Review Meta Analysis
Sarcoidosis and cancer risk: systematic review and meta-analysis of observational studies.
An increased cancer risk in patients with sarcoidosis has been suggested, although results are conflicting in a number of case-control and cohort studies. We conducted a systematic review of all available data and performed a meta-analysis to better define and quantify the association between sarcoidosis and cancer. ⋯ The present meta-analysis suggests a significant, though moderate, association between sarcoidosis and malignancy.

Is Quadriceps Endurance Reduced in COPD?: A Systematic Review.
Although the aerobic profile of the quadriceps muscle is reduced in COPD, there is conflicting evidence regarding whether this leads to reduced quadriceps muscle endurance. We, therefore, performed a systematic review of studies comparing quadriceps endurance in individuals with COPD with that in healthy control subjects. ⋯ Quadriceps endurance is reduced in individuals with COPD compared with healthy control subjects, independent of the type of task performed.

SELF-MANAGEMENT FOLLOWING AN ACUTE EXACERBATION OF COPD: A SYSTEMATIC REVIEW.
Self-management (SM) reduces hospital admissions in patients with stable COPD. However, its role immediately post-acute exacerbation (AE) is unclear. The objectives of this review were to describe SM interventions delivered immediately following an AE of COPD (AECOPD) and to conduct a systematic review with meta-analysis of its impact on health-care utilization and health outcomes. ⋯ SM interventions delivered immediately post-AE vary widely and outcome measures are inconsistent, making it difficult to draw strong recommendations regarding its effectiveness. The evaluation of SM interventions, delivered by trained health-care professionals to selected patients and which offer structured follow-up, appears necessary.

Recent work has demonstrated that mechanical forces occurring in the airway as a consequence of bronchoconstriction are sufficient to not only induce symptoms but also influence airway biology. Animal and human in vitro and in vivo work demonstrates that the airways are structurally and functionally altered by mechanical stress induced by bronchoconstriction. ⋯ We review these findings in detail and discuss previous studies in light of this new evidence regarding the influence of mechanical forces in the airways. Furthermore, we highlight potential impacts of therapies influencing mechanical forces on airway structure and function in asthma.
