Risk for recurrence of symptomatic upper-extremity deep vein thrombosis in patients without cancer: Analysis of three RIETE cohorts.

Background: The natural history of patients with a pacemaker-related upper-extremity deep vein thrombosis (UEDVT) has not been consistently studied.

Methods: We used the RIETE registry data to compare the outcomes during anticoagulation and after its discontinuation in noncancer patients with symptomatic UEDVT associated with a pacemaker, other catheters, or no catheter. The major outcome was the composite of symptomatic pulmonary embolism or recurrent DVT.

Clinical factors associated with pulmonary aspergillosis in patients with chronic obstructive pulmonary disease.

Objective: To explore the clinical and epidemiological characteristics of chronic obstructive pulmonary disease (COPD) patients with Aspergillus spp. isolation from respiratory samples, and to identify which factors may help us to distinguish between colonisation and infection.

Methods: A retrospective cohort study was performed.
