Filter by:This randomized, double-blind, placebo-controlled study will assess the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of RO5095932 in patients with type 2 diabetes mellitus. Patients will be randomized to receive either RO5095932 subcutaneously once weekly or placebo for 4 weeks (part 1) or 6 weeks (part 2), in addition to their current stable doses of metformin.
This trial is conducted in Europe. The aim of this clinical trial is to evaluate the variability in the blood glucose-lowering effect of NN1250 (insulin degludec) in subjects with type 1 diabetes.
The purpose of this study is to test whether vitamin K supplementation has an effect on glucose metabolism in terms of acute beta cell response.
This research project is designed to investigate endotoxin (a toxin present in the wall of certain kinds of bacteria) levels and the type of bacteria present in the intestine before and after Roux-en-Y gastric bypass or gastric banding surgery in patients that meet the classification for morbid obesity (body mass index >40 kg/m2) and type 2 diabetes. It is known that the type of bacteria present in the intestines of normal weight and obese individuals are different, and it is also known that people with obesity and type 2 diabetes have higher levels of endotoxin. It has been shown that the bacteria change over the long run after Roux-en-Y gastric bypass surgery, but the short-term effects are not known and the endotoxin levels after this procedure have never been studied.
The purpose of this study is to investigate the pharmacokinetics and pharmacodynamics of sitagliptin in healthy volunteers.
Sensory input from the foot as well as all other body parts results in activation of sensory cortex. It is well known that the cortical body map is experienced-dependant and can rapidly change in response to changes in activity and sensory input from the periphery [10-12]. Increased activity and sensory input from the hand results in expansion of the cortical hand representation [13-15], while decreased sensory input, for instance by anaesthesia, amputation or nerve injury, results in shrinkage of the cortical hand representation [16-21]. Due to the constant ongoing "cortical competition" between body parts the adjacent cortical areas expand and take over the silent area, deprived of sensory input. The investigators have recently described striking examples of such rapid cortical re-organisations induced by selective cutaneous anaesthesia of the forearm: application of EMLA cream to the volar aspect of the forearm results in improved sensory functions of the hand [18] linked to expansion of the hand representational area in sensory cortex . In analogy, EMLA application to the lower leg in healthy controls results in improved sensory functions in the sole of the foot linked to expansion of the foot representational area in sensory cortex. To test the hypothesis that EMLA application to the lower leg of diabetic patients will result in improved sensory functions in the sole of the foot as well as expansion of the foot representation in sensory cortex. The investigators hypothesize that repeated applications of EMLA will result in a long lasting sensibility improvement.
This trial is conducted in Asia. The aim of this clinical trial is to investigate the bioequivalence of repaglinide and metformin combination tablet versus repaglinide and metformin as coadministered tablets after meal. The trial is designed as a three-period, six-sequence, single-dose, crossover pharmacokinetic trial where the trial participant is randomised to one of six possible treatment periods (Williams design). The trial participant will receive one single dose of each trial product in varying order.
Pancreatic Islet beta-cells are responsible for synthesizing and secreting appropriate amounts of insulin to regulate blood glucose levels. One factor in the development of diabetes is the loss of beta-cells. Developing treatments to prevent or restore islet beta-cell mass (BCM) in diabetic patients is hampered by a lack of methods for the non-invasive imaging of these cells. This study is designed to evaluate a radiolabeled compound that binds to the pancreatic islet. The investigators will test the ability of one promising imaging compound, 18F-9-fluoropropyl-(+)-dihydrotetrabenazine (18F-FP-DTBZ), to measure the amount of pancreatic islet beta-cells in patients with long-standing type-1 diabetes and in age-weight-matched healthy control subjects.
Little is known about the long-term health and mental health status of women Vietnam veterans. For many of these women, the effects of this war are still present in their daily lives. As these women approach their mid-sixties, it is important to understand the impact of wartime deployment on health and mental health outcomes nearly 40 years later. The investigators propose to assess the prevalence of posttraumatic stress disorder (PTSD) and other mental and physical health conditions for women Vietnam veterans, and to explore the relationship between PTSD and other conditions and the Vietnam deployment experience. The investigators are interested in studying women Vietnam veterans who may have had direct exposure to traumatic events. For the first time, the investigators also want to study those who served in facilities near Vietnam. These women may have had similar, but less direct exposures. This cross-sectional study will seek to contact approximately 10,000 women for participation in a mailed survey, telephone interview and a review of their medical records. Women identified as serving in Vietnam, near Vietnam (in Asia during the Vietnam Ware) and in the U.S. during the Vietnam War will be identified from an established cohort and sent a survey on demographics, behaviors, disability, health-related quality of life, and medical conditions. Women agreeing to be contacted will also be interviewed by study investigators using the modified CIDI to ascertain current and lifetime mental health conditions (including PTSD) and exposure to traumatic events. A more extensive chart review will be conducted by a clinician to validate self-report of key medical conditions.
This study will examine changes in various gut-derived hormones in obese type 2 diabetic patients before and after elective bariatric surgery.
