Have you been asked to review “TLS” bloods?? Are you concerned the nursing staff are pranking you with haematology bloods that don’t include a FBC or coags? Why could you possibly want to look at something that isn’t a cell count? What crazy person decided after hours bloods needed to be collected on ICE? And WHY ?!?!

It’s the heaviest matter of haematology as we look at the role of heavy metals in our favourite metalloenzymes. What - you don’t have a favourite metalloenzyme?  But nothing else matters?! Anyway, this is no esoteric surgical content, join us as Nick, Cale and Bashar get comfy with the weirder parts of the periodic table and how they apply to less common deficiencies or toxicities in haematology. Look we’ll be honest with you - this is pretty low yield listening but it was fun, and really isn’t that point at the end of the day. TIMESTAMPS0:55 - Wacken Open Air or Bloody Minded?3:58 - Molybdenum ft.

Is it a giant Cthulu-esque sea monster? Is it an excellent Australian parody breakfast show? No - it’s everyone’s favourite (well everyone who counts) coagulation related Vitamin - Vitamin K! Where does it come from? Why is it so hard to find on the eMR when you want to prescribe it and what is it doing under phytomenadione? Can we test for it?

‘This bad boy can fit so much iron in it’ he said slapping the roof of a badly photoshopped molecule of apoferritin superimposed on a car. Is too much ferritin bad for you? Of course it is - too much is precisely the quantity that is in excess. But most of the time hyperferritinaemia has nothing to do with iron overload. Strap in to your 1992 Honda Civic as the Bloody Minded Crew learn all about ferritin, and why most of the time too much of it has nothing to do with your iron levels at all.

It's a BONUS episode today as the Bloody Minded Crew are delighted to partner with the Thrombosis and Haemostasis Society of Australia and New Zealand (THANZ). After (correctly) exiling Nick to another country after he suggested yet more coagulation themed episodes, he's returned like Gandalf stronger and more powerful than ever. We cornered THANZ members at the International Society for Thrombosis and Haemostasis 2026 meeting to chat about what was keeping them interested.Special thanks to Dr Danny Hsu, Dr Sara Ng, Dr George Mason, Dr Angela Huang, Dr Ibrahim Tohini-Esfahani, Dr Emily Powley, Dr Catherine Neal, Dr Marc Ellis, Dr Charithani Keragala, Hadley Bortz and Danielle Boyle for their contributions.Check out the THANZ website (www.thanz.org.au) and consider signing up if you're an Australian based scientist, clinician, nurse or allied health professional with an interest in Thrombosis and Haemostasis.There will be no show notes for this episode and our regular programming will continue as usual. Support the showCheck out show notes, additional references and (sometimes) extra content at www.bloodyminded.com.au

Nick wanted to talk about buckets all episode. I’ve convinced him to at least let us get angry at iron polymaltose, hypophosphatemia and nangs all over again. You don’t think you need this episode but you’d be amazed how many consults come through to Haem thinking we’re the gatekeepers of iron in the building.

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.

So you’ve been asked to start a DOAC? How is that different from a NOAC? Is there a difference? Which one should you start? Is warfarin a WOAC? How do I initiate these drugs? Why is the dose weird at the beginning? Do I need to check my dose is appropriate? If oral anticoagulation has you discombobulated you are in the right place!! In part II on the practical management of anticoagulation we are here to clarify all your questions on the most common types of oral anticoagulation you will come across as a junior doctor on the wards.Timestamps1:44 - Part I Recap and Part II Introduction3:44 - History of Warfarin8:37 - Mechanism of Warfarin13:01 - Monitoring Warfarin16:52 - Why Warfarin? and warfarin tips21:40 - Warfarin reversal31:05 - Warfarin Skin Necrosis & Drug Interactions36:08 - Warfarin in Special Circumstances40:25 - DOACs Intro41:12 - Dabigatran48:25 - Anti-Xa Agents (Rivaroxaban / Apixaban)52:38 - Anti-Xa Monitoring (or not)59:28 - DOACS - Special Circumstances1:05:58 - WrapupSupport the showCheck out show notes, additional references and (sometimes) extra content at www.bloodyminded.com.au

Does my blood look fat in this?Does the idea of heparin being a fraction make you wish you listened harder in maths? What is unfractionated heparin? Why are haematologists so judgmental and prefer their anticoagulation low molecular weight? Why does haematology frown when you use the term “blood thinners” ?!?!If injectable or parenteral anticoagulation feels confusing you have come to the right place! Today we look at unfractionated heparin and low molecular weight heparin,  practical things to think about and how to manage these drugs safely on the wards and beyond NB We’re going to leave the advanced injectables like Fonda/Danaparoid/Bivalirudin to a dedicated alternative, probably HITTS themed episode if you’re looking for these drugsSupport the showCheck out show notes, additional references and (sometimes) extra content at www.bloodyminded.com.au

We’ve had one difficult coagulation topic yes, but what about second difficult coagulation topic? We are joined by the fantastic Dr Caroline Dix today to take us through not one but TWO challenging scenarios in thrombosis. First we’ll be revisiting Cerebral Venous Sinus Thrombosis but this time with someone who knows what they are doing. After that we’ll cover anticoagulating people when some very fundamental parts of the system are broken - the management of antithrombin deficiency.

Sometimes something comes along that puts a chill down the spine of every doctor. Any conversation that starts with "Oh hey do you remember that patient you saw...?". Mystery meat day in the cafeteria. Dealing with hospital executives. For these times in life you need a guide. Today we'll be covering one of those spine-chilling clinical scenarios with our very apt guide consultant haematologist Dr Sara Ng. Over forty minutes Sara will un-chill your spine with her practical approach to managing thrombosis when there just aren't that many platelets to go around, as well as talking about conditions where clots and thrombocytopenia are intimately linked.Timestamps: 2:11 - Introducing Dr Sara Ng7:18 - Case 1: Acute PE and Thrombocytopenia14:55 - Case 1.5: Subacute PE and Thrombocytopenia18:20 - Case 2: Line Thrombus during Chemotherapy22:09 - Thrombosis in ITP26:15 - Oh no a STEMI27:44 - Two sides of the same coin31:58 - How 2 4T Score - HITS35:15 - Other PF4 Antibodies38:33 - Wrap up & TakehomesSupport the showCheck out show notes, additional references and (sometimes) extra content at www.bloodyminded.com.au

The mighty eosinophil had triumphed. The last parasitic worm lay vanquished beneath his granule-studded pseudopodia. For years, he’d battled helminthic scourge, a hero in mucus armor. But now, with no foes left to smite, he grew restless. He turned his sharp gaze to pollen, peanuts, and pet dander. "Troublemakers," he muttered, unsheathing his cytotoxic arsenal. With righteous zeal, he charged into the sinuses and skin, sparking sneezes and wheals in his wake. “A threat is a threat,” he declared, as a baffled immunoregulatory system looked on. The worms were gone - but the war had only just begun.
