Clinicopathologic and Molecular Characterization of NUP98-Rearranged Acute Leukemias.

Introduction: NUP98 rearrangements are rare in acute leukemias and portend a poor prognosis.

Methods: This study explored clinicopathologic and molecular features of five patients with NUP98 rearranged (NUP98-r) acute leukemias, including three females and two males with a median age of 34 years.

Results: NUP98 fusion partners were associated with distinctive leukemia characteristics and biology.

Genomic heterogeneity within B/T mixed phenotype acute leukemia in a context of an immunophenotype.

B/T mixed phenotype acute leukemia (MPAL) is a rare aggressive leukemia. Three cases of B/T MPAL were identified with comprehensive immunophenotypic, cytogenetic, and molecular studies. T-lineage predominant B/T MPAL shares a genetic signature with T-ALL whereas B/T lineage co-dominant B/T MPAL lacks such a T-ALL signature All three patients were treated with lineage-matched-ALL therapy and alive at the last follow-up.

Association between event-free survival and overall survival in early-stage triple-negative breast cancer.

This study evaluated event-free survival (EFS) as a surrogate outcome for overall survival (OS) in neoadjuvant therapy for early-stage triple-negative breast cancer (eTNBC). Meta-regression analyses based on a targeted literature review were used to evaluate the individual- and trial-level associations between EFS and OS. In the individual-level analyses, 3-year EFS was a significant predictor of 5-year OS (p < 0.

How important is the spatial movement of people in attempts to eliminate the transmission of human helminth infections by mass drug administration?

Human mobility contributes to the spatial dynamics of many infectious diseases, and understanding these dynamics helps us to determine the most effective ways to intervene and plan surveillance. In this paper, we describe a novel transmission model for the spatial dynamics of hookworm, a parasitic worm which is a common infection across sub-Saharan Africa, East Asia and the Pacific islands. We fit our model, with and without mobility, to data obtained from a sub-county in Kenya, and validate the model's predictions against the decline in prevalence observed over the course of a clustered randomized control trial evaluating methods of administering mass chemotherapy.

After Bone Marrow Transplantation, the Cell-Intrinsic Th2 Pathway Promotes Recipient T Lymphocyte Survival and Regulates Graft-versus-Host Disease.

Recipient T cells can aggravate or regulate lethal and devastating graft-versus-host disease (GVHD) after bone marrow transplantation (BMT). In this context, we have shown before that intestinal immune conditioning with helminths is associated with survival of recipient T cells and Th2 pathway-dependent regulation of GVHD. We investigated the mechanism of survival of recipient T cells and their contribution to GVHD pathogenesis in this helminth infection and BMT model after myeloablative preparation with total body irradiation in mice.
