Parkinson’s Risk in Women and History of Migraine: New Data

Article Type
Changed
Wed, 09/11/2024 - 11:49

 

TOPLINE:

A history of migraine is not associated with an elevated risk for Parkinson’s disease (PD) in women, regardless of headache frequency or migraine subtype, a new study suggests.

METHODOLOGY:

  • Researchers analyzed data on 39,312 women health professionals aged ≥ 45 years and having no history of PD who enrolled in the Women’s Health Study between 1992 and 1995 and were followed until 2021.
  • At baseline, 7321 women (18.6%) had migraine.
  • The mean follow-up duration was 22 years.
  • The primary outcome was a self-reported, physician-confirmed diagnosis of PD.

TAKEAWAY:

  • During the study period, 685 women self-reported a diagnosis of PD.
  • Of these, 18.7% of reported cases were in women with any migraine and 81.3% in women without migraine.
  • No significant association was found between PD risk and a history of migraine, migraine subtypes (with or without aura), or migraine frequency.
  • Migraine was not associated with a higher risk for PD than that of nonmigraine headaches.

IN PRACTICE:

“These results are reassuring for women who have migraine, which itself causes many burdens, that they don’t have to worry about an increased risk of Parkinson’s disease in the future,” study author Tobias Kurth, Charité - Universitätsmedizin Berlin, Germany, said in a press release.

SOURCE:

The study was led by Ricarda S. Schulz, MSc, Charité - Universitätsmedizin Berlin. It was published online in Neurology.

LIMITATIONS:

The study’s findings may not be generalizable to other populations, such as men and non-White individuals. The self-reported data on migraine and PD may be subject to inaccuracies. PD is often not diagnosed until symptoms have reached an advanced stage, potentially leading to cases being underreported. Changes in the status and frequency of migraine over the study period were not accounted for, which may have affected the results.

DISCLOSURES:

The authors did not disclose any specific funding for this work. The Women’s Health Study was supported by the National Cancer Institute and National Heart, Lung, and Blood Institute. Two authors reported having financial ties outside this work. Full disclosures are available in the original article.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.

The Link Between Vision Impairment and Dementia in Older Adults

Article Type
Changed
Tue, 09/17/2024 - 10:48

 

TOPLINE:

Addressing vision impairments could help with dementia prevention, as vision impairment is linked to 19% of dementia cases in older adults.
 

METHODOLOGY:

  • Researchers conducted a cross-sectional analysis using data from the National Health and Aging Trends Study (NHATS).
  • The analysis included 2767 US adults aged 71 years or older (54.7% female and 45.3% male).
  • Vision impairments were defined using 2019 World Health Organization criteria. Near and distance vision impairments were defined as greater than 0.30 logMAR, and contrast sensitivity impairment was identified by scores below 1.55 logCS.
  • Dementia was classified using a standardized algorithm developed in NHATS, which incorporated a series of tests measuring cognition, memory and orientation, reports of Alzheimer’s disease, or a dementia diagnosis from the patient or a proxy, and an informant questionnaire (Ascertain Dementia-8 Dementia Screening Interview).
  • The study analyzed data from 2021, with the primary outcome being the population attributable fraction (PAF) of dementia from vision impairment.

TAKEAWAY:

  • The PAF of dementia associated with at least one vision impairment was 19% (95% CI, 8.2-29.7).
  • Impairment in contrast sensitivity had the highest PAF among all other vision issues, at 15% (95% CI, 6.6-23.6). This figure was higher than that for impairment of near acuity, at 9.7% (95% CI, 2.6-17.0), or distance acuity, at 4.9% (95% CI, 0.1-9.9).
  • The highest PAFs for dementia due to vision impairment was among participants aged 71-79 years (24.3%; 95% CI, 6.6-41.8), women (26.8%; 95% CI, 12.2-39.9), and non-Hispanic White participants (22.3%; 95% CI, 9.6-34.5).

IN PRACTICE:

“While not proving a cause-and-effect relationship, these findings support inclusion of multiple objective measures of vision impairments, including contrast sensitivity and visual acuity, to capture the total potential impact of addressing vision impairment on dementia,” study authors wrote.

SOURCE:

This study was led by Jason R. Smith, ScM, of the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health in Baltimore. It was published online in JAMA Ophthalmology.

LIMITATIONS:

The limited sample sizes for American Indian, Alaska Native, Asian, and Hispanic groups prevented researchers from calculating PAFs for these populations. The cross-sectional design prevented the researchers from examining the timing of vision impairment in relation to a diagnosis of dementia. The study did not explore links between other measures of vision and dementia. Those with early cognitive impairment may not have updated glasses, affecting visual performance. The findings from the study may not apply to institutionalized older adults.

DISCLOSURES:

Jennifer A. Deal, PhD, MHS, reported receiving personal fees from Frontiers in Epidemiology, Velux Stiftung, and Medical Education Speakers Network outside the submitted work. Nicholas S. Reed, AuD, PhD, reported receiving stock options from Neosensory outside the submitted work. No other disclosures were reported.

Why More Doctors Are Joining Unions

Article Type
Changed
Tue, 09/10/2024 - 12:16

 

With huge shifts over the past decade in the way doctors are employed — half of all doctors now work for a health system or large medical group — the idea of unionizing is not only being explored but gaining traction within the profession. In fact, 8% of the physician workforce (or 70,000 physicians) belong to a union, according to statistics gathered in 2022.

Exact numbers are hard to come by, and, interestingly, although the American Medical Association (AMA) “ supports the right of physicians to engage in collective bargaining,” the organization doesn’t track union membership among physicians, according to an AMA spokesperson. 
 

Forming a Union

One challenge is that forming a union is not only time-consuming but also difficult, owing to several barriers. For starters, the laws dictating unionization differ by state, and the rules governing unionization vary if a hospital is public or private. If there’s enough momentum from doctors leading unionization efforts, approval from hospital leaders is required before an official election can be requested from the National Labor Relations Board.

That said, for doctors who are in a union — the two most popular are the Union of American Physicians and Dentists and the Doctors Council branch of the Service Employees International Union (SEIU)—the benefits are immense, especially because union members can focus on what matters, such as providing the best patient care possible.

For a profession that historically has not been unionized, this year alone, nine medical residency programs at hospitals such as Stanford Health, Montefiore Medical Center, and the University of Pennsylvania, formed unions, reported WBUR in Boston.
 

Belonging Matters 

“When you build a relationship with your patients, it’s special, and that connection isn’t replaceable,” said Nicholas VenOsdel, MD, a pediatrician at Allina Health Primary Care in Hastings, Minnesota, and a union member of the Doctors Council. “However, a lot of us have felt like that hasn’t been respected as the climate of healthcare has changed so fast.”

In fact, autonomy over how much time doctors spend with patients is driving a lot of interest in unionization.

“We don’t necessarily have that autonomy now,” said Amber Higgins, MD, an emergency physician and an obstetrician at ChristianaCare, a hospital network in Newark, Delaware, and a member of the Doctors Council. “There are so many other demands, whether it’s billing, patient documentation, or other demands from the employer, and all of that takes time away from patient care.”

Another primary driver of physician unionization is the physician burnout epidemic. Physicians collectively complain that they spend more time on electronic health record documentation and bureaucratic administration. Yet if unions can improve these working conditions, the benefit to physicians and their patients would be a welcome change.

Union members are bullish and believe that having a cohesive voice will make a difference.

“We need to use our collective voices to get back to focusing on patient care instead of staring at a computer screen for 80% of the day,” Dr. Higgins told this news organization. “So much of medicine involves getting to the correct diagnosis, listening to patients, observing them, and building a relationship with them. We need time to build that.”

With corporate consolidation and a profit-driven mandate by healthcare systems, doctors are increasingly frustrated and feel that their voices haven’t been heard enough when it comes to issues like workplace safety, working hours, and benefits, said Stuart Bussey, MD, JD, a family practice physician and president of the Union of American Physicians and Dentists in Sacramento, California. 

However, he adds that urging doctors to join together to fight for a better working environment hasn’t been easy.

“Doctors are individualists, and they don’t know how to work in packs like hospital administrators do,” said Dr. Bussey. “They’re hard to organize, but I want them to understand that unless they join hands, sign petitions, and speak as one voice, they’re going to lose out on an amazing opportunity.”
 

 

 

Overcoming Misperceptions About Unions

One barrier to doctors getting involved is the sentiment that unions might do the opposite of what’s intended — that is, they might further reduce a doctor’s autonomy and work flexibility. Or there may be a perception that the drive to join a union is predicated on making more money. 

Though he’s now in a union, Dr. VenOsdel, who has been in a hospital-based practice for 7 years, admits that he initially felt very differently about unions than he does today.

“Even though I have family members in healthcare unions, I had a neutral to even slightly negative view of unions,” said Dr. VenOsdel. “It took me working directly with the Minnesota Nurses Association and the Doctors Council to learn the other side of the story.”

Armed with more information, he began lobbying for stricter rules about how his state’s large healthcare systems were closing hospitals and ending much-needed community services.

“I remember standing at the Capitol in Minnesota and telling one of the members that I once felt negatively about unions,” he added. “I realized then that I only knew what employers were telling me via such things as emails about strikes — that information was all being shared from the employers’ perspective.”

The other misperception is that unions only exist to argue against management, including against colleagues who are also part of the management structure, said Dr. Higgins.

“Some doctors perceive being in a union as ‘how can those same leaders also be in a union,’” she said. She feels that they currently don’t have leadership representing them that can help with such things as restructuring their support teams or getting them help with certain tasks. “That’s another way unions can help.” 
 

Social Justice Plays a Role

For Dr. VenOsdel, being part of a union has helped him return to what he calls the “art” of medicine.

“Philosophically, the union gave me an option for change in what felt like a hopeless situation,” he said. “It wasn’t just that I was tossing the keys to someone else and saying, ‘I can’t fix this.’ Instead, we’re taking the reins back and fixing things ourselves.”

Bussey argues that as the uneven balance between administrators and providers in many healthcare organizations grows, the time to consider forming a union is now.

“We’re in a $4 trillion medical industrial revolution,” he said. “Administrators and bureaucrats are multiplying 30-fold times vs providers, and most of that $4 trillion supports things that don’t contribute to the doctor-patient relationship.”

Furthermore, union proponents say that where a one-on-one relationship between doctor and patient once existed, that has now been “triangulated” to include administrators.

“We’ve lost power in every way,” Dr. Bussey said. “We have the degrees, the liability, and the knowledge — we should have more power to make our workplaces safer and better.”

Ultimately, for some unionized doctors, the very holding of a union card is rooted in supporting social justice issues.

“When doctors realize how powerful a tool a union can be for social justice and change, this will alter perceptions of unions within our profession,” Dr. VenOsdel said. “Our union helps give us a voice to stand up for other staff who aren’t unionized and, most importantly, to stand up for the patients who need us.”

“Philosophically, the union gave me an option for change in what felt like a hopeless situation,” he said. “It wasn’t just that I was tossing the keys to someone else and saying, ‘I can’t fix this.’ Instead, we’re taking the reins back and fixing things ourselves.”

Bussey argues that as the uneven balance between administrators and providers in many healthcare organizations grows, the time to consider forming a union is now.

“We’re in a $4 trillion medical industrial revolution,” he said. “Administrators and bureaucrats are multiplying 30-fold times vs providers, and most of that $4 trillion supports things that don’t contribute to the doctor-patient relationship.”

Furthermore, union proponents say that where a one-on-one relationship between doctor and patient once existed, that has now been “triangulated” to include administrators.

“We’ve lost power in every way,” Dr. Bussey said. “We have the degrees, the liability, and the knowledge — we should have more power to make our workplaces safer and better.”

Ultimately, for some unionized doctors, the very holding of a union card is rooted in supporting social justice issues.

“When doctors realize how powerful a tool a union can be for social justice and change, this will alter perceptions of unions within our profession,” Dr. VenOsdel said. “Our union helps give us a voice to stand up for other staff who aren’t unionized and, most importantly, to stand up for the patients who need us.”

With huge shifts over the past decade in the way doctors are employed — half of all doctors now work for a health system or large medical group — the idea of unionizing is not only being explored but gaining traction within the profession. In fact, 8% of the physician workforce (or 70,000 physicians) belong to a union, according to statistics gathered in 2022.

Exact numbers are hard to come by, and, interestingly, although the American Medical Association (AMA) “ supports the right of physicians to engage in collective bargaining,” the organization doesn’t track union membership among physicians, according to an AMA spokesperson. 
 

Forming a Union

One challenge is that forming a union is not only time-consuming but also difficult, owing to several barriers. For starters, the laws dictating unionization differ by state, and the rules governing unionization vary if a hospital is public or private. If there’s enough momentum from doctors leading unionization efforts, approval from hospital leaders is required before an official election can be requested from the National Labor Relations Board.

That said, for doctors who are in a union — the two most popular are the Union of American Physicians and Dentists and the Doctors Council branch of the Service Employees International Union (SEIU)—the benefits are immense, especially because union members can focus on what matters, such as providing the best patient care possible.

For a profession that historically has not been unionized, this year alone, nine medical residency programs at hospitals such as Stanford Health, Montefiore Medical Center, and the University of Pennsylvania, formed unions, reported WBUR in Boston.
 

Belonging Matters 

“When you build a relationship with your patients, it’s special, and that connection isn’t replaceable,” said Nicholas VenOsdel, MD, a pediatrician at Allina Health Primary Care in Hastings, Minnesota, and a union member of the Doctors Council. “However, a lot of us have felt like that hasn’t been respected as the climate of healthcare has changed so fast.”

In fact, autonomy over how much time doctors spend with patients is driving a lot of interest in unionization.

“We don’t necessarily have that autonomy now,” said Amber Higgins, MD, an emergency physician and an obstetrician at ChristianaCare, a hospital network in Newark, Delaware, and a member of the Doctors Council. “There are so many other demands, whether it’s billing, patient documentation, or other demands from the employer, and all of that takes time away from patient care.”

Another primary driver of physician unionization is the physician burnout epidemic. Physicians collectively complain that they spend more time on electronic health record documentation and bureaucratic administration. Yet if unions can improve these working conditions, the benefit to physicians and their patients would be a welcome change.

Union members are bullish and believe that having a cohesive voice will make a difference.

“We need to use our collective voices to get back to focusing on patient care instead of staring at a computer screen for 80% of the day,” Dr. Higgins told this news organization. “So much of medicine involves getting to the correct diagnosis, listening to patients, observing them, and building a relationship with them. We need time to build that.”

With corporate consolidation and a profit-driven mandate by healthcare systems, doctors are increasingly frustrated and feel that their voices haven’t been heard enough when it comes to issues like workplace safety, working hours, and benefits, said Stuart Bussey, MD, JD, a family practice physician and president of the Union of American Physicians and Dentists in Sacramento, California. 

However, he adds that urging doctors to join together to fight for a better working environment hasn’t been easy.

“Doctors are individualists, and they don’t know how to work in packs like hospital administrators do,” said Dr. Bussey. “They’re hard to organize, but I want them to understand that unless they join hands, sign petitions, and speak as one voice, they’re going to lose out on an amazing opportunity.”
 

 

 

Overcoming Misperceptions About Unions

One barrier to doctors getting involved is the sentiment that unions might do the opposite of what’s intended — that is, they might further reduce a doctor’s autonomy and work flexibility. Or there may be a perception that the drive to join a union is predicated on making more money. 

Though he’s now in a union, Dr. VenOsdel, who has been in a hospital-based practice for 7 years, admits that he initially felt very differently about unions than he does today.

“Even though I have family members in healthcare unions, I had a neutral to even slightly negative view of unions,” said Dr. VenOsdel. “It took me working directly with the Minnesota Nurses Association and the Doctors Council to learn the other side of the story.”

Armed with more information, he began lobbying for stricter rules about how his state’s large healthcare systems were closing hospitals and ending much-needed community services.

“I remember standing at the Capitol in Minnesota and telling one of the members that I once felt negatively about unions,” he added. “I realized then that I only knew what employers were telling me via such things as emails about strikes — that information was all being shared from the employers’ perspective.”

The other misperception is that unions only exist to argue against management, including against colleagues who are also part of the management structure, said Dr. Higgins.

“Some doctors perceive being in a union as ‘how can those same leaders also be in a union,’” she said. She feels that they currently don’t have leadership representing them that can help with such things as restructuring their support teams or getting them help with certain tasks. “That’s another way unions can help.” 
 

Social Justice Plays a Role

For Dr. VenOsdel, being part of a union has helped him return to what he calls the “art” of medicine.

“Philosophically, the union gave me an option for change in what felt like a hopeless situation,” he said. “It wasn’t just that I was tossing the keys to someone else and saying, ‘I can’t fix this.’ Instead, we’re taking the reins back and fixing things ourselves.”

Bussey argues that as the uneven balance between administrators and providers in many healthcare organizations grows, the time to consider forming a union is now.

“We’re in a $4 trillion medical industrial revolution,” he said. “Administrators and bureaucrats are multiplying 30-fold times vs providers, and most of that $4 trillion supports things that don’t contribute to the doctor-patient relationship.”

Furthermore, union proponents say that where a one-on-one relationship between doctor and patient once existed, that has now been “triangulated” to include administrators.

“We’ve lost power in every way,” Dr. Bussey said. “We have the degrees, the liability, and the knowledge — we should have more power to make our workplaces safer and better.”

FDA Rejects MDMA-AT for PTSD, but Lykos, Others, Vow to Push on

Article Type

Mon, 09/09/2024 - 15:02

 

The Food and Drug Administration’s (FDA) decision not to approve midomafetamine-assisted therapy (MDMA-AT) for posttraumatic stress disorder (PTSD) puts the therapy’s near-term future in doubt, but officials say the rejection may not knock it out of contention as an eventual therapeutic tool for a variety of conditions.

In August the agency declined to approve the drug with currently available study data and requested that the company conduct an additional phase 3 trial. The agency’s action had potentially devastating consequences for MDMA-AT’s sponsor, Lykos Therapeutics, and was a huge disappointment for researchers, clinicians, and patients who were optimistic that it would be a new option for a condition that affects 13-17 million Americans.

For now, no other company is poised to imminently seek FDA approval for MDMA.

Despite the setback, research into MDMA that combines different psychotherapeutic approaches continues. Currently, there are seven US studies actively recruiting participants, and another 13 are registered with an eye toward starting recruitment, as reported on ClinicalTrials.gov.

The lack of FDA approval “actually increases the opportunity now for us to do trials,” said Michael Ostacher, MD, professor of psychiatry and behavioral sciences at Stanford Medicine in California. Researchers won’t have to be sponsored by Lykos to get access to MDMA.

“There’s a lot of energy and interest in doing these studies,” he said in an interview, adding that philanthropic organizations and Veterans Affairs (VA) are contributing funds to support such studies.

The VA provided a statement saying that it “intends to gather rigorous scientific evidence on the potential efficacy and safety of psychedelic compounds when used in conjunction with psychotherapy.” It also noted that “these studies will be conducted under stringent safety protocols and will mark the first time since the 1960’s that VA is funding research on such compounds.”

Rachel Yehuda, PhD, director of the Center for Psychedelic Therapy Research at Icahn School of Medicine at Mount Sinai in New York City, said in an interview that the FDA rejection “raises questions about how to keep the work going.”

Without the FDA’s imprimatur, MDMA remains a schedule 1 drug, which means it has no valid medical use.

“It’s a lot more complicated and expensive to work with a scheduled compound than to work with a compound that has been approved,” Dr. Yehuda said.

Also, without Lykos or another drug company sponsor, investigators have to find an acceptable MDMA source on their own, said Dr. Yehuda, who was an investigator on a study in which Lykos provided MDMA but was not involved in study design, data collection, analysis, or manuscript preparation.
 

Lykos in Disarray

Within a week of the FDA’s decision, Lykos announced it was cutting its staff by 75% and that Rick Doblin, PhD, the founder and president of the Multidisciplinary Association for Psychedelic Studies (MAPS) that gave rise to Lykos, had resigned from the Lykos board.

A frequently controversial figure, Doblin has been attempting to legitimize MDMA as a therapy since the mid-1980s. He formed a public benefit corporation (PBC) in 2014 with an eye toward FDA approval. The PBC fully separated from MAPS in 2024 and became Lykos.

Although the FDA has left the door open to approval, Lykos has not released the agency’s complete response letter, so it’s not clear exactly what the FDA is seeking. In a statement, the company said it believes the issues “can be addressed with existing data, postapproval requirements, or through reference to the scientific literature.”

Lykos said in an email that it is working on “securing the meeting with the FDA” and that it “will work with the agency to determine what needs to be done to fulfill their requests.”

Soon after the FDA decision, Lykos was hit with another blow. The journal Psychopharmacology retracted an article that pooled six Lykos phase 2 studies, claiming the paper’s authors knew about unethical conduct before submission but did not inform the publisher.

Lykos said the issues could have been addressed through a correction and that it has filed a complaint with the Committee on Publication Ethics. It also noted that the misconduct at issue was reported to the FDA and Health Canada.

“However, we did not disclose the violations to the journal itself, an additional step we should have taken and regret not doing,” the company said. It added that the efficacy data in the paper were not part of the FDA submission.

Author Allison A. Feduccia, PhD, cofounder of Psychedelic Support, agreed with the retraction but disagreed with the wording. In a post on LinkedIn, she said she and other authors were not informed about the misconduct until years after the study’s submission.

Four authors — including Dr. Doblin — disagreed with the retraction.

Dr. Doblin said in a statement that he’d resigned from Lykos to escape the restrictions that came with being a fiduciary. “Now I can advocate and speak freely,” he said, adding that he could also return to his activist roots.

He predicted that Lykos would eventually gain FDA approval. But if Lykos can’t convince the agency, it have the necessary data already in hand; “potential FDA approval is now at least 2 years away, possibly more,” Dr. Doblin said in his statement.
 

Research Continues

Lykos is not the only company hoping to commercialize MDMA. Toronto-based Awakn Life Sciences has an MDMA preclinical development program for addiction. In addition, some companies are offering MDMA therapy through clinics, such as Numinus in Utah and Sunstone Therapies in Rockville, Maryland.

But Lykos was the closest to bringing a product to market. The company is still a sponsor of four MDMA-related clinical trials, three of which appear to be on hold. One study at the VA San Diego Healthcare System, San Diego, that is actively recruiting is an open-label trial to assess MDMA-AT in combination with brief Cognitive-Behavioral Conjoint Therapy for PTSD.

Those studies are among 13 US trials listed in ClinicalTrials.gov that have not yet begun recruiting and 7 that are actively recruiting.

Among them is a study of MDMA plus exposure therapy, funded by and conducted at Emory University in Atlanta. One of the Emory principal investigators, Barbara Rothbaum, MD, has also been named to a Lykos’ panel that would help ensure oversight of MDMA-AT post FDA approval.

Dr. Ostacher is an investigator in a study planned at VA Palo Alto Health Care System in California, that will compare MDMA-AT with cognitive processing therapy in veterans with severe PTSD. He said it will be open label in an effort to minimize expectation bias and issues with blinding — both problems that tripped up the Lykos application. Although placebo-controlled trials are the gold standard, it’s not ideal when “the purpose of the drug is for it to change how you see the world and yourself,” Dr. Ostacher said.

The study aims to see whether MDMA-AT is better than “a much shorter, less onerous, but quite evidence-based psychotherapy for PTSD,” he said.

The FDA’s decision is not the end of the road, said Dr. Ostacher. “Even though I think this makes for an obvious delay, I don’t think that it’s a permanent one,” he said.

Dr. Yehuda also said she is not ready to give up.

“We don’t plan on stopping — we plan on finding a way,” she said.

“In our experience, this is a very powerful approach that helps a lot of people that haven’t found help using other approaches, and when it’s in the hands of really trusted, experienced, ethical clinicians in a trusted environment, this could be a real game changer for people who have not been able to find belief by traditional methods,” she said.

Dr. Ostacher reported no relevant financial relationships. Dr. Yahuda is the principal investigator on clinical trials for the Center for Psychedelic Psychotherapy and Trauma Research that are sponsored by the Multidisciplinary Association for Psychedelic Studies and COMPASS Pathways.

Wait, a Health Worker Surplus? Workforce Report Projects Big Surprises

Article Type
Changed
Tue, 09/10/2024 - 09:26

A surprising new report by the Mercer consulting firm projects that the American healthcare workforce will face a small shortfall in 2028 — a shortage of less than 1% of all employees. The report even projects a surplus of tens of thousands of registered nurses and home health aides — and even a small surplus of physicians in some states.

Mercer’s projections are rosier than federal workforce projections, which paint a grimmer picture of impending shortages.

“The labor market is a little more stabilized right now, and most healthcare systems are seeing less turnover,” Dan Lezotte, PhD, a partner with Mercer, said in an interview. But he noted “critical shortages” are still expected in some areas.

Mercer last projected workforce numbers in a 2020-2021 report released during the height of the COVID-19 pandemic. Now, “the labor market is drastically different,” Dr. Lezotte said. Health workforce shortages and surpluses have long varied significantly by region across the country.

The report forecasts a small surplus of physicians in 2028 but not in states such as California, New York, and Texas. The upper Midwest states will largely see doctor surpluses while Southern states face shortages. Some states with general physician surpluses may still experience shortages of specialists.

A surplus of nearly 30,000 registered nurses is expected, but New York, New Jersey, and Connecticut are projected to have a combined shortage of 16,000 nurses.

Overall, the report projects a shortage of more than 100,000 healthcare workers nationally by 2028. That’s less than 1% of the entire healthcare workforce of 18.6 million expected by then.

The report also predicts a shortage of nurse practitioners, especially in California and New York, and a shortage of 73,000 nursing assistants, especially in California, New York, and Texas.

“Healthcare systems are having the most difficulty hiring and hanging on to those workers who are supposed to take up the load off physicians and nurses,” Dr. Lezotte said. “They’re competing not only with other healthcare systems but with other industries like Amazon warehouses or McDonald’s in California paying $20 an hour. Healthcare was a little slow to keep up with that. In a lot of healthcare systems, that’s their biggest headache right now.”

On the other hand, the report projects a national surplus of 48,000 home health/personal care aides.

That surprised Bianca K. Frogner, PhD, director of the Center for Health Workforce Studies at the University of Washington, Seattle.

“We are seeing increasing movement of investments toward moving patients out of skilled nursing facilities and keeping them in the home and community, which requires many more home health aides,” Dr. Frogner said. “Given such high turnover in this occupation, it’s hard to know if the surplus is really a surplus or if they will quickly be employed.”

Dr. Frogner receives grants and contracts from not-for-profit entities to investigate issues related to the health workforce.

Dr. Lezotte said the report’s findings are based on data from sources such as public and private databases and job postings. According to the report, “projections were made up to 2028 based on historical data up to 2023,” and “supply projections were derived using a linear autoregressive model based on historical supply within each occupation and geography.”

It’s not clear why some states like New York are expected to have huge shortages, but migration might be a factor, along with a lack of nearby nursing schools, Dr. Lezotte said.

As for shortages, Dr. Lezotte said healthcare systems will have to understand their local workforce situation and adapt. “They’ll need to be more proactive about their employee value proposition” via competitive pay and benefits Flexibility regarding scheduling is also important.

“They’re going to have to figure out how to up their game,” he said.

What about states with surpluses? They might be target-rich environments for states facing shortages, he said.
 

 

 

Positive Outlook Not Shared by Other Researchers

Other workforce projections conflict with Mercer’s, according to Jean Moore, DrPH, and Gaetano Forte, MS, director and assistant director of the Center for Health Workforce Studies, School of Public Health, University at Albany, New York.

The National Center for Health Workforce Analysis projects a 10% shortage of registered nurses and a 13% shortage of physicians in 2031. The agency didn’t make projections for home health aides because that workforce is in flux.

Why are Mercer’s projections so different? Dr. Lezotte said other projections assume that equity efforts will bring healthcare to everyone who needs it. The report assumes this won’t happen, he said. As a result, it expects there will be fewer patients who need to be served by workers.

Other projections expect a shortage of 300,000 registered nurses by 2035, Mr. Forte said. But the number of nurse practitioners in New York is growing quickly, Dr. Moore said.

Dr. Moore said it’s difficult to interpret Mercer’s findings because the company doesn’t provide enough information about its methodology.

“At some level, it’s not particularly useful regarding what the next steps are,” she said. “Projections should make you think about what you should do to change and improve, to create more of what you need.”

The Center for Health Workforce Studies at the University of Albany has provided consulting services to multiple companies that provide healthcare workforce projections. It has no relationship with Mercer.

A surprising new report by the Mercer consulting firm projects that the American healthcare workforce will face a small shortfall in 2028 — a shortage of less than 1% of all employees. The report even projects a surplus of tens of thousands of registered nurses and home health aides — and even a small surplus of physicians in some states.

Mercer’s projections are rosier than federal workforce projections, which paint a grimmer picture of impending shortages.

“The labor market is a little more stabilized right now, and most healthcare systems are seeing less turnover,” Dan Lezotte, PhD, a partner with Mercer, said in an interview. But he noted “critical shortages” are still expected in some areas.

Mercer last projected workforce numbers in a 2020-2021 report released during the height of the COVID-19 pandemic. Now, “the labor market is drastically different,” Dr. Lezotte said. Health workforce shortages and surpluses have long varied significantly by region across the country.

The report forecasts a small surplus of physicians in 2028 but not in states such as California, New York, and Texas. The upper Midwest states will largely see doctor surpluses while Southern states face shortages. Some states with general physician surpluses may still experience shortages of specialists.

A surplus of nearly 30,000 registered nurses is expected, but New York, New Jersey, and Connecticut are projected to have a combined shortage of 16,000 nurses.

Cell Phone Use Linked to Higher Heart Disease Risk

Article Type
Changed
Fri, 09/06/2024 - 15:38

Using a cell phone for at least one call per week is linked to a higher risk for cardiovascular disease (CVD), especially among smokers and patients with diabetes, according to a new UK Biobank analysis.

“We found that a poor sleep pattern, psychological distress, and neuroticism significantly mediated the positive association between weekly mobile phone usage time and the risk for incident CVD, with a mediating proportion of 5.11%, 11.50%, and 2.25%, respectively,” said principal investigator Xianhui Qin, MD, professor of nephrology at Southern Medical University, Guangzhou, China.

Poor sleep patterns and poor mental health could disrupt circadian rhythms and endocrine and metabolic functions, as well as increase inflammation, he explained.

In addition, chronic exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from cell phones could lead to oxidative stress and an inflammatory response. Combined with smoking and diabetes, this exposure “may have a synergistic effect in increasing CVD risk,” Dr. Qin suggested.

The study was published online in the Canadian Journal of Cardiology.
 

Risk Underestimated?

The researchers aimed to examine the association of regular cell phone use with incident CVD and explore the mediating effects of sleep and mental health using linked hospital and mortality records.

Their analysis included 444,027 participants (mean age, 56 years; 44% men) without a history of CVD from the UK Biobank. A total of 378,161 participants were regular cell phone users.

Regular cell phone use was defined as at least one call per week. Weekly use was self-reported as the average time of calls per week during the previous 3 months.

The primary outcome was incident CVD. Secondary outcomes were each component of CVD (ie, coronary heart disease, stroke, atrial fibrillation, and heart failure) and increased carotid intima media thickness (CIMT).

Compared with nonregular cell phone users, regular users were younger, had higher proportions of current smokers and urban residents, and had lower proportions of history of hypertension and diabetes. They also had higher income, Townsend deprivation index, and body mass index, and lower education levels.

During a median follow-up of 12.3 years, 56,181 participants developed incident CVD. Compared with nonregular cell phone users, regular users had a significantly higher risk for incident CVD (hazard ratio, 1.04) and increased CIMT (odds ratio, 1.11).

Among regular cell phone users, the duration of cell phone use and hands-free device/speakerphone use during calls was not significantly associated with incident CVD. Yet a significant and positive dose-response relationship was seen between weekly cell phone usage time and the risk for CVD. The positive association was stronger in current vs noncurrent smokers and people with vs without diabetes.

To different extents, sleep patterns (5.11%), psychologic distress (11.5%), and neuroticism (2.25%) mediated the relationship between weekly cell phone usage time and the risk for incident CVD.

“Our study suggests that despite the advantages of mobile phone use, we should also pay attention to the potential harm of mobile phone use to cardiovascular health,” Dr. Qin said. “Future studies to assess the risk-benefit balance will help promote mobile phone use patterns that are conducive to cardiovascular health.”

Meanwhile, he added, “We encourage measures to reduce time spent on mobile phones to promote the primary prevention of CVD. On the other hand, improving sleep and mental health status may help reduce the higher risk of CVD associated with mobile phone use.”

There are several limitations to the study in addition to its observational nature, which cannot show cause and effect. The questionnaires on cell phone use were restricted to phone calls; other use patterns of cell phones (eg, messaging, watching videos, and browsing the web) were not considered. Although the researchers adjusted for many potential confounders, unmeasured confounding bias (eg, the type of cell phone used and other sources of RF-EMF) cannot be eliminated.
 

 

 

Weak Link?

In a comment, Nicholas Grubic, MSc, a PhD student in epidemiology at the University of Toronto, Ontario, Canada, and coauthor of a related editorial, said, “I found it interesting that there was a connection observed between mobile phone use and CVD. However, it is crucial to understand that this link appeared to be much weaker compared with other well-known cardiovascular risk factors, such as smoking, diabetes, and high blood pressure. For now, mobile phone use should not be a major concern for most people.”

Nevertheless, clinicians should encourage patients to practice healthy habits around their screen time, he advised. “This could include limiting mobile phone use before bedtime and taking regular breaks to engage in activities that promote heart health, such as exercising or spending time outdoors.

“For the time being, we probably won’t see mobile phone use included in standard assessments for cardiovascular risk or as a focal point of cardiovascular health promotion initiatives,” he added. Instead, clinicians should “focus on established risk factors that have a stronger impact on patients’ cardiovascular health.”

Nieca Goldberg, MD, a clinical associate professor of medicine at NYU Grossman School of Medicine in New York City and American Heart Association volunteer expert, had a similar message. “You don’t have to go back to using a landline,” she said. “Instead, patients should be more mindful of how much phone use is taking away from their physical activity, keeping them from sleeping, and causing them stress.” Clinicians should also remember to counsel smokers on smoking cessation.

“It would be important for future studies to look at time spent on the phone and the type of activities patients are doing on their phones, such as social media, calls, texts, movies, or streaming TV shows,” she said. “It would be important to see how phone use is leading to a sedentary lifestyle” and what that means for a larger, more diverse population.

The study was supported by the National Key R&D Program, the National Natural Science Foundation of China, and the Outstanding Youth Development Scheme of Nanfang Hospital, Southern Medical University. Dr. Qin, Dr. Grubic, and Dr. Goldberg reported having no relevant financial relationships.

Brain Network Significantly Larger in People With Depression, Even in Childhood

Article Type
Changed
Fri, 09/06/2024 - 13:35

Researchers have discovered that a brain network involved in reward processing and attention to stimuli is markedly bigger in people with depression, remains stable over time, is unaffected by mood changes, and can be detected in children before onset of depression symptoms.

Using a novel brain-mapping technique, researchers found that the frontostriatal salience network was expanded nearly twofold in the brains of most individuals studied with depression compared with controls.

“This expansion in cortex was trait-like, meaning it was stable over time and did not change as symptoms changed over time,” said lead author Charles Lynch, PhD, assistant professor of neuroscience, Department of Psychiatry, Weill Cornell Medicine in New York.

It could also be detected in children who later developed depression, suggesting it may serve as a biomarker of depression risk. Investigators said the findings could aid in prevention and early detection of depression, as well as the development of more personalized treatment.

The study was published online in Nature.
 

Prewired for Depression?

Precision functional mapping is a relatively new approach to brain mapping in individuals that uses large amounts of fMRI data from hours of scans per person. The technique has been used to show differences in brain networks between and in healthy individuals but had not been used to study brain networks in people with depression.

“We leveraged our large longitudinal datasets — with many hours of functional MRI scanning per subject — to construct individual-specific maps of functional brain networks in each patient using precision functional mapping, instead of relying on group average,” Dr. Lynch said.

In the primary analysis of 141 adults with major depression and 37 healthy controls, the frontostriatal salience network — which is involved in reward processing and attention to internal and external stimuli — was markedly larger in these individuals with depression.

“This is one of the first times these kinds of personalized maps have been created in individuals with depression, and this is how we first observed of the salience network being larger in individuals with depression,” Dr. Lynch said.

In four of the six individuals, the salience network was expanded more than twofold, outside the range observed in all 37 healthy controls. On average, the salience network occupied 73% more of the cortical surface relative to the average in healthy controls.

The findings were replicated using independent samples of repeatedly sampled individuals with depression and in large-scale group average data.

The expansion of the salience network did not change over time and was unaffected by changes in mood state.

“These observations led us to propose that instead of driving changes in depressive symptoms over time, salience network expansion may be a stable marker of risk for developing depression,” the study team wrote.

An analysis of brain scans from 57 children who went on to develop depressive symptoms during adolescence and an equal number of children who did not develop depressive symptoms supports this theory.

On average, the salience network occupied roughly 36% more of cortex in the children with no current or previous symptoms of depression at the time of their fMRI scans but who subsequently developed clinically significant symptoms of depression, relative to children with no depressive symptoms at any study time point, the researchers found.
 

 

 

Immediate Clinical Impact?

Reached for comment, Shaheen Lakhan, MD, PhD, neurologist and researcher based in Miami, said this research “exemplifies the promising intersection of neurology and digital health, where advanced neuroimaging and data-driven approaches can transform mental health care into a more precise and individualized practice,” Dr. Lakhan said. “By identifying this brain network expansion, we’re unlocking new possibilities for precision medicine in mental health.”

Dr. Lakhan, who wasn’t involved in this research, said identifying the expansion of the frontostriatal salience network in individuals with depression opens new avenues for developing novel therapeutics.

“By targeting this network through neuromodulation techniques like deep brain stimulation, transcranial magnetic stimulation, and prescription digital therapeutics, treatments can be more precisely tailored to individual neurobiological profiles,” Dr. Lakhan said. “Additionally, this network expansion could serve as a biomarker for early detection, allowing for preventive strategies or personalized treatment plans, particularly for those at risk of developing depression.”

In addition, a greater understanding of the mechanisms driving salience network expansion offers potential for discovering new pharmacological targets, Dr. Lakhan noted.

“Drugs that modulate synaptic plasticity or network connectivity might be developed to reverse or mitigate these neural changes. The findings also support the use of longitudinal monitoring to predict and preempt symptom emergence, improving outcomes through timely intervention. This research paves the way for more personalized, precise, and proactive approaches in treating depression,” Dr. Lakhan concluded.

Also weighing in, Teddy Akiki, MD, with the Department of Psychiatry and Behavioral Sciences at Stanford Medicine in California, noted that the effect size of the frontostriatal salience network difference in depression is “remarkably larger than typically seen in neuroimaging studies of depression, which often describe subtle differences. The consistency across multiple datasets and across time at the individual level adds significant weight to these findings, suggesting that it is a trait marker rather than a state-dependent marker.”

“The observation that this expansion is present even before the onset of depressive symptoms in adolescence suggests its potential as a biomarker for depression risk,” Dr. Akiki said. “This approach could lead to earlier identification of at-risk individuals and potentially inform the development of targeted preventive interventions.”

He cautioned that it remains to be seen whether interventions targeting the salience network can effectively prevent or treat depression.

This research was supported in part by the National Institute of Mental Health, the National Institute on Drug Addiction, the Hope for Depression Research Foundation, and the Foundation for OCD Research. Dr. Lynch and a coauthor are listed as inventors for Cornell University patent applications on neuroimaging biomarkers for depression which are pending or in preparation.

Researchers have discovered that a brain network involved in reward processing and attention to stimuli is markedly bigger in people with depression, remains stable over time, is unaffected by mood changes, and can be detected in children before onset of depression symptoms.

Using a novel brain-mapping technique, researchers found that the frontostriatal salience network was expanded nearly twofold in the brains of most individuals studied with depression compared with controls.

“This expansion in cortex was trait-like, meaning it was stable over time and did not change as symptoms changed over time,” said lead author Charles Lynch, PhD, assistant professor of neuroscience, Department of Psychiatry, Weill Cornell Medicine in New York.

It could also be detected in children who later developed depression, suggesting it may serve as a biomarker of depression risk. Investigators said the findings could aid in prevention and early detection of depression, as well as the development of more personalized treatment.

The study was published online in Nature.
 

Prewired for Depression?

Precision functional mapping is a relatively new approach to brain mapping in individuals that uses large amounts of fMRI data from hours of scans per person. The technique has been used to show differences in brain networks between and in healthy individuals but had not been used to study brain networks in people with depression.

Promising Results With CBT App in Young Adults With Anxiety

Article Type
Changed
Fri, 09/06/2024 - 12:40

 

TOPLINE:

A self-guided mobile application for cognitive behavioral therapy (CBT) is associated with significant reductions in anxiety in young adults with anxiety disorders after 3 weeks, with continued improvement through week 12, a new randomized clinical trial shows.

METHODOLOGY:

  • The study included 59 adults aged 18-25 years (mean age, 23 years; 78% women) with anxiety disorders (56% with generalized anxiety disorder; 41% with social anxiety disorder).
  • Participants received a 6-week CBT program with a self-guided mobile application called Maya and were assigned to one of three incentive strategies to encourage engagement: Loss-framed (lose points for incomplete sessions), gain-framed (earn points for completed sessions), or gain-social support (gain points with added social support from a designated person).
  • The primary end point was change in anxiety at week 6, measured with the Hamilton Anxiety Rating Scale.
  • The researchers also evaluated change in anxiety at 3 and 12 weeks, change in anxiety sensitivity, social anxiety symptoms, and engagement and satisfaction with the app.

TAKEAWAY:

  • Anxiety decreased significantly from baseline at week 3, 6, and 12 (mean differences, −3.20, −5.64, and −5.67, respectively; all P < .001), with similar reductions in anxiety among the three incentive conditions.
  • Use of the CBT app was also associated with significant reductions in anxiety sensitivity and social anxiety symptoms over time, with moderate to large effect sizes.
  • A total of 98% of participants completed the 6-week assessment and 93% the 12-week follow-up. On average, the participants completed 10.8 of 12 sessions and 64% completed all sessions.
  • The participants reported high satisfaction with the app across all time points, with no significant differences based on time or incentive condition.

IN PRACTICE:

“We hear a lot about the negative impact of technology use on mental health in this age group,” senior study author Faith M. Gunning, PhD, said in a press release. “But the ubiquitous use of cell phones for information may provide a way of addressing anxiety for some people who, even if they have access to mental health providers, may not go. If the app helps reduce symptoms, they may then be able to take the next step of seeing a mental health professional when needed.”

SOURCE:

The study was led by Jennifer N. Bress, PhD, Department of Psychiatry, Weill Cornell Medicine, New York City. It was published online in JAMA Network Open.

LIMITATIONS:

This study lacked a control group, and the unbalanced allocation of participants to the three incentive groups due to the COVID-19 pandemic may have influenced the results. The study sample, which predominantly consisted of female and college-educated participants, may not have accurately represented the broader population of young adults with anxiety.

DISCLOSURES:

This study was funded by the NewYork-Presbyterian Center for Youth Mental Health, the Khoury Foundation, the Paul and Jenna Segal Family Foundation, the Saks Fifth Avenue Foundation, Mary and Jonathan Rather, Weill Cornell Medicine, the Pritzker Neuropsychiatric Disorders Research Consortium, and the National Institutes of Health. Some authors reported obtaining grants, receiving personal fees, serving on speaker’s bureaus, and having other ties with multiple pharmaceutical companies and institutions.

Nighttime Outdoor Light Pollution Linked to Alzheimer’s Risk

Article Type
Changed
Fri, 09/06/2024 - 12:54

Living in areas saturated with artificial outdoor light at night is associated with an increased risk for Alzheimer’s disease, a new national study suggested.

Analyses of state and county light pollution data and Medicare claims showed that areas with higher average nighttime light intensity had a greater prevalence of Alzheimer’s disease.

Among people aged 65 years or older, Alzheimer’s disease prevalence was more strongly associated with nightly light pollution exposure than with alcohol misuse, chronic kidney disease, depression, or obesity.

In those younger than 65 years, greater nighttime light intensity had a stronger association with Alzheimer’s disease prevalence than any other risk factor included in the study.

“The results are pretty striking when you do these comparisons and it’s true for people of all ages,” said Robin Voigt-Zuwala, PhD, lead author and director, Circadian Rhythm Research Laboratory, Rush University, Chicago, Illinois.

The study was published online in Frontiers of Neuroscience.
 

Shining a Light

Exposure to artificial outdoor light at night has been associated with adverse health effects such as sleep disruption, obesity, atherosclerosis, and cancer, but this is the first study to look specifically at Alzheimer’s disease, investigators noted.

Two recent studies reported higher risks for mild cognitive impairment among Chinese veterans and late-onset dementia among Italian residents living in areas with brighter outdoor light at night.

For this study, Dr. Voigt-Zuwala and colleagues examined the relationship between Alzheimer’s disease prevalence and average nighttime light intensity in the lower 48 states using data from Medicare Part A and B, the Centers for Disease Control and Prevention, and NASA satellite–acquired radiance data.

The data were averaged for the years 2012-2018 and states divided into five groups based on average nighttime light intensity.

The darkest states were Montana, Wyoming, South Dakota, Idaho, Maine, New Mexico, Vermont, Oregon, Utah, and Nevada. The brightest states were Indiana, Illinois, Florida, Ohio, Massachusetts, Connecticut, Maryland, Delaware, Rhode Island, and New Jersey.

Analysis of variance revealed a significant difference in Alzheimer’s disease prevalence between state groups (P < .0001). Multiple comparisons testing also showed that states with the lowest average nighttime light had significantly different Alzheimer’s disease prevalence than those with higher intensity.

The same positive relationship was observed when each year was assessed individually and at the county level, using data from 45 counties and the District of Columbia.
 

Strong Association

The investigators also found that state average nighttime light intensity is significantly associated with Alzheimer’s disease prevalence (P = .006). This effect was seen across all ages, sexes, and races except Asian Pacific Island, the latter possibly related to statistical power, the authors said.

When known or proposed risk factors for Alzheimer’s disease were added to the model, atrial fibrillation, diabetes, hyperlipidemia, hypertension, and stroke had a stronger association with Alzheimer’s disease than average nighttime light intensity.

Nighttime light intensity, however, was more strongly associated with Alzheimer’s disease prevalence than alcohol abuse, chronic kidney disease, depression, heart failure, and obesity.

Moreover, in people younger than 65 years, nighttime light pollution had a stronger association with Alzheimer’s disease prevalence than all other risk factors (P = .007).

The mechanism behind this increased vulnerability is unclear, but there may be an interplay between genetic susceptibility of an individual and how they respond to light, Dr. Voigt-Zuwala suggested.

APOE4 is the genotype most highly associated with Alzheimer’s disease risk, and maybe the people who have that genotype are just more sensitive to the effects of light exposure at night, more sensitive to circadian rhythm disruption,” she said.

The authors noted that additional research is needed but suggested light pollution may also influence Alzheimer’s disease through sleep disruption, which can promote inflammation, activate microglia and astrocytes, and negatively alter the clearance of amyloid beta, and by decreasing the levels of brain-derived neurotrophic factor.
 

 

 

Are We Measuring the Right Light?

“It’s a good article and it’s got a good message, but I have some caveats to that,” said George C. Brainard, PhD, director, Light Research Program, Thomas Jefferson University in Philadelphia, Pennsylvania, and a pioneer in the study of how light affects biology including breast cancer in night-shift workers.

The biggest caveat, and one acknowledged by the authors, is that the study didn’t measure indoor light exposure and relied instead on satellite imaging.

“They’re very striking images, but they may not be particularly relevant. And here’s why: People don’t live outdoors all night,” Dr. Brainard said.

Instead, people spend much of their time at night indoors where they’re exposed to lighting in the home and from smartphones, laptops, and television screens.

“It doesn’t invalidate their work. It’s an important advancement, an important observation,” Dr. Brainard said. “But the important thing really is to find out what is the population exposed to that triggers this response, and it’s probably indoor lighting related to the amount and physical characteristics of indoor lighting. It doesn’t mean outdoor lighting can’t play a role. It certainly can.”

Reached for comment, Erik Musiek, MD, PhD, a professor of neurology whose lab at Washington University School of Medicine in St. Louis, Missouri, has extensively studied circadian clock disruption and Alzheimer’s disease pathology in the brain, said the study provides a 10,000-foot view of the issue.

For example, the study was not designed to detect whether people living in high light pollution areas are actually experiencing more outdoor light at night and if risk factors such as air pollution and low socioeconomic status may correlate with these areas.

“Most of what we worry about is do people have lights on in the house, do they have their TV on, their screens up to their face late at night? This can’t tell us about that,” Dr. Musiek said. “But on the other hand, this kind of light exposure is something that public policy can affect.”

“It’s hard to control people’s personal habits nor should we probably, but we can control what types of bulbs you put into streetlights, how bright they are, and where you put lighting in a public place,” he added. “So I do think there’s value there.”

At least 19 states, the District of Columbia, and Puerto Rico have laws in place to reduce light pollution, with the majority doing so to promote energy conservation, public safety, aesthetic interests, or astronomical research, according to the National Conference of State Legislatures.

To respond to some of the limitations in this study, Dr. Voigt-Zuwala is writing a grant application for a new project to look at both indoor and outdoor light exposure on an individual level.

“This is what I’ve been wanting to study for a long time, and this study is just sort of the stepping stone, the proof of concept that this is something we need to be investigating,” she said.

Dr. Voigt-Zuwala reported RO1 and R24 grants from the National Institutes of Health (NIH), one coauthor reported an NIH R24 grant; another reported having no conflicts of interest. Dr. Brainard reported having no relevant conflicts of interest. Dr. Musiek reported research funding from Eisai Pharmaceuticals.

In those younger than 65 years, greater nighttime light intensity had a stronger association with Alzheimer’s disease prevalence than any other risk factor included in the study.

“The results are pretty striking when you do these comparisons and it’s true for people of all ages,” said Robin Voigt-Zuwala, PhD, lead author and director, Circadian Rhythm Research Laboratory, Rush University, Chicago, Illinois.

The study was published online in Frontiers of Neuroscience.
 

Shining a Light

Exposure to artificial outdoor light at night has been associated with adverse health effects such as sleep disruption, obesity, atherosclerosis, and cancer, but this is the first study to look specifically at Alzheimer’s disease, investigators noted.

Two recent studies reported higher risks for mild cognitive impairment among Chinese veterans and late-onset dementia among Italian residents living in areas with brighter outdoor light at night.

For this study, Dr. Voigt-Zuwala and colleagues examined the relationship between Alzheimer’s disease prevalence and average nighttime light intensity in the lower 48 states using data from Medicare Part A and B, the Centers for Disease Control and Prevention, and NASA satellite–acquired radiance data.

The data were averaged for the years 2012-2018 and states divided into five groups based on average nighttime light intensity.

The darkest states were Montana, Wyoming, South Dakota, Idaho, Maine, New Mexico, Vermont, Oregon, Utah, and Nevada. The brightest states were Indiana, Illinois, Florida, Ohio, Massachusetts, Connecticut, Maryland, Delaware, Rhode Island, and New Jersey.

Analysis of variance revealed a significant difference in Alzheimer’s disease prevalence between state groups (P < .0001). Multiple comparisons testing also showed that states with the lowest average nighttime light had significantly different Alzheimer’s disease prevalence than those with higher intensity.

The same positive relationship was observed when each year was assessed individually and at the county level, using data from 45 counties and the District of Columbia.
 

Strong Association

The investigators also found that state average nighttime light intensity is significantly associated with Alzheimer’s disease prevalence (P = .006). This effect was seen across all ages, sexes, and races except Asian Pacific Island, the latter possibly related to statistical power, the authors said.

When known or proposed risk factors for Alzheimer’s disease were added to the model, atrial fibrillation, diabetes, hyperlipidemia, hypertension, and stroke had a stronger association with Alzheimer’s disease than average nighttime light intensity.

Nighttime light intensity, however, was more strongly associated with Alzheimer’s disease prevalence than alcohol abuse, chronic kidney disease, depression, heart failure, and obesity.

Moreover, in people younger than 65 years, nighttime light pollution had a stronger association with Alzheimer’s disease prevalence than all other risk factors (P = .007).

The mechanism behind this increased vulnerability is unclear, but there may be an interplay between genetic susceptibility of an individual and how they respond to light, Dr. Voigt-Zuwala suggested.

APOE4 is the genotype most highly associated with Alzheimer’s disease risk, and maybe the people who have that genotype are just more sensitive to the effects of light exposure at night, more sensitive to circadian rhythm disruption,” she said.

The authors noted that additional research is needed but suggested light pollution may also influence Alzheimer’s disease through sleep disruption, which can promote inflammation, activate microglia and astrocytes, and negatively alter the clearance of amyloid beta, and by decreasing the levels of brain-derived neurotrophic factor.
 

 

 

Are We Measuring the Right Light?

“It’s a good article and it’s got a good message, but I have some caveats to that,” said George C. Brainard, PhD, director, Light Research Program, Thomas Jefferson University in Philadelphia, Pennsylvania, and a pioneer in the study of how light affects biology including breast cancer in night-shift workers.

The biggest caveat, and one acknowledged by the authors, is that the study didn’t measure indoor light exposure and relied instead on satellite imaging.

“They’re very striking images, but they may not be particularly relevant. And here’s why: People don’t live outdoors all night,” Dr. Brainard said.

Instead, people spend much of their time at night indoors where they’re exposed to lighting in the home and from smartphones, laptops, and television screens.

“It doesn’t invalidate their work. It’s an important advancement, an important observation,” Dr. Brainard said. “But the important thing really is to find out what is the population exposed to that triggers this response, and it’s probably indoor lighting related to the amount and physical characteristics of indoor lighting. It doesn’t mean outdoor lighting can’t play a role. It certainly can.”

Reached for comment, Erik Musiek, MD, PhD, a professor of neurology whose lab at Washington University School of Medicine in St. Louis, Missouri, has extensively studied circadian clock disruption and Alzheimer’s disease pathology in the brain, said the study provides a 10,000-foot view of the issue.

For example, the study was not designed to detect whether people living in high light pollution areas are actually experiencing more outdoor light at night and if risk factors such as air pollution and low socioeconomic status may correlate with these areas.

“Most of what we worry about is do people have lights on in the house, do they have their TV on, their screens up to their face late at night? This can’t tell us about that,” Dr. Musiek said. “But on the other hand, this kind of light exposure is something that public policy can affect.”

“It’s hard to control people’s personal habits nor should we probably, but we can control what types of bulbs you put into streetlights, how bright they are, and where you put lighting in a public place,” he added. “So I do think there’s value there.”

At least 19 states, the District of Columbia, and Puerto Rico have laws in place to reduce light pollution, with the majority doing so to promote energy conservation, public safety, aesthetic interests, or astronomical research, according to the National Conference of State Legislatures.

To respond to some of the limitations in this study, Dr. Voigt-Zuwala is writing a grant application for a new project to look at both indoor and outdoor light exposure on an individual level.

“This is what I’ve been wanting to study for a long time, and this study is just sort of the stepping stone, the proof of concept that this is something we need to be investigating,” she said.

Dr. Voigt-Zuwala reported RO1 and R24 grants from the National Institutes of Health (NIH), one coauthor reported an NIH R24 grant; another reported having no conflicts of interest. Dr. Brainard reported having no relevant conflicts of interest. Dr. Musiek reported research funding from Eisai Pharmaceuticals.

TOPLINE:

Hormone-modulating therapy for breast cancer may protect older women from Alzheimer’s disease and related dementias, although the protective effect varies by age and race, with the greatest benefit seen in younger Black women.

METHODOLOGY:

  • Hormone-modulating therapy is widely used to treat hormone receptor–positive breast cancer, but the cognitive effects of the treatment, including a potential link to dementia, remain unclear.
  • To investigate, researchers used the SEER-Medicare linked database to identify women aged 65 years or older with breast cancer who did and did not receive hormone-modulating therapy within 3 years following their diagnosis.
  • The researchers excluded women with preexisting Alzheimer’s disease/dementia diagnoses or those who had received hormone-modulating therapy before their breast cancer diagnosis.
  • Analyses were adjusted for demographic, sociocultural, and clinical variables, and subgroup analyses evaluated the impact of age, race, and type of hormone-modulating therapy on Alzheimer’s disease/dementia risk.

TAKEAWAY:

  • Among the 18,808 women included in the analysis, 66% received hormone-modulating therapy and 34% did not. During the mean follow-up of 12 years, 24% of hormone-modulating therapy users and 28% of nonusers developed Alzheimer’s disease/dementia.
  • Overall, hormone-modulating therapy use (vs nonuse) was associated with a significant 7% lower risk for Alzheimer’s disease/dementia (hazard ratio [HR], 0.93; P = .005), with notable age and racial differences.
  • Hormone-modulating therapy use was associated with a 24% lower risk for Alzheimer’s disease/dementia in Black women aged 65-74 years (HR, 0.76), but that protective effect decreased to 19% in Black women aged 75 years or older (HR, 0.81). White women aged 65-74 years who received hormone-modulating therapy (vs those who did not) had an 11% lower risk for Alzheimer’s disease/dementia (HR, 0.89), but the association disappeared among those aged 75 years or older (HR, 0.96; 95% CI, 0.90-1.02). Other races demonstrated no significant association between hormone-modulating therapy use and Alzheimer’s disease/dementia.
  • Overall, the use of an aromatase inhibitor or a selective estrogen receptor modulator was associated with a significantly lower risk for Alzheimer’s disease/dementia (HR, 0.93 and HR, 0.89, respectively).

IN PRACTICE:

Overall, the retrospective study found that “hormone therapy was associated with protection against [Alzheimer’s/dementia] in women aged 65 years or older with newly diagnosed breast cancer,” with the decrease in risk relatively greater for Black women and women younger than 75 years, the authors concluded.

“The results highlight the critical need for personalized breast cancer treatment plans that are tailored to the individual characteristics of each patient, particularly given the significantly higher likelihood (two to three times more) of Black women developing [Alzheimer’s/dementia], compared with their White counterparts,” the researchers added.
 

SOURCE:

The study, with first author Chao Cai, PhD, Department of Clinical Pharmacy and Outcomes Sciences, University of South Carolina, Columbia, was published online on July 16 in JAMA Network Open.

LIMITATIONS:

The study included only women aged 65 years or older, limiting generalizability to younger women. The dataset lacked genetic information and laboratory data related to dementia. The duration of hormone-modulating therapy use beyond 3 years and specific formulations were not assessed. Potential confounders such as variations in chemotherapy, radiation, and surgery were not fully addressed.

DISCLOSURES:

Support for the study was provided by the National Institutes of Health; Carolina Center on Alzheimer’s Disease and Minority Research pilot project; and the Dean’s Faculty Advancement Fund, University of Pittsburgh, Pennsylvania. The authors reported no relevant disclosures.
