The clinical outcomes of COVID-19 critically ill patients co-infected with other respiratory viruses: a multicenter, cohort study.

Background: Previous studies have shown that non-critically ill COVID-19 patients co-infected with other respiratory viruses have poor clinical outcomes. However, limited studies focused on this co-infections in critically ill patients. This study aims to evaluate the clinical outcomes of critically ill patients infected with COVID-19 and co-infected by other respiratory viruses.

Real-World Evaluation of the Safety and Effectiveness of Apixaban & Rivaroxaban Lead-in Dosing Compared to Parenteral Lead-in Dosing in the Treatment of Venous Thromboembolism: A Multi-Center Retrospective Cohort Study.

Background: Although parenteral anticoagulation lead-in is not recommended with apixaban and rivaroxaban, parenteral anticoagulation is often used to replace apixaban or rivaroxaban lead-in doses for the initial phase treatment of VTE. Thus, our study compares the safety and effectiveness of lead-in parenteral anticoagulation to lead-in apixaban or rivaroxaban in patients who received apixaban or rivaroxaban for VTE treatment.

Methods: A multi-center retrospective cohort study included adult patients (aged ≥ 18 years) admitted to the hospital with acute VTE and treated with either apixaban or rivaroxaban.
