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

The ‘psychological warfare’ of prior authorization
Shikha Jain, MD, felt the urgency of the moment.
It was 10:00 AM. A young patient had stepped into her Chicago cancer clinic. His face was red, and he was struggling to breathe.
The man had primary mediastinal B-cell lymphoma, a rare, aggressive form of non-Hodgkin lymphoma. Many cases involve large, fast‐growing masses that expand into the lungs and compress respiratory pathways, sometimes leaving patients breathless.
Dr. Jain rushed to his side and walked him from the clinic to an ICU bed at the hospital nearby.
“He was so sick,” recalled Dr. Jain, currently a tenured associate professor of medicine in the division of hematology and oncology at the University of Illinois Cancer Center, Chicago. “He needed chemotherapy immediately.”
The standard chemotherapy regimen at the time – R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) – required prior authorization.
Dr. Jain’s patient did not have days to wait, so Dr. Jain requested an expedited approval. The insurance company responded quickly, denying the request for treatment.
That evening, after hours on the phone trying to reverse the denial, Dr. Jain was able to arrange a peer-to-peer conversation with the insurer. She explained her patient’s pressing need for chemotherapy: He would die if he continued to wait.
But Dr. Jain’s argument did not move the reviewer. At that point, she had reached her limit.
“I asked for the gentleman’s full name. I told him he would be responsible for this 30-year-old man’s death, and my next call would be to CNN,” Dr. Jain told this news organization. “And that is how I got my patient’s chemotherapy approved.”
Her patient received the regimen that evening. He later went into remission.
This incident occurred almost a decade ago, but it has stayed with Dr. Jain. She knows that her persistence in that moment meant the difference between her patient’s life and death.
There was the denial for standard-of-care staging and surveillance imaging – dotatate PET/CT – for her patient with neuroendocrine cancer. “The specific insurance company simply doesn’t approve this imaging, despite being around for years,” she said.
There was the patient with metastatic colon cancer who needed third-line therapy. His insurer took more than a month to reverse its denial for a recently approved drug, and in that time, the man’s disease progressed. “He eventually succumbed to the cancer after receiving the drug, but it’s unclear if his life was cut short by the delay in care,” Dr. Jain said.
And there is the maze of insurance company phone calls and transfers. On one call, Dr. Jain recalled being transferred six times before being connected to the right department to discuss approving standard-of-care chemotherapy for a patient. After being denied approval, Dr. Jain was put on hold to speak with a manager, and the call was abruptly disconnected.
“I have wasted so many hours on prior authorization and have seen months and months of patient care delays,” Dr. Jain said. “It’s easy to see why people just give up.”
For Dr. Jain, prior authorization has begun to “feel like psychological warfare,” she said. “To have everything questioned by people who don’t understand the basics of oncology is demoralizing.”
The growing administrative – and emotional – burden of prior authorization is contributing to physician burnout.
According to Medscape’s ‘I Cry but No One Cares’: Physician Burnout & Depression Report 2023, more than half of oncologists reported feeling burned out this year – the highest percentage in 5 years. When asked what factors led to burnout, most doctors surveyed pointed to an overabundance of bureaucratic tasks, and specifically, “insurance companies telling me how to practice medicine and controlling what the patients can and can’t do.”
“Burnout is a real problem in medicine,” said Kelly Anderson, PhD, MPP, assistant professor in the department of clinical pharmacy, University of Colorado at Denver, Aurora. “While there are many factors that contribute to burnout, prior authorization is certainly one.”
In a 2022 survey from the American Medical Association, 88% of respondents reported that the burden associated with prior authorization requirements was “high or extremely high.”
Although insurers argue that prior authorization cuts down on unnecessary and expensive care, physicians in the AMA survey reported that this practice often leads to greater overall use of health care resources, including more emergency department and office visits.
“Insurers are confident that prior authorization is saving money overall, but there’s also no clear evidence of that,” Dr. Anderson noted. “Prior authorization may reduce spending without harming patients in some instances, but in others, it’s adding administrative burden, costs, and may be causing harm to patients.”

There was the denial for standard-of-care staging and surveillance imaging – dotatate PET/CT – for her patient with neuroendocrine cancer. “The specific insurance company simply doesn’t approve this imaging, despite being around for years,” she said.
There was the patient with metastatic colon cancer who needed third-line therapy. His insurer took more than a month to reverse its denial for a recently approved drug, and in that time, the man’s disease progressed. “He eventually succumbed to the cancer after receiving the drug, but it’s unclear if his life was cut short by the delay in care,” Dr. Jain said.
And there is the maze of insurance company phone calls and transfers. On one call, Dr. Jain recalled being transferred six times before being connected to the right department to discuss approving standard-of-care chemotherapy for a patient. After being denied approval, Dr. Jain was put on hold to speak with a manager, and the call was abruptly disconnected.
“I have wasted so many hours on prior authorization and have seen months and months of patient care delays,” Dr. Jain said. “It’s easy to see why people just give up.”
For Dr. Jain, prior authorization has begun to “feel like psychological warfare,” she said. “To have everything questioned by people who don’t understand the basics of oncology is demoralizing.”
The growing administrative – and emotional – burden of prior authorization is contributing to physician burnout.
According to Medscape’s ‘I Cry but No One Cares’: Physician Burnout & Depression Report 2023, more than half of oncologists reported feeling burned out this year – the highest percentage in 5 years. When asked what factors led to burnout, most doctors surveyed pointed to an overabundance of bureaucratic tasks, and specifically, “insurance companies telling me how to practice medicine and controlling what the patients can and can’t do.”
“Burnout is a real problem in medicine,” said Kelly Anderson, PhD, MPP, assistant professor in the department of clinical pharmacy, University of Colorado at Denver, Aurora. “While there are many factors that contribute to burnout, prior authorization is certainly one.”
In a 2022 survey from the American Medical Association, 88% of respondents reported that the burden associated with prior authorization requirements was “high or extremely high.”
Although insurers argue that prior authorization cuts down on unnecessary and expensive care, physicians in the AMA survey reported that this practice often leads to greater overall use of health care resources, including more emergency department and office visits.
“Insurers are confident that prior authorization is saving money overall, but there’s also no clear evidence of that,” Dr. Anderson noted. “Prior authorization may reduce spending without harming patients in some instances, but in others, it’s adding administrative burden, costs, and may be causing harm to patients.”

Parsing the split-decision victory for biologics in COPD
It’s tough to keep up with the proliferation of monoclonal antibodies. Seems every day I’m confronted by a patient who’s using a new drug with a name ending in “mab.” That drug blocks a cellular receptor I haven’t heard of that’s involved in a cascade of interactions I haven’t thought about since medical school. The resulting disruption reduces disease burden, typically at great expense to the medical system, the patient, or both. We’ve truly entered the era of precision medicine. It’s not enough to understand disease; you also must know its heterogeneous expression so that you can prescribe the ‘mab that targets the biology responsible for variants in behavior. All diseases are, in fact, syndromes. This isn’t a bad thing, but it’s a challenge.
A series of ‘mabs have been approved for treating type 2 high (TH2) or eosinophilic asthma. We refer to this group of ‘mabs generically as biologics. The group includes omalizumab, mepolizumab, dupilumab, benralizumab, reslizumab, and tezepelumab. While mechanism of action varies slightly across drugs, the biologics all target a specific arm of the immune system. Efficacy is linearly related to serum eosinophil count and there’s little clinically or pharmacologically to distinguish one from another. Of course, no head-to-head comparisons of efficacy are available and there’s no financial incentive for them to be performed.
Latest research
A new randomized controlled trial (RCT) of dupilumab for chronic obstructive pulmonary disease (COPD) adds to the aforementioned biologic knowledge base. Turns out it works as long as the patients are carefully selected. Researchers enrolled GOLD D (or E depending on which iteration of the GOLD Statement you use) patients on triple inhaler therapy (inhaled corticosteroids [ICS]/long-acting beta-agonist [LABA]/long-acting muscarinic antagonist [LAMA]) with two moderate exacerbations or one exacerbation requiring hospitalization in the past year. Blood eosinophil counts were > 300 cells/mcL and chronic bronchitis was present clinically. The primary and multiple secondary outcomes were improved with dupilumab.
This is welcome news. I’ve treated countless patients with severe COPD who have repeated exacerbations despite my efforts to prevent them. These patients are on ICS/LABA/LAMA and azithromycin or roflumilast, and occasionally both. While every COPD guideline known to man forbids using chronic oral corticosteroids (OCS), I’ve prescribed them repeatedly because the benefits to keeping a recalcitrant, exacerbating patient out of the hospital seem to outweigh OCS risks. It would be nice to have a better option. Although we were taught that they were immutably distinct in medical school, every first-year pulmonary fellow knows that asthma and COPD share more similarities than differences, so it makes sense that proven asthma therapies would work for some patients with COPD.
However, the dupilumab study must be placed in context. Past studies haven’t been as positive. In 2017, two separate RCTs found that mepolizumab reduced the annual rate of moderate to severe exacerbations (primary outcome) in one trial but not the other. Interpretation gets more complicated when broken down by intention to treat (ITT) vs. modified ITT and when secondary outcomes are considered. Sparing you those details, this trial does not instill confidence, leading the Food and Drug Administration to refuse approval for mepolizumab for COPD. A second RCT of benralizumab for COPD was published in 2019. Much less cognitive load was required to interpret this one; it was negative. FDA approval was not requested.
Looking through the trial designs for the three RCTs of biologics for COPD, I couldn’t find major differences that could explain the discordant results. Sample size and enrollment criteria were similar. As stated, I don’t believe that the biologic data in asthma allow for predicting efficacy in one eosinophilic patient vs. another and I assume the same would be true for COPD. All three trials found that eosinophils were eliminated, so responses were biologically equivalent.
Key takeaways
If trial design and pharmacology don’t account for the disparate outcomes, how do we explain them? More important, how do we translate these trials into clinical practice? I looked for a review or editorial by a scientist-clinician smarter than I so I could steal their ideas and express them as pedantic euphemisms here. I found it curious that I was unable to find one. A recent publication in the American Journal of Respiratory and Critical Care Medicine suggests that the answer lies within the complex lattice of eosinophil subtypes, but I’m unqualified to judge the veracity of this “phenotype within a phenotype” theory.
More trials in COPD are being done. We should have results on tezepelumab, that great savior that may cover noneosinophilic asthma phenotypes, within the next few years. Until then, we’re stuck defying guidelines with the anachronistic use of OCS for the COPD patient who exacerbates through ICS/LABA/LAMA, roflumilast, and azithromycin.

Treating obesity: Will new drugs end the crisis?
This is the second in a three-part series on the obesity crisis. Part one tackles a complicated question – why does the obesity rate keep rising despite our efforts to stop it? – and can be found here. Part three shows how doctors and patients can make treatment better and can be found here.
In the mid-1980s, Louis J. Aronne, MD, strolled into a lab at Rockefeller University in New York where a colleague was breeding mice. “I will never forget what he showed me,” said Dr. Aronne, now the director of obesity research and treatment at Weill Cornell Medicine in New York. “He had a cage with 10 mice, one severely obese and the others normal weight. He took blood from one of the thin mice and gave it to the fat mouse.”
When Dr. Aronne returned 3 days later, that obese mouse had turned thin.
It was proof of something Dr. Aronne already suspected: Obesity had biological causes and wasn’t just a failure of willpower.
Years later, in 1994, that research led to the discovery of leptin, a hormone released from fat cells that’s involved in the regulation of body weight. It was a watershed moment in obesity research.
Since then, Dr. Aronne and others have worked to build the clinical field of obesity medicine, attempting to shift the public and medical view of obesity from a purely behavioral issue to a disease worthy of medical treatment.
All the while, the U.S. obesity rate soared.
Now, another watershed moment: We finally have highly effective obesity drugs. The hype is real, and so are the weight loss results.
“I’ve been saying for 30 years that when we find treatments that really work, people aren’t going to believe the results,” Dr. Aronne said. “It took longer than I expected, but it’s gratifying now to see.”
The big question
The emerging class of obesity medications known as GLP-1 agonists is indeed a game changer. The weight loss drug semaglutide (Ozempic, Wegovy) showed groundbreaking results, and studies suggest a parade of even more impressive drugs is on the way.
Yes, the drugs offer new hope to millions with obesity complications. But to truly turn the tide on our 42% obesity rate, much more work remains to be done, researchers said, including answering a big question:
How do these weight loss drugs work?
“We have new blockbuster drugs, and we don’t even know why they reduce body weight,” said Samuel Klein, MD, professor of medicine and nutritional science at Washington University in St. Louis. “It was by accident that this was discovered.”
Oops, we created a weight loss drug
Developed to treat diabetes, the GLP-1 drugs’ weight loss effects were a surprise. Now that those effects are confirmed, pharmaceutical companies and researchers are racing to figure out how these drugs work.
In the 1960s, scientists discovered the incretin effect – when you eat glucose (sugar), your body makes more insulin than it does if glucose is given intravenously. Glucose passes through the GI tract and the gut releases hormones that stimulate insulin secretion. It’s “essentially a feed-forward signal to your pancreas to tell it, ‘By the way, you need to be ready because there’s a bunch of glucose coming,’ ” said Randy Seeley, MD, director of the Michigan Nutrition Obesity Research Center, funded by the National Institutes of Health.
One of these hormones – or “incretins” – is GLP-1. In experiments, people with type 2 diabetes who were hooked up to GLP-1 saw their blood sugar go down.
“That led to the idea that if we could take this native hormone and make it last longer, we’d have a therapy for type 2 diabetes,” said Dr. Seeley. Thanks to a GLP-1-like compound in the saliva of the Gila monster, that idea became reality in the 2000s.
Along the way, a surprising side finding came to light: In early trials, diabetes patients on these drugs dropped weight.
Both Ozempic and Wegovy – brand names for semaglutide – are once-weekly injections (pill forms to treat obesity are on the way), but the latter is a higher dose.
“That dose results in about 40% of patients in the clinical trials achieving a 20% weight loss. We’ve just had nothing like that in terms of efficacy before,” said Dr. Seeley, who has worked with some of the drug companies (including Novo Nordisk, the maker of Ozempic and Wegovy, and Eli Lilly, maker of Mounjaro) that market the GLP-1s.
By contrast, semaglutide’s once-a-day predecessor liraglutide (Saxenda, made by Novo Nordisk) can lead to about 10% weight loss.
“And one of the ironies is, we don’t really know why,” Dr. Seeley said. “We don’t know why semaglutide is a better molecule for weight loss than liraglutide.”
Initially, scientists believed that the drugs, in addition to telling the pancreas to secrete more insulin, were also signaling the brain that you’re full. “Turns out that’s not really the way it works,” Dr. Seeley said. “GLP-1 made from your gut probably doesn’t get into your brain very much. But you make GLP-1 in your brain as well.”
For weight loss, it’s the brain’s GLP-1 system, not the gut’s, that the drugs are thought to hijack. But exactly which parts of the brain they affect and how is unknown. “That’s something lots of people are working on, including our own lab,” Dr. Seeley said. (Another surprise: The drugs may have potential as an anti-addiction treatment.)
The diabetes medication tirzepatide (Mounjaro), expected to be approved for weight loss as early as this year, is also a weekly injection, but it has a unique feature: It starts a response not just for GLP-1 but also for another incretin called GIP. Turns out, two is better than one: Trial participants on tirzepatide lost up to 22.5% of their body weight.
More of these hybrid drugs are on the way, Dr. Seeley said. In mid-stage clinical trials, the drug retatrutide, which targets three hormones, led to 24% weight loss. “The idea is the more bullets we can load into the gun, the more we can push the biology into a place where it’s easier to lose weight.”
Shifting from prevention to damage control
Less invasive and more scalable than surgery (only 1% of the eligible population gets bariatric surgery), the drugs offer doctors a safe, effective way to treat many patients with obesity. That’s cause for excitement, but concerns remain because they are expensive, costing about $800 to $1,300 per month out of pocket. Many health insurers, including Medicare, do not cover them for weight loss.
“You have this significant advance in obesity treatment, but very few will be able to access it,” said Gary Foster, PhD, adjunct professor of psychology in psychiatry at the University of Pennsylvania, Philadelphia, and chief scientific officer at WW (formerly Weight Watchers).
There is a push, including a proposed bill, to get Medicare to cover obesity medication. But given the expense of the drugs, the health economics do not support that move, according to an editorial in the New England Journal of Medicine. If Medicare were to cover obesity meds, the budget impact would likely be huge, potentially driving up premiums. If other payers followed suit, the impact could be felt across the U.S. health care system.
Other drawbacks include side effects – including nausea, diarrhea, stomach pain, and vomiting – that can be so bad that some patients can’t tolerate them.
And critically, the drugs do not deal with the root cause of the problem, said Robert Lustig, MD, an endocrinologist and pediatrician at the University of California, San Francisco, who has suggested that excess insulin is driving obesity. “No one has the disease that these drugs are treating. No one has GLP-1 deficiency. They’re bypassing the problem. They’re band-aiding the problem.”
Because the drugs work by mimicking starvation – they appear to curb hunger, so you eat less – people on them lose not just fat but also healthy lean mass, Dr. Lustig said.
Concerns about pancreatitis did not really bear out in postmarketing reports. (The drugs are still not recommended in people with pancreatitis or multiple endocrine neoplasia.) But predicting longer-term outcomes can be difficult, noted Dr. Lustig.
Then there are philosophical questions, said James Hill, PhD, director of the Nutrition Obesity Research Center at the University of Alabama at Birmingham.. “If you’re continuing to not exercise and eat not healthy foods and take a medication, is that success? Have we won when people are at a lower weight but not doing a healthy behavior?”
‘We can’t treat our way out of this’
The fact is, ending the obesity epidemic is a tall order, even for drugs as impressive as these.
“We can’t treat our way out of this,” said Jamy Ard, MD, codirector of Wake Forest Baptist Health Weight Management Center in Winston-Salem, N.C. “The treatments we have now are great, and there will be more coming. But we do need to figure out the prevention side of things.”
Dr. Seeley agreed but added that we can’t diet-and-exercise our way out either.
“There’s no switch to be flipped,” Dr. Seeley said. “If you told me we shouldn’t spend all this money on these drugs, we should spend it on prevention – great! What would we do?”
And prevention efforts won’t help the millions already living with health problems from obesity, Dr. Aronne said.
“Getting people to stop smoking prevents lung cancer. But stopping smoking doesn’t treat lung cancer,” Dr. Aronne said. “Once the physical changes occur in the lung that cause a tumor to grow, it’s too late. You have to think of obesity the same way.”
Dr. Seeley pointed out that “fearmongering” around the drugs highlights our lingering bias that obesity is a lifestyle issue that should not be medically treated.
“People say, ‘When you stop taking it, you’re going to gain the weight back,’ ” Dr. Seeley said. “There’s truth to that, but when you stop taking your hypertension medication, your blood pressure goes up. We don’t think of that as a [reason] for why you shouldn’t take your blood pressure medication. But that gets trumpeted into all these conversations about whether people [with obesity] should be treated at all.”
Like obesity, blood pressure was once thought to be a behavioral problem, Dr. Aronne said. But blood pressure meds prevent heart attacks and strokes. And it’s likely obesity meds will do the same.
One 55-year-old patient on the road to kidney failure lost weight on obesity medications, including semaglutide, Dr. Aronne said. Now, 6 years later, his kidney function is back to normal. “Normally, we think of kidney disease as irreversible,” Dr. Aronne said.
In that respect, these drugs should save money in the long run by virtue of heading off those health care costs, said Dr. Seeley, who imagines a future where obesity is not gone but better managed, like high blood pressure is now.
In the end, the drugs are another step toward what Dr. Aronne and many others have always pushed for: Treating obesity as a disease.

But exactly which parts of the brain they affect and how is unknown. “That’s something lots of people are working on, including our own lab,” Dr. Seeley said. (Another surprise: The drugs may have potential as an anti-addiction treatment.)
The diabetes medication tirzepatide (Mounjaro), expected to be approved for weight loss as early as this year, is also a weekly injection, but it has a unique feature: It starts a response not just for GLP-1 but also for another incretin called GIP. Turns out, two is better than one: Trial participants on tirzepatide lost up to 22.5% of their body weight.
More of these hybrid drugs are on the way, Dr. Seeley said. In mid-stage clinical trials, the drug retatrutide, which targets three hormones, led to 24% weight loss. “The idea is the more bullets we can load into the gun, the more we can push the biology into a place where it’s easier to lose weight.”
Shifting from prevention to damage control
Less invasive and more scalable than surgery (only 1% of the eligible population gets bariatric surgery), the drugs offer doctors a safe, effective way to treat many patients with obesity. That’s cause for excitement, but concerns remain because they are expensive, costing about $800 to $1,300 per month out of pocket. Many health insurers, including Medicare, do not cover them for weight loss.
“You have this significant advance in obesity treatment, but very few will be able to access it,” said Gary Foster, PhD, adjunct professor of psychology in psychiatry at the University of Pennsylvania, Philadelphia, and chief scientific officer at WW (formerly Weight Watchers).
There is a push, including a proposed bill, to get Medicare to cover obesity medication. But given the expense of the drugs, the health economics do not support that move, according to an editorial in the New England Journal of Medicine. If Medicare were to cover obesity meds, the budget impact would likely be huge, potentially driving up premiums. If other payers followed suit, the impact could be felt across the U.S. health care system.
Other drawbacks include side effects – including nausea, diarrhea, stomach pain, and vomiting – that can be so bad that some patients can’t tolerate them.
And critically, the drugs do not deal with the root cause of the problem, said Robert Lustig, MD, an endocrinologist and pediatrician at the University of California, San Francisco, who has suggested that excess insulin is driving obesity. “No one has the disease that these drugs are treating. No one has GLP-1 deficiency. They’re bypassing the problem. They’re band-aiding the problem.”
Because the drugs work by mimicking starvation – they appear to curb hunger, so you eat less – people on them lose not just fat but also healthy lean mass, Dr. Lustig said.
Concerns about pancreatitis did not really bear out in postmarketing reports. (The drugs are still not recommended in people with pancreatitis or multiple endocrine neoplasia.) But predicting longer-term outcomes can be difficult, noted Dr. Lustig.
Then there are philosophical questions, said James Hill, PhD, director of the Nutrition Obesity Research Center at the University of Alabama at Birmingham.. “If you’re continuing to not exercise and eat not healthy foods and take a medication, is that success? Have we won when people are at a lower weight but not doing a healthy behavior?”
‘We can’t treat our way out of this’
The fact is, ending the obesity epidemic is a tall order, even for drugs as impressive as these.
“We can’t treat our way out of this,” said Jamy Ard, MD, codirector of Wake Forest Baptist Health Weight Management Center in Winston-Salem, N.C. “The treatments we have now are great, and there will be more coming. But we do need to figure out the prevention side of things.”
Dr. Seeley agreed but added that we can’t diet-and-exercise our way out either.
“There’s no switch to be flipped,” Dr. Seeley said. “If you told me we shouldn’t spend all this money on these drugs, we should spend it on prevention – great! What would we do?”
And prevention efforts won’t help the millions already living with health problems from obesity, Dr. Aronne said.
“Getting people to stop smoking prevents lung cancer. But stopping smoking doesn’t treat lung cancer,” Dr. Aronne said. “Once the physical changes occur in the lung that cause a tumor to grow, it’s too late. You have to think of obesity the same way.”
Dr. Seeley pointed out that “fearmongering” around the drugs highlights our lingering bias that obesity is a lifestyle issue that should not be medically treated.
“People say, ‘When you stop taking it, you’re going to gain the weight back,’ ” Dr. Seeley said. “There’s truth to that, but when you stop taking your hypertension medication, your blood pressure goes up. We don’t think of that as a [reason] for why you shouldn’t take your blood pressure medication. But that gets trumpeted into all these conversations about whether people [with obesity] should be treated at all.”
Like obesity, blood pressure was once thought to be a behavioral problem, Dr. Aronne said. But blood pressure meds prevent heart attacks and strokes. And it’s likely obesity meds will do the same.
One 55-year-old patient on the road to kidney failure lost weight on obesity medications, including semaglutide, Dr. Aronne said. Now, 6 years later, his kidney function is back to normal. “Normally, we think of kidney disease as irreversible,” Dr. Aronne said.
In that respect, these drugs should save money in the long run by virtue of heading off those health care costs, said Dr. Seeley, who imagines a future where obesity is not gone but better managed, like high blood pressure is now.
In the end, the drugs are another step toward what Dr. Aronne and many others have always pushed for: Treating obesity as a disease.

This is the second in a three-part series on the obesity crisis. Part one tackles a complicated question – why does the obesity rate keep rising despite our efforts to stop it? – and can be found here. Part three shows how doctors and patients can make treatment better and can be found here.
In the mid-1980s, Louis J. Aronne, MD, strolled into a lab at Rockefeller University in New York where a colleague was breeding mice. “I will never forget what he showed me,” said Dr. Aronne, now the director of obesity research and treatment at Weill Cornell Medicine in New York. “He had a cage with 10 mice, one severely obese and the others normal weight. He took blood from one of the thin mice and gave it to the fat mouse.”
When Dr. Aronne returned 3 days later, that obese mouse had turned thin.
It was proof of something Dr. Aronne already suspected: Obesity had biological causes and wasn’t just a failure of willpower.
Years later, in 1994, that research led to the discovery of leptin, a hormone released from fat cells that’s involved in the regulation of body weight. It was a watershed moment in obesity research.
Since then, Dr. Aronne and others have worked to build the clinical field of obesity medicine, attempting to shift the public and medical view of obesity from a purely behavioral issue to a disease worthy of medical treatment.
All the while, the U.S. obesity rate soared.
Now, another watershed moment: We finally have highly effective obesity drugs. The hype is real, and so are the weight loss results.
“I’ve been saying for 30 years that when we find treatments that really work, people aren’t going to believe the results,” Dr. Aronne said. “It took longer than I expected, but it’s gratifying now to see.”
The big question
The emerging class of obesity medications known as GLP-1 agonists is indeed a game changer. The weight loss drug semaglutide (Ozempic, Wegovy) showed groundbreaking results, and studies suggest a parade of even more impressive drugs is on the way.
Yes, the drugs offer new hope to millions with obesity complications. But to truly turn the tide on our 42% obesity rate, much more work remains to be done, researchers said, including answering a big question:
How do these weight loss drugs work?
“We have new blockbuster drugs, and we don’t even know why they reduce body weight,” said Samuel Klein, MD, professor of medicine and nutritional science at Washington University in St. Louis. “It was by accident that this was discovered.”
Oops, we created a weight loss drug
Developed to treat diabetes, the GLP-1 drugs’ weight loss effects were a surprise. Now that those effects are confirmed, pharmaceutical companies and researchers are racing to figure out how these drugs work.
In the 1960s, scientists discovered the incretin effect – when you eat glucose (sugar), your body makes more insulin than it does if glucose is given intravenously. Glucose passes through the GI tract and the gut releases hormones that stimulate insulin secretion. It’s “essentially a feed-forward signal to your pancreas to tell it, ‘By the way, you need to be ready because there’s a bunch of glucose coming,’ ” said Randy Seeley, MD, director of the Michigan Nutrition Obesity Research Center, funded by the National Institutes of Health.
One of these hormones – or “incretins” – is GLP-1. In experiments, people with type 2 diabetes who were hooked up to GLP-1 saw their blood sugar go down.
“That led to the idea that if we could take this native hormone and make it last longer, we’d have a therapy for type 2 diabetes,” said Dr. Seeley. Thanks to a GLP-1-like compound in the saliva of the Gila monster, that idea became reality in the 2000s.
Along the way, a surprising side finding came to light: In early trials, diabetes patients on these drugs dropped weight.
Both Ozempic and Wegovy – brand names for semaglutide – are once-weekly injections (pill forms to treat obesity are on the way), but the latter is a higher dose.
“That dose results in about 40% of patients in the clinical trials achieving a 20% weight loss. We’ve just had nothing like that in terms of efficacy before,” said Dr. Seeley, who has worked with some of the drug companies (including Novo Nordisk, the maker of Ozempic and Wegovy, and Eli Lilly, maker of Mounjaro) that market the GLP-1s.
By contrast, semaglutide’s once-a-day predecessor liraglutide (Saxenda, made by Novo Nordisk) can lead to about 10% weight loss.
“And one of the ironies is, we don’t really know why,” Dr. Seeley said. “We don’t know why semaglutide is a better molecule for weight loss than liraglutide.”
Initially, scientists believed that the drugs, in addition to telling the pancreas to secrete more insulin, were also signaling the brain that you’re full. “Turns out that’s not really the way it works,” Dr. Seeley said. “GLP-1 made from your gut probably doesn’t get into your brain very much. But you make GLP-1 in your brain as well.”
For weight loss, it’s the brain’s GLP-1 system, not the gut’s, that the drugs are thought to hijack. But exactly which parts of the brain they affect and how is unknown. “That’s something lots of people are working on, including our own lab,” Dr. Seeley said. (Another surprise: The drugs may have potential as an anti-addiction treatment.)

PCPs key to heart failure care after discharge
Madeline Sterling, MD, knew something was wrong when she heard her patient’s voice on the phone. The patient was breathing too fast and sounded fatigued. Like many people with heart failure, this patient had several comorbidities: diabetes, high blood pressure, and cancer, which was in remission.
The patient had been in and out of the hospital several times and was afraid of going back, but Dr. Sterling, a primary care physician, advised her that it was the safe thing to do.
During the woman’s stay, the inpatient cardiology team called Dr. Sterling to provide status updates and ask for input. When the patient was discharged, Dr. Sterling received information on what medicines had been changed and scheduled follow-up care within 10 days. Dr. Sterling, who’d cared for the woman for many years, called her family, her home health aide, and another caregiver to discuss the plan.
“When you know these patients really well, it’s helpful,” Dr. Sterling, a professor of medicine at Weill Cornell Medicine, New York, said. Primary care clinicians have “an appreciation for how all these conditions fit together, how the medicines fit together, and how to put that patient’s priorities at the front of the equation.”
Research has shown that follow-up care within 7-10 days after discharge, especially for patients with heart failure, can prevent hospital readmissions. Patients’ health can change rapidly following discharge: They may start retaining fluid or may not know how to maintain a low-sodium diet, or they might have trouble obtaining medication. Primary care clinicians spot these early warning signs in follow-up visits.
Heart failure affects more than 6 million adults in the United States, according to the Centers for Disease Control and Prevention. The condition is a common cause of hospital readmissions within 30 days of discharge, according to research published by the American Heart Association.
Patients with heart failure are particularly challenging to care for because of comorbidities.
“They’re a very, very sick group of patients that are very difficult to manage,” said Noah Moss, MD, an advanced heart failure and transplant cardiologist at Mount Sinai Hospital, New York.
But patients do not always receive the follow-up care they need, some studies have found.
Right drugs at the right time
Kelly Axsom, MD, a cardiologist at the Columbia University Medical Center, New York, and director of the centralized heart failure management program at the New York–Presbyterian Hospital System, called the primary care clinician the “captain of the ship,” ensuring that medications are reconciled and providing education about what to eat after discharge.
“It’s actually pretty complicated to go from being in the hospital to being at home,” Dr. Axsom said. “There are often many medication changes, there are lots of instructions that are told to you as a patient that are hard to remember.”
A patient’s weight might fluctuate in the days following discharge because the dose of diuretics might be too low or too high and need to be adjusted, according to Ishani Ganguli, MD, MPH, an assistant professor of medicine and a general internist in the Division of General Internal Medicine and Primary Care at Harvard Medical School and Brigham and Women’s Hospital, Boston.
K. Melissa Hayes, DNP, ANP-BC, CHFN, an assistant professor in the adult gerontology primary care program at the Vanderbilt University School of Nursing, Nashville, Tenn., recalled one patient who was given a months’ worth of medications following his discharge from the hospital.
“He was given expensive medications he couldn’t afford and not any refills or how to get those medications,” Dr. Hayes said.
Sometimes patients have no way to get to the pharmacy, or their pharmacy doesn’t have the medication they need, or their insurance doesn’t cover the drugs.
“The average patient is on at least six medications for heart failure, maybe even seven, and then that’s not including all their other medications,” Dr. Hayes said. “That can be a lot for people to keep up with.”
Dr. Hayes talks to her patients with heart failure about what drugs they have been prescribed and what medications they require more of, and she deprescribes any that are duplicative.
Helping patients understand why they are taking each drug encourages them to stick to the regimen. Diuretics, for example, can lead to frequent urination. If patients are unable to take regular bathroom breaks, they may be tempted to stop using the medication – a potentially catastrophic mistake.
“Often I have patients say, ‘Nobody ever explained it to me that way,’ ” Dr. Hayes said. “Someone can have a PhD but not understand their medications.”
Clinicians also can alert patients to commonly used medications that can worsen heart failure, such as diabetes drugs and over-the-counter medications such as ibuprofen.
Patients should be prescribed a combination of four recommended medications. But several studies have found that clinicians often fail to achieve the target doses for those medications. The use of guideline-directed medications reduces mortality and hospitalization rates, according to multiple clinical trials.
Eyes and ears on the patient
Once home, patients must stick to the right diet, weigh themselves every day, and monitor their blood pressure. But changing behaviors can be a struggle.
“Being seen quickly within a couple of days of discharge, you can catch things,” said Dr. Hayes, who has edited a book on managing patients with heart failure in primary care.
“It’s an opportunity to see how they’re doing at home, make sure they have their medications, make sure there’s been no misunderstanding or miscommunication about what they’re supposed to be doing at home,” says Marc Itskowitz, MD, a primary care physician affiliated with Allegheny General Hospital, Pittsburgh.
Ideally, a record that readily integrates information from wearables – such as blood pressure and weight – would make it easier to spot abnormalities, Dr. Itskowtiz said. “I think we’re still in the infancy of the electronic health record,” he said.
Ensuring that follow-up visits are as accessible as possible for patients is also important. Telehealth makes it easier for patients after they return home from the hospital, Dr. Itskowitz said.
More infrastructure
Another challenge of providing follow-up care for patients with heart failure is completing all the tasks a clinician must do within a 20-minute visit: an examination; education on the condition and medications; counseling on diet and exercise; coordination of medical equipment, such as a blood pressure cuff for home use; and making appointments with specialists.
“In the current system, additional support for primary care is needed so we can do all this,” Dr. Sterling said.
Staff at primary care clinics should be trained to answer calls from patients when they experience changes in their weight or are worried about other potential problems. “A lot of primary care practices are bare bones,” Dr. Hayes said, meaning they might not have the staff to field those calls. Educating patients as to when they should call their physician, especially after experiencing worsening symptoms, is also important.
Dr. Hayes suggests setting aside time in the schedule each week to see patients who have been recently discharged from the hospital. In the Cardiology and Vascular Clinic at Nashville General Hospital, Tenn., where she spends half a day each week, Dr. Hayes requests 30 minutes to see patients who have recently been discharged from hospital.
Even when the process goes smoothly, some patients will return to the hospital because of the progressive nature of heart failure, according to Dr. Hayes. Improving care following their hospitalization can keep these people from rapidly declining.
“Most patients with heart failure want to be taking care of the grandchildren or be able to enjoy family dinners together,” Dr. Axsom said. “I think anything we can do to help improve their quality of life is really important.”
Take-home
- See heart failure patients early after their discharge from hospital, ideally within 7-10 days.
- Make sure patients have access to the right medications at the right dosages and that they know why they’re taking them.
- Educate patients about the diet they should be following.
- Have a system to monitor patients’ symptoms and let them know when they should call.

“It’s actually pretty complicated to go from being in the hospital to being at home,” Dr. Axsom said. “There are often many medication changes, there are lots of instructions that are told to you as a patient that are hard to remember.”
A patient’s weight might fluctuate in the days following discharge because the dose of diuretics might be too low or too high and need to be adjusted, according to Ishani Ganguli, MD, MPH, an assistant professor of medicine and a general internist in the Division of General Internal Medicine and Primary Care at Harvard Medical School and Brigham and Women’s Hospital, Boston.
K. Melissa Hayes, DNP, ANP-BC, CHFN, an assistant professor in the adult gerontology primary care program at the Vanderbilt University School of Nursing, Nashville, Tenn., recalled one patient who was given a months’ worth of medications following his discharge from the hospital.
“He was given expensive medications he couldn’t afford and not any refills or how to get those medications,” Dr. Hayes said.
Sometimes patients have no way to get to the pharmacy, or their pharmacy doesn’t have the medication they need, or their insurance doesn’t cover the drugs.
“The average patient is on at least six medications for heart failure, maybe even seven, and then that’s not including all their other medications,” Dr. Hayes said. “That can be a lot for people to keep up with.”
Dr. Hayes talks to her patients with heart failure about what drugs they have been prescribed and what medications they require more of, and she deprescribes any that are duplicative.
Helping patients understand why they are taking each drug encourages them to stick to the regimen. Diuretics, for example, can lead to frequent urination. If patients are unable to take regular bathroom breaks, they may be tempted to stop using the medication – a potentially catastrophic mistake.
“Often I have patients say, ‘Nobody ever explained it to me that way,’ ” Dr. Hayes said. “Someone can have a PhD but not understand their medications.”
Clinicians also can alert patients to commonly used medications that can worsen heart failure, such as diabetes drugs and over-the-counter medications such as ibuprofen.
Patients should be prescribed a combination of four recommended medications. But several studies have found that clinicians often fail to achieve the target doses for those medications. The use of guideline-directed medications reduces mortality and hospitalization rates, according to multiple clinical trials.
Eyes and ears on the patient
Once home, patients must stick to the right diet, weigh themselves every day, and monitor their blood pressure. But changing behaviors can be a struggle.
“Being seen quickly within a couple of days of discharge, you can catch things,” said Dr. Hayes, who has edited a book on managing patients with heart failure in primary care.
“It’s an opportunity to see how they’re doing at home, make sure they have their medications, make sure there’s been no misunderstanding or miscommunication about what they’re supposed to be doing at home,” says Marc Itskowitz, MD, a primary care physician affiliated with Allegheny General Hospital, Pittsburgh.
Ideally, a record that readily integrates information from wearables – such as blood pressure and weight – would make it easier to spot abnormalities, Dr. Itskowtiz said. “I think we’re still in the infancy of the electronic health record,” he said.
Ensuring that follow-up visits are as accessible as possible for patients is also important. Telehealth makes it easier for patients after they return home from the hospital, Dr. Itskowitz said.
More infrastructure
Another challenge of providing follow-up care for patients with heart failure is completing all the tasks a clinician must do within a 20-minute visit: an examination; education on the condition and medications; counseling on diet and exercise; coordination of medical equipment, such as a blood pressure cuff for home use; and making appointments with specialists.
“In the current system, additional support for primary care is needed so we can do all this,” Dr. Sterling said.
Staff at primary care clinics should be trained to answer calls from patients when they experience changes in their weight or are worried about other potential problems. “A lot of primary care practices are bare bones,” Dr. Hayes said, meaning they might not have the staff to field those calls. Educating patients as to when they should call their physician, especially after experiencing worsening symptoms, is also important.
Dr. Hayes suggests setting aside time in the schedule each week to see patients who have been recently discharged from the hospital. In the Cardiology and Vascular Clinic at Nashville General Hospital, Tenn., where she spends half a day each week, Dr. Hayes requests 30 minutes to see patients who have recently been discharged from hospital.
Even when the process goes smoothly, some patients will return to the hospital because of the progressive nature of heart failure, according to Dr. Hayes. Improving care following their hospitalization can keep these people from rapidly declining.
“Most patients with heart failure want to be taking care of the grandchildren or be able to enjoy family dinners together,” Dr. Axsom said. “I think anything we can do to help improve their quality of life is really important.”
Take-home
- See heart failure patients early after their discharge from hospital, ideally within 7-10 days.
- Make sure patients have access to the right medications at the right dosages and that they know why they’re taking them.
- Educate patients about the diet they should be following.
- Have a system to monitor patients’ symptoms and let them know when they should call.

Geriatric care principles should apply to ICUs as well
Baseball legend Leroy “Satchel” Paige famously said that “age is a question of mind over matter: If you don’t mind, it doesn’t matter.”
But even the strongest and most supple minds can’t avoid the effects of advanced age and accompanying physical frailty, and for community-dwelling elderly with pulmonary diseases frailty is a predictor of both hospitalization and death, investigators have found.
For example, among 1,188 community-dwelling older adults enrolled in the Toledo (Spain) Study for Healthy Aging, declining pulmonary function measured by forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) was associated with increased risk for frailty and hospitalization, and a more than twofold greater risk for death in participants both with and without respiratory diseases. These findings were reported by Walter Sepulveda-Loyola, PT, MSC, PhD, from the Faculty of Health and Social Sciences at Universidad de Las Americas in Santiago, Chile, and colleagues in the journal Heart & Lung.
Similarly, results of a meta-analysis performed by investigators at Jiangsu (China) University showed that among 13,203 patients with chronic obstructive pulmonary disease (COPD), frailty was associated with a more than 2.6-fold relative increase in risk for death from any cause, and “prefrailty,” an intermediate state between frailty and “robustness,” was associated with a 48% relative increase in all-cause mortality. Frailty was also associated with a 2.2-fold risk for COPD exacerbations of any severity, the authors reported in JAMDA: The Journal of Post-Acute and Long-Term Care Medicine.
The good (old) USA
In June 2023 the U.S. Census Bureau announced that the median age of the U.S. population is now 38.9 years, and according to a 2016 Census Bureau report funded by the National Institutes of Health, “America’s 65-and-over population is projected to nearly double over the next three decades, from 48 million to 88 million by 2050.”
With the graying of the U.S. population the burden on pulmonary and critical care experts will almost inevitably increase, as evidenced by research from Julien Cobert, MD, from the University of California, San Francisco, and colleagues.
The investigators looked at trends over time in older adults admitted to ICUs from 1988 through 2015 using data from the Health and Retirement Study (HRS), a nationally representative, longitudinal study of older adults. They found that rates of preexisting frailty, disability, and multimorbidity increased over the study period.
“Our findings suggest a growing prevalence of geriatric conditions among older adults admitted to the ICU, suggesting a pressing need to integrate geriatric principles into critical care medicine. Further research could examine if early interventions emphasizing physical, cognitive, mental health, delirium prevention, advance care planning, and rehabilitation individualized to critically ill elderly patients with preexisting geriatric conditions could improve ICU outcomes and post-ICU recovery,” they wrote in a study published in the journal CHEST.
In an editorial accompanying the study by Dr. Cobert and colleagues, Nathan E. Brummel, MD, from The Ohio State University College of Medicine and Davis Heart and Lung Research Institute in Columbus, said “the finding that nearly 30% of overall HRS participants were admitted to the ICU provides novel data about the extent to which older Americans are affected by critical illness. Because the number of older Americans is projected to continue to increase for the next 30 years or more, these data make clear the ongoing importance of aging-focused research and clinical care.”
Dr. Brummel also noted that older adults who are admitted to the ICU today are at greater risk for poor outcomes than those admitted in prior years, as evidenced by the increased prevalence of disability, frailty, and multimorbidity.
“Moreover, because the average age of those admitted to the ICU only changed by 1 year during the study, these data show that increases in vulnerability are not simply due to chronological age, and they suggest that to identify those with greater baseline vulnerability, screening for geriatric syndromes at ICU admission may be warranted,” he wrote.
Geriatric principles in the ICU
“I think what’s most important is that we think about patients from a geriatric principles standpoint, not just when they’re admitted to the hospital but especially when they’re admitted to the ICU,” Dr. Cobert said in an interview.
“The first step is ensuring that we’re asking questions about their underlying comorbidities, especially around frailty, hearing, vision loss, falls, multimorbidities, polypharmacy – things that are primarily done on the outpatient side in geriatric clinics, but things that we should probably be a little bit more cognizant of, given that we’re starting to see higher rates of patients coming in with these issues,” he said.
Critical care specialists need to take a more holistic approach and try to understand as best they can each patients’ goals and then determine whether the ICU staff are acting in concordance with those goals, he emphasized.
For example, ICU clinicians should try to understand whether patients were losing function or having mobility difficulties before hospital and ICU admission, and what they hope to retain when or if they are discharged. ICU staff can then try as much as reasonably possible to minimize interventions that could contribute to impairment after discharge.
Frailty and COPD in the ICU
There are special considerations for frail elderly with obstructive airway disease, Dr. Cobert noted.
Patients with advanced COPD, for example, are likely to be on home oxygen.
“Home oxygen is a big deal,” he said. “It can definitely help with functioning and there’s potentially a mortality benefit in certain populations. But that said, it’s a flammable object that they have to carry around and lug with them all the time. It contributes to falls, it’s tethering, it’s life-limiting in many ways.”
In addition, many patients with COPD have multiple re-hospitalizations, and for clinicians the challenge is “understanding what their goals are, what their motivations are, especially when they live with dyspnea, with advanced lung disease. Is intubation within their goals of care? Has their functional status been declining over time? Are there things that we can optimize holistically and globally as their COPD advances over time?”
Another important component of critical care for the frail elderly is consideration of patients’ palliative care needs and what their symptoms and symptom burdens were like prior to hospitalizations.
“The ICU experience and the critical illness experience may serve as an inflexion point – more likely a downward inflection point – whereby their needs increase, their symptoms can worsen, and their health, especially their global health, worsens. Their preexisting geriatric conditions might be a moving target after another hit and another traumatic stressor like the ICU setting,” Dr. Cobert said.
The study by Dr. Cobert and colleagues was supported by the National Institute on Aging. Dr. Cobert had no reported conflicts of interest.

Long COVID ‘brain fog’ confounds doctors, but new research offers hope
Kate Whitley was petrified of COVID-19 from the beginning of the pandemic because she has Hashimoto disease, an autoimmune disorder that she knew put her at high risk for complications.
She was right to be worried. Two months after contracting the infection in September 2022, the 42-year-old Nashville resident was diagnosed with long COVID. For Ms. Whitley, the resulting brain fog has been the most challenging factor. She is the owner of a successful paper goods store, and she can’t remember basic aspects of her job. She can’t tolerate loud noises and gets so distracted that she has trouble remembering what she was doing.
Ms. Whitley doesn’t like the term “brain fog” because it doesn’t begin to describe the dramatic disruption to her life over the past 7 months.
Brain fog is among the most common symptoms of long COVID, and also one of the most poorly understood. A reported 46% of those diagnosed with long COVID complain of brain fog or a loss of memory. Many clinicians agree that the term is vague and often doesn’t truly represent the condition. That, in turn, makes it harder for doctors to diagnose and treat it. There are no standard tests for it, nor are there guidelines for symptom management or treatment.
“There’s a lot of imprecision in the term because it might mean different things to different patients,” said James C. Jackson, PsyD, a neuropsychiatrist at Vanderbilt University, Nashville, Tenn., and author of a new book, “Clearing the Fog: From Surviving to Thriving With Long COVID – A Practical Guide.”
Dr. Jackson, who began treating Ms. Whitley in February 2023, said that it makes more sense to call brain fog a brain impairment or an acquired brain injury (ABI) because it doesn’t occur gradually. COVID damages the brain and causes injury. For those with long COVID who were previously in the intensive care unit and may have undergone ventilation, hypoxic brain injury may result from the lack of oxygen to the brain.
Even among those with milder cases of acute COVID, there’s some evidence that persistent neuroinflammation in the brain caused by an activated immune system may also cause damage.
In both cases, the results can be debilitating. Ms. Whitley also has dysautonomia – a disorder of the autonomic nervous system that can cause dizziness, sweating, and headaches along with fatigue and heart palpitations.
She said that she’s so forgetful that when she sees people socially, she’s nervous of what she’ll say. “I feel like I’m constantly sticking my foot in my mouth because I can’t remember details of other people’s lives,” she said.
Although brain disorders such as Alzheimer’s disease and other forms of dementia are marked by a slow decline, ABI occurs more suddenly and may include a loss of executive function and attention.
“With a brain injury, you’re doing fine, and then some event happens (in this case COVID), and immediately after that, your cognitive function is different,” said Dr. Jackson.
Additionally, ABI is an actual diagnosis, whereas brain fog is not.
“With a brain injury, there’s a treatment pathway for cognitive rehabilitation,” said Dr. Jackson.
Treatments may include speech, cognitive, and occupational therapy as well as meeting with a neuropsychiatrist for treatment of the mental and behavioral disorders that may result. Dr. Jackson said that while many patients aren’t functioning cognitively or physically at 100%, they can make enough strides that they don’t have to give up things such as driving and, in some cases, their jobs.
Other experts agree that long COVID may damage the brain. An April 2022 study published in the journal Nature found strong evidence that SARS-CoV-2 infection may cause brain-related abnormalities, for example, a reduction in gray matter in certain parts of the brain, including the prefrontal cortex, hypothalamus, and amygdala.
Additionally, white matter, which is found deeper in the brain and is responsible for the exchange of information between different parts of the brain, may also be at risk of damage as a result of the virus, according to a November 2022 study published in the journal SN Comprehensive Clinical Medicine.
Calling it a “fog” makes it easier for clinicians and the general public to dismiss its severity, said Tyler Reed Bell, PhD, a researcher who specializes in viruses that cause brain injury. He is a fellow in the department of psychiatry at the University of California, San Diego. Brain fog can make driving and returning to work especially dangerous. Because of difficulty focusing, patients are much more likely to make mistakes that cause accidents.
“The COVID virus is very invasive to the brain,” Dr. Bell said.
Others contend this may be a rush to judgment. Karla L. Thompson, PhD, lead neuropsychologist at the University of North Carolina at Chapel Hill’s COVID Recovery Clinic, agrees that in more serious cases of COVID that cause a lack of oxygen to the brain, it’s reasonable to call it a brain injury. But brain fog can also be associated with other long COVID symptoms, not just damage to the brain.
Chronic fatigue and poor sleep are both commonly reported symptoms of long COVID that negatively affect brain function, she said. Sleep disturbances, cardiac problems, dysautonomia, and emotional distress could also affect the way the brain functions post COVID. Finding the right treatment requires identifying all the factors contributing to cognitive impairment.
Part of the problem in treating long COVID brain fog is that diagnostic technology is not sensitive enough to detect inflammation that could be causing damage.
Grace McComsey, MD, who leads the long COVID RECOVER study at University Hospitals Health System in Cleveland, said her team is working on identifying biomarkers that could detect brain inflammation in a way similar to the manner researchers have identified biomarkers to help diagnose chronic fatigue syndrome. Additionally, a new study published last month in JAMA for the first time clearly defined 12 symptoms of long COVID, and brain fog was listed among them. All of this contributes to the development of clear diagnostic criteria.
“It will make a big difference once we have some consistency among clinicians in diagnosing the condition,” said Dr. McComsey.
Ms. Whitley is thankful for the treatment that she’s received thus far. She’s seeing a cognitive rehabilitation therapist, who assesses her memory, cognition, and attention span and gives her tools to break up simple tasks, such as driving, so that they don’t feel overwhelming. She’s back behind the wheel and back to work.
But perhaps most importantly, Ms. Whitley joined a support group, led by Dr. Jackson, that includes other people experiencing the same symptoms she is. When she was at her darkest, they understood.
“Talking to other survivors has been the only solace in all this,” Ms. Whitley said. “Together, we grieve all that’s been lost.”

Other experts agree that long COVID may damage the brain. An April 2022 study published in the journal Nature found strong evidence that SARS-CoV-2 infection may cause brain-related abnormalities, for example, a reduction in gray matter in certain parts of the brain, including the prefrontal cortex, hypothalamus, and amygdala.
Additionally, white matter, which is found deeper in the brain and is responsible for the exchange of information between different parts of the brain, may also be at risk of damage as a result of the virus, according to a November 2022 study published in the journal SN Comprehensive Clinical Medicine.
Calling it a “fog” makes it easier for clinicians and the general public to dismiss its severity, said Tyler Reed Bell, PhD, a researcher who specializes in viruses that cause brain injury. He is a fellow in the department of psychiatry at the University of California, San Diego. Brain fog can make driving and returning to work especially dangerous. Because of difficulty focusing, patients are much more likely to make mistakes that cause accidents.
“The COVID virus is very invasive to the brain,” Dr. Bell said.
Others contend this may be a rush to judgment. Karla L. Thompson, PhD, lead neuropsychologist at the University of North Carolina at Chapel Hill’s COVID Recovery Clinic, agrees that in more serious cases of COVID that cause a lack of oxygen to the brain, it’s reasonable to call it a brain injury. But brain fog can also be associated with other long COVID symptoms, not just damage to the brain.
Chronic fatigue and poor sleep are both commonly reported symptoms of long COVID that negatively affect brain function, she said. Sleep disturbances, cardiac problems, dysautonomia, and emotional distress could also affect the way the brain functions post COVID. Finding the right treatment requires identifying all the factors contributing to cognitive impairment.
Part of the problem in treating long COVID brain fog is that diagnostic technology is not sensitive enough to detect inflammation that could be causing damage.
Grace McComsey, MD, who leads the long COVID RECOVER study at University Hospitals Health System in Cleveland, said her team is working on identifying biomarkers that could detect brain inflammation in a way similar to the manner researchers have identified biomarkers to help diagnose chronic fatigue syndrome. Additionally, a new study published last month in JAMA for the first time clearly defined 12 symptoms of long COVID, and brain fog was listed among them. All of this contributes to the development of clear diagnostic criteria.
“It will make a big difference once we have some consistency among clinicians in diagnosing the condition,” said Dr. McComsey.
Ms. Whitley is thankful for the treatment that she’s received thus far. She’s seeing a cognitive rehabilitation therapist, who assesses her memory, cognition, and attention span and gives her tools to break up simple tasks, such as driving, so that they don’t feel overwhelming. She’s back behind the wheel and back to work.
But perhaps most importantly, Ms. Whitley joined a support group, led by Dr. Jackson, that includes other people experiencing the same symptoms she is. When she was at her darkest, they understood.
“Talking to other survivors has been the only solace in all this,” Ms. Whitley said. “Together, we grieve all that’s been lost.”

Kate Whitley was petrified of COVID-19 from the beginning of the pandemic because she has Hashimoto disease, an autoimmune disorder that she knew put her at high risk for complications.
She was right to be worried. Two months after contracting the infection in September 2022, the 42-year-old Nashville resident was diagnosed with long COVID. For Ms. Whitley, the resulting brain fog has been the most challenging factor. She is the owner of a successful paper goods store, and she can’t remember basic aspects of her job. She can’t tolerate loud noises and gets so distracted that she has trouble remembering what she was doing.
Ms. Whitley doesn’t like the term “brain fog” because it doesn’t begin to describe the dramatic disruption to her life over the past 7 months.
Brain fog is among the most common symptoms of long COVID, and also one of the most poorly understood. A reported 46% of those diagnosed with long COVID complain of brain fog or a loss of memory. Many clinicians agree that the term is vague and often doesn’t truly represent the condition. That, in turn, makes it harder for doctors to diagnose and treat it. There are no standard tests for it, nor are there guidelines for symptom management or treatment.
“There’s a lot of imprecision in the term because it might mean different things to different patients,” said James C. Jackson, PsyD, a neuropsychiatrist at Vanderbilt University, Nashville, Tenn., and author of a new book, “Clearing the Fog: From Surviving to Thriving With Long COVID – A Practical Guide.”
Dr. Jackson, who began treating Ms. Whitley in February 2023, said that it makes more sense to call brain fog a brain impairment or an acquired brain injury (ABI) because it doesn’t occur gradually. COVID damages the brain and causes injury. For those with long COVID who were previously in the intensive care unit and may have undergone ventilation, hypoxic brain injury may result from the lack of oxygen to the brain.
Even among those with milder cases of acute COVID, there’s some evidence that persistent neuroinflammation in the brain caused by an activated immune system may also cause damage.
In both cases, the results can be debilitating. Ms. Whitley also has dysautonomia – a disorder of the autonomic nervous system that can cause dizziness, sweating, and headaches along with fatigue and heart palpitations.
She said that she’s so forgetful that when she sees people socially, she’s nervous of what she’ll say. “I feel like I’m constantly sticking my foot in my mouth because I can’t remember details of other people’s lives,” she said.
Although brain disorders such as Alzheimer’s disease and other forms of dementia are marked by a slow decline, ABI occurs more suddenly and may include a loss of executive function and attention.
“With a brain injury, you’re doing fine, and then some event happens (in this case COVID), and immediately after that, your cognitive function is different,” said Dr. Jackson.
Additionally, ABI is an actual diagnosis, whereas brain fog is not.
“With a brain injury, there’s a treatment pathway for cognitive rehabilitation,” said Dr. Jackson.
Treatments may include speech, cognitive, and occupational therapy as well as meeting with a neuropsychiatrist for treatment of the mental and behavioral disorders that may result. Dr. Jackson said that while many patients aren’t functioning cognitively or physically at 100%, they can make enough strides that they don’t have to give up things such as driving and, in some cases, their jobs.

How small practices are surviving and thriving, part 1
Key takeaways
- Small-town physicians mostly love their practices; they are close to their patients and community, have the opportunity to practice very varied medicine, and feel like they make a difference. But they also struggle with many issues.
- Small practices are at a disadvantage when it comes to negotiating reimbursements.
- Resources such as access to specialists, equipment, and specialty meds put small-town docs in more precarious situations.
The challenges are mounting for physicians in small-town practices and rural areas, with private equity buying up many practices, the cost of overhead rising, and increased stress in attracting top talent. In the first of a two-part series, this news organization spoke to physicians in small towns around the country to identify some of the pain points squeezing small-town practices’ profits and making patient care more difficult.
Here are how physicians are working to offset the challenges and to make their small-town practices more rewarding.
Low reimbursements remain challenging
Jennifer Bacani McKenney, MD, owner of Fredonia Family Care, a private family medicine practice in Fredonia, Kan. (population 2,132), loves having close relationships with her patients and being an integral part of the community. However, she said that owning the only clinic in her town, which is 90 miles from Wichita, limits her power when negotiating for reimbursements.
“We don’t have bargaining power, so we often will end up getting terribly low reimbursements, especially for Medicaid,” she said. “We pay the price for not being part of a big health system.”
To bolster her ability to get reimbursement price concessions, her practice – which was initially started by her father and now includes four physicians – joined an accountable care organization in 2016.
“By joining other private practices around the state, we made some gains,” said Dr. McKenney, who was born in the hospital where she now works. “It enabled us to sit at the table with Blue Cross/Blue Shield of Kansas, for example, and have conversations that they listen to.”
Talent recruitment is an ongoing issue
For Ann Lima, MD, a family physician who came to Orofino, Idaho (population 3,000), 8 years ago after her residency in Ventura, Calif., practicing small-town medicine and seeing patients with a myriad of medical issues is a fulfilling challenge, but finding trained providers to join her practice remains problematic.
That’s because the physicians in her practice need to be nimble and to be able to routinely pivot from primary care to obstetrics to emergency medicine, owing to the nature of small-town practicing.
“It’s challenging in terms of finding people who are able to stay on top of all facets of hospital and acute care emergency care as well as OB and primary care,” she said. She noted that, for patients who require additional care, the nearest cities are Spokane, Wash., and Coeur D’Alene, Idaho, both approximately 3 hours away.
“It’s a challenge to find well-trained family physicians who want to do this diverse type of medicine.”
When it comes to staffing at her clinic, Dr. McKenney said it’s been more efficient to train employees from the ground up than try to find health care workers who already have significant experience.
“Right now, I have two 19-year-olds, a 21-year-old, and a 24-year-old working for me,” Dr. McKenney said of her clinic staff, which currently includes four doctors, a nurse practitioner, and 14 employees. “I hired the 19-year-old at age 17 and taught her to be a medical assistant.”
In addition to difficulty in recruiting physicians, nurses, and staff to a small-town practice, trying to find affordable housing makes it difficult to attract staffing in certain locations, said Frank Batcha, MD, a family physician in Hailey, Idaho (population 9,463), and chief of staff at St. Luke’s Wood River Regional Hospital in Ketchum, Idaho, where he has worked since the 1990s.
“We’re a resort community, so housing is unaffordable for somebody with an entry-level job,” he said. The region, a valley that includes Sun Valley, a popular ski resort with about 22,000 residents, is home to a handful of celebrities. It’s a popular destination spot and makes for a beautiful back country to call home.
“But it’s difficult to recruit physicians out of residency for this reason,” said Dr. Batcha. “We call it the scenery tax. It comes with a price.” Idaho is 49th out of 50th in physicians per capita for the entire United States.
Resources can be scarce
Another stressor for rural and small-town physicians is access to specialists, resources, and, in some cases, vital equipment.
“We have a general surgeon but no other specialty care,” Dr. Lima said. “This means that we can do acute appendicitis, we can take out gall bladders and do hernia repairs locally, but for significant trauma care and for patients who are very sick with ICU needs, we have to transfer them.”
Weather is also a huge factor that can affect ground ambulance or helicopter travel to a larger hospital.
“If there’s a storm, instead of a 45-minute transfer via helicopter, it’s a 3½ hour drive along mountain and river roads,” said Dr. Lima.
Ultimately, Dr. McKenney wished colleagues better understood the challenges facing rural physicians.
“When I transfer a patient from my hospital to a bigger facility, it’s because I don’t have certain medications on hand or an MRI ready to go,” she said. “It’s not that I don’t know what I’m doing.”
In addition, when she calls for a consult or sends a patient to a larger facility, it’s always because of a lack of resources.
“As rural physicians, we are really well educated and well trained,” she said “Our issue is that we’re practicing in a place with fewer things. But, when we call upon you, just know that we’ve tried everything we can first.”
Dr. McKenney lives and works happily in the town she grew up in and said no place could have given her a warmer welcome. In fact, while she was still finishing school, the townspeople campaigned to get her to come back and practice there – hard to come by that in a big city.
Small-town physicians offered five tactics for making a small-town practice work successfully:
- Develop relationships with specialists in your nearest large facility for referrals.
- Consider joining an ACO to improve work flow, diversify revenue streams, and maintain independence.
- Create a culture that’s welcoming to all incoming young professionals.
- Host medical students and residents as part of their education. “If they learn about your community, your practice, and rural healthcare early on, they will be more likely to be interested in coming back to serve that same community,” said Dr. McKenney.
- Recruit more than one physician if possible. “It’s really scary for new physicians to go out and practice on their own right out of training. Most rural communities need more than one more doctor anyway, and this gives them a built-in support system from the beginning,” said Dr. McKenney.

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.
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.
“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).

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.

A tiny patch may someday do your patients’ lab work
A smartwatch can tell a lot about a person’s health, but for guarding against big threats like diabetes and heart disease, blood tests remain the gold standard – for now.
Someday, a wearable patch could give patients and doctors the same information, minus the poke in the arm and the schlep to the medical lab.
The patch will track markers in interstitial fluid.
Continuous glucose monitors have already provided this glimpse into the future, by using interstitial fluid to track blood glucose levels in real time.
Now scientists are asking: What else could this tech help us measure?
“The vision is eventually to develop a lab under the skin,” said Joseph Wang, PhD, professor of nanoengineering at the University of California San Diego.
The result:
How does it work?
Sweat and saliva may be easier to get to, but interstitial fluid is a better mirror for blood. It leaks from tiny blood vessels (capillaries), and it carries nutrients to and removes waste from your skin.
To capture this fluid, each monitor has either a tiny wire or an array of less-than-a-millimeter-long microneedles that penetrate the skin for days, weeks, or however long you wear it. “You don’t feel it,” Dr. Wang said. “Once you place it on the skin, you forget about it.”
The microneedles or wires are made from a polymer that sucks up the fluid, which flows to a biochemical sensor targeting the marker you want to measure.
The earliest patents for this technology date back to the 1990s (the first wearable glucose monitors for home use rolled out in the 2000s), but sensors have come a long way since then, becoming smaller, more accurate, and more sophisticated.
Glucose sensors use an enzyme that reacts to glucose to reveal its concentration in the blood. Researcher Jason Heikenfeld, PhD, and his team at the University of Cincinnati focus on “aptamers,” short single strands of DNA that bind to target molecules. “You can leverage the body’s own ability to generate stuff to grab a needle in a haystack,” he said.
The bigger picture
As our population ages and health care costs spiral, and our medical infrastructure and labor force are stretched thin, we’re seeing a push for decentralized medicine, Dr. Heikenfeld said. Like other at-home monitoring technologies, interstitial fluid sensing promises convenience and better access to care.
“There’s a lot you can do over telemedicine, over the phone,” said Justin T. Baca, MD, PhD, associate professor at the University of New Mexico, Albuquerque. “But we still haven’t figured out how to collect reliable biosamples and analyze them remotely.”
Unlike a traditional blood test, which gives a health snapshot for a single point in time, these devices track data continuously, revealing trends and helping you spot oncoming threats earlier.
Take ketones, for example. Dr. Baca and others are using interstitial fluid to continuously detect ketone levels in the blood, potentially enabling us to catch diabetic ketoacidosis sooner.
“It’s potentially like an early warning sign that somebody needs to get either checked out or get rehydrated or get some insulin; kind of an early diagnostic to avoid hospital visits later on,” Dr. Baca said.
Here’s what else this tech could help us do:
Chronic disease management
Seeing the health impact of medication and diet in real time could motivate patients to stick to their treatment plans, Dr. Heikenfeld said. Researchers in Taiwan are developing a test that could help people with chronic kidney disease track levels of cystatin C, a protein that goes up as kidney function declines. Heart disease patients could watch their cholesterol levels drop over time, and of course, diabetes patients can already track glucose.
Prescription drug monitoring
Providers could monitor drug levels in a patient’s body – like antibiotics for an infection – to see how it’s being metabolized, and adjust the dose as needed, Dr. Heikenfeld said.
Stress and hormone therapy
Interstitial fluid could help us measure hormone levels, such as the stress hormone cortisol.
Scientists in the United Kingdom and Norway developed a waist-worn device that collects interstitial fluid samples continuously for up to 3 days. In their study, samples were sent out for analysis, but someday the device could be equipped with a sensor to monitor a single hormone in real time, said study author Thomas Upton, PhD, a clinical research fellow at the University of Bristol in England. “There is a lot of interest in real-time cortisol monitoring,” he said.
Among those who could benefit: patients with hormone deficiencies, night shift workers with disturbed circadian rhythms, or anyone who wants to keep tabs on their stress response.
Human performance and wellness
Athletes could use glucose and lactate monitors to optimize training, recovery time, and diet. For those on the keto diet, a monitor could help them adjust their carb intake based on their ketone levels. Abbott’s Analyte Ventures group is working on blood alcohol sensors, helpful to anyone who wants to avoid overindulging.
When will this be ready for clinical use?
Early research has been promising, but much more is needed before interstitial fluid sensors can be verified and approved.
Manufacturing will be a challenge. Producing these sensors at scale, without sacrificing consistency or quality, won’t be cheap, said Dr. Heikenfeld. Today’s continuous glucose monitors took decades and hundreds of millions of dollars to develop.
Still, the groundwork has been laid.
“As we all pivot more towards interstitial fluid, there’s a proven roadmap of success that the big diagnostic companies over decades have cut their teeth on,” said Dr. Heikenfeld.
For now, scientists are refining sensors and figuring out how to protect them from other body fluids while in use, Dr. Wang said. But if it all comes together, the result could be game-changing.
Dr. Wang’s lab is developing a system that can monitor glucose and lactate or glucose and alcohol – which could become available in as little as 2 years, he said.
In the next decade, Dr. Wang predicted, we’ll be able to measure a dozen markers with one simple patch.
