The transverse cerebral fissure of Bichat is a complex anatomic space formed by a median portion (the velum interpositum) and two oblique lateral branches terminating anteriorly at the medial temporal lobes. Its complexity derives from both its embryological development and from its own nature of "virtual anatomic space". Previous imaging studies have addressed the issue of its anatomical description by using pneumoencephalography or transcranial ultrasound and magnetic resonance imaging especially in those cases with expansile lesions into its anatomical borders.

To determine the correlation, precision, mean percentage difference and agreement between cardiac indices (stroke volume [SV], cardiac output [CO], SV index [SVI], and cardiac index [CI]) measured by noninvasive cardiac output monitor (NICOM, Cheetah Medical, Boston, MA, USA) and 2-dimensional transthoracic echocardiography (2D-TTE) across gestations in Chinese pregnant women.

To explore the relationship between maternal glycaemic control and fetal abdominal circumference in pregnancies complicated by T1D.

This study aimed to determine the differences in the cervical load and prevalence of DNA, DNA, DNA DNA, and species DNA between pregnant women with preterm prelabor rupture of membranes (PPROM) with and without a history of cervical excisional treatment. We also assessed the changes in the cervical load and prevalence of DNA, DNA, DNA, DNA, and spp DNA. according to the cone length.

To investigate the interobserver agreement among midwives for the interpretation of intrapartum CTG traces, using both the 2015 FIGO guidelines and the physiology-based guidelines.

maturation (IVM) is an advanced technique and an alternative to conventional fertilization (IVF). It is safe, effective, and cost-effective in patients with polycystic ovary syndrome (PCOS). However, no clinical guidelines state that IVM could work without compromised pregnancy outcomes in patients with PCOS. The purpose of this study was to identify whether previous unstimulated IVM improved the clinical outcomes of women with PCOS in the subsequent IVF cycle.

At present, research has not found easily accessible, accurate, and safe clinical biomarkers that can effectively predict the occurrence of infants born small for gestational age (SGA). The aim of this study is to explore the predictive role of maternal placental growth factor (PIGF) levels on the occurrence of SGA infants.

Previous articles on the relationship between vitamin D and gestational diabetes mellitus (GDM) were inconsistent. Their relationship has been observed primarily through observational studies, and the causality of this association has not been established.

To explore the impacts of different types of physical exercise on health outcomes of individuals with hypertensive disorders of pregnancy (HDPs).

Fetal head malposition can result in neonatal and maternal complications. Fetal head malposition occurs frequently in labor. Appropriate and timely managements are required. Maternal posture and cognitive-behavioral interventions could improve labor outcomes in primigravidas with fetal head malposition.

fetal circulatory characteristics differ from those after birth; the right ventricle assumes more than 60% of the workload in the systemic circulation before birth. The right ventricle automated myocardial performance index (AM+MPI) is a simple, time-efficient, and stable assessment method used to evaluate overall cardiac function. This study aimed to apply the right ventricle AM+MPI technique to explore its role in normal mid-to-late pregnancy fetal cardiac function and compare the AM+MPI differences between diabetic and normal fetuses. A total of 150 pregnant women who visited the obstetric outpatient department at Daxing Hospital, Xi'an, from January 2022 to June 2022 were selected. We excluded 42 patients with comorbid conditions other than diabetes, fetal anomalies, and unclear last menstrual periods, resulting in 85 healthy pregnant patients and 17 diabetic pregnant patients. Using a Samsung WS80A color Doppler ultrasound diagnostic device, we measured the fetal right ventricle AM+MPI, isovolumic contraction time (ICT), isovolumic relaxation time (IRT), and ejection time (ET) in RMPI mode. We performed variability and correlation analyses within the normal group and compared these parameters with those of the diabetic group. In the healthy pregnant group, there was no significant variability in the fetal MPI, ET, or ICT values among the groups ( > 0.05). However, the IRT was positively correlated with gestational age ( < 0.05), with a linear fit formula of IRT = 29.78 + 0.49 × gestational age (DW value 1.87;  = 32.25,  < 0.05), indicating that the IRT increases with gestational age. The right ventricle MPI in the diabetic group was significantly greater than that in the normal group ( < 0.05). The right ventricle AM+MPI technique is simple, time-efficient, and stable and can objectively assess fetal right ventricle function, providing a theoretical basis for the early diagnosis of intrauterine cardiac function abnormalities. Additionally, there are significant differences in the right ventricle MPI between diabetic and normal fetuses, providing evidence for predicting fetal developmental issues and postnatal complications. The right ventricle AM+MPI holds promise as a new method for prenatal evaluation of fetal right heart function.

To determine the rate of clinically significant red blood cell (RBC) antibody seroconversion in pregnancy and associated risk factors and neonatal outcomes.

Congenital right aortic arch (RAA) and double aortic arch (DAA) were difficult to be diagnosed by traditional fetal echography. However, these two diseases have distinct clinical therapies and long-term outcomes which makes the differential diagnosis of great importance. While fetal screening by traditional fetal echography provides limited information about the branches of the aortic arch. This study aimed to discover and evaluate a novel combination of different echocardiography views in the diagnosis and differentiation of RAA and DAA.
