Article Abstract
The association of gut microbiota with lymph node tuberculosis (LNTB) remains unexplored. This study employed metagenomic sequencing and plasma metabolomics analyses to investigate the role of gut microbiota in LNTB patients. Significant alterations in gut microbial diversity were observed in LNTB patients, characterized by a notable reduction in bacterial taxa involved in short-chain fatty acid (SCFA) synthesis, including , , , and , compared to healthy individuals. KEGG pathway analysis further revealed that gut dysbiosis could negatively impact SCFA biosynthesis and metabolism. Plasma metabolomics demonstrated disruptions in metabolites associated with SCFA synthesis and inflammation pathways in the LNTB group. Integrated analysis indicated significant correlations between specific gut microbiota (, , , , , ) and plasma metabolites, including α-benzylbutyric acid, acetic acid, and succinic acid. Our findings demonstrate that gut microbiota dysbiosis and related metabolic dysfunction significantly reduce SCFA production in LNTB patients, potentially identifying novel therapeutic targets for LNTB management.

Background: Several clinical studies have demonstrated that Helicobacter pylori (Hp) infection may exacerbate the progression of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD); however, the underlying mechanisms remain unclear. This study aims to investigate the characterization of the gastric microbiome and metabolome in relation to the progression of MASLD induced by Hp infection.
Methods: We established a high-fat diet (HFD) obese mouse model, both with and without Hp infection, to compare alterations in serum and liver metabolic phenotypes.

This review article describes recent research advances in the relationship between spinal cord injury (SCI) and the gut microbiota and each other's inflammatory response. SCI is a serious neurological disease that directly damages physiological function. Recent studies have shown that SCI significantly affected the composition and function of the gut microbiota, and even caused intestinal inflammation.

Background: Emerging evidence suggests that the gut microbiota (GM) may influence the progression of breast cancer by modulating immune responses. Given the vast diversity of GM and immune cell phenotypes, this study aimed to utilize the most advanced and comprehensive data to explore the causal relationships among the GM, immune cell phenotypes, and survival rates in hormone receptor-positive (HR+) breast cancer patients under different treatment regimens.
Methods: We investigated the causal relationships between the GM, immune cell phenotypes, and survival rates in HR+ breast cancer patients treated with 11 distinct therapeutic strategies using Mendelian randomization.

Clostridioides difficile infection (CDI) remains a significant cause of infectious colitis in the United States. Susceptibility to CDI is associated with perturbation of the gut microbiota, the indigenous microbes in the gastrointestinal tract. Upon colonization, the production of toxins and the ability to produce spores for environmental dissemination contribute to C difficile pathogenicity.

Essential oils (EOs) are a promising alternative to conventional pesticides, but some challenges like high volatility, poor water solubility, and rapid degradation limit their use in Integrated Pest Management (IPM). To overcome these limitations, this study aimed to develop garlic, eucalyptus, and clove EO-based nano-emulsions (EO-NEs) in a bait treatment format through the high-pressure microfluidization technique and investigated the biological activities against Ceratitis capitata. In addition, the adverse effects of the most promising nano-emulsion were evaluated towards a non-target parasitoid Anagaspis daci.
