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.

Ep141: Space Medicine Part 2- really remote practice
The record for the longest space-flight is held by physician-cosmonaut Valeri Polyakov. Back in 1994-95, he spent 437 days on the Mir space station and grew 4 centimetres in height through elongation of his spine in micro-gravity. Polyakov had an uncomfortable ride back to Earth in the very precisely customised descent module.
Microgravity also causes demineralization of weight-bearing bones that is faster than age-related decline. But the cosmonaut had worked out religiously for the entire mission and after his capsule parachuted to the ground he made a point of walking from it relatively unassisted. One of the main objectives of the marathon flight had been to prove that walking proudly onto the Martian surface after a 9-month journey might be possible, given it only has 37 percent the gravitational force that Earth does.
Microgravity additionally results in adaptive plasticity of the vestibular and sensorimotor networks and deconditioning of the cardiovascular system. Indeed, several years ago there was a medical emergency aboard the international space station when an ultrasound investigation revealed thrombosis of the internal jugular vein in one astronaut. In this podcast we discuss how management of cases like this has many parallels with remote medicine on earth. Part 1 of this series examined the risks of cosmic radiation and spaceflight-associated neuro-ocular syndrome among other things.
