Several biological markers of lung injury are predictors of morbidity and mortality in patients with acute respiratory distress syndrome (ARDS). Some lung-protective ventilation strategies, such as low tidal volume, are associated with a significant decrease in plasma biomarker levels compared to the high tidal volume ventilation strategy. The primary objective ...

Abstract Imipenem-resistant Acinetobacter baumannii (IRAB) is a major threat for critically ill patients, including those admitted to burn units. Recent studies have suggested that colonization pressure (the proportion of patients or patient-days harbouring the pathogen of interest) is an important driver of the risk for acquisition of multidrug-resistant organisms. With ...

A large number of adults worldwide suffer from essential hypertension, and because blood pressures (BPs) tend to remain within the same percentiles throughout life, it has been postulated that hypertensive pressures can be tracked from childhood to adulthood. Thus, children with higher BPs are more likely to become hypertensive adults. ...
