GATEWAY: Safety Evaluation of the MiniMed™ NMX8-AID System in Children and Adults Living With Diabetes

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.

Subcutaneous Pharmacokinetic Evaluation of Monomeric Insulin and Lyumjev in Adults With Type 1 Diabetes

The SPEED study is a randomized, crossover pilot study evaluating the pharmacokinetics of novel insulin formulations in adults with type 1 diabetes. The study compares two experimental insulin formulations (diluted U-200 Humalog and U-500 Humulin with sterile water, mannitol and EDTA) against commercially available U-100 Lyumjev to determine if these modifications can improve insulin onset and duration of action. Twenty participants will complete three study visits, each separated by at least48 hours. At each visit, participants will receive one of the three insulin formulations (0.20 u/kg) via subcutaneous injection following consumption of a standardized mixed meal. Blood samples will be collected frequently over 6 hours to measure insulin concentrations and assess pharmacokinetic parameters, including time to maximum concentration (Tmax), maximum concentration (Cmax), elimination half-life, and area under the curve. The study aims to address limitations of current insulin formulations used in automated insulin delivery systems, which are too slow to provide optimal meal coverage without pre-meal dosing. By reducing zinc content through EDTA chelation and decreasing metacresol concentration through dilution, these novel formulations may offer faster onset and shorter duration of action, potentially improving glucose control in people with type 1 diabetes using insulin pump therapy.

Basic Hematological Parameters and Coagulation Profile in Type 1 Diabetic Children

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 .

Effect of Dietary Carbohydrate Content and Inulin-Fructooligosaccharide Supplementation on Glycemic Control in Individuals With Type 1 Diabetes Mellitus

Diabetes is a chronic metabolic disease in which nutrients such as carbohydrates, fats and proteins cannot be utilized sufficiently due to the inability to produce insulin or defects in the effect of the produced insulin. The risk of individuals encountering complications related to diabetes decreases when glycemic control is achieved in these patients. Therefore, nutrition is an necessary component of treatment. Although there are many studies in the literature examining the effect of carbohydrate intake on glycemic control in individuals with diabetes and monitoring carbohydrate intake in individuals with diabetes is the basic strategy for reaching glucose targets, a common denominator has not yet been reached for the optimal amount of carbohydrate intake for individuals with diabetes. There are a wide range of definitions regarding carbohydrate intake and studies on carbohydrate restriction, especially in individuals with Type 1 diabetes, are limited. In present randomized controlled crossover study, three isocaloric different dietary treatment are planned to applied for 2 weeks in which (i) 30% of the daily energy requirement is provided from carbohydrates, not to fall below 130 g/day carbohydrates according to the individual characteristics of the patients, (ii) 50-55% of the daily energy requirement is provided from carbohydrates and (iii) carbohydrate content in the diet is adjusted without increasing the amount of carbohydrates, by supplementing 2 sachets (1 sachet 3.68 g inulin + 3.68 g ) where 50-55% of daily energy requirement is provided from carbohydrates together with fructooligosaccharide (FOS)) inulin fructooligosaccharide (FOS) supplementation. A 2-week washout period is planned between each diet model. The research will be conducted with 20 individuals with Type 1 diabetes using a Continuous Glucose Monitoring device. The proposed project aims to investigate the effect of different dietary treatments on glycemic control in individuals with Type 1 diabetes by using a continuous glucose measuring device. At the end of each dietary treatment application, the data obtained from the Continuous Glucose Measuring Device will be evaluated as the primary outcomes; total insulin dose, insulin/Carbohydrate ratio, total bolus insulin dose will be evaluated as the secondary outcomes. As a result of the research, the potential effects of different dietary treatments on glycemic control will be evaluated and the development of the most appropriate diet model for these patients will be contributed. In addition, this research will contribute to the improvement of the continuous glucose monitoring device.

Validation of Hemoglobin A1c in Patients With Inflammatory Arthritis Treated With Sulfasalazine

The purpose of this study is to examine whether the blood test Hemoglobin A1c (HbA1c) gives an accurate picture of blood glucose levels in patients with inflammatory arthritis who are treated with sulfasalazine. HbA1c is widely used to diagnose and monitor diabetes, but sulfasalazine can shorten red blood cell lifespan and thereby lower HbA1c values independently of actual glucose levels. This may lead to underdiagnosis of diabetes in patients who develop diabetes during sulfasalazine treatment, and to undertreatment in patients with known diabetes due to falsely reassuring HbA1c values. The study aims to answer two main questions: 1. How many patients treated with sulfasalazine have undiagnosed diabetes despite having HbA1c values below the diagnostic threshold? 2. Does HbA1c underestimate actual glucose levels when compared with continuous glucose monitoring (CGM) in patients with sulfasalazine-treated inflammatory arthritis, both in those with known diabetes and those that are not diagnosed with diabetes but have borderline HbA1c values (≥ 38 mmol/mol)?

Simultaneous Measurement and Responsive Treatment - Part 2

This research study is testing an investigational dual-port insulin patch pump that integrates a continuous glucose monitor (CGM) in adults with type 1 diabetes. The goal of the study is to better understand how insulin delivery near a CGM sensor affects glucose readings and to collect data to support development of a combined insulin pump and CGM system. People with type 1 diabetes require lifelong insulin therapy. Many use insulin pumps and CGMs, but these systems usually involve wearing multiple devices at different body sites. Managing several devices can increase treatment burden and may contribute to skin irritation, device failures, and challenges with glucose control. This study is conducted in two in-patient parts. In Part A, participants will wear three investigational devices at the same time while glucose levels are closely monitored using laboratory blood tests and a commercial CGM. This part of the study is designed to measure how basal and bolus insulin delivery near the CGM sensor affects sensor accuracy and how quickly the sensor signal recovers after insulin delivery. In Part B, participants will wear one investigational device while trained study staff use CGM information from the integrated sensor to guide insulin delivery recommendations generated by an automated glucose control algorithm. Insulin delivery decisions will be closely supervised, and glucose levels will be frequently monitored. Participants will stay at the clinical research center for short, controlled study visits. Safety will be monitored throughout the study, with predefined procedures for treating low or high blood sugar. The information collected will be used to support further development of an integrated insulin pump and CGM system for people with type 1 diabetes.
