Despite effective therapies, fibroid care still lacking
In 2022, two colleagues from Johns Hopkins University, Baltimore, Bhuchitra Singh, MD, MPH, MS, MBA, and James Segars Jr., MD, reviewed the available literature to evaluate the effectiveness of newer minimally invasive therapies in reducing bleeding and improving the quality of life and control of symptoms linked to uterine fibroids.
Their goal, according to Dr. Segars, a professor of obstetrics and gynecology and director of the division of women’s health research at Johns Hopkins, was to help guide clinicians and patients in making decisions about the use of the newer therapies, including radiofrequency ablation and ultrasound-guided removal of lesions.
But he and Dr. Singh, the director of clinical research at the Howard W. and Georgeanna Seegar Jones Laboratory of Reproductive Sciences and Women’s Health Research, were surprised by their findings. “The outcomes were relatively the same,” Dr. Segars said. “All of the modalities lead to significant reduction in bleeding and other fibroid-related symptoms.”
The data on long-term complications and risk for recurrence are sparse for some of the newer approaches, and not enough high-quality long-term studies have been conducted for the Food and Drug Administration to approve them as fertility-sparing treatments.
But perhaps, the biggest challenge now is to ensure that women can take advantage of these newer therapies, with large gaps in both the diagnosis of fibroids and geographic access to minimally invasive treatments.
A widespread condition widely underdiagnosed
Uterine fibroids occur in most women (the incidence rises with age) and can be found in up to 70% of women by the time they reach menopause. Risk factors include family history, increasing interval since last birth, hypertension, and obesity. Increasing parity and use of oral contraceptives are protective.
But as many as 50% of cases go undiagnosed, and one reason for this is the failure of clinicians to dig deeply enough into women’s menstrual histories to diagnose fibroids.
“The most common cause of anemia is heavy menstrual bleeding,” said Shannon Laughlin-Tommaso, MD, MPH, a professor of obstetrics and gynecology at Mayo Clinic in Rochester, Minn. She frequently sees patients who have already undergone colonoscopy to work-up the source of their anemia before anyone suspects that fibroids are the culprit.
“When women tell us about their periods, what they’ve been told is normal [bleeding] – or what they’ve always had and considered normal – is actually kind of on the heavier spectrum,” she said.
Ideally, treatment for uterine fibroids would fix abnormally prolonged or heavy menstrual bleeding, relieve pain, and ameliorate symptoms associated with an enlarged uterus, such as pelvic pressure, urinary frequency, and constipation. And the fibroids would never recur.
By those measures, hysterectomy fits the bill: Success rates in relieving symptoms are high, and the risk for recurrence is zero. But the procedure carries significant drawbacks: short-term complications of surgery, including infection, bleeding, and injury to the bowels and bladder along with potential long-term risks for cardiovascular disease, cancer, ovarian failure and premature menopause, depression, and decline in cognitive function. Those factors loom even larger for women who still hope to have children.
For that reason, the American College of Obstetricians and Gynecologists recommends myomectomy, or surgical removal of individual fibroids, for women who desire uterine preservation or future pregnancy. And the literature here is solid, according to Dr. Singh, who found that 95% of myomectomy patients achieved control of their bleeding symptoms, whether it was via laparoscopy, hysteroscopy, or laparotomy. Up to 40% of women may develop new fibroids, or leiomyomas, within 3 years, although only 12.2% required a second surgery up to after 5 years.
But myomectomy is invasive, requiring general anesthesia, incisions in the uterus, and stitches to close the organ.
Newer techniques have emerged that can effectively treat symptoms of fibroids without requiring surgery. Uterine artery embolization (UAE), which involves passing a catheter into the femoral artery, or laparoscopic uterine artery occlusion can be used to cut off the blood supply of the fibroid. Other techniques, including focused ultrasound surgery and radiofrequency ablation (RFA), use various forms of energy to heat and ablate fibroids. The latter two can be performed in outpatient settings and often without general anesthesia.
Approved for use in 1994, UAE has the most data available, with reduction in the volume of fibroids and uterine tissue lasting up to 5 years, and rates of reintervention of 19%-38% between 2 and 5 years after the procedure. Dr. Singh’s review found that 79%-98.5% of recipients of the procedure reported declines in bleeding that persisted for several years, which is comparable to myomectomy. Quality of life and pain scores also showed good improvement, with follow-up in the different studies ranging from 12 months to over 5 years, the analysis showed.
UAE does have its drawbacks. In rare cases, embolization can deprive the entire uterus and ovaries of blood, which can cause ovarian dysfunction and potentially result in premature menopause, although this outcome is most common in women who are older than 45 years. The procedure can often also be painful enough that overnight hospitalization is required.
Focused ultrasound surgeries, which include magnetic resonance–guided focused ultrasound surgery (MRgFUS) and high-intensity focused ultrasound (HIFU), were approved by the FDA in 2004. Focused ultrasound waves pass through the abdominal wall and produce significant heating, causing a burn that destroys the targeted tissue without damaging surrounding tissue. As with UAE, improvements in fibroid-associated bleeding and measures of quality of life were similar to those after myomectomy up to 3 years later.
But Dr. Singh noted that both focused ultrasound and RFA can damage the skin or internal organs. “[As] always with the thermal interventions, there is the probability of skin as well as internal organs that might get the thermal energy if it’s not focused correctly on to the fibroid itself,” he said. In addition, MRgFUS is not an option for women who are not good candidates to undergo an MRI, such as those with claustrophobia or pacemakers.
Also, with focus ultrasound and RFA, “we do worry about that fibroid getting blood flow back,” which can lead to recurrence of heavy menstrual bleeding, Dr. Laughlin-Tommaso noted.
Although data on RFA are limited to 12 months of follow-up, most women reported meaningful reductions in bleeding symptoms. Longer follow-up has been reported for bleeding symptoms after MRgFUS, with similar results up to 3 years later.
For Leslie Hansen-Lindner, MD, chief of obstetrics and gynecology at Atrium Health in Charlotte, N.C., choosing the right procedure starts with a patient-centered conversation weighing the pros and cons of the options and the woman’s goals.
“Is their goal to reduce the size and impact of their fibroid, bleed less, and have a better quality of life on their period?” Dr. Hansen-Lindner said. “Or is their goal to have the entire fibroid removed?”
If the former, an RFA is appealing to many women. If the latter, laparoscopic or mini-laparotomy myomectomy might be a better choice. Although fewer than 10% of patients require surgical reintervention at 3 years of follow-up for RFA, myomectomy has more consistent long-term evidence showing that fewer women require re-intervention and preserve their fertility, she added.
Age also plays a role in the decision: The closer a woman is to menopause, the less likely she is to experience a recurrence, so a less-invasive procedure is preferable. But for younger women hoping to become pregnant, the lower risk for recurrence and good prognosis for future fertility might sway the choice toward myomectomy.
The first laparoscopic RFA procedures were approved for uterine fibroids in 2012. Dr. Hansen-Lindner is a proponent of transcervical fibroid ablation (TFA), a newer RFA procedure that the FDA approved in 2018. Performed through the cervix, TFA requires no incisions and can generally be done without general anesthesia. Eligible candidates would be any woman with symptomatic fibroids, such as heavy menstrual bleeding, pain, or bulk symptoms. The contraindications are few.
“It’s going to come down to size and location of fibroids, and whether or not they would be accessible by the TFA,” Dr. Hansen-Lindner said. “I have to make sure that there isn’t a fibroid blocking their cervix and that the fibroids are accessible with this device.”
TFA also is not suitable for removing most submucosal lesions, which typically must be removed by hysteroscopic myomectomy. Dr. Hansen-Lindner said that she often uses TFA in conjunction with hysteroscopic myomectomy for this scenario. Although data on pregnancy after RFA (including TFA), MRgFUS, and HIFU are lacking, Gynesonics, the manufacturer of the Sonata System (the device that delivers radiofrequency energy to shrink the fibroid) has documented 79 pregnancies among the 2,200 women who have undergone TFA in the United States since 2018.
Disparities hampering care
Uterine fibroids are a particular problem for Black women, whose symptoms are more likely to be ignored by clinicians, according to Jodie Katon, PhD, a core investigator at the Veterans Affairs Greater Los Angeles Center for the Study of Healthcare Innovation, Implementation and Policy. Dr. Katon cited studies in which Black women interviewed about their experiences reported a consistent theme: Clinicians dismissed their symptoms, told them these were nothing to worry about, and advised them to lose weight. Those interactions not only delayed diagnosis among Black women but also led many of them to mistrust clinicians and avoid the health care system altogether.
The failure of clinicians to take their complaints seriously is just one of the disparities affecting Black women. In reviewing the literature, Dr. Laughlin-Tommaso, who also serves as the associate dean for Education Diversity, Equity, and Inclusion at the Mayo Clinic, found that African American women experience two to three times the risk for fibroids, compared with White women, as well as earlier onset and more severe disease, as measured by number and size of the lesions.
According to Dr. Katon, the etiology of fibroids is still poorly understood. “What we do know is that Black women are disproportionately exposed to a variety of factors that we have shown through observational studies are associated with increased risk of development of uterine fibroids.”
The list includes factors like stress; interpersonal racism; early age at menarche; various indicators of poor diets, such as vitamin D deficiency; the use of certain beauty products, specifically hair straighteners; as well as exposure to air pollution and other environmental toxins.
Laughlin-Tommaso also pointed to historical disparities in management, citing a doubled risk for hysterectomy for Black women in a study published in 2007 despite survey data suggesting that Black women report being more interested in uterine-preserving therapies rather than a hysterectomy.
Breaking down barriers of access to new treatments
Dr. Laughlin-Tommaso looked at more recent trends in the management of fibroids using data from the multicenter COMPARE-UF study, which enrolled women between 2015 and 2020 undergoing fibroid treatment into a longitudinal registry to track their outcomes. She found that Black women underwent hysterectomies at a lower rate than did White women and were instead more likely to undergo myomectomy or UAE.
Some of the change may reflect lack of approved minimally invasive procedures before 2000. “But now that we have expanded options, I think most women are opting not to have a hysterectomy,” Dr. Laughlin-Tommaso said.
Dr. Katon has research funding from the VA to look more closely at racial disparities in the treatment of fibroids. In a study published in April 2023, she reported some surprising trends.
During the period from 2010 to 2018, she found that Black veterans diagnosed with fibroids were less likely than White veterans were to receive treatment, regardless of their age or the severity of their symptoms. This finding held even among women with anemia, which should have been a clear indication for treatment.
But, as in the COMPARE-UF study, the subset of Black veterans who received an interventional treatment were less likely than their White peers were to undergo hysterectomy in favor of a fertility-sparing treatment as their initial procedure. Dr. Katon called it a “welcome but unexpected finding.”
But another significant barrier remains: The two newest types of procedures, RFA and guided focused ultrasound, are not commonly performed outside of tertiary care facilities. However, studies have found that all these procedures are cost effective (studies for myomectomy, UAE, MRgFUS, and TFA). The implementation of a category 1 billing code for laparoscopic RFA in 2017 has led more insurance companies to cover the service, and a category 1 code will be available for TFA effective January 2024.
Although RFA does require investment in specialized equipment, which limits facilities from offering the procedure, any gynecologist who routinely performs hysteroscopy can easily learn to do TFA. And the VA, which is committed to eliminating disparities in women’s health, established a 2-year advanced fellowship in minimally invasive gynecologic surgery in 2022 to help expand their capacity to offer these procedures.
The VA has been rapidly expanding their gynecology services, and Katon said that she is confident that ultrasound-guided procedures and RFA will become more available within the system. “I would say we’re keeping pace. And in some ways, you know, as a national system we may be positioned to actually outpace the rest of the U.S.”
Dr. Segars reported prior research funding for clinical trials from BioSpecifics Technologies, Bayer, Allergan, AbbVie, and ObsEva and currently receives funding from Myovant Sciences. Dr. Hansen-Lindner reported personal fees from Gynesonics. Dr. Singh, Dr. Laughlin-Tommaso, and Dr. Katon reported no financial conflicts of interest.

“It’s going to come down to size and location of fibroids, and whether or not they would be accessible by the TFA,” Dr. Hansen-Lindner said. “I have to make sure that there isn’t a fibroid blocking their cervix and that the fibroids are accessible with this device.”
TFA also is not suitable for removing most submucosal lesions, which typically must be removed by hysteroscopic myomectomy. Dr. Hansen-Lindner said that she often uses TFA in conjunction with hysteroscopic myomectomy for this scenario. Although data on pregnancy after RFA (including TFA), MRgFUS, and HIFU are lacking, Gynesonics, the manufacturer of the Sonata System (the device that delivers radiofrequency energy to shrink the fibroid) has documented 79 pregnancies among the 2,200 women who have undergone TFA in the United States since 2018.
Disparities hampering care
Uterine fibroids are a particular problem for Black women, whose symptoms are more likely to be ignored by clinicians, according to Jodie Katon, PhD, a core investigator at the Veterans Affairs Greater Los Angeles Center for the Study of Healthcare Innovation, Implementation and Policy. Dr. Katon cited studies in which Black women interviewed about their experiences reported a consistent theme: Clinicians dismissed their symptoms, told them these were nothing to worry about, and advised them to lose weight. Those interactions not only delayed diagnosis among Black women but also led many of them to mistrust clinicians and avoid the health care system altogether.
The failure of clinicians to take their complaints seriously is just one of the disparities affecting Black women. In reviewing the literature, Dr. Laughlin-Tommaso, who also serves as the associate dean for Education Diversity, Equity, and Inclusion at the Mayo Clinic, found that African American women experience two to three times the risk for fibroids, compared with White women, as well as earlier onset and more severe disease, as measured by number and size of the lesions.
According to Dr. Katon, the etiology of fibroids is still poorly understood. “What we do know is that Black women are disproportionately exposed to a variety of factors that we have shown through observational studies are associated with increased risk of development of uterine fibroids.”
The list includes factors like stress; interpersonal racism; early age at menarche; various indicators of poor diets, such as vitamin D deficiency; the use of certain beauty products, specifically hair straighteners; as well as exposure to air pollution and other environmental toxins.
Laughlin-Tommaso also pointed to historical disparities in management, citing a doubled risk for hysterectomy for Black women in a study published in 2007 despite survey data suggesting that Black women report being more interested in uterine-preserving therapies rather than a hysterectomy.
Breaking down barriers of access to new treatments
Dr. Laughlin-Tommaso looked at more recent trends in the management of fibroids using data from the multicenter COMPARE-UF study, which enrolled women between 2015 and 2020 undergoing fibroid treatment into a longitudinal registry to track their outcomes. She found that Black women underwent hysterectomies at a lower rate than did White women and were instead more likely to undergo myomectomy or UAE.
Some of the change may reflect lack of approved minimally invasive procedures before 2000. “But now that we have expanded options, I think most women are opting not to have a hysterectomy,” Dr. Laughlin-Tommaso said.
Dr. Katon has research funding from the VA to look more closely at racial disparities in the treatment of fibroids. In a study published in April 2023, she reported some surprising trends.
During the period from 2010 to 2018, she found that Black veterans diagnosed with fibroids were less likely than White veterans were to receive treatment, regardless of their age or the severity of their symptoms. This finding held even among women with anemia, which should have been a clear indication for treatment.
But, as in the COMPARE-UF study, the subset of Black veterans who received an interventional treatment were less likely than their White peers were to undergo hysterectomy in favor of a fertility-sparing treatment as their initial procedure. Dr. Katon called it a “welcome but unexpected finding.”
But another significant barrier remains: The two newest types of procedures, RFA and guided focused ultrasound, are not commonly performed outside of tertiary care facilities. However, studies have found that all these procedures are cost effective (studies for myomectomy, UAE, MRgFUS, and TFA). The implementation of a category 1 billing code for laparoscopic RFA in 2017 has led more insurance companies to cover the service, and a category 1 code will be available for TFA effective January 2024.
Although RFA does require investment in specialized equipment, which limits facilities from offering the procedure, any gynecologist who routinely performs hysteroscopy can easily learn to do TFA. And the VA, which is committed to eliminating disparities in women’s health, established a 2-year advanced fellowship in minimally invasive gynecologic surgery in 2022 to help expand their capacity to offer these procedures.
The VA has been rapidly expanding their gynecology services, and Katon said that she is confident that ultrasound-guided procedures and RFA will become more available within the system. “I would say we’re keeping pace. And in some ways, you know, as a national system we may be positioned to actually outpace the rest of the U.S.”
Dr. Segars reported prior research funding for clinical trials from BioSpecifics Technologies, Bayer, Allergan, AbbVie, and ObsEva and currently receives funding from Myovant Sciences. Dr. Hansen-Lindner reported personal fees from Gynesonics. Dr. Singh, Dr. Laughlin-Tommaso, and Dr. Katon reported no financial conflicts of interest.

Illicit steroids: If MDs don’t ask, patients won’t tell
Before he attended medical school, Thomas O’Connor, MD, had a not-very-well-kept secret: As a competitive powerlifter, he had used steroids to build strength.
Now an internist and clinical instructor of medicine at the University of Connecticut, Farmington, Dr. O’Connor’s practice focuses on the needs of men taking testosterone and other anabolic steroids – a group he feels is poorly understood and largely neglected by conventional medical care, perceptions borne out by a 2020 study of steroid users he helped conduct.
“They felt discriminated against, they did not feel comfortable working with their physicians, and they felt that the doctors did not know what they were doing,” Dr. O’Connor said in an interview. His patients often express anger and frustration with doctors they had seen previously.
Patients turning to home tests
Clients can order a panel of labs designed to screen for health conditions commonly associated with use of AAS, such as dyslipidemia, renal and hepatic dysfunction, polycythemia, thrombosis, and insulin resistance. The panels also include tests for levels of different hormones.
Sales of direct-to-consumer tests topped $3.6 billion in the United States in 2022 and are predicted to grow. Some of that spending is coming from people, mostly men, using illegally obtained steroids to build muscle. Although published data on the size of the bodybuilder market are unavailable, the Internet is a ready source of relatively inexpensive tests aimed at helping individuals monitor their health.
While clinicians may have their doubts about allowing patients to pick and choose tests and interpret their results, proponents claim they empower consumers to take control of their health – and save themselves money in the process.
But a test panel designed to help the user monitor the effects of banned substances is a bit unnerving to many clinicians, including Dr. O’Connor.
“People using anabolic steroids should be aware of the health risks associated with such use and that laboratory analysis is an important step toward improving health outcomes,” he said, “I’m all about open education, but not self-diagnosis and treatment.”
Testosterone and other AAS such as nandrolone, trenbolone, and boldenone are Schedule III controlled substances that have been banned by numerous athletic governing bodies. Yet recreational users can easily obtain them from online international pharmacies without a prescription. Should they be monitoring themselves for side effects?
A basic problem is that few primary care clinicians routinely ask their patients about the use of AAS or feel competent to manage the complications or withdrawal symptoms associated with the agents. And they may have no idea what the average AAS user looks like.
The American College of Sports Medicine updated its statement on the use of AAS in 2021. The statement warned of a growing new segment of users – up to 70% of people who take the drugs do so recreationally in pursuit of a more muscular appearance, rather than competitive athletes seeking enhanced performance.
The ACSM highlighted the syndrome of muscle dysmorphia, also known as “megarexia” or “bigorexia” (think of it as “reverse anorexia”), as a major risk factor for illicit use of AAS.
Stuart Phillips, PhD, professor and director of the department of kinesiology at McMaster University, Hamilton, Ont., coauthored the ACSM guidelines.
“The prince in Snow White circa 1950s was a guy with nice hair,” said Dr. Phillips, pointing to a change in cultural expectations for the male body. “But then fast forward to the prince or hero in any other Disney movie recently – and the guy is jacked.”
Since the last guidelines were published in 1987, Dr. Phillips has seen some cultural shifts. Testosterone has gone from a banned substance no one talked about to a mainstream medical therapy for men with low androgen levels, as any television viewer of primetime sports can attest. “But the other thing that’s changed,” he added, “is that we’ve seen the proliferation of illicit anabolic steroid use solely for the purpose of aesthetics.”
As an adolescent medicine physician who specializes in eating disorders, Jason Nagata, MD, MSc, sees many young men in his practice who engage in different behaviors to increase their muscle mass – from exercising, consuming high protein diets or taking protein supplements, even injecting AAS.
“A third of teenage boys across the U.S. report they’re trying to gain weight to bulk up and gain muscle,” said Dr. Nagata, an associate professor of pediatrics at the University of California, San Francisco.
In a 2020 study published in JAMA Pediatrics, Dr. Nagata and colleagues found that use of legal performance-enhancing substances in young men aged 18-26 years was associated with a higher odds of using AAS 7 years later (adjusted odds ratio, 3.18; 95% confidence interval, 1.90-5.32). “Some of the legal performance-enhancing substances like the protein powders or creatine may serve as a gateway to use of AAS,” Dr. Nagata said.
Another important factor is exposure to AAS use on social media, where muscular influencers gain huge followings. Dr. Nagata said most of the research on eating disorders and social media has examined the role of media on weight loss in girls.
“Although there’s less research on the social media impact on boys and men, a few studies have shown links between more Instagram use and muscle dissatisfaction, as well as thinking about using steroids,” he said.
The number of people using AAS is not trivial. In a longitudinal study (led by Nagata) of young U.S. adults surveyed multiple times between 1994 and 2002, a total of 2.7% of 18- to 26-year-old men and 0.4% of women reported using AAS. In a more recent cohort of adolescents in Minnesota aged 14-22 years followed between 2010 and 2018, a total of 2.2% of males and 1% of females initiated AAS use.
The Endocrine Society has estimated that between 2.9 and 4 million Americans have used an AAS at some point in their lives. Given that use is illegal without a prescription, a limitation of any survey is that participants may not be willing to disclose their AAS habit, leading to an underestimate of the actual number.
Nor are the complications of AAS use negligible. The drugs can have wide-ranging effects on the body, potentially affecting the brain, heart, liver, kidneys, musculoskeletal system, immune system, and reproductive systems. And individuals might unknowingly expose themselves to AAS: A recent literature review found that over a quarter of dietary supplements tested were found to contain undeclared substances that are on the World Anti-Doping Agency’s list of banned agents.
Alarming mistrust of MDs
Dr. O’Connor’s study shed some light on why AAS users might resort to surfing the Internet looking for a way to diagnose their own complications from steroid use. The web-based survey of nearly 2,400 men who said they took the drugs found that participants considered physicians to be the worst source of information, ranking them below coaches, online bodybuilding forums and sites, other AAS users, and bodybuilding books or magazines. The majority (56%) did not reveal AAS use to their clinicians. Of those who did, 55% reported feeling discriminated against for the admission.
Dr. O’Connor said physicians receive scant education on the many different drugs and regimens used by bodybuilders and have no idea how to a manage withdrawal syndrome for people trying to get off steroids. He urged the medical community to develop an educational campaign for clinicians, similar to those from public health officials aimed at combating the opioid epidemic: “Let’s educate med students and the residents. Let’s put [steroid use] on our agenda.”
Consumer testing evangelist ... or physician nemesis?
Nelson Vergel, BSChE, MBA, is on a mission to make medical lab testing affordable and accessible to everyone. The chemical engineer founded Discounted Labs 8 years ago, offering commonly ordered tests, such as complete blood counts, liver function tests, and cholesterol levels.
Mr. Vergel has advocated for the use of hormones to treat HIV-wasting disease for nearly 40 years, after his own diagnosis of the infection in 1986. After losing 40 pounds, steroids saved his life, he said.
Mr. Vergel said he was shocked to learn about the lack of continuing medical education on AAS for physicians and agreed with Dr. O’Connor that more training is needed for the medical profession. He also recognized that stigma on the part of clinicians is a huge barrier for many AAS users.
“We have to accept the fact that people are using them instead of demonizing them,” Mr. Vergel said. “What I was seeing is that there was so much stigma – and patients would not even talk to their doctors about their use.”
After reviewing Google analytics for his lab’s website and seeing how often “bodybuilder” came up as a search term, he added a panel of labs a year ago that allows AAS users to monitor themselves for adverse events.
Although he doesn’t condone the use of AAS without a medical indication and advises customers to discuss their results with a doctor, “we have to make sure people are reducing their harm or risk,” he said. “That’s really my goal.”
Many health care professionals would disagree with that statement. Dr. Nagata said he was concerned that management of side effects is too complicated. “There are a lot of nuances in the interpretation of these tests.” Arriving at the correct interpretation of the results requires a clinician’s thorough review of each patient’s health history, family history, and mental health history along with lab results.
‘I’m concerned’
In a second article outlining harm-reduction strategies designed to improve care for patients using AAS, Dr. O’Connor and colleagues outlined an approach for talking with patients who are concerned about their health and are seeking guidance from a clinician.
The first step is to work on developing a rapport, and not to demand that patients stop their use of AAS. His recommended opening line is: “I want to be honest with you – I’m concerned.”
The initial interaction is an opportunity to find out why the person uses AAS, what health concerns they have at present, and why they are seeking care. Open-ended questions may reveal concerns that the patient has about fertility or side effects.
Consistent with harm-reduction approaches used for other public health epidemics – such as opioid abuse and blood-borne pathogens among people who inject drugs – follow-up visits can include nonjudgmental discussions about decreasing or stopping their use.
Ultimately, minimizing the harms of AAS use can serve as a bridge to their cessation, but the medical community needs to build up trust with a community of users who currently rely more on each other and the Internet for guidance than their primary care physicians. “We need more education. We’re going to need resources to do it,” Dr. O’Connell said. “And we’re going to have to do it.”
Dr. Phillips and Dr. Nagata have no financial disclosures. Mr. Vergel is the owner and founder of Discounted Labs but reported no other financial conflicts. Dr. O’Connor owns Anabolic Doc but has no additional financial disclosures.

Mr. Vergel said he was shocked to learn about the lack of continuing medical education on AAS for physicians and agreed with Dr. O’Connor that more training is needed for the medical profession. He also recognized that stigma on the part of clinicians is a huge barrier for many AAS users.
“We have to accept the fact that people are using them instead of demonizing them,” Mr. Vergel said. “What I was seeing is that there was so much stigma – and patients would not even talk to their doctors about their use.”
After reviewing Google analytics for his lab’s website and seeing how often “bodybuilder” came up as a search term, he added a panel of labs a year ago that allows AAS users to monitor themselves for adverse events.
Although he doesn’t condone the use of AAS without a medical indication and advises customers to discuss their results with a doctor, “we have to make sure people are reducing their harm or risk,” he said. “That’s really my goal.”
Many health care professionals would disagree with that statement. Dr. Nagata said he was concerned that management of side effects is too complicated. “There are a lot of nuances in the interpretation of these tests.” Arriving at the correct interpretation of the results requires a clinician’s thorough review of each patient’s health history, family history, and mental health history along with lab results.
‘I’m concerned’
In a second article outlining harm-reduction strategies designed to improve care for patients using AAS, Dr. O’Connor and colleagues outlined an approach for talking with patients who are concerned about their health and are seeking guidance from a clinician.
The first step is to work on developing a rapport, and not to demand that patients stop their use of AAS. His recommended opening line is: “I want to be honest with you – I’m concerned.”
The initial interaction is an opportunity to find out why the person uses AAS, what health concerns they have at present, and why they are seeking care. Open-ended questions may reveal concerns that the patient has about fertility or side effects.
Consistent with harm-reduction approaches used for other public health epidemics – such as opioid abuse and blood-borne pathogens among people who inject drugs – follow-up visits can include nonjudgmental discussions about decreasing or stopping their use.
Ultimately, minimizing the harms of AAS use can serve as a bridge to their cessation, but the medical community needs to build up trust with a community of users who currently rely more on each other and the Internet for guidance than their primary care physicians. “We need more education. We’re going to need resources to do it,” Dr. O’Connell said. “And we’re going to have to do it.”
Dr. Phillips and Dr. Nagata have no financial disclosures. Mr. Vergel is the owner and founder of Discounted Labs but reported no other financial conflicts. Dr. O’Connor owns Anabolic Doc but has no additional financial disclosures.

Are ketogenic supplements the key to healthy aging?
A century ago, pediatricians began prescribing for children with intractable seizures the “keto diet,” which they also used to treat diabetes in children and adults. The low-carbohydrate, high-fat meals were designed to induce a near hypoglycemic state, forcing the body to use ketones for fuel instead of glucose.
The strategy fell out of favor after the discovery of insulin in the 1920s and the development of better antiseizure medications. global market for the ketogenic diet topped $11 billion in 2022.
Is it just a fad, or has the public – and science – caught up with the 100-year-old approach?
Although scientists still don’t know why the ketogenic diet was effective for controlling seizures, they have documented the effectiveness of ketogenic diets for the treatment of diabetes and metabolic syndrome. An extensive body of literature has documented their use in athletes, but less is known regarding conditions such as heart disease and dementia.
Although the data are promising, much of the research has been conducted with mice or has come from trials of short-term use in humans. But recently, the National Institutes of Health awarded a $3.5 million federal grant for a double-blind, randomized, placebo-controlled clinical trial to understand the effects of the long-term use of ketone ester supplementation on frailty. Developed 20 years ago, ketone esters are precursor molecules that the body quickly breaks down into ketone bodies when carbohydrates aren’t available.
“We’ve learned so much recently about how ketone bodies interact with aging biology,” John Newman, MD, PhD, of the Buck Institute for Research on Aging in Novato, Calif., and the study’s principal investigator, said in an interview. “And we’re only just starting to translate that out of the laboratory and into human studies to see how we can take advantage of ketone bodies to improve people’s health.”
Researchers from the Ohio State University and the University of Connecticut will also participate in the TAKEOFF (Targeting Aging With Ketone Ester in Older Adults for Function in Frailty) trial, which seeks to recruit a total of 180 people across the three sites.
Dr. Newman, assistant professor at the Buck Institute and associate professor in the division of geriatrics at the University of California, San Francisco, said
One of the common things that happen during aging is that tissues – such as of the heart, brain, and muscle – lose the ability to metabolize glucose effectively. Over time, resistance to insulin can develop.
Researchers can map out areas of the brain affected by Alzheimer’s disease, for example, by assessing where patients’ glucose uptake drops. In heart failure, the heart has difficulty obtaining enough energy from glucose and instead burns fats and ketone bodies.
How might ketones affect frailty in the elderly?
As a practicing geriatrician, Dr. Newman measures frailty by evaluating patients’ strength, endurance, and how they react to stresses. He and his colleagues believe certain molecular and cellular changes may make patients more likely to fall, to recover more slowly from surgery, or to lose mobility.
The main hypothesis of the TAKEOFF study is “that if you target these fundamental mechanisms of aging, you would be able to impact many different diseases of aging across different organ systems.”
Dr. Newman and Brianna Stubbs, DPhil, lead translational scientist at the Buck Institute, are still finishing up the BIKE (Buck Institute Ketone Ester) pilot study, which was the first double-blind, randomized, placebo-controlled study to evaluate the use of ketone ester supplements in adults older than 65 years. “The BIKE study is 12 weeks long. That’s actually the longest that anyone has studied ketone ester supplements in humans,” Dr. Stubbs said. The results will help them firm up the protocol for the TAKEOFF trial, which will likely treat patients for up to 24 weeks.
The primary outcome measure at all three study sites will be leg press strength. Researchers will also assess a variety of secondary outcomes that cover geriatric and cognitive function – measures such as gait speed and walking endurance, cognitive tests, and quality of life. And at the Buck, Dr. Newman and Dr. Stubbs will be evaluating the use of biomarkers that are often available in clinical labs – insulin, C-reactive protein, cystatin, and natriuretic peptide tests – for use as outcome measures that are responsive to treatment interventions and that can be used to track outcomes in future research on aging.
To achieve the goal of looking broadly at different organ systems likely to be affected by ketogenic supplements, they have assembled a team of coinvestigators with wide-ranging expertise in ketone and aging research.
Jeff Volek, PhD, professor in the department of human sciences at the Ohio State University, in Columbus, has contributed extensively to the literature on the use of ketogenic diets and supplements in a variety of populations, such as endurance athletes and patients with insulin resistance or diabetes.
Dr. Volek has demonstrated that ketones can have an anticatabolic effect on muscle tissue. “They could help offset some of the muscle loss with aging, which would in turn improve their physical functioning and ability to do daily activities,” he said.
The anti-inflammatory property of ketones may provide another benefit to older people. They can reduce oxidative stress, which is considered one of the chief pathologic mechanisms responsible for conditions such as heart disease, Alzheimer’s disease, asthma, and arthritis.
In addition to the main study outcomes, Dr. Volek’s lab will study muscle physiology by performing biopsies at baseline and after consumption of ketogenic supplements to assess metabolic changes in muscle cells as they consume energy. Study participants will also undergo MRIs to detect subtle changes in muscle size before and after treatment.
From elite athletes to everyday agers
As a graduate student in Dr. Volek’s lab, Jenna Bartley, PhD, studied the effects of a ketogenic diet on elite athletes. But her work has taken a turn. Now an assistant professor in the department of immunology and the center on aging at the University of Connecticut in Farmington, she focuses on how immune responses and physical function decline with age.
“Ketogenic diets and the main ketone bodies – mainly beta-hydroxybutyrate – have been shown to have really powerful influences on a lot of things that go wrong with aging,” Dr. Bartley said. The decline in immune function in the elderly is not isolated to one cell type or even one arm of the immune system. There is reason to believe ketone supplementation could improve immune function.
“T cells really love ketones for energy,” Dr. Bartley said. Some data show that production of ketone bodies is impaired in individuals with severe SARS-CoV-2 infection. Mouse models of SARS-CoV-2 infection have found that ketogenic diets led to improvement in the response to antiviral therapy.
In her lab, she’ll assess serum markers of inflammation in patients, as well as cytokine secretion following stimulation of T cells. T cells in culture from older people produce more inflammatory cytokines than those from younger people, leading to a dysfunctional immune response. Dr. Bartley is curious to see whether ketones can fix that. Additional work will include single-cell RNA sequencing of different classes of immune cells to investigate how ketones might change metabolic pathways.
Why use ketogenic supplements instead of having people consume ketogenic diets? “There are no cheat days in the keto diet,” Dr. Bartley said. Administering the diet requires intense supervision of research participants to enforce adherence. Use of supplements will improve compliance and likely make any findings translatable to more of the population, she said.
Drawbacks of the initial formulations of ketone esters, first developed 20 years ago, included high cost and terrible taste. Dr, Stubbs, a former world class rowing champion who competed in the Ironman World Championship last year, has firsthand experience with them as a research participant.
“It tasted like drinking nail polish,” she said. Recent advances in manufacturing have made them cheaper – roughly $5 per day – and more palatable, enabling research studies such as TAKEOFF.
For Dr. Newman, the studies are early building blocks in the emerging field of geroscience, which aims to translate fundamental mechanisms of aging into therapies to treat disease.
“We’re hoping that this will be an example of a proof-of-concept geroscience study that will really help to translate ketone body biology out of the laboratory and hopefully into a diversity of clinical applications,” he said. “There’s a lot we don’t understand still about the molecular mechanisms of frailty.”

New clues to an old mystery: Recent gains in endometriosis
In 1927, American gynecologist John Sampson published his theory of the etiology of endometriosis, postulating that retrograde flow of endometrial debris flows backward through the fallopian tubes during menses into the peritoneal cavity. Dr. Sampson’s notion remains the main paradigm today, mentioned still in recent articles on the topic, but it has a flaw: Although the theory may account for how endometrial tissue escapes the uterus, a 1984 study revealed that this phenomenon occurs in 90% of women. Why, then, do only 10% of women suffer from endometriosis?
Endometriosis describes a condition in which endometrial tissue lining the uterus is found outside the uterus. The disease can be painful, even crippling. As many as 30% of women in their reproductive years who have endometriosis are infertile as a consequence. The hallmarks of the condition are superficial peritoneal lesions of varying color, cysts in the ovaries, deeper nodules accompanied by scarring and adhesion, primarily in the pelvis but sometimes appearing outside the pelvis. The syndrome can be challenging to identify, requiring laparoscopy for definitive diagnosis.
John Sampson aside, scientists have struggled for the past century to identify the cause, or causes, of endometriosis. Hormones clearly play a role in its development, and women with endometriosis have an elevated risk of clear-cell and endometrioid ovarian cancer and autoimmune diseases. Immunodeficiency also could be to blame, if a faulty immune system fails to find and remove endometrial tissue outside of the uterus. A class of chemicals known as endocrine disruptors have been linked to endometriosis, but not definitively. Twin studies have demonstrated that as many as 50% of cases have a genetic basis, while mice with surgically induced endometriosis have been found to have a higher ratio of harmful to beneficial bacteria in their gut.
Several studies published this year point to new insights into the old mystery – with possible implications for ways to treat the disorder.
Perhaps the most surprising came out earlier this year in Science Translational Medicine, as a team of researchers in Japan reported that invasive infection by bacteria of the genus Fusobacterium may cause at least some cases of endometriosis.
Is Fusobacterium the new Helicobacter pylori?
The researchers, from Nagoya University, are the first to suggest that not only might a single bacterial genus cause endometriosis, but that antibiotic treatment could prevent progression of the disease. Using endometrial tissue obtained from 79 women undergoing hysterectomy for endometriosis and 76 women undergoing hysterectomy for other reasons (such as cervical cancer), the team started with gene expression profiling to explore differences between the two sets of samples.
They uncovered an interesting chain of cellular events: macrophages found in endometriotic lesions were secreting transforming growth factor-beta (TGF-beta). TGF-beta in turn stimulated high levels of expression of a gene called TAGLN in fibroblast cells from women with endometriosis but not in fibroblasts from women without endometriosis.
Turning on TAGLN transformed these previously inactive cells into active myofibroblasts, leading to increased proliferation, mobility, and attachment to mesothelial cells, the layer of cells that line body cavities and internal organs. In short, they identified some key players in an environment that seemed very favorable to the development of endometriosis.
“So, the question is: Why are macrophages activated?” said Yutaka Kondo, MD, PhD, the senior author of the study and a professor in the division of cancer biology at the Nagoya (Japan) University Graduate School of Medicine. “We think that there are always bacteria in the endometrium.”
After reviewing data from a previously published study, they used quantitative polymerase chain reaction to rule out one candidate, Erysipelothrix, but scored on their next attempt, identifying Fusobacterium species in endometrial tissue from 64% of the women with endometriosis, compared with fewer than 10% of the controls.
To confirm that the bacteria could cause disease and were not simply bystanders, Dr. Kondo’s team turned to a mouse model for endometriosis, in which endometrial cells are surgically removed from the uteri of mice and injected into the peritoneum of recipient mice, leading to the formation of endometriotic lesions. When mice received further injections of uterine tissue from mice that were infected with F. nucleatum, their lesions were more numerous when compared with mice that received injections of uninfected uterine tissue. Furthermore, antibiotic treatment with metronidazole or chloramphenicol immediately after surgery largely prevented progression to endometriosis, Dr. Kondo and his colleagues reported.
Dr. Kondo likened this relationship between Fusobacterium and endometriosis to that of the link between Helicobacter pylori and peptic ulcers but acknowledged that he doesn’t have all the answers.
“We need more clinical trials, and also we have to know what kind of treatment might be the most effective for the treatment of endometriosis,” Dr. Kondo said, pointing out that other therapies should still be pursued in addition to antibiotics, as not all the samples from women with endometriosis harbored Fusobacterium. “It might be possible that other mechanisms are also involved.”
Don’t write off gut microbiota
Ramakrishna Kommagani, PhD, associate professor of pathology and immunology at Baylor College of Medicine in Houston, agreed. “Endometriosis is a complex disease, which appears to be impacted by many factors, including genetic, epigenetic, and environmental factors,” Dr. Kommagani said.
In earlier work, Dr. Kommagani colleagues showed that broad-spectrum antibiotics could reduce disease progression in mice with a mouse model similar to the one Dr. Kondo’s group used.
A key difference between his work and Dr. Kondo’s is his focus on gut microbiota, whereas the Japanese team looked at bacteria in the vagina and endometrium. But Dr. Kommagani said he thinks both could play a role. “Maybe the vaginal microbiome might have a direct impact on disease similar to what we showed on the gut,” he said.
But he said at least part of the answer to why some women develop endometriosis may have to do more with the balance of beneficial and harmful bacteria in the gut rather than because of a single family of microbes like Fusobacterium.
Most recently, by dovetailing a mouse model for inducing endometriosis in mice treated with antibiotics to deplete their gut microbiome, Dr. Kommagani’s lab expanded on its previous work: They showed that the animals developed fewer of the typical lesions seen in endometriosis than those that did not receive antibiotics before all of the mice underwent the surgical procedure used by researchers to induce endometriosis – possibly because they had no bacteria in their gut triggering the inflammatory response required for the development of endometriosis.
But after oral feedings with fecal matter from mice without endometriosis, the microbiota-depleted rodents began developing lesions typical of endometriosis, suggesting that altered gut flora from mice with endometriosis appeared to promote the disorder. Meanwhile, their microbiota-depleted counterparts who were fed fecal matter from mice without endometriosis did not develop the typical lesions.
Dr. Kommagani’s team then compared metabolites from bacteria in stool from mice with and without endometriosis and investigated the in vitro effect of these metabolites on cells from human endometriotic lesions. One of them, quinic acid, increased the proliferation of human endometriotic epithelial cells.
“Some metabolites such as fiber-derived short-chain fatty acids have beneficial effects; they inhibit the disease,” Dr. Kommagani said. “But maybe an amino acid derivative such as quinic acid, [may] promote disease, and these are generated because there is a gut dysbiosis.”
This statement hints at some of the possible therapeutic approaches for endometriosis, such as a high-fiber diet to promote healthy gut flora, or perhaps antibiotics to eradicate unhealthy bacteria. But as with other conditions that have been linked to dysbiosis, like inflammatory bowel disease, use of antibiotics is a bit like balancing on a tightrope; although antibiotics may remove harmful bacteria, their use may negatively affect the beneficial bacteria.
Clues in genetic variants
Krina Zondervan, DPhil, professor and head of the department of reproductive and genomic epidemiology at the University of Oxford (England), focuses on genomic, molecular, and epidemiologic approaches to understanding endometriosis.
In her most recent paper, published earlier this year in Nature Genetics Dr. Zondervan and colleagues started with a meta-analysis of 29 genome-wide association studies involving over 200,00 cases of endometriosis from Europe, Australia, the United States, and Japan. They identified 42 genetic regions linked to endometriosis, nearly four times the number previously identified.
“It’s one thing identifying risk variants and the next question is, okay, well, what do those variants actually do in terms of biology?” Dr. Zondervan said. The Oxford team next explored how the identified genetic variants affect gene expression and the proteins generated, drawing on previously collected data on gene expression from samples of human blood and endometrial and uterine tissue.
They found many of the genes implicated in the risk for endometriosis code for proteins that affect sex hormones, uterine development, transformation of healthy cells into cancerous tissue, inflammatory adhesion molecules, and factors promoting development of new blood vessels. All of that, she said, explains how a few endometrial cells making their way into the pelvis can attach to ovaries, ligaments, and peritoneal surfaces; proliferate; and acquire a blood supply to ensure their survival.
“We were able to identify a whole host of things that were likely causal to the disease,” Dr. Zondervan said. And that finding led to her next question: “Are there particular genes or areas around them that can be targeted with certain medications?”
The surprising answer was that several of the genes linked to endometriosis share pathways with clinical syndromes that often occur in women with endometriosis. Many of these are chronic pain conditions – such as migraines, headaches, and back pain – but also include inflammatory illnesses such as asthma and osteoarthritis.
As Dr. Zondervan explained, “A lot of the variance that we see for endometriosis is also experienced for low back pain and migraine, and that clearly has something to do with pain perception and pain mechanisms.”
A connection between the development of neural pathways and endometriosis has been proposed before, as researchers have found that endometriotic lesions can develop their own nerve supply, creating a direct interaction between the lesions and the central nervous system. And some clinicians have been employing treatment strategies that employ multimodal therapies – employing physical therapists, mental health practitioners, nutritionists, and pain specialists prior to and following surgical removal of lesions – to improve overall success rates of treatment.
But Dr. Zondervan’s team is the first to uncover an important clue about how this happens.
The study findings also provide solid clues to researchers about which genes and proteins to focus on for drug target discovery. In particular, the gene pathways shared by endometriosis and various pain conditions could allow for repurposing of drugs developed for other conditions for treating endometriosis, reported Dr. Zondervan.
Dr. Zondervan’s other important conclusion, echoed by Dr. Kondo and Dr. Kommagani, is that endometriosis is not one disease. Rather, it appears to be akin to cancer in terms of the heterogeneity of how it presents and the different subtypes of diseases. The Oxford study corroborated this belief, identifying certain genes that were closely associated with cystic lesions in ovaries, but failing to turn up a genetic link to other types of lesions in the pelvis long considered to be part of the spectrum of endometriosis disease.
Dr. Zondervan agreed that the potential link with Fusobacterium is a fascinating area given the critical role of inflammation in the pathogenesis of endometriosis, although she’d like to see the work replicated with larger sample sizes. “From a personal point of view, I’d be really fascinated to see how genetics interplays with this,” she added.
What’s next?
The chief limitation of human studies looking at mechanisms of endometriosis is that they are correlational: Tissue samples are collected from women with and without endometriosis, often through an invasive procedure such as laparoscopy or biopsy, at one point in time.
Currently, the best tools for proving causation are animal models of endometriosis, such as the those used by Dr. Kondo’s and Dr. Kommagani’s teams.Better diagnostic tools would solve that problem. The ultimate goal is a noninvasive test for endometriosis that would allow clinicians to follow women over time and permit the monitoring of disease progression, or regression, without the need for painful procedures. Such a diagnostic tool would facilitate rigorous longitudinal studies evaluating mechanisms of disease, as well as monitoring outcomes of clinical trials of new treatments.
Could stool samples be the answer?
The Japanese team found that women harboring Fusobacterium in endometrial tissue also had Fusobacterium in vaginal samples taken at the time of their hysterectomy – and stool samples can pick up changes in the gut microbiome.
“Vaginal swab or stool tests are probably the best and easiest for noninvasive early detection,” Dr. Kommagani said.
Spit tests for DNA would be even easier to obtain. Polygenic risk scores could be developed to estimate an individual’s risk of disease based on the number of variants, but Dr. Zondervan cautioned that not all the genes that account for endometriosis are known.
“The things that we found altogether explain about 5% of disease variability, basically – which is still not an awful lot,” she said.
Dr. Kondo’s work was supported by the Grant-in-Aid for Scientific Research, the Japan Society for the Promotion of Science, and the Research Grant of the Princess Takamatsu Cancer Research Fund. A patent method for detecting bacteria of genus Fusobacterium in order to diagnose endometriosis (WO2023/ 042714), was submitted (international publication date, March 23, 2023).
Dr. Kommagani’s work was funded, in part, by National Institutes of Health/National Institute of Child Health and Human Development grants R01HD102680, R01HD065435, and R00HD080742.

In 1927, American gynecologist John Sampson published his theory of the etiology of endometriosis, postulating that retrograde flow of endometrial debris flows backward through the fallopian tubes during menses into the peritoneal cavity. Dr. Sampson’s notion remains the main paradigm today, mentioned still in recent articles on the topic, but it has a flaw: Although the theory may account for how endometrial tissue escapes the uterus, a 1984 study revealed that this phenomenon occurs in 90% of women. Why, then, do only 10% of women suffer from endometriosis?
Endometriosis describes a condition in which endometrial tissue lining the uterus is found outside the uterus. The disease can be painful, even crippling. As many as 30% of women in their reproductive years who have endometriosis are infertile as a consequence. The hallmarks of the condition are superficial peritoneal lesions of varying color, cysts in the ovaries, deeper nodules accompanied by scarring and adhesion, primarily in the pelvis but sometimes appearing outside the pelvis. The syndrome can be challenging to identify, requiring laparoscopy for definitive diagnosis.
John Sampson aside, scientists have struggled for the past century to identify the cause, or causes, of endometriosis. Hormones clearly play a role in its development, and women with endometriosis have an elevated risk of clear-cell and endometrioid ovarian cancer and autoimmune diseases. Immunodeficiency also could be to blame, if a faulty immune system fails to find and remove endometrial tissue outside of the uterus. A class of chemicals known as endocrine disruptors have been linked to endometriosis, but not definitively. Twin studies have demonstrated that as many as 50% of cases have a genetic basis, while mice with surgically induced endometriosis have been found to have a higher ratio of harmful to beneficial bacteria in their gut.
Several studies published this year point to new insights into the old mystery – with possible implications for ways to treat the disorder.
Perhaps the most surprising came out earlier this year in Science Translational Medicine, as a team of researchers in Japan reported that invasive infection by bacteria of the genus Fusobacterium may cause at least some cases of endometriosis.
Is Fusobacterium the new Helicobacter pylori?
The researchers, from Nagoya University, are the first to suggest that not only might a single bacterial genus cause endometriosis, but that antibiotic treatment could prevent progression of the disease. Using endometrial tissue obtained from 79 women undergoing hysterectomy for endometriosis and 76 women undergoing hysterectomy for other reasons (such as cervical cancer), the team started with gene expression profiling to explore differences between the two sets of samples.
They uncovered an interesting chain of cellular events: macrophages found in endometriotic lesions were secreting transforming growth factor-beta (TGF-beta). TGF-beta in turn stimulated high levels of expression of a gene called TAGLN in fibroblast cells from women with endometriosis but not in fibroblasts from women without endometriosis.
Turning on TAGLN transformed these previously inactive cells into active myofibroblasts, leading to increased proliferation, mobility, and attachment to mesothelial cells, the layer of cells that line body cavities and internal organs. In short, they identified some key players in an environment that seemed very favorable to the development of endometriosis.
“So, the question is: Why are macrophages activated?” said Yutaka Kondo, MD, PhD, the senior author of the study and a professor in the division of cancer biology at the Nagoya (Japan) University Graduate School of Medicine. “We think that there are always bacteria in the endometrium.”
After reviewing data from a previously published study, they used quantitative polymerase chain reaction to rule out one candidate, Erysipelothrix, but scored on their next attempt, identifying Fusobacterium species in endometrial tissue from 64% of the women with endometriosis, compared with fewer than 10% of the controls.
To confirm that the bacteria could cause disease and were not simply bystanders, Dr. Kondo’s team turned to a mouse model for endometriosis, in which endometrial cells are surgically removed from the uteri of mice and injected into the peritoneum of recipient mice, leading to the formation of endometriotic lesions. When mice received further injections of uterine tissue from mice that were infected with F. nucleatum, their lesions were more numerous when compared with mice that received injections of uninfected uterine tissue. Furthermore, antibiotic treatment with metronidazole or chloramphenicol immediately after surgery largely prevented progression to endometriosis, Dr. Kondo and his colleagues reported.
Dr. Kondo likened this relationship between Fusobacterium and endometriosis to that of the link between Helicobacter pylori and peptic ulcers but acknowledged that he doesn’t have all the answers.
“We need more clinical trials, and also we have to know what kind of treatment might be the most effective for the treatment of endometriosis,” Dr. Kondo said, pointing out that other therapies should still be pursued in addition to antibiotics, as not all the samples from women with endometriosis harbored Fusobacterium. “It might be possible that other mechanisms are also involved.”
Don’t write off gut microbiota
Ramakrishna Kommagani, PhD, associate professor of pathology and immunology at Baylor College of Medicine in Houston, agreed. “Endometriosis is a complex disease, which appears to be impacted by many factors, including genetic, epigenetic, and environmental factors,” Dr. Kommagani said.
In earlier work, Dr. Kommagani colleagues showed that broad-spectrum antibiotics could reduce disease progression in mice with a mouse model similar to the one Dr. Kondo’s group used.
A key difference between his work and Dr. Kondo’s is his focus on gut microbiota, whereas the Japanese team looked at bacteria in the vagina and endometrium. But Dr. Kommagani said he thinks both could play a role. “Maybe the vaginal microbiome might have a direct impact on disease similar to what we showed on the gut,” he said.
But he said at least part of the answer to why some women develop endometriosis may have to do more with the balance of beneficial and harmful bacteria in the gut rather than because of a single family of microbes like Fusobacterium.
Most recently, by dovetailing a mouse model for inducing endometriosis in mice treated with antibiotics to deplete their gut microbiome, Dr. Kommagani’s lab expanded on its previous work: They showed that the animals developed fewer of the typical lesions seen in endometriosis than those that did not receive antibiotics before all of the mice underwent the surgical procedure used by researchers to induce endometriosis – possibly because they had no bacteria in their gut triggering the inflammatory response required for the development of endometriosis.
But after oral feedings with fecal matter from mice without endometriosis, the microbiota-depleted rodents began developing lesions typical of endometriosis, suggesting that altered gut flora from mice with endometriosis appeared to promote the disorder. Meanwhile, their microbiota-depleted counterparts who were fed fecal matter from mice without endometriosis did not develop the typical lesions.
Dr. Kommagani’s team then compared metabolites from bacteria in stool from mice with and without endometriosis and investigated the in vitro effect of these metabolites on cells from human endometriotic lesions. One of them, quinic acid, increased the proliferation of human endometriotic epithelial cells.
“Some metabolites such as fiber-derived short-chain fatty acids have beneficial effects; they inhibit the disease,” Dr. Kommagani said. “But maybe an amino acid derivative such as quinic acid, [may] promote disease, and these are generated because there is a gut dysbiosis.”
This statement hints at some of the possible therapeutic approaches for endometriosis, such as a high-fiber diet to promote healthy gut flora, or perhaps antibiotics to eradicate unhealthy bacteria. But as with other conditions that have been linked to dysbiosis, like inflammatory bowel disease, use of antibiotics is a bit like balancing on a tightrope; although antibiotics may remove harmful bacteria, their use may negatively affect the beneficial bacteria.

Here’s how we can rebuild trust in vaccines
When people ask Paul Offit, MD, what worries him the most about the COVID-19 pandemic, he names two concerns. “One is the lack of socialization and education that came from keeping kids out of school for so long,” Dr. Offit said in a recent interview. “And I think vaccines have suffered.”
Dr. Offit is director of the Vaccine Education Center and a professor of pediatrics at Children’s Hospital of Philadelphia. He has watched with alarm as the American public appears to be losing faith in the lifesaving vaccines the public health community has worked hard to promote. The Centers for Disease Control and Prevention estimates that the proportion of kids entering kindergarten who have received state-required vaccines dipped to 94% in the 2020-2021 school year – a full point less than the year before the pandemic – then dropped by another percentage point, to 93%, the following year.
Although a couple of percentage points may sound trivial, were only 93% of kindergarteners to receive the vaccine against measles, mumps, and rubella (MMR), approximately 250,000 vulnerable 5-year-olds could spark the next big outbreak, such as the recent measles outbreaks in Ohio and Minnesota.
Dr. Offit is one of many public health officials and clinicians who are working to reverse the concerning trends in pediatric vaccinations.
“I just don’t want to see an outbreak of something that we could have avoided because we were not protected enough,” Judith Shlay, MD, associate director of the Public Health Institute at Denver Health, said.
Official stumbles in part to blame
Disruptions in health care from the COVID-19 pandemic certainly played a role in the decline. Parents were afraid to expose their children to other sick kids, providers shifted to a telehealth model, and routine preventive care was difficult to access.
But Dr. Offit also blamed erosion of trust on mistakes made by government and public health institutions for the alarming trend. “I think that health care professionals have lost some level of trust in the Food and Drug Administration and CDC.”
He cited as an example poor messaging during a large outbreak in Massachusetts in summer 2021, when the CDC published a report that highlighted the high proportion of COVID-19 cases among vaccinated people. Health officials called those cases “breakthrough” infections, although most were mild or asymptomatic.
Dr. Offit said the CDC should have focused the message instead on the low rate (1%) of hospitalizations and the low number of deaths from the infections. Instead, they had to walk back their promise that vaccinated people didn’t need to wear masks. At other times, the Biden administration pressured public health officials by promising to make booster shots available to the American public when the FDA and CDC felt they lacked evidence to recommend the injections.
Rupali Limaye, PhD, an associate professor of international health at the Bloomberg School of Public Health at Johns Hopkins University, Baltimore, studies vaccine behavior and decision-making. She would go a step further in characterizing the roots of worsening vaccine hesitancy.
“In the last 20 years, we’ve seen there’s less and less trust in health care providers in general,” Dr. Limaye said. “More people are turning to their social networks or social contacts for that kind of information.” In the maelstrom of the COVID-19 pandemic, digital social networks facilitated the spread of misinformation about COVID-19 faster than scientists could unravel the mysteries of the disease.
“There’s always been this underlying hesitancy for some people about vaccines,” Dr. Shlay said. But she has noticed more resistance to the COVID-19 vaccine from parents nervous about the new mRNA technology. “There was a lot of politicization of the vaccine, even though the mRNA vaccine technology has been around for a long time,” she said.
Multipronged approaches
Dr. Shlay is committed to restoring childhood vaccination uptake to prepandemic levels now that clinics are open again. To do so, she is relying on a combination of quality improvement strategies and outreach to undervaccinated populations.
Denver Health, for instance, offers vaccinations at any inpatient or outpatient visit – not just well-child visits – with the help of alerts built into their electronic health records that notify clinicians if a patient is due for a vaccine.
COVID-19 revealed marked health inequities in underserved communities as Black, Hispanic, and people from other minority communities experienced higher rates of COVID-19 cases and deaths, compared with White people. The Public Health Institute, which is part of Denver Health, has responded with vaccine outreach teams that go to schools, shelters, churches, and community-based organizations to vaccinate children. They focus their efforts on areas where immunization rates are low. Health centers in schools throughout Colorado vaccinate students, and the Public Health Institute partners with Denver-area public schools to provide vaccines to students in schools that don’t have such centers. (They also provide dental care and behavioral health services.)
But it is unlikely that restoring clinic operations and making vaccines more accessible will fill the gap. After 3 years of fear and mistrust, parents are still nervous about routine shots. To help clinicians facilitate conversations about vaccination, Denver Health trains providers in communication techniques using motivational interviewing (MI), a collaborative goal-oriented approach that encourages changes in health behaviors.
Dr. Shlay, who stressed the value of persistence, advised, “Through motivational interviewing, discussing things, talking about it, you can actually address most of the concerns.”
Giving parents a boost in the right direction
That spirit drives the work of Boost Oregon, a parent-led nonprofit organization founded in 2015 that helps parents make science-based decisions for themselves and their families. Even before the pandemic, primary care providers needed better strategies for addressing parents who had concerns about vaccines and found themselves failing in the effort while trying to see 20 patients a day.
For families that have questions about vaccines, Boost Oregon holds community meetings in which parents meet with clinicians, share their concerns with other parents, and get answers to their questions in a nonjudgmental way. The 1- to 2-hour sessions enable deeper discussions of the issues than many clinicians can manage in a 20-minute patient visit.
Boost Oregon also trains providers in communication techniques using MI. Ryan Hassan, MD, a pediatrician in private practice who serves as the medical director for the organization, has made the approach an integral part of his day. A key realization for him about the use of MI is that if providers want to build trust with parents, they need to accept that their role is not simply to educate but also to listen.
“Even if it’s the wildest conspiracy theory I’ve ever heard, that is my opportunity to show them that I’m listening and to empathize,” Dr. Hassan said.
His next step, a central tenet of MI, is to make reflective statements that summarize the parent’s concerns, demonstrate empathy, and help him get to the heart of their concerns. He then tailors his message to their issues.
Dr. Hassan tells people who are learning the technique to acknowledge that patients have the autonomy to make their own decisions. Coercing them into a decision is unhelpful and potentially counterproductive. “You can’t change anyone else’s mind,” he said. “You have to help them change their own mind.”
Dr. Limaye reinforced that message. Overwhelmed by conflicting messages on the internet, people are just trying to find answers. She trains providers not to dismiss patients’ concerns, because dismissal erodes trust.
“When you’re dealing with misinformation and conspiracy, to me, one thing to keep in mind is that it’s the long game,” Dr. Limaye said, “You’re not going to be able to sway them in one conversation.”
Can the powers of social media be harnessed for pro-vaccine messaging? Dr. Limaye has studied social media strategies to promote vaccine acceptance and has identified several elements that can be useful for swaying opinions about vaccine.
One is the messenger – as people trust their physicians less, “it’s important to find influencers that people might trust to actually spread a message,” she said. Another factor is that as society has become more polarized, interaction with the leadership of groups that hold influence has become key. To promote vaccine acceptance, for example, leaders of moms’ groups on Facebook could be equipped with evidence-based information.
“It’s important for us to reach out and engage with those that are leaders in those groups, because they kind of hold the power,” Dr. Limaye said.
Framing the message is critical. Dr. Limaye has found that personal narratives can be persuasive and that to influence vaccine behavior, it is necessary to tailor the approach to the specific audience. Danish researchers, for example, in 2017 launched a campaign to increase uptake of HPV vaccinations among teenagers. The researchers provided facts about the safety and effectiveness of the vaccine, cited posts by clinicians about the importance of immunization against the virus, and relayed personal stories, such as one about a father who chose to vaccinate his daughter and another about a blogger’s encounter with a woman with cervical cancer. The researchers found that the highest engagement rates were achieved through personal content and that such content generated the highest proportion of positive comments.
According to Dr. Limaye, to change behavior, social media messaging must address the issues of risk perception and self-efficacy. For risk perception regarding vaccines, a successful message needs to address the parents’ questions about whether their child is at risk for catching a disease, such as measles or pertussis, and if they are, whether the child will wind up in the hospital.
Self-efficacy is the belief that one can accomplish a task. An effective message would provide information on where to find free or low-cost vaccines and would identify locations that are easy to reach and that have expanded hours for working parents, Dr. Limaye said.
What’s the best approach for boosting vaccination rates in the post-pandemic era? In the 1850s, Massachusetts enacted the first vaccine mandate in the United States to prevent smallpox, and by the 1900s, similar laws had been passed in almost half of states. But recent polls suggest that support for vaccine mandates is dwindling. In a poll by the Kaiser Family Foundation last fall, 71% of adults said that healthy children should be required to be vaccinated against measles before entering school, which was down from 82% in a similar poll in 2019.
So perhaps a better approach for promoting vaccine confidence in the 21st century would involve wider use of MI by clinicians and more focus by public health agencies taking advantage of the potential power of social media. As Dr. Offit put it, “I think trust is the key thing.”

When people ask Paul Offit, MD, what worries him the most about the COVID-19 pandemic, he names two concerns. “One is the lack of socialization and education that came from keeping kids out of school for so long,” Dr. Offit said in a recent interview. “And I think vaccines have suffered.”
Dr. Offit is director of the Vaccine Education Center and a professor of pediatrics at Children’s Hospital of Philadelphia. He has watched with alarm as the American public appears to be losing faith in the lifesaving vaccines the public health community has worked hard to promote. The Centers for Disease Control and Prevention estimates that the proportion of kids entering kindergarten who have received state-required vaccines dipped to 94% in the 2020-2021 school year – a full point less than the year before the pandemic – then dropped by another percentage point, to 93%, the following year.
Although a couple of percentage points may sound trivial, were only 93% of kindergarteners to receive the vaccine against measles, mumps, and rubella (MMR), approximately 250,000 vulnerable 5-year-olds could spark the next big outbreak, such as the recent measles outbreaks in Ohio and Minnesota.

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

For Sonja O’Leary, MD, higher rates of vaccination against human papillomavirus came with the flip of a switch.
Dr. O’Leary, the interim director of service for outpatient pediatric services at Denver Health and Hospital Authority, and her colleagues saw rates of HPV and other childhood immunizations drop during the COVID-19 pandemic and decided to act. Their health system, which includes 28 federally qualified health centers, offers vaccines at any inpatient or outpatient visit based on alerts from their electronic health record.
“It was actually really simple; it was really just changing our best-practice alert,” Dr. O’Leary said. Beginning in May 2021, and after notifying clinic staff of the impending change, DHHA dropped the alert for first dose of HPV from age 11 to 9.
The approach worked. Compared with the first 5 months of 2021, the percentage of children aged 9-13 years with an in-person visit who received at least one dose of HPV vaccine between June 2021 and August 2022 rose from 30.3% to 42.8% – a 41% increase. The share who received two doses by age 13 years more than doubled, from 19.3% to 42.7%, Dr. O’Leary said.
Frustrated efforts
Although those figures might seem to make an iron-clad case for earlier vaccinations against HPV – which is responsible for nearly 35,000 cases of cancer annually – factors beyond statistics have frustrated efforts to increase acceptance of the shots.
Data published in 2022 from the U.S. Centers for Disease Control and Prevention found that 89.6% of teens aged 13-17 years received at least one dose of tetanus, diphtheria, and acellular pertussis vaccine, and 89% got one or more doses of meningococcal conjugate vaccine. However, only 76.9% had received one or more doses of HPV vaccine. The rate of receiving both doses needed for full protection was much lower (61.7%).
Both the American Academy of Pediatrics and the American Cancer Society now endorse the strategy of offering HPV vaccine as early as age 9, which avoids the need for multiple shots at a single visit and results in more kids getting both doses. In a recent study that surveyed primary care professionals who see pediatric patients, 21% were already offering HPV vaccine at age 9, and another 48% were willing to try the approach.
What was the most common objection to the earlier age? Nearly three-quarters of clinicians said they felt that parents weren’t ready to talk about HPV vaccination yet.
Noel Brewer, PhD, one of the authors of the survey study, wondered why clinicians feel the need to bring up sex at all. “Providers should never be talking about sex when they are talking about vaccine, because that’s not the point,” said Dr. Brewer, the distinguished professor in public health at the University of North Carolina at Chapel Hill. He pointed out that providers don’t talk about the route of transmission for any other vaccine.
Dr. Brewer led a randomized controlled trial that trained pediatric clinicians in the “announcement” strategy, in which the clinician announces the vaccines that are due at that visit. If the parent hesitates, the clinician then probes further to identify and address their concerns and provides more information. If the parent is still not convinced, the clinician notes the discussion in the chart and tries again at the next visit.
The strategy was effective: Intervention clinics had a 5.4% higher rate of HPV vaccination coverage than control clinics after six months. Dr. Brewer and his colleagues have trained over 1,700 providers in the technique since 2020.
A cancer – not STI – vaccine
Although DHHA hasn’t participated in Dr. Brewer’s training, Dr. O’Leary and her colleagues take a similar approach of simply stating which vaccines the child should receive that day. And they talk about HPV as a cancer vaccine instead of one to prevent a sexually transmitted infection.
In her experience, this emphasis changes the conversation. Dr. O’Leary described a typical comment from parents as, “Oh, of course I would give my child a vaccine that could prevent cancer.”
Ana Rodriguez, MD, MPH, an obstetrician, became interested in raising rates of vaccination against HPV after watching too many women battle a preventable cancer. She worked for several years in the Rio Grande Valley along the U.S. border with Mexico, an impoverished rural area with poor access to health care and high rates of HPV infection.
“I would treat women very young – not even 30 years of age – already fighting advanced precancerous lesions secondary to HPV,” said Dr. Rodriguez, an associate professor of Obstetrics & Gynecology at the University of Texas Medical Branch at Galveston.
In 2016, when Texas ranked 47th in the nation for rates of up-to-date HPV vaccination, Dr. Rodriguez helped launch a community-based educational campaign in four rural counties in the Rio Grande Valley using social media, radio, and in-person meetings with school PTA members and members of school boards to educate staff and parents about the need for vaccination against the infection.

Antenatal corticosteroids: Fresh answers to old questions
Giving corticosteroids to pregnant women at risk for preterm birth before 34 weeks of gestational age has been the standard of care since the 1990s, but a few scenarios for their use remain up for debate. Two studies presented this week at the 2023 meeting sponsored by the Society for Maternal–Fetal Medicine provided some fresh insight into the practice that could help clinicians better manage pregnant patients.
Neurodevelopmental outcomes in late preterm
First, should antenatal corticosteroids (ACS) be given to mothers who present with late preterm labor, defined as 34-36 weeks’ gestational age?
A landmark randomized clinical trial published in 2016 demonstrated that use of ACS in mothers in late preterm labor reduced severe respiratory complications. That practice has largely been adopted by clinicians. The only downside, according to the researchers, was that infants whose mothers received steroid therapy were more likely to develop hypoglycemia. The condition is self-limiting, but studies have raised concern about the potential long-term risk of neurocognitive or psychological outcomes in infants with hypoglycemia.
Cynthia Gyamfi-Bannerman, MD, MSc, endowed chair and professor of obstetrics, gynecology, and reproductive sciences at the University of California, San Diego, led the 2016 study. Her team was unable to secure funding for their originally planned follow-up study of the infants 2 years later. But once the American College of Obstetricians and Gynecologists endorsed the practice and more women received ACS in the late preterm period, Dr. Gyamfi-Bannerman and her colleagues felt the need to “follow up the infants just to see what the outcomes are from a neurodevelopmental standpoint,” she said.
Dr. Gyamfi-Bannerman and colleagues recruited children older than age 6 from the original trial whose parents were willing to have them participate in a follow-up study. A total of 949 from the initial 2,831 cohort completed cognitive testing and received assessments for cerebral palsy, social impairment within the autism spectrum, and behavioral and emotional problems.
At the SMFM conference, Dr. Gyamfi-Bannerman reported no differences in the primary outcome of cognitive function between those whose mothers had received a single course of betamethasone and those who did not, or any differences in rates of the other outcomes.
Kathy Zhang-Rutledge, MD, a maternal-fetal medicine specialist who practices with Obstetrix Maternal Fetal Medicine Group of Houston, part of Pediatrix Medical Group, said she was glad to see a study that addressed the potential long-term adverse events associated with ACS in the late preterm period.
“Having this pretty large study – with really good neurological testing results – should help reassure clinicians that this is something they should consider adopting in their practice,” Dr. Zhang-Rutledge said.
Are boosters better?
The second unresolved question was if a repeat course of ACS should be administered when a woman at risk for preterm birth receives a course of steroids but does not deliver in the following 7 days.
Any benefits to the initial course of ACS wear off after a week. As a result, clinicians often give booster courses 7 days after the first dose if the infant is likely to be delivered in the following week. A 2009 study showed this approach may protect infants from respiratory problems, but data on long-term outcomes have been weak.
ACOG guidelines say to “consider” a booster dose in women who are less than 34 weeks’ gestation at risk for preterm delivery within 7 days.
The exception is when the mother already has experienced preterm prelabor rupture of membranes (PPROM), because ACS may increase the risk for infection for both mother and child. ACOG doesn’t take a stand on use of booster doses for PPROM, citing a lack of data to show that potential benefits outweigh the potential risks of this approach.
A recent multicenter, double-blinded, randomized clinical trial attempted to fill that void in knowledge. Between 2016 and 2022, 194 women with PPROM and gestational age less than 32 weeks who had received an initial ACS course at least 7 days prior to randomization received a booster course of ACS or saline placebo.
“Our primary outcome was designed to be like the prior rescue study (in 2009) that we did with patients with intact membranes,” said Andrew Combs, MD, PhD, a maternal-fetal medicine specialist at Pediatrix Medical Group in Sunrise, Fla., who participated in the earlier study. “It was a composite of neonatal morbidity that was any one of a variety of outcomes including respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and neonatal death.”
The primary outcome occurred in 64% of women who received booster ACS and 66% with placebo (odds ratio, 0.82; 95% confidence interval, 0.43-1.57), according to Dr. Combs, who presented the findings at SMFM.
Although the study was not powered to detect significant differences in specific outcomes, the rate of neonatal sepsis was not higher in the ACS group, suggesting that ACS may be safe if membranes have ruptured, the researchers reported. But because the booster course of ACS did not prevent respiratory morbidity, clinicians may wonder what to do with the findings.
Niraj Chavan, MD, an associate professor in the department of obstetrics, gynecology, and women’s health at Saint Louis University, said he was unsure how the study would affect clinical practice.
The relatively small sample number of patients prevented analysis of specific outcomes and subgroup analyses of important variables such as race, ethnicity, gestational age, and other comorbid conditions in the mothers, he said. So clinicians still must weigh potential risks and benefits on a case-by-case basis.
“You have to think about it in buckets,” he said, “One is conditions that would increase the risk for neonatal morbidity. The other is the risk for infection, both for the mom and the baby.”
But for Dr. Combs, the interpretation of the findings was simpler: “We concluded that there’s no indication to give a booster course of steroids after a week has elapsed in patients with ruptured membranes.”
The study presented by Dr. Gyamfi-Bannerman was funded by the National Institute of Child Health and Human Development. The study presented by Dr. Combs was funded by MEDNAX Center for Research, Education, and Quality, which in 2022 was renamed Pediatrix Center for Research, Education,and Quality. Dr. Combs is an employee of Pediatrix Medical Group but has no conflicts of interest. Dr. Gyamfi-Bannerman, Dr. Zhang-Rutledge, and Dr. Chavan report no relevant financial relationships.

The study presented by Dr. Gyamfi-Bannerman was funded by the National Institute of Child Health and Human Development. The study presented by Dr. Combs was funded by MEDNAX Center for Research, Education, and Quality, which in 2022 was renamed Pediatrix Center for Research, Education,and Quality. Dr. Combs is an employee of Pediatrix Medical Group but has no conflicts of interest. Dr. Gyamfi-Bannerman, Dr. Zhang-Rutledge, and Dr. Chavan report no relevant financial relationships.

FROM THE PREGNANCY MEETING
Vacuum device for postpartum hemorrhage works well in real world
Postpartum hemorrhage is the leading cause of maternal mortality worldwide, accounting for 25% of deaths from obstetric causes. Although balloon tamponade has been widely used to manage uncontrolled postpartum bleeding, a recent evaluation of an intrauterine vacuum-induced hemorrhage control device demonstrated impressive safety and effectiveness, researchers reported at the meeting sponsored by the Society for Maternal-Fetal Medicine.
“It’s exciting to see new technology and new potential treatment modalities. We just don’t have that many tools in our toolkit right now,” said Dena Goffman, MD, professor of women’s health and obstetrics and gynecology and vice chair of quality and patient safety at Columbia University’s Irving Medical Center, in New York, who presented the findings.
Dr. Goffman led an earlier multicenter prospective single-arm treatment study of the Jada System, a vacuum device marketed by Organon. The U.S. Food and Drug Administration approved use of the Jada System in October 2020.
Dr. Goffman said she and her colleagues felt “a next logical step would be to see what happens with real-world use.” In the new study, researchers at 16 U.S. medical centers reviewed medical charts of 800 women who underwent treatment with the Jada System between October 2020 and April 2022.
Treatment was successful in 92.5% of the vaginal births (n = 530) and 83.7% of the cesarean births (n = 270), similar to the results of the initial treatment trial that led to FDA approval, according to the researchers. For both types of delivery, bleeding was controlled in less than 5 minutes for most patients. Three serious adverse events were identified that could have been related to use of the device (two in vaginal births, one in cesarean birth), they reported.
Although the study was not designed to directly compare the Jada System with balloon tamponade, in a recent meta-analysis, it was estimated that tamponade controls postpartum hemorrhage in roughly 87% of cases, with complication rates in as many as 6.5% among women who undergo the procedure.
Dr. Goffman pointed out additional benefits. The vacuum device typically must stay in place for less time (3.1 hours for vaginal birth and 4.6 hours for cesarean birth) than balloon tamponade, allowing women to recover more quickly. In the initial trial, which Dr. Goffman helped conduct, 98% of clinicians reported that the device was easy to use, which increases its attractiveness in lower-income countries. Dr. Goffman felt that the device “has potential for huge impact” in those countries, given the high rates of maternal morbidity and mortality in these areas.
Amber Samuel, MD, medical director of OBSETRIX Maternal Fetal Medicine Specialists of Houston, said the device recently became available in the hospitals in which she works, and she has used the Jada System several times. Like Dr. Goffman, she was excited to have a new tool for treating a life-threatening condition.
Although the device has been on the market for more than 2 years, Dr. Samuel felt clinicians who were reluctant to adopt a new technology would be reassured by the findings.
“We should make sure that it’s effective, and we should know what the safety profile is,” said Dr. Samuel, adding that “the more data we have, the more we’re able to counsel patients and work this into our protocols for what is a really common obstetric problem.”
Both Dr. Goffman and Dr. Samuel agreed that more data, ideally from randomized clinical trials, are needed to convince professional groups such as the American College of Obstetricians and Gynecologists to state a clear preference for use of vacuum-induced hemorrhage control devices over balloon tamponade.
“We should be supporting further investigation,” Dr. Goffman said, “but for people who have this tool available to them now, I think they can feel confident in using it.”
The study was funded by Alydia Health, the manufacturer of the Jada System. Alydia Health was acquired by Organon in 2021. Study sites received research-related financial support, but none of the authors received direct payments from Alydia Health/Organon. Dr. Goffman serves on the scientific advisory board of Alydia Health/Organon. Dr. Samuel has disclosed no relevant financial relationships.

FROM THE PREGNANCY MEETING
Should pediatricians fret over their falling board scores?
Few pediatricians have warm, fuzzy memories about taking their initial board exam.
But many reacted strongly when they read a recent post on Twitter by Bryan Carmody, MD, who noted that the passing rate for first-time test takers had dipped to its lowest level in 5 years – hitting 81% in 2021, down from 91% 3 years earlier.
“It’s literally an awfully written exam,” replied one person who posted. Another asked: “At what point is the exam just not reflective of clinical practice?” And, inevitably, the question of the effect of COVID-19 surfaced: “Is any of this attributable to pulling early career physicians into the pandemic?”
But Dr. Carmody, an associate professor of pediatrics at the University of Eastern Virginia Medical School, Norfolk, isn’t buying that explanation. He researched board scores for internal medicine, general surgery, and family medicine for 2021. All were stable during the same period, he said, leading him to dismiss the idea that the pandemic drove the decline. “It’s not really clear to me why other specialties wouldn’t have seen similar drops,” Dr. Carmody said.
The slip has caught the attention of the American Board of Pediatrics, according to Judy Schaechter, MD, MBA, who was chair of the department of pediatrics at the University of Miami before taking her post as president and CEO of the American Board of Pediatrics in 2021.
“So, our first question was, was this within the range of what one might expect?” Dr. Schaechter said. “Were there other factors that might have come into play?”
The board performs an extensive analysis every year before releasing scores, and it didn’t uncover any changes in the difficulty or content of the test in 2021, nor did the score that was needed to pass increase. Dr. Schaechter pointed out that the passing rate that year was not unprecedented – in 2016, it also dipped to 81%.
Dr. Schaechter said COVID-19 might have affected test takers. “Remember, pediatrics was different from any other specialty during the pandemic,” she said. The census in pediatric wards around the country dropped dramatically in the first two winters of the pandemic, leaving residents with less hands-on experience with patients and mentorship from attendings – both of which can help test-takers pass the exam.
Eyal Ben-Isaac, MD, an associate professor of the department of pediatrics at the Keck School of Medicine at the University of Southern California, Los Angeles, said residents likely suffered during the pandemic, when noon lectures and grand rounds became virtual events.
“I’m sure that clearly affected a person’s ability to sit and listen and really learn the material, as opposed to either doing it hands on or learning the material from a faculty member face to face,” Dr. Ben-Isaac said.
But how much do the didactic experiences of residency programs contribute to residents’ readiness to take the boards? Thomas Welch, MD, professor and chair emeritus of the department of pediatrics at SUNY Upstate Medical University, Syracuse, credits his own success in advancing through college, medical school, pediatric residency, and nephrology fellowship to his skill as a test taker.
He confirmed his suspicions by conducting a study that evaluated correlations between residents’ performance on the United States Medical Licensing Exam (USMLE) taken during medical school and their board scores after completing residency.
Dr. Welch said he wasn’t surprised to find that “the best predictor of one’s passing the pediatric boards was not the training program in which one worked. It was their performance on Step 2 [taken during the fourth year of medical school] of the USMLE.”
Although Dr. Ben-Isaac felt that changes in residency training opportunities might have partially explained the drop in passing rates, he agreed that other factors contribute to success on boards. As director of the pediatric residency program at Children’s Hospital of Los Angeles from 1994 to 2019, one of his first goals was to increase the pass rate of graduates. He developed a board review course for residents, revising it over time on the basis of resident feedback and adding individual coaching for residents who wanted more help.
“Without a question, it raised our board pass rate to being one of the highest in the country,” he said.
Dr. Welch said that while “being up all night with a sick child teaches you a lot about medicine and certainly makes you a better doctor, it doesn’t do anything to improve your board scores.”
None of the pediatricians was too worried about a 1-year drop in scores, and the consensus was that supporting residents with review courses and coaching on how to take multiple choice tests would raise passing rates.
“There are definitely people who are amazing clinicians who did not pass the boards on their first attempt,” Dr. Ben-Isaac said.
But Dr. Schaechter defended the importance of the examination. “Our first obligation is really to the public,” she said. The ABP’s role is to ensure that pediatricians “provide the care that parents want their kids to have.”
As Dr. Welch put it, “Would I trust someone who didn’t pass the board exam to take care of my own kid? Probably not.”

Findings question value of pessary for pelvic organ prolapse
The standard nonsurgical treatment for pelvic organ prolapse does not appear to work as well as surgery to correct the problem, Dutch researchers have found.
Pelvic organ prolapse is an uncomfortable condition, causing a troublesome vaginal bulge, often accompanied by urinary, bowel, or sexual dysfunction. Between 3% and 6% of women develop symptomatic prolapse, with the highest incidence in women aged 60-69 years – a fast-growing demographic.
Although many women choose surgical treatment, the American College of Obstetricians and Gynecologists recommends that women be offered a vaginal pessary as a noninvasive alternative, despite inconsistent data from observational studies on their effectiveness.
Lisa van der Vaart, MD, a doctoral student in ob.gyn. at the University of Amsterdam and the lead author of the new study, published in JAMA, said that differences in outcome measures, small sample size, and lack of long-term follow-up have bedeviled previous comparisons of the two techniques.
“We thought it was very important to perform a randomized control trial on this subject to improve counseling to women who suffer from symptomatic pelvic organ prolapse,” Dr. van der Vaart said.
She and her colleagues conducted a noninferiority randomized clinical trial that recruited 1,605 women with stage II or higher prolapse who were referred to specialty care at 21 hospitals in the Netherlands between 2015 and 2019. Of the 440 women who agreed to participate in the trial, 218 received a pessary, a device inserted into the vagina that provides support to tissues displaced by prolapse, and 222 underwent surgery.
The primary outcome was subjective improvement using a standardized questionnaire at 24 months; women were asked to rank their symptoms on a seven-point scale, and subjective improvement was defined as a response of much better or very much better.
“We saw a substantial amount of improvement in both groups,” Dr. van der Vaart said in an interview.
After 24 months of follow-up, outcome data were available for 173 women in the pessary group and 162 in the surgery group. For this intention-to treat population, 76.3% in the pessary group and 81.5% in the surgery group reported improvement.
Results were similar for the smaller group of participants who completed the study per protocol, without crossing over to a treatment to which they had not been allocated.
However, neither the intention-to-treat nor per-protocol analysis met the prespecified criteria for noninferiority, suggesting that use of a vaginal pessary is not equivalent to surgery.
The study also found differences in adverse events. Among women randomly assigned to surgery, 9% suffered a postoperative urinary tract infection, and 5.4% underwent additional therapy, such as pessary or repeat operation.
But use of a pessary also had downsides. The most common adverse event was discomfort (42.7%), and by 24 months, 60% of the participants in the pessary group had discontinued use.
Dr. van der Vaart said that she was surprised by the high number of women assigned to the pessary group who later elected to undergo surgery. “Women should be told that their chance of crossing over to a surgical intervention is quite high – more than 50% do eventually end up having surgery.”
Cheryl Iglesia, MD, director of the National Center for Advanced Pelvic Surgery at MedStar Health and professor of obstetrics and gynecology and urology at Georgetown University, both in Washington, was also struck by the high crossover rate. “We’ve had the same pessaries probably for the last 100 years,” she said. “We need to get better.”
Dr. Iglesia welcomed new approaches to making vaginal pessaries that are custom designed for each woman’s unique anatomy using 3D printing and pointed to promising initial clinical trials of disposable pessaries. With the aging of the population and demand for treatment of prolapse increasing, she cited a need for better nonsurgical alternatives: “We have a work-force issue and may not have enough adequately trained urogynecologists to meet the demand for prolapse repairs as our population ages.”
The study was funded by a grant from ZonMW, a Dutch governmental health care organization. Dr. van der Vaart reported grants from ZonMW during the conduct of the study.

Results were similar for the smaller group of participants who completed the study per protocol, without crossing over to a treatment to which they had not been allocated.
However, neither the intention-to-treat nor per-protocol analysis met the prespecified criteria for noninferiority, suggesting that use of a vaginal pessary is not equivalent to surgery.
The study also found differences in adverse events. Among women randomly assigned to surgery, 9% suffered a postoperative urinary tract infection, and 5.4% underwent additional therapy, such as pessary or repeat operation.
But use of a pessary also had downsides. The most common adverse event was discomfort (42.7%), and by 24 months, 60% of the participants in the pessary group had discontinued use.
Dr. van der Vaart said that she was surprised by the high number of women assigned to the pessary group who later elected to undergo surgery. “Women should be told that their chance of crossing over to a surgical intervention is quite high – more than 50% do eventually end up having surgery.”
Cheryl Iglesia, MD, director of the National Center for Advanced Pelvic Surgery at MedStar Health and professor of obstetrics and gynecology and urology at Georgetown University, both in Washington, was also struck by the high crossover rate. “We’ve had the same pessaries probably for the last 100 years,” she said. “We need to get better.”
Dr. Iglesia welcomed new approaches to making vaginal pessaries that are custom designed for each woman’s unique anatomy using 3D printing and pointed to promising initial clinical trials of disposable pessaries. With the aging of the population and demand for treatment of prolapse increasing, she cited a need for better nonsurgical alternatives: “We have a work-force issue and may not have enough adequately trained urogynecologists to meet the demand for prolapse repairs as our population ages.”
The study was funded by a grant from ZonMW, a Dutch governmental health care organization. Dr. van der Vaart reported grants from ZonMW during the conduct of the study.

The standard nonsurgical treatment for pelvic organ prolapse does not appear to work as well as surgery to correct the problem, Dutch researchers have found.
Pelvic organ prolapse is an uncomfortable condition, causing a troublesome vaginal bulge, often accompanied by urinary, bowel, or sexual dysfunction. Between 3% and 6% of women develop symptomatic prolapse, with the highest incidence in women aged 60-69 years – a fast-growing demographic.
Although many women choose surgical treatment, the American College of Obstetricians and Gynecologists recommends that women be offered a vaginal pessary as a noninvasive alternative, despite inconsistent data from observational studies on their effectiveness.
Lisa van der Vaart, MD, a doctoral student in ob.gyn. at the University of Amsterdam and the lead author of the new study, published in JAMA, said that differences in outcome measures, small sample size, and lack of long-term follow-up have bedeviled previous comparisons of the two techniques.
“We thought it was very important to perform a randomized control trial on this subject to improve counseling to women who suffer from symptomatic pelvic organ prolapse,” Dr. van der Vaart said.
She and her colleagues conducted a noninferiority randomized clinical trial that recruited 1,605 women with stage II or higher prolapse who were referred to specialty care at 21 hospitals in the Netherlands between 2015 and 2019. Of the 440 women who agreed to participate in the trial, 218 received a pessary, a device inserted into the vagina that provides support to tissues displaced by prolapse, and 222 underwent surgery.
The primary outcome was subjective improvement using a standardized questionnaire at 24 months; women were asked to rank their symptoms on a seven-point scale, and subjective improvement was defined as a response of much better or very much better.
“We saw a substantial amount of improvement in both groups,” Dr. van der Vaart said in an interview.
