STAT+: Oregon hospitals won’t outsource to national physician chain after all

After a tidal wave of blowback that culminated in a lawsuit, a nonprofit health system has reversed course in its plan to replace its Oregon emergency physicians with a national chain. 

PeaceHealth’s announcement Wednesday didn’t disclose what prompted its change of heart, but those familiar with the situation say it’s because the health system’s plan was poised for defeat in a legal challenge. When PeaceHealth said in February it was cutting ties with Eugene Emergency Physicians, the local group that had staffed its Oregon hospitals for 35 years, the news drew tremendous pushback from doctors, nurses, lawmakers, mayors, and emergency medicine groups. 

Then, on March 20, the Eugene emergency physicians sued, arguing that PeaceHealth’s plan to use the Atlanta-based staffing chain ApolloMD violated a new Oregon law prohibiting managed service organizations from directly owning medical practices or interfering with clinical decisions. The case has had four hearings, in which the judge was “quite clear” that the scheme violated the law, Senate Bill 951, said Hayden Rooke-Ley, an attorney who represented the doctors and a senior fellow for health care with the American Economic Liberties Project.

Trump administration’s drug strategy is at odds with recent actions on funding, policy

The White House’s new strategy for addressing the nation’s drug crisis calls for a number of consensus public health measures: the overdose-reversal medication naloxone, medication-assisted treatment, and test strips used to detect fentanyl or other drug supply adulterants. 

But the May 4 document appears to run counter to many of the Trump administration’s latest drug policy actions. In particular, it comes just days after the administration issued new restrictions on using federal dollars to distribute test strips and warned against the use of medication-assisted treatment unless accompanied by other services, like counseling.

At-Home Blood Test Screens for Early Dementia

A simple finger-prick blood test at home combined with online cognitive tests can reveal signs of Alzheimer’s disease, providing a convenient way to screen for early dementia.

The postal blood test, outlined in Nature Communications, is used to measure levels of two blood biomarkers linked with cognitive function: phosphorylated tau at amino acid 217 (p-tau217) and Glial Fibrillary Acidic Protein (GFAP).

It could provide a way to screen for dementia at home and act as a triage resource to identify those at risk earlier and tailor treatments more effectively, particularly in remote or unsupervised settings.

“This work raises the potential for screening people for their risk without the need for clinic visits or complex clinical assessments,” said lead researcher Anne Corbett, PhD, from the University of Exeter.

“It would ensure the people at highest risk could be prioritized for monitoring and diagnosis, unlocking the best support and treatment for those that need it most.”

While blood biomarkers are increasingly being used to diagnose Alzheimer’s disease, scalable tools are needed to reach the 99% of individuals with early cognitive impairment who are not seen in specialist healthcare services.

In an attempt to develop these further, Corbett and team conducted a study involving 174 people, of whom 146 had normal cognition and 28 had dementia.

All were participants in the PROTECT study, a larger investigation of more than 30,000 adults that aims to understand how healthy brains age and why people develop dementia.

Blood samples were collected at home using self-administered capillary blood tests, which were sent for p-tau 217 and GFAP lab testing. Venous blood samples were also available for 40 patients.

p-tau217 has previously been highly accurate at detecting Alzheimer’s disease pathology and is approved by U.S. regulators for symptomatic patients undergoing investigation for cognitive complaints.

GFAP is associated with broader cognitive decline and has been shown to be associated with Aβ deposition and progression of mild cognitive impairment to Alzheimer’s disease.

Brain performance tests were found to correlate with levels of both proteins, with p-tau217 showing the strongest association.

Capillary p-tau217 was significantly higher in people with dementia compared to those without and was significantly associated with cognitive performance and function.

A combination of an 85% specificity threshold for capillary p-tau217 85% and episodic memory performance one standard deviation (SD) below benchmarked norms identified 9% of participants who were at potentially high risk, and who also showed significantly higher impairment in cognition and function.

Importantly, this threshold for impairment of episodic memory indicated a much milder level of impairment than the 1.5 SD change required to identify people with mild cognitive impairment, revealing its potential ability to spot signs at a preclinical stage.

Unexpectedly, even though ptau217 and GFAP both identified individuals with cognitive impairment, there was only a modest overlap in individuals who were positive for both GFAP and p-tau217, with GFAP identifying a different group of at-risk individuals. GFAP biomarker appeared to be associated with vascular risk, unlike p-tau217.

Researcher Clive Ballard, MD, PhD, also at Exeter, said: “Our approach of combining our robust cognitive testing with measuring proteins via a postal blood test could provide a straightforward, efficient and cost-effective method to reach large numbers of people in the community who would not otherwise be prioritized for the next steps of diagnosis or support and to optimize the clinical pathway to enable early detection of those at highest risk.”

STAT+: Administration report on most favored nation drug pricing raises new details — and questions

WASHINGTON — The Trump administration on Tuesday released the most detailed look to date at its drug pricing policy and its purported impact, claiming huge future savings from the program.

The report, from the administration’s own Council of Economic Advisers, lays out the definition of “most-favored nation” pricing. That’s the definition pharmaceutical giants agreed to in their confidential deals with the administration, a White House spokesperson told STAT in an email. The most-favored nation pricing calculation represents a key underpinning of one of the White House’s top election-year talking points — though many key details of the deals remain private, and their ultimate impacts for consumers uncertain.

The analysis estimated the drug companies’ pledge to offer all new drugs at most-favored nation pricing would save the U.S. $529 billion over the coming decade — though the projection comes with big caveats.

Comparing Usual Care With Coordinated Clinician and Patient Use of Mobile Technology in Primary Care for Patients With Major Depressive Disorder: Practice-Based Pilot Study

Background: Major depressive disorder (MDD) affects millions of Americans each year and is often diagnosed and treated in primary care. Evidence shows that self-management techniques, shared decision-making (SDM), and goal setting are effective strategies for managing MDD, but the required collaboration between patients and primary care clinicians can be difficult. Primary Care Path is a program for supporting depression management in primary care that includes a patient-facing mobile app and an accompanying care team–facing web interface. Leveraging programs that provide clinician-facing software with companion patient-facing mobile technology may help patients and physicians align depression treatment and management goals, support effective SDM, alleviate barriers, and improve both clinical care and patient outcomes. Objective: To pilot-test the use of Primary Care Path for MDD management in primary care and evaluate the impact of its use on depression treatment, symptoms, goal setting and attainment, and SDM. Methods: Four primary care clinical practices in the United States were assigned to program use (2 practices; intervention) versus usual care (2 practices; control). Intervention practices used the Primary Care Path program in their clinics and engaged patient participants in app use for 18 weeks. Clinical care teams engaged with the patient-informed program portal primarily during patient encounters (in-person, virtual or calls). Patient participants were smartphone users aged 18 years and older who were being treated for MDD. Patient participants received online surveys (medication changes, Patient Health Questionnaire-9 [PHQ-9], goal setting and attainment questions, and Shared Decision-Making Questionnaire-9 [SDM-Q-9]) at baseline, 6, 12, and 18 weeks. Results: A total of 76 patient participants (34 intervention; 42 control) were enrolled; the majority were female (27/34, 79%; 32/42, 76%), White (31/34, 91%; 40/42, 95%), non-Hispanic/Latino/a (29/34, 85%; 40/40, 100%), and employed (26/34, 77%; 34/42, 81%). Control patient participants’ conversations with their medical providers increased over the study period, while intervention patient conversations with their medical providers decreased over time. At week 18, intervention participants felt more successful than control in achieving their personalized treatment goals. More intervention patient participants initiated antidepressant medication by weeks 12 (=.03) and 18 (=.04) and switched medications by weeks 6 (=.009) and 12 (=.04) versus control. All patient participants demonstrated significant improvement in PHQ-9 scores throughout the study period (<.001), with no difference in change by group. Clinicians and patients indicated using the program to support SDM, but no significant differences were observed in SDM-Q-9 between intervention and control. Conclusions: Preliminarily, the use of this digital health program related to earlier medication optimization, earlier conversations between patients and medical providers, and patient attainment of goals that matter most to them, indicating that coordinated use of the program by both patients and clinical team members may enhance MDD management in primary care clinical settings.

STAT+: Sanofi asks to pull diabetes drug out of FDA voucher program after political appointee interfered with review

WASHINGTON — Sanofi has asked the Food and Drug Administration to pull its type 1 diabetes drug, teplizumab, out of Commissioner Marty Makary’s new speedy drug review program. 

The move comes after acting Center for Drug Evaluation and Research Director Tracy Beth Høeg disagreed with a staff decision to approve the drug, according to sources familiar with the dispute who requested anonymity due to fear of reprisal. The agency has missed its goal date of April 21 to deliver a decision to Sanofi.

Such decisions are typically made by career scientists. It’s rare for a center director to become involved in scientific review of a single drug, and particularly a political appointee like Høeg. Makary recently told CNBC that he stands behind review teams, and that “disaster” occurs whenever political leaders overrule scientific staff.

STAT+: Color Health moving deeper into cancer services, complete with virtual ‘tumor boards’

The way Color Health’s CEO Othman Laraki sees it, cancer has a scaling problem. New science regularly sets new standards of care, increasing the intricacy of managing an already complex illness. Cancer patients are multiplying faster than oncologists, Laraki said, and costs, too, are exploding. All this makes it difficult for everyone to receive the best possible therapy. The solution that the Silicon Valley executive sees is inevitable.

“In our mind, the only way this is going to be addressed and solved is in a virtual first, AI-driven manner,” Laraki said. “In the coming years, the biggest cancer centers will be virtual first.”

Virtual care for cancer may sound like an oxymoron. After all, the pillars of cancer treatment are almost all hands-on: surgery, radiation, infusions, and the like. But Color Health has been building out a virtual cancer clinic — including a virtual “tumor board” of multidisciplinary experts —  that the company says can deliver and manage care at a high quality. The company just received a certification from the American Society of Clinical Oncology to back it up.

“Failure to Launch” Syndrome: How to Stop Enabling Your Grown Child

When Zeke was in high school, he struggled with anxiety and substance use problems, and he left college after the first semester. Now 25, he is living at home, and his mom Carol is frustrated. While she’s pushed him to go back to school or work, he has only held one part-time job at a local smoothie shop and quit after a few months, embarrassed that high school classmates would see him working there. Another attempt at trade school to become an electrician also didn’t take — it didn’t feel like the right fit. Now he rarely leaves the house, stays up all night playing video games or scrolling online, and sleeps most of the day.

Failure to launch syndrome, highly dependent adult children, boomerang kids — there’s no standard term or definition, but if you’re a parent in this situation you recognize it. You are worried and frustrated about your adult child’s difficulty in leaving the nest, and you don’t know what to do because everything you’ve tried so far hasn’t worked. 

“These aren’t kids who come back home because they finished school, and the first job they get doesn’t pay enough for them to afford rent on an apartment,” says Theresa Welles, the Shapiro Family Director of the Bubrick Center for Pediatric OCD at the Child Mind Institute. “We’re talking about young adults who functionally have hit a wall, so to speak. They’re caught in a loop of dependency.”

What is failure to launch syndrome?

It’s not uncommon for adult children to live with their parents: According to Pew Research Center, 18 percent of adults ages 25 to 34 lived in their parents’ home in 2023, with young men more likely than young women to do so (20 percent vs. 15 percent). Young adults might leave home for a period of time and then move back in with their parents because they can’t find a job. Or for religious or cultural reasons, some adult children expect to live in the family home until they get married. Living at home is not the main criterion for determining a “failure to launch.”

While there is no official clinical definition, researchers who study this group of young adults generally categorize someone as a highly dependent adult child if they are:

  • Not in school, working, or actively looking for work (though physically capable of doing so)
  • Financially dependent on their parents for housing and other necessities
  • Emotionally reliant on parents (i.e., needing constant reassurance that they are okay)  

They usually have very limited social interactions other than online. Often, they have mental health challenges such as anxiety, depression, or OCD, which is a contributing factor, Dr. Welles says.

“They’re at the developmental stage of early adulthood, they’re figuring out who they are,” Dr. Welles says. “The fancy term in psychology is ‘individuation,’ but it’s essentially who you are, both as part of your family and separate from your family.” Highly dependent adult children haven’t made much progress in this stage for several years. Many of them want to change their life path and become more independent, but they struggle with anxiety or fear of failure and don’t follow through on the necessary steps. “Reliance on parents reduces opportunities to build autonomy, which in turn maintains that reliance,” she says. So, they remain stuck.  

Dependent behaviors and parental accommodations

Young adults who are highly dependent often fall into certain patterns of behavior. They don’t do their own laundry, cook, clean, or help out around the house. They rarely leave the home and often shut themselves in their bedroom or live in the basement, avoiding talking to others in person. As a result, they rely on their parents to act as an intermediary with the outside world, such as making doctor’s appointments. They might blame their parents for their difficulties in life.

While parents may not like the situation, they struggle to get their adult child to change. So instead, they accommodate them — especially when they are concerned about their child’s mental health challenges.

“In the world of neurodiversity, accommodations are a good thing — we want accommodations for testing and sensory environments,” says Natalia Aíza, LPC, the author of the forthcoming Anxious to Launch: Parenting Strategies to Help Your Adult Child Move On. “But in the anxious-to-launch world, accommodations are actually interfering with your child becoming independent.”

Aíza gives some examples of unhelpful family accommodations: You make sure there’s food in the fridge, don’t ask them to contribute to paying bills, and may give them spending money. When they get angry or upset, you accept the behavior and feel guilty, thinking you are to blame for the situation. If they are anxious when you aren’t nearby, you don’t travel because it causes them stress. Instead of expecting them to take steps to find a therapist, you do the legwork.

“The number one behavior of the highly dependent adult child is avoidance. I cannot emphasize this enough,” Aíza says. “If your child has a full-on virtual life, that’s their social outlet. They are avoiding real-life challenges. They are avoiding working at jobs that are unpleasant. They are probably avoiding adulting tasks that should fall on them at this point. So, we swoop in and take care of those tasks for them.”

A modern version of an old problem

While adult children have lived with their parents in past generations, researchers argue that phenomenon of highly dependent adult children is on the rise, and young people today seem particularly susceptible. Adolescence is more prolonged now in many cultures, and there’s an emphasis on finding a fulfilling career, not just a job that pays the bills.

Technology contributes to the problem. Playing video games, watching videos, scrolling through social media — “these activities don’t help matters because they can do things that feel like they’re accomplishing something,” Dr. Welles says.  

How to stop enabling your grown child

In Dr. Welles’s practice, she has worked with families where she initially treated the teen for anxiety or OCD, then involved the parents more deeply when the young adult had trouble launching. In one case, the son was in the habit of playing video games late at night and would sleep through class the next day. He had anxiety and depression, and his parents didn’t want to take away video games because it was the one thing he enjoyed doing. But they started turning off the Wi-Fi in the house at a certain time at night.

“It sounds so extreme, like he’s being punished,” Dr. Welles says. “But it’s about saying to him, ‘We’re going to pull back on ways we’ve accommodated that may have unintentionally made your anxiety worse.’” It was important that the parents validated his feelings, saying things like, “You feel like you’re in danger, as if you’re standing in front of a bear, and that’s really hard. But that’s the anxiety lying to you, and it won’t go away if we keep accommodating things that allow you to avoid what you need to do in order to overcome this anxiety.”

And tactics like these made a difference over time. The son is now attending college part-time and working as a server at restaurant. He has a girlfriend and has plans to save enough to move into an apartment with a friend.

Setting boundaries with your adult child

If the adult child doesn’t seem motivated to find a job, Aíza has recommended that parents take them off the family cellphone plan, giving them warning that this will happen by the next month’s bill. “This is not necessarily the most strategic financial choice” because it’s often much cheaper per person on a family plan, she acknowledges. “But it is a perfect first accommodation to remove because it is telling your adult child, ‘This is something you can handle. You can be responsible for it financially and logistically. It is something that I control, and I want to stop controlling parts of your life.’” And it’s often the motivation they need to find a job — something that can earn them $100 for the monthly cell phone bill is small enough that it feels doable.

When families take steps like these, the adult child will likely get angry or upset. “That’s hard. But think about when your kids were toddlers, and they wanted to touch a hot stove,” Dr. Welles says. “They were mad when you said, ‘No, you can’t touch that stove,’ but that didn’t mean you let them do it.”

“The good news is, generally speaking, even if there’s unhappiness in the beginning,” she continues, “pretty quickly, once they start to feel better and are doing the things that they actually care about, it can really help.”

Supporting without enabling adult children

Highly dependent adult children might accuse parents of not being supportive when they pull back on accommodations. Dr. Welles suggests communicating that you hear them and validate their feelings: “You can say things like, ‘Hey, I know this is tough or ‘I know that this makes you really nervous.’ But you combine it with the confidence that they can do it, like ‘I also know you can do it, as hard as it is.’”

Sometimes, you might think you are being supportive when you are actually enabling — like filling out a job application on behalf of the child. “Even if it works and they get an interview, you’re accommodating their anxiety,” Dr. Welles says. “But also, there’s going to be a point when you can’t do something for the child — the interview or the job itself — so the earlier that you can pull back the better.”

If your adult child has both ADHD and anxiety, you can support their executive functioning skills without accommodating the anxiety. “Maybe you sit down with them on Mondays and look at their schedule to help them determine if there’s a way you can help them organize, as opposed to you stepping in and letting them avoid things they need to do because they’re anxious about it,” Dr. Welles says.

Aíza encourages giving the adult child the minimum amount of help needed, to avoid creating another form of dependency. “It’s about noticing, ‘Am I working harder at this than they are?’” she says. “A lot of times the answer is ‘yes,’ and that’s a signal to back off and put more expectations on the child.”

Treatment for highly dependent adult children

While there is no standard treatment for highly dependent adult children, early evidence has shown a form of therapy called SPACE-FTL (Supportive Parenting for Anxious Childhood Emotions – Failure to Launch) to be promising. A variation on an effective treatment for anxiety and OCD, SPACE-FTL involves only the parents, since the adult child is often resistant to seeking help. The program helps parents reduce accommodations step by step and engage extended family and friends to help de-escalate conflict. 

One tactic is to make a plan to deliver a change in accommodation in writing — for instance, explaining that you will stop paying the cellphone bill at the end of the month and why. Doing it in writing (on paper or in a text) makes the message clear and helps you remain calm and non-reactive. If you are expecting an angry or violent response, they can ask a grandparent, uncle, or family friend be in the house when you deliver the letter, since that might make the response less extreme. The relative or friend may even spend the night if the adult child is more likely to cool off when others are present.

Asking for others’ help also helps you stop blaming yourself for the situation. “A lot of parents of highly dependent adults feel shame, but this is not something happening to only one family,” Aíza says. “We need to build on our social supports and get other people on our team so that we don’t feel so isolated in this process. Your adult child may be resisting change, but you don’t have to. It might sound cruel, but our central mandate as parents is making sure our child is okay after we’re gone. We brought them on earth to survive us — that is the design.”

Frequently Asked Questions

What is “failure to launch syndrome”?

“Failure to launch” isn’t a formal diagnosis but describes young adults who are stuck in a pattern of dependence. They’re typically not working or in school, rely on parents financially and emotionally, and struggle to move forward with adult responsibilities.

How can I motivate my adult child to become independent?

Change often starts with parents gradually pulling back on accommodations while staying supportive and calm. Set clear expectations, validate their feelings, and shift responsibility back to them in manageable steps so they can build confidence and autonomy.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Inexpensive seafloor-hopping submersibles could stoke deep-sea science—and mining

Last week, two oblong neon submersibles started to descend nearly 6,000 meters into the Pacific Ocean. Throughout the rest of May, they will map the seafloor in search of critical mineral deposits. 

If all goes well, the vehicles, built by Orpheus Ocean, could help scientists probe the vastly understudied deep sea—and the resources it holds—at a fraction of the cost of existing systems.

But the same submersibles are also attracting deep-sea mining companies, raising concerns about environmental impacts. Find out why they’re drawing so much attention.

The new war room: 10 Things That Matter in AI Right Now 

A new kind of system has entered the war room: conversational AI tools that commanders turn to not just for analysis, but for advice. 

One US defense official told MIT Technology Review that personnel might give these advice engines a list of potential targets to help decide which to strike first. China is commissioning similar tools too.

But as the systems gain traction, they’re also sparking concerns about AI-generated errors, a lack of transparency, and Big Tech gaining undue influence over what information gets seen. 

Here’s how these AI advice engines could impact the battlefield.

How tracking animal movement may save the planet

For decades, wildlife researchers have dreamed of building an “Internet of Animals”—a big-data system that monitors and analyzes animal behavior to help us understand the planet. Advances in sensors, AI, and satellite technology are now bringing that vision to reality.

Scientists want the system to track 100,000 sensor-tagged animals. They believe it could reveal how species respond to climate change and ecosystem loss—and even predict environmental disasters. Read the full story on how their idea could save our planet.
