The usefulness of a new indirect calorimeter in critically ill adult patients.

Background & Aims: The use of indirect calorimetry to determine energy requirements is highly recommended in critically ill patients. To facilitate this a new and easy to use calorimeter (Q-NRG+, Cosmed) was developed. The primary aim of our study was to describe the usefulness of this calorimeter and, secondarily, to investigate the agreement between measured and predicted energy needs in a large cohort of critically ill adult patients.

Association between fat-free mass and survival in critically ill patients with COVID-19: A prospective cohort study.

Background: Most critically ill patients with COVID-19 experience malnutrition and weight loss associated with negative clinical outcomes. Our primary aim was to assess body composition during acute and late phase of illness in these patients in relation to clinical outcome and secondary to tailored nutrition support.

Methods: This prospective cohort study included adult critically ill patients with COVID-19.

Nutritional status of patients with COVID-19 1-y post-ICU stay: A prospective observational study.

Objectives: Patients discharged from the intensive care unit (ICU) often experience physical complaints and poor nutritional intake, which negatively affect their nutritional status (NS). The aim of this study was to describe the NS of patients with COVID-19 1-y post-ICU stay.

Methods: This was an observational study of adult patients with COVID-19 1-y post-ICU stay.

Energy expenditure and feeding practices and tolerance during the acute and late phase of critically ill COVID-19 patients.

Background & Aims: Different metabolic phases can be distinguished in critical illness, which influences nutritional treatment. Achieving optimal nutritional treatment during these phases in critically ill patients is challenging. COVID-19 patients seem particularly difficult to feed due to gastrointestinal problems.
