Filter by:Bariatric surgery has been proven to be an effective treatment of type 2 diabetes and it has highlighted to role of the small intestine in glucose homeostasis. Improvement of glucose homeostasis occurs just a few days after the bariatric surgery, where parts of the small intestine is bypassed, has been performed. Furthermore, conditioned medium from the duodenum and the jejunum from both diabetic rodents and humans are able to induce insulin resistance in normal mice and in myocytes. Hence the hypothesis is that the small intestine secretes factors that are able to induce insulin resistance. This project aims to study how orally ingested glucose is able to induce insulin resistance and if this response differs in patients with normal glucose tolerance, impaired glucose tolerance and in patients with type 2 diabetes mellitus. To address this question glucose homeostasis will be studied by comparing whole body glucose uptake during a progressively increased oral glucose load with a graded glucose infusion where the blood glucose levels will be kept in the same range as during the oral glucose load in patients with normal glucose tolerance, impaired glucose tolerance and patients with type 2 diabetes mellitus. Previous studied have shown that different metabolites and bile acids could be involved the regulation of glucose homeostasis. Hence, it is possible that the gut regulates metabolites that could be involved in small intestine-induced insulin resistance described above. The aim of this research is to study metabolomics in plasma collected during the oral glucose tolerance test with increasing load of glucose and the graded glucose infusion where plasma glucose level will be held in the same levels as during the oral glucose tolerance test and study the differences in patients with normal glucose tolerance, impaired glucose tolerance and in patients with type 2 diabetes mellitus. The expected results in this study will demonstrate that the gut plays an important role in glucose homeostasis and that this system is dysregulated in type 2 diabetes. More importantly, novel factors derived or regulated from the gut that regulate insulin resistance and glucose tolerance will be identified which could be possible targets for future antidiabetic therapies.
The Personalized Nutrition Project for Prediabetes (PNP3) study will investigate whether personalized diet intervention will improve postprandial blood glucose levels and other metabolic health factors in individuals with prediabetes as compared with the standard low-fat diet.
Background: A significant proportion of pre-diabetics, show macro and micro vascular complications associated with hyperglycaemia. Although many trials have demonstrated the efficacy of lifestyle and pharmaceutical interventions in diabetes prevention, no trial has evaluated the extent to which mid- and long-term complications can be prevented by early interventions on hyperglycaemia. Aims: To assess the long-term effects on multiple complications of hyperglycaemia of early intensive management of hyperglycaemia with linagliptin, metformin or their combination added to lifestyle intervention (LSI) (diet and physical activity), compared with LSI alone in adults with non-diabetic intermediate hyperglycaemia (IFG, IGT or both). Study Design: Investigator initiated (non-commercial), long-term, multi-centre, randomised, partially double blinded, placebo controlled, phase-IIIb clinical trial with prospective blinded outcome evaluation. Participants will be randomised to four parallel arms: 1) LSI + 2 placebo tablets/day; 2) LSI + 2 Metformin tablets of 850 mg/day; 3) LSI + 1 Linagliptin tablets of 5 mg/day and 1 placebo; 4) LSI + 2 tablets of a fixed-dose combination of Linagliptin 2.5mg and Metformin 850 /day. Active intervention will last for at least 2 years. Setting and population: Males and Females with pre-diabetes (IFG, IGT or both) aged 45 to 74 years selected from primary care screening programs in 14 clinical centres from 10 countries: Australia, Austria, Bulgaria, Greece, Italy, Kuwait, Poland, Serbia, Spain and Turkey and . (N=1000) Main Outcomes: The primary endpoint is a combined continous variable: "the microvascular complication índex" (MCI) composed by a linear combination of the Early Treatment Diabetic Retinopathy Study Scale (ETDRS) score (based on retinograms), the level of urinary albumin to creatinine ratio, and a measure of distal small fibre neuropathy (sudomotor test by SUDOSCAN), measured during baseline visit and at 24th and 48th month visits after randomisation. In addition, serological biomarkers of inflammation, vascular damage, non-alcoholic fatty liver disease, insulin secretion, measures of quality of life, sleep quality, neuropsychological evaluation and endothelial function will be also evaluated in a subset of participants.
The lifestyle intervention program focusing on healthy dietary habit and exercise effectively prevents progression to diabetes. Thus, the purpose of this study was to assess the effectiveness of lifestyle intervention program on pre-diabetics subjects in Taiwan.
In the present study glucose metabolism and ectopic lipids in the liver, heart and muscle were investigated in women with the polycystic ovary syndrome (PCOS) and in healthy control subjects.
This project will evaluate distal intestinal bile salt administration in humans by deliving ursodeoxycholic acid (UDCA) into the terminal ileum of subjects with a pre-existing ileostomy and assessing several hormone levels following an oral glucose tolerance test compared to a placebo.
Type 2 Diabetes (T2D) in obese youth is often preceded by a prediabetic state called: Impaired Glucose Tolerance (IGT), which is associated with a pre-existing defect in insulin secretion. This study intends to determine if genetic factors are associated with defects in insulin secretion, the incretin system and hepatic insulin resistance in obese adolescents. The long-term goal of this study is to generate information on both the genetics as well as the pathophysiology of Type 2 Diabetes in Youth, which ultimately might guide the investigators towards better preventive and treatment avenues.
The overarching objective of our work is to provide an inexpensive and scalable m-health tool to increase both volume and intensity of physical activity and reduce sedentary behavior in patients at risk for type 2 diabetes. The objective of this study is to pilot test MapTrek, a text-messaging based intervention.
The proposed study will inform efforts to prevent diabetes and promote weight loss in a high-risk population and generate a reproducible, scalable, and sustainable model for use with other insurer groups and clinical settings that work in immigrant populations with a high burden of chronic disease.
This pilot study aims to determine whether adding a sleep extension and sleep hygiene intervention to an existing lifestyle improvement program improves its efficacy for weight loss in those at risk for diabetes and cardiovascular disease. Half of the participants will receive the Centers for Disease Control's standard PreventT2 program and half of the participants will receive the same program with an additional sleep intervention.
