Fatigue and Cognition as measured by the Fatigue and Altered Cognition Scale at baseline
The Fatigue and Altered Cognition Scale (FACS) is a joint project from University of Texas Medical Branch and Texas A\&M University. The FACS is a 20 question assessment designed to access perceived fatigue and cognition. There are 2 subscales used to calculate a total score. The subscales are: Fatigue and Altered Cognition. The total score is calculated by adding the subscales together. The range of the total score is 0-100, with a higher score indicating more fatigue and altered cognition.

Quantify absolute abundance of gut microbiome using using metagenomic analysis at baseline
Metagenomic analysis using a custom PCR array will be performed on stool samples to identify associated changes in microbiome absolute abundance at the genus and species level.
