Surgery chair who blamed image issues on software logs three more retractions

A researcher who claimed image problems in a retracted paper were the result of a software glitch, and not intentional, has lost three more papers — all for image manipulation.

In two notices, the Journal of Biological Chemistry specifies that duplicated images were used to represent different experimental conditions; one notice simply says the paper was affected by image manipulation.

All of the notices specify the papers are being retracted by the publisher, the American Society for Biochemistry and Molecular Biology — which this month published a set of recommendations for preparing a paper, including how to avoid excessive manipulation.

The papers were published between 2002 and 2010, and all share the same last author (Paul Kuo, currently chair of surgery at Loyola Medicine) and first author (Hongtao Guo, at Duke).

Here’s the first notice:

Prominent Harvard researcher issues second retraction, again citing duplication

The former president of the Joslin Diabetes Center has withdrawn a second article within a month of his first, and issued extensive corrections to another paper in the same journal, all due to figure errors.

In November, we reported that Carl Ronald Kahn — also affiliated with Harvard Medical School — had pulled a highly cited 2005 paper from The Journal of Clinical Investigation because of image duplication issues, which Kahn told us were introduced during figure assembly. This December, Kahn retracted a 2003 paper published in The Journal of Biological Chemistry (JBC)—again due to duplication issues that the authors believe “were inadvertently introduced during figure assembly.”

Here’s the retraction notice for “Bi-directional regulation of brown fat adipogenesis by the insulin receptor,” cited 46 times, according to Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters:

Undisclosed conflicts of interest usually lead to corrections – but for some journals, that’s not enough

When authors are faced with filling out a journal’s conflict of interest form, deciding what qualifies as a relevant conflict can be tricky. When such omissions come to light, only rarely do they result in retractions – and certainly not author bans. But there are exceptions.

In October, the journal Chest retracted a 2015 review article exploring how mechanical ventilation can be used most effectively to manage acute respiratory distress syndrome (ARDS) after finding that the authors failed “to disclose all relevant conflicts of interest.” What’s more, the journal initially planned to ban the two authors with undisclosed conflicts from submitting papers to the journal for three years, but ultimately decided against it.

The Committee on Publication Ethics says that retractions may be warranted in cases of undisclosed conflicts of interest, but in our experience, most notices that cite that reason mention other problems with the paper, as well. Not this case – here, the only thing that seemed wrong with the paper was the authors’ failure to mention their ties to a ventilator company. The authors requested a correction – the usual fix, one accepted by the other journals they contacted – but to Chest, that wasn’t enough.

Here’s the retraction notice for “Mechanical Ventilation as a Therapeutic Tool to Reduce ARDS Incidence”: Continue reading Undisclosed conflicts of interest usually lead to corrections – but for some journals, that’s not enough

Authors retract two statin papers, one with problems “too extensive to revise”

Researchers in China have retracted two 2016 papers about the possible use of a cholesterol-lowering agent to treat bleeding on the brain.

One of the retracted papers in the Journal of Neurosurgery (JNS) had multiple problems that were “too extensive to revise,” according to the lengthy retraction notice, relating to issues with authorship, data analyses, and patient enrollment. The notice is signed by first author Hua Liu of the Nanjing Medical University in China.

Liu is also the first author of another recently retracted paper in Frontiers in Neuroscience, pulled for incorrectly categorizing patients.

The JNS retraction notice begins: Continue reading Authors retract two statin papers, one with problems “too extensive to revise”

Journal retracts surgery study with data “not intended for use in research”

A journal has retracted a surgery study by researchers at Brown University after noticing it included data that was not intended for research purposes. (Incidentally, the data were collected by the publisher of the journal.)

Ingrid Philbert, managing editor of the Journal of Graduate Medical Education — which published the paper — told Retraction Watch that senior staff at the publisher alerted the journal that they suspected the authors had used data from a confidential source:

This is a fairly new set of case log data, and as the collector [of] the data, the [Accreditation Council for Graduate Medical Education (ACGME)] gets to determine the use and it has decreed that this data be used solely for accreditation decisions.

Philbert said the journal asked the authors where they got the data:

“An example for all authors to uphold:” Researcher logs 5 corrections

A scientist in Ireland has corrected five of his papers in a single journal dating back more than a decade, after image-related problems were brought to his attention.

Four of the newly corrected papers have a common last and corresponding author: Luke O’Neill of Trinity College Dublin in the Republic of Ireland. O’Neill is also a co-author of the remaining paper that was fixed. O’Neill told us the mistakes were a “bit sloppy,” noting that he takes responsibility for the errors in the four papers on which he is last author.

O’Neill forwarded Retraction Watch a comment he received from Kaoru Sakabe — data integrity manager at the American Society for Biochemistry and Molecular Biology (which publishes The Journal of Biological Chemistry (JBC)) — that reads:

Journal retracts all papers by education researcher, bringing his total to 21

jaasepA journal has followed through on its promise to retract all articles by an education researcher, after an investigation raised questions about the validity of the data in some of his work with children with special needs.

The latest notice — which includes a list of 11 papers — brings the total number of retractions for Noel Kok Hwee Chia to 21.

Last spring, The Journal of the American Academy of Special Education Professionals (JAASEP) pulled nine articles by Chia that were the subject of an investigation at the National Institute of Education in Singapore, part of Nanyang Technological University, where he worked until April. As we reported in June, editors explained in a 3,000-word notice that they planned to pull every article that Chia had published in JAASEP.

The new retraction notice quotes from the reasoning presented in the previous one, from last spring:

Prominent researcher in Taiwan loses another paper for image duplication

In November, a vice president at an institution in Taiwan retracted a hotly debated cancer paper from Nature Cell Biology, citing image problems including duplications. Now, the Journal of Biological Chemistry has done the same, again citing image duplications.

There are a few things to note about the latest retraction: One, the last author is again Kuo Min-liang — who holds an appointment at National Taiwan University (NTU), and is also a vice president at Kaohsiung Medical University in Taiwan. Kuo is currently facing allegations that he accepted bribes to add co-authors to his papers; NTU told us it is investigating the latest retraction in the Journal of Biological Chemistry, including Kuo.

The other notable feature of the retraction is the notice itself, which lists a remarkable number of duplicated images. Take a look:

Researcher loses 4th paper flagged by misconduct probe

A researcher in Germany has logged her fourth retraction following an investigation by her former employer that found evidence of scientific misconduct.

The latest retraction for Tina Wenz in the Journal of Applied Physiology mentions the probe at the University of Cologne in Germany, which recommended retracting six of her papers. One had already been retracted by the time the report was released; last month, we reported that two others had been pulled. Now, we’ve come across a fourth.

Here’s the latest retraction notice: Continue reading Researcher loses 4th paper flagged by misconduct probe

Authors in Spain issue string of corrections

Following a journal probe and questions on PubPeer about their work, authors in Spain have issued four corrections, citing missing raw data for experiments conducted more than 10 years ago.

All papers include the same last two authors, Mireia Duñach at the Autonomous University of Barcelona, and Antonio García de Herreros at the Institut Hospital del Mar d’Investigacions Mèdiques.

Three of the corrections were issued by the Journal of Biological Chemistry, from which the authors retracted three papers earlier this year after a journal investigation concluded they contain reused images, designed to represent different experiments.

Duñach told us the latest corrections are the result of her own initiation:
