PURPOSE: The pivotal trials for stroke prevention in non-valvular atrial fibrillation (NVAF) compared rivaroxaban, dabigatran, and apixaban with warfarin, as did most claims-based studies. Comparisons with phenprocoumon, the most frequently used vitamin K antagonist (VKA) in Germany, are scarce. METHODS: Risk of bleeding, ischemic stroke, and all-cause mortality in patients with NVAF were analyzed using data for 2010 to 2014 from a large German claims database. New users of oral anticoagulants from January 2012 to December 2013 were included and observed over 1 year...

Dabigatran, a new oral anticoagulant, is a direct thrombin inhibitor used as an alternative to warfarin to reduce the risk of stroke and systemic embolism with nonvalvular atrial fibrillation. We report a case of a man who resumed dabigatran after 6 weeks of prior therapy and began experiencing hematuria with worsening kidney function. Renal biopsy with immunofluorescence and electron microscopy showed mesangial deposits consistent with immunoglobulin A nephropathy. With discontinuation of dabigatran and addition of methylprednisolone, the gross hematuria cleared and urine output improved...

Patients exposed to long acting anticoagulant rodenticides (LAARs) are typically administered large amounts of oral vitamin K1 (VK1) to counteract life-threatening anti-coagulant effects. While VK1 treatment effectively prevents mortality, additional methods are needed to reduce the long duration of VK1 treatment which can last for months at high expense. We developed a model of brodifacoum (BDF) poisoning, one of the most potent LAARs, in adult male New Zealand White (NZW) rabbits. The LD50 for oral BDF was determined to be 192 μg/kg, similar to that calculated for adult rats...

Cardiac embolism continues to be a leading etiology of ischemic strokes worldwide. Although pathologies that result in cardioembolism have not changed over the past decade, there have been significant advances in the treatment and stroke prevention methods for these conditions. Atrial fibrillation remains the prototypical cause of cardioembolic strokes. The availability of new long-term monitoring devices for atrial fibrillation detection such as insertable cardiac monitors has allowed accurate detection of this leading cause of cardioembolism...

Atrial fibrillation is the most frequent cardiac arrhythmia, affecting up to 13% of people aged>80 years, and is responsible for 15-20% of all ischaemic strokes. Left atrial appendage occlusion devices have been developed as an alternative approach to reduce the risk of stroke in patients for whom oral anticoagulation is contraindicated. The procedure can be technically demanding, and obtaining a complete left atrial appendage occlusion can be challenging. These observations have emphasized the importance of preprocedural planning, to optimize the accuracy and safety of the procedure...

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is associated with the development of atrial fibrillation (AF), and may complicate treatment of AF. We examined the association between COPD and symptoms, quality of life (QoL), treatment and outcomes among patients with AF. METHODS: We compared patients with and without a diagnosis of COPD in the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation, a prospective registry that enrolled outpatients with AF not secondary to reversible causes, from both academic and community settings...

Introduction - Expanding indications have resulted in an increasing number of patients taking novel oral anticoagulants, posing a major treatment dilemma in acute ischemic stroke. Case presentation - We present a successful intravenous thrombolysis in a dabigatran-treated patient with acute ischemic stroke after the administration of idarucizumab. Discussion - According to current guidelines, systemic thrombolysis is contraindicated under treatment with novel oral anticoagulants (taken within 48 hours). In this scenario, idarucizumab offers a solution by reversing the anticoagulant effect of dabigatran...

PURPOSE: Algorithms to define current exposure to warfarin using administrative data may be imprecise. Study objectives were to characterize dispensation patterns, to measure gaps between expected and observed refill dates for warfarin and direct oral anticoagulants (DOACs). METHODS: Retrospective cohort study using administrative health care databases of the Régie de l'assurance-maladie du Québec. We identified every dispensation of warfarin, dabigatran, rivaroxaban, or apixaban for patients with AF initiating oral anticoagulants between 2010 and 2015...

The aim of this study was to evaluate the adverse drug reaction (ADR) incidence rate and new signals thereof for classic compared with new anticoagulants in real-life ambulatory settings. The authors performed an observational cross-sectional study in two cohorts of surveyed patients treated with vitamin K antagonists (VKAs; acenocoumarol or warfarin) or nonvitamin K antagonist oral anticoagulants (NOACs; apixaban, edoxaban, rivaroxaban, dabigatran etexilate). Descriptive, clinical, and ADRs data were reported and analyzed through a bivariate analysis (odds ratio [OR]) to compare the ADRs incidence rate and an adaptation of Bayesian methodology (false discovery rate [FDR] < 0...

Dabigatran etexilate mesylate is a direct thrombin inhibitor used for reducing the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation. Dabigatran belongs to a new generation of oral agents for anticoagulation - the direct oral anticoagulants (DOACs). The DOACs also include the factor Xa inhibitors rivaroxaban, apixaban, and edoxaban. In the case of major or life-threatening bleeding and/or the need for emergent invasive procedures, a reversal agent is needed if a patient is taking one of these medications...

Regenerative therapies with platelets have been widely used in medicine over the past two decades as a means to speed revascularization to damaged/defective tissues. Within the oral cavity, the sinus is one of the least vascularized areas with healing times typically increased to augment lost or missing bone. As a result, attempts have been proposed to combine platelet concentrates with various biomaterials to accelerate new blood flow to these tissues and ultimately facilitate new bone regeneration. While platelet-rich plasma (PRP) was introduced as a first-generation platelet concentrate, more recently platelet-rich fibrin (PRF) has been developed with anticoagulant removal from centrifugation protocols...

OBJECTIVES: Catheter-related right atrial thrombosis (CRAT) is an underreported but potentially life-threatening complication associated with the use of tunneled-cuffed catheters among hemodialysis (HD) patients. Because little is known about the evidence-based guidelines for the optimal management of CRAT among HD patients, this article reports findings based on 20 patients diagnosed with CRAT after catheter replacement and anticoagulation treatment. METHODS: The article retrospectively reviews the hospital records of 20 HD patients treated in the West China Hospital with diagnosis of CRAT from March 2013 to May 2016...

INTRODUCTION: New oral anticoagulants are non-inferior compared with warfarin regarding stroke prevention in atrial fibrillation, with similar or decreased risk of bleeding. However, it is unclear whether high TTR warfarin is as effective and safe as NOACs. Our objective was to investigate efficacy and safety of apixaban, dabigatran or rivaroxaban compared with warfarin in clinical practice. MATERIALS AND METHODS: Nationwide retrospective cohort study based on Swedish quality registries...

Atrial fibrillation and atrial flutter (AF/AFL) are associated with an increased risk of stroke and systemic embolism. However, many patients are not started on guideline-recommended oral anticoagulation (OAC). We determined factors associated with initiation of OAC in eligible patients presenting to emergency departments. This retrospective cohort included patients with electrocardiogram (ECG)-documented AF/AFL presenting to 4 urban emergency departments in 2015. Presenting diagnoses, admission status, and comorbidities were determined by chart review...
