Mega-correction to several images in gastric cancer study

20.cover

A journal has issued a rather large correction — what we call “mega-correction” — to a 2014 paper on a gastric cancer biomarker that fixes problems with several of the study’s figures.

The authors write that despite the corrections, “the results and conclusions put forth in the article remain unchanged.”

The paper, “TMEFF2 Deregulation Contributes to Gastric Carcinogenesis and Indicates Poor Survival Outcome” explored the role of TMEFF2 in gastric cancer. The researchers found that the protein acts as a tumor suppressor, and low levels can indicate the presence of cancerous cells.

Here’s the full correction notice, published by Clinical Cancer Research in August:

Authors object to duplication verdict by environmental journal

10661An environmental journal has pulled a 2011 paper following an investigation, which revealed it contained “extensive similarities” with another paper published two years earlier by some of the same authors.

Two of the authors of the newly retracted paper — Zulfiqar Ahmad from Quaid-i-Azam University and Arshad Ashraf of the National Agricultural Research Center, both in Islamabad, Pakistan — were the sole authors of a 2008 paper about modeling groundwater flow in Indus Basin, Pakistan. The 2011 paper  — posted online in 2010 — focused on the same topic, but included two additional authors, one of whom told us he was unaware of the previous paper and agrees with the journal’s decision. Ahmad, however, has defended the 2011 paper and asked that the journal remove the retraction note.

Here’s the note, published in April by Environmental Monitoring and Assessment: Continue reading Authors object to duplication verdict by environmental journal

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 revokes PhD of first author on retracted STAP stem cell papers

800px-Waseda_University_Logo.svgWaseda University has revoked the doctorate degree of the first author on the now-retracted Nature papers about a technique to create stem cells.

The technique — which claimed to provide a new way to nudge young cells from mice into pluripotency — was initially described in two 2014 Nature papers, both first-authored by Haruko Obokata. However, the papers were soon mired in controversy, corrected, then retracted later that year due to “several critical errors,” some of which were categorized by a RIKEN investigation as misconduct.

Shortly after Nature retracted the two papers, Waseda revoked Obokata’s doctorate degree — on a probationary basis, according to the university: Continue reading University revokes PhD of first author on retracted STAP stem cell papers

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:

Journal reviewing papers by researcher who sexually assaulted disabled author

Screen Shot 2015-11-03 at 12.10.00 PMA disability journal is “paying significant attention” to papers authored by Anna Stubblefield, a former Rutgers researcher recently convicted of sexually assaulting a disabled man who participated in her research.

Stubblefield was convicted of sexually assaulting “DJ,” a man in his thirties with cerebral palsy who was “declared by the state to have the mental capacity of a toddler,” according to a lengthy piece in the New York Times. Stubblefield and DJ published papers in Disability Studies Quarterly; in one, Stubblefield describes a controversial technique which she claimed helped DJ communicate. But when she eventually used the technique to say DJ was in love with her, his family took her to court, and she was convicted of aggravated sexual assault.

Here is the note from Disability Studies Quarterly, which was published this morning:  Continue reading Journal reviewing papers by researcher who sexually assaulted disabled author

Cholesterol paper duplicated; “The authors believed that they had taken the necessary steps to withdraw.”

Biological Reviews

A review journal is pulling a 2013 article about advances in researchers’ understanding of cholesterol after seeing the same article in another journal.

Although the retracted paper appeared first — online in Biological Reviews in February, 2013 — the journal decided to retract it after learning the authors had initially submitted it elsewhere. The first submission was eventually published (with the exception of one author) in 2014 in Frontiers in Bioscience. 

The authors say they “believed that they had taken the necessary steps to withdraw their paper from Frontiers in Bioscience before they submitted to Biological Reviews in June 2012.” Here’s more from the retraction notice:

Sex addiction article retracted, republished

Screen Shot 2015-10-14 at 2.01.12 PMAn open-access journal with a speedy peer review process has been having some issues with a retracted article on the biology of sex addiction.

Here’s the simple timeline of events: “Hypersexuality Addiction and Withdrawal: Phenomenology, Neurogenetics and Epigenetics,” a review article, was published by Cureus in July, following a two-day peer review. In the weeks that followed, the paper received a number of criticisms. So the journal quietly corrected it, then issued a formal correction, then retracted the paper — and now, finally, has republished it. The editor of the journal, Stanford professor emeritus John Adler, admitted the “decision was dumb” to initially fix the article without an alert, but it was ultimately doomed by “political” issues — namely, a larger debate over whether or not “sex addiction” exists at all.

We’ll start with the retraction. According to the note, it stems from the mistaken characterization of how sex addition — “hypersexuality” — is described in the current “bible” of psychiatry:

Plagiarism was “not an intentional act,” says first author of retracted TB paper

logoA 2013 review article about tuberculosis is being retracted for “unacknowledged re-use of significant portions of text” from another article, which the first author said wasn’t intentional.

Sayantan Ray, based at Medical College and Hospital, Kolkata in India, told us that “most of the unchanged text” is present in sections written by junior co-authors. Since there doesn’t appear to be any attempt to cover it up, he argued anyone responsible for the plagiarism must not have realized it was wrong:

You can appreciate that this type of obvious similarity can only happen when the concerned person [does] not have any idea about [the] plagiarism issue.

According to the notice, published by Therapeutics and Clinical Risk Management, most of the re-used text appears to have come from a 2012 paper in the Indian Journal of Medical Research. Here’s more from the notice:

Authors retract highly cited Nature quantum dot letter after discovering error

cover_nature

Authors have retracted a highly cited Nature letter that purported to discover a much sought-after, stable light source from quantum dots, after they realized the light was actually coming from another source: the glass the dots were affixed to.

When the paper “Non-blinking semiconductor nanocrystals” was published in 2009, it received some media coverage, such as in Chemistry World. That’s partly because very small sources of “non-blinking” light could have wide-ranging, big-picture applications, author Todd Krauss, a physical chemist at the University of Rochester, told us:

Off the top of my head, a quantum computer. Quantum cryptography is another one. People want a stable light source that obeys quantum physics, instead of classic physics.

The retraction note, published Wednesday, explains how the researchers found out the effect was coming from the glass, not quantum dots:
