Association between dietary tea consumption and non-alcoholic fatty liver disease: a study based on Mendelian randomisation and National Health and Nutrition Examination Survey (2005-2018) association between tea and non-alcoholic fatty liver disease.

Tea can improve the progression of some metabolic diseases through anti-inflammatory and antioxidant effects, but its impact on non-alcoholic fatty liver disease (NAFLD) is still controversial. The aim of this paper is to identify the relationship between tea and NAFLD by Mendelian randomisation (MR) and complete clinical validation using National Health and Nutrition Examination Survey (NHANES) database. MR used data from Genome Wide Association Study, with inverse-variance weighted (IVW) as principal analytical methods.

Endoscopic retrograde cholangiopancreatography using a pediatric colonoscope in patients with Roux‑en‑Y gastrectomy and an intact major duodenal papilla.

Associations of vitamin D status with colorectal cancer risk and survival.

Biological evidence suggests that vitamin D has numerous anticancer functions, but the associations between vitamin D status and colorectal cancer (CRC) risk and survival remain inconclusive. Based on UK Biobank, we prospectively evaluated the associations of season-standardized 25-hydroxyvitamin D (25(OH)D) concentrations with CRC risk among 360 061 participants, and with survival among 2509 CRC cases. We observed an inverse linear relationship between 25(OH)D concentrations and CRC risk (P for linearity = .
