Clinical impact and course of major bleeding with edoxaban versus vitamin K antagonists

Thrombosis and Haemostasis

Analysis of major bleeding events from Hokusai-VTE study (n=8240) suggests edoxaban associated major bleeding events have similar presentation/course compared to those with vitamin K antagonist (56 and 65 events, respectively) in patients treated for venous thromboembolism.

 

Low dose oestrogen combined oral contraception and risk of pulmonary embolism, stroke, and myocardial infarction in five million French women: cohort study

British Medical Journal

This study (n=5,443,916) found that for the same dose of oestrogen, desogestrel and gestodene were associated with statistically significantly higher risks of pulmonary embolism but not arterial thromboembolism compared with levonorgestrel.

 

Low-Dose versus Standard-Dose Intravenous Alteplase in Acute Ischemic Stroke

New England Journal of Medicine

This open label study (n=3310) in mainly Asian patients low-dose alteplase (tPA) did not show non-inferior to standard-dose tPA with respect to death and disability at 90 days. There were significantly fewer symptomatic intracerebral haemorrhages with low-dose tPA.

 

Ticagrelor versus Aspirin in Acute Stroke or Transient Ischemic Attack

New England Journal of Medicine

This RCT (n=13,199) found that ticagrelor was not superior to aspirin in reducing the rate of stroke, myocardial infarction or death at 90 days (HR=0.89, 95%CI= 0.78-1.01, p=0.07).

 

Platelet transfusion versus standard care after acute stroke due to spontaneous cerebral haemorrhage associated with antiplatelet therapy (PATCH): a randomised, open-label, phase 3 trial

The Lancet

In this open label trial (n=190) the odds of death or dependence at 3 months were higher in the platelet transfusion group than in the standard care group (adjusted OR 2•05, 95% CI 1•18–3•56).

 

Systematic review of prognostic models for recurrent venous thromboembolism (VTE) post-treatment of first unprovoked VTE

BMJ Open

This review identified 3 models, HERDOO2 score, Vienna prediction model and DASH score, for predicting the recurrence risk of VTE and concluded that none of these can be considered ready for use until further external, robust validation is performed in new data.
