Despite the curative potential of allogeneic stem cell transplantation (allo-SCT) in patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), many patients will relapse. Until recently therapeutic options mainly consisted of palliative care, chemotherapy, donor lymphocyte infusions and second transplantation in selected cases. Still many patients either do not tolerate intensive therapies or do not achieve durable remissions and will finally succumb. Given this unmet medical need the hypomethylating agents (HMA), Azacitidine (Aza) and Decitabine (DAC) have been tested as salvage therapy in patients with myeloid malignancies relapsing after allo-SCT...

BACKGROUND: Salvage regimens for patients with relapsed/refractory acute myeloid leukemia (rrAML) lack comparative data for superiority. Thus, we conducted a retrospective analysis of clofarabine-based (GCLAC; granulocyte colony-stimulating factor [filgrastim], clofarabine, high-dose cytarabine) versus cladribine-based (CLAG; cladribine, cytarabine, granulocyte colony-stimulating factor [filgrastim]) regimens in rrAML. PATIENTS AND METHODS: We identified 41 consecutive patients with rrAML who had received either GCLAC or CLAG from 2011 to 2014...

Surgical methods for type II odontoid fracture can be classified into 2 main groups: anterior or posterior approach. A more effective way to achieve bone fusion with the lowest possible surgical risk is needed. Therefore, the aim of our study was to describe and evaluate a novel technique, cable-dragged reduction/cantilever beam internal fixation for the treatment of type II odontoid fracture.This was a retrospective study enrolled 34 patients underwent posterior cable-dragged reduction/cantilever-beam internal fixation surgery...

Intraoperative salvaged blood is used to reduce allogeneic blood transfusion in orthopedic surgery patients. However, salvaged blood reinfusion may lead to immune reactions. Salvaged and venous blood from 20 patients undergoing hip arthroplasty was processed. The salvaged samples were mixed with patients' venous blood and incubated in absence or presence of lipopolysaccharide. SAMPLES: Venous: venous patient blood (n=20). Native: mixed salvaged native blood (n=20). Filtered: mixed salvaged leukocyte filtered blood (n=20)...

BACKGROUND: The use of leeches can effectively increase the salvage rate of flap congestion. However, the first reaction from patients and carers in using leeches in clinical fields is strong aversion. This can be due to the fact that development of our culture from agriculture to industrial society, coming across leeches became fairly rare. Also because of the biological traits that leeches carry; staying attached to a leg or other body parts of the host, sucking blood, and leaving wounds...

INTRODUCTION: Uncontrolled haemorrhage is the leading cause of death on the battlefield, and two-thirds of these deaths result from non-compressible haemorrhage. Blood salvage and autotransfusion represent an alternative to conventional blood transfusion techniques for austere environments, potentially providing blood to the casualty at point of injury. The aim of this paper is to describe the design, development and initial proof-of-concept testing of a portable blood salvage and autotransfusion technology to enhance survivability of personnel requiring major medical interventions in austere or military environments...

Hypoxanthine catabolism in vivo is potentially dangerous as it fuels production of urate and, most importantly, hydrogen peroxide. However, it is unclear whether accumulation of intracellular and supernatant hypoxanthine in stored RBC units is clinically relevant for transfused recipients. Leukoreduced RBCs from G6PD-normal or -deficient human volunteers were stored in AS-3 under normoxic, hyperoxic, or hypoxic conditions (with SO2 ranging from <3 to >95%). RBCs from healthy human volunteers were also collected at sea level or after 1-7 days at high altitude (>5000m)...

We compared post-relapse overall survival (OS) after autologous-allogenenic (auto/allo) versus tandem autologous (auto/auto) hematopoietic cell transplantation (HCT) in multiple myeloma (MM). Post-relapse survival of patients receiving an auto/auto or auto/allo HCT for MM and prospectively reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 2000 and 2010 were analyzed. 404 patients (72.4%) relapsed in the auto/auto group and 178 patients (67.4%) relapsed in the auto/allo group after a median follow up of 8...

Anemia is common in elective surgery and is an independent risk factor for morbidity and mortality. Historical management of anemia has focused on the use of allogeneic blood transfusion but this in itself is not without risk. It too has been independently associated with morbidity and mortality, let alone the costs and relative shortage of this resource. In recognition of this, patient blood management (PBM) shifts the focus from the product to the patient and views the patient's own blood as a resource that should be conserved and managed appropriately as a standard of care...

BACKGROUND: Autologous blood transfusion, commonly referred to as cell saver, is frequently used in spinal fusion to salvage red blood cells because of the risk of significant intraoperative blood loss. This case report describes a case of acute kidney injury (AKI) secondary to cell saver use. Our objective is to increase the knowledge about the process of red blood cell salvage and this exceedingly rare complication. METHODS: Chart and renal biopsy results for a single case were reviewed and reported in this retrospective study...

BACKGROUND & AIMS: Prevention of catheter related blood stream infections (CRBSI) and salvage of infected central venous catheters (CVC) are vital to maintaining long term venous access in patients needing home parenteral nutrition (HPN). It remains unclear as to whether patients are best trained for catheter care at home or in hospital or whether CRBSIs are lower if the patient self-cares for the CVC. Furthermore, there is minimal data on the longer term outcome following salvage of infected catheter and limited consensus on agreed protocols for catheter salvage...

BACKGROUND: Standard treatment for clinical N2-locally advanced lung cancer is definitive chemoradiotherapy (CRT). For local recurrence or residual tumor after definitive CRT, salvage surgery may have effective treatment option with relatively high operative risk. OBJECTIVE: To examine the prognosis and risk of salvage surgery. METHOD: In 2001 to 2016, postoperative complications, overall survival and relapse free survival rate were examined in 17 patients who underwent salvage surgery after definitive CRT for clinical N2 or more primary lung cancer...

Donor-lymphocyte infusion (DLI) for relapse following haploidentical hematopoietic cell transplantation (haploHCT) with post-transplant cyclophosphamide (PTCy) has been described in recipients of bone marrow grafts, but not recipients of G-CSF mobilized peripheral blood (PB) grafts. We retrospectively identified patients who underwent DLI following PB-haploHCT with PTCy for relapse, or loss of chimerism (LOC). Twelve patients (57%) received DLI for hematologic relapse/persistent disease, seven (33%) for extramedullary relapse and two (10%) for LOC...

Brain injuries affect a large patient population with major physical and emotional suffering for patients and their relatives; at a significant cost to the society. Effective diagnostic and therapeutic options available for brain injuries are limited by the complex brain injury pathology involving blood-brain barrier (BBB). Brain injuries, including ischemic stroke and brain trauma, initiate BBB opening for a short period of time, which is followed by a second reopening for an extended time. The leaky BBB and/or the alterations in the receptor expression on BBB may provide opportunities for therapeutic delivery via nanoparticles (NPs)...

Adipose-derived mesenchymal stem cells (ASCs) have been shown to produce vascular endothelial growth factor (VEGF) and can increase perfusion in patients with critical limb ischemia. We will show that this concept can be applied to augment blood flow in zones of flap ischemia. We presented a case study of a 26-year-old man with a complex hand injury covered by a reverse radial perforator fasciocutaneous flap, which developed ischemic necrosis and was treated by debridement, transplantation of ASCs to enhance vascular support, and saline dressings...

Intra-operative blood cell salvage (IOCS) is mainly avoided in onco surgery due to the suspicion that it could increase metastasis' risk. We simulated IOCS followed by leucodepletion: HCT116 (human colorectal cancer) cells were inoculated into packed red blood cells units, and their distribution was evaluated, step-by-step, by flow cytometry and immunohistochemistry. Most of HCT116 cells were lost during washing, and almost completely removed after filtration. IOCS plus leucodepletion could be of great advantage for oncological patients, where allogenic blood transfusion could influence tumour progression...

OBJECTIVE: Early allograft dysfunction may be caused by several technical factors including vascular complications such as thrombosis, kinking, or extrinsic compression. Renal allograft compartment syndrome (RACS) is an unrecognized cause of early allograft dysfunction. This complication is characterized by increased pressure of the iliac fossa that reduces the blood supply to the graft with a potentially devastating consequence. The main objective when recognizing this condition is to create a tension-free muscle closure...

OBJECTIVES: Budding uninhibited by benzimidazole-related 1 (BubR1), a cell cycle-related protein, is an essential component of the spindle checkpoint that regulates cell division. Mice in which BubR1 expression is reduced to 10% of the normal level display the phenotypic features of progeria. However, the role of BubR1 in vascular diseases and angiogenesis remains unknown. To investigate the influence of BubR1 on angiogenesis, we generated a low-null-BubR1-expressing (BubR1(L/-)) mouse strain with reduced BubR1 expression as low as 15% of the normal level without any abnormalities in appearance...

Whilst autologous stem cell transplantation (auto-SCT) is considered standard of care for relapsed/refractory classical Hodgkin lymphoma, the role of auto-SCT in nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is not well defined due to limited data. We report the first study on auto-SCT for NLPHL with a larger cohort. Eligible for this retrospective registry study were patients reported to the EBMT between 2003 and 2013, aged 18 or older with relapsed/refractory NLPHL who underwent first auto-SCT with disease chemosensitive to salvage therapy...
