Heart researcher who faked patient data gets third retraction

Screen Shot 2015-11-06 at 6.38.09 PMA heart researcher has notched her third retraction, a small 2006 trial in Annals of Internal Medicine which seemed to show that a blood pressure drug could help people with artery disease walk further with less pain.

Earlier this year, Anna Ahimastos, formerly a researcher at Baker IDI Heart and Diabetes Institute in Melbourne, lost a larger clinical trial in JAMA and a subanalysis in Circulation Research after it was discovered she’d fabricated patient records. As principle investigator Bronwyn Kingwell told us in September:

Specifically, records were fabricated for trial participants that did not exist.

Now, following an investigation by the institute, her co-authors are proactively retracting papers, with more to come. The Annals of Internal Medicine paper, “Ramipril Markedly Improves Walking Ability in Patients With Peripheral Arterial Disease,” is being pulled due to an “inability to adequately validate primary data sources.” According to the note, Ahimastos “maintains the integrity of the data and validity of reported results:”

Child psych studies halted for “unanticipated event,” sparking misconduct investigation

We’ve just learned what sparked a University of Illinois at Chicago investigation that recently concluded a child psychiatrist had committed misconduct: An “unanticipated event during a study,” which halted three studies and resulted in a letter sent out to 350 research subjects.

Earlier this week, we reported that an investigation at the University of Illinois at Chicago found “a preponderance of evidence” that child psychiatrist Mani Pavuluri had committed misconduct. The university told the U.S. Department of Health and Human Services about the investigation in 2013. The findings of the investigation led the university to request the retractions of three papers, one of which has been pulled so far, for not properly disclosing how much medication children had received outside the study.

Today, we found out what prompted the university to launch that investigation, courtesy of a statement from a spokesperson: Continue reading Child psych studies halted for “unanticipated event,” sparking misconduct investigation

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

After court verdict, BMJ retracts 26-year-old paper

downloadToday, The BMJ retracted a 1989 paper about the role of breastfeeding and formula in infant eczema — 20 years after the data were called into question by a university report.

However, the report was kept secret — due, by some accounts, to alleged threats of a lawsuit. That is, until this year, when author Ranjit Kumar Chandra — who once dubbed himself the “father of nutritional immunology” — lost a $132 million libel case. That case, against the Canadian Broadcasting Company (CBC) for airing a three-part documentary series on allegations of fraud against Chandra, pushed the report by his former employer Memorial University of Newfoundland into the public domain.

At 26 years, the BMJ retraction is a runner up for the longest amount of time a journal has taken to retract a paper. (We know of another retraction that was 27 years in the making, and a scientist who requested the retraction of some passages of a 1955 article in 2007, after the article became fodder for creationists.)

Here’s the first part of the retraction note:

Taste researcher falsified data in two papers: ORI

ori-logoA federal report has found that a former University of Maryland postdoc “falsified and/or fabricated” data in two papers about taste receptors.

The Office of Research Integrity report found that Maria C.P. Geraedts manipulated bar graphs in the papers to “produce the desired result.” Both have been retracted. Geraedts left academia in 2014, and is now a science writer.

We reported on one retraction in July, “Gustatory stimuli representing different perceptual qualities elicit distinct patterns of neuropeptide secretion from taste buds,” published in The Journal of Neuroscience.

The other, “Transformation of postingestive glucose responses after deletion of sweet taste receptor subunits or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September. Here’s the note, which cites the university’s investigation: Continue reading Taste researcher falsified data in two papers: ORI

Author with three retractions objects to mega-correction following investigation

DevelopmentWe’ve uncovered a “mega-correction“ for a 2010 paper in Development, posted as the result of an investigation into the first author which has already led to three retractions.

Last year, the Utrecht University investigation into Pankaj Dhonukshe found “manipulation in some form” in four papers, and concluded that he committed a “violation of academic integrity.” The investigation also led to the retraction of a 2012 Cell paper and two papers in Nature that were co-authored by Dhonukshe. 

Development began investigating the corrected paper after being contacted by one of the authors and alerted to the results of the university’s investigation. The notice includes a statement from Dhonukshe objecting to the correction. Continue reading Author with three retractions objects to mega-correction following investigation

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.

Prostate cancer paper flagged by ORI is retracted following PETA prompt

cover_issue_129_en_USA federal investigation into a paper on prostate cancer has now led to a retraction. In an unusual twist, it happened following a request from the animal rights group People for the Ethical Treatment of Animals (PETA).

In January, the Office of Research Integrity reported that corresponding author Dong Xiao “intentionally fabricated data” in an Oncotarget study of how a steroid inhibits the growth of prostate cancer. Xiao, a former cancer researcher at the University of Pittsburgh, claimed that he had tumor data from more mice than he did, and falsified several figures.

In July, after no sign of the retraction, a researcher at PETA followed up with the journal, Oncotarget, on behalf of the organization “and our more than 3 million members and supporters to request the immediate retraction.”

Last month, they received a reply from the publisher, which they forwarded to us:
