Does racial bias taint the Apgar score?
Experts say overhaul needed
In 1952, when Dr. Virginia Apgar developed her 10-point scale for assessing neonates’ health, the U.S. obstetrical anesthesiologst may not have foreseen it would one day become one of the commonest medical tests in the world.
Assigned even before the mother first holds her newborn, the score rapidly evaluates neonates with a score of 0-10, which leads to an algorithm of potential medical interventions. The scale evaluates heart rate, respiratory effort, muscle tone, reflex response, and skin coloring (typically described as blue body, pink body/blue limbs, or pink body).
“The Apgar is a very important tool used in millions of babies around the world in the very first minute after birth,” said Amos Grunebaum, MD, a professor of obstetrics and gynecology at Hofstra University, Hempstead, N.Y., and director of perinatal research at Northwell Lenox Hill Hospital in Manhattan.
But recently the venerable system has increasingly come under fire for colorism and racial bias, with some calling for an overhaul. That pressure is due to the 2 out of 10 points allotted to an overall “pink” skin tone, a measure that lowers the scores of non-White newborns and may expose them to unnecessary measures such as resuscitation, neonatal intensive care, and intubation.
“This is their first encounter with systemic racism,” said Dr. Grunebaum in an interview. “The score is prejudiced against Black babies because they can’t get perfect scores.”
Propagating ‘race-based medicine’
Concern about racial bias embedded in the Apgar score is not new, Dr. Grunebaum noted.
“Decades ago, when I was doing my training in Brooklyn, the nurses said that using skin color was ridiculous since Black and brown babies couldn’t be pink. And skin color looks different in different lighting. Dr. Apgar herself recognized the problem.”
Furthermore, men see color differently than women do, and some people are actually color-blind.“But nobody wanted to speak out,” Dr. Grunebaum said. “It was like the emperor’s new clothes scenario.”
In his view, embedding skin color scoring into basic data and health care decisions propagates race-based medicine. “It should not be used for White, Black, or brown babies,” he said.
Removing the skin color portion of the Apgar score – and its racial, colorist, and ethnic bias – will provide more accurate and equitable evaluation of newborn babies worldwide, Dr. Grunebaum said.
“I think there’s a pretty good argument to be made that the skin color measure should be eliminated,” agreed Sara E. Edwards, MD, an obstetrician-gynecologist at the University of Illinois Hospital in Chicago, who has also studied Apgar and racial bias in the clinical care of Black babies.
And such clinical bias may soon be illegal in the United States thanks to a proposed new antidiscrimination provision to the Affordable Care Act regarding the use of clinical algorithms in decision-making. The proposed section, § 92.210, states that a covered entity must not discriminate against any individual on the basis of race, color, national origin, sex, age, or disability through clinical algorithms used in decision-making. Hospitals may soon have to alter clinical algorithms in response.
Dr. Grunebaum’s research in the area of clinical racism includes a large 2022 cohort study of almost 10 million mothers and more than 8 million fathers using 2016-2019 natality data from the National Center for Health Statistics, and Division of Vital Statistics. This study found that Black newborns had a less than 50% chance of having a 5-minute Apgar score of 10, compared with White newborns. White babies, both non-Hispanic and Hispanic, had the highest proportion of perfect 10s.
But can the 2-point skin tone indicator be easily replaced? According to Dr. Grunebaum, substituting indicators such as oral mucosa color or oximetry readings are not satisfactory either. “For one thing, oximetry gives different readings in Black [people],” he said.
In her group’s Apgar research, Dr. Edwards found that care providers applied variable and inaccurate scores based on neonatal race – independently of clinical factors and umbilical-cord gas values.
“In Black neonates umbilical cord gases were not in agreement with lower Apgar scores,” she said. In her view, these inaccuracies point to the existence of colorism and racial bias among health care providers.
Bias ‘creeping in’ to neonatal care
Dr. Edwards’s research was prompted by anecdotal observations that Black babies generally had lower Apgar scores and were more frequently sent to the NICU. “Admission to the NICU can have a negative effect on maternal-child bonding and contribute to PTSD in mothers,” she said.
Her group looked at Apgar scores by race for the year 2019 in an academic hospital cohort of 977 neonates, of whom 56.5% were Black, while controlling for confounding clinical factors.
“Our anecdotal observations of how we score Black neonates were confirmed,” she said. Providers assigned Black babies significantly lower Apgar scores at 1 minute and 5 minutes (odds ratios, .63 and .64) when controlling for umbilical artery gases, gestational age, and maternal-fetal complications.
This difference was specifically associated with lower assigned color Apgar scores at 1 minute (odds ratio, .52). Moreover, full-term Black neonates were sent to neonatal intensive care at higher rates (odds ratio, 1.29) than non-Black neonates when controlling for all the above factors.
Providers applied inaccurate Apgar scores to Black neonates given that the umbilical cord gases were not in agreement with lower Apgar scores, suggesting that colorism and racial biases do exist among health care providers. “We saw bias creeping in because of subjective decisions about color,” Dr. Edwards said. But by the more objective measure of umbilical-cord gas, Black neonates did not have the abnormal values to support NICU admission. The mean umbilical artery pH was 7.259 for Black vs. 7.256 for non-Black neonates.
The solution may lie in switching to an 8 out of 8 score or looking at other indicators such as the eyes and the nail beds, she said. “Or there may be a way to score skin tone accurately when providers are appropriately trained to do so on neonates of all races, to recognize what a well-perfused skin color looks like in all babies.”
New scoring system needed
Interest in this issue continues. In 2022, a population study was conducted by Emma Gillette, MPH, of the Icahn School of Medicine at Mount Sinai, New York, and colleagues in a cohort of almost 7 million singletons born in 2016-2017.
“We found that overall, Apgar scores were highly associated with mortality across the first year of life,” Ms. Gillette said in an interview. “But non-Hispanic Black infants were more likely to be assigned low Apgar scores compared to White infants, and the odds of death in the first year of life are not as strongly correlated with Apgar scores as in White infants.”
That finding was surprising. “Apgar scores are meant to be an indicator of newborn health and well-being and predictors of infant mortality, and therefore should not vary significantly by race or skin color,” she said. “So I think further study into the component scores of the Apgar score is warranted to try to tease out the reasons behind the differences we’re seeing.”
Ms. Gillette agreed that the skin coloring component of the variable could be inaccurate since variables related to skin color more generally are subjective and difficult to measure. What’s needed is a scoring system that performs equally well across racial groups.
In the meantime, some clinicians may be making practical accommodations. “I hate to tell you, but some people fake the skin score,” said Dr. Grunebaum. “I recently asked a doctor from Ethiopia how they handled it there, and he laughed and said they just automatically give skin color a 2. But faking it is not what you should have to do in medicine.”
Dr. Grunebaum, Dr. Edwards, and Ms. Gillette disclosed no relevant competing interests with respect to their comments.

Nails falling off in a 3-year-old
When the nails peel off from the proximal nail folds, the clinical term is onychomadesis and it is important to ask about recent infections or severe metabolic stressors. In children and adults, onychomadesis on multiple fingers may occur after infections and has been associated with hand-foot-mouth disease caused by common viral infections—especially strains of coxsackievirus.1
Because shed nails show evidence of viral infection, one hypothesis for their peeling off is that the tissue of the nail matrix is infected, leading to metabolic changes. As the nail matrix returns to normal function, a new nail is made and ultimately will replace the nail that has come off. In healthy US adults, fingernails grow 3.47 mm per month on average while toenails grow 1.62 mm per month on average.2
Sometimes it’s hard to elicit a history of a very mild viral illness weeks or months after it has resolved. Asking specifically about mouth ulcers may help. If there is a history of a viral illness, no specific work-up or treatment is necessary. Patients may be reassured that nails will improve over several months without lasting effects.
In this case, the patient and her family were given reassurance and the nails returned to normal within a few months.

New guidelines for MTX use in pediatric inflammatory skin disease unveiled
While the typical dose of methotrexate (MTX) for inflammatory disease in pediatric patients varies in published studies, the maximum dose is considered to be 1 mg/kg and not to exceed 25 mg/week. In addition, test doses are not necessary for pediatric patients starting low dose (1 mg/kg or less) MTX for inflammatory skin disease, and the onset of efficacy with MTX may take 8-16 weeks.
published online in Pediatric Dermatology.
“Methotrexate is a cost-effective, readily accessible, well-tolerated, useful, and time-honored option for children with a spectrum of inflammatory skin diseases,” project cochair Elaine C. Siegfried, MD, professor of pediatrics and dermatology at Saint Louis University, told this news organization. “Although considered an ‘immune suppressant’ by some, it is more accurately classified as an immune modulator and has been widely used for more than 50 years, and remains the standard of care when administered at very high doses and intrathecally in children with acute lymphoblastic leukemia – a practice that supports safety. But many details that support optimized treatment are not widely appreciated.”
In their guidelines document, Dr. Siegfried and her 22 coauthors noted that Food and Drug Administration labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata. “Furthermore, some clinicians may be unfamiliar or uncomfortable prescribing medications off label for pediatric patients, causing delayed initiation, premature drug discontinuation, or use of less advantageous alternatives,” they wrote.
To address this unmet need, Dr. Siegfried and the other committee members used a modified Delphi process to reach agreement on recommendations related to five key topic areas: indications and contraindications, dosing, interactions with immunizations and medications, potential for and management of adverse effects, and monitoring needs. Consensus was predefined as at least 70% of participants rating a statement as 7-9 on the Likert scale. The effort to develop 46 recommendations has been a work in progress for almost 5 years, “somewhat delayed by the pandemic,” Dr. Siegfried, past president and director of the American Board of Dermatology, said in an interview. “But it remains relevant, despite the emergence of biologics and JAK inhibitors for treating inflammatory skin conditions in children. Although the mechanism-of-action of low-dose MTX is not clear, it may overlap with the newer small molecules.”
The guidelines contain several pearls to guide optimal dosing, including the following key points:
- MTX can be discontinued abruptly without adverse effects, other than the risk of disease worsening.
- Folic acid supplementation (starting at 1 mg/day, regardless of weight) is an effective approach to minimizing associated gastrointestinal adverse effects.
- Concomitant use of MTX and antibiotics (including trimethoprim-sulfamethoxazole) and NSAIDS are not contraindicated for most pediatric patients treated for inflammatory skin disease.
- Live virus vaccine boosters such as varicella-zoster virus (VZV) and measles, mumps, and rubella (MMR) are not contraindicated in patients taking MTX; there are insufficient data to make recommendations for or against primary immunization with MMR vaccine in patients taking MTX; inactivated vaccines should be given to patients taking MTX.
- Routine surveillance laboratory monitoring (i.e., CBC with differential, alanine transaminase, aspartate aminotransferase, creatinine) is recommended at baseline, after 1 month of treatment, and every 3-4 months thereafter.
- Transient transaminase elevation (≤ 3 upper limit normal for < 3 months) is not uncommon with low-dose MTX and does not usually require interruption of MTX. The most likely causes are concomitant viral infection, MTX dosing within 24 hours prior to phlebotomy, recent administration of other medications (such as acetaminophen), and/or recent alcohol consumption.
- Liver biopsy is not indicated for routine monitoring of pediatric patients taking low-dose MTX.
According to Dr. Siegfried, consensus of the committee members was lowest on the need for a test dose of MTX.
Overall, she said in the interview, helping to craft the guidelines caused her to reflect on how her approach to using MTX has evolved over the past 35 years, after treating “many hundreds” of patients. “I was gratified to confirm similar practice patterns among my colleagues,” she added.
The project’s other cochair was Heather Brandling-Bennett, MD, a dermatologist at Seattle Children’s Hospital. This work was supported by a grant from the Pediatric Dermatology Research Alliance (PeDRA), with additional funding from the National Eczema Association and the National Psoriasis Foundation. Dr. Siegfried disclosed ties with AbbVie, Boehringer Ingelheim, Incyte, LEO Pharma, Novan, Novartis, Pierre Fabre, Pfizer, Regeneron, Sanofi Genzyme, UCB, and Verrica.

While the typical dose of methotrexate (MTX) for inflammatory disease in pediatric patients varies in published studies, the maximum dose is considered to be 1 mg/kg and not to exceed 25 mg/week. In addition, test doses are not necessary for pediatric patients starting low dose (1 mg/kg or less) MTX for inflammatory skin disease, and the onset of efficacy with MTX may take 8-16 weeks.

“Methotrexate is a cost-effective, readily accessible, well-tolerated, useful, and time-honored option for children with a spectrum of inflammatory skin diseases,” project cochair Elaine C. Siegfried, MD, professor of pediatrics and dermatology at Saint Louis University, told this news organization. “Although considered an ‘immune suppressant’ by some, it is more accurately classified as an immune modulator and has been widely used for more than 50 years, and remains the standard of care when administered at very high doses and intrathecally in children with acute lymphoblastic leukemia – a practice that supports safety. But many details that support optimized treatment are not widely appreciated.”
In their guidelines document, Dr. Siegfried and her 22 coauthors noted that Food and Drug Administration labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata. “Furthermore, some clinicians may be unfamiliar or uncomfortable prescribing medications off label for pediatric patients, causing delayed initiation, premature drug discontinuation, or use of less advantageous alternatives,” they wrote.
To address this unmet need, Dr. Siegfried and the other committee members used a modified Delphi process to reach agreement on recommendations related to five key topic areas: indications and contraindications, dosing, interactions with immunizations and medications, potential for and management of adverse effects, and monitoring needs. Consensus was predefined as at least 70% of participants rating a statement as 7-9 on the Likert scale. The effort to develop 46 recommendations has been a work in progress for almost 5 years, “somewhat delayed by the pandemic,” Dr. Siegfried, past president and director of the American Board of Dermatology, said in an interview. “But it remains relevant, despite the emergence of biologics and JAK inhibitors for treating inflammatory skin conditions in children. Although the mechanism-of-action of low-dose MTX is not clear, it may overlap with the newer small molecules.”
The guidelines contain several pearls to guide optimal dosing, including the following key points:
- MTX can be discontinued abruptly without adverse effects, other than the risk of disease worsening.
- Folic acid supplementation (starting at 1 mg/day, regardless of weight) is an effective approach to minimizing associated gastrointestinal adverse effects.
- Concomitant use of MTX and antibiotics (including trimethoprim-sulfamethoxazole) and NSAIDS are not contraindicated for most pediatric patients treated for inflammatory skin disease.
- Live virus vaccine boosters such as varicella-zoster virus (VZV) and measles, mumps, and rubella (MMR) are not contraindicated in patients taking MTX; there are insufficient data to make recommendations for or against primary immunization with MMR vaccine in patients taking MTX; inactivated vaccines should be given to patients taking MTX.
- Routine surveillance laboratory monitoring (i.e., CBC with differential, alanine transaminase, aspartate aminotransferase, creatinine) is recommended at baseline, after 1 month of treatment, and every 3-4 months thereafter.
- Transient transaminase elevation (≤ 3 upper limit normal for < 3 months) is not uncommon with low-dose MTX and does not usually require interruption of MTX. The most likely causes are concomitant viral infection, MTX dosing within 24 hours prior to phlebotomy, recent administration of other medications (such as acetaminophen), and/or recent alcohol consumption.
- Liver biopsy is not indicated for routine monitoring of pediatric patients taking low-dose MTX.
According to Dr. Siegfried, consensus of the committee members was lowest on the need for a test dose of MTX.
Overall, she said in the interview, helping to craft the guidelines caused her to reflect on how her approach to using MTX has evolved over the past 35 years, after treating “many hundreds” of patients. “I was gratified to confirm similar practice patterns among my colleagues,” she added.

What’s new in the new jaundice guidelines?
More than 15 years in the making, the revised AAP Clinical Practice Guideline Revision: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation was released in 2022. A key driving force for this revision was the expanded evidence base regarding monitoring and treatment of newborns 35 or more weeks’ gestation to prevent bilirubin encephalopathy and kernicterus.
Here, we summarize the highlights of the new guidelines and point out practical ways to incorporate these guidelines into daily practice.
What has changed?
If you are familiar with the previous guidelines (2004 or the 2009 update) for the management of newborn jaundice, you’ll note that the treatment graphs for phototherapy and exchange transfusion have been updated with new, slightly higher thresholds.
Bilirubin thresholds for starting phototherapy are about 2 mg/dL higher overall than indicated in previous iterations of the guidelines.
This change reflects new evidence that infants don’t typically develop bilirubin neurotoxicity until the total serum bilirubin (TSB) reaches levels well above the previous exchange transfusion threshold, justifying a narrow increase in the bilirubin level for starting phototherapy. Also, phototherapy treatment thresholds are now risk-adjusted, with separate curves for each gestational age from 35 weeks to > 38 weeks.
To find the applicable phototherapy threshold, use the infant’s gestational age (rounding down) and determine whether the infant has even a single neurotoxicity risk factor other than prematurity. Neurotoxicity risk factors include a low albumin level, isoimmune hemolytic disease, glucose-6-phosphate dehydrogenase (G6PD) deficiency, or other hemolytic conditions; sepsis; or any significant clinical instability in the previous 24 hours.
For example, a 384/7 weeks’ gestation newborn has a TSB of 12 mg/dL at 48 hours of age but no neurotoxicity risk factors. Using the graph Phototherapy Thresholds: No Hyperbilirubinemia Neurotoxicity Risk Factors, should the infant be placed under phototherapy at this time? (Answer: No. The threshold for starting phototherapy on this infant is approximately 16 mg/dL.)
When hyperbilirubinemia becomes a medical emergency
A new term, “escalation of care,” has been adopted to describe actions to take when the newborn’s TSB climbs to within 2 mg/dL of the exchange transfusion threshold – a medical emergency. Instructions on how to ensure intensive phototherapy, and when to initiate an urgent exchange transfusion, are given, including the critical need to maintain intensive phototherapy continuously during infant transport and admission to another facility.
Transcutaneous vs. serum bilirubin
Either a serum TSB or a transcutaneous bilirubin (TcB) should be measured in all infants between 24 and 48 hours after birth or before discharge if that occurs earlier. TcB measurements are valid and reliable when used as a screening test to identify infants who require a TSB measurement. Although the two tests are generally correlated, they are not identical, and treatment decisions should be based on TSB levels. A TSB should be obtained if the TcB exceeds or is within 3 mg/dL of the phototherapy treatment threshold, or if the TcB is ≥ 15 mg/dL.
Following up: When to check another bilirubin level
Prior to these new guidelines, the question of when to get the next bilirubin level was based on Vinod Bhutani, MD’s risk nomogram, which classified newborn bilirubin levels within high-, intermediate-, or low-risk zones for needing phototherapy. A bilirubin level in the high-risk zone indicated the need for earlier follow-up. These risk zones have been replaced with a more specific table that provides recommended postdischarge follow-up based on how close the newborn’s bilirubin level is to the hour-specific threshold for treatment. The closer the latest TSB or TcB level is to the newborn’s risk-based phototherapy threshold, the sooner the follow-up to check another bilirubin level will need to be.
Most infants discharged before 72 hours of age will need follow-up within 2 days. Newborns with TSB levels nearing the level for phototherapy (within 2 mg/dL or less) should remain in the hospital.
Five tips for using the new guidelines
Bilitool.org, a popular and useful app, has already been updated to reflect the changes in the new guidelines, making it easy to apply the new thresholds and create a follow-up plan for each patient.
The guidelines provide recommendations for when to check rebound bilirubin levels after stopping phototherapy (hint: babies with neurotoxic risk factors). A TcB device should not be used while the infant is being treated with phototherapy. However, a TcB can be measured once the baby has been off phototherapy for at least 24 hours.
If you have at least two bilirubin measurements, you can calculate the “rate of rise” in bilirubin level. A rapid rate of rise, which serves as a clinical indicator of hemolysis, is defined as ≥ 0.3 mg/dL per hour in the first 24 hours or ≥ 0.2 mg/dL per hour after the first 24 hours of life. This is especially helpful when hemolysis is suspected even if the newborn’s direct antibody test (DAT) is negative. In this scenario, the infant is considered to have a neurotoxic risk factor.
When you initiate phototherapy, be aware of the infant’s bilirubin level threshold for stopping phototherapy (2 mg/dL below the starting phototherapy threshold), as well as the threshold for escalation of care (2 mg/dL below the exchange transfusion threshold).
Because the thresholds for starting phototherapy and initiating exchange transfusion are slightly higher and specific to gestational age, clinicians can more confidently use less phototherapy.
Other guideline highlights
The neurotoxic risk factors and corresponding thresholds are important. If the newborn has one or more neurotoxic risk factors other than prematurity, the neurotoxic risk threshold graph should be used when assessing the need for treatment. Neurotoxic risk thresholds should also be used for newborns whose bilirubin levels continue rising on phototherapy.
The guidelines emphasize that G6PD is one of the most important causes of hazardous hyperbilirubinemia leading to kernicterus in the United States and worldwide. Overall, 13% of African American males and about 4% of African American females have G6PD deficiency.
Finally, the guidelines remind clinicians that an important way to reduce the chances that phototherapy will be needed is to encourage early and frequent feeding (8-12 times in 24 hours).
The AAP Clinical Practice Guideline Revision: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation contains a great deal more information, but these basic principles should allow practitioners to begin to incorporate these guidelines into daily practice.

CGM alarm fatigue in youth?
Teenagers with diabetes who use a continuous glucose monitor (CGM) employ a wide variety of alarm settings to alert them when their blood sugar may be too high or too low. But sometimes those thresholds generate too many alarms – which in turn might lead patients to ignore the devices, according to a study presented at the 2023 annual meeting of the Endocrine Society.
“These alarms alert people with diabetes and their caregivers of pending glycemic changes. However, little work has been done studying CGM alarm settings in pediatric clinical populations,” said Victoria Ochs, BS, a medical student at the Indiana University, Indianapolis, who helped conduct the study.
Ms. Ochs and colleagues analyzed 2 weeks of real-time CGM alarm settings from 150 children with diabetes treated at Indiana. Their average age was 14 years; 47% were female, 89% of were White, 9.5% were Black, and 1.5% were Asian. Approximately half the patients used insulin pumps (51%) in addition to the monitoring devices.
For both alarms that indicated blood sugar was too low or too high, settings among the children often varied widely from thresholds recommended by the University of Colorado’s Barbara Davis Center for Diabetes, Aurora. Those thresholds are 70 mg/dL of glucose for low and 180 mg/dL for high glucose. At Indiana, the median alert level for low was set to 74 mg/dL (range: 60-100), while the median for high was 242 mg/dL (range: 120-400).
“If we have it set at 100, what exactly is the purpose of that? Is it just to make you more anxious that you’re going to drop low at some point?” asked Cari Berget, MPH, RN, CDE, who specializes in pediatric diabetes at the University of Colorado, speaking of the low blood sugar alarm. Setting this alarm at 70 md/dL instead could lead to concrete action when it does go off – such as consuming carbohydrates to boost blood sugar, she said.
“Alarms should result in action most of the time,” said Ms. Berget, associate director of Colorado’s PANTHER program, which established the alarm thresholds used in the Indiana study. Alarm setting is not one-size-fits-all, Ms. Berget noted: Some people might want 70 mg/dL to warn of low blood sugar, whereas others prefer 75 or 80 mg/dL.
As for alerts about hyperglycemia, Ms. Berget said patients often exceed the high range of 180 mg/dL immediately after a meal. Ideally these sugars will subside on their own within 3 hours, a process aided by insulin shots or pumps. Setting a threshold for high blood sugar too low, such as 120 mg/dL, could result in ceaseless alarms even if the person is not at risk for harm.
“If you receive an alarm and there’s no action for you to take, then we need to change how we’re setting these alarms,” Ms. Berget said. She advised parents and children to be thoughtful about setting their CGM alarm thresholds to be most useful to them.
Ms. Ochs said in some cases families have CGM devices shipped directly to their homes and never consult with anyone about optimal alarm settings.
“It would be useful to talk to families about what baseline information they had,” Ms. Ochs told this news organization. “It would be nice to talk to diabetes educators, and I think it would be nice to talk to physicians.”
Ms. Ochs reports no relevant financial relationships. Ms. Berget has consulted for Dexcom and Insulet.

But sometimes those thresholds generate too many alarms – which in turn might lead patients to ignore the devices, according to a study presented at the 2023 annual meeting of the Endocrine Society.
“These alarms alert people with diabetes and their caregivers of pending glycemic changes. However, little work has been done studying CGM alarm settings in pediatric clinical populations,” said Victoria Ochs, BS, a medical student at the Indiana University, Indianapolis, who helped conduct the study.
Ms. Ochs and colleagues analyzed 2 weeks of real-time CGM alarm settings from 150 children with diabetes treated at Indiana. Their average age was 14 years; 47% were female, 89% of were White, 9.5% were Black, and 1.5% were Asian. Approximately half the patients used insulin pumps (51%) in addition to the monitoring devices.
For both alarms that indicated blood sugar was too low or too high, settings among the children often varied widely from thresholds recommended by the University of Colorado’s Barbara Davis Center for Diabetes, Aurora. Those thresholds are 70 mg/dL of glucose for low and 180 mg/dL for high glucose. At Indiana, the median alert level for low was set to 74 mg/dL (range: 60-100), while the median for high was 242 mg/dL (range: 120-400).
“If we have it set at 100, what exactly is the purpose of that? Is it just to make you more anxious that you’re going to drop low at some point?” asked Cari Berget, MPH, RN, CDE, who specializes in pediatric diabetes at the University of Colorado, speaking of the low blood sugar alarm. Setting this alarm at 70 md/dL instead could lead to concrete action when it does go off – such as consuming carbohydrates to boost blood sugar, she said.
“Alarms should result in action most of the time,” said Ms. Berget, associate director of Colorado’s PANTHER program, which established the alarm thresholds used in the Indiana study. Alarm setting is not one-size-fits-all, Ms. Berget noted: Some people might want 70 mg/dL to warn of low blood sugar, whereas others prefer 75 or 80 mg/dL.
As for alerts about hyperglycemia, Ms. Berget said patients often exceed the high range of 180 mg/dL immediately after a meal. Ideally these sugars will subside on their own within 3 hours, a process aided by insulin shots or pumps. Setting a threshold for high blood sugar too low, such as 120 mg/dL, could result in ceaseless alarms even if the person is not at risk for harm.
“If you receive an alarm and there’s no action for you to take, then we need to change how we’re setting these alarms,” Ms. Berget said. She advised parents and children to be thoughtful about setting their CGM alarm thresholds to be most useful to them.
Ms. Ochs said in some cases families have CGM devices shipped directly to their homes and never consult with anyone about optimal alarm settings.
“It would be useful to talk to families about what baseline information they had,” Ms. Ochs told this news organization. “It would be nice to talk to diabetes educators, and I think it would be nice to talk to physicians.”
Ms. Ochs reports no relevant financial relationships. Ms. Berget has consulted for Dexcom and Insulet.

Young girls, women are at high risk of iron deficiency: Study
, which can lead to fatigue and increase the risk of many health problems, according to a new study.
Researchers also found that 6 in every 100 of the girls and young women had extremely low iron levels, known as iron-deficiency anemia, which impacts the blood’s ability to carry oxygen throughout the body.
The findings suggest that current screening guidelines for iron levels in girls and women may be flawed, resulting in missed chances to get a simple blood test that can diagnose the easy-to-treat condition. Iron supplements are often prescribed as a treatment.
The study was published in JAMA and included 12 years of data for a total of nearly 3,500 girls and women aged 12-21 years.
In addition to shortness of breath and fatigue, other symptoms of iron deficiency anemia are:
- Pale skin
- Cold hands and feet
- Feeling dizzy or lightheaded
- Unusual cravings for nonfood items such as ice, dirt, or paper.
The Cleveland Clinic says the most common causes of iron-deficiency anemia are those that involve blood loss, including heavy menstrual periods. The body gets iron from food, and not getting enough iron from food, as can happen from eating a vegan or vegetarian diet, can also lead to deficiency.
In this latest study, researchers found that young women and girls’ likelihood to have iron deficiency or iron-deficiency anemia were significantly linked to race and ethnicity, poverty status, access to sufficient or quality food (also called food insecurity), and body mass index. Black and Hispanic girls and women were more likely to have iron level problems, compared with White girls and women. Black girls and women were four times more likely to have iron-deficiency anemia, compared with White girls and women.
The authors did not discuss potential causes and suggested further study is needed to identify risk factors of iron deficiency in girls and young women.

New AAP framework seeks to help pediatricians monitor premature babies
About 1 in 10 babies in the United States are born before full term. Even when they are discharged from neonatal intensive care units (NICUs), these babies are still at risk for conditions like cerebral palsy, autism spectrum disorder, deafness, and severe hearing loss.
The framework, published in Pediatrics, consolidates existing research into a guide for busy pediatricians to categorize patients as very high risk, high risk, or moderate-low risk for neurodevelopmental disabilities. The guidance also lists key identifiers to help providers flag issues early, such as asymmetry of hand use.
Beth Ellen Davis, MD, MPH, a framework author, said the goal is to help pediatricians determine what surveillance and screening they can conduct to promote positive health outcomes.
Dr. Davis said she wished she had this guidance on caring for children who were born prematurely during her 10 years as a general pediatrician in the U.S. Army Medical Corps.
“I didn’t know what I was supposed to do differently with [the former NICU babies],” said Dr. Davis, a professor in the division of neurodevelopmental behavioral pediatrics at the University of Virginia, Charlottesville.
For instance, babies born earlier than 28 weeks who have hypoxic ischemic encephalopathy or retinopathy of prematurity requiring surgery or intervention are classified as very high risk for the adverse outcomes, including intellectual disability.
The authors recommend follow-up and surveillance based on risk level at roughly 9-month intervals until around age 5. Each visit includes assessing for developmental milestones, like walking by 18 months or noting atypical pencil grasp at age 3.
Kendell German, MD, a neonatologist at University of Washington Medical Center, Seattle, and Seattle Children’s Hospital and a coauthor of the publication, said the tool will hopefully ensure that children are referred earlier to specialists.
“As neonatologists, we think about risk factors, but further out from birth, some of those things may be missed – particularly when we start thinking about kids who are transitioning in school and thinking about learning disabilities,” Dr. German said.
The guidance also outlines when pediatricians should – or should not – reassure families that an intellectual disability won’t develop. According to the authors, by age 3, the majority of children who have severe developmental disabilities will have been diagnosed.
“Some say you have to always keep suspicion out there for families of children who are born premature,” Dr. Davis said. “But we feel that after a period of time of monitoring and a child meeting their milestones, we can reassure parents that it is very unlikely their child will develop some of these severe developmental disabilities.”
Douglas Vanderbilt, MD, MS, chief of the developmental-behavioral pediatrics division and director of newborn and infant follow-up program at Children’s Hospital Los Angeles, said that general pediatricians and family practice clinicians may face barriers to implementation such as not having enough time to screen patients or difficulty collaborating with specialists.
But, “whatever we can do to articulate, educate, and facilitate a capacity within general pediatrics to improve training is a really good thing,” said Dr. Vanderbilt, who was not involved with the guidance.
The authors also highlighted lower-severity conditions that can result from prematurity, such as language and speech disorders, developmental coordination disorders, ADHD, and visual motor integration problems.
“Those of us in the medical field can be quite focused on the most severe disabilities that are possible,” said Andrea Duncan, MD, MSc, director of the neonatal follow-up program at the Children’s Hospital of Philadelphia, who was not associated with the report. But, “most of the disabilities we see in follow-up are more subtle or milder but can have a very significant impact on school function, participation, and the overall quality of a child’s life.
Dr. Duncan said the framework doesn’t entirely put the onus on primary care clinicians, but helps stratify risk and indicates when referrals to specialists may be appropriate.
“The importance of partnerships really comes through,” with specialties like neurology, audiology, and developmental behavioral pediatrics, Dr. Duncan said. “As long as those partnerships are made and families have access to services, implementation should be relatively easy.”
The authors of the report declared no relevant financial relationships. Dr. Vanderbilt is a consultant for a startup called Develo. He has no equity in the company.

Limiting social media use in youths brings challenges, benefits
Amelia Kennedy, 19, of Royersford, Pa., a point guard on the Catholic University of America, Washington, basketball team who will begin her sophomore year in the fall, uses TikTok, Snapchat, Instagram, and YouTube regularly.
How regularly? She estimates 7 hours a day and about 9 on weekends. She’s aware of the time-wasting potential. “If my mom says, ‘Do dishes,’ and I say, ‘5 more minutes,’ it can be longer,’’ she said.
Now imagine the challenge of cutting that 7 or 9 hours a day of social media use down to 30 minutes.
A very tall order, considering a 2022 Pew Research Center survey of more than 1,300 teens found 35% are “nearly constantly” on at least one of the top five social media platforms: YouTube, TikTok, Instagram, Snapchat, and Facebook.
Researchers from Iowa State University, Ames, recently took on that daunting challenge, limiting a group of students to only 30 minutes of social media a day to see what happens. Two weeks into the study, the students reported improvement in psychological well-being and other important measures, including sleep quality, compared with a control group assigned to continue using social media as usual.
And the dreaded FOMO, or fear of missing out, didn’t happen, the researchers said. At the end, the students were rethinking their social media use and feeling positive about it.
As social media becomes more common and youth mental health more endangered, experts are sounding the alarm. In late May, U.S. Surgeon General Vivek Murthy, MD, issued an advisory on social media and youth mental health, calling for tech companies to do better, policymakers to strengthen safety, and researchers to get more information, among other actions.
After that, the Biden administration took actions including the launch of a task force on kids’ online health and safety. The American Psychological Association has issued recommendations on social media use in youths. And the Social Media Victims Law Center in Seattle has sued numerous social media companies for online activity resulting in death and other tragedies.
While experts acknowledge that much more research is needed to sort out how to balance social media’s risks and benefits to preserve youth mental health and prevent such disasters, the new Iowa State study, as well as other recent research, suggests that
Goal: 30 minutes a day
In the Iowa State study, 230 undergraduate students were assigned to one of two groups, with 99 in the 30-minute-a-day social media use group and 131 in the “usual” or control group, which made no changes. For those in the intervention group, “we sent a daily reminder email,” said Ella Faulhaber, a PhD candidate at Iowa State and the study’s lead author. It simply reminded them to limit social medial use to the 30-minute maximum.
At the study start and end, all participants provided a screenshot of their weekly social media usage time. The researchers gave both groups a battery of tests to assess anxiety, depression, loneliness, fear of missing out, and negative and positive feelings.
“By limiting their social media time, that resulted in less anxiety, less depression, less FOMO, fewer negative emotions, and greater positive emotions,” said Douglas Gentile, PhD, a distinguished professor of psychology at Iowa State and a study coauthor. “We know that it is the limiting [of] the social media that is causing that.”
Ms. Faulhaber recalled one participant who mentioned having trouble at first adjusting to the 30-minute time frame, but once sleep improved, it was easier to stick to that guidance. Another who gave up phone use at bedtime found: “Instead of looking at my phone, it was much easier to go straight to bed.”
Sleep improvements, of course, affect many parts of physical and mental health, Dr. Gentile said. And the study also showed that even with reduced screen time, “we can still get the benefit of being connected.” Those who didn’t make the 30-minute mark, but cut back, got benefits, too, the researchers said.
‘Youth are aware’
Self-monitoring works, agreed Jane Harness, DO, an adjunct clinical assistant professor of psychiatry at the University of Michigan, Ann Arbor, because “having that insight is often the first step.”
In a study she conducted, Dr. Harness aimed to gather youths’ insights about how their social media use affected them. With her colleagues, she asked more than 1,100 youths, aged 14-24, what advice they would give to those new to social media, if they ever felt they needed to change social media habits, and if they have deleted or considered deleting social media accounts.
From the 871 responses, Harness found that youths were especially concerned about safety online, that most had thought about deleting a social media app and some had, and that youths were more likely to say they wanted to change the amount of time spent on social media, compared with the content they view.
“Users responded with great advice for each other,” she said. “Safety was brought up,” with users reminding others to keep accounts private and to be aware of location tracking links and content that seems to promote eating disorders, suicide, and other harms.
In the study report, Dr. Harness concluded: “Youth are aware of ways in which social media could be negatively impacting them and they have employed methods to modulate their use because of this awareness.”
Less FOMO, less anxiety
In an earlier study, University of Pennsylvania, Philadelphia, researchers had 143 college students self-monitor social media for a week, then randomly assigned them either to a group told to limit Facebook, Instagram, and Snapchat use to 10 minutes per platform, per day, or to a group told to use social media as usual for 3 weeks.
At the end of the study, the researchers evaluated both groups and found “significant reductions in loneliness and depression over 3 weeks’’ in the limited-use group, compared with the usual-use group, according to study researcher Melissa G. Hunt, PhD, associate director of clinical training at the University of Pennsylvania.
And both groups showed declines in anxiety and fear of missing out, suggesting a benefit tied to self-monitoring itself, she said.
While Dr. Hunt’s study focused on 30 minutes a day, she said “about an hour a day seems to be the sweet spot for maximizing the positive effects of connecting, but limiting the negative effects of social media use.”
She also suggested that smartphones have no place in middle or high school classrooms. Instead, they should be on lockdown during classes.
“Parents need to set real limits of cellphone use during meals and in bedrooms,” Dr. Hunt said. At mealtime, for instance, all phones should be absent from the table. And after 10 p.m., “all family phones remain in the kitchen.”
Be ‘more mindful’
These recent study findings about self-monitoring and limiting social media time may not work the same for everyone, especially among those who aren’t as motivated, said psychiatrist Elizabeth Ortiz-Schwartz, MD, team lead for the adolescent inpatient unit at Silver Hill Hospital in New Canaan, Conn.
But “the bigger take-home piece is that being intentional and attempting to decrease the use in these individuals, even if they were not always successful, was clearly beneficial,” she said.
As we await clearer guidelines about what is the “right” amount of use in terms of social media content and time, Dr. Ortiz-Schwartz said, “becoming more mindful and aware of the risks and benefits can hopefully help individuals become more mindful and deliberate about its use.”
Real-world strategies
Max Schwandt, 23, is an outlier, but a happy one. He works as a sales clerk at a Los Angeles–area recreational gear shop, and he uses no social media. Why not? “It takes up too much time,” he explained. As simple as that.
But for many other teens and young adults, the struggle to stay off social media is real.
Amelia Kennedy, the Catholic University of America student, is trying to reduce her screen time. One way is to track it on her phone. These days, her summer job at a restaurant serving breakfast gets her up early. “If I have to work, I still go on my phone, but not that long.” And once at work, she only has time for quick checks between work responsibilities. “I definitely am more productive,” she said about days when she has work.
Last December, Lauren Young, 25, whose father was a researcher on the Iowa State study, was finishing law school at Georgetown University, Washington, and decided to take a break from social media for the entire month. “I can’t say I was always successful in avoiding it,” she said. But cutting down greatly “made me a lot more present in my day-to-day life, and it was easier to concentrate.”
She could even get through a meal, out with friends, without her phone, keeping it in her purse. That was a definite change from the norm. “I noticed I would go out to dinner and the standard for people my age is having the phone on the table. If you are being polite, you turn it over.”
During her social media “blackout,” Ms. Young had deleted TikTok, Instagram, and Facebook apps. Then, when she graduated, she had to reinstall to post a picture. But now, she is back to minimal social media use.
“I’m studying for the bar, so it’s kind of necessary, but it always makes me happier.” She figures she can always text family and friends if necessary, instead of posting. “I felt for a while I was missing out on things, but not now,” she said.
Others, including Sarah Goldstein, 22, of Chatsworth, Calif., a supermarket courtesy clerk who is thinking of returning to college, said she has developed a healthier attitude toward social media as she has gotten older.
“In middle and early high school, I would see parties, things I wasn’t invited to, on Snapchat and Instagram.” While she realized there could be legitimate reasons for not being included, she said it was easy to internalize those feelings of being left out.

Amelia Kennedy, 19, of Royersford, Pa., a point guard on the Catholic University of America, Washington, basketball team who will begin her sophomore year in the fall, uses TikTok, Snapchat, Instagram, and YouTube regularly.
How regularly? She estimates 7 hours a day and about 9 on weekends. She’s aware of the time-wasting potential. “If my mom says, ‘Do dishes,’ and I say, ‘5 more minutes,’ it can be longer,’’ she said.
Now imagine the challenge of cutting that 7 or 9 hours a day of social media use down to 30 minutes.
A very tall order, considering a 2022 Pew Research Center survey of more than 1,300 teens found 35% are “nearly constantly” on at least one of the top five social media platforms: YouTube, TikTok, Instagram, Snapchat, and Facebook.
Researchers from Iowa State University, Ames, recently took on that daunting challenge, limiting a group of students to only 30 minutes of social media a day to see what happens. Two weeks into the study, the students reported improvement in psychological well-being and other important measures, including sleep quality, compared with a control group assigned to continue using social media as usual.
And the dreaded FOMO, or fear of missing out, didn’t happen, the researchers said. At the end, the students were rethinking their social media use and feeling positive about it.
As social media becomes more common and youth mental health more endangered, experts are sounding the alarm. In late May, U.S. Surgeon General Vivek Murthy, MD, issued an advisory on social media and youth mental health, calling for tech companies to do better, policymakers to strengthen safety, and researchers to get more information, among other actions.
After that, the Biden administration took actions including the launch of a task force on kids’ online health and safety. The American Psychological Association has issued recommendations on social media use in youths. And the Social Media Victims Law Center in Seattle has sued numerous social media companies for online activity resulting in death and other tragedies.
While experts acknowledge that much more research is needed to sort out how to balance social media’s risks and benefits to preserve youth mental health and prevent such disasters, the new Iowa State study, as well as other recent research, suggests that
Goal: 30 minutes a day
In the Iowa State study, 230 undergraduate students were assigned to one of two groups, with 99 in the 30-minute-a-day social media use group and 131 in the “usual” or control group, which made no changes. For those in the intervention group, “we sent a daily reminder email,” said Ella Faulhaber, a PhD candidate at Iowa State and the study’s lead author. It simply reminded them to limit social medial use to the 30-minute maximum.
At the study start and end, all participants provided a screenshot of their weekly social media usage time. The researchers gave both groups a battery of tests to assess anxiety, depression, loneliness, fear of missing out, and negative and positive feelings.
“By limiting their social media time, that resulted in less anxiety, less depression, less FOMO, fewer negative emotions, and greater positive emotions,” said Douglas Gentile, PhD, a distinguished professor of psychology at Iowa State and a study coauthor. “We know that it is the limiting [of] the social media that is causing that.”
Ms. Faulhaber recalled one participant who mentioned having trouble at first adjusting to the 30-minute time frame, but once sleep improved, it was easier to stick to that guidance. Another who gave up phone use at bedtime found: “Instead of looking at my phone, it was much easier to go straight to bed.”
Sleep improvements, of course, affect many parts of physical and mental health, Dr. Gentile said. And the study also showed that even with reduced screen time, “we can still get the benefit of being connected.” Those who didn’t make the 30-minute mark, but cut back, got benefits, too, the researchers said.
‘Youth are aware’
Self-monitoring works, agreed Jane Harness, DO, an adjunct clinical assistant professor of psychiatry at the University of Michigan, Ann Arbor, because “having that insight is often the first step.”
In a study she conducted, Dr. Harness aimed to gather youths’ insights about how their social media use affected them. With her colleagues, she asked more than 1,100 youths, aged 14-24, what advice they would give to those new to social media, if they ever felt they needed to change social media habits, and if they have deleted or considered deleting social media accounts.
From the 871 responses, Harness found that youths were especially concerned about safety online, that most had thought about deleting a social media app and some had, and that youths were more likely to say they wanted to change the amount of time spent on social media, compared with the content they view.
“Users responded with great advice for each other,” she said. “Safety was brought up,” with users reminding others to keep accounts private and to be aware of location tracking links and content that seems to promote eating disorders, suicide, and other harms.
In the study report, Dr. Harness concluded: “Youth are aware of ways in which social media could be negatively impacting them and they have employed methods to modulate their use because of this awareness.”
Less FOMO, less anxiety
In an earlier study, University of Pennsylvania, Philadelphia, researchers had 143 college students self-monitor social media for a week, then randomly assigned them either to a group told to limit Facebook, Instagram, and Snapchat use to 10 minutes per platform, per day, or to a group told to use social media as usual for 3 weeks.
At the end of the study, the researchers evaluated both groups and found “significant reductions in loneliness and depression over 3 weeks’’ in the limited-use group, compared with the usual-use group, according to study researcher Melissa G. Hunt, PhD, associate director of clinical training at the University of Pennsylvania.
And both groups showed declines in anxiety and fear of missing out, suggesting a benefit tied to self-monitoring itself, she said.
While Dr. Hunt’s study focused on 30 minutes a day, she said “about an hour a day seems to be the sweet spot for maximizing the positive effects of connecting, but limiting the negative effects of social media use.”
She also suggested that smartphones have no place in middle or high school classrooms. Instead, they should be on lockdown during classes.
“Parents need to set real limits of cellphone use during meals and in bedrooms,” Dr. Hunt said. At mealtime, for instance, all phones should be absent from the table. And after 10 p.m., “all family phones remain in the kitchen.”
Be ‘more mindful’
These recent study findings about self-monitoring and limiting social media time may not work the same for everyone, especially among those who aren’t as motivated, said psychiatrist Elizabeth Ortiz-Schwartz, MD, team lead for the adolescent inpatient unit at Silver Hill Hospital in New Canaan, Conn.
But “the bigger take-home piece is that being intentional and attempting to decrease the use in these individuals, even if they were not always successful, was clearly beneficial,” she said.
As we await clearer guidelines about what is the “right” amount of use in terms of social media content and time, Dr. Ortiz-Schwartz said, “becoming more mindful and aware of the risks and benefits can hopefully help individuals become more mindful and deliberate about its use.”
Real-world strategies
Max Schwandt, 23, is an outlier, but a happy one. He works as a sales clerk at a Los Angeles–area recreational gear shop, and he uses no social media. Why not? “It takes up too much time,” he explained. As simple as that.
But for many other teens and young adults, the struggle to stay off social media is real.
Amelia Kennedy, the Catholic University of America student, is trying to reduce her screen time. One way is to track it on her phone. These days, her summer job at a restaurant serving breakfast gets her up early. “If I have to work, I still go on my phone, but not that long.” And once at work, she only has time for quick checks between work responsibilities. “I definitely am more productive,” she said about days when she has work.
Last December, Lauren Young, 25, whose father was a researcher on the Iowa State study, was finishing law school at Georgetown University, Washington, and decided to take a break from social media for the entire month. “I can’t say I was always successful in avoiding it,” she said. But cutting down greatly “made me a lot more present in my day-to-day life, and it was easier to concentrate.”
She could even get through a meal, out with friends, without her phone, keeping it in her purse. That was a definite change from the norm. “I noticed I would go out to dinner and the standard for people my age is having the phone on the table. If you are being polite, you turn it over.”
During her social media “blackout,” Ms. Young had deleted TikTok, Instagram, and Facebook apps. Then, when she graduated, she had to reinstall to post a picture. But now, she is back to minimal social media use.
“I’m studying for the bar, so it’s kind of necessary, but it always makes me happier.” She figures she can always text family and friends if necessary, instead of posting. “I felt for a while I was missing out on things, but not now,” she said.
Others, including Sarah Goldstein, 22, of Chatsworth, Calif., a supermarket courtesy clerk who is thinking of returning to college, said she has developed a healthier attitude toward social media as she has gotten older.
“In middle and early high school, I would see parties, things I wasn’t invited to, on Snapchat and Instagram.” While she realized there could be legitimate reasons for not being included, she said it was easy to internalize those feelings of being left out.
These days, she said she doesn’t let it affect her mental health that way. She enjoys social media – especially TikTok and Instagram – for its benefits. “It kills time, gives you something to watch, can make you laugh and feel like you have a connection with other people.”

HPV rates skyrocket despite safe, effective vaccine
oropharyngeal cancer, which can affect the back of the throat, tonsils, and tongue.
An epidemic of sexually transmitted HPV is now swirling around the United States and the United Kingdom, with some serious cases leading toHPV is the leading cause (70%) of this oropharyngeal cancer, according to the CDC. It is the most common sexually transmitted disease in the nation, and around 3.6% of women and 10% of men report oral HPV specifically. But over the past decade, oropharyngeal cases have been steadily falling a little under 4% and 2%, respectively, according to the National Cancer Institute.
HPV is often undetectable and can clear up within a few months. But unfortunately for some, serious disease, such as throat cancer, can develop.
Studies show the HPV vaccine to be extremely effective in lowering sexually transmitted HPV cases. Yet, only 54.5% of young people aged 13-15 have taken the recommended two to three doses, according to the National Cancer Institute.
Why aren’t more young people taking the vaccine?
Low public awareness of the dangers of HPV may be behind young people’s poor vaccination rates, according to Teresa Lee, MD, of the Fox Chase Cancer Center in Philadelphia. “For example, while the link with head and neck cancers has been well-studied, the FDA labeling was not changed to reflect this as an indication until 2020,” she said.
Other reasons can include one’s socioeconomic background, poor health literacy, cultural or religious stigmas around vaccines, and lack of quality, low-cost health care, says Emmanuel Aguh, MD, a board-certified family medicine physician. “Some individuals and families are still resistant to vaccines and the noted lack of uptake.”
Doctors and other health care professionals should also be sure to tell patients of all ages about the risks of HPV infection and how well the vaccine works, Dr. Lee said. “Not everyone who is now eligible may have been offered the vaccine as a child, and the first time young adults may receive counseling on this subject may not be until they are entering a very busy period of their lives with many responsibilities – when it may be hard to fit in things like health maintenance.”
How safe is the HPV vaccine?
The Food and Drug Administration and Centers for Disease Control and Prevention have studied the HPV vaccine for years to find out how safe it is and how well it works, Dr. Aguh said. No major side effects have been reported, and the most common side effect is soreness where you get the shot (which is normal after most vaccines). Some dizziness and fainting in adolescents can also occur, so young people are usually asked to sit or lie down during the shot and for 15 minutes afterward, he said.
“Serious adverse events have not been reported at higher rates than expected following HPV vaccination, meaning there is no clear evidence they are related to the vaccine,” Dr. Lee said. “The vaccine is highly effective in decreasing rates of detectable infection with the high-risk HPV strains responsible for HPV-associated cancers.”
The HPV vaccine is largely recommended for people aged 9-26, and sometimes up to age 45, depending on the individual, Dr. Aguh said. If you are over 26, talk to your doctor about whether you should consider getting the vaccine.
“It is usually given in two doses for complete protection if taken before the 15th birthday,” Dr. Aguh said. “If taken afterward, or in those with a weak immune system, they might require three doses to be fully protected.”
The vaccine produces antibodies that can stop HPV from infecting cells and lowers your chances of catching an HPV-related cancer, such as throat cancer or cancer of the cervix, he said.
While the vaccine is not guaranteed to protect you from the more than 100 strains of HPV, it can protect you from HPV 16 and HPV 18 – two high-risk strains that cause around 70% of cervical cancers.
What is fueling the rise of HPV cases?
A misconception that oral sex is somehow a “safe and risk-free” alternative to anal or vaginal sex could be one reason, Dr. Aguh said.
“It is important to know that, with oral sex, you are exposed to many of the risks associated with vaginal intercourse, especially if you do not take any measures to protect yourself and/or your partner,” Dr. Aguh said. “[With oral sex] it is possible to end up contracting an infection like chlamydia, gonorrhea, and even HPV, leading to an increased risk of HPV-associated oropharyngeal cancers.”
A lack of public awareness of what can cause throat cancer could also explain this phenomenon. The number of people you have oral sex with, along with the age you begin sexual activity, can greatly determine your risk of the disease, according to Dr. Lee. She echoes a report by Hisham Mehanna, PhD, in The Conversation.
“For oropharyngeal cancer, the main risk factor is the number of lifetime sexual partners, especially oral sex,” wrote Dr. Mehanna, a professor at the Institute of Cancer and Genomic Sciences at the University of Birmingham (England). “Those with six or more lifetime oral-sex partners are 8.5 times more likely to develop oropharyngeal cancer than those who do not practice oral sex.”
What are symptoms of oropharyngeal cancer?
Labored breathing or swallowing, a cough that won’t go away, and crackling or hoarseness of your voice could all be signs of throat cancer. Other symptoms include earaches, swelling of the head or neck, and enlarged lymph nodes, among others, Dr. Aguh said.
“The signs and symptoms of HPV-related throat cancers can be difficult to identify and recognize, as they can be vague and are also associated with other medical conditions. Sometimes, there are no signs at all, or they are not easily noticeable due to the location,” he said.
You should go see your doctor if you have any of these ailments for an extended period.
How to reduce your risk
In addition to having six or more oral-sex partners, smoking and drinking heavily could also raise your risk of throat cancer, said Dr. Lee. Proper dental health – like seeing your dentist regularly and practicing proper oral hygiene – can also shave your risk.
“[Good dental health] can help not just with head and neck cancer risk, but with many other inflammation-related diseases,” Dr. Lee said.
Using dental dams and condoms can also be a good method of protection, Dr. Aguh said. A dental dam is a stretchy sheet of latex, or polyurethane plastic, in the shape of a square that is made for blocking body fluid to lower your risk of contracting an STD via oral sex.
Keep in mind: Even with these protections, make sure you and your partner discuss each other’s sexual history, any prior or current STDs and their preferred protection from STDs, said Dr. Aguh.
If you or your partner is being treated for an STD, consider opting out of oral sex and consulting a doctor.
The HPV vaccine is another common method of protection. The shot is “approved for prevention of nine of the most high-risk strains of HPV,” or those that are most commonly linked to cancer, according to Dr. Lee. The vaccine “reduces the frequency of infection” with these viruses, which can ultimately lower the risk of cancers linked to HPV, including cervical, anal, and vulvar and vaginal cancers, she said.
“The best time to receive treatment for prevention of disease is prior to onset of sexual intercourse,” said Dr. Lee.
To get your HPV vaccine, head to your family doctor, school- or community-based health center, or state health department, suggests the CDC.

But over the past decade, oropharyngeal cases have been steadily falling a little under 4% and 2%, respectively, according to the National Cancer Institute.
HPV is often undetectable and can clear up within a few months. But unfortunately for some, serious disease, such as throat cancer, can develop.
Studies show the HPV vaccine to be extremely effective in lowering sexually transmitted HPV cases. Yet, only 54.5% of young people aged 13-15 have taken the recommended two to three doses, according to the National Cancer Institute.
Why aren’t more young people taking the vaccine?
Low public awareness of the dangers of HPV may be behind young people’s poor vaccination rates, according to Teresa Lee, MD, of the Fox Chase Cancer Center in Philadelphia. “For example, while the link with head and neck cancers has been well-studied, the FDA labeling was not changed to reflect this as an indication until 2020,” she said.
Other reasons can include one’s socioeconomic background, poor health literacy, cultural or religious stigmas around vaccines, and lack of quality, low-cost health care, says Emmanuel Aguh, MD, a board-certified family medicine physician. “Some individuals and families are still resistant to vaccines and the noted lack of uptake.”
Doctors and other health care professionals should also be sure to tell patients of all ages about the risks of HPV infection and how well the vaccine works, Dr. Lee said. “Not everyone who is now eligible may have been offered the vaccine as a child, and the first time young adults may receive counseling on this subject may not be until they are entering a very busy period of their lives with many responsibilities – when it may be hard to fit in things like health maintenance.”
How safe is the HPV vaccine?
The Food and Drug Administration and Centers for Disease Control and Prevention have studied the HPV vaccine for years to find out how safe it is and how well it works, Dr. Aguh said. No major side effects have been reported, and the most common side effect is soreness where you get the shot (which is normal after most vaccines). Some dizziness and fainting in adolescents can also occur, so young people are usually asked to sit or lie down during the shot and for 15 minutes afterward, he said.
“Serious adverse events have not been reported at higher rates than expected following HPV vaccination, meaning there is no clear evidence they are related to the vaccine,” Dr. Lee said. “The vaccine is highly effective in decreasing rates of detectable infection with the high-risk HPV strains responsible for HPV-associated cancers.”
The HPV vaccine is largely recommended for people aged 9-26, and sometimes up to age 45, depending on the individual, Dr. Aguh said. If you are over 26, talk to your doctor about whether you should consider getting the vaccine.
“It is usually given in two doses for complete protection if taken before the 15th birthday,” Dr. Aguh said. “If taken afterward, or in those with a weak immune system, they might require three doses to be fully protected.”
The vaccine produces antibodies that can stop HPV from infecting cells and lowers your chances of catching an HPV-related cancer, such as throat cancer or cancer of the cervix, he said.
While the vaccine is not guaranteed to protect you from the more than 100 strains of HPV, it can protect you from HPV 16 and HPV 18 – two high-risk strains that cause around 70% of cervical cancers.
What is fueling the rise of HPV cases?
A misconception that oral sex is somehow a “safe and risk-free” alternative to anal or vaginal sex could be one reason, Dr. Aguh said.
“It is important to know that, with oral sex, you are exposed to many of the risks associated with vaginal intercourse, especially if you do not take any measures to protect yourself and/or your partner,” Dr. Aguh said. “[With oral sex] it is possible to end up contracting an infection like chlamydia, gonorrhea, and even HPV, leading to an increased risk of HPV-associated oropharyngeal cancers.”
A lack of public awareness of what can cause throat cancer could also explain this phenomenon. The number of people you have oral sex with, along with the age you begin sexual activity, can greatly determine your risk of the disease, according to Dr. Lee. She echoes a report by Hisham Mehanna, PhD, in The Conversation.
“For oropharyngeal cancer, the main risk factor is the number of lifetime sexual partners, especially oral sex,” wrote Dr. Mehanna, a professor at the Institute of Cancer and Genomic Sciences at the University of Birmingham (England). “Those with six or more lifetime oral-sex partners are 8.5 times more likely to develop oropharyngeal cancer than those who do not practice oral sex.”
What are symptoms of oropharyngeal cancer?
Labored breathing or swallowing, a cough that won’t go away, and crackling or hoarseness of your voice could all be signs of throat cancer. Other symptoms include earaches, swelling of the head or neck, and enlarged lymph nodes, among others, Dr. Aguh said.
“The signs and symptoms of HPV-related throat cancers can be difficult to identify and recognize, as they can be vague and are also associated with other medical conditions. Sometimes, there are no signs at all, or they are not easily noticeable due to the location,” he said.
You should go see your doctor if you have any of these ailments for an extended period.
How to reduce your risk
In addition to having six or more oral-sex partners, smoking and drinking heavily could also raise your risk of throat cancer, said Dr. Lee. Proper dental health – like seeing your dentist regularly and practicing proper oral hygiene – can also shave your risk.
“[Good dental health] can help not just with head and neck cancer risk, but with many other inflammation-related diseases,” Dr. Lee said.
Using dental dams and condoms can also be a good method of protection, Dr. Aguh said. A dental dam is a stretchy sheet of latex, or polyurethane plastic, in the shape of a square that is made for blocking body fluid to lower your risk of contracting an STD via oral sex.
Keep in mind: Even with these protections, make sure you and your partner discuss each other’s sexual history, any prior or current STDs and their preferred protection from STDs, said Dr. Aguh.
If you or your partner is being treated for an STD, consider opting out of oral sex and consulting a doctor.
The HPV vaccine is another common method of protection. The shot is “approved for prevention of nine of the most high-risk strains of HPV,” or those that are most commonly linked to cancer, according to Dr. Lee. The vaccine “reduces the frequency of infection” with these viruses, which can ultimately lower the risk of cancers linked to HPV, including cervical, anal, and vulvar and vaginal cancers, she said.
“The best time to receive treatment for prevention of disease is prior to onset of sexual intercourse,” said Dr. Lee.
To get your HPV vaccine, head to your family doctor, school- or community-based health center, or state health department, suggests the CDC.

Vaginal microbiota transfer may affect neurodevelopment in cesarean infants
Previous studies have shown that gut microbiota in infancy could affect neurodevelopment, and infants delivered by cesarean are not exposed to potentially helpful microbes acquired by infants during vaginal delivery, wrote Lepeng Zhou, MD, of Southern Medical University, Guangdong, China, and colleagues.
“Infants delivered by C-section start life with very different bacteria than those born vaginally,” corresponding author Jose Clemente, PhD, of Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Because this is the first time the newborn is exposed to microbes, we and others have hypothesized for some time that this ‘first encounter’ might be significant to shape the development of the baby,” he said.
“A few years ago, we demonstrated that it is possible to change the microbiome of C-section–delivered infants using an intervention that makes their microbiome more similar to that of a vaginally-delivered infant,” Dr. Clemente told this news organization. “In this study just published, we show that this procedure not only changes the microbiome of C-section infants, but it also modifies a health outcome (in this case, neurodevelopment). This is highly significant because it opens the way to reduce the risk that C-section infants have for certain conditions through a very simple microbial intervention,” he said.
‘Significantly higher’ ASQ-3 scores
In the current study, published in Cell Host & Microbe, the researchers examined the impact of vaginal microbiota transfer (VMT) on the neurodevelopment of cesarean-delivered infants. They randomized 35 women scheduled for cesarean delivery with a single infant to VMT and 41 to a control intervention of saline gauze for their infants immediately after delivery.
The primary outcome of infant neurodevelopment was assessed using the Ages and Stages Questionnaire (ASQ-3) score at 6 months. The researchers also collected fecal samples and assessed safety outcomes for the infants at 3, 7, 30, and 42 days after birth. The final analysis comprised 32 infants in the VMT group and 36 in the control group. The mean age of the mothers was 32 years; the mean gestational age of the infants was 39 weeks, but the difference was significant and slightly less in the VMT group compared with the controls (38.38 weeks vs. 39.13 weeks, P = .007). A group of 33 vaginally-delivered infants (VD) underwent ASQ-3 testing to serve as a reference group.
At 6 months, ASQ-3 scores were significantly higher (10.09%, P = .014) with VMT compared with controls, and the difference remained significant after adjustment for multiple factors including gestational age.
ASQ-3 total scores at 6 months were not significantly different between the VMT group and the VD reference group (mean difference of 8.84 VMT to VD, P = .346); scores between these groups also were similar at 3 months (mean difference of –1.48 VMT to VD, P = .900) and no significant differences appeared in ASQ-3 subdomains between these groups at either time period.
An examination of gut metabolites in stool showed significant differences in fecal metabolites and metabolic function, signs of gut microbiota maturation, the researchers noted.
“Interestingly, all the genera and metabolites that exhibited positive correlations with neurodevelopmental scores were upregulated in the VMT group, whereas the only negative correlation of Klebsiella was downregulated, indicating that VMT may impact neurodevelopment through the modulation of specific gut microbial genera and metabolites,” the researchers wrote.
No serious adverse events occurred in either group during the study period. Nine adverse events were reported; 4 in the VMT group and 5 in the control group. The most common AEs were mild skin disorders, including papules, pustules, and erythema.
The findings were limited by several factors including the potential for transfer not only of vaginal microbiota, but also vaginal metabolites, mycobiome, and virome, which blurs the potential mechanism of VMT, the researchers noted. Other limitations were the relatively short study period, small sample size, and cervical HPV screening within the past 5 years, not during pregnancy, they wrote.
However, the results suggest that VMT is safe, and may help improve the fecal microbiome in cesarean-delivered infants, and the long-term effects merit further studies in larger populations, they concluded.
Limitations and outlook
Dr. Clemente said in an interview that the researchers were “hopeful that the study would demonstrate a health benefit, as it does with some limitations.” The current study findings confirm some previous results showing that modification of the microbiomes of C-section infants is possible through a transfer of maternal vaginal microbes, he said.
“There is also an important aspect that was confirmed here: The lack of serious adverse events associated with the procedure, and the fact that transferring vaginal microbes did not increase the risk of adverse events compared to the control group or to vaginally-delivered infants. This is fundamental to establish that using rigorous exclusion criteria we can perform this procedure safely for infants and mothers,” he added.
“We are at very early stages yet to talk about clinical implications,” said Dr. Clemente. “This is one of the first studies to demonstrate a benefit to the transfer of microbes from mothers to infants, and as such it opens the way for future trials that confirm these findings. The clinical application is still in the future, but this is an important first step towards that goal.”
Interest in restoring gut microbiota to potentially benefit infants persists, but a recent study published in Frontiers and Cellular and Infection Microbiology contradicted the potential association between maternal vaginal microbiome and an infant’s gut microbiome based on an analysis of infant stool.
“There are many reasons why different studies might reach different conclusions: The experimental procedures, the analytical methods, the cohort under study,” Dr. Clemente said when asked to comment on the Frontiers study. “Further studies are needed to establish whether this procedure is equally effective under all conditions and whether health benefits are generalizable or specific to particular populations.”
Several research gaps remain, Dr. Clemente said. “First, neurodevelopment was measured through a questionnaire that captures various aspects such as communication, motor skills, or problem solving. While this is a standard way to establish that an infant is in the correct neurodevelopmental pathway, it is not a ‘hard’ measure of cellular or biochemical processes being impacted by the intervention. Some of our results suggest that there is a change in the metabolome of this infants, particularly an enrichment in GABA, a neurotransmitter, but the exact mechanisms by which the intervention is resulting in a health benefit still remains to be explored,” he said.
“We have an ongoing study here at Mount Sinai to test whether this microbial intervention can be effective in lowering the risk of developing food allergies in newborns who are at high risk, so that is another important future question: What other conditions could benefit from this approach,” said Dr. Clemente.
A third research goal, he added, is “determining what microbes precisely are responsible for the health benefits; this study uses a full microbial community to colonize infants. We show that this is effective and, importantly, that there were no significant adverse events in the treated infants,” he noted. “However, identifying what specific microbes are beneficial would further lower the risk of any potential side effects, while facilitating the development of drugs based on defined microbial consortia,” he said.
Safety and efficacy support further studies
“It is widely accepted that the gut microbiome of neonates varies based on mode of delivery,” Anna K. Knight, PhD, assistant professor of gynecology and obstetrics at Emory University, Atlanta, said in an interview.
“C-sections have been associated with increased risk of asthma and metabolic disease, and have been associated with differences in the development of the immune system,” said Dr. Knight, who was not involved in the study. “There have been small pilot studies examining the use of vaginal microbiome transplants to shift the gut microbiome of neonates born by C-section to be more like the gut microbiome of neonates born via vaginal delivery, but the safety and efficacy of this treatment has not been well established. This study examines both, while also evaluating potential changes in the metabolome and neurodevelopmental trajectories.”
The current study confirmed the impact of the neonatal gut microbe on neurodevelopmental outcomes during a sensitive period, said Dr. Knight. “The fact that these differences persisted at 6 months suggests that even if the microbiome composition between vaginally-delivered and preterm infants converged at 1-2 years old, there may be lasting impacts of mode of delivery,” she said.
“The results of this study suggest that vaginal microbiome transplant may be a safe and effective way to mitigate the negative impacts of C-section delivery on the neonatal gut microbiome, and may be protective for neurodevelopment,” she added.
Regarding the Frontiers in Medicine study, Dr. Knight noted that it examined a very different population, with Zhou and colleagues focusing on Chinese infants, while Dos Santos and colleagues focused on Canadian infants.
“There was also a substantial difference in sample size between the two studies, with Dos Santos and colleagues examining > 500 more infants,” she said. “Additionally, the two studies differed in the sequencing technology used, sample collection methods, and antibiotic exposure, which can all impact microbiome study results.”
Since the current study showed efficacy and safety of VMT in a small clinical trial, larger trials with more diverse participants are needed to further examine the impact of VMT, said Dr. Knight. “The risks of vaginal microbiome transplant in mothers with infections should also be considered, and the mechanisms by which the neonatal gut microbiome impacts neurodevelopment need further investigation,” she said.
The study was funded by the National Key R&D Program of China, the Canadian Institute of Health Research, the National Natural Science Foundation of China, the Clinical Research Startup Program of Southern Medical University, China, and the Top Talent Program of Foshan Women and Children Hospital, China. The researchers and Dr. Knight had no financial conflicts to disclose.
