The gas stove: Friend or foe?
Diffuse Lung Disease and Lung Transplant Network
Occupational and Environmental Health Section
The kitchen is considered the heart of the home, but recent discoveries have raised concerns about whether this beloved space might also pose hidden health risks. Gas stoves, present in 38% of U.S. homes, generate multiple pollutants including nitrogen dioxide (NO₂), a known respiratory irritant.1 Studies have identified a correlation between NO₂ levels and respiratory conditions, with children being particularly vulnerable.2 The association between domestic NO₂ exposure from gas stoves and conditions such as asthma has led to increased scrutiny of indoor air quality.
Studies have demonstrated that households using gas stoves have higher indoor NO₂ levels, with levels that far exceed the EPA national ambient air quality standards.3 While the predominance of studies have looked at a correlation with pediatric pulmonary processes, there is also evidence of increased lung function loss in patients who smoke and have COPD.4
Switching from gas to electric stoves is one proposed solution to mitigate exposure to NO₂. Evidence suggests that electric stoves significantly reduce indoor NO₂ levels, lowering the risk of respiratory illnesses.
Another proposed solution has been to utilize hoods; however, capture efficiency is variable and some recycle the air and return it indoors.5 While existing data indicates a connection between gas stove use and respiratory health risks, conclusive evidence examining the magnitude and mechanisms linking these factors to chronic lung diseases is still needed. Comprehensive studies will help determine whether the kitchen staple—a gas stove—is indeed a friend or a foe to our respiratory health.

Prediction models in sepsis
Critical Care Network
Sepsis/Shock Section
Early recognition is the linchpin of sepsis management, as mortality from sepsis increases by 4% to 9% for every hour that diagnosis and treatment are delayed.1,2 Artificial intelligence (AI) and machine learning (ML) are increasingly featured in discussions and publications about sepsis care. Already ML models are embedded in electronic medical records (EMR), driving best-practice advisories that are presented to users.3 Epic, the EMR that serves over half of patients in the US, offers its own proprietary cognitive computing model for early detection.
As ML permeates the critical care space, it is increasingly important that clinicians understand the limitations of these models. Recently Kamran et al (NEJM AI) evaluated the Epic sepsis model with disappointing results after excluding cases already recognized by clinicians. The model achieved a positive predictive value of 5%, and 80% of high-risk sepsis cases were missed.3
An application study by Lilly et al (CHEST) showed that an ML model for clinically actionable events was more accurate with less alarm burden when compared to biomedical monitor alarms or telemedicine systems.4 The clinical utility of this model, however, remains questionable; presumably by the time a patient monitor has alarmed, the term “early recognition” can no longer be applied. In this study a significantly elevated false-positive rate required clinicians to review all cases prior to action.
ML models seem to offer incredible potential to clinicians. How they fit into current practice, however, deserves careful consideration. It may be that we just are not there yet.

Lung ultrasound: An indispensable yet underutilized tool
Thoracic Oncology and Chest Procedures Network
Ultrasound and Chest Imaging Section
An assessment using bedside thoracic ultrasound (TUS) improves diagnostic evaluation and therapeutic management in critically ill patients without undue risk. With changes in diagnosis occurring in 23% of cases and alterations in management in 39% of critically ill patients, TUS can improve length of stay, reduce complications, minimize delays in therapy, and lower hospitalization costs.1 Compared with its cardiac counterpart, attaining proficiency in lung ultrasound (LUS) is easier.2 Intensivists are at risk of forgoing mastering LUS in favor of developing more difficult skills. Proficiency in LUS is essential, as more than half of TUS evaluations are for respiratory complaints and most findings are pulmonary.1
A quick bedside assessment outperforms chest radiographs and available clinical scores in distinguishing pneumonia from atelectasis. The presence of dynamic air bronchograms within the consolidation is 45% sensitive and 99% specific for pneumonia over atelectasis.3 When air bronchograms are static, the presence of flow on color Doppler is 98% sensitive and 68% specific for pneumonia over atelectasis. Similarly, a closer look at the pleural lining shows more than the presence or absence of lung sliding. The presence of fragmentation, irregularity, or thickening of pleural lines provides 100% specificity in discriminating a noncardiogenic interstitial pathology from cardiogenic pulmonary edema.4
LUS is the workhorse and unsung hero of point-of-care ultrasound. In the last year, LUS has shown utility beyond evaluation for pneumothorax, pulmonary edema, and pleural effusion. Its potential impact on diagnosis and management is still growing. We just need to take a closer look.

Doctors Seek Additional Obesity Training in Wake of Obesity Patient Boom
Gitanjali Srivastava, MD, professor of medicine, pediatrics, and surgery, and medical director of obesity medicine at Vanderbilt University School of Medicine in Nashville, Tennessee, was nearly 10 years into practicing pediatric medicine when she graduated from the obesity medicine fellowship at Massachusetts General Hospital in Boston in 2013. “We were the very first sort of fellows to speak of then; there were no standards or curriculum,” she said.
Obesity was already epidemic, but stigma and bias were still pervasive in the medical community and within the public. After graduating, Dr. Srivastava spent months vying for a position with hospital CEOs. She traveled across the country explaining the specialty and its value, going into detail about the budget, business model, space requirement, and revenue potential of obesity medicine.
Today marks a very different era.
Obesity medicine is exploding. Patients are spilling into doctors’ offices looking for obesity treatment. Healthcare systems are seeking out obesity specialists and building metabolic health centers. Next month, another 2115 doctors from primary care, surgery, orthopedics, pediatrics, fertility, endocrinology, and beyond will sit for the 2024 exam. The once niche specialty is quickly becoming intertwined with most of modern medicine.
The Need to Treat
It’s no mystery that the rapid expansion of obesity medicine coincides with the US Food and Drug Administration’s approval of GLP-1 injections. The drugs’ radical weight loss properties have captured headlines and driven up patient demand. Meanwhile, doctors are finally able to offer effective treatment for a disease that affects 40% of US adults.
“We are finally treating it as a chronic disease, not as a lifestyle,” said Marcio Griebeler, MD, director of the obesity medicine fellowship at the Cleveland Clinic. And “I think it’s fulfilling for physicians,” he said.
For so long, the advice for obesity was about lifestyle. Move more, eat less, and harness willpower, “which really is a fallacy,” said Kimberly Gudzune, MD, MPH, an obesity medicine specialist and chief medical officer for the American Board of Obesity Medicine (ABOM) Foundation. For people with obesity, “your brain is operating differently,” she said. “Your body really is set up to work against you.”
Brianna Johnson-Rabbett, MD, medical director of the ABOM, told this news organization that with the advent of GLP-1s, “there’s a clearer recognition that obesity is a disease that needs to be treated like other diseases.” Some of that is thanks to clinical trial data showing that just as with other diseases such as high blood pressure or diabetes, obesity can be treated with medication and it resurges when the medication is stopped, she said.
Doctors don’t have to go looking for patients with obesity, dr. Griebeler added. Now that treatment options exist, they’re showing up in droves at the doctor’s office — all the doctors’ offices. In primary care, endocrinology, surgery, pediatrics — a wide variety of doctors are being asked about obesity drugs, Dr. Griebeler noted.
And while doctors are often just as excited as patients about the potential for treatment, many find themselves under-equipped when it comes to obesity. “More physicians are ... recognizing the value in treating this, and some are realizing, “Oh gosh, I never learned how to do this,” said Dr. Gudzune.
Information Patients Have Been Waiting For
Medical training has traditionally devoted minimal, if any, curriculum to obesity and metabolism. “To be honest, we didn’t really cover this at all in my training,” said Nina Paddu, MD, obesity medicine specialist at Maimonides Medical Center in New York City who finished her training only 2 years ago. “The guidance even in residency was ‘let’s send them to nutrition’ and ‘recommend exercising.’ ”
In addition to the medical education gap, until recently there was a “paucity of robust evidence,” Dr. Srivastava said. Leaders in the field wanted to establish standards and guidelines, but there wasn’t enough strong evidence on obesity and its treatments to build them, she said.
Only in the last 5 years or so has the evidence-based understanding of obesity’s pathophysiology truly accelerated: The brain’s driving roles, its interplay with hormones, and its interactions with other diseases. “We are just at the cusp of understanding all the different factors,” Dr. Gudzune said.
But already endocrinologists, surgeons, fertility specialists, gynecologists, and oncologists, to name a few, see the critical overlap with their own field. “Conditions were once suspected of being intertwined [with obesity], and now we have data to connect them,” Dr. Srivastava said. For example, there’s now data connecting semaglutide to a 20% reduction in cardiovascular events for people with obesity. That’s a game changer for multiple specialties, she told this news organization.
Getting Trained in Obesity Management
The recent uptick in obesity insights and increased patient need has doctors from every career stage seeking additional training.
The ABOM offers two board certification pathways: 60 hours of CME credits or a 12-month fellowship. Both paths require doctors to pass the board’s exam.
Many doctors incorporate the training into their existing practice. The CME credit pathway, especially, is designed to help get doctors up to speed without requiring them to upend their lives for a fellowship.
Dr. Srivastava said that the fellowship is more consuming and immersive. While it’s often younger doctors just out of training who apply to fellowship, every year, “I’m astonished at the number of talented physicians with clinical and research experience who want to immerse themselves in a fellowship experience.”
Some doctors return to their previous specialties after fellowship. But many will go on to take obesity medicine–specific roles or set aside clinic hours for obesity medicine. Their credentials are “really attractive to institutions, especially those looking to open up obesity medicine or weight management programs,” said Dr. Srivastava.
Dr. Paddu, who finished her obesity medicine fellowship this year, said there are a variety of obesity medicine jobs to choose from — far different from Dr. Srivastava’s job search 15 years ago. Dr. Paddu’s new role combines 2 days of primary care with 2 days devoted to obesity medicine and 1 day each week set aside for administrative work so she can build up the hospital’s new metabolic health clinic.
Still Not Enough Obesity Specialists
As with all things, rapid growth requires careful oversight. “Part of the responsibility of the board is to think critically of how the field is growing” and conduct ongoing monitoring, Dr. Gudzune said.
This is also why the board’s credentials are time-limited and must be recertified, Dr. Johnson-Rabbett added.
But even with the rise in certified doctors and obesity medicine positions, the 8263 doctors certified by ABOM are only a tiny fraction of US physicians. As a result, there’s genuine likelihood that many patients seeking GLP-1s or other obesity treatment don’t yet have access to the holistic care they need. Plus, doctors may still not have obesity expertise within their networks.
“The field has grown rapidly, but it’s still such a small field relative to the patient need,” said Dr. Gudzune.

But already endocrinologists, surgeons, fertility specialists, gynecologists, and oncologists, to name a few, see the critical overlap with their own field. “Conditions were once suspected of being intertwined [with obesity], and now we have data to connect them,” Dr. Srivastava said. For example, there’s now data connecting semaglutide to a 20% reduction in cardiovascular events for people with obesity. That’s a game changer for multiple specialties, she told this news organization.
Getting Trained in Obesity Management
The recent uptick in obesity insights and increased patient need has doctors from every career stage seeking additional training.
The ABOM offers two board certification pathways: 60 hours of CME credits or a 12-month fellowship. Both paths require doctors to pass the board’s exam.
Many doctors incorporate the training into their existing practice. The CME credit pathway, especially, is designed to help get doctors up to speed without requiring them to upend their lives for a fellowship.
Dr. Srivastava said that the fellowship is more consuming and immersive. While it’s often younger doctors just out of training who apply to fellowship, every year, “I’m astonished at the number of talented physicians with clinical and research experience who want to immerse themselves in a fellowship experience.”
Some doctors return to their previous specialties after fellowship. But many will go on to take obesity medicine–specific roles or set aside clinic hours for obesity medicine. Their credentials are “really attractive to institutions, especially those looking to open up obesity medicine or weight management programs,” said Dr. Srivastava.
Dr. Paddu, who finished her obesity medicine fellowship this year, said there are a variety of obesity medicine jobs to choose from — far different from Dr. Srivastava’s job search 15 years ago. Dr. Paddu’s new role combines 2 days of primary care with 2 days devoted to obesity medicine and 1 day each week set aside for administrative work so she can build up the hospital’s new metabolic health clinic.
Still Not Enough Obesity Specialists
As with all things, rapid growth requires careful oversight. “Part of the responsibility of the board is to think critically of how the field is growing” and conduct ongoing monitoring, Dr. Gudzune said.
This is also why the board’s credentials are time-limited and must be recertified, Dr. Johnson-Rabbett added.
But even with the rise in certified doctors and obesity medicine positions, the 8263 doctors certified by ABOM are only a tiny fraction of US physicians. As a result, there’s genuine likelihood that many patients seeking GLP-1s or other obesity treatment don’t yet have access to the holistic care they need. Plus, doctors may still not have obesity expertise within their networks.
“The field has grown rapidly, but it’s still such a small field relative to the patient need,” said Dr. Gudzune.

Gitanjali Srivastava, MD, professor of medicine, pediatrics, and surgery, and medical director of obesity medicine at Vanderbilt University School of Medicine in Nashville, Tennessee, was nearly 10 years into practicing pediatric medicine when she graduated from the obesity medicine fellowship at Massachusetts General Hospital in Boston in 2013. “We were the very first sort of fellows to speak of then; there were no standards or curriculum,” she said.
Obesity was already epidemic, but stigma and bias were still pervasive in the medical community and within the public. After graduating, Dr. Srivastava spent months vying for a position with hospital CEOs. She traveled across the country explaining the specialty and its value, going into detail about the budget, business model, space requirement, and revenue potential of obesity medicine.
Today marks a very different era.
Obesity medicine is exploding. Patients are spilling into doctors’ offices looking for obesity treatment. Healthcare systems are seeking out obesity specialists and building metabolic health centers. Next month, another 2115 doctors from primary care, surgery, orthopedics, pediatrics, fertility, endocrinology, and beyond will sit for the 2024 exam. The once niche specialty is quickly becoming intertwined with most of modern medicine.
The Need to Treat
It’s no mystery that the rapid expansion of obesity medicine coincides with the US Food and Drug Administration’s approval of GLP-1 injections. The drugs’ radical weight loss properties have captured headlines and driven up patient demand. Meanwhile, doctors are finally able to offer effective treatment for a disease that affects 40% of US adults.
“We are finally treating it as a chronic disease, not as a lifestyle,” said Marcio Griebeler, MD, director of the obesity medicine fellowship at the Cleveland Clinic. And “I think it’s fulfilling for physicians,” he said.
For so long, the advice for obesity was about lifestyle. Move more, eat less, and harness willpower, “which really is a fallacy,” said Kimberly Gudzune, MD, MPH, an obesity medicine specialist and chief medical officer for the American Board of Obesity Medicine (ABOM) Foundation. For people with obesity, “your brain is operating differently,” she said. “Your body really is set up to work against you.”
Brianna Johnson-Rabbett, MD, medical director of the ABOM, told this news organization that with the advent of GLP-1s, “there’s a clearer recognition that obesity is a disease that needs to be treated like other diseases.” Some of that is thanks to clinical trial data showing that just as with other diseases such as high blood pressure or diabetes, obesity can be treated with medication and it resurges when the medication is stopped, she said.
Doctors don’t have to go looking for patients with obesity, dr. Griebeler added. Now that treatment options exist, they’re showing up in droves at the doctor’s office — all the doctors’ offices. In primary care, endocrinology, surgery, pediatrics — a wide variety of doctors are being asked about obesity drugs, Dr. Griebeler noted.
And while doctors are often just as excited as patients about the potential for treatment, many find themselves under-equipped when it comes to obesity. “More physicians are ... recognizing the value in treating this, and some are realizing, “Oh gosh, I never learned how to do this,” said Dr. Gudzune.
Information Patients Have Been Waiting For
Medical training has traditionally devoted minimal, if any, curriculum to obesity and metabolism. “To be honest, we didn’t really cover this at all in my training,” said Nina Paddu, MD, obesity medicine specialist at Maimonides Medical Center in New York City who finished her training only 2 years ago. “The guidance even in residency was ‘let’s send them to nutrition’ and ‘recommend exercising.’ ”
In addition to the medical education gap, until recently there was a “paucity of robust evidence,” Dr. Srivastava said. Leaders in the field wanted to establish standards and guidelines, but there wasn’t enough strong evidence on obesity and its treatments to build them, she said.
Only in the last 5 years or so has the evidence-based understanding of obesity’s pathophysiology truly accelerated: The brain’s driving roles, its interplay with hormones, and its interactions with other diseases. “We are just at the cusp of understanding all the different factors,” Dr. Gudzune said.

New Hypertension Approach Hits Multiple Targets at Low Dose
LONDON — , according to experts evaluating the new approach.
This multidrug strategy — in which ultralow-dose triple combinations can be used as a starting treatment and four full-dose combinations can be used to treat resistant hypertension — has shown an impressive ability to lower blood pressure in several new studies.
But will it catch on as a routine treatment recommendation in current practice?
Studies of treatment strategies that involve an ultralow quarter dose of three drugs that lower blood pressure and then escalation to a half-dose triple combination and then to a full-dose triple combination, all given as a single pill, were presented at the European Society of Cardiology (ESC) Congress 2024. Another strategy presented involves a four-drug full-dose combination in patients with resistant hypertension.
Start With Low Doses of Three Drugs
The triple-combination pill contains telmisartan (an angiotensin blocker), amlodipine (a calcium channel blocker), and indapamide (a diuretic). The three medications are used at three doses: Quarter, half, and standard.
“The idea is to start treatment with a little bit of the three main drug classes instead of the full dose of one drug and then to increase the triple-combination doses as required to get to blood pressure goal,” said Anthony Rodgers, PhD, from the team at The George Institute for Global Health, Sydney, Australia, that is developing this triple-combination product.
“Using three different mechanisms right from the beginning covers all the bases and leads to improved blood pressure reduction while just using very small doses of each agent. This represents a completely new approach that could transform the management of hypertension,” he reported.
Single-pill triple-combination antihypertensive formulations exist already, but the component drugs are all at standard doses. Such combinations were designed to improve adherence in patients with hard-to-control blood pressure who need more than two full-dose medications, he explained.
“We are suggesting a completely different concept using much lower doses of the triple combination right from the beginning of treatment,” Dr. Rodgers explained. “Convenience and adherence will be an added advantage, but there’s more to it than that. It’s about combining the different mechanisms of three separate drug classes to get a better antihypertensive effect and being able to do this right from the start of treatment in patients with mildly elevated blood pressure, as well as those with higher levels.”
Proof-of-concept trials of this approach have been conducted, but no commercial low-dose triple-combination product has been available.
The George Institute is now developing such a product — through George Medicines, its commercial arm — with the aim of bringing the triple-combination pill to market in both high- and low-income countries. An approval submission has been filed in the United States.
Dr. Rodgers presented two studies that assessed the triple combination. One showed that the quarter dose reduced blood pressure significantly better than placebo in patients with mildly elevated blood pressure. The second showed that half and standard doses of the three medications were more effective at lowering blood pressure than three dual combinations at the same doses.
The VERONICA Trial
The triple combination was also assessed in the VERONICA study, which showed that among Black adults in Nigeria with uncontrolled hypertension, blood pressure was lower and control was better with the low-dose triple-combination pill than with standard care, and tolerability was good.
In VERONICA, recently published in JAMA, 300 patients with a mean baseline blood pressure of 151/97 mm Hg at home and 156/97 mm Hg in the clinic were randomly assigned to receive the triple-combination pill or standard care.
In the triple-combination group, patients started with the quarter-dose pill, then accelerated, as necessary, to the half-dose and standard-dose pills.
In the standard care group, patients started with amlodipine (5 mg), which was stepped up at monthly intervals so patients could achieve a target blood pressure < 140/90 mm Hg as follows: Amlodipine (5 mg) plus losartan (50 mg); then amlodipine (10 mg) plus losartan (100 mg); then amlodipine (10 mg), losartan (100 mg), plus hydrochlorothiazide (25 mg); and finally referral to a specialist if the target blood pressure was still not achieved.
At month 6, mean home systolic blood pressure was, on average, 31 mm Hg lower in the triple-combination group and 26 mm Hg lower in the standard care group (adjusted difference, −5.8 mm Hg; P < .001).
More patients in the triple-combination group than in the standard care group achieved clinic blood pressure control, defined as blood pressure < 140/90 mm Hg (82% vs 72%), and more patients achieved home blood pressure control, defined as blood pressure below 130/80 mm Hg (62% vs 28%).
No participants discontinued treatment due to adverse events, and adverse events of special interest were reported by just 2% and 3% patients in the triple-combination and standard care groups, respectively.
At month 6, however, more participants in the triple-combination group than in the standard care group had serum potassium levels < 3.5 mmol/L (34% vs 18%), although fewer participants in both the groups had potassium levels < 3.0 mmol/L (10% vs 5%).
Hypokalemia may be the consequence of low dietary potassium intake in Africa, and co-administration with potassium-enriched salt substitution should be evaluated, said Dike Ojji, MBBS, PhD, University of Abuja, Nigeria, who was the lead investigator of VERONICA.
“These findings have broad clinical and public health implications, given that improved hypertension control is a priority in Africa and globally. The results underscore the need for combination therapy to be the cornerstone of effective treatment regimens,” Dr. Ojji said.
Missed Targets
“It has taken a long time for the penny to drop as to why the existing antihypertensive treatment paradigm does not work so well,” Dr. Rodgers pointed out. “What tends to happen in clinical practice is that people start on one drug and blood pressure falls a bit, then no further action is taken. But this is not usually enough to get to target. With our approach of using three drugs at low doses straight away, we can often get the blood pressure controlled to target much more quickly with one tablet.”
Low doses of the triple-combination pill should also have a favorable adverse-effect profile and fewer drug interactions, as these issues are generally seen much more frequently with higher doses of drugs, he explained.
This low-dose triple-combination approach could help manage the current epidemic of hypertension and cardiometabolic disease, said Pam Taub, MD, director of preventive cardiology at UC San Diego Health System.
“We are in a new era of cardiometabolic disease, and one of the fundamental drivers of atherosclerotic cardiovascular disease is hypertension, which is prevalent in patients with diabetes, in those with obesity, and is a contributor to chronic kidney disease,” she said.
“We really need to be addressing hypertension very early to prevent this end-organ damage, but because hypertension tends to occur alongside multiple other comorbidities, patients are often on many different medications and are overwhelmed by the burden of polypharmacy.”
Dr. Taub described this triple-combination approach as “looking at hypertension treatment through a new lens.”
“We’ve always been taught to maximize the dose of one agent before we go to a new agent,” she said. “These studies are fundamentally challenging that paradigm. From a pathophysiological and mechanistic perspective, we are seeing that lower doses of different medications can really harness some unique synergistic mechanisms, which can be beneficial for patients.”
But not all experts are convinced that this approach will be a popular option in all countries.
Although this approach makes sense, in that the different agents work synergistically to give a better antihypertensive effect, many physicians could be uncomfortable with the idea of giving multiple medications straight off as the first step of treatment, said Eugene Yang, MD, from the University of Washington in Seattle.
If the patient develops a side effect, it will not be clear which medication is causing it, making it difficult to know which one to stop, he pointed out.
“These studies confirm that a low-dose multidrug-combination pill is effective at lowering blood pressure, but we already have previous studies showing this,” he added. “The issue is how we translate this into patient care. It would be great if we could get people to use it, but I think concerns from both clinicians and patients about identifying the source of any side effects may be a stumbling block.”
The approach is more likely to be adopted in low- to middle-income countries, where there is limited access to healthcare and where the population-wide control of blood pressure makes sense, said Dr. Yang.
Most current guidelines now recommend initiating therapy with two agents, ideally, as a single-pill combination product. “We have finally acknowledged that the vast majority of patients need two drugs. That’s a good starting point. This low-dose triple combination could be an interesting new approach,” said Neil Poulter, MD, professor of preventive cardiovascular medicine at Imperial College London, England.
This approach is in line with the idea that single-pill combinations are the way forward for hypertension therapy, he added.
“The triple combination is attractive, in that you are never quite sure which particular mechanism is driving an individual’s elevated blood pressure, so if you can target three different mechanisms at the same time, you’ve got more chance of a good hit,” Dr. Poulter said.
“The VERONICA trial showed a very good result on lowering BP using this low-dose triple combination as a starting point and increasing quickly to single-pill combinations of triple half doses, then triple full doses, as required. But I think we need more evidence on how this compares to current practice than just this one study in Africa to make this an acceptable routine approach on a global level,” he said.
QUADRO: Four-Drug Combo in Resistant Hypertension
Another scenario in which single-pill antihypertensive combinations could be particularly useful is at the other end of the spectrum: The treatment of patients with resistant hypertension.
The QUADRO study showed that a single pill containing perindopril, indapamide, amlodipine, and bisoprolol is better at lowering blood pressure than the triple combination of perindopril, indapamide, and amlodipine.
The primary endpoint — office sitting systolic blood pressure at 16 weeks — was 8 mm Hg lower with the quadruple combination than with the triple combination. And mean ambulatory 24-hour systolic blood pressure was 7.5 mm Hg lower with the four-drug combination.
This was the first study of a single-pill quadruple combination in patients with resistant hypertension, which is a “difficult-to-treat condition demanding a high number of pills with not enough safe and practical options,” said Stefano Taddei, MD, from the University of Pisa, Italy, when he presented the study at the ESC meeting.
Using “four well-established drugs in a single-combination pill may improve adherence and should be an innovative solution for resistant and difficult-to-treat hypertensive patients,” he said.
Nonadherence is a big problem in patients with resistant hypertension. “It is really difficult to get patients to take three or four antihypertensive agents along with all the other medications they have for other comorbidities,” Dr. Taub pointed out. “We really need to think about combination formulations that reduce the pill burden for our patients.”
Around 10% patients with hypertension may require a fourth drug, so a four-drug single-pill combination therefore makes good sense, said Dr. Poulter.
But the choice of the fourth drug is the subject of debate. The PATHWAY trial showed spironolactone to be the most effective fourth agent, but it can cause side effects, such as gynecomastia and hyperkalemia.
“The beta-blocker in the four-drug combination product used in the QUADRO study may not be as effective as spironolactone at lowering blood pressure,” Dr. Poulter explained, noting that beta-blockers have known side effects. However, “they are often already recommended for patients with very common comorbidities, such as arrhythmias, history of MI, heart failure, angina. In that regard, it makes sense to have a beta-blocker in there.”
The four-drug combination used in the QUADRO study led to a bigger reduction — by 8 mm Hg — than the three-drug combination. “That’s pretty good. I thought this was a very useful and interesting study,” he said.
There could be a role for a four-drug combination product in resistant hypertension. “Whatever we can do to improve adherence and reduce blood pressure is good thing,” said Dr. Yang.
However, a mineralocorticoid receptor antagonist (such as spironolactone) might be better as the fourth drug; that is what is recommended in the resistant hypertension algorithm.
Lower Blood Pressure, Better Outcomes
“What we are seeing in these trials is that across a wide spectrum of patients with hypertension or resistant hypertension, combination pills are superior to standard practice for BP lowering, and that will lead to improved outcomes,” said Dr. Taub.
“For years, such single-pill combinations have been viewed as ‘bad medicine’ in hypertension,” Dr. Poulter added. “That is clearly not the case, as these studies are showing. And single-pill combination therapies are used extensively in practically every other area of medicine. We are starting to accept them now in the blood pressure community, and I think the use of triple and quadruple combinations, as in these studies, has a real logic to it. But for this approach to be useful, these single-pill combinations must be made available, cheaply, across the world, especially in low- and middle-income countries where hypertension rates are a particular problem.”

The four-drug combination used in the QUADRO study led to a bigger reduction — by 8 mm Hg — than the three-drug combination. “That’s pretty good. I thought this was a very useful and interesting study,” he said.
There could be a role for a four-drug combination product in resistant hypertension. “Whatever we can do to improve adherence and reduce blood pressure is good thing,” said Dr. Yang.
However, a mineralocorticoid receptor antagonist (such as spironolactone) might be better as the fourth drug; that is what is recommended in the resistant hypertension algorithm.
Lower Blood Pressure, Better Outcomes
“What we are seeing in these trials is that across a wide spectrum of patients with hypertension or resistant hypertension, combination pills are superior to standard practice for BP lowering, and that will lead to improved outcomes,” said Dr. Taub.
“For years, such single-pill combinations have been viewed as ‘bad medicine’ in hypertension,” Dr. Poulter added. “That is clearly not the case, as these studies are showing. And single-pill combination therapies are used extensively in practically every other area of medicine. We are starting to accept them now in the blood pressure community, and I think the use of triple and quadruple combinations, as in these studies, has a real logic to it. But for this approach to be useful, these single-pill combinations must be made available, cheaply, across the world, especially in low- and middle-income countries where hypertension rates are a particular problem.”

LONDON — , according to experts evaluating the new approach.
This multidrug strategy — in which ultralow-dose triple combinations can be used as a starting treatment and four full-dose combinations can be used to treat resistant hypertension — has shown an impressive ability to lower blood pressure in several new studies.
But will it catch on as a routine treatment recommendation in current practice?
Studies of treatment strategies that involve an ultralow quarter dose of three drugs that lower blood pressure and then escalation to a half-dose triple combination and then to a full-dose triple combination, all given as a single pill, were presented at the European Society of Cardiology (ESC) Congress 2024. Another strategy presented involves a four-drug full-dose combination in patients with resistant hypertension.
Start With Low Doses of Three Drugs
The triple-combination pill contains telmisartan (an angiotensin blocker), amlodipine (a calcium channel blocker), and indapamide (a diuretic). The three medications are used at three doses: Quarter, half, and standard.
“The idea is to start treatment with a little bit of the three main drug classes instead of the full dose of one drug and then to increase the triple-combination doses as required to get to blood pressure goal,” said Anthony Rodgers, PhD, from the team at The George Institute for Global Health, Sydney, Australia, that is developing this triple-combination product.
“Using three different mechanisms right from the beginning covers all the bases and leads to improved blood pressure reduction while just using very small doses of each agent. This represents a completely new approach that could transform the management of hypertension,” he reported.
Single-pill triple-combination antihypertensive formulations exist already, but the component drugs are all at standard doses. Such combinations were designed to improve adherence in patients with hard-to-control blood pressure who need more than two full-dose medications, he explained.
“We are suggesting a completely different concept using much lower doses of the triple combination right from the beginning of treatment,” Dr. Rodgers explained. “Convenience and adherence will be an added advantage, but there’s more to it than that. It’s about combining the different mechanisms of three separate drug classes to get a better antihypertensive effect and being able to do this right from the start of treatment in patients with mildly elevated blood pressure, as well as those with higher levels.”
Proof-of-concept trials of this approach have been conducted, but no commercial low-dose triple-combination product has been available.
The George Institute is now developing such a product — through George Medicines, its commercial arm — with the aim of bringing the triple-combination pill to market in both high- and low-income countries. An approval submission has been filed in the United States.
Dr. Rodgers presented two studies that assessed the triple combination. One showed that the quarter dose reduced blood pressure significantly better than placebo in patients with mildly elevated blood pressure. The second showed that half and standard doses of the three medications were more effective at lowering blood pressure than three dual combinations at the same doses.
The VERONICA Trial
The triple combination was also assessed in the VERONICA study, which showed that among Black adults in Nigeria with uncontrolled hypertension, blood pressure was lower and control was better with the low-dose triple-combination pill than with standard care, and tolerability was good.
In VERONICA, recently published in JAMA, 300 patients with a mean baseline blood pressure of 151/97 mm Hg at home and 156/97 mm Hg in the clinic were randomly assigned to receive the triple-combination pill or standard care.
In the triple-combination group, patients started with the quarter-dose pill, then accelerated, as necessary, to the half-dose and standard-dose pills.
In the standard care group, patients started with amlodipine (5 mg), which was stepped up at monthly intervals so patients could achieve a target blood pressure < 140/90 mm Hg as follows: Amlodipine (5 mg) plus losartan (50 mg); then amlodipine (10 mg) plus losartan (100 mg); then amlodipine (10 mg), losartan (100 mg), plus hydrochlorothiazide (25 mg); and finally referral to a specialist if the target blood pressure was still not achieved.
At month 6, mean home systolic blood pressure was, on average, 31 mm Hg lower in the triple-combination group and 26 mm Hg lower in the standard care group (adjusted difference, −5.8 mm Hg; P < .001).
More patients in the triple-combination group than in the standard care group achieved clinic blood pressure control, defined as blood pressure < 140/90 mm Hg (82% vs 72%), and more patients achieved home blood pressure control, defined as blood pressure below 130/80 mm Hg (62% vs 28%).
No participants discontinued treatment due to adverse events, and adverse events of special interest were reported by just 2% and 3% patients in the triple-combination and standard care groups, respectively.
At month 6, however, more participants in the triple-combination group than in the standard care group had serum potassium levels < 3.5 mmol/L (34% vs 18%), although fewer participants in both the groups had potassium levels < 3.0 mmol/L (10% vs 5%).
Hypokalemia may be the consequence of low dietary potassium intake in Africa, and co-administration with potassium-enriched salt substitution should be evaluated, said Dike Ojji, MBBS, PhD, University of Abuja, Nigeria, who was the lead investigator of VERONICA.
“These findings have broad clinical and public health implications, given that improved hypertension control is a priority in Africa and globally. The results underscore the need for combination therapy to be the cornerstone of effective treatment regimens,” Dr. Ojji said.
Missed Targets
“It has taken a long time for the penny to drop as to why the existing antihypertensive treatment paradigm does not work so well,” Dr. Rodgers pointed out. “What tends to happen in clinical practice is that people start on one drug and blood pressure falls a bit, then no further action is taken. But this is not usually enough to get to target. With our approach of using three drugs at low doses straight away, we can often get the blood pressure controlled to target much more quickly with one tablet.”
Low doses of the triple-combination pill should also have a favorable adverse-effect profile and fewer drug interactions, as these issues are generally seen much more frequently with higher doses of drugs, he explained.
This low-dose triple-combination approach could help manage the current epidemic of hypertension and cardiometabolic disease, said Pam Taub, MD, director of preventive cardiology at UC San Diego Health System.
“We are in a new era of cardiometabolic disease, and one of the fundamental drivers of atherosclerotic cardiovascular disease is hypertension, which is prevalent in patients with diabetes, in those with obesity, and is a contributor to chronic kidney disease,” she said.
“We really need to be addressing hypertension very early to prevent this end-organ damage, but because hypertension tends to occur alongside multiple other comorbidities, patients are often on many different medications and are overwhelmed by the burden of polypharmacy.”
Dr. Taub described this triple-combination approach as “looking at hypertension treatment through a new lens.”
“We’ve always been taught to maximize the dose of one agent before we go to a new agent,” she said. “These studies are fundamentally challenging that paradigm. From a pathophysiological and mechanistic perspective, we are seeing that lower doses of different medications can really harness some unique synergistic mechanisms, which can be beneficial for patients.”
But not all experts are convinced that this approach will be a popular option in all countries.
Although this approach makes sense, in that the different agents work synergistically to give a better antihypertensive effect, many physicians could be uncomfortable with the idea of giving multiple medications straight off as the first step of treatment, said Eugene Yang, MD, from the University of Washington in Seattle.
If the patient develops a side effect, it will not be clear which medication is causing it, making it difficult to know which one to stop, he pointed out.
“These studies confirm that a low-dose multidrug-combination pill is effective at lowering blood pressure, but we already have previous studies showing this,” he added. “The issue is how we translate this into patient care. It would be great if we could get people to use it, but I think concerns from both clinicians and patients about identifying the source of any side effects may be a stumbling block.”
The approach is more likely to be adopted in low- to middle-income countries, where there is limited access to healthcare and where the population-wide control of blood pressure makes sense, said Dr. Yang.
Most current guidelines now recommend initiating therapy with two agents, ideally, as a single-pill combination product. “We have finally acknowledged that the vast majority of patients need two drugs. That’s a good starting point. This low-dose triple combination could be an interesting new approach,” said Neil Poulter, MD, professor of preventive cardiovascular medicine at Imperial College London, England.
This approach is in line with the idea that single-pill combinations are the way forward for hypertension therapy, he added.
“The triple combination is attractive, in that you are never quite sure which particular mechanism is driving an individual’s elevated blood pressure, so if you can target three different mechanisms at the same time, you’ve got more chance of a good hit,” Dr. Poulter said.
“The VERONICA trial showed a very good result on lowering BP using this low-dose triple combination as a starting point and increasing quickly to single-pill combinations of triple half doses, then triple full doses, as required. But I think we need more evidence on how this compares to current practice than just this one study in Africa to make this an acceptable routine approach on a global level,” he said.
QUADRO: Four-Drug Combo in Resistant Hypertension
Another scenario in which single-pill antihypertensive combinations could be particularly useful is at the other end of the spectrum: The treatment of patients with resistant hypertension.
The QUADRO study showed that a single pill containing perindopril, indapamide, amlodipine, and bisoprolol is better at lowering blood pressure than the triple combination of perindopril, indapamide, and amlodipine.
The primary endpoint — office sitting systolic blood pressure at 16 weeks — was 8 mm Hg lower with the quadruple combination than with the triple combination. And mean ambulatory 24-hour systolic blood pressure was 7.5 mm Hg lower with the four-drug combination.
This was the first study of a single-pill quadruple combination in patients with resistant hypertension, which is a “difficult-to-treat condition demanding a high number of pills with not enough safe and practical options,” said Stefano Taddei, MD, from the University of Pisa, Italy, when he presented the study at the ESC meeting.
Using “four well-established drugs in a single-combination pill may improve adherence and should be an innovative solution for resistant and difficult-to-treat hypertensive patients,” he said.
Nonadherence is a big problem in patients with resistant hypertension. “It is really difficult to get patients to take three or four antihypertensive agents along with all the other medications they have for other comorbidities,” Dr. Taub pointed out. “We really need to think about combination formulations that reduce the pill burden for our patients.”
Around 10% patients with hypertension may require a fourth drug, so a four-drug single-pill combination therefore makes good sense, said Dr. Poulter.
But the choice of the fourth drug is the subject of debate. The PATHWAY trial showed spironolactone to be the most effective fourth agent, but it can cause side effects, such as gynecomastia and hyperkalemia.
“The beta-blocker in the four-drug combination product used in the QUADRO study may not be as effective as spironolactone at lowering blood pressure,” Dr. Poulter explained, noting that beta-blockers have known side effects. However, “they are often already recommended for patients with very common comorbidities, such as arrhythmias, history of MI, heart failure, angina. In that regard, it makes sense to have a beta-blocker in there.”
The four-drug combination used in the QUADRO study led to a bigger reduction — by 8 mm Hg — than the three-drug combination. “That’s pretty good. I thought this was a very useful and interesting study,” he said.
There could be a role for a four-drug combination product in resistant hypertension. “Whatever we can do to improve adherence and reduce blood pressure is good thing,” said Dr. Yang.
However, a mineralocorticoid receptor antagonist (such as spironolactone) might be better as the fourth drug; that is what is recommended in the resistant hypertension algorithm.

Antidepressants Linked to Improved Verbal Memory
MILAN — , a clinical effect linked to changes in serotonin 4 (5-HT4) receptor levels in the brain, as shown on PET.
These findings suggested there is a role for specifically targeting the 5-HT4 receptor to improve verbal memory in depression, said investigator Vibeke H. Dam, PhD, from Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.
“Verbal memory is often impaired in depression, and this has a lot of impact on patients’ ability to work and have a normal life. That’s why we’re so excited about this receptor in particular,” Dr. Dam said.
“If we can find a way to activate it more directly, we’re thinking this could be a way to treat this memory symptom that a lot of patients have and that currently we don’t really have a treatment for,” she added.
The findings were presented at the 37th European College of Neuropsychopharmacology (ECNP) Congress and recently published in Biological Psychiatry .
Largest Trial of Its Kind
The study is the largest single-site PET trial investigating serotonergic neurotransmission in major depressive disorder over the course of antidepressant treatment to date. It included 90 patients with moderate to severe depression who underwent baseline cognitive tests and brain scans to measure 5-HT4 receptor levels before starting their treatment with the selective serotonin reuptake inhibitor escitalopram.
Patients who showed no improvement in depressive symptoms after 4 weeks (n = 14), as assessed by the Hamilton Depression Rating Scale 6 (HAMD6), were switched to the serotonin-norepinephrine reuptake inhibitor duloxetine.
Both escitalopram and duloxetine inhibit the reuptake of 5-HT4, enhancing neurotransmitter activity; escitalopram primarily increases serotonin levels, while duloxetine increases both serotonin and norepinephrine levels.
The primary cognitive outcome measure was change in the Verbal Affective Memory Task 26. Secondary cognitive outcomes were change in working memory, reaction time, emotion recognition bias, and negative social emotion.
After 8 weeks of treatment, a subset of 40 patients repeated PET scans, and at 12 weeks, all patients repeated cognitive testing.
Matching neuroimaging and cognitive data were available for 88 patients at baseline and for 39 patients with rescan.
As expected, the study showed that antidepressant treatment resulted in the downregulation of 5-HT4 receptor levels. “One hypothesis is that if we increase the availability of serotonin [with treatment], downregulation of the receptors might be a response,” said Dr. Dam.
“What was interesting was that this was the effect across all patients, whether they [clinically] responded or not. So we see the medication does what it’s supposed to do in the brain.” But, she said, there was no association between 5-HT4 receptor levels and HAMD6 scores.
Gains in Verbal Memory
Although the downregulation of 5-HT4 did not correlate with somatic or mood symptoms, it did correlate with cognitive symptoms.
Interestingly, while most patients showed improvement in depressive symptoms — many reaching remission or recovery — they also experienced gains in verbal memory. However, these improvements were not correlated. It was possible for one to improve more than the other, with no apparent link between the two, said Dr. Dam.
“What was linked was how the brain responded to the medication for this particular receptor. So even though there is this downregulation of the receptor, there’s still a lot of activation of it, and our thinking is that it’s activation of the receptor that is the important bit.”
Work by other groups has shown that another medication, prucalopride, which is used to treat gastroparesis, can more directly activate the 5-HT4 receptor, and that the treatment of healthy volunteers with this medication can boost memory and learning, said Dr. Dam.
“We could repurpose this drug, and we’re currently looking for funding to test this in a wide variety of different groups such as concussion, diabetes, and depression.”
The study’s coinvestigator, Vibe G. Frokjaer, MD, said more research is required to understand the potential implications of the findings.
“Poor cognitive function is very hard to treat efficiently and may require extra treatment. This work points to the possibility of stimulating this specific receptor so that we can treat cognitive problems, even aside from whether or not the patient has overcome the core symptoms of depression,” she said in a release.
Commenting on the research, Philip Cowen, MD, professor of psychopharmacology at the University of Oxford, England, said in a release that in light of “recent controversies about the role of brain serotonin in clinical depression, it is noteworthy that the PET studies of the Copenhagen Group provide unequivocal evidence that brain 5-HT4 receptors are decreased in unmedicated depressed patients.
“Their work also demonstrates the intimate role of brain 5-HT4 receptors in cognitive function,” he added. “This confirms recent work from Oxford, showing that the 5-HT4 receptor stimulant, prucalopride — a drug licensed for the treatment of constipation — improves memory in both healthy participants and people at risk of depression,” he added.
The study was funded by the Innovation Fund Denmark, Research Fund of the Mental Health Services – Capital Region of Denmark, Independent Research Fund Denmark, Global Justice Foundation, Research Council of Rigshospitalet, Augustinus Foundation, Savværksejer Jeppe Juhl og hustru Ovita Juhls Mindelegat, Lundbeck Foundation, and H. Lundbeck A/S.
Dr. Dam reported serving as a speaker for H. Lundbeck. Frokjaer reported serving as a consultant for Sage Therapeutics and lecturer for H. Lundbeck, Janssen-Cilag, and Gedeon Richter. Study investigator Martin B. Jørgensen has given talks sponsored by Boehringer Ingelheim and Lundbeck Pharma. All other investigators reported no relevant disclosures.

FROM ECNP 2024
An Rx for Burnout, Grief, and Illness: Dance
In 2012, Tara Rynders’ sister was diagnosed with acute disseminated encephalomyelitis. For Ms. Rynders, a registered nurse in Denver, Colorado, the news was devastating.
“She was this beautiful 26-year-old woman, strong and healthy, and within 12 hours, she went into a coma and couldn’t move or speak,” Ms. Rynders remembered. She flew to her sister in Reno, Nevada, and moved into her intensive care unit room. The helplessness she felt wasn’t just as a sister, but as a healthcare provider.
“As a nurse, we love to fix things,” Ms. Rynders said. “But when my sister was sick, I couldn’t do anything to fix her. The doctors didn’t even know what was going on.”
When Ms. Rynders’ sister woke from the coma, she couldn’t speak. The only comfort Ms. Rynders could provide was her presence and the ability to put a smile on her sister’s face. So, Ms. Rynders did what came naturally ...
She danced.
In that tiny hospital room, she blasted her sister’s favorite song — “Party in the U.S.A.” by Miley Cyrus — and danced around the room, doing anything she could to make her sister laugh.
And this patient who could not form words found her voice.
“She’d holler so deeply, it almost sounded like she was crying,” Ms. Rynders remembered. “The depths of her grief and the depths of her joy coming out simultaneously. It was really amazing and so healing for both of us.”
Do You Know How Powerful Dancing Really Is?
Ms. Rynders is far from the only healthcare professional who’s discovered the healing power of dance. In recent years, doctors and nurses across the country, from Los Angeles, California, to Atlanta, Georgia; from TikTok’s “Dancing Nurse,” Cindy Jones, to Max Chiu, Nebraska’s breakdancing oncologist, have demonstrated that finding new ways to move your body isn’t just good advice for patients but could be exactly what healthcare providers need to stay mentally and physically healthy.
It comes at a time when the field faces a “mental health crisis,” according to a 2023 report from the Centers for Disease Control and Prevention. Medscape Physician Burnout & Depression Report 2024 found current rates of 49% for burnout and 20% for depression.
And medical professionals are often hesitant about seeking help. Nearly 40% of physicians reported reluctance to seek out mental health treatment over fears of professional repercussions, according to 2024 recommendations by the Mayo Clinic.
The solution? It just might be dancing.
There’s ample evidence. A 2024 study from the University of Sydney, Australia, found that dancing offers more psychological and cognitive benefits — helping with everything from depression to motivation to emotional well-being — than any other type of exercise.
Another study, published in February by
Structured dance, where you learn specific movements, can offer a huge boost to mental health, according to a 2024 University of Sydney study. But so does unchoreographed dancing, where you’re basically just letting your limbs do their own thing. A 2021 study, published in Complementary Therapies in Clinical Practice, found that 95% of dancers who just moved their bodies, regardless of how it looked to the outside world, still had huge benefits with depression, anxiety, and trauma.

Deborah Cohan, MD, 55, an obstetrician at Zuckerberg San Francisco General Hospital and Trauma Center, San Francisco, California, discovered firsthand the power of dance back in 2013. After finding a lump in her breast during a self-exam, Dr. Cohan feared the worst. Days later, her radiologist confirmed she had invasive ductal carcinoma.
“It was a complete shock,” Dr. Cohan remembered. “I took care of myself. I ate right. I had no obvious risk factors. I did work the night shift, and there’s actually an increased risk for breast cancer among ob.gyn. workers who do night shift work. But still, it took me completely by surprise. My kids were 5 and 8 at the time, and I was terrified that they’d grow up without a mom.”
So, Dr. Cohan turned to the only thing that gave her comfort — dance class. Dancing had been an escape for Dr. Cohan since she took her first ballet class at age 3. So, she skipped work and went to her weekly Soul Motion dance class, where she found herself doing the exact opposite of escaping. She embraced her fears.
“I visualized death as a dance partner,” Dr. Cohan said. “I felt a freedom come over my body. It didn’t make sense to me at the time, but it was almost joyful. Not that I was accepting death or anticipating death, but just that I acknowledged its presence. There’s so much pressure among people with cancer to be positive. [But] that’s something that needs to come from within a person, not from outside. Nobody can dictate how someone should be feeling. And as I danced, I was genuinely feeling joy even as I recognized my own fears and didn’t turn away from them. I was experiencing all the emotions at once. It was such a relief to realize this wasn’t all going to be about sadness.”
The experience was so healing for Dr. Cohan that she decided to see if she could bring those same feelings into her bilateral mastectomy. When meeting with her surgical team, Dr. Cohan made an unorthodox request: Could her pre-op include a dance party?
“I asked the anesthesiologist in the pre-op appointment if I could dance, and he said yes,” she remembered, laughing. “And then I checked with the surgeon, and he said yes. And then I asked the perioperative nurse, and he said yes, ‘but only if you don’t make me dance, too’. So somehow it all came together.”
Dr. Cohan decided on the Beyoncé song “Get Me Bodied,” which she says resonated with her because “it’s all about being in your body and being your full self. I was like, that is exactly how I want to show up in the operating room.” The moment the music kicked in and Dr. Cohan broke into dance, all of her stress melted away.
“Even though I’d been given permission to dance, I never expected anybody else to join in,” Dr. Cohan said. But that’s exactly what they did. A friend took a video, which shows Dr. Cohan in a hospital gown and bouffant cap, dancing alongside her surgical and anesthesia teams, all of whom are dressed in scrubs, at Mount Zion Hospital in San Francisco, California.
“It’s weird to say, especially about a mastectomy,” Dr. Cohan said, “but it was one of the most joyful moments of my life.”
The video’s been viewed 8.4 million times and is so inspirational — we dare you to watch it and not want to jump out of your chair to dance — that soon others were following Dr. Cohan’s lead.
- Sixteen-year-old Amari Hall danced to celebrate her successful heart transplant.
- Ana-Alecia Ayala, a 32-year-old uterine cancer survivor, danced along to “Juju on That Beat” to make chemotherapy more tolerable.
- Doreta Norris, a patient with breast cancer, chose “Gangnam Style” to serenade her into surgery.
Bringing Dance to Other Medical Pros
Ms. Rynders realized the true power of dance years before her sister’s illness, when her mother died of cancer. “I’ve always considered myself to be very resilient as a human, but I couldn’t bounce back after my mom died,” she said. “I was nursing full time in the emergency room, and I was sad all the time. And then one day I realized, you know what brings me joy? It’s always been dance.”
She went back to school to get her Master of Fine Arts in Dance from the University of Colorado at Boulder, which she believes helped her heal. “I was actually able to grieve instead of just pretending I was okay,” she said.
Inspired by these experiences, Ms. Rynders founded The Clinic in 2017, a company that provides dance workshops for healthcare professionals struggling with burnout and secondary traumatic stress.
“I see these nurses running down hospital hallways, covered in blood from patients whose lives are literally hanging on a thread,” she said. “They’re dealing with so much stress and grief and hardship. And then to see them with us, playing and laughing — those deep belly laughs that you haven’t done since you were a kid, the deep laughing that comes from deep in your soul. It can be transformational, for them and for you.”
Ms. Rynders remembers one especially healing workshop in which the participants pretended to be astronauts in deep space, using zero gravity to inform their movements. After the exercise, a veteran hospital nurse took Ms. Rynders aside to thank her, mentioning that she was still dealing with grief for her late son, who had died from suicide years earlier.
“She had a lot of guilt around it,” Ms. Rynders remembered. “And she said to me, ‘When I went to space, I felt closer to him.’ It was just this silly little game, but it gave her this lightness that she hadn’t felt in years. She was able to be free and laugh and play and feel close to her son again.”
Good Medicine
Dr. Cohan, who today is cancer free, said her experience made her completely rethink her relationship with patients. She has danced with more than a few of them, though she’s careful never to force it on them. “I never want to project my idea of joy onto others,” she said. “But more than anything, it’s changed my thinking on what it means to take ownership as a patient.”
The one thing Dr. Cohan never wanted as a patient, and the thing she never wants for her own patients, is the loss of agency. “When I danced, I didn’t feel like I was just handing over my body and begrudgingly accepting what was about to happen to me,” she said. “I was taking ownership around my decision, and I felt connected, really connected, to my surgical team.”
As a patient, Dr. Cohan experienced what she calls the “regimented” atmosphere of medicine. “You’re told where to go, what to do, and you have no control over any of it,” recalled Dr. Cohan, who’s now semiretired and runs retreats for women with breast cancer. “But by bringing in dance, it felt really radical that my healthcare team was doing my thing, not the other way around.”
(Re)Learning to Move More Consciously
Healthcare providers need these moments of escape just as much as patients living with disease. The difference is, as Ms. Rynders points out, those in the medical field aren’t always as aware of their emotional distress. “I think if you ask a nurse, ‘How can I help you? What do you need?’ They’re usually like, ‘I don’t know. I don’t even know what I need,’ ” Ms. Rynders said. “Even if they did know what they needed, I think it’s hard to ask for it and even harder to receive it.”
At Ms. Rynders’ workshops, not everybody is comfortable dancing, of course. So, new participants are always given the option just to witness, to be in the room and watch what happens. “But I also really encourage people to take advantage of this opportunity to do something different and disrupt the way we live on a daily basis,” Ms. Rynders said. “Let your brain try something new and be courageous. We’ve only had a few people who sat on the sidelines the whole time.”
It’s not always just about feelings, Dr. Cohan added, but physical relaxation. “Sometimes it’s just about remembering how to move consciously. When I was having surgery, I didn’t just dance to relax myself. I wanted my entire surgical team to be relaxed.”
For Ms. Rynders, every time she dances with her patients, or with fellow healthcare workers, she’s reminded of her sister and the comfort she was able to give her when no amount of medicine would make things better.
“We don’t always need to be fixed by things,” she said. “Sometimes we just need to be present with one another and be with each other. And sometimes, the best way to do that is by dancing till the tears roll down your cheeks.”

In 2012, Tara Rynders’ sister was diagnosed with acute disseminated encephalomyelitis. For Ms. Rynders, a registered nurse in Denver, Colorado, the news was devastating.
“She was this beautiful 26-year-old woman, strong and healthy, and within 12 hours, she went into a coma and couldn’t move or speak,” Ms. Rynders remembered. She flew to her sister in Reno, Nevada, and moved into her intensive care unit room. The helplessness she felt wasn’t just as a sister, but as a healthcare provider.
“As a nurse, we love to fix things,” Ms. Rynders said. “But when my sister was sick, I couldn’t do anything to fix her. The doctors didn’t even know what was going on.”
When Ms. Rynders’ sister woke from the coma, she couldn’t speak. The only comfort Ms. Rynders could provide was her presence and the ability to put a smile on her sister’s face. So, Ms. Rynders did what came naturally ...
She danced.
In that tiny hospital room, she blasted her sister’s favorite song — “Party in the U.S.A.” by Miley Cyrus — and danced around the room, doing anything she could to make her sister laugh.
And this patient who could not form words found her voice.
“She’d holler so deeply, it almost sounded like she was crying,” Ms. Rynders remembered. “The depths of her grief and the depths of her joy coming out simultaneously. It was really amazing and so healing for both of us.”
Do You Know How Powerful Dancing Really Is?
Ms. Rynders is far from the only healthcare professional who’s discovered the healing power of dance. In recent years, doctors and nurses across the country, from Los Angeles, California, to Atlanta, Georgia; from TikTok’s “Dancing Nurse,” Cindy Jones, to Max Chiu, Nebraska’s breakdancing oncologist, have demonstrated that finding new ways to move your body isn’t just good advice for patients but could be exactly what healthcare providers need to stay mentally and physically healthy.
It comes at a time when the field faces a “mental health crisis,” according to a 2023 report from the Centers for Disease Control and Prevention. Medscape Physician Burnout & Depression Report 2024 found current rates of 49% for burnout and 20% for depression.
And medical professionals are often hesitant about seeking help. Nearly 40% of physicians reported reluctance to seek out mental health treatment over fears of professional repercussions, according to 2024 recommendations by the Mayo Clinic.
The solution? It just might be dancing.
There’s ample evidence. A 2024 study from the University of Sydney, Australia, found that dancing offers more psychological and cognitive benefits — helping with everything from depression to motivation to emotional well-being — than any other type of exercise.

Structured dance, where you learn specific movements, can offer a huge boost to mental health, according to a 2024 University of Sydney study. But so does unchoreographed dancing, where you’re basically just letting your limbs do their own thing.

Modified Sleep Apnea Index Score Associated With CV Risk
Use of a modified sleep apnea index can identify cardiovascular risk factors in adults with moderate to severe obstructive sleep apnea (OSA), according to results from a new study presented at the American Academy of Otolaryngology–Head and Neck Surgery 2024 Annual Meeting.
, said Jennifer A. Goldfarb, MHS, a medical student at Thomas Jefferson University, Philadelphia, Pennsylvania, who presented the findings.
OSA has an association with many negative cardiovascular comorbidities; however, “the AHI provides only a single metric and does not provide a holistic assessment of the individual patient’s disease severity,” said senior author Colin T. Huntley, MD, also of Thomas Jefferson University.
“OSA is very complex, and having a robust system to assess the disease may be a better predictor of overall severity,” he told this news organization.
Previous research has shown a correlation between mSASI and mean arterial pressure and serum C-reactive protein in OSA patients, but the connection with cardiovascular risk factors has not been well studied, Ms. Goldfarb noted.
In the retrospective cohort study, Ms. Goldfarb and colleagues looked at mSASI scores from 260 CPAP-intolerant patients with OSA who underwent upper airway stimulation, maxillomandibular advancement, or expansion sphincter pharyngoplasty at a single sleep surgery clinic between 2014 and 2021. The mSASI uses a score of 1-3, with 3 as the highest level of OSA severity.
Cardiovascular risk factors were assessed at the patient’s initial evaluation by the sleep surgery team. They included coronary artery disease, type 2 diabetes, atrial fibrillation, congestive heart failure, hypertension, and cerebrovascular accident.
A total of 142 patients (55%) had an mSASI of 1; 91 (35%) had an mSASI of 2; and 27 (10%) had an mSASI of 3. At least one cardiovascular risk factor was present in 58%, 68%, and 63% of these groups, respectively (P = .3).
Stratifying participants by mSASI scores, the researchers found that patients with an mSASI of 2 or 3 were significantly more likely than those with an mSASI of 1 to have more cardiovascular risk factors on initial presentation, and were significantly more likely to be diagnosed with hypertension (P = .02 for both).
Using the AHI, however, patients with moderate to severe OSA (AHI > 15) had a similar number of cardiovascular risk factors as those with mild OSA (P > .05).
“A higher mSASI score, which represents worse disease, was associated with a higher Framingham risk score, which supported our hypothesis; however, the AHI was not found to be associated with an increased Framingham score,” Dr. Huntley told this news organization.
Takeaways and Next Steps
These results suggest that the AHI, while a good metric, might not be the best tool for assessment of overall disease severity, given the complexity of OSA, the impact of the disease on patient quality of life, and the risk for downstream cardiovascular disease, said Dr. Huntley.
The findings were limited by the retrospective design and use of data from a single center.
Population-level data are needed to identify variables that may be meaningful to create a future tool that provides the best picture of the individual patient’s disease, he added. Additional prospective data are also needed to assess the impact of the scoring system on long-term treatment outcomes.
“The current study is especially interesting as we are just beginning to understand the factors that predict cardiovascular risk for patients with obstructive sleep apnea,” Megan Durr, MD, of the University of California, San Francisco, said in an interview.
“For a long time, we primarily looked at the AHI and/or oxygen levels during sleep as risk factors, and we haven’t looked as much at other factors.” said Dr. Durr, who served as a moderator for the session in which the study was presented.
The current findings provide a more comprehensive look at cardiovascular risk; the inclusion of patient anatomy and symptoms add to the knowledge of this topic, and will lead to further work in this area, she added.
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Huntley disclosed receiving research support from Nyxoah and Inspire, and serving as a consultant for Nyxoah, Inspire, and Avivomed.

Use of a modified sleep apnea index can identify cardiovascular risk factors in adults with moderate to severe obstructive sleep apnea (OSA), according to results from a new study presented at the American Academy of Otolaryngology–Head and Neck Surgery 2024 Annual Meeting.
, said Jennifer A. Goldfarb, MHS, a medical student at Thomas Jefferson University, Philadelphia, Pennsylvania, who presented the findings.
OSA has an association with many negative cardiovascular comorbidities; however, “the AHI provides only a single metric and does not provide a holistic assessment of the individual patient’s disease severity,” said senior author Colin T. Huntley, MD, also of Thomas Jefferson University.
“OSA is very complex, and having a robust system to assess the disease may be a better predictor of overall severity,” he told this news organization.
Previous research has shown a correlation between mSASI and mean arterial pressure and serum C-reactive protein in OSA patients, but the connection with cardiovascular risk factors has not been well studied, Ms. Goldfarb noted.
In the retrospective cohort study, Ms. Goldfarb and colleagues looked at mSASI scores from 260 CPAP-intolerant patients with OSA who underwent upper airway stimulation, maxillomandibular advancement, or expansion sphincter pharyngoplasty at a single sleep surgery clinic between 2014 and 2021. The mSASI uses a score of 1-3, with 3 as the highest level of OSA severity.

Three Tips to Avoid Common Diagnostic Errors in Primary Care
Common complaints of abdominal pain, fever, shortness of breath, or rash can signal more serious disease that should be referred to specialty care or might be related to benign conditions.
Combine the vague nature of many patients’ descriptions and the pressure of short visits, and clinicians have a recipe for all manner of diagnostic error.
An estimated 5% of US adults who seek outpatient care each year experience a diagnostic error. Most Americans will eventually have this experience, according to a 2015 report from the National Academy of Medicine.
The most frequently missed diagnoses in primary care involve conditions such as pneumonia, decompensated heart failure, acute renal failure, cancer, urinary tract infection, and pyelonephritis.
“It’s not one or two or three types of diagnosis that are missed: We miss a lot of things, especially in primary care,” said Hardeep Singh, MD, MPH, a patient safety researcher at the Michael E. DeBakey VA Medical Center and the Baylor College of Medicine in Houston, Texas.
One of the most serious errors is to miss cancer, with failing to follow‐up on abnormal tests ranking consistently as one of the leading causes of malpractice claims. But most diagnostic errors do not lead to lawsuits, although they often result in missed and delayed opportunities for patients to get needed care.
In interviews with this news organization, experts who have studied the root causes of diagnostic error suggested primary care clinicians focus on several practices to avoid mistakes: Ask questions with humility and curiosity, use checklists, and brainstorm with patients the potential root cause of symptoms.
Humility and Curiosity
Clinicians should remain aware of the potential for errors and reach out for assistance when needed, keeping an open mind that common symptoms may, in rare cases, signal serious illness, Dr. Singh said.
Dr. Singh recommends continual review with what he calls “byte-sized” learning through digital tools such as the Human Diagnosis app and podcasts and webinars offered by Clinical Problem Solvers.
Continuing education activities such as classes for Maintenance of Certification (MOC) can help keep physicians up to date and alert for cases where seemingly common symptoms may turn out to be something serious, said Richard M. Wardrop, III, MD, PhD, an internal medicine physician at the Cleveland Clinic in Ohio, and chair of the internal medicine board at the American Board of Internal Medicine.
“I’ve been in practice for 20 years. I’m double board certified in peds and medicine, and I regularly teach students and residents and mentor other physicians, but the further I go in my career and in practice, the more humble I become,” Dr. Wardrop told this news organization.
He said he recently spent a few hours on MOC for pediatrics and found the review was helpful in his practice in medicine.
“If I find myself taking care of a patient in a newborn nursery anytime soon, I’m going to understand the new hyperbilirubinemia guidelines,” Dr. Wardrop said. “That takes time and energy, but when I was done with the questions for this quarter, I felt good about myself.”
Checking It Twice
Clinicians should incorporate checklists into daily practice. Reviewing these with patients can not only help rule out an illness but also serve as a nonconfrontational method to inquire about issues patients may find uncomfortable, said John Ely, MD, MSPH, professor emeritus of family medicine at the University of Iowa Carver College of Medicine in Iowa City.
Clinicians could benefit from the approach used in aviation, where checklists are a required and routine part of a pilot’s job, Dr. Ely said.
Although clinicians may assume patients expect them to work from memory and knowledge without this aide, many will see using a checklist as a sign of providing thorough care, he said.
Checklists can also open a pathway for discussions about potentially difficult or touchy issues in short visits. For example, a patient might feel defensive if a clinician asks about depression during a visit for abdominal pain. But incorporating a question in a checklist allows for a different framing of the question.
“A clinician could say ‘I didn’t say you were depressed because of your abdominal pain, I brought it up because it’s on the list,’” Dr. Ely said. The checklist is “a very easy way to bring up those things.”
Dr. Ely said he has cared for a few patients who sought help for abdominal pain that turned out to be linked to sexual abuse in their past. Dr. Ely used a checklist with these patients to review possible causes for their illness. He recalled one of these patients who had suffered sexual abuse and had depression, neither of which was readily apparent.
“There was nothing about her affect that appeared to be depressed, and she had seen multiple physicians unable to make a diagnosis,” Dr. Ely said. “She had worked up for multiple other diseases and this had never come up before.”
Cooperation
“Coproduction” is how Kathryn McDonald, PhD, describes an ideal path to getting an accurate diagnosis. The intent is for clinicians to enlist patients in helping them in finding the root cause of symptoms.
“It’s bringing the patient into knowing that they are in a partnership to coproduce, knowing that there is a process going on,” said Dr. McDonald, who is codirector of the Armstrong Institute Center for Diagnostic Excellence at Johns Hopkins University in Baltimore, Maryland.
In many cases, patients seek reassurance for ruling out a suspected condition, which the physician can sometimes provide. In others, clinicians may not be able to offer a concrete diagnosis.
“There are times when uncertainty is more pervasive and I will ask patients, ‘Let’s brainstorm this together,’” Dr. Wardrop said.

Heightened Amygdala Activity Tied to Postpartum Depression
MILAN, ITALY — Pregnant women with heightened amygdala activity have a reduced capacity to regulate emotions and report more symptoms of depression than those with lower activity in this brain region, a new imaging study suggested.
If validated, these findings could pave the way for identifying women at higher risk for postpartum depression, said lead researcher Franziska Weinmar, MSc, from the University of Tübingen in Germany.
The study was presented at the 37th European College of Neuropsychopharmacology Congress.
Differences in Brain Activity
During pregnancy and the peripartum period, rising hormone levels create a “psychoneuroendocrinological window of vulnerability” for mental health in which 80% of women can develop transitory “baby blues,” and about one in seven develop more serious postpartum depression, Ms. Weinmar told this news organization.
The study included 47 women — 15 pregnant women and 32 nonpregnant controls. The nonpregnant women had normal menstrual cycles; 16 were in the early follicular phase with low estradiol levels (231.7 pmol/L), and 16 had high estradiol levels (516.6 pmol/L) after administration of estradiol.
To examine brain activity, participants were asked to view negative emotional images while undergoing functional MRI. They were then asked to use cognitive reappraisal to regulate their emotional response to the images.
The findings showed that both pregnant and nonpregnant women were equally successful at emotional regulation, but this process involved different brain activity in pregnant vs their nonpregnant counterpart.
All women had increased left middle frontal gyrus activity when regulating their emotions, but there was a difference in the amygdala between the pregnancy group and controls, Ms. Weinmar noted.
This suggests that pregnant women may have to exert more neural effort in emotional regulation, she said. “And pregnant women with higher amygdala activity were less able to regulate their emotions successfully compared to those with less amygdala activity.”
Linear regression analyses were performed to assess the relation of brain activity during down-regulation, regulation success, and self-reported depression scores, and this showed that higher amygdala activity was also associated with higher depression scores.
“We need to be cautious in interpreting this,” said Ms. Weinmar. “This is a small sample, and we are the first to undertake this work.”
Nonetheless, she said that if the findings are confirmed by larger studies, pregnant women could be assessed “in the waiting room” using existing questionnaires that evaluate emotional regulation.
If a woman has difficulties with emotion regulation, “there are adaptive strategies, like cognitive reappraisal that a counseling psychotherapist can help with,” said Ms. Weinmar.
“I could also imagine group sessions, for example, or online courses,” she said, adding that obstetricians could also be trained to identify these women.
Commenting on the findings in a press release, Susana Carmona, PhD, from Gregorio Marañón Hospital in Madrid, Spain, said research like this is crucial for gaining insight into one of the most intense physiological processes a human can undergo: pregnancy. It’s remarkable how much remains unknown.
“Recently, the FDA [Food and Drug Administration] approved the first treatment for postpartum depression. However, we still have a long way to go in characterizing what happens in the brain during pregnancy, identifying biomarkers that can indicate the risk of developing perinatal mental disorders, and designing strategies to prevent mother and infant suffering during the delicate and critical peripartum period,” Dr. Carmona added.
The study was supported by the Center for Integrative Neuroscience in Tübingen, Germany, and the International Research Training Group “Women’s Mental Health Across the Reproductive Years” (IRTG 2804). Ms. Weinmar and Dr. Carmona reported no relevant disclosures.

During pregnancy and the peripartum period, rising hormone levels create a “psychoneuroendocrinological window of vulnerability” for mental health in which 80% of women can develop transitory “baby blues,” and about one in seven develop more serious postpartum depression, Ms. Weinmar told this news organization.
The study included 47 women — 15 pregnant women and 32 nonpregnant controls. The nonpregnant women had normal menstrual cycles; 16 were in the early follicular phase with low estradiol levels (231.7 pmol/L), and 16 had high estradiol levels (516.6 pmol/L) after administration of estradiol.
To examine brain activity, participants were asked to view negative emotional images while undergoing functional MRI. They were then asked to use cognitive reappraisal to regulate their emotional response to the images.
The findings showed that both pregnant and nonpregnant women were equally successful at emotional regulation, but this process involved different brain activity in pregnant vs their nonpregnant counterpart.
All women had increased left middle frontal gyrus activity when regulating their emotions, but there was a difference in the amygdala between the pregnancy group and controls, Ms. Weinmar noted.
This suggests that pregnant women may have to exert more neural effort in emotional regulation, she said. “And pregnant women with higher amygdala activity were less able to regulate their emotions successfully compared to those with less amygdala activity.”
Linear regression analyses were performed to assess the relation of brain activity during down-regulation, regulation success, and self-reported depression scores, and this showed that higher amygdala activity was also associated with higher depression scores.
“We need to be cautious in interpreting this,” said Ms. Weinmar. “This is a small sample, and we are the first to undertake this work.”
Nonetheless, she said that if the findings are confirmed by larger studies, pregnant women could be assessed “in the waiting room” using existing questionnaires that evaluate emotional regulation.
If a woman has difficulties with emotion regulation, “there are adaptive strategies, like cognitive reappraisal that a counseling psychotherapist can help with,” said Ms. Weinmar.
“I could also imagine group sessions, for example, or online courses,” she said, adding that obstetricians could also be trained to identify these women.
Commenting on the findings in a press release, Susana Carmona, PhD, from Gregorio Marañón Hospital in Madrid, Spain, said research like this is crucial for gaining insight into one of the most intense physiological processes a human can undergo: pregnancy. It’s remarkable how much remains unknown.
“Recently, the FDA [Food and Drug Administration] approved the first treatment for postpartum depression. However, we still have a long way to go in characterizing what happens in the brain during pregnancy, identifying biomarkers that can indicate the risk of developing perinatal mental disorders, and designing strategies to prevent mother and infant suffering during the delicate and critical peripartum period,” Dr. Carmona added.
The study was supported by the Center for Integrative Neuroscience in Tübingen, Germany, and the International Research Training Group “Women’s Mental Health Across the Reproductive Years” (IRTG 2804). Ms. Weinmar and Dr. Carmona reported no relevant disclosures.
