Detailní popis
Open-air burn pits used during military operations in Southwest Asia and other deployment settings have been associated with complex airborne exposures and long-term health concerns, including respiratory, cardiovascular, neurologic, immune, and oncologic sequelae. Prior studies have relied largely on self-report, clinical symptoms, or limited physiologic testing, and there remains a need for objective biologic markers of exposure-associated effects. Project PHOENIX is intended to generate a standardized, high-dimensional biospecimen and data resource that can support biomarker discovery, mechanistic modeling, and future translational research.
Participants will enroll remotely. Screening, consent, and questionnaire completion will occur electronically through a secure eConsent platform. After consent, participants will complete a baseline study visit that includes eligibility confirmation, collection of demographic and exposure history and venipuncture.
The exposed cohort will include former U.S. Service Members with prior deployment to locations with known burn pit operations. The control cohort will include comparable U.S. Service Members/Veterans without known burn pit deployment exposure. Planned analyses include between-group comparisons across multi-omic and cellular-function domains, assessment of exposure intensity/duration relationships, and development of integrated predictive models using statistical and machine-learning methods. Optional annual re-contact for up to 5 years may be used to update health status and obtain additional blood specimens.

Intervence / Léčba |
|---|---|
|
Prior Burn Pit Exposure
Former U.S. Service Members with prior deployment to locations with known burn pit operations, based on self-report and available service/registry confirmation when feasible.
Participants will complete study questionnaires, brief health assessments, and one-time blood collection for multi-omic, cellular, and functional analyses.
Optional future re-contact may occur.
|
History of deployment-related exposure to environments with known open-air burn pit operations, characterized by self-reported deployment/exposure history and corroborating information when available.
|
|
Unexposed Control
Former U.S. Service Members/Veterans without known deployment-related burn pit exposure, frequency-matched at the group level to the exposed cohort on selected demographic/service characteristics.
Participants will complete study questionnaires, brief health assessments, and one-time blood collection for comparative analyses.
Optional future re-contact may occur.
|
No known deployment-related burn pit exposure based on participant report and available service history.

Comparison of whole blood transcriptomic profiles using RNA sequencing.
Differential gene expression will be quantified using normalized read counts and modeled as log2 fold-change between cohorts.

Optional longitudinal change in composite multi-domain health and biomarker score
Časové okno: Exploratory follow-up of health status updates and, where applicable, repeat blood-based measures among participants who consent to longitudinal re-contact. Baseline and annually up to 60 months.
|
A composite score integrating patient-reported outcomes and selected blood-based biomarkers (e.g., inflammatory markers and omics-derived features), summarized as a standardized z-score.
Change from baseline will be assessed among participants with follow-up data.

Exploratory follow-up of health status updates and, where applicable, repeat blood-based measures among participants who consent to longitudinal re-contact. Baseline and annually up to 60 months.
