CD34(+)-selected stem cell boost without further conditioning for poor graft function after allogeneic stem cell transplantation in patients with hematological malignancies.

We retrospectively analyzed outcomes of a CD34(+)-selected stem cell boost (SCB) without prior conditioning in 32 patients (male/22; median age of 54 years; range, 20 to 69) with poor graft function, defined as neutrophils ≤1.5 x 10(9)/L, and/or platelets ≤30 x 10(9)/L, and/or hemoglobin ≤8.5 g/dL).

Purification of CD4+ T cells for adoptive immunotherapy after allogeneic hematopoietic stem cell transplantation.

Donor lymphocyte infusions (DLIs) are used for adoptive immunotherapy to prevent or treat relapse and infectious complications after allogeneic hematopoietic stem cell transplantation (HSCT). Unmanipulated DLIs are associated with a risk of graft-versus-host disease (GVHD), probably related to CD8(+) T cell activity. We investigated an automated clinical-scale human-CD4(+)-cell purification method to deplete CD8(+) cells.

Prevention of dislocation in total hip revision surgery using a dual mobility design.

Background: Postoperative dislocation is the commonest complication following revision total hip arthroplasty (THA). HYPOTHESIS AND TYPE OF STUDY: Dual mobility cups are supposed to reduce the risk of THA instability. The present retrospective study tested this hypothesis on revision THAs and also, assessed this design contribution to acetabular fixation longevity.

[Oxygen affinity and regeneration capacity of SAG-M and PAGGS-M stored erythrocytes].

In order to estimate the leftward shift of the oxygen dissociation curve of hemoglobin following storage of red blood cells (rbc) in the additive solutions SAG-M and PAGGS-M, respectively, we performed blood gas analyses after equilibrating the cells with a gas mixture containing 4% of O2 and 5% of CO2 at pH 7.4 and 37 degrees C. Additionally, we took advantage of these nearly physiological conditions to measure the recovery of the hemoglobin function in vitro.
