Filter by:The continuously increasing prevalence of cardiovascular diseases, type-2 diabetes, and COPD is a major health problem in developed countries and is mainly caused by an unhealthy lifestyle. Most important lifestyle related causes of morbidity and mortality are smoking, obesity and physical inactivity, and increasing rates of obesity and physical inactivity in combination with smoking will lead to an increase in the number of patients with lifestyle related diseases in the coming decades. There is, therefore, an urgent need to identify and establish strategies and to implement interventions, allowing for the identification and management of citizens at increased risk of disease. Two recent systematic reviews of general practice based health checks suggest that people at increased risk of a chronic disease may benefit from a targeted approach to health checks. Targeted or selective preventive actions are a generally accepted and well integrated part of the health care system (e.g. treatment of hypertension and hyperlipidemia). However, selective prevention is challenged in terms of how to identify citizens at increased risk of disease in the general population in order to start the indicated preventive actions. The aim of the present pilot study is to test the acceptability, feasibility and short-term effect of a selective preventive program that systematically helps citizens evaluate individual risk of lifestyle related disease and offers targeted and coordinated preventive services in the primary health care sector. The intervention comprises four elements: 1) Systematic collection of information on lifestyle risk factors using questionnaire 2) Risk estimation and stratification into risk groups based on questionnaire data and information from the electronic patient record (EPR) using validated risk estimation models, 3) An individual electronic health profile with personalized advise on lifestyle change and 4) targeted preventive services at the general practitioner (GP) or the municipality for citizens at risk of lifestyle disease and citizens with risk behavior, respectively. The intervention is supported by a patient-centered health information system that facilitates informed patient action and integrates general practice and municipality health care providers.
Patients with type 2 diabetes have many complications in different organs. These complications are extremely frequent and severe: cardiovascular and renal disease, visual impairment, and, more recently, complications affecting bone such as fractures. Conventional methods for the evaluation of fracture risk are based on the Bone Mineral Density (BMD) or FRAX (algorithm for the prediction of osteoporotic fracture risk) are not sufficient in the context of diabetes. Several metaanalyses have shown that, paradoxically, a higher BMD in patients with type 2 diabetes compared to patients not suffering from this disease, independently of body mass index (BMI). The paradoxal increase in fracture risk, despite a high BMD has led to the hypothesis that diabetes induces a modification of the quality and not the quantity of bone. However, there is a lack of data as to bone quality in patients with type 2 diabetes as studies of bone biopsies from patients with type 2 diabetes are extremely rare. The objective of the study is to compare bone quality in patients with type 2 diabetes to that in patients who do not suffer from type 2 diabetes: evaluation of vertebral fractures by osteodensitometry, measurement of Trabecular Bone Score (TBS), and analysis of bone quality in biopsies (advanced glycation end products (AGE), contents of bone matrix and analysis of mineralization). The results will then be correlated with blood/urinary markers with the objective to determine one/several non-invasive biomarkers for bone status in diabetic patients.
To assess the effect of sodium-glucose cotransporter 2 (SGLT-2) inhibitors on blood pressure and urinary angiotensinogen. This is a cross over study design, where 40 subjects will receive Dapagliflozin for 6 weeks followed by placebo for 6 weeks, or placebo for 6 weeks followed by Dapagliflozin for 6 weeks. In addition there will be an arm of 10 subjects who will receive sulfonylurea in an open label as a comparative to the cross over subjects to assess if the effect of Dapagliflozin may also be in part due to improved glycemic control.
In normal physiology, glucagon from pancreatic alpha cells plays an important role in maintaining glucose homeostasis via its regulatory effect on hepatic glucose production. Patients with type 2 diabetes exhibit elevated plasma glucagon levels in the fasting state, and in response to ingestion of glucose or a mixed meal.glucagon, glucagon concentrations fail to decrease appropriately and may even increase. This diabetic hyperglucagonaemia may therefore contribute importantly to the hyperglycaemia of the patients. Several glucose-lowering treatment modalities have been shown to affect glucagon levels in patients with type 2 diabetes, but the role of glucagon in the glucose-lowering effects of these treatment modalities has been difficult to discern. By using a glucagon receptor antagonist (GRA) the investigators will exploit glucagon receptor antagonism to delineate the role of glucagon during treatment with sodium-glucose co-transporter 2 (SGLT2) inhibitors and dipeptidyl peptidase 4 (DPP-4) inhibitors, which have been shown to increase and decrease plasma glucagon levels, respectively.
This study is undertaken to search whether glucagon-like peptide-1 (GLP-1) analogue, Liraglutide, by enhancing clock gene and AMPK-SIRT-1 mRNA expression, may reverse the metabolic abnormalities of type 2 diabetes, improving overall glycemic excursion, inflammatory cytokines and β-cell function in type 2 diabetes individuals. The investigators aim is to compare the effect of 40 days treatment with Liraglutide (LIR) vs. 40 days with placebo (PLA) in T2D participants on the following end points: Primary end-points: - Change in the oscillation of CG (i.e. CLOCK, BMAL1, Per1, Per2, Cry1, Cry2, Rev-erb-alpha Ror-alpha), AMPK, SIRT1 and inflammatory cytokines mRNA expression in white blood cells (WBCs). Secondary end-points: - Overall daily glycemic variation assessed with continuous glucose monitoring system (CBMS) - Serum levels of inflammatory cytokines (TNF-α, IL-1β, IL-6) - β-Cell function derived from glucose and insulin response to OGTT
Obesity is a major risk factor for cardiovascular disease and diabetes. Weight loss is an important therapeutic goal for overweight and obese patients to reduce their risk of developing cardiovascular disease and diabetes. Liquid meal replacements (LMRs) are simple tools that may aid in weight loss and may improve weight-related risk cardiometabolic risk factors. There is a need to synthesize the evidence on LMRs and cardiometabolic risk to inform clinical practice guidelines. The authors propose to conduct a series of systematic review and meta-analysis of randomized controlled trials to evaluate the effect of LMRs on 4 areas of cardiometabolic risk: markers of adipsoity, glycemic control, established lipid targets, and blood pressure.
Despite advances in the prevention and treatment of type 2 diabetes, its prevalence continues to rise worldwide. There is a need for new modalities to improve metabolic control in individuals with type 2 diabetes and those who are overweight or obese and at risk for type 2 diabetes. Contrary to the concerns raised about the adverse role of fructose in metabolic health, various lines of evidence suggest that fructose and its epimers may improve the metabolic handling of glucose through inducing glycogen synthesis. Recent small trials in humans suggest that catalytic doses (=<10g/meal) of fructose and its epimers (allulose, tagatose, and sorbose) may reduce postprandial glycemic responses to carbohydrate loads (i.e., oral glucose tolerance test or a starch load) in people with and without type 2 diabetes. There is also limited evidence that these acute effects may manifest as longer term improvements in glycemic control. There is an urgent need to synthesize the evidence of the effects of fructose and its epimers on postprandial carbohydrate metabolism.
Adipose tissues, which include white adipose tissue (WAT) and brown adipose tissue (BAT), play an essential role in regulating whole-body energy homeostasis. Recent studies also reveal the presence of a subset of cells in WAT that could be induced by environmental or hormonal factors to become "brown-like" cells, and this "beigeing" process has been suggested to have strong antiobesity an antidiabetic benefits. More recently, one study showed that Short-term cold acclimation (10 days) improved insulin sensitivity, but did not activate the browning of subcutaneous white adipose in patients with type 2 diabetes mellitus. Here, investigators hypothesize that a chronic cold acclimation can activate the the browning of subcutaneous white adipose in patients with type 2 diabetes mellitus.
The purpose of this study is to determine if oral of L-citrulline (3 grams/day) for 3 weeks provided in mid-pregnancy to pregnant women with type 2 diabetes will increase the plasma L-arginine/ADMA ratio, lower maternal blood pressure and increase maternal levels of placental growth factor (PlGF).
The aim of the study is to explore short and longer-term effects of the Endobarrier™ implantation on insulin resistance and beta-cell function assessed by repeated Botnia clamps. In addition changes in gut peptides and gut permeability after implantation of a removable duodeno-jejunal bypass device to induce diabetes remission in obese subjects with sub-optimally controlled type 2 diabetes mellitus will be determined. Further changes in body weight and body composition, the change in global cardiovascular risk from baseline to 12 months, estimated using the UKPDS risk engine will be recorded.
