Summary: Elevated social fear in infancy is associated with later social maladjustment and psychopathology. This study found that increased hair cortisol concentration (HCC) in infants was related to increased distress vocalizations during a Stranger Approach task, while steeper diurnal cortisol slope was associated with fewer distress vocalizations. Economic strain did not affect the relationship between cortisol measures and social fear responses.

Summary: This study aimed to explore the associations between maternal perceived stress and salivary cortisol levels during pregnancy with cortisol levels in early infancy, and to identify early life factors associated with infants' cortisol levels. The results showed that maternal stress and salivary cortisol levels were not associated with infants' cortisol levels, while birth weight, maternal marital status, and infant feeding may influence cortisol levels.

Summary: Stress hormones have an impact on the processing of fear, anxiety, and related memory mechanisms. Recent laboratory findings highlight the timing-dependent effects of stress on extinction learning and retrieval. This has implications for clinical intervention approaches, such as exposure therapy, and the administration of stress hormone cortisol.

Summary: This study suggests that the dysregulated function of the hypothalamic-pituitary-adrenal (HPA) axis might play a role in the relationship between adverse childhood experiences (ACEs) and depression, especially in individuals exposed to multiple ACEs. Lower cortisol levels in early adolescence were found to mediate the association between ACEs and elevated depressive symptoms in early adulthood, independent of genetic factors.

Summary: This study explored morning cortisol levels and stress responses in psychopathic offenders, non-psychopathic offenders, and non-offender controls. The researchers found that psychopathic offenders exhibited significantly lower cortisol levels during a stress task compared to controls, while non-psychopathic offenders showed a similar but non-significant trend. However, there were no significant differences in cortisol response slopes among the three groups.

Summary: This study evaluated a panel of antioxidant and oxidant biomarkers in the saliva of calves during a stressful period of weaning and grouping, finding significant increases in concentrations 4 days after grouping. Additionally, cortisol and oxytocin concentrations were found to be significantly correlated with the biomarkers of oxidative status. This suggests that a balance between antioxidants and oxidants is maintained during stressful situations in calves.

Summary: The study found a positive correlation between diurnal salivary cortisol and hair cortisol concentration in children. Additionally, an increase in effortful control scores was associated with a higher likelihood of having high hair cortisol levels, although this association slightly weakened after adjustments. No clear associations were found between temperament dimensions and stress-related biomarkers.

Summary: Understanding the impact of stress on fear learning is valuable for understanding stress-related disorders. This study found that stress impaired the acquisition of fear, particularly in individuals with greater cortisol responses. However, stress did not significantly influence the generalization of fear. These findings suggest that stress alters fear acquisition via cortisol-related mechanisms and may help explain the alteration of fear memories in stress-related disorders.

Summary: The study found that reading augmented reality (AR) books can reduce salivary cortisol levels to a certain extent in hospitalized pediatric patients, but the decrease is not significant. Compared to reading a standard children's book, AR books can improve the VAS score for psychological stress.

Summary: Early life stress can lead to psychiatric illnesses, with the hippocampus playing a crucial role. Stress in the pre-pubertal period impairs adult hippocampal neurogenesis and related behaviors in rodent models. Environmental enrichment during adolescence can reverse the effects of early stress on hippocampal function.

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: In the pig industry, there is a growing concern about animal welfare, which has led to the exploration of technologies such as epigenetic biomarkers to predict animal welfare on farms. This review discusses the studies conducted in this area, highlights the benefits of investing in research to enhance animal welfare and consumers' trust, and suggests the potential use of epi-biomarkers for animal welfare certification.

Summary: Background: Aggression in pigs is a welfare concern in the pig industry; Objective: To understand the changes in affiliative behaviors in pigs after mixing and their relationship to aggression; Results: Affiliative behaviors remained stable after mixing, with nosing decreasing and play and non-agonistic contact increasing; Affiliative behaviors were negatively related to aggression at mixing, but nosing and play behaviors were positively related to aggression in the following weeks; Conclusion: Promoting non-agonistic contact and other positive social behaviors may help reduce aggression among pigs.

Summary: The study found that an acute health challenge on the estrus day alters CL gene expression, particularly with significant downregulation of angiogenic genes VEGF and FTL1 among animals challenged with LPS, and upregulation of the HSD3B1 gene. Furthermore, differences in housing systems also resulted in variations in the expression of STAR and LHCGR genes.

Summary: There should be discussion about the function and effects of stereotypies in relation to the time during which they are shown. Studies show that variation in the timeline of expression of stereotypies can lead to different outcomes in animal welfare, with stereotypic behavior in the prenatal period potentially affecting the phenotype of offspring.

Summary: This study demonstrates that lameness in pregnant sows can lead to decreased placental efficiency in inactivating stress hormones, potentially impacting the welfare of the offspring. Therefore, greater attention should be paid to the lameness of sows as it may affect the welfare of both the sow and her offspring.

Summary: This study analyzes the perceptions of precision livestock farming (PLF) technology held by stakeholders in the US swine industry using the Q-methodology approach. By following up with stakeholders interviewed 6 months earlier, the study found three distinct viewpoints: PLF improves farm management, animal welfare, and labor conditions; PLF does not solve industry problems; PLF has limitations and could lead to data ownership conflicts. Stakeholders with in-depth knowledge of PLF were optimistic about its potential, while those with basic understanding were skeptical. However, all stakeholders agreed on the importance of training and adoption of PLF. The study's results hold promise for informed decision-making about PLF implementation in the US swine industry.
