More than 140 million Americans use artificial sweeteners, a habit driven by the irrefutable fact that excess sugar is harmful. But I’m continually amazed by alarmist headlines on the topic.

In May, the World Health Organization (WHO) released a report to support its “conditional recommendation” against the use of non-sugar sweeteners (NSS) for weight control. Despite the WHO’s goal “to provide evidence-informed guidance,” the report includes the disclaimer that “The recommendation is based on evidence of low certainty.”

Low certainty is an accurate descriptor for the findings of many of the 280-plus studies in the report. That the guidance does not apply to patients with diabetes was easily lost in the repeated mentions of the perceived dangers of these sugar alternatives.

The review included various table-top and beverage sweeteners, including acesulfame K, aspartame, saccharin, sucralose, stevia, and stevia derivatives. Low-calorie sugars and sugar alcohols such as erythritol were excluded.

The WHO looked at long- and short-term trials, randomized controlled trials (RCTs), prospective studies, and case-control studies measuring a wide range of endpoints, from dental caries to cancer. The report highlighted that some findings cannot be attributed directly to NSS use but may simply be due to their substitution for sugar. Differences in outcomes due to sex, ethnicity, and body weight status could not be assessed either. And the WHO conceded the possibility of reverse causation in observational studies wherein higher-risk individuals may consume more NSS.

Nonnutritive sweeteners are given little credit for weight loss. “A significant difference in body weight and BMI was only observed in trials that reported a reduction in energy intake ... rather than primarily by an inherent property of NSS that can modulate body weight (independently of energy intake),” the report reads. But isn’t the desired effect of using an artificial sweetener instead of table sugar that you lower your calorie intake?

The WHO noted that weight loss was not sustained – a finding in nearly every weight loss trial in history and something more attributable to human nature than the sweetener one chooses.

The document outlines that meta-analyses of prospective cohort studies show that higher intakes of NSS were associated with an increased risk for type 2 diabetes and elevated fasting glucose, while meta-analyses of randomized trials suggest no significant effect on “biomarkers used in the assessment and diagnosis of diabetes and insulin resistance, including fasting glucose, fasting insulin and hemoglobin A1c.”

Similar disparities are noted with cardiovascular risk. Prospective trials suggest an increased risk for CVD, including stroke and its precursor, hypertension; but again, the RCT data found no evidence to suggest a significant effect “on biomarkers used in the assessment and diagnosis of CVDs, including blood pressure, low-density lipoprotein cholesterol and other blood lipids.”
 

Splenda and stevia under fire

Predictably, some in the nonnutritive sweetener industry are incensed.

Ted Gelov, CEO of Heartland Food Products Group, maker of Splenda, responded in a press release, “Every few years now it seems I have to come to you and clarify misleading headlines ... Suggesting that sweeteners like Splenda cannot have long-term benefits is a disservice to healthcare providers, their patients, and all consumers.”

Splenda has been on the U.S. market since 1999, and Mr. Gelov reportedly uses three to eight packets daily in his coffee and tea.

I reached out to Heartland and they sent me an eight-page document consisting of over 50 statements, summaries, and clinical trials supporting the safety of artificial sweeteners, including sucralose, an ingredient in Splenda. In 2016, Mr. Gelov rebutted claims that sucralose was linked to cancer in Swiss male mice. These “dramatized headlines are based on one flawed study by an isolated Italian research laboratory, the Ramazzini Institute,” Mr. Gelov wrote.

Another recent headline was about the DNA-damaging effects of sucralose-6-acetate (S6A) seen in an in vitro study published in the Journal of Toxicology and Environmental Health. According to the authors, commercial sucralose samples contain up to 0.67% S6A, a manufacturing impurity.

Despite many reports linking this study to Splenda, Heartland wrote that “Splenda and its ingredients were never studied or tested in this research. We, and our suppliers, rigorously and routinely test and monitor for any impurities in our products. We can confirm that S6A is not present in Splenda Brand sucralose down to the lowest detection limit possible, which is .001% sensitivity level.”

F. Perry Wilson, MD, director of Clinical and Translational Research Accelerator at Yale and a regular contributor to this news organization, took to Twitter to put this study in context: “The human exposure equivalent to sucralose would be 60 packets per day,” he pointed out. And the blood levels of S6A with normal consumption would not “come close to the DNA damage threshold noted in the article.”

Perhaps the most concerning scientific data suggesting a link between artificial sweetener use and ill health is a Cleveland Clinic study showing an association between higher blood levels of erythritol and adverse cardiovascular outcomes such as heart attack, stroke, or death. The researchers also found that erythritol, which is found in stevia and some keto food products, made platelet activation and clot formation easier.

When I asked about these findings, Heartland stated, “The study was primarily conducted on patients who were at an elevated risk of cardiovascular events due to their advanced age, elevated body mass and presence of pre-existing health conditions ... the stated findings were only an association and cannot imply causation.”

The main conclusion I’ve drawn on the topic of artificial sweeteners is that a lot of resources were wasted in performing underpowered, poorly designed trials on compounds that are already generally regarded as safe (GRAS) by the FDA. The WHO “conditional guideline” is, by its own description, based on a plethora of “low certainty” to “very low certainty” evidence.

The monies to produce the WHO report and many of these trials would have been better spent educating the public on the difference between simple and complex carbohydrates; the inflammatory and disease-producing effects of excess sugars; and how to prevent, diagnose, and treat diabetes.

If more trials on artificial sweeteners are planned, they should be performed on people doing human things – which does not include ingesting 60 packets of any sweetener in a single day.

In my personal N-of-1 trial, consuming sugar makes me crave more, feel sluggish, and gain weight. I don’t believe that NSS alone will control my weight. But I’ll continue to drink two cups of stevia-laced coffee every morning, take walks, avoid alcohol, eat my vegetables, and hope for the best.

Pediatric nephrologist Bryan Carmody, MD, recalls working alongside an extremely experienced neonatologist during his residency. She had managed a neonatal intensive care unit in her home country of Lithuania, but because she wanted to practice in the United States, it took years of repeat training before she was eligible for a medical license.

“She was very accomplished, and she was wonderful to have as a coresident at the time,” Dr. Carmody said in an interview.

The neonatologist now practices at a U.S. academic medical center, but to obtain that position, she had to complete 3 years of pediatric residency and 3 years of fellowship in the United States, Dr. Carmody said.

Such training for international medical graduates (IMGs) is a routine part of obtaining a U.S. medical license, but a new Tennessee law bypasses these requirements and creates a quicker pathway for IMGs to secure medical licenses in the United States.

The American Medical Association took similar measures at its recent annual meeting, making it easier for IMGs to gain licensure. Because the pandemic and Russia’s invasion of Ukraine disrupted the process by which some IMGs had their licenses verified, the AMA is now encouraging state licensing boards and other credentialing institutions to accept certification from the Educational Commission for Foreign Medical Graduates as verification, rather than requiring documents directly from international medical schools.

When it comes to Tennessee’s new law, signed by Gov. Bill Lee in April, experienced IMGs who have received medical training abroad can skip U.S. residency requirements and obtain a temporary license to practice medicine in Tennessee if they meet certain qualifications.

The international doctors must demonstrate competency, as determined by the state medical board. In addition, they must have completed a 3-year postgraduate training program in the graduate’s licensing country or otherwise have practiced as a medical professional in which they performed the duties of a physician for at least 3 of the past 5 years outside the United States, according to the new law.

To be approved, IMGs must also have received an employment offer from a Tennessee health care provider that has a residency program accredited by the Accreditation Council for Graduate Medical Education.

If physicians remain in good standing for 2 years, the board will grant them a full and unrestricted license to practice in Tennessee.

“The new legislation opens up a lot of doors for international medical graduates and is also a lifeline for a lot of underserved areas in Tennessee,” said Asim Ansari, MD, a Canadian who attended medical school in the Caribbean and is an advocate for IMGs.

Dr. Ansari is participating in a child and adolescent psychiatry fellowship at the University of Kansas Medical Center, Kansas City, until he can apply for the sixth time to a residency program. “This could possibly be a model that other states may want to implement in a few years.”
 

What’s behind the law?

A predicted physician shortage in Tennessee drove the legislation, said Rep. Sabi “Doc” Kumar, MD, vice chair for the Tennessee House Health Committee and a cosponsor of the legislation. Legislators hope the law will mitigate that shortage and boost the number of physicians practicing in underserved areas of the state.

“Considering that one in four physicians in the U.S. are international medical gradates, it was important for us to be able to attract those physicians to Tennessee,” he said.

The Tennessee Board of Medical Examiners will develop administrative rules for the law, which may take up to a year, Rep. Kumar said. He expects the program to be available to IMGs beginning in mid-2024.

Upon completion of the program, IMGs will be able to practice general medicine in Tennessee, not a specialty. Requirements for specialty certification would have to be met through the specialties’ respective boards.

Dr. Carmody, who blogs about medical education, including the new legislation, said in an interview the law will greatly benefit experienced IMGs, who often are bypassed as residency candidates because they graduated years ago. Hospitals also win because they can fill positions that otherwise might sit vacant, he said.

Family physician Sahil Bawa, MD, an IMG from India who recently matched into his specialty, said the Tennessee legislation will help fellow IMGs find U.S. medical jobs.

“It’s very difficult for IMGs to get into residency in the U.S.,” he said. “I’ve seen people with medical degrees from other countries drive Uber or do odd jobs to sustain themselves here. I’ve known a few people who have left and gone back to their home country because they were not accepted into a residency.”
 

Who benefits most?

Dr. Bawa noted that the legislation would not have helped him, as he needed a visa to practice in the United States and the law does not include the sponsoring of visas. The legislation requires IMGs to show evidence of citizenship or evidence that they are legally entitled to live or work in the United States.

U.S. citizen IMGs who haven’t completed residency or who practiced in another country also are left out of the law, Dr. Carmody said.

“This law is designed to take the most accomplished cream of the crop international medical graduates with the most experience and the most sophisticated skill set and send them to Tennessee. I think that’s the intent,” he said. “But many international medical graduates are U.S. citizens who don’t have the opportunity to practice in countries other than United States or do residencies. A lot of these people are sitting on the sidelines, unable to secure residency positions. I’m sure they would be desperate for a program like this.”
 

Questions remain

“Just because the doctor can get a [temporary] license without the training doesn’t mean employers are going to be interested in sponsoring those doctors,” said Adam Cohen, an immigration attorney who practices in Memphis. “What is the inclination of these employers to hire these physicians who have undergone training outside the U.S.? And will there be skepticism on the part of employers about the competence of these doctors?”

“Hospital systems will be able to hire experienced practitioners for a very low cost,” Dr. Ansari said. “So now you have these additional bodies who can do the work of a physician, but you don’t have to pay them as much as a physician for 2 years. And because some are desperate to work, they will take lower pay as long as they have a pathway to full licensure in Tennessee. What are the protections for these physicians? Who will cover their insurance? Who will be responsible for them, the attendees? And will the attendees be willing to put their license on the line for them?”

In addition, Dr. Carmody questions what, if anything, will encourage IMGs to work in underserved areas in Tennessee after their 2 years are up and whether there will be any incentives to guide them. He wonders, too, whether the physicians will be stuck practicing in Tennessee following completion of the program.

“Will these physicians only be able to work in Tennessee?” he asked. “I think that’s probably going to be the case, because they’ll be licensed in Tennessee, but to go to another state, they would be missing the required residency training. So it might be these folks are stuck in Tennessee unless other states develop reciprocal arrangements.”

Other states would have to decide whether to recognize the Tennessee license acquired through this pathway, Rep. Kumar said.

He explained that the sponsoring sites would be responsible for providing work-hour restrictions and liability protections. There are currently no incentives in the legislation for IMGs to practice in rural, underserved areas, but the hospitals and communities there generally offer incentives when recruiting, Rep. Kumar said.

“The law definitely has the potential to be helpful,” Mr. Cohen said, “because there’s an ability to place providers in the state without having to go through the bottleneck of limited residency slots. If other states see a positive effect on Tennessee or are exploring ways to alleviate their own shortages, it’s possible [they] might follow suit.”

Rep. Kumar agreed that other states will be watching Tennessee to weigh the law’s success.

“I think the law will have to prove itself and show that Tennessee has benefited from it and that the results have been good,” he said. “We are providing a pioneering way for attracting medical graduates and making it easier for them to obtain a license. I would think other states would want to do that.”

Pediatric nephrologist Bryan Carmody, MD, recalls working alongside an extremely experienced neonatologist during his residency. She had managed a neonatal intensive care unit in her home country of Lithuania, but because she wanted to practice in the United States, it took years of repeat training before she was eligible for a medical license.

“She was very accomplished, and she was wonderful to have as a coresident at the time,” Dr. Carmody said in an interview.

The neonatologist now practices at a U.S. academic medical center, but to obtain that position, she had to complete 3 years of pediatric residency and 3 years of fellowship in the United States, Dr. Carmody said.

Such training for international medical graduates (IMGs) is a routine part of obtaining a U.S. medical license, but a new Tennessee law bypasses these requirements and creates a quicker pathway for IMGs to secure medical licenses in the United States.

The American Medical Association took similar measures at its recent annual meeting, making it easier for IMGs to gain licensure. Because the pandemic and Russia’s invasion of Ukraine disrupted the process by which some IMGs had their licenses verified, the AMA is now encouraging state licensing boards and other credentialing institutions to accept certification from the Educational Commission for Foreign Medical Graduates as verification, rather than requiring documents directly from international medical schools.

When it comes to Tennessee’s new law, signed by Gov. Bill Lee in April, experienced IMGs who have received medical training abroad can skip U.S. residency requirements and obtain a temporary license to practice medicine in Tennessee if they meet certain qualifications.

The international doctors must demonstrate competency, as determined by the state medical board. In addition, they must have completed a 3-year postgraduate training program in the graduate’s licensing country or otherwise have practiced as a medical professional in which they performed the duties of a physician for at least 3 of the past 5 years outside the United States, according to the new law.

To be approved, IMGs must also have received an employment offer from a Tennessee health care provider that has a residency program accredited by the Accreditation Council for Graduate Medical Education.

If physicians remain in good standing for 2 years, the board will grant them a full and unrestricted license to practice in Tennessee.

“The new legislation opens up a lot of doors for international medical graduates and is also a lifeline for a lot of underserved areas in Tennessee,” said Asim Ansari, MD, a Canadian who attended medical school in the Caribbean and is an advocate for IMGs.

Dr. Ansari is participating in a child and adolescent psychiatry fellowship at the University of Kansas Medical Center, Kansas City, until he can apply for the sixth time to a residency program. “This could possibly be a model that other states may want to implement in a few years.”
 

What’s behind the law?

A predicted physician shortage in Tennessee drove the legislation, said Rep. Sabi “Doc” Kumar, MD, vice chair for the Tennessee House Health Committee and a cosponsor of the legislation. Legislators hope the law will mitigate that shortage and boost the number of physicians practicing in underserved areas of the state.

“Considering that one in four physicians in the U.S. are international medical gradates, it was important for us to be able to attract those physicians to Tennessee,” he said.

The Tennessee Board of Medical Examiners will develop administrative rules for the law, which may take up to a year, Rep. Kumar said. He expects the program to be available to IMGs beginning in mid-2024.

Upon completion of the program, IMGs will be able to practice general medicine in Tennessee, not a specialty. Requirements for specialty certification would have to be met through the specialties’ respective boards.

Dr. Carmody, who blogs about medical education, including the new legislation, said in an interview the law will greatly benefit experienced IMGs, who often are bypassed as residency candidates because they graduated years ago. Hospitals also win because they can fill positions that otherwise might sit vacant, he said.

Family physician Sahil Bawa, MD, an IMG from India who recently matched into his specialty, said the Tennessee legislation will help fellow IMGs find U.S. medical jobs.

“It’s very difficult for IMGs to get into residency in the U.S.,” he said. “I’ve seen people with medical degrees from other countries drive Uber or do odd jobs to sustain themselves here. I’ve known a few people who have left and gone back to their home country because they were not accepted into a residency.”
 

Who benefits most?

Dr. Bawa noted that the legislation would not have helped him, as he needed a visa to practice in the United States and the law does not include the sponsoring of visas. The legislation requires IMGs to show evidence of citizenship or evidence that they are legally entitled to live or work in the United States.

U.S. citizen IMGs who haven’t completed residency or who practiced in another country also are left out of the law, Dr. Carmody said.

“This law is designed to take the most accomplished cream of the crop international medical graduates with the most experience and the most sophisticated skill set and send them to Tennessee. I think that’s the intent,” he said. “But many international medical graduates are U.S. citizens who don’t have the opportunity to practice in countries other than United States or do residencies. A lot of these people are sitting on the sidelines, unable to secure residency positions. I’m sure they would be desperate for a program like this.”
 

Questions remain

“Just because the doctor can get a [temporary] license without the training doesn’t mean employers are going to be interested in sponsoring those doctors,” said Adam Cohen, an immigration attorney who practices in Memphis. “What is the inclination of these employers to hire these physicians who have undergone training outside the U.S.? And will there be skepticism on the part of employers about the competence of these doctors?”

“Hospital systems will be able to hire experienced practitioners for a very low cost,” Dr. Ansari said. “So now you have these additional bodies who can do the work of a physician, but you don’t have to pay them as much as a physician for 2 years. And because some are desperate to work, they will take lower pay as long as they have a pathway to full licensure in Tennessee. What are the protections for these physicians? Who will cover their insurance? Who will be responsible for them, the attendees? And will the attendees be willing to put their license on the line for them?”

In addition, Dr. Carmody questions what, if anything, will encourage IMGs to work in underserved areas in Tennessee after their 2 years are up and whether there will be any incentives to guide them. He wonders, too, whether the physicians will be stuck practicing in Tennessee following completion of the program.

“Will these physicians only be able to work in Tennessee?” he asked. “I think that’s probably going to be the case, because they’ll be licensed in Tennessee, but to go to another state, they would be missing the required residency training. So it might be these folks are stuck in Tennessee unless other states develop reciprocal arrangements.”

Other states would have to decide whether to recognize the Tennessee license acquired through this pathway, Rep. Kumar said.

He explained that the sponsoring sites would be responsible for providing work-hour restrictions and liability protections. There are currently no incentives in the legislation for IMGs to practice in rural, underserved areas, but the hospitals and communities there generally offer incentives when recruiting, Rep. Kumar said.

“The law definitely has the potential to be helpful,” Mr. Cohen said, “because there’s an ability to place providers in the state without having to go through the bottleneck of limited residency slots. If other states see a positive effect on Tennessee or are exploring ways to alleviate their own shortages, it’s possible [they] might follow suit.”

Rep. Kumar agreed that other states will be watching Tennessee to weigh the law’s success.

“I think the law will have to prove itself and show that Tennessee has benefited from it and that the results have been good,” he said. “We are providing a pioneering way for attracting medical graduates and making it easier for them to obtain a license. I would think other states would want to do that.”

PHOENIX – The way Jennifer Barton, PhD, sees it, optical coherence tomography (OCT), laser-induced fluorescence, and multiphoton microscopy are poised to revolutionize the future of cancer detection.

Chris Richards/University of Arizona

In a lecture during a multispecialty roundup of cutting-edge energy-based device applications at the annual conference of the American Society for Laser Medicine and Surgery, Dr. Barton, a biomedical engineer who directs the BIO5 Institute at the University of Arizona, Tucson, said that while no current modality exists to enable physicians in dermatology and other specialties to view internal structures throughout the entire body with cellular resolution, refining existing technologies is a good way to start.

In 2011, renowned cancer researchers Douglas Hanahan, PhD, and Robert A. Weinberg, PhD, proposed six hallmarks of cancer, which include sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis. Each hallmark poses unique imaging challenges. For example, enabling replicative immortality “means that the cell nuclei change size and shape; they change their position,” said Dr. Barton, who is also professor of biomedical engineering and optical sciences at the university. “If we want to see that, we’re going to need an imaging modality that’s subcellular in resolution.”

Similarly, if clinicians want to view how proliferative signaling is changing, “that means being able to visualize the cell surface receptors; those are even smaller to actually visualize,” she said. “But we have technologies where we can target those receptors with fluorophores. And then we can look at large areas very quickly.” Meanwhile, the ability of cancer cells to resist cell death and evade growth suppressors often results in thickening of epithelium throughout the body. “So, if we can measure the thickness of the epithelium, we can see that there’s something wrong with that tissue,” she said.

As for cancer’s propensity for invasion and metastasis, “here, we’re looking at how the collagen structure [between the cells] has changed and whether there’s layer breakdown or not. Optical imaging can detect cancer. However, high resolution optical techniques can only image about 1 mm deep, so unless you’re looking at the skin or the eye, you’re going to have to develop an endoscope to be able to view these hallmarks.”

OCT images the tissue microstructure, generally in a resolution of 2-20 microns, at a depth of 1-2 mm, and it measures reflected light. When possible, Dr. Barton combines OCT with laser-induced fluorescence for enhanced accuracy of detection of cancer. Induced fluorescence senses molecular information with the natural fluorophores in the body or with targeted exogenous agents. Then there’s multiphoton microscopy, an advanced imaging technique that enables clinicians to view cellular and subcellular events within living tissue. Early models of this technology “took up entire benches” in physics labs, Dr. Barton said, but she and other investigators are designing smaller devices for use in clinics. “This is exciting, because not only do we [view] subcellular structure with this modality, but it can also be highly sensitive to collagen structure,” she said.
 

Ovarian cancer model

In a model of ovarian cancer, she and colleagues externalized the ovaries of a mouse, imaged the organs, put them back in, and reassessed them at 8 weeks. “This model develops cancer very quickly,” said Dr. Barton, who once worked for McDonnell Douglas on the Space Station program. At 8 weeks, using fluorescence and targeted agents with a tabletop multiphoton microscopy system, they observed that the proliferation signals of cancer had begun. “So, with an agent targeted to the folate receptor or to other receptors that are implicated in cancer development, we can see that ovaries and fallopian tubes are lighting up,” she said.

With proof of concept established with the mouse study, she and other researchers are drawing from technological advances to create tiny laser systems for use in the clinic to image a variety of structures in the human body. Optics advances include bulk optics and all-fiber designs where engineers can create an imaging probe that’s only 125 microns in diameter, “or maybe even as small as 70 microns in diameter,” she said. “We can do fabrications on the tips of endoscopes to redirect the light and focus it. We can also do 3-D printing and spiral scanning to create miniature devices to make new advances. That means that instead of just white light imaging of the colon or the lung like we have had in the past, we can start moving into smaller structures, such as the eustachian tube, the fallopian tube, the bile ducts, or making miniature devices for brain biopsies, lung biopsies, and maybe being able to get into bronchioles and arterioles.”

According to Dr. Barton, prior research has demonstrated that cerebral vasculature can be imaged with a catheter 400 microns in diameter, the spaces in the lungs can be imaged with a needle that is 310 microns in diameter, and the inner structures of the eustachian tube can be viewed with an endoscope 1 mm in diameter.

She and her colleagues are developing an OCT/fluorescence imaging falloposcope that is 0.8 mm in diameter, flexible, and steerable, as a tool for early detection of ovarian cancer in humans. “It’s now known that most ovarian cancer starts in the fallopian tubes,” Dr. Barton said. “It’s metastatic disease when those cells break off from the fallopian tubes and go to the ovaries. We wanted to create an imaging system where we created a fiber bundle that we could navigate with white light and with fluorescence so that we can see these early stages of cancer [and] how they fluoresce differently. We also wanted to have an OCT system so that we could image through the wall of the fallopian tube and look for that layer thickening and other precursors to ovarian cancer.”

To date, in vivo testing in healthy women has demonstrated that the miniature endoscope is able to reach the fallopian tubes through the natural orifice of the vagina and uterus. “That is pretty exciting,” she said. “The images may not be of the highest quality, but we are advancing.”

Dr. Barton reported having no relevant financial disclosures.

Interventions that specifically address diabetes distress can not only improve patient mental health but can also cut costs, according to two new studies in patients with type 1 diabetes presented at the annual scientific sessions of the American Diabetes Association.

Danielle Hessler Jones, PhD, presented findings from Behavioral Approaches to Reducing Diabetes Distress and Improving Glycemic Control (EMBARK) in adults with type 1 diabetes during an oral session.

The three-arm randomized trial found that patients had the greatest improvements in feelings of powerlessness after a 3-month behavioral intervention that combined type 1 diabetes education plus specific attention to diabetes distress.

And in a late-breaking poster, “Do The Right Thing: Behavioral Intervention for At-Risk T1D Youth,” David V. Wagner, PhD, showed that a behavioral intervention not only improved glycemic management but also reduced cost of care in disadvantaged youth.

“Diabetes distress is the emotional response to living with diabetes, the burden of relentless daily self-management, and the prospect of its long-term complications,” said Dr. Hessler Jones, professor and vice chair for research in the department of family and community medicine at the University of California, San Francisco.  

It is common, experienced by 20%-58% of people with type 1 and type 2 diabetes, and is different from depression, as it is associated with glycemic control and disease management. It “is also chronic and does not disappear on its own without intervention,” she stressed.

“It is the expected worries, concerns, and fears that are associated with struggling with a demanding and progressive chronic disease and its management,” she added.

The findings from EMBARK “suggest that distress reductions are greatest when interventions integrate education alongside approaches to address the emotional side of diabetes,” she said.  

The group is also analyzing changes in A1c with the three different interventions in EMBARK, with results expected this fall.

Dr. Hessler Jones said they also just received funding for DDASSIST, which will answer the question: “How do I translate this into care in my clinic?” The aim of the clinic training program is to bring the intervention to the diabetes care team.

“Could this program be delivered by somebody else, other than a psychologist?” an audience member asked. They will be looking at this, she replied.
 

‘Do the right thing’

For the late-breaking poster by Dr. Wagner and colleagues, researchers evaluated direct cost data from three health care systems provided for youth with type 1 diabetes who received an intensive behavioral health intervention, Novel Interventions in Children’s Healthcare (NICH).

Youths were included in the analyses if they had type 1 diabetes and at least 1 year of cost data prior to and following NICH enrollment. Outpatient, emergency department, and inpatient costs were combined. The analysis included 53 youth with the following characteristics: mean age, 14.2 years; 87% Medicaid; 58% female; 32% Black, 29% Non-Hispanic White, 28% Hispanic/Latinx, 7% Pacific Islander, 2% Asian, and 2% other racial and ethnic groups.

Average yearly costs significantly decreased from $20,400 per youth prior to NICH to $9,500 per youth afterward, largely due to inpatient charges.

“These results highlight the benefits of providing access to intensive interventions to pediatric populations experiencing health disparities,” said Dr. Wagner. “Investing early in the lives of youth experiencing health disparities is not only the right thing to do to improve patients’ health but it could also have a positive economic impact down the road.”
 

Three interventions in 300 adults with type 1 diabetes

Meanwhile, EMBARK recruited 300 patients with type 1 diabetes in the United States from clinics and community organizations who were aged 21 and older and had an elevated type 1 diabetes distress score (> 2.0) and A1c greater than or equal to 7.5%.

Participants were a mean age of 46 years, 79% were female, and 89% were White. They had a type 1 diabetes distress score of 2.8, a mean A1c of 8.3%, and 71% used an insulin pump and 79% used a continuous glucose monitor.

Participants were randomized to one of three interventions:

• Streamline: A traditional diabetes educator-led education and management program.
• Tuned-in: A psychologist-led program focused exclusively on reducing diabetes distress.
• Fixit: An integration of the two programs.

Interventions were given virtually over 3 months to small groups of 8-12 individuals and included initial workshops, one-to-one phone calls, and follow-up group meetings. Participants were then followed for 8 months.  

Researchers found statistically significant and substantial reductions in overall diabetes distress in all three interventions, with the greatest reductions in the combined intervention group, which were greater than in the educational approach alone group (P = .005).

The percentage of participants who no longer reported elevated diabetes distress at follow-up was 25% in Streamline, 37% in Tuned-in, and 42% in Fixit.

The percentage of participants who reported a minimal clinically important difference – the smallest change in a treatment outcome that an individual would identify as important – was also greatest in those in the Fixit intervention group (82%) than in the Tuned-in (74%) or Streamline (65%) interventions.
 

‘Adding the psychologist is where the real magic happens’

“The certified diabetes care specialist intervention is really a very standard thing that most clinicians would have access to; they tend to focus on knowledge and problem solving and some of the psychosocial issues,” Robert Gabbay, MD, PhD, chief scientific and medical officer for the ADA, said in an interview.

The EMBARK trial found a “graded response: CDCS alone, psychologist really focused on diabetes distress, and the two together, which would be the ideal practice model,” he noted.

There are these validated ways of measuring diabetes distress using a diabetes distress survey tool, which is also underutilized.  

“Adding the psychologist is really where the real magic happens in terms of diabetes distress,” Dr. Gabbay said.

“As you can imagine, [if] somebody ... feels powerless, it is going to be tough to manage their diabetes and unlikely to be terribly successful,” he observed. Often, these individuals are just not doing well. This study highlighted the importance of identifying this.

“I’m encouraged by the findings from the studies presented during this year’s Scientific Sessions as we continue to seek out innovative, evidence-based solutions that support people living with diabetes when they need it the most,” Dr. Gabbay concluded.

Average yearly costs significantly decreased from $20,400 per youth prior to NICH to $9,500 per youth afterward, largely due to inpatient charges.

“These results highlight the benefits of providing access to intensive interventions to pediatric populations experiencing health disparities,” said Dr. Wagner. “Investing early in the lives of youth experiencing health disparities is not only the right thing to do to improve patients’ health but it could also have a positive economic impact down the road.”
 

Three interventions in 300 adults with type 1 diabetes

Meanwhile, EMBARK recruited 300 patients with type 1 diabetes in the United States from clinics and community organizations who were aged 21 and older and had an elevated type 1 diabetes distress score (> 2.0) and A1c greater than or equal to 7.5%.

Participants were a mean age of 46 years, 79% were female, and 89% were White. They had a type 1 diabetes distress score of 2.8, a mean A1c of 8.3%, and 71% used an insulin pump and 79% used a continuous glucose monitor.

Participants were randomized to one of three interventions:

• Streamline: A traditional diabetes educator-led education and management program.
• Tuned-in: A psychologist-led program focused exclusively on reducing diabetes distress.
• Fixit: An integration of the two programs.

Interventions were given virtually over 3 months to small groups of 8-12 individuals and included initial workshops, one-to-one phone calls, and follow-up group meetings. Participants were then followed for 8 months.  

Researchers found statistically significant and substantial reductions in overall diabetes distress in all three interventions, with the greatest reductions in the combined intervention group, which were greater than in the educational approach alone group (P = .005).

The percentage of participants who no longer reported elevated diabetes distress at follow-up was 25% in Streamline, 37% in Tuned-in, and 42% in Fixit.

The percentage of participants who reported a minimal clinically important difference – the smallest change in a treatment outcome that an individual would identify as important – was also greatest in those in the Fixit intervention group (82%) than in the Tuned-in (74%) or Streamline (65%) interventions.
 

‘Adding the psychologist is where the real magic happens’

“The certified diabetes care specialist intervention is really a very standard thing that most clinicians would have access to; they tend to focus on knowledge and problem solving and some of the psychosocial issues,” Robert Gabbay, MD, PhD, chief scientific and medical officer for the ADA, said in an interview.

The EMBARK trial found a “graded response: CDCS alone, psychologist really focused on diabetes distress, and the two together, which would be the ideal practice model,” he noted.

There are these validated ways of measuring diabetes distress using a diabetes distress survey tool, which is also underutilized.  

“Adding the psychologist is really where the real magic happens in terms of diabetes distress,” Dr. Gabbay said.

“As you can imagine, [if] somebody ... feels powerless, it is going to be tough to manage their diabetes and unlikely to be terribly successful,” he observed. Often, these individuals are just not doing well. This study highlighted the importance of identifying this.

“I’m encouraged by the findings from the studies presented during this year’s Scientific Sessions as we continue to seek out innovative, evidence-based solutions that support people living with diabetes when they need it the most,” Dr. Gabbay concluded.

Interventions that specifically address diabetes distress can not only improve patient mental health but can also cut costs, according to two new studies in patients with type 1 diabetes presented at the annual scientific sessions of the American Diabetes Association.

Danielle Hessler Jones, PhD, presented findings from Behavioral Approaches to Reducing Diabetes Distress and Improving Glycemic Control (EMBARK) in adults with type 1 diabetes during an oral session.

The three-arm randomized trial found that patients had the greatest improvements in feelings of powerlessness after a 3-month behavioral intervention that combined type 1 diabetes education plus specific attention to diabetes distress.

And in a late-breaking poster, “Do The Right Thing: Behavioral Intervention for At-Risk T1D Youth,” David V. Wagner, PhD, showed that a behavioral intervention not only improved glycemic management but also reduced cost of care in disadvantaged youth.

“Diabetes distress is the emotional response to living with diabetes, the burden of relentless daily self-management, and the prospect of its long-term complications,” said Dr. Hessler Jones, professor and vice chair for research in the department of family and community medicine at the University of California, San Francisco.  

It is common, experienced by 20%-58% of people with type 1 and type 2 diabetes, and is different from depression, as it is associated with glycemic control and disease management. It “is also chronic and does not disappear on its own without intervention,” she stressed.

“It is the expected worries, concerns, and fears that are associated with struggling with a demanding and progressive chronic disease and its management,” she added.

The findings from EMBARK “suggest that distress reductions are greatest when interventions integrate education alongside approaches to address the emotional side of diabetes,” she said.  

The group is also analyzing changes in A1c with the three different interventions in EMBARK, with results expected this fall.

Dr. Hessler Jones said they also just received funding for DDASSIST, which will answer the question: “How do I translate this into care in my clinic?” The aim of the clinic training program is to bring the intervention to the diabetes care team.

“Could this program be delivered by somebody else, other than a psychologist?” an audience member asked. They will be looking at this, she replied.
 

‘Do the right thing’

For the late-breaking poster by Dr. Wagner and colleagues, researchers evaluated direct cost data from three health care systems provided for youth with type 1 diabetes who received an intensive behavioral health intervention, Novel Interventions in Children’s Healthcare (NICH).

Youths were included in the analyses if they had type 1 diabetes and at least 1 year of cost data prior to and following NICH enrollment. Outpatient, emergency department, and inpatient costs were combined. The analysis included 53 youth with the following characteristics: mean age, 14.2 years; 87% Medicaid; 58% female; 32% Black, 29% Non-Hispanic White, 28% Hispanic/Latinx, 7% Pacific Islander, 2% Asian, and 2% other racial and ethnic groups.

Average yearly costs significantly decreased from $20,400 per youth prior to NICH to $9,500 per youth afterward, largely due to inpatient charges.

SAN DIEGO – A new analysis of a large-scale trial of a novel lipid-lowering agent has shown a particularly large reduction in cardiovascular events in the primary prevention population enrolled in the study, two-thirds of whom also had type 2 diabetes, leading to calls for more attention to be paid to this group of patients.

The main results of the CLEAR Outcomes trial of bempedoic acid (Nexletol, Esperion) in a mixed secondary and primary prevention population intolerant to statins, presented in March at the 2023 joint scientific sessions of the American College of Cardiology and the World Heart Federation, showed a 13% relative risk reduction in the main primary endpoint, a composite of cardiovascular death, myocardial infarction, stroke, or coronary revascularization.

This new analysis of the 4,206 high-risk primary prevention patients in the study – 67% of whom also had type 2 diabetes – has shown a 30% relative risk reduction in the same endpoint.

Other key endpoints were reduced to a similar or even greater extent, with the composite of cardiovascular death/stroke/MI showing a 36% relative risk reduction, and a 39% relative risk reduction for cardiovascular death and MI individually.

“These results are frankly striking,” lead investigator Steve Nissen, MD, said in an interview. 

“These are really large reductions. These results are telling us that high-risk primary prevention patients, although their absolute event rate is lower than secondary prevention patients, can have very impressive relative risk reductions in major cardiovascular events with lipid-lowering therapy,” he said.

But Dr. Nissen, chief academic officer at the Heart Vascular & Thoracic Institute at the Cleveland Clinic, pointed out that this population of patients is not well treated. 

“This is the problem: Less than half of high-risk primary prevention patients in the U.S., and in virtually every other developed country, are receiving cholesterol-lowering medication. These patients tend to get ignored,” he stressed. 

Asked what advice he would give to clinicians based on the current findings, Dr. Nissen said: “If a patient is at high risk of developing cardiovascular disease, particularly those with [type 2] diabetes, they need to go on a lipid-lowering drug.” 

“If patients can tolerate a statin then that should be the first choice. We know statins work, and they are now inexpensive. They are likely to give the exact same benefit as we have shown in this study with bempedoic acid, as the two drug classes work by very similar mechanisms. But if patients can’t tolerate a statin, then treat them with bempedoic acid. The bottom line is that these patients just need to be treated,” he said.
 

‘Wake-up call’

He said these new results are a “wake-up call for the medical community that we need to pay far more attention to high-risk primary prevention patients.”

Dr. Nissen does not believe the effect is specific to bempedoic acid; rather, it is more likely an effect of lowering LDL cholesterol (LDL-C) levels. 

“This message is not about bempedoic acid, in particular. We have seen similar findings in historical studies with the statins, but that seems to have been forgotten. The message is about lowering LDL in patients who are at high risk of having a first cardiovascular event. We need to identify patients at high risk for a first cardiac event and get them on a cholesterol-lowering drug – and in most cases that will be a statin.”

Dr. Nissen presented the new analysis from the CLEAR OUTCOMES trial at the annual scientific sessions of the American Diabetes Association. It was simultaneously published online in JAMA.

He pointed out that large trials of lipid-lowering therapy in the primary prevention population have not been done for many years. 

“All the contemporary trials with lipid-lowering therapy have only included secondary prevention patients and they often enroll patients after an acute coronary syndrome event.

“But for the CLEAR OUTCOMES trial, we included a significant amount of primary prevention patients – those with risk factors such as [type 2] diabetes and hypertension who are considered to be at high risk of developing cardiovascular disease,” he explained.

CLEAR OUTCOMES was a masked, randomized, trial that enrolled 13,970 statin-intolerant patients. The new analysis included 4,206 of those patients with risk factors for heart disease but without a prior cardiovascular event – the primary prevention group. The mean age of these participants was 68 years, 67% had diabetes, and 59% were women.

Treatment with bempedoic acid showed a 22% reduction in LDL-C, compared with placebo, with a reduction of 30.2 mg/dL from a mean baseline of 142.5 mg/dL. High-sensitivity C-reactive protein (CRP) levels were also reduced by 0.56 mg/L (21.5%), from a median baseline of 2.4 mg/L.

Dr. Nissen told a press briefing at the ADA meeting that he believes “it’s the combination of LDL lowering and reduction in CRP that might have been the driver [for the effects we saw in the trial]. Certainly, bempedoic acid lowers both.”

And he noted the recent U.S. approval of a new low dose of colchicine 0.5 mg (Lodoco, Agepha Pharma) with a broad indication for use in atherosclerotic cardiovascular disease (ASCVD), which represents a completely new approach to treatment, specifically targeting inflammation as a driver of atherosclerosis.

Bempedoic acid is a prodrug that works along the same pathways as statins but does not cause muscle pain, which makes many people intolerant to statins. Bempedoic acid was first approved by the Food and Drug Administration in 2020 for the treatment of adults with heterozygous familial hypercholesterolemia or established ASCVD who require additional LDL-C lowering.
 

Greater benefit in primary prevention?

In this primary prevention group, treatment with bempedoic acid for 40 months was associated with a significant risk reduction for the primary endpoint – a composite of cardiovascular death, nonfatal MI, nonfatal stroke, or coronary revascularization – which occurred in 5.3% of the treatment group versus 7.6% in the placebo group (adjusted hazard ratio, 0.70; P = .002). This represents a 30% relative risk reduction in major cardiovascular events.

Other key secondary endpoints also showed impressive reductions.

The rate of the composite endpoint of cardiovascular death, MI, or stroke was 6.4% in the placebo group and 4.0% with bempedoic acid (HR, 0.64; P < .001); MI occurred in 2.2% versus 1.4% (HR, 0.61), cardiovascular death in 3.1% versus 1.8% (HR, 0.61), and all-cause mortality in 5.2% versus 3.6% (HR, 0.73), respectively.

Adverse effects with bempedoic acid included a higher incidence of gout (2.6% vs 2.0%), cholelithiasis (2.5% vs. 1.1%), and increases in serum creatinine, uric acid, and hepatic enzyme levels.

Dr. Nissen believed these results suggest that there may be a greater benefit of lipid lowering in high-risk primary prevention patients than in the secondary prevention population.

“It may seem paradoxical, but there is actually some history that this may be the case,” he said.

He pointed out that the JUPITER trial of rosuvastatin in 2008 was the last major primary prevention trial of a lipid-lowering agent, which was stopped early with a 44% reduction of the primary endpoint.

He noted that one of the arguments against the use of statins in primary prevention is the belief that absolute risk reductions are quite modest.

“But in this analysis, we found an absolute risk reduction of 2.3% for the primary endpoint. That’s a number needed to treat to prevent 1 event of 43. That’s pretty good,” he said.

Trying to explain why there may be more benefit in the primary prevention population, Dr. Nissen suggested that these patients may have more vulnerable plaques.

“I think high-risk primary prevention patients probably have a lot of lipid-laden plaque – some people call it ‘vulnerable’ plaque. These are softer, cholesterol-laden plaque. We know that treatment with cholesterol-lowering medication causes these plaques to shrink. The lipid core is delipidated and the plaque stabilizes,” he explained. “It may be that in secondary prevention patients to some extent the horse is already out of the barn – they have advanced disease. But primary prevention patients may have plaques that are more amenable to modification by cholesterol lowering.”

He admitted that the idea is only speculation. “But that is a potential explanation for our observations.”
 

Editorial cautious

In an accompanying editorial, also published in JAMA, Dhruv S. Kazi, MD, Beth Israel Deaconess Medical Center, Boston, said the findings need to be interpreted with caution as they come from one of many subgroup analyses of a larger trial.

Dr. Kazi pointed out that the intervention and control survival curves separate right away, on the first day of follow-up, whereas the true effect of lipid-lowering therapy for primary prevention would be expected to have a somewhat delayed onset, an observation he says supports the argument that this is a chance finding.

Dr. Kazi also reminded clinicians that bempedoic acid should not be regarded as a substitute for statins, which should remain the first-line therapy for primary prevention.

“For now, available evidence suggests that, although bempedoic acid is not a perfect substitute for a statin, it is a reasonable therapeutic choice for primary prevention of ASCVD events in high-risk, statin-intolerant patients,” he concluded.

And he noted the recent U.S. approval of a new low dose of colchicine 0.5 mg (Lodoco, Agepha Pharma) with a broad indication for use in atherosclerotic cardiovascular disease (ASCVD), which represents a completely new approach to treatment, specifically targeting inflammation as a driver of atherosclerosis.

Bempedoic acid is a prodrug that works along the same pathways as statins but does not cause muscle pain, which makes many people intolerant to statins. Bempedoic acid was first approved by the Food and Drug Administration in 2020 for the treatment of adults with heterozygous familial hypercholesterolemia or established ASCVD who require additional LDL-C lowering.
 

Greater benefit in primary prevention?

In this primary prevention group, treatment with bempedoic acid for 40 months was associated with a significant risk reduction for the primary endpoint – a composite of cardiovascular death, nonfatal MI, nonfatal stroke, or coronary revascularization – which occurred in 5.3% of the treatment group versus 7.6% in the placebo group (adjusted hazard ratio, 0.70; P = .002). This represents a 30% relative risk reduction in major cardiovascular events.

Other key secondary endpoints also showed impressive reductions.

The rate of the composite endpoint of cardiovascular death, MI, or stroke was 6.4% in the placebo group and 4.0% with bempedoic acid (HR, 0.64; P < .001); MI occurred in 2.2% versus 1.4% (HR, 0.61), cardiovascular death in 3.1% versus 1.8% (HR, 0.61), and all-cause mortality in 5.2% versus 3.6% (HR, 0.73), respectively.

Adverse effects with bempedoic acid included a higher incidence of gout (2.6% vs 2.0%), cholelithiasis (2.5% vs. 1.1%), and increases in serum creatinine, uric acid, and hepatic enzyme levels.

Dr. Nissen believed these results suggest that there may be a greater benefit of lipid lowering in high-risk primary prevention patients than in the secondary prevention population.

“It may seem paradoxical, but there is actually some history that this may be the case,” he said.

He pointed out that the JUPITER trial of rosuvastatin in 2008 was the last major primary prevention trial of a lipid-lowering agent, which was stopped early with a 44% reduction of the primary endpoint.

He noted that one of the arguments against the use of statins in primary prevention is the belief that absolute risk reductions are quite modest.

“But in this analysis, we found an absolute risk reduction of 2.3% for the primary endpoint. That’s a number needed to treat to prevent 1 event of 43. That’s pretty good,” he said.

Trying to explain why there may be more benefit in the primary prevention population, Dr. Nissen suggested that these patients may have more vulnerable plaques.

“I think high-risk primary prevention patients probably have a lot of lipid-laden plaque – some people call it ‘vulnerable’ plaque. These are softer, cholesterol-laden plaque. We know that treatment with cholesterol-lowering medication causes these plaques to shrink. The lipid core is delipidated and the plaque stabilizes,” he explained. “It may be that in secondary prevention patients to some extent the horse is already out of the barn – they have advanced disease. But primary prevention patients may have plaques that are more amenable to modification by cholesterol lowering.”

He admitted that the idea is only speculation. “But that is a potential explanation for our observations.”
 

Editorial cautious

In an accompanying editorial, also published in JAMA, Dhruv S. Kazi, MD, Beth Israel Deaconess Medical Center, Boston, said the findings need to be interpreted with caution as they come from one of many subgroup analyses of a larger trial.

Dr. Kazi pointed out that the intervention and control survival curves separate right away, on the first day of follow-up, whereas the true effect of lipid-lowering therapy for primary prevention would be expected to have a somewhat delayed onset, an observation he says supports the argument that this is a chance finding.

Dr. Kazi also reminded clinicians that bempedoic acid should not be regarded as a substitute for statins, which should remain the first-line therapy for primary prevention.

“For now, available evidence suggests that, although bempedoic acid is not a perfect substitute for a statin, it is a reasonable therapeutic choice for primary prevention of ASCVD events in high-risk, statin-intolerant patients,” he concluded.

SAN DIEGO – Weekly tirzepatide injections in adults with type 2 diabetes and overweight or obesity safely led to 12.8%-14.7% in-trial weight loss after 72 weeks in the SURMOUNT-2 pivotal trial, a finding that will likely lead to Food and Drug Administration approval of a new indication for weight loss for tirzepatide.

Tirzepatide received FDA approval as a treatment for type 2 diabetes in adults, marketed as Mounjaro, in 2022. The agent – a “twincretin” that acts as an agonist at both the glucagon-like peptide-1 (GLP-1) receptor and glucose-dependent insulinotropic polypeptide (GIP) receptor – had also previously scored a decisive win for weight loss in adults with overweight or obesity without diabetes in the SURMOUNT-1 pivotal trial.

Taken together, results from SURMOUNT-1 and SURMOUNT-2 appear to make a good case for a weight-loss indication that will not depend on whether a patient also has type 2 diabetes.

“We anticipate that tirzepatide will be [FDA] approved for weight loss later this year,” W. Timothy Garvey, MD, lead researcher for SURMOUNT-2, said during a press briefing at the annual scientific sessions of the American Diabetes Association.
 

Tirzepatide ‘fills the gap’

Tirzepatide “fills the gap to get [medication-driven] weight loss in the range of 15% of baseline weight or better,” Dr. Garvey noted, which puts it in a favorable position relative to a 2.4-mg weekly subcutaneous injection with the GLP-1 agonist semaglutide (Wegovy), which produced an average weight loss from baseline of about 9.6% in people with type 2 diabetes in the STEP-2 trial.

Although tirzepatide has not been compared head-to-head for weight loss with any of the several available GLP-1 agonists, the reported weight-loss numbers seem to favor tirzepatide, said Dr. Garvey, director of the Diabetes Research Center of the University of Alabama at Birmingham.

“If you look at the degree of weight loss across trials, we see a clinically significant difference in weight loss” compared with semaglutide and other agents that only act on the GLP-1 receptor, he noted. (Although cross-trial comparisons of different medications often have uncertain reliability.)

“The data suggest an incremental effect from tirzepatide” compared with the GLP-1 agonists now approved for weight loss, said Marlon Pragnell, PhD, vice president, research and science, ADA, who was not involved in the tirzepatide studies.

This is a “step forward for treating people with obesity and type 2 diabetes; it’s a very promising treatment option,” Dr. Pragnell said in an interview.
 

Tirzepatide the ‘most effective agent’

Ildiko Lingvay, MD, the designated discussant for the SURMOUNT-2 presentation at the meeting, fully agreed. The new findings “confirm that tirzepatide is the most effective agent currently on the [U.S.] market to help achieve the two coprimary goals for patients with type 2 diabetes – weight loss and glycemic control – while also having favorable effects on cardiovascular risk factors,” said Dr. Lingvay, an endocrinologist at UT Southwestern Medical Center in Dallas, who was not involved with the SURMOUNT studies.

Dr. Lingvay offered as evidence the performance of tirzepatide’s main rival for weight loss semaglutide (Wegovy), delivered at the 2.4 mg/week subcutaneous injected dosage approved for weight loss. The semaglutide trial that SURMOUNT-2 most resembles is the STEP-2 trial, she said, which showed as its primary outcome a 9.6% average weight loss from baseline after 68 weeks of weekly semaglutide that compares, in a cross-trial way, with the 14.7% average drop from baseline weight with 15 mg tirzepatide weekly for 72 weeks and an average 12.8% weight loss with a weekly 10-mg tirzepatide dose.

“It’s fair to say that tirzepatide has an edge,” despite the limitations of cross-trial comparisons, Dr. Lingvay said in an interview.

But she acknowledged that superior weight loss efficacy takes a back seat in U.S. practice to access and affordability when making a prescribing decision for individual patients as these newer drugs are all expensive. 
 

Affordability and access will remain a ‘big problem’

Dr. Garvey, too, cautioned that access and affordability of tirzepatide as well as other GLP-1 agonists remains a major sticking point.

“These medications are very expensive – more than $1,000 a dose – and this cost limits access ... [which is] a big problem,” Dr. Garvey noted. U.S. health care payers “do not want to open the gates [to expensive treatments] for a disorder that’s as common as obesity.”

“Access and affordability are always an issue for these medications,” agreed Janet Brown-Friday, RN, president, health care and education, ADA, who had no role in the tirzepatide studies.

SURMOUNT-2 randomized 938 adults with type 2 diabetes and overweight or obesity at 77 centers in seven countries including the United States from March 2021 to April 2023. The study had two primary outcomes: Average percent change in body weight from baseline to week 72, and percentage of participants who achieved a weight reduction from baseline of at least 5% after 72 weeks.
 

In-trial weight loss of 12.8%-14.7%

The in-trial analysis showed that a 10-mg weekly subcutaneous dose of tirzepatide resulted in an average 12.8% weight loss from baseline, and a 15-mg weekly subcutaneous dose led to an average 14.7% drop from baseline weight. People randomized to receive a placebo injection averaged a 3.2% drop from their baseline weight after 72 weeks, a finding that documents significant improvements compared with placebo with both tirzepatide doses.

The percentage of patients who achieved at least a 5% reduction in weight from baseline was 79% with the 10-mg dose of tirzepatide, 83% with the 15-mg dose, and 32% with placebo; these improvements were significant for both tirzepatide doses compared with placebo.

A 15% or greater reduction in weight from baseline occurred in 40%-48% of people who received tirzepatide compared with 3% of those who received placebo. A reduction in weight of this magnitude from baseline “will prevent a broad array of complications,” Dr. Garvey noted.

The results were simulatenously published online in The Lancet.
 

Glucose control without severe hypoglycemia

The safety profile of tirzepatide in SURMOUNT-2 was consistent with prior studies of the agent, as well as with other medications in the GLP-1 agonist class, with gastrointestinal adverse effects such as nausea and vomiting predominating, especially during the dose-escalation phase at treatment onset.

Dr. Garvey especially highlighted the overall safety of tirzepatide, and particularly its ability to produce clinically important reductions in A1c that averaged more than two percentage points from baseline values without producing a single episode of severe hypoglycemia, and an incidence of milder hypoglycemia of less than a 5%.

The absence of any severe hypoglycemia was “amazing,” Dr. Garvey said, especially given that 46%-49% of people taking tirzepatide in SURMOUNT-2 achieved normalization of their A1c to less than 5.7% on treatment compared with 4% of participants taking placebo.

The results also showed the benefit of a “big reduction in fasting insulin levels,” which averaged a 41% cut from baseline in those who received the 15-mg subcutaneous weekly dose of tirzepatide, coupled with increased insulin sensitivity, Dr. Garvey said.

Dr. Garvey disclosed ties to Eli Lilly, which sponsored SURMOUNT-2 and markets tirzepatide (Mounjaro), as well Boehringer Ingelheim, Novo Nordisk, Pfizer, Fractyl Health, Alnylam Pharmaceuticals, Inogen, and Merck. He has been an investigator for studies sponsored by Novo Nordisk, Epitomee, Neurovalens, and Pfizer. Dr. Pragnell and Dr. Brown-Friday have disclosed no relevant financial relationships.

Despite increased societal gains, transgender individuals are still a medically and socially underserved group. The historic rise of antitransgender legislation and the overturning of Roe v. Wade, further compound existing health care disparities, particularly in the realm of contraception and pregnancy. Obstetrician-gynecologists and midwives are typically first-line providers when discussing family planning and fertility options for all patients assigned female at birth. Unfortunately, compared with the surgical, hormonal, and mental health aspects of gender-affirming care, fertility and pregnancy in transgender men is still a relatively new and under-researched topic.

Only individuals who are assigned female at birth and have a uterus are capable of pregnancy. This can include both cisgender women and nonbinary/transgender men. However, societal and medical institutions are struggling with this shift in perspective from a traditionally gendered role to a more inclusive one. Obstetrician-gynecologists and midwives can serve to bridge this gap between these patients and societal misconceptions surrounding transgender men who desire and experience pregnancy.

Providers need to remember that many transmasculine individuals will still retain their uterus and are therefore capable of getting pregnant. While testosterone causes amenorrhea, if patients are engaging in penile-vaginal intercourse, conception is still possible. If a patient does not desire pregnancy, all contraceptive options available for cisgender women, which also include combined oral contraceptives, should be offered.

For patients seeking to become pregnant, testosterone must be discontinued. Testosterone is teratogenic; it can cause abnormal urogenital development in the female fetus and should be avoided even prior to conception.^1,2 The timing of testosterone discontinuation is debatable. There are no well-established guidelines dictating how early pregnancy can be attempted after cessation of testosterone, but typically if menses has resumed, the teratogenic effects of testosterone are less likely.

For amenorrheic patients on testosterone, menses will occur, on average, 3-6 months after testosterone is stopped. Of note, the longer that testosterone has been suspended, the greater the likelihood of achieving pregnancy.³ In a study by Light et al., 72% of patients conceived within 6 months of attempting pregnancy, 80% resumed menses within 6 months of stopping testosterone, and 20% of individuals conceived while they were amenorrheic from testosterone.⁴

Psychosocial support is an essential part of pregnancy care in transgender men. For some patients, pregnancy can worsen gender dysphoria, whereas others are empowered by the experience. Insurance companies may also deny obstetric care services to transgender males who have already changed their gender marker from female to male on insurance policies.

Whether transmasculine individuals are at higher risk for pregnancy complications is largely unknown, although emerging research in this field has yielded interesting results. While testosterone can cause vaginal atrophy, it does not seem to increase a patient’s risk of vaginal lacerations or their ability to have a successful vaginal delivery. For transgender men with significant discomfort around their genitalia, an elective cesarean section may be appropriate.⁵

More recently, Stroumsa et al. conducted an analysis of all deliveries at a Michigan institution from 2014 to 2018. Patients with male gender at the time of delivery or with the diagnostic code of gender dysphoria were identified as transgender.⁶ The primary outcome of this study was severe parental morbidity (such as amniotic fluid embolism, acute myocardial infarction, eclampsia, etc.), with secondary outcomes investigating rates of cesarean delivery and preterm birth.

During this time period, the researchers identified 256 transgender patients and 1.3 million cisgender patients in their Medicaid database and 1,651 transgender patients and 1.5 million cisgender patients in the commercial database who had experienced a delivery.⁶ Compared with cisgender patients, transgender patients in the Medicaid database were younger, less likely to be white, and more likely to have a chronic condition.⁶ Compared with cisgender patients in the commercial database, transgender patients experienced higher rates of anxiety and depression.⁶ Both transgender and cisgender patients had similar rates of severe parental morbidity. Ironically, rates of cesarean delivery were lower, compared with cisgender patients, in both the Medicaid and commercial databases, with no differences observed between rates of preterm birth.⁶

While more research is needed on pregnancy in transgender men, this analysis is not only one of the largest to date, but it also challenges many misconceptions providers have regarding pregnancy outcomes. Even though transmasculine patients may require additional medical interventions to achieve pregnancy, such as assisted reproductive technology, or increased psychosocial support during the process, these initial studies are reassuring. Based on current evidence, these patients are not at greater risk for perinatal complications than their cisgender counterparts.

Despite these encouraging findings, there are still several challenges faced by transgender men when it comes to getting pregnant. For instance, they may have difficulty accessing fertility services because of financial constraints or experience a lack of awareness or prejudice from providers; they might also be subject to discrimination or stigma within health care settings. As front-line providers for obstetrical care, we must lead the way towards improving the care for pregnant transmasculine individuals.

Despite increased societal gains, transgender individuals are still a medically and socially underserved group. The historic rise of antitransgender legislation and the overturning of Roe v. Wade, further compound existing health care disparities, particularly in the realm of contraception and pregnancy. Obstetrician-gynecologists and midwives are typically first-line providers when discussing family planning and fertility options for all patients assigned female at birth. Unfortunately, compared with the surgical, hormonal, and mental health aspects of gender-affirming care, fertility and pregnancy in transgender men is still a relatively new and under-researched topic.

Only individuals who are assigned female at birth and have a uterus are capable of pregnancy. This can include both cisgender women and nonbinary/transgender men. However, societal and medical institutions are struggling with this shift in perspective from a traditionally gendered role to a more inclusive one. Obstetrician-gynecologists and midwives can serve to bridge this gap between these patients and societal misconceptions surrounding transgender men who desire and experience pregnancy.

Providers need to remember that many transmasculine individuals will still retain their uterus and are therefore capable of getting pregnant. While testosterone causes amenorrhea, if patients are engaging in penile-vaginal intercourse, conception is still possible. If a patient does not desire pregnancy, all contraceptive options available for cisgender women, which also include combined oral contraceptives, should be offered.

For patients seeking to become pregnant, testosterone must be discontinued. Testosterone is teratogenic; it can cause abnormal urogenital development in the female fetus and should be avoided even prior to conception.^1,2 The timing of testosterone discontinuation is debatable. There are no well-established guidelines dictating how early pregnancy can be attempted after cessation of testosterone, but typically if menses has resumed, the teratogenic effects of testosterone are less likely.

For amenorrheic patients on testosterone, menses will occur, on average, 3-6 months after testosterone is stopped. Of note, the longer that testosterone has been suspended, the greater the likelihood of achieving pregnancy.³ In a study by Light et al., 72% of patients conceived within 6 months of attempting pregnancy, 80% resumed menses within 6 months of stopping testosterone, and 20% of individuals conceived while they were amenorrheic from testosterone.⁴

Psychosocial support is an essential part of pregnancy care in transgender men. For some patients, pregnancy can worsen gender dysphoria, whereas others are empowered by the experience. Insurance companies may also deny obstetric care services to transgender males who have already changed their gender marker from female to male on insurance policies.

Whether transmasculine individuals are at higher risk for pregnancy complications is largely unknown, although emerging research in this field has yielded interesting results. While testosterone can cause vaginal atrophy, it does not seem to increase a patient’s risk of vaginal lacerations or their ability to have a successful vaginal delivery. For transgender men with significant discomfort around their genitalia, an elective cesarean section may be appropriate.⁵

More recently, Stroumsa et al. conducted an analysis of all deliveries at a Michigan institution from 2014 to 2018. Patients with male gender at the time of delivery or with the diagnostic code of gender dysphoria were identified as transgender.⁶ The primary outcome of this study was severe parental morbidity (such as amniotic fluid embolism, acute myocardial infarction, eclampsia, etc.), with secondary outcomes investigating rates of cesarean delivery and preterm birth.

During this time period, the researchers identified 256 transgender patients and 1.3 million cisgender patients in their Medicaid database and 1,651 transgender patients and 1.5 million cisgender patients in the commercial database who had experienced a delivery.⁶ Compared with cisgender patients, transgender patients in the Medicaid database were younger, less likely to be white, and more likely to have a chronic condition.⁶ Compared with cisgender patients in the commercial database, transgender patients experienced higher rates of anxiety and depression.⁶ Both transgender and cisgender patients had similar rates of severe parental morbidity. Ironically, rates of cesarean delivery were lower, compared with cisgender patients, in both the Medicaid and commercial databases, with no differences observed between rates of preterm birth.⁶

While more research is needed on pregnancy in transgender men, this analysis is not only one of the largest to date, but it also challenges many misconceptions providers have regarding pregnancy outcomes. Even though transmasculine patients may require additional medical interventions to achieve pregnancy, such as assisted reproductive technology, or increased psychosocial support during the process, these initial studies are reassuring. Based on current evidence, these patients are not at greater risk for perinatal complications than their cisgender counterparts.

Despite these encouraging findings, there are still several challenges faced by transgender men when it comes to getting pregnant. For instance, they may have difficulty accessing fertility services because of financial constraints or experience a lack of awareness or prejudice from providers; they might also be subject to discrimination or stigma within health care settings. As front-line providers for obstetrical care, we must lead the way towards improving the care for pregnant transmasculine individuals.

While people living with rare cancers continue to face daunting obstacles, progress is being made, and there are reasons to hope for a better future. Advances in genomic testing and precision medicine provide increasing evidence that rare cancers can be more efficiently and effectively diagnosed and treated. Genomic tests examine tumor DNA to identify mutations that are unique to an individual’s cancer. This genetic information enables a more precise diagnosis and targeted treatment approach. Jim Palma, Co-Lead of the NORD Rare Cancer Coalition, said “There is promise for rare cancer patients due to increased legislative efforts to cover the costs of genomic testing coupled by an increase in FDA approvals for targeted and tissue agnostic therapies.”

In 2019, the National Cancer Institute established MyPART, a vast pediatric and adult rare tumor network that aims to bolster patient involvement in research and develop effective therapies through tumor sample collection, shared data, shared samples, new methods to test treatments, and new trial designs. In 2022, MyPART welcomed NORD’s Rare Cancer Coalition as an advocacy partner.

Meanwhile, advocacy organizations are giving rare cancer a rising voice. NORD’s Rare Cancer Coalition unites rare cancer patient advocacy organizations and helps them drive progress together. The coalition promotes research and awareness through its annual Rare Cancer Day (September 30) campaign. Additionally, NORD has produced over 22 continuing medical education modules on rare cancers in collaboration with PlatformQ Health, providing updates on new therapies and treatment approaches. NORD also offers rare disease reports and educational videos on rare cancers, sessions inclusive of rare cancer topics at the annual NORD Summit, and a quarterly e-newsletter, “Caring for Rare” for healthcare professionals.

MADRID – Artificial intelligence (AI) is a significant ally in dermatology and will become an indispensable component of consultations within 4 or 5 years. There are endless possibilities within the dermoverse (a term coined by joining “dermatology” and “metaverse”), from a robot office assistant to the brand new world it offers for virtual training and simulation.

A group of dermatologists expert in new technologies came together at the 50th National Congress of the Spanish Academy for Dermatology and Venereology to discuss the metaverse: that sum of all virtual spaces that bridges physical and digital reality, where users interact through their avatars and where these experts are discovering new opportunities for treating their patients. The metaverse and AI offer a massive opportunity for improving telehealth visits, immersive surgical planning, or virtual training using 3-D skin models. These are just a few examples of what this technology may eventually provide.

“The possibilities offered by the metaverse in the field of dermatology could be endless,” explained Miriam Fernández-Parrado, MD, dermatologist at Navarre Hospital, Pamplona, Spain. To her, “the metaverse could mean a step forward in teledermatology, which has come of age as a result of the pandemic.” These past few years have shown that it’s possible to perform some screenings online. This, in turn, has produced significant time and cost savings, along with greater efficacy in initial screening and early detection of serious diseases.

The overall percentage of cases that are potentially treatable in absentia is estimated to exceed 70%. “This isn’t a matter of replacing in-person visits but of finding a quality alternative that, far from dehumanizing the doctor-patient relationship, helps to satisfy the growing need for this relationship,” said Dr. Fernández-Parrado.
 

Always on duty

Julián Conejo-Mir, MD, PhD, professor and head of dermatology at the Virgen del Rocío Hospital in Seville, Spain, told this news organization that AI will help with day-to-day interactions with patients. It’s already a reality. “But to say that with a simple photo, we can address 70% of dermatology cases without being physically present with our patients – I don’t think that will become a reality in the next 20 years.”

Currently, algorithms can identify tumors with high success rates (80%-90%) using photographs and dermoscopic images; rates increase significantly when both kinds of images are available. These high success rates are possible because tumor morphology is stationary. “However, for inflammatory conditions, accurate diagnosis generally doesn’t exceed 60%, since these are conditions in which morphology can change a lot from one day to the next and can vary significantly, depending on their anatomic location or the patient’s age.”

Maybe once metaclinics, with 3-D virtual reality, have been established and clinicians can see the patient in real time from their offices, the rate of accurate diagnosis will reach 70%, especially with patients who have limited mobility or who live at a distance from the hospital. “But that’s still 10-15 years away, since more powerful computers are needed, most likely quantum computers,” cautioned Dr. Conejo-Mir.

The patient’s ally

In clinical practice, facilitating access to the dermoverse may help reduce pain and divert the patient’s attention, especially during in-person visits that require bothersome or uncomfortable interventions. “This is especially effective in pediatric dermatology, since settings of immersive virtual reality may contribute to relaxation among children,” explained Dr. Fernández-Parrado. She also sees potential applications among patients who need surgery. The metaverse would allow them to preview a simulation of their operation before undergoing it, thus reducing their anxiety and allaying their fears about these procedures.

Two lines are being pursued: automated diagnosis for telehealth consultations, which are primarily for tumors, and robotic office assistants.

“We have been using the first one in clinical practice, and we can achieve a success rate of 85%-90%.” The second one is much more complex, “and we’re having a hard time moving it forward within our research team, since it doesn’t involve only one algorithm. Instead, it requires five algorithms working together simultaneously (chatbot, automatic writing, image analysis, selecting the most appropriate treatment, ability to make recommendations, and even an additional one involving feelings),” explained Dr. Conejo-Mir.
 

A wise consultant

Dr. Conejo-Mir offered examples of how this might work in the near future. “In under 5 years, you’ll be able to sit in front of a computer or your smartphone, talk to an avatar that we’re able to select (sex, appearance, age, kind/serious), show the avatar your lesions, and it will tell us a basic diagnostic impression and even the treatment.”

With virtual learning, physicians can also gather knowledge or take refresher courses, using skin models in augmented reality with tumors and other skin lesions, or using immersive simulation courses that aid learning. Digital models that replicate the anatomy and elasticity of the skin or other characteristics unique to the patient can be used to reach decisions regarding surgeries and to practice interventions before entering the operating room, explained Dr. Fernández-Parrado.
 

Optimal virtual training

Virtual reality and simulation will doubtless play a major role in this promising field of using these devices for training purposes. “There will be virtual dermatology clinics or metaclinics, where you can do everything with virtual simulated patients, from gaining experience in interviews or health histories (even with patients who are difficult to deal with), to taking biopsies and performing interventions,” said Dr. Conejo-Mir.

A recent study titled “How the World Sees the Metaverse and Extended Reality” gathered data from 29 countries regarding the next 10 years. One of the greatest benefits of this technology is expected in health resources (59%), even more than in the trading of digital assets. While it is difficult to predict when the dermoverse will be in operation, Dr. Fernández-Parrado says she’s a techno-optimist. Together with Dr. Héctor Perandones, MD, a dermatologist at the University Healthcare Complex in León, Spain, and coauthor with Dr. Fernández-Parrado of the article, “A New Universe in Dermatology: From Metaverse to Dermoverse,” she’s convinced that “if we can imagine it, we can create it.”
 

A differential diagnostician

Over the past 10 years, AI has become a major ally of dermatology, providing new techniques that simplify the diagnosis and treatment of patients. There are many applications for which it adds tremendous value in dermatology: establishing precise differential diagnoses for common diseases, such as psoriasis, atopic dermatitis, or acne; eveloping personalized therapeutic protocols; and predicting medium- and long-term outcomes.

Furthermore, in onco-dermatology, AI has helped to automate the diagnosis of skin tumors by making it possible to differentiate between melanocytic and nonmelanocytic lesions. This distinction promotes early diagnosis and helps produce screening systems that are capable of prioritizing cases on the basis of their seriousness.

When asked whether any group has published any promising tools with good preliminary results, Dr. Conejo-Mir stated that his group has produced three articles that have been published in top-ranking journals. In these articles, “we explain our experience with artificial intelligence in Mohs surgery, in automated diagnosis, and for calculating the thickness of melanomas.” The eight-person research team, which comprises dermatologists and software engineers, has been working together in this area for the past 4 years.
 

Aesthetic dermatology

Unlike other specialists, dermatologists have 4-D vision when it comes to aesthetics, since they are also skin experts. AI plays a major role in aesthetic dermatology. It supports this specialty by providing a greater analytic capacity and by evaluating the procedure and technique to be used. “It’s going to help us think and make decisions. It has taken great strides in aesthetic dermatology, especially when it comes to techniques and products. There have been products like collagen, hyaluronic acid, then thread lifts ... Also, different techniques have been developed, like Botox, for example. Before, Botox was given following one method. Now, there are other methods,” explained Dr. Conejo-Mir.

He explained, “We have analyzed the facial image to detect wrinkles, spots, enlarged pores, et cetera, to see whether there are any lesions, and, depending on what the machine says you have, it provides you with a personalized treatment. It tells you the pattern of care that the patient should follow. It also tells you what you’re going to do, whether or not there is any problem, depending on the location and on what the person is like, et cetera. Then, for follow-up, you’re given an AI program that tells you if you’re doing well or not. Lastly, it gives you product recommendations.

“We are among the specialties that are going through the most change,” said Dr. Conejo-Mir.
 

An intrusive technology?

AI will be a tremendous help in decision-making, to the point where “in 4 or 5 years, it will become indispensable, just like the loupe in years past, and then the dermatoscope.” However, the machine will have to depend on human beings. “They won’t replace us, but they will become unavoidable assistants in our day-to-day medical practice.”

Questions have arisen regarding the potential dangers of these new technologies, like that of reducing the number of dermatologists within the population, and whether they might encourage intrusiveness. Dr. Conejo-Mir made no bones about it. “AI will never cut back the number of specialists. That is false. When AI supports us in teledermatology, even currently on our team, it spits out information, but the one making the decision is the practitioner, not the machine.”

AI is a tool but is not in itself something that treats patients. It is akin to the dermatoscope. Dermatologists use these tools every day, and they help arrive at diagnoses in difficult cases, but they are not a replacement for humans. “At least for the next 50 years, then we’ll see. In 2050 is when they say AI will surpass humans in its intelligence and reasoning capacity,” said Dr. Conejo-Mir.

MADRID – Artificial intelligence (AI) is a significant ally in dermatology and will become an indispensable component of consultations within 4 or 5 years. There are endless possibilities within the dermoverse (a term coined by joining “dermatology” and “metaverse”), from a robot office assistant to the brand new world it offers for virtual training and simulation.

A group of dermatologists expert in new technologies came together at the 50th National Congress of the Spanish Academy for Dermatology and Venereology to discuss the metaverse: that sum of all virtual spaces that bridges physical and digital reality, where users interact through their avatars and where these experts are discovering new opportunities for treating their patients. The metaverse and AI offer a massive opportunity for improving telehealth visits, immersive surgical planning, or virtual training using 3-D skin models. These are just a few examples of what this technology may eventually provide.

“The possibilities offered by the metaverse in the field of dermatology could be endless,” explained Miriam Fernández-Parrado, MD, dermatologist at Navarre Hospital, Pamplona, Spain. To her, “the metaverse could mean a step forward in teledermatology, which has come of age as a result of the pandemic.” These past few years have shown that it’s possible to perform some screenings online. This, in turn, has produced significant time and cost savings, along with greater efficacy in initial screening and early detection of serious diseases.

The overall percentage of cases that are potentially treatable in absentia is estimated to exceed 70%. “This isn’t a matter of replacing in-person visits but of finding a quality alternative that, far from dehumanizing the doctor-patient relationship, helps to satisfy the growing need for this relationship,” said Dr. Fernández-Parrado.
 

Always on duty

Julián Conejo-Mir, MD, PhD, professor and head of dermatology at the Virgen del Rocío Hospital in Seville, Spain, told this news organization that AI will help with day-to-day interactions with patients. It’s already a reality. “But to say that with a simple photo, we can address 70% of dermatology cases without being physically present with our patients – I don’t think that will become a reality in the next 20 years.”

Currently, algorithms can identify tumors with high success rates (80%-90%) using photographs and dermoscopic images; rates increase significantly when both kinds of images are available. These high success rates are possible because tumor morphology is stationary. “However, for inflammatory conditions, accurate diagnosis generally doesn’t exceed 60%, since these are conditions in which morphology can change a lot from one day to the next and can vary significantly, depending on their anatomic location or the patient’s age.”

Maybe once metaclinics, with 3-D virtual reality, have been established and clinicians can see the patient in real time from their offices, the rate of accurate diagnosis will reach 70%, especially with patients who have limited mobility or who live at a distance from the hospital. “But that’s still 10-15 years away, since more powerful computers are needed, most likely quantum computers,” cautioned Dr. Conejo-Mir.

The patient’s ally

In clinical practice, facilitating access to the dermoverse may help reduce pain and divert the patient’s attention, especially during in-person visits that require bothersome or uncomfortable interventions. “This is especially effective in pediatric dermatology, since settings of immersive virtual reality may contribute to relaxation among children,” explained Dr. Fernández-Parrado. She also sees potential applications among patients who need surgery. The metaverse would allow them to preview a simulation of their operation before undergoing it, thus reducing their anxiety and allaying their fears about these procedures.

Two lines are being pursued: automated diagnosis for telehealth consultations, which are primarily for tumors, and robotic office assistants.

“We have been using the first one in clinical practice, and we can achieve a success rate of 85%-90%.” The second one is much more complex, “and we’re having a hard time moving it forward within our research team, since it doesn’t involve only one algorithm. Instead, it requires five algorithms working together simultaneously (chatbot, automatic writing, image analysis, selecting the most appropriate treatment, ability to make recommendations, and even an additional one involving feelings),” explained Dr. Conejo-Mir.
 

A wise consultant

Dr. Conejo-Mir offered examples of how this might work in the near future. “In under 5 years, you’ll be able to sit in front of a computer or your smartphone, talk to an avatar that we’re able to select (sex, appearance, age, kind/serious), show the avatar your lesions, and it will tell us a basic diagnostic impression and even the treatment.”

With virtual learning, physicians can also gather knowledge or take refresher courses, using skin models in augmented reality with tumors and other skin lesions, or using immersive simulation courses that aid learning. Digital models that replicate the anatomy and elasticity of the skin or other characteristics unique to the patient can be used to reach decisions regarding surgeries and to practice interventions before entering the operating room, explained Dr. Fernández-Parrado.
 

Optimal virtual training

Virtual reality and simulation will doubtless play a major role in this promising field of using these devices for training purposes. “There will be virtual dermatology clinics or metaclinics, where you can do everything with virtual simulated patients, from gaining experience in interviews or health histories (even with patients who are difficult to deal with), to taking biopsies and performing interventions,” said Dr. Conejo-Mir.

A recent study titled “How the World Sees the Metaverse and Extended Reality” gathered data from 29 countries regarding the next 10 years. One of the greatest benefits of this technology is expected in health resources (59%), even more than in the trading of digital assets. While it is difficult to predict when the dermoverse will be in operation, Dr. Fernández-Parrado says she’s a techno-optimist. Together with Dr. Héctor Perandones, MD, a dermatologist at the University Healthcare Complex in León, Spain, and coauthor with Dr. Fernández-Parrado of the article, “A New Universe in Dermatology: From Metaverse to Dermoverse,” she’s convinced that “if we can imagine it, we can create it.”
 

A differential diagnostician

Over the past 10 years, AI has become a major ally of dermatology, providing new techniques that simplify the diagnosis and treatment of patients. There are many applications for which it adds tremendous value in dermatology: establishing precise differential diagnoses for common diseases, such as psoriasis, atopic dermatitis, or acne; eveloping personalized therapeutic protocols; and predicting medium- and long-term outcomes.

Furthermore, in onco-dermatology, AI has helped to automate the diagnosis of skin tumors by making it possible to differentiate between melanocytic and nonmelanocytic lesions. This distinction promotes early diagnosis and helps produce screening systems that are capable of prioritizing cases on the basis of their seriousness.

When asked whether any group has published any promising tools with good preliminary results, Dr. Conejo-Mir stated that his group has produced three articles that have been published in top-ranking journals. In these articles, “we explain our experience with artificial intelligence in Mohs surgery, in automated diagnosis, and for calculating the thickness of melanomas.” The eight-person research team, which comprises dermatologists and software engineers, has been working together in this area for the past 4 years.
 

Aesthetic dermatology

Unlike other specialists, dermatologists have 4-D vision when it comes to aesthetics, since they are also skin experts. AI plays a major role in aesthetic dermatology. It supports this specialty by providing a greater analytic capacity and by evaluating the procedure and technique to be used. “It’s going to help us think and make decisions. It has taken great strides in aesthetic dermatology, especially when it comes to techniques and products. There have been products like collagen, hyaluronic acid, then thread lifts ... Also, different techniques have been developed, like Botox, for example. Before, Botox was given following one method. Now, there are other methods,” explained Dr. Conejo-Mir.

He explained, “We have analyzed the facial image to detect wrinkles, spots, enlarged pores, et cetera, to see whether there are any lesions, and, depending on what the machine says you have, it provides you with a personalized treatment. It tells you the pattern of care that the patient should follow. It also tells you what you’re going to do, whether or not there is any problem, depending on the location and on what the person is like, et cetera. Then, for follow-up, you’re given an AI program that tells you if you’re doing well or not. Lastly, it gives you product recommendations.

“We are among the specialties that are going through the most change,” said Dr. Conejo-Mir.
 

An intrusive technology?

AI will be a tremendous help in decision-making, to the point where “in 4 or 5 years, it will become indispensable, just like the loupe in years past, and then the dermatoscope.” However, the machine will have to depend on human beings. “They won’t replace us, but they will become unavoidable assistants in our day-to-day medical practice.”

Questions have arisen regarding the potential dangers of these new technologies, like that of reducing the number of dermatologists within the population, and whether they might encourage intrusiveness. Dr. Conejo-Mir made no bones about it. “AI will never cut back the number of specialists. That is false. When AI supports us in teledermatology, even currently on our team, it spits out information, but the one making the decision is the practitioner, not the machine.”

AI is a tool but is not in itself something that treats patients. It is akin to the dermatoscope. Dermatologists use these tools every day, and they help arrive at diagnoses in difficult cases, but they are not a replacement for humans. “At least for the next 50 years, then we’ll see.
