Measured (TGVm) and predicted (TGVp) thoracic gas volumes from the BOD POD were compared in 33 lean, university athletes. On average, TGVp (3.529 ...

Estimation of energy expenditure using prediction equations in overweight and obese adults: a systematic review

08 April 2016
The usefulness of predictive equations of REE in healthy obese subjects has been analysed in this literature review published in the Journal of Human Nutrition and Dietetics from the British Dietetic Association. Estimates of energy requirements are needed in weight management and are usually determined using prediction equations. The objective...

Comparison of multiple methods to measure maternal fat mass in late gestation

01 April 2016
The American Journal of Clinical Nutrition published a study demonstrating the validity of ADP measurements of fat mass in pregnant women at term. Measurements of maternal fat mass (FM) are important for studies of maternal and fetal health. Common methods of estimating FM have not been previously compared in pregnancy with measurements using m...

Cardiopulmonary Exercise Testing-Based Algorithm and Its Usefulness in Clinical Cardiology

24 March 2016
The Journal of Patient-centred Research and Reviews published a study that validation a simplified diagnostic algorithm involving only six CPX variables. The study start from the asumption that CPX testing is underutilized by cardiologists due to complex diagnostic algorithms involving up to 30 variables as well as lack of validation studies. I...

Diffusion Capacity and Mortality in Patients With Pulmonary Hypertension Due to Heart Failure With Preserved Ejection Fraction

24 March 2016
The prognostic importance of lung diffusion capacity testing in pulmonary hypertension patients has been analysed in this study published in the Journal of the American College of Cardiology. This study sought to investigate the prognostic importance of a low diffusion capacity of the lung for carbon monoxide (DLCO) in patients with a catheter-...

Minimum Time to Achieve the Steady State and Optimum Abbreviated Period to Estimate the Resting Energy Expenditure by Indirect Calorimetry in Healthy Young Adults

18 March 2016
The Nutrition in Clinical Practice Journal published an interesting article on the optimum abbreviated period for measurement of indirect calorimetry. This study aimed to determine the acclimation time required to achieve the REE steady state during a 30-minute IC measurement and to define the optimum abbreviated measurement period in the stead...

The Vital Capacity Is Vital: Epidemiology and Clinical Significance of the Restrictive Spirometry Pattern

18 March 2016
An overview on the significance of Restrictive Spirometry Pattern has been published in the Chest Journal, official pubblication of the American College of Chest Physicians. The restrictive spirometry pattern (RSP) is characterized by decreased FEV1 and FVC but a preserved FEV1/FVC ratio. Epidemiologic research has revealed a substantial portio...

Cardiopulmonary Exercise Testing in Patients with Asymptomatic or Equivocal Symptomatic Aortic Stenosis: Feasibility, Reproducibility, Safety and Information Obtained on Exercise Physiology

18 March 2016
A new study on Cardiology Journal investigates the role of the information obtained by Cardiopulmonary Exercise test in patients with limited aortic valve area (AVA). The aim of this study was to determine the feasibility, reproducibility, safety and information obtained on exercise physiology from cardiopulmonary exercise testing (CPX) in pati...

Oxygen uptake efficiency slope and peak oxygen consumption predict prognosis in children with tetralogy of Fallot

15 March 2016
The Preventive Cardiology Jornal published a new study investigating the prognostic value of CPET in patients with tetralogy of Fallot. Oxygen uptake efficiency slope (OUES) and peak oxygen consumption (VO2peak) are exercise parameters that can predict cardiac morbidity in patients with numerous heart diseases. But the predictive value in patie...

Does the use of indirect calorimetry change outcome in the ICU? Yes it does

04 March 2016
A new study appears on the "Current Opinion on Clinical Nutrition and Metabolic care Journal" highlighting the importance of monitoring nutrition and metabolic status of ICU patients.   The purpose of this review is to highlight recent findings on metabolic monitoring and possible beneficial effects of an adequate nutrition therapy, based on i...

Cardiopulmonary exercise testing versus spirometry as predictors of cardiopulmonary complications after colorectal surgery

29 February 2016
A study on the European Surgery Journal compares the preoperative predictive value of spirometry and CPET in patients scheduled to undergo elective colorectal surgery. The aim of the study is to determine the predictive value of spirometry and cardiopulmonary exercise testing (CPET) preoperatively in patients scheduled to undergo elective color...

Resting energy expenditures in chronic kidney disease patients before, during, and after hemodialysis

29 February 2016
A study in the Journal of Medical Technology and Physical Therapy investigates the variability of Resting Energy Expenditure in hemodialysis patients. Hemodialysis procedures of a long duration of 3–4 h may possibly affect resting energy expenditure (REE), leading to post-dialysis symptoms in chronic kidney disease (CKD). The purpose of this st...
