Blood Donation

The goal of this observational study is to evaluate how blood donors' lifestyle and nutritional status influence the quality of packed red blood cells (pRBCs) during storage and their impact on patient safety in transfused neonates and postpartum women. The main questions it aims to answer are: 1. Are donor lifestyle and nutritional profiles associated with the development of storage lesions in pRBCs? 2. Do these donor-related factors influence clinical outcomes after transfusion in neonates and postpartum women? 3. Are storage lesion in pRBCs associated with clinical outcomes in transfused neonates and postpartum women? Researchers will compare pRBC units stratified according to donor lifestyle and nutritional profiles to determine differences in storage lesion biomarkers and post-transfusion clinical outcomes.

"Etablissement Français du Sang" (EFS) prepares labile blood products from blood donations that are separated by type (red blood cells, plasma and platelets). The "Centre de Transfusion Sanguine des Armées" (CTSA) produces an innovative labile blood product, LTO-WB, corresponding to group O leukocyte-free whole blood. The objective of the PEDESTAL EFS study is to compare the inflammatory and biological characteristics of blood products prepared by the EFS vs. the labile blood product prepared by the CTSA.
