Family Practice News

For decades I have suspected that there is a strong association between sleep deprivation and pediatric attention disorders. More recently I have wondered whether screen time, particularly at bedtime might be a significant contributor to sleep quantity and quality in both children and adults. There is a growing body of research that combines my two observations and suggests that bedtime screen time through its effect on sleep may be linked to pediatric attention problems. However, most of this work is preliminary and needs to be confirmed.

Stumbling across a paper from England titled “Toddler Screen Use Before Bed and Its Effect on Sleep and Attention” renewed my hope that we finally have evidence to close that knowledge gap. My bubble burst quickly however when I jumped ahead and read the conclusion portion of the abstract and learned that authors observed “no clear difference in parent reported attention” in the group of children in which screen time before bedtime had been eliminated. The authors wonder if their small study sample may be to blame.

 

Disappointed, I persisted and read the paper in its entirety and found that despite their failure to link bedtime screen time with attention disorders, the investigators have made a significant contribution to our understanding of how we can better encourage good pediatric sleep hygiene. 

 

The Study

One hundred and five families with a toddler who was being exposed to a video screen in the hour before bedtime were divided into three groups. One group received guidance and advice from a pediatric team about the potential benefit of eliminating bedtime screen time. They were also given a box of activities that contained “activity cards and age appropriate toys” to replace the screen use. The family also received periodic support and follow-up contacts. A second group received only the “bedtime box.” And the third received no intervention.

It is important to note that the investigators modeled their intervention on one developed in a previous study using older children that was “co-created with caregivers and early years practitioners”(my italics). 

The intervention resulted in reductions in parent-reported screen time, sleep efficiency, night awakenings, and daytime sleep. The decrease in nap time was a surprise to the investigators. 

These reductions were small. However, the investigators were most impressed (and I share in their sentiment) with the finding that 99% (104/105) of the families stayed with the study until completion, demonstrating that future studies using this format were highly feasible. The authors of the study were pleased also and possibly surprised that 94% (33/35) of the families who received the intervention adhered to the recommendations. 

 

One Suggestion: ‘Just Shut the TV Off’

If you are a cynic, you might be tempted to explain the investigators’ (and my) excitement over the feasibility and adherence numbers as an attempt to pump up the importance of a set of otherwise lackluster numbers regarding sleep and the failure to find any association between the intervention and attention. However, having spent a large part of my career trying to encourage parents to improve their child’s sleep hygiene, often with little success, I am encouraged by this study’s success in getting families to accept and then adhere to the intervention.

I must admit that when presented with a child who appeared to be having some attention difficulties and was watching television as part of his or her bedtime ritual, there’s a good chance I would have simply told the parents, “Just shut the TV off.” This certainly worked with some families, particularly those who had already bought into my preaching about the importance of sleep. However, my acceptance and adherence rates were no where near the 99% and 94% these investigators where achieving. 

I did try to make follow-up phone calls, as these investigators did, but generally only to the most seriously effected families or in situations in which felt I was going to have the greatest chance of success. I am sorry to say that I didn’t involve the parents in crafting my overly simplistic intervention. Had I been more open to parental input, I suspect my results would have improved.

 

An Alternative

I think another reason for these investigators’ success was the clever ploy of offering a replacement (in this case the bedtime box of alternative activities) when they asked the parents to remove the screen time. Getting anyone to break an unhealthy habit, be they parents or patients, it often helps to offer them an alternative. The activity may not be as appealing as their current behavior but it can fill the gap until a new even healthier behavior develops.

Building an efficient and effective bedtime ritual begins in the first months of life. The initial challenge could be separating nursing or a bottle from the settling in process. Later on it could mean helping a parent who is out of the home all day understand that they may have to suppress their natural urge to engage in vigorous play with his/her child at a time that is best devoted to winding down into a healthy bedtime ritual. Although screen time may not be physically stimulating, there is increasing evidence that it shouldn’t be part of a pre-bedtime ritual. The question of if and how it contributes to attention problems will have to wait until another day.

You’re invited to a dinner party but you struggle to make small talk. Do not worry; you can use your knowledge of study design and epidemiology to impress people with your savoir faire regarding popular food myths that will invariably crop up over cocktails. Because all journalism has been reduced to listicles, here are four ways to seem clever at dinner parties.

1. The Predinner Cocktails: A Lesson in Reverse Causation

Wine connoisseurs sniff, swirl, and gently swish the wine in their mouths before spitting out and cleansing their palates to better appreciate the subtlety of each vintage. If you’re not an oenophile, no matter. Whenever somebody claims that moderate amounts of alcohol are good for your heart, this is your moment to pounce. Interject yourself in the conversation and tell everybody about reverse causation.

Reverse causation, also known as protopathic bias, involves misinterpreting the directionality of an association. You assume that X leads to Y, when in fact Y leads to X. Temporal paradoxes are useful plot devices in science fiction movies, but they have no place in medical research. In our bland world, cause must precede effect. As such, smoking leads to lung cancer; lung cancer doesn’t make you smoke more. 

But with alcohol, directionality is less obvious. Many studies of alcohol and cardiovascular disease have demonstrated a U-shaped association, with risk being lowest among those who drink moderate amounts of alcohol (usually one to two drinks per day) and higher in those who drink more and also those who drink very little.

But one must ask why some people drink little or no alcohol. There is an important difference between former drinkers and never drinkers. Former drinkers cut back for a reason. More likely than not, the reason for this newfound sobriety was medical. A new cancer diagnosis, the emergence of atrial fibrillation, the development of diabetes, or rising blood pressure are all good reasons to reduce or eliminate alcohol. A cross-sectional study will fail to capture that alcohol consumption changes over time — people who now don’t drink may have imbibed alcohol in years past. It was not abstinence that led to an increased risk for heart disease; it was the increased risk for heart disease that led to abstinence.

You see the same phenomenon with the so-called obesity paradox. The idea that being a little overweight is good for you may appeal when you no longer fit into last year’s pants. But people who are underweight are so for a reason. Malnutrition, cachexia from cancer, or some other cause is almost certainly driving up the risk at the left-hand side of the U-shaped curve that makes the middle part seem better than it actually is.

Food consumption changes over time. A cross-sectional survey at one point in time cannot accurately capture past habits and distant exposures, especially for diseases such as heart disease and cancer that develop slowly over time. Studies on alcohol that try to overcome these shortcomings by eliminating former drinkers, or by using Mendelian randomization to better account for past exposure, do not show a cardiovascular benefit for moderate red wine drinking.

 

2. The Hors D’oeuvres — The Importance of RCTs

Now that you have made yourself the center of attention, it is time to cement your newfound reputation as a font of scientific knowledge. Most self-respecting hosts will serve smoked salmon as an amuse-bouche before the main meal. When someone mentions the health benefits of fish oils, you should take the opportunity to teach them about confounding.

Fish, especially cold-water fish from northern climates, have relatively high amounts of omega-3 fatty acids. Despite the plethora of observational studies suggesting a cardiovascular benefit, it’s now relatively clear that fish oil or omega-3 supplements have no medical benefit.

This will probably come as a shock to the worried well, but many studies, including VITAL and ASCEND, have demonstrated no cardiovascular or cancer benefit to supplementation with omega-3s. The reason is straightforward and explains why hormone replacement therapy, vitamin D, and myriad purported game-changers never panned out. Confounding is hard to overcome in observational research.

Prior to the publication of the Women’s Health Initiative (WHI) Study, hormone replacement therapy was routinely prescribed to postmenopausal women because numerous observational studies suggested a cardiovascular benefit. But with the publication of the WHI study, it became clear that much of that “benefit” was due to confounding. The women choosing to take hormones were more health conscious at baseline and healthier overall. 

A similar phenomenon occurred during COVID. Patients with low serum vitamin D levels had worse outcomes, prompting many to suggest vitamin D supplementation as a possible treatment. Trials did not support the intervention because we’d overlooked the obvious. People with vitamin D deficiency have underlying health problems that contribute to the vitamin D deficiency. They are probably older, frailer, possibly with a poorer diet. No amount of statistical adjustment can account for all those differences, and some degree of residual confounding will always persist.

The only way to overcome confounding is with randomization. When patients are randomly assigned to one group or another, their baseline differences largely balance out if the randomization was performed properly and the groups were large enough. There is a role for observational research, such as in situations where ethics, cost, and practicality do not allow for a randomized controlled trial. But randomized controlled trials have largely put to rest the purported health benefits of over-the-counter fish oils, omega-3s, and vitamin D.

 

3. The Main Course — Absolute vs Relative Risk

When you get to the main course, all eyes will now be on you. You will almost certainly be called upon to pronounce on the harms or benefits of red meat consumption. Begin by regaling your guests with a little trivia. Ask them if they know the definition of red meat and white meat. When someone says pork is white meat, you can reveal that “pork, the other white meat,” was a marketing slogan with no scientific underpinning. Now that everyone is lulled into a stupefied silence, tell them that red meat comes from mammals and white meat comes from birds. As they process this revelation, you can now launch into the deeply mathematical concept of absolute vs relative risk.

Many etiquette books will caution against bringing up math at a dinner party. These books are wrong. Everyone finds math interesting if they are primed properly. For example, you can point to a study claiming that berries reduce cardiovascular risk in women. Even if true — and there is reason to be cautious, given the observational nature of the research — we need to understand what the authors meant by a 32% risk reduction. (Side note: It was a reduction in hazard, with a hazard ratio of 0.68 (95% CI, 0.49-0.96), but we won’t dwell on the difference between hazard ratios and risk ratios right now.)

This relative risk reduction has to be interpreted carefully. The authors divided the population into quintiles based on their consumption of anthocyanins (the antioxidant in blueberries and strawberries) and compared the bottom fifth (average consumption, 2.5 mg/d) with the top fifth (average consumption, 25 mg/d). The bottom quintile had 126 myocardial infarctions (MIs) over 324,793 patient-years compared with 59 MIs over 332,143 patient-years. Some quick math shows an approximate reduction from 39 to 18 MIs per 100,000 patient-years. Or to put it another way, you must get 4762 women to increase their berry consumption 10-fold for 1 year to prevent one heart attack. Feel free to show people how you calculated this number. They will be impressed by your head for numbers. It is nothing more than 39 minus 18, divided by 100,000, to get the absolute risk reduction. Take the reciprocal of this (ie, 1 divided by this number) to get the number needed to treat.

Describing risks in absolute terms or using number needed to treat (or harm) can help conceptualize statistics that are sometimes hard to wrap your head around.

 

4. Dessert — Funding

By the time the coffee is served, everyone will be hanging on to your every word. This is as it should be, and you should not be afraid of your newfound power and influence. 

Dessert will probably involve some form of chocolate, possibly in cake format. (Anyone who serves fruit as dessert is not someone you should associate with.) Take the opportunity to tell your follow diners that chocolate is not actually good for you and will not boost brain performance.

The health benefits of chocolate are often repeated but rarely scrutinized. In fact, much of the scientific research purporting to show that chocolate is good for you did not actually study chocolate. It usually involved a cocoa bean extract because the chocolate manufacturing process destroys the supposedly health-promoting antioxidants in the cocoa bean. It is true that dark chocolate has more antioxidants than milk chocolate, and that the addition of milk to chocolate further inactivates the potentially healthy antioxidants. But the amount of sugar and fat that has to be added to chocolate to make it palatable precludes any serious consideration about health benefits. Dark chocolate may have less fat and sugar than milk chocolate, but it still has a lot.

But even the cocoa bean extract doesn’t seem to do much for your heart or your brain. The long-awaited COSMOS study was published with surprisingly little fanfare. The largest randomized controlled trial of chocolate (or rather cocoa bean extract) was supposed to settle the issue definitively.

COSMOS showed no cardiovascular or neurocognitive benefit to the cocoa bean extract. But the health halo of chocolate continues to be bolstered by many studies funded by chocolate manufacturers. 

We are appropriately critical of the pharmaceutical industry’s involvement in drug research. However, we should not forget that any private entity is prone to the same self-interest regardless of its product’s tastiness. How many of you knew that there was an avocado lobby funding research? No matter how many industry-funded observational studies using surrogate endpoints are out there telling you that chocolate is healthy, a randomized trial with hard clinical endpoints such as COSMOS should generally win the day.

 

The Final Goodbyes — Summarizing Your Case

As the party slowly winds down and everyone is saddened that you will soon take your leave, synthesize everything you have taught them over the evening. Like movies, not all studies are good. Some are just bad. They can be prone to reverse causation or confounding, and they may report relative risks when absolute risks would be more telling. Reading research studies critically is essential for separating the wheat from the chaff. With the knowledge you have now imparted to your friends, they will be much better consumers of medical news, especially when it comes to food. 

And they will no doubt thank you for it by never inviting you to another dinner party!

Labos, a cardiologist at Hôpital, Notre-Dame, Montreal, Quebec, Canada, has disclosed no relevant financial relationships. He has a degree in epidemiology.

A version of this article appeared on Medscape.com.

But even the cocoa bean extract doesn’t seem to do much for your heart or your brain. The long-awaited COSMOS study was published with surprisingly little fanfare. The largest randomized controlled trial of chocolate (or rather cocoa bean extract) was supposed to settle the issue definitively.

COSMOS showed no cardiovascular or neurocognitive benefit to the cocoa bean extract. But the health halo of chocolate continues to be bolstered by many studies funded by chocolate manufacturers. 

We are appropriately critical of the pharmaceutical industry’s involvement in drug research. However, we should not forget that any private entity is prone to the same self-interest regardless of its product’s tastiness. How many of you knew that there was an avocado lobby funding research? No matter how many industry-funded observational studies using surrogate endpoints are out there telling you that chocolate is healthy, a randomized trial with hard clinical endpoints such as COSMOS should generally win the day.

 

The Final Goodbyes — Summarizing Your Case

As the party slowly winds down and everyone is saddened that you will soon take your leave, synthesize everything you have taught them over the evening. Like movies, not all studies are good. Some are just bad. They can be prone to reverse causation or confounding, and they may report relative risks when absolute risks would be more telling. Reading research studies critically is essential for separating the wheat from the chaff. With the knowledge you have now imparted to your friends, they will be much better consumers of medical news, especially when it comes to food. 

And they will no doubt thank you for it by never inviting you to another dinner party!

You’re invited to a dinner party but you struggle to make small talk. Do not worry; you can use your knowledge of study design and epidemiology to impress people with your savoir faire regarding popular food myths that will invariably crop up over cocktails. Because all journalism has been reduced to listicles, here are four ways to seem clever at dinner parties.

1. The Predinner Cocktails: A Lesson in Reverse Causation

Wine connoisseurs sniff, swirl, and gently swish the wine in their mouths before spitting out and cleansing their palates to better appreciate the subtlety of each vintage. If you’re not an oenophile, no matter. Whenever somebody claims that moderate amounts of alcohol are good for your heart, this is your moment to pounce. Interject yourself in the conversation and tell everybody about reverse causation.

Reverse causation, also known as protopathic bias, involves misinterpreting the directionality of an association. You assume that X leads to Y, when in fact Y leads to X. Temporal paradoxes are useful plot devices in science fiction movies, but they have no place in medical research. In our bland world, cause must precede effect. As such, smoking leads to lung cancer; lung cancer doesn’t make you smoke more. 

But with alcohol, directionality is less obvious. Many studies of alcohol and cardiovascular disease have demonstrated a U-shaped association, with risk being lowest among those who drink moderate amounts of alcohol (usually one to two drinks per day) and higher in those who drink more and also those who drink very little.

But one must ask why some people drink little or no alcohol. There is an important difference between former drinkers and never drinkers. Former drinkers cut back for a reason. More likely than not, the reason for this newfound sobriety was medical. A new cancer diagnosis, the emergence of atrial fibrillation, the development of diabetes, or rising blood pressure are all good reasons to reduce or eliminate alcohol. A cross-sectional study will fail to capture that alcohol consumption changes over time — people who now don’t drink may have imbibed alcohol in years past. It was not abstinence that led to an increased risk for heart disease; it was the increased risk for heart disease that led to abstinence.

You see the same phenomenon with the so-called obesity paradox. The idea that being a little overweight is good for you may appeal when you no longer fit into last year’s pants. But people who are underweight are so for a reason. Malnutrition, cachexia from cancer, or some other cause is almost certainly driving up the risk at the left-hand side of the U-shaped curve that makes the middle part seem better than it actually is.

Food consumption changes over time. A cross-sectional survey at one point in time cannot accurately capture past habits and distant exposures, especially for diseases such as heart disease and cancer that develop slowly over time. Studies on alcohol that try to overcome these shortcomings by eliminating former drinkers, or by using Mendelian randomization to better account for past exposure, do not show a cardiovascular benefit for moderate red wine drinking.

 

2. The Hors D’oeuvres — The Importance of RCTs

Now that you have made yourself the center of attention, it is time to cement your newfound reputation as a font of scientific knowledge. Most self-respecting hosts will serve smoked salmon as an amuse-bouche before the main meal. When someone mentions the health benefits of fish oils, you should take the opportunity to teach them about confounding.

Fish, especially cold-water fish from northern climates, have relatively high amounts of omega-3 fatty acids. Despite the plethora of observational studies suggesting a cardiovascular benefit, it’s now relatively clear that fish oil or omega-3 supplements have no medical benefit.

This will probably come as a shock to the worried well, but many studies, including VITAL and ASCEND, have demonstrated no cardiovascular or cancer benefit to supplementation with omega-3s. The reason is straightforward and explains why hormone replacement therapy, vitamin D, and myriad purported game-changers never panned out. Confounding is hard to overcome in observational research.

Prior to the publication of the Women’s Health Initiative (WHI) Study, hormone replacement therapy was routinely prescribed to postmenopausal women because numerous observational studies suggested a cardiovascular benefit. But with the publication of the WHI study, it became clear that much of that “benefit” was due to confounding. The women choosing to take hormones were more health conscious at baseline and healthier overall. 

A similar phenomenon occurred during COVID. Patients with low serum vitamin D levels had worse outcomes, prompting many to suggest vitamin D supplementation as a possible treatment. Trials did not support the intervention because we’d overlooked the obvious. People with vitamin D deficiency have underlying health problems that contribute to the vitamin D deficiency. They are probably older, frailer, possibly with a poorer diet. No amount of statistical adjustment can account for all those differences, and some degree of residual confounding will always persist.

The only way to overcome confounding is with randomization. When patients are randomly assigned to one group or another, their baseline differences largely balance out if the randomization was performed properly and the groups were large enough. There is a role for observational research, such as in situations where ethics, cost, and practicality do not allow for a randomized controlled trial. But randomized controlled trials have largely put to rest the purported health benefits of over-the-counter fish oils, omega-3s, and vitamin D.

 

3. The Main Course — Absolute vs Relative Risk

When you get to the main course, all eyes will now be on you. You will almost certainly be called upon to pronounce on the harms or benefits of red meat consumption. Begin by regaling your guests with a little trivia. Ask them if they know the definition of red meat and white meat. When someone says pork is white meat, you can reveal that “pork, the other white meat,” was a marketing slogan with no scientific underpinning. Now that everyone is lulled into a stupefied silence, tell them that red meat comes from mammals and white meat comes from birds. As they process this revelation, you can now launch into the deeply mathematical concept of absolute vs relative risk.

Many etiquette books will caution against bringing up math at a dinner party. These books are wrong. Everyone finds math interesting if they are primed properly. For example, you can point to a study claiming that berries reduce cardiovascular risk in women. Even if true — and there is reason to be cautious, given the observational nature of the research — we need to understand what the authors meant by a 32% risk reduction. (Side note: It was a reduction in hazard, with a hazard ratio of 0.68 (95% CI, 0.49-0.96), but we won’t dwell on the difference between hazard ratios and risk ratios right now.)

This relative risk reduction has to be interpreted carefully. The authors divided the population into quintiles based on their consumption of anthocyanins (the antioxidant in blueberries and strawberries) and compared the bottom fifth (average consumption, 2.5 mg/d) with the top fifth (average consumption, 25 mg/d). The bottom quintile had 126 myocardial infarctions (MIs) over 324,793 patient-years compared with 59 MIs over 332,143 patient-years. Some quick math shows an approximate reduction from 39 to 18 MIs per 100,000 patient-years. Or to put it another way, you must get 4762 women to increase their berry consumption 10-fold for 1 year to prevent one heart attack. Feel free to show people how you calculated this number. They will be impressed by your head for numbers. It is nothing more than 39 minus 18, divided by 100,000, to get the absolute risk reduction. Take the reciprocal of this (ie, 1 divided by this number) to get the number needed to treat.

Describing risks in absolute terms or using number needed to treat (or harm) can help conceptualize statistics that are sometimes hard to wrap your head around.

 

4. Dessert — Funding

By the time the coffee is served, everyone will be hanging on to your every word. This is as it should be, and you should not be afraid of your newfound power and influence. 

Dessert will probably involve some form of chocolate, possibly in cake format. (Anyone who serves fruit as dessert is not someone you should associate with.) Take the opportunity to tell your follow diners that chocolate is not actually good for you and will not boost brain performance.

The health benefits of chocolate are often repeated but rarely scrutinized. In fact, much of the scientific research purporting to show that chocolate is good for you did not actually study chocolate. It usually involved a cocoa bean extract because the chocolate manufacturing process destroys the supposedly health-promoting antioxidants in the cocoa bean. It is true that dark chocolate has more antioxidants than milk chocolate, and that the addition of milk to chocolate further inactivates the potentially healthy antioxidants. But the amount of sugar and fat that has to be added to chocolate to make it palatable precludes any serious consideration about health benefits. Dark chocolate may have less fat and sugar than milk chocolate, but it still has a lot.

But even the cocoa bean extract doesn’t seem to do much for your heart or your brain. The long-awaited COSMOS study was published with surprisingly little fanfare. The largest randomized controlled trial of chocolate (or rather cocoa bean extract) was supposed to settle the issue definitively.

COSMOS showed no cardiovascular or neurocognitive benefit to the cocoa bean extract. But the health halo of chocolate continues to be bolstered by many studies funded by chocolate manufacturers. 

We are appropriately critical of the pharmaceutical industry’s involvement in drug research. However, we should not forget that any private entity is prone to the same self-interest regardless of its product’s tastiness. How many of you knew that there was an avocado lobby funding research? No matter how many industry-funded observational studies using surrogate endpoints are out there telling you that chocolate is healthy, a randomized trial with hard clinical endpoints such as COSMOS should generally win the day.

A version of this article appeared on Medscape.com.

I’m just back from the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting in Philadelphia, Pennsylvania. 

In part 2 of this series, I’m offering my highlights from this year’s meeting. (Part 1 is available here.) They are not presented in any particular order, but instead I am sharing what I found to be the most exciting among the thousands of abstracts and presentations. 

 

Performing Capsule Endoscopy in Patients Taking GLP-1s 

We’ve heard a lot about glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and the possibility that they might contribute to an increased risk for retained gastric contents and aspiration during endoscopy.

In the first study I’d like to highlight, researchers from the Mayo Clinic in Jacksonville, Florida, investigated video capsule endoscopy in patients with diabetes who were taking GLP-1 RAs vs a control group with diabetes not taking GLP-1 Ras. Patients in this retrospective matched cohort study were well balanced for demographics and diabetes-related characteristics.

Researchers found that in 7% of the 68 patients in the GLP-1 RA cohort, the video capsule endoscopy actually failed to pass through the stomach, whereas it passed successfully in all 68 patients in the control group (P =.06). The GLP-1 RA cohort had a longer transit time by a factor of almost four times (P <.001).

Multivariate analysis also showed that gastric transit time was approximately 80 minutes longer in the GLP-1 RA cohort (P <.001). Interestingly, 23.5% (16 of 68 patients) in the GLP-1 RA group experienced incomplete passage of the video capsule endoscopy through the small intestine, which was significantly higher than the proportion observed in the control group (4.4%; P <.01). 

We need to look at potential strategies to mitigate these effects. Be aware of these results as you perform capsule endoscopy in patients taking GLP-1 RAs. 

 

Barrett Esophagus On the Rise in the Young 

The second study that caught my eye revealed the increasing incidence of young-onset Barrett esophagus (BE).

This population-based study used data obtained from TriNetX, a multi-institutional national database that offers a composite of health records from 88 healthcare organizations. Eligible patients had to have a negative upper esophagogastroduodenoscopy for BE prior to subsequently developing BE. Researchers stratified patients as to whether they were younger (< 50 years) or older (≥ 50 years), with further age ranges analyzed within those groups. 

Young-onset BE accounted for 20% of all incident cases. The majority (94%) had nondysplastic BE. The incidence rate was not significantly different depending on whether patients were in the 45- to 49-year or 50- to 54-year age group. 

Regression analysis revealed that there was a significantly increased trend for young-onset BE with hiatal hernia (odds ratio [OR], 2.6), smoking (OR, 2.3), White race (OR, 2.3), obstructive sleep apnea (OR, 2.2), male gender (OR, 2.0), and — at relatively lower risk levels — gastroesophageal reflux disease symptoms (OR, 1.2) and body mass index (OR, 1.1). The researchers did not analyze patients based on the presence of obesity, which is one of the risk factors for BE mentioned in national guidelines.

Results also showed that 6% of those with young-onset BE had BE-related neoplasia. 

ACG guidelines recommend screening for BE beginning at age 50 in those with some of the risk factors noted in this study, including the presence of chronic gastroesophageal reflux disease symptoms. However, doing so may not capture the growing number of patients with young-onset BE. 

We’ve seen a similar rise in rates of young-onset colorectal cancer, which has caused us to reevaluate our screening methods. Maybe we should do this for BE as well, specifically for patients presenting with these risk factors. 

There’s a caveat to be aware of, which comes from my personal experience. I was biopsied for short-segment BE, and because it came up on my health record, it increased my life insurance premiums. This was because I was identified as having the risk profile of, essentially, an otherwise healthy smoker. 

Dr Nicholas J. Shaheen and colleagues published a study several years ago showing that many insurance companies would not certify young, otherwise healthy people once diagnosed with BE. This is something to be aware of when you start to screen for BE, especially among younger patients.

 

A Novel Biologic for Eosinophilic Esophagitis 

The next study presented results from a randomized, placebo-controlled, phase 3 study of cendakimab, a biologic agent in development for the treatment of eosinophilic esophagitis (EoE).

Dupilumab, which is an anti–interleukin (IL)-4 antibody, is the first treatment approved by the US Food and Drug Administration (FDA) for the treatment of EoE. Cendakimab, in turn, is a monoclonal antibody that neutralizes IL-13, a cytokine that plays a key role in EoE. 

The study was led by Dr Evan Dellon from the University of North Carolina at Chapel Hill. Dellon and colleagues analyzed two different dosing regimens of cendakimab — 360 mg once weekly for 48 weeks, or 360 mg once weekly for 24 weeks followed by 360 mg every other week for 24 weeks — vs placebo for 48 weeks. 

There was a significant effect for both cendakimab regimens in terms of symptom improvement and histologic response. There wasn’t much difference between participants that maintained once-weekly dosing and those who switched over to receive cendakimab every other week at 24 weeks. Only a minimal number of serious adverse events leading to discontinuation were noted in the study, with no notable difference between the treatment groups. 

I think we’ll probably see this drug become available to us soon after it goes through the FDA review process, at which point it will add to our ability to use formative biologics in patients with EoE.

 

No Clear Benefit to Adding Bezlotoxumab to Fecal Microbiota Transplantation 

Next was a very interesting study, and I think a clinically relevant one, about using fecal microbiota transplantation (FMT) alone or in combination with bezlotoxumab in patients with inflammatory bowel disease (IBD) with recurrent Clostridioides difficile infection.

Bezlotoxumab is a fully human monoclonal antibody that binds to C difficile toxin B. This drug has been studied and is approved for use, but it’s also extremely expensive, at a cost of approximately $4000 per dose. 

Patients with IBD were eligible for inclusion if they had had two or more episodes of C difficile infection. They were then randomized in a 1:1 ration to receive either a single infusion of bezlotoxumab or placebo prior to FMT. The primary endpoint was C difficile infection recurrence within 8 weeks, which was defined as diarrhea plus a positive enzyme immunoassay toxin test. The secondary outcome was C difficile decolonization following treatment. 

Researchers observed no statistically significant difference between the two cohorts. Steroid use prior to FMT significantly increased the risk for ongoing C difficile colonization (P =.03). 

In summary, this is a case where it doesn’t seem that more is better. Bezlotoxumab didn’t add much, which calls into question the justification for its combined use with FMT. 

 

Additional Positive Data for Seladelpar in Primary Biliary Cholangitis and Cirrhosis 

Reassuring findings were presented on seladelpar, which was granted accelerated approval by the FDA in August. 

Seladelpar is a selective peroxisome proliferator–activated receptor delta agonist that works in biliary cholangitis by regulating the genes involved in blocking biliary bile acid synthesis and controlling inflammation and fibrosis. 

Results from the phase 3 RESPONSE trial were published in The New England Journal of Medicine in February reporting on the use of seladelpar in primary biliary cholangitis.

Whereas the RESPONSE trial removed decompensated patients, the ongoing phase 3 ASSURE trial results presented at this year’s meeting included patients with compensated cirrhosis. Approximately 94% of the patients in this study had Child-Pugh class A and 6% had class B cirrhosis. Eligibility required that patients had an inadequate response or were intolerant to ursodeoxycholic acid. Patients were administered open-label seladelpar 10 mg orally daily and followed for up to 1 year.

The good news is that there were no safety signals, which is reassuring news for our patients with compensated cirrhosis. 

 

Advantages to Respiratory Syncytial Virus Vaccination in IBD 

Another study that offered results certainly worthy of attention dealt with vaccination recommendations in patients with IBD. 

Vaccination for respiratory syncytial virus (RSV) is now available in the United States. Its use was recommended for patients with IBD as early as 2021 per the Canadian Association of Gastroenterology’s clinical practice guideline, which discusses both live and nonlive vaccines. We should be aggressive in recommending this vaccine to our patients with IBD, but we haven’t really had one until recently. 

Researchers behind this retrospective cohort study used the TriNetX database, which includes over 100 million unique patient charts. They identified patients with IBD, who were then divided into two groups according to whether they received the RSV vaccine or not. 

Although this analysis was conducted in patients > 60 years of age, the US Centers for Disease Control and Prevention recommends RSV vaccination for all those over the age of 75 years, as well as for those 60-74 years old based on severity of risk. 

For the primary endpoint of risk for RSV pneumonia, the OR was dramatically better in those who were vaccinated, with an approximately 80% risk reduction. Additionally, vaccinated patients experienced risk reductions of approximately 60% for acute respiratory failure, 50% for hospital inpatient admission, and 70% for requiring intensive care unit services. 

This is a strong study showing not only that RSV vaccine did not exacerbate IBD but also that it improved outcomes in these patients. There’s a live-attenuated RSV vaccination that’s administered intranasally, which wouldn’t be used in your biologic or immunosuppressed patients with IBD, but the intramuscularly administered RSV vaccine doesn’t have any risk.

I think we can immediately begin recommending the RSV vaccine for our patients with IBD, particularly in those 60 years of age or older.

 

The Impact of Palliative Care Consultations in Decompensated Cirrhosis 

The next study I’d like to highlight offers important data on the impact of palliative care consultation on 30- and 90-day readmission in patients with decompensated cirrhosis, which is a major cause of morbidity and mortality.

Researchers queried the National Readmissions Database over a 10-year period (2010-2019) to determine whether patients received a palliative care consult during index admission. They drew on a population of over 1.6 million patients admitted with decompensated cirrhosis. 

Of this group, only 7.4% received a palliative care consultation at the index admission. But if they had this consultation, it was associated with a dramatic effect on readmission at 30 and 90 days. There was statistically significant risk reduction of approximately 70% for both 30- and 90-day readmission compared with those who didn’t receive the palliative consult (P <.001).

The take-home message here is to get a palliative care consult with these patients when they come in. Your hospital will unquestionably experience value in this reduction in readmission, especially considering that readmission within 30 days may not even be covered. Look at these results and start to take advantage of this valuable consultation.

 

Auxora: A Novel Treatment for Acute Pancreatitis 

The last study for discussion offered very interesting data related to a drug called Auxora, a calcium release–activated calcium-channel inhibitor.

There is growing data that overactive calcium release–activated calcium channels aggravate acute pancreatitis and accelerate systemic inflammatory response syndrome (SIRS).

Acute pancreatitis with necrosis encompasses both local and systemic inflammation and is associated with significant mortality and morbidity. It is estimated that among patients with acute pancreatitis, 20%-30% have pancreatic necrosis, 30% develop infection, and 25% develop organ failure. 

The presence of SIRS seems to herald the activation of these complex inflammatory pathways, which then leads to organ failure and necrosis, which can potentially be stemmed through this calcium channel inhibitor. Phase 2 studies of Auxora found that its use was associated with significant reduction in the risk for progression.

This subsequent phase 3 study looked at patients with acute pancreatitis and accompanying grade ≥ 2 SIRS criteria. They were randomized to receive placebo or Auxora at doses of 2 mg/kg, 1 mg/kg, or 0.5 mg/kg, which was administered intravenously over 4 hours for 3 consecutive days. 

The primary endpoint was time to solid food tolerance, which was defined as eating ≥ 50% of a ≥ 500-calorie low-fat solid meal without increased abdominal pain or emesis, which is an important target because we always aim for enteral nutrition in patients with acute pancreatitis. The key secondary endpoint was severe respiratory failure, which was defined as invasive mechanical ventilation or ≥ 48 hours of either high-flow nasal cannula or noninvasive mechanical ventilation. 

The primary endpoint was dramatically improved among those receiving Auxora, who achieved early onset of refeed. It appears that the high-dose 2 mg/kg may be the most beneficial in achieving improvement. 

There were no patients with suspected or unexpected adverse events in the study population. Additionally, no patients receiving Auxora at any dose level went on to develop respiratory failure. 

The present results show that Auxora decreases the time for solid food tolerance, as well as the rates of respiratory failure and necrotizing pancreatitis in patients presenting with two or more SIRS criteria. We’ll certainly look forward to more data, but it provides hope for a new treatment for acute pancreatitis.

There were lots of intriguing data presented at ACG 2024. Obviously, we’d like to see them evolve in subsequent journal manuscripts. 

Some of the take-home messages I presented are actionable now, whereas for others, we’ll have to wait and see what the final data show as well as the results of ongoing FDA approval before applying them.

Patients were administered open-label seladelpar 10 mg orally daily and followed for up to 1 year.

The good news is that there were no safety signals, which is reassuring news for our patients with compensated cirrhosis. 

 

Advantages to Respiratory Syncytial Virus Vaccination in IBD 

Another study that offered results certainly worthy of attention dealt with vaccination recommendations in patients with IBD. 

Vaccination for respiratory syncytial virus (RSV) is now available in the United States. Its use was recommended for patients with IBD as early as 2021 per the Canadian Association of Gastroenterology’s clinical practice guideline, which discusses both live and nonlive vaccines. We should be aggressive in recommending this vaccine to our patients with IBD, but we haven’t really had one until recently. 

Researchers behind this retrospective cohort study used the TriNetX database, which includes over 100 million unique patient charts. They identified patients with IBD, who were then divided into two groups according to whether they received the RSV vaccine or not. 

Although this analysis was conducted in patients > 60 years of age, the US Centers for Disease Control and Prevention recommends RSV vaccination for all those over the age of 75 years, as well as for those 60-74 years old based on severity of risk. 

For the primary endpoint of risk for RSV pneumonia, the OR was dramatically better in those who were vaccinated, with an approximately 80% risk reduction. Additionally, vaccinated patients experienced risk reductions of approximately 60% for acute respiratory failure, 50% for hospital inpatient admission, and 70% for requiring intensive care unit services. 

This is a strong study showing not only that RSV vaccine did not exacerbate IBD but also that it improved outcomes in these patients. There’s a live-attenuated RSV vaccination that’s administered intranasally, which wouldn’t be used in your biologic or immunosuppressed patients with IBD, but the intramuscularly administered RSV vaccine doesn’t have any risk.

I think we can immediately begin recommending the RSV vaccine for our patients with IBD, particularly in those 60 years of age or older.

 

The Impact of Palliative Care Consultations in Decompensated Cirrhosis 

The next study I’d like to highlight offers important data on the impact of palliative care consultation on 30- and 90-day readmission in patients with decompensated cirrhosis, which is a major cause of morbidity and mortality.

Researchers queried the National Readmissions Database over a 10-year period (2010-2019) to determine whether patients received a palliative care consult during index admission. They drew on a population of over 1.6 million patients admitted with decompensated cirrhosis. 

Of this group, only 7.4% received a palliative care consultation at the index admission. But if they had this consultation, it was associated with a dramatic effect on readmission at 30 and 90 days. There was statistically significant risk reduction of approximately 70% for both 30- and 90-day readmission compared with those who didn’t receive the palliative consult (P <.001).

The take-home message here is to get a palliative care consult with these patients when they come in. Your hospital will unquestionably experience value in this reduction in readmission, especially considering that readmission within 30 days may not even be covered. Look at these results and start to take advantage of this valuable consultation.

 

Auxora: A Novel Treatment for Acute Pancreatitis 

The last study for discussion offered very interesting data related to a drug called Auxora, a calcium release–activated calcium-channel inhibitor.

There is growing data that overactive calcium release–activated calcium channels aggravate acute pancreatitis and accelerate systemic inflammatory response syndrome (SIRS).

Acute pancreatitis with necrosis encompasses both local and systemic inflammation and is associated with significant mortality and morbidity. It is estimated that among patients with acute pancreatitis, 20%-30% have pancreatic necrosis, 30% develop infection, and 25% develop organ failure. 

The presence of SIRS seems to herald the activation of these complex inflammatory pathways, which then leads to organ failure and necrosis, which can potentially be stemmed through this calcium channel inhibitor. Phase 2 studies of Auxora found that its use was associated with significant reduction in the risk for progression.

This subsequent phase 3 study looked at patients with acute pancreatitis and accompanying grade ≥ 2 SIRS criteria. They were randomized to receive placebo or Auxora at doses of 2 mg/kg, 1 mg/kg, or 0.5 mg/kg, which was administered intravenously over 4 hours for 3 consecutive days. 

The primary endpoint was time to solid food tolerance, which was defined as eating ≥ 50% of a ≥ 500-calorie low-fat solid meal without increased abdominal pain or emesis, which is an important target because we always aim for enteral nutrition in patients with acute pancreatitis. The key secondary endpoint was severe respiratory failure, which was defined as invasive mechanical ventilation or ≥ 48 hours of either high-flow nasal cannula or noninvasive mechanical ventilation. 

The primary endpoint was dramatically improved among those receiving Auxora, who achieved early onset of refeed. It appears that the high-dose 2 mg/kg may be the most beneficial in achieving improvement. 

There were no patients with suspected or unexpected adverse events in the study population. Additionally, no patients receiving Auxora at any dose level went on to develop respiratory failure. 

The present results show that Auxora decreases the time for solid food tolerance, as well as the rates of respiratory failure and necrotizing pancreatitis in patients presenting with two or more SIRS criteria. We’ll certainly look forward to more data, but it provides hope for a new treatment for acute pancreatitis.

There were lots of intriguing data presented at ACG 2024. Obviously, we’d like to see them evolve in subsequent journal manuscripts. 

Some of the take-home messages I presented are actionable now, whereas for others, we’ll have to wait and see what the final data show as well as the results of ongoing FDA approval before applying them.

I’m just back from the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting in Philadelphia, Pennsylvania. 

In part 2 of this series, I’m offering my highlights from this year’s meeting. (Part 1 is available here.) They are not presented in any particular order, but instead I am sharing what I found to be the most exciting among the thousands of abstracts and presentations. 

 

Performing Capsule Endoscopy in Patients Taking GLP-1s 

We’ve heard a lot about glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and the possibility that they might contribute to an increased risk for retained gastric contents and aspiration during endoscopy.

In the first study I’d like to highlight, researchers from the Mayo Clinic in Jacksonville, Florida, investigated video capsule endoscopy in patients with diabetes who were taking GLP-1 RAs vs a control group with diabetes not taking GLP-1 Ras. Patients in this retrospective matched cohort study were well balanced for demographics and diabetes-related characteristics.

Researchers found that in 7% of the 68 patients in the GLP-1 RA cohort, the video capsule endoscopy actually failed to pass through the stomach, whereas it passed successfully in all 68 patients in the control group (P =.06). The GLP-1 RA cohort had a longer transit time by a factor of almost four times (P <.001).

Multivariate analysis also showed that gastric transit time was approximately 80 minutes longer in the GLP-1 RA cohort (P <.001). Interestingly, 23.5% (16 of 68 patients) in the GLP-1 RA group experienced incomplete passage of the video capsule endoscopy through the small intestine, which was significantly higher than the proportion observed in the control group (4.4%; P <.01). 

We need to look at potential strategies to mitigate these effects. Be aware of these results as you perform capsule endoscopy in patients taking GLP-1 RAs. 

 

Barrett Esophagus On the Rise in the Young 

The second study that caught my eye revealed the increasing incidence of young-onset Barrett esophagus (BE).

This population-based study used data obtained from TriNetX, a multi-institutional national database that offers a composite of health records from 88 healthcare organizations. Eligible patients had to have a negative upper esophagogastroduodenoscopy for BE prior to subsequently developing BE. Researchers stratified patients as to whether they were younger (< 50 years) or older (≥ 50 years), with further age ranges analyzed within those groups. 

Young-onset BE accounted for 20% of all incident cases. The majority (94%) had nondysplastic BE. The incidence rate was not significantly different depending on whether patients were in the 45- to 49-year or 50- to 54-year age group. 

Regression analysis revealed that there was a significantly increased trend for young-onset BE with hiatal hernia (odds ratio [OR], 2.6), smoking (OR, 2.3), White race (OR, 2.3), obstructive sleep apnea (OR, 2.2), male gender (OR, 2.0), and — at relatively lower risk levels — gastroesophageal reflux disease symptoms (OR, 1.2) and body mass index (OR, 1.1). The researchers did not analyze patients based on the presence of obesity, which is one of the risk factors for BE mentioned in national guidelines.

Results also showed that 6% of those with young-onset BE had BE-related neoplasia. 

ACG guidelines recommend screening for BE beginning at age 50 in those with some of the risk factors noted in this study, including the presence of chronic gastroesophageal reflux disease symptoms. However, doing so may not capture the growing number of patients with young-onset BE. 

We’ve seen a similar rise in rates of young-onset colorectal cancer, which has caused us to reevaluate our screening methods. Maybe we should do this for BE as well, specifically for patients presenting with these risk factors. 

There’s a caveat to be aware of, which comes from my personal experience. I was biopsied for short-segment BE, and because it came up on my health record, it increased my life insurance premiums. This was because I was identified as having the risk profile of, essentially, an otherwise healthy smoker. 

Dr Nicholas J. Shaheen and colleagues published a study several years ago showing that many insurance companies would not certify young, otherwise healthy people once diagnosed with BE. This is something to be aware of when you start to screen for BE, especially among younger patients.

 

A Novel Biologic for Eosinophilic Esophagitis 

The next study presented results from a randomized, placebo-controlled, phase 3 study of cendakimab, a biologic agent in development for the treatment of eosinophilic esophagitis (EoE).

Dupilumab, which is an anti–interleukin (IL)-4 antibody, is the first treatment approved by the US Food and Drug Administration (FDA) for the treatment of EoE. Cendakimab, in turn, is a monoclonal antibody that neutralizes IL-13, a cytokine that plays a key role in EoE. 

The study was led by Dr Evan Dellon from the University of North Carolina at Chapel Hill. Dellon and colleagues analyzed two different dosing regimens of cendakimab — 360 mg once weekly for 48 weeks, or 360 mg once weekly for 24 weeks followed by 360 mg every other week for 24 weeks — vs placebo for 48 weeks. 

There was a significant effect for both cendakimab regimens in terms of symptom improvement and histologic response. There wasn’t much difference between participants that maintained once-weekly dosing and those who switched over to receive cendakimab every other week at 24 weeks. Only a minimal number of serious adverse events leading to discontinuation were noted in the study, with no notable difference between the treatment groups. 

I think we’ll probably see this drug become available to us soon after it goes through the FDA review process, at which point it will add to our ability to use formative biologics in patients with EoE.

 

No Clear Benefit to Adding Bezlotoxumab to Fecal Microbiota Transplantation 

Next was a very interesting study, and I think a clinically relevant one, about using fecal microbiota transplantation (FMT) alone or in combination with bezlotoxumab in patients with inflammatory bowel disease (IBD) with recurrent Clostridioides difficile infection.

Bezlotoxumab is a fully human monoclonal antibody that binds to C difficile toxin B. This drug has been studied and is approved for use, but it’s also extremely expensive, at a cost of approximately $4000 per dose. 

Patients with IBD were eligible for inclusion if they had had two or more episodes of C difficile infection. They were then randomized in a 1:1 ration to receive either a single infusion of bezlotoxumab or placebo prior to FMT. The primary endpoint was C difficile infection recurrence within 8 weeks, which was defined as diarrhea plus a positive enzyme immunoassay toxin test. The secondary outcome was C difficile decolonization following treatment. 

Researchers observed no statistically significant difference between the two cohorts. Steroid use prior to FMT significantly increased the risk for ongoing C difficile colonization (P =.03). 

In summary, this is a case where it doesn’t seem that more is better. Bezlotoxumab didn’t add much, which calls into question the justification for its combined use with FMT. 

 

Additional Positive Data for Seladelpar in Primary Biliary Cholangitis and Cirrhosis 

Reassuring findings were presented on seladelpar, which was granted accelerated approval by the FDA in August. 

Seladelpar is a selective peroxisome proliferator–activated receptor delta agonist that works in biliary cholangitis by regulating the genes involved in blocking biliary bile acid synthesis and controlling inflammation and fibrosis. 

Results from the phase 3 RESPONSE trial were published in The New England Journal of Medicine in February reporting on the use of seladelpar in primary biliary cholangitis.

Whereas the RESPONSE trial removed decompensated patients, the ongoing phase 3 ASSURE trial results presented at this year’s meeting included patients with compensated cirrhosis. Approximately 94% of the patients in this study had Child-Pugh class A and 6% had class B cirrhosis. Eligibility required that patients had an inadequate response or were intolerant to ursodeoxycholic acid. Patients were administered open-label seladelpar 10 mg orally daily and followed for up to 1 year.

The good news is that there were no safety signals, which is reassuring news for our patients with compensated cirrhosis. 

 

Advantages to Respiratory Syncytial Virus Vaccination in IBD 

Another study that offered results certainly worthy of attention dealt with vaccination recommendations in patients with IBD.

Its use was recommended for patients with IBD as early as 2021 per the Canadian Association of Gastroenterology’s clinical practice guideline, which discusses both live and nonlive vaccines.

Additionally, vaccinated patients experienced risk reductions of approximately 60% for acute respiratory failure, 50% for hospital inpatient admission, and 70% for requiring intensive care unit services.

I think we can immediately begin recommending the RSV vaccine for our patients with IBD, particularly in those 60 years of age or older.

The next study I’d like to highlight offers important data on the impact of palliative care consultation on 30- and 90-day readmission in patients with decompensated cirrhosis, which is a major cause of morbidity and mortality.

VANCOUVER, BRITISH COLUMBIA — Conditions like diabetes and dementia are common in patients who are admitted to long-term care facilities, but aggressive management of these conditions in long-term care residents is not recommended, according to a presentation given at the Family Medicine Forum (FMF) 2024.

Hospitalizations for hypoglycemia are risky for patients with diabetes who are residents of long-term care facilities, particularly those aged 75 years or older, said Adam Gurau, MD, a family physician in Toronto. Gurau completed a fellowship in care of the elderly at the University of Toronto, in Ontario, Canada.

“A lot of studies have shown diabetes-related hospitalizations,” said Gurau. He cited a 2014 study that found that hypoglycemia hospitalization rates were twice as high in older patients (age, 75 years or older) as in younger patients (age, 65-74 years).

“It is important to keep in mind that our residents in long-term care are at increasing risk for hypoglycemia, and we really should try to reduce [this risk] and not use dangerous medications or potentially dangerous [means of] diabetes management,” said Gurau.

A Canadian study that examined the composite risk for emergency department visits, hospitalizations, or death within 30 days of reaching intensive glycemic control with high-risk agents (such as insulin or sulfonylureas) suggested little benefit and possible harm in using these agents in adults aged 75 years or older.

In addition, current guidelines on diabetes management encourage a different approach. “Looking at some of the more recent North American guidelines, many of them actually now recommend relaxing glycemic targets to reduce overtreatment and prevent hypoglycemia,” said Gurau.

 

Deprescribing Medications

Medication reviews present opportunities for taking a global view of a patient’s treatments and determining whether any drug can be removed from the list. “What we want to do is optimize medications,” said Gurau. “We’re not talking about adding medications. We’re talking about removing medications, which is, I think, what we should be doing.”

Some research suggests that patients are open to deprescribing. One survey examined older adults (mean age, 79.1 years) with three or more chronic conditions who had been prescribed at least five medications. The researchers found that most participants (77%) were willing to deprescribe one or more medicines if a doctor advised that it was possible. “General practitioners may be able to increase deprescribing by building trust with their patients and communicating evidence about the risks of medication use,” the researchers wrote.

About 62% of seniors living in a residential care home have a diagnosis of Alzheimer’s disease or another dementia, according to the Alzheimer Society of Canada. Evidence suggests that nonpharmacologic approaches, such as massage and touch therapy and music, can manage neuropsychiatric symptoms, such as aggression and agitation, that are associated with dementia in older adults, noted Gurau.

“We want to focus on nonpharmacologic approaches for many of these [long-term care] residents,” said Gurau. “We have to do as much as we can to exhaust all the nonpharmacologic approaches.”

 

Preventing Hospitalizations

Another challenge to tackle in long-term care is the unnecessary transfer of residents to hospital emergency departments, according to Gurau. “In many situations, it’s worth trying as hard as we can to treat them in the nursing home, as opposed to having them go to hospital.”

Researchers estimated that 25% of the transfers from long-term care facilities in Canada to hospital emergency departments in 2014 were potentially preventable.

Urinary tract infections accounted for 30% of hospital emergency department visits for potentially preventable conditions by older patients who are residents in long-term care, according to 2013-2014 data from the Canadian Institute for Health Information.

“There are lots of downsides to going to the hospital [from long-term care],” Gurau told this news organization. “There are risks for infections, risks for increasing delirium and agitation [in patients with dementia], and risks for other behavior that can really impact somebody’s life.”

Gurau reported having no relevant financial relationships.

TOPLINE:

Women with polycystic ovary syndrome (PCOS) have 26% higher nulliparity rates and give birth at more advanced ages despite similar family aspirations and higher rates of fertility treatment. Later PCOS diagnosis is associated with double the rate of advanced maternal age at childbirth.

METHODOLOGY:

• A prospective cohort study followed 14,247 Australian women from 1996 (age, 18-23 years) to 2021 (age, 43-48 years), comparing 981 women with self-reported PCOS against 13,266 without PCOS.
• Participants completed surveys approximately every 3 years, with data collection including childbirth events, fertility issues, and treatment history from 20 weeks of gestational age, including stillbirths.
• Analysis focused on comparing parity, maternal age at deliveries, and factors associated with advanced maternal age between groups, with adjustments made for education level, area of residence, marital status, body mass index group, hypertension, and type 2 diabetes.

TAKEAWAY:

• Compared with women without PCOS, those with PCOS had fewer births (1.9 ± 1.2 vs 1.7 ± 1.3; P < .001) and higher nulliparity rates (18% vs 23%; P = .003).
• PCOS was associated with increased odds of advanced maternal age at first childbirth (adjusted odds ratio [aOR], 1.34; 95% CI, 1.04-1.75) and higher rates of gestational diabetes (aOR, 3.90; 95% CI, 2.99-5.10).
• Late PCOS diagnosis was linked to increased odds of advanced maternal age at first childbirth (aOR, 1.98; 95% CI, 1.22-3.22), emphasizing the importance of early diagnosis.
• Compared with women without PCOS, those with PCOS were older at first childbirth (28.8 ± 5.5 vs 29.5 ± 5.5 years) and second childbirth (31.1 ± 5.0 vs 32.1 ± 5.2 years) (P < .001 for both).

IN PRACTICE:

“Women with PCOS have increased infertility and have higher rates of seeking and using ovulation induction and IVF than those without PCOS. Moreover, women with PCOS are older at both first and second childbirth, have longer interconception periods, are of advanced maternal age, and have higher nulliparity and lower fecundity compared with women without PCOS,” the authors of the study wrote.

This study was led by Maria Forslund, MD, PhD, Department of Obstetrics and Gynecology, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg in Sweden. It was published online in American Journal of Obstetrics & Gynecology.

LIMITATIONS:

This study relied on self-reported PCOS diagnosis, though these data were previously validated in the cohort. While dropouts from the study were common, a previous modeling study showed no serious bias in estimates of associations between risk factors and health outcomes in the longitudinal models.

DISCLOSURES:

TOPLINE:

Women with polycystic ovary syndrome (PCOS) have 26% higher nulliparity rates and give birth at more advanced ages despite similar family aspirations and higher rates of fertility treatment. Later PCOS diagnosis is associated with double the rate of advanced maternal age at childbirth.

METHODOLOGY:

• A prospective cohort study followed 14,247 Australian women from 1996 (age, 18-23 years) to 2021 (age, 43-48 years), comparing 981 women with self-reported PCOS against 13,266 without PCOS.
• Participants completed surveys approximately every 3 years, with data collection including childbirth events, fertility issues, and treatment history from 20 weeks of gestational age, including stillbirths.
• Analysis focused on comparing parity, maternal age at deliveries, and factors associated with advanced maternal age between groups, with adjustments made for education level, area of residence, marital status, body mass index group, hypertension, and type 2 diabetes.

TAKEAWAY:

• Compared with women without PCOS, those with PCOS had fewer births (1.9 ± 1.2 vs 1.7 ± 1.3; P < .001) and higher nulliparity rates (18% vs 23%; P = .003).
• PCOS was associated with increased odds of advanced maternal age at first childbirth (adjusted odds ratio [aOR], 1.34; 95% CI, 1.04-1.75) and higher rates of gestational diabetes (aOR, 3.90; 95% CI, 2.99-5.10).

TOPLINE:

Supplementation with vitamin D and calcium can reduce systolic and diastolic blood pressure in older individuals with overweight, particularly in those with a body mass index (BMI) > 30 and those diagnosed with hypertension.

METHODOLOGY:

• Large cohort data have provided epidemiologic evidence linking vitamin D deficiency to a higher risk for cardiovascular disorders, including hypertension; however, evidence on the beneficial effects of vitamin D supplementation on blood pressure outcomes remains inconclusive.
• A post hoc analysis of a randomized controlled trial was conducted to investigate the effect of two doses of cholecalciferol (vitamin D3) on blood pressure in individuals aged 65 years or older with a BMI > 25 and serum vitamin D levels of 10-30 ng/mL.
• A total of 221 participants were recruited through outpatient departments, clinics, and advertisements in the greater Beirut area and received calcium supplementation in combination with either a low dose (600 IU/d, as recommended by the Institute of Medicine [IOM]) or a high dose (3750 IU/d) of vitamin D3.
• Blood pressure measurements were taken at baseline, 6 months, and 12 months using a SureSigns VS3 monitor.
• Participants were also stratified by BMI and hypertension status to assess the effects of vitamin D and calcium on blood pressure.

TAKEAWAY:

• Systolic and diastolic blood pressures were significantly reduced with vitamin D supplementation in the overall cohort (mean difference, 3.5 and 2.8 mm Hg, respectively; P = .005 and P = .002, respectively), with the effect more prominent in those in the high-dose vitamin D group.
• Participants with a BMI > 30 experienced reductions in both systolic and diastolic blood pressures in the overall cohort (P < .0001 and P = .01, respectively); although the systolic blood pressure was significantly reduced with both high- and low-dose vitamin D, the diastolic blood pressure decreased in the high-dose group only.
• Patients with hypertension benefited from all doses of vitamin D, regardless of the BMI.
• Systolic blood pressure at 6 and 12 months was significantly predicted by BMI and baseline systolic blood pressure measurements, although not by the dose of vitamin D received.

IN PRACTICE:

“Our study found vitamin D supplementation may decrease blood pressure in specific subgroups such as older people, people with obesity, and possibly those with low vitamin D levels,” said study author Ghada El-Hajj Fuleihan, MD, MPH, of the American University of Beirut Medical Center in Beirut, Lebanon, said in a news release. “High vitamin D doses compared to the IOM’s recommended daily dose did not provide additional health benefits.”

It was published online in Journal of the Endocrine Society.

LIMITATIONS:

This study’s limitations included the exploratory nature of the analyses and the low power of the subgroup analyses. Additionally, the study focused on older individuals who were sedentary and had overweight, many of whom had prediabetes — conditions known to influence blood pressure. The possible effect of calcium alone on blood pressure reduction was also unclear.

DISCLOSURES:

This study was supported by grants from the American University of Beirut, St Joseph University, and the Lebanese Council for National Scientific Research. No relevant conflicts of interest were disclosed by the authors.

Overtreatment of men with prostate cancer and limited life expectancy (LE) has persisted in the era of active surveillance and worsened in some instances, according to a new study.

“Overtreatment of men with limited longevity for intermediate- and high-risk tumors has not only failed to improve but has actually worsened over the last 20 years,” Timothy Daskivich, MD, MSHPM, with Cedars-Sinai Medical Center, Los Angeles, said in an interview.

“Many doctors assume that the increase in uptake of active surveillance for low-risk prostate cancers has solved the problem of overtreatment, but this trend has not affected overtreatment of men with low likelihood of living long enough to benefit from treatment who have higher-risk tumors,” Daskivich said.

The study was published online on November 11 in JAMA Internal Medicine.

‘Concerning’ Real-World Data

For men with low- and intermediate-risk prostate cancer expected to live fewer than 10 years, prostate cancer screening and aggressive treatment are not recommended.

Daskivich and colleagues analyzed data on 243,928 men (mean age, 66 years) in the Veterans Affairs (VA) Health System with clinically localized prostate cancer diagnosed between 2000 and 2019.

About 21% had LE < 10 years, and about 4% had LE < 5 years, according to the validated age-adjusted Prostate Cancer Comorbidity Index.

Overtreatment was defined as aggressive treatment (surgery or radiation) in those with LE < 10 years and low- to intermediate-risk disease and in those with LE < 5 years and high-risk disease, in line with current guidelines.

Among men with LE < 10 years, the proportion of men overtreated with surgery or radiotherapy for low-risk disease decreased 22% but increased 22% for intermediate-risk disease during the study period.

Among men with LE < 5 years, the proportion of men treated with definitive treatment for high-risk disease increased 29%.

“While lower-risk tumors are treated less aggressively across the board, including in men with limited longevity, it seems that we are more indiscriminately treating men with higher-risk disease without considering their expected longevity,” Daskivich said in an interview.

 

Is This Happening in the General US Population?

Daskivich noted that the sample included a large sample of men diagnosed with localized prostate cancer in the VA Health System.

“Rates of overtreatment are likely to be lower in the VA [Health System], so the problem may be worse in the community setting. The VA [Health System] has been exemplary in its uptake of active surveillance for low-risk cancers, leading the effort to reduce overtreatment of men with low-risk cancers. However, the problem of overtreatment of men with limited longevity persists in the VA [Health System], underscoring the pervasiveness of this problem,” he explained.

“We don’t have a perfect head-to-head comparison of overtreatment in the VA setting vs in the community. [However, one study shows] that this is not a VA-specific phenomenon and that there is an increase in overtreatment of men with limited longevity in a Medicare population as well,” Daskivich noted.

 

Is Overtreatment All Bad?

Overtreatment of prostate cancer, especially in cases where the cancer is unlikely to progress or cause symptoms, can lead to significant physical, psychological, and financial harms, Christopher Anderson, MD, urologist with Columbia University Irving Medical Center in New York City, who wasn’t involved in the study, noted in an interview.

In the study by Daskivich and colleagues, over three quarters of the overtreatment was radiation therapy, which carries the risk for urinary, bowel, and sexual issues.

“Overscreening, which can lead to overtreatment, is a core issue,” Anderson said. It’s easy to order a “simple” prostate-specific antigen blood test, but in an older man with limited LE, that can lead to a host of further testing, he said.

Stopping the pipeline of overscreening that then feeds into the cascade of overtreatment is the first step in addressing the problem of prostate cancer overtreatment, Nancy Li Schoenborn, MD, MHS, with Johns Hopkins University School of Medicine, Baltimore, and Louise C. Walter, MD, with University of California San Francisco, wrote in an editorial in JAMA Internal Medicine.

Considering LE during screening decision-making is “fundamental to reducing harms of prostate cancer overdiagnosis and overtreatment” because limited LE increases the likelihood of experiencing “harms all along the diagnostic and treatment cascade following screening,” the editorial writers said.

The time spent diagnosing, monitoring, and treating asymptomatic prostate cancer in men with limited LE distracts from monitoring and treating chronic symptomatic life-limiting illnesses, they noted.

 

Tough to Talk About?

Anderson noted that, in general, doctors are not great at estimating and counseling patients on LE. “It’s sometimes difficult to have that conversation,” he said.

Daskivich said physicians may fail to include average LE when advising patients on treatments because they believe that the patients do not want to discuss this topic. “Yet, in interviews with patients, we found that prostate cancer patients reported they wanted this information,” he continued, in an interview.

Solving the problem of overscreening and overtreatment will require a “multifaceted approach, including improving access to life expectancy data at the point of care for providers, educating providers on how to communicate this information, and improving data sources to predict longevity,” Daskivich said.

He said it’s equally important to note that some men with prostate cancer may choose treatment even if they have a limited longevity.

“Not all patients will choose conservative management, even if it is recommended by guidelines. However, they need to be given the opportunity to make a good decision for themselves with the best possible data,” Daskivich said.

This work was supported in part by a US Department of VA Merit Review. Daskivich reported receiving personal fees from the Medical Education Speakers Network, EDAP, and RAND; research support from Lantheus and Janssen; and a patent pending for a system for healthcare visit quality assessment outside the submitted work. Schoenborn, Walter, and Anderson had no relevant disclosures.

Overtreatment of prostate cancer, especially in cases where the cancer is unlikely to progress or cause symptoms, can lead to significant physical, psychological, and financial harms, Christopher Anderson, MD, urologist with Columbia University Irving Medical Center in New York City, who wasn’t involved in the study, noted in an interview.

In the study by Daskivich and colleagues, over three quarters of the overtreatment was radiation therapy, which carries the risk for urinary, bowel, and sexual issues.

“Overscreening, which can lead to overtreatment, is a core issue,” Anderson said. It’s easy to order a “simple” prostate-specific antigen blood test, but in an older man with limited LE, that can lead to a host of further testing, he said.

Stopping the pipeline of overscreening that then feeds into the cascade of overtreatment is the first step in addressing the problem of prostate cancer overtreatment, Nancy Li Schoenborn, MD, MHS, with Johns Hopkins University School of Medicine, Baltimore, and Louise C. Walter, MD, with University of California San Francisco, wrote in an editorial in JAMA Internal Medicine.

Considering LE during screening decision-making is “fundamental to reducing harms of prostate cancer overdiagnosis and overtreatment” because limited LE increases the likelihood of experiencing “harms all along the diagnostic and treatment cascade following screening,” the editorial writers said.

The time spent diagnosing, monitoring, and treating asymptomatic prostate cancer in men with limited LE distracts from monitoring and treating chronic symptomatic life-limiting illnesses, they noted.

 

Tough to Talk About?

Anderson noted that, in general, doctors are not great at estimating and counseling patients on LE. “It’s sometimes difficult to have that conversation,” he said.

Daskivich said physicians may fail to include average LE when advising patients on treatments because they believe that the patients do not want to discuss this topic. “Yet, in interviews with patients, we found that prostate cancer patients reported they wanted this information,” he continued, in an interview.

Solving the problem of overscreening and overtreatment will require a “multifaceted approach, including improving access to life expectancy data at the point of care for providers, educating providers on how to communicate this information, and improving data sources to predict longevity,” Daskivich said.

He said it’s equally important to note that some men with prostate cancer may choose treatment even if they have a limited longevity.

“Not all patients will choose conservative management, even if it is recommended by guidelines. However, they need to be given the opportunity to make a good decision for themselves with the best possible data,” Daskivich said.

This work was supported in part by a US Department of VA Merit Review. Daskivich reported receiving personal fees from the Medical Education Speakers Network, EDAP, and RAND; research support from Lantheus and Janssen; and a patent pending for a system for healthcare visit quality assessment outside the submitted work. Schoenborn, Walter, and Anderson had no relevant disclosures.

WASHINGTON — The B cell–depleting agent inebilizumab (Uplizna) dramatically reduced the risk of flares and increased year-long remission of IgG4-related disease (RD), new research has found.

In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial of 135 adults with active IgG4-RD, treatment with inebilizumab resulted in a significant 87% reduction in flare risk and nearly fivefold greater likelihood of flare-free remission at 1 year. The results were published online November 14 in The New England Journal of Medicine and were presented at the annual meeting of the American College of Rheumatology (ACR).

The drug’s manufacturer, Amgen, released top-line results of the trial, called MITIGATE, in June 2024.

 

Until now, the mainstay of management for the chronic multiorgan disease IgG4-RD has been glucocorticoids, which can cause numerous adverse effects. “It is hoped that inebilizumab can be used as an important steroid-sparing medication in this disease to reduce steroid toxicity,” lead author John H. Stone, MD, professor of medicine at Harvard Medical School, Boston, Massachusetts, said in an interview, noting that it may not entirely eliminate the need for steroid treatment, but for many, it appears to work after the remission induction period as a monotherapy without steroids. 

Asked to comment, Leonard H. Calabrese, DO, head of the Section of Clinical Immunology and manager of the Clinical Immunology Clinic at the Cleveland Clinic, Ohio, said: “There has been anecdotal or observational evidence for some effect with other immunosuppressive agents, including rituximab, but no robust clinical trial until this study. This clearly has demonstrated efficacy by reducing the risk of flares. And most importantly, putting people into remission means no active disease in any given organ. ... This gives us another tool in the toolbox to attack B cell–directed diseases, and I think it really makes a lot of sense.”

Calabrese cautioned, though, that “this is a disease that extends over many years. This is just a 1-year study. Label extensions will be important.”

 

And several questions remain, Calabrese noted: “How long do patients need to remain on drug? What will happen when the drug is stopped? Can they be retreated? These are the natural questions that arise in any sentinel study like this. But this is extremely encouraging. And I think it’s great for patients. I also think it’s a clarion call to increase awareness about this disease since there’s now strong evidence of effective treatment.” 

 

Underrecognized, Often Misdiagnosed as Cancer

Indeed, IgG4-RD, a chronic, relapsing, autoimmune, fibro-inflammatory multiorgan disease, was only first described in Japan in 2003. Since then, it has been reported all over the world yet remains vastly underrecognized. It is often misdiagnosed as cancer because it produces lesions in multiple organs. It received an ICD-10 code only about a year ago. A previous study estimated a prevalence of about 5.3 persons per 100,000 but that is likely to be a three- to fourfold underestimate, said Stone, who is also executive chairman of the IgG4ward! Foundation. 

“Nobody had heard of the disease until about 20 years ago. ... And there are many people in the world who have still not heard of it despite the fact that it is a multiorgan autoimmune disease and is probably as common, or more common, than many other diseases that rheumatologists spend a lot of time thinking about, such as scleroderma.”

While knowledge about the disease is increasing in rheumatology circles, it’s less well-recognized among many of the specialties where patients present, depending on the location of their lesions. These include gastroenterology, ophthalmology, pulmonary medicine, neurology, and nephrology. “All would be likely to see this disease,” Stone said. 

The disease can be mistaken for tumors in many of those locations and even as metastatic cancer, he noted, adding that “any time a patient has a mass lesion in a typical organ, the pancreas, the major salivary glands, the lungs, or the kidneys, this should be on the differential diagnosis.” 

The diagnosis of IgG4-RD is a clinical one, involving “quadrangulation between clinical features, serological findings, IgG4 levels in the blood, radiology studies, and then pathology biopsies when those are available,” Stone said. 

Calabrese characterized the current situation as “we’re all blind men on the elephant. To the neurologist or the neurosurgeon, it’s a mass in the brain. It could present to the ophthalmologist as an [eye] tumor. It can be thyroid gland failure, pulmonary disease, retroperitoneal fibrosis, hepatobiliary disease, and beyond. So, whoever sees that patient, there’s often a long lag time in recognizing it.”

And interestingly, Stone noted that unlike other autoimmune diseases, IgG4-RD primarily affects middle-aged men rather than younger-to-middle-aged women. And when IgG4-RD is diagnosed, glucocorticoid treatment can be particularly toxic when the pancreas is involved, heightening the risk for hyperglycemia and potentially causing diabetes. 

 

Dramatic Improvement in Flares, Remission Achievement

MITIGATE is a phase 3, multicenter, double-blind, randomized, placebo-controlled trial in which 135 adults (mean age 58.2 years, 88 men) with active IgG4-RD were randomized 1:1 to receive 300-mg intravenous infusions of inebilizumab or placebo on days 1 and 15, and again at week 26. At baseline, 62 (45.9%) participants had newly diagnosed IgG4-RD and 73 (54.1%) had recurrent disease. 

Both groups received identical glucocorticoid tapers. Overall, 127 (94.1%) completed the 52 weeks of treatment. 

By 52 weeks, only seven patients in the inebilizumab group (10%) had experienced disease flares vs 40 (60%) in the placebo group, a significant difference with a hazard ratio of 0.13 (P < .001). 

The percentage of participants achieving flare-free, treatment-free complete remission was 59 with inebilizumab (57%), compared with just 15 (22%) in the placebo group (odds ratio [OR], 4.68; P < .001). And for flare-free, glucocorticoid-free complete remission, those proportions were 40 (59%) vs 15 (22%), respectively (OR, 4.96; P < .001). 

Excluding the 8-week glucocorticoid taper period, mean total glucocorticoid use was 1264.2 mg less in the inebilizumab than the placebo group, a significant reduction. Overall, 61 participants (90%) were able to entirely discontinue glucocorticoids during the trial, compared with just 25 (37%) in the placebo group. 

Adverse events of grade 3 or higher occurred in 12 participants (18%) in the inebilizumab group and 8 (12%) in the placebo group; serious adverse events occurred in 12 (18%) and 6 (9%), respectively. However, no serious adverse event occurred in more than one participant, and there were no deaths. Adverse events led to withdrawal from the trial in six patients (9%) in the inebilizumab group and three patients (4%) in the placebo group. 

Adverse events that occurred in more than 10% of participants in the inebilizumab group were COVID-19 in 16 participants (24%), lymphopenia in 11 (16%), and urinary tract infection in 8 (12%). 

Importantly, Stone noted, B-cell depletion can reduce responses to vaccines, so patients should receive all recommended vaccinations, including COVID-19, influenza, respiratory syncytial virus, and others, prior to initiating therapy. 

Uplizna (inebilizumab-cdon) was approved by the Food and Drug Administration (FDA) for the treatment of neuromyelitis optica spectrum disorder in 2020. In October 2024, the FDA granted Amgen breakthrough therapy designation for use in IgG4-RD. The company is also developing the drug for use in myasthenia gravis.

The study was funded by Amgen. Stone has reported being a consultant for Amgen, Zenas, Argenx, Bristol Myers Squibb, Novartis, Sanofi, and Horizon Pharma. Calabrese has reported being a consultant and/or speaker for Amgen, AstraZeneca, Jansen, Sanofi, and UCB.
