Congenital lower urinary tract obstruction (CLUTO) is a spectrum of fetal malformations caused by anatomical abnormalities of the urethra, characterized by high rates of perinatal complications and mortality. The 2024 joint guideline from the European Association of Urology (EAU) and the European Society for Paediatric Urology (ESPU) introduced systematic revisions to the comprehensive management of CLUTO. Key updates encompass advancements in prenatal and postnatal screening and precise diagnosis, refined fetal prognosis assessment, clearer indications and modality selection for prenatal intervention, optimization of postnatal treatment strategies, and the establishment of a lifelong follow-up framework within an integrated care pathway. This article elucidates these key updates by comparing the 2024 EAU/ESPU guideline with the 2022 European Rare Kidney Disease Reference Network (ERKNet) consensus. It also discusses ongoing controversies and future research directions. The aim is to provide clinicians with the latest evidence-based insights to inform practice, ultimately improving outcomes and quality of life for children with CLUTO.

2.Progress in the role of neutrophil extracellular traps in sepsis and organ dysfunction
Chinese Journal of Microbiology and Immunology 2025;45(3):264-268
Sepsis is a clinical syndrome resulting from infection followed by inflammation and is one of the significant causes of mortality worldwide. The underlying reason is the host′s uncontrolled inflammatory response to an infection, which leads to multiple organ dysfunction. It not only aggravates the condition, but also leads to a poor prognosis. Neutrophils are involved in many physiological and pathological processes in the human body and are forerunners to reach the site of infection/inflammation for clearing the infection and resolute the inflammation during sepsis. In addition, under the stimulation of pathogens, neutrophils can release a special network structure containing a variety of protein components and DNA as the skeleton, which is named neutrophil extracellular traps (NETs). Although NETs can kill pathogens, excess NETs have a significant influence on the pathogenesis of sepsis-induced multiple organ damage, including lung, kidney, and liver damage. This review aims to introduce the role of NETs in sepsis and organ dysfunction, hoping to provide new ideas for the treatment of sepsis.

Objective:To investigate the incidence of hearing loss among helicopter flying personnel, and to analyze the contributing factors.Methods:Basic data of 443 male helicopter flying personnel who received physical examinations at Beidaihe Rehabilitation and Recuperation Center of PLA between March and June 2024 was collected. The hearing threshold levels were measured at 8 frequencies: 250, 500, 1 000, 2 000, 3 000, 4 000, 6 000 and 8 000 Hz. Routine blood tests and blood biochemical tests were performed. Based on the results of pure-tone audiometry, the participants were divided into 2 groups: the hearing loss group (hearing threshold ≤20 dB HL) and the normal hearing group (hearing threshold >20 dB HL). The basic data, routine blood results, and blood biochemical indicators were compared between the 2 groups before the contributors to hearing loss were analyzed.Results:A total of 443 helicopter flying personnel were included in the study, with 82 cases (18.51%) in the hearing loss group and 361 cases (81.49%) in the normal hearing group. There were significant differences in age and pulse between the flying personnel in the 2 groups ( t=2.13, 2.78, P=0.034, 0.006). Among the blood routine indicators, only the mean platelet volume (MPV) was significantly different ( t=2.26, P=0.025). Among the blood biochemical indicators, only homocysteine (HCY) revealed statistically significant difference ( Z=2.30, P=0.021). The determinants of hearing loss in helicopter flying personnel were age ( OR=1.046, 95% CI: 1.060-1.361), pulse ( OR=1.201, 95% CI: 1.060-1.361), MPV ( OR=1.365, 95% CI: 1.016-1.834) and HCY ( OR=1.065, 95% CI: 1.033-1.097). Conclusions:Age, pulse, the MPV and HCY levels can all contribute to hearing loss, and the MPV and HCY can serve as potential biomarkers for hearing loss in helicopter flying personnel. Potential hearing loss should be detected early and personalized interventions should be implemented. Noise exposure should be monitored more rigorously to reduce the risk of occupational hearing loss for helicopter flying personnel and ensure flight safety.

Objective:To analyze the results of next generation sequencing (NGS) gene testing in liquid-based cytological specimens of lung adenocarcinoma cavity and evaluate the clinical efficacy of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) treatment.Methods:Liquid based cytological specimens of 222 cases of lung adenocarcinoma with cavity effusion and 201 cases of metastatic lymph node biopsy were collected. Specimens were obtained from the Cytology Laboratory of the Cancer Hospital of the Chinese Academy of Medical Sciences. The collection period was from January 2018 to December 2022. The results of NGS gene detection were compared. The clinical efficacy of 91 patients treated with EGFR-TKI was evaluated, and the survival curve was analyzed by Kaplan-Meier and other statistical methods.Results:The mutation rates of cancer-related genes detected by NGS were 82.0% (182/222) vs 79.1% (159/201), ( P=0.455) in liquid-based cytological specimens and histological specimens of metastatic lymph node biopsy, respectively. However, the mutation rate of EGFR T790M was significantly higher in cavity effusion than in lymph node biopsy specimens [12.2%(27/222)>3.5%(7/201), P=0.001]. The results of gene mutation were identical in 10 of the 13 cases with cavity effusion and metastatic lymph node biopsy, and the agreement rate of EGFR was 84.6%(11/13). In 3 inconsistent cases, EGFR mutations were detected in 2 cavity effusion cases that were not detected by lymph node biopsy. Results of genetic analysis of fluid-based cytological samples of 91 patients with cavity effusion were evaluated after drug treatment with EGFR-TKI. The mean progression-free survival (PFS) of the patients was 11.4 months (95% CI: 9.9-12.9). The mean PFS of patients harboring EGFR mutation was 12.3 months (95% CI: 10.8-13.9), and the mean PFS of EGFR wild type was 4.1 months (95% CI: 2.1-6.2). Conclusions:The results of NGS gene detection in liquid-based cytological specimens of lung adenocarcinoma patients with cavity effusion show that the PFS time is similar to that of histological specimens after clinical treatment with EGFR-TKI, which proves the reliability of NGS gene detection results in liquid cytological specimens. NGS gene testing appears higher sensitivity in cavity liquid-based samples than in metastatic lymph node samples.

Objective:To analyze the influencing factors of severe dengue fever patients in the early stage, construct a early prediction model for severe dengue fever, and evaluate it.Methods:A retrospective analysis was conducted to collect early clinical data of dengue fever patients admitted to the People's Hospital of Mengla County and the Third People's Hospital of Kunming in Yunnan Province from July to December 2023. The multifactor logistic regression was used to analyze the factors affecting the severe dengue fever patients, and Nomogram prediction model was used for visualization. Receiver operating characteristic (ROC) curve and calibration curve analysis were used to evaluate the model.Results:A total of 534 dengue fever patients were included, including 291 males and 243 females, aged (39.95 ± 15.69) years. Among them, there were 59 cases (11.05%) of severe dengue fever. The results of multifactor logistic regression analysis showed that age ( OR = 1.05, 95% CI: 1.02 - 1.08, P < 0.001), cardiovascular disease ( OR = 5.28, 95% CI: 2.08 - 13.40, P < 0.001), serous effusion ( OR = 4.34, 95% CI: 1.63 - 11.57, P = 0.003), aspartate aminotransferase ( OR = 1.03, 95% CI: 1.02 - 1.04, P < 0.001), lactate dehydrogenase ( OR = 1.00, 95% CI: 1.00 - 1.01, P = 0.001), and fibrinogen ( OR = 0.46, 95% CI: 0.28 - 0.76, P = 0.003) were independent influencing factors in the early stage of severe dengue fever. The area under the ROC curve of the Nomogram prediction model constructed from the above six variables was 0.96 (0.93 - 0.98). The calibration curve analysis results showed that the mean absolute error between the predicted values of the Nomogram prediction model and the actual observed values was 0.014. Conclusions:Age, cardiovascular disease, serous effusion, aspartate aminotransferase, lactate dehydrogenase, and fibrinogen are independent influencing factors in the early stage of severe dengue fever. The Nomogram prediction model established based on these variables has good predictive ability for severe dengue fever.
