At Last, a Nasal Epinephrine Spray
This summer, the US Food and Drug Administration (FDA) fast-tracked approval of the first-in-its-class nasal epinephrine (neffy). It’s a very welcome addition to our anaphylaxis treatment armamentarium. In healthy volunteers, neffy achieved similar serum epinephrine levels, rises in blood pressure, and pulse compared with IM epinephrine.
The Need for Neffy
It was just a few days ago that I saw a new patient with fire ant anaphylaxis. The last time he tried to use an injectable epinephrine pen, he made two mistakes. First, he placed the wrong end against his thigh, and when it did not inject, he depressed it with his thumb — in other words, he injected his thumb with epinephrine. Of course, that cannot happen with neffy.
I recall a few years ago, a child experienced anaphylaxis but the parent was hesitant to administer the EAI (epinephrine autoinjector). The parent drove to the emergency room but was delayed by traffic, and by the time they reached the ER, the patient had suffered a respiratory arrest and passed away.
Patients are not the only ones who are hesitant to administer epinephrine. Some clinicians do not treat anaphylaxis appropriately. As an allergist, I see patients after-the-fact for diagnosis and management. Patients often tell me of systemic allergic reactions treated with IV antihistamines/corticosteroids and even sometimes with nebulized beta agonists, but not epinephrine.
My opinion is that it’s not just needle phobia. As I mentioned, in my Medscape commentary “Injectable Epinephrine: An Epidemic of Misuse,” I believe it’s due to a misunderstanding of the guidelines and a sense that epinephrine is a potent medication to be used sparingly. Clinicians and patients must understand that epinephrine is a naturally occurring hormone and administration leads to serum levels seen under other natural circumstances (eg, stress — the fight-or-flight surge). The aforementioned article also includes a patient handout, “Don’t Fear Epinephrine,” which I encourage you to read and distribute.
The potential benefits of neffy are clear:
- It should overcome fear of injection ergo being more likely to be used, and used earlier, by both patient/family member and clinicians.
- It’s easier to carry than many larger devices (though not the AUVI-Q).
- It cannot be injected incorrectly.
- Expiration is 8 months longer than the EAI.
- There are no pharmacist substitutions (as there is no equivalent device).
Potential Problems With Neffy and Some Suggested Solutions
As promising and beneficial as it is, I wonder about a few training issues. In the office, patients can be trained with a (reusable) injectable epinephrine trainer but not with a nasal spray device trainer in the office (an important alternative is a small model of a nose in the office for patient education). A training device should also be included in the neffy prescription, as with the EAI.
Neffy and Patients With Nasal Polyps or Nasal Surgery
It’s more complicated than that neffy cannot be used with patients who have had nasal polyps or nasal surgery. It’s really about how much healthy nasal mucosa is required for absorption. Nasal surgery may be simple or complex. Nasal polyps may be obstructive or resolved with nasal steroid or biologic therapy. Nasal polyps affect 2% of the population, but 35% of pediatric food allergy (FA) patients develop allergic rhinitis (AR), and these AR symptoms present even when not triggered by FA. AR is present at baseline in patients with FA. How does this influence neffy absorption? For FA patients who have anaphylactic reactions with severe nasal reactions, neffy absorption could be further compromised, something that has not been studied.
Insurance Coverage
As we don’t yet know the comparative efficacy of neffy in anaphylactic episodes, it’s likely that patients, especially with more severe food sensitivities, will be prescribed both the nasal and IM devices. The question remains whether insurance will cover both.
In “mild cases,” I suspect that doctors might be more inclined to prescribe neffy.
Conclusion
Delay in epinephrine use is frequent despite the clear indication during anaphylactic episodes, which in turn increases risk for mortality. Neffy will probably save many lives.

4 Simple Hacks to Get Paid for Lifestyle Medicine
This transcript has been edited for clarity.
As primary care doctors, lifestyle medicine is supposed to be a pillar of our practice. Per the evidence, lifestyle medicine can prevent up to 80% of chronic disease. It’s a real irony, then, that it’s the thing we’re least likely to be paid to do.
Thankfully, though, there are a few hacks to help you keep your patients healthy and yourself financially healthy at the same time.
No. 1: Be as accurate in your coding as possible. We all know working on things like sleep, exercise, and diet with patients takes time, so bill for it. With time-based billing, in particular, you can account for both the time spent in face-to-face encounters and the time spent afterward on documentation and care coordination. Make sure to capture that.
No. 2: Try group visits on for size. Group visit models are great for lifestyle medicine. They give you the flexibility to include longer conversations and deeper lessons on a range of subjects while still getting paid for what you do. Want to host a cooking class? Group visit. Want to bring in a personal trainer or hold a dance class or exercise dance class? Group visit. Meditation, yoga, or even a sleep hygiene class? Group visit.
While there are a few tricks to getting paid for group visits, they’re the same things, such as documenting time and the various parts of the visit, that are key to getting paid for regular visits. They have the bonus of fighting burnout and making your own practice more meaningful as well.
No. 3: Think about joining a value-based care arrangement. While only accounting for 10% of the market right now, value-based care (VBC) is growing rapidly, and it’s easy to see why. By trading quality for the hamster wheel of billing widgets, physicians are freed up to think more about how best to take care of patients, including incorporating more lifestyle medicine. Some VBC models even have their own electronic medical records, freeing you from outdated structures when it comes to documenting patient visits.
No. 4: direct primary care. Direct primary care cuts out the middlemen of payers, letting patients pay physician practices directly for their own care. Like VBC, it opens up possibilities for practicing better medicine, including lifestyle medicine. In addition, it’s often very affordable, with a family of four often paying around $80 a month for a membership for the entire family. It’s a win-win for the doctor and the patient.
Lifestyle medicine is a great way to improve both your patients’ and your own well-being. With a few flexes, it can improve your wallet’s well-being, too.
Tamaan K. Osbourne-Roberts, President/CEO, Happiness by the Numbers, Denver, Colorado, has disclosed no relevant financial relationships.

Nutrition and Medical Education
How comfortable are you giving nutritional advice to your patients? When you offer it are you basing your advice on something you learned during medical school or your training? Was it included in a course devoted to nutrition? Did you learn it later as part of continuing medical education course (CME)? Or was it just something you just picked up from your experience seeing patients (osmosis)? It is very unlikely that a significant portion, or any part for that matter, of your medical training was devoted to nutrition. It certainly wasn’t during my training.
I recently read an interview with Emily M. Broad Leib, JD, faculty director of the Harvard School Center for Health Law and Policy Innovation, Cambridge, Massachusetts, who would like to correct that deficiency. She feels doctors need to know more about food and that acquiring that knowledge should be a significant component of their formal training.
In the interview, Leib said that “roughly 86% of physicians report they do not feel adequately trained to answer basic questions on diet or nutrition.” She also notes that while “72% of entering medical students report they believe food is important to health” less than 50% retained this belief after graduation.
Leib and associates feel they have recently reached a milestone in their efforts to include nutrition in the mainstream of medical education this fall by publishing a paper that demonstrates “consensus on doctor-approved nutritional standard for medical schools and residency programs.”
36 Recommended Competencies
Curious about what these nutrition experts chose to include in medical training, I decided to drill down into the list of 36 consensus-driven competencies they had agreed upon.
It was an interesting voyage into a forest of redundancies, many of which can be boiled down to having the student demonstrate that he/she understands that what we eat is important to our health and that there is a complex web of relationships connecting our society to the food consume.
Some of the recommended competencies I found make perfect sense. For example the student/trainee should be able to take a diet and food history and be able to interpret lab values and anthropometric measurements and be able to discuss the patient’s weight and diet with sensitivity while keeping in mind his/her own biases about food.
Some other recommendations are more problematic, for example, “performs a comprehensive nutrition-focused physical examination” or “demonstrates knowledge of how to create culinary nutrition SMART [Specific, Measurable, Achievable, Relevant, and Time-Bound] goals for personal use and for patient care” or “provides brief counseling interventions to help patients decrease visceral adiposity or reduce the risk of metabolic syndrome.” Including competencies like these demonstrates a lack of understanding of the time restraints and realities of a primary care physician’s life and training.
Instead of simply reinforcing the prospective physician’s preexisting assumption that food and health are entwined and discussing when and how to consult a nutrition expert, these 36 competencies seem to be an attempt to create fast-tracked part-time dietitians and nutrition advocates out of medical students and trainees who already believe that nutrition is important for health but also have a very full plate of clinical responsibilities ahead of them.
The study that Leib quotes — that 72% of medical students believed food was important in health while after graduation only 50% of agreed — doesn’t necessarily mean that professors are preaching that food was unimportant. It is more likely by the end of medical school the students have seen that food must share the spotlight with numerous other factors that influence their patients’ health.
‘A More Appropriate Focus’
In my experience, diet and lifestyle counseling done well is extremely time consuming and best done by people for whom that is their specialty. A more appropriate focus for a list of nutritional competencies for physicians in training would be for the student to achieve an understanding of when and how to consult a dietitian and then how to support and evaluate the dietitian’s recommendations to the patient.
Finally, I don’t think we can ignore a serious public relations problem that hangs like a cloud over the nutrition advocacy community. It is the same one that casts a shadow on the medical community as well. It is a common perception among the lay public that nutritionists (and physicians) are always changing their recommendations when it comes to food. What is believable? Just think about eggs, red wine, or introducing peanuts to infants, to name just a few. And what about the food pyramids that seem to have been rebuilt every several years? The problem is compounded when some “credentialed” nutritionists and physicians continue to make dietary pronouncements with only a shred of evidence or poorly documented anecdotal observations.
The first of the 36 competencies I reviewed reads: “Provide evidence-based, culturally sensitive nutrition and food recommendations for the prevention and treatment of disease.” When it comes to nutrition the “evidence” can be tough to come by. The natural experiments in which individuals and populations had extremely limited access to a certain nutrients (eg, scurvy) don’t occur very often. Animal studies don’t always extrapolate to humans. And, observational studies concerning diet often have co-factors that are difficult to control and must run over time courses that can tax even the most patient researchers.
I certainly applaud Leib and associates for promoting their primary goal of including more about of the relationship between food and health in the medical school and trainee curriculum. But I must voice a caution to be careful to keep it truly evidence-based and in a format that acknowledges the realities of the life and education of a primary care provider.
The best nutritional advice I ever received in my training was from an older pediatric professor who suggested that a healthy diet consisted of everything in moderation.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

The study that Leib quotes — that 72% of medical students believed food was important in health while after graduation only 50% of agreed — doesn’t necessarily mean that professors are preaching that food was unimportant. It is more likely by the end of medical school the students have seen that food must share the spotlight with numerous other factors that influence their patients’ health.
‘A More Appropriate Focus’
In my experience, diet and lifestyle counseling done well is extremely time consuming and best done by people for whom that is their specialty. A more appropriate focus for a list of nutritional competencies for physicians in training would be for the student to achieve an understanding of when and how to consult a dietitian and then how to support and evaluate the dietitian’s recommendations to the patient.
Finally, I don’t think we can ignore a serious public relations problem that hangs like a cloud over the nutrition advocacy community. It is the same one that casts a shadow on the medical community as well. It is a common perception among the lay public that nutritionists (and physicians) are always changing their recommendations when it comes to food. What is believable? Just think about eggs, red wine, or introducing peanuts to infants, to name just a few. And what about the food pyramids that seem to have been rebuilt every several years? The problem is compounded when some “credentialed” nutritionists and physicians continue to make dietary pronouncements with only a shred of evidence or poorly documented anecdotal observations.
The first of the 36 competencies I reviewed reads: “Provide evidence-based, culturally sensitive nutrition and food recommendations for the prevention and treatment of disease.” When it comes to nutrition the “evidence” can be tough to come by. The natural experiments in which individuals and populations had extremely limited access to a certain nutrients (eg, scurvy) don’t occur very often. Animal studies don’t always extrapolate to humans. And, observational studies concerning diet often have co-factors that are difficult to control and must run over time courses that can tax even the most patient researchers.
I certainly applaud Leib and associates for promoting their primary goal of including more about of the relationship between food and health in the medical school and trainee curriculum. But I must voice a caution to be careful to keep it truly evidence-based and in a format that acknowledges the realities of the life and education of a primary care provider.
The best nutritional advice I ever received in my training was from an older pediatric professor who suggested that a healthy diet consisted of everything in moderation.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Sea Buckthorn
A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7
This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11
Key Constituents
Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6
Polysaccharides
In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1
Proanthocyanidins and Anti-Aging
In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13
A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9
Acne and Barrier Functions
The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16
Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity
Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17
In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.
More recently, Gęgotek and colleagues found that sea buckthorn seed oil prevented redox balance and lipid metabolism disturbances in skin fibroblasts and keratinocytes caused by UVA or UVB. They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19
In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20
Burns and Wound Healing
In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3
A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21
Conclusion
Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.

In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20
Burns and Wound Healing
In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3
A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21
Conclusion
Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.

America’s PCPs: Take a Bow
Hi, everyone. I’m Dr. Kenny Lin. I am a family physician and associate director of the Lancaster General Hospital Family Medicine Residency, and I blog at Common Sense Family Doctor.
For the past 4 years, primary care clinicians have labored under a seemingly endless onslaught of bad news. A recent report estimated that there were over 1.3 million excess deaths in the United States from March 2020 to May 2023, including nearly half a million Americans younger than age 65. Social isolation and an ailing economy accelerated preexisting rises in drug overdoses and obesity, while teenage vaping threatened to hook a new generation on tobacco products even as adult smoking plummeted. Meanwhile, more than half of the nation’s physicians now report feelings of burnout, pay for family doctors appears to be stagnating, and our interactions with an increasing number of patients are fraught with suspicions about the value of vaccines— not just against COVID-19 but against flu and other viruses, too — and the medical system as a whole, doctors included.
Now, for the good news.
A year and a half since the end of the pandemic emergency, we are seeing gains on several fronts, and physicians deserve much of the credit. Preliminary data from the Centers for Disease Control and Prevention show that 10,000 fewer people died from drug overdoses than in the previous year. Although multiple factors contributed to this change, the elimination of the X-waiver, which had previously been required for physicians to prescribe buprenorphine for opioid use disorder, in January 2023 has improved access to medications for addiction treatment. In addition, the expansion of state requirements to check prescription drug monitoring programs when opioids or benzodiazepines are prescribed, and to prescribe naloxone to patients taking more than a certain number of morphine milligram equivalents per day, has probably reduced the harms of hazardous drug use.
On the obesity front, recent data from the National Health and Nutrition Examination Survey found that the prevalence of obesity in adults fell for the first time in more than a decade, from 41.9% to 40.3%. To be sure, obesity remains far too common, and this finding could be the result of statistical chance rather than representing a true decline. But the widespread prescribing of GLP-1 receptor agonists by primary care physicians, in particular, could have played a role in the encouraging trend.
Although more research is needed to prove causality, one analysis suggests that these drugs could easily have lowered the body mass index (BMI) of more than enough patients to account for the observed decline. What’s more, the rise in prevalence of BMIs above 40 (from 7.7% to 9.7%) could be explained by the mortality benefit of the drugs: More people remained in this severe obesity category because they didn’t die from complications of their weight. Whether future studies support keeping people on GLP-1s for life or eventually “off-ramping” them to other weight control strategies, family physicians are well positioned to help.
Finally, with little fanfare, the youth smoking rate has fallen precipitously. In 2023, 1.9% of high school students and 1.1% of middle-schoolers reported smoking cigarettes in the past 30 days. And they didn’t simply swap one form of nicotine delivery device for another. The 30-day prevalence of vaping among high school students fell from 27.5% in 2019 to 7.8% this year. Changing social norms and stricter federal regulation of tobacco products are probably more responsible for this positive trend than medical care, though the US Preventive Services Task Force recommends education or brief counseling to prevent initiation of tobacco use among school-aged children and adolescents. Should tobacco use in youth remain at these historically low levels, millions of premature deaths from lung cancer and heart disease will have been prevented.
America’s doctors have earned the right to take a bow. We have much more work to do, but our efforts are making a meaningful difference in three seemingly intractable health problems.

On Second Thought: Aspirin for Primary Prevention — What We Really Know
This transcript has been edited for clarity.
Our recommendations vis-à-vis aspirin have evolved at a dizzying pace. The young’uns watching us right now don’t know what things were like in the 1980s. The Reagan era was a wild, heady time where nuclear war was imminent and we didn’t prescribe aspirin to patients.
That only started in 1988, which was a banner year in human history. Not because a number of doves were incinerated by the lighting of the Olympic torch at the Seoul Olympics — look it up if you don’t know what I’m talking about — but because 1988 saw the publication of the ISIS-2 trial, which first showed a mortality benefit to prescribing aspirin post–myocardial infarction (MI).
Giving patients aspirin during or after a heart attack is not controversial. It’s one of the few things in this business that isn’t, but that’s secondary prevention — treating somebody after they develop a disease. Primary prevention, treating them before they have their incident event, is a very different ballgame. Here, things are messy.
For one thing, the doses used have been very inconsistent. We should point out that the reason for 81 mg of aspirin is very arbitrary and is rooted in the old apothecary system of weights and measurements. A standard dose of aspirin was 5 grains, where 20 grains made 1 scruple, 3 scruples made 1 dram, 8 drams made 1 oz, and 12 oz made 1 lb - because screw you, metric system. Therefore, 5 grains was 325 mg of aspirin, and 1 quarter of the standard dose became 81 mg if you rounded out the decimal.
People have tried all kinds of dosing structures with aspirin prophylaxis. The Physicians’ Health Study used a full-dose aspirin, 325 mg every 2 days, while the Hypertension Optimal Treatment (HOT) trial tested 75 mg daily and the Women’s Health Study tested 100 mg, but every other day.
Ironically, almost no one has studied 81 mg every day, which is weird if you think about it. The bigger problem here is not the variability of doses used, but the discrepancy when you look at older vs newer studies.
Older studies, like the Physicians’ Health Study, did show a benefit, at least in the subgroup of patients over age 50 years, which is probably where the “everybody over 50 should be taking an aspirin” idea comes from, at least as near as I can tell.
More recent studies, like the Women’s Health Study, ASPREE, or ASPIRE, didn’t show a benefit. I know what you’re thinking: Newer stuff is always better. That’s why you should never trust anybody over age 40 years. The context of primary prevention studies has changed. In the ‘80s and ‘90s, people smoked more and we didn’t have the same medications that we have today. We talked about all this in the beta-blocker video to explain why beta-blockers don’t seem to have a benefit post MI.
We have a similar issue here. The magnitude of the benefit with aspirin primary prevention has decreased because we’re all just healthier overall. So, yay! Progress! Here’s where the numbers matter. No one is saying that aspirin doesn’t help. It does.
If we look at the 2019 meta-analysis published in JAMA, there is a cardiovascular benefit. The numbers bear that out. I know you’re all here for the math, so here we go. Aspirin reduced the composite cardiovascular endpoint from 65.2 to 60.2 events per 10,000 patient-years; or to put it more meaningfully in absolute risk reduction terms, because that’s my jam, an absolute risk reduction of 0.41%, which means a number needed to treat of 241, which is okay-ish. It’s not super-great, but it may be justifiable for something that costs next to nothing.
The tradeoff is bleeding. Major bleeding increased from 16.4 to 23.1 bleeds per 10,000 patient-years, or an absolute risk increase of 0.47%, which is a number needed to harm of 210. That’s the problem. Aspirin does prevent heart disease. The benefit is small, for sure, but the real problem is that it’s outweighed by the risk of bleeding, so you’re not really coming out ahead.
The real tragedy here is that the public is locked into this idea of everyone over age 50 years should be taking an aspirin. Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine.
That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.
But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

The tradeoff is bleeding. Major bleeding increased from 16.4 to 23.1 bleeds per 10,000 patient-years, or an absolute risk increase of 0.47%, which is a number needed to harm of 210. That’s the problem. Aspirin does prevent heart disease. The benefit is small, for sure, but the real problem is that it’s outweighed by the risk of bleeding, so you’re not really coming out ahead.
The real tragedy here is that the public is locked into this idea of everyone over age 50 years should be taking an aspirin. Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine.
That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.
But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

Lifestyle Medicine Trends to Keep an Eye On
Our current healthcare system, which is a costly and unending cycle of merely managing chronic disease symptoms, is failing us. What we truly need is a patient-centered approach that restores health by addressing not just diagnoses but also the physical, emotional, and social needs of each individual. This is the essence of whole-person health, and transformation toward this model of care is already underway.
This shift underscores why clinicians like me support placing lifestyle medicine at the foundation of health and healthcare. Evidence-based lifestyle medicine — which applies interventions in nutrition, physical activity, restorative sleep, stress management, positive social connections, and avoidance of risky substances to prevent, treat, and when used intensively, even reverse lifestyle-related chronic disease — is a medical specialty equipped to successfully address patients’ whole-person health in an effective, high-value clinical care delivery model.
As this transformation continues, here are four key lifestyle medicine trends for 2025.
Lifestyle Medicine Becomes More Ingrained in Primary Care
The 2021 National Academies of Science, Engineering, and Medicine report, “Implementing High-Quality Primary Care” sounded the alarm about the state of primary care and outlined a comprehensive approach to transform it. Lifestyle medicine emerged as a solution as clinicians found innovative ways to integrate lifestyle behavior interventions into existing care models in a financially sustainable, scalable manner. Examples include Blue Zones Health, a new delivery model that aligns lifestyle medicine–certified clinicians with community and payers in California, and the University of Pittsburgh Medical Center lifestyle medicine program, where primary care patients are referred to virtual group coaching, a teaching kitchen, and classes on food as medicine, obesity, type 2 diabetes, and more.
Organizations dedicated to advancing primary care are paying close attention to the potential of lifestyle medicine. Currently, The Primary Care Collaborative has launched a new multi-year initiative on whole-person care and lifestyle medicine. This initiative aims to broaden the primary care community’s understanding of whole health and lifestyle medicine concepts and the evidence behind them, as well as lay the groundwork for future work to promote whole-person primary care and lifestyle medicine among an engaged and committed community of members.
Digital Tools and AI Spark Lifestyle Medicine Innovations
American College of Lifestyle Medicine partner organizations are increasingly utilizing digital tools, such as health apps tailored to lifestyle behavior interventions, to expand access to care and support behavior change. One of the biggest challenges in lifestyle interventions is the limited time during patient encounters. But artificial intelligence (AI) tools can record (with patient permission) and summarize encounters, enabling clinicians to turn away from their keyboards and be more present to learn about the unique living, environmental, and societal factors that impact every individual’s lifestyle choices. AI tools can create individualized whole-food, plant-predominant meal plans or physical activity schedules for patients in just a few seconds. The potential for AI in lifestyle medicine is vast, and its applications were further explored at the American College of Lifestyle Medicine’s annual conference in October.
Behavior Change and Sustainability of the Food-as-Medicine Movement
Significant investments have been made in food as medicine to address diet-related chronic diseases. But merely providing medically tailored meals or produce prescriptions is not enough because once the prescriptions end, so will the health benefits. Clinicians certified in lifestyle medicine are prepared to coach patients into long-term behavior change, supporting them with education and information to shop for and prepare tasty, nutritious, and affordable food. The same applies to the use of glucagon-like peptide 1 drugs. Although the initial weight loss offers motivation, lifestyle changes are necessary to sustain long-term health benefits beyond medications.
Lifestyle Medicine Emerges as a Strategy to Achieve Health Equity
Lifestyle behavior interventions have the unique ability to address health status and social drivers of health. For example, food as medicine affects an individual’s health while also addressing nutrition security. Certainly, no medication can both improve health status and feed someone. The addition of payment for the screening of social drivers of health to the 2024 Medicare Physician Fee Schedule is an important step toward connecting clinicians with community health–based organizations that can address factors that influence patients’ ability to adhere to lifestyle behavior care plans. Lifestyle medicine clinicians are poised to lead this effort because they are already having conversations with patients about their environment, living conditions, and access to nutritious food.
The changes coming to our healthcare system are exciting and long overdue. Lifestyle medicine is positioned to be at the forefront of this transformation now and in the future.

Treating Digestive Disease Across the Lifespan
Pediatric gastroenterologists are a vital, yet often overlooked segment of the GI workforce and an important part of AGA’s diverse membership. Per the American Board of Pediatrics, 2,232 pediatricians have been board certified in pediatric gastroenterology since formal certification was first offered in 1990, and AGA Institute Council’s Pediatric Gastroenterology and Developmental Biology Section has nearly 1,900 members.
According to a recently published study in the journal Pediatrics, the pediatric GI workforce is expected to double by 2040, growing at a rate faster than that of most other pediatric subspecialties. This is largely due to the increased scope and complexity of the field driven by scientific advances and the increasing prevalence of digestive and liver diseases in children, including inflammatory bowel and other diseases.
In this month’s Member Spotlight, we highlight Dr. Yoyo Zhang, a pediatric gastroenterologist at Stanford Children’s Health specializing in intestinal and liver transplantation. Her passion for her profession and for improving the lives of her patients shines brightly, and her interview provides fascinating insights into the complexities and rewards of the rapidly expanding field of pediatric gastroenterology.
Also in our November issue, we update you on the FDA’s recent approval of the “next-gen” Cologuard test and query a panel of primary care and GI experts on their thoughts regarding the role that newly FDA-approved (but not yet guideline-recommended) Guardant blood-based CRC screening test should play in CRC screening moving forward.
In our Perspectives feature, we offer expert insights on how to appropriately screen patients for certain rare malignancies. Is it worthwhile screening for pancreatic cancer, and if so, how should it be done? Likewise, diagnosing cholangiocarcinoma is challenging; how best should one evaluate for this in higher-risk populations?

Screening Options for Rare Malignancies
Dear colleagues,
As gastroenterologists and endoscopists, we spend significant time preventing and diagnosing GI malignancies.
For instance, is it worthwhile screening for pancreatic cancer, and, if so, how should this be done? Likewise, diagnosing cholangiocarcinoma is challenging; how best should one evaluate for this in higher risk populations, such as primary sclerosing cholangitis? And what about the costs, financial and otherwise, associated with screening?
In this issue of Perspectives, Dr. Darshan Kothari and Dr. Daniel Bernstein discuss their approach to pancreatic cancer screening, including who is eligible, the preferred screening modalities, and the barriers to screening. In the accompanying perspective, Dr. Aparna Goel and Dr. Judah Kupferman focus on cholangiocarcinoma screening, identifying high-risk populations and discussing some of the concerns with screening, necessitating shared decision-making.
We welcome your thoughts on this issue. Share with us on X at @AGA_GIHN.

An Approach to Pancreatic Cancer Screening
BY DANIEL A. BERNSTEIN, MD, AND DARSHAN KOTHARI, MD
Pancreatic cancer carries a dismal prognosis, now accounting for the third-most cancer-related mortality in the United States. A small proportion of patients are diagnosed at a local stage of disease, with over half found to have metastatic disease at presentation. Given the low overall incidence and lifetime risk in the general population, population-based screening is not justified.
About 10% of cases of pancreas cancer are associated with germ-line mutations and/or with a strong family history of pancreatic cancer. Several academic societies and expert committees now recommend regular screening for pancreatic cancer in patients who are considered high-risk individuals, as they carry a fivefold relative risk for pancreatic cancer. Moreover, studies suggest that screening has the potential to identify early-stage resectable disease and decrease mortality in this patient population.
Patients who benefit from pancreatic cancer screening are those who carry an increased lifetime risk (in excess of 5%) of pancreatic cancer. High-risk individuals include those with germ-line mutations and/or those with a family history of pancreatic cancer in first-degree relatives. Consensus guidelines by the International Cancer of the Pancreas Screening Consortium and the American Society for Gastrointestinal Endoscopy provide medical centers with detailed recommendations on who and when to start screening.
High-risk individuals fall into three categories:
- Patients with high-risk germline mutations including: familial atypical multiple mole melanoma syndrome (CDKN2A), hereditary breast and ovarian cancer syndromes (BRCA1, BRCA2, and PALB2), Peutz-Jeghers syndrome (STK11), and hereditary pancreatitis (PRSS1 and SPINK1)
- Patients with low- to moderate-risk germ-line mutations with at least one first-degree relative with pancreatic cancer: Lynch Syndrome (particularly MLH1 mutation), ataxia-telangiectasia (ATM), or Li-Fraumeni syndrome (p53)
- Patients with one first-degree relative with pancreatic cancer who in turn has one first-degree relative with pancreatic cancer (eg, a patient’s mother and maternal aunt or a patient’s father and patient’s sister)
Consistent with established guidelines, we recommend screening for high-risk patients beginning at age 50, or 10 years before the youngest age at which pancreas cancer was diagnosed in an affected relative. Screening is recommended earlier in patients with particularly high risk: at age 40 for patients with CDKN2A and STKI11 mutations and age 40 for patients with PRSS1 mutation or 20 years after the first attack of acute pancreatitis. For patients with a strong family history of pancreas cancer, we recommend comprehensive evaluation by a certified genetic counselor at a high-volume cancer center.
In practice, patients at our institution who are identified as high risk based on the above criteria are referred for an initial consultation at our pancreas center. In most cases, this should occur no sooner than 5 years prior to the recommended starting age for screening. All patients who are identified as high risk should be screened annually for diabetes given the growing evidence base supporting an association between new-onset diabetes and pancreatic cancer.
After an initial visit and discussion of the risks and benefits of screening, most screening protocols start with a baseline endoscopic ultrasound (EUS) and contrast-enhanced magnetic resonance abdomen with magnetic resonance cholangiopancreatography (MRI/MRCP), which will be repeated annually or sooner as the clinical condition warrants. A sooner-interval EUS should be considered for patients already undergoing screening who are newly found to have diabetes.
At our institution, we start with an in-person clinic evaluation followed by EUS. Thereafter, patients undergo MRI/MRCP (synchronized with a same-day clinic visit) alternating with EUS every 6 months to ensure patients are seen twice a year, though there is no specific data to support this approach. Non-diabetics also undergo yearly diabetes screening which will trigger an EUS if patients become diabetic.
We engage in shared decision-making with our high-risk individuals undergoing pancreatic cancer screening and at each visit we review their concurrent medical conditions and suitability to continue screening. We consider discontinuing screening after age 75, at the onset of any life-limiting illness, or after a discussion of risks and benefits if comorbidities lead to a substantial deterioration in a patient’s overall health status.
While a growing body of evidence exists to support the application of pancreatic cancer screening in high-risk individuals, this preventive service remains underutilized. Recent analysis of the screening cohort at our institution showed a demographically homogeneous group of mostly highly educated, high-income White females. These findings are consistent with the patient cohorts described in other pancreatic cancer screening programs and represent only a fraction of people who would qualify for pancreatic cancer screening.
A survey of patients undergoing screening at our institution identified cost, travel, and time associated with pancreatic cancer screening to be frequent challenges to participation. Further studies are needed to fully explore the barriers and psychological burden of pancreas cancer screening in high-risk individuals, and to identify ways to enrich the cohort of patients undergoing screening. This may involve novel methods to identify family members of patients with a new diagnosis of pancreas cancer and increasing health literacy around pancreatic cancer screening among patients and providers.
Pancreatic cancer screening has the potential to identify early-stage disease in patients who are at high risk because of germ-line mutations and/or family history. We recommend that patients engage in pancreatic cancer screening at high-volume centers with well-supported oncology, genetics, and research infrastructure.

Screening for Cholangiocarcinoma
BY JUDAH KUPFERMAN, MD, AND APARNA GOEL, MD
Cholangiocarcinoma is a rare but aggressive cancer of the bile ducts that poses many diagnostic challenges. Approximately 3% of gastrointestinal cancers are attributed to cholangiocarcinoma, and while the annual incidence of disease in the United States is about 1.26 per 100,000 people, the incidence of intrahepatic disease has been rising considerably.1,2 Screening for cholangiocarcinoma is reserved for high-risk individuals — such as those with primary sclerosing cholangitis (PSC), secondary sclerosing cholangitis (SSC), and biliary tract disorders such as choledochal cysts or Caroli’s disease. The goal is to balance the benefits of early diagnosis with the costs and risks associated with screening, particularly given the limitations of available tools like MRI with cholangiopancreatography (MRCP), which has a sensitivity of 70%-85%. In general, we recommend annual cholangiocarcinoma screening for high-risk individuals with MRI and MRCP as well as with cancer antigen (CA) 19-9. .
Screening in Patients with Primary Sclerosing Cholangitis
The lifetime risk of cholangiocarcinoma in patients with PSC is 10%-15% with an annual risk of 0.5%-1.5%. In our experience, this is often the most feared complication for PSC patients, even more so than the risk of liver transplantation. We recommend annual MRI with MRCP in addition to CA 19-9 for patients with PSC in the first decade of their diagnosis, as most cancers are diagnosed during this period. If a patient’s imaging has remained stable for over a decade and there is minimal hepatic fibrosis, we discuss the option of reducing screening frequency to every 2 years to minimize costs and exposure to MRI contrast risks.
If MRI reveals a concerning new large duct stricture, we will evaluate this with an endoscopic retrograde cholangiopancreatography (ERCP), as differentiating benign and malignant strictures is quite challenging with MRI. We generally recommend ERCP with brush cytology and fluorescence in situ hybridization to improve diagnostic yield. Depending on imaging findings and location of the new large duct stricture, we may consider cholangioscopy during ERCP for direct visualization of the bile duct and directed tissue biopsies. Unfortunately, even in young, asymptomatic patients who undergo regular screening, cholangiocarcinoma is frequently diagnosed at an advanced stage.
Screening in Patients with Secondary Sclerosing Cholangitis
Patients with SSC may develop cholangiocarcinoma because of chronic inflammatory and fibrotic processes, such as IgG4-associated cholangiopathy, sarcoidosis, ischemic cholangiopathy, cystic fibrosis, recurrent pyogenic cholangitis, severe sepsis (as recently seen from SARS-CoV-2), surgical complications, or other etiologies. When the condition is reversible, such as with IgG4-associated cholangiopathy, cancer screening may not be necessary. However, when irreversible damage occurs, the cancer risk increases, though it varies by disease type and severity. In most cases, we recommend routine screening for cholangiocarcinoma with MRI and CA 19-9 in this population.
Screening in Patients with Biliary Tract Disorders
Biliary tract disorders such as choledochal cysts and Caroli’s disease also harbor an increased risk of cholangiocarcinoma. Choledochal cysts are congenital cystic dilations of the bile duct that have a 10%-30% lifetime risk of malignant transformation to cholangiocarcinoma. Surgical intervention to remove the cyst is often recommended because of this high risk. However, some patients may be unable or unwilling to undergo this surgery or they may have residual cysts. We recommend ongoing screening with MRI and CA 19-9 for these patients. Similarly, Caroli’s disease is a congenital disease associated with intrahepatic and extrahepatic bile duct cysts and associated with a 5%-15% lifetime risk of cholangiocarcinoma. MRI with MRCP and CA 19-9 should be performed routinely for patients with Caroli’s disease and syndrome.
Risks and Challenges in Cholangiocarcinoma Screening
While MRI with MRCP is the gold standard for cholangiocarcinoma screening, its limitations must be carefully considered. One growing concern is the potential for gadolinium retention in the brain, bones, or skin following repeated MRI scans. Though the long-term effects of gadolinium retention are not fully understood, we factor this into screening decisions, particularly for younger patients who may undergo decades of regular imaging.
MRI is not always feasible for certain patients, including those with metal implants, on hemodialysis, or with severe allergic reactions. In such cases, CT or ultrasound may serve as alternatives, though with lower sensitivity for detecting cholangiocarcinoma. Additionally, claustrophobia during MRI can be addressed with sedation, but this underscores the importance of shared decision-making.
From our perspective, cholangiocarcinoma screening in high-risk patients is crucial but not without challenges. Our current screening methods, while essential, are far from perfect, often missing early cancers or leading to unnecessary interventions. Because of these limitations, the window for treatment of localized disease can easily be missed. In our practice, we tailor screening strategies to each patient’s specific needs, weighing the potential benefits against the risks, costs, and the inherent uncertainty of early detection tools. We believe it is essential to involve patients in this decision-making process to provide a balanced, individualized approach that considers both clinical evidence and the personal preferences of each person.

High-risk individuals include those with germ-line mutations and/or those with a family history of pancreatic cancer in first-degree relatives. Consensus guidelines by the International Cancer of the Pancreas Screening Consortium and the American Society for Gastrointestinal Endoscopy provide medical centers with detailed recommendations on who and when to start screening.
High-risk individuals fall into three categories:
- Patients with high-risk germline mutations including: familial atypical multiple mole melanoma syndrome (CDKN2A), hereditary breast and ovarian cancer syndromes (BRCA1, BRCA2, and PALB2), Peutz-Jeghers syndrome (STK11), and hereditary pancreatitis (PRSS1 and SPINK1)
- Patients with low- to moderate-risk germ-line mutations with at least one first-degree relative with pancreatic cancer: Lynch Syndrome (particularly MLH1 mutation), ataxia-telangiectasia (ATM), or Li-Fraumeni syndrome (p53)
- Patients with one first-degree relative with pancreatic cancer who in turn has one first-degree relative with pancreatic cancer (eg, a patient’s mother and maternal aunt or a patient’s father and patient’s sister)
Consistent with established guidelines, we recommend screening for high-risk patients beginning at age 50, or 10 years before the youngest age at which pancreas cancer was diagnosed in an affected relative. Screening is recommended earlier in patients with particularly high risk: at age 40 for patients with CDKN2A and STKI11 mutations and age 40 for patients with PRSS1 mutation or 20 years after the first attack of acute pancreatitis. For patients with a strong family history of pancreas cancer, we recommend comprehensive evaluation by a certified genetic counselor at a high-volume cancer center.
In practice, patients at our institution who are identified as high risk based on the above criteria are referred for an initial consultation at our pancreas center. In most cases, this should occur no sooner than 5 years prior to the recommended starting age for screening. All patients who are identified as high risk should be screened annually for diabetes given the growing evidence base supporting an association between new-onset diabetes and pancreatic cancer.
After an initial visit and discussion of the risks and benefits of screening, most screening protocols start with a baseline endoscopic ultrasound (EUS) and contrast-enhanced magnetic resonance abdomen with magnetic resonance cholangiopancreatography (MRI/MRCP), which will be repeated annually or sooner as the clinical condition warrants. A sooner-interval EUS should be considered for patients already undergoing screening who are newly found to have diabetes.
At our institution, we start with an in-person clinic evaluation followed by EUS. Thereafter, patients undergo MRI/MRCP (synchronized with a same-day clinic visit) alternating with EUS every 6 months to ensure patients are seen twice a year, though there is no specific data to support this approach. Non-diabetics also undergo yearly diabetes screening which will trigger an EUS if patients become diabetic.
We engage in shared decision-making with our high-risk individuals undergoing pancreatic cancer screening and at each visit we review their concurrent medical conditions and suitability to continue screening. We consider discontinuing screening after age 75, at the onset of any life-limiting illness, or after a discussion of risks and benefits if comorbidities lead to a substantial deterioration in a patient’s overall health status.
While a growing body of evidence exists to support the application of pancreatic cancer screening in high-risk individuals, this preventive service remains underutilized. Recent analysis of the screening cohort at our institution showed a demographically homogeneous group of mostly highly educated, high-income White females. These findings are consistent with the patient cohorts described in other pancreatic cancer screening programs and represent only a fraction of people who would qualify for pancreatic cancer screening.
A survey of patients undergoing screening at our institution identified cost, travel, and time associated with pancreatic cancer screening to be frequent challenges to participation. Further studies are needed to fully explore the barriers and psychological burden of pancreas cancer screening in high-risk individuals, and to identify ways to enrich the cohort of patients undergoing screening. This may involve novel methods to identify family members of patients with a new diagnosis of pancreas cancer and increasing health literacy around pancreatic cancer screening among patients and providers.
Pancreatic cancer screening has the potential to identify early-stage disease in patients who are at high risk because of germ-line mutations and/or family history. We recommend that patients engage in pancreatic cancer screening at high-volume centers with well-supported oncology, genetics, and research infrastructure.

Screening for Cholangiocarcinoma
BY JUDAH KUPFERMAN, MD, AND APARNA GOEL, MD
Cholangiocarcinoma is a rare but aggressive cancer of the bile ducts that poses many diagnostic challenges. Approximately 3% of gastrointestinal cancers are attributed to cholangiocarcinoma, and while the annual incidence of disease in the United States is about 1.26 per 100,000 people, the incidence of intrahepatic disease has been rising considerably.1,2 Screening for cholangiocarcinoma is reserved for high-risk individuals — such as those with primary sclerosing cholangitis (PSC), secondary sclerosing cholangitis (SSC), and biliary tract disorders such as choledochal cysts or Caroli’s disease. The goal is to balance the benefits of early diagnosis with the costs and risks associated with screening, particularly given the limitations of available tools like MRI with cholangiopancreatography (MRCP), which has a sensitivity of 70%-85%. In general, we recommend annual cholangiocarcinoma screening for high-risk individuals with MRI and MRCP as well as with cancer antigen (CA) 19-9. .
Screening in Patients with Primary Sclerosing Cholangitis
The lifetime risk of cholangiocarcinoma in patients with PSC is 10%-15% with an annual risk of 0.5%-1.5%. In our experience, this is often the most feared complication for PSC patients, even more so than the risk of liver transplantation. We recommend annual MRI with MRCP in addition to CA 19-9 for patients with PSC in the first decade of their diagnosis, as most cancers are diagnosed during this period. If a patient’s imaging has remained stable for over a decade and there is minimal hepatic fibrosis, we discuss the option of reducing screening frequency to every 2 years to minimize costs and exposure to MRI contrast risks.
If MRI reveals a concerning new large duct stricture, we will evaluate this with an endoscopic retrograde cholangiopancreatography (ERCP), as differentiating benign and malignant strictures is quite challenging with MRI. We generally recommend ERCP with brush cytology and fluorescence in situ hybridization to improve diagnostic yield. Depending on imaging findings and location of the new large duct stricture, we may consider cholangioscopy during ERCP for direct visualization of the bile duct and directed tissue biopsies. Unfortunately, even in young, asymptomatic patients who undergo regular screening, cholangiocarcinoma is frequently diagnosed at an advanced stage.
Screening in Patients with Secondary Sclerosing Cholangitis
Patients with SSC may develop cholangiocarcinoma because of chronic inflammatory and fibrotic processes, such as IgG4-associated cholangiopathy, sarcoidosis, ischemic cholangiopathy, cystic fibrosis, recurrent pyogenic cholangitis, severe sepsis (as recently seen from SARS-CoV-2), surgical complications, or other etiologies. When the condition is reversible, such as with IgG4-associated cholangiopathy, cancer screening may not be necessary. However, when irreversible damage occurs, the cancer risk increases, though it varies by disease type and severity. In most cases, we recommend routine screening for cholangiocarcinoma with MRI and CA 19-9 in this population.
Screening in Patients with Biliary Tract Disorders
Biliary tract disorders such as choledochal cysts and Caroli’s disease also harbor an increased risk of cholangiocarcinoma. Choledochal cysts are congenital cystic dilations of the bile duct that have a 10%-30% lifetime risk of malignant transformation to cholangiocarcinoma. Surgical intervention to remove the cyst is often recommended because of this high risk. However, some patients may be unable or unwilling to undergo this surgery or they may have residual cysts. We recommend ongoing screening with MRI and CA 19-9 for these patients. Similarly, Caroli’s disease is a congenital disease associated with intrahepatic and extrahepatic bile duct cysts and associated with a 5%-15% lifetime risk of cholangiocarcinoma. MRI with MRCP and CA 19-9 should be performed routinely for patients with Caroli’s disease and syndrome.
Risks and Challenges in Cholangiocarcinoma Screening
While MRI with MRCP is the gold standard for cholangiocarcinoma screening, its limitations must be carefully considered. One growing concern is the potential for gadolinium retention in the brain, bones, or skin following repeated MRI scans. Though the long-term effects of gadolinium retention are not fully understood, we factor this into screening decisions, particularly for younger patients who may undergo decades of regular imaging.
MRI is not always feasible for certain patients, including those with metal implants, on hemodialysis, or with severe allergic reactions. In such cases, CT or ultrasound may serve as alternatives, though with lower sensitivity for detecting cholangiocarcinoma. Additionally, claustrophobia during MRI can be addressed with sedation, but this underscores the importance of shared decision-making.
From our perspective, cholangiocarcinoma screening in high-risk patients is crucial but not without challenges. Our current screening methods, while essential, are far from perfect, often missing early cancers or leading to unnecessary interventions. Because of these limitations, the window for treatment of localized disease can easily be missed. In our practice, we tailor screening strategies to each patient’s specific needs, weighing the potential benefits against the risks, costs, and the inherent uncertainty of early detection tools. We believe it is essential to involve patients in this decision-making process to provide a balanced, individualized approach that considers both clinical evidence and the personal preferences of each person.

Dear colleagues,
As gastroenterologists and endoscopists, we spend significant time preventing and diagnosing GI malignancies.
For instance, is it worthwhile screening for pancreatic cancer, and, if so, how should this be done? Likewise, diagnosing cholangiocarcinoma is challenging; how best should one evaluate for this in higher risk populations, such as primary sclerosing cholangitis? And what about the costs, financial and otherwise, associated with screening?
In this issue of Perspectives, Dr. Darshan Kothari and Dr. Daniel Bernstein discuss their approach to pancreatic cancer screening, including who is eligible, the preferred screening modalities, and the barriers to screening. In the accompanying perspective, Dr. Aparna Goel and Dr. Judah Kupferman focus on cholangiocarcinoma screening, identifying high-risk populations and discussing some of the concerns with screening, necessitating shared decision-making.
We welcome your thoughts on this issue. Share with us on X at @AGA_GIHN.

An Approach to Pancreatic Cancer Screening
BY DANIEL A. BERNSTEIN, MD, AND DARSHAN KOTHARI, MD
Pancreatic cancer carries a dismal prognosis, now accounting for the third-most cancer-related mortality in the United States. A small proportion of patients are diagnosed at a local stage of disease, with over half found to have metastatic disease at presentation. Given the low overall incidence and lifetime risk in the general population, population-based screening is not justified.
About 10% of cases of pancreas cancer are associated with germ-line mutations and/or with a strong family history of pancreatic cancer. Several academic societies and expert committees now recommend regular screening for pancreatic cancer in patients who are considered high-risk individuals, as they carry a fivefold relative risk for pancreatic cancer. Moreover, studies suggest that screening has the potential to identify early-stage resectable disease and decrease mortality in this patient population.
Patients who benefit from pancreatic cancer screening are those who carry an increased lifetime risk (in excess of 5%) of pancreatic cancer.

Managing Age-Related Muscle Loss in Primary Care
Scene 1: Exercise Medicine Clinic, Rio de Janeiro, Brazil I just finished one evaluation on physical fitness and health and looked at my schedule. My next patient would be a 65-year-old man. How fit will he be? Will he have evident age-related muscle loss? I gave myself a short break and my mind went to the late 1970s.
Once upon a time, the practice of medicine was based primarily on the skill of your physical examination, previous experiences, and your ability to reason logically and make solid deductions. In 1979, the stethoscope was part of my dress code. After one elective semester as a research fellow at the Ambrose Cardiorespiratory Unit at McMaster University Medical Centre, in Hamilton, Canada, where I was honored to witness the dawn of evidence-based medicine, I graduated from Federal University of Rio de Janeiro. I still remember being introduced to some promising novelties in cardiology, such as M-mode echocardiograms and myocardial scintigraphy. Radiology was primarily centered on x-rays, and lab testing was basic and poorly automatized.
Over the following decades, medical practice changed dramatically with the incorporation of new technologies. Recent advances in diagnostic tools, genetics, artificial intelligence, and sophisticated statistical analyses, along with well-collected scientific data, have molded how clinicians should think and work.
At the same time, clinical profiles also changed. Internists and primary care physicians are regularly managing patients who are, on average, older and have or are on the way to having potentially life-threatening chronic diseases, accompanied by poor lifestyle habits, and, highly important, often some degree of disability, frailty, and loss of independence. Many of them exhibit age-related muscle loss.
Scene 2: Exercise Medicine Clinic, Rio de Janeiro, Brazil
Conscious of the benefits of interrupting my sitting time with activity, I left my office and walked to meet my patient in the waiting room. I called his name and introduced myself. I watched how he listened and reacted to my speech, and how easy or hard it was for him to rise from the chair — readiness, velocity, and number of supports required: none, one, or two hands. I offered my own hand to him, and when we shook, I gauged the strength of his grip.
I invited him into my office and took note of his somatotype and body composition, and whether he had any central obesity. Of course, and I should by no means miss this chance, I carefully observed how he walked in — his gait, speed, balance, posture — how he pulled up the chair, and how he managed to lower himself into his seat. Before I even sat in my own chair, I asked him if he remembered what his body weight was 5 years ago and what it was today. Before we got started in earnest, I had already managed to collect several pieces of relevant information.
Exercise Physiology: Changing Landscape
Muscle activity depends on muscle mass and function, and peaks somewhere between ages 25 and 35 before declining. The drop is slow in the early stages but accelerates rapidly after age 60 or 65.
Two of the most relevant variables in muscle function are strength and power. As a product of force and velocity, muscle power could be a more crucial factor than strength for many daily activities that demand movement against gravity or inertia, such as placing carry-on baggage in the overhead bin of an airplane or rising from the floor or chair.
The association between muscle mass and muscle strength or power is moderate, and physiologic data have indicated that the decline of muscle power with aging is faster and larger than that of muscle strength.
The term “sarcopenia” has become definitively incorporated into the medical glossary. From the Greek (“sark” and “penia”), sarcopenia was defined as reduced muscle mass, but more recently it has encompassed muscle strength in its definition. However, a recent consensus paper from the Global Leadership Initiative in Sarcopenia, using a Delphi approach, rejected the inclusion of muscle power in the concept of sarcopenia. On the other hand, a long time ago, some authors coined and advocated the use the term “dynapenia” to more precisely reflect the reduced levels of muscle strength and power that often accompany aging.
The best available intervention to counteract age-related deterioration of muscle activity is resistance exercise. The types of resistance exercises vary widely — by number of sets and repetitions, intervals between sets, speed of execution of movement, and percentage of maximal weight/load.
We recently proposed that, after an evaluation to identify the main muscle variable requiring attention, the resistance exercise program should be individually tailored and prescribed according to the objective to counteract sarcopenia or dynapenia.
What is more important for autonomy and better daily living conditions in old and very old individuals: muscle mass, muscle strength, or muscle power? More likely the response is muscle power — in practical terms, dynapenia rather than sarcopenia. This short video presents practical tips for obtaining optimal results in fighting dynapenia. The first choice should be power training or high velocity–based training, emphasizing two to three sets of six to eight repetitions performed as fast as possible (on the concentric or shortening phase of muscle contraction) with relatively high loads.
Internists and primary care physicians are most likely satisfied with the information they obtain by simple observation, and already can superficially grade the magnitude of a patient’s age-related muscle loss and its consequences to daily living.
However, those who want more objective information on nonaerobic physical fitness can add one to three simple tests to their consultation: the sitting-rising test (SRT); the 10-second one-legged test (10sOLS test); and the Flexitest. Poor performance on each of these — and particularly all three — is strongly associated with an increased risk for premature death in middle-aged and older individuals. These tests require no extra equipment and can be performed rapidly, and interpreting the results takes only a few moments using published reference values.
Age-related muscle loss profoundly affects our ability to sit and rise from the floor, so if time is limited, the SRT is the best assessment, as it measures all nonaerobic components of physical fitness. For a quick interpretation, consider that SRT scores vary from 0 to 10, do not substantially differ by sex, and that a composite score equal to or greater than 8 will reflect a minimum age-adjusted percentile of 61, most likely indicating relevant age-related muscle loss is not yet occurring.

For a quick interpretation, consider that SRT scores vary from 0 to 10, do not substantially differ by sex, and that a composite score equal to or greater than 8 will reflect a minimum age-adjusted percentile of 61, most likely indicating relevant age-related muscle loss is not yet occurring.

Scene 1: Exercise Medicine Clinic, Rio de Janeiro, Brazil I just finished one evaluation on physical fitness and health and looked at my schedule. My next patient would be a 65-year-old man. How fit will he be? Will he have evident age-related muscle loss? I gave myself a short break and my mind went to the late 1970s.
Once upon a time, the practice of medicine was based primarily on the skill of your physical examination, previous experiences, and your ability to reason logically and make solid deductions. In 1979, the stethoscope was part of my dress code. After one elective semester as a research fellow at the Ambrose Cardiorespiratory Unit at McMaster University Medical Centre, in Hamilton, Canada, where I was honored to witness the dawn of evidence-based medicine, I graduated from Federal University of Rio de Janeiro. I still remember being introduced to some promising novelties in cardiology, such as M-mode echocardiograms and myocardial scintigraphy. Radiology was primarily centered on x-rays, and lab testing was basic and poorly automatized.
Over the following decades, medical practice changed dramatically with the incorporation of new technologies. Recent advances in diagnostic tools, genetics, artificial intelligence, and sophisticated statistical analyses, along with well-collected scientific data, have molded how clinicians should think and work.
At the same time, clinical profiles also changed. Internists and primary care physicians are regularly managing patients who are, on average, older and have or are on the way to having potentially life-threatening chronic diseases, accompanied by poor lifestyle habits, and, highly important, often some degree of disability, frailty, and loss of independence. Many of them exhibit age-related muscle loss.
Scene 2: Exercise Medicine Clinic, Rio de Janeiro, Brazil
Conscious of the benefits of interrupting my sitting time with activity, I left my office and walked to meet my patient in the waiting room. I called his name and introduced myself. I watched how he listened and reacted to my speech, and how easy or hard it was for him to rise from the chair — readiness, velocity, and number of supports required: none, one, or two hands. I offered my own hand to him, and when we shook, I gauged the strength of his grip.
I invited him into my office and took note of his somatotype and body composition, and whether he had any central obesity. Of course, and I should by no means miss this chance, I carefully observed how he walked in — his gait, speed, balance, posture — how he pulled up the chair, and how he managed to lower himself into his seat. Before I even sat in my own chair, I asked him if he remembered what his body weight was 5 years ago and what it was today. Before we got started in earnest, I had already managed to collect several pieces of relevant information.
Exercise Physiology: Changing Landscape
Muscle activity depends on muscle mass and function, and peaks somewhere between ages 25 and 35 before declining. The drop is slow in the early stages but accelerates rapidly after age 60 or 65.
Two of the most relevant variables in muscle function are strength and power. As a product of force and velocity, muscle power could be a more crucial factor than strength for many daily activities that demand movement against gravity or inertia, such as placing carry-on baggage in the overhead bin of an airplane or rising from the floor or chair.
The association between muscle mass and muscle strength or power is moderate, and physiologic data have indicated that the decline of muscle power with aging is faster and larger than that of muscle strength.
The term “sarcopenia” has become definitively incorporated into the medical glossary. From the Greek (“sark” and “penia”), sarcopenia was defined as reduced muscle mass, but more recently it has encompassed muscle strength in its definition. However, a recent consensus paper from the Global Leadership Initiative in Sarcopenia, using a Delphi approach, rejected the inclusion of muscle power in the concept of sarcopenia. On the other hand, a long time ago, some authors coined and advocated the use the term “dynapenia” to more precisely reflect the reduced levels of muscle strength and power that often accompany aging.
The best available intervention to counteract age-related deterioration of muscle activity is resistance exercise. The types of resistance exercises vary widely — by number of sets and repetitions, intervals between sets, speed of execution of movement, and percentage of maximal weight/load.
We recently proposed that, after an evaluation to identify the main muscle variable requiring attention, the resistance exercise program should be individually tailored and prescribed according to the objective to counteract sarcopenia or dynapenia.
What is more important for autonomy and better daily living conditions in old and very old individuals: muscle mass, muscle strength, or muscle power? More likely the response is muscle power — in practical terms, dynapenia rather than sarcopenia. This short video presents practical tips for obtaining optimal results in fighting dynapenia. The first choice should be power training or high velocity–based training, emphasizing two to three sets of six to eight repetitions performed as fast as possible (on the concentric or shortening phase of muscle contraction) with relatively high loads.
Internists and primary care physicians are most likely satisfied with the information they obtain by simple observation, and already can superficially grade the magnitude of a patient’s age-related muscle loss and its consequences to daily living.
However, those who want more objective information on nonaerobic physical fitness can add one to three simple tests to their consultation: the sitting-rising test (SRT); the 10-second one-legged test (10sOLS test); and the Flexitest. Poor performance on each of these — and particularly all three — is strongly associated with an increased risk for premature death in middle-aged and older individuals. These tests require no extra equipment and can be performed rapidly, and interpreting the results takes only a few moments using published reference values.
