Big news #ESC2023 and @NEJM
In a placebo-controlled randomized trial of people with obesity + heart failure (with preserved ejection fraction). semaglutide (Wegovy) markedly improved symptoms, exercise time, reduced inflammatory markers (and weight loss)…

This also tells us something about the underlying mechanism of heart failure with preserved EF—metabolic dysfunction and attendant systemic inflammation—not previously acknowledged or confirmed

My interview with @AshishKJha46, leader of the @WHCOVIDResponse, about the pandemic
We covered many important issues🧵…
1. Underuse of Paxlovid in older patients: not backed up by low incidence of rebound and ease of sidestepping potential drug interactions 2. Pharmacists unwilling to prescribe Paxlovid, even though empowered (these are results from new @Medscape survey)
3. Dr. Jha is a champion for developing nasal and universal coronavirus vaccines and explains why it hasn't happened (yet)

Today there are 3 new reports that strongly reinforce that
1. Comparing bivalent vs original for protection vs hospitalizations & deaths 2. Superior neutralizing antibodies vs the new variants with marked immune evasion: XBB.1, BQ.1.1, BA.2.75 compared with the original booster (adds to 12 lab studies)

The #AI takes the medicine qualifying exam.
Three to take note:
1. China, 2017, Xiaoyi passed the licensing exam with a score of 456 (passing 360-600) based on memorization and information recall, with poor performance on patient cases 2. UK, 2022, the machine took the radiology qualifying exam, compared with 26 radiologists who recently passed. Overall accuracy 79.5% compared with 84.8% for the radiologists.

A new retrospective nationwide EHR assessment of #LongCovid in ~230,000 people w/ mild Covid and matched controls for age, sex, vaccination status, variant
Some downplaying of persistent symptoms at 1 year:
1. Median age of cohort = 25 years. People age 41-60 had worse outcomes 2. Major symptoms of difficulty breathing, cognitive impairment and weakness were present at 1 year. Also loss of smell, taste, dizziness and cough
