Should I tell anyone that I suspect misconduct in a paper I’m reviewing? So important and with more ECRs reviewing this guidance is very welcome. Things to keep in mind: - Extend the benefit of the doubt - Talk to the editor - Check your tone - Balance your responsibilities and your limits

An abs risk generalizable risk calculator is challenging. Led by @somijemmacho.bsky.social, evaluating AHA PREVENT across 4 academic health systems, we found similar discrimination but variable calibration. A universal abs risk threshold may not suitably guide www.sciencedirect.com/science/arti...

Thrilled that our work on integrating genetic, contemporary and traditional risk factors into acute MI models has been published in @CirculationGenomeandPrecisionMedicine @ahascience.bsky.social !! Are genetic and contemporary risk factors as powerful as traditional RFs? #CardioSky #cvPrev

Our study led by @romitb.bsky.social & C. Marnell shows that, when simultaneously considering clinical, laboratory, and genetic risk factors for incident CAD prediction, the top 2 model explanatory factors are: 1. Hypertension 2. CAD polygenic risk score www.ahajournals.org/doi/10.1161/...

Out today in AJHG, this work from my (recently graduated) student Teng Heng on recessive effects in 44k British South Asians from the Genes & Health project @genesandhealth.bsky.social . She found 185 independent hits of which >40% were novel. Worth looking for these in your own cohorts!

Our study led by A. Shankar shows that genotype-phenotype discordance of LDL-C (stronger polygenic predisposition to hypercholesterolemia for a given LDL-C) stratifies CAD risk - esp in normocholesterolemia. www.sciencedirect.com/science/arti... @jaccjournals.bsky.social #JACCADv

Direct-to-Consumer genetic testing for cardiovascular disease: A scientific statement from the AHA www.ahajournals.org/doi/10.1161/... Pragmatic overall. Patients are showing up to clinics with DTC genetics and we need to an approach to manage, ultimately leading to standards for the DTC industry.

Good to see a score-of-scores approach continuing to build better more stable PGS👇 We've widely used these methods (eg metaGRS/integrative PGS) at least since 2017-18... they rest on the ensembling principle for noisy predictions. Indeed many biomarkers are v noisy but not easily ensembled like PGS
