Multicenter Study
Rates and Correlates of Relapse Following Emergency Department Discharge for Acute Asthma: A Canadian 20-Site Prospective Cohort Study.
Acute asthma is a common ED presentation. In a prospective, multicenter cohort study, we determined the frequency and factors associated with asthma relapse following discharge from the ED. ⋯ Despite receiving guideline-concordant antiinflammatory treatments at ED discharge, almost one in five patients relapsed within 4 weeks. Female sex, prolonged symptoms, treatment-related factors, and markers of prior asthma severity were significantly associated with relapse. These results may help physicians target more aggressive interventions for patients at high risk of relapse.

Multicenter Study Comparative Study
Risk factors for cardiovascular disease in people with idiopathic pulmonary fibrosis: a population based study.
People with idiopathic pulmonary fibrosis (IPF) have been shown to be at an increased risk for cardiovascular (CV) disease, but reasons for this are unknown. The aim of this study was to compare the prevalence of common CV risk factors in people with IPF and the general population and establish the incidence of ischemic heart disease (IHD) and stroke after the diagnosis of IPF, controlling for these risk factors. ⋯ Several CV risk factors were more prevalent in people with IPF; however, this did not account for the increased rate of IHD in this group of patients.

Multicenter Study Clinical Trial
Endosonography for mediastinal nodal staging of clinical N1 non-small cell lung cancer: a prospective multicenter study.
Patients with clinical N1 (cN1) lung cancer based on imaging are at risk for malignant mediastinal nodal involvement (N2 disease). Endosonography with a needle technique is suggested over surgical staging as a best first test for preoperative invasive mediastinal staging. The addition of a confirmatory mediastinoscopy seems questionable in patients with a normal mediastinum on imaging. This prospective multicenter trial investigated the sensitivity of preoperative linear endosonography and mediastinoscopy for mediastinal nodal staging of cN1 lung cancer. ⋯ Endosonography alone has an unsatisfactory sensitivity to detect mediastinal nodal metastasis in cN1 lung cancer, and the addition of a confirmatory mediastinoscopy is of added value.
