Randomized Controlled Trial Comparative Study
Short-term comparative study of high frequency chest wall oscillation and European airway clearance techniques in patients with cystic fibrosis.
High frequency chest wall oscillation (HFCWO) is standard treatment for airway clearance in the USA and has recently been introduced in the UK and Europe. There is little published research comparing HFCWO with airway clearance techniques (ACTs) frequently used in the UK and Europe. The aim of this study was to compare the short-term effects of HFCWO with usual ACTs in patients with cystic fibrosis hospitalised with an infective pulmonary exacerbation. ⋯ During both a finite treatment period and over 24 h, less sputum was cleared using HFCWO than usual ACT. HFCWO does not appear to cause any adverse physiological effects and may influence adherence.

Community-acquired pneumonia (CAP) is the most important clinical infection with a high long-term mortality rate. The aim of this study was to evaluate the value of biomarkers for the prediction of short-term and long-term mortality in CAP. ⋯ MR-proANP and CT-proAVP are powerful tools for the prediction of short-term and long-term risk stratification of patients with CAP.

Review Meta Analysis
COPD and chronic bronchitis risk of indoor air pollution from solid fuel: a systematic review and meta-analysis.
Over half the world is exposed daily to the smoke from combustion of solid fuels. Chronic obstructive pulmonary disease (COPD) is one of the main contributors to the global burden of disease and can be caused by biomass smoke exposure. However, studies of biomass exposure and COPD show a wide range of effect sizes. The aim of this systematic review was to quantify the impact of biomass smoke on the development of COPD and define reasons for differences in the reported effect sizes. ⋯ Despite heterogeneity across the selected studies, exposure to solid fuel smoke is consistently associated with COPD and chronic bronchitis. Efforts should be made to reduce exposure to solid fuel by using either cleaner fuel or relatively cleaner technology while performing domestic work.
