The noninvasive myocardial work technique, which incorporates left ventricular afterload, represents a new method for assessing left ventricular functional.Aim: The aim of this study is to explore the value of noninvasive myocardial work technique in assessing left ventricular systolic function in patients with PVCs.Methods: Compare the clinical data, two-dimensional echocardiography parameters, and myocardial work parameters of 66 patients with PVCs and 35 healthy volunteers and explore the relevant risk factors for postoperative recurrence in patients with PVCs.Results: In patients with PVCs compared to the control group, they exhibit enlargement of left atrial diameter (LAD) and left ventricular internal dimension in diastole (LVIDd), as well as thickening of the left ventricular wall. The global work waste (GWW) increases, while the global work efficiency (GWE) decreases. There is a significant negative correlation between the PVC burden and GWE (r = -0.70, p <0.01), and a significant positive correlation between the PVC burden and GWW (r = 0.58, p <0.01). GWE is a sensitive indicator for predicting the recurrence of PVCs after radiofrequency ablation. Patients with GWE <91.5%, global longitudinal strain (GLS) <15.5%, and ejection fraction (EF) <62.5% have a higher postoperative recurrence rate.Conclusion: PVCs can cause impairment of left ventricular systolic function.

Ultrasound examination was performed using both transvaginal and transabdominal routes. UM vascularization pattern was assessed by power Doppler (PD) and SMI, while elastographic pattern was assessed by shear wave (SWE) and strain (STE).

The mean age was found to be 12.80 ± 3.67 years, with 30% female and 70% male. The patients were histopathologically divided into two groups: simple appendicitis (Group 1, 41 patients, 82%) and complicated appendicitis (Group 2, 9 patients, 18%). CRP (C-reactive protein) levels (p = 0.004) and periappendiceal fatty tissue thickness (PFI) (p < 0.005) were found to be statistically significantly higher in Group 2 compared to Group 1.

This study addresses the global rise in PTMC incidence and the challenges in treatment decision-making with high-resolution ultrasonography.Method: This study enrolled 1638 patients with clinically staged cN0 PTMC who received surgical treatment from 1997 to 2019 at Beijing Friendship Hospital. Deep learning model was developed using fully connected neural network. Feature selection included 1000 iterations of Bootstrap sampling and Recursive Feature Elimination (RFE) to identify the top 10 features. Data preprocessing involved normalization and imputation for missing values. SMOTE addressed class imbalance. The model was trained and tested on random data split, with performance metrics including Accuracy (ACC), Area Under the Curve (AUC), Sensitivity (SEN), and Specificity (SPE), visualized through a ROC curve and confusion matrix.Results: The fully connected deep neural network model demonstrated high accuracy (ACC 0.81), Area Under the Curve (AUC 0.74), sensitivity (SEN 0.65), and specificity (SPE 0.83) and visualized by ROC curve and confusion matrix. These results highlight the model's reliability and potential as an effective tool in predicting postoperative complications and assisting in clinical decision-making for PTMC patients.Conclusion: This study highlights the potential of deep learning in enhancing medical predictions and personalized healthcare. Despite promising results, limitations include a single-center data source and unconsidered factors like lifestyle and genetics. Future research should expand data sources, include more influencing factors, and refine algorithms to improve accuracy and applicability in thyroid cancer treatment.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142072966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
