Robert A. Harrington, MD: I’m here in London at the European Society of Cardiology meetings, at theheart.org | Medscape Cardiology booth, using the meetings as an opportunity to meet with colleagues to talk about recent things that they’ve been writing about.

Today I’m joined by a good friend and colleague, Dr. Dhruv Kazi from Beth Israel Deaconess in Boston. Thanks for joining us.

Dhruv S. Kazi, MD, MS: Thank you for having me.

Harrington: Dr. Kazi is an associate professor of medicine at Harvard Medical School. He’s also the associate director of the Smith Center, which is an outcomes research center at the Beth Israel Deaconess. Thanks for joining us.

Kazi: Excited to be here.

Harrington: The topic I think you know that I want to discuss is a really important paper. There are two papers. They’re part of the American Heart Association’s 100th anniversary celebration, if you will. Many of the papers looked back at where science taken us.

With your coauthor, Karen Joynt Maddox, your papers are looking forward. They’re about the burden of cardiovascular disease in 2050. One paper really focused on what I would call the clinical and public health issues. Yours is focused on the economics. Is that a good description?

Kazi: Perfect.

Harrington: Tell us what you, Karen, and the other writers set out to do. What were you asked to do?

Kazi: As you know, the American Heart Association is entering its second century. Part of this was an exercise to say, where will the country be in 2050, which is a long enough time horizon for us to start planning for the future. What are the conditions that affect the magnitude of the disease, and the kinds of people who will be affected, that we should be aware of?

We looked back and said, if prior trends remain the same, where will we be in 2050, accounting for changes in demographics, changes in the composition of the population, and knowing that some of the cardiovascular risk factors are getting worse?

Harrington: For me, what was really striking is that, when I first saw the title and read “2050,” I thought, Oh, that’s a long way away. Then as I started reading it, I realized that this is not so far away.

Kazi: Absolutely.

Harrington: If we’re going to make a difference, it might take us 25 years.

Kazi: Especially if we set ourselves ambitious goals, we›re going to have to dig deep. Business-as-usual is not going to get us there.

Harrington: No. What I think has happened is we›ve spent so much time taking care of acute illness. Case fatality rates are fantastic. I was actually making the comment yesterday to a colleague that when I was an intern, the 30-day death rate from acute myocardial infarction was about 20%.

Kazi: Oh, wow.

Harrington: Now it’s 5%. That’s a big difference in a career.
 

Trends in the Wrong Direction

Kazi: There are fundamental trends. The decline in case fatalities is a really positive development, and I would hope that, going forward, that would continue. Those are risk-adjusted death rates and what is happening is that risk is going up. This is a function of the fact that the US population is aging; 2030 will be the first year that all the baby boomers will be over the age of 65.

By the mid-2030s, we’ll have more adults over the age of 65 than kids. That aging of the population is going to increase risk. The second is — and this is a positive development — we are a more diverse population, but the populations that are minoritized have higher cardiovascular risk, for a variety of reasons.

As the population of Asian Americans increases and doubles, in fact, as the population of Hispanic Americans doubles, we’re going to see an increase in risk related to cardiovascular disease. The third is that, over the past decade, there are some risk factors that are going in the wrong direction.

Harrington: Let’s talk about that because that’s humbling. I’m involved, as you know, with the American Heart Association, as are you. Despite all the work on Life’s Simple 7 and now Life’s Essential 8, we still have some issues.

Kazi: The big ones that come to mind are hypertension, diabetes, and obesity, all of which are trending in the wrong direction. Hypertension, we were gaining traction; and then over the past decade, we’ve slipped again. As you know, national blood pressure control rates have declined in many populations.

Harrington: Rather substantially.

Kazi: Substantially so, which has implications, in particular, for stroke rates in the future and stroke rates in young adults in the future. Obesity is a problem that we have very little control over. We’re already at 40% on average, which means that some populations are already in the 60% range.

Harrington: We also have obesity in kids — the burden, I’ll call it, of obesity. It’s not that you become obese in your thirties or your forties; you›re becoming obese as a teenager or even younger.

Kazi: Exactly. Since the 1990s, obesity in US adults has doubled, but obesity in US children has quadrupled. It’s starting from a lower base, but it’s very much an escalating problem.

Harrington: Diabetes is tightly linked to it but not totally explained.

Kazi: Exactly. The increase in diabetes is largely driven by obesity, but it›s probably also driven by changes in diet and lifestyle that don›t go through obesity.

Harrington: Yeah, it’s interesting. I think I have this figure correctly. It used to be rare that you saw a child with type 2 diabetes or what we call type 2 diabetes.

Kazi: Yeah.

Harrington: Now, the vast majority of kids with diabetes have type 2 diabetes.

Kazi: In the adolescents/young adults age group, most of it is type 2.

Harrington: Diabetes going up, obesity up, hypertension not well controlled, smoking combustible cigarettes way down.

Kazi: Yeah.

Harrington: Cholesterol levels. I was surprised. Cholesterol looked better. You said — because I was at a meeting where somebody asked you — that’s not explained by treatment.

Kazi: No, it’s not, at least going back to the ‘70s, but likely even sooner. I think that can only be attributed to substantial dietary changes. We are consuming less fat and less trans-fat. It’s possible that those collectively are improving our cholesterol levels, possibly at the expense of our glucose levels, because we basically substituted fats in our diet with more carbs at a population level.
 

Cigarettes and Vaping

Harrington: Some things certainly trend in the right direction but others in a really difficult direction. It’s going to lead to pretty large changes in risk for coronary disease, atrial fibrillation, and heart failure.

Kazi: I want to go back to the tobacco point. There are definitely marked declines in tobacco, still tightly related to income in the country. You see much higher prevalence of tobacco use in lower-income populations, but it’s unclear to me where it’s going in kids. We know that combustible tobacco use is going down but e-cigarettes went up. What that leads to over the next 30 years is unclear to me.

Harrington: That is a really important comment that’s worth sidebarring. The vaping use has been a terrible epidemic among our high schoolers. What is that going to lead to? Is it going to lead to the use of combustible cigarettes and we’re going to see that go back up? It remains to be seen.

Kazi: Yes, it remains to be seen. Going back to your point about this change in risk factors and this change in demographics, both aging and becoming a more diverse population means that we have large increases in some healthcare conditions.

Coronary heart disease goes up some, there›s a big jump in stroke — nearly a doubling in stroke — which is related to hypertension, obesity, an aging population, and a more diverse population. There are changes in stroke in the young, and atrial fibrillation related to, again, hypertension. We’re seeing these projections, and with them come these pretty large projections in changes in healthcare spending.
 

Healthcare Spending Not Sustainable

Harrington: Big. I mean, it’s not sustainable. Give the audience the number — it’s pretty frightening.

Kazi: We’re talking about a quadrupling of healthcare costs related to cardiovascular disease over 25 years. We’ve gotten used to the narrative that healthcare in the US is expensive and drugs are expensive, but this is an enormous problem — an unsustainable problem, like you called it.

It’s a doubling as a proportion of the economy. I was looking this up this morning. If the US healthcare economy were its own economy, it would be the fourth largest economy in the world.

Harrington: Healthcare as it is today, is it 21% of our economy?

Kazi: It’s 17% now. If it were its own economy, it would be the fourth largest in the world. We are spending more on healthcare than all but two other countries’ total economies. It’s kind of crazy.

Harrington: We’re talking about a quadrupling.

Kazi: Within that, the cardiovascular piece is a big piece, and we›re talking about a quadrupling.

Harrington: That’s both direct and indirect costs.

Kazi: The quadrupling of costs is just the direct costs. Indirect costs, for the listeners, refer to costs unrelated to healthcare but changes in productivity, either because people are disabled and unable to participate fully in the workforce or they die early.

The productivity costs are also increased substantially as a result. If you look at both healthcare and productivity, that goes up threefold. These are very large changes.

Harrington: Let’s now get to what we can do about it. I made the comment to you when I first read the papers that I was very depressed. Then, after I went through my Kübler-Ross stages of depression, death, and dying, I came to acceptance.

What are we going to do about it? This is a focus on policy, but also a focus on how we deliver healthcare, how we think about healthcare, and how we develop drugs and devices.

The drug question is going to be the one the audience is thinking about. They say, well, what about GLP-1 agonists? Aren’t those going to save the day?

Kazi: Yes and no. I’ll say that, early in my career, I used to be very attracted to simple solutions to complex problems. I’ve come to realize that simple solutions are elegant, attractive, and wrong. We›re dealing with a very complex issue and I think we’re going to need a multipronged approach.

The way I think about it is that there was a group of people who are at very high risk today. How do we help those individuals? Then how do we help the future generation so that they’re not dealing with the projections that we’re talking about.

My colleague, Karen Joynt Maddox, who led one of the papers, as you mentioned, has an elegant line in the paper where she says projections are not destiny. These are things we can change.

Harrington: If nothing changes, this is what it’s going to look like.

Kazi: This is where we’re headed.

Harrington: We can change. We’ve got some time to change, but we don’t have forever.

Kazi: Yes, exactly. We picked the 25-year timeline instead of a “let’s plan for the next century” timeline because we want something concrete and actionable. It’s close enough to be meaningful but far enough to give us the runway we need to act.

Harrington: Give me two things from the policy perspective, because it’s mostly policy.

Kazi: There are policy and clinical interventions. From the policy perspective, if I had to list two things, one is expansion of access to care. As we talk about this big increase in the burden of disease and risk factors, if you have a large proportion of your population that has hypertension or diabetes, you’re going to have to expand access to care to ensure that people get treated so they can get access to this care before they develop the complications that we worry about, like stroke and heart disease, that are very expensive to treat downstream.

The second, more broadly related to access to care, is the access to medications that are effective. You bring up GLP-1s. I think we need a real strategy for how we can give people access to GLP-1s at a price that is affordable to individuals but also affordable to the health system, and to help them stay on the drugs.

GLP-1s are transformative in what they do for weight loss and for diabetes, but more than 50% of people who start one are off it at 12 months. There’s something fundamentally wrong about how we’re delivering GLP-1s today. It’s not just about the cost of the drugs but the support system people need to stay on.

Harrington: I’ve made the comment, in many forms now, that we know the drugs work. We have to figure out how to use them.

Kazi: Exactly, yes.

Harrington: Using them includes chronicity. This is a chronic condition. Some people can come off the drugs, but many can’t. We’re going to have to figure this out, and maybe the newer generations of drugs will help us address what people call the off-ramping. How are we going to do that? I think you’re spot-on. Those are critically important questions.

Kazi: As we looked at this modeling, I’ll tell you — I had a come-to-Jesus moment where I was like, there is no way to fix cardiovascular disease in the US without going through obesity and diabetes. We have to address obesity in the US. We can’t just treat our way out of it. Obesity is fundamentally a food problem and we’ve got to engage again with food policy in a meaningful way.

Harrington: As you know, with the American Heart Association, we›re doing a large amount of work now on food as medicine and food is medicine. We are trying to figure out what the levers are that we can pull to actually help people eat healthier diets.

Kazi: Yes. Rather than framing it as an individual choice that people are eating poorly, it’s, how do we make healthy diets the default in the environment?

Harrington: This is where you get to the children as well.

Kazi: Exactly.

Harrington: I could talk about this all day. I’ve had the benefit of reading the papers now a few times and talking to you on several occasions. Thank you for joining us.

Kazi: Thank you.

This is a function of the fact that the US population is aging; 2030 will be the first year that all the baby boomers will be over the age of 65.

By the mid-2030s, we’ll have more adults over the age of 65 than kids. That aging of the population is going to increase risk. The second is — and this is a positive development — we are a more diverse population, but the populations that are minoritized have higher cardiovascular risk, for a variety of reasons.

As the population of Asian Americans increases and doubles, in fact, as the population of Hispanic Americans doubles, we’re going to see an increase in risk related to cardiovascular disease. The third is that, over the past decade, there are some risk factors that are going in the wrong direction.

Harrington: Let’s talk about that because that’s humbling. I’m involved, as you know, with the American Heart Association, as are you. Despite all the work on Life’s Simple 7 and now Life’s Essential 8, we still have some issues.

Kazi: The big ones that come to mind are hypertension, diabetes, and obesity, all of which are trending in the wrong direction. Hypertension, we were gaining traction; and then over the past decade, we’ve slipped again. As you know, national blood pressure control rates have declined in many populations.

Harrington: Rather substantially.

Kazi: Substantially so, which has implications, in particular, for stroke rates in the future and stroke rates in young adults in the future. Obesity is a problem that we have very little control over. We’re already at 40% on average, which means that some populations are already in the 60% range.

Harrington: We also have obesity in kids — the burden, I’ll call it, of obesity. It’s not that you become obese in your thirties or your forties; you›re becoming obese as a teenager or even younger.

Kazi: Exactly. Since the 1990s, obesity in US adults has doubled, but obesity in US children has quadrupled. It’s starting from a lower base, but it’s very much an escalating problem.

Harrington: Diabetes is tightly linked to it but not totally explained.

Kazi: Exactly. The increase in diabetes is largely driven by obesity, but it›s probably also driven by changes in diet and lifestyle that don›t go through obesity.

Harrington: Yeah, it’s interesting. I think I have this figure correctly. It used to be rare that you saw a child with type 2 diabetes or what we call type 2 diabetes.

Kazi: Yeah.

Harrington: Now, the vast majority of kids with diabetes have type 2 diabetes.

Kazi: In the adolescents/young adults age group, most of it is type 2.

Harrington: Diabetes going up, obesity up, hypertension not well controlled, smoking combustible cigarettes way down.

Kazi: Yeah.

Harrington: Cholesterol levels. I was surprised. Cholesterol looked better. You said — because I was at a meeting where somebody asked you — that’s not explained by treatment.

Kazi: No, it’s not, at least going back to the ‘70s, but likely even sooner. I think that can only be attributed to substantial dietary changes. We are consuming less fat and less trans-fat. It’s possible that those collectively are improving our cholesterol levels, possibly at the expense of our glucose levels, because we basically substituted fats in our diet with more carbs at a population level.
 

Cigarettes and Vaping

Harrington: Some things certainly trend in the right direction but others in a really difficult direction. It’s going to lead to pretty large changes in risk for coronary disease, atrial fibrillation, and heart failure.

Kazi: I want to go back to the tobacco point. There are definitely marked declines in tobacco, still tightly related to income in the country. You see much higher prevalence of tobacco use in lower-income populations, but it’s unclear to me where it’s going in kids. We know that combustible tobacco use is going down but e-cigarettes went up. What that leads to over the next 30 years is unclear to me.

Harrington: That is a really important comment that’s worth sidebarring. The vaping use has been a terrible epidemic among our high schoolers. What is that going to lead to? Is it going to lead to the use of combustible cigarettes and we’re going to see that go back up? It remains to be seen.

Kazi: Yes, it remains to be seen. Going back to your point about this change in risk factors and this change in demographics, both aging and becoming a more diverse population means that we have large increases in some healthcare conditions.

Coronary heart disease goes up some, there›s a big jump in stroke — nearly a doubling in stroke — which is related to hypertension, obesity, an aging population, and a more diverse population. There are changes in stroke in the young, and atrial fibrillation related to, again, hypertension. We’re seeing these projections, and with them come these pretty large projections in changes in healthcare spending.
 

Healthcare Spending Not Sustainable

Harrington: Big. I mean, it’s not sustainable. Give the audience the number — it’s pretty frightening.

Kazi: We’re talking about a quadrupling of healthcare costs related to cardiovascular disease over 25 years. We’ve gotten used to the narrative that healthcare in the US is expensive and drugs are expensive, but this is an enormous problem — an unsustainable problem, like you called it.

It’s a doubling as a proportion of the economy. I was looking this up this morning. If the US healthcare economy were its own economy, it would be the fourth largest economy in the world.

Harrington: Healthcare as it is today, is it 21% of our economy?

Kazi: It’s 17% now. If it were its own economy, it would be the fourth largest in the world. We are spending more on healthcare than all but two other countries’ total economies. It’s kind of crazy.

Harrington: We’re talking about a quadrupling.

Kazi: Within that, the cardiovascular piece is a big piece, and we›re talking about a quadrupling.

Harrington: That’s both direct and indirect costs.

Kazi: The quadrupling of costs is just the direct costs. Indirect costs, for the listeners, refer to costs unrelated to healthcare but changes in productivity, either because people are disabled and unable to participate fully in the workforce or they die early.

The productivity costs are also increased substantially as a result. If you look at both healthcare and productivity, that goes up threefold. These are very large changes.

Harrington: Let’s now get to what we can do about it. I made the comment to you when I first read the papers that I was very depressed. Then, after I went through my Kübler-Ross stages of depression, death, and dying, I came to acceptance.

What are we going to do about it? This is a focus on policy, but also a focus on how we deliver healthcare, how we think about healthcare, and how we develop drugs and devices.

The drug question is going to be the one the audience is thinking about. They say, well, what about GLP-1 agonists? Aren’t those going to save the day?

Kazi: Yes and no. I’ll say that, early in my career, I used to be very attracted to simple solutions to complex problems. I’ve come to realize that simple solutions are elegant, attractive, and wrong. We›re dealing with a very complex issue and I think we’re going to need a multipronged approach.

The way I think about it is that there was a group of people who are at very high risk today. How do we help those individuals? Then how do we help the future generation so that they’re not dealing with the projections that we’re talking about.

My colleague, Karen Joynt Maddox, who led one of the papers, as you mentioned, has an elegant line in the paper where she says projections are not destiny. These are things we can change.

Harrington: If nothing changes, this is what it’s going to look like.

Kazi: This is where we’re headed.

Harrington: We can change. We’ve got some time to change, but we don’t have forever.

Kazi: Yes, exactly. We picked the 25-year timeline instead of a “let’s plan for the next century” timeline because we want something concrete and actionable. It’s close enough to be meaningful but far enough to give us the runway we need to act.

Harrington: Give me two things from the policy perspective, because it’s mostly policy.

Kazi: There are policy and clinical interventions. From the policy perspective, if I had to list two things, one is expansion of access to care. As we talk about this big increase in the burden of disease and risk factors, if you have a large proportion of your population that has hypertension or diabetes, you’re going to have to expand access to care to ensure that people get treated so they can get access to this care before they develop the complications that we worry about, like stroke and heart disease, that are very expensive to treat downstream.

The second, more broadly related to access to care, is the access to medications that are effective. You bring up GLP-1s. I think we need a real strategy for how we can give people access to GLP-1s at a price that is affordable to individuals but also affordable to the health system, and to help them stay on the drugs.

GLP-1s are transformative in what they do for weight loss and for diabetes, but more than 50% of people who start one are off it at 12 months. There’s something fundamentally wrong about how we’re delivering GLP-1s today. It’s not just about the cost of the drugs but the support system people need to stay on.

Harrington: I’ve made the comment, in many forms now, that we know the drugs work. We have to figure out how to use them.

Kazi: Exactly, yes.

Harrington: Using them includes chronicity. This is a chronic condition. Some people can come off the drugs, but many can’t. We’re going to have to figure this out, and maybe the newer generations of drugs will help us address what people call the off-ramping. How are we going to do that? I think you’re spot-on. Those are critically important questions.

Kazi: As we looked at this modeling, I’ll tell you — I had a come-to-Jesus moment where I was like, there is no way to fix cardiovascular disease in the US without going through obesity and diabetes. We have to address obesity in the US. We can’t just treat our way out of it. Obesity is fundamentally a food problem and we’ve got to engage again with food policy in a meaningful way.

Harrington: As you know, with the American Heart Association, we›re doing a large amount of work now on food as medicine and food is medicine. We are trying to figure out what the levers are that we can pull to actually help people eat healthier diets.

Kazi: Yes. Rather than framing it as an individual choice that people are eating poorly, it’s, how do we make healthy diets the default in the environment?

Harrington: This is where you get to the children as well.

Kazi: Exactly.

Harrington: I could talk about this all day. I’ve had the benefit of reading the papers now a few times and talking to you on several occasions. Thank you for joining us.

Kazi: Thank you.

TOPLINE:

Compared with six cycles, three cycles of chemotherapy for high-risk retinoblastoma showed noninferior 5-year disease-free survival (DFS). The three-cycle regimen also resulted in fewer adverse events and lower costs.

METHODOLOGY:

• The introduction of chemotherapy has increased survival rates for patients with retinoblastoma, but the optimal number of postoperative adjuvant cycles remains unclear due to scant randomized clinical trial data for high-risk patients.
• In the new trial, participants at two premier eye centers in China were randomly assigned to receive either three (n = 94) or six (n = 93) cycles of carboplatin, etoposide, and vincristine (CEV) chemotherapy after enucleation.
• The primary endpoint was 5-year DFS, and the secondary endpoints were overall survival, safety, economic burden, and quality of life.
• Patients were followed up every 3 months for the first 2 years and then every 6 months thereafter, with a median follow-up of 79 months.
• Adverse events were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0).

TAKEAWAY:

• The 5-year DFS rates were 90.4% and 89.2% for the three- and six-cycle groups, respectively, meeting the noninferiority criterion (P = .003).
• The six-cycle group experienced a higher frequency of adverse events, including neutropenia, anemia, and nausea, than the three-cycle group.
• The quality-of-life scores were higher in the three-cycle group, particularly in physical, emotional, and social functioning parameters.
• The total, direct, and indirect costs were significantly lower in the three-cycle group than in the six-cycle group.

IN PRACTICE:

“A three-cycle CEV regimen demonstrated noninferiority, compared with a six-cycle approach, and was and proved to be an efficacious adjuvant chemotherapy regimen for individuals diagnosed with pathologically high-risk retinoblastoma,” the authors of the study wrote.

In an accompanying editorial, Ning Li, MD, and colleagues wrote that the findings “could lead to changes in clinical practice, reducing treatment burden and costs without compromising patient outcomes.”
 

SOURCE:

This study was led by Huijing Ye, MD, PhD, State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University in Guangzhou, China. Both the study and editorial were published online in JAMA.

LIMITATIONS: 

The open-label design of the study might introduce bias, although an independent, blinded committee evaluated the clinical outcomes. The 12% noninferiority margin was notably substantial, considering the rarity of retinoblastoma and the wide range of survival rates. The criteria for adjuvant therapy, especially regarding choroidal invasion, were debatable and required further follow-up to clarify the prognosis related to various pathologic features.

DISCLOSURES:

This study was supported by the Sun Yat-Sen University Clinical Research 5010 Program and the Shanghai Committee of Science and Technology. No relevant conflict of interest was disclosed by the authors of the paper or the editorial.

Trying to reduce your carbohydrate intake means going against nearly a million years of evolution.

Humans are among a few species with multiple copies of certain genes that help us break down starch — carbs like potatoes, beans, corn, and grains — so that we can turn it into energy our bodies can use.

However, it’s been difficult for researchers to pinpoint when in human history we acquired multiple copies of these genes because they’re in a region of the genome that’s hard to sequence.

A recent study published in Science suggests that humans may have developed multiple copies of the gene for amylase — an enzyme that’s the first step in starch digestion — over 800,000 years ago, long before the agricultural revolution. This genetic change could have helped us adapt to eating starchy foods.

The study shows how “what your ancestors ate thousands of years ago could be affecting our genetics today,” said Kelsey Jorgensen, PhD, a biological anthropologist at The University of Kansas, Lawrence, who was not involved in the study.

The double-edged sword has sharpened over all those centuries. On one hand, the human body needs and craves carbs to function. On the other hand, our modern-day consumption of carbs, especially calorie-dense/nutritionally-barren processed carbs, has long since passed “healthy.”
 

How Researchers Found Our Carb-Lover Gene

The enzyme amylase turns complex carbs into maltose, a sweet-tasting sugar that is made of two glucose molecules linked together. We make two kinds of amylases: Salivary amylase that breaks down carbs in our mouths and pancreatic amylase that is secreted into our small intestines.

Modern humans have multiple copies of both amylases. Past research showed that human populations with diets high in starch can have up to nine copies of the gene for salivary amylase, called AMY1.

To pinpoint when in human history we acquired multiple copies of AMY1, the new study utilized novel techniques, called optical genome mapping and long-read sequencing, to sequence and analyze the genes. They sequenced 98 modern-day samples and 68 ancient DNA samples, including one from a Siberian person who lived 45,000 years ago.

The ancient DNA data in the study allowed the researchers to track how the number of amylase genes changed over time, said George Perry, PhD, an anthropological geneticist at The Pennsylvania State University-University Park (he was not involved in the study).

Based on the sequencing, the team analyzed changes in the genes in their samples to gauge evolutionary timelines. Perry noted that this was a “very clever approach to estimating the amylase copy number mutation rate, which in turn can really help in testing evolutionary hypotheses.”

The researchers found that even before farming, hunter-gatherers had between four and eight AMY1 genes in their cells. This suggests that people across Eurasia already had a number of these genes long before they started growing crops. (Recent research indicates that Neanderthals also ate starchy foods.)

“Even archaic hominins had these [genetic] variations and that indicates that they were consuming starch,” said Feyza Yilmaz, PhD, an associate computational scientist at The Jackson Laboratory in Bar Harbor, Maine, and a lead author of the study.

However, 4000 years ago, after the agricultural revolution, the research indicates that there were even more AMY1 copies acquired. Yilmaz noted, “with the advance of agriculture, we see an increase in high amylase copy number haplotypes. So genetic variation goes hand in hand with adaptation to the environment.” 

A previous study showed that species that share an environment with humans, such as dogs and pigs, also have copy number variation of amylase genes, said Yilmaz, indicating a link between genome changes and an increase in starch consumption.
 

Potential Health Impacts on Modern Humans

The duplications in the AMY1 gene could have allowed humans to better digest starches. And it’s conceivable that having more copies of the gene means being able to break down starches even more efficiently, and those with more copies “may be more prone to having high blood sugar, prediabetes, that sort of thing,” Jorgensen said.

Whether those with more AMY1 genes have more health risks is an active area of research. “Researchers tested whether there’s a correlation between AMY1 gene copies and diabetes or BMI [body mass index]. And so far, some studies show that there is indeed correlation, but other studies show that there is no correlation at all,” said Yilmaz.

Yilmaz pointed out that only 5 or 10% of carb digestion happens in our mouths, the rest occurs in our small intestine, plus there are many other factors involved in eating and metabolism.

“I am really looking forward to seeing studies which truly figure out the connection between AMY1 copy number and metabolic health and also what type of factors play a role in metabolic health,” said Yilmaz.

It’s also possible that having more AMY1 copies could lead to more carb cravings as the enzyme creates a type of sugar in our mouths. “Previous studies show that there’s a correlation between AMY1 copy number and also the amylase enzyme levels, so the faster we process the starch, the taste [of starches] will be sweeter,” said Yilmaz.

However, the link between cravings and copy numbers isn’t clear. And we don’t exactly know what came first — did the starch in humans’ diet lead to more copies of amylase genes, or did the copies of the amylase genes drive cravings that lead us to cultivate more carbs? We’ll need more research to find out.
 

How Will Today’s Processed Carbs Affect Our Genes Tomorrow?

As our diet changes to increasingly include processed carbs, what will happen to our AMY1 genes is fuzzy. “I don’t know what this could do to our genomes in the next 1000 years or more than 1000 years,” Yilmaz noted, but she said from the evidence it seems as though we may have peaked in AMY1 copies.

Jorgensen noted that this research is focused on a European population. She wonders whether the pattern of AMY1 duplication will be repeated in other populations “because the rise of starch happened first in the Middle East and then Europe and then later in the Americas,” she said.

“There’s individual variation and then there’s population-wide variation,” Jorgensen pointed out. She speculates that the historical diet of different cultures could explain population-based variations in AMY1 genes — it’s something future research could investigate. Other populations may also experience genetic changes as much of the world shifts to a more carb-heavy Western diet.

Overall, this research adds to the growing evidence that humans have a long history of loving carbs — for better and, at least over our most recent history and immediate future, for worse.

Yilmaz noted, “with the advance of agriculture, we see an increase in high amylase copy number haplotypes. So genetic variation goes hand in hand with adaptation to the environment.” 

A previous study showed that species that share an environment with humans, such as dogs and pigs, also have copy number variation of amylase genes, said Yilmaz, indicating a link between genome changes and an increase in starch consumption.
 

Potential Health Impacts on Modern Humans

The duplications in the AMY1 gene could have allowed humans to better digest starches. And it’s conceivable that having more copies of the gene means being able to break down starches even more efficiently, and those with more copies “may be more prone to having high blood sugar, prediabetes, that sort of thing,” Jorgensen said.

Whether those with more AMY1 genes have more health risks is an active area of research. “Researchers tested whether there’s a correlation between AMY1 gene copies and diabetes or BMI [body mass index]. And so far, some studies show that there is indeed correlation, but other studies show that there is no correlation at all,” said Yilmaz.

Yilmaz pointed out that only 5 or 10% of carb digestion happens in our mouths, the rest occurs in our small intestine, plus there are many other factors involved in eating and metabolism.

“I am really looking forward to seeing studies which truly figure out the connection between AMY1 copy number and metabolic health and also what type of factors play a role in metabolic health,” said Yilmaz.

It’s also possible that having more AMY1 copies could lead to more carb cravings as the enzyme creates a type of sugar in our mouths. “Previous studies show that there’s a correlation between AMY1 copy number and also the amylase enzyme levels, so the faster we process the starch, the taste [of starches] will be sweeter,” said Yilmaz.

However, the link between cravings and copy numbers isn’t clear. And we don’t exactly know what came first — did the starch in humans’ diet lead to more copies of amylase genes, or did the copies of the amylase genes drive cravings that lead us to cultivate more carbs? We’ll need more research to find out.
 

How Will Today’s Processed Carbs Affect Our Genes Tomorrow?

As our diet changes to increasingly include processed carbs, what will happen to our AMY1 genes is fuzzy. “I don’t know what this could do to our genomes in the next 1000 years or more than 1000 years,” Yilmaz noted, but she said from the evidence it seems as though we may have peaked in AMY1 copies.

Jorgensen noted that this research is focused on a European population. She wonders whether the pattern of AMY1 duplication will be repeated in other populations “because the rise of starch happened first in the Middle East and then Europe and then later in the Americas,” she said.

“There’s individual variation and then there’s population-wide variation,” Jorgensen pointed out. She speculates that the historical diet of different cultures could explain population-based variations in AMY1 genes — it’s something future research could investigate. Other populations may also experience genetic changes as much of the world shifts to a more carb-heavy Western diet.

Overall, this research adds to the growing evidence that humans have a long history of loving carbs — for better and, at least over our most recent history and immediate future, for worse.

Trying to reduce your carbohydrate intake means going against nearly a million years of evolution.

Humans are among a few species with multiple copies of certain genes that help us break down starch — carbs like potatoes, beans, corn, and grains — so that we can turn it into energy our bodies can use.

However, it’s been difficult for researchers to pinpoint when in human history we acquired multiple copies of these genes because they’re in a region of the genome that’s hard to sequence.

A recent study published in Science suggests that humans may have developed multiple copies of the gene for amylase — an enzyme that’s the first step in starch digestion — over 800,000 years ago, long before the agricultural revolution. This genetic change could have helped us adapt to eating starchy foods.

The study shows how “what your ancestors ate thousands of years ago could be affecting our genetics today,” said Kelsey Jorgensen, PhD, a biological anthropologist at The University of Kansas, Lawrence, who was not involved in the study.

The double-edged sword has sharpened over all those centuries. On one hand, the human body needs and craves carbs to function. On the other hand, our modern-day consumption of carbs, especially calorie-dense/nutritionally-barren processed carbs, has long since passed “healthy.”
 

How Researchers Found Our Carb-Lover Gene

The enzyme amylase turns complex carbs into maltose, a sweet-tasting sugar that is made of two glucose molecules linked together. We make two kinds of amylases: Salivary amylase that breaks down carbs in our mouths and pancreatic amylase that is secreted into our small intestines.

Modern humans have multiple copies of both amylases. Past research showed that human populations with diets high in starch can have up to nine copies of the gene for salivary amylase, called AMY1.

To pinpoint when in human history we acquired multiple copies of AMY1, the new study utilized novel techniques, called optical genome mapping and long-read sequencing, to sequence and analyze the genes. They sequenced 98 modern-day samples and 68 ancient DNA samples, including one from a Siberian person who lived 45,000 years ago.

The ancient DNA data in the study allowed the researchers to track how the number of amylase genes changed over time, said George Perry, PhD, an anthropological geneticist at The Pennsylvania State University-University Park (he was not involved in the study).

Based on the sequencing, the team analyzed changes in the genes in their samples to gauge evolutionary timelines. Perry noted that this was a “very clever approach to estimating the amylase copy number mutation rate, which in turn can really help in testing evolutionary hypotheses.”

The researchers found that even before farming, hunter-gatherers had between four and eight AMY1 genes in their cells. This suggests that people across Eurasia already had a number of these genes long before they started growing crops. (Recent research indicates that Neanderthals also ate starchy foods.)

“Even archaic hominins had these [genetic] variations and that indicates that they were consuming starch,” said Feyza Yilmaz, PhD, an associate computational scientist at The Jackson Laboratory in Bar Harbor, Maine, and a lead author of the study.

However, 4000 years ago, after the agricultural revolution, the research indicates that there were even more AMY1 copies acquired.

TOPLINE:

Stroke rates in Californians with sickle cell disease (SCD) have increased in both children and adults in the post-STOP era. The cumulative incidence of first ischemic stroke was 2.1% by age 20 and 13.5% by age 60.

METHODOLOGY:

• Researchers analyzed data from the California Department of Health Care Access and Innovation (HCAI), covering emergency department and hospitalization records from 1991 to 2019.
• A total of 7636 patients with SCD were included in the study cohort.
• Cumulative incidence and rates for primary and recurrent strokes and transient ischemic attacks (TIAs) were determined pre- and post STOP trial.
• Patients with SCD were identified using ICD-9 and ICD-10 codes, with specific criteria for inclusion based on hospitalization records.
• The study utilized Fine and Gray methodology to calculate cumulative incidence functions, accounting for the competing risk for death.

TAKEAWAY:

• The cumulative incidence of first ischemic stroke in patients with SCD was 2.1% by age 20 and 13.5% by age 60.
• Ischemic stroke rates increased significantly in children and adults in the 2010-2019 period, compared with the preceding decade.
• Risk factors for stroke and TIA included increasing age, hypertension, and hyperlipidemia.
• The study found a significant increase in rates of intracranial hemorrhage in adults aged 18-30 years and TIAs in children younger than 18 years from 2010 to 2019, compared with the prior decade.

IN PRACTICE:

“Neurovascular complications, including strokes and transient ischemic attacks (TIAs), are common and cause significant morbidity in individuals with sickle cell disease (SCD). The STOP trial (1998) established chronic transfusions as the standard of care for children with SCD at high risk for stroke,” the study’s authors wrote.

SOURCE:

This study was led by Olubusola B. Oluwole, MD, MS, University of Pittsburgh in Pennsylvania, and was published online in Blood.

LIMITATIONS:

This study’s reliance on administrative data may have introduced systematic errors, particularly with the transition from ICD-9 to ICD-10 codes. The lack of laboratory results and medication data in the HCAI database limited the ability to fully assess patient conditions and treatments. Additionally, the methodology changes in 2014 likely underreported death rates in people without PDD/EDU encounters in the calendar year preceding their death.

DISCLOSURES:

The authors reported no relevant conflicts of interest.

The sun often is rising in the rearview mirror as I travel with the University of New Mexico dermatology team from Albuquerque to our satellite clinic in Gallup, New Mexico. This twice-monthly trip—with a group usually comprising an attending physician, residents, and medical students—provides an invaluable opportunity for me to take part in delivering care to a majority Native American population and connects our institution and its trainees to the state’s rural and indigenous cultures and communities.

Community outreach is an important initiative for many dermatology residency training programs. Engaging with the community outside the clinic setting allows residents to hone their clinical skills, interact with and meet new people, and help to improve access to health care, especially for members of underserved populations.

Limited access to health care remains a pressing issue in the United States, especially for underserved and rural communities. There currently is no standardized way to measure access to care, but multiple contributing factors have been identified, including but not limited to patient wait times and throughput, provider turnover, ratio of dermatologists to patient population, insurance type, and patient outcomes.¹ Fortunately, there are many ways for dermatology residents to get involved and improve access to dermatologic services in their communities, including skin cancer screenings, free clinics, and teledermatology.

Skin Cancer Screenings

More than 40% of community outreach initiatives offered by dermatology residency programs are related to skin cancer screening and prevention.² The American Academy of Dermatology’s free skin cancer check program (https://www.aad.org/member/career/volunteer/spot) offers a way to participate in or even host a skin cancer screening in your community. Since 1985, this program has identified nearly 300,000 suspicious lesions and more than 30,000 suspected melanomas. Resources for setting up a skin cancer screening in your community are available on the program’s website. Residents may take this opportunity to teach medical students how to perform full-body skin examinations and/or practice making independent decisions as the supervisor for medical trainees. Skin cancer screening events not only expand access to care in underserved communities but also help residents feel more connected to the local community, especially if they have moved to a new location for their residency training.

Free Clinics

Engaging in educational opportunities offered through residency programs is another way to participate in community outreach. In particular, many programs are affiliated with a School of Medicine within their institution that allows residents to spearhead volunteer opportunities such as working at a free clinic. In fact, more than 30% of initiatives offered at dermatology residency programs are free general dermatology clinics.² Residents are in the unique position of being both learners themselves as well as educators to trainees.³ As part of our role, we can provide crucial specialty care to the community by working in concert with medical students and while also familiarizing ourselves with treating populations that we may not reach in our daily clinical work. For example, by participating in free clinics, we can provide care to vulnerable populations who typically may have financial or time barriers that prevent them from seeking care at the institution-associated clinic, including individuals experiencing homelessness, patients who are uninsured, and individuals who cannot take time off work to pursue medical care. Our presence in the community helps to reduce barriers to specialty care, particularly in the field of dermatology where the access shortage in the context of rising skin cancer rates prompts public health concerns.⁴

Teledermatology

Teledermatology became a way to extend our reach in the community more than ever before during the COVID-19 pandemic. Advances in audio, visual, and data telecommunication have been particularly helpful in dermatology, a specialty that relies heavily on visual cues for diagnosis. Synchronous, asynchronous, and hybrid teledermatology services implemented during the pandemic have gained favor among patients and dermatologists and are still applied in current practice.^5,6

For example, in the state of New Mexico (where there is a severe shortage of board-certified dermatologists to care for the state’s population), teledermatology has allowed rural providers of all specialties to consult University of New Mexico dermatologists by sending clinical photographs along with patient information and history via secure messaging. Instead of having the patient travel hundreds of miles to see the nearest dermatologist for their skin condition or endure long wait times to get in to see a specialist, primary providers now can initiate treatment or work-up for their patient’s skin issue in a timely manner with the use of teledermatology to consult specialists.

Teledermatology has demonstrated cost-effectiveness, accuracy, and efficiency in conveniently expanding access to care. It offers patients and dermatologists flexibility in receiving and delivering health care, respectively.⁷ As residents, learning how to navigate this technologic frontier in health care delivery is imperative, as it will remain a prevalent tool in the future care of our communities, particularly in underserved areas.

Final Thoughts

Through community outreach initiatives, dermatology residents have an opportunity not only to enrich our education but also to connect with and become closer to our patients. Skin cancer screenings, free clinics, and teledermatology have provided ways to reach more communities and remain important aspects of dermatology residency.

ABU DHABI, UAE — The long-standing debate as to when to start anticoagulation in patients with an acute ischemic stroke and atrial fibrillation (AF) looks as though it’s settled.

Results of the OPTIMAS trial, the largest trial to address this question, showed that initiation of a direct oral anticoagulant (DOAC) within 4 days after ischemic stroke associated with AF was noninferior to delayed initiation (7-14 days) for the composite outcome of ischemic stroke, intracranial hemorrhage, unclassifiable stroke, or systemic embolism at 90 days. Importantly, early DOAC initiation was safe with a low rate of symptomatic hemorrhage, regardless of stroke severity.

In addition, a new meta-analysis, known as CATALYST, which included all four randomized trials now available on this issue, showed a clear benefit of earlier initiation (within 4 days) versus later (5 days and up) on its primary endpoint of new ischemic stroke, symptomatic intracerebral hemorrhage, and unclassified stroke at 30 days.

The results of the OPTIMAS trial and the meta-analysis were both presented at the 16th World Stroke Congress (WSC) 2024. The OPTIMAS trial was also simultaneously published online in The Lancet.

“Our findings do not support the guideline recommended practice of delaying DOAC initiation after ischemic stroke with AF regardless of clinical stroke severity, reperfusion or prior anticoagulation,” said OPTIMAS investigator David Werring, PhD, University College London in England.

Presenting the meta-analysis, Signild Åsberg, MD, Uppsala University, Uppsala, Sweden, said his group’s findings “support the early start of DOACs (within 4 days) in clinical practice.”

Werring pointed out that starting anticoagulation early also had important logistical advantages.

“This means we can start anticoagulation before patients are discharged from hospital, thus ensuring that this important secondary prevention medication is always prescribed, when appropriate. That’s going to be a key benefit in the real world.”
 

Clinical Dilemma

Werring noted that AF accounts for 20%-30% of ischemic strokes, which tend to be more severe than other stroke types. The pivotal trials of DOACs did not include patients within 30 days of an acute ischemic stroke, creating a clinical dilemma on when to start this treatment.

“On the one hand, we wish to start anticoagulation early to reduce early recurrence of ischemic stroke. But on the other hand, there are concerns that if we start anticoagulation early, it could cause intracranial bleeding, including hemorrhagic transformation of the acute infarct. Guidelines on this issue are inconsistent and have called for randomized control trials in this area,” he noted.

So far, three randomized trials on DOAC timing have been conducted, which Werring said suggested early DOAC treatment is safe. However, these trials have provided limited data on moderate to severe stroke, patients with hemorrhagic transformation, or those already taking oral anticoagulants — subgroups in which there are particular concerns about early oral anticoagulation.

The OPTIMAS trial included a broad population of patients with acute ischemic stroke associated with AF including these critical subgroups.

The trial, conducted at 100 hospitals in the United Kingdom, included 3648 patients with AF and acute ischemic stroke who were randomly assigned to early (≤ 4 days from stroke symptom onset) or delayed (7-14 days) anticoagulation initiation with any DOAC.

There was no restriction on stroke severity, and patients with hemorrhagic transformation were allowed, with the exception of parenchymal hematoma type 2, a rare and severe type of hemorrhagic transformation.

Approximately 35% of patients had been taking an oral anticoagulant, mainly DOACs, prior to their stroke, and about 30% had revascularization with thrombolysis, thrombectomy, or both. Nearly 900 participants (25%) had moderate to severe stroke (National Institutes of Health Stroke Scale [NIHSS] score ≥ 11).

The primary outcome was a composite of recurrent ischemic stroke, symptomatic intracranial hemorrhage, unclassifiable stroke, or systemic embolism incidence at 90 days. The initial analysis aimed to show noninferiority of early DOAC initiation, with a noninferiority margin of 2 percentage points, followed by testing for superiority.

Results showed that the primary outcome occurred in 3.3% of both groups (adjusted risk difference, 0.000; 95% CI, −0.011 to 0.012), with noninferiority criteria fulfilled. Superiority was not achieved.

Symptomatic intracranial hemorrhage occurred in 0.6% of patients in the early DOAC initiation group vs 0.7% of those in the delayed group — a nonsignificant difference.
 

Applicable to Real-World Practice

A time-to-event analysis of the primary outcome showed that there were fewer outcomes in the first 30 days in the early DOAC initiation group, but the curves subsequently came together.

Subgroup analysis showed consistent results across all whole trial population, with no modification of the effect of early DOAC initiation according to stroke severity, reperfusion treatment, or previous anticoagulation.

Werring said that strengths of the OPTIMAS trial included a large sample size, a broad population with generalizability to real-world practice, and the inclusion of patients at higher bleeding risk than included in previous studies.

During the discussion, it was noted that the trial included few (about 3%) patients — about 3% — with very severe stroke (NIHSS score > 21), with the question of whether the findings could be applied to this group.

Werring noted that there was no evidence of heterogeneity, and if anything, patients with more severe strokes may have had a slightly greater benefit with early DOAC initiation. “So my feeling is probably these results do generalize to the more severe patients,” he said.

In a commentary accompanying The Lancet publication of the OPTIMAS trial, Else Charlotte Sandset, MD, University of Oslo, in Norway, and Diana Aguiar de Sousa, MD, Central Lisbon University Hospital Centre, Lisbon, Portugal, noted that the “increasing body of evidence strongly supports the message that initiating anticoagulation early for patients with ischaemic stroke is safe. The consistent absence of heterogeneity in safety outcomes suggests that the risk of symptomatic intracranial haemorrhage is not a major concern, even in patients with large infarcts.”

Regardless of the size of the treatment effect, initiating early anticoagulation makes sense when it can be done safely, as it helps prevent recurrent ischemic strokes and other embolic events. Early intervention reduces embolization risk, particularly in high-risk patients, and allows secondary prevention measures to begin while patients are still hospitalized, they added.
 

CATALYST Findings

The CATALYST meta-analysis included four trials, namely, TIMING, ELAN, OPTIMAS, and START, of early versus later DOAC administration in a total of 5411 patients with acute ischemic stroke and AF. In this meta-analysis, early was defined as within 4 days of stroke and later as 5 days or more.

The primary outcome was a composite of ischemic stroke, symptomatic, intracerebral hemorrhage, or unclassified stroke at 30 days. This was significantly reduced in the early group (2.12%) versus 3.02% in the later group, giving an odds ratio of 0.70 (95% CI, 0.50-0.98; P =.04).

The results were consistent across all subgroups, all suggesting an advantage for early DOAC.

Further analysis showed a clear benefit of early DOAC initiation in ischemic stroke with the curves separating early.

The rate of symptomatic intracerebral hemorrhage was low in both groups (0.45% in the early group and 0.40% in the later group) as was extracranial hemorrhage (0.45% vs 0.55%).

At 90 days, there were still lower event rates in the early group than the later one, but the difference was no longer statistically significant.
 

‘Practice Changing’ Results

Commenting on both studies, chair of the WSC session where the results of both OPTIMAS trial and the meta-analysis were presented, Craig Anderson, MD, The George Institute for Global Health, Sydney, Australia, described these latest results as “practice changing.”

“When to start anticoagulation in acute ischemic stroke patients with AF has been uncertain for a long time. The dogma has always been that we should wait. Over the years, we’ve become a little bit more confident, but now we’ve got good data from randomized trials showing that early initiation is safe, with the meta-analysis showing benefit,” he said.

“These new data from OPTIMAS will reassure clinicians that there’s no excessive harm and, more importantly, no excessive harm across all patient groups. And the meta-analysis clearly showed an upfront benefit of starting anticoagulation early. That’s a very convincing result,” he added.

Anderson cautioned that there still may be concerns about starting DOACs early in some groups, including Asian populations that have a higher bleeding risk (these trials included predominantly White patients) and people who are older or frail, who may have extensive small vessel disease.

During the discussion, several questions centered on the lack of imaging data available on the patients in the studies. Anderson said imaging data would help reassure clinicians on the safety of early anticoagulation in patients with large infarcts.

“Stroke clinicians make decisions on the basis of the patient and on the basis of the brain, and we only have the patient information at the moment. We don’t have information on the brain — that comes from imaging.”

Regardless, he believes these new data will lead to a shift in practice. “But maybe, it won’t be as dramatic as we would hope because I think some clinicians may still hesitate to apply these results to patients at high risk of bleeding. With imaging data from the studies that might change.”

The OPTIMAS trial was funded by University College London and the British Heart Foundation. Werring reported consulting fees from Novo Nordisk, National Institute for Health and Care Excellence, and Alnylam; payments or speaker honoraria from Novo Nordisk, Bayer, and AstraZeneca/Alexion; participation on a data safety monitoring board for the OXHARP trial; and participation as steering committee chair for the MACE-ICH and PLINTH trials. Åsberg received institutional research grants and lecture fees to her institution from AstraZeneca, Boehringer Ingelheim, Bristol Myers Squibb, and Institut Produits Synthése. Sandset and de Sousa were both steering committee members of the ELAN trial. Anderson reported grant funding from Penumbra and Takeda China.

ABU DHABI, UAE — The long-standing debate as to when to start anticoagulation in patients with an acute ischemic stroke and atrial fibrillation (AF) looks as though it’s settled.

Results of the OPTIMAS trial, the largest trial to address this question, showed that initiation of a direct oral anticoagulant (DOAC) within 4 days after ischemic stroke associated with AF was noninferior to delayed initiation (7-14 days) for the composite outcome of ischemic stroke, intracranial hemorrhage, unclassifiable stroke, or systemic embolism at 90 days. Importantly, early DOAC initiation was safe with a low rate of symptomatic hemorrhage, regardless of stroke severity.

In addition, a new meta-analysis, known as CATALYST, which included all four randomized trials now available on this issue, showed a clear benefit of earlier initiation (within 4 days) versus later (5 days and up) on its primary endpoint of new ischemic stroke, symptomatic intracerebral hemorrhage, and unclassified stroke at 30 days.

The results of the OPTIMAS trial and the meta-analysis were both presented at the 16th World Stroke Congress (WSC) 2024. The OPTIMAS trial was also simultaneously published online in The Lancet.

“Our findings do not support the guideline recommended practice of delaying DOAC initiation after ischemic stroke with AF regardless of clinical stroke severity, reperfusion or prior anticoagulation,” said OPTIMAS investigator David Werring, PhD, University College London in England.

Presenting the meta-analysis, Signild Åsberg, MD, Uppsala University, Uppsala, Sweden, said his group’s findings “support the early start of DOACs (within 4 days) in clinical practice.”

Werring pointed out that starting anticoagulation early also had important logistical advantages.

“This means we can start anticoagulation before patients are discharged from hospital, thus ensuring that this important secondary prevention medication is always prescribed, when appropriate. That’s going to be a key benefit in the real world.”
 

Clinical Dilemma

Werring noted that AF accounts for 20%-30% of ischemic strokes, which tend to be more severe than other stroke types. The pivotal trials of DOACs did not include patients within 30 days of an acute ischemic stroke, creating a clinical dilemma on when to start this treatment.

“On the one hand, we wish to start anticoagulation early to reduce early recurrence of ischemic stroke. But on the other hand, there are concerns that if we start anticoagulation early, it could cause intracranial bleeding, including hemorrhagic transformation of the acute infarct. Guidelines on this issue are inconsistent and have called for randomized control trials in this area,” he noted.

THE DIAGNOSIS: Chemotherapy-Induced Flagellate Dermatitis

Based on the clinical presentation and temporal relation with chemotherapy, a diagnosis of bleomycininduced flagellate dermatitis (FD) was made, as bleomycin is the only chemotherapeutic agent from this regimen that has been linked with FD.^1,2 Laboratory findings revealed eosinophilia, further supporting a druginduced dermatitis. The patient was treated with oral steroids and diphenhydramine to alleviate itching and discomfort. The chemotherapy was temporarily discontinued until symptomatic improvement was observed within 2 to 3 days.

Flagellate dermatitis is characterized by unique erythematous, linear, intermingled streaks of adjoining firm papules—often preceded by a prodrome of global pruritus—that eventually become hyperpigmented as the erythema subsides. The clinical manifestation of FD can be idiopathic; true/mechanical (dermatitis artefacta, abuse, sadomasochism); chemotherapy induced (peplomycin, trastuzumab, cisplatin, docetaxel, bendamustine); toxin induced (shiitake mushroom, cnidarian stings, Paederus insects); related to rheumatologic diseases (dermatomyositis, adult-onset Still disease), dermatographism, phytophotodermatitis, or poison ivy dermatitis; or induced by chikungunya fever.¹

The term flagellate originates from the Latin word flagellum, which pertains to the distinctive whiplike pattern. It was first described by Moulin et al³ in 1970 in reference to bleomycin-induced linear hyperpigmentation. Bleomycin, a glycopeptide antibiotic derived from Streptomyces verticillus, is used to treat Hodgkin lymphoma, squamous cell carcinoma, and germ cell tumors. The worldwide incidence of bleomycin-induced FD is 8% to 22% and commonly is associated with a cumulative dose greater than 100 U.² Clinical presentation is variable in terms of onset, distribution, and morphology of the eruption and could be independent of dose, route of administration, or type of malignancy being treated. The flagellate rash commonly involves the trunk, arms, and legs; can develop within hours to 6 months of starting bleomycin therapy; often is preceded by generalized itching; and eventually heals with hyperpigmentation.

Possible mechanisms of bleomycin-induced FD include localized melanogenesis, inflammatory pigmentary incontinence, alterations to normal pigmentation patterns, cytotoxic effects of the drug itself, minor trauma/ scratching leading to increased blood flow and causing local accumulation of bleomycin, heat recall, and reduced epidermal turnover leading to extended interaction between keratinocytes and melanocytes.² Heat exposure can act as a trigger for bleomycin-induced skin rash recall even months after the treatment is stopped.

Apart from discontinuing the drug, there is no specific treatment available for bleomycin-induced FD. The primary objective of treatment is to alleviate pruritus, which often involves the use of topical or systemic corticosteroids and oral antihistamines. The duration of treatment depends on the patient’s clinical response. Once treatment is discontinued, FD typically resolves within 6 to 8 months. However, there can be a permanent postinflammatory hyperpigmentation in the affected area.⁴ Although there is a concern for increased mortality after postponement of chemotherapy,⁵ the decision to proceed with or discontinue the chemotherapy regimen necessitates a comprehensive interdisciplinary discussion and a meticulous assessment of the risks and benefits that is customized to each individual patient. Flagellate dermatitis can reoccur with bleomycin re-exposure; a combined approach of proactive topical and systemic steroid treatment seems to diminish the likelihood of FD recurrence.⁵

Our case underscores the importance of recognizing, detecting, and managing FD promptly in individuals undergoing bleomycin-based chemotherapy. Medical professionals should familiarize themselves with this distinct adverse effect linked to bleomycin, enabling prompt discontinuation if necessary, and educate patients about the condition’s typically temporary nature, thereby alleviating their concerns.

Based on the clinical presentation and temporal relation with chemotherapy, a diagnosis of bleomycininduced flagellate dermatitis (FD) was made, as bleomycin is the only chemotherapeutic agent from this regimen that has been linked with FD.^1,2 Laboratory findings revealed eosinophilia, further supporting a druginduced dermatitis. The patient was treated with oral steroids and diphenhydramine to alleviate itching and discomfort. The chemotherapy was temporarily discontinued until symptomatic improvement was observed within 2 to 3 days.

Flagellate dermatitis is characterized by unique erythematous, linear, intermingled streaks of adjoining firm papules—often preceded by a prodrome of global pruritus—that eventually become hyperpigmented as the erythema subsides. The clinical manifestation of FD can be idiopathic; true/mechanical (dermatitis artefacta, abuse, sadomasochism); chemotherapy induced (peplomycin, trastuzumab, cisplatin, docetaxel, bendamustine); toxin induced (shiitake mushroom, cnidarian stings, Paederus insects); related to rheumatologic diseases (dermatomyositis, adult-onset Still disease), dermatographism, phytophotodermatitis, or poison ivy dermatitis; or induced by chikungunya fever.¹

The term flagellate originates from the Latin word flagellum, which pertains to the distinctive whiplike pattern. It was first described by Moulin et al³ in 1970 in reference to bleomycin-induced linear hyperpigmentation. Bleomycin, a glycopeptide antibiotic derived from Streptomyces verticillus, is used to treat Hodgkin lymphoma, squamous cell carcinoma, and germ cell tumors. The worldwide incidence of bleomycin-induced FD is 8% to 22% and commonly is associated with a cumulative dose greater than 100 U.² Clinical presentation is variable in terms of onset, distribution, and morphology of the eruption and could be independent of dose, route of administration, or type of malignancy being treated. The flagellate rash commonly involves the trunk, arms, and legs; can develop within hours to 6 months of starting bleomycin therapy; often is preceded by generalized itching; and eventually heals with hyperpigmentation.

Possible mechanisms of bleomycin-induced FD include localized melanogenesis, inflammatory pigmentary incontinence, alterations to normal pigmentation patterns, cytotoxic effects of the drug itself, minor trauma/ scratching leading to increased blood flow and causing local accumulation of bleomycin, heat recall, and reduced epidermal turnover leading to extended interaction between keratinocytes and melanocytes.² Heat exposure can act as a trigger for bleomycin-induced skin rash recall even months after the treatment is stopped.

Apart from discontinuing the drug, there is no specific treatment available for bleomycin-induced FD. The primary objective of treatment is to alleviate pruritus, which often involves the use of topical or systemic corticosteroids and oral antihistamines. The duration of treatment depends on the patient’s clinical response. Once treatment is discontinued, FD typically resolves within 6 to 8 months. However, there can be a permanent postinflammatory hyperpigmentation in the affected area.⁴ Although there is a concern for increased mortality after postponement of chemotherapy,⁵ the decision to proceed with or discontinue the chemotherapy regimen necessitates a comprehensive interdisciplinary discussion and a meticulous assessment of the risks and benefits that is customized to each individual patient. Flagellate dermatitis can reoccur with bleomycin re-exposure; a combined approach of proactive topical and systemic steroid treatment seems to diminish the likelihood of FD recurrence.⁵

Our case underscores the importance of recognizing, detecting, and managing FD promptly in individuals undergoing bleomycin-based chemotherapy. Medical professionals should familiarize themselves with this distinct adverse effect linked to bleomycin, enabling prompt discontinuation if necessary, and educate patients about the condition’s typically temporary nature, thereby alleviating their concerns.

As a physician, you might be contacted by the media to provide your professional opinion and advice. Or you might be looking for media interview opportunities to market your practice or side project. And if you do research, media interviews can be an effective way to spread the word. It’s important to prepare for a media interview so that you achieve the outcome you are looking for. Here are six tips I learned from writing health articles, interviewing experts, and being interviewed myself. 

Keep your message simple. When you are a subject expert, you might think that the basics are obvious or even boring, and that the nuances are more important. However, most of the audience is looking for big-picture information that they can apply to their lives. Consider a few key takeaways, keeping in mind that your interview is likely to be edited to short sound bites or a few quotes. It may help to jot down notes so that you cover the fundamentals clearly. You could even write and rehearse a script beforehand. If there is something complicated or subtle that you want to convey, you can preface it by saying, “This is confusing but very important …” to let the audience know to give extra consideration to what you are about to say.

Avoid extremes and hyperbole. Sometimes, exaggerated statements make their way into medical discussions. Statements such as “it doesn’t matter how many calories you consume — it’s all about the quality” are common oversimplifications. But you might be upset to see your name next to a comment like this because it is not actually correct. Check the phrasing of your key takeaways to avoid being stuck defending or explaining an inaccurate statement when your patients ask you about it later. 

Ask the interviewers what they are looking for. Many medical topics have some controversial element, so it is good to know what you’re getting into. Find out the purpose of the article or interview before you decide whether it is right for you. It could be about another doctor in town who is being sued; if you don’t want to be associated with that story, it might be best to decline the interview. 

Explain your goals. You might accept or pursue an interview to raise awareness about an underrecognized condition. You might want the public to identify and get help for early symptoms, or you might want to create empathy for people coping with a disease you treat. Consider why you are participating in an interview, and communicate that to the interviewer to ensure that your objective can be part of the final product. 

Know whom you’re dealing with. It is good to learn about the publication/media channel before you agree to participate. It may have a political bias, or perhaps the interview is intended to promote a specific product. If you agree with and support their purposes, then you may be happy to lend your opinion. But learning about the “voice” of the publication in advance allows you to make an informed decision about whether you want to be identified with a particular political ideology or product endorsement.

Ask to see your quotes before publication. It’s good to have the opportunity to make corrections in case you are accidentally misquoted or misunderstood. It is best to ask to see quotes before you agree to the interview. Some reporters may agree to (or even prefer) a written question-and-answer format so that they can directly quote your responses without rephrasing your words. You could suggest this, especially if you are too busy for a call or live meeting.

As a physician, your insights and advice can be highly beneficial to others. You can also use media interviews to propel your career forward. Doing your homework can ensure that you will be pleased with the final product and how your words were used.

The incidence of lung cancer in never-smokers (LCINS) is increasing, and experts think climate change may be driving the uptick.

LCINS differs histologically and epidemiologically from smoking-related cancers, occurring almost always as adenocarcinomas and mostly affecting women and individuals of Asian ancestry, according to a study published in Nature Reviews Clinical Oncology in January 2024. Cases of LCINS are estimated to be the fifth most common cause of cancer-related deaths worldwide.

During a plenary session at the 2024 World Congress on Lung Cancer, experts addressed the known and suspected causes of LCINS, including fallout from climate change, vaping, cannabis use, and effects of airborne carcinogen exposures arising from military conflict. These potential culprits are varied and sometimes interrelated — and they underscore the need for continued emphasis on environmental hazards, the panelists agreed.

Focusing on climate change — and taking action at the individual level — is a good place to start, said Leticia M. Nogueira, PhD, scientific director of health services research in the Surveillance and Health Equity Science Department of the American Cancer Society.
 

Long-Term Exposure to Wildfires Linked to Increased Cancer Risk

Climate change is associated with climate-driven disasters such as more intense hurricanes and more frequent wildfires that can expose populations to environmental carcinogens, Nogueira explained.

Such weather events disrupt the care of patients with cancer and lead to poorer outcomes, according to her own research. They also contribute to the rising incidence of LCINS, she said.

In a population-based study published in The Lancet Planetary Health, long-term exposure to wildfires was associated with an increased risk for lung cancer and brain tumors. Individuals exposed to a wildfire within 50 km of their residential locations in the prior decade has a 4.9% relatively higher incidence of lung cancer and a 10% relatively higher incidence of brain tumors.

“These findings are relevant on a global scale given the anticipated effects of climate change on wildfire frequency and severity,” the authors concluded, noting the study limitations and the need for further research.
 

How Clinicians Can Help

Nogueira urged attendees to take action to help improve healthcare outcomes.

“Let’s not forget that the healthcare system is one of the most emission-intensive industries in the world. Emissions from the US healthcare system exceed emission from the entire UK, and we can be doing much better.

“There is something for each one of us here today to do: We can champion environmentally responsible efforts at our institutions, we can engage with disaster preparedness and response ... and we can document ongoing suffering to increase awareness and incentivize action,” she said.

In a commentary published in CA: A Cancer Journal for Clinicians, Nogueira and her colleagues further addressed the links between climate change and cancer and listed various sources of greenhouse gas emissions and proposed interventions, including those associated with the healthcare industry.

“If you look at this list and say ‘No way — there is no chance my institution will do any of that,’ let me ask you something: Are you allowed to smoke on campus? How do you think that happened? How do you think that started?” she said, invoking Archimedes’ famous quote, “Give me a lever long enough, and I shall move the world.”

“You most certainly have the power to make a difference,” Nogueira said. “So recognize where your points of influence are – move your lever, move the world.”
