Randomized Controlled Trial
Gut, microbiota-dependent trimethylamine-N-oxide is associated with long-term all-cause mortality in patients with exacerbated chronic obstructive pulmonary disease.
The gut, microflora-dependent metabolite trimethylamine-N-oxide (TMAO) has emerged as a dietary-associated risk factor for incident cardiovascular events. Chronic obstructive pulmonary disease (COPD) is a prevalent disease worldwide with a high associated risk for cardiovascular disease and death due to an infectious cause. ⋯ Increased circulating TMAO levels per se were associated with long-term all-cause mortality in patients with COPD independent of type of exacerbation. However, this association was largely explained by comorbidities and age. Whether TMAO levels can additionally be influenced by nutritional interventions should be addressed in future studies.

Randomized Controlled Trial
Maternal methyl donor supplementation during gestation counteracts bisphenol A-induced oxidative stress in sows and offspring.
Maternal oxidative stress is harmful for embryonic, fetal, and placental development. The aim of this study was to investigate whether methyl donor supplementation during gestation effectively ameliorates maternal and placenta oxidative stress up to offspring. ⋯ BPA diets fed to sows during gestation aggravated oxidative stress status in sows and piglets, whereas the methyl donor diets enhanced antioxidant capacity of sows and piglets and ameliorated oxidative stress induced by BPA.
