Lactoferrin (LF) is a pleiotropic glycoprotein that is found in bodily secretions and is postulated to enhance the gastrointestinal barrier and promote mucosal immunity. Thus, the ability of talactoferrin, an oral recombinant form of human LF, to limit gut injury and the production of biologically active gut-derived products was tested using a rat model of trauma-hemorrhagic shock (T/HS). ⋯ These results provide a proof of principle that prophylactic dosing of oral talactoferrin can potentially protect the gut in a T/HS model and limit the production of biologically active factors in rat gastrointestinal tissue subjected to ischemia-reperfusion-type injuries.

Comparative Study
Retrograde flush is more protective than heparin in the uncontrolled donation after circulatory death lung donor.
Formation of microthrombi after circulatory arrest is a concern for the development of reperfusion injury in lung recipients from donation after circulatory death (DCD) donors. In this isolated lung reperfusion study, we compared the effect of postmortem heparinization with preharvest retrograde pulmonary flush or both. ⋯ This study suggests that preharvest retrograde flush is more protective than postmortem heparinization to prevent reperfusion injury in lungs recovered from donation after circulatory death donors.

Large extracompartmental limb soft-tissue sarcoma with juxta-articular bone involvement poses major challenges in disease management. Radical resection of sarcoma frequently requires concomitant bone resection and reconstruction. We describe the clinical outcomes of endoprosthetic reconstruction and the complications associated with this procedure. ⋯ Endoprosthetic reconstruction could yield satisfactory results as a wide excision and limb salvage therapeutic strategy for patients with large extracompartmental soft-tissue sarcomas with juxta-articular bone involvement. Acceptable complications occurred in the present report.

Laparoscopic common bile duct exploration (LCBDE) has already been established for the treatment of patients with common bile duct stones (CBDS) in elective situations. However, the effect of emergent LCBDE on those patients with nonsevere acute cholangitis has not been assessed. The aim of this study was to evaluate the effect of emergent LCBDE on patients with nonsevere acute cholangitis complicated with CBDS. ⋯ Our data indicated that emergent LCBDE is as safe and effective as elective LCBDE for the treatment of patients with nonsevere acute cholangitis complicated with CBDS.

Evaluating the cervical spine in the obtunded trauma patient is a subject fraught with controversy. Some authors assert that a negative computed tomography (CT) scan is sufficient. Others argue that CT alone misses occult unstable injuries, and magnetic resonance imaging (MRI) will alter treatment. This study examines the data in an urban, county trauma center to determine if a negative cervical spine CT scan is sufficient to clear the obtunded trauma patient. ⋯ In the obtunded trauma patient with a negative cervical spine CT, obtaining an MRI does not appear to significantly alter management, and no unstable injuries were missed on CT scan. This should be taken into consideration given the current efforts at cost-containment in the health care system. It is one of the larger studies published to date.
