For anyone unfamiliar with Grand Rounds in the blogosphere, it's a medical blog carnival. With posts submitted by doctors, patients, and generally medically-interested readers, there's usually a little something for everyone. This week's edition is located over at GruntDoc (you can read some background on GruntDoc at "Pre-Rounds" here--requires free registration.) Lots of good posts this week as usual. A few that caught my eye: a post a Parallel Universes discussing a recent Lancet paper on iron supplementation and malaria; some commentary at Red State Moron on prenatal diagnosis and termination of pregnancy: are patients getting the right information, and are they pressured one way or another by their OB/GYN?; and a discussion of the hedgehog pathway in obesity and osteoporosis over at The Biotech Weblog (which was also mentioned here at afarensis).
