Clinical TrialOne-year non-invasive ventilation in chronic hypercapnic COPD: effect on quality of life.
The data on long-term application of non-invasive ventilation (NIV) in patients with chronic respiratory failure due to COPD are contradictory. We evaluated the effect of the addition of NIV to optimal treatment for 1 year on the quality of life of stable hypercapnic COPD patients. NIV was offered to 49 of 58 initially enrolled consecutive patients, of whom 22 refused NIV and comprised the standard treatment group whereas 27 received NIV. ⋯ No significant improvements were observed in the control group. Patients on NIV spent less days in the hospital compared to controls. NIV when added to optimal medical treatment has beneficial effects on quality of life in stable hypercapnic COPD patients, with additional improvements in arterial blood gases, dyspnea and daytime sleepiness.

Health care utilization of patients with chronic obstructive pulmonary disease and lung cancer in the last 12 months of life.
Previous studies have documented similar levels of end-of-life symptom burden for lung cancer and chronic obstructive pulmonary disease (COPD) patients, yet there has been little comparison of health care utilization during this period. This study contrasts health care utilization by people with COPD and those with lung cancer in the 12 months prior to death. ⋯ Patterns of end-of-life health care utilization differ significantly between people with lung cancer and those with COPD. Further research is needed to establish need and determine gaps in services to better address the needs of people dying with COPD.

ReviewMonitoring of patients with COPD: a review of current guidelines' recommendations.
The goals for the management of COPD are to delay the process of disease progression and alleviate its manifestations. The follow-up of the patients' physical and mental condition is part of best practice management when monitoring routines results in information that contributes to the achievement of management goals. However, the recommendations on monitoring procedures may differ between guidelines and may not be based on scientific evidence. The aim of this article is to review the current guideline recommendations on monitoring routines for COPD. ⋯ Some monitoring routines were recommended frequently, especially follow-up of lung function indices. However, evidence to support the guideline recommendations for the monitoring of patients with COPD is missing. The effect of monitoring on care process and outcomes should be assessed.

Chronic obstructive pulmonary disease and body mass index in five Latin America cities: the PLATINO study.
The body mass index (BMI) is a prognostic factor for chronic obstructive pulmonary disease (COPD). Despite its importance, little information is available regarding BMI alteration in COPD from a population-based study. We examined characteristics by BMI categories in the total and COPD populations in five Latin-American cities, and explored the factors influencing BMI in COPD. ⋯ BMI alterations are common in COPD with no significant differences among countries. Current smoking, age, GOLD stages, education level, residing in Santiago and Montevideo, dyspnea and wheeze were independently associated with BMI in COPD.

Long-term experience after transition from parenteral prostanoids to oral agents in patients with pulmonary hypertension.
Long-term follow-up after transition to oral agents from parenteral prostanoid therapy has not been well characterized. ⋯ Oral transition from parenteral prostanoid agents can be safely done in a selected group of patients. Most patients are able to maintain stable functional class and hemodynamics at long follow up regardless of success of transition attempt. Combination therapy with sildenafil appears to be associated with higher likelihood of successful transitioning.
