Bioethicist Arthur Caplan calls for retraction of all Macchiarini papers

Bioethicist Arthur Caplan calls for retraction of all Macchiarini papers

Arthur Caplan, internationally respected professor of bioethics and director of the Division of Medical Ethics at the New York University, requested publicly retractions of the bioethics reviews on regenerative medicine he co-authored with the scandal surgeon Paolo Macchiarini. Caplan notified the journals with his retraction requests, but said to have received no response from them yet. Not only this: Caplan calls for all works of Macchiarini to be retracted.

Macchiarini is now an international pariah, he recently again lost his job, this time with the Kazan Federal University in Russia (see my report). His publications are under investigation at his former workplace the Karolinska Institutet in Stockholm (where he was previously sacked), the Swedish state announced to soon charge him with manslaughter, due to 3 lethal plastic trachea transplants he performed at Karolinska.

Macchiarini leaves Russia: federal grant denied and Kazan lab shut down

Macchiarini leaves Russia: federal grant denied and Kazan lab shut down

Paolo Macchiarini is leaving Russia, his research and surgery stint there is over. The fallen star surgeon was able to find a professorship with the Federal University of Kazan (KFU), after his plastic trachea transplants at the Kuban State Medical University in Krasnodar left 3 patients dead, and one with a lucky escape (see details here).  His new research focus was on artificial oesophagus, which he apparently already started to test on hapless baboons. In March 2017, the Russian state decided that Macchiarini’s federal grant on oesophagus research will not be renewed, the Kazan University announced in regard to their professor’s further employment to follow the instructions from the Russian Science Foundation. The professorship contract expires by December 2017. On April 20th, Kazan University made the official decision to shut down Macchiarini’s research programme. A Russian opposition party, Yabloko, demanded of the Ministry for Research and Education to investigate Macchiarini’s Megagrant funding and the use of that money, especially in view of the fact that no final report was published. All this information was revealed by the Russian health and medicine journalist Alla Astakhova on her website.

Ciaran’s success story

Ciaran’s success story

Trachea is a very difficult organ to transplant, because its blood supply happens through many tiny blood vessels and it is practically impossible to connect them all (same is true also for the oesophagus). An organ transplanted without blood supply will die, and this is where the regenerative medicine of Paolo Macchiarini and Martin Birchall comes in: a treatment with stem cells and growth factors will somehow magically ensure quick vascularization and bring the dead tissue to life. There is no independent evidence for this, and most patients died as the consequence or became dangerously ill when their new tracheas, made from plastic or from dead, decellurised cadaveric organs predictably failed.  One boy has survived: Ciaran Lynch. His current clinical state is not too rosy, even by Birchall’s own admittance, but nevertheless the sole fact that Ciaran (unlike almost all other trachea transplant patients) is alive, sufficed for Birchall to have one or two more patients operated (both dead) and to push through a clinical trial in UK with a much larger follow-up trial EU-wide. The difference though: that boy never had much choice anyway, since he had no real trachea in the first place. He received very early on a pickled trachea homograft from dead human donor tissue which functioned very well for many years, but at some point urgently needed replacement in order to save his life. Now Birchall however wishes to remove the live airways of stable patients outside any life danger, who suffer from tracheal stenosis, and replace them with his regenerated dead ones (see this report). Noone seems to wonder why these tracheas are to be prepared in a radically different way from that of the sole success, Ciaran Lynch: Birchall’s bioreactor vs so-called “bionic” method of Macchiarini.

Retraction, and another looming misconduct finding for Macchiarini and Jungebluth

Retraction, and another looming misconduct finding for Macchiarini and Jungebluth

The misconduct-tainted paper on oesophagus transplants in rats (Sjöqvist et al 2014) by the fallen star of regenerative medicine Paolo Macchiarini is finally retracted by the journal Nature Communications. This happens after Swedish investigations found the authors (primarily the scandal thorax surgeon and his right-hand man Philipp Jungebluth) guilty of data manipulation and research misconduct in September 2016 and after the Karolinska Institutet (KI) shortly before Christmas publicly demanded a retraction (see my report here). Today’s retraction is a major setback for Macchiarini, since his current employment and funding at the Federal University of Kazan (KFU) in Russia depend on his experiments with oesophageal transplants in primates (see my reports here and here). That Russian project was in turn only possible because of Macchiarini’s allegedly successful experiments in rats, published in a prestige journal with “Nature” in its title. This paper’s retraction is therefore probably only the beginning of a whole looming avalanche of bad news for Macchiarini and his acolyte Jungebluth (who currently sues me in court). An expert review of their publication Jungebluth et al 2015 declares the findings of misconduct, ethics breach and patient abuse. The report however has yet to be confirmed by a commission at the Swedish Central Ethics Review Board (CEPN) and then formulated as an official decree by the KI. I publish the expert reviewer report below. Continue reading “Retraction, and another looming misconduct finding for Macchiarini and Jungebluth”

The Kenneth Chien Case at Karolinska, by Johan Thyberg

The Kenneth Chien Case at Karolinska, by Johan Thyberg

This is a new guest post from Johan Thyberg, a retired professor for cell and molecular biology from Sweden, a known activist against science fraud and author of the 2009 book “Scientific Fraud or Legal Scandal?”. Thyberg played a key role in uncovering the research misconduct and horrendous patient abuse around the trachea transplant surgeon Paolo Macchiarini, which took place at Alma Mater, the Karolinska Institutet (KI) in Stockholm, and left at KI alone 3 patients dead (his last plastic trachea recipient there, Yesim Cetir, died yesterday after years of suffering).

After a previous guest post by Thyberg, which criticised KI’s handling of the Macchiarini scandal, it is an honour for me to present his new article on my site. It deals with another international star of regenerative medicine whom KI recruited soon after Macchiarini: Kenneth Chien. The people who recruited Chien were also the same who made Macchiarini’s professorship at KI possible: the then-chancellor Harriet Wallberg and the cell biology professor Urban Lendahl. Both had to resign from their positions with the KI’s Nobel Committee in the wake of Macchiarini scandal (see my report here).

This is what Chien’s 20-head strong lab is working on at KI, according to its website:

“The central scientific interest of the Chien lab is to understand heart development at the molecular and cellular level, with the ultimate goal of applying the developmental principles, logic, pathways, technology, and model systems to unravel human heart disease”.

According to Thyberg, Chien’s engagement at KI is less about his actual scientific achievements, which seem objectively rather modest relative to his elite status there, but more about personal networks and money, which include pharma industry and a certain Chinese investor. One of these Chien-related businesses is Moderna Therapeutics, a biotech start-up which STAT News brought a critical special report on.

Below I am publishing Thyberg’s own English version article, a Swedish version appeared on March 17th on NewsVoice.

My Walles trachea transplant reporting fails peer review

My Walles trachea transplant reporting fails peer review

My attempt recently to inform the readers of the journal Tissue Engineering Part A about grave omissions and factual inconsistencies in the Steinke et al 2015 publication by Heike and Thorsten Walles failed spectacularly. Not because the concerns I raised about their tracheal transplants where deemed is irrelevant, far from it. It was the messenger who was seen as disreputable. The editor chose to send my letter out for peer review, despite the fact that I was never addressing the science of the paper, but the omitted, yet verified medical complications and deaths of the patients, as well as non-existent animal tests. Two of three peer reviewers simply chose not to believe me and my evidence, one of the reasons was: my blog site where I published it is not peer reviewed. I was also decreed to be scientifically incompetent, driven by personal vendetta against poor Walles (who are presently suing me at court for reporting about these transplants) and simply as a liar, who made all these things up. At the same time, the notorious third reviewer warns the editor that the journal’s readers must never see or hear of my accusations.

The vexatious life-saving question of cadaveric tracheas

The vexatious life-saving question of cadaveric tracheas

s we learned it from the Swedish documentary „Experimenten“, the scandal trachea surgeon Paolo Macchiarini didn’t much like to operate on sick cancer patients: they died too quickly after receiving a trachea transplant. This is why Macchiarini was said to have moved on to patients outside of any life-threatening conditions, like the Russian car accident victim Yulia Tuulik. She died because of the plastic trachea which Macchiarini implanted into her. Yesim Cetir, young victim of a botched operation, was slightly luckier to survive the plastic trachea, but only because it was removed and because of constant emergency care and multiple organ transplants (she is presently in very grave state). However, it seems that even Macchiarini’s cancer patients could have led a relatively long life, had they not agreed to receive his trachea transplants. And I am not speaking about the lethal plastic ones. In fact, the “biological” grafts made of decellurised dead donor tracheas were not such a great success either, and seem to have brought suffering and have shortened lives instead of prolonging them. The British UCL and its hospital UCLH are preparing their own clinical trial with cadaveric tracheas, while busily covering up their role in the Macchiarini scandal.
