When a paper is retracted, so is its previous correction–sometimes

1-s2.0-S0968089612X0018X-cov150hSometimes, the path to correcting the scientific record takes a few turns. In the case of a paper about a new cancer compound, authorship issues led to a correction and, ultimately, a retraction — along with a double-back to retract the earlier correction.

We reported on the first part of the story back in January: A 2011 paper that described a novel compound that could work as a drug for the side effects of chemotherapy was corrected in 2012 to add additional authors. But once the authors realized their supposedly novel compound had actually been synthesized by another author, they decided to retract the paper from Bioorganic and Medicinal Chemistry earlier this year, concluding “these facts made the paper inappropriate and unfaithful.”

Apparently, around the same time, the authors decided to retract the earlier correction, as well:

St. Jude investigation finds faked data in brain tumor paper

S00396060An investigation at St. Jude Children’s Hospital into “irregularities” in a figure featured in a neuroblastoma paper has concluded that the image was fabricated. The paper, published in Surgery in 2012, was retracted on Friday.

Here’s the full retraction notice for “Liposome-encapsulated curcumin suppresses neuroblastoma growth through nuclear factor-kappa B inhibition:”

More retractions, errata discovered for nursing researcher

Journal of Clinical Nursing

Since our recent coverage about a university investigation that led to multiple retractions for nursing researcher Moon-fai Chan, we’ve been alerted to a few more retractions and errata. His total is now at six retractions and four errata.

Some of our finds were published this year, and some are a few years old. Most are due to duplication; one is due to “use of a dataset without ethical approval.” Chan — now the Associate Master and Chief of Students at the University of Macau — is the first author on all but one of the papers.

We’ll start with the most recent errata. Three of Chan’s articles in the Journal of Clinical Nursing have errata notes published online in July of this year, all noting that the authors used elements of some of Chan’s other articles. Here’s the erratum note for “Exploring risk factors for depression among older men residing in Macau:”

University finds “preponderance of evidence” of misconduct by child psychiatrist

JPN39_2_CoverAn investigation at the University of Illinois at Chicago has found “a preponderance of evidence” that a psychiatrist who has received millions of dollars in federal funding has committed misconduct.

One paper co-authored by Mani Pavuluri, the director of the Pediatric Mood Disorders Program, has been officially retracted so far, from the Journal of Psychiatry & Neuroscience. UIC has requested that two others be retracted as well. None of the child participants in the three papers received medication as part of the research, but the Journal of Psychiatry & Neuroscience paper was pulled after the investigation found that Pavuluri had misrepresented how much medication some children had taken outside of the study.

On Tuesday, after we’d learned of the first retraction, Pavuluri told Retraction Watch that she didn’t “want mountains made out of molehills,” but admitted to “a bit of an [Institutional Review Board] infraction.”

The retraction note from the Journal of Psychiatry & Neuroscience lays the blame squarely on Pavuluri’s shoulders:

“Dual submission issues” retract both copies of ovarian cancer paper

Journal of Cellular PhysiologyAuthors of a study on a potential biomarker for ovarian cancer have been hit with two retractions after the results were published twice.

We don’t usually see both copies of a duplicated paper retracted, but this is a somewhat unusual case. In November 2011, a group of authors submitted the paper to Gynecologic Oncology. But two months’ prior, the first author had decided to also submit the paper to the Journal of Cellular Physiology, without listing three of the other researchers, including the primary author on the paper. It was published by the Journal of Cellular Physiology first, then by Gynecologic Oncology, both in July, 2012. 

Jie Chen, first author on both articles, “takes full responsibility for the dual submission” and “other co-authors should be exempted from all responsibilities,” as the retraction notice from Gynecologic Oncology explains.

Serial plagiarist’s retractions upped to 14

We’ve done some digging, run the numbers, and present to you a new member of our leaderbcov200hoard: orthopedic researcher Bernardino Saccomanni. Nine newly unearthed retractions of his make for a total of 14.

We first reported on Saccomanni’s work back in 2011, and identified him as a “serial plagiarist.” In the years since, he’s continued to rack up retractions for papers on the likes of ligament reconstruction and shoulder pain. On every paper, he is listed as the sole author.

Bernardino Saccomanni’s most recently listed affiliation on the papers is “Ambulatorio di Ortopedia, via della Conciliazione.” He sometimes also lists his affiliation as Gabriele D’ Annunzio University Chieti, even though, as we learned a few years ago, he hasn’t worked there for many years.

There’s a lot to cover here, so stick with us:

1) First up, “A new test for acromio-clavicolar pathology” was published in the Journal of Clinical Orthopedics and Trauma and cited zero times according to Thomson Scientific’s Web of Knowledge. Here’s the retraction note:

Diederik Stapel retraction count updated to 57

stapel_npcWe’ve learned about two more retractions we missed for Diederick Stapel, the Dutch social psychology researcher who has now racked up a total of 57 retractions by our count.

Both retractions were issued after a committee released a report which established fraud in dozens of papers co-authored by Stapel.

Stapel is still #4 on our leaderboard.

Elsevier retracting nine papers for fake peer review

elsevierThe fake peer review retraction count continues to mount.

Elsevier is retracting nine papers from five journals because fake email addresses for reviewers were provided during submission of the original manuscripts. According to a statement from the publisher: Continue reading Elsevier retracting nine papers for fake peer review

There’s “no evidence” research was conducted at all in retracted cancer paper

cov200h (1)To one reader of a paper on a nerve cancer, the researchers, based at a hospital in China, seemed to have found a very large number of cases of a rare cancer to study. That observation triggered an investigation into the paper that led to its retraction — and the concern that the authors in the paper never did the research at all.

The authors say they recruited 156 patients who had a particular kind of cancer that affects the tissue around nerves, known as malignant peripheral nerve sheath tumors. For context on how rare that is: Other researchers found a mere 1,182 new cases over a nearly four-decade period in the U.S. The study, according to the methods section of the paper, was supposedly done with patients who had a specific type of the disease, and who were

consecutively recruited from Wuhan Union Hospital, Huazhong University of Science and Technology in Wuhan (Hubei, China) between July 2000 and November 2012

According to the retraction note for “Common genetic variants in the microRNA biogenesis pathway are associated with malignant peripheral nerve sheath tumor risk in a Chinese population,” the hospital where the work was done never treated all of those patients:

Violent songs can lead to spicy food, and other lessons we learned from corrected graphic

S00221031

A correction to a 2011 paper doesn’t change its main conclusion: Hearing song lyrics about violence — “let the bodies hit the floor,” for example — can prompt aggressive behavior, even more so than violent imagery in music videos.

The correction follows an investigation by Macquarie University that found errors in data analysis to be an “honest mistake.”

During the study — “The effect of auditory versus visual violent media exposure on aggressive behaviour: The role of song lyrics, video clips and musical tone,” published in the Journal of Experimental Social Psychology — the authors measured the effect of violent songs or imagery using the “hot sauce paradigm.” In this model, researchers estimate people’s level of aggression by how much hot sauce they give another person to eat. The study found that, indeed, people who are exposed to violence — particularly, lyrics —  give more hot sauce to their neighbors. It has been cited 6 times, according to Thomson Scientific’s Web of Knowledge.

One aspect of the paper prompted a tweet from a Dutch journalist: Continue reading Violent songs can lead to spicy food, and other lessons we learned from corrected graphic
