Filter by:Exogenous ketone supplements are proposed to have glucose-lowering potential, provide an alternative fuel for the brain and to enhance cognitive function. No studies have tested whether exogenous ketones can lower blood glucose in people with type 2 diabetes. In addition, the impact of exogenous ketones on brain blood flow, cognitive function or brain-derived neurotrophic factor in humans is unknown. The purpose of this study is to determine if acutely ingesting exogenous ketones, in the form of a ketone monoester drink, can lower glucose and improve measures of brain/cognitive function in humans with type 2 diabetes. Participants will consume a ketone monoester drink or placebo with blood samples, brain blood flow, and cognitive function assessed over 180 minutes. The researchers will also test how the ketone monoester drink impacts appetite and measures of inflammation.
The Study of Sulphonylurea Synergy with DPP4 Inhibitors (SSS Study) will establish whether a very low dose of sulphonylurea will have a synergistic role on augmentation of insulin secretion when given in combination with a DPP4 inhibitor as a primary outcome. The study will recruit 30 patients with type 2 diabetes mellitus controlled with no treatment or metformin monotherapy with an HbA1c <64mmol/mol (<8%). In this unblinded, randomised physiological study, participants will receive four 14-day intervention blocks: low dose sulphonylurea alone, DPP4 inhibitor alone, low dose sulphonylurea + DPP4 inhibitor or no treatment change. The primary outcome will be assessed through evaulation of insulin secretion and sensitivity at mixed meal test at the end of each treatment block. Glycaemic variability on continuous glucose monitoring for each intervention block will be evaluated as a secondary outcome. In addition, the primary outcome will be evaulated for KCNJ11 genotype as an additional secondary outcome.
The incidence of atrial fibrillation (AF), the most common heart rhythm disorder, is increasing. The symptoms of AF include: unpleasant heartbeats; difficulty breathing; tiredness; dizziness; and, reduced exercise capacity. Patients with AF have lower quality of life, higher mental distress, and higher risk of heart disease and stroke when compared to the general population. Further, patients with non-permanent AF tend to experience more severe symptoms and substantial reductions in quality of life when compared to patients with permanent AF. Type 2 diabetes increases the risk of developing AF and accounts for about 20% of patients with non-permanent AF. High blood glucose concentrations and increased blood glucose fluctuations (large and frequent upward and downward blood glucose swings) are commonly seen in type 2 diabetes. Increased blood glucose fluctuations may worsen AF symptoms and quality of life in patients with AF. Exercise improves quality of life and mental health and reduces risk of developing heart disease and stroke. However, no clinical guidelines for managing AF include exercise. High-intensity interval training (HIIT), a form of exercise that alternates between intense bouts of exercise and less intense recovery periods, is a time-efficient approach to improve blood glucose fluctuations in type 2 diabetes. In healthy individuals and in patients with coronary artery disease, HIIT also improves quality of life and mental health. Currently, the effect of HIIT on blood glucose fluctuations, AF symptom severity and quality of life in patients with AF living with type 2 diabetes is unknown. Also, the links between blood glucose fluctuations and AF symptom severity and quality of life have not been investigated.
Women post-gestational diabetes mellitus (GDM) have more than 7-fold increased risk of having future type 2 diabetes mellitus (T2DM). While a healthful dietary pattern reduces the risk of diabetes in post-GDM, no data support a dietary pattern tailored to the Malaysian diet. To address this issue, the investigators propose to determine the effects of dietary patterns and plasma metabolites in predicting the risk of T2DM known as the Nutritype model. The aim of this study is to identify Nutritype signatures of T2DM risk in women post-GDM using metabolomics approach.
Patients with type 2 diabetes (T2D) suffer from an excess risk of adverse cardiovascular events. Recently, two classes of glucose lowering agents, namely SGLT-2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP-1RA), have proved superior to placebo in protecting T2D patients from cardiovascular events in dedicated trials. Patient populations in such trials were mainly composed of T2D individuals with established cardiovascular disease (CVD) or at very high risk for CVD. In addition, no clinical trial has so far compared cardiovascular outcomes of T2D associated with SGLT2i versus GLP-1RA. In addition, whether different results would incur in patients at lower CVD risk is unclear. On this basis, we designed this retrospective real-world study to compare cardiovascular outcomes of patients newly treated with SGLT2i versus GLP-1RA in routine clinical practice
Diabetes is an independent risk factor for ischemic heart disease (CAD) and heart failure, and cardiovascular diseases are the main cause of mortality and morbidity in patients with diabetes. Recent studies on cardiovascular outcomes have shown that type 2 sodium glucose co-transporter (SGLT-2i) inhibitors are not only effective in improving glycometabolic control, but are also able to reduce major CV events (MACE) and hospitalization for heart failure. However, it is still unclear whether the beneficial CV effects of treatment with SGLT2i are due to indirect mechanisms such as reduction in blood pressure, improvement of vascular stiffness, reduction in body weight and visceral adiposity, reduction in uricemia or whether they have effects direct on the heart. Recently, it was shown that in nondiabetic porcine model with heart failure, the treatment with empagliflozin was associated with a switch of myocardial fuel utilization from glucose uptake toward uptake of ketone bodies and free fatty acid, thereby improving myocardial energetics, enhancing LV systolic function, and ameliorating adverse LV remodeling. It is not known whether empagliflozin treatment is able to modify the heart's energy metabolism even in humans. In this study we hypothesize that empagliflozin may determine beneficial CV effects reducing myocardial metabolic rate of glucose assessed by hyperinsulinemic euglycemic clamp 18F-FDG PET scans in patients with type 2 diabetes. This is a single-center, prospective, controlled, randomized, open-label, two parallel group and switch, active-comparator study that evaluates the comparative effects of 26 weeks of treatment with empagliflozin versus glimepiride add on metformin on myocardial metabolic rate of glucose estimated through 18F-FGD-PET scan in patients with type 2 diabetes without a history of coronary heart disease. At the end of 26 weeks of treatment, subjects belonging to the first group will be shifted to glimepiride therapy, while subjects belonging to the second group will be shifted to empagliflozin treatment for 26 weeks. All subjects, then, will control themselves.
The Investigators previously developed pulsed electromagnetic field stimulation therapy (PEMF) for the metabolic activation of muscle and adipose tissues. In vitro and in vivo preliminary data from rodents demonstrate that PEMF-t induced changes reminiscent of beneficial exercise adaptations, in response to enhanced metabolic fuel utilisation. These exercise mimetic effects were achieved in the absence of exercise and its associated mechanical stresses as the rodents were sedentary. A human pilot study conducted with this platform demonstrated improved muscle function after only 5 weeks. The PROMISE pilot trial will investigate whether metabolic activation of muscle with a novel, non-invasive technology will further improve metabolic outcomes in overweight/obese patients with early T2DM who are currently given diet and/ or lifestyle interventions.
The objective of this protocol is to answer the questions: 1) Within food supplementation options, are mailed stock boxes superior to food vouchers in terms of achieving glycemic control? 2) Is the combination of mailed stock boxes and food vouchers superior to either food supplementation option alone? 3) Does providing diabetes education in combination with food supplementation lead to improved clinical outcomes compared to education alone? To address this gap in the literature, we propose a randomized controlled trial to test the separate and combined efficacy of monthly food vouchers to farmers market and monthly mailed food stock boxes layered upon diabetes education in improving glycemic control in low income, food insecure, AAs with Type 2 Diabetes (T2DM) using a 2x2 factorial design.
The study investigates the regulation of muscle glucose utilization during exercise and enhanced insulin sensitivity in recovery from exercise. This will be investigated in lean control subjects and obese insulin resistant subjects.
Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are an injectable, non-insulin therapy for patients with type 2 diabetes (T2D). Semaglutide (Ozempic®) is the newest GLP-1 RA to become available in Canada in 2018, and is administered subcutaneously once-weekly. In clinical trials, semaglutide has been superior to placebo and other antihyperglycemic agents in HbA1c reduction and body weight loss. However, there is little real-world evidence available on the effectiveness of semaglutide in real-world clinical practice. To better understand the effectiveness of semaglutide on clinical outcomes in a real-world setting, this retrospective cohort study will use the Canadian LMC Diabetes Registry to examine the effects of semaglutide on glycemic control, body weight, and other clinical outcomes in patients with T2D who initiate once-weekly semaglutide as part of usual clinical care in a diabetes specialist practice group in Canada.
