Cross-validation of a Sequential Organ Failure Assessment score-based model to predict mortality in patients with cancer admitted to the intensive care unit.
This study aims to validate the performance of the Sequential Organ Failure Assessment (SOFA) score to predict death of critically ill patients with cancer. ⋯ The SOFA score had good discrimination to predict ICU and hospital mortality. However, the observed underestimation of ICU deaths and unsatisfactory goodness-of-fit test of the model in surgical patients to indicate calibration of the score to predict ICU mortality is advised in this group.

Interrelationship between blood and tissue lactate in a general intensive care unit: a subcutaneous adipose tissue microdialysis study on 162 critically ill patients.
The aim of the study was to study the interrelationship between blood and tissue lactate in critically ill patients with or without shock admitted in a general intensive care unit. ⋯ In critical illness, the detailed dynamics between blood and tissue lactate are affected by the presence of shock. In patients with shock, microdialysis-assessed tissue lactate is higher compared with those without shock and may detect metabolic disturbances before these become evident in the systemic circulation.

Early initiation of continuous renal replacement therapy improves patient survival in severe progressive septic acute kidney injury.
The definition of "early" in terms of continuous renal replacement therapy (CRRT) initiation has not been uniformly used. Therefore, we tried to elucidate whether the timing of CRRT application, based on the interval between the start time of vasopressors infusion and CRRT initiation, was an independent predictor of mortality in the patients with septic acute kidney injury (AKI). ⋯ This retrospective cohort study suggests that early initiation of CRRT may be of benefit. Given the complex nature of this intervention, the ongoing controversies regarding early vs late initiation of therapy in acute and chronic situation, there is an urgent need to develop well-designed clinical trials to answer the question definitely.

Estimation of fluid status changes in critically ill patients: fluid balance chart or electronic bed weight?
Monitoring of fluid balance (FB) can be achieved by subtracting recorded fluid output from input or by measuring changes in body weight (BW). The latter approach is difficult in the critically ill. Recently, hospital beds have become available with the ability to directly weigh patients in the intensive care unit (ICU) patients directly. We sought to compare FB estimates obtained by these 2 methods in a cohort of critically ill patients. ⋯ Obtaining daily weights in ICU patients proved difficult. Compliance was poor. The correlation between changes in BWs and FB was weak. Further studies are required to establish if accurate and reproducible daily weighing of ICU patients is feasible.

Comparative StudyA comparison of seriously ill patients with or without AIDS requiring prolonged mechanical ventilation.
The aim of this study was to compare differences in underlying diagnoses, weaning outcomes, discharge disposition, and survival in prolonged mechanical ventilator (PMV)-dependent patients with and without AIDS. ⋯ AIDS had little effect on weaning success or survival. Successful weaning increased survival regardless of a diagnosis of AIDS. The AIDS patients had more home discharges and fewer to nursing facilities, which likely resulted from the AIDS patients having more acute illnesses leading to PMV than the non-AIDS patients.
