Association of Age With 10-Year Outcomes After Coronary Surgery in the Arterial Revascularization Trial.

Background: The association of age with the outcomes of bilateral internal thoracic arteries (BITAs) versus single internal thoracic arteries (SITAs) for coronary bypass grafting (CABG) remains to be determined.

Objectives: The purpose of this study was to evaluate the association between age and BITA versus SITA outcomes in the Arterial Revascularization Trial.

Methods: The primary endpoints were all-cause mortality and a composite of major adverse events, including all-cause mortality, myocardial infarction, or stroke.

Predicting meniscal tear stability across knee-joint flexion using finite-element analysis.

Purpose: To analyse the stress distribution through longitudinal and radial meniscal tears in three tear locations in weight-bearing conditions and use it to ascertain the impact of tear location and type on the potential for healing of meniscal tears.

Methods: Subject-specific finite-element models of a healthy knee under static loading at 0°, 20°, and 30° knee flexion were developed from unloaded magnetic resonance images and weight-bearing, contrast-enhanced computed tomography images. Simulations were then run after introducing tears into the anterior, posterior, and midsections of the menisci.
