More than 40 percent of patients being treated for COPD at a federally funded clinic did not have the disease, researchers found after evaluating the patients with spirometry, the diagnostic "gold standard" for chronic obstructive pulmonary disease.

Treatment with an Alpha-1 proteinase inhibitor (A1-PI), a naturally occurring protein that protects lung tissue from breakdown and protects the lung's elasticity, is effective in slowing the progression of emphysema in patients with Alpha-1 antitrypsin deficiency (AATD), a life-threatening genetic disorder, according to a new study presented at the 2013 American Thoracic Society International Conference.

Depression is common in patients with chronic obstructive pulmonary disease (COPD) and has been linked with disease severity and impaired quality of life. Now, for the first time, researchers at the University of Pittsburgh have linked the systemic inflammation associated with COPD with depression in these patients.

Chronic obstructive pulmonary disease is primarily associated with the respiratory symptoms that are its hallmark, but in fact, patients who struggle with the disease also experience significant amounts of chronic pain.

The negative effects of poorly controlled asthma symptoms on sleep quality and academic performance in urban schoolchildren has been confirmed in a new study.

People who are consistently exposed to both wood smoke and tobacco smoke are at a greater risk for developing chronic obstructive pulmonary disease and for experiencing more frequent and severe symptoms of the disease, as well as more severe airflow obstruction, than those who are exposed to only one type of smoke, according to the results of a new population-based study conducted by researchers in Colombia.

The Global Initiative for Chronic Obstructive Lung Disease classification of chronic obstructive pulmonary disease predicts mortality better than the 2011 ABCD scoring system, report Norwegian researchers.

More attention should be given to patients who have chronic obstructive pulmonary disease and concomitant asthma, after a study showed that nearly one-fifth of patients with COPD fall into this subtype.

Research suggests that using quieter streets with less traffic exposes city cyclists to lower levels of air pollution than using more congested routes, although wind-speed has a significant influence on levels of pollution exposure experienced each day.

Chronic obstructive pulmonary disease is underdiagnosed and undertreated among lung cancer patients in China, study results show.

Children with asthma demonstrate significantly increased serum levels of the adipokine apelin-12, researchers report.

Screening smokers with spirometry for chronic obstructive pulmonary disease picks up more cases than symptom-based detection, research suggests.

Severity of emphysema, as measured by computed tomography (CT), is a strong independent predictor of all-cause, cardiovascular, and respiratory mortality in ever-smokers with or without chronic obstructive pulmonary disease (COPD), according to a study from researchers in Norway. In patients with severe emphysema, airway wall thickness is also associated with mortality from respiratory causes.

A once-daily, inhaled, fixed-dose dual bronchodilator combination has greater efficacy than twice-daily salmeterol plus fluticasone for the treatment of chronic obstructive pulmonary disease, results of the phase III ILLUMINATE trial show.

The age-adjusted prevalence of chronic obstructive pulmonary disease (COPD) varies considerably within the United States, from less than 4 percent of the population in Washington and Minnesota to more than 9 percent in Alabama and Kentucky.

Around one-fifth of patients consulting their primary care physician for acute cough could have undiagnosed asthma or chronic obstructive pulmonary disease, show the results of a pan-European study.

Four finalists have been selected in the My Air, My Health Challenge, sponsored by the National Institutes of Health (NIH) and its challenge partners. Each finalist will receive $15,000, and will transform their designs to measure air pollutants and related physiological measurements into working systems. One overall winner will receive a cash award of $100,000 to be announced in June 2013.

Older patients with chronic obstructive pulmonary disease are at increased risk for carotid artery plaque formation and for the presence of vulnerable plaques with a lipid core, according to a new study from researchers in the Netherlands.

A simple, five-question patient-administered survey (COPD-PS) may lead to increased diagnoses of chronic obstructive pulmonary disease (COPD).

Exposure to ambient air pollution from traffic during infancy is associated with lung function deficits in children up to eight years of age, particularly among children sensitized to common allergens, according to a new study.
