ReviewInfluence of sex on chronic obstructive pulmonary disease risk and treatment outcomes.
Chronic obstructive pulmonary disease (COPD), one of the most common chronic diseases and a leading cause of death, has historically been considered a disease of men. However, there has been a rapid increase in the prevalence, morbidity, and mortality of COPD in women over the last two decades. This has largely been attributed to historical increases in tobacco consumption among women. ⋯ There are also differences in how men and women respond to different therapies. Despite the changing face of COPD, care providers continue to harbor a sex bias, leading to underdiagnosis and delayed diagnosis of COPD in women. In this review, we present the current knowledge on the influence of sex on COPD risk factors, epidemiology, diagnosis, comorbidities, treatment, and outcomes, and how this knowledge may be applied to improve clinical practices and advance research.

Randomized Controlled TrialHow do informal self-care strategies evolve among patients with chronic obstructive pulmonary disease managed in primary care? A qualitative study.
There is much description in the literature of how patients with chronic obstructive pulmonary disease (COPD) manage their breathlessness and engage in self-care activities; however, little of this is from the perspective of those with less severe disease, who are primarily managed in primary care. This study aimed to understand the self-care experiences of patients with COPD who are primarily managed in primary care, and to examine the challenges of engaging in such behaviors. ⋯ Self-care activities evolved spontaneously as participants experienced symptoms of COPD. However, there was a lack of awareness about whether these strategies would impact upon symptoms. Perceptions of COPD by family members posed a challenge to self-care for some participants. Health care professionals should elicit patients' prior disease experiences and utilize spontaneous attempts at disease management in future self-management. These findings have implications for promoting self-management and enhancing quality of life.

ReviewLower airway colonization and inflammatory response in COPD: a focus on Haemophilus influenzae.
Bacterial infection of the lower respiratory tract in chronic obstructive pulmonary disease (COPD) patients is common both in stable patients and during acute exacerbations. The most frequent bacteria detected in COPD patients is Haemophilus influenzae, and it appears this organism is uniquely adapted to exploit immune deficiencies associated with COPD and to establish persistent infection in the lower respiratory tract. ⋯ In addition, we examine the role of H. influenzae in COPD exacerbations, as well as interactions between H. influenzae and respiratory virus infections, and review the role of treatments and their effect on COPD outcomes. This review focuses predominantly on data derived from human studies but will refer to animal studies where they contribute to understanding the disease in humans.

ReviewExamining the relationship between anxiety and depression and exacerbations of COPD which result in hospital admission: a systematic review.
Exacerbations of chronic obstructive pulmonary disease (COPD) are the third largest cause of emergency hospital admissions in the UK. This systematic literature review explored the relationship between the hospitalization rates and the COPD comorbidities, anxiety, and depression. ⋯ Findings from the systematic review have highlighted a need for better recognition and treatment of anxiety and depression amongst individuals with COPD. Ongoing research will develop and test strategies for promoting better management and self-management as a means of reducing hospital admissions.

Comparative Study Observational StudyComparison of clinical features between non-smokers with COPD and smokers with COPD: a retrospective observational study.
Smoking is a major risk factor for chronic obstructive pulmonary disease (COPD); however, the similarities and differences in clinical presentation between smokers and nonsmokers are not fully described in patients with COPD. This study was designed to address this issue in a general teaching hospital in the People's Republic of China. ⋯ Non-smokers with COPD had less impairment in airflow limitation and gas exchange, and a lower prevalence of emphysema, chronic cough, and sputum compared with their smoking counterparts. Tobacco cessation is warranted in smokers with COPD.
