Background: Work-related stress is a well-established contributor to mental health decline, particularly in the context of burnout, a state of prolonged exhaustion. Epigenetic clocks, which estimate biological age based on DNA methylation (DNAm) patterns, have been proposed as potential biomarkers of chronic stress and its impact on biological aging and health. However, their role in mediating the relationship between work-related stress, physiological stress markers, and burnout remains unclear.

Background And Objective: While current clinical guidelines generally advocate for beta-blocker therapy following acute myocardial infarction (AMI), conflicting findings have surfaced through large-scale observational studies and meta-analyses. We conducted this systematic review and meta-analysis of published observational studies to quantify the long-term therapeutic impact of beta-blocker across heterogeneous AMI populations.
Methods: We conducted comprehensive searches of the PubMed, Embase, Cochrane, and Web of Science databases for articles published from 2000 to 2025 that examine the link between beta-blocker therapy and clinical outcomes (last search update: March 1, 2025).

Incubation temperature affects both growth and energy metabolism in birds after hatching. Changes in cellular mechanisms, including mitochondrial function, are a likely but unexplored explanation for these effects. To test whether temperature-dependent changes to mitochondria may link embryonic development to the post-natal phenotype, we incubated Japanese quail eggs at constant low (36.

The onset of puberty is increasingly observed at earlier ages in children, especially in girls with obesity, a trend that predisposes them to long-term metabolic and reproductive disorders in adulthood. Bile acids have emerged as pivotal signaling molecules in both metabolic and reproductive disorders, but remain unexplored in the early onset of puberty in children. Herein, we find elevated levels of muricholic acid (MCA) species in the serum of girls with central precocious puberty, which strongly correlate with indices of hypothalamic-pituitary-gonadal axis activation and can reach peak levels during puberty among healthy children.

Objective: Although existing evidence suggests a potential link between dementia and adverse outcomes in patients with COVID-19, a definitive relationship is uncertain. This study aimed to evaluate the impact of dementia on in-hospital outcomes of patients in the presence of COVID-19.
Methods: The US Nationwide Inpatient Sample (NIS) was searched for patients 65 years or older hospitalised for COVID-19 in 2020.
