Randomized Controlled Trial Multicenter Study Observational Study
Clinical Application of the COPD Assessment Test: Longitudinal Data from the CHAIN Cohort.
The COPD Assessment Test (CAT) has been proposed for assessing health status in COPD, but little is known about its longitudinal changes. The objective of this study was to evaluate 1-year CAT variability in patients with stable COPD and to relate its variations to changes in other disease markers. ⋯ One-year longitudinal data show variability in CAT scores among patients with stable COPD similar to mMRC scale score, which is the best predictor of 1-year CAT changes. Further longitudinal studies should confirm long-term CAT variability and its clinical applicability.

Ventilator-associated pneumonia during weaning from mechanical ventilation: role of fluid management.
Pulmonary edema may alter alveolar bacterial clearance and infectivity. Manipulation of fluid balance aimed at reducing fluid overload may, therefore, influence ventilator-associated pneumonia (VAP) occurrence in intubated patients. The objective of the present study was to assess the impact of a depletive fluid-management strategy on ventilator-associated complication (VAC) and VAP occurrence during weaning from mechanical ventilation. ⋯ Using proper competing risk analyses, we found that a depletive fluid-management strategy, when initiating the weaning process, has the potential for lowering VAP risk in patients who are mechanically ventilated.

Do Field Walking Tests Produce Similar Cardiopulmonary Demands to an Incremental Treadmill test in Obese Individuals with Treated Obstructive Sleep Apnea?
Cardiorespiratory fitness, assessed during cardiopulmonary exercise tests by peak oxygen uptake (Vo2pk), is an independent predictor of mortality in obesity. We investigated whether Vo2pk and systemic responses measured during field walking tests were similar to those measured during an incremental treadmill test (ITMT) in obese individuals with treated OSA. ⋯ The ISWT can be used instead of an ITMT and in preference to the 6MWT to assess cardiorespiratory fitness for a cohort of obese people with treated OSA. However, the imprecision of the agreement in Vo2pk between the ITMT and ISWT means they cannot be used interchangeably in an individual.
