Platelet immunology SSC at @isth standardizing HIT and VITT testing

the McMaster Platelet Immunology Lab is a 2021 recipient of the @McMasterU President’s Awards for Outstanding Service in the Team Award category! kudoboard.com/boards/2VgMLHZp @MacDeptMed @MacPlateletLab @Mac_Transfusion @McMasterIIDR @MacGlobalNexus @machealthsci @fordnation

@McMasterScience @Avis_Favaro @McMasterU What an exciting opportunity for us. @Avis_Favaro please connect and we can tell you what it was like to discover the mechanism of the vaccine clotting syndrome @IshacNazyPhD @MacPlateletLab and led the Canadian convalescent plasma trial @Mac_Transfusion @CONCOR1Trial

Award-winning health journalist @Avis_Favaro will be the first journalist in residence at @McMasterU's Faculty of Science this fall. Avis will spend 4 weeks on campus meeting with faculty, postdocs & students, with the learning going both ways. linkedin.com/feed/update/ur…

Therapeutics are here and continue to come down the pipeline. They won't solve ongoing community transmission, but systems to support their use will help with ensuring our highest risk populations have benign outcomes. We need to step up. theglobeandmail.com/opinion/articl…

Very proud moment to have John Vrbensky successfully defend his PhD thesis @MacPlateletLab @Mac_Transfusion @arnolddma1 @PatriciaLiaw

@erica_m_wood Thanks @erica_m_wood. Turns out VITT antibodies bind to the same spots on PF4 as heparin. Explains why VITT antibodies cause ‘HIT’ without the heparin. Clever idea by @ishacgaby and thanks to the support of @machealthsci @Mac_Transfusion @PHAC_GC

Something special being in the @TheSpec. I’m Hamilton born and bred and @McMasterU educated, trained and employed. ‘Nature’ fast-tracks publishing McMaster’s research on vaccine-induced blood clots - thespec.com thespec.com/news/hamilton-…

Congrats @McMasterU Platelet Immunology Laboratory for outstanding research on how Vaccine-Induced Immune Thrombotic Thrombocytopenia (VITT) is triggered, opening pathways to explore prevention, treatment & improved vaccine safety. twitter.com/McMasterU/stat…

For all my Lab Peeps — See below for a great opportunity to work in the internationally recognized Platelet Immunology Lab @McMasterU with @MacDeptMed @ishacgaby @Mac_Transfusion @arnolddma1 and many more ... if interested please contact @medlabmaria @ishacgaby

Launch of Ontario's Massive Hemorrhage Protocol recommendations via @ORBCoN1 today! Several years of work, lead by Drs @JeannieCallum & Katerina Pavenski. Amazing provincial effort that will undoubtedly improve care of bleeding patients in Ontario! transfusionontario.org/en/category/ma…

MY GOODNESS OG

Dr. Samir Gupta explains how the four COVID-19 vaccines now approved in Canada work and why efficacy rates aren’t the most important number to look at.

Uber-smart ⁦@MacDeptMed⁩ Dr. Donnie Arnold describing RARE AZ vax side effects ⁦@CTVNews⁩ Bottom line: benefits >>> risks 👍🥳🇨🇦

@zchagla Thanks @zchagla! So many people came together to make this happen including @CanadasLifeline @HemaQuebec @NYBloodCenter, patients and plasma donors. 🙏

Fanastic work to @arnolddma1 and others for making this made in Canada trial happen. Unfortunately, no benefits seen in the population receiving plasma. Very thankful for organizations who went above and beyond to prove effect, rather than allowing for off-label use.
