Purpose: Continuous glucose monitors (CGMs) are becoming increasingly popular among endurance athletes despite unconfirmed accuracy. We assessed the concurrent validity of the FreeStyle Libre 2 worn on 2 different sites at rest, during steady-state running, and postprandial., Methods: Thirteen nondiabetic, well-trained recreational runners (age = 40 [8] y, maximal aerobic oxygen consumption = 46.1 [6.4] mL·kg-1·min-1) wore a CGM on the upper arm and chest while treadmill running for 30, 60, and 90 minutes at intensities corresponding to 50%, 60%, and 70% of maximal aerobic oxygen consumption, respectively. Glucose was measured by manually scanning CGMs and obtaining a finger-prick capillary blood glucose sample. Mean absolute relative difference, time in range, and continuous glucose Clarke error grid analysis were used to compare paired CGM and blood glucose readings., Results: Across all intensities of steady-state running, we found a mean absolute relative difference of 13.8 (10.9) for the arm and 11.4 (9.0) for the chest. The coefficient of variation exceeded 70%. Approximately 47% of arm and 50% of chest paired glucose measurements had an absolute difference ≤10%. Continuous glucose Clarke error grid analysis indicated 99.8% (arm) and 99.6% (chest) CGM data fell in clinically acceptable zones A and B. Time-in-range analysis showed reduced accuracy at lower glucose levels. However, CGMs accurately detected trends in mean glucose readings over time., Conclusions: CGMs are not valid for point glucose monitoring but appear to be valid for monitoring glucose trends during steady-state exercise. Accuracy is similar for arm and chest. Further research is needed to determine whether CGMs can detect important events such as hypoglycemia during exercise.

Background and Objectives: This educational review outlines the current landscape of pediatric anesthesia training, care delivery, and challenges across Canada, Barbados, and the United States., Descriptions and Conclusions: Approximately 5% of Canadian children undergo general anesthesia annually, administered by fellowship-trained pediatric anesthesiologists in children's hospitals, general anesthesiologists in community hospitals, or family practice anesthesiologists in underserved regions. In Canada, the focus is on national-level evaluation and accreditation of pediatric anesthesia fellowship training, addressing challenges arising from workforce shortages, particularly in remote areas. Barbados, a Caribbean nation, lacks dedicated pediatric hospitals but has provided pediatric anesthesia since 1972 through anesthetists with additional training. Challenges in its development, common to low-middle-income countries, include inadequate infrastructure and workforce shortages. Increased awareness of pediatric anesthesia as a sub-specialty could enhance perioperative care for Barbadian children. Pediatric anesthesia encompasses various specialties in the United States, with pediatric anesthesiologists playing a foundational role. Challenges faced include recruitment and retention difficulties, supply-chain shortages, and the proliferation of anesthesia sites, all impacting the delivery of modern, high-quality, and cost-effective patient care. Collaborative efforts at national and organizational levels strive to improve the quality and safety of pediatric anesthesia care in the United States., (© 2024 John Wiley & Sons Ltd.)
