Can better information increase hemapheresis?

We created a questionnaire in order to understand why donors generally did not want to give plasma and platelets the first time they were asked to donate. The hypothesis is that donors have a negative perception of hemapheresis due to insufficient information about procedures and emocomponent use. We collected 745 Questionnaires in the Marche and Abruzzo regions from February to April 2001.

Long-term hematologic reconstitution after autologous peripheral blood progenitor cell transplantation: a comparison between controlled-rate freezing and uncontrolled-rate freezing at 80 degrees C.

Background: The most widely used system for peripheral blood progenitor cell (PBPC) cryopreservation is controlled-rate freezing (CRF). Uncontrolled-rate freezing (URF) at -80 degrees C has also been used, but its clinical impact has not been studied sufficiently yet.

Study Design And Methods: Two groups of patients were compared: Group A consisted of 69 patients autotransplanted with PBPCs cryopreserved with CRF; Group B consisted of 192 patients autotransplanted with PBPCs cryopreserved with URF at -80 degrees C.
