JAMA retracts second paper by heart researcher

A heart researcher who fabricated trial participants has notched a second JAMA retraction. The retraction comes at the request of her co-authors, after an investigation by her former employer wasn’t able to confirm that this study was valid.

In September, we learned that Anna Ahimastos, who used to work at Baker IDI Heart and Diabetes Institute in Melbourne, Australia, had “fabricated [records] for trial participants that did not exist” in a JAMA trial for a blood pressure drug, according to principal investigator Bronwyn Kingwell. That trial was retracted, along with a sub analysis.

An investigation by the institute found problems or sufficient doubt in several more publications. This second JAMA retraction is number 5 for Ahimastos, of 8 total expected.

The paper, “Effect of perindopril on large artery stiffness and aortic root diameter in patients with Marfan syndrome: a randomized controlled trial” Continue reading JAMA retracts second paper by heart researcher

Scott Reuben notches 25th retraction, for a letter to the editor

Another domino has fallen for the infamous and prolific former anesthesiologist Scott Reuben. This time it’s a retraction for a letter to the editor that cites one of his since-retracted papers.

The letter, published in 2001, argues that local anesthesia is a “safe, reliable, inexpensive, and practical alternative to the use of epidural, spinal, or general anesthesia” for outpatient knee surgery. But to support his point, he uses one of his papers that has since been retracted for data fabrication.

The note from Anesthesia & Analgesia explains:

“Significant errors in the data” stop Hurricane Isaac paper

1-s2.0-S0169809515X0010X-cov150h This version of Hurricane Isaac — based on the force of nature that hit Louisiana in 2012 — didn’t get very far. Atmospheric Research has retracted a paper on a simulation of the hurricane just a few months after it was published.

The paper included two features that commonly get a paper retracted: erroneous data, and a dispute over authorship.

The 2014 paper only has one author: O. Alizadeh-Choobari, a climatologist at the University of Tehran.

Here’s the retraction note, which provides a few more details on what went wrong:

Mystery: A bullet with no entry wound, in a paper with no spell check?

“The Patient, a 60-years old Caucasian male found unconscious in a trailer park of gypsies…”

So begins a strange — and apparently not copyedited — new case report in the World Journal of Emergency Surgery. The paper concerns a patient — perhaps we should call him Rasputin — who showed up with a bullet in his left lung but no entry wound that would explain its presence.

Naturally, the authors draw the obvious conclusions:

Stem cell researcher who sued Harvard, Brigham & Women’s is leaving his post

A stem cell researcher who sued his employers, Harvard and Brigham & Women’s Hospital, is headed to Switzerland.

Piero Anversa‘s departure follows the dismissal of his suit last summer. Anversa filed the suit with colleague Annarosa Leri, claiming that an investigation into their work damaged their reputations:

they lost a multimillion-dollar offer to purchase their company, Autologous/Progenital; and both Plaintiffs have had possible employment offers at several institutions postponed.

Anversa’s lawyer, Tracey Miner, confirmed that he was moving:

Yale doc loses 2 HuffPo blog posts after secretly promoting his novel

Screen Shot 2015-11-20 at 8.54.44 AM — David Katz

The Huffington Post has retracted two blog posts by prominent Yale nutritionist David Katz after learning he had posted incredibly favorable reviews of a new novel — and not revealed that he had written the novel himself, under a pseudonym.

There’s no doubt Katz is a prolific writer — in addition to a couple hundred scientific articles and textbook chapters, Katz regularly blogs for the Huffington Post. He’s also the author of a novel, reVision, under the pen name Samhu Iyyam. Last year, Katz wrote a pair of incredibly favorable reviews of reVision on The Huffington Post that implied he had discovered the novel as a reader. The Huffington Post has taken them down, as blogger Peter Heimlich — yes, related to the maneuver — reported earlier this week. According to Heimlich, a 5-star Amazon review of “Iyyam’s” book, written by Katz, has also been removed.

In the reviews, there’s no hint that Katz is the author. In the first column, “Do We Need to Kill Our Heroes?,” published in January, Katz notes he was “delighted to find just such reflections [on that question] in my new favorite book, reVision.” Here’s the retraction note, of sorts, that appears on Huff Po in the column’s place:

Irish university strips student of PhD following investigation

Maynooth University has revoked a former student’s PhD following an investigation into the circumstances that led to two previous retractions in the Journal of Biological Chemistry.

During the investigation, Aisha Qasim Butt admitted to some misconduct in the two papers and the research that made up her PhD, according to a university statement (which you can read in full here): Continue reading Irish university strips student of PhD following investigation

BMJ Case Reports pulled three dental papers for plagiarism

We’ve stumbled upon a trio of retractions published in August, 2013 from BMJ Case Reports for “redundant publication” to a group of researchers based in India.

Editors found that the reports, which were published between 2012 and 2013, had considerable “overlaps” with articles that had been published in other journals. Although one of the retracted authors was also an author on one of the overlapping articles, the rest of the authors have no obvious connection to the previous work.

The authors of the three retracted papers are based at the Modern Dental College and Research Centre in India.

One retracted paper, “A rare occurrence of peripheral ossifying fibroma in the first decade of life and its management,” described the case of a 10 year-old girl with a lesion growing on her gums. The notice reads:

Mol bio paper pulled by PLOS following investigation into figures

PLOS Biology has retracted a paper about the molecular details of β-catenin expression following an investigation by the first author’s institution in Italy.

The investigation, by the Istituto Nazionale per la Ricerca sul Cancro, found that there were multiple “figure anomalies.” According to the note:

An explanation of inadvertent error was given for some of the issues identified, while for two issues, a satisfactory explanation could not be provided.

First author Roberto Gherzi says none of his co-authors helped prepare the figures. The authors maintain that the conclusions are unaffected, but that assurance wasn’t enough for the journal. Here’s more from the lengthy retraction note, which provides some backstory on the “serious concerns” regarding the data:

MD Anderson researcher Aggarwal up to six corrections

A highly cited cancer researcher at MD Anderson has notched three major corrections, all associated with problems in figures. One note cites “human error” as the cause.
