Due to studies on calorie requirement in mechanically ventilated critically ill elderly patients are few, and indirect calorimetry (IC) is not available in every intensive care unit (ICU). The aim of this study was to compare IC and Harris-Benedict (HB) predictive equation in different BMI groups. ⋯ IC is the best accurate method for assessing calorie requirement of mechanically ventilated critically ill elderly patients. When IC is not available, using the predictive HB equation is an alternative choice. Calorie requirement can be predicted by HB(ABW) × 1.20-1.43 for critically ill elderly patients according to different BMI groups, or using HB(IBW) × 1.24-1.52 for patients with edema, ascites or no available body weight data.

Metabolic risk factors are associated with liver fibrosis. Whether or not metabolic risk factors affect the severity of liver fibrosis in patients with chronic hepatitis B (CHB), chronic hepatitis C (CHC), or risk factors associated with non-alcoholic fatty liver disease (NAFLD) remains unclear. We aimed to investigate this by transient elastography. ⋯ Elevated BMI was an independent risk factor associated with possible LC across the three different etiologies of CLD. As such, weight loss may be beneficial in these patients.
