Our team visited Boston, USA, to present our results in diabetes-related research during 45th ISPAD Congress 2019, which took place from 30th October to 2nd November 2019. Beata Małachowska (MD) discussed whether Hypoglycemia leaves a persistent metabolomic fingerprint in children with type 1 diabetes during “Acute and Chronic Complications and Associated Diseases” oral session. Other works were presented as by younger members of our team: Arkadiusz Michalak, MD (Clinical characteristics of patients with HNF1B testing – Polish population study) and Jedrzej Chrzanowski (Glycemic variability assessment with continuous glucose monitoring systems demonstrates seasonal patterns in pediatric patients with type 1 diabetes mellitus). We had an amazing opportunity to meet and listen to the world`s leading researchers in the field talking about achievements and challenged of today`s diabetology for children and adolescents. The event gave us great deal of scientific inspiration and motivation to pursue our projects.
