“…Second, the mode of delivery was also unknown for all observations, so we cannot assess the impact of caesarian section, which may confound the effect of gestational age on perinatal mortality. The proportion of caesarian deliveries has increased from 17.7% in 2007 to 18.6% in 2011 62 . However, no significant relationship has been found between caesarian section and PMR in Japan 62 , so this limitation may not have a significant effect on the risk factor model presented here.…”

However, no significant relationship has been found between caesarian section and PMR in Japan 62 , so this limitation may not have a significant effect on the risk factor model presented here. We could not fully account for the effect of different coding systems and measurement style between each health facility, or directly adjust for local policies, although these unobserved effects were likely partially adjusted for through the use of a prefecture-level random effect.…”

As Japan has achieved one of the lowest perinatal mortality rates (PMR), our study aims to estimate trends in and risk factors for perinatal mortality among singleton births in Japan. We used Japanese vital registration data to assess trends in and risk factors for perinatal outcomes between 1979 and 2010. Birth and death registration data were merged. An autoregressive integrated moving average model was fitted separately by sex to the PMR and the proportion of stillbirths. A multilevel Poisson regression model was used to estimate risk factors for perinatal mortality. Between 1979 and 2010 there were 40,833,957 pregnancies and 355,193 perinatal deaths, the PMR decreased from 18.86 per 1,000 all births to 3.25 per 1,000 all births, and the proportion of stillbirths increased from 83.6% to 92.1%. Key risk factors for perinatal mortality were low or high birth weight, prematurity and post maturity, and being from poorer or unemployed families. A higher proportion of excess perinatal deaths could be averted by effective policies to prevent stillbirths and improved research into their interventions and risk factors. As the cost and challenge of maintaining perinatal mortality gains increases, policies need to be targeted towards higher risk groups and social determinants of health.

“…PA is a potentially catastrophic condition with high maternal-fetal morbidity, which is increasing in prevalence worldwide [6,7,11,12]. Despite its importance and widely documented sequelae, there is yet a consensus in the optimal management strategies for care of pregnancies with this condition.…”

“…However, it is apparent that the single most important risk factor of PA is prior caesarean section (CS) [3][4][5]. Of important note, the increasing rate of CS deliveries worldwide, particularly in developed countries, has unquestionably led to a concurrent rise in the incidence of PA [6,7]. The last half a century has seen a steady increase in the rate of PA; from a reported occurrence of one in 4,027 in 1970s [8], increasing to one in 2,510 in the 1980s [5], up to as high as one in 533 in 1990s and 2000s [9].…”

Purpose of investigation:To report a ten-year experience in management of a highly morbid obstetrical condition in placenta accreta (PA) at a tertiary referral centre, uniquely equipped with an integrated Interventional Radiology theatre, with a primary aim to guide best practice. Materials and Methods: Retrospective analysis of all histologically proven PA cases at a tertiary centre in Australia between January 2004 and December 2013. Medical records were reviewed for obstetrics history, operative details, post-operative management and neonatal outcome. Results: Sixteen cases of PA were identified during the time period; 75% had identifiable risk factors for PA and 87.5% of patients were diagnosed antenatally. Mean gestational age at time of delivery was 34 ± 3.4 weeks. Ten cases were performed electively, while the remaining underwent emergency caesarean section. One patient was managed conservatively with placenta left insitu; time to complete resolution of placenta was 71 days. Among patients who underwent hysterectomy (15/16), the proportion of total (n=8) vs. subtotal (n=7) hysterectomy was similar. Average operating time was 123 ± 45.9 minutes. Compared to emergency cases, patients who underwent elective surgery had significantly lower blood loss (2.2 vs. 3.1 L, p < 0.05). Common iliac artery balloons were deployed in eight cases, with a non-statistically significant reduction in intraoperative blood loss (2 vs. 3.2 L, p < 0.05). Fifty percent of patients required ICU admission. Neonatal survival at six months was 93.75% (15/16). Conclusion: The present report demonstrates the importance of timely diagnosis and comprehensive preparation in the surgical management of patients with placenta accreta. The availability of relevant services in the peri-operative phase, including: obstetricians, interventional radiology facility and personnel, intensive care, and neonatology teams, are crucial in achieving optimal outcome for the patient and neonate. In line with reports in the literature, the authors advocate a team-based multidisciplinary approach in a tertiary-level centre for management of this high-risk condition.

“…In Japan, however, the lack of obstetricians caused by a poor work environment and increasing medical lawsuits have prevented the implementation of a strict 24-hour delivery monitoring system at many obstetric facilities [910]. For example, although our institute is one of the 29 major perinatal centers in Tokyo, Japan (about 1,900–2,100 deliveries per year), only 1–2 obstetricians are routinely on staff overnight (5:20 PM to 8:20 AM).…”

ObjectiveThe lack of obstetricians in Japan has prevented the implementation of a 24–hour delivery monitoring system for high-risk deliveries such as twin vaginal delivery at many obstetric facilities. To examine the outcomes of a 1-day trial of the vaginal delivery of twins at 36–37 weeks' gestation.MethodsWe induced the vaginal delivery of twins at 36–37 weeks' gestation of 256 women who provided consent between January 2007 and December 2016 using the following protocol: 1) administration of 0.5 mg oral prostaglandin E2 every 1 hour (maximum: 1.5 mg) in the morning; 2) intravenous administration of oxytocin and amniotomy in the afternoon; and 3) selection of caesarean delivery when vaginal delivery was not expected by evening. We examined their perinatal outcomes in a chart review.ResultsThe completion rates of vaginal delivery in total, nulliparous, and multiparous women were 79%, 72%, and 84%, respectively. There were no cases of neonatal asphyxia. The total incidence of neonatal respiratory disorders was 2.1%, but there were no cases of persistent pulmonary hypertension. The total incidence of postpartum hemorrhage requiring transfusion was 2.7%.ConclusionThe 1-day planned vaginal delivery of twins at 36–37 weeks' gestation appears valid and safe, and our findings suggest that it can be an option for the delivery of twins.
