Beth Hands

Introduction: Systematic reviews suggest that a longer duration of breast-feeding is associated with a reduction in the risk of later overweight and obesity. Most studies examining breast-feeding in relation to adiposity have not used longitudinal analysis. In our study, we aimed to examine early infant feeding and adiposity risk in a longitudinal cohort from birth to young adulthood using new as well as published data. Methods: Data from the Western Australian Pregnancy Cohort (Raine) Study in Perth, W.A., Australia, were used to examine associations between breast-feeding and measures of adiposity at 1, 2, 3, 6, 8, 10, 14, 17, and …

Exploring Body Mass Index Changes In Left Ventricular Assist Device Patients, Raquel E. Thomas, Corrine Hanson, Glenda Woscyna, Brian D. Lowes Jun 2016

Exploring Body Mass Index Changes In Left Ventricular Assist Device Patients, Raquel E. Thomas, Corrine Hanson, Glenda Woscyna, Brian D. Lowes

The VAD Journal

Background: Current treatment options for end-stage heart failure, such as transplantation, can be limited by obesity guidelines. Mechanical devices such as Left Ventricular Assistive Devices (LVAD) can bridge heart failure patients to transplantation, however, after implantation; some patients may experience weight gain that precludes them from transplantation. Therefore, the objective of this study was to evaluate weight changes after the implantation of an LVAD.

Methods: A retrospective review of 130 patients receiving an LVAD were divided into two groups based on BMI at the time of implantation: obese (>30 kg/m2) and non-obese (/m2). Patients were …

Health Policy and Management Faculty Publications

Abstract

Background

We assessed the predictive accuracy of an empirically-derived score (weight loss, insulin resistance, and glycemic control: “WIG”) to predict patients who will be successful in reducing diabetes mellitus (DM) medication use with weight loss.

Methods

Case records of 121 overweight and obese patients with DM at two outpatient weight management centers were analyzed.

Results

Mean period of follow-up was 12.5 ± 3.5 months. To derive the “WIG” scoring algorithm, one point each was assigned to “W” (loss of 5% of initial body weight within the first 3 months of attempting weight loss), “I” (triglyceride [TGL]/highdensity lipoprotein ratio >3 …


Piloting A Screening Tool For Eating And Eating-Related Behavior, Michael N. Reynolds Jun 2016

Piloting A Screening Tool For Eating And Eating-Related Behavior, Michael N. Reynolds

Dissertations

Obesity is a common medical condition associated with negative health and social outcomes. Obesity has a primary malleable behavioral cause, eating more calories than are metabolized. While metabolic rate is malleable with exercise, eating can more quickly add calories than exercising can subtract them. In the past, behavioral weight-loss treatment studies relied on multi-component package interventions that have shown reliable patterns of participant weight-loss during treatment and weight-regain in follow-up. Those findings could be conceptualized as an ABA withdrawal design, eating behavior returns to baseline after the prosthetic contingencies of the treatment study are withdrawn. We must develop ways to …

This is the first study in Egypt to determine possible relationships of these parameters. Background: ApoB-100 is a large, amphipathic glycoprotein playing a central role in human lipoprotein metabolism and is required for very low-density lipoprotein production in the liver. ApoB-100 is also the ligand for low-density lipoprotein-receptor-mediated endocytosis of low-density lipoprotein particles. There are several known ApoB-100 polymorphisms that …


Treatment Of Obesity: Weight Loss And Bariatric Surgery, Bruce M. Wolfe, Elizaveta Walker, Robert H. Eckel May 2016

Treatment Of Obesity: Weight Loss And Bariatric Surgery, Bruce M. Wolfe, Elizaveta Walker, Robert H. Eckel

Elizaveta Walker

This review focuses on the mechanisms underlying, and indications for, bariatric surgery in the reduction of cardiovascular disease (CVD), as well as other expected benefits of this intervention. The fundamental basis for bariatric surgery for the purpose of accomplishing weight loss is the determination that severe obesity is a disease associated with multiple adverse effects on health, which can be reversed or improved by successful weight loss in patients who have been unable to sustain weight loss by nonsurgical means. An explanation of possible indications for weight loss surgery as well as specific bariatric surgical procedures is presented, along with …

A Link Between Paediatric Asthma And Obesity: Are They Caused By The Same Environmental Conditions?, Phylicia Gonsalves

Electronic Thesis and Dissertation Repository

The highly associated paediatric conditions of asthma and overweight have seen dramatic increases over the past few decades. This thesis explored air pollution exposure as a potential underlying mechanism of co-morbid asthma and overweight among adolescents aged 12 to 18 years. Data from the Canadian Community Health Survey were merged with a database containing estimates of air pollution as assessed by particulate matter ≤ 2.5 microns (PM2.5) concentrations at the postal code centroid in southwestern Ontario. Logistic regression was used to conduct the analysis. Adolescents were more likely to be overweight as PM2.5 concentrations increased. There was …

Doctoral Projects

Often, being away from home for the first time, coupled with limited knowledge regarding healthy eating behaviors, leads to poor food choices and an increased risk of obesity among college-aged young adults. These college students are prone to high-calorie diets and limited physical activity, putting them at risk for obesity, a physiologically, psychologically, and financially costly epidemic in the United States. College students use their cellular phones over eight and a half hours a day and cell phones are their primary means of information consumption outside of the classroom, suggesting that the phones would be a useful tool to provide …

Evaluating Dietary Quality And Taste Preferences With A Simple Liking Survey: Application To Studying Individuals With Morbid Obesity, Marina L. Zoghbi

Honors Scholar Theses

Feasible ways are needed to screen for dietary behaviors and taste preferences in clinical settings. We examined the internal validity and reliability of a brief survey to assess food preferences and dietary behaviors among morbidly obese individuals considering bariatric surgery. Survey-reported liking is a proxy for dietary intake, correlating with reported food intake and biomarkers of nutritional status (Sharafi et al, 2015) and linking taste genetics with diet and health (Pallister et al, 2015). Methods –Enrolled were 138 morbidly obese patients awaiting bariatric surgery, who completed a 100-item liking survey of foods/beverages, physical/sedentary activities, and pleasurable/unpleasurable experiences. They were oriented …


The Relationships Between The Home Food Environment And Weight Status Among Children And Adolescents, Ages 6-17 Years, Martha J. Nepper May 2016

The Relationships Between The Home Food Environment And Weight Status Among Children And Adolescents, Ages 6-17 Years, Martha J. Nepper

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

The home food environment is an important setting in regard to a child’s dietary intake and the development of obesity, since 65% to 72% of daily calories are consumed in the home. Research is beginning to explore how the home food environment may influence children’s weight status. It is suggested that homes with healthy weight children are more likely to have healthier food options available and limit access to unhealthy foods. Prior research on the influence of the home food environment on children and adolescent’s weight status is not clear, as some researchers have found that the home food environment …

Increased uric acid levels have been implicated in the pathogenesis of metabolic syndrome. To examine the mechanisms by which this occurs, we hypothesized that an increase in heme oxygenase 1, a potent antioxidant gene, will decrease uric acid levels and adipocyte dysfunction via suppression of ROS and xanthine oxidase (XO) levels.We examined the effect of uric acid on adipogenesis in human mesenchymal stem cells (MSCs) in the presence and absence of cobalt protoporphyrin (CoPP), an HO-1 inducer, and tin mesoporphyrin (SnMP), an HO activity inhibitor. Uric acid increased adipogenesis by increasing NADPH oxidase expression and elevation in the adipogenesis markers …

Nader G. Abraham

Background Oxidative stress underlies the etiopathogenesis of nonalcoholic fatty liver disease (NAFLD), obesity and cardiovascular disease (CVD). Heme Oxygenase-1 (HO-1) is a potent endogenous antioxidant gene that plays a key role in decreasing oxidative stress. Sirtuin1 (SIRT1) belongs to the family of NAD-dependent de-acyetylases and is modulated by cellular redox. Hypothesis We hypothesize that fructose-induced obesity creates an inflammatory and oxidative environment conducive to the development of NAFLD and metabolic syndrome. The aim of this study is to determine whether HO-1 acts through SIRT1 to form a functional module within hepatocytes to attenuate steatohepatitis, hepatic fibrosis and cardiovascular dysfunction. Methods …

Na/K-Atpase Amplification Of Oxidant Stress; A Universal But Unrecognized Clinical Target?, Zijian Xie, Phd, Joseph I. Shapiro, Md Apr 2016

Na/K-Atpase Amplification Of Oxidant Stress; A Universal But Unrecognized Clinical Target?, Zijian Xie, Phd, Joseph I. Shapiro, Md

Joseph I Shapiro MD

The Na/K-ATPase has a signaling function which appears to be separate from its ion pumping function. This signaling function refers to the transduction of conformational changes in the Na/K-ATPase alpha1 subunit into activating Src’s tyrosine kinase activity, triggering a cascade which generates reactive oxygen species (ROS), modulates other signaling pathways, and causes many physiological and pathophysiological effects. We have recently observed that ROS themselves as well as cardiotonic steroids can actually initiate the signal by directly inducing conformational changes in alpha1. It therefore appears that the Na/K-ATPase signal cascade can serve as a feed forward amplification for ROS with circulating …
