🔥Tweetorial Alert 🔥 🍩Donut Hole and Medicare Part D. What does that mean? Why should I care as a physician? ⬇️is a tweetorial on Medicare Part D and donut hole. 📌Disclosure: all donuts taste good but this one is bitter!
No one better than @NadaAlachkar @hopkinsneph 2 learn from about FSGS & kidney transplant. Great grand rounds @MayoClinic Arizona! FSGS post-transplant remains a challenge. Better phenotyping based on permeability factor is key & hopefully we’ll have that capability in coming yrs


Three years at @MayoClinic today. Grateful for the incredible colleagues, meaningful work, and the privilege of caring for #transplant patients every day. Here’s to continued growth and impact.

What to expect on a xenograft kidney pre implant biopsy: 📌 IF: mesangial immune complex deposits in all 3 grafts likely donor-related 📌 EM : - Intact podocyte foot processes - Thin GBM vs human glomeruli likely normal porcine anatomy

Do non HLA antibodies matter in #transplant?

We are thrilled to welcome our incoming General Nephrology fellows! Welcome Dr. Brown and Dr. Lopez. We look forward to seeing all of your amazing accomplishments over the next two years of fellowship!
Kidney disease affects 1 in 8 people, and early detection saves lives. Proud to support @NKFArizona and all the amazing volunteers making screening possible!

Excited to work with these 2 excellent trainees.
As we wrap this academic year and start a new academic year, I am excited to welcome our incoming Nephrology fellows; Dr. Brown and Dr. Lopez! I also look forward to meeting our future applicants in the next interview season! Summer is an exciting time for medical educators!!!

Our new study from NW Syria about ESKD patients perspective about their care. 29% missed sessions, 60% were displaced, health literacy is low, and many lacked access to nephrologists. Low-resource solutions are urgently needed. bmchealthservres.biomedcentral.com/articles/10.11…
An exciting advancement in minimally invasive transplantation @MayoTransplant in AZ! Looking forward to the impact on perioperative outcomes and broader clinical practice. @CarrieJadlowiec @SamiAlasfar @aqel_bashar @nnk_tx_hpb @StephOharaMD
Congratulations to our @MayoTransplant team at @MayoAZSurg on performing our first robotic kidney transplant! The team was led by @MCNguyenMD, @CarrieJadlowiec, #NitinKatariya, and @StephOharaMD. They have since done 3 more, and we look forward to more to come!

Exciting competition is heating up in our transplant center! The talent of drawing is truly impressive. Proud to be part of a team that continuously raises the bar! @MayoTransplant @MCTransplntSurg @MayoClinic #Arizona #Kidneywalk #liverwalk #heartwalk #lungforcewalk

Another colleague I’m incredibly proud of! Congratulations, Dr. Khamash!
frontiersin.org/journals/nephr… Higher donor eGFR was associated with lower risks of graft loss and patient death in the HLA-DR mismatch group but not the 0 HLA-DR mismatch group. These results emphasize the importance of considering both HLA-DR matching and donor kidney function,…
