Great variability exists in data collection and coding of variables in studies on traumatic brain injury (TBI). This confounds comparison of results and analysis of data across studies. The difficulties in performing a meta-analysis of individual patient data were recently illustrated in the IMPACT project (International Mission on Prognosis and Clinical Trial Design in TBI): merging data from 11 studies involved over 10 person years of work. ⋯ Recommendations hereto have been proposed by an interagency initiative in the US. These proposals deserve to be taken forward at an international level. This initiative may well constitute one of the most important steps forwards, paving the road for harvesting successful results in the near future.

Multicenter Study
Off hour admission to an intensivist-led ICU is not associated with increased mortality.
Caring for the critically ill is a 24-hour-a-day responsibility, but not all resources and staff are available during off hours. We evaluated whether intensive care unit (ICU) admission during off hours affects hospital mortality. ⋯ The increased mortality after ICU admission during off hours is explained by a higher illness severity in patients admitted during off hours.

Randomized Controlled Trial
Electrical muscle stimulation preserves the muscle mass of critically ill patients: a randomized study.
Critically ill patients are characterized by increased loss of muscle mass, partially attributed to sepsis and multiple organ failure, as well as immobilization. Recent studies have shown that electrical muscle stimulation (EMS) may be an alternative to active exercise in chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients with myopathy. The aim of our study was to investigate the EMS effects on muscle mass preservation of critically ill patients with the use of ultrasonography (US). ⋯ EMS is well tolerated and seems to preserve the muscle mass of critically ill patients. The potential use of EMS as a preventive and rehabilitation tool in ICU patients with polyneuromyopathy needs to be further investigated.

In recent years, the use of the consensus definitions of acute kidney injury (RIFLE and AKIN) in the literature has increased substantially. This indicates a highly encouraging acceptance by the medical community of a unifying definition for acute kidney injury. This is a very important and positive step in the right direction. ⋯ The present review is intended to aid the reader in critically appraising studies using these consensus definitions. Since no single definition will be perfect, a logical next step would be to reconcile existing definitions, moving the medical community towards using a single consensus definition as has been done with sepsis and acute lung injury/acute respiratory distress syndrome. As new data emerge, integration of novel biomarkers into the consensus definition will be a welcome refinement.

In lung cancer surgery, large tidal volume and elevated inspiratory pressure are known risk factors of acute lung (ALI). Mechanical ventilation with low tidal volume has been shown to attenuate lung injuries in critically ill patients. In the current study, we assessed the impact of a protective lung ventilation (PLV) protocol in patients undergoing lung cancer resection. ⋯ Implementing an intraoperative PLV protocol in patients undergoing lung cancer resection was associated with improved postoperative respiratory outcomes as evidence by significantly reduced incidences of acute lung injury and atelectasis along with reduced utilization of intensive care unit resources.
