Rare and Atypical Diabetes Network
Diabetes MellitusDiabetes Mellitus Progression5 moreRADIANT is a network of 14 clinical sites and several laboratories dedicated to the study of atypical diabetes. The objective of this study is to define new forms of diabetes and the unique mechanisms underlying these forms of atypical diabetes. The specific aims are to: Identify and enroll individuals and families with undiagnosed rare and atypical forms of diabetes. Determine the etiologic basis of the metabolic disorder among individuals and families with novel forms of rare and atypical diabetes. Understand the pathophysiology of individuals and families with novel forms of rare and atypical forms of diabetes.
The Relationship Between Diet and Glycemic Response and Inflammatory Markers in Children With Cystic...
Cystic FibrosisGlucose Metabolism DisordersThe aim of this study is to determine the relationship between diets of children with cystic fibrosis and glycemic responses and some inflammatory markers.
CBD, Nutrient Metabolism and Energy Intake
Glucose Metabolism Disorders (Including Diabetes Mellitus)Lipid Metabolism Disorders1 moreCBD may affect metabolic control and energy intake. However, there is currently little data regarding these specific outcomes in humans. Therefore, this study will investigate whether a single 300 mg dose of CBD can improve metabolic control following a meal and/or reduce energy intake at a subsequent meal. Healthy, adult volunteers will complete two conditions in a crossover design, comparing outcomes following both CBD and placebo supplementation.
Predicting Dysglycemia in Individuals With Gestational Diabetes Immediately Postpartum Using Continuous...
Gestational DiabetesPrediabetes; Complicating Pregnancy5 moreGestational diabetes is one of the most common medical disorders in pregnancy and is a major risk factor for the postpartum development of dysglycemia. Despite the high risk of developing dysglycemia, 50-80% of women with gestational diabetes are not receiving testing within a year postpartum. The investigators will conduct a prospective cohort study to examine the use of continuous glucose monitoring immediately postpartum to estimate the risk of maternal dysglycemia postpartum.
Brain Metabolism Observed at 7 Tesla
Glut1 Deficiency Syndrome 1Glucose Metabolism Disorders6 moreThe goal is to develop methodology to monitor flux in the citric acid cycle in brain via 13C nuclear magnetic resonance (NMR) spectroscopy at 7 Tesla.
Glucose Variability and Cognition in Prediabetes
Glucose Metabolism Disorders (Including Diabetes Mellitus)Cognitive Decline4 moreThis study examines the association of variability in glucose values over a 10-day period with cognitive function and functional status among individuals with prediabetes, aged 50 or older.
Hormonal and Inflammatory Changes During Pregnancy in Women With Glucose Metabolic Disorders.
Diabetes MellitusType 27 moreThe first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.
Mechanisms Behind Severe Insulin Resistance During Pregnancy in Women With Glucose Metabolic Disorders...
Diabetes MellitusType 27 moreThe aim of this study is to describe the metabolic changes during pregnancy in women with type 2 diabetes or gestational diabetes in order to detect the pathophysiological mechanisms behind severe insulin resistance during pregnancy as well as the short- and long term consequences for mother and child. Included pathophysiological mechanisms potentially associated with severe insulin resistance are: Maternal hormonal, inflammatory and metabolic markers in the blood, as well as the level, content and bioactivity of exosomes and genetic variants associated with overweight and diabetes. In addition to the analysis on maternal blood, the same analysis will be performed on umbilical cord blood in order to determine the correlation between markers associated with insulin sensitivity in maternal and umbilical blood. Furthermore, fetal metabolic changes influence on fetal growth and development will be evaluated. Postpartum, the breast milk will also be examined for metabolic active substances that could influence the newborns growth and metabolism. Investigating one potential short-term consequence of diabetes during pregnancy, the association between insulin resistance and structural and functional changes in the placenta will be examined as well as the consequences of such changes on fetal growth and development. Investigating one potential long-term consequence of diabetes during pregnancy, the association between treatment with high doses of insulin during pregnancy and the future risk of developing cardiovascular diseases and heart failure will be examined.
Support-t Online Training in Youth Living With Type 1 Diabetes Transitioning to Adult Care
Diabetes MellitusDiabetes Mellitus6 moreThe investigators will conduct a randomized controlled trial (RCT) to examine how an online training and peer support platform could help the preparation to transition to adult care. Among 14-16 year old youth with Type 1 Diabetes (T1D), the investigators aim to assess the effect of an online training and peer support platform (Support-t) integrated in usual care, compared with usual care on Hemoglobin A1c (HbA1c), adverse outcomes and psychosocial measures during the preparation for transition to adult care. The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority RCT of adolescents with T1D (14-16 years of age) followed at one of 4 university teaching hospital-based pediatric diabetes clinics in the province of Quebec.
Relationship Between Individual Effect of Diet on Postprandial Glycemia and Gut Microbiome Profile...
Glucose Metabolism DisordersHealth Behavior2 moreWhen all the food we eat is digested, it will increase blood glucose. Two people can have different glucose blood levels to the same food and one reason can be bacteria live in our gut. There are more than a thousand bacteria species in our gastrointestinal tract that have an important role in the proper functioning of our body, so our gut microbiome is a key piece for our nutrition and blood glucose control. Nowadays, one of the major public health concerns is the rise of people with diabetes (a disease characterized by an increase in blood glucose) and the increase in obesity, in which one of several risks is diabetes. There are multiple reasons for people develop those diseases, however, some care on diet management can prevent, delay, or improve the effects of these illnesses. Therefore, this study proposes studying the blood glucose variation between healthy volunteers and if there is a relationship between that variation and the intestinal bacteria present. These results can help doctors and nutritionists elaborate a personalized diet for people who need blood glucose level control. The investigators are recruiting volunteers aged 18 to 60, healthy, living at Florianópolis and the surroundings to participate in this crossover randomized N-of-1 study. The participants must collect fecal samples. After collection, the participants will meet the investigators and receive a kit containing ten standardized breakfasts, with two kinds of muffins, and a kit containing a glucose monitor (Abbott Freestyle Libre-CE marked) to monitor their blood sugar levels. The volunteers must have breakfast with the standardized meals and monitor the fasting glucose blood and postprandial glucose blood levels (two hours after the breakfast ingestion) for ten consecutive days. Besides, they must take notes (like a diet diary) about all the food they ingest during the day in ten days of the study.
