Summary: In recent decades, invasive candidiasis (IC) has become a significant cause of morbidity, mortality, and economic burden in the intensive care unit (ICU). The epidemiology of IC remains a difficult and unsolved puzzle for the literature. IC burden estimation is challenging due to various definitions and limitations in case-finding methodologies. Candidemia and intra-abdominal candidiasis (IAC) are the predominant types of IC in the ICU, with an increasing incidence of candidemia, particularly in elderly or immunosuppressed patients, and a shift towards non-albicans species worldwide.

Summary: This study found higher activity of convertases and carboxypeptidases in the saliva of preterm newborns, suggesting their importance for fetal development. However, aminopeptidase activity was not active in preterm newborns and only became active months after normal delivery. Further studies are encouraged to characterize the specific substrates of these enzymes.

Summary: Recent technological and analytical breakthroughs have enabled studies on small quantity, highly complex protein samples, such as salivary pellicle. Advances in mass spectrometry-based computational proteomics allow precise identification and quantification of complex protein samples, facilitating the determination of corresponding genes and cellular functions at the protein level through protein-protein interaction mapping. This has led to the breaking of barriers in research on small-quantity-complex-protein samples such as salivary pellicle.

Summary: The study found that salivary pellicles have a two-layer structure, and the change in ionic strength can affect this structure. Decreasing ionic strength leads to swelling of the outer layer and partial removal of the inner layer. The interaction between mucins and other pellicle components plays a crucial role in determining the structure of the pellicle.

Summary: The study investigated the clinical relevance of Candida hyphae in non-pseudomembranous oral candidiasis, revealing significant differences in clinical factors among different hyphae groups. It suggested that low-grade hyphae infection might represent a subclinical state of OC, and identified a new subtype named MNSC.

Summary: This study evaluated the performance of the commercially available OLM CandID real-time PCR in serum testing for invasive candidiasis (IC). The study found that CandID had excellent sensitivity and specificity, and when combined with (1-3)-beta-D-Glucan testing, it could accurately confirm or exclude IC.

Summary: Expanding the antifungal drug arsenal is crucial for treating Candida infections, which are increasing in prevalence and often resistant to existing treatments. This review provides a comprehensive summary of antimicrobial peptides (AMPs) with anti-Candida activity that have undergone successful preclinical or clinical trials. The source, mode of action, and animal model of infection or clinical trial for these AMPs are presented. The advantages of combination therapy using AMPs and other drugs to fight Candida infections are also discussed.

Summary: This study assessed the prevalence of oral colonization by Candida spp. in patients with psoriasis and the prevalence of oral lesions associated with Candida spp. It also identified the risk factors for oral lesions. The results showed that psoriatic patients had a higher risk of oral Candida colonization, especially those who received immunosuppressive therapies.

Summary: The study found that the composition of the salivary pellicle was more complex on rough surfaces (SLA and SLActive). Despite variation in protein composition between surfaces, most proteins were detected on more than one surface, indicating limited surface specificity for protein binding. The salivary pellicle formed on SLActive had a larger number of proteins associated with immune response, biological adhesion, and biomineralization.

Summary: The study aimed to quantify mandibular ramus height and condylar distances asymmetry indexes in adult patients with different vertical facial growth patterns using Cone Beam computed tomography (CBCT). The results showed significantly lower mandibular ramus height in individuals with a hyperdivergent skeletal pattern, but no statistically significant differences in condylar and intercondylar distances among different facial groups. Asymmetry indexes for mandibular ramus height and condylar distance were similar regardless of the skeletal patterns.

Summary: The study evaluated the effect of statherin and its naturally occurring peptides on Candida albicans metabolism and biofilm development. The peptides were found to decrease the viability and proliferation of Candida albicans, with IT-32 showing the most significant reduction in cell proliferation and biomass. These results suggest that statherin peptides have potential in reducing Candida albicans colonization and biofilm proliferation.

Summary: The engineered salivary peptide DR9-RR14 has been shown to effectively reduce enamel demineralization, but has no significant impact on biofilm biomass or the expression of cariogenic bacterial proteins. This suggests that DR9-RR14 may primarily control caries development through a physicochemical mechanism.

Summary: Salivary proteins play an important role in the repair of damaged tissues and the maintenance of oral health. This systematic review aimed to assess the association between caries and salivary proteins by comparing caries-free (CF) and caries-active (CA) individuals. The results showed that the levels of certain salivary proteins were significantly increased in CA patients, while others were significantly increased in CF subjects. However, there were conflicting results regarding the salivary levels of immunoglobulin-A and total proteins among CA and CF subjects. Due to significant heterogeneity among the included studies, no meta-analysis could be performed. Therefore, larger prospective studies are needed to verify the diagnostic value of salivary proteins as biomarkers for caries.
