The journal Neurology has issued an Expression of Concern over recommendations it published earlier this year regarding the treatment of multiple sclerosis.
The journal’s website received multiple comments from clinicians expressing their own concern about the flawed recommendation, which was published as part of a paper titled “The American Academy of Neurology’s Top Five Choosing Wisely recommendations.” The problematic item was number 4: Read the rest of this entry »
Two Expressions of Concern in Blood for MD Anderson’s Aggarwal, who has threatened to sue Retraction Watch
Bharat Aggarwal, the MD Anderson researcher who has threatened to sue us while under investigation by his institution for alleged misconduct, now has two Expressions of Concern in addition to two corrections and two unexplained withdrawals.
Both of the papers were published in Blood. The Expression of Concern for “Gambogic acid, a novel ligand for transferrin receptor, potentiates TNF-induced apoptosis through modulation of the nuclear factor-κB signaling pathway,” reads: Read the rest of this entry »
BMC Genomics has issued an expression of concern for a 2011 paper by a prominent Argentine chemist, Ariel Fernandez, whose work covers several disciplines — “His research spans representation theory in algebra, physical chemistry, molecular biophysics, and more recently, molecular evolution and drug discovery” — and institutions. And therein lies the tale.
Fernandez appeared as the first author of the article, titled “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances,” along with a pair of researchers from Taiwan. Fernandez’s affiliations were listed as being with the Instituto Argentino de Matemática “Alberto P. Calderón”, CONICET (National Research Council of Argentina), in Buenos Aires, the Department of Computer Science at the University of Chicago, and the Morgridge Institute for Research, in Madison, Wisc.
According to the abstract:
ORI, OHRP find “some human subject issues” in Henschke lung cancer studies, but no evidence of misconduct
We have an update on two papers about lung cancer screening by Claudia Henschke and colleagues that were subject to an Expression of Concern early last year.
The original Expression of Concern in Cancer read, in part: Read the rest of this entry »
PLOS ONE has issued a fascinating expression of concern about data collection in a paper it published late last year on the possible spread of deadly viruses among Indonesian orangutans. The case has been brought to the attention of the Indonesian government, but more on that in a moment.
The article, published last July by an international group of primate scientists led by Chairul Nidom, a virologist at Indonesia’s Airlangga University, sounded an alarm about “wild” orangutans in Borneo: Blood tests of 353 “healthy” animals showed antibodies for viruses akin to Ebola. What’s more, the filoviruses viruses to which the antibodies responded, as New Scientist and other outlets reported when the original paper came out, included strains not previously seen outside Africa (as well as Marburg, another deadly infection).
The Journal of the American College of Cardiology, or JACC, has issued expressions of concern for three papers by Don Poldermans, the Dutch cardiologist who was fired earlier this year amid allegations of misconduct.
Cardiobrief’s Larry Husten had the story first.
The, um, heart of the matter is that neither the investigators at Erasmus Medical Center, Poldermans’ former institution, nor the JACC editors, can say whether the researchers conduct rose to the level of fabricating data. As the Notice of Concern states: Read the rest of this entry »
