Venous thromboembolism (VTE), which includes pulmonary embolism and deep vein thrombosis, carries significant morbidity and mortality risks, and is conventionally managed with anticoagulation. In recent years, notable progress has been made in the therapeutic options available for the acute treatment of VTE. The heterogeneity within pulmonary embolism, spanning a wide spectrum of risks, underscores the critical need for precise risk stratification, particularly in identifying individuals prone to right heart failure and increased mortality.

Background: The recently published PEERLESS trial compared catheter-directed thrombolysis (CDT) and catheter-based thrombectomy (CBT) in acute pulmonary embolism (PE). However, it included a low proportion of patients with contraindications to thrombolytic therapy (4.4%), leaving uncertainty about how CDT would perform relative to CBT in a real-world cohort with higher bleeding risk.

Article Synopsis
  • SARS-CoV-2 is evolving, resulting in new variants like XEC, which has specific mutations (T22N and F59S) in the spike protein that affect how the virus interacts with neutralizing antibodies.
  • The study analyzed immune responses from different vaccinated groups and found that XEC had significantly lower neutralization levels due to the F59S mutation, but removing certain glycosylation sites could restore these levels.
  • The research highlights that mutations in the N-terminal domain of the spike protein play a crucial role in the virus's ability to evade the immune system and change its structural properties.
