Risk factors associated with cerebral infarction within 7 days after off-pump coronary artery bypass grafting require further statistical elucidation. ⋯ Multivariate analysis identified independent factors strongly associated with cerebral infarction after off-pump coronary artery bypass grafting, such as partial aortic clamping, presence of cerebral ischemic symptoms plus head and neck vascular lesions, and previous cerebral infarction.

We describe 3 patients with methicillin-resistant Staphylococcus aureus, hospital-acquired pneumonia who demonstrated a microbiological and clinical failure with vancomycin despite adequate trough levels. All 3 patients were cured with linezolid.

Cardiac troponin I (cTnI) measured after heart surgery has been associated with operative mortality. We sought to determine whether measuring cTnI after heart surgery provides additional prognostic information beyond that provided by validated preoperative risk scores, the Veterans Affairs (VA) risk score and the European System for Cardiac Operative Risk Evaluation (EuroSCORE). ⋯ Postoperative cTnI measured 24 hours after heart surgery is independently associated with operative death and perioperative myocardial infarction and improves the ability to predict operative mortality in comparison with preoperative risk scores alone.
