The effect of medical and operative birth interventions on child health outcomes in the first 28 days and up to 5 years of age: A linked data population-based cohort study

Earlier routine induction of labor-Consequences on mother and child morbidity

A growing number of birth interventions had led to a concern for potential health consequences. This study investigates the consequences of earlier routine labor induction. It exploits a natural experiment caused by the introduction of new Danish obstetric guidelines in 2011. Consequently, routine labor induction was moved forward from 14 to 10-13 days past the expected due date (EDD) and extended antenatal surveillance was introduced from 7 days past the EDD. Using administrative data, I find that affected mothers on average had a 9-11 percentage points (32%-38%) higher risk of being induced the following years. Yet, mother and child short- and medium-term morbidity were largely unaffected.

Evidence-based guidelines for intrapartum maternal hydration assessment and management: A scoping review

PROBLEM

Inconsistent practice relating to intrapartum hydration assessment and management is reported, and potential harm exists for laboring women and birthing persons.

BACKGROUND

Labor and birth are physically demanding, and adequate nutrition and hydration are essential for labor progress. A lack of clear consensus on intrapartum hydration assessment and management during labor and birth currently exists. In addition, there is an inconsistent approach to managing hydration, often including a mixture of intravenous and oral fluids that are poorly monitored.

AIM

The aim of this scoping review was to identify and collate evidence-based guidelines for intrapartum hydration assessment and management of maternal hydration during labor and birth.

METHODS

PubMed, Embase, and CINAHL databases were searched, in addition to professional college association websites. Inclusion criteria were intrapartum clinical guidelines in English, published in the last 10 years.

FINDINGS

Despite searching all appropriate databases in maternity care, we were unable to identify evidence-based guidelines specific to hydration assessment and management, therefore resulting in an "empty review." A subsequent review of general intrapartum care guidelines was undertaken. Our adapted review identified 12 guidelines, seven of which referenced the assessment and management of maternal hydration during labor and birth. Three guidelines recommend that "low-risk" women in spontaneous labor at term should hold determination over what they ingest in labor. No recommendations with respect to assessment and management of hydration for women undergoing induction of labor were found.

DISCUSSION

Despite the increasing use of intravenous fluid as an adjunct to oral intake to maintain maternal intrapartum hydration, there is limited evidence and, subsequently, guidelines to determine best practice in this area. How hydration is assessed was also largely absent from general intrapartum care guidelines, further perpetuating potential clinical variation in this area.

CONCLUSION

There is an absence of guidelines specific to the assessment and management of maternal hydration during labor and birth, despite its importance in ensuring labor progress and safe care.

Fetal Heart Rate Auscultation, 4th Edition

Intermittent auscultation (IA) is an evidence-based method of fetal surveillance during labor for birthing people with low-risk pregnancies. It is a central component of efforts to reduce the primary cesarean rate and promote vaginal birth (American College of Obstetricians and Gynecologists, 2019; Association of Women's Health, Obstetric and Neonatal Nurses, 2022a). The use of intermittent IA decreased with the introduction of electronic fetal monitoring, while the increased use of electronic fetal monitoring has been associated with an increase of cesarean births. This practice monograph includes information on IA techniques; interpretation and documentation; clinical decision-making and interventions; communication; education, staffing, legal issues; and strategies to implement IA.

A Higher Maternal Education Level Could Be a Critical Factor in the Exceeded Cesarean Section Delivery in Indonesia

Background

Cesarean section (CS) could be life-saving with medically indicated, but without it, both women and children could be at risk. The maximum rate for CS is 15%, but it tends to exceed globally.

Objective

We aimed to analyze the education level's role in the delivery of CS in Indonesia.

Methods

We used the 2017 Indonesia Demographic and Health Survey data. The study sampled 15,357 women who delivered in five last years. Besides delivery mode and education level, the study also used nine control variables: residence, age, marital, employment, parity, wealth, insurance, antenatal care, and birth type. The study employed a binary logistics regression.

Results

The results show women with secondary education (16.5% CS) are 2.174 times (AOR 2.174; 95% CI 1.095-4.316), and higher education (33% CS) are 3.241 (AOR 3.241; 95% CI 1.624-6.469) times more likely to deliver by CS than no-school education (4.4% CS). There was no significant difference between primary (9.1%) and no-education women. Apart from education, primiparous women, age 34-34 yr, attending antenatal care ≥4 times, non-poorest, having insurance, living in the city, and being unemployed also related to higher risk of CS.

Conclusion

Exceeded CS in Indonesia occurs mostly in higher education women. Higher education women were more likely to access more information and technology, therefore health promotion on healthy normal birth on social media or m-Health (mobile device-based health promotion) and involving health authorities at every level were suitable to reduce the overuse of the CS.

Association of cesarean section with asthma in children/adolescents: a systematic review and meta-analysis based on cohort studies

BACKGROUND

Whether cesarean section (CS) is a risk factor for asthma in offspring is controversial. The purpose of this study was to investigate the association between CS and asthma in children/adolescents.

METHODS

Pubmed, Embase, Web of Science, and Cochrane Library electronic databases were searched for cohort studies on the relationship between mode of delivery and asthma in children/adolescents up to February 2023. Birth via CS was considered an exposure factor. Asthma incidence was taken as a result.

RESULTS

Thirty-five cohort studies (thirteen prospective and twenty-two retrospective cohort studies) were included. The results showed that the incidence of asthma was higher in CS offspring (odds ratio (OR) = 1.18, P < 0.001) than in the vaginal delivery (VD) group. Partial subgroup analyses showed a higher incidence of asthma in female offspring born via CS (OR = 1.26, P < 0.001) compared with the VD group, while there was no difference in males (OR = 1.07, P = 0.325). Asthma incidence was higher in CS offspring than in the VD group in Europe (OR = 1.20, P < 0.001), North America (OR = 1.15, P < 0.001), and Oceania (OR = 1.06, P = 0.008). This trend was not found in the Asian population (OR = 1.17, P = 0.102). The incidence of atopic asthma was higher in offspring born via CS (OR = 1.14, P < 0.001) compared to the VD group. The CS group had a higher incidence of persistent asthma, but the difference did not reach statistical significance (OR = 1.15, P = 0.063).

CONCLUSION

In this meta-analysis, CS may be a risk factor for asthma in offspring children/adolescents compared with VD. The relationship between CS and asthma was influenced by sex and region.

Hyperbilirubinemia and Associated Factors Among Neonates Admitted to the Neonatal Care Unit in Jimma Medical Center

Background

Neonatal hyperbilirubinemia is a widespread and significant clinical problem among neonates worldwide. Globally, every year about 1.1 million babies develop it and the vast majority reside in South Asia and sub-Saharan Africa. Studies on the magnitude and factors associated with neonatal hyperbilirubinemia are limited in Ethiopia. So this study was aimed at assessing the prevalence and associated factors of neonatal hyperbilirubinemia among hospitalized neonates in the neonatal intensive care unit of Jimma Medical Center (JMC), Jimma, South West Ethiopia.

Design

Hospital-based cross-sectional study was conducted at JMC from July 24 to October 19, 2020.

Methods

A total of 222 neonates with their mothers were included and conveniently selected. Data was collected by interviewing mothers through structured questionnaires and reviewing neonates' medical records using a checklist. Multivariable binary logistic regression analyses were employed to identify factors associated with neonatal hyperbilirubinemia.

Results

from a total of neo-maternal pairs included in the studies; the proportion of Neonatal hyperbilirubinemia was found to be 94 (42.3%). Neo-maternal ABO incompatibility 33 (35.1%), prematurity 41 (43.6%), sepsis 35 (37.2%), Neonatal birth asphyxia 20 (21.2%), and Rh isoimmunization 10 (10.6%) was significantly associated with neonatal hyperbilirubinemia.

Conclusion

The prevalence of neonatal hyperbilirubinemia in the study setting was high. Antenatal care (including both mother and fetus detail examination and follow-ups) as well as cautions during labor need to focus on since Neonatal hyperbilirubinemia-associated factors were maternal and neonatal. Hence, further assessment, early intervention, and timely treatment are important to mitigate the burdens in neonates due to hyperbilirubinemia.

Short-term and long-term effects of cesarean section on asthma and wheezing: A cohort study and meta-analysis

OBJECTIVE

To describe the short-term and long-term effects of cesarean section on childhood asthma and wheezing.

METHOD

Firstly, in the cohort study, 6640 infants were included in the cohort baseline from January 2018 to December 2019, in which 6501 children completed the follow-up study for respiratory diseases at age 2 years. The effect of cesarean section on asthma and wheezing was estimated by the logistic regression model. Secondly, we conducted a meta-analysis of studies with outcomes of childhood asthma and wheezing under 2 years of age and over 2 years of age, respectively, to investigate the short-term and long-term effects of cesarean section on asthma and wheezing.

RESULTS

In our cohort study, the cumulative incidence of asthma and wheezing was 1.3% (84/6501). 45.5% of children (2961/6501) were born by cesarean section. The adjusted odds ratio for the effect of cesarean section on asthma and wheezing in children under 2 years of age was 1.14 (95%CI 0.73-1.78). Combining previous studies (outcomes of asthma and wheezing under 2 years of age) with our results for a meta-analysis, the odds ratio was 1.15 (95%CI 1.05-1.25, I² = 46.82%). Meanwhile, cesarean section had a long-term effect on asthma and wheezing in the child population over 2 years of age (OR = 1.17, 95%CI 1.11-1.24, P < 0.001, I² = 79.38%).

CONCLUSION

Cesarean section had a short-term effect on asthma and wheezing before the age of 2, in addition, the long-term effect of cesarean section on asthma and wheezing persisted in the child population (under 18).

Does a three-hour delayed pushing benefit the mode of delivery?

OBJECTIVE

The objective of this study was to compare two strategies for passive second stage management: three-hour vs two-hour delayed pushing after the diagnosis of full cervical dilation on mode of delivery and perinatal outcomes.

STUDY DESIGN

This retrospective observational study included low-risk nulliparous women who reatched full cervical dilation under epidural analgesia with a single term fetus in cephalic presentation and normal fetal heart rate, between September and December 2016. Mode of delivery (spontaneous vaginal delivery versus operative delivery including cesarean section and instrumental vaginal delivery) and perinatal outcomes (post-partum hemorrhage, perineal lacerations, 5-min Apgar score, umbilical cord pH and transfer to neonatal intensive care unit) were compared between two maternity units: maternity unit A, where women could have up to a three-hour delayed pushing period after full cervical dilation diagnosis, and maternity unit B, where the delayed pushing period was a maximum of 2 hours. Outcomes were compared using univariate and multivariable analyses. Adjusted odds ratios (aOR) were estimated using a logistic regression multivariable model that included potential cofounders.

RESULTS

During the study period, 614 women were included, 305 in maternity unit A and 309 in maternity unit B. Women's pre-existing characteristics were comparable between the two maternity units. Women delivering in the maternity unit A had significantly lower risks of having an operative delivery compared to women delivering in the maternity unit B (respectively 18.4 vs 26.9%; aOR = 0.64; 95%CI [0.43 - 0.96]). Perinatal outcomes were comparable in the two maternity units, particularly in terms of post-partum hemorrhage rates (7.4 vs 7.8%; aOR = 1,19 [0.65 - 2.19]).

CONCLUSION

Increasing the possible length of the delayed pushing period from 2 to 3 hours after the diagnosis of full cervical dilation in low-risk nulliparous women appears to reduce operative deliveries without adverse effects on maternal or neonatal morbidity.

Impact of the Thompson method on breastfeeding exclusivity and duration: Multi-method design

BACKGROUND

How hospital clinicians facilitate breastfeeding in the first 48-72 h is critical to breastfeeding exclusivity and duration. Mothers who discharge hospital directly breastfeeding are more likely to continue exclusively breastfeeding at 3-months.

OBJECTIVE

To assess the impact of facility-wide implementation of a physiological breastfeeding method (the Thompson method) on direct breastfeeding at hospital discharge and exclusive breastfeeding at 3-months of age.

DESIGN

Multi-method design using interrupted time series analysis and surveys.

SETTING(S)

An Australian tertiary maternity hospital.

PARTICIPANTS

13,667 mother-baby pairs (interrupted time series analysis) and 495 postnatal mothers (surveys).

METHODS

The Thompson method includes cradle position and hold, alignment of mouth-to-nipple, baby-led connection and seal, maternal fine-tuning for symmetry, and leisurely duration. We used a large pre-post implementation dataset and conducted interrupted time series analysis using a 24-month baseline period (January 2016 - December 2017); and a 15-month post-implementation period (April 2018 - June 2019). We recruited a sub-sample of women to complete surveys at hospital discharge and 3-months postpartum. Surveys were primarily used to measure impact of Thompson method on exclusive breastfeeding at 3-months, compared with a baseline survey conducted in same setting.

RESULTS

Following implementation of the Thompson method, the declining trend in direct breastfeeding at hospital discharge was significantly averted by 0.39% each month relative to baseline (95% CI: 0.03% to 0.76%; p = 0.037). While the 3-month exclusive breastfeeding rate in the Thompson group was 3 percentage points higher than the baseline group; this result did not reach statistical significance. However, a subgroup analysis of women who discharged hospital exclusively breastfeeding revealed the relative odds of exclusive breastfeeding at 3-months in the Thompson group was 0.25 (95% CI: 0.17 to 0.38; p < 0.001), significantly better than the baseline group (Z = 3.23, p < 0.01) where the relative odds was only 0.07 (95% CI: 0.03 to 0.19; p < 0.001).

CONCLUSIONS

Implementation of the Thompson method for well mother-baby pairs improved direct breastfeeding trends at hospital discharge. For women who discharged hospital exclusively breastfeeding, exposure to the Thompson method reduced the risk of exclusive breastfeeding discontinuation by 3-months. The positive impact of the method was potentially confounded by partial implementation and a parallel rise in birth interventions which undermine breastfeeding. We recommend strategies to strengthen clinician buy-in to the method, and future research using a cluster randomised trial design.

TWEETABLE ABSTRACT

Facility-wide implementation of the Thompson method improves direct breastfeeding at hospital discharge and predicts breastfeeding exclusivity at 3-months.

Parto por cesárea y su asociación con el síndrome obstructivo bronquial agudo en pacientes de 12 a 36 meses de edad

Objetivo. Identificar la asociación entre partos por cesárea y el Síndrome obstructivo bronquial agudo (SOBA) en pacientes de 12 a 36 meses de edad hospitalizados en el Hospital de Vitarte-MINSA durante el año 2017-2019. Material y métodos. Se realizó un estudio analítico, retrospectivo, de casos y controles. La población estudiada fueron los pacientes de 12-36 meses de edad hospitalizados durante el año 2017-2019, conformada por 306 niños siendo 102 casos y 204 controles (1:2). Los datos a estudiar se obtuvieron de la historia clínica donde se registró las siguientes variables: edad, sexo, cesárea, APGAR, edad gestacional, lactancia materna, vacunación, hacinamiento y número de hermanos. Resultados. La población de estudio estuvo conformada principalmente por niños de 1 año de edad (53,27%) de sexo femenino (52,29%). El parto por cesárea representó el 41,18% de los nacimientos y se asoció a la presencia de SOBA (OR=2,50; IC95%=1,51-4,15; p<0,001) en comparación con el parto vaginal. De mismo modo se encontró asociación entre lactancia materna exclusiva (OR=0,42; IC 95%=0,23-0,78; p=0,006), vacunación (OR=0,56; IC 95%=0,33-0,94; p=0,027) y hacinamiento (OR=1,77; IC 95%=1,04-3,01; p=0,034); sin embargo, no hubo diferencia estadística entre la edad (p=0,343; IC95%=0,62-1,18%), sexo (p=0,871; IC95%=0,42-1,29), edad gestacional (p=0,164; IC95%=0,71-1,06), APGAR (p=0,685; IC95%=0,73-1,23) y número de hermanos (p=0,357; IC95%=0,89-1,39). Conclusión. El parto por cesárea se encuentra asociado al desarrollo del SOBA. Presentando 2 veces mayor riesgo de padecerlo si se nace por cesárea, esto debido a que causa un deterioro del sistema inmune.

Estimating the effect of cesarean delivery on long-term childhood health across two countries

Assessing the impact of cesarean delivery (CD) on long-term childhood outcomes is challenging as conducting a randomized controlled trial is rarely feasible and inferring it from observational data may be confounded. Utilizing data from electronic health records of 737,904 births, we defined and emulated a target trial to estimate the effect of CD on predefined long-term pediatric outcomes. Causal effects were estimated using pooled logistic regression and standardized survival curves, leveraging data breadth to account for potential confounders. Diverse sensitivity analyses were performed including replication of results in an external validation set from the UK including 625,044 births. Children born in CD had an increased risk to develop asthma (10-year risk differences (95% CI) 0.64% (0.31, 0.98)), an average treatment effect of 0.10 (0.07-0.12) on body mass index (BMI) z-scores at age 5 years old and 0.92 (0.68-1.14) on the number of respiratory infection events until 5 years of age. A positive 10-year risk difference was also observed for atopy (10-year risk differences (95% CI) 0.74% (-0.06, 1.52)) and allergy 0.47% (-0.32, 1.28)). Increased risk for these outcomes was also observed in the UK cohort. Our findings add to a growing body of evidence on the long-term effects of CD on pediatric morbidity, may assist in the decision to perform CD when not medically indicated and paves the way to future research on the mechanisms underlying these effects and intervention strategies targeting them.

The social organisation of decision-making about intrapartum fetal monitoring: An Institutional Ethnography

BACKGROUND

International guidelines recommend intrapartum cardiotocograph (CTG) monitoring for women at risk for poor perinatal outcome. Research has not previously addressed how midwives and obstetricians enable or hinder women's decision-making regarding intrapartum fetal monitoring and how this work is structured by external organising factors.

AIM

To examine impacts of policy and research texts on midwives' and obstetricians' work with labouring women related to intrapartum fetal monitoring decision-making.

METHODS

We used a critical feminist qualitative methodology known as Institutional Ethnography (IE). The research was conducted in an Australian tertiary maternity service. Data collection included interviews, observation, and texts relating to midwives' and obstetricians' work with the fetal monitoring system. Textual mapping was used to explain how midwives' and obstetricians' work was organised to happen the way it was.

FINDINGS

CTG monitoring was initiated predominantly by midwives applying mandatory policy. Midwives described reluctance to inform labouring women that they had a choice of fetal monitoring method. Discursive approaches used in a national fetal surveillance guideline, a Cochrane systematic review, and the largest randomised controlled trial regarding CTG monitoring in labour generated and reproduced assumptions that clinicians, not labouring women, were the appropriate decision-maker regarding fetal monitoring in labour.

DISCUSSION AND CONCLUSION

Guidelines structured midwives' and obstetricians' work in a manner that undermined women's participation in decisions about fetal monitoring method. Intrapartum fetal monitoring guidelines should be critically reviewed to ensure they encourage and enable midwives and obstetricians to support women to make decisions about intrapartum care.

Morbidity and psychomotor development of offspring of women with gestational diabetes: a 5-year follow-up

Background

Gestational diabetes mellitus (GDM) represents a risk factor for both mother and her offspring in a short-term (perinatal morbidity) and long-term horizon (postpartum diabetes or foetal programming). Several studies focused at peri/postnatal outcomes of GDM mother´s offspring, however relatively few (and none in Czech population) were designed as prospective. The aim of the study was to ascertain eventual anthropometric and developmental abnormalities and/or morbidity in offspring of GDM mothers compare to controls in a 5-year follow-up using a parent-reported parameters related to psychomotor development and common paediatric morbidities including a sub-study of offspring of GDM mothers experiencing adverse perinatal outcomes.

Methods

A 5 year follow up study of offspring of GDM mothers (n = 26) vs those with a normal pregnancy (n = 63). An electronic questionnaire was used to obtain the parameters (such as growth, psychomotor development, vaccination, morbidity history etc.) available to parents from the parent-held infant health record. Data on pregnancy and delivery were available from the previous study.

Results

Offspring of GDM mothers had delayed psychomotor development in early childhood, but in 5 years of age they seemed to gradually achieve results of a control group. Children with macrosomia had a higher percentile of weight-for-height and were significantly more frequently ill than those with a normal birth weight. Offspring of obese mothers had worse verbal language skills in early childhood and a higher percentile of weight-for-height.

Conclusion

Maternal gestational diabetes and obesity can be considered an important determinant of postnatal offspring development and health status, which further advocates for broader implementation of preventive strategies.

A true choice of place of birth? Swiss women’s access to birth hospitals and birth centers

While the place of birth plays a crucial role for women’s birth experiences, the interest in out-of-hospital births has increased during the Covid-19 pandemic. Related to this, various international policies recommend enabling women to choose where to give birth. We aimed to analyze Swiss women’s choice between birth hospitals and birth centers. Employing spatial accessibility analysis, we incorporated four data types: highly disaggregated population data, administrative data, street network data, addresses of birth hospitals and birth centers. 99.8% of Swiss women of childbearing age were included in the analysis (N = 1.896.669). We modelled car travel times from a woman’s residence to the nearest birth hospital and birth center. If both birth settings were available within 30 minutes, a woman was considered to have a true choice. Only 58.2% of women had a true choice. This proportion varied considerably across Swiss federal states. The main barrier to a true choice was limited accessibility of birth centers. Median travel time to birth hospitals was 9.8 (M = 12.5), to birth centers 23.9 minutes (M = 28.5). Swiss women are insufficiently empowered to exercise their reproductive autonomy as their choice of place of birth is significantly limited by geographical constraints. It is an ethical and medical imperative to provide women with a true choice. We provide high-resolution insights into the accessibility of birth settings and strong arguments to (re-)examine the need for further birth centers (and birth hospitals) in specific geographical areas. Policy-makers are obligated to improve the accessibility of birth centers to advance women’s autonomy and enhance maternal health outcomes after childbirth. The Covid-19 pandemic offers an opportunity to shift policy.

Association between screening for antenatal depressive symptoms and delivery outcomes: The Born in Queensland Study

BACKGROUND

Evidence shows that depressive symptoms during pregnancy increase the risk of an intervention during delivery (induction, the use of forceps or vacuum, and caesarean sections (CS)). Many women with depression during pregnancy are not identified and therefore will not receive appropriate follow up of their symptoms. We hypothesised that routine screening for depressive symptoms during pregnancy could reduce detrimental consequences of depressive symptoms on delivery outcomes.

AIM

We explored the association between screening for depressive symptoms during pregnancy and delivery outcomes.

MATERIALS AND METHODS

A cross-sectional analysis of state-wide administrative data sets. The population included all women who delivered a singleton in Queensland between the July and December of 2015. Logistic regression analyses were run in 27 501 women (93.1% of the total population) with information in all variables. The following were the main outcomes: onset of labour, CS, instrumental vaginal delivery, and all operative deliveries (including both CS and instrumental vaginal deliveries).

RESULTS

Women who completed the screening had increased odds of a spontaneous onset of labour (adjusted odds ratio (aOR) 1.18; 95% CI 1.09-1.27) and decreased odds of an operative delivery (instrumental or CS) (aOR 0.88; 95% CI 0.81-0.96). Among women who had a vaginal delivery, those who completed the screening had decreased odds of having an instrumental delivery (aOR 0.84; 95% CI 0.74-0.97). Sensitivity analyses in women who did not have a formal diagnosis of depression showed similar results.

CONCLUSION

Our findings suggest that screening may decrease interventions during delivery in women with depressive symptoms.

Cesarean delivery on maternal request and common child health outcomes: A prospective cohort study in China

Background

Cesarean delivery vs vaginal delivery was reported to increase the risks of childhood obesity, pneumonia, anemia, and neurobehavioral disorders, but few studies were able to deal with the confounding biases associated with medical conditions indicating cesareans. This prospective cohort study aims to investigate the associations of non-medically indicated cesarean delivery on maternal request (CDMR) with these child health outcomes.

Methods

Among 17 748 liveborn infants whose mothers (primiparas) participated in a randomized controlled trial on micronutrient supplementation and pregnancy outcomes during 2006-2009 in 5 rural counties in Hebei Province, China, 6972 singletons born by full-term spontaneous vaginal delivery (SVD) and 3626 by CDMR were extracted for the assessments of obesity (weight-for-height z-score >3) and pneumonia (self-reported) at 1.5-5 years in 2011. Some children were further randomly selected from these two groups for the assessments of anemia (hemoglobin <110 g/L, 2341 SVD and 2417 CDMR) and neurobehavioral disorders (raw score of Child Behavior Checklist larger than the 90th percentile of the normative sample, 1257 SVD and 1060 CDMR).

Results

Compared with SVD, CDMR was associated with increased risks of obesity (adjusted odds ratio (aOR) = 1.41, 95% confidence interval (CI) = 1.14-1.75, P = 0.002) and anemia (aOR = 1.65, 95% CI = 1.28-2.12, P < 0.001), but not with the risk of pneumonia (aOR = 1.16, 95% CI = 0.94-1.45, P = 0.17) or neurobehavioral disorders (aORs varied from 0.82 to 0.91, P > 0.05) in childhood.

Conclusions

Cesarean delivery, independent of cesarean indications, is likely associated with childhood obesity and anemia, indicating a need to keep pregnant women informed, especially those seeking CDMR, a need to explore possible improvement on obstetric service, and even a need for main stakeholders to reach a compromise in making a cesarean decision.

Realigning Expectations With Reality: A Case Study on Maternal Mental Health During a Difficult Breastfeeding Journey

INTRODUCTION

Many mothers have the goal to breastfeed. However, more than 50% will have breastfeeding difficulty by the 3rd day of life. Mothers who are unable to meet their breastfeeding goals are at higher risk for anxiety, depression, embarrassment, and guilt. Those who stop breastfeeding need support and help resolving these feelings. This case study aims to describe one woman's difficulty with mental health surrounding breastfeeding, her decision to bottle feed, and her successful transition back to direct breastfeeding.

MAIN ISSUE

Barriers to the participant's success with breastfeeding were pre-existing history of depression/anxiety, forceps delivery, uncontrolled perineal pain, infant physical trauma, and nipple/flow confusion. The decision to discontinue direct breastfeeding and start bottle feeding came after 2 months of anxiety, frustration, and persistence.

MANAGEMENT

The participant followed her healthcare team's recommendations of triple feeding, lactation support groups, pediatric chiropractic adjustments, and prescribed galactagogues. After 2 months of exhaustion and deliberation, she made the difficult decision to stop breastfeeding for nutritional benefits and switched to breastfeeding only for her infant's pleasure and comfort. Lowered expectations allowed the dyad to heal and her son to transition to nearly exclusive breastfeeding at 4 months of life.

CONCLUSION

Clinicians must be aware of the delicate balance between promoting breastfeeding for its nutritional value and health benefits and supporting a struggling mother with mental health needs.

Maternal and fetal hypothermia: more preventive compliance is required for a mother and her fetus while undergoing cesarean delivery; a quality improvement review

OBJECTIVE

Cesarean delivery is common, involves two patients, has numerous multi-disciplinary health care providers involved in the delivery management, but has variable levels of anesthesia and health services implementation for decreasing maternal hypothermia and the maternal and neonatal morbidity (and mortality). Limited implementation for either of the ERAS-CD or the ERAC guidelines, for inadvertent or preventive maternal hypothermia, is likely to be occurring on labor delivery floors. This Quality Improvement (QI) review focuses on cesarean delivery and maternal hypothermia.

METHODS

This quality and safety initiative used SQUIRE 2.0 methodology and concurrent PubMed searches to identify systematic review, meta-analysis, topic directed studies, additional published cohorts in the topic area not included in SR/MA, limited case reports that had specific clinical outcomes related to maternal hypothermia and fetal effects.

RESULTS

Two quality and safety improvement guidelines have defined the hypothermia activity element differently, with ERAS-CD recommending to prevent hypothermia, while ERAC recommending to maintain normothermia. The peer-reviewed literature indicates that the knowledge associated with surgical hypothermia outcome is known but it is not implemented for maternal cesarean delivery care. Increased maternal-effect recognition, surveillance, triage, and evidenced-based protocol management is required for the maternal - neonatal dyad undergoing cesarean delivery for the clinical reduction/prevention of neonatal hypothermia that has proven evidence-based maternal morbidity and neonatal morbidity/mortality.

CONCLUSION

TEAM-based anesthesia, obstetrical, neonatology-pediatrics and nursing research collaboration is required through quality-safety-ERAS-ERAC directed processes. Healthcare system recognition and financial support is required for maternal-fetal-neonatal hypothermia prevention protocols implementation.

Postpartum women's experiences of social and healthcare professional support during the COVID-19 pandemic: A recurrent cross-sectional thematic analysis

Problem

Disrupted access to social and healthcare professional support during the COVID-19 pandemic have had an adverse effect on maternal mental health.

Background

Motherhood is a key life transition which increases vulnerability to experience negative affect.

Aim

Explore UK women’s postnatal experiences of social and healthcare professional support during the COVID-19 pandemic.

Methods

Semi-structured interviews were conducted with 12 women, approximately 30 days after initial social distancing guidelines were imposed (T1), and a separate 12 women were interviewed approximately 30 days after the initial easing of social distancing restrictions (T2). Recurrent cross-sectional thematic analysis was conducted in NVivo 12.

Findings

T1 themes were, ‘Motherhood has been an isolating experience’ (exacerbated loneliness due to diminished support accessibility) and ‘Everything is under lock and key’ (confusion, alienation, and anxiety regarding disrupted face-to-face healthcare checks). T2 themes were, ‘Disrupted healthcare professional support’ (feeling burdensome, abandoned, and frustrated by virtual healthcare) and ‘Easing restrictions are bittersweet’ (conflict between enhanced emotional wellbeing, and sadness regarding lost postnatal time).

Discussion

Respondents at both timepoints were adversely affected by restricted access to informal (family and friends) and formal (healthcare professional) support, which were not sufficiently bridged virtually. Additionally, the prospect of attending face-to-face appointments was anxiety-provoking and perceived as being contradictory to social distancing guidance. Prohibition of family from maternity wards was also salient and distressing for T2, but not T1 respondents.

Conclusion

Healthcare professionals should encourage maternal help-seeking and provide timely access to mental health services. Improving access to informal and formal face-to-face support are essential in protecting maternal and infant wellbeing.

The association between birth by caesarean section at term and offspring cognitive and academic performance: A birth cohort study

BACKGROUND

Caesarean section (CS) is associated with an increased risk of adverse health outcomes for both mothers and offspring. The evidence for an association between CS and reduced offspring cognitive and academic performance has been inconsistent, with considerable limitations.

AIM

The aim of this study is to compare cognitive and academic performance in childhood and early adulthood in offspring delivered by CS with those delivered vaginally at term.

MATERIALS AND METHODS

Data on 4327 mothers and offspring from a longitudinal birth cohort study were analysed. Offspring cognitive performance was measured by the Picture Peabody Vocabulary Test-Revised (PPVT-R) at ages five and 21 and the Raven's Standard Progressive Matrices at age 14. Academic achievement was assessed using the Wide Range Achievement Test at age 14.

RESULTS

After adjustment for confounding factors, there was no statistically significant association between cognitive performance and offspring birth mode at age five (P = 0.11). The adjusted difference of mean scores at five years on the PPVT-R for elective CS birth compared to those born by vaginal delivery was -2.2 (95% confidence interval (CI) -4.3 to -0.2), whereas for emergency CS it was 0.0 (95% CI -2.0 to 2.0). There were no differences in cognitive or academic performance at ages 14 and 21.

CONCLUSION

Birth mode was not significantly associated with offspring cognitive or academic performance. Our study does not support concerns that CS is associated with a reduction in cognitive performance.

Oral administration of maternal vaginal microbes at birth to restore gut microbiome development in infants born by caesarean section: A pilot randomised placebo-controlled trial

BACKGROUND

Birth by caesarean section (CS) is associated with aberrant gut microbiome development and greater disease susceptibility later in life. We investigated whether oral administration of maternal vaginal microbiota to infants born by CS could restore their gut microbiome development in a pilot single-blinded, randomised placebo-controlled trial (Australian New Zealand Clinical Trials Registry, ACTRN12618000339257).

METHODS

Pregnant women scheduled for a CS underwent comprehensive antenatal pathogen screening. At birth, healthy neonates were randomised to receive a 3 ml solution of either maternal vaginal microbes (CS-seeded, n = 12) or sterile water (CS-placebo, n = 13). Vaginally-born neonates were used as the reference control (VB, n = 22). Clinical assessments occurred within the first 2 h of birth, and at 1 month and 3 months of age. Infant stool samples and maternal vaginal extracts from CS women underwent shotgun metagenomic sequencing. The primary outcome was gut microbiome composition at 1 month of age. Secondary outcomes included maternal strain engraftment, functional potential of the gut microbiome, anthropometry, body composition, and adverse events.

FINDINGS

Despite the presence of viable microbial cells within transplant solutions, there were no observed differences in gut microbiome composition or functional potential between CS-seeded and CS-placebo infants at 1 month or 3 months of age. Both CS groups displayed the characteristic signature of low Bacteroides abundance, which contributed to a number of biosynthesis pathways being underrepresented when compared with VB microbiomes. Maternal vaginal strain engraftment was rare. Vaginal seeding had no observed effects on anthropometry or body composition. There were no serious adverse events associated with treatment.

INTERPRETATION

Our pilot findings question the value of vaginal seeding given that oral administration of maternal vaginal microbiota did not alter early gut microbiome development in CS-born infants. The limited colonisation of maternal vaginal strains suggest that other maternal sources, such as the perianal area, may play a larger role in seeding the neonatal gut microbiome.

"My whole room went into chaos because of that thing in the corner": Unintended consequences of a central fetal monitoring system

OBJECTIVE

Technologies for fetal heart rate monitoring have been widely introduced despite evidence of no improvement in perinatal outcomes. A significant body of research has raised concerns that healthcare information technologies can have unintended consequences. We sought to describe an unintended consequence of central fetal monitoring technology.

DESIGN

The research was conducted as an Institutional Ethnography. Data generated from interviews, focus groups, and observations were analysed to generate an account of midwives' experiences with the central fetal monitoring system.

SETTING

The birthing unit of one Australian maternity service with a central fetal monitoring system.

INFORMANTS

34 midwives and midwifery students who worked with the central fetal monitoring system.

FINDINGS

Midwives described a disruptive social event they named being K2ed. Clinicians responded to perceived cardiotocograph abnormalities by entering the birth room despite the midwife not having requested assistance. Being K2ed disrupted midwives' clinical work and generated anxiety. Clinical communication was undermined, and midwives altered their clinical practice. Midwives performed additional documentation work to attempt to avoid being K2ed.

KEY CONCLUSIONS

This is the first report of an unintended consequence relating to central fetal monitoring, demonstrating how central fetal monitoring technology potentially undermines safety by impacting on clinical and relational processes and outcomes in maternity care.

IMPLICATIONS FOR PRACTICE

Current evidence does not support implementation or ongoing use of central fetal monitoring systems. Further research is needed to inform scaling down central fetal monitoring systems in a safe and supported way.

Neonatal BCG vaccination and infections in the first year of life: the MIS BAIR randomised controlled trial

BACKGROUND

Bacille Calmette-Guérin (BCG) vaccination has beneficial off-target effects that may include protecting against non-mycobacterial infectious diseases. We aimed to determine whether neonatal BCG vaccination reduces lower respiratory tract infections (LRTI) in infants in the MIS BAIR trial.

METHODS

In this investigator-blinded trial, neonates in Australia were randomised to receive BCG-Denmark vaccination or no BCG at birth. Episodes of LRTI were determined by symptoms reported in parent-completed 3-monthly questionnaires over the first year of life. Data were analysed by intention-to-treat using binary regression. Clinicaltrials.gov (NCT01906853).

RESULTS

From August 2013 to September 2016, 1272 neonates were randomised to the BCG vaccination (n=637) or control (n=635) group. The proportion of participants with an episode of LRTI in the first year of life among BCG-vaccinated infants was 54.8% compared to 58.0% in the control group, resulting in a risk difference of -3.2 (95% CI -9.0 to 2.6) after multiple imputation. There was no interaction observed between the primary outcome and sex, maternal BCG or the other pre-specified effect modifiers.

CONCLUSIONS

Based on the findings of this trial, there is insufficient evidence to support the use of neonatal BCG vaccination to prevent LRTI in the first year of life in high-income settings.

Intrapartum interventions and outcomes for women and children following induction of labour at term in uncomplicated pregnancies: a 16-year population-based linked data study

OBJECTIVES

We compared intrapartum interventions and outcomes for mothers, neonates and children up to 16 years, for induction of labour (IOL) versus spontaneous labour onset in uncomplicated term pregnancies with live births.

DESIGN

We used population linked data from New South Wales, Australia (2001-2016) for healthy women giving birth at 37+0 to 41+6 weeks. Descriptive statistics and logistic regression were performed for intrapartum interventions, postnatal maternal and neonatal outcomes, and long-term child outcomes adjusted for maternal age, country of birth, socioeconomic status, parity and gestational age.

RESULTS

Of 474 652 included births, 69 397 (15%) had an IOL for non-medical reasons. Primiparous women with IOL versus spontaneous onset differed significantly for: spontaneous vaginal birth (42.7% vs 62.3%), instrumental birth (28.0% vs 23.9%%), intrapartum caesarean section (29.3% vs 13.8%), epidural (71.0% vs 41.3%), episiotomy (41.2% vs 30.5%) and postpartum haemorrhage (2.4% vs 1.5%). There was a similar trend in outcomes for multiparous women, except for caesarean section which was lower (5.3% vs 6.2%). For both groups, third and fourth degree perineal tears were lower overall in the IOL group: primiparous women (4.2% vs 4.9%), multiparous women (0.7% vs 1.2%), though overall vaginal repair was higher (89.3% vs 84.3%). Following induction, incidences of neonatal birth trauma, resuscitation and respiratory disorders were higher, as were admissions to hospital for infections (ear, nose, throat, respiratory and sepsis) up to 16 years. There was no difference in hospitalisation for asthma or eczema, or for neonatal death (0.06% vs 0.08%), or in total deaths up to 16 years.

CONCLUSION

IOL for non-medical reasons was associated with higher birth interventions, particularly in primiparous women, and more adverse maternal, neonatal and child outcomes for most variables assessed. The size of effect varied by parity and gestational age, making these important considerations when informing women about the risks and benefits of IOL.

Trends and characteristics of women undergoing induction of labour in a tertiary hospital setting: A cross-sectional study

BACKGROUND

In many well-resourced countries, rising rates of intervention are being observed during pregnancy, labour and childbirth with induction of labour (IOL) fast becoming one of the most common. In Australia, the rate of induction of labour has increased by over 30% since 2007, and today one in three women have their labours induced. We do not however have a good understanding of the contribution of specific obstetric populations to this trend.

METHODS

We examine the contribution of specific obstetric populations to induction of labour over a six-year period at one tertiary maternity service, using the Nippita classification system. Average Annual Percentage Changes (AAPC) were calculated along with 95% confidence intervals and P values set at 0.05.

RESULTS

The overall rate of induction of labour increased from 21.3% in 2012 to 30.9% in 2017, representing an Average Annual Percent Change of 8.1, P<0.0001 (95% CI 7-9.6). The greatest AAPC was seen in group 5 (parous, no previous caesarean section, 39-40 weeks, single cephalic), followed by group 2 (nulliparous, 39-40 weeks, single cephalic) and 1 (nulliparous, 37-38 weeks, single cephalic).

CONCLUSIONS

The use of the Nippita classification system allowed for standardised comparison across timepoints, facilitating identification of the subpopulations driving changes in rates of induction of labour. Rates of induction of labour saw a year on year increase which in this maternity service, it is not being driven by post-dates pregnancies. Further work is required to understand the role of other potential contributors such as diabetes.

Turkish midwives' experiences and opinions in promoting normal births: A grounded theory study

INTRODUCTION

Worldwide, the biomedical model of maternity care has been dominant, with the overuse of interventions.

AIM

This study aimed to gain a deeper understanding of the experiences and opinions of Turkish midwives regarding the promotion of normal births.

METHODS

In-depth interviews were conducted with 12 midwives; data were analysed using grounded theory. The data were analysed according to the constant comparative method.

FINDINGS

The study generated a core category (We want to promote normal births, but have no power to do it), which means all participants wanted to promote normal births. However, they have been disempowered by the medicalised systems of care. There were also three main categories (different ideologies in the labour ward, the midwives have no power, unempowered women). The participants reported that different ideologies in the labour ward were a challenge to promoting normal births. Their working conditions and education level were not enough to support normal birth. The pregnant women were described as unempowered due to a lack of antenatal education and having a fear of childbirth.

CONCLUSION AND IMPLICATIONS FOR PRACTICE

Normal birth could be promoted by enhancing the power and responsibilities of midwives. The women need antenatal education to have a normal birth. The normal birth may promote the enhanced readiness of women and midwives.

The association of birth by caesarean section and cognitive outcomes in offspring: a systematic review

PURPOSE

Studies have reported children born by caesarean section are more likely to have lower cognitive outcomes compared to those born by vaginal delivery. This paper reviews the literature examining caesarean birth and offspring cognitive outcomes.

METHODS

A systematic search for observational studies or case-control studies that compared cognitive outcomes of people born by caesarean section with those born by vaginal delivery was conducted in six databases (Medline, PubMed, EMBASE, PsychInfo, CINAHL, Web of Science) from inception until December 2019 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were assessed for quality and a narrative synthesis was undertaken considering the evidence for a causal relationship according to the Bradford Hill Criteria.

RESULTS

A total of seven studies were identified. Of these, four found a significant association between elective and emergency caesarean birth and reduction in offspring cognitive performance as measured by school performance or validated cognitive testing. Three studies found no association. There was variability in the quality of the studies, assessment of the reason for caesarean section (emergency vs elective), measurement of outcomes and adjustment for confounding factors.

CONCLUSION

The evidence of an association between CS birth and lower offspring cognitive functioning is inconsistent. Based on currently available data, there is no evidence that a causal association exists. To better examine this association, future studies should (a) distinguish elective and emergency caesareans, (b) adequately adjust for confounding variables and (c) have valid outcome measures of cognition.

Association of Cesarean Delivery with Childhood Hospitalization for Infections Before 13 Years of Age

OBJECTIVES

To determine the association between cesarean delivery and childhood infections up to 13 years of age.

STUDY DESIGN

We conducted a longitudinal cohort study of 731 803 children born between 2006 and 2016 at all hospitals in the province of Quebec, Canada. We followed children born by cesarean, operative vaginal, and nonoperative vaginal delivery up to 13 years of age. Outcomes included hospitalization for otitis media, respiratory, infectious enteritis, and other infections. We estimated hazard ratios with 95% CIs for the association between mode of delivery and childhood infections, adjusted for patient characteristics.

RESULTS

At age 3-4 years, cesarean delivery was associated with a 1.07-fold greater risk of otitis media (95% CI, 1.03-1.11), a 1.15-fold greater risk of respiratory infection (95% CI, 1.09-1.22), and a 1.13-fold greater risk of infectious enteritis (95% CI, 1.03-1.25) compared with nonoperative vaginal delivery. However, operative vaginal delivery was associated with these same outcomes. Both cesarean and operative vaginal delivery were more strongly associated with infection hospitalization before age 1 year, but associations disappeared after 5 years.

CONCLUSIONS

Cesarean delivery is associated with infection hospitalization before but not after age 5 years. However, associations were also present for operative vaginal delivery, which suggests that mechanisms other than exposure to maternal vaginal flora explain the relationship.

The birthing brain: A lacuna in neuroscience

During pregnancy, maternal brain neuroplasticity indicates vast neurofunctional and neuroanatomical changes. Recent findings documented a similarly massive readjustment after pregnancy. Currently, these brain changes are interpreted as preparation for and adjustment of the maternal brain to motherhood. Yet, this perspective leaves many questions unsolved. Neuroscientific studies have not yet been conducted to determine the brain areas that function during natural childbirth even though physiological birth is the natural process of women who have reproduced successfully throughout two million years of evolution of the genus Homo. It is rational to believe that the female brain is an active and crucial actor during birth and that birth, itself, is a process that requires brain neuroplasticity. Lack of studies of the birthing brain and brain preparation for birth is a significant lacuna in neuroscience research. I demonstrate theoretically that a new hypothesis for complementary interpretation of maternal brain neuroplasticity is reasonable: Certain maternal brain changes during pregnancy can be interpreted asbrain preparation for birth and certain maternal brain changes after birth can be interpreted asbrain recovery after the tremendous event of birth. This essay can be a starting point for new directions in neuroscience studies.

A good start in life is important-perinatal factors dictate early microbiota development and longer term maturation

Maternal health status is vital for the development of the offspring of humans, including physiological health and psychological functions. The complex and diverse microbial ecosystem residing within humans contributes critically to these intergenerational impacts. Perinatal factors, including maternal nutrition, antibiotic use and maternal stress, alter the maternal gut microbiota during pregnancy, which can be transmitted to the offspring. In addition, gestational age at birth and mode of delivery are indicated frequently to modulate the acquisition and development of gut microbiota in early life. The early-life gut microbiota engages in a range of host biological processes, particularly immunity, cognitive neurodevelopment and metabolism. The perturbed early-life gut microbiota increases the risk for disease in early and later life, highlighting the importance of understanding relationships of perinatal factors with early-life microbial composition and functions. In this review, we present an overview of the crucial perinatal factors and summarise updated knowledge of early-life microbiota, as well as how the perinatal factors shape gut microbiota in short and long terms. We further discuss the clinical consequences of perturbations of early-life gut microbiota and potential therapeutic interventions with probiotics/live biotherapeutics.

Preventing Atopic Diseases During Childhood - Early Exposure Matters

Atopic diseases in childhood are a major burden worldwide and there is still a lack of knowledge about treatable causes. In industrialized countries such as Germany, almost every second child is sensitized to at least one common allergen. Recent studies show that although the predisposition to allergies is inherited, the adaptive immune system of neonates and infants follows a developmental trajectory and whether an allergy actually occurs depends also on timing of allergen exposure including diet as well as environmental factors. New recommendations are far from being rigid of allergen avoidance; it is rather moving toward conditions that stand for more biodiversity. The observation that introduction of peanuts or eggs early in life significantly reduced the development of a later allergy will change our recommendations for the introduction of complementary foods. This is consistent with the hygiene hypothesis that early provocation shapes the developing immune system so that it reacts appropriately. Therefore, promoting the development of tolerance is at the heart of sensible allergy prevention - and this begins with the last trimester of pregnancy. In light of this concept, actual recommendations are discussed.

Caesarean section and severe upper and lower respiratory tract infections during infancy: Evidence from two UK cohorts

BACKGROUND

Several studies have reported that birth by caesarean section is associated with increased risk of lower respiratory tract infections in the child, but it is unclear whether this applies to any caesarean section or specifically to planned caesareans. Furthermore, although infections of the upper respiratory tract are very common during childhood, there is a scarcity of studies examining whether caesarean is also a risk factor for this site of infection.

METHODS

We obtained data from two UK cohorts: the Millennium Cohort Study (MCS) and linked administrative datasets of the population of Wales through the Secure Anonymised Information Linkage (SAIL) databank. The study focused on term-born singleton infants and included 15,580 infants born 2000-2002 (MCS) and 392,145 infants born 2002-2016 (SAIL). We used information about mode of birth (vaginal delivery, assisted vaginal delivery, planned caesarean and emergency caesarean) from maternal report in the MCS and from hospital birth records in SAIL. Unplanned hospital admission for lower respiratory tract infection (LRTI) was ascertained from maternal report in the MCS and from hospital record ICD codes in SAIL. Information about admissions for upper respiratory tract infection (URTI) was available from SAIL only. Cox regression was used to estimate hazard ratios for each outcome and cohort separately while accounting for a wide range of confounders. Gestational age at birth was further examined as a potential added, indirect risk of planned caesarean birth due to the early delivery.

FINDINGS

The rate of hospital admission for LRTI was 4.6 per 100 child years in the MCS and 5.9 per 100 child years in SAIL. Emergency caesarean was not associated with LRTI admission during infancy in either cohort. In the MCS, planned caesarean was associated with a hazard ratio of 1.39 (95% CI 1.03, 1.87) which further increased to 1.65 (95% CI 1.24, 2.19) when gestational age was not adjusted for. In SAIL, the adjusted hazard ratio was 1.10 (95% CI 1.05, 1.15), which increased to 1.17 (95% CI 1.12, 1.22) when gestational age was not adjusted for. The rate of hospital admission for URTI was 5.9 per 100 child years in SAIL. Following adjustments, emergency caesarean was found to have a hazard ratio of 1.09 (95% CI 1.05, 1.14) for hospital admission for URTI. Planned caesarean was associated with a hazard ratio of 1.11 (95% CI 1.06, 1.16) which increased to 1.17 (95% CI 1.12, 1.22) when gestational age was not adjusted for.

CONCLUSIONS

The risk of severe LRTIs during infancy is moderately elevated in infants born by planned caesarean compared to those born vaginally. Infants born by any type of caesarean may also be at a small increased risk of severe URTIs. The estimated effect sizes are stronger if including the indirect effect arising from planning the caesarean birth for an earlier gestation than would have occurred spontaneously. Further studies are needed to confirm these results.

Differential access to continuity of midwifery care in Queensland, Australia

ObjectiveTo determine maternal access to continuity of midwifery care in public maternity hospitals across the state of Queensland, Australia. MethodsMaternal access to continuity of midwifery care in Queensland was modelled by considering the proportion of midwives publicly employed to provide continuity of midwifery care alongside 2017 birth data for Queensland Hospital and Health Services. The model assumed an average caseload per full-time equivalent midwife working in continuity of care with 35 women per annum, based on state Nursing and Midwifery Award conditions. Hospitals were grouped into five clusters using standard Australian hospital classifications. ResultsTwenty-seven facilities (out of 39, 69%) across all 15 hospital and health services in Queensland providing a maternity service offered continuity of midwifery care in 2017 (birthing onsite). Modelling applying the assumed caseload of 35 women per full-time equivalent midwife found wide variations in the percentage of women able to access continuity of midwifery care, with access available for an estimated 18% of childbearing women across the state. Hospital classifications with higher clinical services capability and birth volume did not equate with higher access to continuity of midwifery care in metropolitan areas. Regional health services with level 3 district hospitals assisting with &lt;500 births showed higher levels of access, potentially due to additional challenges to meet local population needs to those of a metropolitan service. Access to full continuity of midwifery care in level 3 remote hospitals (&lt;500 births) was artificially inflated due to planned pre-labour transfers for women requiring specialised intrapartum care and women who planned to birth at other hospitals. ConclusionsDespite strong evidence that continuity of midwifery care offers optimal care for women and their babies, there was significant variation in implementation and scale-up of these models across hospital jurisdictions. What is known about the topic?Access to continuity of midwifery care for pregnant women within the public health system varies widely; however, access variation among different hospital classification groups in Australian states and territories has not been systematically mapped. What does this paper add?This paper identified differential access to continuity of midwifery care among hospital classifications grouped for clinical services capability and birth volume in one state, Queensland. It shows that higher clinical services capability and birth volume did not equate with higher access to continuity of midwifery care in metropolitan areas. What are the implications for practitionersScaling up continuity of midwifery care among all hospital classification groups in Queensland remains an important public health strategy to address equitable service access.

Disruption of physiological labour; - A population register-based study among nulliparous women at term

OBJECTIVES

Current labour practices have seen an acceleration in interventions to either initiate, monitor, accelerate, or terminate the physiological process of pregnancy and childbirth. This study aimed to describe and analyse the use of interventions in childbirth in Denmark over almost two decades (2000-2017). We also examined the extent to which contemporary care adheres to current international recommendations towards restricted use of interventions.

STUDY DESIGN

A national retrospective Danish register-based cohort study including all nulliparous women with term births with singleton pregnancy and a foetus in cephalic between the years 2000 and 2017 (n = 380,326 births). Multivariate regression analyses with adjustment for change in population were performed.

MAIN OUTCOME MEASURES

Induction of labour, epidural analgesia, and augmentation of labour.

RESULTS

Between 2000/2001 and 2016/2017, the prevalence increased for induction of labour from 5.1% to 22.8%, AOR 4.84, 95% CI [4.61-5.10], epidural analgesia from 10.5% to 34.3% (AOR 4.10, 95% CI [3.95-4.26]), and augmentation of labour decreased slightly from 40.1% to 39.3% (AOR 0.84, 95% CI [0.81-0.86]). Having more than one of the three mentioned interventions increased from 12.8% in to 30.9%.

CONCLUSIONS

The number of interventions increased during the study period as well as the number of interventions in each woman. As interventions may interfere in physiological labour and carry the risk of potential short- and long-term consequences, the findings call for a careful re-evaluation of contemporary maternity care with a "first, do no harm" perspective.

Pediatrics Consequences of Caesarean Section-A Systematic Review and Meta-Analysis

BACKGROUND

Cesarean section is a surgical procedure, which is the most frequently performed in gynecology and obstetrics. It is commonly believed that an operative delivery is a less painful and safer mode of delivery, which translates into an increasing number of the procedures performed without medical indications. The maternal sequelae of cesarean sections are well elucidated and widely discussed in the literature, while long-term neonatal consequences still remain the issue of research and scientific dispute. The aim of the present paper was to perform a systematic review of current literature regarding pediatrics consequences of cesarean section.

METHODS

We reviewed available data from PubMed, Science Direct as well as Google Scholar bases concerning early and long-term neonatal sequelae of operative deliveries. The following key words were used: "cesarean section", "caesarean section", "neonatal outcomes", "respiratory disorders", "asthma", "obesity", "overweight", and "neurological disorders". A total of 1636 papers were retrieved out of which 27 were selected for the final systematic review whereas 16 articles provided data for meta-analysis. Statistical analyses were performed using RevMan 5.4. To determine the strength of association between the caesarean section and respiratory tract infections, asthma, diabetes type 1 as well as obesity the pooled odds ratios (OR) with the 95% confidence intervals (CI) were calculated.

RESULTS

Conducted meta-analyses revealed that caesarean section is a risk factor for respiratory tract infections (pooled OR = 1.30 95%CI 1.06-1.60, p = 0.001), asthma (pooled OR = 1.23 95%CI 1.14-1.33, p < 0.00001) as well as obesity (pooled OR = 1.35 95%CI 1.29-1.41, p < 0.00001) in offspring.

CONCLUSIONS

The results of the studies included indicated that children delivered by cesarean section more commonly developed respiratory tract infections, obesity and the manifestations of asthma than children delivered vaginally. The risk of developing diabetes mellitus type 1 or neurological disorders in offspring after caesarean section is still under discussion.

Intrapartum zigzag pattern of fetal heart rate is an early sign of fetal hypoxia: A large obstetric retrospective cohort study

Introduction

The aim of the present study was to identify possible associations of fetal heart rate (FHR) patterns during the last 2 hours of labor with fetal asphyxia expressed by umbilical artery acidemia at birth and with neonatal complications in a large obstetric cohort.

Material and methods

Cardiotocographic recordings from 4988 singleton term childbirths over 1 year were evaluated retrospectively and blinded to the pregnancy and neonatal outcomes in a university teaching hospital in Helsinki, Finland. Umbilical artery pH, base excess and pO₂, low Apgar scores at 5 minutes, need for intubation and resuscitation, early neonatal hypoglycemia, and neonatal encephalopathy were used as outcome variables. According to the severity of the neonatal complications at birth, the cohort was divided into three groups: no complications (Group 1), moderate complications (Group 2) and severe complications (Group 3).

Results

Of the 4988 deliveries, the ZigZag pattern (FHR baseline amplitude changes of >25 bpm with a duration of 2‐30 minutes) occurred in 11.7%, late decelerations in 41.0%, bradycardia episodes in 52.9%, reduced variability in 36.7%, tachycardia episodes in 13.9% and uterine tachysystole in 4.6%. No case of saltatory pattern (baseline amplitude changes of >25 bpm with a duration of >30 minutes) was observed. The presence of the ZigZag pattern or late decelerations, or both, was associated with cord blood acidemia (odds ratio [OR] 3.3, 95% confidence interval [CI] 2.3‐4.7) and severe neonatal complications (Group 3) (OR 3.3, 95% CI 2.4‐4.9). In contrast, no significant associations existed between the other FHR patterns and severe neonatal complications. ZigZag pattern preceded late decelerations in 88.7% of the cases. A normal FHR preceded the ZigZag pattern in 90.4% of the cases, whereas after ZigZag episodes, a normal FHR pattern was observed in only 0.9%.

Conclusions

ZigZag pattern and late decelerations during the last 2 hours of labor are significantly associated with cord blood acidemia at birth and neonatal complications. The ZigZag pattern precedes late decelerations, and the fact that normal FHR pattern precedes the ZigZag pattern in the majority of the cases suggests that the ZigZag pattern is an early sign of fetal hypoxia, which emphasizes its clinical importance.

Birth models of care and intervention rates: The impact of birth centres

Birth centres offer a midwifery-led model of care which supports a non-medicalised approach to childbirth. They are often reported as having low rates of birth intervention, however the precise impact is obscured because less disadvantaged mothers with less complex pregnancies, and who prefer and often select little intervention, are more likely to choose a birth centre. In this paper, we use a methodology that purges the impact of these selection effects and provides a causal interpretation of the impact of birth centres on intervention outcomes. Using administrative birth data on over 364,000 births in Australia's most populous state between 2001 and 2012, we implement an instrumental variables framework to address confounding factors influencing choice of birth setting. We find that giving birth in a birth centre results in significantly lower probabilities of intervention, and that critically, this impact has been increasing over time. Our estimates are larger than those in existing studies, reflecting our newer data, diverging intervention rates across birth settings, and our accounting for important selection effects. The results emphasise the greater role of birth centres in delivering on policy priorities which include greater maternal autonomy, lower intervention rates, and lower health system costs.

Cost of maternity care to public hospitals: a first 1000-days perspective from Queensland

Objective This study sought to compare costs for women giving birth in different public hospital services across Queensland and their babies. Methods A whole-of-population linked administrative dataset was used containing all health service use in a public hospital in Queensland for women who gave birth between 1 July 2012 and 30 June 2015 and their babies. Generalised linear models were used to compare costs over the first 1000 days between hospital and health services. Results The mean unadjusted cost for each woman and her baby (n = 134910) was A$17406 in the first 1000 days. After adjusting for clinical and demographic factors and birth type, women and their babies who birthed in the Cairns Hospital and Health Service (HHS) had costs 19% lower than those who birthed in Gold Coast HHS (95% confidence interval (CI) -32%, -4%); women and their babies who birthed at the Mater public hospitals had costs 28% higher than those who birthed at Gold Coast HHS (95% CI 8, 51). Conclusions There was considerable variation in costs between hospital and health services in Queensland for the costs of delivering maternity care. Cost needs to be considered as an important additional element of monitoring programs. What is known about the topic? The Australian maternal care system delivers high-quality, safe care to Australian mothers. However, this comes at a considerable financial cost to the Australian public health system. It is known that there are variations in the cost of care depending upon the model of care a woman receives, and the type of delivery she has, with higher-cost treatment not necessarily being safer or producing better outcomes. What does this paper add? This paper compares the cost of delivering a full cycle of maternity care to a woman at different HHSs across Queensland. It demonstrates that there is considerable variation in cost across HHSs, even after adjusting for clinical and demographic factors. What are the implications for practitioners? Reporting of cost should be an ongoing part of performance monitoring in public hospital maternity care alongside clinical outcomes to ensure the sustainability of the high-quality maternal health care Australian public hospitals deliver.

Mild neonatal complications following guideline-compliant vacuum-assisted delivery in Japan: improvements still needed

INTRODUCTION

Neonatal cephalohematoma and hyperbilirubinemia are often encountered after vacuum-assisted delivery. For safe obstetric practice, guidelines for vacuum procedure were published in 2014 in Japan. We aimed to identify the risk of mild neonatal complications since guideline introduction.

METHODS

This retrospective observational study included singleton deliveries at term gestation from 2015 to 2019 at a single perinatal center in Japan. Incidences of neonatal jaundice requiring phototherapy, cephalohematoma, and umbilical artery pH <7.10 were determined and risk factors relevant to the development of hyperbilirubinemia were evaluated.

RESULTS

Of 1010 deliveries during the study period, vacuum procedures were attempted in 183 (18%). Guideline recommendations were fully adhered to in over 98% of vacuum procedures. Phototherapy for neonatal hyperbilirubinemia was performed in 75 (41%) of 183 deliveries with vacuum procedure, cephalohematoma occurred in 35 (19%), and umbilical artery pH <7.10 was observed in 10 (5.5%), all of which were significantly higher than without vacuum procedure, such as hyperbilirubinemia (11%, risk ratio [RR] = 3.8, 95% confidence interval [CI] = 2.9 - 4.9, p < .0001), cephalohematoma (1.0%, RR = 19.8, 95%CI = 9.3 - 41.9, p < .0001), and umbilical artery pH <7.10 (0.6%, RR = 9.0, 95%CI = 3.1 - 26.1, p < .0001). Multiple logistic regression analysis demonstrated that vacuum procedure was the factor most strongly associated with neonatal hyperbilirubinemia (odds ratio = 3.5, 95%CI = 2.2 - 5.5, p < .0001).

DISCUSSION

Vacuum procedure is an important option for the safe vaginal delivery. However, neonates should be observed for development of jaundice to prevent kernicterus even after optimally performed vacuum-assisted delivery.

Understanding childbirth as a complex salutogenic phenomenon: The EU COST BIRTH Action Special Collection

In 2014, the EU funded a four-year European Cooperation in Science and Technology (COST) Action to address the topic of childbirth. The COST Birth Action was a cross-European network, that brought together over 120 scientists, practitioners, activists and policy makers from 34 countries to work on intrapartum care. The central aim was to advance the state of research and practice in a specific area of great clinical and social importance, intrapartum care. The Action used inter and trans-disciplinary approaches to address birth from multiple perspectives and drew on complexity theory and the concept of salutogenesis (wellbeing). This special collection presents six papers produced from the Action and gives a sense of the range and depth of the work conducted. The Collection illustrates the knowledge that can be generated when a diverse group of people come together with a similar goals and perspectives.

Tipo de parto y sensibilidad materna: Efectos en el desarrollo socioemocional de niños y niñas al año de edad

La infancia temprana es un periodo de gran relevancia en el desarrollo socioemocional infantil; de hecho, es donde se sientan las bases del desarrollo futuro. En este sentido, las adquisiciones durante el primer año de vida son predictores importantes de las habilidades sociales y emocionales futuras, de modo que la sensibilidad materna, según evidencia respecto a sus efectos en el desarrollo socioemocional del niño, ha demostrado ser un aspecto fundamental durante este periodo. Teniendo esto en cuenta, y considerando la relevancia de dicha competencia, así como el alza mundial y nacional en las tasas de cesárea y los posibles riesgos asociados al tipo de parto vivenciado, el presente estudio tuvo como objetivo analizar la influencia dela sensibilidad materna y del tipo de parto en el desarrollo socioemocional infantil al año de edad. Para ello, se estudió una muestra no probabilística intencionada de 91 madres con sus respectivos hijos o hijas de distinto nivel socioeconómico que asistían a salas cuna públicas o privadas en la ciudad de Santiago, Chile, por medio de dos instrumentos: la escala de sensibilidad del adulto (ESA) y la functional emotional assessment scale (FEAS). En general, los resultados no mostraron diferencias en el desarrollo socioemocional de los niños según el tipo de parto, aunque sí se pudo apreciar una relación entre una mayor sensibilidad materna y un mayor desarrollo socioemocional de los niños al año de edad. Al final se discuten las implicaciones de promover la sensibilidad materna con el fin de apoyar un óptimo desarrollo socioemocional en los infantes.

Maternal bacteria to correct abnormal gut microbiota in babies born by C-section

INTRODUCTION

There is evidence that caesarean section (CS) is associated with increased risk of childhood obesity, asthma, and coeliac disease. The gut microbiota of CS-born babies differs to those born vaginally, possibly due to reduced exposure to maternal vaginal bacteria during birth. Vaginal seeding is a currently unproven practice intended to reduce such differences, so that the gut microbiota of CS-born babies is similar to that of babies born vaginally. Our pilot study, which uses oral administration as a novel form of vaginal seeding, will assess the degree of maternal strain transfer and overall efficacy of the procedure for establishing normal gut microbiota development.

METHODS AND ANALYSIS

Protocol for a single-blinded, randomized, placebo-controlled pilot study of a previously untested method of vaginal seeding (oral administration) in 30 CS-born babies. A sample of maternal vaginal bacteria is obtained prior to CS, and mixed with 5 ml sterile water to obtain a supernatant. Healthy babies are randomized at 1:1 to receive active treatment (3 ml supernatant) or placebo (3 ml sterile water). A reference group of 15 non-randomized vaginal-born babies are also being recruited. Babies' stool samples will undergo whole metagenomic shotgun sequencing to identify potential differences in community structure between CS babies receiving active treatment compared to those receiving placebo at age 1 month (primary outcome). Secondary outcomes include differences in overall gut community between CS groups (24 hours, 3 months); similarity of CS-seeded and placebo gut profiles to vaginally-born babies (24 hours, 1 and 3 months); degree of maternal vaginal strain transfer in CS-born babies (24 hours, 1 and 3 months); anthropometry (1 and 3 months) and body composition (3 months).

ETHICS AND DISSEMINATION

Ethics approval by the Northern A Health and Disability Ethics Committee (18/NTA/49). Results will be published in peer-reviewed journals and presented at international conferences.

Birthing Consciousness as a Case of Adaptive Altered State of Consciousness Associated With Transient Hypofrontality

In this article, I present the concept of “birthing consciousness,” a psychophysical altered state of women that can occur during natural and undisturbed birth. I demonstrate that this altered state of consciousness (ASC) has phenomenological and cognitive features of hypofrontality; thus, birthing consciousness probably shares a similar brain mechanism to that postulated by the transient-hypofrontality theory (THT). I argue that until recently (with the advent of modern medical intervention), in evolutionary terms, women lacking the proclivity for this specific brain mechanism had a lower chance of reproducing successfully. Hence, I suggest a general and preliminary hypothesis concerning THT: Birthing consciousness is one example of an adaptive pain-induced ASC associated with transient hypofrontality.
