Multicenter Study
Atrial fibrillation after cardiac surgery: a major morbid event?
The purpose of the study was to investigate the incidence, predictors, morbidity, and mortality associated with postoperative atrial fibrillation (AF) and its impact on intensive care unit (ICU) and postoperative hospital stay in patients undergoing cardiac surgery in the Department of Veterans Affairs (VA). ⋯ Atrial fibrillation after cardiac surgery occurs in approximately one third of patients and is associated with an increase in adverse events in all measurable outcomes of care and increases the use of hospital resources and, therefore, the cost of care. Strategies to reduce the incidence of AF after cardiac surgery should favorably affect surgical outcomes and reduce utilization of resources and thus lower cost of care.

Randomized Controlled Trial Clinical Trial
Is hypothermia in the victim of major trauma protective or harmful? A randomized, prospective study.
The purpose of this randomized, prospective clinical trial was to determine whether hypothermia during resuscitation is protective or harmful to critically injured trauma patients. ⋯ Hypothermia increases fluid requirements and independently increases acute mortality after major trauma.

Randomized Controlled Trial Clinical Trial
A prospective, randomized trial of early enteral feeding after resection of upper gastrointestinal malignancy.
The purpose of the study was to determine whether early postoperative enteral feeding with an immune-enhancing formula (IEF) decreases morbidity, mortality, and length of hospital stay in patients with upper gastrointestinal (GI) cancer. ⋯ Early enteral feeding with an IEF was not beneficial and should not be used in a routine fashion after surgery for upper GI malignancies.

The authors retrospectively reviewed their experience with extracorporeal life support (ECLS) in 100 adult patients with severe respiratory failure (ARF) to define techniques, characterize its efficacy and utilization, and determine predictors of outcome. ⋯ Extracorporeal life support provides life support for ARF in adults, allowing time for injured lungs to recover. In 100 patients selected for high mortality risk despite and after optimal conventional treatment, 54% survived. Extracorporeal life support is extraordinary but reasonable treatment in severe adult respiratory failure. Predictors of survival exist that may be useful for patient prognostication and design of future prospective studies.

The purpose of this study was to compare the production of interleukin-10 (IL-10) by peripheral blood mononuclear cells (PBMC) from injured patients and control subjects to determine the responsible cell types and to relate IL-10 production to the occurrence of sepsis. A mouse model of burn injury was used to confirm the human findings and to assess the importance of IL-10 in the lowered resistance to infection after injury. ⋯ Serious injury in humans and in a mouse burn model is followed by increased stimulated production of IL-10 by cells of the immune system. The CD4+ T-helper cells appear to be a major source of IL-10 after injury. In injured patients, increased IL-10 production is correlated with subsequent septic events, and in the burn mouse, IL-10 appears to induce decreased resistance to infection.
