Transfusion

Acute upper gastrointestinal bleeding (AUGIB) accounts for 14% of all red blood cell (RBC) transfusions in the United Kingdom, despite little evidence to guide optimal blood transfusion strategies and few data on the variation in practice. We aimed to survey UK clinicians about their RBC transfusion practice in AUGIB. ⋯ There is significant variation in the reported approach to transfusion practice among clinicians caring for patients with AUGIB, with both patient- and clinician-related factors accounting for these differences. Further studies are needed to evaluate the safety and efficacy of differing blood transfusion strategies in patients presenting with AUGIB.

The dose of CD34+ cells/kg in the mobilized peripheral blood product is the main determinant of neutrophil and platelet (PLT) engraftment after autologous hematopoietic stem cell transplantation (AHSCT). Whether the method of mobilization, namely, granulocyte-colony-stimulating factor (G-CSF) alone (G), G-CSF plus plerixafor (G+P), or cyclophosphamide + G/granulocyte-macrophage (GM)-CSF (Cy+G/GM), independently affects number of colony-forming unit (CFU)-GM, engraftment, and hematopoietic graft function is unknown. ⋯ Plerixafor-based mobilization is associated with slightly reduced number of CFU-GM and minimal delay in engraftment that is independent of CD34+ cell dose. Hematopoietic graft function on Day 100 is not affected by mobilization strategy.

Warm fresh whole blood has been advocated for critical bleeding in the military setting. This study assessed whether unrefrigerated young whole blood transfusion, from donation to transfusion less than 24 hours, could reduce mortality of patients with critical bleeding in a civilian setting. ⋯ Unrefrigerated young whole blood transfusion was not associated with a reduced mortality of patients requiring massive transfusion in a civilian setting when other blood products were readily available.
