Filter by:The purpose of this study is to investigate the effect of location of feeding on glycemic control in critically ill patients. The investigators hypothesize that glycemic control in critically ill patients who receive enteral nutrition through postpyloric location (beyond stomach) will have better glycemic control compared to critically ill patients fed gastrically.
Type 2 diabetes affects the ability of the body to process glucose (sugar). Under fasting conditions, the liver is able to make sugar to maintain glucose levels in an important process called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to regulate levels of glucose in the body by communicating with the liver. This process can be impaired in people with type 2 diabetes, and can contribute to the high level of glucose seen in these individuals. The purpose of this study is to understand how activating control centers of the brain with a medication called diazoxide can affect how much glucose (sugar) is made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn can lead to diabetes complications.
Insulin resistance (IR), beyond its well-defined role in the appearance and progression of diabetes mellitus (DM), is the recognized pathogenetic factor underlying vascular aging. Recently, the existence of a "cerebral" IR, responsible of the appearance and progression of many forms of dementia and mild cognitive impairment (MCI), has been hypothesized. On the other hand, it is well known that DM acts as a cardiovascular (CV) risk factor per se. In the last years it has been demonstrated that also glucose normotolerant subjects who exhibit plasma glucose levels >155 mg/dL 1h-post load, have a CV risk similar to that of diabetic patients. Thus, these category of subjects is characterized by IR and, being MCI the expression of IR in the brain, the principal hypothesis of our study is that these subjects may also develop neuropsychological alterations, earlier with respect of the general population.
Risk-patients for diabetes or patients that are diagnosed with this condition but who are not treated with insulin are randomized two times, according to diet and according to the type of support: Randomization with regard to carbohydrate restriction (25-30 E% or < 10E%). Randomization with regard to type of psychological support. Either according to Acceptance and Commitment Therapy or to traditional cognitive behavioral therapy. Both kinds of psychological support is given as group therapy. Two-hundred patients are recruited and each patient is followed for two years.
Because prevalence of glucose metabolism disorders is high in patients with coronary disease, the Oral Glucose Tolerance Test (OGTT) is recommended in all patients without diabetes after an acute coronary syndrome (ACS). However, there are some concerns about its performance in clinical practice. The aim of our study was to evaluate, after an acute coronary syndrome (ACS), the feasibility and efficacy of the OGTT in a cardiac rehabilitation (CR) center in comparison with its real application in the whole French population.
In this explorative randomized clinical study, the investigators aim to study metabolic, cellular, and molecular changes that occur during weight loss in obese subjects with and without type 2 diabetes. Using novel "imiomics" (imaging technique using PET/MR bioinformatics) analyses to examine possible metabolic differences between energy restricted diet and gastric by-pass surgery on whole-body and tissue specific insulin sensitivity, glucose tolerance, metabolite and protein profiles, fatty acid metabolism, ectopic fat content, and gene expression in adipose tissue. This study aims to identify novel biomarkers and drug targets for type 2 diabetes as well as validate promising and established biomarkers in an interventional model for improved glucose metabolism.
Introduction This study evaluates the effect on glucose, lipid and bone metabolism following knee orthopedic procedures in healthy and physically active individuals. The sedentary rehabilitation period following these procedures may impact negatively on glucose, lipid and bone metabolic pathways, whereas the more physically active rehabilitation period instituted 6 weeks after surgery is hypothesized to impact positively. Perspective This study will establish whether the well-known effects on glucose, lipid and bone metabolism of a sedentary lifestyle can be observed already following 6 weeks of physical inactivity in otherwise healthy and physically fit young and middle aged individuals. Investigators will thereby add knowledge to previous findings following strict bed-rest in healthy individuals on glucose, lipid and bone metabolism. In a clinical perspective it is important to examine the extent to which healthy individuals deteriorate in various metabolic pathways to better understand the pathophysiology behind these defects both in healthy individuals and in patients, who undergo bed rest or an equal reduction in physical activity as part of their rehabilitation. Study design 16 physical active non-diabetic individuals of age 18 - 50 years who are undergoing knee surgical procedures at the Arthroscopic Center at Amager/Hvidovre Hospitals are recruited as cases for this case-control study. 10 non-diabetic control subjects matched for age, gender and physical activity are recruited to establish a reference level. - The individuals will bring in morning spot urine for measurement of soluble urokinase plasminogen activating receptor (suPAR), creatinine, albumin and orosomucoid. Weight and height and waist and hip circumference will be measured. - Oral glucose tolerance test (OGTT) with ingestion of 75 g glucose during 5 min from baseline (0 min). Plasma for glucose, insulin, C-peptide, non-esterified fatty acid (NEFA) will be drawn - Before OGTT blood will be drawn for measurement of HbA1c, total cholesterol, LDL, HDL, triglyceride, Na, K, creatinine, hemoglobin (HgB), C-reactive protein (CRP), leukocytes, alanintransaminase (ALAT), alkaline phosphatase, Ca++, D vitamin, TSH, bone turnover markers (BTM), suPAR, interleukin 6 (IL6), TNFa, high-sensitivity C-reactive protein (hsCRP), lipid density profiling and lipid particle size. - Dual energy X-ray absorptiometry (DXA) of hip, lumbar columna, visceral and subcutaneous fat is measured by Hologic Discovery scanner.
The prevalence of diabetes has been growing rapidly in developing countries causing a devastating economic burden and increasing demands on healthcare systems. Therefore, there is an urgent need to find cost-effective and multi-faceted approach for diabetes care. Peer support models provide a potentially low-cost, flexible means that is complimentary to the current existing health care services. Trained peer leaders can become qualified extenders to a formal healthcare system, thereby, assisting with the education delivery and bolstering the efforts of the professional staff. To implement a culturally- specific peer support program and determine whether it is acceptable, cost-effective in China is important. This study aims to implement and evaluate biophysical and psychosocial outcomes of a peer support program and to explore it's feasibility and sustainability in China
Obesity is increasing all over the world in adults, adolescents and children,and is followed by morbidity, including the metabolic syndrome. Hypothesis: Among obese adolescents there is a subgroup with impaired glucose homeostasis The aim of the study is to identify adolescents with impaired glucose metabolism, 12-18 years, among high risk diabetes prone population, for diagnosis and treatment.
