Shingles-stroke connection paper earns expression of concern for “errors in data presentation”

neurologyThe journal Neurology has issued an expression of concern for a paper linking shingles and stroke, which got press attention when it was published.

The journal’s note refers to “errors of data presentation,” which author Judith Breuer more narrowly defined as mistakes during transcription of a table. It’s unclear whether the results themselves – that herpes zoster, the virus that causes shingles, is a risk factor for stroke and other vascular problems – are being called into question.

Here’s the expression of concern for “Herpes zoster as a risk factor for stroke and TIA: A retrospective cohort study in the UK”: Continue reading Shingles-stroke connection paper earns expression of concern for “errors in data presentation”

Former postdoc threatens Retraction Watch with lawsuit over vague defamation claims

Varun Kesherwani
Varun Kesherwani

In April 2012, we wrote about a case of disputed authorship and misused data involving one Varun Kesherwani, a former postdoc at the University of Nebraska.

As we reported then, Kesherwani was first author of a paper in Cytokine. The second author, Ajit Sodhi, of Banaras Hindu University, claimed to have had no knowledge of the article and had not given Kesherwani permission to use the results. Thus, the retraction.

Since then, we have received numerous messages from Kesherwani objecting to our post — he claims it has hurt his employment prospects — and demanding that we take it down. At one point he even suggested in an email that we pay him to go away: Continue reading Former postdoc threatens Retraction Watch with lawsuit over vague defamation claims

What do studies of retractions tell us?

jmbeThe Journal of Microbiology & Biology Education has published a special issue on scientific ethics, and it includes an invited piece from us.

In “What Studies of Retractions Tell Us,” we decided to do a literature review of the small but growing field of retraction studies. Five years ago, this would have been a very short paper, consisting of a handful of references, but we were able to find about 30 studies to include quite easily.

Here’s the abstract: Continue reading What do studies of retractions tell us?

“You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

And now, one from the archives.

In 1989, then MIT grad student Lance Fortnow (he’s now chair of the computer science department at Georgia Tech) wrote a mathematical proof and published it as conference proceedings. He later went to publish the proof in a journal.

But he then discovered “unexpected technical challenges” and published a retraction in 1997. Both are still available on his personal website.

Not everyone would be that transparent. We reached out to ask why he left them up for people to see. He gave us his rationale: Continue reading “You don’t retract a paper, you retract the results within:” Why one scientist still displays one of his mistakes

Retraction Watch is growing, thanks to a $400,000 grant from the MacArthur Foundation

macarthurDear Retraction Watch readers, we have some exciting news to share.

After more than four years, 2,000 posts, and incredible responses from the scientific community, we are thrilled to announce that The Center For Scientific Integrity, a not-for-profit corporation we’ve established, has been awarded a $400,000 grant from the MacArthur Foundation to expand the work of Retraction Watch.

The goal of the grant — $200,000 per year for two years — is to create a comprehensive and freely available database of retractions, something that doesn’t now exist, as we and others have noted. That, we wrote in our proposal, is

a gap that deprives scholarly publishing of a critical mechanism for self-correction.

While we’re able to cover somewhere around two-thirds of new retractions as they appear, we’ll need more resources to be comprehensive. Here’s more from our proposal: Continue reading Retraction Watch is growing, thanks to a $400,000 grant from the MacArthur Foundation

The stories behind several recent inscrutable retraction notices became a bit more clear today when the Office of Research Integrity (ORI) issued findings in cases involving former researchers at the University of Chicago and the University of California, San Francisco.

The ORI found that H. Rosie Xing, a former assistant professor at the University of Chicago, Continue reading ORI sanctions former University of Chicago and UCSF scientists for faking findings

Retraction Watch has obtained copies of a misconduct complaint filed against surgeon Paolo Macchiarini, who is currently under investigation by the Karolinksa Institute in Stockholm for allegedly downplaying dangers of an experimental surgery, along with other misconduct accusations. We’re posting them here to allow researchers and clinicians to review and perhaps comment on them.

The complaint was from four surgeons at Karolinska Hospital, and was filed in August, as The New York Times reported last month. You can read the full complaint here. An excerpt: Continue reading Revealed: Complaint lodged against Macchiarini, “super-surgeon” under investigation
