Article Synopsis
- Colorectal cancer (CRC) is a major health concern, and understanding how genetic and environmental factors interact can help identify at-risk groups.
- This study analyzed data from over 45,000 CRC cases to assess both multiplicative and additive interactions between genetic risk scores and various environmental factors, finding no multiplicative interactions but significant additive ones for high genetic susceptibility individuals.
- Results suggest that individuals with high genetic risk could benefit more from lifestyle interventions like reducing alcohol intake or increasing fruit and fiber consumption, emphasizing the need for targeted prevention strategies in CRC care.
Article Synopsis
- Consumption of fiber, fruits, and vegetables may lower the risk of colorectal cancer (CRC), but genetic factors might influence this connection.
- A large study involving nearly 70,000 participants identified two significant genetic variants linked to dietary intake and CRC risk using advanced statistical methods.
- The findings suggest specific genetic loci (SLC26A3 and NEGR1) may affect how fiber and fruit consumption interacts with CRC risk, highlighting the need for more research on the underlying mechanisms.
Background And Aims: Microscopic colitis (MC) is a common cause of chronic diarrhea; however, the clinical course of this disease is poorly understood. We aimed to investigate how patients diagnosed with MC were treated in routine clinical practice and how their symptoms compared to patients with other causes of chronic diarrhea at one year follow-up.
Methods: We conducted a case-control study of patients undergoing outpatient colonoscopy to evaluate diarrhea.
Genome-wide association studies (GWAS) have identified more than 200 common genetic variants independently associated with colorectal cancer (CRC) risk, but the causal variants and target genes are mostly unknown. We sought to fine-map all known CRC risk loci using GWAS data from 100,204 cases and 154,587 controls of East Asian and European ancestry. Our stepwise conditional analyses revealed 238 independent association signals of CRC risk, each with a set of credible causal variants (CCVs), of which 28 signals had a single CCV.

In this exploratory cross-sectional study, we examine whether vaginal fluid metabolites differ by race among patients with OC, if they are associated with systemic inflammation, and if such associations differ by race. Study participants were recruited from the Ovarian Cancer Epidemiology, Healthcare Access, and Disparities Study between March 2021 and September 2022.
