Once considered a luxury, hiring a nurse, nurse practitioner, or physician assistant is becoming a necessity in many rheumatology practices.

Seeing the wait lists pile up in her Florida practice, Stacy Yonker, MBA, chief executive officer of Sarasota Arthritis Center, knew she had to make some changes. “Everyone’s aging in the boomer generations. Particularly in Florida, we have a lot of people who retire here. In the more southern demographics, it is a very difficult challenge for practices to get new patients in,” she said.

Ms. Yonker is in the process of hiring several nurse practitioners (NPs) to assist in the clinics and infusion suites, lightening the load for the practice’s 11 rheumatologists.

Hiring an advanced practice provider (APP) to support the practice is just a first step. Getting these additional personnel up to speed means an investment in education and fostering good working relationships with NPs, PAs, and the staff’s physicians. Even more importantly, practices need to set realistic expectations on workload for these new hires.

“I tried to hire them, but I couldn’t keep them,” is a statement Christine A. Stamatos, DNP, ANP-C, hears all the time from rheumatologists. Oftentimes it’s because the practice saddles the new hire with 20 patients a day, said Dr. Stamatos, director of the Fibromyalgia Wellness Center within the division of rheumatology at Northwell Health in Huntington, New York. She is also an assistant professor at Hofstra Northwell School of Graduate Nursing and Physician Assistant Studies in Hempstead, New York.

“Twenty patients a day is too much,” Dr. Stamatos said. Overload someone, and they won’t stay. Offer them the support, mentoring, and tools they need to practice in their setting ­­— and they will.
 

Why the Profession Needs APPs

Rheumatology is a much smaller specialty than most, with only a set number of rheumatologists in the field that can provide care to patients. A growing shortage is also looming. Reports from the American College of Rheumatology have projected troubling shortfalls in rheumatologists over the next decade in all regions of the United States.

Many of them aging into retirement “poses a significant issue on being able to continue providing care for the population that experiences the rheumatic disease,” said Ms. Yonker, a director of the National Organization of Rheumatology Management (NORM), a forum that promotes education and advocacy for rheumatology practice managers. People are also living longer, which means more patients are developing arthritis and autoimmune diseases.

Julia M. Swafford, PA-C, a rheumatology physician assistant in Battle Creek, Michigan, sees many advantages of hiring NPs and PAs, and not just from a financial perspective.

Salaries for PAs and NPs aren’t as high and they’re also more accessible than a rheumatologist. “You could train an NP or PA a lot quicker during that same time frame it would take to find a new rheumatology provider,” she offered. And while they may not be as experienced as rheumatologists, “you can kind of mold me on how you like to practice, what medications you may like to use, how you like to treat your patients,” Ms. Swafford said.
 

Hiring Someone With Experience

Recruiting and retaining APPs is not without its challenges.

Finding individuals compatible with this specialty isn’t easy, noted Mark Box, MD, medical director of Carondelet Rheumatology in Kansas City, Missouri. Ideally, APPs should be inquisitive, compassionate, and ready to learn. “Rheumatology is a cognitive specialty where you have to fit many pieces together. You need an APP who wants to embrace that,” he said.

The profession isn’t that “sexy” either, noted Katie Taylor, Carondelet’s practice manager. Patients are often in head-to-toe pain, and miserable. Many have been to other specialists without answers to their questions. For these reasons, rheumatology can be a hard sell for some PAs and NPs.

Nurse practitioners aren’t always comfortable with administering things such as controlled medications, for example. “It’s a hard patient population, and it’s a specialty of exclusion. You’ve got to be really smart to understand our diseases and our processes and our drugs,” Ms. Taylor said. In other words, it’s a difficult environment for an NP to walk into if their previous experience has been limited to upper respiratory issues and urinary tract infections in the primary care setting.

When hiring an APP, rheumatologists should look for someone who demonstrates an interest in lifelong learning, because the field is changing every day. They should exhibit good scores in educational training and have experience working in an emergency department or another field that translates well into rheumatology such as critical care, immunology, hematology, and orthopedics, she said.

Carondelet Rheumatology was specifically looking for an NP with rheumatology experience to support Dr. Box’s solo practice.

He was facing enormous pressure to be in the office every single day of the week. The practice had to cancel patients for its infusion suite on a regular basis when he was out of the office, Ms. Taylor said. “We couldn’t see new patients, and he wasn’t able to touch as many patients as he wanted to. The doctor takes the oath of touching as many in your community as possible, and you’re limited when you’re a one-man show.”

The practice eventually found an NP who already knew how to do joint injections. “We started her with easier diagnoses for things like osteoporosis and gout. She had an orthopedic background, so she was familiar with some of those diseases,” she said.

Even so, she often leaves with questions every day. “It’s a commitment for her to understand and learn so much,” Ms. Taylor said.

New hires will need support from the practice to get comfortable with rheumatology, Dr. Stamatos said. Responsibility should come in gradual steps.

Instead of loading an NP with 20 patients a day, 2 or 3 patients in the first quarter, eventually graduating to 6-8 patients is a more realistic expectation, Dr. Stamatos advised.
 

Shadowing the Physician

Partnerships with physicians is a critical component to this onboarding process.

A nurse practitioner recently hired at Dr. Stamatos’ practice works alongside a physician to manage a panel of 25 patients. “We make sure she gets her training, the resources she needs. I personally meet with her to make sure her education is moving forward, connecting her with radiology, pulmonary, hematology,” and other areas of the practice relevant to her training, she added.

The NP also attends weekly grand rounds and case conferences with the fellows. This is the type of well-rounded support any APP needs, she stressed. “Without proper training, you lose people.”

At Sarasota Arthritis Center, NPs help cover the suites but also get assigned to specific physicians so that they can familiarize themselves with that physician’s panel of patients.

“When we start an APP, they shadow for about twice as long as a new physician would. Usually, they’re shadowing for about 6 weeks, just kind of learning the space. There’s a lot of nurse practitioners or PAs who may not have prior rheumatology experience, so we’re essentially training them from the ground up on rheumatology,” Ms. Yonker said.

Pairing them with one provider often directs what type of disease state they focus on, she continued. This dynamic relationship helps guide decisions on whether to include these NPs in the care of patients with more complex diseases.

At least in her practice, the NPs do not see any new patients. They are simply part of the larger care team. “That’s kind of how we present it to our patients, and it makes them feel more comfortable just because they know that they’re not necessarily being handed off to somebody — that the doctor is still overseeing their care,” Ms. Yonker said.

At the same time, the NPs know that they’re supported, that they too have access to tools and mentorship if they need it, she added.

The new NP at Carondelet Rheumatology piggybacked on the doctor’s schedule for 3 months, slowly taking on infusion patients so she could get familiar with their diseases and respective drugs. Eventually, she got her own schedule and was able to take on new patients.

It’s a team effort, Ms. Taylor noted. The NP does the preliminary workup and then the physician comes in and greets the new patient. Together, they develop a follow-up plan for the patient.
 

Education Resources for Practices

In the case of Dr. Box’s one-physician practice, he was looking for an NP who was willing to be independent and cover things in his absence. “The training has to be there to accomplish that,” said Dr. Box, who likened the training of APPs to a medical residency.

Encouraging them to ask questions, do continuing medical education online and outside reading, are important steps, he added.

In a recent editorial, rheumatologists Eli M. Miloslavsky, MD, and Bethany Marston, MD, offered some strategies for better prepping the APP workforce to meet the demands of rheumatology practices. “Consideration should be given to formal curricula or training programs to help APPs achieve both competence and confidence in treating rheumatologic conditions,” they offered, suggesting an online curriculum developed by the ACR for such a purpose. Fellowship training should also focus on working effectively with APPs, they added.

“Finally, incorporating APPs more effectively into rheumatology professional societies and supporting practices in hiring and training APPs will all be important steps in addressing the rheumatology workforce shortage,” Dr. Miloslavsky and Dr. Marston wrote.

Ms. Yonker said all her APPs take various courses that the ACR and other organizations provide for rheumatology-specific, midlevel positions. “We provide as much training as possible for them to feel comfortable in this space. They are set directly with a physician for a long time and then eventually go into their own space.”

In addition to ACR, the Rheumatology Nurses Society and the Association of Women in Rheumatology offer excellent online training resources for APPs, Ms. Yonker said. “Also, the Bone Health and Osteoporosis Foundation offers an osteoporosis fracture liaison certification which we put APPs through as well,” she added.

Rheumatology practices should also look into an important clinical training grant program from the Rheumatology Research Foundation, Dr. Stamatos advised.

To date, they have “funded almost everyone that applies,” she said. Each grantee receives $25,000 to support training and education involved in onboarding an APP to a rheumatology practice. The money covers attendance at a live rheumatology conference, online educational programs, textbooks, and any society memberships while defraying the cost of training this employee. To increase awareness of the program, the foundation has since expanded the number of available submission dates and the number of grant awardees per year. Currently, the application deadlines for the grants are December 1 and March 1.

For her own health system, Dr. Stamatos has been working on a rheumatology fellowship program for APPs. Through simulation labs, leadership exercises, and other activities, these APPs will learn how to transition from being a new provider to someone who can become part of a practice, she said.

APPs themselves can also get proactive in this learning cycle, Ms. Swafford said. In her view, both APPs and rheumatologists should be conducting didactic lectures and organizing elective rotations with medical students to get them excited about the field. This would establish a good education base that would encourage PAs and NPs to choose rheumatology.

“That’s a huge thing that’s probably missing,” Ms. Swafford said.
 

Buy-in From the Doctor

No recruitment effort is going to work if the rheumatologists in the practice aren’t committed to the model of having an APP, Ms. Yonker said. “Everybody wants to know their purpose in their company and that they’re valued and they’re needed. And so, I think a pitfall would be if your rheumatologist is not sold on the model of expanding the care team. Because this takes work on behalf of the doctor.”

Rheumatologists are very busy, so it’s a hard sell for them to take time out of their busy clinics to train somebody to do a good job taking care of their patients, Ms. Taylor agreed. “I think that we need the physicians that have had success with this and allow them to coach the physicians that are still resistant.”

In his small practice, Dr. Box has encouraged his NP to assist with practice improvements, working with the office manager. These workers are providers and need to be treated as such, he said. “They need to feel like they contribute to the practice more than just grinding through patients.”

Peer support is another successful ingredient for these workers. Ms. Taylor’s NP finds the time to commiserate with her fellow nurse practitioners — other rheumatology nurses who are also learning the ropes. Rheumatologists are smart, and they can be very intimidating, Ms. Taylor said. In their small office, the rheumatologist is her only peer.

“She likes to get out and sort of integrate with other nurse practitioners that are learning too.”
 

When APPs Make a Difference

Practices that take on APPs are reporting positive metrics — mainly, shorter wait times for patients. Ms. Yonker’s physicians have been able to add on one to two new patients a day. Wait times have since dwindled from a 5-month to a 3-month wait with the addition of the NPs. “Three months is still long, but we’re working on getting it to that ideal 6-week wait period, which we’re hoping we can accomplish. So we’re able to get more new patients in for sure,” she said.

Prior to hiring an NP, Ms. Taylor’s practice had to defer acceptances for new patients by at least a year. Now, they’re able to accept about half of all new patient referrals. With the NP on board, “We can get them in within 30 days,” she said.

Sometimes, an APP will go beyond their scope of work to make a difference and better support patients.

Patients with rheumatic and osteopathic conditions are often underdiagnosed in the primary care space. As a result, they are not treated as often as they should be. Seeing a need for specialty care, Ms. Swafford took action.

She currently runs the only bone health clinic in southwest Michigan, coordinating with rheumatologists, NPs, urgent care, hospitalists, and interventional radiologists to attend to these patients more quickly and reduce wait times for care. Specialists will flag things such as nontraumatic hip fractures and vertebral fractures and refer them to Ms. Swafford’s clinic, which is part of Bronson Rheumatology Specialists.

The clinic gets quite a few referrals, and the practice is growing. “Usually, they don’t take as long as a rheumatology referral for a workup, so we can see them a little bit quicker,” usually within 3 weeks, she added.

APPs have an opportunity to make their mark in rheumatology at a time when the profession is experiencing significant gaps in care, Ms. Swafford continued. “Unless we find a way to fill that niche, we’re going to be in a world of trouble in the next 10, 20 years.”

None of the sources reported any disclosures or conflicts of interest.

Once considered a luxury, hiring a nurse, nurse practitioner, or physician assistant is becoming a necessity in many rheumatology practices.

Seeing the wait lists pile up in her Florida practice, Stacy Yonker, MBA, chief executive officer of Sarasota Arthritis Center, knew she had to make some changes. “Everyone’s aging in the boomer generations. Particularly in Florida, we have a lot of people who retire here. In the more southern demographics, it is a very difficult challenge for practices to get new patients in,” she said.

Ms. Yonker is in the process of hiring several nurse practitioners (NPs) to assist in the clinics and infusion suites, lightening the load for the practice’s 11 rheumatologists.

Instead of loading an NP with 20 patients a day, 2 or 3 patients in the first quarter, eventually graduating to 6-8 patients is a more realistic expectation, Dr. Stamatos advised.
 

Shadowing the Physician

Partnerships with physicians is a critical component to this onboarding process.

A nurse practitioner recently hired at Dr. Stamatos’ practice works alongside a physician to manage a panel of 25 patients. “We make sure she gets her training, the resources she needs. I personally meet with her to make sure her education is moving forward, connecting her with radiology, pulmonary, hematology,” and other areas of the practice relevant to her training, she added.

The NP also attends weekly grand rounds and case conferences with the fellows. This is the type of well-rounded support any APP needs, she stressed. “Without proper training, you lose people.”

At Sarasota Arthritis Center, NPs help cover the suites but also get assigned to specific physicians so that they can familiarize themselves with that physician’s panel of patients.

“When we start an APP, they shadow for about twice as long as a new physician would. Usually, they’re shadowing for about 6 weeks, just kind of learning the space. There’s a lot of nurse practitioners or PAs who may not have prior rheumatology experience, so we’re essentially training them from the ground up on rheumatology,” Ms. Yonker said.

Pairing them with one provider often directs what type of disease state they focus on, she continued. This dynamic relationship helps guide decisions on whether to include these NPs in the care of patients with more complex diseases.

At least in her practice, the NPs do not see any new patients. They are simply part of the larger care team. “That’s kind of how we present it to our patients, and it makes them feel more comfortable just because they know that they’re not necessarily being handed off to somebody — that the doctor is still overseeing their care,” Ms. Yonker said.

At the same time, the NPs know that they’re supported, that they too have access to tools and mentorship if they need it, she added.

The new NP at Carondelet Rheumatology piggybacked on the doctor’s schedule for 3 months, slowly taking on infusion patients so she could get familiar with their diseases and respective drugs. Eventually, she got her own schedule and was able to take on new patients.

It’s a team effort, Ms. Taylor noted. The NP does the preliminary workup and then the physician comes in and greets the new patient. Together, they develop a follow-up plan for the patient.
 

Education Resources for Practices

In the case of Dr. Box’s one-physician practice, he was looking for an NP who was willing to be independent and cover things in his absence. “The training has to be there to accomplish that,” said Dr. Box, who likened the training of APPs to a medical residency.

Encouraging them to ask questions, do continuing medical education online and outside reading, are important steps, he added.

In a recent editorial, rheumatologists Eli M. Miloslavsky, MD, and Bethany Marston, MD, offered some strategies for better prepping the APP workforce to meet the demands of rheumatology practices. “Consideration should be given to formal curricula or training programs to help APPs achieve both competence and confidence in treating rheumatologic conditions,” they offered, suggesting an online curriculum developed by the ACR for such a purpose. Fellowship training should also focus on working effectively with APPs, they added.

“Finally, incorporating APPs more effectively into rheumatology professional societies and supporting practices in hiring and training APPs will all be important steps in addressing the rheumatology workforce shortage,” Dr. Miloslavsky and Dr. Marston wrote.

Ms. Yonker said all her APPs take various courses that the ACR and other organizations provide for rheumatology-specific, midlevel positions. “We provide as much training as possible for them to feel comfortable in this space. They are set directly with a physician for a long time and then eventually go into their own space.”

In addition to ACR, the Rheumatology Nurses Society and the Association of Women in Rheumatology offer excellent online training resources for APPs, Ms. Yonker said. “Also, the Bone Health and Osteoporosis Foundation offers an osteoporosis fracture liaison certification which we put APPs through as well,” she added.

Rheumatology practices should also look into an important clinical training grant program from the Rheumatology Research Foundation, Dr. Stamatos advised.

To date, they have “funded almost everyone that applies,” she said. Each grantee receives $25,000 to support training and education involved in onboarding an APP to a rheumatology practice. The money covers attendance at a live rheumatology conference, online educational programs, textbooks, and any society memberships while defraying the cost of training this employee. To increase awareness of the program, the foundation has since expanded the number of available submission dates and the number of grant awardees per year. Currently, the application deadlines for the grants are December 1 and March 1.

For her own health system, Dr. Stamatos has been working on a rheumatology fellowship program for APPs. Through simulation labs, leadership exercises, and other activities, these APPs will learn how to transition from being a new provider to someone who can become part of a practice, she said.

APPs themselves can also get proactive in this learning cycle, Ms. Swafford said. In her view, both APPs and rheumatologists should be conducting didactic lectures and organizing elective rotations with medical students to get them excited about the field. This would establish a good education base that would encourage PAs and NPs to choose rheumatology.

“That’s a huge thing that’s probably missing,” Ms. Swafford said.
 

Buy-in From the Doctor

No recruitment effort is going to work if the rheumatologists in the practice aren’t committed to the model of having an APP, Ms. Yonker said. “Everybody wants to know their purpose in their company and that they’re valued and they’re needed. And so, I think a pitfall would be if your rheumatologist is not sold on the model of expanding the care team. Because this takes work on behalf of the doctor.”

Rheumatologists are very busy, so it’s a hard sell for them to take time out of their busy clinics to train somebody to do a good job taking care of their patients, Ms. Taylor agreed. “I think that we need the physicians that have had success with this and allow them to coach the physicians that are still resistant.”

In his small practice, Dr. Box has encouraged his NP to assist with practice improvements, working with the office manager. These workers are providers and need to be treated as such, he said. “They need to feel like they contribute to the practice more than just grinding through patients.”

Peer support is another successful ingredient for these workers. Ms. Taylor’s NP finds the time to commiserate with her fellow nurse practitioners — other rheumatology nurses who are also learning the ropes. Rheumatologists are smart, and they can be very intimidating, Ms. Taylor said. In their small office, the rheumatologist is her only peer.

“She likes to get out and sort of integrate with other nurse practitioners that are learning too.”
 

When APPs Make a Difference

Practices that take on APPs are reporting positive metrics — mainly, shorter wait times for patients. Ms. Yonker’s physicians have been able to add on one to two new patients a day. Wait times have since dwindled from a 5-month to a 3-month wait with the addition of the NPs. “Three months is still long, but we’re working on getting it to that ideal 6-week wait period, which we’re hoping we can accomplish. So we’re able to get more new patients in for sure,” she said.

Prior to hiring an NP, Ms. Taylor’s practice had to defer acceptances for new patients by at least a year. Now, they’re able to accept about half of all new patient referrals. With the NP on board, “We can get them in within 30 days,” she said.

Sometimes, an APP will go beyond their scope of work to make a difference and better support patients.

Patients with rheumatic and osteopathic conditions are often underdiagnosed in the primary care space. As a result, they are not treated as often as they should be. Seeing a need for specialty care, Ms. Swafford took action.

She currently runs the only bone health clinic in southwest Michigan, coordinating with rheumatologists, NPs, urgent care, hospitalists, and interventional radiologists to attend to these patients more quickly and reduce wait times for care. Specialists will flag things such as nontraumatic hip fractures and vertebral fractures and refer them to Ms. Swafford’s clinic, which is part of Bronson Rheumatology Specialists.

The clinic gets quite a few referrals, and the practice is growing. “Usually, they don’t take as long as a rheumatology referral for a workup, so we can see them a little bit quicker,” usually within 3 weeks, she added.

APPs have an opportunity to make their mark in rheumatology at a time when the profession is experiencing significant gaps in care, Ms. Swafford continued. “Unless we find a way to fill that niche, we’re going to be in a world of trouble in the next 10, 20 years.”

None of the sources reported any disclosures or conflicts of interest.

Radiation oncologists from the largest professional societies have come together to lobby for Medicare payment reform.

The American Society for Radiation Oncology (ASTRO) recently announced its partnership with three other groups — the American College of Radiation Oncology, the American College of Radiology, and the American Society of Clinical Oncology — to change how the specialty is paid for services. 

Over the past decade, radiation oncologists have seen a 23% drop in Medicare reimbursement for radiation therapy services, with more cuts to come, according to a press release from ASTRO.

Traditionally, Medicare has reimbursed on the basis of the fraction of radiation delivered. But with moves toward hypofractionated regimens, deescalated therapy, and other changes in the field, reimbursement has continued to dwindle. 

The cuts have led to practice consolidation and closures that threaten patient access especially in rural and underserved areas, a spokesperson for the group told this news organization.

To reverse this trend, ASTRO recently proposed the Radiation Oncology Case Rate program, a legislative initiative to base reimbursements on patient volumes instead of fractions delivered. 

ASTRO is currently drafting a congressional bill to change the current payment structure, which “has become untenable,” the spokesperson said.

For years, oncologist John DiPersio, MD, PhD, had faced frustrating encounters with insurers that only cover medications through a process called white bagging.

Instead of the traditional buy-and-bill pathway where oncologists purchase specialty drugs, such as infusion medications, directly from the distributor or manufacturer, white bagging requires physicians to receive these drugs from a specialty pharmacy.

On its face, the differences may seem minor. However, as Dr. DiPersio knows well, the consequences for oncologists and patients are not.

White bagging, research showed, leads to higher costs for patients and lower reimbursement for oncology practices. The practice can also create safety issues for patients.

That is why Dr. DiPersio’s cancer center does not allow white bagging.

And when insurers refuse to reconsider the white bagging policy, his cancer team is left with few options.

“Sometimes, we have to redirect patients to other places,” said Dr. DiPersio, a bone marrow transplant specialist at Siteman Cancer Center, Washington University, St. Louis.

In emergency instances where patients cannot wait, Dr. DiPersio’s team will administer their own stock of a drug. In such cases, “we accept the fact that by not allowing white bagging, there may be nonpayment. We take the hit as far as cost.”

Increasingly, white bagging mandates are becoming harder for practices to avoid.

In a 2021 survey, 87% of Association of Community Cancer Centers members said white bagging has become an insurer mandate for some of their patients.

A 2023 analysis from Adam J. Fein, PhD, of Drug Channels Institute, Philadelphia, found that white bagging accounted for 17% of infused oncology product sourcing from clinics and 38% from hospital outpatient departments, up from 15% to 28% in 2019. Another practice called brown bagging, where specialty pharmacies send drugs directly to patients, creates many of the same issues but is much less prevalent than white bagging.

This change reflects “the broader battle over oncology margins” and insurers’ “attempts to shift costs to providers, patients, and manufacturers,” Dr. Fein wrote in his 2023 report.
 

White Bagging: Who Benefits?

At its core, white bagging changes how drugs are covered and reimbursed. Under buy and bill, drugs fall under a patient’s medical benefit. Oncologists purchase drugs directly from the manufacturer or distributor and receive reimbursement from the insurance company for both the cost of the drug as well as for administering it to patients.

Under white bagging, drugs fall under a patient’s pharmacy benefit. In these instances, a specialty pharmacy prepares the infusion ahead of time and ships it directly to the physician’s office or clinic. Because oncologists do not purchase the drug directly, they cannot bill insurers for it; instead, the pharmacy receives reimbursement for the drug and the provider is reimbursed for administering it.

Insurance companies argue that white bagging reduces patients’ out-of-pocket costs “by preventing hospitals and physicians from charging exorbitant fees to buy and store specialty medicines themselves,” according to advocacy group America’s Health Insurance Plans (AHIP).

Data from AHIP suggested that hospitals mark up the price of cancer drugs considerably, charging about twice as much as a specialty pharmacy, and that physician’s offices also charge about 23% more. However, these figures highlight how much insurers are billed, not necessarily how much patients ultimately pay.

Other evidence shows that white bagging raises costs for patients while reducing reimbursement for oncologists and saving insurance companies money.

A recent analysis in JAMA Network Open, which looked at 50 cancer drugs associated with the highest total spending from the 2020 Medicare Part B, found that mean insurance payments to providers were more than $2000 lower for drugs distributed under bagging than traditional buy and bill: $7405 vs $9547 per patient per month. Investigators found the same pattern in median insurance payments: $5746 vs $6681. Patients also paid more out-of-pocket each month with bagging vs buy and bill: $315 vs $145.

For patients with private insurance, “out-of-pocket costs were higher under bagging practice than the traditional buy-and-bill practice,” said lead author Ya-Chen Tina Shih, PhD, a professor in the department of radiation oncology at UCLA Health, Los Angeles.

White bagging is entirely for the profit of health insurers, specialty pharmacies, and pharmacy benefit managers, the middlemen who negotiate drug prices on behalf of payers.

Many people may not realize the underlying money-making strategies behind white bagging, explained Ted Okon, executive director for Community Oncology Alliance, which opposes the practice. Often, an insurer, pharmacy benefit manager, and mail order pharmacy involved in the process are all affiliated with the same corporation. In such cases, an insurer has a financial motive to control the source of medications and steer business to its affiliated pharmacies, Mr. Okon said.

When a single corporation owns numerous parts of the drug supply chain, insurers end up having “sway over what drug to use and then how the patient is going to get it,” Mr. Okon said. If the specialty pharmacy is a 340B contract pharmacy, it likely also receives a sizable discount on the drug and can make more money through white bagging.
 

Dangerous to Patients?

On the safety front, proponents of white bagging say the process is safe and efficient.

Specialty pharmacies are used only for prescription drugs that can be safely delivered, said AHIP spokesman David Allen.

In addition to having the same supply chain safety requirements as any other dispensing pharmacy, “specialty pharmacies also must meet additional safety requirements for specialty drugs” to ensure “the safe storage, handling, and dispensing of the drugs,” Mr. Allen explained.

However, oncologists argue that white bagging can be dangerous.

With white bagging, specialty pharmacies send a specified dose to practices, which does not allow practices to source and mix the drug themselves or make essential last-minute dose-related changes — something that happens every day in the clinic, said Debra Patt, MD, PhD, MBA, executive vice president for policy and strategy for Texas Oncology, Dallas.

White bagging also increases the risk for drug contamination, results in drug waste if the medication can’t be used, and can create delays in care.

Essentially, white bagging takes control away from oncologists and makes patient care more unpredictable and complex, explained Dr. Patt, president of the Texas Society of Clinical Oncology, Rockville, Maryland.

Dr. Patt, who does not allow white bagging in her practice, recalled a recent patient with metastatic breast cancer who came to the clinic for trastuzumab deruxtecan. The patient had been experiencing acute abdominal pain. After an exam and CT, Dr. Patt found the breast cancer had grown and moved into the patient’s liver.

“I had to discontinue that plan and change to a different chemotherapy,” she said. “If we had white bagged, that would have been a waste of several thousand dollars. Also, the patient would have to wait for the new medication to be white bagged, a delay that would be at least a week and the patient would have to come back at another time.”

When asked about the safety concerns associated with white bagging, Lemrey “Al” Carter, MS, PharmD, RPh, executive director of the National Association of Boards of Pharmacy (NABP), said the NABP “acknowledges that all these issues exist.

“It is unfortunate if patient care or costs are negatively impacted,” Dr. Carter said, adding that “boards of pharmacy can investigate if they are made aware of safety concerns at the pharmacy level. If a violation of the pharmacy laws or rules is found, boards can take action.”
 

More Legislation to Prevent Bagging

As white bagging mandates from insurance companies ramp up, more practices and states are banning it.

In the Association of Community Cancer Centers’ 2021 survey, 59% of members said their cancer program or practice does not allow white bagging.

At least 15 states have introduced legislation that restricts and/or prohibits white and brown bagging practices, according to a 2023 report by the Institute for Clinical and Economic Review. Some of the proposed laws would restrict mandates by stipulating that physicians are reimbursed at the contracted amount for clinician-administered drugs, whether obtained from a pharmacy or the manufacturer.

Louisiana, Vermont, and Minnesota were the first to enact anti–white bagging laws. Louisiana’s law, for example, enacted in 2021, bans white bagging and requires insurers to reimburse providers for physician-administered drugs if obtained from out-of-network pharmacies.

When the legislation passed, white bagging was just starting to enter the healthcare market in Louisiana, and the state wanted to act proactively, said Kathy W. Oubre, MS, CEO of the Pontchartrain Cancer Center, Covington, Louisiana, and president of the Coalition of Hematology and Oncology Practices, Mountain View, California.

“We recognized the growing concern around it,” Ms. Oubre said. The state legislature at the time included physicians and pharmacists who “really understood from a practice and patient perspective, the harm that policy could do.”

Ms. Oubre would like to see more legislation in other states and believes Louisiana’s law is a good model.

At the federal level, the American Hospital Association and American Society of Health-System Pharmacists have also urged the US Food and Drug Administration to take appropriate enforcement action to protect patients from white bagging.

Legislation that bars white bagging mandates is the most reasonable way to support timely and appropriate access to cancer care, Dr. Patt said. In the absence of such legislation, she said oncologists can only opt out of insurance contracts that may require the practice.

“That is a difficult position to put oncologists in,” she said.

Other evidence shows that white bagging raises costs for patients while reducing reimbursement for oncologists and saving insurance companies money.

A recent analysis in JAMA Network Open, which looked at 50 cancer drugs associated with the highest total spending from the 2020 Medicare Part B, found that mean insurance payments to providers were more than $2000 lower for drugs distributed under bagging than traditional buy and bill: $7405 vs $9547 per patient per month. Investigators found the same pattern in median insurance payments: $5746 vs $6681. Patients also paid more out-of-pocket each month with bagging vs buy and bill: $315 vs $145.

For patients with private insurance, “out-of-pocket costs were higher under bagging practice than the traditional buy-and-bill practice,” said lead author Ya-Chen Tina Shih, PhD, a professor in the department of radiation oncology at UCLA Health, Los Angeles.

White bagging is entirely for the profit of health insurers, specialty pharmacies, and pharmacy benefit managers, the middlemen who negotiate drug prices on behalf of payers.

Many people may not realize the underlying money-making strategies behind white bagging, explained Ted Okon, executive director for Community Oncology Alliance, which opposes the practice. Often, an insurer, pharmacy benefit manager, and mail order pharmacy involved in the process are all affiliated with the same corporation. In such cases, an insurer has a financial motive to control the source of medications and steer business to its affiliated pharmacies, Mr. Okon said.

When a single corporation owns numerous parts of the drug supply chain, insurers end up having “sway over what drug to use and then how the patient is going to get it,” Mr. Okon said. If the specialty pharmacy is a 340B contract pharmacy, it likely also receives a sizable discount on the drug and can make more money through white bagging.
 

Dangerous to Patients?

On the safety front, proponents of white bagging say the process is safe and efficient.

Specialty pharmacies are used only for prescription drugs that can be safely delivered, said AHIP spokesman David Allen.

In addition to having the same supply chain safety requirements as any other dispensing pharmacy, “specialty pharmacies also must meet additional safety requirements for specialty drugs” to ensure “the safe storage, handling, and dispensing of the drugs,” Mr. Allen explained.

However, oncologists argue that white bagging can be dangerous.

With white bagging, specialty pharmacies send a specified dose to practices, which does not allow practices to source and mix the drug themselves or make essential last-minute dose-related changes — something that happens every day in the clinic, said Debra Patt, MD, PhD, MBA, executive vice president for policy and strategy for Texas Oncology, Dallas.

White bagging also increases the risk for drug contamination, results in drug waste if the medication can’t be used, and can create delays in care.

Essentially, white bagging takes control away from oncologists and makes patient care more unpredictable and complex, explained Dr. Patt, president of the Texas Society of Clinical Oncology, Rockville, Maryland.

Dr. Patt, who does not allow white bagging in her practice, recalled a recent patient with metastatic breast cancer who came to the clinic for trastuzumab deruxtecan. The patient had been experiencing acute abdominal pain. After an exam and CT, Dr. Patt found the breast cancer had grown and moved into the patient’s liver.

“I had to discontinue that plan and change to a different chemotherapy,” she said. “If we had white bagged, that would have been a waste of several thousand dollars. Also, the patient would have to wait for the new medication to be white bagged, a delay that would be at least a week and the patient would have to come back at another time.”

When asked about the safety concerns associated with white bagging, Lemrey “Al” Carter, MS, PharmD, RPh, executive director of the National Association of Boards of Pharmacy (NABP), said the NABP “acknowledges that all these issues exist.

“It is unfortunate if patient care or costs are negatively impacted,” Dr. Carter said, adding that “boards of pharmacy can investigate if they are made aware of safety concerns at the pharmacy level. If a violation of the pharmacy laws or rules is found, boards can take action.”
 

More Legislation to Prevent Bagging

As white bagging mandates from insurance companies ramp up, more practices and states are banning it.

In the Association of Community Cancer Centers’ 2021 survey, 59% of members said their cancer program or practice does not allow white bagging.

At least 15 states have introduced legislation that restricts and/or prohibits white and brown bagging practices, according to a 2023 report by the Institute for Clinical and Economic Review. Some of the proposed laws would restrict mandates by stipulating that physicians are reimbursed at the contracted amount for clinician-administered drugs, whether obtained from a pharmacy or the manufacturer.

Louisiana, Vermont, and Minnesota were the first to enact anti–white bagging laws. Louisiana’s law, for example, enacted in 2021, bans white bagging and requires insurers to reimburse providers for physician-administered drugs if obtained from out-of-network pharmacies.

When the legislation passed, white bagging was just starting to enter the healthcare market in Louisiana, and the state wanted to act proactively, said Kathy W. Oubre, MS, CEO of the Pontchartrain Cancer Center, Covington, Louisiana, and president of the Coalition of Hematology and Oncology Practices, Mountain View, California.

“We recognized the growing concern around it,” Ms. Oubre said. The state legislature at the time included physicians and pharmacists who “really understood from a practice and patient perspective, the harm that policy could do.”

Ms. Oubre would like to see more legislation in other states and believes Louisiana’s law is a good model.

At the federal level, the American Hospital Association and American Society of Health-System Pharmacists have also urged the US Food and Drug Administration to take appropriate enforcement action to protect patients from white bagging.

Legislation that bars white bagging mandates is the most reasonable way to support timely and appropriate access to cancer care, Dr. Patt said. In the absence of such legislation, she said oncologists can only opt out of insurance contracts that may require the practice.

“That is a difficult position to put oncologists in,” she said.

France did it 5 years ago and now, from January 1, the Dutch have followed suit, banning devices such as mobile phones and tablets in classrooms unless needed during lessons, for medical reasons, or by students with disabilities. The ban aims to limit distractions during the school day. 

We could all surely do with some device detox, but the question remains whether too much screen time has an impact on child development. Karen Mansfield, PhD, a postdoctoral researcher on adolescent well-being in the digital age at Oxford University, told this news organization, “The evidence is definitely not set in stone. There have been some recent reviews of screen time effects on children, demonstrating very mixed findings.”

The latest research, said Dr. Mansfield, is still young, lacking consistency in findings, and rife with misinterpretation.

Tiziana Metitieri, a cognitive neuropsychologist at the Meyer Hospital in Florence, Italy, echoed these sentiments, suggesting that the sheer quantity of screen time is an insufficient metric for understanding its impact on cognitive and psychological development. “There are two main reasons for this,” she explained to this news organization. “Firstly, because the current measurements of screen time rely on self-report data, which can be affected by an overestimation or underestimation of objective usage due to social desirability bias. Secondly, because digital experiences differ in terms of content, device used, context, location, and individuals involved.”
 

Are Politicians in Too Much of a Rush?

UNESCO’s most recent report on technology in education highlighted a correlation between excessive mobile phone use and reduced educational performance and emotional stability.

The OECD report “Empowering Young Children in the Digital Age,” rightly suggested there is a need to improve protection in digital environments, bridge the digital divide, and educate parents and teachers on safe digital practices.

But Dr. Mansfield said, “Currently, policy implementation is racing far ahead of the evidence, with similar suggestions to ban smartphones in schools in the United Kingdom and Canada. However, there is no available evidence on the long-term benefits of banning smartphones. Much of the research behind the OECD and UNESCO policies is observational in nature, which limits causal interpretation more than with interventions.”

While most governments are not pursuing restrictive practices, Dr. Metitieri said that “their approaches are based on their political ideology, often using moral panic as a means to rally support, showing their heartfelt commitment to defending against the invasions of digital technology ruining human civilizations.” 

Sakshi Ghai, PhD, Dr. Mansfield’s fellow postdoctoral researcher at Oxford University, reiterated Dr. Metitieri’s concerns, “Screen time as a concept has limitations, and policy guidance needs to be careful when drawing insights from such limited evidence. What do we mean by screen time? How can time spent on different activities be clearly delineated? An oversimplistic focus on screen time may overlook the nuances and complexity of digital media use.”
 

The Key Is the What and Where

Digital screens can be productive for children, such as when used for educational purposes, be it to join a class over Zoom or partake in extracurricular educational activities. However, Dr. Ghai emphasized the importance of identifying what constitutes reasonable consumption of digital media. “Screens can help disadvantaged children achieve positive educational outcomes, particularly those with learning difficulties,” said Dr. Ghai. “Using media to interact with other children can also bring positive social connections to racially diverse children or those from the LGBTQ community, which reiterates why finding the balance that allows children to reap the benefits of digital technology while safeguarding their mental, physical, and social health, is crucial.”

On the other hand, Dr. Metitieri explained that there is evidence that passive exposure to educational content does not necessarily lead to growth benefits. “The key is the relational environment in which these digital experiences occur,” she said. 

Dr. Mansfield said a lot of research describes excessive use of digital media as a form of addiction. “Some studies have attempted to validate and test ‘smartphone addiction’ scales for adolescent. Besides pathologizing an increasingly common activity, such self-report scales are highly subjective, implying serious limitations when attempting to define ‘cut offs’ or diagnostic thresholds.”

Previous efforts to determine benchmarks for screen time usage, focusing on the relationship between historical screen usage and present mental well-being, have overlooked the nature of the digital interaction and the social and technological backdrop. “Effects of screen time on children is a continuously changing, rapidly developing research field, and other contextual factors have been shown to play a greater role on mental health,” explained Dr. Mansfield.
 

Are School Bans Too Restrictive?

Implementing nationwide policies that warrant a dramatic shift in how we approach activities that have become second nature, such as using a mobile phone, is profoundly difficult, particularly as evidence is inconclusive and inconsistent. “The long-term effects of different types of digital content on children’s learning are yet to be clear, and most education-related research so far has been carried out with college students,” said Dr. Mansfield.

For concerned parents and schools, Dr. Metitieri advised against overly restrictive approaches. “Children and adolescents can find ways around restrictions at home and school, meaning that an overly restrictive approach is limited in its effectiveness,” she said. “The best way to adapt to the changes happening in education, relationships, work, and leisure is through a combination of experiences offline and digital education.”

Mirroring Dr. Metitieri’s outlook, Dr. Mansfield suggested, “Restricting the use of smartphones and other personal devices is one method to reduce distraction, but ultimately, children will need to learn to optimize their use of digital devices.”

Recent Dutch media reports cited government ministers’ consultations with neuropsychiatrist Theo Compernolle, MD, PhD, who compared children’s current smartphone usage patterns to addiction and suggested that such habits may hinder the development of the prefrontal cortex. However, Dr. Mansfield said, “There is no evidence to back up this claim.” Although she acknowledged the potential short-term benefits of a screen time ban in enhancing classroom concentration, she said, “One study directly tested this hypothesis and found no association between social media use and brain development, meaning that any claims of long-term effects remain purely speculative.”

The issue of children’s screen time is complex. Understanding the content and context of screen time, educating parents and teachers, and integrating digital experiences with offline activities seem to be the way forward. While governments contend with the complexities of managing this rather modern challenge, the balance between digital engagement and cognitive development remains a critical topic for continued research and thoughtful policymaking. Dr. Metitieri summed it up, “As adult members of the digital society, it is important for us to educate ourselves on how to effectively use online platforms before sharing our experiences and concerns about the online world with children and adolescents.”

Intake of protein, especially from plants, in middle age is associated with higher odds of healthy aging and positive mental and physical health status in older women, a recent analysis of the Nurses’ Health Study (NHS) data suggests.

The study is said to be the first to examine the long-term impact of midlife protein consumption on later health status.

Writing in the American Journal of Clinical Nutrition, a team led by Andres V. Ardisson Korat, DSc, a nutritional epidemiologist at the USDA Human Nutrition Research Center on Aging at Tufts University in Boston, Massachusetts, found the following midlife protein–related odds ratios (ORs) for later healthy aging measured at ages 70-93.

For each 3% energy increment from various protein sources:

• 1.05 (95% confidence interval, 1.01-1.10) for total protein
• 1.07 (1.02-1.11) for animal protein
• 1.14 (1.06-1.23) for dairy protein
• 1.38 (1.24-1.54) for plant protein 

In substitution analyses, significant positive associations were observed for the isocaloric replacement of animal or dairy protein, carbohydrate, or fat with plant protein — with increased ORs for healthy aging of 1.22-1.58 for each 3% of energy replacement.

On the measure of physical function, for example, replacing calories from all macronutrient variables with equivalent calories from plant protein was associated with 20%-60% higher odds of having no physical function limitations. Plant protein was also associated with higher odds for good mental status.

“Other studies have looked at protein intake in older adults, but we felt midlife was a more relevant etiological window,” Dr. Ardisson Korat said in an interview. “Our findings generally align, however, with those of protein intake in older populations, which have shown that protein can reduce the risk of frailty.”

He added that the benefits of protein, especially from plant sources, would likely apply to men as well and increasing plant protein intake is not difficult. “If you want a snack during the day, eat a handful of nuts instead of potato chips,” he advised. And eating several meals a week featuring beans, peas, lentils, tofu, whole grains, or seeds is an easy way to boost dietary plant protein, which comes with health-promoting soluble and insoluble fiber as well as antioxidant and anti-inflammatory polyphenols and other phytochemicals.

Conversely, plant but not animal protein consumption in older adulthood was linked to a lower risk of frailty in a previous NHS trial.

Higher plant protein intake was associated with a better probability of achieving healthy aging defined by changes in functional impairments, self-reported health/vitality, mental health, and use of health services in the Spanish Seniors-Estudio Sobre Nutricion y Riesgo Cardiovascular.

In contrast, animal protein intake in middle adulthood has been linked to an increased risk of premature death from chronic diseases driven by cardiovascular disease mortality.

The present findings are consistent with those observed for protein intakes in older adulthood, Dr. Ardisson Korat said.

“This study underscores the health advantages for midlife adults consuming adequate dietary protein — particularly plant protein — as one component of pursuing a healthy lifestyle,” said Douglas R. Dirschl, MD, chair of orthopedic surgery at Baylor College of Medicine in Houston, Texas. Most Americans consume adequate amounts of protein, but according to Dr. Dirschl, who treats many older patients for osteoporotic fractures and other musculoskeletal conditions, many US diets are subpar in this nutrient.

While protein is essential for bone and muscle formation and maintenance, “a surprising number of Americans are protein deficient, even those who seem hale and are overweight,” he said.


 

Dietary Recommendations for Midlife Patients

Physicians should therefore advise midlife patients to meet or perhaps modestly exceed the recommended dietary allowance (RDA) for protein of 0.8 g/kg per day and to make plant protein a substantial component of daily dietary protein intake, Dr. Dirschl said.

Luke D. Kim, MD, MEd, a geriatrician at the Cleveland Clinic in Cleveland, Ohio, noted that patients with lower socioeconomic status or with difficulty in day-to-day functioning are likely to have suboptimal protein intake. Such patients may need encouragement to eat more protein. “But we should keep in mind that showing a higher associated odds ratio of better health with increased protein take does not mean causality,” he said.

According to Rachel L. Amdur, MD, an internist at Northwestern Medicine in Chicago, Illinois, the long-term follow-up data from the NHS are uniquely helpful. “Middle-aged persons may think they no longer need much dietary protein and need to be reminded. Sometimes eating carbohydrates is just easier,” she said in an interview. Physicians need to asses and counsel patients on nutrition at all stages of life. “As I tell my patients, it’s best to think of your future self now.”

In agreement is Louis J. Morledge, MD, an internist at Northwell Health in New York City. “I firmly counsel my patients about adequate and often increased protein intake in middle life. But this is always within a larger framework of overall nutritional health.” He added that middle-aged persons often find themselves “stuck in food ruts,” and one of his clinical focuses is to advise patients about the importance of healthier food choices so they can better adjust to mental, emotional, physical, and skeletal changes as they age.
 

Study Details

The NHS analysis drew on prospective data from 48,762 nurses under age 60 in 1984. Total protein, animal protein, dairy protein, and plant protein were derived from validated food-frequency questionnaires.

Adjusting for lifestyle, demographics, and health status, the investigators identified 3721 (7.6% of cohort) eligible participants. The mean age of participants at baseline was 48.6 years; 38.6% had body mass indexes (BMI; in kg/m²) greater than 25; 22.9% were current smokers; and 88.2% were married.

Healthy aging was defined as freedom from 11 major chronic diseases, good mental health, and no impairments in cognitive or physical function, as assessed in the 2014 or 2016 NHS participant questionnaires. Diseases/treatments included cancer, type 2 diabetes, myocardial infarction, coronary artery bypass graft or coronary angioplasty, congestive heart failure, stroke, kidney failure, chronic obstructive pulmonary disease, Parkinson disease, multiple sclerosis, and amyotrophic lateral sclerosis.

Mean total protein consumption as a percentage of energy was 18.3% (standard deviation 3%), slightly higher than the average 16% in the US diet. Of this, 13.3% derived from animals, 3.6% from dairy products, and 4.9% from plants.

Total protein intake was positively associated with higher education levels, being physically active, higher BMI, and a baseline history of hypertension and hypercholesterolemia. Conversely, total protein intake was inversely associated with intakes of total carbohydrates, nuts, alcohol, and sugar-sweetened beverages.

The associations between protein intake and healthy aging are complex and not fully understood, the authors stated.
 

Effects of Protein Intake

In studies of older adult populations lower protein intake has been associated with lean mass loss. Animal protein supplementation studies in older adults have shown lean mass gains potentially related to amino acid composition.

In terms of mechanisms, evidence suggests that protein-related activation of the rapamycin complex 1 pathway may play a role, the authors suggested. The activity of this signaling pathway decreases with age.

Rapamycin, a compound used to prevent organ transplant rejection, has been associated with delayed aging. In the body, dietary protein and exercise activate this pathway, thereby stimulating muscle protein synthesis and possibly improving physical function.

As for the differential associations of plant and animal protein on the chronic disease domain of the healthy aging phenotype, Dr. Ardisson Korat and coauthors said plant protein has been associated with favorable levels of important risk factors for cardiometabolic diseases, such as reduced LDL cholesterol, lower blood pressure, and insulin sensitivity, as well as decreased levels of proinflammatory markers.

Conversely, total and animal protein intakes have been positively associated with concentrations of insulin-like growth factor 1, which is implicated in the growth of malignant cells in breast and prostate tissue.

This study is the first step in evaluating the long-term health effect of protein intake in midlife, the relevant development window for most chronic conditions, the NHS study authors said. More research is needed, however, to corroborate the study findings in other populations and identify underlying mechanisms.

This study was supported by the USDA Agricultural Research Service and the National Institutes of Health. The authors reported no conflicts of interest. The commentators disclosed no relevant competing interests.

In substitution analyses, significant positive associations were observed for the isocaloric replacement of animal or dairy protein, carbohydrate, or fat with plant protein — with increased ORs for healthy aging of 1.22-1.58 for each 3% of energy replacement.

On the measure of physical function, for example, replacing calories from all macronutrient variables with equivalent calories from plant protein was associated with 20%-60% higher odds of having no physical function limitations. Plant protein was also associated with higher odds for good mental status.

“Other studies have looked at protein intake in older adults, but we felt midlife was a more relevant etiological window,” Dr. Ardisson Korat said in an interview. “Our findings generally align, however, with those of protein intake in older populations, which have shown that protein can reduce the risk of frailty.”

He added that the benefits of protein, especially from plant sources, would likely apply to men as well and increasing plant protein intake is not difficult. “If you want a snack during the day, eat a handful of nuts instead of potato chips,” he advised. And eating several meals a week featuring beans, peas, lentils, tofu, whole grains, or seeds is an easy way to boost dietary plant protein, which comes with health-promoting soluble and insoluble fiber as well as antioxidant and anti-inflammatory polyphenols and other phytochemicals.

Conversely, plant but not animal protein consumption in older adulthood was linked to a lower risk of frailty in a previous NHS trial.

Higher plant protein intake was associated with a better probability of achieving healthy aging defined by changes in functional impairments, self-reported health/vitality, mental health, and use of health services in the Spanish Seniors-Estudio Sobre Nutricion y Riesgo Cardiovascular.

In contrast, animal protein intake in middle adulthood has been linked to an increased risk of premature death from chronic diseases driven by cardiovascular disease mortality.

The present findings are consistent with those observed for protein intakes in older adulthood, Dr. Ardisson Korat said.

“This study underscores the health advantages for midlife adults consuming adequate dietary protein — particularly plant protein — as one component of pursuing a healthy lifestyle,” said Douglas R. Dirschl, MD, chair of orthopedic surgery at Baylor College of Medicine in Houston, Texas. Most Americans consume adequate amounts of protein, but according to Dr. Dirschl, who treats many older patients for osteoporotic fractures and other musculoskeletal conditions, many US diets are subpar in this nutrient.

While protein is essential for bone and muscle formation and maintenance, “a surprising number of Americans are protein deficient, even those who seem hale and are overweight,” he said.


 

Dietary Recommendations for Midlife Patients

Physicians should therefore advise midlife patients to meet or perhaps modestly exceed the recommended dietary allowance (RDA) for protein of 0.8 g/kg per day and to make plant protein a substantial component of daily dietary protein intake, Dr. Dirschl said.

Luke D. Kim, MD, MEd, a geriatrician at the Cleveland Clinic in Cleveland, Ohio, noted that patients with lower socioeconomic status or with difficulty in day-to-day functioning are likely to have suboptimal protein intake. Such patients may need encouragement to eat more protein. “But we should keep in mind that showing a higher associated odds ratio of better health with increased protein take does not mean causality,” he said.

According to Rachel L. Amdur, MD, an internist at Northwestern Medicine in Chicago, Illinois, the long-term follow-up data from the NHS are uniquely helpful. “Middle-aged persons may think they no longer need much dietary protein and need to be reminded. Sometimes eating carbohydrates is just easier,” she said in an interview. Physicians need to asses and counsel patients on nutrition at all stages of life. “As I tell my patients, it’s best to think of your future self now.”

In agreement is Louis J. Morledge, MD, an internist at Northwell Health in New York City. “I firmly counsel my patients about adequate and often increased protein intake in middle life. But this is always within a larger framework of overall nutritional health.” He added that middle-aged persons often find themselves “stuck in food ruts,” and one of his clinical focuses is to advise patients about the importance of healthier food choices so they can better adjust to mental, emotional, physical, and skeletal changes as they age.
 

Study Details

The NHS analysis drew on prospective data from 48,762 nurses under age 60 in 1984. Total protein, animal protein, dairy protein, and plant protein were derived from validated food-frequency questionnaires.

Adjusting for lifestyle, demographics, and health status, the investigators identified 3721 (7.6% of cohort) eligible participants. The mean age of participants at baseline was 48.6 years; 38.6% had body mass indexes (BMI; in kg/m²) greater than 25; 22.9% were current smokers; and 88.2% were married.

Healthy aging was defined as freedom from 11 major chronic diseases, good mental health, and no impairments in cognitive or physical function, as assessed in the 2014 or 2016 NHS participant questionnaires. Diseases/treatments included cancer, type 2 diabetes, myocardial infarction, coronary artery bypass graft or coronary angioplasty, congestive heart failure, stroke, kidney failure, chronic obstructive pulmonary disease, Parkinson disease, multiple sclerosis, and amyotrophic lateral sclerosis.

Mean total protein consumption as a percentage of energy was 18.3% (standard deviation 3%), slightly higher than the average 16% in the US diet. Of this, 13.3% derived from animals, 3.6% from dairy products, and 4.9% from plants.

Total protein intake was positively associated with higher education levels, being physically active, higher BMI, and a baseline history of hypertension and hypercholesterolemia. Conversely, total protein intake was inversely associated with intakes of total carbohydrates, nuts, alcohol, and sugar-sweetened beverages.

The associations between protein intake and healthy aging are complex and not fully understood, the authors stated.
 

Effects of Protein Intake

In studies of older adult populations lower protein intake has been associated with lean mass loss. Animal protein supplementation studies in older adults have shown lean mass gains potentially related to amino acid composition.

In terms of mechanisms, evidence suggests that protein-related activation of the rapamycin complex 1 pathway may play a role, the authors suggested. The activity of this signaling pathway decreases with age.

Rapamycin, a compound used to prevent organ transplant rejection, has been associated with delayed aging. In the body, dietary protein and exercise activate this pathway, thereby stimulating muscle protein synthesis and possibly improving physical function.

As for the differential associations of plant and animal protein on the chronic disease domain of the healthy aging phenotype, Dr. Ardisson Korat and coauthors said plant protein has been associated with favorable levels of important risk factors for cardiometabolic diseases, such as reduced LDL cholesterol, lower blood pressure, and insulin sensitivity, as well as decreased levels of proinflammatory markers.

Conversely, total and animal protein intakes have been positively associated with concentrations of insulin-like growth factor 1, which is implicated in the growth of malignant cells in breast and prostate tissue.

This study is the first step in evaluating the long-term health effect of protein intake in midlife, the relevant development window for most chronic conditions, the NHS study authors said. More research is needed, however, to corroborate the study findings in other populations and identify underlying mechanisms.

This study was supported by the USDA Agricultural Research Service and the National Institutes of Health. The authors reported no conflicts of interest. The commentators disclosed no relevant competing interests.

Intake of protein, especially from plants, in middle age is associated with higher odds of healthy aging and positive mental and physical health status in older women, a recent analysis of the Nurses’ Health Study (NHS) data suggests.

The study is said to be the first to examine the long-term impact of midlife protein consumption on later health status.

Writing in the American Journal of Clinical Nutrition, a team led by Andres V. Ardisson Korat, DSc, a nutritional epidemiologist at the USDA Human Nutrition Research Center on Aging at Tufts University in Boston, Massachusetts, found the following midlife protein–related odds ratios (ORs) for later healthy aging measured at ages 70-93.

For each 3% energy increment from various protein sources:

• 1.05 (95% confidence interval, 1.01-1.10) for total protein
• 1.07 (1.02-1.11) for animal protein
• 1.14 (1.06-1.23) for dairy protein
• 1.38 (1.24-1.54) for plant protein 

In substitution analyses, significant positive associations were observed for the isocaloric replacement of animal or dairy protein, carbohydrate, or fat with plant protein — with increased ORs for healthy aging of 1.22-1.58 for each 3% of energy replacement.

On the measure of physical function, for example, replacing calories from all macronutrient variables with equivalent calories from plant protein was associated with 20%-60% higher odds of having no physical function limitations.

Medicare will now cover the use of an AI-based test for prostate cancer that can predict which men will benefit from potentially disabling androgen deprivation therapy.

The Centers for Medicare & Medicare Services (CMS) on January 1 approved the payment rate for ArteraAI as a clinical diagnostic laboratory test. The test is the first that can both predict therapeutic benefit and prognosticate long-term outcomes in localized prostate cancer. 

Daniel Spratt, MD, chair of radiation oncology at UH Seidman Cancer Center in Cleveland, who has been involved in researching ArteraAI, told this news organization that the test improves risk stratification or prognostication over standard clinical and pathologic tools, such as prostate-specific antigen, Gleason score, and T-stage, or risk groupings such as those from the National Comprehensive Cancer Network (NCCN).

“Medicare approval allows this test to reach more patients without the financial burden of covering the test out of pocket. The test is found among other tests in NCCN guidelines as a tool to improve risk stratification and personalization of treatment,” said Dr. Spratt, who serves on the network’s prostate cancer panel.

ArteraAI combines a patient’s standard clinical and pathologic information into an algorithm, alongside a digitized image analysis of the patients’ prostate biopsy. The result is a score that estimates a patient’s risk of developing metastasis or dying from prostate cancer.

Dr. Spratt was the lead author of article last June in NEJM Evidence that validated ArteraAI. He said ArteraAI is 80% accurate as a prognostic test compared with 65% accuracy using NCCN stratification systems. 

The AI test spares about two thirds of men with intermediate-risk prostate cancer who are starting radiation therapy from androgen deprivation and its side effects, such as weight gain, breast enlargement, hot flashes, heart disease, and brain problems, Dr. Spratt added. 

Andre Esteva, CEO and co-founder of San Francisco-based ArteraAI, said, “After someone is diagnosed with localized prostate cancer, deciding on a treatment can feel very overwhelming as there are so many factors to consider. During this time, knowledge is power, and having detailed, personalized information can increase confidence when making these challenging decisions. The ArteraAI Prostate Test was developed with this in mind and can predict whether a patient will benefit from hormone therapy and estimate long-term outcomes.”

Bruno Barrey is one of Dr. Spratt’s patients. Barrey, a robotics engineer from suburban Detroit who was transitioning from active surveillance with Gleason 3+4 intermediate-risk prostate cancer to radiation therapy, said, “I was concerned about the side effects from androgen-deprivation therapy. I was relieved that the AI test allowed me to avoid hormone therapy.”

Dr. Spratt reported working with NRG Oncology, a clinical trials group funded by the National Cancer Institute, and as an academic collaborator with ArteraAI.

About 20% of US physicians took less than 1 week of vacation in the previous year, a new study found. When doctors did go on vacation, 70% reported working on their days off to handle patient-related tasks.

Burnout was more likely among doctors who worked more during vacations and lacked coverage in responding to electronic health messages from patients, according to the cross-sectional study, which was published on January 12, 2024, in JAMA Network Open.“It’s important to provide physicians with adequate time to disconnect from work and recharge,” said study coauthor Tait Shanafelt, MD, chief wellness officer at Stanford Medicine, in an interview.

The study’s conclusion that most US physicians work on their days off “is a marker of inadequate staffing, suboptimal teamwork, and poorly designed coverage systems,” he added. “Simply allocating people a number of vacation days is not enough.”

According to Dr. Shanafelt, there’s been little research into vacation’s impact on physician well-being. However, it is clear that work overload and exhaustion are major problems among American physicians. “Inadequate time off may magnify these challenges.”

Research suggests that physicians suffer more burnout than other US workers even after adjusting for confounders, he said. Extensive evidence shows that burnout in physicians contributes to medical errors and erodes quality of care and patient satisfaction, he added.

For the new study, researchers mailed surveys to 3671 members of the American Medical Association from 2020 to 2021, and 1162 (31.7%) responded. Another 6348 (7.1%) responded to an email survey sent to 90,000 physicians. An analysis suggested the respondents were representative of all US practicing physicians. 

Among 3024 respondents who responded to a subsurvey about vacations, about 40% took more than 15 days of vacation over the past year, about 40% took 6-15 days, and about 20% took 5 or fewer days. 

Fewer than half of physicians said their electronic health record (EHR) inboxes were fully covered by others while they were away. About 70% said they worked while on vacation, with nearly 15% working an hour or more each day.

Emergency physicians were the least likely and anesthesiologists were the most likely to take at least 15 days of vacation per year, according to the study. 

Women were more likely than men to work 30 or more minutes a day on vacation. Physicians aged 65 years and older were more likely to take 15 or more days of vacation per year than those under 35 years.

An adjusted analysis linked complete EHR inbox coverage to lower odds of taking time during vacation to work (odds ratio [OR], 0.68; 95% CI, 0.57-0.80).

“For many, difficulty finding clinical coverage, lack of EHR inbox coverage, and returning to an overwhelming backlog of EHR inbox work at were identified as barriers to taking vacation,” Dr. Shanafelt said.

Researchers linked lower rates of burnout to taking more than 3 weeks of vacation per year (OR, 0.59-0.66, depending on time spent; 95% CI, 0.40-0.98) vs none. They also linked less burnout to full EHR inbox coverage while on vacation (OR, 0.74; 95% CI, 0.63-0.88) and more burnout to spending 30 minutes or more on work while on a typical vacation day (OR, 1.58-1.97, depending on time spent; 95% CI, 1.22-2.77). 

Study limitations include the low participation rate and lack of insight into causation. It’s not clear how burnout and less vacation time are related and whether one causes the other, Shanafelt said. “It is possible there are a number of interacting factors rather than a simple, linear relationship.”

In an interview, Lazar J. Greenfield, Jr., MD, PhD, professor and chairman of neurology at UConn Health, Farmington, Connecticut, said his department encourages clinicians to plan vacations well ahead of time, and “we make a real strong effort to make sure that people are fully covered and someone has their Epic inbox.”

Dr. Greenfield, who wasn’t involved in the new study, recommended that physicians plan active vacations, so they have less downtime to catch up on work matters. But he acknowledged that stepping away from emails can be difficult, especially when physicians fear pileups of work upon their return or don’t want to annoy patients with tardy responses.

“They have a hard time disengaging from their moral obligations to patients,” he said. “Another issue, particularly in my field of neurology, is that there’s a lot of subspecialties. Finding somebody with the exact subspecialty and expertise to cover a very specific patient population they treat can be really hard.”

The Stanford WellMD Center, Mayo Clinic Department of Medicine Program on Physician Well-being, and American Medical Association funded the study.

Dr. Shanafelt discloses coinventing the Well-Being Index and its derivatives with another study author; Mayo Clinic licensed the Well-Being Index and pays them royalties outside the submitted work. Dr. Shanafelt also reported support for grand rounds, lectures, and advising for healthcare organizations outside the submitted work. Other authors reported personal fees from Marvin Behavioral Health and grants from the National Institute of Nursing Research, National Science Foundation, and Med Ed Solutions. 

Dr. Greenfield had no disclosures.

About 20% of US physicians took less than 1 week of vacation in the previous year, a new study found. When doctors did go on vacation, 70% reported working on their days off to handle patient-related tasks.

Burnout was more likely among doctors who worked more during vacations and lacked coverage in responding to electronic health messages from patients, according to the cross-sectional study, which was published on January 12, 2024, in JAMA Network Open.“It’s important to provide physicians with adequate time to disconnect from work and recharge,” said study coauthor Tait Shanafelt, MD, chief wellness officer at Stanford Medicine, in an interview.

The study’s conclusion that most US physicians work on their days off “is a marker of inadequate staffing, suboptimal teamwork, and poorly designed coverage systems,” he added. “Simply allocating people a number of vacation days is not enough.”

According to Dr. Shanafelt, there’s been little research into vacation’s impact on physician well-being. However, it is clear that work overload and exhaustion are major problems among American physicians. “Inadequate time off may magnify these challenges.”

Research suggests that physicians suffer more burnout than other US workers even after adjusting for confounders, he said. Extensive evidence shows that burnout in physicians contributes to medical errors and erodes quality of care and patient satisfaction, he added.

For the new study, researchers mailed surveys to 3671 members of the American Medical Association from 2020 to 2021, and 1162 (31.7%) responded. Another 6348 (7.1%) responded to an email survey sent to 90,000 physicians. An analysis suggested the respondents were representative of all US practicing physicians. 

Among 3024 respondents who responded to a subsurvey about vacations, about 40% took more than 15 days of vacation over the past year, about 40% took 6-15 days, and about 20% took 5 or fewer days. 

Fewer than half of physicians said their electronic health record (EHR) inboxes were fully covered by others while they were away. About 70% said they worked while on vacation, with nearly 15% working an hour or more each day.

Emergency physicians were the least likely and anesthesiologists were the most likely to take at least 15 days of vacation per year, according to the study. 

Women were more likely than men to work 30 or more minutes a day on vacation. Physicians aged 65 years and older were more likely to take 15 or more days of vacation per year than those under 35 years.

An adjusted analysis linked complete EHR inbox coverage to lower odds of taking time during vacation to work (odds ratio [OR], 0.68; 95% CI, 0.57-0.80).

“For many, difficulty finding clinical coverage, lack of EHR inbox coverage, and returning to an overwhelming backlog of EHR inbox work at were identified as barriers to taking vacation,” Dr. Shanafelt said.

Researchers linked lower rates of burnout to taking more than 3 weeks of vacation per year (OR, 0.59-0.66, depending on time spent; 95% CI, 0.40-0.98) vs none. They also linked less burnout to full EHR inbox coverage while on vacation (OR, 0.74; 95% CI, 0.63-0.88) and more burnout to spending 30 minutes or more on work while on a typical vacation day (OR, 1.58-1.97, depending on time spent; 95% CI, 1.22-2.77). 

Study limitations include the low participation rate and lack of insight into causation. It’s not clear how burnout and less vacation time are related and whether one causes the other, Shanafelt said. “It is possible there are a number of interacting factors rather than a simple, linear relationship.”

In an interview, Lazar J. Greenfield, Jr., MD, PhD, professor and chairman of neurology at UConn Health, Farmington, Connecticut, said his department encourages clinicians to plan vacations well ahead of time, and “we make a real strong effort to make sure that people are fully covered and someone has their Epic inbox.”

Dr. Greenfield, who wasn’t involved in the new study, recommended that physicians plan active vacations, so they have less downtime to catch up on work matters. But he acknowledged that stepping away from emails can be difficult, especially when physicians fear pileups of work upon their return or don’t want to annoy patients with tardy responses.

“They have a hard time disengaging from their moral obligations to patients,” he said. “Another issue, particularly in my field of neurology, is that there’s a lot of subspecialties. Finding somebody with the exact subspecialty and expertise to cover a very specific patient population they treat can be really hard.”

The Stanford WellMD Center, Mayo Clinic Department of Medicine Program on Physician Well-being, and American Medical Association funded the study.

There’s no question that glucagon-like peptide 1 (GLP-1) agonists represent a major advance in the treatment of obesity for patients with or without diabetes. In clinical trials, participants lost 15%-20% of their body weight, depending on the drug.

But studies also have shown that once people stop taking these drugs — either by choice, because of shortage, or lack of access — they regain most, if not all, the weight they lost.

Arguably more frustrating is the fact that those who continue on the drug eventually reach a plateau, at which point, the body seemingly stubbornly refuses to lose more weight. Essentially, it stabilizes at its set point, said Fatima Cody Stanford, MD, MPH, MPA, MBA, an obesity medicine physician at Massachusetts General Hospital and associate professor at Harvard Medical School in Boston.
 

‘Tug of War’

Every study of weight loss drugs done over the past 40 years or so shows a plateau, Dr. Stanford told this news organization. “If you look at the phentermine/topiramate studies, there’s a plateau. If you look at the bupropion/naltrexone studies, there’s a plateau. Or if we look at bariatric surgery, there’s a plateau. And it’s the same for the newer GLP-1 drugs.”

The reason? “It really depends on where the body gets to,” Dr. Stanford said. “The body knows what it needs to do to maintain itself, and the brain knows where it’s supposed to be. And when you lose weight and reach what you feel is a lower set point, the body resists.”

When the body goes below its set point, the hunger hormone ghrelin, which is housed in the brain, gets reactivated and gradually starts to reemerge, she explained. GLP-1, which is housed in the distal portion of the small intestine and in the colon, also starts to reemerge over time.

“It becomes kind of a tug of war” between the body and whatever weight loss strategy is being implemented, from drugs to surgery to lifestyle changes, Dr. Stanford said. “The patient will start to notice changes in how their body is responding. Usually, they’ll say they don’t feel like the treatment is working the same. But the treatment is working the same as it’s always been working — except their body is now acclimated to it.”

Anne L. Peters, MD, CDE, professor and clinical scholar, Keck School of Medicine of the University of Southern California, and director, agreed that in the simplest terms, a plateau occurs because “the body becomes more and more used to” the weight loss intervention.

However, when you lose weight, you lose both fat mass and lean body mass, and lean body mass is the metabolically active part of your body, explained Dr. Peters. “That’s what burns and basically makes up your basal metabolic rate.”

With weight loss, the metabolism slows down, she said. If patients need 2000 calories a day to survive at a certain weight and then lose 50 pounds, they may then need only a 1000 calories a day. “With any obesity treatment, you reach a point at which your metabolic rate and your daily caloric requirements become equal, and you stop losing weight, even though your daily caloric requirement is less than it was when your weight was higher.”
 

Managing the Plateau

Several strategies can be used to help patients break through a plateau. One is to try multiple weight loss agents with different targets — something often done in the real world, Dr. Stanford said. “You don’t see this in the studies, which are focused on just one drug, but many of our patients are on combination therapy. They’re on a GLP-1 drug plus phentermine/topiramate plus metformin, and more. They’re usually on three, four, five drugs, similar to what we would see with resistant hypertension.”

If a patient plateaus on a GLP-1 drug, Dr. Stanford might add phentermine. When the patient reaches a plateau on phentermine, she would switch again to another agent. “The goal is to use agents that treat different receptors in the brain,” she said. “You would never use two GLP-1 agonists; you would use the GLP-1, and then something that treats norepinephrine, for example.”

At the same time, Dr. Peters noted, “try to get them off the drugs that cause weight gain, like insulin and sulfonylurea agents.”

Tapering the GLP-1 dose can also help, Dr. Peters said. However, she added, “If I’m using a GLP-1 drug for type 2 diabetes, it’s different than if I’m using it just for weight loss. With type 2 diabetes, if you taper too much, the blood sugar and weight will go back up, so you need to reach a balance.”

Dr. Peters has successfully tapered patients from a 2-mg dose down to 1 mg. She has also changed the strategy for some — ie, the patient takes the drug every other week instead of every week. “I even have a patient or two who just take it once a month and that seems to be enough,” she said. “You want to help them be at the dose that maintains their weight and keeps them healthy with the least possible medication.”

Emphasizing lifestyle changes is also important, she said. Although resistance training won’t necessarily help with weight loss, “it’s critical to maintaining lean body mass. If people keep losing and regaining weight, they’re going to lose more and more lean body mass and gain the weight back primarily as fat mass. So, their exercise should include about half aerobic activity and half resistance training.”
 

Long-term Journey

Setting appropriate expectations is a key part of helping patients accept and deal with a plateau. “This is long-term, lifelong journey,” Dr. Stanford said. “We need to think about obesity as a complex, multifactorial chronic disease, like we think about hypertension or type 2 diabetes or hyperlipidemia.”

Furthermore, and in keeping with that perspective, emerging evidence is demonstrating that GLP-1 drugs also have important nonglycemic benefits that can be achieved and maintained, Dr. Peters said. “Obviously weight loss matters, and weight loss is good for you if you’re overweight or obese. But now we know that GLP-1 drugs have wonderful benefits for the heart as well as renal function.” These are reasons to continue the drugs even in the face of a plateau.

One of Dr. Peters’ patients, a physician with type 2 diabetes, had “fought with her weight her whole life. She’s been on one or another GLP-1 drug for more than 15 years, and while none seem to impact her weight, she’s gone from having relatively poorly controlled to now beautifully controlled diabetes,” Dr. Peters said. “Even if she hasn’t lost, she’s maintained her weight, a benefit since people tend to gain weight as they get older, and she hasn’t gained.”

Another patient was disabled, on oxygen, and had recurrent pulmonary embolisms. “She weighed 420 pounds, and I put her on semaglutide because she was too sick to be considered for bariatric surgery.” When that didn’t work, Dr. Peters switched her to tirzepatide, gradually increasing the dose; the patient lost 80 pounds, her emboli are gone, she can walk down the street, and went back to work.

“Part of why she could do that is that she started exercising,” Dr. Peters noted. “She felt so much better from the drug-related weight loss that she began to do things that help enhance weight loss. She became happier because she was no longer homebound.”

This points to another element that can help patients break through a plateau over time, Dr. Peters said — namely, behavioral health. “The more people lose weight, the more they feel better about themselves, and that may mean that they take better care of themselves. The psychological part of this journey is as important as anything else. Not everyone has the same response to these agents, and there are all sorts of issues behind why people are overweight that physicians can’t ignore.

“So, in addition to managing the drugs and lifestyle, it’s important to make sure that people access the behavioral health help they need, and that once they break through a plateau, they don’t develop an eating disorder or go to the opposite extreme and become too thin, which has happened with some of my patients,” she said. “We need to remember that we’re not just giving patients a miraculous weight loss. We’re helping them to be healthier, mentally as well as physically.”

Dr. Stanford disclosed that she had been a consultant for Calibrate, GoodRx, Pfizer, Eli Lilly, Boehringer Ingelheim, Gelesis, Vida Health, Life Force, Ilant Health, Melli Cell, and Novo Nordisk. Dr. Peters disclosed that she had been a consultant for Vertex, Medscape Medical News, and Lilly; received funding from Abbott and Insulet; and had stock options in Omada Health.

The relationship between lipid levels and the development of dementia is an evolving but confusing landscape.

“This is an incredibly complex area, and there really isn’t a clear consensus on this subject because different lipid classes reflect different things,” according to Betsy Mills, PhD, assistant director of aging and Alzheimer’s prevention at the Alzheimer’s Drug Discovery Foundation.

Some studies suggest that excessive lipid levels may increase the risk of developing dementia and Alzheimer’s disease (AD). Others imply that elevated low-density lipoprotein (LDL) cholesterol or even triglycerides may offer some protection against subsequent dementia whereas higher levels of high-density lipoprotein (HDL) cholesterol, hitherto thought to be protective, may have a deleterious effect.

“It depends on what lipids you’re measuring, what you’re using to measure those lipids, what age the person is, and multiple other factors,” Dr. Mills told this news organization.

Teasing out the variables and potential mechanisms for the association between lipids and dementia risk necessitates understanding the role that lipids play in the healthy brain, the negative impact of brain lipid dysregulation, and the interplay between cholesterol in the central nervous system (CNS) and the cholesterol in the rest of the body.

 

Beyond Amyloid

The role of lipids in AD risk has historically been “overlooked,” says Scott Hansen, PhD, associate professor, Department of Molecular Medicine, Herbert Wertheim UF Scripps Institute for Biomedical Innovation and Technology, Florida.

“The common narrative is that amyloid is the culprit in AD and certainly that’s the case in familial AD,” he told this news organization. “It’s been assumed that because amyloid deposits are also found in the brains of people with late-onset AD — which is the vast majority of cases — amyloid is the cause, but that’s not clear at all.”

The “limited clinical success” of aducanumab, its “extremely small efficacy” — despite its obvious success in eradicating the amyloid plaques — suggests there’s “much more to the story than amyloid.”

He and a growing community of scientists recognize the role of inflammation and lipids. “The major finding of my lab is that cholesterol actually drives the synthesis of amyloid via inflammation. In other words, amyloid is downstream of cholesterol. Cholesterol drives the inflammation, and the inflammation drives amyloid,” he said.
 

‘Lipid Invasion Model’

Because the brain is an incredibly lipid-rich organ, Dr. Mills said that “any dysregulation in lipid homeostasis will impact the brain because cholesterol is needed for the myelin sheaths, cell membranes, and other functions.”

A healthy brain relies upon healthy lipid regulation, and “since the first description of AD over 100 years ago, the disease has been associated with altered lipids in the brain,” Dr. Hansen noted.

He cited the “ lipid invasion model” as a way of understanding brain lipid dysregulation. This hypothesis posits that AD is driven by external lipids that enter the brain as a result of damage to the blood-brain barrier (BBB).

“Cholesterol in the brain and cholesterol in the periphery — meaning, in the rest of the body, outside the brain — are separate,” Dr. Hansen explained. “The brain produces its own cholesterol and keeps tight control of it.”

Under normal circumstances, cholesterol from the diet doesn’t enter the brain. “Each pool of cholesterol — in the brain and in the periphery — has its own distinct regulatory mechanisms, target cells, and transport mechanisms.”

When the BBB has been compromised, it becomes permeable, allowing LDL cholesterol to enter the brain, said Dr. Hansen. Then the brain’s own lipoproteins transport the invading cholesterol, allowing it to be taken up by neurons. In turn, this causes neuronal amyloid levels to rise, ultimately leading to the creation of amyloid-b plaques. It also plays a role in tau phosphorylation. Both are key features of AD pathology.

Elevated levels of cholesterol and other lipids have been found in amyloid plaques, Dr. Hansen noted. Moreover, studies of brains of patients with AD have pointed to BBB damage.

And the risk factors for AD overlap with the risk factors for damage to the BBB (such as, aging, brain trauma, hypertension, stress, sleep deprivation, smoking, excess alcohol, obesity, diabetes, and APOE4 genotype), according to the lipid invasion model paper cited by Dr. Hansen.
 

‘Chicken and Egg’

“There is a strong link between the brain and the heart, and we know that cardiovascular risk factors have an overlap with dementia risk factors — especially vascular dementia,” said Dr. Mills. 

She explained that an atherogenic lipid profile results in narrowing of the arteries, with less blood reaching the brain. “This can lead to stress in the brain, which drives inflammation and pathology.”

But cholesterol itself plays an important role in inflammation, Dr. Hansen said. In the periphery, it is “part of an integral response to tissue damage and infection.”

In the brain, once cholesterol is synthesized by the astrocytes, it is transported to neurons via the apolipoprotein E (APOE) protein, which plays a role in brain cholesterol homeostasis, Dr. Mills explained. Those with the ε4 allele of APOE (APOE4) tend to have faultier transport and storage of lipids in the brain, relative to the other APOE variants.

It’s known that individuals with APOE4 are particularly vulnerable to late-onset AD, Dr. Hansen observed. By contrast, APOE2 has a more protective effect. “Most people have APOE3, which is ‘in between,’ ” he said.

When there is neuronal uptake of “invading cholesterol,” not only is amyloid produced but also neuroinflammatory cytokines, further driving inflammation. A vicious cycle ensues: Cholesterol induces cytokine release; and cytokine release, in turn, induces cholesterol synthesis — which “suggests an autocatalytic function of cholesterol in the escalation of inflammation,” Dr. Hansen suggested. He noted that permeability of the BBB also allows inflammatory cytokines from elsewhere in the body to invade the brain, further driving inflammation.

Dr. Mills elaborated: “We know that generally, in dementia, there appear to be some changes in cholesterol metabolism in the brain, but it’s a chicken-and-egg question. We know that as the disease progresses, neurons are dying and getting remodeled. Do these changes have to do with the degenerative process, or are the changes in the cholesterol metabolism actually driving the degenerative disease process? It’s probably a combination, but it’s unclear at this point.”
 

Lipids in Plasma vs CSF

Dr. Mills explained that HDL particles in the brain differ from those in the periphery. “In the CNS, you have ‘HDL-like particles,’ which are similar in size and composition [to HDL in the periphery] but aren’t the same particles.” The brain itself generates HDL-like lipoproteins, which are produced by astrocytes and other glial cells and found in cerebrospinal fluid (CSF).

Dyslipidemia in the periphery can be a marker for cardiovascular pathology. In the brain, “it can be an indication that there is active damage going on, depending on which compartment you’re looking at.”

She noted that plasma lipid levels and brain CSF lipid levels are “very different.” Research suggests that HDL in the CSF exhibits similar heterogeneity to plasma HDL, but these CSF lipoproteins present at 100-fold lower concentrations, compared to plasma HDL and have unique combinations of protein subpopulations. Lipidomics analysis studies show that these compartments “get very different readings, in terms of the predominant lipid disease state, and they are regulated differently from the way lipids in the periphery are regulated.” 

In the brain, the cholesterol “needs to get shuttled from glial cells to neurons,” so defects in the transport process can disrupt overall brain homeostasis, said Dr. Mills. But since the brain system is separate from the peripheral system, measuring plasma lipids is more likely to point to cardiovascular risks, while changes reflected in CSF lipids are “more indicative of alteration in lipid homeostasis in the brain.”
 

HDL and Triglycerides: A Complicated Story

Dr. Mills noted that HDL in the periphery is “very complicated,” and the idea that HDL, as a measure on its own, is “necessarily ‘good’ isn’t particularly informative.” Rather, HDL is “extremely heterogeneous, very diverse, has different lipid compositions, different classes, and different modifications.” For example, like oxidized LDL, oxidized HDL is also “bad,” preventing the HDL from having protective functions.

Similarly, the apolipoproteins associated with HDL can affect the function of the HDL. “Our understanding of the HDL-like particles in the CNS is limited, but we do understand the APOE4 link,” Dr. Mills said. “It seems that the HDL-like particles containing APOE2 or APOE3 are larger and are more effective at transferring the lipids and cholesterol linked to them relative to APOE4-containing particles.” 

Because HDL is more complex than simply being “good,” measuring HDL doesn’t “give you the full story,” said Dr. Mills. She speculates that this may be why there are studies suggesting that high levels of HDL might not have protective benefits and might even be detrimental. This makes it difficult to look at population studies, where the different subclasses of HDL are not necessarily captured in depth. 

Dr. Mills pointed to another confounding factor, which is that much of the risk for the development of AD appears to be related to the interaction of HDL, LDL, and triglycerides. “When you look at each of these individually, you get a lot of heterogeneity, and it’s unclear what’s driving what,” she said.

An advantage of observational studies is that they give information about which of these markers are associated with trends and disease risks in specific groups vs others. 

“For example, higher levels of triglycerides are associated with cardiovascular risk more in women, relative to men,” she said. And the triglyceride-to-HDL ratio seems “particularly robust” as a measure of cardiovascular health and risk. 

The interpretation of associations with triglycerides can be “tricky” and “confusing” because results differ so much between studies, she said. “There are differences between middle age and older age, which have to do with age-related changes in metabolism and lipid metabolism and not necessarily that the markers are indicating something different,” she said.

Some research has suggested that triglycerides may have a protective effect against dementia, noted Uma Naidoo, MD, director of nutritional and lifestyle psychiatry, Massachusetts General Hospital, and director of nutritional psychiatry at MGH Academy.

This may be because the brain “runs mostly on energy from burning triglycerides,” suggested Dr. Naidoo, author of the books Calm Your Mind With Food and This Is Your Brain on Food.

In addition, having higher levels of triglycerides may be linked with having overall healthier behaviors, Dr. Naidoo told this news organization.

Dr. Mills said that in middle-aged individuals, high levels of LDL-C and triglycerides are “often indicative of more atherogenic particles and risk to cardiovascular health, which is a generally negative trajectory. But in older individuals, things become more complicated because there are differences in terms of clearance of some of these particles, tissue clearance and distribution, and nutrient status. So for older individuals, it seems that fluctuations in either direction—either too high or too low—tend to be more informative that some overall dysregulation is going on the system.” 

She emphasized that, in this “emerging area, looking at only one or two studies is confusing. But if you look at the spectrum of studies, you can see a pattern, which is that the regulation gets ‘off,’ as people age.”

 

The Potential Role of Statins

Dr. Mills speculated that there may be “neuroprotective benefits for some of the statins which appear to be related to cardiovascular benefits. But at this point, we don’t have any clear data whether statins actually directly impact brain cholesterol, since it’s a separate pool.”

They could help “by increasing blood flow and reducing narrowing of the arteries, but any direct impact on the brain is still under investigation.”

Dr. Hansen pointed to research suggesting statins taken at midlife appear to be cardioprotective and may be protective of brain health as well, whereas statins initiated in older age do not appear to have these benefits.

He speculated that one reason statins seem less helpful when initiated later in life is that the BBB has already been damaged by systemic inflammation in the periphery, and the neuroinflammatory process resulting in neuronal destruction is already underway. “I think statins aren’t going to fix that problem, so although lowering cholesterol can be helpful in some respects, it might be too late to affect cognition because the nerves have already died and won’t grow back.”
 

Can Dietary Approaches Help?

Dr. Naidoo said that when looking at neurologic and psychiatric disease, “it’s important to think about the ‘long game’ — how can we improve our blood and cardiovascular health earlier in life to help potentiate healthy aging?”

From a nutritional psychiatry standpoint, Dr. Naidoo focuses on nourishing the gut microbiome and decreasing inflammation. “A healthy and balanced microbiome supports cognition, while the composition of gut bacteria is actually drastically different in patients with neurological diseases, such as AD.” 

She recommends a nutrient-dense, anti-inflammatory diet including probiotic-rich foods (such as kimchi, sauerkraut, plain yogurt, and miso). Moreover, “the quality and structure of our fatty acids may be relevant as well: Increasing our intake of polyunsaturated fatty acids and avoiding processed fats like trans fats and hydrogenated oils may benefit our overall brain health.”

Dr. Naidoo recommends extra-virgin olive oil as a source of healthy fat. Its consumption is linked to lower incidence of AD by way of encouraging autophagy, which she calls “our own process of “cellular cleanup.’”

Dr. Naidoo believes that clinicians’ guidance to patients should “focus on healthy nutrition and other lifestyle practices, such as exercise, outdoor time, good sleep, and stress reduction.” 

Dr. Mills notes the importance of omega-3 fatty acids, such as docosahexaenoic acid (DHA) , for brain health. “DHA is a major lipid component of neuronal membranes,” she said. “Because of inefficiencies in metabolism with APOE4, people tend to metabolize more of the lipids on the membranes themselves, so they have higher lipid membrane turnover and a greater need to supplement. Supplementing particularly through diet, with foods such as fatty fish rich in omega-3, can help boost the levels to help keep neuronal membranes intact.”
 

What This Means for the Clinician

“At this point, we see all of these associations between lipids and dementia, but we haven’t worked out exactly what it means on the individual level for an individual patient,” said Dr. Mills. Certainly, the picture is complex, and the understanding is growing and shifting. “The clinical applications remain unclear.”

One potential clinical take-home is that clinicians might consider tracking lipid levels over time. “If you follow a patient and see an increase or decrease [in lipid levels], that can be informative.” Looking at ratios of lipids might be more useful than looking only at a change in a single measure. “If you see trends in a variety of measures that track with one another, it might be more of a sign that something is potentially wrong.” 

Whether the patient should first try a lifestyle intervention or might need medication is a “personalized clinical decision, depending on the individual, their risk factors, and how their levels are going,” said Dr. Mills. 

Dr. Mills, Dr. Hansen, and Dr. Naidoo declared no relevant financial relationships.

The relationship between lipid levels and the development of dementia is an evolving but confusing landscape.

“This is an incredibly complex area, and there really isn’t a clear consensus on this subject because different lipid classes reflect different things,” according to Betsy Mills, PhD, assistant director of aging and Alzheimer’s prevention at the Alzheimer’s Drug Discovery Foundation.

Some studies suggest that excessive lipid levels may increase the risk of developing dementia and Alzheimer’s disease (AD). Others imply that elevated low-density lipoprotein (LDL) cholesterol or even triglycerides may offer some protection against subsequent dementia whereas higher levels of high-density lipoprotein (HDL) cholesterol, hitherto thought to be protective, may have a deleterious effect.

“It depends on what lipids you’re measuring, what you’re using to measure those lipids, what age the person is, and multiple other factors,” Dr. Mills told this news organization.

Teasing out the variables and potential mechanisms for the association between lipids and dementia risk necessitates understanding the role that lipids play in the healthy brain, the negative impact of brain lipid dysregulation, and the interplay between cholesterol in the central nervous system (CNS) and the cholesterol in the rest of the body.

 

Beyond Amyloid

The role of lipids in AD risk has historically been “overlooked,” says Scott Hansen, PhD, associate professor, Department of Molecular Medicine, Herbert Wertheim UF Scripps Institute for Biomedical Innovation and Technology, Florida.

“The common narrative is that amyloid is the culprit in AD and certainly that’s the case in familial AD,” he told this news organization. “It’s been assumed that because amyloid deposits are also found in the brains of people with late-onset AD — which is the vast majority of cases — amyloid is the cause, but that’s not clear at all.”

The “limited clinical success” of aducanumab, its “extremely small efficacy” — despite its obvious success in eradicating the amyloid plaques — suggests there’s “much more to the story than amyloid.”

He and a growing community of scientists recognize the role of inflammation and lipids. “The major finding of my lab is that cholesterol actually drives the synthesis of amyloid via inflammation. In other words, amyloid is downstream of cholesterol. Cholesterol drives the inflammation, and the inflammation drives amyloid,” he said.
 

‘Lipid Invasion Model’

Because the brain is an incredibly lipid-rich organ, Dr. Mills said that “any dysregulation in lipid homeostasis will impact the brain because cholesterol is needed for the myelin sheaths, cell membranes, and other functions.”

A healthy brain relies upon healthy lipid regulation, and “since the first description of AD over 100 years ago, the disease has been associated with altered lipids in the brain,” Dr. Hansen noted.

He cited the “ lipid invasion model” as a way of understanding brain lipid dysregulation. This hypothesis posits that AD is driven by external lipids that enter the brain as a result of damage to the blood-brain barrier (BBB).

“Cholesterol in the brain and cholesterol in the periphery — meaning, in the rest of the body, outside the brain — are separate,” Dr. Hansen explained. “The brain produces its own cholesterol and keeps tight control of it.”

Under normal circumstances, cholesterol from the diet doesn’t enter the brain. “Each pool of cholesterol — in the brain and in the periphery — has its own distinct regulatory mechanisms, target cells, and transport mechanisms.”

When the BBB has been compromised, it becomes permeable, allowing LDL cholesterol to enter the brain, said Dr. Hansen. Then the brain’s own lipoproteins transport the invading cholesterol, allowing it to be taken up by neurons. In turn, this causes neuronal amyloid levels to rise, ultimately leading to the creation of amyloid-b plaques. It also plays a role in tau phosphorylation. Both are key features of AD pathology.

Elevated levels of cholesterol and other lipids have been found in amyloid plaques, Dr. Hansen noted. Moreover, studies of brains of patients with AD have pointed to BBB damage.

And the risk factors for AD overlap with the risk factors for damage to the BBB (such as, aging, brain trauma, hypertension, stress, sleep deprivation, smoking, excess alcohol, obesity, diabetes, and APOE4 genotype), according to the lipid invasion model paper cited by Dr. Hansen.
 

‘Chicken and Egg’

“There is a strong link between the brain and the heart, and we know that cardiovascular risk factors have an overlap with dementia risk factors — especially vascular dementia,” said Dr. Mills.

She speculates that this may be why there are studies suggesting that high levels of HDL might not have protective benefits and might even be detrimental. This makes it difficult to look at population studies, where the different subclasses of HDL are not necessarily captured in depth. 

Dr. Mills pointed to another confounding factor, which is that much of the risk for the development of AD appears to be related to the interaction of HDL, LDL, and triglycerides. “When you look at each of these individually, you get a lot of heterogeneity, and it’s unclear what’s driving what,” she said.

An advantage of observational studies is that they give information about which of these markers are associated with trends and disease risks in specific groups vs others. 

“For example, higher levels of triglycerides are associated with cardiovascular risk more in women, relative to men,” she said. And the triglyceride-to-HDL ratio seems “particularly robust” as a measure of cardiovascular health and risk. 

The interpretation of associations with triglycerides can be “tricky” and “confusing” because results differ so much between studies, she said. “There are differences between middle age and older age, which have to do with age-related changes in metabolism and lipid metabolism and not necessarily that the markers are indicating something different,” she said.

Some research has suggested that triglycerides may have a protective effect against dementia, noted Uma Naidoo, MD, director of nutritional and lifestyle psychiatry, Massachusetts General Hospital, and director of nutritional psychiatry at MGH Academy.

This may be because the brain “runs mostly on energy from burning triglycerides,” suggested Dr. Naidoo, author of the books Calm Your Mind With Food and This Is Your Brain on Food.

In addition, having higher levels of triglycerides may be linked with having overall healthier behaviors, Dr. Naidoo told this news organization.

Dr. Mills said that in middle-aged individuals, high levels of LDL-C and triglycerides are “often indicative of more atherogenic particles and risk to cardiovascular health, which is a generally negative trajectory. But in older individuals, things become more complicated because there are differences in terms of clearance of some of these particles, tissue clearance and distribution, and nutrient status. So for older individuals, it seems that fluctuations in either direction—either too high or too low—tend to be more informative that some overall dysregulation is going on the system.” 

She emphasized that, in this “emerging area, looking at only one or two studies is confusing. But if you look at the spectrum of studies, you can see a pattern, which is that the regulation gets ‘off,’ as people age.”

 

The Potential Role of Statins

Dr. Mills speculated that there may be “neuroprotective benefits for some of the statins which appear to be related to cardiovascular benefits. But at this point, we don’t have any clear data whether statins actually directly impact brain cholesterol, since it’s a separate pool.”

They could help “by increasing blood flow and reducing narrowing of the arteries, but any direct impact on the brain is still under investigation.”

Dr. Hansen pointed to research suggesting statins taken at midlife appear to be cardioprotective and may be protective of brain health as well, whereas statins initiated in older age do not appear to have these benefits.

He speculated that one reason statins seem less helpful when initiated later in life is that the BBB has already been damaged by systemic inflammation in the periphery, and the neuroinflammatory process resulting in neuronal destruction is already underway. “I think statins aren’t going to fix that problem, so although lowering cholesterol can be helpful in some respects, it might be too late to affect cognition because the nerves have already died and won’t grow back.”
 

Can Dietary Approaches Help?

Dr. Naidoo said that when looking at neurologic and psychiatric disease, “it’s important to think about the ‘long game’ — how can we improve our blood and cardiovascular health earlier in life to help potentiate healthy aging?”

From a nutritional psychiatry standpoint, Dr. Naidoo focuses on nourishing the gut microbiome and decreasing inflammation. “A healthy and balanced microbiome supports cognition, while the composition of gut bacteria is actually drastically different in patients with neurological diseases, such as AD.” 

She recommends a nutrient-dense, anti-inflammatory diet including probiotic-rich foods (such as kimchi, sauerkraut, plain yogurt, and miso). Moreover, “the quality and structure of our fatty acids may be relevant as well: Increasing our intake of polyunsaturated fatty acids and avoiding processed fats like trans fats and hydrogenated oils may benefit our overall brain health.”

Dr. Naidoo recommends extra-virgin olive oil as a source of healthy fat. Its consumption is linked to lower incidence of AD by way of encouraging autophagy, which she calls “our own process of “cellular cleanup.’”

Dr. Naidoo believes that clinicians’ guidance to patients should “focus on healthy nutrition and other lifestyle practices, such as exercise, outdoor time, good sleep, and stress reduction.” 

Dr. Mills notes the importance of omega-3 fatty acids, such as docosahexaenoic acid (DHA) , for brain health. “DHA is a major lipid component of neuronal membranes,” she said. “Because of inefficiencies in metabolism with APOE4, people tend to metabolize more of the lipids on the membranes themselves, so they have higher lipid membrane turnover and a greater need to supplement. Supplementing particularly through diet, with foods such as fatty fish rich in omega-3, can help boost the levels to help keep neuronal membranes intact.”
 

What This Means for the Clinician

“At this point, we see all of these associations between lipids and dementia, but we haven’t worked out exactly what it means on the individual level for an individual patient,” said Dr. Mills. Certainly, the picture is complex, and the understanding is growing and shifting. “The clinical applications remain unclear.”

One potential clinical take-home is that clinicians might consider tracking lipid levels over time. “If you follow a patient and see an increase or decrease [in lipid levels], that can be informative.” Looking at ratios of lipids might be more useful than looking only at a change in a single measure. “If you see trends in a variety of measures that track with one another, it might be more of a sign that something is potentially wrong.” 

Whether the patient should first try a lifestyle intervention or might need medication is a “personalized clinical decision, depending on the individual, their risk factors, and how their levels are going,” said Dr. Mills. 

Dr. Mills, Dr. Hansen, and Dr. Naidoo declared no relevant financial relationships.

An influential panel is seeking an increase in Medicare’s 2025 payments for clinicians, adding to pressure on Congress to reconsider how the largest US purchaser of health services pays for office visits and related care of the nation’s older citizens and those with disabilities.

The Medicare Payment Advisory Commission (MedPAC) on Thursday voted unanimously in favor of a two-part recommendation on changes to the 2025 physician fee schedule:

• An increase in the base rate equal to half of the projected change in the Medicare Economic Index (MEI). Recent estimates have projected a 2.6% increase in MEI for 2025, which is intended to show how inflation affects the costs of running a medical practice.
• The creation of a safety-net add-on payment under the physician fee schedule to cover care of people with low incomes.

These recommendations echo the calls MedPAC made in a 2023 report to Congress. 

Lawmakers and the Centers for Medicare and Medicaid Services (CMS) rely on MedPAC’s work in deciding how much to pay for services. About 1.3 million clinicians bill Medicare for their work, including about 670,000 physicians.

Thursday’s MedPAC vote comes amid continuing uncertainty about how much the federal government will actually pay clinicians this year through the physician fee schedule.

There are serious efforts underway to undo cuts already demanded by previously passed federal law. In an email, Rep. Larry Buchson, MD, (R-IN) said he remains committed to “eliminating the full 3.37% cut this year while also working toward a permanent solution to halt the downward spiral of physician reimbursement.”

“The Medicare payment cut to physicians will impede patients’ access to care and further accelerate the current path toward consolidation, physician burnout, and closure of medical practices,” Buchson told this news organization. “It’s past time that Congress provides much needed and deserved stability for America’s doctors.”

Congress this month is attempting to complete overdue budget legislation needed to fund federal operations for fiscal 2024, which began October 1, 2023. The pending expiration of a short-term stopgap continuing resolution could provide a vehicle that could also carry legislation that would address the physician fee schedule.

In a Thursday statement, Jesse M. Ehrenfeld, MD, MPH, president of the American Medical Association, commended MedPAC for its recommendations and urged lawmakers to act.

“Long-term reforms from Congress are overdue to close the unsustainable gap between what Medicare pays physicians and the actual costs of delivering high-quality care,” Dr. Ehrenfeld said. “When adjusted for inflation in practice costs, Medicare physician pay declined 26% from 2001 to 2023.”
 

Continual Struggles

Congress has struggled for years in its attempts to set Medicare payments for office visits and other services covered by the physician fee schedule. A 1990s budget law set the stage for what proved to be untenable reductions in payment through the sustainable growth rate mechanism.

Between 2003 through April 2014, lawmakers passed “doc-fix” legislation 17 times to block the slated cuts, according to the Congressional Research Service. In 2015, Congress passed an intended overhaul of the physician fee schedule through the Medicare Access and CHIP Reauthorization Act (MACRA). As part of this law, Congress eliminated a base automatic inflation adjuster for the physician fee schedule.

In recent years, Congress has acted repeatedly to address MACRA’s mandates for flat base pay. MedPAC and members of both parties in Congress have called for a broad new look at how Medicare pays physicians. 

At Thursday’s meeting, MedPAC member Lawrence Casalino, MD, PhD, MPH, noted that the struggles to keep up with inflation and the “unpredictability of what the payment rates are going to be from year to year really do affect physician morale.”
