Abstract
OBJECTIVES To assess sex-specific differences in the association between pre-transfusion haemoglobin values and early neurodevelopmental function. DESIGN Observational follow-up of infants with birth weights <1000 g and gestational ages 22-28 weeks who were enrolled in the NICHD Neonatal Research Network Transfusion of Prematures (TOP) Trial at 19 U.S. sites, 2012-2017. MAIN OUTCOME MEASURES Pretransfusion haemoglobin values were obtained longitudinally through 36 weeks' postmenstrual age. The infant's mean pretransfusion haemoglobin was used as a marker of degree of anaemia (n=1655 measures). Measures of brain function were obtained at 22-26 months' corrected age using the Bayley Scales of Infant & Toddler Development, third edition (BSID-III) (n=1290 BSID-III scores). Sex-specific estimates for the linear relation between pretransfusion haemoglobin and BSID-III scores were obtained from repeated-measures regression analysis, adjusted for gestational age, birth weight, study site, clinical characteristics, and demographic covariates. RESULTS The relation of pretransfusion haemoglobin with 24-month BSID-III scores showed significant, independent interactions with both (1) sex (p=0.046) and (2) retinopathy of prematurity (ROP; p=0.004). In 614 males, BSID-III scores were higher by 1.07 points per g/dL (95% CI 1.58 to 4.33; p=0.008), not differing significantly among the three subscales (cognitive, language and motor; p=0.94). In 247 infants with ROP, BSID-III scores were higher by 2.95 points per g/dL (95% CI 0.28 to 1.87; p<0.0001), uniformly across subscales (p=0.73). These associations were non-significant in 676 females (p=0.96) and 1043 infants without ROP (p=0.81). CONCLUSIONS This study demonstrates sex-specific associations between mean pretransfusion haemoglobin (a marker of the severity of anaemia throughout the neonatal intensive care unit [NICU] hospitalisation) and early neurodevelopmental function at 22-26 months' corrected age.

Cord blood granulocyte Colony-Stimulating factor level as an optimal predictor of umbilical cord arteritis associated with brain injury at term equivalent age in preterm neonates. Cytokine 2023; 171:156369. [PMID: 37751674 DOI: 10.1016/j.cyto.2023.156369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 09/08/2023] [Accepted: 09/12/2023] [Indexed: 09/28/2023]
Abstract
OBJECTIVE The study aimed 1) to evaluate the association between the presence or absence of umbilical cord arteritis (UCA) and the cord blood cytokine levels, and 2) morbidity and mortality of preterm neonates; and 3) to identify predictive markers for UCA of preterm neonates. STUDY DESIGN In this single-center retrospective observational cohort study, preterm neonates born at gestational age (GA) < 36 weeks were categorized pathologically according to the severity of intrauterine inflammation; those without UCA as Group 1, those with UCA as Group 2, and those without any intrauterine inflammation as Group 3 (control), and subgroup analyses classified by their GA were performed. We compared morbidity and mortality, and eight representative cytokine levels in cord blood samples between the groups. Subsequently, receiver operating characteristics (ROC) curves for UCA diagnosis for each cytokine were created, and values of areas under the curve (AUC) were calculated to determine the optimal predictive markers. RESULTS In total, 105 patients (36, 58, and 11 in Groups 1, 2, and 3, respectively) were included. Multivariate logistic analysis revealed that patients with UCA had higher incidence of brain injury (Odds Ratio [OR] = 8.53, P = 0.0049, 95% Confidence Interval [CI]: 1.91 - 38.0), at term equivalent age in the subgroup analysis with GA < 32 weeks. Although the median value of cord blood granulocyte colony-stimulating factor (G-CSF) was significantly higher in Group 2 than in Group 1 or 3, only the G-CSF level was found to be high in the subgroup analysis with GA < 32 weeks. For UCA diagnosis, the AUC values of G-CSF were the highest among eight cytokines including interleukin 6 (IL-6). These findings were similar in the subgroup analysis with GA < 32 weeks. CONCLUSIONS Preterm neonates, especially born at GA < 32 week, had higher morbidity from brain injury in the group with UCA. The cord blood G-CSF level was highly accurate for predicting UCA and could thus be used as an optimal biomarker.

Intra-amniotic inflammation in the mid-trimester of pregnancy is a risk factor for neuropsychological disorders in childhood. J Perinat Med 2023; 51:363-378. [PMID: 36173676 PMCID: PMC10010737 DOI: 10.1515/jpm-2022-0255] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 07/17/2022] [Indexed: 11/15/2022]
Abstract
OBJECTIVES Intra-amniotic inflammation is a subclinical condition frequently caused by either microbial invasion of the amniotic cavity or sterile inflammatory stimuli, e.g., alarmins. An accumulating body of evidence supports a role for maternal immune activation in the genesis of fetal neuroinflammation and the occurrence of neurodevelopmental disorders such as cerebral palsy, schizophrenia, and autism. The objective of this study was to determine whether fetal exposure to mid-trimester intra-amniotic inflammation is associated with neurodevelopmental disorders in children eight to 12 years of age. METHODS This is a retrospective case-control study comprising 20 children with evidence of prenatal exposure to intra-amniotic inflammation in the mid-trimester and 20 controls matched for gestational age at amniocentesis and at delivery. Amniotic fluid samples were tested for concentrations of interleukin-6 and C-X-C motif chemokine ligand 10, for bacteria by culture and molecular microbiologic methods as well as by polymerase chain reaction for eight viruses. Neuropsychological testing of children, performed by two experienced psychologists, assessed cognitive and behavioral domains. Neuropsychological dysfunction was defined as the presence of an abnormal score (<2 standard deviations) on at least two cognitive tasks. RESULTS Neuropsychological dysfunction was present in 45% (9/20) of children exposed to intra-amniotic inflammation but in only 10% (2/20) of those in the control group (p=0.03). The relative risk (RR) of neuropsychological dysfunction conferred by amniotic fluid inflammation remained significant after adjusting for gestational age at delivery [aRR=4.5 (1.07-16.7)]. Of the 11 children diagnosed with neuropsychological dysfunction, nine were delivered at term and eight of them had mothers with intra-amniotic inflammation. Children exposed to intra-amniotic inflammation were found to have abnormalities in neuropsychological tasks evaluating complex skills, e.g., auditory attention, executive functions, and social skills, whereas the domains of reasoning, language, and memory were not affected in the cases and controls. CONCLUSIONS Asymptomatic sterile intra-amniotic inflammation in the mid-trimester of pregnancy, followed by a term birth, can still confer to the offspring a substantial risk for neurodevelopmental disorders in childhood. Early recognition and treatment of maternal immune activation in pregnancy may be a strategy for the prevention of subsequent neurodevelopmental disorders in offspring.

Abstract
AIM Antenatal corticosteroids (ACS) are recommended for women at risk of preterm birth before 34 weeks' gestation. However, adverse effects of ACS on the fetal brain have also been reported. The time interval from ACS administration to delivery (ACS-to-delivery interval) might alter the effect of ACS on the fetal brain. This study aimed to evaluate the effect of ACS-to-delivery interval on cord blood S100 calcium-binding protein B (S100B) levels as a biomarker of brain damage. METHODS Women who delivered between 2012 and 2020 at a tertiary medical center were divided into three groups according to ACS use and ACS-to-delivery interval, retrospectively: non-ACS, ACS ≤7 days, and ACS >7 days. Patients who did not complete the ACS regimen were excluded. The primary outcome was cord blood S100B levels. RESULTS Cord blood S100B levels were significantly lower in the ACS ≤7 days group than in the non-ACS and ACS >7 days groups. In the multiple regression analysis, birth ≤7 days after ACS showed a significant negative association with S100B level (p < 0.001). CONCLUSIONS Reduced S100B levels were observed in infants born ≤7 days after ACS but not in infants born >7 days after ACS. These findings suggest the importance of ACS timing to optimize its effects on the fetal brain, although further studies are required to identify these mechanisms.

Abstract
BackgroundWe compared the neuroprotective effects of Fingolimod (fng), a neuroprotective and anti-inflammatory drug, with that of magnesium sulfate (MgSO4), alone and in combination, in fetal rat whose mothers were exposed to endotoxin.MethodSeven groups of pregnant rats (28 total) were evaluated at 0.8 gestation - Group1 - saline only; 2 - endotoxin only; 3 - endotoxin + MgSO4; 4 - endotoxin + fng; 5 - endotoxin + MgSO4 + fng; 6 - saline + fng; 7 - saline + MgSO4 + fng. Preterm labor was induced 4 h after intraperitoneal endotoxin administration. Fetal brain samples were examined immunohistochemically using S100β, IL-6, and IL-10.ResultsEndotoxin caused increased expression of S100β, IL-6, and IL-10. Compared with MgSO4 alone, combined treatment was associated with lower expression of IL-10, IL-6 and S100 β.ConclusionFng decreases inflammatory markers after in-utero exposure to endotoxin, has a synergistic effect combined with MgSO4, and may be a candidate neuroprotective drug for inflammation-induced preterm brain injury.

Abstract
OBJECTIVE To assess sex-specific differences in early brain structure and function of preterm infants after red blood cell (RBC) transfusions. STUDY DESIGN A single-center subset of infants with a birth weight <1000 g and gestational age 22-29 weeks were enrolled from the National Institute of Child Health and Human Development's Neonatal Research Network Transfusion of Prematures Trial. Hemoglobin (Hb) concentration obtained directly before each transfusion (pretransfusion Hb [ptHb]) was obtained longitudinally throughout each infant's neonatal intensive care unit stay and used as a marker of degree of anemia (n = 97). Measures of regional brain volumes using magnetic resonance imaging were obtained at ∼40 weeks postmenstrual age or at hospital discharge, if earlier (n = 29). Measures of brain function were obtained at 12 months corrected age using the Bayley Scales of Infant & Toddler Development, 3rd Edition (n = 34). RESULTS PtHb was positively correlated with neonatal cerebral white matter volume in males (B = +0.283; P = .006), but not females (B = -0.099; P = .713), resulting in a significant sex interaction (P = .010). Bayley-III gross motor scores and a pooled mean score were significantly lower in association with higher ptHb in females (gross motor score: B = -3.758; P = .013; pooled mean score: B = -1.225; P = .030), but not males (gross motor score: B = +1.758; P = .167; pooled mean score: B = +0.621; P = .359). Higher ptHb was associated with descriptively lower performance on multiple Bayley-III subscales in females, but not in males. CONCLUSIONS This study demonstrates sex-specific associations between an early marker of anemia and RBC transfusion status (ie, ptHb) with both neonatal white matter volume and early cognitive function at age 12 months in preterm infants.

Sex-specific cytokine responses and neurocognitive outcome after blood transfusions in preterm infants. Pediatr Res 2022; 91:947-954.

Abstract
BACKGROUND The objective of this study was to determine sex-specific differences in inflammatory cytokine responses to red blood cell (RBC) transfusion in preterm infants in the neonatal period and their relationship to later neurocognitive status. METHODS Infants with a birth weight <1000 g and gestational age 22-29 weeks were enrolled in the Transfusion of Prematures (TOP) trial. The total number of transfusions was used as a marker of transfusion status. Nineteen cytokines and biomarkers were analyzed from 71 infants longitudinally during the neonatal period. Twenty-six infants completed the Bayley Scales of Infant & Toddler Development, 3rd Edition (Bayley-III) at 12 months' corrected age. RESULTS Nine cytokine levels were significantly elevated in proportion to the number of transfusions received. Of those, one cytokine showed a sex-specific finding (p = 0.004): monocyte chemoattractant protein-1, MCP-1, rose substantially in females (8.9% change per additional transfusion), but not in males (-0.8% change). Higher concentrations of MCP-1 exclusively were associated with worse Bayley-III scores: decreased cognitive raw scores (p = 0.0005) and motor scaled scores (p < 0.0001). CONCLUSIONS This study provides evidence of a sex-specific difference in the inflammatory response to RBC transfusions during neonatal life, with MCP-1 levels rising only in females and inversely correlating with neurocognitive status at 12 months old. IMPACT It is important to understand the risk factors for abnormal neurodevelopment in preterm infants, including anemia and RBC transfusion, in order to improve outcomes and provide potential targets for therapy. Our study investigates and provides the first evidence of sex-specific differences in inflammatory cytokine responses to RBC transfusions in preterm infants in the neonatal period, and their relationship to later cognitive outcomes. This study critically suggests that different transfusion thresholds may have a sex-specific effect on neurodevelopment: females have worse cognitive outcomes with increased number of transfusions, while males have worse outcomes with lower number of transfusions.

Abstract
OBJECTIVES S100B belongs to the family of danger signaling proteins. It is mainly expressed by glial-specific cells in the brain. However, S100B was also detected in other cell likewise immune cells. This molecule was suggested as biomarker for inflammation and fetal brain damage in spontaneous preterm birth (sPTB), preeclampsia (PE) and HELLP (hemolysis, elevated liver enzymes, and low platelet count). METHODS The aim of our study was to determine the concentration of S100B in maternal and cord blood (CB) plasma and placenta supernatant as well as the expression of S100B in maternal and CB CD4+ T cells and CD19+ B cells in sPTB and patients delivering following PE/HELLP diagnosis compared to women delivering at term (TD). The S100B expression was further related to the birth weight in our study cohort. RESULTS S100B concentration was enhanced in maternal and CB plasma of sPTB and PE/HELLP patients and positively correlated with interleukin-6 (IL-6) levels. Increased S100B was also confirmed in CB of small-for-gestational-age (SGA) infants. S100B expression in maternal blood was elevated in CD4+ T cells of PE/HELLP patients and patients who gave birth to SGA newborns as well as in CD19+ B cells of sPTB and PE/HELLP patients and patients with SGA babies. In CB, the expression of S100B was increased in CD19+ B cells of sPTB, PE/HELLP and SGA babies. CONCLUSIONS Our results support the hypothesis that S100B expression is enhanced in inflammatory events associated with preterm birth and that S100B expression in immune cells is a relevant marker for inflammation during pregnancy complications.

A Prospective Case-Control Longitudinal Study in Human Premature Neonates. Brain Sci 2021; 11:brainsci11091243. [PMID: 34573263 PMCID: PMC8468004 DOI: 10.3390/brainsci11091243] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 09/13/2021] [Accepted: 09/16/2021] [Indexed: 01/02/2023] Open
Abstract
Disruption of normal intrauterine brain development is a significant consequence of premature birth and may lead to serious complications, such as neonatal brain injury (NBI). This prospective case-control longitudinal study aimed at determining the levels and prognostic value of serum activin A during the first three days of life in human premature neonates which later developed NBI. It was conducted in a single tertiary hospital and eligible participants were live-born premature (<34 weeks) neonates. Each case (n = 29) developed NBI in the form of an intraventricular haemorrhage, or periventricular leukomalacia, and was matched according to birth weight and gestational age to one neonate with normal head ultrasound scans. Serum activin A levels in both groups showed a stable concentration during the first three days of life as no difference was observed within the two groups from the first to the third day. Neonates diagnosed with NBI had significantly higher activin A levels during the first two days of life compared to control neonates and its levels correlated to the severity of NBI during the second and third day of life. Although serum activin A on the second day was the best predictor for neonates at risk to develop NBI, the overall predictive value was marginally fair (area under the ROC-curve 69.2%). Activin A, in combination with other biomarkers, may provide the first clinically useful panel for the early detection of premature neonates at high risk of NBI.

Abstract
Background Neurological complications are common in the premature and full-term neonates admitted to the intensive care unit, but the diagnosis of these complications is often difficult to make. S100B protein, measured in cord blood, may represent a valuable tool to better identify patients at risk of brain injury. Methods As a first step, we established S100B cord blood serum reference intervals from 183 preterm and 200 full-term neonates. We then measured cord blood serum S100B to identify neurological complications in 272 neonates hospitalized at the neonatal intensive care unit (NICU). Diagnosis of brain injury relied on imaging examination. Results The 95th percentiles of S100B concentration in cord blood were established as 1.21 μg/L for the 383 neonates, 0.96 μg/L for full-term neonates and 1.36 μg/L for premature neonates. Among the 272 neonates hospitalized at the NICU, 11 presented neurological complications. Using 1.27 μg/L as the optimal sensitivity/specificity threshold, S100B differentiate neonates with and without neurological complications with a sensitivity of 45.5% (95% confidence intervals [CI]: 16.7-76.6) and a specificity of 88.9% (95% CI: 84.4-92.4) (p = 0.006). In combination with arterial pH (<7.25), sensitivity increased to 90.9% (95% CI: 58.7-99.8), while specificity was 51.2% (95% CI: 44.8-57.7). The sensitivity is significantly (p = 0.03) increased in comparison to S100B alone. The specificity is significantly higher with S100B only than with pH + S100B (p < 0.001). Conclusions Cord blood S100B protein, in combination with arterial cord blood pH, has the potential to help clinicians to detect at birth neurological complications in neonates hospitalized in an NCIU.

Abstract
Background: This study was performed to investigate the clinical significance of miR-4535 and miR-1915-5p in severe chorioamnionitis. Materials & methods: Amniotic fluid samples from 37 patients with severe chorioamnionitis were subjected to miRNA array analysis and ddPCR™. Diagnostic values were assessed using the receiver operating characteristic curve. The patients were separated into three groups according to Blanc’s criteria. Results: The expression of miR-4535 and miR-1915-5p was significantly correlated with the copy number of 16S rDNA, had extremely high diagnostic accuracy for severe chorioamnionitis, and was linked to maternal and fetal inflammation. Conclusion: miR-4535 and miR-1915-5p serve as promising biomarkers for the diagnosis of severe chorioamnionitis. Chorioamnionitis and fetal inflammatory response syndrome, which is linked to chorioamnionitis, are considered serious diseases in perinatal care. In this study, miR-4535 and miR-1915-5p are recognized as promising biomarkers for the diagnosis of chorioamnionitis before delivery. In particular, the increased expression of miR-4535 in amniotic fluid is expected to be regarded as a positive indicator for fetal inflammatory response syndrome, and the elevated expression of miR-4535 in serum is also considered to predictively diagnose intrauterine infection in pregnancy. Our results highlight that further studies should explore the underlying clinical significance of miR-4535 and miR-1915-5p.

Abstract
OBJECTIVES To investigate the distribution of multiple cytokines in gastroschisis and reveal its association with clinical outcomes, including gastrointestinal disorders and fetal brain damage caused by chronic inflammation in gastroschisis. METHODS We obtained amniotic fluid and arterial cord blood from 10 patients with gastroschisis, and evaluated the profile of 40 cytokines via multiplex immunoassay. The possible relationship of the cytokines with the time taken to attain full enteral nutrition and cord S100B, a surrogate marker of brain damage, was estimated. Associations among the relevant cytokines were also assessed. RESULTS Although clinical characteristics in our cohort had no relevance, several cytokines in cord blood, especially IL-2, IL-8, CCL1, CCL7, CXCL1, CXCL2, and CXCL6, were clearly elevated in patients who took a longer time to attain full enteral nutrition, whereas only IL-16 in cord blood was significantly related to cord S100B and strongly correlation with cord S100B levels. Moreover, our data indicated that IL-16 was considerably less correlated with the other cytokines associated with adverse outcomes. CONCLUSIONS We investigated the cytokine characteristics of both amniotic fluid and cord blood in gastroschisis, and found that certain cytokines could affect the adverse outcomes, including fetal brain damage. These findings provide important information that could further clarify the pathophysiology of gastroschisis and propose a novel clinical implication of gastroschisis that could be used to predict adverse outcomes, especially neurodevelopmental disorders.

Abstract
Encephalopathy of prematurity (EoP) is a major cause of morbidity in preterm neonates, causing neurodevelopmental adversities that can lead to lifelong impairments. Preterm birth-related insults, such as cerebral oxygen fluctuations and perinatal inflammation, are believed to negatively impact brain development, leading to a range of brain abnormalities. Diffuse white matter injury is a major hallmark of EoP and characterized by widespread hypomyelination, the result of disturbances in oligodendrocyte lineage development. At present, there are no treatment options available, despite the enormous burden of EoP on patients, their families, and society. Over the years, research in the field of neonatal brain injury and other white matter pathologies has led to the identification of several promising trophic factors and cytokines that contribute to the survival and maturation of oligodendrocytes, and/or dampening neuroinflammation. In this review, we discuss the current literature on selected factors and their therapeutic potential to combat EoP, covering a wide range of in vitro, preclinical and clinical studies. Furthermore, we offer a future perspective on the translatability of these factors into clinical practice.

Abstract
BACKGROUND Neonatal brain injury (NBI) is a serious adverse outcome in premature neonates. We sought to determine the levels and prognostic value of serum S100B during the first three days of life in premature neonates (<34 weeks) that later developed NBI in the form of either intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL). METHODS This is a prospective case - control longitudinal study. Each case (n = 29) was matched according to birthweight and gestational age to one neonate with normal head ultrasound scans. RESULTS Neonates with NBI, had significantly higher S100B concentration during the first three days of life. In both groups S100B was significantly higher on the first day when compared to the next two days of life showing a downwards trend. Serum S100B on the first day was the best predictor for adverse neonatal outcome such as death or II-IV IVH grade. A cut-off value of 10.51 ng/ml serum S100B performed a sensitivity of 100% and a specificity of 93.9% to predict adverse neonatal outcome. CONCLUSION Further research on the predictive value of serum S100B regarding NBI in premature neonates is of great interest and may provide the first clinically useful biomarker for early detection of neonates at high risk.

Abstract
The early detection of perinatal brain damage in preterm and term newborns (i.e. intraventricular hemorrhage, periventricular leukomalacia and perinatal asphyxia) still constitute an unsolved issue. To date, despite technological improvement in standard perinatal monitoring procedures, decreasing the incidence of perinatal mortality, the perinatal morbidity pattern has a flat trend. Against this background, the measurement of brain constituents could be particularly useful in the early detection of cases at risk for short-/long-term brain injury. On this scenario, the main European and US international health-care institutions promoted perinatal clinical and experimental neuroprotection research projects aimed at validating and including a panel of biomarkers in the clinical guidelines. Although this is a promising attempt, there are several limitations that do not allow biomarkers to be included in standard monitoring procedures. The main limitations are: (i) the heterogeneity of neurological complications in the perinatal period, (ii) the small cohort sizes, (iii) the lack of multicenter investigations, (iv) the different techniques for neurobiomarkers assessment, (iv) the lack of consensus for the validation of assays in biological fluids such as urine and saliva, and (v), the lack of reference curves according to measurement technique and biological fluid. In the present review we offer an up-to-date overview of the most promising developments in the use of biomarkers in the perinatal period such as calcium binding proteins (S100B protein), vasoactive agents (adrenomedullin), brain biomarkers (activin A, neuron specific enolase, glial fibrillary acidic protein, ubiquitin carboxyl-terminal hydrolase-L1) and oxidative stress markers.

Abstract
OBJECTIVES Few studies have investigated the distribution of multiple cytokines in fetal pleural effusion, and its clinical implications are uncertain. This study aimed to determine cytokine levels in fetal pleural effusion and their clinical role in affected fetuses. METHODS We obtained fetal pleural fluid samples from 18 infants and investigated the profiles of 40 cytokines using multiplex immunoassay. Relationships among cytokines were estimated by Spearman correlation analysis. Possible associations of cytokine levels with fetal adverse outcomes, including perinatal demise and neurodevelopmental impairment, were studied using univariate logistic regression analysis. RESULTS Several pro-inflammatory cytokines and CCL chemokines were highly correlated with each other. In contrast, CXCL chemokines had relatively weak correlations with other cytokines. The levels of IL-1β, IL-2, and CCL20 were significantly associated with the occurrence of fetal adverse outcomes. Based on our findings, IL-1β had the strongest causal link to adverse outcomes among the cytokines [odds ratio (OR): 19.74; 95% confidence interval (CI): 1.14-341.9; p = 0.040]. CONCLUSIONS Cytokine levels in fetal pleural effusion varied considerably among cases with or without adverse outcomes. These results provide important information for further clarifying the pathophysiology of fetal pleural effusion and a novel clinical implication that could predict the occurrence of adverse outcomes.

Abstract
While the survival rate of preterm infants has continually increased with the development of perinatal and neonatal monitoring techniques, the incidence of brain injury in preterm infants has been increasing, resulting in varying degrees of cognitive impairment and movement disorders. Measuring the biomarkers of brain damage is an important means to diagnose brain injury. The biomarkers can be divided into neuroglial damage markers, neuronal damage markers and other markers according to the features of injured cells. The biomarkers widely used in clinical practice include S100B protein, myelin basic protein and neuron-specific enolase. Recent studies have newly discovered a collection of markers that can suggest potential brain injury in preterm infants, such as glial fibrillary acidic protein, neurofilament light chain protein, α-II spectrin breakdown products, chemokines, melatonin and urinary metabolomics. These biomarkers can contribute to the early diagnosis and treatment of preterm brain injury, essential for improving neural development and prognosis. This article reviews the latest research advances in the biomarkers of preterm brain injury, in order to provide evidence for the early diagnosis and treatment of this condition.

Abstract
INTRODUCTION Cytokines and vascular endothelial growth factors (VEGF) are involved in all aspects of pregnancy: from placentation, through fetal development, parturition and neonatal well-being. Umbilical cord inflammatory cytokines and/or VEGF have not been well studied with respect to dysregulation associated with disorders of pregnancy or maternal/neonatal outcomes. METHODS Here we have used multiplex ELISA to screen umbilical cord lysates (comprising cord blood, endothelia and Wharton's jelly, n = 380), for levels of IFN-γ, IL1-β, IL-6, IL-8, IL-10, TNF-α and VEGFs A, C and D and associations with 46 ICD9/10 codes encompassing obstetric, maternal and neonatal variables. RESULTS No significant differences were observed for IFNγ, VEGFC or VEGFD with any clinical outcomes. The cytokines IL1-β, IL-6, IL-8, IL-10, and TNF-α showed varying levels of induction and suppression with primarily fetal-placental and neonatal complications. The largest number of significant differences between umbilical cytokines and clinical outcomes were observed for chorioamnionitis (IL1-β, IL-6, IL-8, TNF-α), and meconium passage during birth (IL1-β, IL-6, IL-8) where significant pro-inflammatory responses occurred and sex differences in IL-8 expression were noted. In contrast, gonococcal infection showed suppressed immune response significantly lowering IL1-β, IL-6, IL-8, IL-10 and TNF-α. For 12/46 negative pregnancy outcomes, strong suppression of VEGFA occurred. DISCUSSION Angiogenic and inflammatory changes in the umbilical cord could be detrimental by increasing vascular permeability in the umbilical artery or vein and/or altering vascular tone, either of which would alter blood flow affecting delivery and removal of compounds. Further elucidation of inflammatory responses in the umbilical cord may provide mechanistic understanding of adverse pregnancy outcomes.

Abstract
BACKGROUND The literature on brain imaging in premature infants is mostly made up of studies that evaluate neonates, yet the most dynamic time of brain development happens from birth to 1 year of age. This study was designed to obtain quantitative brain measures from magnetic resonance imaging scans of infants born prematurely at 12 months of age. METHODS The subject group was designed to capture a wide range of gestational age (GA) from premature to full-term infants. An age-specific atlas generated quantitative brain measures. A regression model was used to predict effects of GA and sex on brain measures. RESULTS There was a primary effect of sex on: (1) intracranial volume, males > females; (2) proportional cerebral cortical gray matter (females > males), and (3) cerebral white matter (males > females). GA predicted cerebral volume and cerebral spinal fluid. GA also predicted cortical gray matter in a sex-specific manner with GA having a significant effect on cortical volume in the males, but not in females. CONCLUSIONS AND RELEVANCE Sex differences in brain structure are large early in life. GA had sex-specific effects highlighting the importance evaluating sex effects in neurodevelopmental outcomes of premature infants.
