Shining a light on the hidden damage of mild brain injuries

Medical Xpress: Radiology

Researchers have created a new brain imaging method that allows mild traumatic brain injuries (mTBIs) to be diagnosed, even when existing imaging techniques like magnetic resonance imaging (MRI) don't show any structural abnormalities. The technique involves loading gadolinium, a standard MRI contrast agent, into hydrogel-based micropatches that are attached to immune cells called macrophages.

Pre-Hospital Antibiotics in Sepsis?

REBEL EM

Background: Sepsis remains one of the leading causes of morbidity and mortality. It is well-established that earlier recognition and treatment can lead to better outcome for these patients . Time to antibiotic therapy (from triage, not from onset of infection) has become a quality metric to improve the time to administration of these medications. In an effort to administer antibiotics earlier, many studies have attempted to give antibiotics in the prehospital setting but the benefit of this int

Shining a light on the hidden damage of mild brain injuries

We all know someone who's had a head injury that was 'only' a concussion, but even mild traumatic brain injuries can cause lasting damage, and the vast majority are never diagnosed. A team created a way to diagnose mild TBIs (mTBIs) even when MRI scans showed nothing, using the body's own immune cells called macrophages. They attached microparticle 'backpacks' containing a common MRI contrast agent to the cells, which migrated to the brain and allowed them to see evidence of inflammation in pigs
