Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

The Evolving Landscape of Immunotoxicity: Charting Mechanisms and Future Strategies for Immune Checkpoint Inhibitor Adverse Events

Med Research, EarlyView.
ABSTRACT The use of immune checkpoint inhibitors (ICIs) has significantly improved the efficacy of cancer therapy, but their associated immune‐related adverse events (irAEs) can severely compromise treatment safety. This review systematically summarizes the core mechanisms underlying irAEs, which include multi‐organ damage resulting from T‐cell ...
