Expert consensus on standard clinical management of neonatal hypoglycemia in China (2021) Hot!
There are many high-risk factors for neonatal hypoglycemia, and persistent severe hypoglycemia can lead to irreversible neurological damage and bring a great burden to family and society. Early standardized prevention and clinical management can effectively reduce the incidence rate of neonatal hypoglycemia and brain injury induced by hypoglycemia; however at present, there is still a lack of unified clinical management guidelines for neonatal hypoglycemia in China, and different medical institutions follow different clinical guidelines developed by other countries for the management of neonatal hypoglycemia. In order to further standardize the clinical management of neonatal hypoglycemia, this consensus is developed by the Group of Neonatology, Pediatric Society, Chinese Medical Association. This consensus provides 21 recommendations to address related clinical issues in the prevention, monitoring, and management of hypoglycemia in neonates with a gestational age of ≥35 weeks.

Expert consensus on the clinical practice of neonatal brain magnetic resonance imaging
In recent years, magnetic resonance imaging (MRI) has been widely used in evaluating neonatal brain development, diagnosing neonatal brain injury, and predicting neurodevelopmental prognosis. Based on current research evidence and clinical experience in China and overseas, the Neonatologist Society of Chinese Medical Doctor Association has developed a consensus on the indications and standardized clinical process of neonatal brain MRI. The consensus has the following main points. (1) Brain MRI should be performed for neonates suspected of hypoxic-ischemic encephalopathy, intracranial infection, stroke and unexplained convulsions; brain MRI is not considered a routine in the management of preterm infants, but it should be performed for further evaluation when cranial ultrasound finds evidence of brain injury; as for extremely preterm or extremely low birth weight infants without abnormal ultrasound findings, it is recommended that they should undergo MRI examination at term equivalent age once. (2) Neonates should undergo MRI examination in a non-sedated state if possible. (3) During MRI examination, vital signs should be closely monitored to ensure safety; the necessity of MRI examination should be strictly evaluated for critically ill neonates, and magnetic resonance compatible incubator and ventilator can be used. (4) At present, 1.5 T or 3.0 T equipment can be used for neonatal brain MRI examination, and the special coil for the neonatal head should be used to improve signal-to-noise ratio; routine neonatal brain MRI sequences should at least include axial T1 weighted image (T1WI), axial T2 weighted imaging (T2WI), diffusion-weighted imaging, and sagittal T1WI or T2WI. (5) It is recommended to use a structured and graded reporting system, and reports by at least two reviewers and multi-center collaboration are recommended to increase the reliability of the report.

Value of bedside echocardiography in predicting persistent patency of the ductus arteriosus during the early postnatal period in very low birth weight infants
Objective To study the value of bedside echocardiography in predicting persistent patency of the ductus arteriosus during the early postnatal period in very low birth weight (VLBW) infants. Methods A retrospective analysis was performed for 51 VLBW infants who were admitted from March 2020 to June 2021, with an age of ≤3 days and a length of hospital stay of ≥14 days. According to the diameter of patent ductus arteriosus (PDA) on days 14 and 28 after birth, the infants were divided into three groups: large PDA group (PDA diameter ≥2 mm), small PDA group (PDA diameter <2 mm), and PDA closure group (PDA diameter =0 mm). The echocardiographic parameters measured at 72 hours after birth were compared among the three groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of the echocardiographic parameters in predicting persistent patency of the ductus arteriosus (PDA≥2 mm) at the ages of 14 and 28 days. Results On day 14 after birth, there were 17 infants in the large PDA group, 11 in the small PDA group, and 23 in the PDA closure group. On day 28 after birth, there were 14 infants in the large PDA group, 9 in the small PDA group, and 26 in the PDA closure group. There were significant differences in gestational age, birth weight, rate of pulmonary surfactant use, and incidence rate of hypotension among the three groups (P<0.05). PDA diameter, end-diastolic velocity of the left pulmonary artery, left ventricular output, and left ventricular output/superior vena cava flow ratio measured at 72 hours after birth were associated with persistent patency of the ductus arteriosus at the ages of 14 and 28 days (P<0.05), and the ratio of the left atrium to aorta diameter was associated with persistent patency of the ductus arteriosus at the age of 28 days (P<0.05). The ROC curve analysis showed that the area under the curve that the PDA diameter measured at 72 hours after birth predicting the persistent patency of the ductus arteriosus at the ages of 14 and 28 days was the largest (0.841 and 0.927 respectively), followed by end-diastolic velocity of the left pulmonary artery, with the area under the curve of 0.793 and 0.833 respectively. Conclusions The indicators obtained by beside echocardiography at 72 hours after birth, especially PDA diameter and end-diastolic velocity of the left pulmonary artery, can predict persistent patency of the ductus arteriosus at the ages of 14 and 28 days in VLBW infants, which provides a basis for the implementation of early targeted treatment strategy for PDA.

Clinical treatment outcomes and their changes in extremely preterm twins: a multicenter retrospective study in Guangdong Province, China
Objective To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. Methods A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. Results Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). Conclusions There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Risk factors for necrotizing enterocolitis and establishment of prediction model of necrotizing enterocolitis in preterm infants
Objective To investigate the risk factors for necrotizing enterocolitis (NEC) in preterm infants, and to establish a scoring model that can predict the development and guide the prevention of NEC. Methods A retrospective analysis was performed on the medical data of preterm infants who were admitted to the Department of Neonatology,Bethune First Hospital of Jilin University, from January 2011 to December 2020. These infants were divided into two groups: NEC (298 infants with Bell II stage or above) and non-NEC (300 infants). Univariate and multivariate analyses were performed to identify the factors influencing the development of NEC. A nomogram for predicting the risk of NEC was established based on the factors. The receiver operator characteristic (ROC) curve and the index of concordance (C-index) were used to evaluate the predictive performance of the nomogram. Results The multivariate logistic regression analysis showed that grade ≥2 intracranial hemorrhage, peripherally inserted central catheterization, breast milk fortifier, transfusion of red cell suspension, hematocrit >49.65%, mean corpuscular volume >114.35 fL, and mean platelet volume >10.95 fL were independent risk factors for NEC (P<0.05), while the use of pulmonary surfactant, the use of probiotics, and the platelet distribution width >11.8 fL were protective factors against NEC (P<0.05). The nomogram showed good accuracy in predicting the risk of NEC, with a bootstrap-corrected C-index of 0.844. The nomogram had an optimal cutoff value of 171.02 in predicting the presence or absence of NEC, with a sensitivity of 74.7% and a specificity of 80.5%. Conclusions The prediction nomogram for the risk of NEC has a certain clinical value in early prediction, targeted prevention, and early intervention of NEC.

Effect of intrapartum antibiotic prophylaxis of group B streptococcus infection on the incidence and bacteriological profile of early-onset neonatal sepsis
Objective To study the effect of intrapartum antibiotic prophylaxis (IAP) of group B streptococcus (GBS) infection on the incidence and bacteriological profile of early-onset neonatal sepsis (EONS). Methods A retrospective analysis was performed on the medical data of 494 pregnant women with positive GBS screening results and 526 neonates born by these women. According to whether the pregnant woman received IAP, the neonates were divided into two groups: IAP (n=304) and control (n=222). The two groups were compared in terms of clinical indices, incidence rate of EONS, and distribution of pathogenic bacteria in blood culture. Results Compared with the control group, the IAP group had a significantly lower proportion of children with abnormal clinical manifestations (P<0.001) and a significantly lower incidence rate of EONS (P=0.022). In the IAP group, Escherichia coli (2.3%) was the most common type of pathogenic bacteria in blood culture of the neonates with EONS, while GBS (3.2%) was the most common type of pathogenic bacteria in the control group. The IAP group had a significantly higher detection rate of ampicillin-resistant Escherichia coli than the control group (P=0.029). Conclusions Although IAP can significantly reduce the incidence rate of EONS in neonates born to pregnant women with positive GBS screening results, the infection rate of ampicillin-resistant Escherichia coli may increase after IAP treatment. Therefore, it is needed to enhance the monitoring of blood culture results of neonates with EONS and timely adjust treatment plan according to drug susceptibility test results.

Association of asymmetric dimethylarginine with the pathological process of persistent pulmonary hypertension of the newborn
Objective To study the change in asymmetric dimethylarginine (ADMA) in the circulation system of full-term infants with persistent pulmonary hypertension of the newborn (PPHN) and its association with treatment response, as well as the possibility of ADMA as a therapeutic target and a marker for treatment response. Methods A prospective study was performed. A total of 30 full-term neonates who were diagnosed with PPHN within 3 days after birth were enrolled as the PPHN group, and the neonates without PPHN, matched for gestational age and age, who were treated or observed in the department of neonatology were enrolled as the control group. Serum samples were collected on days 1, 7, and 14 of treatment. The high-performance liquid chromatography-tandem mass spectrometry was used to measure the serum concentrations of L-arginine, ADMA, and its isomer symmetric dimethylarginine (SDMA). Results For the neonates in the control group, the serum concentrations of ADMA and L-arginine continuously increased and the serum concentration of SDMA continuously decreased within the first 14 days of treatment. On days 1 and 14, there was no significant difference in the serum concentration of ADMA between the control and PPHN groups (P>0.05). On day 7, the PPHN group had a significantly higher serum concentration of ADMA than the control group (P<0.05), while there were no significant differences in serum concentrations of SDMA or L-arginine (P>0.05). Moreover, after 7 days of treatment, the PPHN neonates with a systolic pulmonary arterial pressure (sPAP) of >35 mmHg had a significantly higher serum concentration of ADMA than those with an sPAP of ≤35 mm Hg. Conclusions There are continuous increases in the ADMA concentration and the ADMA/SDMA ratio in the circulation system of full-term infants within the first 2 weeks after birth, and this process is accelerated by the pathological process of PPHN, suggesting that ADMA may be involved in the pathologic process of PPHN. A high level of ADMA is associated with the resistance to PPHN treatment, suggesting that inhibition of ADMA might be a potential target of drug intervention to improve the treatment response of PPHN.

Effect of hypertensive disorders of pregnancy on peripheral venous blood cell count in preterm infants with a gestational age of 28-34 weeks
Objective To study the effect of hypertensive disorders of pregnancy on peripheral venous blood cell count in preterm infants with a gestational age of 28-34 weeks. Methods A total of 227 preterm infants with a gestational age of 28-34 weeks who were admitted to the Department of Pediatrics, the First Hospital Affiliated to Kunming Medical University, from January to December 2020, and whose mothers had hypertensive disorders of pregnancy were enrolled as the study group. A total of 227 preterm infants with a gestational age of 28-34 weeks who were admitted during the same period and whose mothers did not have hypertensive disorders of pregnancy were enrolled as the control group. According to maternal blood pressure during pregnancy, the study group was divided into three subgroups: gestational hypertension (n=75), mild preeclampsia (n=81), and severe preeclampsia (n=71). According to the birth weight of the preterm infants, the study group was divided into two subgroups: small for gestational age (SGA) (n=113) and appropriate for gestational age (AGA) (n=114). Peripheral blood cell count on day 1 after birth was compared between the study and control groups, as well as between the subgroups of the study group. Results Compared with the control group, the study group had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count (P<0.05) and significantly higher incidence rates of leucopenia and neutropenia (P<0.05). The subgroup analysis showed that the mild preeclampsia and severe preeclampsia subgroups had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count than the gestational hypertension subgroup (P<0.05), and that the SGA subgroup had significantly lower white blood cell count, absolute neutrophil count, and blood platelet count than the AGA subgroup (P<0.05). Conclusions Hypertensive disorders of pregnancy can affect the peripheral venous blood cell count of preterm infants, which is more significant in infants with maternal preeclampsia and SGA infants.

A retrospective cohort study of tracheal intubation for meconium suction in nonvigorous neonates
Objective To study the feasibility of tracheal intubation for meconium suction immediately after birth of nonvigorous neonates born through meconium-stained amniotic fluid (MSAF). Methods A retrospective cohort study was performed on nonvigorous neonates born through MSAF who were admitted to the Department of Neonatology, Zhecheng People's Hospital. The neonates without meconium suction who were admitted from July 1, 2017 to June 30, 2018 were enrolled as the control group. The neonates who underwent meconium suction from July 1, 2018 to June 30, 2019 were enrolled as the suction group. The two groups were compared in terms of the mortality rate and the incidence rates of neonatal meconium aspiration syndrome (MAS), persistent pulmonary hypertension of the newborn, pneumothorax, and pulmonary hemorrhage. Results There were 80 neonates in the control group and 71 in the suction group. There were no significant differences between the two groups in the incidence rates of MAS (11% vs 7%), persistent pulmonary hypertension of the newborn (5% vs 4%), pneumothorax (3% vs 1%), and death (0% vs 1%). Compared with the control group, the suction group had a significantly lower proportion of neonates requiring oxygen inhalation (16% vs 33%, P<0.05), noninvasive respiratory support (25% vs 41%, P<0.05) or mechanical ventilation (10% vs 23%, P<0.05) and significantly shorter duration of noninvasive ventilation [(58±24) hours vs (83±41) hours, P<0.05] and length of hospital stay [6(4, 8) days vs 7(5, 10) days, P<0.05]. Conclusions Although tracheal intubation for meconium suction immediately after birth may shorten the duration of respiratory support for mild respiratory problems, it cannot reduce the incidence rate of MAS, mortality rate, or the incidence rate of serious complications in nonvigorous infants born through MSAF.

Expression and role of anti-oxidative damage factors in the placenta of preterm infants with premature rupture of membranes
Objective To study the association of the anti-oxidative damage factors nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and NAD(P)H:quinone oxidoreductase-1 (NQO1) with preterm premature rupture of membranes (PPROM). Methods A prospective study was conducted. The neonates who were hospitalized in Yanbian Hospital from 2019 to 2020 were enrolled as subjects, among whom there were 30 infants with PPROM, 32 infants with term premature rupture of membranes (TPROM), and 35 full-term infants without premature rupture of membranes (PROM). Hematoxylin and eosin staining was used to observe the inflammatory changes of placental tissue. Immunohistochemical staining was used to measure the expression of Nrf2, HO-1, and NQO1 in placental tissue. Western blot was used to measure the protein expression levels of Nrf2, HO-1, and NQO1 in placental tissue. Results Compared with the PPROM group, the TPROM group and the non-PROM full-term group had significantly higher positive expression rates and relative protein expression levels of Nrf2, HO-1, and NQO1 in placental tissue (P<0.05). There were no significant differences in the positive expression rates and relative protein expression levels of Nrf2, HO-1, and NQO1 in placental tissue between the TPROM and non-PROM full-term groups (P>0.05). Conclusions The low expression levels of Nrf2, HO-1, and NQO1 in placental tissue may be associated with PPROM, suggesting that anti-oxidative damage is one of the directions to prevent PPROM.

Value of bedside echocardiography in predicting persistent patency of the ductus arteriosus during the early postnatal period in very low birth weight infants

Objective To study the value of bedside echocardiography in predicting persistent patency of the ductus arteriosus during the early postnatal period in very low birth weight (VLBW) infants. Methods A retrospective analysis was performed for 51 VLBW infants who were admitted from March 2020 to June 2021, with an age of ≤3 days and a length of hospital stay of ≥14 days. According to the diameter of patent ductus arteriosus (PDA) on days 14 and 28 after birth, the infants were divided into three groups: large PDA group (PDA diameter ≥2 mm), small PDA group (PDA diameter <2 mm), and PDA closure group (PDA diameter =0 mm). The echocardiographic parameters measured at 72 hours after birth were compared among the three groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of the echocardiographic parameters in predicting persistent patency of the ductus arteriosus (PDA≥2 mm) at the ages of 14 and 28 days. Results On day 14 after birth, there were 17 infants in the large PDA group, 11 in the small PDA group, and 23 in the PDA closure group. On day 28 after birth, there were 14 infants in the large PDA group, 9 in the small PDA group, and 26 in the PDA closure group. There were significant differences in gestational age, birth weight, rate of pulmonary surfactant use, and incidence rate of hypotension among the three groups (P<0.05). PDA diameter, end-diastolic velocity of the left pulmonary artery, left ventricular output, and left ventricular output/superior vena cava flow ratio measured at 72 hours after birth were associated with persistent patency of the ductus arteriosus at the ages of 14 and 28 days (P<0.05), and the ratio of the left atrium to aorta diameter was associated with persistent patency of the ductus arteriosus at the age of 28 days (P<0.05). The ROC curve analysis showed that the area under the curve that the PDA diameter measured at 72 hours after birth predicting the persistent patency of the ductus arteriosus at the ages of 14 and 28 days was the largest (0.841 and 0.927 respectively), followed by end-diastolic velocity of the left pulmonary artery, with the area under the curve of 0.793 and 0.833 respectively. Conclusions The indicators obtained by beside echocardiography at 72 hours after birth, especially PDA diameter and end-diastolic velocity of the left pulmonary artery, can predict persistent patency of the ductus arteriosus at the ages of 14 and 28 days in VLBW infants, which provides a basis for the implementation of early targeted treatment strategy for PDA.

Efficacy and safety of intratracheal administration of budesonide combined with pulmonary surfactant in preventing bronchopulmonary dysplasia: a prospective randomized controlled trial
Objective To study the efficacy and safety of early intratracheal administration of budesonide combined with pulmonary surfactant (PS) in preventing bronchopulmonary dysplasia (BPD). Methods A prospective randomized controlled trial was designed. A total of 122 infants with a high risk of BPD who were admitted to the neonatal intensive care unit of the Third Affiliated Hospital of Zhengzhou University from January to July 2021 were enrolled. The infants were randomly divided into a conventional treatment group with 62 infants (treated with PS alone at an initial dose of 200 mg/kg, followed by a dose of 100 mg/kg according to the condition of the infant) and an observation group with 60 infants (treated with PS at the same dose as the conventional treatment group, with the addition of budesonide 0.25 mg/kg for intratracheal instillation at each time of PS application). The two groups were compared in terms of the times of PS use, ventilator parameters at different time points, oxygen inhalation, incidence rate and severity of BPD, incidence rate of complications, and tidal breathing pulmonary function at the corrected gestational age of 40 weeks. Results Compared with the conventional treatment group, the observation group had a significantly lower proportion of infants using PS for two or three times (P<0.05). Compared with the conventional treatment group, the observation group had a significantly lower fraction of inspired oxygen at 24 and 48 hours and 3, 7, and 21 days after administration, significantly shorter durations of invasive ventilation, noninvasive ventilation, ventilator application, and oxygen therapy, a significantly lower incidence rate of BPD, and a significantly lower severity of BPD (P<0.05). There was no significant difference in the incidence rate of glucocorticoid-related complications between the two groups (P>0.05). Conclusions Compared with PS use alone in preterm infants with a high risk of BPD, budesonide combined with PS can reduce repeated use of PS, lower ventilator parameters, shorten the duration of respiratory support, and reduce the incidence rate and severity of BPD, without increasing the incidence rate of glucocorticoid-related complications.

Value of heparin-binding protein in the diagnosis of severe infection in children: a prospective study
Objective To study the value of heparin-binding protein (HBP) in the diagnosis of severe infection in children. Methods This study was a prospective observational study. The medical data of children who were admitted to the pediatric intensive care unit due to infection from January 2019 to January 2020 were collected. According to the diagnostic criteria for severe sepsis and sepsis, the children were divided into a severe sepsis group with 49 children, a sepsis group with 82 children, and a non-severe infection group with 33 children. The three groups were compared in terms of related biomarkers such as plasma HBP, serum C-reactive protein, serum procalcitonin, and platelet count. The receiver operating characteristic (ROC) curve was plotted to investigate the value of plasma HBP level in the diagnosis of severe infection (including severe sepsis and sepsis). Results The severe sepsis and sepsis groups had a significantly higher plasma HBP level on admission than the non-severe infection group (P<0.05). Compared with the sepsis and non-severe groups, the severe sepsis group had significantly higher serum levels of C-reactive protein and procalcitonin and a significantly lower platelet count (P<0.05). Plasma HBP level had an area under the ROC curve of 0.590 in determining severe infection, with a sensitivity of 38.0% and a specificity of 82.4% (P<0.05). Conclusions There is an increase in plasma HBP level in children with severe infection, and plasma HBP level has a lower sensitivity but a higher specificity in the diagnosis of severe infection and can thus be used as one of the markers for the judgment of severe infection in children.

Application of fractional exhaled nitric oxide and nasal nitric oxide in control evaluation of bronchial asthma and diagnosis of allergic rhinitis in children
Objective To study the association of fractional exhaled nitric oxide (FeNO) and nasal nitric oxide (nNO) with asthma control and their value in the diagnosis of allergic rhinitis in children. Methods A total of 186 children aged 5-12 years, who attended the outpatient service of the Department of Respiration, Shanghai Children's Hospital due to bronchial asthma and/or allergic rhinitis or who underwent physical examination, were enrolled as subjects, with 52 children in the asthma group, 60 children in the asthma+allergic rhinitis group, 36 children in the allergic rhinitis group, and 38 children in the control group. FeNO, nNO, and pulmonary function were compared between groups. Results The asthma+allergic rhinitis, asthma, and allergic rhinitis groups had a significantly higher level of FeNO than the control group (P<0.05). The asthma+allergic rhinitis and allergic rhinitis groups had a significantly higher level of nNO than the asthma and control groups (P<0.05). The uncontrolled asthma and partially controlled asthma groups had significantly higher levels of FeNO and nNO than the completely controlled asthma group (P<0.05). The receiver operating characteristic (ROC) curve analysis showed that nNO had an area under the ROC curve of 0.91, with a sensitivity of 80.0% and a specificity of 89.5% in the diagnosis of allergic rhinitis in children with asthma (P<0.05). Conclusions The combined measurement of nNO and FeNO can be used to evaluate the control of asthma, and the measurement of nNO can help with the diagnosis of allergic rhinitis in children with bronchial asthma.

Risk factors for the colonization or infection of carbapenem-resistant Enterobacteriaceae in children: a Meta analysis
Objective To systematically assess the risk factors for the colonization or infection of carbapenem-resistant Enterobacteriaceae in children. Methods PubMed, Web of Science, China National Knowledge Infrastructure Database, Wanfang Data, China Biology Medicine disc were searched to obtain the articles on risk factors for the colonization or infection of carbapenem-resistant Enterobacteriaceae in children published up to May 31, 2021. RevMan 5.3 software was used to perform the Meta analysis. Results A total of 13 articles were included, with 1 501 samples in total. The Meta analysis showed that indwelling gastric tube (OR=4.91), tracheal intubation (OR=5.03), central venous catheterization (OR=3.75), indwelling urinary catheterization (OR=4.11), mechanical ventilation (OR=3.09), history of hospitalization in the intensive care unit (OR=2.39), history of surgical operation (OR=3.22), previous use of third-generation cephalosporins (OR=2.62), previous use of carbapenem antibiotics (OR=3.82), previous use of glycopeptide antibiotics (OR=3.48), previous use of β-lactamase inhibitors (OR=2.87), previous use of antifungal drugs (OR=2.48), previous use of aminoglycoside antibiotics (OR=2.54), and Apgar score ≤7 at 1 minute after birth (OR=2.10) were risk factors for the colonization or infection of carbapenem-resistant Enterobacteriaceae in children (P<0.05). Conclusions Invasive operations, history of hospitalization in the intensive care unit, previous use of antibiotics such as carbapenem antibiotics, and Apgar score ≤7 at 1 minute after birth are risk factors for the colonization or infection of carbapenem-resistant Enterobacteriaceae in children.

Recent research on the effect of preeclampsia on maternal-infant intestinal flora interactions
Preeclampsia (PE) is a unique complication of pregnancy that affects the health of the mother and the infant. Intestinal flora plays an important regulatory role in human body's metabolism and immunity and is associated with many diseases. Studies have shown that the development and progression of PE can lead to alterations in intestinal flora in the mother and are even closely associated with the colonization and development of intestinal flora in the offspring. This article reviews related studies on the effect of PE on maternal-infant intestinal flora, so as to provide new ideas for the prevention and treatment of maternal and infant complications associated with PE.

Recent research on the mechanism of mesenchymal stem cells in the treatment of bronchopulmonary dysplasia
Bronchopulmonary dysplasia (BPD) is a chronic lung disease due to impaired pulmonary development and is one of the main causes of respiratory failure in preterm infants. Preterm infants with BPD have significantly higher complication and mortality rates than those without BPD. At present, comprehensive management is the main intervention method for BPD, including reasonable respiratory and circulatory support, appropriate enteral nutrition and parenteral nutrition, application of caffeine/glucocorticoids/surfactants, and out-of-hospital management after discharge. The continuous advances in stem cell medicine in recent years provide new ideas for the treatment of BPD. Various pre-clinical trials have confirmed that stem cell therapy can effectively prevent lung injury and promote lung growth and damage repair. This article performs a comprehensive analysis of the mechanism of mesenchymal stem cells in the treatment of BPD, so as to provide a basis for clinical applications.
