AI Article Synopsis
- The study investigates the effectiveness of using the SMI scoring method alongside the 2017 ACR TI-RADS for distinguishing between benign and malignant thyroid nodules.
- The nodules were categorized into different score groups based on their characteristics and changes in scores were observed to assess diagnostic accuracy.
- Results showed improved specificity, positive predictive value, and overall accuracy after the scoring assignment, indicating enhanced diagnostic capability, although negative predictive value decreased slightly.
Article Abstract
Purpose: To explore the application value of SMI scoring assignment method combined with 2017 American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) in differentiating benign and malignant thyroid nodules.
Methods: According to the 2017 ACR TI-RADS classification, the enrolled nodules were divided into 3 points group, 4 points group, 5 points group, 6 points group and≥7 points group. The nodules were assigned scores according to the echocity of the nodules and the microvessels detected by SMI and their distribution patterns based on ACR TI-RADS. Accompany with the scores increased or decreased after assignment, the thyroid nodules were re-grouped.
Results: The AUC after the scores assignment is better than before (Z = 3.881, P < 0.001). The specificity, positive predictive value and accuracy after score assigned are better than those of before (Z = 8.323, P < 0.001; Z = 8.619, P < 0.001; Z = 5.345, P < 0.001), there is no statistical difference in sensitivity before and after score assigned (Z = -0.513, P = 0.60), and the negative predictive value before assigned score is better than that of after (Z = -3.826, P < 0.001).
Conclusion: The diagnostic efficacy after scoring was better than that of before.

Background: Inequities exist in pediatric surgical outcomes. Differential outcomes have been identified across racial groups, geography, and socioeconomic standing. However, the association between preferred language, interpreter use, and surgical outcomes is not well-studied in pediatric surgical literature.

Bone mineral density (BMD), an important marker of bone health, is regulated by a complex interaction of proteins. Plasma proteomic analyses can contribute to identification of proteins associated with changes in BMD. This may be especially informative in stages of bone accrual and peak BMD achievement (i.

Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).
