This edition focuses on two of my colleagues from the UCL Institute of Child Health, Professor Monty Mythen and Dr Mike Grocott.
They recently lead a ground-breaking medical study to Mount Everest, which included taking nine healthy children to the world's highest mountain, with the aim to develop new treatments for critically ill children.
This specialist briefing explains how by studying the way the children's bodies coped and adapted at altitude, doctors and scientists from Great Ormond Street Hospital and its research partner, UCL Institute of Child Health, hope to improve the chances of survival for children in intensive care units.
Professor Martin Elliott MD FRCS, Professor of cardio-thoracic surgery and chairman of Cardiac Services.
