[PMID: 38115287 PMCID: PMC10727612 DOI: 10.1097/md.0000000000036557] [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: 05/20/2023] [Revised: 10/26/2023] [Accepted: 11/17/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND Retinopathy of prematurity (ROP) increases with the survival of late preterm infants, but its relationship with neurodevelopmental outcomes in preterm infants remains controversial. To investigate the relationship between ROP and its severity and adverse neurodevelopmental outcomes in preterm infants. METHODS We conducted a meta-analysis. All relevant literature before November 2022 were retrieved from PubMed, Embase, Cochrane Library Web of Science, CNKI, CBM, Wan fang Data, and VIP Database. According to the inclusion criteria and exclusion criteria, eligible literature were included to conduct clinical trial quality assessment, and the Newcastle-Ottawa scale was used to evaluate the quality of evidence. Meta-analysis was performed using RevMan5.3. Data extraction, quality assessment, and meta-analysis were performed independently by 2 people. Mean difference or standardized mean difference of motor, language and cognitive scores (Bayley III or Bayley II) were used as effect sizes for continuous data analysis, all of which were represented by 95% CI. For heterogeneity (I2 ≥ 50% or P < .10), a random effects model was used, otherwise a fixed effects model was used. RESULTS A total of 6 literature were included. The results of the ROP group for motor (comprehensive motor, proportional motor, and fine motor), language and cognitive scores were -5.57 (95%CI, -1.43 to 0.04), -0.95 (95%CI, 1.4-0.50), -1.34 (95% CI, 1.77-0.92), -1.75 (95% CI, 2.26-1.24) and -5.56 (95% CI, 9.56-1.57). Additionally, the results of severe ROP group for motor (comprehensive motor, proportional motor, fine motor), language and cognitive scores were -8.32 (95%CI, -8.91 to 7.74), -1.10 (95%CI, -1.83 to -0.36), -1.08 (95%CI, -1.75 to -0.41), -7.03 (95%CI, -7.71 to 6.35), and -7.96 (95%CI, -8.5 to -7.42). CONCLUSIONS The Bayley Scale scores of the ROP group were lower than those of the not ROP group, and the scores of the severe ROP were significantly lower than those of the not severe ROP group. These findings suggest that ROP can indeed delay motor, language and cognitive, especially in severe cases.

Gauthier-Moulinier H, Ndour D, Rabilloud M, Nguyen KA. Outcomes of pregnancies with preterm premature rupture of membranes occurring before 24 weeks of gestation: An 11-year observational study. Int J Gynaecol Obstet 2023. [PMID: 36707064 DOI: 10.1002/ijgo.14700] [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: 06/18/2022] [Revised: 01/06/2023] [Accepted: 01/26/2023] [Indexed: 01/29/2023]
Abstract
OBJECTIVE This study describes the fetal and neonatal outcomes and their predictive factors in pregnancies with preterm premature rupture of membranes (PPROM) before 24 weeks of gestation. METHODS A retrospective study was conducted using the patient database of a tertiary university hospital in Lyon, France. All of the medical data of women diagnosed with PPROM before 24 weeks of gestation from 2008 to 2018 were extracted. R software was used for descriptive and analytical statistics. RESULTS The study included 78 women. Mean gestational age (GA) at PPROM was 19.6 weeks (13.1 to 23.9 weeks). Fifteen (19.2%) pregnancies were terminated, 37 (47.4%) resulted in intrauterine fetal death (IUFD), and 26 (33.3%) children were born alive at an average of 26.9 weeks of gestation. Fourteen children survived and 12 died after birth; 50% of survivors had pulmonary hypoplasia. Within 7 days after PPROM, 46% of IUFD occurred and 36% of pregnancies ended. PPROM before 20 weeks of gestation and chorioamnionitis are statistically associated with IUFD, whereas a latency period of more than 2 weeks is statistically related to live birth. CONCLUSION PPROM before 24 weeks of gestation is associated with a high rate of IUFD, preterm birth, and postpartum mortality.

In the grey zone-survival and morbidities of periviable births. J Perinatol 2022; 42:1001-1007. [PMID: 35273353 DOI: 10.1038/s41372-022-01355-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 01/03/2022] [Accepted: 02/11/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVE To compare the survival and morbidities of infants born between 22 0/7-25 6/7 weeks of gestation. STUDY DESIGN This observational cohort study consisted of 187 eligible infants liveborn at a single, Level III Neonatal Intensive Care Unit (NICU) between June 1, 2009, and December 31, 2016, in Cleveland, Ohio. Infants with recognized syndromes or major congenital malformations were excluded from the review. RESULT The rate of survival to discharge for NICU-admitted infants born at 22- and 23- week was 56% and 54% respectively at our institution. There was no trend observed between gestational ages and incidence of necrotizing enterocolitis (NEC), patent ductus arteriousus (PDA), sepsis, or severe intraventricular hemorrhage (IVH- Grade 3 or 4). The infants born at 22 weeks had a higher incidence of retinopathy of prematurity (ROP) as compared to 25 weeks gestation (p < 0.001). The need for home oxygen was significantly higher in the smallest infants 70% at 22 weeks, 62% and 60% at 23 and 24 weeks versus 33% at 25 weeks gestation (p < 0.007). Those born at 22 weeks had the same rate of survival to discharge with severe IVH as those born at 23 weeks but required fewer VP shunts (p > 0.52). CONCLUSIONS The course of extremely preterm infants shows no difference between those born at 22 and 23 weeks of gestation in our NICU with regards to both mortality and short-term morbidities, although they differed marginally from 24 week gestation infants and significantly from those born at 25 weeks gestation.

Abstract
OBJECTIVE To compare mortality and rates of significant neurosensory impairment (sNSI) at 18-36 months' corrected age in infants born extremely preterm across three international cohorts. DESIGN Retrospective analysis of prospectively collected neonatal and follow-up data. SETTING Three population-based observational cohort studies: the Australian and New Zealand Neonatal Network (ANZNN), the Canadian Neonatal and Follow-up Networks (CNN/CNFUN) and the French cohort Etude (Epidémiologique sur les Petits Ages Gestationnels: EPIPAGE-2). PATIENTS Extremely preterm neonates of <28 weeks' gestation in year 2011. MAIN OUTCOME MEASURES Primary outcome was composite of mortality or sNSI defined by cerebral palsy with no independent walking, disabling hearing loss and bilateral blindness. RESULTS Overall, 3055 infants (ANZNN n=960, CNN/CNFUN n=1019, EPIPAGE-2 n=1076) were included in the study. Primary composite outcome rates were 21.3%, 20.6% and 28.4%; mortality rates were 18.7%, 17.4% and 26.3%; and rates of sNSI among survivors were 4.3%, 5.3% and 3.3% for ANZNN, CNN/CNFUN and EPIPAGE-2, respectively. Adjusted for gestational age and multiple births, EPIPAGE-2 had higher odds of composite outcome compared with ANZNN (OR 1.71, 95% CI 1.38 to 2.13) and CNN/CNFUN (OR 1.72, 95% CI 1.39 to 2.12). EPIPAGE-2 did have a trend of lower odds of sNDI but far short of compensating for the significant increase in mortality odds. These differences may be related to variations in perinatal approach and practices (and not to differences in infants' baseline characteristics). CONCLUSIONS Composite outcome of mortality or sNSI for extremely preterm infants differed across high-income countries with similar baseline characteristics and access to healthcare.

Current attitudes and beliefs toward perinatal care orientation before 25 weeks of gestation: The French perspective in 2020. Semin Perinatol 2022; 46:151533.

Abstract
The survival rate of infants born before 25 weeks of gestational age in France is extremely low compared with that of many other countries: 0%, 1%, and 31% at 22, 23, and 24 weeks' in the last national cohort study. A non-optimal regionalization and variations in practice are prevalent. Some parents in social media and support groups have reported feeling lost and confused with mixed messages leading to lack of trust. These data kindled a major debate in France around perinatal management leading to an investigation exploring neonatologists' perspectives and ways to improve care. The majority (81%) of the responding neonatologists reported more active care and higher survival rates than in 2011, although others continued preferring delivery room comfort care and limited NICU treatment at or before 24 weeks. The desire to improve was an overarching theme in all the respondents' answers to open-ended questions. Barriers to active care included an absence of expertise and of benchmarking to guide optimal care, and limited resources in the NICU and during follow-up - all leading to self-fulfilling prophecies of poor prognosis. Optimization of regionalization, perinatal teamwork and parental involvement, fostering experience by creating specific perinatal centers, stimulating benchmarking, and working with policy makers to allow better long-term outcomes could enable higher survival.

Front Pediatr 2022; 10:977422. [PMID: 36061390 PMCID: PMC9433924 DOI: 10.3389/fped.2022.977422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 08/01/2022] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVES The evidence that risks of morbidity and mortality are higher when very premature newborns are born during the on-call period is inconsistent. This study aimed to assess the impact of this situation among other determinants of outcomes, particularly newborn characteristics and care organization. METHODS Observational study including all infants born < 30 weeks' gestation in a French tertiary perinatal center between 2007 and 2020. On-call period corresponded to weekdays between 6:30 p.m. and 8:30 a.m., weekends, and public holidays. The primary endpoint was survival without severe morbidity, including grade 3-4 intraventricular hemorrhage (IVH), cystic periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia (BPD), and severe retinopathy of prematurity. The relationship between admission and outcome was assessed by an adjusted odds ratio (aOR) on the propensity of being born during on-call period and expressed vs. weekday. Secondary analyses were carried out in extremely preterm newborns (<27 weeks' gestation), in cases of early death (within 7 days), and before (2007-2013, 51.5% of the cohort) vs. after (2014-2020, 48.5% of the cohort) the implementation of a pediatrician-nurse team dedicated to newborn care in the delivery room. RESULTS A total of 1,064 infants [27.9 (26.3; 28.9) weeks, 947 (760; 1,147) g] were included: 668 during the on-call period (63%) and 396 (37%) on weekdays. For infants born on weekdays, survival without severe morbidity was 54.5% and mortality 19.2%. During on-call, these rates were 57.3% [aOR 1.08 (0.84-1.40)] and 18.4% [aOR 0.93 (0.67-1.29)]. Comparable rates of survival without severe morbidity [aOR 1.42 (0.87-2.34)] or mortality [aOR 0.76 (0.47-1.22)] were observed in extremely preterm infants. The early death rate was 6.4% on weekdays vs. 8.2% during on-call [aOR 1.44 (0.84-2.48)]. Implementation of the dedicated team was associated with decreased rates of mortality [aOR 0.57 (0.38, 0.85)] and grade 3-4 IVH [aOR 0.48 (0.30, 0.75)], and an increased rate of severe BPD [aOR 2.16 (1.37, 3.41)], for infants born during on-call. CONCLUSION In this cohort, most births of very premature neonates occurred during the on-call period. A team dedicated to newborn care in the delivery room may have a favorable effect on the outcome of infants born in this situation.

Abstract
OBJECTIVE To assess the association between time of birth and mortality among preterm infants. STUDY DESIGN Population-based study of infants born 22-36 weeks gestation (GA) in Canada from 2010 to 2015 (n = 173 789). Multivariable logistic regression models assessed associations between timing of birth and mortality. RESULT Among infants 22-27 weeks GA, evening birth was associated with higher mortality than daytime birth (adjusted odds ratio [AOR] 1.14, 95% CI 1.01-1.29). Among infants 28-32 weeks GA and 33-36 weeks GA, night birth was associated with lower mortality than daytime birth (AOR 0.75, 95% CI 0.59-0.95; AOR 0.78, 95% CI 0.62-0.99, respectively). Sensitivity analysis excluding infants with major congenital anomaly revealed that associations between hour of birth and mortality among infants born 28-32 and 33-36 weeks GA decreased or were not statistically significant. CONCLUSION Higher mortality among extremely preterm infants during off-peak hours may suggest variations in available resources based on time of day.

Abstract
OBJECTIVES To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications. METHODS The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants. RESULTS A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25+6 weeks, 26-26+6 weeks, 27-27+6 weeks, 28-28+6 weeks, 29-29+6 weeks, 30-30+6 weeks, and 31-31+6 weeks had a survival rate of 32.5%, 60.6%, 68.0%, 82.9%, 90.1%, 92.3%, and 94.8% respectively. The survival rate tended to increase with the gestational age (P<0.05) and the survival rate without serious complications in each gestational age group was 7.5%, 18.1%, 34.5%, 52.2%, 66.7%, 75.7%, and 81.8% respectively, suggesting that the survival rate without serious complications increased with the gestational age (P<0.05). The multivariate logistic regression analysis showed that high gestational age, high birth weight, and prenatal use of glucocorticoids were protective factors against death in very preterm infants (P<0.05), and 1-minute Apgar score ≤3 was a risk factor for death in very preterm infants (P<0.05); high gestational age and high birth weight were protective factors against serious complications in very preterm infants who survived (P<0.05), while 5-minute Apgar score ≤3 and maternal chorioamnionitis were risk factors for serious complications in very preterm infants who survived (P<0.05). CONCLUSIONS The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.
