Correlation between short-term air pollution exposure and unprovoked lung embolism. Prospective observational (Contamina-TEP Group)

Background The aim was to analyze the temporal relationship between short-term air pollution exposure and acute symptomatic unprovoked pulmonary embolism (PE). Patients/methods We performed a prospective, multicenter study in consecutive patients diagnosed with acute symptomatic unprovoked PE from February 2012 to January 2013. We analyzed demographic and clinical data, patients' addresses, meteorological and air pollutants data (PM10, SO2, CO, NO2, ozone emission data). We considered the number of days the patient had symptoms, and the study period constituted the previous 30 days. Likewise, the mean annual data of the reference season were calculated as well as the data of the 30-day stud…

Anti-Factor Xa levels correlate with recurrent venous thromboembolism and clinically relevant bleeding in patients receiving low-molecular-weight heparin

Background: The aim of our study was to investigate whether anti-Xa levels assessed in selected groups of LMWH-treated patients with VTE correlate with the risk of developing thromboembolic or bleeding complications. Methods: Retrospective study, in adult patients treated with anti-Xa-adjusted LMWH analysing the association between anti-Xa activity and recurrent VTE or bleeding. Primary outcomes were symptomatic fatal or nonfatal objectively diagnosed VTE and clinically relevant bleeding (ISTH criteria). Results: From 2007-2017, 192 patients were recruited. Mean age was 62 (SD 18) years and 48% were men. Indications for anti-Xa monitoring were: VTE recurrence under anticoagulation (20.8%), …

Noninvasive ventilation during the weaning process in chronically critically ill patients.

Chronically critically ill patients often undergo prolonged mechanical ventilation. The role of noninvasive ventilation (NIV) during weaning of these patients remains unclear. The aim of this study was to determine the value of NIV and whether a parameter can predict the need for NIV in chronically critically ill patients during the weaning process. We conducted a prospective study that included chronically critically ill patients admitted to Spanish respiratory care units. The weaning method used consisted of progressive periods of spontaneous breathing trials. Patients were transferred to NIV when it proved impossible to increase the duration of spontaneous breathing trials beyond 18 h. 2…
