The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey

Scholarly and Creative Works Conference (2015 - 2021)

Type 1 Diabetes Mellitus accounts for approximately 5% of the diabetic population (CDC, 2015). Numerous complications must be avoided when a diabetic is insulin dependent. Women who are diabetic who are planning to conceive a family have special considerations. Little research has been focused into how to best manage Type 1 diabetics during pregnancy. Since Type 1 diabetes is predominantly diagnosed between birth and 30 years of age, many Type 1 diabetics have potential to become pregnant without knowing how to best manage their diabetes. Poor glycemic control in diabetics has been related to miscarriages, stillbirths, malformations, and macrosomia (Lapolla, …

Cancer As A Metabolic Disease, Javaria Haseeb

Honors Senior Capstone Projects

Despite decades of intensive scientific and medical efforts to develop efficient and effective treatments for cancer, it remains one of the prime causes of death today. For example, in 2016, there will be an estimated 1,685,210 new cases of cancer and 595,690 deaths due to cancer in the United States alone (National Cancer Institute). Worldwide in 2012, there were an estimated 14 million new cases of cancer and 8.2 million deaths due to cancer. In order to come up with better methods of detection and more successful modes of treatment, it is crucial that scientists understand the depth of not …

Promotion Of New Diabetes Products In The District Of Columbia, Joy Eckert, Dilpan Sundaramoorthy, Alycia Hogenmiller

GW Research Days 2016 - 2020

Background: Growth in pharmaceutical expenditures for diabetes outpaced growth in diabetes prevalence. Prescribers accepting gifts and meals from pharmaceutical companies have been linked with higher prescription rates and costs[1]. Pharmaceutical marketing to these prescribers and patients often promotes newer, more expensive drugs, such as the GLP-1 analogues and SGL-2 inhibitors. These two drug classes are more expensive but no more effective than metformin,[2] the recommended first-line treatment for diabetes, and the oldest and cheapest available treatment. We investigated how cost of diabetes treatment was affected by marketing practices in the District of Columbia.

Flexible Dieting And Metabolic Adaptation During Weight Loss: A Comprehensive Review, Bryce Lahaie

Senior Honors Projects

Flexible dieting is a ubiquitous method of eating among the fitness population. It is not a diet, but rather a nutritional concept that refutes any diet that promotes cutting out entire foods or food groups as a method to lose weight. It is a structured and science-based method of eating that involves tracking calories through monitoring the three main macronutrients: carbohydrates, fats, and proteins. These macronutrients are individualized and adjusted for muscle growth, fat loss, or weight maintenance in order to optimize intake to facilitate the manipulation of body composition. Flexible dieting is a disciplined method of eating that teaches …

Causal Pathways From Enteropathogens To Environmental Enteropathy: Findings From The Mal-Ed Birth Cohort Study, Margaret N. Kosek, Zulfiqar Ahmed Bhutta, Anita K. M. Zaidi, Imran Ahmed, Syed Asad Ali, Muneera Rasheed, Sajid Bashir Soofi, Ali Turab, Didar Alam, Shahida Qureshi

Department of Paediatrics and Child Health

Background: Environmental enteropathy (EE), the adverse impact of frequent and numerous enteric infections on the gut resulting in a state of persistent immune activation and altered permeability, has been proposed as a key determinant of growth failure in children in low- and middle-income populations. A theory-driven systems model to critically evaluate pathways through which enteropathogens, gut permeability, and intestinal and systemic inflammation affect child growth was conducted within the framework of the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) birth cohort study that included children from eight countries. …

Sex-Dependent Effects Of Ho-1 Deletion From Adipocytes In Mice, Peter A. Hosick, Mary Frances Weeks, Michael W. Hankins, Kyle H. Moore, David E. Stec

Department of Exercise Science and Physical Education Scholarship and Creative Works

Induction of heme oxygenase-1 (HO-1) has been demonstrated to decrease body weight and improve insulin sensitivity in several models of obesity in rodents. To further study the role of HO-1 in adipose tissue, we created an adipose-specific HO-1 knockout mouse model. Male and female mice were fed either a control or a high-fat diet for 30 weeks. Body weights were measured weekly and body composition, fasting blood glucose and insulin levels were determined every six weeks. Adipocyte-specific knockout of HO-1 had no significant effect on body weight in mice fed a high-fat diet but increased body weight in female mice …

Emerging Roles Of Xenobiotic Detoxification Enzymes In Metabolic Diseases, Michael C. Petriello, Jessie B. Hoffman, Andrew J. Morris, Bernhard Hennig

Superfund Research Center Faculty Publications

Mammalian systems have developed extensive molecular mechanisms to protect against the toxicity of many exogenous xenobiotic compounds. Interestingly, many detoxification enzymes, including cytochrome P450s and flavin-containing monooxygenases, and their associated transcriptional activators [e.g. the aryl hydrocarbon receptor (AhR)], have now been shown to have endogenous roles in normal physiology and the pathology of metabolic diseases. This mini-review will focus on two such instances: the role of flavin-containing monooxygenase 3 (FMO3) in the formation of the cardiometabolic disease biomarker trimethylamine-N-oxide (TMAO) and the role of AhR as a sensor of endogenous ligands such as those generated by the gut microbiota. Understanding …

Ux007 For The Treatment Of Long Chain-Fatty Acid Oxidation Disorders: Safety And Efficacy In Children And Adults Following 24weeks Of Treatment., J Vockley, B Burton, G T Berry, N Longo, J Phillips, Pranoot Tanpaiboon, +Several Additional Authors

Pediatrics Faculty Publications

BACKGROUND: Long-chain fatty acid oxidation disorders (LC-FAOD) lead to accumulation of high concentrations of potentially toxic fatty acid intermediates. Newborn screening and early intervention have reduced mortality, but most patients continue to experience frequent hospitalizations and significant morbidity despite treatment. The deficient energy state can cause serious liver, muscle, and heart disease, and may be associated with an increased risk of sudden death. Triheptanoin is a medium odd-chain fatty acid. Anaplerotic metabolites of triheptanoin have the potential to replace deficient tricarboxylic acid (TCA) cycle intermediates, resulting in net glucose production as a novel energy source for the treatment of LC-FAOD. …

Background

The link between DNA methylation, obesity, and adiposity-related diseases in the general population remains uncertain.

Methods and Findings

We conducted an association study of body mass index (BMI) and differential methylation for over 400,000 CpGs assayed by microarray in whole-blood-derived DNA from 3,743 participants in the Framingham Heart Study and the Lothian Birth Cohorts, with independent replication in three external cohorts of 4,055 participants. We examined variations in whole blood gene expression and conducted Mendelian randomization analyses to investigate the functional and clinical relevance of the findings. We identified novel and previously reported BMI-related differential methylation at 83 CpGs …

Disorders Of Metal Metabolism, Carlos Ferreira, William A. Gahl

Pediatrics Faculty Publications

Trace elements are chemical elements needed in minute amounts for normal physiology. Some of the physiologically relevant trace elements include iodine, copper, iron, manganese, zinc, selenium, cobalt and molybdenum. Of these, some are metals, and in particular, transition metals. The different electron shells of an atom carry different energy levels, with those closest to the nucleus being lowest in energy. The number of electrons in the outermost shell determines the reactivity of such an atom. The electron shells are divided in sub-shells, and in particular the third shell has s, p and d sub-shells. Transition metals are strictly defined as …

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards

Electronic Theses and Dissertations

There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …

Neonatal Hypoglycemia In Diabetic Mothers: A Systematic Review, Brook T. Alemu, Olaniyi Olayinka, Hind A. Baydoun, Matthew Hoch, Muge Akpinar-Elci

Community & Environmental Health Faculty Publications

Hypoglycemia occurs in approximately 8-30% of neonates born to mothers with diabetes. The full extent of the individual and contextual risk factors of hypoglycemia remains unclear and no systematic review of the available studies exists to date. We identified published studies using PubMed and EBSCO host search engines. A modified STROBE statement was used to assess studies' strengths, weaknesses, and generalizability. A total of 16 articles were eligible for full text review. The clinical risk factors in these studies were broadly classified into two: infant-related and mother-related risk factors. The identified infant-related risk factors were SGA, macrosomia, prematurity, lower cord …

Cardiometabolic Risk Factors, Metabolic Syndrome And Pre-Diabetes In Adolescents In The Sierra Region Of Ecuador, Sharon L. Casapulla, Cheryl A. Howe, Gabriela Rosero Mora, Darlene Berryman, Mario J. Grijalva, Edgar W. Rojas, Jay H. Shubrook

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Background: Excess weight (overweight and obesity) is the major modifiable risk factor for type 2 diabetes mellitus (T2DM) and other non-communicable diseases. However, excess weight may not be as predictive of diabetes risk as once thought. While excess weight and other obesity-related non-communicable diseases are of growing concern in low-middle income countries in Latin America, there is limited research on risk factors associated with T2DM in adolescents. This study investigated prevalence of overweight, obesity, prediabetes, diabetes and metabolic syndrome in adolescents in Ecuador.

Methods: A cross-sectional study was conducted with 433 adolescents from two schools in a small …

Repurposing Diabetes Drugs To Treat Insulin Resistance In Alzheimer’S Disease‌, Yael Lazarus

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease is a neurodegenerative condition which results in a significant decline in cognitive status. Novel treatment approaches for Alzheimer’s are sorely needed, as current medications for the disease offer only marginal clinical benefit. Research has discovered a connection between the pathology of Alzheimer’s and Type 2 Diabetes, two serious and seemingly unrelated disorders. Clinical studies have shown that Alzheimer’s disease is associated with brain insulin resistance similar to the pathology of Type 2 Diabetes. This observation has led to the notion that drugs developed for the treatment of Type 2 Diabetes may be beneficial in modifying the cognitive function …

The Role Of Progesterone Receptor Membrane Component 1 In Receptor Trafficking And Disease, Kaia K. Hampton

Theses and Dissertations--Pharmacology and Nutritional Sciences

The progesterone receptor membrane component 1 (PGRMC1) is a multifunctional protein with a heme-binding domain that promotes cellular signaling via receptor trafficking, and is essential for some elements of tumor growth and metastasis. PGRMC1 is upregulated in breast, colon, lung and thyroid tumors. We expanded the analysis of PGRMC1 in the clinical setting, and report the first analysis of PGRMC1 in human oral cavity and ovarian tumors and found PGRMC1 to correlate with lung and ovarian cancer patient survival. Furthermore, we discovered a specific role for PGRMC1 in cancer stem cell viability. PGRMC1 directly associates with the epidermal growth factor …

Fructose And Its Contribution To Cardiovascular Disease And Metabolic Syndrome, Jessica Anderson

Physician Assistant Scholarly Project Posters

The incidence of obesity, cardiovascular disease, and combination of symptoms classified as “metabolic syndrome” that eventually leads to type 2 diabetes have risen dramatically over the past few decades. The current dietary guidelines that advised patients to avoid dietary fats were originally developed in the 1960’s. This led the way for food manufacturers to remove fats in processed foods and replace them with sugars, particularly fructose. At the time there was no clinical trial data that definitively supported these guidelines.

The increased use of fructose as a food additive has dramatically increased the per-capita consumption of this sugar. More recent …

Analysis Of Metabolic Syndrome As A Modifiable Risk Factor For Prostate Cancer, Michael Butler

Physician Assistant Scholarly Project Posters

• Prostate cancer and metabolic syndrome are both prevalent among men in developed countries with peak incidence after age 50.

• Prostate cancer has no known modifiable risk factors.

• Most risk factors for metabolic syndrome are modifiable.

• If metabolic syndrome is identified as contributing to the risk of prostate cancer it would give an element of self determination to men at risk for prostate cancer.

• Past studies provide conflicting results in the correlation between these two conditions.

• A literature review was performed to evaluate consistencies in current literature.

• Metabolic syndrome or its components do not …

Sucrase-Isomaltase Deficiency, An Under Considered Diagnosis, Lindsay Venn

Physician Assistant Scholarly Project Posters

• Persistent gastrointestinal (GI) complaints are a common problem in patients presenting to family practice for care.

• Irritable bowel syndrome (IBS) is a diagnosis that adult patients are labeled with when clinicians have exhausted their differential list and no other cause of their GI symptoms can be confirmed.

• Sucrase-isomaltase deficiency (SID) has been historically shown to present early in life as a congenital disorder, but researchers are now recognizing occurrence later in life as a mild or secondary disorder.

• The literature emphasizes the disconcerting prevalence of sucrase-isomaltasedeficiency (SID), the persistent symptoms associated with it, and the need …

Ethnic Differences In Risk Factors For Obesity Among Adults In California, The United States, Liang Wang, Jodi L. Southerland, Kesheng Wang, Beth A. Bailey, Arsham Alamian, Marc A. Stevens, Youfa Want

ETSU Faculty Works

Little attention has been given to differences in obesity risk factors by racial/ethnic groups. Using data from the 2011-2012 California Health Interview Survey, we examined differences in risk factors for obesity among Whites, Latinos, Asians, and African Americans among 42,935 adults (24.8% obese). Estimates were weighted to ensure an unbiased representation of the Californian population. Multiple logistic and linear regression analyses were used to examine the differences in risk factors for obesity. Large ethnic disparities were found in obesity prevalence: Whites (22.0%), Latinos (33.6%), African Americans (36.1%), and Asians (9.8%). Differences in risk factors for obesity were also observed: Whites …

The Impacts Of Childhood Obesity On Adult Health And Quality Of Life‌, Miriam Weinstock

The Science Journal of the Lander College of Arts and Sciences

Obesity has emerged as one of the most preeminent concerns of the modern era. Thirty six percent of our country’s citizens are classified as obese and six percent qualify as extremely obese. Developing obesity as an adult is fairly common, but countless studies have shown a direct correlation between childhood obesity and remaining severely overweight as an adult. Aside from the physical and aesthetic discomfort of maintaining superfluous girth, the health hazards threatening the obese population are extremely discomfiting. The enormity of the issue requires extensive study so that society can educate themselves of the dangers and how to prevent …
