Oral and Fecal Microbial Dysbiosis as Non‐Invasive Diagnostic Biomarkers for Gastrointestinal Cancers: A Systematic Review and Meta‐Analysis of Diagnostic Accuracy

International Journal of Cancer, EarlyView.
ABSTRACT Gastrointestinal (GI) cancers, including esophageal (EC), gastric (GC), and colorectal cancer (CRC), impose a substantial global burden, with early detection remaining crucial for improving patient outcomes. The oral and gut microbiota are increasingly implicated in cancer development and hold promise as sources of non‐invasive biomarkers ...

Unlocking insights: Validating a comprehensive model for predicting spontaneous preterm delivery and microbial invasion in women facing preterm labor

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm labor is a multifactorial syndrome with diverse etiologies such as infection, inflammation, uteroplacental dysfunction, stress, and immune dysregulation. Identifying women at high risk remains a challenge, and multivariate prediction models have been developed to enhance risk stratification.

Susceptibilities of 394 Bacteroides fragilis, non-B. fragilis group Bacteroides species, and Fusobacterium species to newer antimicrobial agents [PDF]

Antimicrobial Agents and Chemotherapy, 1991
The susceptibilities of 374 selected beta-lactamase-producing gram-negative anaerobes (including 22 cefoxitin-resistant strains and 36 strains refractory to the enhancing effect of beta-lactamase inhibitors) and 20 beta-lactamase-negative strains were tested by agar dilution against selected new agents.

Bacteroides fragilis Prevents Clostridium difficile Infection in a Mouse Model by Restoring Gut Barrier and Microbiome Regulation

Frontiers in Microbiology, 2018
Clostridium difficile is currently the leading cause of nosocomial infection. Antibiotics remain the first-line therapy for C. difficile-associated diseases (CDAD), despite the risks of resistance promotion and further gut microbiota perturbation ...

Nutritional and environmental determinants of maturation and disruption of the early life gut microbiome: A narrative review

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract The first 1000 days of life represent a critical window for gut microbiome assembly, with lifelong implications for child growth, immune development, and disease risk. This review synthesizes evidence on maternal, perinatal, and especially nutritional factors that influence early‐life intestinal colonization and highlights the consequences of ...
