Dear TTS Membership,

I recently have taken over as Chair of the Ethics Committee and I am very pleased to update TTS membership on committee activities.

The membership of the Ethics Committee has been renewed recently and I am delighted to say that there is great expertise and breadth of knowledge across the group. You can see membership below:

  • John Forsythe, United Kingdom
  • Peter Stock, United States
  • Riadh Fadhil, Qatar
  • Mario Filho, Brazil
  • Brendon Parent, United States
  • Alicia Perez Blanco, Spain
  • Carrie Thiesen, United States
  • David Thomson, South Africa
  • Kristof Van Assche, Belgium
  • Anji Wall, United States

I am also pleased to report that there is quite a lot going on in the committee at present. With huge thanks to the previous chair of the committee, Peter Stock, there are three projects which are nearing completion.

Brendan Parent has been leading this and members will soon see a publication on the ethics of xenotransplantation which is, of course, highly topical.

Transplantation in migrants and refugees
Peter Stock, with colleagues, continues to develop this project - once again this issue is very topical and one which has excited significant discussion alongside the DICG at the TTS2022 congress in Buenos Aires.

First person consent for imminent donation
Transplantation from donors in these circumstances is highly variable from nation to nation. Kristoff Van Assche is leading the project on review of the ethics in this area

Donation when death is diagnosed after circulatory arrest (DCD)
There is a planned project on this topic in conjunction with the Education committee, drawing on expertise from the ethics group to design a collaborative educational event. I am grateful to David Thomson for leading on this from the Ethics Committee.

Abdominal Normo -thermic Regional Perfusion and Thoraco-abdominal Normo-thermic Regional Perfusion
Again, this is an area of innovation in donation and transplantation which has a very variable footprint in different nations. Anji Wall has kindly agreed to take forward a project in this area and further details of this will be available in the near future.

Consent in donation and in research at the time of donation and transplantation
In many ways one would expect that this issue would be fully developed over the many years of clinical practice but with new techniques and with expectation and importance of research, it is correct that we continue to debate the issue of consent. I am grateful to Farrah Raza and colleagues in taking this project forward.

Hopefully members can see that the committee is working hard in their interests and I hope that we will be able to deliver useful and impactful products in all of these projects.

If members have any issues that they would wish to write to us about then please feel free to do so. Please write to Jennifer Groverman, in the first instance
