Strangulation deaths spur FDA alert on pediatric enteral feeding kits
Enteral feeding kits pose a risk for strangulation in children, according to a safety alert from the U.S. Food and Drug Administration. The safety alert was prompted by two deaths linked to the medical devices.
The alert cites the deaths in 2021 of two toddlers who were strangled by tubes in the feeding sets that had become wrapped around their necks.
Clinicians should discuss the risk of strangulation with colleagues and caregivers and encourage them to take steps to keep tubing away from children as much as possible, the agency advised in a Feb. 8, 2022, safety communication.
“When caring for pediatric patients who receive enteral feeding and as part of an individual risk assessment, be aware of the risk of strangulation from the feeding set tubing and follow protocols to monitor medical line safety,” the FDA warned.
Parents should be aware of the risk and avoid leaving tubing where infants or children can become entangled, to the extent that is possible. They also should tell their child’s health care provider if their child has ever been tangled in the tubing and discuss precautions to ensure that tubing does not get wrapped around the neck, as well as any related concerns.
Enteral feeding sets provide nutrition to people who are unable meet their nutritional needs by eating or swallowing. Tubing delivers nutrition formulas, using gravity or a pump, directly to the stomach or small intestine through the nose, mouth, or an opening in the abdomen.
The two reported deaths involved children under the age of 2 years who were found with tubing wrapped around their necks after brief periods when their caregivers were not directly monitoring them. One report described the unsupervised period as about 10 minutes.
“While the FDA believes that death or serious injury from strangulation with enteral feeding set tubing in children is rare, health care providers and caregivers should be aware that these events can and do occur,” according to the alert. “It is also possible that some cases have not been reported to the FDA.”
Parents and health care providers can report injuries caused by these devices to the FDA.

Dupilumab under FDA review for atopic dermatitis in children aged 6 months to 5 years
The and Sanofi.
If approved, dupilumab would be the first biologic approved for children in this age group in the United States, according to the statement. The proposed indication is as add-on therapy for children with moderate to severe AD not adequately controlled with topical prescription therapies or for whom topical therapies are not advised. The FDA granted breakthrough therapy designation for dupilumab for the treatment of severe AD in children aged 6 months to 11 years in 2016.
Approximately 85%-95% of atopic dermatitis patients develop symptoms before 5 years of age, and these symptoms often continue into adulthood, with an increased risk of skin infections and a significant impact on quality of life, according to the statement.
The sBLA is based on data from a phase 3 pivotal study of 162 children aged 6 months to 5 years in which dupilumab was added to standard-of-care topical corticosteroids, presented in December 2021. In the study, dupilumab plus standard of care significantly improved skin clearance and reduced overall disease severity and itch at 16 weeks compared with standard of care alone. Overall, 28% of the children randomized to dupilumab achieved the primary endpoint of clear or almost-clear skin, compared with 4% with those on standard of care alone (P < .0001), according to the manufacturers. Patients in the dupilumab group received either 200 mg (for children weighing ≥ 5 to < 15 kg) or 300 mg (for children weighing ≥ 15 to < 30 kg) every 4 weeks. Safety results were similar to those seen with dupilumab for children aged 6 years and older.
Conjunctivitis and herpes infections were among the most common adverse events associated with dupilumab in the study, according to the statement.
The target action date for the FDA decision on this application is June 9, 2022.

E-cigarettes don’t help smokers quit, suggests new research
From 2013 to 2017, e-cigarette sales in the United States nearly doubled, driven by a rapid uptake of use by adolescents, wrote Riufeng Chen, MD, of the University of California, San Diego, and colleagues, in their paper published in Tobacco Control. However, the subsequent effect of increased e-cigarette use on smoking cessation have not been examined, they said.
In their study, Dr. Chen and colleagues analyzed data from 3,578 previous-year smokers with a recent quit attempt and 1,323 recent former smokers who were part of the PATH cohort in 2017. The participants reported using e-cigarettes or other products to quit cigarette smoking. The primary outcomes were at least 12 months of cigarette abstinence, and tobacco abstinence in 2019. In 2017, 32.8% of established smokers reported trying to quit. Of these, 12.6% used e-cigarettes to help them quit. Cigarette abstinence for at least 12 months for these individuals was 9.9%, which was lower than for those who used either nicotine replacement therapy or a pharmaceutical aid only (15.2%), and about half of the 18.6% abstinence in those who used no products to help them quit.
“In our study, e-cigarettes resulted in seven fewer successful quitters than those who used pharmaceutical aids,” emphasized corresponding author, John P. Pierce, PhD, of the University of California, San Diego.
Among smokers attempting to quit, the adjusted risk difference for cigarette abstinence for a least 12 months with e-cigarettes vs. pharmaceutical aids was –7.3%, and –7.7% for e-cigarettes vs. other smoking cessation methods.
*“Among recent former smokers who had switched to daily use of e-cigarettes in 2017, 43.2% had successfully quit cigarette smoking by 2019, which was similar to those who used e-cigarettes on a nondaily basis (34.6%) or to those who switched to another tobacco product, whether daily (43.6%) or nondaily (44.7%),” the researchers wrote.
The rapid growth in e-cigarette use between 2014 and 2017 has been attributed in part to aggressive marketing of high-nicotine e-cigarettes, they said. “The high-nicotine JUUL e-cigarette has been noted as the closest match to cigarettes in both nicotine delivery and user satisfaction, which should make it one of the best candidates as a product to which smokers could switch in order to maintain their nicotine habit,” they said in their discussion of the findings.
More research needed
The researchers acknowledged the need to review more recent data.
“When we looked ahead to 2019, recent former smokers had started using high-nicotine e-cigarettes. The effectiveness of high-nicotine e-cigarettes at preventing relapse will require another follow-up PATH survey,” they said.
Among recent former smokers, 2.2% reported switching to a high-nicotine e-cigarette. Although individuals who switched to e-cigarettes showed a higher rate of relapse to cigarettes than those who did not switch to other tobacco or e-cigarette products, this difference was not significant.
The study findings were limited by several factors including the observational design and inability to control for all potential confounding factors, the researchers noted. However, the results were strengthened by the use of a large and representative study population, and the inclusion of biological samples to validate self-reported smoking, they said.
Several findings surprised study author
Dr. Pierce said he was surprised by several aspects of the study findings.
“First of all, contrary to what we expected, there was a 25% decline in using e-cigarettes to quit, compared to the previous year (not the 40% increase that was expected from the increase in e-cigarette sales) and almost no smokers were using high-nicotine JUUL products to help them quit,” he said. “In this study, e-cigarettes were much less helpful (7 less successful quitters per 100) than pharmaceutical cessation aids in helping people quit,” he added.
“The fact that the proportion of smokers using e-cigarettes for cessation dropped from 17% to 12% was unexpected, and it suggests that the belief that they are a cessation aid is declining,” he said.
The implication for clinical practice is that e-cigarettes are not a useful tool for smoking cessation, Dr. Pierce said. “We are not finding any evidence in this very large nationally representative study that smokers who switch to getting their nicotine from e-cigarettes are less likely to relapse back to cigarette smoking,” he said.
“We don’t know about the high-nicotine versions,” he added.
New review advises against e-cigarettes for cessation
A recent review article published in JAMA supported the use of pharmacotherapy and behavioral support for smokers wanting to quit. In the review, Nancy A. Rigotti, MD, of Massachusetts General Hospital, Boston, and colleagues summarized the evidence for managing tobacco smoking in clinical practice.
“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.
The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.
Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.
With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.
In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.
The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.
Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”
“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
Findings may guide patient conversations
The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.
“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.
Dr. Girgis also said she was not surprised by the findings.
“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.
“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.
With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.
Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.
“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”
“To continue to use e-cigarettes indefinitely should not be the goal,” she added.
The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.
The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group. Lead author Dr. Rigotti disclosed funding from the National Heart, Lung, and Blood Institute and Achieve Life Sciences and personal fees from UpToDate and Achieve Life Sciences. Dr. Girgis had no financial conflicts to disclose.

“The health risk from cigarette smoking is primarily due to chemicals produced by the burning of tobacco and not to nicotine,” they noted. However, the physical dependence on nicotine makes quitting a challenge, but it is one worth pursuing, the authors said.
The authors of this review identified 30 reviews, 12 randomized clinical trials, and 7 recent guidelines and evidence reviews. Their key message: Pharmacotherapy and behavioral support are effective when used alone, but even more effective when combined. Pharmacotherapy helps reduce the symptoms of nicotine withdrawal, while behavioral intervention tackles the challenge of changing learned behaviors associated with smoking, the researchers said.
Although combining medications, such as varenicline and nicotine replacement therapy or bupropion might improve successful quit rates, these combinations have not been well studied, they noted.
With regard to e-cigarettes, the researchers cited a 2021 Cochrane review of 16,759 individuals who used e-cigarettes for smoking cessation, which found no evidence of harm, but insufficient evidence to asses the balance of risks vs. benefits.
In addition to the lack of randomized trials, “the FDA regulates e-cigarettes as tobacco products, not as medical products and has not evaluated any e-cigarette for medical use as a cessation aid,” the authors of the new review noted.
The review was limited by several factors, including the lack of quality assessment for the selected studies and the exclusion of pharmacotherapy not licensed in the United States.
Commenting on the JAMA paper, Dr. Pierce said, “This review looks like a number of Cochrane Reports that have been published recently. Of course, it only considers randomized trials and not population evidence.”
“If public health had limited itself to this form of evidence, then we still would not know that smoking caused cancer,” he noted. “Randomized trials are very important for testing new drugs; they use selected populations and provide considerable support that is not available in the real world. Sometimes they do not generalize to the population.”
Findings may guide patient conversations
The Tobacco Control study was important, because few studies on e-cigarettes have been conducted, said Linda Girgis, MD, a family physician in private practice in South River, N.J., in an interview.
“As clinicians, we do not have a lot of data available in order to make clinical decisions that are evidence based. Also, getting patients to quit smoking is often very difficult, and having more tools available is a great benefit; however, we need to have the evidence that these tools are effective,” she said.
Dr. Girgis also said she was not surprised by the findings.
“Patients still have the same concerns from e-cigarettes regarding nicotine exposure, but just to a lesser degree; and we still don’t know the long-term effects of e-cigarette use, she said. Based on these studies, recommending e-cigarettes for smokers looking to quit may not be the best method, she noted.
“While it may seem reasonable that exposing lungs to lower doses of nicotine will reduce harm, we need to see actual evidence of this. Also, we also need to study the additives that are frequently used in e-cigs, such as artificial flavorings, to see what harms they may pose, she emphasized.
With regard to the JAMA review, Dr. Girgis said she agreed with the recommendations for pharmacotherapy and behavior therapy as first-line treatments for smoking cessation. “There is evidence regarding the efficacy and safety of these methods, and they have been used for decades,” she said.
Dr. Girgis added that there is a role for e-cigarettes in smoking cessation strategies as a method of harm reduction, but pointed out the problem of many people thinking these products are safe and not understanding the hazards they pose.
“They think they can replace smoking with e-cigarettes and be safe from the health risks associated with smoking. I think if the plan were to switch to e-cigarettes for a short period and then quit, there would be a role,” Dr. Girgis said. “However, replacing one risk for another may reduce harm, but doesn’t eliminate it.”
“To continue to use e-cigarettes indefinitely should not be the goal,” she added.
The Tobacco Control study was funded by the National Institutes of Health and the Tobacco-Related Disease Research Program of the University of California. The researchers had no financial conflicts to disclose.
The JAMA study was funded in part by a grant from the National Institute for Health Research, via Cochrane Infrastructure funds to the Cochrane Tobacco Addiction Group. Lead author Dr. Rigotti disclosed funding from the National Heart, Lung, and Blood Institute and Achieve Life Sciences and personal fees from UpToDate and Achieve Life Sciences. Dr. Girgis had no financial conflicts to disclose.

Scientists see hope in new therapy for COVID-19 brain fog patients
People with long-COVID “brain fog” may be able to recover mental abilities that were dulled or stolen from them by the virus through an approach that has improved the effects of stroke, traumatic brain injury, and other post-viral disorders, doctors and scientists say.
For a lucky portion of the population, COVID-19 lasts a handful of days with minor symptoms. But for an estimated 37% who contract the virus, symptoms can linger for weeks, months, or even years. One of the most common symptoms of long COVID is brain fog: a life-altering condition characterized by slow thinking, confusion, difficulty remembering things, and poor concentration.
The approaches are based on the concept of neuroplasticity: The ability of neural networks in the brain to change, adapt, and strengthen, much like a muscle in the body that has been trained and exercised.
“The brain’s ability to bounce back from injury is what neuroplasticity is, and I’ve worked with people in our rehab clinic who have had brain tumors or suffer the effects of surgery or radiation on the brain, and people who have had West Nile virus, HIV, and meningitis,” said Tom Bergquist, PhD, clinical neuropsychologist at Mayo Clinic in Rochester, Minn. “There’s not a week that goes by that I don’t see someone recovering from COVID-19.”
One of the approaches used in the clinic is errorless learning, or having a patient with memory problems repeat information a certain number of times without error. The repetition helps rebuild those memory skills that were weakened during infection, Dr. Bergquist says.
People who have experienced brain fog after other viral infections have seen improvements with these approaches. Ben Ahrens, co-founder and CEO of re-origin – a company that offers neuroplasticity therapy – says he had long-term cognitive issues after a Lyme disease infection. Posttreatment Lyme disease syndrome, or chronic Lyme disease, occurs in about 1 in 10 people who are infected.
Mr. Ahrens says he was struck with Lyme 10 years ago and had brain fog, joint pain, and brain lesions detectable on scans for several years after infection.
According to Mr. Ahrens, neuroplasticity-based therapies help combat what researchers have found may be a lingering memory of past infections that lead to a heightened immune response, causing lingering symptoms.
“Essentially, what we believe is happening here, is the brain has learned that these symptoms are life-threatening – because, in fact, they can be,” Mr. Ahrens said. “The brain’s one job is to protect the body, and once it’s learned to associate these symptoms with that potentially very dangerous pathogen, even after it’s gone, things like a normal headache can trigger an immune cascade.”
Studies are underway at the University of Alabama at Birmingham to examine whether constraint-induced therapy – an approach rooted in neuroplasticity and historically used for loss of limb and speech function – is also effective for cognitive impairments like brain fog.
One technique they use is called shaping, which requires a person to repeatedly carry out their personal best function of impaired use – for example, remembering household tasks they have previously forgotten. That is done multiple times over several weeks in the clinic, and patients are given ways to transfer those skills to real-life use.
So far, the results are promising, said Edward Taub, PhD, researcher and professor of psychology at the University of Alabama at Birmingham.
When used in the past for physical impairments, researchers have noted not just clinical improvements, but structural changes. It led to an increase in the brain’s gray matter – which allows individuals to control movement, memory, and emotions – and improved white matter, which helps communication between gray matter areas.
Though results of the cognitive studies have not been published, Dr. Taub said patients with brain fog have shown improvement after just 35 hours of therapy and are nearly 100% improved after 6 months.
“The idea behind this is that the brain is responsive to use,” Dr. Taub said. “The amount of brain territory that’s dedicated to supporting or mediating a given behavioral function depends on the demands placed on the brain.”

Growth in early life may predict early puberty
Faster gains in weight, length or height, or body mass index in the first 5 years of life were associated with an earlier onset of puberty in boys and girls, based on data from a cohort study of more than 7,000 children.
In recent decades, clinicians and parents have raised concerns about an earlier onset of puberty in children in the United States and other countries, Izzudin M. Aris, PhD, of Harvard Medical School, Boston, and colleagues wrote.
“Children with earlier pubertal onset not only may be at increased risk for long-term chronic diseases, but also may experience adverse consequences during adolescence, including psychosocial difficulties and dysmetabolism,” they said. However, the effect of growth in the first 5 years of life on pubertal onset has not been well studied.
In a study published in JAMA Network Open, the researchers identified 7,495 children from 36 cohorts participating in the Environmental Influences on Child Health Outcomes program from Jan. 1, 1986, to Dec. 31, 2015.
The study population included 3,772 girls and 3,723 boys; 60% reported as White, 23% as Black, 15% as Hispanic, 12% as one of the following: American Indian or Alaska Native, Native Hawaiian or Pacific Islander, multiple races, or other race. Most (84.1%) were born during or after the year 2000.
The primary outcome was the pubertal growth spurt, also known as age at peak height velocity (APHV). The researchers measured growth at 3 age periods in the first 5 years (early infancy, late infancy, and early childhood) and estimated rates of weight, length or height, and body mass index (BMI) gain. Secondary outcomes included self-reported pubic hair staging and scores on the Pubertal Development Scale.
Overall, weight and length or height gain velocities declined in the first 5 years of life, and boys had faster gains in early infancy, compared with girls.
APHV was negatively correlated with puberty scores and Tanner staging for pubic hair development in both boys and girls, while puberty score was positively correlated with Tanner staging for pubic hair in both sexes.
After controlling for maternal and child confounders including maternal age at delivery, maternal education level, and year of birth, faster gains in weight, length or height, or BMI at each of the three measurement periods in early life was associated with earlier APHV in boys. No effect was noted for race, maternal education level, or birth year.
In girls, faster gains in weight, length, or height, only at the latest measurement period (early childhood) were associated with younger APHV. No associations with APHV occurred for velocities of BMI gain at any age period in girls, the researchers noted. However, age at menarche was positively correlated with early APHV and negatively correlated with puberty score and Tanner staging for pubic hair.
The findings support previous studies of associations between child growth and pubertal onset, the researchers wrote. The mechanisms of action are many, and have not been explained, the researchers wrote in their discussion of the findings.
“We speculate that insulinlike growth factor 1 may be a factor in the associations observed in the present study, either directly or indirectly through sex steroid synthesis and secretion. Alternatively, in girls, androgens and adipokines may be factors in the observed associations for pubic hair staging and menarche, respectively,” they said. Genetics and other factors including social factors, environmental exposures, diet, and physical activity also affect growth in early life.
The study findings were limited by several factors including the use of child-reported measures of pubic hair staging and parent reports of pubertal scores, with the potential for error and misclassification, the researchers noted. Other limitations include a lack of data on maternal age at menarche and the use of weight-for-length rather than BMI for children younger than 2 years.
However, the results were strengthened by the large sample size, long-term follow-up, and especially the use of a nationally representative contemporary cohort that addresses gaps in the current literature from later time periods. The results support the associations of sex-specific early pubertal onset in children with faster growth early in life. “In the long term, results of the present study may inform future research that aims to develop and/or test preventive interventions to optimize nutrition, environmental exposures, physical activity, and other behaviors related to growth during these age periods,” they concluded.
Time and timing limit practical application of results
The current study addresses two issues that are ongoing concerns for clinicians, specifically, the rise in obesity in childhood and its potential link to an earlier age of entry into puberty, M. Susan Jay, MD, of the Medical College of Wisconsin, Milwaukee, said in an interview.
“Authors in prior studies have suggested that earlier puberty, and indeed earlier menarche, in females may be associated with the potential of long-term health issues,” Dr. Jay noted. “It has also been suggested that both early maturing females and males may be impacted psychosocially. Others have suggested that the pathways through puberty are key and environmental factors as well as nutrition can have an impact on adolescence as well as health consequences later in life.”
The current study is important because it focused on children born in the present era of the obesity epidemic, while earlier studies were conducted on a group in the 1960s-1980s. “This study suggests that there are sex-specific associations of faster growth and earlier entry into puberty,” Dr. Jay said.
“While it is exciting to consider closer monitoring of pubertal progression in pediatric settings, often patients and families do not present in a timely manner for assessment,” she said. “Also, the authors suggest that preventive support may be offered to children who are traversing puberty at earlier ages. However, given the current stress on practices with COVID as well as stress on providers offering clinical services, identifying supportive interventions may be a stretch at best for practitioners already burdened by clinical and administrative demands.
“Ongoing studies are needed to address the knowledge gaps that exist in the arena of pubertal onset and growth during childhood across life periods,” said Dr. Jay. “In the long term, the present study may help direct research that could focus on preventive interventions to optimize nutrition, physical activity, environmental exposures, and other factors that intersect growth during infancy through early childhood, which may hasten early pubertal development’s later sequelae in adulthood.”
The study was supported by various grants to the researchers from the Environmental Influences on Child Health Outcomes program, Office of the Director, National Institutes of Health, as well as the Colorado Clinical and Translational Sciences Institute, University of Colorado at Denver. Lead author Dr. Aris had no financial conflicts to disclose. Dr. Jay had no conflicts to disclose and serves on the editorial advisory board of Pediatric News.

“Ongoing studies are needed to address the knowledge gaps that exist in the arena of pubertal onset and growth during childhood across life periods,” said Dr. Jay. “In the long term, the present study may help direct research that could focus on preventive interventions to optimize nutrition, physical activity, environmental exposures, and other factors that intersect growth during infancy through early childhood, which may hasten early pubertal development’s later sequelae in adulthood.”
The study was supported by various grants to the researchers from the Environmental Influences on Child Health Outcomes program, Office of the Director, National Institutes of Health, as well as the Colorado Clinical and Translational Sciences Institute, University of Colorado at Denver. Lead author Dr. Aris had no financial conflicts to disclose. Dr. Jay had no conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Endometriosis not linked with preterm birth, new study finds
These new findings, which were published online in JAMA Network Open, suggest that changing monitoring strategies to prevent preterm birth for women with the disease may not be necessary.
The research team, led by Louis Marcellin, MD, PhD, with the department of obstetrics and gynecology at Université de Paris, also found that disease phenotype or whether the preterm birth was induced or spontaneous did not appear to alter the result.
Those results differ from previous research. Data on the phenotypes and their link with preterm birth have been scarce, but previous studies have shown the risk for preterm birth is more pronounced in women who have deep endometriosis than in women with ovarian endometriosis.
Dr. Marcellin said in an interview that “little is known about the impact of endometriosis on obstetric outcomes. In contrast to previous studies, we reported no differences in the risk for preterm delivery between women with endometriosis (34 of 470 [7.2%]) and those without endometriosis (53 of 881 [6.0%]), even when adjusted for multiple factors.”
The authors accounted for mother’s age, body mass index before pregnancy, birth country, number of times the woman had given birth, previous cesarean delivery, and history of preterm birth. After adjusting for potential confounders, endometriosis was not associated with preterm birth (adjusted odds ratio, 1.07; 95% confidence interval, 0.64-1.77).
The researchers found no differences among preterm births based on a mother’s endometriosis phenotype. Those phenotypes include Isolated superficial peritoneal endometriosis, ovarian endometrioma, and deep endometriosis.
“Monitoring pregnancy beyond the normal protocols or changing management strategies may not be warranted in cases of endometriosis,” Dr. Marcellin said.
More research on endometriosis’ potential link to birth outcomes is needed.
An expert not involved with the study said the new paper highlights important new avenues of research but should not be seen as the final word on the connection between endometriosis and preterm birth.
Of the 1,351 study participants (mean age, 32.9 years) who had a singleton delivery after 22 weeks’ gestation, 470 were assigned to the endometriosis group, and 881 were assigned to the control group.
The authors concluded that “pregnant women with endometriosis should not be considered to have an exceptionally high risk for preterm birth. However, further studies are needed to examine the potential for other adverse perinatal outcomes or specific but rare complications.”
Daniela Carusi, MD, said the difficulty with the study’s design is that “premature birth is not one problem or one disease.”
Many very different problems can all end with premature birth. Sometimes it’s an infection or inflammation or bleeding in the uterus or hypertension in the mother, for example, and all those things can lead to a preterm birth, she explained.
“This study inherently lumps all those things together,” said Dr. Carusi, who is director of surgical obstetrics and placental abnormalities in the department of obstetrics and gynecology at Brigham and Women’s Hospital, Boston. “It’s quite possible endometriosis can have a big impact in one of those areas and no impact in the other areas, but the study design wouldn’t be able to pick that up.”
Editorialists: Results challenge findings of previous studies
In an accompanying commentary, Liisu Saavalainen, MD, PhD, and Oskari Heikinheimo, MD, PhD, both with the department of obstetrics and gynecology, Helsinki University Hospital, wrote that several previous studies have suggested that women with endometriosis have a slightly higher risk for preterm birth.
Those studies were mostly retrospective and differed in the way they classified endometriosis and the way they selected patients, the editorialists write. Also, most women in these studies typically had subfertility, they added.
The study by Dr. Marcellin and colleagues differs from previous related research in that was prospective and assessed the risk for preterm delivery in women both with endometriosis and those without endometriosis from several maternity centers in France. The women with endometriosis were classified according to the severity of their disease.
The editorialists wrote: “The novel results by Marcellin et al. challenge the findings of most previous studies on this topic. These results are valuable and comforting. However, they are also likely to trigger new studies on the pregnancy risks associated with different types of endometriosis. That is good news.”
Dr. Carusi said the study was well done and included a notably large size. Further complimenting the research, she said it’s important to talk about this little-discussed pregnancy complication. There’s been much more focus for women with endometriosis and their physicians on getting pregnant and on talking about the length of their term.
The study leaves some things unanswered.
The study was funded by research grants from the French Ministry of Health and was sponsored by the Département de la Recherche Clinique et du Développement de l’Assistance Publique–Hôpitaux de Paris. Dr. Carusi reported no relevant financial relationships. One study coauthor reported receiving personal fees from Bioserinity and Ferring outside the submitted work. No other disclosures were reported.

Goffin’s cockatoo? More like golfin’ cockatoo
Can birds play golf? Of course not; it’s ridiculous. Humans can barely play golf, and we invented the sport. Anyway, moving on to “Brian retraction injury after elective aneurysm clipping.”
Hang on, we’re now hearing that a group of researchers, as part of a large international project comparing children’s innovation and problem-solving skills with those of cockatoos, have in fact taught a group of Goffin’s cockatoos how to play golf. Huh. What an oddly specific project. All right, fine, I guess we’ll go with the golf-playing birds.
Golf may seem very simple at its core. It is, essentially, whacking a ball with a stick. But the Scots who invented the game were undertaking a complex project involving combined usage of multiple tools, and until now, only primates were thought to be capable of utilizing compound tools to play games such as golf.
For this latest research, published in Scientific Reports, our intrepid birds were given a rudimentary form of golf to play (featuring a stick, a ball, and a closed box to get the ball through). Putting the ball through the hole gave the bird a reward. Not every cockatoo was able to hole out, but three did, with each inventing a unique way to manipulate the stick to hit the ball.
As entertaining as it would be to simply teach some birds how to play golf, we do loop back around to medical relevance. While children are perfectly capable of using tools, young children in particular are actually quite bad at using tools to solve novel solutions. Present a 5-year-old with a stick, a ball, and a hole, and that child might not figure out what the cockatoos did. The research really does give insight into the psychology behind the development of complex tools and technology by our ancient ancestors, according to the researchers.
We’re not entirely convinced this isn’t an elaborate ploy to get a bird out onto the PGA Tour. The LOTME staff can see the future headline already: “Painted bunting wins Valspar Championship in epic playoff.”
Work out now, sweat never
Okay, show of hands: Who’s familiar with “Name that tune?” The TV game show got a reboot last year, but some of us are old enough to remember the 1970s version hosted by national treasure Tom Kennedy.
The contestants try to identify a song as quickly as possible, claiming that they “can name that tune in five notes.” Or four notes, or three. Well, welcome to “Name that exercise study.”
Senior author Masatoshi Nakamura, PhD, and associates gathered together 39 students from Niigata (Japan) University of Health and Welfare and had them perform one isometric, concentric, or eccentric bicep curl with a dumbbell for 3 seconds a day at maximum effort for 5 days a week, over 4 weeks. And yes, we did say 3 seconds.
“Lifting the weight sees the bicep in concentric contraction, lowering the weight sees it in eccentric contraction, while holding the weight parallel to the ground is isometric,” they explained in a statement on Eurekalert.
The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%. After a total of just 60 seconds of exercise in 4 weeks. That’s 60 seconds. In 4 weeks.
Big news, but maybe we can do better. “Tom, we can do that exercise in 2 seconds.”
And one! And two! Whoa, feel the burn.
Tingling over anxiety
Apparently there are two kinds of people in this world. Those who love ASMR and those who just don’t get it.
ASMR, for those who don’t know, is the autonomous sensory meridian response. An online community has surfaced, with video creators making tapping sounds, whispering, or brushing mannequin hair to elicit “a pleasant tingling sensation originating from the scalp and neck which can spread to the rest of the body” from viewers, Charlotte M. Eid and associates said in PLOS One.
The people who are into these types of videos are more likely to have higher levels of neuroticism than those who aren’t, which gives ASMR the potential to be a nontraditional form of treatment for anxiety and/or neuroticism, they suggested.
The research involved a group of 64 volunteers who watched an ASMR video meant to trigger the tingles and then completed questionnaires to evaluate their levels of neuroticism, trait anxiety, and state anxiety, said Ms. Eid and associates of Northumbria University in Newcastle-upon-Tyne, England.
The people who had a history of producing tingles from ASMR videos in the past had higher levels of anxiety, compared with those who didn’t. Those who responded to triggers also received some benefit from the video in the study, reporting lower levels of neuroticism and anxiety after watching, the investigators found.
Although people who didn’t have a history of tingles didn’t feel any reduction in anxiety after the video, that didn’t stop the people who weren’t familiar with the genre from catching tingles.
So if you find yourself a little high strung or anxious, or if you can’t sleep, consider watching a person pretending to give you a makeover or using fingernails to tap on books for some relaxation. Don’t knock it until you try it!
Living in the past? Not so far-fetched
It’s usually an insult when people tell us to stop living in the past, but the joke’s on them because we really do live in the past. By 15 seconds, to be exact, according to researchers from the University of California, Berkeley.
But wait, did you just read that last sentence 15 seconds ago, even though it feels like real time? Did we just type these words now, or 15 seconds ago?
Think of your brain as a web page you’re constantly refreshing. We are constantly seeing new pictures, images, and colors, and your brain is responsible for keeping everything in chronological order. This new research suggests that our brains show us images from 15 seconds prior. Is your mind blown yet?
“One could say our brain is procrastinating. It’s too much work to constantly update images, so it sticks to the past because the past is a good predictor of the present. We recycle information from the past because it’s faster, more efficient and less work,” senior author David Whitney explained in a statement from the university.
It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.
And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.
And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?
Substantial numbers of U.S. youth report vaping cannabis
Adolescents and young adults who use e-cigarettes reported vaping cannabis, according to selected data from the national Population Assessment of Tobacco and Health (PATH) study.
Ruoyan Sun, PhD, an assistant professor at the University of Alabama at Birmingham, and colleagues examined results of PATH’s wave5 survey conducted from December 2018 to November 2019. PATH is a National Institutes of Health–Food and Drug Administration collaboration begun in 2013.
Their analysis, published online Feb. 7, 2022, in JAMA Pediatrics, evaluated the frequency of cannabis vaping across several age groups: 164 respondents ages 12-14; 919 participants ages 15-17; and 3,038 participants ages 18-24. Respondents included for analysis reported electronic nicotine product consumption in the past 30 days. In response to the question “When you have used an electronic product, how often were you using it to smoke marijuana, marijuana concentrates, marijuana waxes, THC, or hash oils?” 35.0% (95% confidence interval, 29.3%-41.2%) of current e-smokers aged 12-14 years said they had done so, as did 51.3% (95% CI, 47.7%-54.9%) of those aged 15-17 years and 54.6% (95% CI, 52.5%-56.7%) of young adults aged 18-24.
The prevalence of those who reported vaping cannabis every time they vaped was 3.1% (95% CI, 1.3%-6.9%) of youths aged 12-14 years, 6.7% (95% CI, 5.3%-8.6%) of youths aged 15-17 years, and 10.3% (95% CI, 9.0%-11.6%) of young adults aged 18-24.
Among children ages 12-14, 65% said they never vaped cannabis, while 48.7% and 45.4%, respectively, in the two older groups said they did.
“This is a very important finding and it mirrors what some of us have already seen in practice,” said pediatric pulmonologist S. Christy Sadreameli, MD, MHS, an assistant professor of pediatrics at John Hopkins University, Baltimore. “It is important for pediatricians to realize that dual use of cannabis and nicotine vaping, and exclusive use of cannabis vaping, are not uncommon. It informs how we ask questions and how we counsel our patients.” Dr. Sadreameli was not involved in the PATH study.
Overall, the survey participants were 56% male, with 24% of respondents identifying as Hispanic, 8% as non-Hispanic Black, 58% as non-Hispanic White, and 10% as of other race/ethnicity. The weighted proportion of current e-cigarette use was 3.0% (95% CI, 2.6%-3.4%) in youths ages 12-14 years, 14.4% (95% CI, 13.5%-15.3%) in those 15-17 years, and 26.2% (95% CI, 25.3%-27.1%) in young adults.
Other recent national surveys such as the National Institute on Drug Abuses’s Monitoring the Future are reporting a growing prevalence of youth cannabis vaping, Dr. Sun said. For example, the prevalence of cannabis vaping in the past 12-month period among grade 12 students grew from 9.5% in 2017 to 22.1% in 2020. Vaping cannabis was more prevalent among Hispanic teens than other ethnicities.
Vaping devices such as e-cigarettes, vaping pens, e-cigars, and e-hookahs can be used to inhale multiple substances, including nicotine, cannabis, and opium, Dr. Sun noted in an interview. “So in addition to asking about the behavior of vaping itself, pediatricians could pay more attention to what is being vaped in these devices.”
According to Dr. Sadreameli, vaping more than one substance at a time could potentially work synergistically to cause more harm, compared with one product alone. “The other aspect to consider is that vaping multiple types of products may increase the chance of harm from other components of the mixture,” she said. For instance, a lot of the e-cigarette or vaping use-associated lung injury (EVALI) cases have been linked to vitamin E acetate, which was found in certain cannabis formulations. “Anecdotally, most EVALI patients I’ve met seemed to report use of multiple products, including cannabis-containing and nicotine-containing products.”
Dr. Sadreameli added that some cannabis vapers will have other issues. “For example, there is a severe vomiting syndrome I’ve seen, which is induced by cannabis and improved by cessation from cannabis,” she said. “It is important for pediatricians to ask the right questions of their patients in order to better understand what they may be experiencing, provide counseling, and to help them.”
A related issue is cessation, she said. “For those working to achieve cessation from nicotine-based products, sometimes nicotine replacement therapies are helpful. However, cessation from cannabis-containing products is going to look different.”
Although the study did not yield information on the prevalence simultaneous nicotine/cannabis vaping, the authors suggested that some vapers may be combining substances. Previous studies may have modestly overestimated the prevalence of nicotine vaping given their finding that some current e-cigarette users reported vaping cannabis every time they vaped and may be vaping cannabis exclusively. “However, if some current users vaped nicotine and cannabis simultaneously, then overestimation of nicotine vaping would be smaller,” they wrote.
Future surveys on this area should contain detailed questions on nicotine and cannabis vaping, including the substance being vaped and the frequency and intensity of use, Dr. Sun said. “In addition, these surveys could examine some other substances that are being vaped, such as opium and cocaine.”
The PATH study is supported by the NIH, National Institute on Drug Abuse, Department of Health & Human Services, and the FDA’s Center for Tobacco Products. The authors and Dr. Sadreameli had no competing interests to disclose.

Expert shares workup pearls for children with severe atopic dermatitis
“Many patients who have failed topical steroids have never had adequate treatment,” Anna Yasmine Kirkorian, MD, chief of dermatology at National Children’s Hospital in Washington, said during the ODAC Dermatology, Aesthetic & Surgical Conference. “There is no lower age limit on the use of topical corticosteroids, and low potency corticosteroids are inadequate to treat severe eczema. The idea that only over-the-counter 2.5% hydrocortisone cream is necessary is not true,” she added.
“You also want to scrutinize the vehicle,” she said, noting that children are often prescribed cream formulations that hurt when applied, so parents stop applying them. “Ointments are generally the vehicles of choice in childhood,” she added.
It is generally not advised to use topical and oral antibiotics in children with AD, unless there are clear signs of infection. “If they’re just slightly oozy, don’t use them,” she continued. “Of course, every child or adult with eczema has Staph aureus on them, but most of the time, what you need to do is repair the barrier. We know that from data and common sense. When we repair their barrier, their rates of infection decrease.”
A focal area with pustules and pus should be cultured and treated, Dr. Kirkorian said. “Monotherapy with antibiotics is going to do nothing for you.” In cases of children with failure to thrive, she recommends referral to pediatric dermatology, allergy/immunology, GI, or genetics, as appropriate.
For children with severe AD, Dr. Kirkorian favors a rescue plan with a one-pound jar of triamcinolone ointment 0.1%. She recommends application of the ointment to all areas, including the face and scalp once nightly for 2 weeks, with a follow-up appointment at the end of that time. “If you just give people medicine and ask them to come back in 6 months, they are not able to comply with that and they don’t have faith that it’s going to work,” explained Dr. Kirkorian, associate professor of dermatology and pediatrics at George Washington University, Washington. At the end of 2 weeks, “the majority will have improved dramatically, and then you can implement maintenance therapy with topical calcineurin inhibitors, crisaborole, or possibly topical ruxolitinib.”
Some clinicians prescribe oral antihistamines for AD, but Dr. Kirkorian said that data supporting their use are limited and antihistamines are not approved for use in children younger than 6 months of age. Sedating antihistamines will induce sleep, “but do not provide durable night-long sleep,” and routine use may have an impact on learning and school performance. In addition, exposure to antihistamines in children under age 2 may be associated with development of ADHD at school age.
The interleukin-4 receptor alpha antagonist dupilumab (Dupixent) is approved by the Food and Drug Administration for moderate to severe AD in patients ages 6 and older. But obtaining it for patients can be tricky, she said, as this requires documented failure of corticosteroids, calcineurin inhibitors, crisaborole ointment, and phototherapy (if prescribed). Patients are often obligated to do step therapy with an off-label drug such as cyclosporine or methotrexate for 3 months, and they need to demonstrate responses with objective measures of severity such as the SCORAD (SCORing Atopic Dermatitis) and the validated Investigator Global Assessment.
“Most of my patients carry insurance that does not approve dupilumab without failure of a prior off-label systemic immunosuppressant medication,” Dr. Kirkorian said. Cyclosporine is her first choice for a systemic immunosuppressant “because it has a fast onset of action, it’s effective for treatment of atopic dermatitis, and safe for short-term use,” she said. “I don’t think that methotrexate works well for eczema. It can take weeks and weeks to work.”
She typically starts patients on a 5 mg/kg dose of cyclosporine. Baseline tests include CBC, CMP (comprehensive metabolic panel), lipids, and vitals. She repeats the labs at 1 month, and includes a blood pressure check. Potential adverse effects of cyclosporine include infections (including opportunistic infections), cytopenias, hypertension, nephrotoxicity, hepatotoxicity, neurotoxicity (including posterior reversible encephalopathy syndrome), electrolyte disturbance, lymphoma, and cutaneous malignancy.
“The good news is that we generally don’t see the adverse effects with short-term use,” Dr. Kirkorian said. “We will see some hypertrichosis and gingival hypertrophy, which resolves with cessation of therapy. There are serious side effects if you use it for long enough.”
As for methotrexate, “it is still a very important drug in pediatric dermatology, particularly in other conditions such as psoriasis,” she said. “The problem is that weekly dosing of methotrexate poses a greater risk of dosing errors. People aren’t really triggered to think of a once-weekly medication. If you do use it, give them a short supply to make sure that they come back, and that they don’t give it daily accidentally.”
Practical tips she offered for prescribing cyclosporine include supplying a patient handout with information on all adverse effects, dosing information, vaccination information, and pregnancy precautions, with contact information (a patient portal or on-call number) for the treating clinician in case a patient develops adverse effects. Administration of live vaccines while patients are on cyclosporine is not recommended.
When transitioning patients from cyclosporine or methotrexate to dupilumab, Dr. Kirkorian recommends tapering the immunosuppressant dose by half every 2 weeks to complete cessation by week 8 of treatment. For patients who experience a severe baseline flare once the immunosuppressant is tapered, despite the switch to dupilumab, she recommends restarting methotrexate at a full dose and then reducing the dose every 2 weeks until the lowest effective dose (2.5-5 mg weekly) is reached.
“Waning efficacy is real,” she said. “We can add methotrexate to recapture efficacy. Check for superimposed allergic contact dermatitis.”
With upadacitinib (Rinvoq), an oral Janus kinase (JAK) inhibitor recently approved for treating refractory, moderate to severe AD in patients 12 years of age and older, is the risk profile acceptable to parents and physicians? “I think the answer is yes,” Dr. Kirkorian said. “But we’re going to have to think through that very carefully. It’s going to be exciting to see how this drug changes management in our patients.”
Dr. Kirkorian disclosed that she is a member of the advisory board for Verrica Pharmaceuticals.

Cyclosporine is her first choice for a systemic immunosuppressant “because it has a fast onset of action, it’s effective for treatment of atopic dermatitis, and safe for short-term use,” she said. “I don’t think that methotrexate works well for eczema. It can take weeks and weeks to work.”
She typically starts patients on a 5 mg/kg dose of cyclosporine. Baseline tests include CBC, CMP (comprehensive metabolic panel), lipids, and vitals. She repeats the labs at 1 month, and includes a blood pressure check. Potential adverse effects of cyclosporine include infections (including opportunistic infections), cytopenias, hypertension, nephrotoxicity, hepatotoxicity, neurotoxicity (including posterior reversible encephalopathy syndrome), electrolyte disturbance, lymphoma, and cutaneous malignancy.
“The good news is that we generally don’t see the adverse effects with short-term use,” Dr. Kirkorian said. “We will see some hypertrichosis and gingival hypertrophy, which resolves with cessation of therapy. There are serious side effects if you use it for long enough.”
As for methotrexate, “it is still a very important drug in pediatric dermatology, particularly in other conditions such as psoriasis,” she said. “The problem is that weekly dosing of methotrexate poses a greater risk of dosing errors. People aren’t really triggered to think of a once-weekly medication. If you do use it, give them a short supply to make sure that they come back, and that they don’t give it daily accidentally.”
Practical tips she offered for prescribing cyclosporine include supplying a patient handout with information on all adverse effects, dosing information, vaccination information, and pregnancy precautions, with contact information (a patient portal or on-call number) for the treating clinician in case a patient develops adverse effects. Administration of live vaccines while patients are on cyclosporine is not recommended.
When transitioning patients from cyclosporine or methotrexate to dupilumab, Dr. Kirkorian recommends tapering the immunosuppressant dose by half every 2 weeks to complete cessation by week 8 of treatment. For patients who experience a severe baseline flare once the immunosuppressant is tapered, despite the switch to dupilumab, she recommends restarting methotrexate at a full dose and then reducing the dose every 2 weeks until the lowest effective dose (2.5-5 mg weekly) is reached.
“Waning efficacy is real,” she said. “We can add methotrexate to recapture efficacy. Check for superimposed allergic contact dermatitis.”
With upadacitinib (Rinvoq), an oral Janus kinase (JAK) inhibitor recently approved for treating refractory, moderate to severe AD in patients 12 years of age and older, is the risk profile acceptable to parents and physicians? “I think the answer is yes,” Dr. Kirkorian said. “But we’re going to have to think through that very carefully. It’s going to be exciting to see how this drug changes management in our patients.”
Dr. Kirkorian disclosed that she is a member of the advisory board for Verrica Pharmaceuticals.

Agreement reached for research definition of ‘long COVID’ in children and young people
Long COVID can affect adults, young people, and children, and now for the first time, in a landmark study accepted for publication in the Archives of Disease in Childhood, formal agreement has been made on a research definition for post–acute COVID-19, or “long COVID” as it is commonly known, in children and young people.
The researchers charged themselves with a single objective – to derive a research definition for long COVID (post–acute COVID-19) in children and young people to allow comparisons between research studies. Specifically, so studies on prevalence, course, and outcome of long COVID in this age group can be reliably compared, because to date there has been no consensus. In fact, the authors pointed out how the “slew of definitions” currently used all differ in number, type, and duration of symptoms, which hampers research efforts. In addition, the lack of definition consensus has contributed to very wide reported variations in the estimated prevalence of long COVID in children of 1%-51%, with the authors saying that a “consistently applied definition of long COVID will help reduce the variability of prevalence estimates.”
Statements sequentially whittled down
“Using robust consensus methodology,” the authors said, “we derived a research definition for long COVID in children and young people.”
To achieve the definition consensus, a three-phase online Delphi process was used, followed by a virtual consensus meeting. The 123 participants registered to take part in the study included 23 people (19%) in a lived experience panel, 50 (42%) in the researcher or researcher/service delivery combined panel and 47 (39%) in the service delivery panel. Of 120 registered participants, 105 (88%) completed phase 1, 86 eligible participants (82% of those completing phase 1) completed phase 2 and 77 eligible participants (90% of those completing phase 2) completed phase 3. Seventeen participants attended and voted at the consensus meeting – 4 (23%) from the service delivery panel, 11 (65%) from the researcher panel, and 2 (12%) from the lived experience panel.
Presented with 49 statements in each phase, participants scored these from 1-9 based on how important they were perceived to be with regards inclusion in the research definition of long COVID in children and young people. Having been sequentially whittled down in three phases, 10 statements were discussed at the consensus meeting, and a panel of eight 11- to 17-year-olds affected by long COVID also reviewed the statements to reach a final agreement.
Five of the statements were agreed to be included in the definition, which stated that long COVID in children and young people is a condition in which a child or young person has symptoms (at least one of which is a physical symptom) that have continued or developed after a diagnosis of COVID-19 (confirmed with one or more positive COVID tests); impact their physical, mental, or social well-being; are interfering with some aspect of daily living (for example, school, work, home, or relationships); and persist for a minimum duration of 12 weeks after initial testing for COVID-19 (even if symptoms have waxed and waned over that period).
David Strain, MBChB, MD, chair of the BMA board of science and clinical senior lecturer and honorary consultant, University of Exeter (England), told the Science Media Centre: “A Delphi study builds a consensus from the world’s experts by presenting a series of statements and continuing to refine them until there is agreement as to what the definition of pediatric long COVID should be.” He added: “This is vitally important in order to align the global research effort into long COVID.”
Reassuringly similar
From the agreed five statements, a further research definition was proposed to align with the World Health Organization definition for adults: “Post–COVID-19 condition occurs in young people with a history of confirmed SARS CoV-2 infection, with at least one persisting physical symptom for a minimum duration of 12 weeks after initial testing that cannot be explained by an alternative diagnosis. The symptoms have an impact on everyday functioning, may continue or develop after COVID-19 infection, and may fluctuate or relapse over time.”
The authors concluded: “This is the first research definition of long COVID (post–COVID-19 condition) in children and young people and complements the clinical case definition in adults proposed by WHO,” adding that the two definitions are “reassuringly similar.”
They reiterated how widespread adoption of this definition would allow comparisons between studies such that a core outcome set can be developed and the prevalence, course and outcome of long COVID in children and young people can be reliably evaluated, which “will substantially help strengthen the evidence base on this debilitating condition.”
In addition, the authors said that a consistently applied definition of long COVID will help to provide a “more accurate picture on the true impact of the condition.”
The researchers emphasized the need to differentiate between a clinical case definition and a research definition of long COVID and explained: “It is understandable that the patient groups representing people with long COVID are concerned about a definition that could restrict access to services that are needed.”
They went on to say that in their view the decision whether a child or young person can see a health care professional, access any support needed, or be referred, investigated, or treated for long COVID should be a “shared decision involving the young person, their carers, and clinicians.”
Dr. Strain reinforced that it was important that the definition was a research one and not a clinical one, pointing out that the 12-week period in the research definition “does not necessarily mean that a child or young person should need to wait 3 months before being offered help or assistance from their health care team, indeed a 3-month delay in offering support to a child or young person, at this vitally important period of their educational development, could have lasting long-term impacts.”
