TLDR
Studying mechanisms of COPD must now go beyond mere enumeration of separate pathophysiological features, for example airflow limitation, air trapping, and inhomogeneity of ventilation distribution, because accurate phenotypes will lead to better cures and, hence, better prognosis for COPD patients.Abstract:
New insights into cellular and molecular mechanisms have recently emerged, leading respiratory physicians to re-examine and even revise current phenotype classifications of COPD. Studying mechanisms of COPD must now go beyond mere enumeration of separate pathophysiological features, for example airflow limitation, air trapping, and inhomogeneity of ventilation distribution. Rather, how to precisely define various phenotypes of COPD patients should become the main objective for all respiratory physicians, because accurate phenotypes will lead to better cures and, hence, better prognosis for COPD patients. During the last decade respiratory physicians have gained much insight into COPD pathophysiology. Yet we are still far from mastering effective biological tools, including genetic and molecular fingerprints readily available for all patients for easy diagnosis and effective prevention of worsening of COPD.read more

The effects of acupoint-catgut embedment combined with medical treatment on the BODE index scores of chronic obstructive pulmonary disease (COPD) patients
TL;DR: According to these results, acupoint-catgut embedment combined with medical treatment is concluded to be more effective than medical treatment alone in reducing BODE index scores.

New Frontiers in Chronic Obstructive Pulmonary Disease: Where Are We Heading?
TL;DR: The authors of as mentioned in this paper discussed the current understanding of the heterogeneity of COPD, the spectrum of inflammatory pathways in COPD pathophysiology, and the evolving clinical landscape in chronic obstructive pulmonary disease (COPD).

TL;DR: The BODE index, a simple multidimensional grading system, is better than the FEV1 at predicting the risk of death from any cause and from respiratory causes among patients with COPD.

TL;DR: Values below this suggest that further studies, such as split func-tion assessment by quantitative lung scintigraphy and exercisetesting, are warranted, and that all elective surgery Prophylaxis against deep venous throm-bosis should be given before most procedures that will require postoperative bed rest or significantly reduce mobility.

TL;DR: Progression of COPD is associated with the accumulation of inflammatory mucous exudates in the lumen and infiltration of the wall by innate and adaptive inflammatory immune cells that form lymphoid follicles, coupled to a repair or remodeling process that thickens the walls of these airways.

Usefulness of the Medical Research Council (MRC) dyspnoea scale as a measure of disability in patients with chronic obstructive pulmonary disease
TL;DR: The MRC dyspnoea scale is a simple and valid method of categorising patients with COPD in terms of their disability that could be used to complement FEV1 in the classification of COPD severity.

Systemic manifestations and comorbidities of COPD
TL;DR: Treatment of COPD inflammation may concomitantly treat systemic inflammation and associated comorbidities, however, new broad-spectrum anti-inflammatory treatments, such as phosphodiesterase 4 inhibitors, have significant side-effects so it may be necessary to develop inhaled drugs in the future.
