Science Education: Physical Trauma and Sepsis
Studies on physical trauma and sepsis, the body's overwhelming immune response to severe injury or infection, focus on questions like:
- What changes occur immediately and over time when a person is critically ill or injured?
- Why does the immune system go into overdrive?
- How can we improve diagnosis and treatment strategies?

Dormant Viruses Reactivate, Signaling Effect of Lingering Sepsis
People with sepsis have higher levels of certain viruses that may suppress the immune systemís ability to defend against the viruses and other infections.
Study Comparing Sepsis Treatment Methods Shows Equivalent Survival Rates
A clinical study comparing three treatment methods for sepsis showed that patients did equally well regardless of which method was used.
Protein Triggers Inflammatory Responses in Hemorrhage and Sepsis
Blocking the activity of a protein that triggers inflammatory responses during hemorrhagic shock and sepsis decreased mortality in a mouse study.
Improving the Odds of Surviving Sepsis
Sepsis is an overwhelming immune response to infection that can lead to organ failure. Recent research focuses on detecting it early, treating it quickly and reducing its later effects.
