Symptom timelines surrounding COVID infection tend to center on either the immediate 5-day quarantine protocols for acute infection or the long-COVID symptoms that can last a month or potentially far longer.

But some patients report a “middle-range” COVID that will resolve before it becomes long COVID, yet still lasts longer than is typical for viral infections. People may return to work or daily routines, but something is off: What had been simple exercise regimens become onerous. Everyday tasks take more effort.

Does this ill-defined subset point to a “medium COVID?”

Farha Ikramuddin, MD, MHA, a physiatrist and rehabilitation specialist at the University of Minnesota and M Health Fairview in Minneapolis, points out there is no definition or diagnostic code or shared official understanding of a middle category for COVID.

“But am I seeing that? Absolutely,” she said in an interview.

“I have seen patients who are younger, healthier, [and] with not so many comorbidities have either persistence of symptoms or reappearance after the initial infection is done,” she said.

Some patients report they had very low infection or were nonsymptomatic and returned to their normal health fairly quickly after infection. Then a week later they began experiencing fatigue, lost appetite, loss of smell, and feeling full after a few bites, Dr. Ikramuddin said.

Part of the trouble in categorizing the space between returning to normal after a week and having symptoms for months is that organizations can’t agree on a timeline for when symptoms warrant a “long-COVID” label.

For instance, the Centers for Disease Control and Prevention defines it as 4 or more weeks after infection. The World Health Organization defines it as starting 3 months after COVID-19 symptom onset.

“I’m seeing ‘medium COVID’ – as one would call it – in younger and healthier patients. I’m also noticing that these symptoms are not severe enough to warrant stopping their job or changing their job schedules,” Dr. Ikramuddin said.

They go back to work, she said, but start noticing something is off.

“I am seeing that.”

“I discharge at least two patients a week from my clinic because they have moved on and no longer have symptoms,” Dr. Ikramuddin said.

In a story from Kaiser Health News published last month, WHYY health reporter Nina Feldman writes: “What I’ve come to think of as my ‘medium COVID’ affected my life. I couldn’t socialize much, drink, or stay up past 9:30 p.m. It took me 10 weeks to go for my first run – I’d been too afraid to try.”

She described a dinner with a friend after ending initial isolation protocols: “One glass of wine left me feeling like I’d had a whole bottle. I was bone-achingly exhausted but couldn’t sleep.”
 

Medical mystery

Dr. Ikramuddin notes the mechanism behind prolonged COVID-19 symptoms is still a medical mystery.

“In one scenario,” she said, “the question is being asked about whether the virus is staying dormant, similar to herpes zoster or HIV.”

“Right now, instead of getting more answers, we’re getting more questions,” Dr. Ikramuddin  said.

Mouhib Naddour, MD, a pulmonary specialist with Sharp HealthCare in San Diego, said he’s seeing that it’s taking some patients who have had COVID longer to recover than it would for other viral infections.

Some patients fall between those recovering within 2-3 weeks and patients having long COVID. Those patients in the gap could be lumped into a middle-range COVID, he told this news organization.

“We try to put things into tables and boxes but it is hard with this disease,” Dr. Naddour said.

He agrees there’s no medical definition for “medium” COVID, but he said the idea should bring hope for patients to know that, if their symptoms are persisting they don’t necessarily have long COVID – and their symptoms may still disappear.

“This is an illness that may take longer to completely recover from,” he said. “The majority of patients we’re seeing in this group could be healthy young patients who get COVID, then 2-3 weeks after they test negative, still have lingering symptoms.”
 

Common symptoms

Some commonly reported symptoms of those with enduring illness, which often overlap with other stages of COVID, are difficulty breathing, chest tightness, dry cough, chest pain, muscle and joint pain, fatigue, difficulty sleeping, and mood swings, Dr. Naddour said. 

“We need to do an extensive assessment to make sure there’s no other problem causing these symptoms,” he said.

Still, there is no set timeline for the medium-COVID range, he noted, so checking in with a primary care physician is important for people experiencing symptoms.
 

It’s a continuum, not a category

Fernando Carnavali, MD, coordinator for Mount Sinai’s Center for Post-COVID Care in New York, said he is not ready to recognize a separate category for a “medium” COVID.

He noted that science can’t even agree on a name for lasting post-COVID symptoms, whether it’s “long COVID” or “long-haul COVID,” “post-COVID syndrome” or “post-acute sequelae of COVID-19 (PASC ).” There’s no agreed-upon pathophysiology or biomarker.

“That creates these gaps of understanding on where we are,” Dr. Carnavali said in an interview.

He said he understands people’s need to categorize symptoms, but rather than a middle ground he sees a continuum.

It doesn’t mean what others may call COVID’s middle ground doesn’t exist, Dr. Carnavali said: “We are in the infancy of defining this. Trying to classify them may create more anxiety.”

The clinicians interviewed for this story report no relevant financial relationships.

New surveillance data from the Vaccine Adverse Event Reporting System (VAERS) confirm a small but statistically significant increased risk for Guillain-Barré syndrome (GBS) in the 3 weeks after receipt of the Janssen/Johnson & Johnson COVID-19 vaccine.

The Janssen vaccine (Ad26.COV2.S) is a replication-incompetent adenoviral vector vaccine.

The data show no increased risk of GBS with the Pfizer (BNT162b2) or Moderna (mRNA-1273) shots – both mRNA vaccines.

“Our findings support the current guidance from U.S. health officials that preferentially recommend use of mRNA COVID-19 vaccines for primary and booster doses,” Nicola Klein, MD, PhD, with Kaiser Permanente Vaccine Study Center, Oakland, Calif., told this news organization.

“Individuals who choose to receive Janssen/J&J COVID-19 vaccine should be informed of the potential safety risks, including GBS,” Dr. Klein said.

The study was published online in JAMA Network Open.
 

Eleven cases

Between mid-December 2020 and mid-November 2021, roughly 15.1 million doses of COVID-19 vaccine were administered to nearly 7.9 million adults in the United States.

This includes roughly 483,000 doses of the Janssen vaccine, 8.8 million doses of the Pfizer vaccine, and 5.8 million doses of the Moderna vaccine.

The researchers confirmed 11 cases of GBS after the Janssen vaccine.

The unadjusted incidence of GBS (per 100,000 person-years) was 32.4 in the first 21 days after the Janssen vaccine – substantially higher than the expected background rate of 1 to 2 cases per 100,000 person-years.

There were 36 confirmed cases of GBS after mRNA vaccines. The unadjusted incidence in the first 21 days after mRNA vaccination was 1.3 per 100,000 person-years, similar to the overall expected background rate.

In an adjusted head-to-head comparison, GBS incidence during the 21 days after receipt of the Janssen vaccine was 20.6 times higher than the GBS incidence during the 21 days after the Pfizer or Moderna mRNA vaccines, amounting to 15.5 excess cases per million Janssen vaccine recipients.

Most cases of GBS after the Janssen vaccine occurred during the 1- to 21-day risk interval, with the period of greatest risk in the 1-14 days after vaccination.

The findings of this analysis of surveillance data of COVID-19 vaccines are “consistent with an elevated risk of GBS after primary Ad26.COV2.S vaccination,” the authors wrote.
 

Novel presentation?

The researchers note that nearly all individuals who developed GBS after the Janssen vaccine had facial weakness or paralysis, in addition to weakness and decreased reflexes in the limbs, suggesting that the presentation of GBS after COVID-19 adenoviral vector vaccine may be novel.

“More research is needed to determine if the presentation of GBS after adenoviral vector vaccine differs from GBS after other exposures such as Campylobacter jejuni, and to investigate the mechanism for how adenoviral vector vaccines may cause GBS,” Dr. Klein and colleagues said.

“The Vaccine Safety Datalink continues to conduct safety surveillance for all COVID-19 vaccines, including monitoring for GBS and other serious health outcomes after vaccination,” Dr. Klein said in an interview.

This study was supported by the Centers for Disease Control and Prevention. Dr. Klein reported receiving grants from Pfizer research support for a COVID vaccine clinical trial as well as other unrelated studies, grants from Merck, grants from GlaxoSmithKline, grants from Sanofi Pasteur, and grants from Protein Science (now Sanofi Pasteur) outside the submitted work.

Mental disorders were significantly more likely in children whose mothers had one of five common autoimmune diseases, a new study found.

Previous research has linked both maternal and paternal autoimmune diseases and specific mental disorders, such as attention-deficit/hyperactivity disorder (ADHD), but most of these studies focused on specific conditions in relatively small populations. The new study included data on more than 2 million births, making it one of the largest efforts to date to examine the association, according to the researchers, whose findings were published in JAMA Network Open.

Previous evidence of the possible association between certain maternal autoimmune diseases and mental disorders in offspring has been “scattered and limited,” which “hampered an overall understanding” of the link, Fei Li, MD, the corresponding author of the study, told this news organization.

Dr. Li, of Shanghai Jiao Tong University China, and colleagues reviewed data from a Danish registry cohort of singleton births with up to 38 years of follow-up. They explored associations between a range of maternal autoimmune diseases diagnosed before childbirth and the risks of mental disorders in children in early childhood through young adulthood.

The study population included 2,254,234 births and 38,916,359 person-years. Data on mental health were collected from the Psychiatric Central Research Register and the country’s National Patient Register. The median age of the children at the time of assessment was 16.7 years; approximately half were male.

A total of 50,863 children (2.26%) were born to mothers who had been diagnosed with autoimmune diseases before childbirth. During the follow-up period, 5,460 children of mothers with autoimmune diseases and 303,092 children of mothers without autoimmune diseases were diagnosed with a mental disorder (10.73% vs. 13.76%), according to the researchers.

The risk of being diagnosed with a mental disorder was significantly higher among children of mothers with any autoimmune disease (hazard ratio [HR,], 1.16), with an incidence of 9.38 vs. 7.91 per 1,000 person-years, the researchers reported.

The increased risk persisted when the results were classified by organ system, including connective tissue (HR, 1.11), endocrine (HR, 1.19), gastrointestinal (HR, 1.11), blood (HR, 1.10), nervous (HR, 1.17), and skin (HR, 1.19).

The five autoimmune diseases in mothers that were most commonly associated mental health disorders in children were type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and psoriasis vulgaris.

The greatest risk for children of mothers with any autoimmune disease was observed for organic conditions such as delirium, (HR, 1.54), followed by obsessive-compulsive disorder (HR, 1.42), schizophrenia (HR, 1.54), and mood problems (HR, 1.12).

Children of mothers with any autoimmune disorder also had a significantly increased risk of autism (HR, 1.21), intellectual disability (HR, 1.19), and ADHD (HR, 1.19).

The results add to evidence that activation of the maternal immune system may drive changes in the brain and behavioral problems, which has been observed in animal studies, the researchers wrote.

Potential underlying mechanisms in need of more exploration include genetic risk factors, maternal transmission of autoantibodies to the fetus during pregnancy, and the increased risk of obstetric complications, such as preterm birth, for women with autoimmune disorders that could affect mental development in children, they added.

The study findings were limited by several factors, including the lack of data on potential exacerbation of autoimmune disease activity during pregnancy and its effect on the fetus, the researchers noted. Other limitations included potential detection bias, lack of data on mental disorders in adulthood, and potential changes in diagnostic criteria over the long study period.

The results were strengthened by the use of a population-based registry, the large sample size, and ability to consider a range of confounders, the researchers said.

“This study could help acquire a comprehensive compilation of the associations between maternal autoimmune disorders diagnosed before childbirth and offspring’s mental disorders from childhood through early adulthood,” Dr. Li said in an interview.

For clinicians, Dr. Li said, the findings suggest that the offspring of mothers with autoimmune diseases may benefit from long-term surveillance for mental health disorders.

“Further studies should provide more evidence on the detailed associations of specific maternal autoimmune diseases with a full spectrum of mental disorders in offspring, and more research on underlying mechanisms is needed as well,” she said.
 

Pay early attention

M. Susan Jay, MD, an adjunct professor of pediatrics at the Medical College of Wisconsin, Milwaukee, said previous efforts to examine the association between maternal autoimmunity were hampered by study design, small samples, and self-report of disease history – problems the new research avoids.

The large patient population allowed for detailed subgroup analysis of different conditions and outcomes. Another advantage was the availability of sociodemographic and clinical information, which allowed for the elimination of confounding factors, said Dr. Jay, who was not involved in the research.

“It would be prudent to follow children of mothers with autoimmune disorders before or during pregnancy for mental health issues, and if identified clinically, to offer psychological and developmental behavioral support options,” Dr. Jay added.

The authors have reported no relevant financial relationships.

The risk of being diagnosed with a mental disorder was significantly higher among children of mothers with any autoimmune disease (hazard ratio [HR,], 1.16), with an incidence of 9.38 vs. 7.91 per 1,000 person-years, the researchers reported.

The increased risk persisted when the results were classified by organ system, including connective tissue (HR, 1.11), endocrine (HR, 1.19), gastrointestinal (HR, 1.11), blood (HR, 1.10), nervous (HR, 1.17), and skin (HR, 1.19).

The five autoimmune diseases in mothers that were most commonly associated mental health disorders in children were type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and psoriasis vulgaris.

The greatest risk for children of mothers with any autoimmune disease was observed for organic conditions such as delirium, (HR, 1.54), followed by obsessive-compulsive disorder (HR, 1.42), schizophrenia (HR, 1.54), and mood problems (HR, 1.12).

Children of mothers with any autoimmune disorder also had a significantly increased risk of autism (HR, 1.21), intellectual disability (HR, 1.19), and ADHD (HR, 1.19).

The results add to evidence that activation of the maternal immune system may drive changes in the brain and behavioral problems, which has been observed in animal studies, the researchers wrote.

Potential underlying mechanisms in need of more exploration include genetic risk factors, maternal transmission of autoantibodies to the fetus during pregnancy, and the increased risk of obstetric complications, such as preterm birth, for women with autoimmune disorders that could affect mental development in children, they added.

The study findings were limited by several factors, including the lack of data on potential exacerbation of autoimmune disease activity during pregnancy and its effect on the fetus, the researchers noted. Other limitations included potential detection bias, lack of data on mental disorders in adulthood, and potential changes in diagnostic criteria over the long study period.

The results were strengthened by the use of a population-based registry, the large sample size, and ability to consider a range of confounders, the researchers said.

“This study could help acquire a comprehensive compilation of the associations between maternal autoimmune disorders diagnosed before childbirth and offspring’s mental disorders from childhood through early adulthood,” Dr. Li said in an interview.

For clinicians, Dr. Li said, the findings suggest that the offspring of mothers with autoimmune diseases may benefit from long-term surveillance for mental health disorders.

“Further studies should provide more evidence on the detailed associations of specific maternal autoimmune diseases with a full spectrum of mental disorders in offspring, and more research on underlying mechanisms is needed as well,” she said.
 

Pay early attention

M. Susan Jay, MD, an adjunct professor of pediatrics at the Medical College of Wisconsin, Milwaukee, said previous efforts to examine the association between maternal autoimmunity were hampered by study design, small samples, and self-report of disease history – problems the new research avoids.

The large patient population allowed for detailed subgroup analysis of different conditions and outcomes. Another advantage was the availability of sociodemographic and clinical information, which allowed for the elimination of confounding factors, said Dr. Jay, who was not involved in the research.

“It would be prudent to follow children of mothers with autoimmune disorders before or during pregnancy for mental health issues, and if identified clinically, to offer psychological and developmental behavioral support options,” Dr. Jay added.

The authors have reported no relevant financial relationships.

Mental disorders were significantly more likely in children whose mothers had one of five common autoimmune diseases, a new study found.

Previous research has linked both maternal and paternal autoimmune diseases and specific mental disorders, such as attention-deficit/hyperactivity disorder (ADHD), but most of these studies focused on specific conditions in relatively small populations. The new study included data on more than 2 million births, making it one of the largest efforts to date to examine the association, according to the researchers, whose findings were published in JAMA Network Open.

Previous evidence of the possible association between certain maternal autoimmune diseases and mental disorders in offspring has been “scattered and limited,” which “hampered an overall understanding” of the link, Fei Li, MD, the corresponding author of the study, told this news organization.

Dr. Li, of Shanghai Jiao Tong University China, and colleagues reviewed data from a Danish registry cohort of singleton births with up to 38 years of follow-up. They explored associations between a range of maternal autoimmune diseases diagnosed before childbirth and the risks of mental disorders in children in early childhood through young adulthood.

The study population included 2,254,234 births and 38,916,359 person-years. Data on mental health were collected from the Psychiatric Central Research Register and the country’s National Patient Register. The median age of the children at the time of assessment was 16.7 years; approximately half were male.

A total of 50,863 children (2.26%) were born to mothers who had been diagnosed with autoimmune diseases before childbirth. During the follow-up period, 5,460 children of mothers with autoimmune diseases and 303,092 children of mothers without autoimmune diseases were diagnosed with a mental disorder (10.73% vs. 13.76%), according to the researchers.

LISBON – A shift toward broader-spectrum antibiotics and increasing antibiotic resistance has led to high levels of mortality and neurodevelopmental impacts in surviving babies, according to a large international study conducted on four continents.

Results of the 3-year study were presented at this week’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID).

The observational study, NeoOBS, conducted by the Global Antibiotic Research and Development Partnership (GARDP) and key partners from 2018 to 2020, explored the outcomes of more than 3,200 newborns, finding an overall mortality of 11% in those with suspected neonatal sepsis. The mortality rate increased to 18% in newborns in whom a pathogen was detected in blood culture.

More than half of infection-related deaths (59%) were due to hospital-acquired infections. Klebsiella pneumoniae was the most common pathogen isolated and is usually associated with hospital-acquired infections, which are increasingly resistant to existing antibiotic treatments, said a report produced by GARDP to accompany the results.

The study also identified a worrying trend: Hospitals are frequently using last-line agents such as carbapenems because of the high degree of antibiotic resistance in their facilities. Of note, 15% of babies with neonatal sepsis were given last-line antibiotics.

Pediatrician Julia Bielicki, MD, PhD, senior lecturer, Paediatric Infectious Diseases Research Group, St. George’s University of London, and clinician at the University of Basel Children’s Hospital, Switzerland, was a coinvestigator on the NeoOBS study.

In an interview, she explained that, as well as reducing mortality, the research is about managing infections better to prevent long-term events and improve the quality of life for survivors of neonatal sepsis. “It can have life-changing impacts for so many babies,” Dr. Bielicki said. “Improving care is much more than just making sure the baby survives the episode of sepsis – it’s about ensuring these babies can become children and adults and go on to lead productive lives.”

Also, only a minority of patients (13%) received the World Health Organization guidelines for standard of care use of ampicillin and gentamicin, and there was increasing use of last-line agents such as carbapenems and even polymyxins in some settings in low- and middle-income countries. “This is alarming and foretells the impending crisis of a lack of antibiotics to treat sepsis caused by multidrug-resistant organisms,” according to the GARDP report.

There was wide variability in antibiotic combinations used across sites in Bangladesh, Brazil, China, Greece, India, Italy, Kenya, South Africa, Thailand, Uganda, and Vietnam, and often such use was not supported by underlying data.

Dr. Bielicki remarked that there was a shift toward broad-spectrum antibiotic use. “In a high-income country, you have more restrictive patterns of antibiotic use, but it isn’t necessarily less antibiotic exposure of neonates to antibiotics, but on the whole, usually narrow-spectrum agents are used.”

In Africa and Asia, on the other hand, clinicians often have to use a broader-spectrum antibiotic empirically and may need to switch to another antibiotic very quickly. “Sometimes alternatives are not available,” she pointed out.

“Local physicians are very perceptive of this problem of antibiotic resistance in their daily practice, especially in centers with high mortality,” said Dr. Bielicki, emphasizing that it is not their fault, but is “due to the limitations in terms of the weapons available to treat these babies, which strongly demonstrates the growing problem of antimicrobial resistance affecting these babies on a global scale.”

Tim Jinks, PhD, Head of Drug Resistant Infections Priority Program at Wellcome Trust, commented on the study in a series of text messages to this news organization. “This research provides further demonstration of the urgent need for improved treatment of newborns suffering with sepsis and particularly the requirement for new antibiotics that overcome the burden of drug-resistant infections caused by [antimicrobial resistance].”

“The study is a hugely important contribution to our understanding of the burden of neonatal sepsis in low- and middle- income countries,” he added, “and points toward ways that patient treatment can be improved to save more lives.”
 

High-, middle-, and low-income countries

The NeoOBS study gathered data from 19 hospitals in 11 high-, middle-, and low-income countries and assessed which antibiotics are currently being used to treat neonatal sepsis, as well as the degree of drug resistance associated with them. Sites included some in Italy and Greece, where most of the neonatal sepsis data currently originate, and this helped to anchor the data, Dr. Bielicki said.

The study identified babies with clinical sepsis over a 4-week period and observed how these patients were managed, particularly with respect to antibiotics, as well as outcomes including whether they recovered, remained in hospital, or died. Investigators obtained bacterial cultures from the patients and grew them to identify which organisms were causing the sepsis.

Of note, mortality varied widely between hospitals, ranging from 1% to 27%. Dr. Bielicki explained that the investigators were currently exploring the reasons behind this wide range of mortality. “There are lots of possible reasons for this, including structural factors such as how care is delivered, which is complex to measure,” she said. “It isn’t trivial to measure why, in a certain setting, mortality is low and why in another setting of comparable income range, mortality is much higher.”

Aside from the mortality results, Dr. Bielicki also emphasized that the survivors of neonatal sepsis frequently experience neurodevelopmental impacts. “A hospital may have low mortality, but many of these babies may have neurodevelopment problems, and this has a long-term impact.”

“Even though mortality might be low in a certain hospital, it might not be low in terms of morbidity,” she added.

The researchers also collected isolates from the cohort of neonates to determine which antibiotic combinations work against the pathogens. “This will help us define what sort of antibiotic regimen warrants further investigation,” Dr. Bielicki said.

Principal Investigator, Mike Sharland, MD, also from St. George’s, University of London, who is also the Antimicrobial Resistance Program Lead at Penta Child Health Research, said, in a press release, that the study had shown that antibiotic resistance is now one of the major threats to neonatal health globally. “There are virtually no studies underway on developing novel antibiotic treatments for babies with sepsis caused by multidrug-resistant infections.”

“This is a major problem for babies in all countries, both rich and poor,” he stressed.
 

NeoSep-1 trial to compare multiple different treatments

The results have paved the way for a major new global trial of multiple established and new antibiotics with the goal of reducing mortality from neonatal sepsis – the NeoSep1 trial.

“This is a randomized trial with a specific design that allows us to rank different treatments against each other in terms of effectiveness, safety, and costs,” Dr. Bielicki explained.

Among the antibiotics in the study are amikacin, flomoxef and amikacin, or fosfomycin and flomoxef in babies with sepsis 28 days old or younger. Similar to the NeoOBS study, patients will be recruited from all over the world, and in particular from low- and middle-income countries such as Kenya, South Africa, and other countries in Africa and Southeast Asia.

Ultimately, the researchers want to identify modifiable risk factors and enact change in practice. But Dr. Bielicki was quick to point out that it was difficult to disentangle those factors that can easily be changed. “Some can be changed in theory, but in practice it is actually difficult to change them. One modifiable risk factor that can be changed is probably infection control, so when resistant bacteria appear in a unit, we need to ensure that there is no or minimal transmission between babies.”

Luregn Schlapbach, MD, PhD, Head, department of intensive care and neonatology, University Children’s Hospital Zurich, Switzerland, welcomed the study, saying recent recognition of pediatric and neonatal sepsis was an urgent problem worldwide.

She referred to the 2017 WHO resolution recognizing that sepsis represents a leading cause of mortality and morbidity worldwide, affecting patients of all ages, across all continents and health care systems but that many were pediatric. “At that time, our understanding of the true burden of sepsis was limited, as was our knowledge of current epidemiology,” she said in an email interview. “The Global Burden of Disease study in 2020 revealed that about half of the approximatively 50 million global sepsis cases affect pediatric age groups, many of those during neonatal age.”

The formal acknowledgment of this extensive need emphasizes the “urgency to design preventive and therapeutic interventions to reduce this devastating burden,” Dr. Schlapbach said. “In this context, the work led by GARDP is of great importance – it is designed to improve our understanding of current practice, risk factors, and burden of neonatal sepsis across low- to middle-income settings and is essential to design adequately powered trials testing interventions such as antimicrobials to improve patient outcomes and reduce the further emergence of antimicrobial resistance.”

Dr. Bielicki and Dr. Schlapbach have disclosed no relevant financial relationships.

The latest upward trend in new COVID-19 cases among children picked up steam, but there was also some movement in the vaccination effort in the past week.

Moderna submitted a request to the Food and Drug administration for emergency use authorization of its COVID-19 vaccine in children under the age of 6 years, according to this news organization, and Pfizer/BioNTech officially applied for authorization of a booster dose in children aged 5-11, the companies announced.

The FDA has tentatively scheduled meetings of its Vaccines and Related Biological Products Advisory Committee in June to consider the applications, saying that it “understands the urgency to authorize a vaccine for age groups who are not currently eligible for vaccination and will work diligently to complete our evaluation of the data. Should any of the submissions be completed in a timely manner and the data support a clear path forward following our evaluation, the FDA will act quickly” to convene the necessary meetings.

The need for greater access to vaccines seems to be increasing, as new pediatric COVID cases rose for the third consecutive week. April 22-28 saw over 53,000 new cases reported in children, up 43.5% from the previous week and up 105% since cases started rising again after dipping under 26,000 during the week of April 1-7, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

Hospital admissions involving diagnosed COVID also ticked up over the latter half of April, although the most recent 7-day average (April 24-30) of 112 per day was lower than the 117 reported for the previous week (April 17-23), the Centers for Disease Control and Prevention said, also noting that figures for the latest week “should be interpreted with caution.”

Vaccinations also were up slightly in children aged 5-11 years, with 52,000 receiving their first dose during the week of April 21-27, compared with 48,000 the week before. There was a slight dip, however, among 12- to 17-year-olds, who received 34,000 first doses during April 21-27, versus 35,000 the previous week, the AAP said in a separate report.

Cumulatively, almost 69% of all children aged 12-17 years have received at least one dose of the COVID-19 vaccine and 59% are fully vaccinated. Those aged 5-11 are well short of those figures, with just over 35% having received at least one dose and 28.5% fully vaccinated, the CDC said on its COVID Data Tracker.

A look at recent activity shows that children are not gaining on adults, who are much more likely to be vaccinated – full vaccination in those aged 50-64, for example, is 80%. During the 2 weeks from April 17-30, the 5- to 11-year-olds represented 10.5% of those who had initiated a first dose and 12.4% of those who gained full-vaccination status, both of which were well below the oldest age groups, the CDC reported.

CHICAGO – Recent research has changed at least one physician’s understanding of obesity and boosted her hope for fighting it.

Caroline Apovian, MD, codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital, described some of the new insights about obesity she has gained during her talk at the annual meeting of the American College of Physicians.

“When I was a medical student a while back, I learned that fat tissue just sat there and stored fat,” she said. “Now we know it’s an endocrine organ.”

This tissue secretes hormones, such as leptin, and other factors that have an array of effects on the brain, pancreas, heart, liver, and muscles. Moreover, it has plasticity, with the ability to change, constantly adjusting our metabolism as nutrient supply and demand changes, she continued.

Obesity leads to a decline in this plasticity, leading to fibrosis and inflammation and other problems. These changes can further impair the function of adipose tissue, leading to metabolic disease. But the central role of adipose tissue, and its dynamic nature, presents an opportunity for treatment, Dr. Apovian said, during her talk.
 

Hints to why obesity has become more common

More than 42% of the U.S. population – “unbelievably,” Dr. Apovian said – is obese, meaning they have a BMI over 30, according to the Centers for Disease Control and Prevention. That’s up by about 25% since 1960, although calories eaten hasn’t increased, and physical activity has increased somewhat, she said.

The root cause is still a bit of a mystery, but according to “good hints and clues” from animal models that are starting to be translated to the study of human obesity, “it has to do with epigenetics and how our brains and our bodies are perceiving the environment,” she noted, during her presentation.

“Our genes haven’t changed. Our environment has changed,” she said.

The industrialization of the food supply, the use of pesticides and preservatives, the dawn of fast food have all combined, most likely, to do “a number on our bodies,” Dr. Apovian said.

But not all hope is lost thanks to new research, Dr. Apovian suggested.
 

New treatments show promise for helping patients’ obesity

New research that has increased Dr. Apovian’s understanding of the sophisticated role of adipose tissue may be helpful for treating patients with obesity, offering more targets for intervention, she told the audience.

Some treatment avenues already identified have started producing results, Dr. Apovian noted.

Gastric bypass surgery typically leads to a loss of 25% of body weight, but is often shunned by patients, she said. “With such a great surgical procedure, we still only do 256,000 procedures and we have millions of Americans with a BMI over 30.”

Weight control with obsessive dieting, meal-planning and calorie-counting, “can be done, but it’s really hard,” Dr. Apovian noted.

More appealing therapies targeting hormones and appetite suppression have produced impressive results. Recently approved semaglutide produced 14% weight loss, compared with about 2% for placebo, she said.

Results just released for tirzepatide, a dual agonist of gut hormones GLP-1 and GIP, show a 22% total weight loss, compared with about 2% for placebo, with about 56% of patients losing more than 20% of their body weight, Dr. Apovian said.

Referencing studies finding that several hormones are altered during weight loss, she predicted that targeting multiple hormones with drug treatment will also be necessary for best results.

But, she noted, “we’re treating obesity now with one- or two-drug combos.”
 

Medication costs are too high for many patients

Isis Smith, MD, an internist at University Medical Center in New Orleans, said in an interview that the cost of the most effective medications – which are not covered by Medicaid – means that many of her patients don’t have access to these treatments.

“We’re talking about $1,000 a month. And so there is no way they can afford [them]. I can prescribe phentermine [but] unless a patient has another indication, Medicaid will not pay for it,” she explained.

“I love hearing about all of the new developments. ... It’s interesting to hear, but we need to get insurance to pay so that I can actually prescribe,” Dr. Smith noted.

Dr. Apovian reports financial relationships with Xeno Biosciences, Cowen, Allergan, Novo Nordisk, Abbott Nutrition, and other companies.

The World Health Organization and United Nations International Children’s Emergency Fund are warning about a heightened risk of measles spreading and triggering larger outbreaks in 2022.

Worldwide cases are up nearly 80% so far over 2021, the groups reported. More than 17,300 measles cases were reported worldwide in January and February, compared with 9,600 cases at the beginning of 2021.

In the last 12 months, there have been 21 “large and disruptive” measles outbreaks, particularly in Africa and the East Mediterranean region. The actual numbers are likely higher because of underreporting and disruptions to surveillance systems.

“Pandemic-related disruptions, increasing inequalities in access to vaccines, and the diversion of resources from routine immunization are leaving too many children without protection against measles and other vaccine-preventable diseases,” the organizations said.

As cities and countries relax COVID-19 restrictions, measles outbreaks are becoming more likely, they noted.

“It is encouraging that people in many communities are beginning to feel protected enough from COVID-19 to return to more social activities. But doing so in places where children are not receiving routine vaccination creates the perfect storm for the spread of a disease like measles,” Catherine Russell, executive director for UNICEF, said in the statement.

In the past year, the largest measles outbreaks have occurred in Somalia, Yemen, Nigeria, Afghanistan, and Ethiopia. The main reason for outbreaks is a lack measles vaccine coverage, the organizations said.

About 23 million children missed childhood vaccinations in 2020, the groups said. Childhood vaccination campaigns were hindered because of the COVID-19 pandemic and conflicts in Ukraine, Ethiopia, Somalia, and Afghanistan.

Overall, 57 campaigns targeting vaccine-preventable diseases across 43 countries that were scheduled to take place since the beginning of the COVID-19 pandemic are still postponed, the groups said, which could affect 203 million people. Among those, 19 are measles campaigns, which could put 73 million children at risk of measles because of missed vaccinations.

Vaccine coverage of 95% or higher with two doses of the measles vaccine can provide protection, according to the organizations. But the five countries that had the highest measles cases in the last year had first-dose coverage between 46% and 68%.

In the United States, measles vaccinations in kindergarten students dropped from about 95% to 93.9% for the 2020-2021 school year, according to CNN.

Vaccination coverage also dropped from 95% to 93.6% for diphtheria, tetanus, acellular pertussis, and varicella. Even though the decreases appear small, it means tens of thousands of children across the United States started school without their common childhood vaccinations, the Centers for Disease Control and Prevention said.

“We are concerned that missed routine vaccinations could leave children vulnerable to preventable diseases like measles and whooping cough, which are extremely contagious and can be very serious, especially for babies and young children,” Shannon Stokley, DrPH, deputy director of the CDC’s immunization services division, told CNN.

The numbers show a “concerning decline in childhood immunizations that began in March 2020,” she said.

Health officials are investigating at least 30 cases of severe hepatitis in children across 10 U.S. states. The Minnesota Department of Health received two reports of severe hepatitis, one in an infant and another in a 2-year-old, the Associated Press reported on April 30. One child was treated “several months ago” and required a liver transplant, according to the article. 

Worldwide cases surpass 200, including 34 cases in the United Kingdom, the U.K. Health Security Agency announced on April 29. Most cases have occurred in the United Kingdom, but there have been more than 55 probable and confirmed hepatitis cases in children in 12 countries in the European Union or the European Economic Area. Cases have also been identified in Asia, with both Japan and Singapore reporting one case each of acute hepatitis, Bloomberg reported. Additionally, three children in Indonesia died from acute hepatitis in April, but the total number of cases in that country was not available.

Although the total number of worldwide cases remains small, the severity of the cases – as well as their unexplained cause – have health officials on alert, said David Lee Thomas, MD, MPH, of the Viral Hepatitis Center at Johns Hopkins Medicine in Baltimore. “There are some kids who would have died if not for liver transplants.”

In the United States, the only confirmed cases are in Alabama, where nine patients were admitted for severe hepatitis between October 2021 and February 2022. Beyond the two suspected cases in Minnesota, health officials are investigating at least 19 other potential cases in eight states, according to NBC News: Delaware (1), Georgia, Illinois (3), Louisiana (1), New York, North Carolina (2), Tennessee (6), and Wisconsin (4). (New York and Georgia did not specify the number of cases being investigated.)

Reported cases have occurred in patients aged between 1 month and 16 years old. Globally, at least 17 patients have needed liver transplants, according to a World Health Organization alert on April 23. While WHO officials said there has been at least one death globally linked to hepatitis, that does not include the three deaths in Indonesia. One death has also been reported in Wisconsin, but the state’s Department of Health Services did not confirm whether this death was included in the WHO announcement.

The cause of these severe hepatitis cases has yet to be identified, but these cases have tested negative for more common viruses that can cause hepatitis in children. There is no link between these cases and COVID-19 vaccination, according to WHO, because most affected children have not been vaccinated.

Adenovirus is a possible contributing factor in these cases, as many of the cases in Europe tested positive for the virus. In an analysis of the nine Alabama cases released by the Centers for Disease Control and Prevention, adenovirus was detected in the blood samples of all nine children. Five of the nine children tested positive for adenovirus type 41, which is a common cause of acute gastroenteritis in children. While the six liver biopsies performed showed varying degrees of hepatitis, there were “no viral inclusions observed, no immunohistochemical evidence of adenovirus, or no viral particles identified by electron microscopy,” according to the report. None of the children tested positive for COVID-19 or had a documented history of previous COVID-19 infection.

“At this time, we believe that adenovirus may be the cause for these reported cases, but other potential environmental and situational factors are still being investigated,” the CDC said in a media statement. The CDC added that the report was specific to the nine Alabama cases, and that the agency is working to investigate other potential cases with state and local public health officials.

While the “growing consensus” among experts is that adenovirus could be behind these severe cases, there are many unanswered questions, Dr. Thomas added, such as why this strain of adenovirus causes such severe hepatitis, and why the liver biopsies do not show classic signs of viral infection. That information will come as investigations continue.

“From a provider point of view, if you have a child with an unexplained liver problem, report it to the CDC,” he advised. “Right now, we have to learn more about [these cases],” and that requires more research like the investigations in Alabama, he noted.

Health officials are investigating at least 30 cases of severe hepatitis in children across 10 U.S. states. The Minnesota Department of Health received two reports of severe hepatitis, one in an infant and another in a 2-year-old, the Associated Press reported on April 30. One child was treated “several months ago” and required a liver transplant, according to the article. 

Worldwide cases surpass 200, including 34 cases in the United Kingdom, the U.K. Health Security Agency announced on April 29. Most cases have occurred in the United Kingdom, but there have been more than 55 probable and confirmed hepatitis cases in children in 12 countries in the European Union or the European Economic Area. Cases have also been identified in Asia, with both Japan and Singapore reporting one case each of acute hepatitis, Bloomberg reported. Additionally, three children in Indonesia died from acute hepatitis in April, but the total number of cases in that country was not available.

Although the total number of worldwide cases remains small, the severity of the cases – as well as their unexplained cause – have health officials on alert, said David Lee Thomas, MD, MPH, of the Viral Hepatitis Center at Johns Hopkins Medicine in Baltimore. “There are some kids who would have died if not for liver transplants.”

In the United States, the only confirmed cases are in Alabama, where nine patients were admitted for severe hepatitis between October 2021 and February 2022. Beyond the two suspected cases in Minnesota, health officials are investigating at least 19 other potential cases in eight states, according to NBC News: Delaware (1), Georgia, Illinois (3), Louisiana (1), New York, North Carolina (2), Tennessee (6), and Wisconsin (4). (New York and Georgia did not specify the number of cases being investigated.)

Reported cases have occurred in patients aged between 1 month and 16 years old. Globally, at least 17 patients have needed liver transplants, according to a World Health Organization alert on April 23. While WHO officials said there has been at least one death globally linked to hepatitis, that does not include the three deaths in Indonesia. One death has also been reported in Wisconsin, but the state’s Department of Health Services did not confirm whether this death was included in the WHO announcement.

The cause of these severe hepatitis cases has yet to be identified, but these cases have tested negative for more common viruses that can cause hepatitis in children. There is no link between these cases and COVID-19 vaccination, according to WHO, because most affected children have not been vaccinated.

Adenovirus is a possible contributing factor in these cases, as many of the cases in Europe tested positive for the virus. In an analysis of the nine Alabama cases released by the Centers for Disease Control and Prevention, adenovirus was detected in the blood samples of all nine children. Five of the nine children tested positive for adenovirus type 41, which is a common cause of acute gastroenteritis in children. While the six liver biopsies performed showed varying degrees of hepatitis, there were “no viral inclusions observed, no immunohistochemical evidence of adenovirus, or no viral particles identified by electron microscopy,” according to the report. None of the children tested positive for COVID-19 or had a documented history of previous COVID-19 infection.

The Sedentary Behavior Research Network has published new guidelines “to provide guidance to parents, educators, policy makers, researchers, and health care providers” on means to reduce school-related sedentary behavior.

The recommendations, published in the International Journal of Behavioral Nutrition and Physical Activity were written by researchers led by Travis J. Saunders, PhD, associate professor of applied human sciences at the University of Prince Edward Island, Charlottetown. Based on work carried out by a panel of international experts and informed by the best available evidence and stakeholder consultation, “these recommendations will be useful in supporting the physical and mental health, well-being, and academic success of school-age children and youth,” according to the authors.

The key strength of their work, they wrote, is that it is based on robust scientific data and specifically refers to school-related sedentary behaviors, whether these occur during lessons in the classroom or while completing assignments at home. “Existing sedentary behavior guidelines for children and youth target overall sedentary behavior and recreational screen time, without any specific recommendations regarding school-related sedentary behaviors.” The article also mentions the impact of the COVID-19 pandemic. Lack of movement was already a problem in these age groups; social distancing and distance learning over such an extended period only made things worse.
 

Risks and benefits

Dr. Saunders and colleagues wrote: “The relationships between sedentary behaviors and student health and academic outcomes are complex and likely differ for specific sedentary behaviors.”

While on one hand sedentary behavior may have a significant negative impact on metabolic outcomes, there is evidence that higher durations of homework and reading are associated with better academic achievement among school-aged children.

Another example of this complexity is that screen-based sedentary behaviors (spending time in front of computer screens, TVs, tablets, smartphones) often demonstrate deleterious associations with a range of health outcomes among school-aged children and youth aged 5-18 years, including body composition, cardiometabolic risk, and self-esteem. Yet screen-based devices may offer opportunities for novel pedagogic approaches and student engagement and may increase access to education for some students, especially during the COVID-19 pandemic.

The researchers noted that “many common sedentary activities ... do not have to be sedentary in nature. These behaviors are only considered to be sedentary when combined with both low energy expenditure and a sitting, reclining, or lying posture.” As an example, they pointed out that “active video gaming, or paper-based work at a standing desk, are both ways that common sedentary behaviors can be made nonsedentary.”

One thing’s for sure: Children and teenagers don’t move around all that much.

Data from the 2019 Eye on Health survey found that one of five children (20.3%) had not engaged in any physical activity the day before the survey, almost half (43.5%) had a TV in their bedroom, and about the same number (44.5%) spent more than 2 hours a day in front of a screen.

As for schools, the survey showed that, while 93% had initiatives to promote physical activity, fewer than 30% of these programs involved parents. It should be kept in mind that these are prepandemic numbers.
 

‘A healthy school day’

The authors recommend the following for reducing school-related sedentary behavior:

• Break up periods of extended sedentary behavior with both scheduled and unscheduled movement breaks: at least once every 30 minutes for ages 5-11 years and at least once every hour for ages 12-18 years. Consider activities that vary in intensity and duration (for example, standing, stretching breaks, moving to another classroom, active lessons, active breaks).
• Incorporate different types of movement into homework whenever possible, and limit sedentary homework to no more than 10 minutes per day per grade level (for example, no more than 10 minutes per day in grade 1, or 60 minutes per day in grade 6).
• Regardless of the location, school-related screen time should be meaningful, mentally or physically active, and serve a specific pedagogic purpose that enhances learning, compared with alternative methods. When school-related screen time is warranted, the following are recommended: limit time on devices, especially for students age 5-11 years; take a device break at least once every 30 minutes; discourage media multitasking in the classroom and while doing homework; and avoid screen-based homework within an hour of bedtime.
• Replace sedentary learning activities with movement-based learning activities (including standing) and replacing screen-based learning activities with non–screen-based learning activities (for example, outdoor lessons) can further support students’ health and well-being.

“Given the important role that schools can play in the promotion of healthy behaviors,” Dr. Saunders and associates wrote, “we encourage national and international public health agencies to consider inclusion of specific recommendations related to the school environment in future sedentary behavior guidelines.”

Rates of premature return to play (RTP) among student athletes following a sport-related concussion (SRC) have dropped substantially since 2011, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.

“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.

“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.

The study was published in Canadian Family Physician.
 

Differences by sex

The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.

Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.

There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).

Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.

The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
 

More concussions coming?

Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.

In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.

“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.

“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.

A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.
 

“Very positive shifts”

Commenting on the findings, Nick Reed, PhD, Canada research chair in pediatric concussion and associate professor of occupational science and occupational therapy, University of Toronto, said that sports medicine physicians are seeing “very positive shifts” in concussion awareness and related behaviors such as providing education, support, and accommodations to students within the school environment. “More and more teachers are seeking education to learn what a concussion is and what to do to best support their students with concussion,” he said. Dr. Reed was not involved in the current study.

Indeed, this increasing awareness led to the development of a concussion education tool for teachers – SCHOOLFirst – although Dr. Reed did acknowledge that not all teachers have either the knowledge or the resources they need to optimally support their students with concussion. In the meantime, to reduce the risk of injury, Dr. Reed stressed that it is important for students to wear equipment appropriate for the game being played and to play by the rules.

“It is key to play sports in a way that is fair and respectful and not [engage] in behaviors with the intent of injuring an opponent,” he stressed. It is also important for athletes themselves to know the signs and symptoms of concussion and, if they think they have a concussion, to immediately stop playing, report how they are feeling to a coach, teacher, or parent, and to seek medical assessment to determine if they have a concussion or not.

“The key here is to focus on what the athlete can do after a concussion rather than what they can’t do,” Dr. Reed said. After even a few days of complete rest, students with a concussion can gradually introduce low levels of physical and cognitive activity that won’t make their symptoms worse. This activity can include going back to school with temporary accommodations in place, such as shorter school days and increased rest breaks. “When returning to school and to sport after a concussion, it is important to follow a stepwise and gradual return to activities so that you aren’t doing too much too fast,” Dr. Reed emphasized.

The study was conducted without external funding. Dr. Carson and Dr. Reed reported no conflicts of interest.

Rates of premature return to play (RTP) among student athletes following a sport-related concussion (SRC) have dropped substantially since 2011, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.

“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.

“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.

The study was published in Canadian Family Physician.
 

Differences by sex

The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.

Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.

There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).

Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.

The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
 

More concussions coming?

Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.

In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.

“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.

“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.

A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.
 

“Very positive shifts”

Commenting on the findings, Nick Reed, PhD, Canada research chair in pediatric concussion and associate professor of occupational science and occupational therapy, University of Toronto, said that sports medicine physicians are seeing “very positive shifts” in concussion awareness and related behaviors such as providing education, support, and accommodations to students within the school environment. “More and more teachers are seeking education to learn what a concussion is and what to do to best support their students with concussion,” he said. Dr. Reed was not involved in the current study.

Indeed, this increasing awareness led to the development of a concussion education tool for teachers – SCHOOLFirst – although Dr. Reed did acknowledge that not all teachers have either the knowledge or the resources they need to optimally support their students with concussion. In the meantime, to reduce the risk of injury, Dr. Reed stressed that it is important for students to wear equipment appropriate for the game being played and to play by the rules.

“It is key to play sports in a way that is fair and respectful and not [engage] in behaviors with the intent of injuring an opponent,” he stressed. It is also important for athletes themselves to know the signs and symptoms of concussion and, if they think they have a concussion, to immediately stop playing, report how they are feeling to a coach, teacher, or parent, and to seek medical assessment to determine if they have a concussion or not.

“The key here is to focus on what the athlete can do after a concussion rather than what they can’t do,” Dr. Reed said. After even a few days of complete rest, students with a concussion can gradually introduce low levels of physical and cognitive activity that won’t make their symptoms worse. This activity can include going back to school with temporary accommodations in place, such as shorter school days and increased rest breaks. “When returning to school and to sport after a concussion, it is important to follow a stepwise and gradual return to activities so that you aren’t doing too much too fast,” Dr. Reed emphasized.

The study was conducted without external funding. Dr. Carson and Dr. Reed reported no conflicts of interest.
