Super proud of my wife, @Rsk2003, for presenting our work on ICI-ITP at @ASH_hematology! Our paper also came out today in #BloodJournal (doi.org/10.1182/blood.202503…). Very grateful to all of our wonderful collaborators who made this possible!

Does Vitamin D protect against kidney injury? Here, @waikarss @DavidLeaf9 & team @BrighamWomens conduct a phase 2, randomized, double-blind, multi-dose, 3-arm clinical trial in critically ill adults. While treatment with calcifediol or calcitriol upregulated genes in several pathways and had anti-inflammatory effects, it did not prevent acute kidney injury: insight.jci.org/articles/vie…

Huge thanks to @waikarss, @EdyKim5, and @NIDDKgov, without whom this would not have been possible.
In a new study, researchers from @MGBKidneys and colleagues investigate vitamin D and acute kidney injury prevention. The study was published in @JCI_insight. Read more: insight.jci.org/articles/vie… @DavidLeaf9

Happy Miracle on Ice Day if you’re observing it. 45 years ago today, February 22, 1980, a bunch of hard-nosed American college kids beat the seemingly invincible Soviets at 1980 Winter Olympics in Lake Placid, NY. “Do you believe in miracles? Yes!”

Thrilled to share that an article I co-authored with @ShrutiGkidney and @DavidLeaf9 from Brigham and Women’s Hospital is now published in Blood! We demonstrated the efficacy of glucarpidase for mitigating high-dose methotrexate toxicity. Read more here: ashpublications.org/blood/ar…

Is kidney biopsy the only way to diagnose immune checkpoint inhibitor-associated acute kidney injury (ICI-AKI)? Maybe not. In a new paper in @jclinicalinvest , @DavidLeaf9 and I report that PET-CT may have a role. A brief #tweetorial #Thread (jci.org/articles/view/182275).
