A shooting at CDC, and a regulator returns to FDA

A lot of news took place this weekend at the federal health agencies. Here's what you need to know:

A gunman attacked the main campus of the CDC in Atlanta on Friday, further shaking an agency in the midst of a tumultuous year. The shooter had blamed the Covid-19 vaccine for making him ill. STAT's Daniel Payne wrote about what happened and the initial reaction of agency staffers. 

On Saturday, Daniel and Helen Branswell reviewed a recording of an internal call in which CDC employees recounted emotional, harrowing experiences and asked questions about "misinformation" that may have influenced the shooter as well as about health secretary Robert F. Kennedy Jr.'s response to the crisis. Read more about the concerns. 

Former surgeon general Jerome Adams writes in a First Opinion essay that the shooting "is not an isolated event," but rather "a dire reflection of ever-escalating threats public health workers face in a climate increasingly shaped by misinformation, politicization, and inflammatory rhetoric." Read the essay.

Meanwhile, at the FDA: STAT's Lizzy Lawrence reviewed recordings of two recent meetings in which employees pushed leadership for answers on whether the agency would restore funding for research fellows, when they will be allowed to easily attend conferences again, and why FDA's leaders are holding ad-hoc panels including experts with clear conflicts of interest. Read about the meetings.  

That was Friday. On Saturday, we learned that Vinay Prasad is returning to the FDA to resume his role overseeing vaccine, gene therapy, and blood product regulation. (He left a mere two weeks ago.) Prasad's return indicates that the administration considers him critical to their health policy goals, Lizzy reports, despite political backlash. It's also yet another sign of turbulence within the FDA. Read more.

Trump tries to rewrite research funding rules

On Thursday night, President Trump signed a sweeping new executive order that seeks to transform how the federal government awards billions of dollars in research grants by giving political appointees unprecedented power over the projects agencies fund. Instead of experts and career civil servants setting funding decisions and priorities, the order places that authority with presidential appointees who, in coordination with the White House, are directed to use their "independent judgment" and "advance the President's policy priorities."

The executive power grab, which experts expect to be challenged in court, is likely to have massive and immediate impacts on the daily operations of American science. Read more about it from STAT's science team.

YIMBY says what?

In all the conversation about industry concentration in health care — meaning the way that small clinics and hospitals are gobbled up by a smaller number of health systems — one question is rarely considered. How easy is it for new providers to jump into the fray by opening their own practice?

It's too hard, according to Dan O'Neill, who has spent the last four years helping to build a new primary care practice in California, Nevada, and Arizona. There's an administrative gauntlet that providers must navigate, and if they don't make it through, the care doesn't get delivered. Read more in O'Neill's First Opinion essay, in which he explains specific problems his business faced with some familiar names like Medicare Advantage and UnitedHealth Group.

How UnitedHealth protects its Medicare profits

A study published in a major medical journal earlier this year showed that UnitedHealth's preferred approach to covering Medicare patients, an especially profitable line of business, was producing higher-quality care for older Americans than the standard method. Good news for everyone, right? Not quite. The paper's key finding seems to be a statistical mirage, due to flaws in its methodology, according to 13 independent experts who reviewed the manuscript for STAT.

A STAT examination found the study was one of a handful of research publications, including peer-reviewed studies and white papers, that UnitedHealth and a web of business partners and lobbyists have used to bend the debate over Medicare Advantage in their favor. Hanging in the balance is a $550 billion pot of federal money that is crucial to UnitedHealth's financial performance. Read more in the eighth installment of Health Care's Colossus.

70%

That's how much higher the risk of cardiovascular disease is for women who have had to obtain a restraining order against somebody as compared to those who haven't. For women who have experienced being stalked, risk is 41% higher than those who haven't. That's according to a study published today in Circulation, in which researchers analyzed two decades of data from more than 66,000 women enrolled in a nurse health study. Increased risk was maintained after accounting for other factors like parental history of cardiovascular disease. 

Stalking is one of the most common forms of violence that women in the U.S. experience. The results indicate an urgent need to consider violence against women in a public health context.

How a dietitian became Instagram's top MAHA critic

You know how people say luck is when preparation meets opportunity? Some might say Jessica Knurick was lucky when the Make America Healthy Again movement began emerging online last summer. "It was my exact area of expertise, looking at policy and how policy impacts chronic disease," said Knurick, a registered dietician with a Ph.D. in nutrition science. "And it was just very easy for me to see how manipulative the narrative was."

For a couple years, Knurick had been posting videos combatting pregnancy misinformation. Then, noticing the parallels between the pregnancy content she was served online and MAHA's rhetoric about synthetic dyes and seed oils, she began posting educational videos about the movement — and her Instagram account skyrocketed from around 150,000 followers to over a million. Read more from Sarah Todd about how Knurick practices the art of science communication.
