Article Abstract
Introduction: Acute stroke (AS) is a major public health issue globally, exhibiting high morbidity, disability rate, and mortality. Emerging research has demonstrated the critical roles of gut microbiota and its metabolites in pathogenesis, recovery, and prognosis of AS.
Methods: In this study, we investigated alterations in gut microbiota composition and metabolomic profiles in AS patients using 16S rRNA sequencing and untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics technology.
Results: The results revealed significant changes in gut microbiota diversity and community structure in AS patients compared with healthy controls. Notably, the abundance of anti-inflammatory microbiota was increased significantly, accompanied by elevated levels of certain metabolites, such as 6,9,12,15,18,21-tetracosahexaenoic acid and bufadienolide, while levels of urobilin and andrenid acid were significantly reduced. Network analysis further uncovered the significant diferences in microbiota-metabolite interactions between AS patients and healthy controls, indicating gut ecosystem disruption and functional dysfunction in AS.
Discussion: This study sheds light on the mechanisms of brain-gut axis in AS, suggesting potential microbial and metabolite biomarkers, thus providing valuable insights into AS prediction and treatment.

Background: This study aims to analyze research trends and emerging insights into gut microbiota studies from 2015 to 2024 through bibliometric analysis techniques. By examining bibliographic data from the Web of Science (WoS) Core Collection, it seeks to identify key research topics, evolving themes, and significant shifts in gut microbiota research. The study employs co-occurrence analysis, principal component analysis (PCA), and burst detection analysis to uncover latent patterns and the development trajectory of this rapidly expanding field.

Background And Aims: While this strategy is frequently used for other biologics, real-world evidence on subcutaneous (SC) vedolizumab (VDZ) dose intensification in inflammatory bowel disease (IBD) is lacking. This study aimed to assess the effectiveness and safety of SC VDZ intensification.
Methods: We conducted a retrospective study in 25 centers including all patients with active ulcerative colitis (UC) or Crohn's disease (CD) (defined by PRO2), and incomplete or loss of response to SC VDZ 108mg EOW when the drug was intensified.
The contribution of the brain-gut-microbiome axis to intergenerational abnormalities in a rat model of perioperative neurocognitive disorder.

Background: The brain-gut-microbiome (BGM) axis is a communication network through which the brain and gastrointestinal microbiota interact via neural, hormonal, immune, and gene expression mechanisms. Gut microbiota dysbiosis is thought to contribute to neurocognitive disorders, including perioperative neurocognitive disorder (PND), and to various metabolic abnormalities. Recently, we reported that sevoflurane induces neurocognitive deficits in exposed rats as well as their future offspring, with male offspring being particularly affected (intergenerational PND).

Purpose Of Review: This review aims to characterize the known cardiovascular (CV) manifestations associated with inflammatory bowel disease (IBD) and the underlying mechanisms driving these associations.
Recent Findings: Gut dysbiosis, a hallmark of patients with IBD, can result in both local and systemic inflammation, thereby potentially increasing the risk of cardiovascular disease (CVD) in the IBD population. Micronutrient deficiencies, anemia, and sarcopenia independently increase the risk of CVD and are frequent comorbidities of patients with IBD.
