Filter by:The purpose of the study is to compare the effect of adding alogliptin, once daily (QD), to the ongoing treatment regimen of pioglitazone HCl and metformin in patients with inadequate glycemic control.
A couple of studies have shown that illuminating the eye with diffuse flickering light is accompanied by an increase of retinal vessel diameters, optic nerve head blood flow and retinal blood flow. We have recently used this visual stimulation technique as a new and powerful tool for the non-invasive investigation of vascular reactivity. Additionally, we could show that this response is diminished in patients with vascular pathologies and that the response is dependent on nitric oxide, indicating that flicker induced vasodilatation may reflect endothelial dysfunction and may be a new approach to test endothelial function in vivo. One of the most widely used method for the assessment of endothelial function is flow mediated dilatation (FMD). FMD has been shown to give a reliable estimate of vascular function in vivo. In the present study, we set out to compare the standard method for the evaluation of endothelial function, FMD, to flicker induced vasodilatation in the retina.
The purpose of this study is to evaluate the prevalence and clinical predictors of subclinical coronary atherosclerosis and to validate the usefulness of coronary CT angiography as a screening tool in asymptomatic patients with type 2 diabetes mellitus.
The purpose of this study is to compare the difference of diagnostic efficiency between coronary CT angiography and myocardial perfusion single photon emission computerized tomography in asymptomatic patients with type 2 diabetes mellitus.
Aim: To investigate the quality of history taking by physician and computer-based system. Patients: 100 inpatients presenting at the RBK for the first time and treated in the departments of nephrology and cardiology. Methods: The information obtained by the computer based system is compared with the information acquired by conventional history taking. Study endpoint is the comparison of historical data organized according to the elements in a standard medical history on a patient-by-patient basis. Study procedure History taking is performed by physicians according to the guidelines of the RBK. Within 2 days thereafter the patient is interviewed with help of the CLEOS system with the support of a study nurse.
Previous scientific research has found multiple genes that affect the risk for developing heart disease or complications during the treatment of heart disease. Less is currently known about how patients with heart disease may differ on the basis of other ailments they may have and how these other ailments may affect their treatment and prognosis. For this reason, researchers at the Mid America Heart Institute are conducting this research to find out how genes affect heart disease and recovery following angioplasty. The study will include patients with diabetes in order to determine if their genes are different from patients without diabetes. A total of 1,607 patients were enrolled. There were 2 groups of patients selected for this study. The first group of patients included into the study will be those that are scheduled to have a diagnostic angiogram only. The second group of patients were those that had along with the angiogram a percutaneous transluminal coronary angioplasty, PTCA and or the use of a device called a coronary "stent", designed to help prop open the artery and to help avoid collapse. Samples for both groups will be stored for 30 years. After this time, all samples will be destroyed. Ultimately, we are hopeful that we will identify genes that will identify groups of patients at risk for heart disease.
The study is designed to investigate the effect of 18 weeks treatment with Sitagliptin 100 mg/day on the insulin secretion capacity of beta cells. Patients who meet the study enrollment criteria will undergo 2 experiments (see description below); a graded hyperglycemic technique and a meal test, prior to randomization and after a 12-wk double-blind study period. The treatment effect will shed light on the magnitude of the beta cell capacity to increase its mass and function.
FGF-1 is being used for the treatment of patients with diabetic or venous stasis ulcers. Procedure includes topical administration of FGF-1 or placebo and evaluation of safety, pharmacokinetics, and wound improvement.
The purpose of this study is to determine if rosiglitazone treatment improves integrated cardiovascular performance in patients at risk for congestive heart failure. A second aim of this study is to determine if treatment with rosiglitazone decreases intracellular (ectopic) triglyceride (TG) deposition in cardiomyocytes using nuclear magnetic resonance (NMR) techniques, and how changes in intra-myocardial lipid content relate to changes in cardiac structure and function.
To determine, in subjects with Type 1 Diabetes Mellitus: 1. Whether glycemic control can be achieved at least as effectively with an insulin regimen involving pre-meal inhaled insulin plus a single bedtime Ultralente injection as with a conventional subcutaneous insulin regimen involving 2-3 mixed Regular/NPH insulin injections per day. 2. The toleration and safety of inhaled insulin therapy and its effects after 6 months, if any, on measures of pulmonary function.
