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. Featured Articles: Outcomes of PLAT-02 and PLAT-03: evaluating CD19 CAR T-cell therapy and CD19-expressing T-APC support in pediatric B-ALL Sequential combinations of rapid immunoassays for prompt recognition of heparin-induced thrombocytopenia BLAST: a globally applicable and molecularly versatile survival model for chronic myelomonocytic leukemia
