This article reviews the latest evidence on the use of antibiotics in dentistry, beginning with the risks of antibiotic use, which include Clostridioides difficile infection and antimicrobial resistance. The article then reviews the clinical practice guidelines for antibiotic prophylaxis for patient …

The gut-brain axis is gaining more attention in neurodevelopmental disorders, especially autism spectrum disorder (ASD). Many factors can influence microbiota in early life, including host genetics and perinatal events (infections, mode of birth/delivery, medications, nutritional supply, and environ …

Ulcerative colitis (UC) is a chronic inflammatory intestinal disease affecting the colon and rectum, with its pathogenesis attributed to genetic background, environmental factors, and gut microbes. This study aimed to investigate the role of enterotypes in UC by conducting a hierarchical analysis, d …

The study revealed alterations in microbiota compositions and short-chain fatty acid concentration in cats suffering from chronic enteropathy, which is an important finding both for research on the pathogenesis of the disease and for potential therapeutic interventions in the form of faecal microbio …

Diosgenin, a natural steroid saponin, holds promise as a multitarget therapeutic for various diseases, including neurodegenerative conditions. Its efficacy in slowing Alzheimer's disease, Parkinson's disease, multiple sclerosis, and stroke progression has been demonstrated. However, the role of dios …

Sex-Discordant Fecal Microbiota Transplantation for Clostridioides difficile May Increase Risk of Postinfection Irritable Bowel Syndrome

Certain intestinal microbiota alterations appear to positively correlate with tumorigenesis of CAC due to the disruption of the balance between the host and microorganisms. It is proven that blocking MyD88 signaling can prevent colitis-associated colorectal cancer (CAC) development in mice. We are a …

The intestinal microbiota drives the maturation of the immune system, which is essential for maintaining lifetime homeostasis. Whether fecal microbiota transplantation can promote the development of the immune system in chicks? On days 1, 3, and 5, the post-hatch Hy-line Brown chicks were treated wi …

Clostridioides difficile infection presents a unique treatment paradox for clinicians: Antibiotics are often both its cause and its cure.Broad-spectrum antibiotics used to treat infections radically alter the composition of a patient’s microbiota, wiping out a significant portion of the bacterial community and upsetting the natural balance of gut flora. Without competition from healthy

With the aim of discovering small molecule inhibitors of the sporulation process in Clostridioides difficile, we prepared a series of C-7 α-(4-substituted-1H-1,2,3-triazol-1-yl)acetamide analogues of cefotetan, a known inhibitor of the C. difficile sporulation-specific protein t …

Fidaxomicin (in seven studies) demonstrated significant improvement in achieving sustained clinical cure. A limitation of this study may that more studies are needed to compare fidaxomicin with other antibiotics.

Clostridium difficile (Clostridioides difficile) is a leading cause of nosocomial infections in hospitalized patients worldwide. Stool samples were collected from 112 inpatients admitted to different hospitals and were screened for C. difficile GDH + toxin A + B by immunoassay, …

FRIDAY, July 21, 2023 (HealthDay News) -- Aspirin, naproxen and other common pain medications known as NSAIDs worsen gastrointestinal infections caused by a bac

Scientific Reports - Genetic variation in the human leukocyte antigen region confers susceptibility to Clostridioides difficile infection

Colitis induced by treatment with immune checkpoint inhibitors (ICI), termed irColitis, is a substantial cause of morbidity complicating cancer treatment. We hypothesized that abnormal fecal microbiome features would be present at the time of irColitis onset, and that restoring the microbiome with f …

Nature Medicine - A cluster randomized trial in Tanzania showed that the implementation of a decision support algorithm decreased antibiotic prescriptions to children considerably, without...

This review summarizes mechanisms underlying microbiota-gut-brain axis and novel therapeutic opportunities for neurological sequelae in preterm infants. Optimizing the initial colonization and microbiota development in preterm infants may represent a novel therapy to promote brain development and re …

Objective The novel coronavirus disease 2019 (COVID-19) pandemic has spread worldwide, and hospitals in Japan have been forced to respond to the situation. This study evaluated the broad-spectrum antimicrobial use before and during the COVID-19 pandemic in an acute tertiary-care hospital. Methods Th …

Clostridioides difficile infection (CDI) is a major cause of healthcare-associated diarrhea, despite the widespread implementation of contact precautions for patients with CDI. Here, we investigate strain contamination in a hospital setting and genomic determinants of disease outcomes. Across …

Make sure to disinfect beds properly after they are used by someone with Clostridioides difficile, or C. diff. According to a new study, staying in a bed previously used by a person with C. diff raises the risk that they’ll get the infection.

Stool-derived products and bacterial consortia need to be clearly distinguished in terms of product characterization and their associated risks with specific long-term post-marketing evaluation similar to registries used for FMT. Their place in the therapeutic strategy for patients with rCDI require …

Therefore, B. acidifaciens and its derived EVs can alleviate DSS-induced colitis by reducing mucosal damage to colon tissue, reducing inflammatory response, promoting mucosal barrier repair, restoring gut microbiota diversity, and restoring gut microbiota balance in mice. The results of this …

Vowst's FDA approval is a boon for the prevention of recurrent Clostridioides difficile infection

Here, we show that levels of fecal short-chain fatty acids (SCFAs), particularly butyrate, are reduced, and normal colon structure is damaged in patients with CDI compared with those in healthy individuals. Bile acid (BA) metabolic disorder in patients ...

In Greece, the stark increase in Clostridioides difficile (C. diff) incidence cannot be explained by a rise of antimicrobial use during the pandemic.

The FDA approved VOWST to prevent recurrence of C. difficile infection. The approval is based on a trial in which UC Davis Health’s Stuart Cohen served as principal investigator.

Intestinal bile acids play an essential role in the Clostridioides difficile lifecycle having been shown in vitro to modulate various aspects of pa...
