Some of the bacteria, termed microbiota, support viability and functions of host cells directly by generating beneficial short-chain fatty acid components of dietary fibers and other metabolites of host compounds including secondary bile acids and indole derivatives of tryptophan. Short-chain fatty acids also recruit immune protective elements exemplified by IL-22, which has beneficial effects on intestinal epithelium by their IL-22 receptors. Other bacteria have detrimental effects on host cells through lipopolysaccharides and diverse toxins. An increased ratio of detrimental to beneficial microbiomal bacteria, a state termed dysbiosis, is observed in human diseases of many systems. Therapies for dysbiosis involve largely dietary manipulation and more recently fecal microbiota transplantation. Resistant and recurrent Clostridium difficile diarrhea responds dramatically to fecal microbiota transplantation, but this approach requires additional evaluation in other diseases. The potential prognostic value of microbiome characteristics suggests future uses in precision medicine.</p>","PeriodicalId":50807,"journal":{"name":"American Journal of Medicine","volume":" ","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to care delays, authorization requirements were associated with disease exacerbation, preventable hospitalization, prolonged hospital stay, and lower rates of disease-free survival. Studies spanned multiple specialties including oncology, cardiology, behavioral health and pediatrics.
