Investigating acute stress and working memory in youth with salivary cortisol and alpha-amylase
February 14, 2022Stress and working memory in children and adolescents: Insights from a multisystem approach Tsai, et al., (2021) Journal of Experimental Child Psychology ABSTRACT: Despite considerable research with adults suggesting that acute stress negatively affects working memory (WM), a core cognitive function, few studies have assessed these effects in youths. Studies that have been conducted have […]

Salimetrics’ Team Supports NIH Funded SARS-CoV-2 Post-Vaccination Study of Women’s Health
December 16, 2021A new study seeks to investigate SARS CoV-2 vaccine effects on menstruation in female adolescents using salivary bioscience with the support of Salimetrics. While the current SARS-CoV-2 vaccines are considered safe and effective at preventing infection and hospitalizations, some women have reported menstrual cycle changes post-vaccination. Although incidents are low, changes in cycle length and […]
Salivary Cortisol and alpha-amylase assayed in ethnic minorities depicts atypical diurnal rhythm
December 2, 2021Stress response asymmetries in African American emerging adults exposed to chronic social adversity Wood, et al., (2021) The International Journal on the Biology of Stress ABSTRACT: Chronic stress is linked to social adversity and underlies many health disparities among ethnic minorities. Cortisol and salivary alpha-amylase (sAA) reflect sensitivity to adversity and are related to health […]
Trier Social Stress Test: Validating a Remote, TSST-Online Protocol
November 16, 2021Validation of an online version of the Trier Social Stress Test in a study of adolescents Gunnar, et al., (2021) Psychoneuroendocrinology ABSTRACT: Introduction: The Trier Social Stress Test (TSST) is the most widely used protocol for activating a stress response of the hypothalamic-pituitary-adrenocortical (HPA) axis and other stress-mediating systems. A number of variants of the […]
Statistical Approaches to Reduce Bias in Left-censored Salivary Data
July 26, 2021Censored Data Considerations and Analytical Approaches for Salivary Bioscience Data Ahmadi, H. et al., (2021) Psychoneuroendorcinology ABSTRACT: Left censoring in salivary bioscience data occurs when salivary analyte determinations fall below the lower limit of an assay’s measurement range. Conventional statistical approaches for addressing censored values (i.e., recoding as missing, substituting or extrapolating values) may introduce […]

Blunted Morning Salivary Cortisol Associated with Cardiovascular Risk
July 19, 2021Blunted circadian cortisol in children is associated with poor cardiovascular health and may reflect circadian misalignment Dai, W. et al., ( 2021) Psychoneuroendocrinology ABSTRACT: Objectives: Circadian cues in children (sunlight, exercise, diet patterns) may be associated with health outcomes. The primary objective was to assess associations of daily cortisol fluctuations (morning, night) with cardiovascular health […]
Salivary cortisol correlates with DNA methylation in preterm infants
July 16, 2021DNA methylation in former extremely low birth weight newborns: association with cardiovascular and endocrine function Padbury, J. et al., (2021) Pediatric Research ABSTRACT: Background: There is increased risk of cardiovascular, metabolic, and hypertensive disorders in later life in the preterm population. We studied school-age children who had been born extremely premature who had undergone endocrine, […]
Salivary SARS-CoV-2 IgG Assay: A practical alternative for screening and monitoring vaccine antibody response and seroprevalence.
June 24, 2021Comparative performance of multiplex salivary and commercially available serologic assays to detect SARS-CoV-2 IgG and neutralization titers Heaney et al., ( 2021) medRxiv ABSTRACT: Oral fluid (hereafter saliva) offers a non-invasive sampling method for the detection of SARS-CoV-2 antibodies. However, data comparing performance of salivary tests against commercially-available serologic and neutralizing antibody (nAb) assays are […]
