Integrating New Skills Into Diabetes Education With CGM
This study is designed to test the preliminary efficacy of a three-stage continuous glucose monitor (CGM) integration program for older adults who are taking insulin. This study will learn if a three-stage CGM integration program ("intervention") that includes sessions focused on CGM technology skills, data skills, and lifestyle skills impacts CGM wear-time, glycemic metrics, and participant-reported outcomes, compared to two standard CGM training approaches ("comparators"). Following a screening visit and baseline data collection, participants will be randomized to either the intervention or one of the two comparator arms for 6 weeks. The intervention involves three educational sessions over 4 weeks. The first session will be in-person and subsequent sessions will be virtual. Participants in the intervention may receive 1-2 additional individualized training sessions to review CGM skills. The first comparator (Comparator A) will receive a one-time clinic-based CGM training. The second comparator (Comparator B) will be provided with a comprehensive informational pamphlet about CGM. All participants will complete outcomes data collection at 6 weeks. The study will also explore participant experiences through a series of semi-structured interviews with a subset of purposively selected participants and their care partners to identify opportunities for scaling the intervention to a broader population. An extension phase of the study will evaluate long-term CGM use and associated outcomes 3- and 6-months post-intervention. Lastly, we will run an additional small sub-study where consented care partners of participants will attend the intervention or comparator sessions alongside the study participant and provide care partner-specific data.

Type 1 Diabetes Screening
This study examines how population-based screening for type 1 diabetes (T1D) using islet autoantibodies (i.e., immune system proteins) can be incorporated into pediatric primary care during routine well-child visits. The project evaluates whether this screening approach is feasible, acceptable, and appropriate for clinicians, parents, and other key constituent groups. The study also explores how often clinicians order the test and how often families complete it when integrated into existing workflows. Insights from parents, clinicians, and organizational leaders will inform future scale-up efforts and practical strategies to improve early detection of T1D in pediatric practices across the United States.

Effect of Melatonin Supplementation on Excecutive Functions, Sleep Quality and Glycemic Metrics Among Adolescents With Type 1 Diabetes Mellitus
Cognitive impairment, poor sleep quality, Alzheimer's disease and dementia are complications of uncontrolled type 1 diabetes (T1D). Melatonin; a hormone secreted from the pineal gland; previously associated with sleep and cognition; has recently been associated with insulin secretion and glucose homeostasis. People with diabetes have low serum melatonin levels. Moreover, melatonin adminstration was found to decrease anxiety, depression signs, and glycated hemoglobin (HbA1c) in diabetic rats . Hence, this study assessed the effect of melatonin adminstration add on therapy on excecutive functions, sleep quality and glycemic metrics among adolescents with T1D.

Pilot of Food Is Medicine Interventions to Reduce Cardiovascular Disease Risk in Children With Food Insecurity and Diabetes
Study Design: This two-arm parallel trial will randomize 12 families to receive 6-weeks of medically tailored meals or produce prescriptions. Both groups will receive nutrition coaching, weekly during the intervention. The hypothesis is that both interventions to have a positive impact on food security and fruit and vegetable intake. However, medically tailored meals also reduce the logistic barriers of planning, preparing, and calculating the carbohydrate content of nutritionally balanced meals essential for DM management. Therefore, the medically tailored meal intervention will result in greater improvements in the co-primary outcomes of diet quality and glucose stability after the intervention.

A Study of GNTI-122 in Adults Recently Diagnosed With T1D
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!

Kidney Precision Medicine Project
Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: * Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD * Define disease subgroups * Create a kidney tissue atlas * Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: * Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. * Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. * Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.

Capillary OGTT Study
Type 1 diabetes (T1D) is a chronic condition, affecting 1 in 490 children under the age of 15 years. It is caused by the immune system damaging the pancreas, the organ which makes insulin. T1D has recognised stages before symptoms develop, providing an opportunity for early diagnosis, education and treatment which may delay the onset of symptoms. Type 2 diabetes (T2D) is also a chronic condition where the body cannot make enough insulin, or cannot respond to the insulin properly. It is usually related to obesity, rather than an immune problem. It is more common in adults, but the early stages often start in childhood (up to 1 in 4 children in some clinics). Like T1D, early detection can delay onset of T2D, or even prevent it altogether. Early diagnosis of T1D or T2D often relies on a test called the oral glucose tolerance test (OGTT), which is commonly used but not well tolerated, possibly because it requires a drip inserted into the vein, and several blood samples taken over 2-3 hours in a healthcare setting. Our study aims to test whether we can do an OGTT using a finger-prick to test glucose, at home. We call this the 'GTT@home'. The finger-prick creates a drop of blood, which is done before and two hours after drinking a sugary drink. We will also explore whether a continuous glucose monitor (CGM), which reads glucose levels through the skin could be an alternative. We plan to recruit 90 children and young people, across two groups to assess the GTT@home. To understand the experiences of those involved in monitoring, we will invite young people, parents and healthcare workers to take part in an interview, to understand the impact of testing to predict clinical T1D. Group 1 will assess the accuracy of measuring glucose from a finger-prick blood test when compared to a blood test from the vein. We will recruit individuals who are having an OGTT as part of a research study, for clinical care or if they have agreed to have an OGTT for this study. Those with T1D will be invited to wear a CGM to explore its use as an additional, practical alternative. Groups 2 and 3 will assess how well the GTT@home test works when done at home and how acceptable it is. This will only be offered to those known to be at risk of T1D. These studies will help us to understand if the GTT@home can be used in routine care.

Standardized Italian netwoRk Enrolling iNdividuals With Islet-Autoantibodies
This project characterizes the longitudinal progression of children and adults who have tested positive for one or more islet cell autoantibodies across the early stages of type 1 diabetes (T1D). Despite advances in screening, limited evidence exists on how clinical, metabolic, and immunological markers evolve over time and predict progression to symptomatic disease. Using a screened cohort, participants are followed for up to 10 years with repeated standardized assessments. The study evaluates whether population-based screening can reduce diabetic ketoacidosis (DKA) at diagnosis and identify early predictors of progression to clinical T1D. Results are expected to improve risk stratification, inform surveillance strategies, and guide the timing of preventive interventions, with implications for clinical practice and health policy.

Study of Glucose Tolerance Abnormalities Using Continuous Glucose Monitoring for the Identification of Early Loss of Pancreatic Islet Graft Function.
Islet transplantation is associated with drastically improvement glucose control in people with type 1 diabetes. This treatment resulted in the disappearance of severe hypoglycemic events. However, its long-term effectiveness is limited by progressive loss of graft function. Currently, there is no standardized method to detect early dysfunction of the transplanted islets. This study aims to determine whether a parameter derived from continuous glucose monitoring (CGM), Time in Tight Range (70-140 mg/dL), is associated with pancreatic islet grafts function. The study hypothesis is that a decrease in Time in Tight Range reflects early loss of islet graft function.

Feasibility and Adoption of a Screening Program for T1D Relatives in Canada
The aim of this study will be to evaluate the feasibility of an autoantibody-based type 1 diabetes screening program for first degree relatives of people living with type 1 diabetes within the province of Quebec. Feasibility of follow-up strategies of "at-risk" individuals will also be assessed. This project will be divided into two phases, with the aim to evaluate: 1. The feasibility of a IAb (islet antibody)-based screening process for first degree relatives of people living with type 1 diabetes (T1D). 2. The feasibility of two approaches for follow-up monitoring in case of positive screening: centralized (within the organization) and decentralized approach (relying on individuals' healthcare providers), in the Quebec province setting. Participants will come to the laboratory for blood sample collection, medical history and genetic risk score assessment, as well as anthropometric and cutaneous advanced glycated end (AGE) products measurements. A series of questionnaires will be completed. After screening results are obtained (i.e., presence or absence of IAbs), a virtual visit will be conducted to communicate results to participants. A positive result for IAb will warrant a second test for confirmation , using WBD within 3 months of initial screening. After IAb positivity confirmation, participants will be invited to participate in phase 2 of this project (monitoring). Participants will be given the opportunity to select either a centralized or decentralized path for study monitoring. Follow-up will be dependent of the stage of T1D: * Participants in pre-stage 1 or stage 1 (2 or more positive IAbs without dysglycemia) T1D will receive a follow-up phone call six months after the initial screening. * Participants in stage 2 (2 or more positive IAbs with dysglycemia) will be contacted one month after screening.
