Multicenter StudyValue of procalcitonin, C-reactive protein, and neopterin in exacerbations of chronic obstructive pulmonary disease.
The identification of biological markers in order to assess different aspects of COPD is an area of growing interest. The objective of this study was to investigate whether levels of procalcitonin (PCT), C-reactive protein (CRP), and neopterin in COPD patients could be useful in identifying the etiological origin of the exacerbation and assessing its prognosis. ⋯ According to our results, biomarker levels vary depending on the clinical status. However, the identification of the etiology of infectious exacerbation by means of circulating biomarkers is encouraging, but its main disadvantage is the absence of a microbiological gold standard, to definitively demonstrate their value. High biomarker levels during an exacerbation episode correlate with the short-term prognosis, and therefore their measurement can be useful for COPD management.

Early detection enables the possibility for interventions to reduce the future burden of COPD. The Danish National Board of Health recommends that individuals >35 years with tobacco/occupational exposure, and at least 1 respiratory symptom should be offered a spirometry to facilitate early detection of COPD. The aim, therefore, was to provide evidence for the feasibility and impact of doing spirometry in this target population. ⋯ More than one-third of the recruited subjects had airway obstruction (FEV(1)/ FVC < 0.7). Early detection of COPD appears to be feasible through offering spirometry to adults with tobacco/occupational exposure and at least 1 respiratory symptom.

Adjusting for COPD severity in database research: developing and validating an algorithm.
When comparing chronic obstructive lung disease (COPD) interventions in database research, it is important to adjust for severity. Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines grade severity according to lung function. Most databases lack data on lung function. Previous database research has approximated COPD severity using demographics and healthcare utilization. This study aims to derive an algorithm for COPD severity using baseline data from a large respiratory trial (UPLIFT). ⋯ COPD severity cannot be reliably predicted from demographics and healthcare use. This limitation should be considered when interpreting findings from database studies, and additional research should explore other methods to account for COPD severity.

Why are some evidence-based care recommendations in chronic obstructive pulmonary disease better implemented than others? Perspectives of medical practitioners.
Clinical guidelines for management of patients with chronic obstructive pulmonary disease (COPD) include recommendations based on high levels of evidence, but gaps exist in their implementation. The aim of this study was to examine the perspectives of medical practitioners regarding implementation of six high-evidence recommendations for the management of people with COPD. ⋯ This study of medical practitioner perspectives has indicated areas where significant barriers to the implementation of key evidence-based recommendations in COPD management persist. Developing strategies to target the identified categories provides an opportunity to achieve greater implementation of those high-evidence recommendations in the care of people with COPD.

Meta AnalysisSafety of indacaterol in the treatment of patients with COPD.
Pooled data were analyzed to evaluate the safety and tolerability of indacaterol, a once-daily inhaled long-acting β(2)-agonist for chronic obstructive pulmonary disease (COPD). ⋯ Indacaterol has a good profile of safety and tolerability that is appropriate for the maintenance treatment of patients with COPD.
