Electroencephalogram (EEG) monitoring in patients treated with therapeutic hypothermia after cardiac arrest may assist in early outcome prediction. Quantitative EEG (qEEG) analysis can reduce the time needed to review long-term EEG and makes the analysis more objective. In this study, we evaluated the predictive value of qEEG analysis for neurologic outcome in postanoxic patients. ⋯ We introduced a combination of qEEG measures expressed in a single number, the CRI, which can assist in prediction of both poor and good outcomes in postanoxic patients, within 24 hours after cardiac arrest.

Prior reports suggest that restrictive ICU visitation policies can negatively impact patients and their loved ones. However, visitation practices in US ICUs, and the hospital factors associated with them, are not well described. ⋯ In 2008 the overwhelming majority of US ICUs in this study had restrictive visitation policies. Wide variability in visitation policies suggests that further study into the impact of ICU visitations on care and outcomes remains necessary to standardize practice.

Reduced monocyte human leukocyte antigen (mHLA)-DR surface expression in the late phase of sepsis is postulated as a general biomarker of sepsis-induced immunosuppression and an independent predictor of nosocomial infections. ⋯ Patients with sepsis display a diminished expression of HLA-DR at the monocyte surface as well as in the gene expression at the mRNA level. The mRNA expression level of HLA-DRA monitored by qRT-PCR correlates highly with surface expression of HLA-DR and appears to be a possible future biomarker for evaluation of immunosuppression in sepsis.

A week seems to be weak: tailoring duration of antibiotic treatment in Gram-negative ventilator-associated pneumonia.
The optimal length of antimicrobial therapy has not been extensively studied for a great majority of infections and, in critically ill patients affected by ventilator-associated pneumonia, is a persisting and unsolved issue confronting clinicians. The integration of biomarkers, clinical judgment, and microbiologic eradication might help to define a shorter duration for some ventilator-associated pneumonia episodes due to non-fermenting Gram-negative bacilli, but until these strategies are implemented in clinical practice for individualizing antibiotic treatment, a short-course duration does not seem to tailor a long benefit.
