Observational Study
Diagnosis and Management of Temperature Abnormality in ICUs: A EUROBACT Investigators Survey.
Although fever and hypothermia are common abnormal physical signs observed in patients admitted to intensive care units (ICU), little data exist on their optimal management. The objective of this study was to describe contemporary practices and determinants of management of temperature abnormalities among patients admitted to ICUs. ⋯ A wide range of definitions and management practices were reported regarding temperature abnormalities in the critically ill. Documenting temperature abnormality management practices, including variability in clinical care, is important to inform planning of future studies designed to optimize infection and temperature management strategies in the critically ill.

Post-extubation dysphagia is a common and serious problem. The presence of neuromuscular disease at the time of intubation is likely to increase this. ⋯ The number of days ventilated was the single predictor of severe dysphagia and a consequent prolonged hospital stay. Further work to build on these results to unravel the complex interplay between disease, trauma, and other unknown factors will be required.

Protective ventilation by using limited airway pressures and ventilation may result in moderate and prolonged hypercapnic acidosis, as often observed in critically ill patients. Because allowing moderate and prolonged hypercapnia may be considered protective measure for the lungs, we hypothesized that moderate and prolonged hypercapnic acidosis may protect the diaphragm against ventilator-induced diaphragmatic dysfunction (VIDD). The aim of our study was to evaluate the effects of moderate and prolonged (72 hours of mechanical ventilation) hypercapnic acidosis on in vivo diaphragmatic function. ⋯ Moderate and prolonged hypercapnic acidosis limited the occurrence of VIDD during controlled mechanical ventilation in a healthy piglet model. Consequences of moderate and prolonged hypercapnic acidosis should be better explored with further studies before being tested on patients.

Excessive sympathoadrenal activation in critical illness contributes directly to organ damage, and high concentrations of catecholamines damage the vascular endothelium. This study investigated associations between potential drivers of sympathoadrenal activation, circulating catecholamines and biomarkers of endothelial damage and outcome in ST segment elevation myocardial infarction (STEMI)-patients, hypothesizing that the catecholamine surge would reflect shock degree and correlate with biomarkers of endothelial damage. ⋯ In STEMI patients treated with pPCI, catecholamines correlated weakly with biomarkers of endothelial damage, with the strongest correlations and highest adrenaline and syndecan-1 levels in patients with shock. Furthermore, adrenaline and syndecan-1 were weakly but independently associated with mortality and heart failure. Acute myocardial infarction appears to cause significant endothelial cell and glycocalyx injury and a parallel increase in circulating catecholamines.

Editorial Comment
Competing interests declared: early interventions and long-term psychological outcomes.
Survivors of motor vehicle accidents and/or survivors of critical care unit admission are at increased risk of developing post-traumatic reactions such as post-traumatic stress disorder, depression and anxiety. Examining the possible risk factors for the development of these disorders must consider pre-traumatic, peri-traumatic and post-traumatic factors and must do so across domains relating to the trauma, the person and their circumstances. The present study has found propofol administration in the first 72 hours post motor vehicle accident to confer a higher risk for full or partial post-traumatic stress disorder at 6 months. This study highlights concerns that treatment needed acutely post injury may impact adversely on long-term outcome, albeit in a different domain-the psychological.
