Despite significant advances in the treatment of multiple myeloma (MM), most patients succumb to disease progression. One of the major immunosuppressive mechanisms that is believed to play a role in myeloma progression, is the expansion of regulatory T-cells (Tregs). In this study, we demonstrate that myeloma cells drive Treg expansion and activation by secreting type-1 interferon (IFN). Blocking IFNAR1 (interferon alpha and beta receptor 1) on Tregs significantly decreases both, myeloma-associated Treg immunosuppressive function and myeloma progression...

BACKGROUND: Interest in the therapeutic potential of bone marrow aspirate concentrate (BMAC) has grown exponentially. However, comparisons among studies and their processing methods are challenging because of inconsistent reporting of protocols, as well as poor characterization of the composition of the initial bone marrow aspirate and of the final products delivered. The purpose of this study was to perform a systematic review of the literature to evaluate the level of reporting related to the protocols used for BMAC preparation and the composition of BMAC utilized in the treatment of musculoskeletal diseases in published clinical studies...

BACKGROUND: Some wild animals have been recognized as potential reservoirs of Leishmania infantum infection (e.g. carnivores, lagomorphs, rodents, etc.). Leishmania infantum was also identified infecting humans and lagomorphs (i.e. hares and rabbits) over the period of 2009-2016, with the latter acting as the main reservoirs involved in the human leishmaniosis outbreak in Madrid. RESULTS: Two cases of clinical leishmaniosis are reported in orangutans (Pongo pygmaeus pygmaeus) housed at two different centres in Madrid...

Response criteria in acute myeloid leukemia (AML) has recently been re-established, with morphologic examination utilized to determine whether patients have achieved complete remission (CR). Approximately half of the adult patients who entered CR will relapse within 12 months due to the outgrowth of residual AML cells in the bone marrow. The quantitation of these remaining leukemia cells, known as minimal or measurable residual disease (MRD), can be a robust biomarker for the prediction of these relapses. Moreover, retrospective analysis of several studies has shown that the presence of MRD in the bone marrow of AML patients correlates with poor survival...

BACKGROUND: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. METHODS: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis...

Background: Human parvovirus B19 (HPV-B19) is the etiologic agent of erythema infectiosum, of transient aplastic crises in individuals with underlying chronic hemolytic disorders, and of chronic pure red cell aplasia in immunocompromised individuals. Case report: We describe a 14-year-old girl with long-standing Evans syndrome, who presented with severe anemia, reticulocytopenia and thrombocytopenia. A bone marrow aspirate revealed severe erythroid hypoplasia along with the presence of giant pronormoblasts, while serological studies and real-time PCR of whole blood were positive for acute parvovirus B19 infection...

BACKGROUND: Chronic lymphocytic leukemia and chronic myeloid leukemia are the most common types of adult leukemia. However, it is rare for the same patient to suffer from both. Richter's transformation to diffuse large B-cell lymphoma is frequently observed in chronic lymphocytic leukemia. Purine analog therapy and the presence of trisomy 12, and CCND1 gene rearrangement have been linked to increased risk of Richter's transformation. The coexistence of chronic myeloid leukemia and diffuse large B-cell lymphoma in the same patient is extremely rare, with only nine reported cases...

We report on three cases of pediatric acute lymphoblastic leukemia presenting with bone pain and arthralgia as initial symptoms. At the first visit, their primary signs were recurrent bone pain and arthralgia, without significant peripheral blood abnormalities. It took 2-4 months to confirm the diagnosis from the onset of arthralgia due to this atypical presentation of the disease. Definitive diagnosis was obtained by bone marrow examination, and in all cases, complete remission was achieved by chemotherapy...

Articular defects are a major problem with few effective treatment options. Osteochondral allograft (OCA) transplantation can be an effective treatment; however, lack of OCA bone integration can cause failure. This controlled laboratory study was designed to compare clinically applicable methods for marrow element removal and enhanced delivery of bone marrow aspirate concentrate (BMC) to OCA bone. We hypothesized that compressed carbon dioxide (CO2 ) treatment of OCA bone would result in significantly better marrow element removal, significantly more retention and distribution of viable osteoprogenitor cells, and significantly higher osteoinductive protein elution from OCAs compared with other preimplantation treatments...

RATIONALE: Both acute lymphoblastic leukemia (ALL) and Ewing sarcoma (ES) are small round cell tumors, and it is difficult to differential diagnose them because of overlapping clinical, radiographic, histologic, and immunophenotypic features. PATIENT'S CONCERNS: A 5-year-old boy was admitted to our hospital because of pains in his left leg without obvious inducement and lameness worsening with walking over a two 2-month period. DIAGNOSES: Based on the comprehensive analysis of radiography, magnetic resonance imaging (MRI), pathology biopsy and immunohistochemistry, the lesion was confirmed to be ES...

OBJECTIVE: Ethnic minorities (nonwhites) with critical limb ischemia (CLI) have historically performed worse compared with whites with regard to major amputation risk reduction and amputation-free survival (AFS) after peripheral vascular intervention. This post hoc analysis was completed to determine whether this precedent also extended to treatment of CLI without a suitable revascularization option with intramuscular injections of concentrated bone marrow aspirate (cBMA). METHODS: The treatment arm of the randomized, double-blind, multicenter MarrowStim PAD Kit for the Treatment of Critical Limb Ischemia in Subjects with Severe Peripheral Arterial Disease (MOBILE) trial was stratified by ethnicity and evaluated for demographics, comorbidities, and outcomes...

BACKGROUND: Chronic myelogenous leukemia (CML) is a myeloproliferative disorder characterized by the Philadelphia (Ph) chromosome generated by the reciprocal translocation t(9,22)(q34;q11). The natural progression of the disease follows a biphasic or triphasic course. Most cases of CML are diagnosed in the chronic phase. Extramedullary blast crisis rarely occurs during the course of CML, and is extremely rare as the initial presentation of CML. CASE PRESENTATION: Here, we report the case of a 32-year-old female with enlarged neck lymph nodes and fatigue...

Introduction The morbidity and significant health economic impact associated with the chondral lesion has led to a large number of strategies for therapeutic neochondrogenesis. The challenge has been to develop techniques that are cost effective single-stage procedures with minimal surgical trauma that have undergone rigorous preclinical scrutiny and robust reproducible assessment of effectiveness. A biological repair requires the generation of a cellular and matrix composite with appropriate signalling for chondrogenic differentiation...

Anti-CD22 moxetumomab pasudotox achieved 46% complete remissions (CRs) in previously reported phase I testing in relapsed/refractory hairy cell leukemia (HCL; n=28). The importance of minimal residual disease (MRD) after CR in HCL is unknown. A 21-patient extension cohort received 50 µg/kg every other day for 3 doses in 4-week cycles. These patients plus 12 previously reported at this upper dose level received 143 cycles without dose-limiting toxicity. The combined 33-patient cohort achieved 64% CR and 88% overall response rates, with median CR duration of 42...

BACKGROUND: Intraosseous (IO) vascular access is increasingly used as an emergency tool for achieving access to the systemic circulation in critically ill patients. The role of IO transfusion of blood in Damage Control Resuscitation is however questionable due to possible inadequate flow rate and hemolysis. Some experts claim that IO transfusion is contraindicated. In this study we have challenged this statement by looking at flow rates of autologous fresh whole blood reinfusion and hemolysis using two of the commonly used FDA-approved and CE-marked sternal needles...
