Associations between hardiness, C-reactive protein, and telomere length among former prisoners of war

Temperament and sex as moderating factors of the effects of exposure to maternal depression on telomere length in early childhood

Individual differences in sensitivity to context are posited to emerge early in development and to influence the effects of environmental exposures on a range of developmental outcomes. The goal of the current study was to examine the hypothesis that temperament characteristics and biological sex confer differential vulnerability to the effects of exposure to maternal depression on telomere length in early childhood. Telomere length has emerged as a potentially important biomarker of current and future health, with possible mechanistic involvement in the onset of various disease states. Participants comprised a community sample of children followed from infancy to age 3 years. Relative telomere length was assessed from DNA in saliva samples collected at infancy, 2 years, and 3 years. Maternal depressive symptoms and the child temperament traits of negative affectivity, surgency/extraversion, and regulation/effortful control were assessed via maternal report at each timepoint. Analyses revealed a 3-way interaction among surgency/extraversion, sex, and maternal depressive symptoms, such that higher surgency/extraversion was associated with shorter telomere length specifically among males exposed to elevated maternal depressive symptoms. These findings suggest that temperament and sex influence children's susceptibility to the effects of maternal depression on telomere dynamics in early life.

Emotional intelligence, cortisol and α-amylase response to highly stressful hyper-realistic surgical simulation of a mass casualty event scenario

Lifetime exposure to stress leads to risk of suffering from cumulative detrimental physiological and psychological ailments. Due to the nature of healthcare and exposure to trauma, medical professionals are particularly susceptible to the negative impacts of high stress environments. emotional intelligence plays a role in ameliorating the risk of being negatively impacted by these stressors. As such, there is special interest to develop and implement training interventions for medical personnel that would allow them to improve emotional intelligence potential with the goal of enabling them to handle stress better and mitigate burnout. A hyper-realistic surgical simulation training session, replicating the intensity of a Mass-Casualty Event scenario, was implemented to allow medical professionals to experience this in real time. Overall, the training led to increased emotional intelligence, correlating with decreased hypothalamus-pituitary-adrenal axis and sympathetic nervous system stress biomarkers, cortisol and α-amylase. This novel training provides, at least, short-term improvements in emotional intelligence that is reflected with a physiological response. These results guide the ongoing effort to develop therapeutic tools to improve long term stress management, mitigate burnout and reduce post-traumatic stress risk after an exposure to a Mass-Casualty event scenario.

•

This study examines the relationship between emotional intelligence and stress response.

•

Higher values in self-perception and stress management correlate with lower cortisol and α-amylase values.

•

Alpha-amylase is more predictive of pre-event emotional intelligence while cortisol levels are better for post-event.

•

Training improves short-term emotional intelligence, that may be useful to enhance stress management and mitigate burnout.

•

Monitoring α-amylase and cortisol levels may help identify individuals at risk or with lower resilience potential.
