![]() pylori infection can result in the formation of peptic ulcers - open sores in the lining of the stomach and duodenum. Previous studies have demonstrated a strong link between the occurrence of peptic ulcers in patients receiving low-dose aspirin - usually up to 100 milligrams (mg) daily, but may reach 325 mg daily - and the presence of Helicobacter pylori, a bacterium that infects the stomach. A 2021 clinical trial that enrolled 19,114 participants aged 70 years or older found that aspirin increases the risk of significant gastrointestinal bleeding by 60%. The main disadvantage of aspirin use is the risk of serious gastrointestinal bleeding, which can occur even at low doses. By thinning the blood, aspirin reduces the risk of blood clotting and may prevent a heart attack or a stroke. Thanks to its wide range of medicinal benefits, aspirin is one of the most commonly used medications in the world.įor decades, aspirin has been used for the prevention of cardiovascular events in patients with heart disease. These findings demonstrate a new gastroprotective strategy for long-term aspirin users and pave the way for further research on the health benefits of aspirin.They found that eradication of the bacterium protects against ulcer bleeding, but this protection appears to be lost over time.pylori with a short course of antibiotics would prevent ulceration and bleeding. Researchers investigated whether the eradication of H.Helicobacter pylori infection is linked to peptic ulcers and long-term aspirin use increases the risk of ulcer bleeding.The study hinges on data collected by a team led by first author Shfaqat Abbas Khan, a professor at DTU Space, using a network of GPS stations that stretch inland on the NEGIS to behind the Nioghalvfjerdsfjord Gletscher and Zachariae Isstrøm glaciers, one of Earth’s most hostile and remote terrains.Share on Pinterest How can doctors help reduce the risk of stomach bleeding associated with aspirin use?

Morlighem led the development of the numerical models for the study that simulated the flow of ice from the interior of the ice sheet to the coast. “Many glaciers have been accelerating and thinning near the margin in recent decades-GPS data helped us detect how far inland these changes happening near the coast propagate,” said Morlighem, the Evans Family Distinguished Professor of Earth Sciences at Dartmouth. MATHIEU MORLIGHEM, EVANS FAMILY DISTINGUISHED PROFESSOR OF EARTH SCIENCES The Greenland ice sheet is not necessarily more unstable than we thought, but it may be more sensitive to changes happening around the coast. ![]() The researchers found that this thinning stretches up to nearly 200 miles inland from the Greenland coast-and that other glaciers on Greenland may be suffering the same fate. In 2012, the intrusion of warm ocean currents caused the floating extension of the NEGIS to collapse, which has accelerated ice flow and triggered a wave of rapid ice thinning that has spread upstream. The study combined satellite data and numerical modeling with GPS data collected from the harsh interior of Greenland over the past decade. 9 in the journal Nature that the Northeast Greenland Ice Stream, known as NEGIS, could add a half-inch or more of water to sea levels by the end of this century, which is equivalent to the entire Greenland ice sheet’s contribution during the past 50 years. ![]() (Photo courtesy of Shfaqat Abbas Khan, DTU Space) Co-authors Shfaqat Abbas Khan and Anders Bjork work near a river of meltwater on the remote Zachariae Glacier in Northeast Greenland. ![]() The loss of ice from Greenland’s largest basin is occurring much faster and could contribute up to six times more to global sea-level rise by 2100 than climate models currently project, according to a study led by Dartmouth professor Mathieu Morlighem with researchers from the Technical University of Denmark (DTU) and the University of California, Irvine. ![]()
