A cross-sectional ...

Phenotyping Exercise Limitation in Systemic Sclerosis: The Use of Cardiopulmonary Exercise Testing

27 January 2016
The relevance of cardiopulmonary exercise test (CPET) systemic sclerosis (SSc) has been analysed in a study published in "Respiration; International Review of Thoracic Diseases" Journal. Exercise impairment is a common symptom of systemic sclerosis (SSc), a disorder which is frequently complicated by cardiopulmonary involvement. This study's a...

Cardiopulmonary exercise tests in rare cardiovascular diseases

26 January 2016
A new study published on the Journal of Rare Cardiovascular Diseases highlight the importance of CPET for this kind of pathologies. Cardiopulmonary exercise testing (CPET) is commonly used in clinical practice for both functional and diagnostic assessments of patients with cardiovascular and pulmonary disease. It provides assessment of the inte...

Chronic obstructive pulmonary disease with lung cancer: Prevalence, severity, and common pathogenesis

25 January 2016
A new study published on the Journal of Cancer Research and Therapy focuses on the relationship between COPD and lung cancer. The aim of this study is to develop a clinical prediction model of contribution of chronic obstructive pulmonary disease (COPD) to the pathogenesis of lung cancer, by reporting the estimated prevalence and severity by GO...

Prognostic value of Cardiopulmonary Exercise Testing in Heart Failure with preserved Ejection Fraction. The Henry Ford HospITal CardioPulmonary EXercise Testing (FIT-CPX) Project

25 January 2016
The American Heart Journal published a new article on the prognostic value of Cardio Pulmonary Exercise Test (CPX) in heart failure (HF) patients. Although cardiopulmonary exercise testing in patients with heart failure and reduced ejection fraction (HFrEF) is well established, there is limited data on the value of CPX variables in patients wit...

The scarce accuracy of REE predictive equations and the importance of REE measurement through indirect calorimetry

25 January 2016
A new study published on American Journal of Critical Care confirms the scarce accuracy of REE predictive equations and the importance of REE measurement through indirect calorimetry. The aim of the study was to compare resting energy expenditure measured by indirect calorimetry (REEIC) with REE calculated by using the Harris-Benedict equation ...

AquaTrainer® Snorkel does not Increase Hydrodynamic Drag but Influences Turning Time

30 December 2015
A new study on the aquatrainer was published on the International Journal of Sport Medicine on the new Aquatrainer snorkel option. This study purpose was to verify if the use of the new AquaTrainer® respiratory snorkel lead to an increase of front crawl hydrodynamic drag and whether the constraint of using an adapted turning technique influence...

Reliability of BOD POD Measurements Remain High Following a Short Duration Low-Carbohydrate Diet

30 December 2015
The reliability of the BOD POD has been again confirmed in a new study from the Sacred Heart University of Connecticut (USA) published in the IJSNEM. The purpose of the present study was to determine whether expected changes in body weight via a three day low-carbohydrate (CHO) diet will disrupt the reliability of air displacement plethysmograp...
