Early Head Start Services Improve Infants’ Cortisol Regulation and Recovery
Improving Infants’ Stress-Induced Cortisol Regulation through Attachment-Based Intervention: A Randomized Controlled Trial Author: Berlin LJ, et al. (2019), Psychoneuroendocrinology. ABSTRACT Attachment-based parenting interventions have shown positive effects on early cortisol regulation, a key biomarker. Evaluations to date have focused on diurnal cortisol production in high-risk infants. It is important to understand whether attachment-based intervention may […]
Salivary DHEA-Cortisol Ratio Associations with Parental Maltreatment and Juvenile Incarcerated Male Psychopathy
Dehydroepiandrosterone (DHEA) and its ratio to cortisol moderate associations between maltreatment and psychopathology in male juvenile offenders Author: Kimonis ER, et al. (2019), Psychoneuroendocrinology. ABSTRACT This study examined whether DHEA and its ratio to cortisol moderated risk for psychopathology among incarcerated youth exposed to childhood maltreatment. Resistance to stress-related psychopathology under adversity was also examined in […]
Cortisol as a Target Mediator for Therapeutic Horseback Riding Effects in Youth with Autism Spectrum Disorder
Replication Pilot Trial of Therapeutic Horseback Riding and Cortisol Collection With Children on the Autism Spectrum Author: Zhaoxing P, et al. (2019), Frontiers. ABSTRACT We aimed to determine whether results of our prior randomized control trial [RCT; NCT02301195, (1)] of Therapeutic Horseback Riding (THR) for children and adolescents with autism spectrum disorder (ASD) could be replicated […]
Low Salivary Alpha-Amylase Awakening Response Associated with Reduced Professional Efficacy
Reduced professional efficacy is associated with a blunted salivary alpha-amylase awakening response. Author: Landolt K, et al. (2018), Physiol Behav. ABSTRACT: The job demands-resources model (JD-R) has shown an ability to predict worker engagement and exhaustion, yet to our knowledge, research has not been conducted that assesses the JD-R model with physiological indicators of chronic stress […]
Salivary Cotinine Suggests Infants from Low-Income Families have a Higher Smoke Exposure Risk
Magnitude and Chronicity of Environmental Smoke Exposure Across Infancy and Early Childhood in a Sample of Low-Income Children. Author: Gatzke-Kopp LM, et al. (2018), Nicotine Tob Res. INTRODUCTION: Infants and young children may be at an increased risk for second- and thirdhand exposure to tobacco smoke because of increased respiration rate and exposure to surface residue. […]
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 Stress Biomarkers as Tools for Determining Stress Adaptability and Resilience
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Authors: Hellewell SC & Cernak I (2018), J Trauma Stress. ABSTRACT: Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas others […]
HPA Axis Attunement May Serve a Bonding Function within Women’s Close Friendships
The Role of Co-Rumination and Adrenocortical Attunement in Young Women’s Close Friendships. Author: Rankin A, et al. (2018), Psychoneuroendocrinology. ABSTRACT: Attunement, or synchrony, of behavior and physiology has been well documented in family, mother-child, and romantic relationships. This study aimed to determine whether attunement of the hypothalamic-pituitary-adrenal (HPA) axis occurs in women’s close friendships, and […]
Salivary Uric Acid May be an Important Biomarker Indexing Health and Disease Risk
The validity, stability, and utility of measuring uric acid in saliva. Author: Riis JL, et al. (2018), Biomarkers in Medicine SUMMARY: Uric acid (UA) is associated with cardiovascular and metabolic disorders, as well as a wide range of other health conditions and behaviors. A noninvasive measure of UA would be particularly useful in biobehavioral health […]
Salivary Secretory Immunoglobulin A: The impact of smoke exposure during and after pregnancy
Prenatal and postnatal cigarette and cannabis exposure: Effects on Secretory Immunoglobulin A in early childhood. Author: Molnar DS, et al. (2018), Neurotoxicol Teratol. BACKGRUOND: AIMS: Secretory Immunoglobulin A (SIgA) plays a critical role in immune functioning by preventing pathogens from adhering to epithelial mucosa. Most infectious agents enter the body via mucosal surfaces, thus SIgA […]
Influence of Adverse Childhood experiences on stress regulation in BPD
Attachment – Related Regulatory Processes Moderate the Impact of Adverse Childhood Experiences on Stress Reaction in Borderline Personality Disorder. Author: Ehrenthal JC, et al (2018), Journal of Personality Disorders BACKGROUND: In this study, the authors explored whether attachment insecurity moderates the effects of adverse childhood experiences on stress reactivity in the context of borderline personality […]
Association of salivary adiponectin with serum and inflammatory markers
Adiponectin: Serum-Saliva Associations and Relations with Oral and Systemic Markers of Inflammation Author: Riis JN, et al. (2017), Peptides This study addresses gaps in our understanding about the validity and utility of using salivary adiponectin to index serum adiponectin levels. Matched blood and saliva samples were collected on a single occasion from healthy adults (n=99; […]
Measuring salivary transferrin to determine blood contamination levels
A statistical method to calculate blood contamination in the measurement of salivary hormones in healthy women. Author: Behr GA, et al. (2016), Clinical Biochemistry OBJECTIVES: Previous studies have reported that salivary concentrations of certain hormones correlate with their respective serum levels. However, most of these studies did not control for potential blood contamination in saliva. […]
