Filter by:Diabetes mellitus is one of the chronic non-communicable diseases which have emerged as a leading global health problem. According to the International Diabetes Federation Atlas guideline report, currently, there are 352 million adults with impaired glucose tolerance who are at high risk of developing diabetes in the future. In 2017, it was estimated that 425 million people (20-79 years of age) suffered from Diabetes mellitus, and the number is expected to rise to 629 million by 2045. Moreover, Egypt is considered one of the top 10 countries in the world
Type 1 diabetes mellitus is a chronic autoimmune disease, associated with an increased risk of cardiovascular diseases. The development of cardiomyopathy in type 1 diabetes, independent of hypertension and coronary heart disease, is still controversial. A possible mechanism for diabetic cardiomyopathy is autonomic dysfunction. This study aims to evaluate cardiac function and structure, and to relate them with autonomic dysfunction in type 1 diabetes.
According to data of the International Diabetes Federation (IDF), diabetes in general affects approximately 415 million people worldwide and this number is still increasing. Cardiovascular diseases, one of the major complications of diabetes, are the leading cause of mortality and morbidity in the diabetic population. One of the cardiovascular complications is diabetic cardiomyopathy, in which structural and functional changes occur in the heart impairing cardiac function. Exercise training has already proven the benefits on glycemic control in diabetes. This is also the case for the effects on cardiac function. However, as results are conflicting, it remains unclear which elements of exercise training should be focused on. For instance, high-intensity interval training (HIIT) is gaining interest as positive effects are already shown on glycemic control. Therefore, the potential of HIIT to improve cardiac function in diabetes should be investigated. Further on, the effects of exercise training on cardiac function are mainly investigated during rest by the use of transthoracic echocardiography. Therefore, as data are lacking, it remains unclear how the diabetic heart functions during exercise. The aim of the present study is to investigate the effects of different training modalities (e.g. HIIT) on heart function in diabetes both during rest and during exercise itself. Therefore, cardiac function will be evaluated by the use transthoracic (exercise) echocardiography. This will be combined by the evaluation of several biochemical parameters. The results will provide more insight in the pathology of diabetic cardiomyopathy as well as the potential of exercise training for this cardiovascular complication. Eventually, this research will contribute to the optimization of exercise programs for patients with diabetes.
The coverage of the diabetes is a multidisciplinary care, with practitioners' implication(hospital and liberal), and other medical and paramedical profession: doctor, pharmacist, male nurse, nutritionist, etc. In fact there is a real importance of link between hospital and general medecine outside. That's why the pharmacist's presence during the hospitalization seems to be a good alternative to make the link between hospital and the outside pharmacist where patient take his treatment. Hospital pharmacis proceed to a treatment conciliation at the entrance and at discharge. By this conciliation the aim of the study is to show and quantify the impact of pharmacist presence on therapeutic target .
It has been suggested that mitochondrial dysfunction might play a role in the development of diabetic cardiomyopathy. From animal studies, it has been suggested that an altered PPAR and PGC1 expression is involved in the reduced cardiac mitochondrial function, however human data on cardiac mitochondrial function and PPAR regulation is scarce. The latter is due to the fact that there is no validated measurement for assessing cardiac mitochondrial function non-invasively in vivo. It has been suggested that measuring PCr/ATP ratio with 31P-MRS in the heart reflects cardiac mitochondrial function. However, so far no direct validation of this method has been performed. The aim of this study will be to validate in vivo 31P-MRS with ex vivo measurements of mitochondrial function. To this end, the hypothesis is that in vivo 31P-MRS is a valid method for measuring cardiac mitochondrial function when compared with ex vivo mitochondrial respirometry.
Pathophysiology of diabetic cardiomyopathy (DCM) is yet unclear and gender differences at baseline and a specific treatment have not been indicated. The investigators already demonstrated the positive impact of phosphodiesterase type 5A (PDE5A) inhibition in men. The investigators' study aims to characterize DCM, measuring molecular and neuroendocrine assessment to relate to intramyocardial metabolism and cardiac kinetic. The investigators will perform a randomized, placebo-controlled, double-blind study enrolling 164 diabetic patients (females and males) with DCM, to evaluate gender responses to 6 months of PDE5A inhibitors (PDE5Ai). The investigators' study will describe gender differences in DCM features. The proposed research will test whether PDE5Ai could become a new target for antiremodeling drugs and to discover a molecular pathways affected by this class of drugs and a network of circulating markers for the early diagnosis, monitoring and prediction of response to treatment of DCM.
The goal of this study is to determine if nutritional therapy can effectively treat/prevent T2DM and its consequent cardiomyopathy.
The overall purpose of this study is to evaluate the effect of gastric bypass surgery-induced weight loss on the heart's function and on fat deposits in the heart muscle.
