Advance in postnatal catch-up growth and insulin resistance in small for gestational age infants / 中华围产医学杂志

Small for gestational age (SGA) infants usually result from fetal growth restriction. After eliminating harmful factors, catch-up growth occurs in most SGA as a compensatory mechanism of children's growth and development. Many studies conclude that catch-up growth could lead to insulin resistance early in life. However, the mechanism remains unclear, which results in a lack of clinical intervention to reduce or even avoid insulin resistance. This review sums up studies on catch-up growth and insulin resistance. It describes the possible mechanism of suppressed thermogenesis and catch-up fat, stress, inflammation, DNA methylation, etc., to provide a theoretical foundation for clinical practice.

Risk factors of neonatal asphyxia in twin pregnancy / 中华围产医学杂志

Objective:To investigate the incidence and risk factors of neonatal asphyxia in twin pregnancy.Methods:This study retrospectively recruited 2 035 women with twin pregnancy and their 4 070 twin neonates in the Obstetrics and Gynecology Hospital of Fudan University from January 2010 to December 2018. There were 211 cases suffered from neonatal asphyxia (asphyxia group) and 3 859 did not (non-asphyxia group). The demographic information of the women and their newborns and the incidence of perinatal complications were compared between the two groups by two independent samples t-test and Chi-square test. Multivariate logistic regression was used to analyze the risk factors of neonatal asphyxia in twin pregnancy. Results:The age of 2 035 women was (31.8±4.4) years old (17-52 years old). The gestational age of the twins at delivery was (35.2±2.2) weeks (25-40 weeks). There were 1 330 (65.4%) premature births, including 997 (49.0%) born at ≥34 weeks. Monochorionic diamniotic twin pregnancies accounted for 22.6% (460/2 035). The total incidence of neonatal asphyxia was 5.2% (211/4 070), 5.0% (102/2 035) in the first- and 5.4% (109/2 035) in the second-born twin infants, and the three figures were all decreased with the increase of gestational age ( χ2trend=1 601.965, 549.693 and 1 089.709, all P<0.001) as well as birth weight ( χ2trend=1 273.386, 437.906 and 848.007, all P<0.001). Univariate analysis showed that the asphyxia group had smaller gestational age and lower birth weight [(34.1±2.8) vs (35.3±2.1) weeks, t=6.279; (2 113.3±565.7) vs (2 339.6±478.7) g, t=5.700], but a higher ratio of male infants [58.3% (123/211) vs 48.5% (1 878/3 859), χ2=7.704], vaginal delivery [10.4% (22/211) vs 4.5% (173/3 859), χ2=15.493], monochorionic diamniotic twins [27.5% (58/211) vs 22.3% (862/3 859), χ2=7.714], special complications related to monochorionic diamniotic twin pregnancies [8.1% (17/211) vs 2.5% (95/3 859), χ2=23.403] and fetal distress [13.7% (29/211) vs 3.8% (148/3 859), χ2=47.222] than the non-asphyxia group (all P<0.05). After adjusting for the gestational age, birth weight and gender, multivariate logistic regression found that vaginal delivery ( OR=1.748, 95% CI: 1.069-2.861), special complications related to monochorionic diamniotic twin pregnancies ( OR=3.200, 95% CI: 2.056-4.982) and fetal distress ( OR=2.017, 95% CI: 1.073-3.791) were the risk factors for asphyxia in twin neonates (all P<0.05). Conclusions:The incidence of neonatal asphyxia is high in twins with small gestational age and low birth weight. Vaginal delivery, fetal distress and special complications related to monochorionic diamniotic twin pregnancies are the high-risk factors. Clinicians should be well prepared for resuscitation when encountering neonatal asphyxia.

Cytomegalovirus infection in preterm infants of gestational age <32 weeks or birth weight <1 500 g fed by their own mother's frozen breast milk / 中华围产医学杂志

Objective:To understand cytomegalovirus (CMV) infection status in hospitalized preterm infants who were fed by their own mother's frozen breast milk.Methods:This retrospective study enrolled breastfed neonates with gestational age less than 32 weeks or birth weight less than 1 500 g who were born and admitted to Gynecology and Obstetrics Hospital of Fudan University from January 2018 to December 2020. Clinical data of the babies and their mothers were collected and analyzed, including CMV DNA results of breast milk and urine samples of the subjects by fluorescence quantitative polymerase chain reaction. Chi-square test (or Fisher's exact probability test), two independent samples t test, and Mann-Whitney U test were used for the statistical analysis. Results:A total of 94 parturients and their 103 premature infants (including nine pairs of twins) were included. CMV DNA of breast milk was noted for positive in 75 cases (including eight pairs of twins) and for negative in 28 cases (including one pair of twins). Out of the 75 preterm infants born to mothers with positive CMV DNA breast milk, 67 (including eight pairs of twins) were switched to frozen breast milk (－20 ℃ for 72 h), and six of them were infected by CMV(9.0%) without any treatment. All of the 103 infants were divided into two groups: the frozen milk fed group ( n=67) or fresh milk fed group ( n=36). In the frozen milk fed group, the CMV DNA was mainly detected during 2-8 weeks postpartum with copy number reaching the peak at 8th week. And those infants in the frozen milk fed group, whose mother's breast milk CMV DNA was positive, was further divided into CMV infected ( n=6) or CMV non-infected groups ( n=61) according to the urine test results. Moreover, compared with the non-infected group, the average [22.7(3.0-95.7)×10 3 copies/ml vs 5.0(0.5-89.5)×10 3 copies/ml, Z=－2.218) and the highest[45.9(5.9-261.0)×10 3 copies/ml vs 9.8(1.2-766.0)×10 3 copies/ml, Z=－2.218] copy number of CMV DNA in the breast milk were higher in the CMV infected group (both P<0.05). The incidence of feeding intolerance[37.3% (25/67) vs 50.0% (18/36), χ2=1.550], neonatal necrotizing enterocolitis [0.7% (1/67) vs 0.0% (0/36)], bronchopulmonary dysplasia [28.4% (19/67) vs 27.8% (10/36), χ2=0.004], retinopathy of prematurity [20.9% (14/67) vs 8.3%(3/36), χ2=2.682], and late-onset sepsis [22.4% (15/67) and 30.6% (11/36), χ2=0.828] did not differ significantly between the frozen or fresh milk fed groups (all P>0.05). Conclusions:The incidence of breast milk-related CMV infection in those fed with frozen breast milk was low and does not increase the without increasing risks of related complications or leading to obvious clinical manifestations after infection. For preterm infants with gestational age <32 weeks or birth weight <1 500 g, frozen breast milk can be an alternative for mothers with CMV DNA positive breast milk.

The clinical analysis of pleural effusion associated with peripherally inserted central catheters in two neonates / 临床儿科杂志

Objective To explore the clinical characteristics of pleural effusion associated with peripherally inserted central catheters (PICCs) in neonates. Method The clinical data of pleural effusion caused by PICCs in two neonates were retrospectively analyzed. Results Both 2 cases were preterm female infants. Case 1 was delivered at 26+5 weeks, with a birth weight of 800 g. Dyspnea aggravated 8 hours after the PICC placement. Bedside chest radiograph indicated a large amount of pleural effusion on the right side. PICC was removed, puncture and drainage were performed, and pleural effusion was cured after 6 days of closed thoracic drainage. Case 2 was delivered at 29+3 weeks with a birth weight of 1240 g. Three days after placement of PICC, dyspnea became worse. Bedside chest radiograph showed bilateral pleural effusion, which was cured after PICC removal, puncture and drainage. According to the routine and biochemical indexes of pleural effusion, combined with the medical history, case 1 was consistent with the diagnosis of chylothorax and case 2 was considered as fluid exudation. Conclusion Neonatal PICC-associated pleural effusion is rare, but the etiology is varied and progress is rapid. Vigilance and active treatment is needed in clinic.

Intestinal perforation in one of monochorionic twins: a report of two cases and literature review / 中华围产医学杂志

Objective To report two cases of intestinal perforation in one of monochorionic twins and to analyze relevant clinical manifestations based on literature review. Methods Both cases were admitted to the Obstetrics and Gynecology Hospital of Fudan University in 2017. Relevant articles were retrieved from PubMed, OVID, Elsevier, Full-text Database of China National Knowledge Infrastructure(CNKI) and Wanfang Database from their release dates to February 2018. Clinical manifestations were analyzed through a literature review. Results In case 1, twin boys were born by cesarean section because of selective intrauterine growth restriction (sIUGR) Ⅲ at 31+3gestational weeks. Signs of abdominal distention were found in one boy the day after birth, whose birth weight was 1 440 g and Apgar scores was all 9 at 1, 5 and 10 min after birth. A large amount of intra-abdominal gas was shown on abdominal X-ray. He was cured after surgery and discharged later. The other boy was fine. In case 2, twin girls were born by cesarean section because of twin-twin transfusion syndrome (TTTS) Ⅲ at 29+1gestational weeks. The one suffered from intestinal perforation was 810 g at birth and her Apgar scores was all 8 at 1, 5 and 10 minutes. Pneumoperitoneum were observed on abdominal X-ray 16 h after birth. The baby died because of refusal to further treatment after surgery. The other girl was in good condition. Literature search found no relevant report in mainland China, but ten cases had been reported aboard and five of them died. Most cases of TTTS complicated by intestinal perforation occurred in the recipients. Conclusions Complications of monochorionic twins such as TTTS and sIUGR might be potentially associated with intestinal perforation. Early intervention and evaluation is the key to improve the outcomes.

Clinical features and risk factors of neonatal clavicle fracture / 中华围产医学杂志

ObjectiveTo summarize the clinical features and risk factors of neonatal clavicle fracture so as to decrease the incidence of this disease.MethodsA total of 85 cases of neonatal clavicle fracture admitted to the Gynecology and Obstetrics Hospital of Fudan University between January 1, 2013 and December 31, 2015 were enrolled in this study. The full-term neonates with natural delivery by the same midwives or doctors on the same day were selected as control group with 1∶1 matched. Clinical features and risk factors of neonatal clavicle fracture based on three factors: mother factors, labor factors and neonatal factors, were analyzed retrospectively. Two independent samplest-test, rank sum test andChi-square test were used for statistical analysis.ResultsThe incidence rate of neonatal clavicle fractures was 0.14% (85/59 991). There were 45 (53%) males and 40 (47%) females; 80 (94%) cases of vaginal delivery, and 5 (6%) cases of cesarean section. According to the relationship between the location of the fracture and the position of the fetus, the fracture occurred in the anterior shoulder in 65 cases (76%) and in the posterior shoulder in 20 cases (24%);and 18 cases (21%) were in the left and 67 cases (79%) in the right. Fifty-five cases (65%) were diagnosed by physical examination, and 30 cases (35%) by X-ray. Two patients (2%) were complicated with brachial plexus injury. Twenty cases (24%) were diagnosed on the day of birth, 32 cases (38%) on the second day after birth, 16 (19%) on the third day, and four (5%) on the 4-6 days. Thirteen (15%) cases were diagnosed in the outpatient department 42 days after birth. All the fractures were cured without special treatment. Compared with the control group, the birth weight of fracture group was significantly higher [(3 646±361) vs (3 447±409) g,t=2.339], and the ratio of the cases complicated with shoulder dystocia was also higher [15% (13/85) vs 2% (2/85),χ2=9.524] (bothP<0.05). The differences in the factors of maternal age, parity, times of pregnancy, gestational age, forceps delivery, time of the second stage of labor and fetal distress between the two groups were not statistically significant.ConclusionsNeonatal clavicle fracture is related to birth weight and shoulder dystocia. Not all fractures can be diagnosed through physical examination on the day of birth, therefore, daily routine physical examinations after birth are necessary. The prognosis of neonatal clavicle fracture is good.

Antimicrobial use density and antimicrobial resistance of isolated pathogens in hospitalized patients from 2011 to 2015 / 中国感染控制杂志

Objective To understand the distribution and change in drug resistance of common pathogens before and after the implementation of special rectification activity on antimicrobial use in 2011-2015,and provide guidance for clinical application of antimicrobial agents.Methods Antimicrobial use in hospitalized patients and pathogens isolated from patients in a hospital from 2011 to 2015 were collected,changing trend of resistance rates of major pathogens to commonly used antimicrobial agents was analyzed.Results From 2011 to 2015,antimicrobial utilization rate in hospitalized patients dropped from 75.84%to 37.35%,antimicrobial use density decreased from 59.53 per 100 patient days to 33.63 per 100 patient days,both showed a downward trend(both P<0.05).A total of 10 091 strains of pathogens were isolated,2 338(23.17%)of which were gram-positive bacteria,7 110(70.46%)were gram-negative bacteria,and 643(6.37%)were fungi.The top five pathogens were Escherichia coli(20.85%),Klebsiella pneumoniae(15.90%),Pseudomonas aeruginosa(11.70%),Staphylococcus aureus(7.35%),and Acinetobacter baumannii(6.82%).Resistance rates of major pathogens to commonly used antimicrobial agents decreased year by year(P<0.05),resistance rates of Escherichia coli and Klebsiella pneumoniae to piperacillin/tazobactam,cefoxitin,and amikacin declined most obviously(all<4%in 2015);compared with Acinetobacter baumannii,Pseudomonas aeruginosa had higher sensitivity to commonly used antimicrobial agents,resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,cefepime,amikacin,and ciprofloxacin decreased obviously,resistance rate to above antimicrobial agents was <20%,to carbapenems was higher than other commonly used antimicrobial agents.Resistance rates of Acinetobacter baumannii to amikacin,levofloxacin decreased most obviously,to meropenem and imipenem increased obviously,in 2015 were both above 50%.Resistance rate of Staphylococcus aureus to fluoroquinolones declined most obviously(<2%),vancomycin-resistant strains were not found.Conclusion After the implementation of special rectification activity,resistance rates of common pathogens decreased with the decline of antimicrobial use,rational use of antimicrobial agents may be related to delaying bacterial resistance.

Analysis of related risk factors of neonatal resuscitation dififculty / 临床儿科杂志

Objective To analyze related risk factors in resuscitation difficulty in neonates.MethodsLive birth asphyxia neonates with gestational age≥28 weeks (1 minute Apgar score count of 0-7) were included during January 2011 to October 2015. After resuscitation, the neonates were divided into two groups by 5 minutes Apgar score, successful resuscitation group (Apgar score of 8-10) and poor resuscitation group (Apgar score of 0-7). The analysis of related risk factors was performed. Neonates with poor resuscitation assessed by 5 minutes Apgar were continued being resuscitated. After 20 minutes, these neonates were divided into successful resuscitation group (20 minutes Apgar 8-10) and poor resuscitation group (20 minutes Apgar 0-7). The related risk factors analysis was performed once again. ResultsA total of 743 neonates with asphyxia at one minute were included, among whom 130 cases were poor resuscitation and 613 cases were successful resuscitation at 5 minutes. There were obvious correlations of 5 minutes poor resuscitation with premature delivery, low birth weight, 1 minute Apgar score for 0?~?3, intrapartum infectious fever, abnormal placenta, vaginal bleeding during late pregnancy, twin transfusion syndrome, and fetal malformation (P all?

Monitoring and analysis of birth defects in 73498 infants / 临床儿科杂志

Objective To understand the occurrence and the related risk factors of birth defects. Methods Descriptive analysis was conducted on birth detect surveillance in the infants during January 2008 to June 2014. Results A total of 777 cases of birth defect were detected in 73498 infants, and the incidence of birth defect was 1.06%. The 5 most common birth de-fects were congenital heart disease, multi ifnger (toe), hypospadias, cleft lip, and palate and deformity of external ear. Compared infants born with no birth defects, male, preterm, low birth weight, twin and multiple births and resident were statistically higher in infants with birth defects (P<0.05). The major risk factors of birth defects were the medication history, spontaneous abortion, gestational diabetes mellitus, and family history. Conclusions The incidence of birth defect can be reduced by providing good health care during pre-marriage and pregnant so as to decrease the occurrence of premature infants, twins and multiple births, and low birth weight as well as improving prenatal diagnosis and intensifying birth defects surveillance.

Clinical features of non-immune hydrops fetalis in neonates / 中华围产医学杂志

Objective To summarize the clinical characteristics of neonates with non-immune hydrops fetalis.Methods The clinical data of ten neonates with non-immune hydrops fetalis, who were admitted to the Department of Neonatology, Gynecology and Obstetrics Hospital of Fudan University between January 2012 and June 2014, were retrospectively studied.Prenatal characteristics, causes, clinical features and prognosis were explored and analyzed with descriptive statistical methods.Results (1) One of the ten neonates was diagnosed after birth presented with hydroderma and abdominal distension, and the rest ones were diagnosed antenatally.There were six males and four females, and eight premature and two term neonates with the average gestational age of (33.6±2.4) weeks and birth weight of(2 680±478) g.(2) The mean maternal age was (30.3 ±4.6) years.Two of the mothers had gestational diabetes mellitus and one had gestational diabetes mellitus complicating with hyperthyroidism.The blood types of all mothers were O and Rh(+).None of the mothers were tested for parvovirus B19 and no fetus was reported with abnormal chromosome karyotype in the five cases received fetal karyotype analysis.(3) The average gestational age at initial identification of hydrops fetalis by fetal ultrasound was (31.3 ± 2.4) weeks (25.1～37.0 weeks) among nine cases diagnosed prenatally.By ultrasound screening, there were seven cases with hydrothorax, six with seroperitoneum, five with polyhydramnios and four with hydroderm.(4) Two neonates had normal non-stress test results during labor, and eight were abnormal and suffered from severe neonatal asphyxia at birth and resuscitated by endotracheal intubation.Ten neonates had hydroderm, seven had hydrothorax, six had seroperitoneum and one had hydropericardium.One complicated with multiple malformations and one had chromosome abnormality.Four cases received thoracentesis and three had abdominal paracentesis after parturition.(5) Prognosis: One neonate survived and nine died among which six due to resuscitation failure in delivery room, two died one day after giving up treatment after one day, and one died due to treatment failure six months after birth.(6) The causes of hydrops fetalis were anemia (two cases) and congenital diaphragmatic hemangioma, recurrent atrial premature beat, Down's syndrome, congenital pulmonary lymphangiectasia, paroxysmal supraventricular tachycardia, placental chorioangioma, suspicious genetic syndrome and idiopathic (one for each).Conclusions The prognosis varies because of different etiology of non-immune hydrops fetalis.Neonates with hydrops fetalis might have a higher rate of asphyxia and mortality rate, and difficulties in resuscitation at birth.

Report a case of congenital pulmonary lymphangiectasia with fetal pleural effusions / 临床儿科杂志

ObjectiveTo summarize and review the clinical characteristics of congenital pulmonary lymphangiectasia with fetal bilateral pleural effusions.MethodsThe clinical data of a newborn diagnosed as congenital pulmonary lymphangiec-tasia with bilateral pleural effusions in Obstetrics and Gynecology Hospital, was summarized. The clinical, radiographic features, treatment and prognosis of this case are discussed in the context of the literature review.ResultsThe premature infants present-ed with rapid progression bilateral pleural effusions, respiratory distress, chylothorax, hypoalbuminemia and persistent pulmo-nary hypertension at birth. The pulmonary surfactant was given and mechanical ventilation was used for respiratory support. NO was inhaled, high-frequency mechanical ventilation was applied and albumin was repeatedly administered. After treatment for 3 months in the NICU, the patient was discharged. After 10 days, the patient was administered to the PICU with severe pneumo-nia, chronic lung disease, mechanical ventilation and anti-infection treatments were applied for 2 months. After living for six months, the baby died.ConclusionsCongenital pulmonary lymphangiectasia is extremely rare and prenatal diagnosis was dif-ifcult. The disease should be considered in patients presented with progressive dyspnea, interstitial emphysema after birth. Lung tissue biopsy and radioisotope scanning should be performed in time to get diagnosis.

Clinical significance of combining second trimester serum and ultrasound screening for Down syndrome / 临床儿科杂志

objectives To explore the clinical significance of the triple screening method and fetal sonographic markers in Down syndrome screening. Methods The retrospective study included maternal blood serum triple-marker screening per-formed in normal singleton pregnancies at 14+1 to 19+6 weeks and ultrasonography screening for fetal chromosomal trisomy at 18+1 to 23+6 weeks from 2010 to 2013. Results In 24 368 pregancies, Karyotype analysis reveal 35 Down syndromes, the incidence is 0.14%(35/24 368). 25/35 were pregnancies with an expected date of delivery lower than 35 years old and 10/35 were pregnan-cies with an expected date of delivery higher than 35 years old. In 1 215 pregnancies, second-trimester serum screening showed high risk (cutoff>1:380), 14 were confirmed as Down syndromes ( sensitivity 40%;specificity 95.06%). In 1 142 pregnant women showed ultrasonography abnormalities, of which 11 were found to have Down syndrome (sensitivity 60%;specificity 91.09%). In 112 pregnancies, second-trimester serum screening and ultrasonography showed high risk, 4 were conformed as Down syn-drome (sensitivity 11.43%;specificity 99.56). Conclusions The most effective method of screening for Down syndrome is by maternal serum biochemistry. Ultrasonography is important in screening fetal trisomy 21. combined screening methods can improve the detection rate of trisomy 21.

The reference ranges of oxygen saturation and heart rate in healthy infants during the first ten minutes after birth / 临床儿科杂志

Objective To establish the reference ranges of preductal oxygen saturation (SpO2) and heart rate (HR) for healthy neonates in 10 minutes after birth. Methods SpO2 and HR recordings of 203 term neonates (vaginal group:n=97 and ce-sarean group:n=106) with regular respiratory pattern were evaluated. 10th-95th percentile charts of SpO2 and HR from 1 minute to 10 minutes after birth were drawn. Results The SpO2 of P10, P50 and P95 at 1 minute after birth was 62%, 71%and 85%respec-tively. The heart rate of P10, P50 and P95 at 1 minute after birth was 66 bpm, 98 bpm and 126 bpm respectively. The median time for SpO2 to reach 90%was 5 minutes. The rising trend of HR was evident during 1-5 minutes after birth, and then the HR leveled off. Conclusions The status of newborn can be assessed using the charts of SpO2 and HR combined with clinical manifestations. The oxygen intervention should be used with care to avoid damage caused by hyperoxemia and hypoxemia.
