Faculty, Staff and Students Publications

Obesity is associated with chronic inflammation in the central nervous system (CNS), and neuroinflammation has been shown to have detrimental effects on mood and cognition. The growth hormone secretagogue receptor (GHSR), the biologically relevant receptor of the orexigenic hormone ghrelin, is primarily expressed in the brain. Our previous study showed that neuronal GHSR deletion prevents high-fat diet-induced obesity (DIO). Here, we investigated the effect of neuronal GHSR deletion on emotional and cognitive functions in DIO. The neuron-specific GHSR-deficient mice exhibited reduced depression and improved spatial memory compared to littermate controls under DIO. We further examined the cortex and hippocampus, the …

Children’s Nutrition Research Center Staff Publications

Background: Smith Magenis Syndrome (SMS) is a rare genetic disorder caused by RAI1 haploinsufficiency. Obesity in people with SMS is believed partially due to dysfunction of the proximal melanocortin 4 receptor (MC4R) pathway. We therefore studied effects of treatment with the MC4R agonist setmelanotide on obesity and hunger, as well as metabolic, cardiac and safety, in individuals with SMS.

Methods: People with SMS received once-daily setmelanotide injections, with the dose titrated bi-weekly to a maximum of 3 mg over ∼1 month; and a full-dose treatment duration of 3mo. The primary outcome was percent change in body weight. Secondary outcomes included …

The Impact Of Obesity-Associated Glycine Deficiency On The Elimination Of Endogenous And Exogenous Metabolites Via The Glycine Conjugation Pathway, Hong Chang Tan, Jean W Hsu, E Shyong Tai, Shaji Chacko, Jean-Paul Kovalik, Farook Jahoor

Faculty, Staff and Students Publications

BACKGROUND: Glycine is an integral component of the human detoxification system as it reacts with potentially toxic exogenous and endogenously produced compounds and metabolites via the glycine conjugation pathway for urinary excretion. Because individuals with obesity have reduced glycine availability, this detoxification pathway may be compromised. However, it should be restored after bariatric surgery because of increased glycine production.

OBJECTIVE: To examine the impact of obesity-associated glycine deficiency on the glycine conjugation pathway. We hypothesize that the synthesis rates of acylglycines from endogenous and exogenous sources are significantly reduced in individuals with obesity but increase after bariatric surgery.

METHODS: We …

Fetal Abdominal Obesity In Women With One Value Abnormality On Diagnostic Test For Gestational Diabetes Mellitus, Wonjin Kim, Soo Kyung Park, Yoo Lee Kim

The Brown Foundation: Institute of Molecular Medicine

Previous studies have shown that fetal abdominal obesity (FAO) was already observed at the time of gestational diabetes mellitus (GDM) diagnosis and persisted until delivery despite management in older and/or obese women. In this study, we investigated whether fetuses of women with milder hyperglycemia than GDM have accelerated abdominal growth, leading to adverse pregnancy outcomes. We retrospectively reviewed the medical records of 7,569 singleton pregnant women who were universally screened using a 50-g glucose challenge test (GCT) and underwent a 3-h 100-g oral glucose tolerance test (OGTT) if GCT result was ≥140mg/dL.

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a heterogenous clinical syndrome defined by hyperandrogenism and irregular menses. In adult women with PCOS, discrete metabolic and reproductive subgroups have been identified. We hypothesize that distinct phenotypes can be distinguished between adolescent girls who are lean (LN-G) and girls with obesity (OB-G) at the time of PCOS diagnosis.

METHODS: Data were extracted from the CALICO multisite PCOS database. Clinical data collected at the time of diagnosis were available in 354 patients (81% with obesity) from 7 academic centers. Patients with body mass index (BMI) < 85th percentile for age and sex were characterized as lean (LN-G) and those with BMI percentile ≥ 95th percentile as obese (OB-G). We compared metabolic and reproductive phenotypes in LN-G and OB-G.

RESULTS: Reproductive phenotypes differed between the groups, with LN-G …

Introduction: Longitudinal effect of diet-induced obesity on bone is uncertain. Prior work showed both no effect and a decrement in bone density or quality when obesity begins prior to skeletal maturity. We aimed to quantify long-term effects of obesity on bone and bone marrow adipose tissue (BMAT) in adulthood.

Methods: Skeletally mature, female C57BL/6 mice (n = 70) aged 12 weeks were randomly allocated to low-fat diet (LFD; 10% kcal fat; n = 30) or high-fat diet (HFD; 60% kcal fat; n = 30), with analyses at 12, 15, 18, and 24 weeks (n = 10/group). Tibial microarchitecture was analyzed …

The Role Of Uric Acid In Metabolic Abnormalities Of Obesity, Andrew P. Giromini

Graduate Theses, Dissertations, and Problem Reports (ETD)

Uric acid (UA) is the single most tightly associated metabolite for obesity and type 2 diabetes. While the field varies on whether UA is causative or correlative of the metabolic dysfunction allied to obesity, these studies use different diets and animal models to make these claims. It is the goal of this dissertation to compare different diets commonly used in this research to delve deeper into the data and determine which diets induce elevated circulating UA levels as well as which diets also induce metabolic dysfunction. Early chapters of this dissertation examine the comparison of high fructose consumption, both in …

Adipose Tissue Lymphocytes And Obesity, Feng Gao, Benjamin Litchfield, Huaizhu Wu

Faculty, Staff and Students Publications

Obesity is associated with chronic inflammation in adipose tissue (AT), mainly evidenced by infiltration and phenotypic changes of various types of immune cells. Macrophages are the major innate immune cells and represent the predominant immune cell population within AT. Lymphocytes, including T cells and B cells, are adaptive immune cells and constitute another important immune cell population in AT. In obesity, CD8+ effector memory T cells, CD4+ Th1 cells, and B2 cells are increased in AT and promote AT inflammation, while regulatory T cells and Th2 cells, which usually function as immune regulatory or type 2 inflammatory cells, are reduced …

A Structure-Function Analysis Of Hepatocyte Arginase 2 Reveals Mitochondrial Ureahydrolysis As A Determinant Of Glucose Oxidation, Yiming Zhang, Jiameng Sun, Henry D Wasserman, Joshua A Adams, Cassandra B Higgins, Shannon C Kelly, Louise Lantier, Brian J Debosch

2020-Current year OA Pubs

BACKGROUND & AIMS: Restoring hepatic and peripheral insulin sensitivity is critical to prevent or reverse metabolic syndrome and type 2 diabetes. Glucose homeostasis comprises in part the complex regulation of hepatic glucose production and insulin-mediated glucose uptake and oxidation in peripheral tissues. We previously identified hepatocyte arginase 2 (Arg2) as an inducible ureahydrolase that improves glucose homeostasis and enhances glucose oxidation in multiple obese, insulin-resistant models. We therefore examined structure-function determinants through which hepatocyte Arg2 governs systemic insulin action and glucose oxidation.

METHODS: To do this, we generated mice expressing wild-type murine Arg2, enzymatically inactive Arg2 (Arg2

RESULTS: We show …

P53r245w Mutation Fuels Cancer Initiation And Metastases In Nash-Driven Liver Tumorigenesis, Denada Dibra, Mihai Gagea, Yuan Qi, Gilda P Chau, Xiaoping Su, Guillermina Lozano

Faculty, Staff and Student Publications

Obesity is a significant global health concern. Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NASH) are common risk factors for hepatocellular carcinoma (HCC) and are closely associated with metabolic comorbidities, including obesity and diabetes. The TP53 tumor suppressor is the most frequently mutated gene in liver cancers, with half of these alterations being missense mutations. These mutations produce highly abundant proteins in cancer cells which have both inhibitory effects on wildtype (WT) p53, and gain-of-function (GOF) activities that contribute to tumor progression. A Western diet increases p53 activity in the liver. To elucidate the functional consequences of Trp53 mutations in …

Glp1 Receptor Agonists-Effects Beyond Obesity And Diabetes, Sydney S Wilbon, Mikhail G Kolonin

Faculty, Staff and Student Publications

Glucagon-like peptide-1 receptor agonists (GLP1RA) have been transformative for patients and clinicians in treating type-2 diabetes and obesity. Drugs of this class, the bioavailability of which is continuously improving, enable weight loss and control blood glucose with minimal unwanted side effects. Since adopting GLP1RA for treating metabolic diseases, animal and clinical studies have revealed their beneficial effects on several other pathologies, including cardiovascular diseases, neurodegeneration, kidney disease, and cancer. A notable commonality between these diseases is their association with older age. Clinical trials and preclinical data suggest that GLP1RA may improve outcomes in these aging-related diseases. Some of the benefits …

Strategies To Reduce Chronic Disease: Adding Role To Community Health Workers, Ingrid J. Renwanz Dnp, Pmhfnp-Bc/Aprn, Msn, Rnc

Doctor of Nursing Practice (DNP) Projects

Background: Underserved, rural, immigrant, low-income Latinx communities need to strengthen healthcare access to improve their quality of life (Capitman et al., 2009; McCartney et al., 2019; Save the Children [STC] Organization, 2021). Non-communicable chronic disease of physical and behavioral origin is the leading cause of morbidity for adults and children in Latinx communities (Campbell et al., 2020). Estimates of greater than 30% of the Latinx populations within the United States have these health needs, with projections to reach 28% of the U.S. population by 2060 (Eghaneyan & Murphy, 2019; Ortega et al., 2018).

Faculty, Staff and Student Publications

Background: The relationship between obesity and non-Hodgkin's lymphoma (NHL) was controversial, which may be due to the crudeness definition of obesity based on body mass index (BMI). As obesity and metabolic abnormalities often coexist, we aimed to explore whether the classification of obesity based on metabolic status can help to evaluate the real impact of obesity on the readmission of NHL.

Methods: In this retrospective cohort study, utilizing the 2018 Nationwide Readmissions Database, we identified NHL-related index hospitalizations and followed them for non-elective readmission. The patients with NHL were classified as metabolically healthy non-obese (MHNO) and obese (MHO) and metabolically …

A Literature Review On Thermogenesis As A Prospective Obesity Treatment, Kellyn Sheppard

Senior Honors Theses

The disease of obesity has quickly escalated from an epidemic to a worldwide pandemic in the last few decades, and viable treatment methods are being investigated with urgency. One such treatment method is increased induction of the thermogenesis pathway that is active in brown adipose tissue. This pathway is typically activated in mammals when they are exposed to cold temperatures for extended periods of time but can also be induced exogenously. Thermogenesis is a metabolically inefficient process that occurs in the mitochondria of a cell, meaning it uses substrate energy without generating ATP. The inefficiency of this process allows excess …

Implementing Community Health Workers To Improve The Management Of Chronic Non-Communicable Diseases In Children, Julia L. Newell

Doctor of Nursing Practice (DNP) Projects

Background: Childhood obesity, asthma, and untreated mental health conditions are three examples of chronic non-communicable diseases (CNDs) that pose a host of negative consequences later in life. Minority children from low-income families, especially those with environmental disadvantages, face additional risk factors for the development of these diseases. Community health workers (CHWs) are in a unique position to help address these negative health externalities by being attuned with the linguistic, cultural, and socioemotional needs of members of their communities. Research has demonstrated success in CHW-led interventions curtailing the negative impacts associated with these diseases in low-income, minority communities.

Methods: A literature …

Chronic Stressors, Obesity Pathogenesis, And The Moderating Effect Of Internalized Weight Stigma; A Quantitative, Illinois Study, Karyn Byrne

Dissertations

The obesity epidemic is a ‘wicked’ problem with a complex web of determinants and outcomes. While generally higher for minoritized populations, prevalence rates manifest in surprising, nonlinear patterns. There is no consensus regarding treatment protocols or mitigation efforts, except that current efforts remain largely ineffective. Much research evidence that a profusion of determinants of health support obesity pathogenesis through various physiological processes and mechanisms, including the allostatic load, mitochondria functioning, the gut microbiome, and epigenetics. Intervening to support markers of the allostatic load (immunity, inflammation, and metabolic health) may provide a more effective treatment outcomes than traditional approaches, which tend …

Implications Of California State Standards In Relation To Disordered Eating For School Aged Children, Jessica De Mott

Capstone Projects and Master's Theses

Food is a part of people’s lives, even when it is not acknowledged. It is distinctly tied to various cultures, ethnicities, and religions; with elements of restriction and gluttony abundant. Then, there is the complication of modern nutrition and health education that is taught in American, and more specifically in Californian schools. But, the education received on this issue has failed some students. Many school aged children reported that they experienced disordered eating, and learning content has further exacerbated this issue. This senior capstone research will examine the implications of California State Standards in relation to disordered eating for school …

Design, Analysis, And Interpretation Of Treatment Response Heterogeneity In Personalized Nutrition And Obesity Treatment Research, Roger S Zoh, Bridget H Esteves, Xiaoxin Yu, Amanda J Fairchild, Ana I Vazquez, Andrew G Chapple, Andrew W Brown, Brandon George, Derek Gordon, Douglas Landsittel, Gary L Gadbury, Greg Pavela, Gustavo De Los Campos, Luis M Mestre, David B Allison

Children’s Nutrition Research Center Staff Publications

It is increasingly assumed that there is no one-size-fits-all approach to dietary recommendations for the management and treatment of chronic diseases such as obesity. This phenomenon that not all individuals respond uniformly to a given treatment has become an area of research interest given the rise of personalized and precision medicine. To conduct, interpret, and disseminate this research rigorously and with scientific accuracy, however, requires an understanding of treatment response heterogeneity. Here, we define treatment response heterogeneity as it relates to clinical trials, provide statistical guidance for measuring treatment response heterogeneity, and highlight study designs that can quantify treatment response …
