COVID-19 vaccines in pregnancy may protect baby, too
Women who receive COVID-19 vaccines during pregnancy pass antibodies to their babies, which could protect newborns from the disease, research has shown.
.
Researchers with New York University Langone Health conducted a study that included pregnant women who had received at least one dose of an mRNA COVID-19 vaccine (Pfizer/BioNTech or Moderna) by June 4.
All neonates had antibodies to the spike protein at high titers, the researchers found.
Unlike similar prior studies, the researchers also looked for antibodies to the nucleocapsid protein, which would have indicated the presence of antibodies from natural COVID-19 infection. They did not detect antibodies to the nucleocapsid protein, and the lack of these antibodies suggests that the antibodies to the spike protein resulted from vaccination and not from prior infection, the researchers said.
The participants had a median time from completion of the vaccine series to delivery of 13 weeks. The study was published online in the American Journal of Obstetrics & Gynecology MFM.
“The presence of these anti-spike antibodies in the cord blood should, at least in theory, offer these newborns some degree of protection,” said study investigator Ashley S. Roman, MD, director of the division of maternal-fetal medicine at NYU Langone Health. “While the primary rationale for vaccination during pregnancy is to keep moms healthy and keep moms out of the hospital, the outstanding question to us was whether there is any fetal or neonatal benefit conferred by receiving the vaccine during pregnancy.”
Questions remain about the degree and durability of protection for newborns from these antibodies. An ongoing study, MOMI-VAX, aims to systematically measure antibody levels in mothers who receive COVID-19 vaccines during pregnancy and in their babies over time.
The present study contributes welcome preliminary evidence suggesting a benefit to infants, said Emily Adhikari, MD, of the University of Texas Southwestern Medical Center in Dallas, who was not involved in the study.
Still, “the main concern and our priority as obstetricians is to vaccinate pregnant women to protect them from severe or critical illness,” she said.
Although most individuals infected with SARS-CoV-2 recover, a significant portion of pregnant women get seriously sick, Dr. Adhikari said. “With this recent Delta surge, we are seeing more pregnant patients who are sicker,” said Dr. Adhikari, who has published research from one hospital describing this trend.
When weighing whether patients should receive COVID-19 vaccines in pregnancy, the risks from infection have outweighed any risk from vaccination to such an extent that there is “not a comparison to make,” Dr. Adhikari said. “The risks of the infection are so much higher.
“For me, it is a matter of making sure that my patient understands that we have really good safety data on these vaccines and there is no reason to think that a pregnant person would be harmed by them. On the contrary, the benefit is to protect and maybe even save your life,” Dr. Adhikari said. “And now we have more evidence that the fetus may also benefit.”
The rationale for vaccinations during pregnancy can vary, Dr. Roman said. Flu shots in pregnancy mainly are intended to protect the mother, though they confer protection for newborns as well. With the whooping cough vaccine given in the third trimester, however, the primary aim is to protect the baby from whooping cough in the first months of life, Dr. Roman said.
“I think it is really important for pregnant women to understand that antibodies crossing the placenta is a good thing,” she added.
As patients who already have received COVID-19 vaccines become pregnant and may become eligible for a booster dose, Dr. Adhikari will offer it, she said, though she has confidence in the protection provided by the initial immune response.

Study gives bleeding risk estimates for VTE patients on anticoagulants
The meta-analysis of data from 27 studies with 17,202 patients was published in the Annals of Internal Medicine. According to two of the paper’s coauthors, Faizan Khan, MSc, and Marc A. Rodger, MD, it “provides best available estimates of long-term bleeding risk with different anticoagulants in patients with unprovoked VTE,” including subgroups at increased risk.
Patients at increased risk for major bleeding include those who are older; those using antiplatelet therapy; and patients with kidney disease, a history of bleeding, or anemia, noted the coauthors, who work for the Ottawa Hospital Research Institute.
The researchers focused on randomized controlled trials (RCTs) and prospective cohort studies that reported major bleeding among patients with a first unprovoked or weakly provoked VTE who received oral anticoagulation for at least 6 months beyond an initial anticoagulant treatment course of at least 3 months.
The investigators analyzed data from 14 RCTs and 13 cohort studies. In all, 9,982 patients received a vitamin K antagonist (VKA), and 7,220 received a direct oral anticoagulant (DOAC).
The incidence of major bleeding per 100 person-years was 1.7 events with VKAs, compared with 1.1 events with DOACs. The researchers estimated that the 5-year cumulative incidence of major bleeding with VKAs was 6.3%. The available data for DOACs were insufficient to estimate the incidence of major bleeding beyond 1 year.
“This information can help clinicians counsel patients and inform shared decision-making about extended therapy,” the researchers said.
Risks of serious bleeding ‘not trivial’
Margaret Fang, MD, with the University of California, San Francisco, agreed that the study can help clinicians and patients weigh the risks of extended anticoagulation for common types of VTE.
The study also “highlights that the risks of serious bleeding are not trivial” and points out gaps in the literature regarding the long-term use of DOACs for extended VTE therapy, Dr. Fang said.
Better ways to predict which patients will develop bleeding on anticoagulants are needed, Dr. Fang added. “It will also be important to establish which of the various therapies for preventing recurrent VTE – full dose versus lowered dose, or even aspirin – has the best balance of safety and efficacy,” she said.
‘Standardized approach’ for identifying high-risk patients lacking
Clinical practice guidelines recommend indefinite anticoagulation for an unprovoked VTE, except when patients are at high risk of bleeding, the authors noted. But clinicians lack a “standardized approach to identify patients at high risk of bleeding,” Mr. Khan and Dr. Rodger said. “Evidence from randomized trials on net long-term benefit of extended therapy is limited, and current guideline recommendations are largely based on expert consensus opinion. Major bleeding events are two to three times more likely to be fatal than recurrent VTE events, so extended therapy is not always associated with a net mortality benefit, particularly in patients at low risk of recurrent VTE or high risk of bleeding.”
The analysis indicates that there is “a clinically meaningful difference in long-term risk for anticoagulant-related major bleeding among patients with a first unprovoked VTE stratified according to presence or absence of the following risk factors: age older than 65 years, creatinine clearance less than 50 mL/min, history of bleeding, concomitant use of antiplatelet therapy, and hemoglobin level less than 100 g/L,” the authors said.
For example, the researchers found that the incidence of major bleeding was higher among those older than 65 years, compared with younger patients (incidence rate ratio, 1.84 with VKAs and 2.92 with DOACs), and among those with creatinine clearance less than 50 mL/min (IRR, 2.83 with VKAs and 3.71 with DOACs).
The case-fatality rate of major bleeding was 8.3% with VKAs and 9.7% with DOACs.
The study received funding from the Canadian Institutes of Health Research. Some of the coauthors are employees of or have financial ties to pharmaceutical companies. Mr. Khan, Dr. Rodger, and Dr. Fang had no relevant disclosures.

One center’s experience delivering monochorionic twins
Between 2005 and 2021, mode of delivery of diamniotic twins at this practice did not significantly differ by chorionicity, researchers affiliated with Maternal Fetal Medicine Associates and the department of obstetrics, gynecology, and reproductive science at Icahn School of Medicine at Mount Sinai, New York reported in Obstetrics & Gynecology.
The study supports a recommendation from the American College of Obstetricians and Gynecologists that vaginal delivery “is a reasonable option in well selected diamniotic twin pregnancies, irrespective of chorionicity, and should be considered, provided that an experienced obstetrician is available,” said Iris Krishna, MD, assistant professor of maternal-fetal medicine at Emory University, Atlanta.
The experience at this practice, however, may not apply to many practices in the United States, said Dr. Krishna, who was not involved in the study.
Of 1,121 diamniotic twin pregnancies included in the analysis, 202 (18%) were monochorionic. The cesarean delivery rate was not significantly different between groups: 61% for monochorionic and 63% for dichorionic pregnancies.
Among women with planned vaginal delivery (101 monochorionic pregnancies and 422 dichorionic pregnancies), the cesarean delivery rate likewise did not significantly differ by chorionicity. Twenty-two percent of the monochorionic pregnancies and 21% of the dichorionic pregnancies in this subgroup had a cesarean delivery.
Among patients with a vaginal delivery of twin A, chorionicity was not associated with mode of delivery for twin B. Combined vaginal-cesarean deliveries occurred less than 1% of the time, and breech extraction of twin B occurred approximately 75% of the time, regardless of chorionicity.
The researchers also compared neonatal outcomes for monochorionic-diamniotic twin pregnancies at or after 34 weeks of gestation, based on the intended mode of delivery (95 women with planned vaginal delivery and 68 with planned cesarean delivery). Neonatal outcomes generally were similar, although the incidence of mechanical ventilation was less common in cases with planned vaginal delivery (7% vs. 21%).
“Our data affirm that an attempt at a vaginal birth for twin pregnancies, without contraindications to vaginal delivery and regardless of chorionicity, is reasonable and achievable,” wrote study author Henry N. Lesser, MD, with the department of obstetrics and gynecology at Sinai Hospital in Baltimore, and colleagues.
The patients with planned cesarean delivery had a contraindication to vaginal delivery or otherwise chose to have a cesarean delivery. The researchers excluded from their analysis pregnancies with intrauterine fetal demise of either twin before labor or planned cesarean delivery.
The study’s reliance on data from a single practice decreases its external validity, the researchers noted. Induction of labor at this center typically occurs at 37 weeks’ gestation for monochorionic twins and at 38 weeks for dichorionic twins, and “senior personnel experienced in intrauterine twin manipulation are always present at delivery,” the study authors said.
The study describes “the experience of a single site with skilled obstetricians following a standardized approach to management of diamniotic twin deliveries,” Dr. Krishna said. “Findings may not be generalizable to many U.S. practices as obstetrics and gynecology residents often lack training in breech extraction or internal podalic version of the second twin. This underscores the importance of a concerted effort by skilled senior physicians to train junior physicians in vaginal delivery of the second twin to improve overall outcomes amongst women with diamniotic twin gestations.”
Michael F. Greene, MD, professor emeritus of obstetrics, gynecology, and reproductive biology at Massachusetts General Hospital, Boston, agreed that the findings are not generalizable to the national population. Approximately 10% of the patients in the study had prepregnancy obesity, whereas doctors practicing in other areas likely encounter higher rates, Dr. Greene said in an interview.
He also wondered about other data points that could be of interest but were not reported, such as the racial or ethnic distribution of the patients, rates of birth defects, the use of instruments to aid delivery, and neonatal outcomes for the dichorionic twins.
Monochorionic pregnancies entail a risk of twin-twin transfusion syndrome and other complications, including an increased likelihood of birth defects.
Dr. Greene is an associate editor with the New England Journal of Medicine, which in 2013 published results from the Twin Birth Study, an international trial where women with dichorionic or monochorionic twins were randomly assigned to planned vaginal delivery or planned cesarean delivery. Outcomes did not significantly differ between groups. In the trial, the rate of cesarean delivery in the group with planned vaginal delivery was 43.8%, and Dr. Greene discussed the implications of the study in an accompanying editorial.
Since then, the obstetrics and gynecology community “has been focusing in recent years on trying to avoid the first cesarean section” when it is safe to do so, Dr. Greene said. “That has become almost a bumper sticker in modern obstetrics.”
And patients should know that it is an option, Dr. Krishna added.
“Women with monochorionic-diamniotic twins should be counseled that with an experienced obstetrician that an attempt at vaginal delivery is not associated with adverse neonatal outcomes when compared with planned cesarean delivery,” Dr. Krishna said.

Neonatal outcomes generally were similar, although the incidence of mechanical ventilation was less common in cases with planned vaginal delivery (7% vs. 21%).
“Our data affirm that an attempt at a vaginal birth for twin pregnancies, without contraindications to vaginal delivery and regardless of chorionicity, is reasonable and achievable,” wrote study author Henry N. Lesser, MD, with the department of obstetrics and gynecology at Sinai Hospital in Baltimore, and colleagues.
The patients with planned cesarean delivery had a contraindication to vaginal delivery or otherwise chose to have a cesarean delivery. The researchers excluded from their analysis pregnancies with intrauterine fetal demise of either twin before labor or planned cesarean delivery.
The study’s reliance on data from a single practice decreases its external validity, the researchers noted. Induction of labor at this center typically occurs at 37 weeks’ gestation for monochorionic twins and at 38 weeks for dichorionic twins, and “senior personnel experienced in intrauterine twin manipulation are always present at delivery,” the study authors said.
The study describes “the experience of a single site with skilled obstetricians following a standardized approach to management of diamniotic twin deliveries,” Dr. Krishna said. “Findings may not be generalizable to many U.S. practices as obstetrics and gynecology residents often lack training in breech extraction or internal podalic version of the second twin. This underscores the importance of a concerted effort by skilled senior physicians to train junior physicians in vaginal delivery of the second twin to improve overall outcomes amongst women with diamniotic twin gestations.”
Michael F. Greene, MD, professor emeritus of obstetrics, gynecology, and reproductive biology at Massachusetts General Hospital, Boston, agreed that the findings are not generalizable to the national population. Approximately 10% of the patients in the study had prepregnancy obesity, whereas doctors practicing in other areas likely encounter higher rates, Dr. Greene said in an interview.
He also wondered about other data points that could be of interest but were not reported, such as the racial or ethnic distribution of the patients, rates of birth defects, the use of instruments to aid delivery, and neonatal outcomes for the dichorionic twins.
Monochorionic pregnancies entail a risk of twin-twin transfusion syndrome and other complications, including an increased likelihood of birth defects.
Dr. Greene is an associate editor with the New England Journal of Medicine, which in 2013 published results from the Twin Birth Study, an international trial where women with dichorionic or monochorionic twins were randomly assigned to planned vaginal delivery or planned cesarean delivery. Outcomes did not significantly differ between groups. In the trial, the rate of cesarean delivery in the group with planned vaginal delivery was 43.8%, and Dr. Greene discussed the implications of the study in an accompanying editorial.
Since then, the obstetrics and gynecology community “has been focusing in recent years on trying to avoid the first cesarean section” when it is safe to do so, Dr. Greene said. “That has become almost a bumper sticker in modern obstetrics.”
And patients should know that it is an option, Dr. Krishna added.
“Women with monochorionic-diamniotic twins should be counseled that with an experienced obstetrician that an attempt at vaginal delivery is not associated with adverse neonatal outcomes when compared with planned cesarean delivery,” Dr. Krishna said.

Summer campers spread COVID at home, follow-up finds
In a report published online in The New England Journal of Medicine, researchers found that campers spread COVID to household members after returning home – but transmission was more likely from some than others. Distancing and masking helped reduce the risk.
Victoria T. Chu, MD, MPH, with the Centers for Disease Control and Prevention, Atlanta, and colleagues with the agency and the Georgia Department of Health followed up with 224 camp attendees, aged 7 to 19 years, who had evidence of SARS-CoV-2 infection on laboratory testing.
These index patients – 88% of whom had symptoms – had 526 household contacts, mainly parents and siblings. Of 377 household contacts who underwent testing, 46 (12%) tested positive. Another two cases in household contacts were identified using clinical and epidemiologic criteria.
Family members hospitalized
Of the 41 adult household contacts who were infected, four (about 10%) were hospitalized. Their hospital stays ranged from 5 to 11 days. Of the seven infected household contacts who were younger than 18 years, none were hospitalized.
The four hospitalized adults were parents and grandparents aged 45 to 80 years, Dr. Chu said. Two of the four had underlying conditions. None of the household contacts died.
In an adjusted analysis, campers who had practiced physical distancing were less likely to transmit the virus at home, compared with those who had not practiced physical distancing (adjusted odds ratio, 0.4). Household members who had had close or direct contact with the index patients were more than 5 times more likely to become infected, compared with family members with minimal or no contact, analyses showed.
“This retrospective study showed that the efficient transmission of SARS-CoV-2 from school-age children and adolescents to household members led to the hospitalization of adults with secondary cases of COVID-19,” the researchers write. “In households in which transmission occurred, half the household contacts were infected.”
The secondary attack rates in this report may be an underestimate because testing was voluntary and participants reported the results themselves, the authors note. It is possible that infected household contacts spread the virus further, but this study did not address that question, Dr. Chu said.
For the study, investigators interviewed all camp attendees and their parents or guardians by phone between July 17, 2020 and Aug. 24, 2020, to collect information about demographic and clinical characteristics, SARS-CoV-2 testing, and preventive measures. The researchers’ analysis excluded households in which illness onset in a household contact occurred before or less than 2 days after a camper became sick.
About a third of the index patients began to have symptoms while still at camp. These campers may have been less infectious by the time they got home, compared with those whose symptoms started after they returned.
Two-thirds of the index patients adopted physical distancing at home, which “probably reduced the transmission of SARS-CoV-2 in the household,” Dr. Chu and colleagues wrote.
“Children who have had a known COVID-19 exposure should quarantine and obtain testing if they develop symptoms within the 14 days of returning home,” Dr. Chu advised. “If a child develops COVID-19, the child should be cared for and monitored using the proper combination of physical distancing, isolation when feasible, and mask use to prevent household transmission as much as possible. In addition, any person over the age of 12 is now eligible for vaccination in the United States. If eligible, children attending camp and their family members should get vaccinated to protect themselves and others, as vaccinations are our most effective public health prevention strategy.”
Mitigation can help
Another report regarding four overnight camps in Maine – in which three campers tested positive after they arrived last summer – shows that “aggressive mitigation strategies can be effective” in limiting transmission of the virus, William T. Basco Jr., MD, writes in a commentary for this news organization.
This summer, a range of factors, including vaccination rates at the camp, may influence transmission dynamics, Dr. Chu said in an interview. In July, the Associated Press reported outbreaks tied to summer camps in several states.
“Transmission dynamics will probably vary from summer camp to summer camp depending on many factors, such as vaccination rates of camp attendees, the mitigation measures in place, and the number of individual introductions during camp,” Dr. Chu said. “We would expect that a camp with a low vaccination rate among attendees and no enforcement of mitigation measures” still may experience a large outbreak.
“On the other hand, a large proportion of vaccinated individuals and appropriate implementation of multiple mitigation measures, such as wearing masks, may be quite effective at keeping their transmission rates low,” Dr. Chu added. “For camps with younger children who are not currently eligible for vaccination, implementing layered prevention strategies (e.g., mask use, physical distancing, and encouraging outdoor activities when feasible) is important to prevent transmission.”
Although COVID-19 transmission from children to adults, potentially leading to hospitalization, is not a new phenomenon, “data on the extent of transmission driven by children and adolescents in different settings are still quite sparse,” Dr. Chu said. “A better understanding of their impact on household and community transmission to help guide public health recommendations is particularly important, as most children are still not eligible for vaccination, and in-person schools will be reopening this fall.”

Drinking coffee not linked to increased arrhythmia risk in new study
In fact, an adjusted analysis found that “each additional cup of coffee intake was associated with a 3% lower risk of incident arrhythmia,” Eun-jeong Kim, MD, of the division of cardiology at the University of California, San Francisco, and colleagues reported in JAMA Internal Medicine.
In addition, genetic differences that affect caffeine metabolism did not significantly influence the odds of arrhythmias, the researchers found.
Still, these findings should not necessarily encourage people to start drinking coffee if they don’t already, or to guzzle additional cups with abandon, they said.
“We certainly don’t want to say drink coffee and it will reduce your risk of arrhythmias,” study author Gregory M. Marcus, MD, MAS, associate chief of cardiology for research at UCSF Health, said in an interview. “But rather, we think the main point is that a blanket prohibition against coffee or caffeine to reduce the risk of arrhythmias among patients who have a diagnosis of arrhythmias is likely unwarranted. And given some evidence that coffee consumption may actually have other benefits regarding diabetes, mood, and perhaps overall mortality, it may be problematic to admonish patients to avoid coffee or caffeine when it is not really warranted.”
Methods and results
The conventional wisdom that caffeine increases arrhythmic risk has not been well substantiated. To further examine whether moderate, habitual coffee drinking relates to arrhythmia risk, and whether certain genetic variants influence the association, Dr. Kim and colleagues analyzed data from the UK Biobank. They focused on longitudinal data collected between 2006 and 2018 from 386,258 people who did not have a prior diagnosis of arrhythmia.
Participants had an average age of 56 years, and about 52% were female. They provided information about their coffee consumption, and the researchers grouped the participants into eight categories based on their daily coffee intake: 0, less than 1, 1, 2, 3, 4, 5, and 6 or more cups per day.
Over an average follow-up of 4.5 years, 16,979 participants developed an incident arrhythmia. After adjusting for demographic characteristics, comorbid conditions, and lifestyle habits, the decreased risk with each cup of coffee was similar for atrial fibrillation or flutter (hazard ratio, 0.97) and supraventricular tachycardia (HR, 0.96).
Taking into account genetic variations that relate to caffeine metabolism did not modify the findings. Mendelian randomization analyses that used a polygenic score of inherited caffeine metabolism patterns “failed to provide evidence that caffeine consumption leads to a greater risk of arrhythmias,” the researchers said.
Professional society guidelines have suggested staying away from caffeinated products to reduce the risk of arrhythmia, but this guidance has “relied on assumed mechanisms and a small observational study from 1980,” the authors wrote. Subsequent research has indicated that coffee’s reputation of increasing the risk of arrhythmia may be undeserved.
“The investigators should be commended on performing a high-quality observational study to try to further understand the association between coffee consumption and arrhythmias, or the lack of one,” commented Zachary D. Goldberger, MD, MS, with the division of cardiovascular medicine at the University of Wisconsin–Madison, who was not involved in the study. “This is not a randomized, controlled trial, and coffee consumption was self-reported, but the methods employed are rigorous, despite these and other important limitations. However, we need to be extremely cautious in how we interpret these findings, and not use these data as a prescription for more coffee. It’s important to recognize that this study is not telling us to drink more coffee, or start drinking coffee, to protect against developing arrhythmias. However, it should offer more reassurance that moderate coffee consumption is not necessarily harmful, and will not always lead to arrhythmias. This is important, given the widespread notion that coffee is universally proarrhythmic.”
A call for personalized guidance
“As the investigators note, there are definitely biologically plausible reasons how coffee and caffeine may not cause arrhythmias, and may be possibly protective in some, despite being a stimulant,” Dr. Goldberger said. “However, if your patient is reporting palpitations or symptoms of an arrhythmia, and feels they be related to coffee or caffeine, we should not use this study to tell them that coffee may not be the culprit. We need to listen to our patients, and the decision to reduce coffee consumption to reduce these symptoms needs to be personalized.”
The effect size was small, and only about 4% of the participants developed an arrhythmia, Dr. Goldberger and Rodney A. Hayward, MD, wrote in an invited commentary on the study in JAMA Internal Medicine. Dr. Hayward is a professor of public health and internal medicine at the University of Michigan, Ann Arbor, and a senior investigator at the Ann Arbor Veterans Affairs Center for Clinical Management Research.
“Unfortunately, coffee consumption was self-reported at a single time point. Not only can this lead to recall bias, but subsequent and substantial changes in coffee consumption are also possible, including reductions due to new signs or symptoms,” they said.
No evidence that coffee ups risk for developing arrhythmias
Another recent study suggests that people may alter their coffee consumption depending on their baseline cardiovascular health, according to the commentary.
Overall, the results “strengthen the evidence that caffeine is not proarrhythmic, but they should not be taken as proving that coffee is an antiarrhythmic—this distinction is of paramount importance,” Dr. Goldberger and Dr. Hayward wrote. “Health care professionals can reassure patients that there is no evidence that drinking coffee increases the risk for developing arrhythmias. This is particularly important for the many patients with benign palpitations who are devastated when they think, or are told, that they have to stop drinking coffee. Given current evidence, this is entirely a patient-preference decision, not a medical one.”
Dr. Marcus, a cardiac electrophysiologist, sees patients with arrhythmias all the time. They tend to “come in fairly convinced that caffeine is to be avoided when they have arrhythmias,” he said. “Often, they been told by their primary care physician or their general cardiologist to avoid caffeine because they have an arrhythmia.
“What I suggest to my patients is that they feel free to go ahead and experiment and try coffee,” Dr. Marcus said.
Still, Dr. Marcus suspects that there are some individuals in whom caffeine is a trigger for the arrhythmia. But evidence indicates these cases likely are rare, and avoiding caffeine need not apply to the general population, particularly “given the potential health benefits of benefits of coffee and also, frankly, just the enhanced quality of life that people can enjoy drinking a good cup of coffee.”
The research was conducted using the UK Biobank resource, which was established by the Wellcome Trust, the Medical Research Council, the U.K. Department of Health, and the Scottish government. The UK Biobank has received funding from other agencies and foundations as well. Dr. Marcus disclosed grants from Baylis, Medtronic, and Eight Sleep outside the submitted work. In addition, he reported consulting for Johnson & Johnson and InCarda, and holding equity in InCarda. A coauthor received salary support from the National Institutes of Health during the study. Dr. Goldberger and Dr. Hayward disclosed no conflicts of interest.

Professional society guidelines have suggested staying away from caffeinated products to reduce the risk of arrhythmia, but this guidance has “relied on assumed mechanisms and a small observational study from 1980,” the authors wrote. Subsequent research has indicated that coffee’s reputation of increasing the risk of arrhythmia may be undeserved.
“The investigators should be commended on performing a high-quality observational study to try to further understand the association between coffee consumption and arrhythmias, or the lack of one,” commented Zachary D. Goldberger, MD, MS, with the division of cardiovascular medicine at the University of Wisconsin–Madison, who was not involved in the study. “This is not a randomized, controlled trial, and coffee consumption was self-reported, but the methods employed are rigorous, despite these and other important limitations. However, we need to be extremely cautious in how we interpret these findings, and not use these data as a prescription for more coffee. It’s important to recognize that this study is not telling us to drink more coffee, or start drinking coffee, to protect against developing arrhythmias. However, it should offer more reassurance that moderate coffee consumption is not necessarily harmful, and will not always lead to arrhythmias. This is important, given the widespread notion that coffee is universally proarrhythmic.”
A call for personalized guidance
“As the investigators note, there are definitely biologically plausible reasons how coffee and caffeine may not cause arrhythmias, and may be possibly protective in some, despite being a stimulant,” Dr. Goldberger said. “However, if your patient is reporting palpitations or symptoms of an arrhythmia, and feels they be related to coffee or caffeine, we should not use this study to tell them that coffee may not be the culprit. We need to listen to our patients, and the decision to reduce coffee consumption to reduce these symptoms needs to be personalized.”
The effect size was small, and only about 4% of the participants developed an arrhythmia, Dr. Goldberger and Rodney A. Hayward, MD, wrote in an invited commentary on the study in JAMA Internal Medicine. Dr. Hayward is a professor of public health and internal medicine at the University of Michigan, Ann Arbor, and a senior investigator at the Ann Arbor Veterans Affairs Center for Clinical Management Research.
“Unfortunately, coffee consumption was self-reported at a single time point. Not only can this lead to recall bias, but subsequent and substantial changes in coffee consumption are also possible, including reductions due to new signs or symptoms,” they said.
No evidence that coffee ups risk for developing arrhythmias
Another recent study suggests that people may alter their coffee consumption depending on their baseline cardiovascular health, according to the commentary.
Overall, the results “strengthen the evidence that caffeine is not proarrhythmic, but they should not be taken as proving that coffee is an antiarrhythmic—this distinction is of paramount importance,” Dr. Goldberger and Dr. Hayward wrote. “Health care professionals can reassure patients that there is no evidence that drinking coffee increases the risk for developing arrhythmias. This is particularly important for the many patients with benign palpitations who are devastated when they think, or are told, that they have to stop drinking coffee. Given current evidence, this is entirely a patient-preference decision, not a medical one.”
Dr. Marcus, a cardiac electrophysiologist, sees patients with arrhythmias all the time. They tend to “come in fairly convinced that caffeine is to be avoided when they have arrhythmias,” he said. “Often, they been told by their primary care physician or their general cardiologist to avoid caffeine because they have an arrhythmia.
“What I suggest to my patients is that they feel free to go ahead and experiment and try coffee,” Dr. Marcus said.
Still, Dr. Marcus suspects that there are some individuals in whom caffeine is a trigger for the arrhythmia. But evidence indicates these cases likely are rare, and avoiding caffeine need not apply to the general population, particularly “given the potential health benefits of benefits of coffee and also, frankly, just the enhanced quality of life that people can enjoy drinking a good cup of coffee.”
The research was conducted using the UK Biobank resource, which was established by the Wellcome Trust, the Medical Research Council, the U.K. Department of Health, and the Scottish government. The UK Biobank has received funding from other agencies and foundations as well. Dr. Marcus disclosed grants from Baylis, Medtronic, and Eight Sleep outside the submitted work. In addition, he reported consulting for Johnson & Johnson and InCarda, and holding equity in InCarda. A coauthor received salary support from the National Institutes of Health during the study. Dr. Goldberger and Dr. Hayward disclosed no conflicts of interest.

Does early delivery for FGR affect school outcomes?
Iatrogenic delivery for suspected fetal growth restriction (FGR) may be associated with an increased likelihood of poorer school outcomes among infants born severely small for gestational age, a study of children in Australia suggests.
researchers reported in JAMA.
“It raises the question: in our efforts to improve outcomes in babies that are small, are we potentially doing more harm than good?” said Robert M. Silver, MD, of the department of obstetrics and gynecology at the University of Utah, Salt Lake City, who was not involved in the study. “I think that is a very important question to ask.”
However, “we can’t make that conclusion based on this one study,” he said in an interview. It could be that, in cases where severely small infants were delivered early, there may have been testing that indicated acute risks, and these infants may have tended to be sicker overall. “It may have been that if those babies weren’t delivered, they would have suffered a stillbirth or major brain injury,” Dr. Silver said. “It is really important that we acknowledge that we shouldn’t change our clinical practice” based on this one study.”
At the same time, the study underscores questions and challenges that surround the definition, identification, and management of suspected FGR, Dr. Silver said.
The study authors described their research as exploratory. In a related editorial Dr. Silver and Nathan R. Blue, MD said the findings should be considered hypothesis generating.
For the study, Roshan John Selvaratnam, BMedSc(Hons), a researcher affiliated with Monash University, Melbourne, and colleagues analyzed data from 181,902 children with developmental outcomes and 425,717 children with educational outcomes in Australia. They included children born at 32 weeks’ or more gestation between 2003 and 2013.
Severely small infants delivered early for suspected FGR had an average gestation of 37.9 weeks, whereas those not suspected of having FGR had an average gestation of 39.4 weeks.
Among infants who were severely small for gestational age, those delivered early for suspected FGR were more likely to be in the bottom 10th percentile on at least two developmental domains when they started school, compared with those not suspected of having FGR (16.2% vs. 12.7%; adjusted odds ratio, 1.36). They also were more likely to have low test scores in subsequent years. In grade 7, for example, the adjusted odds ratio for scoring below the national minimum standard on at least two educational domains was 1.33 (13.4% vs. 10.5%).
The researchers defined severely small for gestational age as birth weight below the third percentile. Among infants with normal growth, defined as birth weight at the 10th percentile or greater, school outcomes did not significantly differ between those with early delivery for suspected FGR and those not suspected of having FGR. Approximately 8% of the infants with normal growth had poor developmental outcomes.
The study authors described the dilemma that clinicians face with suspected FGR: “Either intervene early to prevent a small risk of stillbirth but potentially cause immediate and lifelong harm to the child or accept the increasing risk of stillbirth associated with prolonging the pregnancy to avoid more common neonatal and longer-term morbidities.”
It could be that severely small infants with suspected FGR in the study were “more compromised than those not suspected of having FGR,” which might explain the outcomes, Mr. Selvaratnam and coauthors wrote.
Another more plausible explanation is that “iatrogenic prematurity was harmful,” they said.
The researchers were unable to adjust for many factors that may influence academic success, including smoking and alcohol use during pregnancy, maternal body mass index, and breastfeeding, they noted. They also lacked information about the etiology for FGR and whether children had genetic abnormalities.
The study also does not take into account neonatal, infant, and childhood complications, Dr. Silver and Dr. Blue wrote in their editorial. “Nonetheless, these data are a welcome contribution given the knowledge gaps with regard to the optimal obstetric management of FGR.”
The establishment of a diagnostic standard for FGR is needed to properly investigate ways to improve risk stratification, diagnosis, and management, Dr. Silver and Dr. Blue added.
“What we have to do is get better at predicting which babies are at very high risk for continuing the pregnancy and which babies are at low risk for continuing the pregnancy so that we can better decide which babies would benefit from slightly early delivery,” Dr. Silver said.
Improved detection and management of FGR may be on the horizon. “Our ability to image the placental function has gotten a lot better, and I think that is really going to help us,” Dr. Silver said. Studies that aim to further improve the ability to assess whether babies are getting adequate blood flow during pregnancy are ongoing, which could further help doctors evaluate risks.
The study investigators and Dr. Silver had no conflict of interest disclosures. Dr. Blue disclosed grants from Samsung Medison and personal fees from Elsevier. The study was supported by a grant from the Australian government’s National Health and Medical Research Council Program, and Mr. Selvaratnam is supported by scholarships from an Australian government research training program and the National Centre of Research Excellence in Stillbirth.

Admissions for eating disorders double in pandemic
Medical admissions for adolescents with restrictive eating disorders more than doubled at one hospital during the first 12 months of the COVID-19 pandemic, relative to the average number of admissions in prior years, a new study shows.
Doctors are seeing similar increases across the United States and in other countries.
Providers and health care systems “may need to rapidly adapt in response to increasing demands for care during the COVID-19 pandemic,” the researchers said in their study, which was published online in Pediatrics.
To assess whether admission patterns among adolescents with restrictive eating disorders changed during the pandemic, Alana K. Otto, MD, MPH, with the division of adolescent medicine at the University of Michigan, Ann Arbor, and colleagues reviewed the charts of patients admitted to C.S. Mott Children’s Hospital, also in Ann Arbor.
Their analysis included 297 admissions among 248 patients aged 10-23 years between March 1, 2017, and March 31, 2021. Patients had an average age of about 15 years. Approximately 90% were female, and most had a diagnosis of anorexia nervosa or atypical anorexia nervosa.
Indications for medical admission included physiological instability (for example, heart rate less than 50 beats per minute while awake or blood pressure less than 90/40 mm Hg), electrolyte derangements, and acute medical complications of malnutrition such as syncope. Other possible indications included uncontrolled purging, body mass index less than 75% of the median for age and sex, acute food refusal, and failure of outpatient treatment.
Eating disorder–related admissions per month were stable prior to the pandemic. Admissions then decreased in April 2020, but subsequently increased significantly throughout the study period. In all, there were 125 admissions between April 1, 2020, and March 31, 2021. During the previous 3 years, the average number of admissions per year was 56.
Patients’ insurance status was one factor that differed before and during the pandemic. Prepandemic, about 20% of admissions were for adolescents with public insurance. During the pandemic, however, the proportion with public insurance was approximately 9%, the researchers noted. Other characteristics were generally similar.
The study was retrospective and relatively small and only looked at patients with restrictive eating disorders who were severely ill and admitted for medical stabilization. It does not reflect adolescents with eating disorders in different settings, the authors noted.
Primary care pediatricians should be familiar with indications for medical admission, such as severe bradycardia, as outlined by the Society for Adolescent Health and Medicine, they said.
Consistent trends
Unfortunately, the trend seems consistent across the nation, said Michaela M. Voss, MD, director of the the Eating Disorders Center at Children’s Mercy in Kansas City, Mo. “Our outpatient setting went from availability to get in immediately to a 6-month wait list.”
As in Michigan, Dr. Voss noted a drop in admissions as lockdowns started, followed by a spike in treatment demand that has not let up.
Dr. Voss described two of the more common presentations. In one, parents might note that their child had been getting into healthy eating and exercise before the pandemic and seemed fine. “But then COVID came, the lockdown happened, and they became overly obsessed with those things,” Dr. Voss said.
In the other presentation, kids with anxiety, depression, or OCD who lost access to their usual coping strategies and outlets developed eating disorders during the pandemic. “They focused on one of the few things they could during the lockdown, which was their own body, and then their anxiety, depression, [obsessive-compulsive disorder], and other mental health comorbidities presented as an eating disorder,” Dr. Voss said.
The increasing need for treatment over the course of the pandemic may reflect the time that it has taken for the disorders to develop, as well as the time that it takes parents to recognize the problem.
Not only are doctors seeing more cases, but patients are arriving sicker than usual, Dr. Voss said.
Major medical concerns for patients in starvation mode center on the heart, brain, and bones. In addition, refeeding syndrome poses an extreme risk, Dr. Voss noted.
The Academy for Eating Disorders has created a guide to help doctors recognize and manage risks for patients with eating disorders, which may be useful for primary care providers while they are trying to get a patient into more intensive treatment, Dr. Voss suggested. The American Academy of Pediatrics recently published a clinical report on the identification and management of eating disorders in children and adolescents.
At Johns Hopkins Hospital Children’s Center in Baltimore, “we have seen a pretty remarkable increase in the number of eating disorders in the child and adolescent space since COVID,” said Jennifer Leah Goetz, MD, a psychiatrist and medical director of the child and adolescent inpatient unit. “We have seen increasing numbers of kids presenting for acute medical stabilization and refeeding and for specific treatment for the eating disorder.”
It could be that, for people with a genetic predisposition to eating disorders, a confluence of factors related to the pandemic unmasked it. For example, children may have spent more time looking at themselves on virtual meeting platforms, which could stir lingering body image and appearance-related concerns in those who are vulnerable. And some teens who were not able to participate in athletics as usual started to watch what they eat more closely, Dr. Goetz said.
A treatment bottleneck
Patients with eating disorders “can be quite ill from a psychiatric and general medical perspective,” Dr. Goetz said. “Most psychiatrists are not particularly comfortable with the medical complications, and most internists or pediatricians are not particularly comfortable with the psychiatric complications. You end up with a patient population that can only see a really highly specialized group of individuals for care. And it is a problem. It was a problem before the pandemic, and it has been really exacerbated by what we have been going through with COVID.”
Natalie Muth, MD, MPH, RDN, a pediatrician at Children’s Primary Care Medical Group La Costa in Carlsbad, Calif., has also noticed the increase in eating disorders since COVID.
In-patient colleagues “have longer wait lists and more severe cases than they have ever seen previously,” said Dr. Muth, who chairs the American Academy of Pediatrics Section on Obesity and is an adjunct assistant professor at the University of California, Los Angeles. “In primary care, we are all having to better educate and prepare ourselves for identifying and managing patients with eating disorders.”
That could mean connecting with mental health professionals, registered dietitians, and higher levels of care. But that may be a challenge. “Accessing these resources has been more difficult due to the increasing incidence of eating disorders recently,” Dr. Muth said.
Dr. Voss acknowledged that childhood obesity is another concern for pediatricians. “However, there are appropriate and healthy and safe ways to address that,” she said. A patient with overweight or obesity who loses weight may not be doing so in a healthy way.
Clinicians should wonder if a patient’s weight is decreasing too fast. And they should ask patients questions that could help identify a problem, such as: What are they doing to cause the weight loss? Why do they want to lose the weight?
Dr. Voss added that eating disorders “do not discriminate.” While there may be a perception that all patients with eating disorders are White, upper middle–class females who are thin, “that is not the case,” Dr. Voss said. They “come in all genders, all races, all weight classes, and all ages,” she said, “and we see that variety.”
In general, there may be a need to shift how weight is discussed in clinics and society more broadly, Dr. Goetz said. Weight is an incredibly personal thing, and everyone’s genetics, metabolism, and life circumstances vary. At the same time, body mass index is not necessarily the best measure of a person’s health.
Asking a child, teen, or even an adult to go on a diet is not a benign intervention, Dr. Goetz noted. In addition, dieting is unlikely to help in the long term.
Emerging from lockdown, pressure to lose “COVID pounds” is a dangerous message for people with eating disorders, Dr. Goetz said. It also could be a dangerous message for people without eating disorders. “There are so many more interesting things about each one of us than our weight,” she added.
The study authors, Dr. Voss, Dr. Goetz, and Dr. Muth had no relevant disclosures.

Emerging from lockdown, pressure to lose “COVID pounds” is a dangerous message for people with eating disorders, Dr. Goetz said. It also could be a dangerous message for people without eating disorders. “There are so many more interesting things about each one of us than our weight,” she added.
The study authors, Dr. Voss, Dr. Goetz, and Dr. Muth had no relevant disclosures.
Medical admissions for adolescents with restrictive eating disorders more than doubled at one hospital during the first 12 months of the COVID-19 pandemic, relative to the average number of admissions in prior years, a new study shows.
Doctors are seeing similar increases across the United States and in other countries.
Providers and health care systems “may need to rapidly adapt in response to increasing demands for care during the COVID-19 pandemic,” the researchers said in their study, which was published online in Pediatrics.
To assess whether admission patterns among adolescents with restrictive eating disorders changed during the pandemic, Alana K. Otto, MD, MPH, with the division of adolescent medicine at the University of Michigan, Ann Arbor, and colleagues reviewed the charts of patients admitted to C.S. Mott Children’s Hospital, also in Ann Arbor.
Their analysis included 297 admissions among 248 patients aged 10-23 years between March 1, 2017, and March 31, 2021. Patients had an average age of about 15 years. Approximately 90% were female, and most had a diagnosis of anorexia nervosa or atypical anorexia nervosa.
Indications for medical admission included physiological instability (for example, heart rate less than 50 beats per minute while awake or blood pressure less than 90/40 mm Hg), electrolyte derangements, and acute medical complications of malnutrition such as syncope. Other possible indications included uncontrolled purging, body mass index less than 75% of the median for age and sex, acute food refusal, and failure of outpatient treatment.
Eating disorder–related admissions per month were stable prior to the pandemic. Admissions then decreased in April 2020, but subsequently increased significantly throughout the study period. In all, there were 125 admissions between April 1, 2020, and March 31, 2021. During the previous 3 years, the average number of admissions per year was 56.
Patients’ insurance status was one factor that differed before and during the pandemic. Prepandemic, about 20% of admissions were for adolescents with public insurance. During the pandemic, however, the proportion with public insurance was approximately 9%, the researchers noted. Other characteristics were generally similar.
The study was retrospective and relatively small and only looked at patients with restrictive eating disorders who were severely ill and admitted for medical stabilization. It does not reflect adolescents with eating disorders in different settings, the authors noted.
Primary care pediatricians should be familiar with indications for medical admission, such as severe bradycardia, as outlined by the Society for Adolescent Health and Medicine, they said.
Consistent trends
Unfortunately, the trend seems consistent across the nation, said Michaela M. Voss, MD, director of the the Eating Disorders Center at Children’s Mercy in Kansas City, Mo. “Our outpatient setting went from availability to get in immediately to a 6-month wait list.”
As in Michigan, Dr. Voss noted a drop in admissions as lockdowns started, followed by a spike in treatment demand that has not let up.
Dr. Voss described two of the more common presentations. In one, parents might note that their child had been getting into healthy eating and exercise before the pandemic and seemed fine. “But then COVID came, the lockdown happened, and they became overly obsessed with those things,” Dr. Voss said.
In the other presentation, kids with anxiety, depression, or OCD who lost access to their usual coping strategies and outlets developed eating disorders during the pandemic. “They focused on one of the few things they could during the lockdown, which was their own body, and then their anxiety, depression, [obsessive-compulsive disorder], and other mental health comorbidities presented as an eating disorder,” Dr. Voss said.
The increasing need for treatment over the course of the pandemic may reflect the time that it has taken for the disorders to develop, as well as the time that it takes parents to recognize the problem.
Not only are doctors seeing more cases, but patients are arriving sicker than usual, Dr. Voss said.
Major medical concerns for patients in starvation mode center on the heart, brain, and bones. In addition, refeeding syndrome poses an extreme risk, Dr. Voss noted.
The Academy for Eating Disorders has created a guide to help doctors recognize and manage risks for patients with eating disorders, which may be useful for primary care providers while they are trying to get a patient into more intensive treatment, Dr. Voss suggested. The American Academy of Pediatrics recently published a clinical report on the identification and management of eating disorders in children and adolescents.
At Johns Hopkins Hospital Children’s Center in Baltimore, “we have seen a pretty remarkable increase in the number of eating disorders in the child and adolescent space since COVID,” said Jennifer Leah Goetz, MD, a psychiatrist and medical director of the child and adolescent inpatient unit. “We have seen increasing numbers of kids presenting for acute medical stabilization and refeeding and for specific treatment for the eating disorder.”
It could be that, for people with a genetic predisposition to eating disorders, a confluence of factors related to the pandemic unmasked it. For example, children may have spent more time looking at themselves on virtual meeting platforms, which could stir lingering body image and appearance-related concerns in those who are vulnerable. And some teens who were not able to participate in athletics as usual started to watch what they eat more closely, Dr. Goetz said.
A treatment bottleneck
Patients with eating disorders “can be quite ill from a psychiatric and general medical perspective,” Dr. Goetz said. “Most psychiatrists are not particularly comfortable with the medical complications, and most internists or pediatricians are not particularly comfortable with the psychiatric complications. You end up with a patient population that can only see a really highly specialized group of individuals for care. And it is a problem. It was a problem before the pandemic, and it has been really exacerbated by what we have been going through with COVID.”
Natalie Muth, MD, MPH, RDN, a pediatrician at Children’s Primary Care Medical Group La Costa in Carlsbad, Calif., has also noticed the increase in eating disorders since COVID.
In-patient colleagues “have longer wait lists and more severe cases than they have ever seen previously,” said Dr. Muth, who chairs the American Academy of Pediatrics Section on Obesity and is an adjunct assistant professor at the University of California, Los Angeles. “In primary care, we are all having to better educate and prepare ourselves for identifying and managing patients with eating disorders.”
That could mean connecting with mental health professionals, registered dietitians, and higher levels of care. But that may be a challenge. “Accessing these resources has been more difficult due to the increasing incidence of eating disorders recently,” Dr. Muth said.
Dr. Voss acknowledged that childhood obesity is another concern for pediatricians. “However, there are appropriate and healthy and safe ways to address that,” she said. A patient with overweight or obesity who loses weight may not be doing so in a healthy way.
Clinicians should wonder if a patient’s weight is decreasing too fast. And they should ask patients questions that could help identify a problem, such as: What are they doing to cause the weight loss? Why do they want to lose the weight?
Dr. Voss added that eating disorders “do not discriminate.” While there may be a perception that all patients with eating disorders are White, upper middle–class females who are thin, “that is not the case,” Dr. Voss said. They “come in all genders, all races, all weight classes, and all ages,” she said, “and we see that variety.”
In general, there may be a need to shift how weight is discussed in clinics and society more broadly, Dr. Goetz said. Weight is an incredibly personal thing, and everyone’s genetics, metabolism, and life circumstances vary. At the same time, body mass index is not necessarily the best measure of a person’s health.
Asking a child, teen, or even an adult to go on a diet is not a benign intervention, Dr. Goetz noted. In addition, dieting is unlikely to help in the long term.
Emerging from lockdown, pressure to lose “COVID pounds” is a dangerous message for people with eating disorders, Dr. Goetz said. It also could be a dangerous message for people without eating disorders. “There are so many more interesting things about each one of us than our weight,” she added.

FROM PEDIATRICS
Gender pay gap most pronounced in procedural specialties
Salary disparities persist in academic internal medicine specialties and are most obvious in procedural specialties, such as cardiology, in which there are fewer women, research suggests.
“Substantial salary inequities persist at the highest faculty levels and specifically in procedural-based specialties,” Teresa Wang, MD, and colleagues reported in a research letter published online July 12, 2021, in JAMA Internal Medicine.
To examine the demographics and salaries of academic internal medicine physician specialists, Dr. Wang, who is with the division of cardiovascular medicine at the University of Pennsylvania, Philadelphia, and coauthors analyzed survey results from faculty at 154 U.S. medical schools.
They used data from the Association of American Medical Colleges Faculty Salary Report of 2018-2019 to assess the median annual salary, faculty rank, and gender for 21,905 faculty in 13 internal medicine specialties.
Overall, women made up less than 40% of full-time faculty across ranks. Female representation was approximately equal at the instructor and assistant ranks – 47% and 46%, respectively – but decreased to 24% at the professor level.
The authors found that women made up the majority in three specialties – general internal medicine, endocrinology, and geriatrics. In contrast, women were least represented in the procedural specialties of pulmonology, critical/intensive care, gastroenterology, and cardiology.
The greatest imbalance was in cardiology, in which only 21% were women, the researchers noted.
Across faculty ranks, the median annual salary was less for women than for men. The median salary for women was within $25,000 of that for men at all ranks except chief and was at least 90% of that for men in 10 of 13 internal medicine specialties.
Cardiology, gastroenterology, and critical/intensive care were the three specialties in which women’s median salary did not reach 90% of men’s. These specialties tended to be better paid overall, “but also demonstrated the largest gender disparities in both representation and salary, particularly within the higher ranks of cardiology and gastroenterology,” the researchers said.
The reasons for gender disparities are unclear, though internal medicine procedural specialties “have long been male dominated in composition and leadership,” the authors noted. The findings indicate that workforce gender parity may be associated with salary equity.
“Despite the growing awareness of workforce disparities in medicine, our findings suggest that women internal medicine specialists remain underpaid and are not promoted to senior level academic ranks when compared with career trajectories of their male counterparts,” study author Nosheen Reza, MD, of the division of cardiovascular medicine at the University of Pennsylvania, told this news organization.
The researchers noted that they were unable to adjust at the individual level for various factors that may influence salary, such as professional service, academic productivity, clinical volume, and supplementary funding sources, and that the results might not apply to all U.S. medical schools, in which departmental structures vary.
Procedures versus evaluation and management
Still, the research “provides an interesting snapshot of current salary disparities in academic internal medicine,” comment Rita F. Redberg, MD, and colleagues in a related editorial. Dr. Redberg, the editor of JAMA Internal Medicine, is affiliated with the department of medicine at the University of California, San Francisco.
Internal medicine has 13 specialties and dozens of subspecialties, and “procedural subspecialties are more male dominated and better paid than nonprocedural subspecialties – both topics deserving of further exploration,” the editorialists wrote.
The field needs to address various issues that drive some women to “shun male-dominated procedural-based fields – including lack of role models, macho ‘cowboy’ culture, unpredictable schedules, longer training periods, or cultural factors,” Dr. Redberg and coauthors suggested. “Concurrently, the medical profession overall, as well as specialties, should thoughtfully and frequently reassess how to distribute pay more equitably and to remove the premium currently paid for procedures over evaluation and management services.”
“Unfortunately, it is not a surprise that there continues to be a gender gap for salary in academic medicine,” Dr. Redberg said in an interview. “It was interesting to see that gender pay disparities were greatest in the procedure-intensive specialties, and we do know that procedures are much more highly reimbursed than evaluation and management time, even in the IM specialties. From a patient perspective, I think what they value most highly is having their doctor talk with them and explain treatment options and risks and benefits. Sadly, our fee-for-service–based reimbursement system values procedures more highly than talking with patients. And part of the gender gap in salary is attributed to less women being proceduralists.”
The Medicare Payment Advisory Commission “has made some excellent recommendations to Congress on helping to correct this imbalance,” Dr. Redberg added.
In a separate viewpoint article, Leah M. Marcotte, MD, of the department of medicine at the University of Washington, Seattle, and colleagues describe reasons why women physicians may have “slower promotional time lines,” compared with men, such as receiving fewer and smaller grants, being underrepresented as speakers at national conferences, and receiving fewer invitations to author editorials.
“To narrow this gap, institutions should proactively nominate women, with a greater focus on those underrepresented in medicine, for internal and external awards and speaking opportunities,” Dr. Marcotte and coauthors wrote. “Institutions should adopt policies to cover child care, breastfeeding/pumping accommodations, and dependent travel. Academic departments should continue to offer virtual speaking opportunities even after COVID-19 pandemic travel restrictions become unnecessary.”
Institutions can also assist women faculty in preparing promotion dossiers.
“Gender disparities in promotion in academic medicine have been described for decades, and yet progress to close the gap has been untenably slow,” they said. “Rather than expecting faculty to adapt to existing systems, we need to change the promotion process to work better for all.”
The authors disclosed no relevant financial relationships. Dr. Redberg has received grants from Arnold Ventures, the Greenwall Foundation, and the National Heart, Lung, and Blood Institute outside the submitted work. One viewpoint coauthor has received honoraria from the American Board of Internal Medicine, and another has received personal fees from F-Prime Capital, both outside the submitted work.

Reassuring rates of ADHD after assisted reproductive techniques
according to a study published in Pediatrics.
The findings, based on an analysis of data from more than 1.5 million children in Sweden, provide “additional reassurance concerning offspring neurodevelopment after use of ART,” study author Chen Wang, MPH, and colleagues said. The results show the importance of accounting for underlying infertility when studying ART safety, they added. Mr. Wang is a researcher in the department of medical epidemiology and biostatistics at Karolinska Institutet in Stockholm.
Prior research has not shown major differences during early childhood between children conceived with ART and those conceived spontaneously. To examine long-term neurodevelopmental outcomes, including ADHD and school performance, the investigators analyzed data in Swedish population registers from children born between 1986 and 2012.
Infertility and the use of ART became increasingly common during the study period, the researchers noted. Between 1986 and 2001, 7% of births were to couples with known infertility, and 13% of these births were achieved with ART. Between 1996 and 2012, 11% of births were to couples with infertility, and 26% of these births were achieved with ART.
“Couples with infertility were more likely older and married or cohabiting, compared with couples with no known infertility,” Mr. Wang and colleagues reported. “Among infertile couples, those that conceived with ART had, on average, higher age and education, and the women were less likely to smoke.”
The investigators estimated that the cumulative incidence of ADHD by age 15 years was 6.2% in children conceived with ART, 7.3% among children of couples with infertility who did not use ART, and 7.1% in children born to couples with no known infertility.
Overall, children conceived with ART were at lower risk of ADHD (hazard ratio, 0.83). But after adjusting for parental characteristics and health factors, the researchers found a “slightly elevated risk of ADHD with ART,” with adjusted HRs of 1.05-1.07.
When the researchers focused on children born to couples with infertility, ART was associated with a lower risk of ADHD (adjusted HR, 0.80), compared with spontaneous conception. Accounting for parental characteristics and health history, however, “attenuated the association toward the null,” the researchers reported.
The researchers also compared ART methods, including intracytoplasmic sperm injection versus standard in vitro fertilization (IVF), and fresh embryo transfer versus frozen embryo transfer. The various procedures were not associated with substantially different risks.
Patterns for school performance were generally similar to those for ADHD.
“In this large follow-up of nationwide birth cohorts, we observed lower risk of ADHD and slightly better overall school performance in children conceived with ART, compared with all other children. Differences in parental characteristics appeared to completely explain and even slightly reverse the associations,” the study authors said. “When the comparison was restricted to children of couples with known infertility, no differences were seen.”
The study was well designed and “spans more than 25 years of ART during which treatments have changed dramatically,” commented Barbara Luke, ScD, MPH, professor of obstetrics, gynecology, and reproductive biology at Michigan State University, East Lansing.
Dr. Luke and colleagues have studied academic achievement in children conceived with IVF in Texas. The results of the Swedish study “are in line with U.S. studies, and are generally reassuring,” Dr. Luke said.
The U.S. studies also showed that parental factors may play a role in understanding academic performance.
“In our studies of third-grade and sixth-grade academic outcomes, we found differences by racial/Hispanic origin groups, gender, and maternal age,” she said.
The study by Mr. Wang and coauthors was funded by grants from a Swedish government agency and the National Institutes of Health. The researchers and Dr. Luke had no relevant financial disclosures.

The investigators estimated that the cumulative incidence of ADHD by age 15 years was 6.2% in children conceived with ART, 7.3% among children of couples with infertility who did not use ART, and 7.1% in children born to couples with no known infertility.
Overall, children conceived with ART were at lower risk of ADHD (hazard ratio, 0.83). But after adjusting for parental characteristics and health factors, the researchers found a “slightly elevated risk of ADHD with ART,” with adjusted HRs of 1.05-1.07.
When the researchers focused on children born to couples with infertility, ART was associated with a lower risk of ADHD (adjusted HR, 0.80), compared with spontaneous conception. Accounting for parental characteristics and health history, however, “attenuated the association toward the null,” the researchers reported.
The researchers also compared ART methods, including intracytoplasmic sperm injection versus standard in vitro fertilization (IVF), and fresh embryo transfer versus frozen embryo transfer. The various procedures were not associated with substantially different risks.
Patterns for school performance were generally similar to those for ADHD.
“In this large follow-up of nationwide birth cohorts, we observed lower risk of ADHD and slightly better overall school performance in children conceived with ART, compared with all other children. Differences in parental characteristics appeared to completely explain and even slightly reverse the associations,” the study authors said. “When the comparison was restricted to children of couples with known infertility, no differences were seen.”
The study was well designed and “spans more than 25 years of ART during which treatments have changed dramatically,” commented Barbara Luke, ScD, MPH, professor of obstetrics, gynecology, and reproductive biology at Michigan State University, East Lansing.
Dr. Luke and colleagues have studied academic achievement in children conceived with IVF in Texas. The results of the Swedish study “are in line with U.S. studies, and are generally reassuring,” Dr. Luke said.
The U.S. studies also showed that parental factors may play a role in understanding academic performance.
“In our studies of third-grade and sixth-grade academic outcomes, we found differences by racial/Hispanic origin groups, gender, and maternal age,” she said.
The study by Mr. Wang and coauthors was funded by grants from a Swedish government agency and the National Institutes of Health. The researchers and Dr. Luke had no relevant financial disclosures.
FROM PEDIATRICS
Hearing loss tied to decline in physical functioning
published online in JAMA Network Open.
Hearing loss is associated with slower gait and, in particular, worse balance, the data suggest.
“Because hearing impairment is amenable to prevention and management, it potentially serves as a target for interventions to slow physical decline with aging,” the researchers said.
To examine how hearing impairment relates to physical function in older adults, Pablo Martinez-Amezcua, MD, PhD, MHS, a researcher in the department of epidemiology at Johns Hopkins University, Baltimore, and colleagues analyzed data from the ongoing Atherosclerosis Risk in Communities (ARIC) study.
ARIC initially enrolled more than 15,000 adults in Maryland, Minnesota, Mississippi, and North Carolina between 1987 and 1989. In the present study, the researchers focused on data from 2,956 participants who attended a study visit between 2016 and 2017, during which researchers assessed their hearing using pure tone audiometry.
Hearing-study participants had an average age of 79 years, about 58% were women, and 80% were White. Approximately 33% of the participants had normal hearing, 40% had mild hearing impairment, 23% had moderate hearing impairment, and 4% had severe hearing impairment.
Participants had also undergone assessment of physical functioning at study visits between 2011 and 2019, including a fast-paced 2-minute walk test to measure their walking endurance. Another assessment, the Short Physical Performance Battery (SPPB), tests balance, gait speed, and chair stands (seated participants stand up and sit back down five times as quickly as possible while their arms are crossed).
Dr. Martinez-Amezcua and colleagues found that severe hearing impairment was associated with a lower average SPPB score compared with normal hearing in a regression analysis. Specifically, compared with those with normal hearing, participants with severe hearing impairment were more likely to have low scores on the SPPB (odds ratio, 2.72), balance (OR, 2.72), and gait speed (OR, 2.16).
However, hearing impairment was not significantly associated with the chair stand test results. The researchers note that chair stands may rely more on strength, whereas balance and gait speed may rely more on coordination and movement.
The team also found that people with worse hearing tended to walk a shorter distance during the 2-minute walk test. Compared with participants with normal hearing, participants with moderate hearing impairment walked 2.81 meters less and those with severe hearing impairment walked 5.31 meters less on average, after adjustment for variables including age, sex, and health conditions.
Participants with hearing impairment also tended to have faster declines in physical function over time.
Various mechanisms could explain associations between hearing and physical function, the authors said. For example, an underlying condition such as cardiovascular disease might affect both hearing and physical function. Damage to the inner ear could affect vestibular and auditory systems at the same time. In addition, hearing impairment may relate to cognition, depression, or social isolation, which could influence physical activity.
“Age-related hearing loss is traditionally seen as a barrier for communication,” Dr. Martinez-Amezcua told this news organization. “In the past decade, research on the consequences of hearing loss has identified it as a risk factor for cognitive decline and dementia. Our findings contribute to our understanding of other negative outcomes associated with hearing loss.”
Randomized clinical trials are the best way to assess whether addressing hearing loss might improve physical function, Dr. Martinez-Amezcua said. “Currently there is one clinical trial (ACHIEVE) that will, among other outcomes, study the impact of hearing aids on cognitive and physical function,” he said.
Although interventions may not reverse hearing loss, hearing rehabilitation strategies, including hearing aids and cochlear implants, may help, he added. Educating caregivers and changing a person’s environment can also reduce the effects hearing loss has on daily life, Dr. Martinez-Amezcua said.
“We rely so much in our sense of vision for activities of daily living that we tend to underestimate how important hearing is, and the consequences of hearing loss go beyond having trouble communicating with someone,” he said.
This study and prior research “raise the intriguing idea that hearing may provide essential information to the neural circuits underpinning movement in our environment and that correction for hearing loss may help promote physical well-being,” Willa D. Brenowitz, PhD, MPH, and Margaret I. Wallhagen, PhD, GNP-BC, both at the University of California, San Francisco, wrote in an accompanying commentary. “While this hypothesis is appealing and warrants further investigation, there are multiple other potential explanations of such an association, including potential sources of bias that may affect observational studies such as this one.”
Beyond treating hearing loss, interventions such as physical therapy or tai chi may benefit patients, they suggested.
Because many changes occur during older age, it can be difficult to understand which factor is influencing another, Dr. Brenowitz said in an interview. There are potentially relevant mechanisms through which hearing could affect cognition and physical functioning. Still another explanation could be that some people are “aging in a faster way” than others, Dr. Brenowitz said.
