Circulating glycine levels have been associated with reduced risk of coronary artery disease (CAD) in humans but these associations have not been observed in all studies. We evaluated whether the relationship between glycine levels and atherosclerosis was causal using genetic analyses in humans and feeding studies in mice. Serum glycine levels were evaluated for association with risk of CAD in the UK Biobank.

This study characterizes dMMR rectal cancer patients, comparing response after neoadjuvant radiotherapy and oncological outcomes to mismatch repair proficient (pMMR) rectal cancer patients.
Method: A retrospective cross-sectional cohort study was conducted in 67 Dutch centers.
Article Synopsis
- The study investigates how gut microbial metabolites (GMM), specifically phenylacetylglutamine (PAGln), are linked to cardiovascular diseases (CVD) in people with alcohol use disorder.
- In experiments with mice, researchers found that chronic alcohol consumption led to changes in gut microbes and increased PAGln levels, which were associated with cardiovascular issues.
- PAGln was shown to cause heart and blood vessel problems independent of alcohol, indicating that it plays a significant role in the development of CVD related to alcohol consumption.
The Duke activity status index (DASI), a self-administered 12-item questionnaire has been used to estimate functional capacity and recently demonstrated prognostic information. We aimed to develop an abbreviated version for clinical applications. Leveraging the Cleveland Clinic GeneBank Study, we developed an abbreviated DASI questionnaire (aDASI) with the machine learning XGBoost algorithm, with the goal of maintaining the accuracy and reliability of the original DASI.
