Several recent studies had concluded that the risk of gastric cancer doubled with the use of drugs such as omeprazole – proton pump inhibitors. A new study published in The BMJ states that there is no association between prolonged use of these drugs and the risk of gastric adenocarcinoma. The research used prospective data from registries in Denmark, Finland, Iceland, Norway, and Sweden between 1994 and 2020. The study included more than 17,000 patients with gastric adenocarcinoma (other than cardia cancer) who had been exposed to these drugs for more than one year.
The Human Cell Atlas, an international research consortium, publishes biological data from different cell types in the human body in a series of articles in Nature and other journals in its family. One of the articles integrates single-cell RNA sequencing datasets from the gastrointestinal tract of healthy people and others with different diseases. It describes inflammation-induced changes in stem cells that alter mucosal tissue architecture and promote increased inflammation, a concept that can be applied to other tissues and diseases.
