A new study by PECARN reveals that steroid treatment does not prevent hospitalization or improve symptoms in infants with bronchiolitis, the most common cause of infant hospitalization. The study's findings provide solid evidence for treating bronchiolitis with simple supportive care.
Biologics may be a valuable treatment option for inflammatory bowel disease (IBD), offering new hope for patients. However, gastroenterologists must carefully weigh the potential benefits against significant side effects and costs. Research is ongoing to better understand the role of biologics in IBD treatment.
Researchers propose new model for predicting post-hospital death risk in aortic dissection patients based on blood clotting in the false lumen. Partial clotting is associated with a much greater risk of death, while those with patent or completely thrombosed false lumens have intermediate and lower risks respectively.
A new NIH-supported study shows that obesity spreads within social networks, with closer connections increasing the influence on developing obesity. The study analyzed data from the Framingham Heart Study, finding that a person's chance of becoming obese increased by 57% if they had a close friend who became obese.
The Eli and Edythe Broad Foundation has awarded a three-year grant to the American Gastroenterological Association to support research fellowships for high school students interested in gastroenterology. The program will provide $2,500 each to five students to fund a 10-week research session under the supervision of an approved preceptor.
Large Humboldt squid have invaded the sea off Central California, where they are feeding on commercially important fishery species like hake and anchovy. This shift may be linked to a decrease in large tuna and billfish populations in the Equatorial Pacific, allowing the squid to expand their range.
A recent study by OHSU and VAMC researchers found that female mice are more susceptible to brain cell death after alcohol withdrawal than male mice.
