<qa>  What is the name of the system that the investigators have created?In conjunction with Dr. Philip Payne, Chairman of the Department of Bioinformatics at The Ohio State University, the investigators have created a system for safeguarding the confidentiality and the identity of all patients who agree to participate in this research registry. Each participating institution will be responsible for de-identification of the data, using software developed by The Ohio State University, Department of Biomedical Informatics, before it is used in the registry. Each institution will confidentially maintain a code for linking this information to an individual patient.
