A total of 35 patients experiencing knee pain were included in the study. IA-bPRF was applied at 42 °C temperature, 45 V, with a pulse-width of 20 ms and a frequency of 2 Hz for 3 cycles of 120 seconds. Pain severity was evaluated using the numeric rating scale. Assessment tools included Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne Algofunctional Index for knee. All measurements were made before the intervention, as well as 2 weeks and 6 months after application of IA-bPRF. Significant improvement was observed in numeric rating scale scores for walking pain from 8.57 ± 0.17 to 4.11 ± 0.35, total WOMAC scores decreased from 75.5 ± 2.71 to 36.7 ± 3.6 and Lequesne Algofunctional Index for knee scores decreased from 18.6 ± 0.70 to 10.4 ± 0.93 by the end of the sixth month (P < .01).

The dorsolateral prefrontal cortex sn-RNA-Seq dataset (GSE243292) was sourced from the Gene Expression Omnibus (GEO) database. Data preprocessing was conducted using the Seurat R software package, employing principal component analysis (PCA) and uniform manifold approximation and projection (UMAP) for cell clustering and annotation. MR analysis was used to identify instrumental variables from expression quantitative trait loci (eQTL) and GWAS data by applying inverse variance weighting (IVW), weighted median (WM) and MR-Egger methods. This was complemented by leave-one-out sensitivity analysis to validate the causal relationship on AD risk genes. We identified 23 distinct cell clusters, which were annotated into eight subgroups, including oligodendrocytes, oligodendrocyte precursors, astrocytes, macrophage cells, endothelial cells, glutamatergic neurons, neural stem cells, and neurons. Notably, the number of macrophages significantly increased in the AD group. Using genome-wide association study (GWAS) summaries and eQTL data, MR analysis identified causal relationships for 7 genes with significant impacts on AD risk. Among these genes, CACNA2D3, INPP5D, RBM47, and TBXAS1 were associated with a decreased risk of AD, whereas EPB41L2, MYO1F, and SSH2 were associated with an increased risk. A leave-one-out sensitivity analysis confirmed the robustness of these findings. Expression analysis revealed that these genes were variably expressed across different cell subgroups. Except for the CACNA2D3 gene, the other 6 genes showed increased expression levels in the macrophages, particularly EPB41L2 and SSH2.

We retrospectively analyzed 7326 P. aeruginosa isolates collected from diverse clinical sources in a tertiary hospital in Zhejiang Province from 2005 to 2023. Identification and antibiotic susceptibility testing of each isolate were performed using the VITEK-32 automated system and the disk diffusion method, following Clinical and Laboratory Standards Institute guidelines. We assessed resistance patterns for key antibiotic classes relevant to P. aeruginosa treatment, including carbapenems, β-lactams, aminoglycosides, and quinolones. Statistical analyses, including trend evaluations and resistance determinant assessments, were conducted in R software (version 4.2.2), with visualizations generated through ggplot2 to illustrate resistance trends over time. This study focused on key anti-pseudomonal agents including carbapenems (imipenem and meropenem), β-lactams (piperacillin), and quinolones (ciprofloxacin and levofloxacin). We observed a progressive increase in resistance to imipenem from 6.8% in 2005 to 48.2% in 2023 and meropenem from 25.4% to 44.2% over the same period. Conversely, resistance rates to aminoglycosides declined, with gentamicin resistance dropping from 22.0% in 2005 to 5.0% in 2019. Cephalosporins exhibited variable trends, with cefepime resistance peaking at 40.4% in 2013 before declining to 12.1% in 2023. The findings indicated a progressive increase in resistance rates for these antibiotics, with notable peaks coinciding with changes in clinical practices and the COVID-19 pandemic. The analysis demonstrated that shifts in prescription habits, particularly during the COVID-19 pandemic, influenced resistance patterns, underscoring the need for context-specific antimicrobial stewardship strategies. This study identifies significant, evolving resistance patterns in P. aeruginosa over a 19-year period, with marked increases in resistance to critical antibiotics, including carbapenems (imipenem, meropenem), quinolones (levofloxacin, ciprofloxacin), and certain β-lactams (piperacillin). These findings underscore an urgent need for dynamic, tailored infection control measures, emphasizing the importance of robust antibiotic stewardship programs, localized treatment guidelines, and proactive monitoring of resistance trends.
