Appendicitis is a painful swelling and infection of the appendix. The appendix is a fingerlike pouch attached to the large intestine and located in the lower right area of the abdomen. Scientists are not sure what the appendix does, if anything, but removing it does not appear to affect a person’s health. The inside of the appendix is called the appendiceal lumen. Mucus created by the appendix travels through the appendiceal lumen and empties into the large intestine.
The first study to compare molecular landscapes of early-onset and late-onset appendiceal cancer has revealed distinct non-silent mutations in the tumors of younger patients, setting the stage for the development of potential therapeutic advances for this rare disease.
There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals.
