RESUMO
A 35-year-old woman (gravida 1, para 0) was admitted to our hospital at 28 weeks' gestation with vaginal bleeding from placenta previa. Severe fetal bradycardia was observed during fetal heart rate monitoring. Ultrasonography showed widely dilated veins on the fetal surface of the placenta and an extraordinarily low umbilical artery peak systolic velocity in the Doppler study. Umbilical cord torsion was suspected. On the subsequent day, we performed a cesarean section due to worsening fetal heart rate patterns. Umbilical artery blood gas analysis indicated severe acidemia (pH 7.063), and umbilical cord torsion was confirmed at the placental cord insertion site. Diagnosing UCT prenatally is challenging; however, it can be suspected by scanning for the widely dilated veins on the fetal placental surface, termed as the "Sunset Sign," an abnormally low umbilical artery peak systolic velocity, and other fetal Doppler abnormalities.
RESUMO
Retroperitoneal ectopic pregnancies are extremely rare; only a few cases having been reported. Here, we report laparoscopic removal of an asymptomatic retroperitoneal ectopic pregnancy from a 29-year-old woman who was referred to our hospital for a suspected ectopic pregnancy. Transvaginal ultrasound did not reveal a gestational sac in the uterus or pelvic cavity. However, abdominal contrast-enhanced computer tomography showed a gestational sac between the abdominal aorta and inferior vena cava. On laparoscopy, the gestational sac was confirmed to be in this retroperitoneal location and successfully removed with minimal bleeding. Histopathologic examination revealed chorionic villi surrounded by lymphatic tissue, suggesting lymphatic spread of the retroperitoneal ectopic pregnancy. In summary, contrast-enhanced computer tomography is very useful for locating the site of pregnancy in women suspected of having a retroperitoneal ectopic pregnancy. Timely diagnosis of a retroperitoneal ectopic pregnancy before bleeding occurs can enable their safe laparoscopic removal.

AIM: In Japan, unlike Western countries, tocolytic agents are administered in long-term protocols to treat threatened preterm labor. Evaluating the side effects of this practice is crucial. We examined whether ritodrine hydrochloride had been administered in cases of maternal death, aiming to investigate any relationship between ritodrine administration and maternal death. METHODS: This retrospective cohort study used reports of maternal deaths from multiple institutions in Japan between 2010 and 2020. Data on the reported cases were retrospectively analyzed, and data on the route of administration, administered dose, and clinical findings, including causes of maternal death, were extracted. The amount of tocolytic agents was compared between maternal deaths with ritodrine administration and those without. RESULTS: A total of 390 maternal deaths were reported to the Maternal Death Exploratory Committee in Japan during the study period. Ritodrine hydrochloride was administered in 32 of these cases. The frequencies (n) and median doses (range) of oral or intravenous ritodrine hydrochloride were 34.4% (11) and 945 (5-2100) mg and 84.4% (27) and 4032 (50-18 680) mg, respectively. Frequencies of perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema as causes of maternal death were significantly higher with ritodrine administration than without it. CONCLUSIONS: Our results suggest a relationship between long-term administration of ritodrine hydrochloride and an increased risk of maternal death due to perinatal cardiomyopathy, cerebral hemorrhage, diabetic ketoacidosis, and pulmonary edema. In cases where ritodrine should be administered to prevent preterm labor, careful management and monitoring of maternal symptoms are required.

AIM: In Japan, noninvasive prenatal testing (NIPT) has been performed by facilities accredited by the Japanese Society of Obstetrics and Gynecology since 2013. However, since 2016, with the implementation of NIPT, which can only be performed by blood sampling, non-obstetricians have been involved in prenatal testing. Therefore, in July 2022, a new government-involved NIPT certification system based on Health Sciences Council guidelines was introduced to ensure access to prenatal testing information for pregnant women. METHODS: This survey was conducted in February 2023 and was the first survey after the certification system implementation. We conducted a web-based survey of 1227 pregnant women and nursing mothers who underwent NIPT after July 2022 to evaluate their experiences. RESULTS: Respondents were categorized by certification status as certified (C: 56%), non-certified (non-C: 23%), or uncertain (Q: 20%). The C group with a higher mean age at examination (35.0 ± 4.5 years) paid lower examination fees, received longer pre- and post-examination explanations, and underwent more weekday examinations (80%) than the other groups. Most respondents, 67%, 48%, and 53% in the C, non-C, and Q groups, respectively (p < 0.0001), stated that "NIPT needs to be regulated by the government or academic societies." The non-C group was more likely to say, "Insufficient post-test explanations at the laboratory made me more anxious," than the other groups when the testing results were non-negative (p = 0.015). CONCLUSIONS: Despite government regulation, some pregnant women choose convenience over certified facilities, risking inadequate care. The government should ensure that NIPT is a safe option for all pregnant women.
RESUMO
PURPOSE: To clarify whether maternal oxygen administration during vaginal delivery improves umbilical artery (UA) gas measurements and neonatal outcomes. METHODS: Singleton pregnancies requiring operative vaginal delivery or emergency cesarean section (CS) due to non-reassuring fetal status (NRFS) during vaginal delivery at our hospital from 2018 to 2021 were retrospectively investigated. Intrapartum fetal wellbeing was evaluated based on the 5-tier fetal heart rate (FHR) pattern which is a delivery management method widely used in Japan. Operative vaginal deliveries or emergency CS was performed under integrated judgment in NRFS. Patients were divided into the oxygen group to whom oxygen (10 L/min) was supplied by a facemask and the room air group. The UA gas measurements and neonatal outcomes were compared. The oxygen administration was classified by conditions before and after the coronavirus disease 2019 pandemic. As a secondary evaluation, stratification of FHR pattern levels and factors associated with UA pH < 7.15 were examined. RESULTS: A total of 250 patients required obstetric surgical delivery due to NRFS, including 140 (56%) and 110 (44%) in the oxygen and room air groups, respectively. No differences in maternal background factors were found between both groups, except for maternal age. UA gas measurements and neonatal outcomes also showed no significant differences. No significant factors were extracted in the multivariate analysis for UA pH < 7.15. CONCLUSIONS: Trans-maternal oxygen administration for intrapartum NRFS did not affect neonatal cord blood gasses or neonatal outcomes. Thus, routine oxygen administration for intrapartum NRFS may not always be necessary.

BACKGROUND: We investigated the utility of a molecular classifier tool and genetic alterations for predicting prognosis in Japanese patients with endometrial cancer. METHODS: A total of 1029 patients with endometrial cancer from two independent cohorts were classified into four molecular subtype groups. The primary and secondary endpoints were relapse-free survival (RFS) and overall survival (OS), respectively. RESULTS: Among the 265 patients who underwent initial surgery, classified according to immunohistochemistry, patients with DNA polymerase epsilon exonuclease domain mutation had an excellent prognosis (RFS and OS), patients with no specific molecular profile (NSMP) and mismatch repair protein deficiency had an intermediate prognosis, and those with protein 53 abnormal expression (p53abn) had the worst prognosis (P < 0.001). In the NSMP group, mutant KRAS and wild-type ARID1A were associated with significantly poorer 5-year RFS (41.2%) than other genomic characteristics (P < 0.001). The distribution of the subtypes differed significantly between patients with recurrence/progression and classified by sequencing (n = 764) and patients who underwent initial surgery (P < 0.001). Among patients with recurrence/progression, 51.4% had the opportunity to receive molecular targeted therapy. CONCLUSIONS: A molecular classifier is a useful tool for determining prognosis and eligibility for molecularly targeted therapy in patients with endometrial cancer.

BACKGROUND: For women diagnosed with hereditary breast and ovarian cancer, the clinical guidelines recommend risk-reducing salpingo-oophorectomy at age 35-40 years or after completion of childbearing. However, there is limited information regarding the current status of risk-reducing salpingo-oophorectomy in Japan. METHODS: To clarify factors influencing decision-making for risk-reducing salpingo-oophorectomy among Japanese women diagnosed with hereditary breast and ovarian cancer and their clinical outcomes, we analyzed the medical records of 157 Japanese women with germline BRCA pathogenic variants (BRCA1 n = 85, BRCA2 n = 71 and both n = 1) at our institution during 2011-21. Specimens obtained from risk-reducing salpingo-oophorectomy were histologically examined according to the sectioning and extensively examining the fimbriated end protocol. RESULTS: The risk-reducing salpingo-oophorectomy uptake rate was 42.7% (67/157). The median age at risk-reducing salpingo-oophorectomy was 47 years. Older age, married state and parity were significantly associated with risk-reducing salpingo-oophorectomy (P < 0.001, P = 0.002 and P = 0.04, respectively). History of breast cancer or family history of ovarian cancer did not reach statistical significance (P = 0.18 and P = 0.14, respectively). Multivariate analyses revealed that older age (≥45 years) and married state may be independent factors associated with risk-reducing salpingo-oophorectomy. Interestingly, the annual number of risk-reducing salpingo-oophorectomy peaked in 2016-17 and has increased again since 2020. The rate of occult cancers at risk-reducing salpingo-oophorectomy was 4.5% (3/67): ovarian cancer (n = 2) and serous tubal intraepithelial carcinoma (n = 1). CONCLUSION: Age and marital status significantly affected decision-making for risk-reducing salpingo-oophorectomy. This is the first study to suggest possible effects of Angelina Jolie's risk-reducing salpingo-oophorectomy in 2015 and the National Health Insurance introduced for risk-reducing salpingo-oophorectomy in 2020. The presence of occult cancers at risk-reducing salpingo-oophorectomy supports clinical guidelines recommending risk-reducing salpingo-oophorectomy at younger ages.

BACKGROUND: mRNA vaccination is an effective, safe, and widespread strategy for protecting pregnant women against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, information on factors such as perinatal outcomes, safety, and coverage of mRNA vaccinations among pregnant women is limited in Japan. Therefore, this study aimed to investigate the perinatal outcomes, coverage, adverse effects, and short-term safety of mRNA vaccination as well as vaccine hesitancy among pregnant women. METHODS: We conducted a multicenter online survey of postpartum women who delivered their offspring at 15 institutions around Tokyo from October 2021 to March 2022. Postpartum women were divided into vaccinated and unvaccinated groups. Perinatal outcomes, COVID-19 prevalence, and disease severity were compared between the two groups. Adverse reactions in the vaccinated group and the reasons for being unvaccinated were also investigated retrospectively. RESULTS: A total of 1,051 eligible postpartum women were included. Of these, 834 (79.4%) had received an mRNA vaccine, while 217 (20.6%) had not, mainly due to concerns about the effect of vaccination on the fetus. Vaccination did not increase the incidence of adverse perinatal outcomes, including fetal morphological abnormalities. The vaccinated group demonstrated low COVID-19 morbidity and severity. In the vaccinated group, the preterm birth rate, cesarean section rate, and COVID-19 incidence were 7.2%, 33.2%, and 3.3%, respectively, compared with the 13.7%, 42.2%, and 7.8% in the unvaccinated group, respectively. Almost no serious adverse reactions were associated with vaccination. CONCLUSIONS: mRNA vaccines did not demonstrate any adverse effects pertaining to short-term perinatal outcomes and might have prevented SARS-CoV-2 infection or reduced COVID-19 severity. Concerns regarding the safety of the vaccine in relation to the fetus and the mother were the main reasons that prevented pregnant women from being vaccinated. To resolve concerns, it is necessary to conduct further research to confirm not only the short-term safety but also the long-term safety of mRNA vaccines.

OBJECTIVE: Optimal adjuvant chemotherapy for nonsquamous cervical carcinoma has not yet been established. This study investigated the efficacy and safety of docetaxel/carboplatin (DC) for early-stage nonsquamous cell cervical carcinoma after radical hysterectomy (RH). METHODS: We evaluated 157 patients with stage IB-IIB nonsquamous cervical carcinoma with intermediate risk and high risk treated at our institution with DC after type II or III RH from 2007 to 2021. Patients received docetaxel (60-70 mg/m2) and carboplatin (area under the curve 5-6) every 3 weeks for six cycles. The primary endpoint was 2 year recurrence-free survival (RFS) and the secondary endpoint was adverse events (AEs). RESULTS: There were 106 intermediate-risk and 51 high-risk patients. The high-risk patients included 11 with positive parametrial involvement, 20 with pelvic lymph node metastases, and 20 with both parametrial involvement and pelvic lymph node metastases. The 2 year RFS rates for intermediate-risk, high-risk, and positive pelvic lymph nodes were 94.8% (95% confidence interval [CI], 87.9-97.8), 80.1% (95% CI, 64.1-89.5), and 74.5% (95% CI, 55.4-86.4), respectively. Sixteen patients had recurrence, including local recurrence (n = 6), distant metastasis (n = 9), and local and distant metastasis (n = 1). Hematologic toxicity was the most frequent AE, especially leukopenia and neutropenia. Nausea and constipation were the most frequent nonhematologic toxicities. CONCLUSION: DC therapy at our institution showed good 2 year RFS, and postoperative adjuvant therapy with DC therapy is suggested as a useful strategy for patients with nonsquamous cervical carcinoma.

AIM: To investigate whether the early initiation of neuraxial analgesia prolongs the duration of electively induced labor in Japanese multiparous women. METHODS: This retrospective study included multiparous term women who underwent elective induction of labor using combined spinal-epidural analgesia at the Showa University Hospital between October 2018 and March 2021. The participants were divided into two groups: early and late. If neuraxial analgesia was initiated when the cervical dilation was ≤3 cm, the patient was included in the early group. The remaining patients were included in the late group. The obstetric and neonatal outcomes were compared between the two groups. The primary outcome was the duration of delivery. The secondary outcomes were the rates of instrumental and cesarean deliveries. RESULTS: Two hundred and ninety-seven women (early group = 139, late group = 158) were included in the analysis. The duration of the first stage of labor did not differ significantly between the early and late groups (median: 232 vs. 260 min, p = 0.35). Similarly, there was no significant difference in the duration of the second stage (37 vs. 40 min, p = 0.20). Moreover, the rates of instrumental and cesarean deliveries did not differ significantly between the groups, and the neonatal outcomes were comparable. CONCLUSION: Early initiation of neuraxial analgesia in the elective induction of parous Japanese women did not prolong the duration of delivery. Our results suggest that neuraxial analgesia may be initiated whenever a parturient desires it.

Here, we aimed to provide an overview of Japan Council for the Implementation of the Maternal Emergency Life-Saving System (J-CIMELS) and its simulation program, which has reduced maternal mortality due to direct causes in Japan. The Japan Association of Obstetricians and Gynecologists (JAOG), Japan Association of Obstetricians and Gynecologists, and Maternal Death Exploratory Committee (JMDEC) launched the Maternal Death Reporting Project in 2010. The project analyzed obstetricians' tendency to delay their initial response to sudden maternal deterioration. Obstetricians can predict small changes before deterioration by monitoring vital signs. In 2015, the J-CIMELS was established to provide practical education. J-CIMELS developed a simulation program (J-MELS; Japan Maternal Emergency Life Support) to ensure that the obstetricians acquire the latest knowledge of emergency physicians, anesthesiologists, and other general practitioners and apply it in clinical situations. In the last 7 years, the J-MELS basic course has been conducted 1000 times with a total attendance of 19 890 people. As a result, the incidence of obstetric hemorrhage progressively decreased from 29% in 2010 to 7% in 2020. We believe that the activities of J-CIMELS are improving obstetric care providers' medical practices in Japan.

BACKGROUND: Human papillomavirus (HPV) type 67 is phylogenetically classified into Alphapapillomavirus species 9 (alpha-9) together with other carcinogenic types (HPV16, 31, 33, 35, 52 and 58), but is the only alpha-9 type defined as possibly carcinogenic. This study aimed to determine whole-genome sequences of HPV67 isolated from Japanese women with cervical cancer or cervical intraepithelial neoplasia (CIN) to better understand the genetic basis of the oncogenic potential of HPV67. METHODS: Total cellular DNA isolated from cervical exfoliated cells that were single positive for HPV67 (invasive cervical cancer, n = 2; CIN3, n = 6; CIN 2, n = 1; CIN1, n = 2; the normal cervix, n = 1) was subjected to PCR to amplify HPV67 DNA, followed by next generation sequencing to determine the complete viral genome sequences. Variant lineages/sublineages were assigned through viral whole-genome phylogenetic analysis. The transcriptional activity of the virus early promoter was assessed by luciferase reporter assays in cervical cancer cell lines. RESULTS: Phylogenetic analyses of HPV67 genomes from Japan (n = 12) revealed that 11 belonged to lineage A (sublineage A1, n = 9; sublineage A2, n = 2) and one belonged to lineage B. All cancer cases contained sublineage A1 variants, and one of these contained an in-frame deletion in the E2 gene. The long control region of the HPV67 genome did not induce transcription from the virus early promoter in HeLa cells, but showed weak transcriptional activity in CaSki cells. CONCLUSIONS: The single detection of HPV67 in cervical cancer and precancer specimens strongly suggests the carcinogenic potential of this rare genotype. The phylogenetic analysis indicates a predominance of lineage A variants among HPV67 infections in Japan. Since only 23 complete genome sequences of HPV67 had been obtained until now, the newly determined genome sequences in this study are expected to contribute to further functional and evolutionary studies on the genetic diversity of HPV67.

Advances in perinatal care have improved the prognoses of both mothers and neonates; however, cerebral palsy continues to occur. In this study, we examined methods for the intragestational evaluation of the health of infants who later developed cerebral palsy. A retrospective review was conducted on light-for-dates cases among the 2113 cause analysis reports issued by the Japan Obstetric Compensation System between January 2009 and September 2018. In our examination, we determined that non-stress tests and ultrasonic Doppler tests were used to evaluate fetal well-being. Moreover, we observed cases in which additional testing was not performed even when fetal growth restriction (FGR) was identified. Appropriate management of FGR may help reduce the incidence of cerebral palsy.

AIM: This study aimed to assess the utility of ultrasound screening for pregnancies with positive noninvasive prenatal testing results for trisomy 21, trisomy 18, and trisomy 13. METHODS: We performed a retrospective analysis of positive noninvasive prenatal testing results and first-trimester ultrasound screening at our department between 2013 and 2019. Invasive genetic testing was performed if the patient had positive noninvasive prenatal testing results. Fetal ultrasound and cytogenetic data were collected. Noninvasive prenatal testing was performed in the women for advanced maternal age, nuchal translucency thickness, or history of abnormality in the previous child or relative. RESULTS: Forty-one pregnant women had positive noninvasive prenatal testing results for trisomy 21, trisomy 18, and trisomy 13. Twenty-three women had positive results for trisomy 21, 13 had positive results for trisomy 18, and 5 had positive results for trisomy 13 at 11 to 14 weeks of gestation. The positive predictive value of noninvasive prenatal testing was 100% for trisomy 21, 84.6% for trisomy 18, and 100% for trisomy 13. The positive predictive value of positive noninvasive prenatal testing results and fetal morphological abnormalities was 100% for trisomy 21, trisomy 18, and trisomy 13. CONCLUSION: Combining an ultrasound examination with noninvasive prenatal testing resulted in a higher positive predictive value for trisomy 18. Normal ultrasound examination results can help alleviate stress caused by false-positive noninvasive prenatal testing results. In contrast, the positive predictive value and negative predictive value for trisomy 21 were not altered by adding an ultrasound examination to noninvasive prenatal testing.

Kagami-Ogata syndrome (KOS14) is a rare disease characterized by omphalocele, polyhydramnios and a bell-shaped thorax. Although the coat-hanger appearance of the ribs on postnatal X-rays is a key diagnostic finding of KOS14, its prenatal diagnosis remains challenging. We encountered a case of KOS14 diagnosed prenatally that showed omphalocele, polyhydramnios, and a bell-shaped narrow thorax. The coat-hanger angle (CHA) measured at the sixth thoracic vertebrae and the ribs using three-dimensional (3D) ultrasonography was 39°, reflecting the coat-hanger appearance of the ribs. Segmental uniparental disomy chromosome 14 (UPD(14)pat) was confirmed by a methylation analysis and microsatellite analysis after birth. The median CHA (minimum, maximum) in 25 normal fetuses was 19 (9, 26) degrees, and a sonographic CHA of 30° may be a border value for diagnosing KOS14. When the combination of omphalocele and polyhydramnios is found prenatally, 3D ultrasonography for CHA might aid in the differential diagnosis of KOS14.

PURPOSE: To analyze the long-term prognosis of primary and secondary fetal pleural effusion (FPE). METHODS: We investigated all cases of FPE in a single University hospital (2005-2020). Cases were classified as primary (cases with only pleural effusion) and secondary (cases with other abnormalities such as chromosomal abnormalities or fetal cardiac failure). We retrospectively reviewed the medical records from the time of diagnosis, to assess medical procedures performed, chromosomal test results, and clinical outcomes. RESULTS: Among 18 027 deliveries, 17 FPEs were identified (primary FPE: 8, secondary FPE: 9). Most primary FPEs were diagnosed in the second trimester of pregnancy, while all secondary FPEs were diagnosed in the third trimester. Secondary FPE was often associated with chromosomal abnormalities, including trisomy 21. The prognosis of pleural effusion caused by trisomy 21 was relatively good, except for cases with TAM. Cases of secondary FPE without trisomy 21 were of cardiac origin, and the neonatal prognosis was poor. The short-term prognosis was better in the primary FPE group, but long-term follow-up identified conditions such as acute encephalitis with refractory, repetitive partial seizures, developmental delay and attention deficit hyperactivity disorder. CONCLUSION: Fetal pleural effusion without the presence of chromosomal abnormalities or morphologies has a good short-term prognosis, but the long-term prognosis is poor. Thus, long-term follow-up is necessary for all cases of fetal pleural effusion.

Non-invasive prenatal testing (NIPT) is used worldwide to screen for fetal aneuploidy. Although previous studies on the psychosocial aspects of NIPT have focused on satisfaction regarding the test, we surveyed women who experienced negative emotions after receiving NIPT. From January 2018 to March 2019, we surveyed pregnant women whose NIPT results were negative, one year after the test. Of the 526 respondents, 35 (6.7%) regretted receiving NIPT and blamed themselves for taking it. We assigned this 6.7% of respondents to the negative emotion group. Although, 76.5% of the participants in the negative emotion group reported they would like to take NIPT for their next pregnancy, it was significantly lower as compared to the control group (92%). Furthermore, 31.9% of respondents in the control group reported that they would recommend similar tests to their relatives and friends. Conversely, in the negative emotion group, this proportion was lower at 17.1%. This suggests that guilt over testing may be meaningful. Thus, this study showed that some NIPT examinees regretted taking the test and blamed themselves. Respondents reported experiencing stress, anxiety, and depression even before NIPT affirming that it is important to address pregnant women's psychosocial status during pre-test genetic counseling.

BACKGROUND: Few reports have presented an overall view of pregnant women with coronavirus disease 2019 (COVID-19) across an entire country and throughout the entire gestation period. Furthermore, no such reports are available for Japan. We examined the clinical characteristics and outcomes of pregnant women with COVID19 on a national scale in Japan. METHODS: A nationwide questionnaire-based survey for all 2,185 maternity services in Japan was conducted between July and August 2020. Information regarding maternal characteristics and epidemiological, clinical, treatment, and perinatal outcomes of pregnant women diagnosed with COVID-19 between 16 January and 30 June 2020 were collected. Main outcome measures were incidence of pregnant women with COVID-19 and infant infection, positive rate of the universal screening test for asymptomatic pregnant women, identification of infection route and rates of maternal death, and severe cases. RESULTS: Responses from 1,418 institutions were assessed (65% of all delivery institutions in Japan). Seventy-two pregnant women were reported to have been diagnosed with COVID-19. The positive rate of the universal screening test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among asymptomatic pregnant women was 0.03% (2/7428). The most common route of infection was familial (57%). Fifty-eight pregnant women with COVID-19 were symptomatic, of whom five (8.6%) had a severe infection and one died (a tourist). Severe respiratory symptoms, oxygen administration, and pneumonia were frequently reported in the third trimester and postpartum period compared with in early pregnancy (22.2% vs 2.5% [P = 0.03], 38.9% vs 7.5% [P = 0.01], and 50.0% vs 7.5% [P < 0.001], respectively). All pregnant women with COVID-19 underwent caesarean sections, regardless of symptoms. There were no SARS-CoV-2 transmissions to newborns. CONCLUSIONS: In Japan, the number of cases of COVID-19 infection in pregnant women is very low. Compared with early pregnancy, late pregnancy may be a risk factor for exacerbation of symptoms and familial transmission is the most common route of infection. The importance of infection prevention should be emphasised, especially in women in late pregnancy, their families, and any cohabitants.

BACKGROUND: Nationwide antenatal human T-cell leukemia/lymphoma virus type-1 (HTLV-1) antibody screening has been conducted in Japan. The purpose of our study was to clarify the issues related to feeding options to prevent postnatal mother-to-child transmission. METHODS: Of the pregnant carriers at 92 facilities in Japan between 2012 and 2015, 735 were followed prospectively. Among the children born to them, 313 (42.6%) children were followed up to the age of 3 and tested for HTLV-1 antibodies. The mother-to-child transmission rate was calculated for each feeding option selected before birth. RESULTS: Among the 313 pregnant carriers, 55.0, 35.1, 6.1, and 3.8% selected short-term breast-feeding (≤3 months), exclusive formula feeding, frozen-thawed breast-milk feeding, and longer-term breast-feeding, respectively. Despite short-term breast-feeding, 8-18% of the mothers continued breast-feeding for 4-6 months. The mother-to-child transmission rate with short-term breast-feeding was 2.3% (4/172), and its risk ratio compared with that of exclusive formula feeding was not significantly different (0.365; 95% CI: 0.116-1.145). Because of the small number of children who were fed by frozen-thawed breast-milk, their mother-to-child transmission rate was not statistically reliable. CONCLUSIONS: Pregnant HTLV-1 carriers tended to select short-term breast-feeding in Japan. While short-term breast-feeding was not always easy to wean within 3 months, it may be a viable option for preventing postnatal mother-to-child transmission because the vertical transmission rate with short-term breast-feeding was not significantly higher than that with exclusive formula feeding. Increasing the follow-up rates for children born to pregnant carriers may provide clearer evidence of preventative effects by short-term breast-feeding and frozen-thawed breast-milk feeding.

AIM: In Japan, dilatation and curettage (D&C) is a common procedure for spontaneous miscarriage and induced abortion, and its safety has long been an issue. Electric vacuum aspiration (EVA) is also common, but manual vacuum aspiration (MVA) was introduced recently, with medical abortions using mifepristone or misoprostol which are not yet legally accepted. This nationwide retrospective study surveyed the surgical methods and complications associated with spontaneous miscarriage and induced abortion at less than 12 weeks of gestation in Japan to assess their safety, in comparison with a similar survey for induced abortions in 2012. METHODS: Questionnaires were sent to 4176 facilities with a license for induced abortion surgeries in 2019. The questions included were the methods used, number of spontaneous miscarriages and induced abortions, and number of complications (uterine perforation, incomplete abortion, and gross bleeding requiring blood transfusion). RESULTS: Responses were received from 1706 facilities (40.9%). Although EVA with sharp curettage was the most common surgical method, which was used for 11 953 spontaneous miscarriages (28.9%) and 24 045 induced abortions (37.3%), the most common surgical method per facility was D&C, and the rates of D&C for spontaneous miscarriages (38.4%) and induced abortions (44.7%) performed in general hospitals were significantly higher than those in clinics (24.1% and 22.0%, respectively). There was no significant difference in the complication incidence rate among surgical methods for spontaneous miscarriages. However, in induced abortion surgery, the total complication and incomplete abortion incidence rates for D&C were significantly higher than those for EVA without sharp curettage (47/15 162 [0.31%] vs. 29/18 693 [0.16%], p = 0.00362, 45/15 162 [0.30%] vs. 27/18 693 [0.14%], p = 0.00285, respectively). There was no significant difference in the complication incidence rate between MVA and other surgical methods for each abortion surgery. CONCLUSION: In Japan, especially in general hospitals, D&C is still widely used for miscarriage and induced abortion surgery. Its complication-incidence rates significantly decreased compared with that of the nationwide survey in 2012, but were still significantly higher than EVA without sharp curettage. Few facilities used MVA, but its complication rate was comparable with those of other surgical methods.
