NCT03995979

Brief Summary

There is strong scientific data that supports that short-term protein restrictive diets reduce surgical stress responses. The investigators are hoping to use the information collected from the blood serum and muscle tissue of healthy subjects to help understand the baseline and early changes in muscle energetic and cell-mediated inflammation. The study team hopes to use the data collected in this pilot study to compare with patients undergoing open abdominal aortic aneurysm (AAA) repair in a future study

Outcome Measures

Primary Outcomes (1)

  • Changes in the Human Intestinal Microbiome That Result From Short Term Dietary Adjustment.

    Genomic sequencing along with taxonomic and functional pathways analysis is used to identify any compositional and functional changes in the intestinal microbiome of patients on short-term dietary restrictions in relation its anti-inflammatory effects on pre-operative conditioning,

    Day 2; Day 4; Day 7

Study Arms (1)

Protein Restriction Group

EXPERIMENTAL

Subjects will follow a 4 day protein restricted diet using Scandishake® mixed with almond milk which will be provided.

Other: 4 Day Protein Restricted Diet

Interventions

Subjects will follow a 4 day protein restricted diet using Scandishake® mixed with almond milk which will be provided. They may also drink water. No food, other beverages, or alcohol may be consumed. The amount of diet to be consumed will be calculated for each patient based upon resting energy expenditures plus additional energy needs. These will be consumed by the study subjects at home in an unrestricted manner, in that they may be consumed at any point of time in the day.

Also known as: Scandishake

Limitations and Caveats

The specific diet used in this study,although advantageous for its feasibility in achieving the targeted percent protein goal and caloric restriction, may deviate from the ideal short-term protein-calorie dietary restriction (stDR). Moreover, observations could be attributed to the diet itself and not necessarily from protein or caloric restrictions. Lastly, this study lacks a description of the peripheral immune cell response.
