Observational StudyIgG2 as an independent risk factor for mortality in patients with community-acquired pneumonia.
Mortality in patients with community-acquired pneumonia (CAP) remains high despite improvements in treatment. ⋯ Patients with CAP with IgG2 levels <301 mg/dL had a poorer prognosis and a higher risk of death. Our study suggests the usefulness of IgG2 to predict CAP evolution and to provide support measures or additional treatment.

Incidence and characterization of acute kidney injury after acetaminophen overdose.
Acute kidney injury (AKI) occurs in 2-10% of patients with acetaminophen (APAP) overdose. Elevation in creatinine (SCr) typically occurs 2 to 5 days after ingestion, with a mean peak on day 7, and normalization over a month. However, it remains unclear whether renal impairment occurs without hepatotoxicity. We hypothesized that APAP-associated acute renal failure occurs in patients with and without severe liver dysfunction after APAP overdose. ⋯ Mean day one SCr, maximum change in SCr, and lack of renal failure resolution were higher in patients with higher m-MELD scores. However, patients with low m-MELD scores presented much earlier than patients with high m-MELD scores and 26% developed AKI.

The Intensive care unit specialist: Report from the Task Force of World Federation of Societies of Intensive and Critical Care Medicine.
The role of the critical care specialist has been unequivocally established in the management of severely ill patients throughout the world. Data show that the presence of a critical care specialist in the intensive care unit (ICU) environment has reduced morbidity and mortality, improved patient safety, and reduced length of stay and costs. ⋯ The curriculum to ensure appropriate training around the world is diverse but should ideally meet some minimum standards. The World Federation of Societies of Intensive and Critical Care Medicine has set up a task force to address issues concerning the training, functions, roles, and responsibilities of an ICU specialist.

Comment LetterThe venous-arterial CO2 to arterial-venous O2 content difference ratio: Easy to monitor?
Blood sampling for venous-arterial CO2 to arterial-venous O2 content difference ratio starts to be widely used as a hemodynamic monitoring tool, despite that this calculation remains cumbersome. We propose using indirect calorimetry and respiratory quotient for this purpose, with the same physiological concept.
