A Cross-Sectional Study of Salivary and Gut Microbiomes in Hemodialysis Patients with Heart Failure, Non-Heart Failure Patients, and Healthy Controls

The objective is to uncover the specific impact of heart failure on the salivary and gut microbiomes of dialysis patients, to further elucidate the intricate mechanisms of interaction between these two microbial communities, and ultimately, to provide a robust theoretical basis for the future development of microbiome-based biomarkers or therapeutic strategies.
