After chemotherapy, adecrease was observed in the left ventricular ejection fraction (LVEF) (Pooled standard mean difference [SMD] = -0.75, 95% CI: -1.18, -0.31, p=0.001, I 2= 95.9%), global longitudinal strain (GLS) (Pooled SMD = -2.38, 95% CI: -3.10, -1.66, p<0.001, I 2= 97.9%), global work index (Pooled SMD = -1.27, 95% CI: -1.68, -0.86, p<0.001, I2= 95.0%), global constructive work (GCW) (Pooled SMD = -1.55, 95% CI: -2.10, -0.99, p<0.001, I 2= 96.9%), and global work efficiency (Pooled SMD = -1.66, 95% CI: -2.39, -0.94, p<0.001, I2= 98.2%). Conversely, global wasted work (GWW) increased (Pooled SMD = 1.17, 95% CI: 0.44, 1.89, p=0.002, I 2= 98.2%). Post-chemotherapy, GCW and GLS were below normal ranges, GWW exceeded normal values, and LVEF remained within normal limits across all subgroups.Conclusions: Echocardiographic MWI provides a non-invasive method for assessing cardiotoxicity induced by anthracyclines, trastuzumab / pertuzumab, or immune checkpoint inhibitors.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733692","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}

A five-fold cross-validation method (training set = 4:1) was employed. A deep residual convolutional neural network (CNN) was trained, and Gradient-weighted Class Activation Mapping (Grad-CAM) was used for visualization. Different ResNet18 models with varying residual blocks (2, 3, 4, 6) were compared to select the optimal model for image classification. Diagnostic decisions were based on a threshold proportion of abnormal images, determined from the training set.Results: A total of 2401 US images from 260 patients (149 gout, 111 control) were analyzed. The model with 3 residual blocks performed best, achieving an AUC of 0.904 (95% CI: 0.887~0.927). Visualization results aligned with radiologist opinions in 2000 images. The diagnostic model attained an accuracy of 91.1% (95% CI: 90.4%~91.8%) on the testing set, with a diagnostic threshold of 0.328.Conclusion: The DL model demonstrated excellent performance in automatically detecting and diagnosing GA in the first MTPJ.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733689","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}

Fewer studies were performed investigating the prognostic relevance using transient elastography (TE), although with promising results. This study was designed to evaluate the prognostic relevance of ARFI elastography.Material and method: Patients receiving ARFI elastography in our ultrasound department between 2010 and 2012 were initially screened for an ARFI examination with a clinical follow-up of at least 5 years. The following events were recorded: liver related death, liver unrelated death, HCC, liver decompensation/ variceal bleeding.Results: A total of 335 patients were included in the final analysis with an ARFI examination of the liver and a follow-up of 60 months. Within the observation interval the number of events with corresponding AUROCs (shown with 95% confidence interval) were: overall death (n=49, 0.76 [0.69 - 0.83]), liver related death (n=25, 0.85 [0.77 - 0.93]), liver unrelated death (n=24, 0.66 [0.55 - 0.77]), HCC (n=15, 0.80 [0.72 - 0.87]), liver related complications/variceal bleeding (n=34, 0.87 [0.82 - 0.93]).
