Molecular Life Extension

By Cynthia Forlini and Ainsley Newson

Alongside the question of whether we can treat ageing is the question of whether we should.

It is a universal certainty that we will all die one day. And we have a near-universal goal for our deaths to come painlessly after a long and full life.

Of course illness, disease and accident can cut life short. For many of us, however, our deaths will come as a result of growing old and our bodies gradually failing us.

But should we accept this biological status quo as the basis of our lives? Or is ageing something to rail against and try to defeat?

Ethical Challenges About Voluntary Assisted Dying

By Ian Haines

Much of the focus on new voluntary assisted dying laws is centred on patient autonomy, but it is only one of the four pillars. Does the legislation also satisfy the other three tenets of beneficence, non-maleficence and justice?

Will voluntary assisted dying (VAD) legislation provide compassionate physician-assisted dying, as hoped, or are we providing state-sanctioned euthanasia and assisted suicide? It certainly raises some important ethical questions.

Many of the submissions in Victoria were about tragic cases of desperate and suffering people with incurable illness who had taken or attempted to take their lives in sometimes very horrific circumstances. There was also a focus on high-profile celebrities and politicians who had watched on feeling helpless as a loved one suffered and died.

The Man with the DNR Tattoo

By Michael Cook

Should doctors follow the instructions of a tattoo when facing end-of-life decisions?

Doctors at a Florida hospital’s emergency department were startled to discover the words “DO NOT RESUSCITATE” tattooed on an unconscious man’s chest. The word “not” was underlined. Beneath this imperative was his signature, also tattooed.

“We’ve always joked about this, but holy crap, this man actually did it,” one of the doctors who treated him said. “You look at it, laugh a little, and then go: Oh no, I actually have to deal with this.”

Get Your Head Screwed on Right

By Michael Cook

Claims of the successful transplant of a human head may have been met by derision but they also reveal bioethical blindspots among ambitious surgeons.

What can you do if you become a quadriplegic after a catastrophic injury, or if you’re getting old, weak and fat? One solution is head transplantation – once the theme of very bad science fiction films and now the theme of press conferences.

Controversial Italian neurosurgeon Dr Sergio Canavero announced to media in Vienna recently that a team from Harbin Medical University led by his colleague Dr Ren Xiaoping has carried out the world’s first head transplant experiment. (In his line of business, they call it cephalosomatic anastomosis.)
