Filter by:The primary objective is to investigate the effect of apple polyphenol supplementation for 12 weeks on glucose homeostasis in prediabetic individuals. Further, this study has three secondary objectives: 1) to investigate whether daily supplementation at breakfast and dinner with apple polyphenols for 12 weeks affects the rhythm of glucose uptake over the day and reduces fasting glucose levels and postprandial glucose peaks; 2) to determine the effect of daily supplementation with apple polyphenols for 12 weeks on biomarkers of metabolic health; 3) to assess whether daily supplementation with apple polyphenols for 12 weeks alters fecal SCFA concentrations and fecal microbiota composition.
Pre-diabetes is a state characterized by subclinical impairment in glycemic variables that is intermediate between normal glucose tolerance (NGT) and diabetes. There are two frequently used definitions for pre-diabetes, one from the American Diabetes Association (ADA) and another from the World Health Organization (WHO), and both include impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and a calibrated hemoglobin A1c (HbA1c) of between 5.7 and 6.4%. More than 30 % of the global population demonstrated one or more forms of prediabetic dysglycaemia. In general, approximately 70 % of individuals with IFG and/or IGT can expect to go on to develop clinical type 2 diabetes at some time in the future, and the risk increases with higher HbA1c levels and with higher BMI. Worse still, the prevalence of pre-diabetes is increasing worldwide, with a growing number of patients progressing to diabetes. Identification and treatment of pre-diabetic individuals is therefore crucial. Recent evidence suggested that preventing progression of pre-diabetes to diabetes is possible, and thus efficacious interventions for pre-diabetic individuals are the cornerstone of diabetes prevention. The current paradigm for diabetes prevention in high-risk individuals focuses on achieving moderate weight loss via dietary change and increasing physical activity. However, lifestyle-based weight-loss strategies may initially be successful, but difficult to achieve or maintain. In many cases, pharmacologic treatments may be needed to regulate blood glucose. Randomized clinical trials (RCTs) have verified the efficacy of metformin in preventing insulin resistance syndrome, along with the progression of microvascular diseases and heart attacks. Meanwhile, clinical experience and trial data have yielded almost no significant safety concerns for metformin. Nonetheless, it may cause discomfort for up to 25% of patients who experience diarrhea and nausea subsequent to its administration. For patients with a contraindication or intolerable adverse effects to metformin, Sodium Glucose Cotransporter 2 (SGLT-2) inhibitors with novel mode of action may be another alternative. Large clinical trials have not yet identified a substantial elevation in the frequency of adverse reactions related to SGLT-2 inhibitors when compared to the placebo group. Inhibition of SGLT-2 has some extra advantages for diabetes management over other therapeutic approaches. Firstly, the SGLT-2 is exclusively expressed in renal proximal tubules, and thus selective inhibitors will exert a glucose-lowering effect, independently of insulin secretion. Therefore, SGLT-2 inhibitors can cause weight loss without inducing major hypoglycemic events. Secondly, the cardiovascular benefits of SGLT-2 inhibitors was supported by large clinical trials in the modern context of antiplatelet, statin, and blood pressure management, which may match many of the advantages of metformin. Thirdly, SGLT-2 inhibitors have also been proven to prevent nephropathy for its restriction on albuminuria and inflammatory processes, and to subsequently dampen the deterioration in renal function. Overall, SGLT-2 inhibitors have demonstrated safety in non-diabetic patients, particularly in those afflicted with heart or kidney failure, and have shown to provide additional benefits. At present, the overall effectiveness and safety of SGLT-2 inhibitors in improving metabolism of pre-diabetic patients are still unclear. The purpose of this experiment is to evaluate the effect of SGLT-2 inhibitor on pre-diabetic patients.
The goal of this clinical trial is to learn about the alterations insulin resistance and metabolic flexibility following a transition to an obesogenic lifestyle in fit young men. The main questions it aims to answer are: 1. Does the addition of excess carbohydrates when transitioning to a sedentary lifestyle promote insulin resistance in fit young men? 2. Does the addition of excess carbohydrates when transitioning to a sedentary lifestyle lower the body's ability to break down fats and carbohydrates in fit young men?
The overall survival of acute lymphoblastic leukemia (ALL) and lymphoma in children and adolescents is above 90%. The survival rate has increased significantly during the last decades as a consequence of more intensive chemotherapy. This very toxic treatment results in severe acute toxicities and late effects, which is the biggest challenge today besides survival. The overall purpose of contemporary ALL treatment is to reduce the toxic treatment without compromising the excellent survival rates of these diseases. This study is a part of this. The researchers want to investigate the incidence of glucose intolerance and medicine induced diabetes during treatment for ALL and lymphoma with steroids (prednisolone or dexamethasone) and ± PEG-asparaginase. Steroids and asparaginase are used in the treatment of ALL and lymphomas, and both drugs may induce glucose intolerance or diabetes, especially when they are given concomitantly. The incidence and duration of increased blood glucose levels are not very well investigated, and especially not monitored continuously during treatment phases with steroids and +/- asparaginase, as the investigators want to do in this study. In the study the participants must have a glucose sensor attached under the skin, which continuously measures blood glucose during treatment. Moreover, blood samples are drawn several times to measure insulin sensitivity and beta cell function. The participants are children and adolescents (1.0-17.9 years) with newly diagnosed ALL or lymphoma treated at one of the four Danish pediatric oncology sites. Blood glucose levels are followed during treatment with steroids and PEG-asparaginase in these patient groups. The results may give rise to a new treatment guidelines for measuring and treating blood glucose in these patients. In the future this may help reduce the development of type 2 diabetes mellitus and metabolic syndrome in survivors of ALL and lymphoma.
This is a prospective, double blinded, randomised cross over feeding trial examine high or low FODMAP diet in combination with metformin on postprandial glucose responses and gastrointestinal tolerability and gut microbiota profiles. The trial will compare high or low FODMAP diet, each of 10 days duration in combination with 5 days metformin, separated by a washout period of at least 2 weeks.
The purpose of this study is to determine the short-term effect of a nutritional program consisting of a yerba mate supplement, fiber supplement, and intermittent fasting on glycemic variability in men and women with risk factors for impaired fasting glucose.
This study will examine whether a physical activity program, specifically increasing walking steps, offered over the internet is able to increase physical activity in adults with prediabetes. The study will take place over 12 weeks. The investigators want to see if people who receive the intervention increase their physical activity more than people who do not receive the intervention. The physical activity program will include using a pedometer to track daily step counts online, set weekly goals, and receive motivational messages delivered weekly using email. The investigators are also going to collect data on waist circumference, body weight and quality of life at baseline, 12 weeks and 16 weeks after the intervention has completed to see if these change over the course of the study. The investigators will be recruiting 200 adults who have attended the Edmonton, Alberta prediabetes education class offered by Alberta Health Services, Nutrition Services and report they have prediabetes. If able to successfully increase physical activity, this study will identify a web and home-based intervention that can be offered to individuals who participate in lifestyle programs delivered in primary care settings (e.g., Edmonton prediabetes program) in both rural and urban locations.
The incidence of type 2 diabetes (T2D) in children is increasing, paralleling the rising incidence of obesity. Preventing children and adolescents from developing T2D is critical. The health benefits of lifestyle modifications are well documented in this population, but success rates are low. Obesity in children and adolescents increases the risk of not only T2D but other complications as well, such as hypertension, dyslipidemias and more. The investigators hypothesize that having real-time glucose data with the use of a continuous glucose monitor (CGM) in obese patients with impaired glucose tolerance will improve adherence to lifestyle modifications. As a result, a decrease in body mass index (BMI) is expected with subsequent improvement in insulin sensitivity, thus reducing risk of obesity-related complications later in childhood/adolescence and adulthood.
The purpose of this study is to investigate the effects of a fibre mixture added to a high-protein diet on metabolic, gut and brain health.
