The AAP Program Committee recognizes that the results of some original and exciting scientific research were not available by the deadline for the general abstract deadline in September. For the first time the AAP offers a call for late-breaking abstracts that highlight novel and substantive studies of high importance to be presented at the 2016 AAP Annual Meeting in Sacramento, CA, February 18-20, 2016. The presenting author, of an accepted abstract, is required to attend the 2016 AAP Annual Meeting in order to present the accepted abstract. If for whatever reason none of the authors are able to attend the abstract will be withdrawn. Thank you, AAP Staff
