AI Article Synopsis
- The study explores the link between hair cortisol concentration (HCC) as a marker for chronic stress and the risk of coronary arterial disease (CAD) among 24 participants.
- Results indicate that while HCC is significantly associated with CAD, its impact is weak compared to established risk factors like dyslipidemia and age.
- Psychological and physiological resilience measures were considered, but they did not show a significant independent association with CAD, suggesting HCC's contribution to CAD risk is minimal in a typical population.
Article Abstract
The widespread prevalence of cardiovascular disease underscores the continuing need for identifying modifiable risk factors and novel targets for therapeutic intervention. Hair cortisol concentration (HCC) is a promising biomarker for evaluating the contribution of chronic stress to the pathogenesis and prognosis of coronary arterial disease (CAD). In this cross-sectional study of 24 participants, we assessed the risk of CAD associated with HCC and with perceived chronic stress (Perceived Stress Score), controlling for the established risk factors of age, diabetes, hypertension, dyslipidemia, and obesity. In fully adjusted Poisson regression models, we additionally evaluated CAD risk with the simultaneous inclusion of psychological and physiologic resilience measures (CD-RISC, DHEA-S). Our results show that HCC, but not PSS, is significantly associated with CAD (incident rate ratio 0.99, confidence interval 0.98-1.00, p = 0.01), but the magnitude of the association is weak and inverse, and less than with dyslipidemia and age. The association remained significant after inclusion of the sum of resilience measures via a combined resiliency score. Resilience was not independently significantly associated with CAD. Our findings indicate the contribution of HCC to CAD risk is small in an average-risk population and remains after adjustment for multisystem resilience.

Grazing is usually associated with higher well-being in dairy cows. However, current research on the welfare of grazing cows lacks validation via blood profiling. We monitored four dairy farms that seasonally graze in the temperate North American Pacific Northwest, USA, to address this gap.

In intensive beef production systems, social dominance relationships among cattle and human-cattle relationships constantly affect cattle welfare. However, these factors have not been investigated to assess their long-term effects on cattle welfare. In this study, the relations of hair cortisol concentrations of group-housed pregnant cows with their social rank and avoidance distance when approached by humans were analysed.

Background: After the birth of a child, also fathers may develop postpartum depression. Altered steroid hormone concentrations are discussed as a possible underlying mechanism, as these have been associated with depressive symptoms in previous studies outside the postpartum period. While higher paternal testosterone levels have been found to protect against paternal postpartum depressive symptoms (PPDS), an association between higher cortisol levels and PPDS has been seen in postpartum mothers, with no comparable studies available on fathers.

Background: Maternal stress can have short and long term adverse (mental) health effects for the mother and her child. Previous evidence suggests that the gut microbiota may be a potential mediator and moderator for the effects of stress via various pathways. This study explored the maternal microbiota trajectory during pregnancy as well as the association between pre- and postnatal maternal stress and features of the maternal and infant gut microbiota during and after pregnancy.

Introduction: Cardiovascular diseases (CVDs) present differently in women and men, influenced by host-microbiome interactions. The roles of sex hormones in CVD outcomes and gut microbiome in modifying these effects are poorly understood. The XCVD study examines gut microbiome mediation of sex hormone effects on CVD risk markers by observing transgender participants undergoing gender-affirming hormone therapy (GAHT), with findings expected to extrapolate to cisgender populations.
