Household air pollution from biomass cookstoves is estimated to be responsible for more than two and a half million premature deaths annually, primarily in low and middle‐income countries where cardiometabolic disorders, such as Type II Diabetes, are increasing. Growing evidence supports a link between ambient air pollution and diabetes, but evidence for household air pollution is limited. This cross‐sectional study of 142 women (72 with traditional stoves and 70 with cleaner‐burning Justa stoves) in rural Honduras evaluated the association of exposure to household air pollution (stove type, 24‐hour average kitchen and personal fine particulate matter [PM2.5] mass and black carbon) …

Pituitary Tuberculoma, Amir Humza Sohail, Umar Farooq Bhatti, Najmul Islam

Section of Diabetes, Endocrinology and Metabolism

Tuberculosis rarely involves the hypothalamo-pituitary region and constitutes only 1% of the lesions involving the sellar and/or suprasellar region. Coleman and Meredith first reported pituitary tuberculosis in 1940, and only a handful of cases have been reported ever since. It may manifest as a chiasmal syndrome due to compression of the optic chiasm or as hypopituitarism due to pituitary destruction. It has a characteristic radiological appearance and can mimic a pituitary adenoma. Diagnostic procedures, such as trans-sphenoidal biopsy, are crucial for accurate diagnosis. We report a case of a 32-year male, who presented with complaints of headache and decreased visual …

The Effects Of Alcohol On Plasma Lipid Mediators Of Inflammation Resolution In Patients With Type 2 Diabetes Mellitus, Anne Barden, Sujata Shinde, Michael Phillips, Lawrence Beilin, Emilie Mas, Jonathan M. Hodgson, Ian Puddey, Trevor A. Mori

Research outputs 2014 to 2021

Background: Type 2 diabetes mellitus is characterized by peripheral insulin resistance and low-grade systemic inflammation. Inflammation resolution is recognised as an important process driven by specialised pro-resolving mediators of inflammation (SPMs) and has the potential to moderate chronic inflammation. Alcohol has the potential to affect synthesis of SPMs by altering key enzymes involved in SPM synthesis and may influence ongoing inflammation associated with Type 2 diabetes mellitus.

Aims: (i) To examine the effects of alcohol consumed as red wine on plasma SPM in men and women with Type 2 diabetes in a randomised controlled trial and (ii) compare baseline plasma …

Maternal Betaine Supplementation Affects Fetal Growth And Lipid Metabolism Of Highfat Fed Mice In A Temporal-Specific Manner, Yaelle Joselit, Khatia Nanobashvili, Chauntelle Jack-Roberts, Esther Greenwald, Olga V. Malysheva, Marie A. Caudill, Anjana Saxena, Xinyin Jang

Publications and Research

Background/objectives: Maternal obesity increases the risk of gestational diabetes mellitus (GDM), which results in fetal overgrowth and long-lasting metabolic dysfunctioning in the offspring. Previous studies show that maternal choline supplementation normalizes fetal growth and adiposity of progeny from obese mice. This study examines whether supplementation of betaine, a choline derivative, has positive effects on fetal metabolic outcomes in mouse progeny exposed to maternal obesity and GDM.

Methods: C57BL/6J mice were fed either a high-fat (HF) diet or a control (normal-fat, NF) diet and received either 1% betaine (BS) or control untreated (BC) drinking water 4–6 weeks before timed-mating and throughout …

Department of Family & Community Medicine Faculty Papers

BACKGROUND: Type 2 diabetes presents a major morbidity and mortality burden in the United States. Diabetes self-management education (DSME) is an intervention associated with improved hemoglobin A1c(HbA1c) and quality of life(QOL), and is recommended for all individuals with type 2 diabetes. African-Americans have disproportionate type 2 diabetes morbidity and mortality, yet no prior meta-analyses have examined DSME outcomes exclusively in this population. This systematic review and meta-analysis examined the impact of DSME on HbA1c and QOL in African-Americans compared to usual care.

METHODS: Randomized controlled trials, cluster-randomized trials, and quasi-experimental interventions were included. 352 citations were retrieved; 279 abstracts were …

Surgery Faculty Publications

AIMS: Type 2 diabetes is associated with endothelial dysfunction leading to cardiovascular disease. CD34+ endothelial Progenitor Cells (EPCs) are responsible for endothelial repair and neo-angiogenesis and can be used as a cardiovascular disease risk biomarker. This study investigated whether the addition of saxagliptin, a DPP-IV inhibitor, to metformin, may reduce cardiovascular disease risk in addition to improving glycemic control in Type 2 diabetes patients.

METHODS: In 12 week, double-blind, randomized placebo-controlled trial, 42 subjects already taking metformin 1-2 grams/day were randomized to placebo or saxagliptin 5 mg. Subjects aged 40-70 years with diabetes for < 10 years, with no known cardiovascular disease, BMI 25-39.9, HbA1C 6-9% were included. We evaluated EPCs number, function, surface markers and gene expression, in addition to arterial stiffness, blood biochemistries, resting energy expenditure, and body composition parameters. A mixed model regression to examine saxagliptin vs placebo, accounting for within-subject autocorrelation, was done with SAS (p < 0.05).

RESULTS: Although there was no significant …

Obesity: Modern Medicine Vs. Lifestyle, Jenny Christianson

Physician Assistant Scholarly Project Papers

Obesity is a rising epidemic, and is one of the most common, costly and preventable health problems the world is experiencing today (Center for Disease Control and Prevention, [CDC], 2017). From this, it is important to establish an effective treatment plan that can be implemented across the nation for maximum patient benefit. Lifestyle changes such as diet and exercise are important to any health care plan and are equally necessary to reduce health risks. However, in certain patients, lifestyle changes are not enough due to the maladaptive biologic process in their brain. From this, additional treatment options need to be …

The Effect Of Cellular Dehydration On Glucose Regulation In Lean And Obese Females, Chunbo Yang

Graduate Theses and Dissertations

A chronically elevated vasopressin level has been associated with an impaired glucose regulation system in humans. A recent study in patients with diabetes suggested that low water intake is associated with impaired glucose regulation. The aim of this study was to examine the effect of hypertonic saline infusion on glucose regulation in healthy females. Thirty healthy, non-diabetic females performed a 2-h infusion followed by a 4-h oral glucose tolerance test (OGTT). Every subject participated in two trials separated by one month, in a counterbalanced order. Two trials were identical in the procedure, differing in the concentration of saline infusion, with …

Do Global Diets Affect The Rate Of Type 2 Diabetes?, Demetria Meyer

Honors Theses

The purpose of this study is to determine whether different global diets correlate with the increase in type 2 diabetes rates. Type 2 diabetes is the main diabetes type being looked at due to it being the one that can be maintained primarily by glycemic control, which is controlled by a good diet. Five different countries from different regions will be examined: Brazil, China, Micronesia, Nigeria, and the United States. The diets of these countries will be broken down into smaller pieces, like calories consumed each day and the percentage of macronutrients that make up the calories. Eleven food groups …

Markers Of Cardiometabolic Risk And Thyroid Dysfunction In U.S. Adolescents: Nhanes Iii, Jonathan Austin

Theses and Dissertations

The global prevalence of metabolic syndrome (MetS) and its associated components (high fasting glucose, waist circumference, blood pressure, triglycerides, and low HDL) have increased over the past few decades. In addition, abnormal thyroid hormone levels have been found to manifest in a cascade of metabolic dysfunction, which may be linked to MetS in youth. PURPOSE: The purpose of the study is to investigate the association between MetS, its components, and markers of thyroid function in a nationally-representative sample of adolescents. METHODS: The National Health and Nutrition Examination Survey III (1988-1994) collected data on the components of metabolic syndrome and thyroid …

Disparities In Diabetes Rates And Quality Of Care Within Immigrants In The Usa, Anyun Chatterjee, Martin Blanco, George Gray

GW Research Days 2016 - 2020

Immigrants to the USA present an interesting opportunity to test the classical public health question of the impact of place on a health outcome. Diabetes is a prevalent disease in the USA which is slated to rise in rate in the future. Currently, 9.4% of the country is diabetic, and another 28% of the country is prediabetic. We posed the question - is this impact felt disproportionately by immigrants as they live in the US for a decade or more? Our preliminary literature search indicated that this has not been studied extensively, although the impact of American fast food on …

Effects Of An Online Diabetes Self-Management Educational Class On Perceived Self-Efficacy In Patients With Type 2 Diabetes Mellitus, Samantha L. Sugarman, Dnp, Ba, Bsn, Msn, Fnp-C

Doctor of Nursing Practice Projects

Background: Diabetes is a complex, chronic disease that, without adequate glycemic control, may result in avoidable complications. Without proper diabetes self-management education, achieving good glycemic control is difficult. Furthermore, lacking self-efficacy to perform such tasks may prevent even the most educated patients from achieving good glycemic control. Studies have shown that live diabetes education has improved self-efficacy in patients with diabetes, but few look at the effects of a lecture-style educational format in an online approach.

Objectives: The purpose of this study is to determine if an online, lecture-style diabetes self-management educational class will improve self-efficacy among patients with type …

The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative …

Surviving Difference: Endocrine-Disrupting Chemicals, Intergenerational Justice, And The Future Of Human Reproduction, Robyn Lee, Roxanne Mykitiuk

Articles & Book Chapters

Endocrine-disrupting chemicals have been identified as posing risks to reproductive health and may have intergenerational effects. However, responses to the potential harms they pose frequently rely on medicalised understandings of the body and normative gender identities. This article develops an intersectional feminist framework of intergenerational justice in response to the potential risks posed by endocrine-disrupting chemicals. We examine critiques of endocrine disruptors from feminist, critical disability and queer standpoints, and explore issues of race and class in exposures. We argue that responding to the risks posed by endocrine disruptors such as brominated flame retardants (BFRs) and phthalates requires developing a …

Telotristat ethyl, a tryptophan hydroxylase inhibitor, was efficacious and well tolerated in the phase 3 TELESTAR study in patients with carcinoid syndrome (CS) experiencing ≥ 4 bowel movements per day (BMs/day) while on somatostatin analogs (SSAs). TELECAST, a phase 3 companion study, assessed the safety and efficacy of telotristat ethyl in patients with CS (diarrhea, flushing, abdominal pain, nausea or elevated urinary 5-hydroxyindoleacetic acid (u5-HIAA)) with < 4 BMs/day on SSAs (or ≥ 1 symptom or ≥ 4 BMs/day if not on SSAs) during a 12-week double-blind treatment period followed by a 36-week open-label extension (OLE). The primary safety and efficacy endpoints were incidence of treatment-emergent adverse events (TEAEs) and percent change from baseline in 24-h u5-HIAA at week 12. Patients (N = 76) were randomly assigned (1:1:1) to receive placebo or telotristat ethyl 250 mg or 500 mg 3 times per day (tid); 67 continued receiving telotristat ethyl 500 mg tid during the OLE. …

Lafora Disease Offers A Unique Window Into Neuronal Glycogen Metabolism, Matthew S. Gentry, Joan J. Guinovart, Berge A. Minassian, Peter J. Roach, Jose M. Serratosa

Molecular and Cellular Biochemistry Faculty Publications

Lafora disease (LD) is a fatal, autosomal recessive, glycogen-storage disorder that manifests as severe epilepsy. LD results from mutations in the gene encoding either the glycogen phosphatase laforin or the E3 ubiquitin ligase malin. Individuals with LD develop cytoplasmic, aberrant glycogen inclusions in nearly all tissues that more closely resemble plant starch than human glycogen. This Minireview discusses the unique window into glycogen metabolism that LD research offers. It also highlights recent discoveries, including that glycogen contains covalently bound phosphate and that neurons synthesize glycogen and express both glycogen synthase and glycogen phosphorylase.

Relationship Between The Dimerization Of Thyroglobulin And Its Ability To Form Triiodothyronine, Cintia E. Citterio, Yoshiaki Morishita, Nada Dakka, Balaji Veluswamy, Peter Arvan

Pharmacy Faculty Articles and Research

Thyroglobulin (TG) is the most abundant thyroid gland protein, a dimeric iodoglycoprotein (660 kDa). TG serves as the protein precursor in the synthesis of thyroid hormones tetraiodothyronine (T₄) and triiodothyronine (T₃). The primary site for T₃ synthesis in TG involves an iodotyrosine acceptor at the antepenultimate Tyr residue (at the extreme carboxyl terminus of the protein). The carboxyl-terminal region of TG comprises a cholinesterase-like (ChEL) domain followed by a short unique tail sequence. Despite many studies, the monoiodotyrosine donor residue needed for the coupling reaction to create T₃ at this evolutionarily conserved …

Systematic In Vivo Evaluation Of The Time-Dependent Inflammatory Response To Steel And Teflon Insulin Infusion Catheters., Jasmin R. Hauzenberger, Julia Münzker, Petra Kotzbeck, Martin Asslaber, Vladimir Bubalo, Jeffrey I. Joseph, Thomas R. Pieber

Department of Anesthesiology Faculty Papers

Continuous subcutaneous insulin infusion (CSII) catheters are considered the weak link of insulin pump therapy. Wear-time considerably varies between patients and the choice of catheter material is based on personal preferences rather than scientific facts. Therefore, we systematically assessed and quantified the inflammatory tissue response to steel versus Teflon CSII catheters over a maximum wear-time of 7 days in swine. Tissue surrounding catheters was analysed using histopathology and quantitative real-time PCR. The area of inflammation increased significantly over time independent of material which was confirmed by an increase in CD68 expression and an increase in mononuclear and neutrophil cell infiltrate …

Barnstable Brown Diabetes Center Faculty Publications

Introduction

In 2015, 11.9% of people with cystic fibrosis (CF) in the United States had osteopenia, 5.1% osteoporosis, and 0.3% experienced a fracture. Screening for CF-related bone disease starts in childhood, and dual energy x-ray absorptiometry (DXA) is the recommended method. It is unknown whether peripheral quantitative computed tomography (pQCT) can detect deficits earlier than DXA. This study compared pQCT and DXA scans in a group of pre-pubertal children with CF and healthy controls.

Methods

This was a cross-sectional study of children at Tanner stage 1. A pQCT scan of the radius at proximal and distal sites was performed plus …

The Impact Of An Educational Intervention To Enhance Self-Management In Type 2 Diabetes Patients, Demetria Bates

Doctoral Dissertations and Scholarly Projects

Type 2 diabetes mellitus is a chronic health condition that requires patients to be engaged in their health care. Knowledge of the disease and self-management skills are key components to improving health and outcomes in diabetes patients. Due to the lack of self-management skills, diabetes patients are at risk for diabetes-related health complications. Hemoglobin A1c is a measure that demonstrates the average blood glucose level, which is an indicator of diabetes control. Medical treatments and education are continuously improving and readily for type 2 diabetes. The purpose of this project was to enhance knowledge and self-management skills among chronic care …
