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:

Author asks to retract nearly 20-year old paper over figure questions, lack of data

journal-of-biological-chemistryThe last author of a 1999 paper has asked the journal to retract it less than one month after a user raised questions about images on PubPeer.

Yesterday, last author Jim Woodgett posted a note on the site saying the author who generated the figures in question could not find the original data, and since he agreed the images appeared “suspicious,” he had contacted the journal to retract the paper.

Here’s the note from Woodgett, based at Lunenfeld-Tanenbaum

How can we improve preclinical research? Advice from a diabetes researcher

Daniel Drucker

By all accounts, science is facing a crisis: Too many preclinical studies aren’t reproducible, leading to wasted time and effort by researchers around the world. Today in Cell Metabolism, Daniel Drucker at the Lunenfeld-Tanenbaum Research Institute of Mount Sinai Hospital in Toronto details numerous ways to make this early research more robust. His most important advice: more transparent reporting of all results (not just the positive findings), along with quantifying, reporting, tracking, and rewarding reproducibility, for both scientists and journals and universities/research institutes.

Nutrition researcher Chandra, who lost libel suit, charged with health care fraud

A nutrition researcher with multiple retractions who unsuccessfully sued the Canadian Broadcasting Corporation (CBC) for libel has been charged with defrauding a state health insurance plan.

The Toronto Star reports that a warrant has been issued for the arrest of Ranjit Kumar Chandra for billing the Ontario Health Insurance Plan for “services that were either not provided or billed inappropriately.” The charges do not appear to be related to his research: Chandra worked once a week as an allergist for the past four years, the Star reports, and the alleged fraud was at least $5,000.

Authors retract study with contaminated cell lines

MBoCAuthors of a molecular biology paper have pulled it after realizing that their cell lines were contaminated.

According to the notice in Molecular Biology of the Cell (MBoC), the contamination occurred by “unknown means” in the senior authors’ laboratory, who told us the mistake was a difficult one to catch. He added that they discovered the problem after other researchers published conflicting results.

He also noted that the contaminated cell lines were not used for experiments in any other papers.

Here’s the retraction notice, issued on August 1: Continue reading Authors retract study with contaminated cell lines

Second retraction for bone researcher with lifetime funding ban

A researcher banned from funding by a Canadian agency for misconduct has earned her second retraction, after a reanalysis uncovered problems with the paper’s conclusions.

The retraction follows an investigation by Sophie Jamal‘s former workplace, the Women’s College Hospital in Toronto, which has led to a recent retraction of a JAMA paper due to data manipulation, and a lifetime funding ban from the Canadian Institutes of Health Research (CIHR).

The latest retraction stemmed from a re-analysis of the paper by the Canadian Multicentre Osteoporosis Study Group, of which the paper was a part; all authors but Jamal have requested the retraction. In the notice, the authors say that they believe no patients were harmed as a result of the “possibly invalid conclusions” in the paper, which showed patients with kidney problems were at higher risk of bone loss. A researcher told us a third paper by Jamal is also due to be retracted soon.

Here’s the retraction notice, issued by the American Journal of Kidney Diseases (AJKD): Continue reading Second retraction for bone researcher with lifetime funding ban

Who is Ranjit Kumar Chandra? A timeline of notoriety

Last month, Ranjit Kumar Chandra was denied an extension to file an appeal of his lawsuit against the Canadian Broadcasting Corporation (CBC). It seemed to mark the end of a long fall for the self-proclaimed “father of nutritional immunology,” who has ended up with multiple high-profile retractions and on the wrong end of a costly libel lawsuit.

The case had a lot of twists and turns, however. So for your convenience, we’ve compiled a timeline of everything you need to know about the events that led up to the lawsuit — where it all began, and how it ended last July, when the Ontario Superior Court of Justice ruled in favor of the CBC, and the apparent epilogue this June.

In the 1980s, Chandra was a highly regarded nutrition researcher; in 1989, he was made a member of the Order of Canada. He authored over 200 papers during his time at Memorial University of Newfoundland. He has referred to himself as the “father of nutritional immunology,” but the link to his website no longer appears to be active.

Here’s how it all fell apart: Continue reading Who is Ranjit Kumar Chandra? A timeline of notoriety

Canada funding agency bans researcher for fraud, and in first, reveals her name

The Canadian Institutes of Health Research (CIHR) has banned a bone researcher for life following a finding of misconduct. And in a first, the agency has named her, in their report out today.

The case of Sophie Jamal may be familiar to Retraction Watch readers, as we covered it in October of last year following reporting by The Toronto Star. JAMA retracted a 2011 study by Jamal and colleagues in December, as we reported, and she resigned her positions at Women’s College Hospital (WCH) and the University of Toronto.

Internet trolling paper published email without consent; retraction sparked lawsuit threat

De Gruyter

When a paper was retracted earlier this year with an opaque notice, we set out to figure out why. We’re still not entirely clear of the reason, but we’ve uncovered one aspect of the paper that raised objections from another researcher: The paper, on internet trolling, included an email he sent without his permission.

The retraction sparked our interest, both because of the journal’s opaque reasoning — saying the paper “does not fit” with the journal — and because the author (Jonathan Bishop, CEO of an independent media company called Crocels) has taken preliminary steps to sue the publisher of the Journal of Homeland Security and Emergency Management.

Here’s some of what happened before all that took place: When mechanical engineer Filippo Salustri discovered the paper included a screenshot of an email he sent to a listserv — along with his email address — his university (Ryerson in Canada) asked the publisher to retract the paper. De Gruyter re-reviewed the paper and retracted it, issuing the vague notice.

Salustri explained that the paper contains a figure with a picture of an email message:

The self-proclaimed “father of nutritional immunology,” Ranjit Kumar Chandra, has lost two more papers following the release of a misconduct investigation report by his former employer, Memorial University of Newfoundland (MUN).

The report was released last year after Chandra lost his libel suit against the Canadian Broadcasting Company (CBC). The newly retracted papers were both published in Nutrition Research. On one, the author is listed as “Amrit Jain,” who is allegedly Chandra, as well.

Here’s the retraction notice for the article by Amrit Jain:
