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.

Background:
Changes in cognitive function are associated with increased depression and decreased quality of life (QOL). This study aimed to determine the relationship between the characteristics of geriatric patients and anesthetic management with changes in postoperative cognitive function and QOL of geriatric patients undergoing elective surgery.
Methods:
This prospective observational analytic multicenter study included patients aged ≥60 years who underwent elective surgery in hospitals in Indonesia. We used the whole sampling method and performed follow-up 30 days after surgery. Data were analyzed using bivariate chi-square and multivariate regression tests with a confidence interval of 95% and α=5%.
Results:
Among the 933 geriatric patients included in this study 55.0%, females most (59.8%) received general anesthesia. Factors including age (p<0.001, B=-0.374, odds ratio [OR]=0.688), body mass index (BMI) (p<0.05, B=0.129, OR=1.138), and physical status based on American Society of Anesthesiologists (ASA) classification (p<0.001, B=-0.458, OR=0.633) were significantly associated with postoperative cognitive function. BMI (p<0.001, B=-0.218, OR=1.244), absence of comorbidities (p<0.05, B=-0.312, OR=0.732), regional anesthesia (p<0.05, B=0.606, OR=1.883), and changes in cognitive function (p<0.05, B=0.288, OR=1.334) were significantly correlated with changes in postoperative QOL.
Conclusion
Age, BMI, and ASA physical status were significantly associated with postoperative cognitive function in geriatric patients, whereas BMI, comorbidities, regional anesthesia, and changes in postoperative cognitive function were associated with QOL. These preoperative factors can predict postoperative cognitive function and QOL and may be useful during preoperative planning.

Poly(ADP-ribose) polymerase 1 (PARP1) is a multifunctional protein involved in diverse cellular functions, notably DNA damage repair. Pharmacological inhibition of PARP1 has therapeutic benefits for various pathologies. Despite the increased use of PARP inhibitors, challenges persist in achieving PARP1 selectivity and effective blood-brain barrier (BBB) penetration. The development of a PARP1-specific positron emission tomography (PET) radioligand is crucial for understanding disease biology and performing target occupancy studies, which may aid in the development of PARP1-specific inhibitors. In this study, we leverage the recently identified PARP1 inhibitor, AZD9574, to introduce the design and development of its 18F-isotopologue ([18F]AZD9574). Our comprehensive approach, encompassing pharmacological, cellular, autoradiographic, and <i>in vivoi> PET imaging evaluations in non-human primates, demonstrates the capacity of [18F]AZD9574 to specifically bind to PARP1 and to successfully penetrate the BBB. These findings position [18F]AZD9574 as a viable molecular imaging tool, poised to facilitate the exploration of pathophysiological changes in PARP1 tissue abundance across various diseases.
