METHODS: This was a prospective nationwide study of pregnancies with isolated fetal gastroschisis that underwent serial longitudinal ultrasound examination at regular specified intervals between 20 and 37 weeks' gestation. The primary outcome was simple or complex (i.e. involving bowel atresia, volvulus, perforation or necrosis) gastroschisis at birth. Fetal biometry (abdominal circumference and estimated fetal weight), the occurrence of polyhydramnios, intra- and extra-abdominal bowel diameters and the pulsatility index (PI) of the superior mesenteric artery (SMA) were assessed. Linear mixed modeling was used to compare the individual trajectories of cases with simple and those with complex gastroschisis, and logistic regression analysis was used to estimate the strength of association between the ultrasound parameters and outcome. RESULTS: Of 104 pregnancies with isolated fetal gastroschisis included, four ended in intrauterine death. Eighty-one (81%) liveborn infants with simple and 19 (19%) with complex gastroschisis were included in the analysis. We found no relationship between fetal biometric variables and complex gastroschisis. The SMA-PI was significantly lower in fetuses with gastroschisis than in healthy controls, but did not differentiate between simple and complex gastroschisis. Both intra- and extra-abdominal bowel diameters were larger in cases with complex, compared to those with simple, gastroschisis (P < 0.001 and P < 0.005, respectively). The presence of intra-abdominal bowel diameter >/= 97.7(th) percentile on at least three occasions, not necessarily on successive examinations, was associated with an increased risk of the fetus having complex gastroschisis (relative risk, 1.56 (95% CI, 1.02-2.10); P = 0.006; positive predictive value, 50.0%; negative predictive value, 81.4%). CONCLUSIONS: This large prospective longitudinal study found that intra-abdominal bowel dilatation when present repeatedly during fetal development can differentiate between simple and complex gastroschisis; however, the positive predictive value is low, and therefore the clinical usefulness of this marker is limited.

Objective Postpartum haemorrhage (PPH) complicates approximately 5% of births worldwide and is a leading direct cause of maternal death. Rates of PPH are increasing in many developed countries, particularly PPH related to uterine atony. There is a lack of published up-to-date information about healthcare resource use associated with management of PPH following vaginal birth. The objective of this study was to describe healthcare resource use for the management of minor PPH (blood loss 500-1,000ml) and major PPH (blood loss >1,000ml) compared to uncomplicated birth (no PPH) following hospital vaginal birth in France, Italy, the Netherlands, and the UK. Study design In-depth interviews with two midwives from each participating country were conducted to establish differences in resource use for the management of minor PPH, major PPH, and uncomplicated birth. A web-survey was then developed and one obstetrician per participating country reviewed the survey. In total, 100 midwives (25 per country) completed the survey. Results were discussed at a multi-professional consensus meeting of midwives and obstetricians/gynaecologists (n=6). Results and Conclusions Midwives participating in the survey estimated that 80% of women receive Active Management of the Third Stage of Labour (AMTSL) and 93% of participants specified that uterotonics would routinely be used during AMTSL. Most participants (84%) reported that blood loss is routinely measured in their hospital, using a combination of methods. PPH is associated with increased healthcare resource use, including administration of additional uterotonics and use of additional medical interventions, such as urinary catheter, intravenous fluids, and possible requirement for surgery. The number of nurses, obstetricians/gynaecologists, and anaesthetists involved in the management of PPH increases with the occurrence and severity of PPH, as well as the proportion of healthcare personnel providing continuous care. Women may spend an additional 24 hours in hospital following major PPH compared to uncomplicated birth. The results of this study highlight the burden of PPH management on healthcare resources. To reduce costs associated with PPH, prevention is the most effective strategy and can be enhanced with the use of an effective uterotonic as part of the active management of the third stage of labour.

Background Indicators to evaluate progress towards timely access to safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed to capture access to surgery, surgical workforce, surgical volume, perioperative mortality rate, and catastrophic and impoverishing financial consequences of surgery. Despite being rapidly taken up by practitioners, data points from which to derive the indicators were not defined, limiting comparability across time or settings. We convened global experts to evaluate and explicitly define—for the first time—the indicators to improve comparability and support achievement of 2030 goals to improve access to safe affordable surgical and anaesthesia care globally. Methods and findings The Utstein process for developing and reporting guidelines through a consensus building process was followed. In-person discussions at a 2-day meeting were followed by an iterative process conducted by email and virtual group meetings until consensus was reached. The meeting was held between June 16 to 18, 2019; discussions continued until August 2020. Participants consisted of experts in surgery, anaesthesia, and obstetric care, data science, and health indicators from high-, middle-, and low-income countries. Considering each of the 6 indicators in turn, we refined overarching descriptions and agreed upon data points needed for construction of each indicator at current time (basic data points), and as each evolves over 2 to 5 (intermediate) and >5 year (full) time frames. We removed one of the original 6 indicators (one of 2 financial risk protection indicators was eliminated) and refined descriptions and defined data points required to construct the 5 remaining indicators: geospatial access, workforce, surgical volume, perioperative mortality, and catastrophic expenditure. A strength of the process was the number of people from global institutes and multilateral agencies involved in the collection and reporting of global health metrics; a limitation was the limited number of participants from low- or middle-income countries—who only made up 21% of the total attendees. Conclusions To track global progress towards timely access to quality SAO care, these indicators—at the basic level—should be implemented universally as soon as possible. Intermediate and full indicator sets should be achieved by all countries over time. Meanwhile, these evolutions can assist in the short term in developing national surgical plans and collecting more detailed data for research studies., Justine Davies and colleagues discuss the development of updated indicators to support global achievement of access to safe surgical, anaesthetic, and obstetric care.

Objective To determine whether complex gastroschisis (ie, intestinal atresia, perforation, necrosis, or volvulus) can prenatally be distinguished from simple gastroschisis by fetal stomach volume and stomach‐bladder distance, using three‐dimensional (3D) ultrasound. Methods This multicenter prospective cohort study was conducted in the Netherlands between 2010 and 2015. Of seven university medical centers, we included the four centers that performed longitudinal 3D ultrasound measurements at a regular basis. We calculated stomach volumes (n = 223) using Sonography‐based Automated Volume Count. The shortest stomach‐bladder distance (n = 241) was determined using multiplanar visualization of the volume datasets. We used linear mixed modelling to evaluate the effect of gestational age and type of gastroschisis (simple or complex) on fetal stomach volume and stomach‐bladder distance. Results We included 79 affected fetuses. Sixty‐six (84%) had been assessed with 3D ultrasound at least once; 64 of these 66 were liveborn, nine (14%) had complex gastroschisis. With advancing gestational age, stomach volume significantly increased, and stomach‐bladder distance decreased (both P, What's already known about this topic? Infants with complex gastroschisis have a higher risk of morbidity than those with simple gastroschisis.Many attempts have been made to prenatally predict complex gastroschisis, using two‐dimensional ultrasound parameters. What does this study add? This longitudinal prospective multicenter study is the first to evaluate the possible benefit of the use of three‐dimensional ultrasound in fetuses with gastroschisis.Fetal stomach volume and stomach‐bladder distance, measured during pregnancy using three‐dimensional ultrasound, cannot predict complex gastroschisis.

The continuing rise in the global prevalence of diabetes and overweight or obesity has become a major burden for global health, as the pandemic is affecting both high and low-middle income countries (LMIC). At the same time, a similar pattern has been observed for all forms of hyperglycemia in pregnancy (HIP), diabetes during pregnancy and gestational diabetes. The offspring of mothers with HIP and/or overweight-obesity is receiving increasing attention as advances in early detection and treatment of HIP did not completely prevent macrosomia and its associated short-term perinatal disorders, whilst long term consequences are observed in the mother and in offspring as it reaches adulthood. This review discusses the current developments in the consequences of HIP in the offspring, with a particular focus on its long-term health at adulthood, and on intergenerational and transgenerational effects. HIP is emerging as one of the factors that can contribute, during the window of sensitivity to environmental cues constituted by the preconception, pregnancy, and early childhood, and as an amplifying factor linked to reproduction, to the current global epidemic of diabetes and non-communicable diseases (NCDs).

Publication of the Intergrowth-21st and WHO growth charts raises the question of which growth data prenatal providers should use in clinical practice. Is it better to use a universal chart applied globally, or metrics based on local or regional growth patterns? And what about customized charts versus local charts? FIGO has reviewed the different growth charts and studies assessing their reproducibility and predictive values for small- and large-for-gestational age newborns and, where available, adverse fetal outcomes. It concludes that local or regional charts are likely to be best for identifying the 10th percentile of newborns at highest risk. However, international standards for growth may also be used when coupled with locally appropriate thresholds for risk interpretation.

Hypertensive disorders are a leading cause of maternal morbidity and mortality worldwide. Despite advances in prevention and clinical management, women in low-resource countries continue to bear the burden of the sequelae of severe pre-eclampsia-eclampsia. Sustainable strategies to improve the care of women with hypertensive disease, to identify those at risk for hypertensive disease, and to reduce the risk of eclampsia will require partnerships between clinicians and health policy makers. Resources are needed to scale up healthcare access and infrastructure, establish evidence-based protocols for care, and ensure an adequate supply of equipment and drugs. Additionally, efforts for a sustained workforce of perinatal clinicians and staff trained in the assessment and management of hypertensive disease are needed. Effective postpartum care and monitoring are essential to prevent morbidity and mortality due to cardiovascular disease. Culturally appropriate strategies are needed to educate women and their families on the symptoms of pre-eclampsia to address delays in seeking care during pregnancy and postpartum. With targeted, sustained efforts and resources, eclampsia and its associated co-morbidities can be preventable.

The introduction of anti‐Rh(D) immunoglobulin more than 50 years ago has resulted in only a 50% decrease in Rhesus disease globally owing to a low uptake of this prophylactic approach. The International Federation of Gynecology and Obstetrics, International Confederation of Midwives, and Worldwide Initiative for Rhesus Disease Eradication have reviewed current evidence regarding the utility of anti‐Rh(D) immunoglobulin. Taking into account the effectiveness anti‐Rh(D), the new guidelines propose adjusting the dose for different indications and prioritizing its administration by indication., These FIGO/ICM guidelines review the evidence regarding the usefulness of anti‐Rh(D) immunoglobulin, prioritizing its administration by indication.

Pregnant women and their fetuses are among the vulnerable populations that can be severely affected by communicable diseases. As such, some vaccines such as the influenza and the Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccines are strongly recommended in each pregnancy, with generally safe profiles. Other vaccines can be offered based on risk factors, and only when the benefits of receiving them outweigh the risks. Development of vaccines against group B streptococcus infection and respiratory syncytial virus infection are of great importance. In this paper, the recommendations for administration of each vaccine during pregnancy are discussed. The FIGO Committee for Safe Motherhood and Newborn Health Committee endorses the recommendations to vaccinate all pregnant women against influenza during the influenza season at any time during the pregnancy and against Tdap preferably between the 27th and 36th weeks of pregnancy in each pregnancy.

Background The increased use of antidepressant treatment during pregnancy occurred without firm evidence on safety/efficacy. The present study investigated the correlation among S100B and paroxetine blood levels with the occurrence of short-term post-natal neurological abnormalities. Methods We conducted a cross-sectional study in 50 pregnant women using paroxetine because of depression and in 150 controls. Standard laboratory parameters and S100B were measured at seven monitoring time-points (maternal blood: T1, 16–20 wks; T2, 27–30 wks; T3, 35–40 wks; T4, at delivery; amniotic fluid, T5; venous and arterial cord blood, T6-T7). Paroxetine levels were measured at T1-T6. Neurological outcome was set at 7th day from birth. Results Higher S100B concentrations at T1-T7 were found in the paroxetine-treated group. S100B correlated with paroxetine blood levels. The paroxetine/S100B ratio cut-off of 1.31 at T2 achieved sensitivity 100%, specificity 96.5% and positive/negative predictive values 87.5–100, respectively, as a single marker to predict adverse neonatal neurological outcome. Conclusions The present study offers additional support to the usefulness of longitudinal S100B and drug level monitoring in depressed pregnant women and in the early detection of cases at risk for short-term neurological abnormalities. Results open the way at further investigations correlating antidepressant drugs and neurobiomarkers in the maternal bloodstream.

In the mid-20th century, Hemolytic Disease of the Fetus and Newborn, caused by maternal alloimmunization to the Rh(D) blood group antigen expressed by fetal red blood cells (i.e., “Rh disease”), was a major cause of fetal and neonatal morbidity and mortality. However, with the regulatory approval, in 1968, of IgG anti-Rh(D) immunoprophylaxis to prevent maternal sensitization, the prospect of eradicating Rh disease was at hand. Indeed, the combination of antenatal and post-partum immunoprophylaxis is ~99% effective at preventing maternal sensitization to Rh(D). To investigate global compliance with this therapeutic intervention, we used an epidemiological approach to estimate the current annual number of pregnancies worldwide involving an Rh(D)-negative mother and an Rh(D)-positive fetus. The annual number of doses of anti-Rh(D) IgG required for successful immunoprophylaxis for these cases was then calculated and compared with an estimate of the annual number of doses of anti-Rh(D) produced and provided worldwide. Our results suggest that ~50% of the women around the world who require this type of immunoprophylaxis do not receive it, presumably due to a lack of awareness, availability, and/or affordability, thereby putting hundreds of thousands of fetuses and neonates at risk for Rh disease each year. The global failure to provide this generally acknowledged standard-of-care to prevent Rh disease, even 50 years after its availability, contributes to an enormous, continuing burden of fetal and neonatal disease and provides a critically important challenge to the international health care system.

Summary A caesarean section (CS) can be a life-saving intervention when medically indicated, but this procedure can also lead to short-term and long-term health effects for women and children. Given the increasing use of CS, particularly without medical indication, an increased understanding of its health effects on women and children has become crucial, which we discuss in this Series paper. The prevalence of maternal mortality and maternal morbidity is higher after CS than after vaginal birth. CS is associated with an increased risk of uterine rupture, abnormal placentation, ectopic pregnancy, stillbirth, and preterm birth, and these risks increase in a dose–response manner. There is emerging evidence that babies born by CS have different hormonal, physical, bacterial, and medical exposures, and that these exposures can subtly alter neonatal physiology. Short-term risks of CS include altered immune development, an increased likelihood of allergy, atopy, and asthma, and reduced intestinal gut microbiome diversity. The persistence of these risks into later life is less well investigated, although an association between CS use and greater incidence of late childhood obesity and asthma are frequently reported. There are few studies that focus on the effects of CS on cognitive and educational outcomes. Understanding potential mechanisms that link CS with childhood outcomes, such as the role of the developing neonatal microbiome, has potential to inform novel strategies and research for optimising CS use and promote optimal physiological processes and development.

As management of respiratory distress syndrome (RDS) advances, clinicians must continually revise their current practice. We report the fourth update of "European Guidelines for the Management of RDS" by a European panel of experienced neonatologists and an expert perinatal obstetrician based on available literature up to the end of 2018. Optimising outcome for babies with RDS includes prediction of risk of preterm delivery, need for appropriate maternal transfer to a perinatal centre and timely use of antenatal steroids. Delivery room management has become more evidence-based, and protocols for lung protection including initiation of CPAP and titration of oxygen should be implemented immediately after birth. Surfactant replacement therapy is a crucial part of management of RDS, and newer protocols for its use recommend early administration and avoidance of mechanical ventilation. Methods of maintaining babies on non-invasive respiratory support have been further developed and may cause less distress and reduce chronic lung disease. As technology for delivering mechanical ventilation improves, the risk of causing lung injury should decrease, although minimising time spent on mechanical ventilation using caffeine and, if necessary, postnatal steroids are also important considerations. Protocols for optimising general care of infants with RDS are also essential with good temperature control, careful fluid and nutritional management, maintenance of perfusion and judicious use of antibiotics all being important determinants of best outcome.

ObjectiveTo investigate possible associations between remifentanil and the appearance of sinusoidal heart rate patterns in fetuses, and neonatal outcomes. MethodsThe present retrospective cohort study included data from patients at over 37weeks of singleton or multiple pregnancies attending Zuyderland Medical Center, Sittard, the Netherlands, in labor between June 1, and August 31, 2015. Patient data were stratified by whether remifentanil was administered during delivery (remifentanil group) or not (control group), and fetal heart rate tracings were reviewed to identify sinusoidal heart rate patterns. The neonatal outcomes compared were 5-minute Apgar scores and umbilical artery pH. ResultsThere were 119 patients included in the study; 60 in the remifentanil group and 59 in the control group. Tracings from 20 (33%) patients in the remifentanil group exhibited a sinusoidal heart rate pattern after remifentanil administration, compared with 5 (8%) patients in the control group (P=0.001). The median time before the onset of sinusoidal patterns after remifentanil administration was 12minutes. No adverse neonatal outcomes were recorded in either group. ConclusionRemifentanil use during labor was associated with the occurrence of sinusoidal heart rate patterns in the fetus; this was not associated with adverse neonatal outcomes. Remifentanil use during labor was associated with sinusoidal heart rate patterns in fetuses but not adverse neonatal outcomes.

OBJECTIVES: In the recent TRUFFLE study it appeared that, in pregnancies complicated by fetal growth restriction (FGR) between 26 and 32 weeks, monitoring of the ductus venosus (DV) combined with computerised cardiotocography (cCTG) as a trigger for delivery, increased the chance of infant survival without neurological impairment. However, concerns in interpretation were raised as DV monitoring appeared associated with a non-significant increase in fetal death, and part of the infants were delivered after 32 weeks, after which the study protocol was no longer applied. This secondary sensitivity analysis focuses on women who delivered before 32 completed weeks, and analyses fetal death cases in detail. METHODS: We analysed the monitoring data of 317 women who delivered before 32 weeks, excluding women with absent infant outcome data or inevitable perinatal death. The association of the last monitoring data before delivery and infant outcome was assessed by multivariable analysis. RESULTS: The primary outcome (two year survival without neurological impairment) occurred more often in the two DV groups (both 83%) than in the CTG-STV group (77%), however the difference was not statistically significant (p = 0.21). Nevertheless, in surviving infants 93% was free of neurological impairment in the DV groups versus 85% in the CTG-STV group (p = 0.049). All fetal deaths (n = 7) occurred in women allocated to DV monitoring, which explains this difference. Assessment of the monitoring parameters that were obtained shortly before fetal death in these 7 cases showed an abnormal CTG in only one. Multivariable regression analysis of factors at study entry demonstrated that higher gestational age, larger estimated fetal weight 50th percentile ratio and lower U/C ratio were significantly associated with the (normal) primary outcome. Allocation to the DV groups had a smaller effect, but remained in the model (p

There remains uncertainty about the optimal route of delivering carefully selected breech babies at term. This review argues strongly that vaginal mode of delivery should be considered in selected cases rather than offering an elective caesarean section for every patient.

Background: Although the evidence regarding the benefit of using ST waveform analysis of the fetal electrocardiogram is conflicting, ST waveform analysis is considered as adjunct to identify fetuses at risk for asphyxia in our center. Most randomized controlled trials and meta-analyses have not shown a significant decrease in umbilical metabolic acidosis, while some observational studies have shown a gradual decrease of this outcome over a longer period of time. Observational studies can give more insight into the effect of implementation of the ST technology in daily clinical practice. Objective: To evaluate the change in frequency of perinatal intervention and adverse neonatal outcome after the implementation of ST waveform analysis of the fetal electrocardiogram from 2000 to 2013. Study Design: This retrospective longitudinal study was conducted in a tertiary referral center. A total of 19,664 medium- and high-risk singleton pregnancies with fetuses in cephalic presentation, a gestational age of ≥36 weeks, and the intention to deliver vaginally were included. ST waveform analysis of the fetal electrocardiogram was implemented in the year 2000 and by 2010 all deliveries were monitored using this technology. Data were collected on the following perinatal outcomes: fetal blood sampling, mode of delivery, umbilical cord blood gases, Apgar scores, neonatal encephalopathy, and perinatal death. Longitudinal trend analysis was used to detect changes over time in all deliveries monitored by cardiotocography either alone or in adjunct to ST waveform analysis of the fetal electrocardiogram. Logistic regression was used to correct for possible confounders. Results: The umbilical artery metabolic acidosis rate declined from 2.5% (average rate of 2000 + 2001 + 2002) to 0.4% (average of 2011 + 2012 + 2013) (P < .001), which represents an 84% decrease. This decrease largely occurred between 2006 and 2008, during the Dutch randomized trial on fetal electrocardiogram ST waveform analysis. At this time, approximately 20% of deliveries were monitored using this method. Furthermore, there were significant reductions in fetal blood sampling rate (P < .001). Overall cesarean and vaginal instrumental deliveries decreased significantly (P < .001), but not for fetal distress. There were no changes in the Apgar scores. The incidence of neonatal encephalopathy was significantly lower in the second part of the study (odds ratio 0.39, 95% confidence interval 0.17–0.89). Conclusion: There was an 84% decrease in the incidence of umbilical artery metabolic acidosis in all deliveries between 2000 and 2013. The neonatal encephalopathy rate, fetal blood sampling rate, and the total number of cesarean and vaginal instrumental deliveries also decreased.

Many studies have reported on the association of reduced fetal movements and stillbirth, but little is known about excessive fetal movements and adverse pregnancy outcome. First described in 1977, sudden excessive fetal movement was noted to reflect acute fetal distress and subsequent fetal demise. Subsequently, little was reported regarding this phenomenon until 2012. However, emerging data suggest that 10-30% of the women that subsequently suffer a stillbirth describe a single episode of excessive fetal movement prior to fetal demise. These episodes are poorly understood but may reflect fetal seizure activity secondary to fetal asphyxia, cord entanglement or an adverse intrauterine environment. At present, the challenge in managing women with excessive fetal movements is a timely assessment of the fetus to identify those women at risk of adverse fetal outcomes who may benefit from intervention.

Advances in the management of respiratory distress syndrome (RDS) ensure that clinicians must continue to revise current practice. We report the third update of the European Guidelines for the Management of RDS by a European panel of expert neonatologists including input from an expert perinatal obstetrician based on available literature up to the beginning of 2016. Optimizing the outcome for babies with RDS includes consideration of when to use antenatal steroids, and good obstetric practice includes methods of predicting the risk of preterm delivery and also consideration of whether transfer to a perinatal centre is necessary and safe. Methods for optimal delivery room management have become more evidence based, and protocols for lung protection, including initiation of continuous positive airway pressure and titration of oxygen, should be implemented from soon after birth. Surfactant replacement therapy is a crucial part of the management of RDS, and newer protocols for surfactant administration are aimed at avoiding exposure to mechanical ventilation, and there is more evidence of differences among various surfactants in clinical use. Newer methods of maintaining babies on non-invasive respiratory support have been developed and offer potential for greater comfort and less chronic lung disease. As technology for delivering mechanical ventilation improves, the risk of causing lung injury should decrease although minimizing the time spent on mechanical ventilation using caffeine and if necessary postnatal steroids are also important considerations. Protocols for optimizing the general care of infants with RDS are also essential with good temperature control, careful fluid and nutritional management, maintenance of perfusion and judicious use of antibiotics all being important determinants of best outcome.

PURPOSE: Third trimester maternal perception of fetal movements is often used to assess fetal well-being. However, its true clinical value is unknown, primarily because of the variability in subjective quantification. The actograph, a technology available on most cardiotocograph machines, quantifies movements, but has never previously been investigated in relation to fetal health and existing monitoring devices. The objective of this study was to quantify actograph output in healthy third trimester pregnancies and investigate this in relation to other methods of assessing fetal well-being. METHODS: Forty-two women between 24 and 34 weeks of gestation underwent ultrasound scan followed by a computerized cardiotocograph (CTG). Post capture analysis of the actograph recording was performed and expressed as a percentage of activity over time. The actograph output results were analyzed in relation to Doppler, ultrasound and CTG findings expressed as z-score normalized for gestation. RESULTS: There was a significant association between actograph output recording and estimated fetal weight Z-score (R = 0.546, p ≤ .005). This activity was not related to estimated fetal weight. Increased actograph activity was negatively correlated with umbilical artery pulsatility index Z-score (R = -0.306, p = .049) and middle cerebral artery pulsatility index Z-score (R = -0.390, p = .011). CONCLUSION: Fetal movements assessed by the actograph are associated both with fetal size in relation to gestation and fetoplacental Doppler parameters. It is not the case that larger babies move more, however, as the relationship with actograph output related only to estimated fetal weight z-score. These findings suggest a plausible link between the frequency of fetal movements and established markers of fetal health. RATIONALE The objective of this study was to quantify actograph output in healthy third trimester pregnancies and investigate this in relation to other methods of assessing fetal well-being. This is a widely available method of assessing fetal movements objectively, which has been shown to be an important marker of fetal health. This research is novel in the fact that actograph has never been truly investigated in relation to fetal well-being, despite being available on most cardiotocograph (CTG) machines. Our results show that fetal movements assessed by the actograph are associated both with fetal size in relation to gestation and fetoplacental Doppler parameters. If this proves to be true, smaller babies that move less maybe at particular perinatal risk.

Hyperglycemia in pregnancy (HIP) is recognized as a major underlying cause of pregnancy complications and a contributing cause to health risks throughout the subsequent life of both mothers and babies, with amplification of the global epidemic of non-communicable diseases. Although some aspects of these associations are well described, detailed understanding of basic pathophysiologic mechanisms is lacking. Improved fundamental scientific knowledge must be developed to allow logical strategies for prevention and treatment. During pregnancy, much work is required to replace current empirical approaches to diagnosis and treatment of HIP with evidence based protocols, pragmatically adapted to differing health care and health economic contexts. Further, a life cycle approach to HIP, the risk of immediate pregnancy complications and later health risks to mother and baby must be developed and implemented across a wide range of health care environments. This document aims to outline key focus areas for further basic, epidemiologic, clinical and implementation research in this important area.

Background: Early-onset fetal growth restriction represents a particular dilemma in clinical management balancing the risk of iatrogenic prematurity with waiting for the fetus to gain more maturity, while being exposed to the risk of intrauterine death or the sequelae of acidosis. Objective: The Trial of Umbilical and Fetal Flow in Europe was a European, multicenter, randomized trial aimed to determine according to which criteria delivery should be triggered in early fetal growth restriction. We present the key findings of the primary and secondary analyses. Study Design: Women with fetal abdominal circumference 95th percentile between 26-32 weeks were randomized to 1 of 3 monitoring and delivery protocols. These were: fetal heart rate variability based on computerized cardiotocography; and early or late ductus venosus Doppler changes. A safety net based on fetal heart rate abnormalities or umbilical Doppler changes mandated delivery irrespective of randomized group. The primary outcome was normal neurodevelopmental outcome at 2 years. Results: Among 511 women randomized, 362/503 (72%) had associated hypertensive conditions. In all, 463/503 (92%) of fetuses survived and cerebral palsy occurred in 6/443 (1%) with known outcome. Among all women there was no difference in outcome based on randomized group; however, of survivors, significantly more fetuses randomized to the late ductus venosus group had a normal outcome (133/144; 95%) than those randomized to computerized cardiotocography alone (111/131; 85%). In 118/310 (38%) of babies delivered

Objective To determine whether maternal allopurinol treatment during suspected fetal hypoxia would reduce the release of biomarkers associated with neonatal brain damage.Design A randomised double-blind placebo controlled multicentre trial.Patients We studied women in labour at term with clinical indices of fetal hypoxia, prompting immediate delivery.Setting Delivery rooms of 11 Dutch hospitals.Intervention When immediate delivery was foreseen based on suspected fetal hypoxia, women were allocated to receive allopurinol 500 mg intravenous (ALLO) or placebo intravenous (CONT).Main outcome measures Primary endpoint was the difference in cord 510013, a tissue-specific biomarker for brain damage.Results 222 women were randomised to receive allopurinol (ALLO, n=111) or placebo (CONT, n=111). Cord S100ss was not significantly different between the two groups: 44.5 pg/mL (IQR 20.2-71.4) in the ALLO group versus 54.9 pg/mL (IQR 26.8-94.7) in the CONT group (difference in median -7.69 (95% Cl -24.9 to 9.52)). Post hoc subgroup analysis showed a potential treatment effect of allopurinol on the proportion of infants with a cord S100ss value above the 75th percentile in girls (ALLO n=5 (12%) vs CONT n=10 (31%); risk ratio (RR) 0.37 (95% Cl 0.14 to 0.99)) but not in boys (ALLO n=18 (32%) vs CONT n=15 (25%); RR 1.4(95% Cl 0.84 to 2.3)). Also, cord neuroketal levels were significantly lower in girls treated with allopurinol as compared with placebo treated girls: 18.0 pg/mL (95% Cl 12.1 to 26.9) in the ALLO group versus 32.2 pg/mL (95% Cl 22.7 to 45.7) in the CONT group (geometric mean difference 16.4(95% Cl 24.6 to 1.64)).Conclusions Maternal treatment with allopurinol during fetal hypoxia did not significantly lower neuronal damage markers in cord blood. Post hoc analysis revealed a potential beneficial treatment effect in girls. Trial registration number NCT00189007, Dutch Trial Register NTR1383.

ObjectiveOur objective is to study the association between potentially influential determinants and first-trimester combined test (FCT) uptake rates in the central region of the Netherlands. MethodsData were extracted from the national prenatal screening database Peridos and the Netherlands Perinatal Registry and compared at the level of the health care provider. Univariable and multivariable linear regression analysis was used to determine the effect of determinants (maternal age, parity, socio-economic status (SES), mode of conception, ethnicity and urbanisation) on uptake. ResultsPrenatal screening data were available for 24657 women and overall uptake rate was 25.7%. The strongest association with FCT uptake was found for advanced maternal age ( 2.2; 95% CI [1.7, 2.8]). Grand multiparity had a significantly negative association with FCT uptake ( -4.3; 95% CI [-5.9, -2.7]). Positive associations were found for very high urbanisation ( 0.3; 95% CI [0.1, 0.4]) and high SES ( 0.2; 95% CI [0.0, 0.3]). ConclusionAdvanced maternal age is strongly associated with participation in prenatal testing. The role of age related risk perception should be incorporated in future policy making to support women in informed and autonomous decision making. The negative association of grand multiparity and FCT might be religion based but requires further research. (c) 2015 John Wiley & Sons, Ltd.

Pregnancy in women with diabetes remains complicated despite improvements in glucose control. This seems mainly due to the fact that normoglycemia is still outside of reach. Congenital malformations are already significantly increased in the case of HbA1c values of 2-4SD above the mean, and fetal macrosomia is increasing in incidence. The latter may be due to an increase in maternal body mass index (BMI), absence of cardiovascular complications, better placentation, and increased weight gain during pregnancy. Severe maternal hypoglycemia is a frequent complication during the first trimester of pregnancy. The outcome is generally poorer in the case of type-2 diabetes as compared to type-1, which is likely to be due to a higher incidence of maternal metabolic syndrome. In this article, preconceptional and antenatal management and the mode and timing of delivery are discussed, both for women with preexisting diabetes and for those with gestational diabetes mellitus.

Introduction: Antidepressant treatment during pregnancy is speedily increasing in developed countries and this phenomenon has occurred without firm evidence on safety and/or efficacy. Aims: The present study investigated from mid-trimester of pregnancy up to 24 hours after birth the pattern of a brain damage marker, namely S100B, in maternal fetal and neonatal biological fluids of pregnant women and their newborns antenatally treated by antidepressant drugs such as selective serotonin re-uptake inhibitors (SSRI). Methods: we conducted an observational study on 75 pregnant women treated in the mid –third trimester by antidepressant drugs and 231 healthy pregnancies. S100B concentrations were measured at 7 predetermined monitoring time-points before, during and after treatment in maternal, fetal and neonatal biological fluids and correlated with neurological follow-up at 7 days from birth. Results: In SSRI group S100B concentrations were significantly higher in SSRI than controls (P

Objective The use of fetal growth charts assumes that the optimal size at birth is at the 50 th birth-weight centile, but interaction between maternal constraints on fetal growth and the risks associated with small and large fetal size at birth may indicate that this assumption is not valid for perinatal mortality rates. The objective of this study was to investigate the distribution and timing (antenatal, intrapartum or neonatal) of perinatal mortality and morbidity in relation to birth weight and gestational age at delivery. Methods Data from over 1 million births occurring at 28–43 weeks’ gestation from singleton pregnancies without congenital abnormalities in the period from 2002 to 2008 were collected from The Netherlands Perinatal Registry. The distribution of perinatal mortality according to birth-weight centile and gestational age at delivery was studied. Results In the 1 170 534 pregnancies studied, there were 5075 (0.43%) perinatal deaths. The highest perinatal mortality occurred in those with a birth weight below the 2.3 rd centile (25.4/1000 births) and the lowest mortality was in those with birth weights between the 80 th and 84 th centiles (2.4/1000 births), according to routinely used growth charts. Antepartum deaths were lowest in those with birth weight between the 90 th and 95 th centiles. Data were almost identical when the analysis was restricted to infants born at ≥ 37 weeks’ gestation. Conclusion From an immediate survival perspective, optimal fetal growth requires a birth weight between the 80 th and 84 th centiles for the population. Median birth weight in the population is, by definition, substantially lower than these centiles, implying that the majority of fetuses exhibit some form of maternal constraint on

Fetal growth restriction (intra-uterine growth restriction [IUGR]) has a considerable impact on perinatal morbidity. Preterm IUGR infants are prone to impaired intestine function. Near-infrared spectroscopy (NIRS) has been used to monitor oxygenation status of the brain and of the intestine.We conducted a prospective case-control study at our NICU in 20 preterm infants of whom 10 infants complicated by compared with 10 non-IUGR preterm infants. Splanchnic and cerebral regional oximetry values were measured with NIRS. Three hours of consecutive recordings were performed in the first 24 h of life, T0, and during the transitional period, T1. The cerebral/splanchnic oxygenation ratio, CSOR, (cerebral regional saturations [rScO2]/splanchnic regional saturations [rSsO2]) was also calculated.Both in the IUGR and the non-IUGR infants, at T0 and T1 monitoring time-points, the rSO2 values were higher in the cerebral district when compared to those of the splanchnic area. Comparison of the NIRS parameters between the IUGR and non-IUGR infants at T0 showed no difference in rScO2, while rSsO2 was significantly lower in the IUGR group. At T1, rScO2 was significantly lower and rSsO2 higher in the IUGR group.Cerebral/splanchnic vascular adaptation of IUGR infants to the extra-uterine environment is characterized by a postnatal persistence of the brain sparing effect with reperfusion in the transitional period.

OBJECTIVE: To study the predictive value of biphasic ST-events for interventions for suspected fetal distress and adverse neonatal outcome, when using ST-analysis of the fetal electrocardiogram (FECG) for intrapartum fetal monitoring. DESIGN: Prospective cohort study. SETTING: Three academic hospitals in Sweden. POPULATION: Women in labor with a high-risk singleton fetus in cephalic position beyond 36 weeks of gestation. METHODS: In women in labor who were monitored with conventional cardiotocography, ST-waveform analysis was recorded and concealed. Traces with biphasic ST-events of the FECG (index) were compared with traces without biphasic events of the FECG. The ability of biphasic events to predict interventions for suspected fetal distress and adverse outcome was assessed using univariable and multivariable logistic regression analyses. MAIN OUTCOME MEASURES: Interventions for suspected fetal distress and adverse outcome (defined as presence of metabolic acidosis (i.e. umbilical cord pH 12 mmol), umbilical cord pH

Contains fulltext : 174756.pdf (Publisher’s version ) (Closed access) INTRODUCTION: Worldwide induction and cesarean delivery rates have increased rapidly, with consequences for subsequent pregnancies. The majority of intrapartum cesarean deliveries are performed for failure to progress, typically in nulliparous women at term. Current uterine registration techniques fail to identify inefficient contractions leading to first-stage labor arrest. An alternative technique, uterine electromyography has been shown to identify inefficient contractions leading to first-stage arrest of labor in nulliparous women with spontaneous onset of labor at term. The objective of this study was to determine whether this finding can be reproduced in induction of labor. MATERIAL AND METHODS: Uterine activity was measured in 141 nulliparous women with singleton term pregnancies and a fetus in cephalic position during induced labor. Electrical activity of the myometrium during contractions was characterized by its power density spectrum. RESULTS: No significant differences were found in contraction characteristics between women with induced labor delivering vaginally with or without oxytocin and women with arrested labor with subsequent cesarean delivery. CONCLUSION: Uterine electromyography shows no correlation with progression of labor in induced labor, which is in contrast to spontaneous labor.

Donor milk (DM) represents an important nutrition source for high-risk newborns. Holder pasteurization (HoP) is the most recommended procedure for DM treatment, providing a good compromise between microbiological safety and biological quality. HoP was previously shown to affect DM cytokines, growth factors and hormones levels, whilst no data concerning the possible effects of HoP on neurobiomarkers (NB) are available. Therefore, our study investigated whether the concentration in DM of a well-known NB involved in brain development/damage, namely S100B, changes due to HoP.We conducted a pretest-test study in 11 mothers, whose DM samples were sub-divided into two parts: the first was immediately frozen (-80 °C); the second was pasteurized with Holder method before freezing. S100B DM levels were measured using a commercially available immunoluminometric assay.S100B protein was detected in all milk samples. Results showed significant differences between groups (p 0.05) in S100B levels after HoP.Our data provide evidence that S100B is present in preterm milk as well as in term milk during maturation degree. Moreover, the results confirm the susceptibility of this neurotrophic factor to pasteurization stresses and the need to develop new storage techniques to preserve the biological quality of human milk.

Electronic fetal heart rate monitoring or cardiotocography (CTG) has been introduced in the 1970s. It has resulted in a 1.6-fold increase in cesarean deliveries (CD; [1]) for fetal distress but has hardly resulted in improvements in neonatal outcome. As stated in an editorial in the American Journal of Obstetrics and Gynecology, “ The hope that this technology would lower the rate of cerebral palsy from intrapartum asphyxia has not materialized. There is, however, reasonable good evidence that CTG does decrease the rate of perinatal mortality, particularly early infant death because of hypoxia” [2]. At term approximately 11,000 labors should be monitored to prevent one early neonatal death and 4,000 to prevent one infant death [3]. In other words, the contribution of CTG to improve perinatal outcome seems rather restricted. And for the prevention of one neonatal death, an extra 700 CDs will have to be performed. In this chapter, the backgrounds of the disappointing effects of CTG monitoring on perinatal outcome are discussed, and suggestions for improvements are given.

Worldwide, there is a rapid increase in deliveries by cesarean section. The large differences among countries, from about 16% to more than 60%, suggest that the cesarean delivery (CD) rate has little to do with evidence-based medicine. In this review, the background for the increasing CD rate is discussed as well as the limited positive effects on neonatal outcome in both term and preterm neonates. Negative effects of CD, including direct maternal morbidity, complications of subsequent pregnancies and iatrogenic early delivery resulting in increased neonatal morbidity, are discussed in addition to long-term implications for the offspring involving altered development of the immune system. The ‘battle' to lower the CD rate will be difficult, but we should not forget that women are designed to deliver vaginally and not by cesarean section.

Five randomized controlled trials have been published on intrapartum fetal heart rate monitoring with ST analysis of the fetal electrocardiogram, but the debate on its usefulness has not yet been ended. We consider ST analysis a useful and cost-effective addition to conventional fetal heart rate monitoring. We will provide support for this opinion by discussing the pathophysiology of ST changes in relation to fetal asphyxia, the results of the randomized controlled trials and numerous meta-analyses of these randomized controlled trials and trends in fetal outcome in hospitals in different countries following the introduction of the ST technology in the labor ward.
