Abstract
BACKGROUND There is little information about neonatal follow-up programs (NFUPs) in China. This study aimed to conduct a survey of hospitals participating in the Chinese Neonatal Network (CHNN) to determine the status of NFUPs, including resources available, criteria for enrollment, neurodevelopmental assessments, and duration of follow-up. METHODS We conducted a descriptive study using an online survey of all 72 hospitals participating in CHNN in 2020. The survey included 15 questions that were developed based on the current literature and investigators' knowledge about follow-up practices in China. RESULTS Sixty-four (89%) of the 72 hospitals responded to the survey, with an even distribution of children's (31%), maternity (33%) and general (36%) hospitals. All but one (98%) hospital had NFUPs, with 44 (70%) being established after 2010. Eligibility criteria for follow-up were variable, but common criteria included very preterm infants < 32 weeks or < 2000 g birth weight (100%), small for gestational age (97%), hypoxic ischemic encephalopathy (98%) and postsurgery (90%). The average follow-up rate was 70% (range: 7.5%-100%). Only 12% of hospitals followed up with patients for more than 24 months. There was significant variation in neurodevelopmental assessments, follow-up schedule, composition of staff, and clinic facilities and resources. None of the staff had received formal training, and only four hospitals had sent staff to foreign hospitals as observers. CONCLUSIONS There is significant variation in eligibility criteria, duration of follow-up, types of assessments, staffing, training and facilities available. Coordination and standardization are urgently needed.

Abstract
OBJECTIVE This study was conducted to determine the prevalence and risk factors for retinopathy of prematurity (ROP) in two neonatal intensive care units (NICUs) in Addis Ababa, Ethiopia. METHODS AND ANALYSIS A prospective screening survey was conducted from June 2019 to June 2020 in two level 3 public NICUs. Infants with a birth weight (BW) of ≤1500 g or gestational age (GA) of ≤32 weeks and those with a BW of >1500 g and GA of >32 weeks with an unstable clinical course were included. Data on demographic and neonatal characteristics, neonatal and maternal comorbidities, and therapeutic interventions were collected. Logistic regression analysis was used to identify predictors of ROP. RESULTS Two hundred and two infants were included: mean BW: 1658g (range: 700-2400 g) and mean GA: 32.4 weeks (range: 26-34 weeks). 32.2% had any stage of ROP, and 6.4% had Type 1 ROP. Lower BW, smaller GA and total days on oxygen were independent risk factors for severe ROP (Type 1 or worse). All 13 neonates with severe ROP were treated. CONCLUSION ROP is emerging as a concern in Ethiopia. ROP screening should include neonates with BW of <1800 g or GAs of ≤33 weeks, but further studies are needed in level 2 and private NICUs. Screening guidelines need to be developed and implemented in all hospitals with NICUs.

Pediatr Res 2023; 93:541-550. [PMID: 35701606 DOI: 10.1038/s41390-022-02152-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 05/18/2022] [Accepted: 05/26/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND The pathogenesis of neonatal meconium aspiration syndrome (MAS) involves meconium-induced lung inflammation and surfactant inactivation. Bronchoalveolar lavage (BAL) with diluted surfactant facilitates the removal of meconium. CHF5633, one of the most promising synthetic surfactants, is effective in neonatal respiratory distress syndrome. Here we investigated its efficacy via BAL in an experimental MAS model. METHODS Experimental MAS was induced at birth in near-term newborn rabbits by intratracheal instillation of reconstituted human meconium. First, undiluted CHF5633 was compared with a porcine-derived surfactant (Poractant alfa) via intratracheal bolus (200 mg/kg). Second, the efficacy of BAL with diluted CHF5633 (5 mg/mL, 20 ml/kg) alone, or followed by undiluted boluses (100 or 300 mg/kg), was investigated. RESULTS Meconium instillation caused severe lung injury, reduced endogenous surfactant pool, and poor survival. CHF5633 had similar benefits in improving survival and alleviating lung injury as Poractant alfa. CHF5633 BAL plus higher boluses exerted better effects than BAL or bolus alone in lung injury alleviation by reversing phospholipid pools and mitigating proinflammatory cytokine mRNA expression, without fluid retention and function deterioration. CONCLUSIONS CHF5633 improved survival and alleviated meconium-induced lung injury, the same as Poractant alfa. CHF5633 BAL plus boluses was the optimal modality, which warrants further clinical investigation. IMPACT To explore the efficacy of a synthetic surfactant, CHF5633, in neonatal lung protection comparing with Poractant alfa in a near-term newborn rabbit model with meconium-induced lung injury. Similar effects on improving survival and alleviating lung injury were found between CHF5633 and Poractant alfa. Optimal therapeutic effects were identified from the diluted CHF5633 bronchoalveolar lavage followed by its undiluted bolus instillation compared to the lavage or bolus alone regimens. Animals with CHF5633 lavage plus bolus regimen exerted neither substantial lung fluid retention nor lung mechanics deterioration but a trend of higher pulmonary surfactant-associated phospholipid pools.

Peripheral perfusion index in well newborns at 6 to 72 h of life at different altitudes: a multi-center study in China. Eur J Pediatr 2023; 182:907-915. [PMID: 36525095 PMCID: PMC9899177 DOI: 10.1007/s00431-022-04725-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 11/17/2022] [Accepted: 11/18/2022] [Indexed: 12/23/2022]
Abstract
The purpose of this study is to obtain the reference range of peripheral perfusion index (PPI) of asymptomatic well newborns at 6 to 72 h of life at different altitudes. A population-based prospective cohort study was conducted in cities at different altitudes in China. Asymptomatic well newborns were enrolled consecutively from six hospitals with an altitude of 4 to 4200 m between February 1, 2020, and April 15, 2021. PPI was measured at 6, 12, 24, 48, and 72 h after birth on the right hand (pre-ductal) and either foot (post-ductal) using a Masimo SET Radical-7 oximeter. Fiftieth percentile reference curves of the pre- and post-ductal PPI values at 6-72 h after birth were generated using the Lambda Mu Sigma method. Linear mixed-effects regression was performed to determine the influence of different altitude levels on PPI values over different measurement time points. A total of 4257 asymptomatic well newborns were recruited for analysis. The median and quartile pre- and post-ductal PPI values at 6-72 h of life at different altitudes were 1.70 (1.20, 2.60) and 1.70 (1.10, 2.70) for all infants, 1.30 (1.10, 1.90) and 1.10 (0.88, 1.80) for infants at low altitude, 1.40 (1.00, 2.00) and 1.30 (0.99, 2.00) at mild altitudes, 1.90 (1.30, 2.50) and 1.80 (1.20, 2.70) at moderate altitudes, 1.80 (1.40, 3.50) and 2.20 (1.60, 4.30) for high altitudes, 3.20 (2.70, 3.70), and 3.10 (2.10, 3.30) for higher altitudes, respectively. Overall, both pre- and post-ductal PPI increased with altitude. The 50th percentile curves of pre- and post-ductal PPI values in well newborns at mild, low, moderate, and high altitudes were relatively similar, while the difference between the PPI curves of infants at higher altitudes and other altitudes was significantly different. Conclusions: With the increase of altitude, pre- and post-ductal PPI of newborns increases. Our study obtained the PPI reference values of asymptomatic well newborns at 6 to 72 h after birth at different altitudes from 4 to ≥ 4000 m. What is Known: • Monitoring hemodynamics is very important to neonates. As an accurate and reliable hemodynamic monitoring index, PPI can detect irreversible damage caused by insufficient tissue perfusion and oxygenation early, directly, noninvasively, and continuously. What is New: • Our study obtained the PPI reference values of asymptomatic well newborns at 6 to 72 h after birth at different altitudes from 4 to ≥ 4000 m. With the increase of altitude, pre- and post-ductal PPI of newborns increase with statistical significance. Therefore, the values and disease thresholds of PPI for asymptomatic neonates should be modified according to altitudes.

Abstract
BACKGROUND There is limited evidence about the influence of human milk feeding on short-term outcomes in a large preterm infant population. RESEARCH AIMS To explore the influences of human milk feeding on the primary outcome of necrotizing enterocolitis and secondarily sepsis, bronchial pulmonary dysplasia, severe retinopathy of prematurity, death, and the time to achieve full enteral feeding at discharge in very/extremely low-birth-weight infants. METHODS This study was a retrospective, longitudinal, observational two-group comparison cohort study. A total of 4470 very/extremely low-birth-weight infants from 25 neonatal intensive care units in China, between April 2015 and May 2018, were enrolled in this study. Exclusive human milk-fed and formula-fed participants were matched using propensity scores. After matching, human milk-fed participants (n = 1379) and formula-fed participants (n = 1378) were included in the analyses. The likelihood of necrotizing enterocolitis, bronchopulmonary dysplasia, sepsis, severe retinopathy of prematurity, death, and the time to achieve full enteral feeding were compared between the two groups. RESULTS Exclusive human milk feeding was associated with lower odds of necrotizing enterocolitis (2.90% vs. 8.42%, OR 0.33, 95% CI [0.22, 0.47]), bronchopulmonary dysplasia (15.74% vs. 20.26%, OR 0.69, 95% CI [0.56, 0.86]), severe retinopathy of prematurity (1.45% vs. 2.39%, OR 0.50, 95% CI [0.27, 0.93]), and death (6.02% vs. 10.38%, OR 0.44, 95% CI [0.32, 0.61]) compared with formula feeding. No significant differences in the time to achieve full enteral feeding or the odds of sepsis were found between the two groups. CONCLUSION Exclusive human milk feeding is associated with a reduction in necrotizing enterocolitis, bronchopulmonary dysplasia, severe retinopathy of prematurity, and mortality among very/extremely low-birth-weight infants.

Abstract
Neonatal retinal hemorrhage (RH) is the most common ocular fundus disease among newborns. Early detection and timely intervention are vital for reducing the risk of visual impairment caused by RH. However, little is known about the prevalence, characteristics, and risk factors of RH in southern China. Full-term infants born in Qingyuan City during the first 10 days of each month in 2021 were included in this study. All infants underwent RetCam III retinal examinations. Detailed information on retinal hemorrhage, including involved eyes, bleeding severity, and affected area (extrafoveal macula, fovea, or optic disc), and clinical information on the neonates and their mothers was collected. The results showed that among the 1072 eligible neonates, 266 (24.8%) had neonatal retinal hemorrhage. Consistent bilateral retinal hemorrhage severity was observed in 83.2% of the cases. The prevalence of optic disc involved RH, extrafoveal macular involved RH and foveal involved RH were 23.7%, 81.2% and 2.63%, respectively. Multivariate logistic regression analysis showed that lower birth weight (OR, 0.63; 95% CI, 0.40-0.99; p < 0.05) and vaginal delivery (OR, 20.6; 95% CI, 9.10-46.5; p < 0.001) were risk factors of neonatal RH. The area under the ROC curve of vaginal delivery, combined with birth weight, as predictors of neonatal RH was 0.73, with 85.3% sensitivity and 23.9% specificity. The birth weight cutoff was 3460 g. Our results suggested that neonatal RH is common in full-term neonates in southern China. It usually has the same severity in both eyes and mostly involves the extrafoveal macular region. Vaginal delivery and low birth weight are risk factors for neonatal RH.

Abstract
Abstract
Background
To explore the prevalence, outcome and perinatal risks of neonatal hypoxemic respiratory failure (NRF) in a survey of all livebirths from a regional network of perinatal-neonatal care during the transition period after 5-year universal health insurance implemented in China.
Methods
Clinical data of all neonatal respiratory morbidities in Huai’an were retrospectively collected in the regional perinatal network database of all livebirths as vital statistics in 2015. NRF was defined as hypoxemia requiring continuous positive airway pressure (CPAP) and/or mechanical ventilation (MV) for at least 24 h. Mortality risks of antenatal and perinatal morbidities, major respiratory therapies and complications were analyzed by multivariable logistic regression model.
Results
There were 788 NRF cases identified in 9.9% (7960) hospitalized, or 13.3‰ (59056) livebirths, in which 6.7% received intensive care and 93.0% critical care. The major underlying morbidities were respiratory distress syndrome (RDS, 36.4%) and pneumonia/sepsis (35.3%), treated mainly by CPAP, MV and surfactant. Significantly improved outcomes by surfactant in RDS were in patients with birthweight (BW) < 1500 g or gestational age (GA) < 32 weeks. The overall mortality rate in NRF was 18.4% whereas for those of BW < 1000 g and GA < 28 weeks, 70% and 54%, respectively. The multivariable regression analysis showed the highest odds for NRF death among meconium aspiration syndrome, congenital anomalies, BW < 1500 g and necrotizing enterocolitis, whereas born in level III hospitals, cesarean delivery, CPAP and MV were associated with markedly reduced death odds.
Conclusions
The salient findings with associated risk estimates reflected efficiency of respiratory support as critical care in a prefectural regional network infrastructure for annual livebirths in 5.6 million inhabitants. It implicated the representativeness of contemporaneous perinatal-neonatal care standard at medium to medium-high level, in one/fourth of the population of China, aiming at saving more life of very critical and preterm infants for better survival.

Abstract
Background Current vital statistics of birth population and neonatal outcome in China lacked information and definition of deaths at delivery and during hospitalization, especially for extreme preterm (EPT) birth. This study aims to delineate the prevalence of neonatal hospitalization, neonatal and infant mortality rates (NMR, IMR) and associated perinatal risks based on all livebirths in Huai’an, an evolving sub-provincial region in eastern China. Methods This retrospective cohort study established a comprehensive database linking information of whole regional livebirths and neonatal hospitalization in 2015, including deaths at delivery and EPT livebirths. The primary outcomes were NMR and IMR stratified by gestational age (GA) and birthweight (BW) with 95% confidence intervals. Causes of the neonatal and infant deaths were categorized according to the International Statistical Classification of Diseases 10th version, and population attributable fractions of GA and BW strata were analyzed. Perinatal risks of infant mortalities in continuum periods were estimated by Cox regression models. Results Among the whole livebirth population (59056), 7960 were hospitalized (prevalence 13.5%), with 168 (2.8‰) in-hospital deaths. The NMR was 3.6 (3.2, 4.1)‰ and IMR 4.9 (1.4, 4.5)‰, with additionally 35 (0.6‰) deaths at delivery. The major causes of infant deaths were perinatal conditions (2.6‰, mainly preterm-related), congenital anomalies (1.5‰), sudden unexpected death in infancy (0.6‰) and other causes (0.2‰). The deaths caused by preterm and low BW (LBW) accounted for 50% and 40% of NMR and IMR, with 20-30% contributed by EPT or extremely LBW, respectively. Multivariable Cox regression analysis revealed that peripartum factors and LBW strata had strong association with early- and late-neonatal deaths, whereas those of GA < 28 weeks were highly associated with postneonatal deaths. Congenital anomalies and neonatal hospitalization remained high death risks over the entire infancy, whereas maternal co-morbidities/complications were modestly associated with neonatal but not postneonatal infant mortality. Conclusions The NMR, IMR, major causes of deaths and associated perinatal risks in continuum periods of infancy, denote the status and quality improvement of the regional perinatal-neonatal care associated with socioeconomic development. The study concept, applicability and representativeness may be validated in other evolving regions or countries for genuine comparison and better maternal-infant healthcare.

Abstract
BACKGROUND Reliable data for causal implication of neonatal survival in China are lacking. We assumed that by analyzing surviving data of in-hospital neonatal care based on all livebirths in Huai'an, prevalence of neonatal morbidity, mortality and causal relations may be derived comprehensively. MATERIALS AND METHODS Data of all regionally hospitalized neonates were retrospectively linked with corresponding whole livebirths (59,056) in 2015 as a cohort. Diagnoses of diseases and causes of deaths were redefined and categorized. Disease patterns, prevalence of morbidities, case-fatality rate (CFR), and cause-specific mortality rate (CSMR) referring to livebirths were presented. Perinatal and disease-specific risks of death were estimated by multivariable logistic regression. RESULTS In 7,960 (134.8‰) hospitalized patients, 168 (2.1%) died in hospital (2.85‰ of livebirths). Prevalence of major morbidities were 76.8‰ hyperbilirubinemia, 57.4‰ pneumonia, 32.7‰ intraventricular hemorrhage, 20.7‰ sepsis, 20.2‰ birth asphyxia, 9.69‰ congenital anomalies (CA), and 5.30‰ respiratory distress syndrome (RDS). The CFR (CSMR) of major diseases were 30.4% (0.12‰) meconium aspiration syndrome, 17.6% (0.22‰) necrotizing enterocolitis, 14.1% (0.75‰) RDS, 9.09% (0.88‰) CA, 5.26% (0.07‰) bronchopulmonary dysplasia, 1.71% (0.36‰) sepsis and 1.51% (0.31‰) asphyxia. Overall mortality rates were 4.6% and 6.8% in the preterm and low birthweight, and >50% in those of <28 week gestation or <1000 g birthweight, respectively. Mortality risks associated with the perinatal and neonatal morbidities were markedly declined with variable magnitude by multivariable regression models. CONCLUSIONS The in-hospital neonatal survival datafile, depicted as the prevalence of major morbidities and CSMR of livebirth population in Huai'an, denoted overall and specific quality and efficiency of the perinatal-neonatal care system. Its concept and methodology should be relevant, and outcome extrapolated, to other countries or domestic regions, with similar socioeconomic development.

Abstract
PURPOSE To describe the current incidence, case-fatality rate and surgical treatment proportion of necrotizing enterocolitis (NEC) among preterm infants in China. METHODS The study included all live neonates with <34 weeks gestational age (GA) admitted to 25 tertiary hospitals within 7 days of birth from 19 provinces in China between May 2015 and April 2018. NEC was defined as ≥stage II according to Bell's criteria. RESULTS A total of 24,731 infants were included. The overall incidence of NEC was 3.3% and decreased with increasing GA and birth weight. The incidence of NEC was 4.8% in very preterm infants and 1.8% in infants born ≥32 weeks GA, respectively. The overall case-fatality rate of NEC was 9.5%, and the case-fatality rate was 7.0% among infants born ≥32 weeks GA. A total of 214 (27.9%) infants underwent surgery, and their overall case-fatality rate was 13.6%. Significant variation in the incidence of NEC existed among different centers (0.6-11.1%). CONCLUSIONS The incidence and case-fatality rate of NEC are high in China, especially among infants with GA ≥32 weeks, and varies significantly among sites. A high proportion of NEC infants required surgical management, with an even higher case-fatality rate.

Abstract
Neonatal nurses in mainland China encounter various challenges when it comes to delivering palliative care to neonates. The aim of this study was to determine the barriers and facilitators of neonatal nurses' attitudes to palliative care for neonates in mainland China. A simplified Chinese version of the Neonatal Palliative Care Attitude Scale was piloted, administered, and analyzed using survey methods. Nurses in neonatal intensive care units in mainland China regardless of experience in the field were invited to take part in. Over a five-month period in 2019, we surveyed neonatal nurses from 40 hospitals in five provinces of China. The response rate was 92.5% (N = 550). This study identified eight facilitators and four barriers to neonatal palliative care implementation. In terms of nurses' attitudes on providing palliative care, younger and older nurses were more positive, whereas middle-aged nurses were less so. Nurses' emotional wellbeing was rarely impacted by neonatal death. They considered neonatal palliative care, particularly pain management, to be just as important as curative treatment. Parents were invited to participate in decision-making by nurses. Nurses reported having access to professional counseling and talking about their concerns with other healthcare professionals. The following barriers to neonatal palliative care were identified in this study that were not observed in the original English version scale research in 2009: a lack of clinicians, time, clinical skills, systematic education, neonatal palliative care experience, and social acceptance. Future research is required to investigate each barrier in order to improve the implementation of neonatal palliative care in mainland China.

Abstract
IMPORTANCE The Chinese Neonatal Network was established in 2018 and maintains a standardized national clinical database of very preterm or very low-birth-weight infants in tertiary neonatal intensive care units (NICUs) throughout China. National-level data on outcomes and care practices of very preterm infants (VPIs) in China are lacking. OBJECTIVE To assess the care practices in NICUs and outcomes among VPIs in China. DESIGN, SETTING, AND PARTICIPANTS A cohort study was conducted comprising 57 tertiary hospitals from 25 provinces throughout China. All infants with gestational age (GA) less than 32 weeks who were admitted to the 57 NICUs between January 1 and December 31, 2019, were included. MAIN OUTCOMES AND MEASURES Care practices, morbidities, and survival were the primary outcomes of the study. Major morbidities included bronchopulmonary dysplasia, severe intraventricular hemorrhage (grade ≥3) and/or periventricular leukomalacia, necrotizing enterocolitis (stage ≥2), sepsis, and severe retinopathy of prematurity (stage ≥3). RESULTS A total of 9552 VPIs were included, with mean (SD) GA of 29.5 (1.7) weeks and mean (SD) birth weight of 1321 (321) g; 5404 infants (56.6%) were male. Antenatal corticosteroids were used in 75.6% (6505 of 8601) of VPIs, and 54.8% (5211 of 9503)were born through cesarean delivery. In the delivery room, 12.1% of VPIs received continuous positive airway pressure and 26.7% (2378 or 8923) were intubated. Surfactant was prescribed for 52.7% of the infants, and postnatal dexamethasone was prescribed to 9.5% (636 of 6675) of the infants. A total of 85.5% (8171) of the infants received complete care, and 14.5% (1381) were discharged against medical advice. The incidences of the major morbidities were bronchopulmonary dysplasia, 29.2% (2379 of 8148); severe intraventricular hemorrhage and/or periventricular leukomalacia, 10.4% (745 of 7189); necrotizing enterocolitis, 4.9% (403 of 8171 ); sepsis, 9.4% (764 of 8171); and severe retinopathy of prematurity, 4.3% (296 of 6851) among infants who received complete care. Among VPIs with complete care, 95.4% (7792 of 8171) survived: 65.6% (155 of 236) at 25 weeks' or less GA, 89.0% (880 of 988) at 26 to 27 weeks' GA, 94.9% (2635 of 2755)at 28 to 29 weeks' GA, and 98.3% (4122 of 4192) at 30 to 31 weeks' GA. Only 57.2% (4677 of 8171) of infants survived without major morbidity: 10.5% (25 of 236) at 25 weeks' or less GA, 26.8% (48 of 179) at 26 to 27 weeks' GA, 51.1% (1409 of 2755) at 28 to 29 weeks' GA, and 69.3% (2904 of 4192) at 30 to 31 weeks' GA. Among all infants admitted, the survival rate was 87.6% (8370 of 9552)and survival without major morbidities was 51.8% (4947 of 9552). CONCLUSIONS AND RELEVANCE The findings of this study suggest that survival and survival without major morbidity of VPIs in Chinese NICUs have improved but remain lower than in high-income countries. Comprehensive and targeted quality improvement efforts are needed to provide complete care for all VPIs, optimize obstetrical and neonatal care practices, and improve outcomes.

Abstract
Background Despite 15–17 millions of annual births in China, there is a paucity of information on prevalence and outcome of preterm birth. We characterized the outcome of preterm births and hospitalized preterm infants by gestational age (GA) in Huai’an in 2015, an emerging prefectural region of China. Methods Of 59,245 regional total births, clinical data on 2651 preterm births and 1941 hospitalized preterm neonates were extracted from Huai’an Women and Children’s Hospital (HWCH) and non-HWCH hospitals in 2018–2020. Preterm prevalence, morbidity and mortality rates were characterized and compared by hospital categories and GA spectra. Death risks of preterm births and hospitalized preterm infants in the whole region were analyzed with multivariable Poisson regression. Results The prevalence of extreme, very, moderate, late and total preterm of the regional total births were 0.14, 0.53, 0.72, 3.08 and 4.47%, with GA-specific neonatal mortality rates being 44.4, 15.8, 3.7, 1.5 and 4.3%, respectively. There were 1025 (52.8% of whole region) preterm admissions in HWCH, with significantly lower in-hospital death rate of inborn (33 of 802, 4.1%) than out-born (23 of 223, 10.3%) infants. Compared to non-HWCH, three-fold more neonates in HWCH were under critical care with higher death rate, including most extremely preterm infants. Significantly all-death risks were found for the total preterm births in birth weight < 1000 g, GA < 32 weeks, amniotic fluid contamination, Apgar-5 min < 7, and birth defects. For the hospitalized preterm infants, significantly in-hospital death risks were found in out-born of HWCH, GA < 32 weeks, birth weight < 1000 g, Apgar-5 min < 7, birth defects, respiratory distress syndrome, necrotizing enterocolitis and ventilation, whereas born in HWCH, antenatal glucocorticoids, cesarean delivery and surfactant use decreased the death risks. Conclusions The integrated data revealed the prevalence, GA-specific morbidity and mortality rate of total preterm births and their hospitalization, demonstrating the efficiency of leading referral center and whole regional perinatal-neonatal network in China. The concept and protocol should be validated in further studies for prevention of preterm birth.

Abstract
Background Disabilities caused by perinatal asphyxia will burden child health and well-being. To date, our understanding about the situation and risk factors of perinatal asphyxia-induced disabilities among Chinese children is still limited. Objectives To evaluate the prevalence and socio-demographic risk factors of disabilities caused by perinatal asphyxia among Chinese children in 2006 and compare disability trajectories across different socio-demographic status. Methods Cross-sectional data came from the 2006 China National Survey on Disability which includes a total of 616,940 children aged 0–17 years old was employed in the investigation. Perinatal asphyxia-induced disabilities were identified by following the guidance in consensus manuals. Population-weighted numbers and prevalence rates were investigated, and multivariable logistic regression was performed to evaluate associations between disabilities and socio-demographic factors. Adjusted predictions at representative values were computed to compare the disability trajectories relative to significant socio-demographic variables. Results The prevalence rate of disabilities caused by perinatal asphyxia was 7.70 per 10,000 children (95% CI: 7.01–8.39). Male (OR 1.81, 95% CI: 1.47–2.23) and low family income (OR: 1.73, 95% CI: 1.21–2.49) have higher and the increase of per additional year of age (OR: 0.89, 95% CI: 0.88–0.91) has lower probability of being disabilities caused by perinatal asphyxia. Further disability trajectories showed that differences in probability between gender and family income group were more evident before age 7 and weakened with increasing age. Conclusions Our results showed that both demographic and socioeconomic characteristics are risk factors for disabilities caused by perinatal asphyxia. Of these, gender and family income have much higher impact than other factors on the prevalence rate of disabilities caused by perinatal asphyxia at infants and young children. Multiple society sectors should increase their effort to bring about fundamental social change to prevent disabilities caused by perinatal asphyxia, especially concerning younger children and their families.

In vitro characterization and in vivo comparison of the pulmonary outcomes of Poractant alfa and Calsurf in ventilated preterm rabbits. PLoS One 2020; 15:e0230229. [PMID: 32168331 PMCID: PMC7069639 DOI: 10.1371/journal.pone.0230229] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 02/12/2020] [Indexed: 11/18/2022] Open
Abstract
Poractant alfa and Calsurf are two natural surfactants widely used in China for the treatment of neonatal respiratory distress syndrome, which are extracted from porcine and calf lungs, respectively. The purpose of this experimental study was to compare their in vitro characteristics and in vivo effects in the improvement of pulmonary function and protection of lung injury. The biophysical properties, ultrastructure, and lipid composition of both surfactant preparations were respectively analysed in vitro by means of Langmuir-Blodgett trough (LBT), atomic force microscopy (AFM), and liquid-chromatography mass-spectrometry (LC-MS). Then, as core pharmacological activity, both head-to-head (100 and 200 mg/kg for both surfactants) and licensed dose comparisons (70 mg/kg Calsurf vs. 200 mg/kg Poractant alfa) between the two surfactants were conducted as prophylaxis in preterm rabbits with primary surfactant deficiency, assessing survival time and rate and dynamic compliance of the respiratory system (Cdyn). Intrapulmonary surfactant pools, morphometric volume density as alveolar expansion (Vv), and lung injury scores were determined post mortem. AFM and LC-MS analysis revealed qualitative differences in the ultrastructure as well as in the lipid composition of both preparations. Calsurf showed a longer plateau region of the LBT isotherm and lower film compressibility. In vivo, both surfactant preparations improved Cdyn at any dose, although maximum benefits in terms of Vv and intrapulmonary surfactant pools were seen with the 200 mg/kg dose in both surfactants. The group of animals treated with 200 mg/kg of Poractant alfa showed a prolonged survival time and rate compared to untreated but ventilated controls, and significantly ameliorated lung injury compared to Calsurf at any dose, including 200 mg/kg. The overall outcomes suggest the pulmonary effects to be dose dependent for both preparations. The group of animals treated with 200 mg/kg of Poractant alfa showed a significant reduction of mortality. Compared to Calsurf, Poractant alfa exerted better effects if licensed doses were compared, which requires further investigation.

Abstract
Objectives: To describe the rates and variability of mortality and morbidity of preterm infants born in China. Methods: This prospective cohort study included infants born at <34 weeks' gestation and admitted to 25 NICUs within 7 days of birth between May 1st, 2015 and April 30th, 2016. Infants were followed until death or NICU discharge. The primary outcome was a composite of mortality or any major morbidity (sepsis, necrotizing enterocolitis, intraventricular/periventricular leukomalacia, retinopathy of prematurity, and bronchopulmonary dysplasia) in infants who received complete care following medical advice. Secondary outcomes included rate of discharge against medical advice, mortality and individual morbidities. Results: Of the 8,065 infants, 6,852 (85%) received complete care and 1,213 (15%) were discharged against medical advice. Among infants who received complete care, the rate of the composite outcome was 27% (1,827/6,852), mortality 4% (248/6,852), sepsis 14% (990/6,852), necrotizing enterocolitis 3% (191/6,550), intraventricular hemorrhage/periventricular leukomalacia 7% (422/6,307), retinopathy of prematurity 2% (67/3,349), and bronchopulmonary dysplasia 9% (616/6,852). There were significant variations between NICUs for all outcomes. Conclusions: Discharged against medical advice, mortality, and morbidity rates for preterm infants <34 weeks' gestation are high in China with significant variations between NICUs.

High risk pregnancy associated perinatal morbidity and mortality: a second birth population-based survey in Huai'an in 2015. BMC Pregnancy Childbirth 2019; 19:224. [PMID: 31269904 PMCID: PMC6609375 DOI: 10.1186/s12884-019-2323-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Accepted: 04/30/2019] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND The objective of this survey was to explore the association between pregnancy complications and perinatal outcome from regionally total birth population. METHODS In this prospectively collected data of complete birth registries from all level I-III hospitals in Huai'an in 2015, perinatal morbidity and mortality in relation to pregnancy complications and perinatal outcome were analyzed using international definitions. The results were compared with that of 2010 survey in the same region. RESULTS Of 59,424 total births in the hospitals of level I (n = 85), II (16) and III (6), delivery rate was 30.4, 40.1 and 29.5%, and rates of pregnancy complications were 12.9, 9.8 and 21.1% (average 14.1%), with antenatal corticosteroids rate in < 37 gestational weeks being 17.3, 31.0 and 39.9% (mean 36.6%), respectively. The preterm birth rate was 0.6, 2.7 and 9.5% (mean 4.06%), and the composite rate of fetal death, stillbirth, and death immediately after delivery was 0.1, 0.4 and 0.6%, respectively. By multivariable logistic regression analysis, congenital anomalies, low Apgar scores, multi-pregnancy and amniotic fluid contamination were risk factors of adverse perinatal outcomes. Despite a higher rate of pregnancy complications than in 2010 survey, perinatal and neonatal mortality continued to fall, in particular in very preterm births. The high cesarean delivery rate in non-medically indicated cases remained a challenge. CONCLUSIONS Our regional birth-population data in 2015 revealed a robust and persistent improvement in the perinatal care and management of high risk pregnancies and deliveries, which should enable more studies using similar concept and protocol for vital statistics to verify the reliability and feasibility.

Abstract
China has the largest population in the world. With rapid economic growth, the incidence of premature birth has shown an increasing trend and more neonatal intensive care units (NICUs) are being established across the country. However, there is substantial variability in clinical practice and variations in short- and long-term outcomes among patients in different NICUs. There remains a big gap between China and developed countries in terms of infant outcomes. The Evidence-based Practice for Improving Quality (EPIQ) is a successful model that has been implemented in NICUs across Canada to improve infant outcomes. We applied EPIQ in a single NICU in china and successfully reduced the incidence of ventilator-associated pneumonia, central line (CL) associated bloodstream infection (CLABSIs), and improved the breastmilk use in NICU. In the next phase, we are extending EPIQ to another 24 centers in China and have established the Chinese Neonatal Network for national collaboration, to improve infant outcomes across China.

Abstract
Objectives: We investigated the incidence and outcome of clinical and histological chorioamnionitis (CA) and the associated risk factors in an emerging provincial perinatal center in 2014-2015.Study design: Based on the suspected and proven clinical infection in the third trimester of pregnancy, placenta and accessories from singleton deliveries were routinely examined histologically. The incidence of CA and associated fetal and neonatal outcome were compared by the total deliveries.Results: Of the 14,166 deliveries in 12 months, infection and inflammation were found in 373 out of 2372 (15.7%) placentas subjected to histological examination and diagnosed as CA (2.6%). These cases were divided into four groups as histological CA only (HCA, n = 335), clinical and histological CA (HCC, n = 20), clinical CA only (CCA, n = 18) and non-CA control (CON, n = 1999). Thus, an incidence of histological CA was 2.5% (355/14 166) in this birth population. Compared to CON, HCA group was more likely to have premature rupture of membrane, antenatal antibiotic use, gestational age <34 weeks, fetal distress, positive bacterial culture from vaginal secretions, and early-onset sepsis in newborns (all p ≤ .01), which were associated with perinatal risk factors of CA. In the very preterm subgroups, more stillbirths and death at delivery and neonatal intensive care unit admissions (p < .001) were found in the CA group.Conclusions: The results suggested that histological CA was associated with early-onset sepsis and combined perinatal comorbidities which are of more diagnostic importance than clinical only CA. The placental histological examination should be routinely performed in very preterm births to better assess perinatal and neonatal outcome.

Abstract
OBJECTIVE Until now, little was known about the epidemiological characteristics of twins in China due to a lack of reliable national data. In this study, we aimed to analyze temporal trends and perinatal mortality of twins from China. METHODS Data on twins between 2007 and 2014 were obtained from the China National Population-Based Birth Defects Surveillance System. Twin and singleton deliveries after at least 28 weeks of gestation were recruited and followed until postnatal day 42. Twinning rates were defined as the number of twin individuals per 1000 births(stillbirths and live births). The Weinberg's differential method was utilized to estimate the number of monozygotic and dizygotic twins. RESULTS During 2007-2014, the twinning rate increased by 32.3% from 16.4 to 21.7 per 1000 total births with an average of 18.8‰. Among twins, both the perinatal mortality rate (26.1 per 1000 total births) and neonatal death rate (15.7 per 1000 live births) presented a downward tendency but remained at a high level. Large urban-rural and geographic disparities were identified in twinning rates, in perinatal and neonatal mortality, and in their temporal trends. CONCLUSIONS The upward trend of twinning rates in China paired with the relatively high rates of perinatal and neonatal mortality among twins highlights the need for improved perinatal care in the light of socio-demographic differences.

Abstract
Objective: This survey followed the birth population-based study conducted in 2010 in Huai'an, Jiangsu Province, with the aim to estimate perinatal-neonatal mortality and preterm birth rate in emerging regions with similar maternal-fetal and neonatal care conditions in China.Materials and methods: Data of total births in 2015 were prospectively collected by regional perinatal network collaboration in Huai'an, a subprovincial region with a population of 5,644,500 and gross domestic production of 9082 USD per capita.Results: The 59,424 birth registries (including 59,023 live births and 167 stillbirths) corresponded to a birth rate of 10.5‰ and a Male-to-female ratio of 113.7:100. All births there were from 85, 16, and 6 level I, II, and III hospitals, with a delivery rate of 30.4, 40.2, and 29.4%, respectively. Of all births, 14.1% had pregnancy-associated comorbidities and complications, 54.4% (32,226/59,190) had cesarean delivery, and multiple pregnancies and birth defects occurred in 2.1% (1,250) and 5.5‰ (324), respectively. The mean birth weight was 3448 ± 507 g with 13.9% being macrosomia, and 2.86% (1695/59,190) low birth weight. Preterm birth rate was 4.06% (2404/59,190) with a mortality rate of 8.5%. There were 94.5% recorded as healthy newborns and 5.5% (3263) requiring hospitalization after birth. The perinatal and neonatal mortality rate was 5.2‰ (167 stillbirths, 139 early neonatal deaths) and 4.0‰, respectively. Compared with the 2010 survey, these data demonstrated generally improved status of perinatal-neonatal healthcare.Conclusions: The low rates of perinatal-neonatal mortality, preterm birth and preterm mortality suggest that the concept and study protocol of perinatal-neonatal healthcare in Huai'an may serve as the benchmark for estimating regional vital statistics and perinatal and neonatal outcomes.

Abstract
OBJECTIVE The aim of this survey was to explore the relationship between admission volume and mortality of neonates with hypoxemic respiratory failure (NRF) in emerging neonatal intensive care units (NICUs). METHODS NRF from 55 NICUs were retrospectively included with death risk as the major outcome. Perinatal comorbidities, underlying disease severity, respiratory support, facility utilization, and economic burden in the early postnatal period were compared among five NICU admission volume categories defined by NRF incidence, with score for neonatal acute physiology perinatal extension II (SNAPPE-II) also assessed as initial severity. RESULTS Compared to NICUs with NRF < 50 cases/year, NRF incidence, NRF/NICU, NRF/NICU admissions, and magnitude of ventilator use were several times higher, and mortality rates 20-50% lower, in NICUs of 150-199 and ≥200 cases/year (p < .01), even after adjustment with SNAPPE-II in stratified ranges. Median SNAPPE-II values, which correlated with the death rate of NRF (r = .282, p < .001), were lower in NICUs of 150-199 and ≥200 than in <50, 50-99, and 100-149 categories (13 versus 18, p < .01). NRF mortalities were not correlated with the proportion of very low birth weight patients in each category. CONCLUSIONS Neonates in NICUs with smaller NRF admission volume and decreased magnitude of ventilator use had a higher risk of death as assessed by SNAPPE-II, which should be targeted in the quality improvement of newly established, resource-limited NICUs.

Abstract
BACKGROUND To ascertain which countries in the world have retinopathy of prematurity (ROP) screening programmes and guidelines and how these were developed. METHODS An email database was created and requests were sent to ophthalmologists in 141 nations to complete an online survey on ROP screening in their country. RESULTS Representatives from 92/141 (65%) countries responded. 78/92 (85%) have existing ROP screening programmes, and 68/78 (88%) have defined screening criteria. Some countries have limited screening and those areas which have no screening or for which there is inadequate knowledge are mainly Southeast Asia, Africa and some former Soviet states. DISCUSSION With the increasing survival of premature babies in lower-middle-income and low-income countries, it is important to ensure that adequate ROP screening and treatment is in place. This information will help organisations focus their resources on those areas most in need.

Abstract
OBJECTIVE We evaluated the efficacy of surfactant therapy and assisted ventilation on morbidity and mortality of neonates with birth weight (BW) ⩾1500 g and hypoxemic respiratory failure (HRF). STUDY DESIGN We retrospectively analyzed 5650 patients with BW ⩾1500 g for incidence, management and outcome of HRF, defined as acute hypoxemia requiring mechanical ventilation and/or nasal continuous positive airway pressure ⩾24 h. The patients were allocated into groups of moderate preterm (1735, 30.7%), late preterm (1431, 25.4%), early term (ETM, 986, 17.5%), full term (1390, 24.6%) and post term (79, 1.4%), with gestational age ⩽33, 34 to 36, 37 to 38, 39 to 41 and ⩾42 weeks, respectively. RESULTS In the five groups, 66.9, 42, 21.6, 12.8 and 5.1% had respiratory distress syndrome (RDS). For pneumonia/sepsis and meconium aspiration syndrome (MAS), the proportion was 13.8%, 25.4%, 38.0%, 52.5% and 76.0%, respectively. Surfactant was given to 21.9% (n=1238) of HRF and 51.2% (n=1108) of RDS. Survival rates of RDS were 82.2%, 87.8%, 84.5%, 77.1% and 75.0%, respectively (numbers needed to treat was 8 to 11 for surfactant benefit). Overall mortality rate of HRF was 21%, or 17.9%, 14.7%, 25.6%, 28.9% and 39.2%, respectively. Mortalities of MAS and pneumonia/sepsis were 29.4 and 27.6%. Relative risk of death was associated with initial disease severity, female gender, mechanical ventilation and congenital anomalies by multivariate logistic regression analysis. CONCLUSION Surfactant was effective for infants with RDS and BW ⩾1500 g, and different incidences and outcome of HRF among GA groups reflected standard of perinatal and respiratory care in emerging neonatal intensive care unit network.

Abstract
OBJECTIVES To summarize academic productivity of neonatal medicine in China and explore its relationship with health care workforce and activities. METHODS We retrospectively extracted data from national key clinical subspecialty proposals, and used accessible databases as Science Citation Index (SCI), PubMed, and National Natural Science Foundation of China. RESULTS Between 2008 and 2010, 61 newborn units at the most advanced level in 31 cities from 28 of 31 provincial districts in mainland China were included. Fifty-two national or international projects and 111 provincial projects were conducted. A total of 171 articles were listed in the SCI database; 23 patents were registered. There were 83 oral presentations in international conferences abroad. One national and 40 provincial government awards were received. Health workforce indexes, such as physicians with MD&PhD degrees, were significantly related to academic productivity. National or international projects (β = .285, p <.001; 95% CI = 0.179, 0.391) and the number of newborn beds (β = .005, p = .016; 95% CI = 0.001, 0.008) were two underlying factors to determine government awards (adjusted R2 = .426). The 10 main cities for neonatal medicine research were also listed. CONCLUSION In this study, we established the baseline information on neonatal medicine research in China, which could provide information for further practice.

Abstract
Previous surveys of neonatal medicine in China have not collected comprehensive information on workforce, investment, health care practice, and disease expenditure. The goal of the present study was to develop a national database of neonatal care units and compare present outcomes data in conjunction with health care practices and costs. We summarized the above components by extracting data from the databases of the national key clinical subspecialty proposals issued by national health authority in China, as well as publicly accessible databases. Sixty-one newborn clinical units from provincial or ministerial hospitals at the highest level within local areas in mainland China, were included for the study. Data were gathered for three consecutive years (2008–2010) in 28 of 31 provincial districts in mainland China. Of the 61 newborn units in 2010, there were 4,948 beds (median = 62 [IQR 43–110]), 1,369 physicians (median = 22 [IQR 15–29]), 3,443 nurses (median = 52 [IQR 33–81]), and 170,159 inpatient discharges (median = 2,612 [IQR 1,436–3,804]). During 2008–2010, the median yearly investment for a single newborn unit was US$344,700 (IQR 166,100–585,800), median length of hospital stay for overall inpatient newborns 9.5 (IQR 8.2–10.8) days, median inpatient antimicrobial drug use rate 68.7% (IQR 49.8–87.0), and median nosocomial infection rate 3.2% (IQR1.7–5.4). For the common newborn diseases of pneumonia, sepsis, respiratory distress syndrome, and very low birth weight (<1,500 grams) infants, their lengths of hospital stay, daily costs, hospital costs, ratios of hospital cost to per-capita disposable income, and ratios of hospital cost to per-capita health expenditure, were all significantly different across regions (North China, Northeast China, East China, South Central China, Southwest China, and Northwest China). The survival rate of extremely low birth weight (ELBW) infants (Birth weight <1,000 grams) was 76.0% during 2008–2010 in the five hospitals where each unit had more than 20 admissions of ELBW infants in 2010; and the median hospital cost for a single hospital stay in ELBW infants was US$8,613 (IQR 8,153–9,216), which was 3.0 times (IQR 2.0–3.2) the average per-capita disposable income, or 63 times (IQR 40.3–72.1) the average per-capita health expenditure of local urban residents in 2011. Our national database provides baseline data on the status of advanced neonatal medicine in China, gathering valuable information for quality improvement, decision making, longitudinal studies and horizontal comparisons.

Early inhaled nitric oxide in preterm infants <34 weeks with evolving bronchopulmonary dysplasia. J Perinatol 2016; 36:883-9. [PMID: 27442155 DOI: 10.1038/jp.2016.112] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Revised: 04/08/2016] [Accepted: 04/18/2016] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To investigate whether early treatment with inhaled nitric oxide (iNO) could prevent bronchopulmonary dysplasia (BPD) in very preterm infants. STUDY DESIGN A non-randomized, controlled trial was conducted prospectively in 27 neonatal intensive care units over 12 months. Preterm infants with gestational age <34 weeks and after 7 days of life, who received invasive mechanical ventilation (MV) or nasal continuous positive airway pressure for >2 days, were treated either with low-dose iNO (from 5 as initial dose to 2 parts per million as maintenance dose for ⩾7 days, n=162) or as non-placebo control (n=240). Primary outcome was the incidence of moderate-to-severe BPD at 36 weeks postmenstrual age and/or death before discharge. Secondary outcomes were major complications. RESULTS iNO was started on average on day 19 of life (median duration 18 days, range 7 to 55 days). Rate of survival without BPD was significantly lower in the iNO than in the control group, whereas overall rates of BPD, death and major complications were similar between the two groups. Infants who started MV and iNO on postnatal days 15 to 21 had significantly increased survival without BPD (47.6% vs 17.1%, P=0.03, relative risk 2.7, 95% confidence interval 1.1 to 6.5). Additionally, pooled data from both groups showed that rates of perinatal co-morbidities and postnatal complications were higher in BPD infants than in non-BPD infants. The overall incidence of BPD was 55.6% and 75.9% for birth weight <1500 and <1000 g, respectively, or 1.6% for the total population <34 weeks of gestation admitted through the network. CONCLUSION Treatment with low-dose iNO did not decrease the overall risk of BPD and death nor showed adverse effects in short-term morbidities among very preterm infants. The benefit of delayed iNO treatment on BPD warrants further studies.
