Active clinical trials for "Diabetes Complications"

The purpose of this study is to evaluate the effects of multiple dose regimens of relamorelin on vomiting episodes, gastric emptying and gastroparesis symptoms in participants with Type 1 and Type 2 diabetes mellitus and gastroparesis. Study drug (relamorelin and placebo) will be administered subcutaneously in a blinded fashion.

The objective of this study is to examine the feasibility of using a collaborative-care, home-based rehabilitation program to improve functional outcomes for people recovering from lower limb amputation caused by vascular problems and/or diabetes complications. The primary hypothesis is that the rehabilitation program will result in greater improvements in performance-based and participant-reported measures of physical function, compared to standard of care after outpatient rehabilitation.

The purpose of this study is to determine if subthreshold vibration, when applied to the residual limb of a lower limb amputee through their prosthetic socket, can sufficiently enhance peripheral sensation to result in an improved ability to balance and walk.

Diabetes Mellitus (DM) is a global epidemic associated with inflammation, aggressive atherosclerosis and increased risk for, and severity of, coronary artery disease. Strategies to improve glycemic control with insulin and/or oral hypoglycemic agents have not impacted cardiovascular morbidity and mortality in type II DM patients with known heart disease. The Investigators have found that the typical "Western" diet, which is high in saturated fats, such as the lipid palmitate, but low in unsaturated fats, such as the lipid oleate, results in changes to cell membrane lipid content and disruptions to membrane functional domains -called caveolae- that are associated with insulin resistance and metabolic dysfunction. In mice, the investigators found that palmitate induces both systolic and diastolic contractile dysfunction. They have demonstrated, in cell cultures, that oleate prevents palmitate-induced cell dysfunction. This may explain how a diet rich in unsaturated fats and plant-derived flavonoids, such as the "Mediterranean" diet, can counter the adverse cardiovascular effects of DM. This study builds in these prior findings and its central hypothesis is that, in DM, a Mediterranean diet can induce rapid changes in cardiac cell membrane lipid composition and signaling. This is a randomized dietary intervention in DM subjects scheduled for coronary artery bypass grafting (CABG) surgery, to examine the effects of a short-term modified Mediterranean diet (ModMeD), compared to the standard cardiac DM diet (SCaDMD), on receptor tyrosine kinase signaling, serum and cellular lipid content, and membrane/caveolae function.

This study will examine the effect of oral thiamine (Vitamin B1) supplementation on pain in patients with diabetic peripheral neuropathy.

Type 1 diabetes (T1D) is a lifelong disease which stops the body from producing insulin - an important hormone that controls blood sugar (glucose) levels. People with T1D use insulin replacement therapy, usually in the form of injections, to help control blood glucose levels, however keeping glucose levels within normal ranges is usually a challenge. Mealtime glucose control is fundamental to good diabetes management and are an important contributor to long-term diabetes complications. However, many individuals experience variability in glucose levels around mealtimes. The objective of this study is to establish whether and which parameters are important predictors of mealtime glucose levels in people with T1D. The investigators will monitor glucose levels using the latest glucose monitoring technology and collect blood samples to: Characterise changes in glucose levels in individuals with T1D in response to different meals Determine whether and what food characteristics and personal factors are linked to individual glucose responses to different meals. The investigators will recruit 150 individuals with type 1 diabetes. Firstly participants will attend a preliminary visit, where a blood sample will be donated to study laboratory blood markers of vascular and metabolic health accompanied by a full medical examination in which body composition will be established. During this visit participants will also complete questionnaires about their lifestyle, and be fitted with two wearable devices to monitor glucose levels and physical activity levels under free-living conditions. After 4-weeks of wearing the devices, participants will attend two experimental laboratory visits where breakfast and lunch will be served and blood samples taken. This will enable us to observe glucose and metabolic responses to feeding under controlled conditions.

We will perform blood sugar studies to assess changes in metabolic (biochemical processes that occur within us) profiles associated with high blood sugar and diabetes.

This particular trial is looking to compare the effectiveness of two types of foot bed/ sole materials used within diabetic footwear.

The objective of the project is to evaluate advantages from the use of a bearable continuous interstitial glucose monitoring device (GuardianR) during educative sessions of diabetic patients dedicated to functional insulin therapy teaching. This concept of intensified treatment is based on testing and explanation of simplified decision making algorithms to adapt insulin dose to every true life conditions. As self monitoring of capillary glucose level is needed to validate those algorithms, we postulate that using a device able to permanently control interstitial glucose readable by both medical team and patient himself (during the session and the 5 following days after discharge) could significantly improve safety and efficiency of such educative session.

Over 1.25 million Americans have type 1 diabetes (T1D), increasing risk for early death from cardiorenal disease. The strongest risk factor for cardiovascular disease (CVD) and mortality in T1D is diabetic kidney disease (DKD). Current treatments, such as control of hyperglycemia and hypertension, are beneficial, but only partially protect against DKD. Hyperfiltration is common in youth with T1D, and predicts progressive DKD. Hyperfiltration is also associated with early changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure. Intrarenal hemodynamic function is strongly influenced by the renin-angiotensin-aldosterone system (RAAS), which is also considered a key player in the pathogenesis of DKD. Preliminary data demonstrate differences in intrarenal hemodynamic function and RAAS activation in early and advanced DKD in T1D. However, the pathophysiology contributing to the differences observed in RAAS activation and intrarenal hemodynamic function in T1D are poorly defined Animal research demonstrates that arginine vasopressin (AVP) acts directly to modify intrarenal hemodynamic function, but also indirectly by activating RAAS. Preliminary data suggest that elevated copeptin, a marker of AVP, which predicts DKD in T1D adults, independently of other risk factors. However, no human studies to date have examined how copeptin relates to intrarenal hemodynamic function in early DKD in T1D. A better understanding of this relationship is critical to inform development of new therapies targeting the AVP system in T1D. Accordingly, in this study, the investigators propose to define the relationship between copeptin and intrarenal hemodynamics in early stages of DKD, by studying copeptin levels, renal plasma flow, and glomerular filtration in youth (n=50) aged 12-21 y with T1D duration < 10 y.
