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.

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.

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).

In episode 201, James and Mike continue on with deconstructing the concept of cholesterol measuring and lowering. We talk about various scenarios as to when one could measure cholesterol but quickly come to the realization that if one looks at the best science and uses a logical thought process, the whole concept of cholesterol measurement for individual patients is unfortunately built upon a house of cards.

In episode 200, James and Mike unveil the new BS Medicine Podcast. For their first topic they rant on and on about why most cholesterol measurements are pretty much a waste of time. We talk about how the breakpoints are arbitrary and lack any specific logic and that given the within-person variation, annual measurements really don’t have any value. At the end we brilliantly segue to a discussion on cranberry juice for UTIs.

Hi Everyone: Well, after 5 years, 199 episodes, ~ 120 hours of content = 24 hours a day for 5 days, James and Mike have decided to pull the plug on the TEC podcast. We want to thank all the listeners – some who have listened to them all – for trusting in the content that we provide.

BUT DON’T YOU WORRY.

We are coming back with more of the same and maybe a little bit more. We’ve never really liked the name “TEC podcast” so we’ve decided to make a name change and a logo change.

From now on the podcast will be known as

The Best Science (BS) Medicine Podcast – BS without the BS

Hope you like the change and let us know what you think.

In episode 199, Mike, James and Adil finish off the ADHD series by talking about the side effects and concerns for the stimulants and the evidence behind the use of non-stimulant medications. At the end Mike and James are so excited about the upcoming 200th episode they can hardly sit still so Adil starts a stat stimulant infusion on both of them.

In episode 198, we bring back Adil Virani yet again to help us work through the evidence for stimulants, which one to choose, what dose to start with, what to monitor, and how long to stay on the medications. We pay very close attention to the very end.

In episode 197, James and Mike bring in our good friend and colleague Adil Virani to help us to discuss the issue of ADHD. In this first part we discuss the diagnosis and try to focus on the concept of improving function rather than necessarily improving ADHD symptoms. At the end we all lose focus but realize this is exactly what has happened in the previous 196 episodes.

In episode 196, Mike and James squeeze into the literature and look to see if there is a role for drinking cranberry juice in the prevention of urinary tract infections. Given the cost and caloric intake we lean towards prophylactic antibiotics and lean even further towards a 3-day course of antibiotics when symptoms occur.
