Background: A history of stillbirth is a risk factor for recurrent fetal death in a subsequent pregnancy. Reported risks of recurrent fetal death are often not stratified by gestational age. In subsequent pregnancies increased rates of medical interventions are reported without evidence of perinatal benefit. The aim of this study was to estimate gestational-age specific risks of recurrent stillbirth and to evaluate the effect of obstetrical management on perinatal outcome after previous stillbirth., Methods: A retrospective cohort study in the Netherlands was designed that included 252.827 women with two consecutive singleton pregnancies (1 st and 2 nd delivery) between 1999 and 2007. Data was obtained from the national Perinatal Registry and analyzed for pregnancy outcomes. Fetal deaths associated with a congenital anomaly were excluded. The primary outcome was the occurrence of stillbirth in the second pregnancy stratified by gestational age. Secondary outcome was the influence of obstetrical management on perinatal outcome in a subsequent pregnancy., Results: Of 252.827 first pregnancies, 2.058 pregnancies ended in a stillbirth (8.1 per 1000). After adjusting for confounding factors, women with a prior stillbirth have a two-fold higher risk of recurrence (aOR 1.96, 95% CI 1.07-3.60) compared to women with a live birth in their first pregnancy. The highest risk of recurrence occurred in the group of women with a stillbirth in early gestation between 22 and 28 weeks of gestation (a OR 2.25, 95% CI 0.62-8.15), while after 32 weeks the risk decreased. The risk of neonatal death after 34 weeks of gestation is higher in women with a history of stillbirth (aOR 6.48, 95% CI 2.61-16.1) and the risk of neonatal death increases with expectant obstetric management (aOR 10.0, 95% CI 2.43-41.1)., Conclusions: A history of stillbirth remains an important risk for recurrent stillbirth especially in early gestation (22-28 weeks). Women with a previous stillbirth should be counselled for elective induction in the subsequent pregnancy at 37-38 weeks of gestation to decrease the risk of perinatal death., (© 2021.

Background: Stillbirth, the death of a baby before birth, is associated with significant psychological and social consequences that can be mitigated by respectful and supportive bereavement care. The absence of high-level evidence to support the broad scope of perinatal bereavement practices means that offering a range of options identified as valued by parents has become an important indicator of care quality. This study aimed to describe bereavement care practices offered to parents across different high-income and middle-income countries., Methods: An online survey of parents of stillborn babies was conducted between December 2014 and February 2015. Frequencies of nine practices were compared between high-income and middle-income countries. Differences in proportions of reported practices and their associated odds ratios were calculated to compare high-income and middle-income countries., Results: Over three thousand parents (3041) with a self-reported stillbirth in the preceding five years from 40 countries responded. Fifteen countries had atleast 40 responses. Significant differences in the prevalence of offering nine bereavement care practices were reported by women in high-income countries (HICs) compared with women in middle-income countries (MICs). All nine practices were reported to occur significantly more frequently by women in HICs, including opportunity to see and hold their baby (OR = 4.8, 95% CI 4.0-5.9). The widespread occurrence of all nine practices was reported only for The Netherlands., Conclusions: Bereavement care after stillbirth varies between countries. Future research should look at why these differences occur, their impact on parents, and whether differences should be addressed, particularly how to support effective communication, decision-making, and follow-up care., (© 2021 Wiley Periodicals LLC.)

Immune cells are critically involved in placental development and functioning, and inadequate regulation of the maternal immune system is associated with placental pathology and pregnancy complications. This study aimed to explore numbers of decidual immune cells in pregnancies complicated with fetal growth restriction (FGR) and stillbirth (SB), and in placentas with histopathological lesions: maternal vascular malperfusion (MVM), fetal vascular malperfusion (FVM), delayed villous maturation (DVM), chorioamnionitis (CA), and villitis of unknown etiology (VUE). Placental tissue from FGR ( n = 250), SB ( n = 64), and healthy pregnancies ( n = 42) was included. Histopathological lesions were classified according to criteria developed by the Amsterdam Placental Workshop Group. Tissue slides were stained for CD68 (macrophages), CD206 (M2-like macrophages), CD3 (T cells), FOXP3 [regulatory T (Treg) cells], and CD56 [natural killer (NK) cells]. Cell numbers were analyzed in the decidua basalis using computerized morphometry. The Mann-Whitney U -test and Kruskal Wallis test with the Dunn's as post-hoc test were used for statistical analysis. Numbers of CD68 + macrophages were higher in FGR compared to healthy pregnancies ( p < 0.001), accompanied by lower CD206 + /CD68 + ratios ( p < 0.01). In addition, in FGR higher numbers of FOXP3 + Treg cells were seen ( p < 0.01) with elevated FOXP3 + /CD3 + ratios ( p < 0.01). Similarly, in SB elevated FOXP3 + Treg cells were found ( p < 0.05) with a higher FOXP3+/CD3+ ratio ( p < 0.01). Furthermore, a trend toward higher numbers of CD68 + macrophages was found ( p < 0.1) in SB. Numbers of CD3 + and FOXP3 + cells were higher in placentas with VUE compared to placentas without lesions ( p < 0.01 and p < 0.001), accompanied by higher FOXP3 + /CD3 + ratios ( p < 0.01). Elevated numbers of macrophages with a lower M2/total macrophage ratio in FGR suggest a role for a macrophage surplus in its pathogenesis and could specifically indicate involvement of inflammatory macrophages. Higher numbers of FOXP3 + Treg cells with higher Treg/total T cell ratios in VUE may be associated with impaired maternal-fetal tolerance and a compensatory response of Treg cells. The abundant presence of placental lesions in the FGR and SB cohorts might explain the increase of Treg/total T cell ratios in these groups. More functionality studies of the observed altered immune cell subsets are needed., (Copyright © 2020 Bezemer, Schoots, Timmer, Scherjon, Erwich, van Goor, Gordijn and Prins.)

Objective: To assess the frequency of additional care, and parents' perceptions of quality, respectful care, in pregnancies subsequent to stillbirth., Design: Multi-language web-based survey., Setting: International., Population: A total of 2716 parents, from 40 high- and middle-income countries., Methods: Data were obtained from a broader survey of parents' experiences following stillbirth. Data were analysed using descriptive statistics and stratified by geographic region. Subgroup analyses explored variation in additional care by gestational age at index stillbirth., Main Outcome Measures: Frequency of additional care, and perceptions of quality, respectful care., Results: The majority (66%) of parents conceived their subsequent pregnancy within 1 year of stillbirth. Additional antenatal care visits and ultrasound scans were provided for 67% and 70% of all parents, respectively, although there was wide variation across geographic regions. Care addressing psychosocial needs was less frequently provided, such as additional visits to a bereavement counsellor (10%) and access to named care provider's phone number (27%). Compared with parents whose stillbirth occurred at ≤ 29 weeks of gestation, parents whose stillbirth occurred at ≥ 30 weeks of gestation were more likely to receive various forms of additional care, particularly the option for early delivery after 37 weeks. Around half (47-63%) of all parents felt that elements of quality, respectful care were consistently applied, such as spending enough time with parents and involving parents in decision-making., Conclusions: Greater attention is required to providing thoughtful, empathic and collaborative care in all pregnancies following stillbirth. Specific education and training for health professionals is needed., Tweetable Abstract: More support for providing quality care in pregnancies after stillbirth is needed., Plain Language Summary: Study rationale and design More than two million babies are stillborn every year. Most parents will conceive again soon after having a stillborn baby. These parents are more likely to have another stillborn baby in the next pregnancy than parents who have not had a stillborn baby before. The next pregnancy after stillbirth is often an extremely anxious time for parents, as they worry about whether their baby will survive. In this study we asked 2716 parents from 40 countries about the care they received during their first pregnancy after stillbirth. Parents were recruited mainly through the International Stillbirth Alliance and completed on online survey that was available in six languages. Findings Parents often had extra antenatal visits and extra ultrasound scans in the next pregnancy, but they rarely had extra emotional support. Also, many parents felt their care providers did not always listen to them and spend enough time with them, involve them in decisions, and take their concerns seriously. Parents were more likely to receive various forms of extra care in the next pregnancy if their baby had died later in pregnancy compared to earlier in pregnancy. Limitations In this study we only have information from parents who were able and willing to complete an online survey. Most of the parents were involved in charity and support groups and most parents lived in developed countries. We do not know how well the findings relate to other parents. Finally, our study does not include parents who may have tried for another pregnancy but were not able to conceive. Potential impact This study can help to improve care through the development of best practice guidelines for pregnancies following stillbirth. The results suggest that parents need better emotional support in these pregnancies, and more opportunities to participate actively in decisions about care. Extra support should be available no matter how far along in pregnancy the previous stillborn baby died., (© 2016 Royal College of Obstetricians and Gynaecologists.)

Objective: To provide prognostic information to help parents to reach an informed decision about termination or continuation of the pregnancy and to shape peripartum policy based on a large European cohort., Method: Thirteen registries from the European Surveillance of Congenital Anomalies (EUROCAT) network contributed data from January 1, 1998, to December 31, 2011. Terminations for fetal anomalies were excluded. Chromosomal anomalies, syndromes and isolated anomaly groups were distinguished according to EUROCAT guidelines. Perinatal mortality, stillbirths, and early and late neonatal mortality rates (NMRs) were analyzed by anomaly group and gestational age., Results: Among 73 337 cases, perinatal mortality associated with congenital anomaly was 1.27 per 1000 births (95% confidence interval, 1.23-1.31). Average stillbirth rate was 2.68% (range 0%-51.2%). Early and late NMR were 2.75% (range 0%-46.7%) and 0.97% (range 0%-17.9%), respectively. Chromosomal anomalies and syndromes, and most isolated anomalies, had significant differences regarding timing of fetal demise compared to the general population. Chromosomal and central nervous system anomalies had higher term stillbirth rates., Conclusions: We found relevant differences between anomalies regarding rates of stillbirth, NMR, and timing by gestational age. Our data can help parents to decide about their unborn child with a congenital anomaly and help inform maternal-fetal medicine specialists regarding peripartum management., (© 2017 John Wiley & Sons, Ltd.)

Accurate and consistent classification of causes and associated conditions for perinatal deaths is essential to inform strategies to reduce the five million which occur globally each year. With the majority of deaths occurring in low- and middle-income countries (LMICs), their needs must be prioritised. The aim of this paper is to review the classification of perinatal death, the contemporary classification systems including the World Health Organization's International Classification of Diseases - Perinatal Mortality (ICD-PM), and next steps. During the period from 2009 to 2014, a total of 81 new or modified classification systems were identified with the majority developed in high-income countries (HICs). Structure, definitions and rules and therefore data on causes vary widely and implementation is suboptimal. Whereas system testing is limited, none appears ideal. Several systems result in a high proportion of unexplained stillbirths, prompting HICs to use more detailed systems that require data unavailable in low-income countries. Some systems appear to perform well across these different settings. ICD-PM addresses some shortcomings of ICD-10 for perinatal deaths, but important limitations remain, especially for stillbirths. A global approach to classification is needed and seems feasible. The new ICD-PM system is an important step forward and improvements will be enhanced by wide-scale use and evaluation. Implementation requires national-level support and dedicated resources. Future research should focus on implementation strategies and evaluation methods, defining placental pathologies, and ways to engage parents in the process., (Copyright © 2017 Elsevier Ltd.

Stillbirth is a major obstetric complication, with 3.2 million stillbirths worldwide and 26,000 stillbirths in the United States every year. The Eunice Kennedy Shriver National Institute of Child Health and Human Development held a workshop from October 22-24, 2007, to review the pathophysiology of conditions underlying stillbirth to define causes of death. The optimal classification system would identify the pathophysiologic entity initiating the chain of events that irreversibly led to death. Because the integrity of the classification is based on available pathologic, clinical, and diagnostic data, experts emphasized that a complete stillbirth workup should be performed. Experts developed evidence-based characteristics of maternal, fetal, and placental conditions to attribute a condition as a cause of stillbirth. These conditions include infection, maternal medical conditions, antiphospholipid syndrome, heritable thrombophilias, red cell alloimmunization, platelet alloimmunization, congenital malformations, chromosomal abnormalities including confined placental mosaicism, fetomaternal hemorrhage, placental and umbilical cord abnormalities including vasa previa and placental abruption, complications of multifetal gestation, and uterine complications. In all cases, owing to lack of sufficient knowledge about disease states and normal development, there will be a degree of uncertainty regarding whether a specific condition was indeed the cause of death.

The article discusses the ICD-PM perinatal period deaths classification being developed by the World Health Organization based on existing International Classification of Diseases-10 (ICD-10) codes. Topics include reference to unrecognized stillbirths or neonatal deaths, unifying perinatal death classification system with the contributing maternal factors as well as convened groups of experts such as obstetricians and neonatologists. Also mentioned are ICD-MM codes and the epidemiologists.

Objective: To apply the World Health Organization (WHO) Application of the International Classification of Diseases, tenth revision (ICD-10) to deaths during the perinatal period: ICD-Perinatal Mortality (ICD-PM) to existing perinatal death databases.Design: Retrospective application of ICD-PM.Setting: South Africa, UK.Population: Perinatal death databases.Methods: Deaths were grouped according to timing of death and then by the ICD-PM cause of death. The main maternal condition at the time of perinatal death was assigned to each case.Main Outcome Measures: Causes of perinatal mortality, associated maternal conditions.Results: In South Africa 344/689 (50%) deaths occurred antepartum, 11% (n = 74) intrapartum and 39% (n = 271) in the early neonatal period. In the UK 4377/9067 (48.3%) deaths occurred antepartum, with 457 (5%) intrapartum and 4233 (46.7%) in the neonatal period. Antepartum deaths were due to unspecified causes (59%), chromosomal abnormalities (21%) or problems related to fetal growth (14%). Intrapartum deaths followed acute intrapartum events (69%); neonatal deaths followed consequences of low birthweight/ prematurity (31%), chromosomal abnormalities (26%), or unspecified causes in healthy mothers (25%). Mothers were often healthy; 53%, 38% and 45% in the antepartum, intrapartum and neonatal death groups, respectively. Where there was a maternal condition, it was most often maternal medical conditions, and complications of placenta, cord and membranes.Conclusions: The ICD-PM can be a globally applicable perinatal death classification system that emphasises the need for a focus on the mother-baby dyad as we move beyond 2015.Tweetable Abstract: ICD-PM is a global system that classifies perinatal deaths and links them to maternal conditions.

Objective: The WHO application of the tenth edition of the International Classification of Diseases (ICD-10) to deaths during the perinatal period (ICD Perinatal Mortality, ICD-PM) captures the essential characteristics of the mother-baby dyad that contribute to perinatal deaths. We compare the capture of maternal conditions in the existing ICD-PM with the maternal codes from the WHO application of ICD-10 to deaths during pregnancy, childbirth, and the puerperium (ICD Maternal Mortality, ICD-MM) to explore potential benefits in the quality of data received.Design: Retrospective application of ICD-PM.Setting: South Africa and the UK.Population: Perinatal death databases.Methods: The maternal conditions were classified using the ICD-PM groupings for maternal condition in perinatal death, and then mapped to the ICD-MM groupings of maternal conditions.Main Outcome Measures: Main maternal conditions in perinatal deaths.Results: We reviewed 9661 perinatal deaths. The largest group (4766 cases, 49.3%) in both classifications captures deaths where there was no contributing maternal condition. Each of the other ICD-PM groups map to between three and six ICD-MM groups. If the cases in each ICD-PM group are re-coded using ICD-MM, each group becomes multiple, more specific groups. For example, the 712 cases in group M4 in ICD-PM become 14 different and more specific main disease categories when the ICD-MM is applied instead.Conclusions: As we move towards ICD-11, the use of the more specific, applicable, and relevant codes outlined in ICD-MM for both maternal deaths and the maternal condition at the time of a perinatal death would be preferable, and would provide important additional information about perinatal deaths.Tweetable Abstract: Improving the capture of maternal conditions in perinatal deaths provides important actionable information.

In this BJOG stillbirth themed issue, Campbell et al BJOG 2018 XX.XXX report on a population-based cost of illness study. Although reports on costs in healthcare are not unusual, and even quality of life studies are incorporating translations of quality of life into money-estimates, one can feel uneasy when talking about money regarding stillbirth. It seems insensitive towards the people suffering from their loss. How can one put a monetary value on a life not yet lived? However, these authors should be congratulated for building upon earlier work in their effort to tackle this difficult and long neglected topic (Heazell et al Lancet 2016;387:604-616).
