Active clinical trials for "Hyperglycemia"

Insulin resistant volunteers will choose to undergo an 8-week cold treatment, 2 hours per day, to selective regions of the body enriched with brown fat including neck, supraclavicular and interscapular regions) in combination with electroacupuncture (EA). Their insulin sensitivity and glucose and lipid homeostasis will be measured. The brown fat activation will be assessed by positron emission tomography and computed tomography (PET/CT)-scans and/or serum marker measurements.

Insulin preparation -random assignment to regular insulin lin or lispro insulin as first treatment- was administered at constant infusion rate (0.04 units/Kg/h) in patients presenting blood glucose concentration ≥180 mg/dl and was discontinued when blood glucose concentration ≤140 mg/dl (therapeutic blood glucose concentration drop). Further reduction in blood glucose concentration after discontinuation of insulin infusion was recorded (post-infusional blood glucose concentration drop). During the study period blood glucose concentration, in whole blood, was measured every 30 minutes. At least 6 hours interval was allowed between the 2 treatments.

Stress hyperglycemia is a common phenomenon in cardiac surgery that concerns diabetic and non diabetic patients. It has been shown that perioperative hyperglycemia is an independent risk factor of postoperative mortality and morbidity. The Leuven et al.'s study suggested that strict glycemic perioperative control using an intensive insulin therapy could reduce mortality and morbidity in surgical intensive care's patients. This study included a majority of cardiac surgery patients. Others studies have suggested that the beneficial effect of insulin-based tight perioperative glycemic control might be hampered by iatrogenic hypoglycemia. Moreover, insulin therapy failed to obtain perioperative glycemic stability in most patients. Exenatide (Byetta ®) is an incretin mimetic, characterized by an anti-hyperglycemic effect that depends on the blood glucose level. We hypothesize that continuous intravenous infusion of exenatide could improve perioperative glycemic control and stability and could reduce the risk of iatrogenic hypoglycemia compared to a conventional insulin therapy during the perioperative period of cardiac surgery.

The metabolic syndrome is associated with increased risk of cardiovascular disease and diabetes mellitus. The age-adjusted prevalence of the metabolic syndrome in the United States is 34% for men and 35% for women. Emerging alternative medicine worldwide led investigators to evaluate the efficacy of Crocus sativus (Saffron) and Berberis Vulgaris (barberry fruit) in treatment of metabolic syndrome. Serum total cholesterol, serum LDL cholesterol, serum HDL cholesterol, serum triglyceride, Fasting Blood Sugar and hematocrit measured before and after 45 days of treatment.

The question of a possible hyperglycemic effect from single-dose dexamethasone is an important issue for clinicians managing patients in the intraoperative and postoperative periods. Recent evidence suggests that even moderate elevations in blood glucose levels may be associated with adverse events. The aim of this clinical investigation is to determine whether standard clinical doses of dexamethasone produce hyperglycemia in the perioperative period.

MAIN STUDY: Low glycaemic index (GI) diets are recommended by the Canadian Diabetes Association for treating type 1 and 2 diabetes mellitus (DM), but the role of GI in the management of gestational diabetes(GDM)is not yet clear. The main purpose of this study is to determine the effect of a low GI diet on blood sugar control in women with GDM. The effect of a low GI diet on maternal oxidative stress, pregnancy and delivery outcomes and markers of risk for diabetes after birth in both the mother and baby will also be assessed. SUB-STUDY: The main purpose of the sub-study is to determine if the breast milk (BM) of women with GDM consuming a low GI diet will have a higher antioxidant capacity than the BM of women receiving a medium-high GI diet (control/standard care). The effect of a low glycaemic index diet on maternal dietary intake of specific nutrient-antioxidants (i.e. vitamin C, E, and beta-carotene) (prenatal and postpartum) and concentration of vitamin C, E, and beta-carotene in participants' transitional and mature BM will also be assessed. The ORAC (Oxygen radical absorbance capacity) assay will be used to assess overall antioxidant capacity. The antioxidant capacity of BM in women with GDM will also be compared with that of women without GDM. Hypotheses: MAIN: The use of low-GI foods in the management of GDM reduces postprandial BG and oxidative stress; thereby reducing maternal and infant perinatal complications. SUB-STUDY: Breast milk (BM) of women with GDM consuming a low GI diet will have higher BM antioxidant than women receiving the medium to high GI diet. BM of women with GDM will have lower antioxidant capacity than that of women without GDM.

The Stroke Hyperglycemia Insulin Network Effort (SHINE) Trial is a multicenter, randomized, controlled clinical trial of 1400 patients that will include approximately 60 enrolling sites. The study hypotheses are that treatment of hyperglycemic acute ischemic stroke patients with targeted glucose concentration (80mg/dL - 130 mg/dL) will be safe and result in improved 3 month outcome after stroke.

The main purpose of the study is to determine the effects of 16 weeks of adjunctive pramlintide or exenatide use on glycemic control in Type 1 Diabetes.

The study is a multicenter, prospective, open-label randomized study to compare the safety and efficacy of continuous insulin infusion (CII) via a computer-guided(Glucommander) and a standard paper form protocol among the patients hospitalized in a medical intensive care unit (ICU). .

Critically ill children, including children undergoing heart surgery, commonly develop elevated blood glucose (also known as "blood sugar") levels during their illness, which can lead to poor health outcomes and an increased risk of death. This study will examine the effectiveness of maintaining normal blood glucose levels at decreasing infections and improving recovery in young children undergoing heart surgery.
