Based on recent in vitro data, we tested the hypothesis that microarray expression profiles can be used to diagnose sepsis, distinguishing in vivo between sterile and infectious causes of systemic inflammation. ⋯ Sepsis induces changes in mouse leukocyte gene expression that can be used to diagnose sepsis apart from systemic inflammation.

Reliable risk factors for perioperative complications in patients undergoing laparoscopic cholecystectomy would be extremely useful to optimize the clinical management. This study aimed to determine risk factors that can be used for predicting perioperative complications. ⋯ For patients undergoing laparoscopic cholecystectomy (LC), the risk of possible perioperative complications can be estimated based on patient characteristics (gender, age, ASA score, body weight), clinical findings (acute versus chronic cholecystitis), and the surgeon's own clinical practice with LC. So in the likelihood of a case being a "difficult cholecystectomy," an experienced surgeon should be involved both in the decision-making process and during the operation. If LC lasts longer than 2 hours, the cumulative risk for perioperative complications is four times higher compared with an intervention that lasts between 30 and 60 minutes, independent of the surgeon's personal skills with LC.

The technique of total mesorectal excision (TME) increases the risk of anastomotic leakage. The impact of postoperative morbidity of TME on longterm survival has never been described. We retrospectively analyzed factors that might influence survival after TME for rectal cancer, including postoperative morbidity. ⋯ After TME for rectal cancer, pelvic sepsis is a common complication that is associated with increased risk of distant recurrence and decreased longterm survival. Efforts are necessary to decrease postoperative morbidity in surgical treatment of rectal cancer.

Blunt renal artery injuries are rare and no single trauma center can accumulate substantial experience for meaningful conclusions about optimal therapeutic strategies. The purpose of this study was to assess the incidence of renal artery injuries after different types of blunt trauma, and evaluate the current therapeutic approaches practiced by American trauma surgeons and the effect of various therapeutic modalities on hospital outcomes. ⋯ Blunt renal artery injury is rare. Nonoperative management should be considered as an acceptable therapeutic option.

Flame injury confers significant physical and psychologic stress on burn patients. Because most patients and their surrogates lack an understanding of burn injury, and these injuries preclude the meaningful exercise of patient autonomy, informed consent is a challenge for physicians. To better promote patient autonomy, this project collected patient perspectives on the proper duties of patients and physicians after severe burn injury and throughout the recovery phases. ⋯ Patient autonomy may be an unrealistic goal acutely for patients with severe burn injuries. Educational approaches to consent may facilitate patient autonomy, participation in decision making, and adherence to care plan over time. The ethical framework for this approach has been accepted in rehabilitation literature, but this is the first demonstration that relevant patient populations agree with this approach.
