Nutritional management of individuals with obesity and COVID-19: ESPEN expert statements and practical guidance

15 November 2021
Among other important risk factors for severe COVID-19 outcomes, obesity has emerged along with undernutrition-malnutrition as a strong predictor of disease risk and severity. Obesity-related excessive body fat may lead to respiratory, metabolic and immune derangements potentially favouring the onset of COVID-19 complications. Early after the o...

Prolonged progressive hypermetabolism during COVID-19 hospitalization undetected by common predictive energy equations

06 August 2021
Indirect calorimetry (IC) is the gold-standard for determining measured resting energy expenditure (mREE) in critical illness. When IC is not available, predicted resting energy expenditure (pREE) equations are commonly utilized, which often inaccurately predict metabolic demands leading to over- or under-feeding. This study aims to longitudina...

Association between body composition at term equivalent age and Bayley scores at 2 years in preterm infants

24 May 2021
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. Early nutrition and growth may impact brain growth. Nevertheless, the evidence relating BC and later neurodevelopment remains sparse....

Indirect calorimetry in critical illness a new standard of care?

20 May 2021
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. Current commercially available indirect calorimeters are often inaccurate, and the inconveniences have led to significant ch...

Cardiopulmonary exercise testing during the COVID-19 pandemic

06 May 2021
The outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has presented a global public health emergency. Although predominantly a pandemic of acute respiratory disease, corona virus infectious disease-19 (COVID-19) results in multi-organ damage that impairs cardiopulmonary function and reduces cardiorespir...

Infant body composition assessment in the neonatal intensive care unit (NICU) using air displacement plethysmography: strategies for implementation into clinical workflow

04 May 2021
Body composition is a sensitive marker of infants’ intra- and extrauterine growth quality that can influence short- and long-term outcomes; including retinopathy of prematurity, bronchopulmonary dysplasia (BPD), metabolic health, cardiovascular and neurodevelopmental outcomes. Low body fat percentage at birth in small and appropriate for gestat...

Point-Counterpoint: Indirect Calorimetry Is Essential for Optimal Nutrition Therapy in the Intensive Care Unit

29 April 2021
A major driver leading to the lack of emphasis on timely ICU nutrition delivery is lack of objective data to guide nutrition care. If we are to ultimately overcome current fundamental challenges to effective ICU nutrition delivery, we must all adopt routine objective, longitudinal measurement of energy targets via indirect calorimetry (IC). Key...
