Researchers followed 207 patients who survived intracerebral hemorrhage and found no increased risk of second hemorrhage among those taking antiplatelet therapy. The location of the original hemorrhage was associated with a higher risk of recurrence, particularly in the cerebral cortex.
A clinical trial found that epidural injections of steroids and local anaesthetics provided modest pain relief for shingles patients, but did not prevent chronic pain. The treatment was most effective during the first week after injection, but its effects were short-lived.
A sex-specific meta-analysis of aspirin therapy found that it reduced cardiovascular events by 12% in women and 14% in men. However, it increased the risk of major bleeding events in both sexes. The study suggests that aspirin should be considered for primary prevention in both men and women with preexisting cardiovascular disease.
A new meta-analysis of over 95,000 patients found that aspirin significantly reduces cardiovascular events in both men and women. However, the major reasons for this risk reduction differ between the sexes, with aspirin lowering the risk of heart attacks in men and stroke in women.
Researchers found that patients who consistently took aspirin had a 42% reduction in risk of death, while beta-blocker and lipid-lowering medicine users saw 37% and 48% reductions respectively. However, consistent use was low for these medications, with only 71% of aspirin users taking it regularly.
