Experiences of antenatal care practices to reduce stillbirth: surveys of women and healthcare professionals pre-post implementation of the Safer Baby Bundle.

BACKGROUND: The Safer Baby Bundle (SBB) aimed to reduce stillbirth rates in Australia through improving pregnancy care across five elements; smoking cessation, fetal growth restriction (FGR), decreased fetal movements (DFM), side sleeping in late pregnancy and decision making around timing of birth. We assessed experiences of women and healthcare professionals (HCPs) with antenatal care practices around the five elements. METHODS: A pre-post study design using online surveys was employed to assess change in HCPs awareness, knowledge, and frequency of performing recommended practices (22 in total) and women's experiences of care received related to reducing their chance of stillbirth. Women who had received antenatal care and HCPs (midwives and doctors) at services participating in the SBB implementation program in two Australian states were invited to participate. Surveys were distributed over January to July 2020 (pre) and August to December 2022 (post). Comparison of pre-post responses was undertaken using Fisher's exact, Pearson's chi-squared or Wilcoxon rank-sum tests. RESULTS: 1,225 women (pre-1096/post-129) and 1,415 HCPs (pre-1148/post-267, ≥ 83% midwives) completed the surveys. The frequency of HCPs performing best practice 'all the time' significantly improved post-SBB implementation across all elements including providing advice to women on side sleeping (20.4-79.4%, p < 0.001) and benefits of smoking cessation (54.5-74.5%, p < 0.001), provision of DFM brochure (43.2-85.1%, p < 0.001), risk assessments for FGR (59.2-84.1%, p < 0.001) and stillbirth (44.5-73.2%, p < 0.001). Practices around smoking cessation in general showed less improvement e.g. using the 'Ask, Advise and Help' brief advice model at each visit (15.6-20.3%, p = 0.088). Post-implementation more women recalled conversations about stillbirth and risk reduction (32.2-50.4%, p < 0.001) and most HCPs reported including these conversations in their routine care (35.1-83.0%, p < 0.001). Most HCPs agreed that the SBB had become part of their routine practice (85.0%). CONCLUSIONS: Implementation of the SBB was associated with improvements in practice across all targeted elements of care in stillbirth prevention including conversations with women around stillbirth risk reduction. Further consideration is needed around strategies to increase uptake of practices that were more resistant to change such as smoking cessation support. TRIAL REGISTRATION: The Safer Baby Bundle Study was retrospectively registered on the Australian New Zealand Clinical Trials Registry database, ACTRN12619001777189, date assigned 16/12/2019.

The association between increased fetal movements in the third trimester and perinatal outcomes; a systematic review and meta-analysis.

BACKGROUND: Fetal movement monitoring is one of the strategies used to assess the fetus's health. Until now, most studies focused on the decreased fetal movement and neonatal outcome, although this systematic review and meta-analysis is designed to assess the association between increased fetal movements (IFM) with perinatal outcomes. METHOD: The electronic databases including PubMed, Scopus, Web of Science, and EMBASE were systematically searched for studies investigating the perinatal outcome of women with increased fetal movements from inception to July 2023. Following that, a random-effect meta-analysis model was used to obtain the combined diagnostic and predictive parameters including perinatal mortality (still birth and early neonatal mortality), operative delivery, Apgar score, neonatal resuscitation at birth and NICU Admission. RESULTS: After the initial screening, seven studies examining the association between increased third trimester fetal movement and various perinatal outcomes were included. Meta-analysis revealed a significant reduction in the risk of cesarean delivery among patients with IFM compared to controls, suggesting a potential protective effect during childbirth. However, no statistically significant difference was observed in birth weight, small or large for gestational age births, neonatal intensive care unit admission, maternal age, umbilical cord around the neck, gestational diabetes mellitus, and hypertension, indicating that IFM may not be a major predictor of adverse perinatal outcomes or maternal conditions. Notably, IFM was significantly associated with a higher likelihood of labor induction. CONCLUSION: The findings suggest that IFM may have a protective effect against cesarean delivery. Additionally, IFM does not appear to be significantly associated with maternal age, umbilical cord around the neck, gestational diabetes mellitus and hypertension. However, the observed significant association with labor induction warrants further investigation.

Pioneering a chick embryo model to explore the intrauterine etiology of developmental dysplasia of the hip in oligohydramnios conditions.

OBJECTIVE: To explore the impact of oligohydramnios on fetal movement and hip development, given its association with developmental dysplasia of the hip (DDH) but unclear mechanisms. METHODS: Chick embryos were divided into four groups based on the severity of oligohydramnios induced by amniotic fluid aspiration (control, 0.2 mL, 0.4 mL, 0.6 mL). Fetal movement was assessed by detection of movement and quantification of residual amniotic fluid volume. Hip joint development was assessed by gross anatomic analysis, micro-computed tomography (micro-CT) for cartilage assessment, and histologic observation at multiple time points. In addition, a subset of embryos from the 0.4 mL aspirated group underwent saline reinfusion and subsequent evaluation. RESULTS: Increasing volumes of aspirated amniotic fluid resulted in worsening of fetal movement restrictions (e.g., 0.4 mL aspirated and control group at E10: frequency difference -7.765 [95% CI: -9.125, -6.404]; amplitude difference -0.343 [95% CI: -0.588, -0.097]). The 0.4 mL aspirated group had significantly smaller hip measurements compared to controls, with reduced acetabular length (-0.418 [95% CI: -0.575, -0.261]) and width (-0.304 [95% CI: -0.491, -0.117]) at day E14.5. Histological analysis revealed a smaller femoral head (1.084 ± 0.264 cm) and shallower acetabulum (0.380 ± 0.106 cm) in the 0.4 mL group. Micro-CT showed cartilage matrix degeneration (13.6% [95% CI: 0.6%, 26.7%], P = 0.043 on E14.5). Saline reinfusion resulted in significant improvements in the femoral head to greater trochanter (0.578 [95% CI: 0.323, 0.833], P = 0.001). CONCLUSIONS: Oligohydramnios can cause DDH by restricting fetal movement and disrupting hip morphogenesis in a time-dependent manner. Timely reversal of oligohydramnios during the fetal period may prevent DDH.

Made to move: A review of measurement strategies to characterize heterogeneity in normal fetal movement.

Fetal movement is a crucial indicator of fetal well-being. Characteristics of fetal movement vary across gestation, posing challenges for researchers to determine the most suitable assessment of fetal movement for their study. We summarize the current measurement strategies used to assess fetal movement and conduct a comprehensive review of studies utilizing these methods. We critically evaluate various measurement approaches including subjective maternal perception, ultrasound, Doppler ultrasound, wearable technology, magnetocardiograms, and magnetic resonance imaging, highlighting their strengths and weaknesses. We discuss the challenges of accurately capturing fetal movement, which is influenced by factors such as differences in recording times, gestational ages, sample sizes, environmental conditions, subjective perceptions, and characterization across studies. We also highlight the clinical implications of heterogeneity in fetal movement assessment for monitoring fetal behavior, predicting adverse outcomes, and improving maternal attachment to the fetus. Lastly, we propose potential areas of future research to overcome the current gaps and challenges in measuring and characterizing abnormal fetal movement. Our review contributes to the growing body of literature on fetal movement assessment and provides insights into the methodological considerations and potential applications for research.

One size does not fit all: Perspectives from Swedish midwives on fetal movement counselling.

PROBLEM: Migration continues to play a role in determining health outcomes related to pregnancy and childbirth in Sweden. BACKGROUND: Migrant women have, compared to Swedish-born women, increased risks of adverse birth outcomes. Previous research suggests that migrant women seek care for decreased fetal movements less than Swedish-born women. Given these documented risks, understanding midwives' perspectives in this context is crucial to address maternal health inequities. AIM: To explore midwives' experiences conveying information about fetal movement to migrant women in antenatal healthcare settings. METHODS: Semi-structured, individual interviews with midwives (n=15) experienced in providing information about fetal movements to migrant women. The interviews were analysed using reflexive thematic analysis. FINDINGS: The midwives' efforts to compensate for the deficiencies within the antenatal healthcare organisation and to ensure that all women received access to information and care regarding fetal movements are described in four themes: (a) building a trusting relationship; (b) empowering women through guidance and support; (c) overcoming communication challenges; and d) navigating safety measures. DISCUSSION: Our findings suggest that the standard antenatal care programme does not support midwives to provide holistic and individualised care that aligns with midwifery care philosophy. CONCLUSION: To reduce health inequities for migrant women, this study highlights the need for more flexible guidelines within the standard antenatal care programme. These guidelines should prioritise the individual woman's needs over institutional protocols, acknowledge the midwife-woman relationship as the core of midwifery practice and support midwives to build a partnership with women through continuity of care.

Letter to the Editor: Does fetal movement shape the maternal brain?

Here, we debate that fetal behavior may contribute to the dynamic changes observed in the maternal brain during the perinatal period. We call for future research to explore this perspective to understand the complex maternal-fetal relationship and how fetal signals influence the preparation for parenthood.

Maternal perception of decreased fetal movements is independent of infant size.

OBJECTIVE: Fetal movements are often used as a surrogate for fetal wellbeing. Previous research suggests a link between maternal perception of decreased fetal movements (DFM) and small-for-gestational-age (SGA) infants. The aim of this study was to investigate the association between maternal presentation with DFM and birth-weight centile categories at a large Australian perinatal center. METHODS: This was a retrospective study of non-anomalous singleton infants born at ≥ 28 + 0 weeks' gestation between January 2016 and October 2020 at the Mater Mothers' Hospital in Brisbane, Australia. The primary outcome was the rate of DFM according to birth-weight centile category. Maternal demographic characteristics included age, body mass index, ethnicity, parity, medical conditions and previous stillbirth. The association between DFM and birth-weight centile was evaluated using adjusted multinomial regression models. Robust standard errors were used to account for clustering at the patient level. Wald tests and Akaike's and Bayesian information criteria were used to evaluate models. RESULTS: Over the 5-year study period, 45 042 women met the inclusion criteria. Of these, 6690 (14.9%) women presented with DFM. Of the DFM cohort, 80.9% (5411/6690) had only one presentation with DFM, and 19.1% (1279/6690) had two or more presentations. The overall stillbirth rate was similar in women with DFM (0.1% (8/6690)) and those without DFM (0.1% (50/38 352)). There was no association between DFM (either single or multiple) and infant birth-weight centile. CONCLUSIONS: This study suggests that presentation with DFM is not associated with infant size. Clinicians should consider additional risk factors and the overall clinical context when deciding appropriate management. DFM is not necessarily an indication for an immediate or urgent ultrasound scan to assess fetal size. © 2024 The Authors.

The effects of lockdown during the COVID-19 pandemic on fetal movement profiles.

PURPOSE: The current study investigated the direct impact of the COVID-19 lockdown on fetal movements, addressing a critical research gap. While previous research has predominantly examined the effects of lockdown on maternal health and postnatal outcomes, little attention has been paid to the direct consequences on fetal well-being as indicated by their movement profile. METHODS: We conducted analysis of movement profiles in 20 healthy fetuses during the COVID-19 pandemic lockdown (third national UK lockdown period between January and March 2021) and compared them with 20 healthy fetuses from pre-covid pregnancies, all at 32 weeks gestation. We controlled for maternal stress, depression, and anxiety. RESULTS: Pregnant mothers during pre-covid compared with those during the COVID-19 lockdown reported similar levels of stress (p = 0.47), depression (p = 0.15), and anxiety (p = 0.07). Their fetuses, however, differed in their movement profiles with mouth movement frequencies significantly higher during COVID-19 lockdown (COVID-19 lockdown: mean of 5.909) compared to pre-Covid pregnancies (mean of 3.308; p = 0.029). Furthermore, controlling for maternal anxiety a regression analysis indicated that frequency of fetal mouth movements (p = 0.017), upper face movements (p = 0.008), and touch movements (p = 0.031) were all significantly higher in fetuses observed during lockdown compared to fetuses before the Covid period. CONCLUSION: Fetuses show an effect of lockdown independent of maternal anxiety, stress, or depression. These findings contribute to our understanding of fetal development during extraordinary circumstances, raising questions about the potential effects of having to stay indoors during lockdowns.

Are reduced fetal movements "merely" a maternal perception or truly a reflection of umbilical cord complications? A clinical trial.

OBJECTIVE: To characterize obstetric outcomes and the association with umbilical cord (UC) complications among women complaining of reduced fetal movements (RFMs). METHODS: This retrospective cohort compared women with a perception of RFMs within 2 weeks prior to delivery with women who reported no changes in fetal movements in terms of maternal characteristics and neonatal outcomes. A primary outcome of UC complications at delivery was defined. Multivariable regression analysis was performed to identify independent associations with RFMs and UC complications. RESULTS: In all, 46 103 women were included, 2591 (5.6%) of whom reported RFMs and 43 512 (94.4%) in the control group. Compared with controls, the RFM group was more likely to be nulliparous (42.6% vs 32.2%, P < 0.001), smokers (6.4% vs 5.4%, P = 0.029), or obese (body mass index >30) (16.4% vs 11.6%, P < 0.001). They were also more likely to have an anterior placenta (56.2% vs 51.8%, P < 0.001) and poly/oligohydramnios (0.7% vs 0.4%, P = 0.015 and 3.6% vs 2.1%, P < 0.001, respectively). Induction of labor was more common in the RFM group (33.9% vs 19.7%, P < 0.001), as well as meconium (16.8% vs 15.0%, P = 0.026) and vacuum extractions (10.1% vs 8.0%, P < 0.001). Higher rates of stillbirth and the severe composite neonatal outcome were observed in the RFM group (1.5% vs 0.2%, P < 0.001 and 0.6% vs 0.3%, P = 0.010, respectively). The RFM group was characterized by higher rates of triple nuchal cord (P = 0.015), UC around body or neck (32.2% vs 29.6%, P = 0.010), and true knot (2.3% vs 1.4%, P = 0.002). Multivariable logistic regression found RFMs to be independently associated with triple nuchal cord and with a true cord knot. A sub-analysis including only cases of stillbirth (n = 127) revealed even higher rates of UC complications: 7% of all stillbirths presented with a true cord knot (20% true knots were found in stillbirths preceded by RFMs vs 6.1% in stillbirth cases without RFMs). Additionally, 33.8% of all stillbirths presented with nuchal cord (40% preceded by RFMs vs 33.3% without RFMs). CONCLUSIONS: RFMs are associated with increased risk of UC complications observed at delivery, as well as increased risk of stillbirth and neonatal adverse outcomes.

Midwives' and obstetricians' practice, perspectives and experiences in relation to altered fetal movement: A focused ethnographic study.

BACKGROUND: Reducing avoidable stillbirth is a global priority. The stillbirth rate in England compares unfavourably to that of some other high-income countries. Poorly-managed episodes of altered fetal movement have been highlighted as a key contributor to avoidable stillbirth, and strategies introduced in England in 2016 to reduce perinatal mortality included recommendations for the management of reduced fetal movement. Despite a downward trend in stillbirth rates across the UK, the effects of policies promoting awareness of fetal movement remain uncertain. OBJECTIVE: To provide in-depth knowledge of how practice and clinical guidance relating to altered fetal movement are perceived, enacted and experienced by midwives and obstetricians, and explore the relationship between recommended fetal movement care and actual fetal movement care. DESIGN: A focused ethnographic approach comprising over 180 h of observation, 15 interviews, and document analysis was used to explore practice at two contrasting UK maternity units. SETTINGS: Antenatal services at two UK maternity units, one in the Midlands and one in the North of England. PARTICIPANTS: Thirty-six midwives, obstetricians and sonographers and 40 pregnant women participated in the study across 52 observed care episodes and relevant unit activity. Twelve midwives and three obstetricians additionally participated in formal semi-structured interviews. METHODS: Fieldnotes, interview transcripts, policy documents, maternity notes and clinical guidelines were analysed using a modified constant comparison method to identify important themes. RESULTS: fetal movement practice was mostly consistent and in line with guideline recommendations. Notwithstanding, most midwives and obstetricians had concerns about this area of care, including challenges in diagnosis, conflicting evidence about activity, heightened maternal anxiety, and high rates of monitoring and intervention in otherwise low-risk pregnancies. To address these issues, midwives spent considerable time reassuring women through information and regular monitoring, and coaching them to perceive fetal movement more accurately. CONCLUSIONS: Practice relating to altered fetal movement might be more uniform than in the past. However, a heightened focus on fetal movement is associated by some midwives and obstetricians with potential harms, including increased anxiety in pregnancy, and high rates of monitoring and intervention in pregnancies where there are no 'objective concerns'. Challenges in diagnosing a significant change in fetal movement with accuracy might mean that interventions and resources are not being directed towards those pregnancies most at risk. More research is needed to determine how healthcare professionals can engage in conversations about fetal movement and stillbirth to support safe outcomes and positive experiences in pregnancy and birth. REGISTRATION: Not registered. TWEETABLE ABSTRACT: Midwives and obstetricians take #reducedfetalmovement seriously but worry this 'unreliable' symptom increases anxiety, monitoring and intervention in many 'low risk' pregnancies.

Decreased fetal movements: Report from the International Stillbirth Alliance conference workshop.

Maternal reports of decreased fetal movement (DFM) are a common reason to present to maternity care and are associated with stillbirth and other adverse outcomes. Promoting awareness of fetal movements and prompt assessment of DFM has been recommended to reduce stillbirths. However, evidence to guide clinical management of such presentations is limited. Educational approaches to increasing awareness of fetal movements in pregnant women and maternity care providers with the aim of reducing stillbirths have recently been evaluated in a several large clinical trials internationally. The International Stillbirth Alliance Virtual Conference in Sydney 2021 provided an opportunity for international experts in fetal movements to share reports on the findings of fetal movement awareness trials, consider evidence for biological mechanisms linking DFM and fetal death, appraise approaches to clinical assessment of DFM, and highlight research priorities in this area. Following this workshop summaries of the sessions prepared by the authors provide an overview of understandings of fetal movements in maternity care at the current time and highlights future directions in fetal movement research.

Effect of social support on fetal movement self-monitoring behavior in Chinese women: a moderated mediation model of health beliefs.

OBJECTIVE: Strengthening the management of women's self-monitoring during pregnancy is important to reduce fetal death in utero and improve maternal and infant outcomes. However, due to the lack of awareness among pregnant women about the importance of self-monitoring fetal movement, resulting in low behavioral compliance, adverse pregnancy outcomes remain common in China. This study aimed to investigate the relationship between social support and health beliefs and the self-monitoring behavior of fetal movement. In addition, we examined the moderating and mediating effects of health beliefs on fetal movement self-monitoring. METHODS: This cross-sectional study was conducted on 200 postpartum mothers in a tertiary hospital in China. The mothers were asked to complete a socio-demographic questionnaire, the fetal movement self-monitoring behavior questionnaire, the fetal movement self-monitoring health beliefs questionnaire, and the social support rating scale. Data from the questionnaires were analyzed and compared using SPSS 24.0 and PROCESS 3.2. RESULTS: The results of this study showed that the total scores of social supports, health beliefs, fetal movement self-monitoring were 42.98 ± 11.65, 78.605 ± 13.73, and 11.635 ± 2.86, respectively. The study found that when social support and health beliefs were included in the regression equation, both social support and health beliefs showed a positive correlation with fetal movement self-monitoring. Health beliefs partially mediated the effect of social support on fetal movement self-monitoring, accounting for 37.5% of the total effect. CONCLUSION: Social support and health beliefs play a crucial role in influencing the self-monitoring behavior of fetal movements. Therefore, strengthening social support and health beliefs during pregnancy has the potential to improve compliance with fetal movement self-monitoring behaviors for pregnant women.

Continuity and change in neural plasticity through embryonic morphogenesis, fetal activity-dependent synaptogenesis, and infant memory consolidation.

There is an apparent continuity in human neural development that can be traced to venerable themes of vertebrate morphogenesis that have shaped the evolution of the reptilian telencephalon (including both primitive three-layered cortex and basal ganglia) and then the subsequent evolution of the mammalian six-layered neocortex. In this theoretical analysis, we propose that an evolutionary-developmental analysis of these general morphogenetic themes can help to explain the embryonic development of the dual divisions of the limbic system that control the dorsal and ventral networks of the human neocortex. These include the archicortical (dorsal limbic) Papez circuits regulated by the hippocampus that organize spatial, contextual memory, as well as the paleocortical (ventral limbic) circuits that organize object memory. We review evidence that these dorsal and ventral limbic divisions are controlled by the differential actions of brainstem lemnothalamic and midbrain collothalamic arousal control systems, respectively, thereby traversing the vertebrate subcortical neuraxis. These dual control systems are first seen shaping the phyletic morphogenesis of the archicortical and paleocortical foundations of the forebrain in embryogenesis. They then provide dual modes of activity-dependent synaptic organization in the active (lemnothalamic) and quiet (collothalamic) stages of fetal sleep. Finally, these regulatory systems mature to form the major systems of memory consolidation of postnatal development, including the rapid eye movement (lemnothalamic) consolidation of implicit memory and social attachment in the first year, and then-in a subsequent stage-the non-REM (collothalamic) consolidation of explicit memory that is integral to the autonomy and individuation of the second year of life.

Small estimated placental volume (EPV) in the setting of decreased fetal movement.

Although 60.5 % of clinically unexplained stillbirths can be attributed to placental insufficiency and/or fetal growth restriction, clinicians rarely calculate estimated placental volume (EPV). We present a scenario in which EPV was used to inform patient care of a 28-year-old with decreased fetal movement at 32 weeks and 1 day gestation. Although estimated fetal weight (EFW), amniotic fluid index (AFI), and nonstress test (NST) were normal, EPV was low (<0.1st percentile), which prompted more frequent patient follow-up. Oligohydramnios was detected at 38 weeks and 1 day, and labor was induced. An infant with birthweight in the 12th percentile for gestational age was born. We learned that EPV can precede intrauterine growth restriction (IUGR), oligohydramnios, and low birthweight.
