[PMID: 39323403 DOI: 10.1542/peds.2024-065963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 06/11/2024] [Accepted: 06/12/2024] [Indexed: 09/27/2024] Open
Abstract
OBJECTIVE To provide contemporary data on infants inborn at 22 to 25 weeks' gestation and receiving care at level 3 and 4 neonatal intensive care units in the United States. METHODS Vermont Oxford Network members submitted data on infants born at 22 to 25 weeks' gestation at a hospital with a level 3 or 4 NICU from 2020 to 2022. The primary outcome was survival to hospital discharge. Secondary outcomes included survival without severe complications, length of stay, and technology dependence. RESULTS Overall, 22 953 infants at 636 US hospitals were included. Postnatal life support increased from 68.0% at 22 weeks to 99.8% at 25 weeks. The proportion of infants born at 22 weeks receiving postnatal life support increased from 61.6% in 2020 to 73.7% in 2022. For all infants, survival ranged from 24.9% at 22 weeks to 82.0% at 25 weeks. Among infants receiving postnatal life support, survival ranged from 35.4% at 22 weeks to 82.0% at 25 weeks. Survival without severe complications ranged from 6.3% at 22 weeks to 43.2% at 25 weeks. Median length of stay ranged from 160 days at 22 weeks to 110 days at 25 weeks. Among survivors, infants born at 22 weeks had higher rates of technology dependence at discharge home than infants born at later gestational ages. CONCLUSIONS Survival ranged from 24.9% at 22 weeks to 82.1% at 25 weeks, with low proportions of infants surviving without complications, prolonged lengths of hospital stay, and frequent technology dependence at all gestational ages.

Abstract
OBJECTIVES To elucidate the outcomes of periviable infants receiving active care (AC) and explore perinatal factors associated with neurodevelopmental outcomes. METHODS This is a single-center retrospective study on infants born at 22-25 weeks of gestation, all of whom received AC. A developmental quotient (DQ) ≥ 85 at corrected 18 months was judged as normal. RESULTS Fifty-seven infants were included in the study. The survival rates at discharge were 83%, 86%, 93%, and 93% at 22, 23, 24, and 25 gestational weeks, respectively. The overall percentage of normal DQ was 26/47 (55%). Acidemia in the arterial blood gas measured within 6 h after birth was identified as a factor significantly associated with subnormal DQ. CONCLUSIONS Not only high survival rates, but also favorable neurodevelopmental outcomes may be achieved by AC in periviable infants. Moreover, impaired neurodevelopmental outcomes may be associated with early postnatal acidemia following initial resuscitation.

Betamethasone treatment-to-delivery interval, retreatment, and severe intraventricular hemorrhage in infants <28 weeks' gestation. Am J Obstet Gynecol 2024:S0002-9378(24)00741-5. [PMID: 38971464 DOI: 10.1016/j.ajog.2024.06.048] [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: 04/16/2024] [Revised: 06/07/2024] [Accepted: 06/21/2024] [Indexed: 07/08/2024]
Abstract
BACKGROUND Antenatal corticosteroids decrease the incidence of severe intraventricular hemorrhage (grades 3, 4) in preterm infants. It is unclear whether their beneficial effects on intraventricular hemorrhage wane with time (as occurs in neonatal respiratory distress) and if repeat courses can restore this effect. Previous randomized controlled trials of betamethasone retreatment found no benefit on severe intraventricular hemorrhage rates. However, the trials may have included an insufficient number of infants at risk for intraventricular hemorrhage to be able to adequately address this question. Severe intraventricular hemorrhages occur almost exclusively in infants born at <28 weeks' gestation, whereas only 7% (0%-16%) of the retreatment trials' populations were <28 weeks' gestation. OBJECTIVE This study aimed to determine if the risk for severe intraventricular hemorrhage in infants delivered at <28 weeks' gestation increases when the betamethasone treatment-to-delivery interval increases beyond 9 days and to determine if betamethasone retreatment before delivery decreases the rate of hemorrhage. STUDY DESIGN This was an observational study that examined the incidence of intraventricular hemorrhage before (epoch 1) and after (epoch 2) a practice change that encouraged obstetricians to retreat pregnant women still at high risk for delivery before 28 weeks' gestation when >9 days elapsed from the first dose of betamethasone. Multivariable analyses with logistic regression using generalized estimating equation techniques were conducted to examine the rates of intraventricular hemorrhage among 410 infants <28 weeks' gestation who were either delivered between 1 to 9 days (n=290) after the first 2-dose betamethasone course or ≥10 days (and eligible for retreatment) after the first course (n=120). RESULTS After adjusting for potential confounding variables, infants who were delivered ≥10 days after a single betamethasone course had an increased risk for either severe intraventricular hemorrhage alone or the combined outcome severe intraventricular hemorrhage or death before 4 days (odds ratio, 2.8; 95% confidence interval, 1.2-6.6) when compared with infants who were delivered between 1 and 9 days after betamethasone. Among the 120 infants who were delivered ≥10 days after the first dose of betamethasone, 64 (53%) received a second or retreatment course of antenatal betamethasone. The severe intraventricular hemorrhage rate in infants whose mothers received a second or retreatment course of betamethasone was similar to the rate among infants who delivered within 1 to 9 days and significantly lower than among those who delivered ≥10 days without retreatment (odds ratio, 0.10; 95% confidence interval, 0.02-0.65). Following the change in guidelines, the rate of retreatment in infants who were delivered ≥10 days after the first betamethasone course (and before 28 weeks) increased from epoch 1 to epoch 2 (25% to 87%; P<.001) and the rate of severe intraventricular hemorrhage decreased from 22% to 0% (P<.001). In contrast, the rate of severe intraventricular hemorrhage among infants who were delivered 1 to 9 days after the initial betamethasone dose (who were not eligible for retreatment) did not change between epochs 1 and 2 (12% and 11%, respectively). CONCLUSION Although betamethasone's benefits on severe intraventricular hemorrhage appear to wane after the first dose, retreatment with a second course seems to restore its beneficial effects. Encouraging earlier retreatment of women at high risk for delivery before 28 weeks was associated with a lower rate of severe intraventricular hemorrhages among infants delivered at <28 weeks' gestation.

Abstract
OBJECTIVE To compare estimated healthcare resources needed to care for 22 through 24 weeks' gestation infants. STUDY DESIGN This multicenter, retrospective cohort study included 1505 live in-born and out-born infants 22 through 24 weeks' gestational age at delivery from 6 pediatric tertiary care hospitals from 2011 through 2020. Median neonatal intensive care unit (NICU) length of stay (LOS) for each gestational age was used as a proxy for hospital resource utilization, and the number of comorbidities and medical technology use for each infant were used as estimates of future medical care needs. Data were analyzed using Kruskal-Wallis with Nemenyi's posthoc test and Fisher's exact test. RESULTS Of the identified newborns, 22-week infants had shorter median LOS than their 23- and 24-week counterparts due to low survival rates. There was no significant difference in LOS for surviving 22-week infants compared with surviving 23-week infants. Surviving 22-week infants had similar proportions of comorbidities and medical technology use as 23-week infants. CONCLUSIONS Compared with 23- and 24-week infants, 22-week infants did not use a disproportionate amount of hospital resources. Twenty-two-week infants should not be excluded from resuscitation based on concern for increased hospital care and medical technology requirements. As overall resuscitation efforts and survival rates increase for 22-week infants, future research will be needed to assess the evolution of these results.

Abstract
OBJECTIVE The threshold of viability, as well as cutoffs for delivery interventions and neonatal resuscitation, vary by hospital and involve complex counseling. With improvements in neonatal resuscitation and intensive care, the threshold of viability has been decreasing. Decisions regarding delivery planning and neonatal resuscitation efforts should be based on the best available evidence. Our objective was to characterize survival rates and neonatal outcomes following periviable birth at different milestones beginning with prenatal admission through 1 year of life in a contemporary cohort. STUDY DESIGN We performed a retrospective cohort study of all inborn infants without major congenital anomalies who delivered at the University of Alabama at Birmingham from 2013 to 2019 at gestational ages 22+0/7 to 25+6/7. Our primary outcome was to compared survival milestones throughout the pre- and postdelivery periods and neonatal complications in surviving newborns through 1 year of life at each gestational age. RESULTS The survival rate to 1 year of life was 49% (48-56%, 95% confidence interval [CI]) for the entire cohort and varied according to gestational age at delivery (22 weeks 15% [10-23%, 95% CI], 23 weeks 48% [43-58%, 95% CI], 24 weeks 57% [52-67%, 95% CI], 25 weeks 71% [67-82%, 95% CI]). Overall for the entire cohort, the rate of lung disease requiring respiratory support at discharge was 51%, intraventricular hemorrhage was 42%, retinopathy of prematurity was 74%, pulmonary hypertension was 30%, and concerns for cerebral palsy at 1 year of life was 25%. All outcomes improved with advancing gestational age at delivery. Of infants who delivered during the 22nd week of gestation, 50% received antenatal corticosteroids. Infants exposed to antenatal corticosteroids had more interventions, less pulmonary hypertension, and improved survival to 1 year of life. CONCLUSION Knowledge of maternal complications, longitudinal survival rates, and neonatal outcomes of periviable deliveries according to gestational age throughout the admission enhances obstetric and perinatal counseling after hospital admission. KEY POINTS · Periviable birth outcomes at different delivery milestones is important for counseling.. · Providing contemporary outcomes for periviable deliveries is critical for accurate counseling.. · Administration of antenatal corticosteroids at 22 weeks' gestation appears beneficial overall..

[PMID: 38527604 DOI: 10.1016/j.ajog.2024.03.020] [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: 02/11/2024] [Revised: 03/18/2024] [Accepted: 03/18/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND In recent years, perinatal viability has shifted from 24 to 22 weeks of gestation at many institutions after improvements in survival in neonates delivered at the limit of viability. Monitoring these fetuses is essential because antenatal interventions with resuscitation efforts are available for patients at risk of delivery at the limit of viability. However, fetal monitoring using biophysical profiles has not been extensively studied in very preterm pregnancies, particularly in the periviable period (20 weeks 0 days to 23 weeks 6 days). OBJECTIVE This study aimed to (1) investigate whether the completion of biophysical profiles within 30 minutes is feasible in very preterm pregnancies, and (2) determine the average observation time required to achieve a score of 8 out of 8 in very preterm pregnancies from 20 weeks 0 days to 31 weeks 6 days. STUDY DESIGN This study prospectively evaluated biophysical scores in singleton pregnancies undergoing routine ultrasonography at or near viability from 20 weeks 0 days to 23 weeks 6 days (periviable or group I), 24 weeks 0 days to 27 weeks 6 days (group II), and 28 weeks 0 days to 31 weeks 6 days (group III). The results and duration of biophysical profiles were compared with those of a control group (32 weeks 0 days to 35 weeks 6 days) undergoing indicated fetal surveillance. Biophysical profiles were performed for all studied pregnancies until a score of 8 out of 8 was obtained. When >1 biophysical profile was obtained during pregnancy, each was analyzed individually. Pregnancies with fetal anomalies or obstetrical/medical indications for fetal well-being surveillance were excluded. Analysis of variance and post hoc Tukey tests were used for comparisons. RESULTS Data were collected for 123 participants, yielding 79, 75, and 72 studies for groups I, II, and III, respectively. The control group included 42 patients, yielding 140 studies. At 30 minutes, 80% (63/79) of the studies in the periviable group had a score of 8 out of 8, as opposed to 100% (140/140) in the control group (P<.001). The mean±standard deviation time in minutes to achieve a biophysical score of 8 out of 8 was 23.3±10.1 in the periviable group, as opposed to 9.4±6.5 in controls (P<.001). Extending the study to +2 standard deviations (43.6 minutes) in the periviable group resulted in 97% (77/79) of the scans scoring 8 out of 8 in the absence of adverse outcomes. In the other groups, a biophysical score of 8 out of 8 within 30 minutes was obtained in 97% (73/75) and 100% (72/72) in groups II and III, respectively; the mean±standard deviation times were 17.1±8.4 minutes (group II) and 13.1±7.3 minutes (group III). No adverse outcomes developed during the study participation in groups I to III. CONCLUSION Biophysical scores of 8 out of 8 can be successfully achieved in low-risk periviable pregnancies (20 weeks 0 days to 23 weeks 6 days) within an observation time longer than the standard 30-minute duration. The time required to reach a score of 8 out of 8 decreases as gestation progresses. We suggest adjusting the observation time for biophysical profile completion according to the gestational age.

Abstract
Importance During the past decade, clinical guidance about the provision of intensive care for infants born at 22 weeks' gestation has changed. The impact of these changes on neonatal intensive care unit (NICU) resource utilization is unknown. Objective To characterize recent trends in NICU resource utilization for infants born at 22 weeks' gestation compared with other extremely preterm infants (≤28 weeks' gestation) and other NICU-admitted infants. Design, Setting, and Participants This is a serial cross-sectional study of 137 continuously participating NICUs in 29 US states from January 1, 2008, through December 31, 2021. Participants included infants admitted to the NICU. Data analysis was performed from October 2022 to August 2023. Exposures Year and gestational age at birth. Main Outcomes and Measures Measures of resource utilization included NICU admissions, NICU bed-days, and ventilator-days. Results Of 825 112 infants admitted from 2008 to 2021, 60 944 were extremely preterm and 872 (466 [53.4%] male; 18 [2.1%] Asian; 318 [36.5%] Black non-Hispanic; 218 [25.0%] Hispanic; 232 [26.6%] White non-Hispanic; 86 [9.8%] other or unknown) were born at 22 weeks' gestation. NICU admissions at 22 weeks' gestation increased by 388%, from 5.7 per 1000 extremely preterm admissions in 2008 to 2009 to 27.8 per 1000 extremely preterm admissions in 2020 to 2021. The number of NICU admissions remained stable before the publication of updated clinical guidance in 2014 to 2016 and substantially increased thereafter. During the study period, bed-days for infants born at 22 weeks increased by 732%, from 2.5 per 1000 to 20.8 per 1000 extremely preterm NICU bed-days; ventilator-days increased by 946%, from 5.0 per 1000 to 52.3 per 1000 extremely preterm ventilator-days. The proportion of NICUs admitting infants born at 22 weeks increased from 22.6% to 45.3%. Increases in NICU resource utilization during the period were also observed for infants born at less than 22 and at 23 weeks but not for other gestational ages. In 2020 to 2021, infants born at less than or equal to 23 weeks' gestation comprised 1 in 117 NICU admissions, 1 in 34 of all NICU bed-days, and 1 in 6 of all ventilator-days. Conclusions and Relevance In this serial cross-sectional study of 137 US NICUs from 2008 to 2021, an increasing share of resources in US NICUs was allocated to infants born at 22 weeks' gestation, corresponding with changes in national clinical guidance.

Abstract
OBJECTIVE To describe changes over time in resuscitation, survival, and morbidity of extremely preterm infants in California. STUDY DESIGN This population-based, retrospective cohort study includes infants born ≤28 weeks. Linked birth certificates and hospital discharge records were used to evaluate active resuscitation, survival, and morbidity across two epochs (2011-2014, 2015-2019). RESULTS Of liveborn infants, 0.6% were born ≤28 weeks. Active resuscitation increased from 16.9% of 22-week infants to 98.1% of 25-week infants and increased over time in 22-, 23-, and 25-week infants (p-value ≤ 0.01). Among resuscitated infants, survival to discharge increased from 33.2% at 22 weeks to 96.1% at 28 weeks. Survival without major morbidity improved over time for 28-week infants (p-value < 0.01). CONCLUSION Among infants ≤28 weeks, resuscitation and survival increased with gestational age and morbidity decreased. Over time, active resuscitation of periviable infants and morbidity-free survival of 28-week infants increased. These trends may inform counseling around extremely preterm birth.

[PMID: 38328675 PMCID: PMC10846922 DOI: 10.1155/2024/3623948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/20/2023] [Accepted: 01/17/2024] [Indexed: 02/09/2024] Open
Abstract
Background KL-6 is a biomarker of interstitial lung injury and increases during repair. Aim Our aim was to determine the predictive value of plasma KL-6 for the development of bronchopulmonary dysplasia (BPD) in preterm infants. Methods Ninety-five extremely preterm infants (EPIs), born at <28 gestational age (GA), were divided into two main BPD groups as follows: the moderate/severe and the no/mild group. KL-6 was analyzed on days 7 and 14. Binary logistic regression analyses and ROC curve analyses were performed. Results Infants <26 + 0 weeks' GA have higher mean KL-6 than infants >25 + 6 weeks' GA on 7 and 14 days (335 vs. 286 U/ml and 378 vs. 260 U/ml; p = 0.005 and 0.018, respectively). In the binary regression model at KL-6 day 7, three of the prognostic factors remained significant-mechanical ventilation OR: 10.38 (95% CI: 3.57-30.14), PDA OR: 6.39 (95% CI: 0.87-46.74), and KL-6 OR: 4.98 (95% CI: 1.54-16.08). The AUC was 0.86 with a sensitivity and specificity of 79% at a cutoff value ≥0.34. In the binary regression model at KL-6 day 14, six of the prognostic factors were significant-PDA OR: 23.34 (95% CI: 2.14-254.24), KL-6 OR: 13.59 (95% CI: 3.19-57.96), GA OR: 4.58 (95% CI: 1.16-18.06), mechanical ventilation OR: 4.45 (95% CI: 1.23-16.16), antenatal steroids OR: 0.19 (95% CI: 0.04-0.95), and gender (female OR: 0.30 (95% CI 0.08-1.12)). The AUC was 0.91, and the sensitivity and accuracy for a cutoff ≥0.37 were 89% and 85%, respectively. Conclusion KL-6 could be a useful screening biomarker for early detection of infants at increased risk for developing BPD.

Abstract
Neonates born at the cusp of viability are at particularly high risk of severe morbidity and mortality. With advances in medicine and technology, the ability to resuscitate smaller, more premature neonates has become possible, and survival as early as 21 weeks of gestation has been reported. Although administration of antenatal corticosteroids has been shown to reduce the risk of morbidity and mortality at later gestational ages, neonates born before 24 weeks of gestation have not been included in randomized clinical trials. Changing clinical practices surrounding neonatal resuscitation with intervention offered after birth at earlier gestational ages has prompted re-evaluation of the use of antenatal corticosteroids at these very early gestational ages. Recent observational data demonstrate that antenatal corticosteroids administered before deliveries at or after 22 weeks of gestation are associated with lower risks of neonatal mortality, although survival with severe morbidity remains high. Future research is needed to determine the efficacy of antenatal corticosteroids for deliveries before 22 weeks of gestation and should evaluate the timing of corticosteroid administration. Furthermore, efforts should be made to include diverse populations and clinically meaningful long-term outcomes. At this time, the decision surrounding antenatal corticosteroids for threatened periviable deliveries should incorporate multidisciplinary counseling with the goal of achieving concordant prenatal and postnatal management aligned with the patient's desires.

Abstract
OBJECTIVE To explore associations between perinatal activity and survival in infants born at 22 and 23 weeks of gestation in Sweden. DESIGN/SETTING Data on all births at 22 and 23 weeks' gestational age (GA) were prospectively collected in 2004-2007 (T1) or obtained from national registers in 2014-2016 (T2) and 2017-2019 (T3). Infants were assigned perinatal activity scores based on 3 key obstetric and 4 neonatal interventions. MAIN OUTCOME One-year survival and survival without major neonatal morbidities (MNM): intraventricular haemorrhage grade 3-4, cystic periventricular leucomalacia, surgical necrotising enterocolitis, retinopathy of prematurity stage 3-5 or severe bronchopulmonary dysplasia. The association of GA-specific perinatal activity score and 1-year survival was also determined. RESULTS 977 infants (567 live births and 410 stillbirths) were included: 323 born in T1, 347 in T2 and 307 in T3. Among live-born infants, survival at 22 weeks was 5/49 (10%) in T1 and rose significantly to 29/74 (39%) in T2 and 31/80 (39%) in T3. Survival was not significantly different between epochs at 23 weeks (53%, 61% and 67%). Among survivors, the proportions without MNM in T1, T2 and T3 were 20%, 17% and 19% for 22 weeks and 17%, 25% and 25% for 23 weeks' infants (p>0.05 for all comparisons). Each 5-point increment in GA-specific perinatal activity score increased the odds for survival in first 12 hours of life (adjusted OR (aOR) 1.4; 95% CI 1.3 to 1.6) in addition to 1-year survival (aOR 1.2; 95% CI 1.1 to 1.3), and among live-born infants it was associated with increased survival without MNM (aOR 1.3; 95% CI 1.1 to 1.4). CONCLUSION Increased perinatal activity was associated with reduced mortality and increased chances of survival without MNM in infants born at 22 and 23 weeks of GA.

Abstract
OBJECTIVE In 2014, the leading obstetric societies published an executive summary of a joint workshop to establish obstetric interventions to be considered for periviable births. Antenatal corticosteroid administration between 220/7 and 226/7 weeks was not recommended given existing evidence. We sought to evaluate whether antenatal steroid exposure was associated with improved survival among resuscitated newborns delivered between 22 and 23 weeks of gestation. STUDY DESIGN We conducted a population-based cohort study of all resuscitated livebirths delivered between 220/7 and 236/7 weeks of gestation in the United States during 2009 to 2014 utilizing National Center for Health Statistics data. The primary outcome was rate of survival to 1 year of life (YOL) between infant cohorts based on antenatal steroid exposure. Multivariable logistic regression estimated the association of antenatal steroid exposure on survival outcomes. RESULTS In the United States between 2009 and 2014, there were 2,635 and 7,992 infants who received postnatal resuscitation after delivery between 220/7 to 226/7 and 230/7 to 236/7 weeks of gestation, respectively. Few infants born at 22 (15.9%) and 23 (26.0%) weeks of gestation received antenatal corticosteroids (ANCS). Among resuscitated neonates, survival to 1 YOL was 45.2 versus 27.8% (adjusted relative risk [aRR]: 1.6, 95% confidence interval [CI]: 1.2-2.1) and 57.9 versus 47.7% (aRR: 1.3, 95% CI: 1.1-1.5) for infants exposed to ANCS compared with those not exposed at 22 and 23 weeks of gestation, respectively. When stratified by 100 g birth weight category, ANCS were associated with survival among neonates weighing 500 to 599 g (aRR: 1.9, 95% CI: 1.3-2.9) and 600 to 699 g (aRR: 1.7, 95% CI: 1.1-2.6) at 22 weeks. CONCLUSION Exposure to ANCS was associated with higher survival rates to 1 YOL among resuscitated infants born at 22 and 23 weeks. National guidelines recommending against ANCS utilization at 22 weeks should be re-evaluated given emerging evidence of benefit. KEY POINTS · Exposure to antenatal steroids was associated with higher survival rates at 22 and 23 weeks of gestation.. · Women exposed to antenatal steroids were more likely to have an adverse outcome.. · The association between steroids and survival was observed among infants with birth weights > 500 g..

Abstract
OBJECTIVE We aimed to present the active management and outcomes of infants born at 22 weeks of gestation. STUDY DESIGN This retrospective observational study presented the resuscitation methods, management during hospitalization, and outcomes of 29 infants born at 22 weeks of gestation who were actively resuscitated and admitted to our center during 2013-2020. RESULTS The survival rate was 82.8% (24/29). Tracheal intubation was performed in all patients, and surfactant was administered for 27 (93.1%). Conventional mechanical ventilation was introduced in 27 (93.1%), and this was changed to high-frequency oscillatory ventilation in more than half by day 4. Surgical treatments of patent ductus arteriosus, necrotizing enterocolitis, and retinopathy of prematurity were required in 4 (13.7%), 3 (10.3%), and 15 (51.7%) patients, respectively. No patient required a tracheostomy or ventriculoperitoneal shunt. CONCLUSIONS The overall survival rate and survival rate without morbidities were high among infants born at 22 weeks of gestation.

Abstract
Preterm human infants often show periodic breathing (PB) or apnea of prematurity (AOP), breathing patterns which are accompanied by intermittent hypoxia (IH). We examined cause-effect relationships between transient IH and reduced facial bone growth using a rat model. Neonatal pups from 14 timed pregnant Sprague-Dawley rats were randomly assigned to an IH condition, with oxygen altering between 10% and 21% every 4 min for 1 h immediately after birth, or to a litter-matched control group. The IH pups were compared with their age- and sex-matched control groups in body weight (WT), size of facial bones and nor-epinephrine (NE) levels in blood at 3, 4, and 5-weeks. Markedly increased activity of osteoclasts in sub-condylar regions of 3-week-old IH-treated animals appeared, as well as increased numbers of sympathetic nerve endings in the same region of tissue sections. Male IH-pups showed significantly higher levels of NE levels in sera at 3, 4 as well as 5-week-old time points. NE levels in 4- and-5-week-old female pups did not differ significantly. Intercondylar Width, Mandible Length and Intermolar Width measures consistently declined after IH insults in 3- and 4-week-old male as well as female animals. Three-week-old male IH-pups only showed a significantly reduced (p < 0.05) body weight compared to those of 3-week controls. However, female IH-pups were heavier than age-matched controls at all 3 time-points. Trabecular bone configuration, size of facial bones, and metabolism are disturbed after an IH challenge 1 h immediately after birth. The findings raise the possibility that IH, introduced by breathing patterns such as PB or AOP, induce significantly impaired bone development and metabolic changes in human newborns. The enhanced NE outflow from IH exposure may serve a major role in deficient bone growth, and may affect bone and other tissue influenced by that elevation.

Abstract
INTRODUCTION Due to the extreme immaturity of many internal organs, including lungs, infants at the limit of viability are more predisposed to a pneumothorax (PTX). In some cases, PTX becomes persistent. Previously, only a few attempts of PTX treatment with fibrin glue were reported. However, its impact on further lung development is unknown. CASE REPORT We present a case of an extremely preterm infant with persistent PTX who was successfully treated with fibrin glue. In addition, we present a two-and-a-half-year corrected age follow-up focusing on respiratory problems, motor development and sensory organs. Furthermore, we touch upon the related ethical issues. CONCLUSIONS Fibrin glue should be used to treat persistent PTX even in an extremely preterm infant. No adverse effects were observed. At the two-and-a-half-year corrected age follow-up, despite severe bronchopulmonary dysplasia development, no serious pulmonary problems were observed. However, the child's development is uncertain. This situation raises important ethical issues concerning saving the lives of infants at the limit of viability.

Abstract
PURPOSE OF REVIEW To examine updated recommendations for obstetrical interventions that may improve neonatal outcomes in extremely preterm births. RECENT FINDINGS Several recent studies of antenatal steroids at the threshold of viability have demonstrated benefits in both survival and survival without major morbidity. This has led to revised recommendations from the American College of Obstetricians and Gynecologist regarding the timing of antenatal steroids in these extremely preterm fetuses. SUMMARY These recent developments have important implications for clinical care in patients at risk for extremely preterm birth based on a model of best practices and shared decision-making.

Active approach in delivery room and survival of infants born between 22 and 26 gestational weeks are increasing in Spain. Acta Paediatr 2023; 112:417-423. [PMID: 36515614 DOI: 10.1111/apa.16625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 12/08/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022]
Abstract
AIM To describe the trends in the delivery room approach and survival of extremely premature infants over the past two decades. METHODS Time-series analysis of infants included in the Spanish SEN1500 network from 2004 to 2019. Patients born from 22 + 0 to 26 + 6 weeks were included. The primary outcome was an active approach in the delivery room. Survival and temporal trends were also studied. RESULTS The study population included 8284 patients. At 22 and 23 weeks, an active approach was followed in 41.4% and 80.8%. A temporal trend toward a more active approach was observed at 23 weeks. Antenatal steroids were administered in 19.6% and 58.1% at 22 and 23 weeks. From 24 weeks, an active approach was applied in nearly all cases throughout the period, and more than 80% of patients received antenatal steroids. The rates of survival after an active approach were 8.7%, 21.6%, 40.6%, 59.9%, and 74.7% at 22, 23, 24, 25, and 26 weeks and significantly increased over the period, except for infants born at 22 weeks. CONCLUSION Active management and survival of infants born from 23 weeks increased over the period, but the frequency of antenatal steroid administration was lower than the intention to resuscitate.

Abstract
Respiratory distress syndrome (RDS) care pathways evolve slowly as new evidence emerges. We report the sixth version of "European Guidelines for the Management of RDS" by a panel of experienced European neonatologists and an expert perinatal obstetrician based on available literature up to end of 2022. Optimising outcome for babies with RDS includes prediction of risk of preterm delivery, appropriate maternal transfer to a perinatal centre, and appropriate and timely use of antenatal steroids. Evidence-based lung-protective management includes initiation of non-invasive respiratory support from birth, judicious use of oxygen, early surfactant administration, caffeine therapy, and avoidance of intubation and mechanical ventilation where possible. Methods of ongoing non-invasive respiratory support have been further refined and may help reduce chronic lung disease. As technology for delivering mechanical ventilation improves, the risk of causing lung injury should decrease, although minimising time spent on mechanical ventilation by targeted use of postnatal corticosteroids remains essential. The general care of infants with RDS is also reviewed, including emphasis on appropriate cardiovascular support and judicious use of antibiotics as being important determinants of best outcome. We would like to dedicate this guideline to the memory of Professor Henry Halliday who died on November 12, 2022.These updated guidelines contain evidence from recent Cochrane reviews and medical literature since 2019. Strength of evidence supporting recommendations has been evaluated using the GRADE system. There are changes to some of the previous recommendations as well as some changes to the strength of evidence supporting recommendations that have not changed. This guideline has been endorsed by the European Society for Paediatric Research (ESPR) and the Union of European Neonatal and Perinatal Societies (UENPS).

Abstract
IMPORTANCE Active postnatal care has been associated with center differences in survival among periviable infants. Regional differences in outcomes among periviable infants in the US may be associated with differences in active postnatal care. OBJECTIVE To determine if regions with higher rates of active postnatal care will have higher gestational age-specific survival rates among periviable infants. DESIGN, SETTING, AND PARTICIPANTS This cohort study included live births from 22 to 25 weeks' gestation weighing 400 to 999 g in the US Centers for Disease Control and Prevention (CDC) WONDER 2017 to 2020 (expanded) database. Infants with congenital anomalies were excluded. Active postnatal care was defined using the CDC definition of abnormal conditions of newborn as presence of any of the following: neonatal intensive care unit (NICU) admission, surfactant, assisted ventilation, antibiotics, and seizures. Data were analyzed from August to November 2022. MAIN OUTCOMES AND MEASURES Regional gestational age-specific survival rates were compared with rates of active postnatal care in the 10 US Health and Human Services regions using Kendall τ test. RESULTS We included 41 707 periviable infants, of whom 32 674 (78%) were singletons and 19 467 (46.7%) were female. Among those studied 34 983 (83.9%) had evidence of active care, and 26 009 (62.6%) survived. Regional rates of active postnatal care were positively correlated with regional survival rates at 22 weeks' gestation (rτ[8] = 0.56; r2 = 0.31; P = .03) but the correlation was not significant at 23 weeks' gestation (rτ[8] = 0.47; r2 = 0.22; P = .07). There was no correlation between active care and survival at 24 or 25 weeks' gestation. Regional rates of both NICU admission and assisted ventilation following delivery were positively correlated with regional rates of survival at 22 weeks' gestation (both P < .05). Regional rates of antenatal corticosteroids exposure were also positively correlated with regional rates of survival at 22 weeks' gestation (rτ[8] = 0.60; r2 = 0.36; P = .02). CONCLUSIONS AND RELEVANCE In this cohort study of 41 707 periviable infants, regional differences in rates of active postnatal care, neonatal intensive care unit admission, provision of assisted ventilation and antenatal corticosteroid exposure were moderately correlated with survival at 22 weeks' gestation. Further studies focused on individual-level factors associated with active periviable care are warranted.

Abstract
BACKGROUND There, we review the pathogenesis of gestational diabetes mellitus (GDM), its influence on fetal physiology, and neonatal outcomes, as well as the usage of antenatal corticosteroid therapy (ACST) in pregnancies complicated by GDM. METHODS MEDLINE and PubMed search was performed for the years 1990-2022, using a combination of keywords on such topics. According to the aim of the investigation, appropriate articles were identified and included in this narrative review. RESULTS GDM is a multifactorial disease related to unwanted pregnancy course and outcomes. Although GDM has an influence on the fetal cardiovascular and nervous system, especially in preterm neonates, the usage of ACST in pregnancy must be considered taking into account maternal and fetal characteristics. CONCLUSIONS GDM has no influence on neonatal outcomes after ACST introduction. The ACST usage must be personalized and considered according to its gestational age-specific effects on the developing fetus.

Abstract
Background Shenzhen has the largest and youngest foreign population among all cities in China. The reproductive health of pregnant women from different backgrounds is a social issue that deserves attention. In the past decade, China has liberalized its population policies to stimulate population growth, and the proportion of multiple births has continued to increase. Method This retrospective cohort included 526,654 newborns born in Baoan, Shenzhen, from January 1, 2009, to December 31, 2019, including 515,016 singletons and 11,638 twins or triplets. Univariate regression models were used to analyze the effects of maternal sociodemographic characteristics, physiological characteristics, medical history, antenatal care and other factors associated with single vs. multiple births and to elucidate the changing trends of different factors affecting multiple births in the past 11 years. Additionally, fetal development in multiple births was analyzed by generalized linear mixed models. Results The rates of pregnancy complications, preterm birth, and advanced-age pregnancy were significantly higher in the multiple birth mothers than in single birth mothers, and more multiple pregnancies were achieved through assisted reproductive technologies. The rates of adverse outcomes such as stillbirth, malformation, hypoxia, and ultralow body weight in multiple fetuses were significantly higher than that in singleton fetuses. The trend analysis from 2009 to 2019 showed that the socioeconomic status and health level of mothers with multiple births improved over time, and the risk during pregnancy generally decreased. Simultaneously, the development indicators of multiple fetuses have improved year by year, and the proportion of adverse outcomes has also decreased significantly. A low pre-natal care utilization rate was shown to be detrimental to the development of multiple fetuses. Independent risk factors for hypoxia and very low birth weight were also identified. The differences in secular trends between two birth groups were further revealed by time series models. Conclusion This study presented a comprehensive survey of multiple pregnancies in the area with the largest population inflow in China. This study identified the factors that affect the health of multiple birth mothers and their fetuses, particularly suggesting that preterm birth rates and the use of assisted reproduction remain high. The findings provide a basis for the formulation of individualized pre-natal care, assisted reproductive guidance and healthcare policies for multiple births.

Abstract
OBJECTIVE To identify regional differences in tracheostomy rates and mortality in extremely premature neonates. METHODS The 1997-2019 Kids' Inpatient Databases (KID) were queried to identify children who completed 27 weeks gestation (27-wk) or less and 23 weeks gestation (23-wk) or less. Multivariable logistic regressions compared odds of tracheostomy and mortality by region (Midwest (MW), Northeast (NE), South (S), and West (W)) while controlling for demographic variables and comorbidities. Trend analyses were performed using Poisson Regressions. RESULTS There were 2433 27-wk or less infants and 259 23-wk or less who received a tracheostomy. The MW was the only region where higher odds of tracheostomy were seen for 27-wk or less (aOR 1.25 [95%CI 1.12-1.39]) and 23-wk or less (aOR 1.68 [95%CI 1.24-2.27]) neonates when compared to all other regions combined. The S and MW had the highest increase in tracheostomy rates of 27-wk or less (β = 5.1, r = 0.77, p = 0.025; β = 3.8, r = 0.93, p = 0.001), and the MW had the highest increased rate of tracheostomy for 23-wk or less (β = 1.9, r = 0.97, p = 0.008). There were no higher mortality odds by region in 27-wk or less. Mortality was the highest in the S for 23-wk or less (20.8%, p = 0.015). CONCLUSIONS This study identified regional differences in tracheostomy rates in extremely premature infants. Extremely premature neonates in the MW had higher odds of receiving a tracheostomy with comparable mortality rates to other regions. Further research is needed to analyze regional practice differences that may impact the decision to perform a tracheostomy.

Abstract
RATIONALE An increasing number of periviable birth newborns (PVBs) have emerged with concurrent growing high-risk pregnancy. To date, postnatal management of PVBs remains one of the most challenging issues and limited studies have been reported. PATIENT CONCERNS A female baby born at 230/7 weeks of gestation with birth weight of 450g. DIAGNOSIS PVB baby, respiratory distress syndrome (RDS), ventilator associated pneumonia (VAP), intraventricular hemorrhage (IVH), metabolic bone disease of prematurity (MBDP), transient hypothyroxinemia of prematurity (THOP), bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP). INTERVENTIONS Individualized treatment and intensive care, including neonatal resuscitation, effective respiratory and circulatory support, venous access and nutrition, prevention and treatment of infection, management of endocrine and metabolic problems, individualized nursing such as developmental supportive care, integrated oral motor interventions, skin care, family-integrated-care, etc were performed according to existing literature. OUTCOMES The baby was discharged home after 138 days of hospitalization with body weight of 2700 g, a full oral feed achieved, and without any requirement of respiratory support or oxygen supply. Now she is 38-month-old, with no significant long-term adverse sequelae. LESSONS Our case expands the experience and knowledges of individualized and intensive management of PVB babies in their early life days, which increase PVBs' survival and improves their prognosis.

Abstract
OBJECTIVE To determine the rate and trend of active treatment in a population-based cohort of infants born at 22-25 weeks of gestation and to examine factors associated with active treatment. STUDY DESIGN This observational study evaluated 8247 infants born at 22-25 weeks of gestation at hospitals in the California Perinatal Quality Care Collaborative between 2011 and 2018. Multivariable logistic regression was used to relate maternal demographic and prenatal factors, fetal characteristics, and hospital level of care to the primary outcome of active treatment. RESULTS Active treatment was provided to 6657 infants. The rate at 22 weeks was 19.4% and increased with each advancing week, and was significantly higher for infants born between days 4 and 6 at 22 or 23 weeks of gestation compared with those born between days 0 and 3 (26.2% and 78.3%, respectively, vs 14.1% and 65.9%, respectively; P < .001). The rate of active treatment at 23 weeks increased from 2011 to 2018 (from 64.9% to 83.4%; P < .0001) but did not change significantly at 22 weeks. Factors associated with increased odds of active treatment included maternal Hispanic ethnicity and Black race, preterm premature rupture of membranes, obstetrical bleeding, antenatal steroids, and cesarean delivery. Factors associated with decreased odds included lower gestational age and small for gestational age birth weight. CONCLUSIONS In California, active treatment rates at 23 weeks of gestation increased between 2011 and 2018, but rates at 22 weeks did not. At 22 and 23 weeks, rates increased during the latter part of the week. Several maternal and infant factors were associated with the likelihood of active treatment.

Abstract
Advances in ventilation strategies for infants in the NICU have led to increased survival of extremely preterm infants. More than 75% of infants born at less than or equal to 27 weeks' gestation require initial mechanical ventilation for survival due to developmental immaturity of their lungs and respiratory drive. Various ventilators using different technologies and involving multiple management strategies are available for use in this population. Centers across the world have successfully used conventional, high-frequency oscillatory and high-frequency jet ventilation to manage respiratory failure in extremely preterm infants. This review explores the existing evidence for each mode of ventilation and the importance of individualizing ventilator management strategies when caring for extremely preterm infants.

Association of Antenatal Steroid Exposure at 21 to 22 Weeks of Gestation With Neonatal Survival and Survival Without Morbidities. JAMA Netw Open 2022; 5:e2233331. [PMID: 36156145 PMCID: PMC9513645 DOI: 10.1001/jamanetworkopen.2022.33331] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 08/04/2022] [Indexed: 11/14/2022] Open
Abstract
Importance The provision of antenatal corticosteroids to pregnant patients at gestational age (GA) 22 6/7 weeks or less remains controversial and lacks support from randomized clinical trials. Objective To compare rates of survival and survival without major morbidities among infants born at GA 22 0/7 to 23 6/7 weeks after exposure to antenatal steroids at 22 6/7 weeks' gestation or less vs no exposure to antenatal steroids. Design, Setting, and Participants This cohort study enrolled infants born at GA 22 0/7 to 23 6/7 weeks between January 1, 2016, and December 31, 2019, at centers in the National Institute of Child Health and Human Development Neonatal Research Network. Infants who did not receive intensive care and infants with antenatal steroid exposure after GA 22 6/7 weeks were excluded. Exposure Infants were classified as having no, partial, or complete exposure to antenatal steroids. Main Outcomes and Measures The primary outcome was survival to discharge. The main secondary outcome was survival without major neonatal morbidity. The associations of differential exposures to antenatal steroids with outcomes were evaluated using logistic regression, adjusting for GA, sex, race, maternal education, small for GA status, mode of delivery, multiple birth, prolonged rupture of membranes, year of birth, and Neonatal Research Network center. Results A total of 431 infants (mean [SD] GA, 22.6 [0.5] weeks; 232 [53.8%] boys) were included, with 110 infants (25.5%) receiving no antenatal steroids, 80 infants (18.6%) receiving partial antenatal steroids, and 241 infants (55.9%) receiving complete antenatal steroids. Seventeen infants were exposed to antenatal steroids at GA 21 weeks. Among infants exposed to complete antenatal steroids, 130 (53.9%) survived to discharge, compared with 30 infants (37.5%) with partial antenatal steroid exposure and 239 infants (35.5%) with no antenatal steroids. Infants born after complete antenatal steroid exposure, compared with those without antenatal steroid exposure, were more likely to survive to discharge (adjusted odds ratio [aOR], 1.95 [95% CI, 1.07-3.56]) and to survive without major morbidity (aOR, 2.74 [95% CI, 1.19-6.30]). Conclusions and Relevance In this retrospective cohort study, among infants born between GA 22 0/7 and 23 6/7 weeks who received intensive care, exposure to a complete course of antenatal steroids at GA 22 6/7 weeks or less was independently associated with greater odds of survival and survival without major morbidity. These data suggest that the use of antenatal steroids in patients at GA 22 6/7 weeks or less could be beneficial when active treatment is considered.

Clinical burden associated with therapies for cardio-pulmonary critical decompensation in preterm neonates across Canadian neonatal intensive care units. Eur J Pediatr 2022; 181:3319-3330. [PMID: 35779092 DOI: 10.1007/s00431-022-04508-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 05/07/2022] [Accepted: 05/14/2022] [Indexed: 12/01/2022]
Abstract
UNLABELLED The aim of this retrospective cohort study was to study the clinical burden associated with cardio-pulmonary critical decompensations (CPCDs) in preterm neonates and factors associated with mortality. Through the Canadian Neonatal Network (30 tertiary NICUs, 2010-2017), we identified infants < 32-week gestational age with CPCDs, defined by "significant exposure" to cardiotropes and/or inhaled nitric oxide (iNO): (1) either therapy for ≥ 3 consecutive days, (2) both for ≥ 2 consecutive days, or (3) any exposure within 2 days of death. Early CPCDs (≤ 3 days of age) and late CPCDs (> 3 days) were examined separately. Outcomes included CPCD-incidence, mortality, and inter-site variability using standardized ratios (observed/adjusted expected rate) and network funnel plots. Mixed-effects analysis was used to quantify unit-level variability in mortality. Overall, 10% of admissions experienced CPCDs (n = 2915). Late CPCDs decreased by ~ 5%/year, while early CPCDs were unchanged during the study period. Incidence and CPCD-associated mortality varied between sites, for both early (0.6-7.5% and 0-100%, respectively) and late CPCDs (2.5-15% and 14-83%, respectively), all p < 0.01. Units' late-CPCD incidence and mortality demonstrated an inverse relationship (slope = -2.5, p < 0.01). Mixed-effects analysis demonstrated clustering effect, with 6.4% and 8.6% of variability in mortality after early and late CPCDs respectively being site-related, unexplained by available patient-level characteristics or unit volume. Mortality was higher with combined exposure than with only-cardiotropes or only-iNO (41.3%, 24.8%, 21.5%, respectively; p < 0.01). CONCLUSIONS Clustering effects exist in CPCD-associated mortality among Canadian NICUs, with higher incidence units showing lower mortality. These data may aid network-level benchmarking, patient-level risk stratification, parental counseling, and further research and quality improvement work. WHAT IS KNOWN • Preterm neonates remain at high risk of acute and chronic complications; the most critically unwell require therapies such as cardiotropic drugs and inhaled nitric oxide. • Infants requiring these therapies are known to be at high risk for adverse neonatal outcomes and for mortality. WHAT IS NEW • This study helps illuminate the national burden of acute cardio-pulmonary critical decompensation (CPCD), defined as the need for cardiotropic drugs or inhaled nitric oxide, and highlights the high risk of morbidity and mortality associated with this disease state. • Significant nationwide variability exists in both CPCD incidence and associated mortality; a clustering effect was observed with higher incidence sites showing lower CPCD-associated mortality.

Abstract
IMPORTANCE Birth in the periviable period between 22 weeks 0 days and 25 weeks 6 days' gestation is a major source of neonatal morbidity and mortality, and the decision to initiate active life-saving treatment is challenging. OBJECTIVE To assess whether the frequency of active treatment among live-born neonates in the periviable period has changed over time and whether active treatment differed by gestational age at birth and race and ethnicity. DESIGN, SETTING, AND PARTICIPANTS Serial cross-sectional descriptive study using National Center for Health Statistics natality data from 2014 to 2020 for 61 908 singleton live births without clinical anomalies between 22 weeks 0 days and 25 weeks 6 days in the US. EXPOSURES Year of delivery, gestational age at birth, and race and ethnicity of the pregnant individual, stratified as non-Hispanic Asian/Pacific Islander, non-Hispanic Black, Hispanic/Latina, and non-Hispanic White. MAIN OUTCOMES AND MEASURES Active treatment, determined by whether there was an attempt to treat the neonate and defined as a composite of surfactant therapy, immediate assisted ventilation at birth, assisted ventilation more than 6 hours in duration, and/or antibiotic therapy. Frequencies, mean annual percent change (APC), and adjusted risk ratios (aRRs) were estimated. RESULTS Of 26 986 716 live births, 61 908 (0.2%) were periviable live births included in this study: 5% were Asian/Pacific Islander, 37% Black, 24% Hispanic, and 34% White; and 14% were born at 22 weeks, 21% at 23 weeks, 30% at 24 weeks, and 34% at 25 weeks. Fifty-two percent of neonates received active treatment. From 2014 to 2020, the overall frequency (mean APC per year) of active treatment increased significantly (3.9% [95% CI, 3.0% to 4.9%]), as well as among all racial and ethnic subgroups (Asian/Pacific Islander: 3.4% [95% CI, 0.8% to 6.0%]); Black: 4.7% [95% CI, 3.4% to 5.9%]; Hispanic: 4.7% [95% CI, 3.4% to 5.9%]; and White: 3.1% [95% CI, 1.1% to 4.4%]) and among each gestational age range (22 weeks: 14.4% [95% CI, 11.1% to 17.7%] and 25 weeks: 2.9% [95% CI, 1.5% to 4.2%]). Compared with neonates born to White individuals (57.0%), neonates born to Asian/Pacific Islander (46.2%; risk difference [RD], -10.81 [95% CI, -12.75 to -8.88]; aRR, 0.82 [95% CI, [0.79-0.86]), Black (51.6%; RD, -5.42 [95% CI, -6.36 to -4.50]; aRR, 0.90 [95% CI, 0.89 to 0.92]), and Hispanic (48.0%; RD, -9.03 [95% CI, -10.07 to -7.99]; aRR, 0.83 [95% CI, 0.81 to 0.85]) individuals were significantly less likely to receive active treatment. CONCLUSIONS AND RELEVANCE From 2014 to 2020 in the US, the frequency of active treatment among neonates born alive between 22 weeks 0 days and 25 weeks 6 days significantly increased, and there were differences in rates of active treatment by race and ethnicity.

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
AIM To describe survival and neonatal morbidities in infants born before 24 weeks of gestation during a 12-year period. METHODS Data were retrieved from national registries and validated in medical files of infants born before 24 weeks of gestation 2007-2018 in Sweden. Temporal changes were evaluated. RESULTS In 2007-2018, 282 live births were recorded at 22 weeks and 460 at 23 weeks of gestation. Survival to discharge from hospital of infants born alive at 22 and 23 weeks increased from 20% to 38% (p = 0.006) and from 45% to 67% (p < 0.001) respectively. Caesarean section increased from 12% to 22% (p = 0.038) for infants born at 22 weeks. Neonatal morbidity rates in infants alive at 40 weeks of postmenstrual age (n = 399) were unchanged except for an increase in necrotising enterocolitis from 0 to 33% (p = 0.017) in infants born at 22 weeks of gestation. Bronchopulmonary dysplasia was more common in boys than girls, 90% versus 82% (p = 0.044). The number of infants surviving to 40 weeks doubled over time. CONCLUSION Increased survival of infants born before 24 weeks of gestation resulted in increasing numbers of very immature infants with severe neonatal morbidities likely to have a negative impact on long-term outcome.

Abstract
OBJECTIVE Diagnosis-related groups (DRGs) are used to summarize hospital morbidity and mortality. Each DRG has a weight which is important in calculating the case mix index (CMI), a numeric summary of disease complexity in a population of patients. We utilized DRG weight and resultant CMI to compare postnatal outcomes among singletons versus monochorionic and monoamniotic, monochorionic diamniotic, and dichorionic diamniotic twins. STUDY DESIGN This single-center and retrospective cohort study evaluated DRGs assigned by the investigators, birth weight, gestational age, length of stay (LOS), NICU admission rate, and mortality in twin births between 2014 and 2016. Twins were analyzed depending on chorionicity and amnionicity. Overall, 3 months of singleton births served as the control. The CMI derived from DRG weights were compared across groups. RESULTS Twins (n = 288) had lower gestational ages and birth weights and higher mortality, LOS, NICU admission rates and DRG weights/CMI compared with singletons (n = 327; p < 0.001 for each). The LOS was no different between twin subtypes; monochorionic monoamniotic twins had the highest mortality and DRG weight (p < 0.001). CONCLUSION DRG weight and CMI values summarize in-hospital complexity and can be a useful tool to evaluate differences in care complexity among groups of patients. KEY POINTS · Using diagnosis-related group and case mix index to assess morbidities.. · Morbidities of twins are monochorionic-monoamniotic versus monochorionic-diamniotic versus dichorionic-diamniotic twins.. · Only seven diagnosis-related group in neonatology make it a valuable tool for clinicians..

Abstract
Background and Objectives: Extremely preterm infants were at increased risk of mortality and morbidity. The purpose of this study was to: (1) examine changes over time in perinatal management, mortality, and major neonatal morbidities among infants born at 250–286 weeks’ gestational age and cared for at one Romanian tertiary care unit and (2) compare the differences with available international data. Material and Methods: This study consisted of infants born at 250–286 weeks in one tertiary neonatal academic center in Romania during two 4-year periods (2007–2010 and 2015–2018). Major morbidities were defined as any of the following: severe intraventricular hemorrhage (IVH), severe retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), and bronchopulmonary dysplasia (BPD). Adjusted logistic regression models examined the association between the mortality and morbidity outcome and the study period. Results: The two cohorts differed with respect to antenatal antibiotics and rates of cesarean birth but had similar exposure to antenatal steroids and newborn referral to the tertiary care center. In logistic regression analyses, infants in the newer compared to the older cohort had a lower incidence of death (OR: 0.19; 95% CI: 0.11–0.35), a lower incidence of IVH (OR: 0.26; 95% CI: 0.15–0.46), and increased incidence of NEC (OR: 19.37; 95% CI: 2.41–155.11). Conclusions: Changes over time included higher use of antenatal antibiotics and cesarean delivery and no change in antenatal steroids administration. Overall mortality was lower in the newer cohort, especially for infants 250–266 weeks’ gestation, NEC was higher while BPD and ROP were not different.

Abstract
With the increase in extremely low birth weight (ELBW) infants, their outcome attracted worldwide attention. However, in China, the related studies are rare. The hospitalized records of ELBW infants discharged from twenty-six neonatal intensive care units in Guangdong Province of China during 2008-2017 were analyzed. A total of 2575 ELBW infants were enrolled and the overall survival rate was 55.11%. From 2008 to 2017, the number of ELBW infants increased rapidly from 91 to 466, and the survival rate improved steadily from 41.76% to 62.02%. Increased survival is closely related to birth weight (BW), regional economic development, and specialized hospital. The incidence of complications was neonatal respiratory distress syndrome (85.2%), oxygen dependency at 28 days (63.7%), retinopathy of prematurity (39.3%), intraventricular hemorrhage (29.4%), necrotizing enterocolitis (12.0%), and periventricular leukomalacia (8.0%). Among the 1156 nonsurvivors, 90.0% of infants died during the neonatal period (≤ 28 days). A total of 768 ELBW infants died after treatment withdrawal, for reasons of economic and/or poor outcome. The number of ELBW infants is increasing in Guangdong Province of China, and the overall survival rate is improving steadily.

Abstract
Preterm birth is a leading cause of perinatal morbidity and mortality. Antenatal corticosteroid administration before preterm birth reduces the risks of perinatal death, respiratory morbidity, necrotizing enterocolitis, and intraventricular hemorrhage and reduces the costs of perinatal care. Antenatal corticosteroids are optimally effective when administered within 7 days before preterm birth. However, only 20% to 40% of early preterm infants receive antenatal corticosteroids within 7 days before birth, in part because it is difficult to predict the precise timing of preterm birth. Until 2020, The Joint Commission had a Perinatal Care quality metric measuring the rate of antenatal corticosteroid administration at any time before early preterm birth. This metric incentivized providers to use antenatal corticosteroids liberally. The Joint Commission retired the metric in 2020 after the rate reached more than 97% in The Joint Commission-accredited hospitals. However, the metric did not evaluate whether the timing of antenatal corticosteroid administration was optimal, that is, within 7 days of birth. A 2016 multistakeholder Cooperative Workshop recommended the development of a new quality metric to assess the rate of optimally timed antenatal corticosteroids among early preterm births. In this statement, we outline proposed specifications for such a metric and discuss potential uses, advantages, limitations, and barriers. Furthermore, we propose a balancing metric that tracks the percentage of patients treated with antenatal corticosteroids who ultimately give birth at term. We suggest that the use of these new metrics may incentivize more conservative antenatal corticosteroid timing, which could, in turn, lead to meaningfully improved outcomes for preterm neonates.

Abstract
This practice guideline follows the mission of the World Association of Perinatal Medicine in collaboration with the Perinatal Medicine Foundation, bringing together groups and individuals throughout the world, with the goal of improving the use of antenatal corticosteroids (ACS) for fetal maturation. In fact, this document provides further guidance for healthcare practitioners on the appropriate use of ACS with the aim to increase the timely administration and avoid unnecessary or excessive use. Therefore, it is not intended to establish a legal standard of care. This document is based on consensus among perinatal experts throughout the world and serves as a guideline for use in clinical practice.

Abstract
OBJECTIVE Test the hypothesis potential missed opportunities for antenatal corticosteroids increase as gestational age decreases and are associated with adverse outcomes. DESIGN Observational cohort study. SETTING 24 US centers in the Neonatal Research Network. POPULATION Actively treated infants 22-25 weeks' gestation and birth weight 401-1000 grams, without major birth defects, born 2006-2018. METHODS Potential missed opportunity was defined as no antenatal corticosteroids but did have prenatal antibiotics, and/or magnesium sulfate, and/or prolonged rupture of membranes. Poisson regression models adjusted for baseline characteristics. MAIN OUTCOME MEASURES Antenatal corticosteroid exposure, mortality, and severe intracranial hemorrhage or periventricular leukomalacia. RESULTS 6966 (87.5%) were exposed to antenatal corticosteroids, 454 (5.7%) had no exposure but potential missed opportunities for antenatal corticosteroid exposure, and 537 (6.7%) had no exposure and no evidence of potential missed opportunities. Compared with infants born at 25 weeks, potential missed opportunities for antenatal corticosteroid exposure were more likely at 22 weeks (adjusted relative risk (aRR) [95% CI] 11.06 [7.52-16.27]) and 23 weeks (3.24 [2.44-4.29]) but did not differ at 24 weeks (1.08 [0.82-1.42]). Potential missed opportunities for antenatal corticosteroids decreased over time at 22-23 weeks' gestation. Antenatal corticosteroid exposed infants had lower risk of death (31.0% vs 54.8%; 0.77 [0.70-0.84]) and survivors had lower risk of severe brain injury (25.0% v 44.5%; 0.64 [0.55-0.73]) compared with infants with potential missed opportunities. CONCLUSION Potential missed opportunities for antenatal corticosteroid exposure increased with decreasing gestational age and were associated with higher rates of death and severe brain injury among actively treated periviable births.

Abstract
Aim To assess the strength of associations between interrelated perinatal risk factors and mortality in very preterm infants. Methods Information on all live‐born infants delivered in Sweden at 22–31 weeks of gestational age (GA) from 2011 to 2019 was gathered from the Swedish Neonatal Quality Register, excluding infants with major malformations or not resuscitated because of anticipated poor prognosis. Twenty‐seven perinatal risk factors available at birth were exposures and in‐hospital mortality outcome. Orthogonal partial least squares discriminant analysis was applied to assess proximity between individual risk factors and mortality, and receiver operating characteristic (ROC) curves were used to estimate discriminant ability. Results In total, 638 of 8,396 (7.6%) infants died. Thirteen risk factors discriminated reduced mortality; the most important were higher Apgar scores at 5 and 10 min, GA and birthweight. Restricting the analysis to preterm infants <28 weeks’ GA (n = 2939, 16.9% mortality) added antenatal corticosteroid therapy as significantly associated with lower mortality. The area under the ROC curve (the C‐statistic) using all risk factors was 0.86, as determined after both internal and external validation. Conclusion Apgar scores, gestational age and birthweight show stronger associations with mortality in very preterm infants than several other perinatal risk factors available at birth.

Abstract
PURPOSE OF REVIEW Ventilation of periviable infants born at 22-23 weeks gestation remains a challenge in neonatology. This review highlights the evidence surrounding the use of first intention high-frequency jet ventilation (HFJV) in infants born near the limits of viability with a review of pulmonary fetal development and a focused overview of HFJV strategies including an in-depth analysis of the management strategies used in the initial randomized trials. RECENT FINDINGS A paucity of recent trials exists, with no randomized control trials assessing the use of first intention HFJV performed in the last 25 years. A retrospective observational cohort trial of the use of HFJV for infants born at less than 750 g has been recently published demonstrating the efficacy of HFJV for this population even with 2.0-mm endotracheal tubes. SUMMARY The lack of recent randomized trials contributes to the controversy surrounding the use of first intention HFJV. Although new research is needed in the area, this review includes the ventilation strategy of an experienced center with a focus on the use of first intention HFJV for the care of premature infants born less than 24 weeks gestation.

Abstract
Lung immaturity and acute respiratory failure are the major problems in the care of extremely preterm infants. Most infants with gestational age (GA) 22-24 weeks will need mechanical ventilation and many will depend on some type of respiratory support, invasive and non-invasive for extended periods. There is ongoing gap in knowledge regarding optimal respiratory support and applying strategies that are effective in more mature populations is not easy or even suitable because lung maturation differs in smaller infants. Better strategies on how to avoid lung damage and to promote growth and development of the immature lung are warranted since increased survival is accompanied by increasing rates of bronchopulmonary dysplasia and concerns over long-standing reductions in lung function. This review focuses on some aspects of respiratory care of infants born at 22-24 weeks of GA.

Abstract
Decision-making at the border of viability remains challenging for the expectant parents and the medical team. The preterm infant is dependent on others making the decision that will impact them for a lifetime in hopefully their best interest. Besides survival and survival without neurodevelopmental impairment, other relevant outcome measures, such as the quality of life of former preterm infants and the impact on family life, need to be integrated into prenatal counselling. Recommendations and national guidelines continue to rely on arbitrarily set gestational age limits at which treatment is not recommended, can be considered and it is recommended. These guidelines neglect other individual prognostic outcome factors like antenatal steroids, birth weight and gender. Besides individual factors, centre-specific factors like perinatal treatment intensity and the attitude of healthcare professionals significantly determine the futures of these infants at the border of viability. A more comprehensive approach regarding treatment recommendations and relevant outcome measures is necessary.

Abstract
IMPORTANCE Understanding why and how extremely preterm infants die is important for practitioners caring for these infants. OBJECTIVE To examine risk factors, causes, timing, and circumstances of death in a modern cohort of extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort review of infants enrolled in the Preterm Erythropoietin Neuroprotection Trial between December 13, 2013, and September 26, 2016, was conducted. A total of 941 infants born between 24 0/7 and 27 6/7 weeks of gestation enrolled at 19 US sites comprising 30 neonatal intensive care units were included. Data analysis was performed from October 16, 2020, to December 1, 2021. MAIN OUTCOMES AND MEASURES Risk factors, proximal causes, timing, and circumstances of in-hospital death. RESULTS Of the 941 enrolled infants, 108 died (11%) before hospital discharge: 38% (n = 41) at 24 weeks' gestation, 30% (n = 32) at 25 weeks' gestation, 19% (n = 20) at 26 weeks' gestation, and 14% (n = 15) at 27 weeks' gestation. An additional 9 infants (1%) died following hospital discharge. In descending order, the primary causes of death included respiratory distress or failure, pulmonary hemorrhage, necrotizing enterocolitis, catastrophic intracranial hemorrhage, sepsis, and sudden unexplained death. Fifty percent of deaths occurred within the first 10 days after birth. The risk of death decreased with day of life and postmenstrual age such that an infant born at 24 weeks' gestation who survived 14 days had the same risk of death as an infant born at 27 weeks' gestation: conditional proportional risk of death, 0.08 (95% CI, 0.03-0.13) vs 0.06 (95% CI, 0.01-0.11). Preterm labor was associated with a decreased hazard of death (hazard ratio [HR], 0.45; 95% CI, 0.31-0.66). Infant clinical factors associated with death included birth weight below the tenth percentile for gestational age (HR, 2.11; 95% CI, 1.38-3.22), Apgar score less than 5 at 5 minutes (HR, 2.19; 95% CI, 1.48-3.24), sick appearance at birth (HR, 2.49; 95% CI, 1.69-3.67), grade 2b-3 necrotizing enterocolitis (HR, 7.41; 95% CI, 5.14-10.7), pulmonary hemorrhage (HR, 10.0; 95% CI, 6.76-18.8), severe intracranial hemorrhage (HR, 4.60; 95% CI, 3.24-5.63), and severe sepsis (HR, 4.93; 95% CI, 3.67-7.21). Fifty-one percent of the infants received comfort care before death. CONCLUSIONS AND RELEVANCE In this cohort study, an association between mortality and gestational age at birth was noted; however, for each week that an infant survived, their risk of subsequent death approximated the risk observed in infants born 1 to 2 weeks later, suggesting the importance of an infant's postmenstrual age. This information may be useful to include in counseling of families regarding prognosis of survival.

Abstract
OBJECTIVES Our objective with this quality improvement initiative was to reduce rates of severe intracranial hemorrhage (ICH) or death in the first week after birth among extremely preterm infants. METHODS The quality improvement initiative was conducted from April 2014 to September 2020 at the University of Alabama at Birmingham's NICU. All actively treated inborn extremely preterm infants without congenital anomalies from 22 + 0/7 to 27 + 6/7 weeks' gestation with a birth weight ≥400 g were included. The primary outcome was severe ICH or death in the first 7 days after birth. Balancing measures included rates of acute kidney injury and spontaneous intestinal perforation. Outcome and process measure data were analyzed by using p-charts. RESULTS We studied 820 infants with a mean gestational age of 25 + 3/7 weeks and median birth weight of 744 g. The rate of severe ICH or death in the first week after birth decreased from the baseline rate of 27.4% to 15.0%. The rate of severe ICH decreased from a baseline rate of 16.4% to 10.0%. Special cause variation in the rate of severe ICH or death in the first week after birth was observed corresponding with improvement in carbon dioxide and pH targeting, compliance with delayed cord clamping, and expanded use of indomethacin prophylaxis. CONCLUSIONS Implementation of a bundle of evidence-based potentially better practices by using specific electronic order sets was associated with a lower rate of severe ICH or death in the first week among extremely preterm infants.

Abstract
The care of infants born at the lowest extreme of gestation requires dedication, skill, and experience. Most centers apply a selective approach where intensive care at these gestational ages is being offered to a varying proportion of infants depending on the views and experiences of the medical community, the individual physician, and the parents. Consequently, the outcomes differ dramatically with survival rates at 22-23 weeks ranging from 0 to greater than 50%. This paper presents the approach in a center with a long tradition of providing a comprehensive and uniformly active care to all mother-infant dyads from 22+0 weeks of gestation. Important features outlined include prenatal maternal referral and transfer, delivery room management, and initial intensive care.

Abstract
Survival of preterm newborn infants have increased steadily since the introduction of surfactant treatment and antenatal steroids. In the absence of randomized controlled trials on ventilatory strategies in extremely preterm infants, we present ventilatory strategies applied during the initial phase and the continued ventilatory care as applied in three centers with proactive prenatal and postnatal management and well documented good outcomes in terms of mortality and morbidity in this cohort of infants.

Abstract
Marked variation exists in the care of infants born at <25 weeks' gestation. The center or location where a fetus or infant is cared for influences outcomes at very early gestational ages. Understanding this "center-effect," including characteristics associated with centers that have high survival of births at <25 weeks' gestation, may inform future studies and guide care practices to improve outcomes. This review focuses on the impact that the location or center of birth has on survival and other important outcomes for infants born at <25 weeks' gestation. We review potential sources of variation in care practices and other factors that might explain the "center-effect."

Abstract
IMPORTANCE Despite improvement during recent decades, extremely preterm infants continue to contribute disproportionately to neonatal mortality and childhood morbidity. OBJECTIVE To review survival, in-hospital morbidities, care practices, and neurodevelopmental and functional outcomes at 22-26 months' corrected age for extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS Prospective registry for extremely preterm infants born at 19 US academic centers that are part of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. The study included 10 877 infants born at 22-28 weeks' gestational age between January 1, 2013, and December 31, 2018, including 2566 infants born before 27 weeks between January 1, 2013, and December 31, 2016, who completed follow-up assessments at 22-26 months' corrected age. The last assessment was completed on August 13, 2019. Outcomes were compared with a similar cohort of infants born in 2008-2012 adjusting for gestational age. EXPOSURES Extremely preterm birth. MAIN OUTCOMES AND MEASURES Survival and 12 in-hospital morbidities were assessed, including necrotizing enterocolitis, infection, intracranial hemorrhage, retinopathy of prematurity, and bronchopulmonary dysplasia. Infants were assessed at 22-26 months' corrected age for 12 health and functional outcomes, including neurodevelopment, cerebral palsy, vision, hearing, rehospitalizations, and need for assistive devices. RESULTS The 10 877 infants were 49.0% female and 51.0% male; 78.3% (8495/10848) survived to discharge, an increase from 76.0% in 2008-2012 (adjusted difference, 2.0%; 95% CI, 1.0%-2.9%). Survival to discharge was 10.9% (60/549) for live-born infants at 22 weeks and 94.0% (2267/2412) at 28 weeks. Survival among actively treated infants was 30.0% (60/200) at 22 weeks and 55.8% (535/958) at 23 weeks. All in-hospital morbidities were more likely among infants born at earlier gestational ages. Overall, 8.9% (890/9956) of infants had necrotizing enterocolitis, 2.4% (238/9957) had early-onset infection, 19.9% (1911/9610) had late-onset infection, 14.3% (1386/9705) had severe intracranial hemorrhage, 12.8% (1099/8585) had severe retinopathy of prematurity, and 8.0% (666/8305) had severe bronchopulmonary dysplasia. Among 2930 surviving infants with gestational ages of 22-26 weeks eligible for follow-up, 2566 (87.6%) were examined. By 2-year follow-up, 8.4% (214/2555) of children had moderate to severe cerebral palsy, 1.5% (38/2555) had bilateral blindness, 2.5% (64/2527) required hearing aids or cochlear implants, 49.9% (1277/2561) had been rehospitalized, and 15.4% (393/2560) required mobility aids or other supportive devices. Among 2458 fully evaluated infants, 48.7% (1198/2458) had no or mild neurodevelopmental impairment at follow-up, 29.3% (709/2419) had moderate neurodevelopmental impairment, and 21.2% (512/2419) had severe neurodevelopmental impairment. CONCLUSIONS AND RELEVANCE Among extremely preterm infants born in 2013-2018 and treated at 19 US academic medical centers, 78.3% survived to discharge, a significantly higher rate than for infants born in 2008-2012. Among infants born at less than 27 weeks' gestational age, rehospitalization and neurodevelopmental impairment were common at 2 years of age.
