Late-Night Salivary Cortisol: Cut-Off Definition and Diagnostic Accuracy for Cushing’s Syndrome in a Portuguese Population

Acta Médica Portuguesa, 2019
Introduction: Diagnosis of Cushing’s syndrome remains a challenge in clinical endocrinology. Even though late-night salivary cortisol is used as screening tool, individualized cut-off levels for each population must be defined.

Assessment of exercise-induced stress via automated measurement of salivary cortisol concentrations and the testosterone-to-cortisol ratio: a preliminary study

Scientific Reports, 2023
In this study, our aim was to validate whether the automated measurement of salivary testosterone and cortisol concentrations and the testosterone-to-cortisol (T/C) ratio, considering their individual circadian rhythms can be used to assess the stress ...

Evaluation of stress among dental undergraduates and postgraduates using salivary cortisol as a biomarker

Indian Journal of Dental Research, 2022
Background: Stress is a non-specific response of the body to any demand. Professional education has a certain level of stress inherent in it. Dental students have been reported in the literature to experience more stress than medical students. Objective:

Salivary and Free Serum Cortisol Evaluation [PDF]

Military Medicine, 2010
Physiologic free serum cortisol may more accurately reflect adrenal function than total cortisol levels. Salivary cortisol estimates free serum cortisol. We researched the clinical viability of salivary cortisol in hospitalized patients.Free serum cortisol, and salivary cortisol were measured via ELISA in hospitalized and outpatient patients.We ...

Association Between Hair Cortisol, Sarcopenia, and Sarcopenic Obesity: Results From the ELSA‐Brasil Study

AGING MEDICINE, EarlyView.
This study investigated the association between hair cortisol levels and dynapenia, sarcopenia, and sarcopenic obesity in the ELSA‐Brasil study. Hair cortisol was used as a biomarker of chronic stress. No significant associations were observed between hair cortisol and the outcomes assessed.
