Does metaplastic polyp of the colon develop in response to inflammation?
The factors responsible for the formation of non-neoplastic metaplastic polyps larger than 5 mm with a protruding morphology are: an increased number of epithelial cells due to the movement of these cells toward the ductal epithelium in the proliferating zone; and expansion of interstitial tissues due to infiltration of myofibroblasts and other inflammatory cells in response to inflammation.
Isotopic estimates of sugar intake were not associated with obesity, but were adversely associated with other chronic disease risk factors in this Yup'ik study population. This first use of stable isotope markers of sugar intake may influence recommendations for sugar intake by Yup'ik people; however, longitudinal studies are required to understand associations with chronic disease incidence.
