Background: In recent years, the relationship between gut microbiota and human health has garnered significant attention. Notably, the potential connection between gut microbiota and mental health issues, such as depression and anxiety, has emerged as a new focal point for research. While some studies suggest a possible link between these factors, the field remains in its early stages of development, and there are notable methodological and sample size limitations.
Purpose: This study aims to systematically summarize the knowledge systems, research hotspots, and development trends related to intestinal microflora within the context of depression research.
Methods: This study conducted a search for publications related to intestinal microflora and depression in the Web of Science Core Collection (WOSCC) prior to August 6, 2024. The selected literature was subsequently analyzed using VOSviewer (v.1.6.20), SCImago Graphica (v.1.0.39), and CiteSpace (v.6.3.1).
Results: The study encompassed a total of 1,046 publications, demonstrating a consistent increase in annual publication volume. The primary research countries identified are China and the United States, with notable contributions from institutions such as the University of California and University College Cork, among others. Keywords analysis highlighted high-frequency terms including "gut microbiota," "depression," and "anxiety," and revealed 10 keyword clusters along with 20 strongest citation bursts keywords. The focus of research has shifted from compositional analysis of gut microbiota to its role in the pathogenesis of depression.
Conclusions: Research on gut microbiota and depression is growing, but there is still a need for greater collaboration between authors and institutions across regions, more ongoing interaction and communication to further explore the mechanisms of action of gut microbiota, to develop microbiota-based interventions, and to facilitate translation of research findings into clinical practice.

Background: This study aimed to comprehensively characterize the gut microbiome and identify individual and grouped gut microbes associated with food allergy (FA) using 16S rRNA gene sequencing.
Methods: Fecal samples were collected from children with IgE-mediated FA and from sex- and age-matched controls. The V3-V4 variable regions of the 16S rRNA gene of the gut microbiome were profiled using next-generation sequencing (Illumina, USA).

Background: Clostridium innocuum is a vancomycin-resistant pathobiome associated with poor clinical outcomes in inflammatory bowel disease (IBD). In ulcerative colitis (UC), it correlates with reduced remission rates, while in Crohn's disease (CD), it is linked to creeping fat formation and intestinal strictures. Notably, some patients experience refractory or recurrent C.

Mucosal healing is the mainstream goal of modern treat-to-target strategy as it is associated with a significantly more favorable disease course in IBD patients with either ulcerative colitis or Crohn's disease. Recent advances in endoscopic imaging technologies have overcome the traditional concept of mucosal healing assessed with conventional white light imaging, allowing for multiple levels of endoscopic healing up to the boundaries of molecular and functional evaluation. In this review, we focused on conventional and emerging strategies to assess endoscopic healing in ulcerative colitis and ileocolonic Crohn's disease, examining their pros and cons in real life practice.

This review provides an in-depth exploration of the evolving role of immunotherapy in gastrointestinal (GI) cancers, with a particular focus on immune checkpoint inhibitors (ICIs) and their associated predictive biomarkers. We present a detailed analysis of established biomarkers, such as PD-L1, microsatellite instability (MSI), tumor mutational burden (TMB), and the tumor microenvironment (TME), as well as emerging biomarkers, including gut microbiota and Epstein-Barr virus (EBV). The predictive value of these biomarkers in guiding clinical decision-making and optimizing immunotherapy outcomes is thoroughly discussed.

Background: Many factors are associated with the development and progression of liver fat and fibrosis; however, genetics and the gut microbiota are representative factors. Moreover, recent studies have indicated a link between host genes and the gut microbiota. This study investigated the effect of patatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 (C > G), which has been reported to be most involved in the onset and progression of fatty liver, on liver fat and fibrosis in a cohort study related to gut microbiota in a non-fatty liver population.
