The increased use of Peripheral Blood Stem Cells (PBSC) to reconstitute hematopoiesis in autotransplant and, more recently, allotransplant settings has not been associated with a consensus means to quality control the PBSC product. Since the small population of cells that bear the CD34 antigen are thought to be responsible for multilineage engraftment,(More)
In concert with the International Society of Hematotherapy and Graft Engineering (ISHAGE), we previously described a set of guidelines for detection of CD34+ cells based on a four-parameter flow cytometry method (CD45 FITC/CD34 PE staining, side and forward angle light scatter). With this procedure, an absolute CD34+ count is generated by incorporating the(More)
Flaxseed is rich in alpha-linolenic acid (alpha-LA) which has anti-atherogenic properties, and lignans which are platelet activating factor (PAF)-receptor antagonists. These constituents of flaxseed, and its beneficial effects in the MRL/lpr lupus mouse prompted us to perform this dosing study in lupus nephritis patients. Nine patients were enrolled, eight(More)
Reduced CD34(+) cell viability due to cryopreservation has unknown effects on subsequent hematopoietic engraftment in autologous transplantation. Thirty-six consecutive autologous peripheral stem cell collections were analyzed for absolute viable CD34(+) cell numbers at the time of stem cell collection and prior to re-infusion. Viable CD34(+) cells were(More)
BACKGROUND Circulating tumor cells (CTCs) in the peripheral blood of breast cancer patients may be an important indicator of metastatic disease and poor prognosis. However, the use of experimental models is required to fully elucidate the functional consequences of CTCs. The purpose of this study was to optimize the sensitivity of multiparameter flow(More)
Standard treatment for venous thromboembolism is parenteral heparin followed by warfarin. In this study we assess whether a standardized method of ordering warfarin reduces the duration of hospitalization. Consecutive patients were randomized to receive warfarin managed by attending physicians or by a nomogram. Patients were stratified according to primary(More)
OBJECTIVE To review the literature on red blood cell storage and its relationship to the efficacy of transfusion. RESULTS Well-documented changes occur to the red blood cell product during ex vivo storage. These changes include a reduction in red blood cell deformability, altered red blood cell adhesiveness and aggregability, and a reduction in(More)
CONTEXT Benefits of recombinant activated factor VII (rFVIIa) in hemorrhage may be lost because of thromboembolic events (TAE). METHOD MEDLINE, EMBASE, BIOSIS, CINAHL, Science Citation Index Expanded, clinicaltrials.gov were searched for placebo controlled trials of rFVIIa in patients without hemophilia. Reports of 22 randomized controlled trials were(More)
The clinical consequences of prolonged storage of red cells have not been established. In this pilot study, we evaluated whether it would be feasible to provide a continuous supply of red cells stored <8 days. In addition, we examined the potential benefits attributed to "fresh" as compared to standard red cells in 66 critically ill and cardiac surgical(More)
