Former accounting prof adds his 33rd retraction

Former accounting professor James Hunton has added a 33rd retraction to his total, solidifying his position at #10 on our leaderboard.

Hunton’s official total is 33.5, since one journal retracted only one section of a paper, making it a “partial” retraction. Most of those retractions came last year, the fallout from an investigation at Bentley University which concluded that the accounting researcher had committed misconduct. Hunton resigned from the university in 2012 after his first retraction, citing family matters.

After the Bentley University investigation, the journal Contemporary Accounting Research conducted its own review of the paper, and found “no credible evidence exists to support the validity of the data in the study,” according to the retraction note for “Decision Aid Reliance: A Longitudinal Field Study Involving Professional Buy-Side Financial Analysts.”

Here’s the entire retraction note:

There’s more news to report on the story of surgeon Paolo Macchiarini, who’s been dogged by allegations of misconduct.

After the Karolinska Institutet (KI) announced it would not extend his contract and that he needed to “phase out” his research by November, it has now announced it may dismiss him.

In addition, Hans-Gustaf Ljunggren, KI’s Dean of Research, has resigned.

Here’s the statement we received from a KI spokesperson:

Journal retracts 7 papers by MD Anderson cancer researcher long under investigation

Bharat Aggarwal

An MD Anderson Cancer Center researcher who has been under investigation by the institution for at least several years has had seven papers retracted from a single journal.

Bharat Aggarwal told us in 2012 that MD Anderson was investigating his work, but in 2013 threatened to sue us for reporting on the case. Aggarwal is no longer listed in the MD Anderson directory, and an email to him there bounced.

This week, Biochemical Pharmacology retracted seven studies of which he is the only common author, noting the “data integrity has become questionable.” The papers have been cited a total of more than 500 times, according to Thomson Scientific’s Web of Knowledge; one has been designated as “highly cited.” Here are the seven retractions: Continue reading Journal retracts 7 papers by MD Anderson cancer researcher long under investigation

Macchiarini defends ethics of 2011 Lancet paper

Embattled trachea surgeon Paolo Macchiarini, who has spent more than a year fighting misconduct allegations, is defending the ethical oversight behind one of his seminal papers published in The Lancet.

The 2011 paper “Tracheobronchial transplantation with a stem-cell-seeded bioartificial nanocomposite: a proof-of-concept study” described a first-of-its-kind procedure: A 36-year-old man with recurrent tracheal cancer received an artificial airway seeded with his own stem cells. The news launched Macchiarini into the stratosphere. And then the questions came. Continue reading Macchiarini defends ethics of 2011 Lancet paper

Court dismisses lawsuit by XMRV-chronic fatigue syndrome researcher

mikovitsA California court has dismissed virologist Judy Mikovits’s lawsuit against fourteen people and two Nevada corporations, in part because she failed to submit necessary documents on time.

Mikovits is the author on a now-retracted Science paper suggesting a link between a virus known as XMRV and chronic fatigue syndrome, which has no known cause. She alleged that she was fired from the Whittemore-Peterson Institute for blowing the whistle on her former colleague’s activities, and that the defendants then colluded to imprison and defame her.

The court dismissed her case last Wednesday. According to the court minutes,

Seralini paper released by predatory publisher is plagiarized by predatory journal

ijtra-logoA 2012 paper co-authored by Gilles Seralini, who has published controversial research showing the dangers of genetically modified foods, has been plagiarized by another researcher.

The 2016 paper, published in the International Journal of Technical Research and Applications, has not been retracted, but the text comparison is fairly obvious.

It’s a case of intra-predatory crime: the International Journal of Technical Research and Applications is on the list of predatory journals compiled by Jeffrey Beall, and the Seralini paper appeared in the Journal of Environmental Protection, which is published by Scientific Research Publishing, which Beall considers to be a predatory publisher.

Here’s the abstract from Seralini’s 2012 paper, “Glyphosate Exposure in a Farmer’s Family:” Continue reading Seralini paper released by predatory publisher is plagiarized by predatory journal

8th retraction appears for researcher who faked patient records

S00219150An 8th paper has been retracted for Anna Ahimastos, a heart researcher who faked patient records.

It’s the last in a chain of retractions that were the result of an investigation by her former workplace, Baker IDI Heart & Diabetes Institute in Australia. As with the others, she did not agree to the retraction.

The investigation found fabricated patients records in some papers; in other papers, such as the newly retracted 2010 study in Atherosclerosis, the original data source could not be verified.  The latest retraction — “A role for plasma transforming growth factor-β and matrix metalloproteinases in aortic aneurysm surveillance in Marfan syndrome?” — followed up on a previous clinical trial, examining how a blood pressure drug might help patients with a life-threatening genetic disorder.

That previous trial — which also included 17 patients with Marfan syndrome treated with either placebo or perindopril — has been retracted from JAMA; the New England Journal of Medicine has also retracted a related letter.

The latest retraction note conveys similar information to the other perindopril/Marfan syndrome retractions: Continue reading 8th retraction appears for researcher who faked patient records

Anders Hamsten announced he would be resigning as vice-chancellor from Karolinska Institutet (KI) in the early hours of Saturday, February 13.

In a press release we received at 12:16 a.m. local time in Stockholm, Hamsten issued the following statement:

Following the criticism on the so called Macchiarini affair at KI I conclude it will be hard for me to serve as Vice-Chancellor with the strength and credibility this university needs. I will therefore leave office.

Good thing we published a primer on the whole story a few hours ago. To recap: Continue reading Karolinska vice-chancellor resigns following criticism of Macchiarini investigation

Reading about embattled trachea surgeon Paolo Macchiarini? Here’s what you need to know

The media has been abuzz in the last few weeks with developments in the ongoing story about “super surgeon” Paolo Macchiarini. We’ve been covering the allegations against him for years (and invited him to publish a guest post on our site). Below, we present a timeline of recent events, to keep you abreast of what we know so far.

Macchiarini was famous long before accusations of misconduct arose, once-heralded for creating tracheas from cadavers and patients’ own stem cells. However, the glow of his success was diminished somewhat after some Karolinska Institutet (KI) surgeons filed a complaint in 2014 — alleging, for instance, Macchiarini had downplayed the risks of the procedure and not obtained proper consent. In response, KI issued an external review by Bengt Gerdin of Uppsala University.

Here’s what’s happened since: Continue reading Reading about embattled trachea surgeon Paolo Macchiarini? Here’s what you need to know
