On October 20, 2022, we hosted the 1st Cuban DOHaD Symposium, featuring distinguished speakers such as Dr. Stephen Lye, Director of the Alliance for Human Development from Canada, and Dr. Antonio Marcos de Andrade, President of the LA-Chapter DOHaD Latin America from Brazil. The event aimed to disseminate knowledge about DOHaD theories, foster shared experiences, and create opportunities for new memberships and exchanges. We were privileged to have 100 researchers and physicians from various specialties participating in this milestone event, enriching the discourse with their diverse perspectives and expertise.
