Alterations in Oral and Gut Microbiota with Enhanced Oral-Gut Interaction in Cognitive Impairment Following Stroke
Overview
{'text': 'This study identifies significant alterations in oral and gut microbiota associated with post-stroke cognitive impairment (PSCI). Findings reveal a coordinated dysbiosis characterized by reduced commensals and increased opportunistic taxa, suggesting a potential link between oral-gut interactions and cognitive outcomes.', 'action': "Clarify 'coordinated dysbiosis'."}
Background
{'text': 'Post-stroke cognitive impairment (PSCI) is a prevalent condition that adversely affects recovery and quality of life. Understanding the role of microbiota in PSCI is crucial, as gut dysbiosis has been implicated in cognitive decline. This study expands the focus to include oral microbiota, highlighting its potential impact on cognitive health following stroke.', 'action': 'Include examples of gut dysbiosis effects.'}

Key Findings
{'text': '
PSCI participants exhibited reduced oral richness and gut diversity.
Depletion of oral commensals (e.g., Leptotrichia, Neisseria) and enrichment of opportunistic taxa (e.g., Pseudomonas, Streptococcus).
Increased presence of Gram-negative potential pathogens in the gut microbiota.
Predicted functional alterations in the gut related to lipopolysaccharide biosynthesis and tryptophan metabolism.
Stronger oral-gut association indicated by lower dissimilarity and higher shared-genera fraction in PSCI.
Combined oral-gut features demonstrated high exploratory performance in distinguishing PSCI.

Clinical Implications
{'text': 'The findings suggest that monitoring oral and gut microbiota may provide insights into cognitive outcomes in post-stroke patients. Clinicians should consider the potential role of oral health in managing PSCI and explore interventions targeting microbiota as a therapeutic strategy.', 'action': 'Suggest specific microbiota interventions.'}
Conclusion
{'text': 'This study underscores the importance of the oral-gut microbiota axis in PSCI, revealing significant dysbiosis that may influence cognitive impairment. Further research is needed to validate these findings and explore their clinical applications.', 'action': 'Emphasize need for clinical trials.'}
