Summary: The study found that gut microbiota composition significantly affects cigarette smoking-induced COPD development, and fecal microbiota transplantation can restore COPD pathogenesis. A beneficial bacterium Parabacteroides goldsteinii was isolated and shown to ameliorate COPD, with its derived active component having anti-inflammatory effects and ameliorating COPD through inhibition of lung inflammation and regulation of host metabolism.

Summary: This study aims to elucidate the characteristic change in the diversity and composition of gut microbiota in patients with rheumatoid arthritis (RA), in order to understand its role in the pathogenesis and progression of RA. A systematic search of multiple databases will be conducted, and case-control studies meeting the inclusion criteria will be independently screened. The quality of evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation framework. The results will be published in a peer-reviewed scientific journal and presented at conferences.

Summary: In the past, tumor and microbial infection were considered as independent diseases. However, the discovery of bacteria in tumor tissue changed this perception. Recent findings have shown the significant effects of bacteria on tumor development, metastasis, and immunity. Understanding the interactions between bacteria and tumors is crucial for developing new approaches for cancer treatment.

Summary: The aim of this study was to evaluate the effects of a probiotic mix composed of Bacillus subtilis, B. licheniformis, and benzoic acid on the zootechnical performance and hematoimmunological parameters of juvenile Nile tilapias. It was found that feed supplemented with 0.1% benzoic acid showed better results for weight gain, final biomass, specific growth rate, and survival after experimental challenge. Combined supplementation of the probiotic mix of Bacillus spp. and 0.1% benzoic acid promoted a synergistic effect on the concentration of total leukocytes.

Summary: Osteomyelitis is a bone infection that can spread through hematogenous, contiguous, or direct inoculation routes. Animal models can be used to study osteomyelitis, and different species are chosen for research. The clinical manifestation of hematogenous osteomyelitis varies due to multiple factors, but these variables can be controlled and tested through animal models.

Summary: AMP expression is a consistent feature of FK, with HBD-1 and -2 being most consistently expressed while LL-37 is the least, indicating a certain specificity of AMP expression related to FK. These results will aid in identifying HBD sequence templates for designing FK-specific peptides for potential therapeutic use.

Summary: This cross-sectional study examined the association between oral symptoms of gum bleeding and behavioral factors, beliefs, and knowledge among Hong Kong Chinese. The study found that approximately half of the participants reported experiencing gum bleeding, with 62.2% experiencing it within the past 12 months. Higher education levels were associated with greater awareness of gum problems. Individuals with bleeding gums, particularly those with periodontitis, poor dental awareness/behaviors, and/or a poor lifestyle should be targeted for education and encouragement to improve their gum health.

Summary: This article discusses the guidelines and ongoing research on environmental decontamination strategies for Candida auris, a multidrug-resistant fungal pathogen. The fungus's resistance to antifungal agents and ability to survive in healthcare settings make its eradication challenging. Current generic guidance lacks specific strategies for C. auris decontamination.

Summary: Obesity and periodontitis are common health concerns with negative relationships. Obesity leads to bone metabolic disorders and increased risks of periodontitis and alveolar bone loss. This review summarizes the clinical changes in periodontium and the biological interlinks in obesity-associated bone remodeling. The potential mechanism underlying obesity-enhanced alveolar bone loss is also discussed, providing practical considerations for managing periodontal disease in obese patients.

Summary: This review examines the effect of bifidobacterial probiotics on periodontopathogens and host immune responses. The use of different strains of bifidobacteria was found to reduce periodontopathogens, decrease inflammation, and improve clinical parameters. However, further research is needed before the therapeutic use of bifidobacteria in periodontal infections.

Summary: The proteomic profile of acquired pellicle on smooth bovine tooth and tooth-coloured restorative materials was evaluated and compared. It was found that significantly higher amounts of protein were adsorbed onto tooth surface. The protein quantity and composition of pellicles formed on different restorative material surfaces were similar, but distinct from the corresponding unstimulated whole saliva.

Summary: There has been a significant increase in the incidence of scarlet fever, especially in Europe, after the COVID-19 pandemic. Scarlet fever is caused by streptococcus pyogenes, which produces pyrogenic exotoxin and is responsible for over 500,000 deaths annually worldwide. Superantigens secreted by this bacteria can overstimulate the immune system, leading to symptoms such as sore throat, high fever, and a sandpaper-like rash. Dental practitioners should be aware of the early symptoms for timely diagnosis, treatment, and referral.
