This new paper reviews results of previous studies in comparing cardio pulmonary exercise test results achieved by arm cycle ergometer (AC) and to leg cycle ergometer (LC) Despite most of the CPET tests are performed using a treadmill or a leg cycle ergometer, due to disability, co-morbidity, preference or athletic discipline there is a need to...

A new study on the Journal of Clinical Biochemistry and Nutrition examines the importance of monitoring energy metabolism in lung cancer patients. This study aimed to investigate the energy metabolism of patients with lung cancer and the relationship between energy metabolism and proinflammatory cytokines. The resting energy expenditure and re...

The prognostic value of CPET in Idiopathic Dilated Cardiomyopathy (iDCM) patients has been studies in a recent paper published in the International Journal of Cardiology. Although cardiopulmonary exercise testing (CPET) is considered as an important tool in risk stratification of patients with heart failure (HF), prognostic data in the specific...

A recent paper on the European Journal of Clinical Nutrition provides a conceptual historical framework for examining the evolution of energy exchange concepts and measurement methods. Energy exchange is fundamental to life and is a cornerstone in the study of human physiology, metabolism and nutrition. A global effort is underway to further ou...

An interesting study in the International Journal Chronic Obstructive Pulmonary Disease traces the difficulties to differentiate asthma from COPD. Despite the availability of guideline recommendations, diagnostic confusion between COPD and asthma appears common, and often it is very difficult in a patient with airway obstruction to decide wheth...

The European Journal of Clinical Nutrition hosts a new study, which summarizes recent research on the importance of indirect calorimetry in predicting weight gain and obesity. The study reviewed data from indirect calorimetry key metabolic predictors (resting metabolic rate, spontaneous physical activity and respiratory quotient) to gain insigh...

A new statement by the American Heart Association has been recently published suggesting the addition of cardiorespiratory fitness (CRF) for risk classification in patient management and to encourage strategies designed to reduce cardiovascular risk. The purpose of this statement was to review current knowledge related to the association betwee...

An extremely important study has been published in the American Journal of Clinical Nutrition providing body composition reference curves for preterm infants. The objective of this study was to create ADP-based body composition reference curves for preterm infants that approximate, as close as is feasible in live-born infants near birth, the bo...

A new prospective cohort study published on ESPEN's Clinical Nutrition Journal evaluated the role and the feasibility of indirect calorimetry (IC) among patients admitted in intensive care units with diagnosis of acute kidney injury (AKI). A key issue on these patients is that general recommendations suggest to not perform IC during dialysis, b...

New research from the Charité Universitätsmedizin Berlin presents an explorative, single-centre, observational, study assessing body composition (BC) in heart failure (HF) patients using a multi-method, two-compartment approach. The aim of the present study is to assess the association of simple anthropometric indices such as BMI and WHR with F...

A paper published in the British Medical Journal introduces purposes and methodology of a new clinical trial on gait inefficiencies on cerebral palsy adolescents that will be using COSMED wearable metabolic technology. A multicentre randomised controlled trial with a parallel process evaluation is going to be sponsored by Burnel University Lond...

A new study determines, using ADP as a validation method, whether any of the anthropometric indices used historically or currently accurately predict body composition in infants. Body composition is a key metric for assessing nutrition in preterm infants. In many neonatal intensive care units body composition is estimated using anthropometric i...

A new study in the European Respiratory Journal focuses on proper interpretation values for the measured VO2max in elderly patients. This study stresses the importance of the selection of VO2max reference equations, especially for older subjects, and offers clinicians some information to guide their choice. As a matter of fact, predicted VO2max...

A new paper published on Chest Journal investigated the role of Single Breath Nitrogen Washout (N2WO) as a marker to evaluate small airway disease in COPD patients. Given that current functional assessments do not allow a reliable assessment of small airways, One of the major causes of disease in COPD comes from small airways, which could not b...

The reliability of predictive equations versus indirect calorimetry in kidney injury patients has been assessed in this paper published in Annals of Nutrition and Metabolism Journal. There are multiple equations for predicting resting energy expenditure (REE), whose accuracy in severe acute kidney injury (AKI) patients has been examined in this...

The utility of graded exercise tests, cardiopulmonary exercise tests, submaximal walking tests, and other functional assessments (strength, frailty) for Cardiac Rehabilitation have been reviewed in this article of the Journal of Cardiac Rehabilitation and Prevention. This review addresses the role and optimal use of exercise testing in contempo...

The findings of a 12-year research period on elite football professional athletes were published in the Italian journal "Sport Sciences for Health". The aim of the research, conducted by the team of Italian sport scientist Danilo Manari, was to study the relations of maximal oxygen consumption (VO2max) and oxygen consumption at anaerobic thresh...

A new study was published in the American Journal of Medical Sciences highlighting the importance of a submaximal exercise parameter, the OUES, to identify exercise capacity of pulmonary thromboembolism (PE) patients. The objective of this article was to study the oxygen uptake efficiency, an index of cardiopulmonary functional reserve that can...

A new paper tested how acceptable can be among spinal cord injury patients to undertake an indirect calorimetry test with canopy hood. In the absence of reliable predictive equations, indirect calorimetry (IC) remains the gold standard for assessing energy requirements after spinal cord injury (SCI), but it is typically confined to a research s...

The ECSS Journal (EJSS, European Journal of Sport Science) published a new article examining the best methods to measure body composition on paralympic athletes. The study objectives were to describe the body composition of participants in three distinct Paralympic sports and to compare the values of body density and estimated body fat obtained...
