Randomized Controlled Trial Comparative Study Clinical Trial
[Noninvasive positive pressure ventilation for acute respiratory failure in chronic obstructive pulmonary disease in a general respiratory ward].
In patients with acute exacerbations of chronic obstructive pulmonary disease (COPD), noninvasive ventilatory support (NPPV) with bilevel positive airway pressure (BiPAP) may improve clinical and physiological parameters. The present study used a randomized, prospective design to evaluate the possible benefits of NPPV plus standard therapy versus standard therapy alone in patients admitted with acute hypercapnic respiratory failure in a respiratory unit of a tertiary hospital. ⋯ Early use of noninvasive ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease leads to a more rapid improvement of physiological variables. Moreover, it is possible to apply this treatment in a general respiratory ward.

Comparative Study
[Measuring psychosocial stress at work in Spanish hospital's personnel. Psychometric properties of the Spanish version of Effort-Reward Imbalance model].
Two main models are currently used to evaluate the psychosocial factors at work: the Demand-Control (or job strain) model developed by Karasek and the Effort-Reward Imbalance model, developed by Siegrist. A Spanish version of the first model has been validated, yet so far no validated Spanish version of the second model is available. The objective of this study was to explore the psychometric properties of the Spanish version of the Effort-Reward Imbalance model in terms of internal consistency, factorial validity, and discriminate validity. ⋯ This study is the first one supporting satisfactory psychometric properties of the Spanish version of the Effort-Reward Imbalance model. However, the factorial validity of the extrinsic effort could be questioned.
