Sleep, Glycemic Control, and Insulin Resistance in Adolescents With Type 1 Diabetes
Type1diabetesAdolescent Behavior1 moreDespite advancements in care, most adolescents with T1D have higher BMI and significantly higher HbA1c than recommended and are markedly IR, placing them at increased risk for CVD1,2. Thus, alternative approaches to improve and maintain glycemic control, IR, and BMI for adolescents with T1D are urgently needed. This proposal moves beyond the current insulin and carbohydrate counting-focused lifestyle change paradigm to focus on sleep and circadian misalignment, which will allow for identification of new mechanisms that can be directly translated into future intervention and prevention trials. The goal of the current study is to utilize multiple objective measures of sleep duration, timing (actigraphy), and circadian rhythm (melatonin) in adolescents with type 1 diabetes (T1D; N = 40) and examine relationships with glycemic control, IR, vascular health, and BMI. Further, qualitative methodology will be used to identify barriers and facilitators to healthy sleep in adolescents with T1D.
The Salivary Microbiome in Children With Type 1 Diabetes Mellitus
Type1 Diabetes MellitusAims: To profile the oral microbiome of children with type 1 diabetes mellitus, and to compare it to healthy children while taking into account other aspects of the oral environment. Research: exploring the differences between oral microflora of children with type 1 diabetes mellitus and control healthy children using salivary microbiome. The investigators will furthermore intend to analyze the differences of salivary flow rate, pH, glucose, calcium, inorganic phosphate and urea between the two groups.
Plasma Dihydroceramides Are Associated With Hepatic Steatosis in Type 1 and Type 2 Diabetes
Diabetes MellitusType 22 moreSphingolipids are associated with metabolic diseases. Distribution of plasma sphingolipids in type 1 and type 2 diabetes has never been studied. The objective of the CERADIAB study is to compare plasma sphingoliplids concentrations in type 1 and type 2 diabetic patients.
Activation Innate Immune System in Type 1 Diabetes
Diabetes MellitusType 15 moreHyperglycemia is a well-known cardiovascular risk factor. It has also been shown that episodes of hyperglycemia increase the risk for cardiovascular diseases despite return to normoglycemia, a phenomenon termed 'glycemic or metabolic memory'. The molecular mechanism underlying this phenomenon remains unclear. Cardiovascular events, such as myocardial infarction and stroke are caused by atherosclerosis, which is characterized by low grade inflammation of the vascular wall, including accumulation of innate immune cells such as monocytes and macrophages. The investigators hypothesize that chronic hyperglycemia shifts intracellular metabolism of innate immune cells towards glycolysis and changes the epigenetic state of (progenitors of) innate immune cells (monocytes and macrophages), which reprograms these cells towards a more aggressive, pro-atherogenic phenotype, thereby accelerating atherosclerosis. In this study, the investigators aim to test this hypothesis. This research will reveal whether the innate immune cells of patients with chronic hyperglycemia show a durable shift in intracellular metabolism and epigenetic changes and whether this associates with vascular inflammation.
Biomarkers in Exhaled Breath of Glucose Fluctuation in Type 1 Diabetes
Volatile Organic CompoundsHypoglycemia1 moreThe investigators are investigating the "biochemical fingerprint" of hypoglycemia (low blood sugar) in the breath of people with type 1 diabetes.
Glycemic Control and Treatment Satisfaction in Children With Type 1 Diabetes Using Insulin Pumps...
T1DMBackground: The use of insulin pumps in pediatric patients with type 1 diabetes(T1D) has expanded, with lack of data comparing between the different devices. Objective: to compare prospectively glycemic control, technical difficulties and quality of life (QOL) between 3 pump devices during the first year of use . Methods: a prospective observational trial, based on clinical data retrieved during 12 months of follow- up. Inclusion criteria included T1D patients, ages 1-18 years, who started pump therapy as part of their clinical care in 4 university affiliated medical centers. The devices fully reimbursed by national health insurance are: MiniMed™ 640G , MiniMed® Veo™, Animas® Vibe®, and Abbott Omnipod®. Comparison parameters included quality of life (QOL), frequency of technical difficulties, skin reactions, discontinuation rate, glycated hemoglobin (HBA1C), mean glucose, total daily insulin dose (TDD) , pump setting parameters and BMI.
A Canadian Study of the Effectiveness of Tresiba® (Insulin Degludec) After Switching Basal Insulin...
Diabetes MellitusType 12 moreThe purpose of this study is to collect historical data in real life conditions in a large group of people who have type 1 or type 2 diabetes and were treated with Tresiba® (insulin degludec) for at least 6 months. Data will be collected beginning 6 months before the participant started Tresiba® up to around 6 months after the participant started taking insulin degludec.
Bone Health and Microbiome in Persons With Type 1 Diabetes
Type1diabetesIt is well-established that persons with type 1 diabetes (T1D) are at an increased risk for morbidity and mortality related to bone fracture due to poor bone health, however we do not fully understand the mechanism behind the increased fracture risk. We are examining bone health and the microbiome in adolescents and young adults with type 1 diabetes to better understand the reasons behind this increased risk.
Avoidance of Hyperglycaemia in People With Type 1 Diabetes
Diabetes MellitusType 1This study aims to learn more about avoidance of hyperglycaemia in adults with type 1 diabetes. People who attend a type 1 diabetes clinic will be invited to complete a number of self-report questionnaires and a survey. A subsection of people who experience avoidance of hyperglycaemia will be invited to take part in an interview in order to gain a more in-depth understanding of this issue.
Food Collection From Type 1 Diabetic Patients Practicing Insulin Functional Therapy
Diabetes Type 1a food collection will be performed in this study with type 1 diabetic patients trained to carbohydrate counting, to collect data on the meals consumed daily and their quantities for a period of 1 month.
