Variables Measured During Cardiopulmonary Exercise Testing as Predictors of Mortality in Chronic Systolic Heart Failure
06 May 2016
The predictive strength of CPET parameters of mortality in Heart Failure patients has been studies in this paper in the Journal of American College of Cardiology. The study sought to describe the strength of the association among variables measured during a CPX test and all-cause mortality in patients with HF with reduced ejection fraction (HFrEF…
Accuracy of Prediction Formulae for the Assessment of Resting Energy Expenditure in Hospitalized Children
06 May 2016
A new study confirms the importance of measuring resting energy expenditure in a clinical setting rather than using predictive equations. The study has been published on the Journal of Pediatric Gastroenterology and Nutrition. The study performed a cross-sectional study of 236 infants, children and adolescents consecutively admitted to the Interm…
The impact of Cardiopulmonary Exercise Testing (CPET) on patients over 80 years undergoing elective colorectal cancer surgery
28 April 2016
The role of CPET as a valuable preoperative assessment tool for colorectal cancer resection patients (80 yeas and above) has been examined in this article published on Colorectal Disease Journal. Pre-operative CPET testing in patients over 80 years undergoing elective colorectal cancer resection allows identification of higher risk patients and m…
Winning the war against ICU-acquired weakness new innovations in nutrition and exercise physiology
22 April 2016
A new study published in the Critical Care Journal introduced a new protocol “RISEN"–Recovery from ICU via Surveillance, Exercise, and Nutrition" for post-ICU survivors. The RISEN procotol represents a combination of modern performance-enhancing nutrition, anticatabolic/anabolic interventions, and muscle/exercise testing in order to begin to crea…
Cardiopulmonary Exercise Testing as a Tool for Diagnosing Pulmonary Hypertension in Patients with Dilated Cardiomyopathy
21 April 2016
An interesting article on the Annals of Electrocardiology showing the impact of cardiopulmonary exercise testing (CPX) variables on pulmonary hypertension in dilated cardiomyopathy (DCM). We evaluated the usefulness of crucial CPX variables for detecting elevated pulmonary arterial pressure (PAP) in patients with DCM. The study findings show tha…
The usefulness of cardiopulmonary exercise testing in assessment of patients with suspected coronary artery disease
12 April 2016
A cross-sectional study on the potential value of cardiopulmonary exwercise test in Coronary Artery Disease (CAD) patients has been published in the BMJ Postgraduate Medical Journal. The aim of this study is to assess different parameters of cardiopulmonary exercise testing that can predict the development of myocardial ischaemia in patients with…
Methods for Measuring Lung Volumes: Is There a Better One?
12 April 2016
The accuracy level of three different lung volumes techniques (body plethysmography, radiography with computerized tomography and dilution) were analyzed in the "Respiration - International Journal of Thoracic Medicine". Accurate measurement of lung volumes is of paramount importance to establish the presence of ventilatory defects and give insig…
Exercise Testing: Who, When, and Why?
08 April 2016
A useful review on exercise testing and in particular CPX was published in the American Academy of Physical Medicine and Rehabilitation (AAPMR) Journal. There are different modalities of exercise testing that can provide valuable information to physicians about patient and athlete fitness and cardiopulmonary status. Cardiopulmonary exercise testi…
The Forced Oscillation Technique in Paediatric Respiratory Practice
08 April 2016
The clinical usefulness of Forced Oscillation Technique has been investigated in a scientific article published in Paediatric Respiratory Reviews Journal. The Forced Oscillation Technique (FOT) is a lung function modality based on the application of an external oscillatory signal in order to determine the mechanical response of the respiratory sy…
Predicted versus measured thoracic gas volumes of collegiate athletes made by the BOD POD air displacement plethysmography system
08 April 2016
The differences between measured (with the BOD POD) and predicted Thoracic Gas Volume (TGV) has been investigated in a scientific article on the Applied Physiology, Nutrition, and Metabolism Journal. Measured (TGVm) and predicted (TGVp) thoracic gas volumes from the BOD POD were compared in 33 lean, university athletes. On average, TGVp (3.529 L)…
