Out-of-hospital characteristics and care of patients with severe sepsis: a cohort study.
Early recognition and treatment in severe sepsis improve outcomes. However, out-of-hospital patient characteristics and emergency medical services (EMS) care in severe sepsis is understudied. Our goals were to describe out-of-hospital characteristics and EMS care in patients with severe sepsis and to evaluate associations between out-of-hospital characteristics and severity of organ dysfunction in the emergency department (ED). ⋯ Out-of-hospital fluid resuscitation occurred in less than one third of patients with severe sepsis, and routinely measured out-of-hospital variables were associated with greater serum lactate and SOFA in the ED.

Comparative StudyThe role of advanced oxidation protein products in intensive care unit patients with acute kidney injury.
Oxidative stress (OS) is an imbalance between the production of oxidizing chemical species and the antioxidant defense. It is known that OS increases in critically ill patients with acute kidney injury (AKI). Measurement of advanced oxidation protein products (AOPPs) has been found to be a simple tool for monitoring OS. ⋯ This is the first study to explore the relationship between severity of AKI and AOPP. In our adult ICU population, AOPP levels were higher in AKI compared with non-AKI critically ill patients. On the other hand, AOPP levels were not found to be a useful biomarker for AKI, as it was unable to identify patients who developed AKI within 24, 48, 76, and 96 hours.

Case ReportsImpact of fulminant hepatic failure in C-reactive protein?
Fulminant hepatic failure (FHF) refers to the rapid development of severe acute liver injury with impaired synthetic function, coagulopathy, and encephalopathy in a person who previously had a normal liver or had a well-compensated liver disease. It is a rare complication in critically ill patients and carries a very bad prognosis. Serum C-reactive protein (CRP), a useful marker of infection, is produced exclusively by the liver. ⋯ In septic patients with FHF, CRP is more a marker of severe liver dysfunction and should not be used as a marker of infection. As a result, in a patient admitted with a very high suspicion of infection and an abnormally low CRP concentration or with a marked CRP decline despite persistent septic shock, severe hepatic failure should be ruled out.

De-escalation after empirical meropenem treatment in the intensive care unit: fiction or reality?
De-escalation of antimicrobial therapy is often advocated to reduce the use of broad-spectrum antibiotics in critically ill patients. However, little data are available on the application of this strategy in daily clinical practice. ⋯ De-escalation after empirical treatment with meropenem was performed in less than half of the patients. Reasons for not de-escalating included the absence of conclusive microbiology and colonization with MRGN.

Randomized Controlled Trial Comparative StudyComparison of 6% hydroxyethyl starch 130/0.4 and saline solution for resuscitation of the microcirculation during the early goal-directed therapy of septic patients.
The aim of this study was to show that 6% hydroxyethyl starch (HES) 130/0.4 achieves a better resuscitation of the microcirculation than normal saline solution (SS), during early goal-directed therapy (EGDT) in septic patients. ⋯ Fluid resuscitation with 6% HES 130/0.4 may have advantages over SS to improve sublingual microcirculation. A greater number of patients would be necessary to confirm these findings.
