Thrombin activates platelets via proteolytic cleavage of protease-activated receptors (PARs) 1 and 4. The two PARs have distinct but complementary roles. The mechanisms responsible for PAR1 activation by thrombin have been extensively studied. However, much less is known regarding thrombin activation of PAR4, especially the potential involvement of regions of PAR4 other than the N-terminal, which is bound to the catalytic site of thrombin. We have studied PAR4 in S. cerevisiae strain MMY12, an expression system in which the GPCR receptors are connected to a Lac Z reporter gene resulting in increased β-galactosidase activity...

BACKGROUND: The ROCKET AF study evaluated once-daily rivaroxaban versus dose-adjusted warfarin for the prevention of stroke and systemic embolism in patients with atrial fibrillation (AF). In this analysis, we compared rivaroxaban with warfarin in patients with AF from China, East Asia, and the rest of the world (ROW). METHODS AND RESULTS: We assessed baseline demographics and interaction of treatment effects of rivaroxaban versus warfarin among patients from mainland China, other East Asian countries, and ROW...

BACKGROUND: Clotting parameters are informative of overall haematological healthiness of an individual. Particularly, clotting parameters can be used as a measure of the degree of pathology of the coagulation system. Thromboelastography (TEG) is a well-known technique that is an important point-of-care method, as well as research method. Scanning electron microscopy (SEM) is a novel research method, but with possible clinical application. However, there are no clear standardized guidelines for TEG and SEM result interpretation...

BACKGROUND: Computed tomographic pulmonary angiography (CTPA) has simplified the diagnostic approach to patients with clinically suspected pulmonary embolism (PE), but alternative imaging tests are still advocated. We aimed to systematically assess the diagnostic accuracy of magnetic resonance imaging (MRI) for PE diagnosis. METHODS: Studies evaluating the diagnostic accuracy of MRI for the diagnosis of PE were systematically searched in the PubMed and EMBASE databases (up to May 2016)...

INTRODUCTION: Patients with cancer are at increased risk of thrombosis, particularly those with central venous catheter (CVC) placement, which may predispose to the development of upper extremity deep vein thrombosis (UEDVT). Standard treatment includes low molecular weight heparin (LMWH) or LMWH bridged to warfarin. The direct oral anticoagulants (DOACs) have become standard of care for uncomplicated venous thromboembolism (VTE), but research in patients with cancer is ongoing. OBJECTIVES: To assess rivaroxaban monotherapy in patients with cancer who develop UEDVT due to CVC for preservation of line function, and safety outcomes of VTE recurrence, bleeding risk and death...

BACKGROUND: Cardiac surgery may cause a serious coagulopathy leading to increased risk of bleeding and transfusion demands. Blood bank products are commonly first line haemostatic intervention, but has been associated with hazardous side effect. Coagulation factor concentrates may be a more efficient, predictable, and potentially a safer treatment, although prospective clinical trials are needed to further explore these hypotheses. This study investigated the haemostatic potential of ex vivo supplementation of coagulation factor concentrates versus blood bank products on blood samples drawn from patients undergoing cardiac surgery...

BACKGROUND: The optimal long-term strategy for preventing recurrent venous thromboembolism (VTE) in patients with deep-vein thrombosis (DVT) is uncertain. METHODS: In 620 consecutive outpatients with a first proximal DVT who had completed at least three months of anticoagulation (unprovoked in 483, associated with minor risk factors in 137), the ultrasound presence of residual vein thrombosis (RVT) was assessed and defined as an incompressibility of at least 4mm...

OBJECTIVES: Circulating leukocyte-derived microparticles act as proinflammatory mediators that reflect vascular inflammation. In this study, we examined the hypothesis that the quantity of leukocyte-derived microparticles is increased in patients with ischemic cerebrovascular diseases, and investigated utility of various phenotypes of leukocyte-derived microparticles as specific biomarkers of vascular inflammation injury. Additionally we focused on identifying leukocyte-derived microparticles that may be correlated with stroke severity in acute ischemic stroke patients...

BACKGROUND: Venous thromboembolism (Wickham et al., 2012 [1]) is a leading cause of morbidity and mortality among patients with cancer; however, primary thromboprophylaxis is not routinely recommended. We performed a systematic review and meta-analysis of randomized control trials (RCTs) to measure the impact of primary VTE prevention and its effect on mortality among patients with lung cancer. METHODS: With assistance from a master librarian, we searched Ovid, Scopus, DARE, CINAHL, MEDLINE, EMBASE, EBM reviews-Cochrane database of systematic reviews, EBM reviews-ACP journal, and EBM Reviews-Databases for relevant studies following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Direct oral anticoagulants (DOACs) are at least as efficacious as conventional anticoagulation therapy for the initial and long-term treatment of cancer patients with venous thromboembolism (VTE). Whether DOACs are non-inferior to low-molecular-weight heparin for the management of cancer patients with VTE is under investigation. In addition, the efficacy of DOACs for the treatment of cancer patients with arterial thrombosis (e.g., ischemic stroke) remains unclear. Herein, we report on two cancer patients admitted to our hospital with Stage IV gastric adenocarcinoma who were being treated with DOACs due to a history of VTE and had developed their first ever ischemic stroke, which was diagnosed due to cancer-related hypercoagulation...

BACKGROUND: β-thromboglobulins are derived from the cleavage of the CXC chemokine platelet basic protein and are released in high concentrations by activated platelets. Platelet-derived β-thromboglobulins (βTG) share 70% homology with platelet factor 4 (PF4), another CXC chemokine released by activated platelets. PF4 modulates coagulation by inhibiting heparin-antithrombin interactions, promoting protein C activation, and attenuating the activity of activated protein C. In contrast, the effect of βTG on coagulation is unknown...

BACKGROUND: The recanalization rate in patients with deep venous thrombosis (DVT) of the legs treated with the direct oral anticoagulants (DOAC) is unknown. METHODS: In an Italian cohort, we investigated the rate of residual vein thrombosis (RVT) after three and/or six months in 352 patients with proximal DVT who had been treated with the DOACs as a stand-alone therapy or lead-in parenteral anticoagulants, and compared it to that recorded in a historical cohort of 1094 patients in which vitamin K antagonists (VKAs) had been employed...

BACKGROUND AND AIMS: Cardiovascular diseases of thrombotic origin are related to high mortality and standard therapeutic agent used in this case is acetylsalicylic acid (ASA), but serious adverse events may occur. However, recent data has suggested the plant Campomanesia xanthocarpa has antiplatelet activity and could be a viable alternative. In this study we investigated the effects of the encapsulated powder of this plant in human platelet aggregation. METHODS: 23 healthy subjects were randomly divided into three groups: (1) ASA (100mg), (2) C...

BACKGROUND: Several characteristics such as demographics, pre-existing conditions, surgical procedure, perioperative coagulopathy may predispose children undergoing cardiopulmonary bypass (CPB) to bleeding complications. As yet, studies on risk factors for postoperative bleeding have brought mixed results. The purpose of our study was therefore to retrospectively evaluate the parameters able to predict postoperative bleeding in a group of consecutive children undergoing cardiac surgery involving CPB...

BACKGROUND: Point-of-care testing (POCT) is regularly used to assess haemostasis in various clinical settings. The impact of rivaroxaban on those POCT is still elusive. We aimed to study the effects of rivaroxaban on most commonly used POCT assays. METHODS: Blood samples were taken before, 3h, and 24h after administration of 20mg rivaroxaban to 20 healthy volunteers as part of a prospective, multicenter validation study (clinicaltrials.govNCT01710267). Blood samples were analysed with thromboelastometry (ROTEM®), two platelet function assays (INNOVANCE® PFA-200 and Multiplate®), and the CoaguChek® XS...
