The globe has already warmed by more than one degree Celsius over pre-industrial levels and is on track to exceed two degrees by the end of the century. It doesn’t sound like a lot but this will have profound effects on human health with Australia being particularly vulnerable. Most obviously, Australia’s biggest cities will become furnaces in summer with a more than doubling of heat-related mortality. The rising temperatures will also increase frequency of the climate oscillations that delivered us record-breaking temperatures and bushfires in 2019-2020, followed by historic rains and floods last summer.   In this podcast we discuss the effects of this increasingly volatile climate on the health of Australians, from infectious disease to respiratory and even mental health. Professor Lynne Madden explains how the health system can become more resilient to these demands and what measures the RACP is asking Federal Government to commit to in preparation for this.  Find out more about the "Health Climate Future" campaign here.   Guest

Ep80: Healthcare in a Volatile Climate

Pomegranate Health is an award-winning podcast about the culture of medicine, from the Royal Australasian College of Physicians. We ask how doctors make difficult clinical and ethical decisions, how doctor-patient communication can be improved, and how healthcare delivery can be made more equitable.&nbsp;

This is also the home of [IMJ On-Air], a podcast to accompany the RACP's Internal Medicine Journal.&nbsp; Interviews with authors are conducted by specialist section editors. Find out more at the website www.racp.edu.au/podcast and get in touch via the address podcast@racp.edu.au

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 CD3 which was presented to the world in 2019 as delaying the onset of type 1 diabetes in high-risk individuals thanks to its protective effect on pancreatic β-cells. It has not yet been registered by the Therapeutic Goods Administration but another immunomodulatory drug called baricitinib has. Baricitinib is an inhibitor of Janus Kinases indicated for the for the treatment of rheumatoid arthritis, alopecia areata, atopic dermatitis and even COVID-19. 
 
In December of last year the results of a Phase 2 trial in patients with new-onset type 1 diabetes were published in the New England Journal of Medicine. After almost a year of taking the oral therapy, patients were found to have better glycaemic control and evoked C-peptide levels than those taking placebo, indicating a preserved ability to secrete insulin. In today’s episode, Pomegranate’s in-house endocrinologist interviews two of the study authors.

[Journal Club] Baricitinib immune therapy for new onset type 1 diabetes

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 and some mystical symbolism. Guests Dr Travis Brown MBBS, FRCPA (ClinPath Pathology)

Ep106: The whiskey fix and the apple of Granada

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 has increased as medicinal advances present more options for intervention even in the sickest patients. Added to that, the online media environment allows advocacy campaigns to grow until they spill onto the streets outside hospitals and courtrooms.  This heightened tension causes moral injury both to parents and healthcare staff looking after child patients. The Medical Mediation Foundation has developed a conflict management framework to help avoid or de-escalate such disputes and keep attention focused on the best interests of the patient. In this podcast we hear from the director of the foundation, as well as three staff from the Starship Hospital, Auckland who have undertaken this training.

Ep105: When parents and paediatrics clash

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 compared to controls. 
 
 That association between a fishy diet and lowered cardiovascular risk has been replicated in multiple population studies since then and there are several ways omega-3 fatty acids could mediate the effect. They have anti-inflammatory and antithrombotic properties, lower circulating triglyceride concentrations and keep vessels impermeable to plaque forming lipoproteins. For many years now clinical guidelines like those of the American Heart Association and the National Heart Foundation of Australia have explicitly encouraged dietary intake of omega-3s fatty acids for those at high cardiovascular risk. But such recommendations come despite considerable inconsistency in the outcomes from intervention studies on omega-3 supplementation over the past 25 years. From several large RCTs there have been just as many negative or neutral associations as there have been positive ones. Professor Christian Hamilton-Craig has published a viewpoint review in the December edition of the Internal Medicine Journal attempting to explain these inconsistencies.

[IMJ On-Air] Is the jury still out on omega-3 supplementation?

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 model called Hepatocare. They adapted a palliative care referral algorithm to include cirrhosis specific markers and continuity of care between the teams was provided by a clinical nurse consultant. The model was piloted model in 30 consecutive patients to the liver clinic, and its impact was assessed on rate of referrals, incidence of unplanned admissions, length of patient stay and rates of polypharmacy.
