Apixaban or Vitamin K Antagonists and Aspirin or Placebo According to Kidney Function in Patients with Atrial Fibrillation After Acute Coronary Syndrome or PCI: Insights from The AUGUSTUS Trial

Circulation
Review of the AUGUSTUS trial (n=4,456, reporting apixaban caused less bleeding and fewer hospitalisations than vitamin K antagonists in AF after ACS or PCI) found the safety and efficacy of apixaban was consistent irrespective of kidney function, as compared with warfarin.

Effect of Endovascular Treatment Alone vs Intravenous Alteplase Plus Endovascular Treatment on Functional Independence in Patients With Acute Ischemic Stroke: The DEVT Randomized Clinical Trial

Journal of the American Medical Association
RCT in 234 patients with acute ischaemic stroke found endovascular treatment (EVT) alone was noninferior to i/v alteplase plus EVT (functional independence at 90 days was achieved in 54.3% vs 46.6% respectively, a difference that met the prespecified noninferiority margin of 10%).

Effect of Mechanical Thrombectomy Without vs With Intravenous Thrombolysis on Functional Outcome Among Patients With Acute Ischemic Stroke: The SKIP Randomized Clinical Trial

Journal of the American Medical Association
Trial in patients (n=204) with acute large vessel occlusion stroke failed to demonstrate non-inferiority (NI) of mechanical thrombectomy (MT) alone vs. combined i/v thrombolysis plus MT for favourable functional outcome (OR 1.09 [95% confidence limit below the NI margin of 0.74]).

Residual risks of ischaemic stroke and systemic embolism among atrial fibrillation patients with anticoagulation: large-scale real-world data (F-CREATE project)

Heart
In this Japanese retrospective cohort study (n=11,848), there were 0.57 cases of ischaemic stroke and systemic embolism per 100 person-years during mean of 3 yrs; 30% (95% CI 16.1-41.6%) of risk was attributable to modifiable risk factors (hypertension, diabetes, dyslipidaemia).

Positive Phase III results for valoctocogene roxaparvovec in the treatment of severe haemophilia A

Biospace Inc.
In the GENEr8-1 study (n=134), a single dose of valoctocogene roxaparvovec reduced annualised bleeding rate from a mean of 4.8 episodes per year at baseline to 0.8 per year, after a mean follow-up of 71.6 weeks (p<0.0001).

Revised SPC: Lixiana (edoxaban) Film-Coated Tablets – all strengths

electronic Medicines compendium

COVID-19, immunothrombosis and venous thromboembolism: biological mechanisms

Thorax
Review explores the pathobiological mechanisms of immunothrombosis and VTE in COVID-19 focusing on COVID-19-associated coagulopathy, pathology, endothelial dysfunction and haemostasis, the immune system and thrombosis, genetic associations and additional thrombotic mechanisms.

SSRI/SNRI antidepressant medicines: small increased risk of postpartum haemorrhage when used in the month before delivery

Medicines and Healthcare products Regulatory Agency
Data from observational studies suggest use of SSRI/SNRI antidepressants during month before delivery may result in small increased risk of postpartum haemorrhage. Prescribers should consider this risk vs. benefits of antidepressants for patient's mental health during this time.

Compression stockings in addition to low-molecular-weight heparin to prevent venous thromboembolism in surgical inpatients requiring pharmacoprophylaxis: the GAPS non-inferiority RCT

National Institute for Health Research
RCT (n=1,858) found pharmaco-thromboprophylaxis alone was non-inferior to a combination of pharmaco-thromboprophylaxis and graduated compression stockings in terms of venous thromboembolism up to 90 days after surgery (1.7% vs 1.4%, p<0.001 for non-inferiority).
