On Friday, two federal judges ruled that the Trump administration must continue to fund SNAP throughout the government shutdown. Do you receive SNAP benefits? How are you holding up a few days into November? Reach out: theresa.gaffney@statnews.com

Yesterday, STAT's Lizzy Lawrence and Adam Feuerstein scored another exclusive: The FDA's top drug regulator has been placed on leave after being accused of using his regulatory authority to inflict financial harm on a former business associate. Read more and let's start the week.

An NIH-led study on structural racism?

Science is slow. A new paper linking structural racism to increased heart disease, published Friday in JAMA Health Forum, demonstrates this in a uniquely 2025 way. How? Several of the paper's authors are scientists at the NIH, whose director has in recent months discredited research on structural racism as "ideological" and "unscientific." 

But a comment like that "ignores both the evidence and the lived experiences of millions of people," said Charles Rogers, a study co-author and director of the Men's Health Inequities Research Lab. "The data are clear: Neighborhoods with higher levels of structural racism have worse cardiovascular health. Refusing to study that truth does not make it go away." Read more from STAT's Anil Oza on what the study found, and what it means in times like these.

A new study provides some clues on Covid, pregnancy, and autism

A study published in Obstetrics & Gynecology last week found that children born to mothers who had a Covid infection while pregnant were at higher risk of experiencing developmental disorders like speech delays, autism, and motor disorders by the time they were three. Researchers analyzed data from more than 18,100 live births that took place in a large Boston-area health system between March 2020 and May 2021. 

The authors highlight a strength of the research: Since the data is from early days of the pandemic, almost all of the participants were unvaccinated and "immunologically naïve" to the virus. But that raised a question for STAT's Helen Branswell: Is this association specific to a person's first infection? The incidence of conditions such as myocarditis and MIS-C have fallen away as Covid has become endemic. If this is a similar issue, then the increased risk found in the study could dissipate in the future, as practically nobody will be truly "naïve" to the virus like they were during the study period — especially by the time they're old enough to have kids.

Study co-author Roy Perlis acknowledged that this is possible, though he believes it unlikely. Another expert, epidemiologist Michael Osterholm, thought Helen's question was an important one, saying the theory "makes some sense, based on what we've seen with other neurological and immunological responses." And it's an important potential caveat given how people may interpret the results and worry about increased risk. It would be useful, he said, for the authors to go back and see if there were any changes in observed risk based on what point in the pandemic people were pregnant.

No assumptions can be made, Perlis said. "The U.S. is in the midst of an unfortunate experiment in what happens when we stop using safe and effective vaccines consistently," he added. "So it's likely we will continue to see Covid infections in infection-naive people, and these rates may even increase."

Canada leads the charge toward … losing measles-elimination status

When a country or region achieves measles-elimination status, meaning it has stopped endemic transmission of the disease, it's not exactly an easy badge to lose. A sick traveller returning home or a tourist bringing the virus in from elsewhere won't do it. But it's happened before in the Americas, the only region in the world that has ever managed to achieve elimination status. And it may be about to happen again.

This week, an expert committee will meet in Mexico City to study measles transmission data from the Americas. On the table for discussion is a large and long-running outbreak in Canada, threatening elimination status for both the country and the region. It's largely symbolic, but it would be a heavy loss for the first country to stop endemic spread of the virus in 1998. Read more from Helen on what scientists expect to happen at the meeting and why it matters.

How Texas became the (MAHA) heartland

At a farmers market, a customer uses a phone to pay for fresh produce

Jamie Carrero for STAT 

Over recent months, Texas has become a testing ground for health-related legislative efforts — which in some ways has been a long time coming. The state has a diverse population, a political establishment eager to please the Trump administration, and a colony of prominent Make America Healthy Again converts. In August, the governor sat shoulder to shoulder with health secretary Robert F. Kennedy Jr. as he signed a package of MAHA bills at a desk adorned with a blue placard reading "Making Texas Healthier."

The average Texan doesn't always know the MAHA movement by name, but it has undoubtedly taken root there. STAT's Isabella Cueto recently spent a week in the Lone Star state, talking both with people invested in the political movement and others who are simply trying to keep themselves and their families healthy. One pair of sisters particularly stuck with me — like many Americans, they're taking stock of MAHA and arriving at divergent views.

"Maybe some could label me a conspiracy theorist, but I'm open to learning," Alysha Bogie said. Her sister Amber recently had a baby, and Alysha has to wear a mask when visiting, since she isn't fully vaccinated. "As a new mom, I think you're just—," Alysha started. But Amber cut her off: "Overwhelmed? And terrified?" Read Isa's report from the ground.

A fluoride crackdown on Halloween

The FDA announced Friday that it will take action to restrict the sale of ingestible fluoride supplements. Leadership first previewed the move over the summer at a public meeting on the usage and potential risks of such products, which are typically recommended for kids in areas without fluoridated water. Now, the agency has sent notices to four companies outlining its intention to take enforcement action related to the supplements. 

"This Halloween, the FDA is driving a stake through the heart of outdated science … It's scary that these products have been used for decades without approval," Kennedy said in a statement released on what one STAT reporter described as "the candy-est day of the year." 

In the past, Kennedy has advocated for the removal of fluoride from water as an issue of medical freedom. But critics say that removing oral fluoride supplements from the market would restrict parents' freedom of choice. Revisit Anil's story from this summer to learn how we got here.

What's ahead at AHA

Later this week, physicians, researchers, patients, and patient advocates will gather in New Orleans for the scientific sessions of the American Heart Association, where they'll hear about new ways to address cardiovascular disease, the leading cause of death in the U.S. STAT's Elizabeth Cooney will be on the ground to cover the conference. Here's a preview of the science that will be presented in NOLA:

  • A new study suggests there are factors that start in the kidney and then lead to cardiovascular problems in people with advanced chronic kidney disease, independent of other issues.
  • Patients who survive a stroke caused by narrowed blood vessels live with a higher risk of another stroke or heart attack. Another study tells us the lower their LDL-C, or "bad" cholesterol fell, the better they did — even when that number dropped below recommended levels.
  • Men and women vary in how they develop and experience heart disease, from who's vulnerable to what symptoms they feel to who survives. A new study, published Monday in the Journal of the American Heart Association, asked how those sex differences play out across the United States in deaths from heart attacks.
