Severe sepsis, septic shock, and resulting organ failure appear as the most common cause of death in intensive care medicine. Inflammatory mediators (interleukin-6/IL-6), cell adhesion molecules (intercellular adhesion molecule-1/ICAM-1, vascular cell adhesion molecule-1/VCAM-1), and redox active substances (manganese superoxide dismutase/MnSOD, macrophage migration inhibitory factor/MIF) must be considered to be central hubs in the inflammatory process. However, their exact pathophysiologic function and prognostic value are still poorly understood. ⋯ Our results therefore demonstrate that redox active substances may play an important role in the septic inflammatory response. MIF and MnSOD appear to be early predictors for survival in septic patients.

Comparative Study
The effects of BleedArrest, Celox, and TraumaDex on hemorrhage control in a porcine model.
Hemorrhage is the second leading cause of death in civilian trauma and the leading cause of preventable death in military trauma. The purpose of this study was to examine the effectiveness of three hemostatic agents: BleedArrest, TraumaDex, and Celox. ⋯ BleedArrest, Celox, and TraumaDex were statistically and clinically superior at controlling hemorrhage compared with the standard pressure dressing in the control group.

The aim of the study was to investigate effect of I/R injury on bone tissue and protective role of hyperbaric oxygen precondition (HBO-PC) and ozone precondition (O(3)-PC) on I/R injury by using biochemical analysis. ⋯ It has been shown that levels of MDA and PCO in bone were increased followed by 2 h of ischemia and 22 h of reperfusion period. Ozone-PC and HBO-PC has protective effect against skeletal bone I/R injury by decreasing levels of MDA and PCO, increasing activities of SOD and GSH-Px in rats.

Scars can be devastating and disfiguring, because they are clearly visible, stigmatizing, and permanent reminders of the initial accident or surgical event. Yet, there is still no consensus about the optimal scale or tool to assess the characteristics and evolution. Our aim was to evaluate the clinical importance of scar scales specifically developed for burn scars. ⋯ In contrast to the more objective scar assessment tools, scar scales usually cover more aspects of the scars and are less time-consuming in clinical practice. However, no strong conclusions can be made about their efficacy and validity. In addition to digital photography, scar scales are a valuable instrument in the clinical evaluation and follow-up of scars.

Randomized Controlled Trial
Remote perconditioning reduces myocardial injury in adult valve replacement: a randomized controlled trial.
Remote perconditioning has been proved to reduce myocardial infarction and improve ventricular function in vivo. This study aims to determine the protection of remote perconditioning against cardiac reperfusion injury in patients undergoing valve replacement. ⋯ Remote perconditioning, which is induced by transient lower limb ischemia after aortic cross-clamping, reduces myocardial injury over cardioplegia in adults undergoing selective valve replacement.
