Univariate analysis and binary logistic regression analysis of the influencing factors were conducted to identify LAMN and ASA. The AUROC was calculated to analyze the diagnostic efficacy of these independent factors. A four-grid table was established to determine the diagnostic efficacy of the ultrasound marks for diagnosing LAMN.Results: Patient age and appendix short diameter in the LAMN group were found to be significantly higher than those in the ASA group. The neutrophil ratio and thickness of the appendix wall in the LAMN group were significantly lower than they were in the ASA group. Patient age (OR=1.112, p=0.015) and appendix short diameter (OR=1.476, p=0.008) were independent risk factors for LAMN. The AUROCs for age and short diameter were 0.898 [95% CI: 0.807, 0.956] and 0.953 [95% CI: 0.879, 0.988], respectively. The LAMN group tumors were characterized by the appearance of an \"onion skin\" sign or a purely cystic mark on sonograms, with specificities of 100% for both. Neutrophil ratio (OR<0.001, p=0.064) and thickness of the appendix wall (OR=0.776, p=0.414) were not independent risk factors for ASA.Conclusion: Employing ultrasonography with clinical features is useful for distinguishing LAMN from ASA. Patient age, short diameter of the appendix, and sonographic appearance of \"onion skin\" or purely cystic mark could be key factors in diagnosing LAMN.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"348-355"},"PeriodicalIF":0.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrast enhanced ultrasound (CEUS) allows to visualize blood flow and tissue perfusion. CEUS has proven to be safe without risk of nephrotoxicity. The availability of a contrast agent (tracer) for ultrasound imaging allows for the first time a dynamic assessment of tissue perfusion (blood flow and wash-in/wash-out pattern) which is an essential part for the detection and characterisation of pathological tissue and abnormal organ function. It was an outstanding achievement of academic centers in close cooperation with EFSUMB to investigate and validate the clinical potential of this new technology for the diagnosis and monitoring of various diseases and to develop clinical guidelines based on an in-depth assessment of the existing scientific publications. An important part of the implementation of CEUS in clinical practice was the development of contrast-specific imaging modes on the ultrasound scanners (in close cooperation with the machine manufacturers), the optimization of the machine setups for contrast imaging and the education provided to clinical users in form of workshops, webinars, textbooks and scientific congresses.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"405-416"},"PeriodicalIF":0.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141160128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Venous ultrasound assessments were conducted to determine the VExUS score. Cox regressionanalysis was used to identify predictors of 6-month mortality.Results: The study found no significant association between the VExUS score and 6-month mortality in AKI patients in the regression analyses. However, in the subgroup analyses, VExUS grades 2-3 were associated with lower survival rates in the cardiorenal subgroup (HR: 3.98 [95% CI: 1.33-11.93]), and in AKI grade 1 (HR: 4.07 [95% CI: 1.74-9.49]). This association was not present in other AKI subgroups. The predictors of mortality included higher age (OR: 1.024; 95% CI 1.005-1.043), malignancy (OR: 2.186; 95% CI 1.408-3.392), lower systolic blood pressure (OR: 0.990; 95% CI 0.982-0.998), elevated pulse (OR: 1.013; 95% CI 1.005-1.022), and higher lactate levels (OR: 1.210; 95% CI 1.097-1.334).Conclusion: The VExUS score did not predict 6-month mortality in the general cohort of AKI patients in the emergency department.
