The burden of irritable bowel syndrome and functional dyspepsia in Poland: a cross-sectional study from West Pomeranian Voivodship.
BMC Gastroenterol
January 2025
Department of Gastroenterology, Pomeranian Medical University in Szczecin, Unii Lubelskiej 1, Szczecin, 71-254, Poland.
Background: Functional gastrointestinal disorders (FGIDs), now known as disorders of gut-brain interaction (DGBIs), such as Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD), significantly impact global health, reducing quality of life and burdening healthcare systems. This study addresses the epidemiological gap in Poland, focusing on the West Pomeranian Voivodeship.
Methods: We conducted a cross-sectional study of 2070 Caucasian patients (58.
The gut-brain axis underlying hepatic encephalopathy in liver cirrhosis.

Up to 50-70% of patients with liver cirrhosis develop hepatic encephalopathy (HE), which is closely related to gut microbiota dysbiosis, with an unclear mechanism. Here, by constructing gut-brain modules to assess bacterial neurotoxins from metagenomic datasets, we found that phenylalanine decarboxylase (PDC) genes, mainly from Ruminococcus gnavus, increased approximately tenfold in patients with cirrhosis and higher in patients with HE. Cirrhotic, not healthy, mice colonized with R.

J Neurogastroenterol Motil
January 2025
Department of Gastroenterology, St Mark's Hospital, London, UK.
Background/aims: Buspirone shows promise in treating disorders of gut-brain interaction (DGBIs), particularly functional dyspepsia. However, findings have been mixed.
Methods: We systematically searched for prospective studies testing buspirone for any upper gastrointestinal DGBI in 4 databases (Cochrane, PubMed, Scopus, and PsycInfo).
Importance of Gut Microbiota Dysbiosis and Circadian Disruption-Associated Biomarkers in Emergence of Alzheimer's Disease.

Alzheimer's disease (AD) is a major devastating neurodegenerative disorder afflicting majorly the geriatric population. Emerging studies augur the connection of gut dysbiosis and circadian disruption with the early onset of AD. Gut dysbiosis is characterized by dysregulated gut microbiota signature and compromised intestinal integrity, which provokes the translocation of bacterial metabolites into the systemic circulation.

The gut-brain axis plays an integral role in maintaining overall health, with growing evidence suggesting its impact on the development of various neuropsychiatric disorders, including depression. This review explores the complex relationship between gut microbiota and glutamate (Glu) regulation, highlighting its effect on brain health, particularly in the context of depression following certain neurological insults. We discuss how microbial populations can either facilitate or limit Glu uptake, influencing its bioavailability and predisposing to neuroinflammation and neurotoxicity.
