Design of a randomized tobacco cessation trial among FDNY World Trade Center responders in a lung cancer screening program.

BACKGROUND: Cigarette smoking remains the leading preventable cause of death, posing heightened risks for vulnerable populations. World Trade Center (WTC) disaster responders face an elevated burden of respiratory diseases, and despite access to an evidence-based tobacco cessation program, a subset continues to smoke cigarettes. Treatment engagement remains a critical barrier, as many people who smoke fail to enroll in or adhere to programs, particularly when participation requires decisions to actively opt-in to treatment. This randomized controlled trial integrates tobacco treatment into an

Performance evaluation of commercially available non-regulatory instruments and sensors in smoke for PM, CO, CO2, NO2, and SO2.

Wildland fire smoke can severely degrade downwind air quality and impact responding firefighters and the public. Accurate and timely monitoring of particulate matter (PM) and gaseous pollutants around wildland fires are needed to support management activities like protecting responders and the public from the health and safety hazards of wildland fire smoke. This study systematically evaluates the performance of commercially available, non-regulatory PM and gas instruments/sensors under controlled wildland fire smoke conditions. We assessed accuracy, precision, and linearity by comparing instr…

Deficiency of spns1 exacerbates per- and polyfluoroalkyl substances mediated hepatic toxicity and steatosis in zebrafish (Danio rerio).

Per- and polyfluoroalkyl substances (PFAS) are man-made long-lasting chemical compounds that are found in everyday household items. Today they occur in the environment as a major group of pollutants. These compounds are broadly used in commercial product preparation such as, for food packaging, nonstick coatings, and firefighting foam. In humans, PFAS can cause immune disorders, impaired fetal development, abnormal skeletal tissue development, osteoarthritis, thyroid dysfunctions, cholesterol changes, affect insulin regulation and lipid metabolism, and are also involved in the development of f

Nondestructive Quantitative Evaluation of Yarns and Fabrics and Determination of Contact Area of Fabrics Using the X-ray Microcomputed Tomography System for Skin-Textile Friction Analysis.

In different mechanical conditions, repetitive friction in combination with pressure, shear, temperature, and moisture leads to skin discomfort and imposes the risks of developing skin injuries such as blisters and pressure ulcers, frequently reported in athletes, military personnel, and in people with compromised skin conditions and/or immobility. Textiles next to skin govern the skin microclimate, have the potential to influence the mechanical contact with skin, and contribute to skin comfort and health. The adhesion-friction theory suggests that contact area is a critical factor to influenc

Estimating the number of airports potentially contaminated with perfluoroalkyl and polyfluoroalkyl substances from aqueous film forming foam: A Canadian example.

Assessing the extent to which emerging contaminants (ECs) such as perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been released into the environment is one of the foundations for developing effective management and remediation strategies for impacted sites. PFAS are known to have caused the contamination of soil, groundwater, and surface water as a result of aqueous film forming foam (AFFF) being accidentally or intentionally released into the environment. To date, the scope of the issue has not been evaluated in Canada. In this study we developed a framework, in the form of a decisi

Review of chamber design requirements for testing of personal protective clothing ensembles.

This review focuses on the physical requirements for conducting ensemble testing and describes the salient issues that organizations involved in the design, test, or certification of personal protective equipment (PPE) and protective clothing ensembles need to consider for strategic planning. Several current and proposed PPE ensemble test practices and standards were identified. The man-in-simulant test (MIST) is the primary procedure used by the military to evaluate clothing ensembles for protection against chemical and biological warfare agents. MIST has been incorporated into the current ed

OBJECTIVE: To assess the accuracy of the AbC-19 Rapid Test lateral flow immunoassay for the detection of previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. DESIGN: Test accuracy study. SETTING: Laboratory based evaluation. PARTICIPANTS: 2847 key workers (healthcare staff, fire and rescue officers, and police officers) in England in June 2020 (268 with a previous polymerase chain reaction (PCR) positive result (median 63 days previously), 2579 with unknown previous infection status); and 1995 pre-pandemic blood donors. MAIN OUTCOME MEASURES: AbC-19 sensitivity

Exploring First Responders' Use and Perceptions on Continuous Health and Environmental Monitoring.

First responders lose their lives in the line of duty each year, and many of these deaths result from strenuous physical exertion and exposure to harmful environmental agents. Continuous health monitoring may detect diseases and alert the first responder when vital signs are reaching critical levels. However, continuous monitoring must be acceptable to first responders. The purpose of this study was to discover first responders' current use of wearable technology, their perceptions of what health and environmental indicators should be monitored, and who should be permitted to monitor them. The

Polar Life Pod Cooling Efficacy When Small Volumes of Water are Available to Treat Exercise-Induced Hyperthermia.

IntroductionCold-water immersion is the standard of care for treating exertional heatstroke (EHS). The Polar Life Pod (PLP; Polar Products Inc, Stow, OH), a body-bag-like device, is a novel, portable cold-water immersion device with excellent cooling rates (>0.18°C·min-1) when 151 to 208 L of water are used to treat hyperthermia. Unfortunately, these water volumes are not always available to treat EHS (eg, wilderness firefighting). Little research has examined whether the PLP with small water volumes meets expert recommendations for acceptable (ie, 0.08-0.15°C·min-1) or ideal cooling rates (ie
