ReviewTACTIC: Trans-Agency Consortium for Trauma-Induced Coagulopathy.
Trauma-induced coagulopathy (TIC) includes heterogeneous coagulopathic syndromes with different underlying causes, and treatment is challenged by limited diagnostic tests to discriminate between these entities in the acute setting. We provide an overview of progress in understanding the mechanisms of TIC and the context for several of the hypotheses that will be tested in 'TACTIC'. ⋯ We do anticipate that 'early translation' of promising results will occur. Functions anticipated at this early translational level include: (i) basic science groundwork for future therapeutic candidates; (ii) development of acute coagulopathy scoring systems; (iii) coagulation factor composition-based computational analysis; (iv) characterization of novel analytes including tissue factor, polyphosphates, histones, meizothrombin and α-thrombin-antithrombin complexes, factor XIa, platelet and endothelial markers of activation, signatures of protein C activation and fibrinolysis markers; and (v) assessment of viscoelastic tests and new point-of-care methods.

ReviewTreatment of acute ischemic stroke: from fibrinolysis to neurointervention.
Thrombolytic therapy with intravenous recombinant tissue plasminogen activator is well established as a beneficial treatment for patients presenting with acute ischemic stroke (AIS). The odds of a favorable clinical outcome (living independently) increase as the time between stroke onset and treatment with IV thrombolysis decreases. ⋯ Alternative options include new and emerging endovascular therapies that have recently proven effectiveness at restoring cerebral blood flow to the ischemic brain parenchyma. This review article will briefly outline some of the key evidence for intravenous thrombolysis as well as endovascular therapy for AIS.

ReviewExtracorporeal life support: the precarious balance of hemostasis.
Extracorporeal life support is by far the most extraordinary and complex form of extracorporeal technology used in the practice of critical care medicine. It is used to support critically ill patient who suffer acute respiratory or cardiac failure unresponsive to conventional support. ⋯ The management of a patient on ECLS is the same as for any critically ill patient with the added need for anticoagulation to maintain patency of the extracorporeal circuit without causing bleeding within the patient and thrombosis within the circuitry or the patient. This is the precarious balance of hemostasis during ECLS.

ReviewAcquired thrombotic thrombocytopenic purpura: new therapeutic options and their optimal use.
Advances in our understanding of the pathophysiology of both congenital and acquired thrombotic thrombocytopenic purpura (TTP) have led to both an increased understanding of the disease and novel approaches to therapy. The efficacy of rituximab in acquired TTP has led to consideration of rituximab as a prophylactic therapy to prevent relapse of TTP. ⋯ Additionally, a recombinant ADAMTS13 protease has been developed which may be an important therapeutic option for both congenital and acquired TTP. The development of these new therapeutic options for patients diagnosed with TTP has increased the importance of conducting prospective, randomized studies with these agents to both confirm their efficacy and more importantly understand their most appropriate role in the treatment of patients with TTP.

ReviewNew strategies for effective treatment of vitamin K antagonist-associated bleeding.
Vitamin K antagonists have been used as oral anticoagulants in the treatment and prevention of thromboembolic events for over half a century. Although vitamin K antagonists are effective in the management of thromboembolic events, the need for routine monitoring and the associated risk of bleeding has resulted in the development and licensing of direct oral anticoagulants for specific clinical indications. ⋯ Several options for the reversal of vitamin K antagonist exist, including vitamin K, prothrombin complex concentrates and plasma. In this manuscript, we review current evidence and provide physicians with treatment strategies for more effective management of vitamin K antagonist-associated bleeding.
