Development of a Plasma-Based Assay to Measure the Susceptibility of Factor V to Inhibition by the C-Terminus of TFPI α.

CONCLUSION:  We have developed and validated an assay that measures the susceptibility of plasma FV to the TFPIα C-terminus. Once automated, this assay may be used to test whether the TFPIr correlates with thrombosis or bleeding risk in population studies. PMID: 31705518 [PubMed - as supplied by publisher]

Enoxaparin 40 mg daily is often associated with subprophylactic peak anti-Xa levels in surgical oncology patients. Dose adjustment based on anti-Xa levels resulted in a lower rate of in-hospital venous thromboembolism without increased risk of bleeding.

Authors: Iorga RA, Bratu OG, Marcu RD, Constantin T, Mischianu DLD, Socea B, Gaman MA, Diaconu CC Abstract Patients with cancer-associated venous thromboembolism (VTE) represent a real challenge in clinical practice. Patients with cancer have a greater risk both of VTE and bleeding. There are only a few studies regarding the therapeutic approach of VTE in patients with cancer, especially after cancer surgery, and on thromboprophylaxis during chemotherapy. Many of the anticoagulation therapy recommendations for cancer patients are extrapolated from trials that are not conducted in cancer cohorts. It is essential to ...

ConclusionsThe TRREMS procedure significantly improved evacuation disorders in this study. Appropriate selection of patients is key for the success of this approach. Anismus even if previously treated with biofeedback, was the main predictive factor of unsuccessful treatment.

Conclusion Compared with heparin plus GPI or bivalirudin plus GPI, bivalirudin monotherapy provides similar protection from ischemic events with less major bleeding at 30 days among patients with NSTE-ACS and positive biomarkers.

Congenital fibrinogen disorders are rare inherited bleeding disorders characterized by bleeding or thrombosis. They can be divided into type I deficiencies or quantitative defects (afibrinogenemia and hypofibrinogenemia) which are defined when those with fibrinogen levels are below 1.5  g/L and type II deficiencies or qualitative defects (dysfibrinogenemia and hypodysfibrinogenemia) [1]. The estimated prevalence of afibrinogenemia is about 1:1,000,000. Although dysfibrinogenemia and hypofibrinogenemia are more frequent, their accurate prevalence remains unknown as most cases are asymptomatic [1,2].

Studies have indicated differences between Asians and Whites in their propensity for stroke, coronary artery disease, heart failure, bleeding and thrombosis. We investigated whether Asian-Americans on durable left ventricular assist devices (LVADs) exhibit differential morbidity and mortality when compared to Whites.

CONCLUSION:  We have created a large individual patient database of bivalirudin versus heparin RCTs in patients with AMI undergoing PCI. This endeavor may help identify the optimal periprocedural anticoagulation regimen for patient groups with different relative risks of adverse ischemic versus bleeding events, including those with ST-segment and non-ST-segment elevation MI, radial versus femoral access, use of a prolonged bivalirudin infusion or glycoprotein inhibitors, and others. Adherence to standardized techniques and rigorous validation processes should increase confidence in the accuracy and robustness of the r...

AbstractThe use of intramuscular injections is widely recommended to be avoided in patients who are prescribed anticoagulant agents, both oral and parenteral due to concerns of haematoma. Benzathine penicillin G (BPG), administered via intramuscular injection, is a vital treatment component for patients with rheumatic heart disease. BPG must be administered long term (for at least a decade) as part of treatment and alternative options to intramuscular injection are currently limited. Many of these patients with rheumatic heart disease will also require long term or lifelong anticoagulation. Our retrospective, single centre...

Authors: Stein BL, Martin K Abstract Thrombotic and hemorrhagic complications are prevalent in patients with essential thrombocythemia, polycythemia vera, and myelofibrosis. Given the impact on morbidity and mortality, reducing the risk of thrombosis and/or hemorrhage is a major therapeutic goal. Historically, patients have been risk stratified on the basis of traditional factors, such as advanced age and thrombosis history. However, multiple factors contribute to the thrombotic tendency, including gender, mutational profile, inflammatory stress, and abnormal cell adhesion. Management includes cardiovascular risk r...
