Introducing peanut-containing foods to infants can dramatically reduce the risk of peanut allergies later in childhood. But many parents — particularly those who are Black, Hispanic, lower-income or have less formal education — aren’t receiving this potentially lifesaving guidance from their pediatrician and are introducing peanuts at much lower rates, reports a large new Northwestern Medicine study.

Researchers found that tirzepatide, a medication primarily used for treating type 2 diabetes and weight loss, reduced body weight, food intake and many measures of appetite more than placebo and liraglutide. These results were recently published in Nature Medicine in the study titled “Tirzepatide on ingestive behavior in adults with overweight or obesity: a randomized 6-week phase 1 trial.”

The value of a recent biochemical discovery can be seen in the case of an 8-year-old boy, who was playing typical sports in August 2023, but by November needed a wheelchair because of a rare disease that caused worsening paralysis. As part of a new study, neurologists at NYU Langone Health treated the boy with an experimental compound that partially reversed his rapid decline. Two months after beginning treatment, he was able to walk long distances again and even run.
