The prognosis of early gastric cancer (EGC) with signet ring cell histology is more favorable than other undifferentiated gastric adenocarcinomas. An accurate assessment of potential lymph node metastasis is important for the appropriate treatment of EGC with signet ring cell histology. Therefore, this study analyzed the predictive factors associated with lymph node metastasis in patients with this type of EGC. ⋯ The risk of lymph node metastasis of EGC with signet ring cell histology was high in those with tumor sizes ≥2 cm, submucosal tumors, and lymphovascular invasion. A minimally invasive treatment, such as endoscopic resection, might be possible in highly selective cases of EGC with signet ring cell histology with intramucosal invasion, tumor size <2 cm, and no lymphovascular invasion.

Management of organ donors in the intensive care unit is an emerging subject in critical care and transplantation. This study evaluates organ yield outcomes for a large number of patients managed by the Indiana Organ Procurement Organization. ⋯ Initial DMP met does not appear to be a significant prognostic factor for OTPD. Aggregate DMP is associated with transplantation rates for most organs, with analysis of individual parameters suggesting that appropriate management of oxygenation, volume status, and vasopressor use could lead to more organs procured per donor.

Hepatic ischemia-reperfusion injury has a significant impact on liver resection and transplantation. Many strategies have been developed to reduce the effects of ischemia-reperfusion injury, including pharmacologic and ischemic preconditioning; however, studies comparing these two methods are lacking. ⋯ Our results suggest an early protective effect of PharmPC (lower levels of C-reactive protein soon after ischemia). The protective effect observed after reperfusion was higher with PharmPC than with ischemic preconditioning. The simultaneous use of both methods could potentiate protection for ischemia-reperfusion.

There is debate in the trauma literature regarding the effect of prolonged prehospital transport on morbidity and mortality. This study analyzes the management of hepatic trauma patients requiring surgery and compares the outcomes of the group that was transferred to the University of New Mexico Hospital (UNMH) from outside institutions, to the directly admitted group. ⋯ There was no significant difference in liver injury grade, ISS, LOS, and mortality between TG and DAG. In the patient population of our study, transfer status did not affect outcome.

The early removal of central intravenous (IV) catheters, as a means of reducing the incidence of central line-associated blood stream infections (CLABSI), remains a major health care initiative. However, attaining IV access in the surgical intensive care unit (SICU) can be quite difficult. We report the success of a novel, resident-driven program for the placement of ultrasound-guided midline catheters in critically ill patients. ⋯ Ultrasound-guided midline catheters placed by the housestaff are a cost-effective alternative for patients in the SICU with difficult IV access. Successful placement can help facilitate early central line removal and thus may reduce CLABSI rates.
