Abstract
Purpose The Japan Society of Obstetrics and Gynecology (JSOG) registry gathers comprehensive data from registered assisted reproductive technology (ART) facilities in Japan. Herein, we report 2021 ART cycle characteristics and outcomes. Methods Descriptive statistics were used to summarize and analyze 2021 data. Results In 2021, 625 ART facilities participated in the registry; 27 facilities did not conduct ART cycles and 598 registered treatment cycles. In total, 498 140 cycles were registered, and there were 69 797 neonates (increases of 10.7% and 15.5%, respectively, from the previous year). The number of freeze-all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles decreased in 2021; the number of neonates born was 2268 for IVF-embryo transfer (ET) cycles and 2850 for ICSI cycles. Frozen-thawed ET (FET) cycles increased markedly from 2020 (11.2% increase). In 2021, 239 428 FET cycles were conducted, resulting in 87 174 pregnancies and 64 679 neonates. For fresh transfers, the total single ET, singleton pregnancy rate, and singleton live birth rates were 82.7%, 97.0%, and 97.3%; for FET, these rates were 84.9%, 96.9%, and 97.1%. Conclusions The 2021 Japanese ART registry analysis showed marked increases in both total treatment cycles and live births from the previous year.

Abstract
This study aimed to elucidate the etiologies of and risk factors for recurrent pregnancy loss (RPL) according to fertile ability, focusing on the differences between superfertile and subfertile patients. This retrospective observational study included 828 women with RPL between July 2017 and February 2020. Patients were divided into three groups based on time to pregnancy (TTP): superfertile (SUP) (TTP ≤3 months for all previous pregnancies), subfertile (SUB) (previous TTP ≥12 months and use of assisted reproductive technology [ART]), and Normal (N) (TTP >3 or <12 months without ART). All patients were assessed for uterine anatomy, antiphospholipid antibodies (APAs), thyroid function, and thrombophilia. Of the 828 patients, 22%, 44%, and 34% were assigned to the SUP, SUB, and N groups, respectively. The mean ages were 33.9, 38.2, and 35.9 years in the SUP, SUB, and N groups, respectively, revealing a significant difference (P < 0.001). The anti-CL β2GPI antibody positivity rate was significantly higher in the SUP group (4.6%) than in the N group (0.8%; P = 0.016). The prevalence of APA positivity was lowest in the N group. Overall, the clinical characteristics and etiologies of RPL associated with superfertility and subfertility were strikingly similar, with comparable positivity rates after adjusting for maternal age. Further investigation including chromosomal analysis of products of conception is needed to elucidate the clinical impact of differences in fertility on patients with RPL.

Abstract
Preterm birth (PTB) is the leading cause of neonatal mortality, and reducing the PTB rate is one of the most critical issues in perinatal medicine. Cervical insufficiency (CI), a major cause of PTB, is characterised by premature cervical ripening in the second trimester, followed by recurrent pregnancy loss. Although multiple clinical trials have suggested that progesterone inhibits cervical ripening, no studies have focused on progesterone-induced molecular signalling in CI. Here, we established a primary culture system for human uterine cervical fibroblasts using a sample of patients with refractory innate CI who underwent transabdominal cervical cerclage and patients with low Bishop scores who underwent elective caesarean section as controls. RNA sequencing showed that the progesterone response observed in the control group was impaired in the CI group. This was consistent with the finding that progesterone receptor expression was markedly downregulated in CI. Furthermore, the inhibitory effect of progesterone on lipopolysaccharide-induced inflammatory stimuli was also impaired in CI. These results suggest that abnormal cervical ripening in CI is caused by the downregulation of progesterone signalling at the receptor level, and provide a novel insight into the molecular mechanism of PTB.

Abstract
Antiphospholipid syndrome (APS) is an established cause of recurrent pregnancy loss (RPL). It is necessary to detect persistently positive antiphospholipid antibodies to diagnose APS. This study aimed to explore risk factors for persistent anticardiolipin (aCL) positivity. Women with a history of RPL or with a history of one or more intrauterine fetal deaths after 10 weeks underwent examinations to determine the causes of RPL, including antiphospholipid antibodies. If aCL-IgG or aCL-IgM antibodies were positive, retests were performed at least 12 weeks apart. Risk factors for persistent aCL antibody positivity were retrospectively investigated. The number and percentage of cases above the 99th percentile were 74/2399 (3.1%) for aCL-IgG, and 81/2399 (3.5%) for aCL-IgM. Of the initially tested cases, 2.3% (56/2399) for aCL-IgG and 2.0% (46/2289) for aCL-IgM were ultimately positive above the 99th percentile in retests. Retest values after 12 weeks were significantly lower than the initial values for both IgG and IgM immunoglobulin classes. Initial aCL antibody titers were significantly higher in the persistent-positive group than in the transient-positive group for both IgG and IgM immunoglobulin classes. The cut-off values for predicting persistent positivity of aCL-IgG antibodies and aCL-IgM antibodies were 15 U/mL (99.1 percentile) and 11 U/mL (99.2 percentile), respectively. The only risk factor for persistently positive aCL antibodies is a high antibody titer during the initial test. When the aCL antibody titer in the initial test exceeds the cut-off value, therapeutic strategies can be defined in subsequent pregnancies without waiting for 12 weeks.

Abstract
When a woman presents with an acute abdomen with cystic lesions in the abdominal cavity, the differential diagnosis includes torsion or rupture of an ovarian tumor. We report our experience with a 54-year-old nulliparous woman who underwent emergency surgery for a suspected ruptured ovarian tumor. Intraoperative examination revealed disruption of a cystic tumor that had developed externally from the fundus of the uterus. The patient, who was taking aspirin because of a history of medullary infarction, reported lower abdominal discomfort for several days. When she sought care, she was referred to the gynecology department where transvaginal ultrasonography and contrast-enhanced computed tomography showed a poorly toned mass with a maximum diameter of 20 cm posterior to the uterus. She also had a large amount of ascites reaching around the liver and the spleen. She underwent an emergency laparotomy for a presumed diagnosis of acute abdomen caused by a ruptured ovarian tumor with intra-abdominal bleeding. Intraoperative examination revealed normal adnexae bilaterally, but there was a cystic tumor in the pouch of Douglas that was strongly adherent to the surrounding intestines. This mass was connected to the posterior uterus by a stalk and appeared to be continuous with the uterine tissue. The postoperative pathological diagnosis was carcinosarcoma derived from subserous cystic adenomyosis. This is the first case report of carcinosarcoma developing from subserous cystic adenomyosis in the English literature as far as we know.

Abstract
Purpose Since 1986, the Japan Society of Obstetrics and Gynecology assisted reproductive technology (ART) registry system has collected data on national ART use and outcomes trends in Japan. Herein, we describe the characteristics and outcomes of ART cycles registered during 2020 and compare the results with those from 2019. Methods and Results In 2020, 621 ART facilities participated in the registration. The total number of registered cycles was 449 900, and there were 60 381 live births, which decreased from the previous year (1.79% and 0.36% decrease, respectively). The number of freeze-all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles increased in 2020, and the number of neonates born was 2282 for IVF-embryo transfer (ET) cycles and 2596 for ICSI cycles, which had decreased from the previous year. Frozen-thawed ET (FET) cycles had slightly increased from 2019 (0.04%). In 2020, 215 285 FET cycles were conducted, resulting in 76 196 pregnancies and 55 503 neonates. Single ET was performed in 81.6% of fresh transfers and 85.1% of frozen-thawed cycles, respectively, resulting in over 97% singleton pregnancies/livebirths rates. Conclusion Despite the COVID-19 pandemic during 2020, the overall number of ART cycles and neonates born demonstrated only a slight decrease in 2020 compared with 2019.

Abstract
Purpose Granulysin is a cytotoxic protein that simultaneously activates innate and cellular immunity. The authors aimed to evaluate whether granulysin is associated with the antiphospholipid antibody syndrome and whether heparin changes the granulysin levels. Methods A cohort study was performed with women with antiphospholipid antibody‐positive recurrent pregnancy loss (RPL). The authors examined granulysin levels under RPL and evaluated the changes in serum granulysin levels before and 1 week after the commencement of heparin treatment. Results Serum granulysin levels before heparin treatment were significantly higher in women who tested positive for one or more types of antiphospholipid antibodies (2.75 ± 1.03 vs. 2.44 ± 0.69, p = 0.0341 by Welch's t test), particularly anti‐phosphatidylethanolamine antibodies (IgG: 2.98 ± 1.09 vs. 2.51 ± 0.86, p = 0.0013; IgM: 2.85 ± 1.09 vs. 2.47 ± 0.77, p = 0.0024 by Welch's t test). After heparin treatment for 1 week, serum granulysin levels were significantly reduced (p = 0.0017 by the paired t test). The miscarriage rate was significantly higher in women whose serum granulysin levels were not reduced by heparin treatment (p = 0.0086 by Fisher's exact probability test). Conclusion The results suggest that heparin may reduce the incidence of miscarriage by suppressing serum granulysin levels. We examined granulysin levels under recurrent pregnancy loss and evaluated the changes in serum granulysin with heparin treatment. The miscarriage rate was significantly higher in women whose serum granulysin levels were not reduced by heparin treatment. The results suggest that heparin may reduce the incidence of miscarriage by suppressing serum granulysin levels.

Abstract
Purpose The Japan Society of Obstetrics and Gynecology records online annual cycle‐based information for assisted reproductive technology (ART). This report presents the characteristics and treatment outcomes of ART cycles registered during 2019. Methods The Japanese ART registry includes cycle‐specific information from 619 participating facilities, including treatment and pregnancy outcomes. Descriptive analyses were conducted for cycles registered during 2019. Results In 2019, 458 101 treatment cycles and 60 598 neonates were reported, both of which increased from 2018. The number of fresh cycles, including in vitro fertilization and intracytoplasmic sperm injection, decreased, while frozen‐thawed embryo transfer (ET) cycles increased. The mean maternal age was 37.9 years (standard deviation ± 4.7). Of 239 348 oocyte retrievals, 123 690 (51.7%) involved freeze‐all‐embryos cycles; fresh ET was performed in 41 831 cycles (a decreasing trend since 2015). In 2019, there were 211 597 frozen‐thawed ET cycles, resulting in 74 882 pregnancies and 54 168 neonates born. Single ET was performed in 82.6% of fresh transfers and 85.1% of frozen‐thawed cycles, with singleton live birth rates of 97.3% for both. Conclusions The number of fresh cycles decreased but frozen cycles increased in 2019. Single ET was performed in >80% of cases, and the proportion of babies born from frozen‐thawed ET increased.

Abstract
Abstract
Background
Patients with chronic thromboembolic pulmonary hypertension (CTEPH) represent right ventricular (RV) enlargement and hypertrophy, which consequently increase the RV myocardial perfusion. Although the main energy source of myocardium is fatty acid, it remains unknown whether myocardial fatty acid metabolism is altered in loaded RV. Herein, we report a novel approach to assess the RV perfusion and fatty acid metabolism, which is called SPECT-guided planar imaging.
Purpose
To evaluate if SPECT-guided myocardial perfusion and metabolic fatty acid planar imaging reflects the severity of the pulmonary hypertension in patients with chronic thromboembolic pulmonary hypertension.
Methods
The study groups included 30 patients with CTEPH and 20 healthy controls. In these patients with CTEPH, 15 patients underwent pulmonary thromboendarterectomy (PEA). Mean pulmonary artery pressure (mPAP) by right heart catheterization was obtained in all CTEPH patients. 201Thallium (201Tl) and iodine-123-beta-methyl iodophenyl pentadecanoic acid (123I-BMIPP) planar myocardial imaging was performed in all participants. For the patients undergoing PEA, repetitive SPECT-guided 201Tl and 123I-BMIPP planar imaging was performed one year after the procedure. To assess the RV overload, the planar images were performed in left anterior oblique position, optimized to separate the RV from the left ventricular (LV) using SPECT-guided transverse imaging. We measured the total counts of 201Tl and 123I-BMIPP in both the RV and LV. Moreover, we calculated their relative counts of the RV to LV (abbreviated as HR/HL (Tl) and HR/HL (BMIPP), respectively) to determine the indices of myocardial perfusion and fatty acid metabolism, respectively.
Results
Both HR/HL (Tl) and HR/HL (BMIPP) were elevated in the CTEPH patients compared with control (0.62±0.14 vs. 0.36±0.07, p<0.01 and 0.57±0.14 vs. 0.34±0.06, p<0.01, respectively). In the CTEPH patients, average mPAP was 44.0±9.52 mmHg, which was correlated with HR/HL (Tl) (r=0.675, p<0.001) and HR/HL (BMIPP) (r=0.685, p<0.01). Furthermore, the decrease of average mPAP 1 year after PEA was positively associated with the decrease of HR/HL (Tl) (r=0.646, p<0.01) and HR/HL (BMIPP) (r=0.504, p<0.05) 1 year after PEA.
Conclusions
In patients with CTEPH, RV myocardial perfusion and fatty acid metabolism was upregulated and moderately correlated with mPAP. SPECT-guided 201Tl and 123I-BMIPP planar imaging is a novel and noninvasive imaging modality to assess the severity of PH.

Abstract
At the 73rd Annual Congress of the Japan Society of Obstetrics and Gynecology, young doctors from Japan and South Korea made presentations on the present condition of risk-reducing surgery for hereditary breast and ovarian cancer (RRSO) in their respective country. RRSO was insured in Japan in April 2020, whereas in South Korea, it was insured 7 years earlier in 2013. In Japan, certification criteria have been set for facilities that perform RRSO, and the number of facilities is increasing, but regional disparities still exist in its distribution. The number of gBRCA1/2 testing facilities is larger, and the cost is more affordable in South Korea than in Japan. Additionally, South Korea provides genetic counseling to a wider range of relatives compared to Japan. In the future, as the indications for the gBRCA1/2 test have expanded as a companion diagnostic for the use of PARP inhibitors, it is expected that the number of candidates for the gBRCA1/2 mutation test and RRSO will increase in Japan. It is important to increase the number of BRCA tests while maintaining the quality of genetic counseling in order to provide adequate information on BRCA mutations and RRSO for patients to support their decision. For the development of hereditary breast and ovarian cancer (HBOC) medical care, it is necessary to publish a nationwide database in Japan and continue to analyze and discuss the data based on the results.

Abstract
BACKGROUND Miscarriage occurs in 10-15% of pregnancies and recurrent pregnancy loss (RPL) occurs in 1% of couples hoping for a child. Various risk factors, such as thrombophilia, uterine malformation, and embryonic chromosomal aberration cause RPL. We hypothesized that antithrombotic therapy for RPL patients with thrombophilia would reduce miscarriage due to thrombophilia, which would reduce the total miscarriages and result in a relative increase in miscarriage due to embryonic chromosomal aberrations. In this study, we investigated the incidence of chromosomal aberrations in products of conception in RPL patients with and without antithrombotic therapy. METHODS We performed a single-center, retrospective review of cases diagnosed as miscarriage with embryo chromosome analysis between July 1, 2000, and May 31, 2019. Rates of chromosomal aberration were compared between RPL patients with and without thrombophilia or antithrombotic therapy. RESULTS One hundred and-ninety RPL cases were analyzed. The average age was 37.4 ± 4.3 years, and the average number of previous pregnancy losses was 2.2 ± 1.1. The overall chromosomal aberration rate was 67.4% (128/190). There was no difference in the chromosomal aberration rate between the factors for RPL, with or without thrombophilia, and antithrombotic therapy. Only advancing maternal age had significant correlation to increased embryo chromosomal aberration rates. CONCLUSIONS With or without antithrombotic therapy, miscarriage was caused by embryonic chromosome abnormalities at a certain rate. Antithrombotic therapy in RPL patients with thrombophilia may reduce abortions due to thrombophilia, which may also normalize the rate of embryonic chromosome aberrations in the subsequent miscarriages.

Abstract
PURPOSE Since 2007, the Japan Society of Obstetrics and Gynecology (JSOG) has collected cycle-based data for assisted reproductive technology (ART) in an online registry. Here, we present the characteristics and treatment outcomes of ART cycles registered during 2018. METHODS The Japanese ART registry consists of cycle-specific information for all ART treatment cycles implemented at 621 participating facilities. We conducted descriptive analyses for such cycles registered for 2018. RESULTS In total, 454 893 treatment cycles and 56 979 neonates were reported in 2018: both increased from 2017. The mean maternal age was 38.0 years (standard deviation ± 4.7). Of 247 402 oocyte retrievals, 118 378 (47.8%) involved freeze-all-embryos cycles; fresh embryo transfer (ET) was performed in 50 463 cycles: a decreasing trend since 2015. A total of 199 914 frozen-thawed ET cycles were reported, resulting in 69 357 pregnancies and 49 360 neonates born. Single ET (SET) was performed in 82.2% of fresh transfers and 83.4% of frozen-thawed cycles, with singleton pregnancy/live birth rates of 97.2%/97.2% and 97.0%/97.2%, respectively. CONCLUSIONS Total ART cycles and subsequent live births increased in 2018. SET was performed in over 80% of cases, and the mode of ET has shifted continuously from using fresh embryos to frozen-thawed ones compared with previous years.

Abstract
Abstract
Background
In the development of heart failure, pathological intracellular signaling reactivates fetal cardiac genes, which leads to maladaptive remodeling and cardiac dysfunction. We previously reported that a transcriptional repressor, neuron restrictive silencer factor (NRSF) represses fetal cardiac genes and maintains normal cardiac function under normal conditions, while hypertrophic stimuli de-repress this NRSF mediated repression via activation of CaMKII. Molecular mechanisms by which NRSF maintains cardiac systolic function remains to be determined, however.
Purpose
To elucidate how NRSF maintains normal cardiac homeostasis and identify the novel therapeutic targets for heart failure.
Methods and results
We generated cardiac-specific NRSF knockout mice (NRSF cKO), and found that these NRSF cKO showed cardiac dysfunction and premature deaths accompanied with lethal arrhythmias, as was observed in our previously reported cardiac-specific dominant-negative mutant of NRSF transgenic mice (dnNRSF-Tg).
By cDNA microarray analysis of dnNRSF-Tg and NRSF-cKO, we identified that expression of Gnao1 gene encoding Gαo, a member of inhibitory G proteins, was commonly increased in ventricles of both types of mice.
ChIP-seq analysis, reporter assay and electrophoretic mobility shift assay identified that NRSF transcriptionally regulates Gnao1 gene expression.
Genetic Knockdown of Gαo in dnNRSF-Tg and NRSF-cKO by crossing these mice with Gnao1 knockout mice ameliorated the reduced systolic function, increased arrhythmogenicity and reduced survival rates.
Transgenic mice expressing a human GNAO1 in their hearts (GNAO1-Tg) showed progressive cardiac dysfunction with cardiac dilation. Ventricles obtained from GNAO1-Tg have increased phosphorylation level of CaMKII and increased expression level of endogenous mouse Gnao1 gene. These data suggest that increased cardiac expression of Gαo is sufficient to induce pathological Ca2+-dependent signaling and cardiac dysfunction, and that Gαo forms a positive regulatory circuit with CaMKII and NRSF.
Electrophysiological analysis in ventricular myocytes of dnNRSF-Tg revealed that impaired Ca2+ handling via alterations in localized L-type calcium channel (LTCC) activities; decreased T-tubular and increased surface sarcolemmal LTCC activities, underlies Gαo-mediated cardiac dysfunction.
Furthermore, we also identified increased expression of Gαo in ventricles of two different heart failure mice models, mice with transverse aortic constriction and mice carrying a mutant cardiac troponin T, and confirmed that genetic reduction of Gαo prevented the progression of cardiac dysfunction in both types of mice.
Conclusions
Increased expression of Gαo, induced by attenuation of NRSF-mediated repression forms a pathological circuit via activation of CaMKII. This circuit exacerbates cardiac remodeling and progresses heart failure by impairing Ca2+ homeostasis. Gαo is a potential therapeutic target for heart failure.

Abstract
PROBLEM Acute chorioamnionitis (aCAM) associated with microbial infection is a primary cause of preterm birth (PB). However, recent studies have demonstrated that innate immunity and sterile inflammation are causes of PB in the absence of aCAM. Therefore, we analyzed immune cells in the decidua of early to moderate PB without aCAM. METHOD OF STUDY Deciduas were obtained from patients with PB at a gestational age of 24+0 to 33+6 weeks without aCAM in pathological diagnosis. The patients were divided into two groups as follows: patients with labor and/or rupture of membrane (ROM) (no aCAM with labor and/or ROM: nCAM-w-LR), and patients without labor and/or ROM (no aCAM without labor and/or ROM: nCAM-w/o-LR). The immune cells and high mobility group box 1 (HMGB1) levels in the decidua were analyzed using flow cytometry. Co-culture of CD56+ cells with dendritic cells (DCs) and macrophages obtained from the decidua was also performed in the presence of HMGB1. RESULTS The nCAM-w-LR group demonstrated an accumulation of iNKT cells, and increased expression of HMGB1, TLR4, receptors for advanced glycation end products, and CD1d on DCs and macrophages. HMGB1 facilitated the proliferation of iNKT cells co-cultured with DCs and macrophages, which was found to be inhibited by heparin. CONCLUSIONS Inappropriate activation of innate immune cells and increased HMGB1 expression may represent parturition signs in human pregnancy. Therefore, control of these cells and HMGB1 antigenicity may be represent a potential therapeutic target for the prevention of PB.

Abstract
AIM Women undergoing infertility treatment often need to balance work and fertility treatment. Therefore, we evaluated the quality of life (QOL) and impact of infertility treatment on Japanese working women and their careers. METHODS We conducted an online questionnaire at 18 clinics in Japan. Responses were collected from 835 women, 713 of whom were working. The participants were divided into three groups based on treatment stage. Data were collected using the FertiQoL and an original questionnaire created by the authors. The Mann-Whitney U test and a multinomial logistic analysis were used. RESULTS Approximately 90% of the participants felt that treatment could hinder their work and 8% had quit their jobs. Low QOL was associated with sadness and despair due to infertility and mood disorders, disruptions to life and work, and the complicated medications and procedures involved in treatment. Social isolation and the effect of fertility treatment on daily life and work strongly hindered the careers of working women in the third stage of treatment (in vitro fertilization and intracytoplasmic sperm injection). Approximately 70% of the participants required support to subsidize treatment costs and sought shorter working hours and flextime systems. Only 55% informed their workplaces about the fertility treatment, but about 70% easily gained understanding by informing them. CONCLUSIONS For many working women, infertility treatment posed barriers to their careers, which could explain the low QOL. Urgent introduction of a support system is necessary in Japan, and understanding and social acceptance of infertility appears to be important.

Abstract
Anti-phosphatidylethanolamine antibody (aPE), an anti-phospholipid autoantibody (aPL), has been proposed as a factor in recurrent pregnancy loss (RPL). However, conflicting views exist on the pathogenicity of RPL, and aPE has not yet been included in the classification criteria for antiphospholipid syndrome (APS). Here, we aimed to determine the clinical importance of examining aPE. aPE (IgG, IgM) was measured in 1705 patients with a history of RPL and re-examined after a 12-week interval in patients who tested positive. Persistent positive patients were administered low-dose aspirin during the subsequent pregnancy and clinical outcomes depending on the presence, type, and persistence of aPE were evaluated. Among the patients positive for aPE IgG and aPE IgM in the first examination (n = 117; 6.87%, and n = 235; 13.6%, respectively), 31.5% and 37.6% were negative upon re-examination, respectively. Moreover, among the cases with known pregnancy outcome, the miscarriage rate in the cumulative positive aPE group was 32.6% (29/89), which did not differ significantly from that of the aPE negative group (27.7%; 80/209; P = 0.178). Alternatively, the miscarriage rate in the persistently positive group was 40.7% (22/54), which was significantly higher than that in the transient positive group, 20.0% (7/35) (P = 0.041). Particularly, this difference become more significant when focusing on aPE IgM, 46.9% (15/32) in the persistent, compared with 16.7% (4/24) in the transient positive group (P = 0.024). aPE IgM is suggested to serve as a pathogenic aPL together with anti-cardiolipin antibodies and lupus anticoagulants, particularly if these factors persist over an extended period of time.

Abstract
PURPOSE The Japan Society of Obstetrics and Gynecology (JSOG) has collected cycle-based assisted reproductive technology (ART) data in an online registry since 2007. Herein, we present the characteristics and treatment outcomes of ART cycles registered during 2017. METHODS We collected cycle-specific information for all ART cycles implemented at participating facilities and performed descriptive analysis. RESULTS In total, 448,210 treatment cycles and 56,617 neonates (1 in 16.7 neonates born in Japan) were reported in 2017, increased from 2016; the number of initiated fresh cycles decreased for the first time ever. The mean patient age was 38.0 years (standard deviation 4.6). A total 110,641 of 245,205 egg retrieval cycles (45.1%) were freeze-all cycles; fresh embryo transfer (ET) was performed in 55,720 cycles. A total 194,415 frozen-thawed ET cycles were reported, resulting in 66,881 pregnancies and 47,807 neonates born. Single ET (SET) was performed in 81.8% of fresh transfers and 83.4% of frozen cycles, with singleton pregnancy/live birth rates of 97.5%/97.3% and 96.7%/96.6%, respectively. CONCLUSIONS Total ART cycles and subsequent live births increased continuously in 2017, whereas the number of initiated fresh cycles decreased. SET was performed in over 80% of cases, and ET shifted from using fresh embryos to frozen ones.

Abstract
Detailed clinical and pathological features of placental mesenchymal dysplasia (PMD) complicated by preeclampsia (PE) are unknown. A 39-year-old nulliparous woman was referred at 19 weeks gestation. Ultrasound examination identified a fetus with severe growth restriction (-2.8 SD) and a markedly thickened placenta with many cystic structures suggestive of PMD. At 21 weeks, the patient developed severe hypertension (180/95 mm Hg) with marked proteinuria and an elevated serum soluble fms-like tyrosine-kinase-1 (sFlt-1) level (47,000 pg/L). The pregnancy was terminated to protect maternal health. Placental weight was 450 g and no histopathological findings of either proliferation or dysplasia were observed in the trophoblast. Villous chromosome examination revealed a 46XX karyotype, consistent with the diagnosis of PMD. In addition to the pathological findings of vascular endothelial dysfunction characteristic of the placenta in PE cases, enhanced expression of sFlt-1 in the syncytiotrophoblast of the enlarged villi was confirmed by immunohistochemistry as a novel finding in this condition. Monitoring of the serum sFlt-1 value is suggested to be a useful predictor of the pathological change associated with extremely early severe PE in PMD cases.

Abstract
Abstract
Background
We previously demonstrated that a transcriptional repressor, neuron restrictive silencer factor (NRSF), maintains normal cardiac function and electrical stability. Transgenic mice expressing a dominant-negative mutant of NRSF in their hearts (dnNRSF-Tg) exhibit systolic dysfunction with cardiac dilation and premature death due to lethal arrhythmias like human dilated cardiomyopathy (DCM). Underlining mechanisms remain to be elucidated, however.
Purpose
We studied underling mechanisms by which NRSF maintains normal cardiac function to identify novel therapeutic targets for heart failure.
Methods and results
We generated cardiac-specific NRSF knockout mice (NRSFcKO) and confirmed that cardiac phenotypes of NRSFcKO are similar to those of dnNRSF-Tg.
cDNA microarray analysis revealed that cardiac gene expression of GNAO1 that encodes Gαo, a member of inhibitory G protein Gαi family, is increased in both dnNRSF-Tg and NRSFcKO ventricles.
We confirmed that GNAO1 is a direct target of NRSF through ChIP-seq analysis, reporter assay and electrophoretic mobility shift assay.
In dnNRSF-Tg, pharmacological inhibition of Gαo with pertussis toxin improved systolic dysfunction and knockdown of Gαo by crossing with GNAO1 knockout mice improved not only systolic function but also frequency of ventricular arrhythmias and survival rates.
Electrophysiological and biochemical analysis in ventricular myocytes obtained from dnNRSF-Tg demonstrated that genetic reduction of Gαo ameliorated abnormalities in Ca2+ handling, which include increased current density in surface sarcolemmal L-type Ca2+ channel, reduced content of sarcoplasmic reticulum Ca2+ and lowered peak of Ca2+ transient. Furthermore, genetic reduction of Gαo attenuated increased phosphorylation levels of CAMKII in dnNRSF-Tg ventricles, which presumably underlies the improvement in Ca2+ handling. In addition, we identified increased Gαo expression in ventricles of heart failure model mice induced by transverse aortic constriction and cardiac troponin T mutant DCM model mice, in both of which, genetic reduction of Gαo ameliorated cardiac dysfunction.
Figure 1
Conclusions
We found that increased expression of Gαo, induced by attenuation of NRSF-mediated repression, plays a crucial role in the progression of cardiac dysfunction and lethal arrhythmias by evoking Ca2+ handling abnormality. These data demonstrate that Gαo is a potential therapeutic target for heart failure.

Abstract
Purpose A hysteroscopic metroplasty was performed for women with recurrent pregnancy loss owing to a uterine septum, following which some women became infertile. The aim of this study was to elucidate the risk factors of secondary infertility 1 year after hysteroscopic metroplasty for a uterine septum. Methods A retrospective, single-center, cohort study included women with a history of at least two miscarriages that had been attributed to a uterine septum who underwent a hysteroscopic metroplasty. The patients' background data were compared between the patients who conceived and those who remained infertile at 1 year postoperatively. The data were analyzed by using the Mann-Whitney U-test and multivariate analyses. Results The postoperative live birth rate was 83.9% (n = 26), with persistent infertility in five women at 1 year. When comparing the pregnancy group with the infertile group, the women in the postoperative infertility group were significantly older than those in the postoperative pregnancy group. The multivariate analysis showed that age was an independent risk factor for persistent infertility. Conclusion Age was identified as an independent risk factor for postoperative secondary infertility. Therefore, surgery as early as possible is recommended.

Abstract
AIM Acceleration-time/ejection-time ratio (At/Et ratio) of Doppler waveform is an established hemodynamic parameters that reflect proximal stenosis. Using this parameter, we evaluated whether perinatal low-dose acetylsalicylic acid (ASA) therapy could alter hemodynamics in the ductus arteriosus. METHODS Pulse Doppler measurements of the fetal ductus arteriosus were performed longitudinally from 20 to 37 gestational weeks in 106 healthy pregnant women (controls) and 65 pregnant women taking daily low-dose ASA (80 or 100 mg/day) because of a history of recurrent pregnancy loss. The At/Et ratio, pulsatility index (PI), and peak systolic velocity were evaluated and statistically analyzed. RESULTS The At/Et ratio significantly increased with gestational age in both the ASA group (r = 0.54) and the control group (r = 0.35), while the PI did not. Median peak systolic velocities also increased with gestational age in both the ASA group (r = 0.39) and the control group (r = 0.31). No significant differences in At/Et ratio, PI, or peak systolic velocity were observed between the ASA group and the control group. CONCLUSION Administration of low-dose ASA during pregnancy did not appear to alter hemodynamics in the fetal ductus arteriosus.

Abstract
PROBLEM The effectiveness of progesterone (P4) treatment for preventing preterm births is unclear. Its effects on the uterine cervix were tested using cultured human uterine cervical fibroblasts (UCFs). METHOD OF STUDY UCFs were incubated with lipopolysaccharide (LPS) in the presence or absence of P4 under various conditions. mRNA was subjected to PCR arrays and real-time RT-PCR to assess IL-6, IL-8, IL-1beta, PTGS2, MMP-1, and CXCL10 expression. RESULTS When exposed to a high-LPS concentration (2.0 μg/mL), expression of these genes was not suppressed by simultaneous P4 (1.0 μmol/L) treatment, but it was significantly inhibited when P4 was administered 1 hour prior to LPS, with the exception of the chemokines IL-8 and CXCL10. Expression of all genes was restricted by P4 under low-level LPS (0.2 μg/mL) stimulation, especially when administered prior to LPS treatment. CONCLUSION These data suggest that early or prophylactic P4 administration is an effective and important measure for reducing preterm birth risk.

Abstract
Osteopontin (OPN), a secreted glycoprotein, has multiple physiological functions. This study investigated the regulation and roles of OPN in the mouse ovary during the periovulatory stages. Immature female mice were treated with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) to simulate follicle maturation and ovulation. In situ hybridization and real-time RT-PCR were performed to assess expression of Opn in the periovulatory ovary. Granulosa cells (GCs) from PMSG-primed immature mice were cultured with or without hCG in the presence or absence of OPN, and effects on expression of Opn, progesterone synthesis, and vascular endothelial growth factor (VEGF) signaling were assessed by real-time RT-PCR, ELISA, and western blotting analysis. Opn transcripts were significantly upregulated 3 h after hCG treatment, followed by a peak at 16 h, and the transcripts localized to GCs. Incubation with hCG significantly increased quantities of Opn transcripts in GCs and OPN levels in the culture medium at 12 and 24 h. Furthermore, OPN treatment caused a significant increase in the levels of Star protein, P 450 cholesterol side-chain cleavage enzyme (p450scc), 3-beta-hydroxysteroid dehydrogenase (Hsd3b), and progesterone in the culture medium. OPN treatment promoted Vegf expression in GCs, which was significantly suppressed by a phosphoinositide 3-kinase (PI3K) inhibitor. In addition, OPN treatment stimulated phosphorylation of AKT, a downstream PI3K signaling molecule. In conclusion, expression of Opn was upregulated in mouse ovarian GCs in response to a gonadotropin surge through epidermal growth factor receptor signaling, which enhances progesterone synthesis and Vegf expression during the early-luteal phase.
