Background Alcohol use disorder (AUD) is a psychiatric that widespread worldwide. significant contributor to the global burden of death, disability and disease. Modulation gut microbiota promising approach improve efficacy minimize adverse effects colorectal cancer treatment. The relationship between presence microbes AUD has been widely validated. However, few studies have examined this using bibliometric methods. Therefore, study analyzes research hotspots trends in human microbiology over last two decades from perspective. This aims at provide new directions for basic clinical field. Objective A comprehensive discussion current state intestinal flora. Methods We collected publications Web Science Core Collection database 2003 2023 according established inclusion criteria. analyzed countries, institutions, authors, contributions CiteSpace, VOSviewer, Scimago Graphics visualize Results total 2,102 were obtained, with rapid increase number since 2016. United States China are major contributors field network partners several countries. Five hundred ninety-five academic journals published articles on topic. author highest Prof. Bernd Schnabl Department Gastroenterology University California, San Diego. In addition “gut flora” “AUD,” high frequency words keyword co-occurrence analysis included alcoholic liver disease, tryptophan metabolism, enterohepatic axis, fecal microbial transplantation. Conclusion results visualization key areas past 20 years. suggest role its potential mechanisms, especially therapeutic targets, should be closely monitored could become hot topic

Background. There is a lack of studies focusing on the combined impact metformin, empagliflozin, and levothyroxine gut microbiota in patients with type 2 diabetes mellitus (T2DM) hypothyroidism. The purpose study was to examine how combination metformin empagliflozin affects composition Materials methods. We enrolled 47 who have been receiving hormone replacement therapy at stable dose over past years were newly diagnosed T2DM. All participants divided into two groups received either alone or plus for 6 months. Metabolic hormonal parameters measured before after treatment, stool samples analyzed using PCR sequencing. Results. found that both groups, there an improvement carbohydrate metabolism, lipid profile, liver transaminases treatment. group treated had more significant reduction glucose, glycated hemoglobin, atherogenicity coefficient than alone. also resulted lower levels Firmicutes increase number Actinobacteria, as well higher ratio Bacteroides fragilis Faecalibacterium prausnitzii. Conclusions. shows first time can directly affect T2DM These changes may be necessary treating this cohort require further investigation.

ABSTRACT Medical modulation of sex hormone levels is a cornerstone treatment for many conditions that impact well-being, including cancer, fertility/infertility, gender dysphoria, and chronic metabolic diseases such as diabetes obesity. The microbial residents the intestine, known microbiota, interact with hormones in there correlative evidence this interaction bidirectional. Based on these published findings, we hypothesized transgender individuals receiving exogenous testosterone part their gender-affirming medical might undergo changes intestinal microbiome. To test this, collected 26 stool samples from nine before up to 8 months after initiation subjected metagenomic analysis. While no species were significantly associated duration therapy, pathways generate glutamate increased abundance, while those consume decreased. Glutamate precursor arginine, increase arginine its metabolites plasma. We hypothesize increases uptake by enterocytes, thus decreasing access microbiota amino acid. pilot study establishes therapy microbiome, more comprehensive necessary establish testosterone-driven shifts metatranscriptome, metabolome, plasma metabolome. IMPORTANCE human intestine inhabited large community microbes Members microbiome diet along host. Thus, metabolomes host microbe are intricately linked. Testosterone alters In particular, positively correlated. investigate analyzed metagenomes treatment. project, found modest structure but an abundance spare consumption. propose uses amount available
