Active clinical trials for "Diabetes Mellitus, Type 2"

Type 2 diabetes its microvascular and macrovascular complications have become a major global health problem. Metformin is often used as first-line therapy for this disorder given that it is cheap, may cause weight loss and does not have significant side-effects in healthy patients. On the other hand, as many as one third of all patients with type 2 diabetes initially treated with metformin never achieve a meaningful response to this intervention. Recently, genetic variation in the organic cation transporter 1 (Oct1) gene which encodes a protein, OCT1, mediating metformin uptake by the liver, its primary site of action, has been shown alter metformin action. In Oct1-deficient mice the glucose-lowering effects of metformin are completely abolished. Moreover a polymorphism with a 20% minor allele frequency in Caucasians also alters the effect of metformin on glucose tolerance (the net result of glucose uptake and glucose release) after ingestion of 75g of glucose. However, it is unknown if this polymorphism affects suppression of endogenous glucose production or stimulation of peripheral glucose uptake by metformin, or both, and to what degree. We propose to utilize established methodology to measure glucose turnover in response to a mixed meal to determine how common genetic variation in OCT1 alters response to metformin in healthy volunteers. This will clarify the effect of these variants on response to metformin in humans. The knowledge gained from this study will help to design future studies examining the role of OCT1 genotype in determining initial therapy for type 2 diabetes.

We will test an NCD intervention bundle incorporating the World Health Organisation (WHO)'s Package for Essential Non-Communicable Disease Interventions (PEN) within an approximate population of 300,000 people in rural Nepal. This intervention integrates three evidence-based approaches for both facility- and community-based NCD care focused on the key areas of Clinical Practice, Counseling, and Technology for two tiers of non-physician healthcare worker - Mid-Level Providers and Community Health Workers: 1) Task-shifting of evidence-based medicine algorithms and clinical skills from PEN protocols to non-physician healthcare workers; 2) Delivering quality counseling based on the Motivational Interviewing Model to drive behavior change with respect to both treatment adherence (defined as medication adherence and follow-up completion) and risk factor modification (alcohol, tobacco, diet, physical activity); 3) Employing a facility- and community-based clinical decision support tool for effective integration of PEN protocols into non-physician healthcare worker workflow. This five-year study will initial test the acceptability and feasibility of the intervention (two years) followed by a type 2 hybrid effectiveness-implementation research trial (three years) to which we will apply the RE-AIM implementation evaluative framework of both outcomes and process indicators. Co-primary outcomes for the intervention bundle will be: a) disease-specific, evidence-based control metrics that measures clinical efficacy; b) qualitative evaluation of acceptability and feasibility that incorporates perspectives of patients, providers, and government stakeholders; and c) an implementation checklist of key intervention process measures.

The proposed study aims to provide preliminary data that will enable the conduct of a larger Randomized Controlled Trial (RCT) on the impact of bilingual Prescription Medication Labels (PMLs) on 3 medication-related outcomes - medication adherence, medication management self-efficacy, and PML understanding.

Ghrelin is a hormone naturally produced in the stomach and the gut. The purpose of this research study is to determine the role of this gut hormone in the regulation of insulin secretion from the pancreas and glucose disposal after we eat. The investigators hypothesize that ghrelin has an effect on the pancreas and on how our body handles glucose after we eat. The investigators will compare insulin secretion and glucose changes during meal ingestion while either acyl ghrelin (AG) or saline (salt solution) is being infused through your vein on separate study days. AG is a form of the ghrelin hormone that has a small modification to it that allows it to bind to a specific receptor. The investigators hypothesize that AG has an effect on how the body handles glucose after a meal. AG has been approved by the U.S. Food and Drug Administration (FDA) for human research only. This study will also involve the use of a medicine called arginine, which is a naturally occurring product and found in many nutritional supplements. Its use in this study is investigational. The use of arginine helps maximize insulin release from the pancreas so the investigators can better examine whether AG affects insulin secretion.

In an unbiased metabolomics approach with subsequent pathway analyses, the current study seeks to examine the effect of Liraglutide treatment on the metabolic signature in treated patients as well as the effect of Liraglutide on various echocardiographic parameters of cardiac function and rhythm profile, thus paving the way for future research to explain the effects of Liraglutide on cardiovascular mortality and overall mortality in treated patients.

Adult cardiac surgery ensures the surgical treatment of valvular and coronary pathologies and of heart failure with the placement of ventricular assistance. Extracorporeal circulation (ECC) is one of the major technical advances associated with cardiac surgery to replace cardiac and pulmonary functions during surgery. ECC can nevertheless lead to postoperative complications, the origin of which is linked to the patient's initial contact with the circuit and membranes of the ECC. This contact triggers a series of humoral and cellular reactions that occur in the first few hours after the ECC and the inflammatory syndrome post ECC fades on its own and usually disappears between the 4th and 6th postoperative day. If the inflammatory response post ECC is most often transient, certain conditions will maintain and intensify this response at the origin of postoperative complications, possibly leading to the patient's death. Among these situations, the investigators find the notion of emergency cardiac surgery, a patient's age over 75 years and a preoperative history of decompensated heart failure, renal failure or type 2 diabetes (T2D). The inflammasome family of receptors of the nucleotide oligomerization domain (NOD) type, pyrin domain containing 3, NLRP3, is a multi-protein platform of recent discovery which plays a major role in the signaling pathways of the innate inflammatory response. The role of the activation of the NLRP3 inflammasome in cardiovascular pathologies is now well established and its metabolic priming by hyperglycemia could explain the greater seriousness of these pathologies in T2D patients due to an exacerbated inflammatory response. What is the effect of T2D status on the inflammatory response post ECC, mediated by the NLRP3 inflammasome, in patients after cardiac surgery?

Outcomes in type 2 diabetes are largely achieved by self-management efforts by individuals living with diabetes. Diabetes self-management is typically provided using the principles of adult education. Current evidence suggests that standard educational interventions are suboptimal. This study evaluates a novel approach to diabetes self-management using dialogue tools based on empowerment and motivational communication methods. The approach evaluated in this study is called EMMA: empowerment, motivation and medical adherence. Participants will be randomized to EMMA and treatment as usual, treated for a period of 4 months and evaluated over a period of 12 months.

Physical activity (PA) is recommended for the treatment of subjects with type 2 diabetes to increase insulin sensitivity and improve metabolic control. However, adherence to PA is often poor, due to a lack of motivation or due to disabling complications or comorbidities. Neuromuscular electrostimulation (NMES) is a physical treatment commonly used to improve muscle strength and volume in several situations: after stroke, after limb trauma or during chest rehabilitation in deconditioned patients. The investigators have already shown in a first pilot study (manuscript in preparation) that NMES improves insulin sensitivity : in the study ELECTRODIAB (No. ID-RCB: 2011-A00930-41), the investigators showed a 25% insulin sensitivity improvement after a week of daily 25-min bi-quadricipital NMES session, in a population of patients with orally-treated type 2 diabetes. Insulin sensitivity increased up to 50% in the most deconditioned subjects. Discrepancy between this result and the very low energy expenditure measured during sessions suggests that the metabolic effect was not solely mediated by muscle contractions. The investigators hypothesize the involvement of neurological pathways. Indeed, it is demonstrated that the autonomic nervous system is an important regulator of glucose metabolism with pancreatic action, a key role in energy metabolism and a complex relationship with insulin resistance. Muscle activity, whether static (isometric) or dynamic causes changes in sympathetic nerve activity in healthy subjects but its effect in type 2 diabetic subjects is not known. The investigators hypothesize that, in type 2 diabetic subjects, the modulation of sympathetic nerve activity by NMES could be involved in the improvement of insulin sensitivity. To address this question, the investigators propose to assess sympathetic nerve activity with the gold standard method of microneurography before and after a single bi-quadricipital NMES session. The impact of neuro-electro-stimulation (NES) (a sensitive stimulation under muscular threshold) and the impact of voluntary isometric muscle contractions (VC) will also be evaluated. These procedures will also be applied in healthy control subjects.

The study will be conducted in participants with type 2 diabetes on insulin injection therapy to investigate how the body processes a test formulation of insulin lispro and the effect of the test formulation on blood sugar levels. Side effects and tolerability will be documented. The study will be conducted in two parts (Part A and Part B) to achieve its objectives. Participants are expected to enroll in both parts.

The aim of our study was to investigate the effect of sole sensation on peripheral muscle strength, functional capacity, balance and physical activity level in individuals with Type 2 Diabetes Mellitus.
