Cellular immune profiling after sequential clofarabine and lenalidomide for high risk myelodysplastic syndromes and acute myeloid leukemia.

Patients with high risk myelodysplastic syndromes (MDS) and acute myelogenous leukemia (AML) are commonly older with multiple co-morbidities, rendering them unsuitable for intensive induction chemotherapy or transplantation. We report preliminary cellular immune profiling of four cases receiving sequential clofarabine and lenalidomide for high risk MDS and AML in a phase I study. Our results highlight the potential of immune profiling for monitoring immune-modifying agents in high risk MDS and AML.

First case report of SAM(r) Junctional tourniquet use in Afghanistan to control inguinal hemorrhage on the battlefield.

Junctional hemorrhage, bleeding that occurs at the junction of the trunk and its appendages, is the most common preventable cause of death from compressible hemorrhage on the battlefield. As of January 2014, four types of junctional tourniquets have been developed and cleared by the U.S.

Bone marrow mesenchymal stromal cells to treat tissue damage in allogeneic stem cell transplant recipients: correlation of biological markers with clinical responses.

Bone marrow mesenchymal stromal cells (BMSCs) have been used to treat acute graft-versus-host disease (GVHD) and other complications following allogeneic hematopoietic stem cell transplantation (SCT). We conducted a phase I trial using third party, early passage BMSCs for patients with steroid-refractory GVHD, tissue injury, or marrow failure following SCT to investigate safety and efficacy. To identify mechanisms of BMSC immunomodulation and tissue repair, patients were serially monitored for plasma GVHD biomarkers, cytokines, and lymphocyte phenotype.

Repair of impaired pulmonary function is possible in very-long-term allogeneic stem cell transplantation survivors.

Both early- and late-onset noninfectious pulmonary injury are important contributors to the nonrelapse mortality seen after allogeneic stem cell transplantation (allo-SCT), particularly in subjects conditioned with high-dose total body irradiation (TBI). To characterize the kinetics of recovery from pulmonary injury in long-term survivors, we collected data on 138 subjects who survived > 3 years (median survival, 10.2 years) after predominantly TBI-based allo-SCT from their HLA-matched siblings.

Male survivors of allogeneic hematopoietic stem cell transplantation have a long term persisting risk of cardiovascular events.

Long-term survivors of allogeneic stem cell transplantation (SCT) have increased risk of cardiovascular disease. We retrospectively studied cardiovascular risk factors (CVRFs) in 109 SCT survivors (62 males, 47 females; median age 34 years) five years or more after bone marrow (15) or T cell-depleted peripheral blood (94) SCT for CML (56), acute leukemia (29), MDS (13), and others (11). One death and two cardiovascular events were reported.

Radiation exposure from diagnostic procedures following allogeneic stem cell transplantation--how much is acceptable?

Background: Frequent diagnostic radiology procedures in allogeneic stem cell transplantation (SCT) recipients raise concern about the potential harm from incidental radiation.

Objectives: To determine the cumulative radiation dose from diagnostic studies in allogeneic SCT and its impact on clinical outcome.

Patients And Methods: This retrospective cohort study was conducted to determine the cumulative radiation dose from diagnostic studies following SCT.
