Hepatic arterial infusion of autologous CD34 cells for hepatitis C virus-related decompensated cirrhosis: A multicenter, open-label, exploratory randomized controlled trial.

Introduction: In this multicenter clinical study, we aimed to investigate the efficacy and safety of the transhepatic arterial administration of granulocyte-colony stimulating factor (G-CSF)-mobilized autologous peripheral blood (PB)-CD34 cells compared with standard therapy in patients with decompensated cirrhosis type C.

Methods: Patients were randomly assigned (2:1) to the CD34 cell transplant (CD34 cell) or standard-of-care (SOC) group and followed up for 52 weeks. The primary endpoints were the non-progression rate of Child-Pugh (CP) scores at 24 weeks post-enrollment and the safety of the protocol treatment.

Remote vital signs data monitoring during home blood transfusion: A pilot study.

Background And Aims: Our study aimed to establish safer methods to manage home blood transfusion by using a remote vital signs data monitoring system. Home care is administered for patients with various medical disorders; however, home blood transfusion remains challenging owing to the risk of transfusion-related complications.

Methods: We set up a remote vital signs data monitoring system to improve the safety of home blood transfusions.

Impact of the use of hydroxyethyl starch in granulocyte apheresis using Spectra Optia.

Objectives: To determine the impact of the use of hydroxyethyl starch (HES) in granulocyte apheresis using Spectra Optia.

Background: Granulocyte transfusion (GT) is a therapeutic option for neutropenic patients with severe bacterial or fungal infections. Recent studies in emergency medicine have shown the potential risk of using HES, which is routinely used in granulocyte apheresis to increase yield by sedimenting red blood cells.

Feasibility of six cycles of lenalidomide-based triplet induction before stem cell collection for newly diagnosed transplant-eligible multiple myeloma.

Objectives: Achieving a deep response with induction therapy has a major impact on outcomes following autologous stem cell transplantation. Although longer and intensified induction therapy may provide better disease control, longer exposure to lenalidomide negatively affects stem cell yield. We examined the feasibility of 6 cycles of lenalidomide-based triplet induction therapy before stem cell collection in transplant-eligible multiple myeloma patients.

Relationship Between Corticosteroid Dose and Muscle Oxygen Consumption in Recipients of Hematopoietic Stem-Cell Transplantation.

Introduction: After hematopoietic stem-cell transplantation (HSCT), patients exhibit decreased muscle strength and muscle oxygen consumption. Furthermore, total corticosteroid dose affects the reduction in muscle strength after HSCT. However, to date, no studies have investigated the relationship between corticosteroid dose and muscle oxygen consumption and saturation in these patients.

Relationship Between Exercise Capacity and Muscle OHb Saturation in Patients Before Hematopoietic Stem-Cell Transplantation.

Unlabelled: Patients with hematological malignancy might already have decreased muscle oxygen saturation at rest and exercise capacity before undergoing hematopoietic stem cell transplantation (HSCT). However, to date, no studies have investigated the relationship between exercise capacity and muscle oxygen saturation at rest in these patients. Therefore, purpose of this study was to investigate the relationship between exercise capacity and muscle oxygen-hemoglobin (O2Hb) saturation (SmO2) at rest and patients' hemoglobin level before undergoing HSCT.

Predictive value of interim FDG-PET/CT findings in patients with diffuse large B-cell lymphoma treated with R-CHOP.

To examine the prognostic value of interim 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) findings after 2-4 cycles of rituximab, plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with diffuse large B-cell lymphoma (DLBCL) receiving standardized treatment. After a median 3.36 years (range 0.

Safety and efficacy of amnion-derived mesenchymal stem cells (AM01) in patients with steroid-refractory acute graft-versus-host disease after allogeneic haematopoietic stem cell transplantation: a study protocol for a phase I/II Japanese trial.

Introduction: Regenerative medicine and cell therapies have been gaining much attention among clinicians. Therapeutic infusion of mesenchymal stromal cells (MSCs) is now a leading investigational strategy for the treatment of acute graft-versus-host disease (aGVHD). Bone marrow MSCs are approved for manufacture and marketing as a cell therapy for aGVHD.

Early evaluation of tumor response to Y-ibritumomab radioimmunotherapy in relapsed/refractory B cell non-Hodgkin lymphoma: what is the optimal timing for FDG-PET/CT?

Purpose: To determine the earliest optimal timing for assessment of early response following radioimmunotherapy in non-Hodgkin lymphoma patients using FDG-PET/CT.

Methods: FDG-PET/CT was performed prior to treatment (PET1), at 2 (PET2) weeks, and at 6 (PET3) weeks after Y-ibritumomab radioimmunotherapy in 55 patients. Response was evaluated based on the Deauville 5-point scale and Lugano criteria as well as semiquantitative analysis and compared with progression-free survival (PFS).

Aldehyde dehydrogenase activity in cryopreserved cord blood cells for quality assessment prior to transplantation.

In umbilical cord blood transplantation (UCBT), the number of cluster of differentiation (CD)34+ cells and colony‑forming units (CFUs) in the cord blood (CB) graft positively correlate with patient survival. Therefore, these parameters are currently used for quality assessment of the cryopreserved CB cells in the attached segment that is considered representative of the CB in the main bag prior to UCBT. Since aldehyde dehydrogenase (ALDH) activity is high in hematopoietic stem cells, the number of ALDH‑bright (ALDHbr) cells was examined in comparison with the number of CD34+ cells and CFUs for the quality assessment of CB units.

Blood supply during Japan's 1995 Hanshin-Awaji Earthquake.

On January 17, 1995, a magnitude 7.3 earthquake occurred in southern Hyogo Prefecture, a substantially urban area of Japan's main island, Honshu. Now known as the Hanshin-Awaji Earthquake, this disaster damaged or destroyed 639 686 houses and took 6434 lives.

Prospective randomized and crossover comparison of two apheresis machines for peripheral blood stem cell collection: a multicenter study.

Background: Improving apheresis technology may lead to an efficient and safe peripheral blood stem cell (PBSC) collection. Recently, the Spectra Optia (Optia, Terumo BCT) was introduced as an automated apheresis instrument, but comparisons with other instruments have been few. This is the first randomized multicenter and crossover comparison of the Optia with the automated program of the established apheresis instrument, the Spectra (Spectra-Auto, Terumo BCT).

Host Foxp3+CD4+ Regulatory T Cells Act as a Negative Regulator of Dendritic Cells in the Peritransplantation Period.

Host Foxp3+CD4+ regulatory T cells (Tregs) have been shown to suppress graft-versus-host disease (GVHD) in experimental bone marrow transplantation (BMT) models; however, the detailed mechanism is unknown. To address this issue, we established a murine MHC-haploidentical BMT model (BDF1 (H-2b/d) → B6C3F1 (H-2b/k)), in which transplantation following conditioning with high-dose (13 Gy) or low-dose (5 Gy) total body irradiation corresponds to myeloablative stem cell transplantation (MAST) or reduced-intensity stem cell transplantation (RIST) BMT. All MAST recipients died of GVHD within 70 d, whereas RIST recipients developed almost no GVHD and survived for at least 3 mo.

Update on granulocyte transfusions: accumulation of promising data, but still lack of decisive evidence.

Purpose Of Review: Inconsistent results regarding the clinical efficacy of granulocyte transfusions for the treatment or prophylaxis of life-threatening infections in neutropenic patients have been attributed to insufficient number of transfused neutrophils. Since the introduction of granulocyte colony-stimulating factor (G-CSF) to the granulocyte mobilization regimen in the 1990s, the number of transfused cells significantly increased, which directly translated to a significant increase in absolute neutrophil counts in the transfused patients.

Recent Findings: For therapeutic granulocyte transfusions, neither of the two randomized controlled studies in the G-CSF era could demonstrate a clear clinical benefit.

Inhibition of Src family kinases overcomes anoikis resistance induced by spheroid formation and facilitates cisplatin-induced apoptosis in human mesothelioma cells.

Malignant mesothelioma is an aggressive tumor arising from mesothelial cells of serous membranes, and forms spheroid-like cell aggregates in pleural and peritoneal effusions. We examined the levels of anoikis, apoptosis induced by the detachment of cells from the extracellur matrix, in suspension culture in the human mesothelioma cell line NCI-H2052. NCI-H2052 cells were adherent in conventional monolayer cultures, but were found to form spheroids in suspension cultures using dishes with ultra-low cell binding capacity.

Suppression of heme oxygenase-1 activity reduces airway hyperresponsiveness and inflammation in a mouse model of asthma.

Objective: Carbon monoxide (CO) levels in expired gas are higher in patients with bronchial asthma than in healthy individuals. Heme oxygenase-1 (HO-1) is a rate-limiting enzyme that catalyzes the degradation of heme to yield biliverdin, CO and free iron. Thus, HO-1 is implicated in the pathogenesis of bronchial asthma.

Primary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type with malakoplakia in the urinary bladder: a case report.

Primary malignant lymphoma of the urinary bladder is a rare disease constituting less than 1% of neoplasms of the urinary bladder. The most prevalent histological subtype is extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma). It is frequently associated with chronic cystitis and predominantly occurs in females.

Cell-adhesion molecule expression and the proliferation of malignant mesothelioma: a post-mortem examination.

Aim: In order to determine if metastatic malignant mesothelioma cells are more aggressive than primary malignant mesothelioma cells, an analysis of the expression of the adhesion molecules E-cadherin and β-catenin, concomitant with an assessment of the proliferative activity at primary and metastatic sites, was conducted in post-mortem samples.

Materials And Methods: E-cadherin or β-catenin expression was graded according to the percentage of positively-stained tumor cells. The proliferative activity was quantified by the Ki-67 labeling index.

Methotrexate and gemcitabine combination chemotherapy for the treatment of malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is an aggressive tumor of serosal surfaces with a poor prognosis. Methotrexate and gemcitabine have exhibited single-agent activity in MPM. We evaluated the feasibility of sequential administration of these agents in the treatment of MPM.

Soluble interleukin-2 receptor level on day 7 as a predictor of graft-versus-host disease after HLA-haploidentical stem cell transplantation using reduced-intensity conditioning.

In the present study, we analyzed the kinetics of serum soluble interleukin-2 receptor (sIL-2R) using data from 77 patients undergoing HLA-haploidentical transplantation using reduced-intensity conditioning (RIC), who were at an advanced stage or at high risk for relapse, to clarify the usefulness of sIL-2R as a biomarker of acute graft-versus-host disease (GVHD). Anti-T-lymphocyte globulin and methylprednisolone were used as GVHD prophylaxis. While the median sIL-2R in 38 patients not developing GVHD was suppressed at levels <740 U/ml, sIL-2R in 25 patients developing severe GVHD peaked on day 11 (1,663 U/ml), and thereafter decreased to <1,000 U/ml after day 30.

Recombinant human soluble thrombomodulin attenuates FK506-induced endothelial dysfunction through prevention of Akt inactivation.

Thrombomodulin (TM), a transmembrane glycoprotein on vascular endothelial cells, is a naturally occurring anticoagulant. Recombinant human soluble TM (rTM), composed of the extracellular domain of TM, also shows anti-coagulant and anti-inflammatory activity, but the effects of rTM on microangiopathy remain unclear. We reported that FK506 induced endothelial dysfunction through inactivation of Akt and extracellular-regulated kinase 1/2 using a three-dimensional culture blood vessel model.
