Pomegranate Health
Pomegranate Health is a podcast about the culture of medicine. You'll hear insights from clinicians, researchers, and advocates as they tackle important questions — like how to make difficult clinical and ethical decisions without being influenced by bias, how to communicate better with patients and colleagues, and how to provide healthcare that’s both efficient and fair.
If you're a Fellow of the RACP, time spent listening can be counted toward your CPD hours. And if you're a Basic Physician Trainee, the [Case Report] series can help you prepare for your long case clinical exams.
This is also the home of [IMJ On-Air], featuring authors from the Internal Medicine Journal sharing their latest research. The [Journal Club] episodes give RACP researchers a space to talk through their work published in other academic journals. And for Basic Trainees, the [Case Report] series can help you prepare for your long case clinical exams.

Ep140: Space Medicine Part 1- radiation and retinopathy
In 2027, NASA’s is planning to land astronauts on the moon for the first time in 53 years with the expectation that there will be a permanent base there by the early 2030s. And the ever-humble Elon Musk reckons he’ll be sending people to Mars by then too.
This has prompted a renewed interest in the prolonged effects of space travel on the human body, and a lot of fascinating research has been conducted aboard the International Space Station over the last two decades.
The main objective risk to astronauts is exposure to galactic cosmic radiation. This can be reduced to some degree by shielding of space habitats, however, the impacts of microgravity are much harder to engineer away. In part 1 we’ll discuss spaceflight associated neuro-ocular syndrome and other sensorimotor impacts. In part 2 we’ll focus on the effects of microgravity on bone density and the circulatory system.
We’ll also talk through the management of a cases of suspected thrombosis on the international space station from a few years ago. Medical care on orbit has many parallels with the remote medicine you’re already familiar with.
