Thank you to Drs Sago, Ito and Isayama for a wonderful  visit to Tokyo’s National Centre for Children’s Health and Development (NCCHD)! I enjoyed learning more about each of your research along with Dr Tomo Suzuki’s. Congratulations on your new evidence-based approach to PTB management! I enjoyed the opportunity to speak with your colleagues in Neonatology, Obstetrics, Ob Medicine, Ob Anesthesia, Pharmacology and your trainees!
