RESUMEN
Our aim is to investigate the obstetric practices in Japan regarding the screening and management of gestational diabetes mellitus (GDM) diagnosed before 20 weeks of gestation (early-GDM). A web-based questionnaire survey was administered to 991 teaching hospitals between November 2021 and February 2022, and 602 responses were received (a response rate of 61%). Screening tests for all pregnant women in the first trimester were conducted in 553 (92%) hospitals, and nearly all of these hospitals (535/553 [97%]) adhered to an individual protocol, predominantly relying on random plasma glucose measurements (488/535 [91%]). A quarter (139 [26%]) implemented a risk profile assessment for GDM screening, taking into account factors such as previous gestational diabetes, prior macrosomia, and family history of diabetes. A small number (23 [4%]) targeted only women at high risk of GDM using the risk profile assessment. The majority of hospitals (501 [94%]) employed a 75 g oral glucose tolerance test as a diagnostic measure, and glycemic control for early-GDM was established in most hospitals (429 [80%]). Of the 535 hospitals that maintained an individual management protocol, 356 [67%] facilitated dietary management, self-monitoring of blood glucose, and insulin administration if needed to meet glycemic targets. Our survey revealed a widespread adoption of universal screening and subsequent treatment for early-GDM in Japan.
RESUMEN
AIM: In March 2021, the Japanese Ministry of Health, Labour and Welfare revised the optimal gestational weight gain standards. In this study, we examined whether this revision affected gestational weight gain and low birth weight rates. METHODS: We analyzed the records of singleton pregnant women who underwent checkups from their 1st trimester and delivered at our institute after 37 weeks between 2020 and 2021 (before the revision) and between 2022 and 2023 (after the revision). Pregnancy outcomes were assessed in the following four groups stratified by pre-pregnancy body mass index (BMI): underweight (BMI: <18.5 kg/m2), normal-weight (BMI: 18.5-24.9 kg/m2), overweight (BMI: 25-29.9 kg/m2), and obese (BMI: ≥30 kg/m2). Leaflets on the optimal gestational weight gain standards for each group were distributed to all pregnant women at the first prenatal checkup. RESULTS: In each group, gestational weight gain did not change before and after the revision, with the corresponding values of 10.8 kg and 11.1 kg in the underweight (p = 0.94), 10.7 kg and 10.4 kg in the normal weight (p = 0.14), 9.7 kg and 9.2 kg in the overweight (p = 0.32), and 7.4 kg and 6.7 kg in the obese (p = 0.44) groups. Furthermore, the prevalence of low birth weight did not decrease in all groups. CONCLUSIONS: No significant differences in gestational weight gain or low birth weight were observed after the revision of the 2021 gestational weight gain recommendations. Merely distributing leaflets to pregnant women may not be sufficient to improve gestational weight gain or reduce low birth weight rates.
RESUMEN
OBJECTIVE: This study aimed to clarify the maternal and neonatal outcomes based on the presence or absence of a Couvelaire uterus with placental abruption. METHODS: This single-center retrospective study was conducted at a tertiary perinatal center in Japan, including patients diagnosed with acute placental abruption who delivered live births via cesarean section between 2016 and 2023. Patients were divided into two groups based on the presence or absence of a Couvelaire uterus during surgery: the Couvelaire and normal uterus groups. Maternal and neonatal outcomes were assessed. RESULTS: This study included 76 patients: 24 in the Couvelaire group and 52 in the normal uterus group. No patients underwent hysterectomies. The Couvelaire group had significantly higher intraoperative blood loss (median 1152 vs 948 g, P = 0.010), blood transfusion rates (58% vs 31%, P = 0.022), fibrinogen administration rates (38% vs 13%, P = 0.038), intensive care unit/high care unit admission rates (29% vs 7.7%, P = 0.013), and disseminated intravascular coagulation complication rates (25% vs 7.7%, P = 0.038). There were no differences in birth weight, gestational age (median 2387 vs 2065 g, P = 0.082), Apgar score <4 at 5 min (4.2% vs 3.9%, P = 0.95), umbilical artery blood pH <7.1 (25% vs 22%, P = 0.82), and neonatal death (4.2% vs 1.9%, P = 0.57). CONCLUSION: A Couvelaire uterus indicated adverse maternal outcomes but not neonatal ones. Its presence necessitates preparation for blood transfusions and/or intensive patient follow-up.
RESUMEN
AIM: Cervical ripening is commonly performed before oxytocin administration during labor induction in pregnant women with an unfavorable cervix. In Japan, a controlled-release Dinoprostone vaginal insert (CR-DVI) was approved in 2020. Although many studies have compared the mechanical methods of ripening and prostaglandins, few have examined the impact of additional options for labor induction. This study aimed to assess the impact of CR-DVI as an additional option for labor induction in women with an unfavorable cervix. METHODS: In this single-center retrospective study conducted in Japan, 265 participants were divided into two groups: before (January 2018 to May 2020) and after (June 2020 to November 2022) CR-DVI introduction. Before CR-DVI was introduced, hygroscopic dilators were used for all cases instead. On the other hand, after the introduction of CR-DVI, the first choice for cervical ripening was CR-DVI. The CR-DVI was retained vaginally for up to 12 hours after insertion. However, if hyper-stimulation or non-reassuring fetal status was suspected, or if a new membrane rupture occurred, it was removed immediately according to the removal criteria. Oxytocin infusions were used during both periods if needed. We compared delivery and neonatal outcomes between the groups. RESULTS: The 265 participants were divided into two groups: before (n=116) and after (n=149) CR-DVI introduction. There were no significant differences in maternal characteristics except for the primiparous proportion. CR-DVI was used in 93% of cases after introduction. Hygroscopic dilators also continued to be used; however, their use decreased to about 34%. The vaginal delivery rate was significantly higher after the introduction of CR-DVI than before its introduction (50.9% vs. 66.4%; p=0.01). Multivariable analysis revealed a significantly higher rate of vaginal delivery after CR-DVI introduction. Of the 149 cases in which a CR-DVI was used, 111 (79.9%) were removed before 12 hours. There were no significant differences in neonatal outcomes. CONCLUSION: The rate of vaginal delivery was higher after CR-DVI introduction than before its introduction, and adverse pregnancy outcomes did not increase. Therefore, introducing CR-DVI as an option for labor induction may increase the probability of vaginal delivery. Safety can also be ensured by adhering to the removal criteria.
RESUMEN
Previous studies have shown that interpregnancy weight fluctuations impact perinatal outcomes. In order to examine this in Japanese women, we analyzed the data of 2,861 women in their first and second pregnancies who delivered singletons between 2000 and 2022. We compared the second pregnancy perinatal outcomes of women whose interpregnancy body mass index (BMI) change was -1 to 1 unit with those of women whose BMI change was < -1 or ≥ 1 unit. An interpregnancy BMI change ≥ 1 unit was associated with an increased risk of developing gestational diabetes mellitus (adjusted odds ratio [aOR], 1.51; 95% confidence interval [CI], 1.18-1.95) and delivering a large for gestational age neonate (aOR, 1.67; 95% CI, 1.15-2.42) but a decreased risk of preterm birth (aOR, 0.66; 95% CI, 0.46-0.95). An interpregnancy BMI change < -1 unit was associated with a decreased risk of developing gestational diabetes mellitus (aOR, 0.51; 95% CI, 0.31-0.85). In a subgroup analysis of three groups divided according to prepregnancy BMI, interpregnancy BMI changes ≥ 1 unit in women with a BMI of < 18.5 kg/m2 before their first pregnancy were associated with a remarkable risk reduction of developing preterm birth (aOR, 0.30; 95% CI, 0.11-0.81). Interpregnancy BMI changes < -1 unit in women with a BMI of ≥ 25 kg/m2 before their first pregnancy were associated with a remarkable risk reduction of developing gestational diabetes mellitus (aOR, 0.33; 95% CI, 0.12-0.88). Weight gain during interpregnancy period was related to an increased risk of gestational diabetes mellitus and delivery of a large-for-gestational-age neonate, whereas weight loss was related to a decreased risk of developing gestational diabetes mellitus. These results indicate the importance of interpregnancy weight control as part of preconception care; therefore, women considering additional pregnancies should be educated on the importance of maintaining a healthy weight.

AIM: This study aimed to determine the weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy body mass index (BMI) and make recommendations for optimal weight gain in Japan. METHODS: The Japan Society of Obstetrics and Gynecology perinatal database for 2015-2017 was used. From the 719 723 deliveries included in this database, parturients with underlying diseases or missing data were excluded, and 419 114 deliveries were analyzed. A questionnaire survey was also conducted to weigh each perinatal adverse event. For each of the nine outcomes, a restricted cubic spline model was made to estimate the association between the "expected gestational weight gain at 40 weeks" and the outcome risk. RESULTS: Since the classes of medical facilities were generally the same, weights were assigned according to the mean of the questionnaires rather than by the class of the facility. For each pre-pregnancy BMI, the weight gains during pregnancy that minimized the predicted probability of various adverse perinatal events were 12-15, 10-13, 7-10, and upper limit of 5 kg for the underweight, normal-weight, obese 1, and obese ≥2 groups, respectively. CONCLUSIONS: The weight gain during pregnancy that minimizes the predicted probability of various perinatal adverse events according to the pre-pregnancy BMI was established.

OBJECTIVE: The relationship between FMF and pregnancy outcomes remains unclear. This systematic review and meta-analysis aimed to clarify this association. METHODS: Electronic databases-PubMed, Web of Science, Cochrane, and EMBASE-were searched on 20 December 2022, using specific search terms. Case-control, cohort, and randomized clinical trial studies comparing patients with FMF and healthy controls were considered eligible. We excluded systematic reviews, meta-analyses, case series with fewer than five cases, republished articles without new findings on pregnancy outcomes, studies targeting paternal FMF, and those not published in English. The results were summarized in the form of odds ratios (ORs) and 95% CIs, using a random-effects model. This study was registered in the University hospital Medical Information Network Clinical Trials Registry (Japan) as UMIN000049827. RESULTS: The initial electronic search identified 611 records, of which 9 were included in this meta-analysis (177 735 pregnancies, 1242 with FMF, and 176 493 healthy controls). FMF was significantly associated with increased odds of preterm deliveries (OR, 1.67; 95% CI, 1.05-2.67; I2 = 22%) and insignificantly associated with increased odds of fetal growth restriction (OR, 1.45; 95% CI, 0.90-2.34; I2 = 0%) and hypertensive disorders during pregnancy (OR, 1.28; 95% CI, 0.87-1.87; I2 = 0%). CONCLUSION: FMF was significantly associated with preterm delivery and insignificantly associated with fetal growth restriction and hypertensive disorders. All of the included studies were observational studies. Treatment characteristics were not fully collected from the articles, and further analysis of treatments for FMF in pregnancy is still warranted.

AIM: In 2017, the American College of Cardiology (ACC) re-defined hypertension (HT) as follows: elevated blood pressure (EBP), systolic blood pressure (SBP) 120-129 mmHg and diastolic blood pressure (DBP) <80 mmHg; stage 1 HT, SBP 130-139 mmHg or DBP 80-89 mmHg; and stage 2 HT: SBP ≥140 mmHg or DBP ≥90 mmHg. It is well known that women with stage 2 HT are at higher risk of preeclampsia and have poorer pregnancy and delivery outcomes. While there are few reports on the risk in women with EBP and stage 1 HT, and none from Japan. This study aimed to determine whether women in Japan with EBP and stage 1 HT are at risk of preeclampsia. METHODS: In this single-center retrospective study conducted in Japan, subjects were classified into stage 2 HT, stage 1 HT, EBP, and normal groups based on blood pressure measurements at the time of the first visit before 20 weeks of gestation. Women with a diagnosis of hypertension made before pregnancy were classified into the stage 2 HT group. We compared pregnancy and delivery outcomes, such as preeclampsia, between groups. RESULTS: A total of 5129 cases (normal, n = 4283; EBP, n = 427; stage 1 HT, n = 303; stage 2 HT, n = 116) were included. Preeclampsia incidence rates were 2.7%, 5.6%, 10.6%, and 21.6%, respectively. The adjusted OR (95% CI) for preeclampsia incidence were 2.90 (1.81-4.66), 5.90 (3.87-9.20), and 13.80 (7.97-24.0), respectively. CONCLUSIONS: Women with EBP and stage 1 HT are at high risk of preeclampsia, similar to those with stage 2 HT.

In Japan, rubella antibodies are tested in all pregnant women to detect subclinical infections. This study aimed to assess the validity of measuring rubella antibodies for detecting subclinical rubella among pregnant women in Japan. This single-center retrospective study measured rubella hemagglutination inhibition (HI) titers and rubella-specific IgM antibody index (IgM) values. IgM values were measured by conducting enzyme immunoassay, and IgM-values >1.2 were considered positive. Of 14,965 included pregnant women, 186 (1.2%) were IgM-positive. Only one patient was clinically diagnosed with rubella (HI titer, 1:2,048; IgM value, 10) and developed fever and skin rash. She decided to terminate her pregnancy without undergoing repeated blood tests. Of the IgM-positive patients, 136 (73.1%) had rubella HI titers of < 1:256. The correlation coefficient between rubella HI and IgM titers was weakly positive (0.2527; P < 0.0001). This study showed that a single combination of rubella HI and rubella-specific IgM measurements alone could not detect subclinical rubella. Creating awareness among pregnant women by informing them that almost all rubella-specific IgM-positive individuals without symptoms are not acutely infected could decrease their anxiety and prevent unnecessary pregnancy termination.

Vitamin K deficiency can cause coagulopathy; therefore, supplementation is recommended to prevent intracranial hemorrhage in newborns. Some reports have shown that maternal vitamin K deficiency is associated with intracranial hemorrhage in the fetus. However, no clear guidelines exist for the diagnosis and treatment of maternal vitamin K deficiency to prevent fetal intracranial hemorrhage. We report a case of intrauterine fetal death due to intracranial hemorrhage associated with maternal vitamin K deficiency resulting from hyperemesis gravidarum. In this case, maternal protein induced by vitamin K absence II (PIVKA-II) was high at the time of intrauterine fetal death. Therefore, measuring maternal PIVKA-II levels in high-risk cases may help determine the timing of therapeutic interventions for vitamin K deficiency during pregnancy.
RESUMEN
BACKGROUND: Postpartum hemorrhage is the leading cause of maternal death and severe maternal morbidity worldwide. Previous studies have reported the importance of multidisciplinary treatment approaches for postpartum hemorrhage; however, only a few studies have shown a clear improvement in maternal outcomes. Therefore, this study aimed to investigate the efficacy of a call system for postpartum hemorrhage in a tertiary emergency facility for rapid multidisciplinary treatment and its effect on maternal outcomes. METHODS: This single-center retrospective cohort study included patients transferred to our hospital due to postpartum hemorrhage between April 1, 2013, and March 31, 2019. The primary outcome was mortality, and the secondary outcomes were morbidity (duration of hospital stay, duration of intensive care unit stay, admission to the intensive care unit, respirator use, duration of ventilator support, acute kidney injury, transfusion-associated circulatory overload/transfusion-related acute lung injury, hysterectomy, composite adverse events, blood transfusion initiation time, blood transfusion volume, and treatment for postpartum hemorrhage). An in-hospital call system implementation commenced on April 1, 2016. The study outcomes were compared 3 years before and after implementing the call system. RESULTS: The blood transfusion initiation time and duration of hospital stay were significantly shortened after implementing the call system for postpartum hemorrhage. No maternal deaths were observed after implementing the system. CONCLUSIONS: Implementing call systems specialized for postpartum hemorrhage in tertiary emergency facilities may improve maternal outcomes.

The Totten Glacier in East Antarctica, with an ice volume equivalent to >3.5 m of global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean forcing. Here, we use bathymetric and oceanographic observations from previously unsampled parts of the Totten continental shelf to reveal on-shelf warm water pathways defined by deep topographic features. Access of warm water to the Totten Ice Shelf (TIS) cavity is facilitated by a deep shelf break, a broad and deep depression on the shelf, a cyclonic circulation that carries warm water to the inner shelf, and deep troughs that provide direct access to the TIS cavity. The temperature of the warmest water reaching the TIS cavity varies by ~0.8 °C on an interannual timescale. Numerical simulations constrained by the updated bathymetry demonstrate that the deep troughs play a critical role in regulating ocean heat transport to the TIS cavity and the subsequent basal melt of the ice shelf.

Although extracorporeal membrane oxygenation is relatively contraindicated in patients with severe disseminated intravascular coagulation (DIC), it can be safely introduced by providing adequate anti-DIC therapy.
RESUMEN
INTRODUCTION: To verify the effectiveness of intervention in early pregnancy for women with early-onset gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS: This study included women with a singleton pregnancy who were diagnosed with early-onset GDM by 20 weeks of gestation according to the International Association of Diabetes and Pregnancy Study Group (IADPSG) threshold. We retrospectively evaluated the pregnancy outcomes in pregnant women with early-onset GDM. In the treatment from early pregnancy group (n=286), patients were diagnosed with early-onset GDM at the Yokohama City University Medical Center (YCU-MC) in 2015-2017 and were treated for GDM from early pregnancy. Concerning the treatment from mid-pregnancy group (n=248), participants were diagnosed with early-onset GDM at five sites, including the YCU-MC in 2018-2019, and were followed up without treatment until the second 75 g oral glucose tolerance test (OGTT) at 24-28 weeks of gestation. Treatment for GDM was given only if the GDM pattern was still present in the second OGTT. RESULTS: There were no significant differences in maternal backgrounds, including GDM risk factors and gestational weight gain, between the groups. Among the treatment from mid-pregnancy group, the false-positive early GDM was 124/248 (50%). Regarding pregnancy outcome, the rate of large for gestational age (LGA) was 8.8% in the treatment from early pregnancy group and 10% in the treatment from mid-pregnancy group, with no significant difference, whereas small for gestational age (SGA) was significantly higher in the treatment from early pregnancy group (9.4%) than in the treatment from mid-pregnancy group (4.8%) (p=0.046). There were no significant differences in maternal adverse events and neonatal outcomes between the groups. In a subanalysis limited to body mass index >25 kg/m2, LGA was significantly lower in the treatment from early pregnancy group than in the treatment from mid-pregnancy group. CONCLUSIONS: The strategy for diagnosing GDM by IADPSG thresholds in early pregnancy and providing treatment to all patients from early pregnancy did not improve the pregnancy outcomes, but rather increased the SGA rate.

In a cervico-isthmic pregnancy, the risk of placenta accreta increases with advancing gestational age. Previous reports have detailed cases that required hysterectomy at delivery or artificial abortion at an early gestational age. However, to the best of our knowledge, there have been no previous reports on the management of a cervico-isthmic pregnancy with fetal death during the second trimester. A 33-year-old primigravid woman was diagnosed with a cervico-isthmic pregnancy and fetal death at 15 weeks of gestation. Placenta accreta was suspected; hence, we chose expectant management and to observe the patient for placental tissue regression. After 5 weeks of expectant management, the ultrasonographic findings suggested remission of placenta accreta. Therefore, we performed a cesarean delivery and terminated the pregnancy. All uterine contents were removed, and the uterus was preserved. In cervico-isthmic pregnancy cases with fetal death, as in the current case, the possibility of fertility preservation could be increased by observing for placental tissue regression through expectant management.
RESUMEN
OBJECTIVES: We aimed to clarify the accuracy of pregnant women's knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children. METHODS: A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women. We then investigated whether participants had knowledge regarding the risk of mother-to child transmission in these diseases and factors associated with their knowledge. RESULTS: We enrolled 2,838 respondents in this study. The rates of agreement for HBV and cervical cancer screening related to human papillomavirus infection were "substantial," those for syphilis was "moderate," and those for HCV and HTLV-1 were "fair," according to the Kappa coefficient. The rate of knowledge regarding mother-to-child transmission of syphilis was highest (37.0%); this rate for the other items was approximately 30%. Increased knowledge was associated with higher educational level and higher annual income. CONCLUSIONS FOR PRACTICE: Pregnant women in Japan had generally good levels of understanding regarding their results in early-pregnancy infectious disease screening. However, they had insufficient knowledge regarding mother-to-child transmission of these diseases. Health care providers should raise awareness in infectious disease prevention among pregnant women and the general public, providing appropriate measures and implementing effective perinatal checkups and follow-ups for infectious diseases.

BACKGROUND: In women with inflammatory bowel disease, at least 3 months of preconception corticosteroid-free remission (CFREM) is recommended by experts in current consensus statements. However, data are lacking on the appropriate preconception remission period. We investigated the appropriate preconception CFREM period in women with ulcerative colitis to reduce maternal disease activity and adverse pregnancy outcomes (ie, preterm birth, low birth weight, and small for gestational age). METHODS: We retrospectively examined 141 pregnancies in women with ulcerative colitis at 2 institutions. We categorized the patients into 3 subgroups by their preconception CFREM period (≥3 months, >0 to <3 months, and non-CFREM). We also investigated disease activity during pregnancy and postpartum and adverse pregnancy outcomes in each group. RESULTS: During pregnancy, the rate of active disease was significantly lower in the ≥3 months and >0 to <3 months CFREM groups compared with that in the non-CFREM group (P < .001 and P = .0257, respectively). Postpartum, the rate of active disease was significantly lower in the ≥3 months CFREM group compared with that in the non-CFREM group (P = .0087). The preconception CFREM period of ≥3 months was an independent inhibitory factor for active disease during pregnancy and postpartum (adjusted odds ratio, 0.15; P = .0035; and adjusted odds ratio, 0.33; P = .027, respectively). Adverse pregnancy outcomes were less common in the >3 months CFREM group compared with those in the other groups, but this difference was not significant. CONCLUSIONS: A preconception CFREM period of more than 3 months may be appropriate for better maternal and adverse pregnancy outcomes, as recommended in consensus statements.
In women with ulcerative colitis, a preconception corticosteroid-free remission period for at least 3 months may be appropriate. This period could reduce disease activity during pregnancy and postpartum and reduce the incidence of adverse pregnancy outcomes.
RESUMEN
AIM: This study aimed to clarify the perinatal prognosis of preeclampsia (PE) with fetal growth restriction (FGR) and determine appropriate medical interventions for these conditions. METHODS: Singleton births delivered to mothers diagnosed with PE with FGR and hypertension at a tertiary center between January 2010 and June 2021 were included. Only patients with PE were included in the analysis, and patients with superimposed PE were excluded. The FGR-preceding group (group F) included patients who developed FGR first and had elevated blood pressure. The remaining cases were defined as the hypertension-preceding group (group H). The perinatal outcomes between the two groups were then compared. The primary outcome was pregnancy prolongation defined as the time from PE diagnosis to delivery. Secondary outcomes included mode of delivery, maternal outcomes, and neonatal outcomes. RESULTS: The mean gestational age at the time of PE diagnosis was 34.7 (26-40.1) weeks for group F and 30.3 (22.6-39.4) weeks for group H (P=0.004). The median pregnancy prolongation from the time of PE diagnosis to delivery was eight (2-30) days in group F and 10.5 (2-43) days in group H, with no significant difference (P=0.52). The incidence of maternal critical complications was 10.4% in group F and 28.1% in group H (P=0.03; odds ratio 3.36; 95% confidence interval 1.13-10). CONCLUSIONS: Among patients with PE, group H was more likely to develop serious maternal complications than group F, suggesting different pathogenesis between these types of PE. Both groups required cautious perinatal management, but more stringent maternal management was required for group H.
RESUMEN
BACKGROUND: Placental abruption (PA) with intrauterine fetal death (IUFD) is associated with a high risk of postpartum hemorrhage (PPH) resulting from severe disseminated intravascular coagulation (DIC). Therefore, blood products that are sufficient for coagulation factor replacement must be prepared, and delivery should occur at referral medical institutions that are equipped with sufficient blood products and emergency transfusion protocols. We retrospectively reviewed the records of patients with PA and IUFD (PA-IUFD) to identify possible factors that may indicate the need for early blood transfusion and investigated whether the Japanese scoring system for PPH can be applied in such cases. METHODS: We used a database of 16,058 pregnant patients who delivered at Yokohama City University Medical Center between January 2000 and February 2016. Thirty-three patients were diagnosed with PA-IUFD before delivery and categorized into two groups-blood transfusion and non-transfusion-to compare the maternal characteristics and pregnancy outcomes. RESULTS: In patients with PA-IUFD, the transfusion group exhibited significantly more blood loss; lower fibrinogen levels and platelet counts; higher levels of fibrin degradation products (FDP), D-dimer, and prothrombin time; and a tendency for tachycardia on admission, compared to the non-transfusion group. Many patients in the transfusion group had normal fibrinogen levels on admission but later displayed markedly decreased fibrinogen levels. The Japan Society of Obstetrics and Gynecology (JSOG) DIC score was significantly higher in the transfusion than in the non-transfusion group. CONCLUSIONS: In PA-IUFD, the fibrinogen level, platelet count, D-dimer, FDP, heart rate, and JSOG DIC score on admission may indicate the need for blood transfusion. However, even with normal fibrinogen levels on admission, continuous monitoring is indispensable for identifying progressive fibrinogen reductions in patients with PA-IUFD.
