She was started on methotrexate (MTX) in X-1. She developed a cough, and chest computed tomography showed abnormalities. In X, MTX was discontinued, but the cough persisted. A lung biopsy revealed a diagnosis of nodular sclerosis classic Hodgkin lymphoma (CHL-NS). She was considered to have "other iatrogenic immunodeficiency-associated lymphoproli...

We report on 24 patients with recurrent AVM-associated GI bleeding who met criteria for and received thalidomide therapy, of which 17 had sufficient follow-up to be ultimately included for final analysis. We found the risk of rebleeding was significantly reduced in those on thalidomide therapy versus off (hazard ratio = 0.23, p = 0.022). The median number of GI bleeds per year was reduced from 4.6 to 0.4 (p = 0.0008) and the PRBC requirement was lower (36.1 vs. 0.9 units per year, p = 0.004) in those on thalidomide therapy. The adverse event rate with thalidomide was 59%, with symptoms resolution in most following dose red...

In this study, we investigated the effects of nitric oxide (NO) added to the sweep gas of an extracorporeal circuit in a neonatal ovine model. Eight lambs (age 9.6 ± 1.9 days) were cannulated via the neck vessels and maintained on a pumpless arteriovenous extracorporeal membrane oxygenation circuit with blood flow restricted to 100 ml/min for 72 hours. All animals were heparinized, and a subset (n = 4) also received NO in the sweep gas at a concentration of 200 ppm. We observed no adverse effects from NO administration, and methemoglobin levels remained unchanged. Platelet counts signific...

Ventricular assist devices (VADs) are an increasingly common therapy for end-stage heart failure across all ages as a bridge to recovery or transplant and more recently as destination therapy. With increasing experience and difficulties with establishing therapeutic heparin levels, we have begun to explore the effectiveness of direct thrombin inhibitors in this patient population. This is a retrospective review of all long-term VAD patients, both adult and pediatric, who were anticoagulated with bivalirudin between January 2009 and January 2016. The starting dose was 0.3 mg/kg/hr, and dose was titrated for a goal pa...

Nicotinamide Inhibits Glycolysis of HL-60 Cells by Modulating Sirtuin 1 (SIRT1)/Peroxisome Proliferator-Activated Receptor γ Coactivator 1α (PGC-1α)/Hypoxia-Inducible Factor-2α (HIF2α) Signaling Pathway. Med Sci Monit. 2020 May 29;26:e920810 Authors: Liu M, Zhou P, Li J, Jiang Y Abstract BACKGROUND Nicotinamide can affect differentiation and proliferation of leukemia cells. This research aimed to explore the regulatory effect of nicotinamide on glycolysis metabolism of leukemia cells and to clarify the associated mechanisms. MATERIAL AND METHODS HL-60 cells were treated wi...

Authors: Pablo A, Breaud AR, Clarke W Abstract Bone marrow transplantation is used to treat particular types of cancers such as lymphoma, leukemia, and multiple myeloma. Appropriate dosing of busulfan during the preparative phase is critical for a successful allograft; if blood concentrations get too high significant liver toxicity can occur, if blood concentrations are too low, then graft-versus-host disease (GVHD) can develop. Busulfan monitoring in blood allows hospitals with the opportunity to provide individualized medicine to patients and improve overall patient outcome. Liquid Chromatography-Tandem Mass Spec...
