Background: Both genetic and dietary factors play significant roles in the etiology of colorectal cancer (CRC). To evaluate the relationship between certain food exposures and the risk of CRC, we carried out a large-scale association analysis in the UK Biobank.
Methods: The associations of 139 foods and nutrients' intake with CRC risk were assessed among 118,210 participants. A polygenic risk score (PRS) of CRC was created to explore any interaction between dietary factors and genetic susceptibility in CRC risk. The hazard ratio (HR) and 95% confidence interval (CI) of CRC risk linked to dietary variables and PRS were estimated using Cox regression models. Multiple comparisons were corrected using the error discovery rate (FDR).
Results: During a mean follow-up of 12.8 years, 1466 incidents of CRC were identified. In the UK Biobank, alcohol and white bread were associated with increased CRC risk, and their HRs were 1.08 (95% CI: 1.03-1.14; FDRP = 0.028) and 1.10 (95% CI: 1.05-1.16; FDRP = 0.003), whereas dietary fiber, calcium, magnesium, phosphorus, and manganese intakes were inversely associated. We found no evidence of any PRS-nutrient interaction relationship in relation to CRC risk.
Conclusions: Our results show that higher intakes of alcohol and white bread are associated with increased CRC risk, whilst dietary fiber, calcium, magnesium, phosphorus, and manganese are inversely associated.

Background: Current evidence suggests higher physical activity (PA) levels are associated with a reduced risk of colorectal cancer (CRC). However, the mediating role of the circulating metabolome in this relationship remains unclear.
Methods: Targeted metabolomics data from 6,055 participants in the EPIC cohort were used to identify metabolites associated with PA and derive a metabolomic signature of PA levels.

Objectives: To assess strategies for optimizing participation of underserved minorities in a blood-based early CRC detection test study (PREEMPT CRC; NCT04369053) at a hospital serving primarily Black patients.
Methods: Culturally sensitive, racially congruent research staff approached patients undergoing average-risk screening colonoscopy. Consent/study procedures were synchronized with clinical appointments.

Since 1987, King Chulalongkorn Memorial Hospital (KCMH) has performed a substantial number of heart transplants as a specific therapy for advanced-stage heart failure. This descriptive study aimed to analyze post-transplant survival in the recent era compared to earlier periods and examine the pharmacogenetics of related immunosuppressants. Data from all recipients who underwent heart transplants from 1987 to 2021 were retrospectively retrieved from the electronic medical record.

Background: DNA hypomethylation and uracil misincorporation into DNA, both of which have a very important correlation with colorectal carcinogenesis. Folate plays a crucial role in DNA synthesis, acting as a coenzyme in one-carbon metabolism, which involves the synthesis of purines, pyrimidines, and methyl groups. MTHFR, a key enzyme in folate metabolism, has been widely studied in relation to neural tube defects and hypertension, but its role in colorectal cancer remains underexplored.

Background: Genome-wide association studies (GWAS) have identified susceptibility loci for colorectal cancer (CRC), but the underlying mechanisms remain unclear. This study investigates functional genetic variants in promoter regions of Leucine Rich Repeat Containing 6 (LRRC6) at 8q24 and Myotubularin Related Protein 10 (MTMR10) at 15q13.3 and their association with CRC susceptibility.
