Benjamin J. Cowling, Gabriel M. Leung, Mary Schooling

Publications and Research

Background
With economic development and population aging, ischaemic heart disease (IHD) is becoming a leading cause of mortality with widening inequalities in China. To forewarn the trends in China we projected IHD trends in the most economically developed part of China, i.e., Hong Kong.

Methods
Based on sex-specific IHD mortality rates from 1976 to 2005, we projected mortality rates by neighborhood-level socio-economic position (i.e., low- or high-income groups) to 2020 in Hong Kong using Poisson age-period-cohort models with autoregressive priors.

Results
In the low-income group, age-standardized IHD mortality rates among women declined from 33.3 deaths in 1976–1980 to 19.7 per …

Locus Coeruleus And Hippocampal Tyrosine Hydroxylase Levels In A Pressure-Overload Model Of Heart Disease, Luke A. Johnson

Undergraduate Honors Theses

Studies have indicated that approximately 30% of people with heart disease experience major depressive disorder (MDD). Despite strong clinical evidence of a link between the two diseases, the neurobiological processes involved in the relationship are poorly understood. A growing number of studies are revealing similar neuroanatomical and neurochemical abnormalities resulting from both depression and heart disease. The locus coeruleus (LC) is a group of neurons in the pons that synthesize and release norepinephrine, and that is known to play a significant role in depression pathobiology. For example, there is evidence that tyrosine hydroxylase (TH) is elevated in the LC in …

The Effect Of Statins On Testosterone In Men And Women, A Systematic Review And Meta-Analysis Of Randomized Controlled Trials, Mary Schooling, Shiu Lun Au Yeung, Guy Freeman, Benjamin J. Cowling

Publications and Research

Background
Statins are extensively used for cardiovascular disease prevention. Statins reduce mortality rates morethan other lipid-modulating drugs, although evidence from randomized controlled trials also suggests that statinsunexpectedly increase the risk of diabetes and improve immune function. Physiologically, statins would beexpected to lower androgens because statins inhibit production of the substrate for the local synthesis of androgens and statins’ pleiotropic effects are somewhat similar to the physiological effects of lowering testosterone, so we hypothesized that statins lower testosterone.

Methods
A meta-analysis of placebo-controlled randomized trials of statins to test the a priori hypothesis that statins lower testosterone. We searched the PubMed, …

Acute Aortic Valve Rupture From Infective Endocarditis After Transrectal Prostate Biopsy: A Call To Revise The Aha Guidelines For Prevention Of Infective Endocarditis, Julia Ansari, Gurkaran Singh Garcha, Henry Huang, Faisal G. Bakaeen, Salim S. Virani, Hani Jneid

Office of the Provost

We describe the case of a 63-year-old man with a known murmur who presented with a 4-month history of intermittent fever and a progressive reduction in energy level after a transrectal prostate biopsy (TRPB). He subsequently presented with acute heart failure secondary to aortic valve cusp rupture caused by endocarditis and underwent urgent aortic valve surgery. The 2008 American College of Cardiology/American Heart Association Guideline update on infective endocarditis has narrowed the use of antibiotic prophylaxis before most accepted dental procedures and continues to recommend against prophylaxis before genitourinary or gastrointestinal procedures. In contrast, the American Urological Association recommends the …

Loss Of Dystrophin Staining In Cardiomyocytes: A Novel Method For Detection Early Myocardial Infarction, Satwat Hashmi, Suhail Al-Salam

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most frequent diagnosis made in majority of sudden death cases subjected to clinical and medicolegal autopsies. When sudden death occurs at a very early stage of MI, traditional macroscopic examination, or histological stains cannot easily detect the myocardial changes. For this reason we propose a new method for detecting MI at an early stage. Murine model of MI was used to induce MI through permanent ligation of left anterior descending branch of left coronary artery. Five groups of C57B6/J mice were used for inducing MI, which includes 20 minutes, 30 minutes, one hour, four hours …

Cardiovascular Fitness Associated With Cognitive Performance In Heart Failure Patients Enrolled In Cardiac Rehabilitation, Sarah Garcia, Michael L. Alosco, Mary Beth Spitznagel, Ronald Cohen, Naftali Raz, Lawrence Sweet, Richard Josephson, Joel Hughes, Jim Rosneck, Morgan L. Oberle, John Gunstad

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Reduced cognitive function is common in persons with heart failure (HF). Cardiovascular fitness is a known contributor to cognitive function in many patient populations, but has only been linked to cognition based on estimates of fitness in HF. The current study examined the relationship between fitness as measured by metabolic equivalents (METs) from a standardized stress test and cognition in persons with HF, as well as the validity of office-based predictors of fitness in this population.

Methods

Forty-one HF patients enrolled in cardiac rehabilitation completed a standardized exercise stress test protocol, a brief neuropsychological battery, the 2-minute step …
