In this week's episode we'll learn about how by combining PET response with circulating tumor DNA, or ctDNA, in newly treated patients with follicular lymphoma, investigators identify those patients likely to progress within 24 months of initial treatment, also known as POD24. After that: Immune hotspots in aplastic anemia. These newly identified hotspots potentially represent sites in the bone marrow where the active immune response takes place, driving the destruction of hematopoietic stem and progenitor cells. Finally, allogeneic transplantation for Hodgkin lymphoma in the checkpoint inhibitor era. In a large, retrospective study, patients with prior checkpoint inhibitor exposure had remarkable outcomes, particularly when post-transplant cyclophosphamide was used.

In this week's episode, we’ll learn more about how exogenous CD19 stimulation affects CAR T-cell persistence in B-cell acute lymphoblastic leukemia treated with CD19 CAR T-cell therapy; new algorithms that incorporate sequential rapid immune-assays, intended to improve diagnosis of heparin-induced thrombocytopenia, and resource-adaptive survival prediction models to help guide management of patients with chronic myelomonocytic leukemia.

In this episode, Associate Blood editor Dr. Selina Luger leads a discussion with Drs. Courtney DiNardo, Eunice Wang, Andrew Wei and Gail Roboz about the advances in treatment options for Acute Myeloid Leukemia (AML).

In this week's episode, we’ll learn more about the effects of daratumumab maintenance on minimal residual disease in patients with newly diagnosed, transplant-eligible multiple myeloma; the role of neutrophils in the pathophysiology of myeloproliferative neoplasms; and a genome-wide association study that identified novel genetic loci associated with the risk of heavy menstrual bleeding.

In this week's episode we'll learn more about enhanced transplant characteristics; targeting the JAK-STAT pathway with ruxolitinib in patients with adult-onset Still’s disease and macrophage activation syndrome; and a pair of trials demonstrating lack of benefit for the anti-CD47 monoclonal antibody magrolimab in newly diagnosed acute myeloid leukemia.

In this week's episode, we'll learn about a JAK inhibitor to prevent complications of CD19-directed CAR T-cell therapy. In a phase 2 study, itacitinib was well tolerated and demonstrated promising reductions in the incidence of cytokine release syndrome and neurotoxicity. After that: investigators report direct interactions between ChAdOx1 and platelets under arterial shear conditions. Investigators say it’s a novel biophysical mechanism that potentially contributes to post-vaccination arterial thrombosis. Finally, we explore lineage switch, an emerging form of acute leukemia relapse with dismal outcomes. It arises rapidly following antigen-targeted immunotherapy, highlighting the importance of advanced methods for detection and treatment.

In this week's episode we’ll learn more about the use of ruxolitinib plus dexamethasone to treat newly diagnosed patients with adult hemophagocytic lymphohistiocytosis; lysine-specific demethylase-1 inhibitors as a potential new class of therapies for sickle cell disease and other beta-globinopathies; and insights into clinical characteristics of patients with von Willebrand factor levels that are lower than normal but higher than those typically used to diagnose von Willebrand disease.
