Sirtuins (SIRT), first discovered in yeast as NAD+ dependent epigenetic and metabolic regulators, have comparable activities in human physiology and disease. Mounting evidence supports that the seven-member mammalian sirtuin family (SIRT1-7) guard homeostasis by sensing bioenergy needs and responding by making alterations in the cell nutrients. Sirtuins play a critical role in restoring homeostasis during stress responses.

We gathered data on 50 nonintubated surgical patients in a 10-bed surgical ICU (SICU) who met physiologic inclusion criteria beginning in May 2008 (A group). In January 2009, we began mandatory entry of computerized mobility orders as part of a standardized ICU order set.

Identification of those with VAP is important both in immediate clinical decision making as well as for the epidemiologic evaluation of the disease and benchmarking of rates across institutions with variable practice patterns. Despite this, controversy exists over the optimal method of VAP diagnosis.

However, few data are available on the use of these indications for patients with blunt injuries. In a retrospective study (June 1996 to July 2001), we compared the indications of urgent thoracotomy after blunt injury and penetrating injury in patients who underwent thoracotomy within 24 hours of hospital admission at our institution.
