Good morning. If you haven't seen Alex Hogan's STATus Report video on the CDC vaccine committee's vote regarding the hepatitis B birth dose, please take a few minutes to watch over your coffee this morning. The whole series has been a real joy to follow this year — not something you can always say about constantly shifting health care news. Watch some of the previous videos here.

House passes bill banning trans care for youth 

Republicans in Congress are making a renewed push before the end of the year to pass major federal restrictions to gender-affirming care for trans minors. Last night, by a vote of 216 to 211, the House passed a bill that aims to prohibit doctors from providing any gender-affirming care to minors by amending an existing statute on female genital mutilation. 

It’s one of two bills focused on pediatric gender-affirming care that the House plans to consider this week, before lawmakers depart for their holiday break. The other would ban Medicaid from funding that care for minors. 

“It’s been an all-hands-on-deck effort to restrict this access,” Lindsey Dawson, director of LGBTQ Health Policy at KFF, told me. Read more on how representatives are talking about the bills and what we know about the next moves.

And my colleague John Wilkerson has the details on another bill passed last night, which aims to boost access to workplace insurance.

LA fires mixed wild and urban fuel — and reasons for ER visits

Almost a year ago, wildfires swept through Los Angeles, devastating vast swaths of the city and county. And those blazes posed a special danger to the city’s residents. Fires that kindle in the wild but then burn urban landscapes, spread more widely and, once out of the woods, consume a more varied fuel that includes cars, buildings, and whatever’s inside them. As a result, the pollution they produce is different, too. 

That could have long-term health impacts, researchers are finding. A new paper in JACC tracked visits from people in ZIP codes near the fires to the Cedars-Sinai Emergency Department, located about 10 miles from the Pacific Palisades and about 20 miles from Altadena. The researchers compared illnesses and patient numbers to those from the same 90 days from 2018 through 2024.

Significantly more people developed heart attacks (46%), lung complications (24%), and general illnesses (218%) through the first week of April this year, the researchers found. 

Hearts and lungs are especially vulnerable to the fine particles created by wildfires, so that increase was not surprising, but the doubling of other illnesses and signals in the bloodstream stood out, something not previously reported after other fires. Symptoms included abdominal pain, fainting, and shortness of breath along with lower respiratory illnesses, high blood pressure, head injury, and sepsis.

“Abnormal blood test results could indicate that the body is responding to an external stressor such as toxins in the air,” study co-author and cardiologist Joseph Ebinger said in a statement. “We need more research to determine what we can do to mitigate any remaining risks and protect people from fire harm in the future.” — Elizabeth Cooney

NIH falls silent as eugenic ideas spread

NIH/NHGRI

The National Human Genome Research Institute is the NIH’s only institute dedicated not to an organ or a disease, but to a molecule. And not just any molecule. DNA represents our fascination with the questions of how, and why, humans differ. Because of that, modern geneticists have also been forced to confront how their work has at times perpetuated scientific racism and the myth of race as a biological category. At NHGRI, that work was happening. Then its staff was gutted.

“Being willfully neglectful of preserving the past is just insane to me, as a historian and as somebody that values the preservation of that kind of data and information,” said Zach Utz, who served as the archivist at NHGRI from 2018 until he was laid off in April. 

In the ninth installment of American Science, Shattered, STAT’s Megan Molteni and Anil Oza present a case study of the Trump administration’s efforts to eviscerate subject matter expertise and throttle public information-sharing at the NIH. It’s based on interviews with 10 former and five current agency employees, along with more than 100 internal NIH emails, memos, and other documents. Read the story

Why are employers dropping coverage for weight loss drugs?

Experts who spoke to STAT’s Elaine Chen say they’re increasingly hearing about companies cutting blockbuster weight loss drugs out of health plans for next year. The growth of direct-to-consumer cash offerings from the drugs’ manufacturers, Eli Lilly and Novo Nordisk, may play a role in this shift. 

HCA Healthcare, one of the largest hospital systems in the U.S., recently told employees it would stop covering the drugs, pointing them to that alternative. To Craig Garthwaite, director of health care at Northwestern University’s Kellogg School of Management, this read as: “‘I’m gonna direct you to this manufacturer plan, because for me as a company, that’s a lot cheaper than me buying you the drug.’” Read more from Elaine about where this leaves workers. 

And in the meantime: More than three dozen state attorneys general are urging Meta to better enforce its policies to thwart a “surge of misleading” pharmaceutical and wellness ads for weight loss drugs on Instagram and Facebook.

New York Giants doc calls out regenerative medicine

As head team physician for the New York Giants, Scott Rodeo is regularly asked by athletes about the “breakthrough” stem cell treatments they’ve seen promoted at offshore clinics in Panama, Colombia, and other countries. It sounds like the future of medicine people have long dreamed about, but in a new First Opinion essay, Rodeo brings a dose of reality to the conversation. He’s seen the harm that can come after “miracle injections” or an expensive trip abroad for “next generation cell therapies.”

“As an orthopedic surgeon and researcher, I have to say what the ads won’t,” Rodeo writes. “Regenerative medicine isn’t there yet.” Read more on what he makes of the “Wild West atmosphere” around attempts at regulating these clinics.
