Comparative Study
Indirect calorimetry in critically ill mechanically ventilated patients: Comparison of E-sCOVX with the deltatrac.
Indirect calorimetry is recommended to measure energy expenditure (EE) in critically ill, mechanically ventilated patients. The most validated system, the Deltatrac® (Datex-Ohmeda, Helsinki, Finland) is no longer in production. We tested the agreement of a new breath-by-breath metabolic monitor E-sCOVX® (GE healthcare, Helsinki, Finland), with the Deltatrac. We also compared the performance of the E-sCOVX to commonly used predictive equations. ⋯ The E-sCOVX metabolic monitor is not accurate in estimating EE in critically ill mechanically ventilated patients when compared to the Deltatrac, the present reference method. The E-sCOVX overestimates EE with a bias and precision that are clinically unacceptable.

Sarcopenia is known to be a poor prognostic factor after liver transplantation (LT). However, the significance of obesity in combination with sarcopenia (sarcopenic obesity) remains unclear. This study examined the impact of sarcopenic obesity on outcomes after living donor LT (LDLT). ⋯ Patients with sarcopenic obesity showed worse survival after LDLT compared with nonsarcopenic/nonobesity patients.
