Lobectomy for Lung Cancer at Veterans Administration Medical Center Versus Academic Medical Center.

Background: Hospital and surgeon volume each have an association with postoperative outcomes. The volume of lung cancer surgery at our Veterans Administration Medical Center (VAMC) is lower than at our academic medical center (AMC). We compared the outcomes after lobectomy at VAMC versus AMC to identify specific areas of clinical care requiring quality improvement.

Divergent roles of murine neutrophil chemokines in hemorrhage induced priming for acute lung injury.

Neutrophil associated lung injury is identified with a variety of local and systemic priming insults. In vitro studies have shown that TNF-alpha mediated suppression of neutrophil apoptosis is due to the secretion of interleukin-8 (IL-8), a human chemokine shown to alter neutrophil chemotaxis. Our initial in vitro antibody neutralization studies with neutrophil chemotactic proteins, keratinocyte-derived chemokine (KC) and macrophage inflammatory protein-2alpha (MIP-2alpha), mouse IL-8 homologues, indicate that MIP-2alpha but not KC appears to mediate TNF-alpha suppression of mouse neutrophil apoptosis.
