Randomized Controlled Trial
Short-term effects of supplemental oxygen on 6-minute walk test outcomes in COPD patients - a randomized, placebo-controlled, single-blind, cross-over trial.
The acute effect of supplemental oxygen during exercise has been shown to differ largely among patients with COPD. It is unknown what factors influence oxygen response. ⋯ In contrast to patients with NOX, patients with HYX and EIH generally benefit from supplemental oxygen by increasing exercise capacity. However, less than one-half of patients reached the threshold of clinically relevant improvements. These oxygen responders were characterized by significantly lower exercise capacity levels.

Accurate and consistent regional lymph node classification is an important element in the staging and multidisciplinary management of lung cancer. Regional lymph node definition sets-lymph node maps-have been created to standardize regional lymph node classification. In 2009, the International Association for the Study of Lung Cancer (IASLC) introduced a lymph node map to supersede all preexisting lymph node maps. Our aim was to study if and how lung cancer specialists apply the IASLC lymph node map when classifying thoracic lymph nodes encountered on CT scans during lung cancer staging. ⋯ Use of older lymph node maps and inconsistencies in interpretation and application of definitions in the IASLC lymph node map may potentially lead to misclassification of stage and suboptimal management of lung cancer in some patients.

Practice Guideline
Use of management pathways or algorithms in children with chronic cough: CHEST Guideline and Expert Panel Report.
Using management algorithms or pathways potentially improves clinical outcomes. We undertook systematic reviews to examine various aspects in the generic approach (use of cough algorithms and tests) to the management of chronic cough in children (aged ≤ 14 years) based on key questions (KQs) using the Population, Intervention, Comparison, Outcome format. ⋯ Compared with the 2006 Cough Guidelines, there is now high-quality evidence that in children aged ≤ 14 years with chronic cough (> 4 weeks' duration), the use of cough management protocols (or algorithms) improves clinical outcomes, and cough management or testing algorithms should differ depending on the associated characteristics of the cough and clinical history. A chest radiograph and, when age appropriate, spirometry (pre- and post-β2 agonist) should be undertaken. Other tests should not be routinely performed and undertaken in accordance with the clinical setting and the child's clinical symptoms and signs (eg, tests for tuberculosis when the child has been exposed).

Review Meta Analysis
Effects of CPAP and MADs on health-related quality of life in OSA: a systematic review and meta-analysis.
Untreated OSA is associated with impaired health-related quality of life (QoL) and excessive daytime sleepiness, which have been shown to improve with treatment. The aim was to compare the effects of CPAP and a mandibular advancement device (MAD) on health-related QoL in OSA. ⋯ CPAP is effective in improving health-related QoL in OSA, and MADs may be just as effective, but further RCTs comparing the two treatments are required.
