Correlates of CRCI and Gut Microbiome Dysbiosis; a Pilot Study

Characterization of the fecal microbiome using a commercially available sampling kit and our lab's patented array for PCR at baseline

Characterization of the fecal microbiome using a commercially available sampling kit and our lab's patented array for PCR after 6 months of standard of care treatment.

The Montreal Cognitive Assessment (MoCA) is a rapid assessment of cognition. The MoCA-BLIND v8.1 will be used in this study as it can be administered in person as well as over the telephone. The MoCA-BLIND consists of 9 questions with the following subcategories: memory, attention, language, abstraction, delayed recall and orientation. The MoCA has been used extensively to detect cognitive impairment in many conditions, including head trauma. The MoCA will be administered by a certified tester at enrollment. Scores range from 0 to 22, higher score being a better outcome.

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.

The Gastrointestinal Symptom Rating Scale (GSRS) is a specific 15-item questionnaire. Subjects are asked to numerically score their subjective symptoms on a scale of 1-7 (1 = no discomfort at all; 7 = very severe discomfort) . The sum of the scores for all 15 items is regarded as the GSRS total score. Total scores range from 15 (best outcome) to 105 (worst outcome).
