According to the CDC, the prevalence of autism spectrum disorders (ASD) has gone from roughly 1 in 68 children in 2010 to 1 in 36 children in 2020.¹ This is nearly a 50% increase over that 10-year period. Over the last several years, there has been evidence suggesting that increasing numbers of young people with ASD or other neurodivergent conditions identify as transgender or gender diverse.² Experts agree more careful attention must be paid to these patients.

Clinical work with neurodivergent youth, especially those with ASD, can be complicated. This includes things such as difficulty with communication, possible concrete thinking, and obsessive interests. While earlier research has shown a higher incidence of ASD in those referred to specialized gender medical clinics, it is important to realize that not all of these youth are seeking medical care. They may be brought to the attention of a primary care pediatrician (PCP) if the child has discussed their gender identity at home. It is important that PCPs approach these young people with an open mind and address any coexisting mental health conditions. PCPs must be careful not to dismiss any gender identity concerns as another of the patient’s “obsessions”; rather, they should ensure the patient receives the appropriate mental health care that they need to explore these concerns. One challenge for PCPs is that there is a dearth of mental health professionals who have experience in working with young people who have both gender dysphoria and a neurodivergent condition.

For those clinicians who provide gender-affirming medical care to these young people, it is imperative that they have a thorough understanding of the patient’s gender identity and medical goals before starting any treatment. This may require extensive collaboration with the patient’s mental health provider. The clinician providing medical care may also choose to proceed slower with the introduction of hormones and their subsequent dosing to allow the young person time to continue discussing their effects with their mental health provider. To help clinicians, Dr. John Strang and a multidisciplinary group of collaborators developed a set of guidelines for co-occurring ASD and gender dysphoria in adolescents.³ More recently, Dr. Strang and other collaborators have also developed a questionnaire that can be used by clinicians in the care of these patients.⁴ The goal of this questionnaire is to allow the young people to “communicate their experiences and needs in a report format attuned to common autistic thinking and communication styles.”

In summary, pediatricians and those who care for children and adolescents need to be aware of the increased association between those with ASD or other neurodivergent conditions and gender dysphoria. To ensure that these young people receive optimal care, it is important to connect them to experts (if possible) in coexisting ASD and gender dysphoria. If such experts are not readily available, the National LGBTQIA+ Health Education Center has developed a resource for providing an affirmative approach to care for these young people.⁵ While more research is needed to better understand young people with coexisting ASD (or other neurodivergent conditions), taking an individualized approach to their care can help ensure optimal outcomes.

TOPLINE:

A topical fixed-dose combination of three approved acne treatments significantly improves moderate to severe acne with a strong safety profile.

METHODOLOGY:

• The two multicenter studies included 363 individuals aged 9 years and older with moderate to severe acne from 30 centers, including 15 in North America.
• Moderate to severe acne was defined as having 30-100 inflammatory lesions (papules, pustules, or nodules), 35-150 noninflammatory lesions (open or closed comedones), and at least two nodules.
• Participants were randomly assigned to receive treatment with a combination gel containing  phosphate 1.2%,  0.15%, and  3.1% (known as IDP-126) or a vehicle gel for once-daily application for 12 weeks.
• Treatment success was defined as a reduction of at least two grades from baseline on the Evaluator’s Global Severity Score (EGSS) and lesion counts of clear (0) or almost clear (1) at weeks 2, 4, 8, and 12.

TAKEAWAY:

• Treatment success occurred in 49.6% of the IDP-126 group, vs 24.9% of the vehicle group in study 1, and in 50.5% of the IDP-126 group, vs 20.5% of the vehicle group in study 2. Overall treatment compliance was 93.7% and 91.3% for studies 1 and 2, respectively (P < .01 for both).
• Patients in the IDP-126 groups for both studies 1 and 2 had significantly greater absolute mean reductions in both inflammatory and noninflammatory lesions from baseline to week 12 compared to the vehicle patients (P ≤ .001 for all).
• Significantly more patients in the IDP-126 group achieved a grade reduction of 2 or more in EGSS compared with those who received the vehicle, with treatment differences of approximately 32% in both studies. Changes in lesion reductions between the treatment and the vehicle groups were significantly greater as early as week 4.
• The most common treatment-related adverse events among patients treated with IDP-126 were erythema, application-site pain, dryness, irritation, and exfoliation. Discontinuation of the study drug as a result of adverse events occurred in 2.5% and 3.3% of these patients in studies 1 and 2, respectively.

IN PRACTICE:

“With its simple treatment regimen containing 3 recommended acne treatments (benzoyl peroxide, a topical retinoid, and a topical antibiotic), IDP-126 is a potential new treatment option for acne,” the researchers concluded.

SOURCE:

The study was led by Linda Stein Gold, MD, of Henry Ford Hospital, Detroit. The study was published online in the Journal of the American Academy of Dermatology.

LIMITATIONS:

In both studies, treatment duration was short, and the studies may not reflect patients’ real-world experiences. The results may be affected by interobserver bias or variation in assessment of acne severity.

DISCLOSURES:

Gold has served as investigator/consultant or speaker for Ortho Dermatologics, LEO Pharma, Dermavant, Incyte, Novartis, AbbVie, Pfizer, Sun Pharma, UCB, Arcutis, and Lilly. Other study coauthors have relationships with multiple companies, including Ortho Dermatologics, which provided medical writing support for the study.

Considerable hair regrowth can be achieved in children with alopecia areata with the use of a novel plant-based drug, according to research presented during the first late-breaking news session at the annual congress of the European Academy of Dermatology and Venereology.

In the RAAINBOW study, a greater mean relative improvement in the Severity of Alopecia Tool (SALT) scores at 24 weeks was recorded in children who had been treated topically with coacillium (22.9%) than in those who had received a topical placebo (–8.0%), with a significant 31% overall difference (P < .0001).

“Coacillium cutaneous solution was used for the first time for treatment of alopecia areata and also for the first time used in a pediatric population,” the presenting investigator Ulrike Blume-Peytavi, MD, said at the meeting.

“It’s well tolerated, and in fact what is interesting is, it has a durable response, even after treatment discontinuation,” added Dr. Blume-Peytavi, who is the deputy head of the department of dermatology, venereology and allergology at Charité-Universitätsmedizin Berlin.
 

Backing the botanical?

Paola Pasquali, MD, a dermatologist at Pius Hospital de Valls in Spain, who cochaired the session where the findings were presented, commented, “Thank you for showing that chocolate is great! I knew it. It is fantastic to see how chocolate is used.”

Dr. Pasquali was referring to the coacillium ingredient Theobroma cacao extract. The seeds of T. cacao, or the cocoa tree, are used to make various types of chocolate products. Theobroma cacao is one of four plant extracts that make up coacillium, the others being Allium cepa (onion), Citrus limon (lemon), and Paullinia cupana (guaraná, a source of caffeine).

The four plant extracts are classified as “generally regarded as safe” (GRAS), Dr. Blume-Peytavi observed, noting that the development of coacillium fell under the category of a prescription botanical drug as set out by the U.S. Food and Drug Administration or a herbal medicinal product as set out by the European Medicines Agency.

But how does it work?

The botanical’s mode of action of acting positively on hair follicle cycling and endothelial cell activation was called into question, however, by Emma Guttman-Yassky, MD, PhD, who was in the audience.

She asked, “So how do you explain that, after three large studies with topical JAK inhibitors that did not work actually in alopecia areata because it’s very hard to penetrate the scalp for a topical [drug], this one works?”

Dr. Guttman-Yassky, professor of dermatology and immunology at the Icahn School of Medicine at Mount Sinai, New York, added: “Looking at the ingredients, to me, it seems that it’s more like a DPCP [diphenylcyclopropenone]-like reaction.”

DPCP, which has been used to treat alopecia, purportedly works by stimulating the immune response to target the skin surface – causing an allergic reaction – rather than the hair follicle.

It’s an interesting question as to how a molecule penetrates the hair follicle, and it depends on the size of the molecule, Dr. Blume-Peytavi responded.

“We have done a lot of studies on follicular penetration, and we are quite aware that you need a certain size of the molecule,” she said. Between 14 and 200 nanometers appears to produce “the best penetrators,” she observed.

Dr. Blume-Peytavi commented that even after topical JAK inhibitors are applied, the molecules that penetrate do not remain in the local area for very long, yet still produce an inhibitory signaling effect.

No scalp irritation was seen in the trial, which suggests that coacillium is not working in the same way as DPCP, Dr. Blume-Peytavi countered.
 

Evaluating efficacy and safety: The RAAINBOW study

Dr. Blume-Peytavi acknowledged that JAK inhibitors were “a tremendous advance in treating severe and very severe alopecia areata,” but because of their benefit-to-risk ratio, there was still an unmet need for new treatments, particularly in children, in whom drug safety is of critical importance.

Having a drug that could be given safely and also have an effect early on in the disease, while it is still at a mild to moderate stage, would be of considerable value, Dr. Blume-Peytavi maintained.

The RAAINBOW study was a randomized, double-blind, phase 2/3 trial conducted at 12 sites in Germany and three other countries between March 2018 and March 2022 to evaluate the efficacy and safety of coacillium in the treatment of children and adolescents with moderate to severe alopecia areata.

In all, 62 children aged 2-18 years (mean age, 11 years) participated; 42 were treated twice daily with coacillium cutaneous solution 22.5% and 20 received placebo for 24 weeks. Treatment was then stopped, and participants followed for another 24 weeks off treatment to check for disease relapse, bringing the total study duration up to 48 weeks.

Baseline characteristics were “relatively comparable for severity,” Dr. Blume-Peytavi said. Most of the children had severe alopecia areata (57% for coacillium and 65% for placebo); the remainder had moderate disease (43% vs. 35%, respectively).

The average SALT scores at the start of treatment were 56 in the coacillium group and 62 in the placebo group, and a respective 44 and 61 at the end of 24 weeks’ treatment.

Perhaps the most important results, Dr. Blume-Peytavi said, was that at 48 weeks of follow-up, which was 24 weeks after treatment had been discontinued, the mean SALT scores were 29 for coacillium and 56 for placebo (P < .0001).

“You can see the improvement in the treated group is continuing even without treatment. However, the placebo group stays relatively about the same range,” she said.

Overall, 82% of patients treated with coacillium and 37% of those who received placebo experienced hair growth after treatment had stopped, and by week 48, a respective 46.7% vs. 9.1% had a SALT score of 20 or less, and 30.0% vs. 0% had a SALT score of 10 or less.

No safety concerns were raised, with no serious treatment-related reactions, no immunosuppressant-like reactions, and no steroidlike side effects.
 

Beyond the RAAINBOW

Larger studies are needed, Dr. Blume-Peytavi said. According to developer Legacy Healthcare’s website, coacillium cutaneous solution is not being developed just for childhood alopecia areata. It is also under investigation as a treatment for persistent chemotherapy-induced alopecia, atopic dermatitis, and psoriasis. In addition, an oral solution is being tested for cancer-related fatigue.

The study was funded by Legacy Healthcare. Dr. Blume-Peytavi has received research funding and acts as an advisor to the company, among others; four of the study’s coauthors are employees of the company. Dr. Pasquali and Dr. Guttman-Yassky were not involved in the study and had no relevant financial ties to disclose.

Dr. Blume-Peytavi acknowledged that JAK inhibitors were “a tremendous advance in treating severe and very severe alopecia areata,” but because of their benefit-to-risk ratio, there was still an unmet need for new treatments, particularly in children, in whom drug safety is of critical importance.

Having a drug that could be given safely and also have an effect early on in the disease, while it is still at a mild to moderate stage, would be of considerable value, Dr. Blume-Peytavi maintained.

The RAAINBOW study was a randomized, double-blind, phase 2/3 trial conducted at 12 sites in Germany and three other countries between March 2018 and March 2022 to evaluate the efficacy and safety of coacillium in the treatment of children and adolescents with moderate to severe alopecia areata.

In all, 62 children aged 2-18 years (mean age, 11 years) participated; 42 were treated twice daily with coacillium cutaneous solution 22.5% and 20 received placebo for 24 weeks. Treatment was then stopped, and participants followed for another 24 weeks off treatment to check for disease relapse, bringing the total study duration up to 48 weeks.

Baseline characteristics were “relatively comparable for severity,” Dr. Blume-Peytavi said. Most of the children had severe alopecia areata (57% for coacillium and 65% for placebo); the remainder had moderate disease (43% vs. 35%, respectively).

The average SALT scores at the start of treatment were 56 in the coacillium group and 62 in the placebo group, and a respective 44 and 61 at the end of 24 weeks’ treatment.

Perhaps the most important results, Dr. Blume-Peytavi said, was that at 48 weeks of follow-up, which was 24 weeks after treatment had been discontinued, the mean SALT scores were 29 for coacillium and 56 for placebo (P < .0001).

“You can see the improvement in the treated group is continuing even without treatment. However, the placebo group stays relatively about the same range,” she said.

Overall, 82% of patients treated with coacillium and 37% of those who received placebo experienced hair growth after treatment had stopped, and by week 48, a respective 46.7% vs. 9.1% had a SALT score of 20 or less, and 30.0% vs. 0% had a SALT score of 10 or less.

No safety concerns were raised, with no serious treatment-related reactions, no immunosuppressant-like reactions, and no steroidlike side effects.
 

Beyond the RAAINBOW

Larger studies are needed, Dr. Blume-Peytavi said. According to developer Legacy Healthcare’s website, coacillium cutaneous solution is not being developed just for childhood alopecia areata. It is also under investigation as a treatment for persistent chemotherapy-induced alopecia, atopic dermatitis, and psoriasis. In addition, an oral solution is being tested for cancer-related fatigue.

The study was funded by Legacy Healthcare. Dr. Blume-Peytavi has received research funding and acts as an advisor to the company, among others; four of the study’s coauthors are employees of the company. Dr. Pasquali and Dr. Guttman-Yassky were not involved in the study and had no relevant financial ties to disclose.

Considerable hair regrowth can be achieved in children with alopecia areata with the use of a novel plant-based drug, according to research presented during the first late-breaking news session at the annual congress of the European Academy of Dermatology and Venereology.

In the RAAINBOW study, a greater mean relative improvement in the Severity of Alopecia Tool (SALT) scores at 24 weeks was recorded in children who had been treated topically with coacillium (22.9%) than in those who had received a topical placebo (–8.0%), with a significant 31% overall difference (P < .0001).

“Coacillium cutaneous solution was used for the first time for treatment of alopecia areata and also for the first time used in a pediatric population,” the presenting investigator Ulrike Blume-Peytavi, MD, said at the meeting.

“It’s well tolerated, and in fact what is interesting is, it has a durable response, even after treatment discontinuation,” added Dr. Blume-Peytavi, who is the deputy head of the department of dermatology, venereology and allergology at Charité-Universitätsmedizin Berlin.
 

Backing the botanical?

Paola Pasquali, MD, a dermatologist at Pius Hospital de Valls in Spain, who cochaired the session where the findings were presented, commented, “Thank you for showing that chocolate is great! I knew it. It is fantastic to see how chocolate is used.”

Dr. Pasquali was referring to the coacillium ingredient Theobroma cacao extract. The seeds of T. cacao, or the cocoa tree, are used to make various types of chocolate products. Theobroma cacao is one of four plant extracts that make up coacillium, the others being Allium cepa (onion), Citrus limon (lemon), and Paullinia cupana (guaraná, a source of caffeine).

The four plant extracts are classified as “generally regarded as safe” (GRAS), Dr. Blume-Peytavi observed, noting that the development of coacillium fell under the category of a prescription botanical drug as set out by the U.S. Food and Drug Administration or a herbal medicinal product as set out by the European Medicines Agency.

But how does it work?

The botanical’s mode of action of acting positively on hair follicle cycling and endothelial cell activation was called into question, however, by Emma Guttman-Yassky, MD, PhD, who was in the audience.

She asked, “So how do you explain that, after three large studies with topical JAK inhibitors that did not work actually in alopecia areata because it’s very hard to penetrate the scalp for a topical [drug], this one works?”

Dr. Guttman-Yassky, professor of dermatology and immunology at the Icahn School of Medicine at Mount Sinai, New York, added: “Looking at the ingredients, to me, it seems that it’s more like a DPCP [diphenylcyclopropenone]-like reaction.”

DPCP, which has been used to treat alopecia, purportedly works by stimulating the immune response to target the skin surface – causing an allergic reaction – rather than the hair follicle.

It’s an interesting question as to how a molecule penetrates the hair follicle, and it depends on the size of the molecule, Dr. Blume-Peytavi responded.

“We have done a lot of studies on follicular penetration, and we are quite aware that you need a certain size of the molecule,” she said. Between 14 and 200 nanometers appears to produce “the best penetrators,” she observed.

Dr. Blume-Peytavi commented that even after topical JAK inhibitors are applied, the molecules that penetrate do not remain in the local area for very long, yet still produce an inhibitory signaling effect.

No scalp irritation was seen in the trial, which suggests that coacillium is not working in the same way as DPCP, Dr. Blume-Peytavi countered.

The newly approved respiratory syncytial virus vaccine administered during pregnancy substantially reduces the clinical and economic burden of lower respiratory tract disease caused by RSV, according to research presented at an annual scientific meeting on infectious diseases.

“With RSV maternal vaccination that is associated with clinical efficacy of 69% against severe RSV disease at 6 months, we estimated that up to 200,000 cases can be averted, and that is associated with almost $800 million in total,” presenting author Amy W. Law, PharmD, director of global value and evidence at Pfizer, pointed out during a news briefing.

“RSV is associated with a significant burden in the U.S. and this newly approved and recommended maternal RSV vaccine can have substantial impact in easing some of that burden,” Dr. Law explained.

This study is “particularly timely as we head into RSV peak season,” said briefing moderator Natasha Halasa, MD, MPH, professor of pediatrics, division of pediatric infectious diseases at Vanderbilt University, Nashville, Tenn.

The challenge, said Dr. Halasa, is that uptake of maternal vaccines and vaccines in general is “not optimal,” making increased awareness of this new maternal RSV vaccine important.
 

Strong efficacy data

Most children are infected with RSV at least once by the time they reach age 2 years. Very young children are at particular risk of severe complications, such as pneumonia or bronchitis.

As reported previously by this news organization, in the randomized, double-blind, placebo-controlled phase 3 study, Pfizer’s maternal RSV vaccine had an almost 82% efficacy against severe RSV infection in infants from birth through the first 90 days of life.

The vaccine also had a 69% efficacy against severe disease through the first 6 months of life. As part of the trial, a total of 7,400 women received a single dose of the vaccine in the late second or third trimester of their pregnancy. There were no signs of safety issues for the mothers or infants.

Based on the results, the U.S. Food and Drug Administration approved the vaccine, known as Abrysvo, in August, to be given between weeks 32 and 36 of pregnancy.
 

New modeling study

Dr. Law and colleagues modeled the potential public health impact – both clinical and economic – of the maternal RSV vaccine among the population of all pregnant women and their infants born during a 12-month period in the United States. The model focused on severe RSV disease in babies that required medical attention.

According to their model, without widespread use of the maternal RSV vaccine, 48,246 hospitalizations, 144,495 emergency department encounters, and 399,313 outpatient clinic visits related to RSV are projected to occur annually among the U.S. birth cohort of 3.7 million infants younger than 12 months.

With widespread use of the vaccine, annual hospitalizations resulting from infant RSV would fall by 51%, emergency department encounters would decline by 32%, and outpatient clinic visits by 32% – corresponding to a decrease in direct medical costs of about $692 million and indirect nonmedical costs of roughly $110 million.

Dr. Law highlighted two important caveats to the data. “The protections are based on the year-round administration of the vaccine to pregnant women at 32 to 36 weeks’ gestational age, and this is also assuming 100% uptake. Of course, in reality, that most likely is not the case,” she told the briefing.

Dr. Halasa noted that the peak age for severe RSV illness is 3 months and it’s tough to identify infants at highest risk for severe RSV.

Nearly 80% of infants with RSV who are hospitalized do not have an underlying medical condition, “so we don’t even know who those high-risk infants are. That’s why having this vaccine is so exciting,” she told the briefing.

Dr. Halasa said it’s also important to note that infants with severe RSV typically make not just one but multiple visits to the clinic or emergency department, leading to missed days of work for the parent, not to mention the “emotional burden of having your otherwise healthy newborn or young infant in the hospital.”

In addition to Pfizer’s maternal RSV vaccine, the FDA in July approved AstraZeneca’s monoclonal antibody nirsevimab (Beyfortus) for the prevention of RSV in neonates and infants entering their first RSV season, and in children up to 24 months who remain vulnerable to severe RSV disease through their second RSV season.

The study was funded by Pfizer. Dr. Law is employed by Pfizer. Dr. Halasa has received grant and research support from Merck.

Routine screening for depression and anxiety at each primary care clinical encounter in order to meet performance metrics could compromise accuracy and clinical care, based on data from more than 380,000 individuals in primary care.

“Prioritizing repetition of intake screening questionnaires at primary care visits may have unintended consequences such as administrative burden, provision of low-value care, and reduced clinical capacity to deliver other, high-value services,” but the accuracy of workflow-based intake screening on subsequent diagnosis has not been explored, wrote Jodi Simon, DrPH, of AllianceChicago, Ill., and colleagues.

In a study published in the Annals of Family Medicine, the researchers reviewed data from screenings performed on 380,057 patients in primary care settings. They examined the accuracy and utility of the Patient Health Questionnaire (PHQ-2) for depression and the Generalized Anxiety Disorder 2 (GAD-2) for anxiety.

The data included 1,883,317 screenings with PHQ-2s and 1,573,107 with GAD-2s. Of these, 92.3% of PHQ-2 screenings and 91.4% of GAD-2 screenings indicated low likelihood of depression or anxiety (defined as cumulative scores of 0 or 1). Mean scores for the PHQ-2 and GAD-2 in the study population were 0.29 and 0.35, respectively.

In the current study, 11% of patients had positive PHQ-2 scores (defined as 2 or higher) vs. 47%-53% seen in previous studies and census data.

In an analysis of new diagnoses of depression and anxiety, the researchers found that 42.3% of patients with a new depression diagnosis were not identified on intake screening; they had scores of 0 or 1 on the PHQ-2 in the past 30 days. Similarly, 42.7% of patients with a new anxiety diagnosis had scores of 0 or 1 on the GAD-2 in the past 30 days.

In other words, “Screening only detected risk in 57.7% of patients subsequently diagnosed with depression and 57.3% of patients subsequently diagnosed with anxiety,” the researchers said. This low positivity rate in patients diagnosed within 30 days merits further research, they added.

More studies are needed, but preliminary interviews with patients, clinicians, and staff indicate that time constraints and variation in the administration of questionnaires are among the factors contributing to inaccurate screening, the researchers noted.

The current study results suggest that screenings for anxiety and depression may occur in a perfunctory or inconsistent manner that might compromise accuracy when they are part of the workflow for each clinical visit in order to meet performance metrics, they said. “Ineffective screening may unintentionally detract from clinical care because care teams and patients have less time and cognitive energy to focus on other priorities during busy clinical encounters,” they added.

Alternatively, screening for anxiety and depression at regular intervals rather than each clinical encounter could improve reliability, the researchers concluded.

The study was funded by the American Medical Association Transformation Initiative. The researchers had no financial conflicts to disclose.

Wastewater monitoring can accurately gauge influenza A and B and respiratory syncytial virus (RSV) at the population level, and help inform public response to common seasonal illnesses, according to new research reported at an annual scientific meeting on infectious diseases.

The analysis of wastewater in Calgary (Alta.) found a “positive correlation” between positivity rates for these three viruses in wastewater and weekly laboratory-confirmed clinical cases and test positivity rates, study investigator Kristine Du, with Cumming School of Medicine, University of Calgary, told this news organization.

Wastewater monitoring of viral activity has become an established tool for COVID-19 pandemic monitoring, providing a leading indicator to cases and hospitalizations. However, less is known about its potential for monitoring endemic respiratory viruses.

The new study shows that wastewater-based surveillance is a “robust and adaptable” tool for community-level surveillance of seasonal respiratory viruses – “one that can complement health care clinical testing because it’s independent from testing biases, and we can actually correlate our cases very well with it,” Ms. Du said during a preconference media briefing.
 

Tracking community trends

For the study, Ms. Du and colleagues assessed the occurrence of influenza A, influenza B, and RSV RNA in all three wastewater treatment plants in Calgary between March 2022 and April 2023 and its correlation with clinical disease.

They found that viral signals in Calgary’s wastewater for influenza A and B and RSV correlated significantly with weekly confirmed clinical cases in Calgary residents.

Influenza A peaked in Calgary’s wastewater between November and December 2022; influenza B peaked between February and April 2023; and RSV between November 2022 and February 2023.

“Wastewater gives us unbiased, objective, and comprehensive data. It can be used in addition to other testing for assessing the community burden that disease may have, and it is complementary to clinical testing,” Ms. Du said.

Their team, Ms. Du said, is continuing to proactively monitor wastewater for influenza and RSV, as well as other agents of “pandemic potential to make sure we know what could affect humans – and make sure everyone is aware of that.”

Commenting on the research, briefing moderator Belinda Ostrowsky, MD, MPH, Albert Einstein College of Medicine, New York, said, “Wastewater surveillance illustrates how understanding community levels of viral trends can identify hotspots, inform local public health decision-making, and prepare clinicians and hospitals for potential outreach. This topic is particularly timely as we head into the flu and RSV season.”

The study had no commercial funding. Ms. Du and Dr. Ostrowsky report no relevant financial relationships.

Wastewater monitoring can accurately gauge influenza A and B and respiratory syncytial virus (RSV) at the population level, and help inform public response to common seasonal illnesses, according to new research reported at an annual scientific meeting on infectious diseases.

The analysis of wastewater in Calgary (Alta.) found a “positive correlation” between positivity rates for these three viruses in wastewater and weekly laboratory-confirmed clinical cases and test positivity rates, study investigator Kristine Du, with Cumming School of Medicine, University of Calgary, told this news organization.

Wastewater monitoring of viral activity has become an established tool for COVID-19 pandemic monitoring, providing a leading indicator to cases and hospitalizations. However, less is known about its potential for monitoring endemic respiratory viruses.

The new study shows that wastewater-based surveillance is a “robust and adaptable” tool for community-level surveillance of seasonal respiratory viruses – “one that can complement health care clinical testing because it’s independent from testing biases, and we can actually correlate our cases very well with it,” Ms. Du said during a preconference media briefing.
 

Tracking community trends

For the study, Ms. Du and colleagues assessed the occurrence of influenza A, influenza B, and RSV RNA in all three wastewater treatment plants in Calgary between March 2022 and April 2023 and its correlation with clinical disease.

They found that viral signals in Calgary’s wastewater for influenza A and B and RSV correlated significantly with weekly confirmed clinical cases in Calgary residents.

Influenza A peaked in Calgary’s wastewater between November and December 2022; influenza B peaked between February and April 2023; and RSV between November 2022 and February 2023.

Atopic dermatitis (AD) is a chronic, pruritic inflammatory skin condition that typically affects the face (cheeks), neck, arms, and legs but usually spares the groin and axillary regions. AD usually starts in early infancy but also affects some adults. AD is often associated with elevated levels of immunoglobulin E (IgE). That it is the first disease to present in a series of allergic diseases – including food allergy, asthma, and allergic rhinitis, in order – and has given rise to the “atopic march” theory, which suggests that AD is part of a progression that may lead to subsequent allergic disease at other epithelial barrier surfaces.

Here are five things to know about atopic dermatitis.
 

1. Essential features of AD are pruritus and eczema

The diagnosis of AD is primarily observational. It is made on the basis of patient and family history, pattern of lesions, morphology, and clinical signs. No genetic features or biomarkers are specific enough to reliably aid in diagnosis or severity assessment. Many individual findings are used to diagnose AD, as summarized by the American Academy of Dermatology based on essential, important, associated, and exclusionary features:

• Essential features (must be present for diagnosis) are pruritus and eczema (acute, subacute, or chronic) with typical morphology and age-specific patterns and chronic or relapsing history.
• Important features (usually seen in AD and support the diagnosis) are early age of onset, atopy (personal/family history, IgE reactivity), and xerosis.
• Associated features (nonspecific but suggestive) are atypical vascular response (e.g., delayed blanch response); keratosis pilaris (and some others); ocular/periorbital changes; other regional findings (e.g., perioral changes); and perifollicular accentuation, lichenification, or prurigo lesions.
• Exclusionary conditions (must be excluded to make the AD diagnosis) are scabies, seborrheic dermatitis, contact dermatitis, ichthyoses, cutaneous T-cell lymphoma, psoriasis, photosensitivity dermatoses, immune deficiency diseases, and erythroderma due to other causes.

AD should be differentiated from other red, scaly skin conditions. It is often difficult to separate AD from seborrheic dermatitis in infancy, and the two conditions may overlap in this age group. Particularly if the condition is not responding to therapy, the diagnosis of AD should be re-reviewed and other disorders considered, including more serious nutritional, metabolic, and immunologic conditions in children and cutaneous T-cell lymphoma in adults. Allergic contact dermatitis may be both an alternative diagnosis to AD and an exacerbator of AD in some individuals.
 

2. Associated comorbidities of AD may exacerbate the condition and lead to other atopic disorders

Reported comorbidities of AD include other atopic or allergic conditions, autoimmune diseases, infections, metabolic conditions, mental health disorders, and cardiovascular disease. Certain aspects of AD, such as chronic pruritus, psychosocial distress, and inflammation, can lead to anxiety, depression, and suicidality. AD is associated with and may predispose to higher risk for other atopic disorders, including asthma, hay fever, food allergy, and eosinophilic esophagitis.

Persons with AD also appear to be at higher risk for infectious diseases. The prevalence of cutaneous and systemic infections in patients with AD is significantly higher than those without AD. Infectious complications can include skin and soft-tissue infections, bacteremia, eczema herpeticum, osteomyelitis, endocarditis, and septic arthritis.
 

3. Climate change has a profound impact on AD

The incidence of AD has increased over the past several decades, and environmental factors such as climate change have been implicated as a potential mechanism. Climate change–related factors affect the skin’s capacity to maintain homeostasis, leading to various cutaneous diseases. AD, psoriasis, pemphigus, acne vulgaris, melasma, and photoaging are all associated with rising levels of air pollution. Elevated temperatures due to global warming induce disruption of the skin microbiome, thereby affecting AD.

Extreme weather events due to climate change, including floods and wildfires, are implicated in cutaneous injuries, skin infections, and acute worsening of inflammatory skin disorders.
 

4. The impact and appearance of AD varies in different racial groups

It was once believed that AD was just one single disease affecting people of many different races. More recently, it has been proposed that AD is in fact a group of different diseases. Both epidemiologic and genetic factors may play a role in influencing the main features of AD.

Spongiotic processes such as AD that would be pink or erythematous on white skin are often hypopigmented in individuals with darkly pigmented skin. AD has a higher prevalence and severity in Black and mixed-race populations, probably owing to a combination of environmental and intrinsic factors. Black skin has been shown to have increased transepidermal water loss and lower levels of ceramides, which are important components of the lipid barrier in the stratum corneum.

The American College of Allergy, Asthma & Immunology, along with the Allergy & Asthma Network, are partnering to create Eczema in Skin of Color, a website to aid physicians and patients in recognizing eczema in people with all skin types.
 

5. New and emerging therapies are poised to improve outcomes with AD treatment

Ruxolitinib cream, a topical Janus kinase (JAK)-1/JAK2 inhibitor, was approved for AD by the U.S. Food and Drug Administration in September 2021. The approval was based on results from the Topical Ruxolitinib Evaluation in AD (TRuE-AD) clinical trial program, which consisted of phase 3 studies that investigated 1,249 patients aged greater than or equal to 12 years with mild to moderate AD (Investigator’s Global Assessment score of 2-3) with a body surface area of 3%-20% (excluding scalp). The 2023 AAD guidelines for topical treatment recommend ruxolitinib cream for adults with mild to moderate AD.

Tralokinumab is a monoclonal antibody that inhibits the interleukin-13 cytokines, which prevents the release of cytokines, chemokines, and IgE. It was approved by the FDA in 2021 for treatment of moderate to severe AD. It is administered by subcutaneous injection every 2 weeks. Approval was based on the phase 3 trials ECZTRA 1, 2, and 3, which assessed the efficacy of tralokinumab in 1,934 adults.

Abrocitinib is an oral, once-daily JAK1 inhibitor for treatment of adults living with refractory, moderate to severe AD. FDA approval was based on results of five clinical trials from a large-scale trial program of more than 1,600 patients. Across the trials, abrocitinib demonstrated a consistent safety profile and profound improvements in skin clearance, extent of disease, and severity, as well as rapid improvement in itch after 2 weeks, for some people living with AD vs placebo.

Upadacitinib, another oral JAK1 inhibitor, was approved by the FDA in January 2022 for refractory moderate to severe AD. Approval was based on three double-blind phase 3 trials (Measure Up 1, Measure Up 2, AD Up) in which 2,584 patients with moderate to severe AD were randomized to receive oral upadacitinib 15 mg/d and 30 mg/d. In Measure Up 1 and Measure Up 2, upadacitinib was evaluated as monotherapy; in AD Up, upadacitinib was evaluated in combination with topical corticosteroids.
 

On the horizon

Baricitinib, an oral JAK1/2 inhibitor, is not yet approved by the FDA for AD. It is, however, approved for moderate to severe AD treatment in the European Union and many other countries. A 2022 review of studies evaluating baricitinib for the treatment of moderate to severe AD in adults (BREEZE-AD1, -AD2, -AD3, -AD4, -AD5, -AD6) reported that current evidence supports baricitinib, used as monotherapy or in combination with topical corticosteroids, as a safe and effective agent that can be used as an alternative to subcutaneous biologics in adults with moderate to severe AD.

Topical JAK inhibitors

A 2023 systematic review (19 studies, 3,600 participants) reported on several topical JAK inhibitors that are effective for treating AD. It suggests a stronger safety profile and better results, compared with systemic JAK inhibitors. The review focused on topical delgocitinib, tofacitinib, ruxolitinib, cerdulatinib, and ifidancitinib. All agents were effective in treating AD. All of these topical JAK inhibitors had minimal risk for mild to moderate adverse effects.

Biologics

Lebrikizumab was evaluated in a phase 2b, double-blind, placebo-controlled randomized clinical trial. After 16 weeks (280 participants), patients with moderate to severe AD showed a dose-dependent significant improvement in the primary endpoint, compared with placebo. Two phase 3 trials (ADvocate1, ADvocate2) evaluated the safety and efficacy of monotherapy with lebrikizumab in adults and adolescents with moderate to severe AD.

Nemolizumab, assessed in long-term phase 3 trials of AD-associated pruritus, resulted in clinically meaningful improvements from the beginning of treatment to week 68. Nemolizumab is being evaluated in two identical phase 3 studies (Arcadia 1, Arcadia 2) and a long-term extension study.

New guidelines on determining brain death offer the first updated recommendations in more than a decade for adult and pediatric patients.

The consensus practice guideline on brain death, also known as death by neurologic criteria (BD/DNC), was developed by a panel of 20 experts from different specialties, institutions, and medical societies.

As with previous guidelines, the updated version stipulates that brain death should be declared when a patient with a known cause of catastrophic brain injury has permanent loss of function of the brain, including the brain stem, which results in coma, brain stem areflexia, and apnea in the setting of an adequate stimulus.

But the updated version also clarifies questions on neurological examinations and apnea testing and offers new guidance on pre-evaluation targets for blood pressure and body temperature and evaluating brain death in patients who are pregnant, are on extracorporeal membrane oxygenation, or have an injury to the base of the brain.

Also, for the first time, the guidance clarifies that clinicians don’t need to obtain consent before performing a brain death evaluation, unless institutional policy, state laws, or regulations stipulate otherwise.

“The 2023 guidelines will be considered the standard of care in the U.S.,” lead author David M. Greer, MD, chair and chief of neurology, Boston University, and chief of neurology, Boston Medical Center, said in an interview. “Each hospital in the U.S. is responsible for its own policy for BD/DNC determination, and our hope is that they will quickly revise their policies in accordance with this new national standard.”

The guidelines, which are accompanied by a three-page checklist and a free digital app, were published online in Neurology.
 

Four years in the making

Work on the 85 recommendations in the new report began more than 4 years ago as a collaborative effort by the American Academy of Neurology, the American Academy of Pediatrics, the Child Neurology Society, and the Society of Critical Care Medicine.

A lack of high-quality evidence on brain death determination led panelists to devise an evidence-informed formal consensus process to develop the guidelines, which involved three rounds of anonymous voting on each recommendation and the rationales behind them.

The strength of each recommendation was based on the level of consensus reached through voting, with Level A denoting a recommendation that “must” be followed, Level B one that “should” be followed, and Level C one that “may” be followed.

The majority of recommendations received an A or B rating. Only one recommendation, about whether a second clinical exam is needed in adults, garnered a C rating.

In children, the guidelines recommend that clinicians must perform two clinical examinations and two apnea tests 12 hours apart. In adults, only one exam is required. Both of those recommendations were rated Level A. A recommendation for a second exam in adults received the single Level C rating.
 

A uniform set of guidelines?

The new guidelines replace adult practice guidance published by AAN in 2010 and guideline for infants and children released in 2011 by AAP, CNS, and SCCM, and for the first time combine brain death guidelines for adult and pediatric patients into one document.

“It is important for clinicians to review the new guideline carefully and ensure their hospital brain death guidelines are updated to be consistent with the new guideline in order to prevent inaccurate determinations of death,” guidelines coauthor Ariane Lewis, MD, NYU Langone Health, New York, said in an interview.

The 1981 Uniform Determination of Death Act (UDDA) is the legal foundation for the declaration of BD/DNC in the United States, but it only stipulates that brain death determination must be made in accordance with accepted medical standards.

There is no single national standard, and states and hospitals are free to adopt their own, which many have done. One goal of the new guidelines was to create a uniform set of guidelines that all institutions follow.

“This is a step toward having a set of guidelines that are accepted by most of the societies and clinical specialties involved in this sort of diagnosis,” that could lead to a national-level policy, Fernando Goldenberg, MD, professor of neurology and director of neuroscience critical care, University of Chicago Medicine, said in an interview.

Dr. Goldenberg was not part of the panel that developed the updated guidelines, but was a coauthor of a consensus statement from the World Brain Death Project in 2020.

Developing a singular global guideline for brain death determination is unlikely, Dr. Goldenberg said. Policies vary widely across the world, and some countries don’t even recognize brain death.

“But this attempts to unify things at the U.S. level, which is very important,” he said.
 

Permanent vs. irreversible

Dr. Goldenberg said that combining adult and pediatric guidelines into one document will be very helpful for clinicians like him who treat patients from age 16 years and up.

The expanded guidance on apnea testing, recommendations on specific ancillary tests to use or avoid, and inclusion of language stipulating that prior consent is not needed to perform a brain death evaluation are also useful.

He also noted that the section on credentialing and training of clinicians who perform BD/DNC evaluations recognizes advanced practice providers, the first time he recalls seeing these professionals included in brain death guidelines.

However, the panel’s decision to use the term “permanent” to describe loss of brain function instead of “irreversible” gave Dr. Goldenberg pause.

The UDDA provides that an individual is declared legally dead when “circulatory and respiratory functions irreversibly stop; or all functions of the entire brain, including the brain stem, irreversibly stop.”

Earlier in October, the American College of Physicians released a position paper on cardiorespiratory death determination that called for a revision of the UDDA language.

The ACP suggested that “irreversibly” be replaced with “permanently” with regard to the cessation of circulatory and respiratory functions, but that “irreversible” be kept in the description of brain death.

“Permanent means that there is damage that is potentially reversible and irreversible means that the damage is so profound, it cannot be reversed even if an attempt to do so is performed,” Dr. Goldenberg said.

Even though the World Brain Death Project, on which he worked, also used “permanent” to describe brain function loss, Dr. Goldenberg said he aligns with ACP’s position.

“The understanding of brain death is that the damage is so profound, it is irreversible, even if you were to try,” he said. “Therefore, I think that the most appropriate term for brain death should be irreversible as opposed to permanent.”

New guidelines on determining brain death offer the first updated recommendations in more than a decade for adult and pediatric patients.

The consensus practice guideline on brain death, also known as death by neurologic criteria (BD/DNC), was developed by a panel of 20 experts from different specialties, institutions, and medical societies.

TOPLINE:

Noninvasive three-dimensional (3D) stereophotogrammetry may be a valuable adjunctive tool to detect progression of craniofacial morphea (CM) over time.

METHODOLOGY:

• Existing tools that detect disease progression in patients with CM are limited.
• In a prospective cohort study, researchers evaluated the use of 3-D stereophotogrammetry, a noninvasive, radiation-free imaging modality, to detect disease progression in 27 consecutive patients with CM seen at Boston Children’s Hospital and Brigham and Women’s Hospital from April 1, 2019, to March 1, 2023.
• After clinical and 3-D stereophotogrammetry assessments were performed at 2- to 12-month intervals, the 3-D images were rated by an expert (a board-certified plastic craniofacial surgeon) and a nonexpert (a board-certified dermatologist) as demonstrating progression or no progression.
• Kappa coefficients were used to calculate inter-rater reliability.

TAKEAWAY:

• Most of the study participants (73%) were female, their median age was 14 years (range, 5-40 years), and each underwent 3-D stereophotogrammetry imaging at least two times spaced a median of 3 months apart.
• On the basis of clinical assessments during the 48-month study period, 10 patients (37%) experienced progression of their disease.
• 3-D stereophotogrammetry not only corroborated clinical impressions of disease progression with strong inter-rater reliability (kappa = 0.80; 95% confidence interval, 0.61-0.99), but it also detected occult progression of asymmetry not noted on clinical examination in three additional patients.
• In subgroup analyses, assessment of 3-D images demonstrated substantial to near-perfect inter-rater reliability in patients with Fitzpatrick skin types IV-VI.

IN PRACTICE:

“Further work is necessary to validate this measure in a larger cohort and to guide its incorporation into medical decision-making for patients with CM,” the researchers wrote.

SOURCE:

Katharina S. Shaw, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, led the research. The study was published online in JAMA Dermatology.

LIMITATIONS:

The sample was small, and a criterion standard for assessing CM was lacking.

DISCLOSURES:

The researchers reported having no relevant conflicts of interest.

In the first study evaluating pediatric sleep-disordered breathing (SDB) from both indoor environment and neighborhood perspectives, multilevel risk factors were revealed as being associated with SDB-related symptoms. Beyond known associations with environmental tobacco smoke (ETS), a novel association with SDB symptoms was observed for exposure to indoor pests such as mice, cockroaches, and rats.

Although it has been well known that pediatric SDB affects low socioeconomic status (SES) children disproportionately, the roles of multilevel risk factor drivers including individual health, household SES, indoor exposures to environmental tobacco smoke, pests, and neighborhood characteristics have not been well studied, Gueye-Ndiaye et al. wrote in CHEST Pulmonary.

Pediatric SDB, a known risk factor for many health, neurobehavioral, and functional outcomes, includes habitual snoring and obstructive sleep apnea and may contribute to health disparities. Adenotonsillar hypertrophy and obesity are the most commonly recognized risk factors for SDB in generally healthy school-aged children. A role for other risk factors, however, is suggested by the fact that Black children have a fourfold increased risk for obstructive sleep apnea (OSA), compared with White children, unexplained by obesity, and have decreased response to treatment of OSA with adenotonsillectomy, compared with White children. Several studies point in the direction of neighborhood disadvantages as factors in heightened SDB prevalence or severity, Gueye-Ndiaye et al. stated.

The authors performed cross-sectional analyses on data recorded from 303 children (aged 6-12 years) enrolled in the Environmental Assessment of Sleep Youth (EASY) study from 2018 to 2022. Among them, 39% were Hispanic, Latino, Latina, or Spanish origin, 30% were Black or African American, 22% were White, and 11% were other. Maternal education attainment of a high school diploma or less was reported in 27%, and 65% of the sample lived in disadvantaged neighborhoods. Twenty-eight percent of children met criteria for objective SDB (Apnea-Hypopnea Index/Oxygen Desaturation Index ≥ 5/hr). Exposure documentation was informed by caregiver reports, assays of measured settled dust from the child’s bedroom, and neighborhood-level census data from which the Childhood Opportunity Index characterizing neighborhood disadvantage (ND) was derived. The study primary outcome was the SDB-related symptom burden assessed by the OSA-18 questionnaire total score.

Compared with children with no adverse indoor exposures to ETS and pests, children with such exposures had an approximately 4-12 point increase in total OSA-18 scores, and the increase among those with exposure to both ETS and pests was about 20 points (approximately a 1.3 standard deviation increase), Gueye-Ndiaye et al. reported.

In models adjusted for age, sex, minority race, and ethnicity, low maternal education was associated with a 7.55 (95% confidence interval, 3.44-11.66; P < .01) increased OSA-18 score. In models adjusted for sociodemographics including maternal education, history of asthma and allergic rhinitis were associated with a 13.63 (95% CI, 9.44-17.82; P < .01) and a 6.95 (95% CI, 2.62-11.29; P < .02) increased OSA-18 score, respectively. The authors noted that prior Canadian studies have shown OSA to be three times as likely in children with mothers reporting less than a high school education than in children with university educated mothers.

Speculating on the drivers of this association, they noted that the poor air quality due to tobacco smoke and allergen exposures to rodents, mold, and cockroaches are known contributors to asthma symptoms. Despite the differing pathogenesis of OSA and asthma, they suggest overlapping risk factors. Irritants and allergens may exacerbate SDB by stimulating immune responses manifested as adenotonsillar hypertrophy and by amplifying nasopharyngeal inflammation, adversely affecting upper airway patency. While ETS was not common in the sample, it was associated strongly with SDB. Gueye-Ndiaye et al. also showed associations between pest exposure, bedroom dust, and SDB symptoms. The findings, they concluded, support the importance of household- and bedroom-environmental conditions and sleep health.

OSA-18 scores were also elevated by about 7-14 points with allergic rhinitis and asthma, respectively. The findings, Gueye-Ndiaye et al. stated, underscore that asthma prevention strategies can be leveraged to address SDB disparities. No amplification of pest exposure effects, however, was found for asthma or allergic rhinitis.

“This is an incredibly important study, one that adds to our understanding of the risk factors that contribute to pediatric sleep health disparities,” said assistant professor of pediatrics Anne C. Coates, MD, Tufts University, Boston. “We have previously understood risk factors for sleep-disordered breathing like adenotonsillar hypertrophy, but this adds other elements like environmental tobacco smoke, pests, and home and neighborhood factors,” she told this news organization. “One of the most important takeaways is that beyond the importance of accurate diagnosis, there is the importance of advocating for our patients to ensure that they have the healthiest homes and neighborhoods. We need to inspire our colleagues to be advocates – for example – for pest mitigation, for antismoking policies, for every policy preventing the factors that contribute to the burden of disease.”

Dr. Coates is coauthor of “Advocacy and Health Equity: The Role of the Pediatric Pulmonologist,” currently in press (Clinics in Chest Medicine), and a member of the CHEST Physician Editorial Board.

The authors noted that a study limitation was that the sample was from one geographic area (Boston). Neither the authors nor Dr. Coates listed any conflicts.

Compared with children with no adverse indoor exposures to ETS and pests, children with such exposures had an approximately 4-12 point increase in total OSA-18 scores, and the increase among those with exposure to both ETS and pests was about 20 points (approximately a 1.3 standard deviation increase), Gueye-Ndiaye et al. reported.

In models adjusted for age, sex, minority race, and ethnicity, low maternal education was associated with a 7.55 (95% confidence interval, 3.44-11.66; P < .01) increased OSA-18 score. In models adjusted for sociodemographics including maternal education, history of asthma and allergic rhinitis were associated with a 13.63 (95% CI, 9.44-17.82; P < .01) and a 6.95 (95% CI, 2.62-11.29; P < .02) increased OSA-18 score, respectively. The authors noted that prior Canadian studies have shown OSA to be three times as likely in children with mothers reporting less than a high school education than in children with university educated mothers.

Speculating on the drivers of this association, they noted that the poor air quality due to tobacco smoke and allergen exposures to rodents, mold, and cockroaches are known contributors to asthma symptoms. Despite the differing pathogenesis of OSA and asthma, they suggest overlapping risk factors. Irritants and allergens may exacerbate SDB by stimulating immune responses manifested as adenotonsillar hypertrophy and by amplifying nasopharyngeal inflammation, adversely affecting upper airway patency. While ETS was not common in the sample, it was associated strongly with SDB. Gueye-Ndiaye et al. also showed associations between pest exposure, bedroom dust, and SDB symptoms. The findings, they concluded, support the importance of household- and bedroom-environmental conditions and sleep health.

OSA-18 scores were also elevated by about 7-14 points with allergic rhinitis and asthma, respectively. The findings, Gueye-Ndiaye et al. stated, underscore that asthma prevention strategies can be leveraged to address SDB disparities. No amplification of pest exposure effects, however, was found for asthma or allergic rhinitis.

“This is an incredibly important study, one that adds to our understanding of the risk factors that contribute to pediatric sleep health disparities,” said assistant professor of pediatrics Anne C. Coates, MD, Tufts University, Boston. “We have previously understood risk factors for sleep-disordered breathing like adenotonsillar hypertrophy, but this adds other elements like environmental tobacco smoke, pests, and home and neighborhood factors,” she told this news organization. “One of the most important takeaways is that beyond the importance of accurate diagnosis, there is the importance of advocating for our patients to ensure that they have the healthiest homes and neighborhoods. We need to inspire our colleagues to be advocates – for example – for pest mitigation, for antismoking policies, for every policy preventing the factors that contribute to the burden of disease.”

In the first study evaluating pediatric sleep-disordered breathing (SDB) from both indoor environment and neighborhood perspectives, multilevel risk factors were revealed as being associated with SDB-related symptoms. Beyond known associations with environmental tobacco smoke (ETS), a novel association with SDB symptoms was observed for exposure to indoor pests such as mice, cockroaches, and rats.

Although it has been well known that pediatric SDB affects low socioeconomic status (SES) children disproportionately, the roles of multilevel risk factor drivers including individual health, household SES, indoor exposures to environmental tobacco smoke, pests, and neighborhood characteristics have not been well studied, Gueye-Ndiaye et al. wrote in CHEST Pulmonary.

Pediatric SDB, a known risk factor for many health, neurobehavioral, and functional outcomes, includes habitual snoring and obstructive sleep apnea and may contribute to health disparities. Adenotonsillar hypertrophy and obesity are the most commonly recognized risk factors for SDB in generally healthy school-aged children. A role for other risk factors, however, is suggested by the fact that Black children have a fourfold increased risk for obstructive sleep apnea (OSA), compared with White children, unexplained by obesity, and have decreased response to treatment of OSA with adenotonsillectomy, compared with White children. Several studies point in the direction of neighborhood disadvantages as factors in heightened SDB prevalence or severity, Gueye-Ndiaye et al. stated.

The authors performed cross-sectional analyses on data recorded from 303 children (aged 6-12 years) enrolled in the Environmental Assessment of Sleep Youth (EASY) study from 2018 to 2022. Among them, 39% were Hispanic, Latino, Latina, or Spanish origin, 30% were Black or African American, 22% were White, and 11% were other. Maternal education attainment of a high school diploma or less was reported in 27%, and 65% of the sample lived in disadvantaged neighborhoods. Twenty-eight percent of children met criteria for objective SDB (Apnea-Hypopnea Index/Oxygen Desaturation Index ≥ 5/hr). Exposure documentation was informed by caregiver reports, assays of measured settled dust from the child’s bedroom, and neighborhood-level census data from which the Childhood Opportunity Index characterizing neighborhood disadvantage (ND) was derived. The study primary outcome was the SDB-related symptom burden assessed by the OSA-18 questionnaire total score.
