We need more diverse students — more students from disadvantaged and underrepresented backgrounds in medical school. That is not a controversial take. That’s not even a new thought.

What is a hot take, however, is that free medical school alone is not going to accomplish this goal. In fact, based on data and what people think and are saying, that’s just reality.

I recently chatted about whether or not free medical school would motivate more students to pursue primary care. That was New York University’s (NYU’s) goal. If you haven’t seen that video, check it out. Now I want to explore whether free medical school would actually create a more diverse medical student body.

This topic is especially important now because, in 2023, the Supreme Court ended affirmative action for college admissions, and this naturally has a downstream effect when it comes to getting into medical school. Right now, about 6% of US physicians are Black or Hispanic/Latina, and around 0.1%-0.3% identify as Indigenous Americans, Native Hawaiians, or Pacific Islanders.

Is free medical school the answer? Well, that’s based on a huge assumption that the cost of medical school — incoming debt — is the single greatest barrier for students from diverse backgrounds, as if every single student from every background had the same level of resources in the same opportunity and were all equally competitive prior to applying, and just the prospect of debt is what caused the disparity. I don’t know if that’s reality. Let’s take a look at NYU.

After the free tuition announcement, total applications to the medical school went up nearly 50%. And from underrepresented groups, it was 100%. In 2019, the associate dean for admissions said, “A key driver was to remove a financial disincentive that dissuades people from pursuing a path in medicine.” But the acceptance rate stayed under 3%, and the average Medical College Admission Test (MCAT) and grade point average (GPA) to get in went up. Basically, the school just became more competitive.

I will always commend anyone, anywhere, who is making medical school more affordable and more accessible. With NYU, it seems a tuition gift just made it harder for students from disadvantaged backgrounds to actually get in. I mean, congratulations, you got more applications. This probably helped in ratings, and you got mentioned in news headlines, but are you actually achieving your mission?

At NYU, over the last few years, Black students made up about 11% of the medical school class, which is actually down from 2017 before the tuition gift. Students from low-income backgrounds, whom this would really benefit, used to make up around 12% of the class prior to the free tuition announcement, and now it’s around 3%-7%.

According to students from underrepresented backgrounds, the outreach and the equal opportunity need to start way earlier. The K-12 process needs to be addressed, as do mentorship opportunities and guidance throughout college, MCAT prep, resources for interviews, research opportunities, and so much more.

The following quote is from an interview with an interventional cardiology fellow who came here as a refugee: “For me, growing up, basic necessities like a quiet study space, high-speed internet, healthy meals and proper sleep were luxuries of which I could only dream. After resettling in the US as a political refugee, I lived in circumstances where such comforts were out of reach, and my path to medical school seemed insurmountable.” 

I also spoke to a friend in pediatric cancer, Michael Galvez, MD, who was outspoken about the need to improve representation in medicine, about what he thought would actually work to diversify medical schools. He mentioned adversity scores or looking at the distance traveled for applicants, as well as efforts to recruit from local, state, and community colleges, which often reflect local underserved populations. 

Dr. Galvez also agreed that although such metrics as GPA and MCAT are important, medical schools should also consider the impact applicants may have had for local, underserved communities and life experiences that may represent significant potential contributions applicants can make for public health.

The effort needs to start early. If we take a look at one of the most diverse medical schools in the country, UC Davis, we can see how this makes a difference. At UC Davis, in the class of 2026, about half of the 133 students come from underrepresented backgrounds in medicine. I’m taking a look at their website from the Office of Student and Resident Diversity, and it lists:

• K-12 outreach programs
• Undergraduate and community college programs
• Specific plans for postbaccalaureate students
• Support systems
• Resources for students that extend far beyond just premedical students

My home institution, Stanford School of Medicine, has similar programs as well, with similar ways for students from underrepresented backgrounds to find support and mentorship. This all makes a huge difference.

Regarding the actual admissions process for medical school, I’ll highlight the Johns Hopkins School of Medicine and the adaptions they’ve made to create a more fair and holistic process. It includes:

• A clear mission statement about diversity enhancement
• Anonymous voting
• A larger group to avoid bias
• Not showing academic metrics to interviewers
• Implicit association tests and trainings
• Removing photos from applications
• Appointing women, minorities, and young people with less implicit bias to the committees

Does this seem like a lot? It is, because a comprehensive approach is what it takes to build a more diverse US physician workforce, which will provide more culturally competent care, empower future generations, break down barriers and disparities in health care, and ultimately improve public health. Free tuition is awesome. I’m jealous. But on its own to solve these problems? This all feels like a misguided attempt.

Binge-eating disorder is more prevalent in women than men and has one of the strongest associations with obesity; among patients with obesity, lifetime prevalence of binge eating is approximately 5.5%. Large population studies suggest that binge-eating disorder may be present in 2%-4% of adolescents, with a mean age of onset of 12-13 years. This patient probably had milder binge-eating disorder as an adolescent and young adult, which was exacerbated by the pandemic. 

Both new diagnoses and reports of clinical worsening in patients with preexisting diagnoses of binge-eating disorder during the pandemic have been documented. Food insecurity has been associated with binge eating, consistent with this patient's anxiety over food and grocery availability during the pandemic. The definition of binge-eating disorder includes recurrent specific episodes of overeating that are not consistent with the patient's usual behavior, eating to the point of being uncomfortably full, eating more quickly or when not hungry, and having feelings of loss of control during episodes and of guilt or disgust afterward. 

Obesity and eating disorders share some common risk factors and approaches to management. Binge eating has been associated with type 2 diabetes, hypertension, asthma, sleep disorders, and menstrual disorders, all of which are also affected by obesity. The presence of both conditions increases the adverse outcomes associated with each, including negative impacts on cardiometabolic and psychological health. Workup of patients presenting with binge eating and obesity should always include complete blood/metabolic panels and cardiovascular and renal health, as well as assessments of nutrition status, electrolyte imbalances, gastrointestinal reflux disease, and chronic pain.

In general, where binge-eating disorder and obesity are concurrent, cognitive-behavioral therapy (CBT) for binge-eating disorder should be the first priority, with obesity management (medication or surgery) to follow. CBT has the strongest evidence of benefit for patients with binge-eating disorder and is the recommended treatment approach. Other psychotherapeutic interventions that may be of benefit include dialectical behavioral therapy (to reduce binge-eating frequency), technology-based options, and family-based therapy when symptoms are recognized in children or adolescents. Structured behavioral weight management strategies for management of obesity and overweight do not increase symptoms of eating disorders and may instead relieve some symptoms. An emerging approach to binge eating in patients with obesity is CBT that integrates therapeutic approaches to both issues. 

Medications to treat binge-eating disorder are limited and should not be used without concurrent psychotherapy; lisdexamfetamine has demonstrated benefit, is recommended by the American Psychiatric Association, and is approved by the US Food and Drug Administration specifically to treat adults with binge-eating disorder. 

The success of psychological interventions and lifestyle modifications for obesity is heavily dependent on the individual's ability and motivation to comply with recommended interventions. The American Gastroenterological Association and other organizations recommend treatment with antiobesity medications along with lifestyle modifications for patients with obesity (BMI ≥ 30) and weight-related complications (BMI > 27). Recommended medications include phentermine-topiramate and bupropion-naltrexone (which may benefit those with binge-eating disorder), as well as injectable glucagon-like peptide receptor agonists (GLP-1 RAs) at the approved dosage for obesity management (semaglutide 2.4 mg weekly or liraglutide 3.0 mg daily). Orlistat is not recommended. Ongoing research on the potential benefit of GLP-1 RAs in management of binge eating offers additional support for a role in patients, like this one, with binge-eating disorder and obesity.

Artera, the Los Altos, California–based developer of tools to diagnose cancer, has launched the first artificial intelligence (AI) test to guide patients in making informed decisions between active surveillance and active treatment based on an analysis of digital pathology images.

Trevor Royce, MD, MPH, senior medical director of Artera, said the new version of the ArteraAI Prostate Test helps patients with low-risk (Grade Group 1/Gleason 6) to favorable intermediate-risk (Grade Group 2/Gleason 3+4) prostate cancer choose between treatment or active surveillance.

The test estimates how a patient’s cancer may progress and predicts the benefit of treatment for localized prostate cancer. 

“The prognostic performance of the test has now been validated in a diverse cohort of patients, including those who have undergone active surveillance, radiation therapy, or had a radical prostatectomy,” said Dr. Royce, a faculty member in radiation oncology at Wake Forest University School of Medicine in Winston-Salem, North Carolina. “The prognostic risk result reflects the patient’s prognosis regardless of the treatment path chosen.”

Dr. Royce said the new test predicts the risk for developing distant metastasis in 10 years. For the population considering active surveillance, it also can predict the likelihood their cancer will show more aggressive features. The test does not make a clinical recommendation, he added.

“Ultimately, that’s a very personal decision between the patient and their physician, and we view it as supporting that decision-making process,” he said.

The test is available in all states but New York and California, where the company is now, in discussions with regulators for approval, according to Dr. Royce. He said the company is in discussion with private insurers to set reimbursement and payment rates. In January 2024, Medicare set a payment rate of $700 for the AI test, which carries no out-of-pocket costs for patients. 

The first indication for the test was for localized prostate cancer, prognosticating the risk for distant metastases and death from prostate cancer. It can also predict if an individual will benefit from androgen deprivation therapy (ADT). Dr. Royce said up to 60% of patients with intermediate risk prostate cancer now can avoid ADT and its serious side effects, such as brain fog, weight gain, and reduction in muscle mass.

In March, the National Comprehensive Cancer Network, an alliance of 33 cancer centers included Artera as the first AI test in its Clinical Practice Guidelines in Oncology.

Dr. Royce said active surveillance is a new application of the test. The test was initially developed on a foundational study of almost 22,000 pathology slides from nearly 7000 patients published in npj Digital Medicine in 2022.

Todd Morgan, MD, chief of the Division of Urologic Oncology at the University of Michigan in Ann Arbor, and coauthor of the foundational study, said the AI test adds another layer of data to making clinical decisions for lower-risk patients.

“The technology is a big deal. The ability to use digital images to make accurate prognostic estimates is pretty remarkable, and this is the first test in any disease site to do this,” Dr. Morgan said. “Ultimately, this means tests may someday be performed by just sending images rather than sending actual tissue to an outside laboratory. Is the AI test dramatically more accurate than the genomic platforms? That’s TBD [to be determined].”

Dr. Royce said Artera is now working on a version of its test to inform men with higher-risk prostate cancer how long ADT should last and what the prognosis is for patients who have undergone prostatectomy based on their surgical specimen. The current test uses samples from the prostate biopsy, which are processed in a central lab. 

Dr. Royce said the company would like to eventually perform the test using digital images of pathology slides only.

Dr. Morgan reported no conflicts of interest.

In March, the National Comprehensive Cancer Network, an alliance of 33 cancer centers included Artera as the first AI test in its Clinical Practice Guidelines in Oncology.

Dr. Royce said active surveillance is a new application of the test. The test was initially developed on a foundational study of almost 22,000 pathology slides from nearly 7000 patients published in npj Digital Medicine in 2022.

Todd Morgan, MD, chief of the Division of Urologic Oncology at the University of Michigan in Ann Arbor, and coauthor of the foundational study, said the AI test adds another layer of data to making clinical decisions for lower-risk patients.

“The technology is a big deal. The ability to use digital images to make accurate prognostic estimates is pretty remarkable, and this is the first test in any disease site to do this,” Dr. Morgan said. “Ultimately, this means tests may someday be performed by just sending images rather than sending actual tissue to an outside laboratory. Is the AI test dramatically more accurate than the genomic platforms? That’s TBD [to be determined].”

Dr. Royce said Artera is now working on a version of its test to inform men with higher-risk prostate cancer how long ADT should last and what the prognosis is for patients who have undergone prostatectomy based on their surgical specimen. The current test uses samples from the prostate biopsy, which are processed in a central lab. 

Dr. Royce said the company would like to eventually perform the test using digital images of pathology slides only.

Dr. Morgan reported no conflicts of interest.

Artera, the Los Altos, California–based developer of tools to diagnose cancer, has launched the first artificial intelligence (AI) test to guide patients in making informed decisions between active surveillance and active treatment based on an analysis of digital pathology images.

Trevor Royce, MD, MPH, senior medical director of Artera, said the new version of the ArteraAI Prostate Test helps patients with low-risk (Grade Group 1/Gleason 6) to favorable intermediate-risk (Grade Group 2/Gleason 3+4) prostate cancer choose between treatment or active surveillance.

The test estimates how a patient’s cancer may progress and predicts the benefit of treatment for localized prostate cancer. 

“The prognostic performance of the test has now been validated in a diverse cohort of patients, including those who have undergone active surveillance, radiation therapy, or had a radical prostatectomy,” said Dr. Royce, a faculty member in radiation oncology at Wake Forest University School of Medicine in Winston-Salem, North Carolina. “The prognostic risk result reflects the patient’s prognosis regardless of the treatment path chosen.”

Dr. Royce said the new test predicts the risk for developing distant metastasis in 10 years. For the population considering active surveillance, it also can predict the likelihood their cancer will show more aggressive features. The test does not make a clinical recommendation, he added.

“Ultimately, that’s a very personal decision between the patient and their physician, and we view it as supporting that decision-making process,” he said.

The test is available in all states but New York and California, where the company is now, in discussions with regulators for approval, according to Dr. Royce. He said the company is in discussion with private insurers to set reimbursement and payment rates. In January 2024, Medicare set a payment rate of $700 for the AI test, which carries no out-of-pocket costs for patients. 

The first indication for the test was for localized prostate cancer, prognosticating the risk for distant metastases and death from prostate cancer. It can also predict if an individual will benefit from androgen deprivation therapy (ADT). Dr. Royce said up to 60% of patients with intermediate risk prostate cancer now can avoid ADT and its serious side effects, such as brain fog, weight gain, and reduction in muscle mass.

For years, electroconvulsive therapy (ECT) has been a lifesaving treatment for patients with treatment-resistant depression (TRD), yet exactly how it works has largely remained a mystery. Now researchers believe they have uncovered the underlying mechanisms behind its therapeutic effects — a discovery that may help clinicians better predict treatment response in individual patients and quell much of the fear and stigma associated with one of psychiatry’s most effective, yet misunderstood, treatments.

Two recent papers published in Translational Psychiatry have highlighted the significance of aperiodic neural activity. The first study showed this activity increased following ECT treatment. The second study expanded on these data by demonstrating a significant increase in aperiodic activity after patients received either ECT or magnetic seizure therapy (MST), which has a better side-effect profile than ECT but lower efficacy.

Aperiodic activity is “like the brain’s background noise, and for years scientists treated it that way and didn’t pay much attention to it,” first author Sydney E. Smith, a PhD candidate at the Voytek Lab in the Neuroscience Graduate Program at the University of California San Diego (UCSD), said in a press release.

However, aperiodic activity boosts inhibitory activity in the brain, effectively slowing it down,” the investigators noted.

In an interview with this news organization, Ms. Smith used a car analogy to explain the mechanism behind ECT. “ECT might be increasing the activity levels in the brain cells that help calm it down. It taps on the brakes that tend to malfunction in depression. By restoring the balance between the gas and the brakes in the brain, some of those depressive symptoms are alleviated,” she said.

Ms. Smith added her team’s research helps demystify one of the most effective yet stigmatized treatments for severe depression.

“Aperiodic activity as a physiologically interpretable EEG metric could be a really valuable new predictive indicator for treatment response,” she added.
 

Fear and Stigma

ECT is primarily used for TRD and is effective in up to 80% of patients, yet it remains one of the least prescribed treatments.

Although it’s been around for almost 90 years, fear and concern about its potential cognitive side effects have contributed to its poor uptake. It is estimated that less than 1% of patients with TRD receive ECT.

Smith noted that the 1970s movie One Flew Over the Cuckoo’s Nest still contributes to ECT’s stigma. In the film, actor Jack Nicholson’s character is forced to undergo ECT as a punishment.

It’s important for clinicians to acknowledge the stigma while advising patients that “the actual treatment doesn’t look anything like what’s in the movies,” noted Ms. Smith. Patients must give informed consent for the procedure, and it’s delivered with the lowest level of effective stimulation.

“So many steps are taken to consider comfort and efficacy for patients and to minimize how scary it can be,” she said.

ECT uses an electrical current to induce a seizure that spreads to deep subcortical structures. MST, which was developed as an alternative to ECT, uses a magnetic field to induce a more focal seizure primarily confined to the cortex.

Although MST has a better side-effect profile, experts noted it has remission rates of 30%-60% compared with ECT. Even one of MST’s inventors, Harold Sackeim, PhD, professor in the Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, is skeptical about its efficacy for TRD.

“I don’t think it works,” Dr. Sackeim, founding editor of Brain Stimulation: Basic, Translational, and Clinical Research in Neuromodulation, told this news organization.

In addition to being more expensive, MST produces a peak electrical intensity at one-tenth of what a typical ECT stimulus produces. “We’re limited by electrical engineering at this point with MST. That’s my view; others are more optimistic,” he said.
 

A Lifesaving Treatment

One of the reasons ECT isn’t more popular is because for many patients, it’s easier and more convenient to just take a pill, senior investigator Bradley Voytek, PhD, professor of cognitive science at UCSD, said in the release.

“However, in people for whom medications don’t work, [ECT] can be lifesaving. Understanding how it works will help us discover ways to increase the benefits while minimizing side effects,” he added.

In the first study, which included nine patients with major depressive disorder (MDD), EEG results showed an increase in aperiodic activity following ECT.

The investigators then wanted to test whether these findings could be replicated in a larger study. They retrospectively assessed two previous datasets — 1 of 22 patients with MDD who received ECT and 1 of 23 patients who received MST. After treatment, both groups showed increased aperiodic activity.

“Although not directly related to clinical efficacy in this dataset, increased aperiodic activity is linked to greater amounts of neural inhibition, which is suggestive of a potential shared neural mechanism of action across ECT and MST,” the investigators wrote.

The researchers noted that this increase in aperiodic activity is a more parsimonious explanation for observations of clinical slowing than delta band power or delta oscillations for both ECT and MST.”

So why is it important to know exactly how ECT works, and is there any clinical utility to these research findings?

“It’s important for clinicians to give a patient who has questions, a meaningful understanding of what the treatment is going to do, especially with something so scary and stigmatized. The ability to tell a patient why this treatment is working could provide a level of comfort that can assuage some of these fears,” Ms. Smith said.
 

A New Predictor of Response?

In addition, she noted that psychiatry is becoming more focused on predictive indicators for treatment.

“It’s asking: Are there any biological measures that can be used to predict whether someone is going to respond to a treatment or not?” said Ms. Smith.

“Aperiodic activity might be a valuable asset to add to that arsenal. Maybe we can better predict which patients might respond to ECT by using this as an additional biological indicator,” she added.

Smith noted that while more studies are needed, it’s exciting that some investigators are already starting to include aperiodic activity as a variable in their research analyses on a variety of topics, such as pharmacological intervention and transcranial magnetic stimulation.

“I don’t know exactly how much utility aperiodic activity is going to have in terms of being a great biological indicator, but I hope that the research will start to play out and reveal a little bit more,” she said.

Dr. Sackeim noted that ECT is one of the most misunderstood, controversial, and infrequently used treatments in psychiatry.

“But there’s also no doubt that when you look at ECT, it saves the lives of people with psychiatric illness. Period, full stop,” he said.

He added that although restarting a patient’s heart doesn’t seem to cause unease in the public, the idea of applying electricity to the brain under anesthesia in order to provoke a seizure for therapeutic purpose causes anxiety.

Still, the benefits and harms of a treatment are more important than how it looks, Sackeim said. “If it was only about how it looks, we’d never have surgery,” he added.
 

‘A Huge Success Story’

ECT was first introduced by Hungarian neuropsychiatrist László Meduna in 1935, and today clinicians “know where the current goes in the brain, at what dosage, and with what path you can get 70%, 80% fully remitted,” said Dr. Sackeim.

He noted that in a randomized study published in JAMA Psychiatry, investigators compared the outcomes of MST vs ECT for major depressive episodes in 73 patients. They reported that although depression symptom scores decreased for both treatments, there was “no significant difference” between the two in response or remission rates.

However, in an opinion letter the journal published in April, Dr. Sackeim and colleagues Mark S. George, MD, Medical University of South Carolina, and William V. McCall, MD, Augusta University, Augusta, Georgia, strongly questioned the findings.

At less than 30%, “the ECT remission rate after acute treatment was exceptionally low, limiting confidence in the validity and/or generalizability of the findings,” they wrote.

“It’s undoubtedly the case that either if you recruited a sample from whom the treatment may not be as efficacious or if there are issues in delivering them, then you may be finding equivalence” between ECT and MST, Dr. Sackeim said.

In addition, he noted that although there have been concerns about cognitive side effects with ECT, they have improved over the years. Sackeim reported that when he entered the field, the average time for a patient to remember their name or the day of the week was 6 hours after receiving unilateral ECT and 8 hours after bilateral ECT. “With modern methods, that’s now down to 10 minutes,” he said.

“The fundamental knowledge is that this treatment can be administered far softer than it ever was in the past. Impressions from the 50s and 60s and portrayed in movies have very little to do with modern practice and with the real effects of the treatment,” Dr. Sackeim said.

As for the new studies about aperiodic activity, the investigators are “essentially saying, ‘We have a better marker’ of the process. That way of thinking had in many ways been left behind in the run to study connectivity,” Dr. Sackeim said.

He noted that years ago, while he was with Columbia University, his team found that patients who had frontal inhibition were more likely to get well after ECT.

“And that’s essentially the same thing you’re hearing from the UCSD group. They’re saying that the aperiodic measure is hopefully of clearer physiological significance than simply delta [waves] in the EEG,” Dr. Sackeim said.

“The idea that inhibition was the key to its efficacy has been around. This is saying it’s a better measure of that, and that may be true. It’s certainly an interesting contribution,” he added.

Dr. Sackeim said the takeaway message for clinicians regarding ECT today is that it can be lifesaving but is still often only used as a last resort and reserved for those who have run out of options.

However, he said, ECT is “a huge success story: Maintaining its efficacy, reducing its side effects, getting an understanding as to what the physics of it are. We have some compelling stories about ECT, but even more so, we know what’s not true. And what’s not true are most of the assumptions people have about the treatment,” he concluded.

Ms. Smith and Dr. Voytek reported no relevant conflicts of interest. Dr. Sackeim reported holding patents in ECT technology and consulting with the MECTA Corporation and SigmaStim LLC and other neuromodulation companies.

As for the new studies about aperiodic activity, the investigators are “essentially saying, ‘We have a better marker’ of the process. That way of thinking had in many ways been left behind in the run to study connectivity,” Dr. Sackeim said.

He noted that years ago, while he was with Columbia University, his team found that patients who had frontal inhibition were more likely to get well after ECT.

“And that’s essentially the same thing you’re hearing from the UCSD group. They’re saying that the aperiodic measure is hopefully of clearer physiological significance than simply delta [waves] in the EEG,” Dr. Sackeim said.

“The idea that inhibition was the key to its efficacy has been around. This is saying it’s a better measure of that, and that may be true. It’s certainly an interesting contribution,” he added.

Dr. Sackeim said the takeaway message for clinicians regarding ECT today is that it can be lifesaving but is still often only used as a last resort and reserved for those who have run out of options.

However, he said, ECT is “a huge success story: Maintaining its efficacy, reducing its side effects, getting an understanding as to what the physics of it are. We have some compelling stories about ECT, but even more so, we know what’s not true. And what’s not true are most of the assumptions people have about the treatment,” he concluded.

Ms. Smith and Dr. Voytek reported no relevant conflicts of interest. Dr. Sackeim reported holding patents in ECT technology and consulting with the MECTA Corporation and SigmaStim LLC and other neuromodulation companies.

Experts are debating whether and how to define obesity, but clinicians’ attitudes and behavior toward patients with obesity don’t seem to be undergoing similar scrutiny.

“Despite scientific evidence to the contrary, the prevailing view in society is that obesity is a choice that can be reversed by voluntary decisions to eat less and exercise more,” a multidisciplinary group of 36 international experts wrote in a joint consensus statement for ending the stigma of obesity, published a few years ago in Nature Medicine. “These assumptions mislead public health policies, confuse messages in popular media, undermine access to evidence-based treatments, and compromise advances in research.”

These assumptions also affect how clinicians view and treat their patients.

A systematic review and meta-analysis from Australia using 27 different outcomes to assess weight bias found that “medical doctors, nurses, dietitians, psychologists, physiotherapists, occupational therapists, speech pathologists, podiatrists, and exercise physiologists hold implicit and/or explicit weight-biased attitudes toward people with obesity.”

Another recent systematic review, this one from Brazil, found that obesity bias affected both clinical decision-making and quality of care. Patients with obesity had fewer screening exams for cancer, less-frequent treatment intensification in the management of obesity, and fewer pelvic exams. The authors concluded that their findings “reveal the urgent necessity for reflection and development of strategies to mitigate the adverse impacts” of obesity bias.

“Weight is one of those things that gets judged because it can be seen,” Obesity Society Spokesperson Peminda Cabandugama, MD, of Cleveland Clinic, told this news organization. “People just look at someone with overweight and say, ‘That person needs to eat less and exercise more.’ ”
 

How Obesity Bias Manifests

The Obesity Action Coalition (OAC), a partner organization to the consensus statement, defines weight bias as “negative attitudes, beliefs, judgments, stereotypes, and discriminatory acts aimed at individuals simply because of their weight. It can be overt or subtle and occur in any setting, including employment, healthcare, education, mass media, and relationships with family and friends.”

The organization notes that weight bias takes many forms, including verbal, written, media, and online.

The consensus statement authors offer these definitions, which encompass the manifestations of obesity bias: Weight stigma refers to “social devaluation and denigration of individuals because of their excess body weight and can lead to negative attitudes, stereotypes, prejudice, and discrimination.” 

Weight discrimination refers to “overt forms of weight-based prejudice and unfair treatment (biased behaviors) toward individuals with overweight or obesity.” The authors noted that some public health efforts “openly embrace stigmatization of individuals with obesity based on the assumption that shame will motivate them to change behavior and achieve weight loss through a self-directed diet and increased physical exercise.”

The result: “Individuals with obesity face not only increased risk of serious medical complications but also a pervasive, resilient form of social stigma. Often perceived (without evidence) as lazy, gluttonous, lacking will power and self-discipline, individuals with overweight or obesity are vulnerable to stigma and discrimination in the workplace, education, healthcare settings, and society in general.”

“Obesity bias is so pervasive that the most common thing I hear when I ask a patient why they’re referred to me is ‘my doctor wants me to lose weight,’” Dr. Cabandugama said. “And the first thing I ask them is ‘what do you want to do?’ They come in because they’ve already been judged, and more often than not, in ways that come across as derogatory or punitive — like it’s their fault.”

 

Why It Persists

Experts say a big part of the problem is the lack of obesity education in medical school. A recent survey study found that medical schools are not prioritizing obesity in their curricula. Among 40 medical schools responding to the survey, only 10% said they believed their students were “very prepared” to manage patients with obesity, and one third had no obesity education program in place with no plans to develop one.

“Most healthcare providers do not get much meaningful education on obesity during medical school or postgraduate training, and many of their opinions may be influenced by the pervasive weight bias that exists in society,” affirmed Jaime Almandoz, MD, medical director of Weight Wellness Program and associate professor of internal medicine at UT Southwestern Medical Center in Dallas. “We need to prioritize updating education and certification curricula to reflect the current science.”

Small wonder that a recent comparison of explicit weight bias among US resident physicians from 49 medical schools across 16 clinical specialties found “problematic levels” of weight bias — eg, anti-fat blame, anti-fat dislike, and other negative attitudes toward patients — in all specialties. 
 

What to Do

To counteract the stigma, when working with patients who have overweight, “We need to be respectful of them, their bodies, and their health wishes,” Dr. Almandoz told this news organization. “Clinicians should always ask for permission to discuss their weight and frame weight or BMI in the context of health, not just an arbitrary number or goal.”

“Many people with obesity have had traumatic and stigmatizing experiences with well-intentioned healthcare providers,” he noted. “This can lead to the avoidance of routine healthcare and screenings and potential exacerbations and maladaptive health behaviors.”

“Be mindful of the environment that you and your office create for people with obesity,” he advised. “Consider getting additional education and information about weight bias.”

The OAC has resources on obesity bias, including steps clinicians can take to reduce the impact. These include, among others: Encouraging patients to share their experiences of stigma to help them feel less isolated in these experiences; helping them identify ways to effectively cope with stigma, such as using positive “self-talk” and obtaining social support from others; and encouraging participation in activities that they may have restricted due to feelings of shame about their weight.

Clinicians can also improve the physical and social environment of their practice by having bathrooms that are easily negotiated by heavier individuals, sturdy armless chairs in waiting rooms, offices with large exam tables, gowns and blood pressure cuffs in appropriate sizes, and “weight-friendly” reading materials rather than fashion magazines with thin supermodels.

Importantly, clinicians need to address the issue of weight bias within themselves, their medical staff, and colleagues, according to the OAC. To be effective and empathic with individuals affected by obesity “requires honest self-examination of one’s own attitudes and weight bias.”

Dr. Almandoz reported being a consultant/advisory board member for Novo Nordisk, Boehringer Ingelheim, and Eli Lilly and Company. Dr. Cabandugama reported no competing interests.

TOPLINE:

A systematic review and network meta-analysis found cranberry juice can help prevent urinary tract infections (UTIs).

METHODOLOGY:

• With an increasing prevalence of antimicrobial resistance and over 50% women reporting at least one episode of UTI each year, identifying evidence supporting possible nondrug interventions is necessary, according to the study researchers from Bond University, the University of Helsinki, and the University of Oxford.
• The primary study outcome was number of UTIs in each treatment or placebo group; the secondary outcomes were UTI symptoms such as increased bladder sensation, urgency, frequency, dysuria, and consumption of antimicrobial drugs.
• Studies analyzed included people of any age and gender at a risk for UTI.
• Researchers included 3091 participants from 18 randomized controlled trials and two nonrandomized controlled trials.

TAKEAWAY:

• Studies used one of the following interventions: Cranberry nonliquid products (tablet, capsule, or fruit), cranberry liquid, liquid other than cranberry, and no treatment.
• A total of 18 studies showed a 27% lower rate of UTIs with the consumption of cranberry juice than with placebo liquid (moderate certainty evidence) and a 54% lower rate of UTIs with the consumption of cranberry juice than with no treatment (very low certainty evidence).
• Based on a meta-analysis of six studies, antibiotic use was 49% lower with the consumption of cranberry juice than with placebo liquid and 59% lower than with no treatment.
• Cranberry compounds also were associated with a decrease in prevalence of UTI symptoms.

IN PRACTICE:

“The evidence supports the use of cranberry juice for the prevention of UTIs. While increased liquids benefit the rate of UTIs and reduce antibiotic use, and cranberry compounds benefit symptoms of infection, the combination of these, in cranberry juice, provides clear and significant clinical outcomes for the reduction in UTIs and antibiotic use and should be considered for the management of UTIs,” the authors wrote.

SOURCE:

The study was led by Christian Moro, PhD, faculty of health sciences and medicine at Bond University in Gold Coast, Australia, and was published online in European Urology Focus on July 18, 2024.

LIMITATIONS:

The authors noted that some planned findings such as the impact on antibiotic use were reduced due to limited studies. Some studies on cranberry tablets also provided education with the intervention, which could have affected UTI recurrence rates. Nearly all the 20 studies that were analyzed included mostly women; thus, comparisons between genders were not possible.

DISCLOSURES:

Dr. Moro reported no disclosures.

Jeffrey E. Janis, MD, is on a mission. The professor of plastic surgery, surgery, neurosurgery, and neurology at The Ohio State University Wexner Medical Center, Columbus, Ohio, wants to convince neurologists of the safety and efficacy of nerve decompression surgery for treatment-resistant headache. However, many neurologists remain unconvinced.

“Headache surgery is a viable alternative for complex patients who have failed medical management and who could benefit from this treatment approach. There’s 24 years of evidence behind this surgical technique across hundreds of different studies with different study designs,” Dr. Janis said. 

Yet this treatment approach — surgery on peripheral nerves rather than the brain or spinal cord — hasn’t garnered much support from neurologists. A scan of the agenda of topics at the recently held 2024 annual meeting of the American Headache Society showed few if any studies or presentations on this topic. And neurologists this news organization spoke to said they believe the surgery is experimental and unproven.

Experts do agree drugs don’t work for all patients with migraines. Up to 30% of patients don’t respond to the “laundry list of medications” available to treat the condition, said Dr. Janis.

Many patients have also tried, and failed, alternative treatment approaches such as massage, acupuncture, craniosacral therapy, transdermal patches, electrical stimulation, cryoablation, neurostimulation, and radiofrequency ablation.

If nothing else works, is surgery for headaches the answer?
 

Long-Held Theory

The idea that pinched, irritated, or compressed peripheral nerves can trigger migraine attacks has been around for nearly 25 years. Studies suggest that in addition to migraine, nerve compression can lead to other headache conditions, including occipital neuralgia, supraorbital neuralgia , and post-traumatic headaches.

This has led to the development of surgical techniques to deactivate various compression trigger sites — what Dr. Janis calls “pinch points” — which could involve muscles, bone, fascia, blood vessels, or scar tissue from prior trauma or surgery.

The procedure is predominantly performed by plastic surgeons, but to a lesser degree by neurosurgeons and ear, nose, and throat specialists.

Target nerves in surgical interventions include those in the frontal region of the head above the eye, temporal region, neck region, and nasal region. Affected areas are usually identified either through patient self-reports or by using a nerve block agent such as lidocaine or Botox at specific points, Dr. Janis noted. If pain subsides after an injection, that location is marked as a target.

One of the barriers to referring complicated patients for surgery is that neurologists evaluating migraine treatments “speak a different language” than surgeons performing the procedure, said Dr. Janis.

Neurologists tend to focus on reduction in monthly migraine days (MMD), while surgeons typically use the Migraine Headache Index that incorporates the frequency, intensity, and duration of migraine attacks.

“Rather than try to convince somebody to speak a different language, we thought, why don’t we just learn their language so we can build bridges and take down barriers,” said Dr. Janis, coauthor of a systematic review and meta-analysis published online recently in Plastic and Reconstructive Surgery.

Investigators examined 19 studies in the review, including five randomized controlled trials (RCTs), published from January 2020 to September 2023, with a total of 1603 participants who were mostly female and ranged in age from 9 to 72 years. Study follow-ups extended from 6 to 38 months. All but three studies were carried out in the United States, and six different compression sites were addressed during surgery.

Investigators found that across studies and by a number of measures, migraine frequency and severity improved after surgery.

Monthly migraine days decreased by 36%-92% and the number of overall migraine attacks per month dropped 25%-87.5%. Patients also reported decreases in attack duration of 41%-75% and intensity of 28%-82% across studies.

“Even using the neurologist-standard language of monthly migraine days, this surgery works,” said Dr. Janis. “Now this is documented both in the surgical literature and the nonsurgical literature.”

The most common complications were ecchymosis, hair loss or thinning, itching, dryness, and rhinorrhea, all of which Dr. Janis described as “fairly minor.” Major complications such as intraoperative bleeding and wound dehiscence were rare, occurring in 1% or less of participants.
 

‘One And Done?’

These surgeries are usually done on an outpatient basis and generally offer long-term results, Dr. Janis said.

“The idea is one and done,” he said. “The literature around this type of surgery says that whatever type of effect you get at 1 year is likely to be permanent.”

The American Society of Plastic Surgeons agrees. A 2018 position paper developed by experts and commissioned by the society reports that the intervention is safe and effective for appropriate patients, based on a comprehensive literature search and review of a large body of peer-reviewed scientific evidence.

“There is substantial, extensively replicated clinical data that demonstrates a significant reduction in [migraine headache] symptoms and frequency (even complete elimination of headache pain) following trigger site surgery,” the authors noted.

Pamela Blake, MD, a neurologist, board-certified headache specialist, and medical director at the Headache Center of River Oaks, Houston, is a proponent of what she said can be “lifesaving” headache surgery.

“If a doctor told you that you can either treat this problem with medications that you’ll need to take for the rest of your life or you can have a surgical procedure as an outpatient that has extremely low risk and has, in my experience, a 75% chance of reducing or eliminating your pain, you probably would be interested in surgery,” she said.
 

Continued Skepticism

However, other neurologists and clinicians appear doubtful about this intervention, including Hans-Christoph Diener, MD, PhD, professor of neurology and director, Essen Headache Centre, University of Duisburg-Essen in Germany.

During a debate on the topic a decade ago at the International Headache Congress, Dr. Diener argued that, as migraine is a complex multigene-related disorder of the brain, it doesn’t make sense that surgery would affect the epigenetics of 22 different genes.

Recently, he said that his views have not changed.

The topic remains controversial, and some neurologists are uncomfortable even openly discussing the procedure. Two clinicians who previously commented on this article later asked not to be included.

One neurologist, who asked to remain anonymous, said that Dr. Janis’s review article is “merely a review collecting 19 studies over the previous 10-plus years.”

Other limitations cited by this neurologist are the lack of consistency in procedures among the various studies and the inclusion of only four RCTs, the most recent of which was published 8 years ago, suggesting “the study was probably done closer to 9 or 10 years ago,” the neurologist said.

Dr. Blake suggested some neurologists’ reluctance could be due to limited background on the procedure, which she said isn’t widely discussed at headache meetings and is covered mostly in plastic surgery journals, not neurology literature. Access to surgery is further limited by a lack of specialists who perform the procedure and inconsistent insurance coverage.

A closer collaboration between neurologists and surgeons who perform the procedure could benefit patients, Dr. Blake noted.

“The headache doctor’s role is to identify who’s a candidate for surgery, who meets the criteria for nerve compression, and then follow that patient postoperatively, managing their medications, although usually we get them off their medications,” she added.

From Dr. Janis’s perspective, things are starting to change.

“I’m definitely seeing a greater comfort level among neurologists who are understanding where this sits in the algorithm for treatment, especially for complicated patients,” he said.

Dr. Janis receives royalties from Thieme and Springer Publishing. Dr. Blake reported no relevant conflicts. Dr. Diener received research support from the German Research Council; serves on the editorial boards of Cephalalgia, Lancet Neurology, and Drugs; and has received honoraria for participation in clinical trials, contribution to advisory boards, or oral presentations from AbbVie, Lilly, Lundbeck, Novartis, Pfizer, Teva, Weber & Weber, and WebMD.

Jeffrey E. Janis, MD, is on a mission. The professor of plastic surgery, surgery, neurosurgery, and neurology at The Ohio State University Wexner Medical Center, Columbus, Ohio, wants to convince neurologists of the safety and efficacy of nerve decompression surgery for treatment-resistant headache. However, many neurologists remain unconvinced.

“Headache surgery is a viable alternative for complex patients who have failed medical management and who could benefit from this treatment approach. There’s 24 years of evidence behind this surgical technique across hundreds of different studies with different study designs,” Dr. Janis said. 

Yet this treatment approach — surgery on peripheral nerves rather than the brain or spinal cord — hasn’t garnered much support from neurologists. A scan of the agenda of topics at the recently held 2024 annual meeting of the American Headache Society showed few if any studies or presentations on this topic. And neurologists this news organization spoke to said they believe the surgery is experimental and unproven.

Experts do agree drugs don’t work for all patients with migraines. Up to 30% of patients don’t respond to the “laundry list of medications” available to treat the condition, said Dr. Janis.

Many patients have also tried, and failed, alternative treatment approaches such as massage, acupuncture, craniosacral therapy, transdermal patches, electrical stimulation, cryoablation, neurostimulation, and radiofrequency ablation.

If nothing else works, is surgery for headaches the answer?
 

Long-Held Theory

The idea that pinched, irritated, or compressed peripheral nerves can trigger migraine attacks has been around for nearly 25 years. Studies suggest that in addition to migraine, nerve compression can lead to other headache conditions, including occipital neuralgia, supraorbital neuralgia , and post-traumatic headaches.

This has led to the development of surgical techniques to deactivate various compression trigger sites — what Dr. Janis calls “pinch points” — which could involve muscles, bone, fascia, blood vessels, or scar tissue from prior trauma or surgery.

The procedure is predominantly performed by plastic surgeons, but to a lesser degree by neurosurgeons and ear, nose, and throat specialists.

Target nerves in surgical interventions include those in the frontal region of the head above the eye, temporal region, neck region, and nasal region. Affected areas are usually identified either through patient self-reports or by using a nerve block agent such as lidocaine or Botox at specific points, Dr. Janis noted. If pain subsides after an injection, that location is marked as a target.

One of the barriers to referring complicated patients for surgery is that neurologists evaluating migraine treatments “speak a different language” than surgeons performing the procedure, said Dr. Janis.

Neurologists tend to focus on reduction in monthly migraine days (MMD), while surgeons typically use the Migraine Headache Index that incorporates the frequency, intensity, and duration of migraine attacks.

“Rather than try to convince somebody to speak a different language, we thought, why don’t we just learn their language so we can build bridges and take down barriers,” said Dr. Janis, coauthor of a systematic review and meta-analysis published online recently in Plastic and Reconstructive Surgery.

Investigators examined 19 studies in the review, including five randomized controlled trials (RCTs), published from January 2020 to September 2023, with a total of 1603 participants who were mostly female and ranged in age from 9 to 72 years. Study follow-ups extended from 6 to 38 months. All but three studies were carried out in the United States, and six different compression sites were addressed during surgery.

Investigators found that across studies and by a number of measures, migraine frequency and severity improved after surgery.

Monthly migraine days decreased by 36%-92% and the number of overall migraine attacks per month dropped 25%-87.5%. Patients also reported decreases in attack duration of 41%-75% and intensity of 28%-82% across studies.

“Even using the neurologist-standard language of monthly migraine days, this surgery works,” said Dr. Janis. “Now this is documented both in the surgical literature and the nonsurgical literature.”

The most common complications were ecchymosis, hair loss or thinning, itching, dryness, and rhinorrhea, all of which Dr. Janis described as “fairly minor.” Major complications such as intraoperative bleeding and wound dehiscence were rare, occurring in 1% or less of participants.
 

‘One And Done?’

These surgeries are usually done on an outpatient basis and generally offer long-term results, Dr. Janis said.

“The idea is one and done,” he said. “The literature around this type of surgery says that whatever type of effect you get at 1 year is likely to be permanent.”

The American Society of Plastic Surgeons agrees. A 2018 position paper developed by experts and commissioned by the society reports that the intervention is safe and effective for appropriate patients, based on a comprehensive literature search and review of a large body of peer-reviewed scientific evidence.

“There is substantial, extensively replicated clinical data that demonstrates a significant reduction in [migraine headache] symptoms and frequency (even complete elimination of headache pain) following trigger site surgery,” the authors noted.

Pamela Blake, MD, a neurologist, board-certified headache specialist, and medical director at the Headache Center of River Oaks, Houston, is a proponent of what she said can be “lifesaving” headache surgery.

“If a doctor told you that you can either treat this problem with medications that you’ll need to take for the rest of your life or you can have a surgical procedure as an outpatient that has extremely low risk and has, in my experience, a 75% chance of reducing or eliminating your pain, you probably would be interested in surgery,” she said.
 

Continued Skepticism

However, other neurologists and clinicians appear doubtful about this intervention, including Hans-Christoph Diener, MD, PhD, professor of neurology and director, Essen Headache Centre, University of Duisburg-Essen in Germany.

During a debate on the topic a decade ago at the International Headache Congress, Dr. Diener argued that, as migraine is a complex multigene-related disorder of the brain, it doesn’t make sense that surgery would affect the epigenetics of 22 different genes.

Recently, he said that his views have not changed.

The topic remains controversial, and some neurologists are uncomfortable even openly discussing the procedure. Two clinicians who previously commented on this article later asked not to be included.

One neurologist, who asked to remain anonymous, said that Dr. Janis’s review article is “merely a review collecting 19 studies over the previous 10-plus years.”

Other limitations cited by this neurologist are the lack of consistency in procedures among the various studies and the inclusion of only four RCTs, the most recent of which was published 8 years ago, suggesting “the study was probably done closer to 9 or 10 years ago,” the neurologist said.

Skin grafting is a surgical technique used to cover skin defects resulting from the removal of skin tumors, ulcers, or burn injuries.^1-3 Complications can occur at both donor and recipient sites and may include bleeding, hematoma/seroma formation, postoperative pain, infection, scarring, paresthesia, skin pigmentation, graft contracture, and graft failure.^1,2,4,5 The development of epidermal tumors is not commonly reported among the complications of skin grafting; however, cases of epidermal tumor development on skin graft donor sites during the postoperative period have been reported.^6-12

We performed a systematic review of the literature for cases of epidermal tumor development on skin graft donor sites in patients undergoing autologous skin graft surgery. We present the clinical characteristics of these cases and discuss the nature of these tumors.

Methods

Search Strategy and Study Selection—A literature search was conducted by 2 independent researchers (Z.P. and V.P.) for articles published before December 2022 in the following databases: MEDLINE/PubMed, Web of Science, Scopus, Cochrane Library, OpenGrey, Google Scholar, and WorldCat. Search terms included all possible combinations of the following: keratoacanthoma, molluscum sebaceum, basal cell carcinoma, squamous cell carcinoma, acanthoma, wart, Merkel cell carcinoma, verruca, Bowen disease, keratosis, skin cancer, cutaneous cancer, skin neoplasia, cutaneous neoplasia, and skin tumor. The literature search terms were selected based on the World Health Organization classification of skin tumors.¹³ Manual bibliography checks were performed on all eligible search results for possible relevant studies. Discrepancies were resolved through discussion and, if needed, mediation by a third researcher (N.C.). To be included, a study had to report a case(s) of epidermal tumor(s) that was confirmed by histopathology and arose on a graft donor site in a patient receiving autologous skin grafts for any reason. No language, geographic, or report date restrictions were set.

Data Extraction, Quality Assessment, and Statistical Analysis—We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.¹⁴ Two independent researchers (Z.P. and V.P.) retrieved the data from the included studies. We have used the terms case and patient interchangeably, and 1 month was measured as 4 weeks for simplicity. Disagreements were resolved by discussion and mediation by a third researcher (N.C.). The quality of the included studies was assessed by 2 researchers (M.P. and V.P.) using the tool proposed by Murad et al.¹⁵

We used descriptive statistical analysis to analyze clinical characteristics of the included cases. We performed separate descriptive analyses based on the most frequently reported types of epidermal tumors and compared the differences between different groups using the Mann-Whitney U test, χ2 test, and Fisher exact test. The level of significance was set at P<.05. All statistical analyses were conducted using SPSS (version 29).

Results

Literature Search and Characteristics of Included Studies—The initial literature search identified 1378 studies, which were screened based on title and abstract. After removing duplicate and irrelevant studies and evaluating the full text of eligible studies, 31 studies (4 case series and 27 case reports) were included in the systematic review (Figure).^6-12,16-39 Quality assessment of the included studies is presented in Table 1.

Clinical Characteristics of Included Patients—Our systematic review included 36 patients with a mean age of 63 years and a male to female ratio of 2:1. The 2 most common causes for skin grafting were burn wounds and surgical excision of skin tumors. Most grafts were harvested from the thighs. The development of a solitary lesion on the donor area was reported in two-thirds of the patients, while more than 1 lesion developed in the remaining one-third of patients. The median time to tumor development was 6.5 weeks. In most cases, a split-thickness skin graft was used.

Cutaneous squamous cell carcinomas (CSCCs) were found in 23 patients, with well-differentiated CSCCs in 19 of these cases. Additionally, keratoacanthomas (KAs) were found in 10 patients. The majority of patients underwent surgical excision of the tumor. The median follow-up time was 12 months, during which recurrences were noted in a small percentage of cases. Clinical characteristics of included patients are presented in Table 2.

Comment

Reasons for Tumor Development on Skin Graft Donor Sites—The etiology behind epidermal tumor development on graft donor sites is unclear. According to one theory, iatrogenic contamination of the donor site during the removal of a primary epidermal tumor could be responsible. However, contemporary surgical procedures dictate the use of different sets of instruments for separate surgical sites. Moreover, this theory cannot explain the occurrence of epidermal tumors on donor sites in patients who have undergone skin grafting for the repair of burn wounds.³⁷

Another theory suggests that hematogenous and/or lymphatic spread can occur from the site of the primary epidermal tumor to the donor site, which has increased vascularization.^16,37 However, this theory also fails to provide an explanation for the development of epidermal tumors in patients who receive skin grafts for burn wounds.

A third theory states that the microenvironment of the donor site is key to tumor development. The donor site undergoes acute inflammation due to the trauma from harvesting the skin graft. According to this theory, acute inflammation could promote neoplastic growth and thus explain the development of epidermal tumors on the donor site.^8,26 However, the relationship between acute inflammation and carcinogenesis remains unclear. What is known to date is that the development of CSCC has been documented primarily in chronically inflamed tissues, whereas the development of KA—a variant of CSCC with distinctive and more benign clinical characteristics—can be expected in the setting of acute trauma-related inflammation.^13,40,41

Based on our systematic review, we propose that well-differentiated CSCC on graft donor sites might actually be misdiagnosed KA, given that the histopathologic differential diagnosis between CSCC and KA is extremely challenging.⁴² This hypothesis could explain the development of well-differentiated CSCC and KA on graft donor sites.

Conclusion

Development of CSCC and KA on graft donor sites can be listed among the postoperative complications of autologous skin grafting. Patients and physicians should be aware of this potential complication, and donor sites should be monitored for the occurrence of epidermal tumors.

What is known to date is that the development of CSCC has been documented primarily in chronically inflamed tissues, whereas the development of KA—a variant of CSCC with distinctive and more benign clinical characteristics—can be expected in the setting of acute trauma-related inflammation.^13,40,41

Based on our systematic review, we propose that well-differentiated CSCC on graft donor sites might actually be misdiagnosed KA, given that the histopathologic differential diagnosis between CSCC and KA is extremely challenging.⁴² This hypothesis could explain the development of well-differentiated CSCC and KA on graft donor sites.

Conclusion

Development of CSCC and KA on graft donor sites can be listed among the postoperative complications of autologous skin grafting. Patients and physicians should be aware of this potential complication, and donor sites should be monitored for the occurrence of epidermal tumors.

WASHINGTON — Immunoglobulin E (IgE) and eosinophils appeared to be reliable biomarkers of type 2 inflammation in chronic pruritus of unknown origin (CPUO) and predictors of a positive response to immunomodulatory therapies, Shawn G. Kwatra, MD, said at the ElderDerm conference on dermatology in older patients hosted by the GW School of Medicine & Health Sciences.

“We found a few years ago that eosinophils seem to differentiate this group, and now we’re finding that IgE and CBC [complete blood count] differential can help you get a little better sense of who has an immune-driven itch vs something more neuropathic,” said Dr. Kwatra, professor and chair of dermatology at the University of Maryland, Baltimore, who founded and directed the Johns Hopkins Itch Center before coming to the University of Maryland in 2023. Not all patients with immune-driven itch will have these biomarkers, “but it’s a helpful tool,” he said.

Dr. Kwatra

CPUO is the term that is increasingly being used, he said, to describe intense, chronic pruritus without primary skin lesions or rashes and without any known systemic cause. It becomes more common as people get older and is sometimes debilitating. The initial evaluation should be kept “simple and straightforward,” he advised, with heightened concern for underlying malignancy in those who present with an itch of less than 12 months’ duration.
 

Biologics, JAK Inhibitors: Case Reports, Ongoing Research 

Research conducted by Dr. Kwatra and Jaya Manjunath, a fourth-year medical student at The George Washington University, Washington, documented higher levels of Th2-associated cytokines and inflammatory markers in patients with CPUO who had elevated IgE or eosinophil levels, or both than in patients with itch who had low IgE and eosinophil levels. The patients with higher levels also had a greater response to off-label treatment with immunomodulatory therapy.

“Multiple Th2-related inflammatory markers, like IL [interleukin]-5 and eotaxin-3, were reduced after dupilumab” in patients who responded to the therapy, said Ms. Manjunath, who co-presented the meeting session on chronic itch with Dr. Kwatra. Other changes in the plasma cytokine profile included a reduction in the serum level of thymus and activation-regulated chemokine, which is a biomarker for atopic dermatitis. The research is under review for publication.

Meanwhile, a phase 3 trial (LIBERTY-CPUO-CHIC) of dupilumab for CPUO is currently underway, Dr. Kwatra noted. Investigators are randomizing patients with severe pruritus (Worst Itch Numeric Rating Scale [WI-NRS] ≥ 7) to dupilumab or placebo for 12 or 24 weeks.

In one of several cases shared by Dr. Kwatra and Ms. Manjunath, a 71-year-old Black woman with a 6-month history of generalized itch (WI-NRS = 10) and a history of type 2 diabetes, hypertension, and chronic kidney disease was found to have elevated eosinophil levels and a negative malignancy workup. Previous therapies included antihistamines and topical steroids. She was started on a 600-mg loading dose of subcutaneous dupilumab followed by 300 mg every 14 days. At the 2-month follow-up, her WI-NRS score was 0.

Because “dupilumab is off label right now for this form of itch, oftentimes our first line is methotrexate,” Dr. Kwatra said. Patients “can have a good response with this therapeutic.”

He also described the case of a 72-year-old Black woman with total body itch for 2 years (WI-NRS = 10) and a history of seasonal allergies, thyroid disease, and hypertension. Previous therapies included prednisone, antihistamines, topical steroids, and gabapentin. The patient was found to have high IgE (447 kU/L) and eosinophil levels (4.9%), was started on methotrexate, and had an itch score of 0 at the 8-month follow-up.

JAK inhibitors may also have a role in the management of CPUO. A phase 2 nonrandomized controlled trial of abrocitinib for adults with prurigo nodularis (PN) or CPUO, recently published in JAMA Dermatology, showed itch scores decreased by 53.7% in the CPUO group (and 78.3% in the PN group) after 12 weeks of treatment with oral abrocitinib 200 mg daily. Patients had significant improvements in quality of life and no serious adverse events, said Dr. Kwatra, the lead author of the paper.

One of these patients was a 73-year-old White man who had experienced total body itch for 1.5 years (predominantly affecting his upper extremities; WI-NRS = 10) and a history of ascending aortic aneurysm, hypertension, and hyperlipidemia. Previous failed therapies included dupilumab (> 6 months), topical steroids, tacrolimus, and antihistamines. Labs showed elevated IgE (456 kU/L) and eosinophil levels (11.7%). After 12 weeks of treatment with abrocitinib, the WI-NRS decreased to 2.
 

PD-1 Inhibitors As a Trigger

Chronic pruritus caused by the anticancer PD-1 inhibitors is becoming more common as the utilization of these immune checkpoint inhibitors increases, Dr. Kwatra noted. “You don’t see much in the skin, but [these patients have] very high IgE and eosinophils,” he said. “We’ve been seeing more reports recently of utilizing agents that target type 2 inflammation off label for PD-1 inhibitor–related skin manifestations.”

One such patient with PD-1 inhibitor–induced pruritus was a 65-year-old White man with metastatic melanoma who reported a 6-month history of itching that began 3 weeks after the start of treatment with the PD-1 inhibitor pembrolizumab. His WI-NRS score was 10 despite treatment with topical steroids and antihistamines. He had a history of psoriasis. Labs showed elevated IgE (1350 kU/L) and eosinophil levels (4.5%). At a 4-month follow-up after treatment with off-label dupilumab (a 600-mg subcutaneous loading dose followed by 300 mg every 14 days), his WI-NRS score was 0.

In a paper recently published in JAAD International, Dr. Kwatra, Ms. Manjunath, and coinvestigators reported on a series of 15 patients who developed chronic pruritus following an immune stimulus exposure, including immunotherapy and vaccination (2024 Apr 7:16:97-102. doi: 10.1016/j.jdin.2024.03.022). Most immunotherapy-treated patients experienced pruritus during treatment or after 21-60 days of receiving treatment, and the patients with vaccine-stimulated pruritus (after Tdap and messenger RNA COVID-19 vaccination) developed pruritus within a week of vaccination.

In addition to the elevated levels of IgE and eosinophils, plasma cytokine analysis showed elevated levels of IL-5, thymic stromal lymphopoietin, and other Th2-related cytokines and inflammatory markers in patients with immune-stimulated pruritus compared with healthy controls, Ms. Manjunath said at the meeting.

When a Malignancy Workup Becomes Important

The initial part of any diagnostic workup for CPUO should include CBC with differential, liver function tests, renal function tests, and thyroid function testing, said Kwatra, referring to a diagnostic algorithm he developed, which was published as part of a CME review in the Journal of the American Academy of Dermatology in 2022.

Then, as indicated by risk factors in the history and physical, one could order other tests such as HIV serology, hepatitis B/C serologies, bullous pemphigoid testing, chest x-rays, evaluation for gammopathies, stool examination for ova and parasites, or heavy metal testing. “Do you do everything at once? We like to keep it straightforward,” Dr. Kwatra said. “Depending on the patient’s risk factors, you could order more or less.”

A malignancy workup should be strongly considered in patients whose itch duration is less than 12 months — and especially if the duration is less than 3 months — with an emphasis on cancers more frequently associated with itch: Hematologic and hepatobiliary cancers. This is “when concern should be heightened ... when there should be a lower threshold for workup,” he said.

The 12-month recommendation stems from a Danish cohort study published in 2014 that demonstrated a twofold increased incidence of cancer among patients with pruritus in the first 3 months after the diagnosis of pruritus. The 1-year absolute cancer risk was 1.63%.

Other risk factors for underlying malignancy or malignancy development in patients with CPUO include age older than 60 years, male sex, liver disease, and current or prior smoking, according to another study, noted Dr. Kwatra.

Dr. Kwatra disclosed that he is an advisory board member/consultant for Pfizer, Regeneron, Sanofi, and other companies and an investigator for Galderma, Incyte, Pfizer, and Sanofi. Manjunath served as the codirector of the ElderDerm conference.

Patients experiencing memory problems often come to neurologist David Jones, MD, for second opinions. They repeat questions and sometimes misplace items. Their primary care clinician has suggested they may have Alzheimer’s disease or something else.

In many cases, Dr. Jones, a neurologist with Mayo Clinic in Rochester, Minnesota, performs a series of investigations and finds the patient instead has a different type of neurodegenerative syndrome, one that progresses slowly, seems limited chiefly to loss of memory, and which tests show affects only the limbic system.

The news of diagnosis can be reassuring to patients.

“Memory problems are not always Alzheimer’s disease,” Dr. Jones said. “It’s important to broaden the differential diagnosis and seek diagnostic clarity and precision for patients who experience problems with brain functioning later in life.”

Dr. Jones and colleagues recently published clinical criteria for what they call limbic-predominant amnestic neurodegenerative syndrome (LANS).

Various underlying etiologies are known to cause degeneration of the limbic system, the most frequent being a buildup of deposits of the TAR DNA-binding protein 43 (TDP-43) protein referred to as limbic-predominant, age-related TDP-43 encephalopathy neuropathological change (LATE-NC). LATE-NC first involves the amygdala, followed by the hippocampus, and then the middle frontal gyrus, and is found in about 40% of autopsied brains in people over age of 85 years.

By contrast, amnestic syndromes originating from neocortical degeneration are largely caused by neuropathological changes from Alzheimer’s disease and often present with non-memory features.
 

Criteria for LANS

Broken down into core, standard, and advanced features

Core clinical features:

The patient must present with a slow, amnestic, predominant neurodegenerative syndrome — an insidious onset with gradual progression over 2 or more years — without another condition that better accounts for the clinical deficits.

Standard supportive features:

1. Older age at evaluation.

• Most patients are at least the age of 75 years. Older age increases the likelihood that the amnestic syndrome is caused by degeneration of the limbic system.

2. Mild clinical syndrome.

• A diagnosis of mild cognitive impairment or mild amnestic dementia (ie, a score of ≤ 4 on the Clinical Dementia Rating Sum of Boxes [CDR-SB]) at the first visit.

3. Hippocampal atrophy out of proportion to syndrome severity.

• Hippocampal volume was smaller than expected on MRI, compared with the CDR-SB score.

4. Mildly impaired semantic memory.

Advanced supportive features:

1.Limbic hypometabolism and absence of neocortical degenerative pattern on fludeoxyglucose-18-PET imaging.

2. Low likelihood of significant neocortical tau pathology.


Dr. Jones and colleagues also classified a degree of certainty for LANS to use when making a diagnosis. Those with the highest likelihood meet all core, standard, and advanced features.

Patients with a high likelihood of having LANS meet core features, at least three standard features and one advanced feature; or meet core features, at least two standard features as well as two advanced features. Those with a moderate likelihood meet core features and at least three standard features or meet core features and at least two standard features and one advanced feature. Those with a low likelihood of LANS meet core features and two or fewer standard features.

To develop these criteria, the group screened 218 autopsied patients participating in databases for the Mayo Clinic Study of Aging and the multicenter Alzheimer’s Disease Neuroimaging Initiative. They conducted neuropathological assessments, reviewed MRI and PET scans of the brains, and studied fluid biomarkers from samples of cerebrospinal fluid.

In LANS, the neocortex exhibits normal function, Dr. Jones said. High-level language functions, visual spatial functions, and executive function are preserved, and the disease stays mild for many years. LANS is highly associated with LATE, for which no biomarkers are yet available.

The National Institute on Aging in May 2023 held a workshop on LATE, and a consensus group was formed to publish criteria to help with the diagnosis. Many LANS criteria likely will be in that publication as well, Dr. Jones said.

Several steps lay ahead to improve the definition of LANS, the authors wrote, including conducting prospective studies and developing clinical tools that are sensitive and specific to its cognitive features. The development of in vivo diagnostic markers of TDP-43 pathology is needed to embed LANS into a disease state driven by LATE-NC, according to Dr. Jones’ group. Because LANS is newly defined, clinical trials are needed to determine the best treatments.
 

Heterogeneous Dementia

“We are increasingly recognizing that the syndrome of dementia in older adults is heterogeneous,” said Sudha Seshadri, MD, DM, a behavioral neurologist and founding director of the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases at the University of Texas Health Science Center at San Antonio.

LANS “is something that needs to be diagnosed early but also needs to be worked up in a nuanced manner, with assessment of the pattern of cognitive deficits, the pattern of brain shrinkage on MRI, and also how the disease progresses over, say, a year,” said Dr. Seshadri. “We need to have both some primary care physicians and geriatricians who are comfortable doing this kind of nuanced advising and others who may refer patients to behavioral neurologists, geriatricians, or psychiatrists who have that kind of expertise.”

About 10% of people presenting to dementia clinics potentially could fit the LANS definition, Dr. Seshadri said. Dr. Seshadri was not a coauthor of the classification article but sees patients in the clinic who fit this description.

“It may be that as we start more freely giving the diagnosis of a possible LANS, the proportion of people will go up,” Dr. Seshadri said.

Primary care physicians can use a variety of assessments to help diagnose dementias, she said. These include the Montreal Cognitive Assessment (MoCA), which takes about 10 minutes to administer, or an MRI to determine the level of hippocampal atrophy. Blood tests for p-tau 217 and other plasma tests can stratify risk and guide referrals to a neurologist. Clinicians also should look for reversible causes of memory complaints, such as deficiencies in vitamin B12, folate, or the thyroid hormone.

“There aren’t enough behavioral neurologists around to work up every single person who has memory problems,” Dr. Seshadri said. “We really need to partner on educating and learning from our primary care partners as to what challenges they face, advocating for them to be able to address that, and then sharing what we know, because what we know is an evolving thing.”

Other tools primary care clinicians can use in the initial evaluation of dementia include the General Practitioner Assessment of Cognition and the Mini-Cog, as part of annual Medicare wellness visits or in response to patient or caregiver concerns about memory, said Allison Kaplan, MD, a family physician at Desert Grove Family Medical in Gilbert, Arizona, who coauthored a point-of-care guide for the American Academy of Family Physicians. Each of these tests takes just 3-4 minutes to administer.

If a patient has a positive result on the Mini-Cog or similar test, they should return for further dementia evaluation using the MoCA, Mini-Mental State Examination, or Saint Louis University Mental Status examination, she said. Physicians also can order brain imaging and lab work, as Dr. Seshadri noted. Dementias often accompany some type of cardiovascular disease, which should be managed.

Even if a patient or family member doesn’t express concern about memory, physicians can look for certain signs during medical visits.

“Patients will keep asking the same question, or you notice they’re having difficulty taking care of themselves, especially independent activities of daily living, which could clue you in to a dementia diagnosis,” she said.

Patients experiencing memory problems often come to neurologist David Jones, MD, for second opinions. They repeat questions and sometimes misplace items. Their primary care clinician has suggested they may have Alzheimer’s disease or something else.

In many cases, Dr. Jones, a neurologist with Mayo Clinic in Rochester, Minnesota, performs a series of investigations and finds the patient instead has a different type of neurodegenerative syndrome, one that progresses slowly, seems limited chiefly to loss of memory, and which tests show affects only the limbic system.

The news of diagnosis can be reassuring to patients.

“Memory problems are not always Alzheimer’s disease,” Dr. Jones said. “It’s important to broaden the differential diagnosis and seek diagnostic clarity and precision for patients who experience problems with brain functioning later in life.”

Dr. Jones and colleagues recently published clinical criteria for what they call limbic-predominant amnestic neurodegenerative syndrome (LANS).

Various underlying etiologies are known to cause degeneration of the limbic system, the most frequent being a buildup of deposits of the TAR DNA-binding protein 43 (TDP-43) protein referred to as limbic-predominant, age-related TDP-43 encephalopathy neuropathological change (LATE-NC). LATE-NC first involves the amygdala, followed by the hippocampus, and then the middle frontal gyrus, and is found in about 40% of autopsied brains in people over age of 85 years.

By contrast, amnestic syndromes originating from neocortical degeneration are largely caused by neuropathological changes from Alzheimer’s disease and often present with non-memory features.
 

Criteria for LANS

Broken down into core, standard, and advanced features

Core clinical features:

The patient must present with a slow, amnestic, predominant neurodegenerative syndrome — an insidious onset with gradual progression over 2 or more years — without another condition that better accounts for the clinical deficits.

Standard supportive features:

1. Older age at evaluation.

• Most patients are at least the age of 75 years. Older age increases the likelihood that the amnestic syndrome is caused by degeneration of the limbic system.

2. Mild clinical syndrome.

• A diagnosis of mild cognitive impairment or mild amnestic dementia (ie, a score of ≤ 4 on the Clinical Dementia Rating Sum of Boxes [CDR-SB]) at the first visit.

3. Hippocampal atrophy out of proportion to syndrome severity.

• Hippocampal volume was smaller than expected on MRI, compared with the CDR-SB score.

4. Mildly impaired semantic memory.

Advanced supportive features:

1.Limbic hypometabolism and absence of neocortical degenerative pattern on fludeoxyglucose-18-PET imaging.

2. Low likelihood of significant neocortical tau pathology.


Dr. Jones and colleagues also classified a degree of certainty for LANS to use when making a diagnosis. Those with the highest likelihood meet all core, standard, and advanced features.

Patients with a high likelihood of having LANS meet core features, at least three standard features and one advanced feature; or meet core features, at least two standard features as well as two advanced features. Those with a moderate likelihood meet core features and at least three standard features or meet core features and at least two standard features and one advanced feature. Those with a low likelihood of LANS meet core features and two or fewer standard features.

To develop these criteria, the group screened 218 autopsied patients participating in databases for the Mayo Clinic Study of Aging and the multicenter Alzheimer’s Disease Neuroimaging Initiative. They conducted neuropathological assessments, reviewed MRI and PET scans of the brains, and studied fluid biomarkers from samples of cerebrospinal fluid.

In LANS, the neocortex exhibits normal function, Dr. Jones said. High-level language functions, visual spatial functions, and executive function are preserved, and the disease stays mild for many years. LANS is highly associated with LATE, for which no biomarkers are yet available.

The National Institute on Aging in May 2023 held a workshop on LATE, and a consensus group was formed to publish criteria to help with the diagnosis. Many LANS criteria likely will be in that publication as well, Dr. Jones said.

Several steps lay ahead to improve the definition of LANS, the authors wrote, including conducting prospective studies and developing clinical tools that are sensitive and specific to its cognitive features. The development of in vivo diagnostic markers of TDP-43 pathology is needed to embed LANS into a disease state driven by LATE-NC, according to Dr. Jones’ group. Because LANS is newly defined, clinical trials are needed to determine the best treatments.
 

Heterogeneous Dementia

“We are increasingly recognizing that the syndrome of dementia in older adults is heterogeneous,” said Sudha Seshadri, MD, DM, a behavioral neurologist and founding director of the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases at the University of Texas Health Science Center at San Antonio.

LANS “is something that needs to be diagnosed early but also needs to be worked up in a nuanced manner, with assessment of the pattern of cognitive deficits, the pattern of brain shrinkage on MRI, and also how the disease progresses over, say, a year,” said Dr. Seshadri. “We need to have both some primary care physicians and geriatricians who are comfortable doing this kind of nuanced advising and others who may refer patients to behavioral neurologists, geriatricians, or psychiatrists who have that kind of expertise.”

About 10% of people presenting to dementia clinics potentially could fit the LANS definition, Dr. Seshadri said. Dr. Seshadri was not a coauthor of the classification article but sees patients in the clinic who fit this description.

“It may be that as we start more freely giving the diagnosis of a possible LANS, the proportion of people will go up,” Dr. Seshadri said.

Primary care physicians can use a variety of assessments to help diagnose dementias, she said. These include the Montreal Cognitive Assessment (MoCA), which takes about 10 minutes to administer, or an MRI to determine the level of hippocampal atrophy. Blood tests for p-tau 217 and other plasma tests can stratify risk and guide referrals to a neurologist. Clinicians also should look for reversible causes of memory complaints, such as deficiencies in vitamin B12, folate, or the thyroid hormone.
