Randomized Controlled Trial Comparative Study
Effects of 2 exercise training programs on physical activity in daily life in patients with COPD.
The effects of different exercise training programs on the level of physical activity in daily life in patients with COPD remain to be investigated. ⋯ Neither training program significantly improved time spent active or energy expenditure in daily life. The training regimens similarly improved quality of life and functional status. Exercise capacity and muscle force significantly improved only in the high-intensity endurance-and-strength group.

Comparative Study
Bacteriological differences between COPD exacerbation and community-acquired pneumonia.
To study the differences in pathogen distribution and antibiotic susceptibility between patients with COPD exacerbation and patients with community-acquired pneumonia, and develop guidance for antibiotic treatment of those conditions. ⋯ P. aeruginosa was the most common pathogen in our patients with COPD exacerbation, and S. pneumoniae was the most common in our patients with community-acquired pneumonia. P. aeruginosa is especially common in the patients with serious or extremely serious COPD.

Multicenter Study
Long-term survival in patients with tracheostomy and prolonged mechanical ventilation in Olmsted County, Minnesota.
An increasing number of patients require prolonged mechanical ventilation (PMV), which is associated with high morbidity and poor long-term survival, but there are few data regarding the incidence and outcome of PMV patients from a community perspective. ⋯ There was a considerable incidence of tracheostomy for PMV. The presence of COPD was an independent predictor of 1-year mortality.
