Introduction: Few real-world studies have investigated drug-drug interactions (DDIs) involving non-vitamin-K antagonist oral anticoagulants (NOACs) in patients with nonvalvular atrial fibrillation (NVAF). The interactions encompass drugs inducing or inhibiting cytochrome P450 3A4 and permeability glycoprotein. These agents potentially modulate the breakdown and elimination of NOACs. This study investigated the impact of DDIs on thromboembolism in this clinical scenario. Method: Patients who had NVAF and were treated with NOACs were selected as the study cohort from the National Health Insurance Research Database of Taiwan. Cases were defined as patients hospitalised for a thromboembolic event and who underwent a relevant imaging study within 7 days before hospitalisation or during hospitalisation. Each case was matched with up to 4 controls by using the incidence density sampling method. The concurrent use of a cytochrome P450 3A4/permeability glycoprotein inducer or inhibitor or both with NOACs was identified. The effects of these interactions on the risk of thromboembolic events were examined with univariate and multivariate conditional logistic regressions. Results: The study cohort comprised 60,726 eligible patients. Among them, 1288 patients with a thromboembolic event and 5144 matched control patients were selected for analysis. The concurrent use of a cytochrome P450 3A4/permeability glycoprotein inducer resulted in a higher risk of thromboembolic events (adjusted odds ratio [AOR] 1.23, 95% confidence interval [CI] 1.004-1.51). Conclusion: For patients with NVAF receiving NOACs, the concurrent use of cytochrome P450 3A4/permeability glycoprotein inducers increases the risk of thromboembolic events. [ABSTRACT FROM AUTHOR]

Background: Acute respiratory distress syndrome (ARDS) carries significant morbidity and mortality. No previous studies have investigated the long-term outcomes of ARDS patients in Taiwan. Objective; This study aimed to investigate the survival of ARDS patients after discharge from the hospital in Taiwan. Methods: Medical records from 150 ARDS patients discharged alive from the intensive care unit from January 2004 to June 2009 were reviewed. Survival of these patients was followed for 5 years, and prognostic factors were identified. Results: Cumulative survival rates were 81.4% at 6 months, 79.0% at 1 year, 67.2% at 2 years, and 45.7% at 5 years. Independent prognostic factors influencing both 1- and 5-year survival rates were age, previous lung disease, and disposition after discharge. For 5-year survival, renal disease was also an independent risk factor. Discussion: The mortality rate of ARDS survivors after intensive care unit discharge is still high in Taiwan. Three independent risk factors were found to affect the overall survival of these patients. [ABSTRACT FROM AUTHOR]
