Face Transplants: An International History.

ABSTRACT: Face transplants have attracted global media and public attention since the 1990s. The first recipient, Isabelle Dinoire, found herself at the centre of a dramatic episode of surgical innovation after her transplant was announced in November 2005. Subsequently 47 transplants have been conducted worldwide (including two retransplants) up to August 2020, and these have been accompanied by extensive news coverage. Hundreds of papers on the medical, physical, psychological, and ethical implications of the procedure have been published in the scientific literature, disproportionate to the incidence of the procedure. Face transplants have also featured in films, television, and fiction, indicating an appetite for interrogating the social and interpersonal implications of facial difference. However, the history of facial transplantation has largely been unexplored. This article provides the first international history of the global development and implementation of facial transplantation. Using published medical literature, media coverage, and oral history interviews with key participants as source material, it situates the experimental transplant in national, institutional, and professional contexts. It argues that charting the history of face transplants over a 30 year period from initial discussions in 1991 to the present provides a valuable case study through which to consider surgical cultures and discourses of medical innovation in the twenty-first century.

Project description:ObjectiveTo develop and validate an integrative system to predict long term kidney allograft failure.DesignInternational cohort study.SettingThree cohorts including kidney transplant recipients from 10 academic medical centres from Europe and the United States.ParticipantsDerivation cohort: 4000 consecutive kidney recipients prospectively recruited in four French centres between 2005 and 2014. Validation cohorts: 2129 kidney recipients from three centres in Europe and 1428 from three centres in North America, recruited between 2002 and 2014. Additional validation in three randomised controlled trials (NCT01079143, EudraCT 2007-003213-13, and NCT01873157).Main outcome measureAllograft failure (return to dialysis or pre-emptive retransplantation). 32 candidate prognostic factors for kidney allograft survival were assessed.ResultsAmong the 7557 kidney transplant recipients included, 1067 (14.1%) allografts failed after a median post-transplant follow-up time of 7.12 (interquartile range 3.51-8.77) years. In the derivation cohort, eight functional, histological, and immunological prognostic factors were independently associated with allograft failure and were then combined into a risk prediction score (iBox). This score showed accurate calibration and discrimination (C index 0.81, 95% confidence interval 0.79 to 0.83). The performance of the iBox was also confirmed in the validation cohorts from Europe (C index 0.81, 0.78 to 0.84) and the US (0.80, 0.76 to 0.84). The iBox system showed accuracy when assessed at different times of evaluation post-transplant, was validated in different clinical scenarios including type of immunosuppressive regimen used and response to rejection therapy, and outperformed previous risk prediction scores as well as a risk score based solely on functional parameters including estimated glomerular filtration rate and proteinuria. Finally, the accuracy of the iBox risk score in predicting long term allograft loss was confirmed in the three randomised controlled trials.ConclusionAn integrative, accurate, and readily implementable risk prediction score for kidney allograft failure has been developed, which shows generalisability across centres worldwide and common clinical scenarios. The iBox risk prediction score may help to guide monitoring of patients and further improve the design and development of a valid and early surrogate endpoint for clinical trials.Trial registrationClinicaltrials.gov NCT03474003.
