Updated: Vaccine-autism study retracted — again

with 18 comments

For the second time, a journal has quickly retracted a study that suggested vaccines raise the risk of autism and other neurodevelopmental disorders.

The study first raised a furor last year, prompting a Frontiers journal to quickly retract it. After it was republished in the Journal of Translational Science this month, that journal has also retracted it.

Although the titles of the two papers changed, the abstracts were nearly identical. Both studies surveyed the parents of 666 home-schooled children, 39% of whom where not vaccinated, and concluded that vaccination increased the risk of neurodevelopmental problems, particularly if children were born prematurely.

A representative of the Journal of Translational Science told us “Pilot comparative study on the health of vaccinated and unvaccinated 6- to 12-year-old U.S. children” has been retracted, and it will update us with an explanation.

Here’s more from the (now-retracted) abstract:

Former rising star found guilty of misconduct issues 2nd retraction

with 3 comments

A once-lauded researcher in the field of infectious disease — who has since been found guilty of misconduct — has retracted a second paper.

Last year, the University of Dundee in Scotland investigated and ultimately concluded that Robert Ryan — whose work focused on infections that can be deadly in people with lung diseases such as cystic fibrosis — had committed “serious research misconduct,” affecting multiple publications. After appealing the decision, Ryan resigned.

We covered his first retraction earlier this month, which cited multiple instances of image duplication. Now Ryan has retracted his second paper, published in 2011 in Journal of Bacteriology, also due to image problems.

“Think of the unthinkable:” JAMA retraction prompts author to urge others to share data

with 4 comments

A few months ago, a researcher told Evelien Oostdijk there might be a problem with a 2014 JAMA study she had co-authored.

The study had compared two methods of preventing infection in the intensive care unit (ICU). But a separate analysis had produced different results.

Oostdijk, from the University Medical Center Utrecht in The Netherlands, immediately got to work to try to figure out what was going on. And she soon discovered the problem: The coding for the two interventions had been reversed at one of the 16 ICUs. This switch had “a major impact on the study outcome,” last author Marc Bonten, also from the University Medical Center Utrecht, wrote in a blog post about the experience yesterday, because it occurred at “one of the largest participating ICUs.”

When Oostdijk and a researcher not involved in the study analyzed the data again, they discovered a notable difference between the revised and original findings: The new analysis revealed that one of the interventions had a small but significant survival benefit over the other.

Oostdijk and Bonten, who supervised the re-analysis, notified their colleagues of the revised study outcomes and contacted the journal requesting a retraction and replacement, which was published yesterday in JAMA.

According to the notice of retraction and replacement:

Once-prominent researcher logs retraction following misconduct finding

with one comment

A researcher who resigned from the University of Dundee in Scotland after it concluded he was guilty of misconduct has issued his first retraction.

According to an internal email to staff forwarded to us last year, the university concluded that Robert Ryan had misrepresented clinical data and images in 12 different publications. The first retraction, published by Molecular Microbiology, cites image duplications in multiple figures.

Here’s the full notice:

Nature paper adds non-reproducibility to its list of woes

with one comment

Despite taking some serious hits, a 2006 letter in Nature isn’t going anywhere.

Years ago, a university committee determined that two figures in the letter had been falsified. The journal chose to correct the paper, rather than retract it — and then, the next year, published a correction of that correction due to “an error in the production process.” To round it out, in June of last year, Nature published a rebuttal from a separate research group, who had failed to replicate the letter’s results.

Still, the first author told us there are no plans to retract the paper, since the follow up experiments published in the corrections confirmed the paper’s conclusions.

Paper quickly retracted after author used another group’s work

without comments

The author of a 2016 paper has agreed to retract it after an investigation revealed that most of the article came from another research group at the same university.

According to the notice, the author based the majority of his paper on results generated by other scientists without their permission.

Here’s the retraction notice for “Controlled synthesis of magnetic block copolymers for anti-microbial purpose,” published in the Journal of Applied Polymer Science in November and retracted in February: Read the rest of this entry »

“Crucial experiments” missing from retracted plant study

without comments

A 2016 study was retracted from a Frontiers journal after editors realized the authors had omitted experiments that didn’t support the hypothesis. 

Gearóid Ó Faoleán, ethics and integrity manager at Frontiers, which publishes Frontiers in Plant Science, told us:

In accordance with our complaints protocol, the Field Chief Editor led the investigation that resulted in the decision to retract the paper.

JAMA article on zinc for the common cold retracted

with one comment

Authors have retracted a JAMA article summarizing the evidence behind the benefits of a supplement, after the systemic review upon which it was based was withdrawn.

The 2014 paper, “Oral Zinc for the Common Cold,” drew from a 2013 Cochrane Review, considered the gold standard for rigorous analyses of clinical treatments. That Cochrane review was withdrawn last year, a decision that the editors upheld this past September. Both were co-authored by Rashmi Ranjan Das, of the All India Institute of Medical Sciences, in Bhubaneswar, and Meenu Singh, of the Post-Graduate Institute of Medical Education and Research, in Chandigarh, India.

JAMA editor in chief Howard Bauchner told Retraction Watch that this week’s retraction followed an investigation by the journal: Read the rest of this entry »

Journal reverses acceptance of study linking vaccines to autism

with 10 comments

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: Read the rest of this entry »

Study linking vaccines to autism pulled following heavy criticism

with 23 comments

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. Read the rest of this entry »
