Approximate Time to Steady-state Resting Energy Expenditure Using Indirect Calorimetry in Young, Healthy Adults
27 June 2017
A new study in the Frontiers in Nutrition Journal provides evidence on the assessment of the time to reach steady state (SS) during indirect calorimetry in young, healthy adults. The aims of this prospective study are to determine an approximate time to reach SS using open-circuit IC and establish the appropriate duration of SS needed to estimate…
Cardiopulmonary exercise factors predict survival in patients with advanced interstitial lung disease referred for lung transplantation
23 June 2017
The Respiratory Medicine Journal presents a new study demonstrating the prognostic value of CPET test parameters as pre-assessment tool for lung transplant ILD patients. The purpose of this work was to determine if parameters assessed during Cardiopulmonary Exercise Testing (CPET) while using supplemental oxygen can independently predict one-year…
Anthropometric measures are not accurate predictors of fat mass in ALS
22 June 2017
A new article on the Journal of Amyotrophic Lateral Sclerosis (ALS) shows how anthropometric measurements are not effective to measure fat mass in ALS patients. The assessment of Fat Mass in Amyotrophic Latersal Sclerosis patients is important as metabolic abnormalities impact disease progression. Anthropometric measurements include body mass ind…
