BACKGROUND: Cesarean section (C-section) rates are increasing globally, and repeated C-sections are associated with increased maternal morbidity. Trial of labor after C-section (TOLAC) is an approach to reduce the recurrence of C-sections. However, limited research exists on the impact of cesarean scars on labor duration in TOLAC, considering the termination of labor through C-section and selection bias. This study aimed to investigate the impact of cesarean scars on labor duration in TOLAC participants, accounting for potential confounding factors and biases. METHODS: This retrospective cohort study included 2,964 women who attempted vaginal birth at a single center in Japan from 2012 to 2021. The study categorized participants into TOLAC (n = 187) and non-TOLAC (n = 2,777) groups. Propensity scores were calculated based on 14 factors that could influence labor duration, and inverse probability of treatment weighting (IPTW) was applied. Cox proportional hazards regression analysis estimated hazard ratios (HRs) for labor duration, with and without IPTW adjustment. Sensitivity analyses used propensity score matching, bootstrapping, and interval censoring to address potential biases, including recall bias in the reported onset of labor. RESULTS: The unadjusted HR for labor duration in the TOLAC group compared to the non-TOLAC group was 0.83 (95% CI: 0.70-0.98, P = 0.027), indicating a longer labor duration in the TOLAC group. After adjusting for confounding factors using IPTW, the HR was 0.98 (95% CI: 0.74-1.30, P = 0.91), suggesting no significant difference in labor duration between the groups. Sensitivity analyses using propensity score matching, bootstrapping, and interval censoring yielded consistent results. These findings suggested that the apparent association between TOLAC and longer labor duration was because of confounding factors rather than TOLAC itself. CONCLUSIONS: After adjusting for confounding factors and addressing potential biases, cesarean scars had a limited impact on labor duration in TOLAC participants. Maternal and fetal characteristics may have a more substantial influence on labor duration.

INTRODUCTION: Chorioamnionitis (CAM) involves infection and inflammation of the chorion and amniotic membrane, but there are still no effective diagnostic biomarkers for CAM. METHODS: We investigated the correlation between RNA editing enzyme Adenosine deaminase family acting on RNA 1 (ADAR1) and CAM in chorion and amniotic membrane specimens derived from premature rupture of the membrane (PROM), CAM (pathologically diagnosed), and clinical CAM (clinically diagnosed) patients using reverse transcription polymerase chain reaction (RT-PCR). RESULTS: ADAR1 was upregulated in the chorion and amniotic membrane specimens of CAM and clinical CAM patients (p < 0.001 and p = 0.005). ADAR1 had a significantly higher area under the curve (AUC) (0.735 and 0.828) than markers of inflammation characteristics in diagnosing CAM and clinical CAM patients. ADAR1 also had significantly higher AUC (0.701 and 0.837) than clinical characteristics for CAM and clinical CAM patients. DISCUSSION: ADAR1 can be a useful diagnostic biomarker in CAM patients.

During the coronavirus pandemic, face-to-face simulation education became impossible. Therefore, we aimed to develop remote-access simulation education with a sense of realism through Information and Communication Technology (ICT) using a perinatal whole-body management and delivery simulator. In September 2021, we administered a multi-center simultaneous remote simulation based on our developed model. Ten universities in the Chugoku-Shikoku region were connected via a web-conferencing system to a live broadcast of a virtual vaginal birth in which a fictional hospitalized pregnant woman experienced accelerated labor and gave birth through vacuum delivery for fetal distress. A Video on Demand (VOD) was made beforehand using a new simulator that allowed for a visual understanding of the process of the inter-vaginal examination. We provided a participatory program that enhanced the sense of realism by combining VOD and real-time lectures on each scenario, with two-way communication between participants and trainee doctors using a chat function. Most participants answered "satisfied" or "very satisfied" with the content, level of difficulty, and level of understanding. From November 2021, we have used the videos of all processes in face-to-face classes. Our construction of a high-flexibility education system using remote simulation in the field of obstetrics and gynecology, especially in the vaginal delivery module, is unique, creative, and sustainable.

BACKGROUND: The role of barbed sutures in preventing myometrial defects and enhancing postpartum outcomes after cesarean section is uncertain. OBJECTIVE: This study compared clinical and ultrasonographic outcomes of uterine scar defects after C-section with barbed and conventional smooth thread sutures. STUDY DESIGN: This was a multicenter, parallel-group, randomized, controlled clinical trial. Four obstetrics and gynecology departments across three Japanese healthcare regions were included. The participants were women requiring their first cesarean delivery between May 2020 and March 2023. Of the 1211 participants enrolled, 298 underwent cesarean section and 253 were followed-up until July 2023. Participants with singleton pregnancies were randomly assigned (1:1 ratio) to receive either conventional or spiral thread sutures with a double-layer continuous suture. The study period comprised the time of consent to the 6- to 7-month examination. The primary endpoint was the rate of scar niches >2 mm evaluated using transvaginal ultrasonography at 6 to 7 months after surgery. Additional metrics included the total operative time, suture application time, operative blood loss, number of additional sutures required for hemostasis, maternal surgical complications, postoperative infections, surgeon's years of experience, and individual subscale scores. RESULTS: All data of the 220 participants (barbed suture group: 110; conventional suture group: 110) were available, thus enabling a full analysis set. A comparison of the barbed and conventional suture groups, respectively, revealed the following: niche length, 2.45±1.65 mm (range: 1.0-6.7) versus 3.79±1.84 mm (range: 1.0-11.0) (P<0.001); niche depth, 1.78±1.07 mm (range: 1.0-5.7) versus 2.70±1.34 mm (range: 1.0-7.3) (P<0.001); residual myometrial thickness, 8.46±1.74 mm (range: 4.8-13.0) versus 7.07±2.186 mm (range: 2.2-16.2) (P<0.001); and niche width, 1.58±2.73 mm (range: 0.0-14.0) versus 2.88±2.36 mm (range: 0.0-11.0) (P<0.001), respectively. The barbed suture group exhibited no defects and a residual myometrial thickness <3 mm. Furthermore, the barbed suture group had a lower rate of uterine niches (29.1%; n=32/110) than the conventional suture group (68.2%; n=75/110). Secondary outcomes showed no significant differences in operative times, maternal surgical complications, or postoperative complications. CONCLUSIONS: Double-layer barbed sutures during cesarean delivery may prevent cesarean section scar defects and postoperative complications.

Intramural pregnancy is a rare form of ectopic pregnancy, and the optimal treatment remains uncertain. We describe a 33-year-old woman (gravida 2, para 0) who visited our hospital with suspected ectopic pregnancy. The patient was asymptomatic and hemodynamically stable. Transvaginal ultrasonography revealed pregnancy at 6 weeks of gestation and a gestational sac and fetal heartbeat in the anterior muscular layer of the uterus, away from the endometrium. The fetal sac measured 26 mm. The serum human chorionic gonadotropin (hCG) level had increased to 27 655 mIU/mL. Accordingly, the patient was diagnosed with an intramural ectopic pregnancy and underwent total laparoscopic wedge resection using intraoperative ultrasonography. The postoperative course was uneventful, and she was discharged after 4 days. Her serum hCG level normalized at 26 days postoperatively. This case indicates that intraoperative laparoscopic ultrasonography seems viable for treating intramural pregnancies.

We investigated the effectiveness of simulation-based education in Focused Assessment with Sonography for Trauma (FAST) to increase the number of Emergency Medical Technicians (EMTs) capable of performing ultrasound examinations in vehicles under the guidance of a physician. Twenty-eight paramedics watched a 14-min video on the features of the ultrasound system, its use, and the scanning method for each part of the body. Each participant performed four FAST examinations using a portable ultrasound device, and the task performance was rated using the Task Specific Checklist (TSC) and Global Rating Scale (GRS). The time required for visualizing each examination site and each FAST was assessed. The mean time required for the first and fourth FAST was 144.6 ± 52.4 s and 90.5 ± 31.0 s, respectively. The time required for each test significantly decreased with repeated testing (p < 0.001). The time to complete FAST was significantly shortened for the pericardial cavity (33.4 ± 23.1/15.3 ± 10.6 s, p < 0.01), right thoracic cavity (25.2 ± 11.8/12.1 ± 8.3 s, p < 0.01), Morrison fossa (19.1 ± 10.8/10.8 ± 6.3 s, p < 0.05), and left thoracic cavity (19.0 ± 8.3/15.6 ± 8.3 s, p < 0.05). TSC and GRS scores were elevated, and all EMTs could obtain valid images. The combination of a brief video lecture and hands-on training significantly reduced the time required for FAST performance. Moreover, repeated practice enabled the EMTs to efficiently obtain accurate and clinically useful images.

PURPOSE: Among the Organisation for Economic Co-operation and Development countries, Japan has one of the lowest cervical cancer screening coverages. Cancer screening coverage has worsened due to the coronavirus disease of 2019 (COVID-19) pandemic. This study investigated the relationship between socioeconomic background, COVID-19 infection history and vaccine status, and regular cervical cancer screening (CCS) during the two years of the COVID-19 era in Japan. PATIENTS AND METHODS: We used data from the Japan COVID-19 and Society Internet Survey, a nationwide, Internet-based, self-report cohort observational study conducted in 2022. The outcome variable was identified by asking whether the participants had undergone CCS within the last two years. Cervical cytology was performed in Japan by brushing the external cervical os. This study used multivariate log-binomial regression models to evaluate inequalities during regular checkups for CCS. Adjusted prevalence ratios (APRs) with 95% confidence intervals (CIs) were estimated to incorporate the socioeconomic background variables. RESULTS: Of the 12,066 participants, 5597 (46.4%) had undergone regular CCS for over two years. The prevalence ratio (PR) of patients who underwent CCS was 0.70 for those in their 20s and 0.78 for those in their 60s, compared to those in their 40s. Socioeconomic inequities were found in the following groups: unemployed/student, unmarried, high school graduate or lower, and household income below 4 million Yen. Our final multivariate analysis revealed that participants who were in their 20s or 60s, had a household income below 4 million Yen, were unmarried, had no annual health check-ups, and were unvaccinated with COVID-19 were at a higher risk of not undergoing CCS. CONCLUSION: The relationship between socioeconomic inequality and CCS hesitancy is prevalent among younger participants. The CCS coverage in Japan during the COVID-19 pandemic year (2020-2022) was not low compared with the pre-pandemic era.

OBJECTIVE: To investigate the incidence and risk factors of small-for-gestational age (SGA) short stature at 2 and 3 years of age in SGA offspring born to women with hypertensive disorders of pregnancy (HDP). METHODS: We examined 226 women with HDP whose respective SGA offspring were delivered. RESULTS: Eighty offspring (41.2%) were diagnosed with SGA short stature. The prematurity before 32 weeks of gestation was the most significant factor for catch-up growth failure. CONCLUSION: In SGA offspring born to women with HDP, SGA short stature incidence was high, and the risk factor was prematurity before 32 weeks of gestation.

To date, there are no reports on the use of barbed sutures in myomectomy during pregnancy. Herein, successful laparotomic myomectomy at 15 weeks of gestation using barbed sutures is described. A 38-year-old pregnant woman with a large myoma (16 × 11 cm) underwent myomectomy at 15 weeks and 4 days of gestation because of strong pain at the myoma site, a high level of inflammatory markers with degeneration of uterine fibroids, and severe anemia caused by denaturation of myoma. The uterine wall was reconstructed using monofilament absorbable 0 barbed sutures. Unlike conventional sutures, barbed sutures do not retract, so an assistant does not need to hold onto it during reconstruction of the uterine wall, resulting in less pressure and damage to the gravid uterus while maintaining resistance and the ability to hold the tissue under tension. The pregnancy continued with no evidence of myometrial thinning or symptoms of preterm labor. The patient delivered a healthy baby via cesarean section due to partial placenta previa at 36 weeks. The case shows the satisfactory outcome of perinatal myomectomy using barbed sutures during pregnancy.

INTRODUCTION: Preeclampsia (PE) pathogenesis is explained by the two-stage disorder theory. However, mechanisms underlying hypertension and proteinuria in PE remain unclear. The role of (pro)renin receptor (PRR) in PE pathology has received special attention. We examined endothelin-1 (ET-1) production via placental PRR in a PE mouse model. METHODS: At 14.5 day-post-coitum (DPC), we performed a reduced uterine perfusion pressure (RUPP) operation, ligating the uterine arteriovenous vessels in female mice. We also infused these mice with a PRR inhibitor, decoy peptide in the handle region of prorenin (HRP) for mice (NH2-RIPLKKMPSV-COOH). At 18.5 DPC, blood, urine, and placenta were collected; fetus and placenta were weighed. We evaluated placental hypoxia using quantitative polymerase chain reaction (PCR), with hypoxia-inducible factor-1α (HIF-1α) as index. We also evaluated PRR, transforming growth factor-β1 (TGF-β1), and ET-1 expression in the placenta using quantitative PCR and western blotting. ET-1 concentration in blood plasma was assessed using enzyme-linked immunosorbent assay. RESULTS: Blood pressure and proteinuria significantly increased, and fetal and placental weights decreased in RUPP mice. HIF-1α, PRR, TGF-β1, and ET-1 expressions considerably increased in RUPP mice placentas. ET-1 concentration in RUPP mice blood plasma was markedly increased. PRR inhibitor suppressed these changes. DISCUSSION: In PE model mice that underwent RUPP treatment, placental hypoxia increased PRR and ET-1 expression suggesting a causative relationship between ET-1 and intracellular PRR signaling. RUPP treatment, when combined with HRP, reversed the effect of elevated ET-1 levels in the model. This study may help to elucidate the pathogenesis of PE considering PRR and ET-1.

BACKGROUND: Postpartum hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is more difficult to treat than HELLP syndrome during pregnancy. We describe a case of postpartum HELLP syndrome that responded to plasma exchange (PE) therapy. CASE PRESENTATION: A 30-year-old primipara woman was hospitalized for gestational hypertension at 33 weeks of gestation and underwent an emergent cesarean section at 36 weeks and 6 days of gestation due to rapidly progressing pulmonary edema. After delivery, liver dysfunction and a rapid decrease in platelet count were observed, and the patient was diagnosed with severe HELLP syndrome. She experienced multiple organ failure despite intensive care, and PE therapy was initiated. Her general condition dramatically stabilized within a few hours of PE therapy. CONCLUSION: It is controversial whether PE therapy should be used primarily in the management of HELLP syndrome, but early initiation of PE therapy could be effective for severe HELLP syndrome.

Abstract

Background

Knee osteoarthritis (KOA) is highly prevalent in older women, and previous studies suggest the involvement of hormonal factors play a role in the pathogenesis of osteoarthritis. KOA causes musculoskeletal impairment, resulting in decreased physical activity, muscle mass, and strength, which leads to sarcopenia and further increases the burden on healthcare systems. Oestrogen replacement therapy (ERT) improves joint pain and muscle performance in early menopausal women. Muscle resistance exercise (MRE) is a non-pharmacological method that preserves the physical functions of patients with KOA. However, data on short-term oestrogen administration combined with MRE in postmenopausal women, especially in those aged &gt; 65 years, are limited. Therefore, this study presents a protocol of a trial aimed to examine the synergistic effect of ERT and MRE on lower-limb physical performance in older women with KOA.

Methods

We will conduct a double-blinded, randomised placebo-controlled trial in 80 Japanese women aged &gt; 65 years living independently with knee pain. The participants will be randomly categorised into two groups: (1) 12-week MRE programme with transdermal oestrogen gel containing 0.54 mg oestradiol per push and (2) 12-week MRE programme with placebo gel. The primary outcome measured using the 30-s chair stand test, and secondary outcomes (body composition, lower-limb muscle strength, physical performance, self-reported measure of knee pain, and quality of life) will be measured at baseline, 3 months, and 12 months, and these outcomes will be analysed based on the intention-to-treat.

Discussion

The EPOK trial is the first study to focus on the efficacy of ERT on MRE among women aged &gt; 65 years with KOA. This trial will provide an effective MRE to prevent KOA-induced lower-limb muscle weakness, confirming the benefit of short-term oestrogen administration.

Pyomyoma is a rare condition that causes fever and abdominal pain associated with pregnancy, especially in the postpartum period. An appropriate diagnosis and early medical intervention are required to prevent serious complications. A 38-year-old primigravida with uterine fibroids had fever from the 11th day after cesarean section. The fever did not resolve despite repeated daily administration of broad-spectrum β-lactam antibiotics for 2 weeks. Although the physical examination did not show any lower abdominal pain, a pelvic magnetic resonance scan revealed degenerative fibroids, and myomectomy was performed. Yellow-greenish odorless pus inside the uterus was detected, and Mycoplasma hominis was detected in the pus culture. Mycoplasma species are resistant to broad-spectrum penicillin antibiotics and can cause pyomyoma. Pyomyomas may not cause uterine tenderness, and the causative organism may be difficult to identify; therefore, additional imaging studies should be considered.

BACKGROUND: Cases of uterine wall thinning and placental abnormalities complicated with systemic lupus erythematosus (SLE) during pregnancy have been reported in Asian countries for ten years. Long-term steroid use can cause muscle degeneration, but the mechanism of myometrium thinning was not known. Through the review of published articles, this report is the first review of cases to discuss the pathogenesis and clinical features of thinned myometrium and placenta accreta spectrum (PAS) in pregnant patients with SLE. CASE PRESENTATION: A twenty-nine-year-old primigravida with a history of lupus enteritis and paralytic ileus had a natural conception after less than two years of steroid treatment. An ultrasonographic study showed a thin uterine wall with a widespread thick placenta on the entire surface of the uterine cavity in the third trimester. At the 39th gestational week, she underwent a cesarean section due to the failure of the uterus to contract, even though the injection of oxytocin. There were several engorged vessels on the surface of the anterior uterine wall at the time of laparotomy. We decided to perform a hysterectomy because diffuse PAS replaced her uterus. CONCLUSION: A review of reported cases and our case shows an unusual complication of SLE that might be related to the particular condition of the estrogen-mediated immune system. Clinicians should always pay attention to the possibility of uterine wall thinning as uterine atony and the structural abnormality of the placenta for SLE patients with the unscarred uterus.

Polycystic ovary syndrome (PCOS) is a common endocrine metabolic disorder that is associated with high insulin resistance and obesity. However, ~70% of women with PCOS in Japan are non-obese. We retrospectively analyzed the cases of 163 Japanese women with PCOS who visited our Ob/Gyn department in 2006-2018 to determine which has a greater effect on insulin resistance: PCOS or obesity. We reviewed the women's medical records and calculated their insulin resistance and insulin secretion. The women's mean age and pre-pregnancy body mass index (BMI) were 30±5.8 years and 24.8±5.6 kg/m2, respectively; their mean ± SD fasting plasma glucose, 94.1±13.7 mg/dL; HOMA-IR, 2.1±2.0; QUICKI, 0.4±0.0; and HOMA-β, 108.9±88.0%. Sixtyeight women were pregnant, and 37% (n=25) were obese (BMI ≥ 25 kg/m2). Obesity had a greater effect on insulin resistance: fasting plasma glucose F(1, 53)=6.134, p<0.05; fasting insulin F(1, 53)=31.606, p<0.01; HOMA-IR F(1, 53)=31.670, p<0.01; QUICKI F(1, 53)=16.156, p<0.01. There was no significant difference in values other than QUICKI and testosterone between the women with and without PCOS. Obesity thus had a greater effect on increased insulin resistance in pregnant women with PCOS. Further studies of the insulin resistance of non-obese women with PCOS is needed, as non-obese women with PCOS are common in Asia.

Background: The incidence of severe uterine prolapse during childbirth is approximately 0.01%. Moreover, to the best of our knowledge, no reports detail the healing process of the cervix during uterine involution. This report describes successful vaginal delivery and the healing process of postpartum uterine prolapse and cervical tears in a patient with severe uterine prolapse. Case presentation: A patient in her 40s (gravida 3, para 1, abortus 1) with severe uterine prolapse successfully delivered a live female baby weighing 3190 g at 38 + 5 weeks of gestation by assisted vaginal delivery. Uterine prolapse had improved to approximately 2° by 2 months postoperatively. On postpartum day 4, during the healing process of cervical laceration, the thread loosened in a single layer of continuous sutures due to uterine involution, and poor wound healing was observed. The wound was subsequently re-sutured with a two-layer single ligation suture (Gambee suture + vertical mattress suture). However, on postpartum day 11, a large thread ball was hindering the healing of the muscle layer, which improved with re-suturing. Conclusion: Although vaginal delivery in a patient with severe uterine prolapse is possible in some cases, the cervix should be sutured, while considering cervical involution after delivery.

Extravillous trophoblast (EVT) invasion is important for embryo implantation, placental development, and successful remodeling of the uterine spiral artery. Endocrine gland derived-vascular endothelial growth factor (EG-VEGF) and matrix metalloproteinases (MMPs) are implicated in EVT invasion; however, the high con-centrations found in pregnancy pathologies have not been investigated in non-tumor trophoblasts. The roles of EG-VEGF, prokineticin receptors (PROKR1/2), MMP-2, and MMP-9 in EVT invasion during spiral artery remodeling were evaluated using human EVT from HTR-8/SVneo cell lines. The expression of MMP-2, MMP-9, and mitogen-activated protein kinase (MAPK), and Akt pathways in HTR-8/SVneo cells treated with recom-binant EG-VEGF alongside anti-PROKR1 and/or anti-PROKR2 antibodies was evaluated using quantitative reverse transcription-PCR and western blotting. Wound-healing and cell invasion assays were performed to assess the migration and invasion of these treated cells. Interestingly, 20 nM EG-VEGF activated ERK1/2 sig-naling and upregulated MMP-2 and MMP-9. This effect was suppressed by anti-PROKR2 antibody via ERK1/2 downregulation. Anti-PROKR2 antibody inhibited the migration and invasion of EG-VEGF-stimulated HTR-8/SVneo cells. Elevated concentrations of EG-VEGF enhance EVT invasion in a human trophoblast cell line by upregulating MMP-2 and MMP-9 via PROKR2. These new insights into the regulation of epithelial cell invasion may help in developing therapeutic interventions for placental-related diseases during pregnancy.

NIPT is non-definitive testing to estimate the possibility that fetuses have trisomy 21, trisomy 18, or trisomy 13. However, in NIPT-positive and indeterminate cases, rare chromosomal disease may become apparent, requiring advanced genetic considerations and counseling skills. We experienced two such cases, a trisomy 21 mosaicism case triggered by NIPT-positive status and 18q deletion syndrome triggered by NIPT-indeterminate status. These cases have two clinical implications for NIPT. First, it was revealed that trisomy mosaicism might be found in NIPT-positive cases that have lower Z-Scores than those inferred from the fraction of fetal cfDNA in the case of standard trisomy. Second, it is possible that microdeletion syndrome could be the reason for an indeterminate NIPT result. Today's genetic counseling requires more expertise in ethics and communication as well as genetic science because NIPT can lead to totally unexpected results.

Pregnancy was reported to be a risk factor for coronavirus disease 2019 (COVID-19), with an increased risk for premature birth. Corticosteroids and remdesivir are used for patients with COVID-19; however, there is no established treatment for these patients. In particular, the effective management of pregnant, critically ill patients with COVID-19 remains unknown. We describe a 34-year-old, critically ill woman at 30 weeks of gestation with COVID-19, who was successfully treated with remdesivir and combined high-dose betamethasone (12 mg/day for two days) and methylprednisolone (125 mg/day for three days) followed by steroid tapering. During treatment, fetal biophysical profile scores on obstetric ultrasound were normal; her pregnancy course progressed well. Since high-dose corticosteroids improve fetal lung maturation and as well as cytokine storm due to COVID-19, this case provides an insight into the management of pregnant COVID-19 patients.

BACKGROUND: The aim of this randomized controlled trial (RCT) is to investigate whether Spiral-thread sutures are superior to conventional sutures (0-Vicryl) for preventing uterine scar thinning following elective cesarean section. METHODS: This multicenter, parallel-group RCT will be conducted in four hospitals across three medical regions in Japan to assess 200 women (≥20 years old) with singleton pregnancies who are scheduled to undergo cesarean sections. Eligible women will be randomly assigned (1:1 ratio) to receive either the conventional uterine suture continuous absorption thread, which is most commonly used in Japan, or the Spiral thread. The primary endpoint is the degree of scar thinning, measured by transvaginal ultrasonography 6-7 months postoperatively, to evaluate the position of the uterus (anterior or posterior tilt) and myometrial wound thickness. The degree of thinning will be compared between the groups, and four measurements (mm) of the thinning area, including caudal distance, depth of the depression, remaining thickness of the myometrium on the serous side of the most depressed area, and width of the depression, will be recorded in the sagittal view on transvaginal ultrasound. Secondary endpoints will include total operative time, suture application time (from birth to the end of uterine suturing), operative blood loss, number of additional Z-sutures or continuous sutures required to stop bleeding, maternal abnormality frequency (surgical complications and postoperative infections), surgeon's years of experience, and clinical interpretation of individual subscale scores. DISCUSSION: This study shall provide important evidence on the optimal suture for preventing hysterotomy wound thinning after the first cesarean section. TRIAL REGISTRATION: National Institute of Public Health, Japan: jRCT1062200001 (May 7, 2020; https://rctportal.niph.go.jp/en/detail?trial_id=jRCT1062200001) and Okayama University Certified Review Board: CRB6180001 (April 9, 2020, version 3.0).

Early diagnosis and therapy are important in a cesarean scar pregnancy (CSP), which can cause uterine rupture with resultant massive bleeding. However, there are some reports of CSPs continued to term. The optimal management of CSPs remains unclear; therefore, we investigated the clinical courses of CSPs diagnosed and treated at perinatal institutions in the Chugoku and Shikoku regions of Japan. We enrolled 60 women diag-nosed with CSP at 21 institutions from January 2006 to December 2015. Of the 60 women diagnosed with CSP, 57 were treated. Pregnancy was terminated in 48 women and continued in 9. Thirteen women underwent transabdominal hysterectomy; they experienced no postoperative complications or allogeneic blood transfu-sion. Nine women received therapies such as dilation and curettage, and 26 received non-surgical therapies such as methotrexate and topical administration of potassium chloride. Among 9 women who chose to con-tinue with their CSP, 7 successfully delivered newborns, 2 had uterine ruptures in the second trimester, and all women required transabdominal hysterectomy. Diagnosis and therapy in the first trimester of pregnancy are important in the management strategy of a CSP. When continuing a CSP, the risk of uterine rupture and trans-abdominal hysterectomy must be considered.

OBJECTIVE: To retrospectively investigate cesarean scar pregnancy (CSP) patients who received systemic methotrexate (MTX) and to clarify the criteria for administering systemic MTX to CSP patients. MATERIALS AND METHODS: Fifteen CSP patients who were initially treated with systemic MTX (50 mg/m2/week) were included. Nine patients, who needed a uterine artery embolization (UAE) or a laparotomy, including a transabdominal hysterectomy (TAH), were defined as the unsuccessful MTX group. Six patients who did not require UAE or a laparotomy were defined as the successful MTX group. Furthermore, the hCG cut-off value and the GS cut-off size at the time of CSP diagnosis, which differentiated successful and unsuccessful patients, were defined. MTX success rates were investigated by combining the hCG and gestational sac (GS) size cut-off values. RESULTS: The hCG cut-off value was 17757.0 mIU/mL, and the GS cut-off size was 10.4 mm. In patients with hCG values less than 17757.0 mIU/mL, the MTX success rate was 75.0%. Fewer patients needed UAE or a laparotomy compared to patients with hCG values higher than 17757.0 mIU/mL (P = 0.007). In patients with a GS size less than 10.4 mm, the MTX success rate was 80.0%. Fewer patients among them needed UAE or a laparotomy compared to those among patients with a GS size greater than 10.4 mm (P = 0.089). In patients with hCG values and GS sizes lower than the cut-off values, the MTX success rate was 80.0%. Fewer patients among them needed UAE or a laparotomy compared to those among patients with hCG values and/or GS sizes higher than the cut-off values, respectively (P = 0.010). CONCLUSION: Patients with hCG values less than 17757.0 mIU/mL and GS sizes less than 10.4 mm may have a greater chance of successful systemic MTX treatment when it is used as the first line of treatment for CSP.

A 30-year-old pregnant woman developed postpartum HELLP syndrome. Abdominal computed tomography revealed a high-density vessel structure in contact with the right kidney and connected to the right ovarian vein, suggesting thrombosis in the right inferior renal capsular vein (RCV). RCV thrombosis is a rare thrombotic disorder in postpartum women, and hypercoagulability related to the pregnancy complications may be the predisposing factor. The potential risk for pulmonary embolism in the rare pregnancy-related thrombosis should be recognized.

BACKGROUND: Two-dimensional (2D) speckle tracking echography (STE) is a new diagnostic modality that allows for the assessment of myocardial deformation. The present study assessed the feasibility of fetal 2D-STE at a high frame rate and determined the reference values for left ventricular (LV)- and right ventricular (RV)- global longitudinal strain (GLS). METHODS: In this prospective study, 109 fetuses with gestational ages ranging from 18 to 38 weeks underwent 2D echocardiography between August 2018 and December 2019. All recordings were performed using the Aplio i800 (CANON Medical Systems Corporation, Tochigi, Japan) and a convex probe (4 MHz) for fetuses. RESULTS: Longitudinal peak systolic strain measurements were obtained in 98 of 109 healthy fetuses (90%). All ultrasound videos were recorded with a median frame rate of 172 (range, 100-274) frames/s. The LV-GLS was almost constant, regardless of the number of weeks since the second trimester (r = -0.0087, p = ns). The RV-GLS decreased significantly with gestational age (r = 0.39, p < 0.01). CONCLUSIONS: STE may be useful for quantifying the systolic myocardial function in a fetus.

Owing to new surgical procedures and medications, more women who have undergone the Fontan procedure reach childbearing ages. We report five cases of pregnancy with Fontan circulation. Case 1 had subchorionic hematoma (SCH), fetal growth restriction (FGR), and preterm labor (PTL). She delivered a 1073 g infant via cesarean section at gestation week 28 because of hemorrhagic shock. Case 2 delivered 2142 g and 2232 g infants at gestation weeks 37 and 36, respectively. She had FGR, PTL, and postpartum hemorrhage (PPH). Case 3 had SCH, PTL, and heart failure. At 36 weeks, labor was induced and she delivered a 2546 g infant by vacuum extraction with epidural analgesia. Cases 4 and 5 resulted in miscarriage. All subjects experienced obstetrical complications. This report discusses pregnant women with Fontan circulation by focusing on affected Japanese women. <Learning objective: More women who have undergone the Fontan procedure reach childbearing ages due to the new surgical procedures and medications. We report five cases and all of them experienced obstetrical complications. Anticoagulation might be one of the causes of postpartum hemorrhage. Labor epidural analgesia could contribute to minimized dynamic circulatory changes during labor. This report can be the literature regarding pregnant women with Fontan circulation in Japan.>.

An association between preeclampsia and (pro)renin was recently reported. Intracellular signaling of the (pro) renin receptor [(P)RR] increases the expressions of TGF-β and PAI-1. In this study we sought to clarify the involvement of (pro)renin in the pathogenesis of preeclampsia via the intracellular signaling of (P)RR on preeclampsia placentas. Activated (pro)renin plasma concentrations were compared between pregnant women with (n=15) and without (n=28) preeclampsia. The placentas were immunohistochemically evaluated with anti-HIF-1α and anti-(P)RR antibodies. HTR-8/SVneo cells were cultured under hypoxic conditions and treated with human recombinant (pro)renin. The mRNA expressions of HIF-1α, (P)RR, PAI-1, TGF-β, and ET-1 were also examined by real-time RCR. The activated (pro)renin plasma concentration was significantly higher in the third vs. the second trimester in the preeclampsia patients. HIF-1α and (P)RR expressions were significantly increased in the preeclampsia placentas. The mRNA expressions of PAI-1, TGF-β, and ET-1 were significantly increased in the experiments using recombinant (pro)renin vs. hypoxic conditions. (P)RR expression in preeclampsia placentas is increased by persistent hypoxia through the second and third trimesters, and PAI-1, TGF-β, and ET-1 production is increased via (P)RR. Our results suggest that ET-1 production via the intracellular signaling of (P)RR is important in the pathogenesis of preeclampsia.

AIM: Changes in glucose levels during labor have not been sufficiently investigated in pregnant women. Using real-time continuous glucose monitoring, we aimed to assess glucose kinetics during labor among pregnant women with gestational diabetes mellitus (PwGDM), and those with normal glucose tolerance (PwNGT). METHODS: Japanese PwGDM and PwNGT who had planned a transvaginal delivery at Okayama University Hospital were enrolled. The correlation between changes in glucose levels during labor among the PwGDM and PwNGT groups at four time periods was assessed: (i) active phase of 1st stage of labor; (ii) 2nd stage of labor; (iii) postpartum 0-12 h; and (iv) postpartum 12-48 h. RESULTS: In total, 18 and 22 PwGDM and PwNGT, respectively, were enrolled. During labor, both groups had similar changes in glucose levels over time, which peaked during period 3. The main effect of glucose level changes was the labor period (P < 0.001), not the presence of gestational diabetes mellitus. Furthermore, differences in glucose levels in the PwGDM group were observed between periods 1 and 2 (P = 0.037), 1 and 3 (P = 0.024), 3 and 4 (P = 0.005); differences in glucose levels in the PwNGT group were observed between periods 3 and 4 (P = 0.024). CONCLUSION: During labor, both PwGDM and PwNGT groups showed similar changes in glucose levels over time. During delivery, the PwGDM who regularly measured their own glucose levels could be managed using the same nutritional management methods as those for PwNGT.

Nager syndrome is a rare disease involving severe micrognathia and upper limb shortening. In this report, we describe a case in which micrognathia of the fetus was suspected based on the observation of upper limb shortening during detailed B mode and 3D/4D ultrasonographic observation, and combined fetal MRI and 3D-CT led to a prenatal diagnosis of Nager syndrome. Upon birth, because severe micrognathia caused airway obstruction and made it difficult to spread the larynx for intubation, effective ventilation could not be carried out and a tracheostomy was necessary. Since a differential diagnosis of Nager syndrome can be made based on the fact that micrognathia typically co-occurs with upper limb shortening, it is possible to diagnose the disease before birth and prepare for life-saving measures accordingly.

Radical trachelectomy (RT) is a fertility-sparing surgery for cervical cancer. Postoperative pregnancies have a high risk of abortion and prematurity. To prevent this, a procedure involving transabdominal cerclage (TAC) was devised for shortened cervical canals post-RT. Here we describe the successful management of a pregnancy after abdominal RT (ART). The 34-year-old patient was gravida 1, para 0. When she was 27, she underwent ART for stage Ib1 cervical cancer, and she became pregnant 7 years later. Because her cervical canal was 16.7 mm during early pregnancy, we performed TAC at 12 weeks of pregnancy. Post-surgery, we administered an infusion of ritodrine hydrochloride for tocolysis. A selective caesarean section was performed at 36 weeks, with the delivery of a healthy infant.

Abnormal glucose metabolism during pregnancy is an established risk factor for preeclampsia (PE). Disruption of the balance between placental angiogenic factors is linked to PE pathophysiology. We examined whether hypoxia-induced factor-1α (HIF-1α) and protein kinase Cβ (PKCβ) are involved in the regulation of placental angiogenic factors under high-glucose conditions in vitro. The human choriocarcinoma cell lines BeWo and JEG-3, and the human trophoblast cell line HTR-8/SVneo were cultured with 10 and 25 mmol/L glucose [control glucose group (CG) and high-glucose group (HG), respectively]. We examined the changes in HIF-1α, soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), and vascular endothelial growth factor (VEGF) expression in the CG and HG by real-time PCR and ELISA. PKC activation was also measured by ELISA. The expressions of HIF-1α, sFlt-1, PlGF, and VEGF were significantly higher in the HG than in the CG. PKC activity was significantly increased in the HG. High glucose affected the expression of angiogenic factors in choriocarcinoma cells via the PKCβ and HIF-1α pathways, suggesting their involvement in PE pathogenesis.

AIMS/INTRODUCTION: To measure longitudinal changes in resting energy expenditure and body composition of Japanese pregnant women with or without diabetes. MATERIALS AND METHODS: The study population consisted of women who had delivered a live singleton neonate after 22 weeks' gestation at Okayama University Hospital from July 2013 to June 2017. Resting energy expenditure and body composition were measured in the first trimester, second trimester, third trimester and postpartum. RESULTS: A total of 144 women participated in this study: 103 with normal glucose tolerance and 41 with diabetes. The resting energy expenditure (kcal/day) of pregnant women with normal glucose tolerance was significantly higher in the third trimester (1,644 ± 234) than in the first (1,461 ± 215) and second trimesters (1,491 ± 219), and postpartum (1,419 ± 254), whereas that of pregnant women with diabetes did not significantly change during all periods (1,568 ± 404, 1,710 ± 332, 1,716 ± 251, 1,567 ± 249). The resting energy expenditure of women with good glycemic control was lower than that of women with poor control. Fat-free mass was closely correlated with resting energy expenditure. CONCLUSIONS: The resting energy expenditure of Japanese pregnant women with normal glucose tolerance was significantly increased in the third trimester. The resting energy expenditure of women with good glycemic control was lower than that of women with poor control. Resting energy expenditure and fat-free mass are potential indexes for medical nutrition therapy in pregnant women with diabetes.

AIMS: There is no previous study comparing the predictive ability of maternal pre-pregnancy body mass index (BMI) versus a 75-g oral glucose tolerance test (OGTT) in early pregnancy for large-for-gestational-age (LGA) infants. METHODS: This multi-institutional prospective cohort study included 966 pregnant Japanese women. A multiple logistic regression model was applied to compare the effect size of pre-pregnancy BMI, fasting plasma glucose (PG), and 1- and 2-h PG levels after a 75-g OGTT performed before 22weeks gestation for LGA. After these variables were included separately into the model as per continuous variables 1 standard deviation (SD) increase, they were included simultaneously. RESULTS: When pre-pregnancy BMI, fasting PG, and 1- and 2-h PG after a 75-g OGTT were separately included in the model, the adjusted odds ratios (ORs) for LGA per 1 SD increase in pre-pregnancy BMI, fasting, and 1- and 2-h PG were 1.55 (95% confidence interval [CI]: 1.26-1.91), 1.26 (95% CI: 1.03-1.54), 0.99 (95% CI: 0.78-1.25), and 1.17 (95% CI: 0.93-1.49), respectively. When these variables were included simultaneously, the adjusted ORs per 1 SD increase in pre-pregnancy BMI, fasting, and 1- and 2-h PG were 1.52 (95% CI: 1.23-1.88), 1.19 (95% CI: 0.96-1.46), 0.77 (95% CI: 0.57-1.03), and 1.30 (95% CI: 0.96-1.76), respectively. CONCLUSIONS: Maternal pre-pregnancy BMI was more strongly associated with LGA compared with a 75-g OGTT in early pregnancy. Health-care providers should recognize that women with a higher pre-pregnancy BMI carry a higher risk for having LGA infants regardless of the results of a 75-g OGTT.

Cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy. Because CSP carries a high risk of uterine rupture and life-threatening bleeding, the pregnancy should be terminated upon confirmation of diagnosis. There have been few reports of CSP with successful delivery. We present a case of CSP under expectant management, with delivery via planned cesarean section at 35 weeks of gestation. This report suggests that successful pregnancy outcome can be achieved in some women with uterine cesarean scar, but further analysis and additional studies are required in order to describe the optimal protocol of expectant management in CSP.

Although gestational hypertension (GH) is thought to be different from preeclampsia (PE), in Japan GH and PE are usually treated as the same disease (i.e., pregnancy-induced hypertension). Here we sought to determine whether there are any differences in fetal growth and maternal kidney function between pregnancies with PE and those with GH. We retrospectively analyzed 61 GH patients and 60 PE patients with singleton pregnancies who delivered at Okayama University Hospital (2008-2015). We compared maternal and perinatal outcomes and maternal kidney function parameters between the GH and PE pregnancies. The mean values of maternal age (p=0.01), gestational age at delivery (p<0.0001), placental weight (p=0.002), birth weight and height (p<0.0001, p=0.0001), and head circumference standard deviation score (p=0.007) of newborns of the GH group were significantly higher than those of the PE group. The duration until termination of PE or GH was not significantly correlated with kidney function. The birth weight percentile was significantly correlated with kidney function in PE but not GH. However, GH patients with poor kidney function and small-for-gestational age infants showed perinatal outcomes similar to those of the PE group. Monitoring kidney function is thus important for determining the severity of PE and GH.

PURPOSE: We continuously measured bilateral uterine artery (UA) blood flow and compared differences in UA blood flow to investigate the differences in pathophysiology between early- and late-onset pregnancy-induced hypertension (PIH) and the usefulness of continuous monitoring of UA blood flow for the prediction of early-onset PIH. METHODS: The subjects were 76 PIH patients. The mean pulsatility index of bilateral UA (UAPI), an early diastolic notch in the velocity waveform, and regression curves were retrospectively examined and compared between early- and late-onset groups and the groups with and without fetal growth restriction (FGR). RESULTS: Regression curves of the UAPI in the early-onset group persisted at +2.0 standard deviations or more from the second to third trimester, while the UAPI in the late-onset group stayed within the normal range. A significantly higher mean UAPI with a high frequency of an early diastolic notch was observed in the early-onset group compared with the late-onset group in all pregnancy trimesters. There was a significant difference in UA resistance between the mild and severe groups and between the FGR and non-FGR groups, but to a small extent compared with the onset period. CONCLUSION: There was a difference in pathophysiology between early- and late-onset PIH. Continuous monitoring of UA blood flow might be useful for the prediction of early-onset PIH if high UA resistance has been observed.

The constitutive androstane receptor (CAR) has been reported to decrease insulin resistance along with obesity. 6,7-dimethylesculetin (DE) is an active component of Yin Zhi Huang which is a traditional Asian medicine used to treat neonatal jaundice via CAR. In this study, we examined whether DE could affect the expression of gluconeogenic and lipogenic genes via human CAR pathway using human HepG2 cells in vitro. We also studied whether DE treatment during pregnancy could prevent maternal hypertension, glucose intolerance and hyperlipidemia, and fetal overgrowth in high-fat diet (HFD)-induced obese pregnant mice. Dimethylesculetin suppressed the mRNA expression of gluconeogenic genes, phosphoenolpyruvate carboxykinase and glucose-6-phosphatase, and lipogenic genes, sterol regulatory element-binding protein 1 and stearoyl-CoA desaturase 1, and enhanced CAR-mediated transcription. Blocking the CAR-mediated pathway abolished the effect of DE in vitro. DE treatment during pregnancy could prevent maternal hypertension, glucose intolerance and hyperlipidemia, and fetal overgrowth in HFD-induced obese pregnant mice in vivo. Our data indicate that DE might be a potential therapeutic agent for obese pregnant patients with insulin resistance through CAR to prevent the perinatal outcomes such as preeclampsia, gestational diabetes, and macrosomia. Further analysis of possible complications and side effects using animal models is required.

【目的】当院では2004年より硬膜外無痛分娩を施行している。当院では本人希望,母体適応の患者は24時間体制で麻酔科医による硬膜外無痛麻酔を行っている。また,分娩時にも可能な限り麻酔科医が立ち会い急変に対応する。当院における3年間の硬膜外無痛分娩症例における周産期転帰について検討した。【方法】正期産で分娩となった妊婦を対象とし,無痛あり経腟分娩を無痛分娩群,無痛なし経腟分娩を非無痛分娩群として診療録を後方視的に検討した。選択的帝王切開,多胎妊娠,子宮内胎児死亡の症例は除外した。【結果】2018年1月から2020年12月までの総分娩数は1269例であった。除外例を除き無痛分娩群は142例,非無痛分娩群は643例であった。無痛分娩群では器械分娩19.7%(28/142例),陣痛促進剤78%(111/142例),分娩時出血量300ml(50-1800),緊急帝王切開率5.3%(8/150例)であったのに対し,非無痛分娩群ではそれぞれ8.1%(52/643例),51%(331/643例),240ml(20-3130),8.7%(62/710例)と無痛分娩群で有意に器械分娩率,陣痛促進剤使用率が高く,分娩時出血量が多かった。無痛分娩群の初産婦,経産婦の分娩第2期遷延率はそれぞれ26%(25/98例),18%(8/45例)であり,非無痛分娩群ではそれぞれ17%(62/367例),10%(29/281例)と両群で有意差は認めなかった。新生児のApgar score,臍帯動脈血pHには有意差を認めなかった。【結論】既存の報告では硬膜外無痛分娩により帝王切開率は増加しないが,器械分娩率・陣痛促進率は増加するとされている。本検討でも同様の結果となり,非無痛分娩群と比較して母児の予後や帝王切開率は大きく変わらなかった。麻酔科の協力を得て計画分娩にすることなく適切な介入を行うことで帝王切開率を上昇させず,安全な無痛分娩を提供できていると考えられる。(著者抄録)

胎児先天性心疾患の妊婦への多職種による介入と、倫理的配慮を2例(26歳初産婦、35歳3回経産婦)報告した。26歳の妊婦は長期の不妊治療を経ての妊娠であり、夫婦双方の両親が健在であった。35歳の妊婦は夫婦の希望で4人目を自然妊娠し、上の子どもは入学を控え、夫婦の両親は遠方在住で持病があった。26歳の妊婦は心疾患への積極的治療を選択し、地域保健師、医療ソーシャルワーカーとも連携しながら分娩の日を迎え、父親の愛着形成、両親の受け入れも良好であった。35歳の妊婦は「家族のサポートはなく、この子にかかりきりになれない。経済的不安もあり手術は望まない」と心疾患への治療を拒否していた。多職種からの情報提供を繰り返し行ったが、治療拒否の意思は変わらなかった。妊娠37週に分娩となり、生後2日間、児が永眠するまで母児同室を行い、家族で看取った。方針を一律に定めることは難しく、議論を重ねていくことが重要と考えられた。

蘇生的大動脈内バルーン遮断(以下REBOA)は外傷性ショックに対する出血の制御手段である。今回、我々は救急外来で産科危機的出血搬送2症例に対しREBOAを使用したので報告する。【症例1】43歳 2妊1産。妊娠41週1日に予定日超過で陣痛誘発を開始。胎児心音低下後、徐脈が継続し吸引分娩にて児は娩出。娩出直前より母体の酸素化不良、血圧低下、出血量2070mlと羊水塞栓症が疑われたため事前に情報共有しつつ、前医から救急搬送。初療時血圧46/36mmHg、E4V4M6、子宮は弛緩状態で大量出血が持続していた。輸血製剤や子宮用手圧迫にて対応しつつ、病着から29分でREBOAを挿入した。緊急開腹下で単純子宮全摘+両側卵管切除術施行。総出血量9000ml。【症例2】37歳 7妊5産。妊娠37週3日に前期破水を理由に陣痛誘発を開始。2時間で児は娩出。分娩直後より血圧低下、不穏状態と出血量2500mlを認め、事前に情報共有しつつ、前医から救急搬送。橈骨動脈触知不可、E3V3M5、大量輸血開始後より急速に増大する腹部緊満化を認め、病着から32分でREBOAを挿入。分娩経過と身体所見から子宮破裂による腹腔内出血と推定。止血目的に緊急開腹下単純子宮全摘+両側卵管切除術施行。総出血量1000ml。【結語】2症例とも県内で配備される緊急搬送補助システムを利用し、妊産婦情報を他科と到着前に共有し事前準備を行い、迅速なREBOAや大量輸血の応急処置が可能であった。様々な原因から発症する産科危機的出血は外傷性ショックに類似した対応が求められるが、REBOAの使用に関しては産科危機的出血への今後の報告が待たれ、検討していく必要がある。(著者抄録)

目的:産後の過多出血に対する客観的評価として、ダイナミック造影CT検査の有用性が報告されている。ダイナミック造影CT検査を施行することは、視診や超音波検査のような主観的評価よりも優れた検査特性を示すか否かを検討した。方法:産後の過多出血の診断でダイナミック造影CT検査を施行した37例を対象とし、早期相で子宮腔内に血管外漏出を認めた群と、後期相のみで子宮腔内に血管外漏出を認めた群、早期相、後期相ともに子宮腔内に血管外漏出を認めなかった群に分けて後方視的研究を行った。結果:早期相で子宮腔内への血管外漏出を認めた群は14例あり、うち12例が経カテーテル的動脈塞栓術を施行、2例が峡部裂傷部位を内側から圧迫する子宮内バルーンタンポナーデにより加療した。後期相で初めて子宮腔内への血管外漏出を認めた3例は全て保存的療法が奏功し、早期相、後期相とも子宮腔内への血管外漏出を認めない10例もすべて保存的療法が奏功した。早期相で子宮腔内への血管外漏出を認めた場合は、その時点での目に見える出血量が少なくとも、基本的に経カテーテル的動脈塞栓術を行わないと止血されないことが示唆された。また、ダイナミック造影CT検査は産後の過多出血に対して診断の遅れや病変の見逃しがなく、正確な診断と瞬時の治療方針決定に有用であることが示された。結論:産後の過多出血は出血の程度や超音波検査のみで治療方針を選択するのではなく、ダイナミック造影CT検査を行い動脈性の活動性出血の有無で選択することの有用性が示された。(著者抄録)

先天性横隔膜ヘルニア(Congenital Diaphragmatic hernia:CDH)に合併した胸部異所性腎は非常に稀な疾患である。今回、我々は出生前診断に至った症例を経験したため報告する。症例は30歳代。2妊1産。自然妊娠で妊娠成立し、妊娠36週3日の胎児超音波検査で右CDHが疑われ、当院へ紹介となった。妊娠37週0日に当院を受診し、超音波検査で右胸腔内に腸管及び腎臓と考えられる実質臓器を認め、右肺は著明に圧排されており、右CDHが疑われた。MRIを施行した結果、右CDHを認め、ヘルニア裂孔は後側方に位置しており、Bochdalek孔ヘルニアと考えられた。右胸腔内には腸管の他、超音波検査で指摘された右腎臓の脱出を認め、胸部異所性腎合併右CDHと診断した。CDHの重症度の予測因子である肺胸郭断面積比は0.11、肺断面積児頭周囲長比は0.18であった。新生児治療を行うにあたり、妊娠38週3日に全身麻酔下で帝王切開術を施行した。出生体重3334gの女児を娩出し、臍帯動脈血pH7.233、Apgarスコアは1分値2点、5分値3点であった。出生直後に児は速やかに挿管され、NICUへ入室した。軽度の肺高血圧を認めたが、循環動態は安定しており、NICU入室後に高頻度振動換気を開始した。日齢1に胸腔鏡下横隔膜ヘルニア直接縫縮術を施行した。ヘルニアは有嚢性で小腸、大腸とともに右腎も胸腔内に脱出していたが、肺は成熟しており、分葉も認めた。術後経過良好にて日齢19に退院となった。Bochdalek孔ヘルニアにおいて胸部に腎嵌入を認めるのは、非常に稀であり、肺と腎は実質臓器であるため超音波で区別しにくく、出生前に診断される例は稀である。今回、我々は超音波及びMRIを用いることによって、出生前に胸部異所性腎合併右CDHを診断でき、出生後速やかに新生児治療を行えた症例を経験した。(著者抄録)

インスリン療法中の患者の血糖変動は大きく、血糖自己測定を行わない時間帯の血糖値および、血糖変動傾向などの把握が困難で高血糖や低血糖に対する事前の対策の困難さが臨床的な問題である。持続血糖測定(CGM)は、昨今見過ごされていた高血糖や低血糖などの血糖変動を視覚化でき、とりわけ妊娠期間中はCGMを用いると母体の血糖変動が改善し、母児の周産期合併症の発症リスクも減少させることが報告されている。本稿では持続血糖測定とデータの見方、今後の見通しについて解説する。(著者抄録)

＜文献概要＞はじめに 産科医療補償制度の再発防止に関する報告書では,超緊急対応を要する妊産婦緊急疾患[常位胎盤早期剥離(以下,早剥)・臍帯脱出・子宮破裂・産後大出血・妊婦の意識障害]は,母体蘇生をできる限り迅速に行い,児娩出までをいかに短縮できるかが重要であるとし,各地域の院内整備や搬送体制の構築を最優先事項に挙げている。また,妊産婦死亡の約50%が防ぎ得たとされており,医療システムや情報の不備が影響を与えているという。本邦では,周産期医療施設が点在しているにも関わらず,緊急搬送を要する妊婦の情報共有を補うシステムが存在しない。その対策としてわれわれは,暗号化されたインターネット回線を利用して妊産婦の情報共有を効果的・効率的に行い,緊急搬送をサポートするための搬送補助システムを発案し「iPicss(アイピクス)」と名付けた。iPicssは,パイロットスタディで実地運用につながる結果を得た後,2018〜2020年度の地域医療介護総合確保基金(医療分)を用いて,2019年5月7日より岡山県の全分娩取り扱い施設で導入されている。近年,各分娩取り扱い施設からの周産期関連の搬送に関し,救急隊との情報連携方法が存在しないため,超緊急搬送事例において,救急隊が行う搬送対応に時間がかかるという話題が散見される。岡山県(以下,当県)では円滑な患者(母体と児)の搬送と病院間連携を目指すため,搬送元・搬送受入施設に加え,消防本部や出動する救急隊共にiPicssを用いて情報共有を行う方針として,来年度からのシステム運用の拡大に向け協議中である。また,災害時に分娩取り扱い施設から当県小児周産期リエゾンへ被災状況を報告するシステムの構築も必要であり,この部分にiPicssを流用し連携することにも取り組んでいる。2019年9月28日,当県北部(津山市)を震源域とする地震を想定した訓練を実施した。本稿では訓練を通して見えた課題についても報告する。

今日、世界的に帝王切開率は上昇傾向にあるため、世界保健機関は帝王切開術が施行された症例を分娩歴、分娩開始、胎位、胎数、妊娠週数により10グループに分類するRobson分類を用いて検討することを推奨している。今回、当院の帝王切開症例をRobson分類を用いて当院の帝王切開症例の特徴および適応症例の妥当性評価を検討したので報告する。2013年から2017年に当院で分娩した1933例を対象とした。Robson分類に従って分類し、各グループの帝王切開数及び帝王切開率を後方視的に検討した。本研究は、本学の倫理委員会の承認を得て施行された。5年間における当院の帝王切開率は全体で36.3%(702/1933例)であり、既往帝王切開症例(グループ5)の帝王切開数が最も多く206例であり、全帝王切開症例の29.3%を占めていた。グループ1とグループ2を合計したTSCN(term、single、cephalic、nulliparous)の帝王切開数は185例と全帝王切開症例の26.4%であり、2番目に多く、グループ2の中で予定帝王切開術となった症例は子宮手術歴、前置胎盤、胎児疾患の順に多かった。当院では、既往帝王切開症例及びTSCN症例の帝王切開数が全分娩件数に占める割合が高い。国内の既存の報告と比較検討すると、当院では正期産、単胎、頭位の妊婦での予定帝王切開率が高かった。帝王切開後経腟分娩の適応症例及びTSCN症例への帝王切開術の適応をより慎重に行うことによって、帝王切開率を改善することが期待できるのではないかと考えられた。Robson分類は、当院における帝王切開症例の分類ごとの数や比率を把握することができ、問題点を抽出し、改善点を検討することができることに関して有用であった。また、今後施設間のRobson分類による帝王切開症例の比較検討を行うことにより施設や地域ごとの特性を知り、地域ごとの医療水準の向上に繋がるツールになることが期待できる。(著者抄録)

[目的]分娩時血糖の動向をリアルタイムContinuous Glucose Monitoring(CGM)で評価し、分娩中における血糖動態を解明する。またAbnormal glucose tolerance(AGT)群とNormal glucose tolerance(NGT)群の平均血糖値(SG)を比較検討し、分娩時期による血糖値の差異から判明した結果をもとに分娩時の血糖管理法を選定する。[方法]検討期間に当院で経腟分娩を施行したAGT群:18例、NGT群:22例。ガイドライン並び、当院の管理指針を用い、必要時自由に飲食を摂り陣痛発来時から分娩期間を4段階(I期からIV期)に分け、分娩後48時間までの血糖変動をリアルタイムCGMで測定し解析。[結果]出生児背景に有意差無し。陣痛初来後のインスリン使用は、潜伏期と活動期で全症例のインスリン合計使用量は29単位から6単位へ減少。産後の使用無し。次にSGの分割プロットデザインの分散分析の結果、SGは分娩期間の主効果には有意差が認められたが[F(2.1,80.7)=5.915,P<0.01]耐糖能異常の有無の主効果、および期間と耐糖能異常の交互作用は認められなかった。T検定(ボンフェローニ法による修正)を用いた下位検定では、分娩期間別では4期の耐糖能異常の有無間(P<0.05)に有意差を認めた。耐糖能異常有無別の検討では、NGT群で3期と4期(P<0.05)に有意差を認めた。[結論]2群間比較からSGに差が認めず、児娩出後早期のSGが最大値を示した。その後NGT群のSGはAGT群に比し急峻に正常化することが示された、AGT群の分娩管理は絶食状態・補液・インスリン持続投与が現在推奨されるが、血糖測定下であれば正常群と同様の管理方法を用いて分娩を行うことが可能であるかもしれない。(著者抄録)

岡山県内の超緊急搬送例の時間短縮に向け、とりわけ高次医療施設以外で発症した常位胎盤早期剥離(早剥)例などの超緊急症例を円滑に搬送・院内連携するための新システムとしてOKAYAMA Picss(OP)を構築し県下で導入した。さらに安全性を備えた搬送の効率化を目指すため、2017年4月にインターネット回線を利用しOPをサポートするための搬送補助アプリシステムを発案しiPicssと名付けた。本報告ではOPを用いることで得られた有用性の検証を行った。検討1)県下周産期母子医療センター6施設で2011年1月〜2016年12月に搬送された搬送早剥例を後方視的に検討し、所要必要時間の現状を調査した。その結果、当院と比し、到着後娩出時間で有意に時間を必要とした。検討2)当院でのOP施行前後の超緊急搬送例の到着後児娩出までの所要時間の違いについて検討した。検討の結果、OP開始後は明らかに対応時間が短縮していた。検討3)他部署と合同研修会で行った周産期緊急シミュレーション内での旧OP(FAX使用)と新OP(iPicss使用)で所要時間の検証を行ったところ、iPicss利用時のほうにおいて圧倒的な時間短縮が認められた。また、OPとiPicssの実臨床現場での使用評価に関する質問紙調査を用い比較検討したところ、シート改変により見やすさが改善され、搬送受入施設は院内連携でiPicssを用いたOPは100%役立つという回答に改善された。また搬送元施設ではiPicss Appを用いた新OPは旧OPに比し使いやすいという回答が有意であった。

糖代謝異常合併妊娠の分娩は帝王切開率が高く、分娩停止などにより緊急帝王切開の可能性を念頭におく必要がある。分娩進行中や帝王切開時には食事摂取不能となり、手術や分娩によるストレスによりケトアシドーシスに陥りやすい。このため厳重な血糖管理が重要であるが、耐糖能異常合併妊娠の周術期の管理方法はいまだ確立されていないのが現状である。妊娠中の適切な血糖管理は周産期予後を向上し、周術期のリスクを軽減することから、糖尿病内科と協力して周産期管理を行うことが最も大切である。(著者抄録)

最近当科で経験した有嚢性横隔膜ヘルニア(CDH)の2例を報告する。【症例1】初産、38週3日、胎児心奇形を疑い当科に紹介受診し、超音波精査でCDH、完全口唇口蓋裂、及び総肺静脈還流異常症(TAPVC)が疑われた。MRI検査では横隔膜の挙上が認められた。肺胸郭断面積比は0.22-0.28であり他科との相談の上、経腟分娩可能と判断、39週3日2,552g、女児、AP-s 3/3点自然分娩で出生。46XX、dup(5)q31.1-q33.1部分トリソミー、出生後大動脈離断症(IAA)、心室中隔欠損(VSD)、卵円孔開存(PFO)、動脈管開存症(PDA)と診断。Stabilization後、日齢1、開腹下で縫縮術を施行、術後診断は左有嚢性CDHであった。日齢20、心臓手術施行、術後経過良好。現在経過観察中である。【症例2】1経妊1経産。在胎9週3日多発性海綿状血管腫合併妊娠のため、当科紹介受診。その後FGR傾向が認められたが、明らかな胎児異常は認められず、38週3日母体適応による選択的帝王切開を施行。2,400g、女児、AP-s 8/8点、出生後呼吸状態が悪化し挿管となった。胸部CT検査で原因不明の左横隔膜挙上と左肺虚脱を認め、左横隔膜弛緩症が疑われ、日齢0、当院NICU入院。日齢2、胸腔鏡下で縫縮術を施行。術後診断は有嚢性CDHであった。経過良好で退院。【考察】高率で他の先天異常を合併し、出生後治療に向け画像検査で正確な評価が必要となるCDHに対し、予後判定に有用な指標が確立されつつある。症例1はその予後判定を行い、経腟分娩を選択し生児を得た後、CDH縫縮術及び心臓手術を無事施行できた。出生前診断が困難であったCDH単独発症の1例と併せ文献的考察を絡め報告する。(著者抄録)

今回我々は、鉄剤不応性貧血を認めるラオス人妊婦において、子宮内胎児発育不全(Fetal Growth Restriction、以下FGRと略す)の精査を契機に血色素異常症を疑い、遺伝子診断に至った症例を経験した。【症例】32歳、ラオス人妊婦。2経妊1経産。前回妊娠は、無脳児にて人工中絶施行。妊娠初期検査にてHb10.5g/dl、MCV58.3fl、RBC506×10^4/μlと小球性低色素性貧血が認められ、家庭医療科で妊婦健診中、鉄剤反復処方を受けた。妊娠19週当科紹介、FGR(-1.7SD)が認められた。妊娠25週時、鉄剤不応性貧血を認め、FGR原因検索のために行ったHbA1c測定で異常低値。溶血性貧血鑑別のために行った間接Coombs試験で陽性、赤血球塗抹標本でtarget cellが認められた。さらにHbF測定で異常高値を認めたため、血色素異常症合併妊娠を強く疑い、妊娠25週時に精査入院となった。グリコヘモグロビン解析でHbA2、HbFが正常型の集積とは明らかに異なる分布を認め、血色素異常症と診断し、HbE症が疑われた。その際母児の重症化が起こりうるHbE症及びβサラセミア症の合併が心配されたが、入院後、安静管理にて胎児推定体重は-1.1SD程度まで改善し、母体のHb値も改善が認められたため妊娠29週時に退院となった。妊娠40週4日経腟分娩にて女児出生。出生体重は2584g(10パーセンタイル以下)、アプガールスコア10/10(1分/5分)であった。分娩後に行われた遺伝子検査によりHbE症ホモ接合体と診断された。近年、国際結婚率の増加によって、本症を認める機会が増える可能性が示唆され、本例において診断の過程で行ったHbF検査が、遺伝子診断を待たずに本症を疑う一助となることが示唆された。(著者抄録)
