Title: Patient Education After CABG: Are We Teaching the Wrong Information?

What Caught Our Attention: We’ve written about the controversy surrounding a commonly used tool to measure whether patients are sticking to their drug regimen, known as the Morisky Medication Adherence Scale (MMAS-8). It can cost thousands of dollars — and using it without payment/permission earns researchers a call from a collector, who has used legal threats to compel multiple teams to withdraw their papers (a phenomenon we wrote about in Science). The creator of the tool argues it’s copyrighted, and demanding fees ensures researchers use it properly, which avoids putting patients at risk. We’ve found a notice (paywalled, tsk-tsk) that reveals another group of authors used the tool without permission and, according to the notice, “incorrectly.”

Vector wasn’t a gift after all, correction notes

without comments

CirculationA paper accidentally credited the wrong researcher with providing part of an experiment.

It turns out that one of the authors supplied an expression vector to a Circulation paper about the molecular underpinnings of atherosclerosis — not the outside researcher originally thanked in the acknowledgements section.

The correction notice to the paper makes the situation sound more mysterious than it appears to be:

Biologist’s research under investigation in Sweden after being questioned on PubPeer

with 9 comments


Suchitra Sumitran-Holgersson

The University of Gothenburg in Sweden is investigating several papers co-authored by biologist Suchitra Sumitran-Holgersson after they were challenged on PubPeer.

Sumitran-Holgersson already has one retraction under her belt — of a 2005 Blood paper, after another investigation concluded the results “cannot be considered reliable.” Sumitran-Holgersson and her husband, co-author Jan Holgersson, did not sign the retraction notice. Both were based at the Karolinska Institutet (KI) at the time, but have since moved to the University of Gothenburg.

Now, the University of Gothenburg has launched its own investigation of the papers questioned on PubPeer, according to Read the rest of this entry »

Stem cell researcher that sued Harvard failed to disclose conflicts on 6 publications

with 2 comments

Piero Anversa, a stem cell researcher who we recently learned is leaving Harvard and Brigham & Women’s Hospital after suing them, has added a disclosure statement to six publications.

The four papers and two letters were published in Circulation, and all bear identical corrections:

Piero Anversa, MD, discloses that he is a member of Analogous, LLC.

The author regrets this omission.

Trouble is, we can’t find a company by that name. What we do know:

Mega-correction for updated CPR reporting guidelines

with one comment

CirculationA major correction has been posted for an update to international guidelines on reporting outcomes of people receiving cardiopulmonary resuscitation (CPR).

Circulation published the paper online in 2014; the correction was issued before it appeared in print, in the journal’s September 29, 2015 issue. “When reviewing the final proof for print publication, the author noticed some errors and requested changes,” according to a spokesperson for the journal’s publisher, the American Heart Association.

The notice is so long, we’re only including the first paragraph, most of which is taken up by just the title of the paper:

Updated: Former Vanderbilt scientist faked nearly 70 images, will retract 6 papers: ORI

with 23 comments

ori logoA former Vanderbilt University biomedical engineer committed fraud on a massive scale, according to a new Office of Research Integrity (ORI) report.

Igor Dzhura is banned from receiving federal funding for three years, and is retracting six papers, which have been cited more than 500 times. Since leaving Vanderbilt, he has worked at SUNY Upstate Medical University, and now works at Novartis.

According to the ORI, Dzhura was a busy boy at Vanderbilt, faking images and drastically inflating the number of experiments he conducted by duplicating computer files and saving them in nested folders. The total body count from his work includes: Read the rest of this entry »
