Observational StudySepsis Severity Score: An Internationally Derived Scoring System From the Surviving Sepsis Campaign Database.
As the Surviving Sepsis Campaign was assessing patient-level data over multiple countries, we sought to evaluate the use of a pragmatic and parsimonious severity-of-illness scoring system for patients with sepsis in an attempt to provide appropriate comparisons with practical application. ⋯ The Sepsis Severity Score accurately estimated the probability of hospital mortality in severe sepsis and septic shock patients. It performed well with respect to calibration and discrimination, which remained consistent over deciles. It functioned well over international geographic regions. This robust, population-specific evaluation of international severe sepsis patients provides an effective and accurate mortality estimate allowing for appropriate quality comparisons with practical clinical and research application.

Circulating Immature Granulocytes With T-Cell Killing Functions Predict Sepsis Deterioration.
Primary objective was to identify leukocyte subsets that could predict the early evolution of sepsis at 48 hours (i.e., deterioration or stability/improvement). Secondary objectives were to evaluate the prognostic value of leukocyte subsets on mortality and immunosuppressive properties of immature granulocytes. ⋯ Circulating immature granulocytes predicted early sepsis deterioration and were enriched in myeloid-derived suppressor cells which could be responsible for immunosuppression through the induction of T-cell lymphopenia.
