People with migraine tend to have lower levels of physical activity than those without migraine despite the beneficial effects of physical activity on reducing frequency of migraine, according to a presentation at the American Headache Society’s 2021 annual meeting.

Though reliable research is sparse overall on how much physical activity people with migraine get, enough exists to reveal the need for clinicians to help patients identify ways to increase their levels of physical activity and make it a habit, said Dale S. Bond, PhD, a professor of psychiatry and human behavior at the Miriam Hospital and Brown University, both in Providence, R.I.

He emphasized the need not only to replace sedentary time with physical activity but also to reduce sedentary time overall.

“It’s important to note that because active and sedentary represent different behavioral domains, people can still be active – that is, achieving recommended levels of moderate to vigorous physical activity [MVPA] – but still be highly sedentary because they sit for long hours throughout the day,” Dr. Bond said. “This is important because MVPA will not necessarily eliminate the health risks of long hours of sitting.”

Dr. Bond reviewed the existing literature on physical activity and sedentary behavior among patients with migraine. His presentation, “Move More, Sit Less,” aimed at finding ways to incorporate more physical activity into the daily lives of those with migraine. Dr. Bond began by briefly reviewing the well-established benefits of physical activity, including healthy sleep; cardiovascular, respiratory, musculoskeletal, mental, and cognitive health; and metabolic functioning.

“Physical activity and exercise in particular enhances the functioning of bodily systems, including those that have direct relevance to migraine in its comorbidities,” Dr. Bond said. “The positive systemic effects of exercise on bodily systems carries potential to reduce migraine severity and related disability and morbidity.”

He also explained the ways in which excessive sedentary time can exacerbate migraine triggers. “Long periods of interrupted sitting elevated levels of glucose and fat in the bloodstream, which in turn triggers the immune system to attack the body via inflammation,” Dr. Bond said. “Low grade chronic inflammation has long been hypothesized to play a role in migraine pathogenesis.”
 

Recommended levels of exercise

The World Health Organization and the U.S. Department of Health & Human Services recommends at least 150-300 minutes of moderate-intensity aerobic physical activity or 75-150 minutes of vigorous activity each week. An additional recommendation is at least 2 days per week of muscle strengthening activities that involve all major muscle groups.

While neither of those organizations has specific guidelines on how much reduction of sedentary time is recommended, the Canadian Society for Exercise Physiology recommends limiting sedentary time to 8 or fewer hours per day.
 

Exercise and migraine

“Unfortunately, at present, we have very few studies from which to draw conclusions about the extent to which individuals with migraine adhere to physical activity and sedentary guidelines,” Dr. Bond said. Existing studies vary widely in sample types, study design, physical activity measure and MVPA outcome, including the type or definition of MVPA. “This wide variability in measures and outcomes makes it challenging to draw any conclusions about adherence to guidelines among individuals with migraine,” he said.

Existing evidence suggests anywhere from 32% to 66% of migraine patients are at least moderately active, though it’s not clear what constitutes “moderately active” behavior. It appears that activity levels of patients with migraine are low overall, but it’s less clear the extent to which these levels are lower than in controls given the paucity of evidence.

In one of the few studies using objective measures to assess physical activity in migraine patients, the daily level of MVPA was significantly lower in 25 women with migraine than in 25 age- and body mass index–matched women without migraine (P <. 003). Both groups had obesity. The same study found that virtually no women with migraine adhered to the guidelines recommending less than 8 hours a day of sedentary time, compared with 30% of women without migraine.

“Also, low physical activity and high sedentary levels appear to be consistent across headache and nonheadache days,” Dr. Bond said. “This finding in particular raises an interesting question: If migraine severity is not related to physical activity and sedentary time, what is it about migraine that contributes to an inactive and sedentary lifestyle?”

Dr. Bond noted that future research needs to include reports of frequency, duration, and intensity of activities performed as well as the percentage of participants who meet guidelines for physical activity and sedentary time. Ideally, these studies should include not only self-report but also objective measures of activity as well as assess sleep and identify barriers and facilitators to physical activity in patients.
 

Exercise avoidance

Dr. Bond described findings from survey of 100 women he conducted to better understand potential barriers and reported that 78% of patients report intentionally avoiding physical activity. These patients typically avoided it an average of 4 days per week, regardless of intensity, and additional survey findings found “that participants who reported any avoidance had stronger beliefs that physical activity would both trigger and worsen a migraine attack, compared with participants who reported no avoidance,” he said.

That finding matches the clinical experience of Jennifer Robblee, MD, MSc, assistant professor of neurology at Barrow Neurological Institute in Phoenix, who viewed the presentation but was not involved with it.

“They often feel that it is a trigger for worsening an attack or, for some people, can actually trigger an attack, and that they feel worse in the midst of an attack when they’re exercising,” Dr. Robblee said in an interview regarding her patients who exercise less frequently. “Since so many of the patients I see have a daily and constant headache, it’s about how they can get themselves to start to exercise when something makes them feel worse, even if it makes them feel better in the long run.”

Yet, experimental research suggests that physical activity is not necessarily a reliable trigger of migraine attacks and only worsens migraine in a minority of attacks, Dr. Bond said, revealing an interesting paradox: “While engaging in regular physical activity is an important migraine management strategy, most individuals in the study reported doing the exact opposite – that is, avoiding physical activity as a management strategy – and this strategy was associated with higher frequency and duration of attacks. Research from our group and others also suggested individuals with migraine could be overestimating the role that physical activity hasn’t triggering or worsening of attacks.”
 

Encouraging patients to exercise

Since the benefits of physical activity and limiting sedentary time outweigh the potential harms, “some physical activity is better than none,” Dr. Bond said. To help patients begin increasing their physical activity, he recommended advising them to start with small amounts and then gradually increase frequency, intensity, and duration over time.

Dr. Robblee follows a similar approach, taking into account each patient’s particular circumstances and any medications they’re taking, including the side effects of those medications.

“It’s about starting where they are,” Dr. Robblee said. “Some patients, despite having severe migraine, have built themselves up so they’re doing exercise three or four times per week, or every day, and I have other people who never exercise,” she said. “For those patients who are very sedentary, if I can get them to start with 5 minutes per week so they have that sense of accomplishment, then that’s where I start. Then slowly build it up over time. Like most things in the migraine world, I individualize it for the person.”

Dr. Bond offered the following specific tips to clinicians in educating and encouraging patients to increase physical activity:

• Educate patients regarding the short-and long-term benefits of moving more and sitting less, both for their migraines and for overall health.
• Correct misconceptions about the negative effects of physical activity as it relates to migraines.
• Personalize the rationale for physical activity to that patient’s specific values and personal goals.
• Encourage patients to use an activity tracker, both for tracking physical activity and sedentary time, and to monitor migraine attacks, stress, energy levels, and fatigue on days they do and do not exercise.
• Help patients set goals for eventually meeting MVPA recommendations and interrupting prolonged periods of sitting with brief movement breaks.
• Help patients identify rewards for meeting goals that are tied to the activity, such as new exercise clothing.
• Encourage patients to identify a consistent time for physical activity each day to establish a habit, “ideally in the morning before barriers and life get in the way,” he said.

Eventually, physical activity itself should become intrinsically rewarding, Dr. Bond said.

“To limit sitting and encourage more movement throughout the day, we want to make the choice to engage in physical activity easier by adding environmental cues that encourage physical activity,” he said. “Conversely, we want to make the choice to engage in sedentary behavior more difficult by increasing the amount of effort that is required to engage in these behaviors.”

Dr. Robblee found Dr. Bond’s emphasis on sitting less – distinct from moving more – a helpful frame to consider with her patients. “I really like the approach of looking at it from that approach: in addition to how do we get you up and moving, how much time are you sitting, and how often can you break that up into smaller increments so that you’re up more often?” Dr. Robblee said. “That sometimes sounds less scary than ‘let’s get you exercising.’ So ‘let’s get you sitting a little bit less.’ I think that is something I might start to adopt.”

Ubrogepant showed effectiveness for acute treatment of migraine when used with an anti–calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) preventive or with onabotulinumtoxinA (onabotA), or both, according to preliminary findings presented at the American Headache Society’s 2021 annual meeting.

“Because prevention [with mAbs] is rarely 100% effective, virtually everyone on preventive treatment needs to also take acute treatment,” presenter Richard B. Lipton, MD, a professor of neurology and director of the Montefiore Headache Center at Albert Einstein College of Medicine, New York, said in an interview after his presentation. He explained that ubrogepant, a small-molecule CGRP receptor blocker, is approved for acute treatment of migraine, while mAbs, which block the CGRP receptor or CGRP itself, are approved for prevention. “Many people predicted that gepants would not work in people on CGRP-targeted mAbs because of overlapping mechanisms.”

Dr. Lipton himself was not surprised by the findings, however. “For me, the surprise was that ubrogepant worked so well,” he said.  
 

Novel data collection

Uniquely, his study used an entirely remote design with mobile applications to safely evaluate the drug’s real-world effectiveness in the midst of the COVID-19 pandemic. The prospective, observational study used the mobile app Migraine Buddy to collect data and assess outcomes from the use of 50 mg or 100 mg of ubrogepant along with a mAb, onabotA, or both.

In most migraine trials, researchers ask patients to track their symptoms in electronic diaries they learn how to use in the clinic.

“One disadvantage of this approach is that people usually need to carry two devices, the study device and their smartphone,” Dr. Lipton said in an interview. “In this study, people download an app at home to their smartphone and only need to carry one device. Though remote studies are particularly valuable in the time of pandemic, I believe that apps like Migraine Buddy are and will remain a valuable tool for addressing many research questions.”

Jennifer Robblee, MD, MSc, an assistant professor of neurology at Barrow Neurological Institute in Phoenix, viewed the presentation and was also impressed with the novel use of a smartphone app to conduct the study. “I think that was a unique and cool demonstration of what can be done with the apps out there now,” Dr. Robblee said in an interview. “If you want to have really good tracking and more through tracking, apps like this are fabulous and are very patient forward and patient friendly.”
 

Combination therapy

The researchers invited 4,541 adults to participate in the study if they had previously reported at least three migraine attacks in the past 30 days and if they had treated at least three prior attacks with ubrogepant. The 483 participants who enrolled after consent and screening included 272 taking ubrogepant with mAb, 132 participants taking ubrogepant with onabotA, and 79 taking ubrogepant with both onabotA and mAb.

For 30 days, participants reported in the app’s diary their pain relief and the time elapsed since taking ubrogepant until they returned to normal functioning. Endpoints included meaningful pain relief – defined as “a level of pain relief that is meaningful to you” – and return to normal function at 2 and 4 hours.

During the study, 352 participants reported treating a migraine attack with a single dose of ubrogepant, and 78 participants treated migraine with two doses. The former group included 193 patients in the ubrogepant plus mAb group, 102 patients in the ubrogepant plus onabotA group, and 57 patients in the ubrogepant plus both group. Because of the limited enrollment in the second two arms, the data Dr. Lipton presented data only on the ubrogepant with mAb arm.

Most of this group (89.1%) was female, with an average age of 40 years and an average Migraine Disability Assessment score of 72.2. Most of the patients were taking erenumab (44.6%) or galcanezumab (34.2%) with the remaining patients taking fremanezumab (17.6%), eptinezumab (3.1%) or multiple mAbs (0.5%). Most participants (59.6%) were prescribed 100-mg ubrogepant dose while the remaining participants took 50 mg.

The analysis of the ubrogepant plus mAb group revealed that 64.2% of patients reported meaningful pain relief at 2 hours, and 84.5% had meaningful pain relief 4 hours after taking ubrogepant. The odds of achieving meaningful pain relief were statistically significant at both time points and remained significant after adjustment for participants’ age, Migraine Disability Assessment score and self-reported prescribed ubrogepant dose (P < .001).

“This study shows that in patients with migraine on CGRP-targeted monoclonal antibodies, ubrogepant is an acute treatment to consider for breakthrough headaches,” Dr. Lipton said. He added that they have now completed the study with more participants and begun analyzing all three groups.

“Full analyses will include data from multiple attacks, attacks treated with a second dose of ubrogepant, additional daily and 30-day effectiveness measures for use of ubrogepant with onabotA and use of ubrogepant with both onabotA and CGRP mAbs,” Dr. Lipton said.

While the findings did not surprise Dr. Robblee, she was happy to see a study that explicitly testing the combination of these treatments, especially given access challenges. “Right now, because treatments are new, we get a lot of insurance denials,” Dr. Robblee said in an interview. “It’s great to have a study out there that we can turn to and say, ‘hey, look, they had all these patients safely using these together.’ It’s going to help us improve access for patients.”

Though Dr. Robblee typically uses old-school pen-and-calendar diaries with her patients, she also sees potential for the use of apps going forward, just as she sees for virtual health care.

“I’ve found telemedicine in general to be a really great addition to the migraine world, and this plays into our ability to use telemedicine paired with tracking,” Dr. Robblee said. “In so many studies, we’re doing a diary anyway, so if there are standard diaries and programs we’re all using, that would be a nice way to do these.”

She notes that most symptom tracking for pain is subjective already, and these apps often include the options to print out the data or to export or transfer it electronically to physicians. “It’s giving us meaningful data,” she said.

The research was funded by AbbVie. Dr. Lipton has received honoraria or research support from AbbVie, Amgen, Biohaven, Dr. Reddy’s Laboratories, electroCore, Eli Lilly, eNeura Therapeutics, GlaxoSmithKline, Merck, Novartis, Teva, Vector and Vedanta Research. He holds stock options in Biohaven and Ctrl M. Dr. Robblee is a principal investigator for a study sponsored by Eli Lilly and receives stipends for MedLink Neurology and Neurodiem.

The prospective, observational study used the mobile app Migraine Buddy to collect data and assess outcomes from the use of 50 mg or 100 mg of ubrogepant along with a mAb, onabotA, or both.

In most migraine trials, researchers ask patients to track their symptoms in electronic diaries they learn how to use in the clinic.

“One disadvantage of this approach is that people usually need to carry two devices, the study device and their smartphone,” Dr. Lipton said in an interview. “In this study, people download an app at home to their smartphone and only need to carry one device. Though remote studies are particularly valuable in the time of pandemic, I believe that apps like Migraine Buddy are and will remain a valuable tool for addressing many research questions.”

Jennifer Robblee, MD, MSc, an assistant professor of neurology at Barrow Neurological Institute in Phoenix, viewed the presentation and was also impressed with the novel use of a smartphone app to conduct the study. “I think that was a unique and cool demonstration of what can be done with the apps out there now,” Dr. Robblee said in an interview. “If you want to have really good tracking and more through tracking, apps like this are fabulous and are very patient forward and patient friendly.”
 

Combination therapy

The researchers invited 4,541 adults to participate in the study if they had previously reported at least three migraine attacks in the past 30 days and if they had treated at least three prior attacks with ubrogepant. The 483 participants who enrolled after consent and screening included 272 taking ubrogepant with mAb, 132 participants taking ubrogepant with onabotA, and 79 taking ubrogepant with both onabotA and mAb.

For 30 days, participants reported in the app’s diary their pain relief and the time elapsed since taking ubrogepant until they returned to normal functioning. Endpoints included meaningful pain relief – defined as “a level of pain relief that is meaningful to you” – and return to normal function at 2 and 4 hours.

During the study, 352 participants reported treating a migraine attack with a single dose of ubrogepant, and 78 participants treated migraine with two doses. The former group included 193 patients in the ubrogepant plus mAb group, 102 patients in the ubrogepant plus onabotA group, and 57 patients in the ubrogepant plus both group. Because of the limited enrollment in the second two arms, the data Dr. Lipton presented data only on the ubrogepant with mAb arm.

Most of this group (89.1%) was female, with an average age of 40 years and an average Migraine Disability Assessment score of 72.2. Most of the patients were taking erenumab (44.6%) or galcanezumab (34.2%) with the remaining patients taking fremanezumab (17.6%), eptinezumab (3.1%) or multiple mAbs (0.5%). Most participants (59.6%) were prescribed 100-mg ubrogepant dose while the remaining participants took 50 mg.

The analysis of the ubrogepant plus mAb group revealed that 64.2% of patients reported meaningful pain relief at 2 hours, and 84.5% had meaningful pain relief 4 hours after taking ubrogepant. The odds of achieving meaningful pain relief were statistically significant at both time points and remained significant after adjustment for participants’ age, Migraine Disability Assessment score and self-reported prescribed ubrogepant dose (P < .001).

“This study shows that in patients with migraine on CGRP-targeted monoclonal antibodies, ubrogepant is an acute treatment to consider for breakthrough headaches,” Dr. Lipton said. He added that they have now completed the study with more participants and begun analyzing all three groups.

“Full analyses will include data from multiple attacks, attacks treated with a second dose of ubrogepant, additional daily and 30-day effectiveness measures for use of ubrogepant with onabotA and use of ubrogepant with both onabotA and CGRP mAbs,” Dr. Lipton said.

While the findings did not surprise Dr. Robblee, she was happy to see a study that explicitly testing the combination of these treatments, especially given access challenges. “Right now, because treatments are new, we get a lot of insurance denials,” Dr. Robblee said in an interview. “It’s great to have a study out there that we can turn to and say, ‘hey, look, they had all these patients safely using these together.’ It’s going to help us improve access for patients.”

Though Dr. Robblee typically uses old-school pen-and-calendar diaries with her patients, she also sees potential for the use of apps going forward, just as she sees for virtual health care.

“I’ve found telemedicine in general to be a really great addition to the migraine world, and this plays into our ability to use telemedicine paired with tracking,” Dr. Robblee said. “In so many studies, we’re doing a diary anyway, so if there are standard diaries and programs we’re all using, that would be a nice way to do these.”

She notes that most symptom tracking for pain is subjective already, and these apps often include the options to print out the data or to export or transfer it electronically to physicians. “It’s giving us meaningful data,” she said.

The research was funded by AbbVie. Dr. Lipton has received honoraria or research support from AbbVie, Amgen, Biohaven, Dr. Reddy’s Laboratories, electroCore, Eli Lilly, eNeura Therapeutics, GlaxoSmithKline, Merck, Novartis, Teva, Vector and Vedanta Research. He holds stock options in Biohaven and Ctrl M. Dr. Robblee is a principal investigator for a study sponsored by Eli Lilly and receives stipends for MedLink Neurology and Neurodiem.

Ubrogepant showed effectiveness for acute treatment of migraine when used with an anti–calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) preventive or with onabotulinumtoxinA (onabotA), or both, according to preliminary findings presented at the American Headache Society’s 2021 annual meeting.

“Because prevention [with mAbs] is rarely 100% effective, virtually everyone on preventive treatment needs to also take acute treatment,” presenter Richard B. Lipton, MD, a professor of neurology and director of the Montefiore Headache Center at Albert Einstein College of Medicine, New York, said in an interview after his presentation. He explained that ubrogepant, a small-molecule CGRP receptor blocker, is approved for acute treatment of migraine, while mAbs, which block the CGRP receptor or CGRP itself, are approved for prevention. “Many people predicted that gepants would not work in people on CGRP-targeted mAbs because of overlapping mechanisms.”

Dr. Lipton himself was not surprised by the findings, however. “For me, the surprise was that ubrogepant worked so well,” he said.

Three or more weeks of oral anticoagulation (OAC) sometimes isn’t up to the job of clearing any potentially embolic left atrial (LA) thrombi before procedures like cardioversion or catheter ablation in patients with atrial fibrillation (AF). Such OAC-defiant LA thrombi aren’t common, nor are they rare enough to ignore, suggests a new meta-analysis that might also have identified features that predispose to them.

Such predictors of LA clots that persist despite OAC could potentially guide selective use of transesophageal echocardiography (TEE) instead of more routine policies to either use or not use TEE for thrombus rule-out before rhythm-control procedures, researchers propose.

Their prevalence was about 2.7% among the study’s more than 14,000 patients who received at least 3 weeks of OAC with either vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) before undergoing TEE.

But OAC-resistant LA thrombi were two- to four-times as common in patients with than without certain features, including AF other than paroxysmal and higher CHADS2 and CHA2DS2-VASc stroke risk-stratification scores.

“TEE imaging in select patients at an elevated risk of LA thrombus, despite anticoagulation status, may be a reasonable approach to minimize the risk of thromboembolic complications following cardioversion or catheter ablation,” propose the study’s authors, led by Antony Lurie, BMSC, Population Health Research Institute, Hamilton, Ont. Their report was published in the June 15 issue of the Journal of the American College of Cardiology.

Guidelines don’t encourage TEE before cardioversion in patients who have been on OAC for at least 3 weeks, the group notes, and policies on TEE use before AF ablation vary widely regardless of anticoagulation status.

The current study suggests that 3 weeks of OAC isn’t enough for a substantial number of patients, who might be put at thromboembolic risk if TEE were to be skipped before rhythm-control procedures.

Conversely, many patients unlikely to have LA thrombi get preprocedure TEE anyway. That can happen “irrespective of how long they’ve been anticoagulated, their pattern of atrial fibrillation, or their stroke risk,” senior author Jorge A. Wong, MD, MPH, Population Health Research Institute and McMaster University, Hamilton, Ont., told this news organization.

But “TEE is an invasive imaging modality, so it is associated with small element of risk.” The current study, Dr. Wong said, points to potential risk-stratification tools clinicians might use to guide more selective TEE screening.

“At sites where TEEs are done all the time for patients undergoing ablation, one could use several of these risk markers to perhaps tailor use of TEE in individuals,” Dr. Wong said. “For example, in people with paroxysmal atrial fibrillation, we found that the risk of left atrial appendage clot was approximately 1% or less.” Screening by TEE might reasonably be avoided in such patients.

“Fortunately, continued oral anticoagulation already yields low peri-procedural stroke rates,” observes an accompanying editorial from Paulus Kirchhof, MD, and Christoph Sinning, MD, from the University Heart & Vascular Center and German Centre of Cardiovascular Research, Hamburg.

“Based on this new analysis of existing data, a risk-based use of TEE imaging in anticoagulated patients could enable further improvement in the safe delivery of rhythm control interventions in patients with AF,” the editorialists agree.

The meta-analysis covered 10 prospective and 25 retrospective studies with a total of 14,653 patients that reported whether LA thrombus was present in patients with AF or atrial flutter (AFL) who underwent TEE after at least 3 weeks of VKA or DOAC therapy. Reports for 30 of the studies identified patients by rhythm-control procedure, and the remaining five didn’t specify TEE indications.

The weighted mean prevalence of LA thrombus at TEE was 2.73% (95% confidence interval, 1.95%-3.80%). The finding was not significantly changed in separate sensitivity analyses, the report says, including one limited to studies with low risk of bias and others excluding patients with valvular AF, interrupted OAC, heparin bridging, or subtherapeutic anticoagulation, respectively.

Patients treated with VKA and DOACs showed similar prevalences of LA thrombi, with means of 2.80% and 3.12%, respectively (P = .674). The prevalence was significantly higher in patients:

• with nonparoxysmal than with paroxysmal AF/AFL (4.81% vs. 1.03%; P < .001)
• undergoing cardioversion than ablation (5.55% vs. 1.65; P < .001)
• with CHA2DS2-VASc scores of at least 3 than with scores of 2 or less (6.31% vs. 1.06%; P < .001).

A limitation of the study, observe Dr. Kirchhof and Dr. Sinning, “is that all patients had a clinical indication for a TEE, which might be a selection bias. When a thrombus was found on TEE, clinical judgment led to postponing of the procedure,” thereby avoiding potential thromboembolism.

“Thus, the paper cannot demonstrate that presence of a thrombus on TEE is related to peri-procedural ischemic stroke,” they write.

The literature puts the risk for stroke or systemic embolism at well under 1% for patients anticoagulated with either VKA or DOACs for at least 3 weeks prior to cardioversion, in contrast to the nearly 3% prevalence of LA appendage thrombus by TEE in the current analysis, Dr. Wong observed.

“So we’re seeing a lot more left atrial appendage thrombus than we would see stroke,” but there wasn’t a way to determine whether that increases the stroke risk, he agreed.Dr. Wong, Dr. Lurie, and the other authors report no relevant conflicts. Dr. Kirchhof discloses receiving partial support “from several drug and device companies active in atrial fibrillation” and to being listed as inventor on two AF-related patents held by the University of Birmingham. Dr. Sinning reports no relevant relationships.

Graduates of international medical schools died from COVID-19 in disproportionate numbers in the United States in 2020, researchers report.

“I’ve always felt that international medical graduates [IMGs] in America are largely invisible,” said senior author Abraham Verghese, MD, MFA, an infectious disease specialist at Stanford (Calif.) University. “Everyone is aware that there are foreign doctors, but very few are aware of how many there are and also how vital they are to providing health care in America.”

IMGs made up 25% of all U.S. physicians in 2020 but accounted for 45% of those whose deaths had been attributed to COVID-19 through Nov. 23, 2020, Deendayal Dinakarpandian, MD, PhD, clinical associate professor of medicine at Stanford (Calif.) University, and colleagues report in JAMA Network Open.

IMGs are more likely to work in places where the incidence of COVID-19 is high and in facilities with fewer resources, Dr. Verghese said in an interview. “So, it’s not surprising that they were on the front lines when this thing came along,” he said.

To see whether their vulnerability affected their risk for death, Dr. Dinakarpandian and colleagues collected data from Nov. 23, 2020, from three sources of information regarding deaths among physicians: MedPage Today, which used investigative and voluntary reporting; Medscape, which used voluntary reporting of verifiable information; and a collaboration of The Guardian and Kaiser Health News, which used investigative reporting.

The Medscape project was launched on April 1, 2020. The MedPage Today and The Guardian/Kaiser Health News projects were launched on April 8, 2020.

Dr. Verghese and colleagues researched obituaries and news articles referenced by the three projects to verify their data. They used DocInfo to ascertain the deceased physicians’ medical schools.

After eliminating duplications from the lists, the researchers counted 132 physician deaths in 28 states. Of these, 59 physicians had graduated from medical schools outside the United States, a death toll 1.8 times higher than the proportion of IMGs among U.S. physicians (95% confidence interval, 1.52-2.21; P < .001).

New York, New Jersey, and Florida accounted for 66% of the deaths among IMGs but for only 45% of the deaths among U.S. medical school graduates.

Within each state, the proportion of IMGs among deceased physicians was not statistically different from their proportion among physicians in those states, with the exception of New York.

Two-thirds of the physicians’ deaths occurred in states where IMGs make up a larger proportion of physicians than in the nation as a whole. In these states, the incidence of COVID-19 was high at the start of the pandemic.

In New York, IMGs accounted for 60% of physician deaths, which was 1.62 times higher (95% CI, 1.26-2.09; P = .005) than the 37% among New York physicians overall.

Physicians who were trained abroad frequently can’t get into the most prestigious residency programs or into the highest paid specialties and are more likely to serve in primary care, Dr. Verghese said. Overall, 60% of the physicians who died of COVID-19 worked in primary care.

IMGs often staff hospitals serving low-income communities and communities of color, which were hardest hit by the pandemic and where personal protective equipment was hard to obtain, said Dr. Verghese.

In addition to these risks, IMGs sometimes endure racism, said Dr. Verghese, who obtained his medical degree at Madras Medical College, Chennai, India. “We’ve actually seen in the COVID era, in keeping with the sort of political tone that was set in Washington, that there’s been a lot more abuses of both foreign physicians and foreign looking physicians – even if they’re not foreign trained – and nurses by patients who have been given license. And I want to acknowledge the heroism of all these physicians.”

The study was partially funded by the Presence Center at Stanford. Dr. Verghese is a regular contributor to Medscape.

Graduates of international medical schools died from COVID-19 in disproportionate numbers in the United States in 2020, researchers report.

“I’ve always felt that international medical graduates [IMGs] in America are largely invisible,” said senior author Abraham Verghese, MD, MFA, an infectious disease specialist at Stanford (Calif.) University. “Everyone is aware that there are foreign doctors, but very few are aware of how many there are and also how vital they are to providing health care in America.”

IMGs made up 25% of all U.S. physicians in 2020 but accounted for 45% of those whose deaths had been attributed to COVID-19 through Nov. 23, 2020, Deendayal Dinakarpandian, MD, PhD, clinical associate professor of medicine at Stanford (Calif.) University, and colleagues report in JAMA Network Open.

IMGs are more likely to work in places where the incidence of COVID-19 is high and in facilities with fewer resources, Dr. Verghese said in an interview. “So, it’s not surprising that they were on the front lines when this thing came along,” he said.

To see whether their vulnerability affected their risk for death, Dr. Dinakarpandian and colleagues collected data from Nov. 23, 2020, from three sources of information regarding deaths among physicians: MedPage Today, which used investigative and voluntary reporting; Medscape, which used voluntary reporting of verifiable information; and a collaboration of The Guardian and Kaiser Health News, which used investigative reporting.

The Medscape project was launched on April 1, 2020. The MedPage Today and The Guardian/Kaiser Health News projects were launched on April 8, 2020.

Dr. Verghese and colleagues researched obituaries and news articles referenced by the three projects to verify their data. They used DocInfo to ascertain the deceased physicians’ medical schools.

After eliminating duplications from the lists, the researchers counted 132 physician deaths in 28 states. Of these, 59 physicians had graduated from medical schools outside the United States, a death toll 1.8 times higher than the proportion of IMGs among U.S. physicians (95% confidence interval, 1.52-2.21; P < .001).

New York, New Jersey, and Florida accounted for 66% of the deaths among IMGs but for only 45% of the deaths among U.S. medical school graduates.

Within each state, the proportion of IMGs among deceased physicians was not statistically different from their proportion among physicians in those states, with the exception of New York.

Two-thirds of the physicians’ deaths occurred in states where IMGs make up a larger proportion of physicians than in the nation as a whole. In these states, the incidence of COVID-19 was high at the start of the pandemic.

In New York, IMGs accounted for 60% of physician deaths, which was 1.62 times higher (95% CI, 1.26-2.09; P = .005) than the 37% among New York physicians overall.

The optimal first step to address mild to moderately elevated blood pressure and cholesterol in otherwise healthy adults is a “prescription” to sit less and move more, the American Heart Association says in a new scientific statement.

“The current American Heart Association guidelines for diagnosing high blood pressure and cholesterol recognize that otherwise healthy individuals with mildly or moderately elevated levels of these cardiovascular risk factors should actively attempt to reduce these risks,” Bethany Barone Gibbs, PhD, chair of the statement writing group, said in an AHA news release.

“The first treatment strategy for many of these patients should be healthy lifestyle changes beginning with increasing physical activity,” said Dr. Gibbs, from the University of Pittsburgh.

The 12-page AHA scientific statement – Physical Activity as a Critical Component of First-Line Treatment for Elevated Blood Pressure or Cholesterol: Who, What, and How? – was published online June 2 in Hypertension.
 

Every little bit helps

According to the AHA, about 21% of American adults have systolic blood pressure between 120 and 139 mm Hg, or diastolic blood pressure between 80 and 89 mm Hg, which meets the criteria for lifestyle-only treatment for elevated BP outlined in the American College of Cardiology (ACC)/AHA high blood pressure guideline.

In addition, about 28% of American adults have LDL cholesterol above 70 mg/dL and otherwise meet the low-risk criteria for heart disease or stroke. These individuals would meet the criteria for lifestyle-only treatment outlined in the 2018 ACC/AHA cholesterol treatment guidelines, which include increased physical activity, weight loss, better diet, smoking cessation, and moderating alcohol intake.

“Of the recommended lifestyle changes, increasing physical activity has extensive benefits, including improving both blood pressure and blood cholesterol, that are comparable, superior, or complementary to other healthy lifestyle changes,” the writing group says.

“Physical activity assessment and prescription are an excellent lifestyle behavior treatment option for all patients, including for the large population of mild-moderate-risk patients with elevated blood pressure and blood cholesterol,” they note.

Research has shown that increasing physical activity can lead to clinically meaningful 3 or 4 mm Hg reductions in systolic and diastolic blood pressure, and 3 to 6 mg/dL decreases in LDL cholesterol, the authors point out.

Previous evidence also shows that physically active people have a 21% lower risk of developing cardiovascular disease and a 36% lower risk for death from cardiovascular diseases than those who are not physically active.

Physical activity also has benefits beyond heart health, including a lower risk for some cancers; improved bone, brain, and mental health; and better sleep, they note.

The U.S. Department of Health and Human Services 2018 physical activity guidelines advise Americans to log 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous aerobic activity each week and to participate in two or more weekly strength training sessions.

However, there is no minimum amount of time to receive benefits from physical activity.

“Every little bit of activity is better than none. Even small initial increases of 5 to 10 minutes a day can yield health benefits,” Dr. Gibbs said.
 

Translational advice for clinicians

The AHA statement encourages clinicians to ask patients about their physical activity at every interaction; provide ideas and resources to help patients improve and sustain regular life-long physical activity; and encourage and celebrate small increases in activity, such as walking more or taking the stairs, to help with motivation.

“In our world where physical activity is increasingly engineered out of our lives and the overwhelming default is to sit – and even more so now as the nation and the world is practicing quarantine and isolation to reduce the spread of coronavirus – the message that we must be relentless in our pursuit to ‘sit less and move more’ throughout the day is more important than ever,” said Dr. Gibbs.

The statement was prepared by a volunteer writing group on behalf of the AHA Council on Lifestyle and Cardiometabolic Health; the Council on Cardiovascular and Stroke Nursing; and the Council on Clinical Cardiology.

This research had no commercial funding. A list of disclosures for the writing group is available with the original article.

Further evidence that powerful magnets in some Apple iPhones can interfere with cardiac implantable electronic devices (CIEDs) comes from a small study that also suggests some devices are more susceptible than others.

The iPhone 12 Pro Max with MagSafe technology interfered with CIEDs implanted in three consecutive patients presenting to an electrophysiology lab and in 8 of 11 implantable cardioverter defibrillators (ICDs) and pacemakers (72.7%) still in their original packaging.

The results, published in the Journal of the American Heart Association, are consistent with a widely publicized single-patient report this February and evidence of electromagnetic interference with fitness wristbands and e-cigarettes.

The MagSafe technology supports wireless charging and is optimized by a ring-shaped array of magnets. Although magnet mode activation has been shown to occur in CIEDs with exposure to a magnetic field as low as 10 gauss, the field strength of the iPhone 12 Pro Max can be greater than 50 G when in direct contact, the researchers determined.

“If this becomes a standard in a lot of the new smartphones or companies start to use stronger magnets ... then we will see more and more of these consumer electronic and device interactions,” senior author Michael Wu, MD, Brown University, Providence, R.I., told this news organization.

In a May advisory on these device interactions, the U.S. Food and Drug Administration also cautioned that the number of consumer electronics with strong magnets is expected to increase over time.

That trend appears to be already underway, with Forbes reporting in February that the MagSafe batteries will be “getting stronger” as part of upgrades to the iPhone 13 and Bloomberg reporting in advance of Apple’s annual developers conference this week that an upgraded version of MagSafe is in the works to support wireless charging for its iPad. MagSafe has not been used previously in iPads.

Although Apple has acknowledged that the iPhone 12 contains more magnets than previous iPhone models, it says “they’re not expected to pose a greater risk of magnetic interference to medical devices than prior iPhone models.” The company maintains a page that specifically warns about the potential for interactions and advises that consumers keep the iPhone and MagSafe accessories more than 15 cm (6 inches) away from medical devices.

Older-generation iPhones have not shown this risk, with only one case of interference reported with the iPhone 6 and an Apple Watch in 1,352 tests among 148 patients with CIEDs and leads from four different manufacturers.

In the present study, magnet reversion mode was triggered in all three patients when the iPhone 12 Pro Max was placed on the skin over the device.

The phone inhibited tachycardia therapies in Medtronic’s Amplia MRI Quad CRT-D and Abbott’s 1231-40 Fortify VR device.

The Boston Scientific V273 Intua CRT-P device, however, “appeared to be less susceptible, as we were only able to elicit transient temporary asynchronous pacing but no sustained response by the iPhone 12 Pro Max magnet,” Dr. Wu and colleagues note.

Among the 11 ex vivo CIEDs tested, placing the iPhone 12 Pro Max directly over the packaged device inhibited tachytherapies in Medtronic’s Visia AF MRI ICD and Abbott’s Fortify Assura DR ICD and Ellipse DR ICD.

The phone also led to asynchronous pacing in Medtronic’s Azure, Advisa MRI, and Adapta pacemakers and in Abbott’s Assurity MRI pacemaker.

Boston Scientific devices again “appeared to be less susceptible, as no clear magnet interference” was noted in the Dynagen ICD, Emblem MRI S-ICD, or Accolade MRI pacemaker, Dr. Wu reported. There was temporary asynchronous pacing but no sustained response in the company’s U125 Valitude pacemaker.

Using the Medtronic Visia AF MRI ICD, the researchers found that the iPhone 12 Pro Max was able to trigger magnet reversion mode at a distance up to 1.5 cm (0.6 inch) from the anterior aspect of the device ex vivo.

The difference in magnet response to the iPhone 12 Pro Max among the different devices is likely due to different hall-sensor magnet sensitivity, as all of the devices were susceptible to a standard donut magnet, Dr. Wu noted. Boston Scientific’s Accolade MRI pacemaker, for example, requires a magnet stronger than 70 G to activate magnet mode, according to the product manual.

“Even so, sometimes with our test, we were able to trigger a brief response,” he said. “The response isn’t as lasting as some of the other companies, but with the small sample size, I can only speculate and suggest that maybe it’s possible. But we always want a formal study through the company or other agencies to really pinpoint which company has more susceptible devices.”

As to whether manufacturers should build CIEDs less susceptible to today’s stronger magnets, Dr. Wu said it’s worth exploring, but there are pros and cons.

Although magnets in consumer devices have the potential to inhibit lifesaving therapies, a magnet is also very useful in certain medical settings, such as a quick way to ensure pacing without worrying about electrocautery noise during surgery or to deactivate a defibrillator if there’s noise resulting in inappropriate shocks.

“It would require an overhaul of a lot of the devices going forward, and I think that’s something that’s worth exploring, especially now that a lot of devices are using wireless communication, Bluetooth, and other communication technology,” he said.

Even though the study is small, Dr. Wu said, it does represent many of the available devices and has clinical implications, given that people often put their smartphones in a breast pocket.

“This report highlights the importance of public awareness regarding an interaction between CIEDs and a recently released smartphone model with magnetic charging capability,” Dr. Wu and colleagues conclude.

Apple was contacted for comment but had not responded at press time.

The authors reported no study funding or relevant conflicts of interests.

That trend appears to be already underway, with Forbes reporting in February that the MagSafe batteries will be “getting stronger” as part of upgrades to the iPhone 13 and Bloomberg reporting in advance of Apple’s annual developers conference this week that an upgraded version of MagSafe is in the works to support wireless charging for its iPad. MagSafe has not been used previously in iPads.

Although Apple has acknowledged that the iPhone 12 contains more magnets than previous iPhone models, it says “they’re not expected to pose a greater risk of magnetic interference to medical devices than prior iPhone models.” The company maintains a page that specifically warns about the potential for interactions and advises that consumers keep the iPhone and MagSafe accessories more than 15 cm (6 inches) away from medical devices.

Older-generation iPhones have not shown this risk, with only one case of interference reported with the iPhone 6 and an Apple Watch in 1,352 tests among 148 patients with CIEDs and leads from four different manufacturers.

In the present study, magnet reversion mode was triggered in all three patients when the iPhone 12 Pro Max was placed on the skin over the device.

The phone inhibited tachycardia therapies in Medtronic’s Amplia MRI Quad CRT-D and Abbott’s 1231-40 Fortify VR device.

The Boston Scientific V273 Intua CRT-P device, however, “appeared to be less susceptible, as we were only able to elicit transient temporary asynchronous pacing but no sustained response by the iPhone 12 Pro Max magnet,” Dr. Wu and colleagues note.

Among the 11 ex vivo CIEDs tested, placing the iPhone 12 Pro Max directly over the packaged device inhibited tachytherapies in Medtronic’s Visia AF MRI ICD and Abbott’s Fortify Assura DR ICD and Ellipse DR ICD.

The phone also led to asynchronous pacing in Medtronic’s Azure, Advisa MRI, and Adapta pacemakers and in Abbott’s Assurity MRI pacemaker.

Boston Scientific devices again “appeared to be less susceptible, as no clear magnet interference” was noted in the Dynagen ICD, Emblem MRI S-ICD, or Accolade MRI pacemaker, Dr. Wu reported. There was temporary asynchronous pacing but no sustained response in the company’s U125 Valitude pacemaker.

Using the Medtronic Visia AF MRI ICD, the researchers found that the iPhone 12 Pro Max was able to trigger magnet reversion mode at a distance up to 1.5 cm (0.6 inch) from the anterior aspect of the device ex vivo.

The difference in magnet response to the iPhone 12 Pro Max among the different devices is likely due to different hall-sensor magnet sensitivity, as all of the devices were susceptible to a standard donut magnet, Dr. Wu noted. Boston Scientific’s Accolade MRI pacemaker, for example, requires a magnet stronger than 70 G to activate magnet mode, according to the product manual.

“Even so, sometimes with our test, we were able to trigger a brief response,” he said. “The response isn’t as lasting as some of the other companies, but with the small sample size, I can only speculate and suggest that maybe it’s possible. But we always want a formal study through the company or other agencies to really pinpoint which company has more susceptible devices.”

As to whether manufacturers should build CIEDs less susceptible to today’s stronger magnets, Dr. Wu said it’s worth exploring, but there are pros and cons.

Although magnets in consumer devices have the potential to inhibit lifesaving therapies, a magnet is also very useful in certain medical settings, such as a quick way to ensure pacing without worrying about electrocautery noise during surgery or to deactivate a defibrillator if there’s noise resulting in inappropriate shocks.

“It would require an overhaul of a lot of the devices going forward, and I think that’s something that’s worth exploring, especially now that a lot of devices are using wireless communication, Bluetooth, and other communication technology,” he said.

Even though the study is small, Dr. Wu said, it does represent many of the available devices and has clinical implications, given that people often put their smartphones in a breast pocket.

“This report highlights the importance of public awareness regarding an interaction between CIEDs and a recently released smartphone model with magnetic charging capability,” Dr. Wu and colleagues conclude.

Apple was contacted for comment but had not responded at press time.

The authors reported no study funding or relevant conflicts of interests.

People with migraines appeared to have a higher likelihood of COVID-19 infection and subsequent symptoms of the disease, but they were less likely to receive health care, according to a study presented at the American Headache Society’s 2021 annual meeting.

“These data suggest that people with migraine are either more susceptible to contracting COVID-19, or that they may be more sensitive to the development of symptoms once COVID-19 has been contracted, or both,” Robert Shapiro, MD, PhD, professor of neurological science at the University of Vermont, Burlington. “Further, once COVID-19 has been contracted, people with migraine may be less likely to develop serious COVID-19 outcomes, or they may be less likely to seek health care for COVID-19, or both.”

In providing background information, Dr. Shapiro noted previous research showing that headache is associated with a positive prognosis in COVID-19 inpatients, including lower IL-6 levels throughout the disease course, a 1-week shorter disease course, and a 2.2 times greater relative risk of survival.

Yet in a study across 171 countries, a higher population prevalence of migraine is associated with higher COVID-19 mortality rates. It’s unclear what conclusions can be drawn from that association, however, said Deborah I. Friedman, MD, MPH, professor of neurology and ophthalmology at University of Texas, Dallas, who was not involved in the research.

Dr. Shapiro suggested a theoretical possibility, noting that two genes linked to migraine susceptibility – SCN1A and IFNAR2 – are among 15 host loci also associated with COVID-19 outcomes. Further, Dr. Shapiro noted in his background information, COVID-19 is linked to lower serum calcitonin gene-related peptide levels.

For the study, Dr. Shapiro and colleagues analyzed data from U.S. adults who responded to the National Health and Wellness Survey from April to July 2020. The researchers limited their analysis to the 41,155 participants who had not received the flu vaccine in 2020 since previous research has suggested reduced morbidity among those with COVID-19 who had been vaccinated against the flu. In this group, 4,550 participants had ever been diagnosed by a doctor with migraine (11%) and 36,605 participants had not (89%).

The majority of those with a history of migraine were female (78%), compared with the overall sample (50% female), and tended to be younger, with an average age of 39 compared with 45 for those without migraine (P < .001).

Among those with a previous migraine diagnosis, 3.8% self-reported having had a COVID-19 infection, compared with infection in 2.4% of those without a history of migraine (P < .001). That translated to a 58% increased risk of COVID-19 infection in those with migraine history, with a similar rate of test positivity in both groups (33.7% with migraine history vs. 34.5% without). Test negativity was also similar in both groups (15.9% vs. 17.8%).

Of 360 respondents who had tested positive for COVID-19, the 60 with a history of migraine reported more frequent symptoms than those without migraine. The increased frequency was statistically significant (P < .001 unless otherwise indicated) for the following symptoms:

• Difficulty breathing or shortness of breath (P = .005).
• Fever.
• Headache, sore throat, and/or congestion.
• Fatigue.
• Loss of smell and taste.
• Chills and body aches.
• Persistent pain or pressure in the chest.
• Confusion or inability to arouse.
• Digestive issues (P = .005).
• Bluish lips or face.

For several of these symptoms – such as headache/sore throat/congestion, persistent pain or pressure in the chest, confusion/inability to arouse, and digestive issues – more than twice as many respondents with migraine reported the symptom, vs. those without migraine.
 

Changes in health care utilization

“I think that people with migraine are aware of their bodies and aware of their symptoms more than the average person,” Dr. Friedman said. Yet those with migraine were less likely to use health care while diagnosed with COVID-19 than were those without migraine. Migraine sufferers with a COVID-19 infection were 1.2 times more likely to visit a health care provider than were those without an infection, but the similar relative risk was 1.35 greater for those with COVID-19 infections and no migraines.

Similarly, those with a migraine history were more than twice as likely to visit the emergency department when they had a COVID-19 vaccine infection than were those without an infection (RR = 2.6), but among those without a history of migraine, respondents were nearly five times more likely to visit the emergency department when they had a COVID-19 infection than when they didn’t (RR = 4.9).

Dr. Friedman suggested that the lower utilization rate may have to do with the nature of migraine itself. “There are people with migraine who go to the emergency room all the time, but then there’s most of the people with migraine, who would rather die than go to the emergency room because with the light and the noise, it’s just a horrible place to be if you have migraine,” Dr. Friedman said. “I think the majority of people would prefer not to go to the emergency room if given the choice.”

Increased likelihood of hospitalization among those with migraine and a COVID-19 infection was 4.6 compared with those with a migraine and no infection; the corresponding hospitalization risk for COVID-19 among those without migraine was 7.6 times greater than for those with no infection. All these risk ratios were statistically significant.

Dr. Shapiro then speculated on what it might mean that headache is a positive prognostic indicator for COVID-19 inpatients and that migraine population prevalence is linked to higher COVID-19 mortality.

“A hypothesis emerges that headache as a symptom, and migraine as a disease, may reflect adaptive processes associated with host defenses against viruses,” Dr. Shapiro said. “For example, migraine-driven behaviors, such as social distancing due to photophobia, in the setting of viral illness may play adaptive roles in reducing viral spread.”

The researchers did not receive external funding. Dr. Shapiro has consulted for Eli Lilly and Lundbeck. Dr. Friedman reports grant support and/or advisory board participation for Allergan, Biohaven Pharmaceuticals, Eli Lilly, Impel NeuroPharma, Invex, Lundbeck, Merck, Revance Therapeutics, Satsuma Pharmaceuticals, Teva Pharmaceuticals, Theranica, and Zosano Pharma.

Veterans with chronic headaches had a greater risk of a suicide attempt than that of veterans suffering from chronic neck or back pain, according to findings presented at the American Headache Society’s 2021 annual meeting. Risk rose even more in those with chronic headache pain and a comorbid traumatic brain injury (TBI).

“In addition, as expected, veterans with psychiatric conditions have increased risk of suicide attempt with the exception of anxiety in men and dependent personality in women,” said X. Michelle Androulakis, MD, associate professor of neurology at the University of South Carolina, Columbia.
 

‘Surprising’ findings

“These findings are eye-opening but not surprising since we know that veterans in general and people with chronic pain are at higher risk for suicidal behaviors compared with their civilian counterparts,” said Amy. S Grinberg, PhD, a clinical health psychologist who practices in New Rochelle, N.Y. Dr. Grinberg, who also works at VA Connecticut Healthcare System, was not involved in the study.

“It is, however, very interesting that suicidal attempts are higher in veterans with chronic headache compared with other chronic pain disorders, such as chronic neck and back pain,” Dr Grinberg said. “This really highlights the impact of living with a chronic headache disorder, and emphasizes the continued efforts that should be put into place to support veterans with chronic headache, including improved access to a range of treatment options and continued funding for future research.”
 

Veterans with chronic pain

The researchers retrospectively analyzed Veterans Health Administration electronic health records of 3,252,704 veterans, predominantly male and White, who had been diagnosed with any type of chronic pain from 2000 to 2010.

The researchers looked at overall headache diagnoses instead of specific diagnoses, such as migraine, cluster headache, or posttraumatic headache, since specific headache disorders are frequently underdiagnosed.

The population included 14.7% of patients with chronic headache, 14.9% with chronic neck pain, 59.2% with chronic back pain, and 60.2% with other types of chronic pain, including arthritis, fibromyalgia, joint pain, and reflex sympathetic dystrophy.

Traumatic brain injury occurred in 11.2% of those with chronic headaches, compared with 6.8% of those with chronic back pain, 8.5% of those with chronic neck pain, and 5.9% of those with other chronic pain.

More than half (56.4%) of those with chronic headache had depression, the most common comorbidity in the group, followed by 31.5% who had posttraumatic stress disorder (PTSD), and 21.8% who had adjustment disorder. Other rates of psychiatric disorders were all below 10%. Prevalence of depression occurred in 44.5% of those with back pain, 52.4% of those with neck pain, and 39% of those with other chronic pain. PTSD rates were also lower in those with back (22%), neck (27.2%), or other chronic pain (18.6%).

“Interestingly, this study found that those veterans with a history of traumatic brain injury and psychiatric comorbidities, such as depression, are at greater risk for suicide attempts,” said Dr. Grinberg. “The good news is that these are modifiable risk factors, and evidence-based treatments for depression, PTSD, and headache, for example, are widely disseminated within the VA.”

The majority of headache diagnoses were not otherwise specified (80.1%). Half (50.2%) were migraine headaches while rates were much lower for tension-type headache (8.8%), trigeminal neuralgia (5%), cluster headache (0.8%), and posttraumatic headache (0.7%).

The highest incidence of suicide attempts occurred among those with chronic headaches, ranging from 329 to 396 per 100,000, aside from a peak of 482 per 100,000 in 2005. Suicide attempts peaked among all patients with chronic pain in 2005, “likely related to the deployment and policy changes in the Veterans Health Administration,” Dr. Androulakis said.

Those with neck pain had the next highest rate of suicide attempts, ranging from 263 to 314 per 100,000, excluding the peak of 398 per 100,000 in 2005.

Male veterans with chronic headaches had a 1.5 times greater likelihood of a suicide attempt than did those with back or neck pain (relative risk [RR] = 1.5), which increased to a relative risk of 2.8 greater for those with concurrent TBI. Among female veterans, chronic headache was associated with a 1.6 times greater risk of a suicide attempt, which rose to 2.15 times greater with concurrent TBI.

“Knowing that veterans with chronic headache disorders have an elevated rate of suicide, it is imperative that doctors and other clinical providers continue to conduct in-depth risk assessments and implement strategies to support those veterans who are at risk,” said Dr. Grinberg. “Clinical providers should continue in their efforts to reduce stigma associated with headache disorders and mental health treatment in order to effectively engage veterans in evidence-based treatments that are likely a step towards reducing symptoms and suicidal attempts.”

No external funding was noted. Dr. Androulakis and Dr. Grinberg had no disclosures.

S Grinberg, PhD, a clinical health psychologist who practices in New Rochelle, N.Y. Dr. Grinberg, who also works at VA Connecticut Healthcare System, was not involved in the study.

“It is, however, very interesting that suicidal attempts are higher in veterans with chronic headache compared with other chronic pain disorders, such as chronic neck and back pain,” Dr Grinberg said. “This really highlights the impact of living with a chronic headache disorder, and emphasizes the continued efforts that should be put into place to support veterans with chronic headache, including improved access to a range of treatment options and continued funding for future research.”
 

Veterans with chronic pain

The researchers retrospectively analyzed Veterans Health Administration electronic health records of 3,252,704 veterans, predominantly male and White, who had been diagnosed with any type of chronic pain from 2000 to 2010.

The researchers looked at overall headache diagnoses instead of specific diagnoses, such as migraine, cluster headache, or posttraumatic headache, since specific headache disorders are frequently underdiagnosed.

The population included 14.7% of patients with chronic headache, 14.9% with chronic neck pain, 59.2% with chronic back pain, and 60.2% with other types of chronic pain, including arthritis, fibromyalgia, joint pain, and reflex sympathetic dystrophy.

Traumatic brain injury occurred in 11.2% of those with chronic headaches, compared with 6.8% of those with chronic back pain, 8.5% of those with chronic neck pain, and 5.9% of those with other chronic pain.

More than half (56.4%) of those with chronic headache had depression, the most common comorbidity in the group, followed by 31.5% who had posttraumatic stress disorder (PTSD), and 21.8% who had adjustment disorder. Other rates of psychiatric disorders were all below 10%. Prevalence of depression occurred in 44.5% of those with back pain, 52.4% of those with neck pain, and 39% of those with other chronic pain. PTSD rates were also lower in those with back (22%), neck (27.2%), or other chronic pain (18.6%).

“Interestingly, this study found that those veterans with a history of traumatic brain injury and psychiatric comorbidities, such as depression, are at greater risk for suicide attempts,” said Dr. Grinberg. “The good news is that these are modifiable risk factors, and evidence-based treatments for depression, PTSD, and headache, for example, are widely disseminated within the VA.”

The majority of headache diagnoses were not otherwise specified (80.1%). Half (50.2%) were migraine headaches while rates were much lower for tension-type headache (8.8%), trigeminal neuralgia (5%), cluster headache (0.8%), and posttraumatic headache (0.7%).

The highest incidence of suicide attempts occurred among those with chronic headaches, ranging from 329 to 396 per 100,000, aside from a peak of 482 per 100,000 in 2005. Suicide attempts peaked among all patients with chronic pain in 2005, “likely related to the deployment and policy changes in the Veterans Health Administration,” Dr. Androulakis said.

Those with neck pain had the next highest rate of suicide attempts, ranging from 263 to 314 per 100,000, excluding the peak of 398 per 100,000 in 2005.

Male veterans with chronic headaches had a 1.5 times greater likelihood of a suicide attempt than did those with back or neck pain (relative risk [RR] = 1.5), which increased to a relative risk of 2.8 greater for those with concurrent TBI. Among female veterans, chronic headache was associated with a 1.6 times greater risk of a suicide attempt, which rose to 2.15 times greater with concurrent TBI.

“Knowing that veterans with chronic headache disorders have an elevated rate of suicide, it is imperative that doctors and other clinical providers continue to conduct in-depth risk assessments and implement strategies to support those veterans who are at risk,” said Dr. Grinberg. “Clinical providers should continue in their efforts to reduce stigma associated with headache disorders and mental health treatment in order to effectively engage veterans in evidence-based treatments that are likely a step towards reducing symptoms and suicidal attempts.”

No external funding was noted. Dr. Androulakis and Dr. Grinberg had no disclosures.

Music has to be one of humanity’s most unique traits, and, at the same time, one of neurology’s greatest mysteries.

Where did it come from, and why? Rhythmic sounds are part of the universe, from heartbeats to spinning pulsars. Somehow, though, they became ingrained into the very structure of our brains to where having music around is part of our existence.

When it started, we can only guess. The first known musical instrument is a flute carved from bear bone, made 67,000 years ago, but music is certainly older. The first instruments were probably clapped hands, then rocks and sticks.

Tens of thousands of cultures have developed over the course of human history. And, to date, not a single one is known that didn’t have music.

It takes energy to create music, too: to make and play instruments, think of songs, sing ... So at some point having music became an evolutionary advantage of some sort (one can imagine Bill and Ted saying “Dude, chicks dig it”) or it wouldn’t have lasted. Then, as people spread out, music forms got mixed and matched among cultures. Always changing, never leaving, and now somehow woven into the DNA of our brains.

The physics principles behind music are limited and simple: percussion, a vibrating string, air movement in a tube ... But from such simple things the human brain has adapted thousands of natural, and now synthetic, objects, to create an endless variety of unique sounds.

There are plenty of articles out there about how music can be relaxing or stimulating, capable of distracting you or helping you concentrate. Music can help you forget a bad day or remember a good one. They talk about PET scans and cortical activation and many other interesting things that show the effect of music on the remarkable human brain.

But at some level it doesn’t matter to me. I don’t try to understand music any more than I try to understand my dogs. I just know I couldn’t live without either. I’m not alone. Look around you: How many people on the train, or plane, or in the gym have earbuds on?

I have iTunes on my office computer, with roughly 5,000 songs covering the majority of genres from classical to rock. It’s the first program I switch on early each morning when I start the day. It gets me focused on the work at hand, and adds an enjoyable element to the day.

I’m not a musician. I took a few guitar lessons as a kid, but never really learned it. I used to joke that the only instrument I could play was the stereo (now I guess it’s iTunes). Coming from a maternal line of excellent musicians, it’s embarrassing to admit my lack of talent. But my inability to perform it myself doesn’t keep me from enjoying it.

There is no better example of the remarkable human memory than its ability to instantly recall the lyrics of songs you haven’t heard for 20, 30, 40, or more years. A few notes and it’s like you heard them yesterday. At this point, almost 30 years since my medical school graduation, I’ve likely forgotten a large portion of what I learned there. But 70s or 80s pop from my youth? Still there, and immediately recalled.

We process music everywhere – at stores, in elevators, in the car – without realizing it, like driving down the street and automatically reading signs as we pass them. But no matter where it is in our level of realization at the time, it’s a key part of our everyday lives.

Another marvel of the remarkable human brain.

A phase 3, sham-controlled clinical trial of an external trigeminal nerve stimulation (e-TNS) device showed confirmed superiority over a sham device and eliminated the most bothersome migraine symptoms after 2 hours of use. The study also demonstrated that the device, manufactured by Cefaly and cleared in 2020 by the Food and Drug Administration for over-the-counter use, can be safely and effectively used at home.

The study also explored the benefits of 2 hours of use, rather than the 1 hour of use tested in a previous study. “The programming on the device is currently [set to] turn off at 1 hour. As a result of this study, I tell patients if they don’t have adequate relief, and they’re tolerating it, that they can activate it again for a second hour,” Stewart Tepper, MD, said in an interview. Dr. Tepper is a professor of neurology at Geisel School of Medicine at Dartmouth, Hanover, N.H., and a coauthor of the study that was presented by Deena Kuruvilla, MD, at the American Headache Society’s 2021 annual meeting. Dr. Kuruvilla is a neurologist and director of the Westport (Conn.) Headache Institute.

The improvements seen over the sham were significant but not overwhelming, according to Deborah Friedman, MD, MPH, professor of neurology and ophthalmology at the University of Texas, Dallas.

“The numbers are not super impressive when you compare them with other devices. I thought it was interesting that the most bothersome symptom went away in a much higher percentage of people than the headache. That was actually pretty impressive,” said Dr. Friedman, who was asked to comment on the study. She also wondered if the sham device may have inadvertently provided a small amount of stimulation, which could explain the smaller than expected efficacy difference. “It just kind of makes me wonder because I would expect to see a larger separation, even though it was statistically significant.”

The study was an overall success according to Dr. Tepper, who noted that the efficacy of pain freedom was comparable with what has been seen with calcitonin gene-related peptide receptor antagonists (gepants), as well as relieving the most bothersome symptom at 2 hours. The device failed to reduce the usage of rescue medication, suggesting that it might be a candidate to combine with rescue medications. “I think the main thing is it works. It works in a sham-controlled trial, it works at home, and it works comparably to acute medication. And it is further evidence that the lack of access is something that needs to be addressed,” said Dr. Tepper.

Access will depend on insurance companies, who have so far been reluctant to pay for the device. Dr. Tepper is not optimistic they will come around on their own. “My feeling about it is that the only way that payers will finally start to cover this is with a concerted, organized advocacy campaign by patients. The analogy is that when the disease-modifying therapies became available for multiple sclerosis, the National MS Society organized the MS patients and they demanded that the payers cover the disease modifying therapies. That’s the kind of intense focus of advocacy that needs to be done for these noninvasive neuromodulation devices,” said Dr. Tepper.

The TEAM study was a double blind, randomized, sham-controlled trial of 538 patients who were asked to use neurostimulation for a 2-hour, continuous session within 4 hours of a moderate to severe migraine accompanied by at least one migraine-associated symptom. At 2 hours, 25.5% of those using the device achieved pain freedom, compared with 18.3% of those using the sham (P < .05). Among those using the device, 56.4% had freedom from most bothersome symptom, compared with 42.3% of those using the sham (P < .01).

Pain relief at 2 hours was more common in the device group (69.5% vs. 55.2%; P < .01), as was absence of all migraine-associated symptoms at 2 hours (42.5% vs. 34.1%; P < .05), sustained pain freedom at 24 hours (22.8% vs. 15.8%; P < .05), and sustained pain relief at 24 hours (45.9% vs. 34.4%; P < .01). There was no statistically significant between-group difference in use of rescue medications.

In the device group, 8.5% of patients experienced an adverse event, versus 2.9% in the sham group (P = .004). The only adverse reaction that occurred more frequently in the device group was forehead paresthesia, discomfort, and burning (3.5% vs. 0.4%; P = .009).

The study was funded by Cefaly. Dr. Tepper and Dr. Friedman have no relevant financial disclosures.
