Complications of Hemorrhagic Shock and Massive Transfusion-a Comparison Before and After the Damage Control Resuscitation Era.

Trauma remains a leading cause of death, and hemorrhage is the leading cause of preventable trauma deaths. Resuscitation strategies in trauma have changed dramatically over the last 20 years. In the pre damage control resuscitation (DCR) era, we used large volume crystalloid resuscitation and packed red blood cells as the primary resuscitative fluids.

Advanced prehospital resuscitative care: Can we identify trauma patients who might benefit?

Background: Uncontrolled truncal hemorrhage remains the most common cause of potentially preventable death after injury. The notion of earlier hemorrhage control and blood product resuscitation is therefore attractive. Some systems have successfully implemented prehospital advanced resuscitative care (ARC) teams.

Bacterial discrimination by dictyostelid amoebae reveals the complexity of ancient interspecies interactions.

Background: Amoebae and bacteria interact within predator-prey and host-pathogen relationships, but the general response of amoeba to bacteria is not well understood. The amoeba Dictyostelium discoideum feeds on, and is colonized by, diverse bacterial species, including Gram-positive [Gram(+)] and Gram-negative [Gram(-)] bacteria, two major groups of bacteria that differ in structure and macromolecular composition.
