Investigation into CT scan paper reveals plagiarism

Screen Shot 2015-12-01 at 10.02.20 AMA paper on the quality of computed tomography (CT) images of the human body didn’t stand up to a close examination. It’s been retracted after an investigation found that it plagiarized work from two publications and a poster by another researcher.

The text in the Journal of the Korean Physical Society paper was taken from work by Kenneth Weiss, a radiologist at the University of Miami, and Jane Weiss, CFO of the couple’s medical imaging company. According to emails that Jane Weiss forwarded to us, Kenneth Weiss brought the plagiarism to light after a PhD student pointed out the similarities between the JKPS paper and one of Weiss’s in the American Journal of Roentgenology. Weiss notified the AJR in January. They started an investigation into the matter, and alerted the JKPS.

The retraction note for “Measurement of image quality in CT images reconstructed with different kernels” provides more details about the investigation:

Osteoporosis paper felled by concerns with “scientific integrity”

cover (3)

A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.”

An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According to the publisher, that duplicated text sparked a closer look at the text, which raised concerns about the scientific integrity of the paper.

The retraction note, published by the Journal of Bone and Mineral Research, says that the first author was responsible for the content of the paper: Continue reading Osteoporosis paper felled by concerns with “scientific integrity”

“Insufficient permission” from funder resects liver disease paper

HepatologyA study on chronic liver inflammation was pulled from the journal Hepatology because of “insufficient permission by the authors’ funding institution to submit and publish the manuscript.” 

The paper, which was published in July, looked into how steatosis, the abnormal retention of fat in the liver, turns into steatohepatitis, also known as fatty liver disease. Researchers found that Treg cells play a central role in controlling the disease.

Unfortunately, the journal’s managing editor didn’t provide any information about the nature of the permission problems, and the notice doesn’t give any details.

Here it is, in full:

In June, the NIH revised the award for Timothy Duong at the University of Texas Health Science Center at San Antonio from $332,500 per year to $0, and included this statement: Continue reading NIH rescinds grant to Texas eye researcher

Two more retractions make four for bone researcher

JAnatBone anatomists have retracted two papers on primate jawbone structure from the Journal of Anatomy due to “errors in the validation protocol and data,” marking the fourth retraction for one of the authors.

Olga Panagiotopoulou retracted two other papers over the past year, all of which were due to a common methodological problem. As Panagiotopoulou — who completed the work in the UK, before joining the University of Queensland in Australia in 2013 —  explained to us in April,

Last month, we reported on a 2012 paper in Interface whose authors had the journal issue an expression of concern about it because of “some of the data and methods.” At the time, The Royal Veterinary College at the University of London was conducting an investigation into the research.

Today, that expression of concern was upgraded to a retraction. Here’s the notice: Continue reading Elephant femur paper subject to expression of concern retracted following investigation

The beginning of the editorial (which is paywalled): Continue reading Not-so-tiny ethics issues as Micron retracts first-ever paper, and authors apologize for five duplicates

Hip disjoint: Dysplasia paper lacks proper attribution, earns retraction

ajhbcoverA suggestion: When you title your paper “Joined at the hip?”, better make sure it’s not too close for comfort to someone else’s work.

Alas, an Idaho anthropologist failed to heed that lesson when she published “Joined at the hip? A paleoepidemiological study of developmental dysplasia of the hip and its relation to swaddling practices among indigenous peoples of North America,” in the American Journal of Human Biology last October.

The article, by Samantha Blatt, of Boise State University, found that: Continue reading Hip disjoint: Dysplasia paper lacks proper attribution, earns retraction

Last week, we reported that some of the authors of a 2010 paper in the BMJ claiming to have identified Henry IV’s head thought the study should be retracted based on new evidence. Some of the other authors have now responded to that call for retraction, which appeared on the BMJ’s site alongside the paper.

Philippe Charlier, the corresponding author of the original paper, and five of the original paper’s 15 co-authors conclude after reviewing the evidence that
