Authors retract leptin paper due to “fabricated data”

CellPress_ak2The authors of a study on the effects of the hormone leptin on the liver have retracted it from Cell Metabolism, almost four months after the Office of Research Integrity (ORI) determined it contained faked data, courtesy of its first author.

However, the authors say that the paper’s conclusions remain valid, and are supported by new experiments and additional research by outside groups.

Widely covered editorial extolling importance of diet over exercise “temporarily removed”

The British Journal of Sports Medicine has “temporarily removed” an editorial arguing that physical activity alone will not cure the obesity epidemic, following an expression of concern.

In its place stands the following message:

This paper has been temporarily removed following an expression of concern.

First author Assem Malhotra, based at the Department of Cardiology, Frimley Park Hospital and Consultant Clinical Associate to the Academy of Medical Royal Colleges, told us the paper was pulled due to a “technical issue,” and an “official explanation” would be forthcoming.

Indeed, just this morning, we received a statement from Fiona Godlee, editor of the British Medical Journal, which publishes the British Journal of Sports Medicine:

“Unreliable” data suffocates third paper for Duke pulmonary team

ajrcmbOnce again, a team of Duke University scientists has retracted a paper, this time due to “unreliable” figure data.

With co-authors at the U.S. Environmental Protection Agency, the Duke team has withdrawn a paper from the American Journal of Respiratory Cell and Molecular Biology after concern about data in three figures led them to repeat one of their main experiments. They subsequently found “no evidence” supporting their previous conclusion.

By our count, it is the third retraction from a team that includes William Foster, a pulmonary researcher at the Duke Medical Center. The Duke team retracted a paper in 2013 on a related topic—the effect of early life ozone exposure on airways—from the Journal of Applied Physiology when it was discovered that, familiarly, data in a figure were “unreliable”. Recently, they also retracted a PNAS paper on asthma treatment earlier this month, due to missing primary data and mismatched data from two sources.

Malpractice case against Duke, Anil Potti settled

pottiA lawsuit filed in October 2011 against Duke University and Anil Potti, who has retracted 11 papers and corrected a number of others amidst investigation into his work, has been settled, Retraction Watch has learned.

Potti resigned from Duke in 2010 following questions about his work, and revelations that he had lied on grant applications about being awarded a Rhodes Scholarship. He now works at a cancer center in North Dakota.

The lawsuit was filed by subjects in clinical trials based on Potti’s work. Plaintiff’s attorney Thomas W. Henson, who confirmed the settlement, tells Retraction Watch: Continue reading Malpractice case against Duke, Anil Potti settled

Editor of Medical Journal of Australia fired after criticizing decision to outsource to Elsevier

Public health expert Stephen Leeder has been ousted as editor of Australia’s top medical journal after he questioned the decision to outsource the journal’s production and other tasks to publishing giant Elsevier.

Leeder, emeritus professor at the University of Sydney, told the Medical Observer he was asked to leave when he and the journal’s publisher, AMPCo, couldn’t see eye to eye on the decision:

NIH neuroscientist loses second paper, again the result of first author misconduct

Stanley Rapoport, a neuroscientist in the National Institute on Aging, isn’t having a lot of luck with his first authors. One committed misconduct and cost him a paper in the journal Age last year, and now he’s lost another paper with a different first author, but for the exact same reason.

The latest paper, in Neurochemical Research, examined whether chronic doses of aspirin reduce brain inflammation. It has been cited 14 times, according to Thomson Scientific’s Web of Knowledge.

Misconduct earns researcher a five-year ban on federal funding

ori logoA University of Minnesota former chemistry graduate student has been banned from receiving federal funding for five years based on “a preponderance of the evidence that the Respondent intentionally and knowingly engaged in research misconduct.”

Venkata J. Reddy appears to have manipulated findings in one R01 grant application. In recent years, bans are less common than having research supervised. What’s also unusual is that the sanction appeared to have begun two years ago, in 2013, because it lifts August 26, 2018. The report, which is scheduled to published tomorrow in the Federal Register, says the debarment has a “joint jurisdiction,” suggesting another agency may be involved. [See first update at end of post.]

According to the ORI notice, Reddy “intentionally and knowingly engaged in research misconduct by falsifying and/or fabricating data that was provided to his mentor” for an R01 application to the National Institute of General Medical Sciences (NIGMS). More specifically: Continue reading Misconduct earns researcher a five-year ban on federal funding

Drug study pulled after researchers admit altering trial protocol

egypt anaesthesiaThe Egyptian Journal of Anaesthesia is retracting a 2014 paper by a pair of researchers at Cairo University who appear to have tinkered with their protocol after having received ethics approval.

The paper, titled “Can Sugammadex improve the reversal profile of Atracurium under Sevoflurane anesthesia?” was written by Heba Ismail Ahmed Nagy and Hany Wafik Elkadi, both in the department of anesthesiology.

Sugammadex, or Bridion, is given to rapidly reverse the effects of drugs that keep patients motionless during surgery. It is available throughout the world but not, as it happens, in the United States, where the Food and Drug Administration has refused to approve the agent because of fears that it might provoke severe allergic-like reactions.

According to the retraction notice:

Chem paper fails to catalyze when wrong files are “inadvertently used”

joceah_v080i008.inddThree chemists at the Indian Institute of Technology Guwahati in India have retracted a paper from the Journal of Organic Chemistry because the “incorrect files were inadvertently used.”

The article, “Room-Temperature Cu(II)-Catalyzed Chemo- and Regioselective Ortho-Nitration of Arenes via C–H Functionalization,” described a protocol to perform nitration — the addition of nitro groups onto an organic compound — using an inexpensive copper catalyst.

All three authors signed the one-sentence notice:

Reporting errors sink chem paper on liquid-liquid equilibrium

Jced_coverA team of chemists at Hunan University and Zhejiang Shuyang Chemical Company in China have retracted a paper from the Journal of Chemical & Engineering Data after “inconsistencies with the literature” led them to discover “errors” in the way the data were reported.

According to the corresponding author Qinbo Wang, in December 2014, Robert Chirico, an associate editor at the journal, contacted Wang with concerns that the paper’s data were an anomaly.

Wang then went through the original notes with the first author, and realized that the data reported in the paper didn’t match the experimental results. The lab then conducted further experiments, and discovered that multiple corrections would be necessary. They were, as Wang told us: Continue reading Reporting errors sink chem paper on liquid-liquid equilibrium
