Intermediate versus standard-dose prophylactic anticoagulation and statin therapy versus placebo in critically-ill patients with COVID-19: Rationale and design of the INSPIRATION/INSPIRATION-S studies.
Microvascular and macrovascular thrombotic events are among the hallmarks of coronavirus disease 2019 (COVID-19). Furthermore, the exuberant immune response is considered an important driver of pulmonary and extrapulmonary manifestations of COVID-19. The optimal management strategy to prevent thrombosis in critically-ill patients with COVID-19 remains unknown. ⋯ INSPIRATION and INSPIRATON-S studies will help address clinically-relevant questions for antithrombotic therapy and thromboinflammatory therapy in critically-ill patients with COVID-19.

Meta AnalysisVenous thromboembolism in patients with COVID-19: Systematic review and meta-analysis.
Venous thromboembolism (VTE) may complicate the course of Coronavirus Disease 2019 (COVID-19). ⋯ VTE represents a frequent complication in hospitalized COVID-19 patients and often occurs as PE. The threshold for clinical suspicion should be low to trigger prompt diagnostic testing.

ReviewLemierre syndrome: Current evidence and rationale of the Bacteria-Associated Thrombosis, Thrombophlebitis and LEmierre syndrome (BATTLE) registry.
Lemierre syndrome is a rare but potentially fatal condition characterized by septic thrombophlebitis of the head and neck district, preferentially affecting adolescents and young adults and manifesting as a complication of a local bacterial infection - typically, a pharyngotonsillitis or an abscess. It is historically associated with the Gram-negative anaerobic rod Fusobacterium necrophorum and with thrombophlebitis of the internal jugular vein. ⋯ There are no specific guidelines on its management other than usual antibiotic stewardship, with ongoing debate on the potential role of therapeutic-dose anticoagulation. We provide an overview of current evidence on the definition, epidemiology, clinical presentation, prognosis and management of this condition and present the background and rationale of the Bacteria-Associated Thrombosis/Thrombophlebitis and LEmierre syndrome (BATTLE) registry: an ambispective, disease-specific, non-population based, multicentre clinical registry of global reach and multidisciplinary scope, specifically designed to address the limitations of current evidence and to provide patients and physicians with clinically viable information to guide management and improve the outcomes of those affected by these conditions.

Venous thromboembolism and bleeding in critically ill COVID-19 patients treated with higher than standard low molecular weight heparin doses and aspirin: A call to action.
Critically ill COVID-19 patients have a clear pattern of inflammation and hypercoagulable state. The main aim of the study was to evaluate the outcome of severe COVID-19 patients basing on prothrombotic risk factors (i.e. D-dimer). We also evaluated the impact of different doses of low molecular weight heparin (LMWH) on the incidence of bleedings. ⋯ More severe critically ill COVID-19 patients have a high incidence of VTE and worse outcome, despite the use of heparin at the therapeutic dose. However, the use of heparin did not increase the incidence of bleeding complications.

Comparative Study Observational StudyCoagulation parameters and venous thromboembolism in patients with and without COVID-19 admitted to the Emergency Department for acute respiratory insufficiency.
In the recent outbreak of COVID-19 pandemic, increased D-dimer levels and high rates of venous thromboembolic events were reported. We aimed to compare coagulation parameters on admission between COVID-19 patients and non-COVID-19 patients with acute respiratory insufficiency and to describe VTE diagnosed at entry. ⋯ D-dimer levels were similarly increased in patients with and without SARS-CoV 2 related disease. There were few cases of asymptomatic deep vein thrombosis or symptomatic pulmonary embolism at first day of admission, similarly distributed between COVID19 patients and non-COVID19 patients.
