Metabolic bone disease of prematurity (MBDP) is a systemic bone disease with a reduction in bone mineral content due to disorder of calcium and phosphorus metabolism. There is still a lack of in-depth research and systematic understanding of MBDP in China, and there are many irregularities in clinical management of this disease. Based on relevant studies in China and overseas, Grading of Recommendations Assessment, Development and Evaluation was used to develop the expert consensus on the clinical management of MBDP, which provides recommendations from the following five aspects: high-risk factors, screening/diagnosis, prevention, treatment, and post-discharge follow-up of MBDP, so as to provide relevant practitioners with recommendations on the clinical management of MBDP to reduce the incidence rate of MBDP and improve its short- and long-term prognosis.早产儿代谢性骨病(metabolic bone disease of prematurity,MBDP)是由于机体钙磷代谢紊乱导致骨矿物质含量减少的全身性骨骼疾病。我国目前对MBDP尚缺乏深入研究和系统认识,在临床管理方面存在很多不规范之处。现基于国内外相关研究,采用证据推荐分级的评估、制定与评价方法(Grading of Recommendations Assessment,Development and Evaluation),制定MBDP临床管理专家共识,从MBDP的高危因素、筛查/诊断、预防、治疗及出院后随访等5个方面提出推荐意见,旨在为相关从业人员提供 MBDP临床管理的建议,以减少MBDP的发生及改善其近远期预后。.

- Abstract
Objective To investigate the status of pubertal development in children born with assisted reproductive technology (ART). Methods A retrospective analysis was performed on the pubertal development data of children born with ART in Peking University Third Hospital from 1994 to 2003 (ART group). The data in the cross-sectional study "Reports on the Physical Fitness and Health Research of Chinese School Students in 2010" were used as a control. The age at menarche and the age at spermarche were compared between the two groups. The status of pubertal development in the overweight and obese children in the ART group was evaluated to investigate the correlation between pubertal development and body mass index (BMI). Results A total of 200 children born with ART were enrolled in this study, and 72 of them (41 males and 31 females) completed the survey (response rate=36.0%). In the ART group, the mean age at spermarche and the mean age at menarche were 13.9 years (95%CI: 13.7-14.3 years) and 12.2 years (95%CI: 11.8-12.6 years), respectively. There were no significant differences in the age at spermarche and the age at menarche between the ART and control groups (P>0.05). In the ART group, there were no significant differences in the age at spermarche and the age at menarche between the overweight and obese children and the normal weight children (P>0.05). There were also no significant differences in overweight rate and obesity rate between the children in the ART group and the adolescents in Beijing (P>0.05). In the ART group, there was no significant correlation between the age at spermarche or menarche and BMI (P>0.05). Conclusions No delayed or precocious puberty is observed in children born with ART. This is consistent with the normal control data. And there is no significant correlation between pubertal development and BMI in children born with ART. [ABSTRACT FROM AUTHOR]

- Abstract
The aim of this study was to develop a real-time risk prediction model for extrauterine growth retardation (EUGR). A total of 2514 very preterm infants were allocated into a training set and an external validation set. The most appropriate independent variables were screened using univariate analysis and Lasso regression with tenfold cross-validation, while the prediction model was designed using binary multivariate logistic regression. A visualization of the risk variables was created using a nomogram, while the calibration plot and receiver operating characteristic (ROC) curves were used to calibrate the prediction model. Clinical efficacy was assessed using the decision curve analysis (DCA) curves. Eight optimal predictors that namely birth weight, small for gestation age (SGA), hypertensive disease complicating pregnancy (HDCP), gestational diabetes mellitus (GDM), multiple births, cumulative duration of fasting, growth velocity and postnatal corticosteroids were introduced into the logistic regression equation to construct the EUGR prediction model. The area under the ROC curve of the training set and the external verification set was 83.1% and 84.6%, respectively. The calibration curve indicate that the model fits well. The DCA curve shows that the risk threshold for clinical application is 0-95% in both set. Introducing Birth weight, SGA, HDCP, GDM, Multiple births, Cumulative duration of fasting, Growth velocity and Postnatal corticosteroids into the nomogram increased its usefulness for predicting EUGR risk in very preterm infants., (© 2024.

- Abstract
Background: Necrotizing enterocolitis (NEC) is a serious gastrointestinal disease, primarily affects preterm newborns and occurs after 7 days of life (late-onset NEC, LO-NEC). Unfortunately, over the past several decades, not much progress has been made in its treatment or prevention. This study aimed to analyze the risk factors for LO-NEC, and the impact of LO-NEC on short-term outcomes in very preterm infants (VPIs) with a focus on nutrition and different onset times., Method: Clinical data of VPIs were retrospectively collected from 28 hospitals in seven different regions of China from September 2019 to December 2020. A total of 2509 enrolled VPIs were divided into 2 groups: the LO-NEC group and non-LO-NEC group. The LO-NEC group was divided into 2 subgroups based on the onset time: LO-NEC occurring between 8 ~ 14d group and LO-NEC occurring after 14d group. Clinical characteristics, nutritional status, and the short-term clinical outcomes were analyzed and compared among these groups., Results: Compared with the non-LO-NEC group, the LO-NEC group had a higher proportion of anemia, blood transfusion, and invasive mechanical ventilation (IMV) treatments before NEC; the LO-NEC group infants had a longer fasting time, required longer duration to achieve the target total caloric intake (110 kcal/kg) and regain birthweight, and showed slower weight growth velocity; the cumulative dose of the medium-chain and long-chain triglyceride (MCT/LCT) emulsion intake in the first week after birth was higher and breastfeeding rate was lower. Additionally, similar results including a higher proportion of IMV, lower breastfeeding rate, more MCT/LCT emulsion intake, slower growth velocity were also found in the LO-NEC group occurring between 8 ~ 14d when compared to the LO-NEC group occurring after 14 d (all (P < 0.05). After adjustment for the confounding factors, high proportion of breastfeeding were identified as protective factors and long fasting time before NEC were identified as risk factors for LO-NEC; early feeding were identified as protective factors and low gestational age, grade III ~ IV neonatal respiratory distress syndrome (NRDS), high accumulation of the MCT/LCT emulsion in the first week were identified as risk factors for LO-NEC occurring between 8 ~ 14d. Logistic regression analysis showed that LO-NEC was a risk factor for late-onset sepsis, parenteral nutrition-associated cholestasis, metabolic bone disease of prematurity, and extrauterine growth retardation., Conclusion: Actively preventing premature birth, standardizing the treatment of grade III ~ IV NRDS, and optimizing enteral and parenteral nutrition strategies may help reduce the risk of LO-NEC, especially those occurring between 8 ~ 14d, which may further ameliorate the short-term clinical outcome of VPIs., Trial Registration: ChiCTR1900023418 (26/05/2019)., (© 2024.

- Abstract
Objectives: To compare the impact of two types of fat emulsion on clinical outcomes in preterm infants with varying duration of parenteral nutrition (PN)., Methods: Preterm infants meeting the inclusion criteria were randomly assigned to two groups: medium/long-chain triglyceride fat emulsion (referred to as MCT/LCT) group or multi-oil fat emulsion (containing soybean oil, medium-chain triglycerides, olive oil, and fish oil; referred to as SMOF) group. The infants were stratified into groups based on the duration of PN (15-21 days, 22-28 days, and ≥29 days). Clinical characteristics, nutritional status, biochemical indicators, and clinical outcomes were compared between the two groups., Results: Compared with the MCT/LCT group, the SMOF group had lower peak levels of triglyceride during the hospital stay in preterm infants with PN of 15-21 days, 22-28 days, and ≥29 days, respectively ( P <0.05). Logistic regression trend analysis showed that with a longer duration of PN, the risk of parenteral nutrition-associated cholestasis (PNAC) and bronchopulmonary dysplasia (BPD) significantly increased in the MCT/LCT group ( P <0.05), while the risk of brain injury did not significantly change ( P >0.05). In the SMOF group, the risks of PNAC and BPD did not significantly change with a longer duration of PN ( P >0.05), but the risk of brain injury significantly decreased ( P =0.006)., Conclusions: Compared to MCT/LCT, SMOF have better lipid tolerance. With a longer duration of PN, SMOF does not increase the risks of PNAC and BPD and had a protective effect against brain injury. This suggests that in preterm infants requiring long-term PN, the use of SMOF is superior to MCT/LCT.

- Abstract
Objectives: To study the effects of infantile positional plagiocephaly on the growth and neural development., Methods: A retrospective study was conducted on the medical data of 467 children who underwent craniographic examination and were followed up to 3 years of age in Peking University Third Hospital from June 2018 to May 2022. They were divided into four groups: mild positional plagiocephaly ( n =108), moderate positional plagiocephaly ( n =49), severe positional plagiocephaly ( n =12), and normal cranial shape ( n =298). The general information of the four groups and the weight, length, head circumference, visual acuity screening results, hearing test results, and the scores of Pediatric Neuropsychological Developmental Scales/Gesell Developmental Schedules of the four groups from 6 to 36 months old were compared., Results: The rates of adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping posture in the mild, moderate, and severe positional plagiocephaly groups were higher than the normal cranial group ( P <0.05). There was no significant difference in weight, length, and head circumference among the four groups at 6, 12, 24 and 36 months of age ( P >0.05). The incidence rate of abnormal vision in the severe positional plagiocephaly group was higher than that in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups at 24 and 36 months of age ( P <0.05). The scores of the Pediatric Neuropsychological Developmental Scales at 12 and 24 months of age and the scores of the Gesell Developmental Schedules at 36 months of age in the severe positional plagiocephaly group were lower than those in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups, but the difference was not statistically significant ( P >0.05)., Conclusions: Adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping position may be associated with infantile positional plagiocephaly. Mild or moderate positional plagiocephaly has no significant impact on the growth and neural development of children. Severe positional plagiocephaly have adverse effects on the visual acuity. However, it is not considered that severe positional plagiocephaly can affect the neurological development.

- Abstract
Objectives: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China., Methods: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group ( n =1 189) and non-EUGR ( n =1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined., Results: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR ( P <0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR ( P <0.05)., Conclusions: It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

- Abstract
Objectives: To study the effect of surgical treatment on prognosis in preterm infants with obstructive hydrocephalus., Methods: A retrospective analysis was performed on the medical data of 49 preterm infants with obstructive hydrocephalus. According to the treatment regimen, they were divided into two groups: surgical treatment ( n =12) and conservative treatment ( n =37). The drainage methods, drainage complications, and eventual shunt outcome were analyzed in the surgical treatment group. The two groups were compared in terms of the etiology of hydrocephalus and prognosis., Results: Among the 49 preterm infants with obstructive hydrocephalus, severe intracranial hemorrhage (37 cases; 76%) and central nervous system infection (10 cases, 20%) were the main causes of hydrocephalus. There was no significant difference in the composition of etiology between the two groups ( P >0.05). In the surgical treatment group, 4 infants were treated with ventriculosubgaleal shunt and 8 were treated with Ommaya reservoir. One infant had secondary infection and 8 infants eventually underwent ventriculoperitoneal shunt. The surgical treatment group had a significantly higher survival rate than the conservative treatment group ( P <0.05). As for the 37 preterm infants with severe intracranial hemorrhage, the surgical treatment group had a significantly higher proportion of infants with normal neurodevelopment than the conservative treatment group ( P <0.05). As for the 10 preterm infants with central nervous system infection, neurodevelopmental abnormalities were observed in each of the two groups., Conclusions: Surgical treatment can improve the survival rate of preterm infants with obstructive hydrocephalus and the prognosis of preterm infants with severe intracranial hemorrhage.

- Abstract
Objective: To study the risk factors for the first ventilator weaning failure and the relationship between the weaning failure and prognosis in preterm infants receiving invasive mechanical ventilation., Methods: A retrospective analysis was performed for the preterm infants who were admitted to the Neonatal Intensive Care Unit of Peking University Third Hospital and received mechanical ventilation within 72 hours after birth. According to whether reintubation was required within 72 hours after the first weaning, the infants were divided into a successful weaning group and a failed weaning group., Results: A total of 282 preterm infants were enrolled, and there were 43 infants (15.2%) in the failed weaning group. Compared with the successful weaning group, the failed weaning group had significantly lower gestational age and birth weight ( P < 0.05), a significantly higher rate of intubation in the delivery room ( P < 0.05), and a significantly higher proportion of infants with patent ductus arteriosus (PDA; diameter ≥ 2.5 mm) ( P < 0.05). Use of ≥ 2 vasoactive agents before ventilator weaning ( OR =2.48, 95% CI :1.22-5.03, P < 0.05) and PDA (≥ 2.5 mm) ( OR =4.54, 95% CI :2.02-10.24, P < 0.05) were risk factors for ventilator weaning failure. Compared with the successful weaning group, the failed weaning group had significantly higher incidence rates of ventilator-associated pneumonia, moderate-to-severe bronchopulmonary dysplasia, and sepsis ( P < 0.05). The oxygen inhalation time and hospital stay in the failed weaning group were significantly longer than those in the successful weaning group ( P < 0.05)., Conclusions: Use of ≥ 2 vasoactive agents before ventilator weaning and PDA (≥ 2.5 mm) are risk factors for ventilator weaning failure, and ventilator weaning failure may be associated with adverse outcomes in hospitalized preterm infants.

- Abstract
Objective: To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants., Methods: The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP., Results: The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation ( P < 0.05). Compared with the non-MBDP group, the MBDP group had significantly higher incidence rates of neonatal sepsis, anemia, hypocalcemia, and retinopathy of prematurity ( P < 0.05). The MBDP group had a significantly lower mean feeding speed, a significantly higher age when reaching total enteral feeding, and a significantly longer duration of parenteral nutrition ( P < 0.05). The use rate of caffeine citrate in the MBDP group was significantly higher, but the use rate of erythropoietin was significantly lower than that in the non-MBDP group ( P < 0.05). The multivariate logistic regression analysis showed that gestational age < 32 weeks, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis were risk factors for MBDP ( P < 0.05)., Conclusions: A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

- Abstract
A girl, aged 15 years, was admitted due to sudden convulsion once and multiple pulmonary nodules on lung CT. Acrocyanosis or acropachy/toe deformity was not observed. Laboratory examinations showed an increase in hemoglobin (162 g/L) and a reduction in arterial partial pressure of oxygen (61.5 mm Hg). Lung CT showed irregular slightly high-density nodules in the middle lobe of the right lung, and contrast-enhanced CT scan showed obvious enhancement with thick vascular shadow locally. An investigation of medical history revealed that the girl's mother had a history of epistaxis and resection of pulmonary mass and the girl presented with tongue telangiectasia. The girl was diagnosed with hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformation. she was given interventional embolization therapy. Transcutaneous oxygen saturation reached 98% without oxygen inhalation on the day after surgery. Pulmonary angiography at 3 months after surgery showed the recurrence of pulmonary vascular malformation, and embolization of pulmonary arterial fistula was not performed since the guide wire could not enter the branch artery. There was still a need for long-term follow-up.

- Abstract
Objective: To study the clinical features of pericardial effusion caused by central venous catheterization in preterm infants., Methods: A retrospective analysis was performed on 11 preterm infants with pericardial effusion caused by central venous catheterization. Their catheterization features, manifestations, treatment, and prognosis were analyzed., Results: A total of 11 preterm infants (11/2 599, 0.42%) developed pericardial effusion, with a mean gestational age of (30.1±2.6) weeks and a mean birth weight of (1 240±234) g. Pericardial effusion mostly occurred within 4 days after central venous catheterization (10 cases, 91%). The main manifestations included poor response (6/11, 55%), cyanosis (5/11, 45%), increased respiratory rate (6/11, 55%), increased heart rate (6/11, 55%), aggravated dyspnea (5/11, 45%), and muffled heart sound (5/11, 45%). At the time of disease progression, 7 preterm infants (64%) had a deep position of the end of the catheter, 3 preterm infants (27%) had a correct position, and 1 preterm infant (9%) had a shallow position. Five preterm infants (45%) experienced cardiac tamponade, among whom 4 underwent pericardiocentesis. Seven preterm infants were given conservative medical treatment. Among the 11 children, 2 (18%) died and 9 (82%) improved., Conclusions: Pericardial effusion caused by central venous catheterization mostly occurs in the early stage of catheterization and has critical clinical manifestations. Pericardiocentesis is required for cardiac tamponade, and early diagnosis and intervention can effectively improve prognosis.

- Abstract
Objective: To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases., Methods: Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases., Results: A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, P =0.033). The multivariate logistic regression analysis showed that breastfeeding was an independent protective factor against infectious diseases ( OR =0.534, P =0.004), while male sex, premature rupture of membranes, gestational diabetes mellitus, and asphyxia were risk factors for infectious diseases ( OR =1.328, 5.386, 1.535, and 2.353 respectively, P < 0.05)., Conclusions: Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

- Abstract
The microbiome in neonates is affected by many factors such as mode of birth and feeding pattern, and homeostasis or disorder of microbiome is associated with various neonatal diseases. Preterm infants have a gestational age of <37 weeks at birth, with immature development and different colonization of bacteria from full-term infants. The research on the characteristics of microbiome and their association with diseases in preterm infants can provide new ideas for the treatment of neonatal diseases. This article reviews the characteristics of intrauterine microbiome, dermal microbiome, oral microbiome, stomach microbiome, intestinal microbiome, and environmental microbiome and their association with common diseases in preterm infants.

- Abstract
Objective: To study the risk factors and treatment outcome of hypothyroidism in very low birth weight/extremely low birth weight (VLBW/ELBW) infants., Methods: The VLBW/ELBW infants who were diagnosed with hypothyroidism from September 2018 to December 2019 were enrolled as the case group (n=29). The children with normal thyroid function, matched at a ratio of 1 : 3, were enrolled as the control group (n=87). Clinical features were compared between the two groups. The correlation of thyroid function with gestational age and birth weight and the risk factors for hypothyroidism were analyzed., Results: A total of 162 VLBW/ELBW infants who met the inclusion criteria were enrolled, with 29 infants in the case group (an incidence rate of hypothyroidism of 17.9%). The lower the birth weight, the higher the incidence rate of hypothyroidism (P<0.05). Triiodothyronine (T3) and free T3 were positively correlated with gestational age (P<0.05). T3 and free thyroxine were positively correlated with birth weight (P<0.05). Small for gestational age, multiple birth, maternal age ≥ 35 years, and use of dopamine were independent risk factors for hypothyroidism (P<0.05). In the case group, 16 infants were treated with levothyroxine (5-10 μg/kg daily), and the thyroid function returned to normal after 2 weeks of treatment., Conclusions: There is a high incidence rate of hypothyroidism in VLBW/ELBW infants. Small for gestational age, multiple birth, advanced maternal age, and use of dopamine are risk factors for hypothyroidism. The infants treated with levothyroxine should be followed up regularly to ensure an appropriate dose.

- Abstract
Inadequate nutrition supply in the early stage after birth is a risk factor for the development of bronchopulmonary dysplasia (BPD) in preterm infants, and it is also closely associated with the progression and clinical outcome of BPD. Optimized nutritional support is of great importance to reduce the incidence and severity of BPD and promote lung development and neurological prognosis. Based on the relevant studies in China and overseas, the expert consensus on BPD nutrition management is developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method. The consensus includes the following seven aspects: the importance of nutrition in BPD, fluid intake, energy intake, enteral nutrition, parenteral nutrition, post-discharge nutrition, and nutrition monitoring and evaluation.

- Abstract
Objective: To study the clinical features, etiology, treatment, and prognosis of neonatal chylous effusions., Methods: A retrospective analysis was performed for the clinical data of 21 neonates with chylous effusions., Results: Among these 21 neonates, 13 had chylothorax, 2 had chyloperitoneum, 2 had chylopericardium, and 4 had chylous polyserositis. Five neonates with congenital chylous effusions were enrolled as the congenital group, which mostly occurred in the fetal period, and symptoms were observed shortly after birth. Sixteen neonates with acquired chylous effusions were enrolled as the acquired group, and the symptoms mainly appeared within 1 week after central venous catheterization (in 14 neonates) or appeared together with sepsis (in 2 neonates). Compared with the acquired group, the congenital group had significantly higher specific gravity, white blood cell count, monocyte percentage, and albumin level in effusions (P<0.05) and significantly lower levels of glucose and triglyceride (P<0.05). Central venous catheterization-induced chylous effusions were mainly associated with inappropriate position, displacement damage, and hypertonicity. Conservative treatment was the main treatment method for the neonates with chylous effusions (in 20 children), with a response rate of 85%. Compared with the acquired group, the congenital group had a significant higher proportion of neonates receiving special formula feeding, a significantly lower proportion of neonates with extubation, and a significantly longer time to the absorption of effusions (P<0.05)., Conclusions: The time to the occurrence of symptoms and clinical manifestations vary with disease etiology and location in neonates with chylous effusions. Neonates with acquired chylous effusions may experience hypertonic solution effusion due to vascular injury. Conservative treatment has a marked clinical effect on neonatal chylous effusions. It appears to be more difficult to treat neonates with congenital chylous effusions than those with acquired chylous effusion.

- Abstract
Objective: To identify risk factors for minimally invasive surfactant administration (MISA) failure in the treatment of preterm infants with respiratory distress syndrome (RDS) and the influence of MISA failure on neonatal outcome., Methods: A retrospective analysis was performed for the clinical data of 148 preterm infants with a gestational age of ≤32 weeks and a clinical diagnosis of RDS, who were admitted to the neonatal intensive care unit of eight tertiary hospitals in Beijing, Tianjin and Hebei Province from July 1, 2017 to December 31, 2018 and were treated with MISA (bovine pulmonary surfactant, PS). According to whether MISA failure (defined as the need for mechanical ventilation within 72 hours after MISA) was observed, the infants were divided into two groups: MISA failure group (n=16) and MISA success (n=132). A logistic regression analysis was used to investigate the risk factors for MISA failure and its influence on neonatal outcome., Results: The MISA failure rate was 10.8% (16/148). The logistic regression analysis showed that a high incidence rate of grade >II RDS before PS administration, low mean arterial pressure and high pulse pressure before administration, a low dose of initial PS administration, and long injection time and operation time were the risk factors for MISA failure (OR=5.983, 1.210, 1.183, 1.055, 1.036, and 1.058 respectively, P<0.05). After the control for the above risk factors, the logistic regression analysis showed that the MISA failure group had a significantly higher incidence rate of bronchopulmonary dysplasia (BPD) (OR=8.537, P<0.05)., Conclusions: A high grade of RDS, a low mean arterial pressure, and a high pulse pressure before administration are independent risk factors for MISA failure, and a low dose of initial PS administration, a long injection time, and a long operation time may increase the risk of MISA failure. MISA failure may increase the incidence rate of BPD in preterm infants.

- Abstract
Objective: To study the clinical features and pathogenic bacteria of late-onset sepsis (LOS) in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants., Methods: Among the VLBW/ELBW infants with a gestational age of <32 weeks who were admitted to the hospital between January 2012 and December 2016, those with LOS were enrolled as the LOS group, and those without sepsis were matched for the infant with LOS in gestational age were enrolled as the control group. According to the presence or absence of in-hospital death, the LOS group was further divided into a death subgroup and a survival subgroup. Risk factors for LOS, clinical features, distribution of pathogenic bacteria, drug resistance, and high-risk factors for LOS-related death were analyzed., Results: A total of 513 VLBW/ELBW infants were enrolled, and there were 65 infants in the LOS group and 130 in the control group. The incidence rate of LOS was 12.7%. In the LOS group, 6 infants died and 59 survived. Compared with the control group, the LOS group had a significantly lower birth weight (P<0.05) and significantly longer indwelling time of peripherally inserted central catheter (PICC), duration of mechanical ventilation, and length of hospital stay (P<0.05). Compared with the control group, the LOS group had a significantly higher proportion of small-for-gestational-age infants, infants undergoing mechanical ventilation, infants with neonatal necrotizing enterocolitis, or infants who died (P<0.05). Low birth weight, small-for-gestational-age infant, and long indwelling time of PICC were independent risk factors for LOS in VLBW/ELBW infants (OR=1.396, 2.550, and 1.068 respectively, P<0.05). Purulent meningitis was an independent risk factor for LOS-related death in VLBW/ELBWIs infants (OR=13.443, P<0.05). A total of 65 strains of pathogenic bacteria were cultured in the LOS group, among which there were 39 strains (60%) of Gram-negative bacteria, including 15 strains producing extended spectrum beta-lactamases (ESBLs), and antibiotics were applied for 67% (10/15) of the ESBL strains within 2 weeks before the onset of LOS. The rate of antibiotic use for ESBL strains was significantly higher than that for non-resistant strains [67% (10/15) vs 29% (7/24); P<0.05]., Conclusions: Low birth weight, SGA infant, and long indwelling time of PICC are independent risk factors for LOS in VLBW/ELBW infants, and death tends to occur in LOS infants with purulent meningitis. Most pathogenic bacteria of LOS are Gram-negative bacteria, and use of antibiotics within 2 weeks before disease onset may increase the risk of ESBL strain infection.

- Abstract
Objective: To investigate the physical development, incidence of common respiratory diseases, and motor development during infancy in preterm infants with bronchopulmonary dysplasia (BPD)., Methods: A retrospective analysis was performed on the clinical features and infantile outcomes of preterm infants with BPD who were admitted to the neonatal intensive care unit between January 2012 and December 2015. Preterm infants without BPD were used as controls who were admitted to the neonatal intensive care unit during the same period and had similar gestational age and birth weight. Physical development, number of hospital stays, the incidences of pneumonia and wheezing, and motor development during infancy were compared between the two groups., Results: Compared with the control group, BPD infants had a significantly higher incidence of extrauterine growth retardation at discharge (48% vs 41%; P<0.05); BPD infants were more susceptible to pneumonia, wheezing, eczema and rhinitis; BDP infants also had a significantly higher number of readmissions due to respiratory tract infection (P<0.05). BPD infants had a significantly smaller head circumference than the control group at corrected ages of 3, 6, and 12 months (P<0.05). BPD infants had significantly delayed gross, fine, and overall motor development than the control group at corrected ages of 6 and 9 months (P<0.05)., Conclusions: Infants with BPD are susceptible to extrauterine growth retardation at discharge. Their head circumference growth is relatively slow. They are susceptible to pneumonia and wheezing during infancy. Moreover, they have delayed motor development when compared with those without BPD at corrected ages of 6 and 9 months.

Objective: To study the clinical features, etiology and prognosis of neonates with nonimmune hydrops fetalis (NIHF)., Methods: A retrospective analysis was performed for the clinical data and outcomes of 23 neonates with NIHF., Results: Of the 23 neonates with NIHF, 18 (78%) were preterm infants and 5 (22%) were full-term infants; 12 (52%) had birth asphyxia (including 5 cases of severe asphyxia). As for the causes of NIHF, 8 neonates (35%) had twin-twin transfusion syndrome (TTTS), 3 (13%) had cardiovascular malformation, 3 (13%) had parvovirus B19 infection, 2 (9%) had congenital chylothorax, 1 (4%) had Turner syndrome, 1 (4%) had Coxsackie virus infection, and 5 (22%) had unknown etiology. Of the 23 neonates, 13 achieved clinical cure, 10 died, resulting in a neonatal mortality rate of 43%. Compared with the survival group, the death group had a significantly higher proportion of preterm infants or infants with asphyxia, 5-minute Apgar score<8 or heart failure (100%/100%/60%/60% vs 62%/15%/8%/8%; P<0.05)., Conclusions: Birth asphyxia is common in neonates with NIHF. The neonates with a lower gestational age, a more serious asphyxia or heart failure have a higher risk of death in the neonatal period. Being the recipient of TTTS is a major cause of NIHF.

Objective: To investigate the incidence of neonatal birth trauma in the department of obstetrics in a single-center medical institution and the risk factors for neonatal birth trauma., Methods: The maternal and infant medical records of all full-term singleton neonates delivered in the Department of Obstetrics, Peking University International Hospital, from October 2015 to September 2018 were collected. The neonates with birth trauma were assigned to case group, and those without birth trauma were assigned to control group. The risk factors for neonatal birth trauma were identified by multivariate logistic regression analysis., Results: Of the 4 682 full-term singleton neonates delivered during the study period, 201 (4.29%) were diagnosed with birth trauma. The most frequent type of birth trauma was cephalohematoma (81.7%), followed by facial nerve palsy (9.1%). The multivariate logistic regression analysis identified vaginal delivery, forceps-assisted delivery, induction of labor by oxytocin, premature rupture of membranes and a large neonatal head circumference as the risk factors for birth trauma (OR=5.020, 23.294, 1.409, 1.928 and 2.295 respectively; P<0.05)., Conclusions: The most frequent type of neonatal birth trauma is cephalohematoma. Vaginal delivery, forceps-assisted delivery, induction of labor by oxytocin, premature rupture of membranes and a large neonatal head circumference may increase the risk of neonatal birth trauma, and forceps-assisted delivery is the strongest independent risk factor for birth trauma.

- Abstract
A boy aged 2 months (born at 36 weeks of gestation) was admitted due to cough and dyspnea. After admission, he was found to have persistent hypertension, proteinuria, and persistent convulsion, and imaging examination showed extensive calcification of the aorta and major branches and stenosis of local lumens of the abdominal aorta and the right renal artery with increased blood flow velocity. The boy was admitted during the neonatal period due to wet lung and pulmonary arterial hypertension and was found to have hypertension and proteinuria. High-throughput whole-exome sequencing was performed and found two compound heterozygous mutations in the ENPP1 gene from his parents, c.130C>T (p.Q44X) and c.1112A>T (p.Y371F). c.130C>T was a nonsense mutation, which could cause partial deletion of protein from 44 amino acids, and was defined as a primary pathogenic mutation. c.1112A>T was a missense mutation which had been reported as a pathogenic mutation associated with idiopathic infantile arterial calcification (IIAC). Therefore, he was diagnosed with IIAC. He was given phosphonate drugs, antihypertensive drugs, anticonvulsion treatment, and respiratory support. Blood pressure was maintained at the upper limit of normal value. There was no deterioration of arterial calcification. It is concluded that IIAC should be considered for infants with persistent hypertension and extensive vascular calcification, and imaging and genetic examinations should be performed as early as possible to make a confirmed diagnosis.
