Article Abstract
Complications of end-stage renal disease (ESRD) are critically related to inflammation. The gut microbiome is a key driver of inflammation. Since dialysis modalities may differently influence the gut microbiome, we aimed to compare the effects of haemodialysis (HD) and peritoneal dialysis (PD) on patients' gut microbiome composition and function. We therefore studied faecal microbiome composition and function as well as inflammation and gut permeability in 30 patients with ESRD (15 HD, 15 PD) and compared to 21 healthy controls. We found an increase in potentially pathogenic species and a decrease in beneficial species in patients on HD and to a lesser extend in patients on PD when compared to controls. These changes in taxonomic composition also resulted in differences in predicted metagenome functions of the faecal microbiome. In HD but not in PD, changes in microbiome composition were associated with an increase in c-reactive protein (CRP) but not with intestinal inflammation or gut permeability. In conclusion microbiome composition in ESRD differs from healthy controls but also between modes of dialysis. These differences are associated with systemic inflammation and cannot completely be explained by dialysis vintage. The mode of renal replacement therapy seems to be an important driver of dysbiosis in ESRD.

Sleep deprivation (SD) is a major contributor to cognitive impairment, often accompanied by central neuroinflammation and gut microbiota dysbiosis. The tryptophan (TRP) pathway, activated via indoleamine 2,3-dioxygenase (IDO), serves as a critical link between immune activation and neuronal damage. Umbelliferone (UMB), a naturally occurring coumarin compound, possesses anti-inflammatory, antioxidant, and microbiota-modulating properties.

Enterotoxigenic Escherichia coli (ETEC) is a prevalent intestinal pathogen that significantly impacts both human and animal health. G83, isolated from giant panda feces, has demonstrated notable probiotic properties. In this study, C57BL/6 J mice were randomly divided into Control, ETEC, and G83 groups.

Parity, the number of pregnancies carried beyond 20 weeks, influences the maternal gut microbiome. However, whether parity modulates the infant microbiome longitudinally remains underexplored. To address this, 746 infants in a longitudinal cohort study were assessed.

The human microbiota consists of millions of microorganisms, predominantly bacteria, that inhabit the body and form communities. Each human body site has a unique population that is specifically adapted to complement the metabolic functions of the environments in which they are present. These microbial communities begin to form at birth, with their primary establishment occurring during the early years of childhood and persisting in adulthood.

Purpose: Emerging evidence suggests that an abnormal endometrial microbiota may be a potential factor contributing to recurrent pregnancy loss (RPL). This study aimed to characterize the endometrial microbiota in patients with RPL and to explore its association with miscarriage.
Patients And Methods: Based on specific inclusion and exclusion criteria, EndoMetrial Microbiome Assay (EMMA) data from women attending clinics were collected and categorized into RPL and control groups according to their miscarriage history.
