More than two-thirds of patients with migraine also suffer from neck pain, a combination that’s linked to higher levels of various forms of disability, an international, prospective, cross-sectional study finds.

Of 51,969 respondents with headache over the past year, the 27.9% with migraine were more likely to have neck pain than those with non-migraine headache (68.3% vs 36.1%, respectively, P < .001), reported Richard B. Lipton, MD, professor of neurology at Albert Einstein College of Medicine, New York City, and colleagues in Headache.

Compared with other patients with migraine, those who also have neck pain have “greater disability, more psychiatric comorbidities, more allodynia, diminished quality of life, decreased work productivity, and reduced response to treatment,” Dr. Lipton said in an interview. “If patients don’t report [neck pain], it is probably worth asking about. And when patients have both migraine and neck pain, they may merit increased therapeutic attention.”

As Dr. Lipton noted, clinicians have long known that neck pain is common in migraine, although it’s been unclear how the two conditions are connected. “One possibility is that the neck pain is actually a manifestation of the migraine headache. Another possibility is that the neck pain is an independent factor unrelated to migraine headaches: Many people have migraine and cervical spine disease. And the third possibility is that neck pain may be an exacerbating factor, that cervical spine disease may make the migraine worse.”

Referred pain is a potential factor too, he said.
 

Assessing Migraine, Neck Pain, and Disability

The new study sought to better understand the role of neck pain in migraine, Dr. Lipton said.

For the CaMEO-I study, researchers surveyed 51,969 adults with headache via the Internet in Canada, France, Germany, Japan, United Kingdom, and the United States from 2021-2022. Most of the 37,477 patients with non-migraine headaches were considered to have tension headaches.

Among the 14,492 patients with migraine, demographics were statistically similar among those who had neck pain or didn’t have it (average age = 40.7 and 42.1, 68.4% and 72.5% female, and average BMIs = 26.0 and 26.4, respectively).

Among patients in the US, 71.4% of patients with migraine reported neck pain versus 35.9% of those with non-migraine headaches. In Canada, the numbers were 69.5% and 37.5%, respectively.

Among all patients with migraine, moderate-to-severe disability was more common among those with neck pain than those without neck pain (47.7% vs 28.9%, respectively, P < .001). Those with both migraine and neck pain had more symptom burden (P < .001), and 28.4% said neck pain was their most bothersome symptom. They also had a higher number of symptoms (P < .001).

Several conditions were more common among patients with migraine who reported neck pain versus those who didn’t (depression/anxiety, 40.2% vs 28.2%; anxiety, 41.2% vs 29.2%; and allodynia, 54.0% vs 36.6%, respectively, all P  <  0.001). Those with neck pain were also more likely to have “poor acute treatment optimization” (61.1% vs 53.3%, respectively, P < .001).

Researchers noted limitations such as the use of self-reported data, the potential for selection bias, limitations regarding survey questions, and an inability to determine causation.
 

Clinical Messages

The findings suggest that patients with both migraine and neck pain have greater activation of second-order neurons in the trigeminocervical complex, Dr. Lipton said.

He added that neck pain is often part of the migraine prodrome or the migraine attack itself, suggesting that it’s “part and parcel of the migraine attack.” However, neck pain may have another cause — such as degenerative disease of the neck — if it’s not directly connected to migraine, he added.

As for clinical messages from the study, “it’s quite likely that the neck pain is a primary manifestation of migraine. Migraine may well be the explanation in the absence of a reason to look further,” Dr. Lipton said.

If neck pain heralds a migraine, treating the prodrome with CGRP receptor antagonists (“gepants”) can be helpful, he said. He highlighted other preventive options include beta blockers, anti-epilepsy drugs, and monoclonal antibodies. There’s also anecdotal support for using botulinum toxin A in patients with chronic migraine and neck pain, he said.

In an interview, Mayo Clinic Arizona associate professor of neurology Rashmi B. Halker Singh, MD, who’s familiar with the study but did not take part in it, praised the research. The findings “help us to better understand the impact of living with neck pain if you are somebody with migraine,” she said. “It alerts us that we need to be more aggressive in how we manage that in patients.”

The study also emphasizes the importance of preventive medication in appropriate patients with migraine, especially those with neck pain who may be living with greater disability, she said. “About 13% of people with migraine are on a preventive medication, but about 40% are eligible. That’s an area where we have a big gap.”

Dr. Halker Singh added that non-medication strategies such as acupuncture and physical therapy can be helpful.

AbbVie funded the study. Dr. Lipton reports support for the study from AbbVie; research support paid to his institution from the Czap Foundation, National Headache Foundation, National Institutes of Health, S&L Marx Foundation, and US Food and Drug Administration; and personal fees from AbbVie/Allergan, American Academy of Neurology, American Headache Society, Amgen, Biohaven, Biovision, Boston, Dr. Reddy’s (Promius), electroCore, Eli Lilly, GlaxoSmithKline, Grifols, Lundbeck (Alder), Merck, Pernix, Pfizer, Teva, Vector, and Vedanta Research. He holds stock/options in Axon, Biohaven, CoolTech, and Manistee. Other authors report various disclosures.

Mount Sinai Health System in New York City is forcing part-time physicians to sign employment contracts that violate their labor rights, according to a June 2024 complaint by the National Labor Relations Board (NLRB). 

The complaint stems from no-poaching and confidentiality clauses in the agreements required as a condition of employment, NLRB officials alleged.

The contracts state that, for 1 year following termination, part-time physicians may not recruit, solicit, or induce to terminate the employment of any hospital system employee or independent contractor, according to a copy of the terms included in NLRB’s June 18 complaint. 

By requiring the agreements, NLRB officials claimed, Mount Sinai is “interfering with, restraining, and coercing employees” in violation of the National Labor Relations Act. The health system’s “unfair labor practices” affects commerce as outlined under the law, according to the NLRB. The Act bans employers from burdening or obstructing commerce or the free flow of commerce.

Mount Sinai did not respond to requests for comment.

The NLRB’s complaint follows a landmark decision by the Federal Trade Commission (FTC) to ban noncompete agreements nationwide. In April 2024, the FTC voted to prohibit noncompetes indefinitely in an effort to protect workers.

“Noncompete clauses keep wages low, suppress new ideas, and rob the American economy of dynamism, including from the more than 8500 new startups that would be created a year once noncompetes are banned,” FTC Chair Lina M. Khan said in a statement. “The FTC’s final rule to ban noncompetes will ensure Americans have the freedom to pursue a new job, start a new business, or bring a new idea to market.”

Business groups and agencies have since sued to challenge against the ban, including the Chamber of Commerce. The Chamber and other business groups argue that noncompete agreements are important for companies to protect trade secrets, shield recruiting investments, and hide confidential information. The lawsuits are ongoing. 
 

A Physician Blows the Whistle

An anonymous physician first alerted the NLRB to the contract language in November 2023. The doctor was required the sign the hospital system’s agreement for part-time physicians. The complaint does not say if the employee is still employed by the hospital system. 

To remedy the unfair labor practices alleged, the NLRB seeks an order requiring the health system to rescind the contract language, stop any actions against current or former employees to enforce the provisions, and make whole any employees who suffered financial losses related to the contract terms. 

The allegation against Mount Sinai is among a rising number of grievances filed with the NLRB that claim unfair labor practices. During the first 6 months of fiscal year 2024, unfair labor practice charges filed across the NLRB’s field offices increased 7% — from 9612 in 2023 to 10,278 in 2024, according to a news release. 

NLRB, meanwhile has been cracking down on anticompetitive labor practices and confidentiality provisions that prevent employees from speaking out. 

In a February 2023 decision for instance, NLRB ruled that an employer violates the National Labor Relations Act by offering severance agreements to workers that include restrictive confidentiality and nondisparagement terms. In 2022, the NLRB and the Federal Trade Commission forged a partnership to more widely combat unfair, anticompetitive, and deceptive business practices. 

“Noncompete provisions reasonably tend to chill employees in the exercise of Section 7 rights when the provisions could reasonably be construed by employees to deny them the ability to quit or change jobs by cutting off their access to other employment opportunities that they are qualified for,” NLRB General Counsel Jennifer Abruzzo said in a 2023 release. 

Ms. Abruzzo stressed in a memo that NLR Act is committed to an interagency approach to restrictions on the exercise of employee rights, “including limits to workers’ job mobility, information sharing, and referrals to other agencies.” 

Mount Sinai Health System must respond to the NLRB’s complaint by July 16, and an administrative law judge is scheduled to hear the case on September 24.

Patients with atrial fibrillation who discontinued anticoagulation (OAC) therapy after an ischemic stroke faced double the risk of a recurrent stroke within 1 year compared with counterparts who didn’t stop the drugs, a new Danish nationwide cohort study finds.

Among 8,119 patients aged 50 years and older (54.1% male, mean age 78.4), 4.3% had a recurrent stroke within 1 year following discharge for the initial stroke, reported David Gaist, PhD, of Odense University Hospital, Odense, Denmark, and colleagues in JAMA Neurology.

An adjusted analysis found that those who stopped therapy were more than twice as likely to experience another stroke over a mean 2.9 years (13.4% vs 6.8%, adjusted odds ratio [aOR] = 2.13; 95% confidence interval [CI], 1.57-2.89).

The findings highlight the preventive power of OAC therapy, Dr. Gaist said in an interview, and point to the importance of counseling patients about the benefits of the drugs. “Clinicians can provide balanced information on the pros and cons of discontinuing oral anticoagulants as well as lay out plans on when to restart the medication,” he said.

The researchers launched the study “to provide data on how often recurrent ischemic strokes occur in a large, unselected cohort of patients with atrial fibrillation who had a stroke and started or restarted oral anticoagulants, a situation mirroring what we see in our everyday lives as clinicians,” Dr. Gaist said. “We also wanted to see if patients with breakthrough strokes had particular characteristics compared with patients who did not have a recurrent stroke. Finally, we wanted to quantify a very simple cause of breakthrough stroke by answering the following question: How many of these patients had stopped taking their oral anticoagulant?”
 

A Large, Unselected Patient Cohort

Dr. Gaist and colleagues tracked 8,119 patients with ischemic stroke and atrial fibrillation who started or restarted OAC therapy within 30 days following their discharge between 2014 and 2021. Patients either had atrial fibrillation before their stroke or developed it afterward.

Eighty-one percent of patients had hypertension, 19.7% had diabetes, and 27.3% had ischemic heart disease; 35.3% had never smoked and smoking information was missing for 15.9%. Race/ethnicity information was not provided.

Patients were followed for an average of 2.9 years until 2022, and all were alive at least 30 days after discharge. During that time, 663 patients had a recurrent ischemic stroke (4.3%), of whom 80.4% were on OAC therapy. The percentage who had stroke at 2 years rose to 6.5%.

While the researchers thought the number of strokes was high, Dr. Gaist said, this isn’t a sign that the drugs aren’t working. “Oral anticoagulant use in secondary prevention in atrial fibrillation is guideline-supported as it has been proven to reduce the risk of stroke by roughly two thirds.”

Of study participants at baseline, 37.9% took oral anticoagulants, 23.5% took direct oral anticoagulants (DOACs; dabigatran, rivaroxaban, apixaban, and edoxaban), and 15.1% took vitamin K antagonists. In a nested case-control analysis of 663 cases (58.7% men, mean age 80.1) matched to 2,652 controls, at admission for ischemic stroke, 80.4% were on OAC therapy, and 8%-11% of patients stopped OAC therapy after their strokes, the researchers reported.

Patients who stopped OAC therapy had more severe strokes than those who didn’t at 7 days (median recurrent ischemic stroke Scandinavian Stroke Scale [SSS] score = 40.0 vs 46.0, respectively; aOR = 2.10; 95% CI, 1.31-3.36). Those who stopped OAC therapy also had higher mortality rates at 7 days (11.2% vs 3.9%, respectively) and 30 days (28.1% vs 10.9%, respectively).

It’s not clear why some patients discontinued OAC therapy. “We looked for evidence of serious bleeding or surgical procedures around the time of anticoagulant discontinuation but found this only to be the case in roughly 10% of these patients,” Dr. Gaist said.

He added that the study probably “underestimates the issue of anticoagulant discontinuation, particularly for DOACs, where a shorter half-life compared with warfarin means that even a short drug-break of a few days puts the patient at increased risk of stroke.”

The authors noted study limitations, including the lack of data on actual medication usage, alcohol usage, stroke etiology, lesion location, and socioeconomic status. And, they wrote, the study population is mostly of European origin.
 

No Surprises

Steven R. Messe, MD, professor of neurology at the Hospital of the University of Pennsylvania, Philadelphia, who didn’t take part in the study but is familiar with its findings, said in an interview that the study is a “well-done analysis.”

The findings are not surprising, he said. “The overall risk of stroke recurrence was 4.3% at 1 year while the mortality rate was higher at 15.4%. Given that the median CHA₂DS₂-VASc score was 4 and the average age was 79, the stroke recurrence rate and mortality rate are in line with prior studies.”

In regard to the power of OAC therapy to prevent recurrent strokes, Dr. Messe noted that patients may not be adhering to prescribed regimens. Also, “while DOACs are clearly safer that vitamin K–dependent anticoagulants, the medications are generally not dose adjusted. It is possible that adjusting the dose based on measured anti-Xa levels to insure therapeutic anticoagulant effects may reduce the stroke risk further.”

He added that “most of these patients with prior stroke and atrial fibrillation are vasculopathic and at risk of additional strokes due to other mechanisms such as small vessel or large vessel disease.”

In the big picture, the study “confirms again that anticoagulation should be prescribed to all patients with atrial fibrillation and prior stroke, unless there is a strong bleeding risk contraindication,” Dr. Messe said. These patients are clearly at high risk of stroke recurrence and mortality, and all risk factors should be aggressively managed.”

Researchers are exploring other options, he said. “For example, there are studies of factor XI inhibitors that could be added to a DOAC for additional reductions in ischemic stroke. In addition, in patients undergoing cardiac surgery, the randomized trial LAOS III demonstrated that surgical left atrial occlusion in addition to anticoagulation may provide additional stroke prevention.”

Dr. Gaist disclosed personal fees from Pfizer and Bristol Myers Squibb, and grants from Bayer. Several other authors reported various relationships with industry. Dr. Messe has no disclosures.
 

Patients with atrial fibrillation who discontinued anticoagulation (OAC) therapy after an ischemic stroke faced double the risk of a recurrent stroke within 1 year compared with counterparts who didn’t stop the drugs, a new Danish nationwide cohort study finds.

Among 8,119 patients aged 50 years and older (54.1% male, mean age 78.4), 4.3% had a recurrent stroke within 1 year following discharge for the initial stroke, reported David Gaist, PhD, of Odense University Hospital, Odense, Denmark, and colleagues in JAMA Neurology.

An adjusted analysis found that those who stopped therapy were more than twice as likely to experience another stroke over a mean 2.9 years (13.4% vs 6.8%, adjusted odds ratio [aOR] = 2.13; 95% confidence interval [CI], 1.57-2.89).

The findings highlight the preventive power of OAC therapy, Dr. Gaist said in an interview, and point to the importance of counseling patients about the benefits of the drugs. “Clinicians can provide balanced information on the pros and cons of discontinuing oral anticoagulants as well as lay out plans on when to restart the medication,” he said.

The researchers launched the study “to provide data on how often recurrent ischemic strokes occur in a large, unselected cohort of patients with atrial fibrillation who had a stroke and started or restarted oral anticoagulants, a situation mirroring what we see in our everyday lives as clinicians,” Dr. Gaist said. “We also wanted to see if patients with breakthrough strokes had particular characteristics compared with patients who did not have a recurrent stroke. Finally, we wanted to quantify a very simple cause of breakthrough stroke by answering the following question: How many of these patients had stopped taking their oral anticoagulant?”
 

A Large, Unselected Patient Cohort

Dr. Gaist and colleagues tracked 8,119 patients with ischemic stroke and atrial fibrillation who started or restarted OAC therapy within 30 days following their discharge between 2014 and 2021. Patients either had atrial fibrillation before their stroke or developed it afterward.

Eighty-one percent of patients had hypertension, 19.7% had diabetes, and 27.3% had ischemic heart disease; 35.3% had never smoked and smoking information was missing for 15.9%. Race/ethnicity information was not provided.

Patients were followed for an average of 2.9 years until 2022, and all were alive at least 30 days after discharge. During that time, 663 patients had a recurrent ischemic stroke (4.3%), of whom 80.4% were on OAC therapy. The percentage who had stroke at 2 years rose to 6.5%.

While the researchers thought the number of strokes was high, Dr. Gaist said, this isn’t a sign that the drugs aren’t working. “Oral anticoagulant use in secondary prevention in atrial fibrillation is guideline-supported as it has been proven to reduce the risk of stroke by roughly two thirds.”

Of study participants at baseline, 37.9% took oral anticoagulants, 23.5% took direct oral anticoagulants (DOACs; dabigatran, rivaroxaban, apixaban, and edoxaban), and 15.1% took vitamin K antagonists. In a nested case-control analysis of 663 cases (58.7% men, mean age 80.1) matched to 2,652 controls, at admission for ischemic stroke, 80.4% were on OAC therapy, and 8%-11% of patients stopped OAC therapy after their strokes, the researchers reported.

Patients who stopped OAC therapy had more severe strokes than those who didn’t at 7 days (median recurrent ischemic stroke Scandinavian Stroke Scale [SSS] score = 40.0 vs 46.0, respectively; aOR = 2.10; 95% CI, 1.31-3.36). Those who stopped OAC therapy also had higher mortality rates at 7 days (11.2% vs 3.9%, respectively) and 30 days (28.1% vs 10.9%, respectively).

TOPLINE:

Compared with the general population, patients with urticaria had a 49% higher risk of developing cancer in the first year following diagnosis, which decreased to 6% in subsequent years, in a cohort study using Danish healthcare databases.

METHODOLOGY:

• Researchers conducted a retrospective cohort study using data from Danish healthcare registries and compared the incident cancer risk between patients with urticaria and the risk in the general population.
• They identified 87,507 patients (58% women) with a primary or secondary first-time hospital outpatient clinic, emergency room, or inpatient diagnosis of urticaria between 1980 and 2022, who were followed for a median of 10.1 years.
• Incident cancers, including nonmelanoma skin cancer, were identified using the Danish Cancer Registry and classified by the extent of spread at the time of diagnosis.
• This study computed the absolute cancer risk within the first year of an urticaria diagnosis and standardized incidence ratios (SIRs), with 95% CIs standardized to Danish national cancer rates.

TAKEAWAY:

• For the first year of follow-up, the absolute risk for all cancer types was 0.7%, and it was 29.5% for subsequent years. The overall SIR for all types of cancer was 1.09 (95% CI, 1.06-1.11), which was based on 7788 observed cancer cases compared with 7161 cases expected over the entire follow-up period.
• Within the first year of follow-up, 588 patients with urticaria were diagnosed with cancer, for an SIR of 1.49 (95% CI, 1.38-1.62) for all cancer types.
• After the first year, the SIR for all cancer sites decreased and stabilized at 1.06 (95% CI, 1.04-1.09), with 7200 observed cancer cases.
• The risk was highest for hematological cancers in the first year, particularly Hodgkin lymphoma (SIR, 5.35; 95% CI, 2.56-9.85).

IN PRACTICE:

“Our study suggests that urticaria may be a marker of occult cancer and that it is associated with a slightly increased long-term cancer risk,” the authors wrote.

SOURCE:

The study was led by Sissel B.T. Sørensen, departments of dermatology and rheumatology, Aarhus University Hospital, Aarhus, Denmark. It was published online on June 27, 2024, in the British Journal of Dermatology.

LIMITATIONS:

The study is limited by its observational design and reliance on registry data, which may be subject to misclassification or incomplete information. In addition, the study could not assess individual patient factors such as lifestyle or genetic predispositions that may influence cancer risk, and the results may not be generalizable to other populations. Finally, the exact biologic mechanisms linking urticaria and cancer remain unclear, warranting further investigation.

DISCLOSURES:

The study did not receive any funding. The authors reported that they had no relevant conflicts of interest.

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

Specifically, the lack of electronic case reporting in place during the pandemic — where diagnoses are documented in the record and then immediately sent to the public health system — led to reports that were delayed, not made, or had missing or incomplete information, such as patients’ race and ethnicity or other health conditions, Ms. Hamilton said. 

Incomplete or missing data hampered the ability of public health officials and researchers to understand how the virus might affect different patients.

“If you had a chronic condition like cancer, you were less likely to have a positive outcome with COVID,” Ms. Hamilton said. “But because electronic case reporting was not in place, we didn’t get some of those additional pieces of information. We didn’t have people’s underlying oncology status to then say, ‘Here are individuals with these types of characteristics, and these are the things that happen if they also have a cancer.’” 

Slow, but Steady, Improvements

Efforts at the state and federal levels have targeted improved health information exchange, but progress takes time, Dr. Adler-Milstein said.

Most states have some form of health information exchange, such as statewide exchanges, regional health information organizations, or clinical data registries. Maryland is often held up as a notable example for its health information exchange, Dr. Adler-Milstein noted.

According to Maryland law, all hospitals under the jurisdiction of the Maryland Health Care Commission are required to electronically connect to the state-designated health information exchange. In 2012, Maryland became the first state to connect all its 46 acute care hospitals in the sharing of real-time data. 

The Health Information Technology for Economic and Clinical Health (HITECH) Act provided federal-enhanced Medicaid matching funds to states through 2021 to support efforts to advance electronic exchange. Nearly all states used these funds, and most have identified other sources to sustain the efforts, according to a recent US Government Accountability Office (GAO) report. However, GAO found that small and rural providers are less likely to have the financial and technological resources to participate in or maintain electronic exchange capabilities.

Nationally, several recent initiatives have targeted health data interoperability, including for cancer care. The Centers for Disease Control and Prevention’s Data Modernization Initiative is a multiyear, multi–billion-dollar effort to improve data sharing across the federal and state public health landscape. 

Meanwhile, in March 2024, the Biden-Harris administration launched United States Core Data for Interoperability Plus Cancer. The program will define a recommended minimum set of cancer-related data to be included in a patient’s EHR to enhance data exchange for research and clinical care. 

EHR vendors are also key to improving the landscape, said Dr. Adler-Milstein. Vendors such as Epic have developed strong sharing capabilities for transmitting health information from site to site, but of course, that only helps if providers have Epic, she said. 

“That’s where these national frameworks should help, because we don’t want it to break down by what EHR vendor you have,” she said. “It’s a patchwork. You can go to some places and hear success stories because they have Epic or a state health information exchange, but it’s very heterogeneous. In some places, they have nothing and are using a fax machine.”

Mr. Havasy believes fax machines will ultimately go extinct, particularly as a younger, more digitally savvy generation enters the healthcare workforce. He also foresees that the growing use of artificial intelligence will help eradicate the outdated technology. 

But, Ms. Hamilton noted, “unless we have consistent, ongoing, sustained funding, it is very hard to move off [an older] technology that can work. That’s one of the biggest barriers.” 

“Public health is about protecting the lives of every single person everywhere,” Ms. Hamilton said, “but when we don’t have the data that comes into the system, we can’t achieve our mission.”

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

Specifically, the lack of electronic case reporting in place during the pandemic — where diagnoses are documented in the record and then immediately sent to the public health system — led to reports that were delayed, not made, or had missing or incomplete information, such as patients’ race and ethnicity or other health conditions, Ms. Hamilton said. 

Incomplete or missing data hampered the ability of public health officials and researchers to understand how the virus might affect different patients.

“If you had a chronic condition like cancer, you were less likely to have a positive outcome with COVID,” Ms. Hamilton said. “But because electronic case reporting was not in place, we didn’t get some of those additional pieces of information. We didn’t have people’s underlying oncology status to then say, ‘Here are individuals with these types of characteristics, and these are the things that happen if they also have a cancer.’”

Efforts at the state and federal levels have targeted improved health information exchange, but progress takes time, Dr. Adler-Milstein said.

Results from the latest survey by the National Comprehensive Cancer Network (NCCN) showed that numerous critical systemic anticancer therapies, primarily generic drugs, are currently in shortage.

Nearly 90% of the 28 NCCN member centers who responded to the survey, conducted between May 28 and June 11, said they were experiencing a shortage of at least one drug.

“Many drugs that are currently in shortage form the backbones of effective multiagent regimens across both curative and palliative treatment settings,” NCCN’s CEO Crystal S. Denlinger, MD, said in an interview.

The good news is that carboplatin and cisplatin shortages have fallen dramatically since 2023. At the peak of the shortage in 2023, 93% of centers surveyed reported experiencing a shortage of carboplatin and 70% were experiencing a shortage of cisplatin, whereas in 2024, only 11% reported a carboplatin shortage and 7% reported a cisplatin shortage.

“Thankfully, the shortages for carboplatin and cisplatin are mostly resolved at this time,” Dr. Denlinger said.

However, all three NCCN surveys conducted in the past year, including the most recent one, have found shortages of various chemotherapies and supportive care medications, which suggests this is an ongoing issue affecting a significant spectrum of generic drugs.

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”

Individuals with anxiety have at least a twofold higher risk of developing Parkinson’s disease than those without anxiety, new research suggested.

Investigators drew on 10-year data from primary care registry to compare almost 110,000 patients who developed anxiety after the age of 50 years with close to 900,000 matched controls without anxiety.

After adjusting for a variety of sociodemographic, lifestyle, psychiatric, and neurological factors, they found that the risk of developing Parkinson’s disease was double in those with anxiety, compared with controls.

“Anxiety is known to be a feature of the early stages of Parkinson’s disease, but prior to our study, the prospective risk of Parkinson’s in those over the age of 50 with new-onset anxiety was unknown,” colead author Juan Bazo Alvarez, a senior research fellow in the Division of Epidemiology and Health at University College London, London, England, said in a news release.

The study was published online in the British Journal of General Practice.

The presence of anxiety is increased in prodromal Parkinson’s disease, but the prospective risk for Parkinson’s disease in those aged 50 years or older with new-onset anxiety was largely unknown.

Investigators analyzed data from a large UK primary care dataset that includes all people aged between 50 and 99 years who were registered with a participating practice from Jan. 1, 2008, to Dec. 31, 2018.

They identified 109,435 people (35% men) with more than one anxiety record in the database but no previous record of anxiety for 1 year or more and 878,256 people (37% men) with no history of anxiety (control group).

Features of Parkinson’s disease such as sleep problems, depression, tremor, and impaired balance were then tracked from the point of the anxiety diagnosis until 1 year before the Parkinson’s disease diagnosis.

Among those with anxiety, 331 developed Parkinson’s disease during the follow-up period, with a median time to diagnosis of 4.9 years after the first recorded episode of anxiety.

The incidence of Parkinson’s disease was 1.2 per 1000 person-years (95% CI, 0.92-1.13) in those with anxiety versus 0.49 (95% CI, 0.47-0.52) in those without anxiety.

After adjustment for age, sex, social deprivation, lifestyle factors, severe mental illness, head trauma, and dementia, the risk for Parkinson’s disease was double in those with anxiety, compared with the non-anxiety group (hazard ratio, 2.1; 95% CI, 1.9-2.4).

Individuals without anxiety also developed Parkinson’s disease later than those with anxiety.

The researchers identified specific symptoms that were associated with later development of Parkinson’s disease in those with anxiety, including depression, sleep disturbance, fatigue, and cognitive impairment, among other symptoms.

“The results suggest that there is a strong association between anxiety and diagnosis of Parkinson’s disease in patients aged over 50 years who present with a new diagnosis of anxiety,” the authors wrote. “This provides evidence for anxiety as a prodromal presentation of Parkinson’s disease.”

Future research “should explore anxiety in relation to other prodromal symptoms and how this symptom complex is associated with the incidence of Parkinson’s disease,” the researchers wrote. Doing so “may lead to earlier diagnosis and better management of Parkinson’s disease.”

This study was funded by the European Union. Specific authors received funding from the National Institute for Health and Care Research and the Alzheimer’s Society Clinical Training Fellowship program. The authors declared no relevant financial relationships.

New research supports current guidelines cautioning against long-term use of benzodiazepines.

The study of more than 5000 older adults found that benzodiazepine use was associated with an accelerated reduction in the volume of the hippocampus and amygdala — brain regions involved in memory and mood regulation. However, benzodiazepine use overall was not associated with an increased risk for dementia.

The findings suggest that benzodiazepine use “may have subtle, long-term impact on brain health,” lead investigator Frank Wolters, MD, PhD, with Erasmus University Medical Center, Rotterdam, the Netherlands, and colleagues wrote.

The study was published online in BMC Medicine.
 

Conflicting Evidence 

Benzodiazepines are commonly prescribed in older adults for anxiety and sleep disorders. Though the short-term cognitive side effects are well documented, the long-term impact on neurodegeneration and dementia risk remains unclear. Some studies have linked benzodiazepine use to an increased risk for dementia, whereas others have not.

Dr. Wolters and colleagues assessed the effect of benzodiazepine use on long-term dementia risk and on imaging markers of neurodegeneration in 5443 cognitively healthy adults (mean age, 71 years; 57% women) from the population-based Rotterdam Study. 

Benzodiazepine use between 1991 and 2008 was determined using pharmacy dispensing records, and dementia incidence was determined from medical records. 

Half of the participants had used benzodiazepines at any time in the 15 years before baseline (2005-2008); 47% used anxiolytics, 20% used sedative-hypnotics, 34% used both, and 13% were still using the drugs at the baseline assessment. 

During an average follow-up of 11 years, 13% of participants developed dementia. 

Overall, use of benzodiazepines was not associated with dementia risk, compared with never-use (hazard ratio [HR], 1.06), irrespective of cumulative dose. 

The risk for dementia was somewhat higher with any use of anxiolytics than with sedative-hypnotics (HR, 1.17 vs HR, 0.92), although neither was statistically significant. The highest risk estimates were observed for high cumulative dose of anxiolytics (HR, 1.33). 

Sensitivity analyses of the two most commonly used anxiolytics found no differences in risk between use of short half-life oxazepam and long half-life diazepam (HR, 1.01 and HR, 1.06, respectively, for ever-use, compared with never-use for oxazepam and diazepam).
 

Brain Atrophy

The researchers investigated potential associations between benzodiazepine use and brain volumes using brain MRI imaging from 4836 participants.

They found that current use of a benzodiazepine at baseline was significantly associated with lower total brain volume — as well as lower hippocampus, amygdala, and thalamus volume cross-sectionally — and with accelerated volume loss of the hippocampus and, to a lesser extent, amygdala longitudinally. 

Imaging findings did not differ by type of benzodiazepine used or cumulative dose. 

“Given the availability of effective alternative pharmacological and nonpharmacological treatments for anxiety and sleep problems, it is important to carefully consider the necessity of prolonged benzodiazepine use in light of potential detrimental effects on brain health,” the authors wrote. 
 

Risks Go Beyond the Brain

Commenting on the study, Shaheen Lakhan, MD, PhD, a neurologist and researcher based in Miami, Florida, noted that “chronic benzodiazepine use may reduce neuroplasticity, potentially interfering with the brain’s ability to form new connections and adapt.

“Long-term use can lead to down-regulation of GABA receptors, altering the brain’s natural inhibitory mechanisms and potentially contributing to tolerance and withdrawal symptoms. Prolonged use can also disrupt the balance of various neurotransmitter systems beyond just GABA, potentially affecting mood, cognition, and overall brain function,” said Dr. Lakhan, who was not involved in the study. 

“While the literature is mixed on chronic benzodiazepine use and dementia risk, prolonged use has consistently been associated with accelerated volume loss in certain brain regions, particularly the hippocampus and amygdala,” which are responsible for memory, learning, and emotional regulation, he noted. 

“Beyond cognitive impairments and brain volume loss, chronic benzodiazepine use is associated with tolerance and dependence, potential for abuse, interactions with other drugs, and increased fall risk, especially in older adults,” Dr. Lakhan added.

Current guidelines discourage long-term use of benzodiazepines because of risk for psychological and physical dependence; falls; and cognitive impairment, especially in older adults. Nevertheless, research shows that 30%-40% of older benzodiazepine users stay on the medication beyond the recommended period of several weeks.

Donovan T. Maust, MD, Department of Psychiatry, University of Michigan Medical School, Ann Arbor, said in an interview these new findings are consistent with other recently published observational research that suggest benzodiazepine use is not linked to dementia risk. 

“I realize that such meta-analyses that find a positive relationship between benzodiazepines and dementia are out there, but they include older, less rigorous studies,” said Dr. Maust, who was not part of the new study. “In my opinion, the jury is not still out on this topic. However, there are plenty of other reasons to avoid them — and in particular, starting them — in older adults, most notably the increased risk of fall injury as well as increased overdose risk when taken along with opioids.”

In a shifting landscape in dementia risk factors, cardiovascular health is now taking precedence.

That’s according to researchers from University College London (UCL) in the United Kingdom who analyzed 27 papers about dementia that had data collected over more than 70 years. They calculated what share of dementia cases were due to different risk factors. Their findings were recently published in the Lancet Public Health.

Top risk factors for dementia over the years have been hypertension, obesity, diabetes, education, and smoking, according to a news release on the findings. But the prevalence of risk factors has changed over the decades.

Researchers said smoking and education have become less important risk factors because of “population-level interventions,” such as stop-smoking campaigns and compulsory public education. On the other hand, obesity and diabetes rates have increased and become bigger risk factors.

Hypertension remains the greatest risk factor, even though doctors and public health groups are putting more emphasis on managing the condition, the study said.

“Cardiovascular risk factors may have contributed more to dementia risk over time, so these deserve more targeted action for future dementia prevention efforts,” said Naaheed Mukadam, PhD, an associate professor at UCL and the lead author of the study.

Eliminating modifiable risk factors could theoretically prevent 40% of dementia cases, the release said. 

The CDC says that an estimated 5.8 million people in the United States have Alzheimer’s disease and related dementias, including 5.6 million people ages 65 and older and about 200,000 under age 65. The UCL release said an estimated 944,000 in the U.K. have dementia.

A work group convened by the Alzheimer’s Association has released revised biology-based criteria for the diagnosis and staging of Alzheimer’s disease, including a new biomarker classification system that incorporates fluid and imaging biomarkers as well as an updated disease staging system. 

“Plasma markers are here now, and it’s very important to incorporate them into the criteria for diagnosis,” said senior author Maria C. Carrillo, PhD, Alzheimer’s Association chief science officer and medical affairs lead. 

The revised criteria are the first updates since 2018.

“Defining diseases biologically, rather than based on syndromic presentation, has long been standard in many areas of medicine — including cancer, heart disease, and diabetes — and is becoming a unifying concept common to all neurodegenerative diseases,” lead author Clifford Jack Jr, MD, with Mayo Clinic, Rochester, Minnesota, said in a news release from the Alzheimer’s Association. 

“These updates to the diagnostic criteria are needed now because we know more about the underlying biology of Alzheimer’s and we are able to measure those changes,” Dr. Jack added. 

The 2024 revised criteria for diagnosis and staging of Alzheimer’s disease were published online in Alzheimer’s & Dementia. 
 

Core Biomarkers Defined

The revised criteria define Alzheimer’s disease as a biologic process that begins with the appearance of Alzheimer’s disease neuropathologic change (ADNPC) in the absence of symptoms. Progression of the neuropathologic burden leads to the later appearance and progression of clinical symptoms.

The work group organized Alzheimer’s disease biomarkers into three broad categories: (1) core biomarkers of ADNPC, (2) nonspecific biomarkers that are important in Alzheimer’s disease but are also involved in other brain diseases, and (3) biomarkers of diseases or conditions that commonly coexist with Alzheimer’s disease.

Core Alzheimer’s biomarkers are subdivided into Core 1 and Core 2. 

Core 1 biomarkers become abnormal early in the disease course and directly measure either amyloid plaques or phosphorylated tau (p-tau). They include amyloid PET; cerebrospinal fluid (CSF) amyloid beta 42/40 ratio, CSF p-tau181/amyloid beta 42 ratio, and CSF total (t)-tau/amyloid beta 42 ratio; and “accurate” plasma biomarkers, such as p-tau217. 

“An abnormal Core 1 biomarker result is sufficient to establish a diagnosis of Alzheimer’s disease and to inform clinical decision making [sic] throughout the disease continuum,” the work group wrote. 

Core 2 biomarkers become abnormal later in the disease process and are more closely linked with the onset of symptoms. Core 2 biomarkers include tau PET and certain soluble tau fragments associated with tau proteinopathy (eg, MTBR-tau243) but also pT205 and nonphosphorylated mid-region tau fragments. 

Core 2 biomarkers, when combined with Core 1, may be used to stage biologic disease severity; abnormal Core 2 biomarkers “increase confidence that Alzheimer’s disease is contributing to symptoms,” the work group noted. 

The revised criteria give clinicians “the flexibility to use plasma or PET scans or CSF,” Dr. Carrillo said. “They will have several tools that they can choose from and offer this variety of tools to their patients. We need different tools for different individuals. There will be differences in coverage and access to these diagnostics.” 

The revised criteria also include an integrated biologic and clinical staging scheme that acknowledges the fact that common co-pathologies, cognitive reserve, and resistance may modify relationships between clinical and biologic Alzheimer’s disease stages. 
 

Formal Guidelines to Come 

The work group noted that currently, the clinical use of Alzheimer’s disease biomarkers is intended for the evaluation of symptomatic patients, not cognitively unimpaired individuals.

Disease-targeted therapies have not yet been approved for cognitively unimpaired individuals. For this reason, the work group currently recommends against diagnostic testing in cognitively unimpaired individuals outside the context of observational or therapeutic research studies. 

This recommendation would change in the future if disease-targeted therapies that are currently being evaluated in trials demonstrate a benefit in preventing cognitive decline and are approved for use in preclinical Alzheimer’s disease, they wrote. 

They emphasize that the revised criteria are not intended to provide step-by-step clinical practice guidelines for clinicians. Rather, they provide general principles to inform diagnosis and staging of Alzheimer’s disease that reflect current science.

“This is just the beginning,” said Dr. Carrillo. “This is a gathering of the evidence to date and putting it in one place so we can have a consensus and actually a way to test it and make it better as we add new science.”

This also serves as a “springboard” for the Alzheimer’s Association to create formal clinical guidelines. “That will come, hopefully, over the next 12 months. We’ll be working on it, and we hope to have that in 2025,” Dr. Carrillo said. 

The revised criteria also emphasize the role of the clinician. 

“The biologically based diagnosis of Alzheimer’s disease is meant to assist, rather than supplant, the clinical evaluation of individuals with cognitive impairment,” the work group wrote in a related commentary published online in Nature Medicine. 

Recent diagnostics and therapeutic developments “herald a virtuous cycle in which improvements in diagnostic methods enable more sophisticated treatment approaches, which in turn steer advances in diagnostic methods,” they continued. “An unchanging principle, however, is that effective treatment will always rely on the ability to diagnose and stage the biology driving the disease process.”
