The purpose of this study was to determine the effects of race, socioeconomic status, and demographic and clinical variables on the outcomes of gastrointestinal stromal tumors (GISTs). ⋯ Before 2000, African Americans were less likely to have surgery, and they demonstrated an overall increased mortality rate for GIST. Since 2000, African Americans have benefited from increased surgical resection rates, decreased perioperative mortality, and improved longterm survival. These changes have appeared to erase racial disparities in the treatment of GIST.

Randomized Controlled Trial Comparative Study
Randomized trial of emergency endoscopic sclerotherapy versus emergency portacaval shunt for acutely bleeding esophageal varices in cirrhosis.
The mortality rate of bleeding esophageal varices in cirrhosis is highest during the period of acute bleeding. This is a report of a randomized trial that compared endoscopic sclerotherapy (EST) with emergency portacaval shunt (EPCS) in cirrhotic patients with acute variceal hemorrhage. ⋯ EPCS permanently stopped variceal bleeding, rarely became occluded, was accomplished with a low incidence of portal-systemic encephalopathy, and compared with EST, produced greater longterm survival. The widespread practice of using surgical procedures mainly as salvage for failure of endoscopic therapy is not supported by the results of this trial (clinicaltrials.gov #NCT00690027).

The outflow vein of a dysfunctional arteriovenous dialysis access can be used to create a secondary autogenous arteriovenous fistula (SAVF) (type I). In the absence of an outflow vein, an SAVF can still be created elsewhere in the ipsilateral or contralateral extremity by identifying vessels suitable for SAVF creation (type II). But their patency rates and the use of tunneled dialysis catheters during the postoperative period have not been reported in a prospective fashion. ⋯ Although the primary patency rates were not colossal, excellent secondary and cumulative patency rates were observed for SAVF in this study.

Volume status assessment is an important aspect of patient management in the surgical intensive care unit (SICU). Echocardiologist-performed measurement of IVC collapsibility index (IVC-CI) provides useful information about filling pressures, but is limited by its portability, cost, and availability. Intensivist-performed bedside ultrasonography (INBU) examinations have the potential to overcome these impediments. We used INBU to evaluate hemodynamic status of SICU patients, focusing on correlations between IVC-CI and CVP. ⋯ Measurements of IVC-CI by INBU can provide a useful guide to noninvasive volume status assessment in SICU patients. IVC-CI appears to correlate best with CVP in the setting of low (<0.20) and high (>0.60) collapsibility ranges. Additional studies are needed to confirm and expand on findings of this study.

Mortality after trauma has been shown to be influenced by host factors, such as age and preexisting medical conditions (PMCs). The independent predictive value of specific PMCs for in-hospital mortality after adjustment for injury severity, injury pattern, age, and presence of other PMCs has not been fully elucidated. ⋯ Specific PMCs were associated with increased mortality after trauma independent from injury severity and age. Knowledge of the identified relevant PMCs could help the medical team to be able to assess the mortality risk profile of trauma patients in a more detailed and quantifiable way.
