Sarcopenic Obesity, Pathogenesis, And Treatment With A Focus On Exercise And Protein Intake, Yasemin Karaağaç

Journal of Mind and Medical Sciences

Sarcopenic obesity involves the co-occurrence of sarcopenia and obesity, yields more health risks than either condition alone, thus requiring prevention and treatment for healthy aging. In this review, the literature on the diagnosis of sarcopenic obesity, the mechanisms of its pathogenesis and treatment with emphasis on exercise and dietary protein were revised. Changes in body composition and sex hormones with age, myocellular mechanisms, inflammation, oxidative stress, physical inactivity, and insufficient protein intake are the main factors associated with the pathogenesis of sarcopenic obesity. Treatment targets weight loss while preserving muscle mass and function. Promising approaches involve high-protein and low-calorie diets …

Makara Journal of Health Research

Background: This study aimed to investigate the risk factors and status of fast-food consumption among students in Bangladesh.

Methods: This cross-sectional study was conducted from March to November 2020. A total of 654 samples were collected from several schools, colleges, and universities during this study period.

Results: About 60.1% and 39.9% of the students were male and female, respectively. Of the students, 53.1% considered fast food as unhealthy (p < 0.001), but only 47.7% were leading a sedentary lifestyle. A significant outcome of overweight and pre-obesity was observed for student institutions, consumption frequency, daily fast-food consumption, and sedentary lifestyle (p < 0.001). In addition, positive association was observed for fast-food consumption more than three times and less than three times per week (OR and 95% CI: 11.13 [7.52–16.47], p < 0.001), higher social class and lower class (OR and 95% CI: 2.18 [1.31–3.62], p = 0.003), fast food preference and other foods (OR and 95% CI: 1.55 [1.11–2.15], p = 0.009), and sedentary and heavily active lifestyle (OR …

Nursing Faculty Publications

With the prevalence of obesity in adolescents, and its long-term influence on their overall health, there is a large body of research exploring better ways to reduce the rate of obesity. A traditional way of maintaining an adequate body mass index (BMI), calculated by measuring the weight and height of an individual, is no longer enough, and we are in need of a better health care tool. Therefore, the current research proposes an easier method that offers instant and real-time feedback to the users from the data collected from the motion sensors of a smartphone. The study utilized the mHealth …

Adipose-Specific Pparα Knockout Mice Have Increased Lipogenesis By Pask–Srebp1 Signaling And A Polarity Shift To Inflammatory Macrophages In White Adipose Tissue, Terry D. Hinds, Jr., Zachary A. Kipp, Mei Xu, Frederique B. Yiannikouris, Andrew J. Morris, Donald F. Stec, Walter Wahli, David E. Stec

Pharmacology and Nutritional Sciences Faculty Publications

The nuclear receptor PPARα is associated with reducing adiposity, especially in the liver, where it transactivates genes for β-oxidation. Contrarily, the function of PPARα in extrahepatic tissues is less known. Therefore, we established the first adipose-specific PPARα knockout (Ppara^FatKO) mice to determine the signaling position of PPARα in adipose tissue expansion that occurs during the development of obesity. To assess the function of PPARα in adiposity, female and male mice were placed on a high-fat diet (HFD) or normal chow for 30 weeks. Only the male Ppara^FatKO animals had significantly more adiposity in the inguinal white …

Fucoxanthin: A Review Of Potential Benefits Relative To Human Health, Michael R. White

Masters Theses, 2020-current

Fucoxanthin is a carotenoid sourced and extracted mainly from dark orange and brown seaweeds found in the pacific ocean, such as the wakame algae. The allenic bonds and unique oxygen groups give fucoxanthin its unique structure and are thought to be part of the reason fucoxanthin has unique physiological functions. Fucoxanthin has potentially numerous effects on the physiology of human health, ranging from skin health to metabolic health, which have been demonstrated in animal model research. The goal of this review is to examine current literature to discuss fucoxanthin’s potential application as a nutraceutical, treatment for obesity, type 2 diabetes, …

Optimisation Of Vitamin D Status For Enhanced Immuno-Protection Against Covid-19, Daniel Mccartney, Declan G. Byrne

Articles

Abstract

Background

Vitamin D deficiency (serum 25(OH)D<50nmol/l) is common in Ireland, particularly amongst older adults, hospital inpatients and nursing home residents. Vitamin D deficiency is associated with increased risk of acute viral respiratory infection and community acquired pneumonia, with several molecular mechanisms proposed to explain this association. Vitamin D supplementation has also been shown to reduce the risk of respiratory infection.

Vitamin D and Covid-19

Correction of vitamin D deficiency is thought to suppress CD26, a putative adhesion molecule for Covid-19 host cell invasion. Vitamin D may also attenuate interferon gamma (IFNγ) and interleukin-6 (IL-6) inflammatory responses, both potent predictors of poorer outcome in critically-ill ventilated patients including those with Covid-19.

Vitamin D Requirements

Irish adults require 25-30μg/d of vitamin D3, an intake not achievable by diet alone, to reliably maintain serum 25(OH)D levels >50nmol/l. Supplementation with doses up to 100μg/d has been shown to be safe for adults, and many agencies and expert …

Food for Health: Publications

Childhood obesity is a serious public health problem worldwide. Perturbations in the gut microbiota composition have been associated with the development of obesity in both children and adults. Probiotics, on the other hand, are proven to restore the composition of the gut microbiome which helps reduce the development of obesity. However, data on the effect of probiotics on gut microbiota and its association with childhood obesity is limited. This study aims to determine the effect of probiotics supplement intervention on gut microbiota profiles in obese and normal-weight children. A total of 37 children, 17 normal weight, and 20 overweight school …

Contributing Factors To Diabetic Brain Injury And Cognitive Decline, Nirmal Verma, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

The link of diabetes with co-occurring disorders in the brain involves complex and multifactorial pathways. Genetically engineered rodents that express familial Alzheimer's disease-associated mutant forms of amyloid precursor protein and presenilin 1 (PSEN1) genes provided invaluable insights into the mechanisms and consequences of amyloid deposition in the brain. Adding diabetes factors (obesity, insulin impairment) to these animal models to predict success in translation to clinic have proven useful at some extent only. Here, we focus on contributing factors to diabetic brain injury with the aim of identifying appropriate animal models that can be used to mechanistically dissect the …

Rising Rural Body-Mass Index Is The Main Driver Of The Global Obesity Epidemic In Adults, Con Burns, Tara Coppinger, Janette Walton, Et Al

Publications

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to …

NYMC Faculty Publications

OBJECTIVE: To determine if there is an increased maternal or neonatal morbidity in overweight and obese patients with a false positive glucose challenge test (GCT). METHODS: Patients with a body mass index (BMI) >/=25.0 at registration were included in this prospective 36-month study. The study cohort consisted of patients with a false positive (FP) GCT, with two comparison cohorts: those with a (1) screen negative (SN) GCT result and (2) true positive (TP) GCT result. Risks were reported as odd ratios with 95% confidence intervals, with a P/=4000 g in the FP cohort, but this fell short of reaching statistical …

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 …

Thrombospondin1 Deficiency Attenuates Obesity-Associated Microvascular Complications In Apoe-/- Mice, Hasiyeti Maimaitiyiming, Kate Clemons, Qi Zhou, Heather Norman, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

Obesity is associated with insulin resistance and the increased development of vascular complications. Previously, we have demonstrated that thrombospondin1 (TSP1) regulates macrophage function and contributes to obesity associated inflammation and insulin resistance. However, the role of TSP1 in the development of obesity associated vascular complications is not clear. Therefore, in the current study, we investigated whether TSP1 deficiency protects mice from obesity associated micro as well as macro-vascular complications in ApoE-/- mice. In this study, male ApoE-/- mice and ApoE-/-TSP1-/- mice were fed with a low-fat (LF) or a high-fat (HF) diet for 16 weeks. We found that body weight …

Cd47 Deficiency Protects Mice From Diet-Induced Obesity And Improves Whole Body Glucose Tolerance And Insulin Sensitivity, Hasiyeti Maimaitiyiming, Heather Norman, Qi Zhou, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

CD47 is a transmembrane protein with several functions including self-recognition, immune cell communication, and cell signaling. Although it has been extensively studied in cancer and ischemia, CD47 function in obesity has never been explored. In this study, we utilized CD47 deficient mice in a high-fat diet induced obesity model to study for the first time whether CD47 plays a role in the development of obesity and metabolic complications. Male CD47 deficient and wild type (WT) control mice were fed with either low fat (LF) or high fat (HF) diets for 16 weeks. Interestingly, we found that CD47 deficient mice were …

Cardioprotection By Controlling Hyperamylinemia In A "Humanized" Diabetic Rat Model, Sanda Despa, Savita Sharma, Todd R. Harris, Hua Dong, Ning Li, Nipavan Chiamvimonvat, Heinrich Taegtmeyer, Kenneth B. Margulies, Bruce D. Hammock, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: Chronic hypersecretion of the pancreatic hormone amylin is common in humans with obesity or prediabetic insulin resistance and induces amylin aggregation and proteotoxicity in the pancreas. We recently showed that hyperamylinemia also affects the cardiovascular system. Here, we investigated whether amylin aggregates interact directly with cardiac myocytes and whether controlling hyperamylinemia protects the heart.

METHODS AND RESULTS: By Western blot, we found abundant amylin aggregates in lysates of cardiac myocytes from obese patients, but not in controls. Aggregated amylin was elevated in failing hearts, suggesting a role in myocyte injury. Using rats overexpressing human amylin in the pancreas (HIP …

Research outputs 2014 to 2021

Despite the increasing use of dietary patterns (DP) to study diet and health outcomes, relatively few studies have examined the reliability of DP using different dietary assessment methods. Reduced-rank regression (RRR) is an emerging statistical method that incorporates a priori information to characterise DP related to specific outcomes of interest. The aim of the present study was to compare DP identified using the RRR method in a FFQ with those in a 3 d food record (FR). Participants were 783 adolescents from the Western Australian Pregnancy (Raine) Cohort Study who completed both a FFQ and FR at 14 years of …

Vitamin D Levels And Risk Of Dyslipidemia Among Us Children With Diabetes And Obesity, Elsina E. Hagan

Masters Theses 1911 - February 2014

Dyslipidemia is increasing among U.S. children, and the prevalence is highest among children with diabetes and obesity. Recently, vitamin D deficiency has been suggested as a possible dietary risk factor for dyslipidemia. Despite the high prevalence of vitamin D deficiency amongst children, virtually no studies have evaluated the association between vitamin D and dyslipidemia among children. We evaluated the vitamin D and dyslipidemia relationship among 240 children and adolescents aged 2 through 21 years who were outpatients of a pediatric endocrinology unit at a large tertiary care facility in Western Massachusetts from April 2008 to April 2010. Eligible children were …

Economic Efficiency And Consumer Choice Theory In Nutritional Labeling, Michael Mccann

Law Faculty Scholarship

As more Americans consume fast food each year, more Americans are contracting serious diseases related to obesity. Considering that obesity ranks second behind tobacco use as the largest contributor to mortality rates in the United States, and also that it gives rise to greater publicly funded health care expenses than does tobacco, this phenomenon begs the obvious question: To what extent does the growing consumption of fast food contribute to the obesity epidemic and the incidence of disease? If the answer indicates a meaningful contribution, a natural follow-up question then emerges: In a sensible legal system, what instruments would best …
