Studying 1,157 mother-infant pairs of the CHILD Cohort, researchers unravel a possible link between vitamin D supplementation during early-life and protection against C. difficile infection. Vit-D supplementation was also observed to be associated with a lower level of a specific bacterium Megamonas. Megamonas has been shown to be involved in asthma and respiratory viral infections, suggesting other potential benefits for vitamin D such as lowering the risk of viral infections in life. This study is leading the field to new investigations.

In this clinical review, Dr. Matenchuk, Dr. Mandhane and Dr. Kozyrskyj gathered recent discoveries about the relationship between sleep, circadian rhythm and the gut microbiome. Building on the work of Krueger and Opp, 2016 and Broussard et al., 2016, the authors consolidate the current literature on this relationship
