Neonatal outcomes of very preterm infants from a neonatal intensive care center

Background:Information about clinical outcomes of very preterm(VPT)infants in tertiary neonatal intensive care unit(NICU)setting is scant in China.This study aimed to investigate the mortality and morbidity of VPT infants admitted to BaYi Children’s Hospital,which serves as a NICU referral center for the city of Beijing,China.Methods:Retrospectively collected perinatal/neonatal data on all admissions of infants born at<32 weeks of gestational age and subsequently admitted to the VPT-NICU from clinical records between October 2010 and September 2011.Results:Totally 729 infants were identified.90%of VPT infants were outborn.The overall survival of the infants to discharge was 92%,which increased with increasing gestational age(range from 69%at<28 weeks to 99%at 31 weeks).The incidence of bronchopulmonary dysplasia was 4%,retinopathy of prematurity requiring treatment 2%,intraventricular hemorrhage III-IV 6%,and periventricular leukomalacia 2%.10%of the VPT infants had a major morbidity at discharge.Conclusions:The outcomes of the VTP infants at this referral NICU were comparable to those in tertiary centers in developed countries.The most common complications were lower than those in other cohorts.Accordingly,high-volume NICU may minimize the adverse effects of VPT infants’transport.

Neurodevelopmental Outcomes of Extremely Premature Infants with Extremely Low and Very Low Birth Weight at Three Years of Age: A Retrospective Study

Introduction: The purpose of this retrospective study is to identify medical conditions impacting neurodevelopmental outcomes of extremely low birth weight and very low birth weight preterm infants at three years of age. Methods: Infants born in Banner Diamond Children’s University Medical Center, receiving services in the Newborn Intensive Care Unit, and attending Neonatal Developmental Follow-Up Clinic were identified. Participants received developmental assessment and follow-up from August 2012 through December 2018. Relevant clinical conditions during initial hospital stay and up to three years of age were obtained by reviewing medical and developmental records. Bayley Scales of Infant Toddler Development (Bayley III) was used to evaluate skill development at 6, 9, 12, 18, 24, 30, 36 months. Results: Data analysis did not reveal significant p-values;it did demonstrate that some predictor variables impact neurodevelopmental outcomes in cognitive, language and motor skill development. Conclusion: This retrospective study reports significant association between birth weight and low cognitive scores. Correlations were also found between gestational age and Total Language, and the longer an infant stayed in the NICU, the poorer the Total Language Scaled Scores at 8 to 12 months, 15 to 18 months, and 24 to 36 months. Birth weight was found to be the greatest predictor of poor motor scores.

Outcome of Very Premature Newborns in a Referral Hospital in a Resource-Limited Setting

Background: In Cameroon, prematurity is considered among the first cause of neonatal mortality and the main cause of sequelae in children under 5 years old. Although some local teams have studied the causes of neonatal deaths, the survival of the very preterm babies in our context remains poorly known. Patients and Methods: We conducted a hospital-based cross-sectional study with both a retrospective and prospective data collection, covering a period of 5 years and 8 months, including 120 participants who presented with very preterm birth. Socio-demographic, anamnestic, and outcome features were studied. The assessment of the child’s psychomotor development was evaluated trough gross motor skills, fine motor skills, language and social contact. We calculated the development quotient (DQ) by dividing the developmental age (DA) by the actual age (RA) of the patient. Qualitative variables were expressed as numbers and percentages and quantitative variables as means ± standard deviations. Results: At the clinic, 23.8% of the children developed cerebral palsy, 3.1% had cerebral palsy with mental delay, and 6.6% had praxis disorders. Hearing impairment was observed in 6.3% of the survivors, visual impairment in 9%, and swallowing disorders in 7.6%. The mean developmental quotient was (89.98 ± 19.7) with a median of 93. A delay in developmental milestones was observed in 10.8%, speech disorder in 57%, severe malnutrition in 7.7%. The mortality rate was 48.5%. Conclusion: Very preterm birth is associated with a higher risk of neonatal death. Cognitive and motor disorders should not be underestimated. The harmonised management of very premature babies is highly recommended in our context for early diagnosis of sequelae.

Association between Prenatal Care Utilization and Risk of Preterm Birth among Chinese Women

It is recognized that prenatal care plays an important role in reducing adverse birth. Chinese pregnant women with medical condition were required to seek additional health care based on the recommended at least 5 times health care visits. This study was to estimate the association between prenatal care utilization（PCU） and preterm birth（PTB）, and to investigate if medical conditions during pregnancy modified the association. This population-based case control study sampled women with PTB as cases; one control for each case was randomly selected from women with term births. The Electronic Perinatal Health Care Information System（EPHCIS） and a questionnaire were used for data collection. The PCU was measured by a renewed Prenatal Care Utilization（APNCU） index. Logistic regression models were used to estimate odds ratios（OR） and the 95% confidence interval（95% CI）. Totally, 2393 women with PTBs and 4263 women with term births were collected. In this study, 695（10.5%） women experienced inadequate prenatal care, and 5131（77.1%） received adequate plus prenatal care. Inadequate PCU was associated with PTB（adjusted OR： 1.41, 95% CI： 1.32–1.84）; the similar positive association was found between adequate plus PCU and PTB. Among women with medical conditions, these associations still existed; but among women without medical conditions, the association between inadequate PCU and PTB disappeared. Our data suggests that women receiving inappropriate PCU are at an increased risk of having PTB, but it does depend on whether the woman has a medical condition during pregnancy.

Use of antenatal corticosteroids among infants with gestational age at 24 to 31 weeks in 57 neonatal intensive care units of China: a cross-sectional study

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.
