The Prevalence Of Diabetes In Juveniles, Tatyana Johnson

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Diabetes mellitus, simply known as diabetes, is a metabolic disorder that impacts how the body makes use of glucose or blood sugar. Glucose is the primary supply of energy for the body’s cells, which is controlled by insulin, a pancreatic hormone. Diabetes results in high blood glucose levels (hyperglycemia), which are caused by either insufficient insulin production by the pancreas or ineffective insulin utilization by the body (Dean & McEntyre, 2004). Although there are several types of diabetes, the two main types are type 1 and type 2. Type 1, also known as juvenile diabetes, is an inflammatory condition in …

Liquid Biopsies For Type 2 Diabetes Mellitus: Biomarkers For Disease Risk And Diagnosis, Stephanie Chidester

Dissertations

Background: Type 2 diabetes mellitus (T2DM) has reached epidemic proportions in the United States. There is a critical need for earlier and more effective screening and diagnostic tools. Innovative liquid biopsy technologies may play a key role in meeting this need. Liquid biopsies are a non-invasive, adjunctive tool for determining diagnosis, prognosis, and therapeutic response. This dissertation focuses on two potential applications of liquid biopsy technologies to T2DM: (1) epigenome-wide association studies to identify epigenetic markers of risk for T2DM, and (2) extracellular vesicle (EV)-based biomarker studies to identify and detect markers associated with T2DM development and progression. Dissertation studies: …

Postnatal Β1 Integrin Deficiency In Pancreatic Beta-Cells Impairs Function And Survival, Jason E. Peart

Electronic Thesis and Dissertation Repository

Integrin β1 is essential for pancreatic beta-cell development and maintenance throughout life in rodents and human fetal islets. However, the effects of a postnatal β1 integrin knockout (β1KO) specific to pancreatic beta-cells of mice is undetermined. We generated mice with CreERT recombinase specific to the mouse insulin promoter (MIP), allowing us to induce a β1KO upon injection of tamoxifen (MIPβ1KO model).

At 3-4 weeks of age tamoxifen was injected and mice were sacrificed at 8 (male) and 16 weeks (female) post-tamoxifen. MIPβ1KO mice had impaired glucose tolerance, reduced beta-cell mass and islet density. The impairment in glucose tolerance remained in …

Identification Of The Effects Of Diabetes Mellitus On The Brain, Tryphina A. Mikhail

Honors Undergraduate Theses

As more studies accumulate on the impact of diabetes mellitus on the central nervous system, they resound with the same conclusion - diabetes has a detrimental effect on cognition regardless of the presence of comorbidities. Less consistent however, are the specific mental processes wherein these declines are noticeable, and the structural changes that accompany these reductions in mental capacity. From global atrophy to changes in the volume of gray and white matter, to conflicting results regarding the effects of hypo- and hyperglycemic states on the development of the hippocampus, the studies display a variety of results. The goal of this …

New Beginnings: A Discussion Guide Adaptation For Living With Diabetes Among An Urban American Indian Community, Eudora Lynette Claw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diabetes is a chronic disease where the body has the inability to control the sugar levels in the blood to convert into to usable energy needed to fuel the body's cells. Some common diabetic complications include heart disease, stroke, amputations, and possibly blindness. It can be successfully managed with routine care of monitoring of sugar levels, eating a healthy diet, and daily exercise. The occurrence of type 2 diabetes is rising rapidly worldwide, but is a burden for AI/ANs (American Indian/Alaska Natives) at a substantially disproportionate rate. The purpose of this pilot study was to participate in a one-day curriculum …

Risk Factors For Diabetes Mellitus: A Comparative Analysis Of Subpopulation Differences In A Large Canadian Sample, Michael James Taylor

Electronic Thesis and Dissertation Repository

Objectives: Certain Canadian subpopulations observe numerous modifiable and non-modifiable risk factors for diabetes. This study compares immigrants and Aboriginals (First Nations, Inuit, and Métis) with Canada-born individuals at higher risks for diabetes, and deciphers the determinant differences between them.

Methods: Pooled Canadian Community Health Survey data (2001-2010) were used. Time trends for diabetes within each subsample were calculated using individual survey year prevalence rates; diabetes diagnoses were self-reported (N=33,565). Various risk factors were also examined using logistic regression.

Results: Diabetes prevalence rates significantly increased from 2001 to 2010 for each subpopulation, as well as the total sample: Canada-Born individuals (3.9% …

Gastric Myoelectrical Activity In Patients With Diabetes, Sandra Luberata Holmes

Theses and Dissertations (ETD)

This descriptive, correlational study investigated the associations among gastric myoelectrical activity (GMA), upper gastrointestinal (GI) symptoms, and glucose control. The study also attempted to determine whether any relationship existed between upper GI symptoms, glucose control, age, or length of diagnosis and pattern of GMA identified using electrogastrography (EGG). A total of 25 persons participated in the study. The sample was comprised of 7 healthy controls, 5 patients diagnosed with type 1 diabetes, and 13 patients diagnosed with type 2 diabetes. Electrogastrography was performed for 30 minutes in the fasting state and continued at 30-minute intervals for a total of 1-1/2 …
