Temporal Trend and Risk Factors for Respiratory Distress Syndrome-Associated Neonatal Mortality in Preterm Infants: A Population-Based Study in a Middle-Income Country. Am J Perinatol 2024; 41:e298-e304. [PMID: 35973740 PMCID: PMC11093649 DOI: 10.1055/s-0042-1754410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Accepted: 06/01/2022] [Indexed: 11/01/2022]
Abstract
OBJECTIVE This article aimed to report a temporal series of respiratory distress syndrome (RDS)-associated neonatal mortality rates in preterm live births in São Paulo state, Brazil, and to identify social, maternal, and neonatal characteristics associated with these deaths. STUDY DESIGN This is a population-based study of all live births with gestational age (GA) between 22 and 36 weeks, birth weight ≥400 g, without congenital anomalies from mothers living in São Paulo state during 2004 to 2015. RDS-associated neonatal mortality was defined as death up to 27 days after birth with ICD-10 codes P22.0 or P28.0. RDS-associated neonatal mortality rate (annual percent change [APC] with 95% confidence intervals [95% CIs]) was analyzed by Prais-Winsten. Kaplan-Meier estimator identified the time after birth that the RDS-associated neonatal death occurred. Poisson's regression model compared social maternal and neonatal characteristics between preterm live births that survived the neonatal period and those with RDS-associated neonatal deaths, with results expressed in incidence rate ratio and 95% CI. RESULTS A total of 645,276 preterm live births were included in the study, of which 612,110 survived and 11,078 had RDS-associated neonatal deaths. RDS-associated neonatal mortality rate was 17.17 per thousand preterm live births, with a decreasing annual trend (APC: -6.50%; 95% CI: -9.11 to -3.82%). The median time of these deaths was 48 hours after birth. The following risk factors for RDS-associated neonatal death were identified: maternal schooling ≤7 years (1.18; 1.09-1.29), zero to three prenatal care visits (1.25; 1.18-1.32), multiple pregnancy (1.24; 1.16-1.33), vaginal delivery (1.29; 1.22-1.36), GA 22 to 27 weeks (106.35; 98.36-114.98), GA 28 to 31 weeks (20.12; 18.62-21.73), male sex (1.16; 1.10-1.22), and 5-minute Apgar scores of 0 to 3 (6.74; 6.08-7.47) and 4 to 6 (3.97; 3.72-4.23). CONCLUSION During the study period, RDS-associated neonatal mortality rates showed significant reduction. The relationship between RDS-associated neonatal deaths and social, maternal, and neonatal factors suggests the need for perinatal strategies to reduce prematurity and to improve the initial management of preterm infants. KEY POINTS · RDS is associated with preterm live births.. · Impact of RDS-associated neonatal mortality in middle-income countries is scarce.. · Qualified perinatal care can reduce RDS-associated neonatal mortality..

Association of mode of delivery with short-term and neurodevelopmental outcomes in periviable singleton infants: A nationwide database study. Int J Gynaecol Obstet 2023; 163:307-314. [PMID: 37170688 DOI: 10.1002/ijgo.14833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 04/01/2023] [Accepted: 04/17/2023] [Indexed: 05/13/2023]
Abstract
OBJECTIVE To evaluate the association of mode of delivery (MOD) with short-term and neurodevelopmental outcomes at 2 years of corrected age (CA) in periviable singleton infants. METHODS This retrospective cohort study of the Taiwan Premature Infant Follow-up Network database between 2010 and 2016 compared non-anomalous singleton deliveries (cesarean delivery [CD] vs vaginal delivery [VD]) between 22 0/7 and 25 6/7 gestational weeks. Major morbidities, mortality, and neurodevelopmental outcomes were evaluated at 2-year CA. RESULTS The CD and VD groups included 354 and 472 infants, respectively. The intraventricular hemorrhage (IVH) rate was lower in the CD group (54% vs 66%, P = 0.001), but severe IVH differed non-significantly between groups (20% vs 26%, P = 0.057). In the small-for-gestational age subgroup, CD was associated with lower IVH (56% vs 84%, adjusted odds ratio [aOR] 0.17, 95% confidence interval [CI] 0.04-0.69) and better survival without neurodevelopmental impairment (29% vs 8%, aOR, 6.64, 95% CI 1.02-43.29) after controlling for potential confounders. CONCLUSION The optimal MOD for periviable singleton birth and its impact are unclear. CD in periviable singleton births is associated with a decreased IVH risk, without improvement in severe IVH, mortality, or neurodevelopment at 2-year CA. The small-for-gestational age subgroup may benefit from CD for better survival without neurodevelopmental impairment.

A Global Perspective on PDA Management in the Extremely Premature: Shifting Trend Toward Transcatheter Closure. JOURNAL OF THE SOCIETY FOR CARDIOVASCULAR ANGIOGRAPHY & INTERVENTIONS 2023; 2:100968. [PMID: 39131651 PMCID: PMC11307882 DOI: 10.1016/j.jscai.2023.100968] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/17/2023] [Accepted: 03/20/2023] [Indexed: 08/13/2024]
Abstract
Patent ductus arteriosus (PDA) is a frequently encountered defect in infants born extremely premature (≤26 weeks' gestation). Historically, closure of the PDA was performed using cyclooxygenase inhibitor medications or by surgical ligations. However, the benefits of PDA closure using these therapies have never been demonstrated, albeit studies have previously not focused on the extremely premature infants. Therefore, there was a worldwide trend toward conservative management of the PDA. With improved survival of extremely premature infants, comorbidities associated with the PDA has increased, resulting in finding alternate treatments such as transcatheter patent ductus arteriosus closure (TCPC) for this population. Currently, there is a renewed interest toward selective treatment of the PDA in this high-risk cohort of small infants. This Comprehensive Review article inspects the globally changing trends in the management of the PDA in premature infants, with a special focus on the rising adoption of TCPC. Moreover, this article compiles data from several neonatal networks worldwide to help understand the problem at hand. Understanding the current management of premature infants and their outcomes is fundamentally essential if pediatric cardiologists are to offer TCPC as a viable therapeutic option for this population. This article aims to serve as a guide for pediatric cardiologists on this topic by compiling the results on landmark clinical trials on PDA management and the controversies that arise from these trials. Comparative outcomes from several countries are presented, including interpretations and opinions of the data from experts globally. This is a step toward coming to a global consensus in PDA management in premature infants.

Risk Factors of Language Delay at Two Years of Corrected Age among Very-Low-Birth-Weight Preterm Infants: A Population-Based Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10020189. [PMID: 36832318 PMCID: PMC9955016 DOI: 10.3390/children10020189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/13/2023] [Accepted: 01/18/2023] [Indexed: 01/21/2023]
Abstract
Language delays are often underestimated in very-low-birth-weight (VLBW) preterm infants. We aimed to identify the risk factors of language delay at two years of corrected age in this vulnerable population. VLBW infants, who were assessed at two years of corrected age using the Bayley Scale of Infant Development, third edition, were included using a population-based cohort database. Language delay was defined as mild to moderate if the composite score was between 70 and 85 and severe if the score was < 70. Multivariable logistic regression analysis was used to identify the perinatal risk factors associated with language delay. The study comprised 3797 VLBW preterm infants; 678 (18%) had a mild to moderate delay and 235 (6%) had a severe delay. After adjusting for confounding factors, low maternal education level, low maternal socioeconomic status, extremely low birth weight, male sex, and severe intraventricular hemorrhage (IVH) and/or cystic periventricular leukomalacia (PVL) were found to be significantly associated with both mild to moderate and severe delays. Resuscitation at delivery, necrotizing enterocolitis, and patent ductus arteriosus requiring ligation showed significant associations with severe delay. The strongest factors predicting both mild to moderate and severe language delays were the male sex and severe IVH and/or cystic PVL; thus, early targeted intervention is warranted in these populations.

Abstract
BACKGROUND/PURPOSE The in-hospital length of stay (LOS) among very-low-birth-weight (VLBW, BW < 1500 g) infants is an index for care quality and affects medical resource allocation. We aimed to analyze the LOS among VLBW infants in Taiwan, and to develop and compare the performance of different LOS prediction models using machine learning (ML) techniques. METHODS This retrospective study illustrated LOS data from VLBW infants born between 2016 and 2018 registered in the Taiwan Neonatal Network. Among infants discharged alive, continuous variables (LOS or postmenstrual age, PMA) and categorical variables (late and non-late discharge group) were used as outcome variables to build prediction models. We used 21 early neonatal variables and six algorithms. The performance was compared using the coefficient of determination (R2) for continuous variables and area under the curve (AUC) for categorical variables. RESULTS A total of 3519 VLBW infants were included to illustrate the profile of LOS. We found 59% of mortalities occurred within the first 7 days after birth. The median of LOS among surviving and deceased infants was 62 days and 5 days. For the ML prediction models, 2940 infants were enrolled. Prediction of LOS or PMA had R2 values less than 0.6. Among the prediction models for prolonged LOS, the logistic regression (ROC: 0.724) and random forest (ROC: 0.712) approach had better performance. CONCLUSION We provide a benchmark of LOS among VLBW infants in each gestational age group in Taiwan. ML technique can improve the accuracy of the prediction model of prolonged LOS of VLBW.

Abstract
BACKGROUND Most previous studies reported there were higher survival rates if low birth weight babies were born in tertiary perinatal centers (inborn) than elsewhere (outborn). The objective of this study is to examine whether the number and ratio of outborn babies decrease and the neonatal mortality differs between inborn and outborn babies. METHODS We used the pooled data of the Taiwan Clinical Effectiveness Index for the years 2011-2016 obtained from the Joint Commission of Taiwan to study the outborn/inborn number and neonatal mortality rate. RESULTS We found that the number of outborn babies did not decrease year by year. The ratio of outborn to total babies was lower in the groups of birth body weight 750-999 g and ≧ 2500 g than the other groups. The neonatal mortality rate in outborns was significantly higher than the inborns in the groups of birth body weight 1000-1499 g, 2000-2499 g and ≧ 2500 g (6.9 ± 2.4 vs. 3.8 ± 0.9, P = 0.009, 2.6 ± 0.6 vs. 0.6 ± 0.3, P = 0.002 and 1.52 ± 0.67 vs. 0.08 ± 0.02, P = 0.002, respectively) in medical centers. CONCLUSION Improved maternal transport which promotes in utero transfer of patients may further improve neonatal outcome.

Abstract
BACKGROUND/PURPOSE To analyze the amount of variation in these risk-adjusted adverse outcomes corresponding to the care of premature births. In addition, hospitals were ranked according to their unadjusted and adjusted rates, and we assessed the degree of concordance between these rankings. Finally, the correlations of hospital-adjusted adverse outcomes were also tested. METHODS The study utilized the 5-year Taiwan Premature Infant Follow-up Network (TPFN) database in Taiwan from 2014 to 2018, and the sample size was 6482. We calculated the "observed over expected" (OE) ratio every year to form the risk-adjusted adverse outcome rate for each hospital. RESULTS There was a larger variation in the risk-adjusted rate for NEC and the second-largest variation for IVH. Regarding the concordances between the unadjusted and adjusted ranks, the ranks for mortality had the lowest concordance (coefficient of concordance 0.64), and only a few of the risk-adjusted rates between outcomes were significantly correlated. CONCLUSION The results of the TPFN show that there is room to improve performance in terms of large variations in NEC and IVH. Furthermore, risk adjustment is important, especially for mortality, since the ranks for mortality have the lowest concordance. Finally, we cannot generate a conclusion regarding whether a hospital is high in quality if we only take 1 or 2 adverse outcomes as profiling measures because only a few of the risk-adjusted rates between outcomes were significantly correlated.

Abstract
OBJECTIVE To study the effect of oral motor intervention (OMI) on brain function development in preterm infants. METHODS A total of 112 preterm infants were stratified into small-gestational-age (30-31+6 weeks) and large-gestational-age (32-33+6 weeks) according to gestational age at birth. The preterm infants were randomly divided into a control group and an intervention group, with 56 infants in each group. The infants in the control group were given routine treatment and nursing, while those in the intervention group were given OMI in addition to the treatment and nursing in the control group. Amplitude-integrated EEG (aEEG) and Neonatal Behavioral Neurological Assessment (NBNA) were performed on days 1, 7, and 14 of enrollment, and the level of brain function development was compared before and after intervention. RESULTS On day 7 of OMI, the small-gestational-age intervention group had lower upper bounds of voltage and bandwidth and a higher aEEG score than the small-gestational-age control group (P < 0.05). Compared with the small-gestational-age control group, the small-gestational-age intervention group had higher upper bound of voltage, percentage of mature sleep-wake cycle, aEEG score, and NBNA score and a lower narrow bandwidth on day 14 of OMI (P < 0.05). Compared with the large-gestational-age control group, the large-gestational-age intervention group had lower upper voltage and voltage difference and higher lower bound of voltage and aEEG score on days 7 and 14 of OMI (P < 0.05). On day 7 of OMI, the large-gestational-age intervention group had a higher NBNA score than the large-gestational-age control group (P < 0.05). CONCLUSIONS OMI can promote the maturation of aEEG background activities, improve neurobehavioral manifestations, and accelerate brain function development in preterm infants.

[PMID: 33478783 DOI: 10.1016/j.jfma.2020.12.025] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 12/04/2020] [Accepted: 12/24/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Using regression modeling analysis to investigate the breakpoints of the trends in survival-without-major-neonatal-morbidities (MNM) or -without-neurodevelopmental- impairment (NDI) by year and gestational age (GA) in preterm infants. METHODS We enrolled 2237 preterm infants (GA < 32 weeks) in Tainan, Taiwan. The trends in survival-without-MNM or -without-NDI by year (1995-2016) and GA (23-31 weeks), and the epochs and GA ranges with distinct changes were examined. Adjusted rate ratios (aRR) (95% confidence interval [CI]) were calculated using the rates in infants born at 23 weeks in 1995 as the reference. RESULTS For yearly trend, there were three epochs (1995-2000, 2001-2006, 2007-2016) with distinct changes in the rates of survival-without-MNM (aRR [95% CI] 1.07 [1.02-1.12], 1.04 [1.02-1.07], 1.02 [1.01-1.04]) and -without-NDI (1.03 [1.02-1.07], 1.02 [1.01-1.04], 1.01 [0.98-1.04]). For GA trend, the three GA ranges with different increases in the rates of survival-without-MNM were 23+0-26+6 (1.60 [1.31-1.94]), 27+0-28+6 (1.24 [1.14-1.34]) and 29+0-31+6 weeks (1.17 [1.02-1.34]), while those in the rates of survival-without-NDI were 23+0-25+6 (1.14 [1.03-1.25]), 26+0-28+6 (1.06 [1.02-1.12]) and 29+0-31+6 weeks (1.04 [1.02-1.07]). The trends in survival-without-MNM and -without-NDI increased over years in infants with GA 25-31 but not < 25 weeks. CONCLUSION The yearly trends in survival-without-MNM and -without-NDI had steady increases from 1995 to 2016 with distinct changes in three epochs, and the GA trends also increased with different rates per week in three GA ranges. Infants with GA < 25 weeks did not improve on the rates of survival-without-MNM or -without-NDI per year from 1995 to 2016.

Improved Survival of Periviable Infants after Alteration of the Threshold of Viability by the Neonatal Resuscitation Program 2015. CHILDREN-BASEL 2021; 8:children8010023. [PMID: 33406755 PMCID: PMC7824697 DOI: 10.3390/children8010023] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 12/27/2020] [Accepted: 12/29/2020] [Indexed: 01/11/2023]
Abstract
Periviable infants (PIs) born at 22–25 weeks gestational age (wGA) have a variable survival rate (49.7–86.2%) among hospitals. One factor involved in this difference may be the definition of the threshold of viability. The American Academy of Pediatrics revised the neonatal resuscitation program in late 2015 (NRP 2015) and altered the threshold of viability from 23 to 22 wGA. The impact on the survival of PIs after the guideline alteration has seldom been discussed. Since 2016, the unit of this study has implemented the renewed guideline for PIs. We retrospectively reviewed and analyzed the survival and clinical variables of PIs before and after implementation of the guideline, which included a 10-year cohort in a single center in Taiwan. There were 168 PIs enrolled between 2010 and 2019 (Epoch-I, 2010–2015; Epoch-II, 2016–2019), after excluding those with congenital anomalies and parent-decided comfort care. Compared to those in Epoch-I, the PIs in Epoch-II had significantly higher odds ratios (2.602) (95% confidence interval: 1.170–5.789; p = 0.019) for survival. Younger gestational age, small size for gestational age, cesarean delivery, low blood pH at birth, and surfactant therapeutic treatment were found to be significant risk factors associated with the survival of PIs (p < 0.05 for each). The altered threshold of viability by NRP 2015 may impact the survival of PIs. However, long-term follow-up for surviving PI is required in the future.

Predictive Validity of the Bayley-III Cognitive Scores at 6 Months for Cognitive Outcomes at 24 Months in Very-Low-Birth-Weight Infants. Front Pediatr 2021; 9:638449. [PMID: 34026684 PMCID: PMC8138438 DOI: 10.3389/fped.2021.638449] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 04/09/2021] [Indexed: 11/13/2022] Open
Abstract
Purpose: To assess the predictive validity of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) cognitive scores at 6 months of corrected age (CA) for cognitive outcomes at 24 months of CA in very-low-birth-weight (VLBW) infants and investigate the predictors of change in cognitive outcomes. Methods: We retrospectively evaluated VLBW children enrolled in the Taiwan Premature Infant Follow-up Network between 2010 and 2015 and completed the Bayley-III at CA of 6 and 24 months. The predictive validity of the cognitive performance at 6-month CA for the cognitive outcomes at 24-month CA was analyzed. The positive and negative predictive factors were also evaluated using logistic regression. Cut-off scores of <70 and <85 were used to identify lower functioning groups based on the Bayley-III definition. Results: A total of 2,972 VLBW children, born with a mean weight of 1116.4 ± 257.5 g and mean gestational age of 29.0 ± 2.8 weeks, were evaluated. A cognitive score of <70 at 6-month CA had a positive predictive value (PPV) of 27.4% (95% confidence interval [CI]: 19.2-35.7%) for a cognitive score of <70 at 24-month CA, while the negative predictive value (NPV) was 97.3% (95% CI: 96.7-97.9%). A cut-off score of 85 had a PPV of 33.6% (95% CI: 28.1-39.0%) and an NPV of 87.7% (95% CI: 86.4-88.9%). Abnormal muscle tone at 6 months was a risk factor for cognitive function decline at 24 months for both Bayley-III cognitive cut-off scores: scores of 70 (adjusted odds ratio [AOR]: 2.8; 95% CI: 1.5-5.5) and 85 (AOR: 2.6; 95% CI: 1.6-4.1). Lower maternal socioeconomic status was associated with a worsening of the cognitive function in infants at 24 months who scored ≥85 at 6 months (AOR: 1.6; 95% CI: 1.2-2.0). Conclusion: Subnormal Bayley-III cognitive scores at 6-month CA were not predictive of subnormal cognitive function at 24-month CA. In children with normal cognition during early infancy, abnormal muscle tone and lower maternal socioeconomic status may influence the cognitive developing process; this highlighted the importance of early identification of high risk infants and complete preterm infant-associated public health policies to promote an improved neurodevelopmental outcome.

Abstract
INTRODUCTION Despite the increase in the survival rate of high-risk infants (HRIs) worldwide, the prevalence of motor and neurodevelopmental sequelae in such newborns has not shown concomitant improvement. Meanwhile, there are few cohorts that explore factors related to the development of HRIs in China. Therefore, the Guangzhou High-Risk Infant Cohort (GHRIC) has been designed to examine the complex relationships among a myriad of factors influencing growth and development in such children. METHODS AND ANALYSIS The GHRIC study is a prospective cohort study that by the year 2023 will enrol an estimated total of 3000 HRIs from Guangzhou Women and Children's Medical Center (GWCMC) in Guangzhou, China. This study is designed to assess the growth and cognitive characteristics of HRIs and the risk factors affecting their development and prognoses. Data on risk factors, neurodevelopmental and cognitive-function evaluations, laboratory results, and specimens will be collected and analysed. Information on perinatal and clinical interventions for these infants will also be recorded during regular follow-up visits until age 6. ETHICS AND DISSEMINATION The protocol for this study has been approved by the Research Ethics Committee of GWCMC, which accepted responsibility for supervising all of the aspects of the study (No. 2017102712). Study outcomes will be disseminated through conference presentations, peer-reviewed publications, the Internet and social media. TRIAL REGISTRATION NUMBER ChiCTR-EOC-17013236.

Abstract
AIM Reports of the outcomes of infants born with marginal viability in developing countries are limited. This study aimed to determine the mortality rate and major disabilities of extremely preterm infants. METHODS A retrospective cohort with a prospective part of neurodevelopmental assessment was performed in infants born at 23-25+6 weeks' gestational age (GA) who received active resuscitation and were admitted to neonatal intensive care unit during 2005-2015. Surviving infants were recruited for neurodevelopmental assessment including cognition, gross motor and neurosensory disorders. Major disability was defined as one of the following: severe cognitive impairment, severe cerebral palsy, blindness or deafness. RESULTS A total of 67 infants were enrolled (8, 22 and 37 in the 23, 24 and 25 weeks' GA groups, respectively). The overall mortality rate before discharge was 26%. Infants in the 23 and 24 weeks' GA groups had a significantly higher mortality rate than did those in the 25 weeks' GA group (42 vs. 10%). Of 50 survivors (aged 2-12 years), 3 and 2 had blindness and deafness, respectively. Cognitive function assessment in 37 survivors showed that 4 (11%) and 15 (40%) had severe and borderline cognitive impairment, respectively. Death or major disability was found in 100, 63 and 38% in the 23, 24 and 25 weeks' GA groups, respectively. CONCLUSION In our centre, infants born at 23-24 weeks had a much higher chance of death or major disability than those born at 25 weeks' GA. Given such information, active management should be offered together with the family's involvement.

Abstract
BACKGROUND Neurodevelopmental outcome in preterm infants has been of great importance in recent decades. We determined the prevalence of abnormal neurodevelopmental outcomes and associated risk factors of very-low-birth-weight (VLBW) preterm infants at 2 and 5 years of age. METHODS We conducted a population-based, prospective cohort study of VLBW preterm infants born between 2002 and 2009 in Taiwan. Sociodemographic, neonatal data, and neurological assessments at 2 and 5 years of age were obtained from the database of Taiwan Premature Infant Follow-up Network. RESULTS Of the 6549 VLBW preterm infants included in the study, 5407 (82.56%) survived to discharge; 4105 and 1427 participated in follow-up assessments at age 2 and 5 years, respectively. At age 5 years, 76.87% (1097/1427), 12.05% (172/1427), and 8.76% (125/1427) of children had normal, borderline, and abnormal neurocognitive outcomes, separately. Among the enrolled children, 1385 were followed at both 2-year and 5-year-old. Among the 233 children with abnormal neurodevelopmental outcomes at age 5 years, nearly one-fifth (18.03%, 42/233) had normal or borderline neurodevelopmental outcomes at age 2 years. Among the 154 children with borderline neurodevelopmental outcomes at age 5 years, 71.43% (110/154) had normal or borderline neurodevelopmental outcomes at age 2 years. The risk factors significantly associated with disadvantageous (worsening or remaining unimproved) neurodevelopmental outcomes were lower gestational age, cystic periventricular leukomalacia, and paternal or maternal education ≤12 years. CONCLUSION Almost one-fifth of VLBW preterm children with abnormal neurodevelopmental outcomes at age 5 years had normal or borderline neurologic and developmental assessments at age 2 years. For the high risk group such as VLBW preterm children, serial follow-up assessments beyond 2 years of age may be warranted and the eligibility of early intervention service should be revised by the government so proper and targeted intervention can be implemented at earlier age.

Abstract
Sepsis is commonly experienced by infants born very preterm (<32 weeks gestational age and/or <1500 g birthweight), but the long-term functional outcomes are unclear. The objective of this systematic review was to identify observational studies comparing neurodevelopmental outcomes in very preterm infants who had blood culture-proven neonatal sepsis with those without sepsis. Twenty-four studies were identified, of which 19 used prespecified definitions of neurodevelopmental impairment and five reported neurodevelopmental outcomes as continuous variables. Meta-analysis was conducted using 14 studies with defined neurodevelopmental impairment and demonstrated that very preterm infants with neonatal sepsis were at higher risk of impairments, such as cerebral palsy and neurosensory deficits, compared with infants without sepsis (OR 3.18; 95% CI 2.29–4.41). Substantial heterogeneity existed across the studies (I2 = 83.1, 95% CI 73–89). The five studies that reported outcomes as continuous variables showed no significant difference in cognitive performance between sepsis and non-sepsis groups. Neonatal sepsis in very preterm infants is associated with increased risk of neurodevelopmental disability. Due to the paucity of longitudinal follow-up data beyond 36 months, the long-term cognitive effect of neonatal sepsis in very preterm infants could not be conclusively determined. Effects on the development of minor impairment could not be assessed, due to the small numbers of infants included in the studies.
