Episode 205: Please stop measuring all those A1c levels – PART II

In episode 205, Mike and James continue with their discussion on the use of A1c levels in type-2 diabetes. We discuss the variability in the measurement of A1c and given this, how tricky it is to use the A1c once therapy has been started. We also discuss the magnitude of the vascular benefit of therapies that change A1c and come to the conclusion that with all this confusion “minimally disruptive medicine” seems to make a lot of sense.

Episode 204: Please stop measuring all those A1c levels

In episode 204, James and Mike get into a discussion about the use of A1c levels for diagnosing and treating type-2 diabetes. We discuss screening recommendations and the impact an elevated A1c has on cardiovascular disease and other outcomes. At the end we realize the key message is that we have to let patients know that having an elevated A1c does not indicate impending doom.

Episode 203: PREMIUM – Vitamin D, chelation therapy, and obesity studies you need to know about

In episode 203, James and Mike go all PREMIUM and discuss three new studies. Vitamin D for the common cold, chelation therapy post-MI and the link between obesity and mortality. If you are reading this and you are a non-PREMIUM member, boy are you missing something.

Episode 202: Please stop measuring all those bone densities

In episode 202, Mike and James continue their testing deconstruction process. This week they take on bone mineral densities and discuss when (almost never) and when not to get these measurements. The podcast clocks in at a dense 44 minutes but the result is a real gem (mineral).
