To the Editor The prospective study by Dr Puthucheary and colleagues1 characterized acute muscle wasting in patients with critical illness. We take exception to the clinical inference that protein delivery was associated with increased muscle wasting. These findings conflict with existing data that higher protein delivery is associated with improved survival, reduced infection, and improved health-related quality of life.2,3
