Lack of biodiversity in the gut or elevated metabolites associated with heart failure severity

Some people who experience heart failure have less biodiversity in their gut or have elevated gut metabolites, both of which are associated with more hospital visits and greater risk of death, according to a systematic review of research findings led by Georgetown University School of Nursing & Health Study researchers and colleagues.

Co-development of three systems linked with baby's respiratory health

A new multidisciplinary study conducted by researchers at the University of Rochester Medical Center has found that the co-development of three systems, the gut microbiome, respiratory system and immune system, is correlated with a baby's respiratory health, and an infant can have negative respiratory outcomes if the development of one of these systems is disrupted.
