Oxidative stress may be involved in occurrence of postoperative delirium (POD) and cognitive dysfunction (POCD). 8-iso-Prostaglandin F2α (8-iso-PGF2α), an isoprostane derived from arachidonic acid via lipid peroxidation, is considered a gold standard for measuring oxidative stress. The present study aimed to investigate the ability of postoperative plasma 8-iso-PGF2α levels to predict POD and POCD in elderly patients undergoing hip fracture surgery. ⋯ Postoperative plasma 8-iso-PGF2α levels may have the potential to predict POD and POCD in elder patients undergoing hip fracture surgery.

Sepsis is a major health care problem, with a significant mortality rate in intensive care units. We evaluated biochemical and inflammatory markers in patients with severe sepsis and septic shock and its association of with mortality rates. ⋯ IL-18 is an important predictor of mortality in humans with both severe sepsis and septic shock, independent of IL-1β.

Insulin-like growth factor-binding protein 7 (IGFBP7) and tissue inhibitor of metalloproteinases-2 (TIMP-2) have demonstrated significantly improved diagnostic performance in assessing risk for acute kidney injury (AKI) compared with existing biomarkers. We present the findings of a multi-site trial to determine the reference intervals for these biomarkers in apparently healthy adults and those with stable chronic morbid conditions without AKI. ⋯ Our investigation showed that urine [IGFBP7]∙[TIMP-2] values were not elevated in patients with stable chronic morbidities who did not have AKI.

Caspase-cleaved Cytokeratin-18 (CCCK-18) is released during apoptosis. Serum CCCK-18 concentrations are associated with prognosis of some critical illness. We investigated the potential relationships between serum CCCK-18 concentrations and disease severity and long-term clinical outcomes after intracerebral hemorrhage. ⋯ Increased serum CCCK-18 concentrations are associated with disease severity and clinical outcomes, suggesting that CCCK represent a novel prognostic predictive biomarker after intracerebral hemorrhage.

Sepsis is a major cause of morbidity and mortality in the emergency department. This study aimed to evaluate the assessment of severity of sepsis by and prognostic value of plasma neutrophil gelatinase-associated lipocalin (NGAL) compared with other widely used biological markers of inflammation in patients with sepsis. ⋯ Plasma NGAL is a valuable biological marker in the assessment of severity and prediction of prognosis of patients with sepsis in the emergency department.
