Background: The causal relationship between PM (particulate matter with an aerodynamic diameter ≤2.5 μm) and common mental disorders, along with its neuropathological mechanisms, remains unclear.
Methods: We used genome-wide association study datasets from the UK Biobank and Psychiatric Genomics Consortium to systematically investigate the causal relationship between PM and nine common psychiatric disorders using two-sample Mendelian randomization (TSMR) methods.
The combined effect of cardiovascular risk factors on breast cancer in women is unknown. The relationship between genetic risk combined with cardiovascular health (CVH) levels and breast cancer has not been confirmed. This study aims to explore the relationship between CVH level based on life's essential 8 (LE8) score and breast cancer risk in women with different menopausal statuses and to estimate further the effect of CVH level combined with genetic susceptibility on breast cancer risk.
