22 papers by Joachim Boldt retracted, and 67 likely on the way

Self-plagiarism alert: A very similar version of this post is being published online in Anesthesiology News, where one of us (AM) is managing editor.

Anesthesia & Analgesia has retracted 22 papers by Joachim Boldt, the discredited German anesthesiologist whose prolific career as a researcher has unraveled with stunning rapidity — and 67 more retractions are likely on the way from 10 other titles  that have published his work.

The 22 retractions, announced Feb. 25 on the journal’s website, come less than a month after the state medical board overseeing an investigation into Boldt’s publications said that it was looking into more than 90 of his articles out of concern that he had failed to obtain proper approval from an institutional review board for the work.

The board, Landesärztekammer Rheinland-Pfalz (LÄK-RLP), investigated 102 articles. Investigators could not find evidence of adequate IRB approval for 89 papers; for the remaining, 11 had IRB approval and two did not require it, according to the A&A notice, which was signed by  editor-in-chief Steven L. Shafer: Continue reading 22 papers by Joachim Boldt retracted, and 67 likely on the way

University of Sao Paulo fires professor after a retraction for plagiarism

February has turned out to be a bad month for people found guilty of plagiarism. On Friday, we covered the case of the German foreign defense minister who lost his PhD after his university became aware he had copied passages from newspaper stories into his thesis.

And now we’ve learned that the University of Sao Paolo Paulo (USP) dismissed a full professor earlier this month after an investigation into a study he retracted last year because parts of it had been plagiarized. It has also stripped one of the professor’s former students of her PhD. Continue reading University of Sao Paulo fires professor after a retraction for plagiarism

Ninth Bulfone-Paus retraction notice appears, in Molecular and Cellular Biology

Another retraction notice for a paper published by Silvia Bulfone-Paus and colleagues has appeared, this one for a 2005 paper in Molecular and Cellular Biology.

The retraction notice is brief but to the point: Continue reading Ninth Bulfone-Paus retraction notice appears, in Molecular and Cellular Biology

Korean ENT journal retracts 17 papers, citing ‘overlap’

The Korean Journal of Otolaryngology-Head and Neck Surgery has retracted 17 papers, with the common theme of ‘overlap’ — almost always a euphemism for plagiarism, whether self or otherwise.

Published between 1993 and 2006, the articles came from a group of authors at the department of otolaryngology at Ajou University School of Medicine in Suwon, South Korea. Their topics range from “The Effects of Intratympanic Steroid Injection for the Patients with Refractory Sudden Sensorineural Hearing Loss” to “Study for Reversibility of Experimental Cholesteatoma Using Mongolian Gerbil.”

The retraction notices all read basically the same way. Here’s the one for the gerbil paper: Continue reading Korean ENT journal retracts 17 papers, citing ‘overlap’

TKO for knee replacement paper, but notice raises more questions than it answers

The journal Orthopedics is retracting a paper by Chinese researchers who appear to have been a little to hasty to submit their manuscript.

Titled “Comparison of the mini-midvastus with the mini-medial parapatellar approach in primary TKA,” the October 2010 paper purported to describe a prospective, randomized study comparing two approaches to total knee arthroplasty, or knee replacement surgery. The authors, from First Affiliated Hospital of Suzhou University, stated that “all knees were implanted with the same posterior-stabilized prosthesis by the same surgeon,” a Dr. Tang.

Having claimed to have separated the effects of the surgery from those of the prosthetic — in this case, the Genesis II device from Smith & Nephew — the authors said that the study was able to demonstrate that “the early clinical results are similar between the mini-midvastus and mini-medial parapatellar approach. The mini-medial parapatellar approach is easier to initially apply and provides better visualization for TKA.”

Except that it didn’t.  Continue reading TKO for knee replacement paper, but notice raises more questions than it answers

Two more Bulfone-Paus retraction notices appear

The number of retraction notices of papers co-authored by Silvia Bulfone-Paus is up to eight.

The Journal of Leukocyte Biology, which was apparently the first to announce they had accepted a retraction, has published its notice: Continue reading Two more Bulfone-Paus retraction notices appear

More on SPIROCOR noninvasive heart disease test: Second retraction (in fact the first) says little

Since we first wrote about the travails of Spirocor’s bedside, noninvasive test for coronary artery disease, we’ve been trying, without much success, to find out more information.

But as they say about every dog, our day has come.

As we initially reported, Ron Waksman, a prominent Washington, D.C. cardiologist and editor-in-chief of Cardiovascular and Revascularization Medicine, was first author of one of two papers about the Spirocor technology that were published in 2010. The other, by Shiyovich, et al, was retracted earlier this month by the American Journal of the Medical Sciences, which triggered our interest in this case.

At the time, we couldn’t find any evidence that Waksman’s article had been retracted, and Waksman has not responded to multiple requests for comment. Today we spoke with Kate Coons, the journal’s managing editor, who told us that the authors had sought a retraction for the article, “An innovative noninvasive respiratory stress test indicates significant coronary artery disease,” in December, and that it had posted one on its website on Jan. 6 of this year. It will be in print in an upcoming issue.

The notice is not available on Medline, but it can be found on ScienceDirect: Continue reading More on SPIROCOR noninvasive heart disease test: Second retraction (in fact the first) says little

Bulfone-Paus retraction notice appears in the Journal of Biological Chemistry

Silvia Bulfone-Paus

Another retraction notice for a paper by Silvia Bulfone-Paus and colleagues has appeared, this one for a 2007 paper in the Journal of Biological Chemistry (JBC), “Soluble IL-15Rα is generated by alternative splicing or proteolytic cleavage and forms functional complexes with Il-15.”

This is the sixth retraction notice of a promised 12 in several journals. The original paper has been cited 37 times,  according to Thomson Scientific’s Web of Knowledge.

Some of the notices have gone into great detail about what was wrong with the original papers, and journals have even allowed the team to declare that some of the results had been replicated. One simply said there had been misconduct.

Then there’s this one: Continue reading Bulfone-Paus retraction notice appears in the Journal of Biological Chemistry

Scandinavian Journal of Immunology publishes Bulfone-Paus retraction notice

Silvia Bulfone-Paus

Last week, we reported that the Scandinavian Journal of Immunology had noted that a 2002 paper by Silvia Bulfone-Paus and colleagues had been retracted, but hadn’t yet published the retraction notice. A commenter tipped us off this week that the notice is out: Continue reading Scandinavian Journal of Immunology publishes Bulfone-Paus retraction notice

Tangled leads: Cardiac study retraction reveals a company’s stopped trials, and lots of questions

A retraction in an obscure journal. An equally obscure retraction notice. An Israeli company with no web presence. Conflicts of interest involving authors and editors.

That’s what we’ve uncovered so far after noticing the other day that the American Journal of the Medical Sciences (AJMS) had retracted a May 2010 article by a group of Israeli heart doctors led by Arthur Shiyovich, of Barzilai Medical Center in Ashkelon.

The paper described promising results in a study of a new test for diagnosing coronary artery disease at the bedside by measuring aspects of a patient’s pulse at the fingertip.

As AJMS editor David Ploth told us, the approach had seemed “kind of innovative” to him, so he’d accepted the manuscript: “It seemed like it might have some applicability.”

Ploth was therefore surprised sometime later to receive a letter from the authors requesting that the journal retract their paper. According to the journal: Continue reading Tangled leads: Cardiac study retraction reveals a company’s stopped trials, and lots of questions
