Blood Podcast

In this week’s episode, we will learn about vasomotor hyper-responsiveness in sickle cell disease, examine the role of neutrophil extracellular traps in the pathophysiology of immunothrombosis in COVID-19-associated acute respiratory distress syndrome, and discuss a large series evaluating allogeneic hemopoietic cell transplantation in chronic granulomatous disease.

In this week’s episode, we will review a study that identifies a new modular organization of erythropoiesis and offers a novel strategy to overcome chronic anemias, summarize a study that used data from two large phase three trials to examine the risk of thrombosis in patients with newly diagnosed multiple myeloma, and review the first report of autosomal recessive germline TET2 deficiency, which results in immunodeficiency, autoimmune lymphoproliferation, and lymphoma.

In this week’s episode we will review a study exploring recurrent somatic deletions at chromosome 13q12.2 in acute lymphoblastic leukemia leading to upregulation of FLT3, examine how matriptase-2 plays a key role in suppressing hepatic hepcidin expression, and learn about the addition of daratumumab to lenalidomide, bortezomib, and dexamethasone as a quadruple therapy for transplant eligible patients with newly diagnosed multiple myeloma.

In this week’s episode we will review a study exploring the use of demethylating agents in patients with adult T-cell leukemia-lymphoma, learn more about hematopoietic stem cell formation, and examine treatment timing and prognosis in newly diagnosed patients with acute myeloid leukemia.

In this week’s episode we will review a study exploring the use of a novel hemophilia A mouse model to examine emicizumab function in vivo, a new approach to fighting the cytokine storm of HLH with a combination of glucocorticoids and ruxolitinib, and a timely Letter to Blood about red cell-bound antibodies and transfusion requirements in hospitalized patients with COVID-19.

In this week's episode we will review a study that demonstrates how the impaired hematopoietic stem cells (HSCs) observed in β-thalassemia can be rescued by administration of parathyroid hormone, learn more about genetic variants that can increase the risk of venous thromboembolism, and explore the identification of two DNA methylation subtypes of Waldenström’s macroglobulinemia.

In this episode we will review a study identifying cyclin-dependent kinase 6 (or CDK6) as a therapeutic target of NUP98-driven acute myeloid leukemia (or AML), learn more about the largest clinical dataset on cold agglutinin disease, and examine the effects of COVID-19 on coagulation parameters as well as bleeding and thrombosis in hospitalized patients.

In this episode we’ll review the risk of bleeding after initiating treatment for acquired hemophilia A, examine the functional effect of antibodies leading to immune TTP and how this can be used as a biomarker, and finally, a blast from the past – we will discuss a study that explores the intriguing possibility that a core component driving globin gene expression became active long ago.

This week we’ll review data that suggests the pro-inflammatory environment associated with aging alters hematopoietic stem cell function by inducing IL27 receptor alpha expression, examine a study attempting to optimize antiplatelet therapy in essential thrombocythemia, and learn more about a study by investigators who have proposed that myelodysplastic syndrome patients with mutations in SF3B1 identify a new subtype of that disease.

This week we will explore the impact of calreticulin (or CALR) haploinsufficiency on hematopoietic stem cell activity in the context of myeloproliferative neoplasms, explore mechanisms of leukemogenesis related to the E2A-PBX1 fusion protein in childhood B-cell acute lymphoblastic leukemia, and learn about the connection between intestinal microbiota, their metabolite short chain fatty acids and chronic graft versus host disease after allogeneic stem cell transplantation.
