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...

The Mayo Clinic Procedures Journal hosts an article describing the project to create a registry of cardiorespiratory fitness (CRF) reference values. Given the importance of CRF in estimating health risk, it is essential to have accurate reference values to know what constitutes a “normal” value. In 2014, a multi-institutional initiative, the Fi...

A new cross-sectional secondary analysis was published in the Journal of Parenteral and Enteral Nutrition (JPEN) focusing on issue related to the indirect calorimetry test in hemodialysis patients. Indirect calorimetry requires a steady state (SS) protocol to determine measured resting energy expenditure (mREE). Achieving stringent criteria for...

A new review study has been published in the Journal of Sports Medicine and Physical Fitness discussing the validity, reliability and principles of operations of existing portable open-circuit spirometry system. Portable open-circuit spirometry systems are widely used in the field of exercise physiology, especially in field settings when freedo...

A new study on the International Journal of Pediatrics and Child Health examines the association between early infant feeding and childhood adiposity. The objective for this study was to assess the relationship between infant feeding (exclusive breastfeeding, mixed feeding and exclusive formula feeding) and childhood adiposity among pre-school ...

A new study on the Nutrition Clinical Practice Journal demonstrates that the assessment of energy expenditure in cystic fibrosis patients requires indirect calorimetry and cannot be predicted by equations. Resting energy expenditure (REE) is increased in patients with cystic fibrosis (CF) with end-stage lung disease due to chronic inflammation ...

This scientific statement is a focused update to the 2012 Joint Scientific Statement on Clinical Recommendations for Cardiopulmonary Exercise (CPX) Testing Data Assessment in Specific Patient Populations from the European Association for Cardiovascular Prevention & Rehabilitation (EACPR) and the American Heart Association (AHA). The purpose...

A new review paper on the Respiratory Medicine Journal confirms the impact of small airways dysfunction and inflammation in adult patients with asthma. This systematic literature review analyzes the prevalence of small airways disease (SAD) in adult patients with asthma, and to ascertain how SAD prevalence compares between different studies whe...

The limited accuracy of currently in use predictive equations for Resting Metabolic rate (RMR) was assessed in a new study on the FASEB Journal. The objective of the present study was to test the validity of established (Harris-Benedict, WHO, Mifflin-St. Jeor) and contemporary (3 meta equations of Sabounchi and colleagues, 1 equation of Nelson ...

This recent paper published on the Polish Pneumology and Allergology Journal provides a clear and useful overview of the importance and the different measurement methods for airway resistance. This paper illustrates characteristics, clinical utility and limitations of main three methods of airway resistance — plethysmography, FOT and the interr...

A new article published on the Respiratory Care Journal highlight the clinical and diagnostic relevance of total lung volumes measurements in addition to spirometry. The present study was performed to evaluate how useful are different pulmonary function test (PFT) parameters to diagnose obstructive lung disease in subjects with a restrictive pa...

An interesting validation study of perioperative CPET as a diagnostic tool for in-hospital morbidity was presented by the UK Perioperative Exercise Testing and Training Society. This study explored the relationship between cardiorespiratory fitness variables derived by cardiopulmonary exercise testing (CPET) and in-hospital morbidity after majo...

Body composition of pregnant women and its influence on infant body composition has been analysed in this scientific paper on the FASEB Journal. This project evaluated the relationship between pregnancy weight gain and maternal body composition (fat mass, fat free mass, percent body fat and percent lean body mass) changes on pregnancy outcome (...

An extremely interesting article on the New York Times of the 16th of May 2016 describes the attempts of sport scientist Prof. Yannis Pitsidalis to produce a revolutionary marathon time. Pitsidalis audacious plan is to use science to facilitate a sub-two-hour marathon by 2019, a decade or two sooner than many experts think possible. A sub 2 hou...
