Journal ArticleDOI
Hypoxia limits antioxidant capacity in red blood cells by altering glycolytic pathway dominance
TL;DR: Hypoxia limits antioxidant capacity in red blood cells by altering glycolytic pathway dominance, and implicate hypoxemia in the pathobiology of erythrocyte‐based vascular signaling.
Journal ArticleDOI
Incidence of Platelet Dysfunction by Thromboelastography-Platelet Mapping in Children Supported with ECMO: A Pilot Retrospective Study.
Arun Saini,Mary E. Hartman,Brian F. Gage,Ahmed S. Said,Avihu Z. Gazit,Pirooz Eghtesady,Umar S. Boston,Philip C. Spinella +7 more
TL;DR: In this paper, a pilot study was conducted to determine the incidence and magnitude of platelet dysfunction according to thromboelastography (TEG®)-platelet mapping (PM) testing.
Journal ArticleDOI
Physiologic impact of circulating RBC microparticles upon blood-vascular interactions
TL;DR: RMPs are submicron particles released from RBCs, with demonstrated vasoactive properties that appear to disturb oxygen delivery homeostasis; this physiology has been proposed to contribute to the impaired oxygen deliveryHomeostasis that may be observed following transfusion.
Journal ArticleDOI
RBC Distribution Width: Biomarker for Red Cell Dysfunction and Critical Illness Outcome?
Ahmed S. Said,Philip C. Spinella,Mary E. Hartman,Katherine M. Steffen,Ronald Jackups,Richard Holubkov,Mike Wallendorf,Allan Doctor +7 more
TL;DR: It is suggested that RBC distribution width may be a biomarker for RBC injury that is of sufficient magnitude to influence critical illness outcome, possibly via oxygen delivery impairment.
Journal ArticleDOI
Is anticoagulation with bivalirudin comparable to heparin for pediatric extracorporeal life support? Results from a high-volume center.
Matthew R. Schill,Matthew T. Douds,Emily L. Burns,Michael A. Lahart,Ahmed S. Said,Aaron M. Abarbanell +5 more
TL;DR: While this is the largest reported series comparing children on ECLS anticoagulated with heparin versus bivalirudin, larger studies are needed to determine the optimal antICOagulation strategy for this diverse and complicated group of children.
