Usefulness and limitations of single-slice computed tomography analysis at the third lumbar region in the assessment of sarcopenia

In the previous issue of Critical Care, Moisey and colleagues [1] report that sarcopenia has potential to serve as a predictor for mortality, discharge disposition, and ICU utilization. Sarcopenia may be mitigated by adequate nutrition supply and early rehabilitation, and so identification of patients with ICU-acquired weakness, who could benefit from rehabilitation, is of fundamental importance [2].
