🎙️Ecstatic to share a podcast interview with @drjohnm from @Sensible__Med about analytic flexibility and nutritional epidemiology.🍎🥩 Hear the podcast: sensible-med.com/p/a-discuss… Read the paper: linkinghub.elsevier.com/retr… @MacAnesthesia @HEI_mcmaster @machealthsci
You all. I found a beautiful study to write about @Sensible__Med. A new way to analyze observational studies. Gosh, I am excited. Not only to find this study but also to talk with senior author @DenaZera Post here sensible-med.com/p/the-defin… Podcast tomorrow.

💊 What do drug treatments actually offer people living with fibromyalgia? Our review is out in BMJ Medicine. Bottom line: benefits are mostly small, and evidence is low certainty. Honest conversations about expectations are key. bmjmedicine.bmj.com/content/…

Our @BMJMedicine network meta-analysis (151 trials) found no moderate or high-certainty evidence that any drug provides important benefits for fibromyalgia. Some drugs may help some patients - evidence is low certainty and benefits are typically small:bmjmedicine.bmj.com/content/…

A systematic review takes one to two years. Very little of that time goes to thinking. It goes to moving citations between disconnected tools. We built CoreSR to strip that out and return the reviewer's time to judgment. youtube.com/@CoreSR coresr.ai/

"A significant fraction of the reporters covering the FDA and pharmaceutical industry have developed, over years of access journalism, a set of relationships and sympathies that align them more closely with the companies they cover than with the regulatory mission"

👁️ Our editorial outlines how ophthalmologists, researchers, and guideline developers can use the GRADE evidence-to-decision (EtD) and the GRADE-Adolopment to create trustworthy clinical practice guidelines. 🔗 Full editorial: nature.com/articles/s41433-0…

Super proud of @TylerSC10 ! Amazing work! ⭐️
🚨 Excited to share our new paper in @LancetRespirMed 🚨 Our systematic review & network meta-analysis compares preoxygenation strategies for critically ill patients needing intubation. NIPPV tops HFNC & facemask in reducing hypoxaemia. 🔍 Study Highlights • Systematic review & network meta-analysis of 15 RCTs (n=3420) • Compared HFNC, NIPPV, and facemask oxygen for preoxygenation • NIPPV likely best at reducing hypoxaemia during intubation   – vs HFNC: RR 0.73 (moderate certainty)   – vs facemask: RR 0.51 (high certainty) • HFNC better than facemask: RR 0.69 (high certainty) • No strategy improved first-attempt intubation success • NIPPV may reduce serious adverse events vs HFNC/facemask • No clear mortality difference between methods • Data used to inform upcoming international airway guidelines 🧠 Implications: NIPPV may be preferred in high-risk or critically ill patients; findings support evidence-based guideline updates kwnsfk27.r.eu-west-1.awstrac… @UofT_DoM @MacDeptMed @Bram_Rochwerg @DenaZera @HEI_mcmaster

🚨 New Clinical Guidelines Alert 🚨 A major review recommends against commonly used interventional procedures like epidural injections, nerve blocks & ablations for chronic spine pain Why? ❌ Similar benefits to sham, potential risks, & high costs bmj.com/content/388/bmj-2024…

What leads us to ignore experts isn't their knowledge. It's their arrogance. Evidence: Scientists are more credible when they admit what they don't know, acknowledge what they got wrong, and update their views. Trust is earned by expressing humility, not by asserting authority.
