Use of Intravenous Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke Patients Taking Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) Before Stroke

European Heart Journal

Analysis of registry data on 42,887 ischaemic stroke patients (251 on NOACs; 1500 on warfarin before stroke) treated with intravenous rt-PA within 4.5 hours found no significant difference in symptomatic intracranial haemorrhage in anticoagulated(AC'd) vs. non-AC'd patients.

 

Similar Efficacy of Proton-Pump Inhibitors vs H2-Receptor Antagonists in Reducing Risk of Upper Gastrointestinal Bleeding or Ulcers in High-Risk Users of Low-Dose Aspirin

Gastroenterology

RCT (n=270) found lower proportion of patients on PPI developed recurrent upper GI bleeding (0.7 v 3.1%) and reached composite end point of recurrent
bleeding/endoscopic ulcers at month 12 (7.9 vs. 12.4%) vs. H2 antagonist group, but difference was not statistically significant.

 

Individualized venous thromboembolism risk using the 2005 Caprini score to identify the benefits and harms of chemoprophylaxis in surgical patients: a meta-analysis

Annals of Surgery

This analysis of 13 studies (n=14,776) concludes benefit of peri-operative VTE chemoprophylaxis was only found among surgical patients with Caprini scores
≥7. Patients with scores ≤6 comprised 75% of overall population and did not show a VTE risk reduction with chemoprophylaxis.

thromboembolism in ambulatory cancer patients treated with chemotherapy.
