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Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed.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

Check List, the “journal of species lists and distribution,” retracted a paper in February after the authors realized they hadn’t spotted a yellow-red rat snake in a strange range, but rather a green rat snake in its known home.

Here’s the notice for “New distribution and elevation records for the snake Pseudelaphe flavirufa Cope, 1867 (Squamata: Colubridae) in Oaxaca, Mexico,” as written by the authors: Continue reading Rats! Snake mistake sinks paper

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

Although we could try to explain this, we’d rather leave it up to Giacomo Vianello, an experimental physicist at Stanford University, who was a member of the research team.

Vianello told us: Continue reading Twinkle, twinkle little star, how I wonder where you went: Astronomy report retracted

Authors retract Current Biology study following criticism on PubPeer and university investigation

current biologyThe authors of a Current Biology paper published online in February of this year have retracted it after voluminous criticism on post-publication review site PubPeer and a university committee found evidence of figure manipulation.

The paper, “Agonist-Induced GPCR Shedding from the Ciliary Surface Is Dependent on ESCRT-III and VPS4,” was co-authored by Hua Jin and Livana Soetedjo, a graduate student in Jin’s lab. Soetedjo was first author, and Jin was corresponding author.

The comments at PubPeer began on March 24: Continue reading Authors retract Current Biology study following criticism on PubPeer and university investigation
