Journal reverses acceptance of study linking vaccines to autism

A journal posted an abstract online suggesting a link between vaccines and autism. After a firestorm of criticism, it removed the abstract, saying it was going to be re-reviewed. Now, the journal has decided to formally reject it.

As we reported last month, Frontiers in Public Health removed the abstract after it sparked criticism on social media. After doing so, the journal released a public statement claiming that the paper was “provisionally accepted but not published,” noting that the journal had reverted it to peer review to ensure it was re-reviewed.

Now, Gearóid Ó Faoleán, ethics and integrity manager at Frontiers (the journal’s publisher), told Retraction Watch that after consultation with an external expert, the journal has rejected the paper, adding: Continue reading Journal reverses acceptance of study linking vaccines to autism

Diabetes researcher loses prestigious professorship

The German Research Foundation (DFG) has announced today that it is withdrawing a professorship it awarded leading diabetes researcher Kathrin Maedler in 2014.

In recent years, Maedler — based at the University of Bremen in Germany — has faced questions about her work, including allegations of duplication and image manipulation. So far, she has issued one retraction, two expressions of concern, and multiple corrections. After an investigation, the University of Bremen concluded last month that Maedler’s work contained several duplications that were the result of negligence, noting there is not enough evidence to support charges of scientific misconduct.

But this hasn’t stopped the DFG from revoking the prestigious Heisenberg professorship it awarded Maedler in 2014. A Google-translated version of statement released by the DFG (in German) today concludes that Maedler did, in fact, commit misconduct, as she

Dispute over shooter video games may kill recent paper

Can playing first-person shooter video games train players to become better marksmen?

A 2012 paper — titled “Boom, Headshot!” — presented evidence to suggest that was, in fact, true. But after enduring heavy fire from critics (one of whom has long argued video games have little lasting impact on users), the authors are planning to retract the paper, citing some irregularities with the data. Although the journal has apparently agreed to publish a revised version of the paper, last year the researchers’ institution decided to launch a misconduct investigation against one of the two co-authors.

Brad Bushman, a professor of communication and psychology at the Ohio State University, headed the research along with then-postdoc Jodi Whitaker, now an assistant professor at the University of Arizona.

According to a recent email from the editor of Communication Research to two critics of the paper, the retraction notice will look something like this:  Continue reading Dispute over shooter video games may kill recent paper

Researchers retract paper after they run out of breast milk

ejcn

If you think something is amiss with your data, running an experiment again to figure out what’s going on is a good move. But it’s not always possible.

A team of researchers in Seoul recently found themselves in a bind when they needed to check their work, but were out of a key substance: breast milk.

The shortage led them to the retract their 2016 paper on a micronutrient found in breast milk that helps protect infants’ retinas. “Association between lutein intake and lutein concentrations in human milk samples from lactating mothers in South Korea,” was published online last spring in the European Journal of Clinical Nutrition. 

Here’s the retraction notice:

A first for us: Journal retracts obituary (but not for the reasons you think)

journalofdigestivediseasesOn December 31st 2014, a pioneer in the study of inflammatory bowel disease passed away. An obituary published in the Journal of Digestive Diseases shortly thereafter is typical enough: It describes his achievements, importance to his patients, and battle with pancreatic cancer.

But “Loss in the Last Day of 2014: a Eulogy for Prof. Bing Xia” has now been retracted.

This is the first time we’ve seen an obituary pulled from a journal. Unfortunately, this was not a case of a premature obituary (which happens more often than you’d think)– the researcher did actually die, but it appears the journal published the obituary in the wrong place.

The retraction notice, published earlier this year, explains:

BMJ won’t retract controversial dietary guidelines article; issues lengthy correction

bmjThe BMJ has released a detailed correction to a much-debated article critiquing the expert report underlying the U.S. dietary guidelines.

After the article was published in 2015, the Center for Science in the Public Interest (CSPI) organized a letter signed by more than 100 researchers, urging the publication to retract the article. Today, the journal said it found “no grounds” to do so.

However, in a press release accompanying the announcement of the correction, the BMJ notes that some aspects of the CSPI’s criticisms were merited.

Editor in chief Fiona Godlee said in a statement:

Former Stanford researcher up to 5 retractions for unreliable data

journal-of-memory-and-languageA psychology researcher formerly based at Stanford University has logged her fifth retraction due to unreliable results.

According to the notice in the Journal of Memory and Language, Sandra Lozano takes full responsibility for the retraction.

Apparently, the retraction has been in the works for eight years — and in that time, journals have retracted four other papers co-authored by Lozano.

A Stanford spokesperson told us: Continue reading Former Stanford researcher up to 5 retractions for unreliable data

Study linking vaccines to autism pulled following heavy criticism

Frontiers in Public HealthA study linking vaccines to autism and other neurological problems has been removed by a Frontiers journal after receiving heavy criticism since it was accepted last week. 

The abstract — published online in Frontiers in Public Health after being accepted November 21 — reported findings from anonymous online questionnaires completed by 415 mothers of home-schooled children 6-12 years old. Nearly 40 percent of children had not been vaccinated, and those that had were three times more likely to be diagnosed with neurodevelopmental disorders such as autism, the study found.

After receiving criticism on Twitter, Frontiers released a public statement, noting that the study was only “provisionally accepted but not published,” and is being re-reviewed. When asked for a comment, a Frontiers spokesperson referred us to the statement. Continue reading Study linking vaccines to autism pulled following heavy criticism

Patient didn’t okay including her picture in plastic surgery paper

indian-journal-of-plastic-surgeryA plastic surgery journal in India has retracted an article about rehabilitation following removal of an eye after a patient contacted the editors to say she hadn’t consented to publish her picture.

Mukund Jagannathan, the journal’s editor-in-chief and a plastic surgeon in India, told Retraction Watch:

The patient wrote to the editor, mentioning that her photo was present in the article originally published, and politely asked us to remove her photos from public display on the Internet.

Asked whether the journal considered issuing a partial retraction to only hide the patient’s identity, Jagannathan said: Continue reading Patient didn’t okay including her picture in plastic surgery paper

Study errors “may have placed you or your child at a greater risk of harm”: 2014 letter to parents

Mani Pavuluri
Mani Pavuluri

Three psychiatric studies of children contained a myriad of problems that may have put participants at greater risk than was disclosed by consent forms, according to a 2014 letter sent to hundreds of the participants and their families.

Through a public records request, we’ve obtained a copy of the letter — which lists a host of problems in the studies, ranging from enrolling ineligible patients, not informing families of the risks associated with the studies, and skipping tests intended to minimize the risks associated with lithium.

In 2013, Mani Pavuluri told the University of Illinois at Chicago that one of her study participants had been hospitalized — an event which prompted the university to halt three of her studies, launch a misconduct probe, and send letters to approximately 350 families of children participating in the research, notifying them of what happened.

The letter concludes:
