COPD
-
There is a paucity of population-based data on COPD prevalence and its determinants in Bangladesh. ⋯ COPD is a highly prevalent and grossly underdiagnosed public health problem in Bangladeshi adults aged 40 years or older. Illiteracy, smoking and biomass fuel burning are modifiable determinants of COPD.

Randomized Controlled Trial Comparative Study
Effects of Whole Body Vibration in Patients With COPD.
Whole body vibration training (WBVT) improves muscle force in healthy subjects. Resistance training (RT) is an important component of a pulmonary program. ⋯ WBVT after 15 min aerobic training enhances 6MWD, Wmax and QoL in COPD patients; however only 30% of patients reached the MCID for 6MWD.

The aims of this study were to test the reproducibility of the 6-minute stepper test (6MST), and evaluate its accuracy in detecting improved functional capacity after pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD). Thirty-five COPD outpatients performed two 6MSTs in the same session, before (6MST1 and 6MST2) and after (6MST3 and 6MST4) PR. The performance, perceived exertion, heart rate and arterial oxygen saturation were measured during each 6MST. ⋯ The perceived exertions were lower after PR (P < 0.02). The systematic improvement of performance (8-10%) during the second 6MST of the each session may be explained from the warming of hydraulic jacks of the stepper and/or learning effect. On the other hand, the 6MST seems sufficiently sensitive to detect functional capacity improvements after PR in patients with COPD.

Randomized Controlled Trial
Walking with Non-Invasive Ventilation Does Not Prevent Exercise-Induced Hypoxaemia in Stable Hypercapnic COPD Patients.
Non-invasive positive pressure ventilation (NPPV) in addition to supplemental oxygen improves arterial oxygenation, walking distance and dyspnea when applied during exercise in stable hypercapnic COPD patients. The aim of the current study was to investigate whether NPPV without supplemental oxygen is capable of preventing severe exercise-induced hypoxemia in these patients when applied during walking. ⋯ The use of NPPV during walking without the application of supplemental oxygen does not prevent exercise-induced hypoxemia in patients with stable hypercapnic COPD.

Chronic Obstructive Pulmonary Disease exacerbations are associated with worsening of airway inflammation, the nature of which may be neutrophilic, eosinophilic, or both. ⋯ This non-intervention study suggests that the cellular nature of bronchitis is largely unpredictable and needs to be examined at each COPD exacerbation This has important implications in choosing the appropriate therapy. Future intervention studies would provide further evidence.
