Therefore, close monitoring of glucose levels is crucial. Data demonstrated that capillary measurement methods underreport hyperglycemic episodes compared with continuous glucose monitoring (CGM). However, the accuracy of CGM during intensive hematological treatments, and the associated metabolic and hemostatic imbalances, is unknown, which we aim to investigate in the current study. <b><i>Methods:</i></b> For the analysis, data collected during a prospective study that compared CGM with capillary point-of-care (POC) glucose measurements in adult patients hospitalized for intensive hematological care with three different treatment modalities, namely chimeric antigen receptor T-cell therapy, allogeneic stem cell transplantation (allo-SCT), or autologous stem cell transplantation (auto-SCT), were used. POC and CGM measurements were performed concurrently.

The development of insulin pumps, continuous glucose monitoring systems, and automated insulin delivery (AID) systems has enabled people living with T1D to safely manage their glucose, reduce their HbA1c, and improve their overall health and quality of life. Nevertheless, AID systems are not yet designed for all people with T1D, and they perform best during the overnight period when meals and exercise are not occurring. AID systems are not fully automated in that they require the person using the system to announce meals and exercise to the system to avoid dangerous hyper- or hypoglycemia, respectively. In this review, which is one of a collection of articles to commemorate the 75th anniversary of the National Institute for Diabetes and Digestive and Kidney Diseases, we celebrate the commercialization of the AID and discuss the major challenges and research gaps that remain to be solved to enable single- and multihormone AID systems to more fully support glucose management in people living with T1D. More research is required to design and evaluate more intelligent AID systems that do not require accurate carbohydrate estimations or announcements for meals and exercise. Current AID systems are also not designed to be used by older adults or pregnant people. Results are presented on new AID systems that can automatically respond to meals and exercise. Results are also presented on evaluations of AID systems in older adults and pregnant people. Next-generation AID systems will need to support all people, including older adults, people during pregnancy, athletes, and people who may be too busy to announce carbohydrates or exercise to the system.
