BACKGROUND: Studies in murine models suggested that platelet desialylation was an important mechanism of thrombocytopenia during sepsis. METHODS: First, we performed a prospective, multicenter, observational study that enrolled septic patients with or without thrombocytopenia to determine the association between platelet desialylation and thrombocytopenia in patients with sepsis, severe sepsis, and septic shock. Gender- and age-matched healthy adults were selected as normal controls in analysis of the platelet desialylation levels (study I)...

Human umbilical cord blood-derived endothelial progenitor cells (EPCs) have been proven to contribute to post-natal angiogenesis, and have been applied in various models of ischemia. However, to date, to the best of our knowledge, there is no available data on the angiogenic properties of EPCs during the process of in vitro expansion. In this study, we expanded EPCs to obtain cells at different passages, and analyzed their cellular properties and angiogenic ability. In the process of expansion, no changes were observed in cell cobblestone-like morphology, apoptotic rate and telomere length...

Mitogen-activated protein kinases (MAPKs) signaling cascades regulate several cellular functions, including differentiation, proliferation, survival, and apoptosis. The duration and magnitude of phosphorylation of these MAPKs are decisive determinants of their physiological functions. Dual-specificity phosphatases exert kinetic control over these signaling cascades. Previously, we demonstrated that DUSP4(-/-) hearts sustain a larger infarct and have poor functional recovery, when isolated hearts were subjected to ischemia/reperfusion...

INTRODUCTION: Leptospirosis is a zoonotic infection that typically presents with fever, myalgias, nausea, and vomiting after contact with contaminated waters or infected animals (typically rodents); and their excrements. Conditions favorable to the transmission of leptospirosis are common in LA and, without treatment, leptospirosis can lead to both liver and renal failure, meningitis, pulmonary hemorrhage and ultimately death. CASE: A 56 year old woman with no past medical history presented to the Emergency Department with weakness, myalgias, jaundice and decreased urine output for one week...

A 56-year-old Japanese man with liver cirrhosis (LC) due to hepatitis C virus was admitted to our hospital for radiofrequency ablation of residual tumor following lusutrombopag administration. Laboratory tests revealed thrombocytopenia and leukopenia. The patient's LC was managed, and he was classified as Child-Pugh A. After admission, lusutrombopag was administered for 7 days. The platelet count increased to over 50,000/mm(3) after 7-14 days and returned to previous levels 50 days after administration. Leukocyte and erythrocyte counts also increased in response to the treatment and stayed elevated for over 120 days...

BACKGROUND: Upper-extremity transplantation (UET) is a reality. Immunologic, functional, and graft survival outcomes have been encouraging. However, these complex reconstructions have unique considerations that pose distinct challenges. Transplant programs have reported morbidity and mortality due to significant intraoperative blood losses, but similar data are scant during other phases of recovery. We report experience from two centers on complete blood component demands and utilization with UET...

INTRODUCTION: Increase in awareness regarding use of single donor platelets and the availability of technology has resulted in increased platelet pheresis procedures. The interval between two succesive plateletpheresis donations is much less compared to whole blood donations. Plateletpheresis procedures are associated with short term and long term adverse events. The effect of plateletpheresis on haematopoietic system remains significant. AIM: To study the recovery of platelet count to baseline in plateletpheresis donors...

BACKGROUND: Septic shock is a severe complication in polytrauma patients. Early identification of patients at risk can guide future prevention strategies. Platelets (PLTs) and leucocytes presumably play an important role in the post-injury inflammatory response. The role of early changes in PLT and leucocyte counts was investigated in search for the aetiology of the development of septic complications. METHODS: Polytrauma patients (aged 16-80 years) admitted to the intensive care unit with an expected stay of at least 3 days were included...

Intrabone marrow cord blood transplantation (IB-CBT) was proposed as a promising treatment modality to improve hematological recovery. However, clinical advantages of IB-CBT over conventional IV CBT have been unclear. We conducted a prospective single-center trial of IB-CBT to evaluate its safety and superiority in terms of hematological recovery. Fifteen adults with hematological malignancies were enrolled. A thawed and unwashed single cord blood unit was injected into the bilateral superior-posterior iliac crests under local anesthesia...

Peripheral blood stem cells (PBSCs) are widely used for autologous blood stem cell transplantation (ABSCT). These cells must be stored for months or even years, usually at temperatures ≤-140°C, until their use. Although several in vitro studies on CD34(+) viability and clonogenic assays of PBSCs after long-term storage have been reported, only a few publications have investigated the influence of long-term storage on in vivo hematopoietic reconstitution. In this study, we retrospectively analyzed hematopoietic recovery after storage of PBSCs via controlled-rate freezing (CRF) and cryostorage in 10% DMSO at ≤-140°C in 105 patients with multiple myeloma who received high-dose melphalan before ABSCT...
