Episode 38: New trials you need to know about

In episode 38 we try to go over 8 new studies in one podcast but only get half-way there. We cover 2 inhaled anticholinergic studies, one new glucose lowering trial and the latest smoking cessation RCT. Mike and James wax poetically about a variety of issues and demonstrate clearly their well-honed technique of how not to stay foccussed, succint and to-the-point which explains why we only got to half the studies.

Show Notes

1) Inhaled anticholinergics – for better or worse?

Tiotropium given for 4 years on-top of existing therapy – no increase in mortality and fewer myocardial infarctions

N Engl J Med 2008;359:1543-54

Inhaled anticholinergics increases risk of cardiovascular death – but not total mortality

JAMA 2008;300:1439-1450

2) VADT – trial – the third study showing either no benefit or harm from aggressively lowering blood glucose – glycated hemoglobin level reduced from 8.4% to 6.9%

N Engl J Med 2009;360:129-39

3) Varenicline for smoking cessation Varenicline verus transdermal nicotine

Thorax 2008;63:717-24

Evidence showing 0.5 mg BID of varenicline is as effective as 1 mg BID

FDA document

Episode 37: Diverse listener questions and comments – Q & A with no QA

In Episode 37, we again review listener questions and comments around such diverse topics as Bell’s Palsy, viruses that break bones, glucose monitoring, glitazones and COPD. Both James and Mike give diverse answers with diverse meanings that even they don’t really understand.

Show Notes

1) The third study showing either no benefit or harm from aggressively lowering blood glucose – glycated hemoglobin level reduced from 8.4% to 6.9%

NEJM 2009;360:129-39

2) Studies of monitoring blood sugar in type 2 diabetics showing no benefit and increased depression scores

3) Beta-blockers and thiazides do appear to increase the chance of developing diabetes

4) 10-year follow-up of intensive glucose control in Type 2 diabetes

NEJM 2008;359:1577-89

5) COPD guidelines recommending inhaled steroids as one of the first line inhalers

Ann Int Med 2007;147:639-53

Episode 36: Information on older drugs from an even older doctor – Part II

In episode 36, we take up where we left off in episode 35 by reviewing eight more (not ten) old drugs that hopefully you are still using – if not, get with the progam – in your day-to-day practice. Dr Bob joins us yet again for this episode and provides us with some great clinical experience and finally some reasonable humour. Mike tries to deliver some useful clinical pearls and James tries to keep things flowing smoothly – neither have tremendous success.

Episode 35: Information on older drugs from an even older doctor

In this first episode of the New Year (Episode #35) we review nine (not ten) old drugs that should, in most circumstances, still likely play an important role in your day-to-day prescribing and recommendations. Dr Robert Rangno again joins us for this episode and provides us with some great clinical experience and some mediocre humour. Mike and James, as usual laugh about a variety of things that in hindsight really aren’t all that funny.
