OBJECTIVES/GOALS: The Appalachian Translational Research Network (ATRN) Newsletter provides a unique platform that facilitates communication among Appalachian-serving CTSAs/CTSIs and partnering academic and community organizations that strengthens research efforts and advances translational science across the region. METHODS/STUDY POPULATION: Published biannually, each ATRN Newsletter features content submitted by ATRN member universities and organizations. Members of the Communications Committee, who represent both CTSA- or non-CTSA- affiliated ATRN member institutions, provide as well as review and edit content for the Newsletter. Regular features include researcher and community member spotlights; funding opportunity announcements; information on upcoming seminars, trainings, and special events; and opportunities for collaborations among partnering ATRN institutions. Complementing regularly scheduled Newsletters, special editions are released as warranted, such as a special COVID-19 focused edition published in 2020. RESULTS/ANTICIPATED RESULTS: First published in 2012, the ATRN Newsletter initially represented founding ATRN institutions, the University of Kentucky and the Ohio State University CTSAs, and a readership of 50. Reflecting ATRN growth that now represents 9 academic centers including NCATS- and IDeA-funded hubs, affiliated universities and partnering organizations, readership has grown to include 500 subscribers from across the U.S. and 3 other countries. With the establishment of the official ATRN website in 2019, the ATRN Newsletter became a prominent addition, providing ATRN members’ access to both new and archived editions, thereby expanding reach and further strengthening critical communication across the Network. DISCUSSION/SIGNIFICANCE: Providing a vehicle for communication that supports ATRN collaborations and networking, the Newsletter is foundational to the success of the ATRN mission to improve health outcomes across Appalachia by fostering collaborative inter-institutional and community-academic research partnerships.
