This study looked at whether having medical residents participate in breast cancer surgeries, specifically lumpectomies, affects the outcome of the surgery in terms of the margin status, which is crucial for preventing cancer from returning. The researchers found that the involvement of residents did not significantly change the number of surgeries resulting in positive margins, with 20.3% of cases involving residents having positive margins compared to 16.7% without them. The only factor that affected positive margins was a specific type of cancer, which was more frequently associated with higher margin rates, showing that residents can safely participate in these surgeries without increasing risks for patients. Who this helps: This helps patients undergoing breast cancer surgery, as it supports the safe training of new surgeons.

Plain English
This study reviewed existing research to explore whether the way babies are born (specifically, vaginal birth) affects the strains or deformities in their skulls. It found that while there is no clear link between vaginal birth and cranial base strains, prolonged labor and the use of tools during delivery are associated with increased skull issues in infants.
