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.

Probiotics in reducing obesity by reconfiguring the gut microbiota.

Obesity, as a global health crisis, is increasingly linked to intestinal microecology. Probiotics colonise the body, effectively regulating the balance of intestinal flora, while strengthening the intestinal barrier, activating the immune response, releasing beneficial substances, and maintaining micro-ecological balance. This process not only enhances the defence against pathogens, but also reduces the production of inflammatory factors and lowers the level of chronic inflammation.

Childhood obesity and central precocious puberty.

Central precocious puberty (CPP) is an endocrine disorder in children caused by the early activation of the hypothalamic-pituitary-gonadal axis (HPGA), leading to elevated gonadotropin-releasing hormone (GnRH), which triggers the development of gonads and the secretion of sex hormones. This eventually results in the development of internal and external genitalia and secondary sexual characteristics. CPP significantly affects the physical and mental health of children and may increase the risk of various adult diseases.

Background And Hypothesis: For the rapidly growing population of older people living with schizophrenia (PLWS), psychological resilience, or the capacity to adapt to adversity, is an understudied target for improving health. Little is known about resilience and its longitudinal impact on outcomes among PLWS. This study assesses trajectories of resilience-related traits in PLWS and a nonpsychiatric comparison group (NCs) and longitudinal interactions between resilience and health.

Alzheimers Dement

Background: Growth/differentiation factor-15 (GDF15) has been associated with dementia risk, yet its predictive value across cohorts and sub-population, as well as its relationship with endophenotypes relevant to dementia, remains unknown.

Methods: Using the Atherosclerosis Risk in Communities (ARIC) study as the discovery cohort, we examined the relationship between plasma GDF15 levels (SomaScan) and risk for incident all-cause dementia (ACD) in late-life (N=4,287, 7-year follow-up, M=75±5) and in midlife (N=11,595, 20-year follow-up, M=57±6). Utilizing the UK Biobank (UKB; replication cohort), we related plasma GDF15 (Olink) to incident ACD (N=35,673, 14-year follow-up, M=61±5), vascular dementia (VaD) and Alzheimer's disease dementia (AD).
