Does Omalizumab Cause Atopic Dermatitis Flare-Ups?
To the Editor:
We read with interest the case reported by Yanovsky et al1 (Cutis. 2023;112:E23-E25). We thank the authors for updating our knowledge about atopic dermatitis (AD) and omalizumab and improving our understanding of the various wanted and unwanted effects that may manifest with omalizumab. We wish to clarify a few points on omalizumab use.
First, Yanovsky et al1 reported that their patient’s AD flares occurred within a few days after omalizumab injections to control asthma, possibly because omalizumab may have caused a paradoxical increase in sensitivity to other cytokines such as IL-33 in basophils and increased IL-4/IL-13 production in the skin. The authors cited Imai2 to explain that IL-33 plays a role in the pathogenesis of AD, increases itching, and disrupts the skin barrier. However, Imai2 did not discuss a relationship with omalizumab. As a recombinant humanized IgG1 monoclonal anti-IgE antibody, omalizumab works by interacting with the high-affinity receptor Fc epsilon RI that typically is found on eosinophils, mast cells, and basophils and plays a critical role in preventing the allergic cascade.3 We could not find any studies in the literature regarding omalizumab having a specific effect on the skin, causing cytokine imbalance, or increasing IL-4/IL-13 levels.
Second, the case report indicated that AD lesions improved with the biologic dupilumab,1 which seems amazing. Dupilumab is a monoclonal antibody used in patients with moderate to severe AD that blocks IL-4/IL-13 signaling and thus inhibits receptor signaling downstream of the Janus kinase signal transducer and activator of transcription protein pathway.4 It also has been shown to be beneficial in children with moderate to severe uncontrolled asthma.5 In vivo studies are needed to learn about the effects of these biologics on asthma and AD, whose complex immunologic effects are increasingly well understood by real patient experience.
Third, omalizumab has been found to relieve AD, not exacerbate it, in our own experience with 7 patients (unpublished data, 2024) and randomized controlled trials.6
Fourth, Yanovsky et al1 reported that the patient’s lesions flared up within a few days after taking omalizumab, which suggests a non-IgE delayed reaction. Could this reaction be related to polysorbate 20 used as an excipient in the commercial preparation? When we examined both preparations, the presence of polysorbate 80 in dupilumab was noteworthy,7 unlike omalizumab. We suggest the authors perform a patch test including polysorbate 20 and polysorbate 80.
Finally, the authors mentioned that omalizumab may cause a paradoxical exacerbation of AD in certain patients, as in tumor necrosis factor α inhibitor–induced psoriasis.8 This has been reported,8 but tumor necrosis factor α inhibitors are cytokine inhibitors and can lead to cytokine imbalance, while omalizumab is an IgE inhibitor.
Yanovsky et al1 described AD flares as “triggered by omalizumab,” which we believe was not the case. Because this patient had chronic AD, other causes of AD exacerbation in this patient could include stress or infection. Also, when they say that AD is triggered or induced, it implies that they are attributing the occurrence/development of AD in this patient to omalizumab. Of course, this also is not true.

Thank you for your thoughtful comments. Although we agree that we cannot prove omalizumab was the cause of our patient’s AD flares, the new onset of severely worsening disease that was exacerbated by each dose of omalizumab as well as subsequent resolution upon switching to dupilumab was highly suggestive for a causal relationship. Our goal was to alert physicians to the possibility of this phenomenon and to encourage further study.

Mental Health Services: The Missing Piece or Missing Peace for Patients With Atopic Dermatitis
There is a well-established connection between the mind and the skin, and it is clear that this relationship is bidirectional—not only does skin disease increase the risk for depression, anxiety, sleep disturbance, and suicidality, but psychologic stress actually can worsen skin disease through multiple mechanisms, including direct damage to the skin barrier.1,2 Psychologic stress also impacts the microbiome, another critical driver of skin disease.3,4 The concept of the itch-scratch cycle vividly illustrates the vicious interplay between the mind and body in atopic dermatitis (AD).
However, patients with AD are not the only ones impacted—caregivers also experience psychologic stress. Remarkably, one study of patients with AD and their caregivers found that the caregivers actually reported significantly worse mental health and anxiety (P=.01 and P=.03, respectively) than patients themselves, even when controlling for the severity of disease.5
Thus, it would seem obvious for mental health to be a central component of AD care—to improve patient and caregiver quality of life while also improving symptoms. Research has actually borne this out, with one systematic review and meta-analysis concluding that psychological intervention has a beneficial effect on AD,6 and another that the addition of psychological and educational interventions to conventional treatment provided better therapeutic results in alleviating eczema severity and psychological symptoms.7 One study demonstrated that patients with AD who received cognitive behavioral therapy via the internet displayed a statistically significant improvement in their disease (P<.001) as measured by the Patient-Oriented Eczema Measure compared with those in the control group who received standard care alone. They also reported improvements in perceived stress, sleep problems, and depression in the intervention group that were sustained at 1-year follow-up.8 These findings are particularly impactful because clinical results were achieved while leveraging an internet-based approach to therapy.
Regrettably, despite the preponderance of evidence supporting the connection between mental health and AD, there remain considerable unmet needs. A recent cross-sectional survey of 954 adults with AD and caregivers of children with AD (N=954) conducted by the National Eczema Association found that half of patients were never asked about mental health during any of their visits, and of those referred for mental health resources, only 57% utilized the recommended services.9 Importantly, patients aged 18 to 34 years reported wanting to be asked about mental health. Of those who did receive referrals, most were for counseling services (23%), followed by alternative mental health therapy such as music or art therapy (15%), cognitive behavioral therapy (13%), or peer/social support groups (12%). Approximately 10% reported receiving a pamphlet or a brochure only.9
Physicians who treat patients with AD can and must do better, but first we must explore why these referral rates are so low. As with many complex problems, there is unlikely to be one simple unifying reason. As expected, the answer is nuanced and multifaceted, and—most importantly—staggeringly incomplete.
For starters, mental health interventions rarely are as easy as applying a cream or taking a pill. Hedman-Lagerlöf et al8 specifically pointed out that although their approach—using internet-based cognitive behavioral therapy—was explicitly designed to be more accessible with fewer resources, it required approximately 35 hours of treatment over 12 weeks, requiring both substantial time and commitment from patients who often are already burned out and exhausted due to AD. They even underscored that the most commonly reported adverse effect of therapy was increased stress or worry, making it a difficult sell.8
Even before most patients have a chance to consider the time required and the potential adverse effects of mental health interventions for AD, greater hurdles exist. Finances, medical insurance, and wait times were highlighted as barriers to care in a systematic review.10 These are deep-seated problems in the United States; while they may be surmountable in certain geographic areas, the frequency with which these concerns arise means that it does not take too many failed attempts at referring patients for mental health services before clinicians just give up—similar to any form of operant conditioning.
A more elusive concept is stigmatization. Although it may not be quantifiable, the idea is that patients may encounter additional challenges when seeking mental health care, either because the interactions themselves may worsen their symptoms (eg, increased anxiety) or they may be more likely to have a negative perception of the experience.11 A 2020 systematic review of barriers to addressing common mental health problems found that stigma was the most prominent barrier in adolescents, with the second most prominent being negative attitudes and beliefs about mental health services and professionals.12 As a clinician, I can attest that I have sometimes detected skepticism when I have suggested mental health services to patients and have even been asked outright if I thought the problem was all in their head. My patients with AD generally have been much more open to the idea of mental health support, especially after I explain the powerful mind-body connection, than patients with other conditions—most notably delusions of parasitosis—who have been much more dismissive of such overtures. An oft-cited paper from 1976 frames the problem perfectly, describing what can happen after a referral for mental health services.13 The authors stated that the suggestion of mental health makes patients feel that the dermatologist does not believe them in the first place. Beyond this, the authors pointed out that referring the patient elsewhere reduces their hopes for dermatologic treatment.13
Knowing now—perhaps more than ever before—that the mind and skin are intimately connected compels us to solve these problems and find ways around these obstacles. Selecting the optimal forms of mental health services for each patient, having the structural support of the health care system, and winning the trust of patients and caregivers while combating stigma are undoubtedly tall orders; however, understanding the stakes for patients with AD, their caregivers, and society as a whole should inspire us to keep pushing forward.

Although it may not be quantifiable, the idea is that patients may encounter additional challenges when seeking mental health care, either because the interactions themselves may worsen their symptoms (eg, increased anxiety) or they may be more likely to have a negative perception of the experience.11 A 2020 systematic review of barriers to addressing common mental health problems found that stigma was the most prominent barrier in adolescents, with the second most prominent being negative attitudes and beliefs about mental health services and professionals.12 As a clinician, I can attest that I have sometimes detected skepticism when I have suggested mental health services to patients and have even been asked outright if I thought the problem was all in their head. My patients with AD generally have been much more open to the idea of mental health support, especially after I explain the powerful mind-body connection, than patients with other conditions—most notably delusions of parasitosis—who have been much more dismissive of such overtures. An oft-cited paper from 1976 frames the problem perfectly, describing what can happen after a referral for mental health services.13 The authors stated that the suggestion of mental health makes patients feel that the dermatologist does not believe them in the first place. Beyond this, the authors pointed out that referring the patient elsewhere reduces their hopes for dermatologic treatment.13
Knowing now—perhaps more than ever before—that the mind and skin are intimately connected compels us to solve these problems and find ways around these obstacles. Selecting the optimal forms of mental health services for each patient, having the structural support of the health care system, and winning the trust of patients and caregivers while combating stigma are undoubtedly tall orders; however, understanding the stakes for patients with AD, their caregivers, and society as a whole should inspire us to keep pushing forward.

Practice Points
- The mind-body connection plays a role in many conditions, including atopic dermatitis.
- Atopic dermatitis can make patients feel anxious, stressed, and depressed; at the same time, those feelings can lead to worsening of the condition.
- There are many barriers to getting mental health care in the United States, from financial constraints to stigmatization.
- Mental health is part of overall health and should be more highly prioritized by all physicians.
Depiction of Cancer in Movies: Not an Accurate Portrayal
This transcript has been edited for clarity.
I’d like to talk about a very different topic from what I normally discuss, which is probably relatively rarely addressed in clinical conversations among clinicians. There was a very provocative commentary that appeared in JCO Oncology Practice, titled “Hollywood’s Take on Oncology: Portrayal of Cancer in Movies, 2010-2020.”
All of us, as we grow up — as kids, adolescents, young adults, adults, and older individuals — watch television and movies. The older of us know that the doctor in everybody’s home that we all wanted was Marcus Welby. Of course, there was Dr. Kildare, ER, Grey’s Anatomy, and St. Elsewhere. There was Love Story and Brian’s Song. We all know about these.
This particular review was fascinating. The authors looked at 100 English-language movies that had cancer included in the storyline over the past decade. They asked some relatively simple questions: How did they discuss it? What were the tumor types they discussed? What were the outcomes?
The question is, what is the public seeing? If you watch these movies and you don’t have family experience or personal experience with cancer, what do you think about cancer? Maybe this is what you know about it. Despite what the National Cancer Institute or the American Society of Clinical Oncology tells you, this may be what you know.
What they showed was really quite interesting.
There is another very interesting phenomenon. What do you think was the most common cancer type when they did define the cancer? It was brain tumors, even though we know that brain tumors are certainly not even within the top 10. They’re obviously very serious cancers, but if you’re talking about common cancers, brain cancer doesn’t rank in the top 10, and it was the most common cancer on these shows.
The authors of this paper made the point of whether this would be an opportunity for filmmakers. Again, with the storyline, they’re trying to sell a product here, but wouldn’t this be the opportunity to provide some information about the reality of cancer? They could emphasize the fact that smokers get lung cancer. In my opinion, they could discuss cervical cancer and comment that if HPV vaccination had been done, maybe this would not have happened.
They noted that the majority of cancers in these movies were incurable, and they commented that that’s not the reality today. Today, obviously, many of our cancers that weren’t curable have become quite curable for a percentage of patients, in addition to which, obviously, with early detection, we have a very high cure rate. How about trying to get that message out, too, that we’ve actually had increasing success?
They commented that there was very rarely, if ever, a conversation about multidisciplinary care, that somehow there are multiple doctors with multiple specialties involved. They noted that this is potentially a very important message to give out. They commented that in 12 of these movies, the patient refused cancer care. Again, that happens, but it’s clearly a rare event today. Maybe this is not really a very accurate depiction of what’s going on.
They commented on the fact that, obviously, we’re going back through the past 10 years, so there were no patients who received immunotherapy or targeted therapy. Again, the goal here is not to sell oncology care but to be accurate, or more accurate, about the state of treatment to the extent you can.
They noted that, in fact, there was essentially very little, if any, comment on palliative care or hospice care. The final point they made is that there was very little conversation in these movies about what we now recognize as financial distress in many of our patients. That’s an unfortunate reality and perhaps that might come in the future.
Again, the point of this was not to tell Hollywood how to make their movies but to have the oncology community recognize that if their patients or the families of their patients are seeing these movies, they are not getting a very accurate picture of what is happening in the oncology world today and that some education may very well be required.
Maurie Markman is Professor, Department of Medical Oncology and Therapeutics Research, City of Hope, Duarte, California, and President of Medicine & Science, City of Hope Atlanta, Chicago, and Phoenix.

Vacationing Doctors Intervene After Shark Attack
Ryan Forbess, MD: I live at the beach in Orange Beach, Alabama. I’ve lived in Hawaii, the Caymans, and other beach areas for years. I’ve seen a lot of sharks but never a shark attack. Not until now.
Mohammad Ali, MD: Ryan and I have been friends for 20 years. Every year, my family goes to 30A in Florida (a popular resort stretch of highway) to celebrate my wife’s birthday, and the Forbesses always meet us there. This year we had a group of about 18 people.
On Friday, it was beautiful, and we decided to make it a beach day. We had nine kids with us. So by the time we rounded them up and got there, it was noon, and there was nowhere to sit. We almost turned around and went to the pool. But my wife finally found a spot for an umbrella.
Dr. Forbess: We were in the water boogie boarding. I was with my 8-year-old son, and Mo was with his daughter who is the same age. Suddenly, we noticed a lot of commotion just to the left of us. My first thought was: Someone saw a shark, not an attack. They’re so rare. But seeing one would scare people.
We grabbed our kids and started running out of the water. As we got closer to the shore,
Dr. Ali: It was mass panic. People were screaming and running out of the water. Other people were running in and grabbing their kids. Everyone just looked frantic.
We saw two men dragging this poor girl out of the water. It was surreal. The majority of her right leg was severed, her femur bone visible and stark white; it didn’t look real. I kept telling myself I was in a dream and now I’d wake up.
A young EMT who was there had put an informal tourniquet on her leg, but she was still bleeding. So I compressed the femoral artery as hard as I could, something I’m very familiar with doing.
Dr. Forbess: People asked me later what we used for a tourniquet. I said, “Mo’s big hands.” I tease him because most doctors play golf or go fishing; Mo lives in the gym. He was just holding pressure.
The girl’s left hand was also severed off at the wrist. There were two nurses there, and they helped with holding tourniquets on her arm.
Lulu (the girl’s name) was 15 years old. She was in and out of consciousness. At one point, her face started getting really pale, so we tried to lift her extremities up to keep the blood flow to the heart. With such severe blood loss, I thought she might go into cardiovascular shock, and we would have to start compressions. But she had a pulse, and she was breathing.
Dr. Ali: The beach was very crowded, and a lot of people had gathered around. Everyone was emotional, shocked, really shaken up. But they gave us space to work.
Dr. Forbess: People were handing us things — towels, a ratchet strap to use as a tourniquet. There was even an anesthesiologist there who said, “If you need an airway, let me know.” It was like we had a trauma team.
Dr. Ali: Lulu’s mom had been having lunch with friends. When she saw all the commotion, she ran down to the beach to look for her daughter. It was heartbreaking to hear her screams when she saw Lulu. But I was able to tune it out because we had to just concentrate on decreasing the loss of blood.
Dr. Forbess: Another girl came over and said, “That’s my sister.” Lulu has a twin. So she sat there holding Lulu’s hand and being with her the whole time.
Waiting for the EMTs to get there, the seconds were like hours. It seemed like it took forever. Finally, they came, and we were able to get the real tourniquets on, get her boarded and off the beach.
After that, they closed the beach. We got all our stuff and got on the little trolley that would take us back to the house. The lady who was driving asked us, “Did y’all hear about the shark attack?” My wife said, “Yeah, we were there.” And she said, “No, there was one an hour and a half ago.”
Dr. Ali: What we didn’t know was there had been two other attacks that day. Around the same time, one of Lulu’s friends was bitten and got a flesh wound on her heel. And before that, about 4 miles away, there was a serious injury: A lady in her 40s lost her hand and forearm and was bitten in the pelvis.
Dr. Forbess: At that point, my wife leaned back to me and said, “You know we’re never going to the beach again, right? We’re never ever going to the beach.”
If we had known about those attacks, we definitely wouldn’t have been in the water.
Dr. Ali: My wife has never liked going in the water. The evening before, we had debated about taking our daughters in the ocean because she was worried about sharks. I had given her this condescending speech about waist-deep water and the statistical probabilities of ever witnessing a shark attack. I was in trouble.
Dr. Forbess: We didn’t know if Lulu would make it. I’ve done rural family medicine in Oklahoma, so I’ve seen my fair share of injuries — guys on oil rigs, this and that. But I had never seen anything like this kind of trauma and blood loss.
Later that day, I called my office manager to catch up with her and told her what happened. She was actually in Pensacola having dinner across the street from Sacred Heart Hospital where they had taken Lulu. She went over to the emergency room to try to find out Lulu’s status — she was alive.
My office manager was able to go upstairs and talk to Lulu’s mom. Then she called, and we talked to her mom on the phone. She just said, “Thank you for helping my daughter.” It was an emotional moment.
Dr. Ali: It was such a relief. We had no idea how things would turn out. Even if Lulu did survive, was she going to be neurologically sound? But thank God she was. We were so relieved to hear her mom say that it was looking good. We still didn’t know for sure. But at least she was alive and seemed to be functioning.
Dr. Forbess: A few days later, my wife and I went to go visit her at the hospital. Her mom and her grandma were there. They were giving us hugs. We FaceTimed Mo because he was back in Jackson. It was really amazing.
What are the odds? The chances of a shark attack are about one in 12 million. And to have two physicians trained in trauma, a trauma nurse, another nurse, and an anesthesiologist less than 20 yards away when it happened? It’s crazy to think about.
Dr. Ali: And we almost weren’t there. We could have turned away.
Dr. Forbess: Humans are on top of the food chain. Or we think we are. But water really isn’t our element. Against a 12-foot bull shark, we don’t stand a chance. Lulu is here though. It’s unbelievable.
Her mom told me that when Lulu woke up, she just said, “I made it!” That girl is meant to be here. She is a tough girl with a great personality. She has these new prosthetics now that she can move with her mind; it’s like Star Wars. She says she wants to be a physician someday. So she’ll probably cure cancer.
Dr. Forbess is a family medicine physician at Orange Beach Family Medicine in Orange Beach, Alabama. Dr. Ali is an interventional radiologist with Baptist Memorial Health in Jackson, Mississippi.

Later that day, I called my office manager to catch up with her and told her what happened. She was actually in Pensacola having dinner across the street from Sacred Heart Hospital where they had taken Lulu. She went over to the emergency room to try to find out Lulu’s status — she was alive.
My office manager was able to go upstairs and talk to Lulu’s mom. Then she called, and we talked to her mom on the phone. She just said, “Thank you for helping my daughter.” It was an emotional moment.
Dr. Ali: It was such a relief. We had no idea how things would turn out. Even if Lulu did survive, was she going to be neurologically sound? But thank God she was. We were so relieved to hear her mom say that it was looking good. We still didn’t know for sure. But at least she was alive and seemed to be functioning.
Dr. Forbess: A few days later, my wife and I went to go visit her at the hospital. Her mom and her grandma were there. They were giving us hugs. We FaceTimed Mo because he was back in Jackson. It was really amazing.
What are the odds? The chances of a shark attack are about one in 12 million. And to have two physicians trained in trauma, a trauma nurse, another nurse, and an anesthesiologist less than 20 yards away when it happened? It’s crazy to think about.
Dr. Ali: And we almost weren’t there. We could have turned away.
Dr. Forbess: Humans are on top of the food chain. Or we think we are. But water really isn’t our element. Against a 12-foot bull shark, we don’t stand a chance. Lulu is here though. It’s unbelievable.
Her mom told me that when Lulu woke up, she just said, “I made it!” That girl is meant to be here. She is a tough girl with a great personality. She has these new prosthetics now that she can move with her mind; it’s like Star Wars. She says she wants to be a physician someday. So she’ll probably cure cancer.

Ryan Forbess, MD: I live at the beach in Orange Beach, Alabama. I’ve lived in Hawaii, the Caymans, and other beach areas for years. I’ve seen a lot of sharks but never a shark attack. Not until now.
Mohammad Ali, MD: Ryan and I have been friends for 20 years. Every year, my family goes to 30A in Florida (a popular resort stretch of highway) to celebrate my wife’s birthday, and the Forbesses always meet us there. This year we had a group of about 18 people.
On Friday, it was beautiful, and we decided to make it a beach day. We had nine kids with us. So by the time we rounded them up and got there, it was noon, and there was nowhere to sit. We almost turned around and went to the pool. But my wife finally found a spot for an umbrella.
Dr. Forbess: We were in the water boogie boarding. I was with my 8-year-old son, and Mo was with his daughter who is the same age. Suddenly, we noticed a lot of commotion just to the left of us. My first thought was: Someone saw a shark, not an attack. They’re so rare. But seeing one would scare people.
We grabbed our kids and started running out of the water. As we got closer to the shore,
Dr. Ali: It was mass panic. People were screaming and running out of the water. Other people were running in and grabbing their kids. Everyone just looked frantic.
We saw two men dragging this poor girl out of the water. It was surreal. The majority of her right leg was severed, her femur bone visible and stark white; it didn’t look real. I kept telling myself I was in a dream and now I’d wake up.
A young EMT who was there had put an informal tourniquet on her leg, but she was still bleeding. So I compressed the femoral artery as hard as I could, something I’m very familiar with doing.
Dr. Forbess: People asked me later what we used for a tourniquet. I said, “Mo’s big hands.” I tease him because most doctors play golf or go fishing; Mo lives in the gym. He was just holding pressure.
The girl’s left hand was also severed off at the wrist. There were two nurses there, and they helped with holding tourniquets on her arm.
Lulu (the girl’s name) was 15 years old. She was in and out of consciousness. At one point, her face started getting really pale, so we tried to lift her extremities up to keep the blood flow to the heart. With such severe blood loss, I thought she might go into cardiovascular shock, and we would have to start compressions. But she had a pulse, and she was breathing.
Dr. Ali: The beach was very crowded, and a lot of people had gathered around. Everyone was emotional, shocked, really shaken up. But they gave us space to work.
Dr. Forbess: People were handing us things — towels, a ratchet strap to use as a tourniquet. There was even an anesthesiologist there who said, “If you need an airway, let me know.” It was like we had a trauma team.
Dr. Ali: Lulu’s mom had been having lunch with friends. When she saw all the commotion, she ran down to the beach to look for her daughter. It was heartbreaking to hear her screams when she saw Lulu. But I was able to tune it out because we had to just concentrate on decreasing the loss of blood.
Dr. Forbess: Another girl came over and said, “That’s my sister.” Lulu has a twin. So she sat there holding Lulu’s hand and being with her the whole time.
Waiting for the EMTs to get there, the seconds were like hours. It seemed like it took forever. Finally, they came, and we were able to get the real tourniquets on, get her boarded and off the beach.
After that, they closed the beach. We got all our stuff and got on the little trolley that would take us back to the house. The lady who was driving asked us, “Did y’all hear about the shark attack?” My wife said, “Yeah, we were there.” And she said, “No, there was one an hour and a half ago.”
Dr. Ali: What we didn’t know was there had been two other attacks that day. Around the same time, one of Lulu’s friends was bitten and got a flesh wound on her heel. And before that, about 4 miles away, there was a serious injury: A lady in her 40s lost her hand and forearm and was bitten in the pelvis.
Dr. Forbess: At that point, my wife leaned back to me and said, “You know we’re never going to the beach again, right? We’re never ever going to the beach.”
If we had known about those attacks, we definitely wouldn’t have been in the water.
Dr. Ali: My wife has never liked going in the water. The evening before, we had debated about taking our daughters in the ocean because she was worried about sharks. I had given her this condescending speech about waist-deep water and the statistical probabilities of ever witnessing a shark attack. I was in trouble.
Dr. Forbess: We didn’t know if Lulu would make it. I’ve done rural family medicine in Oklahoma, so I’ve seen my fair share of injuries — guys on oil rigs, this and that. But I had never seen anything like this kind of trauma and blood loss.
Later that day, I called my office manager to catch up with her and told her what happened. She was actually in Pensacola having dinner across the street from Sacred Heart Hospital where they had taken Lulu. She went over to the emergency room to try to find out Lulu’s status — she was alive.

Delayed Bleeding: The Silent Risk for Seniors
This discussion was recorded on August 2, 2024. This transcript has been edited for clarity.
Robert D. Glatter, MD: Today, we’ll be discussing the results of a new study published in The Journal of Emergency Medicine, looking at the incidence of delayed intracranial hemorrhage among older patients taking preinjury anticoagulants who present to the emergency department (ED) with blunt head trauma.
Joining me today is the lead author of the study, Dr. Richard Shih, professor of emergency medicine at Florida Atlantic University. Also joining me is Dr. Christina Shenvi, associate professor of emergency medicine at the University of North Carolina (UNC) Chapel Hill, with fellowship training in geriatric emergency medicine.
Welcome to both of you.
Richard D. Shih, MD: Thanks, Rob.
Christina L. Shenvi, MD, PhD, MBA: Thanks. Pleasure to be here.
ICH Study Methodology
Dr. Glatter: It’s a pleasure to have you. Rich, this is a great study and targeted toward a population we see daily in the emergency department. I want you to describe your methodology, patient selection, and how you went about organizing your study to look at this important finding of delayed intracranial hemorrhage, especially in those on anticoagulants.
Dr. Shih: This all started for our research team when we first read the 2012 Annals of Emergency Medicine paper. The first author was Vincenzo Menditto, and he looked at a group of patients that had minor head injury, were anticoagulated, and had negative initial head CTs.
There were about 100 patients, of which about 10 of them did not consent, but they hospitalized all these patients. These were anticoagulated, negative-first head CTs. They hospitalized the patients and then did a routine second CT at about 24 hours. They also followed them for a week, and it turned out a little over 7% of them had delayed head CT.
We were wondering how many delayed intracranial hemorrhages we had missed because current practice for us was that, if patients had a good physical exam, their head CT was normal, and everything looked good, we would send them home.
Because of that, a number of people across the country wanted to verify those findings from the Menditto study. We tried to design a good study to answer that question. We happen to have a very large geriatric population in Florida, and our ED census is very high for age over 65, at nearly 60%.
There are two Level I trauma centers in Palm Beach County. We included a second multicenter hospital, and we prospectively enrolled patients. We know the current state of practice is not to routinely do second CTs, so we followed these patients over time and followed their medical records to try to identify delayed bleeding. That’s how we set up our methodology.
Is It Safe to Discharge Patients With Trauma After 24 Hours?
Dr. Glatter: For the bulk of these patients with negative head CTs, it’s been my practice that when they’re stable and they look fine and there’s no other apparent, distracting painful trauma, injuries and so forth, they’re safe to discharge.
The secondary outcome in your study is interesting: the need for neurosurgical intervention in terms of those with delayed intracranial hemorrhage.
Dr. Shih: I do believe that it’s certainly not the problem that Menditto described, which is 7%. There are two other prospective studies that have looked at this issue with delayed bleeding on anticoagulants. Both of these also showed a relatively low rate of delayed bleeding, which is between like 0.2% and 1.0%. In our study, it was 0.4%.
The difference in the studies is that Menditto and colleagues routinely did 24-hour head CTs. They admitted everybody. For these other studies, routine head CT was not part of it. My bet is that there is a rate of delayed bleeding somewhere in between that seen in the Menditto study and that in all the other studies.
However, talking about significant intracranial hemorrhage, ones that perhaps need neurosurgery, I believe most of them are not significant. There’s some number that do occur, but the vast majority of those probably don’t need neurosurgery. We had 14 delayed bleeds out of 6000 patients with head trauma. One of them ended up requiring neurosurgery, so the answer is not zero, but I don’t think it’s 7% either.
Dr. Glatter: Dr. Shenvi, I want to bring you into the conversation to talk about your experience at UNC, and how you run things in terms of older patients with blunt head trauma on preinjury anticoagulants.
Dr. Shenvi: Thanks, Rob. I remember when this paper came out showing this 7% rate of delayed bleeding and the question was, “Should we be admitting all these people?” Partly just from an overwhelming need for capacity that that would bring, it just wasn’t practical to say, “We’re going to admit every patient with a negative head CT to the hospital and rescan them.” That would be hundreds or thousands of patients each year in any given facility.
The other thing is that delayed bleeds don’t always happen just in the first 24 hours. It’s not even a matter of bringing patients into observation for 24 hours, watching them, and rescanning them if they have symptoms. It can occur several days out. That never, in almost any institution that I know of, became standard practice.
The way that it did change my care was to give good return precautions to patients, to make sure they have somebody with them to say, “Hey, sometimes you can have bleeding several days out after a fall, even though your CT scan here today looks perfect,” and to alert them that if they start having severe headaches, vomiting, or other symptoms of intracranial hemorrhage, that they should come back.
I don’t think it ever became standard practice, and for good reason, because that was one study. The subsequent studies that Richard mentioned, pretty quickly on the heels of that initial one, showed a much lower rate of delayed ICH with the caveats that the methodology was different.
Shift in Anticoagulants
Dr. Shenvi: One other big change from that original study, and now to Richard’s study, is the shift in anticoagulants. Back in the initial study you mentioned, it was all warfarin. We know from other studies looking at warfarin vs the direct oral anticoagulants (DOACs) that DOACs have lower rates of ICH after a head injury, lower rates of need for neurosurgical intervention, and lower rates of discharge to a skilled nursing facility after an intracranial hemorrhage.
Across the board, we know that the DOACs tend to do better. It’s difficult to compare newer studies because it’s a different medication. It did inform my practice to have an awareness of delayed intracranial hemorrhage so that I warn patients more proactively.
Dr. Glatter: I haven’t seen a patient on warfarin in years. I don’t know if either of you have, but it’s all DOACs now unless there’s some other reason. That shift is quite apparent.
Dr. Shih: The problem with looking at delayed bleeding for DOACs vs warfarin is the numbers were so low. I think we had 13 people, and seven were in the no-anticoagulant group. The numbers are even lower, so it’s hard to say.
I just wanted to comment on something that Dr. Shenvi said, and I pretty much agree with everything that she said. Anticoagulants and warfarin, and that Menditto study, have a carryover effect. People group DOACs with warfarin similarly. When a patient is brought in, the first thing they talk about with head trauma is, “Oh, they’re on an anticoagulant” or “They’re not on an anticoagulant.” It’s so ingrained.
I believe that, in emergency medicine, we’re pressed for space and time and we’re not as affected by that 24-hour observation. Maybe many of our surgeons will automatically admit those patients.
I haven’t seen a guideline from the United States, but there are two international guidelines. One is from Austria from 2019, and one is from Scandinavia. Both recommended 24-hour observation if you’re on an anticoagulant.
There is a bit of controversy left over with that. Hopefully, as more and more of information, like in our study, comes out, people will be a little bit more clear about it. I don’t think there’s a need to routinely admit them.
I do want to mention that the Menditto study had such a massive impact on everybody. They pointed out one subgroup (and it’s such a small number of patients). They had seven cases of delayed bleeding; four or five of them were within that 24 hours, and a couple were diagnosed later over the next couple days.
Of those seven people, four of them had international normalized ratios (INRs) greater than 3. Of those four patients, I’ve heard people talk about this and recommend, “Okay, that’s the subgroup I would admit.” There’s a toss-up with what to do with DOAC because it’s very hard to tell whether there’s an issue, whether there are problems with their dosing, and whatever.
We actually recently looked at that. We have a much larger sample than four: close to 300 patients who were on warfarin. We looked at patients who had INRs below 3 and above 3, and we didn’t show a difference. We still don’t believe that warfarin is a big issue with delayed bleeding.
Should We Be Asking: ‘Are They on Blood Thinners?’
Dr. Shenvi: One of the interesting trends related to warfarin and the DOACs vs no anticoagulant is that as you mentioned, Dr Shih, the first question out of people’s mouths or the first piece of information emergency medical services gives you when they come in with a patient who’s had a head injury is, “Are they on blood thinners or not?”
Yet, the paradigm is shifting to say it’s not actually the blood thinners themselves that are giving older patients the higher risk for bleeding; it’s age and other comorbidities.
Certainly, if you’re on an anticoagulant and you start to bleed, your prognosis is much worse because the bleeding doesn’t stop. In terms of who has a bleeding event, there’s much less impact of anticoagulation than we used to think. That, in part, may be due to the change from warfarin to other medications.
Some of the experts I’ve talked to who have done the research on this have said, “Well, actually, warfarin was more of a marker for being much older and more frail, because it was primarily prescribed to older patients who have significant heart disease, atrial fibrillation, and so on.” It was more a marker for somebody who is at risk for an intracranial hemorrhage. There are many changes that have happened in the past 10 years with medications and also our understanding.
Challenges in Patient Follow-up
Dr. Glatter: That’s a great point. One thing, Rich, I want to ask you about is in terms of your proxy outcome assessment. When you use that at 14 and 60 days with telephone follow-up and then chart review at 60 and 90 days (because, obviously, everyone can’t get another head CT or it’s difficult to follow patients up), did you find that worked out well in your prospective cohort study, in terms of using that as a proxy, so to speak?
Dr. Shih: I would say to a certain extent. Unfortunately, we don’t have access to the patients to come back to follow up all of them, and there was obviously a large number of patients in our study.
The next best thing was that we had dedicated research assistants calling all of the patients at 14 days and 60 days. I’ve certainly read research studies where, when they call them, they get 80%-90% follow-up, but we did not achieve that.
I don’t know if people are more inundated with spam phone calls now, or the older people are just afraid of picking up their phone sometimes with all the scams and so forth. I totally understand, but in all honesty, we only had about a 30%-35% follow-up using that follow-up pathway.
Then the proxy pathway was to look at their charts at 60 and 90 days. Also, we looked at the Florida death registry, which is pretty good, and then finally, we had both Level I trauma centers in the county that we were in participating. It’s standard practice that if you have an intracranial hemorrhage at a non–Level I trauma center, you would be transferred to a Level I trauma center. That’s the protocol. I know that’s not followed 100% of the time, but that’s part of the proxy follow-up. You could criticize the study for not having closer to 90% actual contact, but that’s the best we could do.
Dr. Glatter: I think that’s admirable. Using that paradigm of what you described certainly allows the reader to understand the difficulty in assessing patients that don’t get follow-up head CT, and hardly anyone does that, as we know.
To your point of having both Level I trauma centers in the county, that makes it pretty secure. If we’re going to do a study encompassing a similar type of regional aspect, it would be similar.
Dr. Shenvi: I think your proxies, to your credit, were as good as you can get. You can never get a 100% follow-up, but you really looked at all the different avenues by which patients might present, either in the death registry or a Level I center. Well done on that aspect.
Determining When to Admit Patients for Observation
Dr. Glatter: In terms of admissions: You admit a patient, then you hear back that this patient should not have been admitted because they had a negative head CT, but you put them in anyway in the sense of delayed bleeding happening or not happening.
It’s interesting. Maybe the insurers will start looking at this in some capacity, based on your study, that because it’s so infrequent that you see delayed bleeding, that admitting someone for any reason whatsoever would be declined. Do you see that being an issue? In other words, [do you see] this leading to a pattern in terms of the payers?
Dr. Shih: Certainly, you could interpret it that way, and that would be unfortunate. The [incidence of] delayed bleeding is definitely not zero. That’s the first thing.
The second thing is that when you’re dealing with an older population, having some sense that they’re not doing well is an important contributor to trying to fully assess what’s going on — whether or not they have a bleed or whether they’re at risk for falling again and then hitting their head and causing a second bleed, and making sure they can do the activities of daily life. There really should be some room for a physician to say, “They just got here, and we don’t know him that well. There’s something that bothers me about this person” and have the ability to watch them for at least another 24 hours. That’s how I feel.
Dr. Shenvi: In my location, it would be difficult to try to admit somebody purely for observation for delayed bleeding. I think we would get a lot of pushback on that. The reasons I might admit a patient after a fall with a negative head CT, though, are all the things that, Rob, you alluded to earlier — which are, what made them fall in the first place and were they unable to get up?
I had this happen just this week. A patient who fell couldn’t get off the ground for 12 hours, and so now she’s dehydrated and delirious with slight rhabdomyolysis. Then you’re admitting them either for the sequelae of the fall that are not related to the intracranial hemorrhage, or the fact that they are so debilitated and deconditioned that they cannot take care of themselves. They need physical therapy. Often, we will have physical and occupational therapists come see them in the ED during business hours and help make an assessment of whether they are safe to go home or whether they fall again. That can give more evidence for the need for admission.
Dr. Glatter: To bring artificial intelligence into this discussion, algorithms that are out there that say, “Push a button and the patient’s safe for discharge.” Well, this argues for a clinical gestalt and a human being to make an assessment because you can use these predictive models, which are coming and they’re going to be here soon, and they already are in some sense. Again, we have to use clinical human judgment.
Dr. Shih: I agree.
Advice for Primary Care Physicians
Dr. Glatter: What return precautions do you discuss with patients who’ve had blunt head trauma that maybe had a head CT, or even didn’t? What are the main things we’re looking for?
Dr. Shenvi: What I usually tell people is if you start to have a worse headache, nausea or vomiting, any weakness in one area of your body, or vision changes, and if there’s a family member or friend there, I’ll say, “If you notice that they’re acting differently or seem confused, come back.”
Dr. Shih: I agree with what she said, and I’m also going to add one thing. The most important part is they are trying to prevent a subsequent fall. We know that when they’ve fallen and they present to the ED, they’re at even higher risk for falling and reinjuring themselves, and that’s a population that’s already at risk.
One of the secondary studies that we published out of this project was looking at follow-up with their primary care physicians, and there were two things that we wanted to address. The first was, how often did they do it? Then, when they did do it, did their primary care physicians try to address and prevent subsequent falls?
Both the answers are actually bad. Amazingly, just over like 60% followed up.
In some of our subsequent research, because we’re in the midst of a randomized, controlled trial where we do a home visit, when we initially see these individuals that have fallen, they’ll schedule a home visit for us. Then a week or two later, when we schedule the home visit, many of them cancel because they think, Oh, that was a one-off and it’s not going to happen again. Part of the problem is the patients, because many of them believe that they just slipped and fell and it’s not going to happen again, or they’re not prone to it.
The second issue was when patients did go to a primary care physician, we have found that some primary care physicians believe that falling and injuring themselves is just part of the normal aging process. A percentage of them don’t go over assessment for fall risk or even initiate fall prevention treatments or programs.
I try to take that time to tell them that this is very common in their age group, and believe it or not, a fall from standing is the way people really injure themselves, and there may be ways to prevent subsequent falls and injuries.
Dr. Glatter: Absolutely. Do you find that their medications are a contributor in some sense? Say they’re antihypertensive, have issues of orthostasis, or a new medication was added in the last week.
Dr. Shenvi: It’s all of the above. Sometimes it’s one thing, like they just started tamsulosin for their kidney stone, they stood up, they felt lightheaded, and they fell. Usually, it’s multifactorial with some changes in their gait, vision, balance, reflex time, and strength, plus the medications or the need for assistive devices. Maybe they can’t take care of their home as well as they used to and there are things on the floor. It’s really all of the above.
‘Harder to Unlearn Something Than to Learn It’
Dr. Glatter: Would either of you like to add any additional points to the discussion or add a few pearls?
Dr. Shenvi: This just highlights the challenge of how it’s harder to unlearn something than to learn it, where one study that maybe wasn’t quite looking at what we needed to, or practice and prescribing patterns have changed, so it’s no longer really relevant.
The things that we learned from that, or the fears that we instilled in our minds of, Uh oh, they could go home and have delayed bleeding, are much harder to unlearn, and it takes more studies to unlearn that idea than it did to actually put it into place.
I’m glad that your team has done this much larger, prospective study and hopefully will reduce the concern about this entity.
Dr. Shih: I appreciate that segue. It is amazing that, for paramedics and medical students, the first thing out of their mouth is, “Are they on an anticoagulant?”
In terms of the risk of developing an intracranial hemorrhage, I think it’s much less than the weight we’ve put on it before. However, I believe if they have a bleed, the bleeds are worse. It’s kind of a double-edged sword. It’s still an important factor, but it doesn’t come with the Oh my gosh, they’re on an anticoagulant that everybody thinks about.
No. 1 Cause of Traumatic Injury Is a Fall from Standing
Dr. Glatter: These are obviously ground-level falls in most patients and not motor vehicle crashes. That’s an important part in the population that you looked at that should be mentioned clearly.
Dr. Shih: It’s astonishing. I’ve been a program director for over 20 years, and geriatrics is not well taught in the curriculum. It’s astonishing for many of our trainees and emergency physicians in general that the number-one cause for traumatic injury is a fall from standing.
Certainly, we get patients coming in the trauma center like a 95-year-old person who’s on a ladder putting up his Christmas lights. I’m like, oh my God.
For the vast majority, it’s closer to 90%, but in our study, for the patients we looked at, it was 80% that fall from standing. That’s the mechanism that causes these bleeds and these major injuries.
Dr. Shenvi: That’s reflective of what we see, so it’s good that that’s what you looked at also.
Dr. Glatter: Absolutely. Well, thank you both. This has been a very informative discussion. I appreciate your time, and our readers will certainly benefit from your knowledge and expertise. Thank you again.

Because of that, a number of people across the country wanted to verify those findings from the Menditto study. We tried to design a good study to answer that question. We happen to have a very large geriatric population in Florida, and our ED census is very high for age over 65, at nearly 60%.
There are two Level I trauma centers in Palm Beach County. We included a second multicenter hospital, and we prospectively enrolled patients. We know the current state of practice is not to routinely do second CTs, so we followed these patients over time and followed their medical records to try to identify delayed bleeding. That’s how we set up our methodology.
Is It Safe to Discharge Patients With Trauma After 24 Hours?
Dr. Glatter: For the bulk of these patients with negative head CTs, it’s been my practice that when they’re stable and they look fine and there’s no other apparent, distracting painful trauma, injuries and so forth, they’re safe to discharge.
The secondary outcome in your study is interesting: the need for neurosurgical intervention in terms of those with delayed intracranial hemorrhage.
Dr. Shih: I do believe that it’s certainly not the problem that Menditto described, which is 7%. There are two other prospective studies that have looked at this issue with delayed bleeding on anticoagulants. Both of these also showed a relatively low rate of delayed bleeding, which is between like 0.2% and 1.0%. In our study, it was 0.4%.
The difference in the studies is that Menditto and colleagues routinely did 24-hour head CTs. They admitted everybody. For these other studies, routine head CT was not part of it. My bet is that there is a rate of delayed bleeding somewhere in between that seen in the Menditto study and that in all the other studies.
However, talking about significant intracranial hemorrhage, ones that perhaps need neurosurgery, I believe most of them are not significant. There’s some number that do occur, but the vast majority of those probably don’t need neurosurgery. We had 14 delayed bleeds out of 6000 patients with head trauma. One of them ended up requiring neurosurgery, so the answer is not zero, but I don’t think it’s 7% either.
Dr. Glatter: Dr. Shenvi, I want to bring you into the conversation to talk about your experience at UNC, and how you run things in terms of older patients with blunt head trauma on preinjury anticoagulants.
Dr. Shenvi: Thanks, Rob. I remember when this paper came out showing this 7% rate of delayed bleeding and the question was, “Should we be admitting all these people?” Partly just from an overwhelming need for capacity that that would bring, it just wasn’t practical to say, “We’re going to admit every patient with a negative head CT to the hospital and rescan them.” That would be hundreds or thousands of patients each year in any given facility.
The other thing is that delayed bleeds don’t always happen just in the first 24 hours. It’s not even a matter of bringing patients into observation for 24 hours, watching them, and rescanning them if they have symptoms. It can occur several days out. That never, in almost any institution that I know of, became standard practice.
The way that it did change my care was to give good return precautions to patients, to make sure they have somebody with them to say, “Hey, sometimes you can have bleeding several days out after a fall, even though your CT scan here today looks perfect,” and to alert them that if they start having severe headaches, vomiting, or other symptoms of intracranial hemorrhage, that they should come back.
I don’t think it ever became standard practice, and for good reason, because that was one study. The subsequent studies that Richard mentioned, pretty quickly on the heels of that initial one, showed a much lower rate of delayed ICH with the caveats that the methodology was different.
Shift in Anticoagulants
Dr. Shenvi: One other big change from that original study, and now to Richard’s study, is the shift in anticoagulants. Back in the initial study you mentioned, it was all warfarin. We know from other studies looking at warfarin vs the direct oral anticoagulants (DOACs) that DOACs have lower rates of ICH after a head injury, lower rates of need for neurosurgical intervention, and lower rates of discharge to a skilled nursing facility after an intracranial hemorrhage.
Across the board, we know that the DOACs tend to do better. It’s difficult to compare newer studies because it’s a different medication. It did inform my practice to have an awareness of delayed intracranial hemorrhage so that I warn patients more proactively.
Dr. Glatter: I haven’t seen a patient on warfarin in years. I don’t know if either of you have, but it’s all DOACs now unless there’s some other reason. That shift is quite apparent.
Dr. Shih: The problem with looking at delayed bleeding for DOACs vs warfarin is the numbers were so low. I think we had 13 people, and seven were in the no-anticoagulant group. The numbers are even lower, so it’s hard to say.
I just wanted to comment on something that Dr. Shenvi said, and I pretty much agree with everything that she said. Anticoagulants and warfarin, and that Menditto study, have a carryover effect. People group DOACs with warfarin similarly. When a patient is brought in, the first thing they talk about with head trauma is, “Oh, they’re on an anticoagulant” or “They’re not on an anticoagulant.” It’s so ingrained.
I believe that, in emergency medicine, we’re pressed for space and time and we’re not as affected by that 24-hour observation. Maybe many of our surgeons will automatically admit those patients.
I haven’t seen a guideline from the United States, but there are two international guidelines. One is from Austria from 2019, and one is from Scandinavia. Both recommended 24-hour observation if you’re on an anticoagulant.
There is a bit of controversy left over with that. Hopefully, as more and more of information, like in our study, comes out, people will be a little bit more clear about it. I don’t think there’s a need to routinely admit them.
I do want to mention that the Menditto study had such a massive impact on everybody. They pointed out one subgroup (and it’s such a small number of patients). They had seven cases of delayed bleeding; four or five of them were within that 24 hours, and a couple were diagnosed later over the next couple days.
Of those seven people, four of them had international normalized ratios (INRs) greater than 3. Of those four patients, I’ve heard people talk about this and recommend, “Okay, that’s the subgroup I would admit.” There’s a toss-up with what to do with DOAC because it’s very hard to tell whether there’s an issue, whether there are problems with their dosing, and whatever.
We actually recently looked at that. We have a much larger sample than four: close to 300 patients who were on warfarin. We looked at patients who had INRs below 3 and above 3, and we didn’t show a difference. We still don’t believe that warfarin is a big issue with delayed bleeding.
Should We Be Asking: ‘Are They on Blood Thinners?’
Dr. Shenvi: One of the interesting trends related to warfarin and the DOACs vs no anticoagulant is that as you mentioned, Dr Shih, the first question out of people’s mouths or the first piece of information emergency medical services gives you when they come in with a patient who’s had a head injury is, “Are they on blood thinners or not?”
Yet, the paradigm is shifting to say it’s not actually the blood thinners themselves that are giving older patients the higher risk for bleeding; it’s age and other comorbidities.
Certainly, if you’re on an anticoagulant and you start to bleed, your prognosis is much worse because the bleeding doesn’t stop. In terms of who has a bleeding event, there’s much less impact of anticoagulation than we used to think. That, in part, may be due to the change from warfarin to other medications.
Some of the experts I’ve talked to who have done the research on this have said, “Well, actually, warfarin was more of a marker for being much older and more frail, because it was primarily prescribed to older patients who have significant heart disease, atrial fibrillation, and so on.” It was more a marker for somebody who is at risk for an intracranial hemorrhage. There are many changes that have happened in the past 10 years with medications and also our understanding.
Challenges in Patient Follow-up
Dr. Glatter: That’s a great point. One thing, Rich, I want to ask you about is in terms of your proxy outcome assessment. When you use that at 14 and 60 days with telephone follow-up and then chart review at 60 and 90 days (because, obviously, everyone can’t get another head CT or it’s difficult to follow patients up), did you find that worked out well in your prospective cohort study, in terms of using that as a proxy, so to speak?
Dr. Shih: I would say to a certain extent. Unfortunately, we don’t have access to the patients to come back to follow up all of them, and there was obviously a large number of patients in our study.
The next best thing was that we had dedicated research assistants calling all of the patients at 14 days and 60 days. I’ve certainly read research studies where, when they call them, they get 80%-90% follow-up, but we did not achieve that.
I don’t know if people are more inundated with spam phone calls now, or the older people are just afraid of picking up their phone sometimes with all the scams and so forth. I totally understand, but in all honesty, we only had about a 30%-35% follow-up using that follow-up pathway.
Then the proxy pathway was to look at their charts at 60 and 90 days. Also, we looked at the Florida death registry, which is pretty good, and then finally, we had both Level I trauma centers in the county that we were in participating. It’s standard practice that if you have an intracranial hemorrhage at a non–Level I trauma center, you would be transferred to a Level I trauma center. That’s the protocol. I know that’s not followed 100% of the time, but that’s part of the proxy follow-up. You could criticize the study for not having closer to 90% actual contact, but that’s the best we could do.
Dr. Glatter: I think that’s admirable. Using that paradigm of what you described certainly allows the reader to understand the difficulty in assessing patients that don’t get follow-up head CT, and hardly anyone does that, as we know.
To your point of having both Level I trauma centers in the county, that makes it pretty secure. If we’re going to do a study encompassing a similar type of regional aspect, it would be similar.
Dr. Shenvi: I think your proxies, to your credit, were as good as you can get. You can never get a 100% follow-up, but you really looked at all the different avenues by which patients might present, either in the death registry or a Level I center. Well done on that aspect.
Determining When to Admit Patients for Observation
Dr. Glatter: In terms of admissions: You admit a patient, then you hear back that this patient should not have been admitted because they had a negative head CT, but you put them in anyway in the sense of delayed bleeding happening or not happening.
It’s interesting. Maybe the insurers will start looking at this in some capacity, based on your study, that because it’s so infrequent that you see delayed bleeding, that admitting someone for any reason whatsoever would be declined. Do you see that being an issue? In other words, [do you see] this leading to a pattern in terms of the payers?
Dr. Shih: Certainly, you could interpret it that way, and that would be unfortunate. The [incidence of] delayed bleeding is definitely not zero. That’s the first thing.
The second thing is that when you’re dealing with an older population, having some sense that they’re not doing well is an important contributor to trying to fully assess what’s going on — whether or not they have a bleed or whether they’re at risk for falling again and then hitting their head and causing a second bleed, and making sure they can do the activities of daily life. There really should be some room for a physician to say, “They just got here, and we don’t know him that well. There’s something that bothers me about this person” and have the ability to watch them for at least another 24 hours. That’s how I feel.
Dr. Shenvi: In my location, it would be difficult to try to admit somebody purely for observation for delayed bleeding. I think we would get a lot of pushback on that. The reasons I might admit a patient after a fall with a negative head CT, though, are all the things that, Rob, you alluded to earlier — which are, what made them fall in the first place and were they unable to get up?
I had this happen just this week. A patient who fell couldn’t get off the ground for 12 hours, and so now she’s dehydrated and delirious with slight rhabdomyolysis. Then you’re admitting them either for the sequelae of the fall that are not related to the intracranial hemorrhage, or the fact that they are so debilitated and deconditioned that they cannot take care of themselves. They need physical therapy. Often, we will have physical and occupational therapists come see them in the ED during business hours and help make an assessment of whether they are safe to go home or whether they fall again. That can give more evidence for the need for admission.
Dr. Glatter: To bring artificial intelligence into this discussion, algorithms that are out there that say, “Push a button and the patient’s safe for discharge.” Well, this argues for a clinical gestalt and a human being to make an assessment because you can use these predictive models, which are coming and they’re going to be here soon, and they already are in some sense. Again, we have to use clinical human judgment.
Dr. Shih: I agree.
Advice for Primary Care Physicians
Dr. Glatter: What return precautions do you discuss with patients who’ve had blunt head trauma that maybe had a head CT, or even didn’t? What are the main things we’re looking for?
Dr. Shenvi: What I usually tell people is if you start to have a worse headache, nausea or vomiting, any weakness in one area of your body, or vision changes, and if there’s a family member or friend there, I’ll say, “If you notice that they’re acting differently or seem confused, come back.”
Dr. Shih: I agree with what she said, and I’m also going to add one thing. The most important part is they are trying to prevent a subsequent fall. We know that when they’ve fallen and they present to the ED, they’re at even higher risk for falling and reinjuring themselves, and that’s a population that’s already at risk.
One of the secondary studies that we published out of this project was looking at follow-up with their primary care physicians, and there were two things that we wanted to address. The first was, how often did they do it? Then, when they did do it, did their primary care physicians try to address and prevent subsequent falls?
Both the answers are actually bad. Amazingly, just over like 60% followed up.
In some of our subsequent research, because we’re in the midst of a randomized, controlled trial where we do a home visit, when we initially see these individuals that have fallen, they’ll schedule a home visit for us. Then a week or two later, when we schedule the home visit, many of them cancel because they think, Oh, that was a one-off and it’s not going to happen again. Part of the problem is the patients, because many of them believe that they just slipped and fell and it’s not going to happen again, or they’re not prone to it.
The second issue was when patients did go to a primary care physician, we have found that some primary care physicians believe that falling and injuring themselves is just part of the normal aging process. A percentage of them don’t go over assessment for fall risk or even initiate fall prevention treatments or programs.
I try to take that time to tell them that this is very common in their age group, and believe it or not, a fall from standing is the way people really injure themselves, and there may be ways to prevent subsequent falls and injuries.
Dr. Glatter: Absolutely. Do you find that their medications are a contributor in some sense? Say they’re antihypertensive, have issues of orthostasis, or a new medication was added in the last week.
Dr. Shenvi: It’s all of the above. Sometimes it’s one thing, like they just started tamsulosin for their kidney stone, they stood up, they felt lightheaded, and they fell. Usually, it’s multifactorial with some changes in their gait, vision, balance, reflex time, and strength, plus the medications or the need for assistive devices. Maybe they can’t take care of their home as well as they used to and there are things on the floor. It’s really all of the above.
‘Harder to Unlearn Something Than to Learn It’
Dr. Glatter: Would either of you like to add any additional points to the discussion or add a few pearls?
Dr. Shenvi: This just highlights the challenge of how it’s harder to unlearn something than to learn it, where one study that maybe wasn’t quite looking at what we needed to, or practice and prescribing patterns have changed, so it’s no longer really relevant.
The things that we learned from that, or the fears that we instilled in our minds of, Uh oh, they could go home and have delayed bleeding, are much harder to unlearn, and it takes more studies to unlearn that idea than it did to actually put it into place.
I’m glad that your team has done this much larger, prospective study and hopefully will reduce the concern about this entity.
Dr. Shih: I appreciate that segue. It is amazing that, for paramedics and medical students, the first thing out of their mouth is, “Are they on an anticoagulant?”
In terms of the risk of developing an intracranial hemorrhage, I think it’s much less than the weight we’ve put on it before. However, I believe if they have a bleed, the bleeds are worse. It’s kind of a double-edged sword. It’s still an important factor, but it doesn’t come with the Oh my gosh, they’re on an anticoagulant that everybody thinks about.
No. 1 Cause of Traumatic Injury Is a Fall from Standing
Dr. Glatter: These are obviously ground-level falls in most patients and not motor vehicle crashes. That’s an important part in the population that you looked at that should be mentioned clearly.
Dr. Shih: It’s astonishing. I’ve been a program director for over 20 years, and geriatrics is not well taught in the curriculum. It’s astonishing for many of our trainees and emergency physicians in general that the number-one cause for traumatic injury is a fall from standing.
Certainly, we get patients coming in the trauma center like a 95-year-old person who’s on a ladder putting up his Christmas lights. I’m like, oh my God.
For the vast majority, it’s closer to 90%, but in our study, for the patients we looked at, it was 80% that fall from standing. That’s the mechanism that causes these bleeds and these major injuries.
Dr. Shenvi: That’s reflective of what we see, so it’s good that that’s what you looked at also.
Dr. Glatter: Absolutely. Well, thank you both. This has been a very informative discussion. I appreciate your time, and our readers will certainly benefit from your knowledge and expertise. Thank you again.

Robert D. Glatter, MD: Today, we’ll be discussing the results of a new study published in The Journal of Emergency Medicine, looking at the incidence of delayed intracranial hemorrhage among older patients taking preinjury anticoagulants who present to the emergency department (ED) with blunt head trauma.
Joining me today is the lead author of the study, Dr. Richard Shih, professor of emergency medicine at Florida Atlantic University. Also joining me is Dr. Christina Shenvi, associate professor of emergency medicine at the University of North Carolina (UNC) Chapel Hill, with fellowship training in geriatric emergency medicine.
Welcome to both of you.
Richard D. Shih, MD: Thanks, Rob.
Christina L. Shenvi, MD, PhD, MBA: Thanks. Pleasure to be here.
ICH Study Methodology
Dr. Glatter: It’s a pleasure to have you. Rich, this is a great study and targeted toward a population we see daily in the emergency department. I want you to describe your methodology, patient selection, and how you went about organizing your study to look at this important finding of delayed intracranial hemorrhage, especially in those on anticoagulants.
Dr. Shih: This all started for our research team when we first read the 2012 Annals of Emergency Medicine paper. The first author was Vincenzo Menditto, and he looked at a group of patients that had minor head injury, were anticoagulated, and had negative initial head CTs.
There were about 100 patients, of which about 10 of them did not consent, but they hospitalized all these patients. These were anticoagulated, negative-first head CTs. They hospitalized the patients and then did a routine second CT at about 24 hours. They also followed them for a week, and it turned out a little over 7% of them had delayed head CT.
We were wondering how many delayed intracranial hemorrhages we had missed because current practice for us was that, if patients had a good physical exam, their head CT was normal, and everything looked good, we would send them home.
Because of that, a number of people across the country wanted to verify those findings from the Menditto study. We tried to design a good study to answer that question. We happen to have a very large geriatric population in Florida, and our ED census is very high for age over 65, at nearly 60%.

The second thing is that when you’re dealing with an older population, having some sense that they’re not doing well is an important contributor to trying to fully assess what’s going on — whether or not they have a bleed or whether they’re at risk for falling again and then hitting their head and causing a second bleed, and making sure they can do the activities of daily life. There really should be some room for a physician to say, “They just got here, and we don’t know him that well. There’s something that bothers me about this person” and have the ability to watch them for at least another 24 hours. That’s how I feel.
Dr. Shenvi: In my location, it would be difficult to try to admit somebody purely for observation for delayed bleeding. I think we would get a lot of pushback on that. The reasons I might admit a patient after a fall with a negative head CT, though, are all the things that, Rob, you alluded to earlier — which are, what made them fall in the first place and were they unable to get up?
I had this happen just this week. A patient who fell couldn’t get off the ground for 12 hours, and so now she’s dehydrated and delirious with slight rhabdomyolysis. Then you’re admitting them either for the sequelae of the fall that are not related to the intracranial hemorrhage, or the fact that they are so debilitated and deconditioned that they cannot take care of themselves. They need physical therapy. Often, we will have physical and occupational therapists come see them in the ED during business hours and help make an assessment of whether they are safe to go home or whether they fall again. That can give more evidence for the need for admission.
Dr. Glatter: To bring artificial intelligence into this discussion, algorithms that are out there that say, “Push a button and the patient’s safe for discharge.” Well, this argues for a clinical gestalt and a human being to make an assessment because you can use these predictive models, which are coming and they’re going to be here soon, and they already are in some sense. Again, we have to use clinical human judgment.
Dr. Shih: I agree.
Advice for Primary Care Physicians
Dr. Glatter: What return precautions do you discuss with patients who’ve had blunt head trauma that maybe had a head CT, or even didn’t? What are the main things we’re looking for?
Dr. Shenvi: What I usually tell people is if you start to have a worse headache, nausea or vomiting, any weakness in one area of your body, or vision changes, and if there’s a family member or friend there, I’ll say, “If you notice that they’re acting differently or seem confused, come back.”
Dr. Shih: I agree with what she said, and I’m also going to add one thing. The most important part is they are trying to prevent a subsequent fall. We know that when they’ve fallen and they present to the ED, they’re at even higher risk for falling and reinjuring themselves, and that’s a population that’s already at risk.
One of the secondary studies that we published out of this project was looking at follow-up with their primary care physicians, and there were two things that we wanted to address. The first was, how often did they do it? Then, when they did do it, did their primary care physicians try to address and prevent subsequent falls?
Both the answers are actually bad. Amazingly, just over like 60% followed up.
In some of our subsequent research, because we’re in the midst of a randomized, controlled trial where we do a home visit, when we initially see these individuals that have fallen, they’ll schedule a home visit for us. Then a week or two later, when we schedule the home visit, many of them cancel because they think, Oh, that was a one-off and it’s not going to happen again. Part of the problem is the patients, because many of them believe that they just slipped and fell and it’s not going to happen again, or they’re not prone to it.
The second issue was when patients did go to a primary care physician, we have found that some primary care physicians believe that falling and injuring themselves is just part of the normal aging process. A percentage of them don’t go over assessment for fall risk or even initiate fall prevention treatments or programs.
I try to take that time to tell them that this is very common in their age group, and believe it or not, a fall from standing is the way people really injure themselves, and there may be ways to prevent subsequent falls and injuries.
Dr. Glatter: Absolutely. Do you find that their medications are a contributor in some sense? Say they’re antihypertensive, have issues of orthostasis, or a new medication was added in the last week.
Dr. Shenvi: It’s all of the above. Sometimes it’s one thing, like they just started tamsulosin for their kidney stone, they stood up, they felt lightheaded, and they fell. Usually, it’s multifactorial with some changes in their gait, vision, balance, reflex time, and strength, plus the medications or the need for assistive devices. Maybe they can’t take care of their home as well as they used to and there are things on the floor. It’s really all of the above.
‘Harder to Unlearn Something Than to Learn It’
Dr. Glatter: Would either of you like to add any additional points to the discussion or add a few pearls?
Dr. Shenvi: This just highlights the challenge of how it’s harder to unlearn something than to learn it, where one study that maybe wasn’t quite looking at what we needed to, or practice and prescribing patterns have changed, so it’s no longer really relevant.
The things that we learned from that, or the fears that we instilled in our minds of, Uh oh, they could go home and have delayed bleeding, are much harder to unlearn, and it takes more studies to unlearn that idea than it did to actually put it into place.
I’m glad that your team has done this much larger, prospective study and hopefully will reduce the concern about this entity.
Dr. Shih: I appreciate that segue. It is amazing that, for paramedics and medical students, the first thing out of their mouth is, “Are they on an anticoagulant?”
In terms of the risk of developing an intracranial hemorrhage, I think it’s much less than the weight we’ve put on it before. However, I believe if they have a bleed, the bleeds are worse. It’s kind of a double-edged sword. It’s still an important factor, but it doesn’t come with the Oh my gosh, they’re on an anticoagulant that everybody thinks about.
No. 1 Cause of Traumatic Injury Is a Fall from Standing
Dr. Glatter: These are obviously ground-level falls in most patients and not motor vehicle crashes. That’s an important part in the population that you looked at that should be mentioned clearly.
Dr. Shih: It’s astonishing. I’ve been a program director for over 20 years, and geriatrics is not well taught in the curriculum. It’s astonishing for many of our trainees and emergency physicians in general that the number-one cause for traumatic injury is a fall from standing.
Certainly, we get patients coming in the trauma center like a 95-year-old person who’s on a ladder putting up his Christmas lights. I’m like, oh my God.
For the vast majority, it’s closer to 90%, but in our study, for the patients we looked at, it was 80% that fall from standing. That’s the mechanism that causes these bleeds and these major injuries.
Dr. Shenvi: That’s reflective of what we see, so it’s good that that’s what you looked at also.
Dr. Glatter: Absolutely. Well, thank you both. This has been a very informative discussion. I appreciate your time, and our readers will certainly benefit from your knowledge and expertise. Thank you again.

In Colorectal Cancer, Donating Half a Liver Could Save Lives
This transcript has been edited for clarity.
Benjamin L. Schlechter, MD:
Dr. Dib is the director of the Hepatobiliary Surgery and Living Donor Program at Beth Israel Deaconess Medical Center here in Boston, and a Harvard Medical School faculty member.He was previously at the Pontificia Universidad Católica de Chile, a leading international institution investigating the role of liver transplant in colorectal cancer, among other diseases. Dr. Dib, before we move to our discussion, I’d like to hear a bit about your pathway to becoming a transplant surgeon. How did you end up working on colorectal cancer and liver transplants in this field?
Martin J. Dib, MD: Thank you so much, Dr. Schlechter. I am originally from Chile. I had an opportunity to come to Beth Israel Deaconess Medical Center after medical school and I did liver regeneration research at the transplant center. After that, I was lucky enough to match as a general surgery resident at Beth Israel Deaconess.
This is my alma mater and I was able to graduate as a surgeon here. You and I had some paths together. After graduating from Harvard as a surgeon, I was trained in liver transplant, abdominal transplant, surgical oncology, and hepatobiliary surgery at the University of Toronto.
I have been developing this passion for being able to transplant cancer patients and use organ transplant techniques to be able to do complex resections for cancer.
Dr. Schlechter: Let’s talk about the topic for today, which is liver transplant and colorectal cancer. I’ll be honest — this is not a very familiar topic for a lot of oncologists. There are a lot of details that I think are new to us as oncologists. We need to expand this conversation to get access to patients for this.
First and foremost, can you talk about some of the parameters for a resectable liver metastasis vs unresectable disease that would be an indication for a liver transplant?
Dr. Dib: I think this is a very interesting topic because liver transplantation for cancer is not new. Liver transplantation started in the 1960s when people started doing liver transplants for advanced liver tumors. The problem is that they were selecting patients who had very advanced — and poor tumor biology — tumors. The outcomes were not good.
It was only in 1996 when the Milan criteria started. Mazzaferro and colleagues, using strict patient selection, were able to do liver transplant for selected hepatocellular carcinoma patients. Having those excellent outcomes in selecting patients opened the field for what we now call transplant oncology, which is using selection criteria and using other methods to be able to select which patients will do well after transplantation, even with immunosuppression.
Liver transplantation for colorectal metastasis was used at the very beginning of the era of liver transplantation, but with very poor outcomes. It was abandoned because of the outcomes. It is exciting to see that after 20 years of not doing it, there was a group in Norway that started again. They are doing liver transplants for colorectal metastases (mets), but with very selected patients.
In Norway, they had a very unusual setting where they had more liver donors than patients on the list waiting for liver transplant. So they can’t share these livers and we’re all jealous, right? Every single country in the West struggles because we don’t have enough livers for the rest of the list. And they had a lot of livers to be able to transplant people.
They decided to transplant some selected patients with colorectal mets that were unresectable. And the surprise was that they found that they were able to get a 60% survival at 5 years. And so that was new. After that, in Norway, they started showing this data to other centers in the world. It wasn’t until this year that we could see not only the long-term data and long-term outcomes of using liver transplantation for unresectable colorectal mets, but also we’re now having data from a prospective clinical trial from France.
It was three countries in the prospective clinical trial: France, Belgium, and Italy. We now see that we have a little stronger data to support the use of liver transplants for unresectable colorectal mets.
Dr. Schlechter: That’s the TRANSMET study you’re referencing that was presented at ASCO in the late-breaking abstract session in 2024, and then more recently in The Lancet’s eClinicalMedicine. Both of those papers were led by René Adam. That was a cool presentation to sit through. I was in the room, and I was taking a ton of notes and there was a lot of info that came out of that.
First of all, it showed that patients who had received chemotherapy and were responding could then go on to liver transplant in that population. Impressively, 81% of the patients who were randomized to transplant received it. Frankly, that’s a big number, especially compared with the West, as you said, and in particular the US and here in New England where livers are a very precious commodity.
And even accounting for that, if you look at the intention-to-treat analysis, the 5-year overall survival in that population was 57% compared with 13% with chemotherapy. And that feels like a real number for chemotherapy. If you look at the per-protocol analysis, frankly, the numbers are higher.
It’s always a challenging assessment. What was also interesting to me was the pattern of recurrence, which in general was that recurrences were extrahepatic. So not only were patients rendered disease-free, but in general, the liver remained disease-free and only 3% of patients had liver-only recurrence and 11% had widespread metastatic disease.
The biggest group was lung metastases, at about 40%. Ultimately, they reported a progression-free survival of 17. 4 months for transplant compared with 6. 4 months with chemotherapy. On every parameter, it looks like liver transplant wins for these people. Help me out. Who are these people? How do we find these people?
What are the inclusions and exclusions for this population?
Dr. Dib: I think that’s very important. This is not a therapy that will be for every patient. These are selected patients who have liver-only unresectable colorectal mets. These are patients that don’t have any extrahepatic disease and that either the primary has been taken out already or that they have the primary present, but the plan is to take the primary and then do a liver transplantation after 3 months, hopefully after 6 months, of removing the primary.
These are patients who meet all the criteria that we have seen in terms of the best outcomes — patients that have Oslo scores of less than three. The Oslo trial, which included the SECA (Secondary Cancer)-I and SECA-II trials, basically showed that patients with a maximal tumor diameter of less than 5.5 with a pretransplant CEA (carcinoembryonic antigen) of less than 80 that do not have progression on chemotherapy, among other variables, do better. But the concept is that this is a therapy that will apply only to selected patients. That way we can continue to have adequate overall survival post-transplant that would be comparable to other diseases that we do liver transplants for.
Dr. Schlechter: Were there other biomarkers, any mutations that were included or excluded?
Dr. Dib: Yes. If you look at SECA-I, SECA-II trial outcomes, and also TRANSMET, they all say patients with BRAF mutations shouldn’t be transplanted. There are other parameters, including, for example, the site of the primary tumor. Patients with a left-sided colon primary tumor do much better than patients who have a right-sided primary tumor.
That’s not a complete contraindication, but if you look at the most updated inclusion criteria of programs, like the ones that the one that we have here at Beth Israel Deaconess and many others, the inclusion criteria protocols include patients who have only hepatic disease.
So, if there are no extrahepatic mets, the resection of the primary has been done or will be done after a multidisciplinary discussion. We want to make sure they have the absence of BRAF mutation, and that they don’t have disease progression while on chemotherapy. So hopefully we have data from enough months to be able to make sure that there’s no intrahepatic or extrahepatic progression while on chemotherapy.
And that’s including CEA and also looking at the imaging.
Dr. Schlechter: When you’re seeing a patient, how much chemo do you think they should have? What’s a good run chemotherapy-wise for these patients? Let’s say, before I refer a patient to you, how much chemo should they have? And then what should I do? Do I get a PET scan? Do I get MRI? What’s the right scanning I should do to prove there’s no extrahepatic disease before sending a patient in for consideration?
Dr. Dib: First, we need to confirm unresectability. Referring patients early is always a good measure to make sure that we’re all in agreement that it’s an unresectable patient. Having a PET scan from the very beginning is helpful because it shows the disease before doing chemotherapy.
In terms of the lines of chemotherapy, ideally in the TRANSMET trial, for example, the idea was to show tumor control for at least 3 months, with less than three lines of chemotherapy. Some patients will do that with FOLFIRI. It depends on the case.
I think some of those evaluations will need a multidisciplinary discussion. In our case, we are connected to the Norway team. We frequently talk with the Oslo team and an international community of transplant centers to get opinions on particular cases.
But I think referring patients early is a good measure. If we don’t think that they qualify, we will let the team know. We’re strictly looking at patients who have unresectable liver mets that don’t have extrahepatic disease. The idea is to do a primary tumor resection, and then get to transplantation, hopefully after 6 months. In some cases that have some concerns in terms of tumor biology, we may even extend the time from diagnosis to transplant to over 1.5 years.
Dr. Schlechter: Excellent. And what’s the experience like for these patients? In training as a resident many years ago, I saw patients with cirrhosis who went on to have a liver transplant, and that was sort of trading one disease for another. What is the posttransplant, or the remission, experience of a liver transplant for colorectal cancer like for the patient?
Dr. Dib: That’s a very important point. I think that transplantation has gotten better and better, as has chemotherapy systemic therapy. The liver transplantation experience from 20 years ago has improved dramatically. I think the quality of life of liver transplant patients after transplantation has increased quite a bit.
At Beth Israel Deaconess, we have a liver transplant program that is doing over a 100 livers a year. And when you have a high-volume center, usually the experience gets better. The time in the hospital post-transplant decreases.
In general, when we’re doing liver transplants, patients are getting extubated in the OR 30% of the time. The vast majority of patients are going home within 1 or 2 weeks. They need to have immunosuppression for the rest of their lives. We have a very good program of transplant coordinators that will help the family and the patient to live with immunosuppression and live with a transplanted organ.
But I would say that we have many, many patients, especially these patients who are not patients with cirrhosis. Their health is not as deteriorated as patients who have low MELD (model for end-stage liver disease) scores. They don’t have liver disease. They have cancer. So usually patients like that, many of them can go back to work and live a quality of life that is fairly reasonable.
Dr. Schlechter: That’s good to hear. When we hear statements like liver transplant for colon cancer, a lot of us have this picture of a much sicker population, but it’s interesting and true that the colorectal cancer population as a candidate for liver transplant is a much healthier population than the population with cirrhosis.
Let’s talk about organs and donors. Largely in the TRANSMET study, for example, that was cadaveric donors. Those were not living donors and you’ve done a lot of work on living donors. If the answer in the United States, because of limited access to organs, is going to be living donors, who are those donors?
What is that like? How do you identify them?
Dr. Dib: There’s a lot of advantages to using living donors for these patients. In any type of patient that needs a liver transplant, cadaveric donors or deceased donors is the same concept. There are two types of deceased donors: the brain-dead donors and donors after cardiac death. Those are hard to come by.
We still have 15%-20% mortality on the waiting list in the United States. We’re already still struggling to get enough donors to transplant the patients that are on the list. Now, if you add a new indication, which is unresectable colorectal mets, we need to make sure that the outcomes are equivalent to the patients who are going to be transplanted for other reasons.
Right now, for example, the 5-year overall survival of a patient with cirrhosis, or a patient with hepatocellular carcinoma, is over 80% 5-year survival. In the SECA trials and TRANSMET trial, if we do a good selection, I think we can get to 70% 5-year survival. But until we have more data, I think it’s a cautious measure to, as a field, try to use living donors and not compete with the rest of the list of patients who are already dying on the list for liver transplants.
Once we get more data, it’s going to be something that, in the transplant community, we may be able to use deceased donors. Especially deceased donors with maybe extended criteria that are not going to be used for other patients. We can do living-unrelated or living-related donations. Family members or also friends or neighbors or part of the community, even altruistic donors, can donate to a potential recipient. And that enables us to not only time the transplant in an adequate manner, because we’re able to transplant the patient early, but also time it so we can give the number of chemotherapy cycles that we want to give.
That’s a huge advantage. You don’t compete for a liver with the cadaveric waiting list of patients that are waiting for other reasons, and you can select the tumor biology very well because you know exactly when the surgery is going to be. For instance, we can say, okay, this patient has KRAS mutation, left-sided colon cancer, and has been having good tumor biology with no progression. We will wait 6 months from the primary tumor to the transplant, which is going to be 1 year from diagnosis to transplant. And we can see during that time whether they continue to have good tumor biology.
But if you have a deceased donor liver transplant, sometimes you can’t time that well and schedule it. It becomes a bit more tricky in terms of patient selection and making sure that we do this for the people who are going to benefit.
Dr. Schlechter: And how does donor matching work? Is it HLA (human leukocyte antigen) matched or ABO-matched? Who can donate when you say a living-related? For example, when we think about bone marrow transplantation, which we’re all familiar with in the oncology population, it’s an incredibly complex match process. Is this the same challenge?
Dr. Dib: No, it’s a little bit simpler. Living donors for liver transplants need to be between the ages of 18 and 60. They need to be relatively healthy, relatively fit, with a BMI hopefully less than 30, definitely less than 35. The compatibility is ABO compatibility. So, if they’re ABO-compatible, relatively young, relatively healthy, they would be a potential donor and we will go ahead and do a CT scan.
If the CT scan shows that they have a good, adequate anatomy, more than 90% of those will be good donors. I would say that out of 100 people who want to be donors, 25 of them will be adequate. One out of four people who want to save their family member and want to have this operation are able to donate half of their liver to their family member or loved one.
Dr. Schlechter: Excellent. And it’s helpful to know that the matching process is simpler. During his discussion, René Adam unequivocally stated that liver transplants are a new standard of care for colorectal cancer. And I guess my question is, do you agree with this statement? How do we balance the demand for living donors and the demand for deceased donors? Especially in a time of increasing fatty liver disease and obesity, other indications for liver transplant, causes of cirrhosis, and also in an era of young-onset colorectal cancer. Patients are younger. Is this a new standard of care? Do you agree with that statement?
Dr. Dib: I do agree with that statement. I think it’s important to understand that not all patients with colorectal mets are the same. Of the number of patients in the United States who have colorectal cancer, let’s say 50% of them will have liver metastasis. Only 15%-20% of them will have liver-only metastasis.
This is only for patients who have liver-only metastasis without extrahepatic disease. And only maybe 15%-20% of them will meet all the criteria to be able to undergo liver transplantation. I think it’s for a very selective subset of patients who have very good tumor biology, generally young patients who don’t have any other alternative to having even a complex liver resection and are not able to get R0 resection. That is when we could think about doing liver transplantation.
It’s one more of the skills that we can have. It doesn’t mean that it will be the only skill, or the best skill, for all of the patients.
Dr. Schlechter: When a patient volunteers to be a living donor for a loved one or a family member, and they go through all the screening and they’re found to be a candidate, what is the surgical experience for that patient?
How long are they in the hospital? What sort of operation is that?
Dr. Dib: Living donors are very special patients. These are patients who do not need an operation. And the only reason they’re doing this is to save the life of their loved one. Donor safety is our priority number one, two, three, and four. The donor operation needs to be perfect.
And so we take good care of, first of all, selecting the living donors, making sure that they’re young and they don’t have any big contraindications. We also ensure that they are well informed of the process. The living donor surgery that we’re now doing is laparoscopic and minimally invasive. Here at Beth Israel Deaconess, we have done it laparoscopically with very good results.
I think that experience before and after the surgery gets so much better because of the better recovery. They’re able to go home, in general, within 4 or 5 days, and they get on with their normal life within 6-8 weeks. I think it’s important for them to know all the processes and the actual risks and benefits for the recipient.
Among those risks, I think it’s important for them to understand that this is a complex operation. Even if we do it laparoscopically or robotically, so that the scar is less, inside we’re still taking out half of the liver. That is a surgery that needs to be undertaken very meticulously, with a focus on minimizing any bleeding.
It’s a surgery that takes a long time. It takes about 6 hours. We do our best to try to minimize any risks.
Dr. Schlechter: Excellent. Thanks for that. Today we had Dr. Martin Dib joining us to discuss liver transplant for metastatic colorectal cancer. We discussed the various important criteria. We discussed that early referral to multidisciplinary centers that manage these is important to help get patients set up.
We discussed the fact that there are certain inclusion and exclusion criteria to consider. Obviously, unresectable disease is a critical determination that should be made by a liver surgeon. The absence of extrahepatic disease is important in staging with PET or other imaging. We discussed certain other biological exclusions.
There’s a relative contraindication of right-sided vs left-sided cancers, but right-sided cancers can be transplanted. We discussed that an elevated CEA greater than 80 is a contraindication, as are mutations in BRAF. We reviewed data from both the TRANSMET trial recently published in The Lancet and presented at ASCO in 2024, as well as the older Oslo criteria and Oslo trials and SECA trials.
And finally, we heard that donors can now come as living donors, a laparoscopic robotic surgery with a better safety profile, and greater access to organs that are ABO matched and not HLA matched because of the nature of the biology. Thank you again for joining us.

The biggest group was lung metastases, at about 40%. Ultimately, they reported a progression-free survival of 17. 4 months for transplant compared with 6. 4 months with chemotherapy. On every parameter, it looks like liver transplant wins for these people. Help me out. Who are these people? How do we find these people?
What are the inclusions and exclusions for this population?
Dr. Dib: I think that’s very important. This is not a therapy that will be for every patient. These are selected patients who have liver-only unresectable colorectal mets. These are patients that don’t have any extrahepatic disease and that either the primary has been taken out already or that they have the primary present, but the plan is to take the primary and then do a liver transplantation after 3 months, hopefully after 6 months, of removing the primary.
These are patients who meet all the criteria that we have seen in terms of the best outcomes — patients that have Oslo scores of less than three. The Oslo trial, which included the SECA (Secondary Cancer)-I and SECA-II trials, basically showed that patients with a maximal tumor diameter of less than 5.5 with a pretransplant CEA (carcinoembryonic antigen) of less than 80 that do not have progression on chemotherapy, among other variables, do better. But the concept is that this is a therapy that will apply only to selected patients. That way we can continue to have adequate overall survival post-transplant that would be comparable to other diseases that we do liver transplants for.
Dr. Schlechter: Were there other biomarkers, any mutations that were included or excluded?
Dr. Dib: Yes. If you look at SECA-I, SECA-II trial outcomes, and also TRANSMET, they all say patients with BRAF mutations shouldn’t be transplanted. There are other parameters, including, for example, the site of the primary tumor. Patients with a left-sided colon primary tumor do much better than patients who have a right-sided primary tumor.
That’s not a complete contraindication, but if you look at the most updated inclusion criteria of programs, like the ones that the one that we have here at Beth Israel Deaconess and many others, the inclusion criteria protocols include patients who have only hepatic disease.
So, if there are no extrahepatic mets, the resection of the primary has been done or will be done after a multidisciplinary discussion. We want to make sure they have the absence of BRAF mutation, and that they don’t have disease progression while on chemotherapy. So hopefully we have data from enough months to be able to make sure that there’s no intrahepatic or extrahepatic progression while on chemotherapy.
And that’s including CEA and also looking at the imaging.
Dr. Schlechter: When you’re seeing a patient, how much chemo do you think they should have? What’s a good run chemotherapy-wise for these patients? Let’s say, before I refer a patient to you, how much chemo should they have? And then what should I do? Do I get a PET scan? Do I get MRI? What’s the right scanning I should do to prove there’s no extrahepatic disease before sending a patient in for consideration?
Dr. Dib: First, we need to confirm unresectability. Referring patients early is always a good measure to make sure that we’re all in agreement that it’s an unresectable patient. Having a PET scan from the very beginning is helpful because it shows the disease before doing chemotherapy.
In terms of the lines of chemotherapy, ideally in the TRANSMET trial, for example, the idea was to show tumor control for at least 3 months, with less than three lines of chemotherapy. Some patients will do that with FOLFIRI. It depends on the case.
I think some of those evaluations will need a multidisciplinary discussion. In our case, we are connected to the Norway team. We frequently talk with the Oslo team and an international community of transplant centers to get opinions on particular cases.
But I think referring patients early is a good measure. If we don’t think that they qualify, we will let the team know. We’re strictly looking at patients who have unresectable liver mets that don’t have extrahepatic disease. The idea is to do a primary tumor resection, and then get to transplantation, hopefully after 6 months. In some cases that have some concerns in terms of tumor biology, we may even extend the time from diagnosis to transplant to over 1.5 years.
Dr. Schlechter: Excellent. And what’s the experience like for these patients? In training as a resident many years ago, I saw patients with cirrhosis who went on to have a liver transplant, and that was sort of trading one disease for another. What is the posttransplant, or the remission, experience of a liver transplant for colorectal cancer like for the patient?
Dr. Dib: That’s a very important point. I think that transplantation has gotten better and better, as has chemotherapy systemic therapy. The liver transplantation experience from 20 years ago has improved dramatically. I think the quality of life of liver transplant patients after transplantation has increased quite a bit.
At Beth Israel Deaconess, we have a liver transplant program that is doing over a 100 livers a year. And when you have a high-volume center, usually the experience gets better. The time in the hospital post-transplant decreases.
In general, when we’re doing liver transplants, patients are getting extubated in the OR 30% of the time. The vast majority of patients are going home within 1 or 2 weeks. They need to have immunosuppression for the rest of their lives. We have a very good program of transplant coordinators that will help the family and the patient to live with immunosuppression and live with a transplanted organ.
But I would say that we have many, many patients, especially these patients who are not patients with cirrhosis. Their health is not as deteriorated as patients who have low MELD (model for end-stage liver disease) scores. They don’t have liver disease. They have cancer. So usually patients like that, many of them can go back to work and live a quality of life that is fairly reasonable.
Dr. Schlechter: That’s good to hear. When we hear statements like liver transplant for colon cancer, a lot of us have this picture of a much sicker population, but it’s interesting and true that the colorectal cancer population as a candidate for liver transplant is a much healthier population than the population with cirrhosis.
Let’s talk about organs and donors. Largely in the TRANSMET study, for example, that was cadaveric donors. Those were not living donors and you’ve done a lot of work on living donors. If the answer in the United States, because of limited access to organs, is going to be living donors, who are those donors?
What is that like? How do you identify them?
Dr. Dib: There’s a lot of advantages to using living donors for these patients. In any type of patient that needs a liver transplant, cadaveric donors or deceased donors is the same concept. There are two types of deceased donors: the brain-dead donors and donors after cardiac death. Those are hard to come by.
We still have 15%-20% mortality on the waiting list in the United States. We’re already still struggling to get enough donors to transplant the patients that are on the list. Now, if you add a new indication, which is unresectable colorectal mets, we need to make sure that the outcomes are equivalent to the patients who are going to be transplanted for other reasons.
Right now, for example, the 5-year overall survival of a patient with cirrhosis, or a patient with hepatocellular carcinoma, is over 80% 5-year survival. In the SECA trials and TRANSMET trial, if we do a good selection, I think we can get to 70% 5-year survival. But until we have more data, I think it’s a cautious measure to, as a field, try to use living donors and not compete with the rest of the list of patients who are already dying on the list for liver transplants.
Once we get more data, it’s going to be something that, in the transplant community, we may be able to use deceased donors. Especially deceased donors with maybe extended criteria that are not going to be used for other patients. We can do living-unrelated or living-related donations. Family members or also friends or neighbors or part of the community, even altruistic donors, can donate to a potential recipient. And that enables us to not only time the transplant in an adequate manner, because we’re able to transplant the patient early, but also time it so we can give the number of chemotherapy cycles that we want to give.
That’s a huge advantage. You don’t compete for a liver with the cadaveric waiting list of patients that are waiting for other reasons, and you can select the tumor biology very well because you know exactly when the surgery is going to be. For instance, we can say, okay, this patient has KRAS mutation, left-sided colon cancer, and has been having good tumor biology with no progression. We will wait 6 months from the primary tumor to the transplant, which is going to be 1 year from diagnosis to transplant. And we can see during that time whether they continue to have good tumor biology.
But if you have a deceased donor liver transplant, sometimes you can’t time that well and schedule it. It becomes a bit more tricky in terms of patient selection and making sure that we do this for the people who are going to benefit.
Dr. Schlechter: And how does donor matching work? Is it HLA (human leukocyte antigen) matched or ABO-matched? Who can donate when you say a living-related? For example, when we think about bone marrow transplantation, which we’re all familiar with in the oncology population, it’s an incredibly complex match process. Is this the same challenge?
Dr. Dib: No, it’s a little bit simpler. Living donors for liver transplants need to be between the ages of 18 and 60. They need to be relatively healthy, relatively fit, with a BMI hopefully less than 30, definitely less than 35. The compatibility is ABO compatibility. So, if they’re ABO-compatible, relatively young, relatively healthy, they would be a potential donor and we will go ahead and do a CT scan.
If the CT scan shows that they have a good, adequate anatomy, more than 90% of those will be good donors. I would say that out of 100 people who want to be donors, 25 of them will be adequate. One out of four people who want to save their family member and want to have this operation are able to donate half of their liver to their family member or loved one.
Dr. Schlechter: Excellent. And it’s helpful to know that the matching process is simpler. During his discussion, René Adam unequivocally stated that liver transplants are a new standard of care for colorectal cancer. And I guess my question is, do you agree with this statement? How do we balance the demand for living donors and the demand for deceased donors? Especially in a time of increasing fatty liver disease and obesity, other indications for liver transplant, causes of cirrhosis, and also in an era of young-onset colorectal cancer. Patients are younger. Is this a new standard of care? Do you agree with that statement?
Dr. Dib: I do agree with that statement. I think it’s important to understand that not all patients with colorectal mets are the same. Of the number of patients in the United States who have colorectal cancer, let’s say 50% of them will have liver metastasis. Only 15%-20% of them will have liver-only metastasis.
This is only for patients who have liver-only metastasis without extrahepatic disease. And only maybe 15%-20% of them will meet all the criteria to be able to undergo liver transplantation. I think it’s for a very selective subset of patients who have very good tumor biology, generally young patients who don’t have any other alternative to having even a complex liver resection and are not able to get R0 resection. That is when we could think about doing liver transplantation.
It’s one more of the skills that we can have. It doesn’t mean that it will be the only skill, or the best skill, for all of the patients.
Dr. Schlechter: When a patient volunteers to be a living donor for a loved one or a family member, and they go through all the screening and they’re found to be a candidate, what is the surgical experience for that patient?
How long are they in the hospital? What sort of operation is that?
Dr. Dib: Living donors are very special patients. These are patients who do not need an operation. And the only reason they’re doing this is to save the life of their loved one. Donor safety is our priority number one, two, three, and four. The donor operation needs to be perfect.
And so we take good care of, first of all, selecting the living donors, making sure that they’re young and they don’t have any big contraindications. We also ensure that they are well informed of the process. The living donor surgery that we’re now doing is laparoscopic and minimally invasive. Here at Beth Israel Deaconess, we have done it laparoscopically with very good results.
I think that experience before and after the surgery gets so much better because of the better recovery. They’re able to go home, in general, within 4 or 5 days, and they get on with their normal life within 6-8 weeks. I think it’s important for them to know all the processes and the actual risks and benefits for the recipient.
Among those risks, I think it’s important for them to understand that this is a complex operation. Even if we do it laparoscopically or robotically, so that the scar is less, inside we’re still taking out half of the liver. That is a surgery that needs to be undertaken very meticulously, with a focus on minimizing any bleeding.
It’s a surgery that takes a long time. It takes about 6 hours. We do our best to try to minimize any risks.
Dr. Schlechter: Excellent. Thanks for that. Today we had Dr. Martin Dib joining us to discuss liver transplant for metastatic colorectal cancer. We discussed the various important criteria. We discussed that early referral to multidisciplinary centers that manage these is important to help get patients set up.
We discussed the fact that there are certain inclusion and exclusion criteria to consider. Obviously, unresectable disease is a critical determination that should be made by a liver surgeon. The absence of extrahepatic disease is important in staging with PET or other imaging. We discussed certain other biological exclusions.
There’s a relative contraindication of right-sided vs left-sided cancers, but right-sided cancers can be transplanted. We discussed that an elevated CEA greater than 80 is a contraindication, as are mutations in BRAF. We reviewed data from both the TRANSMET trial recently published in The Lancet and presented at ASCO in 2024, as well as the older Oslo criteria and Oslo trials and SECA trials.
And finally, we heard that donors can now come as living donors, a laparoscopic robotic surgery with a better safety profile, and greater access to organs that are ABO matched and not HLA matched because of the nature of the biology. Thank you again for joining us.

Benjamin L. Schlechter, MD:
Dr. Dib is the director of the Hepatobiliary Surgery and Living Donor Program at Beth Israel Deaconess Medical Center here in Boston, and a Harvard Medical School faculty member.He was previously at the Pontificia Universidad Católica de Chile, a leading international institution investigating the role of liver transplant in colorectal cancer, among other diseases. Dr. Dib, before we move to our discussion, I’d like to hear a bit about your pathway to becoming a transplant surgeon. How did you end up working on colorectal cancer and liver transplants in this field?
Martin J. Dib, MD: Thank you so much, Dr. Schlechter. I am originally from Chile. I had an opportunity to come to Beth Israel Deaconess Medical Center after medical school and I did liver regeneration research at the transplant center. After that, I was lucky enough to match as a general surgery resident at Beth Israel Deaconess.
This is my alma mater and I was able to graduate as a surgeon here. You and I had some paths together. After graduating from Harvard as a surgeon, I was trained in liver transplant, abdominal transplant, surgical oncology, and hepatobiliary surgery at the University of Toronto.
I have been developing this passion for being able to transplant cancer patients and use organ transplant techniques to be able to do complex resections for cancer.
Dr. Schlechter: Let’s talk about the topic for today, which is liver transplant and colorectal cancer. I’ll be honest — this is not a very familiar topic for a lot of oncologists. There are a lot of details that I think are new to us as oncologists. We need to expand this conversation to get access to patients for this.
First and foremost, can you talk about some of the parameters for a resectable liver metastasis vs unresectable disease that would be an indication for a liver transplant?
Dr. Dib: I think this is a very interesting topic because liver transplantation for cancer is not new. Liver transplantation started in the 1960s when people started doing liver transplants for advanced liver tumors. The problem is that they were selecting patients who had very advanced — and poor tumor biology — tumors. The outcomes were not good.
It was only in 1996 when the Milan criteria started. Mazzaferro and colleagues, using strict patient selection, were able to do liver transplant for selected hepatocellular carcinoma patients. Having those excellent outcomes in selecting patients opened the field for what we now call transplant oncology, which is using selection criteria and using other methods to be able to select which patients will do well after transplantation, even with immunosuppression.
Liver transplantation for colorectal metastasis was used at the very beginning of the era of liver transplantation, but with very poor outcomes. It was abandoned because of the outcomes. It is exciting to see that after 20 years of not doing it, there was a group in Norway that started again. They are doing liver transplants for colorectal metastases (mets), but with very selected patients.
In Norway, they had a very unusual setting where they had more liver donors than patients on the list waiting for liver transplant. So they can’t share these livers and we’re all jealous, right? Every single country in the West struggles because we don’t have enough livers for the rest of the list. And they had a lot of livers to be able to transplant people.
They decided to transplant some selected patients with colorectal mets that were unresectable. And the surprise was that they found that they were able to get a 60% survival at 5 years. And so that was new. After that, in Norway, they started showing this data to other centers in the world. It wasn’t until this year that we could see not only the long-term data and long-term outcomes of using liver transplantation for unresectable colorectal mets, but also we’re now having data from a prospective clinical trial from France.
It was three countries in the prospective clinical trial: France, Belgium, and Italy. We now see that we have a little stronger data to support the use of liver transplants for unresectable colorectal mets.
Dr. Schlechter: That’s the TRANSMET study you’re referencing that was presented at ASCO in the late-breaking abstract session in 2024, and then more recently in The Lancet’s eClinicalMedicine. Both of those papers were led by René Adam. That was a cool presentation to sit through. I was in the room, and I was taking a ton of notes and there was a lot of info that came out of that.
First of all, it showed that patients who had received chemotherapy and were responding could then go on to liver transplant in that population. Impressively, 81% of the patients who were randomized to transplant received it. Frankly, that’s a big number, especially compared with the West, as you said, and in particular the US and here in New England where livers are a very precious commodity.
And even accounting for that, if you look at the intention-to-treat analysis, the 5-year overall survival in that population was 57% compared with 13% with chemotherapy. And that feels like a real number for chemotherapy. If you look at the per-protocol analysis, frankly, the numbers are higher.
It’s always a challenging assessment. What was also interesting to me was the pattern of recurrence, which in general was that recurrences were extrahepatic. So not only were patients rendered disease-free, but in general, the liver remained disease-free and only 3% of patients had liver-only recurrence and 11% had widespread metastatic disease.
The biggest group was lung metastases, at about 40%. Ultimately, they reported a progression-free survival of 17. 4 months for transplant compared with 6. 4 months with chemotherapy. On every parameter, it looks like liver transplant wins for these people. Help me out. Who are these people? How do we find these people?
What are the inclusions and exclusions for this population?

But the concept is that this is a therapy that will apply only to selected patients. That way we can continue to have adequate overall survival post-transplant that would be comparable to other diseases that we do liver transplants for.

So, if there are no extrahepatic mets, the resection of the primary has been done or will be done after a multidisciplinary discussion. We want to make sure they have the absence of BRAF mutation, and that they don’t have disease progression while on chemotherapy. So hopefully we have data from enough months to be able to make sure that there’s no intrahepatic or extrahepatic progression while on chemotherapy.
And that’s including CEA and also looking at the imaging.

We discussed the fact that there are certain inclusion and exclusion criteria to consider. Obviously, unresectable disease is a critical determination that should be made by a liver surgeon. The absence of extrahepatic disease is important in staging with PET or other imaging. We discussed certain other biological exclusions.
There’s a relative contraindication of right-sided vs left-sided cancers, but right-sided cancers can be transplanted. We discussed that an elevated CEA greater than 80 is a contraindication, as are mutations in BRAF. We reviewed data from both the TRANSMET trial recently published in The Lancet and presented at ASCO in 2024, as well as the older Oslo criteria and Oslo trials and SECA trials.
And finally, we heard that donors can now come as living donors, a laparoscopic robotic surgery with a better safety profile, and greater access to organs that are ABO matched and not HLA matched because of the nature of the biology. Thank you again for joining us.

The Wellness Industry: Financially Toxic, Says Ethicist
This transcript has been edited for clarity.
Hi. I’m Art Caplan. I’m at the Division of Medical Ethics at the NYU Grossman School of Medicine in New York City.
We have many debates and arguments that are swirling around about the out-of-control costs of Medicare. Many people are arguing we’ve got to trim it and cut back, and many people note that we can’t just go on and on with that kind of expenditure.
People look around for savings. Rightly, we can’t go on with the prices that we’re paying. No system could. We’ll bankrupt ourselves if we don’t drive prices down.
There’s another area that is driving up cost where, despite the fact that Medicare doesn’t pay for it, we could capture resources and hopefully shift them back to things like Medicare coverage or the insurance of other efficacious procedures. That area is the wellness industry.
That’s money coming out of people’s pockets that we could hopefully aim at the payment of things that we know work, not seeing the money drain out to cover bunk, nonsense, and charlatanism.
Does any or most of this stuff work? Do anything? Help anybody? No. We are spending money on charlatans and quacks. The US Food and Drug Administration (FDA), which you might think is the agency that could step in and start to get rid of some of this nonsense, is just too overwhelmed trying to track drugs, devices, and vaccines to give much attention to the wellness industry.
What am I talking about specifically? I’m talking about everything from gut probiotics that are sold in sodas to probiotic facial creams and the Goop industry of Gwyneth Paltrow, where you have people buying things like wellness mats or vaginal eggs that are supposed to maintain gynecologic health.
We’re talking about things like PEMF, or pulse electronic magnetic fields, where you buy a machine and expose yourself to mild magnetic pulses. I went online to look them up, and the machines cost $5000-$50,000. There’s no evidence that it works. By the way, the machines are not only out there as being sold for pain relief and many other things to humans, but also they’re being sold for your pets.
That industry is completely out of control. Wellness interventions, whether it’s transcranial magnetism or all manner of supplements that are sold in health food stores, over and over again, we see a world in which wellness is promoted but no data are introduced to show that any of it helps, works, or does anybody any good.
It may not be all that harmful, but it’s certainly financially toxic to many people who end up spending good amounts of money using these things. I think doctors need to ask patients if they are using any of these things, particularly if they have chronic conditions. They’re likely, many of them, to be seduced by online advertisement to get involved with this stuff because it’s preventive or it’ll help treat some condition that they have.
The industry is out of control. We’re trying to figure out how to spend money on things we know work in medicine, and yet we continue to tolerate bunk, nonsense, quackery, and charlatanism, just letting it grow and grow and grow in terms of cost.
That’s money that could go elsewhere. That is money that is being taken out of the pockets of patients. They’re doing things that may even delay medical treatment, which won’t really help them, and they are doing things that perhaps might even interfere with medical care that really is known to be beneficial.
I think it’s time to push for more money for the FDA to regulate the wellness side. I think it’s time for the Federal Trade Commission to go after ads that promise health benefits. I think it’s time to have some honest conversations with patients: What are you using? What are you doing? Tell me about it, and here’s why I think you could probably spend your money in a better way.

SURMOUNT-OSA Results: ‘Impressive’ in Improving Sleep Apnea
This transcript has been edited for clarity.
Akshay B. Jain, MD: Welcome. I’m Dr. Akshay Jain, an endocrinologist in Vancouver, Canada, and with me is a very special guest. Today we have Dr. James Kim, a primary care physician working in Calgary, Canada. Both Dr. Kim and I were fortunate to attend the recently concluded American Diabetes Association annual conference in Orlando in June.
We thought we could share with you some of the key learnings that we found very insightful and clinically quite relevant. We were hoping to bring our own conclusion regarding what these findings were, both from a primary care perspective and an endocrinology perspective.
There were so many different studies that, frankly, it was difficult to pick them, but we handpicked a few studies we felt we could do a bit of a deeper dive on, and we’ll talk about each of these studies.
Welcome, Dr. Kim, and thanks for joining us.
James W. Kim, MBBCh, PgDip, MScCH: Thank you so much, Dr Jain. It’s a pleasure to be here.
Dr. Jain: Probably the best place to start would be with the SURMOUNT-OSA study. This was highlighted at the American Diabetes Association conference. Essentially, it looked at people who are living with obesity who also had obstructive sleep apnea.
This was a randomized controlled trial where individuals tested either got tirzepatide (trade name, Mounjaro) or placebo treatment. They looked at the change in their apnea-hypopnea index at the end of the study.
This included both people who were using CPAP machines and those who were not using CPAP machines at baseline. We do know that many individuals with sleep apnea may not use these machines.
That was a big reduction.
Dr. Kim, what’s the relevance of this study in primary care?
Dr. Kim: Oh, it’s massive. Obstructive sleep apnea is probably one of the most underdiagnosed yet huge cardiac risk factors that we tend to overlook in primary care. We sometimes say, oh, it’s just sleep apnea; what’s the big deal? We know it’s a big problem. We know that more than 50% of people with type 2 diabetes have obstructive sleep apnea, and some studies have even quoted that 90% of their population cohorts had sleep apnea. This is a big deal.
What do we know so far? We know that obstructive sleep apnea, which I’m just going to call OSA, increases the risk for hypertension, bad cholesterol, and worsening blood glucose in terms of A1c and fasting glucose, which eventually leads to myocardial infarction, arrhythmia, stroke, and eventually cardiovascular death.
We also know that people with type 2 diabetes have an increased risk for OSA. There seems to be a bidirectional relationship between diabetes and OSA. It seems like weight plays the biggest role in terms of developing OSA, and numerous studies have shown this.
Also, thankfully, some of the studies showed that weight loss improves not just OSA but also blood pressure, cholesterol, blood glucose, and insulin sensitivities. These have been fascinating. We see these patients every single day. If you think about it in your population, for 50%-90% of the patients to have OSA is a large number. If you haven’t seen a person with OSA this week, you probably missed them, very likely.
Therefore, the SURMOUNT-OSA trial was quite fascinating with, as you mentioned, 50%-60% reduction in the severity of OSA, which is very impressive. Even more impressive, I think, is that for about 50% of the patients on tirzepatide, the OSA improves so much that they may not even need to be on CPAP machines.
Those who were on CPAP may not need to be on CPAP any longer. These are huge data, especially for primary care, because as you mentioned, we see these people every single day.
Dr. Jain: Thanks for pointing that out. Clearly, it’s very clinically relevant. I think the most important takeaway for me from this study was the correlation between weight loss and AHI improvement.
Clearly, it showed that placebo had about a 6% drop in AHI, whereas there was a 60% drop in the tirzepatide group, so you can see that it’s significantly different. The placebo group did not have any significant degree of weight loss, whereas the tirzepatide group had nearly 20% weight loss. This again goes to show that there is a very close correlation between weight loss and improvement in OSA.
What’s very important to note is that we’ve seen this in the past as well. We had seen some of these data with other GLP-1 agents, but the extent of improvement that we have seen in the SURMOUNT-OSA trial is significantly more than what we’ve seen in previous studies. There is a ray of hope now where we have medical management to offer people who are living with obesity and obstructive sleep apnea.
Dr. Kim: I want to add that, from a primary care perspective, this study also showed the improvement of the sleep apnea–related symptoms as well. The biggest problem with sleep apnea — or at least what patients’ spouses complain of, is the person snoring too much; it’s a symptom.
It’s the next-day symptoms that really do disturb people, like chronic fatigue. I have numerous patients who say that, once they’ve been treated for sleep apnea, they feel like a brand-new person. They have sudden bursts of energy that they never felt before, and over 50% of these people have huge improvements in the symptoms as well.
This is a huge trial. The only thing that I wish this study included were people with mild obstructive sleep apnea who were symptomatic. I do understand that, with other studies in this population, the data have been conflicting, but it would have been really awesome if they had those patients included. However, it is still a significant study for primary care.
Dr. Jain: That’s a really good point. Fatigue improves and overall quality of life improves. That’s very important from a primary care perspective.
From an endocrinology perspective, we know that management of sleep apnea can often lead to improvement in male hypogonadism, polycystic ovary syndrome, and insulin resistance. The amount of insulin required, or the number of medications needed for managing diabetes, can improve. Hypertension can improve as well. There are multiple benefits that you can get from appropriate management of sleep apnea.
Thanks, Dr. Kim. We really appreciate your insights on SURMOUNT-OSA.

Are Beta-Blockers Needed Post MI? No, Even After the ABYSS Trial
The ABYSS trial found that interruption of beta-blocker therapy in patients after myocardial infarction (MI) was not noninferior to continuing the drugs.
I will argue why I think it is okay to stop beta-blockers after MI — despite this conclusion. The results of ABYSS are, in fact, similar to REDUCE-AMI, which compared beta-blocker use or nonuse immediately after MI, and found no difference in a composite endpoint of death or MI.
The ABYSS Trial
ABYSS investigators randomly assigned nearly 3700 patients who had MI and were prescribed a beta-blocker to either continue (control arm) or stop (active arm) the drug at 1 year.
Patients had to have a left ventricular ejection fraction (LVEF) at least 40%; the median was 60%.
The composite primary endpoint included death, MI, stroke, or hospitalization for any cardiovascular reason. ABYSS authors chose a noninferiority design. The assumption must have been that the interruption arm offered an easier option for patients — eg, fewer pills.
Over 3 years, a primary endpoint occurred in 23.8% of the interruption group vs 21.1% in the continuation group.
In ABYSS, the noninferiority margin was set at a 3% absolute risk increase. The 2.7% absolute risk increase had an upper bound of the 95% CI (worst case) of 5.5% leading to the not-noninferior conclusion (5.5% exceeds the noninferiority margins).
More simply stated, the primary outcome event rate was higher in the interruption arm.
Does This Mean we Should Continue Beta-Blockers in Post-MI Patients?
This led some to conclude that we should continue beta-blockers. I disagree. To properly interpret the ABYSS trial, you must consider trial procedures, components of the primary endpoint, and then compare ABYSS with REDUCE-AMI.
It’s also reasonable to have extremely pessimistic prior beliefs about post-MI beta-blockade because the evidence establishing benefit comes from trials conducted before urgent revascularization became the standard therapy.
ABYSS was a pragmatic open-label trial. The core problem with this design is that one of the components of the primary outcome (hospitalization for cardiovascular reasons) requires clinical judgment — and is therefore susceptible to bias, particularly in an open-label trial.
This becomes apparent when we look at the components of the primary outcome in the two arms of the trial (interrupt vs continue):
- For death, the rates were 4.1 and 4.0%
- For MI, the rates were 2.5 and 2.4%
- For stroke, the rates were 1.0% in both arms
- For CV hospitalization, the rates were 18.9% vs 16.6%
The higher rate CV hospitalization alone drove the results of ABYSS. Death, MI, and stroke rates were nearly identical.
The most common reason for admission to the hospital in this category was for angiography. In fact, the rate of angiography was 2.3% higher in the interruption arm — identical to the rate increase in the CV hospitalization component of the primary endpoint.
The results of ABYSS, therefore, were driven by higher rates of angiography in the interrupt arm.
You need not imply malfeasance to speculate that patients who had their beta-blocker stopped might be treated differently regarding hospital admissions or angiography than those who stayed on beta-blockers. Researchers from Imperial College London called such a bias in unblinded trials “subtraction anxiety and faith healing.”
Had the ABYSS investigators chosen the simpler, less bias-prone endpoints of death, MI, or stroke, their results would have been the same as REDUCE-AMI.
My Final Two Conclusions
I would conclude that interruption of beta-blockers at 1 year vs continuation in post-MI patients did not lead to an increase in death, MI, or stroke.
ABYSS, therefore, is consistent with REDUCE-AMI. Taken together, along with the pessimistic priors, these are important findings because they allow us to stop a medicine and reduce the work of being a patient.
My second conclusion concerns ways of knowing in medicine. I’ve long felt that randomized controlled trials (RCTs) are the best way to sort out causation. This idea led me to the believe that medicine should have more RCTs rather than follow expert opinion or therapeutic fashion.
I’ve now modified my love of RCTs — a little. The ABYSS trial is yet another example of the need to be super careful with their design.
Something as seemingly simple as choosing what to measure can alter the way clinicians interpret and use the data.
So, let’s have (slightly) more trials, but we should be really careful in their design. Slow and careful is the best way to practice medicine. And it’s surely the best way to do research as well.

The ABYSS trial found that interruption of beta-blocker therapy in patients after myocardial infarction (MI) was not noninferior to continuing the drugs.
I will argue why I think it is okay to stop beta-blockers after MI — despite this conclusion. The results of ABYSS are, in fact, similar to REDUCE-AMI, which compared beta-blocker use or nonuse immediately after MI, and found no difference in a composite endpoint of death or MI.
The ABYSS Trial
ABYSS investigators randomly assigned nearly 3700 patients who had MI and were prescribed a beta-blocker to either continue (control arm) or stop (active arm) the drug at 1 year.
Patients had to have a left ventricular ejection fraction (LVEF) at least 40%; the median was 60%.
The composite primary endpoint included death, MI, stroke, or hospitalization for any cardiovascular reason. ABYSS authors chose a noninferiority design. The assumption must have been that the interruption arm offered an easier option for patients — eg, fewer pills.

A New Era of Obesity Medicine
Obesity has now reached epidemic proportions, with global prevalence of the condition increasing more than threefold between 1975 and 2022. In the United States alone, roughly two in five adults have obesity. As healthcare providers are intimately aware, obesity is linked to many serious health conditions, including type 2 diabetes, cardiovascular disease, and metabolic-associated steatotic liver disease, as well as some forms of cancer. As such, it presents a major challenge to chronic disease prevention and overall health.
For many years, management of obesity was considered within the purview of primary care as part of chronic disease management. However, as obesity has become more common, our understanding of the underlying causes of obesity has improved, and optimal strategies to manage and treat obesity have evolved.
In this month’s Member Spotlight, we introduce you to gastroenterologist Dr. Janese Laster, who has built a successful career with a primary focus on obesity medicine. She shares her passionate perspective on why gastroenterologists should play a more prominent role in management of this complex, chronic disease. We also include a summary of obesity-related content presented as part of this spring’s AGA Post-Graduate Course, with helpful clinical pearls from experts Dr. Andres Acosta, Dr. Violeta Popov, Dr. Sonali Paul, and Dr. Pooja Singhal.
Also in our September issue, we highlight a recent, practice-changing randomized controlled trial from Clinical Gastroenterology and Hepatology supporting use of snare tip soft coagulation as the preferred thermal margin treatment to reduce recurrence rates following colorectal endoscopic mucosal resection. In our quarterly Perspectives column, Dr. Maggie Ham and Dr. Petr Protiva offer their insights into a pressing question on many of our minds — whether to take the 10-year “high-stakes” exam or opt for the Longitudinal Knowledge Assessment to maintain American Board of Internal Medicine certification. As always, thanks for reading and please don’t hesitate to reach out with suggestions for future coverage.
