Clinician Reviews

Patients with psoriatic disease have significantly higher risks of myocardial infarction, stroke, and cardiovascular mortality than does the general population, yet research consistently paints what dermatologist Joel M. Gelfand, MD, calls an “abysmal” picture: Only a minority of patients with psoriatic disease know about their increased risks, only a minority of dermatologists and rheumatologists screen for cardiovascular risk factors like lipid levels and blood pressure, and only a minority of patients diagnosed with hyperlipidemia are adequately treated with statin therapy.

In the literature and at medical meetings, Dr. Gelfand and others who have studied cardiovascular disease (CVD) comorbidity and physician practices have been urging dermatologists and rheumatologists to play a more consistent and active role in primary cardiovascular prevention for patients with psoriatic disease, who are up to 50% more likely than patients without it to develop CVD and who tend to have atherosclerosis at earlier ages.

According to the 2019 joint American Academy of Dermatology (AAD)–National Psoriasis Foundation (NPF) guidelines for managing psoriasis “with awareness and attention to comorbidities,” this means not only ensuring that all patients with psoriasis receive standard CV risk assessment (screening for hypertension, diabetes, and hyperlipidemia), but also recognizing that patients who are candidates for systemic therapy or phototherapy — or who have psoriasis involving > 10% of body surface area — may benefit from earlier and more frequent screening.

CV risk and premature mortality rises with the severity of skin disease, and patients with psoriatic arthritis (PsA) are believed to have risk levels similar to patients with moderate-severe psoriasis, cardiologist Michael S. Garshick, MD, director of the cardio-rheumatology program at New York University Langone Health, said in an interview.

In many cases, dermatologists and rheumatologists may be the primary providers for patients with psoriatic disease. So, “the question is, how can the dermatologist or rheumatologist use their interactions as a touchpoint to improve the patient’s well-being?” Dr. Barbieri said in an interview.

For the dermatologist, educating patients about the higher CVD risk fits well into conversations about “how there may be inflammation inside the body as well as in the skin,” he said. “Talk about cardiovascular risk just as you talk about PsA risk.” Both specialists, he added, can incorporate blood pressure readings and look for opportunities to measure lipid levels and hemoglobin A1c (HbA1c). These labs can easily be integrated into a biologic work-up.

“The hard part — and this needs to be individualized — is how do you want to handle [abnormal readings]? Do you want to take on a lot of the ownership and calculate [10-year CVD] risk scores and then counsel patients accordingly?” Dr. Barbieri said. “Or do you want to try to refer, and encourage them to work with their PCP? There a high-touch version and a low-touch version of how you can turn screening into action, into a care plan.”


 

Beyond traditional risk elevation, the primary care hand-off

Rheumatologists “in general may be more apt to screen for cardiovascular disease” as a result of their internal medicine residency training, and “we’re generally more comfortable prescribing ... if we need to,” said Alexis R. Ogdie, MD, a rheumatologist at the Hospital of the University of Pennsylvania, Philadelphia, and director of the Penn Psoriatic Arthritis Clinic.

Referral to a preventive cardiologist for management of abnormal lab results or ongoing monitoring and prevention is ideal, but when hand-offs to primary care physicians are made — the more common scenario — education is important. “A common problem is that there is underrecognition of the cardiovascular risk being elevated in our patients,” she said, above and beyond risk posed by traditional risk factors such as dyslipidemia, hypertension, metabolic syndrome, and obesity, all of which have been shown to occur more frequently in patients with psoriatic disease than in the general population.

‘Patients trust us’

Dr. Gelfand has been at the forefront of research on psoriasis and heart disease. A study he coauthored in 2006, for instance, documented an independent risk of MI, with adjusted relative risks of 1.29 and 3.10 for a 30-year-old patient with mild or severe disease, respectively, and higher risks for a 60-year-old. In 2010, he and coinvestigators found that severe psoriasis was an independent risk factor for CV mortality (HR, 1.57) after adjusting for age, sex, smoking, diabetes, hypertension, and hyperlipidemia.

Today, along with Dr. Barbieri, Dr. Ogdie, and others, he is studying the feasibility and efficacy of a proposed national, “centralized care coordinator” model of care whereby dermatologists and rheumatologists would educate the patient, order lipid and HbA1c measurements as medically appropriate, and then refer patients as needed to a care coordinator. The care coordinator would calculate a 10-year CVD risk score and counsel the patient on possible next steps.

In a pilot study of 85 patients at four sites, 92% of patients followed through on their physician’s recommendations to have labs drawn, and 86% indicated the model was acceptable and feasible. A total of 27% of patients had “newly identified, previously undiagnosed, elevated cardiovascular disease risk,” and exploratory effectiveness results indicated a successful reduction in predicted CVD risk in patients who started statins, Dr. Gelfand reported at the NPF meeting.

With funding from the NPF, a larger, single-arm, pragmatic “CP3” trial (NCT05908240) is enrolling 525 patients with psoriasis at 10-20 academic and nonacademic dermatology sites across the United States to further test the model. The primary endpoint will be the change in LDL cholesterol measured at 6 months among people with a 10-year risk ≥5%. Secondary endpoints will cover improvement in disease severity and quality of life, behavior modification, patient experience, and other issues.

“We have only 10-15 minutes [with patients] ... a care coordinator who is empathetic and understanding and [informed] could make a big difference,” Dr. Gelfand said at the NPF meeting. If findings are positive, the model would be tested in rheumatology sites as well. The hope, he said, is that the NPF would be able to fund an in-house care coordinator(s) for the long-term.

Notably, a patient survey conducted as part of exploratory research leading up to the care coordinator project showed that patients trust their dermatologist or rheumatologist for CVD education and screening. Among 160 patients with psoriasis and 162 patients with PsA, 76% and 90% agreed that “I would like it if my dermatologist/rheumatologist educated me about my risk of heart disease,” and 60% and 75%, respectively, agree that “it would be convenient for me to have my cholesterol checked by my dermatologist/rheumatologist.”

“Patients trust us,” Dr. Gelfand said at the NPF meeting. “And the pilot study shows us that patients are motivated.”
 

Taking an individualized, holistic, longitudinal approach

“Sometimes you do have to triage bit,” Dr. Gelfand said in an interview. “For a young person with normal body weight who doesn’t smoke and has mild psoriasis, one could just educate and advise that they see their primary care physician” for monitoring.

“But for the same patient who is obese, maybe smokes, and doesn’t have a primary care physician, I’d order labs,” he said. “You don’t want a patient walking out the door with an [undiagnosed] LDL of 160 or hypertension.”

Age is also an important consideration, as excess CVD risk associated with autoimmune diseases like psoriasis rises with age, Dr. Gelfand said during a seminar on psoriasis and PsA held at NYU Langone in December. For a young person, typically, “I need to focus on education and lifestyle … setting them on a healthy lifestyle trajectory,” he said. “Once they get to 40, from 40 to 75 or so, that’s a sweet spot for medical intervention to lower cardiovascular risk.”

Even at older ages, however, lipid management is not the be-all and end-all, he said in the interview. “We have to be holistic.”

One advantage of having highly successful therapies for psoriasis, and to a lesser extent PsA, is the time that becomes available during follow-up visits — once disease is under control — to “focus on other things,” he said. Waiting until disease is under control to discuss diet, exercise, or smoking, for instance, makes sense anyway, he said. “You don’t want to overwhelm patients with too much to do at once.”

Indeed, said dermatologist Robert E. Kalb, MD, of the Buffalo Medical Group in Buffalo, NY, “patients have an open mind [about discussing cardiovascular disease risk], but it is not high on their radar. Most of them just want to get their skin clear.” (Dr. Kalb participated in the care coordinator pilot study, and said in an interview that since its completion, he has been more routinely ordering relevant labs.)

Rheumatologists are less fortunate with highly successful therapies, but “over the continuum of care, we do have time in office visits” to discuss issues like smoking, exercise, and lifestyle, Dr. Ogdie said. “I think of each of those pieces as part of our job.”

In the future, as researchers learn more about the impact of psoriasis and PsA treatments on CVD risk, it may be possible to tailor treatments or to prescribe treatments knowing that the therapies could reduce risk. Observational and epidemiologic data suggest that tumor necrosis factor-alpha inhibitor therapy over 3 years reduces the risk of MI, and that patients whose psoriasis is treated have reduced aortic inflammation, improved myocardial strain, and reduced coronary plaque burden, Dr. Garshick said at the NPF meeting.

“But when we look at the randomized controlled trials, they’re actually inconclusive that targeting inflammation in psoriatic disease reduces surrogates of cardiovascular disease,” he said. Dr. Garshick’s own research focuses on platelet and endothelial biology in psoriasis.

Dr. Barbieri reported he had no relevant disclosures. Dr. Garshick reported consulting fees from Bristol-Myers Squibb, Kiniksa, Horizon Therapeutics, and Agepha. Dr. Ogdie reported financial relationships with AbbVie, Amgen, Bristol-Myers Squibb, Celgene, Eli Lilly, Gilead, GlaxoSmithKline, Janssen, Novartis, Pfizer, Takeda, and UCB. Dr. Gelfand reported serving as a consultant for AbbVie, Artax, Bristol-Myers Squibb, GlaxoSmithKline, and other companies.

The Diagnosis: Lichen Sclerosus

Histopathology revealed a thin epidermis with homogenization of the upper dermal collagen. By contrast, the lower dermis was sclerotic with patchy chronic dermal infiltrate (Figure). Ultimately, the patient’s clinical presentation and histopathologic findings led to a diagnosis of lichen sclerosus (LS).

Lichen sclerosus is a rare chronic inflammatory skin condition that typically is characterized by porcelainwhite atrophic plaques on the skin, most often involving the external female genitalia including the vulva and perianal area.¹ It is thought to be underdiagnosed and underreported.² Extragenital manifestations may occur, though some cases are characterized by concomitant genital involvement.^3,4 Our patient presented with palmoplantar distribution of plaques without genitalia involvement. Approximately 6% to 10% of patients with extragenital LS do not have genital involvement at the time of diagnosis.^3,5 Furthermore, LS involving the palms and soles is exceedingly rare.² Although extragenital LS may be asymptomatic, patients can experience debilitating pruritus; bullae with hemorrhage and erosion; plaque thickening with repeated excoriations; and painful fissuring, especially if lesions are in areas that are susceptible to friction or tension.^3,6 New lesions on previously unaffected skin also may develop secondary to trauma through the Koebner phenomenon.^1,6

Histologically, LS is characterized by epidermal hyperkeratosis accompanied by follicular plugging, epidermal atrophy with flattened rete ridges, vacuolization of the basal epidermis, marked edema in the superficial dermis (in early lesions) or homogenized collagen in the upper dermis (in established lesions), and a lymphohistiocytic infiltrate beneath the homogenized collagen. Although the pathogenesis of LS is unclear, purported etiologic factors from studies in genital disease include immune dysfunction, genetic predisposition, infection, and trauma.⁶ Lichen sclerosus is associated strongly with autoimmune diseases including alopecia areata, vitiligo, autoimmune thyroiditis, diabetes mellitus, and pernicious anemia, indicating its potential multifactorial etiology and linkage to T-lymphocyte dysfunction.¹ Early LS lesions often appear as flat-topped and slightly scaly, hypopigmented, white or mildly erythematous, polygonal papules that coalesce to form larger plaques with peripheral erythema. With time, the inflammation subsides, and lesions become porcelain-white with varying degrees of palpable sclerosis, resembling thin paperlike wrinkles indicative of epidermal atrophy.⁶

The differential diagnosis of LS includes lichen planus (LP), morphea, discoid lupus erythematosus (DLE), and vitiligo.³ Lesions of LP commonly are described as flat-topped, polygonal, pink-purple papules localized mostly along the volar wrists, shins, presacral area, and hands.⁷ Lichen planus is considered to be more pruritic³ than LS and can be further distinguished by biopsy through identifying a well-formed granular layer and numerous cytoid bodies. Unlike LS, LP is not characterized by basement membrane thickening or epidermal atrophy.⁸

Skin lesions seen in morphea may resemble the classic atrophic white lesions of extragenital LS; however, it is unclear if the appearance of LS-like lesions with morphea is a simultaneous occurrence of 2 separate disorders or the development of clinical findings resembling LS in lesions of morphea.⁶ Furthermore, morphea involves deep inflammation and sclerosis of the dermis that may extend into subcutaneous fat without follicular plugging of the epidermis.^3,9 In contrast, LS primarily affects the epidermis and dermis with the presence of epidermal follicular plugging.⁶

Lesions seen in DLE are characterized as well-defined, annular, erythematous patches and plaques followed by follicular hyperkeratosis with adherent scaling. Upon removal of the scale, follicle-sized keratotic spikes (carpet tacks) are present.¹⁰ Scaling of lesions and the carpet tack sign were absent in our patient. In addition, DLE typically reveals surrounding pigmentation and scarring over plaques,3 which were not observed in our patient.

Vitiligo commonly is associated with extragenital LS. As with LS, vitiligo can be explained by mechanisms of immune checkpoint inhibitor–induced cytotoxicity as well as perforin and granzyme-B expression.¹¹ Although vitiligo resembles the late hypopigmented lesions of extragenital LS, there are no plaques or surface changes, and a larger, more generalized area of the skin typically is involved.³

Histopathology revealed a thin epidermis with homogenization of the upper dermal collagen. By contrast, the lower dermis was sclerotic with patchy chronic dermal infiltrate (Figure). Ultimately, the patient’s clinical presentation and histopathologic findings led to a diagnosis of lichen sclerosus (LS).

Lichen sclerosus is a rare chronic inflammatory skin condition that typically is characterized by porcelainwhite atrophic plaques on the skin, most often involving the external female genitalia including the vulva and perianal area.¹ It is thought to be underdiagnosed and underreported.² Extragenital manifestations may occur, though some cases are characterized by concomitant genital involvement.^3,4 Our patient presented with palmoplantar distribution of plaques without genitalia involvement. Approximately 6% to 10% of patients with extragenital LS do not have genital involvement at the time of diagnosis.^3,5 Furthermore, LS involving the palms and soles is exceedingly rare.² Although extragenital LS may be asymptomatic, patients can experience debilitating pruritus; bullae with hemorrhage and erosion; plaque thickening with repeated excoriations; and painful fissuring, especially if lesions are in areas that are susceptible to friction or tension.^3,6 New lesions on previously unaffected skin also may develop secondary to trauma through the Koebner phenomenon.^1,6

Histologically, LS is characterized by epidermal hyperkeratosis accompanied by follicular plugging, epidermal atrophy with flattened rete ridges, vacuolization of the basal epidermis, marked edema in the superficial dermis (in early lesions) or homogenized collagen in the upper dermis (in established lesions), and a lymphohistiocytic infiltrate beneath the homogenized collagen. Although the pathogenesis of LS is unclear, purported etiologic factors from studies in genital disease include immune dysfunction, genetic predisposition, infection, and trauma.⁶ Lichen sclerosus is associated strongly with autoimmune diseases including alopecia areata, vitiligo, autoimmune thyroiditis, diabetes mellitus, and pernicious anemia, indicating its potential multifactorial etiology and linkage to T-lymphocyte dysfunction.¹ Early LS lesions often appear as flat-topped and slightly scaly, hypopigmented, white or mildly erythematous, polygonal papules that coalesce to form larger plaques with peripheral erythema. With time, the inflammation subsides, and lesions become porcelain-white with varying degrees of palpable sclerosis, resembling thin paperlike wrinkles indicative of epidermal atrophy.⁶

The differential diagnosis of LS includes lichen planus (LP), morphea, discoid lupus erythematosus (DLE), and vitiligo.³ Lesions of LP commonly are described as flat-topped, polygonal, pink-purple papules localized mostly along the volar wrists, shins, presacral area, and hands.⁷ Lichen planus is considered to be more pruritic³ than LS and can be further distinguished by biopsy through identifying a well-formed granular layer and numerous cytoid bodies. Unlike LS, LP is not characterized by basement membrane thickening or epidermal atrophy.⁸

Skin lesions seen in morphea may resemble the classic atrophic white lesions of extragenital LS; however, it is unclear if the appearance of LS-like lesions with morphea is a simultaneous occurrence of 2 separate disorders or the development of clinical findings resembling LS in lesions of morphea.⁶ Furthermore, morphea involves deep inflammation and sclerosis of the dermis that may extend into subcutaneous fat without follicular plugging of the epidermis.^3,9 In contrast, LS primarily affects the epidermis and dermis with the presence of epidermal follicular plugging.⁶

Lesions seen in DLE are characterized as well-defined, annular, erythematous patches and plaques followed by follicular hyperkeratosis with adherent scaling. Upon removal of the scale, follicle-sized keratotic spikes (carpet tacks) are present.¹⁰ Scaling of lesions and the carpet tack sign were absent in our patient. In addition, DLE typically reveals surrounding pigmentation and scarring over plaques,3 which were not observed in our patient.

Vitiligo commonly is associated with extragenital LS.

The relationship between alcohol consumption and cardiovascular disease (CVD) may be more nuanced than previously thought, with evidence emerging that alcohol use may both increase and decrease the risk for CVD.

The answer may depend on the presence of circulating metabolites of alcohol, some of which may be beneficial while others may be harmful, new research suggests. 

“We adopted an association analysis, looking at 60 metabolites produced during or after alcohol has been metabolized, to see whether those metabolites can link alcohol consumption with CVD,” senior author Jiantao Ma, PhD, MBBS, assistant professor, Division of Nutrition Epidemiology and Data Science, Friedman School, Tufts University, Boston, Massachusetts, said in an interview.

“We found that the relationship is quite complex, with some metabolites showing protective effects against CVD and others showing harmful effects,” said Dr. Ma. “This opens the door for future research because we think that these molecules can help [us] understand the mechanism of the relationship between alcohol and CVD.”

The study was published online in BMC Medicine.

J-Shaped Relationship?

Previous research has painted a confusing picture of the relationship between alcohol consumption and CVD. For example, some studies have suggested that moderate levels of drinking may be hazardous to cardiac health, while others have pointed to potential cardioprotective effects.

Nevertheless, “according to the latest ACC/AHA guidelines regarding alcohol consumption and its relationship to CVD, there is no level of alcohol use that is deemed safe and considered acceptable,” Saurabh Sharma, MD, program director, Internal Medicine Residency Program, and clinical assistant professor of cardiology, Geisinger Commonwealth School of Medicine, Scranton, Pennsylvania, said in an interview.

Older observational data suggested a “J-shaped” relationship between alcohol consumption and cardiovascular risk, such that a low to moderate amount might reduce risk, while higher amounts increase it, said Dr. Sharma, a member of the American College of Cardiology (ACC) Prevention of Cardiovascular Diseases Council.

“But it’s essential to note that these findings were based on observational studies. No randomized controlled trials have provided conclusive evidence supporting the idea that moderate alcohol consumption actively reduces cardiovascular risk,” he said.

The current study is also observational, but it shines a somewhat different spotlight on the subject by examining alcohol consumption–related metabolites, said Dr. Ma — that is, small molecules that are the intermediates or end-products of metabolism in many cellular processes. 

Some recent research “shows that alcohol may be harmful or at least has no beneficial effect in CVD prevention,” he said. “Our motivation was to analyze the association using metabolites, genetics, and epigenetics, because we think that these molecules may help us understand some of the mechanisms that underlie the relationship between alcohol consumption and CVD, and partially answer the question of whether alcohol may be harmful or helpful.” 

Caution Warranted

Although some previous studies have looked at metabolites, most analyzed alcohol consumption measured at a single time point, “which may not represent habitual or long-term alcohol consumption,” the researchers note. 

The team used data derived from 2458 Framingham Heart Study Offspring participants (mean age, 56 ± 9.3 years at the fifth examination; 52% female), calculating the cumulative average alcohol consumption from total intake of beer, wine, and liquor over an average 20-year period. Most participants were overweight, close to one fifth were current smokers, and 636 developed CVD over the study period.

Participants were assessed every 4-8 years, with metabolites measured during the fifth examination. 

Linear models were used to investigate the association of alcohol consumption with 211 plasma metabolites, adjusting for a variety of potential confounders, including age, sex, batch, smoking, diet, physical activity, body mass index, and familial relationship.

Sixty metabolites associated with cumulative average alcohol consumption were identified (P < .00024), after adjustment for confounders. Of these, 40 displayed positive associations with the cumulative average alcohol consumption, with the most significant metabolite being cholesteryl palmitoleate (CE16:1), a plasma cholesteryl ester involved with cholesterol metabolism.

One gram per day of higher alcohol consumption was associated with a higher-level CE16:1 in the blood (b = .023). Several other phosphatidylcholine metabolites were also positively associated with alcohol consumption.

On the other hand, 20 metabolites were negatively associated with alcohol consumption, with triacylglycerol 54:4 (TAG 54:4) displaying the most significant association (b = –.017).

The alcoholic beverages were not equal when it came to association with metabolites: 19 metabolites were significantly associated with the cumulative average consumption of beer, 30 with wine, and 32 with liquor. Seven were significantly associated with the cumulative consumption of all three types of drinks.

The researchers conducted survival analysis that identified 10 alcohol-associated metabolites associated with differential CVD risks, after adjusting for confounders. They also built two alcohol consumption–weighted metabolite scores using these 10 metabolites. After adjustment for confounders including CVD risk factors, the two scores had “comparable but opposite” associations with incident CVD, HR 1.11 (95% CI, 1.02-1.21) vs 0.88 (0.78-0.98; both P values = .02). 

“We found that seven metabolites were harmful, while three were beneficial, “ Dr. Ma reported. 

Dr. Ma cautioned that association “doesn’t represent causation.” On the basis of the findings, however, “we can hypothesize that if you drink a moderate amount of alcohol, you can either increase or decrease your risk of CVD.”

For people with cardiac conditions, “it would be [wise to be] cautious in recommending alcohol consumption,” he said. “For people without cardiac conditions, I would follow the recommendations of the AHA. If people don’t already drink alcohol, we don’t recommend that you start drinking it; and if you already drink, we’d recommend keeping it minimal.”

He cautioned that this is “only one study and we need more research if we are to generate a clearer message to the patient.” At present, perhaps the best message to patients is “to be cautious and warn them that there are potentially harmful effects,” he said.

Mendelian Randomization?

Dr. Sharma, who was not involved in the study, emphasized that it’s “crucial” to recognize that the study “does not alter the established understanding that any level of alcohol consumption poses harm to the heart,” and that “any amount of alcohol consumption has the potential to elevate triglyceride levels, thereby contributing to the increased risk of cardiovascular complications.”

Previously reported cardioprotective benefits “are likely influenced by confounding factors, such as lifestyle and sociodemographic elements,” he speculated. 

He noted that observational studies “encounter challenges in disentangling the influence of factors like obesity, lack of exercise, and tobacco use” as well as reverse causality.

“To overcome these limitations, Mendelian randomization emerges as a robust method,” he suggested. “This approach utilizes measured genetic variations with known functions to investigate the causal effect of a modifiable exposure on disease within the framework of observational studies.”

Notably, certain studies using this approach, including one by Larsson and colleagues, and another by Biddinger and associates, “have provided valuable insights by establishing a clear and causal relationship between alcohol consumption and CVD,” he said. 

The study was funded by the National Institute of Health’s National Institute on Alcohol Abuse and Alcoholism. Data collection in the Framingham Heart Study was supported by the National Heart, Lung, and Blood Institute. Dr. Ma and coauthors and Dr. Sharma disclosed no relevant financial relationships.

The Food and Drug Administration has approved a foam formulation of roflumilast, a phosphodiesterase-4 (PDE-4) inhibitor, for the treatment of seborrheic dermatitis, the manufacturer announced in a press release.

The 0.3% foam, marketed as Zoryve, applied once-daily, is indicated for patients aged 9 years and older with seborrheic dermatitis, and can be used anywhere on the body, including areas with hair, with no limits on duration of use, according to the company, Arcutis. A 0.3% cream formulation of roflumilast was previously approved by the FDA for the topical treatment of plaque psoriasis in patients aged 6 years and older.

Approval was based on data from the phase 3 STRATUM trial and an accompanying phase 2 study known as Trial 203. These studies included a total of 683 adults and youth aged 9 years and older with seborrheic dermatitis. Participants were randomized to roflumilast or a placebo.

At 8 weeks, 79.5 % of patients on roflumilast met the primary efficacy endpoint of Investigator Global Assessment (IGA) scores of 0 or 1 (clear or almost clear) compared with 58.0% of patients on placebo (P < .001); the results were similar in the phase 2 Trial 203 (73.1% vs. 40.8%, respectively; P < .001). Overall, more than 50% of the patients on roflumilast achieved a clear score.

Patients in the roflumilast group also showed significant improvement in all secondary endpoints, including itching, scaling, and erythema, according to the company.

In the STRATUM study, 62.8% of roflumilast-treated patients and 40.6% of placebo patients achieved a 4-point or more reduction in itch based on the Worst Itch Numerical Rating Score (P =.0001), and 28% of roflumilast-treated patients reported significant itch improvement within the first 48 hours of use, compared with 13% of placebo patients (P = .0024).

Over a treatment period of up to 1 year, no treatment-related severe adverse events were reported in the phase 2 and 3 studies. The incidence of treatment emergent adverse events was similar between the treatment and placebo groups, and the most common adverse events (occurring in 1% of more of patients) across both studies were nasopharyngitis (1.5%), nausea (1.3%), and headache (1.1%).

Roflumilast foam is scheduled to be available by the end of January 2024, according to the company. The product is for topical use only, and contraindicated for individuals with severe liver impairment.

The incidence of treatment emergent adverse events was similar between the treatment and placebo groups, and the most common adverse events (occurring in 1% of more of patients) across both studies were nasopharyngitis (1.5%), nausea (1.3%), and headache (1.1%).

Roflumilast foam is scheduled to be available by the end of January 2024, according to the company. The product is for topical use only, and contraindicated for individuals with severe liver impairment.

The Food and Drug Administration has approved a foam formulation of roflumilast, a phosphodiesterase-4 (PDE-4) inhibitor, for the treatment of seborrheic dermatitis, the manufacturer announced in a press release.

The 0.3% foam, marketed as Zoryve, applied once-daily, is indicated for patients aged 9 years and older with seborrheic dermatitis, and can be used anywhere on the body, including areas with hair, with no limits on duration of use, according to the company, Arcutis. A 0.3% cream formulation of roflumilast was previously approved by the FDA for the topical treatment of plaque psoriasis in patients aged 6 years and older.

Approval was based on data from the phase 3 STRATUM trial and an accompanying phase 2 study known as Trial 203. These studies included a total of 683 adults and youth aged 9 years and older with seborrheic dermatitis. Participants were randomized to roflumilast or a placebo.

At 8 weeks, 79.5 % of patients on roflumilast met the primary efficacy endpoint of Investigator Global Assessment (IGA) scores of 0 or 1 (clear or almost clear) compared with 58.0% of patients on placebo (P < .001); the results were similar in the phase 2 Trial 203 (73.1% vs. 40.8%, respectively; P < .001). Overall, more than 50% of the patients on roflumilast achieved a clear score.

Patients in the roflumilast group also showed significant improvement in all secondary endpoints, including itching, scaling, and erythema, according to the company.

In the STRATUM study, 62.8% of roflumilast-treated patients and 40.6% of placebo patients achieved a 4-point or more reduction in itch based on the Worst Itch Numerical Rating Score (P =.0001), and 28% of roflumilast-treated patients reported significant itch improvement within the first 48 hours of use, compared with 13% of placebo patients (P = .0024).

Bass-heavy rock music applied directly to the abdomen of diabetic mice implanted with music-sensitive insulin-releasing cells attenuates postprandial glycemic excursions and restores normoglycemia, reveals a series of experiments.

The research was published in The Lancet Diabetes & Endocrinology.

After developing a cell line in which music-sensitive calcium channels triggered the release of insulin-containing vesicles, the researchers conducted a series of studies identifying the optimal frequency, pitch, and volume of sounds for triggering release.

After settling on low-bass heavy popular music, they tested their system on mice with type 1 diabetes that had the insulin-releasing cells implanted in their abdomen. Applying the music directly at 60 dB led to near wild-type levels of insulin in the blood within 15 minutes.

“With only 4 hours required for a full refill, [the system] can provide several therapeutic doses a day,” says Martin Fussenegger, PhD, professor of biotechnology and bioengineering, Department of Biosystems Science and Engineering, ETH Zurich, Basel, Switzerland, and colleagues.

“This would match the typical needs of people with type 2 diabetes consuming three meals a day, and for whom administration of prandial insulin is an established treatment option, as they do not have capability for early postprandial insulin secretion from preformed insulin.”

As the system requires nothing more than portable battery-powered commercially available loudspeakers, the multiple daily dosing of biopharmaceuticals becomes “straightforward in the absence of medical infrastructure or staff, simply by having the patient listen to the prescribed music.”

It therefore “could be an interesting option for cell-based therapies, especially where the need for frequent dosing raises compliance issues.”

It is a “very exciting piece of work, no doubt,” said Anandwardhan A. Hardikar, PhD, group leader, Diabetes and Islet Biology Group, Translational Health Research Institute, Western Sydney University, Penrith NSW, Australia.

He pointed out that the concept of using music to drive gene expression “is something we’ve known for the last 20 years,” but bringing the different strands of research together to generate cells that can be implanted into mice is “an amazing idea.”

Dr. Hardikar, who was not involved in the study, said, however, the publication of the study as a correspondence “does not allow for a lot of the detail that I would have expected as an academic,” and consequently some questions remain.

The most important is whether the music itself is required to trigger the insulin release, as opposed simply to sounds in general.

Is Music or Sound the “Trigger?”

Music is “frequency, it’s the amplitude of the waveform, and it’s the duration for which those waveforms are present,” he noted, but the same profile can be achieved by cutting up and editing the melody so it becomes a jumble of sounds.

For Dr. Hardikar, the “best control” for the study would be to have no music as well as the edited song, with “bits of pieces” played randomly so “it sounds like it’s the same frequency and amplitude.”

Then it would be clear whether the effect is owing to the “noise, or we have to appreciate the melody.”

The other outstanding question is whether the results “can directly translate to larger animals,” such as humans, Dr. Hardikar said.

The authors point out that when translated into mechanical vibrations in the middle ear, the acoustic waves of music activate mechanosensitive ion channels, a form of trigger that is seen across the animal kingdom.

They go on to highlight that while gene switches have been developed for use in next-generation cell-based therapies for a range of conditions, small-molecular trigger compounds face a number of challenges and may cause adverse effects.

With “traceless triggers” such as light, ultrasound, magnetic fields, radio waves, electricity, and heat also facing issues, there is a “need for new switching modalities.”

The researchers therefore developed a music-inducible cellular control (MUSIC) system, which leverages the known intracellular calcium surge in response to music, via calcium-permeable mechanosensitive channels, to drive the release of biopharmaceuticals from vesicles.

They then generated MUSIC-controlled insulin-releasing cell lines, finding that, using a customized box containing off-the-shelf loudspeakers, they could induce channel activation and insulin release with 60 dB at 50 Hz, which is “within the safe range for the human ear.”

Further experiments revealed that insulin release was greatest at 50-100 Hz, and higher than that seen with potassium chloride, the “gold-standard” depolarization control for calcium channels.

The researchers then showed that with optimal stimulation at 50 Hz and 60 dB, channel activation and subsequent insulin release required at least 3 seconds of continuous music, “which might protect the cellular device from inadvertent activation during everyday activities.”

Next, they examined the impact of different musical genres on insulin release, finding that low-bass heavy popular music and movie soundtracks induced maximum release, while the responses were more diverse to classical and guitar-based music.

Specifically, “We Will Rock You,” by the British rock band Queen, induced the release of 70% of available insulin within 5 minutes and 100% within 15 minutes. This, the team notes, is “similar to the dynamics of glucose-triggered insulin release by human pancreatic islets.”

Exposing the cells to a second music session at different intervals revealed that full insulin refill was achieved within 4 hours, which “would be appropriate to attenuate glycemic excursions associated with typical dietary habits.”

Finally, the researchers tested the system in vivo, constructing a box with two off-the-shelf loudspeakers that focuses acoustic waves, via deflectors, onto the abdomens of mice with type 1 diabetes.

Exposing the mice, which had been implanted with microencapsulated MUSIC cells in the peritoneum, to low-bass acoustic waves at 60 dB (50 m/s2) for 15 minutes allowed them to achieve near wild-type levels of insulin in the blood and restored normoglycemia.

Moreover, “Queen’s song ‘We Will Rock You’ generated sufficient insulin to rapidly attenuate postprandial glycemic excursions during glucose tolerance tests,” the team says.

In contrast, animals without implants, or those that had implants but did not have music immersion, remained severely hyperglycemic, they add.

They also note that the effect was seen only when the sound waves “directly impinge on the skin just above the implantation site” for at least 15 minutes, with no increase in insulin release observed with commercially available headphones or ear plugs, such as Apple AirPods, or with loud environmental noises.

Consequently, “therapeutic MUSIC sessions would still be compatible with listening to other types of music or listening to all types of music via headphones,” the researchers write, and are “compatible with standard drug administration schemes.”

The study was supported by a European Research Council advanced grant and in part by the Swiss National Science Foundation NCCR Molecular Systems Engineering. One author acknowledges the support of the Chinese Scholarship Council.

For much of his life, 32-year-old Michael Smith had a war going on in his head.

After a big meal, he knew he should be full. But an inexplicable hunger would drive him to pick up the fork again. 

Cravings for fried chicken or gummy bears overwhelmed him, fueling late-night DoorDash orders that — despite their bounty of fat and sugar — never satisfied him.

He recalls waking up on the couch, half-eaten takeout in his lap, feeling sluggish and out of control. 

“It was like I was food drunk,” recalls Smith, who lives in Boston. “I had a moment I looked at myself in the mirror. I was around 380 pounds, and I said, ‘OK, something has got to give.’ “ 

Smith is among the 42% of U.S. adults living with obesity, a misunderstood and stubbornly hard-to-manage condition that doctors have only recently begun to call a disease. Its root causes have been debated for decades, with studies suggesting everything from genes to lifestyle to a shifting food supply loaded with carbohydrates and ultra-processed foods. Solutions have long targeted self-discipline and a simple “eat less, move more” strategy with remarkably grim results. 

Those who successfully slim down tend to gain back 50% of that weight within 2 years, and 80% within 5 years. Meanwhile, the obesity epidemic marches on.

But a new frontier of brain-based therapies — from GLP-1 agonist drugs thought to act on reward and appetite centers to deep brain stimulation aimed at resetting neural circuits — has kindled hope among patients like Smith and the doctors who treat them. The treatments, and theories behind them, are not without controversy. They’re expensive, have side effects, and, critics contend, pull focus from diet and exercise. 

But most agree that in the battle against obesity, one crucial organ has been overlooked.

“Obesity, in almost all circumstances, is most likely a disorder of the brain,” said Casey Halpern, MD, associate professor of neurosurgery at the University of Pennsylvania. “What these individuals need is not simply more willpower, but the therapeutic equivalent of an electrician that can make right these connections inside their brain.”

A Break in the Machine

Throughout the day, the machine that is our brain is constantly humming in the background, taking in subtle signals from our gut, hormones, and environment to determine when we’re hungry, how food makes us feel, and whether we are taking in enough energy, or expending too much, to survive.

“We like to think that we have control over what we eat, but the brain is also integrating all of these factors that we don’t fully understand in ways that shape our decisions,” said Kevin Hall, PhD, an obesity researcher with the National Institute of Diabetes and Digestive and Kidney Diseases. “I liken it to holding your breath. I can do that for a period of time, and I have some conscious control. But eventually, physiology wins out.”

Mounting evidence suggests that in people with obesity, something in the machine is broken.

One seminal 2001 study in The Lancet suggested that, like people addicted to cocaine or alcohol, they lack receptors to the feel-good brain chemical dopamine and overeat in pursuit of the pleasure they lack. 

A recent study, not yet published, from Dr. Hall’s lab drew a slightly different conclusion, suggesting that people with obesity actually have too much dopamine, filling up those receptors so the pleasure spike from eating doesn’t feel like much.

“It’s kind of like trying to shout in a noisy room. You’re going to have to shout louder to have the same effect,” said Dr. Hall.

Gut-brain pathways that tell us we’re full may also be impaired.

In another study, Yale researchers tube-fed 500 calories of sugar or fat directly into the stomachs of 28 lean people and 30 people with obesity. Then they observed brain activity using functional magnetic resonance imaging (fMRI).

In lean people, about 30 regions of the brain quieted after the meal, including parts of the striatum (associated with cravings).

In those with obesity, the brain barely responded at all. 

“In my clinic, patients will often say ‘I just finished my dinner, but it doesn’t feel like it,’” said senior author Mireille Serlie, MD, PhD, an obesity researcher at the Yale School of Medicine. “It may be that this nutrient-sensing interaction between the gut and the brain is less pronounced or comes too late for them after the meal.”

Dr. Halpern recently identified a brain circuit linking a memory center (hippocampus) to an appetite control region (hypothalamus). In people with obesity and binge eating disorder, the circuit appears jammed. This may cause them to, in a sense, forget they just ate.

“Some of their eating episodes are almost dissociative — they’re not realizing how much they are eating and can’t keep track of it,” he said.

Another brain system works to maintain longer-term homeostasis — or weight stability. Like a set thermostat, it kicks on to trigger hunger and fatigue when it senses we’re low on fat.

The hormone leptin, found in fat cells, sends signals to the hypothalamus to let it know how much energy we have on board.

“If leptin levels go up, it signals the brain that you have too much fat and you should eat less to return to the starting point,” said Rockefeller University geneticist Jeffrey Friedman, MD, PhD, who discovered the hormone in 1994. “If you have too little fat and leptin is low, that will stimulate appetite to return you to the starting point.”

In people with obesity, he said, the thermostat — or set point the body seeks to maintain — is too high.

All this raises a crucial question: How do these circuits and pathways malfunction in the first place?

What Breaks the Brain?

Genes, scientists agree, play a role. 

Studies show that genetics underlie as much as 75% of people’s differences in body mass index (BMI), with certain gene combinations raising obesity risk in particular environments. 

While hundreds of genes are believed to have a small effect, about a dozen single genes are thought to have a large effect. (Notably, most influence brain function.) For instance, about 6% of people with severe obesity since childhood have mutations in a gene called MC4R (melanocortin 4 receptor), which influences leptin signaling.

Still, genetics alone cannot account for the explosion in obesity in the U.S. over the last 50 years, says epidemiologist Deirdre Tobias, ScD, assistant professor of medicine at Harvard Medical School.

At the population level, “our genes don’t change that much in less than a generation,” she said.

But our food supply has.

Ultra-processed foods — those containing hydrogenated oils, high-fructose corn syrup, flavoring agents, emulsifiers, and other manufactured ingredients — now make up about 60% of the food supply.

“The evidence is fairly consistent indicating that there’s something about these foods that is possibly causing obesity,” said Tobias. 

In one telling 2019 study, Dr. Hall and his colleagues brought 20 men and women into a study center to live for a month and tightly controlled their food intake and activity. One group was provided with meals with 80% of calories from ultra-processed food. The other was given meals with no processed food. 

The three daily meals provided had the same calories, sugars, fats, fiber, and carbohydrates, and people were told to eat as much as they wanted.

Those on the ultra-processed diet ate about 500 calories more per day, ate faster, and gained weight. Those on the unprocessed diet lost weight.

“This is a stark example of how, when you can change the food environment, you cause really remarkable changes in food intake without people even being aware that they are overeating,” said Dr. Hall. 

Just what it is about these relatively novel foods that may trigger overeating is unclear. It could be the crunch, the lack of water content, the engineered balance of sugar/salt/fat, their easy-to-devour texture, or something else. 

Some research suggests that the foods may interfere with gut-brain signaling that tells the brain you’re full. 

“Evidence is amassing that the nutritional content of processed foods is not accurately conveyed to the brain,” Dana M. Small, PhD, a neuroscientist at Yale, wrote in a recent perspective paper in Science. 

Even more concerning: Some animal studies suggest processed foods reprogram the brain to dislike healthy foods.

And once these brain changes are made, they are hard to reverse.

“The problem is, our brain is not wired for this,” said Dr. Halpern. “We are not evolved to eat the food we are eating, so our brain adapts, but it adapts in a negative way that puts us at risk.”

That’s why changing the food environment via public policy must be part of the solution in combating obesity, Dr. Tobias said.

A New Era of Brain-Based Solutions

In the spring of 2021, after years of trying and failing to lose weight via the “move more, eat less” model, Michael Smith began to take a medication called Vyvanse. The drug was approved in 2008 for attention deficit hyperactivity disorder, but since it also influences levels of the hormones dopamine and norepinephrine to reduce cravings, it is now frequently prescribed for binge eating disorder.

“That was pretty much how I got rid of my first 60 to 70 pounds,” Smith said.

A few months later, after he hit a plateau, he had surgery to shrink the size of his stomach — a decision he now second-guesses. 

While it kept him from overeating for a time, the fried chicken and gummy bear cravings returned a few months later.

His doctor, Fatima Cody Stanford, MD, put him on a second medication: semaglutide, or Wegovy, the weekly shot approved for weight loss in 2021. It works, in part, by mimicking glucagon-like peptide-1 (GLP-1), a key gut hormone that lets your brain know you are full. 

The weight began to fall off again.

Smith’s success story is just one of many that Dr. Stanford, an obesity medicine doctor-scientist at Harvard, has heard in her office in recent years.

“I do not believe these drugs are a panacea,” she said. “There are nonresponders, and those are the patients I take off the medication. But for the high-responders, and there are many of them, they are telling me, ‘Oh my gosh. For the first time in my life, I am not constantly thinking about eating. My life has changed.’” 

A Multi-Pronged Approach

Dr. Halpern, at Penn, has also been hearing success stories.

In recent years, he has placed permanent electrodes in the brains of three people with grade III, or severe, obesity and binge eating disorder. 

All had tried exercise, dieting, support groups, medication, and weight loss surgery to no avail.

The electrodes modulate an area in the center of the brain called the nucleus accumbens, which in mice studies has been shown to reduce cravings when stimulated.

Thus far, all three are seeing promising results.

“It’s not like I don’t think about food at all,” one of them, Robyn Baldwin, told The New York Times. “But I’m no longer a craving person.”

Dr. Halpern is now extending the trial to more patients and hopes to ultimately include other areas of the brain, including those that involve memory.

He imagines a day when people with severe obesity, who have failed conventional treatments, can walk into a clinic and have their brain circuits assessed to see which ones may be misfiring.

Many might find relief with noninvasive brain stimulation, like transcranial magnetic stimulation (already in use for depression). Others might need a more extreme approach, like the deep brain stimulation, or DBS, therapy Dr. Halpern used.

“Obviously, DBS is hard to scale, so it would have to be reserved for the most severe patients,” he said.

Still, not everyone believes brain-based drugs and surgeries are the answer. 

David Ludwig, MD, PhD, a professor of nutrition at the Harvard School of Public Health, played a key role in the discovery of GLP-1 and acknowledges that “of course” the brain influences body composition. But to him, explaining obesity as a disease of the brain oversimplifies it, discounting metabolic factors such as a tendency to store too much fat.

He noted that it’s hard to get drug companies, or any agencies, to fund large clinical trials on simple things like low-carbohydrate diets or exercise programs.

“We need all the tools we can get in the battle against the obesity epidemic, and new technologies are worth exploring,” he said. “However, the success of these drugs should not lead us to deprioritize diet and lifestyle interventions.” 

Dr. Stanford, who has received consulting fees from Wegovy, believes the future of treatment lies in a multi-pronged approach, with surgery, medication, and lifestyle changes coalescing in a lasting, but fragile, remission.

“Unfortunately, there is no cure for obesity,” said Dr. Stanford, whose patients often have setbacks and must try new strategies. “There are treatments that work for a while, but they are constantly pushing up against this origin in the brain.”

Smith says understanding this has been a big part of his success.

He is now a leaner and healthier 5-foot-6 and 204 pounds. In addition to taking his medication, he walks to work, goes to the gym twice a week, limits his portions, and tries to reframe the way he thinks about food, viewing it as fuel rather than an indulgence.

Sometimes, when he looks in the mirror, he is reminded of his 380-pound self, and it scares him. He doesn’t want to go back there. He’s confident now that he won’t have to.

“There is this misconception out there that you just need to put the fork down, but I’m learning it’s more complicated than that,” he said. “I intend to treat this as the illness that it is and do what I need to combat it so I’m able to keep this new reality I have built for myself.”

For much of his life, 32-year-old Michael Smith had a war going on in his head.

After a big meal, he knew he should be full. But an inexplicable hunger would drive him to pick up the fork again. 

Cravings for fried chicken or gummy bears overwhelmed him, fueling late-night DoorDash orders that — despite their bounty of fat and sugar — never satisfied him.

He recalls waking up on the couch, half-eaten takeout in his lap, feeling sluggish and out of control. 

“It was like I was food drunk,” recalls Smith, who lives in Boston. “I had a moment I looked at myself in the mirror. I was around 380 pounds, and I said, ‘OK, something has got to give.’ “ 

Smith is among the 42% of U.S. adults living with obesity, a misunderstood and stubbornly hard-to-manage condition that doctors have only recently begun to call a disease. Its root causes have been debated for decades, with studies suggesting everything from genes to lifestyle to a shifting food supply loaded with carbohydrates and ultra-processed foods. Solutions have long targeted self-discipline and a simple “eat less, move more” strategy with remarkably grim results. 

Those who successfully slim down tend to gain back 50% of that weight within 2 years, and 80% within 5 years. Meanwhile, the obesity epidemic marches on.

But a new frontier of brain-based therapies — from GLP-1 agonist drugs thought to act on reward and appetite centers to deep brain stimulation aimed at resetting neural circuits — has kindled hope among patients like Smith and the doctors who treat them. The treatments, and theories behind them, are not without controversy. They’re expensive, have side effects, and, critics contend, pull focus from diet and exercise. 

But most agree that in the battle against obesity, one crucial organ has been overlooked.

“Obesity, in almost all circumstances, is most likely a disorder of the brain,” said Casey Halpern, MD, associate professor of neurosurgery at the University of Pennsylvania. “What these individuals need is not simply more willpower, but the therapeutic equivalent of an electrician that can make right these connections inside their brain.”

A Break in the Machine

Throughout the day, the machine that is our brain is constantly humming in the background, taking in subtle signals from our gut, hormones, and environment to determine when we’re hungry, how food makes us feel, and whether we are taking in enough energy, or expending too much, to survive.

“We like to think that we have control over what we eat, but the brain is also integrating all of these factors that we don’t fully understand in ways that shape our decisions,” said Kevin Hall, PhD, an obesity researcher with the National Institute of Diabetes and Digestive and Kidney Diseases. “I liken it to holding your breath. I can do that for a period of time, and I have some conscious control. But eventually, physiology wins out.”

Mounting evidence suggests that in people with obesity, something in the machine is broken.

One seminal 2001 study in The Lancet suggested that, like people addicted to cocaine or alcohol, they lack receptors to the feel-good brain chemical dopamine and overeat in pursuit of the pleasure they lack. 

A recent study, not yet published, from Dr. Hall’s lab drew a slightly different conclusion, suggesting that people with obesity actually have too much dopamine, filling up those receptors so the pleasure spike from eating doesn’t feel like much.

“It’s kind of like trying to shout in a noisy room. You’re going to have to shout louder to have the same effect,” said Dr. Hall.

Gut-brain pathways that tell us we’re full may also be impaired.

In another study, Yale researchers tube-fed 500 calories of sugar or fat directly into the stomachs of 28 lean people and 30 people with obesity. Then they observed brain activity using functional magnetic resonance imaging (fMRI).

In lean people, about 30 regions of the brain quieted after the meal, including parts of the striatum (associated with cravings).

In those with obesity, the brain barely responded at all. 

“In my clinic, patients will often say ‘I just finished my dinner, but it doesn’t feel like it,’” said senior author Mireille Serlie, MD, PhD, an obesity researcher at the Yale School of Medicine. “It may be that this nutrient-sensing interaction between the gut and the brain is less pronounced or comes too late for them after the meal.”

Dr. Halpern recently identified a brain circuit linking a memory center (hippocampus) to an appetite control region (hypothalamus). In people with obesity and binge eating disorder, the circuit appears jammed. This may cause them to, in a sense, forget they just ate.

“Some of their eating episodes are almost dissociative — they’re not realizing how much they are eating and can’t keep track of it,” he said.

Another brain system works to maintain longer-term homeostasis — or weight stability. Like a set thermostat, it kicks on to trigger hunger and fatigue when it senses we’re low on fat.

The hormone leptin, found in fat cells, sends signals to the hypothalamus to let it know how much energy we have on board.

“If leptin levels go up, it signals the brain that you have too much fat and you should eat less to return to the starting point,” said Rockefeller University geneticist Jeffrey Friedman, MD, PhD, who discovered the hormone in 1994. “If you have too little fat and leptin is low, that will stimulate appetite to return you to the starting point.”

In people with obesity, he said, the thermostat — or set point the body seeks to maintain — is too high.

All this raises a crucial question: How do these circuits and pathways malfunction in the first place?

What Breaks the Brain?

Genes, scientists agree, play a role. 

Studies show that genetics underlie as much as 75% of people’s differences in body mass index (BMI), with certain gene combinations raising obesity risk in particular environments. 

While hundreds of genes are believed to have a small effect, about a dozen single genes are thought to have a large effect. (Notably, most influence brain function.) For instance, about 6% of people with severe obesity since childhood have mutations in a gene called MC4R (melanocortin 4 receptor), which influences leptin signaling.

Still, genetics alone cannot account for the explosion in obesity in the U.S. over the last 50 years, says epidemiologist Deirdre Tobias, ScD, assistant professor of medicine at Harvard Medical School.

At the population level, “our genes don’t change that much in less than a generation,” she said.

But our food supply has.

Ultra-processed foods — those containing hydrogenated oils, high-fructose corn syrup, flavoring agents, emulsifiers, and other manufactured ingredients — now make up about 60% of the food supply.

“The evidence is fairly consistent indicating that there’s something about these foods that is possibly causing obesity,” said Tobias. 

In one telling 2019 study, Dr. Hall and his colleagues brought 20 men and women into a study center to live for a month and tightly controlled their food intake and activity. One group was provided with meals with 80% of calories from ultra-processed food. The other was given meals with no processed food. 

The three daily meals provided had the same calories, sugars, fats, fiber, and carbohydrates, and people were told to eat as much as they wanted.

Those on the ultra-processed diet ate about 500 calories more per day, ate faster, and gained weight. Those on the unprocessed diet lost weight.

“This is a stark example of how, when you can change the food environment, you cause really remarkable changes in food intake without people even being aware that they are overeating,” said Dr. Hall. 

Just what it is about these relatively novel foods that may trigger overeating is unclear. It could be the crunch, the lack of water content, the engineered balance of sugar/salt/fat, their easy-to-devour texture, or something else. 

Some research suggests that the foods may interfere with gut-brain signaling that tells the brain you’re full. 

“Evidence is amassing that the nutritional content of processed foods is not accurately conveyed to the brain,” Dana M. Small, PhD, a neuroscientist at Yale, wrote in a recent perspective paper in Science. 

Even more concerning: Some animal studies suggest processed foods reprogram the brain to dislike healthy foods.

And once these brain changes are made, they are hard to reverse.

“The problem is, our brain is not wired for this,” said Dr. Halpern. “We are not evolved to eat the food we are eating, so our brain adapts, but it adapts in a negative way that puts us at risk.”

That’s why changing the food environment via public policy must be part of the solution in combating obesity, Dr. Tobias said.

A New Era of Brain-Based Solutions

In the spring of 2021, after years of trying and failing to lose weight via the “move more, eat less” model, Michael Smith began to take a medication called Vyvanse. The drug was approved in 2008 for attention deficit hyperactivity disorder, but since it also influences levels of the hormones dopamine and norepinephrine to reduce cravings, it is now frequently prescribed for binge eating disorder.

“That was pretty much how I got rid of my first 60 to 70 pounds,” Smith said.

A few months later, after he hit a plateau, he had surgery to shrink the size of his stomach — a decision he now second-guesses. 

While it kept him from overeating for a time, the fried chicken and gummy bear cravings returned a few months later.

His doctor, Fatima Cody Stanford, MD, put him on a second medication: semaglutide, or Wegovy, the weekly shot approved for weight loss in 2021. It works, in part, by mimicking glucagon-like peptide-1 (GLP-1), a key gut hormone that lets your brain know you are full. 

The weight began to fall off again.

Smith’s success story is just one of many that Dr. Stanford, an obesity medicine doctor-scientist at Harvard, has heard in her office in recent years.

“I do not believe these drugs are a panacea,” she said. “There are nonresponders, and those are the patients I take off the medication. But for the high-responders, and there are many of them, they are telling me, ‘Oh my gosh. For the first time in my life, I am not constantly thinking about eating. My life has changed.’” 

A Multi-Pronged Approach

Dr. Halpern, at Penn, has also been hearing success stories.

In recent years, he has placed permanent electrodes in the brains of three people with grade III, or severe, obesity and binge eating disorder. 

All had tried exercise, dieting, support groups, medication, and weight loss surgery to no avail.

The electrodes modulate an area in the center of the brain called the nucleus accumbens, which in mice studies has been shown to reduce cravings when stimulated.

Thus far, all three are seeing promising results.

“It’s not like I don’t think about food at all,” one of them, Robyn Baldwin, told The New York Times. “But I’m no longer a craving person.”

Dr. Halpern is now extending the trial to more patients and hopes to ultimately include other areas of the brain, including those that involve memory.

He imagines a day when people with severe obesity, who have failed conventional treatments, can walk into a clinic and have their brain circuits assessed to see which ones may be misfiring.

Many might find relief with noninvasive brain stimulation, like transcranial magnetic stimulation (already in use for depression). Others might need a more extreme approach, like the deep brain stimulation, or DBS, therapy Dr. Halpern used.

“Obviously, DBS is hard to scale, so it would have to be reserved for the most severe patients,” he said.

Still, not everyone believes brain-based drugs and surgeries are the answer. 

David Ludwig, MD, PhD, a professor of nutrition at the Harvard School of Public Health, played a key role in the discovery of GLP-1 and acknowledges that “of course” the brain influences body composition. But to him, explaining obesity as a disease of the brain oversimplifies it, discounting metabolic factors such as a tendency to store too much fat.

He noted that it’s hard to get drug companies, or any agencies, to fund large clinical trials on simple things like low-carbohydrate diets or exercise programs.

“We need all the tools we can get in the battle against the obesity epidemic, and new technologies are worth exploring,” he said. “However, the success of these drugs should not lead us to deprioritize diet and lifestyle interventions.” 

Dr. Stanford, who has received consulting fees from Wegovy, believes the future of treatment lies in a multi-pronged approach, with surgery, medication, and lifestyle changes coalescing in a lasting, but fragile, remission.

“Unfortunately, there is no cure for obesity,” said Dr. Stanford, whose patients often have setbacks and must try new strategies. “There are treatments that work for a while, but they are constantly pushing up against this origin in the brain.”

Smith says understanding this has been a big part of his success.

He is now a leaner and healthier 5-foot-6 and 204 pounds. In addition to taking his medication, he walks to work, goes to the gym twice a week, limits his portions, and tries to reframe the way he thinks about food, viewing it as fuel rather than an indulgence.

Use of pharmacomechanical catheter-directory thrombolysis significantly reduced the number of pulmonary artery branches with total or subtotal occlusions in patients with acute pulmonary embolism, based on data from more than 100 individuals.

Reduced distal vascular volume is a significant predictor of 30-day and 90-day mortality in acute pulmonary embolism (PE) patients, and pulmonary obstruction is often the cause, wrote Riyaz Bashir, MD, of Temple University, Philadelphia, Pennsylvania, and colleagues.

Some studies of catheter-based treatments have shown a reduction in pulmonary artery (PA) obstruction in PE patients, but the impact has been modest, the researchers said.

“The recently published RESCUE (Recombinant tPA by Endovascular Administration for the Treatment of Submassive PE Using CDT for the Reduction of Thrombus Burden) trial showed a 35.9% reduction in PA obstruction using the Refined Modified Miller Index (RMMI), the largest reduction of all published catheter studies with core lab measurement, with similar doses of tissue plasminogen activator (tPA),” the researchers wrote.

The Bashir endovascular catheter was designed to maximize thrombus reduction via a pharmacomechanical infusion. The catheter features an expandable basket of 6 nitinol-reinforced infusion limbs.

“There are three crucial goals that we want to accomplish in patients who have a severe pulmonary embolism,” Dr. Bashir said in an interview. “Those include, in the order of importance, survival, recovery of right ventricular function, and resolution of blocked pulmonary arteries; both segmental and proximal pulmonary arteries,” he said.

Most previous studies have focused on the first two goals, but they still need to evaluate the resolution of PA blockages carefully, said Dr. Bashir. “In our clinical practice, we have seen a large number of patients who develop debilitating shortness of breath from these blockages. We decided to carefully evaluate these blockages before and after pharmacomechanical catheter-directed thrombolysis with the Bashir endovascular catheter using the core lab data from the RESCUE study,” he said.

In the current study published in JACC: Advances), the researchers used baseline and 48-hour posttreatment contrast-enhanced chest computed tomography angiography of adult PE patients with right ventricular dilatation.

The study population included 107 adults with acute intermediate-risk PE who were treated with pharmacomechanical catheter-directory thrombolysis (PM-CDT) at 18 sites in the United States. Of these, 98 had intermediate high-risk PE with elevated troponin and/or brain-type natriuretic peptide (BNP) levels and 102 had bilateral PE.

The primary endpoint was the change in the number of segmental and proximal PA branches with total or subtotal occlusions (defined as > 65%) after 48 hours compared to baseline. Occlusions were assessed using McNemar’s test.

Patients with bilateral PE received two Bashir catheters; those with unilateral PE received one catheter each.

Each patient received a pulse spray of 2 mg of recombinant tPA (r-tPA) into each lung, followed by 5 mg of r-tPA over 5 hours; the total dose was 7 mg of r-tPA for patients with unilateral PEs and 14 mg for those with bilateral PEs, the researchers said. The median times for catheter placement and total procedure were 15 minutes and 54 minutes, respectively.

The number of segmental PA branches with total or subtotal occlusions decreased significantly, from 40.5% at baseline to 11.7% at 48 hours, and proximal PA branch total or subtotal occlusions decreased significantly, from 28.7% at baseline to 11.0% at 48 hours (P < 0.0001 for both).

The magnitude of the reductions in both total and subtotal occlusions of segmental arteries was significantly correlated with the extent of right ventricle recovery (measured by the reduction in right ventricular/left ventricular ratio) with a correlation coefficient of 0.287 (P = .0026); however, this correlation was not observed in the proximal PA arteries (correlation coefficient 0.132, P = .173).

One major bleeding event occurred within 72 hours in a patient who also experienced a device-related left common iliac vein thrombosis while not taking anticoagulation medication, and one death unrelated to PE occurred within 30 days.

“The two findings that surprised me include, first, a more than 70% reduction in total and subtotal occlusions in the segmental arteries with such a low dose of r-tPA and, second, the resolution of the blockages was seen not only in the arteries where the device was placed but also at remote sites away from the location of the catheter,” Dr. Bashir told this news organization.

The findings were limited by several factors including the lack of long-term clinical follow-up outcomes data and lack of comparison groups who underwent other treatments.

However, “This study implies that we now have a safe therapy for these patients that improves survival and right ventricular recovery in addition to dramatically improving blocked pulmonary arteries,” Dr. Bashir said.

As for additional research, “we need all the current and future prospective pulmonary embolism studies to include an assessment of pulmonary artery blockage resolution as an essential endpoint,” he said.
 

Catheter Expands Treatment Options

The current study, a subgroup analysis of the RESCUE trial, was one of the first to examine the impact of catheter-directed lysis on distal occlusions, study coauthor Parth M. Rali, MD, said in an interview.

To this point, literature has been limited to evaluation for proximal disease, said Dr. Rali, director of thoracic surgery and medicine and part of the Pulmonary Embolism Response Team at Temple University Hospital, Philadelphia.

Dr. Rali said he was encouraged to see confirmation that the BEC catheter, because of its design, works in patients with proximal or distal occlusive disease.

In clinical practice, “the catheter provides an additional option for care in patients with multiple distal occlusive disease when a systemic tissue plasminogen activator (tPA), may put patient at high bleeding risk,” Dr. Rali said.

Looking ahead, a prospective, observational multicenter study would be useful to validate the findings from the post hoc analysis of the current study, he noted.

The study was sponsored by the National Heart, Lung, and Blood Institute, Commonwealth of Pennsylvania, and Thrombolex Inc., a medical device company developing interventional catheter-based therapies for the rapid and effective treatment of acute venous thromboembolic disorders. Dr. Bashir is a cofounder and has an equity interest in Thrombolex Inc. Dr. Rali disclosed serving as a consultant for Thrombolex, Inari Medical, Viz AI, and ThinkSono.

Use of pharmacomechanical catheter-directory thrombolysis significantly reduced the number of pulmonary artery branches with total or subtotal occlusions in patients with acute pulmonary embolism, based on data from more than 100 individuals.

Reduced distal vascular volume is a significant predictor of 30-day and 90-day mortality in acute pulmonary embolism (PE) patients, and pulmonary obstruction is often the cause, wrote Riyaz Bashir, MD, of Temple University, Philadelphia, Pennsylvania, and colleagues.

Some studies of catheter-based treatments have shown a reduction in pulmonary artery (PA) obstruction in PE patients, but the impact has been modest, the researchers said.

“The recently published RESCUE (Recombinant tPA by Endovascular Administration for the Treatment of Submassive PE Using CDT for the Reduction of Thrombus Burden) trial showed a 35.9% reduction in PA obstruction using the Refined Modified Miller Index (RMMI), the largest reduction of all published catheter studies with core lab measurement, with similar doses of tissue plasminogen activator (tPA),” the researchers wrote.

The Bashir endovascular catheter was designed to maximize thrombus reduction via a pharmacomechanical infusion. The catheter features an expandable basket of 6 nitinol-reinforced infusion limbs.

“There are three crucial goals that we want to accomplish in patients who have a severe pulmonary embolism,” Dr. Bashir said in an interview. “Those include, in the order of importance, survival, recovery of right ventricular function, and resolution of blocked pulmonary arteries; both segmental and proximal pulmonary arteries,” he said.

Most previous studies have focused on the first two goals, but they still need to evaluate the resolution of PA blockages carefully, said Dr. Bashir. “In our clinical practice, we have seen a large number of patients who develop debilitating shortness of breath from these blockages. We decided to carefully evaluate these blockages before and after pharmacomechanical catheter-directed thrombolysis with the Bashir endovascular catheter using the core lab data from the RESCUE study,” he said.

In the current study published in JACC: Advances), the researchers used baseline and 48-hour posttreatment contrast-enhanced chest computed tomography angiography of adult PE patients with right ventricular dilatation.

The study population included 107 adults with acute intermediate-risk PE who were treated with pharmacomechanical catheter-directory thrombolysis (PM-CDT) at 18 sites in the United States. Of these, 98 had intermediate high-risk PE with elevated troponin and/or brain-type natriuretic peptide (BNP) levels and 102 had bilateral PE.

The primary endpoint was the change in the number of segmental and proximal PA branches with total or subtotal occlusions (defined as > 65%) after 48 hours compared to baseline. Occlusions were assessed using McNemar’s test.

Patients with bilateral PE received two Bashir catheters; those with unilateral PE received one catheter each.

Each patient received a pulse spray of 2 mg of recombinant tPA (r-tPA) into each lung, followed by 5 mg of r-tPA over 5 hours; the total dose was 7 mg of r-tPA for patients with unilateral PEs and 14 mg for those with bilateral PEs, the researchers said. The median times for catheter placement and total procedure were 15 minutes and 54 minutes, respectively.

The number of segmental PA branches with total or subtotal occlusions decreased significantly, from 40.5% at baseline to 11.7% at 48 hours, and proximal PA branch total or subtotal occlusions decreased significantly, from 28.7% at baseline to 11.0% at 48 hours (P < 0.0001 for both).

The magnitude of the reductions in both total and subtotal occlusions of segmental arteries was significantly correlated with the extent of right ventricle recovery (measured by the reduction in right ventricular/left ventricular ratio) with a correlation coefficient of 0.287 (P = .0026); however, this correlation was not observed in the proximal PA arteries (correlation coefficient 0.132, P = .173).

One major bleeding event occurred within 72 hours in a patient who also experienced a device-related left common iliac vein thrombosis while not taking anticoagulation medication, and one death unrelated to PE occurred within 30 days.

“The two findings that surprised me include, first, a more than 70% reduction in total and subtotal occlusions in the segmental arteries with such a low dose of r-tPA and, second, the resolution of the blockages was seen not only in the arteries where the device was placed but also at remote sites away from the location of the catheter,” Dr. Bashir told this news organization.

I’m Dr Rachel Rubin. I am a urologist with fellowship training in sexual medicine. Today I’m going to explain why I may recommend that your patients put a needle directly into their penises for help with erectile dysfunction (ED).

I know that sounds crazy, but in a recent video when I talked about erection hardness, I acknowledged that it may not be easy to talk with patients about their penises, but it’s important.

ED can be a marker for cardiovascular disease, with 50% of our 50-year-old patients having ED. As physicians, we must do a better job of talking to our patients about ED and letting them know that it’s a marker for overall health.

How do we treat ED? Primary care doctors can do a great deal for patients with ED, and there are other things that urologists can do when you run out of options in your own toolbox.

What’s important for a healthy erection? You need three things: healthy muscle, healthy nerves, and healthy arteries. If anything goes wrong with muscles, nerves, or arteries, this is what leads to ED. Think through the algorithm of your patient’s medical history: Do they have diabetes, which can affect their nerves? Do they have high blood pressure, which can affect their arteries? Do they have problems with testosterone, which can affect the smooth muscles of the penis? Understanding your patient’s history can be really helpful when you figure out what is the best treatment strategy for your patient.

For the penis to work, those smooth muscles have to relax; therefore, your brain has to be relaxed, along with your pelvic floor muscles. The smooth muscle of the penis has to be relaxed so it can fill with blood, increase in girth and size, and hold that erection in place.

To treat ED, we have a biopsychosocial toolbox. Biology refers to the muscles, arteries, and nerves. The psychosocial component is stress: If your brain is stressed, you have a lot of adrenaline around that can tighten those smooth muscles and cause you to lose an erection.

So, what are these treatments? I’ll start with lifestyle. A healthy heart means a healthy penis, so, all of the things you already recommend for lifestyle changes can really help with ED. Sleep is important. Does your patient need a sleep study? Do they have sleep apnea? Are they exercising? Recent data show that exercise may be just as effective, if not more effective, than Viagra. How about a good diet? The Mediterranean diet seems to be the most helpful. So, encourage your patients to make dietary, exercise, sleep, and other lifestyle changes if they want to improve erectile function.

What about sex education? Most physicians didn’t get great education about sex in medical school, but it’s very important to our patients who likewise have had inadequate sex education. Ask questions, talk to them, explain what is normal.

I can’t stress enough how important mental health is to a great sex life. Everyone would benefit from sex therapy and becoming better at sex. We need to get better at communicating and educating patients and their partners to maximize their quality of life. If you need to refer to a specialist, we recommend going to psychologytoday.com or aasect.org to find a local sex therapist. Call them and use them in your referral networks.

In the “bio” component of the biopsychosocial approach, we can do a lot to treat ED with medications and hormones. Testosterone has been shown to help with low libido and erectile function. Checking the patient’s testosterone level can be very helpful. Pills — we are familiar with Viagra, Cialis, Levitra, and Stendra. The oral PDE-5 inhibitors have been around since the late 1990s and they work quite well for many people with ED. Viagra and Cialis are generic now and patients can get them fairly inexpensively with discount coupons from GoodRx or Cost Plus Drugs. They may not even have to worry about insurance coverage.

Pills relax the smooth muscle of the penis so that it fills with blood and becomes erect, but they don’t work for everybody. If pills stop working, we often talk about synergistic treatments — combining pills and devices. Devices for ED should be discussed more often, and clinicians should consider prescribing them. We commonly discuss eyeglasses and wheelchairs, but we don’t talk about the sexual health devices that could help patients have more success and fun in the bedroom.

What are the various types of devices for ED? One common device is a vacuum pump, which can be very effective. This is how they work: The penis is lubricated and placed into the pump. A button on the pump creates suction that brings blood into the penis. The patient then applies a constriction band around the base of the penis to hold that erection in place.

“Sex tech” has really expanded to help patients with ED with devices that vibrate and hold the erection in place. Vibrating devices allow for a better orgasm. We even have devices that monitor erectile fitness (like a Fitbit for the penis), gathering data to help patients understand the firmness of their erections.

Devices are helpful adjuncts, but they don’t always do enough to achieve an erect penis that’s hard enough for penetration. In those cases, we can recommend injections that increase smooth muscle relaxation of the penis. I know it sounds crazy. If the muscles, arteries, and nerves of the penis aren’t functioning well, additional smooth muscle relaxation can be achieved by injecting alprostadil (prostaglandin E1) directly into the penis. It’s a tiny needle. It doesn’t hurt. These injections can be quite helpful for our patients, and we often recommend them.

But what happens when your patient doesn’t even respond to injections or any of the synergistic treatments? They’ve tried everything. Urologists may suggest a surgical option, the penile implant. Penile implants contain a pump inside the scrotum that fills with fluid, allowing a rigid erection. Penile implants are wonderful for patients who can no longer get erections. Talking to a urologist about the pros and the cons and the risks and benefits of surgically placed implants is very important.

Finally, ED is a marker for cardiovascular disease. These patients may need a cardiology workup. They need to improve their general health. We have to ask our patients about their goals and what they care about, and find a toolbox that makes sense for each patient and couple to maximize their sexual health and quality of life. Don’t give up. If you have questions, let us know.

TOPLINE

Babies born to mothers living in disadvantaged neighborhoods have a higher risk of being diagnosed with autism spectrum disorder (ASD), but only if they are White, a population-based prospective cohort study shows. 

METHODOLOGY

• Investigators analyzed data from a large cohort of singleton children with insurance born in Kaiser Permanente Southern California hospitals between 2001 and 2014.
• They ascertained ASD diagnosis, maternal race and ethnicity, and maternal address at time of birth.
• Neighborhood disadvantage was determined by the percentage of families in the mother’s neighborhood considered to be living in poverty, unemployed, have female-headed households with children, using public assistance, less than a high school education, among other variables.

TAKEAWAY

• Among 318,300 mothers who delivered babies during the study period, 6350 children were diagnosed with ASD during follow-up, and median age at diagnosis was 3.5 years.
• Greater neighborhood disadvantage at birth was associated with a higher likelihood of ASD diagnosis (adjusted hazard ratio [aHR], 1.07; 95% CI, 1.02-1.11)
• ASD diagnoses were more likely among children of mothers who were Black (aHR, 1.13; 95% CI, 1.02-1.25), Asian/Pacific Islander (aHR, 1.11; 95% CI, 1.02-1.20), or Hispanic (aHR, 1.07; 95% CI, 1.00-1.15), even after the researchers controlled for neighborhood.
• While odds of an ASD diagnosis were higher among children from minority racial and ethnic groups, neighborhood disadvantage was significantly associated with ASD diagnosis only for children of White mothers (aHR, 1.17; 95% CI, 1.09-1.26).

IN PRACTICE

Investigators noted that they could only speculate about the factors driving the association between neighborhood disadvantage and a stronger risk for ASD diagnosis in children of White mothers. “They may be due to systemic racism, discrimination, and their impact on maternal health during pregnancy,” they wrote.

A study investigating the effectiveness of a pilot program to educate barbers about pseudofolliculitis barbae (PFB) found that the barbers significantly improved their knowledge about the causes, prevention, and treatment of the condition after the educational intervention.

The results were published in a research letter in JAMA Dermatology. “Educating barbers on dermatologic conditions that disproportionately affect Black males and establishing referral services between barbers and dermatologists could serve as plausible interventions,” the authors wrote.

PFB — or “razor bumps” in layman’s terms — is a chronic, inflammatory follicular disorder, which can occur in any racial group, but primarily affects Black men, noted the corresponding author of the study, Xavier Rice, MD, a dermatology resident at Washington University in Saint Louis, Missouri. PFB manifests as bumps and pustules or nodules along the beard line and are painful, he said in an interview. “They tend to leave scars once they resolve,” and impair the ability to shave, he noted.

In some communities, Black men may see their barbers more often than primary care doctors or dermatologists, “so if you equip the barbers with the knowledge to recognize the disease, make recommendations on how to prevent and to treat, and also form some allyship with barbers and dermatologists, then we can get referrals for people, especially the ones with severe disease,” he said. A lot of the barbers in the study said that “they didn’t receive much education on how to properly address it [PFB] and they had a lot of miseducation about what actually caused it,” added Dr. Rice, who was a medical student at the University of Texas Medical Branch, Galveston, when the study was conducted.

Study involved 40 barbers

For the study, Dr. Rice and his coauthors surveyed 40 barbers in the Houston, Texas, area; 39 were Black and one was Hispanic; 75% were men and 25% were women. Most (90%) said that at least 60% of their clients were Black. Between January and April 2022, the barbers received questionnaires before and after participating in a session that involved a review of a comprehensive educational brochure with information on the recognition, cause, prevention, and treatment of PFB, which they then kept for reference and to provide to clients as needed. “Common myths and nuanced home remedies from barber experience were also addressed,” the authors wrote.

No more than 2 weeks after the information session, each barber completed a posttest questionnaire.

Based on their responses to pretest questions, 39 of the 40 barbers understood that Black men were the group most impacted by PFB and that a person with severe PFB should see a physician. In the pretest survey, 12 barbers (30%) correctly recognized a photo of PFB, which increased to 39 (97.5%) in the posttest survey. In the pretest survey, two barbers (5%) identified laser hair removal as the most effective treatment for PFB, compared with 37 (92.5%) in the posttest survey.

Overall, the mean percentage of correct scores out of 20 questions was 54.8% in the pretest survey, increasing to 91% in the posttest survey (P <.001).

Limitations of the studies included heterogeneity in the survey response options that potentially could have introduced bias, the authors wrote. Another was that since there is a lack of evidence for ideal treatment strategies for PFB, there may have been some uncertainty among the correct answers for the survey that might have contributed to variability in responses. “Further research and implementation of these interventions are needed in efforts to improve health outcomes,” they added.

“Barbers can serve as allies in referral services,” Dr. Rice said in the interview. “They can be the first line for a number of diseases that are related to hair.”

Part of his role as a dermatologist, he added, includes going into a community with “boots on the ground” and talking to people who will see these patients “because access to care, presentation to big hospital systems can be challenging.”

Dr. Rice and the other study authors had no not report any financial disclosures.
