Prominent food researcher retracts paper from JAMA journal, replaces it with multiple fixes

with 2 comments

Brian Wansink

Earlier this week, we reported that high-profile food researcher Brian Wansink — who’s faced months of criticisms about his research — had issued his second retraction. On Thursday, he issued his third.

The retracted paper — a 2012 research letter in the Archives of Pediatrics and Adolescent Medicine, now JAMA Pediatrics — reported that children were more likely to choose an apple over a cookie if the apple included an Elmo sticker. The same day the paper was retracted, Wansink and his co-authors published a replacement version that includes multiple changes, including to the methodology and the results.

The retraction notice lists the mistakes, which the authors say they made “inadvertently:”

“A gut-wrenching experience:” Authors retract, replace JAMA paper

without comments

When economist Jason Hockenberry looked at data comparing some of the financial issues facing different U.S. hospitals, he was surprised by what he saw.

Hockenberry was examining the effects of a recently introduced U.S. program that penalizes hospitals with relatively high rates of readmissions for certain conditions by reducing Medicare payments. Although Hockenberry expected hospitals that serve low-income and uninsured patients to have more readmissions (and therefore more penalties), he saw these so-called “safety-net hospitals” had been steadily improving their performance since the program began in 2012, and had faced fewer penalties over time.

The results were so striking, they ended up in JAMA on April 18, 2017. But within one week after publication, Hockenberry learned outside researchers had raised questions about the analysis.

The outside researchers thought the authors had incorrectly categorized some of the safety-net hospitals. After looking into their concerns, Hockenberry — based at Emory University in Atlanta — realized the analysis did contain errors that affect the findings. This week, he and his co-authors retracted the article, replacing it with a corrected version. The new paper still reports that the gap between the penalties faced by safety-net and non-safety-net hospitals is closing — but not for the reasons they initially thought.

Journal republishes withdrawn paper on emergency care prices, amid controversy

without comments

The Annals of Emergency Medicine has republished a controversial paper it withdrew earlier this year which compared the cost of emergency care at different types of facilities.

Because the paper drew heavy criticism when it was originally released, the journal has published a revised version, along with several editorials and discussions between the authors and critics. One point of contention: The analysis stems from data provided by an insurance company — Blue Cross Blue Shield — which it declined to share.

The paper — originally published in February —  caught national attention (and raised concerns among some emergency care providers) when it reported the cost of treatment in emergency departments can be significantly higher than at urgent care centers, even for the same conditions. The journal withdrew the paper in spring, and re-published it Tuesday, with minor changes.

First author Vivian Ho at Rice University told us she made “slight changes”  to some headings, phrases, and the appendix, but:

Stem cell scientist appealing dismissal loses another paper

with 7 comments

Susana Gonzalez

A once-prominent stem cell biologist, who recently lost both her job and a sizable grant, has lost her fifth paper.

Recently, Molecular and Cellular Biology retracted a 2003 paper by Susana Gonzalez. Last February, the National Center for Cardiovascular Research (CNIC) in Spain dismissed her from her position over allegations of misconduct. The reason: suspicions of data manipulation.

As with a previous retraction, the journal said Gonzalez “could not be reached for approval of this retraction.”  

Here’s the full notice:

Project to “fact check” genetic studies leads to three more retractions. And it’s just getting started.

with one comment

Jennifer Byrne

A project to identify studies doomed by problematic reagents has triggered three more retractions, bringing the total to five.

Jennifer Byrne, a scientist at the University of Sydney, who developed the the idea of double-checking the nucleic acid sequences of research materials — thereby ensuring studies were testing the gene in question — told Retraction Watch that all three retractions came after she started emailing journals in January  to alert them to the problems: Read the rest of this entry »

Two more retractions for former US prof who altered dozens of images

without comments

Two journals have retracted papers by a biologist who was recently found guilty of misconduct by his former employer, the University of Colorado Denver, bringing the total to five.

The investigation report by UC Denver, which we obtained earlier this year via a public records request, had recommended one of the two newest retractions, which appears in the journal Hepatology. The other retraction, in the Journal of Immunology, was not flagged by the report — which found, among other conclusions, that Almut Grenz had altered multiple values in research that had already been submitted for peer review.

Here’s the notice for the Journal of Immunology paper:

Given “wrong pathology slides,” heart journal retracts paper

with 2 comments

A cardiology journal has retracted a paper after the authors were unable to provide correct pathology slides to replace the wrong ones submitted with the original manuscript.

The paper is titled “Aortic Valve Endocarditis and Coronary Angiography With Cerebral Embolic Protection,” published on April 10, 2017 in The Journal of the American College of Cardiology: Cardiovascular Interventions (JACC:CI). It has not yet been cited, according to Clarivate Analytics’ Web of Science.

JACC:CI retracted the paper on Aug. 14, providing this notice: Read the rest of this entry »

Journal knew about problems in a high-profile study before it came out — and did nothing for over a month

with 10 comments

In June, Gene Emery, a journalist for Reuters Health, was assigned to write a story about an upcoming paper in the Journal of the American College of Cardiology, set to come off embargo and be released to the public in a few days. Pretty quickly, he noticed something seemed off.

Emery saw that the data presented in the tables of the paper — about awareness of the problem of heart disease among women and their doctors — didn’t seem to match the authors’ conclusions. For instance, on a scale of 1 to 5 rating preparedness to assess female patients’ risk (with 5 being the most prepared), 64% of doctors answered 4 or 5; but the paper said “only a minority” of doctors felt well-prepared (findings echoed in an accompanying press release). On Monday June 19, four days before the paper was set to publish, Emery told the corresponding author — C. Noel Bairey Merz, Medical Director of the Women’s Heart Center at Cedars-Sinai in Los Angeles — about the discrepancy; she told him to rely on the data in the table.

But the more Emery and his editors looked, the more problems they found with the paper. They alerted the journal hours before it was set to publish, hoping that was enough to halt the process. It wasn’t.

“The paper is extremely flawed:” Journal retracts article linked to vaccines

with 9 comments

A journal has retracted a 2016 paper after receiving criticism from outside researchers who raised concerns about its methodology and data.

The paper shares multiple authors with another paper that linked the vaccine for human papillomavirus (HPV) to behavioral problems in mice. Last year, a journal removed the study; later that year, the authors published a revised version in another journal. The latest retracted paper focuses on the antibodies present in a form of lupus.

Yehuda Shoenfeld at Tel-Aviv University in Israel, the corresponding author on both this latest retraction and the HPV vaccine paper, recently edited a textbook that explored how vaccines can induce autoimmunity in some people.  He told us the 2016 lupus paper does have a link to vaccines [his emphasis]:

Journal corrects paper by researcher sanctioned for misconduct

with 2 comments

A biology journal has issued a correction to a 2014 paper by a researcher with 11 retractions, citing “inadvertent errors” that don’t affect the conclusions.

The researcher, Rony Seger, was recently sanctioned by his institution (The Weizmann Institute in Israel) following a finding of “serious misconduct” involving data manipulation. Specifically, the institute barred him from supervising graduate students, even future ones; his lab is now dedicated to replicating his previous work, with the help of a technician.

Last month, Michal Neeman, vice president of The Weizmann Institute of Science, told us she wasn’t sure how many additional papers by Seger would need to be retracted or corrected.

Recently, one more was revealed — in the August issue of Molecular and Cellular Biology, the following correction notice appears:
