Medication Mythbusters – Home of the Best Science (BS) Medicine Podcast

The BS Medicine Podcast episodes are presented by James McCormack and Michael Allan. We try to promote healthy skepticism and critical thinking and most of the podcasts are presented in a case-based approach. We also try to inject some humour into the whole process to make the learning more interesting. Occasionally we have great guests like Mike Kolber, Tina Korownyk and Bruce Arroll help us out.

Most podcast episodes are available for free until they become archived after about 1-2 months. Every 4th episode or so is a “New Studies You Need to Know About” podcast and these will only be available to our Premium Podcast members. Premium members will also be able to listen to all archived episodes since episode #1.

Episode 465: COPD inhalers – the evidence leaves you gasping for breath

In episode 465, Mike and James invite Jamie Falk to go over all the data we have for the plethora of inhalers and COPD. We start with what we know about single puffers, how we decide whom to treat, and then when to try dual inhalers.

2) Should the number of acute exacerbations in the previous year be used to guide treatments in COPD?

Episode 464: PREMIUM – 4 new publications that should change your practice

In episode 464, Mike and James and talk about 4 recent publications that should likely impact you practice if not today, then tomorrow. We talk about how long to give narcotics for acute MSK injuries, how to treat dyslipidemias, a non-steroid cream for psoriasis and a single dose of antibiotics for operative vaginal delivery.

Episode 462: Before you lower blood pressure to 120, listen to this podcast

In episode 462, James and Mike invite Scott Garrison to talk about some important nuances around guideline recommendations and how low we should lower systolic blood pressure. We look in detail at the SPRINT trial and then come up with a reasonable (in our minds) approach to what thresholds we should use.

Episode 459: Is 45 really the new 50 in colorectal cancer screening?

In episode 459, James and Mike invite Mike Kolber to talk about whether or not the increased rate of colorectal cancer in people under 50 means we should be screening earlier. We talk about all the numbers and put the risk into the context of the absolute numbers.

Episode 458: PREMIUM – So many new studies you need to know about

In episode 458, James and Mike finally get back to being PREMIUM and cover a number of new and useful RCTs. We discuss 4 new Vitamin D trials, atrial fibrillation and do you need both rate and rhythm control, swollen legs and cellulitis, and is colchicine the new statin. Check out the PREMIUM podcast for all the answers.

Episode 457: Who let the Gout Out? Targeting Uric Acid Levels in Treating Gout

In episode 457, James and Mike yet again invite Joey Ton to go through the evidence around reaching a target serum urate level in patients with gout. As with many arbitrary thresholds determined from observational studies (sometimes), or just made up, when you properly study if there is a benefit to achieving these levels the theory really crumbles under the weight of the evidence. We also briefly talk about the febuxostat vs allopurinol data and the outcomes that matter.
