As the aging population undergoes more surgical procedures, understanding the multifactorial risks associated with POCD is increasingly critical. While factors such as age, education level, and preexisting cognitive conditions are established risks, the role of biological sex in POCD remains underexplored. Emerging evidence highlights distinct sex differences in brain morphology, hormonal regulation, and neuroinflammatory responses, which may alter susceptibility to POCD. For instance, estrogen has been shown to exert neuroprotective effects under stress, and women may present greater vulnerability to inflammation-driven brain atrophy. Additionally, male carriers of the APOE4 allele exhibit worse postoperative cognitive outcomes, while female carriers appear relatively protected. This review aims to explore the interaction between biological sex and neuroinflammatory processes in the development of POCD. By delving into these mechanisms, the review seeks to shed light on sex-based disparities in POCD incidence and progression, offering new insights into its pathogenesis. Understanding these differences is vital for developing targeted prevention and treatment strategies, ultimately improving outcomes for both male and female patients while alleviating the strain on healthcare systems.</div></div>","PeriodicalId":20836,"journal":{"name":"Psychoneuroendocrinology","volume":"179 ","pages":"Article 107524"},"PeriodicalIF":3.4,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study also examined whether rumination-cortisol associations differed by rumination type and gender/sex: stressor-focused rumination, which involves dwelling on past or current stressors, and brooding rumination, which focuses on evaluative reactions to sad emotions. The sample included 116 college-aged adults (63 women, 53 men) who provided six salivary cortisol samples throughout the day over five days. Analyses revealed that men and women differed in their associations between stressor-focused rumination and diurnal cortisol. Women with higher levels of stressor-focused rumination displayed flatter diurnal cortisol slopes, whereas the opposite pattern was observed in men.

Higher pre-pandemic PA was associated with reduced odds of depression (<em>OR</em> = 0.964, 95 % <em>CI</em> [0.948; 0.981]) and anxiety (<em>OR</em> = 0.976, 95 % <em>CI</em> [0.953; 1.000]), whereas elevated CRP was associated with 1.343 times higher odds of depression (95 % <em>CI</em> [1.100; 1.641]). PA did not attenuate the inflammation-depression association.</div></div><div><h3>Conclusions</h3><div>The findings suggest that PA may contribute to psychological resilience against stressful life events among older adults but does not appear to mitigate the adverse effects of systemic inflammation on mental health. Further research is needed to explore the psychobiological pathways underlying this protective mechanism.</div></div>","PeriodicalId":20836,"journal":{"name":"Psychoneuroendocrinology","volume":"179 ","pages":"Article 107515"},"PeriodicalIF":3.4,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
