Abstract Background: Ten‐day sequential therapy with a proton pump inhibitor (PPI) and amoxicillin followed by PPI, clarithromycin, an imidazole typically achieves Helicobacter pylori eradication rates of 90–94% (Grade B success). Aims: We tested whether prolonging treatment continuing throughout the 14‐day period would produce ≥95% result. Methods: This was multicenter pilot study in which H. ‐infected patients received sequential–concomitant hybrid (esomeprazole for 7 days esomeprazole,...

The gut microbiome and its metabolites are increasingly implicated in several cardiovascular diseases, but their role human myocardial infarction (MI) injury responses have yet to be established. To address this, we examined stool samples from 77 ST-elevation MI (STEMI) patients using 16 S V3-V4 next-generation sequencing, metagenomics machine learning. Our analysis identified an enriched population of butyrate-producing bacteria. These findings were then validated a controlled...
