ReviewWhat effects have resident work-hour changes had on education, quality of life, and safety? A systematic review.
More than 15 years ago, the Institute of Medicine (IOM) identified medical error as a problem worthy of greater attention; in the wake of the IOM report, numerous changes were made to regulations to limit residents' duty hours. However, the effect of resident work-hour changes remains controversial within the field of orthopaedics. ⋯ There is a paucity of high-level or clear evidence evaluating the effect of the changes to resident work hours. Future research in this area should focus on objective measures that include patient safety as a primary outcome.

rhPDGF-BB promotes early healing in a rat rotator cuff repair model.
Tendon-bone healing after rotator cuff repair occurs by fibrovascular scar tissue formation, which is weaker than a normal tendon-bone insertion site. Growth factors play a role in tissue formation and have the potential to augment soft tissue healing in the perioperative period. ⋯ Augmenting the healing environment to improve the structural integrity and to reduce the retear rate after rotator cuff repair may be realized with continued understanding and optimization of growth factor delivery systems.
