Salivary cortisol/DHEA ratio response to acute academic stress and its association with performance in middle-to-late adolescents.

Objectives: Neuroendocrine coupling across adolescent transition conditions a stage of heightened variability in hypothalamic-pituitary-adrenal axis stress reactivity, likely impacting the adaptive physiological response to psychological stressors during adolescence. This study aimed to assess the salivary cortisol, DHEA, and cortisol/DHEA ratio variation in response to acute academic stress and its association with academic performance.

Methods: A longitudinal observational study with a combined event- and time-based protocol was conducted.

The socioeconomic gradient in overweight and obesity among Colombian adult and pediatric populations: A scoping review.

The imminent increase in overweight and obesity prevalence constitutes a pervasive concern for the adult and pediatric Colombian population. Nonetheless, the unequal distribution across distinct social groups limits the implementation of public health policies targeting these escalating rates. This study aimed to compile existing evidence regarding the prevalence of overweight and obesity in relation to the socioeconomic status (SES) of the Colombian population.

Cerebrospinal fluid levels of hypothalamic-pituitary-adrenal axis hormones in MCI and dementia due to Alzheimer's disease: a systematic review.

Unlabelled: Underlying the neuropsychological manifestations of Alzheimer's disease (AD), hypothalamic-pituitary-adrenal (HPA) axis dysregulation and subsequent hypercortisolemia have been proposed as major mechanisms driving AD progression from mild cognitive impairment (MCI) to the onset of dementia. Nonetheless, changes in cerebrospinal fluid (CSF) levels of HPA axis hormones remain controversial despite their potential in AD diagnosis and prognosis testing.

Objective: This study aimed to review the evidence of the variation in CSF levels of CRH, ACTH, and cortisol in subjects with mild cognitive impairment (MCI) and AD compared with subjects without cognitive disorders.
