(Press-News.org) DENVER — Years after the opioid epidemic began in the mid-1990s, emergency medical services are seeing increases in emergency calls for pre-teens and adolescents, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition at the Colorado Convention Center from Sept. 26-30.
The research, “EMS Calls for Pediatric Patients Ages 11-18 years with Opioid Exposures using NEMSIS data,” examined calls for services due to suspected pediatric opioid exposure reported to the National Emergency Medical Services Information System, which tracks emergency medical service data from across the United States. Authors reviewed the data from 2019 through 2023, breaking it down into two categories: middle school aged children and high school aged teens.
Opioid exposure calls increased nationally each year of the study for middle-school aged children, rising from 255 calls in 2019 to 553 in 2023. Teenagers fared slightly better with drops in emergency opioid exposure calls after 2022.
Research author Sonia Lam, DO and pediatric emergency medicine fellow, said the new opioid exposure trends are causing concern among health professionals.
“Opioid exposures in middle- and-high school aged students are a growing public health concern. The medical community and legislative authorities have an opportunity and obligation to enact policies to decrease risk to these vulnerable kids,” Dr. Lam said.
Dr. Lam said that demographics varied by group, with females outnumbering males in the middle school age group, while the reverse pattern was true for the older group. Younger children also tend to present with significantly higher levels of acuity compared to older children
Authors suggest that targeted interventions for prevention of drug use disorders in children should be informed by how use varies with children’s age and sex.
The authors did not receive financial support for this research.
Dr. Lam is scheduled to present the research, which is below, from 2:15 p.m. to 2:30 p.m. MDT on Friday, Sept. 26, in the Colorado Convention Center, Meeting Room 108/110/112. To request an interview with the authors, contact Brianna Mortensen at BMortensen@salud.unm.edu.

Abstract Title: EMS Calls for Pediatric Patients Ages 11-18 years with Opioid Exposures using NEMSIS data
Sonia Lam
The opioid crisis has long been an issue nationwide with the use of prescription opioids and heroin for pain management and recreational use. Poisoning, including drug overdose, is now the 3rd leading cause of death in U.S. children ages 1 to 19 years, after firearm injury and motor vehicle crashes. The purpose of this study is to compare the trend of opioid exposures among children in two age groups: pre-teenage, and teenage.
This retrospective study uses the National Emergency Medical Services Information System (NEMSIS) data set from the years 2019 to 2023. NEMSIS is a national system used to collect, store and share EMS data. To identify opioid exposures, the NEMSIS database includes ICD-10 codes for chief complaint (subsets of external cause codes F11 and T40) and whether naloxone was administered. Age groups were categorized as middle school (11-13 years) and high school (14–18 years). The two groups were compared for trends over time, sex ratio, and acuity level (lower acuity, emergent, critical, or deceased). Chi-square analysis compared proportions, and linear regression is used for trend analysis.
EMS calls for opioid exposure increased every year among 11–13-year-olds, from 257 in 2019 to 560 in 2023. Among 14–18-year-olds, numbers increased from 2019 (3,904) through 2022 (7,392), then decreased (6,960). In Figure 1, we present the proportion of overall EMS calls for each age group for opioid related complaints based on number of NEMSIS calls increased each year. The majority of patients in the middle school group were female (61.1%), while in the high school group, females were a minority of patients (40.6%) (p=0.001). Acuity level also varied by age group (p=0.001). In five years, there were acuity data for 1,429 calls in the middle school group and 21,340 in the high school group. A higher proportion of the middle school group presented as critical (24.5%) than the older age group (15.7%) (p=0.001) (Figure 2).
Patterns of EMS calls for middle school and high school children vary significantly. Younger children have a more persistent pattern of increasing calls over time, they are disproportionately female, and they are more likely to present with critical acuity than older children. These differences suggest targeted interventions for prevention and treatment of drug use disorders in children.
Figure 1. Rate of opioid calls per total number of calls by age group and year, NEMSIS data, 2019-2023. To compare the rate of change over time between the two age groups on one graph, we used the number of total NEMSIS calls for all reasons for each age group by year to calculate an annual rate by age group and year.

DENVER — The COVID-19 pandemic resulted in students being less engaged and open about sexual education when compared with other middle school classes, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition at the Colorado Convention Center from Sept. 26-30.
Researchers taught two different groups of 7th grade students about their sexual health over an 8-lesson course – once during the 2018-2019 school year and again in the 2023-2024 school year. After the courses were completed, each group of students was given a questionnaire on what they ...
DENVER — An analysis of data from over 1.2 million pregnant individuals found that those who received a COVID-19 vaccination had a 58% lower risk of being infected with the virus, as well as a lower risk of experiencing a stillbirth or preterm birth, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition at the Colorado Convention Center from Sept. 26-30.
For the study, “Safety and Efficacy of Maternal COVID-19 Vaccination During Pregnancy: Umbrella Review & Meta-Analyses,” the author conducted a systematic search of PubMed, Scopus, Web of Science, and Embase from Jan. ...
Strong Northern Lights-like activity is the standout feature of today’s weather report, which is coming at you from a strange, extrasolar world, instead of a standard TV studio. That is thanks to astronomers from Trinity College Dublin, who used the NASA/ESA/CSA James Webb Space Telescope to take a close look at the weather of a toasty nearby rogue planet, SIMP-0136.
The exquisite sensitivity of the instruments on board the space-based telescope enabled the team to see minute changes in brightness of the planet as it rotated, which were used to track changes in temperature, cloud cover and chemistry.

Bacteria are constantly moving by help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like “speaking to each other”, and thus acquire new abilities through the exchange of DNA materials. These motility organs play important roles in DNA uptake to exchange genetic information between different bacteria, allowing what’s so-called genomic plasticity. Therefore, bacterial motility organs contribute to bacterial pathogenicity, colonizing ...
Remote sensing object detection is a rapidly growing field in artificial intelligence, playing a critical role in advancing the use of Unmanned Aerial Vehicles (UAVs) for real-world applications such as disaster response, urban planning, and environmental monitoring. Yet, designing models that balance both high accuracy and fast, lightweight performance remains a challenge. UAVs often capture images where objects appear in different sizes, angles, and lighting conditions, all while operating on devices with limited computing power. This creates the need for innovative ...
In recent years, measles has made a resurgence globally. In England, 2024 saw the highest number of confirmed measles cases since 2012, resulting in the declaration of a national incident. One reason for this is falling vaccination rates, prompted — to some extent — by the success of established measles vaccination programmes, which has reduced public awareness of the contagiousness and potentially serious complications of measles.
Measles is often erroneously thought to be a childhood disease. Yet approximately one-third of the 2,911 cases confirmed in England in 2024, and six of the seven measles-related deaths since 2000, were ...
Yuanyuan Wang and Wenlei Zhu's group at Nanjing University, China, and Yuehe Lin at Washington State University, USA, recently reported the development of a three-dimensional ordered mesoporous carbon skeleton with Ni single atom support using the superlattice blotting strategy for efficient electrocatalytic hydrogen production. Firstly, they derived an ordered mesoporous framework based on finite element simulation, which is of great significance for promoting uniform gas distribution, stabilizing the gas-liquid-solid interface of nanoscale hydrophilic surfaces, and enhancing mass transfer kinetics. Then, the proposed superlattice blotting ...
The Biochar Myth-Buster
We’ve all heard the story: biochar cleans water by adsorbing pollutants—trapping them like a sponge. Or, in fancier setups, it acts as a catalyst to help oxidants like hydrogen peroxide break down toxins. But Dr. Gao’s team asked a bold question: What if biochar can degrade pollutants all by itself? Turns out—it can. And it’s been doing it quietly all along.
The Electron Ninja: Biochar’s Secret Power
The secret lies in electron transfer—a natural ability of biochar that’s been overlooked for years. Think of it like this: instead of just catching a bad guy (adsorption), biochar can now take them ...
A sticky, toxic by-product that has long plagued renewable energy production may soon become a valuable resource, according to a new review published in Biochar.
When biomass such as crop residues, wood, or other organic matter is heated to produce clean energy and biochar, it also generates a thick liquid known as bio-tar. This tar easily clogs pipelines, damages equipment, and poses environmental risks if released into the atmosphere. For decades, researchers have sought ways to eliminate or neutralize it.
Now, a team led by scientists at the Chinese Academy of Agricultural Sciences argues that instead of being treated as waste, bio-tar can be converted into “bio-carbon”—a ...
