Active clinical trials for "Diabetes Mellitus, Type 1"

The study seeks to evaluate a novel treatment approach for performing continuous real-time glucose sensing and insulin delivery at the same subcutaneous tissue site.

The purpose of this exploratory study is to evaluate the characteristics of sleep, perceptions of barriers and facilitators to adequate sleep, and the associations among sleep characteristics, executive functioning, coping, adherence, 24-hour glucose levels, and adjustment in adolescents with type 1 diabetes. A mixed methods approach that includes a quantitative component, consisting of actigraphy and sleep diaries, questionnaires, tests of executive function and continuous glucose monitoring (CGM) as well as a narrative qualitative component will be used. Results from this pilot study will be used to provide the effect sizes needed for a larger-scale descriptive study and to establish the need for a possible sleep-promoting intervention for adolescents with type 1 diabetes. This project is consistent with ongoing research focused on developing preventive, behavioral interventions for youth with type 1 diabetes and their families to improve physiological (i.e., glycemic control) and psychological (i.e., quality of life) outcomes. Sleep promotion may become an important component of these interventions. Thus, the following specific aims will be addressed: Describe the objective and subjective characteristics of sleep (duration, continuity, bed time/rise times); sleep quality and sleep habits among adolescents with type 1 diabetes. Explore the relationship between characteristics of self-reported sleep (i.e., habits, duration, daytime sleepiness) and executive function, coping, adherence, and adjustment (i.e., depressive symptoms, quality of life) in adolescents with type 1 diabetes. Explore the relationship of glucose excursions on sleep characteristics and executive functioning. 3. Conduct a qualitative study using narrative analysis with adolescents to identify perceived barriers, facilitators, and consequences associated with insufficient sleep in adolescents with type 1 diabetes.

This study aimed to evaluate the levels of interleukin 18 and tumor necrosis factor-alpha (TNF-α) in gingival crevicular fluid (GCF) of children with type 1 diabetes mellitus and gingivitis.

With an increased incidence of pediatric type 1 diabetes (T1D) and a decrease in age at diagnosis, children are exposed to complications such as renal impairment at a very young age. The current biomarker used to diagnose renal impairment is microalbuminuria, but it's a late marker. Early screening is a major issue to reduce T1D consequences. Early glomerular hyperfiltration (GHF) could participate in the development and progression of nephropathy. Hyperfiltration has also been associated with a systemic endothelial dysfunction and with changes in arterial stiffness, suggesting, at least to a certain extent, a state of generalized vascular dysfunction. Diabetes is responsible for very early neurovascular dysfunctions, detectable with techniques to evaluate cutaneous neurovascular interaction. Those should help bringing to light very early microcirculation impairment, particularly precocious endothelial dysfunction (ED). No study about correlation between GHF and ED is currently available. The hypothesis assessed is those of a strong correlation between ED and GHF in children and adolescent with a story of T1D for at least 10 years. This pilot study should allow assessing ED's and GHF's proportions in our population, in order to conduct a larger study to prove, in a prospective way, the prognostic value of ED in the apparition of nephropathy, taking into count other factors such as diabetes duration or stability. This measure could be included in the global evaluation of microangiopathy risk in children and then take action to prevent negative outcomes. The second aspect of this study is the assessment of other functions and metabolisms possibly impaired in T1D: osseous microarchitecture, vitamin D status and precocious evaluation of macro angiopathy through intima media thickness measurement. Long term diabetes in children is associated with shorter and leaner bones, despite a correct mineralization, a reduced bone density and a fracture risk increased six fold. Bone status in the population will be evaluated through the study of bones microarchitecture via HR-pQCT (High Resolution peripheral Quantitative Computed Tomography) on both tibia and radius, dual-energy X-ray absorptiometry (DXA), and bone turn over biochemical markers. Results on bone microarchitecture in a preexisting cohort of healthy children and adolescents will be used to compare results.

The current study aims to assess clinical outcomes in adults with type 1 diabetes (T1D) who have switched from traditional multiple daily injection (MDI) therapy to continuous subcutaneous insulin infusion (CSII) therapy with the Omnipod insulin system.

This project will assess self-efficacy levels(SE) ,resiliency and attachment style of adolescent with type 1 diabetes and their caregivers.SE and attachment style of patients and parents will be compared with each other as well as correlated with diabetes management as assessed by A1C and self inventory scale.

The purpose of this study is to compare a needle-free treatment of hypoglycemia with nasal glucagon (study drug) to a marketed glucagon administered by the intramuscular (IM) route, in participants with type 1 diabetes mellitus (T1DM).

Patient participation in decision making about their care promotes patient satisfaction and confidence. Further more, allowing patients to see letters written about them enables trust, encourages patients to be involved in decision making process and allow patient understanding. Little is known about how young people value these letters in the same way. Only one brief questionnaire study focused on adolescent views and found that young people wished to receive consultation summaries. This research aims explore the views of adolescent patients related to consultation summaries that they receive following a doctor's appointment. The investigator will use patients attending a specialist diabetes clinic as our cohort and conduct a qualitative study using focus groups.

The investigators aim to further the understanding of environmental factors that may underlie variations in body composition seen in youth with Type 1 diabetes (T1D). Non-caloric artificial sweeteners, broadly consumed in many individuals with T1D, are a modifiable dietary factor that may be associated with negative health outcomes, particularly those relevant to the future risk of diabetes-related complications. Investigators will measure body composition (the amount of fat and muscle in the body and where the fat is stored) using a bioelectrical impedance analysis machine and DEXA scanner. Blood will be drawn for the following labs: HbA1c, lipid panel, comprehensive metabolic panel and leptin. Participants will also answer questions about their diets and consumption of artificial sweeteners.

Fiasp® is a meal-time insulin that has been available in Sweden since June 2017. This study will investigate the effectiveness of Fiasp® in treating Type 1 Diabetes Mellitus. The study will be based on blood sugar measurements that the participants have uploaded to the Diasend® database and on existing data in their electronic medical records. The study does not require any additional visits to the study doctor.
