Pediatrics

It’s back to school time, and some may be wondering what the current availability of vaccines may mean and the effects of the ever-changing COVID-19 guidelines on their children’s education and day-to-day experiences as students this year.

Unlike last school year, there are now vaccines available for all over the age of 6 months, and home rapid antigen tests are more readily available. Additionally, many have now been exposed either by infection or vaccination to the virus.

The CDC has removed the recommendations for maintaining cohorts in the K-12 population. This changing landscape along with differing levels of personal risk make it challenging to counsel families about what to expect in terms of COVID this year.

The best defense that we currently have against COVID is the vaccine. Although it seems that many are susceptible to the virus despite the vaccine, those who have been vaccinated are less susceptible to serious disease, including young children.

As older children may be heading to college, it is important

to encourage them to isolate when they have symptoms, even when they test negative for COVID as we would all like to avoid being sick in general.

Additionally, they should pay attention to the COVID risk level in their area and wear masks, particularly when indoors, as the levels increase. College students should have a plan for where they can isolate when not feeling well. If anyone does test positive for COVID, they should follow the most recent quarantine guidelines, including wearing a well fitted mask when they do begin returning to activities.
 

Monkeypox

We now have a new health concern for this school year.

Monkeypox has come onto the scene with information changing as rapidly as information previously did for COVID. With this virus, we must particularly counsel those heading away to college to be careful to limit their exposure to this disease.

Dormitories and other congregate settings are high-risk locations for the spread of monkeypox. Particularly, students headed to stay in dormitories should be counseled about avoiding:

• sexual activity with those with lesions consistent with monkeypox;
• sharing eating and drinking utensils; and
• sleeping in the same bed as or sharing bedding or towels with anyone with a diagnosis of or lesions consistent with monkeypox.

Additionally, as with prevention of all infections, it is important to frequently wash hands or use alcohol-based sanitizer before eating, and avoid touching the face after using the restroom.

Guidance for those eligible for vaccines against monkeypox seems to be quickly changing as well.

At the time of this article, CDC guidance recommends the vaccine against monkeypox for:

• those considered to be at high risk for it, including those identified by public health officials as a contact of someone with monkeypox;
• those who are aware that a sexual partner had a diagnosis of monkeypox within the past 2 weeks;
• those with multiple sex partners in the past 2 weeks in an area with known monkeypox; and
• those whose jobs may expose them to monkeypox.

Currently, the CDC recommends the vaccine JYNNEOS, a two-dose vaccine that reaches maximum protection after fourteen days. Ultimately, guidance is likely to continue to quickly change for both COVID-19 and Monkeypox throughout the fall. It is possible that new vaccinations will become available, and families and physicians alike will have many questions.

Primary care offices should ensure that someone is keeping up to date with the latest guidance to share with the office so that physicians may share accurate information with their patients.

Families should be counseled that we anticipate information about monkeypox, particularly related to vaccinations, to continue to change, as it has during all stages of the COVID pandemic.

As always, patients should be reminded to continue regular routine vaccinations, including the annual influenza vaccine.

The Food and Drug Administration has approved use of the Omnipod 5 automated insulin delivery system (Insulet Corp) for children aged 2 years and older with type 1 diabetes, the company announced on Aug. 22.

Omnipod 5 was originally cleared for use in individuals age 6 and older in Jan. 2022, as previously reported by this news organization. It is the third semi-automated closed-loop system approved in the United States but the first that is tubing-free. It integrates with the Dexcom G6 continuous glucose monitor system and a compatible smartphone to automatically adjust insulin and protect against high and low glucose levels.

“We received tremendous first-hand reports of how Omnipod 5 made diabetes management easier for our pivotal trial participants, and the clinical data demonstrated impressive glycemic improvements as well,” Trang Ly, MBBS, PhD, senior vice president and medical director at Insulet, said in a news release. “This expanded indication for younger children gives us great pride, knowing we can further ease the burden of glucose management for these children and their caregivers with our simple to use, elegant, automated insulin delivery system.”

In a recent clinical trial in very young children (age 2-5.9 years) with type 1 diabetes, Jennifer L. Sherr, MD, PhD, and colleagues found that the Omnipod 5 lowered A1c by 0.55 percentage points and reduced time in hypoglycemia (< 70 mg/dL) by 0.27%. According to their findings, published in Diabetes Care, time spent in target glucose range (70-180 mg/dL) increased by 11%, or by 2.6 hours more per day, in children in the study.

According to the release, the Omnipod 5 can now be prescribed to patients with insurance coverage. Patients can access their prescription through the pharmacy.

Researchers have identified 72 genes very strongly linked to autism spectrum disorders and more than 250 other genes with a strong link to ASD, according to a study published in Nature Genetics. The findings, based on analysis of more than 150,000 people’s genetics, arose from a collaboration of five research groups whose work included comparisons of ASD cohorts with separate cohorts of individuals with developmental delay or schizophrenia.

“We know that many genes, when mutated, contribute to autism,” and this study brought together “multiple types of mutations in a wide array of samples to get a much richer sense of the genes and genetic architecture involved in autism and other neurodevelopmental conditions,” co–senior author Joseph D. Buxbaum, PhD, director of the Seaver Autism Center for Research and Treatment at Mount Sinai and a professor at the Icahn School of Medicine at Mount Sinai, both in New York, said in a prepared statement. “This is significant in that we now have more insights as to the biology of the brain changes that underlie autism and more potential targets for treatment.”

Glen Elliott, PhD, MD, a clinical professor of psychiatry at Stanford (Calif.) University who was not involved in the study, said the paper is important paper for informing clinicians of where the basic research is headed. “We’re still in for a long road” before it bears fruit in terms of therapeutics. The value of studies like these, that investigate which genes are most associated with ASD, is that they may lead toward understanding the pathways in the brain that give rise to certain symptoms of ASD, which can then become therapeutic targets, Dr. Elliott said.
 

Investigating large cohorts

The researchers analyzed genetic exome sequencing data from 33 ASD cohorts with a total of 63,237 people and then compared these data with another cohort of people with developmental delay and a cohort of people with schizophrenia. The combined ASD cohorts included 15,036 individuals with ASD, 28,522 parents, and 5,492 unaffected siblings. The remaining participants were 5,591 people with ASD and 8,597 matched controls from case control studies.

In the ASD cohorts, the researchers identified 72 genes that were associated with ASD. De novo variants were eight times more likely in cases (4%) than in controls (0.5%). Ten genes occurred at least twice in ASD cases but never occurred in unaffected siblings.

Then the researchers integrated these ASD genetic data with a cohort of 91,605 people that included 31,058 people with developmental delay and their parents. Substantial overlap with gene mutations existed between these two cohorts: 70.1% of the genes related to developmental delay appeared linked to risk for ASD, and 86.6% of genes associated with ASD risk also had associations with developmental delay. Overall, the researchers identified 373 genes strongly associated with ASD and/or developmental delay and 664 genes with a likely association.

“Isolating genes that exert a greater effect on ASD than they do on other developmental delays has remained challenging due to the frequent comorbidity of these phenotypes,” wrote lead author Jack M. Fu, of Massachusetts General Hospital and Harvard Medical School, both in Boston, and colleagues. “Still, an estimated 13.4% of the transmission and de novo association–ASD genes show little evidence for association in the developmental delay cohort.”
 

ASD, developmental delay, and schizophrenia

When the researchers compared the cells where the genetic mutations occurred in fetal brains, they found that genes associated with developmental delay more often occurred in less differentiated cell types – less mature cells in the developmental process. Gene mutations associated with ASD, on the other hand, occurred in more mature cell types, particularly in maturing excitatory neurons and related cells.

”Our results are consistent with developmental delay-predominant genes being expressed earlier in development and in less differentiated cells than ASD-predominant genes,” they wrote.

The researchers also compared the specific gene mutations found in these two cohorts with a previously published set of 244 genes associated with schizophrenia. Of these, 234 genes are among those with a transmission and de novo association to ASD and/or developmental delay. Of the 72 genes linked to ASD, eight appear in the set of genes linked to schizophrenia, and 61 were associated with developmental delay, though these two subsets do not overlap each other much.

“The ASD-schizophrenia overlap was significantly enriched, while the developmental delay-schizophrenia overlap was not,” they reported. ”Together, these data suggest that one subset of ASD risk genes may overlap developmental delay while a different subset overlaps schizophrenia.”
 

Chasing therapy targets by backtracking through genes

The findings are a substantial step forward in understanding the potential genetic contribution to ASD, but they also highlight the challenges of eventually trying to use this information in a clinically meaningful way.

“Given the substantial overlap between the genes implicated in neurodevelopmental disorders writ large and those implicated directly in ASD, disentangling the relative impact of individual genes on neurodevelopment and phenotypic spectra is a daunting yet important challenge,” the researchers wrote. “To identify the key neurobiological features of ASD will likely require convergence of evidence from many ASD genes and studies.”

Dr. Elliott said the biggest takeaway from this study is a better understanding of how the paradigm has shifted away from finding “one gene” for autism or a cure based on genetics and more toward understanding the pathophysiology of symptoms that can point to therapies for better management of the condition.

“Basic researchers have completely changed the strategy for trying to understand the biology of major disorders,” including, in this case, autism, Dr. Elliott said. “The intent is to try to find the underlying systems [in the brain] by backtracking through genes. Meanwhile, given that scientists have made substantial progress in identifying genes that have specific effects on brain development, “the hope is that will mesh with this kind of research, to begin to identify systems that might ultimately be targets for treating.”

The end goal is to be able to offer targeted approaches, based on the pathways causing a symptom, which can be linked backward to a gene.

”So this is not going to offer an immediate cure – it’s probably not going to offer a cure at all – but it may actually lead to much more targeted medications than we currently have for specific types of symptoms within the autism spectrum,” Dr. Elliott said. “What they’re trying to do, ultimately, is to say, when this system is really badly affected because of a genetic abnormality, even though that genetic abnormality is very rare, it leads to these specific kinds of symptoms. If we can find out the neuroregulators underlying that change, then that would be the target, even if that gene were not present.”

The research was funded by the Simons Foundation for Autism Research Initiative, the SPARK project, the National Human Genome Research Institute Home, the National Institute of Mental Health, the National Institute of Child Health and Development, AMED, and the Beatrice and Samuel Seaver Foundation. Five authors reported financial disclosures linked to Desitin, Roche, BioMarin, BrigeBio Pharma, Illumina, Levo Therapeutics, and Microsoft.

“Basic researchers have completely changed the strategy for trying to understand the biology of major disorders,” including, in this case, autism, Dr. Elliott said. “The intent is to try to find the underlying systems [in the brain] by backtracking through genes. Meanwhile, given that scientists have made substantial progress in identifying genes that have specific effects on brain development, “the hope is that will mesh with this kind of research, to begin to identify systems that might ultimately be targets for treating.”

The end goal is to be able to offer targeted approaches, based on the pathways causing a symptom, which can be linked backward to a gene.

”So this is not going to offer an immediate cure – it’s probably not going to offer a cure at all – but it may actually lead to much more targeted medications than we currently have for specific types of symptoms within the autism spectrum,” Dr. Elliott said. “What they’re trying to do, ultimately, is to say, when this system is really badly affected because of a genetic abnormality, even though that genetic abnormality is very rare, it leads to these specific kinds of symptoms. If we can find out the neuroregulators underlying that change, then that would be the target, even if that gene were not present.”

The research was funded by the Simons Foundation for Autism Research Initiative, the SPARK project, the National Human Genome Research Institute Home, the National Institute of Mental Health, the National Institute of Child Health and Development, AMED, and the Beatrice and Samuel Seaver Foundation.

Pfizer has sent an application to the Food and Drug Administration for emergency use authorization of its updated COVID-19 booster vaccine for the fall of 2022, the company announced on Aug. 22.

The vaccine, which is adapted for the BA.4 and BA.5 Omicron variants, would be meant for ages 12 and older. If authorized by the FDA, the doses could ship as soon as September.

“Having rapidly scaled up production, we are positioned to immediately begin distribution of the bivalent Omicron BA.4/BA.5 boosters, if authorized, to help protect individuals and families as we prepare for potential fall and winter surges,” Albert Bourla, PhD, Pfizer’s chairman and CEO, said in the statement.

Earlier this year, the FDA ordered vaccine makers such as Pfizer and Moderna to update their shots to target BA.4 and BA.5, which are better at escaping immunity from earlier vaccines and previous infections.

The United States has a contract to buy 105 million of the Pfizer doses and 66 million of the Moderna doses, according to The Associated Press. Moderna is expected to file its FDA application soon as well.

The new shots target both the original spike protein on the coronavirus and the spike mutations carried by BA.4 and BA.5. For now, BA.5 is causing 89% of new infections in the United States, followed by BA.4.6 with 6.3% and BA.4 with 4.3%, according to the latest Centers for Disease Control and Prevention data.

There’s no way to tell if BA.5 will still be the dominant strain this winter or if new variant will replace it, the AP reported. But public health officials have supported the updated boosters as a way to target the most recent strains and increase immunity again.

On Aug. 15, Great Britain became the first country to authorize another one of Moderna’s updated vaccines, which adds protection against BA.1, or the original Omicron strain that became dominant in the winter of 2021-2022. European regulators are considering this shot, the AP reported, but the United States opted not to use this version since new Omicron variants have become dominant.

To approve the latest Pfizer shot, the FDA will rely on scientific testing of prior updates to the vaccine, rather than the newest boosters, to decide whether to fast-track the updated shots for fall, the AP reported. This method is like how flu vaccines are updated each year without large studies that take months.

Previously, Pfizer announced results from a study that found the earlier Omicron update significantly boosted antibodies capable of fighting the BA.1 variant and provided some protection against BA.4 and BA.5. The company’s latest FDA application contains that data and animal testing on the newest booster, the AP reported.

Pfizer will start a trial using the BA.4/BA.5 booster in coming weeks to get more data on how well the latest shot works. Moderna has begun a similar study.

The full results from these studies won’t be available before a fall booster campaign, which is why the FDA and public health officials have called for an updated shot to be ready for distribution in September.

“It’s clear that none of these vaccines are going to completely prevent infection,” Rachel Presti, MD, a researcher with the Moderna trial and an infectious diseases specialist at Washington University in St. Louis, told the AP.

But previous studies of variant booster candidates have shown that “you still get a broader immune response giving a variant booster than giving the same booster,” she said.

Two new studies offer insights into leukemia survival rates in the United States. From 2000 to 2014, a drop in mortality among children spurred a rise in 5-year leukemia survival rates among patients aged 0-24. But adolescents and young adults who survive 5 years after diagnosis face an ongoing higher risk of death, recent research revealed, and their long-term survival is lower compared to that of the general population.

“Outcomes are improving. However, additional efforts, support, and resources are needed to further improve short- and long-term survival for acute leukemia survivors. Targeted efforts focused on populations that face greater disparities in their survival are needed to move the needle faster,” Michael Roth, MD, codirector of the Adolescent and Young Adult Oncology Program at the University of Texas M.D. Anderson Cancer Center, said in an interview.

In one study, released in The Lancet Child & Adolescent Health, an international team of researchers tracked survival outcomes from various types of leukemia in 61 nations. The study focused on the years 2000-2014 and followed patients aged 0-24.

“Age-standardized 5-year net survival in children, adolescents, and young adults for all leukemias combined during 2010-14 varied widely, ranging from 46% in Mexico to more than 85% in Canada, Cyprus, Belgium, Denmark, Finland, and Australia,” the researchers wrote. “Throughout 2000-14, survival from all leukemias combined remained consistently higher for children than adolescents and young adults, and minimal improvement was seen for adolescents and young adults in most countries.”

The U.S. data came from 41 states that cover 86% of the nation’s population, lead author Naomi Ssenyonga, a research fellow at London School of Hygiene & Tropical Medicine, said in an interview.

The 5-year survival rate for acute lymphoid leukemia (ALL) rose from 80% during 2000-2004 to 86% during 2010-2014. Survival in patients with acute myeloid leukemia (AML) was lower than for other subtypes: 66% in 2010-2014 vs. 57% in 2000-2004.

In regard to all leukemias, “we noted a steady increase in the U.S. of 6 percentage points in 5-year survival, up from 77% for patients diagnosed during 2000-2004 to 83% for those diagnosed during 2010-2014,” Ms. Ssenyonga said. “The gains were largely driven by the improvements seen among children.”

Why haven’t adolescents and young adults gained as much ground in survival?

“They often have unique clinical needs,” Ms. Ssenyonga said. “Over the past few years, adolescents and young adults with leukemia in some parts of the world, including the U.S., have increasingly been treated under pediatric protocols. This has led to higher survival. However, this approach has not been adopted consistently, and survival for adolescents and young adults with leukemia is still generally lower than survival for children.”

Gwen Nichols, MD, chief medical officer of the Leukemia & Lymphoma Society, agreed that pediatric treatment protocols hold promise as treatments for young adults. However, “because we arbitrarily set an age cutoff for being an adult, many of these patients are treated by an adult [nonpediatric] hematologist/oncologist, and some patients in the 20-39 age group do not receive the more intensive treatment regimens given to children,” she said in an interview.

In another study, published in Cancer Epidemiology, Biomarkers, & Prevention, M.D. Anderson Cancer Center’s Dr. Roth and colleagues tracked 1,938 patients with ALL and 2,350 with AML who were diagnosed at ages 15-39 from 1980 to 2009. All lived at least 5 years after diagnosis. In both groups, about 58% were White, and most of the rest were Hispanic. The median age of diagnosis for ALL was 23 (range: 15-39) and 28 years for AML (range: 15-39).

“For ALL, 10-year survival for those diagnosed in the 1980s, 1990s, and 2000s was 83%, 88%, and 88%, respectively,” the researchers reported. “Ten-year survival for AML was 82%, 90%, and 90% for those diagnosed in the 1980s, 1990s, and 2000s, respectively.”

“Early mortality within 10 years of diagnosis was mostly secondary to leukemia progressing or recurring. We believe that later mortality is secondary to the development of late side effects from their cancer treatment,” Dr. Roth said.

He noted that many adolescents and young adults with ALL or AML receive stem-cell transplants. “This treatment approach is effective. However, it is associated with short- and long-term toxicity that impacts patients’ health for many years after treatment.”

Indeed, up to 80% of acute leukemia survivors have significant health complications after therapy, said the Leukemia & Lymphoma Society’s Dr. Nichols, who wasn’t surprised by the findings. According to the society, “even when treatments are effective, more than 70% of childhood cancer survivors have a chronic health condition and 42% have a severe, disabling or life-threatening condition 30 years after diagnosis.”

“It would be interesting to understand the male predominance better,” she added, noting that the study found that male patients had worse long-term survival than females (survival time ratio: 0.61, 95% confidence interval, 0.45-0.82). “While it is tempting to suggest it is due to difference in cardiac disease, I am not aware of data to support why there is this survival difference.”

What’s next? “In ALL, we now have a number of new modalities to treat high-risk and relapsed disease such as antibodies and CAR-T,” Dr. Nichols said. “We anticipate that 5-year survival can improve utilizing these modalities due to getting more patients into remission, hopefully while reducing chemotherapeutic toxicity.”

Dr. Nichol’s also highlighted the society’s new genomic-led Pediatric Acute Leukemia (PedAL) Master Clinical Trial, which began enrolling children with acute leukemia in the United States and Canada this year, in an effort to transform medicine’s traditional high-level chemotherapy strategy to their care. The project was launched in collaboration with the National Cancer Institute, Children’s Oncology Group, and the European Pediatric Acute Leukemia Foundation.

As part of the screening process, the biology of each child’s cancer will be identified, and families will be encouraged to enroll them in appropriate targeted therapy trials.

“Until we are able to decrease the toxicity of leukemia regimens, we won’t see a dramatic shift in late effects and thus in morbidity and mortality,” Dr. Nichols said. “The trial is an effort to test newer, less toxic regimens to begin to change that cycle.”

The 5-year survival study was funded by Children with Cancer UK, Institut National du Cancer, La Ligue Contre le Cancer, Centers for Disease Control and Prevention, Swiss Re, Swiss Cancer Research foundation, Swiss Cancer League, Rossy Family Foundation, National Cancer Institute, and the American Cancer Society. One author reports a grant from Macmillan Cancer Support, consultancy fees from Pfizer, and unsolicited small gifts from Moondance Cancer Initiative for philanthropic work. The other authors report no disclosures.

The long-term survival study was funded by the National Cancer Institute, the Archer Foundation and LyondellBasell Industries. Dr. Roth reports no disclosures; other authors report various disclosures. Dr. Nichols reports no disclosures.

The 7-day average percentage of ED visits with diagnosed COVID, which had reached a post-Omicron high of 3.5% in late July for those aged 12-15, began to fall and was down to 3.0% on Aug. 12. That trend reversed, however, and the rate was up to 3.6% on Aug. 19, the last date for which data are available from the Centers for Disease Control and Prevention.

That change of COVID fortunes cannot yet be seen for all children. The 7-day average ED visit rate for those aged 0-11 years peaked at 6.8% during the last week of July and has continued to fall, dropping from 5.7% on Aug. 12 to 5.1% on Aug. 19. Children aged 16-17 years seem to be taking a middle path: Their ED-visit rate declined from late July into mid-August but held steady over the last week, according to the CDC’s COVID Data Tracker.

There is a hint of the same trend regarding new admissions among children aged 0-17 years. The national rate, which had declined in recent weeks, ticked up from 0.42 to 0.43 new admissions per 100,000 population over the last week of available data, the CDC said.
 

Weekly cases fall below 80,000

New cases in general were down by 8.5% from the previous week, dropping from 87,902 for the week of Aug. 5-11 to 79,525 for Aug. 12-18. That marked the second straight week with fewer cases after a 4-week period that saw weekly totals increase from almost 68,000 to nearly 97,000, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

The AAP and CHA put the cumulative number of child COVID-19 cases at just under 14.4 million since the pandemic began, which represents 18.4% of cases among all ages. The CDC estimates that there have been almost 14.7 million cases in children aged 0-17 years, as well as 1,750 deaths, of which 14 were reported in the last week (Aug. 16-22).

The CDC age subgroups indicate that children aged 0-4 years have experienced fewer cases (2.9 million) than children aged 5-11 years (5.6 million cases) and 12-15 (3.0 million cases) but more deaths: 548 so far, versus 432 for 5- to 11-year-olds and 437 for 12- to 15-year-olds, the COVID Data Tracker shows. Those aged 0-4 make up 6% of the total U.S. population, compared with 8.7% and 5.1%, respectively, for the older children.

Most younger children still not vaccinated

Although it may not qualify as a big push to vaccinate children before the start of the new school year, first-time vaccinations did rise somewhat in late July and August for children aged 5-17 years. Among children younger than 5 years, though, initial doses of the vaccine fell during the second full week of August, especially in 2- to 4-year-olds, based on the CDC data.

Through almost 2 months of vaccine eligibility, 4.8% of children under age 5 have received at least one dose and 0.9% are fully vaccinated as of Aug. 17. The current rates are 37.8% (one dose) and 30.4% (completed) for those aged 5-11 and 70.5% and 60.3% for 12- to 17-year-olds.

Children who do not get enough sleep for one night can be cranky, groggy, or meltdown prone the next day.

Over time, though, insufficient sleep may impair neurodevelopment in ways that can be measured on brain scans and tests long term, a new study shows.

Research published in The Lancet Child & Adolescent Health found that 9- and 10-year-olds who do not get at least 9 hours of sleep most nights tend to have less gray matter and smaller areas of the brain responsible for attention, memory, and inhibition control, relative to children who do get enough sleep.

The researchers also found a relationship between insufficient sleep and disrupted connections between the basal ganglia and cortical regions of the brain. These disruptions appeared to be linked to depression, thought problems, and impairments in crystallized intelligence, a type of intelligence that depends on memory.

The overall patterns persisted 2 years later, even as those who got enough sleep at baseline gradually slept less over time, while those who were not getting enough sleep to begin with continued to sleep about the same amount, the researchers reported.

The results bolster the case for delaying school start times, as California recently did, according one researcher who was not involved in the study.
 

The ABCD Study

To examine how insufficient sleep affects children’s mental health, cognition, brain function, and brain structure over 2 years, Ze Wang, PhD, professor of diagnostic radiology and nuclear medicine at the University of Maryland, Baltimore, and colleagues analyzed data from the ongoing Adolescent Brain Cognitive Development (ABCD) Study. The ABCD Study is tracking the biologic and behavioral development of more than 11,000 children in the United States who were recruited for the study when they were 9 or 10 years old.

For their new analysis, Dr. Wang’s group focused on 6,042 participants: 3,021 children with insufficient sleep who were matched with an equal number of participants who were similar in many respects, including sex, socioeconomic status, and puberty status, except they got at least 9 hours of sleep. They also looked at outcomes 2 years later from 749 of the matched pairs who had results available.

The investigators determined sleep duration based on how parents answered the question: “How many hours of sleep does your child get on most nights in the past 6 months?” Possible answers included at least 9 hours, 8-9 hours, 7-8 hours, 5-7 hours, or less than 5 hours. They also looked at functional and structural MRI scans, test results, and responses to questionnaires.

Negative effects of inadequate sleep were spread over “several different domains including brain structure, function, cognition, behavior, and mental health,” Dr. Wang said.

The strength of the relationship between sleep duration and the various outcomes was “modest” and based on group averages, he said. So, a given child who does not sleep for 9 hours most nights won’t necessarily perform worse than a child who gets enough sleep.

Still, modest effects may accumulate and have lasting consequences, Dr. Wang said.
 

Crystallized intelligence

The researchers looked at 42 behavioral outcomes, 32 of which were significantly different between the groups. Four outcomes in particular – depression, thought problems, performance on a picture-vocabulary test, and crystallized intelligence – were areas where insufficient sleep seemed to have a larger negative effect.

Sleep duration’s relationship with crystallized intelligence was twice that for fluid intelligence, which does not depend on memory.

“Sleep affects memory,” Dr. Wang said. “Crystallized intelligence depends on learned skills and knowledge, which are memory. In this sense, sleep is related to crystallized intelligence.”

One limitation of the study is that some parents may not accurately report how much sleep their child gets, Dr. Wang acknowledged. Children may be awake when parents think they are asleep, for example.

And although the results show getting 9 hours of sleep may help neurocognitive development, it’s also possible that excessive amounts of sleep could be problematic, the study authors wrote.

Further experiments are needed to prove that insufficient sleep – and not some other, unaccounted for factor – causes the observed impairments in neurodevelopment.

To promote healthy sleep, parents should keep a strict routine for their children, such as a regular bedtime and no electronic devices in the bedroom, Dr. Wang suggested. More physical activity during the day also should help.

If children have high levels of stress and depression, “finding the source is critical,” he said. Likewise, clinicians should consider how mental health can affect their patients’ sleep.
 

More to healthy sleep than duration

“This study both aligns with and advances existing research on the importance of sufficient sleep for child well-being,” said Ariel A. Williamson, PhD, DBSM, a psychologist and pediatric sleep expert in the department of child and adolescent psychiatry and behavioral sciences at Children’s Hospital of Philadelphia and assistant professor of psychiatry and pediatrics at University of Pennsylvania, also in Philadelphia.

The researchers used rigorous propensity score matching, longitudinal data, and brain imaging, which are “innovative methods that provide more evidence on potential mechanisms linking insufficient sleep and child outcomes,” said Dr. Williamson, who was not involved in the study.

While the investigators focused on sleep duration, child sleep health is multidimensional and includes other elements like timing and perception of sleep quality, Dr. Williamson noted. “For example, some research shows that having a sleep schedule that varies night to night is linked to poor child outcomes.”

Dr. Williamson tells families and clinicians that “sleep is a pillar of health,” equal to diet and exercise. That said, sleep recommendations need to fit within a family’s life – taking into account after school activities and late-night homework sessions. But extending sleep by just “20-30 minutes can make a meaningful difference for daytime functioning,” Dr. Williamson said.
 

Start school later?

Researchers have only relatively recently begun to understand how insufficient sleep affects adolescent neurocognitive development long term, and this study provides “crucial evidence” about the consequences, Lydia Gabriela Speyer, PhD, said in an editorial published with the study. Dr. Speyer is affiliated with the department of psychology at the University of Cambridge (England).

“Given the novel finding that insufficient sleep is associated with changes in brain structure and connectivity that are long-lasting, early intervention is crucial because such neural changes are probably not reversible and might consequently affect adolescents’ development into adulthood,” Dr. Speyer wrote.

Delaying school start times could be one way to help kids get more sleep. The American Academy of Pediatrics and the American Academy of Sleep Medicine recommend that middle schools and high schools start no earlier than 8:30 a.m. to better align with students’ circadian rhythm, Dr. Speyer noted.

As it is in the United States, most schools start closer to 8 a.m. In California, though, a law that went into effect on July 1 prohibits high schools from starting before 8:30 a.m. Other states are weighing similar legislation.

The research was supported by the National Institutes of Health. Dr. Wang and his coauthors and Dr. Speyer had no conflict of interest disclosures. Dr. Williamson is a sleep expert for the Pediatric Sleep Council (www.babysleep.com), which provides free information about early childhood sleep, but she does not receive compensation for this role.

Children born near fracking and other “unconventional” drilling sites are at two to three times greater risk of developing childhood leukemia, according to new research.

The study, published in the journal Environmental Health Perspectives, compared proximity of homes to unconventional oil and gas development (UOGD) sites and risk of the most common form of childhood leukemia, acute lymphoblastic leukemia (ALL).

Researchers looked at 405 children aged 2-7 diagnosed with ALL in Pennsylvania from 2009 to 2017. These children were compared to a control group of 2,080 without the disease matched on the year of birth.

“Unconventional oil and gas development can both use and release chemicals that have been linked to cancer,” study coauthor Nicole Deziel, PhD, of the Yale School of Public Health, New Haven, Conn., said in a  statement . She noted that the possibility that children living in close proximity to such sites are “exposed to these chemical carcinogens is a major public health concern.”

About 17 million Americans live within a half-mile of active oil and gas production, according to the Oil & Gas Threat Map, Common Dreams reports. That number includes 4 million children.

The Yale study also found that drinking water could be an important pathway of exposure to oil- and gas-related chemicals used in the UOGD methods of extraction.

Researchers used a new metric that measures exposure to contaminated drinking water and distance to a well. They were able to identify UOGD-affected wells that fell within watersheds where children and their families likely obtained their water.

“Previous health studies have found links between proximity to oil and gas drilling and various children’s health outcomes,” said Dr. Deziel. “This study is among the few to focus on drinking water specifically and the first to apply a novel metric designed to capture potential exposure through this pathway.”

Researchers looked at 405 children aged 2-7 diagnosed with ALL in Pennsylvania from 2009 to 2017. These children were compared to a control group of 2,080 without the disease matched on the year of birth.

“Unconventional oil and gas development can both use and release chemicals that have been linked to cancer,” study coauthor Nicole Deziel, PhD, of the Yale School of Public Health, New Haven, Conn., said in a  statement . She noted that the possibility that children living in close proximity to such sites are “exposed to these chemical carcinogens is a major public health concern.”

About 17 million Americans live within a half-mile of active oil and gas production, according to the Oil & Gas Threat Map, Common Dreams reports. That number includes 4 million children.

The Yale study also found that drinking water could be an important pathway of exposure to oil- and gas-related chemicals used in the UOGD methods of extraction.

Researchers used a new metric that measures exposure to contaminated drinking water and distance to a well. They were able to identify UOGD-affected wells that fell within watersheds where children and their families likely obtained their water.

“Previous health studies have found links between proximity to oil and gas drilling and various children’s health outcomes,” said Dr. Deziel. “This study is among the few to focus on drinking water specifically and the first to apply a novel metric designed to capture potential exposure through this pathway.”

Health charities called for action to address racial health disparities after population-wide analysis by the UK Health Security Agency found that Black and Asian neonates had a significantly higher risk of early-onset group B streptococcal disease (GBS), compared with White infants.

One support group said more research was now needed to identify the cause of the disparity, and called for pregnant women to be better informed about the disease and what it could mean for them and their baby.

The study, published in Pediatrics, used UKHSA data on laboratory-confirmed infant group B streptococcal (iGBS) disease cases between Jan. 1, 2016, and Dec. 31, 2020, and were linked to hospital ethnicity records.

Cases of iGBS were defined as isolation of Streptococcus agalactiae from a normally sterile site at 0-6 days of life for early-onset iGBS and 7-90 days for late-onset disease.
 

Hospital data and parent-reported ethnicity

Researchers found 2,512 iGBS cases in England during the study period, 65.3% were early onset and 34.8% late onset, equivalent to 0.52 and 0.28 cases per 1000 live births respectively.

Researchers were able to link 85.6% of those to ethnicity. Among those 2,149 cases, Black infants had a 48% higher risk, and Asian infants a 40% higher risk of early onset iGBS, compared with White infants. Among those from an Asian background, the risk was 87% higher for Bangladeshi and 38% higher for Pakistani neonates.

Rates of early onset iGBS per 1,000 live births were 0.43 for White infants, 0.63 for Black infants, and 0.60 for those of Asian ethnicity.

In contrast, Indian infants had an early-onset rate of 0.47 per 1,000 live births, which was similar to White infants.

Black infants had 57% higher rates of late-onset iGBS (0.37) than White infants (0.24), the researchers reported.

The study authors highlighted previous research which found higher prevalence of group B streptococcal colonization in mothers from Black and some Asian ethnic groups, but lower prevalence in mothers from the Indian subcontinent. More research was needed to establish causes, the researchers said, including whether higher preterm birth rates in minority ethnic groups led to increased iGBS risk in neonates, or whether maternal group B streptococcal disease led to higher preterm birth rates and subsequent neonatal iGBS.

The researchers concluded: “Understanding the factors underpinning differences in rates of early-onset iGBS within south Asian groups in England may lead to new opportunities for prevention such as prioritized antenatal screening. Strategies to prevent neonatal iGBS must be tailored from high-quality quantitative and qualitative data to reach all women and protect all infants, irrespective of racial or ethnic background.”
 

‘Shocking but not surprising’

Commenting on the study, Edward Morris, president of the Royal College of Obstetricians and Gynaecologists, said: “This research is striking reading, and is yet another example of how far we have to go to tackle health inequalities within women’s health care.”

Philip Steer, professor emeritus at Imperial College London, said that the results were “consistent with previous reports of higher GBS carriage and higher maternal and neonatal mortality rates in minority groups” and “emphasize the importance of studying not just whether, but why, these differences exist.” He added: “We need to understand the reasons for the differences before we can design much-needed intervention to eliminate them.”

Jane Plumb, chief executive of Group B Strep Support, called the findings “shocking, but unfortunately not surprising” and said that they offered “another example of racial disparities in maternal and neonatal health.” She said: “We’re calling for all pregnant women and birthing people to be informed about GBS and its risks, so they can make empowered choices for themselves and their baby. It is also critical that trusts sign up to take part in the internationally significant [National Institute for Health and Care Research]–funded GBS3 clinical trial, designed to improve the prevention of GBS infection.”

Baroness Shaista Gohir, chief executive of the Muslim Women’s Network, said: “With significantly higher rates of group B Strep infection in Black and Asian babies, greater efforts must be made to improve awareness among pregnant women within these communities.”

Siblings of children with chronic health conditions could be at an increased risk for depression, according to a new report.

In a systematic review of 34 studies, siblings of children with chronic health conditions had significantly higher scores on depressive rating scales than individuals without a sibling with a chronic health condition (standardized mean difference = 0.53; P < .001). Findings related to other clinical health outcomes, such as physical health conditions or mortality, were inconsistent.

“We’ve known for a long time that siblings of kids with chronic conditions undergo stress, and there have been conflicting data on how that stress is manifested in terms of their own health,” senior study author Eyal Cohen, MD, program head for child health evaluative sciences at the Hospital for Sick Children, Toronto, told this news organization.

“For some siblings, having the experience of being raised with a child with a chronic condition may be an asset and build resiliency, while other siblings may feel strong negative emotions, such as sadness, anger, and fear,” he said. “Although we know that this experience is stressful for many siblings, it is important to know whether it changes their health outcomes, so that appropriate support can be put in place for those who need it.”

The study was published online in the Journal of Pediatrics.
 

Risk for psychological challenges

About a quarter of children in the United States have a mental, emotional, developmental, or behavioral condition, and more than a third have at least one current or lifelong health condition, the study authors write. A childhood chronic health condition can affect family members through worse mental health outcomes, increased stress, and poorer health-related quality of life.

Dr. Cohen and colleagues conducted a systematic review and meta-analysis to assess the clinical mental and physical health outcomes of siblings of children with chronic health conditions in comparison with siblings of healthy children or normative data.

The research team included English-language studies that reported on clinically diagnosable mental or physical health outcomes among siblings of persons younger than 18 years who had a chronic health condition. They included a comparison group and used an experimental or observational design for their study. The researchers analyzed 34 studies, including 28 that reported on mental health, 3 that reported on physical health, and 3 that reported on mortality.

Overall, siblings of children with chronic health conditions had significantly higher scores on depression rating scales than their comparison groups. Siblings’ anxiety scores weren’t substantially higher, however (standard mean difference = 0.21; P = .07).

The effects for confirmed psychiatric diagnoses, physical health outcomes, and mortality could not be included in the meta-analysis, owing to the limited number of studies and the high level of heterogeneity among the studies.

Dr. Cohen noted that although the researchers weren’t surprised that siblings may be at increased risk of mental health challenges, they were surprised by the limited data regarding physical health.

“At a minimum, our findings support the importance of asking open-ended questions about how a family is doing during clinical encounters,” he said. “These siblings may also benefit from programs such as support groups or summer camps, which have been shown to improve mental health and behavioral outcomes in siblings of children with chronic health conditions, such as cancer and neurodevelopmental disabilities.”

Future studies should assess the specific risk factors for mental health problems in siblings of children with chronic health conditions, Dr. Cohen said. Additional research could also investigate the design and effectiveness of interventions that address these concerns.
 

Message of inclusiveness

“The message that resonates with me is about the interventions and resources needed to support siblings,” Linda Nguyen, a doctoral student in rehabilitation science and researcher with the CanChild Center for Childhood Disability Research at McMaster University in Hamilton, Ont., told this news organization.

Ms. Nguyen, who wasn’t involved with this study, has researched the resources available to siblings in Canada and has found a lack of support options, particularly when it comes to specific health care management roles.

“Consistently throughout my research, I’ve seen the need for resources that go beyond a focus on siblings’ well-being and instead support them in their different roles,” she said. “Some want to be friends, mentors, supporters, and caregivers for their siblings in the future.”

Siblings often adopt different roles as they form their own identity, Ms. Nguyen noted, which becomes a larger part of the health care conversation as children with chronic conditions make the transition from pediatric to adult health care. Siblings want to be asked how they’d like to be involved, she said. Some would like to be involved with health care appointments, the chronic condition community, research, and policy making.

“At the societal level and public level, there’s also a message of inclusiveness and making sure that we’re welcoming youth with disabilities and chronic conditions,” Jan Willem Gorter, MD, PhD, a professor of pediatrics and scientist for CanChild at McMaster University, told this news organization.

Dr. Gorter, who also was not involved with this study, noted that children with chronic conditions often feel left behind, which can influence the involvement of their siblings as well.

“There are a lot of places in the world where children with disabilities go to special schools, and they spend a lot of time in a different world, with different experiences than their siblings,” he said. “At the public health level, we want to advocate for an inclusive society and support the whole family, which benefits everybody.”

The study was funded by the Canadian Institutes of Health Research and the CHILD-BRIGHT Network summer studentship, which is supported by the Canadian Institute for Health Research Strategy for Patient-Oriented Research. Dr. Cohen, Ms. Nguyen, and Dr. Gorter have disclosed no relevant financial relationships.
