Filter by:Normoglycemia is important for the outcome of surgical and medical conditions. Insulin infusions have been studied to achieve normoglycemia during these circumstances and have proved to be useful. Insulin given by subcutaneous injections has longer duration compared to intravenous given insulin which makes it more difficult to control. The hypothesis behind the trial is the concept that insulin infusion is more effective in reaching normoglycemia in diabetic subjects during treatment for ulcer infections and/or planned cardio-vascular surgery. - The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during ulcer infection and after cardio- vascular surgery. - Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.
The purpose of this study is to investigate the effects of chronic elevated levels of Prolactin on metabolism and insulin sensitivity by studying patients with hyperprolactinemia before and after treatment.
The present study on pharmacological intervention in autonomic nervous dysregulation(parasympathetic dysfunction,) regarding insulin resistance, is a concept testing in humans tohelp identify potential new pharmacological target sites in the central nervous system.
The influence of insulin sensitivity and glucose tolerance on the effects of antiviral therapy for HCV remains unclear. The aim of the present study was (1) To elucidate the clinical and virological factors associated with sustained viral response in patients with combination therapy with PEG-IFN and ribavirin. (2) To clarify the influence of diabetes mellitus (DM), impaired glucose tolerance test (IGT) and insulin resistance (IR) on the HCV response to combination therapy with PEG-IFN and ribavirin. (3) To test the influence of combination therapy on HOMA IR
This study investigates the degree of improvement in insulin resistance and features of the metabolic syndrome in non-diabetic overweight or obese subjects after training in a low-intensity, moderate-intensity or non-aerobic exercise program, as well as self-initiated exercise behavior after the assigned exercise program.
The purpose of this study is to investigate the effect og chronic elevated levels of cortisol on metabolism and insulin sensitivity.
Gestational diabetes (GDM) is a condition that manifests as high blood sugar levels (hyperglycemia) during pregnancy in previously healthy women. It develops as a result of increased maternal body's resistance to insulin - a major hormone that allows for utilisation of glucose (sugar taken in with food) within cells. It was found out that GDM occurs more frequently in overweight women but also in women with a history of certain conditions such as polycystic ovary syndrome (PCOS). Usually, GDM disappears after pregnancy is completed but it is associated with some serious hazards for women and her unborn child, if untreated properly. Diet is a first-choice treatment but sometimes insulin therapy must be initiated if keeping a diet alone is not enough to maintain blood sugar within recommended values. Insulin therapy is effective but it requires several injections during each day and insulin is a strong acting hypoglycemic agent that may induce rapid falls in blood sugar, also dangerous for mother and unborn child. In the investigators study, the investigators would like to investigate if metformin that is a commonly used hypoglycemic drug can be effectively used for GDM treatment. Metformin has been used successfully for a long time to treat type 2 diabetes mellitus and PCOS and, according to current data, it is not dangerous neither for mother nor for baby when used during gestation.
The goal of this research study is to study the effect of testosterone or estrogen on blood sugar control and fat metabolism. Changes in hormone levels with age may affect risk factors for heart disease such as diabetes. Diabetes is a glandular condition associated with lack of the hormone insulin or an insensitivity to it resulting in problems with blood sugar control and fat metabolism. The effect of commonly used hormonal supplements such as testosterone by older adults on insulin and body composition is not well understood. In this study, the role of testosterone and estrogen on your ability to control blood sugar and your body composition will be assessed. We plan to study 60 subjects. All of these subjects will be healthy older men between the ages of 60-85 years old who are not on testosterone therapy. Subjects that are screened who have any clinically significant abnormalities detected on their screening physical exam or laboratory testing (e.g. PSA > 4), who have a history of prostate cancer, polycythemia, or who cannot take testosterone will not be included. If a subject is eligible to participate after initial screening, that subject will take medications to adjust their hormone levels and have tests performed that measure insulin sensitivity and adiposity before and after these hormone medications. The outcomes that will be measured are: 1) insulin sensitivity, 2) hormone levels (total and free testosterone levels, sex hormone-binding globulin levels) and 3) body composition and abdominal adiposity.
The main purposes of this study are to find out if the study drug losartan (Cozaar) or placebo ("sugar pill") has an effect on insulin sensitivity (how your body responds to insulin) and to measure the effect of the study drug losartan or placebo on how the arteries in your arm dilate (enlarge to carry more blood). We hope to learn if taking losartan changes the amount of certain proteins in the blood that effect blood vessel function. Losartan is approved by the US FDA to treat high blood pressure. It will take approximately 4 months for you to complete this study.
Many hospitalized patients who are malnourished or not eating receive intravenous feeding or total parenteral nutrition (TPN). Despite improving nutrition, TPN may increase the risk of infections and hospital complications. We do not know why TPN increases hospital complications, but it may be caused by the high sugar or fat content in TPN solutions.
