WEEKLY COMMUNITY CALL MEETING
The 2026 Global Symposium Collaborator Showcase welcomed a record number of posters and software demos from our global community, and following a vote from symposium registrants, these four submissions earned Best Community Contribution Awards.
Clinical Application (#22): Why cancer phenotypes in RWE studies are often wrong? (Asieh Golozar)
Methodological Research (#162): UNO: Neural Pruning Enhances AI Reliability of Observational Data-based Findings (Yue Wu)
Open-Source Development (#138): OCL Mapper and the CIEL Bridge: Open-Source, AI-Assisted Mapping of Clinical Concepts to Standard Vocabularies and OMOP (Jonathan Payne)
Data Standards (#95): OMOP ETL Design for Transparency, Quality, and Maintainability (Natasha Flowers)
Please join our Nov. 10 community call (11 am ET) as the lead authors of these respective research presentations share their work with our global community.
Everybody is invited. If you didn’t receive a call invite, please use this link to join. The call schedule and previous recordings can be found on the community calls page.

OHDSI UPDATES
The latest edition of the OHDSI newsletter is now available, and it includes a review and key links from the Global Symposium, spotlights on two of our Asia-Pacific leaders, community updates, recent publications and presentations, and more.
• Materials from the 2026 Global Symposium will be available on the event homepage when available. Currently all talks from the main conference, as well as the showcase posters and demos, are available.
• Jiwon Um began her career in clinical psychology, working with children and their families. Today she studies how mothers’ cardiovascular-kidney-metabolic health takes shape across populations, as a data scientist at Yonsei University Health System and a PhD candidate in Biomedical Systems Informatics at Yonsei University College of Medicine, advised by Dr. Seng Chan You. She is a fellow in the Johns Hopkins Maternal Health Fellowship (2026–2028). Within OHDSI, she serves as the APAC Community Coordinator, leading the monthly APAC Community Calls. She also contributes to network studies including CHRONICLE-DM and is part of the organizing team for the 2026 APAC Symposium. Jiwon discusses how OHDSI has impacted her educational journey, child and adolescent development research, OHDSI and its relationship with medical AI, and more in the latest Collaborator Spotlight.
• The OHDSI website received a complete refresh prior to the symposium. There are new pages devoted to the work OHDSI does, as well as the similar links to community forums, workgroups, community calls, and more.
• The 2026 version of the Our Journey annual report (fifth edition) is available via PDF on the OHDSI website.
• A new call for papers is open for a Journal of Biomedical Informatics special issue focusing on agentic AI for generating trustworthy Real-World Evidence (RWE). The issue seeks contributions on multi-agent collaboration and coordinated autonomy across the RWE lifecycle—such as data harmonization and causal analysis—while excluding single-task AI agents. Submissions are accepted from June 15 through November 15, 2026, with publication slated for September 2027.
