Next, we review results of a randomized phase 3 trial of enasidenib versus conventional treatment in late-stage mutant-IDH2 relapsed or refractory AML. Although the primary endpoint of ove...

In this episode, Associate Editor, Dr. Robert Zeiser and Dr. Yi-Bin Chen discuss the series on How I Manage High-Risk Patients Following Allogeneic Hematopoietic Cell Transplantation.

In this week’s episode we’ll discuss whether pregnancy increases the risk of bleeding in women with immune thrombocytopenia, compare the outcomes of allogeneic stem cell transplantation versus conservative management in adults with inborn errors of immunity, and learn more about the long-term health outcomes and late mortality in childhood AML survivors.

In this week’s episode, we'll discuss involvement of IL-13 and IL-4 signaling in fibrotic progression of myelofibrosis; next, we review results on a novel agent using vWF-dependent mechanisms to lyse pathological thrombi in acute ischemic stroke. Finally, we’ll shed new light on findings that implicate the GARP-TGF-beta-1 pathway in the loss of natural killer cell cytotoxicity in relapsed AML.

In this week’s episode, research shows that in patients with myelodysplastic syndromes, or MDS, the frequency of pathogenic or likely pathogenic germline variants is relatively high across all age groups, not just younger patients. Based on these results, it may be time to expand genetic testing to all patients.  Next, we'll review primary results of a prospective, multicenter study of children wi...
