LABA/LAMA Combination Therapy More Effective for COPD Patients with Exercise Intolerance

Clinicians grappling with the pharmacologic management of COPD in patients complaining of exercise intolerance or dyspnea now have new guidance. The American Thoracic Society has published an official clinical practice guideline in which a panel of experts strongly recommended LABA/LAMA combination therapy over LABA or LAMA alone. The complete guideline detailing all the recommendations was posted online ahead of print in the American Journal of Respiratory and Critical Care Medicine.

UK Study Highlights Importance of Spirometry in Diagnosing COPD, Versus Over-Reliance on Medical Imaging

A UK study of patients participating in low-dose CT lung cancer screening highlights the importance of spirometry (breathing tests) in the assessment of possible chronic obstructive pulmonary disease (COPD), and demonstrates that over-reliance on radiological changes alone may result in detection of clinically insignificant disease. The new study is published online in the Annals of the American Thoracic Society.

Traditional Biomass Stoves, Used Widely in Developing Nations, Shown to Elevate Indoor Air Pollutants, Cause Lung Inflammation

Traditional stoves that burn biomass materials and are not properly ventilated, which are widely used in developing nations where cooking is done indoors, have been shown to significantly increase indoor levels of harmful PM2.5 (miniscule atmospheric particulates) and carbon monoxide (CO) and to stimulate biological processes that cause lung inflammation and may lead to chronic obstructive pulmonary disease (COPD), according to new research published online in the Annals of the American Thoracic Society.

New hope for COPD patients possible with in-home device

In a new paper published Feb. 4 in JAMA, Mayo Clinic researchers describe the benefits of in-home noninvasive ventilation therapy ― which includes a type referred to as bilevel positive airway pressure, or BiPAP ― for many patients with chronic obstructive pulmonary disease (COPD). The team identified a number of benefits, including reduced mortality, fewer hospital admissions, lower risk of intubation, improved shortness of breath, and fewer emergency department visits.

Wrist-Worn Step Trackers are as Accurate in Predicting Patient Health as Standardized Clinical Walking Tests, Researchers Find

In a new study, researchers at Intermountain Healthcare in Salt Lake City found that steps measured through a step tracker worn on the wrist can be used to estimate exercise capacity and determine the health status of patients, rather than the standardized six-minute walk distance test, which is usually conducted in a clinical setting.
