Seven years after ‘noncompliance’ finding, whistleblowers push for retractions

VA San Diego

Seven years after investigations uncovered “serious noncompliance” in the collection of biological samples at a California VA hospital, the original whistleblowers say several papers related to the work use these problematic samples and should be retracted. But the principal investigator of the work says there’s no reason to question the findings.

The VA San Diego Health Care System was one of 12 institutions involved in the InTeam Consortium, a research initiative between 2013 and 2019 focused on alcohol-related liver inflammation. In 2016, two whistleblowers — Mario Chojkier and Martina Buck — alleged staff at the VA hadn’t obtained proper consent to perform biopsies on critically ill patients and use the samples for research related to the project. 

Subsequent investigations — including one by VA San Diego’s institutional review board — have confirmed violations of policies, primarily related to a lack of informed consent. Ramon Bataller, the principal investigator of the InTeam Consortium, told local media outlet inewsource in 2019 the samples collected at the VA would be “banished” from any academic papers

A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication

ddsComing back up?

Digestive Diseases and Sciences has retracted two papers for duplication.

The first paper, “Membrane-Bound Mucins and Mucin Terminal Glycans Expression in Idiopathic or Helicobacter pylori, NSAID Associated Peptic Ulcers,” was published in October 2012 by a group from Israel and the United States. It found that:

Cytoplasmic MUC17 staining was significantly decreased in the cases with idiopathic ulcer. The opposite was demonstrated for MUC1. This observation might be important, since different mucins with altered sialylation patterns likely differ in their protection efficiency against acid and pepsin.

But, as the retraction notice suggests, that much had been found before: Continue reading A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication
