Summary: The study evaluated the antifungal activity of three synthetic antimicrobial peptides (AMPs) against Candida species, including the multidrug-resistant Candida auris. The AMPs showed antifungal activity against all Candida species tested and had effects on biofilm formation and cell viability in C. auris and C. albicans. The study suggests that these AMPs are potential therapeutic alternatives against important Candida species.

Summary: Fungal infections have become a major problem in immunosuppressed or ICU patients, and the resistance of fungi to conventional antifungal treatments is increasing. This study evaluated the in vitro antifungal activity of LL-37 analogue peptides against Candida spp. The results suggest that LL37-1 and AC-2 have the best inhibitory effect on Candida strains.

Summary: This study investigated the antifungal effect of human beta defensin-1 (hBD-1) and its mechanism of action in Candida glabrata. The results showed that hBD-1 exhibited antifungal activity against C. glabrata and induced oxidative stress and cell cycle arrest. This suggests that hBD-1 has the potential to be developed as an antifungal drug.

Summary: Fungi cause disease in nearly one billion individuals worldwide, and current antifungal agents face challenges such as emerging and drug-resistant fungi, toxicity, and drug-drug interactions. The development of NP339, a polyarginine peptide with potent antifungal activity against various pathogenic fungi, presents a promising solution to these challenges. NP339 targets fungal cell membranes specifically, demonstrating rapid fungicidal activity without inducing resistance, suggesting its potential as a differentiated antifungal candidate for serious fungal diseases.

Summary: This study examined the antifungal activity of seven different human antimicrobial peptides (AMPs) against Candida auris, a multidrug-resistant yeast. The results showed that all tested peptides had fungicidal effects against C. auris at different levels. The peptides also showed synergistic interaction when combined with conventional antifungal drugs. These findings suggest that the tested peptides could be used as a monotherapy or in combination with antifungal drugs to treat multidrug-resistant C. auris infections.

Summary: Fluconazole use leads to the selection of resistant organisms, particularly in Candida glabrata. Elevated minimal inhibitory concentrations for fluconazole in C. glabrata are associated with mutations in the PDR1 gene. Calcineurin, a protein phosphatase, is required for the induction of PDR1 transcriptional regulation by fluconazole, and it links azole and echinocandin susceptibility together through the control of transcription factor activity.

Summary: Systemic infections caused by Candida glabrata pose a significant threat to both immunocompromised and non-immunocompromised patients, with increasing resistance to traditional antifungal therapies. Ibrexafungerp, a first-in-class glucan synthase inhibitor, shows promising broad-spectrum activity against C. glabrata, including drug-resistant strains, and has potential for treating vulvovaginal candidiasis. Further preclinical and clinical studies are needed to explore its mechanisms and evaluate its efficacy as a new agent for C. glabrata infections.

Summary: The study evaluated the use of ionic liquids (ILs) as functional excipients for solubilizing and stabilizing diacerein (DIA) in eye drop formulations and prolonging its ocular residence time. Two ILs based on natural zwitterionic compounds were investigated: L-carnitine C6 alkyl ester bromide (Carn6) and betaine C6 alkyl ester bromide (Bet6). The ILs demonstrated solubilizing, stabilizing, mucoadhesive, and antimicrobial properties, with potential for future use in ophthalmic applications.

Summary: Despite being investigated as a host-directed therapy in treating tuberculosis, Everolimus showed no direct or indirect activity against Mycobacterium tuberculosis (Mtb). Even in an immunosuppressed patient, Everolimus did not affect the viability of Mtb and had minimal impact in host cells during infection. This case emphasizes the importance of careful drug repurposing and pre-clinical experimental studies.

Summary: It was previously believed that the human bladder is sterile, but recent advances in molecular biology have shown the presence of microorganisms in the urinary tract. Understanding the relationship between urobiota and urinary tract disorders has become a significant research focus. Patients with spina bifida (SB), a condition that can lead to neurogenic bladder and increased susceptibility to urinary tract infections, often undergo clean intermittent catheterization (CIC) for treatment. This study aims to investigate the urobiota composition in SB patients compared to healthy controls and explore the urobiota characteristics in relation to CIC.

Summary: This study investigated the effectiveness of gut microbiota modulation for enhancing recovery after COVID-19. A pilot interventional study was conducted with twenty recently recovered COVID-19 patients to explore the impact of a mixed probiotic containing Lactobacilli, Bifidobacteria, and Streptococcus thermophilus on gastrointestinal symptoms, inflammation, intestinal barrier integrity, and gut microbiota profile. Various markers and computational algorithms were utilized to evaluate the outcomes before and after 8 weeks of probiotic supplementation. The results showed a significant reduction in inflammatory markers and an increase in Bifidobacteria at T-1, indicating potential anti-inflammatory effects and the influence of probiotics on gut microbiota composition.

Summary: Acute respiratory distress syndrome (ARDS) is a severe complication of lung injuries, often caused by various infections. ARDS is associated with high mortality and lacks effective treatment. In this study, the efficacy of mesh nebulisation of plasminogen (PLG) for off-label administration as an ARDS treatment was investigated. Results showed that aerosolised PLG demonstrated optimal deposition, maintained enzymatic activity, and had immunomodulating effects.

Summary: The use of salivary swabs (SS) to detect SARS-CoV-2 in adults and children during the COVID-19 pandemic has been widely studied. However, the role of SS in detecting other respiratory viruses in children is not well investigated. This study found that SS has a relatively low sensitivity in detecting common respiratory viruses in children, especially in younger children or those with smaller amounts of saliva collected. New strategies to improve saliva collection are needed for testing on a larger study population.

Summary: The human gut microbiome plays a significant role in human health and disease development. Recent advancements in technology have allowed for a better understanding of its composition and functions. Diet, specifically, has been found to shape the gut microbiome, affecting its diversity, population size, and metabolism. Personalized nutrition, based on individual characteristics, has shown promise in directly impacting the gut microbiome. Longitudinal studies are necessary to fully comprehend the long-term effects of specific diets and food components on the gut microbiome, as well as the variations between individuals. Accurate methods of collecting dietary data and the application of machine learning techniques hold immense potential in understanding the gut microbiome's response to diet and providing tailored lifestyle recommendations.

Summary: Researchers have created a delivery system for cinnamaldehyde (CIN) using PLGA microparticles (CIN-MPs) to combat antibiotic resistance of microorganisms. The conveyed CIN increased the antifungal effects, especially against antibiotic-resistant strains of Candida spp. The slow and prolonged release of CIN from the PLGA MPs ensured a constant and uniform concentration within the cells.

Summary: In this retrospective study, antibody immunity in candidemia patients was evaluated by analyzing sera taken at candidemia diagnosis. The presence of IgG antibodies against Candida antigens Als3, Mp65, Hyr1, and Eno1 were observed in all patients at significantly higher levels compared to non-candidemia controls. Antibodies against Als3 and Mp65 were found to be associated with lower 30-day patient mortality. Multivariable logistic regression analysis showed that the antibody response against Als3 and Mp65, along with other variables, could accurately predict candidemia outcome.
