Alleged Medicare cheat loses paper for data mix-up

A Boston doctor indicted on charges of Medicare fraud in 2007 has had a paper relating to the case retracted this month.

Abdul Razzaque Ahmed was considered something of a miracle worker by his patients, treating two rare and disfiguring skin conditions called pemphigoid and pemphigus vulgaris. He used more powerful medicines than the typical course of treatment, including a drug normally used to treat cancer.

The initial indictment stated that Ahmed mixed blood samples to falsely show a “dual diagnosis” of both diseases, and prove to Medicare that they required the more rigorous (and expensive) treatment. It also alleged that he profited massively from the government pay-outs. He was convicted of obstruction in 2007; the other charges were dropped when he agreed to forfeit assets worth $2.9 million.

Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed. Here is the retraction notice from Clinical Immunology: Continue reading Alleged Medicare cheat loses paper for data mix-up

The journal Blood has retracted a 2010 paper over the objections of most of its authors, two of whom were found by their university to have used “fraudulent methods” to obtain the data.

We first reported on the case of Gerold Feuer last fall. The State University of New York (SUNY) Upstate Medical Center in Syracuse fired Feuer in 2010 after determining that he had misused state funds to enrich a company he had founded, HuMurine. A court agreed with many of the university’s claims, but ordered his reinstatement in 2012.

Meanwhile, as we noted last fall: Continue reading Journal retracts stem cell study despite objections of most authors

Dispute with “unlisted author whose claim to authorship could not be solved” topples cancer paper

cancreschCancer Science, the journal of the Japanese Cancer Association, has retracted a 2012 article by a group of researchers because, well, it wasn’t clear who made up the group in the first place.

The article,  “Antitumor activity of human γδ T cells transducted with CD8 and with T-cell receptors of tumor-specific cytotoxic T lymphocytes,” appeared online in July 2012 and was written, ostensibly, by Takeshi Hanagiri, Yoshiki Shigematsu, Koji Kuroda, Tetsuro Baba, Hironobu Shiota, Yoshinobu Ichiki, Yoshika Nagata, Manabu Yasuda, Tomoko So, Mitsuhiro Takenoyama and Fumihiro Tanaka from the Second Department of Surgery at the University of Occupational and Environmental Health, in Kitakyushu.

Faked HIV vaccine research presentation retracted

retrovirologyIn December, we reported on the case of Dong-Pyou Han, who was found by the Office of Research Integrity to have spiked rabbit blood samples to make it look as though a vaccine for HIV was working.

At the time, Han’s former institution, Iowa State, told us that “one oral presentation and some abstracts will be removed from the web.”

One of those retractions has occurred, in Retrovirology, of “Eliciting broadly neutralizing antibodies against HIV-1 that target gp41 MPER.” Here’s the notice: Continue reading Faked HIV vaccine research presentation retracted

Expression of Concern reveals journal editors bending over backward to give authors benefit of the doubt
