A novel approach aimed at enhancing everyday memory may lead older adults to feel more confident that they can accurately recollect phone numbers, names, and other information, according to findings from a small randomized controlled trial that were presented at the annual meeting of the Gerontological Society of America.

The tool, called Everyday Memory and Metacognitive Intervention (EMMI), trains people to be more mindful of memories, like where they parked their car, by repeating information at increasing intervals and self-testing.

EMMI “is a very important approach, focused on everyday memory,” said George W. Rebok, PhD, professor emeritus in the department of mental health at Johns Hopkins University, Baltimore, who was not involved with the study. “Many times, when we do memory interventions, we only focus on improving objective memories,” such as recalling major life events or one-time occurrences.

Everyday memory was defined as recalling basic facts including names, phone numbers, and daily appointments. The research, led by Ann Pearman, MD, associate director of adult psychology at Case Western Reserve University School of Medicine at MetroHealth Medical Center, Cleveland, Ohio, expanded on previous work she conducted with colleagues. That study found that EMMI may help improve confidence in the ability to recollect information and functional independence among older adults.

The current study was of 62 of the same participants in the earlier research, with one group that received EMMI (n = 30) and another that underwent traditional memory strategy training ([MSC]; n = 32). Both groups underwent four 3-hour virtual training sessions in their designated intervention over 2 weeks.

“One of the most important parts of the study is the [training] period,” when participants build new habits to help recall their everyday memories, Dr. Pearman said.

For 7 weeks, participants reported errors in everyday memories on a smartphone and submitted diary entries for each. Dr. Rebok that said tracking can help identify patterns or circumstances under which a person is likely to experience a memory lapse.

The study found mixed results when comparing EMMI with MSC, with the latter group demonstrating greater improvements in associative memory, such as pairing of a name to a face, highlighting the effectiveness of traditional MCS.

However, participants who underwent EMMI reported an increase in self-confidence that they were able to remember things, compared with those in the MSC group (4.92, confidence interval 95%, P = .30).

The EMMI intervention also was not uniformly effective in reducing memory errors across all participants in the group, which is to be expected, experts note. “In memory training, as with any kind of cognitive training, one size doesn’t fit all,” Dr. Rebok said.

“The mixed findings may highlight the need for a holistic approach to memory improvement and brain health, especially in older adults,” said Krystal L. Culler, DBH, founder of the Virtual Brain Health Center in Cleveland, who was not involved with the study.

EMMI could potentially be part of a broader strategy that includes lifestyle factors like sleep hygiene, physical exercise, diet, and social engagement to support optimal memory care, Dr. Culler said.

Patients who noticed some change in their memory and who are interested in making some positive changes in their daily cognitive functioning may benefit most from EMMI, according to Dr. Pearman.

“Making proactive decisions about memory challenges [patients] in their thinking and doing in everyday life,” she said.

Dr. Pearman shared that she and her colleagues are now looking into a combined EMMI and traditional memory strategy training to maximize the benefits of both interventions.

The study was supported by the Retirement Research Foundation (2018-2019); and the National Institute of Diabetes and Digestive and Kidney Diseases (P30DK111024) from the Georgia Center for Diabetes Translation Research. The study authors report no relevant conflicts. Dr. Culler and Dr. Rebok report no relevant financial relationships.

I was running my 25th New York City Marathon. It was 2018, and I almost pulled out of running that year. I wasn’t myself, and maybe that’s an understatement.

A month earlier, I had been involved in a malpractice case. I was found liable for $10 million. My colleagues didn’t think I had done anything wrong, but the jury did. And the local newspapers made me look like a villain.

I was devastated. But my priest, my friends, and my family all told me, “You can’t quit.” So, I decided to run for them.

I started on the Verrazzano-Narrows Bridge that morning with some friends from work. I usually listen to music as I’m running, but I didn’t that year. I was just in my zone, enjoying the crowds. They’re huge. Millions of people on the streets.

I was running well. I did half the race in an hour and 57 minutes. My family always meets me at mile 17, and I was almost there. I had reached 59th Street and was about to make the turn onto First Avenue.

That’s one of the noisiest places in the marathon. There’s a kind of tunnel, and with the crowd and the throng of runners, it’s incredibly loud. But somehow, I heard somebody yell, “Help!”

Now, how I heard that, I don’t know. And if I’d been listening to music like I always do, no way I would’ve heard it. I could swear it was an angel on my shoulder that said, “Turn around, dummy. You’ve got a person that needs your help to your left.”

I turned around and about 30 feet behind me, I saw a woman waving her hands and a runner on the ground. I thought, Somebody fainted. I pushed through the crowd to get to them. The woman was crying, saying, “My friend went down to tie her shoe and she fell back. I think she’s seizing or something.”

I got down and tried to wake the other woman up. I lifted her legs up. But I quickly realized there was more to the story. I felt for pulses and couldn’t feel them. I screamed for a defibrillator and started to do CPR.

Some volunteers and police started coming toward us. The police officers looked at me like, What’s this guy doing? I explained that I was a physician, and one of them began helping me with the CPR. As we did that, someone brought a defibrillator.

Meanwhile, runners were going past, almost over us. The police officers were trying to create a barrier.

The machine gave the woman a shock, but we didn’t get a response, so we resumed CPR. At that point, my legs began to cramp so badly I couldn’t go on. So the police officer took over, and I yelled, “I need an ambu bag!” Somebody brought one, and I started giving her oxygen.

At that point, a paramedic team arrived with a bigger defibrillator. We shocked her again. And again. That time we got results, but she quickly went out again. The fourth time, we got her heart back and she started breathing on her own.

We finally got her into an ambulance. I wanted to go with them, but the woman’s friend needed to get in, so there wasn’t enough room.

And then they were gone, and I was just standing there.

A police officer put his arm around me. He said, “Doc, you’re amazing. What do you need? Where can I take you?”

I said, “Take me? My wife is waiting for me at mile 17.”

I took off and ran. When I got to my wife and kids, they were so worried. We all wear tracking devices, and they could see that I had stopped for more than 20 minutes.

I fell into my wife’s arms and told her what had happened. I was crying. “I don’t know what to do. I need to get to the hospital.”

And she said, “No, you need to go finish the race.”

So, I did. It was painful because of the cramps, but I was numb at that point. I was thinking about the woman the whole way. My time was 5 hours and 20 minutes.

As soon as I finished, I went to every police officer I could find, but nobody knew anything. Suddenly, I remembered my cousin. He had previously been the head of EMS for New York City. I called him. “Abdo, it’s Ted, you’ve got to do me a favor.”

“What?” he said. “Are you delirious from running the marathon?”

I told him what I needed. He called me back 5 minutes later and said, “Ted, what’d you do? Everybody wants to know who you are and where you are! The woman just went out again at New York Cornell. But they got her back, and they’re bringing her up to the cath lab.”

After every marathon that I run, we host a big party at our house. My family and friends and neighbors all celebrate while I’m dying on the couch. That night, my daughter told everyone the story of what happened.

But I was still not right. Still thinking about the malpractice suit.

Yes, I just did something great. But I’d recently been called the worst physician in the world. The distraction of the marathon was gone, and I was back to thinking, What am I going to do with my life? Who’s ever going to want to see me again? I’m a pariah.

Everybody said, “Ted, what happened a month ago isn’t you. What happened today was you.”

I told them to leave it alone, but my daughter and my neighbor started calling people anyway. The next day I got a call from the local newspaper. It was the same journalist who had written about me from the trial. I told him I didn’t want to talk. I was actually pretty nasty.

But my wife said, “Ted, what are you doing? That guy was trying to help you.” So, I called back and apologized.

“Dr. Strange, we knew that story wasn’t right,” he said. “We have to write this story.”

After the article came out, I started getting more calls from the media. Channel 7 News and CBS News did segments. The New York Knicks invited us to a game and presented me with a watch. It was incredible. But I was also really embarrassed by it.

People started calling me a hero. I’m not a hero. I just did what I’m supposed to do, what I’m trained to do. Shame on me if I don’t do that. Good guy and hopefully good physician, sure, but not a hero.

I also give credit to the City of New York Police Department, the FDNY, and the volunteers. Without them, I couldn’t have done what I did. It was a true team effort.

A few weeks later, the woman went home to Minnesota. She’ll never run a marathon again, but she’s still alive to this day. It turned out she had a single lesion called the “widow-maker” lesion. She was in perfect health and had just completed an ultramarathon a few months before; but she had a genetic predisposition. She still calls me every December to thank me for another Christmas.

There’s more.

One year after this whole thing, almost to the date, I got a call from my attorney. “The court just threw out the malpractice verdict,” he said. “You didn’t do anything wrong.”

I’m a man of faith. And I believe all this happened for a reason. Maybe God was sending me a message, and that’s why I heard a call for help on 59th Street in my 25th marathon among millions of people in a crowd.

I ran the marathon the next year. And when I got to that spot, I stopped and reflected. Nobody knew why I was standing there, but I knew. To this day, I could take you to that spot.

I turn 65 next July, and I plan to keep on running the race.

I turn 65 next July, and I plan to keep on running the race.

Headache and headache associated with mood disorders are common among individuals from the LGBTQIA+ community, but preconceptions should be abandoned in a diverse population fearful that their gender identity or sexual orientation will lead to mistreatment.

It is “important not to assume that just because someone is a member of the LGBTQ+ community they will need psychiatric or behavioral health support,” said Maya A. Marzouk, PhD, division of behavioral medicine and clinical psychology, Cincinnati Children’s Hospital Medical Center.

Instead, it is useful not to make any assumptions. There is a potential association between minority status and headache susceptibility, but it is more reasonable initially to address the diagnosis and treatment of headache in LGBTQIA+ patients the same way it is addressed in any other patient, Dr. Marzouk said at the 2023 Scottsdale Headache Symposium.

The acronym to describe individuals with gender identities different from male and female and sexual orientations not limited to heterosexuality has been in almost constant evolution over several decades. An addition sign that accompanies LGBTQIA refers to those who do not identify with any letters in the acronym (lesbian, gay, bisexual, transsexual, queer/questioning, intersex, and asexual).
 

Take steps to normalize the interaction

Although many clinicians have been acclimated to these diverse identifies, not all have risen above preconceptions that become obstacles to effective care, according to Dr. Marzouk. In the context of headache management, Dr. Marzouk emphasized the need to be respectful of the range of gender identities and sexual orientations and to take steps to normalize the interaction.

For example, Dr. Marzouk advised using gender-neutral language at the start of each patient encounter and ask open-ended questions about gender, sexual identify, and pronouns to avoid patient discomfort from misidentification. In turn, the clinicians can establish their own gender identification and preferred pronouns to reinforce the idea that doing so is normal behavior.

This change in approach should be made “for all patients. Do not try to guess who needs them,” she said.

Intake forms and office atmosphere, such as signs and images, should also be welcoming to all patients, she added. Rather than trying to make adjustments for a LGBTQIA+ visit, Dr. Marzouk said a uniform approach helps normalize the experience of LGBTQIA+ patients without singling them out.

Despite the effort to provide an open and welcoming environment, Dr. Marzouk acknowledged that mistakes are difficult to avoid for those with limited experience serving the LGBTQIA+ community. When mistakes are made, she advised clinicians to immediately acknowledge the mistake and ask for guidance from the patient.

The potential offense is making the patient feel “other” or abnormal.
 

A higher rate of migraine

The interactions that LBGTQIA+ patients have with others outside their community is a possible explanation for the substantial rate of headache as well as headache with comorbid psychiatric disorders in this population.

In a survey published in 2020, the rate of migraine was 19.7% in heterosexual women, 26.7% in lesbians, and 36.8% in bisexual women. Among men, it rose from 9.8% in heterosexuals to 14.8% in gays and then to 22.8% in bisexuals.

Migraine relative to headache is also associated with more mood disorders among LGBTQIA+ individuals. In a study published in 2022, LGBTQIA+ patients with migraine relative to those with headache were more likely to have depression (46.4% vs. 22.3%; P < .001), anxiety (72.1% vs. 51.6%; P < .001), and posttraumatic stress disorder (37.5% vs. 21.4%; P < .001).
 

A vicious cycle of underdiagnosis and undertreatment

These associations are consistent with minority stress theory, according to Dr. Marzouk. This theory postulates that the associated stress of discrimination, rejection, and microaggressions, such as explicit efforts to make LGBTQIA+ individuals to feel “other,” produces epigenetic changes and dysregulation of the hypothalamic-pituitary-adrenal axis. In turn, this plays a role in the pathogenesis of migraine.

The inconsistency with which minority stress affects LGBTQIA+ patients might be due to relative differences in social support, coping skills, an innate resilience to these effects, Dr. Marzouk explained.

Dr. Marzouk characterized the LGBTQIA+ community as “underserved” for treatment of headache. She suggested that medical mistrust and self-blame among LGBTQIA+ individuals might be factors contributing to a vicious cycle of underdiagnosis and undertreatment. Efforts by the medical community to reach out to the LGBTQIA+ community are appropriate to address an unmet need.

“Individuals with psychiatric comorbidities may experience even more benefit from migraine care,” she said.
 

Clinical studies should be more inclusive

While agreeing in principle with these remarks, Eric A. Kaiser, MD, PhD, department of neurology, University of Pennsylvania, Philadelphia, said that this area would be better advanced if studies routinely included patients with diverse-gender identities and sexual orientations. Speaking about how to organize these studies, Dr. Kaiser suggested that enrollment criteria should explicitly seek these individuals and that these differences should be captured in the baseline characteristics.

“For example, gender options could include man, woman, non-binary, gender diverse, gender nonconforming, or gender nonspecified,” he said.

To close “the significant knowledge gap that exists in managing headache disorders in sexually- and gender- diverse people,” Dr. Kaiser said that clinical research studies, like patient treatment of diverse populations, “should be conducted with welcoming and affirming practices.”

Dr. Marzouk reported no potential conflicts of interest. Dr. Kaiser reported financial relationships with Amgen and Lundbeck.

TOPLINE:

Exposure to air pollutants is linked to emergency hospital admissions for stroke shortly after the exposure, with the risk being pronounced in men and individuals aged less than 65 years.

METHODOLOGY:

• Limited studies have investigated the association between hourly exposure to air pollutants and specific stroke subtypes, especially in regions with moderate to high levels of air pollution.
• The multicenter case-crossover study evaluated the association between hourly exposure to air pollution and stroke among 86,635 emergency admissions for stroke across 10 hospitals in 3 cities.
• Of 86,635 admissions, 79,478 were admitted for ischemic stroke, 3,122 for hemorrhagic stroke, and 4,035 for undetermined type of stroke.
• Hourly levels of fine particulate matter (PM2.5), respirable PM (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were collected from the China National Environmental Monitoring Center.

TAKEAWAY:

• Exposure to NO2 and SO2 increased the risk for emergency admission for stroke shortly after exposure by 3.34% (95% confidence interval, 1.41%-5.31%) and 2.81% (95% CI, 1.15%-4.51%), respectively.
• Among men, exposure to PM2.5 and PM10 increased the risk for emergency admission for stroke by 3.40% (95% CI, 1.21%-5.64%) and 4.33% (95% CI, 2.18%-6.53%), respectively.
• Among patients aged less than 65 years, exposure to PM10 and NO2 increased the risk for emergency admissions for stroke shortly after exposure by 4.88% (95% CI, 2.29%-7.54%) and 5.59% (95% CI, 2.34%-8.93%), respectively.

IN PRACTICE:

“These variations in susceptibility highlight the importance of implementing effective health protection measures to reduce exposure to air pollution and mitigate the risk of stroke in younger and male populations,” wrote the authors.

SOURCE:

The study was led by Xin Lv, MD, department of epidemiology and biostatistics, School of Public Health, Capital Medical University, Beijing. It was published online in the journal Stroke.

LIMITATIONS:

• Using data from the nearest monitoring site to the hospital address may lead to localized variations in pollution concentrations when assessing exposure.
• There may be a possibility of residual confounding resulting from time-varying lifestyle-related factors.

DISCLOSURES:

This study was supported by the Zhejiang Provincial Project for Medical Research and Health Sciences. No disclosures were reported.

A patient with Parkinson’s disease (PD) can now walk with a normal gait without balance problems or fear of falling after implantation of a neuroprosthetic device.

The neuroprosthesis involves targeted epidural electrical stimulation of areas of the lumbosacral spinal cord that produce walking.

This new therapeutic tool offers hope to patients with PD and, combined with existing approaches, may alleviate a motor sign in PD for which there is currently “no real solution,” study investigator Eduardo Martin Moraud, PhD, who leads PD research at the Defitech Center for Interventional Neurotherapies (NeuroRestore), Lausanne, Switzerland, said in an interview.

“This is exciting for the many patients that develop gait deficits and experience frequent falls, who can only rely on physical therapy to try and minimize the consequences,” he added.

The findings were published online in Nature Medicine.
 

Personalized stimulation

About 90% of people with advanced PD experience gait and balance problems or freezing-of-gait episodes. These locomotor deficits typically don’t respond well to dopamine replacement therapy or deep brain stimulation (DBS) of the subthalamic nucleus, possibly because the neural origins of these motor problems involve brain circuits not related to dopamine, said Dr. Moraud.

Continuous electrical stimulation over the cervical or thoracic segments of the spinal cord reduces locomotor deficits in some people with PD, but the broader application of this strategy has led to variable and unsatisfying outcomes.

The new approach focuses on correcting abnormal activation of circuits in the lumbar spinal cord, a region that hosts all the neurons that control activation of the leg muscles used for walking.

The stimulating device is placed on the lumbar region of the spinal cord, which sends messages to leg muscles. It is wired to a small impulse generator implanted under the skin of the abdomen. Sensors placed in shoes align the stimulation to the patient’s movement.

The system can detect the beginning of a movement, immediately activate the appropriate electrode, and so facilitate the necessary movement, be that leg flexion, extension, or propulsion, said Dr. Moraud. “This allows for increased walking symmetry, reinforced balance, and increased length of steps.”

The concept of this neuroprosthesis is similar to that used to allow patients with a spinal cord injury (SCI) to walk. But unlike patients with SCI, those with PD can move their legs, indicating that there is a descending command from the brain that needs to interact with the stimulation of the spinal cord, and patients with PD can feel the stimulation.

“Both these elements imply that amplitudes of stimulation need to be much lower in PD than SCI, and that stimulation needs to be fully personalized in PD to synergistically interact with the descending commands from the brain.”

After fine-tuning this new neuroprosthesis in animal models, researchers implanted the device in a 62-year-old man with a 30-year history of PD who presented with severe gait impairments, including marked gait asymmetry, reduced stride length, and balance problems.
 

Gait restored to near normal

The patient had frequent freezing-of-gait episodes when turning and passing through narrow paths, which led to multiple falls a day. This was despite being treated with DBS and dopaminergic replacement therapies.

But after getting used to the neuroprosthesis, the patient now walks with a gait akin to that of people without PD.

“Our experience in the preclinical animal models and this first patient is that gait can be restored to an almost healthy level, but this, of course, may vary across patients, depending on the severity of their disease progression, and their other motor deficits,” said Dr. Moraud.

When the neuroprosthesis is turned on, freezing of gait nearly vanishes, both with and without DBS.

In addition, the neuroprosthesis augmented the impact of the patient’s rehabilitation program, which involved a variety of regular exercises, including walking on basic and complex terrains, navigating outdoors in community settings, balance training, and basic physical therapy.

Frequent use of the neuroprosthesis during gait rehabilitation also translated into “highly improved” quality of life as reported by the patient (and his wife), said Dr. Moraud.

The patient has now been using the neuroprosthesis about 8 hours a day for nearly 2 years, only switching it off when sitting for long periods of time or while sleeping.

“He regained the capacity to walk in complex or crowded environments such as shops, airports, or his own home, without falling,” said Dr. Moraud. “He went from falling five to six times per day to one or two [falls] every couple of weeks. He’s also much more confident. He can walk for many miles, run, and go on holidays, without the constant fear of falling and having related injuries.”

Dr. Moraud stressed that the device does not replace DBS, which is a “key therapy” that addresses other deficits in PD, such as rigidity or slowness of movement. “What we propose here is a fully complementary approach for the gait problems that are not well addressed by DBS.”

One of the next steps will be to evaluate the efficacy of this approach across a wider spectrum of patient profiles to fully define the best responders, said Dr. Moraud.
 

A ‘tour de force’

In a comment, Michael S. Okun, MD, director of the Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, and medical director of the Parkinson’s Foundation, noted that the researchers used “a smarter device” than past approaches that failed to adequately address progressive walking challenges of patients with PD.

Although it’s “tempting to get excited” about the findings, it’s important to consider that the study included only one human subject and did not target circuits for both walking and balance, said Dr. Okun. “It’s possible that even if future studies revealed a benefit for walking, the device may or may not address falling.”

In an accompanying editorial, Aviv Mizrahi-Kliger, MD, PhD, department of neurology, University of California, San Francisco, and Karunesh Ganguly, MD, PhD, Neurology and Rehabilitation Service, San Francisco Veterans Affairs Health Care System, called the study an “impressive tour de force,” with data from the nonhuman primate model and the individual with PD “jointly” indicating that epidural electrical stimulation (EES) “is a very promising treatment for several aspects of gait, posture and balance impairments in PD.”

But although the effect in the single patient “is quite impressive,” the “next crucial step” is to test this approach in a larger cohort of patients, they said.

They noted the nonhuman model does not exhibit freezing of gait, “which precluded the ability to corroborate or further study the role of EES in alleviating this symptom of PD in an animal model.”

In addition, stimulation parameters in the patient with PD “had to rely on estimated normal activity patterns, owing to the inability to measure pre-disease patterns at the individual level,” they wrote.

The study received funding from the Defitech Foundation, ONWARD Medical, CAMS Innovation Fund for Medical Sciences, National Natural Science Foundation of China, Parkinson Schweiz Foundation, European Community’s Seventh Framework Program (NeuWalk), European Research Council, Wyss Center for Bio and Neuroengineering, Bertarelli Foundation, and Swiss National Science Foundation. Dr. Moraud and other study authors hold various patents or applications in relation to the present work. Dr. Mizrahi-Kliger has no relevant conflicts of interest; Dr. Ganguly has a patent for modulation of sensory inputs to improve motor recovery from stroke and has been a consultant to Cala Health.

The patient had frequent freezing-of-gait episodes when turning and passing through narrow paths, which led to multiple falls a day. This was despite being treated with DBS and dopaminergic replacement therapies.

But after getting used to the neuroprosthesis, the patient now walks with a gait akin to that of people without PD.

“Our experience in the preclinical animal models and this first patient is that gait can be restored to an almost healthy level, but this, of course, may vary across patients, depending on the severity of their disease progression, and their other motor deficits,” said Dr. Moraud.

When the neuroprosthesis is turned on, freezing of gait nearly vanishes, both with and without DBS.

In addition, the neuroprosthesis augmented the impact of the patient’s rehabilitation program, which involved a variety of regular exercises, including walking on basic and complex terrains, navigating outdoors in community settings, balance training, and basic physical therapy.

Frequent use of the neuroprosthesis during gait rehabilitation also translated into “highly improved” quality of life as reported by the patient (and his wife), said Dr. Moraud.

The patient has now been using the neuroprosthesis about 8 hours a day for nearly 2 years, only switching it off when sitting for long periods of time or while sleeping.

“He regained the capacity to walk in complex or crowded environments such as shops, airports, or his own home, without falling,” said Dr. Moraud. “He went from falling five to six times per day to one or two [falls] every couple of weeks. He’s also much more confident. He can walk for many miles, run, and go on holidays, without the constant fear of falling and having related injuries.”

Dr. Moraud stressed that the device does not replace DBS, which is a “key therapy” that addresses other deficits in PD, such as rigidity or slowness of movement. “What we propose here is a fully complementary approach for the gait problems that are not well addressed by DBS.”

One of the next steps will be to evaluate the efficacy of this approach across a wider spectrum of patient profiles to fully define the best responders, said Dr. Moraud.
 

A ‘tour de force’

In a comment, Michael S. Okun, MD, director of the Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, and medical director of the Parkinson’s Foundation, noted that the researchers used “a smarter device” than past approaches that failed to adequately address progressive walking challenges of patients with PD.

Although it’s “tempting to get excited” about the findings, it’s important to consider that the study included only one human subject and did not target circuits for both walking and balance, said Dr. Okun. “It’s possible that even if future studies revealed a benefit for walking, the device may or may not address falling.”

In an accompanying editorial, Aviv Mizrahi-Kliger, MD, PhD, department of neurology, University of California, San Francisco, and Karunesh Ganguly, MD, PhD, Neurology and Rehabilitation Service, San Francisco Veterans Affairs Health Care System, called the study an “impressive tour de force,” with data from the nonhuman primate model and the individual with PD “jointly” indicating that epidural electrical stimulation (EES) “is a very promising treatment for several aspects of gait, posture and balance impairments in PD.”

But although the effect in the single patient “is quite impressive,” the “next crucial step” is to test this approach in a larger cohort of patients, they said.

They noted the nonhuman model does not exhibit freezing of gait, “which precluded the ability to corroborate or further study the role of EES in alleviating this symptom of PD in an animal model.”

In addition, stimulation parameters in the patient with PD “had to rely on estimated normal activity patterns, owing to the inability to measure pre-disease patterns at the individual level,” they wrote.

The study received funding from the Defitech Foundation, ONWARD Medical, CAMS Innovation Fund for Medical Sciences, National Natural Science Foundation of China, Parkinson Schweiz Foundation, European Community’s Seventh Framework Program (NeuWalk), European Research Council, Wyss Center for Bio and Neuroengineering, Bertarelli Foundation, and Swiss National Science Foundation. Dr. Moraud and other study authors hold various patents or applications in relation to the present work. Dr. Mizrahi-Kliger has no relevant conflicts of interest; Dr. Ganguly has a patent for modulation of sensory inputs to improve motor recovery from stroke and has been a consultant to Cala Health.

A patient with Parkinson’s disease (PD) can now walk with a normal gait without balance problems or fear of falling after implantation of a neuroprosthetic device.

The neuroprosthesis involves targeted epidural electrical stimulation of areas of the lumbosacral spinal cord that produce walking.

This new therapeutic tool offers hope to patients with PD and, combined with existing approaches, may alleviate a motor sign in PD for which there is currently “no real solution,” study investigator Eduardo Martin Moraud, PhD, who leads PD research at the Defitech Center for Interventional Neurotherapies (NeuroRestore), Lausanne, Switzerland, said in an interview.

“This is exciting for the many patients that develop gait deficits and experience frequent falls, who can only rely on physical therapy to try and minimize the consequences,” he added.

The findings were published online in Nature Medicine.
 

Personalized stimulation

About 90% of people with advanced PD experience gait and balance problems or freezing-of-gait episodes. These locomotor deficits typically don’t respond well to dopamine replacement therapy or deep brain stimulation (DBS) of the subthalamic nucleus, possibly because the neural origins of these motor problems involve brain circuits not related to dopamine, said Dr. Moraud.

Continuous electrical stimulation over the cervical or thoracic segments of the spinal cord reduces locomotor deficits in some people with PD, but the broader application of this strategy has led to variable and unsatisfying outcomes.

The new approach focuses on correcting abnormal activation of circuits in the lumbar spinal cord, a region that hosts all the neurons that control activation of the leg muscles used for walking.

The stimulating device is placed on the lumbar region of the spinal cord, which sends messages to leg muscles. It is wired to a small impulse generator implanted under the skin of the abdomen. Sensors placed in shoes align the stimulation to the patient’s movement.

The system can detect the beginning of a movement, immediately activate the appropriate electrode, and so facilitate the necessary movement, be that leg flexion, extension, or propulsion, said Dr. Moraud. “This allows for increased walking symmetry, reinforced balance, and increased length of steps.”

The concept of this neuroprosthesis is similar to that used to allow patients with a spinal cord injury (SCI) to walk. But unlike patients with SCI, those with PD can move their legs, indicating that there is a descending command from the brain that needs to interact with the stimulation of the spinal cord, and patients with PD can feel the stimulation.

“Both these elements imply that amplitudes of stimulation need to be much lower in PD than SCI, and that stimulation needs to be fully personalized in PD to synergistically interact with the descending commands from the brain.”

After fine-tuning this new neuroprosthesis in animal models, researchers implanted the device in a 62-year-old man with a 30-year history of PD who presented with severe gait impairments, including marked gait asymmetry, reduced stride length, and balance problems.

Changes may be in store for how physicians do business based on pending proposals from the Federal Trade Commission to ban noncompete clauses and monitor potential merger monopolies.

In January 2023, the FTC announced a rule that would ban noncompete clauses, stating that such clauses reduce workers’ wages and stifle new businesses. Simply put, the rule would ban employers from entering into noncompete clauses with workers, including independent contractors.

Aspects of the rule include whether it should pertain to franchisees, whether senior executives should be exempted, and whether low-wage and high-wage workers should be treated differently.

According to the FTC, banning noncompete clauses would increase workers’ earnings by approximately $300 billion per year, save consumers as much as $148 billion in health care costs, and double the number of companies founded by former workers in the same field.

In June 2023, the FTC and the Department of Justice proposed changes to rules governing mergers, including changes to prenotification forms that would promote more efficient screening of potential mergers. According to a press release from the FTC, the proposed changes include provision of details about investments or corporate relationships, product and services, projected revenue streams, and previous acquisitions.

The proposal also includes a waiting period during which agencies would assess the risk that a merger would lessen competition or tend to create a monopoly.
 

What the FTC proposals mean for physicians

FTC Chair Lina M. Khan addressed attendees at the American College of Physicians at their annual meeting in October.

In March 2023, ACEP wrote to Ms. Khan in support of the banning of noncompete clauses. The ACEP also stated that the FTC should monitor the effect of a ban on the ability to recruit and maintain a stable physician workforce in rural and underserved areas “and should examine the potential impacts should nonprofit health systems be exempt from a ban.”

However, the American Medical Group Association, a nonprofit trade organization that supports multispecialty medical groups, opposes the ban. In a press release issued in March 2023, AMGA noted that, “As employers, AMGA members rely in part on noncompete agreements to build strong, sustainable care teams that work together to coordinate care for their patients. These care teams emphasize the importance of the doctor-patient relationship, which reasonable noncompete agreements help support.”

The American Medical Association supports the ban on noncompete clauses, detailed in an official AMA policy statement as, “support[ing] policies, regulations, and legislation that prohibits covenants not-to-compete for all physicians in clinical practice who hold employment contracts with for-profit or nonprofit hospital, hospital system, or staffing company employers.”

In regard to the merger guidelines, ACEP wrote a separate letter to Ms. Khan identifying some of the unique aspects of emergency medicine practice. The ACEP stressed the need for caution as the consolidation of medical practices continues, many under the umbrella of private equity investment companies.

“Unchecked mergers that substantially lessen competition in the labor market for emergency physicians, in which the employer is the buyer and the physician is the seller, can impact physicians directly by lowering wages or slowing wage growth, worsening benefits or working conditions, or contributing to other degradations in workplace quality,” according to ACEP.

The AMA also supports the FTC’s draft merger guidelines as protective of physicians and their working environments.

In September 2023, the AMA sent a letter to the FTC commending the agency on the proposed guidelines: “It is our strong contention that the agencies must have merger guidelines that protect physicians against health insurer mergers that may substantially lessen competition for the purchase of physician services and that degrade physician working conditions,” according to the AMA letter.

According the FTC, the proposed changes represent an expansion and reorganization of information along with the addition of new document requirements and represents the first comprehensive review of the Hart-Scott-Rodino Antitrust Improvements Act since 1978.

After soliciting public comments, the FTC is reviewing the proposals, and no specific date for a final vote has been announced.

More specifics on the potential changes to premerger notification, reporting, and waiting period requirements are available on the FTC website.

PHOENIX – Early responders to zilucoplan, the newly approved medication for myasthenia gravis, have sustained benefit for up to 60 weeks, a new analyses show.

“The information [in the studies] is valuable in making clinical decisions in managing myasthenia gravis, which is a chronic autoimmune condition that requires long-term use of immunosuppressives,” said Xinli Du, MD, PhD, an assistant professor in the department of neurology at Virginia Commonwealth University in Richmond, who was not involved in the research.

“Compared with conventional immunosuppressants, which take 3-9 months to know if the patient will respond, this is definitely a game-changer,” she said.

The research was presented at the 2023 annual meeting of the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM).
 

FDA approval

Approved by the U.S. Food and Drug Administration in October, the targeted peptide inhibitor of complement component 5 represents the only once-daily self-administered subcutaneous injection for adult patients with acetylcholine receptor autoantibody–positive (AChR+) generalized myasthenia gravis.

The multicenter, phase 3, placebo-controlled RAISE trial demonstrated that zilucoplan was associated with significant improvement in myasthenia gravis–specific outcomes in adult patients with mild to severe AChR+ generalized myasthenia gravis.

Of note, approximately 40% of patients in the zilucoplan phase 2 and 3 clinical trials have a significant response as early as the first week of treatment. For the current post hoc analysis, first author Miriam Freimer, MD, and colleagues took a closer look at the longer-term outcomes in these patients in the ongoing RAISE-XT open-label extension study.

In these two double-blind studies, patients were randomly assigned to receive either daily subcutaneous injections of 0.3 mg/kg zilucoplan or placebo.

Among 93 patients receiving zilucoplan in the two studies, 40 (43%) were identified as early responders based on having at least a 3-point reduction from baseline on the Myasthenia Gravis Activities of Daily Living scale (MG-ADL) within 1 week of treatment, and 31 (33%) qualified based on having at least 5-point reductions in Quantitative Myasthenia Gravis (QMG), at week 1.

Of these early responders, more than 80% meeting the MG-ADL and 85% meeting QMG criteria continued to show a treatment response at each assessment through week 60 in the open-label RAISE-XT trial.

Furthermore, week 1 responders maintained their response for 88.1% of their total treatment time in the MG-ADL group and 88.8% of their total treatment time on treatment in the QMG group, representing a median zilucoplan treatment duration of 450 days.

Of note, the week 1 early responders had no significant differences, compared with the study’s overall population. Participants had a mean age of 49.6 years versus 52.9 years in the overall population. Approximately 40% of patients in both studies were men, and 60%-64% were disease class III as assessed by the Myasthenia Gravis Foundation of America criteria.

“It is very exciting to see such a high response of rapid responders. This means that some patients may be able to avoid steroids or be able to taper them faster than with other accepted treatments for myasthenia gravis,” said Dr. Freimer, director of the division of neuromuscular disorders and the codirector of the Myasthenia Gravis Clinic at the Ohio State University in Columbus.
 

Impact on fatigue

In a separate post hoc analysis of patients who entered RAISE-XT, the researchers evaluated long-term effects of zilucoplan on fatigue.

Improvements in fatigue were already apparent at the end of the RAISE trial, with the least squares mean (LSM) change from baseline in fatigue assessed after 12 weeks with the Neuro-QOL T-score being –6.26 for zilucoplan (n = 86) compared with an increase of 2.65 for placebo (n = 88; LSM difference, –3.61; nominal P = .0060).

Patients who received placebo in the RAISE trial were able to switch to zilucoplan in the RAISE-XT open-label trail, and among those who did, fatigue, as measured in the T-scores, improved significantly within 1 week of switching.

Fatigue further improved out to week 16 in terms of T-scores for the placebo-switch as well as zilucoplan groups, and the improvements in the scores were sustained through week 60 (mean change from RAISE baseline, –10.71 [n = 42] and –9.15 [n = 42], respectively).

“Fatigue is a challenge for patients with [generalized myasthenia gravis]. Zilucoplan significantly and clinically meaningfully improved myasthenic fatigue versus placebo during RAISE,” the investigators report.

“Further improvements were observed during RAISE-XT and were sustained up to 60 weeks of treatment,” they added.
 

Favorable safety profile

Zilucoplan continued to show a favorable safety profile in the RAISE-XT trial and was well tolerated in the long term.

The most common adverse reactions (10% or more) in patients with generalized myasthenia gravis were injection-site reactions, upper respiratory tract infection, and diarrhea.

Though additional therapies have also recently entered the market for generalized myasthenia gravis, they are either intravenous or subcutaneous infusions requiring a health care professional to administer them.

“This self-administered medication allows patients to be more independent and can even travel since it is not dependent on an infusion center,” Dr. Freimer noted.

However, similar to the other complement inhibitors, zilucoplan carries a risk for infection, particularly meningitis, Dr. Du noted. “Complement meningitis vaccination protocol and close monitoring for signs of infection are required,” she said.

However, she added, “the rapid action benefits shown as early as week 1 are impressive, and potentially open the door to use as adjunctive therapy in myasthenia gravis crisis.”

“I think zilucoplan definitely adds more excitement to the already active field of myasthenia gravis management,” she said.

The study was funded by UCB Pharma. Dr. Freimer has reports she has served as a paid consultant for argenx, UCB Pharma, and Alexion Pharmaceuticals and reports research support from the National Institutes of Health, UCB Pharma, Jansen Pharmaceuticals, Alnylam, Avidity, and Fulcrum. Dr. Du reports no disclosures.

The most common adverse reactions (10% or more) in patients with generalized myasthenia gravis were injection-site reactions, upper respiratory tract infection, and diarrhea.

Though additional therapies have also recently entered the market for generalized myasthenia gravis, they are either intravenous or subcutaneous infusions requiring a health care professional to administer them.

“This self-administered medication allows patients to be more independent and can even travel since it is not dependent on an infusion center,” Dr. Freimer noted.

However, similar to the other complement inhibitors, zilucoplan carries a risk for infection, particularly meningitis, Dr. Du noted. “Complement meningitis vaccination protocol and close monitoring for signs of infection are required,” she said.

However, she added, “the rapid action benefits shown as early as week 1 are impressive, and potentially open the door to use as adjunctive therapy in myasthenia gravis crisis.”

“I think zilucoplan definitely adds more excitement to the already active field of myasthenia gravis management,” she said.

The study was funded by UCB Pharma. Dr. Freimer has reports she has served as a paid consultant for argenx, UCB Pharma, and Alexion Pharmaceuticals and reports research support from the National Institutes of Health, UCB Pharma, Jansen Pharmaceuticals, Alnylam, Avidity, and Fulcrum.

PHOENIX – Early responders to zilucoplan, the newly approved medication for myasthenia gravis, have sustained benefit for up to 60 weeks, a new analyses show.

“The information [in the studies] is valuable in making clinical decisions in managing myasthenia gravis, which is a chronic autoimmune condition that requires long-term use of immunosuppressives,” said Xinli Du, MD, PhD, an assistant professor in the department of neurology at Virginia Commonwealth University in Richmond, who was not involved in the research.

“Compared with conventional immunosuppressants, which take 3-9 months to know if the patient will respond, this is definitely a game-changer,” she said.

The research was presented at the 2023 annual meeting of the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM).
 

FDA approval

Approved by the U.S. Food and Drug Administration in October, the targeted peptide inhibitor of complement component 5 represents the only once-daily self-administered subcutaneous injection for adult patients with acetylcholine receptor autoantibody–positive (AChR+) generalized myasthenia gravis.

The multicenter, phase 3, placebo-controlled RAISE trial demonstrated that zilucoplan was associated with significant improvement in myasthenia gravis–specific outcomes in adult patients with mild to severe AChR+ generalized myasthenia gravis.

Of note, approximately 40% of patients in the zilucoplan phase 2 and 3 clinical trials have a significant response as early as the first week of treatment. For the current post hoc analysis, first author Miriam Freimer, MD, and colleagues took a closer look at the longer-term outcomes in these patients in the ongoing RAISE-XT open-label extension study.

In these two double-blind studies, patients were randomly assigned to receive either daily subcutaneous injections of 0.3 mg/kg zilucoplan or placebo.

Among 93 patients receiving zilucoplan in the two studies, 40 (43%) were identified as early responders based on having at least a 3-point reduction from baseline on the Myasthenia Gravis Activities of Daily Living scale (MG-ADL) within 1 week of treatment, and 31 (33%) qualified based on having at least 5-point reductions in Quantitative Myasthenia Gravis (QMG), at week 1.

Of these early responders, more than 80% meeting the MG-ADL and 85% meeting QMG criteria continued to show a treatment response at each assessment through week 60 in the open-label RAISE-XT trial.

Furthermore, week 1 responders maintained their response for 88.1% of their total treatment time in the MG-ADL group and 88.8% of their total treatment time on treatment in the QMG group, representing a median zilucoplan treatment duration of 450 days.

Of note, the week 1 early responders had no significant differences, compared with the study’s overall population. Participants had a mean age of 49.6 years versus 52.9 years in the overall population. Approximately 40% of patients in both studies were men, and 60%-64% were disease class III as assessed by the Myasthenia Gravis Foundation of America criteria.

“It is very exciting to see such a high response of rapid responders. This means that some patients may be able to avoid steroids or be able to taper them faster than with other accepted treatments for myasthenia gravis,” said Dr. Freimer, director of the division of neuromuscular disorders and the codirector of the Myasthenia Gravis Clinic at the Ohio State University in Columbus.
 

Impact on fatigue

In a separate post hoc analysis of patients who entered RAISE-XT, the researchers evaluated long-term effects of zilucoplan on fatigue.

Improvements in fatigue were already apparent at the end of the RAISE trial, with the least squares mean (LSM) change from baseline in fatigue assessed after 12 weeks with the Neuro-QOL T-score being –6.26 for zilucoplan (n = 86) compared with an increase of 2.65 for placebo (n = 88; LSM difference, –3.61; nominal P = .0060).

Patients who received placebo in the RAISE trial were able to switch to zilucoplan in the RAISE-XT open-label trail, and among those who did, fatigue, as measured in the T-scores, improved significantly within 1 week of switching.

Fatigue further improved out to week 16 in terms of T-scores for the placebo-switch as well as zilucoplan groups, and the improvements in the scores were sustained through week 60 (mean change from RAISE baseline, –10.71 [n = 42] and –9.15 [n = 42], respectively).

“Fatigue is a challenge for patients with [generalized myasthenia gravis]. Zilucoplan significantly and clinically meaningfully improved myasthenic fatigue versus placebo during RAISE,” the investigators report.

“Further improvements were observed during RAISE-XT and were sustained up to 60 weeks of treatment,” they added.
 

Favorable safety profile

Zilucoplan continued to show a favorable safety profile in the RAISE-XT trial and was well tolerated in the long term.

The most common adverse reactions (10% or more) in patients with generalized myasthenia gravis were injection-site reactions, upper respiratory tract infection, and diarrhea.

PHOENIX – Chemotherapy-induced peripheral neuropathy (CIPN) is linked to a decline in executive and neuromuscular function, a new finding that may increase the risk for compromised mobility and fall risk.

“Among older cancer survivors treated with chemotherapy, the presence of CIPN was independently associated with reduced executive function,” said study investigator Brendan L. McNeish, MD, of the department of physical medicine and rehabilitation, University of Pittsburgh.

“Importantly, given the emerging relationship of executive function with mobility in this population, stakeholders and clinicians are called to acknowledge that chemotherapy-related mobility declines in CIPN survivors are likely due to both neuromuscular and executive dysfunction,” he said.

The findings were presented at the 2023 annual meeting of the American Association for Neuromuscular and Electrodiagnostic Medicine (AANEM).
 

Research gap

Characterized by numbness, tingling, pain, and motor impairment, CIPN affects up to 50% of all patients with cancer that is treated with taxane-, platinum-, or vinca alkaloid–based chemotherapy. The condition is among the leading dose-limiting toxicities, potentially increasing mortality risk.

Though the effects of chemotherapy on cognitive function are well-established, less is known about a potential relationship between this side effect and CIPN, Dr. McNeish said.

“Chemotherapy can be neurotoxic, but few studies have linked neurotoxicity to the central nervous system and peripheral nervous system,” Dr. McNeish said.

To compare cognitive outcomes in patients treated with chemotherapy who did and did not develop CIPN, the investigators conducted a cross-sectional study that included 50 chemotherapy-treated cancer survivors at a single time point post chemotherapy. The mean age of participants was 65.6 years, and 90% were women.

Twenty-two (44%) patients had CIPN on the basis of patient-reported distal paresthesias or numbness that started when chemotherapy was initiated and was present at the time of study enrollment.

Patients with CIPN had a greater decline in executive function, compared with those without the condition, as measured by the Trail Making Test Part B (TMT-B; CIPN-positive, 84.9 sec vs. 59.1 sec, respectively; P = .01) and the Stroop Color and Word Test (SCWT; CIPN-positive, 178.1 sec vs. CIPN-negative, 152.7 sec; P = .04), as well as lower rapid reaction accuracy (CIPN-positive, 60.3% vs. CIPN-negative, 70.6%; P = .01).

The association between CIPN and decreased executive function remained after multivariate adjusting for age, gender, depression, and benzodiazepine use for TMT-B (beta, 18.7; P = .046) and rapid reaction accuracy (beta, -.088; P = .018) but not SCWT (beta, 9.52; P = .233).
 

Clinical guidance

A recent study by the same investigators showed a link between executive function and balance in cancer survivors (mean age, 65.6 years; 88% women) treated with chemotherapy.

Another study of 116 patients treated with chemotherapy, including 32 who developed CIPN, showed that those with CIPN were nearly three times more likely to report a fall or near fall than were those without CIPN symptoms. In addition, those with CIPN symptoms were also more likely to have received medical care for falls.

Based on the current findings, the research suggests that “current clinical approaches to caring for this growing population [of cancer patients] should not assume that the well-known increased fall risk is solely related to CIPN.”

Dr. McNeish speculated that two potential hypotheses could explain the association between CIPN and reduced executive function in older cancer survivors.

“First, CIPN is associated with other conditions such as depression and anxiety, which are associated with reduced executive function,” he said.

“The second is that cancer-related cognitive dysfunction and CIPN share pathogenic mechanisms of neuronal injury, inflammation, and advanced aging, and thus some patients are vulnerable to both central (cancer-related cognitive function) and peripheral neurotoxicity.”

Either way, Dr. McNeish noted that “all interventions should measure both CIPN and executive function, as one could confound the other.”
 

Need for increased awareness

Commenting on the study, Ting Bao, MD, co-director of the Leonard P. Zakim Center for Integrative Therapies & Healthy Living at the Dana-Farber Cancer Institute, Boston, said that the findings underscore that “there is a need for increased awareness of the diverse manifestations of chemotherapy-induced neuropathy.”

These include the fact that “neurotoxic chemotherapy impacts both the peripheral and central nervous systems, affecting balance through distinct mechanisms.”

Although treatments routinely recommended for CIPN include duloxetine, tricyclic antidepressants, or gabapentin as well as topical agents such as lidocaine, evidence also shows benefits of nonpharmacologic approaches including exercise, acupuncture, and yoga. Dr. Bao’s own research has suggested that those benefits can extend improved balance and reduced fall risk.

Dr. Bao and colleagues recently conducted a randomized study that included 41 patients with CIPN to receive either yoga or usual care.

“The findings revealed that after eight biweekly sessions of yoga, there was a notable improvement in the far-reach test, which is a predictor of fall risk,” she said.

To validate these findings, the researchers are currently conducting a larger randomized controlled trial, she said.

In the meantime, “further research into the mechanisms and effective treatments for chemotherapy-induced neurotoxicity is essential,” added Dr. Bao.

TOPLINE:

Adults with atrial fibrillation (AFib) are at increased risk for dementia, especially when AFib occurs before age 65 years, new research shows. Investigators note the findings highlight the importance of monitoring cognitive function in adults with AF.

METHODOLOGY:

• This prospective, population-based cohort study leveraged data from 433,746 UK Biobank participants (55% women), including 30,601 with AFib, who were followed for a median of 12.6 years
• Incident cases of dementia were determined through linkage from multiple databases.
• Cox proportional hazards models and propensity score matching were used to estimate the association between age at onset of AFib and incident dementia.

TAKEAWAY:

• During follow-up, new-onset dementia occurred in 5,898 participants (2,546 with Alzheimer’s disease [AD] and 1,211 with vascular dementia [VD]), of which, 1,031 had AFib (350 with AD; 320 with VD).
• Compared with participants without AFib, those with AFib had a 42% higher risk for all-cause dementia (adjusted hazard ratio, 1.42; P < .001) and more than double the risk for VD (aHR, 2.06; P < .001), but no significantly higher risk for AD.
• Younger age at AFib onset was associated with higher risks for all-cause dementia, AD and VD, with aHRs per 10-year decrease of 1.23, 1.27, and 1.35, respectively (P < .001 for all).
• After propensity score matching, AFib onset before age 65 years had the highest risk for all-cause dementia (aHR, 1.82; P < .001), followed by AF onset at age 65-74 years (aHR, 1.47; P < .001). Similar results were seen in AD and VD.

IN PRACTICE:

“The findings indicate that careful monitoring of cognitive function for patients with a younger [AFib] onset age, particularly those diagnosed with [AFib] before age 65 years, is important to attenuate the risk of subsequent dementia,” the authors write.

SOURCE:

The study, with first author Wenya Zhang, with the Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, was published online in JAMA Network Open.

LIMITATIONS:

Because the study was observational, a cause-effect relationship cannot be established. Despite the adjustment for many underlying confounders, residual unidentified confounders may still exist. The vast majority of participants were White. The analyses did not consider the potential impact of effective treatment of AFib on dementia risk.

DISCLOSURES:

The study had no commercial funding. The authors have declared no conflicts of interest.

A blood test that measures elevations in neurofilament light chain (NfL) levels in patients with multiple sclerosis (MS) could warn of worsening disability up to 2 years before it occurs, a new study suggests.

Rising NfL levels are a known indicator of neuroaxonal injury and correlate with MS disease activity. Levels rise in the presence of an MS relapse or MRI activity and fall following treatment with disease-modifying therapies. But the link between NfL levels and worsening disability was less understood.

This new analysis of NfL in two large MS cohorts found that elevated levels of the neuronal protein at baseline were associated with large increases in future disability risk, even in patients with no clinical relapse.

“This rising of NfL up to 2 years before signs of disability worsening represents the window when interventions may prevent worsening,” lead investigator Ahmed Abdelhak, MD, department of neurology, University of California, San Francisco, said in a press release.

The findings were published online in JAMA Neurology.
 

Early warning system?

The study included data on 1,899 patients with nearly 13,000 patient visits from two observational, long-term, real-world cohorts: the U.S.-based Expression, Proteomics, Imaging, Clinical (EPIC) study (n = 609 patients), and the Swiss Multiple Sclerosis Cohort trial (SMSC; n = 1,290 patients).

Investigators analyzed longitudinal serum NfL measurements in conjunction with clinical disability worsening, defined as 6 months or more of increased impairment as measured by the Expanded Disability Status Scale.

Researchers also assessed the temporal association between NfL measurements and the risk of increased disability and distinguished between disability with and without relapse.

Worsening disability was reported in 227 patients in the EPIC group and 435 in the SMSC trial.

Elevated NfL at baseline was associated with a 70% higher risk for worsening disability with relapse about 11 months later in the SMSC study (hazard ratio, 1.70; P = .02). In the EPIC trial, there was trend toward a 91% higher risk for worsening disability with relapse at 12.6 months, although the findings did not meet statistical significance (HR, 1.91; P = .07).

The risk of future disability progression independent of clinical relapse was 40% higher in those with high NfL at baseline in the EPIC study 12 months after baseline (HR, 1.40; P = .02) and 49% higher in the SMSC trial 21 months later (HR, 1.49; P < .001).

The early elevation of NfL levels suggests a slower degradation of nerve cells and could be a possible early warning system of future progression of disability, allowing time for interventions that could slow or even halt further disability.

“Monitoring NfL levels might be able to detect disease activity with higher sensitivity than clinical exam or conventional imaging,” senior author Jens Kuhle, MD, PhD, leader of the Swiss cohort and head of the Multiple Sclerosis Center at University Hospital and University of Basel, said in a statement.
 

Challenges for clinicians

Commenting on the findings, Robert Fox, MD, staff neurologist at the Mellen Center for MS and vice chair for research, Neurological Institute, Cleveland Clinic, said that, while there is a clinical test to measure NfL levels, incorporating that test into standard of care isn’t straightforward.

“The challenge for the practicing clinician is to translate these population-level studies to individual patient management decisions,” said Dr. Fox, who was not a part of the study.

“The published prediction curves corrected for age, sex, disease course, disease-modifying treatment, relapse within the past 90 days, and current disability status, the combination of which makes it rather challenging to calculate and interpret adjusted z score NfL levels in routine practice and then use it in clinical decision-making.”

The investigators said the study underscores the importance of NfL as an MS biomarker and “points to the existence of different windows of dynamic central nervous system pathology” that precedes worsening disability with or without relapse. But there may be a simpler explanation, Dr. Fox suggested.

“We know MRI activity occurs 5-10 times more frequently than relapses, and we know that MRI activity is associated with both NfL increases and future disability progression,” Dr. Fox said. “It is quite likely that the elevations in NfL seen here are reflective of new MRI disease activity, which frequently is seen without symptoms of an MS relapse,” he said

The study was funded by the Westridge Foundation, F. Hoffmann–La Roche, the Fishman Family, the Swiss National Research Foundation, the National Institutes of Health/National Institute of Neurological Disorders and Stroke, and the Valhalla Foundation. Dr. Abdelhak reported receiving grants from the German Multiple Sclerosis Society and the Weill Institute for Neurosciences outside the submitted work.

A blood test that measures elevations in neurofilament light chain (NfL) levels in patients with multiple sclerosis (MS) could warn of worsening disability up to 2 years before it occurs, a new study suggests.

Rising NfL levels are a known indicator of neuroaxonal injury and correlate with MS disease activity. Levels rise in the presence of an MS relapse or MRI activity and fall following treatment with disease-modifying therapies. But the link between NfL levels and worsening disability was less understood.

This new analysis of NfL in two large MS cohorts found that elevated levels of the neuronal protein at baseline were associated with large increases in future disability risk, even in patients with no clinical relapse.

“This rising of NfL up to 2 years before signs of disability worsening represents the window when interventions may prevent worsening,” lead investigator Ahmed Abdelhak, MD, department of neurology, University of California, San Francisco, said in a press release.

The findings were published online in JAMA Neurology.
 

Early warning system?

The study included data on 1,899 patients with nearly 13,000 patient visits from two observational, long-term, real-world cohorts: the U.S.-based Expression, Proteomics, Imaging, Clinical (EPIC) study (n = 609 patients), and the Swiss Multiple Sclerosis Cohort trial (SMSC; n = 1,290 patients).

Investigators analyzed longitudinal serum NfL measurements in conjunction with clinical disability worsening, defined as 6 months or more of increased impairment as measured by the Expanded Disability Status Scale.

Researchers also assessed the temporal association between NfL measurements and the risk of increased disability and distinguished between disability with and without relapse.

Worsening disability was reported in 227 patients in the EPIC group and 435 in the SMSC trial.

Elevated NfL at baseline was associated with a 70% higher risk for worsening disability with relapse about 11 months later in the SMSC study (hazard ratio, 1.70; P = .02).
