Smoking is the leading PREVENTABLE cause of death. ~11% Canadians smoke, with rates 2x higher in hospitalised patients & even more among surgical patients. Upcoming CPU focuses on contemporary approaches for the practicing clinician. Systematic approaches are crucial.

Reflecting on my PhD defence, the external examiner's kind congratulatory remarks before the very rigorous critique of the thesis was instrumental in how I received and addressed the feedback. Kindness costs nothing but gives everything. I take that with me as an examiner.

@hvanspall Oh my Harriette, my heart breaks for you as I read the raw emotion in this piece. I know this ache intimately as my own father, a doctor himself, was failed by a healthcare system he had poured his life into. I’m so sorry and that you could forgive speaks to your heart 🫂

@venkmurthy I submitted a paper Nov 25, 2025. It is March 7, 2026 and they have not been able find reviewers🤦🏽‍♀️ It is never ending.

Completely agree @DrMarthaGulati We need large RCTs in contemporary populations to inform evidence based care for all forms of menopausal hormone replacement therapy.

[Dr. Martha Gulati ♥️🫀❤️‍🩹🇨🇦 @DrMarthaGulati]

Today the Black Box was removed from ALL Menopausal Hormone Therapy (MHT). For transvaginal, I think this is reasonable, but what do we actually know about contemporary doses of transdermal & oral #MHT? I also think the statements being made are doing a huge disservice to women. This is NOT a win for women. A win would be funding a trial that studies women on contemporary doses of transdermal & oral MHT.

The statement by Makary that "With the exception of vaccines or antibiotics, there's no medication that can improve the health of women on a population level more than hormone replacement therapy," is not based on fact. We just don’t know and certainly any statement on cardiac safety remains unknown for contemporary doses of transdermal and oral MHT

I want to care for women using evidence based treatments. We have seen by many examples of what can happen when we don’t study women. Let’s not do this again.

Yea the science is nice, but finally
meeting the incredible @DrMarthaGulati is so much nicer! 😊 A global leader in women’s health and equity for women in cardiology. #ESCCongress2025

@DrMarthaGulati @mmamas1973 @iamritu @purviparwani Same today as well. Even though my run was later closer to 7. When you see people with their heels in hand, you can tell a time was had. Madrid nights must be fun! 😃

[Sandra O, MBBS, MSc, PhD @docSandraO]

Very inspiring to have these amazing scientists doing impactful work to look up to, and importantly, to work alongside with at the PHRI. Huge congrats to all the recipients 👏🏽

[Sandra O, MBBS, MSc, PhD @docSandraO]

Scarcity culture forces brilliant people to compete for crumbs and then internalize the result. When you are not "chosen", sometimes it just means there were not enough chairs at the table, not that you don't belong. You are doing the work, and that is enough today.

#GRADE, indeed #EBM, will never be the same. GRADE papers have become too complex and difficult to navigate. The remedy: a series of 7 papers in the #BMJ laying out the essentials of GRADE: Core GRADE. This week, an overview of Core GRADE.
