Perceptions of and Responses to Wildfire Smoke Among New York State Residents: A Cross-Sectional Study

International Journal of Environmental Research and Public Health, Journal Year: 2025, Volume and Issue: 22(2), P. 277 - 277

Exposure to wildfire smoke (WFS) is associated with detrimental physical and mental health. Periods of sustained WFS are predicted increase climate change, affecting populations globally. Using a retrospective cross-sectional study, we assessed perceptions responses in cohort New York State (NYS) residents Summer 2023. Data were collected using an online survey from October November Descriptive statistics summarized respondent experiences, while exploratory analyses identified high-risk chi-square t-tests. Our sample consisted 609 primarily healthy, white, well-educated individuals who spent most their time NYS during Of the 99% that reported experiencing WFS, 92% received 91% sought out WFS-related air quality information. While only 25% illness, 87% experienced at least one symptom frequently citing watery eyes (63%), irritated throat (50%), headaches (49%), women reporting symptoms more than men (89.1% vs. 81.6%; p = 0.034). A majority (93%) taking mitigation actions, including avoiding outdoor activities (75%) wearing masks (54%). results highlight widespread impacts wildfires 2023, nearly all respondents periods WFS.

The 2025 Los Angeles Wildfires and Outpatient Acute Healthcare Utilization

Published: March 15, 2025

Abstract January 2025 brought devastating wildfires to Los Angeles (LA) County, California, causing poor air quality, destroying homes and businesses, displacing thousands of people. We used electronic health record data from 3.7 million Kaiser Permanente Southern California members promptly determine if the LA Fires increased outpatient acute healthcare utilization. created exposure categories using maximum wildfire burn zone reached by an or Ventura County as 16, 2025. Highly-exposed resided in census tracts located <20km zones moderately-exposed lived ≥20km but within County. identified daily virtual care visits five categories: all-cause, cardiovascular, injury, neuropsychiatric, respiratory. conducted 2-stage interrupted time-series analyses machine-learning algorithms how much Across week following 7 ignitions, respiratory were 41% (95% empirical confidence interval [eCI]: 26%, 56%) higher 34% eCI: 17%, 52%) than expected highly- groups, respectively, totaling 3,221 excess visits.

Fine Particulate Matter From 2020 California Wildfires and Mental Health–Related Emergency Department Visits

JAMA Network Open, Journal Year: 2025, Volume and Issue: 8(4), P. e253326 - e253326

Published: April 4, 2025

Importance A growing body of research suggests that exposure to fine particulate matter (PM 2.5 ; particle size microns or smaller) may be associated with mental health outcomes. However, the potential impact wildfire-specific PM on remains underexplored. Objective To investigate whether emergency department (ED) visits for conditions, including all-cause and psychoactive substance use, nonmood psychotic disorders, anxiety, depression, other mood-affective disorders during extensive 2020 California wildfire season. Design, Setting, Participants This cross-sectional study used data ED from July December obtained Department Health Care Access Information (HCAI). Eligible participants were residents who presented an in conditions without COVID-19. The analyzed between 2020. Exposure Wildfire-specific (with up 7-day lags) based participants’ residential zip codes. Main Outcomes Measures Daily visit counts disease-specific (F00-F99) identified using International Statistical Classification Diseases Related Problems, Tenth Revision (ICD-10) codes at code tabulation areas. Results Between 2020, there 86 609 (median [IQR] patient age, 38 [27-54] years; 40 272 female [46.5%]; 10 657 Black [12.3%], 30 044 Hispanic [34.7%], 35 145 White [40.6%]). Visits included use (23 966 [27.6%]), (16 714 [19.3%]), anxiety (26 711 [30.8%]), depression (10 422 [12.0%]), (5338 [6.2%]). During peak months, median (IQR) daily concentration increased 11.9 (3.9-32.5) μg/m 3 . 10-μg/m increase was higher (cumulative relative risk [cRR] over lag 0-7 days, 1.08; 95% CI, 1.03-1.12), (cRR 1.15; 1.02-1.30), 1.29; 1.09-1.54), 0-4 1.06; 1.00-1.12). Subgroup analyses suggested smoke disproportionately among individuals (eg, depression: cRR 1.17; 1.03-1.32) young people (other disorders: 1.46; 1.08-1.98).

Ketamine-induced static and dynamic functional connectivity changes are modulated by opioid receptors and biological sex in rats

Neuropsychopharmacology, Journal Year: 2025, Volume and Issue: unknown

Published: April 19, 2025

Abstract Subanesthetic ketamine is currently used as a rapid-acting treatment for varied neuropsychiatric disorders. However, the mechanistic underpinnings of its therapeutic action remain unclear, and emerging clinical preclinical evidence highlights potential involvement opioid system. We pharmacological functional ultrasound imaging data acquired during after administration in male female rats pretreated with naltrexone, an receptor antagonist, or vehicle. found that ketamine-induced connectivity changes are modulated by blockade, these responses dependent on biological sex. Specifically, naltrexone sex-dependently altered patterns within medial prefrontal cortex (mPFC), key node brain’s default-mode network, between mPFC other nodes. Furthermore, produced opioid-dependent shift toward states increased dysconnectivity brain entropy only. Our findings warrant further investigation into neurophysiological sex-specific interactions receptors.

Evaluating estimation methods for wildfire smoke and their implications for assessing health effects

EarthArXiv (California Digital Library), Journal Year: 2024, Volume and Issue: unknown

Published: June 13, 2024

Growing wildfire smoke represents a substantial threat to air quality and human health in the US across much of globe. However, impact on remains imprecisely understood, due uncertainties both measurement population exposure dose-response functions linking health. Here, we compare daily smoke-related surface fine particulate matter (PM2.5) concentrations estimated using three approaches, including two chemical transport models (CTMs): GEOS-Chem Community Multiscale Air Quality (CMAQ), one machine learning (ML) model over contiguous 2020, historically active fire year. We study consequences these different approaches for estimating PM2.5 effects mortality. In western US, compared against measurements from Environmental Protection Agency (EPA) PurpleAir sensors, find that CTMs overestimate during extreme episodes by up 3-5 fold, while ML estimates are largely consistent with measurements. eastern where levels were lower show modestly better agreement develop calibration framework integrates CTM- ML-based yields outperform each individual approach. When combining county-level mortality rates, low-level but large discrepancies high-level methods. Our research highlights benefits costs estimation methods understanding impacts smoke, demonstrates importance bench-marking available
