Observational StudyPosttraumatic stress disorder symptoms in close relatives of intensive care unit patients: Prevalence data resemble that of earthquake survivors in Chile.
Posttraumatic stress disorder (PTSD) in relatives of intensive care unit (ICU) patients has not been fully described. We studied potential relationships between PTSD and specific patients' conditions and relatives' psychologic characteristics. ⋯ Close relatives of patients admitted to the ICU experience a high prevalence of PTSD during and after hospitalization. Individual patient factors such as severity, age, and being on MV increase the occurrence of PTSD, as well as sex and baseline anxiety levels of caregivers. Preventative measures could be devised for this particular high-risk population.

Observational StudyMortality in chronically critically ill patients: Expanding the use of the ProVent score.
The purpose of the study is to look at the performance of the Prognosis for Prolonged Ventilation (ProVent) score with a short-term outcome as well as when used earlier during the course of prolonged mechanical ventilation (MV). ⋯ The ProVent score can be used for short-term prognosis (mortality in the ICU) and earlier in the evaluation of CCI patients.

Multicenter Study Observational StudyDecrease of oxidative phosphorylation system function in severe septic patients.
The comparison of oxidative phosphorylation system capacities between septic patients and control subjects has been scarcely analyzed and only in studies with small sample size (fewer than 40 septic patients and 40 controls). Thus, the objective of this study was to compare platelet respiratory complex IV (CIV) activity between severe septic patients and healthy individuals in a larger series (including 198 severe septic patients and 96 healthy controls). ⋯ The major finding of our work, involving the largest series to date of severe septic patients with data on oxidative phosphorylation system capacity, was that surviving and nonsurviving septic patients showed lower platelet CIV-specific activity during the first week of sepsis than healthy controls.

Observational StudyProlonged pulmonary support after cardiac surgery: incidence, risk factors and outcomes: a retrospective cohort study.
Post-cardiac surgery pulmonary dysfunction may be underreported. Therefore, we evaluated associated risk factors for prolonged pulmonary support after cardiac surgery. ⋯ We identified risk factors for prolonged mechanical ventilation and supplemental O2 use, described an association with increased adverse outcomes, and determined that persistent pulmonary edema on day 2 was the most likely radiological finding.

Comparative Study Observational StudyComparison of point-of-care hemostatic assays, routine coagulation tests, and outcome scores in critically ill patients.
The purposes of the study are to compare point-of-care (POC) hemostatic devices in critically ill patients with routine laboratory tests and intensive care unit (ICU) outcome scoring assessments and to describe the time course of these variables in relation to mortality rate. ⋯ All POC and routine laboratory tests showed a hypocoagulative response in nonsurvivors compared to survivors. ReoRox was better than ROTEM and Multiplate at detecting differences between surviving and nonsurviving ICU patients. However, Simplified Acute Physiology Score 3 showed the best association to mortality outcome.
