Filter by:This is a prospective study with three specific aims: (1) To convene a consensus conference to develop a guideline for antibiotic use in infants (age < 3 yrs) with suspected ventilator-associated infection; (2) To evaluate outcomes before and after implementation of the antibiotic guideline; (3) To evaluate changes in the tracheal microbiome over the course of mechanical ventilation
Our trial try to eradicate digestive tract colonization of patient harboring Extreme Drug Resistant (XDR) bacteria by performing a fecal transplantation.
The composition of gastric microbiota is determined by the status of Helicobacter pylori infection. In subjects who have never been infected by H. pylori, gastric microbiota includes various bacteria, creating ideal microbial diversity. This ideal microbial diversity is destroyed by H. pylori infection at low intragastric pH. Since it is difficult for most bacteria to proliferate within an acidic stomach, relative H. pylori abundance gives rise to microbial dysbiosis. Conversely, unideal microbial diversity is often observed in infected individuals with impaired gastric secretory ability at hypochlorhydric condition. Bacteria producing carcinogenic N-nitrosamine compounds are often detected in individuals with past or chronic H. pylori infection at high intragastric pH. Nonetheless, microbial imbalance that occurs in the earlier phase before gastric carcinognenesis is uncertain.
