The Congress of Joint European Neonatal Societies (jENS) brings together three pillars of the neonatal world under a single, unified scientific platform: the European Society for Paediatric Research (ESPR), the Union of European Neonatal and Perinatal Societies (UENPS), and the Global Foundation for the Care of Newborn Infants (GFCNI). This unique alliance makes jENS Congress the most comprehensive neonatal meeting in the world — the only congress that unites scientific research, clinical excellence, and the voice of families and patients in one shared space. Newborn medicine stands at a defining moment. Rapid advances across basic science, translational research, and clinical practice are transforming what is possible in the NICU. At the same time, the challenges of extreme prematurity, global health inequity, and the growing complexity of neonatal care demand responses that no single society or discipline can provide alone. jENS was built for exactly this complexity.
