Predictors of change in psychosocial impairment secondary to an eating disorder.

Eating disorders (ED) can significantly impair psychosocial health in patients. However, no published studies have so far used a standardized and specific instrument to evaluate predictive factors in ED-related psychosocial impairment. This prospective cohort study involved 177 patients receiving outpatient treatment for an ED at baseline and 115 patients at the 1-year follow-up.

Predictors of Change in Dyspnea Level in Acute Exacerbations of COPD.

The aim of this study was to identify factors related to changes in dyspnoea level in the acute and short-term periods after acute exacerbation of chronic obstructive pulmonary disease. This was a prospective cohort study of patients with symptoms of acute chronic obstructive pulmonary disease exacerbation who attended one of 17 hospitals in Spain between June 2008 and September 2010. Clinical data and patient reported measures (dyspnoea level, health-related quality of life, anxiety and depression levels, capacity to perform physical activity) were collected from arrival to the emergency department up to a week after the visit in discharged patients and to discharge in admitted patients (short term).

Adaptation and validation of the Spanish version of the Clinical Impairment Assessment Questionnaire.

The Clinical Impairment Assessment (CIA) assesses psychosocial impairment secondary to an eating disorder. The aim of this study was to create and validate a Spanish-language version of the CIA. Using a forward-backward translation methodology, we translated the CIA into Spanish and evaluated its psychometric characteristics in a clinical sample of 178 ED patients.

The Use of Pulse Oximetry to Determine Hypoxemia in Acute Exacerbations of COPD.

Background: There is little evidence that the guideline-recommended oxygen saturation of 92% is the best cut-off point for detecting hypoxemia in COPD exacerbations.

Objective: To detect and validate pulse oximetry oxygen saturation cut-off values likely to detect hypoxemia in patients with aeCOPD, to explore the correlation between oxygen saturation measured by pulse oximetry and hypoxemia or hypercapnic respiratory failure.

Methodology: Cross-sectional study nested in the IRYSS-COPD study with 2,181 episodes of aeCOPD recruited between 2008 and 2010 in 16 hospitals belonging to the Spanish Public Health System.

Predictors of Hospital Length of Stay in Patients with Exacerbations of COPD: A Cohort Study.

Background: Various studies have tried to delimit the predictors of hospital length of stay (LOS) for patients with exacerbated chronic obstructive pulmonary disease (eCOPD), but have been disadvantaged by certain limiting factors.

Objective: Our goal was to prospectively identify predictors of LOS in these patients and to validate our results.

Design: This was a prospective cohort study.

Adaptation and validation of the Metacognition Questionnaire (MCQ-30) in Spanish clinical and nonclinical samples.

Background: The short form of the Metacognitions Questionnaire is a brief multidimensional measure of a range of metacognitive processes and metacognitive beliefs about worry and cognition relevant to vulnerability to and maintenance of emotional disorders. The aim of the study was adapt and validate a Spanish version of the short form of the Metacognitions Questionnaire (MCQ-30) and to evaluate its psychometric properties in clinical and nonclinical samples.

Method: The MCQ-30 was administered to a sample of 316 patients with psychiatric disorders (anxiety, depression, and eating disorders) and to a sample of 169 individuals belonging to the general population.

Predictive score for mortality in patients with COPD exacerbations attending hospital emergency departments.

Background: Limited information is available about predictors of short-term outcomes in patients with exacerbation of chronic obstructive pulmonary disease (eCOPD) attending an emergency department (ED). Such information could help stratify these patients and guide medical decision-making. The aim of this study was to develop a clinical prediction rule for short-term mortality during hospital admission or within a week after the index ED visit.
