CGM With Geriatric Care Simplifies T1D Management in Seniors
TOPLINE:
METHODOLOGY:
- Researchers evaluated the effectiveness of CGM use enhanced by geriatric principles in adults aged ≥ 65 years with T1D and at least two episodes of hypoglycemia (blood glucose level, < 70 mg/dL for ≥ 20 minutes over 2 weeks), who were either CGM-naive or CGM users prior to the study.
- Participants were randomly assigned to an intervention group using CGM with geriatric principles (ie, adjusting goals based on overall health and simplifying regimens based on CGM patterns and clinical characteristics) or a control group receiving usual care by their endocrinologist.
- The primary outcome was the change in duration of hypoglycemia from baseline to 6 months.
- A cost-effectiveness analysis was also performed for the intervention using a healthcare sector perspective, considering the cost of CGM devices and the cost of medical staff time.
TAKEAWAY:
- Researchers included 131 participants (mean age, 71 years), of whom 68 were in the intervention group (35 CGM-naive) and 63 in the control group (23 CGM-naive).
- The intervention group showed a median reduction of 2.6% in the duration of hypoglycemia vs a 0.3% reduction in the control group (median difference, −2.3%; P < .001).
- This reduction was observed in both CGM users (median difference, −1.2%) and CGM-naive participants (median difference, −2.8%) in the intervention group.
- No significant difference in A1c levels was observed between the intervention and control groups, indicating that CGM enhanced with geriatric principles did not worsen glycemic control.
- The intervention was associated with an incremental cost-effectiveness ratio of $71,623 per quality-adjusted life-year and was cost-effective for CGM-naive participants but at a lower level owing to the high cost of the CGM device.
IN PRACTICE:
“Personalization of goals and simplification of complex regimens can be combined with CGM use to improve management of type 1 diabetes in older adults,” the study authors wrote.
SOURCE:
The study was led by Medha N. Munshi, MD, Joslin Diabetes Center, Boston. It was published online in Diabetes Care.
LIMITATIONS:
The study included a relatively small sample size and an ethnically homogeneous and highly educated cohort, which may have limited the generalizability of its findings. Additionally, the study did not measure adherence to individual simplification strategies, which may have hindered the quantification of behavioral changes.
DISCLOSURES:
This study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health. Two authors declared serving as consultants for pharmaceutical companies.

Beyond Scope Creep: Why Physicians and PAs Should Come Together for Patients
Over the past few years, many states have attempted to address the ongoing shortage of healthcare workers by introducing new bills to increase the scope of practice for nurse practitioners (NPs) and physician assistants (PAs). The goal of each bill was to improve access to care, particularly for patients who may live in areas where it’s difficult to find a doctor.
In response, the American Medical Association (AMA) launched a targeted campaign to fight “scope creep.” Their goal was to gain the momentum necessary to block proposed legislation to modify or expand the practice authority of nonphysicians, including PAs. A spokesperson for the organization told this news organization that the AMA “greatly values and respects the contributions of PAs as important members of the healthcare team” but emphasized that they do not have the same “skill set or breadth of experience of physicians.”
As such, the AMA argued that expanded practice authority would not only dismantle physician-led care teams but also ultimately lead to higher costs and lower-quality patient care.
The AMA has since launched a large-scale advocacy effort to fight practice expansion legislation — and has a specific page on its website to highlight those efforts. In addition, they have authored model legislation, talking points for AMA members, and a widely read article in AMA News to help them in what they call a “fight for physicians.”
These resources have also been disseminated to the greater healthcare stakeholder community.
Marilyn Suri, PA-C, chief operating officer and senior executive for Advanced Practice Professional Affairs at Vincenzo Novara MDPA and Associates, a critical care pulmonary medicine practice in Miami, Florida, said she found the AMA’s campaign to be “very misleading.”
“PAs are created in the image of physicians to help manage the physician shortage. We are trained very rigorously — to diagnose illness, develop treatment plans, and prescribe medications,” she said. “We’re not trying to expand our scope. We are trying to eliminate or lessen barriers that prevent patients from getting access to care.”
Suri is not alone. Last summer, the American Academy of Physician Associates (AAPA) requested a meeting with the AMA to find ways for the two organizations to collaborate to improve care delivery — as well as find common ground to address issues regarding patient access to care. When the AMA did not respond, the AAPA sent a second letter in September 2024, reiterating their request for a meeting.
That correspondence also included a letter, signed by more than 8000 PAs from across the country, calling for an end to what the AAPA refers to as “damaging rhetoric,” as well as data from a recent survey of PAs regarding the fallout of AMA’s scope creep messaging.
Those survey results highlighted that the vast majority of PAs surveyed feel that the AMA is doing more than just attacking proposed legislation: They believe the association is negatively influencing patients’ understanding of PA qualifications, ultimately affecting their ability to provide care.
“The campaign is unintentionally harming patients by suggesting we are doing more than what we are trained to do,” said Elisa Hock, PA-C, a behavioral health PA in Texas. “And when you work in a place with limited resources, medically speaking — including limited access to providers — this kind of campaign is really detrimental to helping patients.”
Lisa M. Gables, CEO of the AAPA, said the organization is “deeply disappointed” in the AMA’s lack of response to their letters thus far — but remains committed to working with the organization to bring forward new solutions to address healthcare’s most pressing challenges.
“AAPA remains committed to pushing for modernization of practice laws to ensure all providers can practice medicine to the fullest extent of their training, education, and experience,” she said. “That is what patients deserve and want.”
Hock agreed. She told this news organization that the public is not always aware of what PAs can offer in terms of patient care. That said, she believes newer generations of physicians understand the value of PAs and the many skills they bring to the table.
“I’ve been doing this for 17 years, and it’s been an uphill battle, at times, to educate the public about what PAs can and can’t do,” she explained. “To throw more mud in the mix that will confuse patients more about what we do doesn’t help. Healthcare works best with a team-based approach. And that team has been and always will be led by the physician. We are aware of our role and our limitations. But we also know what we can offer patients, especially in areas like El Paso, where there is a real shortage of providers.”
With a growing aging population — and the physician shortage expected to increase in the coming decade — Suri hopes that the AMA will accept AAPA’s invitation to meet — because no one wins with this kind of healthcare infighting. In fact, she said patients will suffer because of it. She hopes that future discussions and collaborations can show providers and patients what team-based healthcare can offer.
“I think it’s important for those in healthcare to be aware that none of us work alone. Even physicians collaborate with other subspecialties, as well as nurses and other healthcare professionals,” said Suri.

Many Hurdles Exist to Treating Lung Cancer With CAR T Cells
These hurdles include finding the right targets, minimizing the risks of the treatment, and reducing the enormous burdens getting these therapies places on patients.
“Precision immunotherapy,” or unleashing the immune system in a highly specific manner, “is obviously, in a way, a holy grail” in lung cancer, said Martin Forster, MD, PhD, who cochaired a session on the topic at the World Conference on Lung Cancer (WCLC) 2024.
He underlined, however, that “immunology is very complex, as is cancer biology,” and consequently, there are different avenues being explored, including CAR T-cell therapies, T-cell receptor therapies, and tumor-infiltrating lymphocytes, among others.
Antibody technology is also being harnessed to target chemotherapy, via antibody-drug conjugates, noted Forster, who is clinical lead of the early phase clinical trials programme at University College London in England.
Moreover, investigators are looking at combining various therapies, such as immune checkpoint inhibitors with T cell–engaging approaches.
He highlighted, however, that the ideal target for these approaches is something that is recognized by the immune system as being foreign, but is found within the cancer, “and you also want it ideally to be in all of the cancer cells.”
A good example is a clonal change, meaning an early evolutionary genetic alteration in the tumor that is present in all the cells, Forster said.
Identifying the Right Target
“One of the big challenges in all forms of targeted immunotherapy is around selecting the target and developing the right product for the right target,” Forster emphasized.
“This concept works really well in hematological malignancies” but is “proving to be more challenging to deliver within solid malignancies,” he added.
“The reason why so many lung tumors are resistant to immunotherapy is because they ‘re immunologically cold,” Roy Herbst, MD, PhD, Department of Medical Oncology, Yale Comprehensive Cancer Center, New Haven, Connecticut, said in an interview.
“There are no T cells in the tumor,” he explained, so it “doesn’t really matter how much you block checkpoint inhibitors, you still have to have a T cell in there in order to have effect.”
To overcome this problem CAR T-cell therapies are engineered to target a tumor, Herbst continued, but that “is a little hard in lung cancer because you need to have a unique antigen that’s on a lung tumor that’s not present on normal cells.”
Charu Aggarwal, MD, MPH, Leslye M. Heisler Associate Professor for Lung Cancer Excellence, Penn Medicine, Philadelphia, Pennsylvania, agreed, saying that there is “a lot of excitement with CAR T-cell therapies, and the promise of cure,” but “the biology is not as simple as we think.”
“For example, it’s not as simple as CD20 or CD19 targeting,” she said in an interview. “Most of the antigens that are being targeted in the solid tumor world, unfortunately, are also expressed on normal tissue. So there is always this potential for toxicity.”
A Question of Time
Another aspect of CAR T-cell therapy that is proving difficult is its delivery.
Forster outlined that the process involves first leukapheresis, in which T cells are obtained from a blood draw. These are then genetically modified to express chimeric antigen receptors before being multiplied in the laboratory and introduced to the patient.
This process can take several weeks, during which patients may require bridging treatment, such as chemotherapy or radiotherapy, to keep their cancer under control. “Sometimes, patients with solid tumors who are in later lines of therapy may not have the luxury of time to be able to wait for all of these steps,” Aggarwal said.
There is also the question of whether a bespoke treatment can be scaled up so that it can be delivered to more patients in a more timely manner.
“There are certainly lessons to be learned from use of off-the-shelf CAR T-cell products” in hematologic malignancies, she noted, “but we’re just not there yet in lung cancer.”
Life-Threatening Toxicities
To improve the chances of engraftment when the CAR T cells are introduced, patients will require prior lymphodepletion with chemotherapy.
This, Forster said, is a “relatively intensive part of treatment.” However, “if you just give immune cells to somebody, when the host body is already full of immune cells,” the CAR T cells are unlikely to engraft, and “so you need to create space for those cells to develop.”
“What you want is not an immediate effect” but rather an immune “memory” that will give an ongoing benefit, he underscored.
Many patients will need to stay in the hospital one or more nights “because when you bring T cells to a tumor, you get cytokine release syndrome [CRS],” Herbst said. This can cause hypotension, fever, and chills, similar to a viral response.
“So patients can get sick,” which in turn requires treatment and follow-up. That puts a “big burden on the health system” and is a major issue, Herbst said.
Patients are also at a risk for “significant neurotoxicity,” said session cochair Amy Moore, PhD, vice president of Global Engagement and Patient Partnerships, LUNGevity Foundation, Chicago. This, alongside CRS, “can be life threatening for our patients.”
Lengthy hospital stays also have a psychosocial impact on the patient and their quality of life, she emphasized, especially when they are treated in a center far away from family and loved ones.
“We’ve also heard anecdotally some reports recently of secondary malignancies” with CAR T cell and other therapies, and that’s something that needs to be monitored as more patients go on these treatments, she said.
‘At What Cost’ to Patients?
The difficulties faced by patients in receiving CAR T-cell therapy go far beyond the practicalities of generating the cells or the risks associated with lymphodepletion, however.
“These therapies are extraordinarily expensive,” although that has to be weighed against the cost of years of ongoing treatment with immunotherapy, Moore said.
Moreover, as CAR T-cell therapies are a “last resort” option, patients have to “exhaust all other treatments” before being eligible, she continued. There’s significant prior authorization challenges, which means patients “have to go through many hurdles before they can qualify for treatment with these therapies.”
This typically involves having numerous laboratory tests, which can add up to out-of-pocket expenses for patients often reaching tens of thousands of dollars, Moore said.
Another issue is that they must be administered in certified treatment centers, and there are a limited number of those in the United States, she added.
This increases the risk of heightening disparities, as patients are “forced to travel, seek lodging, and have meal expenses,” and the costs “are not trivial,” Moore underlined. “It can rack up quickly and mount to $10,000 or more.”
For physicians, there are difficulties in terms of the logistics of following up with those patients who need to be treated at centers on the other side of the country, uncertainties around reimbursement, and restrictions in terms of staff time and resources, among others.
“I’m as excited as you are at the science,” but it is the implementation that is at issue, Moore said. In other words, there is the offer of a cure with CAR T-cell therapy, but “at what cost?”
“For patients, these considerations are real and they’re significant” and “we have to ensure that what we’re doing is in service of people with cancer,” she emphasized.
No funding was declared. Aggarwal declared relationships with Genentech, Celgene, AstraZeneca, Daiichi Sankyo, Turning Point, Janssen, Pfizer, Lilly, Merck, Regeneron/Sanofi, Eisai, BeiGene, Boehringer Ingelheim, Blueprint Genetics, and Shionogi. Forster declared relationships with AstraZeneca, Boehringer Ingelheim, Merck, MSD, Achilles, Amgen, Bayer, Bristol-Myers Squibb, Celgene, EQRx, GSK, Immutep, Janssen, Merck, Oxford Vacmedix, PharmaMar, Roche, Takeda, Syncorp, Transgene, and Ultrahuman. Moore declared no relevant financial relationships.

“So patients can get sick,” which in turn requires treatment and follow-up. That puts a “big burden on the health system” and is a major issue, Herbst said.
Patients are also at a risk for “significant neurotoxicity,” said session cochair Amy Moore, PhD, vice president of Global Engagement and Patient Partnerships, LUNGevity Foundation, Chicago. This, alongside CRS, “can be life threatening for our patients.”
Lengthy hospital stays also have a psychosocial impact on the patient and their quality of life, she emphasized, especially when they are treated in a center far away from family and loved ones.
“We’ve also heard anecdotally some reports recently of secondary malignancies” with CAR T cell and other therapies, and that’s something that needs to be monitored as more patients go on these treatments, she said.
‘At What Cost’ to Patients?
The difficulties faced by patients in receiving CAR T-cell therapy go far beyond the practicalities of generating the cells or the risks associated with lymphodepletion, however.
“These therapies are extraordinarily expensive,” although that has to be weighed against the cost of years of ongoing treatment with immunotherapy, Moore said.
Moreover, as CAR T-cell therapies are a “last resort” option, patients have to “exhaust all other treatments” before being eligible, she continued. There’s significant prior authorization challenges, which means patients “have to go through many hurdles before they can qualify for treatment with these therapies.”
This typically involves having numerous laboratory tests, which can add up to out-of-pocket expenses for patients often reaching tens of thousands of dollars, Moore said.
Another issue is that they must be administered in certified treatment centers, and there are a limited number of those in the United States, she added.
This increases the risk of heightening disparities, as patients are “forced to travel, seek lodging, and have meal expenses,” and the costs “are not trivial,” Moore underlined. “It can rack up quickly and mount to $10,000 or more.”
For physicians, there are difficulties in terms of the logistics of following up with those patients who need to be treated at centers on the other side of the country, uncertainties around reimbursement, and restrictions in terms of staff time and resources, among others.
“I’m as excited as you are at the science,” but it is the implementation that is at issue, Moore said. In other words, there is the offer of a cure with CAR T-cell therapy, but “at what cost?”
“For patients, these considerations are real and they’re significant” and “we have to ensure that what we’re doing is in service of people with cancer,” she emphasized.

Moore declared no relevant financial relationships.
These hurdles include finding the right targets, minimizing the risks of the treatment, and reducing the enormous burdens getting these therapies places on patients.
“Precision immunotherapy,” or unleashing the immune system in a highly specific manner, “is obviously, in a way, a holy grail” in lung cancer, said Martin Forster, MD, PhD, who cochaired a session on the topic at the World Conference on Lung Cancer (WCLC) 2024.
He underlined, however, that “immunology is very complex, as is cancer biology,” and consequently, there are different avenues being explored, including CAR T-cell therapies, T-cell receptor therapies, and tumor-infiltrating lymphocytes, among others.
Antibody technology is also being harnessed to target chemotherapy, via antibody-drug conjugates, noted Forster, who is clinical lead of the early phase clinical trials programme at University College London in England.
Moreover, investigators are looking at combining various therapies, such as immune checkpoint inhibitors with T cell–engaging approaches.
He highlighted, however, that the ideal target for these approaches is something that is recognized by the immune system as being foreign, but is found within the cancer, “and you also want it ideally to be in all of the cancer cells.”
A good example is a clonal change, meaning an early evolutionary genetic alteration in the tumor that is present in all the cells, Forster said.
Identifying the Right Target
“One of the big challenges in all forms of targeted immunotherapy is around selecting the target and developing the right product for the right target,” Forster emphasized.
“This concept works really well in hematological malignancies” but is “proving to be more challenging to deliver within solid malignancies,” he added.
“The reason why so many lung tumors are resistant to immunotherapy is because they ‘re immunologically cold,” Roy Herbst, MD, PhD, Department of Medical Oncology, Yale Comprehensive Cancer Center, New Haven, Connecticut, said in an interview.
“There are no T cells in the tumor,” he explained, so it “doesn’t really matter how much you block checkpoint inhibitors, you still have to have a T cell in there in order to have effect.”
To overcome this problem CAR T-cell therapies are engineered to target a tumor, Herbst continued, but that “is a little hard in lung cancer because you need to have a unique antigen that’s on a lung tumor that’s not present on normal cells.”
Charu Aggarwal, MD, MPH, Leslye M. Heisler Associate Professor for Lung Cancer Excellence, Penn Medicine, Philadelphia, Pennsylvania, agreed, saying that there is “a lot of excitement with CAR T-cell therapies, and the promise of cure,” but “the biology is not as simple as we think.”
“For example, it’s not as simple as CD20 or CD19 targeting,” she said in an interview. “Most of the antigens that are being targeted in the solid tumor world, unfortunately, are also expressed on normal tissue. So there is always this potential for toxicity.”
A Question of Time
Another aspect of CAR T-cell therapy that is proving difficult is its delivery.
Forster outlined that the process involves first leukapheresis, in which T cells are obtained from a blood draw. These are then genetically modified to express chimeric antigen receptors before being multiplied in the laboratory and introduced to the patient.
This process can take several weeks, during which patients may require bridging treatment, such as chemotherapy or radiotherapy, to keep their cancer under control. “Sometimes, patients with solid tumors who are in later lines of therapy may not have the luxury of time to be able to wait for all of these steps,” Aggarwal said.
There is also the question of whether a bespoke treatment can be scaled up so that it can be delivered to more patients in a more timely manner.
“There are certainly lessons to be learned from use of off-the-shelf CAR T-cell products” in hematologic malignancies, she noted, “but we’re just not there yet in lung cancer.”
Life-Threatening Toxicities
To improve the chances of engraftment when the CAR T cells are introduced, patients will require prior lymphodepletion with chemotherapy.
This, Forster said, is a “relatively intensive part of treatment.” However, “if you just give immune cells to somebody, when the host body is already full of immune cells,” the CAR T cells are unlikely to engraft, and “so you need to create space for those cells to develop.”
“What you want is not an immediate effect” but rather an immune “memory” that will give an ongoing benefit, he underscored.
Many patients will need to stay in the hospital one or more nights “because when you bring T cells to a tumor, you get cytokine release syndrome [CRS],” Herbst said. This can cause hypotension, fever, and chills, similar to a viral response.
“So patients can get sick,” which in turn requires treatment and follow-up. That puts a “big burden on the health system” and is a major issue, Herbst said.

Vonoprazan Offers PPI Alternative for Heartburn with Non-Erosive Reflux
according to investigators.
Benefits of vonoprazan were seen as soon as the first day of treatment and persisted through the 20-week extension period, lead author Loren Laine, MD, AGAF, of Yale School of Medicine, New Haven, Connecticut, and colleagues reported.
“A potential alternative to PPI therapy is a potassium-competitive acid blocker, a new class of antisecretory agents that provide more potent inhibition of gastric acid secretion than PPIs,” the investigators wrote in Clinical Gastroenterology and Hepatology.
While a small observational study found that 18 out of 26 patients (69%) with PPI-resistant NERD had improved symptoms with vonoprazan, subsequent randomized trials in Japan failed to meet their primary endpoints, Laine and colleagues noted. The present randomized trial was therefore conducted to determine how vonoprazan might help a US patient population.
The study involved 772 patients who reported heartburn at least 4 days per week during screening, but without erosive esophagitis on endoscopy. Participants were randomized into three groups: placebo, vonoprazan 10 mg, or vonoprazan 20 mg. These protocols were administered for 4 weeks, followed by a 20-week extension, in which placebo patients were rerandomized to receive one of the two vonoprazan dose levels.
The primary endpoint was the percentage of days without daytime or nighttime heartburn (24-hour heartburn-free days) during the initial 4-week treatment period. The secondary endpoint, assessed during the same timeframe, was percentage of days without need for a rescue antacid.
In the 4-week placebo-controlled period, patients treated with vonoprazan 10 mg and 20 mg showed a significant improvement in heartburn-free days, compared with placebo. The percentage of 24-hour heartburn-free days was 27.7% in the placebo group vs 44.8% in the 10-mg vonoprazan group (least squares mean difference 17.1%; P < .0001) and 44.4% in the 20 mg vonoprazan group (least squares mean difference 16.7%; P < .0001).
Benefits of vonoprazan were seen as early as the first day of treatment, with 8.3% and 11.6% more patients in the 10-mg and 20-mg groups, respectively, experiencing a heartburn-free day, compared with placebo. By day 2, these differences increased to 18.1% and 23.2%, respectively.
The percentage of days without rescue antacid use was also significantly higher in both vonoprazan groups. Patients in the 10 mg and 20 mg groups had 63.3% and 61.2% of days without antacid use, respectively, compared with 47.6% in the placebo group (P < .0001 for both comparisons).
These benefits persisted throughout the 20-week extension period, with similar percentages of heartburn-free days across all groups. Mean percentages of 24-hour heartburn-free days ranged from 61% to 63% in the extension phase, while median percentages spanned 76%-79%.
Adverse events were infrequent and comparable across all groups. The most common adverse event was nausea, occurring slightly more frequently in the vonoprazan groups (2.3% in the 10-mg group and 3.1% in the 20-mg group) vs placebo (0.4%). Serious adverse events were rare and were deemed unrelated to treatment. No new safety signals were identified during the 20-week extension period. Increases in serum gastrin levels, a marker of acid suppression, returned to near baseline after discontinuation of vonoprazan.
“In conclusion, the potassium-competitive acid blocker vonoprazan was efficacious in reducing heartburn symptoms in patients with NERD, with the benefit appearing to begin as early as the first day of therapy,” Laine and colleagues wrote.
In July 2024, the Food and Drug Administration approved vonoprazan for treating heartburn in patients with nonerosive gastroesophageal reflux disease.This study was funded by Phathom Pharmaceuticals. The investigators disclosed additional relationships with Takeda, Medtronic, Carnot, and others.
Proton pump inhibitors (PPIs) have revolutionized the treatment of gastroesophageal reflux disease (GERD). One might ask what the reason would be to challenge this giant of the pharmacopeia with another medication for GERD.
In this important study by Laine et al, vonoprazan is expectedly efficacious in treating nonerosive GERD (NERD) but notably less so when compared with the authors’ trial for erosive GERD. This is not surprising owing to the multiple and common acid independent etiologies of NERD, such as esophageal hypersensitivity. The high placebo response supports this. Two notable results, however, merit emphasis in potential advantages over PPIs.
First, vonoprazan is effective at day 1 of therapy by eliminating the need for loading. Second, nocturnal reflux, a purer form of GERD, is better controlled with a morning dose of vonopazan mitigating against nocturnal acid breakthrough and the need for twice-daily dosing with PPIs and/or addition of an H2 antagonist. These results by no means advocate for replacement of PPIs with PCABs, but at least suggest specific populations of GERD patients who may specifically benefit from PCAB use. The study also indirectly emphasizes that careful selection of NERD patients whose GERD symptoms are predominantly caused by increased esophageal acid exposure are the most appropriate candidates. The ultimate answer as to where vonoprazan will be used in our practice is evolving.

Semaglutide a Potential Treatment Option for Opioid Use Disorder?
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.

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.

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.

Our Biggest Turnout Ever for Advocacy Day!
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.
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!

Artificial Intelligence Helps Diagnose Lung Disease in Infants and Outperforms Trainee Doctors
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.
“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.

Pediatricians Must Prepare for Impact on Allergies and Asthma From Climate Change
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.
, 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.

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.

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.

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.
