As increased blood lactate concentration is a marker for illness severity in critically ill patients [22], our results are in line with studies showing that membrane depolarization in critically ill patients is directly correlated with severity of illness [6 8].
It remains unclear whether napping is beneficial or a risk factor for or marker of ill health.
Finally, the average number of informative meiosis per marker was 432 for ILL, 200 for UIUC, 670 for USDA and 120 for ROS.
Rank, though, is a consistent marker of ill health.
The objective of this study was to clarify the significance of fecal pH as a marker for assessment of critically ill patients.
By using this additional ICU cohort we clearly show that fractalkine cannot be considered a marker for infection in critically ill patients.
At present, there was a general consensus that a diminished mHLA-DR expression may be a reliable marker for immunosuppression in critically ill patients [ 50, 51].
Only diminished levels of monocyte human leukocyte antigen-DR (mHLA-DR) have until now been reported as being an effective marker for identifying which critically ill trauma patients are susceptible to becoming septic [ 5].
In line with that, Kaplan-Meier curve analysis revealed no role for miR-223 serum measurements in determining patients' long-term prognosis), thus arguing against a strong role of miR-223 as a blood based marker for prediction of critically ill patients' prognosis.
We identified a lower A-FABP level upon admission to the ICU as a prognostic marker for hospital survival in critically ill patients (hazard ratio (HR) 3.92, 95% CI 1.15 to 13.40, P = 0.029), especially in the sepsis patient group (HR 4.82, 95% CI 1.10 to 21.10, P = 0.037).
