COVID-19-associated coagulopathy in children: A multicenter observational cohort study.

SARS-CoV-2 infection (coronavirus disease 2019 [COVID-19]) induces a stark procoagulant state, with many hospitalized adults developing thrombosis despite prophylactic anticoagulation. This study aimed to characterize hemostatic parameters and associated clinical outcomes of COVID-19, such as thrombosis and bleeding, in children and to assess thromboprophylaxis use. This multicenter observational cohort study included 79 patients aged up to 18 years admitted to all pediatric hospitals in Québec, Canada, with SARS-CoV-2 infection during a 5-month period.

Repurposing alpelisib, an anti-cancer drug, for the treatment of severe TIE2-mutated venous malformations: Preliminary pharmacokinetics and pharmacodynamic data.

Extensive venous malformations involving limbs severely impact quality of life, mostly due to chronic pain and functional limitations. But patients can also display coagulopathy with associated risks of life-threatening thromboembolism and bleeding. Available pharmacological treatments (e.
