Blood salvage

Extranodal natural killer/T-cell lymphoma-associated hemophagocytic lymphohistiocytosis (ENKTCL-LAHS) is a rare disease with poor prognosis. Currently, there are no well-established treatments for LAHS. Almost 50% of patients experience relapsed or refractory disease to anti-hemophagocytic lymphohistiocytosis (HLH) treatment, and the regimen for salvage therapy is limited. We report a case of ENKTCL-LAHS that was successfully treated with a programmed cell death ligand 1 (PD-L1) antibody (sugemalimab) alone and provide a literature review on existing ENKTCL-LAHS treatment options...

BACKGROUND: Megaprostheses contain many more modular components than conventional total hip and knee arthroplasty, which may lead to higher serum levels of metal ions. The aim of this study was to determine serum concentrations of titanium, chromium, and cobalt ions in cancer patients after limb salvage surgery with a megaprosthesis. METHODS: A retrospective, descriptive cohort analysis consisting of patients who underwent cancer-related limb salvage surgery with a megaprosthesis at our hospital between 2010 and 2020 was conducted...

BACKGROUND: Postpartum anemia is a significant contributor to peripartum morbidity. The utilization of cell salvage in low risk cases and its impact on postpartum anemia has not been investigated. We therefore aimed to examine the impact of autologous blood transfusion/cell salvage in routine cesarean delivery on postoperative hematocrit and anemia. STUDY DESIGN AND METHODS: Retrospective cohort study from a perfusion database from a large academic center where cell salvage is performed at the discretion of the obstetrical team...

BACKGROUND: Approximately two-thirds of patients with relapsed or refractory large B-cell lymphoma (R/R LBCL) do not respond to or relapse after anti-CD19 chimeric antigen receptor T (CAR T)-cell therapy, leading to poor outcomes. Previous studies have suggested that intensified lymphodepletion and hematological stem cell infusion can promote adoptively transferred T-cell expansion, enhancing antitumor effects. Therefore, we conducted a phase I/II clinical trial in which CNCT19 (an anti-CD19 CAR T-cell) was administered after myeloablative high-dose chemotherapy and autologous stem cell transplantation (HDT/ASCT) in patients with R/R LBCL...

AIMS: The aim of this study was to investigate the safety and efficacy of 3D-printed modular prostheses in patients who underwent joint-sparing limb salvage surgery (JSLSS) for malignant femoral diaphyseal bone tumours. METHODS: We retrospectively reviewed 17 patients (13 males and four females) with femoral diaphyseal tumours who underwent JSLSS in our hospital. RESULTS: In all, 17 patients with locally aggressive bone tumours (Enneking stage IIB) located in the femoral shaft underwent JSLSS and reconstruction with 3D-printed modular prostheses between January 2020 and June 2022...

Objective: To analyze the efficacy and safety of the L-DEP regimen (asparaginase, liposome doxorubicin, etoposide and methylprednisolone) as a salvage therapy for the refractory primary hemophagocytic lymphohistocytosis triggered by Epstein-Barr virus infection (EBV-pHLH) in children. Methods: In this retrospective case study, clinical and laboratory data before and after L-DEP regimen of 4 children diagnosed with EBV-pHLH in Beijing Children's hospital between January 2016 and June 2022 were collected, and the efficacy and safety of L-DEP regimen for the treatment of EBV-pHLH were analyzed...

CAR T-cell therapy has transformed relapsed/refractory (r/r) B-cell precursor acute lymphoblastic leukaemia (B-ALL) management and outcomes, but following CAR T infusion, interventions are often needed. In a UK multicentre study, we retrospectively evaluated tisagenlecleucel outcomes in all eligible patients, analysing overall survival (OS) and event-free survival (EFS) with standard and stringent definitions, the latter including measurable residual disease (MRD) emergence and further anti-leukaemic therapy...

BACKGROUND: We report a case of isolated ductal origin of pulmonary artery (DOPA) diagnosed in an asymptomatic newborn. The primary aim of this case is to highlight the need to investigate for DOPA in patients diagnosed with an 'absent branch pulmonary artery'. CASE SUMMARY: Our patient was an asymptomatic newborn infant, with normal intracardiac anatomy. He was initially diagnosed post-natally with 'absent left pulmonary artery' (LPA), though the LPA was seen in antenatal scans...

INTRODUCTION: Stroke interventions that increase collateral flow have the potential to salvage penumbral tissue and increase the number of patients eligible for reperfusion therapy. We compared the efficacy of two different collateral therapeutics during transient middle cerebral artery occlusion (tMCAO) in normotensive and hypertensive rats. METHODS: The change in collateral and core perfusion was measured using dual laser Doppler in response to either a pressor agent (phenylephrine, 10 mg/kg iv or vehicle) or a collateral vasodilator (TM5441, 5 mg/kg iv or vehicle) given 30 min into tMCAO in male Wistar and spontaneously hypertensive rats (SHRs)...

Autologous blood transfusion can be achieved through different techniques, including by the patient donating blood before surgery (pre-deposit), collecting blood from the patient immediately before the operation and replacing the volume with colloids or plasma expanders (acute normovolemic hemodilution) or through the salvage of lost blood, during or immediately after surgery, and its retransfusion after washing (intraoperative or postoperative recovery). We will focus on the two methods used intraoperatively that are of fundamental importance in the management and conservation of the patient's own blood...

Cochlear implant surgery is the standard of care for severe sensorineural hearing loss. Infection followed by implant extrusion is an infrequent complication of this surgery. The ideal treatment is explantation of the implant. However, implant removal and reimplantation is a challenging surgery and may have poor speech reception outcomes. The cost of a new implant especially in developing countries is also a deterrent. Our study dwells on the feasibility of salvaging exposed cochlear implants by a combination of pericranial flaps followed by a scalp flap cover...

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) devices are well-established adjunctive treatment measures for patients with heart failure. ECMO can serve as a bridge to transplant in a chronic setting or as a salvage therapy for patients who are unable to be weaned from bypass following cardiac surgery. However, the role of ECMO as a bridge to definitive therapy in a setting of acute heart failure is less established. Similarly, the treatment of patients using combined ECMO and ECLS devices has been, at times, shown to show some benefit; however, these benefits have not been widely studied...

A 67-year-old man presented for urgent liver transplantation (LT). Screening revealed the rare combination of antiRhesus (D) and antiKidd Jk(a) antibodies, requiring antigen-negative red blood cells (RBC) for both phenotypes. This combination has not been reported during LT. Compatible RBCs were initially limited, requiring continued communication between the blood bank/blood supplier to obtain more, including frozen, units. Additional strategies included the use of cell salvage and intentional management of coagulopathy to limit bleeding and RBC requirement...

BACKGROUND: Chimeric antigen receptor (CAR) T cells targeting CD30 are safe and have promising activity when preceded by lymphodepleting chemotherapy. We aimed to determine the safety of anti-CD30 CAR T cells as consolidation after autologous haematopoietic stem-cell transplantation (HSCT) in patients with CD30+ lymphoma at high risk of relapse. METHODS: This phase 1 dose-escalation study was performed at two sites in the USA. Patients aged 3 years and older, with classical Hodgkin lymphoma or non-Hodgkin lymphoma with CD30+ disease documented by immunohistochemistry, and a Karnofsky performance score of more than 60% planned for autologous HSCT were eligible if they were considered high risk for relapse as defined by primary refractory disease or relapse within 12 months of initial therapy or extranodal involvement at the start of pre-transplantation salvage therapy...

Objective  Meningiomas are the most common extra-axial tumors of the central nervous system. Meningiomas are particularly problematic when they invade deep or vital structures, causing the tumors to be inoperable. Nonsurgical adjunctive or salvage treatments to shrink a meningioma with multiple recurrences, located in deep-seated area or surgically unfit area, remain underexplored. The authors report a rare case of a spontaneously necrotic meningioma (World Health Organization [WHO] grade I) in a patient with systemic lupus erythematosus on chronic methotrexate and hydroxychloroquine...

UNLABELLED: There is a problem of bacterial contamination of autologous blood despite long-term experience of intraoperative blood salvage and reinfusion. OBJECTIVE: To analyze safety of blood reinfusion with white blood cell filtration and X-ray irradiation for blood decontamination in neurosurgery. MATERIAL AND METHODS: The study included 57 patients with various neurosurgical diseases. We used intraoperative blood reinfusion in all patients considering high predictable risk of major blood loss due to neurosurgical diseases, features of neoplasm topography, anamnesis and examination data...

The neurovascular unit includes multiple different cell types, including neurons, astrocytes, endothelial cells and pericytes, which respond to insults on very different time or dose scales. We defined differential vulnerability among these cell types, using response to two different insults: oxygen-glucose deprivation and thrombin-mediated cytotoxicity. We found that neurons are most vulnerable, followed by endothelial cells, followed by astrocytes. After temporary focal cerebral ischemia in male rats, we found significantly more injured neurons, compared to astrocytes in the ischemic area, consistent with differential vulnerability in vivo...

PURPOSE: This study aims to introduce the Unilateral Biplanar Screw-Rod Fixation (UBSF) technique (A hybrid fixation technique: Two sets of atlantoaxial screws were placed on the same side), which serves as a salvage method for traditional posterior atlantoaxial fixation. To summarize the indications of this technique and to assess its safety, feasibility, and clinical effectiveness in the treatment of odontoid fractures. METHODS: Patients with odontoid fractures were enrolled according to special criteria...

BACKGROUND: Popliteal artery injury (PAI) is a challenging condition. Even with appropriate initial treatment and reconstruction of the associated injuries, extensive soft-tissue necrosis may occur, requiring lower leg amputation. There are no reports on the effectiveness of orthoplastic surgery in treating traumatic PAI. However, orthoplastic surgery is also considered very effective in PAI treatment, which requires delicate handling of soft-tissue and blood vessels. This study aimed to examine the treatment outcomes of traumatic PAI at a trauma center with the capacity for orthoplastic management...

BACKGROUND: Endoscopic therapy is the first-line treatment of choice for control of acute variceal bleeding (AVB). In high-risk patients with persistent AVB despite pharmacological treatment and endoscopic intervention, percutaneous transjugular intrahepatic portosystemic shunting (TIPS) provides a minimally invasive salvage method to reduce portal pressure and control bleeding. OBJECTIVES: To evaluate factors influencing in-hospital mortality after salvage TIPS (sTIPS) in patients with exsanguinating variceal bleeding despite medical treatment and endoscopic intervention...
