The patient, a 20-day-old male, was admitted due to respiratory distress that had persisted for 20 days after birth. The main clinical manifestations included gradually worsening respiratory distress and edema. The patient received treatment including mechanical ventilation and diuretics. Echocardiography indicated cardiomegaly, pulmonary hypertension, and heart failure. A comprehensive systemic examination revealed a significant blowing vascular murmur upon auscultation over the anterior fontanelle and bilateral temporal regions. Further imaging studies including cranial magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography showed marked dilation of the superior sagittal sinus, transverse sinus, and sigmoid sinus, leading to a definitive diagnosis of dural arteriovenous fistula. After a multidisciplinary consultation, the patient underwent cerebral angiography and partial embolization of the left parietal arteriovenous fistula. Postoperatively, the patient was treated with positive inotropes, diuretics, and fluid restriction. Ultimately, the patient was weaned off the ventilator and discharged in improved condition. This article reports a case of neonatal dural arteriovenous fistula presenting with respiratory distress and discusses the multidisciplinary approach to managing this condition, which aids in early disease recognition and guides clinical decision-making.

OBJECTIVES: To investigate the application value of targeted next-generation sequencing (tNGS) in the etiological diagnosis of moderate to severe respiratory distress syndrome (RDS) in neonates. METHODS: A prospective randomized controlled trial was conducted, enrolling 81 term and late-preterm neonates with moderate to severe RDS admitted to Fujian Children's Hospital between December 2023 and December 2024. Patients were randomly assigned to the conventional microbiological test (CMT) group (n=42) or the tNGS group (n=39). For routine pathogen detection, bronchoalveolar lavage fluid was obtained via bronchoscopy, and lower respiratory tract specimens were collected via the endotracheal tube; all specimens underwent culture, and some specimens additionally underwent polymerase chain reaction or antigen testing. In the tNGS group, tNGS was performed in addition to routine pathogen detection on the same specimen types. The detection rate of pathogens, the detection rate of co-infections, and the duration of antibiotic use were compared between the two groups. RESULTS: The pathogen detection rate in the tNGS group (18/39, 46%) was significantly higher than that in the CMT group (8/42, 19%) (P=0.009). The co-infection detection rate was 13% (5/39) in the tNGS group, while no co-infections were identified in the CMT group (P=0.024). Regarding treatment, the duration of antibiotic use in the tNGS group was shorter than that in the CMT group [(12±4) days vs (15±5) days, P=0.003]. CONCLUSIONS tNGS significantly improves the pathogen detection rate in neonates with moderate to severe RDS and offers advantages in the rapid identification of co-infections and reduction of antibiotic treatment duration, suggesting it has clinical utility and potential for wider adoption.

OBJECTIVE: To study the association of different stages of histological chorioamnionitis (HCA) with the incidence rate and severity of respiratory distress syndrome (RDS) in preterm infants. METHODS: Related data were collected from the infants and their mothers who were treated in the Neonatal Intensive Care Unit of Qingdao Women and Children's Hospital, Qingdao University, from January 2018 to June 2020. According to the presence or absence of HCA and its stage, the infants were divided into four groups: control ( RESULTS: Compared with the control and late-stage HCA groups, the early-stage HCA group had a significantly lower incidence rate of placental abruption and a significantly higher rate of prenatal use of antibiotics ( CONCLUSIONS Early-, middle-, and late-stage HCA can reduce the incidence rate of RDS in preterm infants. HCA stage may not be correlated with RDS severity in preterm infants, which needs to be verified by further research.

OBJECTIVES: To construct risk prediction models for bronchopulmonary dysplasia (BPD) in preterm infants on postnatal days 3, 7, and 14. METHODS: A retrospective analysis was performed on the medical data of 414 preterm infants, with a gestational age of <32 weeks and a birth weight (BW) of <1 500 g, who were admitted to the neonatal intensive care unit from July 2019 to April 2021. According to the diagnostic criteria for BPD revised in 2018, they were divided into a BPD group with 98 infants and a non-BPD group with 316 infants. The two groups were compared in terms of general status, laboratory examination results, treatment, and complications. The logistic regression model was used to identify the variables associated with BPD. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of models. RESULTS: The logistic regression analysis showed that BW, asphyxia, grade III-IV respiratory distress syndrome (RDS), acute chorioamnionitis, interstitial pneumonia, fraction of inspired oxygen (FiO CONCLUSIONS BW, asphyxia, grade III-IV RDS, acute chorioamnionitis, interstitial pneumonia, FiO

OBJECTIVETo study the effect of pregnancy-induced hypertension syndrome (PIH) on complications in very low birth weight (VLBW) preterm infants.

METHODSThe VLBW preterm infants were enrolled as research subjects, and according to the presence or absence of PIH in their mothers, they were divided into PIH group and non- PIH group. The incidence of major complications and length of hospital stay were compared between the two groups.

RESULTSThere were no significant differences between the two groups in gestational age, birth weight, sex, incidence rate of maternal diabetes, and use of antepartum hormone. The PIH group had a significantly higher rate of birth of small-for-gestational-age infants than the non-PIH group. The PIH group had a significantly lower incidence rate of bronchopulmonary dysplasia (BPD) than the non-PIH group, while there were no significant differences between the two groups in the incidence rates of apnea of prematurity, necrotizing enterocolitis, retinopathy of prematurity, and intraventricular hemorrhage-periventricular leukomalacia, and the length of hospital stay. There was no significant difference in the incidence rate of neonatal respiratory distress syndrome between the two groups, but the PIH group had a significantly lower proportion of infants who used pulmonary surfactant than the non-PIH group.

CONCLUSIONSPIH can alleviate respiratory complications and reduce the use of pulmonary surfactant and the incidence rate of BPD in preterm infants.

OBJECTIVETo explore the high-risk factors and analyze the clinical characteristics of massive pulmonary hemorrhage (MPH) in infants with extremely low birth weight (ELBW).

METHODSTwo hundred and eleven ELBW infants were included in this study. Thirty-five ELBW infants who were diagnosed with MPH were labelled as the MPH group, and 176 ELBW infants without pulmonary hemorrhage were labelled as the control group. The differences in clinical characteristics, mortality rate, and incidence of complications between the two groups were analysed. The high-risk factors for MPH were identified by multiple logistic regression analysis.

RESULTSThe MPH group had significantly lower gestational age, birth weight, and 5-minute Apgar score than the control group (P<0.05). The MPH group had significantly higher rates of neonatal respiratory distress syndrome, patent ductus arteriosus (PDA), early-onset sepsis (EOS), intracranial hemorrhage, pulmonary surfactant utilization, and death compared with the control group (P<0.01). The multiple logistic regression analysis showed that 5-minute Apgar score was a protective factor for MPH (OR=0.666, P<0.05), and that PDA and EOS were risk factors for MPH (OR=3.717, 3.276 respectively; P<0.01). In the infants who were discharged normally, the MPH group had a longer duration of auxiliary ventilation and a higher incidence rate of ventilator-associated pneumonia (VAP) compared with the control group (P<0.05).

CONCLUSIONSA higher 5-minute Apgar score is associated a decreased risk for MPH, and the prensence of PDA or EOS is associated an increased risk for MPH in ELBW infants. ELBW infants with MPH have a prolonged mechanical ventilation, a higher mortality, and higher incidence rates of VAP and intracranial hemorrhage compared with those without pulmonary hemorrhage.

OBJECTIVETo investigate the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels at birth and respiratory distress syndrome (RDS) in preterm infants.

METHODSThis retrospective study recruited preterm infants with gestational age of below 34 weeks who were born between January 2014 and December 2016. These preterm infants were divided into two groups: RDS (n=72) and control (n=40). Clinical data of the two groups were collected, including gestational age, birth weight, gender, delivery mode, Apgar scores at 1 minute and 5 minutes, incidence of maternal gestational diabetes mellitus, and use of prenatal steroid hormone. Peripheral blood samples were collected and 25(OH)D levels were measured by chemiluminescence immunoassay. The association between serum 25(OH)D levels at birth and RDS was analyzed by multivariate logistic regression.

RESULTSApgar scores at 1 minute and 5 minutes and serum 25(OH)D levels in the RDS group were significantly lower than those in the control group (P<0.05), while the rates of neonatal asphyxia and vitamin D deficiency were significantly higher than those in the control group (P<0.05). Multivariate logistic regression analysis showed that neonatal asphyxia (OR=2.633, 95%CI: 1.139-6.085) and vitamin D deficiency (OR=4.064, 95%CI: 1.625-10.165) were risk factors for RDS in preterm infants.

CONCLUSIONSVitamin D deficiency might be associated with increased risk of RDS in preterm infants. Reasonable vitamin D supplementation during pregnancy might reduce the incidence of RDS in preterm infants.

OBJECTIVETo study the efficacy of early caffeine treatment in preterm infants with respiratory distress syndrome (RDS).

METHODSA prospective controlled clinical trial was performed. A total of 59 preterm infants with RDS were enrolled and divided into a caffeine group (30 infants) and a control group (29 infants). Caffeine was administered in the caffeine group and control group at the same dosage at 12-24 hours after birth and before extubation respectively. The respirator parameters and the incidence rates of ventilator-associated pneumonia (VAP) and apnea were compared between the two groups.

RESULTSCompared with the control group, the caffeine group had significantly lower peak inspiratory pressure, peak fraction of inspired oxygen, and incidence rate of VAP (p<0.05), as well as significantly shorter intubation time, NCPAP time, and total duration of oxygen supply (p<0.05). In addition, the caffeine group had a significantly longer time to first onset of apnea after extubation (p<0.05) and significantly fewer times of onset of apnea 1-2 days after extubation (p<0.01), as compared with the control group.

CONCLUSIONSEarly caffeine treatment can reduce the need for assisted ventilation in preterm infants with RDS, help with early extubation and ventilator weaning, reduce the oxygen time in the late stage, reduce the incidence of VAP, and prevent the development of apnea after extubation.

OBJECTIVETo study clinical features of respiratory distress syndrome (RDS) in neonates of different gestational ages (GA).

METHODSAccording to GA, 133 neonates with RDS were classified into GA <34 weeks group (n=66), GA 34-36 weeks group (late preterm neonates; n=31), and GA ≥37 weeks group (full-term neonates; n=36). The mothers' medical history during pregnancy and the condition of the neonates at birth were retrospectively analyzed, and the clinical data were compared between groups.

RESULTSPrenatal corticosteroids supplementation in the GA <34 weeks group was more common than that in the GA 34-36 weeks group (P<0.05). Compared with the GA ≥37 weeks group and the GA 34-36 weeks group, the GA <34 weeks group showed a significantly lower rate of primary diseases, a significantly later time of the development of dyspnea (P<0.05), and a higher rate of intraventricular hemorrhage (P<0.05). Serum albumin levels in the GA <34 weeks group were significantly lower than in the GA ≥37 weeks group (P<0.05). The GA ≥37 weeks group and the GA 34-36 weeks group showed a significantly higher reuse rate of pulmonary surfactant (P<0.05). Use of high-frequency oscillatory ventilation was more common in the GA ≥37 weeks group compared with the GA <34 weeks group (P<0.05).

CONCLUSIONSThe clinical features of RDS are different across neonates of different GA, suggesting that the pathogenesis of RDS may be different in neonates of different GA.

OBJECTIVETo study the risk factors for the development of acute respiratory distress syndrome (ARDS) in children with measles.

METHODSThe clinical data of 55 children with measles were retrospectively studied. Of the 55 children, 11 were complicated by ARDS. The risk factors for the development of ARDS were investigated by univariate analysis and multivariate non-conditional logistic regression analysis.

RESULTSThe univariate analysis showed that there were significant differences in the oxygen inhalation mode (nasal catheter/mask), the rate of sepsis, blood C-reactive protein (CRP) levels and lymphocyte counts at admission between the ARDS and non-ARDS groups (P<0.05). The presence of sepsis and higher blood CRP levels were identified as the major risk factors for the development of ARDS by the multivariate logistic regression analysis (OR=116.444, 1.050 respectively; P<0.05).

CONCLUSIONSThe children with measles who have sepsis and higher blood CRP levels are at risk of ARDS.
