Evidence-Based Practical Guidance for the Antithrombotic Management in Patients With Coronavirus Disease (COVID-19) in 2020.
This practical guidance, endorsed by the Brazilian Society of Thrombosis and Hemostasis and The Brazilian Society of Angiology and Vascular Surgery, the International Union of Angiology and the European Venous Forum, aims to provide physicians with clear guidance, based on current best evidence-based data, on clinical strategies to manage antithrombotic strategies in patients with coronavirus disease 2019.

COVID-19 Associated Coagulopathy and Thrombotic Complications.
The SARS-CoV-2 virus caused a global pandemic within weeks, causing hundreds of thousands of people infected. Many patients with severe COVID-19 present with coagulation abnormalities, including increase D-dimers and fibrinogen. This coagulopathy is associated with an increased risk of death. ⋯ A better understanding of COVID-19 pathophysiology, in particular hemostatic disorders, will help to choose appropriate treatment strategies. A rigorous thrombotic risk assessment and the implementation of a suitable anticoagulation strategy are required. We review here the characteristics of COVID-19 coagulation laboratory findings in affected patients, the incidence of thromboembolic events and their specificities, and potential therapeutic interventions.

Anti-Factor Xa Levels in Low-weight Surgical Patients Receiving Enoxaparin for Venous Thromboembolism Prophylaxis: A Prospective Cohort Study.
Enoxaparin is indicated for thromboprophylaxis in non-orthopedic surgical patients at a fixed dose of 40 mg daily. According to the US Food and Drug Administration's enoxaparin prescribing information, this dose exposes low-weight patients (males < 57 kg, females < 45 kg) to a higher risk of bleeding. This study aimed to determine the rate of achieving a prophylactic peak anti-factor Xa (AFXa) level in low-weight surgical patients using enoxaparin 30 mg daily. ⋯ Four venous thromboembolism events (3.3%) were observed in patients with sub-prophylactic peak AFXa levels (9.7%). Two-thirds of low-weight surgical patients achieved a prophylactic peak AFXa level using daily enoxaparin 30 mg. This dose is likely to provide adequate thromboprophylaxis in low-weight females.
