Filter by:Objective - Type 2 uncontrolled diabetic patients often have low endogenous melatonin and suffer from sleep disorders. The effect of a prolonged-release melatonin (PRM) formulation on glucose lipid metabolism and sleep is studied in type 2 diabetes patients with insomnia.
The hypothesis is that patients with poorly controlled diabetes would have greater improvement in their blood sugar control when managed by a clinical pharmacist than when managed with usual medical care. Patients with poor control are randomized to pharmacist management or to usual medical care for one year.
The objective of this study is to evaluate the effectiveness of Virtual Lifestyle Management (VLM) as a behavior modification tool to promote weight loss, healthy eating and physical activity patterns, in the interest of reducing risk and adverse outcomes for individuals at high risk of type 2 diabetes (T2D) and cardiovascular disease (CVD) in a military population. Specific Aim: To evaluate the effect of VLM on cardiovascular risk status in participants at high risk or individuals with T2D enrolled in the pilot study. The investigators hypothesize that participants will show greater improvement in weight as well as glucose, blood pressure, lipids, and self-reported diet and physical activity than will similar patients who are not enrolled in VLM.
The central hypothesis in the present project is that general anesthesia may alter autonomic control such that perioperative coronary blood flow (CBF) is significantly disturbed. These disturbances in coronary blood flow may contribute to the development of myocardial ischemia in the perioperative period. Furthermore, patients with an intrinsically altered autonomic sympathetic innervation, like diabetics, are even more prone to develop perioperative disturbances in coronary blood flow. Here the researchers will investigate what the direct effects are of general and locoregional anesthesia on the CBF. Furthermore, the researchers aim to evaluate whether diabetic subjects show more disturbed CBF responses to anesthesia as compared to non-diabetics.
The purpose of this study is to evaluate the benefits and risks of lixisenatide (AVE0010), in comparison to placebo, as an add-on treatment to basal insulin with or without sulfonylurea, over a period of 24 weeks of treatment. The primary objective is to assess the effects of lixisenatide, when added to basal insulin, on glycemic control in terms of glycosylated hemoglobin (HbA1c) reduction at Week 24. The secondary objectives are to assess the effects of lixisenatide on body weight, 2-hour postprandial plasma glucose (PPG) after standardized meal challenge test, percentage of patients reaching HbA1c less than 7 percent (%), percentage of patients reaching HbA1c less than or equal to 6.5%, fasting plasma glucose (FPG), change in 7-point self-monitored plasma glucose (SMPG) profiles, change in daily basal insulin and total insulin doses; to evaluate safety, tolerability, pharmacokinetics (PK), and anti-lixisenatide antibody development.
This study is conducted in Europe. The aim of this observational study is to evaluate glycaemic control in subjects with type 2 diabetes using once daily Levemir® as initiation of insulin therapy in Hungary.
The purpose of this study is to assess the performance of the subcutaneous glucose sensor over an extended sensor life. The sensor is currently approved for 3 days of use and this study will examine sensor safety and accuracy when used for six days. This study will also test sensor safety and accuracy when inserted in an alternate body location (buttock area in addition to abdomen area). The study hypothesis is that the sensor performance will not greatly diminish when used for six days, or in an alternate insertion area.
Insulin lispro and regular human insulin are Food and Drug Administration (FDA)-approved medications for the treatment of diabetes mellitus. Recombinant human hyaluronidase (rHuPH20) is approved by the FDA as an aid to the absorption and dispersion of other injectable drugs. In this study, rHuPH20 will be co-administered with both insulin lispro and regular human insulin in order to determine if it improves the absorption of these insulins to more closely mimic the body's natural increase in insulin in response to a meal.
Background: - Vitamin E is an antioxidant that reduces the damaging effects of oxygen in the body. Most American men (90%) and women (96%) do not get enough vitamin E from their diets; however, the amount of vitamin E needed by the body has been studied only in men, not women. In addition, it is unknown whether another antioxidant, vitamin C, helps vitamin E in protecting the body. Because vitamin E is a fat-soluble vitamin, how much body fat a person has could affect the amount of vitamin E needed for protection. Objectives: This study has three arms to examine vitamin E requirements: - To determine the amount of fat required to get the best vitamin E absorption from a meal. - To determine the amount (i.e., best dose) of vitamin E that must be consumed before it can be measured in the blood. - To examine how vitamin E and vitamin C work together in the body, in conjunction with diet and vitamin supplements. Eligibility: - Arms 1 and 2: Women between the ages of 18 and 40 years who have a normal weight and body mass index (BMI) of 27 or less. - Arm 3: Women between the ages of 18 and 40 years who have a normal weight (BMI 27), who are overweight (BMI > 27), or who are overweight (BMI > 27) and have non insulin-dependent diabetes. Design: - Arm 1: Five studies, each lasting 1 month with 1 month off between studies (total study = 10 months). Participants will take 500 1,000 mg of vitamin C twice daily for 2 weeks before admission to the clinical center for 1 week. - Study 1: Participants will eat breakfast containing a known amount of fat, after which they will take a vitamin E pill as well as receive an IV injection of vitamin E. Other foods contain only negligible amounts of vitamin E. Blood and urine samples will measure levels of vitamin E and other substances. - Studies 2 5: Outpatient visits will consist of the same tests as in Study 1; however, the amount of fat in the breakfast will range from 0% to 40% in random order. During one of the studies, an adipose tissue biopsy will be collected to determine how much vitamin E is in the tissues. - Arm 2: Five studies, each lasting 1 month with 1 month off between studies (total study = 10 months). Preparation for Arm 2 is the same as in Arm 1. The proportion of fat, muscle, and water in the body will also be measured. - Study 1: Participants will eat breakfast containing 30% fat, after which they will take a vitamin E pill as well as receive an IV injection of vitamin E. Conditions and procedures are the same as in Arm 1. - Studies 2 5: Outpatient visits will consist of the same tests as in Study 1; however, the amount of vitamin E in the breakfast will range from 2 to 30 mg in random order. - Arm 3: Outpatient (2 to 6 weeks) and inpatient studies (4 to 6 weeks). - Outpatient study: Participants will take 500 1,000 mg of vitamin C daily and provide blood and urine samples, as well as an adipose tissue sample. - Inpatient studies: Two vitamin E inpatient studies. Before these begin, participants vitamin C blood levels will be reduced by means of a diet low in vitamin C. Blood tests will determine how quickly vitamin C leaves the body. Once the vitamin C level is reduced, the first vitamin E study will begin. Study A: The procedure for this study is the same as in Arm 2, Study 1. Study B: The procedure for this study is the same as in Study A, except that the participants blood vitamin C levels will be higher.
The purpose of this study is to determine the efficacy of switching to a combination tablet ezetimibe/simvastatin (10mg/20mg) versus rosuvastatin (10 mg) versus doubling the statin dose in those patients who have cardiovascular disease and diabetes mellitus not adequately controlled on simvastatin 20 mg or atorvastatin 10 mg.
