Type 1 Diabetes Mellitus

The goal of this clinical trial is to learn whether DiaBuddy, a digital self-management app, can help children and adolescents with Type 1 diabetes better manage their condition and reduce the burden experienced by their caregivers. The study will include children and adolescents aged 6 to 17 years with Type 1 diabetes who live in Pakistan. The main questions it aims to answer are: * Does using DiaBuddy along with usual diabetes care improve diabetes self-management and adherence? * Does using DiaBuddy along with usual diabetes care reduce caregiver burden? * Does using DiaBuddy affect blood sugar control, diabetes-related distress, and other diabetes-related health outcomes? * Is DiaBuddy acceptable and useful for children, adolescents, and their caregivers? Researchers will compare participants who use DiaBuddy along with their usual diabetes care with participants who receive usual diabetes care alone. Participants will: * Use DiaBuddy to record and review information related to their diabetes, including blood glucose and self-management activities. * Receive diabetes education, reminders, and self-management support through the app. * Complete questionnaires about diabetes self-management, diabetes-related experiences, and caregiver burden. * Have blood sugar control assessed through laboratory-verified HbA1c measurements. * Attend scheduled follow-up assessments at approximately 3 and 6 months. * Report relevant diabetes-related health events, such as hypoglycemia, diabetic ketoacidosis, emergency visits, and hospitalization.

Participants will be administered rezpegaldesleukin/placebo once every 14 days over 26 weeks with an additional 6-month follow-up period.

Type 1 diabetes (T1D) in children involves autoimmune destruction of pancreatic ß- cells, leading to insulin deficiency. Verapamil is an L-type calcium channel blocker that has been used for decades to treat hypertension and certain cardiac conditions. Recent research has revealed its potential as a ß- cell-protective agent. Hence this study will evaluate the effect of once-daily oral verapamil on pancreatic ß- cell reserve , glycemic metrics and daily insulin requirements in children and adolescents with T1D.

BACKGROUND Functional ovarian hyperandrogenism, including the polycystic ovary syndrome (PCOS), is very prevalent in women with type 1 diabetes (T1D). The pathogenic mechanisms of this association remain unclear. HYPOTHESIS Individual factors expose or protect women with T1D to/from the development of androgen excess and PCOS. Such androgen excess in women with T1D may increase their cardiometabolic risk. MAIN OBJECTIVE Unveiling the pathogenic mechanisms behind functional hyperandrogenism in women with T1D from a sex/gender-medicine and sexual dimorphism perspective. MATERIAL AND METHOS We have designed a cross-sectional comparative clinical study, including 5 groups of study subjects with 12 participans per group: i) Women with T1D \& PCOS. ii) Women with T1D without PCOS. iii) Men with T1D and normal gonadal function. iv) Women with PCOS without diabetes mellitus v) Non-hyperandrogenic control women without T1D. All groups will show similar age and body mass index. T1D groups will be matched for duration of disease. OUTCOMES 1.1 Insulin sensitivity (hyperinsulinaemic euglycaemic clamping). 1.2 Body composition (dual-energy x-ray absorptiometry, bioelectrical impedance analysis \& sonographic studies). 1.3 Ovarian and adrenal steroidogenesis. 2.1 Differential pattern in genetic variants related with insulin signalling and response, inflammation, adiposity, gonadal function, steroidogenesis, and PCOS itself by whole exome sequencing. 2.2 Microbiopsy studies in deep subcutaneous adipose tissue and skeletal muscle tissue: 2.2.1 Differential DNA methylation patterns in genes associated with PCOS. 2.2.2 Differential transcriptomic pattern in genes associated with PCOS. 2.2.3 Differential proteomic patterns in adipose and muscle tissues. 3. Interaction between T1D and PCOS on parameters of metabolic control (intersticial blood glucose monitoring) and morbidities associated with T1D itself.

The goal of this clinical trial is to develop and evaluate a novel diabetes ketoacidosis risk mitigation strategy to support the safe use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) therapy in participants with type 1 diabetes (T1D) and mild to moderate chronic kidney disease (CKD). The main objectives of this study are to: 1. Evaluate how ketone metrics differ between participants no chronic kidney disease (CKD), moderate risk CKD and high or very high-risk CKD in three time periods. 2. Identify potentially modifiable ketosis risk factors. 3. Use continuous dual ketone and glucose monitoring (DGK) data prior to and following treatment to determine ketosis risk factors and gain knowledge to further refine reporting of risk factors and determine which factors in the Ketone Action Plan (KAP) were most valuable. 4. Gather information on how participants and clinicians like and use the DGK reports. Participants will be asked to: * Meet with study investigators to determine if they are eligible * Sign written informed consent * Take a pregnancy test, if applicable * Have blood taken to assess kidney function and hemoglobin A1c * Take the study medication, following the study team instructions * Wear the study provided sensor throughout participation. * Complete 5 in person visits, and 11 phone check ins over a nine-month period * Provide feedback on their experience, usefulness of CGM/CKM reports, and the most valuable factors of the Ketone Action Plan (KAP).

The goal of this clinical trial is to ensure that contact dermatitis does not prevent any person with diabetes from accessing optimal diabetes treatment. The main questions this study aims to answer are: How many pediatric patients with diabetes device-related contact dermatitis experience recurrence of contact dermatitis depending on the type of patch used underneath their device? Is one type of patch (silicone-based or hydrocolloid) more effective than the other at preventing contact dermatitis? The study population consists of children and adolescents aged 2-18 years with contact dermatitis (CD) caused by either an insulin pump or a continuous glucose monitor (CGM). Participants will be asked to complete questionnaires about their well-being and attend three in-person study visits. During these visits, the following assessments will be performed: Clinical skin examination Skin photographs of the most recently used insulin pump site, CGM site, and any reported skin reactions Measurement of height and weight Blood sample for measurement of long-term blood glucose (HbA1c) and filaggrin gene mutations Interview about skin reactions and related symptoms Skin ultrasound Tape stripping of the skin Electrical impedance spectroscopy (EIS), a non-invasive technique that transmits a harmless electrical signal through the skin

This study will evaluate the introduction and use of the Omnipod® 5 hybrid closed-loop insulin delivery system in children and adolescents with type 1 diabetes following its reimbursement in Belgium. The study will describe how quickly the system is adopted in routine paediatric diabetes care, which patients are offered this technology, and the reasons for choosing Omnipod® 5. It will also evaluate changes in the use of different insulin pump systems and assess diabetes control, safety, and continued use of Omnipod® 5 during follow-up. The study is observational, meaning that participants will receive their usual diabetes care and their treatment will not be changed for research purposes. Information collected during routine diabetes follow-up, including glucose sensor, insulin pump, and medical record data, will be analysed. No additional examinations, blood tests, or hospital visits will be required for participation.

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 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.
