Randomized Controlled TrialFluticasone propionate/formoterol for COPD management: a randomized controlled trial.
To evaluate fluticasone propionate/formoterol (FP/FORM) in COPD. ⋯ FP/FORM did not reduce exacerbation rates versus FORM. Numerical benefits were observed with FP/FORM 500/20 µg versus FORM for secondary variables, including lung function, EXACT exacerbations, SGRQ-C and EXACT-respiratory symptoms total and breathlessness scores. Few efficacy differences were evident between FP/FORM 250/10 µg and FORM. Pneumonia was more frequent in FP/FORM-treated patients, although the absolute difference was low. Adverse events were otherwise similar between treatments.

Multicenter Study Observational StudyCOPD patients' self-reported adherence, psychosocial factors and mild cognitive impairment in pulmonary rehabilitation.
In addition to clinical comorbidities, psychological and neuropsychological problems are frequent in COPD and may affect pulmonary rehabilitation delivery and outcome. The aims of the study were to describe a COPD population in a rehabilitative setting as regards the patients depressive symptoms, anxiety, mild cognitive impairment (MCI) and self-reported adherence and to analyze their relationships; to compare the COPD sample MCI scores with normative data; and to investigate which factors might predict adherence to prescribed physical exercise. This was a multicenter observational cross-sectional study. ⋯ Depression was related to autonomous long-term oxygen therapy modifications, disease perception, family support and MCI. In the multivariate logistic regression analysis, higher BMI, higher depression and lower anxiety predicted lower adherence to exercise prescriptions (P=0.0004, odds ratio =0.796, 95% CI =0.701, 0.903; P=0.009, odds ratio =0.356, 95% CI =0.165, 0.770; and P=0.05, odds ratio =2.361, 95% CI =0.995, 5.627 respectively). In COPD patients, focusing on pharmacological and nonpharmacological adherence enhance the possibility of tailored pulmonary rehabilitation programs.

It is increasingly acknowledged that delays in the diagnosis of chronic inflammatory lung conditions have hampered our understanding of pathogenesis and thus our ability to design efficacious therapies. This is particularly true for COPD, where most patients are diagnosed with moderate-to-severe airflow obstruction and little is known about the inflammatory processes present in early disease. There is great interest in developing screening tests that can identify those most at risk of developing COPD before airflow obstruction has developed for the purpose of research and clinical care. ⋯ As the equipment that delivers tests of small airways become more widely available, reference ranges are emerging and newer methodologies specifically seek to address variability and difficulty in test performance. Moreover, there is evidence that while tests of small airways may not be helpful across the full range of established disease severity, there may be specific groups (particularly those with early disease) where they might be informative. In this review, commonly utilized tests of small airways are critically appraised to highlight why these tests may be important, how they can be used and what knowledge gaps remain for their use in COPD.

Multicenter StudyA cross-sectional survey of night-time symptoms and impact of sleep disturbance on symptoms and health status in patients with COPD.
Sleep disturbance has been termed the forgotten dimension of chronic obstructive pulmonary disease (COPD), but it is clinically important as most patients are affected. This study examined the incremental burden of illness associated with sleep disturbance in COPD, with reference to health status and disease impact, and the degree of concordance between physicians and patients in reporting night-time COPD symptoms. ⋯ Night-time symptoms and sleep disturbance are common among patients with COPD, and sleep disturbance has a detrimental impact on COPD symptoms and health status.

Randomized Controlled TrialIs cardiac autonomic modulation during upper limb isometric contraction and Valsalva maneuver impaired in COPD patients?
To evaluate the heart rate variability (HRV) indices and heart rate (HR) responses during isometric contraction (IC) and Valsalva maneuver (VM) in COPD patients. ⋯ COPD patients responded properly to the upper limb IC and to the VM; however, HR recovery during VM was impaired in these patients. The severity of the disease and MIP were associated with increased parasympathetic modulation and higher chronotropic response.
