The objective evaluation of obstructive pulmonary diseases with spirometry.
Airway obstruction is variable in asthma, while it is progressive and persistent in chronic bronchitis and emphysema. However, some of the patients presenting with symptoms of chronic airway diseases have clinical features of both asthma and COPD. The group with "Asthma-COPD Overlap Syndrome" (ACOS) phenotype was characterized by definitely irreversible airway obstruction accompanied by symptoms and signs of reversibility. ⋯ Number and percentage distribution of patients by groups were 58 (24.7%) in the asthma group, 70 (29.8%) in the ACOS group, 61 (26%) in the chronic bronchitis group, 32 (13.6%) in the emphysema group, and 14 (6%) in the UNDO group. In conclusion, in our study, the types of obstructive airway diseases could be classified based on clinical, radiological, and pulmonary function test findings into five groups, including asthma, ACOS, chronic bronchitis, emphysema, and both asthma and chronic bronchitis in association with underlying emphysema (emphysema with chronic bronchitis and emphysema with asthma) or the so-called undifferentiated obstruction. We suggest that these patient groups can be determined more accurately by studies that evaluate the association between spirometric FEV1, FEV1/FVC values, and reversibility ratios.

Impact of anemia on short-term survival in severe COPD exacerbations: a cohort study.
Anemia is reported to be an independent predictor of hospitalizations and survival in COPD. However, little is known of its impact on short-term survival during severe COPD exacerbations. The primary objective of this study was to determine whether the presence of anemia increases the risk of death in acute respiratory failure due to severe COPD exacerbations. ⋯ Anemia may be a risk factor for hospital death in severe COPD exacerbations requiring mechanical ventilatory support.

Chronic obstructive pulmonary disease and cognitive impairment in the Chinese elderly population: a large national survey.
Previous studies suggested an association between chronic obstructive pulmonary disease (COPD) and cognitive impairment, mostly in developed countries. There is no evidence available on the association between these two common chronic disorders in the elderly people in People's Republic of China where the population is aging rapidly. ⋯ There was strong association between COPD and cognitive impairment in urban Chinese elderly population.

Impact of GOLD groups of chronic pulmonary obstructive disease on surgical complications.
Chronic obstructive pulmonary disease (COPD) is associated with increased postoperative complications. Recently, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classified COPD patients into four groups based on spirometry results and the severity of symptoms. The objective of this study was to evaluate the impact of GOLD groups on postoperative complications. ⋯ COPD patients in GOLD groups representing a high exacerbation risk have an increased risk of postoperative complications compared to those with low risk.

General practitioners' perceptions of COPD treatment: thematic analysis of qualitative interviews.
In Denmark, the treatment of COPD is mainly managed by general practitioners (GPs). Pulmonary rehabilitation (PR) is available to patients with COPD in the local community by GP referral, but in practice, many patients do not participate in rehabilitation. The aim of our study was to explore 1) GPs' perceptions of their role and responsibility in the rehabilitation of patients with COPD, and 2) GPs' perceptions of how patients manage their COPD. ⋯ Our study suggested a potential self-reinforcing problem with the treatment of COPD being mainly focused on medication rather than on PR. Neither GPs nor patients used a proactive approach. Further, GPs were not fully committed to discuss non-pharmacological treatment and perceived the patients as unmotivated for PR. As such, there is a need for optimizing non-pharmacological treatment of COPD and in particular the referral process to PR.
