Active clinical trials for "Diabetes Mellitus"

Doppler sonography provides an easily applicable, non-invasive, and well-established method for investigating renal morphologic characteristics and measuring vascular resistance in the renal parenchyma. Doppler are of strategic importance in providing qualitative and quantitative information about the renal vasculature, which can be obtained through the assessment of the resistive index.

The purpose of this study is to clarify the relationship between n-3 PUFA and irisin in regulating the glucose metabolism in GDM patients.

The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) aims to contribute with relevant information regarding the development and progression of clinical and subclinical chronic diseases, particularly cardiovascular diseases and diabetes. The investigators enrolled 15,105 civil servants from predefined universities or research institutes. Baseline assessment (2008-2010) included detailed interviews and measurements to assess social and biological determinants of health, as well as various clinical and subclinical conditions related to diabetes, cardiovascular diseases and mental health. For the ascertainment of incident events, annual telephone surveillance is being conducted since 2009, and a second visit of interviews and exams is under way (2012-2014). Long-term biological sample storage is provided for sera, plasma, urine and DNA. Baseline data is available for analyses, and collaboration via specific research proposals directed to study investigators is welcome. This multicenter study is chaired by a steering committee, made up of the coordinators and vice-coordinators of each of the six centers. No individual center coordinates the study. The six institutions listed in the contact details all sponsor the study.

Stress hyperglycaemia is commonly observed during hospitalization in the intensive care unit (ICU) and has been shown to adversely influence outcome. It has been hypothesized that, when it occurs in previously non-diabetic patients, it reflects a latent disturbance of the glucose metabolism. Assessing the incidence of this phenomenon and identifying its risk factors could support prevention, detection and early treatment of impending diabetes mellitus type 2. We will perform a glucose tolerance test approximately 6-9 months post-ICU admission to screen for disorders of glucose metabolism. Furthermore, we examined characteristics that could have predicted the post-discharge disturbances: patient characteristics, parameters of disease severity and of glucose metabolism, as well as the FINDRISC (Finnish Diabetes Risc Score). We plan to enroll 400 patients.

It has been hypothesized, based on recent trials, that only early intervention can reduce cardiovascular morbidity and mortality in individuals with type 2 diabetes (T2DM). This finding may imply that atherosclerosis at diabetes diagnosed, is either negligible, or at early, or non-advanced, still modifiable disease stage. However, sparse information is available regarding atherosclerosis prevalence and its characteristics at diabetes presentation. Furthermore, although cardiovascular disease (CVD) prevention is the major goal of treatment in T2DM, risk assessment tools, mostly based on traditional CV risk factors, lack of adequate specificity to identify individuals at higher risk. Therefore, non-invasive tests, such as carotid ultrasound, have been recommended to better define CV risk in several groups of individuals, including those with intermediate risk or with T2DM. This clinical study aims to improve the investigators knowledge on cardiovascular disease (CVD) in subjects with newly diagnosed T2DM (NEWDM). The investigators hypothesis is that carotid ultrasound (carotid intimae media thickness [CIMT] and carotid plaque [CP]) will show a worse subclinical/preclinical CVD stage in NEWDM compared with non-diabetic (CONTROL) individuals. Moreover, carotid ultrasound will also identify T2DM individuals at a higher risk in whom intervention should be more intensive. Because individuals with T2DM have a higher prevalence of several CV risk factors, NEWDM will be matched with CONTROL individuals, not only for age and sex (the main determinants of atherosclerosis), but also for known, treated hypertension and dyslipidemia, and smoking habit. The investigators will study NEWDM and CONTROL individuals without clinical CVD. This is a cross-sectional and longitudinal (18 months of follow-up) case-control study. The main study variables will be carotid ultrasound derived variables. The main aims of the study are: 1) to investigate CIMT and CP prevalence differences between NEWDM and CONTROL subjects; 2) to characterize the subset of NEWDM subjects with a higher CIMT (≥ mean+1SD o ≥ P75th) or CP presence; and 3) to early characterize individuals in whom subclinical CVD worsens (CIMT progression ≥ mean + 1SD o ≥ P75th) even after standard (according to clinical guidelines) diabetes treatment.

Type 1 diabetes results from the autoimmune destruction of the insulin-producing beta cells of the islets of Langerhans of the pancreas. Initially, diabetes is usually clinically silent with immune cells invading the pancreatic islets, a process termed insulitis, which eventually leads to loss of beta cells in the islets. If enough beta cells are destroyed, the body can not make enough insulin to maintain blood sugars in the normal range and clinical diabetes develops. The purpose of this study is to assess the ability of magnetic resonance imaging with ferumoxytol to detect changes in the pancreas associated with the insulitis of type 1 diabetes.

This study is a cooperative project and aims to identify genetic components associated with type 2 diabetes mellitus (T2DM), which is significant for the population of non-aboriginal Taiwanese.

The purpose of this study is to compare corneal endothelium morphology and central thickness in type II Diabetes Mellitus and normal subjects with special reference to glycemic status.

The purpose of this study is to evaluate the correlation among magnetocardiography (MCG) patterns and various known cardiovascular risk factors.
