Semaglutide (Ozempic, Novo Nordisk) is associated with a significantly lower risk for overdose in individuals with opioid use disorder (OUD), new research shows.

The findings suggest that the drug may be a promising treatment option for OUD, adding to the growing evidence of the potential psychiatric benefits of glucagon-like peptide 1 (GLP-1) inhibitors.

“Our study provided real-world evidence suggesting that semaglutide could have benefits in preventing opioid overdose and treating opioid use disorder,” co–lead author Rong Xu, PhD, director of the Center for Artificial Intelligence in Drug Discovery at Case Western Reserve University School of Medicine, Cleveland, Ohio, said in an interview.

However, Xu cautioned that this evidence is preliminary and randomized clinical trials are required to confirm these findings.

The study published online in a research letter on September 25 in JAMA Network Open.
 

New Addiction Meds an Urgent Priority

Investigators analyzed electronic medical records from 33,006 patients with type 2 diabetes and OUD who were prescribed one of eight antidiabetic medications between 2017 and 2023. 

Drugs included in the study were semaglutide, insulin, metformin, albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, dipeptidyl peptidase–4 inhibitors, sodium-glucose cotransporter-2 inhibitors, sulfonylureas, and thiazolidinediones. 

Participants in the semaglutide and each comparison group were matched for certain covariates at baseline, such as socioeconomic status and OUD medications. 

After 1 year, semaglutide was associated with a 42%-68% lower risk for opioid overdose than other antidiabetic medications, including other GLP-1s (range of hazard ratio [HR]: HR, 0.32; 95% CI, 0.12-0.89; to HR, 0.58; 95%CI, 0.38-0.87). 

Xu noted a number of study limitations including the effect of possible confounders and sole reliance on prescription data.

However, the findings are in line with those of prior studies showing that semaglutide may be associated with lower rates of alcohol and nicotine use, she said. 

Earlier this year, Xu, along with National Institute on Drug Abuse Director Nora Volkow, MD, and colleagues, published a retrospective cohort study of nearly 84,000 patients with obesity. That analysis showed that semaglutide was associated with a significantly lower risk of new alcohol use disorder diagnoses. 

In a previous editorial by Xu and Volkow that summarized the research to-date on GLP-1s for nicotine, alcohol, and substance use disorders, they note that “closing the addiction treatment gap and discovering new, more effective addiction medications are urgent priorities. In this regard, investigating the potential of GLP-1 analogue medications to treat substance use disorder deserves fast and rigorous testing.”
 

Caution Warranted

Commenting on the study, Riccardo De Giorgi, MD, PhD, department of psychiatry, University of Oxford in England, said at this point, “we have to be very careful about how we interpret these data.” 

In August, De Giorgi published a study showing that semaglutide was associated with reduced risk for several neurologic and psychiatric outcomes including dementia and nicotine misuse. 

While there is enough observational evidence linking GLP-1 medications with reduced SUD risk, he noted that “now is the time to move on and conduct some randomized clinical trials, specifically testing our hypothesis in people who have psychiatric disorders.”

De Giorgi also called for mechanistic studies of semaglutide and other so that researchers could learn more about how it works to reduce cravings. “Instead of going from bench to bed, we need to go back to the bench,” he said.

As previously reported, De Giorgi recently called on experts in the field to actively explore the potential of GLP-1 inhibitors for mental illness. 

The study was funded by National Institute on Alcohol Abuse and Alcoholism, National Institute on Aging, the National Center for Advancing Translational Sciences, and the Intramural Research Program of the National Institutes of Health. Xu reported no relevant financial relationships. De Giorgi reported receiving funding from the National Institute for Health Research Oxford Health Biomedical Research Centre.

It’s critical to bring the voice of gastroenterology to Capitol Hill to make a real difference in legislation that affects patient care. That’s why we gathered our leaders from across the United States in Washington, DC, to meet with congressional offices during our annual Advocacy Day.

GIs from California to Massachusetts and many states in between met with House and Senate offices to educate members of Congress and their staff about the most critical policy issues impacting you and your patients. In total, 28 states were represented and we attended more than 100 meetings in 64 different districts, which was a mix of both Republican and Democratic offices.

University of Miami

For the second year in a row, we were fortunate to be joined by GI patient advocates as well, who shared personal stories about the challenges they encountered in the health care system, and the negative effects to their well-being and quality of life because of red tape caused by prior authorization and step therapy.

The in-person advocacy of our members and patient advocates makes a difference. In one of AGA President Dr. Maria Abreu’s meetings, the congressional staffer remembered that he met with her, Dr. Mel Wilcox, and a patient advocate during 2023’s Advocacy Day and recounted the impact of their conversation about delays to timely access to care for inflammatory bowel disease medication.

Numerous GIs had similar experiences on Advocacy Day and recounted the benefits of being able to walk into House and Senate offices and educate congressional staff on the issues they’re experiencing in their clinic or lab.

Being able to start these conversations about health care and GI and build these relationships showcases the value of Advocacy Day, and demonstrates how AGA works with members to make it easy to advocate for the issues important to them. We were able to have a full day of constructive meetings with lawmakers and their staff thanks to members and patient advocates. Thank you for being engaged and using your voices to protect GI patient care!

VIENNA — Artificial Intelligence (AI) can assist doctors in assessing and diagnosing respiratory illnesses in infants and children, according to two new studies presented at the European Respiratory Society (ERS) 2024 Congress.

Researchers can train artificial neural networks (ANNs) to detect lung disease in premature babies by analyzing their breathing patterns while they sleep. “Our noninvasive test is less distressing for the baby and their parents, meaning they can access treatment more quickly, and may also be relevant for their long-term prognosis,” said Edgar Delgado-Eckert, PhD, adjunct professor in the Department of Biomedical Engineering at The University of Basel, Switzerland, and a research group leader at the University Children’s Hospital, Switzerland.

Manjith Narayanan, MD, a consultant in pediatric pulmonology at the Royal Hospital for Children and Young People, Edinburgh, and honorary senior clinical lecturer at The University of Edinburgh, United Kingdom, said chatbots such as ChatGPT, Bard, and Bing can perform as well as or better than trainee doctors when assessing children with respiratory issues. He said chatbots could triage patients more quickly and ease pressure on health services.
 

Chatbots Show Promise in Triage of Pediatric Respiratory Illnesses

Researchers at The University of Edinburgh provided 10 trainee doctors with less than 4 months of clinical experience in pediatrics with clinical scenarios that covered topics such as cystic fibrosis, asthma, sleep-disordered breathing, breathlessness, chest infections, or no obvious diagnosis. 

The trainee doctors had 1 hour to use the internet, although they were not allowed to use chatbots to solve each scenario with a descriptive answer. 

Each scenario was also presented to the three large language models (LLMs): OpenAI’s ChatGPT, Google’s Bard, and Microsoft’s Bing.

Six pediatric respiratory experts assessed all responses, scoring correctness, comprehensiveness, usefulness, plausibility, and coherence on a scale of 0-9. They were also asked to say whether they thought a human or a chatbot generated each response.

ChatGPT scored an average of 7 out of 9 overall and was believed to be more human-like than responses from the other chatbots. Bard scored an average of 6 out of 9 and was more “coherent” than trainee doctors, but in other respects, it was no better or worse than trainee doctors. Bing and trainee doctors scored an average of 4 out of 9. The six pediatricians reliably identified Bing and Bard’s responses as nonhuman.

“Our study is the first, to our knowledge, to test LLMs against trainee doctors in situations that reflect real-life clinical practice,” Narayanan said. “We did this by allowing the trainee doctors to have full access to resources available on the internet, as they would in real life. This moves the focus away from testing memory, where LLMs have a clear advantage.”

Narayanan said that these models could help nurses, trainee doctors, and primary care physicians triage patients quickly and assist medical professionals in their studies by summarizing their thought processes. “The key word, though, is “assist.” They cannot replace conventional medical training yet,” he told Medscape Medical News. 

The researchers found no obvious hallucinations — seemingly made-up information — with any of the three LLMs. Still, Narayanan said, “We need to be aware of this possibility and build mitigations.”

Hilary Pinnock, ERS education council chair and professor of primary care respiratory medicine at The University of Edinburgh who was not involved in the research, said seeing how widely available AI tools can provide solutions to complex cases of respiratory illness in children is exciting and worrying at the same time. “It certainly points the way to a brave new world of AI-supported care.” 

“However, before we start to use AI in routine clinical practice, we need to be confident that it will not create errors either through ‘hallucinating’ fake information or because it has been trained on data that does not equitably represent the population we serve,” she said.
 

AI Predicts Lung Disease in Premature Babies

Identifying bronchopulmonary dysplasia (BPD) in premature babies remains a challenge. Lung function tests usually require blowing out on request, which is a task babies cannot perform. Current techniques require sophisticated equipment to measure an infant’s lung ventilation characteristics, so doctors usually diagnose BPD by the presence of its leading causes, prematurity and the need for respiratory support.

Researchers at the University of Basel in Switzerland trained an ANN model to predict BPD in premature babies.

The team studied a group of 139 full-term and 190 premature infants who had been assessed for BPD, recording their breathing for 10 minutes while they slept. For each baby, 100 consecutive regular breaths, carefully inspected to exclude sighs or other artifacts, were used to train, validate, and test an ANN called a Long Short-Term Memory model (LSTM), which is particularly effective at classifying sequential data such as tidal breathing.

Researchers used 60% of the data to teach the network how to recognize BPD, 20% to validate the model, and then fed the remaining 20% of the data to the model to see if it could correctly identify those babies with BPD.

The LSTM model classified a series of flow values in the unseen test data set as belonging to a patient diagnosed with BPD or not with 96% accuracy.

“Until recently, this need for large amounts of data has hindered efforts to create accurate models for lung disease in infants because it is so difficult to assess their lung function,” Delgado-Eckert said. “Our research delivers, for the first time, a comprehensive way of analyzing infants’ breathing and allows us to detect which babies have BPD as early as 1 month of corrected age.”

The study presented by Delgado-Eckert received funding from the Swiss National Science Foundation. Narayanan and Pinnock reported no relevant financial relationships.

Manjith Narayanan, MD, a consultant in pediatric pulmonology at the Royal Hospital for Children and Young People, Edinburgh, and honorary senior clinical lecturer at The University of Edinburgh, United Kingdom, said chatbots such as ChatGPT, Bard, and Bing can perform as well as or better than trainee doctors when assessing children with respiratory issues. He said chatbots could triage patients more quickly and ease pressure on health services.
 

Chatbots Show Promise in Triage of Pediatric Respiratory Illnesses

Researchers at The University of Edinburgh provided 10 trainee doctors with less than 4 months of clinical experience in pediatrics with clinical scenarios that covered topics such as cystic fibrosis, asthma, sleep-disordered breathing, breathlessness, chest infections, or no obvious diagnosis. 

The trainee doctors had 1 hour to use the internet, although they were not allowed to use chatbots to solve each scenario with a descriptive answer. 

Each scenario was also presented to the three large language models (LLMs): OpenAI’s ChatGPT, Google’s Bard, and Microsoft’s Bing.

Six pediatric respiratory experts assessed all responses, scoring correctness, comprehensiveness, usefulness, plausibility, and coherence on a scale of 0-9. They were also asked to say whether they thought a human or a chatbot generated each response.

ChatGPT scored an average of 7 out of 9 overall and was believed to be more human-like than responses from the other chatbots. Bard scored an average of 6 out of 9 and was more “coherent” than trainee doctors, but in other respects, it was no better or worse than trainee doctors. Bing and trainee doctors scored an average of 4 out of 9. The six pediatricians reliably identified Bing and Bard’s responses as nonhuman.

“Our study is the first, to our knowledge, to test LLMs against trainee doctors in situations that reflect real-life clinical practice,” Narayanan said. “We did this by allowing the trainee doctors to have full access to resources available on the internet, as they would in real life. This moves the focus away from testing memory, where LLMs have a clear advantage.”

Narayanan said that these models could help nurses, trainee doctors, and primary care physicians triage patients quickly and assist medical professionals in their studies by summarizing their thought processes. “The key word, though, is “assist.” They cannot replace conventional medical training yet,” he told Medscape Medical News. 

The researchers found no obvious hallucinations — seemingly made-up information — with any of the three LLMs. Still, Narayanan said, “We need to be aware of this possibility and build mitigations.”

Hilary Pinnock, ERS education council chair and professor of primary care respiratory medicine at The University of Edinburgh who was not involved in the research, said seeing how widely available AI tools can provide solutions to complex cases of respiratory illness in children is exciting and worrying at the same time. “It certainly points the way to a brave new world of AI-supported care.” 

“However, before we start to use AI in routine clinical practice, we need to be confident that it will not create errors either through ‘hallucinating’ fake information or because it has been trained on data that does not equitably represent the population we serve,” she said.
 

AI Predicts Lung Disease in Premature Babies

Identifying bronchopulmonary dysplasia (BPD) in premature babies remains a challenge. Lung function tests usually require blowing out on request, which is a task babies cannot perform. Current techniques require sophisticated equipment to measure an infant’s lung ventilation characteristics, so doctors usually diagnose BPD by the presence of its leading causes, prematurity and the need for respiratory support.

Researchers at the University of Basel in Switzerland trained an ANN model to predict BPD in premature babies.

The team studied a group of 139 full-term and 190 premature infants who had been assessed for BPD, recording their breathing for 10 minutes while they slept. For each baby, 100 consecutive regular breaths, carefully inspected to exclude sighs or other artifacts, were used to train, validate, and test an ANN called a Long Short-Term Memory model (LSTM), which is particularly effective at classifying sequential data such as tidal breathing.

Researchers used 60% of the data to teach the network how to recognize BPD, 20% to validate the model, and then fed the remaining 20% of the data to the model to see if it could correctly identify those babies with BPD.

The LSTM model classified a series of flow values in the unseen test data set as belonging to a patient diagnosed with BPD or not with 96% accuracy.

“Until recently, this need for large amounts of data has hindered efforts to create accurate models for lung disease in infants because it is so difficult to assess their lung function,” Delgado-Eckert said. “Our research delivers, for the first time, a comprehensive way of analyzing infants’ breathing and allows us to detect which babies have BPD as early as 1 month of corrected age.”

The study presented by Delgado-Eckert received funding from the Swiss National Science Foundation. Narayanan and Pinnock reported no relevant financial relationships.

ORLANDO — It’s important for pediatricians not only to understand the causes and effects of climate change but also to know how to discuss this issue with families and make risk-based adjustments to their clinical practice based on the individual health and circumstances of each patient. That’s one of the key messages delivered at the annual meeting of the American Academy of Pediatrics (AAP) by Elizabeth C. Matsui, MD, MHS, professor of population health and pediatrics and director of the Center for Health and Environment Education and Research at the University of Texas at Austin Dell Medical School. 

“Even though climate change has been here and has been affecting health already for a while, it’s just really impossible to ignore right now,” she told attendees in a session focused on climate change impacts on allergies and asthma. “The challenge is connecting the dots between something that is much larger, or feels much larger, than the patient and the family that’s in front of you.” 

The reality, however, is that climate change is now impacting patients’ health on an individual level, and pediatricians have a responsibility to understand how that’s happening and to help their families prepare for it. 

“From the perspective of someone who went into medicine to practice and take care of the individual patient, I think it has been more difficult to connect those dots, and for the people in this room, it’s our job to connect those dots,” Matsui said. She also acknowledged that many of the solutions are frustratingly limited to the policy level and challenging to implement, “but it doesn’t mean that we can’t make a difference for the patients who are in front of us.” 

Charles Moon, MD, a pediatrician and Pediatric Environmental Health Fellow at the Children’s Environmental Health Center, Icahn School of Medicine at Mount Sinai, New York City, found the talk particularly helpful in providing information about both the broader issue and what it means on a local practice level. 

“The biggest takeaway is that more people and more pediatricians are tuning in to this issue and realizing the dangers,” Moon said. “It’s clear that a larger community is forming around this, and I think we are at the cusp where more and more people will be coming in. We are really focusing on taking all the data and trying to figure out solutions. I think the solutions orientation is the most important part.” 
 

Understanding the Big Picture

Matsui opened with a general discussion of the human causes of climate change and the effects on a global scale presently and in the future. For example, over the past 800,000 years, carbon dioxide levels have never been above 300 ppm, but they surpassed that threshold in 1911 and have reached 420 ppm today. The trapping of heat in Earth’s atmosphere caused by the increase in carbon dioxide and other greenhouse gases is leading to multiple phenomena that impact health, such as longer growing seasons; increased droughts, heat waves, and wildfire seasons; and higher temperatures. These changes, in turn, affect allergens and asthma.

Children are particularly vulnerable to climate change impacts because they have a higher risk for developing asthma, allergic disease, and infections, Matsui said. Childhood is a critical period for lung and immune development, and the Environmental Protection Agency’s 2023 Climate Change and Children’s Health and Well-Being report projects that an increase of 2° C in global warming will result in an additional 34,500 pediatric asthma cases and 228,000 allergic rhinitis cases per year, driven largely by predicted increases in ozone and 2.5-µm particulate matter. The report also forecasts an increase in 6240 asthma emergency department visits and 332 additional respiratory hospitalizations per year. 

“We know that these associations that we see between climate change exposures and poor respiratory health outcomes in kids are biologically plausible,” Matsui said. “They’re not just correlation without causation. A lot of the mechanisms for how air pollution, allergies, and other factors directly affect the lungs of the airway epithelium have been worked out.” 
 

An Increase in Allergens and Viral Infections

Pediatricians should prepare for anticipated growth in allergens and viral infections. The longer growing seasons mean that pollen seasons will also lengthen. Meanwhile, higher concentrations of carbon dioxide cause individual plants to produce more pollen. 

“As the winters get warmer, mice that might not be able to survive during the winter are surviving, and mice reproduce at a very rapid rate,” she said. “The increase in moisture means that dust mites, which absorb their water — they drink by absorbing humidity that’s in the air — will be present in higher concentrations, and their range will expand.”

Fungal and mold exposures are also increasing, not just outdoors but also indoors, “and there are all sorts of allergic and respiratory health consequences of fungal exposure,” Matsui said. As hurricanes and flooding increase, storm damage can also make indoor environments more conducive to fungal and mold growth. 

Extreme weather from climate change also affects infrastructure. “When there’s healthcare infrastructure disruption and other infrastructure disruption, it adds to the challenge,” she said. “It compounds all the other threat to health from climate change, so this overall problem of climate change and health is multidimensional and very complicated.”

Then there’s the impact of climate change on respiratory viruses, which are a major driver of asthma exacerbations, Matsui said. The greater variability in daytime temperatures affects environmental reservoirs, transmission patterns, geographical ranges, and seasonality of various respiratory pathogens. The prevalence of respiratory syncytial virus infections, for example, increases during humid periods. 

“This is coupled with the fact that the projected increases in air pollution increase susceptibility to respiratory virus infections,” Matsui said. “In fact, climate change and air pollution are inextricably linked.” 
 

Climate Change and Air Pollution

Climate disruption creates extreme weather patterns that then lead to worsening air quality due to high temperatures; heavier precipitation; and more forest fires, droughts, dust storms, thunderstorms, hurricanes, stagnation events, and other extreme weather. Matsui shared a map showing the substantial increase in days with stagnant air since 1973. During stagnation events, air pollution builds up in the atmosphere because of a stable air mass that remains over a region for several days, with low-level winds and no precipitation. 

The pollutants can then contribute to rising temperatures. Black carbon particulate matter released from the burning of forests and other biomass absorbs more solar radiation, further contributing to temperature increases. Data from the National Bureau of Economic Research has shown that the US made big strides in reducing air pollution from 2009 through 2016, but it began to reverse in 2016 as severe weather events picked up. 

Pediatricians need to be cognizant of the synergistic effect of these different impacts as well. “We oftentimes talk about these problems in a silo, so we may talk about air pollution and health effects, or allergens and health effects, or heat and health effects, but all of these interact with each other and further compound the health effects,” compared to just one of them in isolation, Matsui said.

For example, air pollution increases sensitivity to allergen exposure and increases reaction severity, which disrupts the immune tolerance to allergens. “Heat and air pollution also interact, and the combination of the two is more deadly than either one alone,” she said. 

Air pollution from wildfire smoke is also more toxic to the lungs than air pollution from other sources, so if there’s wildfire-based air pollution, the impact on respiratory hospitalizations is significantly greater. Even in places that would not otherwise be at risk for wildfires, the threat remains of air pollution from more distant fires, as New York City experienced from Canadian wildfires last year. 

“This is a problem that is not just isolated to the parts of the world where the wildfires are located,” Matsui said.

Moon, who practices in New York City, said he really appreciated Matsui’s perspectives and nuanced advice as a subspecialist “because it’s obvious that the way we deliver healthcare is going to have to change based on climate change.” He hopes to see more subspecialists from other pediatric areas getting involved in looking at climate impacts and providing nuanced advice about changing clinical care similar to the examples Matsui provided. 

Air pollution can also be deadly, as a landmark case in the United Kingdom revealed a few years ago when the court ruled that a child’s death from an asthma attack was directly due to air pollution. In addition to causing worse asthma symptoms and exacerbations, air pollution also adds to the risk of developing asthma and impedes lung growth, all of which disproportionately affects disadvantaged and minoritized communities, she said. 
 

Greater Impact on Disadvantaged Populations

Matsui called attention to the equity implications of climate change impacts on health. 

“If you have a community that does not have the infrastructure and access to resources, and that same community has a prevalence of asthma that is double that of their more advantaged and white counterparts, then the impacts of climate change are going to be amplified even more,” she said.

For example, a 2019 study found that the biggest predictor of the location of ragweed plants has to do with vacant lots and demolition of housing. Ragweed plants being more common in neighborhoods with vacant lots will disproportionately affect disadvantaged neighborhoods, she said. Another study found in Baltimore that mouse allergens — specifically urine — were a bigger cause of asthma in low-income children than were cockroach allergens. 

“It’s important to consider context,” including age, gender and social and behavioral context, she said. “We as pediatricians know that children are particularly vulnerable, and what happens to them has an effect across the lifespan.” 

Furthermore, pediatricians are aware that disadvantaged and minoritized communities lack infrastructure; often live in areas with greater air pollution; often have heat islands in their communities without protection, such as tree canopy; and may be at greater flooding risk. “Poverty is also associated with increased vulnerability” because of poorer housing and infrastructure, less education, less access to care, more preexisting health conditions and greater discrimination, she said.
 

Three Cornerstone Interventions

Interventions fall into three main buckets, Matsui said: mitigation, adaption, and resilience. 

“Mitigation means reducing greenhouse gas and air pollution production and trying to enhance sinks for greenhouse gases,” she said. Mitigation strategies primarily occur at the policy level, with improved regulation, treaties, and market-based approaches, such as carbon tax and cap and trade. 

Adaptation includes actions that lessen the impact on health and environment, such as infrastructure changes and implementation of air conditioning. Examples of climate change adaptation strategies also mostly come from policy but largely at state and local levels, where individual pediatricians have a greater voice and influence. These can include changes in urban planning to address heat islands, flooding risk, and public transportation’s contribution to air pollution and climate change. It can also include changes in housing regulation and policy and investments in healthcare, such as expanded Medicaid and health insurance and investing in disaster planning and readiness. 

“Resilience is a more holistic concept,” Matsui said, “which advocates for system-wide, multilevel changes and involves a range of strategies to enhance social, human, natural, physical, and financial capacities.”
 

What Pediatricians Can Do

Pediatricians have an important role to play when it comes to climate change and health impacts. 

“The first step is sort of understanding the complexity of climate change in terms of its potential health effects, but also being prepared to talk with our patients and their families about it,” Matsui said. “The second step is advocacy.” She drew attention to the February policy statement in Pediatrics that discusses precisely the ways in which pediatricians can leverage their expertise and credibility. 

“Pediatricians are ideal advocates with whom to partner and uplift youth and community voices working to advance zero-carbon energy policy and climate justice,” she said. “There are many opportunities to advocate for climate solution policies at the local, state, national, and even international level.” 

These roles can include educating elected officials and health insurance entities about the risks that climate change poses to allergies, asthma, and child health more broadly, as well as the benefits of local solutions, including improved air quality, tree canopy, and green space. “There are lots of opportunities to engage with the community, including speaking at public hearings, serving as an expert testimony, and writing letters to the editor,” she said. 

The impact of these efforts can be further maximized by working with other healthcare professionals. Lori Byron, MD, a pediatrician from Red Lodge, Montana, who heads the AAP Chapter Climate Advocates program, noted during Q&A that every AAP chapter in the country has climate advocates. She added that the AAP is the first medical board to have climate modules in their maintenance of certification specifically designed to incorporate climate change education into well visits.
 

Adjusting Clinical Care

Meanwhile, in patient care, Matsui acknowledged it can be frustrating to think about what a massive impact climate has and simultaneously challenging to engage families in discussions about it. However, a wide range of resources are available that can be provided to patients. 

“For a patient in front of you, being informed and prepared to talk about it is the first step to being able to assess their climate change risk and provide tailored guidance,” she said. Tailored guidance takes into account the child’s specific health situation and the risks they’re most likely to encounter, such as wildfire smoke, air pollution, longer pollen seasons, environmental allergens, or disruption of infrastructure. 

“If I am seeing a patient with asthma who is allergic to a particular pollen, I can anticipate that pollen may be present in higher levels of the future, and that the season for that pollen may be longer,” Matsui said. “So if I’m thinking about allergen immunotherapy for that patient, future risk may be something that would push the conversation and the shared decision-making” from possible consideration to more serious consideration, depending on the child’s age. 

“Another example is a patient with asthma, thinking about wildfire risk and having them prepared, because we know from data that wildfire air pollution is going to be worse for that child than pollution from other sources, and there are ways for them to be prepared,” Matsui said. For instance, having an HVAC system with a high-grade air filter (at least a MERV 13) will filter the air better if a wildfire causes smoke to descend over an area. Portable, less expensive HEPA filters are also an option if a family cannot upgrade their system, and wearing an N95 or N95-equivalent mask can also reduce the impact of high air pollution levels. 

An example of thinking about the impact of potential infrastructure disruption could be ensuring patients have enough of all their medications if they’re close to running out. “It’s important for them to always have think about their medications and get those refills ahead of a storm,” she said.
 

Additional Resources 

Understanding that pediatricians may not have time to discuss all these issues or have broader conversations about climate change during visits, Matsui highlighted the AAP website of resources on climate change. In addition to resources for pediatricians, such as a basic fact sheet about climate change impacts on children’s health and the technical report that informed the policy statement, the site has multiple resources for families:

• Climate Change Impact: Safeguarding Your Family’s Health and Well-being (video), How to Talk With Children About Climate Change, Climate Change & Children’s Health: AAP Policy Explained, Climate Checkup for Children’s Health: Little Changes With Big Impact, How Climate Change Can Make Children Sick: What Parents Need to Know, Climate Change & Wildfires: Why Kids Are Most at Risk, Climate Change, Extreme Weather & Children: What Families Need to Know, Extreme Heat & Air Pollution: Health Effects on Babies & Pregnant People, and

The following resources can also be helpful to pediatricians and/or families:

• Ready.gov, AirNow, Patient Exposure and the Air Quality Index, Protecting Vulnerable Patient Populations from Climate Hazards: A Referral Guide for Health Professionals from the US Department of Health and Human Services, Low Income Home Energy Assistance Program (LIHEAP), Weatherization Assistance Program, and the Disaster Supplemental Nutrition Assistance Program (D-SNAP)

In some states, Medicaid will provide or cover the cost of air conditioning and/or air filters.

The presentation did not involve external funding. Drs. Matsui and Moon had no disclosures.

ORLANDO — It’s important for pediatricians not only to understand the causes and effects of climate change but also to know how to discuss this issue with families and make risk-based adjustments to their clinical practice based on the individual health and circumstances of each patient. That’s one of the key messages delivered at the annual meeting of the American Academy of Pediatrics (AAP) by Elizabeth C. Matsui, MD, MHS, professor of population health and pediatrics and director of the Center for Health and Environment Education and Research at the University of Texas at Austin Dell Medical School. 

“Even though climate change has been here and has been affecting health already for a while, it’s just really impossible to ignore right now,” she told attendees in a session focused on climate change impacts on allergies and asthma. “The challenge is connecting the dots between something that is much larger, or feels much larger, than the patient and the family that’s in front of you.” 

The reality, however, is that climate change is now impacting patients’ health on an individual level, and pediatricians have a responsibility to understand how that’s happening and to help their families prepare for it. 

“From the perspective of someone who went into medicine to practice and take care of the individual patient, I think it has been more difficult to connect those dots, and for the people in this room, it’s our job to connect those dots,” Matsui said. She also acknowledged that many of the solutions are frustratingly limited to the policy level and challenging to implement, “but it doesn’t mean that we can’t make a difference for the patients who are in front of us.” 

Charles Moon, MD, a pediatrician and Pediatric Environmental Health Fellow at the Children’s Environmental Health Center, Icahn School of Medicine at Mount Sinai, New York City, found the talk particularly helpful in providing information about both the broader issue and what it means on a local practice level. 

“The biggest takeaway is that more people and more pediatricians are tuning in to this issue and realizing the dangers,” Moon said. “It’s clear that a larger community is forming around this, and I think we are at the cusp where more and more people will be coming in. We are really focusing on taking all the data and trying to figure out solutions. I think the solutions orientation is the most important part.” 
 

Understanding the Big Picture

Matsui opened with a general discussion of the human causes of climate change and the effects on a global scale presently and in the future. For example, over the past 800,000 years, carbon dioxide levels have never been above 300 ppm, but they surpassed that threshold in 1911 and have reached 420 ppm today. The trapping of heat in Earth’s atmosphere caused by the increase in carbon dioxide and other greenhouse gases is leading to multiple phenomena that impact health, such as longer growing seasons; increased droughts, heat waves, and wildfire seasons; and higher temperatures. These changes, in turn, affect allergens and asthma.

Children are particularly vulnerable to climate change impacts because they have a higher risk for developing asthma, allergic disease, and infections, Matsui said. Childhood is a critical period for lung and immune development, and the Environmental Protection Agency’s 2023 Climate Change and Children’s Health and Well-Being report projects that an increase of 2° C in global warming will result in an additional 34,500 pediatric asthma cases and 228,000 allergic rhinitis cases per year, driven largely by predicted increases in ozone and 2.5-µm particulate matter. The report also forecasts an increase in 6240 asthma emergency department visits and 332 additional respiratory hospitalizations per year. 

“We know that these associations that we see between climate change exposures and poor respiratory health outcomes in kids are biologically plausible,” Matsui said. “They’re not just correlation without causation. A lot of the mechanisms for how air pollution, allergies, and other factors directly affect the lungs of the airway epithelium have been worked out.” 
 

An Increase in Allergens and Viral Infections

Pediatricians should prepare for anticipated growth in allergens and viral infections. The longer growing seasons mean that pollen seasons will also lengthen. Meanwhile, higher concentrations of carbon dioxide cause individual plants to produce more pollen. 

“As the winters get warmer, mice that might not be able to survive during the winter are surviving, and mice reproduce at a very rapid rate,” she said. “The increase in moisture means that dust mites, which absorb their water — they drink by absorbing humidity that’s in the air — will be present in higher concentrations, and their range will expand.”

Fungal and mold exposures are also increasing, not just outdoors but also indoors, “and there are all sorts of allergic and respiratory health consequences of fungal exposure,” Matsui said. As hurricanes and flooding increase, storm damage can also make indoor environments more conducive to fungal and mold growth. 

Extreme weather from climate change also affects infrastructure. “When there’s healthcare infrastructure disruption and other infrastructure disruption, it adds to the challenge,” she said. “It compounds all the other threat to health from climate change, so this overall problem of climate change and health is multidimensional and very complicated.”

Then there’s the impact of climate change on respiratory viruses, which are a major driver of asthma exacerbations, Matsui said. The greater variability in daytime temperatures affects environmental reservoirs, transmission patterns, geographical ranges, and seasonality of various respiratory pathogens. The prevalence of respiratory syncytial virus infections, for example, increases during humid periods. 

“This is coupled with the fact that the projected increases in air pollution increase susceptibility to respiratory virus infections,” Matsui said. “In fact, climate change and air pollution are inextricably linked.” 
 

Climate Change and Air Pollution

Climate disruption creates extreme weather patterns that then lead to worsening air quality due to high temperatures; heavier precipitation; and more forest fires, droughts, dust storms, thunderstorms, hurricanes, stagnation events, and other extreme weather. Matsui shared a map showing the substantial increase in days with stagnant air since 1973. During stagnation events, air pollution builds up in the atmosphere because of a stable air mass that remains over a region for several days, with low-level winds and no precipitation. 

The pollutants can then contribute to rising temperatures. Black carbon particulate matter released from the burning of forests and other biomass absorbs more solar radiation, further contributing to temperature increases. Data from the National Bureau of Economic Research has shown that the US made big strides in reducing air pollution from 2009 through 2016, but it began to reverse in 2016 as severe weather events picked up. 

Pediatricians need to be cognizant of the synergistic effect of these different impacts as well. “We oftentimes talk about these problems in a silo, so we may talk about air pollution and health effects, or allergens and health effects, or heat and health effects, but all of these interact with each other and further compound the health effects,” compared to just one of them in isolation, Matsui said.

For example, air pollution increases sensitivity to allergen exposure and increases reaction severity, which disrupts the immune tolerance to allergens. “Heat and air pollution also interact, and the combination of the two is more deadly than either one alone,” she said. 

Air pollution from wildfire smoke is also more toxic to the lungs than air pollution from other sources, so if there’s wildfire-based air pollution, the impact on respiratory hospitalizations is significantly greater. Even in places that would not otherwise be at risk for wildfires, the threat remains of air pollution from more distant fires, as New York City experienced from Canadian wildfires last year. 

“This is a problem that is not just isolated to the parts of the world where the wildfires are located,” Matsui said.

Moon, who practices in New York City, said he really appreciated Matsui’s perspectives and nuanced advice as a subspecialist “because it’s obvious that the way we deliver healthcare is going to have to change based on climate change.” He hopes to see more subspecialists from other pediatric areas getting involved in looking at climate impacts and providing nuanced advice about changing clinical care similar to the examples Matsui provided. 

Air pollution can also be deadly, as a landmark case in the United Kingdom revealed a few years ago when the court ruled that a child’s death from an asthma attack was directly due to air pollution. In addition to causing worse asthma symptoms and exacerbations, air pollution also adds to the risk of developing asthma and impedes lung growth, all of which disproportionately affects disadvantaged and minoritized communities, she said. 
 

Greater Impact on Disadvantaged Populations

Matsui called attention to the equity implications of climate change impacts on health. 

“If you have a community that does not have the infrastructure and access to resources, and that same community has a prevalence of asthma that is double that of their more advantaged and white counterparts, then the impacts of climate change are going to be amplified even more,” she said.

For example, a 2019 study found that the biggest predictor of the location of ragweed plants has to do with vacant lots and demolition of housing. Ragweed plants being more common in neighborhoods with vacant lots will disproportionately affect disadvantaged neighborhoods, she said. Another study found in Baltimore that mouse allergens — specifically urine — were a bigger cause of asthma in low-income children than were cockroach allergens. 

“It’s important to consider context,” including age, gender and social and behavioral context, she said. “We as pediatricians know that children are particularly vulnerable, and what happens to them has an effect across the lifespan.” 

Furthermore, pediatricians are aware that disadvantaged and minoritized communities lack infrastructure; often live in areas with greater air pollution; often have heat islands in their communities without protection, such as tree canopy; and may be at greater flooding risk. “Poverty is also associated with increased vulnerability” because of poorer housing and infrastructure, less education, less access to care, more preexisting health conditions and greater discrimination, she said.
 

Three Cornerstone Interventions

Interventions fall into three main buckets, Matsui said: mitigation, adaption, and resilience. 

“Mitigation means reducing greenhouse gas and air pollution production and trying to enhance sinks for greenhouse gases,” she said. Mitigation strategies primarily occur at the policy level, with improved regulation, treaties, and market-based approaches, such as carbon tax and cap and trade. 

Adaptation includes actions that lessen the impact on health and environment, such as infrastructure changes and implementation of air conditioning. Examples of climate change adaptation strategies also mostly come from policy but largely at state and local levels, where individual pediatricians have a greater voice and influence. These can include changes in urban planning to address heat islands, flooding risk, and public transportation’s contribution to air pollution and climate change. It can also include changes in housing regulation and policy and investments in healthcare, such as expanded Medicaid and health insurance and investing in disaster planning and readiness. 

“Resilience is a more holistic concept,” Matsui said, “which advocates for system-wide, multilevel changes and involves a range of strategies to enhance social, human, natural, physical, and financial capacities.”
 

What Pediatricians Can Do

Pediatricians have an important role to play when it comes to climate change and health impacts. 

“The first step is sort of understanding the complexity of climate change in terms of its potential health effects, but also being prepared to talk with our patients and their families about it,” Matsui said. “The second step is advocacy.” She drew attention to the February policy statement in Pediatrics that discusses precisely the ways in which pediatricians can leverage their expertise and credibility. 

“Pediatricians are ideal advocates with whom to partner and uplift youth and community voices working to advance zero-carbon energy policy and climate justice,” she said. “There are many opportunities to advocate for climate solution policies at the local, state, national, and even international level.” 

These roles can include educating elected officials and health insurance entities about the risks that climate change poses to allergies, asthma, and child health more broadly, as well as the benefits of local solutions, including improved air quality, tree canopy, and green space. “There are lots of opportunities to engage with the community, including speaking at public hearings, serving as an expert testimony, and writing letters to the editor,” she said. 

The impact of these efforts can be further maximized by working with other healthcare professionals. Lori Byron, MD, a pediatrician from Red Lodge, Montana, who heads the AAP Chapter Climate Advocates program, noted during Q&A that every AAP chapter in the country has climate advocates. She added that the AAP is the first medical board to have climate modules in their maintenance of certification specifically designed to incorporate climate change education into well visits.
 

Adjusting Clinical Care

Meanwhile, in patient care, Matsui acknowledged it can be frustrating to think about what a massive impact climate has and simultaneously challenging to engage families in discussions about it. However, a wide range of resources are available that can be provided to patients. 

“For a patient in front of you, being informed and prepared to talk about it is the first step to being able to assess their climate change risk and provide tailored guidance,” she said. Tailored guidance takes into account the child’s specific health situation and the risks they’re most likely to encounter, such as wildfire smoke, air pollution, longer pollen seasons, environmental allergens, or disruption of infrastructure. 

“If I am seeing a patient with asthma who is allergic to a particular pollen, I can anticipate that pollen may be present in higher levels of the future, and that the season for that pollen may be longer,” Matsui said. “So if I’m thinking about allergen immunotherapy for that patient, future risk may be something that would push the conversation and the shared decision-making” from possible consideration to more serious consideration, depending on the child’s age. 

“Another example is a patient with asthma, thinking about wildfire risk and having them prepared, because we know from data that wildfire air pollution is going to be worse for that child than pollution from other sources, and there are ways for them to be prepared,” Matsui said. For instance, having an HVAC system with a high-grade air filter (at least a MERV 13) will filter the air better if a wildfire causes smoke to descend over an area. Portable, less expensive HEPA filters are also an option if a family cannot upgrade their system, and wearing an N95 or N95-equivalent mask can also reduce the impact of high air pollution levels. 

An example of thinking about the impact of potential infrastructure disruption could be ensuring patients have enough of all their medications if they’re close to running out. “It’s important for them to always have think about their medications and get those refills ahead of a storm,” she said.

Higher concentrations of specific volatile organic compounds (VOCs) in daycare centers were significantly associated with an increased risk for wheezing in children who attended these centers, based on data from more than 500 children.

“There is an increasing concern about of the role of Indoor Air Quality (IAQ) in development of respiratory disorders like asthma, especially in children whose immune system is under development, and they are more vulnerable to the effects of poor air quality,” lead author Ioannis Sakellaris, PhD, of Université Paris-Saclay, Villejuif, France, said in an interview. However, the effects of specific pollutants on the health of young children in daycare settings has not been examined, he said. 

In a presentation at the European Respiratory Society Congress, Sakellaris reviewed data from the French CRESPI cohort study, an epidemiological study of the impact of exposures to disinfectants and cleaning products on workers and children in daycare centers in France.

The study population included 532 children (47.4% girls) with a mean age of 22.3 months (aged 3 months to 4 years) in 106 daycare centers. A total of 171 children reportedly experienced at least one episode of wheezing since birth. 

A total of 67 VOCs were measured during one day, and concentrations were studied in four categories based on quartiles. The researchers evaluated three child wheezing outcomes based on parental questionnaires: Ever wheeze since birth, recurrent wheeze (≥ 3 times since birth), and ever wheeze with inhaled corticosteroid use. The researchers adjusted for factors including child age and parental smoking status and education level.

Overall, ever wheezing was significantly associated with higher concentrations of 1,2,4-trimethylbenzene (odds ratio [OR] for Q4 vs Q1, 1.56; P = .08 for trend), 1-methoxy-2-propylacetate (OR, 1.62; P = .01), decamethylcyclopentasiloxane (OR, 2.12; P = .004), and methylisobutylcetone (OR, 1.85; P < .001).

The results emphasize the significant role of IAQ in respiratory health, said Sakellaris. “Further efforts to reduce pollutant concentrations and limit sources are needed,” he said. In addition, more studies on the combined effect of multiple VOCs are necessary for a deeper understanding of the complex relations between IAQ and children’s respiratory health, he said.
 

Pay Attention to Indoor Pollutants

“Since the COVID-19 pandemic, the use of cleaning products and disinfectants has exploded,” Alexander S. Rabin, MD, of the University of Michigan, Ann Arbor, Michigan, said in an interview. Although many of these cleaning agents contain chemicals, including VOCs, that are known respiratory irritants, little is known about the relationship between VOCs and children’s respiratory outcomes in daycare settings, said Rabin, who was not involved in the study.

“I was struck by the wide array of VOCs detected in daycare settings,” Rabin said. However, the relationship to childhood wheeze was not entirely surprising as the VOCs included the known irritants benzene and toluene, he added.

The results suggest that exposure to VOCs, not only in cleaning agents but also building materials and other consumer products in daycare settings, may be associated with an increased risk for wheeze in children, said Rabin. 

However, “it is important to know more about confounding variables, including concurrent rates of respiratory infection that are common among children,” said Rabin. “As the authors highlight, further work on the compound effects of multiple pollutants would be of interest. Lastly, it would be helpful to clearly identify the most common sources of VOCs that place children at greatest risk for wheeze, so that appropriate steps can be taken to mitigate risk,” he said.

The original CRESPI cohort study was supported by ANSES, ADEME, Fondation de France, and ARS Ile-de-France. Sakellaris and Rabin had no financial conflicts to disclose.

ORLANDO — More than half of youth improved after receiving a dose of naloxone by emergency medical services (EMS) after an emergency dispatch call, according to research presented at the American Academy of Pediatrics 2024 National Conference.

“Emergency responders or EMS are often the first to arrive to an opioid poisoning, and they’re often the first to give naloxone, a potentially lifesaving medication,” said Christopher E. Gaw, MD, MPH, MBE, assistant professor of pediatrics at The Ohio State University College of Medicine and an emergency medicine physician at Nationwide Children’s Hospital in Columbus, Ohio.

Ohio State University

“Our study highlights and underscores its safety of use in the prehospital setting, and this is also supported by other data,” Gaw said. “Efforts to support public distribution and education on naloxone can really help each and every one of us as individual citizens prevent pediatric harm from the opioid crisis.”

Additional research at the meeting showed that teens’ knowledge, attitudes, and confidence about recognizing overdoses and assisting with naloxone administration improved following a peer-to-peer training program, suggesting that teens can play an important role in reducing youth mortality from overdoses.

An average of 22 American teens died from overdose every week in 2022, and as counterfeit pill use has increased among youth, research has found that fentanyl was detected in 93% of overdose deaths with counterfeit pills, according to Talia Puzantian, PharmD, BCPP, of the Keck Graduate Institute School of Pharmacy, Claremont, California, who led the study on peer education. Yet a recent survey had found that less than a third of teens (30%) knew what naloxone was, and only 14% knew how to administer it.

“Ensuring that adolescents have easy and confidential access to naloxone is important and can save lives,” said Taylor Nichols, MD, assistant clinical professor at the University of California San Francisco and an emergency medicine and addiction medicine–certified physician. “I have had teen patients who have told me that they have had to use naloxone obtained from our clinic on friends when they have accidentally overdosed.”

EMS Naloxone Administration to Youth

EMS clinicians are often the first healthcare providers to respond to an opioid overdose or poisoning event, and evidence-based guidelines for EMS naloxone administration were developed in 2019 to support this intervention. Gaw’s team investigated the frequency and demographics of pediatric administration of naloxone.

They analyzed data from the National Emergency Medical Services Information System on EMS activations for administration of at least one dose of naloxone during 2022 to those aged 0-17. There were 6215 EMS pediatric administrations of naloxone that year, and in the vast majority of cases (82%), the patient had not received a naloxone injection prior to EMS’s arrival.

Most patients (79%) were aged 13-17 years, but 10% were in the 6-12 age group. The remaining patients included 6% infants younger than 1 year and 4% aged 6-12 years. Just over half were for males (55%), and most were dispatched to a home or residential setting (61%). One in five incidents (22%) occurred at a non-healthcare business, 9% on a street or highway, and the rest at a healthcare facility or another location.

Most of the incidents occurred in urban areas (86%), followed by rural (7%), suburban (6%), and wilderness (1.4%). More occurred in the US South (42%) than in the West (29%), Midwest (22%), or Northeast (7.5%).

A key takeaway of those demographic findings is that ingestions and accidental poisonings with opioids can occur in children of any age, Nichols said. “Every single home that has any opioids in the home should absolutely have naloxone immediately available as well,” he said. “Every single person who is prescribed opioids should also have naloxone available and accessible and to be sure that the naloxone is not expired or otherwise tampered with and update that every few years.” He noted that Narcan expiration was recently extended from 3 years to 4 years by the US Food and Drug Administration (FDA).

“I always advise that people who have opioid medications keep them stored safely and securely,” Nichols said. “However, I also acknowledge that even perfect systems fail and that people make mistakes and may accidentally leave medication out, within reach, or otherwise unsecured. If that happens, and someone were to intentionally or unintentionally get into that medication and potentially overdose as a result, we want to have that reversal medication immediately available to reverse the overdose.”

In nearly all cases (91%), EMS provided advanced life support, with only 7.5% patients receiving basic life support and 1.5% receiving specialty critical care. Just under a third (29%) of the dispatch calls were for “overdose/poisoning/ingestion.” Other dispatch calls included “unconscious/fainting/near-fainting” (21%) or “cardiac arrest/death” (17%), but the frequency of each dispatch label varied by age groups.

For example, 38% of calls for infants were for cardiac arrest, compared with 15% of calls for older teens and 18% of calls for 6-12 year olds. An overdose/poisoning dispatch was meanwhile more common for teens (32%) than for infants (13%), younger children (23%), and older children/tweens (18%). Other dispatch complaints included “sick person/person down/unknown problem” (12%) and “breathing problem” (5%).

A possible reason for these variations is that “an overdose might be mistaken for another medical emergency, or vice versa, because opioid poisonings can be challenging to recognize, especially in young children and in the pediatric population,” Gaw said. “Both the public and emergency responders should maintain a high level of suspicion” of possible overdose for children with the signs or symptoms of it, such as low breathing, unresponsiveness, or small pupils.

In most cases (87%), the patient was not in cardiac arrest, though the patient had entered cardiac arrest before EMS’s arrival in 11.5% of cases. Two thirds of cases only involved one dose of naloxone, while the other 33% involved two doses.

Ryan Marino, MD, an addiction medicine specialist and an associate professor of emergency medicine at Case Western Reserve University School of Medicine in Cleveland, Ohio, who was not involved in the study, took note of the high proportion of cases in which two doses were administered.

“While there is, in my professional opinion, almost no downside to giving naloxone in situations like this, and everybody should have it available and know how to use it, I would caution people on the risk of anchor bias, especially when more than two doses of naloxone are given, since we know that one should be an effective amount for any known opioid overdose,” Marino said. Anchoring bias refers to the tendency for individuals to rely more heavily on the first piece of information they receive about a topic or situation.

“For first responders and healthcare professionals, the importance of additional resuscitation measures like oxygenation and ventilation are just as crucial,” Marino said. “People should not be discouraged if someone doesn’t immediately respond to naloxone as overdose physiology can cause mental status to stay impaired for other reasons beyond direct drug effect, such as hypercarbia, but continue to seek and/or provide additional emergency care in these situations.”

Patients improved after one dose in just over half the cases (54%), and their conditions were unchanged in 46% of cases. There were only 11 cases in which the patient’s condition worsened after a naloxone dose (0.2%). Most of the cases (88%) were transported by EMS, and there were 13 total deaths at the scene (0.2%).

Nichols found the low incidence of worsening clinical status particularly striking. “This is further evidence of a critically important point — naloxone is purely an opioid antagonist, and only binds to opioid receptors, such that if a person has not overdosed on opioids or does not otherwise have opioids in their system, naloxone will not have a significant effect and will not cause them harm,” Nichols said.

“The most common causes of harm are due to rapid reversal of overdose and the potential risks involved in the rapid reversal of opioid effects and potentially precipitating withdrawal, and as this paper demonstrates, these are exceedingly rare,” he said. “Given that, we should have an incredibly low barrier to administer naloxone appropriately.”

The study was limited by inability to know how many true pediatric opioid poisonings are managed by EMS, so future research could look at linking EMS and emergency room hospital databases.
 

Improved Self-Efficacy in Teens

Another study showed that a peer-to-peer training program increased teens’ knowledge about overdoses from 34% before training to 79% after (P < .0001), and it substantially improved their confidence in recognizing an overdose and administering naloxone.

Nichols said the study shows the importance of ensuring “that adolescents know how to keep themselves and their friends safe in the case that they or anyone they know does end up using illicit substances which either intentionally or unintentionally contain opioids.”

This study assessed a training program with 206 students in a Los Angeles County high school who were trained by their peers between November 2023 and March 2024. The training included trends in teen overdose deaths, defining what opioids and fentanyl are, recognizing an overdose, and responding to one with naloxone.

The teens were an average 16 years old, about evenly split between boys and girls, and mostly in 11th (40%) or 12th (28%) grade, though nearly a third (29%) were 9th graders.

The students’ knowledge about fentanyl’s presence in counterfeit pills increased from 21% before the training to 68% afterward, and their correct identification of an overdose increased from 47% of participants to 90%.

The students’ confidence and attitudes toward helping with an overdose also improved substantially after the training. About two thirds agreed that non-medical people should be able to carry naloxone before the training, and that rose to 88% agreeing after the training. The proportion who agreed they would be willing to assist in an overdose rose from 77% before to 89% after training.

More dramatically, the teens’ confidence after training more than doubled in recognizing an overdose (from 31% to 81%) and more than tripled in their ability to give naloxone during an overdose (from 26% to 83%).

“The critical piece to keep in mind is that the concern about opioid overdose is respiratory depression leading to a lack of oxygen getting to the brain,” Nichols explained. “In the event of an overdose, time is brain — the longer the brain is deprived of oxygen, the lower the chance of survival. There is no specific time at which naloxone would become less effective at reversing an overdose.”

Therefore, people do not need to know the exact time that someone may have overdosed or how long they have been passed out in order to administer naloxone, he said. “The sooner naloxone is administered to someone who is unresponsive and who may have overdosed on opioids, the higher the likelihood of a successful reversal of an overdose and of saving a life.”

The peer-to-peer program was sponsored by the CARLOW Center for Medical Innovation, and the EMS study used no external funding. The authors of both studies and Marino had no disclosures. Nichols has consulted or clinically advised TV shows and health tech startup companies and has no disclosures related to naloxone or the pharmaceutical industry.

ORLANDO — More than half of youth improved after receiving a dose of naloxone by emergency medical services (EMS) after an emergency dispatch call, according to research presented at the American Academy of Pediatrics 2024 National Conference.

“Emergency responders or EMS are often the first to arrive to an opioid poisoning, and they’re often the first to give naloxone, a potentially lifesaving medication,” said Christopher E. Gaw, MD, MPH, MBE, assistant professor of pediatrics at The Ohio State University College of Medicine and an emergency medicine physician at Nationwide Children’s Hospital in Columbus, Ohio.

“Our study highlights and underscores its safety of use in the prehospital setting, and this is also supported by other data,” Gaw said. “Efforts to support public distribution and education on naloxone can really help each and every one of us as individual citizens prevent pediatric harm from the opioid crisis.”

Additional research at the meeting showed that teens’ knowledge, attitudes, and confidence about recognizing overdoses and assisting with naloxone administration improved following a peer-to-peer training program, suggesting that teens can play an important role in reducing youth mortality from overdoses.

An average of 22 American teens died from overdose every week in 2022, and as counterfeit pill use has increased among youth, research has found that fentanyl was detected in 93% of overdose deaths with counterfeit pills, according to Talia Puzantian, PharmD, BCPP, of the Keck Graduate Institute School of Pharmacy, Claremont, California, who led the study on peer education. Yet a recent survey had found that less than a third of teens (30%) knew what naloxone was, and only 14% knew how to administer it.

“Ensuring that adolescents have easy and confidential access to naloxone is important and can save lives,” said Taylor Nichols, MD, assistant clinical professor at the University of California San Francisco and an emergency medicine and addiction medicine–certified physician. “I have had teen patients who have told me that they have had to use naloxone obtained from our clinic on friends when they have accidentally overdosed.”

EMS Naloxone Administration to Youth

EMS clinicians are often the first healthcare providers to respond to an opioid overdose or poisoning event, and evidence-based guidelines for EMS naloxone administration were developed in 2019 to support this intervention. Gaw’s team investigated the frequency and demographics of pediatric administration of naloxone.

They analyzed data from the National Emergency Medical Services Information System on EMS activations for administration of at least one dose of naloxone during 2022 to those aged 0-17. There were 6215 EMS pediatric administrations of naloxone that year, and in the vast majority of cases (82%), the patient had not received a naloxone injection prior to EMS’s arrival.

Most patients (79%) were aged 13-17 years, but 10% were in the 6-12 age group. The remaining patients included 6% infants younger than 1 year and 4% aged 6-12 years. Just over half were for males (55%), and most were dispatched to a home or residential setting (61%). One in five incidents (22%) occurred at a non-healthcare business, 9% on a street or highway, and the rest at a healthcare facility or another location.

Most of the incidents occurred in urban areas (86%), followed by rural (7%), suburban (6%), and wilderness (1.4%). More occurred in the US South (42%) than in the West (29%), Midwest (22%), or Northeast (7.5%).

A key takeaway of those demographic findings is that ingestions and accidental poisonings with opioids can occur in children of any age, Nichols said. “Every single home that has any opioids in the home should absolutely have naloxone immediately available as well,” he said. “Every single person who is prescribed opioids should also have naloxone available and accessible and to be sure that the naloxone is not expired or otherwise tampered with and update that every few years.” He noted that Narcan expiration was recently extended from 3 years to 4 years by the US Food and Drug Administration (FDA).

“I always advise that people who have opioid medications keep them stored safely and securely,” Nichols said. “However, I also acknowledge that even perfect systems fail and that people make mistakes and may accidentally leave medication out, within reach, or otherwise unsecured. If that happens, and someone were to intentionally or unintentionally get into that medication and potentially overdose as a result, we want to have that reversal medication immediately available to reverse the overdose.”

In nearly all cases (91%), EMS provided advanced life support, with only 7.5% patients receiving basic life support and 1.5% receiving specialty critical care. Just under a third (29%) of the dispatch calls were for “overdose/poisoning/ingestion.” Other dispatch calls included “unconscious/fainting/near-fainting” (21%) or “cardiac arrest/death” (17%), but the frequency of each dispatch label varied by age groups.

For example, 38% of calls for infants were for cardiac arrest, compared with 15% of calls for older teens and 18% of calls for 6-12 year olds. An overdose/poisoning dispatch was meanwhile more common for teens (32%) than for infants (13%), younger children (23%), and older children/tweens (18%). Other dispatch complaints included “sick person/person down/unknown problem” (12%) and “breathing problem” (5%).

A possible reason for these variations is that “an overdose might be mistaken for another medical emergency, or vice versa, because opioid poisonings can be challenging to recognize, especially in young children and in the pediatric population,” Gaw said. “Both the public and emergency responders should maintain a high level of suspicion” of possible overdose for children with the signs or symptoms of it, such as low breathing, unresponsiveness, or small pupils.

In most cases (87%), the patient was not in cardiac arrest, though the patient had entered cardiac arrest before EMS’s arrival in 11.5% of cases. Two thirds of cases only involved one dose of naloxone, while the other 33% involved two doses.

Primary care screening for celiac disease (CD) in kids could improve health outcomes, and it appears cost effective over time, according to a Dutch analysis.

If these screening strategies are deemed feasible by clinicians and patients, then implementation in routine care is needed, lead author Jan Heijdra Suasnabar, MSc, of Leiden University Medical Centre in the Netherlands, and colleagues reported.

“Cohort studies have shown that CD likely develops early in life and can be easily diagnosed by detection of CD-specific antibodies against the enzyme tissue transglutaminase type 2 (IgA-TG2),” the investigators wrote in Gastroenterology.

Despite the ease of diagnosis, as few as one in five cases of CD are detected using current clinical strategies, meaning many cases are diagnosed years after symptom onset.

“Such high rates of missed/delayed diagnoses have been attributed to CD’s varied and nonspecific symptoms, lack of awareness, and the resource-intensive process necessary to establish the diagnosis,” Heijdra Suasnabar and colleagues wrote. “From an economic perspective, the burden of CD translates into substantial excess healthcare and societal costs.”

These practice gaps prompted the present study, which explored the long-term cost effectiveness of mass CD screening and active case finding among pediatric patients.

The investigators employed a model-based cost-effectiveness analysis with a hypothetical cohort representing all children with CD in the Netherlands. Iterations of this model evaluated long-term costs as these children moved through the healthcare system along various CD detection strategies.

The first strategy was based on the current Dutch approach, which is the same as that in the United States: Patients are only evaluated for CD if they present with symptoms that prompt suspicion of disease. Based on data from population-based studies, the model assumed that approximately one in three cases would be detected using this strategy.

The second strategy involved mass screening using IgA-TG2 point-of-care testing (sensitivity, 0.94; specificity, 0.944) via youth health care clinics, regardless of symptoms.

The third strategy, called “active case finding,” represented something of an intermediate approach, in which children with at least 1 CD-related symptom underwent point-of-care antibody testing.

For both mass screening and active case finding strategies, a positive antibody test was followed with confirmatory diagnostic testing.

Compared with current clinical approach, mass screening added 7.46 more quality-adjusted life-years (QALYs) per CD patient with an increased cost of €28,635 per CD patient. Active case finding gained 4.33 QALYs per CD patient while incurring an additional cost of €15,585 per CD patient.

Based on a willingness-to-pay threshold of €20,000 per QALY, the investigators deemed both strategies “highly cost effective,” compared with current standard of care. Some of these costs were offset by “substantial” reductions in productivity losses, they noted, including CD-related absences from work and school.

“Our results illustrate how an earlier detection of CD through screening or case finding, although more costly, leads to improved health outcomes and a reduction in disease burden, compared with current care,” Heijdra Suasnabar and colleagues wrote.

Their concluding remarks highlighted the conservative scenarios built into their model, and suggested that their findings offer solid evidence for implementing new CD-testing strategies.

“If found to be feasible and acceptable by clinicians and patients, these strategies should be implemented in the Netherlands,” they wrote.This study was supported by the Netherlands Organization for Health Research and Development. The investigators disclosed no conflicts of interest.

These practice gaps prompted the present study, which explored the long-term cost effectiveness of mass CD screening and active case finding among pediatric patients.

The investigators employed a model-based cost-effectiveness analysis with a hypothetical cohort representing all children with CD in the Netherlands. Iterations of this model evaluated long-term costs as these children moved through the healthcare system along various CD detection strategies.

The first strategy was based on the current Dutch approach, which is the same as that in the United States: Patients are only evaluated for CD if they present with symptoms that prompt suspicion of disease. Based on data from population-based studies, the model assumed that approximately one in three cases would be detected using this strategy.

The second strategy involved mass screening using IgA-TG2 point-of-care testing (sensitivity, 0.94; specificity, 0.944) via youth health care clinics, regardless of symptoms.

The third strategy, called “active case finding,” represented something of an intermediate approach, in which children with at least 1 CD-related symptom underwent point-of-care antibody testing.

For both mass screening and active case finding strategies, a positive antibody test was followed with confirmatory diagnostic testing.

Compared with current clinical approach, mass screening added 7.46 more quality-adjusted life-years (QALYs) per CD patient with an increased cost of €28,635 per CD patient. Active case finding gained 4.33 QALYs per CD patient while incurring an additional cost of €15,585 per CD patient.

Based on a willingness-to-pay threshold of €20,000 per QALY, the investigators deemed both strategies “highly cost effective,” compared with current standard of care. Some of these costs were offset by “substantial” reductions in productivity losses, they noted, including CD-related absences from work and school.

“Our results illustrate how an earlier detection of CD through screening or case finding, although more costly, leads to improved health outcomes and a reduction in disease burden, compared with current care,” Heijdra Suasnabar and colleagues wrote.

Their concluding remarks highlighted the conservative scenarios built into their model, and suggested that their findings offer solid evidence for implementing new CD-testing strategies.

“If found to be feasible and acceptable by clinicians and patients, these strategies should be implemented in the Netherlands,” they wrote.This study was supported by the Netherlands Organization for Health Research and Development. The investigators disclosed no conflicts of interest.

A strategy developed by Canadian researchers for encouraging older patients with insomnia to wean themselves from sleeping pills and improve their sleep through behavioral techniques is effective, data suggest. If proven helpful for the millions of older Canadians who currently rely on nightly benzodiazepines (BZDs) and non-BZDs (colloquially known as Z drugs) for their sleep, it might yield an additional benefit: Reducing resource utilization.

“We know that cognitive behavioral therapy for insomnia (CBTI) works. It’s recommended as first-line therapy because it works,” study author David Gardner, PharmD, professor of psychiatry at Dalhousie University in Halifax, Nova Scotia, Canada, told this news organization.

“We’re sharing information about sleeping pills, information that has been embedded with behavior-change techniques that lead people to second-guess or rethink their long-term use of sedative hypnotics and then bring that information to their provider or pharmacist to discuss it,” he said.

The results were published in JAMA Psychiatry.
 

Better Sleep, Fewer Pills

Dr. Gardner and his team created a direct-to-patient, patient-directed, multicomponent knowledge mobilization intervention called Sleepwell. It incorporates best practice– and guideline-based evidence and multiple behavioral change techniques with content and graphics. Dr. Gardner emphasized that it represents a directional shift in care that alleviates providers’ burden without removing it entirely.

To test the intervention’s effectiveness, Dr. Gardner and his team chose New Brunswick as a location for a 6-month, three-arm, open-label, randomized controlled trial; the province has one of the highest rates of sedative use and an older adult population that is vulnerable to the serious side effects of these drugs (eg, cognitive impairment, falls, and frailty). The study was called Your Answers When Needing Sleep in New Brunswick (YAWNS NB).

Eligible participants were aged ≥ 65 years, lived in the community, and had taken benzodiazepine receptor agonists (BZRAs) for ≥ 3 nights per week for 3 or more months. Participants were randomly assigned to a control group or one of the two intervention groups. The YAWNS-1 intervention group (n = 195) received a mailed package containing a cover letter, a booklet outlining how to stop sleeping pills, a booklet on how to “get your sleep back,” and a companion website. The YAWNS-2 group (n = 193) received updated versions of the booklets used in a prior trial. The control group (n = 192) was assigned treatment as usual (TAU).

A greater proportion of YAWNS-1 participants discontinued BZRAs at 6 months (26.2%) and had dose reductions (20.4%), compared with YAWNS-2 participants (20.3% and 14.4%, respectively) and TAU participants (7.5% and 12.8%, respectively). The corresponding numbers needed to mail to achieve an additional discontinuation was 5.3 YAWNS-1 packages and 7.8 YAWNS-2 packages.

At 6 months, BZRA cessation was sustained a mean 13.6 weeks for YAWNS-1, 14.3 weeks for YAWNS-2, and 16.9 weeks for TAU.

Sleep measures also improved with YAWNS-1, compared with YAWNs-2 and TAU. Sleep onset latency was reduced by 26.1 minutes among YAWNS-1 participants, compared with YAWNS-2 (P < .001), and by 27.7 minutes, compared with TAU (P < .001). Wake after sleep onset increased by 4.1 minutes in YAWNS-1, 11.1 minutes in YAWNS-2, and 7.5 minutes in TAU.

Although all participants underwent rigorous assessment before inclusion, less than half of participants receiving either intervention (36% in YAWNS-1 and 43% in YAWNS-2) contacted their provider or pharmacist to discuss BZD dose reductions. This finding may have resulted partly from limited access because of the COVID-19 pandemic, according to the authors.
 

A Stepped-Care Model

The intervention is intended to help patients “change their approach from sleeping pills to a short-term CBTI course for long-term sleep benefits, and then speak to their provider,” said Dr. Gardner.

He pointed to a post-study follow-up of the study participants’ health providers, most of whom had moderate to extensive experience deprescribing BZRAs, which showed that 87.5%-100% fully or nearly fully agreed with or supported using the Sleepwell strategy and its content with older patients who rely on sedatives.

“Providers said that deprescribing is difficult, time-consuming, and often not a productive use of their time,” said Dr. Gardner. “I see insomnia as a health issue well set up for a stepped-care model. Self-help approaches are at the very bottom of that model and can help shift the initial burden to patients and out of the healthcare system.”

Poor uptake has prevented CBTI from demonstrating its potential, which is a challenge that Charles M. Morin, PhD, professor of psychology at Laval University in Quebec City, Quebec, Canada, attributes to two factors. “Clearly, there aren’t enough providers with this kind of expertise, and it’s not always covered by public health insurance, so people have to pay out of pocket to treat their insomnia,” he said.

“Overall, I think that this was a very nice study, well conducted, with an impressive sample size,” said Dr. Morin, who was not involved in the study. “The results are quite encouraging, telling us that even when older adults have used sleep medications for an average of 10 years, it’s still possible to reduce the medication. But this doesn’t happen alone. People need to be guided in doing that, not only to decrease medication use, but they also need an alternative,” he said.

Dr. Morin questioned how many patients agree to start with a low intensity. “Ideally, it should be a shared decision paradigm, where the physician or whoever sees the patient first presents the available options and explains the pluses and minuses of each. Some patients might choose medication because it’s a quick fix,” he said. “But some might want to do CBTI, even if it takes more work. The results are sustainable over time,” he added.

The study was jointly funded by the Public Health Agency of Canada and the government of New Brunswick as a Healthy Seniors Pilot Project. Dr. Gardner and Dr. Morin reported no relevant financial relationships.
