Translation and validation of the Danish version of the postoperative quality of recovery score QoR-15.
Patient perceived quality of recovery is an important outcome after surgery and should be measured in clinical trials. Quality of recovery after surgery and general anaesthesia can be measured by the QoR-15. A high score indicates a good recovery and the score ranges from 0 to 150. The aim of this study was to translate the QoR-15 questionnaire into Danish and do a full psychometric evaluation of the Danish version. ⋯ The QoR-15D has preserved the validity, excellent reliability, high degree of responsiveness and the clinical feasibility of the original English version.

In-hospital vs. 30-day mortality in the critically ill - a 2-year Swedish intensive care cohort analysis.
Standardised mortality ratio (SMR) is a common quality indicator in critical care and is the ratio between observed mortality and expected mortality. Typically, in-hospital mortality is used to derive SMR, but the use of a time-fixed, more objective, end-point has been advocated. This study aimed to determine the relationship between in-hospital mortality and 30-day mortality on a comprehensive Swedish intensive care cohort. ⋯ Choice of mortality end-point influences SMR. The extent of the influence depends on hospital-, ICU- and patient cohort characteristics as well as inter-hospital transfer rates, as all these factors influence the difference between SMR based on 30-day mortality and SMR based on in-hospital mortality.

Kinetics of leukocyte CD11b and CD64 expression in severe sepsis and non-infectious critical care patients.
Leukocyte surface molecules may improve sepsis diagnostics. Our aim was to study whether monocyte and neutrophil CD11b and CD64 expression differs between patients with severe sepsis (including septic shock) and intensive care unit (ICU) controls, and also to investigate the expression kinetics in patient groups. ⋯ Neutrophil CD64 as well as neutrophil and monocyte CD11b expressions were highest in severe sepsis compared with non-infectious conditions, and thus analyses of their expression may be promising approach for sepsis diagnosis in ICU population.

Bupivacaine inhibits endothelin-1-evoked increases in intracellular calcium in model sensory neurons.
Endothelin-1 (ET-1) induces pain-like behavior in animals and man by activating the Gq protein-coupled receptor endothelin-A (ETA ). Activation of ETA receptors on nociceptor membranes evokes intracellular calcium transients and alters membrane Na(+) and K(+) channel and TRPV1 currents, leading to neuronal hyper-excitability manifested by spontaneous and evoked pain behaviors in vivo. In addition to blocking sodium channels, local anesthetics inhibit the Gq protein-coupled signaling of several inflammatory and pro-algesic mediators. In this study, we aimed to investigate the actions of local anesthetics on ETA -mediated increases in intracellular calcium in ND7/104 model sensory neurons. ⋯ Bupivacaine inhibits ETA -mediated calcium transients at clinically relevant concentrations through an intracellular target. The anti-inflammatory and analgesic actions of bupivacaine may be at least partially due to its inhibitory action on Gq -coupled receptors, including ETA.
