Jacob Reider and his cohorts recently added an RSS feed to their RSS aggregator: Medlogs.com - The News Aggregator for Medical Topics.
The initial version didn't render well on Bloglines -- it included a section of unwanted descriptive text. Jacob has just fixed that it looks quite good now.
I now get my medlogs in the same space as my other syndicated reading. (So is Bloglines a meta-aggregator, since it's getting a feed from an aggregator?)
