Author Insights from Newsworthy Abstracts

ACG Public Relations Committee Chair
Nominated by the ACG Public Relations Committee, this group of abstracts features scientific findings that are innovative, newsworthy for the lay reader, relevant to those who suffer from common GI problems, and which represent a significant advancement in the diagnosis and treatment of GI diseases. The Committee aims to identify novel and thought-provoking abstracts which reinforce key public health messages, such as emerging research on GI manifestations of COVID-19, the importance of colorectal cancer screening (particularly for minority and at-risk populations), or which feature common GI problems in a new way.
