Several reports of various bleeding problems associated with the use of serotonergic antidepressants have been published. However, no information concerning the effect of these drugs on perioperative blood loss and blood transfusion requirements during orthopedic surgery is available. The objective of this study was to determine the association between use of serotonergic antidepressants and perioperative blood loss and transfusion in orthopedic surgical patients. ⋯ Use of serotonergic antidepressants is associated with an increased risk of bleeding and subsequent need for blood transfusion during orthopedic surgery. The bleeding could be attributed to inhibition of serotonin-mediated platelet activation.

Multicenter Study
Communitywide trends in the use and outcomes associated with beta-blockers in patients with acute myocardial infarction: the Worcester Heart Attack Study.
Despite the benefits associated with beta-blocker therapy in patients with acute myocardial infarction (AMI), limited recent data are available describing the extent of use of this therapy and the associated hospital and long-term outcomes, particularly from the perspective of a population-based study. Data are also limited about the characteristics of patients with AMI who do not receive beta-blockers. This study examines more than 2 decades of trends in the use of beta-blockers in hospitalized patients with AMI. ⋯ The results of this observational study demonstrate encouraging trends in the use of beta-blockers in hospitalized patients with AMI and document the benefits to be gained from this treatment.

Comparative Study
Risk of mortality by histologic type of breast cancer among women aged 50 to 79 years.
Recent studies suggest that the use of combined estrogen and progestin hormone replacement therapy is associated with an increased risk of invasive lobular carcinoma (ILC), but that it has little association with risk of invasive ductal carcinoma (IDC). Also, the incidence rates of ILC have risen over the past 10 years while those of IDC have remained constant. Differences in survival rates by histologic types of tumor have been reported, but few of the published studies were population based or had adequate power to address this issue. ⋯ Differences in prognosis by histologic type of breast cancer were identified. The survival rate of women 50 to 79 years old who have ILC, the cancer whose histologic type is the most closely linked with the use of combined estrogen and progestin hormone replacement therapy, is more favorable than that of women with IDC and appears to be improving over time.

Survivors of major vascular surgery are at increased risk of late cardiac complications. ⋯ Long-term beta-blocker use is associated with a reduction in the cardiac event rate, except for patients with 3 or more risk factors and positive findings on DSE.

We compared perceptions regarding risk of cardiovascular events and benefits of cardiovascular disease (CVD) risk factor reduction between patients with peripheral arterial disease (PAD), patients with coronary artery disease (CAD), and patients without atherosclerosis (no disease). ⋯ Compared with other patients, those with PAD underestimated the high risk of cardiovascular events associated with PAD and the benefits of cholesterol-lowering therapy. These findings may help explain the low rates of CVD risk factor control previously reported in patients with PAD.
