Failure to test for pulmonary embolism (PE) can be a lethal mistake, but PE and produces symptoms similar to many other diseases. Overtesting for PE has negative consequences. ⋯ A thoughtful algorithm for PE exclusion and diagnosis requires pretest probability assessment in all patients, followed by selective use of clinical criteria, the quantitative D-dimer, and pulmonary vascular imaging.

ReviewCurrent evidence of oral anticoagulant reversal: A systematic review.
Approximately 4-6% of patients treated with oral anticoagulants (OAC) will suffer from major hemorrhage or be in need of urgent surgery necessitating anticoagulant reversal therapy. Several new oral anticoagulants and reversal agents have been introduced that make it difficult for physicians to stay updated on the current evidence of reversal management. This study aims to review the recent literature on oral anticoagulation reversal therapy and to present the current evidence in an easily approachable manner. ⋯ This review supports the use of PCC for VKA reversal, specifically for 4F-PCC over FFP for laboratory reversal. There are no studies on clinical efficacy of non-specific agents for DOAC reversal and the evidence for laboratory reversal is not consistent.

ReviewNonvitamin K-dependent oral anticoagulants (NOACs) in chronic kidney disease patients with atrial fibrillation.
Atrial fibrillation (AF) represents the most common arrhythmia in patients with chronic kidney disease (CKD). As in the general population, in CKD patients AF is associated with an increased risk of thromboembolism and stroke. However, CKD patients, especially those on renal replacement therapy (RRT), also exhibit an increased risk of bleeding, especially from the gastrointestinal tract. ⋯ Hence, they are currently recommended for patients with atrial fibrillation at risk for stroke. However, NOACs metabolism is largely dependent on the kidneys for elimination and little is known in patients with creatinine clearance <25ml/min who were excluded from all pivotal phase 3 NOACs trials. This review focuses on the current pharmacokinetic, observational, and prospective data on NOACs in patients with moderate to advanced chronic kidney disease (creatinine clearance 15-49ml/min) and those on dialysis.

Review Meta Analysis Comparative StudyComparison of intravenous versus topical tranexamic acid in primary total hip and knee arthroplasty: An updated meta-analysis.
The appropriate route for administering tranexamic acid in primary total hip (THA) and knee arthroplasty (TKA) remains controversial. The purpose of this meta-analysis was to compare the efficacy and safety of topical or intravenous tranexamic acid. ⋯ The available evidence indicates similar transfusion requirements and safety for topical and intravenous tranexamic acid in THA and TKA. However, intravenous injection seems to be associated with a smaller maximum drop in hemoglobin.
