Cardiorespiratory fitness protects against declines in gait quality in patients with multiple sclerosis (MS), new research shows. Investigators found that over time, lower cardiorespiratory fitness predicts increased variability in stride time and could represent a biomarker for subtle neuromuscular decline in patients with MS.

Cardiorespiratory fitness “may exert neuroprotective effects on the central nervous system,” study investigator Syamala Buragadda, neurophysical therapist and PhD candidate, Memorial University, St. John’s, Nfld..

She reported her research at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
 

Gait changes

Gait is a complicated process involving coordination of multiple systems, but steps are almost always consistent and symmetric, said Ms. Buragadda. Patients with MS can experience subtle declines in gait quality even without relapses. Considering the neuroprotective properties of exercise, having higher fitness levels could prevent brain atrophy and protect against subtle gait changes.

Calculating stride time variability is a sensitive method to map changes in gait quality.

Ms. Buragadda, with co-investigator Michelle Ploughman, PhD, also with Memorial University, evaluated stride time variability over time in people with MS and explored whether cardiorespiratory fitness predicts stride time variability.

They recruited 49 adults with relapsing-remitting MS (63% women) and mild disability (Expanded Disability Status Scale [EDSS] score < 4; median, 2.0) from MS clinics in Canada. None required walking aids, and none had experienced relapses in the prior 3 months.

Gait quality was assessed on an instrumented walkway, and variability was measured as the coefficient of variation of stride time. Cardiorespiratory fitness was measured as maximal oxygen uptake (VO₂max) during a graded exercise test using recumbent stepper. Tests were conducted 2 years apart.

There were no significant changes in EDSS scores over the study period. However, stride time variability increased from 7.3% at baseline to 8.3% at 2 years.

Cardiorespiratory fitness at baseline significantly correlated with stride time variability 2 years later (P = .016) and was a significant predictor of stride time variability at 2 years, accounting for 10% of its variance, Ms. Buragadda reported.

Stride time variability, measured on an instrumented walkway, could be a biomarker for subtle changes to walking and balance, she said.

Limitations of the study include a convenience sample that may not represent the diversity of MS. Also, assessments were made at only two time points, and more time points would likely yield better predictive power. In addition, the lack of MRI images limits correlating structural changes with clinical observations of gait changes.
 

A buffer against disability?

In a comment, Valerie Block, physical therapist and adjunct instructor, department of physical therapy and rehabilitation science, University of California, San Francisco, and UCSF Weill Institute for Neuroscience, said the findings in this study are not surprising and align with what she has observed, subjectively, in her work.

“In the general population, cardiovascular fitness has a wide array of benefits. Depending on what means the person uses to maintain or improve cardiovascular fitness (that is, running, walking, swimming, etc.), this would have the potential for neuroplastic effects on gait – even in MS and other neurological disorders,” Ms. Block said.

Also offering perspective, Brain Sandroff, PhD, senior research scientist, Kessler Foundation, West Orange, N.J., said the study provides “more evidence on the multisystemic benefits of exercise training and having better physical fitness in persons with MS. The evidence seems to be converging more and more on this, as research groups across countries and continents are reporting on similar themes,” said Dr. Sandroff.

He noted that the findings from this study coincide with some other data that showed that premorbid physical activity is associated with reduced mobility decline over time in persons with MS.

“Collectively, the data suggest that perhaps engaging in exercise training early in the disease (or having better cardiorespiratory fitness at diagnosis) provides a buffer against disability progression over time,” Dr. Sandroff said.

He said it would be interesting to see whether “physical fitness/premorbid physical activity provides such a buffer in those who already demonstrate mobility problems.”

The study had no specific funding. Ms. Buragadda, Dr. Ploughman, Ms. Block, and Dr. Sandroff have disclosed no relevant financial relationships.

When a consumer uses a health plan provider directory to look up a physician, there’s a high probability that the entry for that doctor is incomplete or inaccurate. The Centers for Medicare & Medicaid Services would like to change that by creating a National Directory of Healthcare Providers and Services, which the agency believes would be more valuable to consumers.

In asking for public comments on whether and how it should establish the directory, CMS argues that this data repository would help patients locate physicians and could help with care coordination, health information exchange, and public health data reporting.

However, it’s not clear that such a directory would be any better than current insurance company listings or that people would use it. But a national directory could benefit physician practices by reducing their administrative work, according to observers.

In requesting public comment on the proposed national directory, CMS explains that provider organizations face “redundant and burdensome reporting requirements to multiple databases.” The directory could greatly reduce this challenge by requiring health care organizations to report provider information to a single database. Currently, physician practices have to submit these data to an average of 20 payers each, according to CMS.

“Right now, [physicians are] inundated with requests, and it takes a lot of time to update this stuff,” said David Zetter, a practice management consultant in Mechanicsburg, Pa.. “If there were one national repository of this information, that would be a good move.”

CMS envisions the National Directory as a central hub from which payers could obtain the latest provider data, which would be updated through a standardized application programming interface (API). Consequently, the insurers would no longer need to have providers submit this information to them separately.

CMS is soliciting input on what should be included in the directory. It notes that in addition to contact information, insurer directories also include a physicians’ specialties, health plan affiliations, and whether they accept new patients.

CMS’ 60-day public comment period ends Dec. 6. After that, the agency will decide what steps to take if it is decided that CMS has the legal authority to create the directory.
 

Terrible track record

In its annual reviews of health plan directories, CMS found that, from 2017 to 2022, only 47% of provider entries were complete. Only 73% of the providers could be matched to published directories. And only 28% of the provider names, addresses, and specialties in the directories matched those in the National Provider Identifier (NPI) registry.

Many of the mistakes in provider directories stem from errors made by practice staff, who have many other duties besides updating directory data. Yet an astonishing amount of time and effort is devoted to this task. A 2019 survey found that physician practices spend $2.76 billion annually on directory maintenance, or nearly $1000 per month per practice, on average.

The Council for Affordable Quality Healthcare, which conducted the survey, estimated that placing all directory data collection on a single platform could save the average practice $4,746 per year. For all practices in the United States, that works out to about $1.1 billion annually, CAQH said.
 

Pros and cons of national directory

For all the money spent on maintaining provider directories, consumers don’t use them very much. According to a 2021 Press Ganey survey, fewer than 5% of consumers seeking a primary care doctor get their information from an insurer or a benefits manager. About half search the internet first, and 24% seek a referral from a physician.

A national provider directory would be useful only if it were done right, Mr. Zetter said. Citing the inaccuracy and incompleteness of health plan directories, he said it was likely that a national directory would have similar problems. Data entered by practice staff would have to be automatically validated, perhaps through use of some kind of AI algorithm.
 

Effect on coordination of care

Mr. Zetter doubts the directory could improve care coordination, because primary care doctors usually refer patients to specialists they already know.

But Julia Adler-Milstein, PhD, professor of medicine and director of the Center for Clinical Informatics at the University of California, San Francisco, said that a national directory could improve communications among providers when patients select specialists outside of their primary care physician’s referral network.

“Especially if it’s not an established referral relationship, that’s where a national directory would be helpful, not only to locate the physicians but also to understand their preferences in how they’d like to receive information,” she said in an interview.

Dr. Adler-Milstein worries less than Mr. Zetter does about the challenge of ensuring the accuracy of data in the directory. She pointed out that the National Plan and Provider Enumeration System, which includes the NPI registry, has done a good job of validating provider name, address, and specialty information.

Dr. Adler-Milstein is more concerned about whether the proposed directory would address physician preferences as to how they wish to receive information. For example, while some physicians may prefer to be contacted directly, others may prefer or are required to communicate through their practices or health systems.
 

Efficiency in data exchange

The API used by the proposed directory would be based on the Fast Health Interoperability Resources standard that all electronic health record vendors must now include in their products. That raises the question of whether communications using contact information from the directory would be sent through a secure email system or through integrated EHR systems, Dr. Adler-Milstein said.

“I’m not sure whether the directory could support that [integration],” she said. “If it focuses on the concept of secure email exchange, that’s a relatively inefficient way of doing it,” because providers want clinical messages to pop up in their EHR workflow rather than their inboxes.

Nevertheless, Dr. Milstein-Adler added, the directory “would clearly take a lot of today’s manual work out of the system. I think organizations like UCSF would be very motivated to support the directory, knowing that people were going to a single source to find the updated information, including preferences in how we’d like people to communicate with us. There would be a lot of efficiency reasons for organizations to use this national directory.”

“We eat first with our eyes.” 

The Roman foodie Apicius is thought to have uttered those words in the 1st century A.D. Now, some 2,000 years later, scientists may be proving him right. 

Massachusetts Institute of Technology researchers have discovered a previously unknown part of the brain that lights up when we see food. Dubbed the “ventral food component,” this part resides in the brain’s visual cortex, in a region known to play a role in identifying faces, scenes, and words. 

The study, published in the journal Current Biology, involved using artificial intelligence (AI) technology to build a computer model of this part of the brain. Similar models are emerging across fields of research to simulate and study complex systems of the body. A computer model of the digestive system was recently used to determine the best body position for taking a pill. 

“The research is still cutting-edge,” says study author Meenakshi Khosla, PhD. “There’s a lot more to be done to understand whether this region is the same or different in different individuals, and how it is modulated by experience or familiarity with different kinds of foods.”

Pinpointing those differences could provide insights into how people choose what they eat, or even help us learn what drives eating disorders, Dr. Khosla says. 

Part of what makes this study unique was the researchers’ approach, dubbed “hypothesis neutral.” Instead of setting out to prove or disprove a firm hypothesis, they simply started exploring the data to see what they could find. The goal: To go beyond “the idiosyncratic hypotheses scientists have already thought to test,” the paper says. So, they began sifting through a public database called the Natural Scenes Dataset, an inventory of brain scans from eight volunteers viewing 56,720 images. 

As expected, the software analyzing the dataset spotted brain regions already known to be triggered by images of faces, bodies, words, and scenes. But to the researchers’ surprise, the analysis also revealed a previously unknown part of the brain that seemed to be responding to images of food. 

“Our first reaction was, ‘That’s cute and all, but it can’t possibly be true,’ ” Dr. Khosla says. 

To confirm their discovery, the researchers used the data to train a computer model of this part of the brain, a process that takes less than an hour. Then they fed the model more than 1.2 million new images. 

Sure enough, the model lit up in response to food. Color didn’t matter – even black-and-white food images triggered it, though not as strongly as color ones. And the model could tell the difference between food and objects that looked like food: a banana versus a crescent moon, or a blueberry muffin versus a puppy with a muffin-like face. 

From the human data, the researchers found that some people responded slightly more to processed foods like pizza than unprocessed foods like apples. They hope to explore how other things, such as liking or disliking a food, may affect a person’s response to that food. 

This technology could open up other areas of research as well. Dr. Khosla hopes to use it to explore how the brain responds to social cues like body language and facial expressions. 

For now, Dr. Khosla has already begun to verify the computer model in real people by scanning the brains of a new set of volunteers. “We collected pilot data in a few subjects recently and were able to localize this component,” she says.

The goal: To go beyond “the idiosyncratic hypotheses scientists have already thought to test,” the paper says. So, they began sifting through a public database called the Natural Scenes Dataset, an inventory of brain scans from eight volunteers viewing 56,720 images. 

As expected, the software analyzing the dataset spotted brain regions already known to be triggered by images of faces, bodies, words, and scenes. But to the researchers’ surprise, the analysis also revealed a previously unknown part of the brain that seemed to be responding to images of food. 

“Our first reaction was, ‘That’s cute and all, but it can’t possibly be true,’ ” Dr. Khosla says. 

To confirm their discovery, the researchers used the data to train a computer model of this part of the brain, a process that takes less than an hour. Then they fed the model more than 1.2 million new images. 

Sure enough, the model lit up in response to food. Color didn’t matter – even black-and-white food images triggered it, though not as strongly as color ones. And the model could tell the difference between food and objects that looked like food: a banana versus a crescent moon, or a blueberry muffin versus a puppy with a muffin-like face. 

From the human data, the researchers found that some people responded slightly more to processed foods like pizza than unprocessed foods like apples. They hope to explore how other things, such as liking or disliking a food, may affect a person’s response to that food. 

This technology could open up other areas of research as well. Dr. Khosla hopes to use it to explore how the brain responds to social cues like body language and facial expressions. 

For now, Dr. Khosla has already begun to verify the computer model in real people by scanning the brains of a new set of volunteers. “We collected pilot data in a few subjects recently and were able to localize this component,” she says.

“We eat first with our eyes.” 

The Roman foodie Apicius is thought to have uttered those words in the 1st century A.D. Now, some 2,000 years later, scientists may be proving him right. 

Massachusetts Institute of Technology researchers have discovered a previously unknown part of the brain that lights up when we see food. Dubbed the “ventral food component,” this part resides in the brain’s visual cortex, in a region known to play a role in identifying faces, scenes, and words. 

The study, published in the journal Current Biology, involved using artificial intelligence (AI) technology to build a computer model of this part of the brain. Similar models are emerging across fields of research to simulate and study complex systems of the body. A computer model of the digestive system was recently used to determine the best body position for taking a pill. 

“The research is still cutting-edge,” says study author Meenakshi Khosla, PhD. “There’s a lot more to be done to understand whether this region is the same or different in different individuals, and how it is modulated by experience or familiarity with different kinds of foods.”

Pinpointing those differences could provide insights into how people choose what they eat, or even help us learn what drives eating disorders, Dr. Khosla says.

Masks can be scary on Halloween, but more so when they come with scrubs, scalpels, and God complexes. In March, Medscape readers chose their favorite characters and performers in the Hollywood health care system. As a Halloween treat, we follow up with a dozen of our favorite Evil Doctors from a deep bench (and no, Dr Evil didn’t go to medical school; neither did Dr No, for that matter). Before you see these folks who’d rather haunt than heal, we urge you to seek a second opinion.

George Harris (Richard Widmark, “Coma,” 1978)

“Medicine is now a great social force,” says Dr. George Harris (Richard Widmark), chief of surgery at Boston Memorial. Because the public trusts doctors, “we’ll make the hard decisions” – like choosing which young, healthy patients to put into an irreversible coma to harvest their organs. Harris’ audience of one here is Dr. Susan Wheeler (Genevieve Bujold), the upstart who has uncovered his plot, and whom Harris has just drugged to prepare her as his next unintentional donor. “Coma” was based on a bestseller by Robin Cook and directed by Michael Crichton, who left Harvard Medical School for a career in popular books and films, including “The Andromeda Strain” and “Jurassic Park.” Although Dr. Harris starts out as a reassuring friend and mentor to Dr. Wheeler, older moviegoers won’t forget that he launched to stardom by tossing a woman in a wheelchair down the stairs in 1947’s “Kiss of Death.”
 

Christian Szell (Laurence Olivier, “Marathon Man,” 1976)

He may look harmless, but Christian Szell (Laurence Olivier) is a sadist with a secret, a stash, and throat-slitting skills. Szell, a dentist known as the White Angel of Auschwitz for his war crimes, stops at nothing to protect the diamonds he stole from his victims in the camps. In one of Hollywood’s most infamous torture scenes, Szell tries to extract information from Babe Levy (Dustin Hoffman), an innocent grad student, plying the tools of his trade. When Szell asks, “Is it safe?” he’s not curious about whether Babe’s insurance covers anesthesia.

Orin Scrivello (Steve Martin, “Little Shop of Horrors,” 1986)

Sticking with deranged dentists, Orin Scrivello, DDS, (Steve Martin) sings and dances his way into your nightmares buoyed by copious helpings of nitrous oxide. Orin’s too-encouraging momma told him to parlay his sadistic tendencies into a career “where people will pay you to be inhumane.” Sonny listened. Moviegoers were treated to screeching sound effects of a tooth getting yanked during an Elvis-like musical number shot in part from inside a patient’s mouth. Martin makes a creepy scene more fun than a long, slow root canal.

Henry Frankenstein (Colin Clive, “Frankenstein,” 1931)

His alarming need for fresh corpses forced Henry Frankenstein (Colin Clive) to leave medical school and experiment solo in a castle. He insists to his betrothed that he hasn’t gone mad when she arrives as  he is bringing a dead body back to life during a raging lightning storm. When she and Henry’s mentor, Dr Waldman, witness him succeed, Waldman warns Henry that the former owner of the purloined brain was a notorious criminal. When Henry exclaims: “It’s alive, it’s alive !” little did he know that he created the face (Boris Karloff) that would launch a thousand sequels, a spectacular satire, and untold Halloween masks.

Dr. Gogol (Peter Lorre, “Mad Love,” 1935)

A few years after playing doctor Frankenstein, Colin Clive became the patient of a mad medic himself. A concert pianist whose hands have been mangled in a train wreck, Clive’s wife turns to Dr. Gogol (Peter Lorre, in his Hollywood debut), who promises to surgically reattach the musician’s hands. Unfortunately, Gogol is so obsessed with the wife, a star of gory stage shows, that he has created a wax figure of her. He schemes to win her in the flesh by attaching a murderer’s hands to Clive, then frame him for committing murder with those hands. Gogol utters the madman’s lament: “I have conquered science. Why can’t I conquer love?” A modern remake would surely have him asking, “Why do they swipe left?

Hannibal Lecter (Anthony Hopkins, “Silence of the Lambs,” 1991)

The FBI, hunting for a serial killer, sends trainee Clarice Starling (Jodie Foster) to seek insight into the murderer from the imprisoned Dr. Hannibal Lecter (Anthony Hopkins), a brilliant psychiatrist with a penchant for murder — and a taste for the flesh of his victims. Lecter proves to be a menace from their first meeting; the bars and glass surrounding his cell offer Clarice no protection from his gaze and ability to read her mind. In his own way, the urbane, pathologically charming Lecter takes a shine to Clarice, helping with the case while embarking on another murderous spree against men who recently wronged her. When he escapes, his plans do not include dinner with – or of – Clarice, but others, well, they’re not so lucky.

Henry Jekyll (Fredric March, “Dr. Jekyll and Mr. Hyde,” 1931)

Henry Jekyll (Fredric March) is a jumble of personalities. By day, he’s a kindly doctor in Victorian London with an American accent. But he is so determined to split good and evil personalities that he devises a potion to outsource his id. As he watches himself morph into Mr. Hyde – a hairy, cone-headed dude in serious need of an orthodontist – he exclaims, “Free! Free at last!” Free, that is, for his simian side to engage in debauchery, abuse, self-hatred, intimations of rape, and ultimately murder – all of which are explored in this pre-Code film, the first talkie version of Robert Louis Stevenson’s story.

Dr. Moreau (Charles Laughton, “Island of Lost Souls,” 1932)

“Strange-looking natives you have here,” shipwreck victim Edward Parker (Richard Arlen) tells his host, the white-suited, whip-wielding Dr Moreau. Before long, we learn that Moreau’s evil veterinary talents  have created an island population of human/beast hybrids who are forced to follow his laws – especially one forbidding them from eating meat or walking on all fours. Lawbreakers get taken to the House of Pain, a medical setting which, as its name suggests, lacks adequate analgesia. Burt Lancaster and Marlon Brando took on the Moreau role in later versions, but Laughton is the creepiest when he asks, “Do you know what it means to feel like God?” The film was banned for years in Britain, and H.G. Wells despised this take on his antivivisection tale.

Charles Nichols (Jeroen Krabbé, “The Fugitive,” 1993)

Richard Kimble, a Chicago vascular surgeon, arrives home to find that a man just brutally murdered his loving wife. The killer escapes, and Kimble falls into the frame-up. Convicted for the murder and headed to prison, Kimble breaks free in an epic escape scene. He spends the rest of the movie all but giving his right arm to find the murderer, while being pursued by a dogged U.S. Marshal played with gusto by Tommy Lee Jones. Kimble eventually discovers that his colleague, Dr. Charles Nichols (Jeroen Krabbé), is not quite the best friend a man could have – or the most ethical of clinical investigators.

Elliot and Beverly Mantle (Jeremy Irons, “Dead Ringers,” 1988)

“You’ve got to try the movie star,” fertility specialist Elliot Mantle (Jeremy Irons) implores to his identical but meek twin brother, Beverly (also Jeremy Irons), talking about an actress-patient (Genevieve Bujold) as if she were a menu item. Beverly shares a practice with Elliot, along with a soul and an easily satisfied drug addiction. Beverly is unaware that Elliot seduces patients before passing them off to his brother, including the actress. Beverly is in love with the actress, which upsets the equilibrium of their shared soul. He aims to fix this, but not without some trauma involving freakish and unsanitary operating implements.

Dean Armitage (Bradley Whitford, “Get Out,” 2017)

Neurosurgeon Dean Armitage (Bradley Whitford) was such a fan of President Obama that he would have voted for him a third time if he could. At least, that’s how he portrays himself to Chris (Daniel Kaluuya), an African American photographer and the new boyfriend of Armitage’s White daughter. The Armitage estate has plenty of people of color – on staff, anyway – but Chris finds them odd and distant. It turns out that a gathering of rich White people is in fact an auction for his eyesight. Horror ensues. The main message from this film is not unlike that of Russian operatives who fall out of favor with the Kremlin: Don’t drink the tea.

High-efficacy therapies for multiple sclerosis (MS) have improved disease outcomes for many patients, but physicians are uncertain when to use them. Despite better long-term disease outcomes, there are concerns over long-term safety, and some physicians and patients remain wary of these medications.

High-efficacy therapies were the subject of a session at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). Key topics included patient selection, timing of escalation to high-efficacy therapies, and initial use of high-efficacy therapies. The session produced a compelling message, according to moderator Patricia Coyle, MD. “I think [the speakers provided] accumulating data that this is a smart thing to do: Use high-efficacy therapies early to get the maximum bang for the buck,” Dr. Coyle said in an interview. She is professor of neurology and director of the MS Comprehensive Care Center at Stony Brook (N.Y.) University.
 

Consider baseline characteristics

In the first talk, Xavier Montalban, MD, PhD, noted that a statement from the ECTRIMS/EAN (European Academy of Neurology) guideline update in 2021 said that a high-efficacy disease-modifying therapy (DMT) should be considered early in the disease course. A key question is whether any baseline characteristics can be used to select patients, and studies have shown worse prognosis with older age, male sex, low levels of vitamin D, and smoking status, among various other factors.

He presented subgroup analyses from trials of fingolimod and ozanimod, which showed that the drugs did not work as well in patients with poor prognostic factors such as an Expanded Disability Status Scale (EDSS) score of 4 or above and age over 40 years. Lower doses also tend to have less efficacy in males. “If you have [a patient with] bad baseline prognostic factors, you need high-efficacy medication at the right dose, because a lower dose will not work well. It is the same phenomenon for age,” Dr. Montalban said in his talk. On the other hand, he showed the results of a study of ofatumumab and ocrelizumab, both of which showed high efficacy even in patients with poor prognostic factors.

Among patients with secondary progressive MS, clinical or MRI evidence of inflammatory activity is the only poor prognostic factor that appears to be a good predictor of treatment response.

Dr. Montalban also addressed the timing of intervention with DMTs. A study from his group prospectively followed 1,015 patients treated with DMTs. “Interestingly, what we observed is that patients who were treated with DMTs just after the first attack did better than those who were treated after the second attack, and you have to take into consideration that we treat those patients after the first attack, those who had the worst prognostic factors, so treatment was very effective in that sense,” said Dr. Montalban, director of the Multiple Sclerosis Centre of Catalonia at Vall d’Hebron University Hospital in Barcelona.

In the second presentation, Dalia Rotstein, MD, discussed how to incorporate prognostic factors when switching a patient to high-efficacy therapies as a result of new disease activity while on another therapy.

Patients with favorable prognostic factors at baseline may be started out on immunomodulatory therapy. “Essentially, we want to match the intensity of the therapy to the intensity of the disease of the patient in front of us,” Dr. Rotstein said in her talk. Nevertheless, the course of MS is unpredictable, and the first year or two of immunomodulatory therapy can give physicians clues about the longer-term course of the disease. “We need to observe closely for disease activity in the first year, but even up to 2 years on therapy to determine a need for early escalation,” said Dr. Rotstein, assistant professor of medicine at University of Toronto.

For switching to high-efficacy therapies, any relapse, disability progression, or an EDSS change of 1 point or more could be a consideration. MRI indicators are more controversial, but one to three new T2 lesions also could prompt a switch.

Serum neural filament light chain (sNFL) is a useful biomarker for monitoring disease activity as it correlates well with new disease activity within the next year. It can be monitored every 3-4 months and adjusted for clinical factors and monitored for changing levels. A concerning finding can be followed up with an MRI or in-person visit.

When switching to a high-efficacy therapy, it’s important to administer any vaccines well in advance to ensure a good immune response.

When it comes to a washout period, physicians need to consider both the risk of immunosuppression and breakthrough disease activity. “But in general, we’ve observed that we can minimize the duration of the washout when stopping initial immunomodulator therapy to reduce the risk of breakthrough disease activity. We need to pay particular attention to the risk of rebound activity with longer washouts after stopping sphingosine-1 phosphate (S1P) receptor modulators because the rebound activity can be devastating,” said Dr. Rotstein.

A study of timing of relapses after fingolimod washout, carried out by Dr. Rotstein’s group, found a stark signal. “We observed that when the washout after fingolimod discontinuation was 30 days or more, there is a very high risk of early relapse,” she said.
 

The case for induction therapy

In the third talk, Gavin Giovannoni, MBBCh, PhD, discussed “flipping the pyramid” – that is, starting patients off immediately with high-efficacy therapies rather than waiting until they progress on other therapies. He likened such a decision to a gambler, because MS patients on less-effective therapy can suffer irreversible, long-term physical consequences, as well as social consequences such as unemployment due to cognitive effects.

“We always tend to put up a graph about the risks and benefits of a specific treatment, and we forget about the risks of untreated or undertreated MS. Keep that in mind when making decisions about high-efficacy therapies,” said Dr. Giovannoni, professor of neurology at Queen Mary University of London.

About 80% of patients on tier 1, or low-efficacy therapies, will have breakthrough activity on MRI within 4 years. Moving up a tier gets to about a 60% rate of breakthrough activity. High-efficacy therapies attain an efficacy of about 80% at 6 months. “If you have MS, you’ve got to realize that if you had to roll the dice, which tier would you want to be in? By putting all of them [on high-efficacy therapies], you’re going to get the majority responding and a few of them will break through,” said Dr. Giovannoni.

He presented some real-world evidence to back up the argument: A study comparing outcomes in Sweden and Denmark, which have similar demographics. In Denmark, 7.6% of patients with MS received high-efficacy therapies initially, while in Sweden the proportion was 34.5%. Patients with MS treated in Sweden had a 29% lower probability of progressing to disability (P = .004) and there were 22% fewer discontinuations of DMTs (P < .001). Since that study, the proportion of patients receiving high-efficacy therapies to begin with is closer to 70%. “This is compelling evidence that you want to be on a [high-efficacy therapy] early. If I had MS, I would want to live in Sweden,” said Dr. Giovannoni.

Historical treatments focused on reducing relapses, and more recently on eliminating evidence of inflammatory disease. He said that physicians are prioritizing brain volume loss to improve long-term outcomes in MS, and some are studying long-term disability. “We know that brain volume loss in MS is a prognostic sign both at baseline and at follow-up. It predicts poor outcome, poor cognition and employment, poor quality of life, et cetera,” said Dr. Giovannoni.

He cited data from studies of alemtuzumab that showed a significant reduction in brain volume loss. “The rate is about 0.2% per annum, which is kind of getting into the normal range for age-matched controls. Those people who were started off on interferons in the study lost a lot of brain volume in those first 2 years, and that’s irreversible,” said Dr. Giovannoni.

He pointed out that studies of hematopoietic stem cell therapy showed similar brain-volume outcomes. “So flipping the pyramid with the two most highly effective therapies almost normalizes brain volume loss in people with MS,” said Dr. Giovannoni.

There is also evidence in other autoimmune diseases that early use of high-efficacy therapies improves outcomes. More aggressive therapy in rheumatoid arthritis has reduced joint replacements by 90%.

“I think you really, really need to give your patients the opportunity of flipping the pyramid. You shouldn’t decide that for them,” said Dr. Giovannoni.

High-efficacy therapies for multiple sclerosis (MS) have improved disease outcomes for many patients, but physicians are uncertain when to use them. Despite better long-term disease outcomes, there are concerns over long-term safety, and some physicians and patients remain wary of these medications.

High-efficacy therapies were the subject of a session at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). Key topics included patient selection, timing of escalation to high-efficacy therapies, and initial use of high-efficacy therapies. The session produced a compelling message, according to moderator Patricia Coyle, MD. “I think [the speakers provided] accumulating data that this is a smart thing to do: Use high-efficacy therapies early to get the maximum bang for the buck,” Dr. Coyle said in an interview. She is professor of neurology and director of the MS Comprehensive Care Center at Stony Brook (N.Y.) University.
 

Consider baseline characteristics

In the first talk, Xavier Montalban, MD, PhD, noted that a statement from the ECTRIMS/EAN (European Academy of Neurology) guideline update in 2021 said that a high-efficacy disease-modifying therapy (DMT) should be considered early in the disease course. A key question is whether any baseline characteristics can be used to select patients, and studies have shown worse prognosis with older age, male sex, low levels of vitamin D, and smoking status, among various other factors.

He presented subgroup analyses from trials of fingolimod and ozanimod, which showed that the drugs did not work as well in patients with poor prognostic factors such as an Expanded Disability Status Scale (EDSS) score of 4 or above and age over 40 years. Lower doses also tend to have less efficacy in males. “If you have [a patient with] bad baseline prognostic factors, you need high-efficacy medication at the right dose, because a lower dose will not work well. It is the same phenomenon for age,” Dr. Montalban said in his talk. On the other hand, he showed the results of a study of ofatumumab and ocrelizumab, both of which showed high efficacy even in patients with poor prognostic factors.

Among patients with secondary progressive MS, clinical or MRI evidence of inflammatory activity is the only poor prognostic factor that appears to be a good predictor of treatment response.

Dr. Montalban also addressed the timing of intervention with DMTs. A study from his group prospectively followed 1,015 patients treated with DMTs. “Interestingly, what we observed is that patients who were treated with DMTs just after the first attack did better than those who were treated after the second attack, and you have to take into consideration that we treat those patients after the first attack, those who had the worst prognostic factors, so treatment was very effective in that sense,” said Dr. Montalban, director of the Multiple Sclerosis Centre of Catalonia at Vall d’Hebron University Hospital in Barcelona.

CINCINNATI – Sickle cell disease is well known for its associated anemia, but patients experience a range of other complications as well. These include vision and kidney problems, delayed growth, susceptibility to infection, and pain.

Another issue, not always as well recognized, is a considerably heightened risk for childhood stroke. “Children with sickle cell disease have 100 times the risk of stroke as other children without sickle cell disease, and there’s also an elevated risk of five times the general population in adults with sickle cell disease,” said Lori Jordan, MD, PhD, in an interview.

At the 2022 annual meeting of the Child Neurology Society, Dr. Jordan spoke about stroke as a complication of sickle cell disease, and the role that neurologists can play in preventing primary or secondary strokes. “At least in children, studies have shown that if we screen and identify patients who are at highest risk of stroke, there are primary prevention therapies – usually implemented by hematologists, but that neurologists often are involved with – both monitoring for cognitive effects of silent cerebral infarct and also with treating patients who unfortunately still have an acute stroke,” said Dr. Jordan, who is an associate professor of pediatrics, neurology, and radiology at Vanderbilt University Medical Center, Nashville, Tenn. She also is director of the pediatric stroke program at Vanderbilt.
 

Time is of the essence

“In general, stroke in children is rare, but it’s more common in sickle cell disease, so it’s really important for providers to know that stroke risk is higher in those patients, particularly in those children, and then identify it and treat it earlier. Time is of the essence, and if we can give them the same therapeutics that we give the general stroke population, then time really becomes a factor, so it’s important that people know that it’s an issue for this population,” said Eboni Lance, MD, PhD, who coordinated the session where Dr. Jordan spoke.

Sickle cell disease is caused by a double mutation in the gene encoding the hemoglobin gene, producing the altered sickle hemoglobin (hemoglobin S). The change causes the hemoglobin proteins to tend to stick to one another, which can lead red blood cells to adopt a sickle-like shape. The sickle-shaped blood cells in turn have a tendency to aggregate and can block blood flow or lead to endothelial injury. Symptoms of stroke in children can include hemiparesis, aphasia, and seizure, but they can also be silent.

If no preventive is employed, one in nine with sickle cell disease will experience a stroke by the age of 19. Cerebrovascular symptoms are the most frequent debilitating complication of the condition. Nearly 40% of patients with sickle cell disease will have a silent cerebral infarct by age 18, as will 50% by age 30. Silent strokes have been associated with worse educational attainment and a greater need for educational special services.

Factors contributing to stroke in children with sickle cell disease include anemia and a low blood oxygen count, reduced oxygen affinity of hemoglobin variant, and cerebral vasculopathy. An estimated 10%-15% of young adults with sickle cell disease have severe intracranial stenosis.
 

Primary and secondary stroke prevention strategies

The dire consequences of stroke in this patient population underline the importance of primary stroke prevention, which requires the use of transcranial Doppler (TCD) ultrasound. It has been validated as a tool to screen for initial stroke risk in children with no history of stroke. High velocity measured on TCD indicates a narrowed blood vessel or elevated blood that is compensating for anemia. It adds up to a “struggling brain,” said Dr. Jordan, during her talk. If the TCD ultrasound velocity is greater than 200 cm/sec (or 170 cm/sec, depending on nonimaging versus imaging TCD), the TWiTCH trial showed that seven monthly transfusions is the number needed to treat to prevent one stroke. After 1 year, patients can be switched from transfusions to hydroxyurea if the patient has no significant intracranial stenosis. Hydroxyurea boosts both fetal and total hemoglobin, and also counters inflammation.

Following an acute stroke or transient ischemic attack, patients should receive a transfusion within 2 hours of presenting in the health care setting. American Society of Hematology guidelines recommend exchange transfusion rather than a simple transfusion. A simple transfusion can be initiated if an exchange transfusion is not available within 2 hours and hemoglobin values are less than 8.5 g/dL, to be followed by performance of exchange transfusion when available.

For chronic secondary stroke prevention, transfusions should be performed approximately monthly with the goal of maintaining hemoglobin above 9 g/dL at all times, as well as suppressing hemoglobin S levels to 30% or less of total hemoglobin.

Sudden, severe headache is a potential harbinger of complications like aneurysm, which occurs 10-fold more often among patients with sickle cell disease than the general population. It could also indicate increased intracranial pressure or cerebral venous sinus thrombosis.

Treatment of acute headache in sickle cell disease should avoid use of triptans, since vasoconstriction can counter the increased cerebral blood flow that compensates for anemia. Gabapentin and amitriptyline are good treatment choices.

New-onset seizures are a potential sign of stroke or posterior reversible leukoencephalopathy (PRES) in patients with sickle cell disease. Urgent MRI should be considered for all new-onset seizures. If blood pressure is high, PRES may be present. Seizures may also be an indicator of a previous brain injury.

Dr. Jordan has no relevant financial disclosures. Dr. Lance has served on an advisory board for Novartis.

Sudden, severe headache is a potential harbinger of complications like aneurysm, which occurs 10-fold more often among patients with sickle cell disease than the general population. It could also indicate increased intracranial pressure or cerebral venous sinus thrombosis.

Treatment of acute headache in sickle cell disease should avoid use of triptans, since vasoconstriction can counter the increased cerebral blood flow that compensates for anemia. Gabapentin and amitriptyline are good treatment choices.

New-onset seizures are a potential sign of stroke or posterior reversible leukoencephalopathy (PRES) in patients with sickle cell disease. Urgent MRI should be considered for all new-onset seizures. If blood pressure is high, PRES may be present. Seizures may also be an indicator of a previous brain injury.

CINCINNATI – Sickle cell disease is well known for its associated anemia, but patients experience a range of other complications as well. These include vision and kidney problems, delayed growth, susceptibility to infection, and pain.

Another issue, not always as well recognized, is a considerably heightened risk for childhood stroke. “Children with sickle cell disease have 100 times the risk of stroke as other children without sickle cell disease, and there’s also an elevated risk of five times the general population in adults with sickle cell disease,” said Lori Jordan, MD, PhD, in an interview.

At the 2022 annual meeting of the Child Neurology Society, Dr. Jordan spoke about stroke as a complication of sickle cell disease, and the role that neurologists can play in preventing primary or secondary strokes. “At least in children, studies have shown that if we screen and identify patients who are at highest risk of stroke, there are primary prevention therapies – usually implemented by hematologists, but that neurologists often are involved with – both monitoring for cognitive effects of silent cerebral infarct and also with treating patients who unfortunately still have an acute stroke,” said Dr. Jordan, who is an associate professor of pediatrics, neurology, and radiology at Vanderbilt University Medical Center, Nashville, Tenn. She also is director of the pediatric stroke program at Vanderbilt.
 

Time is of the essence

“In general, stroke in children is rare, but it’s more common in sickle cell disease, so it’s really important for providers to know that stroke risk is higher in those patients, particularly in those children, and then identify it and treat it earlier. Time is of the essence, and if we can give them the same therapeutics that we give the general stroke population, then time really becomes a factor, so it’s important that people know that it’s an issue for this population,” said Eboni Lance, MD, PhD, who coordinated the session where Dr. Jordan spoke.

Sickle cell disease is caused by a double mutation in the gene encoding the hemoglobin gene, producing the altered sickle hemoglobin (hemoglobin S). The change causes the hemoglobin proteins to tend to stick to one another, which can lead red blood cells to adopt a sickle-like shape. The sickle-shaped blood cells in turn have a tendency to aggregate and can block blood flow or lead to endothelial injury. Symptoms of stroke in children can include hemiparesis, aphasia, and seizure, but they can also be silent.

If no preventive is employed, one in nine with sickle cell disease will experience a stroke by the age of 19. Cerebrovascular symptoms are the most frequent debilitating complication of the condition. Nearly 40% of patients with sickle cell disease will have a silent cerebral infarct by age 18, as will 50% by age 30. Silent strokes have been associated with worse educational attainment and a greater need for educational special services.

Factors contributing to stroke in children with sickle cell disease include anemia and a low blood oxygen count, reduced oxygen affinity of hemoglobin variant, and cerebral vasculopathy. An estimated 10%-15% of young adults with sickle cell disease have severe intracranial stenosis.
 

Primary and secondary stroke prevention strategies

The dire consequences of stroke in this patient population underline the importance of primary stroke prevention, which requires the use of transcranial Doppler (TCD) ultrasound. It has been validated as a tool to screen for initial stroke risk in children with no history of stroke. High velocity measured on TCD indicates a narrowed blood vessel or elevated blood that is compensating for anemia. It adds up to a “struggling brain,” said Dr. Jordan, during her talk. If the TCD ultrasound velocity is greater than 200 cm/sec (or 170 cm/sec, depending on nonimaging versus imaging TCD), the TWiTCH trial showed that seven monthly transfusions is the number needed to treat to prevent one stroke. After 1 year, patients can be switched from transfusions to hydroxyurea if the patient has no significant intracranial stenosis. Hydroxyurea boosts both fetal and total hemoglobin, and also counters inflammation.

Following an acute stroke or transient ischemic attack, patients should receive a transfusion within 2 hours of presenting in the health care setting. American Society of Hematology guidelines recommend exchange transfusion rather than a simple transfusion. A simple transfusion can be initiated if an exchange transfusion is not available within 2 hours and hemoglobin values are less than 8.5 g/dL, to be followed by performance of exchange transfusion when available.

For chronic secondary stroke prevention, transfusions should be performed approximately monthly with the goal of maintaining hemoglobin above 9 g/dL at all times, as well as suppressing hemoglobin S levels to 30% or less of total hemoglobin.

Sudden, severe headache is a potential harbinger of complications like aneurysm, which occurs 10-fold more often among patients with sickle cell disease than the general population. It could also indicate increased intracranial pressure or cerebral venous sinus thrombosis.

New-onset seizures are a potential sign of stroke or posterior reversible leukoencephalopathy (PRES) in patients with sickle cell disease. Urgent MRI should be considered for all new-onset seizures. If blood pressure is high, PRES may be present. Seizures may also be an indicator of a previous brain injury.

Doctor, doctor, gimme the news. I got a bad case of misidentifying you

There are a lot of medical specialties out there. A lot. Everything from allergists to urologists, with something like 150 subspecialties grouped in among the larger specialties. Can you name every one? Do you know what they do?

The point is, telling a patient or anyone in the general public that you’re an ophthalmologist may not be as helpful as you might think, if a recent study is to be believed. In a survey of 204 adults, conducted at the Minnesota State Fair of all places, researchers asked volunteers to define 14 different specialties, as well as five medical seniority titles.

Minerva Studio/ThinkStock

The results were less than stellar. While more than 90% of people correctly defined what cardiologists and dermatologists do, 6 of the other 12 specialists were correctly identified by less than half of those surveyed. Nephrology was at the bottom, correctly identified by just 20% of the fair-attending public, followed by internists (21%), intensivists (29%), hospitalists (31%), pulmonologists (43%), and neonatologists at 48%. The hospitalists are particularly concerning. They’re doctors, but in hospitals. How hard is that? (Yes, it’s obviously more complicated than that, but still.)

The general public didn’t fare much better when it came to correctly lining up the order of progression from medical student to attending. Just 12% managed to place all five in the correct order of med student, intern, senior resident, fellow, then attending, with senior resident proving especially troublesome. More than 40% put senior resident at the end, compared with 27% for attending. Which does make a certain amount of sense, since it has senior in the name.

While the results speak for themselves – maybe elaborate on what the heck your fancy title actually means – it’s too bad the researchers didn’t throw in something really tricky. If two-thirds of the population can’t identify a hospitalist, just imagine how many people would misidentify an otolaryngologist.
 

Beach-to-table sand could fight obesity

People are always looking for the new weight loss solution. Whether it’s to just look good in a new pair of jeans or reduce the risk of cardiovascular disease, there are millions of diets and exercise routines out here. We’re here to tell you that the next new therapy to reduce fat comes from a very unsuspecting place: Sand.

David Stanley

Like sand from the beach and desert, sand? Well, yes and no.

The research involved engineered porous silica particles made from sand that are designed to have a high surface area. Investigators used a two-step GI model in which gastric digestion was modeled for 30 minutes, followed by a 60-minute intestinal phase, to show that the porous silica particles helped prevent fat and sugar adsorption within the GI tract.

By mimicking the gastrointestinal environment during digestion of a high-fat, high-carb meal, the researchers found that the porous silica created an “anti-obesity effect” by restricting the adsorption of those fats and carbohydrates.

Okay, but how is that on the tummy? Much gentler on the stomach than a drug such as orlistat, said senior researcher Paul Joyce, PhD, of the University of South Australia, Adelaide, who noted the lack of effective therapies without side effects, such as bloating, diarrhea, and abdominal pain, that deter people from treatment.

Obesity affects over 1.9 billion people worldwide, so the researchers think this could be a breakthrough. Reducing obesity may be one of the most preventable ways to reduce the risk of type 2 diabetes, heart disease, and other weight-related chronic conditions. A treatment solution this simple could be the answer to this global health crisis.

Who would have thought the solution would be as simple as sand? But how would the sand get in our stomachs? Do we sprinkle it on our food? Mix it in during cooking? Or will the sand come in pill form? We sure hope it’s that third one.
 

I am Reliebo. I am here to help you

Halloween is almost here, and the LOTME staff has been trying to make the office look as scary as possible: Headless vampires, ghost clowns, Ted Cruz, gray tombstones, pink hearts, green clovers, red balloons. Wait a second, those last three are Lucky Charms marshmallows, aren’t they? We’ll use those some other time.

University of Tsukuba

What are we not using to decorate? Well, besides marshmallows from cereal, we’re not using Reliebo. That’s what we’re not using. Reliebo is a cute little fuzzy robot, and is not at all scary. Reliebo was designed to be the opposite of scary. Reliebo “may reduce fear as well as alleviate the perception of pain during medical treatments, including vaccinations,” senior author Fumihide Tanaka, PhD, of the University of Tsukuba (Japan) said in a written statement.

The soft, fur-covered robot contains small airbags that can inflate in response to hand movements. When study participants were subjected to a moderate heat stimulus on one arm, those who held the robot with the other arm experienced less pain than those who did not have a Reliebo.

The results also were encouraging when Dr. Tanaka and associates measured the levels of oxytocin and cortisol (biomarkers for stress) from the subjects’ saliva samples and evaluated their fear of injections and their psychological state before and after the experiments.

After looking at that photo of Reliebo for a while, though, we have to admit that we’re having a bit of a rethink about its cuteness. Is it cute, or weird-looking? An office full of fuzzy little inflating robots just could be seriously creepy. Please don’t tell the rest of the staff about this. We want to surprise them on Monday.

A 67-year-old man asks about what he can do to prevent dementia. He reports his mother had dementia, and he wants to do everything he can to prevent it. Which of the following has evidence of benefit?

A) Thiamine

B) Vitamin E

C) Multivitamin (MV)

D) Keto diet

E) Red wine
 

FDA-approved therapies for dementia

To date the actual therapies for dementia have been disappointing. Donepezil, the most prescribed medication for the treatment of dementia has a number-needed-to treat (NNT) over 17, and causes frequent side effects. Aducanumab was recently approved by the Food and Drug Administration for the treatment of Alzheimer’s disease (AD), but controversy has arisen, as the clinical results were modest, and the price tag will be large – estimated at $30,000-$50,000/year.

Preventive options that may decrease the likelihood of dementia

Patients often ask the question stated above. Regarding how to respond to that question, choice C, MV, has some recent evidence of benefit. Baker and colleagues studied the effect of cocoa extract and multivitamins on cognitive function in the COSMOS-Mind trial.¹ A total of 2,262 people were enrolled, and over 90% completed baseline and at least one annual cognitive assessment. Cocoa extract had no impact on global cognition (confidence interval [CI], –.02-.08, P = .28), but MV supplementation did have a statistically significant impact on global cognition (CI, .02-.12, P less than .007).

Vitamin E has been enthusiastically endorsed in the past as a treatment to prevent cognitive decline. The most recent Cochrane review on vitamin E concluded there was no evidence that the alpha-tocopherol form of vitamin E given to people with MCI prevents progression to dementia, or that it improves cognitive function in people with MCI or dementia due to AD.²

Exercise has long been a mainstay of our advice to patients as something they can do to help prevent dementia. Yu and colleagues did a meta-analysis of almost 400 randomized controlled trials and observational studies to grade the evidence on different interventions.³ They gave exercise a grade B for evidence of benefit.

A recent study addressed this issue, and I think it is helpful on quantifying how much exercise is needed. Del Pozo Cruz and colleagues did a prospective population-based cohort study of 78,000 adults aged 40-79, with an average of 6.9 years of follow up.⁴ The optimal step count was 9,826 steps (hazard ratio [HR], 0.49; 95% CI, 0.39-0.62) and the minimal step count for benefit was 3,826 steps (HR, 0.75; 95% CI, 0.67-0.83).
 

Modifiable factors

The other major modifiable factors to consider are problems with special senses. Both vision loss and hearing loss have been associated with cognitive impairment.

Shang and colleagues published a meta-analysis of 14 cohort studies addressing vision impairment and cognitive function involving more than 6 million individuals.⁵ They concluded that vision impairment is associated with an increased risk of both dementia and cognitive impairment in older adults.

Loughrey and colleagues performed a meta-analysis of 36 studies addressing hearing loss and cognitive decline.⁶ They reported that, among cross-sectional studies, a significant association was found for cognitive impairment (odds ratio [OR], 2.00; 95% CI, 1.39-2.89) and dementia (OR, 2.42; 95% CI, 1.24-4.72). A similar finding was present in prospective cohort studies with a significant association being found for cognitive impairment (OR, 1.22; 95% CI, 1.09-1.36) and dementia (OR, 1.28; 95% CI, 1.02-1.59).

A 25-year prospective, population-based study of patients with hearing loss revealed a difference in the rate of change in MMSE score over the 25-year follow-up between participants with hearing loss not using hearing aids matched with controls who didn’t have hearing loss. Those with untreated hearing loss had more cognitive decline than that of patients without hearing loss.⁷ The subjects with hearing loss using a hearing aid had no difference in cognitive decline from controls.
 

Pearl

Several simple and safe interventions may protect our patients from cognitive decline. These include taking a daily multivitamin, walking more than 4,000 steps a day, and optimizing vision and hearing.

A 67-year-old man asks about what he can do to prevent dementia. He reports his mother had dementia, and he wants to do everything he can to prevent it. Which of the following has evidence of benefit?

A) Thiamine

B) Vitamin E

C) Multivitamin (MV)

D) Keto diet

E) Red wine
 

FDA-approved therapies for dementia

To date the actual therapies for dementia have been disappointing. Donepezil, the most prescribed medication for the treatment of dementia has a number-needed-to treat (NNT) over 17, and causes frequent side effects. Aducanumab was recently approved by the Food and Drug Administration for the treatment of Alzheimer’s disease (AD), but controversy has arisen, as the clinical results were modest, and the price tag will be large – estimated at $30,000-$50,000/year.

Preventive options that may decrease the likelihood of dementia

Patients often ask the question stated above. Regarding how to respond to that question, choice C, MV, has some recent evidence of benefit. Baker and colleagues studied the effect of cocoa extract and multivitamins on cognitive function in the COSMOS-Mind trial.¹ A total of 2,262 people were enrolled, and over 90% completed baseline and at least one annual cognitive assessment. Cocoa extract had no impact on global cognition (confidence interval [CI], –.02-.08, P = .28), but MV supplementation did have a statistically significant impact on global cognition (CI, .02-.12, P less than .007).

Vitamin E has been enthusiastically endorsed in the past as a treatment to prevent cognitive decline. The most recent Cochrane review on vitamin E concluded there was no evidence that the alpha-tocopherol form of vitamin E given to people with MCI prevents progression to dementia, or that it improves cognitive function in people with MCI or dementia due to AD.²

Exercise has long been a mainstay of our advice to patients as something they can do to help prevent dementia. Yu and colleagues did a meta-analysis of almost 400 randomized controlled trials and observational studies to grade the evidence on different interventions.³ They gave exercise a grade B for evidence of benefit.

A recent study addressed this issue, and I think it is helpful on quantifying how much exercise is needed. Del Pozo Cruz and colleagues did a prospective population-based cohort study of 78,000 adults aged 40-79, with an average of 6.9 years of follow up.⁴ The optimal step count was 9,826 steps (hazard ratio [HR], 0.49; 95% CI, 0.39-0.62) and the minimal step count for benefit was 3,826 steps (HR, 0.75; 95% CI, 0.67-0.83).
 

Modifiable factors

The other major modifiable factors to consider are problems with special senses. Both vision loss and hearing loss have been associated with cognitive impairment.

Shang and colleagues published a meta-analysis of 14 cohort studies addressing vision impairment and cognitive function involving more than 6 million individuals.⁵ They concluded that vision impairment is associated with an increased risk of both dementia and cognitive impairment in older adults.

Loughrey and colleagues performed a meta-analysis of 36 studies addressing hearing loss and cognitive decline.⁶ They reported that, among cross-sectional studies, a significant association was found for cognitive impairment (odds ratio [OR], 2.00; 95% CI, 1.39-2.89) and dementia (OR, 2.42; 95% CI, 1.24-4.72). A similar finding was present in prospective cohort studies with a significant association being found for cognitive impairment (OR, 1.22; 95% CI, 1.09-1.36) and dementia (OR, 1.28; 95% CI, 1.02-1.59).

A 25-year prospective, population-based study of patients with hearing loss revealed a difference in the rate of change in MMSE score over the 25-year follow-up between participants with hearing loss not using hearing aids matched with controls who didn’t have hearing loss. Those with untreated hearing loss had more cognitive decline than that of patients without hearing loss.⁷ The subjects with hearing loss using a hearing aid had no difference in cognitive decline from controls.
 

Pearl

Several simple and safe interventions may protect our patients from cognitive decline. These include taking a daily multivitamin, walking more than 4,000 steps a day, and optimizing vision and hearing.

Cocaine, methamphetamine, opioids, and cannabis may independently increase risk of atrial fibrillation (AFib), based on data from almost 24 million people.

While more work is needed to uncover causal links, physicians should be aware that these commonly abused substances could be driving new cases of AFib, reported investigators from the University of California, San Francisco.

“Though alcohol and tobacco smoking have each been associated with a heightened risk of [AFib], relationships between other drug use and [AFib] are poorly understood,” they wrote in European Heart Journal.

Some previous studies have ventured into this terrain, but most focused on fatal arrhythmias, or offered anecdotal evidence. This knowledge gap is particularly concerning for cannabis, the researchers noted, as medical and recreational use are on the rise.

American Heart Association

The present analysis included data from 23.5 million adults in California who received care through a hospital, emergency department, or outpatient surgery center during 2005-2015. Based on ICD-9 diagnostic codes, 132,834 of these patients used cannabis, 98,271 used methamphetamines, 48,701 used cocaine, and 10,032 used opiates. Inclusion required lack of AFib at baseline.

Reliance on ICD-9 codes makes the data “quite specific,” but lacking sensitivity, according to principal author Gregory M. Marcus, MD, cardiologist and professor of medicine at UCSF.

“If they were designated as using these drugs, that is very likely true,” Dr. Marcus said in an interview. “But certainly, the absence of any mention of use of these drugs does not exclude the possibility that some people were still using them. That would not create spurious false-positive relationships; if anything, it attenuates existing relationships.”

In other words, using ICD-9 codes reduced the power to detect an association between each drug and AFib, meaning any relationship needed to be sufficiently strong enough to generate a significant result.

At the end of the decade-long study period, 998,747 patients (4.2%) had developed incident AFib. After adjusting for potential confounders and mediators, all four drugs showed significant, independent associations with AFib. Methamphetamines presented the greatest risk (hazard ratio, 1.86%), followed by opiates (HR, 1.74), cocaine (HR, 1.61), and cannabis (HR, 1.35).

“Our findings provide the first evidence utilizing a longitudinal cohort to demonstrate that cannabis use predicts the future onset of AFib,” Dr. Marcus and colleagues wrote.

Dose-response relationships were not detected for any of the substances; however, usage levels were also derived from ICD-9 codes, which may have been insufficient for this purpose, according to the investigators.
 

Causal mechanisms deserve a closer look

Causal links between AFib and each of the drugs remain unclear. Citing prior research, Dr. Marcus and colleagues explained how methamphetamines are capable of “significant cardiac electrical remodeling,” while cocaine may cause sodium channel dysregulation, and opioids can render atrial myocytes more susceptible to oxidative damage. Although cannabis has previously been linked with hospitalization for arrhythmia, a pharmacologic driver of this phenomenon remains largely unexamined.

“We don’t know for sure precisely what the constituents are that are responsible for our findings,” Dr. Marcus said. “It’s possible that there are some effects that are much more generic, such as inhaling a burned substance. There is good evidence that if you inhale pretty much any sort of particulate matter, that increases inflammation in the body. Inflammation is known to be a trigger for atrial fibrillation.”

Alternatively, all four drugs – whether stimulants or depressants – cause “quite dramatic and often rapid effects on the autonomic nervous system,” Dr. Marcus said, noting that these rapid swings are a known trigger for AFib.

Brian Olshansky, MD, emeritus professor of internal medicine-cardiovascular medicine at the University of Iowa, Iowa City, suggested that nonpharmacologic factors are likely also playing a role.

“All these drugs have slightly different mechanisms of action, so there’s not one mechanism that would explain why all of them would cause atrial fibrillation,” Dr. Olshansky said in an interview. “That does suggest that there’s something else going on, besides just the drug itself. It would be potentially concerning if we were to lay the blame totally on these drugs.”

Dr. Olshansky, who recently coauthored a review of stimulant drugs and arrhythmias, suggested that lifestyle, comorbidities, and drug impurities may have added to the risk of AF.

“[The investigators] did try to correct for that kind of stuff, but it’s very hard to correct for a lot of the issues that may be ongoing with individuals who partake in these drugs,” Dr. Olshansky said in an interview. “They may not be a healthy lot, in general.”

Still, considering previous data linking drugs of abuse with arrhythmias, he said the detected risks were “intriguing,” and deserved a closer look.

“It’s a nice groundbreaking study, with regard to the fact that they showed unique relationships that we don’t completely understand,” Dr. Olshansky said. “It opens up a new opportunity for further investigation.”

The investigators disclosed relationships with InCarda, Baylis Medical, Johnson & Johnson, and others. Dr. Olshansky disclosed no relevant competing interests.

Recently there have been articles and discussions about how involved physicians should be in patient gun ownership.

There are valid points all around. Some of my colleagues, especially those in general practice, feel that they don’t have enough time to add more screening questions on top of those they already have. Others point out that routinely asking about gun ownership is none of our business. A third view I’ve seen is that very few doctors are in a position to teach issues of gun safety.

In my field, with certain patients, I do ask. Namely, the demented.

Anyone with concerning cognitive deficits shouldn’t have access to guns. As their judgment fades and their impulsivity worsens, they often don’t realize right from wrong. They might open fire on family members thinking they’re burglars. Some of them see suspicious people out in the yard that are more likely hallucinations or simply passersby.

In more advanced cases of dementia, patients may not even realize what they’re holding, but that doesn’t make it any less dangerous. Probably more so, since they’re not going to be careful with it.

Another scary issue I sometimes encounter is when patients with dementia find a gun at home – usually one that belonged to a deceased spouse and that family isn’t aware of. No one really knows if it’s working, or loaded, though we have to assume it is. They find it and start carrying it out on walks, pointing it at the mailman who they think is trespassing, etc. Sometimes the police get called. These situations are extremely dangerous for all involved.

It’s pretty easy for someone to get shot under these circumstances. It’s like leaving a gun out and having a toddler find it. They don’t mean any harm, but they’re still just as deadly as someone who does.

These people also have access to knives, which can be equally deadly, but knives aren’t guns. They don’t have the range or hitting power that make firearms so dangerous. It’s a lot easier to disarm an elderly patient with a steak knife if need be.

So, like my colleagues in psychiatry, I ask about guns in certain situations that involve dementia. Are there any guns? If so, are they locked up safely where the person can’t access them?

I’m not making a statement for or against gun ownership here. But I think all of us would agree that someone with impaired judgment, cognition, self-control, reasoning, and memory shouldn’t have access to guns.

In neurology, that’s a decent chunk of my patients. So for everyone’s safety, I ask them (and, more importantly, their families) about guns.
