Randomization will be performed by someone other than the researcher. The experimental group will receive gamified education in addition to standard education, while the control group will receive only standard education. Data will be analyzed using the SPSS program. The research will be conducted in accordance with the principles of the Helsinki Declaration. Findings: The findings of the study will be analyzed using SPSS after the application and data collection are completed. Conclusion: The results of the study will be written after the application of the study and the collection of data, followed by the analysis of the data using SPSS and the determination of the findings.

The goal of this clinical trial is to ensure that contact dermatitis is not prohibiting any person with diabetes the access to the optimal treatment. The main questions this study aims to answer are: 1. How many pediatric patients with contact dermatitis due to diabetes devices experience recurrence of contact dermatitis depending on which type of patch they use under their device. 2. Is one type of patch (silicone-based vs. hydrocolloid patch) better than the other at preventing contact dermatitis? The group being investigated is children and adolescents aged 2-18 years with contact dermatitis caused by either an insulin pump or a continuous glucose monitor. The participants will be asked to do different surveys on well-being and they will go to three physical visits. At the visits the the following will happen: * clinical skin examination * skin picture (of last used pump and sensor site as well as reportet skin reactions) * height and weight * blodsample (HbA1c and fillagrin mutations) * interview on skin reactions etc. * ultrasound of the skin * tape strips of the skin * EIS (transmit harmless electrical signal through the skin)

The objective of the study is to evaluate whether pre-exercise administration of low-dose subcutaneous glucagon prevents or attenuates exercise-induced declines in plasma glucose concentration during and after moderate-intensity continuous exercise (MICE) performed approximately 90 minutes after a meal in adults with type 1 diabetes using an automated insulin delivery (AID) system. The primary endpoint is the difference in the change in plasma glucose (PG) from exercise initiation to the nadir during exercise and through the 2-hour post-exercise period between the glucagon (GCN) and carbohydrate (CHO) visits.

INHALE-1st is a Phase 2, single-arm, multi-center, clinical study evaluating the safety and efficacy of Afrezza in combination with subcutaneously-injected basal insulin (BI) for youth 6 to \<18 years old with newly diagnosed stage 3 type 1 diabetes (T1D). The study will also evaluate the effect of an Afrezza plus BI reigmen on participant and parent/legally authorized representative satisfaction. Participants will be followed for 13 weeks during the main phase followed by an optional Extension Phase for participants continuing to use Afrezza in combination with BI for up to 26 weeks.

The purpose of this study is to check that a new insulin pump, called NMX8, is safe when used with a continuous glucose monitoring sensor called Disposable Sensor 5/Simplera Sync in people with diabetes. The study will include people with Type 1 diabetes who are 7-85 years old and people with Type 2 diabetes who are 18-85 years old. Participants will use their current therapy while also wearing the DS5/Simplera sensor for up to 40 days. During this time, they will complete a meal and exercise log. Participants will then be placed into one of three groups by chance and given the NMX8 pump to use for about 90 days. During this time, participants will bolus, not bolus, or bolus at will for meals and continue to complete a meal and exercise log depending on the group they are in. Once their part in the study is over, if participants like the pump and want to keep using it, they may be able to join a Continued Access Period to keep using the NMX8 pump.

This study evaluates a clinician-facing decision-support toolkit designed to assist adults with type 1 diabetes in preparing for moderate-intensity exercise. The netIOB \& Exercise Toolkit (NEXT) integrates recent glucose data and insulin delivery history to provide individualized suggestions regarding exercise timing, insulin adjustments, and carbohydrate intake. Adults with type 1 diabetes will complete three supervised exercise sessions under different pre-exercise guidance approaches: (A) published consensus-based standard-of-care guidance, (B) usual personal care routines, and (C) guidance informed by the NEXT Toolkit. A healthy adult control group will complete a single supervised exercise session to provide comparative physiologic data.

This is a 78-week single arm, multi-center, Phase 1 study to evaluate the safety, tolerability, cellular kinetics, and biomarker changes in C-peptide over time of GNTI-122, an investigational cell therapy manufactured from a participant's own blood cells in adult participants with recently diagnosed T1D. After assessment of eligibility, participants who qualify for the study will be enrolled sequentially in 1 of 3 cohorts. Cohort 1 participants (n=3) receive a low dose of GNTI-122 . Cohort 2 participants (n=3) receive a high dose of GNTI-122. Cohort 3 participants (n=10) receive a high dose of GNTI-122 in combination with rapamycin. Participants are followed for 78 weeks after the administration of GNTI-122 during which safety and efficacy assessments are made, including vital signs, ECG, physical exam, clinical labs, and monitoring of adverse events and concomitant medications. Disease markers (e.g., MMTT-stimulated C-peptide, HbA1c) and pharmacodynamic activity (e.g., lymphocyte subsets and phenotypes, effector T cell responses to islet antigens ex vivo, T1D autoantibodies) will be monitored serially throughout the study. The study will include sentinel dosing and a Safety Review Committee to ensure participant safety. Visit https://www.polarisstudy.com to learn more!

This is a multicenter, randomized, double-blind, parallel, placebo-controlled Phase 3, 2-arm study for treatment. The purpose of this study is to measure change in glycemic control and prandial insulin independency over 52 weeks with teplizumab compared with placebo, both administered by intravenous (IV) infusion, in participants with recently diagnosed Stage 3 type 1 diabetes (T1D) aged 1 to 25 years, on standard insulin therapy.

This study will examine the effects of Tirzepatide (TZP), a glucagon-like peptide 1 (GLP1) - gastric inhibitory peptide (GIP) co-agonist, on metabolism in type 1 diabetes (T1D). Research participants with T1D will undergo measures of insulin sensitivity, and hormone levels post-meal, post-hypoglycemia and during the overnight period. These measures will be performed prior to, and after 6 weeks of treatment with TZP or placebo.

This study aims to evaluate whether using ultrasound (phonophoresis) can help deliver propolis-a natural compound made by bees-more effectively into the skin to speed up wound healing in people with diabetic foot ulcers. Diabetic foot ulcers are a common and serious complication of diabetes and often take a long time to heal. Propolis has natural anti-inflammatory and antimicrobial properties that may promote healing, but it does not easily penetrate the skin. By using ultrasound to enhance absorption, this study tests whether combining propolis with phonophoresis is more effective than standard wound care alone. Participants will be randomly assigned to receive either the propolis ultrasound therapy or standard care. The study will measure wound size, healing time, pain, infection rates, and quality of life.

This multi-center, randomized, cross-over trial will evaluate the efficacy of the Omnipod 6 System compared with the Omnipod 5 System in individuals with type 1 or type 2 diabetes and suboptimal glycemia.

This is a non-randomized, parallel-controlled, single-center, open-label clinical trial designed to evaluate the efficacy of dimethyl fumarate in preserving pancreatic beta-cell function in adults with type 1 diabetes, as well as its safety and tolerability in this population. Eligible participants are adults aged 18 to 65 years who meet the ADA 2024 diagnostic criteria for type 1 diabetes, have at least 2 positive islet autoantibodies, and have residual beta-cell function as evidenced by a random C-peptide level of at least 200 pmol/L. A total of 96 participants are planned for enrollment, including 32 in the dimethyl fumarate treatment group and 64 in the standard-treatment control group. Participants in the treatment group will receive dimethyl fumarate enteric-coated capsules in addition to standard insulin therapy for type 1 diabetes. Dimethyl fumarate will be initiated at 120 mg twice daily and increased after 7 days to a maintenance dose of 240 mg twice daily. Participants in the control group will receive standard insulin therapy alone. The intervention period will be 24 weeks, followed by 52 weeks of follow-up. The primary efficacy endpoint is the baseline-adjusted geometric mean area under the serum C-peptide curve during a 2-hour mixed-meal tolerance test at Week 24. Secondary endpoints include measures of beta-cell function at multiple time points, changes in glycated hemoglobin, proportions of participants with good or poor glycemic control, insulin dose requirements, and immunologic markers including lymphocyte subsets, cytokine profiles, and islet autoantibody characteristics. Safety assessments will include the incidence of flushing, gastrointestinal adverse events, allergic reactions, opportunistic infections, liver function abnormalities, lymphopenia, renal abnormalities, hypoglycemia, severe hypoglycemia, ketosis, and ketoacidosis. The total study duration is 36 months, from January 2026 to December 2028.

The proposed project is a clinical intervention trial testing the feasibility and effectiveness of diabetic retinopathy screening evaluated by artificial intelligence (AI) based software in children with type 1 diabetes (CwD). Another novel method, the confocal microscopy of the retina will be used to assess the early stages of diabetic neuropathy. In parallel, we aim to assess the prevalence of diabetic retinopathy and neuropathy in a well-controlled population of CwD at a tertiary diabetes care center. Each participant will undergo an examination of diabetic retinopathy using the non-mydriatic fundus camera. The resulting photography will be evaluated by AI driven software. The participant will then follow this examinaton with fundus ophtalmoscopy in arteficial mydriasis as a standard method of diabetic retinopathy assessment. Another method, the optic coherence tomography (OCT), which is considered as the most sensitive method for diabetic retinopathy assessment, will be performed after that. The results of these methods will be compared to assess the sensitivity of each. The examination-satisfaction questionnaire will be given to the participants. In subjects over 18 years, a confocal microscopy of the retina examination will be performed to assess the status of the corneal sub-basal nerve plexus and the presence of diabetic neuropathy will be noted. The prevalence of diabetic retinopathy and neuropathy in this group of children with diabetes will be assessed based on the results.

This study aims to evaluate the effectiveness of a mobile health (mHealth) educational intervention for adolescents with Type 1 Diabetes Mellitus (T1DM). Adolescents often face challenges in maintaining optimal blood glucose control and performing regular self-care. In this study, participants will receive structured diabetes education through a mobile application designed to improve their knowledge, self-efficacy (SE), and self-management skills. The impact of the intervention will be assessed by measuring changes in HbA1c levels, diabetes self-efficacy, and self-care (SC)behaviors over time. These findings may help determine whether mobile app-based education can support better diabetes management among adolescents.

The goal of this clinical trial is to evaluate the safety and performance of the SAVA Continuous Glucose Monitor across glucose ranges over a period of 15-day wear in adults over 18 years of age with Type 1 Diabetes. This is a pilot study, so the main purposes are to collect preliminary data for future studies, assess comfort and safety, and explore the accuracy of the CGM against references and benchmarks.

Diabetes mellitus is a group of chronic metabolic diseases characterized by hyperglycemia .Type 1 diabetes is a heterogeneous disease related to the destruction of pancreatic beta cells and is a result of absolute lack of insulin * Diabetes mellitus has been traditionally looked upon as a disease of adults (except Type I diabetes), however it can affect individuals of any age. Given the peculiarities and problems that it carries, diabetes in children and adolescents poses special challenges to the entire society. Diabetes is the second commonest chronic disease occurring in 1 in every 1500 children by age 5 and in 1 in 350 children by age 8 . Microvascular (retinopathy, neuropathy, and nephropathy) Aim of the research to assess basic hematological parameters and coagulation profiles among type 1 diabetic children and compare them with healthy controls and macrovascular (coronary artery disease, peripheral vascular disease, and cerebrovascular disease) atherothrombotic complications may occur in children and adolescents, depending on the duration of diabetes, the degree of metabolic control, and other factorssuch as genetics . Diabetes mellitus can cause blood disorders such as deformity of red blood cells and increase their adhesion \[6\].It has an effect on the function of red blood cells through the interaction with the membrane and intracellular components . Red blood cell distribution width (RDW) is a measure of the difference in the size of red blood cells. An increase in RDW can be caused by anemia or nutritional deficiencies related to anemia * Studies have shown that the average number of red blood cells, hemoglobin and hematocrit in diabetic patients is lower than the control group, which indicates the presence of anemia in diabetic patients .

This is a parallel, Phase 2, two-arm study to assess the efficacy and safety of 14-days intravenous (IV) infusion of teplizumab treatment. Teplizumab has been approved by FDA to delay the onset of Stage 3 Type 1 Diabetes (T1D) in adults and pediatric patients aged 8 years and older with Stage 2 T1D. The dose regimen of teplizumab in this study is consistent with the regimen approved by US FDA. Given prior clinical studies conducted in Western countries, this design is appropriate to assess the efficacy, safety and tolerability, pharmacokinetic, pharmacodynamic, and immunogenicity of a 14-day IV infusion regimen of teplizumab in Japanese Stage 2 T1D participants aged 1 to 34 years.

The goal of this clinical trial is to learn whether an AI-powered carbohydrate counting educational platform can help parents of children with type 1 diabetes improve their carbohydrate counting skills and diabetes management. The study will include parents or primary caregivers of children aged 2-12 years with type 1 diabetes. The main questions it aims to answer are: * Is the AI-powered educational platform feasible, acceptable, and easy for parents to use? * Can the platform improve carbohydrate counting accuracy, parental confidence in diabetes management, and diabetes outcomes compared with usual education alone? Researchers will compare parents who receive access to the AI-powered carbohydrate counting educational platform plus usual diabetes education with parents who receive usual diabetes education alone to see whether the AI-supported approach provides additional benefits. Participants will: * Complete baseline assessments, including questionnaires and a carbohydrate counting test. * Be randomly assigned to either the AI-supported education group or the usual education group. * Use the assigned educational resources for 12 weeks. * Complete a follow-up assessment at 6 weeks and a final assessment at 12 weeks. * Provide information about their child's diabetes management, including HbA1c and glucose monitoring data. * Complete questionnaires about confidence, usability, and satisfaction with the educational support they receive. The AI platform is designed to provide educational support only and does not replace medical advice, insulin dosing decisions, or routine diabetes care provided by healthcare professionals.

This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: * follow participants to determine how long they continue to produce insulin, and * will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future.
