Associations between urinary 3-indoxyl sulfate, a gut microbiome-derived biomarker, and patient outcomes after intensive care unit admission

Highlights: (1) The normal gut microbiome is disrupted in patients who are critically ill. (2) 3-indoxyl sulfate is a gut bacteria byproduct that is excreted in the urine. (3) Evaluate urine 3-indoxyl sulfate as a gut-specific biomarker in the ICU population.

Relationship of the Esophageal Microbiome and Tissue Gene Expression and Links to the Oral Microbiome: A Randomized Clinical Trial

The oral and esophageal microbiomes are closely related within individuals, and esophageal microbiome alterations correlate with tissue gene expression changes.

Colonizing multidrug-resistant bacteria and the longitudinal evolution of the intestinal microbiome after liver transplantation

In a large prospective cohort of liver transplantation (LT) recipients, we identify associations between colonization by multidrug-resistant bacteria (MDRB) and microbiome dysbiosis pre- and post-LT, suggesting colonizing MDRB as an important target for microbiome-informed therapeutic approaches post-LT.

Transfusional iron overload and intravenous iron infusions modify the mouse gut microbiota similarly to dietary iron

Clinical interventions affecting iron status may alter biologically relevant microbial metabolites in the murine gut microbiome.

Gut and Oral Microbiome in Immuno-compromised Hosts

My postdoctoral research explored the dynamics between colonizing and infectious MDRO and commensal bacteria within the gut and oral microbiome. One main focus has been the study of the oral and gut microbiomes and mycobiomes in immunocompromised hosts, primarily liver transplant recipients and people living with HIV. Through 16S rRNA, ITS, and metagenomic sequencing, we linked clinically relevant patient outcomes with changes in the gut or oral micro- and myco-bial structure and diversity.
