Serum levels of neurofilament light are increased before clinical onset of MS
(MS), according to research published in the January issue of JAMA Neurology. These results lend weight to the idea that MS has a prodromal phase, and this phase appears to be associated with neurodegeneration, according to the authors.
Patients often have CNS lesions of various stages of development at the time of their first demyelinating event, and this finding was one basis for neurologists’ hypothesis of a prodromal phase of MS. The finding that one-third of patients with radiologically isolated syndrome develop MS within 5 years also lends credence to this idea. Diagnosing MS early would enable early treatment that could prevent demyelination and the progression of neurodegeneration.
Researchers compared presymptomatic and symptomatic samples
With this idea in mind, Kjetil Bjornevik, MD, PhD, a member of the neuroepidemiology research group at Harvard TH Chan School of Public Health in Boston, and colleagues evaluated whether serum levels of NfL, a marker of ongoing neuroaxonal degeneration, were increased in the years before and around the time of clinical onset of MS. For their study population, the investigators chose active-duty U.S. military personnel who have at least one serum sample stored in the U.S. Department of Defense Serum Repository. Samples are collected after routine HIV type 1 antibody testing.
Within this population, Dr. Bjornevik and colleagues identified patients with MS who had at least one presymptomatic serum sample. The date of clinical MS onset was defined as the date of the first neurologic symptoms attributable to MS documented in the medical record. The investigators randomly selected two control individuals from the population and matched them to each case by age, sex, race or ethnicity, and dates of sample collection. Eligible controls were on active duty on the date of onset of the matched case.
Dr. Bjornevik and colleagues identified 245 patients with MS. Among this sample, the researchers selected two groups that each included 30 cases and 30 controls. The first group included patients who had provided at least one serum sample before MS onset and one sample within 2 years after MS onset. The second group included cases with at least two presymptomatic serum samples, one of which was collected more than 5 years before MS diagnosis, and the other of which was collected between 2 and 5 years before diagnosis. The investigators handled pairs of serum samples in the same way and assayed them in the same batch. The order of the samples in each pair was arranged at random.
Levels were higher in cases than in controls
About 77% of the population was male. Sixty percent of participants were white, 28% were black, and 6.7% were Hispanic. The population’s mean age at first sample collection was approximately 27 years. Mean age at MS onset was approximately 31 years.
For patients who provided samples before and after the clinical onset of MS, serum NfL levels were higher than in matched controls at both points. Most patients who passed from the presymptomatic stage to the symptomatic stage had a significant increase in serum NfL level (i.e., from a median of 25.0 pg/mL to a median of 45.1 pg/mL). Serum NfL levels at the two time points in controls did not differ significantly. For any given patient, an increase in serum NfL level from the presymptomatic measurement to the symptomatic measurement was associated with an increased risk of MS.
In patients with two presymptomatic samples, serum NfL levels were significantly higher in both samples than in the corresponding samples from matched controls. In cases, the earlier sample was collected at a median of 6 years before clinical onset of MS, and the later sample was collected at a median of 1 year before clinical onset. The serum NfL levels increased significantly between the two points for cases (i.e., a median increase of 1.3 pg/mL per year), but there was no significant difference in serum NfL level between the two samples in controls. A within-patient increase in presymptomatic serum NfL level was associated with an increased risk of MS.
Population included few women
“Our study differs from previous studies on the prodromal phase of MS because these have used indirect markers of this phase, which included unspecific symptoms or disturbances occurring before the clinical onset, compared with a marker of neurodegeneration,” wrote Dr. Bjornevik and colleagues. Initiation of treatment with disease-modifying therapy is associated with reductions in serum NfL levels, and this association could explain why some patients in the current study had higher NfL levels before MS onset than afterward. Furthermore, serum NfL levels are highly associated with levels of NfL in cerebrospinal fluid. “Thus, our findings of a presymptomatic increase in serum NfL not only suggest the presence of a prodromal phase in MS, but also that this phase is associated with neurodegeneration,” wrote the investigators.
The study’s well-defined population helped to minimize selection bias, and the blinded, randomized method of analyzing the serum samples eliminated artifactual differences in serum NfL concentrations. But the small sample size precluded analyses that could have influenced clinical practice, wrote Dr. Bjornevik and colleagues. For example, the researchers could not evaluate distinct cutoffs in serum NfL level that could mark the beginning of the prodromal phase of MS. Nor could they determine whether presymptomatic serum NfL levels varied with age at clinical onset, sex, or race. The small number of women in the sample was another limitation of the study.
The Swiss National Research Foundation and the National Institute of Neurologic Disorders and Stroke funded the study. Several of the investigators received fees from various drug companies that were unrelated to the study, and one researcher received grants from the National Institutes of Health during the study.

The power of an odd couple
The time has come for good men and women to unite and rise up against a common foe. For too long nurses and doctors have labored under the tyranny of a dictator who claimed to help them provide high-quality care for their patients while at the same time cutting their paperwork to nil. But like most autocrats he failed to engage his subjects in a meaningful dialogue as each new version of his promised improvements rolled off the drawing board. When the caregivers were slow to adopt these new nonsystems he offered them financial incentives and issued threats to their survival. Although they were warned that there might be uncomfortable adjustment periods, the caregivers were promised that the steep learning curves would level out and their professional lives would again be valued and productive.
Of course, the dictator is not a single person but a motley and disorganized conglomerate of user- and patient-unfriendly electronic health record nonsystems. Ask almost any nurse or physician for her feelings about computer-based medical record systems, and you will hear tales of long hours, disengagement, and frustration. Caregivers are unhappy at all levels, and patients have grown tired of their nurses and physicians spending most of their time looking at computer screens.
You certainly have heard this all before. But you are hearing it in hospital hallways and grocery store checkout lines as a low rumble of discontent emerging from separate individuals, not as a well-articulated and widely distributed voice of physicians as a group. To some extent this relative silence is because there is no such group, at least not in same mold as a labor union. The term “labor union” may make you uncomfortable. But given the current climate in medicine, unionizing may be the best and only way to effect change.
But organizing to effect change in the workplace isn’t part of the physician genome. In the 1960s, a group of house officers in Boston engaged in a heal-in to successfully improve their salaries and working conditions. But over the ensuing half century physicians have remained tragically silent in the face of a changing workplace landscape in which they have gone from being independent owner operators in control of their destinies to becoming employees feeling powerless to improve their working conditions. This perceived impotence has escalated in the face of the challenge posed by the introduction of dysfunctional EHRs.
Ironically, a solution is at almost every physician’s elbow. In a recent New York Times opinion piece Theresa Brown and Stephen Bergman acknowledge that physicians don’t seem prepared to mount a meaningful response to the challenge to the failed promise of EHRs (“Doctors, Nurses and the Paperwork Crisis That Could Unite Them,” Dec. 31, 2019). They point out that, over the last half century, physicians have remained isolated on the sidelines, finding just enough voice to grumble. Nurses have in a variety of situations organized to effect change in their working conditions – in some cases by forming labor unions.
The authors of this op-ed piece, a physician and a nurse, make a strong argument that the time has come for nurses and doctors shake off the shackles of their stereotypic roles and join in creating a loud, forceful, and effective voice to demand a working environment in which the computer functions as an asset and no longer as the terrible burden it has become. Neither group has the power to do it alone, but together they may be able to turn the tide. For physicians it will probably mean venturing several steps outside of their comfort zone. But working shoulder to shoulder with nurses may provide the courage to speak out.

FDA issues public health warning recommending against cesium salt usage
The Food and Drug Administration has issued a public health alert warning consumers to avoid the use of dietary supplements that contain cesium chloride or any other cesium salt because of significant safety risks.
Cesium salts are sometimes advertised as an alternative treatment for cancer, the FDA said in the announcement, but these salts have never proved to be safe or effective at treating cancer or any other disease. Clinical case reports and nonclinical trials have shown that cesium salts are associated with a variety of adverse events, including cardiac arrhythmias, hypokalemia, seizures, syncope, and death.
The FDA warned health care providers that cesium salts presented a significant safety risk in compounding drugs in July 2018.
Health care providers should not recommend dietary supplements containing cesium salts to their patients, the FDA said, and if a patient experiences an adverse event while taking a supplement containing cesium salt, the event should be reported to the agency.
While there are few dietary supplements on the market that contain cesium salt, consumers should be aware of the risks and avoid these products. The FDA noted that “if claims sound too good to be true, they probably are.”

How much exercise is needed for maximum heart benefit?
SNOWMASS, COLO. – Physical activity is potent medicine, and it doesn’t take all that much of it to derive the maximum cardiovascular benefit: namely, the equivalent of a brisk hour-long walk 5 days/week or jogging at a 10-minute-per-mile pace for half an hour twice weekly, Robert A. Vogel, MD, asserted at the annual Cardiovascular Conference at Snowmass sponsored by the American College of Cardiology.
“I’m not telling you to run marathons. said Dr. Vogel, a cardiologist at the University of Colorado at Denver, Aurora, with a longstanding interest in preventive cardiology.
He presented selected highlights from the massive evidence base underlying the recommendations put forth in the current comprehensive U.S. Department of Health & Human Services Physical Activity Guidelines for Americans.
One particularly compelling chunk of evidence comes from a Taiwanese government–funded prospective cohort study of more than 416,000 individuals followed for an average of 8 years. A key finding: 15 minutes of moderate-intensity physical activity daily was associated with a 14% reduction in the relative risk of all-cause mortality and a 19% reduction in death caused by cardiovascular disease, compared with that of inactive individuals. Moreover, each additional 15 minutes of daily moderate exercise further reduced mortality by 4%. These benefits extended across the full age spectrum of both sexes and applied to patients with cardiovascular disease (Lancet. 2011 Oct 1;378[9798]:1244-53).
“That’s a very impressive result for modest physical activity,” the cardiologist commented.
Data on more than 50,000 adult participants in the Aerobics Center Longitudinal Study based at the Cooper Clinic in Dallas show that vigorous exercise in the form of running at 6 mph for half an hour twice weekly, or a total of 10 metabolic equivalent of task hours (MET-HR) per week, was associated with a roughly 40% reduction in cardiovascular disease mortality. Importantly, 20, 40, or 50 MET-HR/week of vigorous exercise conferred no further survival benefit (J Am Coll Cardiol. 2014 Aug 5;64[5]:472-81). The same group showed that the sweet spot for moderate physical activity in terms of reduced cardiovascular mortality was brisk walking for an hour daily 5 days/week, for a total of 20 MET-HR, which was also associated with roughly a 40% risk reduction compared to inactivity. At that point the benefit plateaued, with no further mortality reduction noted with additional MET-HR of moderate exercise.
“For more than that, we have no evidence of additional cardiovascular benefit. It’s not going to get you to the Tokyo Olympics, but that’s what we need to be doing,” Dr. Vogel observed.
In another report from the Aerobics Center Longitudinal Study, investigators found that moderate-level cardiorespiratory fitness as defined by METs was associated with a 44% reduction in the risk of sudden cardiac death in men and women after adjustment for potential confounders, while high-level cardiorespiratory fitness was associated with a closely similar 48% reduction in risk. This applied to individuals who were hypertensive, overweight, and/or had poor health status, as well as to others (Mayo Clin Proc. 2016 Jul;91[7]:849-57).
All activity counts
Exercise physiologists speak of NEPA – nonexercise physical activity – such as taking out the garbage. Swedish investigators followed more than 4,200 individuals for an average of 12.5 years and found that high NEPA activity was independently associated with a 30% reduction in all-cause mortality and a 27% lower risk of a first cardiovascular disease event, compared with low NEPA. High NEPA in regular exercisers was associated with a lower rate of metabolic syndrome than in low-NEPA regular exercisers (Br J Sports Med. 2014 Feb;48[3]:233-8).
Don’t just sit there – stand!
The current federal physical activity guidelines place a new emphasis on the detrimental effects of sitting. A report on more than 221,000 participants in the Australian 45 and Up Study, with close to 1 million person-years of follow-up, demonstrated a linear inverse relationship between standing time per day and all-cause mortality. In a multivariate analysis adjusted for potential confounders, individuals who stood for 2-5 hours per day had a 10% lower risk of all-cause mortality than did those who stood for less than 2 hours. Standing for 5-8 hours was associated with a 15% relative risk reduction. And standing for more than 8 hours daily was linked to a 24% reduction in risk (Prev Med. 2014 Dec;69:187-91).
And it’s not just total daily sitting time that’s a risk factor. Prolonged, uninterrupted sedentary time was also associated with a dose-dependent increase in all-cause mortality in a prospective cohort study of nearly 8,000 U.S. adults (Ann Intern Med. 2017 Oct 3;167[7]:465-75).
“If you can’t walk around, talk to your patients standing up. That activity of getting out of your chair is lifesaving,” the cardiologist advised.
Get strong
Muscle-strengthening activity on at least 2 days/week is recommended in the federal guidelines because it’s independently associated with decreased all-cause mortality, even in individuals getting sufficient aerobic exercise, as shown in a large national study with 15-years’ follow-up (Prev Med. 2016 Jun;87:121-127).
“As we get older, we tend to forget about muscle. I work with the National Football League. These folks are pretty strong, but we never see diabetes in these very big players, who are often well over 300 lb. They’ve got a lot of muscle. If you want to prevent diabetes, be strong. It’s a very important factor,” Dr. Vogel said.
For the time constrained
Jogging is more time-efficient than brisk walking as a way to attain the maximum cardiovascular benefit of exercise. And the so-called “Weekend Warrior” study of nearly 64,000 U.K. adults showed that it’s okay to cram the full week’s worth of exercise into one or two sessions and be done with it. Compared with the inactive study participants, the weekend warriors had a 40% reduction in cardiovascular disease mortality, while individuals who split their physical activity up into three or more sessions per week had a nearly identical 41% relative risk reduction (JAMA Intern Med. 2017 Mar 1;177[3]:335-42).
Interval training is a standard way for athletes in training to improve their endurance by alternating short, intense exercise with brief recovery periods. It’s also a time saver: In one classic bicycling study, physically active men were randomized to standardized 2-week programs of sprint interval training or high-volume endurance training on the bike. The training time required to pass a rigorous cycling time trial test was 90% lower in the interval training group (J Physiol. 2006 Sep 15;575(Pt 3):901-11).
The same principle is applicable to the nonathlete interested in physical activity for heart health.
“When I run a couple of miles, I walk for 5 minutes, then maybe run for three-quarters of a mile, then walk again, then run. In interval training you get your heart rate up, and you drop it down. It’s a very good form of exercise. As a vascular biologist I know that if you put endothelial cells in a Petri dish and spin them real fast continuously, you will not get as good an improvement in endothelial function as if you spin the dish, stop it, spin it, stop it,” Dr. Vogel said.
High-volume exercise is safe, even with high coronary calcium
A clinically significant coronary artery calcification score of 100 Agatston units or more is no reason not to exercise. A Cooper Clinic report on nearly 22,000 middle-aged men without baseline cardiovascular disease who were followed for a mean of 10.4 years concluded that those in the highest-volume exercise group, many of whom were marathon runners and engaged in the equivalent of running for at least 5-6 hours/week at a pace of 10 minutes per mile, were 11% more likely to have an elevated baseline coronary artery calcification score than those who exercised less. But these highest-volume exercisers with elevated coronary calcium – their mean level was 807 Agatston units – had risks of all-cause and cardiovascular mortality that weren’t significantly different from those of men with elevated coronary calcium who exercised more moderately (JAMA Cardiol. 2019 Feb 1;4[2]:174-81).
Cardiac rehab
Dr. Vogel had harsh words for his physician colleagues with respect to the widespread underprescribing of cardiac rehabilitation programs.
“You guys are doing a crappy job with exercise in our most vulnerable patients: those who’ve had cardiovascular events,” he charged. “Cardiac rehabilitation is a Class I recommendation in our guidelines. And yet utilization in the United States is just 10%-20%. No other Class I recommendation is in that ballpark.”
A meta-analysis of 34 randomized trials totaling more than 6,000 post-MI patients concluded that those randomized to exercise-based cardiac rehabilitation had a 47% reduction in the risk of reinfarction, 36% lower cardiac mortality, and a 26% reduction in all-cause mortality (Am Heart J. 2011 Oct;162[4]:571-584.e2).
“The data show that cardiac rehabilitation is as effective as anything else we do in cardiovascular medicine. I understand that patients live far away, they don’t like to exercise – I’ve heard every excuse. But I am charging you with the responsibility of meeting a Class I recommendation that gets patients to live longer,” he declared.
Medicare now covers an enhanced, 72-session program called Intensive Cardiac Rehabilitation that teaches comprehensive lifestyle change and provides reasonable reimbursement. “It’s a good thing for our patients,” Dr. Vogel commented.
Yoga
For patients who are reluctant to pound the pavement, yoga may provide an alternative form of physical activity with tangible cardiovascular benefits. Dr. Vogel pointed to the Yoga-CaRe trial presented at the 2018 scientific sessions of the American Heart Association. Yoga-CaRe randomized 3,959 post-MI patients at 29 centers in India to a program of 13 supervised in-hospital yoga classes followed by yoga at home, or to a control group with three educational sessions. The rate of major adverse cardiovascular events over 42 months of follow-up was cut in half, compared with controls, in the 27% of participants who attended at least 10 of the 13 yoga classes. Their quality of life scores were higher, too.

SNOWMASS, COLO. – Physical activity is potent medicine, and it doesn’t take all that much of it to derive the maximum cardiovascular benefit: namely, the equivalent of a brisk hour-long walk 5 days/week or jogging at a 10-minute-per-mile pace for half an hour twice weekly, Robert A. Vogel, MD, asserted at the annual Cardiovascular Conference at Snowmass sponsored by the American College of Cardiology.
“I’m not telling you to run marathons. said Dr. Vogel, a cardiologist at the University of Colorado at Denver, Aurora, with a longstanding interest in preventive cardiology.
He presented selected highlights from the massive evidence base underlying the recommendations put forth in the current comprehensive U.S. Department of Health & Human Services Physical Activity Guidelines for Americans.
One particularly compelling chunk of evidence comes from a Taiwanese government–funded prospective cohort study of more than 416,000 individuals followed for an average of 8 years. A key finding: 15 minutes of moderate-intensity physical activity daily was associated with a 14% reduction in the relative risk of all-cause mortality and a 19% reduction in death caused by cardiovascular disease, compared with that of inactive individuals. Moreover, each additional 15 minutes of daily moderate exercise further reduced mortality by 4%. These benefits extended across the full age spectrum of both sexes and applied to patients with cardiovascular disease (Lancet. 2011 Oct 1;378[9798]:1244-53).
“That’s a very impressive result for modest physical activity,” the cardiologist commented.
Data on more than 50,000 adult participants in the Aerobics Center Longitudinal Study based at the Cooper Clinic in Dallas show that vigorous exercise in the form of running at 6 mph for half an hour twice weekly, or a total of 10 metabolic equivalent of task hours (MET-HR) per week, was associated with a roughly 40% reduction in cardiovascular disease mortality. Importantly, 20, 40, or 50 MET-HR/week of vigorous exercise conferred no further survival benefit (J Am Coll Cardiol. 2014 Aug 5;64[5]:472-81). The same group showed that the sweet spot for moderate physical activity in terms of reduced cardiovascular mortality was brisk walking for an hour daily 5 days/week, for a total of 20 MET-HR, which was also associated with roughly a 40% risk reduction compared to inactivity. At that point the benefit plateaued, with no further mortality reduction noted with additional MET-HR of moderate exercise.
“For more than that, we have no evidence of additional cardiovascular benefit. It’s not going to get you to the Tokyo Olympics, but that’s what we need to be doing,” Dr. Vogel observed.
In another report from the Aerobics Center Longitudinal Study, investigators found that moderate-level cardiorespiratory fitness as defined by METs was associated with a 44% reduction in the risk of sudden cardiac death in men and women after adjustment for potential confounders, while high-level cardiorespiratory fitness was associated with a closely similar 48% reduction in risk. This applied to individuals who were hypertensive, overweight, and/or had poor health status, as well as to others (Mayo Clin Proc. 2016 Jul;91[7]:849-57).
All activity counts
Exercise physiologists speak of NEPA – nonexercise physical activity – such as taking out the garbage. Swedish investigators followed more than 4,200 individuals for an average of 12.5 years and found that high NEPA activity was independently associated with a 30% reduction in all-cause mortality and a 27% lower risk of a first cardiovascular disease event, compared with low NEPA. High NEPA in regular exercisers was associated with a lower rate of metabolic syndrome than in low-NEPA regular exercisers (Br J Sports Med. 2014 Feb;48[3]:233-8).
Don’t just sit there – stand!
The current federal physical activity guidelines place a new emphasis on the detrimental effects of sitting. A report on more than 221,000 participants in the Australian 45 and Up Study, with close to 1 million person-years of follow-up, demonstrated a linear inverse relationship between standing time per day and all-cause mortality. In a multivariate analysis adjusted for potential confounders, individuals who stood for 2-5 hours per day had a 10% lower risk of all-cause mortality than did those who stood for less than 2 hours.

EXPERT ANALYSIS FROM ACC SNOWMASS 2020
Trump takes on multiple health topics in State of the Union
President Donald J. Trump took on multiple health care issues in his State of the Union address, imploring Congress to avoid the “socialism” of Medicare-for-all, to pass legislation banning late-term abortions, and to protect insurance coverage for preexisting conditions while joining together to reduce rising drug prices.
Mr. Trump said his administration has already been “taking on the big pharmaceutical companies,” claiming that, in 2019, “for the first time in 51 years, the cost of prescription drugs actually went down.”
That statement was called “misleading” by the New York Times because such efforts have excluded some high-cost drugs, and prices had risen by the end of the year, the publication noted in a fact-check of the president’s speech.
A survey issued in December 2019 found that the United States pays the highest prices in the world for pharmaceuticals, as reported by Medscape Medical News.
But the president did throw down a gauntlet for Congress. “Working together, the Congress can reduce drug prices substantially from current levels,” he said, stating that he had been “speaking to Sen. Chuck Grassley of Iowa and others in the Congress in order to get something on drug pricing done, and done properly.
“Get a bill to my desk, and I will sign it into law without delay,” Mr. Trump said.
A group of House Democrats then stood up in the chamber and loudly chanted, “HR3, HR3,” referring to the Lower Drug Costs Now Act, which the House passed in December 2019.
The bill would give the Department of Health & Human Services the power to negotiate directly with drug companies on up to 250 drugs per year, in particular, the highest-costing and most-utilized drugs.
The Senate has not taken up the legislation, but Sen. Grassley (R) and Sen. Ron Wyden (D-Ore.) introduced a similar bill, the Prescription Drug Pricing Reduction Act. It has been approved by the Senate Finance Committee but has not been moved to the Senate floor.
“I appreciate President Trump recognizing the work we’re doing to lower prescription drug prices,” Sen. Grassley said in a statement after the State of the Union. “Iowans and Americans across the country are demanding reforms that lower sky-high drug costs. A recent poll showed 70% of Americans want Congress to make lowering drug prices its top priority.”
Rep. Greg Walden (R-Ore.), the ranking Republican on the House Energy and Commerce Committee, said he believed Trump was committed to lowering drug costs. “I’ve never seen a president lean in further than President Donald Trump on lowering health care costs,” said Rep. Walden in a statement after the speech.
Trump touted his price transparency rule, which he said would go into effect next January, as a key way to cut health care costs.
Preexisting conditions
The president said that since he’d taken office, insurance had become more affordable and that the quality of health care had improved. He also said that he was making what he called an “iron-clad pledge” to American families.
“We will always protect patients with preexisting conditions – that is a guarantee,” Mr. Trump said.
In a press conference before the speech, Speaker of the House Nancy Pelosi (D-Calif.) took issue with that pledge. “The president swears that he supports protections for people with preexisting conditions, but right now, he is fighting in federal court to eliminate these lifesaving protections and every last protection and benefit of the Affordable Care Act,” she said.
During the speech, Rep. G. K. Butterfield (D-N.C.) tweeted “#FactCheck: Claiming to protect Americans with preexisting conditions, Trump and his administration have repeatedly sought to undermine protections offered by the ACA through executive orders and the courts. He is seeking to strike down the law and its protections entirely.”
Larry Levitt, executive vice president for health policy at the Kaiser Family Foundation, pointed out in a tweet that insurance plans that Trump touted as “affordable alternatives” are in fact missing those protections.
“Ironically, the cheaper health insurance plans that President Trump has expanded are short-term plans that don’t cover preexisting conditions,” Mr. Levitt said.
Socialist takeover
Mr. Trump condemned the Medicare-for-all proposals that have been introduced in Congress and that are being backed in whole or in part by all of the Democratic candidates for president.
“As we work to improve Americans’ health care, there are those who want to take away your health care, take away your doctor, and abolish private insurance entirely,” said Mr. Trump.
He said that 132 members of Congress “have endorsed legislation to impose a socialist takeover of our health care system, wiping out the private health insurance plans of 180 million Americans.”
Added Mr. Trump: “We will never let socialism destroy American health care!”
Medicare-for-all has waxed and waned in popularity among voters, with generally more Democrats than Republicans favoring a single-payer system, with or without a public option.
Preliminary exit polls in Iowa that were conducted during Monday’s caucus found that 57% of Iowa Democratic caucus-goers supported a single-payer plan; 38% opposed such a plan, according to the Washington Post.
Opioids, the coronavirus, and abortion
In some of his final remarks on health care, Mr. Trump cited progress in the opioid crisis, noting that, in 2019, drug overdose deaths declined for the first time in 30 years.
He said that his administration was coordinating with the Chinese government regarding the coronavirus outbreak and noted the launch of initiatives to improve care for people with kidney disease, Alzheimer’s, and mental health problems.
Mr. Trump repeated his 2019 State of the Union claim that the government would help end AIDS in America by the end of the decade.
The president also announced that he was asking Congress for “an additional $50 million” to fund neonatal research. He followed that up with a plea about abortion.
“I am calling upon the members of Congress here tonight to pass legislation finally banning the late-term abortion of babies,” he said.
Insulin costs?
In the days before the speech, some news outlets had reported that Mr. Trump and the HHS were working on a plan to lower insulin prices for Medicare beneficiaries, and there were suggestions it would come up in the speech.
At least 13 members of Congress invited people advocating for lower insulin costs as their guests for the State of the Union, Stat reported. Rep. Pelosi invited twins from San Francisco with type 1 diabetes as her guests.
But Mr. Trump never mentioned insulin in his speech.

President Donald J. Trump took on multiple health care issues in his State of the Union address, imploring Congress to avoid the “socialism” of Medicare-for-all, to pass legislation banning late-term abortions, and to protect insurance coverage for preexisting conditions while joining together to reduce rising drug prices.
Mr. Trump said his administration has already been “taking on the big pharmaceutical companies,” claiming that, in 2019, “for the first time in 51 years, the cost of prescription drugs actually went down.”
That statement was called “misleading” by the New York Times because such efforts have excluded some high-cost drugs, and prices had risen by the end of the year, the publication noted in a fact-check of the president’s speech.
A survey issued in December 2019 found that the United States pays the highest prices in the world for pharmaceuticals, as reported by Medscape Medical News.
But the president did throw down a gauntlet for Congress. “Working together, the Congress can reduce drug prices substantially from current levels,” he said, stating that he had been “speaking to Sen. Chuck Grassley of Iowa and others in the Congress in order to get something on drug pricing done, and done properly.
“Get a bill to my desk, and I will sign it into law without delay,” Mr. Trump said.
A group of House Democrats then stood up in the chamber and loudly chanted, “HR3, HR3,” referring to the Lower Drug Costs Now Act, which the House passed in December 2019.
The bill would give the Department of Health & Human Services the power to negotiate directly with drug companies on up to 250 drugs per year, in particular, the highest-costing and most-utilized drugs.
The Senate has not taken up the legislation, but Sen. Grassley (R) and Sen. Ron Wyden (D-Ore.) introduced a similar bill, the Prescription Drug Pricing Reduction Act. It has been approved by the Senate Finance Committee but has not been moved to the Senate floor.
“I appreciate President Trump recognizing the work we’re doing to lower prescription drug prices,” Sen. Grassley said in a statement after the State of the Union. “Iowans and Americans across the country are demanding reforms that lower sky-high drug costs. A recent poll showed 70% of Americans want Congress to make lowering drug prices its top priority.”
Rep. Greg Walden (R-Ore.), the ranking Republican on the House Energy and Commerce Committee, said he believed Trump was committed to lowering drug costs. “I’ve never seen a president lean in further than President Donald Trump on lowering health care costs,” said Rep. Walden in a statement after the speech.
Trump touted his price transparency rule, which he said would go into effect next January, as a key way to cut health care costs.
Preexisting conditions
The president said that since he’d taken office, insurance had become more affordable and that the quality of health care had improved. He also said that he was making what he called an “iron-clad pledge” to American families.
“We will always protect patients with preexisting conditions – that is a guarantee,” Mr. Trump said.
In a press conference before the speech, Speaker of the House Nancy Pelosi (D-Calif.) took issue with that pledge. “The president swears that he supports protections for people with preexisting conditions, but right now, he is fighting in federal court to eliminate these lifesaving protections and every last protection and benefit of the Affordable Care Act,” she said.
During the speech, Rep. G. K. Butterfield (D-N.C.) tweeted “#FactCheck: Claiming to protect Americans with preexisting conditions, Trump and his administration have repeatedly sought to undermine protections offered by the ACA through executive orders and the courts. He is seeking to strike down the law and its protections entirely.”
Larry Levitt, executive vice president for health policy at the Kaiser Family Foundation, pointed out in a tweet that insurance plans that Trump touted as “affordable alternatives” are in fact missing those protections.
“Ironically, the cheaper health insurance plans that President Trump has expanded are short-term plans that don’t cover preexisting conditions,” Mr. Levitt said.
Socialist takeover
Mr. Trump condemned the Medicare-for-all proposals that have been introduced in Congress and that are being backed in whole or in part by all of the Democratic candidates for president.
“As we work to improve Americans’ health care, there are those who want to take away your health care, take away your doctor, and abolish private insurance entirely,” said Mr. Trump.
He said that 132 members of Congress “have endorsed legislation to impose a socialist takeover of our health care system, wiping out the private health insurance plans of 180 million Americans.”
Added Mr. Trump: “We will never let socialism destroy American health care!”
Medicare-for-all has waxed and waned in popularity among voters, with generally more Democrats than Republicans favoring a single-payer system, with or without a public option.
Preliminary exit polls in Iowa that were conducted during Monday’s caucus found that 57% of Iowa Democratic caucus-goers supported a single-payer plan; 38% opposed such a plan, according to the Washington Post.
Opioids, the coronavirus, and abortion
In some of his final remarks on health care, Mr. Trump cited progress in the opioid crisis, noting that, in 2019, drug overdose deaths declined for the first time in 30 years.
He said that his administration was coordinating with the Chinese government regarding the coronavirus outbreak and noted the launch of initiatives to improve care for people with kidney disease, Alzheimer’s, and mental health problems.
Mr. Trump repeated his 2019 State of the Union claim that the government would help end AIDS in America by the end of the decade.
The president also announced that he was asking Congress for “an additional $50 million” to fund neonatal research. He followed that up with a plea about abortion.
“I am calling upon the members of Congress here tonight to pass legislation finally banning the late-term abortion of babies,” he said.

Statin, antihypertensive treatment don’t guarantee healthier lifestyles
When people learn they have enough cardiovascular disease risk to start treatment with a statin or antihypertensive drug, the impact on their healthy-lifestyle choices seems to often be a wash, based on findings from more than 40,000 Finland residents followed for at least 4 years after starting their primary-prevention regimen.
“Patients’ awareness of their risk factors alone seems not to be effective in improving health behaviors,” wrote Maarit J. Korhonen, PhD, and associates in a report published in the Journal of the American Heart Association.
“Initiation of antihypertensive or statin therapy appears to be associated with lifestyle changes, some positive and others negative,” wrote Dr. Korhonen, a pharmacoepidemiologist at the University of Turku (Finland), and associates. This was the first reported study to assess a large-scale and prospectively followed cohort to look for associations between the use of medicines that prevent cardiovascular disease (CVD) and lifestyle changes. Most previous studies of these associations “have been cross sectional and provide no information on potential lifestyle changes during the time window around the initiation of medication use,” they added.
The new study specifically found that, on average, people who began treatment with at least one CVD-prevention medication for the first time were more likely to gain weight and more likely to become less active during the years following their treatment onset. But at the same time, these patients were also more likely to either quit or cut down on their smoking and alcohol consumption, the researchers found.
Their analysis used data from 41,225 people enrolled in the Finnish Public Sector Study, which prospectively began collecting data on a large number of Finland residents in the 1990s. They specifically focused on 81,772 completed questionnaires – collected at 4-year intervals – from people who completed at least two consecutive rounds of the survey during 2000-2013, and who were also at least 40 years old and free of prevalent CVD at the time of their first survey. The participants averaged nearly 53 years of age at their first survey, and 84% were women.
The researchers subdivided the survey responses into 8,837 (11%) people who began a statin, antihypertensive drug, or both during their participation; 26,914 (33%) already on a statin or antihypertensive drug when they completed their first questionnaire; and 46,021 response sets (56%) from people who never began treatment with either drug class. People who initiated a relevant drug began a median of 1.7 years following completion of their first survey, and a median of 2.4 years before their next survey. During follow-up, about 2% of all participants became newly diagnosed with some form of CVD.
The results showed that, after full adjustment for possible confounders, the mean increase in body mass index was larger among those who initiated a CVD-prevention drug, compared with those who did not. Among participants who were obese at entry, those who started a CVD drug had a statistically significant 37% increased rate of remaining obese, compared with those not starting these drugs. Among those who were not obese at baseline, those who began a CVD prevention drug had a statistically significant 82%% higher rate of becoming obese, compared with those not on a CVD-prevention drug. In addition, average daily energy expenditure, a measure of physical activity, showed a statistically significant decline among those who started a CVD drug, compared with those who did not. In contrast, CVD drug initiators had an average 1.85 gram/week decline in alcohol intake, compared with noninitiators, and those who were current smokers at the first survey and then started a CVD drug had a 26% relative drop in their smoking prevalence, compared with those who did not start a CVD drug, both statistically significant differences.
The findings suggest that “patients’ awareness of their risk factors alone seems not to be effective in improving health behaviors,” the authors concluded. “This means that expansion of pharmacologic interventions toward populations at low CVD risk may not necessarily lead to expected benefits at the population level.”
The study received no commercial funding. Dr. Korhonen had no disclosures.

Rate of suicide is higher in people with neurologic disorders
The absolute risk difference is small, but statistically significant. “These findings do not necessarily warrant changing the management of treatment for individual patients,” wrote Annette Erlangsen, PhD, a researcher at the Danish Research Institute for Suicide Prevention in Hellerup, and colleagues. “As with all patients, physicians should be aware of the potential for depression, demoralization, and suicide.”
In addition, dementia, Alzheimer’s disease, and intellectual disabilities may be associated with lower suicide rates, according to the study, which was published in JAMA.
“Plausible mechanisms” could underlie the association between neurologic disease and suicide, the authors wrote. A neurologic diagnosis “may constitute a distressing life event,” and the diseases may have psychological, physical, and psychiatric effects. Patients may see themselves as a burden or have less financial security. In addition, the diseases may entail “communication difficulties, poor sleep, and pain.” Neurologic diseases may alter brain circuitry and functioning and influence aggression and impulsivity. “People with neurologic disorders may also have easier access to toxic medication,” they added.
More than a dozen conditions examined
Prior studies have found associations between neurologic conditions and rates of suicide, but data have been inconclusive or inconsistent for some of the disorders. To examine whether people with neurologic disorders have higher suicide rates, relative to people without these disorders, the researchers conducted a retrospective study. They analyzed data from more than 7.3 million people aged 15 years or older who lived in Denmark between 1980 and 2016. The cohort included more than 1.2 million people with neurologic disorders. The investigators identified neurologic disorders using ICD codes for head injury, stroke, epilepsy, polyneuropathy, diseases of the myoneural junction, Parkinson’s disease, multiple sclerosis, CNS infections, meningitis, encephalitis, amyotrophic lateral sclerosis, Huntington’s disease, dementia, intellectual disability, and other brain disorders. They compared incidence rates using a Poisson regression model and adjusted for time period, sex, age, region, socioeconomic status, comorbidity, self-harm or psychiatric hospitalization prior to a neurologic diagnosis, and whether a person lived alone.
In all, 35,483 people in the cohort died by suicide at an average age of about 52 years; 77.4% were male. About 15% of those who died by suicide had a neurologic disorder. The suicide incidence rate among people with a neurologic disorder was 44.0 per 100,000 person-years, whereas the rate among people without a neurologic disorder was 20.1 per 100,000 person-years.
The adjusted incidence rate ratio for people with a neurologic disorder was 1.8. The rate ratio was highest during the 3 months after diagnosis, at 3.1. Huntington’s disease and amyotrophic lateral sclerosis were associated with “the largest excess adjusted [incidence rate ratios] of suicide mortality,” with a rate ratio of 4.9 for each condition, the researchers reported. The adjusted incidence rate ratio was 1.7 for head injury, 1.3 for stroke, 1.7 for epilepsy, 1.4 for intracerebral hemorrhage, 1.3 for cerebral infarction, 1.3 for subarachnoid hemorrhage, 1.7 for polyneuropathy and peripheral neuropathy, 2.2 for Guillain-Barré syndrome, 1.9 for diseases of myoneural junction and muscle, 1.8 for other brain disorders, 1.7 for Parkinson’s disease, 2.2 for multiple sclerosis, and 1.6 for CNS infection.
Compared with people without a neurologic condition, people with dementia, Alzheimer’s disease, and intellectual disabilities had lower suicide rates, with adjusted incidence rate ratios of 0.8, 0.2, and 0.6, respectively. “However, the adjusted [incidence rate ratio] for people with dementia during the first month after diagnosis was 3.0,” the researchers wrote.
In addition, the suicide rate increased with an increasing cumulative number of hospital contacts for neurologic conditions.
Overall incidence rates declined
“Over the study period, the suicide incidence rate for people with neurological disorders decreased from 78.6 per 100,000 person-years during the 1980-1999 years to 27.3 per 100,000 person-years during the 2000-2016 years,” wrote Dr. Erlangsen and colleagues. “The suicide incidence rate for those without a disorder decreased from 26.3 to 12.7 during the same time spans. ... The decline in the overall suicide rate over time did not affect the relative risk pattern.”
The decline in the general suicide rate in Denmark “has largely been attributed to means restriction, such as efforts to limit availability of firearms and particularly toxic medication,” the authors added.
In those time spans, the adjusted incidence rate ratio for suicide among those with dementia decreased from 2.4 to 1.0, and among those with multiple sclerosis from 2.0 to 1.0. “It is possible that the improvements observed for dementia and multiple sclerosis may be related to improvements in treatment and intensified community-based support,” Dr. Erlangsen and coauthors wrote.
When the researchers used people with rheumatoid arthritis as a reference group, those with a neurologic disorder had a higher suicide rate per 100,000 person-years, 30.2 versus 18.4. The adjusted incidence rate ratio for that comparison was 1.4.
In patients with Huntington’s disease, depression mediated by hyperactivity in the hypothalamic-pituitary-adrenal axis may contribute to the risk of suicide. “Witnessing the course of the disease in one’s parent” also may contribute the risk, the researchers wrote.
The analysis may have missed people with neurologic disorders diagnosed before 1977 if they did not have subsequent contact with a hospital, the investigators noted. In addition, diagnoses given in primary care were not included, suicide deaths may be underrecorded, and “adjusting for preexisting mental disorders could be viewed as overadjusting,” they wrote.
The study was supported by a grant from the Psychiatric Research Foundation in Denmark. The authors reported that they had no disclosures.

The adjusted incidence rate ratio was 1.7 for head injury, 1.3 for stroke, 1.7 for epilepsy, 1.4 for intracerebral hemorrhage, 1.3 for cerebral infarction, 1.3 for subarachnoid hemorrhage, 1.7 for polyneuropathy and peripheral neuropathy, 2.2 for Guillain-Barré syndrome, 1.9 for diseases of myoneural junction and muscle, 1.8 for other brain disorders, 1.7 for Parkinson’s disease, 2.2 for multiple sclerosis, and 1.6 for CNS infection.
Compared with people without a neurologic condition, people with dementia, Alzheimer’s disease, and intellectual disabilities had lower suicide rates, with adjusted incidence rate ratios of 0.8, 0.2, and 0.6, respectively. “However, the adjusted [incidence rate ratio] for people with dementia during the first month after diagnosis was 3.0,” the researchers wrote.
In addition, the suicide rate increased with an increasing cumulative number of hospital contacts for neurologic conditions.
Overall incidence rates declined
“Over the study period, the suicide incidence rate for people with neurological disorders decreased from 78.6 per 100,000 person-years during the 1980-1999 years to 27.3 per 100,000 person-years during the 2000-2016 years,” wrote Dr. Erlangsen and colleagues. “The suicide incidence rate for those without a disorder decreased from 26.3 to 12.7 during the same time spans. ... The decline in the overall suicide rate over time did not affect the relative risk pattern.”
The decline in the general suicide rate in Denmark “has largely been attributed to means restriction, such as efforts to limit availability of firearms and particularly toxic medication,” the authors added.
In those time spans, the adjusted incidence rate ratio for suicide among those with dementia decreased from 2.4 to 1.0, and among those with multiple sclerosis from 2.0 to 1.0. “It is possible that the improvements observed for dementia and multiple sclerosis may be related to improvements in treatment and intensified community-based support,” Dr. Erlangsen and coauthors wrote.
When the researchers used people with rheumatoid arthritis as a reference group, those with a neurologic disorder had a higher suicide rate per 100,000 person-years, 30.2 versus 18.4. The adjusted incidence rate ratio for that comparison was 1.4.
In patients with Huntington’s disease, depression mediated by hyperactivity in the hypothalamic-pituitary-adrenal axis may contribute to the risk of suicide. “Witnessing the course of the disease in one’s parent” also may contribute the risk, the researchers wrote.
The analysis may have missed people with neurologic disorders diagnosed before 1977 if they did not have subsequent contact with a hospital, the investigators noted. In addition, diagnoses given in primary care were not included, suicide deaths may be underrecorded, and “adjusting for preexisting mental disorders could be viewed as overadjusting,” they wrote.
The study was supported by a grant from the Psychiatric Research Foundation in Denmark. The authors reported that they had no disclosures.

The absolute risk difference is small, but statistically significant. “These findings do not necessarily warrant changing the management of treatment for individual patients,” wrote Annette Erlangsen, PhD, a researcher at the Danish Research Institute for Suicide Prevention in Hellerup, and colleagues. “As with all patients, physicians should be aware of the potential for depression, demoralization, and suicide.”
In addition, dementia, Alzheimer’s disease, and intellectual disabilities may be associated with lower suicide rates, according to the study, which was published in JAMA.
“Plausible mechanisms” could underlie the association between neurologic disease and suicide, the authors wrote. A neurologic diagnosis “may constitute a distressing life event,” and the diseases may have psychological, physical, and psychiatric effects. Patients may see themselves as a burden or have less financial security. In addition, the diseases may entail “communication difficulties, poor sleep, and pain.” Neurologic diseases may alter brain circuitry and functioning and influence aggression and impulsivity. “People with neurologic disorders may also have easier access to toxic medication,” they added.
More than a dozen conditions examined
Prior studies have found associations between neurologic conditions and rates of suicide, but data have been inconclusive or inconsistent for some of the disorders. To examine whether people with neurologic disorders have higher suicide rates, relative to people without these disorders, the researchers conducted a retrospective study. They analyzed data from more than 7.3 million people aged 15 years or older who lived in Denmark between 1980 and 2016. The cohort included more than 1.2 million people with neurologic disorders. The investigators identified neurologic disorders using ICD codes for head injury, stroke, epilepsy, polyneuropathy, diseases of the myoneural junction, Parkinson’s disease, multiple sclerosis, CNS infections, meningitis, encephalitis, amyotrophic lateral sclerosis, Huntington’s disease, dementia, intellectual disability, and other brain disorders. They compared incidence rates using a Poisson regression model and adjusted for time period, sex, age, region, socioeconomic status, comorbidity, self-harm or psychiatric hospitalization prior to a neurologic diagnosis, and whether a person lived alone.
In all, 35,483 people in the cohort died by suicide at an average age of about 52 years; 77.4% were male. About 15% of those who died by suicide had a neurologic disorder. The suicide incidence rate among people with a neurologic disorder was 44.0 per 100,000 person-years, whereas the rate among people without a neurologic disorder was 20.1 per 100,000 person-years.
The adjusted incidence rate ratio for people with a neurologic disorder was 1.8. The rate ratio was highest during the 3 months after diagnosis, at 3.1. Huntington’s disease and amyotrophic lateral sclerosis were associated with “the largest excess adjusted [incidence rate ratios] of suicide mortality,” with a rate ratio of 4.9 for each condition, the researchers reported. The adjusted incidence rate ratio was 1.7 for head injury, 1.3 for stroke, 1.7 for epilepsy, 1.4 for intracerebral hemorrhage, 1.3 for cerebral infarction, 1.3 for subarachnoid hemorrhage, 1.7 for polyneuropathy and peripheral neuropathy, 2.2 for Guillain-Barré syndrome, 1.9 for diseases of myoneural junction and muscle, 1.8 for other brain disorders, 1.7 for Parkinson’s disease, 2.2 for multiple sclerosis, and 1.6 for CNS infection.

Physician groups push back on Medicaid block grant plan
It took less than a day for physician groups to start pushing back at the Centers for Medicare & Medicaid Services over its new Medicaid block grant plan, which was introduced on Jan. 30.
Dubbed “Healthy Adult Opportunity,” the agency is offering all states the chance to participate in a block grant program through the 1115 waiver process.
According to a fact sheet issued by the agency, the program will focus on “adults under age 65 who are not eligible for Medicaid on the basis of disability or their need for long term care services and supports, and who are not eligible under a state plan. Other very low-income parents, children, pregnant women, elderly adults, and people eligible on the basis of a disability will not be directly affected – except from the improvement that results from states reinvesting savings into strengthening their overall programs.”
States will be operating within a defined budget when participating in the program and expenditures exceeding that defined budget will not be eligible for additional federal funding. Budgets will be based on a state’s historic costs, as well as national and regional trends, and will be tied to inflation with the potential to have adjustments made for extraordinary events. States can set their baseline using the prior year’s total spending or a per-enrollee spending model.
A Jan. 30 letter to state Medicaid directors notes that states participating in the program “will be granted extensive flexibility to test alternative approaches to implementing their Medicaid programs, including the ability to make many ongoing program adjustments without the need for demonstration or state plan amendments that require prior approval.”
Among the activities states can engage in under this plan are adjusting cost-sharing requirements, adopting a closed formulary, and applying additional conditions of eligibility. Requests, if approved, will be approved for a 5-year initial period, with a renewal option of up to 10 years.
But physician groups are not seeing a benefit with this new block grant program.
“Moving to a block grant system will likely limit the ability of Medicaid patients to receive preventive and needed medical care from their family physicians, and it will only increase the health disparities that exist in these communities, worsen overall health outcomes, and ultimately increase costs,” Gary LeRoy, MD, president of the American Academy of Family Physicians, said in a statement.
The American Medical Association concurred.
“The AMA opposes caps on federal Medicaid funding, such as block grants, because they would increase the number of uninsured and undermine Medicaid’s role as an indispensable safety net,” Patrice Harris, MD, the AMA’s president, said in a statement. “The AMA supports flexibility in Medicaid and encourages CMS to work with states to develop and test new Medicaid models that best meet the needs and priorities of low-income patients. While encouraging flexibility, the AMA is mindful that expanding Medicaid has been a literal lifesaver for low-income patients. We need to find ways to build on this success. We look forward to reviewing the proposal in detail.”
Officials at the American College of Obstetricians and Gynecologists said the changes have the potential to harm women and children’s health, as well as negatively impact physician reimbursement and ultimately access to care.
“Limits on the federal contribution to the Medicaid program would negatively impact patients by forcing states to reduce the number of people who are eligible for Medicaid coverage, eliminate covered services, and increase beneficiary cost-sharing,” ACOG President Ted Anderson, MD, said in a statement. “ACOG is also concerned that this block grant opportunity could lower physician reimbursement for certain services, forcing providers out of the program and jeopardizing patients’ ability to access health care services. Given our nation’s stark rates of maternal mortality and severe maternal morbidity, we are alarmed by the Administration’s willingness to weaken physician payment in Medicaid.”

Staged hemispheric embolization: How to treat hemimegalencephaly within days of birth
BALTIMORE – About one in 4,000 children are born with hemimegalencephaly, meaning one brain hemisphere is abnormally formed and larger than the other.
The abnormal hemisphere causes seizures, and when they become intractable, the standard of care is to remove it as soon as possible; the longer the abnormal hemisphere is left in, the worse children do developmentally, and the less likely hemispherectomy will stop the seizures.
A problem comes up, however, when children become intractable before they’re 3 months old: “Neurosurgeons won’t touch them,” said Taeun Chang, MD, a neonatal neurointensivist at Children’s National Medical Center in Washington.
Newborns’ coagulation systems aren’t fully developed, and the risk of fatal hemorrhage is too high, she explained.
Out of what she said was a sense of “desperation” to address the situation, Dr. Chang has spearheaded a new approach for newborns at Children’s National, serial glue embolization to induce targeted strokes in the affected hemisphere. She reported on the first five cases at the American Epilepsy Society annual meeting.
At this point, “I feel like we’ve pretty much figured out the technique in terms of minimizing the complications. There’s no reason to wait anymore” for surgery as newborns get worse and worse, she said.
The technique
In two or three stages over several days, the major branches of the affected hemisphere’s anterior, middle, and posterior cerebral arteries are embolized. “You have to glue a long area and put in a lot of glue and glue up the secondary branches because [newborns] are so good at forming collaterals,” Dr. Chang said.
Fresh frozen plasma is given before and after each embolization session to boost coagulation proteins. Nicardipine is given during the procedure to prevent vasospasms. The one death in the series, case four, was in an 11-day old girl who vasospasmed, ruptured an artery over the tip of the guidewire, and hemorrhaged.
After the procedure, body temperature is kept at 36° C to prevent fever; sodium is kept high, and ins and outs are matched, to reduce brain edema; and blood pressure is tightly controlled. Children are kept on EEG during embolization and for days afterwards, and seizures, if any, are treated. The next embolization comes after peak swelling has passed in about 48-72 hours.
“The reason we can get away with this without herniation is that newborns’ skulls are soft, and their sutures are open,” so cerebral edema is manageable, Dr. Chang said.
Learning curve and outcomes
“What we learned in the first two cases” – a 23-day-old boy and 49-day-old girl – “was to create effective strokes. That’s not something any of us are taught to do,” she said.
“We were not trying to destroy the whole hemisphere, just the area that was seizing on EEG.” That was a mistake, she said: Adjacent areas began seizing and both children went on to anatomical hemispherectomies and needed shunts.
They are 5 years old now, and both on four seizure medications. The boy is in a wheelchair, fed by a G-tube, and has fewer than 20 words. The girl has a gait trainer, is fed mostly by G-tube, and has more than 50 words.
The third patient had her middle and posterior cerebral arteries embolized beginning when she was 43 days old. She was seizure free when she left the NICU, but eventually had a functional hemispherectomy. She’s 2 years old now, eating by mouth, in a gait trainer, and speaks in one- or two-word sentences. She’s on three seizure medications.
Outcomes have been best for patient five. Her posterior, middle, and anterior cerebral arteries were embolized starting at 14 days. She’s 1 year old now, seizure free on three medications, eating by G-tube and mouth, and has three-five words.
Dr. Chang said that newborns with hemimegalencephaly at Children’s National aren’t lingering as long on failing drug regimens these days. “We go to intervention now that we have this option” after they fail just two or three medications.
Given that the fifth patient, treated at 2 weeks old, is the only one who has been seizure free, she suspects it’s probably best to do embolization sooner rather than later, just as with anatomical hemispherectomy in older children. “We’ve got the sense that even a couple of weeks makes a difference. People need to come to us sooner,” Dr. Chang said.
It’s possible embolization could be a sound alternative to surgery even after 3 months of age. Focal embolization might also be a viable alternative to surgery to knock out epileptogenic lesions in children with tuberous sclerosis. Dr. Chang and her colleagues are interested in those and other possibilities, and plan to continue to develop the approach, she said.
There was no funding, and the investigators didn’t have any relevant disclosures.

Dependent trait in chronic migraine may predict nonresponse to onabotulinumtoxin A
according to research published in the January issue of Headache. The research may be the first to show that personality traits predict response to onabotulinumtoxin A in this population.
“These findings point out that conducting an evaluation of personality traits in patients with chronic migraine might be helpful in the prediction of the course and election of the treatment, as well as identifying patients who might benefit from a multidisciplinary approach,” wrote Alicia Gonzalez-Martinez, MD, of the Hospital Universitario de La Princesa and Instituto de Investigación Sanitaria de La Princesa in Madrid and colleagues. “Categorical questionnaires such as the Salamanca screening test seem to be useful for this purpose.”
Researchers used ICD-10 personality criteria
Personality patterns in patients with migraine and other primary headaches have been the subject of decades of research. Munoz et al. found that certain personality traits are associated with migraine and chronic migraine, and this association may influence clinical management and treatment. The effect of personality traits on response to treatment, however, had not been studied previously.
Dr. Gonzalez-Martinez and colleagues hypothesized that cluster C traits (e.g., obsessive-compulsive, dependent, and anxious), as defined by ICD-10, are associated with nonresponse to onabotulinumtoxin A. To test this hypothesis, they conducted a case-control observational study in a cohort of patients with chronic migraine. Eligible patients presented to one of two headache units of a tertiary hospital between January and May 2018. The investigators obtained a complete headache history and demographic information from each patient. Patients had at least two treatment cycles of onabotulinumtoxin A. Dr. Gonzalez-Martinez and colleagues defined treatment response as a reduction in the number of monthly migraine days of at least 50% after at least two treatment cycles.
The investigators assessed participants’ personality traits by administering the Salamanca test, a brief categorical inventory that examines 11 personality traits using 22 questions. Patients completed the test at the beginning of the study period and before they were classified as responders or nonresponders.
Medication overuse was a potential confounder
The study population included 112 patients with chronic migraine. One hundred patients (89%) were women. Participants’ mean age at initiation of onabotulinumtoxin A treatment was 43 years. The population’s mean duration of chronic migraine was 29 months. Eighty-three patients (74.1%) had medication overuse, and 96 (85.7%) responded to onabotulinumtoxin A.
Cluster A traits in the population included paranoid (prevalence, 10.7%), schizoid (38.4%), and schizotypal (7.1%). Cluster B traits included histrionic (50%), antisocial (1.8%), narcissistic (9.8%), emotional instability subtype impulsive (27.7%), and emotional instability subtype limit (EISL, 24.1%). Cluster C traits were anxious (58.9%) anancastic (i.e., obsessive-compulsive, 54.5%), and dependent (32.1%).
The investigators found no differences in demographics between responders and nonresponders. In a univariate analysis, dependent traits (e.g., passivity and emotional overdependence on others) and EISL traits (e.g., impulsivity and disturbed self-image) were significantly more common among nonresponders. In a multivariate analysis, dependent traits remained significantly associated with nonresponse to onabotulinumtoxin A.
Medication overuse was a potential confounder in the study, according to Dr. Gonzalez-Martinez and colleagues. One of the study’s limitations was its absence of a healthy control group. Another was the fact that the psychometrics of the Salamanca screening test have not been published in a peer-reviewed journal and may need further examination.
Dependent personality “may also be part of the proposed chronic pain sufferer personality,” wrote the investigators. “Early detection of personality traits could improve management and outcome of chronic migraine patients. Additionally, the possibility to predict the effectiveness of onabotulinumtoxin A therapy may reduce costs and latency time of effect in patients with improbable effectiveness.”
The study had no outside funding, and the authors reported no conflicts of interest.
