Measure or estimate energy expenditure in spinal cord injury patients? A comparison of indirect calorimetry and commonly used predictive equations

23 February 2016
A new study published on the Proceedings of the Nutrition Society focuses on energy expenditure after spinal cord injury (SCI) and how commonly used predictive equations tend to overestimate resting metabolic rate (RMR) by 5–32 %. The objective of this study was to measure RMR (m-RMR) with an indirect calorimeter (Quark RMR) and then compare th...

Airways resistance and specific conductance for the diagnosis of obstructive airways diseases

23 February 2016
Respiratory Research Journal published a study on the importance of Airway resistance (RAW) and specific airway conductance (sGAW) measurements through body plethysmography.

The following ...

Resting energy expenditures in haemodynamically compromised cardiac patients

11 February 2016
The importance of measuring and not estimating Resting Energy Expenditure has been confirmed also for critically ill cardiac patients in a pilot trial published on Heart Lung Vessel Journal. The aim of present pilot trial was to evaluate the actual resting energy expenditures (REE) among haemodynamically compromised cardiac patients. The study...

Use of exercise testing in the evaluation of interventional efficacy: an official ERS statement

11 February 2016
A new European Respiratory Society (ERS) Statement has been published in ERJ reviewing the role exercise tests have in patients with chronic respiratory diseases. The review covered studies that report the evaluation or use of the incremental (or ramp) exercise test (IET), the constant work-rate exercise test (CWRET), the 6-min walk test (6MWT)...

Nutrition support practices in critically ill head-injured patients: a global perspective

09 February 2016
A new study on Critical Care Journal describes international nutrition support practices in critically ill head-injured patients. Given that critical illness following head injury is associated with a hypermetabolic state, the study major finding was that nutritional deficits are commonplace and these deficits are associated with a delay to dis...

Cardiopulmonary exercise testing in patients with pulmonary hypertension: clinical recommendations based on a review of the evidence

09 February 2016
Clinical recommendations on the importance of Cardio Pulmonary Exercise Testing in Pulmonary Hypertension patients were published on the Expert Review of Respiratory Medicine. There is an increasing recognition of the potential value of cardiopulmonary exercise testing (CPX) in patients with pulmonary hypertension (PH). Several CPX variables ha...

Resting energy expenditure, macronutrient utilization, and body composition in term infants after corrective surgery of major congenital anomalies: A case-study

09 February 2016
This study published in the Journal of Neonatal-Perinatal Medicine, investigates metabolic changes and nutritional needs during the postsurgical anabolic phase in infants. This analysis explores the associations of resting energy expenditure (REE) and macronutrient utilization with body composition of full-term infants, during catch-up growth a...

Maternal and Fetal Determinants of Neonatal Body Composition

05 February 2016
New study has been published investigating the importance of neonatal body composition as it can influence the development of obesity during childhood and beyond. The aim of the study was to demostrate that fetal growth and maternal factors might influence neonatal fat mass percentage (FM%), independent of birth weight. 194 healthy neonates we...

Lung Function Tests in Preschool Children

05 February 2016
A new study has been published in the Turkish Thoracic Journal reviewing the available techniques for the measurement of lung function in preschool children. This study focuses on two different techniques that can be used in clinical practice, such as the interrupter technique and the forced oscillation technique. For both techniques, normal va...

Ventilatory analysis during 6MWT gives relevant information about exercise limitation in COPD

04 February 2016
A new poster was presented during the 2015 ERS Conference and then published in the European Respiratory Journal, highlighting the importance of ventilatory analysis during the Six Minute Walk Test (6MWT) in COPD patients. The aim of the study was to investigate the respiratory responses during 6MWT in untrained COPD patients. Exercise performa...

Oscillometry complements spirometry in evaluation of subjects following toxic inhalation

03 February 2016
A new study on the European Respiratory Journal highlights the utility to add FOT testing to spirometry in subjects following toxic inhalation (for example the 9/11 World Trade Center disaster in 2001). Although many community members developed respiratory symptoms after World Trade Center destruction in 2001, screening spirometry was usually n...

Comprehensive Profile of Cardiopulmonary Exercise Testing in Ambulatory Persons with Multiple Sclerosis

03 February 2016
The role of cardiopulmonary exercise testing (CPET) to provide a comprehensive assessment of exercise tolerance and responses in multiple sclerosis patients has been examined in a study on the Sports Medicine Journal. The objective of this study was to provide a comprehensive examination of outcome variables from CPET among persons with MS and ...

Clinical Guide for the Use of Metabolic Carts. Indirect Calorimetry—No Longer the Orphan of Energy Estimation

03 February 2016
The importance of measuring Resting Energy Expenditure through Indirect calorimetry has been examined and confirmed in a study published on the ASPEN Nutrition in Clinical Practice Journal. Critically ill patients often require nutrition support, but accurately determining energy needs in these patients is difficult. Energy expenditure is affec...

Body fat differences by self-reported race/ethnicity in healthy term newborns

01 February 2016
The role of race in infant body composition has been investigated in a study published in the Pediatric Obesity journal. This study aimed to assess whether ethnic differences in body fat are present at birth in healthy infants born at term, where body fat is measured using air displacement plethysmography (PEA POD) and fat distribution by skin-...

Test-Retest Reliability of Maximal and Submaximal Gas Exchange Variables in Patients With Coronary Artery Disease

28 January 2016
A study from the Journal of Cardiopulmonary Rehabilitation & Prevention analyses the reliability of gas exchange variables derived from CPET. Gas exchange variables derived from cardiopulmonary exercise tests (CPETs) need to be reliable for evaluating interventions and clinical decision making. Whereas peak oxygen uptake (VO2) has shown to ...

Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient

28 January 2016
The updated Guidelines by Society of Critical Care Medicine (SCCM) and American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) were published in beginning of 2016 on the Journal of Parenteral and Enteral Nutrition. This particular report is an update and expansion of guidelines published by A.S.P.E.N. and SCCM in 2009. The intended u...

Role of cardiopulmonary exercise testing as a risk-assessment method in patients undergoing intra-abdominal surgery: a systematic review

28 January 2016
A review study on cardiopulmonary exercise testing (CPET) used as a preoperative risk-stratification tool for patients undergoing non-cardiopulmonary intra-abdominal surgery has been published on the British Journal of Anesthesia. Previous studies indicate that CPET may be beneficial, but research is needed to quantify CPET values protective ag...

Influence of Body Composition on Lung Function and Respiratory Muscle Strength in Children With Obesity

27 January 2016
A new study published on the Journal of Clinical Medical Research demonstrates how obesity affects lung function and respiratory muscle strength.
