Summary: This study monitored plaque composition in subclinical carotid stenosis patients over a 12-month period, showing that most patients on low-medium dosage statin therapy had stable or increased plaque echogenicity. While oral supplementation of vitamin K2 did not significantly change plaque composition overall, it did enhance GSM values decline for patients with reduction in GSM values.

Summary: This study aimed to identify factors influencing pulsatility (PI) and resistance (RI) indices measured in patients with carotid atherosclerosis using TCCS. The study found that age, arterial hypertension, diabetes mellitus, carotid plaque width, and male gender were independent predictors of increased cerebral arterial resistance and/or pulsatility.

Summary: Arterial stiffness, echolucency, and texture features are altered in hypertension and associated with increased cardiovascular disease risk. This study found that increased arterial stiffness in hypertension is mainly due to the non-linear mechanics of higher blood pressure, not structural changes in the artery wall. In addition, high load-dependent stiffness is associated with a more homogenous carotid artery wall texture, potentially related to subclinical atherosclerosis and future cardiovascular disease development.

Summary: This study analyzed the association between cardiovascular health scores and carotid artery plaques and compared the predictive capacity of different scoring methods. The new LE8 score showed inverse and dose-response associations with carotid plaques, particularly bilateral plaques. The conventional LS7 score performed similarly in predicting carotid plaques, especially when scored as 0-14 points.

Summary: This study investigated the contribution of modifiable and non-modifiable cardiovascular risk factors to vulnerable plaque morphology. The results showed positive associations between male sex, obesity, high fasting glucose levels, and low-density lipoprotein dyslipidemia with lower low GSM index. On the other hand, the use of glucose-lowering medication was associated with a more stable plaque phenotype. The study highlighted the importance of glycemic and lipid metabolism in the development of vulnerable carotid plaques.

Summary: This study found that measuring carotid intima thickness and other areas' intima thickness can help differentiate patients with large-artery atherosclerosis stroke from normal control subjects. The relevant intima thickness is associated with traditional atherosclerotic risk factors and can provide additional diagnostic value.

Summary: The study aimed to use an adaptive Bayesian regularized Lagrangian carotid strain imaging (ABR-LCSI) algorithm to monitor atherogenesis in a murine model and examine the association between ultrasound strain measures and histology. The results showed that ABR-LCSI can be used to measure arterial wall strain in mice and that changes in strain are associated with changes in arterial wall structure and plaque formation.

Summary: The study aimed to investigate whether carotid strain and strain rate can predict major cardiovascular events in patients with metabolic syndrome over a 3-year period. The results showed that carotid strain and strain rate were independent predictors of major cardiovascular events in these patients, indicating their potential value as early prognostic indicators for cardiovascular risk.

Summary: This study aimed to investigate the contribution of subtotal ultrasound-guided percutaneous microwave ablation (MWA) to the inhibition of programmed cell death protein-1 (PD-1) in advanced hepatocellular carcinoma (HCC). The results showed that MWA >50% AR could enhance immune-related gene expression, activate CD8+ T cells, and thereby boost the immunomodulatory effect of PD-1 inhibitors.

Summary: Researchers investigated whether quantitative ultrasound assessment of hyoid bone movement during induced swallowing would predict the failure of traditional assessment methods in stroke patients. They found that manual ultrasound measurement was not accurate in predicting the assessment outcome, but a machine learning algorithm showed substantial agreement with the results, suggesting its potential for improving dysphagia assessment.

Summary: This study proposes a straightforward simulation approach based on superposed Wave (s-Wave) to accelerate photoacoustic simulation. By manipulating the phase and amplitude of sensor data, the computation time is significantly reduced. The results show that s-Wave exhibits a speed improvement >2000 times compared with k-Wave in a sparse system configuration, and in terms of optimization-based image reconstruction, the reconstruction time is reduced by approximately 50 times.

Summary: This study introduces a fully automated, real-time method for measuring left atrial volume in echocardiography using a neural network to identify key time points and segmentation techniques. The results show that this method provides comparable accuracy to manual measurements while saving time and reducing operator variability, with an average volume difference of 2.9 mL for 2-D and 7.8 mL for 3-D imaging. The application of pseudo-labeling improves the stability of volume curves and the accuracy of end-systole measurement.

Summary: A new protocol for fabricating a microflow phantom with bifurcated geometry at a superficial region was proposed in this study. Ultrasound imaging confirmed the successful creation of the desired flow tract with bifurcation at a depth of 2-5 mm. The experiments demonstrated the validity of the proposed protocol for creating a microscale intricate flow tract with desired dimensions and depth. This new phantom will facilitate further improvement in ultrasound technologies for precise visualization of superficial complex vasculatures.
