In the previous episode we heard how some rationally-designed therapies work on almost any cancer with the right molecular signature. Tumour-agnostic medications could be godsend for patients with rare cancers which have classically been overlooked by drug developers, and those with advanced cancers of unknown origin. 15,000 such patients have undergone comprehensive genome profiling of their tumours through the organisation, Omico. In this podcast, Omico’s founder explains that while the majori...
Jan 28, 2025•50 min•Ep 122•Transcript available on Metacast The genomic understanding of cancer has transformed a tissue-based classification model that had been dominant for 150 years or more. The last three decades have seen highly targeted therapies developed at blistering pace, and unprecedented improvements in patient outcomes. To date, these advances have been focused on more common cancers. The financing model for drug development means that rare cancers get overlooked, given the small pool of potential buyers relative to the costs and risks of in...
Jan 16, 2025•47 min•Ep 121•Transcript available on Metacast This case report describes a 35-year-old Caucasian male presenting with 5 weeks of progressive weakness in the proximal limbs and trunk and associated changes to the skin. The man was previously well and not taking any regular medications. There are many pathways this undifferentiated patient could go down. Consultant physician, Professor Josephine Thomas demonstrates a systematic way to work through the differential diagnoses as would be expected in a long-case presentation for basic physician ...
Dec 19, 2024•30 min•Ep 120•Transcript available on Metacast In 2019 a man was referred to Royal Adelaide Hospital with worsening breathlessness and a productive cough. He was a 47 year old electrician with a history of tobacco smoking who’d been well before the onset of symptoms. Over a couple of admissions the patient’s condition progressed to type 2 respiratory failure. While the ultimate explanation for this presentation was a bit of a unicorn, the dramatic escalation of examinations and interventions runs through some textbook respiratory medicine; E...
Nov 20, 2024•34 min•Ep 119•Transcript available on Metacast Thrombectomy for acute ischaemic stroke has undergone great advances in the last decade, but the expertise and technology is restricted to tertiary hospitals. Outside of large metropolitan centres, thrombolytic treatment can buy a patient time, but for almost 30 years the first line agent has remained unchanged. Alteplase is an analog of the human tissue plasminogen activator which activates plasmin to dissolve fibrin blood clots. For many years it was assumed that alteplase should be administer...
Oct 24, 2024•43 min•Ep 118•Transcript available on Metacast This podcast follows the case of a 48-year-old male with a 3-month history of diarrhoea and associated lymphadenopathy. A complex constellation of symptoms accompanies this presenting complaint, along with a key radiological finding that enabled the treating team to arrive at the correct diagnosis. Can you arrive at the correct diagnosis before the treating team? This case was managed at the Queen Elizabeth Hospital and is presented by Dr Andrew Vanlint from the Northern Adelaide Local Health Ne...
Oct 10, 2024•25 min•Ep 117•Transcript available on Metacast This recording comes from the launch of the 2nd Monitoring and Evaluation Report on Hepatitis C Elimination in NSW. The work was conducted through the Kirby Institute under the guidance of infectious diseases specialist, Professor Greg Dore. As presented in this seminar, data show that the state is on track to meet the 2025 target set by NSW Health, and the national target for 2030, but there have been surprises along the way that have required an adaptable approach to surveillance and intervent...
Sep 19, 2024•34 min•Ep 116•Transcript available on Metacast Dr Karan Singh loves his job as a registrar in nuclear medicine but he thinks there isn’t enough exposure to the specialty during medical school and basic training. In this podcast we spend a day in his department at Prince of Wales Hospital Sydney and get a taste of the many different referrals that come his way; a bone scan for a young man experiencing leg spasms after recovering from a car crash; myocardial perfusion imaging for an elderly gentleman with coronary artery disease; staging for p...
Sep 09, 2024•44 min•Ep 115•Transcript available on Metacast The LACE index is a prognostic algorithm for predicting the likelihood that a newly discharged patient will come back into hospital within 30 days because of complications. Today’s IMJ paper describes a validation of the LACE index in a regional Victorian setting. Identifying patients who are at risk could allow for better targeted care at the first admission, reducing harm to patients and inefficient use of healthcare resources. The researchers also tested a novel classification tool for scorin...
Aug 22, 2024•31 min•Ep 114•Transcript available on Metacast This podcast follows the case of a 58 year old man who presented to the haematology department at Flinders Medical Centre with intravascular coagulation and leukocytosis. He was diagnosed with acute myeloid leukaemia and treated on standard cytarabine and daunorubicin combination therapy. Nine days after initiation, the patient developed painless diplopia and ptosis, and the story is picked up with a referral to the neurology department. Guests Associate Professor Stephen Bacchi (Lyell McEwin Ho...
Aug 09, 2024•25 min•Ep 113•Transcript available on Metacast The RACP Congress in May this year was opened by a fascinating lecture on mental health in the medical workforce, which has been trimmed down for audio. Professor Neil Greenberg is an occupational psychiatrist with more than 23 years in the UK Armed Forces. His extensive research within defence and health settings has informed a very pragmatic understanding of the impact of trauma and relationships in the workplace. Professor Greenberg overturns some entrenched beliefs we have about the presenta...

Jul 16, 2024•16 min•Ep 111•Transcript available on Metacast This case report has been developed by Trainees, to assist their peers with preparation of long-case presentations. It is not a fully-vetted Education resource but a “passion project” from editors of the Pomegranate Health podcasts. The case is that of a 32-year-old woman presenting with constant and dull abdominal pain that had been sudden in onset. The pain is accompanied by nausea and vomiting but bowel habits were unchanged. The patient has a history of type 1 diabetes and a simultaneous pan...
Jul 03, 2024•21 min•Ep 110•Transcript available on Metacast Australia is a big continent and sparsely populated continent. 28 percent of Australians live in areas classified regional, rural or remote and their access to health services is much more limited. It’s estimated that between 2009 and 2011 there were 19,000 excess deaths in regional and remote areas as compared to the major cities. No doubt, socioeconomic disadvantage is factor in that mortality gap, but inequitable access to healthcare is also a major driver. In this podcast we focus specifical...
Jun 11, 2024•46 min•Ep 109•Transcript available on Metacast Pomegranate [Case Report] is a Q&A style podcast developed by trainees, for trainees. In our debut episode, we hear about w a who man presented to the emergency department reporting sudden onset vision loss in his right eye lasting several hours. He was 68 year old with a history of type 2 diabetes mellitus. Three differential diagnoses being considered were optic neuropathy, vitreoretinal disease, or corneal oedema following from potential uveitis. In this podcast consultant ophthalmologist...
May 15, 2024•32 min•Ep 108•Transcript available on Metacast Type 1 diabetes has a very high treatment burden in terms of direct costs, inconvenience and lost productivity for patients and their carers. Further, all the glucose checking, hormone replacement and consults don’t abolish the vascular complications associated with poor glycaemic control. Only in the last few years has it been possible to pharmacologically alter the course of type 1 diabetes and other auto-immune diseases without generating intolerable side effects. Teplizumab is an antibody to...
Apr 11, 2024•41 min•Ep 107•Transcript available on Metacast Today’s guests are the hosts of This Medical Life , a wonderful podcast that delves into the archives of medical history. Dr Travis Brown describes the period after World War I when the Spanish Flu was killing tens of millions around the world. In the USA, whiskey was thought to be a powerful prophylactic but distribution was not an easy thing. Later in the episode (22min) is the equally unlikely tale of how the pomegranate made its way from ancient myth onto this podcast by way of Henry VIII an...
Mar 25, 2024•31 min•Ep 106•Transcript available on Metacast Last November an NHS Hospital Trust in Nottingham sought permission from the UK High Court to withdraw life support from a seven-month old girl called Indi Gregory. The devastated parents did not want to give up on her although they were advised there was no hope of treatment for her profound developmental disability. The family and the medical teams returned to court two more times, right up to the day that Indi was to be extubated. Conflicts over care have always existed but their frequency ha...
Feb 26, 2024•49 min•Ep 105•Transcript available on Metacast The theory that certain fatty acids are essential to the diet and associated with reduced cardiovascular risk has been controversial since it was floated in the 1950s. In 1971 Danish researchers published the results from a cross-sectional study of Inuit people living on the west coast of Greenland . They ate a fish-based diet rich in polyunsaturated fatty acids known as omega-3s, which were found in their tissues along with much lower levels of pre-β-lipoprotein and plasma-triglycerides when co...
Jan 30, 2024•26 min•Ep 104•Transcript available on Metacast Median survival for patients diagnosed with advanced cirrhosis is around 2 years and quality of life is poor. Fewer than a quarter of such patients receive referrals to palliative care and advanced care plans are also rare. Existing research from abroad suggests that hepatology staff aren’t familiar with referral criteria and assume that palliative services become involved only at the very end of life. To try and reduce barriers to referral, clinicians at Royal Brisbane Hospital developed a mode...
Dec 11, 2023•40 min•Ep 103•Transcript available on Metacast Semaglutide, branded as Ozempic or Wegovy, is an analogue of glucagon-like peptide 1 which has glucose-dependent effects on insulin secretion. In this episode we discuss how semaglutide performs as an antihyperglycaemic agent compared to previous GLP-1 analogues and the soon-to-be launched tirzepatide. This dual agonist also binds receptors to glucose-dependent insulinotropic polypeptide, GIP. GLP-1 and GIP are incretin hormones, secreted after food intake and involved in regulating gastric moti...
Nov 13, 2023•55 min•Ep 102•Transcript available on Metacast We’ve known for a decade that about 50 percent of doctors meet the criteria for burnout, and the figure is up to 70 percent among trainees. But organisations have been left to come up with their own solutions to this, the result being that many simply offer band aid solutions rather than systemic ones. Unforgiving work conditions pose a problem for both recruitment and retention of staff to the health workforce. The New Zealand Health Department, Te Whatu Ora, forecasts that within ten years sup...
Sep 26, 2023•56 min•Ep 101•Transcript available on Metacast This is the final episode in a five-part series about artificial intelligence in medicine. We start by weighing up the costs and benefits of automation in a health system that’s increasingly pushed beyond capacity. One of the biggest time sinks for health practitioners is filling out and searching through medical records. Some of this could be performed by natural language processors which are becoming more accurate thanks to deep learning. The power of large language models has been demonstrate...
Aug 16, 2023•37 min•Ep 100•Transcript available on Metacast This is the fourth part in a series on artificial intelligence in medicine and we try and unpick the causes and consequences of adverse events resulting from this technology. Our guest David Lyell is a research fellow at the Australian Institute of Health Innovation (Macquarie University) who has published a first-of-its kind audit of adverse events reported to the US regulator , the Federal Drugs Administration. He breaks down those that were caused by errors in the machine learning algorithm, ...
Aug 09, 2023•39 min•Ep 99•Transcript available on Metacast On the 28th of January 2022 a 75-year-old man was admitted to the regional Albury Wodonga Health Service with a high fever and Parkinsonian symptoms. The patient spent over a week in intensive care, but brain scans did not reveal an obvious aetiology and assays for a range of pathogens came up negative. When serology eventually revealed the presence of antibodies against Japanese encephalitis virus this became only the second ever locally-acquired case on Australia’s mainland. Even more startlin...
Jul 16, 2023•44 min•Ep 98•Transcript available on Metacast This is the third part of a series on artificial intelligence in medicine. Previously we explained how to train and test machine learning models that assist in decision-making, and then how to iron out ergonomic friction points in the clinical workflow. We’ve mentioned how deep learning neural networks are more capable than classical models at dealing with big noisy data sets, but also that the reasoning they use to solve questions asked of them might be inexplainable users. This creates a certa...
Jul 05, 2023•34 min•Ep 97•Transcript available on Metacast The allure of having devices and tasks assisted by artificial intelligence is that they will help overcome some of the natural limits of human cognition with regards to working memory and attention. And in helping with the mundane tasks, AI can buy clinicians back time to spend with the complex patients who really need it. But the way all this pans out will really depend on how seamlessly the machine learning devices fit in with the clinical workflow. Which aspect of clinical decision-making do ...
Jun 21, 2023•42 min•Ep 96•Transcript available on Metacast AI-assisted healthcare is reaching maturity in many applications and could alleviate some of the capacity gap increasingly faced by health systems . Over the next three podcasts we focus on artificial intelligence tools designed to assist directly with clinical practice. Most commonly reported on are the algorithms capable of pattern recognition on medical images, that in some settings perform as well or better than expert diagnosticians at classifying disease. AI models have also been developed...
Jun 14, 2023•38 min•Ep 95•Transcript available on Metacast In today’s podcast we try and understand the impact that racial bias makes on variation in clinical care. For example, racialized patterns in the use of analgesia were brought to light over 20 years ago but are still occurring today. In research from the UK published in March it was found that women of African or South Asian extraction were significantly less likely to receive an epidural during vaginal birth, or instrumental assistance with the delivery. The direct reasons for this variation we...
May 12, 2023•59 min•Ep 94•Transcript available on Metacast The first time most of us heard of monkeypox was in May 2022. The smallpox-like infection appeared to spring from nowhere and make its way through Europe then the Americas, largely within the gay and bisexual community. But the first documented human case of mpox actually occurred in 1970 in Central Africa and it’s been endemic ever since. Last year’s mpox outbreak eclipsed prior case numbers in just a few months thanks to a newly evolved strain. The count of confirmed cases totalled over 86,000...
