The rates and severity of Clostridium difficile infections, including pseudomembranous colitis, have increased markedly. However, there are few effective treatments for refractory or recurrent C. difficile infections and the outcomes are poor. Fecal microbiota transplantation is becoming increasingly accepted as an effective and safe intervention in patients with recurrent disease, likely due to the restoration of a disrupted microbiome. Cure rates of >90% are being consistently reported from multiple centers. We cured a case of severe refractory C. difficile infection with fecal microbiota transplantation in a patient colonized by vancomycin-resistant enterococcus.

Background: Gut microbiota modulation of the brain function may present an opportunity to devise preventive or treatment strategies to manage impairments such as cognitive frailty (CF). This study aims to uncover the relationship between CF, gut microbiota, intestinal permeability and proteome.
Method: A total of 137 fecal samples of the elderly were collected, and subjected to DNA analysis, and enzyme-linked immunosorbent assays (ELISA).

Background: Research heavily suggests that brain-derived neurotrophic factor (BDNF), vital for neuronal growth and plasticity, and cholecystokinin (CCK), a satiety hormone that regulates BDNF levels, are altered in Alzheimer's Disease pathophysiology. Factors such as dysbiosis of gut microbiota and poor food habits may affect CCK and BDNF release and brain function. The objective is to evaluate the effects of dietary habits, gut microbiota, and exercise on BDNF and CCK release in Alzheimer's Disease patients.

The gut microbiota plays a pivotal role in anxiety regulation through pathways involving neurotransmitter production, immune signaling, and metabolic interactions. Among these, gut-derived serotonin (5-hydroxytryptamine, 5-HT), synthesized from tryptophan metabolism, has been identified as a key mediator. However, it remains unclear whether specific microbial factors regulate tryptophan metabolism to influence 5-HT production and anxiety regulation.

Background: Spousal care partners to people with dementia (PWD) have a higher rate of depression and anxiety when compared to similar age controls. Previous studies have suggested a role of gut microbiota in the pathophysiology of neuropsychiatric symptoms and Alzheimer's disease (AD). Thus, our study aims to: (1) determine the presence and severity of depression and anxiety in care partners of PWD, and (2) determine the concentrations of short chain fatty acids (SCFA), which are mainly produced by gut microbiota and are important in mediating gut microbiota effects, in the blood of care partners of PWD.

Early gut microbiome development may impact brain and behavioral development. Using a nonhuman primate model (), we investigated the association between social environments and the gut microbiome on infant neurodevelopment and cognitive function. Infant rhesus monkeys ( = 33) were either mother-peer-reared (MPR) or nursery-reared (NR).
