RESUMO
PURPOSE: Anterior release for Scheuermann's disease was considered an important technique for decades. However, posterior-only surgery for Scheuermann's disease has shown a promising potential to manage this deformity, as well. Correction loss could happen post-operatively, especially when posterior-only surgery is performed in the early days. Therefore, a dispute regarding anterior release for Scheuermann's disease exists. METHODS: We performed a systematic review of studies, reporting the outcomes of anterior release and posterior fusion surgery (AP group) or posterior-only surgery (PO group) for Scheuermann's disease. Data pooling and a meta-analysis with a random-effects model were performed to evaluate the results. RESULTS: Twenty-three studies met the inclusion criteria. The pooled correction loss of Cobb angle for the AP group was 4.1(3.4, 4.8), and for the PO group, it was 3.8(3.3, 4.4). The overall effects of blood loss, surgery time, proximal junctional kyphosis (PJK), distal junctional kyphosis (DJK), self-image improvement, pain relief, and return-to-surgery were compared between the two groups. CONCLUSIONS: A systematic review of the outcomes of Scheuermann's disease demonstrated a very similar correction loss for the AP group and the PO group. A meta-regression supported that correction loss did decrease as time moved on for the PO procedure, which could be explained by the improvements to instrumentation and techniques. For other outcomes, the PO group showed advantages in blood loss, surgery time, and junctional kyphosis. Similar outcomes were observed in relation to aspects of cosmetic improvement and pain relief for the AP and PO groups. The revision rate was mildly lower in the PO group than in the AP group.

Tumor seeding is rare in prostate cancer. We reported a case of trocar-site metastasis detected at 5 months after robot-assisted laparoscopic radical prostatectomy in a prostate cancer patient with a mixed histology of small cell carcinoma and adenocarcinoma. The patient received 6 cycles of a combination of chemotherapy and immunotherapy and a maintenance regimen of androgen deprivation therapy and immunotherapy at our center. The maintenance of immunotherapy suspended at 10 months after the first dosage due to adverse effect. Three months after the end of chemotherapy, imaging evaluation showed that the tumor had achieved complete remission. Tumor relapse was not detected at 15 months after the suspension of immunotherapy.
RESUMO
A male infant, aged 6 days, was admitted to the hospital due to respiratory distress and systemic desquamative rash after birth. The infant presented with erythema and desquamative rash, respiratory failure, recurrent infections, chronic diarrhea, hypernatremic dehydration, and growth retardation. Comprehensive treatment, including anti-infection therapy, intravenous immunoglobulin administration, and skin care, resulted in improvement of the rash, but recurrent infections persisted. Second-generation sequencing revealed a homozygous mutation in the SPINK5 gene, consistent with the pathogenic variation of Netherton syndrome. The family opted for palliative care, and the infant died at the age of 2 months after discharge. This report documents a case of Netherton syndrome caused by the SPINK5 gene mutation in the neonatal period, and highlights multidisciplinary diagnosis and therapy for this condition.

RESUMO
Objective: To describe the current status and trends in the outcomes and care practices of extremely preterm infants at 22-25 weeks' gestation age from the Chinese Neonatal Network (CHNN) from 2019 to 2021. Methods: This cross-sectional study used data from the CHNN cohort of very preterm infants. All 963 extremely preterm infants with gestational age between 22-25 weeks who were admitted to neonatal intensive care units (NICU) of the CHNN from 2019 to 2021 were included. Infants admitted after 24 hours of life or transferred to non-CHNN hospitals were excluded. Perinatal care practices, survival rates, incidences of major morbidities, and NICU treatments were described according to different gestational age groups and admission years. Comparison among gestational age groups was conducted using χ2 and Kruskal-Wallis tests. Trends by year were evaluated by Cochran-Armitage and Jonckheere-Terpstra tests for trend. Results: Of the 963 extremely preterm infants enrolled, 588 extremely preterm infants (61.1%) were male. The gestational age was 25.0 (24.4, 25.6) weeks, with 29 extremely preterm infants (3.0%), 88 extremely preterm infants (9.1%), 264 extremely preterm infants (27.4%), and 582 extremely preterm infants (60.4%) at 22, 23, 24, and 25 weeks of gestation age, respectively. The birth weight was 770 (680, 840) g. From 2019 to 2021, the number of extremely preterm infants increased each year (285, 312, and 366 extremely preterm infants, respectively). Antenatal steroids and magnesium sulfate were administered to 67.7% (615/908) and 51.1% (453/886) mothers of extremely preterm infants. In the delivery room, 20.8% (200/963) and 69.5% (669/963) extremely preterm infants received noninvasive positive end-expiratory pressure support and endotracheal intubation. Delayed cord clamping and cord milking were performed in 19.0% (149/784) and 30.4% (241/794) extremely preterm infants. From 2019 to 2021, there were significant increases in the usage of antenatal steroids, antenatal magnesium sulfate, and delivery room noninvasive positive-end expiratory pressure support (all P<0.05). Overall, 349 extremely preterm infants (36.2%) did not receive complete care, 392 extremely preterm infants (40.7%) received complete care and survived to discharge, and 222 extremely preterm infants (23.1%) received complete care but died in hospital. The survival rates for extremely preterm infants at 22, 23, 24 and 25 weeks of gestation age were 10.3% (3/29), 23.9% (21/88), 33.0% (87/264) and 48.3% (281/582), respectively. From 2019 to 2021, there were no statistically significant trends in complete care, survival, and mortality rates (all P>0.05). Only 11.5% (45/392) extremely preterm infants survived without major morbidities. Moderate to severe bronchopulmonary dysplasia (67.3% (264/392)) and severe retinopathy of prematurity (61.5% (241/392)) were the most common morbidities among survivors. The incidences of severe intraventricular hemorrhage or periventricular leukomalacia, necrotizing enterocolitis, and sepsis were 15.3% (60/392), 5.9% (23/392) and 19.1% (75/392), respectively. Overall, 83.7% (328/392) survivors received invasive ventilation during hospitalization, with a duration of 22 (10, 42) days. The hospital stay for survivors was 97 (86, 116) days. Conclusions: With the increasing number of extremely preterm infants at 22-25 weeks' gestation admitted to CHNN NICU, the survival rate remained low, especially the rate of survival without major morbidities. Further quality improvement initiatives are needed to facilitate the implementation of evidence-based care practices.

RESUMO
This article reported the comprehensive management of an extremely preterm infant with severe bronchopulmonary dysplasia. The patient born at 26 +6 gestational weeks was transferred to Children's Hospital of Fudan University due to invasive mechanical ventilation dependence at 61 d after birth and was diagnosed with severe bronchopulmonary dysplasia. A comprehensive treatment plan was adopted, including appropriate fluid restriction, improving nutrition, glucocorticoid administration, using antibiotics against Ureaplasma urealyticum infection to reduce pulmonary parenchymal lesions and alleviating pulmonary hypertension. The preterm infant was successfully extubated to non-invasive ventilation and subsequently weaned to a high-flow nasal cannula. Then, the patient was discharged at 372 d after birth (correct gestational age nine months and six days). At the 3-month follow-up after discharge, the patient remained on high-flow oxygen, but with lower flow and concentration of oxygen. Moreover, the growth, development and lung images were significantly improved. Follow-up to correct gestational age one year and 11 months, the child was not on oxygen any more, but on rehabilitation due to language and motor development retardation.
RESUMO
Objective:To verify the prognostic significance of the tumor regression grade (TRG) for muscle-invasive bladder cancer (MIBC) patients undergoing radical cystectomy (RC) after neoadjuvant chemotherapy.Methods:The data of 70 MIBC patients treated with gemcitabine combined with cisplatin neoadjuvant chemotherapy and RC in Sun Yat-sen University Cancer Center between July 2016 to November 2021 were retrospectively reviewed. There were 65 males and 5 females, with an average age(59.79±10.56)years old. The patients accepted transurethral resection of bladder tumor (TURBT) specimens before neoadjuvant chemotherapy. Clinicopathological characteristics of patients were recorded and TRG was assessed. TRG evaluation criteria: TRG 1 was defined as no cancer residue, TRG 2 was defined as the proportion of residual cancer area to tumor bed area <50%, and TRG 3 was defined as the proportion of residual cancer area to the area of the tumor bed ≥ 50%. Chi-square test or Fisher's exact test were used to compare the relationship between patients' clinicopathological characteristics and TRG. The relationship between post-neoadjuvant therapy tumor and node(ypTN)stage, and survival, including overall survival(OS)and recurrence-free survival (RFS) were analyzed by Kaplan-Meier analysis. The pathologically locally descending disease was defined as (ypT < T 2 and ypN=N 0) and pathologically locally advanced disease was defined as (ypT≥T 2 and/or ypN ≥N 1). Cox regression was used for univariate and multivariate analysis of OS and RFS. Results:Chi-square test or Fisher exact test analysis showed TRG was significantly associated with ypT stage ( P < 0.001), ypN stage ( P = 0.002), lympho-vascular invasion ( P<0.001) and variant histology ( P<0.001). The OS of patients with TRG 1, TRG 2 and TRG 3 were 20.5(10.3, 31.8), 17.0(11.0, 30.8)and 15.0(11.0, 26.0) months, respectively, and the difference was significantly different( P = 0.037). The RFS of patients with TRG 1, TRG 2 and TRG 3 were 15.0(8.3, 25.5), 15.0(8.0, 27.0)and 11.0(4.5, 25.5) months, respectively, and the difference was significantly different ( P=0.029). There were significant differences between patients with pathologically locally descending disease and locally advanced disease in OS [18.5(10.3, 30.8)vs.15.0(11.0, 27.3)months, P = 0.013] and RFS [14.0(8.0, 24.0)vs. 11.5(8.0, 26.8)months, P = 0.012]. Among patients with locally advanced pathology, the OS was 19.5(11.0, 32.5)months for patients with TRG ≤2, 13.5(10.8, 26.0)months for patients with TRG 3( P=0.140). The RFS was 12.0(8.0, 31.0)months for those patients with TRG ≤2 and 11.0(6.0, 26.0)months for those patients with TRG 3( P = 0.180). Cox univariate analyses showed that patients with TRG 3 were associated with decreased OS ( HR = 6.043, 95% CI 1.170-31.213, P = 0.032) and RFS ( HR = 6.354, 95% CI 1.231-31.802, P = 0.027). Conclusions:This study showed that TRG was correlated with OS and RFS among patients. The patients who had the higher TRG had the worse prognosis. It was confirmed that TRG predicted the prognosis of patients undergoing radical cystectomy after neoadjuvant chemotherapy. Therefore, TRG assessment is recommend in pathology report for patients who had radical cystectomy after neoadjuvant chemotherapy.
RESUMO
Objective:To explore the causal relationship between body mass index (BMI) and hypothyroidism using the two-sample Mendelian randomization model.Methods:A large-scale anthropometric genome-wide association study published in the GIANT database was used to select single nucleotide polymorphisms (SNPs) which were statistically significantly associated with BMI as an instrumental variable ( P<5×10 -8, linkage disequilibrium r 2<0.1). The causal relationship between BMI and hypothyroidism was determined by the inverse variance weighted (IVW), weighted median method and the MR-Egger method, respectively. A heterogeneity test, gene pleiotropy test, and sensitivity analysis were performed to evaluate the stability and reliability of the results. Results:A total of 89 SNPs related to BMI were screened out as instrumental variables. IVW analysis suggested that for every standard deviation increase in BMI, the risk of hypothyroidism increased by 0.9% (odd ratio ( OR)=1.009, 95% confidence interval ( CI): 1.006-1.012, P<0.001). Similar results were obtained with the weighted median method ( OR=1.007, 95% CI: 1.002-1.011, P=0.003) and the MR-Egger method ( OR=1.008, 95% CI: 1.001-1.015, P=0.006). The MR-Egger analysis showed that genetic pleiotropy did not bias the results (intercept=0.000 1, P=0.776), the one-by-one exclusion method did not show that a single instrumental variable SNP had a significant impact on the results, and the difference was not statistically significant ( P>0.05). Conclusion:Mendelian randomized analysis showed a positive causal relationship between BMI and hypothyroidism.
RESUMO
Objective:To analyze the distribution of ages at the interhospital transfer of outborn very preterm infants in China and to compare their perinatal characteristics and outcomes at discharge and neonatal intensive care unit (NICU) treatment.Methods:A total of 3 405 outborn very premature infants with a gestational age of 24-31 +6 weeks who were transferred to the NICUs of the Chinese Neonatal Network (CHNN) in 2019 were included in this retrospective study. According to the age at transfer, they were divided into three groups: early transfer (≤1 d), delayed transfer (>1-7 d) and late transfer (>7 d) groups. Analysis of variance, t-test, Chi-square test (Bonferroni correction), Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare the general clinical condition, treatment, and outcomes at discharge among the three groups. Results:The median gestational age was 29.7 weeks (28.3-31.0 weeks) and the average birth weight was (1 321.0 ± 316.5) g for these 3 405 infants. There were 2 031 patients (59.6%) in the early transfer group, 406 (11.9%) in the delayed transfer group and 968 (28.4%) in the late transfer group. Infants who received continuous positive airway pressure ventilation and tracheal intubation in the delivery room accounted for 8.4% (237/2 806) and 32.9% (924/2 805), respectively. A total of 62.7% (1 569/2 504) of the mothers received antenatal glucocorticoid therapy and the ratio in the early transfer group was 68.7% (1 121/1 631), which was higher than that in the delayed transfer group [56.1% (152/271), χ2=16.78, P<0.017] and the late transfer group [49.2% (296/602), χ2=72.56, P<0.017]. The total mortality rate of very premature infants was 12.7% (431/3 405), and the mortality rates in the early, delayed and late transfer groups were 12.4% (252/2 031), 16.3% (66/406) and 11.7% (113/968), respectively ( χ2=5.72, P=0.057). The incidences of severe intraventricular hemorrhage, late-onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge were all higher in the delayed and late transfer groups than in the early transfer group, respectively. The incidences of retinopathy of prematurity, retinopathy of prematurity requiring treatment and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge in the late transfer group were significantly higher than that in the delayed transfer group (Bonferroni correction, all P<0.017). In the late transfer group, the median age of very premature infants at discharge was 66.0 d (51.0-86.0 d), and the corrected gestational age at discharge was 38.9 weeks (37.1-41.2 weeks), and both were greater than those in the early transfer [48.0 d (37.0-64.0 d), Z=260.83; 36.9 weeks (35.7-38.3 weeks), Z=294.32] and delayed transfer groups [52.0 d (41.0-64.0 d), Z=81.49; 37.4 weeks (36.1-38.7 weeks), Z=75.97] (all P<0.017). Conclusions:Many very premature infants need to be transferred to higher-level hospitals after birth. The later the very premature infants are transferred, the higher the incidence of complications will be. It is suggested that intrauterine or early postnatal transport may improve the prognosis of very premature infants.
RESUMO
Objective:The evidence-based and Delphi methods were used to construct the exercise program for hospitalized patients with diabetes foot to provide guidance for clinical practice.Methods:Evidence on exercise management of diabetic foot patients was systematically searched from BMJ Best Practice, UpToDate, Registered Nurses′ Association of Ontario and other domestic and foreign databases and professional association websites. The retrieval period was from the establishment of the database to April 2021. The quality of the included literature was independently evaluated, and the evidence of the literature meeting the quality standards was extracted and summarized to form the first draft of exercise program for inpatients with diabetic foot. After two rounds of Delphi expert letter consultation, the program items were revised, and the final draft of the exercise program for inpatients with diabetic foot suitable for clinical practice was formed.Results:The effective recovery rate of the two rounds of expert correspondence questionnaire both were15/15. The expert authority coefficient was 0.865 and 0.895 respectively. And the Kendall coordination coefficient was 0.232 and 0.291 (both P<0.01). An exercise program for inpatients with diabetic foot had been formed, including 5 modules(exercise evaluation, exercise prescription, exercise monitoring, post-exercise evaluation and exercise management), 12 items and 40 operational items. Conclusions:The exercise program for inpatients with diabetic foot constructed in this study is scientific and clinically applicable, which provide scientific guidance for clinical medical staff to carry out exercise practice.
RESUMO
Objective: To investigate the clinical features, diagnosis, prognosis of malignant mesothelioma of the tunica vaginalis testis (MMTVT). Methods: The clinicopathological data of 7 patients with MMTVT who treated at Sun Yat-sen University Cancer Center between January 2010 and October 2022 were retrospectively reviewed. Cases were first diagnosed at (M (IQR)) 49 (23) years old (range: 27 to 64 years old). The main clinical manifestations were scrotal enlargement (7 cases) and hydrocele (2 cases). Results: Three patients underwent radical orchiectomy as initial treatment, 2 cases underwent hydrocelectomy due to diagnosis of hydrocele, followed by radical orchiectomy at Sun Yat-sen University Cancer Center, and 2 cases underwent transscrotal orchiectomy. Common tumor markers of testicular cancer were not significantly elevated in MMTVT. The expression of tumor PD-L1 was positive in 2 out of the 3 cases. One patient received adjuvant chemotherapy and 2 patients received first-line chemotherapy after tumor recurrence. Chemotherapy regimens used include cisplatin+pemetrexed. Up to October 2022, 3 cases relapsed, of which 2 cases died. The median overall survival was 35 months (range: 4 to 87 months) and the median progression-free survival was 6 months (range: 2 to 87 months). Conclusions: MMTVT at early stage should be treated with early radical orchiectomy and followed up closely after surgery. The cisplatin+pemetrexed regimen is a common option for the treatment of metastatic MMTVT, while whether immune checkpoint inhibitors could serve as a second-line treatment option deserves further research.
RESUMO
The female infant in this case study was admitted to the hospital 4 hours after birth due to preterm birth and respiratory distress. On the third day after birth, peripherally inserted central venous catheter (PICC) catheterization was performed. On day 42, thrombus was found at the entrance of the right atrium from the inferior vena cava during a cardiac ultrasound, and it was considered to be related to PICC placement. Low-molecular-weight heparin and urokinase were given. After two weeks of treatment, ultrasonic monitoring showed thrombus shrinkage. No bleeding or pulmonary embolism occurred during the treatment. The patient discharged after improvement. This article mainly introduces a multidisciplinary team approach to diagnosis and treatment of PICC-related thrombosis in neonates.

BACKGROUND@#Significant brain volume deviation is an essential phenotype in children with neurodevelopmental delay (NDD), but its genetic basis has not been fully characterized. This study attempted to analyze the genetic factors associated with significant whole-brain deviation volume (WBDV).@*METHODS@#We established a reference curve based on 4222 subjects ranging in age from the first postnatal day to 18 years. We recruited only NDD patients without acquired etiologies or positive genetic results. Cranial magnetic resonance imaging (MRI) and clinical exome sequencing (2742 genes) data were acquired. A genetic burden test was performed, and the results were compared between patients with and without significant WBDV. Literature review analyses and BrainSpan analysis based on the human brain developmental transcriptome were performed to detect the potential role of genetic risk factors in human brain development.@*RESULTS@#We recruited a total of 253 NDD patients. Among them, 26 had significantly decreased WBDV (<-2 standard deviations [SDs]), and 14 had significantly increased WBDV (>+2 SDs). NDD patients with significant WBDV had higher rates of motor development delay (49.8% [106/213] vs . 75.0% [30/40], P = 0.003) than patients without significant WBDV. Genetic burden analyses found 30 genes with an increased allele frequency of rare variants in patients with significant WBDV. Analyses of the literature further demonstrated that these genes were not randomly identified: burden genes were more related to the brain development than background genes ( P = 1.656e -9 ). In seven human brain regions related to motor development, we observed burden genes had higher expression before 37-week gestational age than postnatal stages. Functional analyses found that burden genes were enriched in embryonic brain development, with positive regulation of synaptic growth at the neuromuscular junction, positive regulation of deoxyribonucleic acid templated transcription, and response to hormone, and these genes were shown to be expressed in neural progenitors. Based on single cell sequencing analyses, we found TUBB2B gene had elevated expression levels in neural progenitor cells, interneuron, and excitatory neuron and SOX15 had high expression in interneuron and excitatory neuron.@*CONCLUSION@#Idiopathic NDD patients with significant brain volume changes detected by MRI had an increased prevalence of motor development delay, which could be explained by the genetic differences characterized herein.

BACKGROUND@#Antenatal corticosteroids (ACS) can significantly improve the outcomes of preterm infants. This study aimed to describe the ACS use rates among preterm infants admitted to Chinese neonatal intensive care units (NICU) and to explore perinatal factors associated with ACS use, using the largest contemporary cohort of very preterm infants in China.@*METHODS@#This cross-sectional study enrolled all infants born at 24 +0 to 31 +6 weeks and admitted to 57 NICUs of the Chinese Neonatal Network from January 1st, 2019 to December 30th, 2019. The ACS administration was defined as at least one dose of dexamethasone and betamethasone given before delivery. Multiple logistic regressions were applied to determine the association between perinatal factors and ACS usage.@*RESULTS@#A total of 7828 infants were enrolled, among which 6103 (78.0%) infants received ACS. ACS use rates increased with increasing gestational age (GA), from 177/259 (68.3%) at 24 to 25 weeks' gestation to 3120/3960 (78.8%) at 30 to 31 weeks' gestation. Among infants exposed to ACS, 2999 of 6103 (49.1%) infants received a single complete course, and 33.4% (2039/6103) infants received a partial course. ACS use rates varied from 30.2% to 100% among different hospitals. Multivariate regression showed that increasing GA, born in hospital (inborn), increasing maternal age, maternal hypertension and premature rupture of membranes were associated with higher likelihood to receive ACS.@*CONCLUSIONS@#The use rate of ACS remained low for infants at 24 to 31 weeks' gestation admitted to Chinese NICUs, with fewer infants receiving a complete course. The use rates varied significantly among different hospitals. Efforts are urgently needed to propose improvement measures and thus improve the usage of ACS.

The male neonate in this case study was admitted to the hospital at 15 hours of age due to respiratory distress for 15 hours and poor response for 3 hours after resuscitation from asphyxia. The neonate was highly unresponsive, with central respiratory failure and seizures. Serum ammonia was elevated (>1 000 μmol/L). Blood tandem mass spectrometry revealed a significant decrease in citrulline. Rapid familial whole genome sequencing revealed OTC gene mutations inherited from the mother. Continuous hemodialysis filtration and other treatments were given. Neurological assessment was performed by cranial magnetic resonance imaging and electroencephalogram. The neonate was diagnosed with ornithine transcarbamylase deficiency combined with brain injury. He died at 6 days of age after withdrawing care. This article focuses on the differential diagnosis of neonatal hyperammonemia and introduces the multidisciplinary management of inborn error of metabolism.

This report presents a case of a male infant, aged 32 days, who was admitted to the hospital due to 2 days of bloody stools and 1 day of fever. Upon admission, venous blood samples were collected, which appeared pink. Blood biochemistry tests revealed elevated levels of triglycerides and total cholesterol. The familial whole genome sequencing revealed a compound heterozygous variation in the LPL gene, with one variation inherited from the father and the other from the mother. The patient was diagnosed with lipoprotein lipase deficiency-related hyperlipoproteinemia. Acute symptoms including bloody stools, fever, and bloody ascites led to the consideration of acute pancreatitis, and the treatment involved fasting, plasma exchange, and whole blood exchange. Following the definitive diagnosis based on the genetic results, the patient was given a low-fat diet and received treatment with fat-soluble vitamins and trace elements, as well as adjustments to the feeding plan. After a 4-week hospitalization, the patient's condition improved and he was discharged. Follow-up showed a decrease in triglycerides and total cholesterol levels. At the age of 1 year, the patient's growth and psychomotor development were normal. This article emphasizes the multidisciplinary diagnosis and treatment of familial hyperlipoproteinemia presenting with symptoms suggestive of acute pancreatitis, including bloody ascites, in the neonatal period.

RESUMO
Objective: To comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ2 test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (ORadjust=1.01, 95%CI 1.01-1.02, P<0.001; ORadjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (ORadjust=2.64, 95%CI 1.60-4.35, P<0.001; ORadjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (ORadjust=1.94, 95%CI 1.50-2.51, P<0.001; ORadjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (ORadjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (ORadjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (ORadjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.
