Salivary Cortisol and Alpha-Amylase Connection in Mother-Infant Interactions
Ecologically salient stressors and supports and the coordination of cortisol and salivary alpha-amylase in mothers and infants. Author: Hibel LC, et al. (2018), Physiology and Behavior. ABSTRACT: This study examines the integration of the two main branches of the stress response system: the autonomic nervous system (via salivary alpha-amylase, sAA) and the hypothalamic-pituitary-adrenal axis (via cortisol). Mothers (n = 117) were […]
Salivary alpha-amylase response to pain in children with cancer
Emotion regulation and positive affect in the context of salivary alpha-amylase response to pain in children with cancer Author: Jenkins BN, et al (2017), Pediatric Blood & Cancer BACKGROUND: Children with cancer routinely undergo painful medical procedures invoking strong physiological stress responses. Resilience to this pain may be conferred through resources such as emotion regulation […]
Salivary bioscience supports pre-clinical evaluation of new medical device
Preclinical evaluation of the effect of the combined use of the Ethicon Securestrap® Open Absorbable Strap Fixation Device and Ethicon Physiomesh™ Open Flexible Composite Mesh Device on surgeon stress during ventral hernia repair. Author: Sutton N, et al. (2017), Dove Press Aim: To evaluate whether performing ventral hernia repairs using the Ethicon Physiomesh™ Open Flexible […]
Traumatic childhood injuries related to changes in stress reactivity
Altered Stress System Reactivity After Pediatric Injury: Relation with Post-Traumatic Stress Symptoms Author: Ewing-Cobbs, et al. (2017), Psychoneuroendocrinology Research Article Highlights; HPA and ANS stress systems were dysregulated after nonintentional pediatric injury. HPA and ANS activity and regulation varied with age at injury and type of injury. Cortisol reactivity to social stress was attenuated after […]
Childhood maltreatment affects cortisol and alpha-amylase stress reactivity
Patterns of cortisol and alpha-amylase reactivity to psychosocial stress in maltreated women Author: Mielock AS, et al. (2017), Journal of Affective Disorders BACKGROUND: Childhood maltreatment can trigger enduring changes in major stress response systems, particularly in the context of major depressive disorder (MDD). However, the relative impact of maltreatment versus MDD on hypothalamic-pituitary-adrenal axis and […]
Adolescent appraisal of interparental conflict is reflected by stress reactivity
Adolescent conflict appraisals moderate the link between marital conflict and physiological stress reactivity Author: Lucas-Thompson RG, et al. (2017), Journal of Research on Adolescence The goal of this study was to advance understanding of how adolescent conflict appraisals contribute uniquely, and in combination with interparental conflict behavior, to individual differences in adolescent physiological reactivity. Saliva […]
Variation in salivary cortisol and alpha-amylase rhythms over 24 months
Long-term stability of diurnal salivary cortisol and alpha-amylase secretion patterns Author: Skoluda N, et al. (2017), Physiology & Behavio This study aimed to investigate long-term stability and variability of diurnal cortisol and alpha-amylase patterns. Diurnal cortisol and alpha-amylase secretion patterns were assessed on a single workday with three waves of measurement across a total time […]
Temperament predicts salivary cortisol and alpha-amylase in BASE jumpers
Stress reactivity and personality in extreme sport athletes: The psychobiology of BASE jumpers Author: Monasterio E, et al. (2016), Physiology & Behavior This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict […]
The stress response to perceived discrimination as indicated by salivary measures
Perceived Discrimination, Racial Identity, and Multisystem Stress Response to Social Evaluative Threat among African American Men and Women Author: Lucas T, et al (2016), Psychosomatic Medicine. OBJECTIVES: Understanding individual differences in the psychobiology of the stress response is critical to grasping how psychosocial factors contribute to racial and ethnic health disparities. However, the ways in […]
Chronic caregiver-related stress linked to diurnal salivary alpha-amylase rhythms
Diurnal Salivary Alpha-Amylase Dynamics Among Dementia Family Caregivers Author: Liu Y, et al (2016), Health Psychology. Objective: The study examined diurnal regulation of salivary alpha-amylase (sAA) in association with daily stressors, adult day services (ADS) use, and other caregiving characteristics. Method: A sample of 165 family caregivers of individuals with dementia (IWD) completed an 8-day […]
Determining the appropriate statistical approach for effective analysis of hormone ratios
How to use and interpret hormone ratios Author: Sollberger S, et al (2016), Psychoneuroendocrinology. Hormone ratios have become increasingly popular throughout the neuroendocrine literature since they offer a straightforward way to simultaneously analyze the effects of two interdependent hormones. However, the analysis of ratios is associated with statistical and interpretational concerns which have not been […]
In utero infant’s stress response system impacted by mother’s psychological & physiological state
Developmental origins of infant stress reactivity profiles: A multi-system approach. Author: Rash JA, et al (2016), Developmental Psychobiology This study tested the hypothesis that maternal physiological and psychological variables during pregnancy discriminate between theoretically informed infant stress reactivity profiles. The sample size included 254 women and their infants. Maternal mood, salivary cortisol, respiratory sinus arrhythmia […]
Sympathetic and hypothalamic-pituitary-adrenal asymmetry in generalized anxiety disorder
Developmental origins of infant stress reactivity profiles: A multi-system approach. Author: Reeves JW, et al (2016), Psychophysiology Physiologic investigations of generalized anxiety disorder (GAD) have skewed toward assessment of the autonomic nervous system, largely neglecting hypothalamic-pituitary-adrenal (HPA) axis variables. Although these systems coordinate, suggesting a degree of symmetry, to promote adaptive functioning, most studies opt […]
