The International Severe Asthma Registry (ISAR) was established in 2017 to advance the understanding of severe asthma and its management, thereby improving patient care worldwide. As the first global registry for adults with severe asthma, ISAR enabled individual registries to standardize and pool their data, creating a comprehensive, harmonized dataset with sufficient statistical power to address key research questions and knowledge gaps. Today, ISAR is the largest repository of real-world data on severe asthma, curating data on nearly 35,000 patients from 28 countries worldwide, and has become a leading contributor to severe asthma research. Research using ISAR data has provided valuable insights on the characteristics of severe asthma, its burdens and risk factors, real-world treatment effectiveness, and barriers to specialist care, which are collectively informing improved asthma management. Besides changing clinical thinking via research, ISAR aims to advance real-world practice through initiatives that improve registry data quality and severe asthma care. In 2024, ISAR refined essential research variables to enhance data quality and launched a web-based data acquisition and reporting system (QISAR), which integrates data collection with clinical consultations and enables longitudinal data tracking at patient, center, and population levels. Quality improvement priorities include collecting standardized data during consultations and tracking and optimizing patient journeys via QISAR and integrating primary/secondary care pathways to expedite specialist severe asthma management and facilitate clinical trial recruitment. ISAR envisions a future in which timely specialist referral and initiation of biologic therapy can obviate long-term systemic corticosteroid use and enable more patients to achieve remission.

Two rehydration protocols currently exist to treat diabetic ketoacidosis (DKA) in pediatric patients aged <21 years: the traditional “one-bag” system and the more recent “two-bag” system. This study aimed to evaluate the safety and efficacy of the newer two-bag system versus the well-established one-bag system. The CiNAHL, Cochrane Library, Embase, PubMed, Scopus, and Web of Science databases were comprehensively searched from inception to June 2023 by 2 independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis framework. Eligible studies were those that reported participants <21 years of age who presented to the emergency room with a clinical diagnosis of DKA. This review was prospectively registered on PROSPERO (CRD42023427551). From the initial screening of 42 studies, 8 unique studies encompassing 583 patients met the eligibility criteria. The analysis yielded no significant intergroup differences in hypoglycemia (odds ratio, 0.61; 95% confidence interval [CI], 0.20–1.87; I2=3%) or mean glucose correction rate (mean difference [MD], 0.04 mg/ dL/hr; 95% CI, -13.10 to 13.17; I2=64%). The incidence of cerebral edema was as low (0.17%) across groups, with only one case reported in the one-bag group. Notably, the mean time to DKA resolution (MD, -3.24 h; 95% CI, -5.57 to -0.91; I2=0%) and mean response time for intravenous fluid changes (MD, -32.75 min; 95% CI, -43.21 to -22.29; I2=59%) was lower for the two-bag system. This meta- analysis presents preliminary evidence suggesting that the two-bag system may confer advantages over the one-bag system for selected patients. However, further studies with greater patient stratification based on DKA severity, fluid composition, and protocol are needed to draw definitive conclusions and elucidate the extent of these advantages.
