Pathological Myeloid Activation After Sepsis and Trauma
Recruiting now
Conditions studied: Trauma Injury, Sepsis, Immunosuppression, Chronic Critical Illness
In brief
The goal of this observational study is to better understand what happens to circulating blood after a patient experiences severe trauma injury. The main questions it aims to answer are: Is severe human trauma associated with specific patterns of development in the hematopoietic stem cells of these patients? and Does the initial severe trauma injury create immunosuppression and increase risk of in-hospital sepsis? Participants in study will give blood samples and a waste sample of bone marrow at time of operative repair of traumatic orthopedic injuries, supply medical information and participate in surveys and assessments during recovery from their injury(ies). Researchers will compare severe trauma injury patients to elective hip repair patients to see if immunosuppression and specific development patterns occur in the trauma patient versus the otherwise healthy hip surgery patient.
