Ischemic Stroke in Cancer: Mechanisms, Biomarkers, and Implications for Treatment
Semin Thromb Hemost DOI: 10.1055/s-0043-1771270Ischemic stroke is an important cause of morbidity and mortality in cancer patients. The underlying mechanisms linking cancer and stroke are not completely understood. Long-standing and more recent evidence suggests that cancer-associated prothrombotic states, along with treatment-related vascular toxicity, such as with chemotherapy and immunotherapy, contribute to an increased risk of ischemic stroke in cancer patients. Novel biomarkers, including coagulation, platelet and endothelial markers, cell-free DNA, and extracellular vesicles are being investigated for their potentia...

Prevention of Venous Thromboembolism in Medical Patients with Thrombocytopenia or with Platelet Dysfunction: The Last 10 Years
Semin Thromb Hemost DOI: 10.1055/s-0043-1769013Current guideline recommendations for primary prophylaxis of venous thromboembolism (VTE) are based on randomized clinical trials that usually exclude subjects at a potentially high risk of bleeding complications. For this reason, no specific guideline is available for thromboprophylaxis in hospitalized patients with thrombocytopenia and/or platelet dysfunction. However, except in patients with absolute contraindications to anticoagulant drugs, antithrombotic prophylaxis should always be considered, for example, in hospitalized cancer patients with thrombocytopenia, especially...

Viscoelastic Testing in the Clinical Management of Subarachnoid Hemorrhage and Intracerebral Hemorrhage
In conclusion, viscoelastic testing suggests hypercoagulation following SAH and ICH. Further investigation of the predictive value of increased clot firmness in SAH seems relevant. In ICH, the prediction of hematoma expansion and ICH as a complication to thrombolysis might be clinically relevant.

Direct Oral Anticoagulants Plasma Levels Measurement: Clinical Usefulness from Trials and Real-World Data
Semin Thromb Hemost 2021; 47: 150-160 DOI: 10.1055/s-0041-1723770Measurement of direct oral anticoagulants (DOACs) activity is not routinely necessary. Indeed, evaluation of DOACs plasmatic concentration is discouraged for the majority of patients, due to the lack of outcome data supporting this approach. Nevertheless, DOAC measurements may be useful in emergency situations such as serious bleeding events, need for urgent invasive procedures, and acute ischemic stroke or in managing anticoagulation in “special populations” not adequately studied in clinical trials, for example the very elderly or those at the extremes ...

Sulodexide versus Control and the Risk of Thrombotic and Hemorrhagic Events: Meta-Analysis of Randomized Trials
Semin Thromb Hemost DOI: 10.1055/s-0040-1716874Thrombotic cardiovascular disease (myocardial infarction [MI], stroke, and venous thromboembolism [VTE]) remains a major cause of death and disability. Sulodexide is an oral glycosaminoglycan containing heparan sulfate and dermatan sulfate. We conducted a systematic review and meta-analysis to determine the cardiovascular efficacy, and safety of sulodexide versus control in randomized controlled trials (RCTs). We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for RCTs reporting cardiovascular outcomes in patients receiving sulodexide versus co...

Heparin Bridging Therapy for Patients on Chronic Oral Anticoagulants in Periprocedural Settings
Semin Thromb Hemost DOI: 10.1055/s-0039-1696945Interruption of chronic anticoagulation due to the bleeding risk associated with an elective procedure may also lead to an elevated risk of thromboembolism. Periprocedural bridging with either unfractionated heparin or low-molecular weight heparin had been the mainstay of therapy for many patients receiving chronic warfarin treatment based on an estimation of a patient's thromboembolic risk. However, recent results from cohort studies and placebo-controlled randomized trials in the periprocedural use of heparin bridging for warfarin-treated patients reveal a consistent two- to...

Feeling the Force: Measurements of Platelet Contraction and Their Diagnostic Implications
Semin Thromb Hemost DOI: 10.1055/s-0038-1676315In addition to the classical biological and biochemical framework, blood clots can also be considered as active biomaterials composed of dynamically contracting platelets, nascent polymeric fibrin that functions as a matrix scaffold, and entrapped blood cells. As platelets sense, rearrange, and apply forces to the surrounding microenvironment, they dramatically change the material properties of the nascent clot, increasing its stiffness by an order of magnitude. Hence, the mechanical properties of blood clots are intricately tied to the forces applied by individual platelets. ...

Atrial Fibrillation and Malignancy: The Clinical Performance of Non –Vitamin K Oral Anticoagulants—A Systematic Review
Semin Thromb Hemost DOI: 10.1055/s-0038-1661386Atrial fibrillation (AF) is commonly diagnosed in the setting of active cancer. Because of an increased risk of either thromboembolic events or bleeding, the decision to initiate therapeutic anticoagulation in patients with active cancer can be challenging. Moreover, little is still known about the optimal anticoagulation therapy in the setting of AF and cancer, and no guidelines are as yet available. Considering that nonvitamin K antagonist oral anticoagulants (NOACs) are recommended as alternatives to vitamin K antagonists for stroke prevention in AF patients with CHA2DS2-VA...

Hemostasis in the Very Young
Semin Thromb Hemost DOI: 10.1055/s-0038-1660852Hemostasis is a dynamic process that starts in utero. The coagulation system evolves with age, as evidenced by marked physiological differences in the concentration of the majority of hemostatic proteins in early life compared with adulthood. This concept, known as “developmental hemostasis,” has important biological and clinical implications. Overall, impaired platelet function, along with physiologically reduced levels of vitamin K–dependent and contact coagulation factors, may cause poorer clot firmness even in healthy neonates. However, increased activity of von Will...

Causes of Death in Patients with Venous Thromboembolism Anticoagulated with Direct Oral Anticoagulants: A Systematic Review and Meta-Analysis
Semin Thromb Hemost DOI: 10.1055/s-0038-1642644Death is more frequent than nonfatal recurrent venous thromboembolism (VTE) and major bleeding after acute VTE. The analysis of the causes of death is fundamental to explore new strategies to reduce mortality rates in these patients. The authors performed a meta-analysis to analyze mortality and independently adjudicated causes of death in anticoagulated patients due to VTE, and to evaluate potential differences between different anticoagulant schemes. They searched MEDLINE and CENTRAL, from January 1, 2000, to January 31, 2017, and performed additional searches in Web sites o...

Direct Oral Anticoagulants and the Paradigm Shift in the Management of Venous Thromboembolism
Semin Thromb Hemost DOI: 10.1055/s-0038-1637750The advent of direct oral anticoagulants (DOACs) has revolutionized anticoagulation management in both stroke prevention and venous thromboembolism (VTE) treatment/prevention. Clinical trials and secondary real-world data have shown that DOACs have similar efficacy and, in some cases, improved bleeding safety profiles compared with vitamin K antagonists. Together with benefits of patient convenience, this has shifted the risk–benefit ratio toward long-term anticoagulation. However, current VTE risk assessment models are based on vitamin K antagonists and do not take into acc...
