A new lens on cardiac surgery could help prevent arrhythmia
Sometimes, a change in perspective can lead to a medical breakthrough. A type of microscopy typically used to detect cancer and other diseases has been adapted to reveal the location of unseen conduction tissue around the heart. The Boston Children’s clinician behind this innovation now aims to prove the safety and effectiveness of fiber-optic confocal ... Read More
A new vaccine formulation could finally protect babies against RSV
Though often mild, respiratory syncytial virus (RSV) infection can cause babies to be hospitalized with bronchiolitis or pneumonia. Globally, it is the leading cause of death in children under 5. Several vaccines against RSV are being tested in adults. But there has been no progress on an RSV vaccine for children since 1966 — the ... Read More
Chasing Rett syndrome biomarkers: Could overnight EEG studies improve care?
In Rett syndrome, a genetic condition affecting girls almost exclusively, mutations in the MECP2 gene cause a regression of language and motor skills starting at 12-to-18 months of age. Children then usually stabilize, but how Rett will ultimately affect them is hard to predict. Some girls develop epilepsy; others have no seizures at all. Language, ... Read More
A potential danger of CRISPR gene editing — and why base editing may be safer
Gene therapy using CRISPR/Cas9 gene editing is currently in clinical trials around the world for a variety of diseases, including various cancers, blood disorders, and metabolic disorders. It works by making cuts in DNA — both strands of the double helix — to insert or remove genes. But CRISPR carries a potential, previously undiscovered danger, ... Read More
New work transforms our knowledge of how blood is formed
The origins of our blood may not be quite what we thought. In groundbreaking research, scientists in the Stem Cell Program at Boston Children’s Hospital used cellular “barcoding” techniques in mice to track the development of blood in real time — and found that blood cells originate not from one type of mother cell, but ...

Genomic ‘fingerprinting’ yields better treatments for pediatric solid cancers
Genomic profiling is increasingly used for solid tumors in adults and for pediatric brain tumors and blood cancers, allowing treatments to be matched to patients’ mutations. But for children with solid tumors, genomic fingerprinting has been elusive, because these cancers are so varied and individually so rare. Therapies therefore remain non-specific: chemotherapy, surgery, and/or radiation. ... Read More
