Low Dose Fat-Induced Insulin Resistance
Diabetes MellitusType 22 moreThe primary goal of this study is to determine the dose of fatty acids that acutely induces mild insulin resistance in healthy volunteers. We hypothesize that a low-dose of fatty acid infusion (Intralipid/heparin) will cause a mild insulin resistance. The dose of fatty acid infusion that reliably causes mild insulin resistance will be selected for use in future studies.

Type 2 DiabetesThe purpose of this study is to examine the effect of 4 weeks of Citrulline supplementation on macro- and microvascular function during acute hyperglycemia in middle-aged and older adults with type 2 diabetes.
Study of Subcutaneously Administered ENT-03 for the Treatment of Obesity and Diabetes
ObesityDiabetes Mellitus1 moreSingle center, single-dose, randomized, placebo-controlled, dose-escalating study to evaluate, safety, tolerability, pharmacokinetics, and pharmacodynamics of escalating doses of ENT-03S in obese but otherwise healthy subjects and in subjects with obesity and Type 2 diabetes.
Fresh Carts for Mom's to Improve Food Security and Glucose Management
Gestational Diabetes Mellitus in PregnancyType 2 Diabetes MellitusThis study will look at the benefit of decreasing food insecurity and improving glucose control among women who either report gestational diabetes (GDM) at 20-28-weeks or have type 2 diabetes (T2DM) with a confirmed pregnancy. Participants will receive a grocery prescription with delivery through Instacart at the start of the study or after 12 weeks or frozen medically tailored meals delivered from Door Dash. Researchers will compare the grocery prescription program, MTM (medically tailored meals), relative to standard of care to see if the impact on these food as medicine programs can improve glucose control over 12-weeks as compared to standard of care.
Flash CONtinous Glucose Monitoring in TRansition to Outpatient: Libre for Type 2 Diabetes Mellitus...
Type 2 Diabetes Treated With InsulinThis is a pilot study of the use of flash glucose monitoring (FGM) to assess glycemic control, behavioural, quality of life benefits and manpower utilization in poorly controlled T2DM patients on insulin in the transitional care period after discharge from hospital.
Accuracy of Dexcom G6® and FreeStyle Libre® Sensors in Standardized Hypoxemia Conditions
Type 1 Diabetes MellitusType 2 Diabetes MellitusThe major aim is to evaluate accuracy of 2 Continuous Glucose Monitoring Systems (CGMS) : Dexcom G6® and FreeStyle Libre® in standardized hypoxemia conditions (artificial normobaric hypoxia). Our purpose is to demonstrate the good performance and calibration of these CGM sensors in hypoxemia conditions.
Assessment of Dapagliflozin on Vascular Health in Patients With Type 2 Diabetes
Diabetes MellitusType 21 morePatients with Type 2 Diabetes Mellitus (T2DM) have changes in blood vessel health that can lead to a higher chance of developing heart attacks or strokes. New medications for T2DM including dapagliflozin, which is a Sodium-Glucose Cotransporter-2 inhibitor (SGLT2) inhibitor, may help protect the heart and blood vessels. The overarching objective of this mechanistic study is to learn how a Sodium-Glucose Cotransporter-2 (SGT2) inhibitor, dapagliflozin, impacts vascular health in patients with Type 2 Diabetes Mellitus (T2DM). The investigators will compare the changes in vascular health to changes in endothelial cell (EC) phenotype including non-coding RNA (ncRNA) to develop evidence supporting the mechanism of cardiovascular benefit of SGLT2 inhibitors. This study will provide novel information regarding the mechanism of effects of novel treatments for endothelial function and vascular health in patients with T2DM to reduce cardiovascular (CV) risk. The research aims to assess the: effects of dapagliflozin on EC phenotype. impact of dapagliflozin on vasodilator function and additional measures of vascular health including arterial stiffness and circulating markers of vascular health.
Pharmacogenetics of Response to GLP1R Agonists
ObesityDiabetes Type 2Overweight/obese otherwise healthy volunteers will be recruited from the Old Order Amish population in Lancaster County, PA. Lancaster County, PA. Pharmacodynamic responses to GLP1R agonist will be assessed by conducting frequently sampled intravenous glucose tolerance tests (FSIGT) both before and after semaglutide for six weeks. The proposal proposes two specific aims: Specific Aim #1. To identify genetic variants associated with effects of a GLP1R agonist to enhance glucose-stimulated first phase insulin secretion in the two FSIGTs (before and after administration of drug). Specific Aim #2. To identify genetic variants associated with the effect of a GLP1R agonist to accelerate the rate of glucose disappearance as assessed in the two FSIGTs (before and after administration of drug). Genotyping will be conducted using a high-density array with comprehensive coverage of DNA sequence variants. In addition, the analysis will leverage a global imputation panel generated from 1,025 Amish individuals.
