The patient population with the need for oral anticoagulation to reduce stroke risk associated with atrial fibrillation (AF) and dual antiplatelet therapy to prevent stent thrombosis and myocardial infarction after percutaneous coronary intervention is increasing. However, patients treated with a triple therapy consisting of oral anticoagulation, aspirin, and a P2Y12 inhibitor have been demonstrated to be at high bleeding risk. The best combination of these agents and the duration of the different therapies are still uncertain...

Venous thromboembolism (VTE) is a frequent complication of cancer associated with morbidity, mortality, increased hospitalizations and higher health care costs. Cancer patients at increased risk for VTE can be identified using a validated risk assessment score, and the incidence of VTE can be reduced in high-risk settings using anticoagulation. Rivaroxaban is a potent, oral, direct, factor Xa inhibitor approved for the prevention and treatment of thromboembolic events, including VTE. CASSINI is a double-blind, randomized, parallel-group, multicentre study comparing rivaroxaban with placebo in adult ambulatory patients with various cancers who are initiating systemic cancer therapy and are at high risk of VTE (Khorana score ≥ 2)...

BACKGROUND AND AIMS: Budd-Chiari syndrome (BCS) is treated with anticoagulation therapy, transjugular intrahepatic portosystemic shunt (TIPS), angioplasty, and liver transplantation. TIPS is not always technically feasible, due to the complete hepatic venous thrombosis. Direct intrahepatic portosystemic shunt (DIPS) is an alternative method for decompression of portal hypertension. This is a retrospective, single-center study aiming to evaluate the outcome of ultrasound (US)-guided DIPS in patients with BCS...

Platelets, anucleated megakaryocyte-derived cells, play a major role in hemostasis and arterial thrombosis. While protein kinase Casein Kinase 2 (CK2) is readily detected in megakaryocytes and platelets, the impact of CK2-dependent signaling on megakaryocyte/platelet (patho-) physiology has remained elusive. The present study explored the impact of the CK2 regulatory β-subunit on platelet biogenesis and activation. Megakaryocyte/platelet-specific genetic deletion of CK2β (ck2β(-/-) ) in mice resulted in a significant macrothrombocytopenia and an increased extramedullar megakaryopoiesis with enhanced proportion of premature platelets...

Given that platelet hyperactivity is known to give rise to thrombotic disorders, new and/or novel antiplatelet therapies are constantly being developed to add to, or to complement the current arsenal of agents. To this end, adenosine diphosphate (ADP) is an important platelet activator that acts by binding to the G-protein coupled P2Y1 and P2Y12 receptors. Although the contribution of the P2Y12 receptor to the genesis of thrombosis is well established, the parenteral arsenal of drugs targeting this receptor in clinical use is limited to cangrelor...

INTRODUCTION: The purpose of this study was twofold:1) to investigate whether edoxaban significantly decreases the rate of venous thromboembolism (VTE) following closed-wedge high tibial osteotomy (CWHTO), in terms of phlebographic event, and 2) to determine whether edoxaban is safe or increases the rate of hemorrhagic complications.We hypothesized that edoxaban would decrease the incidence of VTE and would not increase the rate of hemorrhagic complications. MATERIALS AND METHODS: We randomly enrolled 60 patients undergoing CWHTO...

BACKGROUND: The current standard-of-care treatments for pediatric venous thromboembolism (VTE) have limitations. Dabigatran etexilate (DE), a direct thrombin inhibitor, may offer an alternative therapeutic option. OBJECTIVES: To assess the pharmacokinetics (PK), pharmacodynamics (PD), safety and tolerability of DE oral liquid formulation (OLF) in pediatric patients with VTE. PATIENTS/METHODS: Patients who had completed planned treatment with low-molecular-weight heparin or oral anticoagulants for VTE were enrolled in two age groups (2-<12 and 1-<2 years) and received DE OLF based on an age- and weight-adjusted nomogram...

INTRODUCTION: Oxidative stress and platelet integrin α2bβ3 plays important role in the process of hemostasis and thrombosis. We hypothesized that device-induced patient specific oxidative stress and integrin α2bβ3 shedding may be linked to major bleeding complication (MBC) in heart failure (HF) patients supported by continuous flow left ventricular assist devices (CF-LVADs). MATERIALS AND METHODS: We recruited 47patients implanted with CF-LVADs and 15 healthy volunteers...

REVIEW
Annemarie E Fogerty
Thrombotic complications in pregnancy represent a major cause of morbidity and mortality. Pregnancy is a primary hypercoagulable state due to enhanced production of clotting factors, a decrease in protein S activity, and inhibition of fibrinolysis. These physiologic changes will yield a collective rate of venous thromboembolism (VTE) of about 1-2 in 1000 pregnancies for the general obstetric population, which represents a five- to tenfold increased risk in pregnancy compared to age-matched non-pregnant peers...

Whether primary prophylaxis should be prescribed in individuals with antiphospholipid antibodies (aPL) remains controversial due to the lack of relevant evidence-based data. Indeed, it is unclear whether the benefit of LDA outweighs the risk of major bleeding associated LDA in a low-risk population. On the contrary, stratification of aPL-positive subjects according to their aPL profile (combination, isotype and titer), presence of other concomitant risk factors for thrombosis and coexistence of an underling autoimmune disease is essential to decide whether primary prophylactic therapy should be prescribed...

Introduction or background: Anticoagulant therapy is mainly used to prevent patients from suffering coronary and systemic thromboembolism after stenting. Many studies have been done to formulate an optimized regimen of a post-PCI or long-time anticoagulant therapy. Recent advances in the selection and duration of anticoagulant agents will be conducive to the management of patients who are considered to need anticoagulant therapy after stenting. Sources of data: Key recent published literature, including international guidelines and relevant reviews...

This article is a review of the literature, related to the problem of recurrence of venous thromboembolic complications and the possibilities of their secondary prevention. The problems of determining the rational duration of anticoagulant therapy on the basis of an individual assessment of its benefit and risk are considered. The information on modern prognostic models allowing quantitative assessment of the probability of hemorrhagic and thrombotic events occurrence is presented (Vienna prediction model, DASH, HAS-BLED, stratification according to ACCP 2016)...
