BACKGROUND
Maternal malnutrition is a major cause of low birth weight (LBW) newborn outcome especially among adolescent mothers. It is one of the key drivers of child stunting and initiates the vicious cycle of intergenerational malnutrition. The body mass index prior to pregnancy or at the initial trimester is currently being used to establish the desired weight gain throughout pregnancy. However, Filipino adolescents often delay their first antenatal visit at a later stage of pregnancy. Without a baseline weight, the establishment of appropriate weight gain and nutritional status is often challenging. Mid-upper arm circumference (MUAC) was proven to be a good proxy measure of acute malnutrition, however, there was no global consensus on what MUAC cut-off point to use to identify pregnant adolescents at risk for delivering LBW babies. Finding the optimal cut-off could facilitate early identification and intervention of pregnant adolescents who are nutritionally at risk and could eventually break the cycle of intergenerational malnutrition.
OBJECTIVESThe study aims to determine the association of maternal MUAC and the birth weight outcomes among newborn deliveries of adolescents in a tertiary hospital for a period of six months and to identify the optimal maternal MUAC cut-off point that can be used to predict low birth weight outcome among newborn deliveries of adolescents in a tertiary hospital.
METHODSA cross-sectional study was conducted among adolescents ages 10 to 19 years who delivered babies in a tertiary hospital in the Philippines for a period of six months. Maternal MUAC and LBW outcome were documented, and their association was determined using a logistic regression analysis. To measure diagnostic accuracy, the sensitivity, specificity, and the area under the curve were taken for each MUAC point. A receiver operating characteristic (ROC) curve was used to aid the MUAC cut-off determination.
RESULTSOut of 237 newborn deliveries, 35% were noted with low birth weight while 65% had normal birth weight. Most of the mothers were in their late adolescence at 78%. The crude association for the MUAC cut-offs ≤23.00 cm, ≤23.50 cm, and ≤24.00 cm and LBW showed a significant value of 2.19, 2.25, and 2.39 at 95% CI, respectively. However, it is only the cut-off ≤24.00 cm that showed significant results for adjusted association by the logistic regression analysis. The MUAC cut-off ≤24.00 cm also showed a better trade-off value between the sensitivity and specificity. Furthermore, the optimal maternal MUAC measurement that predicts LBW newborn outcome points to ≤24.00 cm cut-off based on the ROC curve.
CONCLUSIONThis study shows that the maternal MUAC is predictive of LBW outcome among adolescent deliveries.A MUAC cut-off of ≤24.00 cm was superior to lower cut-offs studied. The pregnant adolescents might need a higher MUAC cut-off than adults to allow timely intervention and prevention of poor neonatal outcomes. By doing this simple screening test, suspected pregnant adolescents can be easily identified and referred for further confirmatory testing.

OBJECTIVES:
To evaluate the effect of colostrum oral immune therapy (COIT) on clinical outcomes in very low birth weight (VLBW) infants.
METHODS:
A computer-based search was conducted in databases including China National Knowledge Infrastructure, Wanfang Data, Weipu Database, Chinese Biomedical Literature Service System, PubMed, Embase, Web of Science, the Cochrane Library, and CINAHL for randomized controlled trials regarding the application of COIT in VLBW infants published from the establishment of the database to February 2024. Meta analysis was performed using RevMan 5.3 software.
RESULTS:
A total of 14 randomized controlled trials were included, involving 1 386 VLBW infants, with 690 in the COIT group and 696 in the control group. The results showed that COIT significantly reduced the incidence of clinical late-onset sepsis (LOS) (RR=0.75, 95%CI: 0.64-0.88, P<0.001), the incidence of blood culture-proven LOS (RR=0.72, 95%CI: 0.57-0.92, P=0.008), mortality rate (RR=0.70, 95%CI: 0.52-0.95, P=0.020), the incidence of necrotizing enterocolitis (RR=0.65, 95%CI: 0.46-0.92, P=0.020), and the incidence of feeding intolerance (RR=0.49, 95%CI: 0.29-0.80, P=0.004). It also shortened the time to achieve full enteral nutrition (MD=-2.13, 95%CI: -4.03 to -0.23, P=0.030).
CONCLUSIONS
COIT can reduce the incidence rates of LOS, necrotizing enterocolitis, and feeding intolerance, as well as the mortality rate, while also shortening the time to achieve full enteral nutrition in VLBW infants.

OBJECTIVES:
To investigate the incidence of small for gestational age (SGA) infants among singleton live births and identify risk factors.
METHODS:
Clinical data for 1 020 singleton live-born infants and their mothers at People's Hospital Affiliated to Shandong First Medical University from January 2019 to January 2024 were retrospectively collected. The incidence of SGA was calculated, and univariate and multivariable logistic regression analyses were performed to determine independent risk factors.
RESULTS:
Among 1 020 singleton live births, the incidence of SGA was 9.90%. SGA was more frequent in female neonates and in cases with lower placental weight or umbilical cord abnormalities (all P<0.05). Both preterm and post-term birth showed significant linear trends with SGA incidence (P<0.05). Maternal factors associated with higher SGA incidence included age <20 years or ≥35 years, primary-school education or below, low pre-pregnancy body mass index (BMI), insufficient gestational weight gain, gestational hypertension, diabetes, anemia, hyperthyroidism, hypothyroidism, amniotic fluid/placental abnormalities, and smoking history (all P<0.05). Multivariable logistic regression identified preterm birth, post-term birth, low placental weight, umbilical cord abnormalities, low pre-pregnancy BMI, insufficient gestational weight gain, gestational hypertension, anemia during pregnancy, and maternal smoking as independent risk factors for SGA (all P<0.05).
CONCLUSIONS
The occurrence of SGA among singleton live births is associated with preterm or post-term delivery, low placental weight, umbilical cord abnormalities, low pre-pregnancy BMI, inadequate gestational weight gain, gestational hypertension, anemia during pregnancy, and maternal smoking. Targeted strengthening of perinatal management is warranted to reduce the risk of SGA.

OBJECTIVES:
To explore the status and risk factors of neuropsychological development in small for gestational age (SGA) infants at corrected 12-24 months of age.
METHODS:
Clinical data were retrospectively collected for 754 SGA infants at corrected ages 12-24 months in Shenzhen Bao'an Women and Children's Hospital between April 2018 and December 2023. Developmental quotient (DQ) levels were analyzed. According to the presence of global developmental delay (GDD), participants were divided into a GDD group (71 cases) and a control group (683 cases), and the incidence and influencing factors of GDD were investigated.
RESULTS:
In the high-risk preterm SGA group, the total DQ and DQ in all domains were lower than in the full-term SGA group (P<0.017). The overall incidence of GDD was 9.4% (71/754) and increased with decreasing gestational age (P<0.017). Compared with the control group, the GDD group had higher proportions of males; low-risk and high-risk preterm birth; mothers with less than a bachelor's degree; multiple birth; neonatal hypoglycemia; neonatal pneumonia; neonatal respiratory distress syndrome; bronchopulmonary dysplasia; and, at corrected 12-24 months, low body weight, growth retardation, and microcephaly. The length of neonatal hospital stay was longer in the GDD group than in the control group (P<0.05). The weight-for-age Z score, length-for-age Z score, and head circumference-for-age Z score at birth and at corrected 12-24 months were lower in the GDD group than in the control group (P<0.05). Multivariable logistic regression showed that male sex and maternal education below a bachelor's degree were independent risk factors for GDD in SGA infants (P<0.05).
CONCLUSIONS
Neuropsychological development in preterm SGA infants is comparatively delayed; male SGA infants born to mothers with less than a bachelor's degree should receive priority attention.

Objective: To establish neonatal birthweight percentile curves based on single-center cohort database using different methods, compare them with the current national birthweight curves and discuss the appropriateness and significance of single-center birthweight standard. Methods: Based on a prospective first-trimester screening cohort at Nanjing Drum Tower Hospital from January 2017 to February 2022, the generalized additive models for location, scale and shape (GAMLSS) and semi-customized method were applied to generate local birthweight percentile curves (hereinafter referred to as the local GAMLSS curves, semi-customized curves) for 3 894 cases who were at low risk of small for gestation age (SGA) and large for gestation age (LGA). Infants were categorized as SGA (birth weight<10th centile) by both semi-customized and local GAMLSS curves, semi-customized curves only, or not SGA (met neither criteria). The incidence of adverse perinatal outcome between different groups was compared. The same method was used to compare the semi-customized curves with the Chinese national birthweight curves (established by GAMLSS method as well, hereinafter referred to as the national GAMLSS curves). Results: (1) Among the 7 044 live births, 404 (5.74%, 404/7 044), 774 (10.99%, 774/7 044) and 868 (12.32%, 868/7 044) cases were diagnosed as SGA according to the national GAMLSS curves, the local GAMLSS curves and the semi-customized curves respectively. The birth weight of the 10th percentile of the semi-customized curves was higher than that of the local GAMLSS curves and the national GAMLSS curves at all gestational age. (2) When comparing semi-customized curves and the local GAMLSS curves, the incidence of admission to neonatal intensive care unit (NICU) for more than 24 hours of infants identified as SGA by semi-customized curves only (94 cases) and both semi-customized and local GAMLSS curves (774 cases) was 10.64% (10/94) and 5.68% (44/774) respectively, both significantly higher than that in non SGA group [6 176 cases, 1.34% (83/6 176); P<0.001]. The incidence of preeclampsia, pregnancy<34 weeks, and pregnancy<37 weeks of infants identified as SGA by the semi-customized curves only and both semi-customized and local GAMLSS curves was 12.77% (12/94) and 9.43% (73/774), 9.57% (9/94) and 2.71% (21/774), 24.47% (23/94) and 7.24% (56/774) respectively, which were significantly higher than those of the non SGA group [4.37% (270/6 176), 0.83% (51/6 176), 4.23% (261/6 176); all P<0.001]. (3) When comparing semi-customized curves and the national GAMLSS curves, the incidence of admission to NICU for more than 24 hours of infants identified as SGA by semi-customized curves only (464 cases) and both semi-customized and national GAMLSS curves (404 cases) was 5.60% (26/464) and 6.93% (28/404) respectively, both significantly higher than that in non SGA group [6 176 cases, 1.34% (83/6 176); all P<0.001]. The incidence of emergency cesarean section or forceps delivery for non-reassuring fetal status (NRFS) in infants identified as SGA by semi-customized curves only and both semi-customized and national GAMLSS curves was 4.96% (23/464) and 12.38% (50/404), both significantly higher than that in the non SGA group [2.57% (159/6 176); all P<0.001]. The incidence of preeclampsia, pregnancy<34 weeks, and pregnancy<37 weeks in the semi-customized curves only group and both semi-customized and national GAMLSS curves group was 8.84% (41/464) and 10.89% (44/404), 4.31% (20/464) and 2.48% (10/404), 10.56% (49/464) and 7.43% (30/404) respectively, all significantly higher than those in the non SGA group [4.37% (270/6 176), 0.83% (51/6 176), 4.23% (261/6 176); all P<0.001]. Conclusion: Compared with the national GAMLSS birthweight curves and the local GAMLSS curves, the birth weight curves established by semi-customized method based on our single center database is in line with our center' SGA screening, which is helpful to identify and strengthen the management of high-risk infants.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

9.A multicenter prospective cohort study of late-onset sepsis and its poor prognosis in very low birth weight infants.
Chinese Journal of Pediatrics 2023;61(3):228-234
Objective: To investigate the prevalence and poor prognosis of late-onset sepsis (LOS) in very low birth weight infant (VLBWI). Methods: This prospective, multicenter observational cohort study was conducted based on the data from Sina-Northern Neonatal Network (SNN). The general data, perinatal information and poor prognosis of 6 639 VLBWI, who were admitted to the 35 neonatal intensive care units from 2018 to 2021, were collected and analyzed. According to the occurrence of LOS during hospitalization, the VLBWI were assigned to the LOS group and non-LOS group. The LOS group was further divided into 3 subgroups according to the occurrence of neonatal necrotizing enterocolitis (NEC) and purulent meningitis. The Chi-square test or Fisher exact probability method, independent sample t test, Mann-Whitney U test and multivariate Logistic regression model were used to analyze the relationship between LOS and poor prognosis in VLBWI. Results: A total of 6 639 eligible VLBWI were enrolled, including 3 402 cases (51.2%) of males and 1 511 cases (22.8%) with LOS. The incidences of LOS in extremely low birth weight infants (ELBWI) and extremely preterm infants were 33.3% (392/1 176) and 34.2% (378/1 105), respectively. There were 157 cases (10.4%) who died in the LOS group and 48 cases (24.9%) in the subgroup of LOS complicated with NEC. Multivariate Logistic regression analysis showed that LOS complicated with NEC was associated with increased mortality and incidence of grade Ⅲ-Ⅳ intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL), moderate or severe bronchopulmonary dysplasia (BPD), and extrauterin growth retardation (EUGR) (ORadjust=5.27, 2.59, 3.04, 2.04; 95%CI 3.60-7.73, 1.49-4.50, 2.11-4.37, 1.50-2.79; all P<0.01); LOS complicated with purulent meningitis was also associated with increased mortality and incidence of grade Ⅲ-Ⅳ IVH or PVL, and moderate or severe BPD (ORadjust=2.22, 8.13, 3.69, 95%CI 1.30-3.37, 5.22-12.67, 2.49-5.48; all P<0.01); the infants without NEC or purulent meningitis in the LOS group was only associated with increased incidence of moderate or severe BPD (ORadjust=2.20, 95%CI 1.83-2.65, P<0.001). After ruling out contaminated bacteria, a total of 456 cases showed positive blood culture, including 265 cases (58.1%) of Gram-negative bacteria, 126 cases (27.6%) of Gram-positive bacteria, and 65 cases (14.3%) of fungi. The most common pathogenic bacteria was Klebsiella pneumoniae (n=147, 32.2%), followed by coagulase-negative Staphylococcus (n=72, 15.8%) and subsequently Escherichia coli (n=39, 8.6%). Conclusions: The incidence of LOS is high in VLBWI. Klebsiella pneumoniae is the most common pathogenic bacteria, followed by coagulase-negative Staphylococcus and Escherichia coli. LOS is associated with a poor prognosis for moderate to severe BPD. The prognosis of LOS complicated with NEC is poor with the highest mortality, and the risk of brain damage is significantly increased when LOS complicated with purulent meningitis.

10.Outcome of neonates born to mothers with chronic kidney disease.
Chinese Journal of Contemporary Pediatrics 2023;25(1):104-108
About 3% of pregnant women suffer from chronic kidney disease (CKD). This article reviews the literature on the outcomes of neonates born to mothers with CKD (including those undergoing dialysis and kidney transplantation), and the results show that CKD during pregnancy may increase the risk of preterm birth, low birth weight, and small for gestational age infant, but it does not increase the risk of congenital anomalies. As for long-term outcomes, CKD during pregnancy has no significant impact on offspring's physical development and immune function. Neurodevelopmental outcome of offspring is associated with preterm birth and low birth weight, rather than intrauterine drug exposure. However, further research and follow-up are needed to investigate the outcome of neonates born to mothers with CKD.
