Summary: Chronic wound management is a major challenge in healthcare due to its slow healing process and high financial burden. Traditional wound dressings are not effective for highly exudating chronic wounds, necessitating the development of newer dressings. This review provides an overview of modern wound dressings and their in vitro and in vivo characterization methods, highlighting their advantages, challenges, and future outlook.

Summary: Derived from AP-2 complex subunit mu-A, the short peptide AP10W exhibits notable antifungal activities against Candida albicans and Aspergillus fumigatus. It inhibits fungal biofilm formation and reduces pre-established fungal biofilms. AP10W acts through various mechanisms including interaction with fungal cell walls, enhancement of cell wall permeability, membrane depolarization induction, and increase in intracellular ROS generation. It shows low toxicity towards mammalian cells and promotes wound healing in C. albicans-infected skin.

Summary: The use of silver diamine fluoride (SDF) has been shown to significantly reduce the growth of bacterial biofilms, indicating its potential as an effective treatment for dental caries. Further research is advised to explore the potential of SDF as a standard therapy choice for dental caries and to further investigate its relationship with bacterial biofilms.

Summary: DJK-5 treatment quickly killed biofilm bacteria and maintained a high level of dead bacteria for 1 week, while 1018 and CHX had less effective results, and the proportion of dead bacteria doubled within the first 7 days after exposure to CHX and 1018. The recovery time of biofilms was slow but similar after exposure to different treatments, with the recovery time after exposure to DJK-5 being longer.

Summary: This study compared the efficacy of double manual cleaning with enzymatic detergent followed by alkaline detergent on biofilm removal on hinged surgical instruments to automated cleaning. The results showed that both double manual cleaning with hinge brushing and automated cleaning effectively removed biofilm and residual protein. Additionally, there was no significant difference in efficacy between double manual cleaning with hinge brushing and automated cleaning.

Summary: The development and health of infants are closely linked to the gut microbiota, which acts as a protective and regulatory system. Imbalances in the gut microbiota in preterm infants can increase the risk of various diseases. This review examines the role of the probiotic Bifidobacterium in the development of gut microbiota and prevention of diseases in preterm infants, as well as its mechanisms of action.

Summary: Staphylococcus aureus biofilms exhibit resistance to antibiotics and disinfectants, which is attributed to changes in the bacterial cell wall. Proteins involved in cell wall synthesis are upregulated in biofilms compared to planktonic organisms. Furthermore, the width of the cell wall and peptidoglycan production increase with biofilm culture duration and dehydration. Disinfectant tolerance is highest in dry surface biofilms, followed by hydrated biofilms, and lowest in planktonic bacteria, indicating that changes in the cell wall may contribute to the biocide resistance of S. aureus biofilms.

Summary: This systematic review provides a comprehensive understanding of the gut microbiota composition in patients with Parkinson's disease and Alzheimer's disease compared to healthy controls. The study found significant differences in gut microbiota composition between patients and healthy controls, as well as specific changes in abundance of certain bacterial taxa. The microbial diversity evaluations also revealed differences between the case and control groups. These findings offer promising prospects for the management and treatment of Parkinson's disease and Alzheimer's disease.

Summary: This narrative review proposes that neuroinflammation in Alzheimer's disease (AD) may be partially caused by external pathogens entering the brain through the nose and the olfactory system. The olfactory system represents a plausible route for pathogen entry, and accidental exposure of the olfactory mucosa to hands contaminated with soil and feces when picking one's nose is one potential mechanism.
