Surfactant Replacement Guided by Early Lung Ultrasound Score in Preterm Newborns With Respiratory...
Preterm BirthLung immaturity is a major issue in neonatal unit.The surfactant administration improves the pulmonary prognosis in premature infants with hyaline membrane disease who escape continuous positive airway pressure (CPAP). This surfactant had been administered at 5h25min of life in Saint Etienne from 2016 to 2019. Studies suggest that the earlier the surfactant is administered, the more it can reduce the rate of bronchodysplasia and mortality. And some studies show a pulmonary ultrasound could help to administrate the surfactant earlier This is why a new faster strategy for diagnosing preterms needing surfactant will be usefulness and have been done in Saint-Etienne since 2021 thanks to a ultrasound score (LUS).
Auditory Environment by Parents of Preterm Infants
Infant DevelopmentPreterm Birth1 moreData on parent-infant physical closeness and infants' auditory environment will be collected among preterm infants when they are at gestational age of 32 to 34 weeks. The follow-up includes eye-tracker test at 7 months of corrected age for face preferences of the infants and simultaneously parents' eye movements and pupil diameter responses. During the second year, the follow up includes MacArthur Communicative Development Inventories (lexical development) at 12 and 24 months of age; language development test (Reynell Developmental Language Scales III) and developmental test (Bayley Scales for Infant development Edition III) at 24 months of corrected age.

Comparison of the Results of Premature Babies Started Complementary Feeding
Premature BirthFeeding BehaviorNeurological-developmental evaluations and developmental outcomes-diagnoses of premature babies are evaluated according to corrected postnatal age. Based on the limited evidence available, it can be concluded that complementary feeding may be an appropriate age for most premature babies who have reached at least the third month, generally corrected. However, for premature babies born at different gestational weeks, these periods have a relatively different meaning. A more accurate timeframe can be found in terms of complementary nutrition by evaluating chronological age and motor development together. More prospective observational studies are needed in this regard in premature babies. In the literature, there are not enough studies on the transition time to the most appropriate complementary diet for premature babies. The investigators planned to do this prospective observational study. In this study, patient groups will be randomly selected after appropriate matching. Premature babies participating in the study will be handled in three main groups (six subgroups in total). The data will be added to the case report forms. In addition to routine follow-ups, families will be called on the phone monthly, information about their babies' nutrition will be asked, whether there is a problem, questions of families will be answered, and information about complementary nutrition will be provided. At the end of the study, all data will be collected and entered into the SPSS database, which will be created.
Fetal Viability Estimation in Egypt
Premature BirthMiscarriageDue to the discrepancy between the Egyptian and the conventional definition of miscarriage or live birth, there seemed to be a need for a study that ends up with reaching a definition for the mentioned terms. live birth is known to be for fetus born after 20 weeks or of weight more than 500 grams, while in Egypt, this is not applicable. basically the neonate has a chance of survival if the weight is more than 1000 grams or of gestational age more than 26 weeks.

Executive Function in Preterm Born Children: An Integrative Approach From Genetics to Brain Function...
Preterm InfantsHd-EEG and MRI measures are used to study the maturation of functional networks in order to identify the neural circuits underlying executive and memory processes in children born preterm. It will be determined whether children born preterm with executive function deficits will have an abnormal connectivity between basal ganglia and cortex due to WM injury. Moreover, the development of hd-EEG activity during sleep (coherence and travelling waves) and brain maturation of children and adolescents born preterm will be compared with the respective measures in healthy controls. This is of eminent importance as it helps to understand the nature of executive function and hence, it may help to develop neuroprotective strategies to prevent executive function deficits in these infants.
Neurophysiologic Maturation Index for Moderate and Late Preterm Infants
Neurophysiologic MaturationModerate and late preterm infants contribute to significant neonatal intensive care unit health care resource utilization because of their sheer numbers. Determinants of the length of hospitalization (LOH) in this population are understudied. Gestational age (GA) is used most commonly as a predictor for LOH but there are many limitations including inaccurate dating and morbidities of prematurity which at least partly related to neurophysiological immaturity. The latter can be assessed by amplitude integrated electroencephalogram (aEEG, a simplified 5 lead EEG), and possibly by heart rate variability (HRV) and respiratory variability (RV). All 3 are non-invasive tests that can be done at the bedside. Our study hypothesis is to determine if neurophysiologic maturation as assessed by aEEG, HRV and RV within 24-96 hours following birth improves the correlation between gestational age and length of hospitalization compared to gestational age alone.
Trial to Evaluate a Specified Type of Apgar (TEST-APGAR) Follow Up Study
Premature BirthMortality1 moreA specified version of the Apgar-Score, that can be used in newborns under resuscitation, was developed and its value to predict chronic damage in preterm infants will be tested.
Prediction of Spontaneous Preterm Birth by Cervical Elastogram
Preterm BirthBackground: Preterm birth is the leading cause of perinatal morbidity and mortality in multiple pregnancies. The medical and educational expenditure and lost productivity associated with preterm birth is very high. Sonoelastography is a new ultrasound technology which has enabled the measurement of tissue stiffness and it has been widely applied in assessment of breast lump and liver cirrhosis. Sonoelastography is potentially useful for the objective assessment of cervical consistency which could be related to risk of preterm birth. Objective: To assess the cervical consistency by shear wave elastography in prediction of preterm birth in multiple pregnancies. Setting: This is a prospective non-interventional observational study. Subjects: Chinese women carrying multiple pregnancies attending antenatal visit are invited to join the study. Method: Demographic data and antenatal history will be obtained. Transvaginal scan for the cervix will be performed by a trained researcher or obstetrician for the assessment of cervical consistency, cervical length, posterior cervical angle and fetal viability. The measurements will be repeated during 5 antenatal visits or separate study visits at 11-15, 16-19, 20-23, 24-27 and 28-32 weeks of gestation. At the end of pregnancy, the delivery data and neonatal outcome will be collected. Sample Size: The risk of preterm birth <34 weeks in twin pregnancies is approximately 20%. A sample size of 120 was determined as being sufficient to test the diagnostic performance of cervical elasticity in mid trimester assuming that the risk of preterm delivery <34 weeks vs >34 weeks is 1:5 and that cervical elasticity area under curve (AUC) of the receiver operating characteristics (ROC) curve was 0.7, with 80% power and alpha of 5%. Data Analysis: Changes in the cervical elastography will be compared using the Student paired two-tailed t test, and in the case of unequal standard deviation (SD), using a Wilcoxon signed-rank paired two-tailed test. For comparison of frequencies, Chi-square test, or a two-sided Fisher exact test will be used where appropriate. Linear regression will be used to assess the correlations. The level of statistical significance is set at p<0.05 (two-sided).
