Endothelial progenitor cells and BMSCs were isolated and purified from the peripheral blood and bone marrow, respectively, of New Zealand rabbits. The third passage of BMSCs was cultured alone or with EPCs. Cells were characterized using specific markers and then seeded on partially deproteinized biologic bones from pigs as a scaffold. The engineered bones were used to repair bone defects in rabbits. Hematoxylin and eosin and Masson staining were performed to examine vascularization and osteogenesis in the engineered bone. The cocultured EPCs and BMSCs grew well on the surface of the scaffold. Compared with monocultured BMSCs, cocultured EPCs and BMSCs promoted the formation of blood vessels and bone on the scaffold, in addition to accelerating the repair of bone defects. The collagen content was significantly increased in the scaffold with cocultured EPCs and BMSCs, compared with the scaffold seeded with mono-cultured BMSCs. Tissue-engineered bones seeded with cocultured EPCs and BMSCs may be used effectively for the repair of bone defects. Tissue-engineered bones seeded with cocultured EPCs and BMSCs may be used effectively for the repair of bone defects. Carbon monoxide is a gas produced by the combustion of hydrocarbon products that binds to heme molecules, 240 times more than oxygen, producing carboxyhemoglobin (COHb). As a result of its high affinity, there is shift of the oxyhemoglobin dissociation curve, compromising oxygen transport and delivery to tissues. Our study aim was to evaluate COHb elevation on admission as a predictor of worse outcomes in burn patients. This is a 10-year retrospective review of the American Burn Association Burn Registry from 2002 to 2011. We stratified the patients in
