Abstract Clinical guidelines for obstetrical practice were first published by the Japan Society of Obstetrics and Gynecology (JSOG) Association Obstetricians Gynecologists (JAOG) in 2008, a revised version was 2011. The aims this publication include determination current standard care practices pregnant women Japan, widespread use practices, enhancement safety practice, reduction burdens associated with medico‐legal medico‐economical problems, better understanding between maternity‐service...
The proportions of preterm birth (PTB, ie., delivered before 37 gestational weeks) and low weight (LBW, less than 2500 g at delivery) have been rising in developed countries. We sought to examine the factors contributing rise Japan, with particular focus on effects obstetric interventions. used a database maintained by one large regional hospital Shizuoka, Japan. restricted analysis mothers who live singleton births from 1997 2010 (n = 19,221). assessed temporal trends PTB LBW, then divided...
To clarify the problems related to maternal deaths in Japan, including diseases themselves, causes, treatments and hospital or regional systems.Descriptive study.Maternal death registration system established by Japan Association of Obstetricians Gynecologists (JAOG).Women who died during pregnancy within a year after delivery, from 2010 2014, throughout (N=213).The preventability each death.Maternal were frequently caused obstetric haemorrhage (23%), brain disease (16%), amniotic fluid...
<i>Objectives:</i> To evaluate the prognosis of monochorionic twins with selective intrauterine growth restriction (sIUGR), classified according to type umbilical artery Doppler, under expectant management. <i>Methods:</i> The outcome 81 cases isolated sIUGR was evaluated a classification based on (UA) Doppler diastolic flow in IUGR twin (I: present, II: constantly absent/reverse, III: intermittently absent/reverse). Selective feticide not considered due legal...
Abstract Objectives To evaluate the outcome and preoperative risks of twin–twin transfusion syndrome (TTTS) following fetoscopic laser surgery (FLS). Methods A retrospective cohort study a series 181 consecutive cases TTTS before 26 weeks' gestation subjected to FLS at four centers in Japan between July 2002 December 2006. Results The chances survival least one twin 28 days age 6 months were 91.2% 90.1%, respectively. rate major neurological complications survivors was 4.7%. Preoperative...
The aim of this study was to evaluate the use ultrasound assessment predict risk mortality in expectantly managed monochorionic twin fetuses with selective intrauterine growth restriction (sIUGR).This a retrospective 101 pregnancies diagnosed sIUGR before 26 weeks gestation. All patients were under expectant management during observation period. At initial evaluation, presence or absence each following abnormalities documented: oligohydramnios; stuck phenomenon; severe IUGR < 3(rd) centile...
The adverse effects of maternal and paternal smoking on child health have been studied. However, few studies demonstrate the interaction maternal/paternal smoking, birth outcomes other than weight not evaluated. present study examined individual their interactions outcomes. A follow-up hospital-based from pregnancy to delivery was conducted 1997 2010 with parents newborn infants who delivered at a large hospital in Hamamatsu, Japan. relationships between growth were evaluated logistic...
Abstract This descriptive study was based on the maternal death registration system established by Japan Association of Obstetricians and Gynecologists Maternal Death Exploratory Committee (JMDEC). 361 women died during pregnancy or within 42 days after delivery between January 2010 June 2017 throughout were analysed, in order to investigate trend deaths related obstetric medical practice. Reports consistent, ranging from 45 cases 44 2017. Among all deaths, frequency due haemorrhage ranged...
Preterm births cause a large public-health burden, and air pollution is considered to be potential risk factor. We evaluated the association between proximity major roads (as an index for pollution) preterm births, classified by gestational age specific clinical manifestations.Data on parental information birth outcomes were extracted from database maintained perinatal hospital in Shizuoka, Japan. restricted analysis mothers who delivered liveborn single 1997 2008 (n = 14,226). Using...
Hypoxic-ischemic encephalopathy (HIE) is one of the most critical pathologic conditions in neonatal medicine due to potential for neurological deficits later life. We investigated incidence term infants with moderate or severe HIE Japan and identified prognostic risk factors poor outcome HIE.Data on 227 diagnosed born between January December 2008 were collected via nationwide surveys from 263 responding hospitals. Using logistic regression, we examined relationship maternal, antepartum,...
Abstract Aim: The aim of this study was to evaluate the perinatal outcome monochorionic diamniotic (MD) twin gestations managed from early gestation onward at a single center. Material and Methods: This retrospective single‐cohort study, spanning 6 years, 219 MD pregnancies who received prenatal care before 14 weeks delivered our subjects were all under same management protocol. incidence fetal or neonatal death, major neurological complications 28 days age, twin–twin transfusion syndrome...
Exposure to air pollution has been demonstrated increase the risk of preterm birth and low weight (LBW). Although evidence accumulated on characteristics associated with increased pollution-related health effects, most studies have conducted in adult population reproductive outcomes is limited. We examined whether socio-economic position (SEP) parental (parental behavior co-morbidity) modified relationship between adverse outcomes. Data were extracted from a perinatal hospital database based...
Background:The aim of this study was to clarify the clinical features maternal death due stroke associated with pregnancy-induced hypertension (PIH) in Japan.Methods and Results:Reported deaths occurring between 2010 2012 throughout Japan were analyzed by Maternal Death Exploratory Committee. Among a total 154 reports death, those (n=12) or without (n=13) PIH compared. Cerebral occurred more frequently third trimester during second stage labor PIH, whereas it at any time point not involving...
Abstract Aim This study aimed to clarify the feasibility and perinatal outcomes of fetoscopic laser photocoagulation (FLP) for monochorionic twin gestation with selective intrauterine growth restriction (sIUGR) accompanied by both abnormal umbilical artery Doppler waveforms isolated severe oligohydramnios sIUGR twin. Methods In this prospective clinical trial, which included 10 cases absent or reversed end‐diastolic flow in twin, main investigated were FLP rate FLP‐related maternal...
This study aimed to clarify the relationship between maternal mortality and advanced age in Japan provide useful information for future perinatal management. Maternal death rates by group were investigated all deaths an 11-year period, from 2010 2021. among those aged ≥ 40 years examined detail determine cause, number of cause was calculated. The causes onset most common also investigated. 0.8 (95% confidence interval [CI] 0.3-4.7) < 20 years, 2.6 CI 1.7-3.8) 20-24 2.9 2.3-3.6) 25-29 3.9...
