The hidden burden of college life: Stress, sleep, and salivary biomarkers in students—A cross-sectional study

university students face substantial psychological pressures, and stress-related mental health disorders are recognized as major public health concerns. While biomarkers such as cortisol have been extensively studied, integrated analyses of neuroendocrine-immune-circadian interactions remain limited. In this cross-sectional study with two complementary components, psychometric assessments of 637 undergraduates revealed that 90.4% experienced moderate-to-high perceived stress. These stress levels correlated with fatigue (r = 0.41, p p p < 0.001). These findings indicate that salivary biomarker profiles are associated with perceived stress.

Mental Hum’s note

A study found that high perceived stress in university students was linked to changes in salivary biomarkers, but its cross-sectional design limits understanding of cause and effect.

The anxiolytic effect of dexmedetomidine in adult perioperative patients: a systematic review with meta-analysis of randomized controlled trials

Perioperative anxiety in adults is common and impairs postoperative recovery. The use of dexmedetomidine during perioperative procedures is increasing, but evidence on its effects on anxiety-related outcomes remains to be systematically synthesized.This systematic review was based on searches of PubMed, Embase, Web of Science, MEDLINE, and the Cochrane Library from database inception through May 4, 2026. Eligible studies were randomized controlled trials evaluating perioperative dexmedetomidine in adults and reporting quantitative anxiety outcomes.Twelve RCTs involving 1,373 participants were included. Overall anxiety scores were lower with dexmedetomidine than with control (SMD = −0.
