Serum PFAS concentrations were not associated with increased cardiometabolic risk measures in this population of firefighters.

Examine atherosclerotic cardiovascular disease (ASCVD) risk scores by age and weight status in career firefighters.

Medical examinations for firefighters more than or equal to 40 years (n = 644) were examined. ASCVD 10-year risk scores were calculated from sex- and race-specific equations and were reported by three age (40 to 44.9, 45 to 49.9, more than or equal to 50 years) and weight (normal, overweight, obese) categories.

Mean risk scores were 1.8%, 3.5%, and 6.2% for firefighters 40 to 44.9, 45 to 49.9, and more than or equal to 50 years, respectively. The association of weight status with increased ASCVD risk was higher (P < 0.01) among older firefighters, where risk was 0.8% (95% confidence interval [CI] 0.6 to 1.1) and 2.3% (95% CI 2.0 to 2.6) among normal versus obese 40 to 44.9 year olds, and 4.1% (95% CI 3.1 to 5.3) and 7.8% (95% CI 6.7 to 8.9) among normal versus obese more than or equal to 50 year olds.

While firefighters cannot avoid aging, physicians should counsel firefighters with weight-maintenance or weight-loss advice to prevent and manage elevated ASCVD risk.

To test the feasibility, acceptability, and potential effectiveness of engineering and behavioral interventions to improve the sleep, health, and well-being of team truck drivers (dyads) who sleep in moving semi-trucks.

Drivers (n = 16) were exposed to Condition A a new innerspring mattress, and Condition B a novel therapeutic mattress. A subsample of drivers (n = 8) were also exposed to Condition C use of their preferred mattress (all chose to keep B), switching to an active suspension driver's seat, and completing a behavioral sleep-health program. Primary outcomes were sleep duration, sleep quality, and fatigue. Behavioral program targets included physical activity and sleep hygiene.

Self-reported sleep and fatigue improved with mattress A, and improved further with mattress B which altered vibration exposures and was universally preferred and kept by all drivers. Condition C improved additional targets and produced larger effect sizes for most outcomes.

Results support these interventions as promising for advancing team truck drivers' sleep, health, and well-being.

To assess whether standardized screening and service navigation improve access to primary care in low wage workers.

Four rapid plan-do-study-act cycles were conducted over an 8-week period. Each cycle consisted of four core interventions. Data were collected every 2 to 3 days, then analyzed on run charts and aggregate data tables.

Effective care was achieved by increasing the percentage of patients with a primary care provider from 52% to 79%. Patients' perception of health increased from 3.6 to 4.4 and team communication and support score increased from 3.9 to 4.2 on a 5-point Likert scale.

Patient engagement and a standardized referral process aids in the establishment of routine, effective care. Application of "smart phrases" in electronic health records provides sustainability for use in other occupational medicine practices.

To address which body composition (BC) measures best correlate with cardiorespiratory fitness (CRF) in firefighters and develop a model for accurate CRF estimation compared with traditional methods.

Career firefighters had body mass index (BMI) and waist circumference (WC) measured in addition to body fat percentage (FM%) by dual-energy x-ray absorptiometry (DXA). CRF as maximum oxygen uptake (VO2max) was estimated by rowing machine and measured by indirect calorimetry in a treadmill exercise test.

Fifty two firefighters participated (92.3% men). Univariate correlations with BMI were best with WC. Univariate correlations with VO2max were best with FM%. Obesity classifications by BC measures agreed weakly at best. Multivariate analysis of several variables yielded an improved VO2max estimate (R2 = 0.70).

Fire departments may benefit from more sophisticated measures of BC and CRF to evaluate firefighter fitness.

Describe workplace vaping, prevalence of observed use, attitudes, and perceptions among US adults.

Employees of companies with more than 150 employees, drawn from an opt-in national online panel (N = 1607), ages 18 to 65, completed an online survey in November 2019.

Majority (61.6%) observed coworkers vaping at work and 19.1% reported vaping at work themselves. Participants perceived workplace vaping as moderately harmful (M = 1.9 out of 3), 63.2% were bothered by workplace vaping and 52.1% thought it decreased workplace productivity among non-users. Multiple regression models found workplace vaping prevalence varied by industry and participant characteristics, and attitudes about it varied by tobacco use status.

Workplace vaping and vaping exposure is common in US workplaces. Employees, particularly non-users, hold generally negative perceptions of workplace vaping. Comprehensive policies to prevent workplace vaping are needed to protect workers.

Ventilation and perfusion single-photon emission computed tomography combined with computed tomography (SPECT/CT) is a powerful tool to assess the state of the lungs in chronic obstructive pulmonary disease (COPD). 81mKrypton is a gaseous ventilation tracer and distributes similarly to air, but is not widely available and relatively expensive. 99mTc-Technegas is cheaper and has wider availability, but is an aerosol, which may deposit in hot spots as the severity of COPD increases. read more In this study, 81mKrypton and 99mTc-Technegas were compared quantitatively in patients with severe COPD.

The penetration ratio, the heterogeneity index (with and without band filtering for relevant clinical sizes) and hot spot appearance were assessed in eleven patients with severe COPD that underwent simultaneous dual-isotope ventilation SPECT/CT with both 99mTc-Technegas and 81mKrypton.

Significant differences were found in the penetration ratio for the medium energy general purpose (MEGP) collimators, but not for the low energy general purpose (LEGP) collimators.
