Stillbirths: economic and psychosocial consequences

Stillbirth diagnosis and classification: comparison of ReCoDe and ICD-PM systems

OBJECTIVES

The identification of causes of stillbirth (SB) can be a challenge due to several different classification systems of SB causes. In the scientific literature there is a continuous emergence of SB classification systems, not allowing uniform data collection and comparisons between populations from different geographical areas. For these reasons, this study compared two of the most used SB classifications, aiming to identify which of them should be preferable.

METHODS

A total of 191 SBs were retrospectively classified by a panel composed by three experienced-physicians throughout the ReCoDe and ICD-PM systems to evaluate which classification minimizes unclassified/unspecified cases. In addition, intra and inter-rater agreements were calculated.

RESULTS

ReCoDe defined: the 23.6% of cases as unexplained, placental insufficiency in the 14.1%, lethal congenital anomalies in the 12%, infection in the 9.4%, abruptio in the 7.3%, and chorioamnionitis in the 7.3%. ICD-PM defined: the 20.9% of cases as unspecified, antepartum hypoxia in the 44%, congenital malformations, deformations, and chromosomal abnormalities in the 11.5%, and infection in the 11.5%. For ReCoDe, inter-rater was agreement of 0.58; intra-rater agreements were 0.78 and 0.79. For ICD-PM, inter-rater agreement was 0.54; intra-rater agreements were of 0.76 and 0.71.

CONCLUSIONS

There is no significant difference between ReCoDe and ICD-PM classifications in minimizing unexplained/unspecified cases. Inter and intra-rater agreements were largely suboptimal for both ReCoDe and ICD-PM due to their lack of specific guidelines which can facilitate the interpretation. Thus, the authors suggest correctives strategies: the implementation of specific guidelines and illustrative case reports to easily solve interpretation issues.

Perinatal mortality audits and reporting of perinatal deaths: systematic review of outcomes and barriers

BACKGROUND

Perinatal deaths are a devastating experience for all families and healthcare professionals involved. Audit of perinatal mortality (PNM) is essential to better understand the factors associated with perinatal death, to identify key deficiencies in healthcare provision and should be utilised to improve the quality of perinatal care. However, barriers exist to successful audit implementation and few countries have implemented national perinatal audit programs.

CONTENT

We searched the PubMed, EMBASE and EBSCO host, including Medline, Academic Search Complete and CINAHL Plus databases for articles that were published from 1st January 2000. Articles evaluating perinatal mortality audits or audit implementation, identifying risk or care factors of perinatal mortality through audits, in middle and/or high-income countries were considered for inclusion in this review. Twenty articles met inclusion criteria. Incomplete datasets, nonstandard audit methods and classifications, and inadequate staff training were highlighted as barriers to PNM reporting and audit implementation. Failure in timely detection and management of antenatal maternal and fetal conditions and late presentation or failure to escalate care were the most common substandard care factors identified through audit. Overall, recommendations for perinatal audit focused on standardised audit tools and training of staff. Overall, the implementation of audit recommendations remains unclear.

SUMMARY

This review highlights barriers to audit practices and emphasises the need for adequately trained staff to participate in regular audit that is standardised and thorough. To achieve the goal of reducing PNM, it is crucial that the audit cycle is completed with continuous re-evaluation of recommended changes.

The prevalence of and risk factors for stillbirths in women with severe preeclampsia in a high-burden setting at Mpilo Central Hospital, Bulawayo, Zimbabwe

OBJECTIVES

Stillbirth remains a global public health issue; in low-resource settings stillbirth rates remain high (>12 per 1,000 births target of Every Newborn Action Plan). Preeclampsia is major risk factor for stillbirths. This study aimed to determine the prevalence and risk factors for stillbirth amongst women with severe preeclampsia at Mpilo Central Hospital.

METHODS

A retrospective cross-sectional study was conducted of women with severe preeclampsia from 01/01/2016 to 31/12/2018 at Mpilo Central Hospital, Bulawayo, Zimbabwe. Multivariable logistic regression was used to determine risk factors that were independently associated with stillbirths.

RESULTS

Of 469 women that met the inclusion criteria, 46 had a stillbirth giving a stillbirth prevalence of 9.8%. The risk factors for stillbirths in women with severe preeclampsia were: unbooked status (adjusted odds ratio (aOR) 3.01, 95% (confidence interval) CI 2.20-9.10), frontal headaches (aOR 2.33, 95% CI 0.14-5.78), vaginal bleeding with abdominal pain (aOR 4.71, 95% CI 1.12-19.94), diastolic blood pressure ≥150 mmHg (aOR 15.04, 95% CI 1.78-126.79), platelet count 0-49 × 10⁹/L (aOR 2.80, 95% CI 1.26-6.21), platelet count 50-99 × 10⁹/L (aOR 2.48, 95% CI 0.99-6.18), antepartum haemorrhage (aOR 12.71, 95% CI 4.15-38.96), haemolysis elevated liver enzymes syndrome (HELLP) (aOR 6.02, 95% CI 2.22-16.33) and fetal sex (aOR 2.75, 95% CI 1.37-5.53).

CONCLUSIONS

Women with severe preeclampsia are at significantly increased risk of stillbirth. This study has identified risk factors for stillbirth in this high-risk population; which we hope could be used by clinicians to reduce the burden of stillbirths in women with severe preeclampsia.

Viral infections in stillbirth: a contribution underestimated in Mexico?

OBJECTIVES

To analyze the role of viral infections as etiology of stillbirths in Mexico and their epidemiological impact in the context of the global Every Newborn Initiative.

METHODS

A comprehensive literature search was performed in electronic databases related to stillbirth and viral infections published prior to January 19th 2021. Stillbirths records and causes from National Mexican databases, during 2008-2019 period were also computed.

RESULTS

Only two articles with a direct relationship between viral infection and stillbirth were found, and one article with an indirect serological association was identified. During the analyzed period there were 198,076 stillbirths, with a National stillbirth rate (SBR) ranging from 6.9 to 6.5 between 2008 and 2014, with a subsequent increase to reach 7.7 in 2019. Only 19 cases were attributed to viral causes and a specific virus was identified in 11. The main causes of early stillbirth were a fetus with premature rupture of membranes and light for gestational age, and for late stillbirth these were fetus affected by oligohydramnios and slow fetal growth. The percentage classified as unspecified deaths varied from 34.4-41.9%.

CONCLUSIONS

In Mexico, there has been an increase in SBR during last years, but the goals of the Every Newborn Initiative is met. More than 14,500 stillbirths with at least 5,100 unspecified cases have been reported per year, and only 11 cases were attributable to a specific virus, highlighting the serious underestimation of cases and the need of implementation of routine viral diagnosis methods to improve the care of this global health problem.

Investigation and management of stillbirth: a descriptive review of major guidelines

Stillbirth is a common and devastating pregnancy complication. The aim of this study was to review and compare the recommendations of the most recently published guidelines on the investigation and management of this adverse outcome. A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Royal College of Obstetricians and Gynecologists (RCOG), the Perinatal Society of Australia and New Zealand (PSANZ), the Society of Obstetricians and Gynecologists of Canada (SOGC) on stillbirth was carried out. Regarding investigation, there is consensus that medical history and postmortem examination are crucial and that determining the etiology may improve care in a subsequent pregnancy. All guidelines recommend histopathological examination of the placenta, genetic analysis and microbiology of fetal and placental tissues, offering less invasive techniques when autopsy is declined and a Kleihauer test to detect large feto-maternal hemorrhage, whereas they discourage routine screening for inherited thrombophilias. RCOG and SOGC also recommend a complete blood count, coagulopathies' testing, anti-Ro and anti-La antibodies' measurement in cases of hydrops and parental karyotyping. Discrepancies exist among the reviewed guidelines on the definition of stillbirth and the usefulness of thyroid function tests and maternal viral screening. Moreover, only ACOG and RCOG discuss the management of stillbirth. They agree that, in the absence of coagulopathies, expectant management should be considered and encourage vaginal birth, but they suggest different labor induction protocols and different management in subsequent pregnancies. It is important to develop consistent international practice protocols, in order to allow effective determination of the underlying causes and optimal management of stillbirths, while identifying the gaps in the current literature may highlight the need for future research.

Stillbirth aftercare in a tertiary obstetric center - parents' experiences

OBJECTIVES

This study aimed to assess parents' satisfaction with received care and support when experiencing stillbirth.

METHODS

This was a questionnaire survey conducted at Helsinki University Hospital, Helsinki, Finland during 2016-2020. Separate questionnaires were sent to mothers and partners who had experienced an antepartum singleton stillbirth at or after 22 gestational weeks during 2016-2019. The questionnaire covered five major topics: stillbirth diagnosis, delivery, information on postmortem examinations, aftercare at the ward, and follow-up appointment.

RESULTS

One hundred nineteen letters were sent and 57 (47.9%) of the mothers and 46 (38.7%) of their partners responded. Both mothers and their partners felt well supported during delivery. They were also satisfied with the time holding their newborn. Partners reported even higher satisfaction in this aspect with a significant within-dyad difference (p=0.049). Parents were generally pleased with the support at the ward. However, both groups were less satisfied with social worker counseling (mothers 53.7%, partners 61.0%). The majority felt that the follow-up visit was helpful. Nonetheless, a remarkable proportion felt that the follow-up visit increased their anxiousness (25.9%, 14.0%, p=0.018). Partners rated their mood higher than mothers (p=0.001). Open feedback revealed that the support received after discharge from hospital was often insufficient.

CONCLUSIONS

Our study showed that the parents who experience stillbirth in our institution receive mostly adequate care and support during their hospital stay. However, there is room for further training of healthcare professionals and other professionals contributing in stillbirth aftercare.

Perinatal bereavement care during COVID-19 in Australian maternity settings

OBJECTIVES

Perinatal bereavement care is a complex area of practice. The COVID-19 pandemic led to reconfiguration of maternity and perinatal bereavement care services. This study explores Australian health care providers' perspectives of the impact of COVID-19 on the provision of respectful and supportive care following stillbirth or neonatal death.

METHODS

Members of a perinatal bereavement care network were consulted at the commencement of the pandemic in Australia using an online feedback form. Respondents provided ratings and free-text comments on the impact of COVID-19 on implementation of 49 recommendations contained in the Perinatal Society of Australia and New Zealand/Stillbirth Centre of Research Clinical Practice Guideline for Respectful and Supportive Perinatal Bereavement Care.

RESULTS

Responses were received from 35 health care providers who provided perinatal bereavement care in clinical settings or through support organisations in Australia. Major impacts of COVID-19 were reported for 8 of 49 guideline recommendations. Impacts included reduced: support for mothers due to visitor restrictions; availability of cultural and spiritual support and interpreters; involvement of support people in decision-making; options for memory-making and commemorative rituals; and staff training and supervision. Adaptations to minimise impacts included virtual consultations, online staff training, use of cold cots, and increased staff support for memory-making.

CONCLUSIONS

Health care providers encounter substantial challenges as they strive to implement best practice perinatal bereavement care in pandemic conditions. Some practice adaptations developed during the COVID-19 pandemic could benefit parents; however, evaluation of their effectiveness and acceptability is needed.

Identifying the High-Risk Fetus in the Low-Risk Mother Using Fetal Doppler Screening

Continuous-wave Doppler ultrasound of the umbilical artery offers an inexpensive and scalable method of detecting undiagnosed fetal growth restriction. Using Doppler to screen low-risk pregnancies in low- and middle-income countries identifies fetuses at risk of stillbirth and, when managed appropriately, results in a step change reduction in the stillbirth rate.

Identifying the high-risk fetus in the low-risk pregnant mother (LRM) is a neglected area of research. Fetal growth restriction (FGR) is a major cause of stillbirths, especially in low- and middle-income countries (LMICs). FGR is very poorly detected particularly in healthy pregnant women classified as low risk. Umbiflow is an inexpensive continuous-wave Doppler ultrasound (CWDU) apparatus that is suitable for use by low-level health care providers for screening low-risk pregnant populations. It can easily detect umbilical artery blood flow in the cord, which correlates well with placental function, and poor placental function correlates well with FGR.

Use of CWDU to screen an LMIC population of more than 7,000 LRMs has demonstrated a high prevalence of abnormal umbilical artery flow of 13%, and absent end-diastolic flow, which is associated with end-stage placental disease, was found in 1.2%. This is 10 times higher than previously reported in high-income countries. Screening with CWDU together with a standard protocol managing those pregnancies with abnormal placental blood flow resulted in a 43% reduction in stillbirths (risk ratio: 0.57; 95% confidence interval=0.29, 0.85) in this LRM population. Further, follow-up of infants who had abnormal umbilical artery blood flow showed that these infants had significantly less fat-free mass at ages 6 weeks, 10 weeks, 14 weeks, and 6 months, than those with normal umbilical artery blood flow (P<.015), confirming that CWDU was able to detect true FGR.

Thus, screening with CWDU can detect the fetus at risk of stillbirth, and infants likely to have suboptimal growth and development postnatally. Screening with CWDU in LRMs opens the door to a step change in preventing stillbirths in LMICs.

Risk of recurrent stillbirth and neonatal mortality: mother-specific random effects analysis using longitudinal panel data from Indonesia (2000 - 2014)

Background

Despite significant government investments to improve birth outcomes in low and middle-income countries over the past several decades, stillbirth and neonatal mortality continue to be persistent public health problems. While they are different outcomes, there is little evidence regarding their shared and unique population-level risk factors over a mother’s reproductive lifespan. Data gaps and measurement challenges have left several areas in this field unexplored, especially assessing the risk of stillbirth or neonatal mortality over successive pregnancies to the same woman. This study aimed to assess the risk of stillbirth and neonatal mortality in Indonesia during 2000–2014, using maternal birth histories from the Indonesia Family Life Survey panel data.

Methods

Data from three panels were combined to create right-censored birth histories. There were 5,002 unique multiparous mothers with at least two singleton births in the sample. They reported 12,761 total births and 12,507 live births. Random effects (RE) models, which address the dependency of variance in births to the same mother, were fitted assuming births to the same mother shared unobserved risk factors unique to the mother.

Results

The main finding was that there having had a stillbirth increased the odds of another stillbirth nearly seven-fold and that of subsequent neonatal mortality by over two-fold. Having had a neonatal death was not associated with a future neonatal death. Mothers who were not educated and nullipara were much more likely to experience a neonatal death while mothers who had a prior neonatal death had no risk of another neonatal death due to unmeasured factors unique to the mother.

Conclusions

The results suggest that for stillbirths, maternal heterogeneity, as explained by a prior stillbirth, could capture underlying pathology while the relationship between observed risk factors and neonatal mortality could be much more dependent on context. Establishing previous adverse outcomes such as neonatal deaths and stillbirth could help identify high-risk pregnancies during prenatal care, inform interventions, and improve health policy.

Do and psychometric validation of the perinatal bereavement care competence scale for midwives

PURPOSE

To develop a scale for measuring the perinatal bereavement care competence of midwives and assess its psychometric properties.

METHODS

The Perinatal Bereavement Care Competence Scale (PBCCS) was developed in four phases. 1) Item generation: 75 items were formulated based on a literature review and interviews with midwives. 2) Delphi expert consultation: 15 experts evaluated whether the items were clear/appropriate/relevant to the questionnaire dimensions and the items were optimized. 3) Pilot test: the comprehensibility, acceptability, and time required to complete the questionnaire by midwives were assessed. 4) Evaluation of reliability and validity: the scale was validated by initial item analysis, exploratory and confirmatory factor analyses (EFA and CFA, respectively), and internal consistency reliability and test-retest reliability.

RESULTS

The final scale consisted of six dimensions and 25 items: Maintaining belief (3 items), Knowing (4 items), Being with (6 items), Preserving dignity (4 items), Enabling (5 items) and Self-adjustment (3 items). EFA yielded a 6-factor structure that was consistent with the theoretical framework and explained 70.87% of the total variance. CFA indicated a good fit for the 6-factor model. Cronbach's α for the scale was 0.931 and the test-retest reliability coefficient was 0.968.

CONCLUSION

The PBCCS is a valid and reliable instrument for measuring the competence of midwives in caring for bereaved parents who have experienced perinatal loss.

"Your heart keeps bleeding": lived experiences of parents with a perinatal death in Northern Uganda

Background

Worldwide, two million babies are stillborn and 1.8 million babies die before completing seven days of life. Approximately 4% of pregnant women in Uganda experience perinatal death. The response following a perinatal death tends to be socio-culturally constructed. Investigating the unique personal experiences of parents from a low-income setting with unique cultural beliefs and practices is crucial for the design and implementation of appropriate interventions.

Objective

To describe the lived experiences of parents following perinatal death in Lira district, Northern Uganda.

Methods

A qualitative study was carried out drawing on the tenets of descriptive phenomenology. We conducted 32 in-depth interviews in Lira district, Northern Uganda between August 2019 and September 2020 with 18 women and 14 men who had experienced a stillbirth or an early neonatal death within the preceding 2 years. Participants were selected from different families and interviewed. A local IRB approved the study. All in-depth interviews were audio-recorded, transcribed, translated, and data were analysed using a content thematic approach. Key findings were discussed based on Worden’s Four Tasks of Mourning theory.

Results

The themes that emerged from the analyses included reaction to the perinatal loss and suggestions for support. The participants’ immediate reactions were pain, confusion, and feelings of guilt which were aggravated by the unsupportive behaviour of health care providers. Men cumulatively lost financial resources in addition to facing multiple stressful roles. Delayed reactions such as pain and worries were triggered by the sight of similar-age-babies, subsequent pregnancy losses, and marital challenges. Participants recommended emotional support and management of postnatal complications for parents faced with perinatal loss.

Conclusion

Losing a baby during the perinatal period in a resource-constrained setting negatively affected both gender. In addition, men suffered the loss of financial resources and the burden of multiple stressful roles. Acknowledging the pain and offering support to the grieving parents reinforce their coping with a perinatal loss. In addition to family and community members, health care providers need to provide emotional support and postnatal care to parents who experience perinatal death.

Living with Loss: study protocol for a randomized controlled trial evaluating an internet-based perinatal bereavement program for parents following stillbirth and neonatal death

BACKGROUND

Stillbirth and neonatal death are devastating pregnancy outcomes with long-lasting psychosocial consequences for parents and families, and wide-ranging economic impacts on health systems and society. It is essential that parents and families have access to appropriate support, yet services are often limited. Internet-based programs may provide another option of psychosocial support for parents following the death of a baby. We aim to evaluate the efficacy and acceptability of a self-guided internet-based perinatal bereavement support program "Living with Loss" (LWL) in reducing psychological distress and improving the wellbeing of parents following stillbirth or neonatal death.

METHODS

This trial is a two-arm parallel group randomized controlled trial comparing the intervention arm (LWL) with a care as usual control arm (CAU). We anticipate recruiting 150 women and men across Australia who have experienced a stillbirth or neonatal death in the past 2 years. Participants randomized to the LWL group will receive the six-module internet-based program over 8 weeks including automated email notifications and reminders. Baseline, post-intervention, and 3-month follow-up assessments will be conducted to assess primary and secondary outcomes for both arms. The primary outcome will be the change in Kessler Psychological Distress Scale (K10) scores from baseline to 3-month follow-up. Secondary outcomes include perinatal grief, anxiety, depression, quality of life, program satisfaction and acceptability, and cost-effectiveness. Analysis will use intention-to-treat linear mixed models to examine psychological distress symptom scores at 3-month follow-up. Subgroup analyses by severity of symptoms at baseline will be undertaken.

DISCUSSION

The LWL program aims to provide an evidence-based accessible and flexible support option for bereaved parents following stillbirth or neonatal death. This may be particularly useful for parents and healthcare professionals residing in rural regions where services and supports are limited. This RCT seeks to provide evidence of the efficacy, acceptability, and cost-effectiveness of the LWL program and contribute to our understanding of the role digital services may play in addressing the gap in the availability of specific bereavement support resources for parents following the death of a baby, particularly for men.

Incidence and predictors of paternal anxiety and depression following fetal abnormalities requiring pregnancy termination: a cross-sectional study in China

BACKGROUND

China is a country with a high prevalence of fetal abnormalities. Termination of pregnancy for fetal abnormalities (TOPFA) is a devastating traumatic event for parents and families, resulting in serious and lasting psychological problems. The impact of TOPFA on mothers has been extensively explored, but little research has been conducted on the resulting paternal psychological problems. This study sought to determine the prevalence and predictors of paternal anxiety and depression following TOPFA.

METHODS

We analysed cross-sectional data from 169 Chinese couples (169 mothers and 169 fathers) who experienced TOPFA. Anxiety was assessed with the Self-Rating Anxiety Scale (SAS), and depression was measured with the Self-Rating Depression Scale (SDS) for fathers and the Edinburgh Postnatal Depression Scale (EPDS) for mothers. We used the Social Support Rating Scale (SSRS) to assess levels of social support.

RESULTS

Overall, 19.5% of fathers and 24.3% of mothers had symptoms of anxiety, but there was no significant difference in the incidence of anxiety between fathers and mothers. However, depression was more common in mothers (50.3%) than in fathers (24.9%). Level of income (β = -2.945, 95% CI: -5.448 to -0.442), worry about the pregnancy (β = 3.404, 95% CI: 1.210 to 5.599) and objective support (β = -0.668, 95% CI: -1.163 to -0.173) were predictors of anxiety in fathers. Worry about the pregnancy (β = 4.022, 95% CI: 1.630 to 6.414), objective support (β = -0.652, 95% CI: -1.229 to -0.075) and maternal depression (β = 0.497, 95% CI: 0.159 to 0.836) were predictors of paternal depression.

CONCLUSION

Anxiety and depression were prevalent among parents following TOPFA in China, and fathers had similar levels of anxiety as mothers. Strategies to support fathers should consider social support and psychological interaction and draw upon father-inclusive intervention recommendations.

Abordagem psicossocial às perdas gestacionais na Atenção Primária à Saúde

Introdução: Perdas gestacionais são eventos comuns na vida reprodutiva. Tendo em vista a dificuldade individual e profissional de lidar com o sofrimento mental que ocasionam, indaga-se sobre a escolha da técnica, a periodicidade e o modo de execução das abordagens que melhor se adequariam ao enfrentamento dessa situação. Sendo assim, esta revisão clínica tem como objetivo avaliar a literatura recente acerca do tema e buscar as melhores evidências científicas em relação à abordagem psicossocial a essas perdas. Métodos: Foram utilizadas palavras-chave determinadas pelo Medical Subject Headings (MeSH) para selecionar títulos de estudos nas bases de dados: PubMed, ACCESSSS, British Medical Journal (BMJ), DYNAMED, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Os critérios de inclusão foram: ano de publicação entre 2010 e 2020; tipo de estudo (metanálise, revisão sistemática, ensaio clínico randomizado, ensaio clínico não randomizado, coorte ou caso controle); não abordar abortamento induzido; estar em inglês, português ou espanhol; ser passível de ser encontrado na íntegra. Resultados: Foram encontrados 28 artigos, que tiveram seus resumos avaliados; 14 foram excluídos e 14 lidos na íntegra. No fim, nove estudos foram incluídos nesta revisão. Foi possível observar que sintomas psicológicos são frequentemente apresentados após perdas gestacionais, que há diversas maneiras de acessar esses dados e que não há consenso sobre qual a melhor intervenção a ser feita. Além disso, em homens e casais homossexuais, há maior chance de invisibilidade do sofrimento e menor abordagem de luto por profissionais de saúde. Conclusão: Na falta de consenso sobre quais intervenções apresentam melhores resultados, recomenda-se o rastreamento de sofrimento mental e o compartilhamento da decisão com as partes envolvidas.

Bereavement photography, volunteering, and posttraumatic growth: A mixed-methods investigation

Bereavement photography has been recognized as an important tool to create memories and as a support service for parents experiencing perinatal loss. This paper explores the impact of volunteering on posttraumatic growth among photographers working with parents impacted by stillbirth. Using a mixed-methods design, 141 Australian and New Zealand volunteer bereavement photographers were recruited. Higher number of losses experienced by photographers were correlated with a higher level of posttraumatic growth. Volunteering was associated with an enhanced understanding of loss, increased empathy for bereaved parents, developing effective coping skills and a renewed appreciation of photography. Implications of the findings are discussed.

Chronic Inflammatory Placental Disorders Associated With Recurrent Adverse Pregnancy Outcome

Chronic inflammatory placental disorders are a group of rare but devastating gestational syndromes associated with adverse pregnancy outcome. This review focuses on three related conditions: villitis of unknown etiology (VUE), chronic histiocytic intervillositis (CHI) and massive perivillous fibrin deposition (MPFD). The hallmark of these disorders is infiltration of the placental architecture by maternal immune cells and disruption of the intervillous space, where gas exchange between the mother and fetus occurs. Currently, they can only be detected through histopathological examination of the placenta after a pregnancy has ended. All three are associated with a significant risk of recurrence in subsequent pregnancies. Villitis of unknown etiology is characterised by a destructive infiltrate of maternal CD8+ T lymphocytes invading into the chorionic villi, combined with activation of fetal villous macrophages. The diagnosis can only be made when an infectious aetiology has been excluded. VUE becomes more common as pregnancy progresses and is frequently seen with normal pregnancy outcome. However, severe early-onset villitis is usually associated with fetal growth restriction and recurrent pregnancy loss. Chronic histiocytic intervillositis is characterised by excessive accumulation of maternal CD68+ histiocytes in the intervillous space. It is associated with a wide spectrum of adverse pregnancy outcomes including high rates of first-trimester miscarriage, severe fetal growth restriction and late intrauterine fetal death. Intervillous histiocytes can also accumulate due to infection, including SARS-CoV-2, although this infection-induced intervillositis does not appear to recur. As with VUE, the diagnosis of CHI requires exclusion of an infectious cause. Women with recurrent CHI and their families are predisposed to autoimmune diseases, suggesting CHI may have an alloimmune pathology. This observation has driven attempts to prevent CHI with a wide range of maternal immunosuppression. Massive perivillous fibrin deposition is diagnosed when >25% of the intervillous space is occupied by fibrin, and is associated with fetal growth restriction and late intrauterine fetal death. Although not an inflammatory disorder per se, MPFD is frequently seen in association with both VUE and CHI. This review summarises current understanding of the prevalence, diagnostic features, clinical consequences, immune pathology and potential prophylaxis against recurrence in these three chronic inflammatory placental syndromes.

Awareness of fetal movements and care package to reduce fetal mortality (AFFIRM): a trial-based and model-based cost-effectiveness analysis from a stepped wedge, cluster-randomised trial

Background

The AFFIRM intervention aimed to reduce stillbirth and neonatal deaths by increasing awareness of reduced fetal movements (RFM) and implementing a care pathway when women present with RFM. Although there is uncertainty regarding the clinical effectiveness of the intervention, the aim of this analysis was to evaluate the cost-effectiveness.

Methods

A stepped-wedge, cluster-randomised trial was conducted in thirty-three hospitals in the United Kingdom (UK) and Ireland. All women giving birth at the study sites during the analysis period were included in the study. The costs associated with implementing the intervention were estimated from audits of RFM attendances and electronic healthcare records. Trial data were used to estimate a cost per stillbirth prevented was for AFFIRM versus standard care. A decision analytic model was used to estimate the costs and number of perinatal deaths (stillbirths + early neonatal deaths) prevented if AFFIRM were rolled out across Great Britain for one year. Key assumptions were explored in sensitivity analyses.

Results

Direct costs to implement AFFIRM were an estimated £95,126 per 1,000 births. Compared to standard care, the cost per stillbirth prevented was estimated to be between £86,478 and being dominated (higher costs, no benefit). The estimated healthcare budget impact of implementing AFFIRM across Great Britain was a cost increase of £61,851,400/year.

Conclusions

Perinatal deaths are relatively rare events in the UK which can increase uncertainty in economic evaluations. This evaluation estimated a plausible range of costs to prevent baby deaths which can inform policy decisions in maternity services.

Trial registration

The trial was registered with www.ClinicalTrials.gov, number NCT01777022.

Is care of stillborn babies and their parents respectful? Results from an international online survey

OBJECTIVE

To quantify parents' experiences of respectful care around stillbirth globally.

DESIGN

Multi-country, online, cross-sectional survey.

SETTING AND POPULATION

Self-identified bereaved parents (n = 3769) of stillborn babies from 44 high- and middle-income countries.

METHODS

Parents' perspectives of seven aspects of care quality, factors associated with respectful care and seven bereavement care practices were compared across geographical regions using descriptive statistics. Respectful care was compared between country-income groups using multivariable logistic regression.

MAIN OUTCOME MEASURES

Self-reported experience of care around the time of stillbirth.

RESULTS

A quarter (25.4%) of 3769 respondents reported disrespectful care after stillbirth and 23.5% reported disrespectful care of their baby. Gestation less than 30 weeks and primiparity were associated with disrespect. Reported respectful care was lower in middle-income countries than in high-income countries (adjusted odds ratio 0.35, 95% CI 0.29-0.42, p < 0.01). In many countries, aspects of care quality need improvement, such as ensuring families have enough time with providers. Participating respondents from Latin America and southern Europe reported lower satisfaction across all aspects of care quality compared with northern Europe. Unmet need for memory-making activities in middle-income countries was high.

CONCLUSIONS

Many parents experience disrespectful care around stillbirth. Provider training and system-level support to address practical barriers are urgently needed. However, some practices (which are important to parents) can be readily implemented such as memory-making activities and referring to the baby by name.

The unspoken grief of multiple stillbirths in rural Pakistan: an interpretative phenomenological study

Background

Pakistan has the highest rate of stillbirth (30.6 stillbirths per 1000 total births) as compared to other South Asian countries. The psychological impact of stillbirths on bereaved women is well documented; however, there is a dearth of literature on lived experiences of women with multiple stillbirths in Pakistan.

Objective

The purpose of this research is to understand the lived experiences of women who had multiple stillbirths in Thatta, Pakistan.

Methods

An interpretative phenomenological study was conducted in district Thatta with eight women who experienced more than one stillbirth. A semi-structured in-depth interview guide was used for data collection. The data were analyzed by using thematic analysis approach.

Results

The results of this study show that experiencing multiple stillbirths has a devastating impact on women’s mental and social wellbeing. The women who experienced multiple stillbirths are stigmatized as “child-killer” or cursed or being punished by God. They are avoided in social gatherings within the families and community, because of these social pressures these women seek spiritual and religious treatment, and struggle to conceive again to deliver a live baby. It was observed that the psycho-social and medical needs of these bereaved women remain unaddressed not only by the healthcare system but also by the society at large.

Conclusions

The physical, social and mental well-being of women who experience multiple stillbirth are at stake. These women are being considered social outcast. Health care providers including physicians, lady health workers, and traditional birth attendants should be trained on provision of psychosocial support along with the routine care that they provide in communities and health facilities. The health care providers should also inform the bereaved women about the biomedical causes of stillbirths that would be helpful to mitigate the stigma associated with stillbirths. Moreover, the health care providers should also counsel family members especially in-laws of these sorrowful women about the biomedical causes of stillbirths that would also be helpful to mitigate the stigma associated with stillbirths.

Milk Donation Following A Perinatal Loss: A Phenomenological Study

INTRODUCTION

Perinatal loss is a traumatic event for women with negative consequences for their well-being and mental health. After perinatal loss, some women choose to not suppress lactation and to donate their breast milk. Donating milk can be a grief ritual to cope with the loss. The aim of this study was to explore women's experiences of donating their breast milk following a perinatal loss.

METHODS

A hermeneutic phenomenology was carried out. Thirteen semistructured interviews were conducted. Data was recorded, transcribed, and categorized into themes and subthemes.

RESULTS

Two main themes emerged from the data: (1) lactation after loss: a forgotten aspect of the care, with the subthemes "the silence surrounding grieving lactation" and "experiencing lactation amidst a sea of tears"; and (2) milk donation: a resource to alleviate pain and offer hope, with the subthemes "expressing and donating breast milk: a healing ritual" and "breaking the taboo of the grieving lactation."

DISCUSSION

Information about lactation options is not typically included in participants' care plan. Women's experiences highlight the need for the support of health care professionals. Donating milk helps some women to cope with the loss and accept and integrate it into their daily lives. Milk donation is also an opportunity to educate society about options following a perinatal loss.

Protocol for the development of a core outcome set for stillbirth care research (iCHOOSE Study)

INTRODUCTION

Stillbirth is associated with significant physical, psychosocial and economic consequences for parents, families, wider society and the healthcare system. There is emerging momentum to design and evaluate interventions for care after stillbirth and in subsequent pregnancies. However, there is insufficient evidence to inform clinical practice compounded by inconsistent outcome reporting in research studies. To address this paucity of evidence, we plan to develop a core outcome set for stillbirth care research, through an international consensus process with key stakeholders including parents, healthcare professionals and researchers.

METHODS AND ANALYSIS

The development of this core outcome set will be divided into five distinct phases: (1) Identifying potential outcomes from a mixed-methods systematic review and analysis of interviews with parents who have experienced stillbirth; (2) Creating a comprehensive outcome long-list and piloting of a Delphi questionnaire using think-aloud interviews; (3) Choosing the most important outcomes by conducting an international two-round Delphi survey including high-income, middle-income and low-income countries; (4) Deciding the core outcome set by consensus meetings with key stakeholders and (5) Dissemination and promotion of the core outcome set. A parent and public involvement panel and international steering committee has been convened to coproduce every stage of the development of this core outcome set.

ETHICS AND DISSEMINATION

Ethical approval for the qualitative interviews has been approved by Berkshire Ethics Committee REC Reference 12/SC/0495. Ethical approval for the think-aloud interviews, Delphi survey and consensus meetings has been awarded from the University of Bristol Faculty of Health Sciences Research Ethics Committee (Reference number: 116535). The dissemination strategy is being developed with the parent and public involvement panel and steering committee. Results will be published in peer-reviewed specialty journals, shared at national and international conferences and promoted through parent organisations and charities.

Grief in women with previous miscarriage or stillbirth: a systematic review of cross-sectional and longitudinal prospective studies

Background: Women who have had miscarriages or stillbirths are known to have a high risk for enduring grief. However, the course and frequency of enduring grief in this subgroup are not fully understood. Objective: Our aims were to assess the intensity of grief and its course in women with miscarriages or stillbirths and to estimate the frequency of severe grief reactions in this population. Additionally, we compared subgroups with miscarriages versus stillbirths and with single versus recurrent pregnancy loss. Method: A systematic literature search of the databases MEDLINE, psycINFO and PSYNDEX was conducted to consider all studies published between 2000 and 31 March 2022 in English or German on the prevalence and intensity of grief in women who had miscarriages or stillbirths. Studies that used validated assessment methods were included in this systematic review. The PRISMA guidelines were followed. Results: Study characteristics and grief data were extracted independently by two investigators from 13 cross-sectional and eight longitudinal studies from 11 countries (N = 2597). All studies used self-reporting instruments. According to 17 of 21 studies (81%), grief is markedly elevated in women after miscarriages or stillbirths. The studies are very heterogeneous regarding the samples, the length of pregnancies and the time of assessment regarding grief after miscarriages. Most studies document intense grief and frequent severe grief reactions - with a decrease over time - in women who have had miscarriages or stillbirths. Clear conclusions regarding corresponding differences between women with miscarriages and stillbirths or single and recurrent pregnancy losses cannot be drawn. Conclusions: Pronounced grief is frequent in women who had miscarriages or stillbirths. More longitudinal studies are needed to examine the course of grief in this group and to identify those women who develop prolonged grief disorder, depression or other mental-health problems.

Determinants for Perinatal Mortality in South China: A Prospective Cohort Study

OBJECTIVE

To estimate the association of selected maternal and fetal characteristics with the risk of perinatal mortality in South China.

METHODS

A prospective cohort study was conducted from March 2013 to December 2019. The exposures of interest were maternal sociodemographic characteristics, lifestyle and habits during early pregnancy, and complications of pregnancy. Their effects on the development of perinatal death were analyzed in our study.

RESULTS

A total of 44,048 eligible pregnant women were included in the analysis. Of these, 596 fetuses were perinatal deaths (perinatal mortality was 13.5 per 1,000 births). After adjustment, maternal obesity, being employed, history of gestational hypertension, taking antidepressants during early pregnancy, history of gestational diabetes mellitus, gestational diabetes mellitus, infertility drug treatment and assisted reproductive techniques, history of neonatal death, preterm birth, and congenital malformations all significantly increased the risk of perinatal death. Ethnic minority, income > 5,000, multiparous women, and cesarean section associated with reduced risk of perinatal death.

CONCLUSION

Some factors of maternal sociodemographic characteristics, abnormal pregnancy history, lifestyle and habits during early pregnancy, and complications of pregnancy were associated with the risk of perinatal death.

Infants' prenatal exposure to opioids and the association with birth outcomes: A systematic review and meta-analysis

BACKGROUND

Prenatal exposure to opioids (PEO) is a worldwide public health issue. Opioids cross the placental barrier and may affect the developing foetus and the birth outcomes.

OBJECTIVES

This review aimed to explore newborns' weight, length and head circumference, preterm birth, and perinatal death as primary outcomes in relation to PEO. The secondary outcomes were gestational age at birth, Apgar scores and length of hospitalisation after delivery.

DATA SOURCES

PubMed, Embase, PsycInfo and the Web of Science.

STUDY SELECTION AND DATA EXTRACTION

Inclusion criteria were (i) cohort, case-control or cross-sectional peer-reviewed studies published in English through 1 March 2021; (ii) comparing outcomes between prenatal exposed and unexposed groups to opioids (prescribed or obtained illegally). Exclusion criteria were foetal alcohol syndrome and non-opioid primary exposure.

SYNTHESIS

Data were extracted by two authors. The Newcastle-Ottawa Quality Assessment Scale was used for study quality assessment. Due to heterogeneity across studies, we used random effects models to obtain pooled standardised mean difference (SMD), pooled risk ratio (RR) and 95% confidence interval (CI).

RESULTS

Data from 80 studies were extracted. In meta-analyses, opioid-exposed neonates had lower birthweight (SMD -0.77, 95% CI -0.90, -0.64, I²  = 82%), smaller head circumference (SMD -0.67, 95% CI -0.86, -0.48, I²  = 84%), shorter birth length (SMD -0.97, 95% CI -1.24, -0.70, I²  = 91%) and gestational age (SMD -0.45, 95% CI -0.60, -0.30, I²  = 80%) than unexposed neonates. Pooled risks of neonatal death and preterm birth were higher among opioid-exposed compared to unexposed neonates (RR 4.05, 95% CI 2.12, 7.72, I²  = 73%; and RR 1.92, 95% CI 1.57, 2.35, I²  = 99%).

CONCLUSIONS

We found increased risks of adverse birth outcomes in relation to PEO. Caution should be used in interpreting the findings, as many studies were rated as poor quality, and with substantial inter-study heterogeneity. Future studies should ensure comparability of opioid-exposed and -unexposed group to strengthen internal validity.

Experience of undergraduate midwifery students faced with perinatal death in clinical practice: A qualitative study

BACKGROUND

Student midwives often encounter perinatal loss including stillbirth and neonatal death as part of their clinical training. There has been limited research on how student midwives cope with perinatal death.

OBJECTIVE

To explore the experiences of undergraduate midwifery students facing perinatal death during their internships.

DESIGN

Qualitative research design based on interpretive phenomenological approach and COREQ-guided reporting.

SETTING

Tertiary maternal and child care center or general hospital.

PARTICIPANTS

Undergraduate midwifery students from a medical university in Guangzhou, China.

METHODS

Study participants were recruited through purposive sampling. Semi-structured in-depth interviews were conducted between October 2020 and March 2021 with 12 midwifery students. Transcripts of the interviews were analyzed using Diekelmann's interpretive method.

RESULTS

Four themes were identified from the data: unavoidable anxiety and avoidance response; overwhelming fear and taboos related to death; self-blame and emotional inhibition; and ethical conflict and reflection on practice.

CONCLUSIONS

Undergraduate midwifery students believed they were ill-prepared to care for women who experienced perinatal loss, consciously endured their own negative emotions such as anxiety and fear, and hoped for improved bereavement and stillbirth care in future clinical practice. Students valued support from the bereavement midwife and identified effective strategies that would help them cope with their feelings. It is recommended that adequate education and emotional support be provided to midwifery students, who should be encouraged to provide appropriate care to grieving families.

Preliminary findings on the experiences of care for parents who suffered perinatal bereavement during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic poses an unprecedented risk to the global population. Maternity care in the UK was subject to many iterations of guidance on how best to reconfigure services to keep women, their families and babies, and healthcare professionals safe. Parents who experience a pregnancy loss or perinatal death require particular care and support. PUDDLES is an international collaboration investigating the experiences of recently bereaved parents who suffered a late miscarriage, stillbirth, or neonatal death during the global COVID-19 pandemic, in seven countries. In this study, we aim to present early findings from qualitative work undertaken with recently bereaved parents in the United Kingdom about how access to healthcare and support services was negotiated during the pandemic.

METHODS

In-depth semi-structured interviews were undertaken with parents (N = 24) who had suffered a late miscarriage (n = 5; all mothers), stillbirth (n = 16; 13 mothers, 1 father, 1 joint interview involving both parents), or neonatal death (n = 3; all mothers). Data were analysed using a template analysis with the aim of investigating bereaved parents' access to services, care, and networks of support, during the pandemic after their bereavement.

RESULTS

All parents had experience of utilising reconfigured maternity and/or neonatal, and bereavement care services during the pandemic. The themes utilised in the template analysis were: 1) The Shock & Confusion Associated with Necessary Restrictions to Daily Life; 2) Fragmented Care and Far Away Families; 3) Keeping Safe by Staying Away; and 4) Impersonal Care and Support Through a Screen. Results suggest access to maternity, neonatal, and bereavement care services were all significantly reduced, and parents' experiences were notably affected by service reconfigurations.

CONCLUSIONS

Our findings, whilst preliminary, are important to document now, to help inform care and service provision as the pandemic continues and to provide learning for ongoing and future health system shocks. We draw conclusions on how to enable development of safe and appropriate services during this pandemic and any future health crises, to best support parents who experience a pregnancy loss or whose babies die.

Measures of anxiety, depression and stress in the antenatal and perinatal period following a stillbirth or neonatal death: a multicentre cohort study

BACKGROUND

The grief associated with the death of a baby is enduring, however most women embark on another pregnancy, many in less than a year following their loss. Symptoms of anxiety and depression are reported to be increased in pregnancies after perinatal death, although effect on maternal stress is less clear. Variation between individual studies may result from differences in gestation at sampling, the questionnaire used and the type of antecedent perinatal death. We aimed to describe quantitative measures of anxiety, depression, stress and quality of life at different timepoints in pregnancies after perinatal death and in the early postnatal period.

METHODS

Women recruited from three sites in the North-West of England. Women were asked to participate if a previous pregnancy had ended in a perinatal death. Participants completed validated measures of psychological state (Cambridge Worry Score, Edinburgh Postnatal Depression Score (EPDS), Generalized Anxiety Disorder 7-item score) and health status (EQ-5D-5L™ and EQ5D-Visual Analogue Scale) at three time points, approximately 15 weeks' and 32 weeks' gestation and 6 weeks postnatally. A sample of hair was taken at approximately 36 weeks' gestation for measurement of hair cortisol in a subgroup of women. The hair sample was divided into samples from each trimester and cortisol measured by ELISA.

RESULTS

In total 112 women participated in the study. Measures of anxiety and depressive symptoms decreased from the highest levels at 15 weeks' gestation to 6-weeks postnatal (for example mean GAD-7: 15 weeks 8.2 ± 5.5, 6 weeks postnatal 4.4 ± 5.0, p<0.001). Hair cortisol levels fell in a similar profile to anxiety and depression symptoms (p<0.05). In contrast, the median EQ-5D index, measuring health status was 0.768 at 15 weeks' gestation (Interquartile range (IQR) 0.684-0.879), 0.696 at 32 weeks' (IQR 0.637-0.768) and 0.89 (0.760-1.00) at 6 weeks postnatal. There was a negative relationship between EPDS and perceived health status.

CONCLUSIONS

This study demonstrated heightened anxiety and depressive symptoms and elevated cortisol levels in women in pregnancies after a stillbirth or neonatal death which decrease as pregnancy progresses. Further studies are needed to determine optimal care for women to address these negative psychological consequences.

Pitfalls of International Classification of Diseases - Perinatal mortality in analysing stillbirths

OBJECTIVES

This study aimed to evaluate the trend of stillbirth from 2009 to 2018. The causes of stillbirth were classified using the International Classification of Diseases - Perinatal Mortality (ICD-PM).

STUDY DESIGN AND METHODS

A retrospective chart review was performed on 135 stillbirths from 2009 to 2018 in a tertiary university teaching hospital. The annual stillbirth rate was calculated, and the trend was evaluated. The cause of death was reclassified using ICD-PM.

RESULTS

The stillbirth rate was 3.70 per 1000 total births, and it remained stable over the studied period (P = 0.238). Most of the stillbirth (97.8%) were antepartum deaths. The proportion of unexplained stillbirth was reduced from 57% to 18.5% after reclassified by ICD-PM coding. Another major cause of antepartum stillbirths was disorders related to fetal growth, which consisted of mothers with medical and surgical conditions (11%, n = 15, ICD-PM code A5, M4) or mothers with complications of placenta, cord and membranes (8.9%, n = 12, ICD-PM code A5, M1).

CONCLUSION

The use of ICD-PM was useful in reducing the proportion of unexplained stillbirths. ICD-PM has the advantages of coding related to the timing of stillbirth and associated maternal conditions. Pitfalls including the unclear use of the code A3-'antepartum hypoxia,' guidance on coding of well-controlled maternal medical conditions and placental pathology and the importance of subcategorisation need to be addressed.

Adverse pregnancy outcomes attributable to socioeconomic and ethnic inequalities in England: a national cohort study

BACKGROUND

Socioeconomic deprivation and minority ethnic background are risk factors for adverse pregnancy outcomes. We aimed to quantify the magnitude of these socioeconomic and ethnic inequalities at the population level in England.

METHODS

In this cohort study, we used data compiled by the National Maternity and Perinatal Audit, based on birth records from maternity information systems used by 132 National Health Service hospitals in England, linked to administrative hospital data. We included women who gave birth to a singleton baby with a recorded gestation between 24 and 42 completed weeks. Terminations of pregnancy were excluded. We analysed data on stillbirth, preterm birth (<37 weeks of gestation), and fetal growth restriction (FGR; liveborn with birthweight <3rd centile by the UK definition) in England, and compared these outcomes by socioeconomic deprivation quintile and ethnic group. We calculated attributable fractions for the entire population and specific groups compared with least deprived groups or White women, both unadjusted and with adjustment for smoking, body-mass index (BMI), and other maternal risk factors.

FINDINGS

We identified 1 233 184 women with a singleton birth between April 1, 2015, and March 31, 2017, of whom 1 155 981 women were eligible and included in the analysis. 4505 (0·4%) of 1 155 981 births were stillbirths. Of 1 151 476 livebirths, 69 175 (6·0%) were preterm births and 22 679 (2·0%) were births with FGR. Risk of stillbirth was 0·3% in the least socioeconomically deprived group and 0·5% in the most deprived group (p<0·0001), risk of a preterm birth was 4·9% in the least deprived group and 7·2% in the most deprived group (p<0·0001), and risk of FGR was 1·2% in the least deprived group and 2·2% in the most deprived group (p<0·0001). Population attributable fractions indicated that 23·6% (95% CI 16·7-29·8) of stillbirths, 18·5% (16·9-20·2) of preterm births, and 31·1% (28·3-33·8) of births with FGR could be attributed to socioeconomic inequality, and these fractions were substantially reduced when adjusted for ethnic group, smoking, and BMI (11·6% for stillbirths, 11·9% for preterm births, and 16·4% for births with FGR). Risk of stillbirth ranged from 0·3% in White women to 0·7% in Black women (p<0·0001); risk of preterm birth was 6·0% in White women, 6·5% in South Asian women, and 6·6% in Black women (p<0·0001); and risk of FGR ranged from 1·4% in White women to 3·5% in South Asian women (p<0·0001). 11·7% of stillbirths (95% CI 9·8-13·5), 1·2% of preterm births (0·8-1·6), and 16·9% of FGR (16·1-17·8) could be attributed to ethnic inequality. Adjustment for socioeconomic deprivation, smoking, and BMI only had a small effect on these ethnic group attributable fractions (13·0% for stillbirths, 2·6% for preterm births, and 19·2% for births with FGR). Group-specific attributable fractions were especially high in the most socioeconomically deprived South Asian women and Black women for stillbirth (53·5% in South Asian women and 63·7% in Black women) and FGR (71·7% in South Asian women and 55·0% in Black women).

INTERPRETATION

Our results indicate that socioeconomic and ethnic inequalities were responsible for a substantial proportion of stillbirths, preterm births, and births with FGR in England. The largest inequalities were seen in Black and South Asian women in the most socioeconomically deprived quintile. Prevention should target the entire population as well as specific minority ethnic groups at high risk of adverse pregnancy outcomes, to address risk factors and wider determinants of health.

Depression, anxiety, PTSD, and OCD after stillbirth: a systematic review

BACKGROUND

This systematic review aimed to provide an updated summary of studies investigating depression, anxiety, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD) in parents after stillbirth (from 20 weeks gestational age until birth).

METHODS

A literature search was conducted in the databases Web of Science and PsychINFO. Main inclusion criteria were 1) peer-reviewed, quantitative, English-language articles published from 1980; (2) studies investigating depression, anxiety, PTSD, or OCD among parents following stillbirth; and (3) studies defining stillbirth as equal to or after 20 weeks of gestation.

RESULTS

Thirteen quantitative, peer-reviewed articles were eligible for inclusion. Selected articles investigated depression, anxiety, and PTSD, while no studies on OCD met our inclusion criteria. The majority of studies investigated women, while only two studies included men. The results indicated heightened short- and long-term levels of depression, anxiety, and PTSD in parents after stillbirth compared to those of parents with live birth. Studies investigating predictors found that social support, marital status, negative appraisals, and variables related to care and management after stillbirth affected levels of symptoms.

CONCLUSIONS

Parents who experience stillbirth have a considerably higher risk of reporting symptoms of depression, anxiety, and PTSD compared with parents with live births. More longitudinal studies are needed to increase our knowledge of how symptoms develop over time, and more research on fathers, transgender, non-binary and gender fluid individuals is needed. Research on the association between stillbirth and OCD is also warranted. Knowledge of the severity of anxiety, depression, and PTSD after stillbirth, and predictors associated with symptom severity could provide healthcare professionals with valuable information on how to provide beneficial postpartum care.

"Getting it right when it goes wrong - Effective bereavement care requires training of the whole maternity team"

Stillbirth or neonatal death is one of the most traumatic and distressing life experiences with negative psychosocial effects. Perinatal grief is natural and understandable, and, if not recognized and well supported, may lead to long-term harmful effects. Harm may also be caused to the other surviving siblings, families, and next generation. This can be helped by effective bereavement care. Bereavement care is an area of enormous needs, relatively untraveled road. Though the loss cannot be undone, but a negative impact can be minimized by compassionate supportive care. This chapter will focus on the need of a trained team for effective bereavement care. Principles of evidence-based best practices from the literature will be reviewed and translated into key practice implications. An emphasis is laid on a structured training involving the whole team. We hope this will help in day-to-day situation handling so as to prevent the harm associated with unaddressed grief. Areas of gap with the further need of research are highlighted.

Ethnic variation in causes of stillbirth in high income countries: A systematic review and meta-analysis

OBJECTIVE

Inequities in stillbirth rate according to ethnicity persist in high income nations. The objective of the present study is to investigate whether causes of stillbirth differ by ethnicity in high-income nations.

METHODS

The following databases were searched since their inception to 1 February 2021: Medline, Embase, Scopus, CINAHL, Cochrane Library, and Global Health. Cohort, cross-sectional, and retrospective studies were included. Causes of stillbirth were aligned to the International Classification of Disease 10 for Perinatal Mortality (ICD10-PM) and pooled estimates were derived by meta-analysis.

RESULTS

Fifteen reports from three countries (72 555 stillbirths) were included. Seven ethnic groups - "Caucasian" (n = 11 studies), "African" (n = 11 studies), "Hispanic" (n = 7 studies), "Indigenous Australian" (n = 4 studies), "Asian" (n = 2 studies), "South Asian" (n = 2 studies), and "American Indian" (n = 1 study) - were identified. There was an overall paucity of recent, high-quality data for many ethnicities. For those with the greatest amount of data - Caucasian, African, and Hispanic - no major differences in the causes of stillbirth were identified.

CONCLUSION

There is a paucity of high-quality information on causes of stillbirth for many ethnicities. Improving investigation and standardizing classification of stillbirths is needed to assess whether causes of stillbirth differ across more diverse ethnic groups.

Association between Maternal Exposure to Chemicals during Pregnancy and the Risk of Foetal Death: The Japan Environment and Children's Study

Scarce knowledge is available on the relationship between maternal chemical exposure during pregnancy and foetal deaths. We studied the association of spontaneous abortions and stillbirths with occupational or daily maternal exposure to chemicals commonly used by pregnant women. Data from the Japan Environment and Children’s Study (JECS), a nationwide prospective birth cohort study, were used. The participants of the study were asked about the frequency of their use of gasoline, pesticides, hair dye, and chlorine bleach during the first and the second to third trimesters of pregnancy. We investigated the relationship between the frequency of the use of chemicals and foetal death. Of the 104,065 foetuses, 923 (0.91%) were spontaneous abortions and 379 (0.37%) were stillbirths. Any type of exposure during the first trimester was not significantly associated with spontaneous abortions. Nevertheless, a more than weekly occupational use of hair dye from the first to the second/third trimester was significantly associated with stillbirth. The results of this study suggest that the frequent use of hair dye during pregnancy can have severe adverse effects on the foetus. These findings can help pregnant women, especially hairdressers, refrain from the continuous use of hair dyes.

Association between preconceptional air pollution exposure and medical purposes for selective termination of pregnancy

BACKGROUND

Exposure to air pollutants is associated with adverse pregnancy outcomes. But evidence on the effects of preconceptional air pollution exposure on the risk of termination of pregnancy (TOP) caused by pregnancy losses and congenital malformations is lacking.

METHODS

The distributed lag nonlinear model (DLNM) was used to evaluate the impact of short-term air pollutants exposure on the risk of TOP. Stratified analyses by age (<35 years old, ≥ 35 years old) and season (warm season, cold season) were further conducted. Relative risk (RR) and 95 % confidential interval (95 % CI) were calculated for per interquartile range (IQR) increment in air pollutants during the study period.

RESULTS

PM_2.5, PM₁₀, and O₃ exposure were significantly associated with elevated risk of TOP. The risk of TOP was associated with PM_2.5 exposure from lag11 to lag15 in the single-pollutant model, and the strongest association was observed at lag13 (RR = 1.021, 95%CI:1.002-1.040). PM₁₀ exposure from lag10 to lag15 was associated with increased TOP risk, with the corresponding peak association being at lag13 (RR = 1.020, 95%CI: 1.004-1.037). For O₃, the single-day lag association appeared to be statistically significant from lag26 to lag27, with the highest RR of TOP cases being at lag27 (RR = 1.044, 95%CI: 1.005-1.084). Similar results were observed for pregnancy losses (PL). However, no significantly association between air pollution exposure and the risk of congenital malformations (CM) was found in this study. Stratified analyses showed that pregnant women with more advanced ages were more susceptible to PM_2.5, PM₁₀, and O₃ exposure. The effect of PM_2.5 exposure was statistically significant in cold season subgroups.

CONCLUSION

The findings suggest that exposure to PM_2.5, PM₁₀, and O₃ before pregnancy are associated with the risk of TOP in Lu'an, China, reflecting the significance of preconceptional environmental exposure in the development of adverse pregnancy outcomes.

Maternal exposure to PM2.5 was linked to elevated risk of stillbirth

BACKGROUND

More and more studies began to explore the hazardous health effects of PM_2.5, but few reported its impacts on stillbirth. The sparse results were inconsistent and remained to be integrated. Therefore, we aimed to reveal the association between maternal exposure to PM_2.5 and stillbirth.

METHODS

In this meta-analysis, we searched PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for related articles written in English and published before October 18, 2020. Study selection was conducted according to the predetermined criteria and data attraction was done with predesigned form. A new instrument was applied to conduct the risk of bias assessment. And random-effect models were used to pool the estimates.

RESULTS

A total of 3655 records were identified from the databases, but only 7 studies were ultimately included in this study. Positive association was found between the maternal exposure to PM_2.5 (per 10 μg/m³ increased) in the entire pregnancy (OR: 1.15, 95% CI: 1.07-1.25) and third trimester (OR: 1.09, 95% CI: 1.01-1.18) and stillbirth, but the association between the maternal exposure to PM_2.5 (per 10 μg/m³ increased) in the first trimester (OR: 1.01, 95% CI: 0.90-1.13) and second trimester (OR: 1.06, 95% CI: 0.98-1.14) and stillbirth was not statistically significant. Besides, there was no publication bias.

CONCLUSIONS

Maternal exposure to PM_2.5 in the entire pregnancy and third trimester was associated with elevated risk of stillbirth. However, due to the high heterogeneity, further pathophysiological researches and high quality population studies were still warranted.

Racial Disparities in Stillbirth Risk Factors among non-Hispanic Black Women and non-Hispanic White Women in the United States

INTRODUCTION

Historically, stillbirth risk factors are more prevalent among non-Hispanic Black women than non-Hispanic White women, including age < 20, lower formal educational attainment, prepregnancy obesity, smoking, hypertension, diabetes, short interpregnancy interval, small for gestational age newborn, late prenatal care, and previous cesarean birth. We examined whether these disparities have changed since 2011 and identified a group of risk factors that differed between Black women and White women when accounting for correlations among variables.

METHODS

In a random sample of 315 stillbirths from the National Center for Health Statistics' 2016 fetal death data, Black women and White women were compared for each risk factor using t-tests or chi-square tests. Variables with p ≤ .20 were analyzed using multivariate analysis of variance.

RESULTS

In this sample, Black women experiencing stillbirth were less likely to have a Bachelor's degree (12.94% vs. 28.49%, p = .04), and more likely to be obese (44.5% vs. 29.1%, p = .01) than White women. Multivariate analysis accounting for correlations among variables showed a group of risk factors that differed between Black women and White women: age < 20, lower education, prepregnancy obesity, hypertension (chronic and pregnancy-associated), nulliparity before stillbirth, and earlier gestation.

CLINICAL IMPLICATIONS

Less formal education, obesity, age <20, hypertension, chronic and pregnancy-associated, nulliparity, and earlier gestation are important to consider in multilevel stillbirth prevention interventions to decrease racial disparity in stillbirth. Respectfully listening to women and taking their concerns seriously is one way nurses and other health care providers can promote equity in health outcomes for childbearing women.

Healthcare costs of investigations for stillbirth from a population-based study in Australia

Objective Stillbirth investigations incur healthcare costs, but these investigations are necessary to provide information that will help reduce the risk of a recurrent stillbirth, as well as advice regarding family planning and future pregnancies. The aims of this study were to determine the healthcare costs of investigations for stillbirths, identify drivers and assess cost differences between explained and unexplained stillbirths. Methods Data from 697 stillbirths were extracted from the Stillbirth Causes Study covering the period 2013-18. The dataset comprised all investigations related to stillbirth on the mother, baby and placenta. Unit costs applied were sourced from the Australian Medicare Benefits Schedule, local hospital estimates and published literature. Multivariable regression analyses were used to assess key factors in cost estimates. Results In all, 200 (28.7%) stillbirths were unexplained and 76.8% of these had between five and eight core investigations. Unexplained stillbirths were twice as likely to have eight core investigations as explained stillbirths (16.5% vs 7.7%). The estimated aggregated cost of stillbirth investigations for 697 stillbirths was A$2.13 million (mean A$3060, median A$4246). The main cost drivers were autopsies or cytogenetic screening. Mean costs were similar when stillbirths had known or unknown causes and by reason for stillbirth among cases with definable causes. Conclusion Investigations for stillbirth in Australia cost approximately A$4200 per stillbirth on average and are critical for managing future pregnancies and preventing more stillbirths. These findings improve our understanding of the costs that may be averted if stillbirths can be prevented through primary prevention initiatives. What is known about the topic? Approximately 2000 stillbirths occur each year in Australia, and this trend has not changed for several decades. Stillbirth investigations incur healthcare costs, but these investigations are necessary to provide information to help reduce the risk of a recurrent stillbirth and advice regarding family planning and future pregnancies. Recommendations for the core set of stillbirth investigations have recently been agreed upon by consensus. What does this paper add? The costs of stillbirth investigations are unknown in Australia. The assessment of these costs is challenging because not all investigations involved in stillbirths are recorded within formal administrative systems because a stillborn baby is not formally recognised as a patient. The present population-based analysis of 697 stillbirths in Australia estimated that, on average, A$4200 was spent on investigations for each stillbirth, with key drivers being autopsies and cytogenetic screening. These costs are typical, with most cases having between five and eight of the core eight recommended investigations. What are the implications for practitioners? There are cost implications for stillbirth investigations, and this analysis gives a true account of current practice in Australia. Together with the high downstream economic costs of stillbirths, the cost burden of stillbirth investigations is high but ultimately avoidable when practitioners adhere to the core investigations, build knowledge around preventable risk factors and use this information to reduce the number of stillbirths.

Identification of factors associated with stillbirth in Zimbabwe - a cross sectional study

INTRODUCTION

98% of the 2.6 million stillbirths per annum occur in low and middle income countries. However, understanding of risk factors for stillbirth in these settings is incomplete, hampering efforts to develop effective strategies to prevent deaths.

METHODS

A cross-sectional study of eligible women on the postnatal ward at Mpilo Hospital, Zimbabwe was undertaken between 01/08/2018 and 31/03/2019 (n = 1779). Data were collected from birth records for maternal characteristics, obstetric and past medical history, antenatal care and pregnancy outcome. A directed acyclic graph was constructed with multivariable logistic regression performed to fit the corresponding model specification to data comprising singleton pregnancies, excluding neonatal deaths (n = 1734), using multiple imputation for missing data. Where possible, findings were validated against all women with births recorded in the hospital birth register (n = 1847).

RESULTS

Risk factors for stillbirth included: previous stillbirth (29/1691 (2%) of livebirths and 39/43 (91%) of stillbirths, adjusted Odds Ratio (aOR) 2628.9, 95% CI 342.8 to 20,163.0), antenatal care (aOR 44.49 no antenatal care vs. > 4 antenatal care visits, 95% CI 6.80 to 291.19), maternal medical complications (aOR 7.33, 95% CI 1.99 to 26.92) and season of birth (Cold season vs. Mild aOR 14.29, 95% CI 3.09 to 66.08; Hot season vs. Mild aOR 3.39, 95% CI 0.86 to 13.27). Women who had recurrent stillbirth had a lower educational and health status (18.2% had no education vs. 10.0%) and were less likely to receive antenatal care (20.5% had no antenatal care vs. 6.6%) than women without recurrent stillbirth.

CONCLUSION

The increased risk in women who have a history of stillbirth is a novel finding in Low and Middle Income Countries (LMICs) and is in agreement with findings from High Income Countries (HICs), although the estimated effect size is much greater (OR in HICs ~ 5). Developing antenatal care for this group of women offers an important opportunity for stillbirth prevention.

My Baby's Movements: a stepped-wedge cluster-randomised controlled trial of a fetal movement awareness intervention to reduce stillbirths

OBJECTIVE

The My Baby's Movements (MBM) trial aimed to evaluate the impact on stillbirth rates of a multifaceted awareness package (the MBM intervention).

DESIGN

Stepped-wedge cluster-randomised controlled trial.

SETTING

Twenty-seven maternity hospitals in Australia and New Zealand.

POPULATION

Women with a singleton pregnancy without major fetal anomaly at ≥28 weeks of gestation from August 2016 to May 2019.

METHODS

The MBM intervention was implemented at randomly assigned time points, with the sequential introduction of eight groups of between three and five hospitals at 4-monthly intervals. Using generalised linear mixed models, the stillbirth rate was compared in the control and the intervention periods, adjusting for calendar time, study population characteristics and hospital effects.

MAIN OUTCOME MEASURES

Stillbirth at ≥28 weeks of gestation.

RESULTS

There were 304 850 births with 290 105 births meeting the inclusion criteria: 150 053 in the control and 140 052 in the intervention periods. The stillbirth rate was lower (although not statistically significantly so) during the intervention compared with the control period (2.2/1000 versus 2.4/1000 births; aOR 1.18, 95% CI 0.93-1.50; P = 0.18). The decrease in stillbirth rate was greater across calendar time: 2.7/1000 in the first versus 2.0/1000 in the last 18 months. No increase in secondary outcomes, including obstetric intervention or adverse neonatal outcome, was evident.

CONCLUSIONS

The MBM intervention did not reduce stillbirths beyond the downward trend over time. As a result of low uptake, the role of the intervention remains unclear, although the downward trend across time suggests some benefit in lowering the stillbirth rate. In this study setting, an awareness of the importance of fetal movements may have reached pregnant women and clinicians prior to the implementation of the intervention.

TWEETABLE ABSTRACT

The My Baby's Movements intervention to raise awareness of decreased fetal movement did not significantly reduce stillbirth rates.

Pregnancy after stillbirth: maternal and neonatal outcomes and health service utilization

BACKGROUND

Stillbirth occurs in every 3.5 of 1000 pregnancies in Ireland and is a devastating event for a family. Women who have a pregnancy after stillbirth require increased antenatal support.

OBJECTIVE

This study aimed to determine maternal and fetal outcomes and to quantify health service utilization in pregnancy after stillbirth.

STUDY DESIGN

A retrospective cohort study of all pregnancies after stillbirth was conducted from 2011 to 2017 in a large tertiary referral university maternity teaching hospital with approximately 8000 births annually.

RESULTS

There were 222 stillbirths from 2011 to 2017. Two-thirds of women (145 of 222 [64.3%]) had a pregnancy after stillbirth. Almost one-fifth of these women (28 of 145 [19.3%]) had a miscarriage, but 16 of 28 women (57.1%) had a subsequent live birth, giving an overall live birth rate of 90.3% (131/145). The average interval from index loss to booking in the next pregnancy was 13 months, with almost half of the women (72 of 145 [49.7%]) booking within 1 year. The average number of antenatal appointments was twice than expected (10; range, 2-27), and the average number of ultrasound scans was 5 times higher than expected (5; range, 0-29). Rates of induction of labor (63 of 131 [48.1%]) and cesarean delivery (53 of 131 [40.5%]) were significantly higher than national rates for multiparous women. Almost two-thirds of women (40 of 63 [63.5%]) cited previous history of stillbirth as the indication for induction. There was a significantly higher rate of preterm delivery (30 of 131 [22.9%]). Moreover, 1 in 4 babies (35 of 137 [25.5%]) required admission to the neonatal intensive care unit, more than twice the number expected (median gestation, 37 0/7 weeks; range, 25 4/7 to 39 2/7 weeks).

CONCLUSION

Pregnancy after stillbirth was associated with increased surveillance and intervention. The women in this study had higher rates of cesarean delivery, induction of labor, and preterm delivery than the general multiparous population. Decision-making for intervention was often based on previous history of stillbirth. Clinicians should be cognizant of additional supports required for this population and focus on evidence-based interventions that improve maternal well-being and perinatal outcomes in pregnancy after stillbirth.

Perinatal Grief and Related Factors After Termination of Pregnancy for Fetal Anomaly: One-Year Follow-up Study

Introduction:

Many people grieve in a resilient manner, often having a sense of equilibrium restored within six months. The most devastating type of loss is usually considered to be the death of the child. For such a loss, bereavement may take a period of distressing years with signs and symptoms that are related to grief. There have been different phases identified in the grieving process, and this process encompasses various difficulties with different levels of psychological effects. Women with perinatal losses can suffer long periods of grief. The purpose of this study was to monitor the grief in women who had undergone a termination of pregnancy due to fetal anomaly.

Methods:

Forty-six women who applied to the Gynaecology Clinic of Istanbul University Cerrahpaşa Faculty of Medicine and who decided to terminate their pregnancy due to fetal anomaly were included in the study. The Perinatal Grief Scale (PGS), the Impact of Event Scale-Revised (IES-R), Beck Anxiety Inventory (BAI), the Edinburgh Postnatal Depression Scale (EPDS), the Multidimensional Relationship Questionnaire (MRQ) and the Adult Attachment Scale (AAS) were administered to the participants six weeks after termination. Participants’ grief signs were re-evaluated with the PGS at the sixth and 12th months.

Results:

There was no relationship between severity of grief symptoms and socio-demographic and clinical characteristics of the patients. The perinatal grief symptoms can decrease gradually from termination of pregnancy to six months and can persist for a period of six months up to a year. There was positive correlation between the scores of PGS and BAI, IES-R hyper-arousal. The mean score of PGS changed significantly from sixth week to sixth month and from sixth week to 12th months. IES-R hyper-arousal and MRQ relational satisfaction were found to be the predictors for PGS total score at the first year.

Conclusion:

The diagnosis of fetal anomaly and especially the termination of pregnancy itself may be traumatic and disruptive. In women with perinatal loss, grief may become persistent after the first six months. It would be helpful to examine how the women resolve this experience. Especially the anxiety and the hyper-arousal signs following the termination should not be ignored. Perinatal grief is a unique bereavement experience; specific interventions should be performed for detecting and treating severe perinatal grief.

Induction of labour at 41 weeks of gestation versus expectant management and induction of labour at 42 weeks of gestation: a cost-effectiveness analysis

OBJECTIVE

To assess the cost-effectiveness of induction of labour (IOL) at 41 weeks of gestation compared with expectant management until 42 weeks of gestation.

DESIGN

A cost-effectiveness analysis alongside the Swedish Post-term Induction Study (SWEPIS), a multicentre, randomised controlled superiority trial.

SETTING

Fourteen Swedish hospitals during 2016-2018.

POPULATION

Women with an uncomplicated singleton pregnancy with a fetus in cephalic position were randomised at 41 weeks of gestation to IOL or to expectant management and induction at 42 weeks of gestation.

METHODS

Health benefits were measured in life years and quality-adjusted life years (QALYs) for mother and child. Total cost per birth was calculated, including healthcare costs from randomisation to discharge after delivery, for mother and child. Incremental cost-effectiveness ratios (ICERs) were calculated by dividing the difference in mean cost between the trial arms by the difference in life years and QALYs, respectively. Sampling uncertainty was evaluated using non-parametric bootstrapping.

MAIN OUTCOME MEASURES

The cost per gained life year and per gained QALY.

RESULTS

The differences in life years and QALYs gained were driven by the difference in perinatal mortality alone. The absolute risk reduction in mortality was 0.004 (from 6/1373 to 0/1373). Based on Swedish life tables, this gives a mean gain in discounted life years and QALYs of 0.14 and 0.12 per birth, respectively. The mean cost per birth was €4108 in the IOL group (n = 1373) and €4037 in the expectant management group (n = 1373), with a mean difference of €71 (95% CI -€232 to €379). The ICER for IOL compared with expectant management was €545 per life year gained and €623 per QALY gained. Confidence intervals were relatively wide and included the possibility that IOL had both lower costs and better health outcomes.

CONCLUSIONS

Induction of labour at 41 weeks of gestation results in a better health outcome and no significant difference in costs. IOL is cost-effective compared with expectant management until 42 weeks of gestation using standard threshold values for acceptable cost per life year/QALY.

TWEETABLE ABSTRACT

Induction of labour at 41 weeks of gestation is cost-effective compared with expectant management until 42 weeks of gestation.

The psychological effects of stillbirth on parents: A qualitative evidence synthesis of psychoanalytic literature

Objective: To review and synthesize existing psychoanalytic literature on the psychological impact of stillbirth on mothers and fathers. Method: This qualitative systematic review followed, as far as possible, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The Psychoanalytic Electronic Publishing Archive, the Single Case Archive, and PsycINFO (1999-2019) were searched to identify relevant articles published between 1999-2019 that report clinical material or theoretical considerations concerning the psychological effects of stillbirth on parents, as emerging during classical analytic or psychoanalytic therapy session/journey. A thematic synthesis was performed. Results: 46 articles were identified, providing data on the parents' experiences of grief and gender differences, the detrimental effects on the parental couple's relationship, the mother's identification with the dead baby, the importance for mothers to meet and care the stillborn baby, the mothers' drive for another pregnancy and the fear of further loss, the mothers' ambivalence toward subsequent pregnancy and child, the potential negative effects of unresolved bereavement on subsequent baby, and the replacement of a stillborn child. Conclusion: Our findings reveal there is some psychoanalytic literature providing insight into the psychological dynamics of parents after a stillbirth, with observations that could be used to improve psychological health care practices. One of the main therapeutic tasks was to facilitate parents to create a psychic space where they can bring to life, psychically, their lost and never- really-known stillborn baby, and to let him or her to be part of the on-going family narrative.

Single and mixed effects of metallic elements in maternal serum during pregnancy on risk for fetal neural tube defects: A Bayesian kernel regression approach

Studies of the association between prenatal exposure to metal elements and risk for neural tube defects (NTDs) have produced inconsistent results. Little research has examined the joint effects and interactions of multiple elements. This study examined 273 women with NTD-affected pregnancies and 477 controls. Cadmium, cobalt, chromium, copper, iron, mercury, manganese, molybdenum, lead, and zinc were quantified in maternal serum. Single and mixed effects of these elements on NTD risk were evaluated with Bayesian kernel machine regression, and the effects of individual elements were validated using logistic regression. As a result, NTD risk increased with the concentration of the mixture of the 10 elements. NTD risk rose as the levels of the five toxic elements increased, with effect sizes larger than the overall analyses, but they decreased, albeit non-significantly, as the levels of the five essential elements increased. Lead and manganese showed risk effects on NTDs, with odds ratios (ORs) of 1.94 (1.76-2.13) and 1.25 (1.14-1.38), respectively, with the remaining nine elements remaining at their median. Molybdenum showed a protective effect against NTDs with an OR 0.87 (0.90-0.94). The single-element results were validated using logistic regression. In conclusion, NTD risk increased with concentrations of the five toxic elements, with lead and manganese being the major contributors. Essential elements showed protective effects against NTD risk.

'This is time we'll never get back': a qualitative study of mothers' experiences of care associated with neonatal death

AIMS

To explore the perceptions and experience of women whose baby died in the neonatal period about their care in the perinatal period, on delivery suite, in the neonatal unit and afterwards, expressed in their own words.

DESIGN

Secondary analysis of the Listening to Parents study, using thematic analysis based on the open text responses from a postal survey of parents whose baby died in the neonatal period in England. Women were asked about care during the pregnancy, labour and birth, around the time the baby died and about neonatal care. Women whose pregnancy was terminated for fetal abnormality were excluded from this analysis.

RESULTS

Completed questionnaires were received from 249 mothers of whom most (78%) responded with open text. Overarching themes identified were 'the importance of proximity', 'recognition of role and identity as a parent' and 'the experience of care' and subthemes included 'hours and moments', 'barriers to contact', ' being able to parent, even for a short time', 'missed opportunities', 'being heard' and 'sensitive and responsive care'.

CONCLUSION

The findings identify what is most important for mothers in experiencing the life and death of a baby as a newborn. Physical contact with the baby was paramount, as was being treated as a mother and a parent and being able to function as such. The way in which healthcare staff behaved and how their babies were cared for was critical to how mothers felt supported and enabled at this time. If all women whose babies die in the neonatal period after birth are to receive the responsive care they need, greater understanding of the primary need for closeness and proximity, for active recognition of their parental role and staff awareness of the limited time window available is essential.

The brain oxytocin and corticotropin-releasing factor systems in grieving mothers: What we know and what we need to learn

The bond between a mother and her child is the strongest bond in nature. Consequently, the loss of a child is one of the most stressful and traumatic life events that causes Prolonged Grief Disorder in up to 94 % of bereaved parents. While both parents are affected, mothers are of higher risk to develop mental health complications; yet, very little research has been done to understand the impact of the loss of a child, stillbirth and pregnancy loss on key neurobiological systems. The emotional impact of losing a child, e.g., Prolonged Grief Disorder, is likely accompanied by dysregulations in neural systems important for mental health. Among those are the neuropeptides contributing to attachment and stress processing. In this review, we present evidence for the involvement of the brain oxytocin (OXT) and corticotropin-releasing factor (CRF) systems, which both play a role in maternal behavior and the stress response, in the neurobiology of grief in mothers from a behavioral and molecular point of view. We will draw conclusions from reviewing relevant animal and human studies. However, the paucity of research on the tragic end to an integral bond in a female's life calls for the need and responsibility to conduct further studies on mothers experiencing the loss of a child both in the clinic and in appropriate animal models.
