NCT03019510
Morning hyperglycemia plays a role in the future development of insulin resistance and type 2 diabetes (T2D) (8) and is associated with numerous microvascular and cardiovascular complications and renal disease. These augmented morning glucose levels are due to an elevated endogenous glucose production (EGP), as a result of a loss of coordination between glucose levels and insulin secretion, and possibly hyperglucagonemia during the overnight period. Exercise stimulates glucose uptake and increases insulin sensitivity acutely, and may be the best lifestyle intervention to minimize the nocturnal rise in glucose levels. Prescription of the timing of exercise relative to a meal and/or to the overnight period may be particularly critical for individuals that have impaired fasting glucose (IFG) levels. Surprisingly little is known about the overnight period when elevated EGP and the synchrony between glucose and c-peptide/glucagon levels becomes disturbed. This novel study will provide insight into the hormonal/metabolic milieu of a dinner meal, the evening and overnight period that occurs in non-obese, OB and OB+IFG individuals; it will also establish if the timing of exercise can attenuate nocturnal glucose elevations, and if this is associated with improved hormonal synchrony. This project will compare EGP, β-cell function and hormonal responses between morning and evening exercise on the postprandial and overnight period in obese individuals with/without IFG levels. Fifty-four subjects will be studied during the evening meal (EGP and β-cell function), postprandially and through the overnight period (1600-0700 h), allowing us to examine some of the potential mechanisms for the elevation in overnight glucose levels. This is the first study that will examine this issue from pre-dinner through the night while previous studies have only examined chronically fasted individuals and this study will lay the groundwork for understanding the pathology of the predawn phenomena in OB+IFG individuals. These potentially translational findings may impact the efficiency of physician communication to patients concerning exercise. These investigators are one of the few groups that study subjects through the overnight period and have the facilities and capability to do this research.
NCT04238494
Frailty is a multideterminant syndrome in which muscle function appears to play a central role. Muscle function depends on brain control, nutrition and perfusion. We hypothesized that multiparametric MRI assessment combined with comprehensive gerontological assessment (CGA) and routine biological assessment of inflammation in a sample of older people with and without diabetes will allow to explore on one side the possibilities of multi-parametric MRI muscle and brain imaging to describe the correlates of frailty and on the other side will describe the different muscle/brain alterations due to diabetes in frailty. The main objective is to compare the lipid percent of the rectus femoris in frail and pre-frail older subjects and in non-frail older subjects.
NCT01880827
Obesity is a worldwide problem and leads to multiple metabolic and endocrinological problems. Bariatric surgeries are a growing field as a treatment choice for morbid obesity (BMI \> 35 kg/m2). Clinical and research evidence shows that shortly after RYGB, T2DM resolves with improving glucose tolerance. Foregut hypothesis behind bariatric surgeries postulate, that bypassed portions of intestine contain a substance, that acts as an anti-incretin, ie. to counteract metabolically favourable incretins. In view of the recent studies, it may be that GIP is really the anti-incretin behind this hypothesis. The current study is conducted to investigate the vasoactive roles of the GIP. The investigators aim to show that GIP is the major contributor to the blood flow and tissue blood volume observed in postprandial state.
NCT02772679
The purpose of this study is to assess the safety of Tregs + IL-2 and survival of Tregs in patients with recent onset T1DM who receive infusions of autologous Tregs + IL-2.
NCT05083013
Coronavirus disease (COVID-19), a global pandemic affecting the whole world and taking the lives of millions. The majority of fatalities occur in the elderly specially in the presence of chronic diseases such as diabetes mellitus (DM), hypertension, obesity, cardiovascular disease, chronic kidney disease and cancer.
NCT03847701
This is a monocentric, randomized, single-blind and controlled study with a parallel design (2 arms). The research hypothesis is that the diet high in Slow Digestible Starch (SDS) content (H-SDS) will lower the daylong glycemic response and improve the glycemic control just as metabolic, inflammatory, cardiovascular and oxidative stress parameters in patients with type 2 diabetes (T2D) compared to the diet low in SDS content (L-SDS). The hypothesis is that these differences in glycemic response and in metabolic, inflammatory, cardiovascular and oxidative stress parameters response can be observed after 3 months of diet.
NCT03496298

NCT01843959
A cross-sectional study investigating the aetiology, mechanisms and associated complications contributing to obesity and diabetes within the UAE population. The study will be carried out in two main sample populations; children and adults, and characterized by the occurrence of obesity and diabetes. The main samples will then be divided into a subgroup for metabolomic analysis. Patients will be recruited from the Imperial College London Diabetes Centre. The study is aimed at elucidating the various factors that have an impact or may influence obesity and diabetes in the Emirati population.
NCT04499846
The objective of the study is to measure changes in compliance to statin therapy in patients with type 2 diabetes after an educational intervention. This intervention is part of the therapeutic education of the diabetic patient, carried out throughout the follow-up of his/her diabetes.
NCT03310502
Aim of the study is to investigate genes regulating glucose and lipid metabolism in subjects whose glucose metabolism, lipid metabolism, blood flow, or body fat distribution has been measured using positron emission tomography (PET), magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS) or computed tomography (CT) as part of their previous participation in clinical trials conducted at Turku PET Centre. By combining information from PET, MRI, CT, proteomics, metabolomics and genetics analyses we aim to find connection between genetic variation and metabolic and cardiovascular disease.

Secondary Objective: 1. To access liver fibrosis progression/regression in CHC patients after sofosbuvir-based treatment. 2. To investigate the long-term outcomes of extrahepatic manifestations of the sofosbuvir-based treated cohort as compared to their pretreatment status.
NCT04263168
The diverse community of gut microbes commonly referred to as the 'gut microbiome', is increasingly suggested to play significant roles in health and disease, and to affect even distant non-GI organs by metabolite signaling. Type 2 diabetes mellitus (T2DM) patients feature a distinct gut microbiome signature4, while modulating the gut microbiome by either antibiotics or fecal microbial transplantation (FMT) is suggested to impact insulin sensitivity. Originally designed to treat obesity, bariatric surgeries often induce a robust and rapid weight-independent improvement in glucose homeostasis within days. Early diabetes remission following bariatric surgery is hypothesized to be mediated by rapid alterations in the gut microbiome and bile acids composition, however, the exact mechanism is yet to be uncovered. Elucidating this mechanism is important as it may form the basis of a new therapeutic modality in diabetes. The investigators intend to deeply characterize early post-bariatric changes in the gut microbiome of diabetic patients, as well as their gut mucosal transcriptome and metabolome, by using state-of-the-art experimental and computational pipelines. Additionally, The investigators will utilize a unique mouse model of bariatric surgery under germ-free conditions, developed at the Elinav lab, that allows us to dissect the role of microbes in post-operative metabolic improvements.
NCT05072587
African Americans (AAs) have a higher risk of developing type 2 diabetes than the general population. AAs are also more likely to eat foods that contain cholesterol oxides/oxysterols. Dietary oxysterols can harm the cells that produce insulin and decrease insulin production. This pilot study seeks to determine if removing dietary oxysterols with a plant-based diet will improve insulin production and decrease the risk of type 2 diabetes among AAs.
NCT02571608
Type II Diabetes Mellitus patients having surgery who adhere to their regular scheduled metformin dosing and take this medication on the morning of surgery will have better glycemic control peri-operatively and potentially suffer less morbidity compared to individuals taking a placebo.
NCT04340908
Patients with diabetes have poorer cardiac surgery outcomes compared with non-diabetics. Proper blood glucose management is critical to reduce the morbidity and mortality for diabetic patients after cardiac surgery. SGLT2 inhibitors including dapagliflozin as a new diabetes drug can reduce heart failure hospitalization rates and overall cardiovascular mortality in patients with cardiovascular disease. This study is to assess the impact of one year of treatment of SGLT2 inhibitors on cardiac function, postoperative complications and long-term cardiovascular mortality in diabetic patients undergoing cardiac surgery. The investigators use echocardiography to evaluated cardiac function in diabetic patients during perioperative cardiac surgery.
NCT04228003
The study is a single site, prospective, open label, observational, single arm trial in 30 patients with type 2 diabetes with GI complaints using 1 or more oral or injectable anti-hyperglycemic agents to investigate if altering the microbiome though Pendulum T2D dietary supplementation can further enhance the efficacy of the current treatment while reducing the GI associated symptoms in patients with Type 2 diabetes.
