Dr. Stephen J.D. O’Keefe is a Professor of Medicine at the University of Pittsburgh and a practicing gastroenterologist at the University of Pittsburgh Medical Center. His work focuses on ‘nutritional gastroenterology’ — in particular, translational research that evaluates physiological and pathophysiological responses to dietary intake.
Dr. O’Keefe gave a talk at Experimental Biology 2015 called, “Diet, Microbiota, and Microbial Metabolites in Rural Africans and African Americans“, where he presented data from his recent study.

Scientists have discovered a fungus that delays wound healing in mice and is enriched in inflamed tissue from patients with Crohn’s disease. The findings, coupled with the discovery of an engineered yeast that suppresses inflammation in a mouse model of colitis, highlights the potential of studying fungi-host interactions in IBD.
Restoring maternal microbes immediately after birth, in a practice dubbed ‘vaginal seeding’, has been suggested as a means of improving microbiome development in cesarean-born neonates. Two new studies come to contradictory findings, however, highlighting the need for more clinical trials before the practice is generalized.
While we have known for a while that a diet consisting of fiber-rich foods reduces the risk of developing chronic diseases and lowers people’s mortality rate, scientists have only recently started elucidating why fiber is beneficial for human health. This article clarifies the definition and health implications of the closely related terms fiber, MACs and prebiotics.
