Alzheimer's disease (AD) diagnosis relies on clinical symptoms complemented with biological biomarkers, the Amyloid Tau Neurodegeneration (ATN) framework. Small non-coding RNA (sncRNA) in blood have emerged as potential predictors of AD. We identified sncRNA signatures specific to ATN and AD, evaluated both their contribution improving AD conversion prediction beyond alone.
Abstract Background Coexisting long-term conditions (LTCs) in psoriasis and their potential causal associations with the disease are not well established. Objectives To determine distinct clusters of LTCs people bidirectional association between these psoriasis. Methods Using latent class analysis, cross-sectional data from UK Biobank were analysed to identify psoriasis-related comorbidity profiles. Linkage disequilibrium score regression (LDSR) was applied compute genetic correlation LTCs....
Excessive adiposity increases disease risk, yet the exact underlying mechanisms remain unknown. We compared sex-specific metabolic signatures (MSs) of indices (non-allometric: body fat %, waist circumference, hip waist-to-hip ratio, mass index; allometric: a shape index, waist-to-hip-index ratio) and examined their associations with 29 clinical biomarkers in 151,526 UK Biobank participants. MSs performance was validated an independent cohort. In females, mainly consisted lipoprotein particle...
Abstract Background Waist circumference (WC) and its allometric counterpart, “a body shape index” (ABSI), are risk factors for colorectal cancer (CRC); however, it is uncertain whether associations with these measurements limited to specific molecular subtypes of the disease. Methods Data from 2,772 CRC cases 3,521 controls were pooled four cohort studies within Genetics Epidemiology Colorectal Cancer Consortium. Four markers (BRAF mutation, KRAS CpG island methylator phenotype,...

Background Sleep traits may influence cancer risk; however, their associations with prostate (PCa), endometrial (ECa), and epithelial ovarian (EOCa) remain unclear. Methods We conducted an observational analysis using the UK Biobank cohort a two sample Mendelian randomisation (MR) to investigate association of six sleep such as duration, chronotype, insomnia, daytime napping, sleepiness, snoring PCa, ECa, EOCa risk. Cox proportional hazards models were used for analysis, while inverse...
