TL;DR: In this paper, a systematic review and meta-analysis was conducted to investigate the associations between endogenous concentrations of sex hormones and colorectal cancer risk, and no associations were found for endogenous sex steroid hormones in men or post-menopausal women with CRC risk.

TL;DR: The Greek government has announced plans to introduce a smoke-free law for cigarettes and tobacco products in the country, aimed at reducing the risk of secondhand smoke and promoting healthy smoking.

TL;DR: Time-varying Cox regressions showed T2D patients with stroke, peripheral vascular disease, atrial fibrillation, heart failure or hypertension were at higher risk of dementia compared to those without such comorbidities, and a range of cardiovascular and non-cardiovascular comorbbidities were associated with further increases of dementia risk in T1D patients.

TL;DR: This work presents a method to find feature correspondence between two similar LC–MS metabolomics experiments or batches using only the features’ RT, m/z, and FI, and demonstrates the method on both real and synthetic datasets, using six orthogonal validation strategies.

TL;DR: In this paper, the authors used a competing risks approach and carefully grounded that within a causal inference emulated trial framework to identify candidate biomarkers of metformin's actions in the brain that might mediate reduced dementia risk.
