Sex differences, asymmetry, and age-related white matter development in infants and 5-year-olds as assessed with tract-based spatial statistics. Hum Brain Mapp 2023; 44:2712-2725. [PMID: 36946076 PMCID: PMC10089102 DOI: 10.1002/hbm.26238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 01/24/2023] [Accepted: 02/08/2023] [Indexed: 03/23/2023] Open
Abstract
The rapid white matter (WM) maturation of first years of life is followed by slower yet long-lasting development, accompanied by learning of more elaborate skills. By the age of 5 years, behavioural and cognitive differences between females and males, and functions associated with brain lateralization such as language skills are appearing. Diffusion tensor imaging (DTI) can be used to quantify fractional anisotropy (FA) within the WM and increasing values correspond to advancing brain development. To investigate the normal features of WM development during early childhood, we gathered a DTI data set of 166 healthy infants (mean 3.8 wk, range 2-5 wk; 89 males; born on gestational week 36 or later) and 144 healthy children (mean 5.4 years, range 5.1-5.8 years; 76 males). The sex differences, lateralization patterns and age-dependent changes were examined using tract-based spatial statistics (TBSS). In 5-year-olds, females showed higher FA in wide-spread regions in the posterior and the temporal WM and more so in the right hemisphere, while sex differences were not detected in infants. Gestational age showed stronger association with FA values compared to age after birth in infants. Additionally, child age at scan associated positively with FA around the age of 5 years in the body of corpus callosum, the connections of which are important especially for sensory and motor functions. Lastly, asymmetry of WM microstructure was detected already in infants, yet significant changes in lateralization pattern seem to occur during early childhood, and in 5-year-olds the pattern already resembles adult-like WM asymmetry.

[PMID: 36339635 PMCID: PMC9633228 DOI: 10.1055/a-1904-6025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Accepted: 07/16/2022] [Indexed: 11/07/2022] Open
Abstract
Introduction Vacuum extraction (VE) is an important modality in modern obstetrics, yet sometimes results in maternal or neonatal adverse outcomes, which can cause a lifetime disability. We aimed to characterize potential risk factors for adverse outcomes that in retrospect would have led the physician to avoid the procedure. Materials and Methods Retrospective cohort of 3331 singleton pregnancies, ≥ 34 w delivered by VE. 263 deliveries (7.9%) incurred a VE-related feto-maternal adverse outcome, defined as one or more of the following: 3-4th-degree perineal laceration, subgaleal hematoma, intracranial hemorrhage, shoulder dystocia, clavicular fracture, Erb's palsy or fracture of humerus. 3068 deliveries (92.1%) did not have VE-related adverse outcomes. Both groups were compared to determine potential risk factors for VE adverse outcomes. Results Multivariable regression found seven independent risk factors for VE-related feto-maternal adverse outcomes: Nulliparity - with an odds ratio (OR) of 1.82 (95% CI = 1.11-2.98, p = 0.018), epidural anesthesia (OR 1.99, CI = 1.42-2.80, p < 0.001), Ventouse-Mityvac (VM) cup (OR 1.86, CI = 1.35-2.54, p < 0.001), prolonged second stage as indication for VE (OR 1.54, CI = 1.11-2.15, p = 0.010), cup detachment (OR 1.66, CI = 1.18-2.34, p = 0.004), increasing procedure duration (OR 1.07 for every additional minute, CI = 1.03-1.11, p < 0.001) and increasing neonatal birthweight (OR 3.42 for every additional kg, CI = 2.33-5.02, p < 0.001). Occiput anterior (OA) position was a protective factor (OR 0.62, CI = 0.43-0.89, p = 0.010). Conclusions VE-related adverse outcomes can be correlated to clinical characteristics, such as nulliparity, epidural anesthesia, VM cup, prolonged second stage as indication for VE, cup detachment, prolonged procedure duration and increasing neonatal weight. OA position was a protective factor. This information may assist medical staff to make an informed decision whether to choose VE or cesarean delivery (CD).

Abstract
PURPOSE To evaluate neonatal and maternal outcomes associated with detachment of non-metal vacuum cup during delivery and to identify risk factors for these detachments. METHODS This retrospective cohort study included women with singleton pregnancy, who underwent vacuum-assisted vaginal delivery with a non-metal vacuum cup in a single academic institution, January 2014-August 2019. Failed vacuum deliveries were excluded. Primary outcomes were defined as subgaleal hematoma (SGH) and cord blood pH < 7.15. Secondary outcome included other neonatal complications and adverse maternal outcomes. Outcomes were compared between vacuum-assisted deliveries with and without cup detachment during the procedure. RESULTS A total of 3246 women had successful VAD and met the inclusion criteria. During the procedure, the cup detached at least once in 665 (20.5%) deliveries and did not detach in 2581 (79.5%). The cup detachment group experienced higher rates of SGH (8.9% vs. 3.5%, p = 0.001) and cord blood pH < 7.15 (9.8% vs. 7.1%, p = 0.03). There were also more neonatal intensive care unit admissions (NICU) (4.4% vs. 2.7%, p = 0.03) and more fetuses with occiput posterior position (70.8% vs. 79.4%, p = 0.001), the vacuum duration was slightly longer (6 ± 3.7 vs. 5 ± 2.9 min) and more neonates had birth weights > 3700 g (14.1% vs, 10.3%, p = 0.006). Interestingly, there were more males in that group (60.6 vs. 54.6, p = 0.005). All these factors remained significant after controlling for potential confounders. CONCLUSIONS Vacuum cup detachment has several predictive characteristics and is associated with adverse neonatal outcomes that should be incorporated into decisions made during the procedure.

Abstract
Background: Perinatal asphyxia is a significant contributing factor for neonatal morbidity and mortality. The aim of this study was to investigate the clinical factors associated with umbilical artery pH variability and fetal acidosis at birth. Methods: This is a single center cross-sectional study in a public regional hospital in southeastern Spain from January to December 2019. The reference population was 1.655 newborns, final sample of 312 experimental units with validated values of umbilical cord blood pH. Results: Factors such as gestational age at term ( X ¯ at - term : 7.26 ± 0.08- X ¯ no -at-term: 7.31 ± 0.05, p: 0.00), primiparity ( X ¯ primiparity : 7.24 ± 0.078- X ¯ multiparity : 7.27 ± 0.08, p: 0.01), induced labor ( X ¯ induced : 7.24 ± 0.07- X ¯ spontaneous : 7.26 ± 0.081, p: 0.02), vaginal delivery ( X ¯ vaginal :7.25 ± 0.08- X ¯ cesarean :7.27 ± 0.07, p: 0.01), and prolonged dilation duration ( X ¯ AboveAverage : 7.22 ± 0.07- X ¯ BelowAverage : 7.27 ± 0.08, p: 0.00), expulsion duration ( X ¯ AboveAverage : 7.23 ± 0.07- X ¯ BelowAverage : 7.26 ± 0.08, p: 0.01), and total labor duration ( X ¯ AboveAverage : 7.23 ± 0.07- X ¯ BelowAverage : 7.27 ± 0.08, p: 0.00) are associated with a decrease in umbilical artery pH at birth. However, only three factors are associated with acidosis pH (<7.20) of the umbilical artery at birth: the induction of labor [OR: 1.74 (95% CI: 0.98-3.10); p: 0.04], vaginal delivery [OR: 2.09 (95% CI: 0.95-4.61); p: 0.04], and total duration of labor [OR: 2.06 (95% CI: 1.18-3.57); p: 0.01]. Conclusions: Although several factors may affect the variability of umbilical artery pH at birth by decreasing their mean values (gestational age, primiparity, induced labor, vaginal delivery and prolonged: dilation duration, expulsion duration and total labor duration), only induction of labor, vaginal delivery and total duration of labor are associated with an acidosis (<7.20) of same.

Abstract
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.

Abstract
Background: Birth is a traumatic event with molding forces directed to the fetal skull, which may result in intracranial hemorrhages. However, the knowledge on prevalence and risk factors of incidental brain magnetic resonance imaging (MRI) findings in infants is still inconclusive. Methods: The prevalence and nature of incidental MRI findings were assessed in a birth cohort of 175 asymptomatic infants. The role of delivery method as well as other potential risk factors for intracranial hemorrhages were evaluated. The infants underwent 3T MRI at the age of 2–5 weeks, and the neurological status of the infants with an incidental finding was evaluated by a pediatric neurologist. Information on the delivery method, duration of delivery, parity, used anesthesia, oxytocin induction, and Apgar score was gathered to evaluate their association with the prevalence of hemorrhages. Results: Incidental intracranial hemorrhages were detected in 12 infants (6.9%), all following spontaneous or assisted vaginal delivery. Vacuum-assistance was found to be a risk factor for subdural hemorrhages with an odds ratio (OR) of 4.7 (95% CI [1.18; 18.9], p = 0.032). All infants were evaluated to develop normally by their clinical status. Conclusions: Incidental intracranial hemorrhages are relatively common among infants born by vaginal delivery. They are often of little clinical significance within the first years of life and have unlikely consequences for later neurodevelopment either. Despite their benign character, investigators should be prepared to share this information with parents competently as the findings can cause parental anxiety, and especially as the popularity of MRI as a research tool is increasing.

Abstract
BACKGROUND Concern exists regarding a possible harmful impact of vacuum extraction on the preterm newborn. We aimed to evaluate the long-term pediatric neurodevelopmental outcomes of the preterm offspring after vacuum extraction. METHODS A population-based cohort analysis was performed comparing the risk for long-term neurological morbidity (up to age 18 years) in preterm (less than 37 completed weeks of gestation) children born via following three delivery modes: vacuum extraction, spontaneous delivery, and Caesarean delivery performed during the second stage of labor. A Kaplan-Meier survival curve was used to compare the cumulative neurological morbidity in all groups. A Cox proportional hazards model was used to control for confounders. RESULTS During the study period 11,662 preterm newborns met the inclusion criteria, 97.2% (n = 11,338) of which were born via spontaneous vaginal delivery, 2.3% (n = 267) underwent vacuum extraction, and 0.5% (n = 57) were delivered by Caesarean section during the second stage of labor. Gestational age at delivery median (range) was 36 (29 to 36) weeks for vacuum extractions, 36 (23 to 36) for spontaneous vaginal delivery, and 35 (29 to 36) for Caesarean delivery within second stage of labor. Total pediatric hospitalizations involving neurological diagnoses were comparable between the groups as were the cumulative incidences of total neurological morbidity in the survival curves (log rank P = 0.723). In the Cox regression model, vacuum delivery in preterm newborns was not found to be associated with later pediatric neurological hospitalizations. CONCLUSIONS Vacuum extraction performed on preterm newborns does not appear to be independently associated with severe long-term neurological morbidity, as reflected by later pediatric hospitalizations.
