Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Note to authors: If a journal asks you to suggest reviewers for your submitted manuscript, don’t thank them by faking the reviewer’s emails.

You might just get caught.

That’s what happened recently at Experimental Parasitology, according to the retraction notice for “Entamoeba histolytica: Cloning, expression and evaluation of the efficacy of a recombinant amebiasis cysteine proteinase gene (ACP1) antigen in minipig:” Continue reading Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

This one’s like taking candy from a baby.

The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print.

The paper was titled “Mineralized Tissue Formation by Bone Morphogenetic Protein-7–transfected Pulp Stem Cells“. According to the notice: Continue reading Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

Journal retracts antipsychotic study when all subjects’ PET scans turn out to be unreliable or invalid

The Journal of Psychiatric Research is retracting a 2010 paper claiming to show a relationship between quetiapine (Seroquel) and certain lab tests and brain scans, after it turns out the brain images were either unreliable or invalid.

Here’s the notice for “Relationship between dopamine D2 receptor occupancy, clinical response, and drug and monoamine metabolites levels in plasma and cerebrospinal fluid. A pilot study in patients suffering from first-episode schizophrenia treated with quetiapine”: Continue reading Journal retracts antipsychotic study when all subjects’ PET scans turn out to be unreliable or invalid

Confusion as JNCI yanks press release on embargoed breast density-cancer study after authors see error

An unusual note went out to reporters on the Journal of the National Cancer Institute (JNCI) press list yesterday:

Please disregard this MTM, which was sent out on Friday June 29, 2012.  The data in the study changed so we are no longer putting out a press release for the study.

The original release was headlined:

Percent Density May Be As Strong a Risk Factor as Variation in Breast Density for Breast Cancer

MTM stands for “memo to the media.” What wasn’t clear was whether the new notice meant the release was being pulled back, or the study itself, but the JNCI press office said it was just the release.

But the Mayo Clinic’s Celine Vachon told Retraction Watch: Continue reading Confusion as JNCI yanks press release on embargoed breast density-cancer study after authors see error

Clinical Endoscopy retracts sedation paper, creates neologism in process

Clinical Endoscopy, the official journal of the Korean Society of Gastrointestinal Endoscopy, has retracted a 2011 paper on sedation practices.

Although the retraction statement is underpowered for information, it has a charming neologism. To wit, the announcement for the paper, “Comparison of midazolam alone versus midazolam plus propofol during endoscopic submucosal dissection,” is a “noticement.”

Unfortunately, that’s about all that’s interesting about this retraction. Or rather, that’s the only thing on which we can comment, given the notice itself:

Does anesthesiology have a problem? Final version of report suggests Fujii will take retraction record, with 172

Japanese investigators have concluded that Yoshitaka Fujii, an expert in postoperative nausea and vomiting whose findings drew scrutiny in 2000 but who continued to publish prolifically for a decade after, fabricated his results in at least 172 published studies.

That number nearly doubles that of the current unofficial retraction record holder, Joachim Boldt.

An inquiry by the Japanese Society of Anesthesiologists (JSA) has determined that Fujii, who was fired in February from his post at Toho University, falsified data in 172 of 212 papers published between 1993 and 2011. Investigators said they found no evidence of fraud in three of the papers, but could not determine whether the results reported in the remaining 37 were reliable.

Of the 172 bogus studies, 126 involved randomized controlled trials. Investigators believe this was not a coincidence: Continue reading Does anesthesiology have a problem? Final version of report suggests Fujii will take retraction record, with 172

One year later, transcendental meditation study yanked minutes before publication still under review

A paper looking at the use of transcendental meditation to reduce the risk of heart disease, and that was put on hold just 12 minutes before its scheduled publication time, is still under review a year later.

On June 29 of last year, we brought you the news of the highly unusual — if not unprecedented — occurrence at the Archives of Internal Medicine. As we wrote then: Continue reading One year later, transcendental meditation study yanked minutes before publication still under review

Report: Fujii faked data in at least 172 papers

A Japanese web site is reporting that Yoshitaka Fujii, a Japanese anesthesiologist suspected of widespread data fabrication, did indeed fake his results in at least 172 published studies.

According to the article, on a site called Jiji Press: Continue reading Report: Fujii faked data in at least 172 papers

Withdraw that emotion: Psych journal retracts two Stapel papers on mood

Two more papers from Dutch fraudster Diederik Stapel have been retracted. Both appeared in the journal Psychological Science in 2008, with the same, evidently unwitting co-author, Kirsten Ruys, of Tilburg University.

Here is the notice: Continue reading Withdraw that emotion: Psych journal retracts two Stapel papers on mood

Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers

The body count has reached three for a group of German tissue engineers who appear to have cloned their data in many of their publications.

Tissue Engineering Part A has retracted one of the papers from the investigators, titled “Clinically established hemostatic scaffold (tissue fleece) as biomatrix in tissue- and organ-engineering research,” which was published in 2003.

The notice states: Continue reading Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers
