Effect of an emergency/planned cesarean section on the perinatal outcomes of pregnant women with placenta accreta spectrum and their neonates: a retrospective study cohort.

Background: Placenta accreta spectrum (PAS) is an obstetric condition. This study analyzes the outcomes of PAS parturients and their newborns undergoing emergency cesarean sections as opposed to planned cesarean sections.

Methods: In this research, we conduct a thorough retrospective analysis of 345 patients with placenta accreta at a single medical center.

Placental chorioangiomatosis: a case report and literature review.

The placenta is a highly specialized temporary organ during pregnancy. As the hinge of material exchange between mother and fetus, it plays a crucial role in maintaining the fetus's intrauterine life and growth period of fetus. Placental lesions or dysfunction can cause pregnancy diseases.

The role of MRI in "estimating" intraoperative bleeding during cesarean section for placenta accreta: A prospective cohort study.

Objectives: The prenatal detection of placenta accreta spectrum (PAS) disorder is crucial for treatment strategy formulation. MRI descriptors may offer a more objective method for predicting PAS and clinical outcomes. The aim of this study is to investigate the predictive value of MRI examination for intraoperative blood loss in PAS cesarean section and elucidating the MRI descriptors that are more valuable for predicting intraoperative blood loss.

Epidemic history investigation: a new method of finding close contacts.

Introduction: Coronavirus disease 2019 has become a major global public health concern in December 2019. However, finding and excluding close contacts of COVID-19 infectors is a critical but difficult issue. This study aimed to introduce a new method of epidemiological investigation named space-time companions, which was adopted in Chengdu, China, in November 2021.

Umbilical artery thrombosis and maternal positive autoimmune antibodies: two case reports and a literature review.

Background: Previous studies have shown that abnormal increases in autoimmune antibodies in pregnant women may increase the risk of maternal thrombosis. However, at our hospital, two pregnant women presented with umbilical artery thrombosis and positive maternal autoantibodies were detected in both, which led us to consider whether maternal autoantibodies also played a role in umbilical artery thrombosis.

Case Presentation: Case 1: Fetal ultrasound of a 34-year-old pregnant woman at 30 weeks gestation showed two umbilical arteries, with an inner diameter of approximately 0.

Mediation effect of pregnancy-induced hypertension on the association between assisted reproductive technology and adverse neonatal outcomes: a population-based study.

Background: Assisted reproductive technology (ART) has been widely used in the treatment of infertility, and is associated with adverse maternal and neonatal outcomes. However, the potential pathways by which ART affects adverse neonatal outcomes are unclear. We aimed to investigate the role of pregnancy-induced hypertension (PIH) in the association between ART and adverse neonatal outcomes.

Novel organoid construction strategy for non-involuting congenital hemangioma for drug validation.

Background: Non-involuting congenital hemangiomas (NICHs) are fully formed vascular tumors at birth with distinctive clinical, radiologic, and histopathological profiles. In the literature, there is no effective therapy strategy for patients with NICH except surgery. Currently, no cell line or animal model exists for studying the mechanism of NICH and drug validation.

HELLP syndrome manifesting as abnormal fetal umbilical artery blood flow and rapidly worsening laboratory indexes: A case report.

Rationale: HELLP syndrome, a rare but serious obstetric complication, is often overdiagnosed due to its nonspecific symptoms and inappropriate clinical testing.

Patient Concerns: A 30-year-old nulliparous pregnant Chinese woman at gestational age of 28+1 weeks was admitted to our hospital because Doppler ultrasonography at a local hospital had detected loss of fetal umbilical artery end-diastolic blood flow lasting 12 hours. On admission to our hospital, the patient showed elevated blood pressure (148/84 mm Hg), but blood pressure and laboratory indicators after admission were normal.

Potential resolution of placenta previa from the 28th-to the 36th-week of pregnancy: A retrospective longitudinal cohort study.

Introduction: Placenta previa greatly contributes to severe antenatal and post-partum hemorrhage. Previous studies have mainly focused on the risk factors of placenta previa, with very few studies reporting which factors may affect the potential resolution of 28th-week previa. This study aimed to investigate the impact of maternal characteristics on potential resolution of placenta previa from the 28th-to the 36th-week of pregnancy.
