It is difficult to differentiate pathogens from commensal organisms, and it is impossible to identify antibiotic resistance genes that belong to pathogens with current methods. Third-generation sequencing provides rapid library preparation and real-time data acquisition. Nanopore normal sampling (NNS) enables unbiased sequencing of clinical samples without amplification, aiding pathogen identification and antimicrobial resistance gene prediction. However, clinical samples often contain a considerable amount of human DNA, potentially masking pathogen data. Nanopore adaptive sampling (NAS) aims to selectively enrich pathogens, promising improved diagnostics for acute infections and better treatment decisions in clinical practice. This study aimed to determine the utility of NAS in enhancing the real-time detection of pathogens and predicting AMR in infectious disease outbreaks.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>This study used NAS technology to rapidly and directly detect <i>Mycoplasma pneumoniae</i> infection in bronchoalveolar lavage fluid samples from 28 pediatric patients at Shenzhen Children's Hospital.

High CEP55 expression was significantly associated with poor differentiation, deeper tumor invasion and increased lymph node metastasis in cancer patients. The pooled results indicated that elevated CEP55 expression can predict a poor overall survival (OS) and disease-free survival (DFS) in cancers. These results should be interpreted with caution because of publication bias.
