Active clinical trials for "Diabetes Mellitus"

Diabetes mellitus (DM) plays an important role in the occurrence of the cerebral infarction (CI). Clinical studies have demonstrated that the CI patients with DM had a poor prognosis compared with those without DM. Previous magnetic resonance imaging (MRI) studies have shown that patients with DM had abnormalities in cerebral vessels, nerves and functions, similar with the findings in mice models. In this study, with multi-modal MRI technologies, investigators tend to observe structural and functional changes of the brain in both DM and non-DM CI patients and assess their neural rehabilitation using clinical scales in the following 6 months. Investigators also expect to find out dynamic changes of brain structure and function, to reveal the weights of factors including brain blood vessels, nerves and function remodeling related with stroke recovery, as well as the potential mechanism in CI patients with DM.

The purpose of the study is to determine whether glycemic control (HbA1c) is linked to chromosomal damage in type 2 Diabetes patients

By analyzing the relationship between the body constitution and the progression of Type II diabetes mellitus, its morbidities, mortality and the impact of the life quality, we try to provide an useful tool, body constitution, to stratify the patients accordingly for individualized health care.

After having had a first cardiovascular event, there is a considerable risk of developing a subsequent event. Only recently, a risk prediction model was developed for this group of patients. Imaging techniques such as the coronary artery calcium score and contrast-enhanced computed tomography (CT) of the coronary and carotid arteries could be able to add improve this model. Imaging may further improve the prediction of future manifestations of arterial disease and personalize disease monitoring and treatment.

Pregestational diabetes (PGD) during pregnancy may be associated with an increased rate of spontaneous abortions, intrauterine death and congenital anomalies among the offspring. Although the prevalence of congenital anomalies among the offspring of diabetic mothers is reduced as a result of the improvement of the glycemic control in the early pregnancy, the rate of congenital anomalies is increased and there seems to be an increased rate of neurodevelopmental disorders including some fine and gross motor deficits as well as increased rate of inattention and/or hyperactivity. In gestational diabetes, that develops in the second half of pregnancy (past the period of major organogenesis), there seems to be no increase in the rate of major congenital anomalies but there are some developmental disorders in the offspring. The exposure of the developing embryo and fetus to diabetic environment (i.e. hyperglycemia, hyperketonemia ext), is known to cause increased oxidative stress and significant changes in gene expression as observed in several experimental diabetic models. We hypothesize that diabetic environment may also cause long lasting epigenetic changes. It is therefore our purpose to evaluate these possible epigenetic changes and correlate their presence with the degree and time of onset of diabetes, (i.e. whether from the beginning as in PGD or in the second half of pregnancy as in GD), the degree of oxidative stress and with the neurodevelopmental outcome of the offspring. Diabetic pregnancies will be compared to a similar number of normal pregnancies in all parameters studied.

High risk population: Screening for impaired glucose tolerance.

This study will expand the understanding of factors associated with adherence to self care and the diabetes control among diabetes type 2 patients. The theoretical framework of the study incorporates central variables from two theoretical models: a cognitive model of health behavior - "Health Belief Model", and the Stress and Coping model. The study is innovative in its focus on the association between the patient's attachment style and adherence to self care and diabetes control, a topic less studied among diabetes patients, in addition to cognitive, social and emotional variables. Further emphasis is upon a comparison of the study model between males and females.

In Type 2 Diabetes mellitus patients we will: quantify vasculopathy and blood-retinal barrier (BRB) leakage measure blood-brain barrier (BBB) permeability and neuroanatomical changes correlate BRB pathology with BBB breakdown, inflammatory markers and neuropsychiatric sequela

It has been observed that several of patients having prolonged or complicated course of acute viral hepatitis have underlying diabetes. It is possible that with impaired hepatocyte regenerating capacity, these patients run a more prolonged and complicated course. We hypothesize that acute hepatitis infection has a prolonged and complicated course among diabetic patients.

The primary objective of this study is to identify whether cardiovascular complication rates are lower in patients who participate in managed diabetes care, in comparison to provincial and national rates. This study will involve an electronic medical record (EMR) chart audit, augmented by a manual review of hospital and other pertinent medical records, as necessary.
