The inflammatory bowel diseases of ulcerative colitis and Crohn disease are chronic inflammatory conditions of the intestine. The estimated incidence of ulcerative colitis is 15 per 100 000 person-years and the prevalence is 400 per 100 000 in North America.

In Reply Although the available data suggest that, in patients with atrial fibrillation, sex is not associated with serious oral anticoagulant-related bleeding, as suggested by Dr Samuelson Bannow and colleagues, we analyzed the interaction between diltiazem and apixaban/rivaroxaban according to sex. The cohort included 107 652 females with a mean age of 77.8 (SD, 7.2) years and 96 503 males with a mean age of 75.9 (SD, 6.6) years. The outcome was the composite of bleeding-related hospitalization or death with recent evidence of bleeding... Читать дальше...

To the Editor A recent study reported a higher incidence of serious bleeding in patients using diltiazem, compared with metoprolol, in conjunction with apixaban or rivaroxaban for the treatment of atrial fibrillation. The authors also reported a higher proportion of women in the diltiazem group (59.3% vs 50.4%).

As highlighted previously by the USPSTF and others, there is an urgent... Читать дальше...
