Medical journal retracts study over fake review, authorship concerns

european-journal-of-medical-researchA journal has retracted a 2015 study about lung cancer after learning the peer-review process had been compromised.

The paper was published in March, 2015 — the same month publisher BioMed Central (BMC) pulled 43 papers for fake reviews.

According to the retraction notice in the European Journal of Medical Research, the authors’ institution in China informed the publisher that the authors had used a third party to help with copyediting and submission to the journal, raising concerns about the authorship of the paper.

Here’s the retraction notice, published in August: Continue reading Medical journal retracts study over fake review, authorship concerns

Hospitalization of participant in child psych study prompted misconduct inquiry: Letter

The adverse event that prompted the University of Illinois at Chicago to shutter three trials by a child psychiatrist occurred when one of the study subjects was hospitalized.

According to a 2013 letter obtained by Retraction Watch through a public records request, the subject was admitted to a 10-day inpatient treatment program after exhibiting an increase in irritability and aggression, which prompted researcher Mani Pavuluri to notify the university’s Institutional Review Board (IRB) in January of that year. As a result, the university halted three studies by Pavuluri, sent out letters to 350 research subjects, and launched a misconduct inquiry.

Here’s how the document describes the event (with some details blacked out): Continue reading Hospitalization of participant in child psych study prompted misconduct inquiry: Letter

Authors pull malaria study after arguing over the results

journal-of-advanced-pharmaceutical-technology-researchResearchers have retracted a study about malaria infections in India after follow-up research unveiled problems with the data and set off a dispute among the authors.

According to the notice, when the authors continued their research on the same topic, some of the new data raised concerns about what was reported in the 2010 paper. That set off a “number of disputes between authors,” which led them to retract the paper.

This account was supported by the study’s first and corresponding author, Naitik Trivedi, from the A.R. College of Pharmacy & G.H. Patel Institute of Pharmacy in Anand, Gujarat, India. Trivedi told us he believes the previous study didn’t include some relevant parameters, which affected the results. 

Trivedi noted that all the authors agree to the retraction, adding: Continue reading Authors pull malaria study after arguing over the results

Earlier this month, Morris Karmazyn, an award-winning cardiovascular researcher who’s published hundreds of papers, was called into a meeting with the office of faculty relations at the University of Western Ontario, and terminated.

The reason? A series of image problems in some of his papers, raised by a former member of his lab. When Karmazyn, Canada Research Chair in Experimental Cardiology, was told it was a case of “misconduct,” he was floored: Continue reading Prominent heart researcher dismissed by Ontario university; colleagues appeal

Journals flag two papers by psychologist Jens Förster

forster-j-a1Journals have flagged two papers by prominent social psychologist Jens Förster — whose work has been subject to much scrutiny — over concerns regarding the validity of the data. 

Förster already has three retractions, following an investigation by his former employer, the University of Amsterdam (UvA) in the Netherlands. In 2014, we reported on the first retraction for Förster for one of three studies with odd patterns that were flagged by the UvA investigation, a 2012 paper in Social Psychological and Personality Science; subsequently, the Netherlands Board on Research Integrity concluded that data had been manipulated. Three statistical experts from the UvA then carried out a more in-depth analysis of 24 publications by Förster, and found eight to have “strong evidence for low scientific veracity.”

Last year, Förster agreed to retract two more papers as part of a deal with the German Society for Psychology (DGPs); those retractions appeared earlier this year. All three papers that Förster has lost until now are from the “strong evidence for low scientific veracity” category. Recently, two more of Förster’s papers from the same category were flagged with notices, but not retracted.

One “statement of institutional concern,” issued by Personality and Social Psychology Bulletin, reads:

Retracted paper linking HPV vaccine to behavioral issues republished after revisions

immunological-researchA retracted study linking the vaccine for human papillomavirus (HPV) to behavioral problems in mice has been republished by a different journal.

The paper has been significantly revised, an author told us, but it still comes the same conclusions. 

In February, the journal Vaccine temporarily removed the study without explanation, and told the authors the editor had asked for further review. Later that month, Vaccine retracted the paper, citing “serious concerns regarding the scientific soundness of the article,” and “seriously flawed” methodology. 

In July, another journal — Immunologic Research — republished the paper. The new version of the paper has been significantly changed, co-author Christopher Shaw from the University of British Columbia (UBC) told Retraction Watch:

The Ohio State University (OSU) has settled a lawsuit with a CrossFit affiliate over allegations that a study had defamed the gym.

As first reported by Columbus Underground, the university has agreed to pay Mitchell Potterf, owner of Fit Club in Columbus, Ohio, $145,000 to settle claims that a 2013 paper by OSU researchers included false data about injuries suffered by 11 athletes who took part in a fitness challenge. According to a statement filed by Potterf and his attorney, Ken Donchatz, in the Ohio Court of Claims, based on depositions, Continue reading Ohio State, CrossFit gym make six-figure settlement over corrected paper’s injury claims

Despite retraction, antipsychotics still effective, safe for dementia, says author

alzheimers-research-and-therapyResearchers have retracted a systematic review that suggested that antipsychotic drugs are effective and safe for patients with symptoms of dementia — but claim their re-analysis of the updated data still comes to the same conclusions.

According to the retraction notice in Alzheimer’s Research and Therapy, some participants were incorrectly included twice in the meta-analysis. 

The corresponding authors recently lost another paper for an entirely different reason — earlier this year, we reported on a retraction in Annals of Neurology for Jin-Tai Yu and Lan Tan, affiliated with the Ocean University of China, Qingdao University, and Nanjing Medical University in China. The authors pulled that paper after appearing to pass off others’ data as their own.

Here’s the retraction notice for the review, issued earlier this year: Continue reading Despite retraction, antipsychotics still effective, safe for dementia, says author

Authors fix three Diabetes papers flagged for image issues

diabetesResearchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer.

All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong.

Since the corrections appear relatively extensive, we asked the journal if retractions were ever on the table. According to Chris Kohler, associate publisher, scholarly journals at American Diabetes Association, which publishes Diabetes, an ethical panel reviewed the papers before allowing the authors to issue the errata, all of which were published online this month: Continue reading Authors fix three Diabetes papers flagged for image issues
