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”

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

Dentistry student loses travel grant for duplicating his own work

iadrThe International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.

The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.

The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.

The IADR’s page now lists the winners with a note at the bottom: Continue reading Dentistry student loses travel grant for duplicating his own work

PubPeer files motion to dismiss Sarkar defamation case

sarkarAttorneys representing PubPeer in its defense against a subpoena by cancer researcher Fazlul Sarkar, of Wayne State University in Michigan, have submitted a motion to the Wayne County Circuit Court to quash the matter.

Sarkar’s work has appeared on the anonymized post-publication peer review site, and he isn’t happy about it. In October, he sued the site’s commenters, demanding that PubPeer release the names of his accusers. Sarkar, who has not been found to have committed research misconduct, claims he lost a lucrative job offer at the University of Mississippi as a result of the posts.

The motion — available here — argues that even if the claims of image irregularities levied against Sarkar by anonymous PubPeer posters are untrue, they don’t meet conventional standards of defamation: Continue reading PubPeer files motion to dismiss Sarkar defamation case

Paper on controversial stem cell “stamina therapy” retracted

A Korean stem cell journal has retracted a paper on a controversial Italian treatment that involves harvesting stem cells from bone marrow and injecting them back into the patient.

“Stamina therapy” has been pitched as a treatment for everything from Parkinson’s disease to coma, based on a U.S. patent application filed in 2010. The Italian government pledged about $3.9 million in 2013 to support a clinical trial for stamina therapy. More than 100 people signed up for the trials, with a wide range of neurological ailments; half were children.

However, allegations of fraud led to a criminal investigation into the Stamina Foundation’s leader, psychologist David Vannoni, as well as 17 other members of the organization. Continue reading Paper on controversial stem cell “stamina therapy” retracted

Faking data earns stem cell researcher a ban on federal funding

Screen shot 2014-12-09 at 12.01.19 PMThe Office of Research Integrity (ORI) has sanctioned Kaushik Deb, a former post-doc at the University of Missouri-Columbia, who “engaged in misconduct in science by intentionally, knowingly, and recklessly” fabricating data in papers in both Science and Nature (which ultimately rejected his manuscript).

Deb was big news in 2007, when Science retracted his paper. Articles about the case appeared in many outlets, including The Scientist and USA Today. At the time, Missouri’s research integrity officer, Rob Hall, told the Columbia Tribune that: Continue reading Faking data earns stem cell researcher a ban on federal funding
