Abstract	Hyperreactio luteinalis (HL) is a rare condition that presents as bilateral ovarian enlargement during pregnancy. Typically, it is thought to be caused by increased production of human chorionic gonadotropin (hCG) associated with gestational trophoblastic diseases or multiple pregnancies. The prognosis is relatively good, with many cases resulting in term birth. However, some obstetric complications, such as preeclampsia (PE) and preterm births, have been reported. We present a serious case of HL with subsequent PE that resulted in preterm delivery at 31 weeks of gestation. The soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratio was very high at the onset of PE at 24 weeks of gestation, followed by a modest decline, which then increased in proportion to the exacerbation of symptoms. Since HL cases have also been reported to be associated with PE, repeated measurement of the sFlt-1/PlGF ratio proved useful for better pregnancy management.

Abstract	A uterine artery pseudoaneurysm (UAP) is a life-threatening complication during pregnancy and postpartum. Early diagnosis of exophytic UAP rupture is difficult due to the absence of vaginal bleeding. This study reports the case of a 31-year-old postpartum woman who presented with abdominal pain and fever seven days after vaginal delivery, without symptoms of maternal shock. Ultrasonography revealed a ruptured exophytic UAP with hemoperitoneum, which was confirmed using computed tomography. Interventional radiology confirmed that the site of the pseudoaneurysm was at the level of the uterine artery bifurcation, and embolization was performed immediately after diagnosis using a coil and n-butyl-2-cyanoacrylate. The patient's symptoms were relieved, and she was discharged 12 days after the embolization. At eight months postpartum, the UAP was not visible on transvaginal ultrasonography. Exophytic UAP can occur even in the absence of specific risk factors such as cesarean section or endometriosis, and the UAP may not necessarily rupture immediately after delivery. Obstetricians must remain aware of the possibility of exophytic UAP rupture manifesting as abdominal pain with postpartum fever, rather than as unstable vital signs. This is the first report of an exophytic UAP that occurred at the level of the uterine artery bifurcation. Identification of the sites where exophytic UAP can occur can aid in the early diagnosis of the condition.

Abstract	Aim: Cryoprecipitate (CRYO) is a concentrated preparation of coagulation factors formulated from fresh frozen plasma (FFP), which can replenish coagulation factors rapidly. Preeclampsia (PE) is frequently associated with postpartum hemorrhage (PPH), and the rapid replenishment of coagulation factors is vital in the management. We conducted a retrospective cohort study to determine the efficacy of administering CRYO irrespective of fibrinogen levels in patients with PE who experienced severe PPH. Methods: Patients with PPH accompanied by PE and those who required red blood cell (RBC) transfusion were included. Cases were divided into two groups: those treated with CRYO (N = 16) and those not treated with CRYO (N = 10). The total transfusion volume, blood loss before and after transfusion initiation, duration of hospitalization, presence of pulmonary edema, and performance of either interventional radiology or hysterectomy were compared. Results: The median fibrinogen levels before transfusion were 2.24 and 2.34 g/L in the CRYO group and the not using group, respectively. Although blood loss before transfusion was comparable between the two groups, blood loss after transfusion was significantly less in the CRYO group (median: 520 vs. 2352 mL, p = 0.015), as well as the total blood loss (median: 2285 vs. 3825 mL, p = 0.005) and total transfusion volume (median: RBC 6 vs. 16 U, p = 0.01, FFP 10 vs. 20 U, p = 0.017). Conclusion: Prompt replenishment of coagulation factors using CRYO to patients with PE who experience severe PPH could decrease further bleeding.

Abstract	Objective: Since fetal presentation is an essential factor for planning mode of delivery, the estimation of fetal presentation at delivery is important in prenatal management. This study aimed to clarify the transition of fetal presentation during pregnancy and to propose practical strategy to predict final fetal presentation. Methods: During the period of 2 years, fetal presentations were analyzed using ultrasonography during the prenatal visits at and after 22 weeks of gestation in a single facility. The relationship between the transition of fetal presentation and final presentation at delivery was analyzed. Further, a prediction model was developed to predict the final fetal presentation at birth. Results: Among 1737 singleton pregnancies with full-term delivery, non-cephalic delivery occurred in 76 pregnancies (4.4%). Non-cephalic presentation in later half of the gestational period was associated with low incidence of spontaneous cephalic version. Furthermore, we found that in 46% of women with a final non-cephalic delivery, the non-cephalic presentation continued during whole of the observational period without spontaneous cephalic version. Based on the analyzed data of this cohort, we show that in a group of women with non-cephalic presentation at 35/36 weeks, the best predictability for spontaneous cephalic version depended on whether the cephalic presentation was observed at least once at and after 30 weeks of gestation. Conclusion: Our findings suggest that information on the changes in fetal presentation during gestation contributes to the prediction of the fetal presentation at delivery and planning mode of delivery.

Abstract	Imaging and histological changes occurring in adenomyosis due to pregnancy are unclear. A 38-year-old nulliparous woman presented with dysmenorrhea and infertility. Pelvic magnetic resonance imaging (MRI) showed diffuse-type adenomyosis. Following pregnancy by in vitro fertilization, she was hospitalized at 23 weeks of gestation due to fetal growth restriction and subsequently diagnosed with preeclampsia. A second MRI performed due to an elevated inflammatory response at 31 weeks of gestation detected no obvious degenerative findings. An emergency cesarean section was performed at 33 weeks of gestation because of nonreassuring fetal status. On postpartum day 2, she showed uterine tenderness with a dramatically elevated inflammatory response. A third MRI showed cyst-like degenerations with hemorrhagic changes without abscess. By postpartum day 7, she was quickly relieved and discharged from the hospital. A fourth MRI at postpartum month 4 confirmed the disappearance of degenerations. This is the first report of imaging findings of early postpartum degeneration of adenomyosis.

Abstract	Background: Adenomyosis is associated with unfavorable perinatal outcomes; however, the effect of an adenomyomectomy on pregnancy outcomes remains unclear. Pregnancy following an adenomyomectomy has been reported to be associated with a high risk for uterine rupture; however, the actual incidence remains unknown. Objective: This study aimed to evaluate the effect of an adenomyomectomy on pregnancy outcomes by retrospectively comparing the pregnancy outcomes of women who underwent an adenomyomectomy with those of women with adenomyosis. Study design: This was a single-center retrospective study in which the pregnancy outcomes of women who underwent an adenomyomectomy and for whom complete resection of the affected tissue under laparotomy was achieved were compared with those of women with adenomyosis. The following pregnancy outcomes were examined: second-trimester miscarriage, preterm prelabor rupture of membranes, preterm delivery, spontaneous preterm delivery, preeclampsia, rate of cesarean delivery, blood loss during cesarean delivery, incidence of placenta accreta spectrum, neonatal body weight, and small for gestational age infants. Results: A total of 18 pregnant women who underwent an adenomyomectomy and 105 pregnant women with adenomyosis were included in this study. All women who underwent an adenomyomectomy delivered via cesarean delivery, and among them, 1 had a uterine rupture at 30 weeks of gestation. Although there was no significant difference between pregnant women who underwent an adenomyomectomy and those with adenomyosis in the incidence of second-trimester miscarriage (0% [0/18] vs 7.6% [8/105], respectively; Conclusion: Uterine rupture following an adenomyomectomy may occur because of the high incidence of placenta accreta spectrum. However, an adenomyomectomy may reduce adverse pregnancy outcomes associated with adenomyosis, such as preterm prelabor rupture of membranes, preeclampsia, and small for gestational age infants. An adenomyomectomy may be a viable option for women among whom the procedure is inevitable before conception.

Abstract	Objectives: Adenomyosis is associated with unfavorable perinatal outcomes, and recent case reports show that some women with adenomyosis experience pain at the adenomyosis lesion during pregnancy and have detrimental perinatal outcomes. This study aimed to clarify the clinical characteristics of this pain and perinatal outcomes associated with this phenomenon. Methods: This was a single-center retrospective analysis of pregnant women with adenomyosis. The incidence of pain onset at adenomyosis lesions, defined as persistent pain at the adenomyosis site with administration of analgesics for pain relief, and its association with perinatal outcomes were analyzed. Results: Among 91 singleton pregnancies with adenomyosis, 12 pregnancies (13.2 %) presented with pain. One pregnancy resulted in second-trimester miscarriage, and 5 of the 11 pregnancies (45 %) developed preeclampsia, which resulted in preterm delivery, and 3 of the 12 pregnancies (25 %) achieved term delivery. The incidence of preeclampsia and preterm delivery was higher in those who experienced pain than in those without (45 % [5/11] vs. 15 % [11/74]; p<0.05, and 73 % [8/11] vs. 34 % [25/74]; p<0.05, respectively). Among women with pain, the maximum C-reactive protein level was significantly higher in women who developed preeclampsia than in those who did not (5.45 vs. 0.12 mg/dL, p<0.05). Conclusions: Our study revealed that adenomyosis can cause pain in over one of eight pregnancies with adenomyosis, which may be associated with the increased incidence of preeclampsia resulting in preterm delivery. Women with pain, especially those with high C-reactive protein levels, may be at high risk for future development of preeclampsia and consequent preterm delivery.

Abstract	The response of autotaxin (ATX)-lysophosphatidic acid (LPA) signaling system to placental oxidative stress (OS) and its significance to preeclampsia were investigated. For this purpose, oxidative stress index (OSI) and ATX levels were measured in the serum of pregnant women with preeclampsia. The expression levels of ATX and LPA receptors were assessed in trophoblast cells under high OS and glucose deprivation/re-oxygenation (OGD/R) conditions, with particular emphasis on the antioxidative nuclear factor erythroid 2-related factor 2 (NRF2) pathway. The influence of ATX-LPA signaling on cell migration was also evaluated using the wound healing assay. ATX concentrations and OSI in the serum were found to be elevated in preeclamptic women. The serum ATX levels were also positively correlated with OSI. Trophoblast cells responded to OS by increasing ATX mRNA expression concomitantly with intranuclear translocation of Nrf2, whereas inhibition of Nrf2 activation reverted this effect. The ATX-LPA signaling pathway facilitated trophoblast cell motility after Nrf2 activation. In conclusion, OS accumulation in preeclamptic placenta may activate the ATX-LPA system in trophoblasts via the Nrf2 pathway to sustain trophoblast functionality.

Abstract	Objectives: Although adenomyosis is reportedly associated with adverse pregnancy outcomes, clinical factors related to the high risk of obstetric complications are unclear. This study aimed to elucidate the characteristics of adenomyosis lesions associated with the increased incidence of obstetric complications based on imaging findings. Methods: This was a retrospective, observational cohort study conducted in a tertiary perinatal care center. Eighty-eight singleton pregnant women with adenomyosis were included in the study. Based on magnetic resonance imaging or ultrasonography before and/or during pregnancy, patients were classified according to three types of image characteristics: the extent of adenomyosis lesion (focal type or diffuse type), location of the lesion (extrinsic type, intrinsic type, or indeterminate type), the positional relationship between the lesion and the placenta (placenta distant from adenomyosis or placenta over adenomyosis), and the incidence of obstetric complications were examined. Results: Patients with diffuse type adenomyosis are significantly more likely to have spontaneous second-trimester miscarriage (diffuse type vs. focal type: 16.7 vs. 0%, Conclusions: We demonstrated that the frequency of obstetric complications related to adenomyosis varies depending on the extent and location of the lesion; patients with diffuse type adenomyosis have an increased risk of spontaneous second-trimester miscarriage, preterm premature rupture of membranes, and preeclampsia, while patients with extrinsic type adenomyosis have an increased risk of placental malposition. Imaging evaluation of adenomyosis prior to conception or early in pregnancy may be useful for the obstetrical risk assessment among patients with adenomyosis.

Abstract	Aim: We aimed to investigate the associations of endometriosis and adenomyosis with pregnancy complications by using a large-scale Japanese database. Methods: We retrospectively analyzed 145 590 singleton pregnancies from the Japan Perinatal Registry Network Database. Pregnant women registered as having endometriosis or adenomyosis were designated as the case group (EA), whereas the control group (non-EA) was selected using propensity-score matching adjusted for variables such as age, parity, BMI, smoking history, and the use of assisted reproductive technology. The main outcomes included placental malposition, preterm birth, and hypertensive disorders of pregnancy (HDP). Results: In total, 1203 patients from both the EA and non-EA groups were matched and evaluated. The EA group showed significantly higher rates of placenta previa (odds ratio [OR], 3.01; 95% confidence interval [CI], 1.84-4.92), low-lying placenta (OR, 2.02; 95% CI, 1.06-3.86), and preterm birth (OR, 1.44; 95% CI, 1.13-1.84) than the non-EA group. However, no significant difference was observed in the incidence of HDP (OR, 1.22; 95% CI, 0.90-1.66). Conclusion: The use of propensity-score matching to analyze a nationwide perinatal database in Japan clarified that EA was associated with increased pregnancy complications, specifically placental malposition, including placenta previa and low-lying placenta, and preterm birth, but not with HDP.
