A1c Reduction And Weight Loss In A Veteran Population Using Glp-1-Ras, Shelby L. Beutel Darrow

Undergraduate Honors Thesis Collection

Background: Diabetes mellitus is a metabolic disorder defined by high blood glucose. Glucagon-like peptide-1 receptor agonists (GLP-1-RAs) are a newer class of medications that offer potential 2 to 3 kg weight loss and a 1% to 1.5% decrease in A1c. At the Indianapolis Veterans Affairs Medical Center (VAMC), GLP-1-RAs are non-formulary.

Objectives: Primary outcomes included mean change in weight, body mass index (BMI) and A1c in VAMC patients. Secondary outcomes included the comparison to published values, analysis of insulin needs, and analysis of GLP-1-RA discontinuation reasons.

Methods: Indianapolis VAMC patients ages 18-80 with type 2 diabetes who started a GLP-1-RA …

Insulin Actions On Hippocampal Neurons, Shaniya Maimaiti

Theses and Dissertations--Pharmacology and Nutritional Sciences

Aging is the main risk factor for cognitive decline. The hippocampus, a brain region critical for learning and memory formation, is especially vulnerable to normal and pathological age-related cognitive decline. Dysregulation of both insulin and intracellular Ca2+ signaling appear to coexist and their compromised actions may synergistically contribute to neuronal dysfunction with aging. This dissertation focused on the interaction between insulin, Ca2+ dysregulation, and cognition in hippocampal neurons by examining the contributions of insulin to Ca2+ signaling events that influence memory formation. I tested the hypothesis that insulin would increase cognition in aged animals by altering Ca2+-dependent physiological mechanisms involved …
