These are almost universally excellent. I burn a few per week to listen to on the way to the hospital. Summaries of recent original articles to answer focused clinical questions, with some discussion of relevent background. Just don't forget to read the actual article if you plan to integrate results into your practice.
They give the best medical literature reviews out there! By just listening to what they discuss, you can learn easily how to critically analyze medical literatures. This is a short version of Journal club!! Awesoooomme!!
