Abstract
The intrapartum period is a crucial time in the continuum of pregnancy and parenting. Events during this time are shaped by individuals' unique sociocultural and health characteristics and by their healthcare providers, practice protocols, and the physical environment in which care is delivered. Childbearing people in the United States have less opportunity for midwifery care than in other high-income countries. In the United States, there are 4 midwives for every 1000 live births, whereas, in most other high-income countries, there are between 30 and 70 midwives. Furthermore, these countries have lower maternal and neonatal mortality rates and have consistently lower costs of care. National and international evidences consistently report that births attended by midwives have fewer interventions, cesarean deliveries, preterm births, inductions of labor, and more vaginal births after cesarean delivery. In addition, midwifery care is consistently associated with respectful care and high patient satisfaction. Midwife-physician collaboration exists along a continuum, including births attended independently by midwives, births managed in consultation with a physician, and births attended primarily by a physician with a midwife acting as consultant on the normal aspects of care. This expert review defined midwifery care and provided an overview of midwifery in the United States with an emphasis on the intrapartum setting. Health outcomes associated with midwifery care, specific models of intrapartum care, and workforce issues have been presented within national and international contexts. Recommendations that align with the integration of midwifery have been suggested to improve national outcomes and reduce pregnancy-related disparities.

Abstract
Objective To examine how physical and psychological childbirth experiences affect maternal perceptions and experiences of early infant behavioural style (temperament). Background Unnecessary interventions may disturb the normal progression of physiological childbirth and instinctive neonatal behaviours that facilitate mother-infant bonding and breastfeeding. While little is known about how a medicalised birth may influence developing infant temperament, high impact interventions which affect neonatal crying and cortisol levels could have longer term consequences for infant behaviour and functioning. Methods A retrospective Internet survey was designed to fully explore maternal experiences of childbirth and her postnatal perceptions of infant behaviour. Data collected from 999 mother-infant dyads were analysed using Pearson's correlations and multiple analyses of covariance, employing the Bonferroni method of correction to establish initially significant variables. Multiple linear regressions were conducted to determine major perinatal contributors to perceived early infant temperament. Results Multiple regression analyses on each of the eight Mother and Baby Scales outcome variables indicated that early infant behavioural style (0-6 months) was largely predicted by subjective maternal states during and post-childbirth, postnatal depression scores, maternal personality traits and infant age. For example, infant age (Beta = 0.440, p = 0.000) was the most significant predictor of Alert-Responsive infant behaviour, followed by maternal Postnatal Positive experience (Beta = 0.181, p = 0.000). In contrast, depression (EPDS) scores (Beta = 0.370, p = 0.000) were the most significant predictor of Unsettled-Irregular infant behaviour, followed by Anxious-Afraid Birth Emotions (Beta = 0.171, p = 0.000) and infant age (Beta = -0.196, p = 0.000). Mothers also perceived their infants as more Alert-Responsive (Beta = 0.080, p = 0.010) and Easier overall (Beta = 0.085, p = 0.008) after a Supported birth experience. Conclusion Maternal and infant outcomes were influenced by multiple physical and psychological perinatal variables. The mother's subjective experience appeared to be of equal significance to more objective factors (e.g. birthplace/mode). Social support enhanced the mother's childbirth experience, benefitting her perceptions of her baby's early temperament. These findings provide further support for current World Health Organisation intrapartum guidelines (2018) on the importance of making childbirth a 'positive experience' for women.

Health Care Providers' Perceptions of Quality of Childbirth and Its Associated Risks in Poland. J Obstet Gynecol Neonatal Nurs 2021; 50:464-474. [PMID: 33991489 DOI: 10.1016/j.jogn.2021.04.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/01/2021] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE To describe Polish maternity care providers' cognitive frames of quality of childbirth and how they relate to providers' perceptions of childbirth using Baranowska's model of quality of care. DESIGN Mixed-methods, cross-sectional. SETTING Twenty-four hospitals and outpatient clinics that provide maternity care located in two central districts of Poland. PARTICIPANTS Obstetricians or resident physicians in obstetrics (n = 50) and midwives (n = 676) who were actively engaged in the provision of maternity care. METHODS Participants completed a survey that included two tasks. The first was a sentence completion technique that we used as a projective method to investigate participants' preconceived attitudes about quality of childbirth. Depending on the number of perspectives (as in Baranowska's model) included in the statements, participants' perceptions were categorized as strongly narrowed (zero perspectives), narrow (one perspective), intermediate (two perspectives), or holistic (three perspectives). In the second task, we asked participants to choose one statement out of three that best represented their beliefs about childbirth. RESULTS Participants had mostly intermediate (n = 436, 60%) or narrow (n = 183, 25%) perceptions of quality of childbirth. Those with less work experience tended to have more encompassing perspectives. More than half of the participants perceived childbirth as a physiologic process requiring no medical interventions (n = 385, 53%). Only 9% (n = 65) of the participants reported that childbirth is always associated with great risk. There was a main effect of work experience on the number of perspectives included in the definition of quality of childbirth with F(2, 720) = 5.532, p = .004. Participants with less work experience included more perspectives in their statements. There were no statistically significant differences in the perception of quality of childbirth between obstetricians and midwives, with F(1, 724) = .000, p = 0.991, or between participants from different workplaces, with F(3, 719) = 1.742, p = .157. CONCLUSION Only a small share of participants had holistic perceptions of quality of childbirth consistent with Baranowska's model. This may not only contribute to the medicalization of maternity care in Poland, but it also contrasts with participants' declarations that childbirth is a physiologic process with no need for medical interventions. Considering the greater rates of medical interventions in maternity care in Poland, the latter finding requires further research.

Abstract
In Brazil, the excess of interventions that anticipate childbirth, such as cesarean sections and labor inductions, has resulted in the shortening of pregnancy, with negative consequences on maternal-infant outcomes. This commentary presents a novel way to measure gestational age: the continuous variable "Potential pregnancy days lost." Using data from the Live Birth Information System (SINASC), we counted the missing days between the period until childbirth and the average duration of pregnancy (280 days), or the lost weeks. This measure can be used as an outcome variable (socioeconomic-demographic characteristics of the mother, type of childbirth, financing, etc.) or exposure variable (for neonatal, infant, and maternal outcomes). The indicator can be used in municipal and national cohorts and intervention studies to analyze hospitals and regions. We discuss the limits and scope of gestational age measures and, given their inaccuracies, the importance of studying their trends.

PLoS Med 2019; 16:e1002996.

Abstract
BACKGROUND Previous studies have suggested that cesarean section (CS) is associated with offspring overweight and obesity. However, few studies have been able to differentiate between elective and nonelective CS, which may differ in their maternal risk profile and biological pathway. Therefore, we aimed to examine the association between differentiated forms of delivery with CS and risk of obesity in young adulthood. METHODS AND FINDINGS Using Swedish population registers, a cohort of 97,291 males born between 1982 and 1987 were followed from birth until conscription (median 18 years of age) if they conscripted before 2006. At conscription, weight and height were measured and transformed to World Health Organization categories of body mass index (BMI). Maternal and infant data were obtained from the Medical Birth Register. Associations were evaluated using multinomial and linear regressions. Furthermore, a series of sensitivity analyses were conducted, including fixed-effects regressions to account for confounders shared between full brothers. The mothers of the conscripts were on average 28.5 (standard deviation 4.9) years old at delivery and had a prepregnancy BMI of 21.9 (standard deviation 3.0), and 41.5% of the conscripts had at least one parent with university-level education. Out of the 97,291 conscripts we observed, 4.9% were obese (BMI ≥ 30) at conscription. The prevalence of obesity varied slightly between vaginal delivery, elective CS, and nonelective CS (4.9%, 5.5%, and 5.6%, respectively), whereas BMI seemed to be consistent across modes of delivery. We found no evidence of an association between nonelective or elective CS and young adulthood obesity (relative risk ratio 0.96, confidence interval 95% 0.83-1.10, p = 0.532 and relative risk ratio 1.02, confidence interval 95% 0.88-1.18, p = 0.826, respectively) as compared with vaginal delivery after accounting for prepregnancy maternal BMI, maternal diabetes at delivery, maternal hypertension at delivery, maternal smoking, parity, parental education, maternal age at delivery, gestational age, birth weight standardized according to gestational age, and preeclampsia. We found no evidence of an association between any form of CS and overweight (BMI ≥ 25) as compared with vaginal delivery. Sibling analysis and several sensitivity analyses did not alter our findings. The main limitations of our study were that not all conscripts had available measures of anthropometry and/or important confounders (42% retained) and that our cohort only included a male population. CONCLUSIONS We found no evidence of an association between elective or nonelective CS and young adulthood obesity in young male conscripts when accounting for maternal and prenatal factors. This suggests that there is no clinically relevant association between CS and the development of obesity. Further large-scale studies are warranted to examine the association between differentiated forms of CS and obesity in young adult offspring.

Abstract
The vertical transmission of microbes from mother to offspring is critical to the survival, development, and health of animals. Invertebrate systems offer unique opportunities to conduct studies on microbiome-development-reproduction dynamics since reproductive modes ranging from oviparity to multiple types of viviparity are found in these animals. One such invertebrate is the live-bearing cockroach, Diploptera punctata. Females carry embryos in their brood sac, which acts as the functional equivalent of the uterus and placenta. In our study, 16S rRNA sequencing was used to characterize maternal and embryonic microbiomes as well as the development of the whole-body microbiome across nymphal development. We identified 50 phyla and 121 classes overall and found that mothers and their developing embryos had significantly different microbial communities. Of particular interest is the notable lack of diversity in the embryonic microbiome, which is comprised exclusively of Blattabacteria, indicating microbial transmission of only this symbiont during gestation. Our analysis of postnatal development reveals that significant amounts of non-Blattabacteria species are not able to colonize newborn D. punctata until melanization, after which the microbial community rapidly and dynamically diversifies. While the role of these microbes during development has not been characterized, Blattabacteria must serve a critical role providing specific micronutrients lacking in milk secretions to the embryos during gestation. This research provides insight into the microbiome development, specifically with relation to viviparity, provisioning of milk-like secretions, and mother-offspring interactions during pregnancy.

Abstract
Mother-child cohort studies have established that both pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) are independently associated with cardio-metabolic risk factors in juvenile and adult offspring, including systolic and diastolic blood pressure. In rodent studies maternal obesity confers many facets of the metabolic syndrome including a persistent sympathy-excitatory hyperresponsiveness and hypertension acquired in the early stages of development. Insight from these animal models raises the possibility that early life exposure to the nutritional and hormonal environment of obesity in pregnancy in humans may lead to early onset of metabolic syndrome and/or essential hypertension. This chapter will address the development of rodent models of maternal overnutrition and obesity, which have proved invaluable in generating testable hypotheses for clinical translation and the development of intervention strategies to stem the swelling tide of obesity and its comorbidities predicted for future generations.

Abstract
We determined the effect of short-chain galacto-oligosaccharides (scGOS), long-chain fructo-oligosaccharides (lcFOS) and Bifidobacterium breve M-16V on the gut microbiota of cesarean-born infants. Infants were randomized to receive a standard formula (control), the same with scGOS/lcFOS and B. breve M-16V (synbiotic), or with scGOS/lcFOS (prebiotic) from birth until week 16, 30 subjects born vaginally were included as a reference group. Synbiotic supplementation resulted in a higher bifidobacteria proportion from day 3/5 (P < 0.0001) until week 8 (P = 0.041), a reduction of Enterobacteriaceae from day 3/5 (P = 0.002) till week 12 (P = 0.016) compared to controls. This was accompanied with a lower fecal pH and higher acetate. In the synbiotic group, B. breve M-16V was detected 6 weeks postintervention in 38.7% of the infants. This synbiotic concept supported the early modulation of Bifidobacterium in C-section born infants that was associated with the emulation of the gut physiological environment observed in vaginally delivered infants.
