COVID-19 can rapidly progress into acute respiratory distress syndrome accompanied by multi-organ failure requiring invasive mechanical ventilation and critical care treatment.

Indirect calorimetry (IC)-guided nutrition might positively affect the clinical outcome of critically ill patients. The objective of this study is to assess the benefit of isocaloric nutrition guided by IC, compared to hypocaloric nutrition, for critically ill patients admitted to the intensive care unit (ICU).

A novel study was published on Current Opinion in Physiology to summarise the impact of COVID-19 infection on pulmonary function and to relate this to disease severity and to the clinico-radiological outcomes.

Premature infants often undergo postnatal growth failure and show an altered body composition (BC) at termequivalent age (TEA) with lower fat-free mass (FFM) and increased fat mass (FM) than infants born at term.

Critical illness demands objective, targeted nutritional therapy to prevent adverse effects of underfeeding/ over feeding. Thus, all recent societal guidelines recommend indirect calorimetry use to determine energy needs.
