Gender‑Affirming Hormone Therapy and Acute Cardiovascular Events: Dutch Cohort Finds Lower MI but Higher VTE in Transgender Women, Elevated MI and Stroke Risk in Transgender Men

Gender‑Affirming Hormone Therapy and Acute Cardiovascular Events: Dutch Cohort Finds Lower MI but Higher VTE in Transgender Women, Elevated MI and Stroke Risk in Transgender Men

A large Dutch cohort study found that after adjusting for socioeconomic status and lifestyle, transgender women on oestradiol had lower myocardial infarction (MI) risk but higher venous thromboembolism (VTE) risk; transgender men on testosterone had higher MI and ischaemic stroke risk.
Rare but Real: Higher Risks of Vascular and Inflammatory Disease After SARS‑CoV‑2 Infection Than After BNT162b2 Vaccination in Children and Adolescents

Rare but Real: Higher Risks of Vascular and Inflammatory Disease After SARS‑CoV‑2 Infection Than After BNT162b2 Vaccination in Children and Adolescents

A nationwide English cohort study (n≈13.9M) found transient but significant increases in rare vascular and inflammatory events after first SARS‑CoV‑2 infection and a smaller, short-lived increase in myocarditis/pericarditis after first BNT162b2 vaccination—supporting vaccination to reduce greater risks from infection.
Continuing Anticoagulation After Unprovoked VTE Lowers Recurrence but Raises Bleeding — Real‑World Target Trial Emulation Shows Net Clinical Benefit

Continuing Anticoagulation After Unprovoked VTE Lowers Recurrence but Raises Bleeding — Real‑World Target Trial Emulation Shows Net Clinical Benefit

A large target‑trial emulation of US claims data found continued oral anticoagulation after ≥90 days for unprovoked VTE markedly reduced recurrent VTE and mortality, increased major bleeding, but produced an overall net clinical benefit that persisted through several years of follow‑up.
Cold Agglutinin Syndrome Secondary to Mycoplasma pneumoniae Infection in Adults: Insights from a Large French Observational Study

Cold Agglutinin Syndrome Secondary to Mycoplasma pneumoniae Infection in Adults: Insights from a Large French Observational Study

A national French study reveals that cold agglutinin syndrome (CAS) develops about 10 days after Mycoplasma pneumoniae infection onset, often requiring ICU care and transfusions, with a generally favorable prognosis despite frequent venous thromboembolism and no clear benefit from glucocorticoid treatment.
