Impact of Peer Support on Diabetes in China
Glucose Metabolism DisordersMetabolic Diseases2 moreThe prevalence of diabetes has been growing rapidly in developing countries causing a devastating economic burden and increasing demands on healthcare systems. Therefore, there is an urgent need to find cost-effective and multi-faceted approach for diabetes care. Peer support models provide a potentially low-cost, flexible means that is complimentary to the current existing health care services. Trained peer leaders can become qualified extenders to a formal healthcare system, thereby, assisting with the education delivery and bolstering the efforts of the professional staff. To implement a culturally- specific peer support program and determine whether it is acceptable, cost-effective in China is important. This study aims to implement and evaluate biophysical and psychosocial outcomes of a peer support program and to explore it's feasibility and sustainability in China
The Influence of Overfeeding Different Macronutrients on Whole-body Insulin Sensitivity
Insulin ResistanceType 2 Diabetes2 moreThis study will investigate the effect of high-carbohydrate vs. high-fat overfeeding (130% of energy requirements) on whole body insulin sensitivity. Following habitual diet, participants will be randomly allocated to either a high-carbohydrate or a high-fat diet intervention for 14-days. On days 0, 7 and 14 participants will undergo anthropometric and metabolic testing (primarily an oral glucose tolerance test [OGTT]).

PrediabetesMetabolic Diseases3 moreThe purpose of this study is to determine whether the freshwater clam extract and its combination is effective on the improvement of glucose and lipid metabolism, also evaluate its ability to postpone prediabetes patients to become diabetes.
Canderel:Effects on Blood Glucose Concentration and Appetite Scores
Appetitive BehaviorGlucose Metabolism DisordersThis study investigates the effects of Canderel, an aspartame and acesulfame-k blend artificial sweetener powder, on post-postprandial blood glucose levels and appetite scores.
Metabolic and Genetic Impacts of Energy Drinks in Youth
NutritionPediatric Obesity6 moreCaffeine containing energy drinks (CCED) are beverages that typically contain mixtures of simple sugars, caffeine and may contain vitamin, mineral and/or herbal preparations. In Canada, the consumption of CCEDs among adolescents is a regular occurrence and a common part of the everyday diet. Contributing to the obesity epidemic in youth is the consumption of energy drinks; yet no data on the metabolic responses to CCEDs exists. This study will examine the metabolic implications of CCED consumption in adolescents, aged 13-19 years. The investigators hypothesize that CCEDs will impair glucose tolerance by ~30% in lean adolescents and the primary cause of the insulin resistance will be caffeine. Obese individuals will experience a similar level of glucose impairment, but a greater rise in blood glucose compared to their lean counterparts (i.e. higher starting glucose level). For many, this additional, caffeine-induced rise will expose them to hyperglycemia, putting some individuals in the glucose intolerant or transient diabetic range. It is hypothesized that continued metabolic insult resulting from CCEDs may predispose susceptible individuals to chronic metabolic diseases later in life. The investigators will also examine the genetic basis of caffeine-induced glucose intolerance. This gene-diet interaction could explain why caffeine may be much more metabolically harmful for some individuals compared to others. The study of 'metabolomics' will also be utilized to analyze caffeine and caffeine metabolites such as theobromine, theophylline, and xanthine. This will be accomplished using Nuclear Magnetic Resonance (NMR) spectroscopy. Results from this study will have the potential to alter current perceptions that CCED are 'harmless' and will have far reaching implications for both medical professionals and legislators alike.
Hormonal and Metabolic Aspects of Endoscopic Sleeve Gastroplasty
Endoscopic Sleeve GastroplastyLaparoscopic Sleeve Gastrectomy2 moreThe investigators of the study want to investigate the complex interactions between glucose metabolism, food intake/weight loss, and different appetite regulating hormones after ESG in comparison with conventional laparoscopic sleeve gastrectomy (LSG).
Gestational Diabetes Mellitus and Neurodevelopment in Newborns
DiabetesGestational1 moreThe purpose of this study is to evaluate the feasibility of using a quantitative EEG method to evaluate neurodevelopment in newborns and to evaluate whether subtle neurodevelopmental deficits can be detected in newborns from mothers with gestational diabetes mellitus (GDM) compared to control newborns. The second purpose of this study is to determine whether cord blood concentration in docosahexaenoic acid (DHA), an omega-3 fatty acid, is similar in neonates of well-controlled mothers with gestational diabetes mellitus (GDM) compared to control mothers, and to evaluate whether this contributes to neonates neurodevelopment status.
Investigating Genetic Risk for Type 1 Diabetes
Diabetes MellitusType 16 moreThe objective of this study is to determine the percentage of children with genetic markers putting them at increased risk of developing type 1 diabetes, and to offer the opportunity for these children to be enrolled into a phase II b primary prevention trial.
Change of Glucose Metabolism and Fibrosis Markers in Patients With Hepatitis C Under Treatment With...
Glucose Metabolism DisordersLiver Fibrosis1 moreChronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. This might be a additional risk factor for disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis.
