Exendin-(9,39) has been shown to have effects on beta-cell function, and after gastric bypass, to accelerate gastrointestinal transit. - infused at rates of 300pmol/kg/min. Given that gastrointestinal transit is typically delayed by Glucagon-Like Peptide-1 (GLP-1) and also that this hormone causes decreased food intake through increased satiation, it is reasonable to expect an effect of Exendin-9,39 on appetite. This may help explain the effects of gastric bypass on food intake.

Diabetes mellitus is a common condition which is defined by persistently high blood sugar levels. This is a frequent problem that is most commonly due to type 2 diabetes. However, it is now recognized that a small portion of the population with diabetes have an underlying problem with their pancreas, such as chronic pancreatitis or pancreatic cancer, as the cause of their diabetes. Currently, there is no test to identify the small number of patients who have diabetes caused by a primary problem with their pancreas.

The goal of this study is to develop a test to distinguish these ...

While the potential clinical uses of pulsed electromagnetic field therapy (PEMF) are extensive, we are focusing on the potential benefits of PEMF on vascular health. We are targeting, the pre diabetic - metabolic syndrome population, a group with high prevalence in the American population. This population tends to be overweight, low fitness, high blood pressure, high triglycerides and borderline high blood glucose.

The purpose of this study is to assess the effects of a nighttime rise in cortisol on the body's glucose production in type 2 diabetes.

As the global epidemic of obesity and diabetes mellitus spreads, an exponential rise in incident chronic kidney disease (CKD) complicated by end stage renal disease (ESRD) is predicted, leaving healthcare systems overwhelmed worldwide. Hence, there is urgent need for novel therapies to slow the progression of DKD and optimize the health of this patient population. The purpose of this study is to examine the effect of a supplement on mesenchymal stem cells, physical body function (or frailty), kidney function, and total clearance of senescent cells in individuals with CKD. At present, we are enrolling participants with CKD, with a subset ...

The purpose of this study is to track the treatment burden experienced by patients living with Type 2 Diabetes Mellitus (T2DM) experience as they work to manage their illness in the context of social distancing measures. 

To promote social distancing during the COVID-19 pandemic, health care institutions around the world have rapidly expanded their use of telemedicine to replace in-office appointments where possible.1 For patients with diabetes, who spend considerable time and energy engaging with various components of the health care system,2,3 this unexpected and abrupt transition to virtual health care may signal significant changes to ...

The primary purpose of this study is to prospectively assess symptoms of bloating (severity, prevalence) in patients with diabetic gastroparesis.

The MADIT S-ICD trial is designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy.

The purpose of this study is to measure and characterize specific immune cell abnormalities found in patients who have type 1 diabetes and may or may not be on the waiting list for either a pancreas alone or a pancreas and kidney transplant.

This protocol is being conducted to determine the mechanisms responsible for insulin resistance, obesity and type 2 diabetes.

To compare the effect of senolytic drugs on cellular senescence, physical ability or frailty, and adipose tissue-derived MSC functionality in patients with chronic kidney disease.

Primary Objectives:
To assess the efficacy of a single 3-day treatment regimen with dasatinib and quercetin (senolytic drugs) on clearing senescent adipose-derived MSC in patients with CKD.

To assess the efficacy of a single 3-day treatment regimen with dasatinib and quercetin (senolytic drugs) on improving adipose-derived MSC functionality in patients with CKD.

Secondary Objective:
To assess the short-term effect of a single 3-day treatment regimen with dasatinib and quercetin (senolytic drugs) on ...

The purpose of this study is to evaluate the effect of Aramchol as compared to placebo on NASH resolution, fibrosis improvement and clinical outcomes related to progression of liver disease (fibrosis stages 2-3 who are overweight or obese and have prediabetes or type 2 diabetes).

The purpose of this research is to determine if CGM (continuous glucose monitors) used in the hospital in patients with COVID-19 and diabetes treated with insulin will be as accurate as POC (point of care) glucose monitors. Also if found to be accurate, CGM reading data will be used together with POC glucometers to dose insulin therapy.

The purpose of this study is to evaluate the ability of appropriately-trained family physicians to screen for and identify Diabetic Retinopathy using retinal camera and, secondarily, to describe patients’ perception of the convenience and cost-effectiveness of retinal imaging.

The purpose of this study is to use multiple devices to measure blood sugar changes and the reasons for these changes in healthy and diabetic children.

The primary purpose of this study is to evaluate the impact of dapagliflozin, as compared with placebo, on heart failure disease-specific biomarkers, symptoms, health status, and quality of life in patients who have type 2 diabetes and chronic heart failure with reduced systolic function.

The purpose of this study is gain the adolescent perspective on living with type 1 diabetes.

The purpose of this study is to assess painful diabetic peripheral neuropathy after high-frequency spinal cord stimulation.

The purpose of this study is to understand the day-to-day variability in stomach emptying and gastrointestinal (GI) transit in patients with digestive symptoms. This information will be useful for interpreting the results of stomach emptying studies in future.

The purpose of this study is to examine the evolution of diabetic kindey injury over an extended period in a group of subjects who previously completed a clinical trial which assessed the ability of losartan to protect the kidney from injury in early diabetic kidney disease. We will also explore the relationship between diabetic kidney disease and other diabetes complications, including neuropathy and retinopathy.

The purpose of this study is to evaluate the effietiveness of remdesivir (RDV) in reducing the rate of of all-cause medically attended visits (MAVs; medical visits attended in person by the participant and a health care professional) or death in non-hospitalized participants with early stage coronavirus disease 2019 (COVID-19) and to evaluate the safety of RDV administered in an outpatient setting.
