Abstract
Children born extremely preterm (EPT) or very preterm (VPT) are at risk of neurodevelopmental impairment. How the interaction between biological and social risk factors affects cognitive development has not yet been completely understood. The objectives of this study are to analyze and compare the language, memory, and learning outcomes of five-year-old children born EPT (<28 weeks' gestational age) and VPT (28-31+6 weeks' gestational age) and to determine the risk of having poor outcomes attending to perinatal and maternal characteristics. The analysis included 377 children born VPT (n = 284) and EPT (n = 93) in 2011-2012. Maternal, neonatal, and clinical information was obtained at birth, and maternal education was obtained at five years using a parental questionnaire. At five years, the language, memory, and learning outcomes were assessed with the developmental NEuroPSYchological assessment second edition (NEPSY-II®). Logistic regression models were applied to assess the association of biological and social risk factors with performance below the expected level for the child's age in language, memory, and learning subtests. Lower maternal age and education increased the odds of having language performance below the expected level for the child's age, while lower maternal educational level and gestational age increased the likelihood of having memory performance below the expected level. Children living in the most social disadvantage contexts are at a higher risk of suboptimal cognitive development. Implementing intervention programs in disadvantaged contexts and targeting specific cognitive domains may enable EPT and VPT children to reach and fulfill their potential in society.

Abstract
Many conditions may impair or delay language development, including socioeconomic status, parent's education, or intrauterine environment. Accordingly, increasing evidence has described that pregnancy complications, including gestational diabetes mellitus (GDM), preeclampsia, and preterm delivery, are associated with the offspring's impaired neurodevelopment. Since language is one of the high brain functions, alterations in this function are another sign of neurodevelopment impairment. How these maternal conditions may generate language impairment has yet to be entirely understood. However, since language development requires adequate structural formation and function/connectivity of the brain, these processes must be affected by alterations in maternal conditions. However, the underlying mechanisms of these structural alterations are largely unknown. This manuscript critically analyzes the literature focused on the risk of developing language impairment in children of mothers with GDM, preeclampsia, and preterm delivery. Furthermore, we highlight potential underlying molecular mechanisms associated with these alterations, such as neuroinflammatory and metabolic and cerebrovascular alterations.

Mesenchymal stem cell-derived secretomes for therapeutic potential of premature infant diseases. Biosci Rep 2021; 40:222738. [PMID: 32320046 PMCID: PMC7953482 DOI: 10.1042/bsr20200241] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 04/20/2020] [Accepted: 04/21/2020] [Indexed: 02/06/2023] Open
Abstract
Preterm birth is a complex syndrome and remains a substantial public health problem globally. Its common complications include periventricular leukomalacia (PVL), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC) and retinopathy of prematurity (ROP). Despite great advances in the comprehension of the pathogenesis and improvements in neonatal intensive care and associated medicine, preterm birth-related diseases remain essentially without adequate treatment and can lead to high morbidity and mortality. The therapeutic potential of mesenchymal stem/stromal cells (MSCs) appears promising as evidenced by their efficacy in preclinical models of pathologies relevant to premature infant complications. MSC-based therapeutic efficacy is closely associated with MSC secretomes and a subsequent paracrine action response to tissue injuries, which are complex and abundant in response to the local microenvironment. In the current review, we summarize the paracrine mechanisms of MSC secretomes underlying diverse preterm birth-related diseases, including PVL, BPD, NEC and ROP, are summarized, and focus is placed on MSC-conditioned media (CM) and MSC-derived extracellular vesicles (EVs) as key mediators of modulatory action, thereby providing new insights for future therapies in newborn medicine.

Tulviste T, Toome L, Männamaa M, Varendi H. Language skills at corrected age 2;0 are poorer in extremely and very preterm boys but not girls compared with their full-term peers. Early Hum Dev 2020; 151:105164. [PMID: 32866673 DOI: 10.1016/j.earlhumdev.2020.105164] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Revised: 08/18/2020] [Accepted: 08/19/2020] [Indexed: 12/25/2022]
Abstract
PURPOSE To date, there are contradictory findings concerning if, at which age, and to what extent children's language development is affected by prematurity at birth. The objective was to compare language skills of extremely preterm (EPT) and very preterm (VPT) girls and boys at 24 months corrected for gestational age (GA) at birth with those of full-term (FT) girls and boys, and to explore the effect of perinatal and demographic factors. METHOD Parents of 138 preterm (PT) children born <32 weeks' gestation (48 EPT with GA below 28 weeks, 90 VPT with GA 28-31 weeks) and of 150 FT controls completed the short Estonian version of the MacArthur-Bates Communicative Development Inventory: Words and Sentences (ECDI-II SF). Language skills of PT children were also assessed with the Bayley-III Language Scale (BSID-III), and compared with data from 152 FT controls. RESULTS Mean scores of all language measurements were significantly lower in boys (not girls) from both PT groups compared to FT girls and boys, while no significant differences were found between PT groups. Across groups, girls obtained significantly better language scores than boys. In PT children, being a girl, and attending day care at corrected age (CA) 2;0 years, predicted a larger expressive vocabulary (measured by the ECDI-II SF). Bayley language composite scores (sum of expressive and receptive language) were higher in PT girls than in boys, and the scores were negatively affected by the number of severe neonatal morbidities. CONCLUSIONS The findings highlight the importance of systematic language-focused assessments (using parents and trained examiners) of EPT and VPT boys, as well as the need to support their development.

Prospective Randomized Observational Pilot Trial Evaluating the Effect of Different Durations of Interdisciplinary Early Intervention and Family Support in Parents of Very Low Birth Weight Infants (Early Bird Study). Front Public Health 2020; 8:242. [PMID: 32719760 PMCID: PMC7349967 DOI: 10.3389/fpubh.2020.00242] [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: 12/17/2019] [Accepted: 05/19/2020] [Indexed: 01/05/2023] Open
Abstract
Background: Early childhood intervention (ECI) is a holistic approach for infants with or at risk for psychomotor and/or cognitive and/or behavioral impairment. It aims to optimally support them and positively influence their neurodevelopmental outcome. The right dosage of intervention and when the intervention should start are still to be determined. Hypothesis: Parents are more satisfied when the duration of ECI is longer (120 min once a week) than the usual 90-min session. Methods: We developed a parental questionnaire (both mother and father) that evaluated the level of satisfaction of parents with the intervention. We compared 120 with 90 min of ECI per week during the school year 2017/18. Included were parents of very low birth weight infants (<1,500 g) following informed consent. ECI was initiated at the NICU at an infant age of ≥ 2 weeks. Parents were randomized (https://www.randomizer.at/) to a 120- or 90-min duration and had to answer the questionnaire to the approximate time-point of 1, 3, and 6 months. Answers were classified as strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree except for the last question, which directly rated the ECI professional. Results: Eleven fathers (55%) and 19 mothers (95%) of the 10 parents of each group participated in the study. Demographic data did not differ between groups, and the median time-points of questionnaire answers were 77, 137, and 220 days, respectively. Overall, 120-min ECI sessions were not superior to 90-min sessions for both parents regarding parental satisfaction during the study time. We found no differences between fathers and mothers and minimal changes over time. All parents were satisfied with the ECI professionals, irrespective of ECI duration. Conclusion: An ECI duration of 120 min once per week was not superior to a 9- min duration regarding parental satisfaction with ECI professionals and their work.

Abstract
BACKGROUND The genomic contribution to adverse health sequelae in babies born very preterm (<32 weeks' gestation) is unknown. We conducted an investigation of rare CNVs in infants born very preterm as part of a study to determine the feasibility and acceptability of a larger, well-powered genome-wide investigation in the UK, with follow-up using linked National Health Service records and DNA storage for additional research. METHODS We studied 488 parent-offspring trios. We performed genotyping using Illumina Infinium OmniExpress Arrays. CNV calling and quality control (QC) were undertaken using published protocols. We examined de novo CNVs in infants and the rate of known pathogenic variants in infants, mothers and fathers and compared these with published comparator data. We defined rare pathogenic CNVs as those consistently reported to be associated with clinical phenotypes. RESULTS We identified 14 de novo CNVs, representing a mutation rate of 2.9%, compared with 2.1% reported in control populations. The median size of these CNV was much higher than in comparator data (717 kb vs 255 kb). The rate of pathogenic CNVs was 4.3% in infants, 2.7% in mothers and 2% in fathers, compared with 2.3% in UK Biobank participants. CONCLUSION Our findings suggest that the rate of de novo CNVs, especially rare pathogenic CNVs, could be elevated in those born very preterm. However, we will need to conduct a much larger study to corroborate this conclusion.
