Children's exposure to violence in the media is a possible source of public health concern; however, violence in children's animated films has not been quantified. ⋯ Our content analysis suggests that a significant amount of violence exists in animated G-rated feature films. Physicians and parents should not overlook videocassettes as a source of exposure to violence for children. JAMA. 2000;283:2716-2720.

Meta Analysis
Mortality and prehospital thrombolysis for acute myocardial infarction: A meta-analysis.
Early administration of thrombolysis for acute myocardial infarction (AMI) may improve survival if safely and appropriately delivered. No systematic reviews that have comprehensively examined this topic exist in the literature. ⋯ Our meta-analysis suggests that prehospital thrombolysis for AMI significantly decreases the time to thrombolysis and all-cause hospital mortality. JAMA. 2000;283:2686-2692.

Hemodynamic monitoring of patients with a pulmonary artery catheter is controversial because there are few data confirming its effectiveness, and patient and intensive care unit (ICU) organizational factors associated with its use are unknown. ⋯ Organizational characteristics of ICUs, insurance reimbursement, and race, as well as clinical variables, are associated with variation in practice patterns regarding pulmonary artery catheter use. Understanding such influences, combined with studies measuring clinical and economic outcomes, can contribute to the development of policies for the rational use of pulmonary artery catheters.
