The complex relationship of serum adiponectin to COPD outcomes COPD and adiponectin.
COPD is a chronic inflammatory disorder with high risk of cardiovascular morbidity and mortality. Adiponectin is a hormone that has anti inflammatory, antidiabetic, and anti atherogenic activities. We investigated the relationship of serum adiponectin to health outcomes in COPD. ⋯ Adiponectin is a complex serum biomarker in COPD that is associated with decreased risk of cardiovascular events but increased risk of respiratory mortality. Because serum adiponectin is not significantly influenced by smoking status, it is a very promising biomarker of cardiovascular outcomes in COPD.

Ventilator-associated pneumonia (VAP) remains a common hazardous complication in patients who are mechanically ventilated and is associated with increased morbidity and mortality.We undertook a systematic review and meta-analysis of randomized controlled trials to evaluate the efficacy and safety of probiotics for the prevention of VAP. ⋯ The limited evidence suggests that probiotics show no beneficial effect in patients who are mechanically ventilated; thus, probiotics should not be recommended for routine clinical application. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity among study designs. Future studies should focus on the safety of probiotics.
