Microbiome Dysfunction in Surgical Intensive Care Unit Survivors Subtitle: The Role of Brain-Bone Marrow-Gut Interaction Following Major Trauma Pathological Myeloid Activation After Sepsis and Trauma
University of Florida
Summary
Oral and gastrointestinal microbiome dysfunction has been demonstrated to be a culprit of various systemic dysfunctions in peripheries such as cardiovascular, nervous, endocrine and musculoskeletal systems. The topic of microbiome dysfunction after surgical intensive care admission is understudied but may be responsible for persistent systemic inflammation clinically observed in surgical intensive care patients. Therefore, the objective of this project is to investigate the oral and gut microbiome after the acute phase of sepsis, severe trauma injury, cardiopulmonary bypass, and major vascular surgery to compare with 108 age-matched healthy population controls
Description
The investigators hypothesize that alterations of the oral and gut microbiota will correlate with persistent systemic inflammation in surgical intensive care unit survivors compared to existing healthy population controls. This research group will collect oral and stool samples from 108 sepsis survivors, 108 trauma survivors, 108 cardiopulmonary bypass survivors, and major vascular surgery survivors (groups of ages 18-45, 46-64, and \>65; male and female; n=18 per age + sex cohort) admitted to the surgical intensive care unit between day 7 and 28 of hospital admission, as well as 3 and 6 month…
