Summary: This review examines the interaction between bile acid metabolites and intestinal inflammation in inflammatory bowel disease (IBD), highlighting their role in regulation of the inflammatory milieu through pathways such as autophagy, apoptosis, and the inflammasome pathway. The study also discusses the potential of novel experimental and bioinformatics approaches to further advance our understanding of the role of bile acids in IBD and inform therapeutic strategies.

Summary: Patients with pouchitis exhibit significant alterations in microbial species, metabolic pathways, and enzyme functions, with specific enrichment of Ruminococcus gnavus strains and depletion in pathways related to butyrate and secondary bile acid synthesis. Microbial feature-based classifiers have been developed to distinguish between patients with a normal pouch and pouchitis, identifying predictive species and genes for pouchitis. The study highlights potential microbial targets for intervention to attenuate small intestinal inflammation in pouchitis and CD.

Summary: This study aimed to develop a core outcome set for real-world studies in adult patients with inflammatory bowel disease (IBD). Candidate outcomes and outcome measures were identified through a systematic review and a modified Delphi consensus process. The international panel agreed on the final core outcome set, which will facilitate the synthesis and generation of real-world evidence.

Summary: This study investigated the association between gut microbiota, bile acids, and colorectal cancer in IBD patients. The results found that specific bacterial taxa were associated with cancer, while bile acids were not. Additionally, clustering analysis identified microbiota clusters associated with clinical features.

Summary: This study investigated the ameliorative effects of berberine on gut microbiota dysbiosis and flora metabolites in a UC rodent model. The results showed that berberine improved the pathological phenotype, attenuated intestinal barrier disruption, and mitigated colonic inflammation. It also alleviated gut microbiota dysbiosis and ameliorated the bile acid imbalance induced by DSS. Furthermore, berberine treatment repaired gut barrier damage and activated the FXR and TGR5 signal pathway.

Summary: The SPIRIT consensus group has agreed that the ultimate therapeutic goal in both CD and UC is to prevent disease impact on patients' lives, including health-related quality of life, disability, and fecal incontinence, as well as prevent complications in the short and long term, such as bowel damage, surgeries, disease extension, extraintestinal manifestations, and dysplasia or cancer. These recommendations will need to be validated in clinical studies before being implemented in disease-modification trials.

Summary: The study systematically identified ultrasound scoring indices for assessing inflammatory bowel disease activity, with common components including bowel wall thickness, colour Doppler imaging, and bowel wall stratification. The correlation between ultrasound indices and reference standards, as well as sensitivity, specificity, accuracy, and other properties, varied within certain ranges. However, reliability and responsiveness data were limited, and most studies were rated with unclear or high risk of bias.

Summary: This review discusses the differential regulation of miRNAs in inflammatory bowel disease (IBD) and their potential diagnostic and therapeutic applications. Through literature curation and computational analysis, a consensus set of differentially expressed miRNAs in mucosal tissues was obtained. The role of these miRNAs and their potential targets in IBD are highlighted.

Summary: Hepatocyte growth and proliferation depend on membrane phospholipid biosynthesis, which is significantly influenced by short-chain fatty acids (SCFAs) generated through bacterial fermentation. Antibiotic treatment and dysbiosis not only affect gut microbiota, but also impair hepatic lipid synthesis and liver regeneration.

Summary: Wilson disease is a rare inherited metabolic disorder with diverse clinical presentations affecting the liver, neurological system, psychiatric status, and vision, often in combination. Mutations in the ATP7B gene lead to copper accumulation in hepatocytes and/or neurons, making clinical diagnosis challenging. Diagnosis is complicated by mild and non-specific manifestations, mutations with unclear effects on protein function, and ambiguous laboratory tests, particularly concerning serum ceruloplasmin levels. Establishing a global collaboration of researchers, clinicians, and patient advocacy groups is crucial for identifying and addressing the outstanding challenges of Wilson disease.

Summary: This study demonstrates that deficiency of Trib1 promotes the formation of atherosclerotic lesions and increases plasma cholesterol and triglyceride levels in Ldlr(-/-) mice. It also suggests that Trib1 deficiency alters hepatic lipid metabolism and induces inflammation.

Summary: Visceral adiposity is associated with liver steatosis and the development of NASH. Mice lacking SNTB2 have reduced intra-abdominal fat mass and do not accumulate hepatic cholesteryl esters on a MCD diet. However, they still develop a similar NASH pathology as wild type mice, suggesting a minor role of intra-abdominal fat and liver cholesteryl esters in this model.

Summary: Reliability, robustness, and interlaboratory comparability of quantitative measurements in clinical lipidomics studies are crucial. The different ex vivo stability of lipids in blood poses a risk to data interpretation. Clear recommendations for blood sample collection are necessary. In this study, we used UHPLC-high resolution mass spectrometry to investigate the stability of 417 lipid species in EDTA whole blood under different temperature conditions and time points. Our data suggest that cooling whole blood immediately and continuously, and separating plasma within 4 hours, unless focusing on robust lipids, are recommended. Lists of lipids' ex vivo (in)stability and potential biomarkers in whole blood are provided. Overall, our results contribute to the international efforts in achieving reliable and comparable clinical lipidomics studies in the future.

Summary: Mice lacking FGF receptors 1 and 2 (Fgfr1 and Fgfr2) in hepatocytes are hypersensitive to cytotoxic injury during liver regeneration, which is associated with the protective role of the urinary-reproductive factor Uhrf2 in liver cells. Uhrf2 expression increases during regeneration after partial hepatectomy in an FGFR-dependent manner, but the abundance of Uhrf2 in liver cells is lower in FGFR-deficient mice. Hepatocyte-specific knockout of Uhrf2 leads to liver necrosis, impaired hepatocyte proliferation, and liver failure.

Summary: This study demonstrates the therapeutic potential of the FGFR inhibitor infigratinib in preventing and suppressing the first clinical episodes of MOG(35-55)-induced experimental autoimmune encephalomyelitis, reducing inflammation and neurodegeneration. Infigratinib also promotes oligodendrocyte maturation and remyelination, and decreases neurodegeneration-associated lipids. Therefore, infigratinib holds promise as a treatment for multiple sclerosis.

Summary: The levels of lysophosphatidylcholine (LPC) are elevated in the synovial fluid of patients with osteoarthritis (OA). Different LPC species have varying effects on the regulation of proteins and phospholipids in fibroblast-like synoviocytes (FLSs). IL-1 & beta; has the most significant impact on the regulation of proteins by LPC 16:0, suggesting its potential role in modulating inflammatory and catabolic mechanisms.

Summary: Using fatty acid methyl ester gas chromatography-mass spectrometry, this study found that both saturated and unsaturated fatty acids increase in the bone marrow. Characteristic fatty acid patterns were identified in patients with normal BMD, osteopenia, and osteoporosis, and different patterns were found in plasma, red bone marrow, and yellow bone marrow. Specific fatty acids correlated with osteoclast activity and suggested a possible mechanism for how fatty acids interfere with BMD, but no single fatty acid in the profile could be claimed for controlling BMD.

Summary: G-protein-coupled receptors OGR1 and TDAG8 play opposite roles in inflammatory bowel disease, with OGR1 deficiency reducing inflammation severity and TDAG8 deficiency increasing inflammation. These findings suggest the potential importance of OGR1 and TDAG8 as therapeutic targets.
