Early brain microstructural development among preterm infants requiring caesarean section versus those delivered vaginally. Sci Rep 2023; 13:21514.

Abstract
It is known that the rate of caesarean section (C-section) has been increasing among preterm births. However, the relationship between C-section and long-term neurological outcomes is unclear. In this study, we utilized diffusion tensor imaging (DTI) to characterize the association of delivery method with brain white matter (WM) microstructural integrity in preterm infants. We retrospectively analyzed the DTI scans and health records of preterm infants without neuroimaging abnormality on pre-discharge term-equivalent MRI. We applied both voxel-wise and tract-based analyses to evaluate the association between delivery method and DTI metrics across WM tracts while controlling for numerous covariates. We included 68 preterm infants in this study (23 delivered vaginally, 45 delivered via C-section). Voxel-wise and tract-based analyses revealed significantly lower fractional anisotropy values and significantly higher diffusivity values across major WM tracts in preterm infants delivered via C-section when compared to those delivered vaginally. These results may be partially, but not entirely, mediated by lower birth weight among infants delivered by C-section. Nevertheless, these infants may be at risk for delayed neurodevelopment and could benefit from close neurological follow up for early intervention and mitigation of adverse long-term outcomes.

Abstract
OBJECTIVE To describe cerebral abnormalities and their risk factors in a contemporary cohort of infants born extremely premature after the introduction of routine cerebral magnetic resonance imaging (cMRI) at term-equivalent age. STUDY DESIGN All cMRI examinations performed during November 2017 and November 2020, based on a standardized neonatal cMRI protocol, were included into analysis. Pathologies were retrospectively classified into 3 categories: intraventricular hemorrhage (IVH), white matter disease, and cerebellar injuries. RESULTS A total of 198 cMRI examinations were available for analyses; 93 (47%) showed abnormalities, most frequently IVH (n = 65, 33%), followed by cerebellar injuries (n = 41, 21%), and white matter disease (n = 28, 14%). Severe abnormalities were found in 18% of patients (n = 36). Significant clinical risk factors for abnormalities on cMRI were lower Apgar scores, lower umbilical artery and first neonatal pH, asphyxia, blood culture-proven sepsis (especially late-onset), and prolonged need of respiratory support and supplemental oxygen. CONCLUSIONS After routine cMRI, without preconfirmed pathology by cranial ultrasonography, low-grade IVH, noncystic white matter disease, and cerebellar injuries were the most frequently found abnormalities. The clinical value and long-term benefit of the detection of these low-grade pathologies have yet to be confirmed.

Complex Perinatal Syndromes Affecting Early Human Growth and Development: Issues to Consider to Understand Their Aetiology and Postnatal Effects. Front Neurosci 2022; 16:856886. [PMID: 35509448 PMCID: PMC9058100 DOI: 10.3389/fnins.2022.856886] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 03/11/2022] [Indexed: 12/17/2022] Open
Abstract
Complex perinatal syndromes (CPS) affecting pregnancy and childhood, such as preterm birth, and intra- and extra-uterine growth restriction, have multiple, diverse contexts of complexity and interaction that determine the short- and long-term growth, health and development of all human beings. Early in life, genetically-guided somatic and cerebral development occurs alongside a psychism "in statu nascendi," with the neural structures subjected to the effects of the intra- and extra-uterine environments in preparation for optimal postnatal functioning. Different trajectories of fetal cranial and abdominal growth have been identified before 25 weeks' gestation, tracking differential growth and neurodevelopment at 2 years of age. Similarly, critical time-windows exist in the first 5-8 months of postnatal life because of interactions between the newborn and their environment, mother/care-givers and feeding practices. Understanding these complex relational processes requires abandoning classical, linear and mechanistic interpretations that are placed in rigid, artificial biological silos. Instead, we need to conduct longitudinal, interdisciplinary research and integrate the resulting new knowledge into clinical practice. An ecological-systemic approach is required to understand early human growth and development, based on a dynamic multidimensional process from the molecular or genomic level to the socio-economic-environmental context. For this, we need theoretical and methodological tools that permit a global understanding of CPS, delineating temporal trajectories and their conditioning factors, updated by the incorporation of new scientific discoveries. The potential to optimize human growth and development across chronological age and geographical locations - by implementing interventions or "treatments" during periods of greatest instability or vulnerability - should be recognized. Hence, it is imperative to take a holistic view of reproductive and perinatal issues, acknowledging at all levels the complexity and interactions of CPS and their sensitive periods, laying the foundations for further improvements in growth and development of populations, to maximize global human potential. We discuss here conceptual issues that should be considered for the development and implementation of such a strategy aimed at addressing the perinatal health problems of the new millenium.

Abstract
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.

Abstract
OBJECTIVE This study aimed to report maternal outcomes of preterm (<34 weeks of gestation) cesarean delivery. DATA SOURCES Medline, Embase, and ClinicalTrials.gov databases were searched electronically on September 1, 2020, utilizing combinations of the relevant medical subject heading terms, key words, and word variants for "cesarean delivery" and "outcome." STUDY ELIGIBILITY CRITERIA We included only studies reporting maternal outcomes of cesarean delivery performed at <34 weeks of gestation. STUDY APPRAISAL AND SYNTHESIS METHODS The primary outcome was a composite score of maternal surgical morbidity including maternal death, severe intrasurgical or postpartum hemorrhage, hysterectomy, need for blood transfusion, and damage to adjacent organs. Secondary outcomes were individual components of the primary outcome, need for reoperation, postsurgical infection, thromboembolism, and hysterectomy. We also performed 2 subgroup analyses considering cesarean delivery performed at <28 and <26 weeks of gestation. Meta-analyses of proportions using random effects model were used to combine data. RESULTS A total of 15 studies involving 8378 women undergoing cesarean delivery at <34 weeks of gestation were included in the systematic review. Composite adverse maternal outcome was reported in 16.2% of women (95% confidence interval, 15.4-17.0) undergoing a cesarean delivery before 34 weeks of gestation. Hemorrhage, either intra- or postoperative, was observed in 6.9% of cases (95% confidence interval, 6.4-7.5), whereas 6.3% (95% confidence interval, 4.2-8.7) required blood transfusion. Damage to adjacent organs complicated the primary surgery in 2.0% of women (95% confidence interval, 0.1-6.4), whereas 1.2% (95% confidence interval, 0.3-3.4) required a reoperation after cesarean delivery. Maternal death occurred in 0.1% (95% confidence interval, 0.0-1.4). In women undergoing cesarean delivery at <28 weeks of gestation, composite adverse maternal outcome complicated 22.9% of cases (95% confidence interval, 16.7-33.8) and 14.0% (95% confidence interval, 5.8-24.9) experienced hemorrhage whereas 7.7% (95% confidence interval, 4.4-11.8) required blood transfusion. Finally, when considering women undergoing cesarean delivery at <26 weeks of gestation, composite adverse maternal outcome was reported in 24.8% (95% confidence interval, 10.1-43.4), whereas the corresponding figures for hemorrhage and need for blood transfusion were 9.2% (95% confidence interval, 1.7-21.6) and 6.1% (95% confidence interval, 0.3-10.0), respectively. CONCLUSION Early cesarean delivery is affected by a high rate of maternal intra- and postoperative complications. The findings from systematic review can help clinicians in counseling parents when cesarean delivery is required in an early gestational age.

Abstract
Introduction Evidence is lacking regarding the benefit of caesarean section (CS) for long-term neurodevelopmental outcomes in singleton preterm neonates. Therefore, uncertainty remains regarding obstetrical best practice in the delivery of premature neonates. Objective Our objective was to determine the association between the mode of delivery and neurodevelopmental outcomes in preterm singleton neonates who were delivered by vaginal route (VR), CS with labour (CS-L), or CS without labour (CS-NL). Methods Singleton neonates of less than 29 weeks' gestation born January 1995 through December 2010 and admitted to our NICU and then assessed at neonatal follow-up clinic were studied. The primary outcome was neurodevelopmental impairment (NDI) defined as cerebral palsy, cognitive delay, major or minor visual impairment, or hearing impairment or deafness at 36 months' corrected age. Results In this retrospective cohort study of 1,452 neonates, 1,000 were eligible for the study and 881 (88.1%) were available for follow-up. There was no significant difference in mortality between VR group, CS-L group, and CS-NL group. At 3 years, there was no significant difference between the three groups in terms of NDI. The odds of composite outcome of mortality or NDI for neonates born via CS-NL versus VR, and CS-L versus VR were 0.90 (95% confidence interval [CI]: 0.59 to 1.37) and 1.08 (95% CI: 0.72 to 1.61), respectively. Propensity score-based matched-pair analyses did not show a significant association between the composite outcome and CS with or without labour. Conclusions CS was not associated with increased survival or decreased risk of NDI in premature singleton neonates born at less than 29 weeks' gestation.

Abstract
INTRODUCTION Worldwide cesarean birth had increased over the past three decades and in the USA, the overall rate of cesarean birth has increased from 23.8% in 1989 to 31.9% in 2018. Moreover, the substantial increase of preterm infants delivered by cesarean section had reached anywhere from 45% to 72% for gestational age <33 weeks. There is a considerable debate on whether cesarean section confers a survival advantage for preterm infants. Published data on the relationship between mode of delivery and survival rate were inconsistent and there is a lack of large randomized controlled trials (RCTs) that have investigated this important clinical concern. Thus, the aim of this study is to evaluate the impact of cesarean section on the survival rate of very low birth weight (VLBW) infants. METHODS This was a retrospective cohort study of ≤32 weeks VLBW infants born alive and admitted to Neonatal Intensive Care Unit (NICU) at King Abdulaziz Medical City-Jeddah (KAMC-Jeddah) between January 1, 1994, and December 31, 2019. The primary outcome of interest was the survival rate to discharge of VLBW infants delivered by cesarean section compared to delivered vaginally. Relevant demographic and clinical variables were assessed and its association to survival to discharge of VLBW infants were analyzed. RESULTS Of the 1055 ≤32 weeks VLBW infants included in the study, 559 (53%) were delivered by cesarean section, and 496 (47%) were delivered vaginally. Cesarean delivery had increased from 44.2% to 66% between 1994-1998 and 2014-2019, respectively. The rise of cesarean delivery compared with the vaginal delivery was more profound for gestational age ≤26 weeks and birth weight ≤800 g. The VLBW infants delivered by cesarean section had a higher survival rate when compared to infants delivered vaginally (87.29% vs 71.77%, P<0.001). The survival advantage was statistically significant in extremely low birth weight (ELBW) infants (801-1000 g) and infants with birth weight ≤800 g, 86.73% vs 73.62%, P=0.018 and 58.02% vs 40.52, P=0.001, respectively. Moreover, VLBW infants ≤26 weeks gestational age delivered by cesarean section had a higher survival rate of 69.15% vs 44.5%, P<0.001. CONCLUSION This study demonstrates that cesarean birth is associated with higher survival for VLBW infants with birth weight ≤800 g and ELBW infants and gestational age ≤26 weeks compared to vaginal birth.

Abstract
Bronchopulmonary dysplasia (BPD) is the most common respiratory disorder among infants born extremely preterm. The pathogenesis of BPD involves multiple prenatal and postnatal mechanisms affecting the development of a very immature lung. Their combined effects alter the lung's morphogenesis, disrupt capillary gas exchange in the alveoli, and lead to the pathological and clinical features of BPD. The disorder is ultimately the result of an aberrant repair response to antenatal and postnatal injuries to the developing lungs. Neonatology has made huge advances in dealing with conditions related to prematurity, but efforts to prevent and treat BPD have so far been only partially effective. Seeing that BPD appears to have a role in the early origin of chronic obstructive pulmonary disease, its prevention is pivotal also in long-term respiratory outcome of these patients. There is currently some evidence to support the use of antenatal glucocorticoids, surfactant therapy, protective noninvasive ventilation, targeted saturations, early caffeine treatment, vitamin A, and fluid restriction, but none of the existing strategies have had any significant impact in reducing the burden of BPD. New areas of research are raising novel therapeutic prospects, however. For instance, early topical (intratracheal or nebulized) steroids seem promising: they might help to limit BPD development without the side effects of systemic steroids. Evidence in favor of stem cell therapy has emerged from several preclinical trials, and from a couple of studies in humans. Mesenchymal stromal/stem cells (MSCs) have revealed a reparatory capability, preventing the progression of BPD in animal models. Administering MSC-conditioned media containing extracellular vesicles (EVs) have also demonstrated a preventive action, without the potential risks associated with unwanted engraftment or the adverse effects of administering cells. In this paper, we explore these emerging treatments and take a look at the revolutionary changes in BPD and neonatology on the horizon.

Effects on developmental outcomes after cesarean birth versus vaginal birth in Chinese children aged 1-59 months: a cross-sectional community-based survey. PeerJ 2019; 7:e7902. [PMID: 31660274 PMCID: PMC6815197 DOI: 10.7717/peerj.7902] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Accepted: 09/16/2019] [Indexed: 01/27/2023] Open
Abstract
OBJECTIVE It is controversial whether the mode of delivery is associated with developmental outcome, and little was known about growth and development of cesarean children in poor rural areas in China. We aim to measure the development of both cesarean and vaginal-delivered children by Ages and Stages Questionnaires (ASQ) and explore the association between mode of delivery and developmental outcome in poor rural areas in China. METHODS Data were collected from a cross-sectional community-based survey, which recruited 1,755 vaginal delivered and cesarean children ages 1 to 59 months in eight counties of China. Caregivers of those children completed the Chinese version of ASQ-3 (ASQ-C) while physical examination andquestionnaires on socio-demographic and neonatal characteristics were conducted. Multivariate logistic regressions were used to measure the association between developmental delay and mode of delivery as well as each socio-demographic factor, respectively, after adjusting other socio-demographic characteristics. RESULTS The prevalence of suspected overall developmental delay was 23.4% in the cesarean group, compared with 21.3% in the vaginal delivered group, yet without statistical difference (p < 0.05). Developmental delay was also not significantly different between cesarean and vaginal delivered group in five ASQ domains of communication (7.7% vs. 7.8%, p = 0.949), fine motor (7.0% vs. 6.1%, p = 0.538), gross motor (8.5% vs. 6.4%, p = 0.154), problem solving (7.2% vs. 6.7%, p = 0.722) and personal social (8.0% vs. 7.9%, p = 0.960). CONCLUSIONS Our findings suggest that cesarean delivery does not increase or decrease the risk of suspected developmental in children delay as compared with vaginal delivery.

Abstract
Background Benshangul Gumuze region is one of the regional states in Ethiopia, with highest rate of neonatal mortality rate. The trend increased at alarming rate from 42/1000 live birth in 2005 to 62/ 1000 live birth in 2011. Hence, identifying predictors of neonatal death and implement evidence based interventions at community level is crucial to reduce the mortality. Therefore, the purpose of this study was to identify predictors of neonatal mortality in Assosa zone, Western Ethiopia. Methods A community based matched case control study was conducted from February 1, until December 30, 2013. The study included 114 cases who died during the first 28 completed days after birth from September 1, 2010 till September 1, 2013. For each case, one alive control matched approximately by the same date of birth (−/+ 2 days) was identified from the preliminary data collected. Finally, multivariate conditional logistic regression analysis was performed; and goodness of fit of the final model was tested using likely hood ratio test. All analysis was done using EPI Info version 7 and SPSS version 16 statistical softwares. Results Model households in health extension packages [AmOR = 0.32; 95%CI:0.12–0.86], age at first pregnancy < 20 years old [AmOR = 4.3;95%CI: 1.13–16.27],pregnancy complication [AmOR = 4.59; 95%CI: 1.53–13.78], delivery complication [AmOR = 2.80; 95%CI: 1.06–7.39], antenatal care visit [AmOR = 0.34;95%CI: 0.12–0.94], primipara mothers [AmOR = 3.37; 95%CI:1.05–10.78], small size neonate at birth [AmOR = 3.40: 95%CI: 1.05–11.55], gestational age < 37 weeks [AmOR = 4.35;95%CI:1.16–16.28], and home delivery [AmOR = 2.84; 95%CI:1.07–7.55] were found statistically significantly associated with neonatal mortality. Conclusions Model households in health extension package and antenatal care visit were associated with reducing risk of neonatal mortality. However, age at first pregnancy < 20 years old, primipara mothers, pregnancy complication, delivery complication, small size neonates, gestational age < 37 weeks, and home delivery were associated with increasing risk of neonatal death. Therefore, promotion of model household in health extension package, anti natal care visit, institutional delivery, family planning to prevent early age pregnancy; and improve access to basic emergency obstetric care and intensive newborn care centers are effective interventions to reduce risk of neonatal mortality at community level.

Abstract
AIM The purpose of this systematic review was to provide an up-to-date global overview of the separate prevalences of motor and cognitive delays and cerebral palsy (CP) in very preterm (VPT) and very-low-birthweight (VLBW) infants. METHOD A comprehensive search was conducted across four databases. Cohort studies reporting the prevalence of CP and motor or cognitive outcome from 18 months corrected age until 6 years of VPT or VLBW infants born after 2006 were included. Pooled prevalences were calculated with random-effects models. RESULTS Thirty studies were retained, which included a total of 10 293 infants. The pooled prevalence of cognitive and motor delays, evaluated with developmental tests, was estimated at 16.9% (95% confidence interval [CI] 10.4-26.3) and 20.6% (95% CI 13.9-29.4%) respectively. Mild delays were more frequent than moderate-to-severe delays. Pooled prevalence of CP was estimated to be 6.8% (95% CI 5.5-8.4). Decreasing gestational age and birthweight resulted in higher prevalences. Lower pooled prevalences were found with the Third Edition of the Bayley Scales of Infant Development than with the Second Edition. INTERPRETATION Even though neonatal intensive care has improved over recent decades, there is still a wide range of neurodevelopmental disabilities resulting from VPT and VLBW births. However, pooled prevalences of CP have diminished over the years. WHAT THIS PAPER ADDS The Bayley Scales of Infant and Toddler Development, Third Edition reported lower pooled prevalences of motor and cognitive delays than the Second Edition. The pooled prevalence of cerebral palsy in infants born extremely preterm was reduced compared with previous meta-analyses.

Very low birth weight infants in China: the predictive value of the motor repertoire at 3 to 5months for the motor performance at 12months. Early Hum Dev 2016; 100:27-32. [PMID: 27391870 PMCID: PMC5010039 DOI: 10.1016/j.earlhumdev.2016.03.010] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 02/05/2016] [Accepted: 03/18/2016] [Indexed: 11/25/2022]
Abstract
BACKGROUND Studies on motor performance and its early markers are rare in China, especially in very low birth weight (VLBW) infants. OBJECTIVE Apart from the assessment of the inter-scorer agreement, we aimed to analyze to what extent the motor repertoire at 10 to 18weeks postterm was related to neonatal complications, and gross and fine motor performance at 12months after term. STUDY DESIGN Exploratory prospective study. SUBJECTS Seventy-four VLBW infants (58 males; mean gestational age=29weeks; mean birth weight=1252g). METHOD Five-minute video recordings were performed at 10 to 18weeks after term; fidgety movements and the concurrent motor patterns (resulting in a motor optimality score) were assessed according to the Prechtl general movements assessment (GMA). The gross and fine motor performance was assessed by means of the Peabody Developmental Motor Scales, second edition, at 12months. RESULTS Reliability was excellent. Pneumonia was associated with absent fidgety movements; the motor optimality score was lower in infants with pneumonia and/or bronchopulmonary dysplasia. Both absent fidgety movements and a lower motor optimality score were associated with a poor or very poor gross and fine motor performance at the 12-month-assessment. CONCLUSION Both the assessment of fidgety movements and the evaluation of the concurrent motor repertoire contribute significantly to an identification of VLBW children with a poor gross and fine motor outcome at 12months. The results of this study document the need for an early identification of infants at high risk for a poor motor performance.

Abstract
OBJECTIVE Little is known regarding the impact of mode of delivery in the periviable period. Even less is understood regarding the effect of mode of delivery on neurodevelopment. Our objective is to determine if the mode of delivery at time of periviability impacts Bayley II scores at 2 years of age. STUDY DESIGN This is a secondary analysis of a randomized, controlled trial of magnesium sulfate for the prevention of cerebral palsy, a multicenter trial where women at imminent risk for delivery were assigned to receive magnesium sulfate or placebo. For this secondary analysis we included nonanomalous singleton gestations delivered between 23 4/7 and 25 6/7 weeks. We excluded women with missing exposure or outcome data. The primary exposure of interest was mode of delivery. The primary outcome was Bayley II scores <70 (mental and motor) at 2 years of age. Log binomial regression was used to control for possible confounders including gestational age at delivery, presentation at time of delivery, chorioamnionitis, years of maternal education, maternal body mass index, and original study treatment group. RESULTS A total of 158 women met inclusion criteria. In all, 91 had a vaginal delivery and 67 had a cesarean delivery. Exposure to magnesium sulfate, maternal education, chorioamnionitis, years of maternal education, and maternal body mass index were similar in both groups. There was no difference in either mental or motor Bayley II scores <70 or <85 by mode of delivery in either univariable or multivariable analysis. CONCLUSION There is no detectable difference in Bayley II scores between mode of delivery at time of periviability. This adds to the literature supporting obstetric indications dictating mode of delivery at this gestational age.
