Effects of different doses of esketamine intervention on postpartum depressive symptoms in cesarean section women: A randomized, double-blind, controlled clinical study.

Background: The optimal dosage and method of esketamine for postpartum depressive symptoms (PDS) are unclear. We conducted a randomized controlled trial (RCT) to investigate the effect of different doses of esketamine on PDS in women undergoing cesarean section, with evidence of prenatal depression.

Methods: The three groups were high- (2 mg kg) and low-dose (1 mg kg) esketamine via patient controlled intravenous analgesia (PCIA), following an initial intravenous infusion of 0.

Placental micro blood perfusion for isolated single umbilical artery foetuses and VEGF protein expression in the placenta.

Microblood perfusion of isolated single umbilical artery (ISUA) foetus placenta was evaluated using three-dimensional power Doppler ultrasound (3D-PDU). Vascular endothelial growth factor (VEGF) protein expression in the placenta was also semi-quantitative and qualitatively analysed. Differences between ISUA and control groups were compared.

Prenatal diagnosis of double aortic arch with subaortic left brachiocephalic vein and right-side ductus arteriosus using high-definition flow render mode and spatiotemporal image correlation.

Double aortic arch (DAA) with subaortic left brachiocephalic vein (LBCV) and right-side ductus arteriosus (RDA) was not reported before delivery, only in adults with anatomy course findings. We present a case of fetal DAA with subaortic LBCV and RDA using high-definition (HD) flow render mode and spatiotemporal image correlation (STIC).

Prenatal diagnosis of anomalous left brachiocephalic vein courses using high-definition flow render mode and spatiotemporal image correlation.

Background: This study aimed to examine the clinical value of high-definition (HD) flow render mode and spatiotemporal image correlation (STIC) to diagnose anomalous left brachiocephalic vein (LBCV) courses in fetuses.

Methods And Results: Seventeen cases of anomalous LBCV courses were diagnosed using two-dimensional (2D), HD-flow, and HD-flow combined with STIC images and retrospectively analyzed to examine the significance of using HD-flow combined with STIC technology in the diagnosis of anomalous LBCV courses.

Conclusions: HD-flow combined with STIC technology can help in the diagnosis of anomalous fetal LBCV courses, and this technique has important clinical value.

The development and application of a prediction model for postpartum depression: optimizing risk assessment and prevention in the clinic.

Background: Preventive intervention can significantly reduce the human and economic costs of postpartum depression (PPD) compared with treatment post-diagnosis. However, identifying women with a high PPD risk and making a judgement as to the benefits of preventive intervention is a major challenge.

Methods: This is a retrospective study of parturients that underwent a cesarean delivery.

Prenatal diagnosis of complete vascular ring using high-definition flow render mode and spatiotemporal image correlation.

Vascular rings (VRs) are defined as congenital abnormalities of the aortic arch and its branches. VR can form a ring that may compress the esophagus and trachea, which likely result in feeding difficulties and respiratory distress. Physicians performing fetal echocardiography are knowledgeable about VRS and can provide this information to pediatric cardiothoracic surgeons.
