Early Oral Feeding After Bowel Resection, Jennifer Strang

Theses & Dissertations

Research Focus: The primary purpose of this project was to determine if there was an association of factors with time to first solid meal in gastrointestinal (GI) surgery patients and the impact solid diet has on length of stay (LOS) in the hospital, GI symptoms, and incidence of post-operative ileus (POI). A secondary purpose was to observe and describe when an oral diet was started and the progression of diet after GI surgery.

Research Methods: This study was a cross-sectional, retrospective chart review of a convenience sample in a multi-centered hospital system conducted in 84 GI resection patients …

The factors that govern assembly of the gut microbiota are insufficiently understood. Here, we test the hypothesis that inter-individual microbiota variation can arise solely from differences in the order and timing by which the gut is colonized early in life. Experiments in which mice were inoculated in sequence either with two complex seed communities or a cocktail of four bacterial strains and a seed community revealed that colonization order influenced both the outcome of community assembly and the ecological success of individual colonizers. Historical contingency and priority effects also occurred in Rag1^-/- mice, suggesting that the adaptive immune system …

Considerations for best practices in studies of fiber or other dietary components and the intestinal microbiome. Am J Physiol Endocrinol Metab 315: E1087–E1097, 2018. First published August 21, 2018; doi:10.1152/ajpendo.00058.2018.—A 2-day workshop organized by the National Institutes of Health and U.S. Department of Agriculture included 16 presentations focused on the role of diet in alterations of the gastrointestinal microbiome, primarily that of the colon. Although thousands of research projects have been funded by U.S. federal agencies to study the intestinal microbiome of humans and a variety of animal models, only a minority addresses dietary effects, and a small subset is …
