STOP-Bang questionnaire in patients hospitalized with acute symptomatic pulmonary embolism.

Study Objectives: The STOP-Bang questionnaire is a validated screening tool for obstructive sleep apnea (OSA). We conducted this study to validate it among patients hospitalized with acute symptomatic pulmonary embolism (PE).

Methods: This prospective cohort study enrolled consecutive stable patients with acute PE who underwent an overnight sleep study within 7 days after diagnosis.

Production of Xe and Xe via neutron activation of Xe and Xe at ILL-RHF and NCBJ-MARIA high-flux reactors.

The long-lived xenon isomers Xe and Xe are of interest for the GAMMA-MRI project, which aims at developing a novel imaging modality based on magnetic resonance of polarized unstable tracers. Here, we present the steps leading to and following the production of these two isomers via neutron irradiation of highly-enriched Xe and Xe gas samples at two high-flux reactors, the High-Flux Reactor (Réacteur à haut flux, RHF) at the Institut Laue-Langevin (ILL) and the MARIA reactor at the National Centre for Nuclear Research (NCBJ). We describe the experimental setups and procedures used to prepare the stable xenon samples, to open the irradiated samples, and to transfer xenon isomers into reusable transport vials.

Changes in sleep-disordered breathing from the acute to the stable phase of pulmonary embolism: The ESAET study.

Background: /Objective: Sleep-disordered breathing (SDB) may change from the acute to stable phase of some cardiovascular disorders, but little is known whether these dynamic changes also exist in pulmonary embolism (PE). This study aimed to analyze the changes in the apnea-hypopnea index (AHI) from the acute to stable phase of PE as well as the factors associated.

Patients/methods: We conducted a prospective, longitudinal and multicenter study of consecutive adults requiring hospitalization for non-hypotensive acute PE, with a protocol including clinical, imaging (transthoracic echocardiography [TTE] and computed tomography), blood tests and a sleep study within 48 h of diagnosis of PE.

Nocturnal hypoxemia and prognosis in patients with acute symptomatic pulmonary embolism.

Background: Nocturnal hypoxemia has been associated with cardiovascular and non-cardiovascular morbidity and mortality. This study aimed to investigate the prognostic value of nocturnal hypoxemia among patients with hemodynamically stable acute symptomatic pulmonary embolism (PE).

Methods: We performed an ad hoc secondary analysis of clinical data from a prospective cohort study.
