BACKGROUND: Red blood cell (RBC) transfusion can be life-saving; however, the risks of RBC transfusion have been increasingly recognized, and current guidelines recommend restrictive transfusion in most patients. We hypothesized that RBC transfusions are decreasing in surgical patients. STUDY DESIGN AND METHODS: A retrospective review of the National Surgical Quality Improvement Program database was performed from 2011 to 2015. Index cases in five surgical specialties were studied: neurosurgery, thoracic surgery, gynecologic surgery, orthopedic surgery, and vascular surgery...

BACKGROUND: Cancer immunotherapy involving natural killer (NK) cells has gained interest. Here we report two methods to obtain interleukin (IL)-15-activated NK cells for clinical use. STUDY DESIGN AND METHODS: IL-15-activated NK cell products were obtained after 1) enrichment from healthy haploidentical donors' peripheral blood mononuclear cells (PBMNCs) collected by nonmobilized apheresis by a two-step magnetic procedure, depletion of CD3+ cells followed by selection of CD56+ cells and ex vivo overnight stimulation with IL-15 (NKIL15); and 2) expansion using the K562-mb15-41BBL cell line (NKAE), from autologous PBMNCs from patients with multiple myeloma or expansion from healthy haploidentical PBMNCs obtained from whole blood using the same previous cell line...

BACKGROUND: The composition of the graft used for allogeneic hematopoietic stem cell transplantation (HSCT) is important for the treatment outcome. Different apheresis devices may yield significant differences in peripheral blood stem cell graft cellular composition. We compared stem cell grafts produced by Cobe Spectra (Cobe) and Spectra Optia (Optia) with use of the mononuclear cell (MNC) protocol, and evaluated clinical outcome parameters such as graft-versus-host disease (GvHD), transplant-related mortality (TRM), relapse, and overall survival...

BACKGROUND: The first step in the production of chimeric antigen receptor T cells is the collection of autologous T cells using apheresis technology. The procedure is technically challenging, because patients often have low leukocyte counts and are heavily pretreated with multiple lines of chemotherapy, marrow transplantation, and/or radiotherapy. Here, we report our experience of collecting T lymphocytes for chimeric antigen receptor T-cell manufacturing in pediatric and young adult patients with leukemia, non-Hodgkin lymphoma, or neuroblastoma...

BACKGROUND: Recent advances in massively parallel sequencing (MPS) technology have provided efficient methods for noninvasive prenatal paternity testing (NIPAT). However, a well-accepted protocol has not been established. The present study developed an MPS-based approach for NIPAT and compared the performance of two recently reported methods for MPS data interpretation. STUDY DESIGN AND METHODS: We selected 1795 unlinked polymorphic single-nucleotide polymorphisms (SNPs) and performed paternity analysis in 34 real parentage test cases with maternal plasma samples using the Illumina HiSeq platform...

BACKGROUND: Allogeneic natural killer (NK) cell adoptive immunotherapy is a growing therapeutic option for patients. Clinical-scale production of NK cells using immunomagnetic selection complies with current good manufacturing practices (cGMPs) and allows for closed-system, automated purification. We report our experience with CD3/CD19 cell-depleted (CD3/CD19dep ) NK cell production and compare to previous methods of CD3 cell depletion and CD3 cell depletion/CD56 cell enrichment. STUDY DESIGN AND METHODS: Nonmobilized mononuclear cells collected by apheresis were incubated with anti-CD3/anti-CD19 microbeads and depleted in an automated cell selection system (CliniMACS, Miltenyi)...

BACKGROUND: The successful introduction of prophylaxis with anti-RhD immunoglobulin has resulted in a significant decline of pregnancy-related RhD immunizations but also has decreased the availability of naturally immunized women as (new) anti-D donors. An influx of new donors is necessary to maintain a sufficient pool of anti-D donors. We investigated motivators, barriers, and predictors for anti-D donorship in RhD-immunized women. STUDY DESIGN AND METHODS: A mixed-methods design was applied, including focus group discussions and questionnaires...

BACKGROUND: Human babesiosis is caused mainly by Babesia microti and has recently become a public health concern due to an increase in transfusion-transmitted infection. Thus, the development of an antibody detection method with high specificity and sensitivity is a priority. Seroreactivity against B. microti has been reported to be highly specific not only to B. microti lineages but also to sublineages. This study aimed to elucidate the human antibody reactivity against various lineages, including US, Kobe, and Hobetsu, and sublineages (North America and East Asia) in the US lineage...

BACKGROUND: Whole blood and red blood cell (RBC) donors are at risk of iron deficiency. Since Source plasma (SP) donors have RBCs returned during apheresis, risk of iron depletion appears low. However, SP donors can donate frequently and assessment of frequent donor iron status is needed. STUDY DESIGN AND METHODS: A total of 1254 SP donors were enrolled in four frequency groups determined by donations in the prior 12 months: no donations and 1 to 24, 25 to 69, and 70 or more donations...

BACKGROUND: Cord blood units (CBUs) are processed, frozen, and thawed before use in hematopoietic stem cell (HSC) transplantation. The manipulations affect HSC functionality, that is, induce apoptosis and reduce viability. HSC content, commonly expressed as CBU potency, that is, the expected ability of a CBU to restore hematopoiesis, is traditionally approximated through viable CD34+ cells and the colony-forming unit (CFU) cell cultivation assay. Alternative approaches, for example, the aldehyde dehydrogenase (ALDH) enzyme-based assay, are also forthcoming...

BACKGROUND: Bacterial contamination of cord blood (CB) represents a safety risk for transplantation patients. CB sterility testing at Canadian Blood Services' Cord Blood Bank is performed using a 1:1 mix of CB-derived plasma and red blood cells (RBCs). Culture bottles of an automated culture system, which lack antimicrobial neutralization properties, are used for bacterial screening of CB. This process is unsuitable for CB-containing antibiotics, potentially resulting in false-negative results...
