Observational StudyEffects of intraoperative tidal volume on incidence of acute kidney injury after cardiovascular surgery: A retrospective cohort study.
We performed a retrospective cohort study to evaluate whether intraoperative low tidal volume ventilation reduces the incidence of acute kidney injury (AKI) after cardiovascular surgery. ⋯ This study suggests that intraoperative low tidal volume ventilation during cardiovascular surgery is associated with a decreased incidence of postoperative AKI. Lowering tidal volume might be a simple strategy for reducing AKI incidence after cardiovascular surgery.

Observational StudyCharacteristics and outcomes of critically ill patients with severe hyperammonemia.
To determine the etiology and outcomes of critically ill patients with severe hyperammonemia. ⋯ Critically ill patients with severe hyperammonemia have a high mortality rate and are at risk of developing cerebral edema.

Observational StudyMuscle degradation, vitamin D and systemic inflammation in hospitalized septic patients.
To date, the relationship between systemic inflammation and muscle changes observed by ultrasonography in septic patients in clinical studies is not known. Furthermore, the role of vitamin D on muscle changes in these patients needs to be investigated. ⋯ In septic patients, there is an association between inflammation and changes in muscle mass and strength during ICU stay, which is similar to those observed in experimental studies. In addition, there was an association of vitamin D with recovery of muscle strength during hospitalization.

Bedside dynamic calculation of mechanical power: A validation study.
To develop an equation to calculate the bedside dynamic mechanical power (MPdyn) for modern ventilators using the Work of Breathing ventilator (WOBv) parameter. ⋯ Physicians can easily calculate mechanical power by using MPdyn at the bedside of patients on volume control mode.
