GLP-1s for recidivism?
A wave of clinical trials have begun to test the ability of GLP-1 weight loss drugs to quell various substance use disorders, with some promising results. A new trial announced yesterday will go further, testing the real-world impacts of weekly semaglutide injections, focusing on factors like a person’s involvement with the criminal justice system, employment, housing stability, and health care utilization. This is a large, major study, and as I continue covering addiction for Lev, it’s definitely something I’ll be keeping an eye on. If a strong connection is found, the results could be used to advocate for more public investment in the medication.
The trial is a collaboration between the Center for Addiction Science, Policy and Research (a nonprofit focused on GLP-1s for addiction treatment) and the Allegheny County Department of Human Services in Pennsylvania. Set to begin in early 2027, the study will enroll up to 1,200 participants with alcohol use disorder, opioid use disorder, or both. Researchers will use the county’s linked administrative data to track participant outcomes.

What’s in a baby’s gut microbiome?

The window between conception and a baby’s second birthday is critical for brain development. And there are all sorts of factors that contribute: genetics, sleep, interactions with parents, and more. A new First Opinion essay posits one more, suggesting that the gut microbiome may play a key role in brain developmental plasticity.
That’s important because autism, ADHD, and Alzheimer’s disease are all impacted by plasticity. What’s happening in a baby’s brain at a few months old could, as the essay authors put it, “influence whether she can still recognize a face across a room at 80.”
Scientists at Wellcome Leap’s FORM (where one author, Holly Baines, leads research) are investigating if accumulating pressures on the developing gut microbiome — variables like c-sections, antibiotics use, and formula feeding — may contribute to rising neurodevelopmental differences. Read more on where the science is now and what’s ahead.
