Bone researcher manipulated data in JAMA study, says investigation

A bone researcher manipulated data in a 2011 JAMA study about an inexpensive treatment for osteoporosis. That’s the conclusion of an investigation at the researcher’s former workplace, the Women’s College Hospital in Toronto, the Toronto Star reports. The study — led and manipulated by Sophie Jamal — followed 243 women over two years, as they applied nitroglycerin ointment once … Continue reading Bone researcher manipulated data in JAMA study, says investigation

Weekend reads, part 1: Pirating paywalled papers; a sex scandal and fudged data at Stanford

The week at Retraction Watch featured a lot of movement on our leaderboard, with a new total for Diederik Stapel, and a new entry. It also featured a lot going on elsewhere, so here’s part I of Weekend Reads (we’ll have more tomorrow morning):

Authors defend publishing clinical trial six times, even as they earn two more retractions

In August, we reported on a clinical trial on hundreds of hypertensive patients that was published six times. Now, copies published in Expert Opinion on Drug Safety and Journal of the American Society of Hypertension (JASH) have been retracted, making for a total of three retractions for the group of papers. The authors have defended the papers as being decidedly … Continue reading Authors defend publishing clinical trial six times, even as they earn two more retractions

Weekend reads, part 2: Criminalizing scientific fraud; Nobel Prize folly; boosting impact factor

There were so many items to choose from this week for Weekend Reads — probably because it was Peer Review Week — that we decided to split them into two posts. Here’s part 2:

Publisher bans authors for apparent plagiarism

Three authors have been banned from journals published by IGM Publication, including the Journal of Medical Science and Clinical Research. The ban — a relatively infrequent occurrence in publishing — comes after the publisher removed a 2014 article that seems to have merely changed the title and authors of a 2013 article  from another journal. When … Continue reading Publisher bans authors for apparent plagiarism

Predatory journals published 400,000 papers in 2014: Report

The number of so-called “predatory” open-access journals that allegedly sidestep publishing standards in order to make money off of article processing charges has dramatically expanded in recent years, and three-quarters of authors are based in either Asia or Africa, according to a new analysis from BMC Medicine.* The number of articles published by predatory journals spiked … Continue reading Predatory journals published 400,000 papers in 2014: Report

Re-analysis of controversial Paxil study shows drug “ineffective and unsafe” for teens

The antidepressant Paxil isn’t safe or effective for teens after all, says a re-analysis of a 2001 study published today in The BMJ. The original 2001 paper in Journal of the American Academy of Child and Adolescent Psychiatry — study 329, as it’s known — helped greenlight use of the drug (generically known as paroxetine) in young people. … Continue reading Re-analysis of controversial Paxil study shows drug “ineffective and unsafe” for teens

“Fabricated results” retract JAMA clinical trial, plus a sub-analysis of the data

A JAMA clinical trial that suggested a blood pressure drug could help patients increase their physical fitness, and a sub-analysis of those data, have been retracted after “an admission of fabricated results” by the first author on both papers. The three-year clinical trial was published in JAMA in 2013.  It was retracted this morning. The trial found … Continue reading “Fabricated results” retract JAMA clinical trial, plus a sub-analysis of the data

Cancer drug paper nulled by “statistical errors”

Researchers have pulled a paper about a drug used to treat pancreatic tumors due to “statistical errors.” The 2014 paper suggested a drug that appears to treat pancreatic tumors also works in Chinese patients. We’re not exactly sure what went wrong with “A randomized phase II study of everolimus for advanced pancreatic neuroendocrine tumors in Chinese patients,” however, because … Continue reading Cancer drug paper nulled by “statistical errors”

“Exactly the same clinical study” published six times

A group of researchers conducted a clinical trial on hundreds of hypertensive patients. Then, they published the results…six times. The “nearly identical” papers came to our attention via a retraction in Inflammation. Editor in chief Bruce Cronstein explained how he learned of the mass duplication: The editors were contacted en masse by somebody doing a Cochrane Review … Continue reading “Exactly the same clinical study” published six times
