Summary: Errors in deadly police force are met with demands for explanations and have led to multidisciplinary research. Stressful occupational conditions affect police performance and exposure to traumatic encounters may affect mental health and performance. This study found that biological measures may not be specific enough to predict deadly force errors and non-clinical psychological symptoms do not interfere with decision-making.

Summary: This study compared the diurnal patterns of cortisol, amylase, and chromogranin A in saliva. The results showed that cortisol exhibited the least variation among individuals, while chromogranin A showed the highest variation. Factors such as BMI, age, and gender were found to affect the levels of these biomarkers.

Summary: This study aimed to investigate how different baseline states of mind affect the diurnal patterns of salivary stress biomarkers. The results showed that cortisol and alpha-amylase levels were highest on stressful days and lowest on relaxing days, while chromogranin A levels showed the opposite pattern. The study also found that mindfulness practice had different effects on these biomarkers compared to a general relaxed state of mind.

Summary: The study suggests that interactions between students and young donkeys can reduce anxiety levels psychologically, but have no significant impact on the salivary cortisol levels of the donkeys. More research is needed to further understand the benefits of student-donkey interactions.

Summary: This study evaluated the impact of rapid heat stress on the rate of salivary cortisol appearance and found that rapid heat stress leads to an increased rate of salivary cortisol appearance.

Summary: This study found that males and females exhibit different physiological and psychological responses when facing stressors. Males showed significantly higher somatic anxiety post-startle, while females exhibited significantly higher somatic anxiety post-startle and lower self-confidence levels.

Summary: This study aimed to investigate the diurnal variation in salivary progesterone levels during the menstrual cycle among Indian women. A longitudinal study was conducted with a small sample size of 31 fertile Indian women, and it was found that there was a significant diurnal variation in progesterone levels across the menstrual cycle, with higher levels in the morning.

Summary: This study aimed to investigate the neuroendocrine responses based on cortisol, dehydroepiandrosterone (DHEA), cortisol/DHEA ratio, and chromogranin A levels, which reflect the activity of the hypothalamic-pituitary-adrenal axis, according to the presence or absence of psychological stress in patients with gingivitis and periodontitis compared to that in healthy controls. The results showed that salivary cortisol and chromogranin A levels increased with the severity of periodontal disease; their levels were the highest in the periodontitis group and were significantly higher in the following descending order: periodontitis, gingivitis, and healthy control groups. Periodontitis and psychological stress were significant and strong predictors of above-average cortisol levels and cortisol/DHEA ratios.

Summary: Saliva composition has diurnal variations, which are not affected by citric acid stimulation. The variation characteristics of male and female under resting state and acid stimulation are basically the same, with the trend of salivary alpha-amylase activity being opposite to that of cortisol.

Summary: This study investigated the association between HPA-axis function and pain-related outcomes in chronic pain patients, with findings suggesting that CAR and AUCG may influence individual differences in pain perception. Additionally, sex differences were observed among KOA patients, highlighting the potential relationship between morning HPA activation and pain perception.

Summary: Breeding programs for certain horse breeds may require performance tests, which can negatively impact the welfare of horses. Research has shown that age and number of starts in championships do not increase horses' resistance to stress, as participation in competitions can lead to increased cortisol levels.

Summary: Exposure to and perceptions of stress are associated with altered systemic inflammation, with diurnal cortisol slopes playing a role in linking self-reported psychological stress to inflammation. The results support an allostatic load model of psychosomatic health, highlighting the importance of cortisol in understanding the relationship between stress exposure, perceived stress, and immune functioning.

Summary: In this study, a molecularly imprinted polymer (MIP) was used as a detection scaffold for salivary cortisol, a reliable biomarker for psychological disorders, to achieve highly sensitive detection. The MIP, with a three-dimensional recognition network through hydrogen bonds, provided high selectivity and sensitivity. The use of MIP-OFET as a chemical sensor allowed for accurate analysis and quantification of salivary cortisol.

Summary: This study investigated the perceived stress, resilience, and salivary cortisol levels in pharmacy students during exam periods. Results showed that female students had lower resilience and higher cortisol output on exam days, though this difference decreased over the academic year. The study highlighted that students can adapt to stress through modulation of cortisol production over time.

Summary: The experience of everyday minority stressors is uniquely associated with diurnal cortisol levels in LGBT adults, while general stressors only predict cortisol levels 12 hours postwake. This suggests that daily minority stressors may have implications for the mental and physical health of LGBT individuals.
