Why 9 is not too young for the HPV vaccine
For Sonja O’Leary, MD, higher rates of vaccination against human papillomavirus came with the flip of a switch.
Dr. O’Leary, the interim director of service for outpatient pediatric services at Denver Health and Hospital Authority, and her colleagues saw rates of HPV and other childhood immunizations drop during the COVID-19 pandemic and decided to act. Their health system, which includes 28 federally qualified health centers, offers vaccines at any inpatient or outpatient visit based on alerts from their electronic health record.
“It was actually really simple; it was really just changing our best-practice alert,” Dr. O’Leary said. Beginning in May 2021, and after notifying clinic staff of the impending change, DHHA dropped the alert for first dose of HPV from age 11 to 9.
The approach worked. Compared with the first 5 months of 2021, the percentage of children aged 9-13 years with an in-person visit who received at least one dose of HPV vaccine between June 2021 and August 2022 rose from 30.3% to 42.8% – a 41% increase. The share who received two doses by age 13 years more than doubled, from 19.3% to 42.7%, Dr. O’Leary said.
Frustrated efforts
Although those figures might seem to make an iron-clad case for earlier vaccinations against HPV – which is responsible for nearly 35,000 cases of cancer annually – factors beyond statistics have frustrated efforts to increase acceptance of the shots.
Data published in 2022 from the U.S. Centers for Disease Control and Prevention found that 89.6% of teens aged 13-17 years received at least one dose of tetanus, diphtheria, and acellular pertussis vaccine, and 89% got one or more doses of meningococcal conjugate vaccine. However, only 76.9% had received one or more doses of HPV vaccine. The rate of receiving both doses needed for full protection was much lower (61.7%).
Both the American Academy of Pediatrics and the American Cancer Society now endorse the strategy of offering HPV vaccine as early as age 9, which avoids the need for multiple shots at a single visit and results in more kids getting both doses. In a recent study that surveyed primary care professionals who see pediatric patients, 21% were already offering HPV vaccine at age 9, and another 48% were willing to try the approach.
What was the most common objection to the earlier age? Nearly three-quarters of clinicians said they felt that parents weren’t ready to talk about HPV vaccination yet.
Noel Brewer, PhD, one of the authors of the survey study, wondered why clinicians feel the need to bring up sex at all. “Providers should never be talking about sex when they are talking about vaccine, because that’s not the point,” said Dr. Brewer, the distinguished professor in public health at the University of North Carolina at Chapel Hill. He pointed out that providers don’t talk about the route of transmission for any other vaccine.
Dr. Brewer led a randomized controlled trial that trained pediatric clinicians in the “announcement” strategy, in which the clinician announces the vaccines that are due at that visit. If the parent hesitates, the clinician then probes further to identify and address their concerns and provides more information. If the parent is still not convinced, the clinician notes the discussion in the chart and tries again at the next visit.
The strategy was effective: Intervention clinics had a 5.4% higher rate of HPV vaccination coverage than control clinics after six months. Dr. Brewer and his colleagues have trained over 1,700 providers in the technique since 2020.
A cancer – not STI – vaccine
Although DHHA hasn’t participated in Dr. Brewer’s training, Dr. O’Leary and her colleagues take a similar approach of simply stating which vaccines the child should receive that day. And they talk about HPV as a cancer vaccine instead of one to prevent a sexually transmitted infection.
In her experience, this emphasis changes the conversation. Dr. O’Leary described a typical comment from parents as, “Oh, of course I would give my child a vaccine that could prevent cancer.”
Ana Rodriguez, MD, MPH, an obstetrician, became interested in raising rates of vaccination against HPV after watching too many women battle a preventable cancer. She worked for several years in the Rio Grande Valley along the U.S. border with Mexico, an impoverished rural area with poor access to health care and high rates of HPV infection.
“I would treat women very young – not even 30 years of age – already fighting advanced precancerous lesions secondary to HPV,” said Dr. Rodriguez, an associate professor of Obstetrics & Gynecology at the University of Texas Medical Branch at Galveston.
In 2016, when Texas ranked 47th in the nation for rates of up-to-date HPV vaccination, Dr. Rodriguez helped launch a community-based educational campaign in four rural counties in the Rio Grande Valley using social media, radio, and in-person meetings with school PTA members and members of school boards to educate staff and parents about the need for vaccination against the infection.
In 2019, the team began offering the vaccine to children ages 9-12 years at back-to-school events, progress report nights, and other school events, pivoting to outdoor events using a mobile vaccine van after COVID-19 struck. They recently published a study showing that 73.6% of students who received their first dose of vaccine at age 11 or younger completed the series, compared with only 45.1% of children who got their first dose at age 12 or older.
Dr. Rodriguez encountered parents who felt 9 or 10 years old was too young because their children were not going to be sexually active anytime soon. Her response was to describe HPV as a tool to prevent cancer, telling parents, “If you vaccinate your kids young enough, they will be protected for life.”
Lifetime protection is another point in favor of giving HPV vaccine prior to Tdap and MenACWY. The response to the two-dose series of HPV in preadolescents is robust and long-lasting, with no downside to giving it a few years earlier. In contrast, immunity to MenACWY wanes after a few years, so the immunization must be given before children enter high school, when their risk for meningitis increases.
The annual toll of deaths in the United States from meningococcus, tetanus, diphtheria, and pertussis typically totals less than 100, whereas cancer deaths attributable to HPV infection number in the thousands each year. And that may be the best reason for attempting new strategies to help HPV vaccination rates catch up to the rest of the preteen vaccines.
Dr. Brewer’s work was supported by the Gillings School of Global Public Health, the Lineberger Comprehensive Cancer Center at the University of North Carolina, and from training grants from the National Cancer Institute. Dr. Brewer has received research funding from Merck, Pfizer, and GSK and served as a paid advisor for Merck. Dr. O’Leary reports no relevant financial relationships. Dr. Rodriguez received a grant from the Cancer Prevention Research Institute of Texas, and the study was supported by the Institute for Translational Sciences at the University of Texas Medical Branch.

Time to rebuild
A few months ago, after several months of considerable foot dragging, I wrote that I have accepted the American Academy of Pediatrics’ proclamation that we should begin to treat obesity as a disease.
While it may feel like we are just throwing in the towel, it sounds better if we admit that we may have reached the threshold beyond which total focus on prevention is not going to work.
I continue to be troubled by the lingering fear that, in declaring that obesity is a disease, we will suspend our current efforts at preventing the condition. Granted, most of these efforts at prevention have been woefully ineffective. However, I still believe that, much like ADHD, the rise in obesity in this country is a reflection of some serious flaws in our society. On the other hand, as an inveterate optimist I have not given up on the belief that we will find some yet-to-be-discovered changes in our societal fabric that will eventually turn the ship around.
With this somewhat contradictory combination of resignation and optimism in mind, I continue to seek out studies that hold some promise for prevention while we begin tinkering with the let’s-treat-it-like-a-disease approach.
I recently discovered a story about one such study from the Center for Economic and Social Research at the University of Southern California. Using data collected about adolescent dependents of military personnel, the researchers found that “exposure to a more advantageous built environment for more than 2 years was associated with lower probabilities of obesity.” Because more than half of these teenagers were living in housing that had been assigned by the military, the researchers could more easily control for a variety of factors some related to self-selection.
Interestingly, the data did not support associations between the adolescents’ diet, physical activity, or socioeconomic environments. The investigators noted that “more advantageous built environments were associated with lower consumption of unhealthy foods.” However, the study lacked the granularity to determine what segments of the built environment were most associated with the effect they were observing.
Like me, you may not be familiar with the term “built environment.” Turns out it is just exactly what we might expect – anything about the environment that is the result of human action – buildings, roadways, dams, neighborhoods – and what they do and don’t contain. For example, is the adolescent living in an environment that encourages walking or one that is overly motor vehicle–centric? Does his or her neighborhood have easily reachable grocery stores that offer a range of healthy foods or does the teenager live in a nutritional desert populated only by convenience stores? Is there ample space for outdoor physical activity?
The authors’ observation that the adolescents who benefited from living in advantageous environments had a lower consumption of unhealthy foods might suggest that access to a healthy diet might be a significant factor. For me, the take-home message is that in our search for preventive strategies we have barely scratched the surface. The observation that the associations these researchers were making was over a relatively short time span of 2 years should give us hope that if we think more broadly and creatively we may be to find solutions on a grand scale.
Over the last century we have built an environment that is clearly obesogenic. This paper offers a starting point from which we can learn which components of that environment are the most potent contributors to the obesity epidemic. Once we have that information the question remains: Can we find the political will to tear down and rebuilt?

He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Healthy lifestyle mitigates effect of childhood cancer
Although people who survive a childhood cancer are at an increased risk of developing and dying from subsequent cancers, as well as heart disease and stroke, they can reduce this risk by following a healthy lifestyle, say U.S. investigators.
This message comes from a retrospective analysis of more than 34,000 childhood cancer survivors, which found that 40 years after the initial cancer diagnosis, the cumulative all-cause mortality rate was 23.3%, compared with less than 5% in the general population.
However, following a healthy lifestyle was associated with a 20% reduction in health-related mortality, independent of other factors, the analysis showed. This rose even further, up to a 30% reduction, among individuals who did not have hypertension or diabetes.
The study was published online in The Lancet.
“We identified that long-term survivors of childhood cancer are experiencing a large number of deaths in excess of what would be expected for the general, aging population,” first author Stephanie Dixon, MD, MPH, oncology department, St. Jude Children’s Research Hospital, Memphis, Tenn., said in a press release.
“These excess deaths are predominantly due to the same leading causes of death as in the general population,” including subsequent cancers, heart disease, cerebrovascular disease/stroke, chronic liver and kidney disease, and infectious diseases, she noted. However, in these childhood cancer survivors they are occurring “at a younger age and higher rate.”
“What was most exciting to see,” Dr. Dixon added, “was that, independent of prior treatment exposures and sociodemographic factors, a healthy lifestyle and absence of hypertension or diabetes were each associated with a reduced risk of health-related mortality.”
“This is important because our goal is to extend the life span of survivors and to improve their ‘health span’ as well,” said senior author Greg Armstrong, MD, MSCE, chair of the department of epidemiology and cancer control at St. Jude.
As such, “the study highlights the importance of encouraging survivors to practice healthy behaviors and maintain good control of cardiovascular disease risk factors,” emphasized coauthor Melissa M. Hudson, MD, director of the cancer survivorship division at St. Jude.
Future research should focus on interventions for modifiable lifestyle and cardiovascular risk factors that “may need to be specifically tailored to survivors, with the goal of reducing chronic disease development” and extending their lifespan, the researchers said.
Late effects of treatment
Childhood cancer has a tremendous success rate: In the United States, the 5-year survival rate is now more than 85%.
However, long-term survivors experience excess morbidity and late mortality compared with the general population, both of which are “attributable to late effects of treatment,” the team pointed out.
Their study focused on individuals who had been diagnosed with cancer before they were 21 years old and who had survived at least 5 years after the cancer diagnosis.
The median age at diagnosis was 6 years, and the most common diagnoses were acute lymphoblastic leukemia (36%), Hodgkin lymphoma (11%), astrocytoma (10%), and kidney tumors (8%).
The team identified 34,230 survivors who had been treated between Jan. 1, 1970, and Dec. 31, 1999, at 31 institutions in the United States and Canada.
They represented approximately 20% of all childhood cancer survivors in the United States over the study period. The team noted that 56% of the survivors were male, and the majority (64%) were non-Hispanic White.
The date and causes of death through December 2017 were obtained via linkage to the National Death Index, and cancer treatment information was collated for 21,418 survivors who provided consent. Lifestyle factors – including smoking, alcohol use, physical activity, and unhealthy weight – were graded on a score of 0-4.
Over a median follow-up of 29.1 years, there were 5,916 deaths, with 34% attributable to the recurrence or progression of the primary cancer, and 51.2% attributable to other causes, such as subsequent neoplasms, and cardiac, pulmonary, and other health-related causes.
Overall, survivors were at an elevated risk of death compared with the general population, at a standardized mortality ratio of 5.6. This ratio peaked at 5-9 years after diagnosis at an 18.1-fold increased risk of death compared with the general population.
Forty years or more from the initial diagnosis, two-thirds of the 131 per 10,000 person-years excess deaths from health-related causes were due to the top three causes of health-related death in the general population, the team reported.
This included an absolute excess risk of death from cancer of 54 per 10,000 person-years, an excess risk of heart disease mortality of 27 per 10,000 person-years, and an excess risk of cerebrovascular disease mortality of 10 per 10,000 person-years.
The individual cases of death contributing the greatest excess risk were gastrointestinal cancers (11 per 10,000 person-years), cerebrovascular disease (10 per 10,000 person-years), ischemic heart disease (10 per 10,000 person-years), and valvular heart disease (9 per 10,000 person-years).
The good news is that following a healthy lifestyle was associated with a 20% reduction in health-related mortality versus an unhealthy lifestyle (P = .0020).
Moreover, following even a moderately healthy lifestyle was associated with a 10% reduction in health-related mortality, the researchers noted.
The study was supported by grants from the National Cancer Institute, St. Jude Children’s Research Hospital Cancer Center Support, and the American Lebanese-Syrian Associated Charities. The authors reported no relevant financial relationships.

Although people who survive a childhood cancer are at an increased risk of developing and dying from subsequent cancers, as well as heart disease and stroke, they can reduce this risk by following a healthy lifestyle, say U.S. investigators.
This message comes from a retrospective analysis of more than 34,000 childhood cancer survivors, which found that 40 years after the initial cancer diagnosis, the cumulative all-cause mortality rate was 23.3%, compared with less than 5% in the general population.
However, following a healthy lifestyle was associated with a 20% reduction in health-related mortality, independent of other factors, the analysis showed. This rose even further, up to a 30% reduction, among individuals who did not have hypertension or diabetes.
The study was published online in The Lancet.
“We identified that long-term survivors of childhood cancer are experiencing a large number of deaths in excess of what would be expected for the general, aging population,” first author Stephanie Dixon, MD, MPH, oncology department, St. Jude Children’s Research Hospital, Memphis, Tenn., said in a press release.
“These excess deaths are predominantly due to the same leading causes of death as in the general population,” including subsequent cancers, heart disease, cerebrovascular disease/stroke, chronic liver and kidney disease, and infectious diseases, she noted. However, in these childhood cancer survivors they are occurring “at a younger age and higher rate.”
“What was most exciting to see,” Dr. Dixon added, “was that, independent of prior treatment exposures and sociodemographic factors, a healthy lifestyle and absence of hypertension or diabetes were each associated with a reduced risk of health-related mortality.”
“This is important because our goal is to extend the life span of survivors and to improve their ‘health span’ as well,” said senior author Greg Armstrong, MD, MSCE, chair of the department of epidemiology and cancer control at St. Jude.
As such, “the study highlights the importance of encouraging survivors to practice healthy behaviors and maintain good control of cardiovascular disease risk factors,” emphasized coauthor Melissa M. Hudson, MD, director of the cancer survivorship division at St. Jude.
Future research should focus on interventions for modifiable lifestyle and cardiovascular risk factors that “may need to be specifically tailored to survivors, with the goal of reducing chronic disease development” and extending their lifespan, the researchers said.
Late effects of treatment
Childhood cancer has a tremendous success rate: In the United States, the 5-year survival rate is now more than 85%.
However, long-term survivors experience excess morbidity and late mortality compared with the general population, both of which are “attributable to late effects of treatment,” the team pointed out.
Their study focused on individuals who had been diagnosed with cancer before they were 21 years old and who had survived at least 5 years after the cancer diagnosis.
The median age at diagnosis was 6 years, and the most common diagnoses were acute lymphoblastic leukemia (36%), Hodgkin lymphoma (11%), astrocytoma (10%), and kidney tumors (8%).
The team identified 34,230 survivors who had been treated between Jan. 1, 1970, and Dec. 31, 1999, at 31 institutions in the United States and Canada.

Antimicrobial resistance requires a manifold response
BUENOS AIRES – Antimicrobial resistance (AMR) has become a global concern. And while one issue to be addressed is the deficit in research and development for new antibiotics, efforts to tackle this public health threat also should be directed toward promoting more rational prescription practices and strengthening the ability to identify the microorganisms responsible for infections, according to the World Health Organization. This was the conclusion reached at the fourth meeting of the WHO AMR Surveillance and Quality Assessment Collaborating Centres Network, which was held in Buenos Aires.
“We have to provide assistance to countries to ensure that the drugs are being used responsibly. We can come up with new antibiotics, but the issue at hand is not simply one of innovation: If nothing is done to correct inappropriate prescription practices and to overcome the lack of diagnostic laboratories at the country level, we’re going to miss out on those drugs as soon as they become available,” Kitty van Weezenbeek, MD, PhD, MPH, director of the AMR Surveillance, Prevention, and Control (AMR/SPC) Department at the WHO’s headquarters in Geneva, told this news organization.
Dr. van Weezenbeek pointed out that although there are currently no shortages of antimicrobials, the development and launch of new drugs that fight multidrug-resistant infections – infections for which there are few therapeutic options – has proceeded slowly. “It takes 10 to 15 years to develop a new antibiotic,” she said, adding that “the majority of pharmaceutical companies that had been engaged in the development of antimicrobials have filed for bankruptcy.”
In 2019, more people died – 1.2 million – from AMR than from malaria, tuberculosis, and HIV combined. Why are there so few market incentives when there is such a great need for those drugs? “One reason is that the pharmaceutical industry makes more money with long-term treatments, such as those for cancer and respiratory diseases. The other problem is that people everywhere are told not to use antibiotics,” said Dr. van Weezenbeek.
“A course of antibiotics lasts a few days, especially because we’re promoting rational use. Therefore, the trend is for the total amount of antimicrobials being used to be lower. So, it’s not as profitable,” added Carmem Lucia Pessoa-Silva, MD, PhD, head of the Surveillance, Evidence, and Laboratory Strengthening Unit of the WHO’s AMR/SPC Department.
On that note, Dr. van Weezenbeek mentioned that member countries are working with pharmaceutical companies and universities to address this problem. The WHO, for its part, has responded by implementing a global mechanism with a public health approach to create a “healthy” and equitable market for these medicines.
AMR is one of the top 10 global threats to human health. But it also has an impact on animal production, agricultural production, and the environment. Strategies to tackle AMR based on the One Health approach should involve all actors, social sectors, and citizens, according to Eva Jané Llopis, PhD, the representative of the Pan American Health Organization/WHO in Argentina.
At the root of the AMR problem is the widespread use of these drugs as growth promoters in animal production – for which several countries have enacted regulations – as well as “misunderstandings” between patients and physicians when there is not sufficient, timely access to laboratory diagnostics, especially in low- and middle-income countries.
“People think that if they’re given broad-spectrum antibiotics, they’re being prescribed the best antibiotics; and doctors, because there are no laboratory services, prescribe broad-spectrum antibiotics because they want to help patients. But that ends up causing more resistance to drugs, and thus, those antibiotics aren’t good for the patients,” said Dr. van Weezenbeek.
The WHO Global AMR and Use Surveillance System (GLASS) was launched in 2015. Its 2022 report, which marked the end of the system’s early implementation period, noted that the reported AMR rates are often lower in countries, territories, and areas with better testing coverage for most pathogen-drug-infection site combinations. However, as Dr. Pessoa-Silva acknowledged, monitoring “has not yet generated representative data,” because in many cases, countries either do not have surveillance systems or have only recently started implementing them.
Even so, the indicators that are available paint an increasingly worrisome picture. “For example, in many countries, resistance rates to first-line antibiotics were around 10%-20% with respect to Escherichia coli urinary tract infections and bloodstream bacteriologically confirmed infections. So, the risk of treatment failure is very high,” explained Dr. Pessoa-Silva.
The latest estimates indicate that every 2 or 3 minutes, somewhere in the world, a child dies from AMR. And the situation is particularly “dramatic” in neonatal intensive care units, where outbreaks of multidrug-resistant infections have a mortality rate of 50%, said Pilar Ramón-Pardo, MD, PhD, lead of the Special Program on AMR at the Pan American Health Organization, the WHO Regional Office for the Americas.
AMR rates also got worse during the pandemic because of the inappropriate prescription of massive amounts of antibiotics to hospitalized patients – something that was not in compliance with guidelines or protocols. Silvia Bertagnolio, MD, is an infectious disease specialist and the head of the Control and Response Strategies Unit in the WHO’s AMR Division. She spoke about the global clinical platform data pertaining to more than 1,500,000 patients who were hospitalized for COVID-19. Since 2020, 85% received antimicrobial treatment, despite the fact that only 5% had a concomitant infection at admission. “It’s easier to give antibiotics than to make a proper diagnosis,” said Dr. Bertagnolio.

Routine third-trimester ultrasounds can detect likely breech births
Implementing universal ultrasound during the third trimester of pregnancy significantly reduced the number of undiagnosed breech presentations, according to a study published in PLOS Medicine. The effects held if sonographers used a traditional ultrasound machine or if midwives used a handheld ultrasound tool to perform what is known as a point-of-care ultrasound (POCUS) procedure.
“Giving pregnant women a third-trimester scan reduces the rate of undetected breech in labor by over two-thirds, which reduces the chances of harm to the baby,” said Asma Khalil, MBBCh, MD, professor of obstetrics and maternal-fetal medicine at the University of London’s St. George’s Hospital, and a coauthor of the new study.
Routine ultrasounds typically are performed from the 10th to the 13th week of pregnancy, not during the third trimester, when the risk for a breech birth would be most apparent. Breech births occur in 3%-4% of pregnancies, raising the risk that babies will experience broken bones or hemorrhage. Knowing that breech is possible before birth enables physicians to discuss options with the pregnant woman in advance, Dr. Khalil said. These steps include rotating the baby in the uterus or conducting a cesarean delivery. Such counseling is not possible if breech is undetected until spontaneous or induced labor.
“Breech presentation at term is not very common, but diagnosing it prior to the onset of labor or induction of labor offers patients much more flexibility in terms of options and planning,” said Cecilia B. Leggett, MD, a resident in obstetrics and gynecology at Cedars-Sinai in Los Angeles. Dr. Leggett, who was not involved in the study, has shown that handheld devices are as accurate at assessing fetal weight as are standard ultrasound machines.
Two tools, same result
Dr. Khalil and her colleagues compared the rates of undiagnosed breech presentations before and after implementing universal third-semester ultrasound at two hospitals in the United Kingdom. The requirement began in 2020; the study compared the rate of undiagnosed breeches from the period of 2016-2020 with that of 2020-2021.
St. George’s Hospital in London used a traditional ultrasound machine that is read by a sonographer, whereas the Norfolk and Norwich University Hospitals, in Norwich, England, employed midwives to use a handheld ultrasound device.
The rate of undiagnosed breech cases declined from 14.2% at St. George’s before the universal ultrasound requirement (82 missed cases of 578 breech births) to 2.8% after the requirement began (7 missed cases of 251 breech births). The story was similar at Norfolk and Norwich, where 16.2% missed breech cases occurred before the requirement (27 of 167) and 3.5% missed cases were reported after it (5 of 142).
The increased accuracy of breech diagnosis before labor probably led to fewer cases of impaired blood flow to a baby’s brain at birth, Dr. Khalil’s group reported, as well as a probable reduction in the number of stillborn babies or those who die extremely young.
Traditional ultrasound scans read by sonographers are expensive, Dr. Khalil noted, whereas the portable handheld devices are much cheaper and could be used widely to improve detection of breech births. That step would require robust training about how to properly use these devices, Dr. Leggett said.
“As we see more and more studies come out about technology for POCUS, I think it’s important to keep in mind that we need the education about the tools to be as accessible as the tools themselves,” she said.
Dr. Leggett had no relevant financial relationships. Dr. Khalil is a vice president of the Royal College of Obstetricians and Gynaecologists, is a trustee and the treasurer of the International Society of Ultrasound in Obstetrics and Gynecology, and has lectured at and consulted in several ultrasound-based projects, webinars, and educational events.

These steps include rotating the baby in the uterus or conducting a cesarean delivery. Such counseling is not possible if breech is undetected until spontaneous or induced labor.
“Breech presentation at term is not very common, but diagnosing it prior to the onset of labor or induction of labor offers patients much more flexibility in terms of options and planning,” said Cecilia B. Leggett, MD, a resident in obstetrics and gynecology at Cedars-Sinai in Los Angeles. Dr. Leggett, who was not involved in the study, has shown that handheld devices are as accurate at assessing fetal weight as are standard ultrasound machines.
Two tools, same result
Dr. Khalil and her colleagues compared the rates of undiagnosed breech presentations before and after implementing universal third-semester ultrasound at two hospitals in the United Kingdom. The requirement began in 2020; the study compared the rate of undiagnosed breeches from the period of 2016-2020 with that of 2020-2021.
St. George’s Hospital in London used a traditional ultrasound machine that is read by a sonographer, whereas the Norfolk and Norwich University Hospitals, in Norwich, England, employed midwives to use a handheld ultrasound device.
The rate of undiagnosed breech cases declined from 14.2% at St. George’s before the universal ultrasound requirement (82 missed cases of 578 breech births) to 2.8% after the requirement began (7 missed cases of 251 breech births). The story was similar at Norfolk and Norwich, where 16.2% missed breech cases occurred before the requirement (27 of 167) and 3.5% missed cases were reported after it (5 of 142).
The increased accuracy of breech diagnosis before labor probably led to fewer cases of impaired blood flow to a baby’s brain at birth, Dr. Khalil’s group reported, as well as a probable reduction in the number of stillborn babies or those who die extremely young.
Traditional ultrasound scans read by sonographers are expensive, Dr. Khalil noted, whereas the portable handheld devices are much cheaper and could be used widely to improve detection of breech births. That step would require robust training about how to properly use these devices, Dr. Leggett said.
“As we see more and more studies come out about technology for POCUS, I think it’s important to keep in mind that we need the education about the tools to be as accessible as the tools themselves,” she said.
Dr. Leggett had no relevant financial relationships. Dr. Khalil is a vice president of the Royal College of Obstetricians and Gynaecologists, is a trustee and the treasurer of the International Society of Ultrasound in Obstetrics and Gynecology, and has lectured at and consulted in several ultrasound-based projects, webinars, and educational events.

Implementing universal ultrasound during the third trimester of pregnancy significantly reduced the number of undiagnosed breech presentations, according to a study published in PLOS Medicine. The effects held if sonographers used a traditional ultrasound machine or if midwives used a handheld ultrasound tool to perform what is known as a point-of-care ultrasound (POCUS) procedure.
“Giving pregnant women a third-trimester scan reduces the rate of undetected breech in labor by over two-thirds, which reduces the chances of harm to the baby,” said Asma Khalil, MBBCh, MD, professor of obstetrics and maternal-fetal medicine at the University of London’s St. George’s Hospital, and a coauthor of the new study.
Routine ultrasounds typically are performed from the 10th to the 13th week of pregnancy, not during the third trimester, when the risk for a breech birth would be most apparent. Breech births occur in 3%-4% of pregnancies, raising the risk that babies will experience broken bones or hemorrhage. Knowing that breech is possible before birth enables physicians to discuss options with the pregnant woman in advance, Dr. Khalil said.

What are the clinical implications of recent skin dysbiosis discoveries?
NEW ORLEANS – .
“There’s still a lot for us to learn,” Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, said at the annual meeting of the American Academy of Dermatology. “Multiple factors contribute to the variability in the skin microbiota, including age, sex, environment, immune system, host genotype, lifestyle, and pathobiology. The question becomes, when do these factors or impacts on the microbiota become clinically significant?”
According to Dr. Friedman, there are 10 times more bacteria cells than human cells in the human body, “but it’s not a fight to the finish; it’s not us versus them,” he said. “Together, we are a super organism.” There are also more than 500 species of bacteria on human skin excluding viruses and fungi, and each person carries up to 5 pounds of bacteria, which is akin to finding a new organ in the body.
“What’s so unique is that we each have our own bacterial fingerprint,” he said. “Whoever is sitting next to you? Their microbiota makeup is different than yours.”
Beyond genetics and environment, activities that can contribute to alterations in skin flora or skin dysbiosis include topical application of steroids, antibiotics, retinoids, harsh soaps, chemical and physical exfoliants, and resurfacing techniques. “With anything we apply or do to the skin, we are literally changing the home of many microorganisms, for good or bad,” he said.
In the realm of atopic dermatitis (AD), Staphylococcus aureus has been implicated as an offender in the pathophysiology of the disease. “It’s not about one single species of Staphylococcus, though,” said Dr. Friedman, who also is director of translational research at George Washington University. “We’re finding out that, depending on the severity of disease, Staph. epidermis may be part of the problem as opposed to it just being about Staph. aureus. Furthermore, and more importantly, these changes in the microbiota, specifically a decrease in microbial diversity, has been shown to precede a disease flare, highlighting the central role of maintaining microbial diversity and by definition, supporting the living barrier in our management of AD.”
With this in mind, researchers in one study used high-throughput sequencing to evaluate the microbial communities associated with affected and unaffected skin of 49 patients with AD before and after emollient treatment. Following 84 days of emollient application, clinical symptoms of AD improved in 72% of the study population and Stenotrophomonas species were significantly more abundant among responders.
Prebiotics, probiotics
“Our treatments certainly can positively impact the microbiota, as we have seen even recently with some of our new targeted therapies, but we can also directly provide support,” he continued. Prebiotics, which he defined as supplements or foods that contain a nondigestible ingredient that selectively stimulates the growth and/or activity of indigenous bacteria, can be found in many over-the-counter moisturizers.
For example, colloidal oatmeal has been found to support the growth of S. epidermidis and enhance the production of lactic acid. “We really don’t know much about what these induced changes mean from a clinical perspective; that has yet to be elucidated,” Dr. Friedman said.
In light of the recent attention to the early application of moisturizers in infants at high risk of developing AD in an effort to prevent or limit AD, “maybe part of this has to do with applying something that’s nurturing an evolving microbiota,” Dr. Friedman noted. “It’s something to think about.”
Yet another area of study involves the use of probiotics, which Dr. Friedman defined as supplements or foods that contain viable microorganisms that alter the microflora of the host. In a first-of-its-kind trial, researchers evaluated the safety and efficacy of self-administered topical Roseomonas mucosa in 10 adults and 5 children with AD. No adverse events or treatment complications were observed, and the topical R. mucosa was associated with significant decreases in measures of disease severity, topical steroid requirement, and S. aureus burden
In a more recent randomized trial of 11 patients with AD, Richard L. Gallo, MD, PhD, chair of dermatology, University of California, San Diego, and colleagues found that application of a personalized topical cream formulated from coagulase-negative Staphylococcus with antimicrobial activity against S. aureus reduced colonization of S. aureus and improved disease severity.
And in another randomized, controlled trial, Italian researchers enrolled 80 adults with mild to severe AD to receive a placebo or a supplement that was a mixture of lactobacilli for 56 days. They found that adults in the treatment arm showed an improvement in skin smoothness, skin moisturization, self-perception, and a decrease in the SCORing Atopic Dermatitis (SCORAD) index as well as in levels of inflammatory markers associated with AD.
Dr. Friedman also discussed postbiotics, nonviable bacterial products or metabolic byproducts from probiotic microorganisms that have biologic activity in the host. In one trial, French researchers enrolled 75 people with AD who ranged in age from 6 to 70 years to receive a cream containing a 5% lysate of the nonpathogenic bacteria Vitreoscilla filiformis, or a vehicle cream for 30 days. They found that compared with the vehicle, V. filiformis lysate significantly decreased SCORAD levels and pruritus; active cream was shown to significantly decrease loss of sleep from day 0 to day 29.
Dr. Friedman characterized these novel approaches to AD as “an exciting area, one we need to pay attention to. But what I really want to know is, aside from these purposefully made and marketed products that have pre- and postprobiotics, is there a difference with some of the products we use already? My assumption is that there is, but we need to see that data.”
Dr. Friedman disclosed that he is a consultant and/or advisory board member for Medscape/SanovaWorks, Oakstone Institute, L’Oréal, La Roche Posay, Galderma, Aveeno, Ortho Dermatologic, Microcures, Pfizer, Novartis, Lilly, Hoth Therapeutics, Zylo Therapeutics, BMS, Vial, Janssen, Novocure, Dermavant, Regeneron/Sanofi, and Incyte. He has also received grants from Pfizer, the Dermatology Foundation, Lilly, Janssen, Incyte, and Galderma.

COVID-19 in pregnancy affects growth in child’s first year of life
in a new analysis.
This “exaggerated growth pattern observed among infants with COVID-19 exposure may in some cases be a catch-up response to a prenatal growth deficit,” Mollie W. Ockene and colleagues wrote in a report published recently in the Journal of Clinical Endocrinology & Metabolism.
But given that lower birth weight and accelerated postnatal weight gain are risk factors for cardiometabolic disease, the findings “raise concern” about whether children born to mothers with prenatal COVID-19 go on to develop obesity, diabetes, or cardiovascular disease, senior coauthors Andrea G. Edlow, MD, and Lindsay T. Fourman, MD, of Massachusetts General Hospital, Boston, told this news organization.
Further studies in larger numbers of patients with longer follow-up and detailed assessments are needed, the researchers said, but this points to “a potentially increased cardiometabolic disease risk for the large global population of children with in utero COVID-19 exposure.”
It will be “important for clinicians caring for children with in utero exposure to maternal COVID-19 to be aware of this history,” Dr. Edlow and Dr. Fourman added, “and to view the child’s growth trajectory and metabolic risk factors in a holistic context that includes this prenatal infection exposure.”
COVID-19 vaccination important during and prior to pregnancy
The study also underscores the importance of primary prevention of COVID-19 among women who are contemplating pregnancy or who are already pregnant, the researchers noted, “including the need for widespread implementation of protective measures such as indoor masking and COVID-19 vaccination and boosting during or prior to pregnancy.”
Dr. Edlow and Dr. Fourman added, “Given the disproportionate impact that COVID-19 has had on historically marginalized populations, adverse health outcomes following in utero exposure to maternal COVID-19 may threaten to widen existing disparities in child health.”
On the other hand, although “COVID-19 vaccination rates lagged behind in minority populations following the initial vaccine rollout,” they noted, “these differences have fortunately narrowed over time, particularly for Hispanic individuals, though they do still persist in the Black population,” according to a recent report.
BMI trajectories during first year of life
In utero exposure to COVID-19 has been linked to fetal/neonatal morbidity and mortality, including stillbirth, preterm birth, preeclampsia, and gestational hypertension, but less is known about infant outcomes during the first year of life.
The researchers aimed to compare weight, length, and BMI trajectories over the first year of life in infants with, versus without, in utero exposure to COVID-19.
They identified 149 infants with in utero exposure to COVID-19 and 127 unexposed infants; all were born between March 30, 2020, and May 30, 2021, to mothers who participated in the Mass General Brigham COVID-19 Perinatal Biorepository.
The study excluded infants whose mothers received the vaccine (n = 5) or who had unclear vaccination status during pregnancy (n = 4) to reduce sample heterogeneity.
At the time of the study, few women had received the COVID-19 vaccine because vaccines were approved by the Food and Drug Administration for emergency use in December 2020 and the CDC recommended them for all pregnant women much later, in August 2021.
The researchers examined the weight, length, and BMI of the infants at birth, and at 2, 6, and 12 months, standardized using World Health Organization (WHO) growth charts.
Compared with mothers who did not have COVID-19 during pregnancy, those who had COVID-19 were younger (mean age, 32 vs. 34 years) and had a higher earliest BMI during pregnancy (29 vs. 26 kg/m2) and greater parity (previous births, excluding the index pregnancy, 1.2 vs. 0.9), and they were more likely to be Hispanic or Black and less likely to have private insurance.
Compared with infants exposed to COVID-19 in utero, infants who were not exposed were more likely to be male (47% vs. 55%).
Both infant groups were equally likely to be breastfed (90%).
Compared with the unexposed infants, infants born to mothers with prenatal COVID-19 had lower BMI z-scores at birth (effect size, −0.35; P = .03) and greater gain in BMI z-scores from birth to 12 months (effect size, 0.53; P = .03), but they had similar length at birth and over 12 months, after adjustment for maternal age at delivery, ethnicity, parity, insurance status, and earliest BMI during pregnancy, as well as infant sex, date of birth, and if applicable, history of breastfeeding.
The study received funding from the National Institutes of Health, Harvard Nutrition Obesity Research Center, Boston Area Diabetes Endocrinology Research Centers, American Heart Association, and Simons Foundation. Ms. Ockene has reported no relevant financial relationships. Dr. Edlow has reported being a consultant for Mirvie and receiving research funding from Merck outside the study. Dr. Fourman has reported serving as a consultant and receiving grant funding to her institution from Amryt outside the study. Disclosures for the other authors are listed with the article.

Edlow, MD, and Lindsay T. Fourman, MD, of Massachusetts General Hospital, Boston, told this news organization.
Further studies in larger numbers of patients with longer follow-up and detailed assessments are needed, the researchers said, but this points to “a potentially increased cardiometabolic disease risk for the large global population of children with in utero COVID-19 exposure.”
It will be “important for clinicians caring for children with in utero exposure to maternal COVID-19 to be aware of this history,” Dr. Edlow and Dr. Fourman added, “and to view the child’s growth trajectory and metabolic risk factors in a holistic context that includes this prenatal infection exposure.”
COVID-19 vaccination important during and prior to pregnancy
The study also underscores the importance of primary prevention of COVID-19 among women who are contemplating pregnancy or who are already pregnant, the researchers noted, “including the need for widespread implementation of protective measures such as indoor masking and COVID-19 vaccination and boosting during or prior to pregnancy.”
Dr. Edlow and Dr. Fourman added, “Given the disproportionate impact that COVID-19 has had on historically marginalized populations, adverse health outcomes following in utero exposure to maternal COVID-19 may threaten to widen existing disparities in child health.”
On the other hand, although “COVID-19 vaccination rates lagged behind in minority populations following the initial vaccine rollout,” they noted, “these differences have fortunately narrowed over time, particularly for Hispanic individuals, though they do still persist in the Black population,” according to a recent report.
BMI trajectories during first year of life
In utero exposure to COVID-19 has been linked to fetal/neonatal morbidity and mortality, including stillbirth, preterm birth, preeclampsia, and gestational hypertension, but less is known about infant outcomes during the first year of life.
The researchers aimed to compare weight, length, and BMI trajectories over the first year of life in infants with, versus without, in utero exposure to COVID-19.
They identified 149 infants with in utero exposure to COVID-19 and 127 unexposed infants; all were born between March 30, 2020, and May 30, 2021, to mothers who participated in the Mass General Brigham COVID-19 Perinatal Biorepository.
The study excluded infants whose mothers received the vaccine (n = 5) or who had unclear vaccination status during pregnancy (n = 4) to reduce sample heterogeneity.
At the time of the study, few women had received the COVID-19 vaccine because vaccines were approved by the Food and Drug Administration for emergency use in December 2020 and the CDC recommended them for all pregnant women much later, in August 2021.
The researchers examined the weight, length, and BMI of the infants at birth, and at 2, 6, and 12 months, standardized using World Health Organization (WHO) growth charts.
Compared with mothers who did not have COVID-19 during pregnancy, those who had COVID-19 were younger (mean age, 32 vs. 34 years) and had a higher earliest BMI during pregnancy (29 vs. 26 kg/m2) and greater parity (previous births, excluding the index pregnancy, 1.2 vs. 0.9), and they were more likely to be Hispanic or Black and less likely to have private insurance.
Compared with infants exposed to COVID-19 in utero, infants who were not exposed were more likely to be male (47% vs. 55%).
Both infant groups were equally likely to be breastfed (90%).
Compared with the unexposed infants, infants born to mothers with prenatal COVID-19 had lower BMI z-scores at birth (effect size, −0.35; P = .03) and greater gain in BMI z-scores from birth to 12 months (effect size, 0.53; P = .03), but they had similar length at birth and over 12 months, after adjustment for maternal age at delivery, ethnicity, parity, insurance status, and earliest BMI during pregnancy, as well as infant sex, date of birth, and if applicable, history of breastfeeding.
The study received funding from the National Institutes of Health, Harvard Nutrition Obesity Research Center, Boston Area Diabetes Endocrinology Research Centers, American Heart Association, and Simons Foundation. Ms. Ockene has reported no relevant financial relationships. Dr. Edlow has reported being a consultant for Mirvie and receiving research funding from Merck outside the study.

Noisy incubators could stunt infant hearing
Incubators save the lives of many babies, but new data suggest that the ambient noise associated with the incubator experience could put babies’ hearing and language development skills at risk.
Previous studies have shown that the neonatal intensive care unit is a noisy environment, but specific data on levels of sound inside and outside incubators are limited, wrote Christoph Reuter, MA, a musicology professor at the University of Vienna, and colleagues.
“By the age of 3 years, deficits in language acquisition are detectable in nearly 50% of very preterm infants,” and high levels of NICU noise have been cited as possible contributors to this increased risk, the researchers say.
In a study published in Frontiers in Pediatrics, the researchers aimed to compare real-life NICU noise with previously reported levels to describe the sound characteristics and to identify resonance characteristics inside an incubator.
The study was conducted at the Pediatric Simulation Center at the Medical University of Vienna. The researchers placed a simulation mannequin with an ear microphone inside an incubator. They also placed microphones outside the incubator to collect measures of outside noise and activity involved in NICU care.
Data regarding sound were collected for 11 environmental noises and 12 incubator handlings using weighted and unweighted decibel levels. Specific environmental noises included starting the incubator engine; environmental noise with incubator off; environmental noise with incubator on; normal conversation; light conversation; laughter; telephone sounds; the infusion pump alarm; the monitor alarm (anomaly); the monitor alarm (emergency); and blood pressure measurement.
The 12 incubator handling noises included those associated with water flap, water pouring into the incubator, incubator doors opening properly, incubators doors closing properly, incubator doors closing improperly, hatch closing, hatch opening, incubator drawer, neighbor incubator doors closing (1.82 m distance), taking a stethoscope from the incubator wall, putting a stethoscope on the incubator, and suctioning tube. Noise from six levels of respiratory support was also measured.
The researchers reported that the incubator tended to dampen most sounds but also that some sounds resonated inside the incubator, which raised the interior noise level by as much as 28 decibels.
Most of the measures using both A-weighted decibels (dBA) and sound pressure level decibels (dBSPL) were above the 45-decibel level for neonatal sound exposure recommended by the American Academy of Pediatrics. The measurements (dBA) versus unweighted (dBSPL) are limited in that they are designed to measure low levels of sound and therefore might underestimate proportions of high and low frequencies at stronger levels, the researchers acknowledge.
Overall, most measures were clustered in the 55-75 decibel range, although some sound levels for incubator handling, while below levels previously reported in the literature, reached approximately 100 decibels.
The noise involved inside the incubator was not perceived as loud by those working with the incubator, the researchers note.
As for resonance inside the incubator, the researchers measured a low-frequency main resonance of 97 Hz, but they write that this resonance can be hard to capture in weighted measurements. However, the resonance means that “noises from the outside sound more tonal inside the incubator, booming and muffled as well as less rough or noisy,” and sounds inside the incubator are similarly affected, the researchers say.
“Most of the noise situations described in this manuscript far exceed not only the recommendation of the AAP but also international guidelines provided by the World Health Organization and the U.S. Environmental Protection Agency,” which recommend, respectively, maximum dBA levels of 35 dBA and 45 dBA for daytime and 30 dBA and 35 dBA for night, the researchers indicate.
Potential long-term implications are that babies who spend time in the NICU are at risk for hearing impairment, which could lead to delays in language acquisition, they say.
The findings were limited by several factors, including the variance among the incubators, which prevents generalizability, the researchers note. Other limitations include the use of a simulation room rather than everyday conditions, in which the environmental sounds would likely be even louder.
However, the results provide insights into the specifics of incubator and NICU noise and suggest that sound be a consideration in the development and promotion of incubators to help protect the hearing of the infants inside them, the researchers conclude.
A generalist’s take
“This is an interesting study looking at the level and character of the sound experienced by preterm infants inside an incubator and how it may compare to sounds experienced within the mother’s womb,” said Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, in an interview.
In society at large, “there has been more focus lately on the general environment and its effect on health, and this study is a unique take on this concept,” he said. “Although in general the incubators work to dampen external sounds, low-frequency sounds may actually resonate more inside the incubators, and taps on the outside or inside of the incubator itself are amplified within the incubator,” he noted. “It is sad but not surprising that the decibel levels experienced by the infants in the incubators exceed the recommended levels recommended by AAP.”
As for additional research, “it would be interesting to see the results of trials looking at various short- or long-term outcomes experienced by infants exposed to a lower-level noise compared to the current levels,” Dr. Joos told this news organization.
A neonatologist’s perspective
“As the field of neonatology advances, we are caring for an ever-growing number of extremely preterm infants,” said Caitlin M. Drumm, MD, of Walter Reed National Military Medical Center, Bethesda, Md., in an interview.
“These infants will spend the first few months of their lives within an incubator in the neonatal intensive care unit, so it is important to understand the potential long-term implications of environmental effects on these vulnerable patients,” she said.
“As in prior studies, it was not surprising that essentially every environmental, handling, or respiratory intervention led to noise levels higher than the limit recommended by the American Academy of Pediatrics,” Dr. Drumm said. “What was surprising was just how high above the 45-dB recommended noise limit many environmental stimuli are. For example, the authors cite respiratory flow rates of 8 L/min or higher as risky for hearing health at 84.72 dBSPL, “ she said.
The key message for clinicians is to be aware of noise levels in the NICU, Dr. Drumm said. “Environmental stimuli as simple as putting a stethoscope on the incubator lead to noise levels well above the limit recommended by the American Academy of Pediatrics. The entire NICU care team has a role to play in minimizing environmental sound hazards for our most critically ill patients.”
Looking ahead, “future research should focus on providing more information correlating neonatal environmental sound exposure to long-term hearing and neurodevelopmental outcomes,” she said.
The study received no outside funding. The researchers report no relevant financial relationships. Dr. Joos serves on the editorial advisory board of Pediatric News. Dr. Drumm has disclosed no relevant financial relationships.

SARS-CoV-2 crosses placenta and infects brains of two infants: ‘This is a first’
, according to a study published online today in Pediatrics .
One of the infants died at 13 months and the other remained in hospice care at time of manuscript submission.
Lead author Merline Benny, MD, with the division of neonatology, department of pediatrics at University of Miami, and colleagues briefed reporters today ahead of the release.
“This is a first,” said senior author Shahnaz Duara, MD, medical director of the Neonatal Intensive Care Unit at Holtz Children’s Hospital, Miami, explaining it is the first study to confirm cross-placental SARS-CoV-2 transmission leading to brain injury in a newborn.
Both infants negative for the virus at birth
The two infants were admitted in the early days of the pandemic in the Delta wave to the neonatal ICU at Holtz Children’s Hospital at University of Miami/Jackson Memorial Medical Center.
Both infants tested negative for the virus at birth, but had significantly elevated SARS-CoV-2 antibodies in their blood, indicating that either antibodies crossed the placenta, or the virus crossed and the immune response was the baby’s.
Dr. Benny explained that the researchers have seen, to this point, more than 700 mother/infant pairs in whom the mother tested positive for COVID in Jackson hospital.
Most who tested positive for COVID were asymptomatic and most of the mothers and infants left the hospital without complications.
“However, (these) two babies had a very unusual clinical picture,” Dr. Benny said.
Those infants were born to mothers who became COVID positive in the second trimester and delivered a few weeks later.
Seizures started on day 1 of life
The babies began to seize from the first day of life. They had profound low tone (hypotonia) in their clinical exam, Dr. Benny explained.
“We had absolutely no good explanation for the early seizures and the degree of brain injury we saw,” Dr. Duara said.
Dr. Benny said that as their bodies grew, they had very small head circumference. Unlike some babies born with the Zika virus, these babies were not microcephalic at birth. Brain imaging on the two babies indicated significant brain atrophy, and neurodevelopment exams showed significant delay.
Discussions began with the center’s multidisciplinary team including neurologists, pathologists, neuroradiologists, and obstetricians who cared for both the mothers and the babies.
The experts examined the placentas and found some characteristic COVID changes and presence of the COVID virus. This was accompanied by increased markers for inflammation and a severe reduction in a hormone critical for placental health and brain development.
Examining the infant’s autopsy findings further raised suspicions of maternal transmission, something that had not been documented before.
Coauthor Ali G. Saad, MD, pediatric and perinatal pathology director at Miami, said, “I have seen literally thousands of brains in autopsies over the last 14 years, and this was the most dramatic case of leukoencephalopathy or loss of white matter in a patient with no significant reason. That’s what triggered the investigation.”
Mothers had very different presentations
Coauthor Michael J. Paidas, MD, with the department of obstetrics, gynecology, and reproductive sciences at Miami, pointed out that the circumstances of the two mothers, who were in their 20s, were very different.
One mother delivered at 32 weeks and had a very severe COVID presentation and spent a month in the intensive care unit. The team decided to deliver the child to save the mother, Dr. Paidas said.
In contrast, the other mother had asymptomatic COVID infection in the second trimester and delivered at full term.
He said one of the early suspicions in the babies’ presentations was hypoxic ischemic encephalopathy. “But it wasn’t lack of blood flow to the placenta that caused this,” he said. “As best we can tell, it was the viral infection.”
Instances are rare
The researchers emphasized that these instances are rare and have not been seen before or since the period of this study to their knowledge.
Dr. Duara said, “This is something we want to alert the medical community to more than the general public. We do not want the lay public to be panicked. We’re trying to understand what made these two pregnancies different, so we can direct research towards protecting vulnerable babies.”
Previous data have indicated a relatively benign status in infants who test negative for the COVID virus after birth. Dr. Benny added that COVID vaccination has been found safe in pregnancy and both vaccination and breastfeeding can help passage of antibodies to the infant and help protect the baby. Because these cases happened in the early days of the pandemic, no vaccines were available.
Dr. Paidas received funding from BioIncept to study hypoxic-ischemic encephalopathy with Preimplantation Factor, is a scientific advisory board member, and has stock options. Dr. Paidas and coauthor Dr. Jayakumar are coinventors of SPIKENET, University of Miami, patent pending 2023. The other authors have no conflicts of interest to disclose.

Both infants tested negative for the virus at birth, but had significantly elevated SARS-CoV-2 antibodies in their blood, indicating that either antibodies crossed the placenta, or the virus crossed and the immune response was the baby’s.
Dr. Benny explained that the researchers have seen, to this point, more than 700 mother/infant pairs in whom the mother tested positive for COVID in Jackson hospital.
Most who tested positive for COVID were asymptomatic and most of the mothers and infants left the hospital without complications.
“However, (these) two babies had a very unusual clinical picture,” Dr. Benny said.
Those infants were born to mothers who became COVID positive in the second trimester and delivered a few weeks later.
Seizures started on day 1 of life
The babies began to seize from the first day of life. They had profound low tone (hypotonia) in their clinical exam, Dr. Benny explained.
“We had absolutely no good explanation for the early seizures and the degree of brain injury we saw,” Dr. Duara said.
Dr. Benny said that as their bodies grew, they had very small head circumference. Unlike some babies born with the Zika virus, these babies were not microcephalic at birth. Brain imaging on the two babies indicated significant brain atrophy, and neurodevelopment exams showed significant delay.
Discussions began with the center’s multidisciplinary team including neurologists, pathologists, neuroradiologists, and obstetricians who cared for both the mothers and the babies.
The experts examined the placentas and found some characteristic COVID changes and presence of the COVID virus. This was accompanied by increased markers for inflammation and a severe reduction in a hormone critical for placental health and brain development.
Examining the infant’s autopsy findings further raised suspicions of maternal transmission, something that had not been documented before.
Coauthor Ali G. Saad, MD, pediatric and perinatal pathology director at Miami, said, “I have seen literally thousands of brains in autopsies over the last 14 years, and this was the most dramatic case of leukoencephalopathy or loss of white matter in a patient with no significant reason. That’s what triggered the investigation.”
Mothers had very different presentations
Coauthor Michael J. Paidas, MD, with the department of obstetrics, gynecology, and reproductive sciences at Miami, pointed out that the circumstances of the two mothers, who were in their 20s, were very different.
One mother delivered at 32 weeks and had a very severe COVID presentation and spent a month in the intensive care unit. The team decided to deliver the child to save the mother, Dr. Paidas said.
In contrast, the other mother had asymptomatic COVID infection in the second trimester and delivered at full term.
He said one of the early suspicions in the babies’ presentations was hypoxic ischemic encephalopathy. “But it wasn’t lack of blood flow to the placenta that caused this,” he said. “As best we can tell, it was the viral infection.”
Instances are rare
The researchers emphasized that these instances are rare and have not been seen before or since the period of this study to their knowledge.
Dr. Duara said, “This is something we want to alert the medical community to more than the general public. We do not want the lay public to be panicked. We’re trying to understand what made these two pregnancies different, so we can direct research towards protecting vulnerable babies.”
Previous data have indicated a relatively benign status in infants who test negative for the COVID virus after birth. Dr. Benny added that COVID vaccination has been found safe in pregnancy and both vaccination and breastfeeding can help passage of antibodies to the infant and help protect the baby. Because these cases happened in the early days of the pandemic, no vaccines were available.
Dr. Paidas received funding from BioIncept to study hypoxic-ischemic encephalopathy with Preimplantation Factor, is a scientific advisory board member, and has stock options. Dr. Paidas and coauthor Dr. Jayakumar are coinventors of SPIKENET, University of Miami, patent pending 2023. The other authors have no conflicts of interest to disclose.
FROM PEDIATRICS
Infant and maternal weight gain together amplify obesity risk
Rapid weight gain (RWG) in infants and the mother’s prepregnancy overweight have a synergistic effect in increasing the odds that a child will develop overweight or obesity, new research suggests.
Findings were published online in Pediatrics.
Each factor has independently been associated with higher risk of childhood obesity but whether the two factors together exacerbate the risk has not been well studied, according to the authors led by Stephanie Gilley, MD, PhD, department of pediatrics, section of nutrition, University of Colorado at Denver, Aurora.
“Pediatric providers should monitor infants for RWG, especially in the context of maternal obesity, to reduce future risk of obesity,” the authors conclude.
Dr. Gilley’s team studied mother-infant dyads (n = 414) from the Healthy Start Study, an observational prebirth cohort. RWG was defined as a weight-for-age z score increase of at least 0.67 from birth to 3-7 months.
They found that RWG boosted the link between prepregnancy body mass index (ppBMI) and BMI z score, especially in female infants. Females exposed to both maternal obesity with RWG had an average BMI at the 94th percentile (1.50 increase in childhood BMI z score) “nearly at the cutoff for classification of obesity,” compared with those exposed to normal ppBMI with no RWG, who had an average childhood BMI at the 51st percentile.
“Currently, our nutrition recommendations as pediatricians are that all children are fed the same, essentially, after they’re born. We don’t have different growth parameters or different trajectories or targets for children who may have had different in utero exposures,” Dr. Gilley said.
Do some children need more monitoring for RWG?
Though we can’t necessarily draw conclusions from this one study, she says, the findings raise the question of whether children who were exposed in utero to obesity should be monitored for RWG more closely.
Lydia Shook, MD, Mass General Brigham maternal-fetal specialist and codirector of the Diabetes in Pregnancy Program at Massachusetts General Hospital in Boston, said she was struck by the finding in this study that with female infants, but not males, RWG significantly modified the association between ppBMI and early childhood BMI z scores.
“It’s an interesting finding and should be followed up with larger cohorts,” she said, noting that some previous studies have shown males are more vulnerable to maternal obesity and RWG.
“[Often] when we stratify by sex, you really need larger groups to be able to see the differences well,” Dr. Shook said.
She said she also found it interesting that when the researchers adjusted for breastfeeding status or caloric intake in childhood, the findings did not substantially change.
“That’s something that would warrant further investigation in an observational study or controlled trial,” Dr. Shook said.
Preventing rapid weight gain
The authors note that they did not consider possible interventions for preventing RGW in the study, although there are many, Dr. Gilley said.
Dr. Gilley also noted that a limitation of this study is that the population studied was primarily White.
Recent studies have shown the benefits of responsive parenting (RP) interventions, including a large study in 2022 geared toward Black families to teach better infant sleep practices as a way to prevent rapid weight gain.
That study, which tested the SAAF intervention, (Strong African American Families) found that “RP infants were nearly half as likely to experience upward crossing of two major weight-for-age percentile lines (14.1%), compared with control infants (24.2%); P = .09; odds ratio, 0.52; 95% confidence interval, 0.24-1.12.”
Along with sleep interventions, Dr. Gilley said, some researchers are studying the effects on RWG of better paternal engagement, or more involvement with the Women, Infants, and Children program, particularly with lower-income families.
Other studies have looked at breastfeeding vs. formula feeding – “but there have been mixed results there” – and responsive feeding practices, such as teaching families to recognize when a baby is full.
Dr. Gilley said she hopes this work will help broaden the thinking when it comes to infant weight gain.
“We spend a lot of time thinking about babies who are not growing fast enough and very little time thinking about babies who are growing too fast,” she said, “especially in those first 4-6 months of life.”
Dr. Gilley points to a study that illustrates that point. Pesch et al. concluded in a 2021 study based on interviews that pediatricians “are uncertain about the concept, definition, management, and long-term risks of rapid infant weight gain.”
