Overzealous activity by mucosa-associated invariant T (MAIT) cells in response to bacterial toxins can lead to illness instead of stopping it.

Scientists can assay gene activity to distinguish between bacterial and viral infections.

An 11-gene set may help identify sepsis early, before it’s too late.

An external device that mimics the structure of a spleen can cleanse the blood of rats with acute sepsis, ridding the fluid of pathogens and toxins.

Another clinical trial raises concerns about the efficacy and safety of a common intravenous treatment for patients that have lost large amounts of blood.

The US Food and Drug Administration will consider whether or not to stop the use of intravenous starch solutions to replace lost blood.

A slight flaw in a study on the effectiveness of a drug widely used to combat shock in critically injured patients almost gets a Danish researcher sued for millions.
