On the Ning Nang Nongs where the youths smoke bongs and the marrow all screams HELP! Join the Bloody Minded crew as they go through the round window, follow B12 and folate around the body in a Nang induced haze, presumably just like the writers on Play School once were.

Heal with steel? Absolutely not - There’s no alloys or for that matter surgeons allowed in the safe space of the laboratory. Join us on another wonderful lab adventure as Bashar, Cale and Nick head down to the biochemistry lab to work out exactly how our iron studies are performed in the lab before you throw the serum iron in the bin.

Taunted by transferrin? Befuddled by ferritin? Scratching your head at why we throw the serum iron results directly into the confidential waste bin, which is a more dignified burial than it deserves? Come along as the boys discuss the interpretation of iron studies in a definitely tight, definitely 20ish minute episode.

One molecule to rule them all, one molecule to find them. One molecule to bring them all, and in the liver bind them. Hepcidin is the key to understanding iron metabolism and we examine how iron gets into, around and out of the body. We promise not to be too Celebrimbor-ing as you join Nick, Cale and Bashar  for this discussion of the basic science of iron handling in preparation for our journey into the building blocks of blood. Welcome to Lord of the Haematinics.

Has your ward team been hit with HITT? Is Jane the only Fonda you know? Is BAD an 80s hit and not a trio of anti-coagulation infusions (Bivalirudin, Argatroban and Danaparoid). Is Alison showing her age? Never fear; join Alison, Bashar, Nick and Cale as they aim to de-mystify less commonly used anticoagulation that may come up on the wards.

This week we continue the pattern of guests who are really really ridiculously good at haematology and also really really ridiculously nice people as well. We are very excited to be joined by Dr Michael Krigstein who many of you would know as the a molecular haematology guru who has gotten countless patients through their diagnoses and countless haematology trainees through their exams.

What happens when you take someone who is really really ridiculously good at haematology and also a really really ridiculously nice person as well? You get Dr Jad Othman, consultant Haematologist and Haematopathologist at Royal North Shore Hospital in Sydney who will be joining us today to discuss the use of measurable residual disease in acute myeloid leukaemia.

Dr Othman is well suited to this topic, having written his doctoral thesis on molecular disease assessment in AML, sitting on the European LeukaemiaNet (ELN)-DAVID MRD Working Group as well as numerous ALLG AML and MDS working groups. We're delighted to have him field the Bloody Minded Crew's questions today.

Here’s a question, what do CD123, CD4 and CD56 have in common? Other than pleasing The Count on Sesame Street. Sorry, another question perhaps - what happens if you cross a plasma cell and a dendritic cell? The answers to these questions can be found on a most enigmatic myeloid cell - the plasmacytoid dendritic cell. And what happens when these rare beasts become neoplastic - why BPDCN of course. Embark on a journey into this weird and not so wonderful (but highly examinable) neoplasm with the Bloody Minded Crew

“It’s pronounced nuc-ul-ophosmin” “Nucleophosmin”. “Noo-clee-o-phosmin”. FLT3-ITD got you In The Dumps? Have a Total Knowledge Deficit about TKD mutations? Struggling with the A-B-Cs of NPM1 mutations? Want to know how a cat sarcoma is somehow related to AML? Join the Bloody Minded Crew as they flit about the laboratory looking at the structure of FLT3 and NPM1, what these proteins usually do and how we test for mutations in the advanced myeloid episode.

== Edit 6/5/26 = We've been made aware that strictly speaking the current MANE approved transcript for NPM1.1 has only 11 exons and therefore the mutations are best to be considered in Exon 11 as opposed to exon 12 - in contrast to what we said. ==
