The new 2018 international guidelines for diagnosing usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF) by CT scan split the old pattern possible UIP (2011 IPF guidelines) into two new patterns: probable UIP and indeterminate for UIP. However, the proportions and prognoses of these new CT-scan patterns are not clear. ⋯ The majority of possible UIP diagnoses corresponded to probable UIP, which was associated with a significantly worse prognosis than indeterminate for UIP. This distinction between these two CT patterns emphasizes the relevance of the new international guidelines for the diagnosis of IPF.

Chronic thromboembolic pulmonary hypertension suspicion after pulmonary embolism in cancer patients.
Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe condition which should be screened in patient with persistent dyspnea after pulmonary embolism (PE). After PE, CTEPH incidence was estimated between 0.1 and 9.1% in overall patients. Although cancer is associated with an increased risk of CTEPH, CTEPH incidence is still unknown in cancer patients with PE. We aimed to estimate the frequency CTEPH-likely patients after PE, in cancer patients. ⋯ The frequency of screening for CTEPH seems negligible in PE patients with cancer. Concomitant cancer may affect the clinical suspicion of CTEPH.
