Two recent retractions hurt the credibility of both the peer review process and eminent medical journals, as published here.
In a time of fast and furious COVID-19 related manuscript submissions, we need to balance speedy publication review with quality control. Perhaps this special situation calls for fraud detection, which can be challenging. However, as with the recent case of Surgisphere and the New England Journal of Medicine, as previously blogged, when something seems too good to be true, it probably is a fraud.
Be exceedingly skeptical.
