Elevated levels of high-density lipoprotein (HDL) and apolipoprotein A1 (apoA1) are associated with a reduced risk for amyotrophic lateral sclerosis (ALS), new research shows.

The study also linked a higher ratio of total cholesterol to HDL with an increased risk for ALS. These findings, investigators noted, point to potential future biomarkers in screening for ALS and perhaps an approach to reduce risk or delay onset of ALS in the longer term.

“They may help build a biochemical picture of what’s going on and who might be at risk of developing ALS in the near future, particularly in people with a genetic predisposition to ALS,” study investigator Alexander G. Thompson, DPhil, Medical Research Council clinician scientist, Nuffield Department of Clinical Neurosciences, University of Oxford, United Kingdom, said in an interview.

He emphasized that although the current observational study cannot show cause and effect, such a relationship may exist.

The study was published online September 13 in the Journal of Neurology, Neurosurgery and Psychiatry.
 

Registry data

ALS is a disorder of progressive degeneration of upper and lower motor neurons. Genetic variants account for fewer than 15% of cases. The factors that are associated with the greatest risk are unclear.

To investigate, the researchers used data from the UK Biobank, a prospective cohort study of persons aged 39-72 years. Participants underwent an initial assessment between March 2006 and October 2010 and were followed for a median of 11.9 years.

In addition to providing demographic and health information, participants provided blood samples for biochemical analysis. This included measurements of total cholesterol, HDL, low-density lipoprotein (LDL) cholesterol, triglycerides, apoA1, apolipoprotein B (apoB), A1c, and creatinine.

Researchers used diagnostic codes in inpatient health records and death certificate information to verify ALS diagnoses.

The analysis included data from 502,409 participants. The mean age of the participants was 58 years, and 54.4% were women. During follow-up, 343 participants were diagnosed with ALS, yielding a crude incidence of 5.85 per 100,000 per year (95% confidence interval, 5.25-6.51).

After controlling for sex and age, results showed that higher HDL (hazard ratio, 0.84; 95% CI, 0.73-0.96; P = .010) and higher apoA1 (HR, 0.83; 95% CI, 0.72-0.94, P = .005) were associated with a reduced risk for subsequent ALS.

A higher ratio of total cholesterol to HDL was associated with increased ALS risk.

A rise in neurofilaments and other markers of neuronal loss typically occur within about a year of ALS symptom onset. To ensure that they were capturing participants whose blood samples were taken before the onset of neurodegeneration, the researchers performed a secondary analysis that excluded ALS diagnoses within 5 years of the baseline study visit.

Results of the analysis were largely consistent with models incorporating all participants with regard to magnitude and direction of associations. In addition, the findings persisted in models that controlled for statin use, smoking, and vascular disease.
 

Mechanism unclear

To more closely examine lipid status prior to ALS diagnosis, the researchers performed a nested case-control analysis that involved matching each participant who developed ALS with 20 participants of similar age, sex, and time of enrollment who did not develop the disease.

Linear models showed that levels of LDL and apoB, which are closely correlated, decrease over time in those who developed ALS. This was not the case for HDL and apoA1. “This suggests LDL levels are going down, and we think it’s happening quite some time before symptoms start, even before neurodegeneration starts,” said Dr. Thompson.

How blood lipid levels correlate with ALS risk is unclear. Dr. Thompson noted that LDL is an oxidative stressor and can provoke inflammation, whereas HDL is an antioxidant that is involved in healing. However, given that LDL and HDL don’t cross into the brain in great amounts, “the lipid changes may be a reflection of something else going on that contributes to the risk of ALS,” he said.

More evidence of a causal relationship is needed before any clinical implications can be drawn, including the potential manipulation of lipid levels to prevent ALS, said Dr. Thompson. In addition, even were such a relationship to be established, altering lipid levels in a healthy individual who has no family history of ALS would be unlikely to alter risk.

Dr. Thompson added that among those with a genetic predisposition, lipid changes “may be a marker or clue that something’s going wrong in the nervous system and that ALS might be about to start. That would be the ideal time to treat people at risk of ALS with gene therapy.”
 

Metabolism gone awry

Commenting on the findings, Stephen Goutman, MD, director, Pranger ALS Clinic, associate professor of neurology, Neuromuscular Program, University of Michigan, Ann Arbor, called the study “very interesting.” Of particular note was a trend of decreasing LDL and apoB levels prior to an ALS diagnosis, said Dr. Goutman.

The results are in agreement with several studies that show an alteration in metabolism in individuals with ALS, he said. “These altered metabolic pathways may provide some signal that something has gone awry,” he commented.

He agreed that an “ultimate goal” is to identify factors or biomarkers that can be used to predict whether individuals will develop ALS and to enable intervention to decrease the risk.

This new research highlights the value of population-based registries and large prospective cohorts, said Dr. Goutman. “These help to better define the genetic, environmental, and metabolic factors that increase and predict ALS risk,” he said.

But more work is needed, said Dr. Goutman. He noted that in the study, only 192 participants were diagnosed with ALS more than 5 years after enrollment. “This means additional large cohort studies are needed, especially those that reflect the diversity of the population, for us to solve the mystery of ALS and to prevent it,” he said.

Dr. Thompson and Dr. Goutman have disclosed no relevant financial relationships.

Pfizer’s COVID-19 vaccine could be authorized for ages 5-11 by the end of October, according to Reuters.

The timeline is based on the expectation that Pfizer will have enough data from clinical trials to request Food and Drug Administration emergency use authorization for the age group near the end of September. Then the FDA would likely make a decision about the vaccine’s safety and effectiveness in children within about 3 weeks, two sources told Reuters.

Anthony Fauci, MD, chief medical adviser to President Joe Biden and director of the National Institute of Allergy and Infectious Diseases, spoke about the timeline during an online town hall meeting Friday, Reuters reported. The meeting was attended by thousands of staff members at the National Institutes of Health.

If Pfizer submits paperwork to the FDA by the end of September, the vaccine could be available for kids around mid-October, Dr. Fauci said, and approval for the Moderna vaccine could come in November. Moderna will take about 3 weeks longer to collect and analyze data for ages 5-11.

Pfizer has said it would have enough data for ages 5-11 in September and would submit its documentation for FDA authorization soon after. Moderna told investors on Sept. 9 that data for ages 6-11 would be available by the end of the year.

On Sept. 10, the FDA said it would work to approve COVID-19 vaccines for children quickly once companies submit their data, according to Reuters. The agency said it would consider applications for emergency use, which would allow for faster approval.

Pfizer’s vaccine is the only one to receive full FDA approval, but only for people ages 16 and older. Adolescents ages 12-15 can receive the Pfizer vaccine under the FDA’s emergency use authorization.

For emergency use authorization, companies must submit 2 months of safety data versus 6 months for full approval. The FDA said on Sept. 10 that children in clinical trials should be monitored for at least 2 months to observe side effects.

BioNTech, Pfizer’s vaccine manufacturing partner, told a news outlet in Germany that it plans to request authorization globally for ages 5-11 in coming weeks, according to Reuters.

“Already over the next few weeks, we will file the results of our trial in 5- to 11-year-olds with regulators across the world and will request approval of the vaccine in this age group, also here in Europe,” Oezlem Tuereci, MD, the chief medical officer for BioNTech, told Der Spiegel.

The company is completing the final production steps to make the vaccine at lower doses for the younger age group, she said. Pfizer and BioNTech will also seek vaccine approval for ages 6 months to 2 years later this year.

“Things are looking good, everything is going according to plan,” Ugur Sahin, MD, the CEO of BioNTech, told Der Spiegel.

Telehealth can be effective for delivering cognitive-behavioral therapy for insomnia (CBT-I) – and is not inferior to in-person treatment, new research suggests.

Results from a study of 60 adults with insomnia disorder showed no significant between-group difference at 3-month follow-up between those assigned to receive in-person CBT-I and those assigned to telehealth CBT-I in regard to change in score on the Insomnia Severity Index (ISI).

In addition, both groups showed significant change compared with a wait-list group, indicating that telehealth was not inferior to the in-person mode of delivery, the investigators note.

Telehealth ‘explosion’

Although CBT-I is the recommended intervention for insomnia, “widespread implementation of CBT-I is limited by the lack of clinicians who are trained in this treatment,” the investigators note. There is a “need for strategies to increase access, particularly for patients in areas with few health care providers.”

Telehealth is a promising technology for providing treatment, without the necessity of having the patient and the practitioner in the same place. There has been an “explosion” in its use because of restrictions necessitated by the COVID-19 pandemic. However, the “rapid deployment of telehealth interventions did not allow time to assess this approach in a controlled manner,” so it is possible that this type of communication might reduce treatment efficacy, the investigators note.

Previous research suggests that telehealth psychotherapeutic treatments in general are not inferior to in-person treatments. One study showed that CBT-I delivered via telehealth was noninferior to in-person delivery. However, that study did not include a control group.

“I have been doing telehealth clinical work for about 10 years – so way before the pandemic pushed everything virtual,” Dr. Gehrman said. “But when I would talk about my telehealth work to other providers, I would frequently get asked whether the advantages of telehealth (greater access to care, reduced travel costs) came at a price of lower efficacy.”

Dr. Gehrman said he suspected that telehealth treatment was just as effective and wanted to formally test this impression to see whether he was correct.

The investigators randomly assigned 60 adults (mean age, 32.72 years; mean ISI score, 17.0; 65% women) with insomnia disorder to in-person CBT-I (n = 20), telehealth-delivered CBT-I (n = 21), or to a wait-list control group (n = 19). For the study, insomnia disorder was determined on the basis of DSM-5 criteria.

Most participants had completed college or postgraduate school (43% and 37%, respectively) and did not have many comorbidities.

The primary outcome was change on the ISI. Other assessments included measures of depression, anxiety, work and social adjustment, fatigue, and medical outcomes. Participants also completed a home unattended sleep study using a portable monitor to screen participants for obstructive sleep apnea.

Both types of CBT-I were delivered over 6 to 8 weekly sessions, with 2-week and 3-month post-treatment follow-ups.

An a priori margin of -3.0 points was used in the noninferiority analysis, and all analyses were conducted using mixed-effects models, the authors explain.
 

Necessary evil?

In the primary noninferiority analyses, the mean change in ISI score from baseline to 3-month follow-up was -7.8 points for in-person CBT-I, -7.5 points for telehealth, and -1.6 for wait list.

The difference between the CBT-I groups was not statistically significant (t 28 = -0.98, P = .33).

“The lower confidence limit of this between-group difference in the mean ISI changes was greater than the a priori margin of -3.0 points, indicating that telehealth treatment was not inferior to in-person treatment,” the investigators write.

Although there were significant improvements on most secondary outcome measures related to mood/anxiety and daytime functioning, the investigators found no group differences.

The findings suggest that the benefits of telehealth, including increased access and reduced travel time, “do not come with a cost of reduced efficacy,” the researchers write.

The study was conducted prior to the COVID-19 pandemic, the investigators note. However, the results “underscore that the use of telehealth during the pandemic is not a ‘necessary evil,’ but rather a means of providing high quality care while reducing risks of exposure,” they write.
 

Benefits, fidelity maintained

Commenting on the study, J. Todd Arnedt, PhD, professor of psychiatry and neurology and co-director of the Sleep and Circadian Research Laboratory, Michigan Medicine, University of Michigan, Ann Arbor, said it is “one of the first studies to clearly demonstrate that the benefits and fidelity of CBT for insomnia, which is most commonly delivered in-person, can be maintained with telehealth delivery.”

Dr. Arnedt is also director of the Behavioral Sleep Medicine Program and was not involved in the study. He said the findings “support the use of this modality by providers to expand access to this highly effective but underutilized insomnia treatment.”

Additionally, telehealth delivery of CBT-I “offers a safe and effective alternative to in-person care for improving insomnia and associated daytime consequences and has the potential to reduce health care disparities by increasing availability to underserved communities,” Dr. Arnedt said.

However, the investigators point out that the utility of this approach for underserved communities needs further investigation. A study limitation was that the participants were “generally healthy and well educated.”

In addition, further research is needed to see whether the findings can be generalized to individuals who have “more complicated health or socioeconomic difficulties,” they write.

The study was funded by a grant from the American Sleep Medicine Foundation and the Doris Duke Charitable Foundation Clinical Scientist Development Award. Dr. Gehrman has received research funding from Merck, is a consultant to WW, and serves on the scientific advisory board of Eight Sleep. The other authors’ disclosures are listed in the original article. Dr. Arnedt reports no relevant financial relationships but notes that he was the principal investigator of a similar study run in parallel to this one that was also funded by the American Academy of Sleep Medicine Foundation at the same time.

The primary outcome was change on the ISI. Other assessments included measures of depression, anxiety, work and social adjustment, fatigue, and medical outcomes. Participants also completed a home unattended sleep study using a portable monitor to screen participants for obstructive sleep apnea.

Both types of CBT-I were delivered over 6 to 8 weekly sessions, with 2-week and 3-month post-treatment follow-ups.

An a priori margin of -3.0 points was used in the noninferiority analysis, and all analyses were conducted using mixed-effects models, the authors explain.
 

Necessary evil?

In the primary noninferiority analyses, the mean change in ISI score from baseline to 3-month follow-up was -7.8 points for in-person CBT-I, -7.5 points for telehealth, and -1.6 for wait list.

The difference between the CBT-I groups was not statistically significant (t 28 = -0.98, P = .33).

“The lower confidence limit of this between-group difference in the mean ISI changes was greater than the a priori margin of -3.0 points, indicating that telehealth treatment was not inferior to in-person treatment,” the investigators write.

Although there were significant improvements on most secondary outcome measures related to mood/anxiety and daytime functioning, the investigators found no group differences.

The findings suggest that the benefits of telehealth, including increased access and reduced travel time, “do not come with a cost of reduced efficacy,” the researchers write.

The study was conducted prior to the COVID-19 pandemic, the investigators note. However, the results “underscore that the use of telehealth during the pandemic is not a ‘necessary evil,’ but rather a means of providing high quality care while reducing risks of exposure,” they write.
 

Benefits, fidelity maintained

Commenting on the study, J. Todd Arnedt, PhD, professor of psychiatry and neurology and co-director of the Sleep and Circadian Research Laboratory, Michigan Medicine, University of Michigan, Ann Arbor, said it is “one of the first studies to clearly demonstrate that the benefits and fidelity of CBT for insomnia, which is most commonly delivered in-person, can be maintained with telehealth delivery.”

Dr. Arnedt is also director of the Behavioral Sleep Medicine Program and was not involved in the study. He said the findings “support the use of this modality by providers to expand access to this highly effective but underutilized insomnia treatment.”

Additionally, telehealth delivery of CBT-I “offers a safe and effective alternative to in-person care for improving insomnia and associated daytime consequences and has the potential to reduce health care disparities by increasing availability to underserved communities,” Dr. Arnedt said.

However, the investigators point out that the utility of this approach for underserved communities needs further investigation. A study limitation was that the participants were “generally healthy and well educated.”

In addition, further research is needed to see whether the findings can be generalized to individuals who have “more complicated health or socioeconomic difficulties,” they write.

The study was funded by a grant from the American Sleep Medicine Foundation and the Doris Duke Charitable Foundation Clinical Scientist Development Award. Dr. Gehrman has received research funding from Merck, is a consultant to WW, and serves on the scientific advisory board of Eight Sleep. The other authors’ disclosures are listed in the original article.

Telehealth can be effective for delivering cognitive-behavioral therapy for insomnia (CBT-I) – and is not inferior to in-person treatment, new research suggests.

Results from a study of 60 adults with insomnia disorder showed no significant between-group difference at 3-month follow-up between those assigned to receive in-person CBT-I and those assigned to telehealth CBT-I in regard to change in score on the Insomnia Severity Index (ISI).

In addition, both groups showed significant change compared with a wait-list group, indicating that telehealth was not inferior to the in-person mode of delivery, the investigators note.

Telehealth ‘explosion’

Although CBT-I is the recommended intervention for insomnia, “widespread implementation of CBT-I is limited by the lack of clinicians who are trained in this treatment,” the investigators note. There is a “need for strategies to increase access, particularly for patients in areas with few health care providers.”

Telehealth is a promising technology for providing treatment, without the necessity of having the patient and the practitioner in the same place. There has been an “explosion” in its use because of restrictions necessitated by the COVID-19 pandemic. However, the “rapid deployment of telehealth interventions did not allow time to assess this approach in a controlled manner,” so it is possible that this type of communication might reduce treatment efficacy, the investigators note.

Previous research suggests that telehealth psychotherapeutic treatments in general are not inferior to in-person treatments. One study showed that CBT-I delivered via telehealth was noninferior to in-person delivery. However, that study did not include a control group.

“I have been doing telehealth clinical work for about 10 years – so way before the pandemic pushed everything virtual,” Dr. Gehrman said. “But when I would talk about my telehealth work to other providers, I would frequently get asked whether the advantages of telehealth (greater access to care, reduced travel costs) came at a price of lower efficacy.”

Dr. Gehrman said he suspected that telehealth treatment was just as effective and wanted to formally test this impression to see whether he was correct.

The investigators randomly assigned 60 adults (mean age, 32.72 years; mean ISI score, 17.0; 65% women) with insomnia disorder to in-person CBT-I (n = 20), telehealth-delivered CBT-I (n = 21), or to a wait-list control group (n = 19). For the study, insomnia disorder was determined on the basis of DSM-5 criteria.

Most participants had completed college or postgraduate school (43% and 37%, respectively) and did not have many comorbidities.

The primary outcome was change on the ISI. Other assessments included measures of depression, anxiety, work and social adjustment, fatigue, and medical outcomes. Participants also completed a home unattended sleep study using a portable monitor to screen participants for obstructive sleep apnea.

Unlike in adults, seizures, including status epilepticus (SE), may be the first and main manifestation of COVID-19 in children, new research suggests.

Seizures may occur even in children with no history of epilepsy and in the absence of fever or severe COVID-19 illness, necessitating a “high index” of suspicion for the virus to make an early diagnosis and allow for appropriate infection control measures, say the researchers.

“We hope to increase physicians’ awareness of noninfluenza-like presentations of COVID in children. In areas with a high prevalence of COVID, we suggest that children with seizures be tested for COVID,” Tal Gilboa, MD, director of the child neurology unit and codirector of epilepsy, Hadassah Medical Center, Jerusalem, told this news organization.

The study was published online August 27 in the journal Seizure.
 

Presenting symptom

Among 175 children diagnosed with acute SARS-CoV-2 infection in the emergency department over 10 months in 2020, 11 (6%) presented with seizures. Studies in adults with COVID-19 have reported seizures in 0% to 2% of cases, the investigators note.

The 11 children with seizures (seven boys) ranged in age from 6 months to 17 years (median age, 11.5 years). All of them had seizures as the presenting sign of infection and none had severe COVID-19 requiring ventilatory or hemodynamic support. Six of the 11 children presented with fever.

Seven of the children had a prior history of neurological disorder: Five had epilepsy, one had a single unprovoked seizure 3 years before admission, and one had an intellectual disability. Three of the children had uncontrolled seizures despite appropriate treatment with antiseizure medication.

Nine of the 11 children presented with generalized tonic-clonic seizures. One child with a prior history of uncontrolled epilepsy with multiple seizure types had a focal tonic seizure. The youngest patient, a 5-month-old infant, presented with bilateral asymmetrical tonic-clonic seizure.

Of note, say the investigators, five of the 11 children presented with convulsive SE; none had a history of prior SE, and one had no history of seizures.

Although young age, especially under 12 months, is a known risk factor for SE, four of the five patients with SE were between 5 and 17 years old. All five children with SE responded to treatment with antiseizure medications.

All 11 children made a full recovery while in hospital, although further follow-up is essential to determine long-term outcomes, the researchers report.

“Children with no prior history of epilepsy and those with well-controlled epilepsy who present with breakthrough seizures, regardless of their body temperature, should be considered as potentially infected by SARS-CoV-2,” said Dr. Gilboa.

“It is possible, however unlikely, that a child, especially with prior epilepsy, may have an unprovoked seizure while being asymptomatically infected by SARS-CoV-2; in any case, infection control measures should be taken,” Dr. Gilboa added.
 

Need for replication

Weighing in on the study, Carl E. Stafstrom, MD, PhD, professor of neurology and pediatrics, Johns Hopkins University, Baltimore, said it’s important to note that “about half of the children had had epilepsy already, and for whatever reason, had a seizure, which required an ED visit, and then they found COVID.”

“Nevertheless, this article is interesting and surprising in what they found because nobody else has found nearly as frequent a seizure presentation,” said Dr. Stafstrom, director of the John M. Freeman Pediatric Epilepsy Center, Johns Hopkins Medicine.

“We would want to see some replication from other institutions and other populations,” he added.

The study had no specific funding. Dr. Gilboa and Dr. Stafstrom have reported no relevant financial relationships.

Cannabis-based medicinal products (CBMPs) have shown early promise for refractory childhood epilepsy, but positive media attention, as well as pressure from politicians and marijuana advocacy groups, should not supplant clinical trials and acceptable standards of evidence, according to two leading experts.

In a recent invited review article, Martin Kirkpatrick, MD, of the University of Dundee (Scotland), and Finbar O’Callaghan, MD, PhD, of University College London suggested that childhood epilepsy may be easy terrain for commercial interests to break ground, and from there, build their presence.

“Children with epilepsy are at risk of being used as the ‘Trojan horse’ for the cannabis industry,” Dr. Kirkpatrick and Dr. O’Callaghan wrote in Developmental Medicine & Child Neurology.

They noted that some of the first publicized success stories involving cannabis oil for epilepsy coincided with the rise of the medicinal and recreational cannabis markets, which will constitute an estimated 55-billion-dollar industry by 2027.

“Pediatric neurologists, imbued with the need to practice evidence-based medicine and wary of prescribing unlicensed medicines that had inadequate safety data, suddenly found themselves at odds with an array of vested interests and, most unfortunately, with the families of patients who were keen to try anything that would alleviate the effects of their child’s seizures,” the investigators wrote.

According to the review, fundamental questions about cannabis remain unanswered, including concerns about safety with long-term use, and the medicinal value of various plant components, such as myrcene, a terpene that gives cannabis its characteristic smell.

“A widely discussed issue is whether the terpenes add any therapeutic benefit, contributing to the so-called entourage effect of ‘whole-plant’ medicines,” the investigators wrote. “The concept is that all the constituents of the plant together create ‘the sum of all the parts that leads to the magic or power of cannabis.’ Although commonly referred to, there is little or no robust evidence to support the entourage effect as a credible clinical concept.”

Clinical evidence for treatment of pediatric epilepsy is also lacking, according to Dr. Kirkpatrick and Dr. O’Callaghan.

“Unfortunately, apart from the studies of pure cannabidiol (CBD) in Lennox–Gastaut and Dravet syndromes and tuberous sclerosis complex, level I evidence in the field of CBMPs and refractory epilepsy is lacking,” they wrote.

While other experts have pointed out that lower-level evidence – such as patient-reported outcomes and observational data – have previously been sufficient for drug licensing, Dr. Kirkpatrick and Dr. O’Callaghan noted that such exceptions “almost always” involve conditions without any effective treatments, or drugs that are undeniably effective.

“This is not the scenario with CBMPs,” they wrote, referring to current clinical data as “low-level” evidence “suggesting … possible efficacy.”

They highlighted concerns about placebo effect with open-label epilepsy studies, citing a randomized controlled trial for Dravet syndrome, in which 27% of patients given placebo had a 50% reduction in seizure frequency.

“We need carefully designed, good-quality CBMP studies that produce results on which we can rely,” Dr. Kirkpatrick and Dr. O’Callaghan concluded. “We can then work with families to choose the best treatments for children and young people with epilepsy. We owe this to them.”
 

A therapy of last resort

Jerzy P. Szaflarski, MD, PhD, of the University of Alabama at Birmingham, agreed that data are lacking for the use of CBMPs with patients who have epilepsy and other neurologic conditions; however, he also suggested that Dr. Kirkpatrick and Dr. O’Callaghan did not provide adequate real-world clinical context.

“Medical cannabis is not used as a first-, second-, or third-line therapy,” Dr. Szaflarski said. “It’s mostly used as a last resort in the sense that patients have already failed multiple other therapies.” In that respect, patients and parents are desperate to try anything that might work. “We have medical cannabis, and our patients want to try it, and at the point when multiple therapies have failed, it’s a reasonable option.”

While Dr. Szaflarski agreed that more high-quality clinical trials are needed, he also noted the practical challenges involved in such trials, largely because of variations in cannabis plants.

“The content of the cannabis plant changes depending on the day that it’s collected and the exposure to sun and how much water it has and what’s in the soil and many other things,” Dr. Szaflarski said. “It’s hard to get a very good, standardized product, and that’s why there needs to be a good-quality product delivered by the industry, which I have not seen thus far.”

For this reason, Dr. Szaflarski steers parents and patients away from over-the-counter CBMPs and toward Epidiolex, the only FDA-approved form of CBD.

“There is evidence that Epidiolex works,” he said. “I don’t know whether the products that are sold in a local cannabis store have the same high purity as Epidiolex. I tell [parents] that we should try Epidiolex first because it’s the one that is approved. But if it doesn’t work, we can go in that [other] direction.”

For those going the commercial route, Dr. Szaflarski advised close attention to product ingredients, to ensure that CBMPs are “devoid of any impurities, pesticides, fungicides, and other products that could be potentially dangerous.”

Parents considering CBMPs for their children also need to weigh concerns about long-term neurological safety, he added, noting that, on one hand, commercial products lack data, while on the other, epilepsy itself may cause harm.

“They need to consider the potential effects [of CBMPs] on their child’s brain and development versus … the effects of seizures on the brain,” Dr. Szaflarski said.

Dr. Kirkpatrick and Dr. O’Callaghan disclosed an application for a National Institute for Health Research–funded randomized controlled trial on CBMPs and joint authorship of British Paediatric Neurology Association Guidance on the use of CBMPs in children and young people with epilepsy. Dr. Szaflarski disclosed a relationship with Greenwich Biosciences and several other cannabis companies.

They highlighted concerns about placebo effect with open-label epilepsy studies, citing a randomized controlled trial for Dravet syndrome, in which 27% of patients given placebo had a 50% reduction in seizure frequency.

“We need carefully designed, good-quality CBMP studies that produce results on which we can rely,” Dr. Kirkpatrick and Dr. O’Callaghan concluded. “We can then work with families to choose the best treatments for children and young people with epilepsy. We owe this to them.”
 

A therapy of last resort

Jerzy P. Szaflarski, MD, PhD, of the University of Alabama at Birmingham, agreed that data are lacking for the use of CBMPs with patients who have epilepsy and other neurologic conditions; however, he also suggested that Dr. Kirkpatrick and Dr. O’Callaghan did not provide adequate real-world clinical context.

“Medical cannabis is not used as a first-, second-, or third-line therapy,” Dr. Szaflarski said. “It’s mostly used as a last resort in the sense that patients have already failed multiple other therapies.” In that respect, patients and parents are desperate to try anything that might work. “We have medical cannabis, and our patients want to try it, and at the point when multiple therapies have failed, it’s a reasonable option.”

While Dr. Szaflarski agreed that more high-quality clinical trials are needed, he also noted the practical challenges involved in such trials, largely because of variations in cannabis plants.

“The content of the cannabis plant changes depending on the day that it’s collected and the exposure to sun and how much water it has and what’s in the soil and many other things,” Dr. Szaflarski said. “It’s hard to get a very good, standardized product, and that’s why there needs to be a good-quality product delivered by the industry, which I have not seen thus far.”

For this reason, Dr. Szaflarski steers parents and patients away from over-the-counter CBMPs and toward Epidiolex, the only FDA-approved form of CBD.

“There is evidence that Epidiolex works,” he said. “I don’t know whether the products that are sold in a local cannabis store have the same high purity as Epidiolex. I tell [parents] that we should try Epidiolex first because it’s the one that is approved. But if it doesn’t work, we can go in that [other] direction.”

For those going the commercial route, Dr. Szaflarski advised close attention to product ingredients, to ensure that CBMPs are “devoid of any impurities, pesticides, fungicides, and other products that could be potentially dangerous.”

Parents considering CBMPs for their children also need to weigh concerns about long-term neurological safety, he added, noting that, on one hand, commercial products lack data, while on the other, epilepsy itself may cause harm.

“They need to consider the potential effects [of CBMPs] on their child’s brain and development versus … the effects of seizures on the brain,” Dr. Szaflarski said.

Dr. Kirkpatrick and Dr. O’Callaghan disclosed an application for a National Institute for Health Research–funded randomized controlled trial on CBMPs and joint authorship of British Paediatric Neurology Association Guidance on the use of CBMPs in children and young people with epilepsy. Dr. Szaflarski disclosed a relationship with Greenwich Biosciences and several other cannabis companies.

Steal from the warm, give to the cold

If there’s one constant in life other than taxes, it’s elderly people moving to Florida. The Sunshine State’s reputation as a giant retirement home needs no elaboration, but why do senior citizens gravitate there? Well, many reasons, but a big one is that, the older you get, the more susceptible and sensitive you are to the cold. And now, according to a new study, we may have identified a culprit.

Researchers from Yale University examined a group of mice and found that the older ones lacked ICL2 cells in their fatty tissue. These cells, at least in younger mice, help restore body heat when exposed to cold temperatures. Lacking these cells meant that older mice had a limited ability to burn their fat and raise their temperature in response to cold.

Well, job done, all we need to do now is stimulate production of ICL2 cells in elderly people, and they’ll be able to go outside in 80-degree weather without a sweater again. Except there’s a problem. In a cruel twist of fate, when the elderly mice were given a molecule to boost ICL2 cell production, they actually became less tolerant of the cold than at baseline. Oops.

The scientists didn’t give up though, and gave their elderly mice ICL2 cells from young mice. This finally did the trick, though we have to admit, if that treatment does eventually scale up to humans, the prospect of a bunch of senior citizens taking ICL2 cells from young people to stay warm does sound a bit like a bad vampire movie premise. “I vant to suck your immune cell group 2 innate lymphoid cells!” Not the most pithy catch phrase in the world.
 

Grocery store tapping your subconscious? It’s a good thing

We all know there’s marketing and functionality elements to grocery stores and how they’re set up for your shopping pleasure. But what if I told you that the good old supermarket subconscious trick works on how healthy food decisions are?

PxHere

In a recent study, researchers at the University of Southampton in England found that if you placed a wider selection of fruits and vegetables near the entrances and more nonfood items near checkouts, sales decreased on the sweets and increased on the produce. “The findings of our study suggest that a healthier store layout could lead to nearly 10,000 extra portions of fruit and vegetables and approximately 1,500 fewer portions of confectionery being sold on a weekly basis in each store,” lead author Dr. Christina Vogel explained.

You’re probably thinking that food placement studies aren’t new. That’s true, but this one went above and beyond. Instead of just looking at the influence placement has on purchase, this one took it further by trying to reduce the consumers’ “calorie opportunities” and examining the effect on sales. Also, customer loyalty, patterns, and diets were taken into account across multiple household members.

The researchers think shifting the layouts in grocery stores could shift people’s food choices, producing a domino effect on the population’s overall diet. With obesity, diabetes, and cardiology concerns always looming, swaying consumers toward healthier food choices makes for better public health overall.

So if you feel like you’re being subconsciously assaulted by veggies every time you walk into Trader Joe’s, just know it’s for your own good.
 

TikTokers take on tics

We know TikTok is what makes a lot of teens and young adults tick, but what if TikTokers are actually catching tic disorders from other TikTokers?

Bicanski/Pixnio

TikTok blew up during the pandemic. Many people were stuck at home and had nothing better to do than make and watch TikTok videos. The pandemic brought isolation, uncertainty, and anxiety. The stress that followed may have caused many people, mostly women and young girls, to develop tic disorders.

There’s a TikTok for everything, whether it’s a new dance or a recipe. Many people even use TikTok to speak out about their illnesses. Several TikTokers have Tourette’s syndrome and show their tics on their videos. It appears that some audience members actually “catch” the tics from watching the videos and are then unable to stop certain jerking movements or saying specific words.

Neurologists at the University of Calgary (Alta.), who were hearing from colleagues and getting referrals of such patients, called it “an epidemic within the pandemic.” The behavior is not actually Tourette’s, they told Vice, but the patients “cannot stop, and we have absolutely witnessed that.”

There is, of course, controversy over the issue. One individual with the condition said, “I feel like there’s a lot of really weird, backwards stigma on TikTok about tic disorders. Like, you aren’t allowed to have one unless it’s this one.”

Who would have guessed that people would disagree over stuff on the Internet?
 

Look on the bright side: Obesity edition

The pandemic may have postponed “Top Gun: Maverick” and “The Marvelous Mrs. Maisel” until who-knows-when, but we here at LOTME are happy to announce the nearly-as-anticipated return of Bacteria vs. the World.

As you may recall from our last edition of BVTW, bacteria battled the ghost of Charles Darwin, who had taken the earthly form of antibiotics capable of stopping bacterial evolution. Tonight, our prokaryotic protagonists take on an equally relentless and ubiquitous challenger: obesity.

Specifically, we’re putting bacteria up against the obesity survival paradox, that phenomenon in which obesity and overweight seem to protect against – yes, you guessed it – bacterial infections.

A Swedish research team observed a group of 2,196 individual adults who received care for suspected severe bacterial infection at Skaraborg Hospital in Skövde. One year after hospitalization, 26% of normal-weight (body mass index, 18.5-24.99) patients were dead, compared with 17% of overweight (BMI, 25.0-29.99), 16% of obese (BMI, 30.0-34.99), and 9% of very obese (BMI >35) patients.

These results confirm the obesity survival paradox, but “what we don’t know is how being overweight can benefit the patient with a bacterial infection, or whether it’s connected with functions in the immune system and how they’re regulated,” lead author Dr. Åsa Alsiö said in a written statement.

A spokes-cell for the bacteria disputed the results and challenged the legitimacy of the investigators. When asked if there should be some sort of reexamination of the findings, he/she/it replied: “You bet your flagella.” We then pointed out that humans don’t have flagellum, and the representative raised his/her/its flagella in what could only be considered an obscene gesture.

My first hospital consult was also on my first day of practice, in July, 1998.

I was in a small room, subleased from an oncology group. My schedule, as first day schedules are, was sparse.

Around noon one of the oncology docs asked me to come to his exam room, so I went across the hall. There he had a lady in her late 50s, with known metastatic cancer. He’d brought her in for a few days of worsening headaches and diplopia, and my 10-second neurological exam showed dysconjugate gaze and dysarthria. He said he was admitting her to the hospital, and asked if I’d consult on her.

I hung out in the hospital’s MRI control room later that day, waiting for her images to come up. I was nervous, maybe even a little scared. In spite of having survived medical school, residency, and fellowship, I was worried I’d screwed up the case, somehow. If the MRI was normal, I’d look like an idiot. My career would be over, on day one. No one would ever consult me again.

Of course, the MRI showed a brainstem metastasis (in addition to other places), and my initial differential was correct. Good for me, terrible for the patient. I ordered Decadron, called the oncologist, spoke to the patient and her family, and went home. I followed her for maybe a another few days, mainly because I didn’t know what the protocol was for signing off.

Self-doubt is common in all fields, especially when starting out, but probably strongest in medicine. A lot depends on us getting the right answer – quickly – in cases like that one. In my case this was compounded by its being my first day of practice. There was no attending I could call for help. I was working without a net.

But the years of training paid off, I got the case right, and moved on. Twenty-three years later it seems silly that I was so worried. Nowadays I order the MRI, move to the next patient, and try not to think about it until the results come back or a nurse calls with a status change. If my initial impression is wrong, I move down the differential list.

But questioning ourselves, then or now, is still critical. It helps us think of other possibilities, avoid mistakes, and do what’s right for our patients.

It’s what makes us better doctors.

After making an insulting comment to a surgery scheduler, a surgeon become the subject of a peer review investigation.

The surgeon had been called in on a Saturday morning for surgery, but when he arrived at the hospital, staff informed him that the operating room had been incorrectly booked and asked him to come back that afternoon. When the surgeon returned, the room still wasn’t ready, recounted David Beran, DO, a peer reviewer and medical director for the emergency department at University Medical Center New Orleans, in Louisiana. After more waiting and staff uncertainty about which operating room was going to open, the surgeon became frustrated and said to the scheduler: “Any idiot could figure this out!”

During his peer review, the surgeon acknowledged that he shouldn’t have made the rude remark to the scheduler, Dr. Beran said. His exasperation stemmed from an ongoing problem – operating rooms at the hospital were being inefficiently managed.

“The surgeon acknowledged that even though there was a systems issue at the root, that’s not justification to speak to people unprofessionally,” Dr. Beran said. “So, there was education for the surgeon, but the surgeon was also able to explain the frustration that led to that point.”

System problems are commonly encountered by peer reviewers, said Dr. Beran.

“There’s a huge gap between administration and clinical professionals when it comes to peer review,” he said. “So many times, bad situations, whether they’re clinical or behavioral, often boil down to systems issues or some inadequacy, whether it’s an EMR [electronic medical record] problem, an inefficacy, or how complicated a process is for an end user. But having a peer review situation that then leads to a system-level change that prevents that problem from happening again is really unlikely. There’s a huge disconnect between those two.”

Peer review is generally a process that goes on behind closed doors. Although structures may differ, peer review is generally described as the process by which physicians assess the quality of their peers’ work to ensure that standards of care are being met. The process is often used to evaluate issues regarding clinical care as well as behavioral complaints against physicians.

Doctors who undergo peer review frequently share their experiences, but reviewers themselves rarely speak out. For this story, this news organization spoke with several current and former peer reviewers about what really goes on during peer reviews, what frustrates them, and what they’ve learned along the way.

“Peer review processes are in place to build stronger institutions and stronger practices, and they’re supposed to be helpful,” Dr. Beran said. “But because of how opaque they are, it immediately puts physicians on the defensive, and it doesn’t always succeed in what it’s trying to do. I think that’s one of the biggest challenges.”
 

Biased reviewers taint evaluations

A peer reviewer on and off throughout her career, Indiana family physician Lana Patch, MD, said she always strived to be fair when evaluating fellow physicians. But not every reviewer she encountered operated the same way, she said. Some were biased.

In one case, Dr. Patch peer reviewed a general surgeon who had performed a hysterectomy on a 16-year-old girl. The surgeon believed the teenager likely had an acute appendicitis, but it turned out she had a uterine pathology, Dr. Patch said. The surgeon saved the girl’s life, but the case came under review because of the patient’s age and the fact that her uterus was removed. A local obstetrician-gynecologist weighed in on the case.

“The local ob.gyn. saw it as a turf battle,” recalled Dr. Patch, who is now retired after 30 years of practice in eastern Indiana. “The doctor had nothing but bad to say about the surgeon. He was a competitor.”

Because it was a small hospital, the committee sometimes had trouble finding a specialist who was qualified to give an opinion and who wasn’t in competition with the physician in question, said Dr. Patch. Eventually they found an outside pediatric gynecologist who reviewed the case and concluded that the surgeon had followed the standard of care.

Personal agendas in can come from different directions, said Robert Marder, MD, the author of several books on peer review. Dr. Marder is a consultant who assists with peer review redesign. He has worked with hundreds of medical staff leaders and is a former vice president at the Greeley Company, a consulting firm in Danvers, Mass., that performs peer review redesign. Dr. Marder is president of Robert J. Marder Consulting.

“It goes both ways,” Dr. Marder said. “I’ve seen where somebody with a personal view decides to bring things to the peer review committee specifically because they want the peer review committee to have an adverse view of this person and get them off the medical staff. And I’ve seen hospitals that are uncomfortable with a certain person for whatever reason and want the peer review committee to address it, as opposed to addressing it from a human resource standpoint.”

Dr. Patch recalled a case in which reviewers and hospital leaders were at odds over the credentialing of a physician. Fifteen years earlier, while driving in California, the psychiatrist had been pulled over and was found with an ounce of marijuana, she said.

“We wanted to privilege him,” Dr. Patch said. “As staff physicians, we felt that was 15 years ago, people change over time. Doctors are human beings, too. He seemed to have good credentials and good training. The hospital said, ‘Oh no, we can’t have somebody like this.’ “

The psychiatrist was placed on probation and had to undergo a review every 90 days for about 3 years. Eventually, he was privileged, Dr. Patch said.

Bias among reviewers, including unintentional bias, is also a challenge, Dr. Marder noted. Some initial reviewers score a physician too harshly, he said, whereas others underscore.

“Underscoring is more insidious and more difficult to deal with,” Dr. Marder said. “Underscoring is where the reviewer is too nice. They tend to dismiss things from their colleagues rather than recognize them as an opportunity to help them improve. With underscoring, a lot of committees, if the initial reviewer says the care was appropriate, they don’t even look at the case. They just take that one person’s word for it.”
 

Reviewers: Looks can be deceiving

When first examining the documented details of a case, it can be easy for peer reviewers to make a quick judgment about what happened, Dr. Beran said.

“You get these complaints, and you read through it, and you think, ‘Oh man, this person really messed up,’ “ he said. “Then you hear the doctor’s side of it, and you realize, ‘No, there’s a much bigger picture at play.’ You realize both sides have valid perspectives on it.”

In one case, for example, Dr. Beran recalled a complaint against a physician who made a snarky remark to a nurse. The doctor had asked the nurse for a piece of equipment, and the nurse said she was busy preparing the room for a patient. The doctor made a comment along the lines of, “Well, would you like me to do that for you and also intubate the patient while you do some charting?!”

At first glance, it appeared that the physician lashed out inappropriately at the nurse. But when reviewers heard from the doctor, they learned that the nurses knew that a trauma patient was coming by ambulance and that he would likely require a ventilator, Dr. Beran said. As the minutes ticked by, however, the nurses were seen in the break room chatting. Nothing had been prepared in the room, including any airway supply.

“The patient had a prolonged course and a very difficult intubation and could have very easily wound up with a much worse outcome for something the nurses had been warned about prior to the patient’s arrival,” he said. “I can see anybody getting upset in that situation if I warned them 5 or 10 minutes beforehand, ‘Get this stuff ready,’ and then nothing was done.”

There was no direct penalty for the physician.

Just as some complaints can be misleading, the clinical record in some peer review cases can also lead reviewers astray.

Physicians frequently include too much irrelevant information in the record, which can cloud a peer review, said Hans Duvefelt, MD, a family physician at Pines Health Services, in Van Buren, Maine. Dr. Duvefelt is a former medical director at Bucksport Regional Health Center, in Ellsworth, Maine. Both facilities are federally qualified health centers where continuous, random peer reviews are required.

In one case, Dr. Duvefelt was peer reviewing a physician’s office note regarding an elderly patient with a low-grade fever. The final diagnosis was urinary tract infection. Dr. Duvefelt said he had trouble following the doctor’s line of thinking because of a plethora of unnecessary data in the 10-page document. The office note included past medical history, prior lab and imaging test results, and an extensive narrative section that included a mixture of active medical problems and ongoing relationships with specialists, he said.

After reading through the printout three times, Dr. Duvefelt said he finally found mention of increased urinary dribbling and details about an enlarged prostate. He also spotted a same-day urinalysis among nearly a dozen other previous lab tests that had no connection to body temperature. Dr. Duvefelt gave the physician a passing grade but also left a scathing note about all the irrelevant information.

“It’s very common,” Dr. Duvefelt said. “It’s a disaster. Other doctors can’t follow your thinking. A reviewer has a hard time determining whether the doctor acted reasonably.”
 

Slackers make bad reviewers

Although dedicated reviewers work hard to get to the bottom of cases, it’s not uncommon for some committee members to hardly work at all, according to experts.

Dr. Marder said he’s seen many instances in which reviewers were assigned a review but did not complete it for months. Most committees have set time frames in which reviewers must complete their review.

“That delays that review, and by that time, the review is older and it’s harder to remember things,” he said. “It’s not fair to the physician. If there was a problem the physician could fix and you don’t tell him for 3 or 4 months what it is, he may do the same thing again. The case might come before the committee again and it looks like he’s repeated something, but you never gave him the opportunity to improve.”

Other reviewers fail to attend meetings regularly. Peer review committee members are generally volunteers, and meetings are usually held in the early mornings or late evenings.

“There are reasons for not attending occasionally, but some people put on a committee just don’t take it seriously,” Dr. Marder said. “They don’t fulfill their responsibilities as well as they should. If you accept the job, do the job.”

For physicians considering becoming a peer reviewer, Dr. Beran offers these tips: Be transparent, help physicians understand next steps, and make yourself as available as allowed to answer questions.

Know your committee’s policies and procedures, and follow them, added Dr. Marder. It’s also a good idea to work with your hospital’s quality staff, he said.

Reviewers should keep in mind that they may not always be the one assessing someone else, Dr. Beran said.

“Realize very easily you could be on the other side of that table for things that are outside your control,” he said. “How would you want to be treated?”

After making an insulting comment to a surgery scheduler, a surgeon become the subject of a peer review investigation.

The surgeon had been called in on a Saturday morning for surgery, but when he arrived at the hospital, staff informed him that the operating room had been incorrectly booked and asked him to come back that afternoon. When the surgeon returned, the room still wasn’t ready, recounted David Beran, DO, a peer reviewer and medical director for the emergency department at University Medical Center New Orleans, in Louisiana. After more waiting and staff uncertainty about which operating room was going to open, the surgeon became frustrated and said to the scheduler: “Any idiot could figure this out!”

During his peer review, the surgeon acknowledged that he shouldn’t have made the rude remark to the scheduler, Dr. Beran said. His exasperation stemmed from an ongoing problem – operating rooms at the hospital were being inefficiently managed.

“The surgeon acknowledged that even though there was a systems issue at the root, that’s not justification to speak to people unprofessionally,” Dr. Beran said. “So, there was education for the surgeon, but the surgeon was also able to explain the frustration that led to that point.”

System problems are commonly encountered by peer reviewers, said Dr. Beran.

“There’s a huge gap between administration and clinical professionals when it comes to peer review,” he said. “So many times, bad situations, whether they’re clinical or behavioral, often boil down to systems issues or some inadequacy, whether it’s an EMR [electronic medical record] problem, an inefficacy, or how complicated a process is for an end user. But having a peer review situation that then leads to a system-level change that prevents that problem from happening again is really unlikely. There’s a huge disconnect between those two.”

Peer review is generally a process that goes on behind closed doors. Although structures may differ, peer review is generally described as the process by which physicians assess the quality of their peers’ work to ensure that standards of care are being met. The process is often used to evaluate issues regarding clinical care as well as behavioral complaints against physicians.

Doctors who undergo peer review frequently share their experiences, but reviewers themselves rarely speak out. For this story, this news organization spoke with several current and former peer reviewers about what really goes on during peer reviews, what frustrates them, and what they’ve learned along the way.

“Peer review processes are in place to build stronger institutions and stronger practices, and they’re supposed to be helpful,” Dr. Beran said. “But because of how opaque they are, it immediately puts physicians on the defensive, and it doesn’t always succeed in what it’s trying to do. I think that’s one of the biggest challenges.”
 

Biased reviewers taint evaluations

A peer reviewer on and off throughout her career, Indiana family physician Lana Patch, MD, said she always strived to be fair when evaluating fellow physicians. But not every reviewer she encountered operated the same way, she said. Some were biased.

In one case, Dr. Patch peer reviewed a general surgeon who had performed a hysterectomy on a 16-year-old girl. The surgeon believed the teenager likely had an acute appendicitis, but it turned out she had a uterine pathology, Dr. Patch said. The surgeon saved the girl’s life, but the case came under review because of the patient’s age and the fact that her uterus was removed. A local obstetrician-gynecologist weighed in on the case.

“The local ob.gyn. saw it as a turf battle,” recalled Dr. Patch, who is now retired after 30 years of practice in eastern Indiana. “The doctor had nothing but bad to say about the surgeon. He was a competitor.”

Because it was a small hospital, the committee sometimes had trouble finding a specialist who was qualified to give an opinion and who wasn’t in competition with the physician in question, said Dr. Patch. Eventually they found an outside pediatric gynecologist who reviewed the case and concluded that the surgeon had followed the standard of care.

Personal agendas in can come from different directions, said Robert Marder, MD, the author of several books on peer review. Dr. Marder is a consultant who assists with peer review redesign. He has worked with hundreds of medical staff leaders and is a former vice president at the Greeley Company, a consulting firm in Danvers, Mass., that performs peer review redesign. Dr. Marder is president of Robert J. Marder Consulting.

“It goes both ways,” Dr. Marder said. “I’ve seen where somebody with a personal view decides to bring things to the peer review committee specifically because they want the peer review committee to have an adverse view of this person and get them off the medical staff. And I’ve seen hospitals that are uncomfortable with a certain person for whatever reason and want the peer review committee to address it, as opposed to addressing it from a human resource standpoint.”

Not so long ago, Heather Simpson of Dallas was known as the anti-vaccine mom who dressed as “the measles” for Halloween. She painted red spots on her face and posted her photo on Facebook, joking: “Was trying to think of the least scary thing I could be for Halloween … so I became the measles.” It went viral with the anti-vaccine crowd.

But between that Halloween and today, a series of “aha” moments transformed Ms. Simpson’s attitudes toward vaccines.

In January 2021, one of those moments involved her daughter, now 4, who was scratched by a feral cat, raising concerns about tetanus. Her daughter had been bitten by a dog when she was just 1, and Ms. Simpson turned down advice then to get a tetanus shot. “I was convinced the tetanus shot would kill her faster than the tetanus.”

After the cat incident, the anxiety was so exhausting, she listened to the nurse practitioner at the clinic, whom she trusted. The nurse gently reassured Ms. Simpson that the shot was less risky than the possibility of tetanus – but did not bombard her with statistics – and that won over Ms. Simpson and triggered an overall rethinking of her vaccine stance.

Fast-forward to February, and that “aha” turned into action when Ms. Simpson launched a “Back to the Vax” effort with a fellow former vaccine opponent. Through their website, Facebook page, and podcasts, they now encourage people to get the COVID-19 vaccine, as well as other immunizations.
 

Challenge: Reaching the rest

With just over 52% of those eligible in the United States fully vaccinated as of Sept. 1, health care providers and others have a continuing challenge ahead: Trying to convince those who are eligible but still holding out to get vaccinated.

Recent data and a poll show some movement in the right direction, as immunizations are increasing and hesitancy is declining among certain groups. According to federal officials, about 14 million people in the United States got their first dose in August, an increase of 4 million, compared to the numbers who got it in July.

And a new poll from the Axios-IPSOS Coronavirus Index found only one in five Americans, or 20%, say they are not likely to get the vaccine, while “hard opposition,” those not at all likely, has dropped to 14% of those adults.

But there is still a lot of work to do. So, how do medical professionals or concerned citizens reach those who haven’t gotten vaccinated yet, whatever their reason?

Many experts in communication and persuasion that this news organization talked to agree that throwing statistics at people hesitant to get the COVID-19 vaccine is generally useless and often backfires.

So what does work, according to these experts?

• Emphasizing the trends of more people getting vaccinated.
• Focusing on everyone’s freedom of choice.
• Listening to concerns without judgment.
• Offering credible information.
• Correcting myths when necessary.
• Helping them fit vaccination into their “world view.”

Stories over statistics

Talking about the trends of vaccinations can definitely change minds about getting vaccinated, said Robert Cialdini, PhD, regents professor emeritus of psychology and marketing at Arizona State University, Tempe, and author of the recently updated book, “Influence: The Psychology of Persuasion,” which has sold over 5 million copies since it was first published in 1984.

Face-to-face with a hesitant patient, a doctor can say: “More and more people are being vaccinated every day,” Dr. Cialdini says. “The reason you say more and more is [that] it conveys a trend. When people see a trend, they project it into the future that it is going to get even larger.”

A focus on choice can also help people change their minds and accept the vaccine, he says. “A lot of conspiracy theorists claim they don’t want to do it because they are being pushed or forced by the government, and they are resisting that.”

If that’s the case, presenting people with new information, such as the increased infectiousness of the Delta variant, and suggesting that a decision be made based on the new information, can work, Dr. Cialdini says, but be sure to end with: “It’s completely up to you.”

“This removes all their sense of being pushed. It says, ‘Here is all the evidence.’ ” At this point, a doctor’s personal recommendation with a patient who trusts him or her may sway them, Dr. Cialdini said. “I think you have to personalize the communication in both directions. That is, to say, ‘For someone in your situation, I would personally recommend that you get the vaccine.’ ” A health care professional’s authority and expertise can carry the day, he says, although “not always.”

This approach worked, Dr. Cialdini says, with a friend of the family hesitant about the COVID-19 vaccine. “I told him: ‘We have gotten it. You trust us, right?’ ” He waited for the person to say yes.

Then: “For someone in your position, my personal recommendation is to get vaccinated. There is new information about the vaccine, and more and more people are getting vaccinated. And of course, it is completely up to you.”

The person decided to get the vaccine.
 

‘Live in that space’

“People develop negative attitudes [about vaccines] by accessing alternative sources of information, anecdotes, and personal stories,” said Matthew Seeger, PhD, dean of the College of Fine, Performing, and Communication Arts and codirector of the Center for Emerging Infectious Diseases at Wayne State University in Detroit.

“If we are going to change their opinion, we need to live in that space.” That means listening first, he says. Ask: “Where did you get that information? How credible do you think the sources are? What do you mean about the vaccine changing DNA?”

Then, you might respond, he said, by addressing that specific information, such as, “We have no cases of DNA being changed.”

Dr. Seeger recalls that his mother would simply talk louder when she couldn’t understand someone who wasn’t a native English speaker. “That’s what we are trying to do with the vaccine-hesitant,” he says. “In some cases, we are yelling at them.” Instead, he says, probe their sources of information.

For some who are vaccine-hesitant, Dr. Seeger said, it is not just about the vaccine. The attitude about vaccines is tied in, often, with a distrust of government and feelings about personal freedom. “That’s one reason it’s so hard to change the attitude.” For some, getting the vaccine in a family against the vaccine might also disrupt their social structure or even get them ostracized.

For these people, a health care provider might give opportunities to get the vaccine without affecting either what they see as their political stance or upsetting family harmony. “There are places you can go, make an appointment, get a vaccine, and nobody knows,” Dr. Seeger said.

One Missouri doctor told CNN that some people calling for a vaccine appointment do request privacy, such as going through a drive-thru or having the shot as they sit in their cars. She said the hospital tries to accommodate them, reasoning that every additional vaccine shot is a win.

Dr. Seeger agrees. “Of course there are still public records,” he says, “but you can still claim you are a vaccine denier. It’s very difficult to persuade people to give up their whole world. Vaccine denial is part of that world. At this point, we need to do whatever we can to get people vaccinated.”
 

From peer to peer

A theme that runs through many of these persuasion techniques is peer pressure.

One example, while a bit more profane and confrontational than some groups, is COVIDAteMyFace, a subgroup, or “subreddit,” of the popular online site Reddit, which hosts numerous forums inviting users to share news and comments on a variety of topics. The subreddit has over 20,000 members. Its purpose, says the sub’s creator, “was to document the folks who denied COVID, then got bitten in the ass by it.” Reports are of actual cases.

“It’s interesting and powerful that Reddit users are taking this on,” Dr. Seeger said. And this kind of peer pressure, or peer-to-peer information, can be persuasive, he says. “We often seek consensual validation from peers about risk messages and risk behaviors.”

For instance, hurricane evacuation notices are more effective, he said, when people learn their neighbors are leaving.

Peer information – “the number of others who are doing or believing or responding to something – definitely persuades people,” agreed Dr. Cialdini. “When a lot of others are responding in a particular way – for example, getting vaccinated – people follow for three reasons: The action seems more appropriate or correct, it appears more feasible to perform, and it avoids social disapproval from those others.”
 

Let them talk, give them time

Gladys Jimenez is a contact tracer and “vaccine ambassador” for Tracing Health, a partnership between the Oregon Public Health Institute and the Public Health Institute that has nearly 300 bilingual contract tracers who serve the ethnic communities they’re from. During a typical week, she talks to 50 people or more, and promoting the vaccine is top of mind.

The conversations, Ms. Jimenez said, are like a dance. She presents information, then steps back and lets them talk. “I want to hear the person talk, where they are coming from, where they are at.” Depending on what they say, she gives them more information or corrects their misinformation. “They often will say, ‘Oh, I didn’t know that.’ ”

It’s rarely one conversation that convinces hesitant people, she said. “I’m planting this seed in their brain. ... people want someone to listen to them ... they want to vent.”

Once you let them do that, Ms. Jimenez said, “I can tell the person is in a different state of mind.” She also knows that people “will make the decision in their own time.”

With time, people can change their minds, as a Southern California woman who resisted at first (and asked to remain anonymous) can attest. “When the vaccine first came out, I remember thinking [that] it was a quick fix to a very big problem,” she said. The lack of full FDA approval, which has since been granted, was also an issue. She doesn’t oppose vaccines, she said, but was leery just of the COVID-19 vaccine.

When her longtime partner got his vaccine, he urged her to go right away for hers. She stalled. He got his second dose and grew impatient with her hesitancy. It began to wear on the relationship. Finally, the woman talked to two health care professionals she knew socially. They both follow the science, and “they both could explain vaccination to me in a way that resonated. The information was coming from sources I already trusted.”

Those conversations are what convinced her to get vaccinated this summer.
 

Simpson’s transformation

Ms. Simpson of Back to the Vax got her first COVID-19 immunization April 16. She had an allergic reaction, including severe itchiness and a bad headache, and needed emergency care, she said. Even so, she scheduled her second shot appointment.

Like many who turned against vaccines as adults, Ms. Simpson had all her childhood vaccines, but she developed a distrust after watching a lengthy documentary series that warned of vaccine dangers as an adult.

Looking back at that documentary, she thought about how it seems to blame everything – childhood cancer, ADHD, autism, allergies – on vaccinations. That suddenly seemed like sketchy science to her.

So did the claim from a family friend who said she knew someone who got the flu shot and began walking backward. She researched on her own, and with time, she decided to be pro-vaccines.

These days, she continues to find that stories, not statistics, are changing the minds of many who decide to get vaccinated. If the nurse practitioner urging the tetanus shot for her daughter had told her that the tetanus shot is linked with problems in one of a specific number of people who get it, no matter how large that second number was, Ms. Simpson said she would have thought: “What if she is that one?”

So she relies on stories that point out how universally vulnerable people are to COVID-19 first, facts next.

“Facts help once you are already moved,” Ms. Simpson said.

Not so long ago, Heather Simpson of Dallas was known as the anti-vaccine mom who dressed as “the measles” for Halloween. She painted red spots on her face and posted her photo on Facebook, joking: “Was trying to think of the least scary thing I could be for Halloween … so I became the measles.” It went viral with the anti-vaccine crowd.

But between that Halloween and today, a series of “aha” moments transformed Ms. Simpson’s attitudes toward vaccines.

In January 2021, one of those moments involved her daughter, now 4, who was scratched by a feral cat, raising concerns about tetanus. Her daughter had been bitten by a dog when she was just 1, and Ms. Simpson turned down advice then to get a tetanus shot. “I was convinced the tetanus shot would kill her faster than the tetanus.”

After the cat incident, the anxiety was so exhausting, she listened to the nurse practitioner at the clinic, whom she trusted. The nurse gently reassured Ms. Simpson that the shot was less risky than the possibility of tetanus – but did not bombard her with statistics – and that won over Ms. Simpson and triggered an overall rethinking of her vaccine stance.

Fast-forward to February, and that “aha” turned into action when Ms. Simpson launched a “Back to the Vax” effort with a fellow former vaccine opponent. Through their website, Facebook page, and podcasts, they now encourage people to get the COVID-19 vaccine, as well as other immunizations.
 

Challenge: Reaching the rest

With just over 52% of those eligible in the United States fully vaccinated as of Sept. 1, health care providers and others have a continuing challenge ahead: Trying to convince those who are eligible but still holding out to get vaccinated.

Recent data and a poll show some movement in the right direction, as immunizations are increasing and hesitancy is declining among certain groups. According to federal officials, about 14 million people in the United States got their first dose in August, an increase of 4 million, compared to the numbers who got it in July.

And a new poll from the Axios-IPSOS Coronavirus Index found only one in five Americans, or 20%, say they are not likely to get the vaccine, while “hard opposition,” those not at all likely, has dropped to 14% of those adults.

But there is still a lot of work to do. So, how do medical professionals or concerned citizens reach those who haven’t gotten vaccinated yet, whatever their reason?

Many experts in communication and persuasion that this news organization talked to agree that throwing statistics at people hesitant to get the COVID-19 vaccine is generally useless and often backfires.

So what does work, according to these experts?

• Emphasizing the trends of more people getting vaccinated.
• Focusing on everyone’s freedom of choice.
• Listening to concerns without judgment.
• Offering credible information.
• Correcting myths when necessary.
• Helping them fit vaccination into their “world view.”

Stories over statistics

Talking about the trends of vaccinations can definitely change minds about getting vaccinated, said Robert Cialdini, PhD, regents professor emeritus of psychology and marketing at Arizona State University, Tempe, and author of the recently updated book, “Influence: The Psychology of Persuasion,” which has sold over 5 million copies since it was first published in 1984.

Face-to-face with a hesitant patient, a doctor can say: “More and more people are being vaccinated every day,” Dr. Cialdini says. “The reason you say more and more is [that] it conveys a trend. When people see a trend, they project it into the future that it is going to get even larger.”

A focus on choice can also help people change their minds and accept the vaccine, he says. “A lot of conspiracy theorists claim they don’t want to do it because they are being pushed or forced by the government, and they are resisting that.”

If that’s the case, presenting people with new information, such as the increased infectiousness of the Delta variant, and suggesting that a decision be made based on the new information, can work, Dr. Cialdini says, but be sure to end with: “It’s completely up to you.”

“This removes all their sense of being pushed. It says, ‘Here is all the evidence.’ ” At this point, a doctor’s personal recommendation with a patient who trusts him or her may sway them, Dr. Cialdini said. “I think you have to personalize the communication in both directions. That is, to say, ‘For someone in your situation, I would personally recommend that you get the vaccine.’ ” A health care professional’s authority and expertise can carry the day, he says, although “not always.”

This approach worked, Dr. Cialdini says, with a friend of the family hesitant about the COVID-19 vaccine. “I told him: ‘We have gotten it. You trust us, right?’ ” He waited for the person to say yes.

Then: “For someone in your position, my personal recommendation is to get vaccinated. There is new information about the vaccine, and more and more people are getting vaccinated. And of course, it is completely up to you.”

The person decided to get the vaccine.
 

‘Live in that space’

“People develop negative attitudes [about vaccines] by accessing alternative sources of information, anecdotes, and personal stories,” said Matthew Seeger, PhD, dean of the College of Fine, Performing, and Communication Arts and codirector of the Center for Emerging Infectious Diseases at Wayne State University in Detroit.

“If we are going to change their opinion, we need to live in that space.” That means listening first, he says. Ask: “Where did you get that information? How credible do you think the sources are? What do you mean about the vaccine changing DNA?”

Then, you might respond, he said, by addressing that specific information, such as, “We have no cases of DNA being changed.”

Dr. Seeger recalls that his mother would simply talk louder when she couldn’t understand someone who wasn’t a native English speaker. “That’s what we are trying to do with the vaccine-hesitant,” he says. “In some cases, we are yelling at them.” Instead, he says, probe their sources of information.

For some who are vaccine-hesitant, Dr. Seeger said, it is not just about the vaccine. The attitude about vaccines is tied in, often, with a distrust of government and feelings about personal freedom. “That’s one reason it’s so hard to change the attitude.” For some, getting the vaccine in a family against the vaccine might also disrupt their social structure or even get them ostracized.

Compared with placebo, tranexamic acid did not reduce hematoma growth in patients with intracerebral hemorrhage (ICH), a new study shows.

In the randomized controlled trial, the rate of hematoma expansion was 40.4% among patients who received tranexamic acid and 41.5% among those who received placebo. The degree of disability at 90 days also did not differ between treatment arms.

“Our work has once again shown that tranexamic acid is safe in spontaneous ICH,” said Jingyi Liu, MD, a physician in the neurocritical care unit at Beijing Tiantan Hospital, Capital Medical University, Beijing. “Larger studies with more specified population are needed to further assess safety and efficacy of tranexamic acid in patients with ICH.”

The findings of the TRAIGE study were presented at the virtual European Stroke Organization Conference (ESOC) 2021. They were also published online June 28 in Stroke and Vascular Neurology.
 

Imaging-based patient selection

ICH is often fatal and entails a high risk for disability, the researchers wrote. Approximately 40% of patients with ICH die within a month of onset, and about two-thirds of patients do not achieve long-term functional independence.

Intracerebral hematoma expansion is predictive of poor clinical outcome in ICH. Data indicate that tranexamic acid, an antifibrinolytic agent, reduces hematoma expansion. But evidence of a clinical benefit of tranexamic acid has been elusive, they noted.

This lack of observed benefit may result from the inappropriate selection of research participants. The emergence of imaging biomarkers may help address this potential problem. In recent years, the blend sign and the black hole sign on noncontrast CT, as well as the spot sign on CT angiography, have been associated with higher risk for hematoma expansion and worse clinical outcome, the researchers wrote.

Between January 2015 and March 2020, the investigators enrolled consecutive patients with acute primary spontaneous ICH into their prospective study. Eligible patients presented at any of 10 stroke centers in China. They had the spot sign, blend sign, or black hole sign at admission and were able to receive treatment within 8 hours of onset.

The investigators randomly assigned patients in equal groups to receive placebo (0.9% NaCl) or tranexamic acid. Patients and study investigators were blinded to treatment assignment. Treatment was administered as an intravenous infusion over 8 hours.

The study’s primary endpoint was intracerebral hematoma expansion by 24 hours after start of treatment. Expansion was defined as an increase of > 6 mL or a growth of > 33% from baseline. Secondary endpoints included poor clinical outcome, defined as a Modified Rankin Scale (mRS) score of 4-6, and all-cause mortality, both at 90 days.
 

No differences in disability

The investigators enrolled 171 patients in their study; 24-hour CT images were available for 169 of them. Follow-up data at 90 days were available for 164 patients. The mean age of the patients was 55.9 years, and 72.5% of participants were men. At baseline, the mean ICH volume was 23.7 mL, and the median hematoma volume was 19.8 mL.

All patients received treatment within 8 hours. Hematoma expansion occurred in 40.9% of patients overall; 34.9% had a poor clinical outcome.

The investigators found no significant difference between treatment arms in the rate of hematoma expansion. This outcome occurred in 40.4% of the tranexamic acid group and 41.5% of the placebo group (odds ratio, 0.96; P = .89).

In addition, the researchers found no significant difference in the distribution of mRS scores at day 90 (P = .70). The rate of all-cause mortality at 90 days was lower in the tranexamic acid group (8.1%) than in the control group (10.0%), but this difference was not statistically significant (P = .71).
 

Potential clotting risk

One reason for the lack of observed benefit with tranexamic acid may be an inappropriate sample size, said Dr. Liu. Patient recruitment was difficult, especially in centers that used the spot sign as an inclusion criterion.

“We think a positive result could be seen in a substantially larger sample size,” said Dr. Liu. “Furthermore, we infer from our subgroup analysis that a more specified patient selection and shorter treatment window may be required for better effect.”

In some of their subgroup analyses, the researchers found a trend toward an increased effect in patients with moderate-size hematoma who received treatment in an earlier window. “That could be the targeted population for future studies,” said Dr. Liu. “We are working on further analysis of the population and possibly international collaboration.”

But tranexamic acid also entails risks, said Louis R. Caplan, MD, professor of neurology at Harvard Medical School, Boston, who provided independent commentary on the findings. “Tranexamic acid works on the thrombolytic system, so it increases clotting, and it does have a risk in people who are older and have risk factors for coronary disease and pulmonary embolism.”

As in ischemic stroke, time to treatment is a crucial consideration. Patients with ICH may receive treatment within 5 or 6 hours of onset, but most hemorrhages have reached their maximum size at that point. “The number of people that you can actually help by reducing the size is small,” said Dr. Caplan. “And then reducing the size in most hemorrhages doesn’t make any clinical difference.”

Stereotactic drainage, in which fluid is physically removed, is more likely to lead to long-term improvement for some patients with hemorrhage than limiting expansion, said Dr. Caplan. “That seems to be a more promising therapy,” he added.

The study was supported by the National Key R&D program of China, the National Natural Science Foundation of China, and the Beijing Science and Technology Commission. Dr. Liu and Dr. Caplan have disclosed no relevant financial relationshps.

Compared with placebo, tranexamic acid did not reduce hematoma growth in patients with intracerebral hemorrhage (ICH), a new study shows.

In the randomized controlled trial, the rate of hematoma expansion was 40.4% among patients who received tranexamic acid and 41.5% among those who received placebo. The degree of disability at 90 days also did not differ between treatment arms.

“Our work has once again shown that tranexamic acid is safe in spontaneous ICH,” said Jingyi Liu, MD, a physician in the neurocritical care unit at Beijing Tiantan Hospital, Capital Medical University, Beijing. “Larger studies with more specified population are needed to further assess safety and efficacy of tranexamic acid in patients with ICH.”

The findings of the TRAIGE study were presented at the virtual European Stroke Organization Conference (ESOC) 2021. They were also published online June 28 in Stroke and Vascular Neurology.
 

Imaging-based patient selection

ICH is often fatal and entails a high risk for disability, the researchers wrote. Approximately 40% of patients with ICH die within a month of onset, and about two-thirds of patients do not achieve long-term functional independence.

Intracerebral hematoma expansion is predictive of poor clinical outcome in ICH. Data indicate that tranexamic acid, an antifibrinolytic agent, reduces hematoma expansion. But evidence of a clinical benefit of tranexamic acid has been elusive, they noted.

This lack of observed benefit may result from the inappropriate selection of research participants. The emergence of imaging biomarkers may help address this potential problem. In recent years, the blend sign and the black hole sign on noncontrast CT, as well as the spot sign on CT angiography, have been associated with higher risk for hematoma expansion and worse clinical outcome, the researchers wrote.

Between January 2015 and March 2020, the investigators enrolled consecutive patients with acute primary spontaneous ICH into their prospective study. Eligible patients presented at any of 10 stroke centers in China. They had the spot sign, blend sign, or black hole sign at admission and were able to receive treatment within 8 hours of onset.

The investigators randomly assigned patients in equal groups to receive placebo (0.9% NaCl) or tranexamic acid. Patients and study investigators were blinded to treatment assignment. Treatment was administered as an intravenous infusion over 8 hours.

The study’s primary endpoint was intracerebral hematoma expansion by 24 hours after start of treatment. Expansion was defined as an increase of > 6 mL or a growth of > 33% from baseline. Secondary endpoints included poor clinical outcome, defined as a Modified Rankin Scale (mRS) score of 4-6, and all-cause mortality, both at 90 days.
 

No differences in disability

The investigators enrolled 171 patients in their study; 24-hour CT images were available for 169 of them. Follow-up data at 90 days were available for 164 patients. The mean age of the patients was 55.9 years, and 72.5% of participants were men. At baseline, the mean ICH volume was 23.7 mL, and the median hematoma volume was 19.8 mL.

All patients received treatment within 8 hours. Hematoma expansion occurred in 40.9% of patients overall; 34.9% had a poor clinical outcome.

The investigators found no significant difference between treatment arms in the rate of hematoma expansion. This outcome occurred in 40.4% of the tranexamic acid group and 41.5% of the placebo group (odds ratio, 0.96; P = .89).

In addition, the researchers found no significant difference in the distribution of mRS scores at day 90 (P = .70). The rate of all-cause mortality at 90 days was lower in the tranexamic acid group (8.1%) than in the control group (10.0%), but this difference was not statistically significant (P = .71).
 

Potential clotting risk

One reason for the lack of observed benefit with tranexamic acid may be an inappropriate sample size, said Dr. Liu. Patient recruitment was difficult, especially in centers that used the spot sign as an inclusion criterion.

“We think a positive result could be seen in a substantially larger sample size,” said Dr. Liu. “Furthermore, we infer from our subgroup analysis that a more specified patient selection and shorter treatment window may be required for better effect.”

In some of their subgroup analyses, the researchers found a trend toward an increased effect in patients with moderate-size hematoma who received treatment in an earlier window. “That could be the targeted population for future studies,” said Dr. Liu. “We are working on further analysis of the population and possibly international collaboration.”

But tranexamic acid also entails risks, said Louis R. Caplan, MD, professor of neurology at Harvard Medical School, Boston, who provided independent commentary on the findings. “Tranexamic acid works on the thrombolytic system, so it increases clotting, and it does have a risk in people who are older and have risk factors for coronary disease and pulmonary embolism.”

As in ischemic stroke, time to treatment is a crucial consideration. Patients with ICH may receive treatment within 5 or 6 hours of onset, but most hemorrhages have reached their maximum size at that point. “The number of people that you can actually help by reducing the size is small,” said Dr. Caplan. “And then reducing the size in most hemorrhages doesn’t make any clinical difference.”
