    Exploring the use of thermal infrared imaging in human stress research. by Veronika Engert, Arcangelo Merla, Joshua A Grant, Daniela Cardone, Anita Tusche, Tania Singer

    Published 2014-01-01
    “…While correlations between the thermal imprints and established stress markers were mostly non-significant, the thermal imprints (but not the established stress makers) did correlate with stress-induced mood changes. Multivariate pattern analysis revealed that in contrast to the established stress markers the thermal imprints could not disambiguate anticipation, stress and recovery phases of both tests. …”

    Published 2025-04-01
    “…Results: A total of 1,585 participants were prospectively included (mean age 67.7 ± 11.6 years, 63.3 % male); 148 (9.3 %) patients presented a moderate-to-severe ischemia. In multivariate analysis, the odds of moderate-to-severe ischemia was increased, with adjusted odds-ratio (ORa) of 1.39 [95 % confidence interval (95 % CI): 1.07–1.80; p = 0.013], 1.33 (95 % CI: 1.01–1.75; p = 0.042), and 1.22 (95 % CI: 0.96–1.57; p = 0.10) for each increase of one Interquartile Range (IQR) in PM2.5, PM10 and NO2 exposure, respectively (IQR equal to 3.3, 4.3 and 10.0 µg/m3, respectively). …”
