Summary: Recent studies have found correlations between kinetic energy and viscous dissipation rate in the left ventricle with heart health. While 4D-flow imaging or computational fluid dynamics can provide rich data, they are difficult to acquire clinically. Color Doppler echocardiography, on the other hand, is more commonly used clinically but has limitations in measuring blood flow velocity components.

Summary: This study proposes a 40-MHz high-frequency ultrasound (HFUS) imaging system for dynamic wall shear stress (WSS) estimation based on mouse carotid artery blood flow velocity gradient measurements. The method was tested on mice, and differences in time-averaged and oscillatory WSS were observed, which correlated with plaque formation. The proposed HFUS WSS imaging method is useful for investigating the WSS effect on atherosclerotic plaque development.

Summary: A detailed study of fetal growth indices and umbilical artery flow rates in Murciano-Granadina goats has been performed using ultrasonography. The measurements were taken from 18 to 125 days post-breeding, and both fetal growth indices and blood flow parameters showed significant changes throughout the pregnancy period.

Summary: Doppler ultrasound can be used to indirectly assess the effect of increased intrarenal pressure on renal blood flow during retrograde intrarenal surgery (RIRS). By analyzing the vascular flow spectra from selected blood vessels in the kidney, it is possible to determine Doppler parameters that reflect the renal perfusion status, indicating the degree of vasoconstriction and reflecting the resistance of kidney tissue.

Summary: Early detection of gestation is crucial in cattle farming for economic and management purposes. Due to the inefficiency of oestrous detection, it is important to identify non-pregnant cows as early as possible. Direct and indirect diagnostic methods have been developed to improve reproductive performance.

Summary: This study observed the morphological characteristics of patent foramen ovale (PFO) using transesophageal echocardiography (TEE) and analyzed its correlation with right-to-left shunt (RLS) using contrast-transthoracic echocardiography (c-TTE) and contrast-transcranial Doppler ultrasonography (c-TCD). The results showed that the morphological structure of PFO is an influencing factor of RLS, and TEE can observe the specific morphological characteristics of PFO, which can further predict the level of RLS and help predict the occurrence of Cryptogenic stroke (CS).

Summary: The frequency of semen collection is an important factor affecting the performance of rams in breeding centers. Ultrasound technology can be used to evaluate and predict changes in sperm quality. The study found that increasing the frequency of semen collection led to an increase in testicular echotexture and doppler parameters. Sperm motility and functionality decreased with increased frequency, indicating the impact of collection frequency on sperm quality. Ultrasound technology can be used as a predictive tool for assessing the effects of semen collection frequency on sperm quality in donor rams.

Summary: This study found that high-frequency and ultra-high frequency ultrasound can accurately diagnose and evaluate the features of onychopapilloma. Ultrasound examinations can show hypoechoic bands in the nail bed, abnormalities in the nail plate, and irregularities in other structures, which correlate with histological characteristics. In addition, ultrasound examinations can also detect recurrence after surgery.

Summary: This study evaluates the additional value of superb microvascular imaging (SMI) in characterizing focal liver lesions (FLLs). The combination of B-mode ultrasound and SMI improves the characterization of FLLs, especially in diagnosing malignant tumors and hemangiomas. SMI provides higher sensitivity than CDI and PDI in detecting tumor vascularity.

Summary: Distributed lag models (DLMs) are used to estimate lagged associations and identify critical exposure windows. A simulation study on prenatal NO2 exposure and birth weight revealed that bias amplification and variance inflation can occur in certain combinations of DLM estimation approaches and time-trend adjustment methods with low-spatial-resolution exposures and extended lags. The spatial resolution of exposure data and the parameterizations of the time trend adjustment and lag constraints should be jointly considered in DLM analyses.

Summary: Preeclampsia is a hypertensive disorder of pregnancy caused by abnormal placentation. Fructose, which plays a critical role in fetal growth, is produced in the placenta during early pregnancy to assist fetal survival in a hypoxic environment. Impaired placentation leads to excessive fructose production, which drives various pathological features of preeclampsia. In addition, dietary fructose intake has been identified as an independent risk factor for preeclampsia.

Summary: The study found that higher ambient temperatures are associated with impaired fetal growth. Specifically, temperature during early to mid-pregnancy has the strongest impact on head parameters, while temperature during late pregnancy has the strongest impact on abdominal circumference. This finding is important for understanding the implications of climate change on fetal health.

Summary: Adverse birth outcomes can lead to mortality, morbidity, and childhood developmental challenges. The United States has significant racial and socioeconomic disparities in these outcomes, requiring effective interventions for low-income pregnant individuals. Expanding home visiting programs, specifically the Nurse-Family Partnership program, is recommended to improve newborn and maternal outcomes. This study aims to determine the effects of intensive nurse home visiting programs on crucial birth outcome indicators.

Summary: Prenatal exposure to personal care products may be associated with adverse birth outcomes such as preterm birth and low birth weight. Hair product use, nail polish use, and certain personal care products were found to have associations with birth weight and birth length. These findings can inform future interventions and clinical recommendations to reduce exposures linked to adverse pregnancy outcomes.

Summary: This study aimed to investigate the differences in T cell phenotype and function in uterine intervillous blood (IVB) between normal pregnancy and preeclampsia, and to explore the immunologic basis of preeclampsia. The results showed that preeclampsia was associated with a greater pro-inflammatory cytokine ratio in uterine IVB T cell subsets, indicating an inflammation-related mechanism of preeclampsia. Therefore, IVB sampling is a useful tool for studying human uterine T cell biology and may provide insights for immunotherapeutic strategies for preeclampsia.

Summary: This study evaluated the association between antepartum depressive symptoms and significant postpartum opioid use during birth hospitalization. It found that antepartum depressive symptoms were associated with significant postpartum inpatient opioid use, especially following cesarean delivery. Further investigation is needed to determine whether identifying and treating depressive symptoms in pregnancy may impact the pain experience and opioid use postpartum.
