OBJECTIVE To test the hypothesis that the mortality rate of acutely ill patients admitted to a medical ward or medical ICU is higher for those patients who present with hypomagnesemia than for those patients who do not present with hypomagnesemia. DESIGN Prospective, observational study. SETTING Emergency Department admissions to the medical ward and(More)
Elevated circulating endothelial cell (CEC) and circulating endothelial progenitor cell (CEPC) counts may indicate vascular damage and disease status, but data on these cell populations in patients with severe sepsis are limited. This study compared CEC and CEPC counts in patients with and without severe sepsis following intensive care unit (ICU) admission.(More)
So that changes in production and binding of tumor necrosis factor-alpha during postpneumonectomy lung growth could be determined, rats underwent left lung resection and were killed 3, 7, or 14 days later, 1 hour after the injection of 3H-thymidine. Serum was collected, and the lungs were lavaged and perfused in vitro. Lung volumes were measured. Lungs were(More)
To evaluate the mechanisms involved in the regulation of fibroblast function during the repair of fibrotic lung injury, we isolated lung fibroblasts from adult male Fischer-344 rats before the induction of severe unilateral paraquat lung injury, as well as 1 and 14 days later. Fibroblasts were utilized at an early generation time to avoid senescence. In(More)
We evaluated the effect of dexamethasone on the synthesis of fibronectin by rat lung fibroblasts. A dose dependent inhibition was observed in fibroblasts isolated from normal lungs and in fibroblasts isolated early (4 days) and late (14 days) after the administration of endobronchial paraquat, and was more pronounced in fibroblasts exposed to dexamethasone(More)
A patient was administered drotrecogin alfa (activated) in addition to the standard of care for presumed severe sepsis and circulatory shock. Heparin-induced thrombocytopenia (HIT) and hepatic and splenic thromboses complicated her clinical course. Because drotrecogin alfa (activated) treatment is associated with improvement in thrombotic manifestations and(More)
