Study on Influencing Factors of Skin Complications Related to Insulin Injection in Children With Type 1 Diabetes Mellitus

This study was a cross-sectional, observational design without involving random grouping or intervention. From July 2026 to June 2027, 199 children with type 1 diabetes who had received insulin treatment for at least 6 months and their main family caregivers were recruited by a continuous enrollment method from the endocrinology department of a tertiary children's hospital in Zhejiang Province. Qualified investigators conducted on-site distribution and collection of structured questionnaires, collecting general information of the children, the occurrence of skin complications, and the insulin injection behaviors of the caregivers. At the same time, personnel with ultrasound qualifications used a wireless handheld ultrasound combined with a skin lipid caliper to uniformly measure the subcutaneous fat thickness at 8 sites including the abdomen, buttocks, arms, and thighs.

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.

Evaluate the Performance of the Dexcom G7 Continuous Glucose Monitoring (CGM) System in Critically Ill Patients Undergoing Major Abdominal Surgery and Solid Organ Transplantation Which Require Blood Glucose Monitoring for Intensive Insulin Therapy.

Main objective: The goal is to to determine the accuracy of Dexcom G7 Continuous glucose monitor system in critically ill patients, undergoing major abdominal surgery and solid organ transplantation, in the intensive care unit. On admission to the intensive care unit or at the end of surgery, two Dexcom G7 sensors are placed in the infraclavicular position. Sensor number 1 will be blinded and will only be active when paired with the receiver, without the ability to monitor glucose levels. Sensor number 2 is used for continuous glucose monitoring and can be used to adjust the insulin dose. Patients will wear the continuous glucose monitoring sensor for a maximum of 10 days, including the time spent in the intensive care unit and the immediate care unit. The study will not interfere with any usual care clinical workflows. Calibration is only performed on an unblinded sensor. The reference method for calibration is the glucose from the blood glucose meter. Calibrate on the first day of monitoring: 4 times a day after approximately 6 hours, or if the blood glucose reading from the blood glucose meter is not within the estimated error range of the continuous glucose monitor (difference greater than 1,5mmol/L). Calibration on days 2 and 3 of monitoring: once in the morning, or when the meter's glucose reading is not within the estimated error range of the continuous glucose monitoring (difference greater than 1,5mmol/L) On subsequent days when the blood glucose meter reading is not within the estimated error range of continuous glucose monitoring (difference greater than 1,5mmol/L). Hypothesis: * Ho: No difference in mean absolute relative difference (MARD) between calibrated and non-calibrated sensors. * Ha: Calibrated sensors have lower mean absolute relative difference (δ = 4%, SD = 5%). Further objectives: To evaluate further aspects regarding the Dexcom G7 continuous glucose monitor system's performance in the intensive care unit (ICU), particularly in terms of sensitivity and specificity to detect hypo- and hyperglycaemic events, data availability, device deficiencies and safety. To identify predictive factors of the accuracy of the Dexcom G7 continuous glucose monitor system in critically ill patients in the ICU.

Pilot Study of Intrapartum Insulin Pump

People with type 1 or type 2 diabetes often use insulin pumps to manage their blood sugar during pregnancy. These pumps can help keep blood sugar in a healthy range. However, when people come to the hospital to give birth, they are often asked to stop using their insulin pump and switch to insulin given through an IV. This change can be stressful and may make blood sugar harder to control during labor. There is not enough research to know if it is safe and practical for people to keep using their insulin pump while in labor. The goal of this study is to learn whether it is safe, practical, and acceptable for pregnant people with diabetes to continue using their insulin pump during labor. The study will also look at how this approach compares to standard care, which uses IV insulin. This is a small pilot study. About 30 pregnant people with type 1 or type 2 diabetes will take part. All participants already use an insulin pump and receive care through the MedStar Diabetes in Pregnancy Program. Participants will be allowed to continue using their own insulin pump during labor, following a hospital safety plan. Their outcomes will be compared to similar patients from the past who used IV insulin during labor. The main focus of the study is to see how often people can safely stay on their insulin pump during labor and how well this approach fits into hospital care. The study will also collect information about blood sugar levels during labor and health outcomes for newborns, such as low blood sugar, breathing problems, or need for care in the neonatal intensive care unit. These outcomes are being studied to help plan future research. After delivery, participants will be asked to share their experience. This includes how satisfied they were with their diabetes care during labor, how much control they felt over their care, and how difficult or easy the treatment was to manage. Nurses and doctors will also provide feedback about caring for patients who use insulin pumps during labor. Participants will continue to check their blood sugar using continuous glucose monitoring, with fingerstick checks when needed. If any safety concerns arise, such as blood sugar levels that are too high or too low, participants will switch to standard IV insulin. This study is not meant to prove that one method is better than another. Instead, it will help researchers decide whether a larger study should be done in the future. The long-term goal is to improve diabetes care during labor and support safe, patient-centered options for people with diabetes and their babies.

Evaluation of a Mobile AI-powered Decision Support System for Insulin Dosing and Glucose Prediction in Type 1 Diabetes: The glUCModel Clinical Trial Protocol

The goal of this clinical trial is to evaluate the safety and efficacy of integrating predictive models into insulin therapy management via the user-centered glUCModel mobile app in People with Type 1 Diabetes Mellitus following Multiple Insulin Dosing therapy. Participants will be aged 18 to 65 years. The main questions it aims to answer are: Does using the app improve glycaemic control, as measured by time in range? Does using the app reduce the number of episodes of hyperglycaemia and hypoglycaemia? Are the app's design and functionality adequate? The study will comprise four phases:ses}): * Screening phase: Informed consent, collection of sociodemographic and clinical data, and baseline Pittsburg, IFIS, and DTSQ questionnaires. * Run-in phase: 2 weeks of standard care with CGM. Data will be used to generate personalized predictive models in the intervention group. * Active treatment phase: Participants continue MDI therapy. The intervention group will additionally use the glUCModel mobile app. CGM data from the final 2 weeks will be analyzed. * Evaluation and analysis phase: Participants will complete the uMARS, Pittsburgh, and DTSQ questionnaires. Statistical analysis and correlations among outcomes will be processed.
