July/August 2007 Annals of Family Medicine tip sheet

A four-year study of 1,869 women found that the Active Management of Risk in Pregnancy at Term approach resulted in lower cesarean delivery rates compared to traditional care. Preventive labor induction also appeared to lower adverse birth outcomes. The findings challenge current beliefs about labor induction and suggest a preventive a...

Hip and knee replacements rarely performed in patients over 100

A new study found that hip and knee replacements are rarely performed in patients over 100 due to concerns about short-term life expectancy. However, the research suggests that these procedures should not be denied solely based on age and that the benefits may outweigh the risks.
