Summary: Ocular ultrasound is essential for evaluating the eye and orbit, but caution must be taken due to their sensitivity to the thermal and mechanical effects of ultrasound. It is important to use dedicated ocular settings during B-mode imaging, and to adjust settings to reduce acoustic output in Doppler modes to comply with FDA recommendations.

Summary: The induction of pulmonary capillary hemorrhage by lung ultrasound is influenced by physical exposure parameters, physiological conditions, and drug treatment. Xylazine and clonidine tend to increase susceptibility to lung ultrasound-induced PCH, with higher sensitivity in spontaneously hypertensive rats compared to normotensive rats and regardless of mean systemic blood pressure levels.

Summary: Providing care for children with acute illness in limited-resource settings is challenging. In eastern Uganda, a training program in cardiac and lung point-of-care ultrasound (POCUS) for pediatric patients was developed. Evaluation after training showed that trainees were able to perform high-quality ultrasound examinations and accurately interpret images.

Summary: This study evaluated the dependency of pulmonary capillary hemorrhage (PCH) on frames per second (fps), on-screen mechanical index (MIOS), and thermal index (TI) in lung ultrasound imaging. The results showed that PCH increased at low fps, while there was minimal PCH at an MIOS setting of 0.5. Therefore, the study suggests some value for the use of the mechanical index as a predictive indicator of PCH.

Summary: Lung ultrasound has made significant advances in the diagnosis of cardiogenic pulmonary edema. However, the mechanism of vertical artifacts known as B-lines used for diagnosis is still not fully understood. The theory of acoustic trap is useful in understanding the generation of vertical artifacts and differentiating them from lung diseases. The optimal settings of ultrasound machines for generating vertical artifacts have not been established internationally.

Summary: Pulmonary arterial hypertension (PAH) is a rare condition that can lead to right heart failure. Point-of-Care Ultrasonography (POCUS), used at the bedside in real time, has the potential to improve the long-term care of PAH patients in outpatient settings. A study was conducted in two PAH clinics, where patients were randomly assigned to either a POCUS assessment group or a non-POCUS standard care group. The POCUS group received blinded ultrasound assessments and showed significantly more changes in management compared to the control group. Multivariate analysis showed that adding POCUS to physical examination increased the likelihood of management changes. POCUS in PAH clinics is feasible and can support clinical evaluation and decision making.

Summary: This study evaluated the reliability of personal-device-based point-of-care ultrasound devices in obstetrics. The results demonstrated near-perfect agreement and correlation between the estimated fetal weights obtained from these devices and standard ultrasound machines. Therefore, personal-device-based point-of-care ultrasound devices have the potential to increase access to obstetric ultrasound worldwide.

Summary: DNA damage in newborn children's cord blood cells from Mexico City is correlated with the DNA damage in their mothers, as well as the environmental exposure and complications during pregnancy. Mothers living in the southern part of the city have double DNA damage compared to those living in the northern part. This study highlights the importance of antioxidants during pregnancy and the role of the placental barrier in protecting newborns from DNA-damaging effects of pollution.

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.
