Filter by:Diabetes Mellitus (DM) includes several metabolic diseases all characterized by high sugar levels in the blood. Although diabetic nephropathy is widespread, its underlying pathophysiological mechanisms remain poorly understood and, so far, little progress has been made to prevent the development of diabetic nephropathy and to delay kidney functions decline. Increasing amount of data based on animal studies support the pathogenic role of tissue hypoxia in the development and progression of diabetic nephropathy. Blood Oxygenation-Level Dependent Magnetic Resonance Imaging (BOLD-MRI) is increasingly used in research to measure cortical and medullary oxygenation in a non-invasive manner. Interestingly, in two cross-sectional clinical studies, we have recently found a positive correlation between high circulating blood glucose levels and cortical R2* levels in type 2 DM patients. This discovery suggests that an increase in glycemia might acutely decrease renal tissue oxygenation. The goal of this study is to investigate the impact of serum glucose on renal tissue oxygenation in healthy subjects and subjects with glucose intolerance.
Raised blood glucose levels can lead to adverse modifications to functional proteins within the body and eventually lead to the development of type 2 diabetes. Fruit polyphenols may help to control glycaemia following a carbohydrate meal or beverage. The aim of this study is to investigate the effects of blackcurrant (BC) and apple (A) extracts on postprandial glycaemia, insulinaemia and plasma gastric inhibitory polypeptide concentrations following a mixed carbohydrate test meal.
The investigators are doing this research for two reasons. The first is to see how the retina (back of your eye) changes when your blood sugar is treated with medication for the first time. This will help us better understand the progression of a condition known as Diabetic Retinopathy. The second reason is to provide diabetic blood samples, which will possibly help identify biomarkers for diabetic retinopathy. Biomarkers are things that indicate the presence of a specific condition, and indicate a higher likelihood of developing that condition.
A 4-month, randomized, prospective, open-label comparison trial of hydroxychloroquine vs. pioglitazone in type 2 diabetic patients inadequately controlled on maximally tolerated doses of metformin plus a sulfonylurea.
Background: Skipping breakfast and/or overeating at evening, has been associated in type 2 diabetic (T2D) individuals, with higher BMI, visceral adiposity, hyperlipidemia, increased overall postprandial glycemia (PPHG) and higher HbA1c. The absence of breakfast is also associated with increased plasma free fatty acids (FFA) along the morning until lunch. High plasma FFA in turn are triggering factor of insulin resistance, by inhibiting insulin mediated glucose uptake in obese and T2D subjects The investigators therefore hypothesize that compared to eating breakfast the prolonged overnight fasting caused by the breakfast omission will result in increased postprandial glycemic response after subsequent isocaloric lunch and dinner in T2D individuals. Objectives: With this aim will study T2D patients in randomized crossover design to consume in two separate days, either 3 standard isocaloric meals: Yes Breakfast condition (YesB) or omit breakfast: no breakfast condition (NoB) and consume only lunch and dinner with the same caloric content. Methods and Study Design: The YesB intervention will consist on three identical meals coating 700 Kcal each: breakfast at 8:00, lunch at 13:00 and dinner at 19:00. The NoB intervention the breakfast will be omitted and the subject continue fasting until lunch. Then the participants will consume identical 700 kcal Lunch at 13:00 and 700 Kcal dinners at 19:00. The investigators will assess plasma glucose, insulin, C-peptide, GLP-1 and FFA with blood samples collected every 30 min up to 180 min after breakfast, lunch and dinner and at the same time point the blood samples will be collected after 8:00 when the breakfast will be omitted. Expected results: The investigators expect that compared to NoB condition, in the YesB condition the postprandial response after lunch and dinner will be reduced for glucose and for FFA, while plasma insulin, C-peptide and GLP-1 postprandial response after lunch and dinner will be enhanced
Few randomized studies have focused on the optimal management of non-ICU patients with type 2 diabetes in Latin America. Objective: Compare safety and efficacy of a basal bolus regimen with analogs and human insulins in general medicine patients admitted to a University Hospital in Asuncion, Paraguay.
Patients will undergo magnetic resonance spectroscopy (MRS) scanning to noninvasively measure intracerebral and plasma metabolite levels at baseline and following 2 and 4 hours of hyperglycemia. Subjects will also undergo a lumbar puncture at a separate occasion to assess cerebrospinal fluid levels of metabolites.
A 4 week prospective, randomized controlled study was carried out to assess the impact of a care delivery intervention which focused on blood glucose (BG) management among adults with type 2 diabetes presenting to the Emergency Department (ED) with BG >/= 200mg/dL (11.1 mmol/L). The intervention was designed by a multi-disciplinary team of ED physicians and nurses, endocrinologists and diabetes educators. The intervention incorporated three components: a guideline-based algorithm for diabetes medication management survival skills diabetes self-management education (DSME); and support for health system navigation. The control group received usual care per the ED's policies and procedures for management of high blood glucose.
The purpose of this study is to compare hyperglycemia and other effects, include 28-day mortality and time to reversal of shock between 100 milligrams and 200 milligrams of hydrocortisone as initial dosage in patients with septic shock.
Purpose of this study is to treat glucocorticoid induced hyperglycemia due to glucocorticoid pulse therapy in a efficacious, safe and convenient way. Patients with acute exacerbation of COPD treated with glucocorticoid pulse therapy and at high risk for glucocorticoid induced hyperglycemia (defined as known type 2 DM or glucose > 10mmol/l at admission) will be randomized to treatment of dapagliflozin or placebo orally, once daily. Percentage of time within glucose target range (3,9-10 mmol/l) and incidence rate of hypoglycemia will be compared between dapagliflozin group and placebo group.
