Recent advances in pediatric medicine focus on precision diagnostics and treatment improvements. Collaborations among Boston Children’s Hospital, Dana-Farber, and Broad Institute launched integrated genomic profiling for pediatric cancers, enhancing prognostic accuracy. Novel biomarkers and imaging techniques, including functional echocardiography and new neuroimaging indices, improve management of neonatal shock and neurodegenerative diseases. Research highlights also include the impact of early pregnancy depression on toddler allergies, and innovations in NICU care addressing racial disparities and mental health challenges, pointing toward more tailored and equitable pediatric health services.
