Objective:To analyze the clinical characteristics, treatment strategies, and prognostic outcomes of patients infected with Listeria monocytogenes, thereby providing evidence-based insights for the prevention and control of this disease.Methods:A retrospective analysis was performed on the clinical data, diagnostic tests, treatment protocols, and prognostic outcomes of patients definitively diagnosed with Listeria monocytogenes infection at Sichuan Provincial People's Hospital over the past decade. Additionally, a comprehensive literature review was conducted, encompassing studies published between 2014 and 2024, sourced from CNKI, Wanfang Data, and PubMed. This review focused on summarizing the clinical features, treatment regimens, and prognostic outcomes of patients with Listeria monocytogenes infection.Results:The study cohort comprised 17 patients, with a mean age of (61.29 ± 16.24) years. The confirmed cases included 7 cases of bloodstream infections, 3 cases of central nervous system infections, and 7 cases of combined infections. Sepsis developed in 9 patients. The average time from symptom onset to the initiation of empirical antibiotic therapy was 72 hours, while the mean time to definitive diagnosis was 102 hours. Antimicrobial regimens predominantly featured penicillins, meropenem, and vancomycin. The average hospitalization duration was 16 days, with 9 patients experiencing adverse outcomes. A total of 78 relevant literature pieces were retrieved, encompassing data from 85 patients. The average age of these patients was (57.96 ± 16.48) years. Primary diagnostic methods relied on blood/cerebrospinal fluid cultures and Next-Generation Sequencing (NGS). Treatment regimens primarily involved antibiotics such as penicillins, aminoglycosides, carbapenems, and glycopeptides. Despite these interventions, the proportion of patients with poor prognosis remained significantly high at 30.6% (26/85). Logistic regression analysis identified sepsis and delayed antibiotic administration as independent predictors of poor prognosis.Conclusions:Listeriosis, caused by an opportunistic pathogen, necessitates early antibiotic administration and timely identification of at-risk populations to mitigate the risk of poor prognostic outcomes in patients.

Objective To search for independent predictive factors of diabetic kidney disease(DKD)in patients with type 2 diabetes mellitus(T2DM),construct and validate an optional machine learning(ML)model for the risk of DKD.Methods A total of 528 patients with T2DM,hospitalized in the Endocrinology Department of Chengde Central Hospital from October 2019 to September 2020,were selected as the study objects,and patients were randomly divided into a training set(370 cases),and a validation set(158 cases).The training set was divided into the DKD group(89 cases)and the non-DKD group(281 cases)according to whether DKD existed.The general data and diagnostic examination of patients were performed by univariate analysis,in which variables with statistical differences were used to screen the best predictors by least absolute shrinkage and selection operator(LASSO)regression analysis.The best predictors were used to establish eight ML algorithms by three cross-validation methods,including Logistic regression(LR),K-nearest neighbor(KNN),support vector machine(SVM),decision tree(DT),random forest(RF),naive Bayes(NB),artificial neural network(ANN),and extreme gradient lift(XGBoost).The optimal prediction model was selected by receiver operating characteristic(ROC)curve,Delong test and GiViTI calibration curve.Decision curve analysis(DCA)was used to evaluate the clinical practicability of the model.Results Age,alanine aminotransferase,creatinine,triglyceride,cystatin C,25-hydroxy vitamin D and monocyte count were independent predictive factors of DKD.Eight ML models were established based on the above 7 predictors,and the ANN model performed best in the 8 ML models.The GiViTiI calibration curve indicated that the model had good accuracy(P>0.05),and the DCA showed that the prediction model curve had clinical practical value in the threshold probability range of 0.027-0.612.Conclusion In this study,the ANN model constructed in this study to predict the risk of DKD is helpful for early discrimination of high-risk T2DM patients with DKD.

Urodynamics is a critical field that studies the physiological and biomechanical parameters involved in urine production, storage, and voiding.This paper first reviews the development process of urodynamics, expounds the development and progress of urodynamic testing instruments from early basic research to modern advanced equipment and the history of their introduction into China, and then introduces in detail the principle of action, system composition and clinical application status of major urodynamic instruments, and further points out the technical shortcomings of current instruments, and then proposes improvement directions, including the core load sensor technology, comfort and privacy of urodynamic testing instruments, work data transfer and close integration with artificial intelligence, in order to provide a valuable reference for clinical understanding of the development of this field.

Purpose:
Erectile dysfunction (ED) is associated with several vascular disorders, but the associations between ED and vascular parameters are still unclear.
Materials and Methods:
We analyzed and synthesized a comprehensive range of studies from PubMed, Web of Science, and Scopus regarding the associations between ED and the following measures: ankle-brachial index (ABI), pulse wave velocity (PWV), intima-media thickness (IMT), nitrate-mediated dilation (NMD), flow-mediated dilation (FMD), augmentation index (AI), endothelial progenitor cells (EPCs) and other vascular parameters. Subgroup analysis was conducted according to specific types of parameters. Study quality was assessed by using the Newcastle–Ottawa Scale. Sensitivity analysis was conducted to confirm the robustness of the pooled results.
Results:
Fifty-seven studies with 7,312 individuals were included. Twenty-eight studies were considered to be high-quality. ED patients had a 0.11 mm higher IMT (95% confidence interval [CI]: 0.07, 0.15), a 2.86% lower FMD (95% CI: -3.56, -2.17), a 2.34% lower NMD (95% CI: -3.37, -1.31), a 2.83% higher AI (95% CI: 0.02, 5.63), a 1.11 m/s higher PWV (95% CI: 0.01, 2.21), and a 0.72% lower percentage of EPCs (95% CI: -1.19, -0.24) compared to those without ED. However, ABI was similar between ED patients and non-ED individuals. According to sensitivity analysis, the pooled results were robust.
Conclusions
Our study confirmed the associations between ED and several vascular parameters and highlighted the importance of prevention and management of vascular and endothelial dysfunction in ED patients.
