JAMA vitamin-hip fracture study earns Expression of Concern for integrity issues

with 4 comments

jama coverJAMA has issued an Expression of Concern about a 2005 study of whether two different types of vitamin B could prevent broken hips in people who’d suffered strokes.

The original study concluded:

In this Japanese population with a high baseline fracture risk, combined treatment with folate and vitamin B12 is safe and effective in reducing the risk of a hip fracture in elderly patients following stroke.

Here’s the notice for the study, “Effect of folate and mecobalamin on hip fractures in patients with stroke: a randomized controlled trial:” Read the rest of this entry »

Clinical trial of Achilles tendon therapy retracted for not actually being a clinical trial

without comments

JBJS_ak6The Journal of Bone and Joint Surgery has retracted a 2012 paper because of ethical violations, initially flagged by the journal in 2013.

The study, which examined the use of autologous cell therapy in treating Achilles tendinosis, claimed in its abstract to have “conducted a randomized, double-blind study on forty Achilles tendons in thirty-two patients.” Apparently, though, it wasn’t actually a clinical trial but was somehow, according to the retraction notice, “misclassified” as such “in error.”

The problem was originally flagged by the UK’s Medicines and Healthcare products Regulatory Agency, which wrote the journal to tell them that it hadn’t granted ethical approval for the study, as we reported in 2013. At the time, there was a question about whether the lead author had retained records of the results, which is addressed in the retraction notice, signed by editor-in-chief Marc F. Swiontkowski and editor-in-Chief Emeritus Vernon T. Tolo: Read the rest of this entry »

BioMed Central retracting 43 papers for fake peer review

with 20 comments

bmc logoBioMed Central is retracting 43 papers, following their investigation into 50 papers that raised suspicions of fake peer review, possibly involving third-party companies selling the service.

In November 2014 we wrote about fake peer reviews for Nature; at that point there had been about 110 retractions across several journals. The addition of 16 retractions by Elsevier for the same reason, and today’s 43 from BMC, brings retractions resulting from the phenomenon up to about 170.

BMC has also contacted institutions regarding 60 additional papers that were rejected for publication, but seem to be part of the same kind of scam. Regarding the third-party agents, BMC senior editor of scientific integrity Elizabeth Moylan writes: Read the rest of this entry »

At the time, we were waiting on the third retraction, in the journal Orthopedic Reviews. It has now arrived.

The article was titled “Open reduction and internal fixation of displaced clavicle fractures in adolescents,” and Hosalkar wrote it with Gaurav Parikh, James D. Bomar and Bernd Bittersohl. Read the rest of this entry »

Tokyo panel calls for retraction of 43 Kato papers

without comments

katoThe University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.

If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]

The Asahi report quotes Kato — who has received some $20 million in government funding for his work  — as acknowledging problems with the data in his studies: Read the rest of this entry »

Three retractions, two lawsuits, one institutional inquiry for San Diego orthopedic surgeon

without comments

11832_5_2_OC.inddThree retractions, two lawsuits, one institutional inquiry. That’s not the kind of math anyone likes to do — but it’s the tally for Harish Hosalkar, a San Diego surgeon specializing in pediatric orthopedics.

Hosalkar became embroiled in a messy affair after problems surfaced in data he had published while at Rady Children’s Hospital — a facility he left under a cloud of recriminations. More on that in a bit. Read the rest of this entry »
