The Establishment of a Novel Murine Model of Immune Thrombocytopenia in Pregnancy and the Impacts of Thrombopoietin Receptor Agonist on Platelet Production.

Objective Immune thrombocytopenia (ITP) is frequently associated with pregnancy. However, treatment options for ITP in pregnancy are limited, and there are few animal models available for the establishment of treatments. Here, we aimed to establish a novel murine pregnant model of ITP and to investigate the impacts of thrombopoietin receptor agonist (TPO-RA) on platelet production and reproductive outcomes.

Elevated 12,13-diHOME level in maternal and umbilical cord blood complicated with preeclampsia.

Background: Preeclampsia (PE) is a condition in pregnancy characterized by hypertension and proteinuria, thus leading to severe complications for both mother and fetus, including fetal growth restriction (FGR). However, there are still unclear aspects regarding the pathogenesis, prevention, and treatments. This study aimed to elucidate the characteristics of lipid metabolism in maternal and umbilical cord plasma complicated with PE using liquid chromatography-mass spectrometry (LC-MS).

Successful Management of Uterine Prolapse in Pregnancy: A Case Report of Avoiding a Cervical Laceration by the Reduction of Massive Edema.

We report a case of uterine prolapse in pregnancy, which was successfully managed before delivery. A 35-year-old woman (G2P1) complained consistently of a protruding uterus at 36 weeks gestation, and an engorged uterine cervix without tenderness, urinary disturbance, and incontinence were recognized (Pelvic Organ Prolapse Quantification (POP-Q) score C: +7). Manual retraction of the edematous cervix was gently performed with gauze packing, and strikingly improved edema of the cervix with a POP-Q score of C: -2 was observed one day after the gauze packing.

Spontaneous Pregnancy After the Removal of Long-Term Retained Laminaria.

We report the case of a woman with laminaria retention up to six years, followed by spontaneous pregnancy after the removal by hysteroscope of the intrauterine retained laminaria. A 26-year-old woman (G1P0) visited our hospital with complaints of prolonged menstrual bleeding, dyspareunia, and infertility. She had a history of dilatation and evacuation (D&E) at nine weeks of gestation six years earlier.

The Impact of Assisted Reproductive Technology on Umbilical Cord Insertion: Increased Risk of Velamentous Cord Insertion in Singleton Pregnancies Conceived through ICSI.

: Vasa previa (VP) is a significant perinatal complication that can have serious consequences for the fetus/neonate. Velamentous cord insertion (VCI) is a crucial finding in prenatal placental morphology surveillance as it is indicative of comorbid VP. Assisted reproductive technology (ART) has been identified as a risk factor for VCI, so identifying risk factors for VCI in ART could improve VP recognition.
